CDW Holding Corporation ("CDW") is a Delaware corporation that has as its only significant asset all the outstanding common stock of WESCO Distribution, Inc., a Delaware corporation (together with its subsidiaries, "WESCO"). Hereinafter, "the Company" will refer to CDW and its subsidiaries. References herein to a "fiscal" year refer, in the case of the Company, to the year ended December 31 in the year indicated. Unless otherwise indicated, all information set forth in this Prospectus (i) gives effect to a to 1 split of CDW's Class A Common Stock, par value $0.01 per share ("Class A Common Stock"), and of the CDW's Class B Common Stock, par value $0.01 per share ("Class B Common Stock" and, together with the Class A Common Stock, the "Common Stock"), to be effected immediately prior to the effective date of the Registration Statement of which this Prospectus forms a part, (ii) assumes an initial public offering price of $ per share and (iii) assumes no exercise of the over-allotment options to be granted to the Underwriters by the Selling Stockholders. THE COMPANY WESCO is a leading full-line provider of products and related services in the electrical wholesale distribution industry with sales of $2.6 billion in 1997, an increase of more than $1 billion since 1993. With its blend of national capabilities and extensive local geographic coverage, WESCO specializes in developing combined product and service solutions tailored to meet the specific needs of each of its customers. WESCO is the second largest electrical wholesale distributor in North America and a leading consolidator in this highly fragmented, $67 billion industry. Through a network of approximately 330 branches located in 48 states and nine Canadian provinces, supported by five regional distribution centers, WESCO is able to serve virtually the entire U.S. and Canadian market. WESCO is particularly well positioned to meet the complex procurement needs of multi-site customers seeking total supply chain cost reduction through preferred alliances with fewer suppliers. WESCO offers a broad range of electrical, industrial and data communications products and services to a large and diversified customer base including (1) industrial companies from numerous manufacturing and process industries and original equipment manufacturers ("OEMs"), including manufacturers of factory- built homes and other modular structures, (2) contractors for industrial, commercial and residential projects, (3) investor-owned utilities, municipal power authorities and rural electric cooperatives and (4) commercial, institutional and governmental customers. WESCO maintains over 130,000 active customer accounts, and stocks and distributes over 210,000 products, sourced from over 6,000 suppliers, ranging from basic wire to advanced automation and control products. WESCO complements its product offerings with a range of services and procurement solutions, including integrated supply, where it manages all aspects of the customer's supply processes, and electronic commerce, where it employs technology to streamline business transactions. Since CDW acquired WESCO in 1994, management has realigned operations to achieve substantial growth in sales and profitability. Under its new leadership, WESCO (1) reconfigured its branch network to focus on key customer markets, (2) significantly expanded its National Accounts marketing program, (3) launched the industry's most active acquisition program and (4) implemented a new incentive system for branch managers and sales personnel. As a result of these actions, sales have increased to $2.6 billion in 1997 from $1.6 billion in 1993, a compound annual growth rate of 13.4%, and operating income has increased to $80.1 million in 1997 from a loss of $11.0 million in 1993. Since August 1995, WESCO has completed 13 acquisitions adding more than $650 million in annualized sales. 3

The electrical wholesale distribution industry in the United States is large, growing and highly fragmented. Industry sources estimate total electrical wholesale distributor sales at $67.3 billion for 1997, which represents a 10.2% compound annual growth rate over 1993 sales of $45.6 billion. The four largest wholesale distributors, including WESCO, control only 14% of total industry sales. No single distributor accounts for more than 5% of industry sales, and 57% of such sales are generated by distributors with less than $21 million in annual sales. In the United States, electrical distribution is still in the early stages of consolidation, unlike many other wholesale distribution industries which have undergone substantial consolidation in the past two decades. Customers now expect distributors to provide a broader package of products and services as they seek to outsource non-core functions and achieve measurable cost savings in purchasing, inventory and supply chain management. By virtue of its national and local capabilities, financial resources and focused acquisition strategy, WESCO believes that it has the opportunity to lead industry consolidation and capitalize on the growing customer demand for value-added services and procurement outsourcing. BUSINESS STRATEGY WESCO's mission is to become the preeminent wholesale distributor of electrical and other products in each of its chosen markets by tailoring its product and service offerings to meet the differing requirements of its targeted customers. WESCO's fundamental business goal is to achieve growth in sales and profitability that is consistently above the industry average, through marketing and acquisition initiatives, leveraging its fixed cost structure and purchasing power, and improving working capital management. To achieve that goal, WESCO's business strategy emphasizes six elements: . LEVERAGE NATIONAL COORDINATION AND SCALE. WESCO, with its national branch network in both the U.S. and Canada and the scale such network affords, has several competitive advantages, including (1) the ability to offer multi-site agreements with the scope required by National Accounts--major customers who seek to coordinate their maintenance, repair and operating ("MRO") supplies purchasing activity across multiple locations, (2) the ability to enter into favorable preferred supplier agreements which provide for improved payment terms, volume rebates, marketing programs and geographic franchises, (3) specialized and technical sales forces to meet specific customer needs in National Accounts, data communications, automation and control, energy management, integrated supply and major construction projects and (4) five regional distribution centers which allow same-day shipments of a broad range of products to branches and direct to customers. . ENCOURAGE LOCAL ENTREPRENEURSHIP AND FLEXIBILITY. A distributor's reputation is often determined at the local level, where timely supply and customer service are critical. Accordingly, WESCO grants its branch managers substantial autonomy in directing the branch sales force, configuring inventories, selecting markets served and developing local service options. WESCO's incentive system strongly encourages growth and profitability at the branch level, with a significant portion of the branch manager's compensation incentive based. While WESCO grants its branches a high degree of independence, they directly support and participate in national initiatives such as National Account sales, expansion of data communications product sales and marketing promotions with select manufacturers. . DELIVER VALUE-ADDED SERVICES. WESCO offers a comprehensive portfolio of supply management services designed to create measurable value for its customers, including (1) the assignment of on-site support personnel, (2) outsourcing of the entire MRO purchasing process, (3) inventory optimization programs, (4) participation in joint cost savings teams, (5) energy-efficient product upgrades, (6) safety and product training for customer employees and (7) process improvements using automation solutions. . FOCUS ON MARKETS WHERE WESCO HAS DEVELOPED DISTINCTIVE COMPETENCIES. WESCO has developed distinctive competencies in several markets by aligning its branch network by principal market served-- industrial/construction, utilities and manufactured structures. Business strategies, 4

specialized personnel and locally tailored inventories are designed to match each market's requirements. WESCO targets customers with large, complex service and supply requirements in all markets where specialized sourcing, project management and logistical support are needed. To serve such customers effectively, WESCO leverages its national capabilities, extensive local penetration and breadth of products and services offered. . DRIVE CONTINUOUS IMPROVEMENT IN PRODUCTIVITY AND PROFITABILITY. WESCO believes a successful business strategy must include a commitment to continuous improvement in productivity and profitability. WESCO is emphasizing the widespread use of innovative and disciplined approaches to managing its business processes, employee productivity and capital efficiency. These continuous improvement initiatives include (1) regular "zero based" re-evaluations of all facets of its business, (2) activity- based costing to more accurately measure and enhance profitability by customer, supplier and other categories, (3) enhanced coordination of inventory management among suppliers, branches and regional distribution centers, (4) benchmarking, using competitive analysis and world-class best practices to set appropriate standards for expense management, working capital and employee and overall productivity, (5) increased investment in targeted areas such as sales force management and company- wide training and development and (6) application of technology to enhance information and decision support systems. . LEAD INDUSTRY CONSOLIDATION. WESCO actively pursues acquisitions that complement its existing business. WESCO's acquisition strategy has been to (1) accelerate expansion into key growth markets, (2) add important new customers, (3) enhance sales of acquired branches by immediately broadening the product and service mix, (4) expand local presence to better serve existing customers, (5) increase scale and breadth of relationships with manufacturers and (6) leverage existing infrastructure. WESCO considers strategic acquisitions on a continuous basis. Since August 1995, WESCO has completed 13 acquisitions with 89 branch locations and annualized sales of more than $650 million. Furthermore, as a result of these acquisitions, WESCO has added major supplier relationships with Allen-Bradley, General Electric and Square D. STRATEGY FOR CONTINUED GROWTH WESCO has increased sales by more than $1 billion since year-end 1993, a compound annual growth rate in excess of 13%. WESCO's plans for continued growth are as follows: . EXPAND PRODUCT AND SERVICE OFFERINGS. WESCO intends to build on its demonstrated ability to introduce new products and services to meet customer demands and market opportunities. For example, WESCO plans to expand its presence in the fast-growing data communications market. In the past two years, WESCO has significantly increased its focus on this market, generating sales of $83 million in 1997. Led by its dedicated data communications sales team of approximately 70 people, and leveraging its general sales force, WESCO intends to expand sales to new and existing customers, as well as broaden its offering into other data communications product lines, such as outdoor wiring systems, active components and processors. In addition, WESCO plans to expand the number of integrated supply programs with new and existing accounts. Given the success of its integrated supply initiatives to date and the rapid growth in the demand for such services anticipated by industry sources, WESCO sees a major opportunity to develop additional customer relationships by leveraging its comprehensive service and supply expertise. . GROW NATIONAL PROGRAMS. WESCO has well-established National Account relationships with approximately 300 companies. National Accounts provide ongoing revenue through strategic multi-year agreements. WESCO believes that it can expand revenue generated by its National Accounts 5

program by (1) increasing its penetration of existing National Accounts, (2) shortening ramp-up time to full implementation, (3) adding new products to existing MRO agreements, (4) expanding agreements to include capital projects and (5) extending the program to new customers. In addition, through its Major Projects Group, WESCO plans to intensify its focus on large construction projects, such as new stadiums, industrial sites, wastewater treatment plants, airport expansions, healthcare facilities and prisons. WESCO intends to secure new contracts through (1) aggressive national marketing of its demonstrated project management capabilities, (2) further development of relationships with leading construction and engineering firms and (3) close coordination with National Account customers on their renovations and new construction projects. . GAIN SHARE IN KEY LOCAL MARKETS. WESCO has identified key geographic markets with a substantial base of potential customers and will use a combination of acquisitions, new branch openings and heightened sales and marketing efforts to gain market share. WESCO's executive marketing team, together with local branch managers, will work to expand WESCO's program of detailed market analysis and opportunity identification on a branch-by-branch and product line basis. In addition, WESCO intends to leverage relationships with preferred suppliers to increase sales of their products in local markets through various initiatives, including (1) sales promotions, (2) cooperative marketing efforts, (3) direct participation in National Accounts implementation, (4) dedicated sales forces and (5) product exclusivity. . EXECUTE ACQUISITION STRATEGY. WESCO intends to lead consolidation in the fragmented electrical wholesale distribution industry. Since adopting its acquisition strategy in August 1995, WESCO has been successful in adding more than $650 million in annualized sales, and will continue to evaluate acquisition opportunities to achieve the strategic objectives outlined under "Business Strategy." After the Offerings, the ability, where appropriate, to use its shares to finance acquisitions should give WESCO access to an expanded range of possible acquisitions. WESCO seeks acquisitions that will be accretive to earnings and will significantly complement the organic growth of the business. The 13 acquisitions completed by WESCO to date have collectively been accretive to its earnings. . ACCESS INTERNATIONAL OPPORTUNITIES. WESCO believes in a pragmatic and profitable expansion of sales outside the United States and Canada. WESCO intends to limit risk and maximize profit opportunities principally by following its National Account customers and key suppliers into their non-U.S. markets. For example, WESCO has opened a branch in Mexico City, where many current customers have plant operations and where WESCO has been granted the highly regarded Allen- Bradley franchise. Other opportunities to grow international sales include expanding the network of independent export sales representatives outside of North America, increasing the number of North American-based export sales offices and building closer relationships with global engineering, procurement and construction firms. 6

BACKGROUND CDW was formed by Clayton, Dubilier & Rice, Inc., a private investment firm ("CD&R"), in connection with the acquisition (the "Acquisition") from Westinghouse Electric Corporation, now known as CBS Corporation ("Westinghouse"), of its Westinghouse Electric Supply Company division, WESCO's predecessor (the "Predecessor"). The Acquisition was completed in February 1994. Upon completion of the Offerings, the Clayton & Dubilier Private Equity Fund IV Limited Partnership ("Fund IV"), a private investment fund managed by CD&R, will own approximately % of the then-outstanding Common Stock ( % assuming exercise of the Underwriters' overallotment options). The Predecessor was founded as a division of Westinghouse in 1922 for the purpose of selling and distributing Westinghouse electrical products and supplies. Since the Acquisition, WESCO has made a successful transition from being a division within a large corporation to an independent company. The Company's principal executive offices are located at Commerce Court, Suite 700, Four Station Square, Pittsburgh, Pennsylvania 15219, and its telephone number is (412) 454-2200. THE OFFERINGS The offering of shares of Class A Common Stock initially being offered in the United States and Canada (the "U.S. Offering") and the offering of shares of Class A Common Stock initially being offered outside the United States and Canada (the "International Offering") are referred to herein collectively as the "Offerings." The closing of the International Offering and of the U.S. Offering are each conditioned on the other.

See "Certain Transactions and Relationships--Westinghouse." Consolidated financial data of the Predecessor have been derived from the Predecessor's consolidated financial statements, which have been audited by the Predecessor's accountants. The Securities and Exchange Commission (the "Commission"), in Staff Accounting Bulletin Number 55 (SAB 55), requires that historical financial statements of a subsidiary, division or lesser business component of another entity include certain expenses incurred by the parent on its behalf. These expenses include officer and employee salaries; rent; depreciation; advertising; accounting and legal services; other selling, general and administrative expenses; and other such expenses. The financial statements of the Predecessor include such adjustments, estimates or allocations as the management of the Predecessor's parent company believed necessary to reflect these expenses. Because of (footnotes continued on following page) 8

such items, certain aspects of the consolidated results of operations for periods prior to the period beginning February 28, 1994 are not comparable with those for subsequent periods. (2) Consolidated financial data as of and for the years ended December 31, 1995, 1996 and 1997 have been derived from the Company's consolidated financial statements, which have been audited by Coopers & Lybrand L.L.P. (3) Presents adjusted combined results of operations of the Predecessor for the two months ended February 28, 1994 and of the Company for the ten months ended December 31, 1994. The adjusted combined operations data does not purport to represent what the Company's consolidated results of operations would have been if the Acquisition had actually occurred on January 1, 1994. (4) The Predecessor received a charge from its parent company in the form of interest expense for the portion of the parent company investment that, for internal reporting purposes, represented debt. For the year ended 1993 and the two months ended February 28, 1994, approximately 40% of the average parent company investment was considered to be debt for internal reporting purposes. The effective annual interest rate for all periods was approximately 10%. This method of reporting interest expense for internal reporting purposes is not necessarily indicative of the interest expense that would have been incurred had the Predecessor operated as a separate stand-alone entity. (5) Represents a charge, net of deferred taxes, for the cumulative effect of a change in accounting for postemployment benefits at January 1, 1993. (6) Represents a charge, net of taxes, relating to the write-off of unamortized debt issuance and other costs associated with the early termination of debt. (7) The Predecessor's results of domestic operations were included in the consolidated U.S. federal income tax return of its parent. The Predecessor's results of operations in Puerto Rico and certain operations in Canada were also included with other operations of the Predecessor's parent in the tax returns in those jurisdictions. For operations that did not pay their own income tax, the Predecessor's parent internally allocated income tax expense at the statutory rate after adjustment for state income taxes and several other items. The income tax expense and other tax-related information in the Predecessor's consolidated financial statements were calculated as if the Predecessor had not been eligible to be included in the consolidated tax returns of its parent (i.e., on a "stand-alone" basis). The calculation of tax provisions and deferred taxes necessarily required certain assumptions, allocations and estimates that the Predecessor's management believed were reasonable to accurately reflect the tax reporting for the Predecessor as if a stand-alone taxpayer. (8) For a description of the calculations of basic and diluted earnings per common share, see Note 2 to the consolidated financial statements included elsewhere in this Prospectus. (9) Defined as trade accounts receivable plus inventories less accounts payable. (10) Represents Redeemable Class A Common Stock as described in Note 9 to the consolidated financial statements. Under certain conditions, the holders thereof have the right to require the Company to repurchase all of the redeemable shares. As a result of this redemption feature, the Company has provided for a reduction in stockholders' equity to record the initial repurchase obligation. These repurchase rights terminate upon consummation of an initial public offering. The $9.0 million at December 31, 1997 will be reclassified upon consummation of the Offerings to increase paid-in capital. 9

CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS This Prospectus contains certain forward-looking statements regarding the business of the Company. When used in this Prospectus, the words "anticipates," "plans," "believes," "estimates," "intends," "expects" and similar expressions are intended to identify forward-looking statements. Such statements, including, but not limited to, the Company's statements regarding its business strategy, growth strategy, growth trends in the industry and various markets, acquisitions, international expansion, productivity and profitability enhancement, new product and service introductions and liquidity and capital resources are based on management's beliefs, as well as on assumptions made by, and information currently available to, management, and involve various risks and uncertainties, certain of which are beyond the Company's control. The Company's actual results could differ materially from those expressed in any forward-looking statement made by or on behalf of the Company. In light of these risks and uncertainties there can be no assurance that the forward- looking information will in fact transpire. Factors that might cause actual results to differ from such forward-looking statements include, but are not limited to, those discussed in "Risk Factors." The Company undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. ---------------- Market and market share data for the electrical wholesale industry are from Electrical Wholesaling magazine or Distributor Information Services Corporation, unless otherwise indicated. Except where specified, market share and market data do not include Canada. The Company believes such market share data are inherently imprecise, but are generally indicative of its relative market share. 10

RISK FACTORS Prospective purchasers of the Class A Common Stock should consider carefully the following factors relating to the Company and the Offerings, together with the other information and financial data set forth elsewhere in this Prospectus, prior to making an investment decision. GENERAL ECONOMIC CONDITIONS The electrical wholesale distribution industry is affected by changes in economic conditions, including national, regional and local slowdowns in construction and industrial activity, which are outside the control of the Company. The Company's operating results may also be adversely affected by increases in interest rates that may lead to a decline in economic activity, particularly in the construction market, while simultaneously resulting in higher interest payments by WESCO under its credit facilities. In addition, during periods of economic slowdowns WESCO's credit losses could increase significantly. There can be no assurance that economic slowdowns or adverse economic conditions or cyclical trends in certain customer markets will not have a material adverse effect on the Company's operating results and financial condition. COMPETITION The electrical wholesale distribution industry is highly competitive. In the United States, the industry is fragmented, while the much smaller Canadian market has achieved a high degree of concentration. WESCO competes directly with national and regional broad-based distributors, niche distributors carrying only specialized products, and small, local distributors with one or a few locations. Another source of competition in the wholesale channel is buying groups formed by smaller distributors to increase purchasing power and provide some limited cooperative marketing capability. The two largest of these are Affiliated Distributors, representing an estimated $5 billion of annual electrical wholesale distribution sales, and IMARK, representing an estimated $3 billion of annual sales, based on industry sources. While increased buying power may improve the competitive position of buying groups locally, the Company does not believe these groups have been able to compete effectively for National Account customers, due to the difficulty in coordinating a diverse ownership group. Outside the wholesale channel, manufacturers employ, and may increase the use of, direct sales representatives. In addition, some manufacturers with sufficient size, geographic scope and financial and marketing resources may be in a position to offer customers national account services. Finally, the development of alternative distribution channels, such as Internet-based catalogs, do-it- yourself ("DIY") retail outlets or a shift to direct sales and service by manufacturers, could have a material adverse effect on the wholesale distribution market and, as a result, the Company's performance. Some of WESCO's existing competitors have, and new market entrants may have, greater financial and marketing resources than WESCO. To the extent existing or future competitors seek to gain or retain market share by reducing prices, WESCO may be required to lower its prices, thereby adversely affecting financial results. Existing or future competitors also may seek to compete with WESCO for acquisitions, which could have the effect of increasing the price and reducing the number of suitable acquisitions, and may also compete with WESCO for start-up locations, thereby limiting the number of attractive locations for expansion. In addition, it is possible that competitive pressures resulting from the industry trend toward consolidation could affect growth and profit margins. See "Business--Competition." ABILITY TO IMPLEMENT AND MANAGE GROWTH STRATEGY; CAPITAL NEEDS FOR ACQUISITIONS A principal component of WESCO's strategy is to continue to expand through additional acquisitions and development of start-up locations that complement WESCO's operations in new or existing markets. The success of this strategy will depend upon WESCO's ability to identify, acquire and integrate a sufficient number of businesses. There can be no assurance that WESCO will be able to identify and acquire appropriate businesses on satisfactory terms or that future acquisitions will not have a material adverse effect on the Company's operating results, particularly during periods in which the operations of acquired businesses are being integrated into WESCO's operations. As part of its growth strategy, WESCO intends to build its international presence. 11

Significant expansion into international markets could involve risks relating to currency exchange rates, new and different legal, tax, accounting and regulatory requirements, difficulties in staffing and managing foreign operations, operating difficulties and other factors. In addition, profit margin and competitive position associated with sales transacted in foreign currency, such as sales in WESCO's Canadian operations, may be materially adversely affected by foreign exchange rates. See "Business--Growth Strategy." In order to implement its acquisition strategy, WESCO is likely to require additional funding. Future acquisitions could be financed by incurring additional indebtedness, including increased borrowing under WESCO's existing credit facilities, or by the issuance by CDW of additional equity securities. There can be no assurance, however, that adequate funding will be available on terms satisfactory to WESCO. As of December 31, 1997 the Company had total long-term debt of $294.3 million. An increase in the level of indebtedness of the Company could have important consequences for the holders of Class A Common Stock, including (1) increasing the portion of the Company's cash flow from operations being dedicated to the payment of principal and interest on indebtedness and unavailable for other purposes, (2) impairing WESCO's ability to obtain financing for working capital needs and general corporate purposes and (3) reducing WESCO's flexibility in responding to changes in business and economic conditions and competitive pressures. The issuance by CDW of additional equity securities may result in dilution to earnings to holders of the Class A Common Stock. See "Management's Discussion and Analysis of Financial Condition and Results of Operations--Liquidity and Capital Resources," "Business--Acquisitions" and "Description of Certain Indebtedness--Credit Facilities." DEPENDENCE ON KEY PERSONNEL WESCO is dependent upon the skills, experience and efforts of its Chief Executive Officer and other executive officers. Loss of the services of the Chief Executive Officer or one or more of the other executive officers could have a material adverse effect on WESCO's business and development. WESCO has no written employment contracts with any of its executive officers other than an employment agreement with its Executive Vice President, Industry Affairs. WESCO intends to enter into, prior to the Offerings, a three-year employment agreement with Roy W. Haley, its Chief Executive Officer and President, and a two-year employment agreement with David F. McAnally, its Chief Operating Officer, Chief Financial Officer and Treasurer. See "Management--Employment Agreements." WESCO's continued growth also depends in part on its continuing ability to attract and retain qualified managers, sales persons and other key employees and on its executive officers' ability to manage growth successfully. No assurance can be given that WESCO will be able to attract and retain such employees. WESCO has relied primarily upon CDW's stock option plan and other elements of compensation to retain key employees. WESCO intends, prior to the Offerings, to establish a long-term incentive plan for executives and other key management employees. See "Management--Stock Option Plan" and "Management--Long-Term Incentive Plan." KEY SUPPLIERS; MAINTENANCE OF SUPPLY; INTERRUPTION OF DISTRIBUTION CENTER OPERATIONS Consistent with industry practice, most of WESCO's agreements with suppliers (including both distribution agreements and preferred supplier agreements) are terminable by either party on no more than 60 days notice. WESCO's ten largest suppliers in 1997 accounted for 45% of WESCO's purchases for the period. The largest supplier was Eaton Corporation, through its Cutler-Hammer division, successor to the Distribution and Control Business Unit of Westinghouse, accounting for 18% of WESCO's purchases. The loss of, or a substantial decrease in the availability of, products from any of these suppliers, or the loss of key preferred supplier agreements, could have a material adverse effect on WESCO's business. In addition, supply interruptions could arise from shortages of raw materials, labor disputes or weather conditions affecting products or shipments, or other reasons beyond WESCO's control. An interruption of operations at any of WESCO's five distribution centers could have a material adverse effect on the operations of branches served by the affected distribution center. Further, there can be no assurance that particular products, or product lines, will be available to WESCO, or available in quantities sufficient to meet customer demand. Such limited product access could put WESCO at a competitive disadvantage. See "Business-- Suppliers and Purchasing" and "Business--Distribution Network." 12

DEPENDENCE ON INFORMATION SYSTEMS The Company believes that WESCO's computer systems are an integral part of its business and growth strategies. WESCO depends on its information systems to process orders, manage inventory and accounts receivable collections, purchase products, ship products among its branches on a timely basis, maintain cost-effective operations and provide superior service to its customers. Although the Company believes WESCO has the appropriate disaster recovery plans in place, there can be no assurance that a serious disruption in the operation of WESCO's information systems will not occur. Any such disruption could have a material adverse effect on the Company's business and results of operations. See "Business--Management Information Systems." CERTAIN INVENTORY RISKS The obsolescence of a significant amount of inventory due to changes in customer preferences or technological improvements could have a material adverse effect on the Company's business and results of operations. WESCO believes that this risk is confined principally to data communications products, which are the most likely to be subject to obsolescence resulting from rapid technological change. At December 31, 1997, these products constituted less than 6% of inventory. ENVIRONMENTAL RISKS The Company's facilities and operations are subject to federal, state and local laws and regulations relating to environmental protection ("Environmental Laws") and health and human safety. Certain of these laws and regulations may impose strict, joint and several liability on certain persons for the cost of investigation or remediation of contaminated properties, meaning that a person could be liable for more than its pro rata share of such costs regardless of fault. These persons may include present or future owners and operators of properties, and persons that arranged for the disposal of hazardous substances. In addition, the disposal of certain products distributed by WESCO, such as ballasts, fluorescent lighting and batteries, must comply with Environmental Laws. In connection with the Acquisition, Westinghouse agreed to indemnify the Company for certain liabilities under Environmental Laws resulting from conditions at the Predecessor's branch locations and other real property at the time of the Acquisition. By the terms of this indemnity, the Company is not entitled to indemnification for claims made under the indemnity after February 27, 1996. Based on its due diligence investigation, including environmental assessments, CDW made a claim under this indemnity in the amount of approximately $1.5 million, which Westinghouse is disputing. In connection with its acquisition program, WESCO acquires new branch locations, including owned and leased real property which may carry with it certain liabilities under Environmental Laws. It is WESCO's practice to conduct due diligence investigations in connection with such acquisitions, including environmental assessments, and, where appropriate, to provide for contractual indemnities. However, no assurance can be given that the Company will not become subject to liabilities for environmental matters, including with respect to conditions at its properties, that such liabilities will not be material or that, where negotiated, contractual indemnities will be sufficient to cover such liabilities. RESTRICTIONS IMPOSED BY LENDERS WESCO's existing credit facilities and certain mortgage notes issued to Westinghouse in connection with the Acquisition (the "Mortgage Notes") contain covenants that limit WESCO with respect to certain business matters. Such covenants include, among other things, limitations on the acquisition of new subsidiaries, the sale of assets, the incurrence of additional debt and the payment of dividends. In addition, WESCO's senior credit facility requires WESCO to meet certain financial tests based on net worth, a funded indebtedness to consolidated EBITDA ratio and a fixed charge coverage ratio. See "Description of Certain Indebtedness." PRINCIPAL STOCKHOLDER Upon completion of the Offerings, Fund IV will own approximately % of the then outstanding Common Stock of CDW and will retain the power to control the Company's corporate policies, the election of 13

persons constituting its management and Board of Directors, and the outcome of corporate actions requiring stockholder approval. Immediately after the Offerings, three of the Company's nine directors will be principals of CD&R. In addition, following the Offerings, Fund IV will continue to have a contractual right to appoint an observer to attend meetings of the Board of Directors of the Company. See "Management--Directors and Executive Officers," "--Compensation Committee Interlocks and Insider Participation," "Certain Transactions and Relationships" and "Security Ownership by Management and Principal Stockholders." SHARES ELIGIBLE FOR FUTURE SALE Upon completion of the Offerings, shares of Class A Common Stock will be issued and outstanding and shares of Class A Common Stock will be issuable upon the exercise of outstanding stock options. After the expiration of a 180- day "lock-up" period to which substantially all of CDW's current stockholders and option holders are subject, such holders will in general be entitled to dispose of their shares (including the shares underlying such options), although the shares of Class A Common Stock held by Fund IV and other affiliates of CDW will continue to be subject to the volume and other restrictions of Rule 144 under the Securities Act of 1933, as amended (the "Securities Act"). Sales of substantial amounts of Class A Common Stock, or the perception that such sales could occur at the expiration of such 180-day period, may materially adversely affect the market price of the Class A Common Stock prevailing from time to time. In addition, under the Registration and Participation Agreement, dated as of February 28, 1994 (the "Registration and Participation Agreement"), among CDW, Fund IV and the existing stockholders of CDW, CDW's existing stockholders and option holders have certain demand registration rights and "piggy-back" registration rights in connection with future offerings of Class A Common Stock. See "Shares Eligible for Future Sale" and "Underwriting." NO PRIOR PUBLIC MARKET; POSSIBLE VOLATILITY OF STOCK PRICE Prior to the Offerings, there has been no public market for the Class A Common Stock. Although CDW will make an application for listing the Class A Common Stock on the New York Stock Exchange, no assurance can be given that an active trading market will be created or sustained. The initial public offering price will be determined by negotiations among CDW, the Selling Stockholders and representatives of the Underwriters based on several factors and will not necessarily reflect the market price of the Class A Common Stock following the Offerings. Due to the absence of any prior public market for the shares of Class A Common Stock, there can be no assurance that the initial public offering price will correspond to the price at which the shares of Class A Common Stock will trade in the public market subsequent to the Offerings. See "Underwriting." The market price for shares of the Class A Common Stock may be volatile and may fluctuate based upon a number of factors including, but not limited to, the Company's operating performance, news announcements or changes in general economic and market conditions. In addition, the stock market in recent years has experienced extreme price and volume fluctuations that often have been unrelated or disproportionate to the operating performance of companies. These fluctuations may materially adversely affect the market price of the Class A Common Stock. DILUTION Purchasers of Class A Common Stock in the Offerings will experience immediate and substantial dilution in the net tangible book value of their Class A Common Stock. At an initial public offering price of $ per share, purchasers of shares in the Offerings will experience dilution in net tangible book value of $ per share. See "Dilution." 14

USE OF PROCEEDS The Company will not receive any proceeds from the sale of shares by the Selling Stockholders. At the time of the Acquisition, the Company agreed to assume the costs of the Offerings (other than the underwriting discount) and to pay certain fees and expenses in connection with the sale of shares by the Selling Stockholders. See "Selling Stockholders." DIVIDEND POLICY CDW has never declared or paid any dividends on the Class A Common Stock and has no current plans to pay dividends on the Class A Common Stock. The Company presently intends to retain earnings to support the growth of its business. The payment of any future dividends will be determined by the Board of Directors in light of conditions then existing, including the Company's earnings, financial condition and capital requirements, restrictions in financing agreements, business conditions, certain corporate law requirements and other factors. CDW is a holding company and thus its ability to pay dividends on the Class A Common Stock depends on its subsidiaries' ability to pay dividends to CDW. The Company's financing agreements generally restrict the payment of dividends by CDW's subsidiaries to CDW or by CDW to its shareholders. See "Description of Certain Indebtedness." 15

CAPITALIZATION The following table sets forth the consolidated capitalization of the Company as of December 31, 1997. This table should be read in conjunction with the consolidated financial statements and the notes thereto included elsewhere in this Prospectus.

See "Description of Certain Indebtedness--Acquisition Notes." (2)Does not include $59.5 million of debt incurred to consummate the Avon and Brown acquisitions in January 1998, of which up to $5.0 million may be converted to Shares of Class A Common Stock at the initial public offering price. (3)Does not include shares of Class A Common Stock issuable upon the exercise of stock options outstanding at December 31, 1997. See "Management--Stock Option Plan." 16

DILUTION As of December 31, 1997 CDW's pro forma net tangible book value was $ or $ per share, after giving effect to (i) the termination of the redemption feature of certain common shares upon the consummation of the Offerings and (ii) the issuance of shares of Class A Common Stock upon the conversion of certain convertible notes issued in connection with prior acquisitions, which by their terms will mandatorily convert into shares of Class A Common Stock at the initial public offering price upon consummation of the Offerings (the "Acquisition Notes"). After giving effect to estimated expenses of $ million payable by the Company in connection with the Offerings, pro forma net tangible book value of CDW at December 31, 1997 would have been $ million or $ per share of Common Stock. Assuming an initial public offering price of $ per share of Class A Common Stock, there would have been an immediate dilution of $ per share to purchasers of the shares of Class A Common Stock in the Offerings ("New Investors"). Dilution is determined by subtracting adjusted net tangible book value per share after the Offerings from the amount of cash paid by a New Investor for one share of Class A Common Stock. The following table illustrates the per share dilution: Initial public offering price per share........................... $ Pro forma net tangible book value per share before the Offerings (1).............................................................. $ Decrease in net tangible book value per share attributable to the Offerings........................................................ --- Pro forma net tangible book value per share after the Offerings... --- Dilution per share to New Investors............................... $ - -------- (1) Net tangible book value per share as of a specified date represents net tangible assets (total tangible assets less total liabilities) divided by the number of shares of Class A Common Stock assumed to be then outstanding. The following table summarizes on a pro forma basis as of December 31, 1997, after giving effect to the issuance of Class A Common Stock upon conversion of the Acquisition Notes in connection with the Offerings, the differences between the existing stockholders and the New Investors with respect to the number of shares of Class A Common Stock purchased, the total consideration paid and the average price paid per share.

SELECTED FINANCIAL DATA The following table sets forth (i) selected historical consolidated financial data of the Predecessor as of and for the year ended December 31, 1993 and as of and for the two months ended February 28, 1994 and (ii) selected historical consolidated financial data of the Company as of and for the ten months ended December 31, 1994, as of and for the years ended December 31, 1995, 1996 and 1997, which have been derived from audited financial statements. The selected historical consolidated financial data of the Predecessor have been derived from the Predecessor's financial statements, which have been audited by the Predecessor's accountants. The selected historical consolidated financial data of the Company as of and for the years ended December 31, 1995, 1996 and 1997 have been derived from the Company's consolidated financial statements, which have been audited by Coopers & Lybrand L.L.P. The adjusted combined selected data for 1994 combines the audited results of operations of the Predecessor for the two months ended February 28, 1994 and of the Company for the ten months ended December 31, 1994. The adjusted combined selected data for the year ended December 31, 1994 does not purport to represent what the Company's consolidated results of operations would have been if the Acquisition had actually occurred on January 1, 1994. See the Consolidated Financial Statements of the Company and the accompanying notes thereto included elsewhere in this Prospectus and "Management's Discussion and Analysis of Financial Condition and Results of Operations." 18

See "Certain Transactions and Relationships--Westinghouse." Consolidated financial data of the Predecessor have been derived from the Predecessor's consolidated financial statements, which have been audited by the Predecessor's accountants. The Commission, in Staff Accounting Bulletin Number 55 (SAB 55), requires that historical financial statements of a subsidiary, division or lesser business component of another entity include certain expenses incurred by the parent on its behalf. These expenses include officer and employee salaries; rent; depreciation; advertising; accounting and legal services; other selling, general and administrative expenses; and other such expenses. The financial statements of the Predecessor include such adjustments, estimates or allocations as the management of the Predecessor's parent company believed necessary to reflect these expenses. Because of such items, certain aspects of the consolidated results of operations for periods prior to the period beginning February 28, 1994 are not comparable with those for subsequent periods. (footnotes continued on following page) 19

(2) Presents adjusted combined results of operations of the Predecessor for the two months ended February 28, 1994 and of the Company for the ten months ended December 31, 1994. The adjusted combined operations data does not purport to represent what the Company's consolidated results of operations would have been if the Acquisition had actually occurred on January 1, 1994. (3) The Predecessor received a charge from its parent company in the form of interest expense for the portion of the parent company investment that, for internal reporting purposes, represented debt. For the year ended 1993 and the two months ended February 28, 1994, approximately 40% of the average parent company investment was considered to be debt for internal reporting purposes. The effective annual interest rates for all periods was approximately 10%. This method of reporting interest expense for internal reporting purposes is not necessarily indicative of interest expense that would have been incurred had the Predecessor operated as a separate stand-alone entity. (4) Represents a charge, net of deferred taxes, for the cumulative effect of a change in accounting for postemployment benefits at January 1, 1993. (5) Represents a charge, net of taxes, relating to the write-off of unamortized debt issuance and other costs associated with the early termination of debt. (6) The Predecessor's results of domestic operations were included in the consolidated U.S. federal income tax return of its parent. The Predecessor's results of operations in Puerto Rico and certain operations in Canada were also included with other operations of the Predecessor's parent in the tax returns in those jurisdictions. For operations that did not pay their own income tax, the Predecessor's parent internally allocated income tax expense at the statutory rate after adjustment for state income taxes and several other items. The income tax expense and other tax-related information in the Predecessor's consolidated financial statements were calculated as if the Predecessor had not been eligible to be included in the consolidated tax returns of its parent (i.e., on a "stand-alone" basis). The calculation of tax provisions and deferred taxes necessarily required certain assumptions, allocations and estimates that the Predecessor's management believed were reasonable to accurately reflect the tax reporting for the Predecessor as if a stand-alone taxpayer. (7) For a description of the calculations of basic and diluted earnings per common share, see Note 2 to the consolidated financial statements included elsewhere in this Prospectus. (8) Defined as trade accounts receivable plus inventories less accounts payable. (9) Represents Redeemable Class A Common Stock as described in Note 9 to the consolidated financial statements. Under certain conditions, the holders thereof have the right to require the Company to repurchase all of the redeemable shares. As a result of this redemption feature, the Company has provided for a reduction in stockholders' equity to record the initial repurchase obligation. These repurchase rights terminate upon consummation of an initial public offering. The $9.0 million at December 31, 1997 will be reclassified upon consummation of the Offerings to increase paid-in capital. 20

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS GENERAL WESCO is the second largest electrical wholesale distributor in North America with approximately 330 branches located in 48 states and nine Canadian provinces. The Company sells over 210,000 products, sourced from over 6,000 suppliers, to more than 130,000 active customers. WESCO complements its product offerings with a range of services and procurement solutions. Growth in revenue is dependent upon several factors, including industry trends, general economic conditions and the ability of the Company to grow market share and consummate acquisitions. From 1993 to 1997 the Company's sales rose by 13.4% on a compound annual basis, while industry sales grew at a compound annual rate of 10.2% during the same period. The Company's ability to outpace the growth in the industry has resulted primarily from the launching of an aggressive acquisition program, which has added more than $650 million in annualized sales since August 1995. The majority of these acquisitions occurred during and after 1996 and, as such, have had a greater effect on periods beginning with 1996. The Company's sales can be categorized as stock sales, special orders or direct shipments. Stock sales are filled directly from branch inventory and over the past three years represented 40% to 50% of total sales. Direct ship orders are shipped to the customer by the manufacturer since generally they involve large orders or products that are too bulky to be easily handled and over the past three years represented 35% to 45% of total sales. Special orders are for products that are not ordinarily stocked in branch inventories and are ordered from the manufacturer pursuant to a customer's request. Special orders represent the remainder of total sales. Gross profit margins on stock and special order sales are approximately 50% higher than those on direct ship sales. Although direct ship margins are lower, operating profits are comparable since the inventory and handling costs associated with direct shipments are lower. The Company pays its sales force commissions based on a standard percent of billing margin dollars. Since stock and special order sales are typically at higher gross profit margins than direct ship sales, the commissions paid are also higher as a percent of sales. Since CDW acquired WESCO in early 1994, the Company has experienced a significant improvement in its income from operations, which has more than doubled from 1.3% of sales in 1994 to 3.1% of sales in 1997. This margin improvement has resulted primarily from (1) better leveraging of the Company's existing infrastructure due to growth in sales, (2) focusing on higher margin products and services such as National Accounts and (3) acquisitions of companies with average operating margins in excess of that for WESCO's existing business. At December 31, 1997, the Company's net adjusted working capital investment was $338.8 million, composed of $351.2 million in accounts receivable and $299.4 million in inventory, offset by $311.8 million in accounts payable. The Company is implementing a number of initiatives designed to improve its working capital performance, primarily in the area of inventory management. Such initiatives include (1) coordinating purchasing and inventory investment activities among groups of branches or "districts," (2) upgrading the logic of the automated stock replenishment programs used to supply branches from the distribution centers, (3) negotiating improved inventory return and consignment arrangements with important suppliers, (4) increasing the use of preferred suppliers and (5) shortening and stabilizing lead times between order and delivery from suppliers. The Company has historically financed its acquisitions, new branch openings, working capital needs and capital expenditures through internally generated cash flow and borrowings under its credit facilities. During the initial phase of an acquisition or new branch opening, the Company typically incurs expenses related to installing or converting information systems, training employees and other initial operating activities. In some acquisitions, the Company may incur expenses in connection with the closure of any of its own redundant branches. Historically, the costs associated with opening new branches, and closing branches in connection with certain acquisitions, have not been material. The Company has accounted for its acquisitions under the purchase method of accounting. 21

RESULTS OF OPERATIONS The following table sets forth the percentage relationship to net sales of certain items in the Company's Statement of Income for the periods presented: YEAR ENDED DECEMBER 31, ------------------------- 1995 1996 1997 ------- ------- ------- Sales, net...................................... 100.0% 100.0% 100.0% Gross profit.................................... 17.3 17.8 17.9 Selling, general and administrative expenses.... 14.3 14.8 14.8 ------- ------- ------- Income from operations.......................... 3.0 3.0 3.1 Interest expense................................ 0.9 0.8 0.8 ------- ------- ------- Income before income taxes...................... 2.1 2.2 2.3 Income taxes.................................... 0.8 0.8 0.9 ------- ------- ------- Income before extraordinary charge.............. 1.3 1.4 1.4 Extraordinary charge, net of taxes.............. 0.4 -- -- ------- ------- ------- Net income...................................... 0.9% 1.4% 1.4% ======= ======= ======= 1997 COMPARED TO 1996 NET SALES. Sales for the year ended December 31, 1997 were $2,594.8 million, compared with $2,274.6 million for the year ended December 31, 1996. This represented an increase of $320.2 million, or 14.1%. Sales of comparable branches (those open throughout both periods) rose 7.0%, with branches in the United States and Canada increasing 7.1% and 5.9%, respectively. Within the United States, the branches with a high volume of sales to utility customers experienced a somewhat higher level of comparable branch sales. In addition to growth in sales of comparable branches, the remaining sales increase resulted primarily from the nine companies acquired since the beginning of 1996. Sales of product from stock rose 21%, as compared to the prior period, increasing the mix of stock sales three percentage points to 48% of total sales. This was a result of several ongoing initiatives designed to increase stock sales, such as the continued emphasis on growing National Account sales, and, to a lesser extent, the impact of acquired company sales, which have tended to have a higher mix of stock sales. Direct ship sales rose 4% over the prior period. This sales increase was below that experienced by the Company in other areas and was primarily due to the slower growth in the non-residential construction market for commercial and industrial projects, which constitutes the majority of direct ship sales. GROSS PROFIT. Gross profit for the year ended December 31, 1997 was $463.9 million, compared with $405.0 million for 1996. The increase of $58.9 million, or 14.5%, was primarily due to the higher sales volume in 1997 from both acquisitions and comparable branch operations. Gross profit as a percentage of sales increased to 17.9% in 1997 from 17.8% in 1996. In 1996, approximately $9.3 million of gross profit was recorded in connection with a one-time international construction project with a gross profit margin that was higher than the Company's usual margins on large construction projects due to service requirements and risk considerations associated with the order. Without this international order, the Company's gross profit margin would have been 17.6% in 1996, compared to 17.9% for 1997. The increase in the gross profit margin was primarily due to the increase in the mix of higher margin stock sales, including sales associated with acquired companies. SELLING, GENERAL AND ADMINISTRATIVE EXPENSES (INCLUDING DEPRECIATION AND AMORTIZATION). Selling, general and administrative ("SG&A") expenses for the year ended December 31, 1997 were $383.8 million, compared with $336.8 million in 1996. This increase of $47.0 million, or 14.0%, was primarily due to expenses associated with the companies acquired in 1997 and 1996. SG&A expenses as a percentage of sales remained unchanged at 14.8%. Acquisitions with higher SG&A expense rates were offset by cost containment in the Company's core business, as well as cost reductions in the acquired companies. Depreciation and amortization increased by $0.5 million as a result of recent acquisitions. INTEREST EXPENSE. Interest expense increased by $2.7 million primarily due to the higher levels of borrowings outstanding associated with the acquisitions made since the beginning of 1996, partially offset by lower interest rates during 1997. 22

INCOME TAXES AND NET INCOME. The effective tax rate was 39.6% for the year ended December 31, 1997 compared to 36.1% for the same period in 1996. The increase in the effective tax rate was primarily due to the reduction of a valuation allowance for deferred tax assets in 1995 and 1996, which had the effect of reducing the income tax rate during those periods. The Company began its operations as a stand-alone entity in early 1994 with no history of generating taxable income. Accordingly, a valuation allowance was established for the net deferred tax assets that were generated during 1994. In 1995 and 1996, as the Company subsequently demonstrated an ability to utilize such deferred tax assets, the valuation allowance was reduced and had the effect of reducing the effective tax rate for both 1995 and 1996. Since the valuation allowance was reduced to zero during 1996, there was no similar effect on the 1997 tax rate. Net income in 1997 increased $3.7 million, or 11.4%, to $36.2 million from $32.5 million in 1996, primarily as a result of the increase in gross profit, partially offset by the increase in operating expenses and a higher effective tax rate. 1996 COMPARED TO 1995 NET SALES. Sales for the year ended December 31, 1996 were $2,274.6 million, an increase of $417.6 million, or 22.5%, from $1,857.0 million for the year ended December 31, 1995. Approximately 74% of the sales increase was attributable to the seven acquisitions made during 1996 as well as the full- year effect of the two acquisitions made in the second half of 1995. The balance of the sales increase was due to the continued growth in the base of the existing business, with no significant differences in the growth rates of the various markets. Comparable branch sales increased 3.8% during the period, with branches in the United States increasing at a 5.1% rate and Canada declining at a 3.0% rate, reflecting a decline in the Canadian market overall, particularly for the construction project business. GROSS PROFIT. Gross profit for 1996 of $405.0 million increased 26.2%, or $84.0 million, over the $321.0 million recorded in 1995. The increase in gross profit was primarily due to the increase in sales discussed above. As a percent of sales, gross profit increased to 17.8% in 1996 from 17.3% in 1995. The one-time international construction project discussed above increased the gross profit margin by 0.2 percentage points. Without this project, the Company's gross profit margin would have been 17.6% in 1996. The remainder of this increase in the gross profit margin was attributable to the higher mix of stock sales in the acquired companies, which sales typically have higher margins. SELLING, GENERAL AND ADMINISTRATIVE EXPENSES (INCLUDING DEPRECIATION AND AMORTIZATION). SG&A expenses increased $71.5 million, or 27.0%, to $336.8 million in 1996 from $265.3 million in 1995. This increase was primarily due to the expenses associated with the acquisitions discussed above, including $1.7 million of additional amortization of goodwill. As a percent of sales, SG&A expenses increased to 14.8% in 1996 from 14.3%. This increase was primarily due to the higher expense rate of the acquired companies, typically associated with their higher stock sales mix. INTEREST EXPENSE. Interest expense increased $1.6 million in 1996 to $17.4 million from $15.8 million in 1995 primarily due to the increased level of borrowings outstanding as a result of the nine companies acquired in 1995 and 1996, partially offset by lower interest rates during 1996. INCOME TAXES AND INCOME BEFORE EXTRAORDINARY CHARGE. The effective tax rate was 36.1% for 1996, compared to 37.0% for 1995. Income before extraordinary charge increased $7.4 million, or 29.5%, to $32.5 million in 1996 from $25.1 million in 1995. This increase was due to the higher sales and gross profit partially offset by the higher selling, general and administrative expenses discussed above. EXTRAORDINARY CHARGE. During 1996, the Company refinanced its revolving credit facilities and, as a result, wrote off $8.1 million, representing unamortized debt issuance costs net of applicable taxes. LIQUIDITY AND CAPITAL RESOURCES The Company's liquidity needs arise from seasonal working capital requirements, capital expenditures, interest and principal payment obligations and acquisitions. The Company has historically met its liquidity and capital investment needs with internally generated funds and borrowings under its existing credit facilities. 23

For the year ended December 31, 1997, cash used for operating activities was $11.1 million compared to cash provided by operating activities of $15.2 million for the year ended December 31, 1996. The cash used for operating activities was primarily due to the $54.6 million increase in certain components of net working capital offset by the $36.2 million in net income. The $32.6 million increase in receivables was, for the most part, due to the increased level of sales. The $31.7 million increase in inventories was due, in part, to the increased sales and to the increase in the mix of stock sales. Also, the Company increased its inventory investment in its five regional distribution centers by $13.8 million during 1997, primarily in connection with the addition of certain supplier lines historically purchased directly by the branches. This initial increase will be offset as the Company reduces its existing investment in those supplier lines at the branch locations. Net cash used in investing activities was $22.4 million for the year ended December 31, 1997, compared to $111.0 million for the year ended December 31, 1996. The primary reason for the cash used in investing activities for the periods presented was acquisitions. The Company used $13.9 million and $103.9 million for acquisitions in the periods ended December 31, 1997 and 1996, respectively. The decrease was due to the reduced number of completed acquisitions in 1997 versus 1996. The Company's capital expenditures, excluding acquisitions, for the year ended December 31, 1997 were $12.4 million as compared to $9.4 million for the year ended December 31, 1996. Such capital expenditures were primarily for branch and distribution center facility improvements, forklifts and delivery vehicles and computer equipment and software. The increase in such expenditures reflects the necessary investments in fixed assets to position the Company for its growth plans. Capital expenditures for fiscal 1998 are expected to total approximately $14.0 million. The Company is in the process of modifying, upgrading or replacing its computer software applications and systems to accommodate the "Year 2000" changes required for correct recording of dates in the year 2000 and beyond. The Company does not expect that the cost of its Year 2000 compliance program will be material to its financial condition or results of operations. The Company believes that it will be able to achieve compliance by early 1999, and does not currently anticipate any material disruption in its operations. The Company does not currently have any information concerning the compliance status of its suppliers and customers. In the event that any of the Company's significant suppliers or customers do not successfully achieve Year 2000 compliance, the Company's business or operations could be adversely affected. Cash provided by financing activities decreased $46.1 million to $41.1 million for the year ended December 31, 1997 compared to $87.2 million for the year ended December 31, 1996. The decrease was due to reduced borrowings as a result of fewer completed acquisitions. At December 31, 1997, the Company had total long-term debt of $294.3 million. This indebtedness consisted of $226.2 million under existing credit facilities, $65.3 million associated with two mortgage notes issued to Westinghouse in connection with the Acquisition, and $2.8 million of notes in connection with certain acquisitions. The weighted average interest rate on the credit facilities at December 31, 1997 was 6.7%. This rate fluctuates with the LIBOR, Bankers Acceptance and Prime based lending rates. The Company funded the $59.5 million aggregate purchase price of two acquisitions that closed in January 1998 through $45.0 million of borrowings under its credit facilities and the issuance of $14.5 million of its unsecured notes, maturing by mid-1999. The mortgage notes mature in February 2001 with interest at approximately 8% per annum, which is computed semi-annually and added to the principal amount of the mortgage notes. In February 1998, the Company amended certain terms and conditions of its existing credit facilities. The amendment included provisions that permit the Company to borrow up to a maximum of $445 million and release all previously required collateral. The existing credit facilities expire in February 2001 and have no principal payment requirements prior to that date. Management believes that the Company has adequate resources and liquidity to meet its borrowing obligations, fund all required capital expenditures and pursue its business strategy for existing operations for the foreseeable future. However, the Company may require additional funding in order to pursue significant acquisition opportunities. Such acquisitions may be financed by bank borrowings, public offerings or private 24

placements of equity or debt securities or a combination of the foregoing and may require the consent of the Company's existing lenders. There can be no assurance that the Company will be able to obtain such funds to finance significant future acquisitions. INFLATION The rate of inflation, as measured by changes in the consumer price index, did not have a material effect on the sales or operating results of the Company during the periods presented. However, inflation in the future could affect the Company's operating costs. Price changes from suppliers have historically been consistent with inflation and have had little impact on the Company's profitability. SEASONALITY The Company's operating results are affected by certain seasonal factors. Sales are typically at their lowest during the first quarter due to a reduced level of construction activity during the winter months. Sales increase during the warmer months beginning in March and continuing through November. Sales drop again slightly in December as the weather cools and also as a result of reduced level of activity during the holiday season. As a result, the Company reports sales and earnings in the first quarter that are generally lower than that of the remaining quarters. QUARTERLY INFORMATION The following table presents unaudited quarterly operating results for each of the Company's last eight quarters as well as the percentage of the Company's sales represented by each item. This information has been prepared by the Company on a basis consistent with the Company's audited financial statements and includes all adjustments (consisting only of normal recurring adjustments) that management considers necessary for a fair presentation of the data. These quarterly results are not necessarily indicative of future results of operations. This information should be read in conjunction with the Company's consolidated financial statements and Notes thereto included elsewhere in this Prospectus.

This Statement, which is effective for the 1997 financial statements, establishes standards for computing and presenting earnings per share ("EPS") and requires restatement of all prior period EPS data presented. The provisions of SFAS No. 128 have been adopted and the effects are included in the financial statements included elsewhere in this Prospectus. In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive Income," which establishes standards for reporting and displaying comprehensive income and its components. This Statement requires that all items that are required to be recognized under accounting standards as components of comprehensive income 25

be reported in a financial statement that is displayed with the same prominence as other financial statements. Additionally, the FASB issued SFAS No. 131, "Disclosures about Segments of an Enterprise and Related Information," which establishes standards for the way that public business enterprises report information about operating segments in annual financial statements and related disclosures about products and services, geographic areas and major customers. These statements are effective for financial statements for fiscal years beginning after December 15, 1997. Management is currently evaluating the implications of these statements. 26

BUSINESS THE COMPANY WESCO is a leading full-line provider of products and related services in the electrical wholesale distribution industry with sales of $2.6 billion in 1997, an increase of more than $1 billion since 1993. With its blend of national capabilities and extensive local geographic coverage, WESCO specializes in developing combined product and service solutions tailored to meet the specific needs of each of its customers. WESCO is the second largest electrical wholesale distributor in North America and a leading consolidator in this highly fragmented, $67 billion industry. Through a network of approximately 330 branches located in 48 states and nine Canadian provinces, supported by five regional distribution centers, WESCO is able to serve virtually the entire U.S. and Canadian market. WESCO is particularly well positioned to meet the complex procurement needs of multi-site customers seeking total supply chain cost reduction through preferred alliances with fewer suppliers. WESCO offers a broad range of electrical, industrial and data communications products and services to a large and diversified customer base including (1) industrial companies from numerous manufacturing and process industries and original equipment manufacturers ("OEMs"), including manufacturers of factory- built homes and other modular structures, (2) contractors for industrial, commercial and residential projects, (3) investor-owned utilities, municipal power authorities and rural electric cooperatives and (4) commercial, institutional and governmental customers. WESCO maintains over 130,000 active customer accounts, and stocks and distributes over 210,000 products, sourced from over 6,000 suppliers, ranging from basic wire to advanced automation and control products. WESCO complements its product offerings with a range of services and procurement solutions, including integrated supply, where it manages all aspects of the customer's supply process, and electronic commerce, where it employs technology to streamline business transactions. Since CDW acquired WESCO in 1994, management has realigned operations to achieve substantial growth in sales and profitability. Under its new leadership, WESCO (1) reconfigured its branch network to focus on key customer markets, (2) significantly expanded its National Accounts marketing program, (3) launched the industry's most active acquisition program and (4) implemented a new incentive system for branch managers and sales personnel. As a result of these actions, sales have increased to $2.6 billion in 1997 from $1.6 billion in 1993, a compound annual growth rate of 13.4%, and operating income has increased to $80.1 million in 1997 from a loss of $11.0 million in 1993. Since August 1995, WESCO has completed 13 acquisitions adding more than $650 million in annualized sales. In addition, for information about the Company by geographic area, see Note 17 to the company's consolidated financial statements. INDUSTRY OVERVIEW The electrical wholesale distribution industry serves customers in the industrial, commercial, construction and utility markets. Electrical wholesalers provide logistical and technical services for customers by bundling together a wide range of products typically required for the construction and maintenance of electrical supply networks, including wire, lighting, distribution and control equipment and a wide variety of electrical supplies. The wholesale channel enables customers to efficiently access a broad range of products and has the capacity to deliver value-added services. Customers now expect distributors to provide a broader and more complex package of services as they seek to outsource non-core functions and achieve measurable cost savings in purchasing, inventory and supply chain management. As a result, electrical wholesalers have approximately doubled their share of total electrical products sold in the United States during the period 1972 to 1997, and sales by electrical wholesalers now represent approximately 60% of the U.S. electrical market. The electrical wholesale distribution industry in the United States is large, growing and highly fragmented. Industry sources estimate total electrical wholesale distributor sales at $67.3 billion for 1997, which represents a 10.2% compound annual growth rate over 1993 sales of $45.6 billion. The four largest wholesale distributors in the United States, including WESCO, control only 14% of total industry sales. No single distributor accounts for more than 5% of industry sales, and 57% of such sales are generated by distributors with less than $21 million 27

in annual sales. In contrast, the much smaller Canadian market has achieved a high degree of concentration, with the top four distributors, including WESCO's Canadian branches, representing approximately 64% of the market. In the United States, electrical distribution is still in the early stages of consolidation, unlike many other wholesale distribution industries which have undergone substantial consolidation in the past two decades, including electronics, pharmaceuticals, laboratory and medical products, foodservice and grocery supply. WESCO, by virtue of its national and local capabilities, financial resources and focused acquisition strategy, has the opportunity to lead industry consolidation and capitalize on customer demand for value-added services and procurement outsourcing. BUSINESS STRATEGY WESCO's mission is to become the preeminent wholesale distributor of electrical and other products in each of its chosen markets by tailoring its product and service offerings to meet the differing requirements of its targeted customers. WESCO's fundamental business goal is to achieve growth in sales and profitability that is consistently above the industry average, through marketing and acquisition initiatives, leveraging its fixed cost structure and purchasing power, and improving working capital management. To achieve that goal, WESCO's business strategy emphasizes six elements: .LEVERAGE NATIONAL COORDINATION AND SCALE WESCO, with its national branch network in both the United States and Canada and the scale such network affords, has several competitive advantages: NATIONAL ACCOUNTS. WESCO offers multi-site agreements with the scope required by National Accounts--major customers such as Fortune 500 industrials and large utilities, who seek to coordinate their MRO supplies purchasing activity across multiple locations. National Accounts generated over $395 million in sales in 1997, representing a compound annual growth rate of 25% since 1995. PREFERRED SUPPLIER AGREEMENTS. WESCO enters into favorable preferred supplier agreements which provide for improved payment terms, volume rebates, marketing programs and geographic franchises. SPECIALIZED SALES FORCES. WESCO has specialized and technical sales forces to meet specific customer needs in National Accounts, data communications, automation and control, energy management, integrated supply and major construction projects. These sales forces are deployed and coordinated nationally to support marketing initiatives, program management and value- added services at the local branch level. REGIONAL DISTRIBUTION CENTERS. WESCO provides same-day shipment of a broad range of products to branches and direct to customers from five regional distribution centers, offering opportunities for economies in logistics and inventory management. .ENCOURAGE LOCAL ENTREPRENEURSHIP AND FLEXIBILITY A distributor's reputation is often determined at the local level, where timely supply and customer service are critical. Accordingly, WESCO grants its branch managers substantial autonomy in directing the branch sales force, configuring inventories, selecting markets served and developing local service options. Branches operate as separate profit and loss centers. WESCO's incentive system strongly encourages growth and profitability at the branch level, with a significant portion of the branch manager's compensation incentive based. While WESCO grants its branches a high degree of independence, they directly support and participate in national initiatives such as National Account sales, expansion of data communications product sales and marketing promotions with select manufacturers. Branches also benefit from standardized computer systems, preferred supplier agreements negotiated at the national level and a WESCO-sponsored quality initiative that has led to ISO 9002 certification for 85 branches. ISO 9002 certification is a quality measurement system based on standards set by an international federation composed of national bodies from approximately 100 countries. Almost every manufacturing, distribution and service organization is eligible to apply for ISO certification. WESCO believes it has more separately certified ISO 9002 locations than any other electrical distributor in North America. 28

.DELIVER VALUE-ADDED SERVICES WESCO offers a comprehensive portfolio of supply management services designed to create measurable value for its customers, including (1) assignment of on-site support personnel, (2) outsourcing of the entire MRO purchasing process, (3) inventory optimization programs, (4) participation in joint cost savings teams, (5) energy-efficient product upgrades, (6) safety and product training for customer employees and (7) process improvements using automation solutions. Such services are in increasing demand from industrial and utility customers seeking to improve asset utilization and reduce operating costs. In addition, WESCO is able to add accuracy and efficiency to its customer transactions by incorporating technologies such as electronic data interchange ("EDI"), electronic cataloging (such as CD-ROM and Internet ordering), on-line order entry and barcoded inventory replenishment. .FOCUS ON MARKETS WHERE WESCO HAS DEVELOPED DISTINCTIVE COMPETENCIES WESCO has developed distinctive competencies in several markets by aligning its branch network by principal market served. Business strategies, specialized personnel and locally tailored inventories are designed to match each market's requirements. WESCO targets customers with large, complex service and supply requirements in all markets where sophisticated sourcing, project management and logistical support are needed. To serve such customers effectively, WESCO leverages its national capabilities, extensive local penetration and breadth of products and services offered. In the industrial market, WESCO has created a large National Accounts organization and networks of branch managers who share best practices for automotive, pulp and paper, petrochemical, steel, mining and food processing customers. In the construction market, WESCO enjoys a strong reputation for supporting customers on larger commercial and industrial projects with design assistance, cost estimating, sourcing and project management. In the utility market, cost and competitive pressures caused by industry deregulation have created an opportunity for WESCO to provide both MRO supplies and specialized electrical transmission and distribution products to large utilities, who expect wholesalers to supply both outsourced services and the distinctive products needed for maintenance of the electrical network. Large investor-owned utilities, who have traditionally bought directly from manufacturers, are under pressure to reduce their asset base and are shifting purchases to distributors such as WESCO, who can help optimize inventory levels and reduce costs. The Company believes that it is the leading electrical wholesaler in this market. WESCO is a leading electrical wholesaler in the manufactured structures market, with a dedicated 17-branch network that provides just-in-time supply of both electrical and non-electrical products. .DRIVE CONTINUOUS IMPROVEMENT IN PRODUCTIVITY AND PROFITABILITY WESCO believes a successful business strategy must include a commitment to continuous improvement in productivity and profitability. WESCO Company is emphasizing the widespread use of innovative and disciplined approaches to managing its business processes, employee productivity and capital efficiency. These continuous improvement initiatives include (1) regular "zero based" re- evaluations of all facets of its business infrastructure, (2) activity-based costing to more accurately measure and enhance profitability by customer, supplier and other categories, (3) enhanced coordination of inventory management among suppliers, branches and regional distribution centers, (4) benchmarking, using competitive analysis and world-class best practices to set appropriate standards for expense management, working capital and employee and overall productivity, (5) increased investment in targeted areas such as sales force management and company-wide training and development and (6) application of technology to enhance information and decision support systems. .LEAD INDUSTRY CONSOLIDATION WESCO actively pursues acquisitions that complement its existing business. WESCO's acquisition strategy has been to (1) accelerate expansion into key growth markets, (2) add important new customers, (3) enhance sales of acquired branches by immediately broadening the product and service mix, (4) expand local 29

presence to better serve existing customers, (5) increase scale and breadth of relationships with manufacturers and (6) leverage existing infrastructure. WESCO considers strategic acquisitions on a continuous basis. Since August 1995, WESCO has completed 13 acquisitions with 89 branch locations and annualized sales of more than $650 million. Furthermore, as a result of these acquisitions, WESCO has added major supplier relationships with Allen-Bradley, General Electric and Square D. STRATEGY FOR CONTINUED GROWTH WESCO has increased sales by more than $1 billion since year-end 1993, a compound annual growth rate in excess of 13%. WESCO's plans for continued growth are as follows: .EXPAND PRODUCT AND SERVICE OFFERINGS WESCO intends to build on its demonstrated ability to introduce new products and services to meet customer demands and market opportunities. For example, WESCO plans to expand its presence in the data communications market. The premise wiring systems market, a product category of the total data communications market, is large and growing, with estimated 1997 U.S. sales of $2.6 billion, representing a compound annual growth rate since 1993 of approximately 14%. In the past two years, WESCO has significantly increased its focus on this market, generating sales of $83 million in 1997. Led by its dedicated data communications sales team of approximately 70 people, and leveraging its general sales force, WESCO intends to expand sales to new and existing customers, as well as broaden its offerings into other data communications product lines, such as outdoor wiring systems, active components and processors. In addition, WESCO plans to expand the number of integrated supply programs with new and existing accounts. Given the success of its integrated supply initiatives to date and the rapid growth in the demand for such services anticipated by industry sources, WESCO sees a major opportunity to develop additional customer relationships by leveraging its comprehensive service and supply expertise. .GROW NATIONAL PROGRAMS WESCO has well-established National Account relationships with approximately 300 companies. National Accounts provide ongoing revenue through strategic multi-year agreements. WESCO believes that it can expand revenue generated by its National Accounts program by (1) increasing its penetration of existing National Accounts, (2) shortening ramp-up time to full implementation, (3) adding new products to existing MRO agreements, (4) expanding agreements to include capital projects and (5) extending the program to new customers. In addition, through its Major Projects Group, WESCO plans to intensify its focus on large construction projects, such as new stadiums, industrial sites, wastewater treatment plants, airport expansions, healthcare facilities and prisons. WESCO intends to secure new contracts through (1) aggressive national marketing of WESCO's demonstrated project management capabilities, (2) further development of relationships with leading construction and engineering firms and (3) close coordination with National Account customers on their renovations and new construction projects. .GAIN SHARE IN KEY LOCAL MARKETS WESCO has identified key geographic markets with a substantial base of potential customers and will use a combination of acquisitions, new branch openings and heightened sales and marketing efforts to gain market share. WESCO's executive marketing team, together with local branch managers, will work to expand WESCO's program of detailed market analysis and opportunity identification on a branch-by-branch and product line basis. In addition, WESCO intends to leverage relationships with preferred suppliers to increase sales of their products in local markets through various initiatives including (1) sales promotions, (2) cooperative marketing efforts, (3) direct participation in National Accounts implementation, (4) dedicated sales forces and (5) product exclusivity. 30

.EXECUTE ACQUISITION STRATEGY WESCO intends to lead consolidation in the fragmented electrical wholesale distribution industry. Since adopting its acquisition strategy in August 1995, WESCO has been successful in adding more than $650 million in annualized sales, and will continue to evaluate acquisition opportunities to achieve the strategic objectives outlined under "--Business Strategy." After the Offerings, the ability, where appropriate, to use its shares to finance acquisitions should give WESCO access to an expanded range of possible acquisitions. WESCO seeks acquisitions that will be accretive to earnings and will significantly complement the organic growth of the business. The 13 acquisitions completed by WESCO to date have collectively been accretive to its earnings. . ACCESS INTERNATIONAL OPPORTUNITIES WESCO believes in a pragmatic and profitable expansion of sales outside the United States and Canada. WESCO intends to limit risk and maximize profit opportunities, principally by following its National Account customers and key suppliers into their non-U.S. markets. For example, WESCO has opened a branch in Mexico City, where many current customers have plant operations and where WESCO has been granted the highly regarded Allen-Bradley franchise. Other opportunities to grow international sales include expanding the network of independent export sales representatives outside of North America, increasing the number of North American-based export sales offices and building closer relationships with global engineering, procurement and constructions firms. 31

ACQUISITIONS In mid-1995 WESCO launched its program to make acquisitions that complement its existing business. See "--Business Strategy." Since August 1995, WESCO has completed 13 acquisitions, with 89 branch locations and annualized sales of over $650 million. These acquisitions and the key rationale for each are summarized below. NUMBER OF ANNUAL YEAR COMPANY HEADQUARTERS BRANCHES SALES (1) KEY RATIONALE ---- ------------------------ ---------------- -------- ---------- -------------------------------------------------- (MILLIONS) 1995 Fife Electric Detroit, MI 1 $ 42 Capitalized on strong relationships with auto manufacturers and introduced Square D franchise.

The largest acquisition completed to date was EESCO, Inc. ("EESCO"), the eighth largest electrical wholesale distributor in the United States at the time it was acquired by WESCO in April 1996. As a result of the EESCO acquisition, WESCO increased coverage in the key Chicago and Minneapolis markets, developed important new supplier relationships (Allen-Bradley and General Electric), increased scale and realized cost savings through the consolidation of branches and the reduction of selling, general and administrative expenses. WESCO has substantially increased the sales and profitability of EESCO by (1) increasing investment capital for new and existing EESCO branches, (2) expanding EESCO's technical support group and (3) including EESCO branches in National Account programs and preferred supplier agreements. Since its acquisition, EESCO's annual net sales have increased to $341 million for 1997 from $288 million for 1995. In January 1998, WESCO acquired the electrical distribution businesses of Avon Electrical Supplies, Inc., and its affiliates ("Avon Electrical") and Brown Wholesale Electric Company ("Brown Wholesale"). Avon Electrical, operating at two branch locations, is a leading distributor in the New York metropolitan area. Brown Wholesale operates from seven branch locations in California and Hawaii and two in Arizona, where it is the leader in the high- growth Phoenix market. These acquisitions will add approximately $150 million in annualized 32

sales. WESCO funded the aggregate purchase price of approximately $59.5 million through $45.0 million in borrowings under its existing credit facilities, and issuing $14.5 million aggregate principal amount of its unsecured notes, maturing by mid-1999. Up to $5 million of such notes may be converted to shares of Class A Common Stock at the initial public offering price at the election of the holder, which election is required to be made prior to the Offerings. In connection with the Avon Electrical acquisition, two principals of the seller purchased an aggregate 1,992 shares of Class A Common Stock at a purchase price of $250.97 per share. PRODUCTS AND SERVICES WESCO's network of branches and distribution centers contains approximately 210,000 unique product stock keeping units ("SKUs"), and the average branch routinely maintains in its warehouse stock approximately 4,000 to 8,000 SKUs. The six major product groups currently distributed are (1) supplies, including fuses, terminals, connectors, boxes, fittings, tools, lugs and tapes, (2) distribution equipment, including circuit breakers, transformers, switchboards, panelboards and busway, (3) lighting, including lamps, fixtures and ballasts, (4) wire and conduit, including wire, cable, steel conduit and PVC conduit, (5) control, automation and motors, including motor control centers, drives, programmable logic controllers, pushbuttons and operator interfaces, and (6) data communications, including premise wiring, patch panels, terminals, connectors, hubs and routers. WESCO's sales mix by product group for 1997 was as follows: PRODUCT PERCENT OF 1997 SALES ------- --------------------- Supplies............................................ 25% Distribution Equipment.............................. 23 Wire & Conduit...................................... 22 Lighting............................................ 19 Control, Automation & Motors........................ 8 Data Communications................................. 3 In conjunction with product sales, WESCO offers customers a menu of services and procurement solutions that draws on its product and supply management expertise and systems capabilities. These services range from multi-site National Account programs to on-site integrated supply. NATIONAL ACCOUNTS. WESCO's national platform, strong branch network and product breadth give it the capacity to offer multi-site agreements with the scope required by National Accounts--major customers such as Fortune 500 industrials and large utilities. The typical National Account customer seeks total supply chain cost reductions by coordinating purchasing activity for MRO supplies across multiple locations. Through rigorous selection processes, these customers dramatically reduce their electrical supply base--often from several hundred suppliers to just one--with expectations for measurable cost reductions, high levels of service and consistent product and pricing across all locations. As a result of its implementation processes, WESCO is able to consistently document double-digit savings within the first year of program launch. Comprehensive roll-out plans establish jointly-managed implementation teams at the local and national level to prioritize activities, track progress against objectives, and identify key performance measures. WESCO is increasingly involving its preferred suppliers early in the implementation process, where they can contribute expertise and product knowledge to accelerate program ramp-up and the capture of savings. In the first year of its relationship with a 17-location National Account customer in the pulp and paper industry, for example, WESCO documented savings of more than 17% over 12 savings categories, including unit price reductions, inventory reductions, energy savings and application engineering. In another instance, WESCO's sales to a National Account customer in the petrochemical industry have grown steadily from $4.4 million in 1994 to $14 million in 1997. WESCO documented total cost savings of $1.4 million as a result of its initiatives at the customer's ten major refineries. During 1997, WESCO delivered 33

additional savings through a variety of continuous improvement initiatives, including remote electronic updates of contract pricing in the customer's computer system and product standardization for high-volume commodities. WESCO's performance has led to international supply opportunities with this customer. INTEGRATED SUPPLY PROGRAMS. WESCO's integrated supply programs offer customers a variety of services to support their objectives for improved supply chain management. WESCO integrates its personnel, product and distribution expertise, electronic technologies and service capabilities with the customer's own internal resources to meet particular service requirements. Each integrated supply program is uniquely configured to deliver a significant reduction in the number of MRO suppliers, reduce total procurement costs, improve operating controls and lower administrative expenses. WESCO can act as the customer's "integrator," responsible for selecting and managing suppliers of a wide range of MRO and OEM products. WESCO may also develop a customer's integrated supply program in collaboration with one or more distributors of complementary product lines. Major national distributors have joined with WESCO in both formal and informal "alliances" to generate cross-sales opportunities, share market expertise and execute integrated supply agreements. In one case, a petrochemical customer directed WESCO, which was already furnishing electrical and related supplies to its West Coast refinery, to work with a safety distributor and a pipe, valve, and fitting distributor to jointly design and operate an "integrated supply warehouse." Three on-site specialists, one from each company, now manage the customer's inventory, make daily deliveries to over 100 use points, and replenish parts bins throughout the refinery. ELECTRONIC COMMERCE. WESCO enhances its ability to service customers accurately and efficiently by incorporating technologies such as EDI, electronic mail, electronic cataloging (such as CD-ROM and Internet ordering), direct order entry and barcoded bin labelling to streamline inventory replenishment. WESCO also employs technological and logistical innovations in its internal operating processes to improve customer service, including paperless warehousing, cross-docking, barcoding and automatic stock replenishment. SUPPLIERS AND PURCHASING WESCO's supplier relationships are strategically important to WESCO, providing access to a wide range of products, technical training and sales and marketing support. Manufacturers often take an active role in marketing products to the customer by deploying their own sales force and/or independent manufacturers' representatives to work together with wholesalers. WESCO's rapid growth, size, geographic scope and marketing initiatives with large, high profile customers make it an attractive partner for manufacturers. As a result, WESCO has been able to negotiate broad access to most product lines, including preferred arrangements with regard to volume discounts, payment terms, marketing support and logistics. WESCO purchases products from a diverse group of over 6,000 suppliers. Through December 31, 1997, ten suppliers accounted for 45% of the Company's purchases, with 200 suppliers accounting for 85% of purchases. The largest of these was Eaton Corporation, through its Cutler-Hammer division, successor to the Distribution and Control Business Unit of Westinghouse, accounting for 18% of total purchases. No other supplier accounted for more than 2%. WESCO's ten largest suppliers, based on 1997 purchases through December 31, 1997, and their principal product lines are as follows: SUPPLIER PRODUCT LINE -------- ------------------------ Cutler-Hammer Distribution and Control Allen-Bradley Control and Automation Asea Brown Boveri Transformers Philips Lighting Lamps Southwire Company Wire and Cable Cooper Lighting Lighting Fixtures Thomas & Betts Supplies Lithonia Lighting Lighting Fixtures Crouse Hinds Fittings General Electric Lamps 34

WESCO has preferred supplier agreements with approximately 150 of its suppliers, and purchases approximately 60% of its stock inventories from suppliers pursuant to these agreements. Consistent with industry practice, most of WESCO's agreements with suppliers, including both distribution agreements and preferred supplier agreements, are terminable by either party on no more than 60 days notice. See "Risk Factors--Key Suppliers; Maintenance of Supply; Interruption of Distribution Center Operations." In order to capitalize on its buying power as a national network, WESCO has increasingly centralized buying by moving a larger proportion of branch stock through its five regional distribution centers. To preserve local flexibility in tailoring their inventories to meet local customer requirements, branches are offered the option of purchasing a choice of competing lines from the distribution centers. WESCO has a product management group to manage key supplier relationships, including negotiating preferred supplier agreements, managing cooperative marketing funds, organizing product training, developing joint marketing plans with suppliers, evaluating supplier performance and driving continuous improvement programs. MARKETS AND CUSTOMERS WESCO has a large customer base diversified across its principal markets, and maintains current credit files on approximately 130,000 accounts. With no customer accounting for more than 2% of sales, WESCO is not dependent on any single customer. WESCO's broad customer base includes (1) industrial companies from numerous manufacturing and process industries, and OEMs, including manufacturers of factory-built homes and other modular structures, (2) contractors for industrial, commercial and residential projects, (3) investor- owned utilities, municipal power authorities and rural electric cooperatives and (4) commercial, institutional and governmental ("CIG") customers. INDUSTRIAL--MRO CUSTOMERS. Sales to industrial MRO customers accounted for approximately 16% of the electrical wholesale market and, together with original equipment manufacturers, 40% of the Company's sales in 1997. Electrical products are needed to maintain and upgrade the electrical network at all industrial sites. Expenditures are greatest in the heavy process industries, such as pulp and paper and petrochemical. Typically, electrical MRO is the first or second ranked product category by purchase value for MRO. Other MRO product categories might also include, among other things, lubricants; pipe, valves and fittings; fasteners; and power transmission products. MRO activity has been difficult for industrial users to manage, as it is characterized by a fragmented supply base, a high volume of low dollar transactions, poor usage and cost information and relatively high inventory levels. For example, it would not be unusual for a customer to inventory as many as 10,000 MRO SKUs. Furthermore, customers are sensitive to supply reliability, since a lack of critical spares could cause an entire manufacturing process to shut down. WESCO is responding aggressively to the needs of this market, particularly for the high-use customers in heavy process industries. To more efficiently manage the MRO process on behalf of its customers, WESCO offers a menu of supply management services, including (1) inventory optimization programs, such as product standardization and substitution, (2) joint cost savings teams, (3) outsourcing of the entire MRO purchasing process, (4) energy- efficient product upgrades, (5) product and safety training for customer employees and (6) assignment of on-site support personnel. WESCO's most distinctive service is its National Accounts program, with the ability to offer multi-site agreements to large industrial customers to ensure local supply with nationwide consistency in product and pricing. INDUSTRIAL--OEM CUSTOMERS. Sales to industrial OEM customers accounted for approximately 9% of the electrical wholesale market in 1997. These customers incorporate electrical assemblies and components into their own products and typically require a reliable, high-volume supply of a narrow range of electrical items. The wholesale channel generally serves the smaller and medium-sized OEMs, while the larger OEMs typically purchase directly from manufacturers. Customers in this segment are price and service sensitive due to the 35

volume and the critical nature of the product used. OEMs also expect value- added services such as design and technical support, just-in-time supply and electronic commerce. While prices tend to be lower in this market due to usage volume, long-term relationships are typical, which leads to an efficient supply process and stable, high volume. WESCO addresses this market by (1) providing experienced, technically- oriented sales specialists who assist in product specification and selection, prototype development and supplier coordination, (2) offering supply management services similar to those provided to industrial MRO customers, (3) securing access to product lines that are commonly specified by OEMs, (4) working with suppliers on product application development and (5) offering specialized packaging or kitting services that bring efficiencies to the customer's manufacturing process. WESCO is the leading electrical wholesaler in the manufactured structures market, a particular type of OEM. For the past several years WESCO has been expanding its service to these customers by offering non-electrical products such as structural components, air conditioning units, plumbing fixtures, cabinets and kitchen ventilation equipment. ELECTRICAL CONTRACTORS. Sales to electrical contractors accounted for approximately 40% of the electrical wholesale market and approximately 38% of WESCO's sales in 1997. These customers range from large contractors for major industrial and commercial projects, the customer types which WESCO principally serves, to small residential contractors who represent a small portion of WESCO's sales. Electrical products purchased by contractors typically account for approximately 40% to 50% of the total installed cost, and therefore accurate cost estimates and competitive material costs are critical to a contractor's success in winning projects at a profit. Contractors choose wholesale suppliers on the basis of price, availability and various support services such as design assistance, bill of material development, credit policies and inventory management. WESCO is one of the industry leaders in serving the complex needs of large commercial and industrial contractors, and has established a Major Projects Group to focus some of its most experienced personnel on serving the needs of the top 50 U.S. electrical contractors on a multi-regional basis. WESCO also offers a comprehensive range of services to meet the needs of contractors, including commodity blanket purchase agreements, on-line ordering, CD-ROM catalogs, on-site trailers, lighting and distribution equipment lay-outs and access to low voltage products, especially data communications. WESCO has also worked to strengthen its relationships with independent manufacturers' representatives who provide additional sales coverage, technical assistance and training on behalf of manufacturers. UTILITIES. Sales to utilities accounted for approximately 4% of the electrical wholesale market and approximately 14% of WESCO's sales in 1997. These customers include large investor-owned utilities, smaller rural electric cooperatives and municipal power authorities. Traditionally, investor-owned utilities have purchased product directly from manufacturers, while smaller rural electric cooperatives and municipal power authorities have been supplied by electrical wholesalers, including WESCO. Both large and small utility customers require relatively high dollar volumes of specialized product to maintain the electrical network. Access to these specialized utility products is limited by geographic franchises granted by manufacturers. These products are, therefore, not generally available to all electrical wholesalers at the pricing required by utility customers. Recent trends in the utility industry favor utility-oriented electrical wholesalers, such as WESCO. The Company believes that it is the leading electrical wholesaler to this market, with approximately a 13% share. The most important trend is the deregulation of utility power generation, which has forced large utilities to seek better asset utilization and cost savings in all aspects of their operations, including purchasing and supply management. Investor-owned utilities, in focusing on their core business, have moved to outsource certain supply functions to wholesalers in order to reduce costs and enhance cash flow. For example, WESCO has been selected for supply management agreements with ComEd, PECO Energy and Wisconsin Electric Power Company. These agreements generally have terms of 2 to 3 years and an annual contract value of $2 million to $10 million. COMMERCIAL, INSTITUTIONAL AND GOVERNMENTAL CUSTOMERS. Sales to CIG customers accounted for approximately 21% of the electrical wholesale market and approximately 7% of WESCO's sales in 1997. This is a fragmented market which includes schools, hospitals, property management firms, retailers (not for resale) and government agencies of all types. These customers typically have less complex product and service needs than 36

large contractors or industrial and utility customers. WESCO's locally oriented and entrepreneurial branch operations are well positioned to serve these customers. WESCO's National Accounts strategy also extends to multi-site financial institutions, department stores and amusement parks. National retail or service chains tend to favor distributors such as WESCO who can meet their recurring needs at dozens or hundreds of store or office locations. OTHER ELECTRICAL CUSTOMERS. Sales to other electrical customers accounted for approximately 10% of the electrical wholesale market and less than 1% of WESCO's sales in 1997. These customers include the general public, retailers (for resale), farmers and other wholesalers. DATA COMMUNICATIONS CUSTOMERS. The growing market for data communications products includes (1) all aspects of facilities and premise wiring for data networks and (2) electronic devices and processors that transmit and manage the data flowing through a network. Because of the convergence of voice, data, and video applications, the data communications market consists of a wide range of new products and manufacturers that are not included in the estimates for the electrical industry. The premise wiring component of the data communications market is estimated by industry sources to grow to approximately $5 billion in total sales by the year 2001, with as much as $3 billion of this sales potential falling outside the usual projections for the electrical industry. DISTRIBUTION NETWORK BRANCH NETWORK. WESCO operates a system of approximately 330 branches, of which approximately 275 are located in the United States, approximately 50 are located in Canada and the remainder are located in Puerto Rico, Mexico and Guam. WESCO also has sales offices in four other international locations and operates a network of branches under management contract in Saudi Arabia. Approximately 30% of branches are owned facilities, and the remainder leased facilities. WESCO's branches were initially opened in markets with a minimum population of 50,000 or in close proximity to major customers. Over the last two years WESCO has opened approximately 15 branches per year, principally to service National Account customers. The size of individual branches within WESCO's nationwide network varies broadly. In 1997, WESCO's branches had annual sales as high as $66 million, with an average of approximately $8 million. A representative branch employs 10 to 15 people and typically stocks a product mix of 4,000 to 8,000 SKUs, tailored to its local customer base. Customers can place orders at the branches through facsimile, telephone, mail, EDI, on-line order entry or counter appearances. WESCO grants its branch managers substantial autonomy in directing the branch sales force, configuring inventories, selecting markets served and developing local service options. Branches operate as separate profit and loss centers. A key aspect of WESCO's growth strategy is to encourage higher levels of productivity by creating appropriate economic incentives for branch managers through a mix of bonuses and stock options tied to the branch's growth and profit improvement. Since the Acquisition and the implementation of this incentive system, WESCO's average compensation for branch managers has increased by approximately 60%. See "Management--Stock Option Plan for Branch Employees." DISTRIBUTION CENTERS. To support its branch network, WESCO has a system of five regional distribution centers ("DCs") which supply approximately 20% of total purchases (45% of stock purchases). The following is a summary description of the DCs: LOCATION SQUARE FEET REGIONS SERVED LEASED/OWNED -------- ----------- -------------------------- ---------------- Warrendale, PA 252,699 Eastern United States Owned and Leased Sparks, NV 195,800 Western United States Leased Byhalia, MS 148,000 Southeastern United States Owned Dorval, QE 97,000 Eastern and Central Canada Leased Burnaby, BC 34,341 Western Canada Owned 37

The DCs add value to customers in the following ways: (1) shorter lead times for product supply; (2) better product availability due to the breadth and depth of stock; (3) same day shipments for orders received up to 8:30 p.m.; and (4) central order handling and fulfillment for certain multi-site customers. In addition to creating value for customers, the DCs improve WESCO's supply chain management through: (1) automatic replenishment of branch stock; (2) on-line ordering for branches; (3) redeployment of slow-moving branch stock; (4) automation of branch purchasing administration; (5) bulk purchasing to achieve order discounts; and (6) advanced distribution techniques such as paperless picking, flow racking, barcoding, weight verification, electronic freight management and cross-docking. Suppliers also benefit from the DCs due to larger order sizes and lower transportation costs. DCs ship to branches every day, for same-day orders or orders previously generated through WESCO's computerized automated stock replenishment system. TRANSPORTATION AND LOGISTICS. WESCO offers its customers a variety of delivery methods, including: (1) direct shipment from the manufacturer, which is employed for many large orders and engineered products; (2) branch shipment, which is used for the large majority of stock and special order sales; (3) branch pick-up, which is used by some customers, particularly contractors, for their day-to-day business; and (4) shipment from a DC on an exception or emergency basis, since DCs are primarily used to replenish branch stock. Typically, manufacturers pay freight charges for inbound shipments to DCs, branches or customers. In some instances, prepaid freight terms are contingent upon WESCO meeting certain minimum order requirements. For some suppliers and where it results in lower overall transportation costs, WESCO has negotiated pick-up allowances in lieu of prepaid freight. SALES ORGANIZATION GENERAL SALES FORCE. WESCO's general sales force is based at the local branches, and comprises approximately 2,000 sales personnel, split equally between outside sales representatives and inside sales personnel. Outside sales representatives, who have an average of more than eight years of experience at WESCO, are paid under a compensation structure which is heavily weighted towards commissions. They are responsible for making direct customer calls, performing on-site technical support, generating new customer relations and developing existing territories. The inside sales force is the support organization for the outside sales force and is a key point of contact for responding to routine customer inquiries such as price and availability requests and for entering and tracking orders. NATIONAL ACCOUNTS. WESCO has what management believes to be the largest National Account sales force in the industry, led by an experienced group of sales executives who negotiate and administer contracts, coordinate branch participation, identify sales and service opportunities. National Accounts managers' efforts are aligned by targeted customer industries, including automotive, pulp and paper, petrochemical, steel, mining and food processing. DATA COMMUNICATIONS. Data communications products are supported by a dedicated sales force of approximately 70 inside and outside representatives who focus primarily on the premise wiring systems market. This team is supported by additional resources in purchasing, inventory management, product training, product management and regional sales management. WESCO also operates a training facility where customers and the general sales force can receive industry-recognized certification in product installation. INDUSTRIAL AUTOMATION SPECIALISTS. According to industry estimates, sales of automation and control products are growing faster than the overall industry average as technology advances and industrial firms of all types seek more productive processes. The service hallmark of WESCO's EESCO Division is its specialization in automation and control products. Its general sales staff is highly trained in assisting customers with process control applications, and a separate staff of 58 technical support and automation specialists provides sales assistance for analysis, design, specification and implementation. In addition, other WESCO branches which primarily serve industrial MRO and OEM customers draw on a dedicated staff of technically trained industrial automation specialists, who are strategically located in selected high- potential market areas and provide support and assistance to multiple branches. Overall, a total of approximately 90 automation and control specialists are currently employed throughout WESCO. 38

MAJOR PROJECTS GROUP. In 1995, WESCO established a group of highly experienced sales managers to target, on a national basis, the market for large construction projects with electrical material valued in excess of $1 million. WESCO's approach distinguishes it from almost all of its competitors, who typically handle even the largest construction projects on a local basis. Through the Major Projects organization, WESCO can meet the needs of contractors for complex construction projects such as new stadiums, industrial sites, wastewater treatment plants, airport expansions, healthcare facilities and prisons. CANADA To serve the Canadian market, WESCO operates a network of approximately 50 branches in nine provinces. Branch operations are supported by two distribution centers located near Montreal and Vancouver. With sales of approximately US$280 million, Canada represented 11% of total WESCO sales in 1997. The Canadian market for electrical wholesale is considerably smaller than the U.S. market, with roughly US$2.4 billion in total sales according to industry sources. The Canadian market is also far more concentrated than the U.S. market, based on estimated market data, with Westburne (33% share), Guillevin, owned by Consolidated Electrical Distributors (12% share), WESCO's Canadian branches (11% share) and Sonepar (8% share) collectively representing approximately 64% of the market, compared to approximately 14% for the top four U.S. wholesalers. WESCO's Canadian operations have a strong reputation for serving the needs of medium and large contractors, which in 1997 represented 61% of WESCO's Canadian sales. More recently, WESCO has been successful in growing sales with industrial customers, through marketing of control products and the development and expansion of instrumentation product sales. National Account programs are also being successfully applied to this market, building on WESCO's U.S. experience with industrial customers. Data communications product sales have grown rapidly in Canada from a negligible amount in 1993 to approximately 8% of total Canadian sales in 1997. INTERNATIONAL WESCO is continuing to build its international presence outside of the United States and Canada, principally by following its National Account customers and key suppliers into their high-growth markets, thereby limiting start-up risk and maximizing profit opportunity. Other opportunities to grow international sales include expanding and improving the quality of the network of independent export sales representatives outside of North America, increasing the number of North American-based export sales offices and building closer relationships with global engineering, procurement and construction firms. With sales of approximately US$64 million, international sales (excluding Canada) represented 2% of total WESCO sales in 1997. WESCO channels its international sales principally through 13 sales offices, six of which are located within North America (export offices) and seven of which are in international locations, and through sales representatives in 22 foreign countries. WESCO plans to open additional branches in the Mexico City area, where WESCO has the highly regarded Allen-Bradley franchise for the Federal District and three surrounding states. WESCO estimates that the Mexico City market area represents 40% of total purchases in the $1.5 to $2.0 billion Mexican market. A sales contact database of the foreign locations of WESCO's National Account customers is under development. It is estimated that over 1,000 plant sites outside of North America will eventually be covered by a direct sales and telemarketing program. MANAGEMENT INFORMATION SYSTEMS WESCO's corporate information system, WESCOM, provides low-cost, highly functional processing of business transactions. WESCOM performs services necessary to support the full range of business operations, such as customer service, inventory and logistics management, accounting and administrative support. The system has been upgraded with decision support, executive information system analysis and retrieval capabilities to provide detailed income statement and balance sheet variance and trend reporting at the branch level. The 39

system also provides activity based costing capabilities for analyzing profitability by customer, supplier, sales representative and shipment type. Sales and margin trends and variances can be easily analyzed by branch, customer, product category, supplier, or account representative. The WESCOM system is fully distributed, so every branch (other than EESCO branches, which are in the preliminary stages of being integrated) has its own computer system to support local business activities, on a real time basis, from sales quotation to delivery of products to customers. Telecommunication links through a central system in Pittsburgh give each branch access to information on inventory status in WESCO's distribution centers as well as other branches and an increasing number of on-line suppliers. WESCO conducts a portion of its business through EDI transactions, typically exchanging in excess of 65,000 EDI transactions per month with its trading partners. WESCO's electronic commerce strategy calls for tighter linkages to both customers and suppliers through greater use of technological advances, including Internet and CD-ROM catalogs, barcoding, enhanced EDI, electronic funds transfer and other innovative improvements. WESCO is in the process of modifying, upgrading or replacing its computer software applications and systems to accommodate the "Year 2000" changes required for correct recording of dates for the year 2000 and beyond. WESCO does not expect that the cost of its Year 2000 compliance program will be material to its financial condition or results of operations. WESCO believes that it will be able to achieve compliance by the end of 1999, and does not currently anticipate any material disruption in its operations. WESCO does not currently have any information concerning the compliance status of its suppliers and customers. In the event that any of WESCO's significant suppliers or customers do not successfully achieve Year 2000 compliance, WESCO's business or operations could be adversely affected. BACKLOG WESCO measures and monitors backlog for large construction project orders by reassessing the status of all direct shipment orders at the end of each month. The vast majority of backlog orders will ship within one year. At December 31, 1997, such backlog orders were approximately $309 million as compared to $287 million at December 31, 1996, representing an increase of $22 million, or 8%. Since backlog orders reflect varying ship dates based on customer needs or production schedules, WESCO does not believe changes in the backlog necessarily correlate to the level of future monthly sales. In addition, backlog orders at December 31, 1996 do not reflect backlog orders of branches acquired since that date. COMPETITION The electrical wholesale distribution market is highly fragmented and competitive. In the United States, there are currently an estimated 8,000 electrical wholesale distributors with over 16,000 outlets. The four largest distributors, including WESCO, control only 14% of total industry sales. No single distributor accounts for more than 5% of industry sales, and approximately 57% of such sales are generated by distributors with less than $21 million in annual sales. In contrast, the top four distributors in Canada account for 64% of the market. See "Risk Factors--Competition." WESCO competes directly with national, regional and local distributors. Certain large competitors, distributors such as Graybar Electric Company, Inc., Consolidated Electrical Distributors and GE Supply Company, compete nationally, and offer a broad base of products. Large regional companies in the United States and Canada, such as Rexel, Inc., Crescent Electric Supply Company, Cameron & Barkley Company, Platt Electric Supply Inc., Sonepar and Westburne Inc., are strong competitors within their regions. Certain other competitors, such as W.W. Grainger Inc., which focuses primarily on industrial supplies distribution, overlap with electrical wholesale distributors in some product lines. Distinct from these full-line distributors are niche distributors that carry only certain products such as wire, lighting products, or data communications equipment. Competition among electrical wholesale distributors is primarily focused on the local service area, and is generally based on product line breadth, product availability and price. WESCO believes that it has certain 40

competitive advantages over certain of its local competitors, which are not able to carry the range of products stocked by WESCO or achieve purchasing economies of scale. However, some of WESCO's competitors are larger and have access to greater financial and marketing resources than WESCO. Another source of competition is buying groups formed by smaller distributors to increase purchasing power and provide some limited cooperative marketing capability. The two largest of these are Affiliated Distributors, representing an estimated $5 billion of annual electrical wholesale distribution sales, and IMARK, representing an estimated $3 billion of annual sales, based on industry sources. While increased buying power may improve the competitive position of buying groups locally, WESCO does not believe these groups have been able to compete effectively with WESCO for National Account customers due to the difficulty in coordinating a diverse ownership group. Outside of the wholesale distribution channel, manufacturers employ, and may increase the use of, direct sales and/or independent manufacturers representatives. Some manufacturers with sufficient size, geographic scope and financial and marketing resources may be in a position to offer customers National Account services. Consumer channels such as hardware stores, DIY retail outlets (such as Home Depot), mass merchants and grocery stores also compete for certain customers. Some retail chains, with nationwide purchasing advantages, can in certain product categories offer prices comparable to those of the wholesale distributors, although with a much narrower product offering overall. These channels attract smaller residential contractors who work on projects generally requiring basic electrical supplies. Such contractors represent a small portion of WESCO's sales. WESCO's customers typically require a broader range of products and services than those provided by these retail channels. EMPLOYEES As of December 31, 1997, WESCO had approximately 4,700 employees worldwide, of which approximately 4,000 are located in the United States and approximately 700 in Canada and WESCO's other foreign locations. Less than 5% of WESCO's employees are represented by unions. WESCO believes its labor relations to be generally good. PROPERTIES In addition to its five regional distribution centers, WESCO leases its 60,389 square foot headquarters in Pittsburgh, Pennsylvania. For a description of the distribution centers, see "--Distribution Network--Distribution Centers." WESCO does not regard the real property associated with any single branch location as material to its operations. WESCO believes its facilities are in good operating condition. WESCO's owned real property, including its three owned distribution centers, serves as collateral for certain mortgage notes issued to Westinghouse in connection with the Acquisition. See "Description of Certain Indebtedness--Mortgage Notes." INTELLECTUAL PROPERTY WESCO's trade and service mark, composed of the words "WESCO the extra effort people(R)," together with the running man design, is registered in the United States Patent and Trademark Office, the Canadian Trademark Office and the Mexican Instituto de la Propriedad Industrial. WESCO considers this mark to be material to its businesses. ENVIRONMENTAL MATTERS WESCO believes that it is in substantial compliance with applicable Environmental Laws. There are no significant capital expenditures for environmental control matters either estimated in the current year or expected in the near future. See "Risk Factors--Environmental Risks." LEGAL PROCEEDINGS WESCO is party to routine litigation incidental to WESCO's business. WESCO does not believe that any legal proceedings to which it is a party or to which any of its property is subject, will have a material adverse effect on WESCO's financial position or results of operations. 41

COMPOSITION OF BOARD AND COMMITTEES The Board of Directors of CDW and WESCO (the "Board") has three standing committees: an Executive Committee, an Audit Committee and a Compensation Committee.

It is responsible for overseeing the management of the affairs and business of the Company and has been delegated authority to exercise the powers of the Board during intervals between Board meetings. The Audit Committee consists of Messrs. Barbe, Caldwell, Hendrix and Walker, with Mr. Caldwell serving as Chairman. It is responsible for recommending the firm to be appointed as independent accountants to audit the Company's financial statements and to perform services related to the audit; reviewing the scope and results of the audit with the independent accountants; reviewing with the management and the independent accountants the Company's year-end operating results; considering the adequacy of the internal accounting and control procedures of the Company; reviewing the non-audit services to be performed by the independent accountants, if any, and considering the effect of such performance on the accountants' independence.

It is responsible for the review, recommendation and approval of compensation arrangements for directors and executive officers, for the approval of such arrangements for other senior level employees, and for the administration of certain benefit and compensation plans and arrangements of the Company. COMPENSATION OF DIRECTORS CDW's policy is not to pay compensation to those directors who are also employees of CDW or any of its subsidiaries or affiliated with CD&R or any principal stockholder of CDW. All directors are, however, reimbursed for expenses incurred in attending Board and committee meetings. The non-employee directors of the Company who are not affiliated with CD&R or any principal stockholder of CDW receive an annual retainer of $20,000 and additional fees of $1,000 per meeting for attendance at Board meetings and $500 per meeting for attendance at committee meetings.

EMPLOYMENT AGREEMENTS In connection with WESCO's acquisition of EESCO, WESCO entered into an employment agreement with Mr. Weiss (the "Weiss Agreement"), pursuant to which WESCO agreed to employ Mr. Weiss during the period commencing on the date of the acquisition and ending on December 31, 1998, subject to WESCO's right to terminate Mr. Weiss' employment prior to such date for "cause" (as defined in the Weiss Agreement) without any continuing liability. During the employment term under the Weiss Agreement, Mr. Weiss is entitled to an annual base salary of $300,000 and, provided WESCO attains annual performance objectives established from year to year by WESCO, an annual incentive bonus equal to a percentage of his annual base salary, not to exceed 75%. In the event of the termination of Mr. Weiss' employment with WESCO by Mr. Weiss for "good reason" (as defined in the Weiss Agreement), Mr. Weiss will continue to receive payments of his annual base salary for the remainder of the employment term. The Weiss Agreement also contains customary covenants regarding nondisclosure of confidential information and non-competition and non-solicitation restrictions. WESCO intends to enter into an employment agreement with Mr. Haley (the "Haley Agreement") providing for a rolling employment term of three years. Pursuant to the proposed Haley Agreement, Mr. Haley will be entitled to an annual base salary of $500,000 and an annual incentive bonus equal to a percentage of his annual base salary ranging from 0% to 200%. The actual amount of Mr. Haley's annual incentive bonus will be determined based upon the financial performance of WESCO as compared to the annual performance objectives established by CDW for the relevant fiscal year. Under the proposed terms of the Haley Agreement, if Mr. Haley's employment with CDW and WESCO is terminated by CDW and WESCO without "cause" (as defined in the Haley Agreement), by Mr. Haley for "good reason" (as so defined) or as a result of Mr. Haley's death or disability (any such termination, a "Qualifying Termination"), Mr. Haley (or, in the event of his death, 46

Mr. Haley's spouse) is entitled to continued payments of his average annual base salary and his average annual incentive bonus (reduced by any disability payments, if applicable) for the three-year period, or in the case of a termination due to Mr. Haley's death or disability, the two-year period, following such termination, and continued welfare benefit coverage for the two-year period following such termination. In addition, in the event of any such Qualifying Termination, all outstanding options held by Mr. Haley will become fully vested. The Haley Agreement further provides that, in the event of the termination of Mr. Haley's employment by CDW and WESCO without cause or by Mr. Haley for good reason, in either such case, within the two-year period following a "change in control" of CDW or WESCO (as defined in such agreement) (such termination, a "Qualifying CIC Termination"), in addition to the termination benefits described above, Mr. Haley will be entitled to receive continued welfare benefit coverage and payments in lieu of additional contributions to WESCO's Retirement Savings Plan and Deferred Compensation Plan for the three year period following such Qualifying CIC Termination, provided that if the aggregate payments to Mr. Haley would exceed the limits on the deductibility of certain parachute payments under the United States Internal Revenue Code of 1986, as amended, such payments will be reduced as necessary to ensure deductibility. In addition, following a change in control, Mr. Haley is entitled to a minimum annual bonus equal to 50% of his base salary and the definition of "good reason" is modified to include certain additional events. The proposed Haley Agreement also contains customary covenants regarding nondisclosure of confidential information and non- competition and non-solicitation restrictions. CDW and WESCO also intend to enter in an employment agreement with David McAnally (the "McAnally Agreement"), the Executive Vice President, Chief Operating Officer and Chief Financial Officer of WESCO and Treasurer of each of CDW and WESCO, providing for an employment term of two years, subject to automatic renewal at the end of each year for an additional year. Pursuant to the proposed terms of the McAnally Agreement, Mr. McAnally will be entitled to an annual base salary of $300,000 and, depending upon the extent, if any, to which WESCO achieves the performance objectives established for an applicable fiscal year, an annual incentive bonus ranging from 0 to 100% of his annual base salary; provided that Mr. McAnally is entitled to a minimum annual bonus for 1998 of $150,000. In addition, under the proposed terms of the McAnally Agreement, Mr. McAnally will purchase up to 2,500 shares of Class A Common Stock at the initial public offering price and, pursuant to the existing Stock Option Plan, will be granted options to purchase 17,500 shares of Class A Common Stock at an option exercise price per share equal to the initial public offering price. The options generally become vested in five equal annual installments on each of the first five anniversaries thereof subject to Mr. McAnally's continued employment. See "--Long-Term Incentive Plan." The proposed terms of the McAnally Agreement provide that in the event of a Qualifying Termination of Mr. McAnally's employment, Mr. McAnally (or, in the event of his death, his spouse) will be entitled to continued payments of his average annual base salary and average annual incentive bonus (reduced by any disability payments, if applicable) and to continued welfare benefit coverage, in each such case, for a period ending on the later of (1) the date of the expiration of the then current employment term and (2) the first anniversary of the date of such Qualifying Termination, provided that if such Qualifying Termination occurs prior to the second anniversary of Mr. McAnally's commencement of employment with WESCO, such payments and benefit coverage will be provided for a period of one year following such termination. In addition, in the event of a Qualifying Termination of Mr. McAnally's employment following the second anniversary of the commencement of his employment, 50% of any outstanding options granted to Mr. McAnally will become vested. It is expected that the McAnally Agreement will contain provisions similar to the provisions of the Haley Agreement concerning a "change in control" of CDW or WESCO, except that in the event of a Qualifying CIC Termination, Mr. McAnally will be entitled to continued payments of his average annual base salary and average bonus and continued welfare benefit coverage for up to two years following such termination and Mr. McAnally will be entitled to receive a cash-out payment in respect of his options if (i) he does not resign from employment without "good reason" (as defined in the McAnally Agreement), or (ii) he is terminated without "cause" (as defined in the McAnally Agreement) by a successor, prior to the first anniversary of the change in control. The McAnally Agreement also contains customary covenants regarding nondisclosure of confidential information and non-competition and non-solicitation restrictions. 47

STOCK PURCHASE PLAN AND ADDITIONAL MANAGEMENT SHARES Under the CDW Holding Corporation Stock Purchase Plan (the "Stock Purchase Plan"), the Compensation Committee, which is responsible for administering the Stock Purchase Plan, may offer to certain executives, officers, and other key employees of the Company (the "Purchase Plan Participants") the opportunity to purchase up to an aggregate of 55,000 shares of Class A Common Stock (the "Purchase Plan Shares"). Purchase Plan Participants are selected by reason of their expected contribution to the growth and success of CDW and WESCO. The Board may at any time amend or terminate the Stock Purchase Plan, but may not adversely affect the rights of any Purchase Plan Participant with respect to Purchase Plan Shares purchased prior to such action, unless the Purchase Plan Participant consents. As of December 31, 1997, 30,014 shares were issued and outstanding, and 24,986 shares remained available for sale, under the Stock Purchase Plan. In addition, as of December 31, 1997, CDW has sold 54,150 shares of Class A Common Stock (the "Additional Management Shares") to key management employees (including Named Executives), non-employee directors and other investors otherwise than pursuant to the Stock Purchase Plan. The outstanding Purchase Plan Shares and the Additional Management Shares were sold at a price per share equal to the estimated fair market value (as defined in the related stock subscription agreements described below) per share on the date of sale as determined by the Board. In conjunction with the purchase of the Purchase Plan Shares and the Additional Management Shares, CDW has granted to the purchasers pursuant to the CDW Holding Corporation Stock Option Plan options to purchase shares of Class A Common Stock equal to approximately one and one-third times the number of Purchase Plan Shares or Additional Management Shares purchased. See "--Stock Option Plan." None of the Named Executives currently participates in the Stock Purchase Plan, and no Additional Management Shares were sold to any of the Named Executives during 1997. STOCK SUBSCRIPTION AGREEMENTS Each Purchase Plan Participant is required to enter into a stock subscription agreement (a "Stock Subscription Agreement") specifying the purchase price for the Purchase Plan Shares being purchased and such other terms consistent with the Stock Purchase Plan as the Compensation Committee determines. Unless the Compensation Committee otherwise determines, each Stock Subscription Agreement provides that the Purchase Plan Participant is entitled to the benefits of, and bound by the obligations in, the Registration and Participation Agreement, including certain demand and "piggyback" registration rights thereunder. See "Shares Eligible for Future Sale--Registration and Participation Agreement." The Stock Subscription Agreements also contain certain transfer restrictions, take-along rights in favor of Fund IV and repurchase rights and obligations of CDW, all of which will terminate upon consummation of the Offerings. The Additional Management Shares have been issued pursuant to Stock Subscription Agreements containing substantially similar provisions. STOCK OPTION PLAN Under the CDW Holding Corporation Stock Option Plan (the "Stock Option Plan"), the Compensation Committee, which is responsible for administering the Stock Option Plan, may grant to certain executives, officers, and other key employees of the Company (the "Option Plan Participants") up to an aggregate 181,000 options to purchase one share, subject to adjustment, of Class A Common Stock (the "Options"). Options that are canceled, terminated or forfeited without exercise will again be available for grant. Option Plan Participants are selected by reason of their expected contribution to the growth of CDW and WESCO. The Board may at any time amend or terminate the Stock Option Plan, but may not adversely affect the rights of any Option Plan Participant with respect to Options granted prior to such action, unless the Option Plan Participant consents. As of December 31, 1997, 103,310 Options had been granted, of which (1) 5,142 Options had been exercised, (2) 3,424 Options had been canceled without exercise, (3) 94,744 Options with a weighted average exercise price of $108.75 per share remained outstanding, (4) 33,848 Options with a weighted average exercise price of $103.06 were exercisable. After giving effect to the foregoing, 81,114 Options remained available for grant under the Stock Option Plan. The outstanding Options were granted with an exercise price per share equal to the estimated fair market value (as defined in the related stock option agreements described below) per share on the date of grant as determined by the Board. The foregoing does not include (a) options to acquire 25,100 shares 48

of Class A Common Stock outstanding, and options to acquire 24,900 shares of Class A Common Stock available for grant, under the CDW Holding Corporation Stock Option Plan for Branch Employees, (b) options to acquire 100,000 shares of Class A Common Stock granted to Westinghouse in connection with the Acquisition or (c) options to acquire 120,000 shares of Class A Common Stock to be available for grant under the contemplated LTIP, approximately 60,000 of which will be awarded to executives and key management personnel at the time of the Offerings. Upon establishment of the LTIP, CDW intends to reduce the number of Options available for grant under the Stock Option Plan to approximately 31,000. See "--Stock Option Plan for Branch Employees," "Certain Transactions and Relationships--Westinghouse" and "--Long-Term Incentive Plan." In addition, in connection with the Avon Electrical acquisition, two principals of the seller purchased 1,992 shares of Class A Common Stock at a price per share of $250.97. See "Business--Acquisitions." CHANGE IN CONTROL PROVISIONS In the event of a "change in control" (as defined in the Stock Option Plan), outstanding Options, whether or not exercisable, will be canceled in exchange for a cash payment with respect to each share of Class A Common Stock subject to such Options equal to the excess of (1) the value per share of the Class A Common Stock in the transaction giving rise to the change in control over (2) the per share exercise price, unless the Compensation Committee determines in good faith, prior to the change in control, that the outstanding Options will be honored or assumed by the successor in a manner that provides the Option Participants with rights at least as favorable as those prevailing immediately prior to the change in control. The Offerings will not result in a change in control. STOCK OPTION AGREEMENTS Each Option Plan Participant is required to enter into a stock option agreement (a "Plan Option Agreement") specifying the exercise price and duration of the Options being granted and such other terms consistent with the Stock Option Plan as the Compensation Committee determines. Certain other terms of the Plan Option Agreement are summarized below. EXERCISE OF OPTIONS. Unless the Compensation Committee otherwise determines, Options become exercisable in one-third installments on each of the third, fourth and fifth anniversary of the date of grant. The Compensation Committee has granted Options to certain Named Executives and other senior executives that become exercisable in one-fifth installments on each of the first five anniversaries of the date of grant. Upon exercise of an Option, the Option Plan Participant is required to enter into a stock subscription agreement in substantially the form required under the Stock Purchase Plan. See "--Stock Purchase Plan." The exercise price of any Option may not be less than the fair market value (as defined in the Stock Option Plan) per share of Class A Common Stock as of the date of grant. TERMINATION OF OPTIONS. All Options terminate on the tenth anniversary of the date of grant, unless terminated earlier as described below. Upon termination of an Option Plan Participant's employment with the Company, unless otherwise determined by the Compensation Committee, (1) any unexercisable Options held by such Option Plan Participant will terminate and will not be exercisable, (2) in the case of termination other than for "cause" (as defined in the Stock Option Plan), then exercisable Options will terminate within certain specified periods depending upon the circumstances of the termination of employment, and (3) in the case of termination for cause, all Options held by such Option Plan Participant, whether or not then exercisable, will terminate immediately. TRANSFERABILITY OF OPTIONS; REPURCHASE OF OPTIONS. The Options will not be transferable or assignable other than by will or by the laws of descent, and an Option can be exercised only by the Option Plan Participant to whom it is granted or by the Option Plan Participant's estate or designated beneficiary upon such Option Plan 49

Participant's death. Unless the Compensation Committee otherwise determines, each Plan Option Agreement provides that the Option Plan Participant, in respect of shares purchased upon the exercise of any Option, is entitled to the benefits of, and bound by the obligations in, the Registration and Participation Agreement, including certain demand and "piggyback" registration rights thereunder. See "Shares Eligible for Future Sale--Registration and Participation Agreement." The Plan Option Agreements also contain certain repurchase rights and obligations of the Company, which will terminate upon the consummation of the Offerings. STOCK OPTION PLAN FOR BRANCH EMPLOYEES Under the CDW Holding Corporation Stock Option Plan for Branch Employees (the "Branch Option Plan"), the Compensation Committee, which is responsible for administering the Branch Option Plan, may grant to branch managers and other key employees of WESCO employed at a branch or contributing significantly to growth and profitability of a branch (the "Branch Participants") up to 50,000 options, each to purchase one share, subject to adjustment, of Class A Common Stock (the "Branch Options"). Options that are canceled, terminated or forfeited without exercise will again be available for grant. The Board may at any time amend or terminate the Branch Option Plan, but may not adversely affect the rights of any Branch Participant with respect to Branch Options granted prior to such action, unless the Branch Participant consents. As of December 31, 1997, 25,250 Branch Options had been granted, of which (1) 150 Branch Options had been cancelled without exercise, (2) 25,100 Branch Options with a weighted average exercise price of $195.40 per share were outstanding, and (3) none were exercisable. After giving effect to the foregoing, 24,900 Branch Options remained available for grant under the Branch Option Plan. The outstanding Branch Options were granted with an exercise price per share determined by the Board to represent the estimated fair market value (as defined in the related Branch Option Agreements described below) per share on the date of grant. None of the Named Executives currently participate in the Branch Option Plan. Options are granted to Branch Participants as soon as practicable following the end of each performance period under the Branch Option Plan. The first such performance period commenced on February 28, 1994 and ended on December 31, 1996, and the second such performance period commenced on January 1, 1997 and is scheduled to end on December 31, 1999. Branch Options are allocated to branch or division employees by the Compensation Committee based primarily on the attainment by such branch or division of performance objectives during each performance period. CHANGE IN CONTROL PROVISIONS In the event of a "change in control" (as defined in the Branch Option Plan), outstanding Branch Options, whether or not exercisable, will be canceled in exchange for a cash payment with respect to each share of Class A Common Stock subject to such Branch Options equal to the excess of (1) the value per share of the Class A Common Stock in the transaction giving rise to the change in control over (2) the per share exercise price, unless the Compensation Committee determines in good faith, prior to the change in control, that the outstanding Branch Options will be honored or assumed by the successor in a manner that provides the Branch Participants with rights at least as favorable as those prevailing immediately prior to the change in control. The Offerings will not result in a change in control. BRANCH OPTION AGREEMENTS Each Branch Participant is required to enter into a stock option agreement (a "Branch Option Agreement") specifying the exercise price and duration of the Branch Options being granted and such other terms consistent with the Branch Option Plan as the Compensation Committee determines. Certain other terms of the Branch Option Agreement are summarized below. EXERCISE OF BRANCH OPTIONS; EXERCISE PRICE. Except as otherwise determined by the Compensation Committee or in connection with a change in control, Branch Options become exercisable in one-third 50

installments on each of the first, third and fifth anniversaries of the date of grant. Upon exercise of a Branch Option, the Branch Plan Participant is required to enter into a stock subscription agreement in substantially the form required under the Stock Purchase Plan. See "--Stock Purchase Plan." The per share exercise price of any Branch Option may not be less than the greatest of (1) the fair market value (as defined in the Branch Option Plan) per share of Class A Common Stock as of the end of the related performance period, (2) such fair market value as of the date of grant and (3) $100. TERMINATION OF BRANCH OPTIONS. All Branch Options terminate on the tenth anniversary of the date of grant, unless terminated earlier as described below. Upon termination of a Branch Participant's employment with WESCO, unless otherwise determined by the Compensation Committee, (1) any unexercisable Branch Options held by such Branch Participant will terminate and will not be exercisable, (2) in the case of termination other than for "cause" (as defined in the Branch Option Plan), then exercisable Branch Options will terminate within certain specified periods depending upon the circumstances of the termination of employment, and (3) in the case of termination for cause (as defined in Branch Option Plan), all Branch Options held by such Branch Participant, whether or not then exercisable, will terminate immediately. TRANSFERABILITY OF BRANCH OPTIONS; REPURCHASE OF BRANCH OPTIONS. The Branch Options will not be transferable or assignable other than by will or by the laws of descent, and a Branch Option can be exercised only by the Branch Participant to whom it is granted or by the Branch Participant's estate or designated beneficiary upon such Branch Participant's death. Unless the Compensation Committee otherwise determines, each Branch Option Agreement provides that the Branch Plan Participant, in respect of shares purchased upon the exercise of any Branch Option, is entitled to the benefits of, and bound by the obligations in, the Registration and Participation Agreement, including certain demand and "piggyback" registration rights thereunder. See "Shares Eligible for Future Sale--Registration and Participation Agreement." The Branch Option Agreements also contain certain repurchase rights and obligations of CDW and WESCO, which will terminate upon the consummation of the Offerings. LONG-TERM INCENTIVE PLAN In connection with the Offerings, the Company intends to establish a Long Term Incentive Plan (the "LTIP") under which selected management employees of the Company will be eligible to receive grants of equity awards with respect to the Class A Common Stock. Under the terms of the LTIP, an aggregate of 120,000 shares of Class A Common Stock will be authorized for award. Pursuant to the terms of the LTIP, the Compensation Committee will be authorized to grant awards in the form of stock options, stock appreciation rights, restricted stock, performance shares and deferred stock units. In connection with the Offerings, options to purchase approximately 60,000 shares of Class A Common Stock (the "Initial Options") will be awarded to executives and other key management employees selected by the Board. The Initial Options will have a ten year term and an exercise price equal to the Offering price. Subject to the option holder's continued employment, one-half of the Initial Options will generally become vested if the average market value of the Class A Common Stock over a two month period equals or exceeds 150% of the Offering price and the remaining one-half of the Initial Options will generally become vested if the average market value of the Class A Common Stock over a two month period equals or exceeds 200% of the Offering price, provided that all of the Initial Options will become vested as of the eighth anniversary of the date of grant without regard to the then market value of the Class A Common Stock. The LTIP will provide that in the event of a change in control of CDW or WESCO (as defined in the LTIP), all then outstanding awards will become fully vested and all restrictions on transfer applicable to any such award will lapse, unless the individual award agreement evidencing any such award provides otherwise. 51

Ames, Barbe, Hendrix and Walker served on the Compensation Committee. Messrs. Ames, Barbe and Hendrix are each principals of CD&R. The Company paid CD&R fees of $400,000 for advisory, management consulting and monitoring services rendered during 1997. The Company has agreed to indemnify certain members of the Board and CD&R against liabilities incurred under securities laws, including in connection with the Offerings, or with respect to their services for the Company. See "Certain Transactions and Relationships--CD&R and Fund IV." 52

CERTAIN TRANSACTIONS AND RELATIONSHIPS CD&R AND FUND IV Fund IV, which is CDW's largest stockholder, is a private investment fund managed by CD&R. Amounts contributed to Fund IV by its limited partners are invested at the discretion of the general partner, in equity or equity-related securities of entities formed to effect leveraged buy-out transactions, and in the equity of corporations where the infusion of capital coupled with the provision of managerial assistance by CD&R can be expected to generate returns on investments comparable to returns historically achieved in leveraged buy- out transactions. The general partner of Fund IV is Associates IV. Each of B. Charles Ames, William A. Barbe and Leon J. Hendrix, Jr. is a principal of CD&R, a general partner of Associates IV and a director of the Company. See "Management--Directors and Executive Officers." CDW was formed by CD&R to effect the Acquisition. In connection with the Acquisition, Fund IV acquired 833,280 shares of Class A Common Stock at a purchase price of $100.00 per share, of which shares are being offered hereby. See "Security Ownership by Management and Principal Stockholders" and "Selling Stockholders." Beginning in March 1994, the Company has paid CD&R monthly fees of $33,333 plus related out-of-pocket expenses, for advisory, management consulting and monitoring services, and it is expected that such fees will continue in the future. Under the terms of WESCO's lending arrangements, such fees must be determined by arms length negotiation and must be reasonable. Under the Registration and Participation Agreement, such fees may not exceed $1 million during any fiscal year. In connection with the Acquisition and arranging the financing thereof, the Company paid CD&R a fee of approximately $4.2 million and reimbursed CD&R for its out-of-pocket expenses of $47,227. None of the principals of CD&R who serve as directors of the Company receive directors' fees. The Company has entered into an indemnification agreement with CD&R and Fund IV pursuant to which the Company has agreed, subject to certain exceptions, to indemnify the members of its boards of directors, as well as CD&R, Fund IV and certain of their associates and affiliates (the "Indemnitees"), to the fullest extent allowable under applicable Delaware law and to indemnify the Indemnitees against any suits, claims, damages or expenses which may be made against or incurred by them under applicable securities laws in connection with offerings of securities of CDW, including the Offerings, liabilities to third parties arising out of any action or failure to act by the Company, and, except in cases of gross negligence or intentional misconduct, the provision by CD&R of advisory, management consulting and monitoring services. MANAGEMENT LOANS From time to time following the Acquisition, executive officers have purchased shares of Class A Common Stock from CDW. A portion of the purchase price paid for the Class A Common Stock purchased by such executive officers has been financed by full-recourse bank loans guaranteed by WESCO. Since February 28, 1994, Messrs. Burke, Burleson, Goodwin, Haley, Kramp, Mehta, Piraino, Swed, Thimjon and Vanderhoff have had outstanding loans guaranteed by WESCO. The largest aggregate amount of guaranteed indebtedness outstanding on such loans at any time since February 28, 1994 for Messrs. Burke, Burleson, Goodwin, Haley, Kramp, Mehta, Piraino, Swed, Thimjon and Vanderhoff was $167,262, $68,800, $161,200, $1,377,956, $68,700, $587,959, $167,262, $343,200, $155,000 and $34,400, respectively. As of December 31, 1997, Messrs. Burke, Burleson, Goodwin, Haley, Kramp, Mehta, Piraino, Swed, Thimjon and Vanderhoff owed $167,262, $68,800, $161,200, $1,377,956, $68,700, $587,959, $167,262, $343,200, $155,000 and $34,400, respectively, on such loans. WESTINGHOUSE On February 28, 1994, CDW completed the acquisition of all of the assets and certain liabilities of the Westinghouse Electric Supply Company division of Westinghouse, WESCO's Predecessor. In connection with the Acquisition, Westinghouse acquired certain securities of, and entered into certain agreements with, CDW as 53

described below. Since the Acquisition, WESCO has continued to purchase products and services from, and sell products and provide services to, Westinghouse. See Note 13 to the consolidated financial statements. SHARES, OPTIONS AND MORTGAGE NOTES. In connection with the Acquisition, Westinghouse acquired 100,000 shares of Class A Common Stock (the "Westinghouse Shares") and an option to purchase an additional 100,000 shares of Class A Common Stock, subject to adjustment, at an exercise price of $100 per share (the "Westinghouse Option"). The Westinghouse Option is exercisable any time prior to termination on February 28, 1999. The Westinghouse Shares, the Westinghouse Option and any shares issuable on exercise of the Westinghouse Option are subject to a right of first refusal in favor of CDW and Fund IV, which first refusal right will terminate upon the consummation of the Offerings. Westinghouse is a party to the Registration and Participation Agreement, pursuant to which it has, among other rights, certain demand and "piggy-back" registration rights. See "Shares Eligible for Future Sales-- Registration and Participation Agreement." After giving effect to the Offerings, Westinghouse will hold shares of Class A Common Stock and options to purchase an additional shares, representing in the aggregate % of the Class A Common Stock on a fully diluted basis. Westinghouse also acquired in connection with the Acquisition, the Mortgage Notes, which are secured by liens on all of the Company's owned real property. See "Description of Certain Indebtedness--Mortgage Notes." OTHER AGREEMENTS. Also in connection with the Acquisition, Westinghouse entered into various agreements with the Company including a five-year non- competition agreement which remains in effect through February 28, 1999; a transitional services agreement which is no longer in effect; and an agreement (the "Letter Agreement") pursuant to which, among other things, Fund IV and CDW agreed to vote for, or cause to be voted for, one Westinghouse nominee to the Boards of Directors of CDW and each of its subsidiaries. Westinghouse has not exercised its rights to nominate such directors. In addition, WESCO purchases products and services from and sells products to Westinghouse in the ordinary course of business. WESCO purchases of products and services from Westinghouse amounted to $27,481,000, $19,115,000 and $15,498,000 in 1995, 1996 and 1997, respectively, and WESCO sales to Westinghouse amounted to $27,311,000, $21,192,000 and $21,666,000 in 1995, 1996 and 1997, respectively. See Note 13 to consolidated financial statements. The Letter Agreement, and Westinghouse's rights thereunder, will terminate upon consummation of the Offerings. In addition, Westinghouse agreed to indemnify the Company with respect to certain matters in connection with the Acquisition, including certain liabilities arising under Environmental Laws. CDW has made a claim under this indemnity for certain environmental liabilities in the amount of $1.5 million, which Westinghouse is disputing. 54

SELLING STOCKHOLDERS The Selling Stockholders acquired their shares of Class A Common Stock in connection with the Acquisition. The transferability of the shares held by the Selling Stockholders is restricted by federal and state securities laws and by the Registration and Participation Agreement, and by the stock subscription agreement pursuant to which such shares were issued. Under the Registration and Participation Agreement, the Selling Stockholders have certain rights to require CDW to register shares of Class A Common Stock under the federal securities laws, and to register or qualify such shares for resale under state securities laws. All the shares of Class A Common Stock offered by the Selling Stockholders hereby are being registered pursuant to such registration rights. The Registration and Participation Agreement requires CDW to pay all expenses incurred by the Selling Stockholders with respect to the Offerings, other than underwriting discounts and commissions, transfer taxes applicable to the Class A Common Stock to be sold by the Selling Stockholders and certain legal fees. As required under the Registration and Participation Agreement, CDW has agreed to pay the fees and expenses of one law firm to represent certain Selling Stockholders in connection with the Offerings. The Company has agreed to indemnify the Selling Stockholders and the Underwriters, and the Selling Stockholders have agreed to indemnify the Company, its directors, controlling persons and officers who have signed the Registration Statement of which this Prospectus is a part and the Underwriters as to certain matters relating to the Class A Common Stock to be sold by the Selling Stockholders. Upon registration and sale, such shares of Class A Common Stock will be free of the restrictions noted above other than restrictions under the Securities Act with respect to persons who may be deemed to be affiliates of CDW for purposes of the Securities Act. The following table sets forth certain information with respect to the Selling Stockholders and their beneficial ownership of the Class A Common Stock as of December 31, 1997 and as adjusted to reflect the sale of the Class A Common Stock offered by the Selling Stockholders hereby.

DESCRIPTION OF CAPITAL STOCK The following description of CDW's capital stock does not purport to be complete and is qualified in its entirety by reference to applicable Delaware law and to the provisions of CDW's Certificate of Incorporation and By-laws. Copies of the forms of Certificate of Incorporation and By-laws have been filed as exhibits to the Registration Statement of which this Prospectus forms a part. CDW's authorized capital stock consists of 2,000,000 shares of Class A Common Stock, par value $.01 per share, and 2,000,000 shares of Class B Common Stock, par value $.01 per share. As of March , , CDW had outstanding shares of Class A Common Stock, no shares of Class B Common Stock, options to purchase shares of Class A Common Stock, of which options for shares were exercisable and options for shares became exercisable over the next five years. As of March , there were holders of record of Class A Common Stock. CLASS A COMMON STOCK VOTING RIGHTS. Each holder of shares of Class A Common Stock is entitled to one vote per share on all matters to be voted on by stockholders. Holders of Class A Common Stock are not entitled to cumulative votes in the election of directors. DIVIDEND RIGHTS. The holders of Class A Common Stock are entitled to dividends and other distributions if, as and when declared by the Board out of assets legally available therefor, subject to the rights of any holder of preferred stock, restrictions set forth in the Company's credit facilities and restrictions, if any, imposed by other indebtedness outstanding from time to time. See "Dividend Policy" and "Management's Discussion and Analysis of Financial Conditions and Results of Operations--Liquidity and Capital Resources." The holders of Class A Common Stock and Class B Common Stock are entitled to equivalent per share dividends and distributions. OTHER RIGHTS. Upon the liquidation, dissolution or winding up of CDW, the holders of shares of Class A Common Stock would be entitled to share pro rata (on an equal basis with the holders of the Class B Common Stock) in the distribution of all of CDW's assets remaining available for distribution after satisfaction of all its liabilities and the payment of the liquidation preference of any outstanding preferred stock. The holders of Class A Common Stock have no preemptive or other subscription rights to purchase shares of CDW, nor are they entitled to the benefits of any sinking fund provisions. No share of Class A Common Stock issued in connection with or outstanding prior to the Offerings is subject to any further call or assessment. EXCHANGE RIGHTS. In the event that Fund IV makes a distribution of shares of Class A Common Stock to its limited partners and, following such distribution, one of its limited partners would then be subject to limitations under the Bank Holding Company Act of 1956 (the "Bank Holding Act") on its ability to hold more than 5% of the voting stock of CDW, Fund IV is entitled to exchange a certain number of shares of its Class A Common Stock into the same number of shares of Class B Common Stock so as to permit it to distribute shares of Class B Common Stock to such limited partners without exceeding the limitations under the Bank Holding Act. CLASS B COMMON STOCK The Class B Common Stock is identical to the Class A Common Stock in all respects except that the holders of Class B Common Stock will have no right to vote, except as required by law. Shares of Class B Common Stock automatically convert into the same number of shares of Class A Common Stock upon the sale or transfer by the holder thereof to a non-affiliate. To the extent permitted by law, each holder of Class B Common Stock is entitled to convert any or all shares of Class B Common Stock held into the same number of shares of Class A Common Stock. The Class B Common Stock was intended to meet the needs of several limited partners in Fund IV which may be subject to limitations under the Bank Holding Act on their ability to hold more than 5% of the 58

voting stock of CDW in the event Fund IV were to distribute its shares of Class A Common Stock to such limited partners. It is not anticipated that additional shares of Class B Common Stock will be issued except in the event that Fund IV distributes shares of Common Stock to such limited partners. See "--Class A Common Stock--Exchange Rights." Following the Offerings, Fund IV will hold shares of Class A Common Stock. Fund IV has no present plans to make a distribution of shares of Class A Common Stock held by it to any of its investors. Because shares of Class B Common Stock are issuable only upon the exchange of shares of Class A Common Stock, the issuance of shares of Class B Common Stock would not increase the total number of shares of Common Stock outstanding on such date. TRANSFER AGENT AND REGISTRAR has been appointed as the transfer agent and registrar for the shares of Common Stock. CERTAIN EFFECTS OF AUTHORIZED BUT UNISSUED STOCK After consummation of the Offerings, CDW will have unissued and unreserved shares of Class A Common Stock. These additional shares may be utilized for a variety of corporate purposes, including future public offerings to raise additional capital and for facilitating corporate acquisitions. Except pursuant to the stock option plans described herein, CDW does not currently have any plans to issue additional shares of Common Stock. One of the effects of unissued and unreserved shares of capital stock may be to enable the Board to render more difficult or discourage an attempt to obtain control of CDW by means of a merger, tender offer, proxy contest or otherwise, and thereby to protect the continuity of CDW's management. If, for example, the Board were to determine that a takeover proposal was not in CDW's best interests, such shares could be issued by the Board without stockholder approval in one or more private transactions or other transactions that might prevent or render more difficult or costly the completion of the takeover transactions by diluting the voting or other rights of the proposed acquiror or insurgent stockholder group, by creating a substantial voting block in institutional or other hands that might undertake to support the position of the incumbent Board, by effecting an acquisition that might complicate or preclude the takeover, or otherwise. 59

DESCRIPTION OF CERTAIN INDEBTEDNESS CREDIT FACILITIES GENERAL. On February 13, 1998, WESCO and WESCO Distribution-Canada, Inc. ("WESCO Canada") amended their credit agreements with separate bank groups. The amended credit agreements (the "Credit Facilities") provide for an aggregate $445 million of revolving credit facilities. Under the agreement with the U.S. lenders, WESCO may borrow up to $400 million including a swing line subfacility of $10 million and a letter of credit subfacility of $35 million (as amended, the "U.S. Credit Facility"). Under the agreement with the Canadian lenders, WESCO Canada may borrow up to Cdn$62.7 million, including a swing line subfacility of Cdn$5 million, a letter of credit subfacility of Cdn$5 million and an acceptance facility (as amended, the "Canadian Credit Facility"). Borrowings may be used for general corporate purposes including acquisitions. Borrowings are subject to certain conditions, including, if WESCO fails to meet certain financial tests, a borrowing base requirement based on eligible accounts and inventory. The Credit Facilities will terminate on February 28, 2001. The obligations under the Credit Facilities and related guarantees are unsecured. GUARANTY. Borrowings under the U.S. Credit Facility are guaranteed by CDW; while borrowings under the Canadian Credit Facility are guaranteed by WESCO and (indirectly) by CDW. INTEREST AND FEES. Interest on outstanding borrowings under the U.S. Credit Facility accrues at a floating rate based, at WESCO's option, upon (1) LIBOR for one, two, three or six months plus 1.00% or (2) the greater of (a) the federal funds rate plus 0.50% or (b) the prime rate plus 0.25%. The applicable margins over LIBOR and the prime rate are subject to reduction if WESCO meets certain debt rating requirements or other financial tests. At December 31, 1997, the applicable margins were 0.28% and 0.00%, respectively. Borrowings under the Canadian Credit Facility bear interest at the higher of (1) the rate offered by certain Canadian banks for acceptances plus 0.50% and (2) the Canadian prime rate. The margin over the Canadian prime rate is subject to reduction if WESCO Canada meets certain financial tests. At December 31, 1997 the applicable margin was 0.50%. In addition, the Company pays a facility fee on both the U.S. and Canadian Credit Facilities of 0.23% at December 31, 1997. WESCO is also required to pay a letter of credit commission equal to 0.28% per annum (subject to reduction if certain financial tests are met) on the daily amount stated to be available from time to time under each outstanding letter of credit. CERTAIN COVENANTS. The U.S. Credit Facility contains various restrictive covenants (the breach of which would also be an event of default under the Canadian Credit Facility) that, among other things, impose (1) limitations on the incurrence of additional indebtedness or guarantees, other than (a) $10 million to finance fixed or capital assets, (b) $10 million to finance certain acquisitions, (c) $20 million for any corporate purposes, (d) $30 million for any other purpose and (e) $100 million of subordinated indebtedness; (2) limitations on the issuance of additional stock of subsidiaries; (3) limitations on liens or negative pledges, with customary exceptions and an exception for liens to secure up to $10 million of indebtedness to finance the acquisition of fixed or capital assets; (4) customary limitations on investments, loans, acquisitions or advances (although pursuant to a recent amendment to the U.S. Credit Facility, WESCO is no longer subject to a dollar limitation on the size of any acquisition as long as it has complied with its other financial covenants and maintains $25 million in unused commitments); (5) customary limitations on dividends; (6) limitations on the sale, lease or other disposal of assets to a basket of $35 million (however, the covenant permits securitization of assets of up to $100 million); (7) customary limitations on transactions among affiliates which are not arms-length; and (8) customary limitations on entering into new lines of business. In addition, the U.S. Credit Facility imposes certain financial tests that require WESCO to (1) maintain a consolidated net worth of at least $100 million, (2) maintain a funded indebtedness to consolidated EBITDA ratio of 5 to 1 for the quarter ended March 30, 1998, decreasing to 3.75 to 1 at March 31, 2000 and thereafter, determined on a consolidated basis and tested at the end of each quarter for the trailing four quarters, and (3) maintain a fixed charge coverage ratio of not less than 2 to 1, as such terms are defined in the Credit Facilities. 60

EVENTS OF DEFAULT. The U.S. Credit Facility and, by incorporation by reference, the Canadian Credit Facility, contain various events of default, including (1) the failure of Fund IV and its affiliates to own, directly or indirectly, at least 30% of the outstanding voting stock of CDW, (2) an acquisition by a third party or group of a percentage of the outstanding voting stock of CDW greater than 30% or of the power to elect a majority of CDW's Board of Directors and (3) CDW ceasing to own all of the outstanding stock of WESCO or WESCO ceasing to own all of the outstanding stock of WESCO Canada and Realco. Pursuant to certain amendments to the Credit Facilities, the Offerings will not result in a charge of control constituting an event of default under such Credit Facilities. MORTGAGE NOTES A portion of the purchase price for the Acquisition was financed through the issuance by CDW to Westinghouse of a guaranteed first mortgage note in the initial amount of $45 million, due February 28, 2001 (the "Buyer Note") and the issuance by WESCO Canada of a guaranteed first mortgage note to Westinghouse Canada in the original principal amount of Cdn$6.8 million, due February 28, 2001 (the "Canadian Note" and, collectively with the Buyer Note, the "Mortgage Notes"). At the closing of the Acquisition, CDW caused Realco to assume all of its obligations under the Buyer Note. The Buyer Note is guaranteed by CDW and WESCO. The Canadian Note is guaranteed by CDW, WESCO and Realco. The Buyer Note and the Canadian Note are secured by a first mortgage lien on all of the real property owned by Realco and WESCO Canada, respectively. The Buyer Note is a zero coupon note with a yield to maturity of 8% and the Canadian Note bears interest at 8% per annum, accruing semi-annually. Accrued interest payments accrete to the principal amount and are not payable in cash. The entire aggregate principal amount of the Mortgage Notes (including accretion for interest accruals) will mature and become payable on February 28, 2001. The Mortgage Notes contain various covenants, including, among other things, (1) limitations on the incurrence of additional indebtedness, (2) limitations on making certain restricted payments, (3) limitations on transactions with affiliates, (4) limitations on sale of assets or the consolidation with or merger with or into another entity and (5) a restriction on the sale of the mortgaged properties. In addition, the Mortgage Notes contain customary events of default, including for failure to make payments on the Mortgage Notes, failure to perform covenants, defaulting on the payment of other indebtedness in an aggregate principal amount exceeding $35 million, and the insolvency or bankruptcy of the Company. Finally, the Mortgage Notes provide that CDW shall offer to prepay them upon a Change of Control, which is defined to include (1) prior to the consummation of an initial public offering after which the public owns more of the outstanding common stock of CDW than does Westinghouse (a "Specified Public Offering"), Fund IV and its affiliates ceasing to have the power to elect a majority of the members of the Board of Directors; (2) after the consummation of a Specified Public Offering, any person or group (other than Fund IV and its affiliates or Westinghouse) owning more than 30% of the total voting stock of CDW and more than the total voting stock of CDW owned by Fund IV and its affiliates; (3) CDW owning less than all of the outstanding equity securities of WESCO or Realco; (4) WESCO owning less than all the outstanding equity securities of Realco or WESCO Canada; or (5) during any two-year period, individuals who at the beginning of such period constituted the Board of Directors together with any new directors elected by the directors then still in office who were directors at the beginning of such period ceasing for any reason to constitute a majority of the Board of Directors. ACQUISITION NOTES In connection with certain acquisitions, WESCO has issued $2.2 million principal amount of senior convertible notes (the "Acquisition Notes"). By their terms, concurrent with the consummation of the Offerings each of the Acquisition Notes will be mandatorily converted into shares of Class A Common Stock at a price per share equal to the offering price in the Offerings. Assuming a closing date for the Offerings of , 1998 and an offering price of $ per share (the midpoint of the range), an aggregate shares of Class A Common Stock would be issued upon conversion of the Acquisition Notes. WESCO funded a portion of the purchase price of the two acquisitions that closed in January 1998 with $15 million aggregate principal amount of its unsecured notes, maturing by mid-1999, up to $5 million of which may be converted to shares of Class A Common Stock at the Offering price at the election of the holder, which election is required to be made prior to the Offerings. See "Business--Acquisitions." 61

SHARES ELIGIBLE FOR FUTURE SALE After completion of the Offerings, CDW will have shares of Class A Common Stock outstanding, and shares of Class A Common Stock subject to outstanding stock options and no shares of Class B Common Stock outstanding. Of these shares, the shares of Class A Common Stock sold in the Offerings (and the shares of Class B Common Stock for which such shares of Class A Common Stock will be convertible) will be freely tradeable without restriction under the Securities Act, except by persons who may be deemed to be "affiliates" of CDW, as that term is defined in Rule 144 under the Securities Act. All the remaining shares of Class A Common Stock (including any shares issued upon exercise of such stock options) and any shares of Class B Common Stock for which any such shares of Class A Common Stock are exchanged ("Restricted Shares") may not be sold unless they are registered under the Securities Act or are sold pursuant to an exemption from registration, including an exemption contained in Rule 144 under the Securities Act. In general, under Rule 144, if one year has elapsed since the Restricted Shares have been acquired from the issuer or from an affiliate of the issuer (whichever is later), the holder of such Restricted Shares, including for this purpose persons who may be deemed "affiliates" of CDW whether or not they hold Restricted Shares, would be entitled to sell, within any three-month period, up to a number of Restricted Shares that does not exceed the greater of (1) 1% of the then outstanding shares of Class A Common Stock (approximately shares immediately after the Offerings assuming that the Underwriters' over-allotment options are exercised in full) and (2) the average weekly trading volume of the Class A Common Stock on the New York Stock Exchange during the four calendar weeks preceding the date on which notice of the sale is filed with the Commission. Sales under Rule 144 are subject to certain restrictions relating to manner of sale, notice and the availability of current public information about CDW and may be effected only through unsolicited brokers' transactions. A person who is not deemed an "affiliate" of CDW at any time during the 90 days preceding a sale would (but for the "lock-up" arrangements described below) be entitled to sell such Restricted Shares immediately after the Offerings under Rule 144 without regard to the volume or other limitations described above, provided that two years have elapsed since such Restricted Shares were acquired from CDW or an affiliate of CDW. Substantially all of the Restricted Shares have been held for more than two years by the holders thereof, of which shares are held by persons who may be deemed to be "affiliates" of CDW. Accordingly, all of the remaining Restricted Shares may be sold publicly following the expiration of the 180-day "lock-up" arrangements described below. "LOCK-UP" ARRANGEMENTS CDW, the Selling Stockholders and the directors and substantially all of the employees of the Company who own Class A Common Stock have each agreed not to enter into any agreement providing for, or to effect, any public sale, distribution or other disposition of any shares of Common Stock, including sales pursuant to Rule 144 or Rule 144A under the Securities Act, or grant any public option for any such sale, or otherwise cause CDW to register any securities of CDW, for a period of 180 days after the date of the Offerings without the prior written consent of Merrill Lynch & Co. on behalf of the Underwriters, except for the shares of Class A Common Stock offered in connection with the Offerings. After the expiration of such 180-day period, such stockholders (other than "affiliates" of CDW) will, in general, be entitled to dispose of their shares without regard to volume or other restrictions of Rule 144 under the Securities Act. REGISTRATION AND PARTICIPATION AGREEMENT Pursuant to the terms of the Registration and Participation Agreement, existing stockholders of CDW who will collectively own shares of Class A Common Stock (including shares issuable upon the exercise of outstanding stock options) after the Offerings have certain registration rights with respect to their shares of Common Stock (subject to the "lock-up" arrangements described above). After the completion of the 62

Offerings and the expiration of the 180-day "lock-up" period described above, the holders (other than Westinghouse) of at least 20% of CDW's Registrable Securities (as defined in the Registration and Participation Agreement), may request that CDW register some or all of their Registrable Securities. Any time after February 28, 1999 Westinghouse shall have the right upon two occasions to request that CDW register some or all of the Registrable Securities it holds. In addition, if CDW decides to register additional shares of Common Stock (other than, among other limitations, shares of Common Stock to be issued pursuant to employee benefit or option plans), all holders of CDW's Registrable Securities (including Westinghouse) are entitled to participate in such registration, subject to certain cutback provisions. Prior to the Offerings, there has been no public market for the Class A Common Stock and no prediction can be made as to the effect, if any, that market sales of Restricted Shares, the availability of such Restricted Shares for such sales, or the existing stockholders' registration rights will have on the market price of the Class A Common Stock prevailing from time to time. Nevertheless, sales of substantial amounts of Class A Common Stock, or the perception that such sales could occur, could adversely affect prevailing market prices for the Class A Common Stock and could impair CDW's future ability to raise capital through an offering of its equity securities. See "Risk Factors--Shares Eligible for Future Sale." 63

UNITED STATES FEDERAL TAX CONSIDERATIONS FOR NON-U.S. HOLDERS The following is a summary of certain United States federal income and estate tax consequences of the ownership and disposition of Class A Common Stock by non-U.S. holders. As used herein, "non-U.S. holder" means any person or entity that is a beneficial owner of Class A Common Stock, other than (1) a citizen or resident of the United States, (2) a corporation, partnership or other entity created or organized in the United States or under the laws of the United States or of any state of the United States, (3) an estate whose income is includable in gross income for U.S. federal income tax purposes regardless of its source or (4) a trust if (x) a court within the United States is able to exercise primary supervision over the administration of the trust and (y) at least one U.S. person has authority to control all substantial decisions of the trust. Recently enacted legislation authorizes the issuance of Treasury Regulations that, under certain circumstances, could reclassify as a non-U.S. partnership a partnership that would otherwise be treated as a U.S. partnership, or could reclassify as a U.S. partnership a partnership that would otherwise be treated as a non-U.S. partnership. Such regulations would apply only to partnerships created or organized after the date that proposed Treasury Regulations are filed with the Federal Register (or, if earlier, the date of issuance of a notice substantially describing the expected contents of the regulations). This summary is based on provisions of the U.S. Internal Revenue Code of 1986, as amended (the "Code"), existing and proposed Treasury regulations promulgated thereunder (the "Treasury Regulations") and administrative and judicial interpretations thereof, all as of the date hereof and all of which are subject to change, possibly on a retroactive basis. This summary is for general information only. It does not address aspects of United States taxation other than federal income and estate taxation and does not address all aspects of income and estate taxation or any aspects of state, local or non-United States taxation. In addition, this summary does not consider any specific facts or circumstances that may apply to a particular non-U.S. Holder (including U.S. expatriates, and the fact that in the case of a non-U.S. Holder that is a partnership, the U.S. tax consequences of holding and disposing of shares of Class A Common Stock may be affected by certain determinations made at the partner level), nor does it consider the tax consequences to any person who is a shareholder, partner or beneficiary of a holder of Class A Common Stock. PROSPECTIVE PURCHASERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE PARTICULAR U.S. FEDERAL INCOME AND ESTATE TAX CONSEQUENCES TO THEM OF THE OWNERSHIP AND DISPOSITION OF CLASS A COMMON STOCK, AS WELL AS THE TAX CONSEQUENCES UNDER STATE, LOCAL, NON-U.S. AND OTHER U.S. FEDERAL TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN TAX LAWS. INCOME TAX DIVIDENDS. Generally, dividends paid on Class A Common Stock to a non-U.S. holder will be subject to U.S. federal income tax. Except for dividends that are effectively connected with a non-U.S. holder's conduct of a trade or business within the United States, this tax is imposed and collected by withholding at the rate of 30% of the amount of the dividend, unless reduced by an applicable income tax treaty. Under current regulations, dividends paid to an address in a country other than the United States are presumed, absent knowledge to the contrary, to be paid to a resident of such country in determining the applicability of a treaty for such purposes. However, under recently finalized Treasury Regulations relating to withholding of tax on payments to non-U.S. persons, which by their terms apply to dividend and other payments made after December 31, 1998 (the "Final Withholding Regulations"), a non-U.S. holder who is the beneficial owner (within the meaning of the Final Withholding Regulations) of dividends paid on Class A Common Stock and who wishes to claim the benefit of an applicable treaty is generally required to satisfy certain certification and documentation requirements. Certain special rules apply to claims for treaty benefits made by non-U.S. persons that are entities rather than individuals and to beneficial owners (within the meaning of the Final Withholding Regulations) of dividends paid to entities in which such beneficial owners are interest holders. 64

Except as may be otherwise provided in an applicable income tax treaty, dividends paid on Class A Common Stock to a non-U.S. holder that are effectively connected with the holder's conduct of a trade or business within the United States are subject to tax at ordinary U.S. federal income tax rates, which tax is not collected by withholding (except as described below under "--Backup Withholding and Information Reporting"). All or part of any effectively connected dividends received by a non-U.S. corporation may also, under certain circumstances, be subject to an additional "branch profits" tax at a 30% rate, or such lower rate as may be specified by an applicable income tax treaty. A non-U.S. holder who wishes to claim an exemption from withholding for effectively connected dividends is generally required to satisfy certain certification and documentation requirements. A non-U.S. holder that is eligible for a reduced rate of U.S. withholding tax pursuant to a tax treaty may obtain a refund of any excess amounts withheld by filing an appropriate claim for refund with the U.S. Internal Revenue Service (the "I.R.S."). DISPOSITION OF CLASS A COMMON STOCK. Generally, non-U.S. holders will not be subject to U.S. federal income tax (or withholding thereof) in respect of gain recognized on a disposition of Class A Common Stock unless (1) the gain is effectively connected with the holder's conduct of a trade or business within the United States (in which case the "branch profits" tax described above may also apply if the holder is a non-U.S. corporation); (2) in the case of a holder who is a nonresident alien individual and holds Class A Common Stock as a capital asset, such holder is present in the United States for 183 or more days in the taxable year of the sale and certain other conditions are met; or (3) the Company is or has been a "United States real property holding corporation" for U.S. federal income tax purposes (which the Company does not believe it has been or is currently, and does not anticipate becoming) and the holder has held directly or constructively more than 5% of the outstanding Class A Common Stock within the five-year period ending on the date of the disposition. ESTATE TAX If an individual non-U.S. holder owns, or is treated as owning, Class A Common Stock at the time of his or her death, such stock would be subject to U.S. federal estate tax imposed on the estates of nonresident aliens, in the absence of a contrary provision contained in an applicable tax treaty. BACKUP WITHHOLDING AND INFORMATION REPORTING Under certain circumstances, the I.R.S. requires certain information reporting and "backup withholding" at a rate of 31% with respect to certain payments on Class A Common Stock. DIVIDENDS. Under current law, dividends paid on Class A Common Stock to a non-U.S. holder at an address outside the United States are generally exempt from backup withholding tax and U.S. information reporting requirements (but not from regular withholding tax, as discussed above). Under the Final Withholding Regulations, for dividends paid after December 31, 1998, a non- U.S. person must generally provide proper documentation indicating non-U.S. status to a withholding agent in order to avoid backup withholding tax; however, dividends paid to certain exempt recipients (not including individuals) will not be subject to backup withholding even if such documentation is not provided if the withholding agent is allowed to rely on certain regulatory presumptions concerning the recipient's non-U.S. status (including payment to an address outside the United States). BROKER SALES. Payments of proceeds from the sale of Class A Common Stock by a non-U.S. holder made to or through a U.S. office of a broker are generally subject to both information reporting and backup withholding unless the holder certifies its non-U.S. status under penalties of perjury or otherwise establishes entitlement to an exemption. Payments of proceeds from the sale of Class A Common Stock by a non-U.S. holder made to or through a non-U.S. office of a broker generally will not be subject to information reporting or backup withholding. However, payments made to or through certain non-U.S. offices, including the non-U.S. offices of a U.S. broker, are generally subject to information reporting (but not backup withholding) unless the holder certifies its non-U.S. status under penalties of perjury or otherwise establishes entitlement to an exemption. A non-U.S. holder may obtain a refund of any excess amounts withheld under the backup withholding rules by filing an appropriate claim for refund with the I.R.S. 65

UNDERWRITING Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch"), Goldman, Sachs & Co., Bear, Stearns & Co. Inc. and Smith Barney Inc. are acting as representatives (the "U.S. Representatives") of each of the Underwriters named below (the "U.S. Underwriters"). Subject to the terms and conditions set forth in a U.S. purchase agreement (the "U.S. Purchase Agreement") among the Selling Stockholders, the Company and the U.S. Underwriters, and concurrently with the sale of shares of Class A Common Stock to the International Managers (as defined below), the Selling Stockholders have agreed to sell to the U.S. Underwriters, and each of the U.S. Underwriters severally and not jointly has agreed to purchase from the Selling Stockholders, the number of shares of Class A Common Stock set forth opposite its name below. NUMBER OF U.S. UNDERWRITER SHARES ---------------- --------- Merrill Lynch, Pierce, Fenner & Smith Incorporated............................................. Goldman, Sachs & Co. ......................................... Bear, Stearns & Co. Inc....................................... Smith Barney Inc.............................................. --- Total.................................................... === The Company and the Selling Stockholders have also entered into an international purchase agreement (the "International Purchase Agreement") with certain underwriters outside the United States and Canada (the "International Managers" and, together with the U.S. Underwriters, the "Underwriters") for whom Merrill Lynch International, Goldman Sachs International, Bear, Stearns International Limited and Smith Barney Inc. are acting as lead managers (the "Lead Managers"). Subject to the terms and conditions set forth in the International Purchase Agreement, and concurrently with the sale of shares of Class A Common Stock to the U.S. Underwriters pursuant to the U.S. Purchase Agreement, the Selling Stockholders have agreed to sell to the International Managers, and the International Managers severally and not jointly have agreed to purchase from the Selling Stockholders, an aggregate of shares of Class A Common Stock. The initial public offering price per share and the underwriting discount per share of Class A Common Stock will be identical under the U.S. Purchase Agreement and the International Purchase Agreement. In the U.S. Purchase Agreement and the International Purchase Agreement, the several U.S. Underwriters and the several International Managers, respectively, have agreed, subject to the terms and conditions set forth therein, to purchase all of the shares of Class A Common Stock being sold pursuant to each such agreement if any of the shares of Class A Common Stock being sold pursuant to such agreement are purchased. Under certain circumstances, under the U.S. Purchase Agreement and the International Purchase Agreement, the commitments of non-defaulting Underwriters may be increased. The closings with respect to the sale of shares of Class A Common Stock to be purchased by the U.S. Underwriters and the International Managers are conditioned upon one another. The U.S. Representatives have advised the Selling Stockholders and the Company that the U.S. Underwriters propose initially to offer the shares of Class A Common Stock to the public at the initial public offering price set forth on the cover page of this Prospectus, and to certain dealers at such price less a concession not in excess of $ per share of Class A Common Stock. The U.S. Underwriters may allow, and such dealers may reallow, a discount not in excess of $ per share of Class A Common Stock on sales to certain other dealers. After the initial public offering, the public offering price, concession and discount may be changed. The Selling Stockholders have granted an option to the U.S. Underwriters, exercisable for 30 days after the date of this Prospectus, to purchase up to an aggregate of additional shares of Class A Common Stock at the initial public offering price set forth on the cover page of this Prospectus, less the underwriting discount. The U.S. Underwriters may exercise these options solely to cover over-allotments, if any, made on the sale of the 66

Class A Common Stock offered hereby. To the extent that the U.S. Underwriters exercise these options, each U.S. Underwriter will be obligated, subject to certain conditions, to purchase a number of additional shares of Class A Common Stock proportionate to such U.S. Underwriter's initial amount reflected in the foregoing table. The Selling Stockholders have also granted an option to the International Managers, exercisable for 30 days after the date of this Prospectus, to purchase up to an aggregate of additional shares of Class A Common Stock to cover over-allotments, if any, on terms similar to those granted to the U.S. Underwriters. At the request of the Company, the Underwriters have reserved for sale, at the initial public offering price up to of the shares of Class A Common Stock offered hereby to be sold to certain employees of the Company and certain other persons. The number of shares of Class A Common Stock available for sale to the general public will be reduced to the extent such persons purchase such reserved shares. Any reserved shares which are not orally confirmed for purchase within one day of the pricing of the Offerings will be offered by the Underwriters to the general public on the same terms as the other shares offered hereby. The Selling Stockholders, the Company's executive officers and directors, and certain other stockholders have agreed, subject to certain exceptions, not to directly or indirectly (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of or otherwise dispose of or transfer any shares of Class A Common Stock or securities convertible into or exchangeable or exercisable for Class A Common Stock, whether now owned or thereafter acquired by the person or entity executing the agreement or with respect to which the person or entity executing the agreement thereafter acquires the power of disposition, or file a registration statement under the Securities Act with respect to the foregoing or (ii) enter into any swap or other agreement that transfers, in whole or in part, the economic consequence of ownership of the Class A Common Stock whether any such swap or transaction is to be settled by delivery of Class A Common Stock or other securities, in cash or otherwise, without the prior written consent of Merrill Lynch on behalf of the Underwriters for a period of 180 days after the date of this Prospectus. See "Shares Eligible for Future Sale." The U.S. Underwriters and the International Managers have entered into an intersyndicate agreement (the "Intersyndicate Agreement") that provides for the coordination of their activities. Pursuant to the Intersyndicate Agreement, the U.S. Underwriters and the International Managers are permitted to sell shares of Class A Common Stock to each other for purposes of resale at the initial public offering price, less an amount not greater than the selling concession. Under the terms of the Intersyndicate Agreement, the U.S. Underwriters and any dealer to whom they sell shares of Class A Common Stock will not offer to sell or sell shares of Class A Common Stock to persons who are non-U.S. or non-Canadian persons or to persons they believe intend to resell to persons who are non-U.S. or non-Canadian persons, and the International Managers and any dealer to whom they sell shares of Class A Common Stock will not offer to sell or sell shares of Class A Common Stock to U.S. persons or to Canadian persons or to persons they believe intend to resell to U.S. or Canadian persons, except in the case of transactions pursuant to the Intersyndicate Agreement. Prior to the Offerings, there has been no public market for the Class A Common Stock of CDW. The initial public offering price will be determined through negotiations among the Company, the Selling Stockholders, the U.S. Representatives and the Lead Managers. The factors to be considered in determining the initial public offering price, in addition to prevailing market conditions, are price-earnings ratios of publicly traded companies that the U.S. Representatives and Lead Managers believe to be comparable to the Company, certain financial information of the Company, the history of, and the prospects for, the Company and the industry in which it competes, and an assessment of the Company's management, its past and present operations, the prospects for, and timing of, future revenues of the Company, the present state of the Company's development and the above factors in relation to market values and various valuation measures of other companies engaged in activities similar to the Company. There can be no assurance given that an active trading market will develop for the Class A Common Stock or that the Class A Common Stock will trade in the public market subsequent to the Offerings at or above the initial public offering price. 67

Application will be made to list the Class A Common Stock on the New York Stock Exchange under the symbol " ." In order to meet the requirements for listing of the Class A Common Stock on the New York Stock Exchange, the U.S. Underwriters and International Managers have undertaken to sell lots of 100 or more shares to a minimum of 2,000 beneficial owners. The Underwriters and International Managers do not intend to confirm sales of the Class A Common Stock offered hereby to any accounts over which they exercise discretionary authority. CDW and the Selling Stockholders have agreed to indemnify the U.S. Underwriters and the International Managers against certain liabilities, including certain liabilities under the Securities Act, or to contribute to payments which the U.S. Underwriters and International Managers may be required to make in respect thereof. Until the distribution of the Class A Common Stock is completed, rules of the Commission may limit the ability of the Underwriters and certain selling group members to bid for and purchase the Class A Common Stock. As an exception to these rules, the U.S. Representatives are permitted to engage in certain transactions that stabilize the price of the Class A Common Stock. Such transactions consist of bids or purchases for the purpose of pegging, fixing or maintaining the price of the Class A Common Stock. If the Underwriters create a short position in the Class A Common Stock in connection with the Offerings, i.e., if they sell more shares of Class A Common Stock than are set forth on the cover page of this Prospectus, the U.S. Representatives may reduce that short position by purchasing Class A Common Stock in the open market. The U.S. Representatives may also elect to reduce any short position by exercising all or part of the over-allotment option described above. The U.S. Representatives may also impose a penalty bid on certain Underwriters and selling group members. This means that if the U.S. Representatives purchase shares of Class A Common Stock in the open market to reduce the Underwriters' short position or to stabilize the price of the Class A Common Stock, they may reclaim the amount of the selling concession from the Underwriters and selling group members who sold those shares as part of the Offerings. In general, purchases of a security for the purpose of stabilization or to reduce a short position could cause the price of the security to be higher than it might have been in the absence of such purchases. The imposition of a penalty bid might also have an effect on the price of the Class A Common Stock to the extent that it discourages resales of the Class A Common Stock. None of the Company, the Selling Stockholders or any of the Underwriters makes any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the Class A Common Stock. In addition, none of the Company, the Selling Stockholders or any of the Underwriters makes any representation that the U.S. Representatives will engage in such transactions or that such transactions, once commenced, will not be discontinued without notice. 68

Certain legal matters will be passed upon for the Underwriters by Fried, Frank, Harris, Shriver & Jacobson (a partnership including professional corporations), New York, New York. Debevoise & Plimpton also acts and may hereafter act as counsel to CD&R and its affiliates and to CDW and its affiliates. Franci J. Blassberg, Esq., a member of Debevoise & Plimpton, is married to Joseph L. Rice, III, a general partner of Associates IV, the general partner of Fund IV. EXPERTS The consolidated balance sheets of the Company as of December 31, 1996 and 1997 and the consolidated statements of income, stockholders' equity and cash flows of the Company for each of the three years in the period ended December 31, 1997 included in this Prospectus have been included herein in reliance on the report of Coopers & Lybrand L.L.P., independent accountants, given on the authority of that firm as experts in accounting and auditing.

REPORT OF INDEPENDENT ACCOUNTANTS To the Stockholders and Board of Directors of CDW Holding Corporation: We have audited the accompanying consolidated balance sheets of CDW Holding Corporation and subsidiaries as of December 31, 1996 and 1997, and the related consolidated statements of income, stockholders' equity, and cash flows for the three years in the period ended December 31, 1997. These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management as well as evaluating the overall consolidated financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of CDW Holding Corporation and subsidiaries as of December 31, 1996 and 1997, and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 1997, in conformity with generally accepted accounting principles. /s/ COOPERS & LYBRAND L.L.P. 600 Grant Street Pittsburgh, Pennsylvania February 6, 1998, except for Note 18, as to which the date is February 13, 1998.

CDW HOLDING CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS IN THOUSANDS, EXCEPT SHARE DATA) 1. ORGANIZATION: On February 28, 1994, CDW Holding Corporation (CDW) and its subsidiaries (collectively, the Company) completed the acquisition of substantially all of the assets and certain liabilities of Westinghouse Electric Supply Company from Westinghouse Electric Corporation (Westinghouse). The Company was formed by the Clayton & Dubilier Private Equity Fund IV Limited Partnership, managed by Clayton, Dubilier & Rice, Inc. for the purpose of the acquisition. All of the Company's commercial activities, which commenced February 28, 1994, are carried out by WESCO Distribution, Inc. and its subsidiaries (WESCO). WESCO is a wholly-owned subsidiary of CDW. WESCO, headquartered in Pittsburgh, Pennsylvania, is a full-line distributor of electrical supplies and equipment and currently operates branch locations in the United States, Canada, Mexico, Puerto Rico and Guam. The acquisition was accounted for as a purchase and, accordingly, the assets and liabilities acquired have been recorded at their estimated fair value at the date of acquisition, less the excess of the fair value of the assets and liabilities acquired over the purchase price. This excess was allocated to the noncurrent assets of the Company. 2. SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES: Principles of Consolidation: The consolidated financial statements include the accounts of the Company and all of its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The preparation of the consolidated financial statements in conformity with generally accepted accounting principles requires management to make certain estimates and assumptions. These may affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements. They may also affect the reported amounts of revenues and expenses during the reported period. Actual results could differ from these estimates upon subsequent resolution of some matters. Revenue Recognition: Revenues of the Company are recognized at the time of product shipment. Cash Equivalents: Cash equivalents are defined as highly liquid investments with original maturities of 90 days or less when purchased. Inventories: Inventories primarily consist of merchandise purchased for resale and are stated at the lower of cost or market. Cost is determined principally under the average cost method. Property, Buildings and Equipment: Property, buildings and equipment are recorded at cost. Depreciation expense is determined over the estimated useful lives of the assets using the straight-line method. Leasehold improvements are amortized over either their respective lease terms or their estimated lives, whichever is shorter. Expenditures for new facilities and improvements that extend the useful life of an asset are capitalized. Ordinary repairs and maintenance are expensed as incurred. When property is retired or otherwise disposed of, the cost and the related accumulated depreciation are removed from the accounts and any related gains or losses are recorded. F-7

CDW HOLDING CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED) (DOLLARS IN THOUSANDS, EXCEPT SHARE DATA) 2. SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES--CONTINUED: Intangibles: Goodwill and other intangibles arising from acquisitions are being amortized on a straight-line basis over periods not exceeding 25 years. The Company regularly reviews the individual components of the balance by evaluating the estimated future undiscounted cash flows to determine the recoverability of the assets and recognizes, on a current basis, any decrease in value. Trademarks acquired are recorded at cost and are amortized on a straight- line basis over periods not exceeding 25 years. Income Taxes: Deferred income taxes result primarily from temporary differences between financial and tax reporting. A valuation allowance is provided when a portion or all of a deferred tax asset may not be realized. Foreign Currency Translation: The local currency is the functional currency for the Company's operations outside the United States. Assets and liabilities of these operations are translated to U.S. dollars at the exchange rate in effect at each year-end. Income statement accounts are translated at the average exchange rate prevailing during the year. Translation adjustments arising from the use of differing exchange rates from period to period are included as a component of stockholders' equity. Gains and losses from foreign currency transactions are included in net income for the period. Environmental Expenditures: The Company has facilities and operations which distribute certain products that must comply with environmental regulations and laws. Expenditures for current operations are expensed or capitalized, as appropriate. Expenditures relating to existing conditions caused by past operations, and which do not contribute to future revenue, are expensed. Liabilities are recorded when remedial efforts are probable and the costs can be reasonably estimated. Earnings Per Share: Basic earnings per share are computed by dividing net income by the common shares outstanding during the respective periods. Diluted earnings per share are computed by dividing net income by the common and common equivalent shares outstanding during the respective periods. The dilutive effect of common share equivalents is considered in the diluted earnings per share computation using the treasury stock method. Reclassifications: Certain prior year amounts have been reclassified in order to conform with the current presentations. New Accounting Pronouncements: In February 1997, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 128, "Earnings per Share." This Statement, which is effective for the 1997 financial statements, establishes standards for computing and presenting earnings per share and requires restatement of all prior period earnings per share data presented. The provisions of SFAS No. 128 have been adopted and the effects are included in the financial statements. F-8

CDW HOLDING CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED) (DOLLARS IN THOUSANDS, EXCEPT SHARE DATA) 2. SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES--CONTINUED: In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive Income," which establishes standards for reporting and displaying comprehensive income and its components. This Statement requires that all items that are required to be recognized under accounting standards as components of comprehensive income be reported in a financial statement that is displayed with the same prominence as other financial statements. Additionally, the FASB issued SFAS No. 131, "Disclosures about Segments of an Enterprise and Related Information," which establishes standards for the way that public business enterprises report information about operating segments in annual financial statements and related disclosures about products and services, geographic areas and major customers. These Statements are effective for financial statements for fiscal years beginning after December 15, 1997. Management is currently evaluating the implications of these Statements. 3. CONCENTRATIONS OF CREDIT RISK AND SIGNIFICANT SUPPLIERS: The Company distributes its products and extends credit to a large number of customers in the industrial, construction, utility and manufactured structures market. In addition, one supplier accounted for approximately 20%, 18%, and 18% of the Company's purchases for the years ended December 31, 1995, 1996 and 1997, respectively. 4.

CDW HOLDING CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED) (DOLLARS IN THOUSANDS, EXCEPT SHARE DATA) 5. OTHER ASSETS--CONTINUED: Debt issuance costs are being amortized on a straight-line basis, which does not differ significantly from the effective interest rate method, over the term of the related debt (see Note 8). Restricted cash represents proceeds received from the sale of properties which collateralize the First Mortgage Notes. Such proceeds are restricted for either repayment of the First Mortgage Notes or acquisition of additional properties which would be issued as collateral under the First Mortgage Notes (see Note 8). 6.

INCOME TAXES: At the acquisition date, February 28, 1994, the Company had approximately $45,000 of future tax deductions ($18,000 of tax benefits) which resulted in the creation of certain deferred tax assets. A valuation allowance was recorded for the full amount of the assets reflected on the opening balance sheet since the realization of these future benefits was not considered likely at that time. However, at December 31, 1996, all of these deductions had been recognized. The recognition of these benefits resulted in a reduction in noncurrent intangible assets, principally trademarks. The charge in lieu of taxes recognized in 1995 and 1996 represents the amount of tax expense that would have been recognized had the benefits described above been recorded at the time of the acquisition. The provision for income taxes is as follows: 1995 1996 1997 ------- ------- ------- Current: U.S. federal................................. $ 468 $15,360 $16,689 State........................................ 100 2,872 3,067 Foreign...................................... -- 210 1,117 Deferred: U.S. federal................................. 7,218 (1,588) 2,727 State........................................ 1,314 (267) (183) Foreign...................................... 740 523 293 Charge in lieu of taxes...................... 4,950 1,254 -- ------- ------- ------- Provision for income taxes before extraordinary charge........................................ 14,790 18,364 23,710 Tax benefit of extraordinary charge............

The agreements provide for floating rates, based on either Prime or LIBOR in the United States and Prime or Bankers' Acceptance rates in Canada plus a fixed margin. The interest rates for 1996 for the revolving credit loans ranged from 6.3% to 8.3% in the United States and was 3.2% in Canada. The interest rates for 1997 for the revolving credit loans ranged from 6.1% to 8.5% in the United States and was 4.4% to 5.3% in Canada. The weighted- average interest rate was 6.7% and 6.0% for the years ended December 31, 1996 and 1997, respectively (see Note 18). In 1995, the Company terminated the existing credit agreements and refinanced the outstanding indebtedness. In connection with this refinancing, the Company recorded an extraordinary charge of $13,312 ($8,068 after-tax) relating to the write-off of unamortized debt issuance and other costs associated with the early termination of the debt. (B) The Company issued a Zero Coupon First Mortgage Note to Westinghouse for the purchase of the real estate acquired in the United States. This note has a yield to maturity of 8% and a maturity value of $75,519. (C) The Company issued a First Mortgage Note to Westinghouse for the purchase of the real estate acquired in Canada. All interest and principal will be due February 2001. The Company has two interest rate cap agreements with individual notional amounts of $80,000 that expire in March 1998 and August 1999. The aggregate cost of the interest rate caps of $278 is being amortized to interest expense over the period of the agreements on a straight-line basis. The agreements effectively provide a ceiling for interest at rates ranging from 6.8% to 7.0%. The market value of the interest rate caps is estimated to be $42 at December 31, 1997. The agreements contain various restrictive covenants that, among other things, impose (i) limitations on the incurrence of additional indebtedness or guaranties; (ii) limitations on the issuance of additional stock of subsidiaries; (iii) limitations on liens or negative pledges; (iv) limitations on investments, loans, acquisitions or advances; (v) limitations on dividends; (vi) limitations on the sale, lease or other disposal of assets; (vii) limitations on transactions among affiliates which are not arms-length; (viii) limitations on entering into new lines of business; and (ix) limitations on capital expenditures. In addition, the agreements require the Company to meet certain financial tests based on net worth, a funded indebtedness to consolidated EBITDA ratio and fixed charge coverage. F-12

CDW HOLDING CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED) (DOLLARS IN THOUSANDS, EXCEPT SHARE DATA) 8. LONG-TERM DEBT--CONTINUED: The Company is permitted to pay dividends under certain limited circumstances. At December 31, 1997, no retained earnings were available to pay dividends. The Company had outstanding letters of credit in the amount $3,250 at December 31, 1996 and 1997. These letters of credit are used as collateral for performance and bid bonds. The value of these letters of credit approximates contract value. The value of assets collateralized under the aforementioned debt agreements was approximately $651,348 and $719,533 at December 31, 1996 and 1997, respectively. The fair value of the Company's long-term debt is estimated to be approximately $255,620 and $290,035 at December 31, 1996 and 1997, respectively, based on current market interest rates and discounted cash flows. Future principal payments of long-term debt in excess of one year as of December 31, 1997 are as follows: 1999................................ $228,230 2000................................ 385 2001................................ 65,594 2002................................ 66 9. CAPITAL STOCK: Common Stock: There are 2,000,000 shares each of Class A and Class B common stock authorized at a par value of $.01 per share. The Class B common stock is identical to the Class A common stock, except for voting and conversion rights. The holders of Class B common stock have no voting rights. With certain exceptions, Class B common stock may be converted, at the option of the holder, into the same number of shares of Class A common stock. No Class B common stock was outstanding at December 31, 1996 and 1997. At December 31, 1997, shares of common stock reserved for future issuance were as follows: NUMBER OF SHARES ---------------- Stock purchase plan......... 24,986 Stock option plan........... 81,114 Stock option plan for branch employees.................. 24,900 Redeemable Class A Common Stock: Certain employees and key management of the Company who hold Class A common stock and options may require the Company to repurchase, under certain conditions, all of the shares held. This repurchase right terminates upon the consummation of an initial public offering of CDW's Class A common stock. 10. STOCK INCENTIVE PLANS: Stock Purchase Plan: Under the Company's stock purchase plan, certain employees of the Company may be granted an opportunity to purchase CDW's Class A common stock. The maximum number of shares available for purchase F-13

CDW HOLDING CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED) (DOLLARS IN THOUSANDS, EXCEPT SHARE DATA) 10. STOCK INCENTIVE PLANS--CONTINUED: may not exceed 55,000. The purchase price per share is determined by the Board of Directors of the Company to represent fair market value, as defined by the Stock Subscription Agreement. Should the purchase price of the stock be less than the fair market value of the stock at the grant date, such excess will be recorded as compensation expense in the consolidated statement of income. The plan will continue in effect until either the earlier of June 15, 1999, or the date on which all shares of common stock to be offered have been issued. At December 31, 1996 and 1997, a total of 30,504 and 31,304 shares, respectively, have been purchased under the plan. During 1995, 14,624 shares were purchased for a weighted-average share price of $103 under the plan. During 1996, 2,610 shares were purchased for a weighted-average share price of $169 under the plan. During 1997, 800 shares were purchased for a weighted-average share price of $251 under the plan. In conjunction with the purchase of shares pursuant to the plan, the Company has granted options to purchase shares of common stock equal to approximately one and one-third of the number of shares purchased. See the stock option plan described below for further information. Other Stock Purchases: In addition to the stock purchase plan, certain key management employees of the Company, nonemployee directors and other investors were granted an opportunity to purchase CDW's Class A common stock. The purchase price per share was determined by the Board of Directors to represent the fair market value, as defined by the Stock Subscription Agreement, at the date of grant. At each of December 31, 1996 and 1997, 54,150 shares had been purchased. During 1995, 8,140 shares were purchased at a weighted-average share price of $111 under these additional offerings. During 1996, 2,140 shares were purchased at a share price of $195 under an additional offering. Stock Option Plan: Participation in the Company's stock option plan is limited to officers and key employees of the Company. The maximum number of Class A common stock options (and the maximum shares of common stock subject to options) granted under the plan may not exceed 181,000. The exercise price per share is determined by the Board of Directors of the Company, but will not be less than the estimated fair market value, as defined by the Stock Option Agreements, on the grant date. Options granted to a participant will vest and will become exercisable over five years, except in the event of a change in control. Each option terminates on the tenth anniversary of its grant date unless terminated sooner under certain conditions. Stock Option Plan for Branch Employees: The Company also has a stock option plan whose participation is limited to branch managers and other key branch personnel. The Compensation Committee of the Board of Directors of the Company may grant such employees up to 50,000 options. Provisions for exercise price, vesting and termination of these options are substantially the same as the stock option plan described above. F-14

The stock option plans require the Company to repurchase the exercisable portion of the options held by an employee if the employee dies, is disabled or terminated without cause. This repurchase right terminates upon consummation of an initial public offering of CDW's Class A common stock. Since the triggering event requiring the repurchase is considered remote, the Company accounts for the option as a fixed plan and accordingly no compensation expense has been recorded. In connection with the implementation of SFAS No. 123, "Accounting for Stock-Based Compensation," the Company has elected to continue to account for stock-based compensation arrangements under the provisions of Accounting Principles Board (APB) Opinion No. 25, which resulted in no compensation costs being recorded.

EMPLOYEE BENEFITS: A majority of the Company's employees are covered by defined contribution retirement savings plans for their service rendered subsequent to the acquisition date. Westinghouse retains certain retiree pension and health benefits for service rendered prior to formation. U.S. employee contributions of not more than 6% of eligible compensation are matched 50% by the Company. Company contributions for Canadian employees range from 1%--6% of eligible compensation based on years of service. In addition, employer contributions may be made at the discretion of the Board of Directors and can be based on the Company's current year performance. Employees are credited for service with Westinghouse in determining the vesting of Company contributions. For the years ended December 31, 1995, 1996 and 1997, the Company contributed $7,096, $9,256 and $12,453, respectively, which was charged to expense. 13. RELATED PARTIES: Pursuant to an agreement, Clayton, Dubilier & Rice, Inc. provides financial advisory and management consulting services to the Company for an annual fee of approximately $400. WESCO purchases products and services from and sells products to Westinghouse.

In connection with the acquisition, the Company granted Westinghouse an option to purchase 100,000 shares of Class A common stock at a price of $100 per share. The option is exercisable until it terminates on February 28, 1999. The Company has a right of first refusal if Westinghouse decides to sell its option to a third party prior to its termination. The fair value of this option, which was recorded at the acquisition, was $2,500 and is included in the consolidated balance sheets as Common Stock to Be Issued Under Option. 14.

CDW HOLDING CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED) (DOLLARS IN THOUSANDS, EXCEPT SHARE DATA) 14. COMMITMENTS AND CONTINGENCIES--CONTINUED: The Company has litigation arising from time to time in the normal course of business. In management's opinion, any present litigation the Company is aware of will not materially affect the Company's consolidated financial position, results of operations or cash flows. Westinghouse agreed to indemnify the Company for certain environmental liabilities that existed at the time of the acquisition. The Company has made a claim under this indemnity amounting to $1.5 million. The ultimate resolution of this environmental compliance issue is not expected to materially impact the Company's consolidated financial position, results of operations or cash flows. The Company has guaranteed $5,636 in loans to certain stockholders at December 31, 1997. 15.

ACQUISITIONS: During the three years ended December 31,1997, the Company acquired eleven distributors with branches located across the United States for an aggregate purchase price of $12,423 and $158,802 and $19,248, respectively. The largest acquisition, in April 1996, was EESCO, Inc. with headquarters in Chicago, Illinois. These acquisitions resulted in goodwill of approximately $6,146, $59,766 and $5,913 for the years ending 1995, 1996 and 1997, respectively. The acquisitions have been accounted for under the purchase method of accounting for business combinations. The results of operations of these companies are included in the consolidated financial statements from the acquisition dates forward. Pro forma results of these acquisitions, assuming they had been made at the beginning of each year presented, would not be materially different from the results reported. In December 1997, the Company entered into definitive agreements to acquire two distribution businesses for approximately $59,500 financed principally through 45,000 in borrowings under the Company's credit agreement and $14,500 of uncollateralized notes. Up to $5,000 of such notes may be converted to shares of Class F-18

Under the terms of the Intersyndicate Agreement, the U.S. Underwriters and any dealer to whom they sell shares of Class A Common Stock will not offer to sell or sell shares of Class A Common Stock to persons who are non- U.S. or non-Canadian persons or to persons they believe intend to resell to persons who are non-U.S. or non-Canadian persons, and the International Managers and any dealer to whom they sell shares of Class A Common Stock will not offer to sell or sell shares of Class A Common Stock to U.S. persons or to Canadian persons or to persons they believe intend to resell to U.S. or Canadian persons, except in the case of transactions pursuant to the Intersyndicate Agreement. Prior to the Offerings, there has been no public market for the Class A Common Stock of CDW. The initial public offering price will be determined through negotiations among the Company, the Selling Stockholders, the Lead Managers and the U.S. Representatives. The factors to be considered in determining the initial public offering price, in addition to prevailing market conditions, are price-earnings ratios of publicly traded companies that the Lead Managers and U.S. Representatives believe to be comparable to the Company, certain financial information of the Company, the history of, and the prospects for, the Company and the industry in which it competes, and an assessment of the Company's management, its past and present operations, the prospects for, and timing of, future revenues of the Company, the present state of the Company's development and the above factors in relation to market values and various valuation measures of other companies engaged in 68

[ALTERNATE PAGE FOR INTERNATIONAL PROSPECTUS] activities similar to the Company. There can be no assurance given that an active trading market will develop for the Class A Common Stock or that the Class A Common Stock will trade in the public market subsequent to the Offerings at or above the initial public offering price. Application will be made to list the Class A Common Stock on the New York Stock Exchange under the symbol " ." In order to meet the requirements for listing of the Class A Common Stock on the New York Stock Exchange, the International Managers and U.S. Underwriters have undertaken to sell lots of 100 or more shares to a minimum of 2,000 beneficial owners. The International Managers and U.S. Underwriters do not intend to confirm sales of the Class A Common Stock offered hereby to any accounts over which they exercise discretionary authority. CDW and the Selling Stockholders have agreed to indemnify the International Managers and the U.S. Underwriters against certain liabilities, including certain liabilities under the Securities Act, or to contribute to payments which the International Managers and U.S. Underwriters may be required to make in respect thereof. Until the distribution of the Class A Common Stock is completed, rules of the Commission may limit the ability of the Underwriters and certain selling group members to bid for and purchase the Class A Common Stock. As an exception to these rules, the U.S. Representatives are permitted to engage in certain transactions that stabilize the price of the Class A Common Stock. Such transactions consist of bids or purchases for the purpose of pegging, fixing or maintaining the price of the Class A Common Stock. If the Underwriters create a short position in the Class A Common Stock in connection with the Offerings, i.e., if they sell more shares of Class A Common Stock than are set forth on the cover page of this Prospectus, the U.S. Representatives may reduce that short position by purchasing Class A Common Stock in the open market. The U.S. Representatives may also elect to reduce any short position by exercising all or part of the over-allotment option described above. The U.S. Representatives may also impose a penalty bid on certain Underwriters and selling group members. This means that if the U.S. Representatives purchase shares of Class A Common Stock in the open market to reduce the Underwriters' short position or to stabilize the price of the Class A Common Stock, they may reclaim the amount of the selling concession from the Underwriters and selling group members who sold those shares as part of the Offerings. In general, purchases of a security for the purpose of stabilization or to reduce a short position could cause the price of the security to be higher than it might have been in the absence of such purchases. The imposition of a penalty bid might also have an effect on the price of the Class A Common Stock to the extent that it discourages resales of the Class A Common Stock. None of the Company, the Selling Stockholders or any of the Underwriters makes any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the Class A Common Stock. In addition, none of the Company, the Selling Stockholders or any of the Underwriters makes any representation that the U.S. Representatives will engage in such transactions or that such transactions, once commenced, will not be discontinued without notice. Each International Manager has agreed that (i) it has not offered or sold, and, for a period of six months from the Closing Date, will not offer or sell, to persons in the United Kingdom, other than to persons whose ordinary activities involve them in acquiring, holding, managing or disposing of investments (as principal or agent) for the purpose of their businesses or otherwise in circumstances which have not resulted and will not result in an offer to the public in the United Kingdom within the meaning of the Public Offers of Securities Regulations 1995; (ii) it has complied with and will comply with all applicable provisions of the Financial Services Act 1986 with respect to anything done by it in relation to the shares of Class A Common Stock in, 69

[ALTERNATE PAGE FOR INTERNATIONAL PROSPECTUS] from or otherwise involving the United Kingdom; and (iii) it has only issued or passed on and will only issue or pass on in the United Kingdom any document received by it in connection with the issue of shares of Class A Common Stock to a person who is of a kind described in Article 11(3) of the Financial Services Act 1986 (Investment Advertisements) (Exemptions) Order 1996, or is a person to whom such document may otherwise lawfully be issued or passed on. No action has been or will be taken in any jurisdiction (except in the United States) that would permit a public offering of the shares of Class A Common Stock, or the possession, circulation or distribution of this Prospectus or any other material relating to the Company or shares of Class A Common Stock in any jurisdiction where action for that purpose is required. Accordingly, the shares of Class A Common Stock may not be offered or sold, directly or indirectly, and neither this Prospectus nor any other offering material or advertisements in connection with the shares of Class A Common Stock may be distributed or published, in or from any country or jurisdiction except in compliance with any applicable rules and regulations of any such country or jurisdiction. Purchasers of the shares offered hereby may be required to pay stamp taxes and other charges in accordance with the laws and practices of the country of purchase in addition to the offering price set forth on the cover page hereof. 70

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS Section 145 of the General Corporation Law of the State of Delaware (the "Delaware Law") empowers a Delaware corporation to indemnify any persons who are, or are threatened to be made, parties to any threatened, pending or completed legal action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation), by reason of the fact that such person was an officer or director of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided that such officer or director acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the corporation's best interests, and, for criminal proceedings, had no reasonable cause to believe his conduct was illegal. A Delaware corporation may indemnify officers and directors in an action by or in the right of the corporation under the same conditions, except that no indemnification is permitted without judicial approval if the officer or director is adjudged to be liable to the corporation in the performance of his duty. Where an officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him against the expenses which such officer or director actually and reasonably incurred. Article VI of CDW's By-Laws provides for indemnification by CDW of its directors and officers to the full extent permitted by the Delaware Law. Pursuant to Section 145 of the Delaware Law, the Company has purchased insurance on behalf of its present and former directors and officers against any liability asserted against or incurred by them in such capacity or arising out of their status as such. Pursuant to specific authority granted by Section 102 of the Delaware Law, Article FIFTH of CDW's Third Restated Certificate of Incorporation contains the following provision regarding limitation of liability of directors and officers: "(e) No director of the Corporation shall be liable to the Corporation or its stockholders for monetary damages for breach of his or her fiduciary duty as a director, provided that nothing contained in this Third II-1

Restated Certificate of Incorporation shall eliminate or limit the liability of a director (i) for any breach of the director's duty of loyalty to the Corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law, (iii) under Section 174 of the General Corporation Law of the State of Delaware or (iv) for any transaction from which the director derived an improper personal benefit." CDW has entered into an Indemnification Agreement with Fund IV (together with its respective affiliates, directors and officers, the "Indemnitees"). Pursuant to the Indemnification Agreement, CDW has agreed to indemnify the members of its Board of Directors to the fullest extent allowable under applicable Delaware law. In addition, CDW has agreed to indemnify the Indemnitees against any suits, claims, damages or expenses that may be made against or incurred by them under applicable securities laws in connection with offerings of securities of CDW. However, CDW will not be obligated to indemnify any Indemnitee in the event that any such suit, claim, damage or expense is based upon an untrue statement or agreements related to such offerings of securities in reliance upon written information furnished by such Indemnitee specifically for use in such documents, contracts and agreements. See "Underwriting." Reference is hereby made to Section 2 of the Underwriting Agreement filed as Exhibit 1 hereto, for certain indemnification arrangements. ITEM 15.

ITEM 17. UNDERTAKINGS The undersigned registrant hereby undertakes to provide to the Underwriters at the closing specified in the Underwriting Agreement certificates in such denominations and registered in such names as required by the Underwriters to permit prompt delivery to each purchaser. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy II-4

as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue. The undersigned registrant hereby undertakes that: (1) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective. (2) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

The Company, the Selling Stockholders and the Underwriters agree that up to ____________shares of the Securities to be purchased by the Underwriters (the "Reserved Securities") shall be reserved for sale by the Underwriters to certain eligible employees and persons having business relationships with the Company, as part of the distribution of the Securities by the Underwriters, subject to the terms of this Agreement, the applicable rules, regulations and interpretations of the National Association of Securities Dealers, Inc. and all other applicable laws, rules and regulations.

The Company has filed with the Securities and Exchange Commission (the "Commission") a registration statement on Form S-1 (No. 333-___) covering the registration of the Securities under the Securities Act of 1933, as amended (the "1933 Act"), including the related preliminary prospectus or prospectuses. Promptly after execution and delivery of this Agreement, the Company will either (i) prepare and file a prospectus in accordance with the provisions of -2-

Rule 430A ("Rule 430A") of the rules and regulations of the Commission under the 1933 Act (the "1933 Act Regulations") and paragraph (b) of Rule 424 ("Rule 424(b)") of the 1933 Act Regulations or (ii) if the Company has elected to rely upon Rule 434 ("Rule 434") of the 1933 Act Regulations, prepare and file a term sheet (a "Term Sheet") in accordance with the provisions of Rule 434 and Rule 424(b). Two forms of prospectus are to be used in connection with the offering and sale of the Securities: one relating to the U.S. Securities (the "Form of U.S. Prospectus") and one relating to the International Securities (the "Form of International Prospectus"). The Form of International Prospectus is identical to the Form of U.S. Prospectus, except for the front cover and back cover pages and the information under the caption "Underwriting" and the inclusion in the Form of International Prospectus of a section under the caption "United States Federal Tax Considerations for Non-U.S. Holders." The information included in any such prospectus or in any such Term Sheet, as the case may be, that was omitted from such registration statement at the time it became effective but that is deemed to be part of such registration statement at the time it became effective (a) pursuant to paragraph (b) of Rule 430A is referred to as "Rule 430A Information" or (b) pursuant to paragraph (d) of Rule 434 is referred to as "Rule 434 Information." Each Form of U.S. Prospectus and Form of International Prospectus used before such registration statement became effective, and any prospectus that omitted, as applicable, the Rule 430A Information or the Rule 434 Information, that was used after such effectiveness and prior to the execution and delivery of this Agreement, is herein called a "preliminary prospectus." Such registration statement, including the exhibits thereto and schedules thereto at the time it became effective and including the Rule 430A Information and the Rule 434 Information, as applicable, is herein called the "Registration Statement." Any registration statement filed pursuant to Rule 462(b) of the 1933 Act Regulations is herein referred to as the "Rule 462(b) Registration Statement," and after such filing the term "Registration Statement" shall include the Rule 462(b) Registration Statement. The final Form of U.S. Prospectus and the final Form of International Prospectus in the forms first furnished to the Underwriters for use in connection with the offering of the Securities are herein called the "U.S. Prospectus" and the "International Prospectus," respectively, and collectively, the "Prospectuses." If Rule 434 is relied on, the terms "U.S. Prospectus" and "International Prospectus" shall refer to the preliminary U.S. Prospectus dated January __, 1998 and preliminary International Prospectus dated January __, 1998, respectively, each together with the applicable Term Sheet and all references in this Agreement to the date of such Prospectuses shall mean the date of the applicable Term Sheet. For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus, the U.S. Prospectus, the International Prospectus or any Term Sheet or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system ("EDGAR").

case of any condition to the purchase of U.S. Option Securities on a Date of Delivery which is after the Closing Time, the obligations of the several U.S. Underwriters to purchase the relevant Option Securities, may be terminated by the U.S. Representatives by notice to the Company at any time at or prior to Closing Time or such Date of Delivery, as the case may be, and such termination shall be without liability of any party to any other party except as provided in Section 4 and except that Sections 1, 6, 7 and 8 shall survive any such termination and remain in full force and effect. SECTION 6. Indemnification. --------------- (a) Indemnification of U.S. Underwriters. The Company and each of the Selling Stockholder, jointly and severally, agree to indemnify and hold harmless each U.S. Underwriter and each person, if any, who controls any U.S. Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows: (i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including the Rule 430A Information and the Rule 434 Information, if applicable, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any preliminary prospectus or the Prospectuses (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; (ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of (A) the violation of any applicable laws or regulations of foreign jurisdictions where Reserved Securities have been offered and (B) any untrue statement or alleged untrue statement of a material fact included in the supplement or prospectus wrapper material distributed in [ ] in connection with the reservation and sale of the Reserved Securities to [eligible employees and ________ of the Company] or the omission or alleged omission therefrom of a material fact necessary to make the statements therein, when considered in conjunction with the Prospectus or preliminary prospectus, not misleading; (iii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission or in connection with any violation of the nature referred to in Section 6(a)(ii)(A) hereof; provided that (subject to Section 6(d) below) any such settlement is effected with the written consent of the Company; and (iv) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by Merrill Lynch), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based -22-

upon any such untrue statement or omission, or any such alleged untrue statement or omission or in connection with any violation of the nature referred to in Section 6(a)(ii)(A) hereof, to the extent that any such expense is not paid under (i), (ii) or (iii) above; provided, however, that this indemnity agreement shall not apply to any loss, - -------- ------- liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any U.S. Underwriter through the U.S. Representatives expressly for use in the Registration Statement (or any amendment thereto), including the Rule 430A Information and the Rule 434 Information, if applicable, or any preliminary prospectus or the U.S. Prospectus (or any amendment or supplement thereto); provided, however, further, that with respect to each Selling Stockholder, (x) the indemnification provision in this paragraph (a) shall be only with respect to the information furnished in writing by or on behalf of such Selling Stockholder expressly for use in the Registration Statement (or any amendment thereto), including Rule 430A Information, if applicable, or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) and (y) such Selling Stockholder's aggregate liability under this Section 6 shall be limited to an amount equal to the net proceeds (after deducting the underwriting discount but before deducting expenses) received by such Selling Stockholder from the sale of Securities pursuant to this Agreement. (b) Indemnification of Company, Directors and Officers and Selling Stockholders. Each U.S. Underwriter severally agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and each Selling Shareholder and each person, if any, who controls any Selling Stockholder within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a)[(1)] of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), including the Rule 430A Information and the Rule 434 Information, if applicable, or any preliminary U.S. prospectus or the U.S. Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by such U.S. Underwriter through the U.S. Representatives expressly for use in the Registration Statement (or any amendment thereto) or such preliminary prospectus or the U.S. Prospectus (or any amendment or supplement thereto). (c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a) above, counsel to the indemnified parties shall be selected by Merrill Lynch, and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Company or the indemnified Selling Stockholder, as appropriate. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the -23-

indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. (d) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(iii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement. (e) Indemnification for Reserved Securities. In connection with the offer and sale of the Reserved Securities, the Company agrees, promptly upon a request in writing, to indemnify and hold harmless the Underwriters from and against any and all losses, liabilities, claims, damages and expenses incurred by them as a result of the failure of certain eligible employees and persons having business relationships with the Company to pay for and accept delivery of Reserved Securities which, by the end of the first business day following the date of this Agreement, were subject to a properly confirmed agreement to purchase. -24-

SECTION 7. Contribution. If the indemnification provided for in Section ------------ 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholders on the one hand and the U.S. Underwriters on the other hand from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Selling Stockholders on the one hand and of the U.S. Underwriters on the other hand in connection with the statements or omissions, or in connection with any violation of the nature referred to in Section 6(a)(ii)(A) hereof, which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Stockholders on the one hand and the U.S. Underwriters on the other hand in connection with the offering of the U.S. Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the U.S. Securities pursuant to this Agreement (before deducting expenses) received by the Selling Stockholders and the total underwriting discount received by the U.S. Underwriters, in each case as set forth on the cover of the U.S. Prospectus, or, if Rule 434 is used, the corresponding location on the Term Sheet, bear to the aggregate initial public offering price of the U.S. Securities as set forth on such cover. The relative fault of the Company and the Selling Stockholders on the one hand and the U.S. Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Selling Stockholders or by the U.S. Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or any violation of the nature referred to in Section 6(a)(ii)(A) hereof. The Company, the Selling Stockholders and the U.S. Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the U.S. Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission. Notwithstanding the provisions of this Section 7, no U.S. Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the U.S. Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such U.S. Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission. -25-

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 7, each person, if any, who controls a U.S. Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such U.S. Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The U.S. Underwriters' respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Initial U.S. Securities set forth opposite their respective names in Schedule A hereto and not joint. SECTION 8. Representations, Warranties and Agreements to Survive Delivery. -------------------------------------------------------------- All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or any of its Subsidiaries submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any U.S. Underwriter or controlling person, or by or on behalf of the Company, and shall survive delivery of the Securities to the U.S. Underwriters. SECTION 9. Termination of Agreement. ------------------------ (a) Termination; General. The U.S. Representatives may terminate this Agreement, by notice to the Company, at any time at or prior to Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the U.S. Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its Subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the U.S. Representatives, impracticable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the New York Stock Exchange, or if trading generally on the American Stock Exchange or the New York Stock Exchange or in the Nasdaq National Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the National Association of Securities Dealers, Inc. or any other governmental authority, or (iv) if a banking moratorium has been declared by either Federal or New York authorities. (b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7 and 8 shall survive such termination and remain in full force and effect. -26-

SECTION 10. Default by One or More of the U.S. Underwriters. If one or ----------------------------------------------- more of the U.S. Underwriters shall fail at Closing Time or a Date of Delivery to purchase the Securities which it or they are obligated to purchase under this Agreement (the "Defaulted Securities"), the U.S. Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting U.S. Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the U.S. Representatives shall not have completed such arrangements within such 24-hour period, then: (a) if the number of Defaulted Securities does not exceed 10% of the number of U.S. Securities to be purchased on such date, each of the non- defaulting U.S. Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting U.S. Underwriters, or (b) if the number of Defaulted Securities exceeds 10% of the number of U.S. Securities to be purchased on such date, this Agreement or, with respect to any Date of Delivery which occurs after the Closing Time, the obligation of the U.S. Underwriters to purchase and of the Company to sell the Option Securities to be purchased and sold on such Date of Delivery shall terminate without liability on the part of any non-defaulting U.S. Underwriter. No action taken pursuant to this Section shall relieve any defaulting U.S. Underwriter from liability in respect of its default. In the event of any such default which does not result in a termination of this Agreement or, in the case of a Date of Delivery which is after the Closing Time, which does not result in a termination of the obligation of the U.S. Underwriters to purchase and the Company to sell the relevant U.S. Option Securities, as the case may be, either the U.S. Representatives or the Company shall have the right to postpone Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements. As used herein, the term "U.S. Underwriter" includes any person substituted for a U.S. Underwriter under this Section 10. SECTION 11. Notices. All notices and other communications hereunder ------- shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.

Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the U.S. Underwriters, the Selling -27-

Stockholders and the Company and their respective successors and the controlling persons and officers and directors referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the U.S. Underwriters, the Selling Stockholders and the Company and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Securities from any U.S. Underwriter shall be deemed to be a successor by reason merely of such purchase. SECTION 13. GOVERNING LAW AND TIME. THIS AGREEMENT SHALL BE GOVERNED BY ---------------------- AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME. SECTION 14.

them pro rata according to the amounts offered by such Lenders (with appropriate --- ---- rounding, in the sole discretion of the Borrower, to assure that each accepted CAF Advance is an integral multiple of $1,000,000); provided that if the number -------- of Lenders that submit offers for any CAF Advance Maturity Date at identical pricing is such that, after the Borrower accepts such offers pro rata in --- ---- accordance with the foregoing provisions of this paragraph, the CAF Advance to be made by any such Lender would be less than $5,000,000 principal amount, the number of such Lenders shall be reduced by the Agent by lot until the CAF Advances to be made by each such remaining Lender would be in a principal amount of $5,000,000 or an integral multiple of $1,000,000 in excess thereof.

(b) The Borrower shall pay interest on the unpaid principal amount of each CAF Advance from the Borrowing Date to applicable CAF Advance Maturity Date at the rate of interest specified in the CAF Advance Offer accepted by the Borrower in connection with such CAF Advance (calculated on the basis of a 360-day year for actual days elapsed), payable on each applicable CAF Advance Interest Payment Date. (c) If any principal of, or interest on, any CAF Advance shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), such CAF Advance shall, without limiting any rights of any Lender under this Agreement, bear interest from the date on which such payment was due at a rate per annum which is 2% above the rate which would otherwise be applicable to such CAF Advance until the stated CAF Advance Maturity Date of such CAF Advance, and for each day thereafter at a rate per annum which is 2% above the ABR, in each case until paid in full (as well after as before judgment).

The proceeds of the Swing Line Loan will be made available by the Swing Line Lender to the Borrower at the office of the Swing Line Lender by crediting the account of the Borrower at such office with such proceeds in Dollars. 80

(ii) Provided that the conditions precedent contained in subsection 6.2 to its obligation to make a Swing Line Loan have been satisfied and that there is sufficient availability under the Swing Line Commitment, on each Interest Payment Date, the Swing Line Lender shall, on behalf of the Borrower (which hereby irrevocably authorizes and directs the Swing Line Lender to act on its behalf), make a Swing Line Loan to the Borrower in an amount equal to the amount of interest due and payable on such Interest Payment Date pursuant to subsection 4.1. The proceeds of such Swing Line Loan shall be made available by the Swing Line Lender to the Administrative Agent and applied by the Administrative Agent to the payment of such interest on such Interest Payment Date; the Swing Line Lender shall notify the Borrower as soon as reasonably practicable of the amount of each such Swing Line Loan. (b) The Swing Line Loans shall be evidenced by a promissory note of the Borrower substantially in the form of Exhibit A-2, with appropriate insertions (as the same may be amended, supplemented, replaced or otherwise modified from time to time, the "Swing Line Note"), payable to the order of the Swing Line --------------- Lender and representing the obligation of the Borrower to pay the amount of the Swing Line Commitment or, if less, the unpaid principal amount of the Swing Line Loans, with interest thereon as prescribed in subsection 4.1. The Swing Line Lender is hereby authorized to record the Borrowing Date, the amount of each Swing Line Loan and the date and amount of each payment or prepayment of principal thereof, on its internal books and records and/or on the schedule annexed to and constituting a part of the Swing Line Note and any such recordation on such schedule shall constitute prima facie evidence of the ----- ----- accuracy of the information so recorded, provided that the failure by the -------- Swing Line Lender to make any such recordation or any error in any such recordation shall not affect the obligations of the Borrower under this Agreement or the Swing Line Note. The Swing Line Note shall (a) be dated the Closing Date, (b) be stated to mature on the Termination Date and (c) provide 81

for the payment of interest in accordance with subsection 4.1. (c) The Swing Line Lender, at any time in its sole and absolute discretion may, and, at any time when Swing Line Loans are outstanding for more than seven Business Days, the Swing Line Lender shall, on behalf of the Borrower (which hereby irrevocably directs and authorizes the Swing Line Lender to act on its behalf), request each Lender to make a Revolving Credit Loan in an amount equal to such Lender's Commitment Percentage of the principal amount of the Swing Line Loans (the "Refunded Swing Line Loans") outstanding on the date such ------------------------- notice is given; provided that the provisions of this subsection shall not -------- affect the Borrower's obligations to prepay Swing Line Loans in accordance with the provisions of subsection 4.4(d). Unless the Commitments shall have expired or terminated (in which event the procedures of paragraph (d) of this subsection 2.10 shall apply), each Lender will make the proceeds of the Revolving Credit Loan made by it pursuant to the immediately preceding sentence available to the Administrative Agent for the account of the Swing Line Lender at the office of the Administrative Agent prior to 12:00 Noon, New York City time, in funds immediately available on the Business Day next succeeding the date such notice is given. The proceeds of such Revolving Credit Loans shall be immediately applied to repay the Refunded Swing Line Loans. (d) If the Commitments shall expire or terminate at any time while Swing Line Loans are outstanding, each Lender shall, at the option of the Swing Line Lender exercised reasonably, either (i) notwithstanding the expiration or termination of the Commitments, make a Revolving Credit Loan or (ii) purchase an undivided participating interest in such Swing Line Loans, in either case in an amount equal to such Lender's Commitment Percentage determined on the date of, and immediately prior to, expiration or termination of the Commitments of the aggregate principal amount of such Swing Line Loans. Each Lender will make the proceeds of any Revolving Credit Loan 82

made by it pursuant to the immediately preceding sentence available to the Administrative Agent for the account of the Swing Line Lender at the office of the Administrative Agent prior to 12:00 Noon, New York City time, in funds immediately available on the Business Day next succeeding the date on which the Commitments expire or terminate. The proceeds of such Revolving Credit Loans shall be immediately applied to repay the Swing Line Loans outstanding on the date of termination or expiration of the Commitments. In the event that the Lenders purchase undivided participating interests pursuant to the first sentence of this paragraph (d), each Lender shall immediately transfer to the Swing Line Lender, in immediately available funds, the amount of its participation and upon receipt thereof the Swing Line Lender will deliver to any such Lender that so requests a confirmation of such Lender's undivided participating interest in the Swing Line Loans dated the date of receipt of such funds and in such amount. (e) Whenever, at any time after the Swing Line Lender has received from any Lender such Lender's participating interest in a Swing Line Loan, the Swing Line Lender receives any payment on account thereof, the Swing Line Lender will distribute to such Lender its participating interest in such amount (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender's participating interest was outstanding and funded); provided, however, that in the event that such payment received by the -------- ------- Swing Line Lender is required to be returned, such Lender will return to the Swing Line Lender any portion thereof previously distributed by the Swing Line Lender to it. SECTION 3. LETTERS OF CREDIT 3.1. L/C Commitment. (a) Subject to the terms and conditions hereof, the -------------- Issuing Lender, in reliance on the agreements of the other Lenders set forth in subsection 3.4(a), agrees to issue letters of credit ("Letters of ----------- 83

Credit") for the account of the Borrower on any Business Day during the - ------ Commitment Period in such form as may be approved from time to time by the Issuing Lender; provided that the Issuing Lender shall have no obligation to -------- issue any Letter of Credit if, after giving effect to such issuance, (i) the L/C Obligations would exceed the L/C Commitment or (ii) the Total Aggregate Outstandings would exceed the lesser of (x) the aggregate Commitments and (y) the Borrowing Base then in effect. Each Letter of Credit shall (i) be denominated in Dollars and shall be either (x) a standby letter of credit issued to support obligations of the Borrower or any of its Additional Subsidiaries, contingent or otherwise, which finance the working capital and business needs of the Borrower and its Additional Subsidiaries incurred in the ordinary course of business (the "Standby Letters of Credit"), or (y) a ------------------------- commercial letter of credit in respect of the purchase of goods or services by the Borrower or any of its Additional Subsidiaries in the ordinary course of business (the "Commercial Letters of Credit"), (ii) expire no later than five ---------------------------- Business Days prior to the Termination Date, and (iii) expire no later than 365 days after its date of issuance. (b) Each Letter of Credit shall be subject to the Uniform Customs and, to the extent not inconsistent therewith, the laws of the State of New York. (c) The Issuing Lender shall not at any time be obligated to issue any Letter of Credit hereunder if such issuance would conflict with, or cause the Issuing Lender or any L/C Participant to exceed any limits imposed by, any applicable Requirement of Law. 3.2 Procedure for Issuance of Letters of Credit. The Borrower may from ------------------------------------------- time to time request that the Issuing Lender issue a Letter of Credit by delivering to the Issuing Lender, at its address for notices specified herein, an Application therefor, completed to the reasonable satisfaction of the Issuing Lender, and such other certificates, documents and other papers and information as 84

the Issuing Lender may reasonably request. Upon receipt of any Application, the Issuing Lender will process such Application and the certificates, documents and other papers and information delivered to it in connection therewith in accordance with its customary procedures and shall promptly issue the Letter of Credit requested thereby (but in no event shall the Issuing Lender be required to issue any Letter of Credit earlier than three Business Days after its receipt of the Application therefor and all such other certificates, documents and other papers and information relating thereto) by issuing the original of such Letter of Credit to the beneficiary thereof or as otherwise may be agreed by the Issuing Lender and the Borrower. The Issuing Lender shall furnish a copy of such Letter of Credit to the Borrower promptly following the issuance thereof. 3.3 Fees, Commissions and Other Charges. The Borrower shall pay to the ----------------------------------- Administrative Agent, for the account of the Issuing Lender and the L/C Participants, a letter of credit commission with respect to each Letter of Credit, for the period from and including the date of issuance of such Letter of Credit to the expiration date of such Letter of Credit, computed at the L/C Commission Rate, calculated on the basis of a 365- (or 366-, as the case may be) day year, on the aggregate amount available to be drawn under such Letter of Credit, payable quarterly in arrears on each L/C Fee Payment Date to occur during such period and on the expiration date of such Letter of Credit. Such commissions shall be payable to the Lenders to be shared ratably among them in accordance with their respective Commitment Percentages. In addition, the Borrower shall pay to the Administrative Agent, for the account of the Issuing Bank, a fronting fee with respect to each Letter of Credit, for the period from and including the date of issuance of such Letter of Credit to the expiration date of such Letter of Credit, computed at a rate of 1/8 of 1% per annum, calculated on the basis of a 365- (or 366-, as the case may be) day year, on the product of (i) the aggregate of the Commitment Percentages of the L/C Participants multiplied by (ii) the aggregate amount available to be drawn under such 85

Letter of Credit, payable quarterly in arrears on each L/C Fee Payment Date to occur during such period and on the expiration date of such Letter of Credit. Such fees and commissions shall be nonrefundable. (b) In addition to the foregoing fees and commissions, the Borrower shall pay or reimburse the Issuing Lender for such normal and customary costs and expenses as are incurred or charged by the Issuing Lender in issuing, effecting payment under, amending or otherwise administering any Letter of Credit. (c) The Administrative Agent shall, promptly following its receipt thereof, distribute to the Issuing Lender and the L/C Participants all fees and commissions received by the Administrative Agent for their respective accounts pursuant to this subsection. 3.4 L/C Participations. (a) The Issuing Lender irrevocably agrees to ------------------ grant and hereby grants to each L/C Participant, and, to induce the Issuing Lender to issue Letters of Credit hereunder, each L/C Participant irrevocably agrees to accept and purchase and hereby accepts and purchases from the Issuing Lender, on the terms and conditions hereinafter stated, for such L/C Participant's own account and risk an undivided interest equal to such L/C Participant's Commitment Percentage (as in effect from time to time) in the Issuing Lender's obligations and rights under each Letter of Credit and the amount of each draft paid by the Issuing Lender thereunder. Each L/C Participant unconditionally and irrevocably agrees with the Issuing Lender that, if a draft is paid under any Letter of Credit for which the Issuing Lender is not reimbursed in full by the Borrower in accordance with subsection 3.5(a), such L/C Participant shall pay to the Issuing Lender at the Issuing Lender's address for notices specified herein an amount equal to such L/C Participant's Commitment Percentage (in effect on the date of such demand) of the amount of such draft, or any part thereof, which is not so reimbursed, such payment to be made by such L/C Participant on the date 86

(which shall be a Business Day) a demand therefor is made by the Issuing Lender (if such demand is made prior to 12:00 P.M., New York City time on such date) or on the next Business Day (if such demand is made after 12:00 P.M., New York City time on such date). (b) If any amount required to be paid by any L/C Participant to the Issuing Lender pursuant to subsection 3.4(a) in respect of any unreimbursed portion of any payment made by the Issuing Lender under any Letter of Credit is paid to the Issuing Lender within three Business Days after the date such payment is due, such L/C Participant shall pay to the Issuing Lender on demand an amount equal to the product of such amount, times the daily average Federal Funds Effective Rate, as quoted by the Issuing Lender, during the period from and including the date such payment is required to the date on which such payment is immediately available to the Issuing Lender, times a fraction the numerator of which is the number of days that elapse during such period and the denominator of which is 360. If any such amount required to be paid by any L/C Participant pursuant to subsection 3.4(a) is not in fact made available to the Issuing Lender by such L/C Participant within three Business Days after the date such payment is due, the Issuing Lender shall be entitled to recover from such L/C Participant, on demand, such amount with interest thereon calculated from such due date at the rate per annum applicable to Base Rate Loans hereunder. A certificate of the Issuing Lender submitted to any L/C Participant with respect to any amounts owing under this subsection shall be conclusive in the absence of manifest error. (c) Whenever, at any time after the Issuing Lender has made payment under any Letter of Credit and has received from any L/C Participant its pro rata --- ---- share of such payment in accordance with subsection 3.4 (a), the Issuing Lender receives any payment related to such Letter of Credit (whether directly from the Borrower or otherwise, including proceeds of Collateral applied thereto by the Issuing Lender), or any payment of interest on account thereof, the 87

Issuing Lender will, if such payment is received prior to 12:00 Noon, New York City time, on a Business Day, distribute to such L/C Participant its pro rata --- ---- share thereof prior to the end of such Business Day and otherwise the Issuing Lender will distribute such payment on the next succeeding Business Day; provided, however, that in the event that any such payment received by the - -------- ------- Issuing Lender shall be required to be returned by the Issuing Lender, such L/C Participant shall return to the Issuing Lender the portion thereof previously distributed by the Issuing Lender to it. 3.5 Reimbursement Obligation of the Borrower. (a) The Borrower agrees to ---------------------------------------- reimburse the Issuing Lender, upon receipt of notice from the Issuing Lender of the date and amount of a draft presented under any Letter of Credit and paid by the Issuing Lender, for the amount of such draft so paid and any taxes, fees, charges or other costs or expenses incurred by the Issuing Lender in connection with such payment. Except as and to the extent otherwise provided in subsection 3.5(c), each such payment shall be made to the Issuing Lender, at its address for notices specified herein in Dollars and in immediately available funds, on the date on which the Borrower receives such notice, if received prior to 11:00 A.M., New York City time, on a Business Day and otherwise on the next succeeding Business Day. (b) Interest shall be payable on any and all amounts payable under subsection 3.5(a) and remaining unpaid by the Borrower (i) from the date the draft presented under the affected Letter of Credit is paid to the earlier of the third Business Day after the date on which the Borrower is required to pay such amounts pursuant to subsection 3.5(a) and the date on which the Borrower pays all such amounts at the rate which would then be payable on any outstanding Base Rate Loans and (ii) thereafter until payment in full at the rate which would be payable on any outstanding Base Rate Loans which were then overdue. 88

(c) By 12:00 P.M., New York City time, on the first Business Day after each date on which a draft is presented under any Letter of Credit and paid by the Issuing Lender, the Administrative Agent shall, on behalf of the Borrower (which hereby irrevocably directs and authorizes the Administrative Agent to act on its behalf), request (in accordance with the applicable provisions of subsection 2.3) each Lender to make a Revolving Credit Loan (which shall be a Base Rate Loan) in an amount equal to such Lender's Commitment Percentage of the amount of such draft so paid. Each Lender agrees to make each Revolving Credit Loan so requested available to the Administrative Agent in accordance with subsection 2.3, provided that the conditions precedent contained in subsections -------- 2.1 and 6.2 to its obligation to make such Revolving Credit Loan have been satisfied. The proceeds of such Revolving Credit Loans shall be made available by the Administrative Agent to the Issuing Lender and applied to the payment (whether or not then due) of the obligations of the Borrower under subsection 3.5(a)(i); upon such payment, the Borrower shall be deemed to have satisfied such obligations to the extent of such payment. The Issuing Lender shall notify the Administrative Agent and the Borrower as soon as reasonably practicable of each drawing made under a Letter of Credit and the aggregate principal amount of the Revolving Credit Loans made under this subsection 3.5(c) in respect thereof. (3.6) Obligations Absolute. (a) The Borrower's obligations under this -------------------- Section 3 shall be absolute and unconditional under any and all circumstances and irrespective of any set-off, counterclaim or defense to payment which the Borrower may have or have had against the Issuing Lender or any beneficiary of a Letter of Credit, provided, that this paragraph shall not relieve the Issuing -------- Lender of any liability resulting from the gross negligence or willful misconduct of the Issuing Lender, or otherwise affect any defense or other right that the Borrower may have as a result of any such gross negligence or willful misconduct. 89

(b) The Borrower also agrees with the Issuing Lender that the Issuing Lender shall not be responsible for, and the Borrower's Reimbursement Obligations under subsection 3.5(a) shall not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even though such documents shall in fact prove to be invalid, fraudulent or forged, or any dispute between or among the Borrower and any beneficiary of any Letter of Credit or any other party to which such Letter of Credit may be transferred or any claims whatsoever of the Borrower against any beneficiary of such Letter of Credit or any such transferee, provided that this paragraph -------- shall not relieve the Issuing Lender of any liability resulting from the gross negligence or willful misconduct of the Issuing Lender, or otherwise affect any defense or other right that the Borrower may have as a result of any such gross negligence or willful misconduct. (c) The Issuing Lender shall not be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit, except for errors or omissions caused by the Issuing Lender's gross negligence or willful misconduct. (d) The Borrower agrees that any action taken or omitted by the Issuing Lender under or in connection with any Letter of Credit or the related drafts or documents, if done in the absence of gross negligence or willful misconduct and in accordance with the standards of care specified in the Uniform Commercial Code of the State of New York, shall be binding on the Borrower and shall not result in any liability of the Issuing Lender to the Borrower. 3.7 Letter of Credit Payments. If any draft shall be presented for ------------------------- payment under any Letter of Credit, the Issuing Lender shall promptly notify the Borrower and the Administrative Agent of the date and amount thereof. The responsibility of the Issuing Lender to the Borrower in connection with any draft presented for payment under any 90

Letter of Credit shall, in addition to any payment obligation expressly provided for in such Letter of Credit, be limited to determining that the documents (including each draft) delivered under such Letter of Credit in connection with such presentment are in conformity with such Letter of Credit, provided, that -------- this paragraph shall not relieve the Issuing Lender of any liability resulting from the gross negligence or willful misconduct of the Issuing Lender, or otherwise affect any defense or other right that the Borrower may have as a result of any such gross negligence or willful misconduct. 3.8 Application. To the extent that any provision of any Application ----------- related to any Letter of Credit is inconsistent with the provisions of this Section 3, the provisions of this Section 3 shall apply. SECTION 4. GENERAL PROVISIONS APPLICABLE TO LOANS AND LETTERS OF CREDIT 4.1 Interest Rates and Payment Dates. (a) Each Eurodollar Loan shall -------------------------------- bear interest for each day during each Interest Period with respect thereto at a rate per annum equal to the Eurodollar Rate determined for such day plus the Applicable Margin in effect for such day.

(ii) Unless otherwise agreed in writing by the Majority Lenders, if at any time the Borrower or any of its Subsidiaries (other than the Canadian Borrower or any of its Subsidiaries) shall make an Asset Sale pursuant to subsection 8.6(g), the Borrower shall repay the Revolving Credit Loans and the Swing Line Loans and any then outstanding Reimbursement Obligations in an aggregate amount equal to 100% of the Net Cash Proceeds thereof, together with accrued interest on such Loans and Reimbursement Obligations to the date of such payment and any amounts payable under subsection 4.13, such payments to be made promptly upon the receipt of such Net Cash Proceeds and to be applied to the Extensions of Credit in the same order as that specified in subsection 4.4(b).

day of each March, June, September and December and on the Termination Date or such earlier date as the Commitments shall terminate as provided herein, commencing on the first such date to occur after the date hereof. (b) The Borrower shall pay (without duplication of any fee payable under subsection 4.5(a)) to the Administrative Agent and the Collateral Agent, for their respective accounts, the other fees required to be paid pursuant to the Agency Fee Letter, dated February 24, 1995, between the Administrative Agent, the Collateral Agent and the Borrower, in each case in the amounts and on the dates set forth therein. (c) The Borrower shall pay to the Administrative Agent fees related to the operation of the CAF in such amounts upon which they shall mutually agree. 4.6 Computation of Interest and Fees. (a) Interest based on the -------------------------------- Eurodollar Rate shall be calculated on the basis of a 360-day year for the actual days elapsed; and facility fees and interest (other than interest based upon the Eurodollar Rate) shall be calculated on the basis of a 365- (or 366-, as the case may be) day year for the actual days elapsed. The Administrative Agent shall as soon as practicable notify the Borrower and the Lenders of each determination of a Eurodollar Rate. Any change in the interest rate on a Loan resulting from a change in the Base Rate or the Eurocurrency Reserve Requirements shall become effective as of the opening of business on the day on which such change becomes effective. The Administrative Agent shall as soon as practicable notify the Borrower and the Lenders of the effective date and the amount of each such change in interest rate. (b) Each determination of an interest rate by the Administrative Agent pursuant to any provision of this Agreement shall be conclusive and binding on the Borrower and the Lenders in the absence of manifest error.

If prior to the first day of ------------------------------------ any Interest Period, the Administrative Agent shall have determined (which determination shall be conclusive and binding upon the Borrower) that, by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the Eurodollar Rate for such Interest Period, the Administrative Agent shall give telecopy or telephonic notice thereof to the Borrower and the Lenders as soon as practicable thereafter. If such notice is given (x) any Eurodollar Loans requested to be made on the first day of such Interest Period shall be made as Base Rate Loans and (y) any Loans that were to have been converted on the first day of such Interest Period to or continued as Eurodollar Loans shall be converted to or continued as Base Rate Loans. Until such notice has been withdrawn by the Administrative Agent, no further Eurodollar Loans shall be made or continued as such, nor shall the Borrower have the right to convert Base Rate Loans to Eurodollar Loans. 4.8 Pro Rata Treatment and Payments. (a) Except as provided in ------------------------------- subsection 2.9(b) and (c), each borrowing of Loans (other than Swing Line Loans and CAF Advances) by the Borrower from the Lenders hereunder shall be made, each payment by the Borrower on account of any facility fee hereunder shall be allocated by the Administrative Agent, and any reduction of the Commitments of the Lenders shall be allocated by the Administrative Agent, pro rata according --- ---- to the relevant Commitment Percentages of the Lenders. Except as provided in subsection 2.9(c), each payment (including each prepayment) by the Borrower on account of principal of and interest on any Revolving Credit Loans shall be allocated by the Administrative Agent pro rata according to --- ---- 98

the respective outstanding principal amounts of such Revolving Credit Loans then held by the Lenders. All payments (including prepayments) to be made by the Borrower hereunder and under any Notes, whether on account of principal, interest, fees or otherwise, shall be made without set-off or counterclaim and shall be made prior to 1:00 P.M., New York City time, on the due date thereof to the Administrative Agent, for the account of the Lenders holding such Notes, at the Administrative Agent's office specified in subsection 11.2, in Dollars and in immediately available funds. The Administrative Agent shall distribute such payments to such Lenders, if any such payment is received prior to 12:00 Noon, New York City time, on a Business Day, in like funds as received prior to the end of such Business Day, and otherwise the Administrative Agent shall distribute such payment to such Lenders on the next succeeding Business Day. If any payment hereunder (other than payments on the Eurodollar Loans) becomes due and payable on a day other than a Business Day, the maturity of such payment shall be extended to the next succeeding Business Day, and, with respect to payments of principal, interest thereon shall be payable at the then applicable rate during such extension. If any payment on a Eurodollar Loan becomes due and payable on a day other than a Business Day, the maturity of such payment shall be extended to the next succeeding Business Day (and, with respect to payments of principal, interest thereon shall be payable at the then applicable rate during such extension) unless the result of such extension would be to extend such payment into another calendar month, in which event such payment shall be made on the immediately preceding Business Day. (b) Unless the Administrative Agent shall have been notified in writing by any Lender prior to a borrowing that such Lender will not make the amount that would constitute its share of such borrowing available to the Administrative Agent, the Administrative Agent may assume that such Lender is making such amount available to the Administrative Agent, and the Administrative Agent may, in reliance upon such assumption, make available to the 99

Borrower a corresponding amount. If such amount is not made available to the Administrative Agent by the required time on the Borrowing Date therefor, such Lender shall pay to the Administrative Agent, on demand, such amount with interest thereon at a rate per annum equal to the daily average Federal Funds Effective Rate for the period until such Lender makes such amount immediately available to the Administrative Agent. A certificate of the Administrative Agent submitted to any Lender with respect to any amounts owing under this subsection shall be conclusive in the absence of manifest error. If such Lender's share of such borrowing is not made available to the Administrative Agent by such Lender within three Business Days of such Borrowing Date, (x) the Administrative Agent shall notify the Borrower of the failure of such Lender to make such amount available to the Administrative Agent and the Administrative Agent shall also be entitled to recover such amount with interest thereon at the rate per annum applicable to Base Rate Loans hereunder, on demand, from the Borrower and (y) the Borrower may, without waiving any rights it may have against such Lender, borrow a like amount on an unsecured basis from any commercial bank for a period ending on the date upon which such Lender does in fact make such borrowing available, provided that (i) at the time such borrowing is made and at all times -------- while such amount is outstanding the Borrower would be permitted to borrow such amount pursuant to subsection 2.1 of this Agreement and (ii) the commercial bank from whom such borrowing is made waives in a written agreement reasonably satisfactory to the Administrative Agent any right of set-off it may have against the Collateral. 4.9 Borrowing Base Compliance. The Collateral Agent or another financial ------------------------- institution satisfactory to the Collateral Agent (including any Affiliate of the Collateral Agent) shall, from time to time during the Commitment Period (except during any Borrowing Base Elimination Period), review and confirm the information set forth in each Monthly Borrowing Base Certificate delivered by the Borrower in order to determine whether, at such time, the Borrower is in 100

compliance with the requirements in respect of the Borrowing Base under this Agreement, and the Borrower shall reimburse the Collateral Agent for its reasonable out-of-pocket expenses (excluding fees) in respect thereof. If the Borrower is not in compliance with such requirements, the Collateral Agent shall promptly notify the Borrower, the Administrative Agent and the Lenders of such noncompliance, and the Borrower shall make all mandatory prepayments required pursuant to subsection 4.4(b). 4.10 Illegality. Notwithstanding any other provision herein, if the ---------- adoption of or any change in any Requirement of Law or in the interpretation or application thereof occurring after the date hereof shall make it unlawful for any Lender to make or maintain Eurodollar Loans as contemplated by this Agreement, (a) such Lender shall as soon as reasonably practicable thereafter give written notice of such circumstances to the Borrower and the Administrative Agent (which notice shall be withdrawn whenever such circumstances no longer exist), (b) the commitment of such Lender hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and convert Base Rate Loans to Eurodollar Loans shall forthwith be cancelled, and, until such time as it shall no longer be unlawful for such Lender to make or maintain Eurodollar Loans, such Lender shall then have a commitment only to make a Base Rate Loan when a Eurodollar Loan is requested and (c) such Lender's Loans then outstanding as Eurodollar Loans, if any, shall be converted automatically to Base Rate Loans on the respective last days of the then current Interest Periods with respect to such Eurodollar Loans or within such earlier period as required by law. If any such conversion of a Eurodollar Loan occurs on a day which is not the last day of the then current Interest Period with respect thereto, the Borrower shall pay to such Lender such amounts, if any, as may be required pursuant to subsection 4.13. 4.11 Requirements of Law. (a) If the adoption of or any change in any ------------------- Requirement of Law or in the interpretation or application thereof applicable to any 101

Lender, or compliance by any Lender with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority, in each case made subsequent to the date hereof (or, if later, the date on which such Lender becomes a Lender): (i) shall subject such Lender to any tax of any kind whatsoever with respect to this Agreement, any Note, any Letter of Credit, any Application, any CAF Advance or any Eurodollar Loans made by it or its obligation to make Eurodollar Loans, or change the basis of taxation of payments to such Lender in respect thereof (except for Non-Excluded Taxes covered by subsection 4.12 (including Non-Excluded Taxes imposed solely by reason of any failure of such Lender to comply with its obligations under subsection 4.12(b)) and changes in rate of tax on the overall net income, or franchise tax (imposed in lieu of such net income tax), of such Lender or its applicable lending office, branch, or any affiliate thereof); (ii) shall impose, modify or hold applicable any reserve, special deposit, compulsory loan or similar requirement against assets held by, deposits or other liabilities in or for the account of, advances, loans or other extensions of credit by, or any other acquisition of funds by, any office of such Lender which is not otherwise included in the determination of the Eurodollar Rate hereunder; or (iii) shall impose on such Lender any other condition (excluding any tax of any kind whatsoever); and the result of any of the foregoing is to increase the cost to such Lender, by an amount which such Lender deems to be material, of making, converting into, continuing or maintaining Eurodollar Loans, maintaining Eurodollar Rate CAF Advances or issuing or participating in Letters of Credit or to reduce any amount receivable hereunder in respect thereof, then, in any such case, upon notice to the 102

Borrower from such Lender, through the Administrative Agent, in accordance herewith, the Borrower shall promptly pay such Lender, upon its demand, any additional amounts necessary to compensate such Lender for such increased cost or reduced amount receivable, provided that, in any such case, the Borrower -------- may elect to convert the Eurodollar Loans or Eurodollar Rate CAF Advances made by such Lender hereunder to Base Rate Loans by giving the Administrative Agent at least one Business Day's notice of such election, in which case the Borrower shall promptly pay to such Lender, upon demand, without duplication, such amounts, if any, as may be required pursuant to subsection 4.13. If any Lender becomes entitled to claim any additional amounts pursuant to this subsection, it shall as soon as reasonably practicable thereafter provide notice thereof to the Borrower, through the Administrative Agent, certifying (x) that one of the events described in this paragraph (a) has occurred and describing in reasonable detail the nature of such event, (y) as to the increased cost or reduced amount resulting from such event and (z) as to the additional amount demanded by such Lender and a reasonably detailed explanation of the calculation thereof. Such a certificate as to any additional amounts payable pursuant to this subsection submitted by such Lender, through the Administrative Agent, to the Borrower shall be conclusive in the absence of manifest error. This covenant shall survive the termination of this Agreement and the payment of the Notes and all other amounts payable hereunder. (b) If any Lender shall have determined that the adoption of or any change in any Requirement of Law regarding capital adequacy or in the interpretation or application thereof or compliance by such Lender or any corporation controlling such Lender with any request or directive regarding capital adequacy (whether or not having the force of law) from any Governmental Authority, in each case, made subsequent to the date hereof (or, if later, the date on which such Lender becomes a Lender), does or shall have the effect of reducing the rate of return on such Lender's or such corporation's capital as a consequence of 103

its obligations hereunder or under any Letter of Credit to a level below that which such Lender or such corporation could have achieved but for such change or compliance (taking into consideration such Lender's or such corporation's policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, within ten Business Days after submission by such Lender to the Borrower (with a copy to the Administrative Agent) of a written request therefor certifying (x) that one of the events described in this paragraph (b) has occurred and describing in reasonable detail the nature of such event, (y) as to the reduction of the rate of return on capital resulting from such event and (z) as to the additional amount or amounts demanded by such Lender and a reasonably detailed explanation of the calculation thereof, the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender for such reduction. 4.12 Taxes. (a) Except as provided below in this subsection, all payments ----- made by the Borrower under this Agreement, the Notes and the CAF Advances shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any Governmental Authority, excluding in the case of each Lender or its applicable lending office, or any branch or affiliate thereof (i) net income taxes, franchise taxes, branch taxes or taxes on the overall capital or net worth of any Lender or its applicable lending office, or any branch or affiliate thereof imposed by any jurisdiction under the laws of which such Lender, applicable lending office, branch or affiliate is organized or is located, or in which its principal executive office is located, or any nation within which such jurisdiction is located or any political subdivision thereof and (ii) any such taxes or other tax, levy, impost, duty, charge, fee, deduction or withholding imposed by reason of any connection between the jurisdiction imposing such tax and such Lender, applicable lending office, branch or affiliate other than a 104

connection arising solely from such Lender having executed, delivered or performed its obligations, or received payment under or enforced, this Agreement or the Notes. If any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or withholdings ("Non-Excluded Taxes") are required to be ------------------ withheld from any amounts payable to the Administrative Agent or any Lender hereunder or under the Notes the amounts so payable to the Administrative Agent or such Lender shall be increased to the extent necessary to yield to the Administrative Agent or such Lender (after payment of all Non-Excluded Taxes, including Non-Excluded Taxes on the amount of such increase), interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement and the Notes, provided, however, that the Borrower shall be ----------------- entitled to deduct and withhold any Non-Excluded Taxes and shall not be required to increase any such amounts payable to any Lender that is not organized under the laws of the United States of America or a state thereof if such Lender fails to comply with the requirements of paragraph (b) of this subsection. Whenever any Non-Excluded Taxes are payable by the Borrower, as promptly as possible thereafter the Borrower shall send to the Administrative Agent for its own account or for the account of such Lender, as the case may be, a certified copy of an original official receipt received by the Borrower showing payment thereof. If the Borrower fails to pay any Non-Excluded Taxes when due to the appropriate taxing authority or fails to remit to the Administrative Agent the required receipts or other required documentary evidence, the Borrower shall indemnify the Administrative Agent and the Lenders for any incremental taxes, interest or penalties that may become payable by the Administrative Agent or any Lender as a result of any such failure. The agreements in this subsection shall survive the termination of this Agreement and the payment of the Notes and all other amounts payable hereunder. (b) Each Lender that is not incorporated under the laws of the United States of America or a state thereof shall: 105

(X) (i) on or before the date of any payment by the Borrower under this Agreement or the Notes to such Lender, deliver to the Borrower and the Administrative Agent (A) two duly completed copies of United States Internal Revenue Service Form 1001 or 4224, or successor applicable form or documentation, as the case may be, certifying that it is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes and (B) an Internal Revenue Service Form W-8 or W-9, or successor applicable form or documentation, as the case may be, certifying that it is entitled to an exemption from United States backup withholding tax; (ii) deliver to the Borrower and the Administrative Agent two further copies of any such form or certification on or before the date that any such form or certification expires or becomes obsolete and after the occurrence of any event requiring a change in the most recent form previously delivered by it to the Borrower; and (iii) obtain such extensions of time for filing and complete such forms or certifications as may reasonably be requested by the Borrower or the Administrative Agent; or (Y) in the case of any such Lender that is not a "bank" within the meaning of Section 881(c)(3)(A) of the Code, (i) represent to the Borrower (for the benefit of the Borrower and the Administrative Agent) that it is not a bank within the meaning of Section 881(c)(3)(A) of the Code, (ii) agree to furnish to the Borrower on or before the date of any payment by the Borrower, with a copy to the Administrative Agent, (A) a certificate substantially in the form of Exhibit B hereto (any such certificate a "U.S. Tax Compliance Certificate" and (B) two ------------------------------- accurate and complete original signed copies of Internal Revenue Service Form W-8, or successor applicable form or documentation certifying 106

to such Lender's legal entitlement at the date of such certificate to an exemption from U.S. withholding tax under the provisions of Section 881(c) of the Code with respect to payments to be made under this Agreement (and to deliver to the Borrower and the Administrative Agent two further copies of such form on or before the date it expires or becomes obsolete and after the occurrence of any event requiring a change in the most recently provided form or documentation and, if necessary, obtain any extensions of time reasonably requested by the Borrower or the Administrative Agent for filing and completing such forms), and (iii) agree, to the extent legally entitled to do so, upon reasonable request by the Borrower, to provide to the Borrower (for the benefit of the Borrower and the Administrative Agent) such other forms or documentation as may be reasonably required in order to establish the legal entitlement of such Lender to an exemption from withholding with respect to payments under this Agreement; unless in any such case any change in treaty, law or regulation has occurred after the date such Person becomes a Lender hereunder which renders all such forms or documentation inapplicable or which would prevent such Lender from duly completing and delivering any such form or documentation with respect to it and such Lender so advises the Borrower and the Administrative Agent. Each Person that shall become a Lender or a Participant pursuant to subsection 11.6 shall, upon the effectiveness of the related transfer, be required to provide all of the forms, documentation, certifications and statements required pursuant to this subsection, provided that in the case of a Participant the obligations of -------- such Participant pursuant to this subsection (b) shall be determined as if the Participant were a Lender except that such Participant shall furnish all such required forms, certifications and statements to the Lender from which the related participation shall have been purchased. 107

4.13 Indemnity. The Borrower agrees to indemnify each Lender and to hold --------- each Lender harmless from any loss or expense which such Lender may sustain or incur (other than through such Lender's gross negligence or willful misconduct) as a consequence of (a) default by the Borrower in making a borrowing of, conversion into or continuation of Eurodollar Loans after the Borrower has given a notice requesting the same in accordance with the provisions of this Agreement, (b) default by the Borrower in making any payment of a Eurodollar Loan after the Borrower has given a notice thereof in accordance with the provisions of this Agreement or (c) the making of a payment of Eurodollar Loans on a day which is not the last day of an Interest Period with respect thereto. Such indemnification may include an amount equal to the excess, if any, of (i) the amount of interest which would have accrued on the amount so paid, or not so borrowed, converted or continued, for the period from the date of such payment or of such failure to borrow, convert or continue to the last day of the applicable Interest Period (or, in the case of a failure to borrow, convert or continue, the Interest Period that would have commenced on the date of such failure) in each case at the applicable rate of interest for such Eurodollar Loans provided for herein (excluding, however, the Applicable Margin included therein, if any) over (ii) the amount of interest (as reasonably determined by such Lender) which would have accrued to such Lender on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank eurodollar market. This covenant shall survive the termination of this Agreement and the payment of the Notes and all other amounts payable hereunder. 4.14 Certain Rules Relating to the Payment of Additional Amounts. (a) Upon ----------------------------------------------------------- the request, and at the expense, of the Borrower, each Lender to which the Borrower is required to pay any additional amount pursuant to subsection 4.11 or 4.12, and any Participant in respect of whose participation such payment is required, shall reasonably afford the Borrower the opportunity to contest, 108

and reasonably cooperate with the Borrower in contesting, the imposition of any Non-Excluded Tax giving rise to such payment; provided that (i) such Lender -------- shall not be required to afford the Borrower the opportunity to so contest unless the Borrower shall have confirmed in writing to such Lender its obligation to pay such amounts pursuant to this Agreement and (ii) the Borrower shall reimburse such Lender for its reasonable attorneys' and accountants' fees and disbursements incurred in so cooperating with the Borrower in contesting the imposition of such Non-Excluded Tax. (b) If a Lender changes its applicable lending office (other than pursuant to paragraph (c) below) and the effect of the change, as of the date of the change, would be to cause the Borrower to become obligated to pay any additional amount under subsection 4.11 or 4.12, the Borrower shall not be obligated to pay such additional amount. (c) If a condition or an event occurs which would, or would upon the passage of time or giving of notice, result in the payment of any additional amount to any Lender by the Borrower pursuant to subsection 4.11 or 4.12, such Lender shall as soon as reasonably practicable thereafter notify the Borrower and the Administrative Agent and shall take such steps as may reasonably be available to it and acceptable to the Borrower to mitigate the effects of such condition or event (which shall include efforts to rebook the Loans held by such Lender at another lending office, or through another branch or an affiliate, of such Lender); provided that such Lender shall not be required to take any step -------- that, in its reasonable judgment, would be materially disadvantageous to its business or operations or would require it to incur additional costs (unless the Borrower agrees to reimburse such Lender for all such reasonable and actual additional costs). (d) If (and for so long as) the Borrower shall become obligated to pay additional amounts pursuant to subsection 4.11 or 4.12 and any affected Lender shall not 109

have promptly taken the steps necessary to avoid the need for payments under subsection 4.11 or 4.12, the Borrower shall have the right, upon payment in full of all amounts then due from it under subsections 4.11 and 4.12, (i) with the assistance of the Administrative Agent, to seek one or more substitute Lenders reasonably satisfactory to the Administrative Agent and the Borrower to purchase in accordance with the provisions of subsection 11.6(c) the affected Loan, in whole or in part, at an aggregate price no less than the principal amount of such Loan or part thereof being purchased plus accrued and unpaid interest thereon to the date of purchase and all fees and other amounts owing to the affected Lender hereunder (or under the other Loan Documents) and accrued to the date of the purchase (but without payment to the affected Lender of any premium or penalty) and to assume the obligations of the affected Lender under this Agreement and the other Loan Documents, or (ii) after the Borrower has made a good faith effort to seek a substitute Lender in accordance with clause (i) above and provided that no Default or Event of Default has occurred and is continuing, upon at least three Business Days' irrevocable notice to the Administrative Agent and the affected Lender, to terminate the entire Commitment of the affected Lender and to repay the affected Loan, together with accrued and unpaid interest thereon to date of repayment, any amounts payable under subsection 4.13 in connection with such repayment and all fees and other amounts accrued to the date of repayment and owing to the affected Lender hereunder (or under the other Loan Documents) (but without payment to the affected Lender of any premium or penalty). In the case of the substitution of a Lender, the Borrower, the Administrative Agent, the affected Lender, and any substitute Lender shall execute and deliver an appropriately completed Assignment and Acceptance pursuant to subsection 11.6(c) to effect the assignment of rights to, and the assumption of obligations by, the substitute Lender. (e) Notwithstanding any other provision of this Agreement, no Lender shall be entitled to receive any 110

additional amounts pursuant to subsection 4.11 or 4.12 unless such Lender represents to the Borrower that, at the time of any request by such Lender that such amounts be paid, it is the policy or general practice of such Lender to demand such compensation for comparable costs or deductions, if any, in similar circumstances, if any, under comparable provisions of other credit agreements for comparable customers. (f) The obligations of the Borrower and a Lender or Participant under this subsection 4.14 shall survive the termination of this Agreement and the payment of the Notes and all amounts payable.

The Borrower hereby grants to the Administrative Agent, for the benefit of the Issuing Lender and the L/C Participants, a security interest in such cash collateral to secure all obligations of the Borrower in respect of such Letters of Credit under this Agreement and the other Loan Documents. The Borrower shall execute and deliver to the Administrative Agent, for the account of the Issuing Lender and the L/C Participants, such further documents and instruments as the Administrative Agent may request to evidence the creation and perfection of such security interest in such cash collateral account. Amounts held in such cash collateral account shall be applied by the Administrative Agent to the payment of drafts drawn under such Letters of Credit, and the unused portion thereof after all such Letters of Credit shall have expired or been fully drawn upon, if any, shall be applied to repay other obligations of the Borrower hereunder and under the Notes. After all such Letters of Credit shall have expired or been fully drawn upon, all Reimbursement Obligations shall have been satisfied and all other obligations of the 175

Borrower hereunder and under the Notes shall have been paid in full, the balance, if any, in such cash collateral account shall be returned to the Borrower. Except as expressly provided above in this Section, presentment, demand, protest and all other notices of any kind are hereby expressly waived. SECTION 10. THE AGENT 10.1 Appointment. Each Lender hereby irrevocably designates and appoints ----------- (i) Barclays as the Administrative Agent and (ii) Barclays as the Collateral Agent of such Lender under this Agreement and the other Loan Documents. The term "Agent", when used in this Section 10, shall refer to each of (i) Barclays in its capacity as Administrative Agent and (ii) Barclays in its capacity as Collateral Agent. Each such Lender irrevocably authorizes Barclays to act as Administrative Agent and Barclays to act as Collateral Agent of such Lender, to take such action on its behalf under the provisions of this Agreement and the other Loan Documents and to exercise such powers and perform such duties as are expressly delegated to it as Agent by the terms of this Agreement and the other Loan Documents, together with such other powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary elsewhere in this Agreement, neither Agent shall have any duties or responsibilities, except those expressly set forth herein, or any fiduciary relationship with any Lender, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against either Agent. Each Lender acknowledges and consents that (i) the Collateral Agent is also acting in such capacity as agent for the Canadian Administrative Agent and the other Canadian Secured Parties, (ii) the Canadian Administrative Agent is an affiliate of the Administrative Agent and (iii) the Collateral Agent is also acting as Canadian Collateral Agent. 176

10.2 Delegation of Duties. Each Agent may execute any of its duties -------------------- under this Agreement and the other Loan Documents by or through agents (which may include affiliates of such Agent) or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. Neither Agent shall be responsible for the negligence or misconduct of any agents or attorneys-in-fact selected by it with reasonable care. 10.3 Exculpatory Provisions. Neither Agent nor any officer, director, ---------------------- employee, agent, attorney-in-fact or affiliate of any Agent shall be (i) liable for any action lawfully taken or omitted to be taken by it or such Person under or in connection with this Agreement or any other Loan Document (except for its or such Person's gross negligence or willful misconduct) or (ii) responsible in any manner to any of the Lenders or the other Agent for any recitals, statements, representations or warranties made by any Loan Party or any officer thereof contained in this Agreement or any other Loan Document or in any certificate, report, statement or other document referred to or provided for in, or received by such Agent under or in connection with, this Agreement or any other Loan Document or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or the Notes or any other Loan Document or for any failure of the Borrower or the other Agent to perform its obligations hereunder or thereunder. Neither Agent shall be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of the Borrower or any other Loan Party. 10.4 Reliance by Agent. Each Agent shall be entitled to rely, and shall ----------------- be fully protected in relying, upon any Note, writing, resolution, notice, consent, certificate, affidavit, letter, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been 177

signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including, without limitation, counsel to the Borrower), independent accountants and other experts selected by such Agent. Each Agent may deem and treat the payee of any Note as the owner thereof for all purposes unless a written notice of assignment or transfer thereof shall have been filed with the Administrative Agent. Each Agent shall be fully justified as between itself and the Lenders in failing or refusing to take any action under this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the requisite Lending Parties as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. Each Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the Notes and the other Loan Documents in accordance with a request of the requisite Lending Parties, and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and all future holders of the Notes. 10.5 Notice of Default. Neither Agent shall be deemed to have knowledge ----------------- or notice of the occurrence of any Default or Event of Default hereunder unless such Agent has received notice from a Lender or the Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a "notice of default". In the event that an Agent receives such a notice, such Agent shall give notice thereof to the Lenders. Each Agent shall take such action reasonably promptly with respect to such Default or Event of Default as shall be reasonably directed by the Majority Lenders or the Aggregate Majority Lenders; provided that unless and until such Agent shall have received -------- such directions, such Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Lenders. 178

10.6 Non-Reliance on Agent and Other Lenders. Each Lender expressly --------------------------------------- acknowledges that neither Agent nor any of its respective officers, directors, employees, agents, attorneys-in-fact or affiliates has made any representations or warranties to it and that no act by either Agent hereinafter taken, including any review of the affairs of the Borrower or any other Loan Party, shall be deemed to constitute any representation or warranty by such Agent to any Lender. Each Lender represents to each Agent that it has, independently and without reliance upon either Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other condition and creditworthiness of the Borrower and the other Loan Parties and made its own decision to make its Loans hereunder and enter into this Agreement. Each Lender also represents that it will, independently and without reliance upon either Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, financial and other condition and creditworthiness of the Borrower and the other Loan Parties. Except for notices, reports and other documents expressly required to be furnished to the Lenders by an Agent hereunder, such Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, condition (financial or otherwise), prospects or creditworthiness of the Borrower or any other Loan Party which may come into the possession of such Agent or any of its respective officers, directors, employees, agents, attorneys-in-fact or Affiliates. 10.7 Indemnification. Each Lender agrees to indemnify each Agent in its --------------- respective capacities as such (to the extent not reimbursed by the Borrower or any other 179

Loan Party and without limiting the obligation of the Borrower or any other Loan Party to do so), ratably according to its Commitment Percentage in effect on the date on which indemnification is sought under this subsection 10.7, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever which may at any time (including, without limitation, at any time following the payment of the Loans) be imposed on, incurred by or asserted against such Agent in any way relating to or arising out of this Agreement, any of the other Loan Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by such Agent under or in connection with any of the foregoing; provided that no Lender shall be liable for the payment of any -------- portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting solely from the gross negligence or willful misconduct of such Agent. The agreements in this subsection shall survive the payment of the Loans and all other amounts payable hereunder. 10.8 Agent in Its Individual Capacity. Each Agent and its affiliates -------------------------------- may make loans to, accept deposits from and generally engage in any kind of business with the Borrower and/or the other Credit Parties as though such Agent was not the Administrative Agent or the Collateral Agent (as applicable) hereunder and under the other Loan Documents. With respect to the Loans made or renewed by an Agent and any Note issued to it and with respect to any Letter of Credit issued or participated in by it, such Agent shall have the same rights and powers under this Agreement and the other Loan Documents as any Lender and may exercise the same as though it were not the Administrative Agent or the Collateral Agent (as applicable), and the terms "Lender" and "Lenders" shall include the Agent in its individual capacity. 180

10.9 Successor Agent. Each of Administrative Agent and Collateral Agent --------------- may resign its role as such hereunder and under the other Loan Documents upon 30 days' notice to the Lenders. If an Agent shall resign as Administrative Agent or Collateral Agent (as applicable) under this Agreement and the other Loan Documents, then the Aggregate Majority Lenders shall appoint from among the Lenders a successor agent for the Lenders, which successor agent shall be approved by the Borrower, whereupon such successor agent shall succeed to the rights, powers and duties of the resigning Administrative Agent or Collateral Agent (as applicable), and the terms "Administrative Agent" or "Collateral Agent" (as applicable) shall mean such successor agent effective upon such appointment and approval, and the former Agent's rights, powers and duties as Administrative Agent or Collateral Agent (as applicable) shall be terminated, without any other or further act or deed on the part of such former Agent or any of the parties to this Agreement or any holders of the Notes; provided that the -------- resigning Agent shall execute all documents which the replacement Agent deems necessary or desirable to effect such substitution. After any resigning Agent's resignation as Administrative Agent or Collateral Agent (as applicable), the provisions of this subsection shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent or Collateral Agent (as applicable) under this Agreement and the other Loan Documents. 10.9 Swing Line Lender. The provisions of this Section 10 shall apply ----------------- to the Swing Line Lender in its capacity as such to the same extent that such provisions apply to the Agents. 10.11 Co-Agents. Each party hereto agrees that the Co-Agents have no --------- rights or obligations hereunder or under the other Credit Documents in their respective capacities as such. 181

(b) Any Lender may, in the ordinary course of its commercial banking business and in accordance with applicable law, at any time sell to one or more banks or other entities ("Participants") participating interests in any Loan ------------ owing to such Lender, any Note held by such Lender, any Commitment of such Lender or any other interest of such Lender hereunder and under the other Loan Documents. In the event of any such sale by a Lender of a participating interest to a Participant, such Lender's obligations under this Agreement to the other parties to this Agreement shall remain unchanged, such Lender shall remain solely responsible for the performance thereof, such Lender shall remain the holder of any such Note for all purposes under this Agreement and the other Loan Documents, and the Borrower, the Administrative Agent and the Collateral Agent shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement and the other Loan Documents. Any agreement pursuant to which any Lender shall sell any such participating interest shall provide that such Lender shall retain the sole right and responsibility to exercise such Lender's rights and enforce the Borrower's obligations hereunder, including the right to consent to any amendment, supplement, modification or waiver of any provision of this Agreement or any of the other Loan Documents, provided that such participation agreement -------- may provide that such Lender will not agree to any amendment, supplement, modification or waiver described in clause (i) or (ii) of the proviso to the second sentence of subsection 11.1 without the consent of the Participant. The Borrower agrees that if amounts outstanding under this Agreement and the Notes are due or unpaid, or shall have been declared or shall have become due and payable upon the occurrence of an Event of Default, each Participant shall be deemed to have the right of setoff in respect of its participating interest in amounts owing under this Agreement and any Note to the same extent as if the amount of its participating interest were owing directly to it as a Lender under this Agreement or any Note, provided that, in purchasing such participating -------- interest, such Participant shall be deemed to have agreed to share with the 189

Lenders the proceeds thereof as provided in subsection 11.7(a) as fully as if it were a Lender hereunder. The Borrower agrees that each Lender shall be entitled to the benefits of subsections 4.10, 4.11, 4.12, 4.13 and 11.1 without regard to whether it has granted any participating interests, and that all amounts payable to a Lender under subsections 4.10, 4.11, 4.12 and 4.13 shall be determined as if such Lender had not granted any such participating interests. (c) Any Lender may, in the ordinary course of its commercial banking business and in accordance with applicable law, at any time and from time to time assign to any Lender or any Affiliate thereof or, with the prior written consent of the Borrower and the Administrative Agent, to an additional bank or financial institution (an "Assignee") all or any part of its rights and -------- obligations under this Agreement and the Notes, including, without limitation, its Commitments, L/C Obligations and Loans, pursuant to an Assignment and Acceptance, substantially in the form of Exhibit G, executed by such Assignee, such assigning Lender (and, in the case of an Assignee that is not then a Lender or an Affiliate thereof, by the Borrower and the Administrative Agent) and delivered to the Administrative Agent for its acceptance and recording in the Register; provided that (i) in the case of any -------- such transfer of the full amount of such assigning Lender's Commitment to an additional bank or financial institution, the consent of the Administrative Agent and the Borrower shall not be unreasonably withheld, (ii) if any Lender assigns all or any part of its rights and obligations under this Agreement to one of its Affiliates in connection with or in contemplation of the sale of its interest in such Affiliate, the Borrower's prior written consent (not to be unreasonably withheld) shall be required for such assignment and (iii) if any Lender assigns a part of its rights and obligations under this Agreement to an Assignee, such Lender shall assign proportionate interests in its Commitment, Revolving Credit Loans, L/C Obligations, participations in Swing Line Loans and Letters of Credit and other rights and obligations 190

hereunder to such Assignee; and provided, further, that no Common Lender shall -------- be permitted to make an assignment of its rights and obligations hereunder to an Assignee unless the parent, subsidiary or affiliate of such Common Lender which is party to the Canadian Credit Agreement makes a concurrent and proportionate assignment of its rights and obligations thereunder to a parent, subsidiary or affiliate of the proposed Assignee, such assignment to be effected in accordance with subsection 12.6(c) of the Canadian Credit Agreement. Upon such execution, delivery, acceptance and recording, from and after the effective date determined pursuant to such Assignment and Acceptance, (x) the Assignee thereunder shall be a party hereto and, to the extent provided in such Assignment and Acceptance, have the rights and obligations of a Lender hereunder with a Commitment as set forth therein, and (y) the assigning Lender thereunder shall be released from its obligations under this Agreement to the extent that such obligations shall have been expressly assumed by the Assignee pursuant to such Assignment and Acceptance (and, in the case of an Assignment and Acceptance covering all or the remaining portion of an assigning Lender's rights and obligations under this Agreement, such assigning Lender shall cease to be a party hereto). Notwithstanding the foregoing, no Assignee, which as of the date of any assignment to it pursuant to this subsection 11.6(c) would be entitled to receive any greater payment under subsection 4.11 or 4.12 than the assigning Lender would have been entitled to receive as of such date under such subsections with respect to the rights assigned, shall be entitled to receive such payments unless the Borrower has consented in writing to the assignment. (d) The Administrative Agent shall maintain at its address referred to in subsection 11.2 a copy of each Assignment and Acceptance delivered to it and a register (the "Register") for the recordation of the names and addresses of -------- the Lenders and the Commitment of, and principal amount of the Loans owing to, each Lender from time to time. The entries in the Register shall be conclusive, in the absence of manifest error, and the 191

Borrower, the Administrative Agent, the Collateral Agent and the Lenders may treat each Person whose name is recorded in the Register as the owner of the Loan recorded therein for all purposes of this Agreement. The Register shall be available for inspection by the Borrower, the Collateral Agent or any Lender at any reasonable time and from time to time upon reasonable prior notice. (e) Upon its receipt of an Assignment and Acceptance executed by an assigning Lender and an Assignee (and, in the case of an Assignee that is not then a Lender or an Affiliate thereof, executed by the Borrower and the Administrative Agent), together with payment to the Administrative Agent of a registration and processing fee of $1,500 (in the case of any assignment to a Lender or an Affiliate thereof) and $3,500 (in the case of any other assignment), the Administrative Agent shall (i) promptly accept such Assignment and Acceptance and (ii) on the effective date determined pursuant thereto record the information contained therein in the Register and give prompt notice of such acceptance and recordation to the Lenders and the Borrower. On or prior to such effective date, the assigning Lender shall surrender the outstanding Notes held by it all or a portion of which are being assigned, and the Borrower, at its own expense, shall execute and deliver to the Administrative Agent (in exchange for the outstanding Notes of the assigning Lender) a new Revolving Credit Note and/or Swing Line Note, as the case may be, to the order of such Assignee and representing the obligation of the Borrower to pay an amount equal to (i) in the case of a Revolving Credit Note, the lesser of (A) the amount of such Assignee's Commitment and (B) the aggregate principal amount of all Revolving Credit Loans made by such Assignee, and (ii) in the case of a Swing Line Note, the lesser of (A) the Swing Line Commitment and (B) the aggregate principal amount of all Swing Line Loans made by such Assignee, in each case with respect to the relevant Commitment after giving effect to such Assignment and Acceptance and, if the assigning Lender has retained a Commitment hereunder, a new Revolving Credit Note and Swing 192

Line Note, as the case may be, to the order of the assigning Lender and representing the obligation of the Borrower to pay an amount equal to (i) in the case of a Revolving Credit Note, the lesser of (A) the amount of such Lender's Commitment and (B) the aggregate principal amount of all Revolving Credit Loans made by such Lender, and (ii) in the case of a Swing Line Note, the lesser of (A) the Swing Line Commitment and (B) the aggregate principal amount of all Swing Line Loans made by such Lender, in each case with respect to the relevant Commitment after giving effect to such Assignment and Acceptance. Such new Notes shall be dated the Closing Date and shall otherwise be in the form of the Note replaced thereby. The Notes surrendered by the assigning Lender shall be returned by the Administrative Agent to the Borrower marked "cancelled". (f) The Borrower authorizes each Lender to disclose to any Participant or Assignee (each, a "Transferee") and any prospective Transferee, subject to ---------- the provisions of subsection 11.15, any and all financial information in such Lender's possession concerning the Borrower and its Affiliates which has been delivered to such Lender by or on behalf of the Borrower pursuant to this Agreement or which has been delivered to such Lender by or on behalf of the Borrower in connection with such Lender's credit evaluation of the Borrower and its Affiliates prior to becoming a party to this Agreement. No assignment or participation made or purported to be made to any Transferee shall be effective without the prior written consent of the Borrower if it would require the Borrower to make any filing with any Governmental Authority or qualify any Loan or Note under the laws of any jurisdiction.

After giving effect to the Succession and assuming the filing of the Financing Statements in the Filing Offices, the Collateral Agent has a perfected security interest in such Collateral of the Borrower (excluding fixtures, as defined in the UCC), to the extent perfection may be accomplished by the filing of financing statements under the UCC, and no further filings are required pursuant to the UCC in the State of New York as a result of the execution and delivery of the Amended and

Investment Company Act. Neither the Borrower nor Holdings is an ---------------------- "investment company," or a company "controlled" by an "investment company," within the meaning of the Investment Company Act of 1940, as amended. Our opinion set forth in paragraph 4 above is subject to the effects of (a) bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium - and other similar laws relating to or affecting creditors' rights or remedies generally; (b) general equitable principles (whether considered in a proceeding - in equity or at law); (c) an implied covenant of good faith and fair dealing; - (d) applicable state laws and interpretations which may affect the validity or - enforceability of certain remedies provided for in the Transaction Documents, which limitations, however, do not, in our opinion, make the remedies provided for therein inadequate for the practical realization of the rights and benefits intended to be provided thereby (subject to the other qualifications expressed herein); and (e) limitations on enforceability of rights to indemnification - under Federal or state securities laws or regulations or to the extent such indemnification would violate public policy. We express no opinion as to (1) the - enforceability of any waiver of any statutory right, (2) the security interest - referred to in the second paragraph of Section 9 of the Amended and Restated Credit Agreement, (3) the enforceability of the penultimate sentence of - subsection 11.6(b), (4) subsection 11.12(a) of the Amended and Restated Credit - Agreement, paragraph 21(a) of the Holdings Guarantee, and any similar provision in any other Transaction Document, insofar as such provisions relate to the subject matter jurisdiction of the United States District Court for the

Barclays Bank PLC, as Administrative Agent, et al. 10 March 14, 1997 Southern District of New York to adjudicate any controversy, (5) the waiver of - inconvenient forum set forth in subsection 11.12(b) of the Amended and Restated Credit Agreement, paragraph 21(b) of the Holdings Guarantee and any similar provision in any other Transaction Document and (6) the enforceability of - paragraph 19 of the Holdings Guarantee. We express no opinion as to the validity or perfection of any security interest, or the validity, binding effect or enforceability of any Transaction Document to the extent that such Transaction Document grants or purports to grant a security interest, (i) that is not governed by the UCC - (including but not limited to any such security interest with respect to Copyrights, Copyright Licenses, Patents, Patent Licenses, Trademarks and Trademark Licenses (as such terms are defined in the Borrower Security Agreement), deposit accounts and insurance policies), (ii) in any collateral of -- a type described in Section 9-401(1)(a) or (b) of the UCC, (iii) in any --- collateral that is an "uncertificated security" (as defined in Section 8- 102(1)(b) of the UCC), or (iv) collateral that contains or is governed by -- provisions that purport to void or prohibit the assignment thereof, or that are otherwise violated, if it is assigned pursuant to a document such as the Borrower Security Agreement, including, without limitation, any Accounts the obligor for which is the United States of America or any department, agency or instrumentality thereof. No security interest will exist with respect to after- acquired property of the Borrower or Holdings until such party has rights therein within the meaning of Section 9-203 of the UCC. We express no opinion herein as to the title or any other interest of the Borrower or Holdings in or to any of the collateral described in the Transaction Documents.

Barclays Bank PLC, as Administrative Agent, et al. 12 March 14, 1997 requires periodic filing of continuation statements in order to maintain the effectiveness of financing statements filed pursuant thereto and (iii) Sections --- 8-304 and 8-311 of the UCC may in certain circumstances limit the rights of a secured party in respect of any unauthorized endorsement with respect to certificated securities constituting collateral under the Transaction Documents not registered in the name of or issued to the Collateral Agent and not originally issued in bearer form.

We express no opinion as to the validity, binding effect or enforceability of any provision of any Transaction Document that purports (i) to - waive, release or vary any right of, or any duties owing to, the Borrower or Holdings, to the extent limited by Section 1-102(3) or 9-501(3) of the UCC or other provisions of applicable law, (ii) to prohibit the Borrower or Holdings -- from transferring its respective rights in the collateral described in the Transaction Documents or any proceeds thereof, as a result of the operation of Section 9-311 of the UCC, or (iii) to permit the Collateral Agent or the --- Administrative Agent to vote or otherwise exercise any rights with respect to any of the collateral under the Transaction Documents absent compliance with the requirements of applicable laws and regulations as to the voting of or other exercise of rights with respect to such collateral. We express no opinion as to the effect of, or compliance with, any Federal or state laws regarding fraudu-

We express no opinion as to the laws of any jurisdiction other than the laws of the State of New York, the DGCL and the Federal laws of the United States of America. In particular (and without limiting the generality of the foregoing), we express no opinion as to the law of Canada or any province thereof or as to the effect of such law (whether limiting, prohibitive or otherwise) on any of the rights or obligations of any Loan Party or of any other party to or beneficiary of any of the Transaction Documents.

Neither the Collateral Agent nor any other Secured Party shall have any obligation to protect, secure, perfect or insure any Lien at any time held by it as security for the Obligations or for this Guarantee or any property subject thereto. When making any demand hereunder against any of the Guarantors, the Collateral Agent or any other Secured Party may, but 10

shall be under no obligation to, make a similar demand on the Borrower or any other Guarantor or guarantor, and any failure by the Collateral Agent or any other Secured Party to make any such demand or to collect any payments from the Borrower or any such other Guarantor or guarantor, or any release of the Borrower or such other Guarantor or guarantor, shall not relieve any of the Guarantors in respect of which a demand or collection is not made or any of the Guarantors not so released of their several obligations or liabilities hereunder, and shall not impair or affect the rights and remedies, express or implied, or as a matter of law, of the Collateral Agent or any other Secured Party against any of the Guarantors. For the purposes hereof "demand" shall include the commencement and continuance of any legal proceedings. 7. Guarantee Absolute and Unconditional. Each Guarantor waives any ------------------------------------ and all notice of the creation, renewal, extension or accrual of any of the Obligations and notice of or proof of reliance by the Collateral Agent or any other Secured Party upon this Guarantee or acceptance of this Guarantee; the Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred, or renewed, extended, amended or waived, in reliance upon this Guarantee; and all dealings between the Borrower, the Canadian Borrower, any other Credit Party and any of the Guarantors, on the one hand, and the Collateral Agent and the other Secured Parties, on the other, shall likewise be conclusively presumed to have been had or consummated in reliance upon this Guarantee.

(a) The Borrower may request the ----------------------- creation of Acceptances hereunder by submitting to the Administrative Agent at its office specified in subsection 12.2 prior to 2:00 P.M., Toronto time, one Business Day prior to the requested Borrowing Date, (i) a request for acceptances ("Request for Acceptances") completed in a manner in form and ----------------------- substance reasonably satisfactory to the Administrative Agent and specifying, among other things, the Borrowing Date, maturity and amount of the Drafts to be accepted and discounted, (ii) to the extent not theretofore supplied to each Lender, a sufficient number of Drafts to be drawn on the Lenders, to be appropriately completed in accordance with subsection 3.2(d) and (iii) such other certificates, documents and other papers and information as the Administrative Agent may reasonably request. (b) In connection with each utilization by it of the Commitments by way of Acceptances, the Borrower hereby agrees that it shall deliver to the Administrative Agent on the Closing Date Powers of Attorney substantially in the form annexed hereto as Exhibit C (each, a "Power of Attorney") authorizing each ----------------- Lender to draw Drafts on such Lender on behalf of the Borrower and to complete such Drafts in accordance with the Requests for Acceptances submitted from time to time pursuant to Section 3.2(a) hereof. (c) Each Draft requested by or on behalf of the Borrower for acceptance hereunder shall be denominated in Canadian Dollars, shall have an undiscounted face amount equal to C$500,000 or whole multiple of C$100,000 in excess thereof, shall be dated the Borrowing Date specified in the Request for Acceptances with respect thereto and shall be stated to mature on a Business Day which is 30, 60, 90 or 180 days after the date thereof (and, in any event, prior to the Termination Date). (d) Not later than 12:00 P.M., Toronto time, on the Borrowing Date specified in the relevant Request for Acceptances, and upon fulfillment of the applicable 60

conditions set forth in Section 7, each Lender will, in accordance with such Request for Acceptances, (i) sign each Draft on behalf of the Borrower pursuant to the Power of Attorney, (ii) complete the date, amount and maturity of each Draft to be accepted, (iii) accept such Drafts and give notice to the Administrative Agent of such acceptance and (iv) upon such acceptance, discount such Acceptances to the extent contemplated by subsection 3.3. 3.3 Discount of Acceptances. (a) Each Lender hereby agrees, on the ----------------------- terms and subject to the conditions set forth in this Agreement, to discount Acceptances created by it on the Borrowing Date with respect thereto at the applicable Reference Discount Rate by making available to the Borrower an amount in immediately available funds equal to the Acceptance Purchase Price in respect thereof, and to notify the Administrative Agent that such Draft has been accepted and discounted by the accepting Lender. (b) In the event that the Borrower has made a Request for Acceptances, then (i) prior to 11:00 A.M., Toronto time, on the Borrowing Date with respect thereto, Bank of Nova Scotia will notify the Borrower and the Lenders of the Reference Discount Rate applicable to such Acceptance and (ii) if such Reference Discount Rate is acceptable to the Borrower, the Lenders shall make the Acceptance Purchase Price for the Acceptance discounted by it available to the Administrative Agent, for the account of the Borrower, at the office of the Administrative Agent specified in subsection 12.2 prior to 12:00 P.M., Toronto time, on the Borrowing Date, in funds immediately available to the Administrative Agent. Such borrowing will then be made available to the Borrower by the Administrative Agent crediting the account of the Borrower on the books of such office with the aggregate of the amounts made available to the Administrative Agent by the Lenders and in like funds as received by the Administrative Agent. (c) Acceptances discounted by any Lender may be held by it for its own account until maturity or sold by it 61

at any time prior thereto in the relevant market therefor in Canada in such Lender's sole discretion. 3.4 Stamping Fees. On the Borrowing Date with respect to each ------------- Acceptance, the Borrower shall pay to the Administrative Agent, for the account of the Lenders, a stamping fee at a rate per annum equal to 1.50% minus the ----- Margin Reduction Percentage, computed for the period from and including the Borrowing Date with respect to such Acceptance to the maturity of such Acceptance, calculated on the basis of a 365-day year of the undiscounted face amount of such Acceptance. 3.5 Acceptance Reimbursement Obligations. (a) The Borrower hereby ------------------------------------ unconditionally agrees to pay to each Lender, on the maturity date (whether at stated maturity, by acceleration or otherwise) for each Acceptance created by such Lender for the account of the Borrower, the aggregate undiscounted face amount of each such then-maturing Acceptance. (b) The obligation of the Borrower to reimburse the Lenders for then-maturing Acceptances may be satisfied by the Borrower by: (i) paying to the Administrative Agent, for the account of the Lenders, the aggregate undiscounted face amount of all Acceptances created for the account of the Borrower hereunder which are then maturing by 12:00 P.M., Toronto time, on such maturity date; provided that the Borrower -------- shall have given one Business Day's prior notice to the Administrative Agent (which shall promptly notify each Lender thereof) of its intent to reimburse the Lenders in the manner contemplated by this clause (i); (ii) having new Drafts accepted and discounted by the Lenders in the manner contemplated by subsections 3.2 and 3.3 in substitution for the then-maturing Acceptances; provided that (A) the Borrower shall have -------- 62

delivered to the Administrative Agent (which shall promptly provide a copy thereof to each Lender) a duly completed Request for Acceptances not later than 2:00 P.M., Toronto time, one Business Day prior to such maturity date, together with the documents, instruments, certificates and other papers and information contemplated by subsections 3.2(a)(ii) and 3.2(a)(iii), (B) if any Default or Event of Default (other than a Default or an Event of Default under Section 10(j) which occurs solely as result of the occurrence of a U.S. Borrowing Base Default) has occurred and is then continuing and the Administrative Agent or the Majority Lenders shall have given notice to the Borrower that creation of Acceptances is not appropriate, the Request for Acceptances shall be deemed to be a request for a Prime Rate Loan, (D) each Lender shall retain the Acceptance Purchase Price for the Acceptance created by it and apply such Acceptance Purchase Price to the Acceptance Reimbursement Obligations of the Borrower in respect of the maturing Acceptance and (E) if the Acceptance Purchase Price so retained by such Lender is less than the undiscounted face amount of the then-maturing Acceptance, the Borrower shall have made arrangements reasonably satisfactory to such Lender for payment of such deficiency; or (iii) to the extent that the Borrower has not given to the Administrative Agent a notice contemplated by clause (i) or (ii) above, then the Borrower shall be deemed to have requested a borrowing pursuant to subsection 2.3 of Prime Rate Loans in the undiscounted face amount of such Acceptance. The Borrowing Date with respect to such borrowing shall be the maturity date (or such earlier date as the Commitment shall be terminated) for such Acceptance. Except to the extent that any of the events contemplated by Section 10(f)(i) or (ii) with respect to the Borrower has occurred and is then continuing (in which case the Borrower shall be obligated to pay to each Lender the undiscounted face 63

amount of the Acceptances created by such Lender which are then maturing), each Lender shall be obligated to make the Prime Rate Loan contemplated by this subsection 3.5(b)(iii) regardless of whether the conditions precedent to borrowing set forth in this Agreement are then satisfied. The proceeds of any Prime Rate Loans made pursuant to this subsection 3.5(b)(iii) shall be retained by the Lenders and applied by them to the Acceptance Reimbursement Obligations of the Borrower in respect of the then-maturing Acceptance. (c) The unpaid amount of any such Acceptance Reimbursement Obligations shall be treated as a Prime Rate Loan for the purposes hereof and interest shall accrue on the amount of any such unpaid Acceptance Reimbursement Obligation from the date such amount becomes due until paid in full at a fluctuating rate per annum equal to the rate which would then be payable on Prime Rate Loans. Such interest shall be payable by the Borrower on demand by the Administrative Agent. (d) In no event shall the Borrower claim from any Lender any grace period with respect to the payment at maturity of any Acceptances created by such Lender pursuant to this Agreement. 3.6 Converting Loans to Acceptances and Acceptances to Loans. (a) -------------------------------------------------------- Subject to subsection 3.6(b), the Borrower may at any time and from time to time request that any then outstanding Revolving Credit Loan owing by it be converted into an Acceptance by delivering to the Administrative Agent (which shall promptly provide a copy thereof to each Lender) a Request for Acceptances, together with a statement that the Acceptances so requested are to be created pursuant to this subsection 3.6(a), such notice to be given not later than three Business Days prior to the requested conversion date. 64

(b) In the event that the Administrative Agent receives such a Request for Acceptances and the accompanying statement described in subsection 3.6(a), then the Borrower shall pay on the requested Borrowing Date to the Administrative Agent, for the account of the Lenders, the principal amount of the then outstanding Revolving Credit Loans being so converted, and each Lender shall accept and discount the Borrower's Drafts having an aggregate face amount at least equal to the principal amount of the Revolving Credit Loans of such Lender which are then being repaid; provided that, following the occurrence and -------- during the continuance of a Default or an Event of Default (other than a Default or an Event of Default arising under Section 10(j) which occurs solely as a result of the occurrence of a U.S. Borrowing Base Default), (i) no Acceptance may be created when the Administrative Agent has or the Majority Lenders have given notice to the Borrower that creation of Acceptances is not appropriate and (iii) no Acceptance which is permitted to be created hereunder shall have a maturity that extends beyond the Termination Date. (c) The creation of Acceptances pursuant to this subsection 36 shall not be subject to the satisfaction of the conditions precedent to borrowing set forth in this Agreement. (d) The Borrower may elect from time to time to convert outstanding Acceptances to Revolving Credit Loans by giving the Administrative Agent at least one Business Day's irrevocable notice of such election prior to the maturity of such Acceptances, provided that any such conversion of Acceptances -------- may only be made on the maturity thereof. 3.7 Acceptances to be Supplemented by Prime Rate Loans in order to be ----------------------------------------------------------------- Created Ratably. The Borrower hereby agrees that each Request for Acceptances, - --------------- reimbursement of Acceptances and conversion of Revolving Credit Loans to Acceptances shall be made in a manner so that any such Request for Acceptances, reimbursement or conversion shall apply ratably to all Lenders and so that, after giving 65

effect to such Request for Acceptances, reimbursement or conversion, as the case may be, each Lender shall hold its ratable share of the aggregate amount of Acceptances which mature on the same day. In the event that the aggregate amount of Acceptances requested by the Borrower to be created by all Lenders hereunder pursuant to any Request for Acceptances is an amount which, if divided ratably among the Lenders, would not result in each Lender accepting a Draft which has an undiscounted face amount equal to C$500,000 or a whole multiple of C$100,000 in excess thereof, then each Lender's ratable share of such Acceptance shall be rounded downward to an amount which is equal to C$500,000 or a whole multiple of C$100,000 in excess thereof, and the Borrower shall be deemed to have requested that such Lender make a Prime Rate Loan to the Borrower (which Loan need not satisfy the minimum borrowing requirements of subsection 2.3) on the date upon which such Draft is to be accepted in the amount by which such Lender's ratable share of the Acceptance requested in such Request for Acceptances was rounded downward. 3.8 Special Provisions Relating to Non-Chartered Banks. (a) The -------------------------------------------------- Borrower and each Lender hereby acknowledge and agree that from time to time certain Lenders which are not Canadian chartered banks or which are Canadian "Schedule II" chartered banks may not be authorized to or may, as a matter of general corporate policy, elect not to accept Drafts, and the Borrower and each Lender agrees that any such Lender may purchase Acceptance Notes of the Borrower in accordance with the provisions of subsection 3.8(b) in lieu of creating Acceptances for its account. (b) In the event that any Lender described in subsection 3.8(a) above is unable to, or elects as a matter of general corporate policy not to, create Acceptances hereunder, such Lender shall not create Acceptances hereunder, but rather the Borrower requesting the creation of such Acceptances shall deliver to such Lender non-interest bearing promissory notes (the "Acceptance Notes") of the Borrower, substantially in the form of Exhibit E to ---------------- 66

the Existing Credit Agreement, having the same maturity as the Acceptances to be created and in an aggregate principal amount equal to the undiscounted face amount thereof. Each such Lender hereby agrees to purchase its Acceptance Note at a purchase price equal to the Acceptance Purchase Price which would have been applicable if a Draft had been accepted by it (less any stamping fee which would have been paid pursuant to subsection 3.4 if such Lender had created an Acceptance) and such Acceptance Notes shall be governed by the provisions of this Section 3 as if they were Acceptances. SECTION 4. LETTERS OF CREDIT 4.1 L/C Commitment. (a) Subject to the terms and conditions hereof, -------------- the Issuing Lender, in reliance on the agreements of the other Lenders set forth in subsection 4.4(a), agrees to issue letters of credit ("Letters of Credit") ----------------- for the account of the Borrower on any Business Day during the Commitment Period in such form as may be approved from time to time by the Issuing Lender; provided that the Issuing Lender shall have no obligation to issue any Letter of - -------- Credit if, after giving effect to such issuance, (i) the L/C Obligations would exceed the L/C Commitment or (ii) the Aggregate Outstandings of all Lenders would exceed the lesser of (x) the aggregate Commitments and (y) the Borrowing Base then in effect. Each Letter of Credit shall (i) be denominated in Canadian Dollars and shall be either (x) a standby letter of credit issued to support obligations of the Borrower or any of its Subsidiaries, contingent or otherwise, which finance the working capital and business needs of the Borrower and its Subsidiaries incurred in the ordinary course of business (a "Standby Letter of ----------------- Credit"), or (y) a commercial letter of credit in respect of the purchase of - ------ goods or services by the Borrower or any of its Subsidiaries in the ordinary course of business (a "Commercial Letter of Credit"), (ii) expire no later than --------------------------- the Termination Date, and (iii) expire no later than 365 days after its date of issuance. 67

(b) Each Letter of Credit shall be subject to the Uniform Customs and, to the extent not inconsistent therewith, the laws of the Province of Ontario and the laws of Canada applicable therein. (c) The Issuing Lender shall not at any time be obligated to issue any Letter of Credit hereunder if such issuance would conflict with, or cause the Issuing Lender or any L/C Participant to exceed any limits imposed by, any applicable Requirement of Law. 4.2 Procedure for Issuance of Letters of Credit. The Borrower may ------------------------------------------- from time to time request that the Issuing Lender issue a Letter of Credit by delivering to the Issuing Lender, at its address for notices specified herein, an Application therefor, completed to the reasonable satisfaction of the Issuing Lender, and such other certificates, documents and other papers and information as the Issuing Lender may reasonably request. Upon receipt of any Application, the Issuing Lender will process such Application and the certificates, documents and other papers and information delivered to it in connection therewith in accordance with its customary procedures and shall promptly issue the Letter of Credit requested thereby (but in no event shall the Issuing Lender be required to issue any Letter of Credit earlier than three Business Days after its receipt of the Application therefor and all such other certificates, documents and other papers and information relating thereto) by issuing the original of such Letter of Credit to the beneficiary thereof or as otherwise may be agreed by the Issuing Lender and the Borrower. The Issuing Lender shall furnish a copy of such Letter of Credit to the Borrower promptly following the issuance thereof. 4.3 Fees, Commissions and Other Charges. (a) The Borrower shall pay ----------------------------------- to the Administrative Agent, for the account of the Issuing Lender and the L/C Participants, a letter of credit commission with respect to each Letter of Credit, for the period from and including the date of issuance of such Letter of Credit to the expiration date of 68

such Letter of Credit, computed at the L/C Commission Rate, calculated on the basis of a 365- (or 366-, as the case may be) day year, on the aggregate amount available to be drawn under such Letter of Credit, payable quarterly in arrears on each L/C Fee Payment Date to occur during such period and on the expiration date of such Letter of Credit. Such commissions shall be payable to the Lenders to be shared ratably among them in accordance with their respective Commitment Percentages. In addition, the Borrower shall pay to the Administrative Agent, for the account of the Issuing Bank, a fronting fee with respect to each Letter of Credit, for the period from and including the date of issuance of such Letter of Credit to the expiration date of such Letter of Credit, computed at a rate of 1/8 of 1% per annum, calculated on the basis of a 365- (or 366-, as the case may be) day year, on the product of (i) the aggregate of the Commitment Percentages of the L/C Participants multiplied by (ii) the aggregate amount available to be drawn under such Letter of Credit, payable quarterly in arrears on each L/C Fee Payment Date to occur during such period and on the expiration date of such Letter of Credit. Such fees and commissions shall be nonrefundable. (b) In addition to the foregoing fees and commissions, the Borrower shall pay or reimburse the Issuing Lender for such normal and customary costs and expenses as are incurred or charged by the Issuing Lender in issuing, effecting payment under, amending or otherwise administering any Letter of Credit. (c) The Administrative Agent shall, promptly following its receipt thereof, distribute to the Issuing Lender and the L/C Participants all fees and commissions received by the Administrative Agent for their respective accounts pursuant to this subsection. 4.4 L/C Participations. (a) The Issuing Lender irrevocably agrees ------------------ to grant and hereby grants to each L/C Participant, and, to induce the Issuing Lender to issue Letters of Credit hereunder, each L/C Participant 69

irrevocably agrees to accept and purchase and hereby accepts and purchases from the Issuing Lender, on the terms and conditions hereinafter stated, for such L/C Participant's own account and risk an undivided interest equal to such L/C Participant's Commitment Percentage (as in effect from time to time) in the Issuing Lender's obligations and rights under each Letter of Credit issued hereunder and the amount of each draft paid by the Issuing Lender thereunder. Each L/C Participant unconditionally and irrevocably agrees with the Issuing Lender that, if a draft is paid under any Letter of Credit for which the Issuing Lender is not reimbursed in full by the Borrower in accordance with subsection 4.5(a), such L/C Participant shall pay to the Issuing Lender at the Issuing Lender's address for notices specified herein an amount equal to such L/C Participant's Commitment Percentage (in effect on the date of such demand) of the amount of such draft, or any part thereof, which is not so reimbursed, such payment to be made by such L/C Participant on the date (which shall be a Business Day) a demand therefor is made by the Issuing Lender (if such demand is made prior to 12:00 P.M. Toronto time on such date) or the next Business Day (if such demand is made after 12:00 P.M. Toronto time on such date). (b) If any amount required to be paid by any L/C Participant to the Issuing Lender pursuant to subsection 4.4(a) in respect of any unreimbursed portion of any payment made by the Issuing Lender under any Letter of Credit is paid to the Issuing Lender within three Business Days after the date such payment is due, such L/C Participant shall pay to the Issuing Lender on demand an amount equal to the product of (i) such amount, times (ii) the weekly average Bank of Canada Rate, during the period from and including the date such payment is required to the date on which such payment is immediately available to the Issuing Lender, times (iii) a fraction the numerator of which is the number of days that elapse during such period and the denominator of which is 365 (or 366, as the case may be). If any such amount required to be paid by any L/C Participant pursuant to subsection 4.4(a) is not in fact made available to the 70

Issuing Lender by such L/C Participant within three Business Days after the date such payment is due, the Issuing Lender shall be entitled to recover from such L/C Participant, on demand, such amount with interest thereon calculated from such due date at the rate per annum applicable to Prime Rate Loans hereunder. A certificate of the Issuing Lender submitted to any L/C Participant with respect to any amounts owing under this subsection shall be conclusive in the absence of manifest error. (c) Whenever, at any time after the Issuing Lender has made payment under any Letter of Credit and has received from any L/C Participant its pro --- rata share of such payment in accordance with subsection 4.4(a), the Issuing - ---- Lender receives any payment related to such Letter of Credit (whether directly from the Borrower or otherwise, including proceeds of Collateral applied thereto by the Issuing Lender), or any payment of interest on account thereof, the Issuing Lender will, if such payment is received prior to 12:00 Noon, Toronto time, on a Business Day, distribute to such L/C Participant its pro rata share --- ---- thereof prior to the end of such Business Day and otherwise the Issuing Lender will distribute such payment on the next succeeding Business Day; provided, -------- however, that in the event that any such payment received by the Issuing Lender - ------- shall be required to be returned by the Issuing Lender, such L/C Participant shall return to the Issuing Lender the portion thereof previously distributed by the Issuing Lender to it. 4.5 Reimbursement Obligation of the Borrower. (a) The Borrower ---------------------------------------- agrees to reimburse the Issuing Lender, upon receipt of notice from the Issuing Lender of the date and amount of a draft presented under any Letter of Credit and paid by the Issuing Lender, for the amount of (i) such draft so paid and (ii) any taxes, fees, charges or other costs or expenses incurred by the Issuing Lender in connection with such payment. Except as and to the extent otherwise provided in subsection 4.5(c), each such payment shall be made to the Issuing Lender, at its address for notices specified herein in Canadian Dollars and in 71

immediately available funds, on the date on which the Borrower receives such notice, if received prior to 11:00 A.M., Toronto time, on a Business Day and otherwise on the next succeeding Business Day. (b) Interest shall be payable on any and all amounts payable under subsection 4.5(a) and remaining unpaid by the Borrower (i) from the date the draft presented under the affected Letter of Credit is paid to the earlier of the third Business Day after the date on which the Borrower is required to pay such amounts pursuant to subsection 4.5(a) and the date on which the Borrower pays all such amounts at the rate which would then be payable on any outstanding Prime Rate Loans and (ii) thereafter until payment in full at the rate which would be payable on any outstanding Prime Rate Loans which were then overdue. (c) By 12:00 P.M., Toronto time, on the first Business Day after each date on which a draft is presented under any Letter of Credit and paid by the Issuing Lender, the Administrative Agent shall, on behalf of the Borrower (which hereby irrevocably directs and authorizes the Administrative Agent to act on its behalf), request (in accordance with the applicable provisions of subsection 2.3) each Lender to make a Revolving Credit Loan in an amount equal to such Lender's Commitment Percentage of the amount of such draft so paid. Each Lender agrees to make each Revolving Credit Loan so requested available to the Administrative Agent in accordance with subsection 2.3, provided that the -------- conditions precedent contained in subsection 7.2 to its obligation to make such Revolving Credit Loan have been satisfied. The proceeds of such Revolving Credit Loans shall be made available by the Administrative Agent to the Issuing Lender and applied to the payment (whether or not then due) of the obligations of the Borrower under subsection 4.5(a)(i); upon such payment, the Borrower shall be deemed to have satisfied such obligations to the extent of such payment. The Issuing Lender shall notify the Administrative Agent and the Borrower as soon as reasonably practicable of each drawing 72

made under a Letter of Credit and the aggregate principal amount of the Revolving Credit Loans made under this subsection 4.5(c) in respect thereof. 4.6 Obligations Absolute. (a) The Borrower's obligations under this -------------------- Section 4 shall be absolute and unconditional under any and all circumstances and irrespective of any set-off, counterclaim or defense to payment which the Borrower may have or have had against the Issuing Lender or any beneficiary of a Letter of Credit, provided that this paragraph shall not relieve the Issuing -------- Lender of any liability resulting from the gross negligence or willful misconduct of the Issuing Lender, or otherwise affect any defense or other right that the Borrower may have as a result of any such gross negligence or willful misconduct. (b) The Borrower also agrees with the Issuing Lender that the Issuing Lender shall not be responsible for, and the Borrower's Reimbursement Obligations under subsection 4.5(a) shall not be affected by, among other things, (i) the validity or genuineness of documents or of any endorsements thereon, even though such documents shall in fact prove to be invalid, fraudulent or forged, or (ii) any dispute between or among the Borrower and any beneficiary of any Letter of Credit or any other party to which such Letter of Credit may be transferred or (iii) any claims whatsoever of the Borrower against any beneficiary of such Letter of Credit or any such transferee, provided that -------- this paragraph shall not relieve the Issuing Lender of any liability resulting from the gross negligence or willful misconduct of the Issuing Lender, or otherwise affect any defense or other right that the Borrower may have as a result of any such gross negligence or willful misconduct. (c) The Issuing Lender shall not be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit, except 73

for errors or omissions caused by the Issuing Lender's gross negligence or willful misconduct. (d) The Borrower agrees that any action taken or omitted by the Issuing Lender under or in connection with any Letter of Credit or the related drafts or documents, if done in the absence of gross negligence or willful misconduct and in accordance with the standards of care specified in the Uniform Customs, shall be binding on the Borrower and shall not result in any liability of the Issuing Lender to the Borrower. 4.7 Letter of Credit Payments. If any draft shall be presented for ------------------------- payment under any Letter of Credit, the Issuing Lender shall promptly notify the Borrower, the Swing Line Lender and the Administrative Agent of the date and amount thereof. The responsibility of the Issuing Lender to the Borrower in connection with any draft presented for payment under any Letter of Credit shall, in addition to any payment obligation expressly provided for in such Letter of Credit, be limited to determining that the documents (including each draft) delivered under such Letter of Credit in connection with such presentment are in conformity with such Letter of Credit, provided that this paragraph shall -------- not relieve the Issuing Lender of any liability resulting from the gross negligence or willful misconduct of the Issuing Lender, or otherwise affect any defense or other right that the Borrower may have as a result of any such gross negligence or willful misconduct. 4.8 Application. To the extent that any provision of any Application ----------- related to any Letter of Credit is inconsistent with the provisions of this Section 4, the provisions of this Section 4 shall apply. 74

SECTION 5. GENERAL PROVISIONS APPLICABLE TO LOANS AND LETTERS OF CREDIT 5.1 Interest Rates and Payment Dates. (a) Each Prime Rate Loan -------------------------------- (including each Swing Line Loan) shall bear interest for each day that it is outstanding at a rate per annum equal to the Prime Rate for such day plus the Prime Rate Margin in effect for such day. (b) If all or a portion of (i) the principal amount of any Loan, (ii) any interest payable thereon or (iii) any commitment fee or other amount payable hereunder shall not be paid when due (whether at the stated maturity, by acceleration or otherwise), such overdue amount shall bear interest at a rate per annum which is (x) in the case of overdue principal, the rate that would otherwise be applicable thereto pursuant to the foregoing provisions of this subsection plus 2% or (y) in the case of overdue interest, commitment fee or other amount, the rate described in paragraph (a) of this subsection plus 2%, in each case from the date of such non-payment until such amount is paid in full (as well after as before judgment).

(a) The Borrower may at any ---------------------------------- time and from time to time repay the Loans, in whole or in part, without premium or penalty, upon irrevocable notice given to the Administrative Agent no later than 12:00 P.M., Toronto time on the immediately preceding Business Day specifying the date and amount of repayment and whether the repayment is of Revolving Credit Loans or Swing Line Loans or a combination thereof, and, in each case if a combination thereof, the amount allocable to each.

(d) The Borrower shall prepay all Swing Line Loans then outstanding simultaneously with each borrowing of Revolving Credit Loans and may prepay (without premium or penalty) any outstanding Swing Line Loans upon at least one Business Day's notice to the Administrative Agent. 5.3 Commitment Fees; Agency Fees; Other Fees. (a) The Borrower ---------------------------------------- agrees to pay to the Administrative Agent for the account of each Lender, a commitment fee for the period from and including the Closing Date to but excluding the Termination Date (or such earlier date as the Commitments shall terminate as provided herein), computed at the Commitment Fee Rate on the average daily amount of the Available Commitment of such Lender during the period for which payment is made, payable quarterly in arrears on the last day of each March, June, September and December and on the Termination Date or such earlier date as the Commitments shall terminate as provided herein, commencing on the first such date to occur after the date hereof. (b) The Borrower shall pay (without duplication of any fee payable under subsection 5.3(a)) to the Administrative Agent and the Collateral Agent, for their respective accounts, the other fees required to be paid pursuant to the Agency Fee Letter, dated February 24, 1995 between the U.S. Borrower, the U.S. Administrative Agent and the U.S. Collateral Agent, in each case in the amounts and on the dates set forth therein. 5.4 Computation of Interest and Fees. (a) Interest based on the -------------------------------- Prime Rate and commitment fees and interest (other than the interest component of the Reference Discount Rate) shall be calculated on the basis of a 365-(or 366-, as the case may be) day year for the actual days elapsed. Any change in the interest rate on a Loan resulting from a change in the Prime Rate shall become effective as of the opening of business on the day on which such change becomes effective. The Administrative Agent shall as soon as practicable notify the Borrower and the 78

Lenders of the effective date and the amount of each such change in interest rate. (b) For purposes of the Interest Act, (i) the principle of deemed reinvestment of interest does not apply to any interest calculation under this Agreement; and (ii) the rates of interest stipulated in this Agreement are intended to be nominal rates and not effective rates or yields. (c) Each determination of an interest rate by the Administrative Agent pursuant to any provision of this Agreement shall be conclusive and binding on the Borrower and the Lenders in the absence of manifest error. The Administrative Agent shall, at the request of the Borrower, deliver to the Borrower a statement showing in reasonable detail the calculations used by the Administrative Agent in determining any interest rate pursuant to subsection 5.1. 5.5 Pro Rata Treatment and Payments. (a) Except as provided in ------------------------------- subsection 2.4(b) and (c), each borrowing of Loans (other than Swing Line Loans) by the Borrower from the Lenders hereunder shall be made, each payment by the Borrower on account of any commitment fee hereunder shall be allocated by the Administrative Agent, and any reduction of the Commitments of the Lenders shall be allocated by the Administrative Agent, pro rata according to the relevant --- ---- Commitment Percentages of the Lenders. Except as provided in subsection 2.4(c), each payment (including each prepayment) by the Borrower on account of principal of and interest on any Revolving Credit Loans shall be allocated by the Administrative Agent pro rata according to the respective outstanding principal --- ---- amounts of such Revolving Credit Loans then held by the Lenders. All payments (including prepayments) to be made by the Borrower hereunder and under any Notes, whether on account of principal, interest, fees or otherwise, shall be made without set-off or counterclaim and shall be made prior to 12:00 P.M., Toronto time, on the due date thereof to the Administrative Agent, for the account of the Lenders holding such Notes, at the Administrative Agent's office specified in subsection 12.2, in Canadian Dollars and in immediately available funds. The Administrative Agent shall distribute such payments to such Lenders, if any such payment is received prior to 12:00 Noon, Toronto time, on a Business Day, in like funds as received prior to the end of such Business Day, and otherwise the 79

Administrative Agent shall distribute such payment to such Lenders on the next succeeding Business Day. If any payment hereunder (other than payments on the Acceptances) becomes due and payable on a day other than a Business Day, the maturity of such payment shall be extended to the next succeeding Business Day, and, with respect to payments of principal, interest thereon shall be payable at the then applicable rate during such extension. (b) Unless the Administrative Agent shall have been notified in writing by any Lender prior to a borrowing that such Lender will not make the amount that would constitute its share of such borrowing available to the Administrative Agent, the Administrative Agent may assume that such Lender is making such amount available to the Administrative Agent, and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower a corresponding amount. If such amount is not made available to the Administrative Agent by the required time on the Borrowing Date therefor, such Lender shall pay to the Administrative Agent, on demand, such 80

amount with interest thereon at a rate equal to the Administrative Agent's reasonable estimate of its daily average cost of funds for the period until such Lender makes such amount immediately available to the Administrative Agent. A certificate of the Administrative Agent submitted to any Lender with respect to any amounts owing under this subsection shall be conclusive in the absence of manifest error. If such Lender's share of such borrowing is not made available to the Administrative Agent by such Lender within three Business Days of such Borrowing Date, (x) the Administrative Agent shall notify the Borrower of the failure of such Lender to make such amount available to the Administrative Agent and the Administrative Agent shall also be entitled to recover such amount with interest thereon at the rate per annum applicable to Prime Rate Loans hereunder, on demand, from the Borrower and (y) the Borrower may, without waiving any rights it may have against such Lender, borrow a like amount on an unsecured basis from any commercial bank for a period ending on the date upon which such Lender does in fact make such borrowing available, provided that (i) at the time -------- such borrowing is made and at all times while such amount is outstanding the Borrower would be permitted to borrow such amount pursuant to subsection 2.1 of this Agreement and (ii) the commercial bank from whom such borrowing is made waives in a written agreement reasonably satisfactory to the Administrative Agent any right of set-off it may have against the Collateral. 5.6 Borrowing Base Compliance. The Collateral Agent or another ------------------------- financial institution satisfactory to the Collateral Agent (including any Affiliate of the Collateral Agent) shall, from time to time during the Commitment Period, (except during any Borrowing Base Elimination Period) review and confirm the information set forth in each Monthly Borrowing Base Certificate delivered by the Borrower in order to determine whether, at such time, the Borrower is in compliance with the requirements in respect of the Borrowing Base under this Agreement, and the Borrower shall reimburse the Collateral Agent for its reasonable out-of-pocket expenses (excluding fees) in respect thereof. If the Borrower is not in compliance with such requirements, the Collateral Agent shall promptly notify the Borrower, the Administrative Agent and the Lenders of such noncompliance, and the Borrower shall make all mandatory prepayments required pursuant to subsection 5.2(b). 5.7 Illegality. Notwithstanding any other provision herein, if the ---------- adoption of or any change in any Requirement of Law or in the interpretation or application thereof occurring after the date hereof shall make it unlawful for any Lender to create or maintain Acceptances as contemplated by this Agreement, (a) such Lender shall as soon as reasonably practicable thereafter give written 81

notice of such circumstances to the Borrower and the Administrative Agent (which notice shall be withdrawn whenever such circumstances no longer exist), (b) the commitment of such Lender hereunder to accept Drafts, purchase Acceptances and convert Prime Rate Loans to Acceptances shall forthwith be cancelled, and, until such time as it shall no longer be unlawful for such Lender to create or maintain Acceptances, such Lender shall then have a commitment only to make a Prime Rate Loan when an Acceptance is requested and (c) all outstanding Acceptances, if any, shall be converted automatically to Prime Rate Loans on the respective maturities thereof or within such earlier period as required by law. 5.8 Requirements of Law. (a) If the adoption of or any change in ------------------- any Requirement of Law or in the interpretation or application thereof applicable to any Lender, or compliance by any Lender with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority, in each case made subsequent to the date hereof (or, if later, the date on which such Lender becomes a Lender): (i) shall subject such Lender to any tax of any kind whatsoever with respect to this Agreement, any Note, any Letter of Credit, any Application or any Acceptance made by it, or change the basis of taxation of payments to such Lender in respect thereof (except for Non-Excluded Taxes covered by subsection 5.9 (including Non-Excluded Taxes imposed solely by reason of any failure of such Lender to comply with its obligations under subsection 5.9(a)) and changes in rate of tax on the overall net income, or franchise tax (imposed in lieu of such net income tax), of such Lender or its applicable lending office, branch, or any affiliate thereof); (ii) shall impose on such Lender any other condition (excluding any tax of any kind whatsoever); 82

and the result of any of the foregoing is to increase the cost to such Lender, by an amount which such Lender deems to be material, of creating, converting into, continuing or maintaining Acceptances or issuing or participating in Letters of Credit or to reduce any amount receivable hereunder in respect thereof, then, in any such case, upon notice to the Borrower from such Lender, through the Administrative Agent, in accordance herewith, the Borrower shall promptly pay such Lender, upon its demand, any additional amounts necessary to compensate such Lender for such increased cost or reduced amount receivable, provided that, in any such case, the Borrower may elect to convert any - -------- Acceptances made available by such Lender hereunder to Prime Rate Loans by cash collateralizing all outstanding Acceptances and by giving the Administrative Agent at least three Business Days' notice of such election. If any Lender becomes entitled to claim any additional amounts pursuant to this subsection, it shall as soon as reasonably practicable thereafter provide notice thereof to the Borrower, through the Administrative Agent, certifying (x) that one of the events described in this paragraph (a) has occurred and describing in reasonable detail the nature of such event, (y) as to the increased cost or reduced amount resulting from such event and (z) as to the additional amount demanded by such Lender and a reasonably detailed explanation of the calculation thereof. Such a certificate as to any additional amounts payable pursuant to this subsection submitted by such Lender, through the Administrative Agent, to the Borrower shall be conclusive in the absence of manifest error. This covenant shall survive the termination of this Agreement and the payment of the Notes and all other amounts payable hereunder. (b) If any Lender shall have determined that the adoption of or any change in any Requirement of Law regarding capital adequacy or in the interpretation or application thereof or compliance by such Lender or any corporation controlling such Lender with any request or directive regarding capital adequacy (whether or not having the force of law) from any Governmental Authority, in each 83

case, made subsequent to the date hereof (or, if later, the date on which such Lender becomes a Lender), does or shall have the effect of reducing the rate of return on such Lender's or such corporation's capital as a consequence of its obligations hereunder or under any Letter of Credit to a level below that which such Lender or such corporation could have achieved but for such change or compliance (taking into consideration such Lender's or such corporation's policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, within ten Business Days after submission by such Lender to the Borrower (with a copy to the Administrative Agent) of a written request therefor certifying (x) that one of the events described in this paragraph (b) has occurred and describing in reasonable detail the nature of such event, (y) as to the reduction of the rate of return on capital resulting from such event and (z) as to the additional amount or amounts demanded by such Lender and a reasonably detailed explanation of the calculation thereof, the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender for such reduction. 5.9 Taxes. (a) Except as provided below in this subsection, all ----- payments made by the Borrower under this Agreement and the Notes shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any Governmental Authority, excluding in the case of each Lender or its applicable lending office, or any branch or affiliate thereof (i) net income taxes, doing business and franchise and similar taxes, branch taxes or taxes on the overall capital or net worth of any Lender or its applicable lending office, or any branch or affiliate thereof imposed by any jurisdiction under the laws of which such Lender, applicable lending office, branch or affiliate is organized or is located, or in which its principal executive office is located, or any nation within which such jurisdiction is located or any political subdivision thereof 84

and (ii) any such taxes or other tax, levy, impost, duty, charge, fee, deduction or withholding imposed by reason of any connection between the jurisdiction imposing such tax and such Lender, applicable lending office, branch or affiliate other than a connection arising solely from such Lender having executed, delivered or performed its obligations, or received payment under or enforced, this Agreement or the Notes. If any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or withholdings ("Non-Excluded ------------ Taxes") are required to be withheld from any amounts payable to the - ------ Administrative Agent or any Lender hereunder or under the Notes, the amounts so payable to the Administrative Agent or such Lender shall be increased by any additional amounts to the extent necessary to yield to the Administrative Agent or such Lender (after payment of all Non-Excluded Taxes on such additional amounts) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement and the Notes; provided, however, that -------- the Borrower shall be entitled to deduct and withhold any Non-Excluded Taxes and shall not be required to pay any such additional amounts to any Lender that is not incorporated under the laws of Canada or a province thereof or is not a resident of Canada for purposes of the Tax Act. Whenever any Non-Excluded Taxes are payable by the Borrower, as promptly as possible thereafter, the Borrower shall send to the Administrative Agent for its own account or for the account of such Lender, as the case may be, a certified copy of an original official receipt received by the Borrower showing payment thereof. If the Borrower fails to pay any Non-Excluded Taxes when due to the appropriate taxing authority or fails to remit to the Administrative Agent the required receipts or other required documentary evidence, the Borrower shall indemnify the Administrative Agent and each Lender from any incremental taxes, interest or penalties that may become payable by the Administrative Agent or any Lender as a result of any such failure. The agreements in this subsection 5.9 shall survive the termination of this Agreement and the payment of the Loans, 85

Acceptance Reimbursement Obligations, Letters of Credit and all other amounts payable hereunder. (b) Any Lender that is not incorporated under the laws of Canada or a province thereof or is not a resident of Canada for purposes of the Tax Act shall, on or before the date of any payment by the Borrower under this Agreement, notify the Borrower and the Administrative Agent in writing of the jurisdiction in which the Lender is resident. 5.10 Certain Rules Relating to the Payment of Additional Amounts. ----------------------------------------------------------- (a) Upon the request, and at the expense, of the Borrower, each Lender to which the Borrower is required to pay any additional amount pursuant to subsection 5.8 or 5.9, and any Participant in respect of whose participation such payment is required, shall reasonably afford the Borrower the opportunity to contest, and reasonably cooperate with the Borrower in contesting, the imposition of any Non- Excluded Tax giving rise to such payment; provided that (i) such Lender shall -------- not be required to afford the Borrower the opportunity to so contest unless the Borrower shall have confirmed in writing to such Lender its obligation to pay such amounts pursuant to this Agreement and (ii) the Borrower shall reimburse such Lender for its reasonable attorneys' and accountants' fees and disbursements incurred in so cooperating with the Borrower in contesting the imposition of such Non-Excluded Tax. (b) If a Lender changes its applicable lending office (other than pursuant to paragraph (c) below) and the effect of the change, as of the date of the change, would be to cause the Borrower to become obligated to pay any additional amount under subsection 5.8 or 5.9, the Borrower shall not be obligated to pay such additional amount. (c) If a condition or an event occurs which would, or would upon the passage of time or giving of notice, result in the payment of any additional amount to any Lender by the Borrower pursuant to subsection 5.8 or 5.9, such Lender shall as soon as reasonably practicable 86

thereafter notify the Borrower and the Administrative Agent and shall take such steps as may reasonably be available to it and acceptable to the Borrower to mitigate the effects of such condition or event (which shall include efforts to rebook the Loans held by such Lender at another lending office, or through another branch or an affiliate, of such Lender); provided that such Lender shall -------- not be required to take any step that, in its reasonable judgment, would be materially disadvantageous to its business or operations or would require it to incur additional costs (unless the Borrower agrees to reimburse such Lender for all such reasonable and actual additional costs). (d) If (and for so long as) the Borrower shall become obligated to pay additional amounts pursuant to subsection 5.8 or 5.9 and any affected Lender shall not have promptly taken the steps necessary to avoid the need for payments under subsection 5.8 or 5.9, the Borrower shall have the right, upon payment in full of all amounts then due from it under subsections 5.8 and 5.9, (i) with the assistance of the Administrative Agent, to seek one or more substitute Lenders reasonably satisfactory to the Administrative Agent and the Borrower to purchase in accordance with the provisions of subsection 12.6(c) the affected Loan, in whole or in part, at an aggregate price no less than the principal amount of such Loan or part thereof being purchased plus accrued and unpaid interest thereon to the date of purchase and all fees and other amounts owing to the affected Lender hereunder (or under the other Loan Documents) and accrued to the date of the purchase (but without payment to the affected Lender of any premium or penalty) and to assume the obligations of the affected Lender under this Agreement and the other Loan Documents, or (ii) after the Borrower has made a good faith effort to seek a substitute Lender in accordance with clause (i) above and provided that no Default or Event of Default has occurred and is continuing, upon at least three Business Days' irrevocable notice to the Administrative Agent and the affected Lender, to terminate the entire Commitment of the affected Lender and to repay the affected Loan, together 87

with accrued and unpaid interest thereon to date of repayment, and all fees and other amounts accrued to the date of repayment and owing to the affected Lender hereunder (or under the other Loan Documents) (but without payment to the affected Lender of any premium or penalty). In the case of the substitution of a Lender, the Borrower, the Administrative Agent, the affected Lender, and any substitute Lender shall execute and deliver an appropriately completed Assignment and Acceptance pursuant to subsection 12.6(c) to effect the assignment of rights to, and the assumption of obligations by, the substitute Lender. (e) Notwithstanding any other provision of this Agreement, no Lender shall be entitled to receive any additional amounts pursuant to subsection 5.8 or 5.9 unless such Lender represents to the Borrower that, at the time of any request by such Lender that such amounts be paid, it is the policy or general practice of such Lender to demand such compensation for comparable costs or deductions, if any, in similar circumstances, if any, under comparable provisions of other credit agreements for comparable customers. (f) The obligations of the Borrower and a Lender or Participant under this subsection 5.10 shall survive the termination of this Agreement and the payment of the Notes and all amounts payable. SECTION 6.

The execution, delivery and performance of the ------------ Loan Documents to which the Borrower is a party, the borrowings hereunder and the use of the proceeds thereof and the creation and perfection of the Liens contemplated by the Security Agreements (a) will not violate any Requirement of Law or Contractual Obligation of the 90

Except as expressly provided above in this Section, presentment, demand, protest and all other notices of any kind are hereby expressly waived. SECTION 11. THE AGENT 11.1 Appointment. Each Lender hereby irrevocably designates and ----------- appoints (i) Bank of Nova Scotia as the Administrative Agent and (ii) Barclays as Collateral Agent of such Lender hereunder and under the other Loan Documents. The term "Agent", when used in this Section 11, shall refer to each of (i) Bank of Nova Scotia in its capacity as Administrative Agent and (ii) Barclays in its capacity as Collateral Agent. Each such Lender irrevocably authorizes Bank of Nova Scotia to act as Administrative Agent and Barclays to act as Collateral Agent of such Lender, to take such action on its behalf under the provisions of this Agreement and the other Loan Documents and to exercise such powers and perform such duties as are expressly delegated to it as Agent by the terms of this Agreement and the other Loan Documents, together with such other powers as are reasonably incidental thereto. For greater certainty and without limiting the powers of the Administrative Agent herein, and solely for the purposes of constituting security on any property located in the Province of Quebec (including, without limitation, the Quebec Moveable Hypothec), the Borrower, each Lender and the Administrative Agent hereby acknowledge that the Administrative Agent shall 116

be the holder of a power of attorney for the Lenders, and the Administrative Agent accepts such appointment. The execution of an Assignment and Acceptance by any Assignee pursuant to Section 12.6 hereof shall constitute ratification of the power of attorney constituted hereby. Notwithstanding any provision to the contrary elsewhere in this Agreement, neither Agent shall have any duties or responsibilities, except those expressly set forth herein, or any fiduciary relationship with any Lender, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against either Agent. Each Lender acknowledges and consents (i) that the U.S. Administrative Agent is an Affiliate of the Administrative Agent, (ii) the Collateral Agent is also acting as U.S. Collateral Agent and (iii) to the appointment by the Administrative Agent of the U.S. Collateral Agent to act on its behalf and on behalf of the Lenders under the U.S. Security Documents (other than the U.S. Borrower Canadian Stock Pledge Agreement). 11.2 Delegation of Duties. Each Agent may execute any or all of its -------------------- duties under this Agreement and the other Loan Documents by or through agents (which may include its Affiliates or attorneys-in-fact) and shall be entitled to advice of counsel concerning all matters pertaining to such duties. For the purposes of this Section 11 and all subsections thereof the word "Agent" shall be deemed to include any Affiliate or attorney-in-fact thereof. Neither Agent shall be responsible for the negligence or misconduct of any agents or attorneys-in-fact selected by it with reasonable care. 11.3 Exculpatory Provisions. Neither Agent nor any officer, ---------------------- director, employee, agent, attorney-in-fact or Affiliate of either Agent shall be (i) liable for any action lawfully taken or omitted to be taken by it or such Person under or in connection with this Agreement or any other Loan Document (except for its or such Person's gross negligence or willful misconduct) or (ii) responsible in any manner to 117

any of the Lenders for any recitals, statements, representations or warranties made by any Loan Party or any officer thereof contained in this Agreement or any other Loan Document or in any certificate, report, statement or other document referred to or provided for in, or received by either Agent under or in connection with, this Agreement or any other Loan Document or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or the Notes or any other Loan Document or for any failure of the Borrower or any other Loan Party to perform its obligations hereunder or thereunder. Neither Agent shall be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of the Borrower or any other Loan Party. 11.4 Reliance by Agent. Each Agent shall be entitled to rely, and ----------------- shall be fully protected in relying, upon any Note, writing, resolution, notice, consent, certificate, affidavit, letter, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including, without limitation, counsel to the Borrower), independent accountants and other experts selected by such Agent. Each Agent may deem and treat the payee of any Note as the owner thereof for all purposes unless a written notice of assignment or transfer thereof shall have been filed with the Administrative Agent. Each Agent shall be fully justified as between itself and the Lenders in failing or refusing to take any action under this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the requisite Lenders (and, if applicable, the requisite U.S. Lenders) as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking 118

or continuing to take any such action. Each Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the Notes and the other Loan Documents in accordance with a request of the requisite Lenders, and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and all future holders of the Notes. 11.5 Notice of Default. Neither Agent shall be deemed to have ----------------- knowledge or notice of the occurrence of any Default or Event of Default hereunder or of a U.S. Default or a U.S. Event of Default under the U.S. Credit Agreement unless such Agent has received notice from a Lender or the Borrower referring to this Agreement, describing such Default or Event of Default or U.S. Default or U.S. Event of Default and stating that such notice is a "notice of default". In the event that an Agent receives such a notice, such Agent shall give notice thereof to the Lenders. Each Agent shall take such action reasonably promptly with respect to such Default or Event of Default or U.S. Default or U.S. Event of Default as shall be reasonably directed by the Majority Lenders; provided that unless and until such Agent shall have received such directions, - -------- such Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Lenders; and provided, further, that in the case of any U.S. Default or U.S. Event of Default such Agent shall be entitled to take such action provided for under the applicable U.S. Loan Documents. 11.6 Non-Reliance on Agent and Other Lenders. Each Lender expressly --------------------------------------- acknowledges that neither Agent nor any officer, director, employee, agent, attorney-in-fact or Affiliate of either Agent has made any representations or warranties to it and that no act by either Agent hereinafter taken, including any review of the affairs of the Borrower or any other Loan Party, shall be deemed to constitute any representation or warranty by such Agent to any Lender. Each Lender represents to each Agent that it has, 119

independently and without reliance upon either Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other condition and creditworthiness of the Borrower and the other Loan Parties and made its own decision to make its Loans hereunder and enter into this Agreement. Each Lender also represents that it will, independently and without reliance upon either Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, financial and other condition and creditworthiness of the Borrower and the other Loan Parties. Except for notices, reports and other documents expressly required to be furnished to the Lenders by an Agent hereunder, such Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, condition (financial or otherwise), prospects or creditworthiness of the Borrower or any other Loan Party which may come into the possession of such Agent or any of its respective officers, directors, employees, agents, attorneys-in-fact or Affiliates. 11.7 Indemnification. Each Lender agrees to indemnify each Agent in --------------- its respective capacities as such (to the extent not reimbursed by the Borrower and without limiting the obligation of the Borrower or any other Loan Party to do so), ratably according to its Commitment Percentage in effect on the date on which indemnification is sought under this subsection (or, if indemnification is sought after the date upon which the Commitments shall have terminated and the Loans, Reimbursement Obligations and Acceptance Reimbursement Obligations shall have been paid in full, ratably in accordance with its Commitment Percentage immediately prior to such date), from and against any and all liabilities, obligations, losses, damages, penalties, 120

actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever which may at any time (including, without limitation, at any time following the payment of the Notes) be imposed on, incurred by or asserted against such Agent in any way relating to or arising out of this Agreement, any of the other Loan Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by such Agent under or in connection with any of the foregoing; provided that no Lender shall be liable for the payment of any -------- portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting solely from the gross negligence or willful misconduct of such Agent. The agreements in this subsection shall survive the payment of the Notes and all other amounts payable hereunder. 11.8 Agent in Its Individual Capacity. Each Agent and its Affiliates -------------------------------- may make loans to, accept deposits from and generally engage in any kind of business with the Borrower and/or the other Loan Parties as though such Agent was not an Agent hereunder and under the other Loan Documents. With respect to the Loans made or renewed by an Agent and any Note issued to it and with respect to any Acceptance completed and accepted by it or any Letter of Credit issued or participated in by it, such Agent shall have the same rights and powers under this Agreement and the other Loan Documents as any Lender and may exercise the same as though it were not an Agent, and the terms "Lender" and "Lenders" shall include such Agent in its individual capacity. 11.9 Successor Agent. Each of the Administrative Agent and the --------------- Collateral Agent may resign as such upon 30 days' notice to the Lenders. If an Agent shall resign as Administrative Agent or Collateral Agent (as applicable) under this Agreement and the other Loan Documents, then the Majority Lenders shall appoint from among the Lenders a successor agent for the Lenders, which successor agent shall 121

be approved by the Borrower, whereupon such successor agent shall succeed to the rights, powers and duties of the resigning Administrative Agent or Collateral Agent (as applicable), and the term "Administrative Agent" or "Collateral Agent" (as applicable) shall mean such successor agent effective upon such appointment and approval, and the former Agent's rights, powers and duties as Administrative Agent or Collateral Agent (as applicable) shall be terminated, without any other or further act or deed on the part of such former Agent or any of the parties to this Agreement or any holders of the Notes; provided that the resigning Agent -------- shall execute all documents which the replacement Agent deems reasonably necessary or advisable to effect such substitution. After any resigning Agent's resignation as Administrative Agent or Collateral Agent (as applicable), the provisions of this subsection shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent or Collateral Agent (as applicable) under this Agreement and the other Loan Documents. 11.10 Swing Line Lender. The provisions of this Section 11 shall ----------------- apply to the Swing Line Lender in its capacity as such to the same extent that such provisions apply to the Agent. 11.11 Co-Agents. Each party hereto agrees that the Co-Agents have no --------- rights or obligations hereunder or under the other Credit Documents in their respective capacities as such. SECTION 12. MISCELLANEOUS 12.1 Amendments and Waivers. Neither this Agreement, any Note or any ---------------------- other Loan Document, nor any terms hereof or thereof may be amended, supplemented or modified except in accordance with the provisions of this subsection 12.1. The Majority Lenders may, or, with the written consent of the Majority Lenders, the Administrative 122

in the definition of "Borrowing Base", in each case without the written consent of all the Lenders; (iii) release all or substantially all of the Collateral without the consent of the Supermajority Lenders; (iv) amend, supplement, modify or waive any provision of Section 11 or any other provision of this Agreement governing the rights or obligations of the Administrative Agent and the Collateral Agent without the written consent of the then Administrative Agent and the then Collateral Agent; (v) amend, supplement, modify or waive (a) the order of application of prepayments specified in subsection 5.2 without the consent of the Swing Line Lender and each Lender adversely affected thereby or (b) any provision of any Principal Loan Document which specifies the order of application by the Administrative Agent of proceeds of Collateral upon the occurrence and during the continuance of an Event of Default without the consent of the Administrative Agent, the Collateral Agent and each Lender; (vi) amend, supplement, modify or waive any provision of the Swing Line Note or of subsection 2.5 or any other provision of this Agreement governing the rights and obligations of the Swing Line Lender or the definitions used therein without the written consent of the Swing Line Lender and, in the case of the Swing Line Note, each Lender, if any, which holds a participation therein pursuant to subsection 2.5(d); and (vii) amend, supplement, modify or waive any provision of the Letters of Credit, the Applications relating thereto and the L/C Obligations or of Section 4 or any other provision of this Agreement governing the rights and obligations of the Issuing Lender or the 124

definitions used therein without the written consent of the Issuing Lender, and, in the case of the Letters of Credit and the L/C Obligations, each affected L/C Participant. Any waiver and any amendment, supplement, modification or waiver pursuant to this subsection 12.1 shall apply to each of the Lenders and shall be binding upon the Borrower, the other Loan Parties, the Lenders, the Administrative Agent, the Collateral Agent and all future holders of the Notes. In the case of any waiver, the Borrower, the other Loan Parties, the Lenders, the Collateral Agent and the Administrative Agent shall be restored to their former position and rights hereunder and under the outstanding Notes and any other Loan Documents, and any Default or Event of Default waived shall be deemed to be cured and not continuing; but no such waiver shall extend to any subsequent or other Default or Event of Default, or impair any right consequent thereon. Each Loan Document (other than the Principal Loan Documents) may be amended, supplemented, modified or waived only in accordance with the provisions of subsection 11.1 of the U.S. Credit Agreement. 12.2 Notices. All notices, requests and demands to or upon the ------- respective parties hereto to be effective shall be in writing (including by telecopy), and, unless otherwise expressly provided herein, shall be deemed to have been duly given or made when delivered by hand, or three days after being deposited in the mail, postage prepaid, or, in the case of telecopy notice, when received, or, in the case of delivery by a nationally recognized overnight courier, when received, addressed as follows in the case of the Borrower, the Collateral Agent or the Administrative Agent and as set forth in Schedule 1 hereto in the case of the other parties hereto, or to such other address as may be hereafter notified by the respective parties hereto and any future holders of the Notes: 125

(a) ------------------------------------------------------ This Agreement shall be binding upon and inure to the benefit of the Borrower, the Lenders, the Administrative Agent, the Collateral Agent, all future holders of the Notes and their respective successors and permitted assigns, except that the Borrower may not assign or transfer any of its rights or obligations under this Agreement without the prior written consent of each Lender. (b) Any Lender may, in the ordinary course of its commercial banking business and in accordance with applicable law, at any time sell to one or more banks or other entities ("Participants") participating interests in any Loan ------------ owing to such Lender, any Note held by such Lender, any Commitment of such Lender or any other interest of such Lender hereunder and under the other Loan Documents, provided that such Participant shall be a Qualifying Canadian -------- Institution. In the event of any such sale by a Lender of a participating interest to a Participant, such Lender's obligations under this Agreement to the other parties to this Agreement shall remain unchanged, such Lender shall remain solely responsible for the performance thereof, such Lender shall remain the holder of any such Note for all purposes under this Agreement and the other Loan Documents, and the Borrower, the Collateral Agent and the Administrative Agent shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under this Agreement and the other Loan Documents. Any agreement pursuant to which any Lender shall sell any such participating interest shall provide that such Lender shall retain the sole right and responsibility to exercise such Lender's rights and enforce 130

the Borrower's obligations hereunder, including the right to consent to any amendment, supplement, modification or waiver of any provision of this Agreement or any of the other Loan Documents, provided that such participation agreement -------- may provide that such Lender will not agree to any amendment, supplement, modification or waiver described in clause (i) or (ii) of the proviso to the second sentence of subsection 12.1 without the consent of the Participant. The Borrower agrees that if amounts outstanding under this Agreement and the Notes are due or unpaid, or shall have been declared or shall have become due and payable upon the occurrence of an Event of Default, each Participant shall be deemed to have the right of setoff in respect of its participating interest in amounts owing under this Agreement and any Note to the same extent as if the amount of its participating interest were owing directly to it as a Lender under this Agreement or any Note, provided that, in purchasing such participating -------- interest, such Participant shall be deemed to have agreed to share with the Lenders the proceeds thereof as provided in subsection 12.7(a) as fully as if it were a Lender hereunder. The Borrower agrees that each Lender shall be entitled to the benefits of subsections 5.7, 5.8 and 5.9 and 12.1 without regard to whether it has granted any participating interests, and that all amounts payable to a Lender under subsections 5.7, 5.8 and 5.9 shall be determined as if such Lender had not granted any such participating interests. (c) Any Lender may, in the ordinary course of its commercial banking business and in accordance with applicable law, at any time and from time to time assign to any Lender, or any Affiliate thereof or, with the prior written consent of the Borrower and the Administrative Agent, to an additional bank or financial institution (an "Assignee") all or any part of its rights and -------- obligations under this Agreement and the Notes, including, without limitation, its Commitments, L/C Obligations, Acceptances, Acceptance Notes and Loans, pursuant to an Assignment and Acceptance, substantially in the form of Exhibit F, executed by such Assignee, such assigning Lender (and, in the case of 131

an Assignee that is not then a Lender, a U.S. Lender or an Affiliate thereof, by the Borrower and the Administrative Agent) and delivered to the Administrative Agent for its acceptance and recording in the Register; provided that (i) the -------- Assignee is a Qualifying Canadian Institution, (ii) in the case of any such transfer of the full amount of such assigning Lender's Commitment to an additional bank or financial institution, the consent of the Administrative Agent and the Borrower shall not be unreasonably withheld, (iii) if any Lender assigns all or any part of its rights and obligations under this Agreement to one of its Affiliates in connection with or in contemplation of the sale of its interest in such Affiliate, the Borrower's prior written consent (not to be unreasonably withheld) shall be required for such assignment and (iv) if any Lender assigns a part of its rights and obligations under this Agreement to an Assignee, such Lender shall assign proportionate interests in its Commitment, Revolving Credit Loans, Acceptances, Acceptance Notes, L/C Obligations, participations in Swing Line Loans and Letters of Credit and other rights and obligations hereunder to such Assignee; and provided, further, that no Lender -------- shall be permitted to make an assignment of its rights and obligations hereunder to an Assignee unless the parent, a subsidiary or an affiliate of such Lender which is party to the U.S. Credit Agreement makes a concurrent and proportionate assignment of its rights and obligations thereunder to the proposed Assignee or the parent, a subsidiary or an affiliate of the proposed Assignee, such assignment to be effected in accordance with subsection 11.6(c) of the U.S. Credit Agreement. Upon such execution, delivery, acceptance and recording, from and after the effective date determined pursuant to such Assignment and Acceptance, (x) the Assignee thereunder shall be a party hereto and, to the extent provided in such Assignment and Acceptance, have the rights and obligations of a Lender hereunder with a Commitment as set forth therein, and (y) the assigning Lender thereunder shall be released from its obligations under this Agreement to the extent that such obligations shall have been expressly assumed by the Assignee pursuant to such Assignment and 132

Acceptance (and, in the case of an Assignment and Acceptance covering all or the remaining portion of an assigning Lender's rights and obligations under this Agreement, such assigning Lender shall cease to be a party hereto). Notwithstanding the foregoing, no Assignee, which as of the date of any assignment to it pursuant to this subsection 12.6(c) would be entitled to receive any greater payment under subsection 5.8 or 5.9, than the assigning Lender would have been entitled to receive as of such date under such subsections with respect to the rights assigned, shall be entitled to receive such payments unless the Borrower has consented in writing to the assignment. (d) The Administrative Agent shall maintain at its address referred to in subsection 12.2 a copy of each Assignment and Acceptance delivered to it and a register (the "Register") for the recordation of the names and addresses -------- of the Lenders and the Commitment of, and principal amount of the Loans owing to, each Lender from time to time. The entries in the Register shall be conclusive, in the absence of manifest error, and the Borrower, the Administrative Agent, the Collateral Agent and the Lenders may treat each Person whose name is recorded in the Register as the owner of the Loan recorded therein for all purposes of this Agreement. The Register shall be available for inspection by the Borrower, the Collateral Agent or any Lender at any reasonable time and from time to time upon reasonable prior notice. (e) Upon its receipt of an Assignment and Acceptance executed by an assigning Lender and an Assignee (and, in the case of an Assignee that is not then a Lender, or an Affiliate thereof, executed by the Borrower and the Administrative Agent), together with payment to the Administrative Agent of a registration and processing fee of C$1,500 (in the case of any assignment to a Lender, an Affiliate thereof) and C$3,500 (in the case of any other assignment), the Administrative Agent shall (i) promptly accept such Assignment and Acceptance and (ii) on the effective date determined pursuant thereto record the 133

information contained therein in the Register and give prompt notice of such acceptance and recordation to the Lenders and the Borrower. On or prior to such effective date, the assigning Lender shall surrender the outstanding Notes held by it all or a portion of which are being assigned, and the Borrower, at its own expense, shall execute and deliver to the Administrative Agent (in exchange for the outstanding Notes of the assigning Lender) a new Revolving Credit Note and/or Swing Line Note, as the case may be, to the order of such Assignee and representing the obligation of the Borrower to pay an amount equal to (i) in the case of a Revolving Credit Note, the lesser of (A) the amount of such Assignee's Commitment and (B) the aggregate principal amount of all Revolving Credit Loans made by such Assignee, and (ii) in the case of a Swing Line Note, the lesser of (A) the Swing Line Commitment and (B) the aggregate principal amount of all Swing Line Loans made by such Assignee, in each case with respect to the relevant Commitment after giving effect to such Assignment and Acceptance and, if the assigning Lender has retained a Commitment hereunder, a new Revolving Credit Note and/or Swing Line Note, as the case may be, to the order of the assigning Lender and representing the obligation of the Borrower to pay an amount equal to (i) in the case of a Revolving Credit Note, the lesser of (A) the amount of such Lender's Commitment and (B) the aggregate principal amount of all Revolving Credit Loans made by such Lender, and (ii) in the case of a Swing Line Note, the lesser of (A) the Swing Line Commitment and (B) the aggregate principal amount of all Swing Line Loans made by such Lender, in each case with respect to the relevant Commitment after giving effect to such Assignment and Acceptance. Such new Notes shall be dated the Closing Date and shall otherwise be in the form of the Note replaced thereby. The Notes surrendered by the assigning Lender shall be returned by the Administrative Agent to the Borrower marked "cancelled". (f) The Borrower authorizes each Lender to disclose to any Participant or Assignee (each, a "Transferee") and any prospective Transferee, ---------- subject to the 134

As you know, in connection with the sale of the assets of the Division, Westinghouse is assigning its interest in the lease of the Property to the undersigned, WESCO Distribution-Canada, Inc. In connection with the acquisition of the assets of the Division, we have arranged for financing from a group of banks to which The Bank of Nova Scotia is serving as Administrative Agent. These banks have agreed to make loans to us secured, among other things, by a first lien on any inventory that is now or in the future may be located at the Property and at other acquired properties and the Administrative Agent has asked that we notify you and have you agree to this letter and return it to us in the enclosed postage-paid envelope. By signing this letter you agree that any lien of any kind that you may have or obtain on our inventory shall be junior to the Administrative Agent's lien, and that prior to taking any action to enforce any lien, you will give the Administrative Agent at least ten (10) business days' prior notice of your intent to take action. If we should default to the banks, you agree that in all circumstances the Administrative Agent may have access to the Property for the purpose of removing or selling the inventory, provided that the Administrative Agent agrees to pay

you for any physical damage to the Property caused by the Administrative Agent in connection with any removal or sale. Because these loans are important for the future of our company and because the bank group and the Administrative Agent will be relying on this letter, we would greatly appreciate it if you would sign the enclosed copy of this letter and return it to me in the enclosed envelope. If you have any questions, please feel free to contact ___________________, at (____) ________. Thank you in advance for your cooperation. Sincerely, WESCO DISTRIBUTION-CANADA, INC.

the time in the possession of the Grantor to the Collateral Agent on demand, and it is agreed that the Collateral Agent shall have the right (subject to applicable law), with or without legal process and with or without previous notice or demand for performance, to exercise any and all rights afforded to a secured party under the UCC or other Applicable Law. Without limiting the generality of the foregoing, the Grantor agrees that the Collateral Agent shall have the right, subject to the mandatory requirements of current law, to sell or otherwise dispose of all or any part of the Collateral, at public or private sale or at any broker's board or on any securities exchange, for cash, upon credit or for future delivery as the Collateral Agent shall deem appropriate. The Collateral Agent shall be authorized at any such sale (if it deems it advisable to do so) to restrict the prospective bidders or purchasers to persons who will represent and agree that they are purchasing the Collateral for their own account for investment and not with a view to the distribution or sale thereof, and upon consummation of any such sale the Collateral Agent shall have the right to assign, transfer and deliver to the purchaser or purchasers thereof the Collateral so sold. Each such purchaser at any such sale shall hold the property sold absolutely, free from any claim or right on the part of the Grantor, and the Grantor hereby waives (to the extent permitted by law) all rights of redemption, stay and appraisal which the Grantor now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted. The Collateral Agent shall give the Grantor 10 days' written notice (which the Grantor agrees is reasonable notice within the meaning of Section 9- 504(3) of the UCC as in effect in the State of New York or its equivalent in other jurisdictions) of the Collateral Agent's intention to make any sale of Collateral. Such notice, in the case of a public sale, shall state the time and place for such sale and, in the case of a sale at a broker's board or on a securities exchange, shall state the board or exchange at which such sale is to be made and the day on which the 34

Collateral, or portion thereof, will first be offered for sale at such board or exchange. Any such public sale shall be held at such time or times within ordinary business hours and at such place or places as the Collateral Agent may fix and state in the notice (if any) of such sale. At any such sale, the Collateral, or portion thereof, to be sold may be sold in one lot as an entirety or in separate parcels, as the Collateral Agent may (in its sole and absolute discretion) determine. The Collateral Agent shall not be obligated to make any sale of any Collateral if it shall determine not to do so, regardless of the fact that notice of sale of such Collateral shall have been given. The Collateral Agent may, without notice or publication, adjourn any public or private sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for sale, and such sale may, without further notice, be made at the time and place to which the same was so adjourned. In case any sale of all or any part of the Collateral is made on credit or for future delivery, the Collateral so sold may be retained by the Collateral Agent until the sale price is paid by the purchaser or purchasers thereof, but the Collateral Agent shall not incur any liability in case any such purchaser or purchasers shall fail to take up and pay for the Collateral so sold and, in case of any such failure, such Collateral may be sold again upon like notice. At any public sale made pursuant to this Section, any Secured Party may bid for or purchase, free (to the extent permitted by law) from any right of redemption, stay, valuation or appraisal on the part of the Grantor (all said rights being also hereby waived and released to the extent permitted by law), the Collateral or any part thereof offered for sale and may make payment on account thereof by using any claim under any Loan Document then due and payable to such Secured Party from the Grantor as a credit against the purchase price, and such Secured Party may, upon compliance with the terms of sale, hold, retain and dispose of such property without further accountability to the Grantor therefor. For purposes hereof, a written agreement to purchase the Collateral or any portion thereof shall be treated as a sale thereof; the Collateral Agent shall be 35

free to carry out such sale pursuant to such agreement and the Grantor shall not be entitled to the return of the Collateral or any portion thereof subject thereto, notwithstanding the fact that after the Collateral Agent shall have entered into such an agreement all Events of Default shall have been remedied and the Obligations paid in full. As an alternative to exercising the power of sale herein conferred upon it, the Collateral Agent may proceed by a suit or suits at law or in equity to foreclose this Agreement and to sell the Collateral or any portion thereof pursuant to a judgment or decree of a court or courts having competent jurisdiction or pursuant to a proceeding by a court-appointed receiver. Section 6.2 Application of Proceeds. The Collateral Agent shall ----------------------- apply the proceeds of any collection or sale of the Collateral, as well as any Collateral consisting of cash and any amounts paid to the Collateral Agent pursuant to any Mortgage, as follows: FIRST, to the payment of all costs and expenses incurred by the Collateral Agent in connection with such collection or sale or otherwise in connection with this Agreement, any of the Mortgages or any of the Obligations, including all court costs and the reasonable fees and expenses of its agents and one legal counsel for it and the holders of the Notes (plus any necessary local counsel), the repayment of all advances made by the Collateral Agent hereunder or under any Mortgage on behalf of the Grantor and any other costs or expenses incurred in connection with the exercise of any right or remedy hereunder or under any Mortgage; SECOND, to the payment in full of the Obligations other than the payment of the Accreted Value of the Notes and other than all monetary obligations of the Grantor under the Guaranty Agreement (the amounts so 36

applied to be distributed among the Secured Parties pro rata in accordance with the amounts of such Obligations owed to them on the date of any such distribution); THIRD, to the payment in full of the Accreted Value of the Notes (the amounts so applied to be distributed among the Secured Parties pro rata in accordance with the Accreted Value of the Notes held by them on the date of any such distribution); FOURTH, to the payment in full of all monetary obligations of the Grantor under the Guaranty Agreement (the amounts so applied to be distributed among the Secured Parties pro rata in accordance with the amounts of such Obligations owed to them on the date of any such distribution); and FIFTH, to the Grantor or its successors, or to whomsoever may lawfully be entitled to receive the same. The Collateral Agent shall have absolute discretion as to the time of application of any such proceeds, moneys or balances in accordance with this Agreement; provided, however, that the Collateral Agent shall apply such -------- ------- proceeds, moneys or balances within six months of receipt thereof (such six months to be subject to extension during any period for which the Collateral Agent is not permitted by Applicable Law or this Agreement to apply such proceeds, moneys or balances). Upon any sale of the Collateral by the Collateral Agent (including pursuant to a power of sale granted by statute or under a judicial proceeding), the receipt of the Collateral Agent or of the officer making the sale shall be a sufficient discharge to the purchaser or purchasers of the Collateral so sold and such purchaser or purchasers shall not be obligated to see to the application of any part of the purchase money paid over to the Collateral Agent or such officer or be answerable in any way for the misapplication thereof. 37

The Collateral Agent shall have only those duties and responsibilities which are expressly specified in the Loan Documents and it may perform such duties by or through its agents or employees. The duties of the Collateral Agent shall be mechanical and administrative in nature; and the Collateral Agent shall not have by reason of any Loan Document a fiduciary relationship in respect of any Secured Party; and nothing in any of the Loan Documents, expressed or implied, is intended to or shall be so construed as to impose upon the Collateral Agent any obligations in respect of any of the Loan Documents except as expressly set forth therein. (b) The Collateral Agent shall not be responsible to any Secured Party for the execution, effectiveness, genuineness, validity, enforceability, collectability or sufficiency of any of the Loan Documents or for any Liens or Guaranties granted by, or purported to be granted by, any of the Loan Documents, or for any representations, warranties, recitals or statements made herein or therein or made in any written or oral statement or in any financial or other 38

statements, instruments, reports, certificates or any other documents in connection herewith or therewith furnished or made by the Collateral Agent to any Secured Party or by or on behalf of Buyer, Newco, the Grantor or the Canadian Buyer, to the Collateral Agent or any Secured Party, or be required to ascertain or inquire as to the performance or observance of any of the terms, conditions, provisions, covenants or agreements contained herein or therein or of the existence or possible existence of any Default or Event of Default. (c) Notwithstanding anything to the contrary in this Agreement, neither the Collateral Agent, nor any of its officers, directors, employees, agents, investigators, consultants, attorneys-in-fact or affiliates shall be liable to any Secured Party for any action taken or omitted under any of the Loan Documents or in connection herewith or therewith unless, but only to the extent, caused by its or their gross negligence or willful misconduct. If the Collateral Agent shall request instructions with respect to any act or action (including the failure to take an action) in connection with any of the Loan Documents, the Collateral Agent shall be entitled to refrain from such act or taking such action unless and until it shall have received instructions from the Required Mortgage Lenders. Without prejudice to the generality of the foregoing, (i) the Collateral Agent shall be entitled to rely, and shall be - fully protected in relying, upon any communication, instrument or document believed by it to be genuine and correct and to have been signed or sent by the proper person or persons, and shall be entitled to rely and shall be protected in relying on opinions and judgments of attorneys (who may be attorneys for the Grantor or its Affiliates), accountants, experts and other professional advisors selected by it; and (ii) no Secured Party shall have any right of action -- whatsoever against the Collateral Agent as a result of the Collateral Agent acting or (where so instructed) refraining from acting under any Loan Document in accordance with the instructions of the Required Mortgage Lenders. The Collateral Agent shall be entitled to refrain 39

from exercising any power, discretion or authority vested in it under the Loan Documents unless and until it has obtained the instructions of the Required Mortgage Lenders. (d) The agency hereby created shall in no way impair or affect any of the rights and powers of, or impose any duties or obligations upon, the Collateral Agent in its individual capacity as a Secured Party. With respect to any Notes or Canadian Notes that it holds, the Collateral Agent shall have the same rights and powers hereunder as any other Secured Party and may exercise the same as though it were not performing the duties and functions delegated to it hereunder. The Collateral Agent and its Affiliates may accept deposits from, lend money to and generally engage in any kind of banking, trust, financial advisory or any other business with the Grantor or any Affiliate of the Grantor as if it were not performing the duties specified herein, and may accept fees and other consideration from the Grantor or any Affiliate of the Grantor without having to account for the same to the Secured Parties. (e) Without limiting the foregoing, the Collateral Agent may deem and treat the holder of any Note or any Canadian Note as the owner thereof for all purposes. Any request, authority or consent of any Person who, at the time of making such request or giving such authority or consent, is the holder of any Note or Canadian Note shall be conclusive and binding on any subsequent holder, transferee or assignee of that Note or Canadian Note or of any Note or Canadian Note issued in exchange therefor. (f) The Collateral Agent shall be entitled to rely, and shall be fully protected in relying, on the Register and the copies of the "Register" (as defined in the Canadian Notes), in each case as provided to the Collateral Agent by the Grantor pursuant to Section 4.10, for purposes of determining the names and addresses of the holders of the Notes and the Canadian Notes. 40

Each Secured Party, by its --------------------- acquisition of any Note or Canadian Note, expressly acknowledges that neither the Collateral Agent, nor any of its officers, directors, employees, agents, attorneys-in-fact or affiliates have made any representations or warranties to it and that no act by the Collateral Agent hereinafter taken shall be deemed to constitute any representation or warranty by such Person.

direction of the Required Mortgage Lenders, if in the good faith determination of the Collateral Agent the interests of the Secured Parties would be adversely affected were such action to be delayed pending the obtaining of such consent or direction. In each circumstance where any consent of or direction from the Required Mortgage Lenders is required, the Collateral Agent shall send to the Secured Parties a notice setting forth a description in reasonable detail of the matter as to which consent or direction is requested and the Collateral Agent's proposed course of action with respect thereto. In the event the Collateral Agent shall not have received a response from any Secured Party within five Business Days after the giving of such notice (unless such notice is given by mail, in which case 10 Business Days after the giving of such notice), such Secured Party shall be deemed to have agreed to the course of action proposed by the Collateral Agent, provided that such notice states that a failure to respond shall have the consequences specified in this sentence.

GUARANTY The undersigned, CDW HOLDING CORPORATION, CDW ACQUISITION CORPORATION (to be renamed WESCO Distribution, Inc.) and CDW REALCO, INC. (the "Guarantors"), for valuable consideration, hereby each, jointly and severally, unconditionally and irrevocably guarantee, as primary obligor and not merely surety, (i) the due and punctual payment of the Principal Amount (plus all - accrued and unpaid interest thereon) of this Note, as the same shall become due and payable, whether at the date of maturity or by prepayment or acceleration or otherwise, (ii) the due and punctual payment of each other payment required to -- be made by Maker under this Note or any of the Mortgage Documents and (iii) the --- due and punctual performance by Maker of all other obligations of Maker, respectively, under this Note and the Mortgage Documents (all the foregoing obligations being collectively called the "Guaranteed Obligations"). This Guaranty is an absolute, unconditional present and continuing Guaranty of payment and not of collectibility, and in any case in which the Maker shall fail or be unable punctually to make any payment required to be made by or in respect of this Note, the Guarantors jointly and severally agree to pay the same to the holder of this Note forthwith upon demand. The obligations of each Guarantor under this Guaranty are general full recourse obligations of such Guarantor and may be fully enforced against such Guarantor. (a) Except as provided below in this subsection (a), all payments made to Payee by any Guarantor pursuant to this Guaranty shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any governmental authority, excluding (i) net income - taxes, franchise taxes, branch taxes or taxes on the overall capital or net worth of Payee imposed by any jurisdiction under the laws of which Payee is organized or

is located, or in which its principal executive office is located, or any nation within which such jurisdiction is located or any political subdivision thereof and (ii) any such taxes or other tax, levy, impost, duty, charge, fee, -- deduction or withholding imposed by reason of any connection between the jurisdiction imposing such tax and Payee, other than a connection arising solely from Payee having received payment under or enforced, this Guaranty. If any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or withholdings ("Non-Excluded Taxes") are required to be withheld from any ------------------ amounts payable to Payee hereunder, the amounts so payable to Payee shall be increased to the extent necessary to yield to Payee (after payment of all Non- Excluded Taxes, and all Non-Excluded Taxes on the amount of such increase), interest or any such other amounts payable hereunder at the rates or in the amounts specified in the Note on which this Guaranty is endorsed, provided, -------- however, that such Guarantor shall be entitled to deduct and withhold any Non- - ------- Excluded Taxes and shall not be required to increase any such amounts payable to Payee if Payee is not organized under the laws of Canada or a province thereof or is not a resident of Canada for purposes of the Income Tax Act (Canada), as amended from time to time. Whenever any Non-Excluded Taxes are payable by any Guarantor, as promptly as possible thereafter such Guarantor shall send to Payee a certified copy or an original official receipt received by such Guarantor showing payment thereof. If such Guarantor fails to pay any Non-Excluded Taxes when due to the appropriate taxing authority or fails to remit to Payee the required receipts or other required documentary evidence, such Guarantor shall indemnify Payee for any incremental taxes, interest or penalties that may become payable by Payee as a result of any such failure. The agreements in this subsection shall survive the payment of the Note on which this Guaranty is endorsed and all other amounts payable hereunder. Upon the request, and at the expense, of any such Guarantor, Payee shall reasonably afford such Guarantor the opportunity to contest, and reasonably cooperate with such 2

Guarantor in contesting, the imposition of any Non-Excluded Tax giving rise to such payment; provided that (i) Payee shall not be required to afford such -------- - Guarantor the opportunity to so contest unless such Guarantor shall have confirmed in writing to Payee its obligation to pay such amounts pursuant to this Guaranty and (ii) such Guarantor shall reimburse Payee for its reasonable -- attorneys' and accountants' fees and disbursements incurred in so cooperating with such Guarantor in contesting the imposition of such Non-Excluded Tax. (b) Each Guarantor waives presentment to, demand of payment from and protest to Maker of any of the Guaranteed Obligations, and also waives notice of acceptance of this Guaranty and notice of protest for nonpayment. The obligation of each Guarantor hereunder shall not be affected by (i) the failure - of any Person to assert any claim or demand or to enforce any right or remedy against Maker under the provisions of this Note or any Mortgage Document or otherwise; (ii) any rescission, waiver, amendment or modification of, or any -- release from any of the terms or provisions of, any Guaranty or any other agreement; (iii) the release of any security held by any Person for the --- Guaranteed Obligations or any of them; or (iv) the failure of any Person to -- exercise any right or remedy against any other guarantor of the Guaranteed Obligations. Each Guarantor further waives any right to require that any resort be had to any security held for payment of the Guaranteed Obligations or to any balance of any deposit account or credit on the books of any Person in favor of Maker or any other Person. (c) The obligations of each Guarantor shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense or setoff, counterclaim, recoupment or termination whatsoever by reason of the invalidity, illegality or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the fore- 3

going, the obligations of each Guarantor hereunder shall not be discharged or impaired or otherwise affected by the failure of any Person to assert any claim or demand or to enforce any remedy under this Note, any Mortgage Document, any Guaranty or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the Guaranteed Obligations, or by any other act or omission which may or might in any manner or to any extent vary the risk of the Guarantors or otherwise operate as a discharge of the Guarantors as a matter of law or equity (other than the payment in full of all the Guaranteed Obligations). Upon payment and performance in full of the Guaranteed Obligations, each Guarantor shall be subrogated to the rights of the holder of this Note in respect of any payment or other obligation with respect to which an amount has been payable by such Guarantor hereunder. This Guaranty shall survive and be in full force and effect so long as any Guaranteed Obligation is outstanding and has not been indefeasibly paid. (d) Paragraphs 10, 12, 14 and 15 and the first sentence of paragraph 13 of this Note shall apply to this Guaranty as if references therein to "this Note" were references to this Guaranty and references therein to "Maker" were references to the Guarantors. The definitions in paragraph 2 of this Note and the second sentence of paragraph 13 of this Note shall apply to this Guaranty. 4

(4) The amount of cash to be withdrawn (i) does not exceed the aggregate amount shown on the invoice or invoices accompanying the certificate delivered pursuant to Section 5.04(d)(1)(B) and (ii) when aggregated with all other amounts previously withdrawn pursuant to this Section with respect to such Mortgaged Property, does not exceed such Specified Loss Proceeds. (5) Either (i) the cash withdrawn is paid to the Grantor to reimburse the Grantor for amounts paid to the issuer of the invoice or invoices accompanying the certificate delivered pursuant to Section 5.04(d)(1)(B) that are marked "paid" or (ii) the Grantor directs that the cash withdrawn is to be paid to, or at the direction of, the issuer or issuers of any unpaid invoice or invoices. (e) Unless an Event of Default has occurred and is continuing, the Collateral Agent will withdraw cash from the Specified Loss Account and pay such cash at the direction of the Grantor on the date specified by the Grantor if the following conditions shall have been satisfied: (1) The Grantor shall have requested in writing that the Collateral Agent effect such withdrawal not less than 10 Business Days prior to the date on which such cash is to be withdrawn. Such request shall have specified the amount of cash to be withdrawn and specified the Mortgaged Property the replacement of which is to be effected with the cash to be withdrawn and shall have been accompanied by (A) a certificate, signed by the chief financial officer of Newco, to the effect that (x) no Event of Default has occurred and is continuing and (y) the proceeds of such withdrawal are to be used to finance the purchase by the Grantor of Replacement Property from a Person who is not an Affiliate of the Grantor and (B) a copy of a contract for the purchase of the Replacement Property. (2) On or prior to the date on which such cash is to be withdrawn, the Collateral Agent shall have received (A) a first mortgage securing the 22

Obligations, in registrable form and otherwise substantially in the form and substance of the Mortgages, of the Replacement Property, duly executed and delivered by the Grantor, (B) at the Collateral Agent's option (acting reasonably), either (i) a title opinion rendered by legal counsel, duly qualified in the jurisdiction in which the Replacement Property is located and satisfactory to the Collateral Agent (acting reasonably), confirming the fee simple interest of the Grantor in the Replacement Priority, the priority of the Collateral Agent's mortgage therein (in each case, subject only to standard exceptions and Permitted Encumbrances) and such other matters as the Collateral Agent may reasonably request or (ii) a title insurance policy, issued by a nationally recognized title insurance company satisfactory to the Collateral Agent (acting reasonably), insuring the Lien of the Collateral Agent's mortgage in the Replacement Property subject only to standard exceptions and Permitted Encumbrances, in an amount not less than the amount of the proposed withdrawal, and (C) such surveys, environmental audits and documents relating to the Permitted Encumbrances and compliance with Applicable Law and applicable Governmental Approvals, as reasonably requested by the Collateral Agent, as shall be reasonably necessary to satisfy the Collateral Agent that the mortgaging of the Replacement Property to secure the Obligations and the proposed withdrawal, taken together, would not materially and adversely affect the aggregate value of the Mortgaged Property and the Collateral or the rights and remedies of the Collateral Agent or any of the Secured Parties under the Loan Documents or the ability of the Collateral Agent or any of the Secured Parties to exercise the same. (3) On the date on which such cash is to be withdrawn, the Collateral Agent shall have received a certificate bringing down to date the certificate referred to in Section 5.04(e)(1)(A). (4) If the Replacement Property is being purchased in connection with the purchase by the Grantor, or any of its Affiliates, of any assets or services from the seller of the Replacement Property or any of its Affiliates, the Collateral Agent shall be reasonably satisfied that the amount of cash proposed to be withdrawn shall not be greater than the fair market value of the Replacement Property. If the Replacement Property is not being purchased in connection with the purchase by the Grantor, or any of its Affiliates, of any assets or services from the seller of the Replacement Property or any of its Affiliates, the Collateral Agent shall be reasonably satisfied that the amount of cash proposed to be withdrawn shall not be greater than the cash purchase price for the Replacement Property. 23

(5) The amount of cash to be withdrawn in respect of any Mortgaged Property (when aggregated with all other amounts previously withdrawn pursuant to this Section 5.04 with respect to such Mortgaged Property) does not exceed the Specified Loss Proceeds received in respect of such Mortgaged Property. (6) The Grantor directs that the cash withdrawn is to be paid to, or at the direction of, the seller of the Replacement Property. (f) If Specified Loss Proceeds with respect to a Mortgaged Property have been withdrawn from the Specified Loss Account pursuant to Section 5.04(d), upon completion of the repairs to such Mortgaged Property the Grantor shall direct the Collateral Agent pursuant to Section 5.04(c) to apply any balance of such Specified Loss Proceeds with respect to such Mortgaged Property remaining in the Specified Loss Account to the prepayment of the Notes. If the Grantor has notified the Collateral Agent in accordance with the Mortgage that Specified Loss Proceeds with respect to a Mortgaged Property are to be used to finance the purchase of Replacement Property pursuant to Section 5.04(e), the Grantor may at any time and from time to time direct the Collateral Agent pursuant to Section 5.04(c) to apply any portion of such Specified Loss Proceeds with respect to such Mortgaged Property to the prepayment of the Notes. (g) If an Event of Default has occurred and is continuing, the Collateral Agent may, in its sole discretion, apply all amounts on deposit in the Specified Loss Account to satisfy in accordance with Section 6.02 any Obligations then due and payable. Section 5.05 Investment. Unless an Event of Default has occurred and ---------- is continuing, the Collateral Agent will accept directions from the Grantor as to the investment of any funds in any Cash Collateral Account in Permitted Investments; provided, however, that (i) the Collateral Agent shall not be -------- ------- required to make any investment that, in its sole judgment, would require or cause the Collateral Agent to be, or would result in, any violation of Applicable Law or any Governmental Approval, (ii) the Collateral Agent shall be authorized to sell any investment held for the account of any Cash Collateral Account to the extent cash is needed in such Cash Collateral Account to make a withdrawal of cash from such Cash Collateral Account (and shall not be liable for any loss resulting from any such sale) and (iii) the Collateral Agent shall not be required to make any investment unless the Collateral Agent is able to perfect the Security Interest in such investment. The Grantor will indemnify the Collateral Agent for any losses resulting from such investments pursuant to this Section. Except as expressly set forth in this Section, the Collateral Agent shall not be obligated to invest any amounts on deposit in any Cash Collateral Account, nor shall 24

any Cash Collateral Account pay interest. The Collateral Agent shall, upon reasonable request from the Grantor from time to time, provide the Grantor with a report as to the Collateral Agent's holdings of Permitted Investments. ARTICLE VI. REMEDIES Section 6.01 Remedies upon Default. (a) Upon the occurrence and --------------------- during the continuance of an Event of Default, the Grantor will deliver each item of Collateral at the time in the possession of the Grantor to the Collateral Agent on demand, and it is agreed that the Collateral Agent shall have the right (subject to applicable law), with or without legal process and with or without previous notice or demand for performance, to exercise, in addition to all other rights granted to the Collateral Agent in this Agreement, any and all rights afforded to a secured party under the PPSA or other Applicable Law. Without limiting the generality of the foregoing, the Collateral Agent (and, in the case of Section 6.01(vi), any other Secured Party) may at any time or from time to time upon the occurrence and during the continuance of an Event of Default take any one or more of the following actions: (i) enter into possession of the Collateral; (ii) commence proceedings in any court of competent jurisdiction for sale or foreclosure of all or any part of the Collateral; (iii) file proofs of claim and any other documents to establish its claims in any proceeding relative to the Grantor; (iv) collect, receive, appropriate and realize upon the Collateral, and/or sell, give one or more options to purchase, or otherwise dispose of and deliver all or any part of the Collateral (or contract to do any of the foregoing), at public or private sale or sales, at any broker's board or on any securities exchange or elsewhere upon such terms and conditions as the Collateral Agent may deem advisable and at such prices as it may deem best, for cash or on credit or future delivery without assumption of any credit risk; (v) enforce collection of any of the Collateral by suit or otherwise, and surrender, release or exchange all or any part of any property in addition to the Collateral securing any of the Obligations, or compromise or extend or renew for any period (whether or not longer than the original period) any obligations of any nature of any Person with respect to any such property; and/or 25

(vi) to the extent permitted by applicable law, purchase any or all of the Collateral, whether in connection with a sale made under the power of sale herein contained or pursuant to judicial proceedings or otherwise. (b) Without limiting the generality of the foregoing and, in particular, of Sections 6.01(l)(iv) and 6.01(l)(vi), the Collateral Agent shall be authorized at any offer or sale of any of the Collateral (if it deems it advisable to do so) to restrict the prospective bidders or purchasers to Persons who will represent and agree that they are purchasing the Collateral for their own account for investment and not with a view to the distribution or sale thereof, and upon consummation of any such sale the Collateral Agent shall have the right to assign, transfer and deliver to the purchaser or purchasers thereof the Collateral so sold. Each such purchaser at any such public or private sale shall hold the property sold absolutely, free from any claim or right on the part of the Grantor, and the Grantor hereby waives (to the extent permitted by law) all rights or equity of redemption, stay and appraisal which the Grantor now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted. At any such public or private sale, the Collateral, or portion thereof, to be sold may be sold in one lot as an entirety or in separate parcels, as the Collateral Agent may (in its sole and absolute discretion) determine. The Collateral Agent shall not be obligated to make any sale of any Collateral if it shall determine not to do so, regardless of the fact that notice of sale of such Collateral shall have been given. The Collateral Agent may, without notice or publication, adjourn any public or private sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for sale, and such sale may, without further notice, be made at the time and place to which the same was so adjourned. In case any sale of all or any part of the Collateral is made on credit or for future delivery, the Collateral so sold may be retained by the Collateral Agent until the sale price is paid by the purchaser or purchasers thereof, but the Collateral Agent shall not incur any liability in case any such purchaser or purchasers shall fail to take up and pay for the Collateral so sold and, in case of any such failure, such Collateral may be sold again upon like notice. At any sale made pursuant to this Section 6.01 to any Secured Party, the Collateral or any part thereof purchased by any such Secured Party shall be free (to the extent permitted by law) from any right or equity of redemption, stay, valuation or appraisal on the part of the Grantor (all said rights being also hereby waived and released to the extent permitted by law). To the extent permitted by law, such Secured Party may make payment on account of such sale by using any claim under any Loan Document then due and payable to such Secured Party from the Grantor as a credit against the purchase price, and such Secured Party may, upon compliance with the terms of sale, hold, retain and dispose of such property without further accountability to the Grantor therefor. For purposes hereof, a written agreement to purchase the Collateral or any portion thereof shall be treated as a sale thereof; the Collateral Agent shall be free to carry out such sale pursuant to such agreement and the Grantor shall not be entitled to the return of the Collateral or any 26

portion thereof subject thereto, notwithstanding the fact that after the Collateral Agent shall have entered into such an agreement all Events of Default shall have been remedied and the Obligations paid in full. (c) The Collateral Agent may take any or all of the foregoing actions without demand of performance or other demand, presentment, protest, advertisement or notice of any kind (except as required by law) to or upon the Grantor or any other Person, and the Grantor hereby waives each such demand, presentment, protest, advertisement and notice to the extent permitted by applicable law. (d) To the extent permitted by applicable law, the Grantor waives all claims, damages and demands it may acquire against the Collateral Agent or any other Secured Party arising out of the exercise by the Collateral Agent of any rights hereunder. The Grantor will remain liable for any deficiency if the proceeds from any proceeding or of any collection, receipt, appropriation, realization, sale, other disposition or delivery of the Collateral are insufficient to pay and satisfy the Obligations. Section 6.02 Application of Proceeds. The Collateral Agent shall ----------------------- apply the proceeds from any proceeding or of any collection, receipt, appropriation, realization, sale, other disposition or delivery of any of the Collateral, as well as any Collateral consisting of cash and any amounts paid to the Collateral Agent pursuant to any Mortgage, as follows: FIRST, to the payment of all costs and expenses incurred by the Collateral Agent in connection with such collection or sale or otherwise in connection with this Agreement, any of the Mortgages or any of the Obligations or incidental to the care or safekeeping of any of the Collateral, including all court costs and the reasonable fees and expenses of its agents, experts and one legal counsel on a solicitor and his own client basis for it and the holders of the Notes (plus any necessary local counsel), the repayment of all advances made by the Collateral Agent hereunder or under any Mortgage on behalf of the Grantor and any other costs or expenses incurred in connection with the exercise of any right or remedy hereunder or under any Mortgage; SECOND, to the payment in full of the Obligations in such order as the Collateral Agent may elect (the amounts so applied to be distributed among the Secured Parties pro rata in accordance with the amounts of such Obligations owed to them on the date of any such distribution); and 27

THIRD, after payment by the Collateral Agent of any other amount required by applicable law, to the Grantor or its successors, or to whomsoever may lawfully be entitled to receive the same. The Collateral Agent shall have absolute discretion as to the time of application of any such proceeds, moneys or balances in accordance with this Agreement; provided, however, that the Collateral Agent shall apply such -------- ------- proceeds, moneys or balances within 6 months of receipt thereof (such 6 months to be subject to extension during any period for which the Collateral Agent is not permitted by Applicable Law or this Agreement to apply such proceeds, moneys or balances). Upon any sale of the Collateral by the Collateral Agent (including pursuant to a power of sale granted by statute or under a judicial proceeding), the receipt of the Collateral Agent or of the officer making the sale shall be a sufficient discharge to the purchaser or purchasers of the Collateral so sold and such purchaser or purchasers shall not be obligated to see to the application of any part of the purchase money paid over to the Collateral Agent or such officer or be answerable in any way for the misapplication thereof. ARTICLE VII. RIGHTS AND DUTIES OF COLLATERAL AGENT SECTION 7.01. Delegation of Duties. The Collateral Agent may execute -------------------- any of its duties under any Loan Document by or through agents or attorneys-in- fact and shall be entitled to advice of counsel or other advisors concerning all matters pertaining to its duties and rights hereunder. The Collateral Agent shall not be responsible for the negligence or misconduct of any agents or attorneys-in-fact selected by it with reasonable care except to the extent otherwise expressly required by Section 7.02 or 8.03. SECTION 7.02. Powers; General Immunity. (a) Each Secured Party, by ------------------------ its acquisition of any Note, irrevocably authorizes the Collateral Agent to take such action on such Secured Party's behalf and to exercise such powers under the Loan Documents as are specifically delegated to it by the terms thereof, together with such powers as are reasonably incidental thereto. The Collateral Agent shall have only those duties and responsibilities which are expressly specified in the Loan Documents and it may perform such duties by or through its agents or employees. The duties of the Collateral Agent shall be mechanical and administrative in nature; and the Collateral Agent shall not have by reason of any Loan Document a fiduciary relationship in respect of any Secured Party; and nothing in any of the Loan Documents, expressed or implied, is intended to or shall be so construed as to impose upon the Collateral Agent any obligations in respect of any of the Loan Documents except as expressly set forth therein. 28

(b) The Collateral Agent shall not be responsible to any Secured Party for the execution, effectiveness, genuineness, validity, enforceability, collectability or sufficiency of any of the Loan Documents or for any Liens or Guaranties granted by, or purported to be granted by, any of the Loan Documents, or for any representations, warranties, recitals or statements made herein or therein or made in any written or oral statement or in any financial or other statements, instruments, reports, certificates or any other documents in connection herewith or therewith furnished or made by the Collateral Agent to any Secured Party or by or on behalf of Buyer, Newco, Realco or the Grantor, to the Collateral Agent or any Secured Party, or be required to ascertain or inquire as to the performance or observance of any of the terms, conditions, provisions, covenants or agreements contained herein or therein or of the existence or possible existence of any Default or Event of Default. (c) Notwithstanding anything to the contrary in this Agreement, neither the Collateral Agent, nor any of its officers, directors, employees, agents, investigators, consultants, attorneys-in-fact or Affiliates shall be liable to any Secured Party for any action taken or omitted under any of the Loan Documents or in connection herewith or therewith unless, but only to the extent, caused by its or their gross negligence or willful misconduct. If the Collateral Agent shall request instructions with respect to any act or action (including the failure to take an action) in connection with any of the Loan Documents, the Collateral Agent shall be entitled to refrain from such act or taking such action unless and until it shall have received instructions from the Required Mortgage Lenders. Without prejudice to the generality of the foregoing, (i) the Collateral Agent shall be entitled to rely, and shall be fully protected in relying, upon any communication, instrument or document believed by it to be genuine and correct and to have been signed or sent by the proper person or persons, and shall be entitled to rely and shall be protected in relying on opinions and judgments of attorneys (who may be attorneys for the Grantor or its Affiliates), accountants, experts and other professional advisors selected by it; and (ii) no Secured Party shall have any right of action whatsoever against the Collateral Agent as a result of the Collateral Agent acting or (where so instructed) refraining from acting under any Loan Document in accordance with the instructions of the Required Mortgage Lenders. The Collateral Agent shall be entitled to refrain from exercising any power, discretion or authority vested in it under the Loan Documents unless and until it has obtained the instructions of Required Mortgage Lenders. (d) The agency hereby created shall in no way impair or affect any of the rights and powers of, or impose any duties or obligations upon, the Collateral Agent in its individual capacity as a Secured Party. With respect to any Notes that it holds, the Collateral Agent shall have the same rights and powers hereunder as any other Secured Party and may exercise the same as though it were not performing the duties and functions delegated to it hereunder. The Collateral Agent and its Affiliates 29

may accept deposits from, lend money to and generally engage in any kind of banking, trust, financial advisory or any other business with the Grantor or any Affiliate of the Grantor as if it were not performing the duties specified herein, and may accept fees and other consideration from the Grantor or any Affiliate of the Grantor without having to account for the same to the Secured Parties. (e) Without limiting the foregoing, the Collateral Agent may deem and treat the holder of any Note as the owner thereof for all purposes. Any request, authority or consent of any Person who, at the time of making such request or giving such authority or consent, is the holder of any Note shall be conclusive and binding on any subsequent holder, transferee or assignee of that Note or of any Note issued in exchange therefor. (f) The Collateral Agent shall be entitled to rely, and shall be fully protected in relying, on the Register and the copies of the Register, in each case as provided to the Collateral Agent by the Grantor pursuant to Section 4.06, for purposes of determining the names and addresses of the holders of the Notes. Section 7.03 Non-Reliance on Agent. Each Secured Party, by its --------------------- acquisition of any Note, expressly acknowledges that neither the Collateral Agent, nor any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates have made any representations or warranties to it and that no act by the Collateral Agent hereinafter taken shall be deemed to constitute any representation or warranty by such Person. The Collateral Agent shall not have any duty or responsibility either initially or on a continuing basis to make any such investigation or any such appraisal on behalf of the Secured Parties or to provide any Secured Party with any credit or other information with respect thereto, and the Collateral Agent shall not have any responsibility with respect to the accuracy of or the completeness of any information provided to the Secured Parties. Section 7.04 Determinations Pursuant to Loan Documents. In each ----------------------------------------- circumstance where, under any provision of any Loan Document, the Collateral Agent shall have the right to grant or withhold any consent, exercise any remedy, make any determination or direct any action under such Loan Document, the Collateral Agent shall act in respect of such consent, exercise of remedies, determination or action, as the case may be, only with the consent of and at the direction of the Required Mortgage Lenders; provided, however, that (i) no such -------- ------- consent of the Required Mortgage Lenders shall be required with respect to any consent, determination or other matter that is, in the Collateral Agent's reasonable judgment, ministerial or administrative in nature or provided for in such Loan Document, (ii) the Collateral Agent is hereby authorized on behalf of all of the Secured Parties, without the necessity of any further consent from any Secured Party, from time to time prior to an Event of Default, to 30

release the security interests and Liens imposed by the Mortgage Documents in connection with any dispositions permitted by the terms of the Mortgage Documents or as may be required by Applicable Law and (iii) the Collateral Agent may in its discretion take such action as it deems necessary, without the consent or direction of the Required Mortgage Lenders, if in the good faith determination of the Collateral Agent the interests of the Secured Parties would be adversely affected were such action to be delayed pending the obtaining of such consent or direction. In each circumstance where any consent of or direction from the Required Mortgage Lenders is required, the Collateral Agent shall send to the Secured Parties a notice setting forth a description in reasonable detail of the matter as to which consent or direction is requested and the Collateral Agent's proposed course of action with respect thereto. In the event the Collateral Agent shall not have received a response from any Secured Party within five Business Days after the giving of such notice (unless such notice is given by mail, in which case 10 Business Days after the giving of such notice), such Secured Party shall be deemed to have agreed to the course of action proposed by the Collateral Agent, provided that such notice states that a failure to respond shall have the consequences specified in this sentence. Section 7.05 Resignation of the Collateral Agent. The Collateral ----------------------------------- Agent may at any time, by giving 30 days' prior written notice to the Grantor, resign and be discharged from the responsibilities hereby created, such resignation to become effective upon the earlier of (i) the acceptance of the appointment of a successor pursuant to the next sentence of this Section or (ii) the appointment of a successor by the Required Mortgage Lenders and the acceptance of such appointment by such successor. If no successor shall be appointed and approved pursuant to clause (ii) above within 30 days after the date of any such resignation, the Collateral Agent may apply to any court of competent jurisdiction to appoint a successor to act until a successor shall have been appointed by the Required Mortgage Lenders as above provided or may, on behalf of the Secured Parties, appoint a successor Collateral Agent. Any successor Collateral Agent shall be (A) a Canadian chartered bank or any loan or trust company organized under the laws of Canada or any province thereof with an office in Toronto, Ontario, having a combined capital, surplus and undivided profits (less any undivided losses), as of its last annual audited financial statements, not less than C$250,000,000 and being authorized to perform the functions of the Collateral Agent hereunder (who, if appointed after the fourth anniversary of the Closing Date, shall be entitled to receive reasonable fees from the Grantor for its services as Collateral Agent) or (B) the holder of at least a majority of the aggregate Principal Amount of the Notes then outstanding plus all accrued interest thereon from the immediately preceding Interest Date. ARTICLE VII MISCELLANEOUS 31

Section 8.01 Security Interest Absolute; Release of Security ----------------------------------------------- Interest. (a) All rights of the Collateral Agent hereunder, the Security Interest and all obligations of the Grantor hereunder shall be absolute and unconditional irrespective of (a) any lack of validity or enforceability of the Notes (or any Guaranty endorsed thereon), any Mortgage, any agreement with respect to any of the Obligations or any other agreement or instrument relating to any of the foregoing, (b) any change in the time, manner or place of payment of, or in any other term of, all or any of the Obligations, or any other amendment or waiver of or any consent to any departure from the Notes (or any Guaranty endorsed thereon), any Mortgage or any other agreement or instrument, (c) any exchange, release or non-perfection of any Lien on other collateral, or any release or amendment or waiver of or consent under or departure from any guarantee, securing or guaranteeing all or any of the Obligations, or (d) any other circumstance which might otherwise constitute a defense available to, or a discharge of, the Grantor in respect of the Obligations or this Agreement, except the payment in full of the Obligations and except for any matter approved in writing by, subject to paragraph 14 of the Notes, the Required Mortgage Lenders and the Collateral Agent. (b) The consent or approval of any Secured Party shall not be required for the release of any Collateral by the Collateral Agent to the Grantor in accordance with the express provisions of this Agreement. Section 8.02 Successors. Whenever in this Agreement any of the ---------- parties hereto is referred to, such reference shall be deemed to include the successors of such party (including, in the case of the Collateral Agent, any successor Collateral Agent); and all covenants, promises and agreements by or on behalf of the Grantor or the Collateral Agent that are contained in this Agreement shall bind and inure to the benefit of their respective successors (including, in the case of the Collateral Agent, any successor Collateral Agent). Section 8.03 Collateral Agent Appointed Attorney-in-Fact. (a) The ------------------------------------------- Grantor hereby appoints the Collateral Agent the attorney-in-fact of the Grantor, with power of substitution and in the Grantor's name or otherwise, for the purpose of carrying out the provisions of this Agreement and taking any action and executing any instrument which the Collateral Agent may reasonably deem necessary or advisable to accomplish the purposes hereof, including, upon the occurrence and during the continuance of an Event of Default, the power to (a) receive, endorse, assign and/or deliver any and all notes, acceptances, checks, drafts, money orders or other evidences of payment relating to the Collateral or any part thereof; (b) demand, collect, receive payment of, give receipt for and give discharges and releases of all or any of the Collateral; (c) commence and prosecute any and all suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect or otherwise realize on all 32

or any of the Collateral or to enforce any rights in respect of any Collateral; (d) settle, compromise, compound, adjust or defend any actions, suits or proceedings relating to all or any of the Collateral; and (e) use, sell, assign, transfer, pledge, make any agreement with respect to or otherwise deal with all or any of the Collateral, and to do all other acts and things necessary to carry out the purposes of this Agreement, as fully and completely as though the Collateral Agent were the absolute owner of the Collateral for all purposes; provided, however, that nothing contained in this Section or in this Agreement - -------- ------- shall be construed as requiring or obligating the Collateral Agent to make any commitment or to make any inquiry as to the nature or sufficiency of any payment received by the Collateral Agent, or to present or file any claim or notice, or to take any action with respect to the Collateral or any part thereof or the moneys due or to become due in respect thereof or any property covered thereby, and no action taken or omitted to be taken by the Collateral Agent with respect to the Collateral or any part thereof shall give rise to any defense, counterclaim or offset in favor of the Grantor or to any claim or action against the Collateral Agent, other than any such matter to the extent arising out of the gross negligence or willful misconduct of the Collateral Agent. It is understood and agreed that the appointment of the Collateral Agent as the agent and attorney-in-fact of the Grantor for the purposes set forth above is coupled with an interest and is irrevocable. The provisions of this Section shall in no event relieve the Grantor of any of its obligations hereunder or under any Mortgage with respect to the Collateral or any part thereof or impose any obligation on the Collateral Agent or any Secured Party to proceed in any particular manner with respect to the Collateral or any part thereof, or in any way limit the exercise by the Collateral Agent or any Secured Party of any other or further right which it may have on the date of this Agreement or hereafter, whether hereunder, by law or otherwise; provided, however, that the Collateral -------- ------- Agent's sole duty with respect to the custody, safekeeping and physical preservation of the Collateral in its possession or under its control shall be to use reasonable care in the custody and preservation of such Collateral. The Grantor agrees that the Collateral Agent shall be deemed to have used reasonable care in the custody and preservation of the Collateral if the Collateral Agent deals with such Collateral in the same manner as the Collateral Agent deals with similar property for its own account and, to the extent permitted by applicable law, the Collateral Agent need not take any steps to preserve rights against any other Person (including prior parties). (b) The Grantor also authorizes the Collateral Agent, at any time and from time to time, upon the occurrence and during the continuance of an Event of Default, to execute any endorsements, assignments or other instruments of conveyance or transfer with respect to the Collateral in connection with any sale provided for in Section 6.01 hereof. Section 8.04 Collateral Agent's Expenses; Indemnification. (a) The -------------------------------------------- Grantor will pay upon demand to the Collateral Agent the amount of any and all 33

reasonable expenses, including the reasonable fees and expenses of one counsel on a solicitor and his own client basis for it and the holders of the Notes (plus any necessary local counsel), of any experts or agents and of any financial institution with which any Cash Collateral Account is maintained, which the Collateral Agent may incur in connection with (i) the administration of the Mortgage Documents, (ii) the custody, preservation or investment of, or the sale of, collection from or other realization upon any of the Collateral, (iii) the exercise, enforcement or protection of any of the rights of the Collateral Agent (hereunder, under any Mortgage or otherwise) or (iv) the failure of the Grantor to perform or observe any of the provisions hereof, other than any such expenses to the extent arising out of the gross negligence or willful misconduct of the Collateral Agent. If the Grantor fails to perform or observe any of the provisions hereof, then the Collateral Agent shall be entitled, but shall have no obligation, to perform or observe or otherwise cause the performance or observance of any of the provisions hereof. (b) The Grantor will indemnify the Collateral Agent against, and hold it harmless from, any and all losses, claims, damages, liabilities and related expenses, including reasonable counsel fees and expenses on a solicitor and his own client basis, incurred by or asserted against it arising out of, in any way connected with, or as a result of, the execution, delivery or performance of any Mortgage Document, or any exercise of remedies thereunder, or any claim, litigation, investigation or proceeding relating hereto or to the Collateral or any Mortgage or Mortgaged Property, whether or not a party thereto, other than, and only to the extent, caused by the gross negligence or willful misconduct of the Collateral Agent. (c) Any such amounts payable as provided hereunder shall be additional Obligations. The provisions of this Section shall remain operative and in full force and effect regardless of the termination of this Agreement, the consummation of the transactions contemplated hereby, the invalidity or unenforceability of any term or provision of this Agreement, any Note or any Mortgage, or any investigation made by or on behalf of the Collateral Agent. All amounts due under this Section shall be payable on written demand therefor. Section 8.05 Waivers, Amendment. (a) No failure or delay of the ------------------ Collateral Agent in exercising any power or right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Collateral Agent hereunder are cumulative, may be exercised singly or concurrently and in any order, and are not exclusive of any rights or remedies which it would otherwise have. No waiver of any provisions of this Agreement or consent to any departure by the Grantor therefrom shall in any event be effective unless 34

the same shall be permitted by Section 8.05(b), and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice or demand on the Grantor in any case shall entitle the Grantor to any other or further notice or demand in similar or other circumstances. (b) Neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Collateral Agent and the Grantor with respect to which such waiver, amendment or modification is to apply, subject to any consent required in accordance with paragraph 14 of the Notes. Section 8.06 Termination. This Agreement (including the ----------- representations and warranties herein) and the Security Interest shall terminate when and only when all the Obligations have been paid in full. Upon such termination, the Collateral Agent shall forthwith assign, transfer and deliver any Collateral in the possession or under the control of the Collateral Agent (including any Collateral in any Cash Collateral Account) to or on order of the Grantor and, at the Grantor's expense, execute and deliver to the Grantor such documents as the Grantor shall reasonably request to evidence such termination. Any execution and delivery of such documents shall be without recourse to or warranty by the Collateral Agent. Section 8.07 Severability. If any provision of this Agreement is ------------ inoperative or unenforceable for any reason, such circumstances shall not have the effect of rendering the provision in question inoperative or unenforceable in any other case or circumstance, or of rendering any other provision or provisions herein contained invalid, inoperative or unenforceable to any extent whatsoever. The invalidity of any one or more phrases, sentences, clauses, Sections or subsections of this Agreement shall not affect the remaining portions of this Agreement. Section 8.08 Notices.

in writing by holders holding at least a majority (by number of shares) of the Registrable Securities as to which registration has been requested pursuant to this Section 3.1.

Registrable Securities proposing to sell their securities in such registration and (if the Company proposes to sell securities for its own account in such offering) the Company shall share pro rata in the number of securities being offered (as determined by the holders holding a majority (by number of shares) of the Registrable Securities for which registration is being requested in consultation with the managing underwriters or investment banker, as the case may be) and registered for their account, such sharing to be based on the number of Registrable Securities as to which registration was requested by such holders and the number of securities that the Company proposed to sell for its own account in such offering, respectively, provided that, in the case of a -------- registration requested pursuant to Section 3.1(b), all Registrable Securities that the Person making such request under Section 3.1(b) wishes to include in such registration shall be included in such registration (at the time such registration becomes effective) before any other securities are included in such registration, unless such Person otherwise consents in writing. 3.2.

aforesaid) of the Registrable Securities so to be registered, provided that: -------- (a) if such registration shall be in connection with the Initial Public Offering, the Company shall not include any Registrable Securities in such proposed registration if the Company's Board of Directors shall have determined, after consultation with the managing underwriters for such offering, that it is not in the best interests of the Company to include any Registrable Securities in such registration, provided that, if the -------- Company's Board of Directors makes such a determination, the Company shall not include in such registration any securities not being sold for the account of the Company; (b) if, at any time after giving written notice of its intention to register any securities and prior to the effective date of the registration statement filed in connection with such registration, the Company shall determine for any reason not to register such securities, the Company may, at its election, give written notice of such determination to each holder of Registrable Securities that was previously notified of such registration and, thereupon, shall not register any Registrable Securities in connection with such registration (but shall nevertheless pay the Registration Expenses in connection therewith), without prejudice, however, to the rights of any holder or holders of Registrable Securities to request that a registration be effected under Section 3.1; and (c) if the Company shall be advised in writing by the managing underwriters (or, in connection with an offering which is not underwritten, by an investment banker) that in their or its opinion the number of securities requested to be included in such registration (whether by the Company, pursuant to this Section 3.2 or pursuant to any other rights granted by the Company to a holder or holders of its securities to 15

request or demand such registration or inclusion of any such securities in any such registration) exceeds the number of such securities which can be sold in such offering, (i) the Company shall include in such registration the number (if any) of Registrable Securities so requested to be included which in the opinion of such underwriters or investment banker, as the case may be, can be sold and shall not include in such registration any securities (other than securities being sold by the Company, which shall have priority in being included in such registration) so requested to be included other than Registrable Securities unless all Registrable Securities requested to be so included are included therein, and (ii) if in the opinion of such underwriters or investment banker, as the case may be, some but not all of the Registrable Securities may be so included, all holders of Registrable Securities requested to be included therein shall share pro rata in the number of shares of Registrable Securities included in such public offering on the basis of the number of Registrable Securities requested to be included therein by such holders, provided that, in the case of a registration -------- initially requested or demanded by a holder or holders of securities other than Registrable Securities, the holders of the Registrable Securities requested to be included therein and the holders of such other securities shall share pro rata (based on the number of shares if the requested or demanded registration is to cover only Common Stock and, if not, based on the proposed offering price of the total number of securities included in such public offering requested to be included therein), 16

and the Company shall so provide in any registration agreement hereinafter entered into with respect to any of its securities. The Company will pay all Registration Expenses in connection with each registration of Registrable Securities requested pursuant to this Section 3.2. No registration effected under this Section 3.2 shall relieve the Company from its obligation to effect registrations upon request under Section 3.1. 3.3. Registration Procedures.

By acquisition of Registrable Securities, each holder of such Registrable Securities shall be deemed to have agreed that upon receipt of any notice from the Company pursuant to Section 3.3(g), such holder will promptly discontinue such holder's disposition of Registrable Securities pursuant to the registration statement covering such Registrable Securities until such holder shall have received, in the case of clause (i) of Section 3.3(g), notice from the Company that such registration statement has been amended, as contemplated by Section 3.3(g), and, in the case of clause (ii) of Section 3.3(g), copies of the supplemented or amended prospectus contemplated by Section 3.3(g). If so directed by the Company, each holder of Registrable Securities will deliver to the Company (at the Company's expense) all copies, other than permanent file copies, in such holder's possession of the prospectus covering such Registrable Securities at the time of receipt of such notice. In the event that the Company shall give any such notice, the period mentioned in Section 3.3(b) shall be extended by the number of days during the period from and including the date of the giving of such notice to and including the date when each seller of any Registrable Securities covered by such registration statement shall have received the copies of the supplemented or amended prospectus contemplated by Section 3.3(g). 22

Although shares of Class A Common Stock issuable upon the exercise of options and shares of Class B Common Stock are included in the definition of Registrable Securities, the Company shall, in respect of any such Registrable Securities requested to be registered pursuant hereto, be required to include in any registration statement only shares of Class A Common Stock issuable upon conversion of or pursuant to such Registrable Securities and only if the Company has received assurances, reasonably satisfactory to it, in the case of shares issuable upon exercise of options, that such options will be exercised and in the case of Class B Common Stock that such Registrable Securities will be converted into shares of Class A Common Stock, in each case, promptly after such registration statement has become effective or the sale to an underwriter has been consummated so that only Class A Common Stock shall be distributed to the public under such registration statement. 3.4. Underwritten Offerings. The provisions of this Section 3.4 do ---------------------- not establish additional registration rights but instead set forth procedures applicable, in addition to those set forth in Sections 3.1 through 3.3, to any registration which is an underwritten offering. (a) Underwritten Offerings Exclusive. Whenever a registration -------------------------------- requested pursuant to Section 3.1 is for an underwritten offering, only securities which are to be distributed by the underwriters may be included in the registration. (b) Underwriting Agreement. If requested by the underwriters for any ---------------------- underwritten offering by holders of Registrable Securities pursuant to a registration requested under Section 3.1, the Company shall enter into an underwriting agreement with such underwriters for such offering, such agreement to be reasonably satisfactory in substance and form to the holders of a majority (by number of shares) of the Registrable Securities to be covered by such registration and to the underwriters and to contain such representations and warranties by the Company and such other 23

terms and provisions as are customarily contained in agreements of this type, including, but not limited to, indemnities to the effect and to the extent provided in Section 3.7, provisions for the delivery of officers' certificates, opinions of counsel and accountants' "comfort" letters and hold-back arrangements. The holders of Registrable Securities to be distributed by such underwriters shall be parties to such underwriting agreement and may, at their option, require that any or all of the representations and warranties by, and the agreements on the part of, the Company to and for the benefit of such underwriters be made to and for the benefit of such holders of Registrable Securities and that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement shall also be conditions precedent to the obligations of such holders of Registrable Securities. In the case of a registration requested by the C&D Fund pursuant to Section 3.1(a), Westinghouse shall not be required by the Company or the C&D Fund to make any representations or warranties to, or agreements with, the Company or the under writers other than as set forth in Section 3.4(e) and representations, warranties or agreements regarding Westinghouse and its intended method of distribution. (c) Selection of Underwriters. Whenever a registration requested ------------------------- pursuant to Section 3.1 is for an underwritten offering, the Company will have the right to select one or more underwriters to administer the offering at least one of which shall be an underwriter of nationally recognized standing, provided that, in the case of any such registration requested pursuant to - -------- Section 3.1(b), the selection of such underwriters by the Company shall be subject to the consent of Westinghouse, which consent shall not be unreasonably withheld. If the Company at any time proposes to register any of its securities under the Securities Act for sale for its own account and such securities are to be distributed by or through one or more underwriters, the Company will have the right to select one or more underwriters to administer the offering at least one of which shall be an underwriter of nationally recognized standing. 24

(d) Incidental Underwritten Offerings. Subject to the provisions of --------------------------------- the proviso to the first sentence of Section 3.2, if the Company at any time proposes to register any of its equity securities under the Securities Act (other than pursuant to Section 3.1 or pursuant to a Special Registration), whether or not for its own account, and such securities are to be distributed by or through one or more underwriters, the Company will give prompt written notice to all holders of Registrable Securities of its intention to do so and, if requested by any holder of Registrable Securities, will arrange for such underwriters to include the Registrable Securities to be offered and sold by such holder among those to be distributed by such underwriters. The holders of Registrable Securities to be distributed by such underwriters shall be parties to the underwriting agreement between the Company and such underwriters and may, at their option, require that any or all of the representations and warranties by, and the other agreements on the part of, the Company to and for the benefit of such underwriters shall also be made to and for the benefit of such holders of Registrable Securities and that any or all of the conditions precedent to the obligations of the underwriters under such underwriting agreement shall also be conditions precedent to the obligations of such holders of Registrable Securities. No such holder of Registrable Securities shall be required by the Company to make any representations or warranties to, or agreements with, the Company or the underwriters other than as set forth in Section 3.4(e) and representations, warranties or agreements regarding such holder and such holder's intended method of distribution. (e) Hold Back Agreements. If and whenever the Company proposes to -------------------- register any of its equity securities under the Securities Act for its own account (other than pursuant to a Special Registration) or is required to use its best efforts to effect the registration of any Registrable Securities under the Securities Act pursuant to Section 3.1 or 3.2, each holder of Registrable Securities agrees by acquisition of such Registrable Securities not to effect (other than pursuant to such registration) any public 25

sale or distribution, including, but not limited to, any sale pursuant to Rule 144 or Rule 144A, of any Registrable Securities, any other equity securities of the Company or any securities convertible into or exchangeable or exercisable for any equity securities of the Company for 120 days (180 days if such registration statement relates to the Initial Public Offering) after, and (assuming compliance by the Company with Section 3.4(f)) during the 20 days prior to, the effective date of such registration and the Company agrees to cause each holder of any equity security, or of any security convertible into or exchangeable or exercisable for any equity security, of the Company purchased from the Company at any time other than in a public offering to enter into a similar agreement with the Company. The Company further agrees not to effect (other than pursuant to such registration or pursuant to a Special Registration) any public sale or distribution, or to file any registration statement (other than such registration or a Special Registration) covering any, of its equity securities, or any securities convertible into or exchangeable or exercisable for such securities, during the 20 days prior to, and for 120 days (180 days if such registration statement relates to the Initial Public Offering) after, the effective date of such registration. (f) Notice of Impending Effective Date. The Company will give at ---------------------------------- least 20 days' written notice to each holder of Registrable Securities of the date when the Company expects, in its good faith judgment, that any registration pursuant to Section 3.1 or 3.2 will become effective (such notice to specify the expected effective date) and will respond promptly to any subsequent reasonable requests from any holder of Registrable Securities concerning the likely effective date of such registration. 3.5. Preparation; Reasonable Investigation. In connection with the ------------------------------------- preparation and filing of each registration statement registering Registrable Securities under the Securities Act, the Company will give the holders of such Registrable Securities so to be registered and their 26

underwriters, if any, and their respective counsel and accountants the opportunity to participate in the preparation of such registration statement, each prospectus included therein or filed with the Securities and Exchange Commission, and each amendment thereof or supplement thereto, and will give each of them such access to its books and records and such opportunities to discuss the business of the Company with its officers and the independent public accountants who have issued audit reports on its financial statements as shall be necessary, in the opinion of such holders' and such underwriters' respective counsel, to conduct a reasonable investigation within the meaning of the Securities Act. 3.6. Other Registrations. If and whenever the Company is required to ------------------- use its best efforts to effect the registration of any Registrable Securities under the Securities Act pursuant to Section 3.1 or 3.2, and if such registration shall not have been withdrawn or abandoned, the Company shall not be obligated to and shall not file any registration statement with respect to any of its securities (including Registrable Securities) under the Securities Act (other than a Special Registration), whether of its own accord or at the request or demand of any holder or holders of such securities, until a period of six months shall have elapsed from the effective date of such previous registration; and the Company shall so provide in any registration agreement with respect to any of its securities. 3.7. Indemnification. --------------- (a) Indemnification by the Company. In the event of any registration ------------------------------ of any Registrable Securities under the Securities Act pursuant to Section 3.1 or 3.2, the Company will indemnify and hold harmless the seller of such securities, its directors, officers, and employees, each other person who participates as an underwriter, broker or dealer in the offering or sale of such securities and each other person, if any, who controls such seller or any such participating person within the meaning of either Section 15 of 27

the Securities Act or Section 20 of the Exchange Act, against any and all losses, claims, damages or liabilities, joint or several, to which such seller or any such director, officer, employee, participating person or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged - untrue statement of a fact contained in any registration statement under which such securities were registered under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained therein or related thereto, or any amendment or supplement thereto, or (ii) any omission or alleged -- omission to state a fact required to be stated in any such registration statement, preliminary prospectus, final prospectus, summary prospectus, amendment or supplement or necessary to make the statements therein not misleading; and the Company will reimburse such seller and each such director, officer, employee, participating person and controlling person for any legal or any other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, liability, action or proceeding, provided -------- that the Company shall not be liable in any such case to the extent that any any loss, claim, damage, liability or expense arises out of or is based upon an untrue statement or omission made in such registration statement, any such preliminary prospectus, final prospectus, summary prospectus, amendment or supplement in reliance upon and in conformity with written information furnished to the Company by such seller or participating person expressly for use in the preparation thereof and provided, further, that the Company shall not be liable -------- ------- in any such case to the extent that any such loss, claim, damage, liability or expense arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission in the prospectus, if such untrue statement or alleged untrue statement or omission or alleged omission is completely corrected in an amendment or supplement to the prospectus and the seller of Registrable Securities thereafter fails to deliver such prospectus as so amended or supplemented prior 28

to or concurrently with the sale of Registrable Securities to the person asserting such loss, claim, damage, liability or expense after the Company had furnished such seller with a sufficient number of copies of the same or if the seller received notice from the Company of the existence of such untrue statement or alleged untrue statement or omission or alleged omission and the seller continued to dispose of Registrable Securities prior to the time of the receipt of either (A) an amended or supplemented prospectus which completely - corrected such untrue statement or omission or (B) a notice from the Company - that the use of the existing prospectus may be resumed. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such seller or any such director, officer, employee, participating person or controlling person and shall survive the transfer of such securities by such seller. (b) Indemnification by the Sellers. The Company may require, as a ------------------------------ condition to including any Registrable Securities in any registration statement filed pursuant to Section 3.3, that the Company shall have received an undertaking satisfactory to it from each of the prospective sellers of such securities, to indemnify and hold harmless (in the same manner and to the extent as set forth in Section 3.7(a)) the Company, each director of the Company, each officer of the Company who shall sign such registration statement and each other person, if any, who controls the Company within the meaning of the Securities Act, with respect to any statement in or omission from such registration statement, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereto, if such statement or omission was made in reliance upon and in conformity with written information furnished to the Company by such seller expressly for use in the preparation of such registration statement, preliminary prospectus, final prospectus, summary prospectus, amendment or supplement, provided that the liability of each such -------- seller will be in proportion to and limited to the net amount received by such seller (after deducting any underwriting discount 29

and expenses) from the sale of Registrable Securities pursuant to such registration statement. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Company or any such director, officer or controlling person and shall survive the transfer of such securities by such seller. (c) Notices of Claims, etc. Promptly after receipt by an indemnified ---------------------- party of notice of the commencement of any action or proceeding involving a claim referred to in the preceding paragraphs of this Section 3.7, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party hereunder, give written notice to the latter of the commencement of such action, provided that the failure of any indemnified party -------- to give notice as provided therein shall not relieve the indemnifying party of its obligations under the preceding paragraphs of this Section 3.7. In case any such action is brought against an indemnified party, the indemnifying party will be entitled to participate therein and to assume the defense thereof, jointly with any other indemnifying party similarly notified to the extent that it may wish, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof, provided that if -------- such indemnified party and the indemnifying party reasonably determine, based upon advice of their respective independent counsel, that a conflict of interest may exist between the indemnified party and the indemnifying party with respect to such action and that it is advisable for such indemnified party to be represented by separate counsel, such indemnified party may retain other counsel, reasonably satisfactory to the indemnifying party, to represent such indemnified party, and the indemnifying party shall pay all reasonable fees and expenses of such counsel. No indemnifying party, in the defense of any such claim or litigation, shall, except with the consent of such indemnified party, 30

which consent shall not be unreasonably withheld, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation. (d) Other Indemnification. Indemnification similar to that --------------------- specified in the preceding paragraphs of this Section 3.7 (with appropriate modifications) shall be given by the Company and each seller of Registrable Securities with respect to any required registration or other qualification of such Registrable Securities under any Federal or state law or regulation of governmental authority other than the Securities Act. (e) Other Remedies. If for any reason the foregoing indemnity is -------------- unavailable, or is insufficient to hold harmless an indemnified party, other than by reason of the exceptions provided therein, then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities or expenses party as well as any other relevant equitable considerations (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party on the one hand and the indemnified party on the other from the offering of Registrable Securities (taking into account the portion of the proceeds of the offering realized by each such party) or (ii) if the allocation provided by -- clause (i) above is not permitted by applicable law, or provides a lesser sum to the indemnified party than the amount hereinafter calculated, in such proportion as is appropriate to reflect not only the relative benefits received by the indemnifying party on the one hand and the indemnified party on the other but also the relative fault of the indemnifying party and the indemnified. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. No party shall be 31

liable for contribution under this Section 3.7(e) except to the extent and under such circumstances as such party would have been liable to indemnify under this Section 3.7 if such indemnification were enforceable under applicable law. (f) Officers and Directors. As used in this Section 3.7, the terms ---------------------- "officers" and "directors" shall include the partners of the holders of Registrable Securities which are partnerships. 4. Participation Rights. The C&D Fund shall not make any Qualifying -------------------- Sale, except pursuant to the following provisions of this Section 4. (a) Procedures for Qualifying Sales. At least 30 days prior to ------------------------------- making any Qualifying Sale, the C&D Fund will deliver a written notice (the "Sale Notice") to the Company, the holder of the Option and the holders of - ------------ Registrable Securities. The Sale Notice will fully disclose the identity of the prospective transferee and the terms and conditions of the proposed Qualifying Sale, including the class of Registrable Securities to be sold (the "Specified Securities"), the maximum amount of Specified Securities that the - ---------------------- prospective transferee is willing to purchase and the intended consummation date of such Qualifying Sale. The C&D Fund may not give a Sale Notice with respect to any Qualifying Sale unless both the C&D Fund and the prospective transferee shall be legally bound to complete such Qualifying Sale (subject only to the satisfaction of the conditions of such Qualifying Sale disclosed in such Sale Notice and compliance with this Section 4 and any Applicable Law). The C&D Fund will not consummate any Qualifying Sale until at least 30 days after the related Sale Notice has been given to the holder of the Option and the holders of Registrable Securities, unless the C&D Fund shall have received a notice from each holder of Specified Securities or securities presently convertible into or exchangeable or exercisable for Specified Securities (collectively, "Qualifying Securities") indicating whether or not such holder ---------------------- has elected to participate in such Qualifying Sale and the amount of 32

Specified Securities to be sold by each such holder so electing to participate has been finally determined pursuant hereto prior to the expiration of such 30- day period. Each holder of Qualifying Securities may elect to participate in the contemplated Qualifying Sale by giving written notice to the C&D Fund and the Company within 30 days after the C&D Fund has given the related Sale Notice to such holder. If a holder of Qualifying Securities elects to participate, such holder will be entitled to sell in the contemplated Qualifying Sale, at the same price and (subject to the immediately following sentence) on the same terms and conditions as set forth in the related Sale Notice, an amount of Specified Securities equal to the product of (i) the quotient determined by dividing (A) - - the amount of Specified Securities then held by such holder (including in such amount all Specified Securities issuable upon conversion, exchange or exercise of all Qualifying Securities then held by such holder) by (B) the aggregate -- amount of Specified Securities held by the C&D Fund and all holders of Qualifying Securities (other than the C&D Fund) so electing to participate (including in such aggregate amount all Specified Securities issuable upon conversion, exchange or exercise of Qualifying Securities then held by the C&D Fund and such holders) and (ii) the amount of Specified Securities such -- transferee has agreed to purchase in the contemplated Qualifying Sale. Notwithstanding the immediately preceding sentence, Westinghouse shall not be required in connection with any Qualifying Sale in which it elects to participate (x) to enter into any non-competition covenant or agreement having a - scope or duration beyond that contained in the Non-Competition Agreement dated the date hereof entered into by Westinghouse pursuant to the Acquisition Agreement or (y) other than in respect of representations, warranties, - covenants and agreements made solely on its own behalf, to undertake any liability in excess of its proportionate share (based on the amount of securities sold in such Qualifying Sale) for representations, warranties, covenants and agreements made jointly by the selling holders in such Qualifying Sale. If a holder of Qualifying Securities elects to participate in any Qualifying Sale, the C&D Fund will not 33

consummate such Qualifying Sale unless such holder has been afforded the opportunity to consummate simultaneously the sale by such holder of the amount of Specified Securities determined in accordance with the preceding sentence with respect to such holder. Each holder of Qualifying Securities proposing to include in any contemplated Qualifying Sale Specified Securities to be issued to such holder upon the conversion of other Qualifying Securities then held by such holder shall effect such conversion prior to the time of such Qualifying Sale. (b) Qualifying Sale Defined. The term "Qualifying Sale" shall mean ----------------------- ---------------- any sale or transfer of securities of the Company by the C&D Fund other than any sale or transfer (i) pursuant to a bona fide firm commitment underwritten public - offering (A) pursuant to a registration under the Securities Act effected - pursuant to Section 3.1 or (B) pursuant to a registration under the Securities - Act not effected pursuant to Section 3.1 if Section 3.2 applies to such registration and, in each of clauses (A) and (B), the Company has complied with all its obligations under Section 3 with respect to such registration, (ii) if -- the Company is subject to the reporting requirements of the Exchange Act, in transactions that comply with the manner of sale requirements set forth in Rule 144(f)) or (iii) to Individual Investors or Management Stockholders. --- 5. Investors' Rights to Purchase Additional Capital Stock. ------------------------------------------------------ 5.1. C&D Sale. If, prior to the consummation of a Specified Public -------- Offering, the Company shall propose to issue any additional shares of its capital stock (or any securities that may be exercised or exchanged for or converted into such capital stock) to the C&D Fund or any Affiliate of the C&D Fund (such Persons to whom the Company proposes to issue securities are referred to collectively as the "C&D Offeree", and such issuance is referred to as a "C&D ----------- --- Sale"), the Company shall offer to the holder of the Option and each holder of - ---- Registrable Securities (other than 34

the C&D Offeree) that is an accredited investor (as defined in Rule 501 of Regulation D under the Securities Act) (each, an "Eligible Holder") the right to --------------- acquire such holder's Allocated Amount of such securities (an "Offer"). ----- Notwithstanding the foregoing, none of the following transactions shall constitute a C&D Sale: the issuance by the Company of any shares of its capital stock (or any securities that may be exercised or exchanged for or converted into such capital stock) (A) pursuant to the Fund Stock Subscription - Agreement or the Capital Call Agreement (each as in effect on the date hereof), (B) in exchange for Class A Common Stock, (C) upon conversion of Class B Common - - Stock or (D) as a dividend or other distribution (including, but not limited to, - in connection with any merger, consolidation or other reorganization) made pro --- rata to the holders of the Common Stock outstanding on the record date for such - ---- dividend or distribution. 5.2. Offer Procedures. ---------------- (a) Procedures. The Company shall make an Offer by giving to each ---------- Eligible Holder at least 30 Business Days' prior written notice of the proposed C&D Sale. Such notice will (i) identify the class and number of shares or - amount of securities proposed to be issued (the "Offered Securities"), the ------------------- proposed date of issuance and the price and other terms of the issuance and (ii) -- constitute an offer to issue to each such Eligible Holder its Allocated Amount of the Offered Securities at the same price and on the same other terms (subject to Section 5.2(c)) as are proposed for such C&D Sale, which offer shall remain open for a period of 15 Business Days from the date such notice is given by the Company. Each Eligible Holder desiring to accept such Offer shall give written notice to the Company prior to the end of the 15-Business Day period of such Offer. Such notice (a "Notice of Acceptance") will (A) set forth the maximum -------------------- - amount of the Offered Securities which such Eligible Holder elects to purchase (such Eligible Holder's "Subscribed Amount") and (B) constitute an acceptance of ----------------- - the Offer with respect to such Eligible Holder's Allocated Amount of the 35

Offered Securities. If any such Eligible Holder fails to give a Notice of Acceptance, such Eligible Holder shall be deemed to have rejected such Offer in full. At the closing of the C&D Sale, each Eligible Holder who shall have timely accepted the related Offer pursuant to this Section 5.2(a) (each, an "Accepting Holder") shall acquire from the Company, and the Company shall issue - ----------------- to such Eligible Holder, its Allocated Amount of the Offered Securities at the same price and on the same other terms (subject to Section 5.2(c)) as such C&D Sale. The C&D Offeree shall be entitled to acquire at the closing of the C&D Sale its Allocated Amount of the Offered Securities. Any Offered Securities not issued at the C&D Sale may not thereafter be sold or otherwise issued by the Company to the C&D Fund or any Affiliate of the C&D Fund until they are again offered to the Eligible Holders under the procedures specified in this Section 5(a). (b) Allocated Amount Defined. For the purposes of Section 5.2(a), ------------------------ the term "Allocated Amount" shall mean, with respect to each Accepting Holder ---------------- and the C&D Offeree (collectively, the "Participants") in a C&D Sale, the aggregate amount of the Offered Securities in such C&D Sale allocated to such Participant in a series of calculations (each, an "Allocation Calculation") as ---------------------- follows: first, each Participant shall be allocated an amount of the Offered Securities in such C&D Sale equal to the lesser of (a) such Participant's - Subscribed Amount of such Offered Securities and (b) such Participant's - Proportionate First Share of such Offered Securities; thereafter, in each subsequent Allocation Calculation for such C&D Sale, each Participant whose Subscribed Amount of such Offered Securities exceeds the aggregate amount of Offered Securities allocated to such Participant in prior Allocation Calculations in respect of such C&D Sale shall be allocated an additional amount of Offered Securities equal to the lesser of (i) such Participant's - Proportionate Subsequent Share of such Offered Securities and (ii) the excess of -- such Participant's Subscribed Amount of such Offered Securities over the aggregate amount of Offered Securities allocated to such Participant 36

in all prior Allocation Calculations in respect of such C&D Sale. For the purposes of this Section 5.2(a), the term "Proportionate First Share" shall ------------------------- mean, with respect to each Participant in a C&D Sale, an amount of the Offered Securities in such C&D Sale that is equal to the product of (a) the quotient - determined by dividing (i) the percentage of the outstanding Common Stock (on a - fully diluted basis) held by such Participant by (ii) the aggregate percentage -- of the outstanding Common Stock (on a fully diluted basis) held by all Participants in such C&D Sale and (b) the aggregate amount of such Offered - Securities. For the purposes of this Section 5.2(b), the term "Proportionate ------------- Subsequent Share" shall mean, with respect to each Participant in a C&D Sale - ---------------- being allocated a Proportionate Subsequent Share of Offered Securities in an Allocation Calculation for such C&D Sale, an amount of the Offered Securities in such C&D Sale equal to the product of (a) the quotient determined by dividing - (i) the percentage of the outstanding Common Stock (on a fully diluted basis) - held by such Participant by (ii) the aggregate percentage of the outstanding -- Common Stock (on a fully diluted basis) held by all Participants being allocated a Proportionate Subsequent Share of Offered Securities in such Allocation Calculation and (b) the aggregate amount of the Offered Securities - not allocated to the Participants in such C&D Sale in any prior Allocation Calculation. (c) Terms of Offer. Notwithstanding Section 5.2(a), if the terms of -------------- any C&D Sale provide for the payment by the C&D Offeree of consideration other than cash, then the purchase price payable by each Accepting Holder (other than Westinghouse) per unit of Offered Securities shall be an amount in cash equal to the fair market value of the aggregate consideration payable by the C&D Offeree per unit of Offered Securities. For the purpose of determining the fair market value of any noncash consideration, (i) any portion of such consideration in the - form of securities shall be valued at the arithmetical average of the closing sale prices of such securities over the five trading days immediately preceding the relevant date on the national securities exchange on which such securities are listed, or, 37

if not so listed, as reported by the National Association of Securities Dealers Automated Quotations System, or, if not so reported, at the average of the high bid and low asked quotations for the securities as reported by the National Quotations Bureau Incorporated or a similar organization, or, if no price quotations are available, such securities shall be valued by the Board of Directors of the Company in good faith as of the relevant date or, at the election (which shall be made in its Notice of Acceptance) and expense of an Accepting Holder which has succeeded by assignment to Westinghouse's rights under this Section 5 (other than Section 5.2(d)) in respect of Registrable Securities or the Option transferred by Westinghouse to such Accepting Holder, by an independent valuer with expertise in valuing such securities selected by the Company with the approval of such Accepting Holder, such approval not to be unreasonably withheld; and (ii) any other portion of such consideration shall be -- valued by the Board of Directors of the Company in good faith as of the relevant date or, at the election (which shall be made in its Notice of Acceptance) and expense of such an Accepting Holder, by an independent valuer with expertise in valuing such consideration selected by the Company with the approval of such Accepting Holder, such approval not to be unreasonably withheld. (d) Election as to Form of Consideration. Notwithstanding Section ------------------------------------ 5.2(a), if Westinghouse elects to exercise its rights under Section 5.2(a) with respect to any C&D Sale the terms of which provide for payment in consideration other than cash, Westinghouse may, at its option, make such payment in the form of consideration provided by such terms (including, if the consideration consists in whole or in part of the delivery of any debt security of any Person or other promise of any Person to pay cash, by delivery of a security or other promise of Westinghouse, of the same tenor) or in cash equal to the fair market value of such consideration. For the purpose of determining the fair market value of any non-cash consideration, (i) any portion of such - consideration in the form of securities shall be valued at the arithmetical average of the closing sale 38

prices of such securities over the five trading days immediately preceding the relevant date on the national securities exchange on which such securities are listed, or, if not so listed, as reported by the National Association of Securities Dealers Automated Quotations System, or, if not so reported, at the average of the high bid and low asked quotations for the securities as reported by the National Quotations Bureau Incorporated or a similar organization, or, if no price quotations are available, such securities shall be valued by the Board of Directors of the Company in good faith as of the relevant date or, at the election (which shall be made in its Notice of Acceptance) and expense of Westinghouse, by an independent valuer with expertise in valuing such securities selected by the Company with the prior approval of Westinghouse, such approval not to be unreasonably withheld; and (ii) any other portion of such -- consideration shall be valued by the Board of Directors of the Company in good faith as of the relevant date or, at the election (which shall be made in its Notice of Acceptance) and expense of Westinghouse, by an independent valuer with expertise in valuing such consideration selected by the Company with the prior approval of Westinghouse, such approval not to be unreasonably withheld. 6.

Unless otherwise determined by the Committee at the Grant Date, the - -------- Committee shall provide in each Option Agreement governing Options granted hereunder that (a) Holding or the Company and the C&D Fund shall have successive - rights to purchase any exercisable Options from the Participant upon the termination of his employment prior to a Public Offering and (b) the - Participant may require Holding to repurchase his then exercisable Options upon the termination of the Participant's employment (i) due to an Extraordinary - Termination prior to a Public Offering or (ii) by Holding, the Company or any -- Subsidiary other than for Cause prior to a Public Offering, in each case for a purchase price per Option equal to the excess, if any, of (x) the Fair Market - Value on the date of termination over (y) the exercise price per share of Common - Stock pursuant to such Options, and upon such additional terms and conditions as are set forth in Section 4 of the Option Agreement attached hereto as Exhibit A. The foregoing right of a Participant to require Holding to repurchase any exercisable Options shall be subject to the Company having the ability to do so under the terms of its financing arrangements and under Delaware law. 10

Section 8. Change in Control ----------------------------- 8.1. Accelerated Vesting and Payment. Unless the Committee shall ------------------------------- otherwise determine in the manner set forth in Section 8.2, in the event of a Change in Control, each Option shall be cancelled in exchange for a payment in cash of an amount equal to the excess, if any, of the Change in Control Price over the exercise price for such Option. 8.2. Alternative Options. Notwithstanding Section 8.1, no ------------------- cancellation, acceleration of exercisability, vesting or cash settlement or other payment shall occur with respect to any Option if the Committee reasonably determines in good faith, prior to the occurrence of a Change in Control, that such Option shall be honored or assumed, or new rights substituted therefor (such honored, assumed or substituted Option being hereinafter referred to as an "Alternative Option") by the New Employer, provided that any such -------- Alternative Option must: (a) provide the Participant that held such Option with rights and entitlements substantially equivalent to or better than the rights, terms and conditions applicable under such Option, including, but not limited to, an identical or better exercise and vesting schedule, identical or better timing and methods of payment and, if the Alternative Options or the securities underlying them are not publicly traded, identical or better rights to require Holding or the New Employer to repurchase the Alternative Options; (b) have substantially equivalent economic value to such Option (determined at the time of the Change in Control); and (c) have terms and conditions which provide that in the event that such Participant suffers an Involuntary Termination within two years following a Change in Control: 11

(i) any conditions on such Participant's rights under, or any restrictions on transfer or exercisability applicable to, each such Alternative Option shall be waived or shall lapse, as the case may be; or (ii) such Participant shall have the right to surrender such Alternative Option within 30 days following such termination in exchange for a payment in cash equal to the excess of the Fair Market Value of the equity security subject to the Alternative Option over the price, if any, that such Participant would be required to pay to exercise such Alternative Option. Section 9. Amendment, Modification, and ---------------------------------------- Termination of the Plan ----------------------- The Board at any time may terminate or suspend the Plan, and from time to time may amend or modify the Plan. No amendment, modification, termination or suspension of the Plan shall in any manner adversely affect any Option theretofore granted under the Plan, without the consent of the Participant holding such Option. Shareholder approval of any such amendment, modification, termination or suspension shall be obtained to the extent mandated by applicable law, or if otherwise deemed appropriate by the Committee. Section 10. Miscellaneous Provisions ------------------------------------- 10.1. Nontransferability of Awards.

the purchase rights described in Section 7.4) and the Option Agreement covering such Options as if such beneficiary or estate were the Participant. All rights with respect to Options granted to a Participant under the Plan shall be exercisable during his life-time by such Participant only.

Beneficiary Designation. Each Participant under the Plan may ----------------------- from time to time name any beneficiary or beneficiaries (who may be named contingently or successively) by whom any right under the Plan is to be exercised in case of his death. Each designation will revoke all prior designations by the same Participant, shall be in a form reasonably prescribed by the Committee, and will be effective only when filed by the Participant in writing with the Committee during his lifetime. 10.3. No Guarantee of Employment or Participation. Nothing in the ------------------------------------------- Plan or in any Option Agreement shall interfere with or limit in any way the right of Holding, the Company or any Subsidiary to terminate any Participant's employment at any time, or confer upon any Participant any right to continue in the employ of Holding, the Company or any Subsidiary. No Employee shall have a right to be selected as a Participant or, having been so selected, to receive any Options. 10.4. Tax Withholding. The Company or the Subsidiary employing a --------------- Participant shall have the power to withhold, or to require such Participant to remit to the Company or such Subsidiary, subject to such other arrangements as the Committee may set forth in the Option Agreement to which such Participant is a party, an amount sufficient to satisfy all federal, state, local and foreign withholding tax requirements in respect of any Option granted under the Plan. 13

10.5. Indemnification. Each person who is or shall have been a --------------- member of the Committee, the Board or any other committee of the Board shall be indemnified and held harmless by the Company and Holding to the fullest extent permitted by law from and against any and all losses, costs, liabilities and expenses (including any related attorneys' fees and advances thereof) in connection with, based upon or arising or resulting from any claim, action, suit or proceeding to which he may be made a party or in which he may be involved by reason of any action taken or failure to act under or in connection with the Plan and from and against any and all amounts paid by him in settlement thereof, with the Company's approval, or paid by him in satisfaction of any judgment in any such action, suit or proceeding against him, provided that he shall give the -------- Company an opportunity, at its own expense, to defend the same before he undertakes to defend it on his own behalf. The foregoing right of indemnification shall not be exclusive and shall be independent of any other rights of indemnification to which such persons may be entitled under Holding's or the Company's Certificate of Incorporation or By-laws, by contract, as a matter of law, or otherwise. 10.6. No Limitation on Compensation. Nothing in the Plan shall be ----------------------------- construed to limit the right of Holding, the Company or any Subsidiary to establish other plans or to pay compensation to its employees, in cash or property, in a manner that is not expressly authorized under the Plan. 10.7.

10.8. Freedom of Action.

Term of Plan. The Plan shall be effective as of the Effective ------------ Date. The Plan shall continue in effect, unless sooner terminated pursuant to Section 9, until the tenth anniversary of the Effective Date.

Except as otherwise required by law, no ---------------- Participant holding any Options granted under the Plan shall have any right, in respect of such Options, to vote on any matter submitted to Holding's stockholders until such time as the shares of Common Stock issuable upon exercise of such Options have been so issued. 10.11. Governing Law. The Plan, and all agreements hereunder, shall ------------- be construed in accordance with and governed by the laws of the State of New York, except to the extent that the corporate law of the State of Delaware specifically and mandatorily applies. 15

EXHIBIT 10.4 FORM OF STOCK OPTION AGREEMENT ---------------------- STOCK OPTION AGREEMENT, dated as of December 31, 1996, between CDW Holding Corporation, a Delaware corporation (the "Company"), and the Grantee whose name appears on the signature page hereof (the "Grantee").

2. Exercisability. Except as otherwise provided in this Agreement, -------------- the Option shall become available for exercise, subject to the provisions hereof, in one-third installments on each of the first, third and fifth anniversaries of the date of this Agreement, provided that the Committee may -------- accelerate the exercisability of any Option, all Options or any class of Options, at any time and from time to time. Shares eligible for purchase may thereafter be purchased, subject to the provisions hereof, and pursuant to and subject to the provisions contained in the Management Stock Subscription Agreement (as defined in Section 5) related to such Shares, at any time and from time to time on or after such anniversary until the date one day prior to the date on which the Option terminates. 3.

Notwithstanding anything else contained in this Agreement, if the Grantee's Active Employment is terminated by the Company for Cause, then all Options (whether or not then exercisable) shall terminate and be canceled immediately upon such termination, regardless of whether then exercisable. Nothing in this Agreement shall be deemed to confer on the Grantee any right to continue in the employ of the Company or any of its direct or indirect subsidiaries, or to interfere with or limit in any way the right of the Company or any of its direct or indirect subsidiaries to terminate such employment at any time. 4. Restrictions on Exercise; Non-Transferability of Option; -------------------------------------------------------- Repurchase of Option. - -------------------- (a) Restrictions on Exercise. The Option may be exercised only with ------------------------ respect to full shares of Common Stock. No fractional shares of Common Stock shall be issued. Notwithstanding any other provision of this Agreement, the Option may not be exercised in whole or in part, and no certificates representing Shares shall be delivered, (i) unless all requisite approvals and - consents of any governmental authority of any kind having jurisdiction over the exercise of options shall have been secured, (ii) unless the purchase of the -- Shares upon the exercise of the Option shall be exempt from registration under applicable U.S. federal and state securities laws, and applicable non-U.S. securities laws, or the Shares shall have been registered under such laws, (iii) --- unless all applicable U.S. federal, state 3

and local and non-U.S. tax withholding requirements shall have been satisfied and (iv) if such exercise would result in a violation of the terms or provisions -- of or a default or an event of default under any of the Financing Agreements (as such term is defined in Section 9).

(b) Non-Transferability of Option. Except as contemplated by Section ----------------------------- 4(c), the Option may be exercised only by the Grantee or by his estate. Except as contemplated by Section 4(c), the Option is not assignable or transferable, in whole or in part, and it may not, directly or indirectly, be offered, transferred, sold, pledged, assigned, alienated, hypothecated or otherwise disposed of or encumbered (including without limitation by gift, operation of law or otherwise) other than by will or by the laws of descent and distribution to the estate of the Grantee upon his death, provided that the deceased Grantee's beneficiary or the representative of his estate shall acknowledge and agree in writing, in a form reasonably acceptable to the Company, to be bound by the provisions of this Agreement and the Plan as if such beneficiary or the estate were the Grantee. (c) Repurchase of Option on Termination of Employment. ------------------------------------------------- (i) Termination of Employment. If the Grantee's Active ------------------------- Employment is terminated for any reason, the Company or WESCO shall have an option to purchase all (but not less than all) of the portion of the Option that is exercisable on the effective date of termination of Active Employment (the "Covered Option"), and shall have 30 days from the date of the 4

Grantee's termination (the "First Purchase Period") during which to give notice in writing to the Grantee (or if his Active Employment was terminated by his death, his estate) of its election to exercise or not to exercise such right to purchase the Covered Option. The Company and WESCO hereby undertake to use reasonable efforts to act as promptly as practicable following such termination to make such election. If the Company or WESCO fails to give notice that it intends to exercise its right to purchase the Covered Option within the First Purchase Period, the C&D Fund shall have the right to purchase the Covered Option and shall have until the expiration of the earlier of (x) 30 days following the end of the - First Purchase Period, or (y) 30 days from the date of receipt by the C&D - Fund of written notice that neither the Company nor WESCO does not intend to exercise such right (the "Second Purchase Period"), to give notice in writing to the Grantee (or his estate) of the C&D Fund's exercise of its right to purchase the Covered Option. If the rights to purchase the Covered Option of the Company and the C&D Fund granted in this subsection are not exercised as provided herein, the Grantee (or his estate) shall be entitled to retain the Covered Option, subject to all of the provisions of this Agreement. (ii) Purchase Price, etc. All purchases pursuant to this ------------------- Section 4(c) by the Company or the C&D Fund shall be for a purchase price and in the manner prescribed by Sections 4(g), (h) and (i). (d) Certain Definitions. As used in this Agreement the following ------------------- terms shall have the following meanings: (i) "Active Employment" shall mean active employment with the ----------------- Company or any direct or indirect subsidiary of the Company. (ii) "Cause" shall mean (A) the willful failure by the Grantee ----- - substantially to perform his 5

employment-related duties (other than any such failure due to physical or mental illness) after a demand for substantial performance is delivered to the Grantee by the Director of Human Resources, which notice identifies the manner in which the Director of Human Resources, believes that the Grantee has not substantially performed his employment-related duties, (B) - the engaging by the Grantee in willful and serious misconduct that is injurious to the Company or any of its affiliates, (C) the conviction of - the Grantee of, or the entering by the Grantee of a plea of nolo contendere ---- ---------- to, a crime that constitutes a felony, or (D) the breach (including but not - limited to the material or willful failure to cure a breach) by the Grantee of any written covenant or agreement with the Company or any of its affiliates not to disclose any information pertaining to the Company or any of its affiliates or not to compete or interfere with the Company or any of its affiliates. (iii) "Retirement at Normal Retirement Age" shall mean retirement ----------------------------------- at age 65 or later. (iv) "Permanent Disability" shall mean a physical or mental -------------------- disability or infirmity that prevents the performance of such Grantee's employment-related duties lasting (or likely to last, based on competent medical evidence presented to the Director of Human Resources) for a continuous period of six months or longer. The Director of Human Resource's reasoned and good faith judgment of Permanent Disability shall be final, binding and conclusive on all parties hereto and shall be based on such competent medical evidence as shall be presented to it by the Grantee or by any physician or group of physicians or other competent medical expert employed by the Grantee or the Company to advise the Director of Human Resources. (e) Notice of Termination. The Company shall give written notice of --------------------- any termination of the Grantee's 6

Active Employment to the C&D Fund, except that if such termination (if other than as a result of death) is by the Grantee, the Grantee shall give written notice of such termination to the Company and the Company shall give written notice of such termination to the C&D Fund. (f) Public Offering. In the event that an underwritten public --------------- offering in the Untied States of the Common Stock led by one or more underwriters at least one of which is an underwriter of nationally recognized standing (a "Public Offering") has been consummated, neither the Company nor the C&D Fund shall have any rights to purchase the Covered Option pursuant to this Section 4. (g) Purchase Price. Subject to Section 9(c), the purchase price to be -------------- paid to the Grantee (or his estate) for the Covered Option (the "Purchase Price") shall be equal to the difference between (A) the fair market value (the - "Fair Market Value") of the Shares which may be purchased upon exercise of the Covered Option as of the effective date of the termination of employment that gives rise to the right to repurchase and (B) the aggregate exercise price of - the Covered Option. Whenever determination of the Fair Market Value of the Shares is required by this Agreement, such Fair Market Value shall be such amount as is determined in good faith by the Board. In making a determination of Fair Market Value, the Board shall give due consideration to such factors as it deems appropriate, including, without limitation, the earnings and certain other financial and operating information of the Company in recent periods, the potential value of the Company as a whole, the future prospects of the Company and the industries in which it competes, the history and management of the Company, the general condition of the securities markets, the fair market value of securities of companies engaged in businesses similar to those of the Company and a valuation of the Shares. The valuation that is in effect as of December 31, 1996, which was prepared by an independent valuation firm chosen by the Board, shall be used to determine the Purchase Price. The determination of Fair Market Value will not give 7

effect to any restrictions on transfer of the Shares or the fact that such Shares would represent a minority interest in the Company. The Fair Market Value as determined in good faith by the Board in the absence of fraud shall be binding and conclusive upon all parties hereto and the C&D Fund, and in any event the Grantee agrees to accept and shall not challenge any determination of Fair Market Value made by the Board, so long as the Fair Market Value thus determined is at least equal to $195.40 per share. If the Company subdivides (by any stock split, stock dividend or otherwise) the Common Stock into a greater number of shares, or combines (by reverse stock split or otherwise) the Common Stock into a smaller number of shares after the Board shall have determined the Purchase Price for the Shares (without taking into consideration such subdivision or combination) and prior to the consummation of the purchase, the Purchase Price shall be appropriately adjusted to reflect such subdivision or combination, and the Board's determination as to any such adjustment in good faith shall be binding and conclusive on all parties hereto and the C&D Fund. (h) Payment. Subject to Section 9, the completion of a purchase ------- pursuant to this Section 4 shall take place at the principal office of the Company on the tenth business day following the receipt by the Grantee of the C&D Fund's or the Company's notice of its exercise of the right to purchase the Covered Option pursuant to Section 4(c). The Purchase Price shall be paid by delivery to the Grantee of a certified or bank check for the Purchase Price payable to the order of the Grantee, against delivery of such instruments as the Company may reasonably request signed by the Grantee, free and clear of all security interests, liens, claims, encumbrances, charges, options, restrictions on transfer, proxies and voting and other agreements of whatever nature. (i) Application of the Purchase Price to Certain Loans. The Grantee -------------------------------------------------- agrees that the Company and the C&D Fund shall be entitled to apply any amounts to be paid by the Company or the C&D Fund, as the case may be, to repurchase 8

the Covered Option pursuant to this Section 4 to discharge any indebtedness of the Grantee to the Company or any of its direct or indirect subsidiaries, or indebtedness that is guaranteed by the Company or any of its direct or indirect subsidiaries, including, but not limited to, any indebtedness of the Grantee incurred to purchase any shares of Common Stock. (j) Withholding. Whenever Shares are to be issued pursuant to the ----------- Option, the Company may require the recipient of the Shares to remit to the Company an amount sufficient to satisfy any applicable U.S. federal, state and local and non-U.S. tax withholding requirements. In the event any cash is paid to the Grantee pursuant to this Section 4, the Company shall have the right to withhold an amount from such payment sufficient to satisfy any applicable U.S. federal, state and local and non-U.S. tax withholding requirements. If shares of Common Stock are traded on a U.S. national securities exchange or bid and ask prices for shares of Common Stock are quoted on the Nasdaq National Market ("NASDAQ") operated by the National Association of Securities Dealers, Inc., the Company may, if requested by the Grantee, withhold shares to satisfy applicable withholding requirements, subject to the provisions of the Plan and any rules adopted by the Board or the Committee regarding compliance with applicable law, including, but not limited to, Section 16(b) of the U.S. Securities Exchange Act of 1934, as amended (the "Exchange Act"). 5. Manner of Exercise. To the extent that the Option shall have ------------------ become and remains exercisable as provided in Section 2 and subject to such reasonable administrative regulations as the Board or the Committee may have adopted, the Option may be exercised, in whole or in part, by notice to the Secretary of the Company in writing given 15 business days prior to the date on which the Grantee will so exercise the Option (the "Exercise Date"), specifying the number of Shares with respect to which the Option is being exercised (the "Exercise Shares") and the Exercise Date, provided that if shares of Common Stock are traded on a U.S. national 9

securities exchange or bid and ask prices for shares of Common Stock are quoted over NASDAQ, notice may be given five business days before the Exercise Date. On or before the Exercise Date, the Company and the Grantee shall enter into a Management Stock Subscription Agreement (the "Management Stock Subscription Agreement") substantially in the form attached hereto as Annex 1, or in such other form as may be agreed upon by the Company and the Grantee, such Management Stock Subscription Agreement to contain (unless a Pubic Offering shall have occurred prior to the Exercise Date) provisions corresponding to Section 4(c) hereof. In accordance with the Management Stock Subscription Agreement, (a) on - or before the Exercise Date, the Grantee shall deliver to the Company full payment for the Exercise Shares in United States dollars in cash, or cash equivalent satisfactory to the Company, and in an amount equal to the product of the number of Exercise Shares and $195.40 (the "Exercise Price") and (b) on - the Exercise Date, the Company shall deliver to WESCO to hold on behalf of the Grantee a certificate or certificates representing the Exercise Shares, registered in the name of the Grantee. If shares of Common Stock are traded on a U.S. national securities exchange or bid and ask prices for shares of Common Stock are quoted over NASDAQ, the Grantee may, in lieu of cash, tender shares of Common Stock having a market price on the Exercise Date equal to the Exercise Price or may deliver a combination of cash and shares of Common Stock having a market price equal to the difference between the Exercise Price and the amount of such cash as payment of the Exercise Price, subject to such rules and regulations as may be adopted by the Board or the Committee to provide for the compliance of such payment procedure with applicable law, including Section 16(b) of the Exchange Act. The Company may require the Grantee to furnish or execute such other documents as the Company shall reasonably deem necessary (i) - to evidence such exercise, (ii) to determine whether registration is then -- required under the U.S. Securities Act of 1933, as amended (the "Securities Act"), and (iii) to comply with or satisfy the requirements of the Securities --- Act, applicable state or non-U.S. securities laws or any other law. Prior to a public 10

offering, Holding shall deliver to WESCO to hold on behalf of the Grantee, a certificate or certificates representing the shares of Common Stock acquired upon the exercise thereof. 6. Grantee's Representations, Warranties and Covenants. --------------------------------------------------- (a) Investment Intention.

available with respect to the sales of any securities of the Company and the Company has made no covenant to make Rule 144 available, (v) when and if the - Exercise Shares may be disposed of without registration in reliance upon Rule 144, such disposition can be made only in limited amounts in accordance with the terms and conditions of such Rule, (vi) the Company does not plan to file -- reports with the Commission or make public information concerning the Company available unless required to do so by law or by the terms of its Financing Agreements (as hereinafter defined), (vii) if the exception afforded by Rule 144 --- is not available, sales of the Exercise Shares may be difficult to effect because of the absence of public information concerning the Company, (viii) a ---- restrictive legend in the form heretofore set forth shall be placed on the certificates representing the Exercise Shares and (ix) a notation shall be -- made in the appropriate records of the Company indicating that the Exercise Shares are subject to restrictions on transfer set forth in this Agreement and, if the Company should in the future engage the services of a stock transfer agent, appropriate stop-transfer restrictions will be issued to such transfer agent with respect to the Exercise Shares. (d) Compliance with Rule 144. If any of the Exercise Shares are to be ------------------------ disposed of in accordance with Rule 144 under the Securities Act, the Grantee shall transmit to the Company an executed copy of Form 144 (if required by Rule 144) no later than the time such form is required to be transmitted to the Commission for filing and such other documentation as the Company may reasonably require to assure compliance with Rule 144 in connection with such disposition.

Alternative Options. Notwithstanding Section 8.1, no ------------------- cancellation, acceleration of exercisability, vesting or cash settlement or other payment shall occur with respect to any Option if the Committee reasonably determines in good faith, prior to the occurrence of a Change in Control, that such Option shall be honored or assumed, or new rights substituted therefor (such honored, assumed or substituted Option being hereinafter referred to as an "Alter- 12

native Option") by the New Employer, provided that any such Alternative Option -------- must: (a) provide the Participant that held such Option with rights and entitlements substantially equivalent to or better than the rights, terms and conditions applicable under such Option, including, but not limited to, an identical or better exercise and vesting schedule, identical or better timing and methods of payment and, if the Alternative Options or the securities underlying them are not publicly traded, identical or better rights to require Holding or the New Employer to repurchase the Alternative Options; (b) have substantially equivalent economic value to such Option (determined at the time of the Change in Control); and (c) have terms and conditions which provide that in the event that such Participant suffers an Involuntary Termination within two years following a Change in Control: (i) any conditions on such Participant's rights under, or any restrictions on transfer or exercisability applicable to, each such Alternative Option shall be waived or shall lapse, as the case may be; or (ii) such Participant shall have the right to surrender such Alternative Option within 30 days following such termination in exchange for a payment in cash equal to the excess of the Fair Market Value of the equity security subject to the Alternative Option over the price, if any, that such Participant would be required to pay to exercise such Alternative Option. 13

Section 9. Amendment, Modification, and ---------------------------------------- Termination of the Plan ----------------------- The Board at any time may terminate or suspend the Plan, and from time to time may amend or modify the Plan.

Indemnification. Each person who is or shall have been a member --------------- of the Committee, the Board or any other committee of the Board shall be indemnified and held harmless by the Company and Holding to the fullest extent permitted by law from and against any and all losses, costs, liabilities and expenses (including any related attorneys' fees and advances thereof) in connection with, based upon or arising or resulting from any claim, action, suit or proceeding to which he may be made a party or in which he may be involved by reason of any action taken or failure to act under or in connection with the Plan and from and against any and all amounts paid by him in settlement thereof, with the Company's approval, or paid by him in satisfaction of any judgment in any such action, suit or proceeding against him, provided that he shall give the -------- Company an opportunity, at its own expense, to defend the same before he undertakes 15

Contribution. ------------ 7

(a) Except to the extent that Section 3(b) is applicable, if for any reason the indemnity provided for in Section 2(a) is unavailable or is insufficient to hold harmless any Indemnitee from any of the Obligations covered by such indemnity, then Holding and the Company, jointly and severally, shall contribute to the amount paid or payable by such Indemnitee as a result of such Obligation in such proportion as is appropriate to reflect (i) the relative - fault of each of Holding, the Company and their Subsidiaries, on the one hand, and such Indemnitee, on the other, in connection with the state of facts giving rise to such Obligation, (ii) if such Obligation results from, arises out of, is -- based upon or relates to any Securities Offering, the relative benefits received by each of Holding, the Company and their Subsidiaries, on the one hand, and such Indemnitee, on the other, from such Securities Offering and (iii) if --- required by applicable law, any other relevant equitable considerations. (b) If for any reason the indemnity specifically provided for in Section 2(b) is unavailable or is insufficient to hold harmless any Indemnitee from any of the Obligations covered by such indemnity, then Holding and the Company,jointly and severally, shall contribute to the amount paid or payable by such Indemnitee as a result of such Obligation in such proportion as is appropriate to reflect (i) the relative fault of each of Holding, the Company - and their Subsidiaries, on the one hand, and such Indemnitee, on the other, in connection with the information contained in or omitted from any Related Document, which inclusion or omission resulted in the inaccuracy or breach of or default under any representation, warranty, covenant or agreement therein, or which information is or is alleged to be untrue, required to be stated therein or necessary to make the statements therein not misleading, (ii) the relative -- benefits received by Holding, the Company and their Subsidiaries, on the one hand, and such Indemnitee, on the other, from such Securities Offering and (iii) --- if required 8

by applicable law, any other relevant equitable considerations. (c) For purposes of Section 3(a), the relative fault of each of Holding, the Company and their Subsidiaries, on the one hand, and of the Indemnitee, on the other, shall be determined by reference to, among other things, their respective relative intent, knowledge, access to information and opportunity to correct the state of facts giving rise to such Obligation. For purposes of Section 3(b), the relative fault of each of Holding, the Company and their Subsidiaries, on the one hand, and of the Indemnitee, on the other, shall be determined by reference to, among other things, (i) whether the included or - omitted information relates to information supplied by Holding, the Company or a Subsidiary, on the one hand, or by such Indemnitee, on the other, and (ii) their -- respective relative intent, knowledge, access to information and opportunity to correct such inaccuracy, breach, default, untrue or alleged untrue statement, or omission or alleged omission.

(d) The parties hereto acknowledge and agree that it would not be just and equitable if contributions pursuant to Section 3(a) or 3(b) were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in such respective Section. Holding and the Company shall not be liable under Section 3(a) or 3(b), as applicable, for contribution to the amount paid or payable by any Indemnitee except to the extent and under such circumstances as Holding or the Company would have been 9

liable to indemnify, defend and hold harmless such Indemnitee under the corresponding Section 2(a) or 2(b), as applicable, if such indemnity were enforceable under applicable law. No Indemnitee shall be entitled to contribution from Holding or the Company with respect to any Obligation covered by the indemnity specifically provided for in Section 2(b) in the event that such Indemnitee is finally determined to be guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) in connection with such Obligation and Holding and the Company are not guilty of such fraudulent misrepresentation. 4. Indemnification Procedures. -------------------------- (a) Whenever any Indemnitee shall have actual knowledge of the reasonable likelihood of the assertion of a Claim, CD&R (acting on its own behalf or, if requested by any such Indemnitee other than itself, on behalf of such Indemnitee) or such Indemnitee shall notify Holding or the Company, as the case may be, in writing of the Claim (the "Notice of Claim") with reasonable promptness after such Indemnitee has such knowledge relating to such Claim and has notified CD&R thereof. The Notice of Claim shall specify all material facts known to CD&R (or if given by such Indemnitee, such Indemnitee) that give rise to such Claim and the monetary amount or an estimate of the monetary amount of the Obligation involved if CD&R (or if given by such Indemnitee, such Indemnitee) has knowledge of such amount or a reasonable basis for making such an estimate. The failure to give such Notice of Claim shall not relieve Holding and the Company of their respective indemnification obligations under this Agreement except to the extent that such omission results in a failure of actual notice to them and they are materially injured as a result of the failure to give such Notice of Claim. Holding and the Company shall, at their expense, undertake the defense of such Claim with attorneys of their own choosing satisfactory in all re- 10

spects to CD&R. CD&R may participate in such defense with counsel of CD&R's choosing at the expense of Holding and the Company. In the event that none of Holding and the Company undertakes the defense of the Claim within a reasonable time after CD&R has given the Notice of Claim, CD&R may, at the expense of Holding and the Company and after giving notice to Holding and the Company of such action, undertake the defense of the Claim and compromise or settle the Claim, all for the account of and at the risk of Holding and the Company. In the defense of any Claim, Holding and the Company shall not, except with the consent of CD&R, consent to entry of any judgment or enter into any settlement that includes any injunctive or other non-monetary relief, or that does not include as an unconditional term thereof the giving by the person or persons asserting such Claim to each Indemnitee of a release from all liability with respect to such Claim. In each case, CD&R and each other Indemnitee seeking indemnification hereunder will cooperate with Holding and the Company, so long as Holding and the Company are conducting the defense of the Claim, in the preparation for and the prosecution of the defense of such Claim, including making available evidence within the control of CD&R or such Indemnitee, as the case may be, and persons needed as witnesses who are employed by CD&R or such Indemnitee, as the case may be, in each case as reasonably needed for such defense and at cost, which cost, to the extent reasonably incurred, shall be paid by Holding and the Company. (b) Holding and the Company hereby agree to advance costs and expenses, including attorney's fees, incurred by CD&R (acting on its own behalf or, if requested by any such Indemnitee other than itself, on behalf of such Indemnitee) or any Indemnitee in defending any Claim in advance of the final disposition of such Claim upon receipt of an undertaking by or on behalf of CD&R or such Indemnitee to repay amounts so advanced if it shall ultimately be determined that CD&R or such Indemnitee is not entitled to 11

be indemnified by Holding and the Company as authorized by this Agreement. (c) CD&R shall notify Holding and the Company in writing of the amount of any Claim actually paid by CD&R (the "Notice of Payment"). The amount of any Claim actually paid by CD&R shall bear simple interest at the rate equal to the prime rate most recently set forth in The Wall Street Journal as of the date of ----------------------- such payment plus 2% per annum, from the date Holding or the Company receives the Notice of Payment to the date on which Holding or the Company shall repay the amount of such Claim plus interest thereon to CD&R. 5. Certain Covenants. Holding agrees to cause the Company to ----------------- perform its obligations under this Agreement. The rights of each Indemnitee to be indemnified under any other agreement, document, certificate or instrument or applicable law are independent of and in addition to any rights of such Indemnitee to be indemnified under this Agreement. The rights of each Indemnitee and the obligations of Holding and the Company hereunder shall remain in full force and effect regardless of any investigation made by or on behalf of such Indemnitee. Each of Holding and the Company shall maintain the State of Delaware as its state of incorporation and shall implement and maintain in full force and effect any and all corporate charter and by-law provisions that may be necessary or appropriate to enable it to carry out its obligations hereunder to the fullest extent permitted by Delaware corporate law, including without limitation a provision of its certificate of incorporation eliminating liability of a director for breach of fiduciary duty to the fullest extent permitted by Section 102(b)(7) (or any successor section thereto) of the General Corporation Law of the State of Delaware, as it may be amended from time to time. 12

The Term shall commence on the Commencement Date (as defined in the Schedule of Lease Terms) and end at 5:00 o'clock p.m. on the Expiration Date (as defined in the Schedule of Lease Terms), unless sooner terminated or extended as may be hereinafter provided. If Landlord fails i) to tender possession of the Premises on or before the Commencement Date, or ii) to timely substantially complete the work to be performed by Landlord pursuant to subparagraph (a) of the Work Agreement ("Landlord's Work"), for any reason other than an omission, delay or default caused by Tenant or Tenant's agents, then the Abatement Period (as defined in Paragraph 46 hereof) and the Term shall be extended on a day-by- day basis for each day that Landlord does not so tender possession of the Premises or timely substantially complete Landlord's Work. Tenant hereby accepts such abatement and extension of the Term in full settlement of any and all claims Tenant may have against Landlord arising from Landlord's failure to tender possession on the Commencement Date or to timely substantially complete Landlord's Work. Additionally, such day-for-day extension of the Abatement Period and Term shall apply for each day beyond September 1, 1995, but in no event beyond September 30, 1995, that Tenant has been unable to substantially complete the Tenant Improvements (as defined in the Work Agreement). Notwithstanding the foregoing, in the event that the Landlord fails to tender possession of the Premises to Tenant, with Landlord's Work substantially completed, on or before October 1, 1995, for any reason other than an omission, delay or default caused by i) Tenant or Tenant's agents, or ii) one of the matters described in Paragraph 29 hereof, 2

Tenant shall have the right, by providing written notice to Landlord after such date but prior to the Premises becoming available for occupancy, to cancel this Lease whereupon this Lease shall become null and void and each party shall be relieved of any further liability to the other. For purposes hereof, the timely substantial completion of Landlord's Work shall be determined in accordance with a schedule to be agreed upon by Landlord and Tenant promptly following execution hereof by both parties. Tenant, by its taking possession of the Premises for purposes of occupying the same for use as a business office [(but not, for purposes of performing the Tenant Improvements (as defined in the Work Agreement)], thereby acknowledges that it has inspected the Premises and any improvements made pursuant to the Work Agreement described in Paragraph 5 hereof and thereby accepts the Premises and any such improvements in their then present condition and as suited for the use intended by Tenant, subject to the repair by Landlord of any latent defects in Landlord's Work. COMPLETION OF IMPROVEMENTS -------------------------- 5. Contemporaneously with the execution of this Lease, Landlord and Tenant have entered into an agreement setting forth the improvements to be made to the Premises (the "Work Agreement"), attached hereto as Exhibit B and incorporated by reference herein. Title to the improvements shall vest in the Landlord immediately upon installation on the Premises. RENT ---- 6. Tenant shall pay to Landlord the Total Minimum Rent (as defined in the Schedule of Lease Terms). The Total Minimum Rent shall be paid in the monthly installments set forth on the Schedule of Lease Terms, each such monthly installment being payable on or before the first business day of each calendar month in advance and without demand, counterclaim (unless Tenant would lose its legal right to bring such counterclaim against Landlord as a result of making such rental payment) or offset, beginning on the Commencement Date and continuing until the Expiration Date. In the event the Commencement Date is a day other than the first business day of a calendar month, Tenant shall pay to Landlord, on or before the Commencement Date, a pro rata portion of the monthly installment of Total Minimum Rent to be based on the number of days remaining in such partial month after the Commencement Date. 3

Tenant shall also pay to Landlord, in addition to the Total Minimum Rent, in monthly installments, each such monthly installment being payable on or before the first business day of each calendar month, any and all sums of money, charges or other amounts required to be paid by Tenant to Landlord or to another person under this Lease, including, but not limited to, the amounts payable pursuant to Paragraph 8 of this Lease (collectively, "Additional Rent") (the Total Minimum Rent, together with all Additional Rent, being collectively defined as "Rent"). Non-payment of Additional Rent when due shall, at Landlord's option, constitute a default under this Lease to the same extent, and shall entitle the Landlord to the same remedies, as non-payment of Total Minimum Rent. All payments of Rent shall be mailed to the address set forth in the Schedule of Lease Terms, or to such other address as Landlord from time to time shall designate by written notice to Tenant. SECURITY DEPOSIT ---------------- 7. INTENTIONALLY OMITTED. ADDITIONAL RENT --------------- 8. During each calendar year or portion thereof included in the Term, Tenant shall pay to Landlord as Additional Rent Tenant's Proportionate Share of any increase in the following items over (i) the amount paid or accrued by Landlord for such items in the Base Year, plus (ii) for calendar years after 1996, the amount of the 1996 Additional Rent Abatement (as defined in subparagraph 46(b) hereof), if any. (1) Operating Expenses (as defined in subparagraph (b) hereof); and (2) Taxes (as defined in subparagraph (c) hereof). Commencing on January 1, 1996, Landlord and Tenant agree that Tenant shall pay monthly in advance, during the Term on the same day that Rent is paid, an amount equal to one-twelfth of Landlord's estimate of the Operating Expenses and Taxes for such following calendar year. Landlord shall make an estimate of the Operating Expenses and Taxes and notify the Tenant. 4

On or before May 1, 1997 and thereafter on or before May 1 of each year of the Term, Landlord shall provide Tenant a statement setting forth the actual Operating Expenses and Taxes for the preceding calendar year ("Operating Expense Statement") and a proposed operating budget for such matters for the current calendar year. The Operating Expense Statement shall be certified as true and accurate by Landlord and shall be accompanied by a breakdown of Operating Expenses and Taxes with such supporting detail as shall reasonably be requested in writing by Tenant. Within 30 days after delivery of such statement to Tenant, an adjustment shall thereupon be made between Landlord and Tenant to reflect any difference between Tenant's payment hereunder and the actual Operating Expenses and Taxes for the preceding calendar year and payment shall be made in accordance with the last sentence of this grammatical paragraph. Failure of Landlord to provide such estimates and statements on a timely basis shall not in any way constitute a waiver of Landlord's entitlement to receive such payments, except that Tenant shall not be required to make any payments of Operating Expenses and Taxes requested by Landlord pursuant to a requested adjustment if Landlord has not substantially complied with its obligations pursuant to this grammatical paragraph on or before July 31 of the year in which such adjustment is requested. The foregoing shall not relieve Tenant of its obligation to pay Total Minimum Rent or any portion of Additional Rent, except the portion of Additional Rent that may be requested pursuant to an adjustment request made by Landlord in the year in which Landlord has substantially failed to fulfill its obligations hereunder in accordance with the provisions of this grammatical paragraph. In no event, however, shall the monthly rent paid by Tenant be less than the Rent due pursuant to Paragraph 6 of this Lease and Paragraph 4 of the Schedule of Lease Terms. In the event that the Operating Expense Statement discloses that the Additional Rent paid by Tenant as Tenant's Proportionate Share of Operating Expenses and Taxes is greater or less than the amount actually incurred, the appropriate party shall reimburse the other for such amount within thirty (30) days after the receipt of such statement. The Operating Expenses and Taxes due under the terms and conditions of this Lease shall be payable by Tenant without any setoff or deduction. If the Building is less than 95% occupied during 1995 or any calendar year thereafter during the Term, Landlord shall adjust the Operating Expenses (including any management fees) for 1995 or such following calendar year on the basis of a 95% occupancy rate of all rentable area in the Building, for the purposes for which such areas have been constructed, without regard to any 5

abatements, curtailments or reductions in rent reserved under any lease or any portion of the Building. For purposes of this Paragraph 8, the following terms shall have the following meanings: (a) "Base Year" shall mean the year set forth as the Base Year on the Schedule of Lease Terms. (b) "Operating Expenses" shall mean all expenses, costs and disbursements of every kind and nature which Landlord shall pay or become obligated to pay because of, or in connection with, the management and operation of the Building and the land upon which it is situated (the "Land"), allocable in the reasonable discretion of Landlord to the office premises of the Building, including but not limited to: (1) Wages and salaries of all employees equal to or below the level of Building Manager engaged in operation and maintenance or security of the Building, including taxes, insurance and benefits related thereto; (2) All supplies and materials used in the operation and maintenance of the Building; (3) Cost of all utilities for the Building, including the cost of water and power, heating, lighting, air conditioning and ventilating for the Building, all at Landlord's cost for the same; (4) Cost of all maintenance and service agreements for the Building and the equipment therein, including alarm service, window cleaning, elevator maintenance and janitorial service; (5) Cost of all insurance relating to the Building which Landlord is required to maintain hereunder or which Landlord reasonably deems is prudent to maintain; (6) Cost of repairs and general maintenance (excluding repairs and general maintenance paid by proceeds of insurance or by Tenant or other third parties, and alterations attributable solely to tenants of the Building other than Tenant); 6

(7) Subject to the items specifically excluded below, the cost of any capital improvements which are intended to reduce Operating Expenses, which cost, together with interest on the unamortized balance at the prime rate of interest as announced from time to time by Mellon Bank, N.A. (the "Prime Rate") or such higher rate as may have been reasonably paid by Landlord on funds borrowed for the purpose of constructing such capital improvements, shall be amortized over the useful life or economic life thereof as shall be determined in accordance with generally accepted accounting standards consistently applied; (8) Any common area and other costs allocable to the office premises of the Building payable to the Pittsburgh History and Landmarks Foundation (the "Foundation") as provided in the Reciprocal Easement and Operating Agreement in effect between Landlord and the Foundation dated May 19, 1981; (9) A management fee for the current or any future manager of the Building (the "Manager"), but not in excess of 4% of the annual gross rentals for the Building, excluding leasing or brokerage fees; (10) Such other costs and expenses as would be construed as operating expenses by a reasonably prudent owner or operator of a first- class building in the City of Pittsburgh. Anything in this Lease to the contrary notwithstanding, there shall be excluded from Operating Expenses the following items, all determined in accordance with generally accepted accounting principles: (1) Repairs or other work occasioned by fire, windstorm, other acts of God or other casualty of any insurance nature, or by the exercise of eminent domain; (2) Marketing costs, leasing commissions, brokerage fees, attorneys' fees, costs and disbursements and other expenses incurred in connection with negotiations or disputes with tenants, other occupants, or prospective tenants; (3) The costs of renovating or otherwise improving or decorating, painting or redecorating space (other than common areas) for 7

tenants or other occupants, including permit, license and inspection costs for such renovations and improvements; (4) Landlord's costs for electricity and other services that are sold to tenants and for which Landlord is entitled to a specific reimbursement by tenants as an additional charge; (5) Costs of a capital nature, including but not limited to capital improvements, capital repairs, capital equipment and capital tools, and alterations which are considered capital improvements and replacements, except depreciation for costs of capital improvements, repairs, equipment, etc. that are made or purchased for the purpose of reducing Operating Expenses or complying with Legal Requirements (as hereinafter defined); (6) Expenses in connection with services or other benefits of a type provided to another tenant which are not provided to Tenant; (7) Costs incurred due to violation by Landlord or any other tenant of the terms and conditions of any lease; (8) Amounts paid to any party, including a division or affiliate of Landlord providing materials, services, labor, or equipment to the extent that such costs exceed the competitive costs of such materials, services, labor or equipment were they provided by an unaffiliated party in any arms-length transaction; (9) Costs incurred in connection with compliance with handicap, life, fire and safety codes; (10) Costs incurred in curing a violation of environmental laws regarding the storage, use or disposal or hazardous materials or substances (as defined by applicable laws); (11) Costs of such nature as to be already included in the management fee paid by Landlord for the Building; (12) Bad debt loss, rent loss, or reserves for either of them; 8

(13) Financing costs, including points, commitment fees, broker's fees, legal fees, and mortgage interest and amortization payments; (14) Costs for sculpture, paintings or other objects of art in excess of amounts typically spent for such items in office buildings of comparable quality in the competitive area of the Building; (15) Costs, fines or penalties incurred by Landlord due to violations of any Legal Requirements; (16) Lease payments for rented equipment, the cost of which equipment would constitute a capital expenditure if the equipment were purchased, except equipment leased for the purpose of reducing Operating Expenses or complying with Legal Requirements; (17) The cost of Building lobby upgrades, upgrades to common areas of the Building, costs of reconstruction of ceilings, costs of sprinklers, HVAC or abatement of hazardous materials or any costs incurred to bring the Building into compliance with the ADA (as hereinafter defined). Landlord further agrees that since one of the purposes of the Operating Expense provision in this Lease is to allow Landlord to require Tenant to pay for the costs attributable to its Premises, Landlord agrees that (i) Landlord will not collect or be entitled to collect Operating Expenses from all of its tenants in an amount which is in excess of 100 percent of the Operating Expenses actually paid by Landlord in connection with the operation of the Building, and (ii) Landlord shall make no profit from the collection of Operating Expenses from tenants. Taking into account the different Operating Expenses for the Building tenants, if for any calendar year commencing with 1996, the total increases charged to the Building tenants exceeds 100% of the actual increase in expenses paid by Landlord over the Operating Expenses for the Base Year, then Tenant's Proportionate Share of the amount in excess of 100 percent shall be returned to the Tenant as a credit against monthly Rent paid hereunder. (c) "Taxes" shall mean all federal, state and local governmental taxes, assessments, and charges (including transit or transit district taxes or assessments) of every kind or nature, whether general, special, ordinary or extraordinary, which Landlord shall pay or become obligated to pay 9

because of or in connection with the ownership, leasing, management, control, occupancy or operation of the Building or the Land (including without limitation all real estate taxes attributable to the Building and the Land), allocable in the reasonable discretion of Landlord to the office premises of the Building, or any tax against Landlord on rents and/or additional rents from the Building (including without limitation the Pittsburgh Business Privilege Tax) and/or of the personal property, fixtures, machinery, equipment, systems and apparatus located therein or used in connection therewith (including any rental or similar taxes levied in lieu of or in addition to general real and/or personal property taxes) applicable to the Building. For purposes hereof, Taxes for any year shall be Taxes which are due for payment or paid in that year, rather than Taxes which are assessed or become a lien during such year. There shall be included in Taxes for any year the amount of all reasonable fees, costs and expenses (including reasonable attorney's fees) paid by Landlord during such year in seeking or obtaining any refund or reduction of Taxes. The term "real estate taxes" shall mean all taxes and assessments, including special assessments, levied, assessed or imposed at any time by any governmental authority upon or against the Land and the Building, and also any tax or assessment levied, assessed or imposed at any time by any governmental authority in connection with the receipt of income or rents from said Land and Building to the extent that same shall be in lieu of (and/or in lieu of an increase in) all or a portion of any of the aforesaid taxes or assessments upon or against the Land and Building. The term "real estate taxes" shall also include any taxes not presently in effect which may hereafter be assessed and levied by any governmental body or other authority against the Land, Building or Premises. If an assessment payable in installments is levied against the Land or Building, Taxes for any year shall include only the installment of such assessment and any interest payable or paid during such year, and the cost of any assessments shall be amortized over the useful life (determined in accordance with generally accepted accounting principals) of the improvement for which such assessment was made. Taxes shall not include any federal, state or local sales, use, franchise, capital stock, inheritance, general income, gift or estate taxes, except that if a change occurs in the method of taxation resulting in whole or in part in the substitution of any such taxes, or any other assessment, for any Taxes as above defined, such substitution taxes or assessments shall be included in Taxes. Any refund paid to Landlord with respect to Taxes for a particular year within the Term shall be 10

promptly passed along to Tenant on a pro-rata basis (equal to Tenant's Proportionate Share thereof). (d) "Tenant's Proportionate Share" shall for all purposes be deemed to be the percentage set forth on the Schedule of Lease Terms. Landlord and Tenant acknowledge that the amount of Additional Rent payable by Tenant in accordance with this Paragraph 8 could decrease from one calendar year during the Term to the next calendar year, but that in no event, however, shall any monthly installment of Rent paid by Tenant during any such year be less than that specified by Paragraph 6 of this Lease and Paragraph 4 of the Schedule of Lease Terms. Landlord agrees to maintain records of all costs reimbursable by Tenant under the terms of this Lease. All such records shall be maintained in accordance with generally accepted accounting practices and shall be retained for a period of one (1) year following the date on which such costs were charged to Tenant. Tenant shall have the right, through its representatives, to examine, copy and audit such records at all reasonable times. Each Operating Expense Statement shall be conclusive and binding upon Tenant unless, within one (1) year after the date of such Operating Expense Statement, Tenant shall notify Landlord that it disputes the correctness of Operating Expense Statement, specifying the respects in which the Operating Expense Statement is claimed to be incorrect. Pending the determination of such dispute by agreement or otherwise, Tenant shall pay Additional Rent in accordance with the applicable Operating Expense Statement, and such payment shall be without prejudice to the position of Tenant. If the dispute shall be determined in favor of Tenant, Landlord shall forthwith pay to Tenant the amount of the overpayment by Tenant of Additional Rent resulting from compliance with Landlord's Operating Expense Statement, and, if the amount of overpayment is in excess of 5% of the total Operating Expenses paid by Tenant for such year, Landlord shall also pay to Tenant interest on the amount of such overpayment from the date of overpayment by Tenant at three percent (3%) above the prevailing prime rate where the Property is located. If there is a dispute as to any Operating Expense Statement, either party may refer the matter in dispute to an independent accounting firm selected by both parties whose decision shall be binding. If the parties cannot agree upon an independent accounting firm within thirty (30) days after request by either party, then either party may seek arbitration in accordance with the rules of the American Arbitration Association. The fees and expenses of the accounting firm or the arbitrators shall be borne by the unsuccessful party. 11

LATE RENTAL PAYMENTS -------------------- 9. If Tenant fails to pay the Rent due pursuant to Paragraphs 6 and 8 hereof by the fifth day of any calendar month, or if any other Additional Rent due under and pursuant to this Lease is not paid on or before the due date thereof, then Tenant shall pay in addition to the Rent due a late charge equal to 5% of the Rent then due. Furthermore, if the Rent is not then paid within 25 days of the due date thereof, Tenant shall pay interest at the rate (the "Default Rate") equal to the lesser of the (i) highest rate permitted by law or (ii) 2% per annum above the Prime Rate expressed in terms of an annual percentage on any Rent which is not paid when due, said interest to run from the 15th day following the due date thereof until such Rent is paid. USE OF PREMISES - RULES & REGULATIONS ------------------------------------- 10. Tenant shall use and occupy the Premises solely for the purpose(s) set forth on the Schedule of Lease Terms. Tenant shall not use or occupy the Premises for any other purpose or business without the prior written consent of Landlord, which shall not be unreasonably withheld or delayed. Tenant shall observe and comply with the Rules and Regulations, initialed and attached hereto as Exhibit C and made a part hereof. All such Rules and Regulations shall apply to Tenant and its employees, agents, licensees, invitees, sub-tenants and contractors. Any material breach of the Rules and Regulations hereunder shall, at Landlord's option, constitute a default under this Lease to the same extent, and shall entitle the Landlord to the same remedies, as any other default hereunder. Without limitation of any of the other Rules and Regulations, Tenant agrees that it shall not exceed the floor load limit of the Building of 150 pounds per square foot. Landlord agrees that it shall use diligent efforts to enforce the Rules and Regulations uniformly against all tenants in the Building. ALTERATIONS AND ADDITIONS ------------------------- 11. (a) Tenant may, at its own expense, and without Landlord's prior consent, make such changes, alterations, additions or improvements to the Premises ("Alterations") and install such Tenant Property (as hereinafter defined) in the Premises as will, in the judgment of Tenant, better adapt the same for its purposes, provided that Tenant must obtain Landlord's prior written consent for any structural or mechanical alterations, which consent shall not be unreasonably withheld, delayed or qualified. 12

(b) All Alterations made by Tenant (other than Tenant's trade fixtures) shall become, upon expiration of this Lease, the property of Landlord and shall remain on the Premises, subject to the provisions of subparagraph 11(e) hereof. Not later than thirty (30) days after the expiration of the Term, Tenant shall remove all Tenant Property and repair any damage to the Premises caused by such removal, except for ordinary wear and tear. For purposes hereof, "Tenant Property" shall mean Tenant's personal property, furniture, furnishings, signs, telecommunication equipment, equipment and trade fixtures. (c) Tenant shall comply with all applicable laws, ordinances, rules, regulations (including those of Landlord) and codes arising out of Tenant's activities under this Paragraph 11. (d) Tenant shall defend, indemnify and save Landlord harmless (including reasonable attorneys' fees and other costs of defense) from any and all mechanic's liens placed on the Premises or the Building arising out of Tenant's activities under this Paragraph 11. Without limitation of the foregoing, Tenant shall not permit any mechanics' or materialmen's liens to be filed against the fee of the Premises or against Landlord's interest in the Premises by reason of work, labor, services or materials supplied or claimed to have been supplied to Tenant or anyone holding the Premises through or under Tenant, whether prior or subsequent to the Commencement Date. If any such mechanics' or materialmen's liens shall at any time be filed against the Premises as a result of any alterations, additions, improvements, repairs or installations performed by or on behalf of Tenant, and Tenant shall fail to remove same (by bonding or otherwise) within 15 days of the date Tenant receives notice of the same, it shall constitute a breach of this Lease. (e) Anything in this Lease to the contrary notwithstanding, Tenant shall not be required at any time to remove from the Premises, or restore (i) any Alterations made with Landlord's consent unless Landlord at the time it gives such consent expressly requires in writing removal or restoration of such Alterations; (ii) any of the work described on Exhibit B; or (iii) any partitions, provided these are cut off or capped in accordance with applicable codes. (f) If alterations have been made in corridors, reception rooms or toilets, or additional toilets, stairways or other facilities have been installed, or if 13

otherwise rentable area has been used for such facilities, the Tenant will, at the expiration or sooner termination of the Term, if required by the Landlord or its agent, pay for restoring the area so altered by Tenant to the form typical in the Building. (g) Tenant agrees to repair any damage to the Premises caused by, or in connection with, the removal of any articles of personal property, business or trade fixtures, alterations, improvements and installations, including, without limitation thereto, repairing the floor and patching and painting the walls where required by Landlord to Landlord's reasonable satisfaction. BUILDING SERVICES ----------------- 12. Landlord shall provide, within its standards on each item, the following services and facilities: (a) Air conditioning, ventilation and heating through the systems of the Building, Monday through Friday of each week (except legal holidays) from the hours of 7:00 A.M. to 6:00 P.M. and Saturday from 8:00 A.M. to 1:00 P.M. ("Normal Business Hours"). For purposes hereof "legal holidays" mean New Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. Landlord has the capability of providing HVAC in half-floor increments. Tenant shall give Landlord 4 hours notice in the event Tenant desires HVAC outside Normal Business Hours and Tenant shall pay Landlord its cost for the same at the then current market rate (Landlord and Tenant acknowledge and agree that said market rate on the date of execution of this Lease is $50.00 per hour per floor. In determining such market rate in the future, Landlord shall use a basis substantially identical to that used to determine the market rate on the date of execution hereof). (b) Electric current for Building standard level of illumination using standard lighting fixtures of Landlord's choice and for ordinary small business equipment and fixtures, such as, but not limited to, typewriters, pencil sharpeners, copiers, desk calculators and other standard personal and office computers connected to the Building's standard duplex electrical receptacles; and Landlord shall replace light globes and/or fluorescent tubes in the standard lighting fixtures initially installed in the Premises by Landlord. The standard consumption of electricity used in the Premises 14

shall be a total connected load (lighting and power) of 4.0 watts per square foot of any given space or room. If Tenant desires to install any electrical equipment in addition to the aforesaid or an amount of equipment which is more than an ordinary executive office amount of such equipment or if Tenant uses more than the aforesaid standard consumption of electricity, then the monthly payments of Additional Rent shall be appropriately increased to reflect the additional electric consumption caused thereby based upon an electrical survey procured by Landlord, at the expense of Tenant, provided, however, that nothing herein shall be construed to require Landlord to furnish such additional electric current. Tenant acknowledges and agrees that its computer room shall be separately metered, which shall be done at Tenant's cost and expense. Upon receiving prior written approval from Landlord, which shall not be unreasonably withheld or delayed, Tenant may install, at Tenant's cost, supplemental HVAC systems for the Premises. Tenant shall pay the actual cost for i) electrical usage for separately metered supplemental HVAC, and ii) the commercially reasonable and typical maintenance cost of such supplemental HVAC. Landlord shall be responsible for contracting for the maintenance of such HVAC system. (c) Continuous elevator service during regular business days and normal business hours, and subject to call at all other times. (d) Cleaning service as set forth on Exhibit D attached hereto and made a part hereof. (e) Security procedures and systems consistent with other first-class office buildings in the City of Pittsburgh. (f) Tenant shall be allowed, subject to the reasonable approval of Landlord, to use Tenant's standard graphics, at Tenant's sole cost and expense, at the entrance to the Premises. Throughout the Term, Tenant shall be provided with 3 lines in the Building's directory in the lobby. Landlord shall not be liable in damages or otherwise for delay or failure in furnishing any of the foregoing services or facilities, where such delay or failure is excusable pursuant to the provisions of Paragraph 29 hereof. In no event shall such delay or failure, regardless of cause, constitute an eviction of Tenant or termination of this Lease. Tenant shall be permitted to abate its Rent payments to the extent such delay or failure in furnishing the foregoing services is caused by 15

Landlord's negligence or intentional misconduct and results in a substantial portion of the Premises not being useable for their intended purposes by Tenant for five (5) consecutive days. The Rent shall abate only for the period of time beyond such five (5) day period and for that portion of the Premises that is so rendered unusable by Tenant. For all utility or other services requested by Tenant, which are not specifically included in this Paragraph 12, Tenant shall pay as Additional Rent to Landlord Landlord's established charges for such services; provided, however, that with respect to air conditioning, ventilation or heating provided to the Tenant, at its request, other than during the hours set forth above, Tenant shall pay as Additional Rent the then current market rate for the same (which shall be limited to Landlord's actual utility cost, depreciation and labor costs associated therewith). Tenant acknowledges that Landlord shall not provide telephone or telecommunication services to Tenant. Further, Tenant acknowledges that Landlord has made no representations or warranties as to the general fitness of the Building cable, including, but not limited to, telephone wires, telephone lines, telecommunications cable, riser equipment, individual pairs and all associated equipment and facilities (the "Cable"), and Landlord does not and will not warrant the uninterrupted or unimpaired transmission of messages, data or other signals. To the extent not prohibited by law, Tenant agrees that Landlord, Landlord's beneficiaries and their respective partners, affiliates, officers, agents, servants and employees shall not be liable to Tenant or other persons for any and all injury, loss or damage, including, but not limited to, lost profits and economic damages resulting from interruption or failure of the transmission of messages, data or other signals, whether such interruption or failure is due to the happening of any occurrence, event or accident in or about the Building, including the Premises, or due to any act or neglect of any person other than Landlord, including, but not limited to, Tenant or any occupant of the Building. Tenant shall not, without the prior written consent of Landlord, which shall not be unreasonably withheld, alter, modify or in any way change existing telecommunication equipment or facilities, including, but not limited to, any addition to or modification of existing wire closet conditions, or install or cause to be installed any telecommunications equipment which is in addition to that equipment present prior to the Commencement Date. At Landlord's request, Tenant shall furnish to Landlord a detailed description of any additional telecommunications equipment requested to be installed and an assessment of the impact upon the Cable and Premises due to the installation of such 16

telecommunications equipment and facilities. Tenant further agrees to indemnify Landlord for any and all damage to the Building and Premises caused by such installation of telephone equipment and facilities, and upon request of Landlord, agrees to remove any and all installed equipment and facilities upon termination of the Lease, whether by expiration of the Term or otherwise. ASSIGNMENT AND SUBLETTING ------------------------- 13. Tenant, for itself, its successors, legal representatives and assigns, expressly covenants that Tenant shall not, either voluntarily or by operation of law, assign, transfer, mortgage or otherwise encumber this Lease or sublet the Premises or permit any part thereof to be used or occupied by anyone other than Tenant or Tenant's employees, without the prior written consent of Landlord, which shall not be unreasonably withheld. Tenant may, nevertheless, assign this Lease or sublet the Premises at any time to a subsidiary or affiliated company without obtaining Landlord's consent. In the event of any such assignment or sublet to a subsidiary or affiliated company of Tenant the assignee, subtenant or surviving corporation shall be deemed the assignee of all Tenant's rights and obligations under this Lease, provided that Tenant shall promptly notify Landlord of such assignment or sublet, of the name of the new tenant and its address, and shall confirm in such notice, which shall be subscribed by the new tenant, that the new tenant shall have assumed all of Tenant's obligations hereunder and that such assignment or sublet shall not be deemed in any manner whatsoever to relieve Tenant of any of its obligations hereunder. In the event of any assignment or sublease, no such assignment or sublease shall be deemed a waiver of the requirements of Landlord's consent to any subsequent assignment or sublease, and any such consent, if given by Landlord, shall not release Tenant from its obligations under this Lease unless consented to by Landlord. In the event Tenant should desire to assign this Lease or sublet the Premises or any part hereof except as provided in the preceding paragraph, Tenant shall give Landlord written notice at least 10 business days in advance of the date on which Tenant desires to make such assignment or sublease, which notice shall specify: (a) the name, address and business of the proposed assignee or sublessee, (b) the amount and location of the space in the Premises affected, (c) the proposed effective date and duration of the subletting or assignment, and (d) the proposed rental to be paid to Tenant by such sublessee or assignee. Landlord shall then have a period of 10 days following receipt of such notice within which to notify Tenant in writing that Landlord elects either (i) to terminate this Lease as to the space so affected as of the date so specified by Tenant, in which event Tenant will 17

on that date be relieved of all future obligations to pay Rent or any other obligations arising under this Lease as to such space; or (ii) to permit Tenant to assign or sublet such space, in which event if the proposed rental rate between Tenant and sublessee is greater than the rental rate of the Lease, then 50% of such excess rental, after deduction of reasonable leasing costs, costs of tenant improvements incurred for the sublessee and commissions actually paid by Tenant in connection with such subletting, shall be deemed Additional Rent owed by Tenant to Landlord under this Lease, and the amount of such excess, including any subsequent increases due to escalation or otherwise, shall be paid by Tenant to Landlord in the same manner that Tenant pays the Rent hereunder and in addition thereto; or (iii) provided that Landlord has a reasonable basis for objecting to the particular subtenant, to withhold consent to Tenant's assignment or subleasing such space and to continue this Lease in full force and effect as to the entire Premises. If Landlord should fail to notify Tenant in writing of such election within said 10 business day period, Landlord shall be deemed to have elected option (ii) above. In the event that Tenant lets only a portion of the Premises, Tenant shall be responsible for paying all costs and expenses incurred in connection with dividing the Premises into separate suites. INSPECTION ---------- 14. Landlord, its employees, servants and agents shall have the right to enter the Premises at all reasonable times for the purpose of examining or inspecting the Premises to see that Tenant is complying with all of its obligations hereunder, showing the same to prospective purchasers, mortgagees or tenants of the Building (Landlord shall show the Premises to prospective tenants of the Premises only during the 180 day period preceding the expiration of the Term), performing janitorial and cleaning services, and making such alterations, repairs, improvements or additions to the Premises or to the Building as Landlord may deem necessary or desirable, and Landlord shall be allowed to take all material into and upon the Premises that may be required therefor without the same constituting an eviction of Tenant in whole or in part, and the Rent reserved shall in no way abate while said alterations, repairs, improvements or additions are being made, by reason of loss or interruption of business of Tenant, or otherwise, provided that such work is diligently prosecuted to completion by Landlord in a workmanlike fashion. If representatives of Tenant shall not be present to open and permit entry into the Premises at any time when such entry by Landlord is necessary or permitted hereunder, Landlord may enter by means of a master key 18

(or forcibly in the event of an emergency) without liability to Tenant and without such entry constituting an eviction of Tenant or termination of this Lease. Landlord agrees to use reasonable efforts to notify Tenant in advance of Landlord's intention to enter the Premises in accordance with this Paragraph 14, except in emergency situations. Landlord shall use reasonable efforts to minimize interference with Tenant's business in the exercise of Landlord's rights pursuant to this Paragraph 14, and shall use reasonable efforts to give Tenant prior notice of its intention to enter the Premises in non-emergency situations, and subsequent notice respecting entries of Landlord that occur in Tenant's absence. REPAIRS ------- 15. During the Term, Landlord shall, at its sole expense, perform with reasonable diligence and promptness and in a good and workmanlike manner all maintenance, repairs and replacements reasonably deemed necessary by Landlord to (i) the structural components of the Building, including the roof, exterior walls, bearing walls, support beams, foundations, columns, exterior doors and windows and lateral support to the Building; (ii) assure watertightness of the Building, including the Premises (including caulking of the flashings) and repairs to the roof, curtain walls, windows, and skylights, if required, to assure watertightness; (iii) the plumbing, fire sprinkler, heating, ventilation and air conditioning systems and electrical lines and equipment associated therewith, including elevators; (iv) the common areas of the Building, including its lighting systems; (v) exterior improvements to the Building, including walkways, shrubbery and landscaping, if any and (vi) glass cleaning and replacements; provided, however, that Landlord shall pursue with reasonable diligence such repairs after Landlord becomes aware, or that Landlord should have become aware through the exercise of reasonable diligence or receipt of written notice from Tenant that such repair is needed. In no event shall Landlord be obligated under this Paragraph to repair any damage caused by any act, omission or negligence of Tenant or its employees, agents, invitees, licensees, subtenants or contractors. Except as Landlord is obligated for repairs as provided hereinabove, Tenant shall make, at its sole cost and expense, all repairs necessary to maintain the Premises and shall keep the Premises and the fixtures therein neat and in orderly condition. If Tenant refuses or neglects to make such repairs, or fails to diligently prosecute the same to completion, after written notice from Landlord of the need therefor, Landlord may make such repairs at the expense of Tenant and Tenant shall pay as Additional Rent Landlord's cost to make such repair. 19

Landlord shall not be liable by reason of any injury to, or interference with, Tenant's business arising from the making of any repairs, alterations, additions or improvements in or to the Premises or the Building or to any appurtenances or equipment therein. There shall be no abatement of Rent because of such repairs, alterations, additions or improvements, except as provided in Paragraph 19 hereof and except if such repairs, etc. are necessitated by Landlord's negligence or intentional misconduct and result in a substantial portion of the Premises not being usable for their intended purposes by Tenant for 5 consecutive days. The Rent shall abate only for the period of time beyond such five (5) day period and for that portion of the Premises that is so rendered unusable by Tenant. Notwithstanding any other provisions herein, Landlord shall not be liable to Tenant for any damage to Tenant's furniture, fixtures or other personalty occasioned by plumbing, electrical, gas, water, steam or other utility pipes, systems or facilities or by the bursting, stopping, leaking or running of any tank, sprinkler, washstand, water closet or pipes in or about the Premises or the Building, or for any damage to the same occasioned by water, snow or ice being upon or coming through or around the roof or any flashing, window, skylight, vent, door, or the like unless directly resulting from Landlord's negligence or intentional misconduct. Landlord shall not be liable to Tenant for any negligent act or omission of Tenant nor shall Landlord be liable to Tenant for any damage arising out of any acts or neglect of other tenants of the Building, occupants of the Building, occupants of adjacent property or the public. SURRENDER OF PREMISES --------------------- 16. Tenant shall surrender the Premises to Landlord at the expiration or sooner termination of the Term in the condition specified in Paragraph 11 hereof without notice of any kind, and Tenant waives all right to any such notice as may be in effect in Pennsylvania, including, without limitation, the Landlord and Tenant Act of 1951, as amended. The provisions of this Paragraph shall survive the expiration or sooner termination of this Lease. INDEMNIFICATION AND LIABILITY ----------------------------- 17. Each party shall defend, indemnify and save harmless the other against all claims, liabilities, losses, damages, costs and expenses (including reasonable attorneys' fees and other costs of defense) because of injury, including death, to any person, or damage or loss of any kind to any property caused by the negligence or 20

misconduct of such party, its agents, employees or contractors, or by such party's failure to perform its obligations under this Lease. INSURANCE --------- 18. (a) Landlord shall maintain, at its expense, during the Term, with solvent and responsible companies, fire insurance, with standard "all risk" coverage for the Building. Such coverage shall equal one hundred percent (100%) of the replacement cost of the Building (including, without limitation, improvements made pursuant to the Work Agreement), as determined by Landlord in its sole and absolute discretion exclusive of architectural and engineering fees, excavation, footings and foundations. (b) Landlord shall maintain, at its expense, during the Term, with solvent and responsible companies, comprehensive general liability insurance covering injuries occurring on the Property, which shall provide for a combined coverage for bodily injury and property damage in an amount not less than Three Million Dollars ($3,000,000). (c) Tenant shall maintain, at its expense, during the Term, with solvent and responsible companies, comprehensive general liability insurance for the Premises in a combined coverage for bodily injury and property damage in an amount not less than Three Million Dollars ($3,000,000). Tenant shall name Landlord, and any mortgagee of which Landlord has advised Tenant, as additional insureds under such policy. (d) Tenant shall maintain, at its expense, during the Term, with solvent and responsible companies, all risks insurance including extended coverage endorsement for such additional perils as Landlord shall reasonably require from time to time in respect of Tenant's fixtures, Tenant's furnishings, Tenant's equipment, and such other property of Tenant in the Premises as Landlord may from time to time require. The aforesaid policy or policies shall be written with insurance limits of not less than the full replacement cost thereof, on a stated amount basis, subject only to such deductibles and exclusions as Landlord may approve, which approval shall not be unreasonably withheld. (e) The policy or policies evidencing such insurance for paragraphs 18(a), (b), (c) and (d) shall provide that they may not be cancelled or amended without fifteen (15) days prior written notice being given to the party for 21

whose benefit such insurance has been obtained. Prior to the Commencement Date, each party shall submit to the other insurance certificates demonstrating the required policies are in effect. (f) Tenant shall not keep or use in or upon the Premises any article which may be prohibited by any insurance policy in force from time to time covering the Premises or the Building. If the occupancy of the Premises, the conduct of business in the Premises or any act or omission of Tenant in the Premises, causes or results in any increase in premiums for the insurance carried from time to time by Landlord with respect to the Building, Tenant shall pay to Landlord as Rent forthwith on demand the cost of any increase in premiums. (g) The parties release each other and their respective authorized representatives from any claims for damage to the Building or the Premises that are caused by or result from risks insured against under any risk or fire insurance policies carried by either of the parties. Each party to the extent possible shall obtain, for each policy of insurance, provisions permitting waiver of any claims against the other party for loss or damage within the scope of the insurance and each party to the extent permitted, for itself and its insurer, waives all such insured claims against the other party. Any liability that either party may have against the other shall be limited to the amount that exceeds the amount of insurance proceeds received by the indemnified party. DAMAGE AND DESTRUCTION ---------------------- 19. If and whenever both (i) all or 20% or more of the rentable area of the Building, or 20% or more of the rentable area of the Premises shall be damaged or destroyed by any cause or in the reasonable opinion of Landlord the Building is rendered unsafe, whether or not the Premises are affected thereby, and (ii) in Landlord's reasonable opinion the Building or the Premises cannot with the exercise of reasonable diligence be repaired, restored or rebuilt within a period of 180 days after the happening of such damage or destruction, Landlord or Tenant may terminate this Lease upon 60 days' notice given within 30 days after the happening of such damage or destruction and upon the expiration of the 60 day notice period Tenant shall surrender the Premises to Landlord and Rent shall be apportioned to the date of such termination. 22

If and whenever the Premises are damaged or destroyed by any cause and this Lease shall not have been terminated by Landlord, Landlord shall with all reasonable diligence make the repairs specified in Paragraph 15 hereof and Tenant shall with all reasonable diligence and at its sole expense make all other repairs and do all other items of work which are necessary properly to complete the Premises for use and occupancy by Tenant. All such repairs and work by Tenant shall be carried out in accordance with the requirements of Paragraph 11 hereof. If, as a result of any damage or destruction to the Premises which Landlord is obligated to repair under the provisions of Paragraph 15 hereof (including the Tenant Improvements to be made pursuant to the Work Agreement) and which is not merely an interruption of or interference with any utility, service or access, the Premises are rendered in whole or in part unfit for use and occupancy by Tenant, then during the period following the occurrence of such damage or destruction and ending upon the earlier of: (a) the date on which the repairs to the Premises which Landlord is obligated to make as aforesaid are completed sufficiently to enable Tenant to commence the repairs it is obligated to make and Tenant has had a reasonable period of time within which its repairs could have been completed with due diligence; and (b) the date on which the proceeds of any loss of rental income insurance attributable to any shortfall in Rent from the Premises is no longer paid to Landlord; Rent shall abate in the same proportion that that part of the rentable area of the Premises which is incapable of use is to the rentable area of the Premises. CONDEMNATION ------------ 20. If the whole of the Premises shall be condemned or taken either permanently or temporarily for any public or quasi-public use or purpose, under any statute or by right of eminent domain, or by private purchase in lieu thereof, then and in that event, the Term shall cease and terminate from the date of possession of the Premises by such condemning authority, and Tenant shall have no claims against Landlord for the value of any unexpired Term, and shall release unto Landlord any such claim it may have against the condemnor, except to the extent set forth in the last sentence of this Paragraph 20. In the event that 20% or more of the 23

Building or 20% or more of the rentable area of the Premises shall be so taken, Landlord may elect to terminate this Lease from the date of title vesting in such proceeding or purchase, or Landlord may elect to repair and restore, at its own expense, the portion not taken and thereafter the Rent shall be reduced proportionately (i.e. based on the ratio that the square feet of rentable area in the Premises immediately prior to such condemnation bears to the square feet of rentable area in the Premises remaining thereafter). If 20% or more of the Building or 20% or more of the rentable area of the Premises shall be so taken, Tenant may cancel and terminate this Lease effective as of the date possession of such portion condemned shall be taken by such condemning authority, provided that such option to cancel is exercised within 60 days of the receipt of notice by Tenant to the effect that such condemnation exceeds 20% of the Building or 20% of the rentable area of the Premises. In the event the Premises or any part thereof shall be permanently taken or condemned or transferred by agreement in lieu of condemnation for any public or quasi-public use or purpose by any competent authority, the entire compensation award therefor, both leasehold and reversion, shall belong to Landlord without any deduction therefrom for any present or future estate of Tenant, and Tenant hereby assigns to Landlord all its right, title and interest to any such award. Tenant shall execute all documents required to evidence such result. Tenant shall, however, be entitled to claim, prove and receive in such condemnation proceedings such award as may be allowed for moving expenses, stationery costs, fixtures and other equipment installed by it but only if or to the extent such award shall be in addition to the award for the Land and the Building and other improvements (or portions thereof) forming part of the Premises. SUBORDINATION AND ATTORNMENT ---------------------------- 21. Landlord represents that there currently is no mortgage encumbering the Building. Landlord is hereby vested with full power and authority to subordinate Tenant's interest hereunder to the lien of any mortgage which may hereafter be placed on the Building and to all renewals, modifications, consolidations and replacement of such mortgage. As a condition to the subordination of Tenant's interest hereunder to any future mortgage encumbering the Building, Landlord shall obtain and deliver to Tenant from any future mortgagee a written non-disturbance agreement in recordable form providing that so long as Tenant performs all of the terms, covenants and conditions of this Lease and agrees to attorn to the mortgagee or purchaser at a foreclosure sale, Tenant's rights under this Lease shall not be disturbed and shall remain in full force and effect for the 24

Term, and Tenant shall not be named or joined by the holder of any mortgage in any action or proceeding to foreclose thereunder. ESTOPPEL CERTIFICATES --------------------- 22. Tenant and Landlord shall, at any time and from time to time, within 15 days following receipt of written request from the other, execute, acknowledge and deliver to the other a written statement certifying that this Lease is in full force and effect and unmodified (or, if modified, stating the nature of such modification), certifying the date to which the rent reserved hereunder has been paid, and certifying that there are not, to such party's knowledge, any uncured defaults on the part of the other hereunder, or specifying such defaults if any are claimed. Any such statement given by Tenant may be relied upon by any prospective purchaser or mortgagee of all or any part of the Building or Land. Tenant's failure to deliver such statement within the said 15 day period shall be conclusive upon Tenant that this Lease is in full force and effect and unmodified (or, if modified, stating the nature of such modification), and that there are no uncured defaults in Landlord's performance hereunder. DEFAULT ------- 23. The occurrence of any of the following shall, at Landlord's option, constitute a material default and breach of this Lease by Tenant: (a) A failure by Tenant to pay the Rent reserved herein, or to make any other payment required to be made by Tenant hereunder, where such failure continues for 10 days after Landlord provides Tenant with written notice of such failure; (b) A failure by Tenant to observe and perform any other provisions or covenants of this Lease to be observed or performed by Tenant, where such failure continues for 30 days after receipt of written notice thereof from Landlord to Tenant, provided, however, that if the nature of the default is such that the same cannot reasonably be cured within such 30 day period, Tenant shall not be deemed to be in default if Tenant shall within such period commence such cure and thereafter diligently prosecute the same to completion; (c) The making by Tenant of any assignment for the benefit of creditors; the adjudication that Tenant is bankrupt or insolvent; the filing by or against 25

Tenant of a petition to have Tenant adjudged a bankrupt or a petition for reorganization or arrangement under any law relating to bankruptcy (unless, in the case of a petition filed against Tenant, the same is dismissed within 60 days after the filing thereof); the appointment of a trustee or receiver to take possession of substantially all of Tenant's assets located in the Premises or of Tenant's interest in this Lease (unless possession is restored to Tenant within 30 days after such appointment); or the attachment, execution or levy against, or other judicial seizure of, substantially all of Tenant's interest in this Lease (unless the same is discharged within 30 days after issuance thereof). ACCELERATED RENT ---------------- 24. In the event of any default or breach of this Lease by Tenant as set forth in Paragraph 23 hereof, the Rent reserved herein for the entire unexpired portion of the Term shall, at Landlord's option, thereupon immediately become due and payable; discounted to the then present value at the discount rate of the Federal Reserve Bank having jurisdiction over Pittsburgh, Pennsylvania in effect at the time of the default. In determining the amount of any future payments due Landlord due to increases in Taxes and Operating Expenses, Landlord may make such determination based upon the amount of Taxes and Operating Expenses paid by Tenant for the calendar year immediately prior to such default. Tenant shall be obligated for such accelerated Rent regardless of which, if any, of the remedies provided in Paragraph 25 hereof or provided by law Landlord elects to pursue. REMEDIES -------- 25. In the event of any default or breach of this Lease by Tenant as set forth in Paragraph 23 hereof, Landlord, at its option, may terminate this Lease upon and by giving written notice of termination to Tenant, or Landlord, without terminating this Lease, may at any time after such default or breach, without notice or demand additional to that provided in Paragraph 23 hereof, and without limiting Landlord in the exercise of any other right or remedy which Landlord may have by reason of such default or breach (other than the aforesaid right of termination) exercise any one or more of the remedies hereinafter provided in this Paragraph or as otherwise provided by law, all of such remedies (whether provided herein or by law) being cumulative and not exclusive: (a) Landlord may perform for the account of Tenant any defaulted term or covenant on Tenant's part to be observed or performed, and recover as 26

Rent any expenditures made and the amount of any obligations incurred in connection therewith. (b) Subject to applicable law, Landlord may enter the Premises (without thereby incurring any liability to Tenant unless Landlord is negligent and without such entry being constituted an eviction of Tenant or termination of this Lease) and take possession of the Premises at any time and from time to time to let the Premises or any part thereof for the account of Tenant, for such terms, upon such conditions and at such rental as Landlord may deem reasonable and proper. In the event of such reletting, (i) Landlord shall receive and collect the rent therefrom and shall first apply such rent against such expenses as Landlord may have incurred in recovering possession of the Premises, placing the same in good order and condition, altering or repairing (in a commercially reasonable manner) the same for reletting, and such other expenses, commissions and charges, including reasonable attorneys' fees and real estate commissions, which Landlord may have paid or incurred in connection with such repossession and reletting, and then shall apply such rent against the accelerated Rent, and (ii) Landlord may execute any lease in connection with such reletting, and the tenant of such reletting shall be under no obligation to see to the application by Landlord of any rent collected by Landlord. (c) The parties hereto hereby waive their right to require a trial (or determination of fact) by jury in any action or proceeding or counterclaim between the parties in any way connected with this Lease, the relationship of Landlord and Tenant, Tenant's use or occupancy of the Premises, and/or any claim of injury or damage. CONFESSION OF JUDGMENT AND EJECTMENT ------------------------------------ 26. INTENTIONALLY DELETED WAIVER ------ 27. The failure or delay on the part of either party to enforce or exercise at any time any of the provisions, rights or remedies in this Lease shall in no way be construed to be a waiver thereof, nor in any way to affect the validity of this Lease or any part hereof, or the right of the party to thereafter enforce each and every such provision, right or remedy. No waiver of any breach of this Lease shall be held to be a waiver of any other or subsequent breach. The receipt by 27

Landlord of Rent at a time when the Rent is in default under this Lease shall not be construed as a waiver of such default, unless the payment fully remedies the default. The receipt by Landlord of a lesser amount than the Rent due shall not be construed to be other than a payment on account of the Rent then due, nor shall any statement on Tenant's check or any letter accompanying Tenant's check be deemed an accord and satisfaction, and Landlord may accept such payment without prejudice to Landlord's right to recover the balance of the Rent due or to pursue any other remedies provided in this Lease. No act or thing done by Landlord or Landlord's agents or employees during the Term shall be deemed an acceptance of a surrender of the Premises, and no agreement to accept such a surrender shall be valid unless in writing and signed by Landlord. QUIET ENJOYMENT --------------- 28. If and so long as Tenant pays the Rent reserved hereunder and observes and performs all of the covenants, conditions and provisions on Tenant's part to be observed and performed hereunder, Tenant shall and may peaceably and quietly have, hold and enjoy the Premises for the entire Term hereof, subject nevertheless to all of the provisions of this Lease including, but not limited to, all mortgages, encumbrances and other matters and things referred to in Paragraph 20 hereof. UNAVOIDABLE DELAY ----------------- 29. In the event that either party shall be delayed or hindered in, or prevented from, the performance of any work, service or other act required under this Lease to be performed by the party and such delay or hindrance is due to strikes, lockouts, acts of God, governmental restrictions, enemy act, civil commotion, unavoidable fire or other casualty, or other causes of a like nature beyond the control of the party so delayed or hindered, then performance of such work, service, or other act shall be excused for the reasonable period of such delay and the period for the performance of such work or other act shall be extended for a period equivalent to the period of such delay. In no event shall such delay constitute a termination of this Lease. The provisions of this Paragraph shall not operate to excuse Tenant from the prompt payment of Rent. SUCCESSORS AND MULTIPLE PARTIES ------------------------------- 30. The respective rights and obligations provided in this Lease shall bind and shall inure to the benefit of the parties hereto, their legal representatives, heirs, successors and permitted assigns; provided, however, that no rights shall inure to 28

the benefit of any successor of Tenant unless Landlord's written consent (which consent shall not be unreasonably withheld or delayed) for the transfer to such successor has first been obtained as provided in Paragraph 13 hereof. If at anytime the Tenant shall include more than one person or entity, the obligations of all such persons or, entities shall be joint and several. In the event that this Lease is executed by any partner on behalf of a partnership, this Lease shall be a binding obligation upon all partners of such partnership. GOVERNING LAW ------------- 31. This Lease shall be construed, governed and enforced in accordance with the laws of the Commonwealth of Pennsylvania, without giving effect to the principles of conflicts of laws in effect in the Commonwealth of Pennsylvania. Landlord and Tenant consent to the jurisdiction and venue of the state and if permissible under federal law, federal courts situated in Allegheny County, Pennsylvania. SEPARABILITY ------------ 32. If any provision of this Lease shall be held to be invalid, void or unenforceable, the remaining provisions hereof shall in no way be affected or impaired and such remaining provisions shall remain in full force and effect. CAPTIONS -------- 33. Marginal captions, titles of exhibits and riders to this Lease, are for convenience and reference only and are in no way to be construed as defining, limiting or modifying the scope or intent of the various provisions of this Lease. GENDER ------ 34. As used in this Lease, the word "person" shall mean and include, where appropriate, an individual, corporation, partnership or other entity; the plural shall be substituted for the singular, and the singular for the plural, where appropriate; and words of any gender shall mean to include any other gender. NOTICES ------- 35. Any bill, statement, notice or communication required or permitted hereunder shall be deemed sufficiently given if sent by certified mail, or by hand delivery or 29

telecopy, with confirmation in writing sent by certified mail, addressed as follows: To Landlord: Commerce Court Property Holding Trust c/o Management Office Commerce Court Building Four Station Square, Suite 760 Pittsburgh, Pennsylvania 15219 Facsimile No. (412) 642-6617 To Tenant: At address set forth in Paragraph 1 of Schedule of Lease Terms or addressed to Tenant at the Premises after the Commencement Date Facsimile No. (412) 642-5095 Either party may change its address by written notice so given to the other. Notice shall be deemed given when mailed, except that a notice of change of address shall be deemed effective when received. BROKERS ------- 36. Tenant represents and warrants that in this transaction it has dealt with no real estate broker other than the brokers identified in the Schedule of Lease Terms, and that no one has or will represent it in this transaction other than aforesaid. LEASE NOT AN OFFER ------------------ 37. The submission of this Lease to Tenant should not be construed as an offer, nor shall the Tenant have any rights with respect thereto unless and until Landlord shall execute a copy of this Lease and deliver the same to Tenant. RENT CONTROL ------------ 38. INTENTIONALLY DELETED LANDLORD'S EXCULPATORY ---------------------- 39. Anything contained in the foregoing to the contrary notwithstanding, Tenant agrees that it shall look solely to the estate and property of the Landlord in the Land and Building of which the Premises form a part, for the collection of any judgment (or other judicial process) requiring the payment of money by Landlord, in the event of any default or breach by Landlord with respect to any of 30

the terms, covenants and conditions of this Lease to be observed and/or performed by Landlord, and no other property or assets of Landlord shall become subject to levy, execution, attachment or other enforcement procedures for the satisfaction of Tenant's remedies. If the Land and Building of which the Premises form a part are transferred or conveyed, Landlord shall be relieved of all covenants and obligations under this Lease thereafter accruing and Tenant shall look to such transferee thereafter. RELOCATION OF TENANT -------------------- 40. INTENTIONALLY DELETED COMPLIANCE WITH LAWS -------------------- 41. Tenant shall, at its expense, comply with all laws, orders, ordinances, regulations and rules of all governmental authorities having jurisdiction and the Insurance Advisory organization (collectively, "Legal Requirements") with respect to the particular manner in which Tenant shall use or occupy the Premises, as opposed to office use generally. Tenant shall give Landlord prompt notice of any violation or recommendation of change of which it shall have received notice. Tenant shall not do or permit to be done any act or thing which will invalidate or be in conflict with any certificate of occupancy in effect for the Premises. Landlord certifies to Tenant that to the best of Landlord's knowledge, the public or common areas of the Building comply with the Americans With Disabilities Act of 1990 (the "ADA"). Landlord agrees that it shall be responsible for any portions of the public or common areas of the Building that do not comply with all Legal Requirements (including the ADA). Tenant hereby accepts responsibility for the compliance of the Premises with the ADA from and after the Commencement Date. EXHIBITS -------- 42. Attached to this Lease and made part hereof, and initialed on behalf of both parties simultaneously with the execution of this Lease are Exhibits A to D, inclusive, and the Schedule of Lease Terms. 31

MODIFICATIONS ------------- 43. This Lease, including the Exhibits and the Schedule of Lease Terms, contains all the agreements, conditions, understandings, representations and warranties made between the parties hereto with respect to the subject matter hereof and may not be modified orally or in any manner other than by an agreement in writing signed by both parties hereto or their respective successors in interest. HOLDOVER BY TENANT ------------------ 44. In the event Tenant lawfully remains in possession of the Premises after the expiration of the Term or any renewal thereof, and without the execution of a new lease, Tenant, at the sole option of the Landlord, shall be deemed to be occupying the Premises from month-to-month; provided, however that Tenant shall continue to pay monthly installments of Total Minimum Rent as set forth on the Schedule of Lease Terms and that all the terms and conditions of this Lease shall continue for the period during which such holdover tenancy exists, and Tenant shall comply therewith. RENEWAL OPTIONS --------------- 45. (a) If this Lease shall not have been terminated pursuant to any provisions hereof, and Tenant shall not have defaulted hereunder beyond any applicable cure period, then Tenant may, at Tenant's option, extend the Term for two additional successive terms of five (5) years each (an "Option Term" or the "Option Terms"). Tenant must exercise its options to extend this Lease by giving Landlord written notice thereof (the "Renewal Notice") at least 240 days prior to (a) the Expiration Date (in the case of the exercise of the first Option Term), and (b) the expiration of the first Option Term (in the case of the exercise of the second Option Term). Upon the giving by Tenant to Landlord of the Renewal Notice with respect to a particular Option Term and compliance by Tenant with the provisions of this Paragraph and the failure of Tenant to exercise its rights with respect to a particular Option Term as provided in subparagraph (b) hereof, the Term of this Lease shall be deemed to be automatically extended for such Option Term upon all of the covenants, agreements, terms, provisions, and conditions set forth in this Lease, except that the Total Minimum Rent for the Premises set forth in Paragraph 4 of the Schedule of Lease Terms shall be 95% of the then prevailing rate per annum for comparable space in the Building for 32

renewals with a five-year term. Landlord agrees to give Tenant written notice (the "Rental Rate Notice") of such prevailing rate per annum (as determined by Landlord in good faith) for a particular Option Term not less than 60 days after Landlord receives the Renewal Notice for such Option Term. (b) Notwithstanding the provisions of subparagraph (a) hereof, Tenant shall have the right to revoke its exercise of an extension of this Lease for a particular Option Term within thirty (30) days of its receipt of the Rental Rate Notice for such Option Term. (c) During the Option Terms, Tenant shall continue to pay Additional Rent. The Base Year during the first Option Term shall be the Calendar Year 2002, and during the second Option Term, the Calendar Year 2007. (d) Tenant may not renew the Lease for the second of the Option Terms unless Tenant has elected to renew the Lease for the first Option Term, and has not exercised its rights pursuant to subparagraph (b) hereof with respect to the first Option Term. ABATEMENT --------- 46. (a) Notwithstanding anything to the contrary in Paragraph 4 of the Schedule of Lease Terms, monthly installments of Total Minimum Rent shall be abated for the following months only: September through December 1995, plus any period prior to September 1995 that Tenant may occupy the Premises (the "Abatement Period"). The Abatement Period shall be extended day for day for each day that the Premises are not ready for occupancy by Tenant solely by reason of Landlord's failure to perform its obligations under the Work Agreement. If Tenant shall default hereunder and fail to cure said default within any applicable grace period, while the Abatement Period is in effect, the Abatement Period shall thereupon terminate and Tenant shall commence paying monthly installments of Total Minimum Rent hereunder (without limiting Landlord's remedies hereunder, at law, in equity or otherwise). In addition, if Tenant shall default hereunder and fail to cure said default within any applicable grace period, Tenant shall upon demand pay Landlord the amount of Total Minimum Rent theretofore abated, multiplied by a fraction, the numerator of which is the number of months then remaining in the Term at the time of the default and the denominator of which is the total number of months 33

in the Term (without limiting Landlord's remedies hereunder, at law, in equity or otherwise). (b) Tenant shall not be responsible for paying for Additional Rent attributable to increases in Operating Expenses and Taxes in the 1996 calendar year over the amount of such items in the Base Year to the extent (but only to the extent) that such increases exceed 5% of the amount of the Operating Expenses and Taxes in the Base Year i.e., if such increases in the 1996 Calendar Year exceed 5% of the Operating Expenses and Taxes in the Base Year, the Tenant shall be responsible for paying such 5% increase for the 1996 Calendar Year, but not in excess of such amount. The foregoing limitation shall apply to the 1996 Calendar Year only. (The dollar amount of Additional Rent for which Tenant is relieved of responsibility for paying in 1996 pursuant to this subparagraph 46(b) is herein referred to as the "1996 Additional Rent Abatement"). MOVE-IN AND MOVING ALLOWANCE ---------------------------- 47. When Tenant takes occupancy of the Premises and executes and delivers to Landlord an estoppel certificate in accordance with Paragraph 22 hereof, Landlord, within 30 days of the later to occur of such events, shall provide Tenant with an allowance for the costs and expenses of moving which shall be a sum that is equal to the number of rentable square feet in the Premises multiplied by $2.00 per rentable square foot (i.e. $107,008). Any portion of such $107,008 allowance that is not used by Tenant as a moving allowance may be added to the design allowance to be provided to Tenant in accordance with Paragraph 48 hereof. DESIGN ALLOWANCE ---------------- 48. When Tenant executes and delivers the Lease to Landlord and submits written invoices to Landlord and such other backup information as Landlord may reasonably request, Landlord shall provide Tenant with an allowance for the cost and expense of the preparation of Tenant's plans, construction drawings and engineering drawings which shall be a sum that is equal to the number of rentable square feet in the Premises multiplied by $2.25 per rentable square foot (i.e. $120,384). Tenant's architect will be responsible for stamping Tenant's final working drawings and construction documents. 34

PARKING SPACES -------------- 49. Pursuant to that certain Reciprocal Easement and Operating Agreement by and between Pittsburgh History and Landmarks Foundation and Commerce Court Associates dated May 19, 1981, as amended, Landlord has allocated to it a certain number of parking spaces located either in the parking garage or on surface lots related to the Building. Although allocated, these parking spaces must be rented from Pittsburgh History Landmarks Foundation directly by employees of Tenant. The parking spaces are and shall be subject to certain rules and regulations which Pittsburgh History & Landmarks Foundation shall promulgate from time to time. SATELLITE TERMINAL ------------------ 50. Tenant shall be permitted to install as its personal property, at its sole cost and expense, a satellite dish, microwave antenna and other related equipment (collectively, the "Terminal") on the roof of the Building for its exclusive use in a location mutually acceptable to Landlord and Tenant, so long as the Terminal complies with any and all applicable laws, rules and regulations, including, without limitation, structural standards and safety requirements of the Building. The method of installation shall be acceptable to Landlord, and Tenant shall be responsible for, and procure at its sole cost and expense, any permits or zoning variances necessary for the installation and operation of said Terminal. Landlord shall cooperate with Tenant, at Tenant's sole cost and expense, in the procurement of necessary permits or zoning variances and shall execute all documents reasonably required to obtain necessary permits or zoning variances. At the end of the Term (as extended or renewed, if applicable) Tenant, if directed to do so by Landlord, shall remove the Terminal and any and all of the necessary wiring and equipment concurrent therewith, and shall restore the portion of the roof which may have been damaged by removal of the Terminal to the condition which existed prior to the installation, normal wear and tear excepted. In the event Landlord contemplates roof repairs or requires access which requires temporary removal or relocation of the Terminal, or which may result in an interruption in Tenant's telecommunication services, Landlord shall formally notify Tenant at least thirty (30) business days prior to such contemplated work in order to allow Tenant to make other arrangements for such services. The cost of removal and reinstallation of the Terminal shall be borne by Tenant. Tenant or its agents or representatives shall, at all times during business hours, with advance notice to Landlord and with a building engineer or security guard 35

providing access, be permitted access to the roof, common equipment rooms, common telephone rooms and condensers for purposes of examination and repair of the Terminal and any wiring or equipment incident thereto. Tenant acknowledges and agrees that Tenant's access to the roof is restricted due to other tenant equipment and services. Tenant shall not be required to pay rent for roof space for the Terminal, provided, however, Tenant shall pay and be fully responsible for, inter alia, all costs related to any and all utilities used by Tenant in connection with the Terminal, any and all construction costs associated with the Terminal and any necessary insurance which may be required. Tenant agrees to carry such insurance on the Terminal as shall reasonably be requested by Landlord. HAZARDOUS MATERIALS ------------------- 51. (a) Landlord certifies that to the best of its knowledge, there are no hazardous substances located in or on the Premises and that there has been no violation of any law governing hazardous substances with respect to the Premises or the Building. Because of the inability to properly access the soil beneath the Building ("subbasement soils"), Landlord has been unable to conduct proper studies of the presence or absence of hazardous substances in the subbasement soil. Tests of the shallow subbasement soils indicate levels of lead higher than typical background levels, probably as a result of the existence of a railroad line on the site prior to the original construction of the Building (circa 1900). Because of the lack of access to the soils beneath the Building, which are essentially encapsulated (and the fact that the lead levels appear to be consistent with those found on comparable properties constructed on former railroad or industrial sites), Landlord believes that if such substances do exist in the subbasement soils, they present no threat whatsoever to tenants or occupants of the Building or others. (b) Tenant agrees to comply with all applicable environmental laws, rules and regulations insofar as they pertain solely to the particular manner in which Tenant shall use the Premises. (c) Tenant shall not generate, store, transport, treat, dispose of or use on the Premises hazardous or toxic substances or wastes as defined under any 36

applicable federal, state, county, or local law or regulation ("Hazardous Substances"), except that Tenant's use on the Premises of cleaning supplies, copying fluids, other office and maintenance supplies and other substances normally and customarily used by tenants of space similar to the Premises shall not be deemed a violation of this Paragraph 51(c). (d) Each of Landlord and Tenant agrees to indemnify, defend and save harmless the other from any breach of the indemnifying party's certifications, duties, or obligations under this Paragraph 51. RIGHT OF FIRST OFFER -------------------- 52. (a) Subject to the provisions of Subparagraph 52(b) hereof, during the Term, or any extension thereof, Tenant shall have a right of first offer, as herein specified, to lease all space on the seventh (7th) floor of the Building not contained in the Premises as of the date hereof (the "Right of First Refusal Space"). If, during such specified period (and subject to Subparagraph 52(b) hereof) Landlord desires to lease all or any portion of the Right of First Refusal Space, Landlord will provide Tenant with a written notice specifying the date of availability and the market terms for the Right of First Refusal Space. Tenant will respond to Landlord in writing within ten (10) days of the Landlord's notice if it elects to lease the Right of First Refusal Space. The terms and provisions for the Right of First Refusal Space shall be the same as set forth in this Lease except that the Total Minimum Rent for the Right of First Refusal Space shall be equal to the Total Minimum Rent that Tenant is then paying (on a per square foot basis) for the Premises. Landlord shall provide improvements to and improvement allowances for the Right of First Refusal Space consistent with those provided pursuant to the Work Agreement, prorated, however, based on the amount of time that will be remaining in the Term when the Right of First Refusal Space becomes available for occupancy by Tenant as compared to the original length of the Term (i.e. - 84 months). Tenant shall pay Additional Rent for the Right of First Refusal Space on a basis substantially identical to that for which Tenant is responsible for paying for the Premises in accordance with this Lease at such time. If Tenant fails to notify Landlord within such ten (10) day period of Tenant's exercise of its right of first offer, Tenant shall be, deemed to have waived its right of first offer and Landlord shall be free to lease the Right of First Refusal Space to a third party pursuant to the terms and conditions of the offer, or, in the event that a particular third party does not lease the space 37

in question, to subsequent third parties. The foregoing shall not relieve Landlord from its obligation to offer any of the Right of First Refusal Space to Tenant that previously has not been offered to Tenant. (b) Landlord's obligations and Tenant's rights pursuant to Subparagraph 52(a) hereof shall be subject to the rights for certain portions of the Right of First Refusal Space currently held by UNUM Life Insurance Company of America ("UNUM"). Without limitation of the foregoing, Landlord shall have no obligation to offer or lease portions of the Right of First Refusal Space to Tenant and Tenant shall have no rights with respect to such portions thereto, if such portions of the Right of First Refusal Space are offered and leased to UNUM pursuant to UNUM's option to renew or option to expand as contained in UNUM's existing lease. Landlord agrees that it shall provide UNUM with no extension or renewal rights beyond those contained in UNUM's existing lease, without first offering the particular space to Tenant in accordance with Subparagraph 52(a) hereof. OPTION SPACE ------------ 53. Tenant shall have the option, as hereinafter provided, to lease 6,865 square feet of space on the 6th floor of the Building as identified on Exhibit "E" attached hereto and made a part hereof (the "Option Space"). Tenant must exercise its rights with respect to the Option Space by providing Landlord written notice thereof within 10 business days of the execution hereof by Tenant. The Option Space shall be leased upon the same terms and conditions as those set forth herein for the Premises, except that the timing for completion of the Landlord's Work in the Option Space shall be as agreed to by Landlord and Tenant following the exercise by Tenant of its rights with respect to the Option Space, and the rentable area of the Premises, the Rent, Tenant's Proportionate Share, and the inducements to Tenant described in Paragraphs 47 and 48 hereof and in the Work Agreement shall be increased accordingly (based on the square footage of the Option Space). If Tenant elects to lease the Option Space as herein provided, Landlord and Tenant shall execute an amendment to this Lease to reflect the addition of the Option Space to the Premises and the appropriate (based on the square footage of the Option Space) increase in the Rent, Tenant's Proportionate Share, and the inducements to Tenant described in Paragraphs 47 and 48 hereof and in the Work Agreement that shall occur as a result thereof. If Tenant does not elect to lease the Option Space within 10 business days of the execution hereof by Tenant, all of Tenant's rights with respect to the Option Space shall expire and Tenant shall have no further rights with respect thereto. 38

IN WITNESS WHEREOF, Landlord and Tenant have respectively signed and sealed this Lease as of the day and year first above written.

(The plans and drawings listed as items (i) through (iv) of this Paragraph (b) are hereinafter referred to as the "Tenant Improvement Plans" and reference herein to "Tenant Improvements" shall mean all work to be done in the Premises by or on behalf of Tenant pursuant to the Tenant Improvement Plans or otherwise. Landlord hereby approves Tenant's use of Bohlin Cywinski Jackson and RCF Engineering as Consultants for the Tenant Improvements. (d) The Tenant Improvement Plans and the Tenant Improvements shall be consistent with Landlord's Building Standard Tenant Area Finishes and Materials (hereinafter the "Standards"), a copy of which is attached hereto as Schedule II; provided, however, that Tenant may deviate from the Standards for the Tenant Improvements if (i) the deviations are not of a lesser quality than the Standards; (ii) the deviations conform to and comply with all applicable governmental regulations and all necessary governmental permits and approvals have been secured by Tenant; (iii) the deviations do not require Building service beyond the level normally provided to other tenants in the Building and do not overload the floors or other structural components of the Building; and (iv) Landlord has determined in its sole discretion that the deviations are of a nature and quality consistent with other leased space in the Building. Landlord agrees that no fee will be charged for (i) reviewing the Tenant Improvement Plans; (ii) electricity used by the Tenant during the construction period and (iii) any general conditions, overhead or other fees for construction of the Premises. 3

(e) Tenant shall have the right to hire the contractors (hereinafter referred to as "Contractors"), subject to Landlord's prior approval. Upon approval by Landlord of Tenant's Improvement Plans and Tenant's Contractors, Tenant shall promptly commence with the construction of the Tenant Improvements and thereafter diligently prosecute the same to completion such that Tenant may occupy the Premises on the Commencement Date hereof. All Tenant Improvements shall be in full compliance with the Americans With Disabilities Act of 1990. (f) Tenant acknowledges Landlord's need to maintain certain control over the planning, construction and completion of the Tenant Improvements in light of Tenant's use of a third-party Contractor. Accordingly, notwithstanding any other provision of the Lease or this Work Agreement, Landlord and Tenant agree as follows: (i) All architects, engineers, contractors, plans, specifications, and drawings relating to the Tenant Improvements or to the design or construction thereof shall be subject to the prior review and approval of Landlord. (ii) Tenant's Contractors must perform in such a manner as to not cause or permit to be caused a material default or breach of any term, condition, rule or regulation of this Lease by Tenant. (iii) Tenant and Contractors shall maintain at all times during the construction of the Tenant Improvements and for the benefit of Landlord, its officers and employees, such insurance as Landlord may reasonably require including, without limitation, such worker's compensation and other similar insurance as is required under the laws of the Commonwealth of Pennsylvania or any political subdivision thereof. (iv) Tenant shall deliver or cause to be delivered to Landlord, complete copies of all contracts for the construction of the Tenant Improvements or for any portion thereof, prior to execution thereof by Tenant. Thereafter, but prior to the commencement of such construction, Tenant shall deliver to Landlord copies of executed originals of such construction contracts. (v) Tenant shall deliver or cause to be delivered to Landlord prior to the commencement of construction of any of the Tenant Improvements, (A) certificates or other evidence reasonably satisfactory to Landlord of such insurance as is required hereunder; (B) evidence that any and all governmental permits and licenses required for the construction of the Tenant Improvements 4

have been duly secured and remain in full force and effect; and (C) such other similar assurances which Landlord may reasonably require from time to time. (vi) All construction activities relating to the Tenant Improvements shall be coordinated by and subject to the reasonable overall supervision and oversight of Landlord or its agent. (vii) To the extent that Tenant pays directly, or causes to be paid, any Contractors, supplier or materialmen, Landlord may from time to time require from Tenant evidence of payment to all such parties during the course of construction of the Tenant Improvements and at the completion thereof. (viii) Landlord may, at its option, at any time and from time to time, inspect all construction upon the Premises. In the event that any said construction does not comply with the Tenant Improvement Plans, Landlord shall, within twenty four (24) hours of Landlord's inspection, notify Tenant in writing of such non-compliance, including the specifics thereof, whereupon Landlord may require the same to be removed and reconstructed to so comply. (g) During the construction period and prior to the date upon which Tenant takes possession of the Premises, (i) Landlord shall inspect the Premises and all improvements comprising the Tenant Improvements made to the Premises by Tenant to reasonably determine that they are satisfactory, except Punch List items, except for such latent defects, if any, as would not be discovered by a reasonable, diligently conducted inspection of the Premises ("Latent Defects"); and (ii) Tenant shall execute a certificate as to the confirmation of the Commencement Date and the Expiration Date of the Term. Tenant's failure to deliver the certificate within thirty (30) days after the Commencement Date shall be conclusive upon Tenant that the Commencement Date and Expiration Date shall be those dates set forth in this Lease. Landlord's failure to approve the construction of the Tenant Improvements shall not in and of itself constitute an eviction, in whole or in part, entitle Tenant to any abatement or diminution of Rent, relieve Tenant of any of its obligations under this Lease or impose any liability upon Landlord to Tenant or its agents or contractors by reason thereof. (h) In order to commence and complete all Tenant Improvements as efficiently and expeditiously as is reasonably possible, Landlord and Tenant agree to cooperate with each other with respect to the scheduling, coordination and performance of their respective work to be performed upon the Premises. 5

(i) Any portion of the Tenant Improvement Allowance that is not utilized by Tenant in accordance with this Work Agreement, at Tenant's election, may be added to the move-in and moving allowance provided to Tenant pursuant to Paragraph 47 of the Lease, or as a credit against rental obligations arising immediately after Tenant's abatement period expires as specified in Paragraph 46 of the Lease. (j) Change orders for the Tenant Improvements shall be treated by Landlord and Tenant comparable to other work to be performed by Tenant in accordance herewith. (k) Neither Landlord nor Tenant shall unreasonably withhold or delay its consent or approval to the extent its consent or approval is required under the terms of this letter. If the foregoing correctly sets forth our understanding, kindly acknowledge your approval in the space provided below for that purpose.

EXHIBITS: The following named Exhibits are attached hereto and incorporated by this reference: Exhibit A-Leased Premises, Exhibit B-Leasehold Improvements. 2. MONTHLY RENT. Lessee agrees to pay the prepaid monthly rent specified in Section 1.4 upon execution of this Lease and thereafter agrees to pay the monthly rent specified in Section 1.3, subject to any first months' prepaid rent specified in Section 1.4, commencing on the first day of the month following the rent commencement date specified in Section 1.5 and monthly thereafter during the term and the term of any extension options(s) specified in Section 1.9 which are exercised as provided in Section 7. Lessee agrees to pay the monthly rent to Lessor on the rent commencement date and thereafter in advance on the first day of each month in lawful money of the United States of America, without deduction or offset. Rent shall be payable to Lessor at 901 East Glendale Avenue, Sparks, Nevada 89431 or such other place as Lessor may from time to time designate in writing. In the event the rent commencement date is not the first day of a month, or the applicable termination date is not the last day of a mouth, a prorated monthly installment shall be paid for the fractional months during which this Lease commences or terminates, or both. 3. CPI RENT ADJUSTMENT. The base monthly rent specified in Section 1.3 shall be adjusted commencing on the initial CPI adjustment date specified in Section 1.6 and thereafter on the same day as the initial CPI adjustment date which is the number of months specified in Section 1.7 after the previous adjustment date, using the CPI adjustment formula specified in Section 3.1. 3.1. CPI ADJUSTMENT FORMULA. The numerical base for computing the CPI adjustment to the base monthly rent is the Consumer Price Index, San Francisco/Oakland Area-All Urban Consumers, All Items, published by the United States Department of Labor, Bureau of Labor Statistics ("Index"), which is published for the date closest preceding the lease commencement date specified in Section 1.8 ("Beginning Index"). If the Index published for the date closest preceding the date by which written notice of the exercise of an option to extend the term is required pursuant to Section 7 ("Extension Index") has increased over the Beginning Index, the monthly rent for the following period commencing on the commencement date of the extended term until the next commencement date of an extended term shall be established by multiplying the base monthly rent specified in Section 1.3 by a fraction, the numerator of which is the Extension Index and the denominator of which is the Beginning Index. In no case shall the adjusted base monthly rent be less than the base monthly rent, as increased pursuant to the application of this Section 3, then in effect nor shall the adjusted base monthly rent exceed the base monthly rent which Pacific Freeport Industrial Park Page 2 (Westinghouse Electric Corporation)

would be due and payable based on the assumption that the CPI increased by 4% annually, and was compounded annually (i.e. a total increase of 21.67% for each five (5) year period). 3.2. LATE PUBLICATION OF EXTENSION INDEX. [INTENTIONALLY OMITTED] 3.3. CHANGED OR DISCONTINUED INDEX. If the Index is changed so that the base year differs from that which is published for the date closest preceding the lease commencement date specified in Section 1.8, the Index shall be converted in accordance with the conversion factor published by the United States Department of Labor, Bureau of Labor Statistics. If the Index is discontinued or revised during the term, such other replacement government index or computation reasonably chosen by Lessor shall be used in order to obtain substantially the same result as would have been obtained as if the Index had not been discontinued or revised. 4. SECURITY DEPOSIT. [INTENTIONALLY OMITTED] 5. LATE PAYMENT. Lessee acknowledges that late payment by Lessee to Lessor of rent and other sums due under this Lease will cause Lessor to incur costs not contemplated by this Lease, the exact amount of which will be extremely difficult to ascertain. Such costs include, but are not limited to, processing and accounting charges. Accordingly, if any installment of rent or other sum due from Lessee shall not be received by Lessor within five (5) days after such amount shall be due, Lessee shall pay to Lessor a late charge equal to five (5%) percent of the overdue amount. The parties hereby agree that a five percent (5%) late charge represents a fair and reasonable estimate of the costs Lessor will incur by reason of the late payment by Lessee; provided, however that Lessee shall not be obligated to pay the foregoing late charge unless and until Lessee has failed to pay the rent or the other sums when due to Lessor on five (5) prior occasions and Lessor has given notice to Lessee on five (5) such occasions that the rent or other payments were not received when due. Acceptance of the five percent (5%) late charge by Lessor shall in no event constitute a waiver of Lessee's default with respect to any overdue amounts, nor prevent Lessor from exercising any of the other rights and remedies granted to Lessor under this Lease. Rent, all other sums due under this Lease and advances made by Lessor, not paid by Lessee when due, shall bear interest from time to time at the lower of (a) the Prime Rate in effect from time to time plus five percent (5%) per annum or (b) eighteen percent (18%) per annum from the due date until paid or (c) the highest rate permitted by law. Payment of such interest shall not excuse or cure any default by Lessee under this Lease. 6. LEASE TERM. The Lease Term is specified in Section 1.8, commencing on the lease commencement date specified in Section 1.8 and ending, subject to any extension options granted pursuant to Section 7, on the lease termination date specified in Section 1.8. 7. OPTION(S) TO EXTEND LEASE TERM. The Lessor hereby grants the option to extend the Lease Term upon all the terms, covenants and conditions contained in this Lease for the number of extension period(s) specified in Section 1.9 and for the period for each extension option specified in Section 1.9, in no event to extend beyond the last termination date specified in Section 1.9. The Lessee may exercise each option granted upon written notice delivered to the Lessor six (6) months prior to the applicable termination date of the then current Lease Term, provided that (a) the Lessee shall not be in default of a material obligation under this Lease beyond any applicable cure periods, and (b) the Lessee shall be in possession of the Premises for the use specified in Section 1.11. In the event that the Lessee is in default of any material obligation of the Lessee under this Lease beyond any applicable cure periods on the date the extended Lease Term is to commence, then, at the Lessor's option, the extension shall not commence and this Lease shall thereupon terminate. In the event the extended Lease Term does not commence, (except if the result of a force majeure or the default of the Lessor) whether due to the Lessee's failure to give a timely notice or otherwise, any and all options to extend shall automatically become invalid and of no further force or effect. Pacific Freeport Industrial Park Page 3 (Westinghouse Electric Corporation)

8. PARKING. Lessee shall be entitled to use the number of parking spaces specified and designated as provided in Section 1.2. Lessee agrees that vehicles of Lessee or Lessee's employees and invitees shall not park in driveways nor occupy parking spaces or other areas reserved for any use such as visitors, delivery, loading, or other tenants. 9. POSSESSION. If Lessor is unable to deliver possession of the Premises to Lessee on the lease commencement date specified in Section 1.8 for any reason whatsoever, this Lease shall not be void or voidable for a period of sixty (60) days thereafter, nor shall Lessor be liable to Lessee for any loss or damage resulting therefrom, but the rent shall abate until the Lessor delivers possession of the Premises to Lessee. If Lessor is unable to deliver possession of the Premises within sixty (60) days after the lease commencement date specified in Section 1.8, this Lease may be terminated by Lessee by written notice to Lessor at any time thereafter prior to date possession is delivered to Lessee. Lessor agrees that Lessee, upon paying the rent and observing all terms, covenants and conditions of this Lease shall peaceably and quietly have, hold and enjoy the Premises against any adverse claim of Lessor, or any party claiming under Lessor, during the Lease Term. In the event that Lessor permits Lessee to occupy the Premises prior to the lease commencement date specified in Section 1.8, the Lessee's occupancy shall be subject to all terms, covenants and conditions of this Lease. The early occupancy by Lessee, as contemplated by Section 49, shall not advance the lease termination date. 10. USE. Lessee shall use the Premises solely for the purpose specified in Section 1.11, and for no other purpose without the prior written consent of Lessor. 10.1. NUISANCE. Lessee shall not use the Premises or the Common Area, and shall insure that Lessee's employees and visitors do not use the Premises or the Common Area, in any manner which interferes with the peaceful enjoyment of the building of which the Premises are a part or the Common Area by other lessees, their respective employees and invitees. Lessee shall not, and shall not permit, the placing of litter in or about the building of which the Premises are a part or the Common Area (except in dumpsters designated for Lessee's use by Lessor) and shall not permit any animal, motorcycle, or road vehicle to be brought into or kept within the Premises. 10.2.

HAZARDOUS MATERIALS. (a) Lessee shall not and Lessee shall not permit any of Lessee's agents, invitees or employees to, release or threaten to release any "oil,""hazardous material", "hazardous wastes" or "hazardous substances" (the "Hazardous Materials") as those terms are defined under the Comprehensive Environmental Response, Compensation, and Liability Act, 42 U.S.C. (S)9601 et -- seq., as amended, the Resource Conservation and Recovery Act of 1976, 42 U.S.C. - ---- (S)6901 et seq., as amended, and regulations adopted thereunder or under any state or local law, rule or regulation regarding Hazardous Materials (the "Hazardous Materials Laws") on or into the Premises, the Common Area or any portion of the real property of which the Premises are a part, including easements appurtenant thereto. Lessee shall not and Lessee shall not permit Lessee's agents and employees to, transport, treat, store or dispose of any Hazardous Materials in such a manner as to violate, or result in potential liabilities under any Hazardous Materials Laws. Lessee shall not, and shall not permit any of Lessee's agents and employees to, transport, treat, store or dispose of any gunpowder, dynamite, gasoline, except as normally stored in vehicles, etc., or other explosive material on or to the Premises, the Common Area or any portion of the real property of which the Premises are a part. (b) Lessor shall indemnify and hold harmless Lessee from and against any claims, demands, or losses resulting from or arising out of the presence of any Hazardous Material on, in or under the Premises prior to Lessee's occupancy, including but not limited to, soil and/or groundwater contamination. Pacific Freeport Industrial Park Page 4 (Westinghouse Electric Corporation)

Lessor shall indemnify and hold Lessee harmless from and against any claims, demands, or losses resulting from or arising out of the presence of any hazardous substances, oil or petroleum product or residue of any other substance or material actionable under federal, state or local law, regulation or ordinance, present on, in or under the Premises prior to Lessee's occupancy, including but not limited to, soil and/or groundwater contamination. 10.4. WATER USE. Waste, excessive use or unusual use of water shall not be allowed. 10.5. WASTE. Lessee agrees that Lessee will not commit or suffer any waste of the Premises. 11. COMMON AREA. The lease of the Premises to the Lessee includes the use in common with others entitled thereto of the Common Area, subject however to the terms, covenants and conditions of this Lease and to reasonable rules and regulations for the use thereof as prescribed pursuant to Section 45. 12. SERVICES. Lessee shall pay for all sewer, water, heat, telephone, electricity, air conditioning, gas, burglar and/or fire alarm, and other utilities supplied to the Premises together with any taxes thereon, other than those services set forth in Section 1.12 as Lessor's responsibility, which responsibility shall exist in Lessor only so long as Lessee is not in default of this Lease. The electricity and gas service to the Premises are separately metered. Lessee shall pay a reasonable proportion based on the square feet leased of all charges jointly metered with other premises. Lessor shall not be liable to Lessee or to any other party for injury to Lessee's business, loss of income therefrom, or any claim, injury, or damage of any kind whatsoever which may arise or accrue in case of the interruption of the supply of water, heat, telephone, electricity, air conditioning, gas, burglar and/or fire alarm, or other utility, caused by accident, failure of power supply, repairs, strikes, fire, flood, act of God, or on account of any defect of the Premises or the building of which the Premises are a part, nor shall any such interruption be grounds for termination of this Lease provided Lessor exercises reasonable diligence to remedy such interruption. 13. CONDITION OF PREMISES. Lessee's taking possession of the Premises and occupying the Premises for thirty (30) days without giving written notice to Lessor within the thirty (30) day period of any defect (excluding only latent or hidden defects which could not be discovered in the exercise of Lessee's reasonable diligence) in the Premises shall be conclusive evidence as against Lessee that the Premises were in good order and satisfactory condition when Lessee took possession of the Premises. No promise to alter, remodel, or improve the Premises or the building of which the Premises are a part and no representation respecting the condition of the Premises or the building of which the Premises are a part, have been made by Lessor to Lessee, unless the promise or representation is set forth in a writing signed by the Lessor. Lessee waives all right to make repairs at the Lessor's expense, or to deduct the cost of repairs from the rent. Lessee hereby accepts the Premises subject to all applicable zoning, municipal, county and state laws, ordinances governing and regulating the use of the Premises, and accepts this Lease subject thereto and to all matters disclosed thereby. Lessee acknowledges that neither Lessor nor Lessor's agent, if any, has made any representation or warranty as to the suitability of the Premises for the conduct of Lessee's business. Lessor warrants that the Premises are in compliance with all current laws, ordinances, regulations and codes and there is no asbestos on the Premises. 14. ALTERATIONS. (a) Lessee shall have, upon notice to Lessor but without Lessor's consent, the right to make such alterations, additions, or improvements in or to the Premises as it shall consider necessary or desirable for the conduct of its business, the cost of which in each case does not exceed $5,000.00 (excepting any work requiring roof penetrations regardless of the cost of such work). All other alterations, additions, or improvements (including any work requiring roof penetrations regardless of the cost of such work) shall not be made without first obtaining the written consent of Lessor, which consent shall not be unreasonably withheld or delayed. Pacific Freeport Industrial Park Page 5 (Westinghouse Electric Corporation)

All such work shall be done in a good and workmanlike manner, and the structural integrity of any building shall be not impaired, and that no liens shall attach to the Premises by reasons thereof. Upon the termination of this Lease, such alterations, additions, or improvements shall, at the option of the Lessor, (1) become the property of Lessor, or (2) be removed by the Lessee provided that any part of the Premises affected by such removal shall be restored to its original condition, reasonable wear and tear excepted. (b) Lessee shall have the right to install in or place on the Premises such fixtures, machines, tools, or other equipment (including but not limited to trade fixtures, lighting fixtures, water coolers, and air conditioning equipment) as it may choose. Such fixtures, machines, tools, or other equipment shall at all times remain the personal property of Lessee regardless of the manner or degree of attachment thereof to the Premises and may be removed at any time by Lessee whether at the termination of this Lease or otherwise; provided, however, that any part of the Premises affected by such removal shall be restored to its original condition, reasonable wear and tear excepted. (c) Notwithstanding whether Lessor's consent is required for any alteration, addition, improvement or change to the Premises, Lessee specifically agrees that Lessee will not make any penetration whatsoever into the floor of the building of which the Premises are a part unless and until Lessor shall have specifically agreed to the placement of any such penetration. 15. LESSEE'S REPAIR OBLIGATIONS. Lessee shall, at Lessee's sole expense, keep the Premises in good order, condition, and repair during the Lease Term, including without limitation the replacement of all broken glass with glass of the same size and quality under the supervision and with the approval of Lessor, and the maintenance of all skylights and doors, except for damage caused by any negligent act or omission, or intentional misconduct, of Lessor, Lessor's agents and employees. If Lessee does not make repairs promptly and adequately, Lessor may (upon such continued failure after ten (10) days written notice), but need not, make repairs, and Lessee shall pay promptly the reasonable cost thereof. At any time or times, Lessor, either voluntarily or pursuant to governmental requirement, may, at Lessor's sole expense, make repairs, alterations, or improvements in or to the Premises or the building of which the Premises are a part, and during such operations Lessor may close entrances, doors, corridors, elevators, or other facilities, all without any liability to Lessee by reason of interference, inconvenience, or annoyance; provided that Lessee shall have access to the Premises sufficient for conduct of Lessee's business. In the event Lessee requests that repairs, alterations, decorating, or other work in the Premises be made during periods other than ordinary business hours, Lessee shall pay Lessor for overtime and other additional expenses incurred by Lessor because of such requests. Lessor, or Lessor's agents or representatives, may come into and upon Premises at all reasonable times, or any time in case of emergency, for purposes of examining the Premises. Lessee shall repair any damage occasioned by the moving of freight, furniture or other objects into, within, or from the building of which the Premises are a part. 16. LESSOR'S REPAIR OBLIGATIONS. Lessor shall, at Lessor's sole expense, keep the foundations, the exterior walls, floors, and the roof, including skylights, of the building of which the Premises are a part, all plumbing, sewer, gas and electrical systems from within the interior walls and floors of the Premises to the utility provider, and all Common Area in good order, condition and repair during the Lease Term and for two years from occupancy Lessors warrants all leasehold improvements, subject to the terms, covenants and conditions Section 42 hereof, and except for damage caused by any negligent act or omission, or intentional misconduct, of Lessee, Lessee's agents, and employees or invitees. 17. LIENS. Lessee agrees to keep the Premises and the property on which the Premises are located free from any liens arising out of any work performed, materials furnished, or obligations incurred by Lessee, except if performed by Lessor. In the event liens are filed as a result of Lessee's work, then Lessee shall promptly cause the same to be released or satisfied in full within ten (10) days of the date of such filing. Pacific Freeport Industrial Park Page 6 (Westinghouse Electric Corporation)

18. INDEMNIFICATION. Lessee waives all claims against Lessor and hereby releases Lessor for damages to property, or to goods, wares and merchandise stored in, upon, or about the Premises, and for injuries to persons in, upon, or about the Premises from any cause arising at any time, unless the damage or injury was caused by the negligent act or omission, or intentional misconduct, of Lessor. Lessee agrees to indemnify and hold Lessor harmless from and on account of any damage or injury to any person or property arising from the use of the Premises by Lessee or from the failure of Lessee to keep the Premises in good condition as provided in Section 15, unless such damage or injury was caused by the negligent act or omission, or intentional misconduct, of Lessor. Lessor shall not be liable to Lessee for any damage because of any negligent act or omission, or intentional misconduct, of any co-tenant or other occupant of the same building of which the Premises are a part, or by any owner or occupant of adjoining or contiguous property, nor for overflow, breakage, or leakage of water, steam, gas, or electricity from pipes, wires, or otherwise. Lessee shall pay for all damage to the building of which the Premises are a part and to the tenants and occupants thereof caused by the misuse or neglect of the Premises by Lessee or Lessee's invitees. 19. INSURANCE REQUIRED OF LESSEE. Lessee, at Lessee's sole expense, shall provide and keep in force during the Lease Term and for the benefit of both Lessor and Lessee general commercial liability insurance policies with a recognized casualty insurance company qualified to do business in Nevada protecting Lessee against any and all liability occasioned by the use, occupancy, disuse or condition of the Premises, improvements thereto, adjoining areas or ways or otherwise, in an initial amount of not less than Two Million Dollars ($2,000,000.00) per occurrence such insurance shall further name Lessor as an additional insured. Lessee agrees to furnish certificates of insurance to Lessor naming Lessor as Additional Insured. A certificate of the policy, together with evidence of payment of premiums, shall be deposited with the Lessor on or prior to the lease commencement date, and on renewal of the policy not less than thirty (30) days before expiration of the policy. All the insurance required under this Section 19 shall (a) be issued as a primary policy; and (b) contain an endorsement requiring thirty (30) days written notice from the insurance company to both parties and Lessor's lender before cancellation or change in the coverage, scope, or amount of any policy. The limits of the insurance shall not limit the liability of the Lessee under this Lease. Lessee shall not use or keep on the Premises any article which Lessor's insurance carrier terms as hazardous and which tends to increase Lessor's rate of insurance. Lessee agrees that Lessor and Lessor's insurance carrier may make regular or unannounced inspections of the Premises and Lessee agrees to protect the Premises in accordance with the insurance carrier's engineering standards and recommendations. 20. INSURANCE REQUIRED OF LESSOR. Lessor agrees to carry fire and casualty insurance during the Lease Term insuring Lessor's interest in the Premises for the full replacement value thereof. Lessor shall have no obligation to insure against loss or damage to Lessee's leasehold improvements, fixtures, furniture, or other personal property in or about the Premises. Lessee shall have no interest in the proceeds of any insurance insuring Lessor's interest. Lessee shall pay Lessee's pro rata share of the fire and casualty insurance premiums to the Lessor monthly in advance as additional rent commencing on the lease commencement date specified in Section 1.8 and continuing on the first day of each month thereafter for the remainder of this Lease. Lessee's pro rata share of the insurance cost shall be measured by the percentage of the building occupied by Lessee as specified in Section 1.14. 21. SUBROGATION. Lessor and Lessee hereby waive all claims they may have and all rights of subrogation which their respective insurers might have under all policies of insurance now existing or hereafter purchased during the Lease Term by either Lessor or Lessee, respectively, for any damage or loss covered by such policies to the Premises or any portion thereof, or which could be covered by all risk insurance, or Lessee's leasehold improvements, furniture, fixtures, personal property, business, or operations in or about the Premises. Lessee and Lessor shall, upon obtaining the policies of insurance required under this Section 21, give notice to their respective insurance carriers that the foregoing mutual waiver of subrogation is contained in this Lease. This waiver of subrogation shall be effective as to any insurance policy. Pacific Freeport Industrial Park Page 7 (Westinghouse Electric Corporation)

22. PERSONAL PROPERTY TAXES. Lessee shall pay before delinquency all taxes, assessments, license fees and other charges that are levied and assessed against Lessee's personal property installed or located in or on the Premises, and that become payable during the Lease Term. On demand by Lessor, Lessee shall furnish Lessor with satisfactory evidence of these payments. 23. REAL PROPERTY TAXES. Lessee shall pay to Lessor as additional rent Lessee's pro rata share, based upon the percentage of the building occupied by Lessee as set forth in Section 1.14, of all Real Property Taxes, as defined below, levied and assessed against the real property of which the Premises are a part. Since Lessor is required to pay real property taxes in quarterly installments in advance for each annual fiscal tax year, the Lessee's share of the Real Property Taxes shall be payable in quarterly installments in advance, commencing on the lease commencement date, and continuing on the first day of each calendar quarter thereafter for the remainder of this Lease. The term "Real Property Taxes," as used in this Section 23, means any form of assessment, license fee, rent tax, levy, penalty (other than income, inheritance or estate tax) imposed by any authority having the direct or indirect power to tax, including any city, county, state or federal government, or any school, agricultural, lighting, drainage or improvement district, as against any legal or equitable interest of Lessor in the Premises or in the real property of which the Premises are a part, as against Lessor's right to rent or gross receipts therefrom, or as against Lessor's business of leasing the Premises and Lessee shall pay Lessee's pro rata share of any and all charges which may be imposed by governmental regulations or authorities. Nothing herein to the contrary shall require Lessee to pay any portion of any tax on Lessor's gross income or any franchise tax or any estate gift or inheritance tax. Any failure to pay the quarterly installments of Real Property Taxes shall be deemed a failure to pay rent and shall constitute a default of this Lease. Lessor and Lessee agree that in collecting Lessee's quarterly installments of Real Property Taxes, Lessor does not act as trustee for Lessee or any other person. Lessor acts only as a creditor of Lessee in collecting the quarterly installments of Real Property Taxes. Lessor may commingle the installments of Real Property Taxes with Lessor's general funds and shall pay no interest on them. Lessee's liability to pay Real Property Taxes shall be prorated on the basis of a 365-day year to account for any fractional portion of a fiscal tax year included in the Lease Term at its commencement and termination. Lessee shall be considered the owner during the Lease Term of any leasehold improvements installed at Lessee's expense, and any such leasehold improvements may be assessed to Lessee for property tax purposes. 24. DESTRUCTION. In the event of a partial destruction of the Premises or the building of which the Premises are a part during the Lease Term from a cause which is insured under Lessor's fire and extended coverage insurance, Lessor shall forthwith repair the same, provided such repairs can reasonably be made within one hundred twenty (120) days under the laws and regulations of the state, county, federal, or municipal authorities, but such partial destruction shall not annul or void this Lease, except that Lessee shall be entitled to a proportionate reduction of rent while such repairs are being made, such proportionate reduction to be based upon the extent to which the making of such repairs interferes with the business carried on by Lessee on the Premises. If such repairs cannot be made within one hundred twenty (120) days, or if the Premises are destroyed to the extent of more than 33-1/3 % of the then current replacement cost thereof, either Lessor or Lessee may terminate this Lease by giving written notice to the other party within thirty (30) days after the damage occurs. If this Lease is not terminated, Lessor shall make such repairs within a reasonable time with this Lease continuing in full force and effect and the rent proportionately reduced while the repairs are being made. If the Premises or the building of which the Premises are a part are partially destroyed or damaged during the last three (3) months of the Lease Term, or any renewal thereof, Lessor may elect to terminate this Lease as of the date of occurrence of such damage by giving written notice of termination to Lessee within thirty (30) days after the damage occurs. Pacific Freeport Industrial Park Page 8 (Westinghouse Electric Corporation)

In the event the building of which the Premises are a part is destroyed to the extent of more than 33-1/3% of the then current replacement cost thereof, Lessor may elect to terminate this Lease by giving written notice of termination to Lessee within thirty (30) days after damage occurs, regardless of whether the Premises are damaged or whether the repairs can reasonably be made within one hundred twenty (120) days. A total destruction of the Premises or the building of which the Premises are a part shall terminate this Lease. In the event of termination of this Lease pursuant to any of the terms, covenants and conditions of this Section 24, rent and Lessee's portion of any property taxes and insurance costs shall be apportioned on a per diem basis and shall be paid to the date of the casualty. In no event shall Lessor be liable to Lessee for any damages resulting to Lessee from the happening of such casualty or from the repairing or reconstruction of the Premises or of the building, or from the termination of this Lease as herein provided, nor shall Lessee be relieved thereby or in any such event from Lessee's obligations under this Lease except to the extent and upon the conditions expressly stated in this Section 24. 25. EMINENT DOMAIN. If the whole or any substantial part of the Premises or the building of which the Premises are a part shall be taken or condemned by any competent authority for any public use or purpose, the Lease Term shall end upon, and not before, the date when the possession of the part so taken shall be required for such use or purpose. Rent shall be apportioned as of the date of such termination. Lessee shall be entitled to receive any damages awarded by the court for leasehold improvements installed at Lessee's expense and the expenses of Lessee's relocation or business interruption if so awarded and designated by the court. The entire balance of the award shall be the property of Lessor. 26. ASSIGNMENT AND SUBLETTING. Lessee shall not directly or indirectly assign, hypothecate or encumber this Lease, or any interest herein, and shall not sublet the Premises or any part thereof, or any right or privilege appurtenant thereto, or suffer any other person (excepting only Lessee's agents and employees) to occupy or use the Premises, or any portion thereof, without the prior written consent of Lessor, and a consent to one assignment, hypothecation, encumbrance, subletting, occupation, or use by any other person shall not be deemed to be a consent to any subsequent assignment, hypothecation, encumbrance, subletting, occupation, or use by any other person. Any such assignment, hypothecation, encumbrance, subletting, occupation or use without such consent shall be void, and shall, at the option of Lessor, terminate this Lease. Any transfer or assignment of this Lease by operation of law without the written consent of Lessor shall make this Lease voidable at the option of Lessor. Lessor will not unreasonably withhold or delay Lessor's consent to an assignment or subletting by Lessee, provided that (a) the assignee or sublessee proposes to use the Premises for the same use as is set forth in Section 1.11; (b) the proposed use is not injurious to the Premises and will not disturb other tenants of Lessor in the building of which the Premises are a part or immediate vicinity; and (c) the assignee or sublessee executes and delivers to Lessor a written assumption of this Lease in form acceptable to Lessor. Notwithstanding the foregoing, Lessee shall have the right to assign this Lease or to sublet the Premises or any part thereof to any entity controlled, controlling or under common control with Lessee or the purchaser of the business (by merger or acquisition) of the business conducted on the Premises without the consent of Lessor, provided, however, that no such assignment or subletting shall relieve Lessee of its duty to perform fully all of the agreements, covenants, and conditions set forth in this Lease. Lessee shall promptly advise Lessor of any such permitted assignment or subletting and of the name and address of the assignee or subtenant, as the case may be. Regardless of Lessor's consent, no subletting or assignment shall release Lessee or Lessee's obligation or alter the primary liability of Lessee to pay any rent and to perform all other obligations to be performed by Lessee under this Lease. The acceptance of any rent by Lessor from any other person shall not be deemed to be a waiver by Lessor of any term, covenant or condition of this Lease. Every assignment or sublease shall recite that it is and shall be subject and subordinate Pacific Freeport Industrial Park Page 9 (Westinghouse Electric Corporation)

to the terms, covenants and conditions of this Lease, and the termination of this Lease shall constitute a termination of every such assignment or sublease. 27. SUBORDINATION. The rights of Lessee under this Lease shall be and they are subject and subordinate at all times to the lien of any mortgage or deed of trust, now or hereafter in force against the Premises and the property of which the Premises are a part, and to all advances made or hereafter to be made upon the security thereof, and Lessee shall execute such further instruments subordinating this Lease to the lien of any such encumbrance, as shall be requested by Lessor, provided the holder of such encumbrance agrees to recognize Lessee's interest under this Lease if Lessee is not then in default. If any mortgagee or beneficiary elects to have this Lease superior to its mortgage or deed of trust and gives notice of such fact to Lessee, then this Lease shall be deemed superior to the lien of any such encumbrance, whether this Lease or a memorandum thereof is dated or recorded before or after said encumbrance. As a condition to the effectiveness of this Lease, Lessor shall further secure a nondisturbance and attornment agreement in favor of Lessee in reasonable form from the current mortgagee or lien holder or any future mortgagee or lien holder on the building which shall provide that as long as Lessee is not in default in the payment of rental or any other covenants or conditions of the lease, the rights of Lessee under the lease shall not be terminated and the possession of Lessee shall not be disturbed by Lessor or any mortgagee or ground Lessor or by any proceedings regarding the debt which any such mortgage or ground lease secures. 28. SIGNS. Lessee shall not place any signs, lettering, marks, photographs, or any other material whatsoever, on the interior or exterior of the doors, windows, hallways, or any other place, in, on, or about the Premises, the building of which the Premises are a part, or its appurtenances, without Lessor's prior written approval, which approval shall not be unreasonably withheld or delayed, of the size, style, design, color, material, manner of applying or fastening, and location thereof. 29. DEFAULT. (a) If Lessee shall fail to pay any rent to Lessor when the same is due and payable under the terms of this Lease and such default shall continue for a period of ten (10) days after written notice thereof has been given to Lessee by Lessor, or if the Lessee shall fail to perform any other duty or obligation imposed upon it by this Lease and such default shall continue for a period of thirty (30) days after written notice thereof has been given to Lessee by Lessor, or if the Lessee shall be adjudged bankrupt, or shall make a general assignment for the benefit of its creditors, or if a receiver of any property of Lessee in or upon the Premises be appointed in any actions, suit, or proceeding by or against Lessee and such appointment shall not be vacated or annulled within sixty (60) days, or if the interest of Lessee in the Premises shall be sold under execution or other legal process, then and in any such event Lessor shall have the right to enter upon the Premises and again have, repossess, and enjoy the same as if this Lease had not been made, and thereupon this Lease shall terminate without prejudice, however, to the right of Lessor to recover from Lessee all rent due and unpaid up to the time of such re-entry. In the event of any such default and re-entry, Lessor shall have the right to relet the Premises for the remainder of the then existing term whether such term be the initial term of this Lease or any renewed or extended term, for the highest rent then obtainable, and to recover from Lessee the difference between the rent reserved by this Lease and the amount obtained through such reletting less the costs and expenses reasonably incurred by Lessor in such reletting. (b) If Lessor shall fail to perform any duty or obligation imposed upon it by this Lease and such default shall continue for a period of thirty (30) days after written notice thereof has been given by Lessee, then and in such event Lessee may, at its option, terminate this Lease without prejudice to is right to recover appropriate damages from Lessor. Upon termination of the lease pursuant to this provision, all obligations of Lessee arising under this Lease, including payment of rent, shall cease. Pacific Freeport Industrial Park Page 10 (Westinghouse Electric Corporation)

30. ABANDONMENT. Lessee shall not abandon or surrender the Premises during the Lease Term, and if Lessee does or is dispossessed by process of law, or otherwise, any personal property belonging to Lessee left on the Premises shall be deemed to be abandoned at the option of Lessor. 31. REMOVAL OF PROPERTY UPON TERMINATION. At any time Lessee may, and, prior to the applicable termination date of the Lease Term, Lessee shall remove from the Premises furniture, equipment, other personal property and any trade fixtures installed by Lessee or at Lessee's expense. Lessee shall not remove any trade fixtures installed by Lessor or Lessor's expense or any other fixtures or leasehold improvements without Lessor's prior written consent: provided, however, that upon Lessor's written request, Lessee shall remove such trade fixture, other fixtures and leasehold improvements. Lessee shall repair any damage to the Premises caused by removal of any property and shall restore the Premises to its condition at the lease commencement date, less reasonable wear and tear. All removal and restoration shall be accomplished at Lessee's sole expense prior to the end of the Lease Term. 32. REMOVAL, STORAGE AND LIEN OF PROPERTY UPON DEFAULT. [Intentionally Omitted] 33. SURRENDER. The voluntary or other surrender of this Lease by Lessee, or a mutual cancellation thereof, shall not work a merger, and shall, at the option of Lessor, terminate all or any existing subleases or subtenancies, or may, at the option of Lessor, operate as an assignment to Lessor of any or all such subleases or subtenancies. 34. LESSOR'S CONVEYANCE. Lessor may convey its interest in the Premises and all or any portion of the Common Area. From and after the date of such conveyance, Lessor shall be released and discharged from any and all obligations under this Lease, excepting those obligations previously accrued. 35. WAIVER. The waiver by Lessor of any breach of any term, covenant or condition of this Lease shall not be deemed to be a waiver of such term, covenant or condition or any subsequent breach of the same or any other term, covenant or condition of this Lease. The subsequent acceptance of rent under this Lease by Lessor shall not be deemed to be a waiver of any preceding breach by Lessee of any term, covenant or condition of this Lease, other than the failure of Lessee to pay the particular rent so accepted, regardless of Lessor's knowledge of such preceding breach at the time of acceptance of such rent. 36. HOLDING OVER. Any holding over after the applicable termination date, with the consent of Lessor, shall be construed to be a tenancy from month to month on the same terms, covenants and conditions specified herein so far as applicable but shall not be deemed to constitute an extension or renewal of this Lease. During any period of holding over the monthly rent shall be the then monthly rent in effect, provided however that in the event such holding over continues for a period of two (2) months, the monthly rent shall be increased by twenty percent (20%) over the then monthly rent in effect. 37. ATTORNEY'S FEES. If either party becomes a party to litigation concerning this Lease by reason of any act or omission of the other party or its authorized representatives, and not by any act or omission of the party that becomes a party to that litigation or any act or omission of its authorized representatives, the party that causes the other party to become involved in the litigation shall be liable to that party for reasonable attorney's fees and court costs incurred by it in the litigation. If any action at law or in equity shall be brought to recover any rent under this Lease, or for or on account of any breach of or to enforce or interpret any of the terms, covenants or conditions of this Lease, or for the recovery of the possession of the Premises, the prevailing party in any final judgment, or the nondismissing party in the event of a dismissal without prejudice, shall be entitled to the full cost of all reasonable expenses, including all court costs and reasonable attorney's fees paid or incurred in good faith. 38. REMEDIES. All of the remedies herein provided are cumulative, and in addition to and not in lieu of the remedies provided by law, and the exercise of one remedy shall not preclude the exercise of any other remedy. Pacific Freeport Industrial Park Page 11 (Westinghouse Electric Corporation)

Notice to Lessor shall be given in writing and sent by certified mail, return receipt requested, addressed to Lessor at the address to which the rent is paid. 40. COMMISSION.

(The Premises and the Improvements are sometimes hereinafter collectively called the "Leased Premises".) NOW, THEREFORE, WITNESSETH, That Landlord hereby demises and leases unto Tenant, and Tenant hereby takes and hires from Landlord the Leased Premises, subject to the terms and conditions hereof. Term. TO HAVE AND TO HOLD the Leased Premises unto Tenant for a term of ---- five (5) years commencing at 12:01 A.M. on October 1, 1997 (the "Commencement Date") and ending at 11:59 P.M. on September 30, 2002; subject nevertheless, to the following covenants and conditions which Landlord and Tenant respectively covenant and agree to keep and perform. 1. Rent. See Rider Item #3. ---- 2. Taxes. See Rider Item #7. Tenant will pay to Landlord on demand and ----- as additional rental hereunder all real estate taxes (including taxes levied or assessed in lieu of or as a substitution for real estate taxes) imposed, assessed or levied upon or against the Leased Premises during the term of this Lease. In addition, Tenant will pay to Landlord on demand as additional rental hereunder, each and every item of expense in the nature of a tax or imposition for the payment of which Landlord is or shall become liable by reason of Landlord's estate or interest in the

Leased Premises, or any portion thereof, including without limiting the generality thereof all personal property taxes, sales taxes, excise taxes, use and occupancy taxes, whether or not the same are now customarily levied or enacted and regardless of whether the same shall be general or special, foreseen or unforeseen, provided the same shall be (i) levied or assessed against Landlord or Tenant in connection with the Leased Premises, or any portion thereof, or (ii) levied, assessed or imposed upon or against, or which shall be measured by, any rents or rental income, as such, payable to Landlord, provided, however, that Tenant shall not be obligated hereunder to pay any of the following: a. any estate, inheritance, devolution, succession, transfer, legacy or gift tax which may be imposed upon or with respect to any transfer of Landlord's interest in the Leased Premises; or b. any net income tax levied upon or against Landlord's income from all sources. 3. Use. Tenant will use and occupy the Leased Premises only for office, --- storage and distribution of Tenant's electrical products and other lawful uses consistent with existing uses of the Tri-County Commerce Park and will not create, permit or maintain any nuisance thereon. Tenant will not use or occupy or suffer or permit the Leased Premises or any part thereof to be used or occupied for (a) any purpose contrary to law or the rules or regulations of any governmental authority having jurisdiction over the Leased Premises (b) any purpose which in the reasonable judgment of Landlord is hazardous or detrimental to persons or property. 4. Maintenance and Repair. See Rider Item #4. Tenant will at Tenant's ---------------------- sole cost and expense keep the Leased Premises and all equipment and personal property of Landlord therein in good order, condition and repair, damage by insured casualty excepted. If Tenant fails or refuses to keep the Leased Premises in good order, condition and repair as aforesaid, Landlord may do so, and charge the cost thereof to Tenant to be collected as additional rental hereunder. Landlord shall, during the term of this Lease, at its sole cost and expense and as promptly as is reasonable under the circumstances, make all needed structural repairs (exclusive of painting) to the Improvements upon receipt of notice from Tenant of the need for such repairs, unless the need for such repairs was caused by the wrongful act or negligence of Tenant, in which event Tenant shall promptly make such repairs at Tenant's sole cost and expense. Structural repairs shall mean only repairs to the roof, exterior walls, rain conductors, floors, foundations and steel frame of the Improvements and the utility service lines running from the main line to the Building. Structural repairs shall be 2

deemed to be needed when the failure to make same will result in a hazard to persons or property and/or cause a significant impairment to Tenant's use of the Leased Premises for the purposes set forth in section 3 hereof. 5. Alterations. Tenant will not make or permit to be made any ----------- alterations, improvements and additions to the Leased Premises or any part thereof except by and with the prior written consent of Landlord, which consent shall not be unreasonably withheld. All alterations, improvements and additions to the Leased Premises shall be made in accordance with all applicable laws and shall at once when made or installed be deemed to have attached to the freehold and to have become the property of Landlord and except as provided in section 12 of this Lease shall remain for the benefit of Landlord at the end of the term of this Lease or other expiration of this Lease in as good order and condition as they were when installed, reasonable wear and tear and damage by insured casualty excepted; provided, however, if at the time of such alterations, the parties hereto agreed that such alterations were to be removed at the termination of this Lease, Tenant shall at Tenant's sole cost and expense promptly remove the alterations, improvements and additions which were placed in the Leased Premises by Tenant and which are designated in said notice and repair any damage occasioned by such removal and restore the Leased Premises to the condition in which they were prior to such alterations, improvements or additions, reasonable wear excepted, and in default thereof Landlord may effect said removals and repairs at Tenant's expense. In the event of making such alterations, improvements and additions as herein provided, Tenant further will indemnify and save harmless Landlord from all reasonable expense, liens, claims or damages or injuries to either persons or property arising out of, or resulting from the undertaking, making or removal of said alterations, additions and improvements. 6. Assignment and Subletting. See Rider Item #5. Tenant shall not ------------------------- assign this Lease or sublet the whole or any part of the Leased Premises or permit any other persons to occupy same without the prior written consent of Landlord. Landlord shall not unreasonably withhold such consent. Any such assignment or subletting, even with the consent of Landlord, shall not relieve Tenant from liability for payment of rent or other sums herein provided or from the obligation to keep and be bound by the terms, conditions and covenants of this Lease. The acceptance by Landlord of rent from any other person shall not be deemed to be a waiver of any of the provisions of this Lease or to be a consent to the assignment of this Lease or subletting of the Leased Premises. Any transfer of this Lease from Tenant by merger, consolidation or liquidation shall constitute an assignment of this Lease and shall require the prior written consent of Landlord, which consent shall not be unreasonably withheld or delayed. 3

An assignment for the benefit of creditors or by operation of law shall not be effective to transfer any rights to an assignee without the prior written consent of the Landlord first having been obtained. 7. Utilities. Tenant will pay for all public and private utility --------- services, including water and sewer rentals, used or consumed on or in connection with the Leased Premises. Electric and gas shall be separately metered, water and sewer to be submetered and invoiced to Tenant by Landlord. 8. Insurance. See Rider Item #6. During the term of this Lease, Tenant --------- will at Tenant's sole cost and expense maintain with insurance companies satisfactory to Landlord comprehensive public liability and property damage insurance with respect to the Leased Premises, with minimum limits of $1,000,000 with respect to the death or injury of one person, and $2,000,000 with respect to the death or injury of two or more persons and $200,000 with respect to property damage. Such insurance coverage shall be endorsed to include the contractual liability assumed by Tenant under section 9 hereof. Prior to the Commencement Date, Tenant shall furnish to Landlord certificates evidencing the comprehensive public liability insurance and property damage coverage as provided in this section 8 above, said certificates and policies to contain the standard 10 day notification clause to Landlord and Landlord's mortgagee in the event of change of cancellation of insurance coverage, and shall name Landlord as an additional insured. 9. Indemnity. See Rider Item #8. Tenant will protect and save and keep --------- Landlord forever harmless and indemnified against and from any penalty or damage or charges imposed for any violation of any law or ordinance, whether occasioned by the neglect of Tenant or those holding under Tenant, and Tenant will at all times protect, indemnify and save and keep harmless Landlord against and from all claims, loss, cost, damage or expense arising out of or from any accident or other occurrence on or about the Leased Premises causing injury to any person or property whomsoever or whatsoever, and will protect, indemnify, save and keep harmless Landlord against and from any and all claims and against and from any and all loss, cost, damage, or expense arising out of any failure of Tenant in any respect to comply with and perform all the requirements and provisions of this Lease. 10. Surrender. Tenant will deliver up and surrender to Landlord --------- possession of the Leased Premises upon expiration of the term of this Lease or upon the earlier termination of this Lease, broom clean and in as good condition and repair as the same shall be at the commencement of the term of this Lease, ordinary wear and tear and damage by insured 4

casualty excepted. Tenant hereby waives any notice now or hereafter required by law with respect to vacating at the termination of any tenancy. 11. Access to Leased Premises. Tenant will permit Landlord or Landlord's ------------------------- agents to inspect or examine the Leased Premises at any reasonable time upon reasonable advanced notice and permit Landlord to make such repairs to the Leased Premises as Landlord may deem necessary for preservation of the Leased Premises and which Tenant has failed so to make without the same being construed as an eviction of Tenant in whole or in part, and the rent shall in no wise abate while such repairs, alterations, improvements or additions are being made by reason of loss or interruption of the business of Tenant because of the prosecution of such work. Landlord shall diligently perform all work referenced herein. Landlord shall have the right to enter upon the Leased Premises at any reasonable time and from time to time during the term of this Lease for the purpose of exhibiting the same to prospective purchasers and for a period commencing 180 days prior to the end of the term of this Lease for the purpose of exhibiting the same to prospective tenants. During said 180-day period Landlord may place signs in or upon the Leased Premises to indicate that same are for rent or sale, which signs shall not be removed, obliterated or hidden by Tenant. Landlord's signs shall not obstruct Tenant's signs. 12. Tenant's Property. All fixtures, equipment and other property placed ----------------- or installed in or on the Leased Premises by Tenant and designed for and used in the conduct of Tenant's business in the Leased Premises, shall at all times be and remain the property of Tenant. Tenant will at Tenant's sole cost and expense remove all such equipment, fixtures and other property from the Leased Premises prior to the termination of this Lease and Tenant will at Tenant's cost and expense repair any and all damage to the Leased Premises caused or occasioned by the installation or removal of said fixtures, equipment or other property. Any and all such equipment, fixtures and other property which shall remain on the Leased Premises for more than five (5) days after the termination of this Lease, shall at Landlord's option be deemed abandoned by Tenant and become the sole property of Landlord, or may be removed by Landlord in which case Tenant shall pay or reimburse Landlord for the reasonable cost of such removal and of repairing any and all damage to the Leased Premises caused thereby. 13. Signs. Tenant may install at Tenant's own cost and expense an ----- appropriate sign or signs on the Leased Premises referring to Tenant's business or services; provided, however, that the size, type and location of any such sign shall comply with all applicable laws and governmental rules, regulations and restrictions and shall be subject to Landlord's approval, which approval shall not be unreasonably withheld or delayed. 5

14. Condemnation of the Leased Premises. If the Leased Premises or any ----------------------------------- part thereof shall be taken or condemned either permanently or temporarily for any public use or purpose by any competent authority in condemnation proceedings or by any right of eminent domain, the entire compensation award thereof, both leasehold and reversion, shall belong to the Landlord without any deduction therefrom for any present or future estate of Tenant, and Tenant hereby assigns to Landlord all its right, title and interest to any such award. Tenant shall, however, be entitled to claim, prove and receive in such condemnation proceedings such award as may be allowed for moving and relocation expenses, fixtures and other equipment installed by Tenant, but only if such award shall be in addition to the award for the Leased Premises. If substantially all of the Leased Premises shall be taken as aforesaid or if any such taking shall render the Leased Premises unfit for the conduct of Tenant's business, then this Lease shall terminate and shall become null and void from the time possession thereof is required for public use, and from that date the parties hereto shall be released from all further obligations hereunder. If only a portion of the Leased Premises shall be so taken or condemned, which taking shall not materially render the Leased Premises unfit for the conduct of Tenant's business, then Landlord at its own expense shall with all reasonable dispatch repair and restore the portion not affected by the taking and this Lease shall continue in full force and effect except that the rental shall be equitably and proportionately reduced. 15. Damage or Destruction. See Rider Item #15. If, during the term of --------------------- this Lease, the Improvements are so damaged or destroyed by insured casualty so as to render the Improvements unfit for occupancy by Tenant for the purposes set forth in section 3 of this Lease, and if the Improvements cannot in the sole judgment of Landlord be repaired, restored or rebuilt within five (5) months from the happening of such damage or destruction, then Landlord or Tenant may terminate this Lease as of the date of such damage by giving the other notice in writing with respect thereto within thirty (30) days from the date of such happening. In such case, rental hereunder shall abate as of the date of such damage or destruction and Landlord shall be entitled to retain all insurance proceeds resulting from such damage or destruction. Landlord shall refund to Tenant any unearned rent paid in advance and Tenant shall as expeditiously as is reasonable under the circumstances remove such of its property as it is required to remove under the provisions of section 12 hereof and shall surrender the Leased Premises to Landlord who may enter upon and repossess the same, and all further liability Tenant and Landlord hereunder shall thereupon cease. 6

In the event any such damage to or destruction of the Improvements can in the sole judgment of Landlord be repaired within a period of five (5) months after the happening thereof, Landlord shall repair, restore or rebuild the Improvements and Tenant's Improvement with all reasonable dispatch and in a good workmanlike manner, and this Lease shall not be affected in any manner, except that the liability of Tenant for rent shall be suspended for the period during which such repair, restoration or rebuilding is being made. However, if the damage is such as not to render the Improvements totally unfit for the occupancy by Tenant for the purposes set forth in section 3 of this Lease, Landlord shall repair the Improvements with all reasonable dispatch and rentals hereunder shall abate pro rata to the extent that portions of the Leased Premises are not available for use by Tenant. In either situation provided for in this paragraph, Landlord shall be entitled to receive and retain all insurance proceeds resulting from such damage or destruction. Notwithstanding the foregoing provisions of this section 15, if the Improvements shall be destroyed or in the judgment of Landlord substantially damaged by insured casualty during the last two (2) years of the term of this Lease, Landlord may, within 30 days after the occurrence of such damage or destruction, cancel and terminate this Lease by giving written notice to Tenant, and if such notice is given, this Lease shall expire as of the date of such destruction with the same effect as though that date was the date of the expiration of the term of this Lease, rental hereunder shall abate as of the date of such damage or destruction, Landlord shall be entitled to retain all insurance proceeds resulting from such damage or destruction, Landlord shall refund to Tenant any unearned rent paid in advance, and Tenant shall as expeditiously as is reasonable under the circumstances remove such of its property as it is required to remove under the provisions of section 12 hereof and shall surrender the Leased Premises to Landlord who may enter upon and repossess the same, and all further liability Tenant and Landlord hereunder shall thereupon cease. If this Lease is not so cancelled and terminated, the provisions of the foregoing paragraphs of this section 15 shall control. 16. Default and Remedies. See Rider Item #16. All rights and remedies -------------------- of Landlord herein enumerated shall be cumulative, and none shall exclude any other rights or remedies allowed by law. Tenant covenants and agrees that if any of the following events of default occur, that is, if: a. Tenant shall fail, neglect or refuse to pay any rent or sums payable hereunder as rent at the time and in the amount as herein provided, or to pay any other monies agreed by it to be paid promptly when and as the same shall become due and payable under the terms hereof, or if Tenant shall fail to keep and maintain in full force and effect the insurance required under section 8 of this Lease, and if 7

any such default should continue for a period of more than 10 days after notice thereof by Landlord to Tenant; or b. Tenant commit waste thereon, or any execution be issued against a substantial part of Tenant's assets or bankruptcy, receivership or insolvency proceedings be instituted by or against Tenant or an assignment made by Tenant for the benefit of creditors, or Tenant shall fail, neglect or refuse to keep and perform any of the other covenants, conditions, stipulations or agreements herein contained and covenanted and agreed to be kept and performed by it, and in the event any such failure, neglect or refusal shall continue for a period of more than 30 days after notice thereof is given in writing to Tenant by Landlord, provided, however, that if the cause for giving such notice involves the making of repairs or other matters reasonably requiring a longer period of time than the period of such notice, Tenant shall be deemed to have complied with such notice so long as it has commenced to comply with said notice within the period set forth in the notice and is diligently prosecuting compliance of said notice or has taken the proper steps or proceedings under the circumstances to prevent the seizure, destruction, alteration or other interference with said Leased Premises by reason of non-compliance with the requirements of any law or ordinance or with the rules, regulations or directions of any governmental authority, as the case may be; then the present value of the entire rental for the balance of the term of this Lease discounted at 8% per annum shall at the option of Landlord at once become due and payable as if by the terms of this Lease it is payable in advance, and if not so paid the Tenant does hereby authorize and fully empower Landlord to cancel or annul this Lease at once and in compliance with the laws of Pennsylvania to re-enter and take possession of the Leased Premises immediately, without any previous notice of intention to re-enter, and to remove all persons and their property therefrom, and to use such assists in effecting and perfecting such removal of Tenant as may be necessary and advisable to recover at once first and exclusive possession of the Leased Premises, without being deemed guilty of any manner of trespass and without prejudice to any remedies which might otherwise be used by Landlord, in which event this Lease shall terminate and Tenant shall indemnify Landlord against all unavoidable loss of rent which Landlord may incur by reason of such termination during the residue of the term of this Lease. Landlord may, however, at its option at any time and after such default or violation of condition or covenant, in compliance with the laws of Pennsylvania, re-enter and take possession of the Leased Premises without such re-entry working a forfeiture of the rents to be paid and the covenants, agreements and conditions to be kept and performed by Tenant for the term of this Lease. In such event Landlord shall have the right, but not the 8

obligation, to divide or subdivide the Leased Premises in any manner Landlord may determine and make reasonable efforts to lease or let the same or portions hereof for such periods of time and at such rentals and for such use and upon such covenants and conditions as Landlord may elect, applying the net rentals from such letting first to the payment of Landlord's reasonable expenses incurred in dispossessing Tenant and the reasonable cost and expense of making such improvements in the Leased Premises as may be necessary in order to enable Landlord to re-let the same, and to the payment of any reasonable brokerage commissions or other necessary expenses of Landlord in connection with such re- letting. The balance, if any, shall be applied by Landlord from time to time on account of the payments due or payable by Tenant hereunder, with the right reserved to Landlord to bring such action or proceedings for the recovery of any deficits remaining unpaid as Landlord may deem desirable from time to time, without being obligated to await the end of the Term for the final determination of Tenant's account. Any balance remaining, however, after full payment and liquidation of Landlord's account as aforesaid shall be paid to Tenant, with the right reserved to Landlord at any time to give notice in writing to Tenant of Landlord's election to cancel and terminate this Lease, and the giving of such notice in writing to Tenant of Landlord's election to cancel and terminate this Lease and the simultaneous payment by Landlord to Tenant of any credit balance in Tenant's favor that may at the time be owing to Tenant shall constitute a final and effective cancellation and termination of the Lease and the obligation hereunder on the part of either party to the other. 17. Confession of Judgment. ---------------------- 18. Hold Over. If Tenant shall remain in possession of the Leased --------- Premises after the expiration of the term of this Lease with the prior written consent of Landlord, then Tenant shall be deemed a tenant of the Leased Premises from month to month at the same rental and subject to all of the terms and provisions hereof, except only as to the term of this Lease. 19. Quiet Enjoyment. If Tenant pays rental and other charges herein --------------- provided and shall perform all of the covenants and agreements herein stipulated to be performed on the Tenant's part, Tenant shall, at all times during the term of this Lease, have the peaceable and quiet enjoyment and possession of the Leased Premises without any manner of hindrance from Landlord or any persons lawfully claiming through Landlord, except as to any portion of the Leased Premises as may be taken under the power of eminent domain. 20. Notices. All notices, demands and requests which may be or are ------- required to be given hereunder shall be given in writing and shall be deemed to have been duly given 9

as of the date of receipt or refusal of mailing if sent by postage prepaid, first class, United States registered or certified mail, return receipt requested or by personal messenger, evidenced by written receipt, to each of the parties at the following places, or to such other places as either party hereto may for itself designate in writing from time to time for the purpose of receiving notices hereunder: THE BUNCHER COMPANY WESCO DISTRIBUTION, INC. c/o Buncher Management Agency, Inc. Commerce Court, Suite 700 5600 Forward Avenue Four Station Square P.O. Box 81930 Pittsburgh, PA 15219 Pittsburgh, PA 15217-0930 Attn: Real Estate Manager 22. Entire Agreement. This Lease constitutes and contains the entire and ---------------- only agreement between the parties, and supersedes and cancels any and all pre- existing agreements and understandings between the parties relating to the subject matter hereof. No representation, inducement, promise, condition or warranty not set forth herein has been made or relied upon by either party. 23. Subordination. This Lease is subject and subordinate to all ground ------------- or underlying leases and to all mortgages which may now or hereafter affect the Leased Premises, and to all renewals, modifications, consolidations, replacements and extensions thereof. This clause shall be self-operative and no further instrument of subordination shall be required; however, in confirmation of such subordination Tenant shall execute promptly any certificate to that effect upon reasonable request by Landlord. 24. Limitation of Landlord. Notwithstanding the provisions hereof, the ---------------------- term "Landlord" as used in this Lease means only the holder, for the time being, of Landlord's interest under this Lease so that in the event of any transfer of title to the Leased Premises to a party assuming Landlord's obligations hereunder Landlord shall be and hereby is entirely freed and relieved of all obligations of Landlord hereunder accruing after such transfer, and it shall be deemed without further agreement between the parties that such grantee, transferee or assignee has assumed and agreed to observe and perform all obligations of Landlord hereunder arising during the period it is the holder of Landlord's interest hereunder. 25. Force Majeure. Landlord shall not be liable to Tenant and shall not ------------- be in default under this Lease in any manner by reason of delay in performance of any covenant or condition in this Lease, if any such delay is caused by present or future governmental 10

regulations, restrictions, strikes, lockouts, unusual unavailability of materials or labor, severe adverse weather conditions, or by any other reason or reasons, whether similar or not to foregoing, which delays are beyond the reasonable control of Landlord, provided that Landlord shall use Landlord's best efforts to overcome the same. 26. Attachments. Attached to this Lease and made a part hereof, and ----------- initialed on behalf of both parties simultaneously with the execution of this Lease, are Exhibits A through C inclusive, and Rider pages 1 through 10 inclusive. 27. Governing Law. This Lease shall be construed, governed and enforced ------------- in accordance with the laws of the Commonwealth of Pennsylvania. 28. Separability. If any term or provision of this Lease, or the ------------ application thereof to any party or circumstance, shall to any extent be invalid or unenforceable, the remainder of this Lease, or the application of such term or provision to parties or circumstances other than those as to which it is invalid or unenforceable, shall not be affected thereby, and each term and provision of this Lease shall be valid and be enforced to the fullest extent permitted by law. 29. Cumulative Remedies. The specified remedies to which Landlord or ------------------- Tenant may resort under the terms of this Lease are cumulative and are not intended to be exclusive of any other remedies or means of redress to which Landlord or Tenant may be lawfully entitled in case of any breach by Landlord or Tenant of any provision of this Lease. Failure of Landlord or Tenant to insist in any one or more cases upon the strict performance of any of the covenants of this Lease shall not be construed as a waiver or a relinquishment for the future of such covenant. A receipt by Landlord of rent with knowledge of the breach of any covenant hereof shall not be deemed a waiver of such breach, and no waiver by Landlord or any provision of this Lease shall be deemed to have been made unless expressed in writing and signed by Landlord. In addition to the other remedies in this Lease provided, Landlord or Tenant shall be entitled to the restraint by injunction of the violation, or attempted or threatened violation, of any of the covenants, conditions or provisions of this Lease. Nothing in this Lease shall give either party the right to terminate this Lease except as otherwise specifically set forth in this Lease. 30. Amendments. This Lease may be amended, modified, renewed, extended, ---------- cancelled or terminated only by a written instrument duly executed by both of the parties hereto. 31. Provisions Construed As Covenants. All the provisions of this Lease, --------------------------------- insofar as they are applicable to either or both of the parties hereto, shall be taken and construed 11

as the covenant or covenants of such party or parties respectively to do or perform the thing or act specified or not to do the act or thing inhibited. 32. Binding Effect. The provisions of this Lease shall be binding upon -------------- and shall inure to the benefit of the parties hereto and their respective successors and assigns; subject, nevertheless, to the restrictions on assignment by Tenant as set forth in section 6 hereof and to the provisions of section 24 hereof. 33. Reservations Roads and Utilities. Landlord reserves for itself and -------------------------------- all tenants, the use of access roads and of utilities, and the right to make additional connections, as Landlord may deem necessary, without unreasonable interference with the operations of Tenant. 34. Acceptance of possession of the Leased Premises or opening the same for business shall be conclusive evidence that the Leased Premises are and were in good order and condition on the Commencement Date. 35. Tenant shall have the non-exclusive right to the use of the fifty (50) foot driveway in the area shaded in green on Exhibit A attached hereto which driveway may be used in common with Landlord, Tenant and other respective tenants, their employees, invitees and business visitors for pedestrian and vehicular traffic.

advance, and Tenant shall as expeditiously as is reasonable under the circumstances remove such of its property as it is required to remove under the provisions of section 12 hereof and shall surrender the Leased Premises to Landlord who may enter upon and repossess the same, and all further liability by Tenant and Landlord hereunder shall thereupon cease. If this Lease is not so canceled and terminated, the provisions of the foregoing paragraphs of section 15 shall control. 16. DEFAULTS AND REMEDIES: If Landlord fails to perform any of the covenants and conditions of this Lease to be kept, observed or performed by Landlord, and such failure shall not have been cured within thirty (30) days after notice and demand, or in the event the default is of such a nature that it cannot be cured within thirty (30) days and Landlord has not taken reasonable steps to cure said default, then, Tenant shall have the right to exercise any and all rights and remedies available to it at law or in equity, including, but not limited to, the right to enjoin a breach or threatened breach of this Lease in a court of competent jurisdiction.

Notwithstanding such subletting and assignment, the Tenant shall remain solidarily liable with such sublessee or assignee for the performance of all the terms and conditions of the present Lease. It is understood and agreed that notwithstanding the terms of Article 1873 of the Civil Code of Quebec any such assignment consented to by the Landlord shall in no way acquit the Tenant of its obligations stipulated in this Lease.

If Tenant fails to make any such repairs within a maximum of Ten (10) days or less if Landlord deems reasonably necessary after notice from Landlord requesting Tenant to do so, provided that such repairs may reasonably be made within the said period, or Tenant has not diligently commenced to pursue same, Landlord may, without prejudice to any other rights or remedies it may have, make such repairs and charge the cost thereof to Tenant. Nothing in this Clause shall be construed to obligate or require Landlord to make any repairs but Landlord shall have the right at any time to make any emergency repairs without notice to Tenant and charge the reasonable cost thereof to Tenant. Any costs chargeable to Tenant hereunder shall be payable within thirty (30) days after receipt of invoice as additional rent and shall bear interest at the rate herein above mentioned. 16.

the date of such destruction or damage and the rent and all other payments for which Tenant is liable under the terms of this Lease shall be apportioned and paid in full to the date of such destruction or damage; in the event that neither Landlord or Tenant so terminate this Lease, the Landlord shall repair the said Building with all reasonable speed and the rent hereby reserved shall abate from the date of the happening of the damage until the damage shall be made good to the extent of enabling Tenant to use and occupy the Leased Premises in Tenant's reasonable opinion; (b) If the damage be such that the portion of the Building hereby leased is wholly unfit for occupancy, or if it is impossible or unsafe to use or occupy it but if in either event the damage, in the reasonable opinion of Landlord's architect, to be given to Tenant within thirty (30) days from the happening of such damage, can be repaired with reasonable diligence within one hundred and twenty (120) days of the happening of such damage, then the rent hereby reserved shall abate from the date of the happening of such damage until the damage shall be made good to the extent of enabling Tenant to use and occupy the Leased Premises and Landlord shall repair the damage with all reasonable speed; (c) If, in the opinion of the Landlord's architect, the damage can be made good, as aforesaid, within one hundred and twenty (120) days of the happening of such destruction or damage and the damage is such that the portion of the Building leased is capable of being partially used for the purposes for which it is hereby leased, then until such damage has been repaired the rent shall abate in the proportion that the part of the portion of the Building leased is rendered unfit for occupancy bears to the whole of the said portion of the Building leased and Landlord shall repair the damage with all reasonable speed. Should any mortgage creditor who may have an interest in any insurance proceeds refuse to permit the use of such proceeds for the repair, replacement, rebuilding and/or restoration as hereinabove provided and for the payment of amounts expended for such purposes, then the Landlord's obligation to repair or rebuild as provided for hereinabove shall cease and shall be null and void and the Lease shall be canceled effective as of the date of the damage, unless, the Landlord, at the Landlord's sole option, chooses to repair or rebuild. 17. IMPROVEMENTS AND ALTERATIONS The Tenant shall not make any alterations or repairs to the Leased Premises, or any other part of the Building, or wires, pipes or other services to be run into the Building without first 14

obtaining the written consent of the Landlord, which consent shall not be unreasonably withheld or delayed. Any amounts owing under the terms of this Article shall be payable on demand as additional rent. However in the event that the Landlord shall grant permission to the Tenant to execute the said work for its own account (which permission shall be reasonably determined by the Landlord), then the said work shall be subject to the following conditions: (i) Tenant shall furnish to Landlord plans and specifications showing in reasonably complete detail the work proposed to be carried out and the estimated cost thereof and Landlord shall approve or reject such plans and specifications within fifteen (15) days after receipt of the same.
