PART I ITEM 1. BUSINESS In this Annual Report on Form 10-K, "WESCO" refers to WESCO International, Inc., and its subsidiaries and its predecessors unless the context otherwise requires. References to "we," "us," "our" and the "Company" refer to WESCO and its subsidiaries. Our subsidiaries include WESCO Distribution, Inc. ("WESCO Distribution") and WESCO Distribution Canada, Inc. ("WESCO Canada"), both of which are wholly-owned by WESCO. THE COMPANY With sales of almost $3.7 billion in 2001, we are a leading North American provider of electrical construction products and electrical and industrial maintenance, repair and operating supplies, commonly referred to as "MRO." We are the second largest distributor in the estimated $73 billion U.S. electrical distribution industry, and the largest provider of integrated supply services. Our integrated supply solutions and outsourcing services are designed to fulfill a customer's industrial MRO procurement needs through a highly automated, proprietary electronic procurement and inventory replenishment system. This allows our customers to consolidate suppliers and reduce their procurement and operating costs. We have over 350 branches and five distribution centers located in 48 states, nine Canadian provinces, Puerto Rico, Mexico, Guam, the United Kingdom, Nigeria, Singapore and Venezuela. We serve over 100,000 customers worldwide, offering over 1,000,000 products from over 24,000 suppliers. Our diverse customer base includes a wide variety of industrial companies; contractors for industrial, commercial and residential projects; utility companies; and commercial, institutional and governmental customers. Our leading market positions, extensive geographic reach, broad product and service offerings and acquisition program have enabled us to significantly increase our net sales and improve our financial performance. We have acquired 25 companies since August 1995, representing annual sales of approximately $1.4 billion. Our internal growth, combined with acquisitions, have increased our net sales and earnings before interest, taxes, depreciation, amortization and restructuring charges at compounded annual growth rates of 12% and 23%, respectively, between 1994 and 2001. INDUSTRY OVERVIEW The electrical distribution industry serves customers in a number of markets including the industrial, commercial, construction and utility markets. Electrical distributors, such as us, 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. This distribution channel enables customers to efficiently access a broad range of products and has the capacity to deliver value-added services. Customers are increasingly demanding that distributors provide a broader and more complex package of services as they seek to outsource non-core functions and achieve documented cost savings in purchasing, inventory and supply chain management. ELECTRICAL DISTRIBUTION. The U.S. electrical distribution industry had sales of approximately $73 billion in 2001. While overall weakness in the current economic environment has contributed to recent sales declines, industry growth has averaged 6% per year from 1985 to 2001. This expansion has been driven by general economic growth, increased use of electrical products in businesses and industries, new products and technologies, and customers who are seeking to more efficiently purchase a broad range of products and services from a single point of contact, thereby eliminating the costs and expenses of purchasing directly from manufacturers or multiple sources. The U.S. electrical distribution industry is also highly fragmented. The four national distributors, including WESCO, account for less than 20% of estimated total industry sales. INTEGRATED SUPPLY. The market for integrated supply services has more than doubled from $5 billion in 1997 to over $10 billion in 2000, an increase of 27% per year. Recent projections estimate that the integrated supply market will reach $18.4 billion by 2004. Growth is being driven by the desire of large industrial companies to reduce operating expenses by implementing comprehensive third-party programs, which outsource the cost-intensive procurement, stocking and administrative functions associated with the purchase and consumption of MRO supplies. For our customers, these costs can account for over 50% of the total costs for MRO products and services. The total potential in the United States for integrated supply services, measured as all purchases of industrial MRO supplies and services, is currently estimated to be approximately $260 billion. 2

COMPETITIVE STRENGTHS MARKET LEADERSHIP. Our ability to manage large construction projects and complex multi-site plant maintenance programs and procurement projects that require special sourcing, technical advice, logistical support and locally based service has enabled us to establish leadership positions in our principal markets. We have utilized these skills to generate significant revenues in industries with intensive use of electrical and MRO products, including: electrical contracting, utilities, original equipment manufacturing, process manufacturing and other commercial, institutional and governmental entities. We have also been able to extend our position within these industries to expand our customer base. VALUE-ADDED SERVICES. We are a leader in providing a wide range of services and procurement solutions that draw on our product knowledge, supply and logistics expertise and systems capabilities, enabling our customers to reduce supply chain costs and improve efficiency. These programs include: - National Accounts -- we coordinate product supply and materials management activities for MRO supplies for customers with multiple locations who seek purchasing leverage through a single electrical products provider; - Integrated Supply -- we design and implement programs that enable our customers to significantly reduce the number of MRO suppliers they use through services that include highly automated, proprietary electronic procurement and inventory replenishment systems and on-site materials management and logistics services; and - Major Projects -- we have a dedicated team of experienced construction management personnel to service the needs of the top engineering and construction firms which specialize in major projects such as airport expansions, stadiums and healthcare facilities. BROAD PRODUCT OFFERING. We provide our customers with a broad product selection consisting of over 1,000,000 electrical, industrial and data communications products sourced from over 24,000 suppliers. Our broad product offering enables us to meet virtually all of a customer's electrical product and other MRO requirements. EXTENSIVE DISTRIBUTION NETWORK. Our distribution network consists of over 350 branches and five distribution centers located in 48 states, nine Canadian provinces, Puerto Rico, Mexico, Guam, the United Kingdom, Nigeria, Singapore and Venezuela. This extensive network, which would be extremely difficult and expensive to duplicate, allows us to: - maintain local customer service, technical support, and sales coverage; - tailor branch products and services to local customer needs; - offer multi-site distribution capabilities to large customers and national accounts; and - provide same-day deliveries. LOW COST OPERATOR. Our competitive position has been enhanced by our low cost position, which is based on: - extensive use of automation and technology; - centralization of functions such as purchasing and accounting; - strategically located distribution centers; - purchasing economies of scale; and - incentive programs that increase productivity and encourage entrepreneurship. Our low cost position enables us to generate a significant amount of cash flow as the capital investment required to maintain our business is low. This cash flow is available for debt reduction, strategic acquisitions and continued 3

investment in the growth of the business. BUSINESS STRATEGY Our objective is to be the leading provider of electrical products and other MRO supplies and services to companies in North America and selected international markets. In achieving this leadership position, our goal is to grow earnings at a faster rate than sales by focusing on margin enhancement and continuous productivity improvement. Our growth strategy leverages our existing strengths and focuses on developing new initiatives and programs. ENHANCE OUR LEADERSHIP POSITION IN ELECTRICAL DISTRIBUTION. We intend to leverage our extensive market presence and brand equity in the WESCO name to further our leadership position in electrical distribution. We are focusing our sales and marketing on existing industries where we are expanding our product and service offerings as well as targeting new clients, both within industries we currently serve and in new markets which provide significant growth opportunities. Markets where we believe such opportunities exist include retail, education, financial services and health care. We are the second largest electrical distributor in the United States and, through our value-added products and services, we believe we have become the industry leader in serving several important and growing markets including: - industrial customers with large, complex plant maintenance operations, many of which require a national multi-site service solution for their electrical distribution product needs; - large contractors for major industrial and commercial construction projects; - the electric utility industry; and - manufacturers of factory-built homes, recreational vehicles and other modular structures. GROW NATIONAL ACCOUNTS PROGRAMS. From 1994 through 2001, revenue from our national accounts program increased in excess of 11% annually. We will continue to invest in the expansion of this program. Through our national accounts program, we coordinate electrical MRO procurement and purchasing activities primarily for large industrial and commercial companies across multiple locations. We have well-established relationships with over 300 companies, providing us with a recurring base of revenue through multi-year agreements. Our objective is to continue to increase revenue generated through our national accounts program by: - offering existing national account customers new products, more services and additional locations; - extending certain established national account relationships to include integrated supply; and - expanding our customer base by leveraging our existing industry expertise in markets we currently serve as well as entering into new markets. FOCUS ON MAJOR PROJECTS. We are increasing our focus on large construction, renovation and institutional projects. We seek to secure new major projects contracts through: - active national marketing of our demonstrated project management capabilities; - further development of relationships with leading regional and national contractors and engineering firms; - close coordination with national account customers on their major project requirements; and 4

- offering an integrated supply service approach to contractors for major projects. EXTEND OUR LEADERSHIP POSITION IN INTEGRATED SUPPLY. We are the largest provider of integrated supply services for MRO goods and services in the United States. We provide a full complement of outsourcing solutions, focusing on improving the supply chain management process for our customers' indirect purchases. Our integrated supply programs replace the traditional multi-vendor, resource-intensive procurement process with a single, outsourced, fully automated process capable of managing all MRO and related service requirements. Our solutions range from timely product delivery to assuming full responsibility for the entire procurement function. Our customers include some of the largest industrial companies in the United States. We intend to expand our leadership position as the largest integrated supply service provider by: - continuing to tailor our proven and profitable business model to the scale and scope of our customers' operations; - maximizing the use of our highly automated proprietary information systems; - leveraging established relationships with our large industrial customer base, especially among existing national account customers who could benefit from our integrated supply model; and - being a low cost provider of integrated supply services. We intend to utilize these competitive strengths to increase our integrated supply sales to both new and existing customers, including our existing national account customers. GAIN SHARE IN KEY LOCAL MARKETS. Significant opportunities exist to gain local market share, since many local markets are highly fragmented. We intend to increase our market share in key geographic markets through a combination of increased sales and marketing efforts at existing branches, acquisitions that expand our product and customer base and new branch openings. We intend to leverage our existing relationships with preferred suppliers to increase sales of their products in local markets through various initiatives, including sales promotions, cooperative marketing efforts, direct participation by suppliers in national accounts implementation, dedicated sales forces and product exclusivity. To promote growth, we have instituted a compensation system for branch managers that encourages our branch managers to increase sales and optimize business activities in their local markets, including managing the sales force, configuring inventories, targeting potential customers for marketing efforts and tailoring local service options. PURSUE STRATEGIC ACQUISITIONS. Since 1995, we have considered over 300 potential acquisitions and have completed and successfully integrated 25 acquisitions, which represent annual sales of approximately $1.4 billion. We believe that the highly fragmented nature of the electrical and industrial MRO distribution industry will continue to provide us with acquisition opportunities. In our disciplined approach toward acquisitions, potential acquisitions are evaluated based on a variety of financial, strategic and operational criteria, including their ability to: - better serve our existing customers; - offer expansion into key growth markets; - add new product or service capabilities; - support new and existing national accounts; - strengthen relationships with important manufacturers; and - meet well-defined financial criteria including return on investment and earnings accretion. EXPAND PRODUCT AND SERVICE OFFERINGS. We continue to build on our demonstrated ability to introduce new products and services to meet existing customer demands and capitalize on new market opportunities. As the market for data and electrical products converge, we have integrated our data communications efforts into our core electrical business. Our existing electrical sales force has been trained to sell data communications products resulting in significant new data and electrical projects with large commercial banks, schools and 5

telecommunications service providers. In addition, we have the platform to sell integrated lighting control and power distribution equipment in a single package for multi-site specialty retailers, restaurant chains and department stores. These are strong growth markets where our national accounts strategies and logistics infrastructure provide significant benefits for our customers. LEVERAGE OUR E-COMMERCE AND INFORMATION SYSTEM CAPABILITIES. We conduct a significant amount of business electronically. Our electronic transaction management capabilities lower costs and shorten cycle time in the supply chain process for us and for our customers. We intend to continue to invest in information technology to create more effective linkages with both customers and suppliers. EXPAND OUR INTERNATIONAL OPERATIONS. Our international sales, the majority of which are in Canada, accounted for approximately 11% of sales in 2001. We believe that there is significant additional demand for our products and services outside the United States and Canada. Many of our multinational domestic customers are seeking distribution, integrated supply and project management solutions globally. Our approach to international operations is consistent with our domestic philosophy. We follow our established customers and pursue business that we believe utilizes and extends our existing capabilities. This strategy of working through well-developed customer and supplier relationships significantly reduces risks and provides the opportunity to establish a profitable business. We have five locations in Mexico headquartered in Tlalnepantla that serve all of metropolitan Mexico City and the Federal District and the states of Mexico, Morelos and Hidalgo. We continue to pursue growth opportunities in existing locations such as Aberdeen, Scotland; London, England, which support our sales efforts in Europe and the former Soviet Union. We have an operation in Nigeria to serve West Africa, an office in Caracas, Venezuela to serve the Northern portion of South America and an office in Singapore to support our sales to customers in Asia. We are working toward forming strategic alliances in critical markets, where appropriate. ACQUISITION AND INTEGRATION PROGRAM Our strategic acquisition program has been an important element in our objective to be the leader in the markets we serve. We have completed 25 acquisitions since August 1995, representing total annual sales of approximately $1.4 billion. Our philosophy toward growth includes a continuous evaluation to determine whether a particular opportunity, capability or customer need is best developed internally or purchased through a strategic acquisition. We have a business development department that consists of a small team of professionals who locate, evaluate and negotiate all aspects of any acquisition, with particular emphasis on compatibility of management philosophy and strategic fit. We believe that the highly fragmented nature of the electrical distribution industry will continue to provide us with acquisition opportunities. We will continue to utilize our strong internal capabilities to selectively evaluate the strategic and financial benefits from potential acquisitions that complement our customers' overall supply needs, including those in the electrical distribution, integrated supply and other non-electrical distribution industries. The Company expects that future acquisitions will be financed out of available internally generated funds, additional debt and the issuance of equity securities. However, our ability to make acquisitions will be subject to our compliance with certain conditions under the terms of our new revolving credit facility. See Part II, Item 7. - "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Liquidity and Capital Resources" for a further description of the new revolving credit facility. 6

PRODUCTS AND SERVICES Products Our network of branches and distribution centers stock over 215,000 product stock keeping units ("SKUs"). Each branch tailors its inventory to meet the needs of the customers in its local market, typically stocking approximately 4,000 to 8,000 SKUs. Our integrated supply business allows our customers to access over 1,000,000 products for direct shipment. Representative products that we sell include: - Electrical Supplies. Fuses, terminals, connectors, boxes, fittings, tools, lugs, tape and other MRO supplies. - Industrial Supplies. Cutting and other tools, abrasives, filters and safety equipment. - Distribution. Circuit breakers, transformers, switchboards, panelboards and busway. - Lighting. Lamps, fixtures and ballasts. - Wire and Conduit. Wire, cable, metallic and non-metallic conduit. - Control, Automation and Motors. Motor control devices, drives, programmable logic controllers, pushbuttons and operator interfaces. - Data Communications. Premise wiring, patch panels, terminals and connectors. We purchase products from a diverse group of over 24,000 suppliers. In 2001, our ten largest suppliers accounted for approximately 34% of our purchases. The largest of these was Eaton Corporation, through its Cutler-Hammer division, accounting for approximately 14% of total purchases. No other supplier accounted for more than 5% of total purchases. Our supplier relationships are important to us, providing access to a wide range of products, technical training and sales and marketing support. We have preferred supplier agreements with approximately 150 of our suppliers and purchase approximately 65% of our stock inventory pursuant to these agreements. Consistent with industry practice, most of our agreements with suppliers, including both distribution agreements and preferred supplier agreements, are terminable by either party on 60 days' notice or less. 7

Services In conjunction with product sales, we offer customers a wide range of services and procurement solutions that draw on our product and supply management expertise and systems capabilities. These services include national accounts programs, integrated supply programs and major project programs. We are responding to the needs of our customers, particularly those in processing and manufacturing industries. To more efficiently manage the MRO process on behalf of our customers, we offer a range of supply management services, including: - outsourcing of the entire MRO purchasing process; - providing technical support for manufacturing process improvements using state-of-the-art automated solutions; - implementing inventory optimization programs; - participating in joint cost savings teams; - assigning our employees as on-site support personnel; - recommending energy-efficient product upgrades; and - offering safety and product training for customer employees. National accounts programs. The typical national account customer is a Fortune 500 industrial company, a large utility or other major customer, in each case with multiple locations. Our national accounts programs are designed to provide customers with total supply chain cost reductions by coordinating purchasing activity for MRO supplies across multiple locations. Comprehensive implementation plans establish jointly managed teams at the local and national level to prioritize activities, identify key performance measures and track progress against objectives. We involve our preferred suppliers early in the implementation process, where they can contribute expertise and product knowledge to accelerate program implementation and the achievement of cost savings and process improvements. Integrated supply programs. Our integrated supply programs offer customers a variety of services to support their objectives for improved supply chain management. We integrate our 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. Our solutions range from just-in-time fulfillment to assuming full responsibility for the entire procurement function for all indirect purchases. We believe that customers will increasingly seek to utilize us as an "integrator," responsible for selecting and managing the supply of a wide range of MRO and OEM products. Major projects. We have a major projects group, comprised of our most experienced construction management personnel, which focuses on serving the complex needs of North America's largest engineering and construction firms and the top 50 U.S. electrical contractors on a multi-regional basis. These contractors typically specialize in building industrial sites, water treatment plants, airport expansions, healthcare facilities, correctional institutions and new sports stadiums. MARKETS AND CUSTOMERS We have a large base of approximately 100,000 customers diversified across our principal markets. While two customers each accounted for almost 3% of 2001 sales, no other customer accounted for more than 2% of 2001 sales. Industrial customers. Sales to industrial customers, which include numerous manufacturing and process industries, and original equipment manufacturers ("OEMs") accounted for approximately 42% of our sales in 2001. MRO products are needed to maintain and upgrade the electrical and communications networks at all industrial sites. Expenditures are greatest in the heavy process industries, such as food processing, pulp and paper and 8

petrochemical. Typically, electrical MRO is the first or second ranked product category by purchase value for total MRO requirements for an industrial site. Other MRO product categories include, among others, lubricants, pipe, valves and fittings, fasteners, cutting tools and power transmission products. OEM customers incorporate electrical components and assemblies into their own products. OEMs typically require a reliable, high volume supply of a narrow range of electrical items. Customers in this segment are particularly service and price sensitive due to the volume and the critical nature of the product used, and they also expect value-added services such as design and technical support, just-in-time supply and electronic commerce. Electrical contractors. Sales to electrical contractors accounted for approximately 35% of our sales in 2001. These customers range from large contractors for major industrial and commercial projects, the customer types we principally serve, to small residential contractors, which represent a small portion of our sales. Electrical products purchased by electrical sub-contractors typically account for approximately 40% to 50% of their installed project cost, and, therefore, accurate cost estimates and competitive material costs are critical to a contractor's success in obtaining profitable projects. Utilities. Sales to utilities accounted for approximately 17% of our sales in 2001. This market includes large investor-owned utilities, rural electric cooperatives and municipal power authorities. We provide our utility customers with power line products and an extensive range of supplies to meet their MRO and capital projects needs. Full materials management and procurement outsourcing arrangements are also important in this market as cost pressures and deregulation cause utility customers to streamline purchasing and inventory control practices. Commercial, institutional and governmental customers ("CIG"). Sales to CIG customers accounted for approximately 6% of our sales in 2001. This fragmented market includes schools, hospitals, property management firms, retailers and government agencies of all types. Through our WR Controls Division, we have a platform to sell integrated lighting control and distribution equipment in a single package for multi-site specialty retailers, restaurant chains and department stores. DISTRIBUTION NETWORK Branch network. We have over 350 branches, of which approximately 290 are located in the United States, approximately 50 are located in Canada and the remainder are located in Puerto Rico, Mexico, Guam, the United Kingdom, Nigeria, Singapore and Venezuela. Over the last three years, we have opened approximately seven branches per year, principally to service national account customers. In addition to consolidations in connection with acquisitions, we occasionally close or consolidate existing branch locations to improve operating efficiency. Distribution centers. To support our branch network, we have five distribution centers located in the United States and Canada, including facilities located near Pittsburgh, Pennsylvania, serving the Northeast and Midwest United States; near Reno, Nevada, serving the Western United States; near Memphis, Tennessee, serving the Southeast and Central United States; near Montreal, Quebec, serving Eastern and Central Canada; and near Vancouver, British Columbia, serving Western Canada. Our distribution centers add value for our branches and customers through the combination of a broad and deep selection of inventory, on-line ordering, same day shipment and central order handling and fulfillment. Our distribution center network reduces the lead-time and improves the reliability of our supply chain, giving us a distinct competitive advantage in customer service. Additionally, the distribution centers reduce the time and cost of supply chain activities through automated replenishment and warehouse management systems, and economies of scale in purchasing, inventory management, administration and transportation. SALES ORGANIZATION General sales force. Our general sales force is based at the local branches and comprises approximately 2,200 of our employees, almost half of whom are outside sales representatives and the remainder are inside sales personnel. Outside sales representatives 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 a key point of contact for responding to routine customer inquiries such as price and availability requests and for entering and tracking orders. 9

National accounts. Our national accounts sales force is comprised of an experienced group of sales executives who negotiate and administer contracts, coordinate branch participation and 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. Sales of premise cable, connectors, hardware, network electronics and outside plant products are generated by our general sales force and a dedicated group of outside and inside data communications sales representatives. They are supported by a centralized customer service center and additional resources in product management, purchasing, inventory control and sales management. Major projects. Since 1995 our group of experienced sales managers have targeted, on a national basis, the market for large construction projects with electrical material valued in excess of $1 million. Through the major projects group, we can meet the needs of contractors for complex construction projects such as new sports stadiums, industrial sites, water treatment plants, airport expansions, healthcare facilities and correctional institutions. e-Commerce. We established our initial electronic catalog on the Internet in 1996. Since that time, we have worked with a variety of large customers to establish customized electronic catalogs for their use in internal systems. Additionally, in 1999 we began a process of providing electronic catalogs to multiple e-commerce service providers, trade exchanges and industry specific electronic commerce portals. Our e-business strategy is to serve existing customers by tailoring our catalog and Internet-based procurement applications to their internal systems or through their preferred technology and trading exchange partnerships. We lead our industry in rapid e-implementation to customers' procurement systems and provide integrated procurement functionality using "punch-out" technology, a direct system to system link with our customers. We continue to enhance "WESCOExpress," a new direct ship fulfillment operation, responsible for supporting smaller customers and select national account locations. Customers can order over 65,000 electrical and data communications products stocked in our warehouses through a centralized customer service center or over the Internet on WESCOdirect.com. We use a proactive telesales approach utilizing catalogs, direct mail, e-mail and personal phone selling to provide a high level of customer service. In support of this initiative, we recently introduced the WESCO Electrical Buyers Guide (TM), a comprehensive electrical catalog containing over 24,000 products from the top 150 manufacturers in the electrical industry. INTERNATIONAL OPERATIONS To serve the Canadian market, we operate 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$311 million, Canada represented 8.5% of our total sales in 2001. The Canadian market for electrical distribution is considerably smaller than the U.S. market, with roughly US$3.0 billion in total sales in 2001, according to industry sources. We also have five locations in Mexico headquartered in Tlalnepantla, that serve all of metropolitan Mexico City and the Federal District and the states of Mexico, Morelos and Hidalgo. We sell internationally through domestic export sales offices located within North America and sales offices in international locations. WESCO operations are in Aberdeen, Scotland and London, England to support sales efforts in Europe and the former Soviet Union. We have an operation in Nigeria to serve West Africa, an office in Caracas, Venezuela to serve the Northern portion of South America and an office in Singapore to support our sales to Asia. All of the international locations have been established to primarily serve WESCO's growing list of customers with global operations referenced under National Accounts above. 10

MANAGEMENT INFORMATION SYSTEMS Our corporate information system, WESNET, provides processing for a full range of our business operations, such as customer service, inventory and logistics management, accounting and administrative support. The system utilizes decision support, executive information system analysis and retrieval capabilities to provide extensive operational analysis and detailed income statement and balance sheet variance and trend reporting at the branch level. The system also provides activity-based costing capabilities for analyzing profitability by customer, sales representative and shipment type. Sales and margin trends and variances can be analyzed by branch, customer, product category, supplier or account representative. The WESNET system operates as a distributed network of fully functional operating units, and every branch (other than our Bruckner Integrated Supply Division and certain newly acquired branches) utilizes its own computer system to support local business activities. All branch operations are linked through a wide area network to centralized information on inventory status in our distribution centers as well as other branches and an increasing number of on-line suppliers. Recent advances in WESNET capabilities make it possible to consolidate administrative and procurement functions, and bring systematic improvement through new pricing systems and controls. We routinely process customer orders, shipping notices, suppliers' purchase orders, and funds transfer via EDI transactions with our trading partners. Our e-Commerce strategy calls for more effective linkages to both customers and suppliers through greater use of technological advances, including Internet and electronic catalogs, enhanced EDI and other innovative improvements. Our integrated supply services are supported by our proprietary procurement and inventory management systems. These systems provide a fully integrated, flexible supply chain platform that currently handles over 95% of our integrated supply customers' transactions electronically. Our configuration options for a customer range from on-line linkages to the customer's business and purchasing systems, to total replacement of a customer's procurement and inventory management system for MRO supplies. COMPETITION We operate in a highly competitive industry. We compete directly with national, regional and local providers of electrical and other industrial MRO supplies. Competition is primarily focused on the local service area, and is generally based on product line breadth, product availability, service capabilities and price. Another source of competition is buying groups formed by smaller distributors to increase purchasing power and provide some cooperative marketing capability. While increased buying power may improve the competitive position of buying groups locally, we believe these groups have not been able to compete effectively with us for national account customers due to the difficulty in coordinating a diverse ownership group. During 1999 and 2000 numerous special purpose Internet-based procurement service companies, auction businesses, and trade exchanges were organized. Many of them targeted industrial MRO and contractor customers of the type served by WESCO. We responded with our own e-Commerce capabilities and as of year-end 2000, business losses, if any, to competitors of this type were minimal. We expect that numerous new competitors will develop over time as Internet-based enterprises become more established and refine their service capabilities. EMPLOYEES As of December 31, 2001, we had approximately 5,700 employees worldwide, of which approximately 5,000 were located in the United States and approximately 700 in Canada and our other international locations. Less than 5% of our employees are represented by unions. We believe our labor relations are generally good. INTELLECTUAL PROPERTY Our trade and service marks, including "WESCO," "the extra effort people(R)," and the running man design, are filed in the U.S. Patent and Trademark Office, the Canadian Trademark Office and the Mexican Instituto de la Propriedad Industrial. 11

ENVIRONMENTAL MATTERS Our facilities and operations are subject to federal, state and local laws and regulations relating to environmental protection and human health and safety. Some 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. These persons may include former, current or future owners or operators of properties, and persons who arranged for the disposal of hazardous substances. Our owned and leased real property may give rise to such investigation, remediation and monitoring liabilities under environmental laws. In addition, anyone disposing of certain products we distribute, such as ballasts, fluorescent lighting and batteries, must comply with environmental laws that regulate certain materials in these products. We believe that we are in compliance with all material respects with applicable environmental laws. As a result, we will not make significant capital expenditures for environmental control matters either in the current year or in the near future. FORWARD LOOKING INFORMATION This Annual Report on Form 10-K contains various "forward looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. These statements involve certain unknown risks and uncertainties, including, among others, those contained in Item 1, "Business" and Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations." When used in this Annual Report on Form 10-K, the words "anticipates," "plans," "believes," "estimates," "intends," "expects," "projects" and similar expressions may identify forward looking statements, although not all forward looking statements contain such words. Such statements, including, but not limited to, our statements regarding business strategy, growth strategy, productivity and profitability enhancement, competition, 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, some of which are beyond our control. Our actual results could differ materially from those expressed in any forward looking statement made by or on our behalf. In light of these risks and uncertainties, there can be no assurance that the forward looking information will in fact prove to be accurate. We have undertaken no obligation to publicly update or revise any forward looking statements, whether as a result of new information, future events or otherwise. Important factors that could cause actual results to differ materially from the forward looking statements we make are described below. All forward looking statements attributable to us or persons working on our behalf are expressly qualified by the following cautionary statements: OUR SUBSTANTIAL AMOUNT OF DEBT REQUIRES SUBSTANTIAL DEBT SERVICE OBLIGATIONS THAT COULD ADVERSELY AFFECT OUR ABILITY TO FULFILL OUR OBLIGATIONS AND COULD LIMIT OUR GROWTH AND IMPOSE RESTRICTIONS ON OUR BUSINESS. We are and will continue to be significantly leveraged. As of December 31, 2001, we had $452.0 million of consolidated indebtedness and stockholders' equity of $144.7 million. We and our subsidiaries may incur additional indebtedness in the future, subject to certain limitations contained in the instruments governing our indebtedness. Accordingly, we will have significant debt service obligations. These amounts exclude WESCO's accounts receivable securitization program, through which WESCO sells accounts receivable to a third party conduit and removes these receivables from its consolidated balance sheet. See Part II, Item 7.-"Management's Discussion and Analysis of Financial Condition and Results of Operations-Critical Accounting Policies." Our debt service obligations have important consequences, including the following: - a substantial portion of cash flow from our operations will be dedicated to the payment of principal and interest on our indebtedness, thereby reducing the funds available for operations, future business opportunities and acquisitions and other purposes and increasing our vulnerability to adverse general economic and industry conditions; - our ability to obtain additional financing in the future may be limited; - approximately $169 million of our indebtedness is at variable rates of interest, which will make us vulnerable to increases in interest rates; 12

- we will be substantially more leveraged than certain of our competitors, which might place us at a competitive disadvantage; and - we may be hindered in our ability to adjust rapidly to changing market conditions. Our ability to make scheduled payments of the principal of, or to pay interest on, or to refinance our indebtedness and to make scheduled payments under our operating leases or to fund planned capital expenditures or finance acquisitions will depend on our future performance, which to a certain extent is subject to economic, financial, competitive and other factors beyond our control. There can be no assurance that our business will continue to generate sufficient cash flow from operations in the future to service our debt, make necessary capital expenditures or meet other cash needs. If unable to do so, we may be required to refinance all or a portion of our existing debt, to sell assets or to obtain additional financing. There can be no assurance that any such refinancing or that any such sale of assets or additional financing would be possible on terms reasonably favorable to us. See Part II - Item 7. - "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Liquidity and Capital Resources." RESTRICTIVE DEBT COVENANTS CONTAINED IN OUR REVOLVING CREDIT FACILITY AND THE INDENTURE TO OUR SENIOR SUBORDINATED NOTES TO TAKE CERTAIN ACTIONS. The revolving credit facility and the indenture contain numerous financial and operating covenants that will limit the discretion of our management with respect to certain business matters. These covenants place significant restrictions on the ability of us and our subsidiaries. to: - incur additional indebtedness; - pay dividends and other distributions; - enter into sale and leaseback transactions; - create liens or other encumbrances; - make certain payments and investments; - engage in certain transactions with affiliates; - make certain acquisitions; - sell or otherwise dispose of assets; and - merge or consolidate with other entities, and will otherwise restrict corporate activities. The revolving credit facility also requires us to meet certain financial ratios and tests. Our ability to comply with these and other provisions of the revolving credit facility and the indenture may be affected by changes in economic or business conditions or other events beyond our control. A failure to comply with the obligations contained in the revolving credit facility or the indenture could result in an event of default under either the revolving credit facility or the indenture which could result in acceleration of the related debt and the acceleration of debt under other instruments evidencing indebtedness that may contain cross-acceleration or cross-default provisions. If the indebtedness under the revolving credit facility were to be accelerated, there can be no assurance that our assets would be sufficient to repay in full such indebtedness and our other indebtedness. See Part II - Item 7. - "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Liquidity and Capital Resources." 13

DOWNTURNS IN THE ELECTRICAL DISTRIBUTION INDUSTRY HAVE HAD IN THE PAST, AND MAY IN THE FUTURE HAVE, AN ADVERSE EFFECT ON OUR SALES AND PROFITABILITY. The electrical distribution industry is affected by changes in economic conditions, including national, regional and local slowdowns in construction and industrial activity, which are outside our control. Our 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 under the revolving credit facility. In addition, during periods of economic slowdown such as the one we are currently experiencing, our credit losses increase. There can be no assurance that economic slowdowns, adverse economic conditions or cyclical trends in certain customer markets will not have a material adverse effect on our operating results and financial condition. AN INCREASE IN COMPETITION COULD DECREASE SALES OR EARNINGS. We operate in a highly competitive industry. We compete directly with national, regional and local providers of electrical and other industrial MRO supplies. Competition is primarily focused in the local service area and is generally based on product line breadth, product availability, service capabilities and price. Other sources of competition are buying groups formed by smaller distributors to increase purchasing power and provide some cooperative marketing capability. During 1999 and 2000 numerous special purpose Internet-based procurement service companies, auction businesses and trade exchanges were organized. Many of them targeted industrial MRO and contractor customers of the type served by us. We expect that numerous new competitors will develop over time as Internet-based enterprises become more established and refine their service capabilities. Some of our existing competitors have, and new market entrants may have, greater financial and marketing resources than we do. To the extent existing or future competitors seek to gain or retain market share by reducing prices, we may be required to lower our prices, thereby adversely affecting financial results. Existing or future competitors also may seek to compete with us for acquisitions, which could have the effect of increasing the price and reducing the number of suitable acquisitions. In addition, it is possible that competitive pressures resulting from the industry trend toward consolidation could affect growth and profit margins. SUCCESS OF OUR GROWTH STRATEGY MAY BE LIMITED BY THE AVAILABILITY OF APPROPRIATE ACQUISITIONS AND OUR ABILITY TO INTEGRATE ACQUIRED COMPANIES INTO OUR BUSINESS. A component of our growth strategy is to continue to expand through additional acquisitions that complement our operations in new or existing markets. Our acquisitions will involve risks, including the successful integration and management of acquired operations and personnel. The integration of acquired businesses may also lead to the loss of key employees of the acquired companies and diversion of management attention from ongoing business concerns. We may not be able to identify businesses that meet our strategic criteria and acquire them on satisfactory terms. We also may not have access to sufficient capital to complete certain acquisitions, and we will be constrained by restrictions in our revolving credit facility. Future acquisitions may not prove advantageous and could have a material adverse effect on our operating results. See Part II, Item 7. - "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Liquidity and Capital Resources." LOSS OF KEY SUPPLIERS OR LACK OF PRODUCT AVAILABILITY COULD DECREASE SALES AND EARNINGS. Most of our agreements with suppliers are terminable by either party on 60 days' notice or less. Our ten largest suppliers in 2001 accounted for approximately 34% of our purchases for the period. Our largest supplier was Eaton Corporation, through its Cutler-Hammer division, accounting for approximately 14% of our 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 our business. In addition, supply interruptions could arise from shortages of raw materials, labor disputes or weather conditions affecting products or shipments, transportation disruptions, or other reasons beyond our control. An interruption of operations at any of our five distribution centers could have a material adverse effect on the operations of branches served by the affected distribution center. Furthermore, we cannot be certain that particular products or product lines will be available to us, or available in quantities sufficient to meet customer demand. Such limited product access could put us at a competitive disadvantage. 14

A DISRUPTION OF OUR INFORMATION SYSTEMS COULD INCREASE EXPENSES, DECREASE SALES OR REDUCE EARNINGS. A serious disruption of our information systems could have a material adverse effect on our business and results of operations. Our computer systems are an integral part of our business and growth strategies. We depend on our information systems to process orders, manage inventory and accounts receivable collections, purchase products, ship products to our customers on a timely basis, maintain cost-effective operations and provide superior service to our customers. WESCO INTERNATIONAL'S CONTROLLING SHAREHOLDERS OWN APPROXIMATELY 44% OF ITS COMMON STOCK AND CAN EXERCISE SIGNIFICANT INFLUENCE OVER OUR AFFAIRS. Approximately 44% of the issued and outstanding shares of common stock of WESCO International is held by Cypress and its affiliates. Accordingly, Cypress and its affiliates can exercise significant influence over our affairs, including the election of our directors, appointment of our management and approval of actions requiring the approval of our stockholders, including the adoption of amendments to our certificate of incorporation and approval of mergers or sales of substantially all of our assets. ITEM 2. PROPERTIES. We have over 350 branches, of which approximately 290 are located in the United States, approximately 50 are located in Canada and the remainder are located in Puerto Rico, Mexico, Guam, the United Kingdom, Nigeria, Singapore and Venezuela. Approximately 25% of branches are owned facilities, and the remainder are leased. The following table summarizes our distribution centers: LOCATION SQUARE FEET LEASED/OWNED ------------------------------------------------------------------------- Warrendale, PA..................... 252,700 Owned and Leased Sparks, NV......................... 196,800 Leased Byhalia, MS........................ 148,000 Owned Dorval, QE......................... 90,000 Leased Burnaby, BC........................ 64,865 Owned We also lease our 76,200 square foot headquarters in Pittsburgh, Pennsylvania. We do not regard the real property associated with any single branch location as material to our operations. We believe our facilities are in good operating condition. ITEM 3. LEGAL PROCEEDINGS. We are party to routine litigation incidental to our business. We do not believe that any legal proceedings to which we are a party or to which any of our property is subject will have a material adverse effect on our financial position or results of operations. ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS. No matters were submitted to a vote of the Company's security holders during the fourth quarter of 2001. 15

PART II ITEM 5. MARKET FOR REGISTRANT'S COMMON STOCK AND RELATED STOCKHOLDER MATTERS. On May 17, 1999, WESCO completed its initial public offering of common stock ("the Offering"), which is listed on the New York Stock Exchange under the symbol "WCC." As of February 28, 2002, there were 40,237,162 shares of common stock and 4,653,131 shares of Class B common stock outstanding held by approximately 100 holders of record. We have not paid dividends on the common stock, and do not presently plan to pay dividends in the foreseeable future. It is currently expected that earnings will be retained and reinvested to support either business growth or debt reduction. See Part II, Item 7. - "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Liquidity and Capital Resources." The following table sets forth the high and low sales price of the shares for the periods indicated. SALES PRICES ------------------------- QUARTER HIGH LOW ------------------------------------------------- 2001 First $11.00 $7.06 Second 9.25 7.30 Third 9.20 4.65 Fourth 6.50 3.95 2000 First $ 9.00 $7.06 Second 10.88 7.75 Third 10.13 7.50 Fourth 9.88 7.31 In connection with the Initial Public Offering, the Board of Directors approved a 57.8 to one stock split effected in the form of a stock dividend of WESCO's common stock. The Board of Directors also reclassified the Class A common stock into common stock, increased the authorized common stock to 210,000,000 shares and the authorized Class B common stock to 20,000,000 shares and authorized 20,000,000 shares of $.01 par value preferred stock, all effective May 11, 1999. In May 2000, WESCO's board of directors authorized an additional $25 million to be added to its existing $25 million share repurchase program which was authorized in November 1999. WESCO's common stock may be purchased at management's discretion, subject to certain financial ratios, in open market transactions and the program may be discontinued at any time. As of February 28, 2002, WESCO had purchased approximately 3.9 million shares of its common stock for approximately $32.8 million pursuant to this program. In August 2001, WESCO Distribution entered into an amendment to its revolving credit facility, which, among other things, prohibited WESCO from repurchasing additional shares of its common stock. In March 2002, WESCO entered into a new revolving credit agreement, the proceeds of which, were used to retire its then existing credit facility. The new credit agreement permits WESCO to repurchase shares of its common stock, assuming the Company meets or exceeds certain financial ratios. 17

(7) EBITDA before recapitalization and restructuring charges represents income from operations plus depreciation, amortization, recapitalization and restructuring costs. EBITDA before recapitalization and restructuring charges is presented since management believes that such information is considered by certain investors to be an additional basis for evaluating the Company's ability to pay interest and repay debt. EBITDA should not be considered an alternative to measures of operating performance as determined in accordance with generally accepted accounting principles or as a measure of the Company's operating results and cash flows or as a measure of the Company's liquidity. Since EBITDA is not calculated identically by all companies, the presentation herein may not be comparable to other similarly titled measures of other companies. (8) Represents redeemable common stock as described in Note 10 to the Consolidated Financial Statements. 18

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS. The following discussion should be read in conjunction with the audited consolidated financial statements and notes thereto included elsewhere in this Annual Report on Form 10-K. GENERAL WESCO's sales can be categorized as stock, direct ship and special order. Stock orders are filled directly from existing inventory and generally represent 40% to 45% of total sales. Approximately 42% to 48% of WESCO's total sales are direct ship sales. Direct ship sales are typically custom-built products, large orders or products that are too bulky to be easily handled and, as a result, are shipped directly to the customer from the supplier. Special orders are for products that are not ordinarily stocked in inventory and are ordered based on a customer's specific 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 gross margins are lower, operating profit margins are often comparable, since the product handling and fulfillment costs associated with direct shipments are much lower. WESCO has historically financed its working capital needs, capital expenditures, acquisitions and new branch openings through internally generated cash flow and borrowings under its credit facilities and its accounts receivable securitization program. During the initial phase of an acquisition or new branch opening, WESCO typically incurs expenses related to installing or converting information systems, training employees and other initial operating activities. With some acquisitions, WESCO 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. WESCO has accounted for its acquisitions under the purchase method of accounting. WESCO is a leading consolidator in its industry, having acquired 25 companies since August 1995, representing annual sales of approximately $1.4 billion. Management distinguishes sales attributable to core operations separately from sales of acquired businesses. The distinction between sales from core operations and from acquired businesses is based on the Company's internal records and on management estimates where the integration of acquired businesses results in the closing or consolidation of branches. However, "core operations" typically refer to all internally started branches and all acquired branches that have been in operation for the entire current and prior year-to-date periods. "Acquired businesses" generally refer to branch operations purchased by WESCO where the branches have not been under WESCO ownership for the entire current and prior year-to-date periods. CRITICAL ACCOUNTING POLICIES AND ESTIMATES WESCO's discussion and analysis of its financial condition and results of operations are based upon WESCO's consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires WESCO to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, WESCO evaluates its estimates, including those related to supplier programs, bad debts, inventories, goodwill, income taxes, restructuring cost, contingencies and litigation. WESCO bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. WESCO believes the following critical accounting policies affect its judgments and estimates used in the preparation of its consolidated financial statements. WESCO maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. If the financial condition of WESCO's customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. WESCO writes down its inventory for estimated obsolescence or unmarketable inventory equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future demand and market conditions. If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be required. WESCO records its deferred tax assets at amounts that are expected to be realized. WESCO has considered future taxable income and ongoing prudent and feasible tax planning strategies in assessing the potential need for a valuation allowance. Should 19

WESCO determine that it would not be able to realize all or part of its net deferred tax asset in the future, an adjustment to the deferred tax asset would be charged to income in the period such determination was made. WESCO maintains an accounts receivable securitization program (the "Receivables Facility"), whereby we sell, on a continuous basis, to WESCO Receivables Corporation, a wholly-owned, special purpose company ("SPC"), an undivided interest in all domestic accounts receivable. The SPC sells without recourse to a third-party conduit, all the eligible receivables while maintaining a subordinated interest, in the form of overcollateralization, in a portion of the receivables. WESCO accounts for the securitization of accounts receivable in accordance with Statement of Financial Accounting Standards No. 140, "Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities." At the time the receivables are sold, the balances are removed from the balance sheet. The Receivables Facility represents "off-balance sheet financing," since the conduit's ownership interest in the accounts receivable of the SPC results in the removal of accounts receivable from WESCO's consolidated balance sheets, rather than resulting in the addition of a liability to the conduit. We believe that the terms of the agreements governing this facility qualify our trade receivable sales transactions for "sale treatment" under generally accepted accounting principles, which requires WESCO to remove the accounts receivable from our consolidated balance sheets. Absent this "sale treatment," our consolidated balance sheet would reflect additional accounts receivable and debt. Our consolidated statements of operations would not be impacted, except that "Other Expenses" would be classified as "Interest Expense." 2001 DEVELOPMENTS Developments affecting the 2001 results of operations and financial position of WESCO include the following: Economic Trends The electrical distribution industry experienced a significant overall sales decline in the markets where WESCO participates. The 2001 decrease varies dramatically depending upon the product category as well as the market channel used to distribute such product. Based upon our internal estimates, certain of our more significant competitors and suppliers, as a group, experienced an average sales decline of approximately 12% in 2001. WESCO's net sales from core operations decreased approximately 8.6% in 2001 due to: - - Sales to the telecom and semiconductor industries, which were strong in 2000, were considerably weaker in 2001. - - Sales declines were experienced in our large industrial customer base, with many customers closing manufacturing and processing plants and significantly reducing their 2001 MRO and capital spend. - - A significant decline occurred in sales of control and automation products used in plant expansions and plant upgrades. The trend of declining sales has continued into 2002. Core sales for the two months ended February 28, 2002 decreased approximately 12% from the comparable period in 2001, and are in line with Company projections and, adjusted for seasonality, are in line with fourth quarter 2001 run rates. Refinancing The Company has taken the following steps to improve its liquidity: In March 2002, WESCO entered into a $290 million revolving credit agreement with a group of seven financial institutions that is secured by substantially all inventory owned by WESCO and also by the accounts receivable of WESCO Distribution Canada, Inc. Availability under the agreement is based on the amount of eligible inventory and Canadian receivables applied against certain advance rates. Proceeds from this agreement were used to retire the Company's existing revolving credit facility. In August 2001, WESCO completed an offering of $100 million in aggregate principal amount of senior subordinated notes due 2008 with interest payable semi-annually on June 1 and December 1 of each year. The notes were issued with an issue price of 90.142%. The net proceeds received by the Company from the offering were approximately $87.6 million after deducting the initial purchasers' discount and before offering expenses. The net 20

proceeds were used to repay a portion of the outstanding indebtedness of the Company under its then existing revolving credit facility. In September and October of 2001, WESCO entered into several fixed-to-floating interest rate swap agreements with an aggregate notional amount of $100 million. These swaps effectively convert $100 million of the senior subordinated notes from fixed to floating rate debt. In 2001 these agreements had the effect of reducing the interest rate on $100 million of the senior notes from 9.13% to 6.29%. Acquisition In March 2001, WESCO completed its acquisition of all of the outstanding common stock of Herning Underground Supply, Inc. and Alliance Utility Products, Inc. (collectively "Herning") headquartered in Hayward, California. Herning, a distributor serving contractors who install gas, lighting and communication utility infrastructure, reported net sales of approximately $112 million in 2000. This acquisition was accounted for 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 Consolidated Statements of Operations for the periods presented: YEAR ENDED DECEMBER 31 ------------------------------------- 2001 2000 1999 ------------------------------------- Net sales.................................................................. 100.0% 100.0% 100.0% Gross profit............................................................... 17.6 17.6 18.0 Selling, general and administrative expenses............................... 14.1 13.5 13.7 Depreciation and amortization.............................................. 0.9 0.7 0.6 Restructuring charge....................................................... -- 0.2 -- ------------------------------------- Income from operations................................................ 2.6 3.2 3.7 Interest expense........................................................... 1.2 1.1 1.4 Other expenses............................................................. 0.5 0.6 0.6 ------------------------------------- Income before income taxes and extraordinary item..................... 0.9 1.5 1.7 Provision for income taxes................................................. 0.3 0.6 0.7 Extraordinary item, net of tax benefits.................................... -- -- (0.3) ------------------------------------- Net income ........................................................... 0.6% 0.9% 0.7% ===================================== 2001 Compared to 2000 Net Sales. Net sales for the year ended December 31, 2001, decreased by $223.1 million, or 5.7%, to $3.7 billion compared with $3.9 billion in the prior year. The decrease was due principally to sales declines attributable to core business operations of 8.6%, partially offset by sales from acquired companies. Gross Profit. Gross profit for the year ended December 31, 2001, decreased by $40.6 million to $643.5 million from $684.1 million in the prior year due principally to the decline in net sales. Gross profit margin was 17.6% in both 2001 and 2000. Gross profit included other charges of $4.4 million in 2000 related to inventory write-downs. Excluding these charges, gross profit was 17.7% of sales in 2000. The decline in the gross profit percentage is due principally to a decline in supplier rebates, partially offset by increased billing margins. Selling, General and Administrative Expenses ("SG&A"). SG&A expenses decreased by $7.2 million, or 1.4%, to $517.2 million. The year 2000 includes $7.0 million of other charges, related primarily to a deteriorating credit environment and customer bankruptcies that have continued at similar levels in 2001. Core business SG&A expenses decreased $15.7 million or 3.1% from 2000, due principally to decreased payroll costs as the Company reduced its headcount throughout the year as it rebalanced its branch and headquarters staff to be in line with developing economic activity. Additionally, incentive compensation expense decreased in 2001 as sales and profitability declines reduced both commission and bonus requirements. As a percentage of sales, excluding the other charges, SG&A expenses increased to 14.1% in 2001 from 13.3% in 2000, reflecting the negative leverage of lower sales volume. Depreciation and Amortization. Depreciation and amortization increased $6.0 million to $31.0 million in 2001, reflecting depreciation related to increases in property, buildings and equipment over the prior year, higher amortization of goodwill from acquisitions and higher amortization of software costs. In fiscal 2002, WESCO will adopt Statement of Financial Accounting Standards No. 142, "Goodwill and Other Intangible Assets" which is expected to result in a reduction in amortization expense in fiscal 2002 and future years. See Note 2 of the Notes to Consolidated Financial Statements. Income from Operations. Income from operations decreased $30.1 million to $95.3 million in 2001, compared with $125.4 million in 2000. Income from operations in 2000 includes a restructuring charge of $9.4 million. Excluding the restructuring charge and the aforementioned other charges of $11.4 million, operating income decreased by $50.8 million, due principally to the decline in gross profit and the increase in depreciation and amortization. 22

Interest and Other Expenses. Interest expense totaled $45.1 million for 2001, an increase of $1.4 million from 2000. The increase in interest expense results primarily from an increase in average debt level compared to the previous year somewhat offset by lower average interest rates. Other expense totaled $16.9 million and $24.9 million in 2001 and 2000, respectively, reflecting costs associated with the accounts receivable securitization program. The $8.0 million decrease was principally due to a decrease in the program's advance rates. Income Taxes. Income tax expense totaled $13.1 million in 2001, a decrease of $10.1 million from 2000. The effective tax rates for 2001 and 2000 were 39.4% and 41.0%, respectively. The decrease in the rate in 2001 is principally related to the effect of foreign tax credits on decreased pretax income as compared to the prior year. Net Income. Net income and diluted earnings per share totaled $20.2 million and $0.43 per share, respectively, in 2001, compared with $33.4 million and $0.70 per share, respectively, in 2000. 2000 Compared to 1999 Net Sales. Net sales for the year ended December 31, 2000, increased by $457.2 million, or 13.4%, to $3.9 billion compared with $3.4 billion in the prior year. The increase was due principally to sales gains attributable to core business operations of almost 10%, while the remainder of the increase was primarily due to sales of acquired businesses. The mix of direct shipment sales increased to approximately 47% in 2000 from 46% in 1999 principally due to sales gains achieved at Bruckner. The majority of Bruckner's sales are direct shipment. Gross Profit. Gross profit for the year ended December 31, 2000, increased by $67.5 million to $684.1 million from $616.6 million in the prior year. Gross profit margin was 17.6% and 18.0% in 2000 and 1999, respectively. Excluding the effect of the other charges related to inventory rationalization of $4.4 million, gross profit margin decreased to 17.7% from 18.0% in the prior year due, in part, to a shift to lower margin direct ship project sales and also due to increased transportation costs. Selling, General and Administrative Expenses ("SG&A"). SG&A expenses increased $53.0 million, or 11.3%, to $524.3 million. Excluding the impact of the other charges of $7.0 million, related primarily to credit deterioration and bankruptcies, SG&A expenses increased $46.0 million or 9.8%. This increase was primarily due to increased expenses in core business operations and, to a lesser extent, increased SG&A of companies acquired during 1999 and 2000. Core business SG&A expense increased 6% over 1999, due principally to increased payroll costs. As a percentage of sales, excluding the other charges, SG&A expenses declined to 13.3% in 2000 from 13.8% in 1999, reflecting enhanced operating leverage at this higher relative sales volume. Depreciation and Amortization. Depreciation and amortization increased $4.6 million to $25.0 million in 2000, reflecting higher amortization of goodwill from acquisitions and depreciation related to increases in property, buildings and equipment over the prior year. Income from Operations. Income from operations increased $0.4 million to $125.4 million in 2000, compared with $125.0 million in 1999. Excluding the restructuring and other charges in 2000, operating income increased $21.2 million. This increase was primarily due to higher gross profit, partially offset by increased operating costs as explained above. Interest and Other Expenses. Interest expense totaled $43.8 million for 2000, a decrease of $3.2 million from 1999. The decrease was primarily due to the lower level of borrowings since WESCO completed its initial public offering in the second quarter of 1999, as well as the increased amount of securitized accounts receivable. Other expense totaled $24.9 million and $19.5 million in 2000 and 1999, respectively, reflecting costs associated with the accounts receivable securitization program. The $5.4 million increase was principally due to the increased level of securitized accounts receivable noted above. Income Taxes. Income tax expense totaled $23.3 million in 2000, relatively unchanged from 1999. The effective tax rates for 2000 and 1999 were 41.0% and 39.9%, respectively. The increase in the rate in 2000 is principally related to the effect of increased nondeductible expenses on decreased pretax income as compared to the prior year. 23

Income Before Extraordinary Item. Income before extraordinary item totaled $33.4 million, or $0.70 per diluted share, compared with $35.1 million or $0.75 per diluted share, in 1999. Excluding the restructuring charge of $9.4 million, income before extraordinary item was $39.4 million or $0.83 per diluted share. Net Income. Net income and diluted earnings per share totaled $33.4 million and $0.70 per share, respectively, in 2000, compared with $24.6 million and $0.53 per diluted share, respectively, in 1999. Net income in 1999 included an extraordinary item which decreased net income by $10.5 million. LIQUIDITY AND CAPITAL RESOURCES Total assets were approximately $1.2 billion at December 31, 2001, a $3.5 million decrease from December 31, 2000. Stockholders' equity totaled $144.7 million at December 31, 2001, compared with $125.0 million at December 31, 2000. The following table sets forth WESCO's outstanding indebtedness: DECEMBER 31 ----------------------- 2001 2000 ----------------------- (IN MILLIONS) Revolving credit facility............................................................... $ 68.6 $189.6 Senior subordinated notes............................................................... 377.7 291.5 Other................................................................................... 5.6 2.2 ----------------------- 451.9 483.3 Less current portion.................................................................... (5.5) (0.6) ----------------------- $446.4 $482.7 ======================= The following table sets forth details of WESCO's accounts receivable securitization program: DECEMBER 31 ----------------------- 2001 2000 ----------------------- (IN MILLIONS) Securitized accounts receivable......................................................... $398.6 $479.0 Subordinated retained interest ......................................................... (65.6) (100.7) ----------------------- Net accounts receivable removed from balance sheet................................. $333.0 $378.3 ======================= WESCO's liquidity needs arise from seasonal working capital requirements, capital expenditures, acquisitions and debt service obligations. In addition, certain of our acquisition agreements contain earn-out provisions based principally on future earnings targets. The most significant of which relates to the acquisition of Bruckner Supply Company, which provides for an earn-out potential of $90 million during any one of the next three years if certain earnings targets are achieved. The maximum amount payable in any single year under this agreement is $30 million. Certain other acquisitions also contain contingent consideration provisions, only one of which could require a significant payment. Management estimates this payment could range from $0 to $20 million and would be made in 2008. To meet its funding requirements, WESCO uses a mix of internally generated cash flow, its revolving credit facility, its Receivables Facility and equity transactions. 24

The following table summarizes the impact of these items from 1999 to 2001: DECEMBER 31 -------------------------------------- 2001 2000 1999 -------------------------------------- (IN MILLIONS) LIQUIDITY NEEDS Working capital and other assets and liabilities.............................. $140.4 $(64.1) $(68.5) Capital expenditures, net of asset sales......................................

(16.6) 141.1 166.4 -------------------------------------- Net change in cash............................................................ $ 54.0 $ 12.3 $ 0.7 ====================================== In 2002, WESCO anticipates capital expenditures to be similar to 2001, but expects acquisitions of businesses to be significantly lower. As of February 28, 2002, the Company has no specific near term plans to make an acquisition. Acquisition related earn-out payments, if required, will be based on the performance of recently acquired companies. Management anticipates that working capital requirements could increase by $50 million or more in 2002 after the significant reduction achieved in 2001. The required annual principal repayments for the next five years, as of December 31, 2001 and after giving effect to the new revolving credit facility described below, are as follows: AS OF AFTER GIVING EFFECT TO DECEMBER 31, NEW REVOLVING CREDIT 2001 FACILITY --------------------------------------------------- (IN THOUSANDS) --------------------------------------------------- 2002..................................................... $ 5,530 $5,530 2003..................................................... 30 30 2004..................................................... 68,614 30 2005..................................................... 30 30 2006..................................................... 6 6 New Revolving Credit Facility In March 2002, WESCO Distribution entered into a $290 million revolving credit agreement that is secured by substantially all inventory owned by WESCO and also by the accounts receivable of WESCO Canada. Availability under the agreement, which matures in 2007, is based on the amount of eligible inventory and Canadian receivables applied against certain advance rates. Proceeds from this agreement were used to retire WESCO's existing revolving credit facility. Future proceeds from this facility can be used for general corporate purposes including acquisitions, share repurchases, and bond redemptions. Interest on this facility will be determined by LIBOR plus a margin that will range between 200 basis points to 275 basis points depending upon the amount of excess availability under the facility. As long as the average daily excess availability for both the preceding and projected succeeding 90 day period is greater than $50 million, then WESCO would be permitted to make acquisitions and repurchase outstanding public stock and bonds. The above permitted transactions would also be allowed if such excess availability is between $25 million and $50 million and WESCO's fixed charge coverage ratio, as defined by the agreement, is at least 1.25 to 1.0 after taking into consideration the permitted transaction. Additionally, if WESCO's excess availability under the agreement is less than $50 million, then WESCO must maintain a fixed charge coverage ratio of 1.1 to 1.0. At the date of inception, WESCO was in compliance with all covenants of the new credit facility. 25

Former Revolving Credit Facility In June 1999, WESCO Distribution entered into a revolving credit facility with a syndicate of financial institutions. At December 31, 2001, the revolving credit facility, which matures in June 2004, consisted of up to $228 million of revolving loans denominated in U.S. dollars and a Canadian sublimit totaling US$35 million. Borrowings under the revolving credit facility are collateralized by substantially all of the assets of WESCO Distribution other than real property and the accounts receivable sold under the receivables facility, and are guaranteed by WESCO International and certain subsidiaries. The LIBOR borrowing margins applicable to advances under the revolving credit facility range from 150 to 250 basis points, depending upon our leverage ratio. This facility also had various restrictive covenants including financial ratios. WESCO was in compliance with all such covenants as of December 31, 2001. Debt Offering In August 2001, WESCO completed an offering of $100 million in aggregate principal amount of senior subordinated notes due 2008. The notes were issued with an issue price of 90.142%. The net proceeds received by the Company from the offering were approximately $87.6 million after deducting the initial purchasers' discount and before offering expenses. The net proceeds were used to repay a portion of the outstanding indebtedness of the Company under its then existing revolving credit facility. Interest Rate Swap Agreements During September and October of 2001, WESCO entered into four separate fixed-to-floating interest rate swap agreements, each with a notional amount of $25 million. These agreements have six-year terms expiring concurrently with the 9.13% senior subordinated notes with the intent of converting $100 million of the senior subordinated notes from a fixed to floating rate facility. Pursuant to these agreements, WESCO will receive fixed interest payments at the rate of 9.13% and will pay interest at three month LIBOR plus a premium. The LIBOR rates in the agreements are reset quarterly. In 2001, the agreements had the effect of reducing the interest rate on $100 million of the senior notes from 9.13% to 6.29%. WESCO entered into interest rate swap agreements as a means to hedge its interest rate exposure and maintain certain amounts of variable rate and fixed rate debt. Since the swaps have been designated as hedging instruments, their fair values are reflected in the Company's Consolidated Balance Sheets. Net amounts to be received or paid under the swap agreements are reflected as adjustments to interest expense. Accounts Receivable Securitization Program WESCO maintains a Receivables Facility with a group of financial institutions with a purchase commitment up to $396 million. Under the Receivables Facility, WESCO sells, on a continuous basis, to WESCO Receivables Corporation, a wholly-owned SPC, an undivided interest in all domestic accounts receivable. The SPC sells without recourse to a third-party conduit, all the eligible receivables while maintaining a subordinated interest, in the form of overcollateralization, in a portion of the receivables. WESCO has agreed to continue servicing the sold receivables for the financial institution at market rates; accordingly, no servicing asset or liability has been recorded. See Note 5 of the Notes to Consolidated Financial Statements. Initial Public Offering On May 17, 1999, WESCO completed its initial public offering (the "Offering") of 11,183,750 shares of common stock at $18.00 per share. In connection with the Offering, certain employee rights to require WESCO to repurchase outstanding redeemable common stock were terminated and approximately $31.5 million of convertible notes were converted into 1,747,228 shares of common stock. Proceeds from the Offering (after deducting Offering costs) totaling $186.8 million and borrowings of approximately $65 million were used to redeem all of the 11 1/8% senior discount notes ($62.8 million) and to repay the revolving credit and term loan facilities ($188.8 million). Share Repurchase Program In May 2000, WESCO International's board of directors authorized an additional $25 million to be added to its existing $25 million share repurchase program which was authorized in November 1999. As of December 31, 2001, WESCO International had purchased approximately 3.9 million shares for approximately $32.8 million pursuant to this program. On August 3, 2001, WESCO Distribution entered into an amendment to its former revolving credit 26

facility, which, among other things, prohibited WESCO International from purchasing its shares of common stock. Subsequently, as mentioned above, WESCO entered into a new revolving credit facility that allows WESCO International to purchase shares of its common stock assuming certain financial ratios are met. An analysis of cash flows for 2001 and 2000 follows: Operating Activities. Cash provided by operating activities totaled $161.1 million for the year ended December 31, 2001, compared to $46.9 million a year ago. Cash provided by operations in 2001 includes $45.0 million used by our accounts receivable securitization program. Cash provided by operations in 2000 includes $40.0 million from the sale of accounts receivable in connection with the accounts receivable securitization program. Excluding these transactions, operating activities provided $206.1 million in 2001 and $6.9 million in 2000. On this basis, the year-to-year increase in operating cash flow of $199.2 million was primarily due to an improvement in working capital. Investing Activities. Net cash used in investing activities was $69.2 million in 2001, compared to $60.7 million in 2000. Cash used for investing activities was higher in 2001 primarily due to amounts invested in business acquisitions, partially offset by reduced capital expenditures in 2001. Capital expenditures in 2001 were $13.8 million compared to $21.6 million in 2000 and were for computer equipment and software, and branch and distribution center facility improvements. Financing Activities. Cash used by financing activities was $38.0 million in 2001 which was primarily due to net debt repayments of $37.2 million. Cash provided by financing activities was $26.0 million in 2000 which was primarily due to net borrowings of $53.3 million, partially offset by the Company's share purchase program. The following summarizes WESCO's contractual obligations at December 31, 2001, and the effect such obligations are expected to have on its liquidity and cash flow in future periods. Contractual Cash Obligations and Other Commercial Commitments (IN MILLIONS) --------------------------------------------------------- 2003 to 2005 to AFTER TOTAL 2002 2004 2006 2006 --------------------------------------------------------- Contractual Cash Obligations: Revolving credit facility........................... $ 68.6 $ -- $ 68.6 $ -- $ -- Senior subordinated notes........................... 400.0 -- -- -- 400.0 Non-cancelable operating leases..................... 92.6 25.5 34.5 17.0 15.6 Other long-term obligations......................... 15.6 15.5 0.1 -- -- --------------------------------------------------------- Total Contractual Cash Obligations.................. $ 576.8 $41.0 $103.2 $17.0 $415.6 ========================================================= (IN MILLIONS) --------------------------------------------------------- 2003 to 2005 to AFTER TOTAL 2002 2004 2006 2006 --------------------------------------------------------- Other Commercial Commitments: Letters of Credit .................................. $1.0 $ 1.0 $ -- $ -- $ -- Management believes that cash generated from operations, together with amounts available under the credit agreement and the receivables facility, will be sufficient to meet WESCO's working capital, capital expenditures and other cash requirements for the foreseeable future. There can be no assurance, however, that this will be the case. Financing of acquisitions can be funded under the existing credit agreement and may, depending on the number and size of the acquisitions, require the issuance of additional debt and equity securities. 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 not had a material impact on the Company's results of operations. 27

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 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 a 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. IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS In June 1998, the Financial Accounting Standards Board ("FASB") issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities." This statement, as amended by SFAS No. 138, was adopted by WESCO on January 1, 2001. This statement requires the recognition of the fair value of any derivative financial instrument on the balance sheet. Changes in fair value of the derivative and, in certain instances, changes in the fair value of an underlying hedged asset or liability, are recognized through either income or as a component of other comprehensive income. The adoption of this statement did not have a material impact on the results of operations or financial position of WESCO. In July 2001, the FASB issued SFAS No. 141, "Business Combinations" and SFAS No. 142, "Goodwill and Other Intangible Assets." Under SFAS No. 141, all business combinations are accounted for under the purchase method. Under SFAS No. 142, goodwill will no longer be amortized, but will be reduced only if it is found to be impaired. Goodwill would be tested for impairment annually or more frequently when events or circumstances occur indicating that goodwill might be impaired. A fair-value based impairment test would be used to measure goodwill for impairment. As goodwill is measured as a residual amount in an acquisition, it is not possible to directly measure the fair value of goodwill. Under this statement, the net assets of a reporting unit are subtracted from the fair value of that reporting unit to determine the implied fair value of goodwill. An impairment loss would be recognized to the extent the carrying amount of goodwill exceeds the implied fair value. The provisions of this statement are effective for all business combinations completed after July 1, 2001 and fiscal years beginning after December 15, 2001 for existing goodwill. As required by this statement, management is currently evaluating its goodwill for impairment and has not yet completed its analysis. Management believes the adoption of this standard will have a material non-cash impact on WESCO's results of operations due to goodwill no longer being amortized. Goodwill amortization was $11.9 million in 2001. In June 2001, the FASB issued SFAS No. 143, "Accounting for Obligations Associated with the Retirement of Long-Lived Assets". This statement, is required to be adopted by WESCO January 1, 2003, although earlier adoption is permitted. The objectives of SFAS No. 143 are to establish accounting standards for the recognition and measurement of an asset retirement obligation and its associated asset retirement cost. It applies to legal obligations that result from the acquisition, construction, development, or the normal operation of a long-lived asset, excluding certain obligations of leases. Management believes the adoption of this standard will not have a material impact on the results of operations or financial position of WESCO. In August 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment of Long-Lived Assets". This statement addresses financial accounting and reporting for the impairment of long-lived assets and for long-lived assets to be disposed of and supersedes SFAS No. 121. This statement retains the fundamental provisions of SFAS No. 121 for recognition and measurement of the impairment of long-lived assets to be held and used and measurement of long-lived assets to be disposed of by sale, whether previously held and used or newly acquired. This statement was adopted by WESCO as of January 1, 2002. The adoption of this statement did not have a material impact on the results of operations or financial position of WESCO. ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS. FOREIGN CURRENCY RISKS Over 90% of WESCO's sales are denominated in United States dollars and are primarily from customers in the United States. As a result, currency fluctuations are currently not material to WESCO's operating results. WESCO does have foreign subsidiaries located in North America, Europe and Asia and may establish additional foreign 28

subsidiaries in the future. Accordingly, WESCO may derive a more significant portion of its sales from international operations and a portion of these sales may be denominated in foreign currencies. As a result, WESCO's future operating results could become subject to fluctuations in the exchange rates of those currencies in relation to the United States dollar. Furthermore, to the extent that WESCO engages in international sales denominated in United States dollars, an increase in the value of the United States dollar relative to foreign currencies could make WESCO's products less competitive in international markets. WESCO has and will continue to monitor its exposure to currency fluctuations. INTEREST RATE RISKS WESCO's indebtedness as of December 31, 2001 is comprised of $68.6 million of variable-rate borrowings outstanding under its revolving credit facility and $383.4 million of fixed-rate borrowings. Interest cost under the revolving credit facility is based on various indices plus a borrowing margin. In September and October of 2001, WESCO entered into several fixed-to-floating interest rate swap agreements with an aggregate notional amount of $100 million. Under the terms of these agreements, WESCO pays interest on the notional amount of the swap at LIBOR plus a premium and receives fixed payments at the rate of 9 1/8%. The LIBOR rates in the agreements are reset quarterly. At December 31, 2001 the net fair value of interest-rate-related derivatives designated as fair value hedges of debt was $3.2 million. These interest rate swap agreements reduced interest expense by approximately $0.6 million in 2001. At December 31, 2001, we had approximately $169 million of variable rate debt. A hypothetical 10% change in interest rates based on these variable-rate borrowing levels would result in a $0.6 million increase or decrease in interest expense. ITEM 8.

REPORT OF INDEPENDENT ACCOUNTANTS To the Stockholders and Board of Directors of WESCO International, Inc.: In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, stockholders' equity and redeemable common stock and cash flows present fairly, in all material respects, the financial position of WESCO International, Inc. and its subsidiaries (collectively, "WESCO") at December 31, 2001 and 2000, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2001, in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of WESCO's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with auditing standards generally accepted in the United States of America, which require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In addition, WESCO repaid approximately $379.1 million of then outstanding indebtedness, and sold 29,604,351 shares of common stock to an investor group led by affiliates of the Cypress Group LLC ("Cypress") representing approximately 88.7% of WESCO at that time for an aggregate cash consideration of $318.1 million. Existing management retained approximately an 11.3% interest in WESCO immediately following the transaction. WESCO funded the equity consideration and the repayment of indebtedness from proceeds of the cash equity contribution, issuance of approximately $351 million of senior subordinated and senior discount notes, a $170 million credit facility and the sale of approximately $250 million of accounts receivable. Given the 11.3% retained ownership, the transaction was treated as a recapitalization for financial reporting purposes and, accordingly, the historical bases of WESCO's assets and liabilities were not affected. 2. ACCOUNTING POLICIES Basis of Presentation The consolidated financial statements include the accounts of WESCO International, Inc. and all of its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying disclosures. Although these estimates are based on management's best knowledge of current events and actions the Company may undertake in the future, actual results may ultimately differ from the estimates. Revenue Recognition Revenues are recognized when title, ownership and risk of loss pass to the customer, or services are rendered. Shipping and Handling Costs and Fees WESCO records all costs and fees associated with transporting its products to customers as a component of selling, general and administrative expenses. Cash Equivalents Cash equivalents are defined as highly liquid investments with original maturities of 90 days or less when purchased. Asset Securitization WESCO accounts for the securitization of accounts receivable in accordance with Statement of Financial Accounting Standards ("SFAS") No. 140, "Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities." At the time the receivables are sold the balances are removed from the balance sheet. 41

SFAS No. 140 also requires retained interests in the transferred assets to be measured by allocating the previous carrying amount between the assets sold and retained interests based on their relative fair values at the date of transfer. The Company estimates fair value based on the present value of expected future cash flows discounted at a rate commensurate with the risks involved. 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. The Company makes provisions for obsolete or slow-moving inventories as necessary to properly reflect inventory value. Reserves for excess and obsolete inventories were $16.8 million and $18.7 million at December 31, 2001 and 2000, respectively. Property, Buildings and Equipment Property, buildings and equipment are recorded at cost. Depreciation expense is determined using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized over either their respective lease terms or their estimated lives, whichever is shorter. Estimated useful lives range from five to forty years for buildings and leasehold improvements, three to seven years for furniture, fixtures and equipment and two to five years for software costs. 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. Intangible Assets Goodwill arising from acquisitions and other intangible assets are amortized on a straight-line basis over periods ranging from 25 to 35 years. The carrying values of individual components of intangible assets are regularly reviewed by evaluating the estimated future undiscounted cash flows to determine recoverability of the assets. Any decrease in value is recognized on a current basis. As discussed in Recent Accounting Pronouncements in this note, WESCO will adopt SFAS No. 141 and SFAS No. 142 effective January 1, 2002. Income Taxes Income taxes are accounted for under the liability method. Deferred tax assets and liabilities are determined based on differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Valuation allowances, if any, are 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 all of WESCO'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 the end of each period. Income statement accounts are translated at the average exchange rate prevailing during the period. 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. Treasury Stock Common stock purchased for treasury is recorded at cost. At the date of subsequent reissue, the treasury stock account is reduced by the cost of such stock on the weighted average cost basis. Fair Value of Financial Instruments For certain of WESCO's financial instruments, including cash and cash equivalents, short-term investments, accounts receivable, notes payable and short-term borrowings, accounts payable and other accrued liabilities, the carrying amounts approximate fair value due to their short maturities. The estimated fair value of WESCO's senior subordinated notes was $374.0 million at December 31, 2001, compared to a carrying value of $377.8 million. The estimated 42

fair value of the debt is based primarily on quoted market prices, as well as borrowing rates currently available to WESCO for bank loans with similar terms and maturities. Interest Rate Swaps WESCO enters into interest rate swap agreements to reduce the exposure of its debt to interest rate risk and formally documents this strategy as part of its risk management program. Interest rate swaps are used to modify the market risk exposures for a portion of WESCO's debt to achieve LIBOR-based floating interest expense. The swap transactions generally involve the exchange of fixed for floating interest payment obligations and are accounted for as fair value hedges. The gain or loss on the derivative instrument, as well as the offsetting gain or loss on the hedged item, is recognized in earnings in the current period. WESCO estimates the fair value of derivatives based on quoted market prices or pricing models using current market rates, and records all derivatives on the balance sheet at fair value. At December 31, 2001, the net fair value of interest-rate-related derivatives designated as fair value hedges of debt was $3.2 million and is recorded in non-current liabilities. Cash flows from derivative instruments are presented in a manner consistent with the underlying transaction. Environmental Expenditures WESCO 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. Reclassifications Certain prior period amounts have been reclassified to conform with the current year presentation. Recent Accounting Pronouncements In June 1998, the Financial Accounting Standards Board ("FASB") issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities." This statement, as amended by SFAS No. 138, was adopted by WESCO on January 1, 2001. This statement requires the recognition of the fair value of any derivative financial instrument on the balance sheet. Changes in fair value of the derivative and, in certain instances, changes in the fair value of an underlying hedged asset or liability, are recognized through either income or as a component of other comprehensive income. The adoption of this statement did not have a material impact on the results of operations or financial position of WESCO. In July 2001, the FASB issued SFAS No. 141, "Business Combinations" and SFAS No. 142, "Goodwill and Other Intangible Assets." Under SFAS No. 141, all business combinations are accounted for under the purchase method. Under SFAS No. 142, goodwill will no longer be amortized, but will be reduced only if it is found to be impaired. Goodwill would be tested for impairment annually or more frequently when events or circumstances occur indicating that goodwill might be impaired. A fair-value based impairment test would be used to measure goodwill for impairment. As goodwill is measured as a residual amount in an acquisition, it is not possible to directly measure the fair value of goodwill. Under this statement, the net assets of a reporting unit are subtracted from the fair value of that reporting unit to determine the implied fair value of goodwill. An impairment loss would be recognized to the extent the carrying amount of goodwill exceeds the implied fair value. The provisions of this statement are effective for all business combinations completed after July 1, 2001 and fiscal years beginning after December 15, 2001 for existing goodwill. As required by this statement, management is currently evaluating its goodwill for impairment and has not yet completed its analysis. Management believes the adoption of this standard will have a material non-cash impact on WESCO's results of operations due to goodwill no longer being amortized. Goodwill amortization was $11.9 million in 2001. In June 2001, the FASB issued SFAS No. 143, "Accounting for Obligations Associated with the Retirement of Long-Lived Assets". This statement, is required to be adopted by WESCO January 1, 2003, although earlier adoption is permitted. The objectives of SFAS No. 143 are to establish accounting standards for the recognition and 43

measurement of an asset retirement obligation and its associated asset retirement cost. It applies to legal obligations that result from the acquisition, construction, development, or the normal operation of a long-lived asset, excluding certain obligations of leases. Management believes the adoption of this standard will not have a material impact on the results of operations or financial position of WESCO. In August 2001, the FASB issued SFAS No. 144, "Accounting for the Impairment of Long-Lived Assets". This statement addresses financial accounting and reporting for the impairment of long-lived assets and for long-lived assets to be disposed of and supersedes SFAS No. 121. This statement retains the fundamental provisions of SFAS No. 121 for recognition and measurement of the impairment of long-lived assets to be held and used and measurement of long-lived assets to be disposed of by sale, whether previously held and used or newly acquired. This statement was adopted by WESCO as of January 1, 2002. The adoption of this statement did not have a material impact on the results of operations or financial position of WESCO. 3. INITIAL PUBLIC OFFERING On May 17, 1999, WESCO completed its initial public offering of 11,183,750 shares of common stock ("Offering") at $18.00 per share. In connection with the Offering, certain employee rights to require WESCO to repurchase outstanding redeemable common stock were terminated and approximately $31.5 million of convertible notes were converted into 1,747,228 shares of common stock. Proceeds from the Offering (after deducting Offering costs of $14.5 million) totaling $186.8 million and borrowings of approximately $65 million were used to redeem all of the 11 1/8% senior discount notes ($62.8 million) and to repay the existing revolving credit and term loan facilities ($188.8 million). In connection with the Offering, the Board of Directors approved a 57.8 to one stock split effected in the form of a stock dividend of WESCO's common stock. The Board of Directors also reclassified the Class A common stock into common stock, increased the authorized common stock to 210,000,000 shares and the authorized Class B common stock to 20,000,000 shares and authorized 20,000,000 shares of $.01 par value preferred stock, all effective May 11, 1999. In this report, all share and per share data have been restated to reflect the stock split. 4. RESTRUCTURING CHARGE In the fourth quarter of 2000, WESCO commenced certain programs to reduce costs, improve productivity and exit certain operations. Total costs under these programs were $9.4 million, and were comprised of $5.4 million related to the closure of fourteen branch operations in the United States, Canada and the Balkans, and $4.0 million related to the write-down of an investment in an affiliate. The $5.4 million charge related to the closure of fourteen branch operations is principally comprised of an inventory write-down of approximately $4.0 million and lease termination costs of approximately $1.0 million, the majority of which was paid in 2001. The $4.0 million investment write-down was a result of management's decision to no longer pursue its business strategy with an affiliate. 5. ACCOUNTS RECEIVABLE SECURITIZATION In June 1999, WESCO and certain of its subsidiaries terminated its previous accounts receivable securitization program and entered into a new accounts receivable securitization program ("Receivables Facility"). Under the Receivables Facility, WESCO sells, on a continuous basis, to WESCO Receivables Corporation, a wholly-owned, special purpose company ("SPC"), an undivided interest in all domestic accounts receivable. The SPC sells without recourse to a third-party conduit all the eligible receivables while maintaining a subordinated interest, in the form of overcollateralization, in a portion of the receivables. WESCO has agreed to continue servicing the sold receivables for the financial institution at market rates; accordingly, no servicing asset or liability has been recorded. As of December 31, 2001 and 2000, securitized accounts receivable totaled approximately $398 million and $479 million, respectively, of which the subordinated retained interest was approximately $65 million and $101 million, respectively. Accordingly, approximately $333 million and $378 million of accounts receivable balances were removed from the consolidated balance sheets at December 31, 2001 and 2000, respectively. WESCO reduced its 44

accounts receivable securitization program by $45.0 million in 2001. Net proceeds from the transactions totaled $40.0 million in 2000. Costs associated with the Receivables Facility totaled $16.9 million, $24.9 million and $19.5 million in 2001, 2000 and 1999, respectively. These amounts are recorded as other expenses in the consolidated statement of operations and are primarily related to the discount and loss on the sale of accounts receivables, partially offset by related servicing revenue. The key economic assumptions used to measure the retained interest at the date of the securitization for securitizations completed in 2001 were a discount rate of 3% and an estimated life of 1.5 months. At December 31, 2001, an immediate adverse change in the discount rate or estimated life of 10% and 20% would result in a reduction in the fair value of the retained interest of $0.1 million and $0.3 million, respectively. These sensitivities are hypothetical and should be used with caution. As the figures indicate, changes in fair value based on a 10% variation in assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, in this example, the effect of a variation in a particular assumption on the fair value of the retained interest is calculated without changing any other assumption. In reality, changes in one factor may result in changes in another. 6. ACQUISITIONS In March 2001, WESCO acquired a distributor serving contractors who install gas, lighting and communication utility infrastructure. In 2000 and 1999, WESCO acquired three and four electrical distributors, respectively. Certain of the acquisitions also contain contingent consideration provisions that are not material to the consolidated financial statements of WESCO. A summary of certain information with respect to all acquisitions follows: YEAR ENDED DECEMBER 31 ------------------------------------------ 2001 2000 1999 ------------------------------------------ (IN THOUSANDS) Aggregate purchase price, including contingent consideration............. $62,956 $47,801 $40,076 Recorded goodwill........................................................ 47,339 38,223 25,455 All of the acquisitions were 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 prospectively from the acquisition dates. 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 consolidated results reported herein. On September 11, 1998, WESCO acquired substantially all the assets and assumed substantially all liabilities and obligations relating to the operations of Bruckner Supply Company, Inc. ("Bruckner"), a privately owned company headquartered in Port Washington, New York. Bruckner is a provider of integrated supply procurement and outsourcing activities for large industrial companies. Additional contingent consideration, if any, is to be paid based on a multiple of increases in earnings before interest, taxes, depreciation and amortization of Bruckner through 2004. Up to 50% of the additional future contingent consideration, if any, may be converted at the election of the holder into common stock at the then market value. The purchase agreement provides for an additional earn-out potential of $90 million during any one of the next three years if certain earning targets are achieved. The maximum amount payable in any single year under this agreement is $30 million. Certain other acquisitions also contain contingent consideration provisions, one of which could require a significant payment in 2008. 7. CONCENTRATIONS OF CREDIT RISK AND SIGNIFICANT SUPPLIERS WESCO distributes its products and services and extends credit to a large number of customers in the industrial, construction, utility and manufactured structures markets. In addition, one supplier accounted for approximately 14%, 13% and 13% of WESCO's purchases for each of the three years, 2001, 2000 and 1999, respectively. 45

Revolving Credit Facility In June 1999, WESCO Distribution, Inc., a wholly-owned subsidiary of WESCO, entered into a $400 million revolving credit facility with certain financial institutions. The revolving credit facility, which matures in June 2004, consists of up to $365 million of revolving loans denominated in U.S. dollars and a Canadian sublimit totaling US$35 million. Borrowings under the revolving credit facility are collateralized by substantially all the assets of WESCO Distribution, Inc. other than real property and accounts receivable sold under the Receivables Facility, and are guaranteed by WESCO International, Inc. and certain subsidiaries. In August 2001, WESCO Distribution, Inc. entered into an amendment to its revolving credit facility, which, among other things, affected the pricing of and amounts available under the revolving credit facility. The LIBOR borrowing margins applicable to advances under the revolving credit facility, which previously ranged from 100 to 200 basis points, were amended to range from 150 to 250 basis points depending upon WESCO's leverage ratio. The amendment also provided for reduction in the maximum amount available under the revolving credit facility from approximately $379 million to approximately $263 million. The amendment further provided for subsequent quarterly decreases in the maximum amount available as follows: - beginning January 1, 2002 through July 1, 2002, the maximum amount available will be reduced by $5 million per quarter; - from October 1, 2002 through January 1, 2004, the maximum amount available will be reduced by $12.5 million per quarter; and 46

- on April 1, 2004, the maximum amount available will be reduced by $10 million. Borrowings bear rates of interest equal to various indices, at WESCO's option, such as LIBOR, Prime Rate or the Federal Funds Rate, plus a borrowing margin based on WESCO's financial performance. At December 31, 2001 and December 31, 2000, the interest rates on revolving credit facility borrowings were 6.0% and 8.4%, respectively. A commitment fee of 30 to 50 basis points per year is due on unused portions of the revolving credit facility. As discussed in Note 20, in March 2002 WESCO Distribution, Inc. terminated the revolving credit facility discussed above and entered into a $290 million revolving credit agreement that is collateralized by substantially all inventory owned by WESCO and also by the accounts receivable of WESCO Distribution Canada, Inc. Senior Subordinated Notes In August 2001, WESCO completed an offering of $100 million in aggregate principal amount of 9 1/8% senior subordinated notes due on June 1, 2008. The notes were issued with an issue price of 90.142%. The net proceeds received by WESCO from the offering were approximately $87.6 million after deducting the initial purchasers' discount and before offering expenses. The net proceeds were used to repay a portion of the outstanding indebtedness of the Company under its revolving credit facility. The senior subordinated notes in an aggregate principal amount of $400 million were issued by WESCO Distribution, Inc. The notes are unsecured obligations and are fully and unconditionally guaranteed by WESCO International, Inc. The senior subordinated notes bear interest at a stated rate of 9 1/8% payable semiannually on June 1 and December 1 through June 1, 2008. The effective interest rate for the senior subordinated notes is 9.6%. The senior subordinated notes are redeemable at the option of WESCO Distribution, Inc. in whole or in part, at any time after June 1, 2003 at the following prices: Redemption Price ---------------- 2003............................................... 104.563% 2004............................................... 103.042 2005............................................... 101.521 2006 and thereafter................................ 100.000 At any time prior to June 1, 2003, the senior subordinated notes may be redeemed, in whole but not in part, at the option of the Company at any time within 180 days after a change of control, at a redemption price equal to the principal amount thereof plus accrued and unpaid interest and the then applicable premium. In addition, the noteholders have the right to require WESCO, upon a change of control, to repurchase all or any part of the senior subordinated notes at a redemption price equal to 101% of the principal amount provided plus accrued and unpaid interest. In September and October 2001, WESCO entered into certain interest rate swap agreements with respect to $100 million notional amount of indebtedness. Pursuant to the agreements, WESCO will receive semi-annual fixed interest payments at the rate of 9 1/8% commencing December 1, 2001 and will make quarterly variable interest rate payments at rates based on LIBOR plus a margin commencing December 1, 2001 (currently rates range from 6.051% to 6.241%). The swap agreements terminate on June 1, 2008. Other At December 31, 2001 and 2000, other borrowings primarily consisted of notes issued to sellers in connection with acquisitions. 47

The following table sets forth the aggregate principal repayment requirements for all indebtedness for the next five years without giving effect to the new revolving credit agreement: (IN THOUSANDS) ---------------------- 2002......................................... $ 5,530 2003......................................... 30 2004 ........................................ 68,614 2005......................................... 30 2006......................................... 6 WESCO's credit agreements contain various restrictive covenants that, among other things, impose limitations on (i) dividend payments or certain other restricted payments or investments; (ii) the incurrence of additional indebtedness and guarantees or issuance of additional stock; (iii) creation of liens; (iv) mergers, consolidation or sales of substantially all of WESCO's assets; (v) certain transactions among affiliates; (vi) payments by certain subsidiaries to WESCO; and (vii) capital expenditures. In addition, the agreements require WESCO to meet certain leverage, working capital and interest coverage ratios. WESCO was in compliance with all such covenants at December 31, 2001. WESCO is permitted to pay dividends under certain limited circumstances. At December 31, 2001 and 2000, no retained earnings were available for dividend payments. WESCO had $1.0 million and $0.5 million of outstanding letters of credit at December 31, 2001 and 2000, respectively. These letters of credit are used as collateral for potential obligation under WESCO's insurance programs as well as certain foreign commercial transactions. The fair value of the letters of credit approximates the contract value. 10. CAPITAL STOCK Preferred Stock There are 20,000,000 shares of preferred stock authorized at a par value of $.01 per share. The Board of Directors has the authority, without further action by the stockholders, to issue all authorized preferred shares in one or more series and to fix the number of shares, designations, voting powers, preferences, optional and other special rights and the restrictions or qualifications thereof. The rights, preferences, privileges and powers of each series of preferred stock may differ with respect to dividend rates, liquidation values, voting rights, conversion rights, redemption provisions and other matters. Common Stock There are 210,000,000 shares of common stock and 20,000,000 shares of Class B common stock authorized at a par value of $.01 per share. The Class B common stock is identical to the 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 common stock. Redeemable Common Stock Prior to the Offering, certain employees and key management of WESCO held common stock and options that required WESCO to repurchase, under certain conditions, death, disability or termination without cause during the term of employment, all of the shares and the exercisable portion of the options held. In connection with these redemption features, WESCO had classified outside of permanent equity, an amount representing the initial fair value of the redeemable shares. These shares and exercisable options were not marked to market since the events of redemption were considered remote. This repurchase right terminated upon the consummation of the Offering and as a result, the redeemable shares were reclassified to stockholders' equity. 48

WESCO's common stock may be purchased at management's discretion, subject to certain financial ratios, in open market transactions and the program may be discontinued at any time. As of December 31, 2001, the Company had purchased 3,898,000 shares of its common stock for $32.8 million pursuant to this program. 11.

EARNINGS PER SHARE Basic earnings per share is computed by dividing net income by the weighted average common shares outstanding during the periods. Diluted earnings per share are computed by dividing net income by the weighted average common shares and common share equivalents outstanding during the periods. The dilutive effect of common share equivalents is considered in the diluted earnings per share computation using the treasury stock method. The following table sets forth the details of basic and diluted earnings per share: YEAR ENDED DECEMBER 31 --------------------------------------------------- 2001 2000 1999 --------------------------------------------------- (DOLLARS IN THOUSANDS, EXCEPT SHARE DATA) Income before extraordinary item...................... $20,225 $33,438 $35,145 Interest on convertible debt........................... -- -- 595 --------------------------------------------------- Earnings used in diluted earnings per share............ $20,225 $33,438 $35,740 Weighted average common shares outstanding used in computing basic earnings per share.................. 44,862,087 45,326,475 43,057,894 Common shares issuable upon exercise of dilutive stock options ............................................ 2,039,586 2,420,132 3,516,733 Assumed conversion of convertible debt................. -- -- 949,912 --------------------------------------------------- Weighted average common shares outstanding and common share equivalents used in computing diluted earnings per share.................................. 46,901,673 47,746,607 47,524,539 =================================================== Earnings per share before extraordinary item Basic............................................... $0.45 $0.74 $0.82 Diluted............................................. $0.43 0.70 0.75 50

Options to purchase 4.4 million and 3.8 million shares of common stock at a weighted average exercise price of $10.24 per share and $10.62 per share were outstanding as of December 31, 2001 and 2000, respectively, but were not included in the computation of diluted earnings per share because the option exercise prices were greater than the average market price of WESCO common stock. 13. EMPLOYEE BENEFIT PLANS A majority of WESCO's employees are covered by defined contribution retirement savings plans for their service rendered subsequent to WESCO's formation. U.S. employee contributions of not more than 6% of eligible compensation are matched 50% by WESCO. WESCO's contributions for Canadian employees range from 1% to 6% of eligible compensation based on years of service. For the years ended December 31, 2001, 2000 and 1999, WESCO contributed $5.5 million, $5.5 million and $6.0 million, respectively, which was charged to expense. Contributions may be taken in the form of WESCO's stock at the employee's election. In addition, employer profit sharing contributions may be made at the discretion of the Board of Directors and can be based on WESCO's financial performance. No such contributions were made during 2001, 2000 or 1999. 14. STOCK INCENTIVE PLANS Stock Purchase Plans In connection with the Recapitalization, WESCO established a stock purchase plan ("1998 Stock Purchase Plan") under which certain employees may be granted an opportunity to purchase WESCO's common stock. The maximum number of shares available for purchase may not exceed 427,720. There were no shares issued in 2001, 2000 or 1999. In 1994, WESCO established a stock purchase plan ("1994 Stock Purchase Plan") under which certain employees were granted an opportunity to purchase WESCO's common stock. Future purchases of shares under the 1994 Stock Purchase Plan were terminated in conjunction with the establishment of the 1998 Stock Purchase Plan. Stock Option Plans WESCO has sponsored four stock option plans, the 1999 Long-Term Incentive Plan ("LTIP"), the 1998 Stock Option Plan, the Stock Option Plan for Branch Employees and the 1994 Stock Option Plan. The LTIP was designed to be the successor plan to all prior plans. Outstanding options under prior plans will continue to be governed by their existing terms, which are substantially similar to the LTIP. Any remaining shares reserved for future issuance under the prior plans are available for issuance under the LTIP. The LTIP is administered by the Compensation Committee of the Board of Directors. An initial reserve of 6,936,000 shares of common stock has been authorized for issuance under the LTIP. This reserve automatically increases by (i) the number of shares of common stock covered by unexercised options granted under prior plans that are canceled or terminated after the effective date of the LTIP and (ii) the number of shares of common stock surrendered by employees to pay the exercise price and/or minimum withholding taxes in connection with the exercise of stock options granted under our prior plans. Options granted vest and become exercisable over periods ranging from four to five years or earlier based on WESCO achieving certain financial performance criteria. All options vest immediately 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. All awards under WESCO's stock incentive plans are designed to be issued at fair market value. The following sets forth shares of common stock reserved for future issuance at December 31, 2001: Stock Purchase Plan......................................... 135,830 LTIP........................................................ 6,879,000 51

If compensation costs had been determined based on the fair value at the grant dates according to SFAS No. 123, WESCO's net income and earnings per share would have been as follows: YEAR ENDED DECEMBER 31 ------------------------------------------ 2001 2000 1999 ------------------------------------------ (IN THOUSANDS, EXCEPT SHARE DATA) Net income (loss) As reported......................................................... $20,225 $33,438 $24,638 Pro forma........................................................... 17,351 30,979 22,912 Basic earnings (loss) per share As reported......................................................... $0.45 $0.74 $0.57 Pro forma........................................................... 0.39 0.68 0.53 Diluted earnings (loss) per share As reported......................................................... $0.43 $0.70 $0.53 Pro forma........................................................... 0.37 0.65 0.49 The weighted average fair value per option granted was $2.99, $4.82 and $8.00 for the years ended December 31, 2001, 2000 and 1999, respectively. 52

For purposes of presenting pro forma results, the fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model and the following assumptions: YEAR ENDED DECEMBER 31 ------------------------------------- 2001 2000 1999 ------------------------------------- Risk-free interest rate.................. 4.9% 6.0% 6.0% Expected life (years).................... 6.0 6.0 7.0 Stock price volatility................... 65.0% 45.0% 30.0% 15.

WESCO has litigation arising from time to time in the normal course of business. In management's opinion, any present litigation WESCO is aware of will not materially affect WESCO's consolidated financial position, results of operations or cash flows. 16. SEGMENTS AND RELATED INFORMATION WESCO is engaged principally in one line of business -- the sale of electrical products and maintenance repair and operating supplies -- which represents more than 90% of the consolidated net sales, income from operations and assets, for 2001, 2000 and 1999. There were no material amounts of sales or transfers among geographic areas and no material amounts of export sales.

SUBSEQUENT EVENT In March 2002, WESCO Distribution, Inc. entered into a $290 million revolving credit agreement that is collateralized by substantially all inventory owned by WESCO and also by the accounts receivable of WESCO Distribution Canada, Inc. Availability under the agreement, which matures in 2007, is limited to the amount of eligible inventory and Canadian receivables applied against certain advance rates. Proceeds from this agreement were used to retire WESCO Distribution, Inc.'s existing revolving credit facility. Interest on this facility will be at LIBOR plus a margin that will range between 2.0% to 2.75% depending upon the amount of excess availability under the facility. As long as the average daily excess availability for both the preceding and projected succeeding 90 day period is greater than $50 million, then WESCO would be permitted to make acquisitions and repurchase outstanding public stock and bonds. The above permitted transactions would also be allowed if such excess availability is between $25 million and $50 million but WESCO's fixed charge coverage ratio, as defined by the agreement, is at least 1.25 to 1.0 after taking into consideration the permitted transaction. Additionally, if WESCO's excess availability under the agreement is less than $50 million, then WESCO must maintain a fixed charge coverage ratio of 1.1 to 1.0. At the date of inception, WESCO was in compliance with all covenants of the new facility. 60

All Annexes, Disclosure Schedules, Exhibits and other attachments (collectively, "APPENDICES") hereto, or expressly identified to this Agreement, are incorporated herein by reference, and taken together with this Agreement, shall constitute but a single agreement. These Recitals shall be construed as part of the Agreement. NOW, THEREFORE, in consideration of the premises and the mutual covenants hereinafter contained, and for other good and valuable consideration, the parties hereto agree as follows: 1. AMOUNT AND TERMS OF CREDIT 1.1 CREDIT FACILITIES. (a) REVOLVING CREDIT FACILITY. (i) Subject to the terms and conditions hereof, each Lender agrees to make available to Borrower from time to time until the Commitment Termination Date its Pro Rata Share of advances (each, a "REVOLVING CREDIT ADVANCE"). The Pro Rata Share of the Revolving Loan of any Lender shall not at any time exceed its separate Revolving Loan Commitment. The obligations of each Lender hereunder shall be several and not joint. Until the Commitment Termination Date, Borrower may from time to time borrow, repay and reborrow 2

under this Section 1.1(a); provided, that the amount of any Revolving Credit Advance to be made at any time shall not exceed Borrowing Availability at such time. Borrowing Availability may be further reduced by Reserves imposed by Agent in its reasonable credit judgment. Until the Commitment Termination Date, Borrower may from time to time borrow, repay and reborrow under this SECTION 1.1(a). Each Revolving Credit Advance shall be made on notice by Borrower to one of the representatives of Agent identified in SCHEDULE 1.1 at the address specified therein. Any such notice must be given no later than (1) 12:00 noon (New York time) on the Business Day of the proposed Revolving Credit Advance, in the case of an Index Rate Loan, or (2) 12:00 noon (New York time) on the date which is 3 Business Days prior to the proposed Revolving Credit Advance, in the case of a LIBOR Loan. Each such notice (a "NOTICE OF REVOLVING CREDIT ADVANCE") must be given in writing (by telecopy or overnight courier) substantially in the form of EXHIBIT 1.1(a)(i), and shall include the information required in such Exhibit and such other information as may be required by Agent. If Borrower desires to have the Revolving Credit Advances bear interest by reference to a LIBOR Rate, it must comply with SECTION 1.5(e). (ii) Except as provided in SECTION 1.12, Borrower shall execute and deliver to each Lender a note to evidence the Revolving Loan Commitment of that Lender. Each note shall be in the principal amount of the Revolving Loan Commitment of the applicable Lender, dated the Closing Date and substantially in the form of EXHIBIT 1.1(a)(ii) (each a "REVOLVING NOTE" and, collectively, the "REVOLVING NOTES"). Each Revolving Note shall represent the obligation of Borrower to pay the amount of Lender's Revolving Loan Commitment or, if less, such Lender's Pro Rata Share of the aggregate unpaid principal amount of all Revolving Credit Advances to Borrower together with interest thereon as prescribed in SECTION 1.5. The entire unpaid balance of the Revolving Loan and all other non-contingent Obligations shall be immediately due and payable in full in immediately available funds on the Commitment Termination Date. (iii) Any provision of this Agreement to the contrary notwithstanding, at the request of Borrower, in its discretion Agent may (but shall have absolutely no obligation to), make Revolving Credit Advances to Borrower on behalf of Lenders in amounts that cause the outstanding balance of the aggregate Revolving Loan to exceed the Borrowing Base (less the Swing Line Loan) (any such excess Revolving Credit Advances are herein referred to collectively as "OVERADVANCES"); provided that (A) no such event or occurrence shall cause or constitute a waiver of Agent's, the Swing Line Lender's or Lenders' right to refuse to make any further Overadvances, Swing Line Advances or Revolving Credit Advances, or incur any Letter of Credit Obligations, as the case may be, at any time that an Overadvance exists, and (B) no Overadvance shall result in a Default or Event of Default due to Borrower's failure to comply with SECTION 1.3(b)(i) for so long as Agent permits such Overadvance to remain outstanding, but solely with respect to the amount of such Overadvance. In addition, Overadvances may be made even if the conditions to lending set forth in SECTION 2 have not been met. All Overadvances shall constitute Index Rate Loans, shall bear interest at the Default Rate and shall be payable on demand. Except as otherwise provided in SECTION 1.11(b), the authority of Agent to make Overadvances is limited to an aggregate amount not to exceed $15,000,000 at any time, shall not cause the Revolving Loan to exceed the Maximum Amount, shall not result in Overadvances being outstanding for more than 90 days in any 180-day period, and may be revoked 3

prospectively by a written notice to Agent signed by Lenders holding more than 50% of the Revolving Loan Commitments. (b) SWING LINE FACILITY. (i) Agent shall notify the Swing Line Lender upon Agent's receipt of any Notice of Revolving Credit Advance. Subject to the terms and conditions hereof, the Swing Line Lender may, in its discretion, make available from time to time until the Commitment Termination Date advances (each, a "SWING LINE ADVANCE") in accordance with any such notice. The provisions of this SECTION 1.1(b) shall not relieve Lenders of their obligations to make Revolving Credit Advances under SECTION 1.1(a); provided that if the Swing Line Lender makes a Swing Line Advance pursuant to any such notice, such Swing Line Advance shall be in lieu of any Revolving Credit Advance that otherwise may be made by Lenders pursuant to such notice. The aggregate amount of Swing Line Advances outstanding shall not exceed at any time the lesser of (A) the Swing Line Commitment and (B) the lesser of the Maximum Amount and (except for Overadvances) the Borrowing Base, in each case, less the outstanding balance of the Revolving Loan at such time ("SWING LINE AVAILABILITY"). Until the Commitment Termination Date, Borrower may from time to time borrow, repay and reborrow under this SECTION 1.1(b). Each Swing Line Advance shall be made pursuant to a Notice of Revolving Credit advance delivered by Borrower to Agent in accordance with SECTION 1.1(a). Any such notice must be given no later than 1:00 p.m. (New York time) on the Business Day of the proposed Swing Line Advance. Unless the Swing Line Lender has received at least one Business Day's prior written notice from Requisite Lenders instructing it not to make a Swing Line Advance, the Swing Line Lender shall, notwithstanding the failure of any condition precedent set forth in SECTION 2.2, be entitled to fund that Swing Line Advance, and to have such Lender make Revolving Credit Advances in accordance with SECTION 1.1(b)(iii) or purchase participating interests in accordance with SECTION 1.1(b)(iv). Notwithstanding any other provision of this Agreement or the other Loan Documents, the Swing Line Loan shall constitute a Loan bearing interest at the commercial paper rate plus the Applicable Revolver LIBOR Margin as provided in SECTION 1.5(a) and no Swing Line Loan shall remain outstanding for more than five (5) Business Days. Borrower shall repay the aggregate outstanding principal amount of the Swing Line Loan upon demand therefor by Agent. (ii) Borrower shall execute and deliver to the Swing Line Lender a promissory note to evidence the Swing Line Commitment. Such note shall be in the principal amount of the Swing Line Commitment of the Swing Line Lender, dated the Closing Date and substantially in the form of EXHIBIT 1.1(b)(ii) (the "SWING LINE NOTE"). The Swing Line Note shall represent the obligation of Borrower to pay the amount of the Swing Line Commitment or, if less, the aggregate unpaid principal amount of all Swing Line Advances made to Borrower together with interest thereon as prescribed in SECTION 1.5. The entire unpaid balance of the Swing Line Loan and all other noncontingent Obligations shall be immediately due and payable in full in immediately available funds on the Commitment Termination Date if not sooner paid in full. (iii) The Swing Line Lender, at any time and from time to time in its sole and absolute discretion, may on behalf of Borrower (and Borrower hereby irrevocably 4

authorizes the Swing Line Lender to so act on its behalf) request each Lender (including the Swing Line Lender) to make a Revolving Credit Advance to Borrower (which shall be an Index Rate Loan) in an amount equal to that Lender's Pro Rata Share of the principal amount of the Swing Line Loan (the "REFUNDED SWING LINE LOAN") outstanding on the date such notice is given. Unless any of the events described in SECTIONS 8.1(h) OR 8.1(i) has occurred (in which event the procedures of SECTION 1.1(b)(iv) shall apply) and regardless of whether the conditions precedent set forth in this Agreement to the making of a Revolving Credit Advance are then satisfied, each Lender shall disburse directly to Agent, its Pro Rata Share of a Revolving Credit Advance on behalf of the Swing Line Lender, prior to 3:00 p.m. (New York time), in immediately available funds on the Business Day next succeeding the date that notice is given. The proceeds of those Revolving Credit Advances shall be immediately paid to the Swing Line Lender and applied to repay the Refunded Swing Line Loan. (iv) If, prior to refunding a Swing Line Loan with a Revolving Credit Advance pursuant to SECTION 1.1(b)(iii), one of the events described in SECTIONS 8.1(h) OR 8.1(I) has occurred, then, subject to the provisions of SECTION 1.1(b)(v) below, each Lender shall, on the date such Revolving Credit Advance was to have been made for the benefit of Borrower, purchase from the Swing Line Lender an undivided participation interest in the Swing Line Loan in an amount equal to its Pro Rata Share of such Swing Line Loan. Upon request, each Lender shall promptly transfer to the Swing Line Lender, in immediately available funds, the amount of its participation interest. (v) Each Lender's obligation to make Revolving Credit Advances in accordance with SECTION 1.1(b)(iii) and to purchase participation interests in accordance with SECTION 1.1(b)(iv) shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right that such Lender may have against the Swing Line Lender, Borrower or any other Person for any reason whatsoever; (B) the occurrence or continuance of any Default or Event of Default; (C) any inability of Borrower to satisfy the conditions precedent to borrowing set forth in this Agreement at any time or (D) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing. If any Lender does not make available to Agent or the Swing Line Lender, as applicable, the amount required pursuant to SECTIONS 1.1(b)(iii) OR 1.1(b)(iv), as the case may be, the Swing Line Lender shall be entitled to recover such amount on demand from such Lender, together with interest thereon for each day from the date of non-payment until such amount is paid in full at the Federal Funds Rate for the first two Business Days and at the Index Rate thereafter. (c) RELIANCE ON NOTICES. Agent shall be entitled to rely upon, and shall be fully protected in relying upon, any Notice of Revolving Credit Advance, Notice of Conversion/Continuation or similar notice believed by Agent to be genuine. Agent may assume that each Person executing and delivering any notice in accordance herewith was duly authorized, unless the responsible individual acting thereon for Agent has actual knowledge to the contrary. 1.2 LETTERS OF CREDIT. Subject to and in accordance with the terms and conditions contained herein and in Annex B, Borrower shall have the right to request, and 5

Lenders agree to incur, or purchase participations in, Letter of Credit Obligations in respect of Borrower. 1.3 PREPAYMENTS. (a) VOLUNTARY PREPAYMENTS; REDUCTIONS IN REVOLVING LOAN COMMITMENTS. Borrower may at any time on at least 5 days' prior written notice to Agent permanently reduce (but not terminate) the Revolving Loan Commitment; PROVIDED that (A) any such reductions shall be in a minimum amount of $5,000,000 and integral multiples of $1,000,000 in excess of such amount, (B) the Revolving Loan Commitment shall not be reduced to an amount less than the amount of the Revolving Loan then outstanding, plus $25,000,000, and (C) after giving effect to such reduction, Borrower shall comply with SECTION 1.3(b)(i). Borrower may at any time on at least ten 10 days' prior written notice to Agent terminate the Revolving Loan Commitment, PROVIDED that upon such termination all Loans and other Obligations shall be immediately due and payable in full and all Letter of Credit Obligations shall be cash collateralized or otherwise satisfied in accordance with ANNEX B hereto. Any reduction or termination of the Revolving Loan Commitment must be accompanied by the payment of any LIBOR funding breakage costs in accordance with SECTION 1.13(b). Upon any such reduction or termination of the Revolving Loan Commitment, Borrower's right to request Revolving Credit Advances, or request that Letter of Credit Obligations be incurred on its behalf, or request Swing Line Advances, shall simultaneously be permanently reduced or terminated, as the case may be; PROVIDED that a permanent reduction of the Revolving Loan Commitment shall not require a corresponding pro rata reduction in the L/C Sublimit. (b) MANDATORY PREPAYMENTS. (i) If at any time the outstanding balances of the Revolving Loan and the Swing Line Loan exceed the lesser of (A) the Maximum Amount and (B) the Borrowing Base, Borrower shall immediately repay the aggregate outstanding Revolving Credit Advances to the extent required to eliminate such excess. If any such excess remains after repayment in full of the aggregate outstanding Revolving Credit Advances, Borrower shall provide cash collateral for the Letter of Credit Obligations in the manner set forth in ANNEX B to the extent required to eliminate such excess. Notwithstanding the foregoing, any Overadvance made pursuant to SECTION 1.1(a)(iii) shall be repaid only on demand. (ii) Immediately upon receipt by any Credit Party of proceeds of any asset disposition (excluding proceeds of asset dispositions permitted by SECTION 6.8(a)) or any sale of Stock of any Subsidiary of any Credit Party or of any incurrence of Indebtedness in a mortgage financing transaction permitted under SECTION 6.3(a)(x) or the incurrence of any other Indebtedness from any third party in a transaction permitted under SECTION 6.3 (other than the issuance of additional Subordinated Notes, which shall be governed by CLAUSE (IV) below), Borrower shall prepay the Loans in an amount equal to all such proceeds, net of (A) commissions and other reasonable and customary transaction costs, fees and expenses properly attributable to such transaction and payable by Borrower in connection therewith (in each case, paid to non-Affiliates), (B) transfer taxes, (C) amounts payable to holders of senior Liens (to the extent such Liens constitute Permitted Encumbrances hereunder), if any (D) an appropriate reserve for 6

Any such prepayment shall be applied in accordance with SECTION 1.3(c). (iv) If Borrower issues additional Subordinated Notes in a transaction permitted under SECTION 6.3(a)(xvi) and the other provisions of this Agreement, no later than the first Business Day following the date of receipt of the net proceeds thereof, Borrower shall prepay the Loans in an amount equal to all such proceeds (and correspondingly permanently reduce the amount of the Revolving Loan Commitment). Any such prepayment shall be applied in accordance with SECTION 1.3(c). (c) APPLICATION OF CERTAIN MANDATORY PREPAYMENTS. Any prepayments made by Borrower pursuant to SECTIONS 1.3(b)(ii) OR (b)(iii) above shall be applied as follows: FIRST, to Fees and reimbursable expenses of Agent then due and payable pursuant to any of the Loan Documents; SECOND, to interest then due and payable on the Swing Line Loan; THIRD, to the principal balance of the Swing Line Loan until the same has been repaid in full; FOURTH, to interest then due and payable on the Revolving Credit Advances; FIFTH, to the outstanding principal balance of Revolving Credit Advances until the same has been paid in full; and SIXTH, to any Letter of Credit Obligations, to provide cash collateral therefor in the manner set forth in ANNEX B, until all such Letter of Credit Obligations have been fully cash collateralized in the manner set forth in ANNEX B. Neither the Revolving Loan Commitment nor the Swing Line Commitment shall be permanently reduced by the amount of any such prepayments; PROVIDED, HOWEVER, notwithstanding the foregoing, the Revolving Loan Commitment shall be permanently reduced by the amount of any such prepayments made pursuant to SECTION 1.3(b)(iv). (d) APPLICATION OF PREPAYMENTS FROM INSURANCE PROCEEDS AND CONDEMNATION PROCEEDS. Prepayments from insurance or condemnation proceeds in accordance with SECTION 5.4(c) and insurance or condemnation proceeds from casualties or losses to Equipment, Fixtures and Real Estate, respectively, shall be applied as follows: insurance proceeds from casualties or losses shall be applied first, to the Swing Line Loans and, second, to the Revolving Credit Advances. Neither the Revolving Loan Commitment nor the Swing Line Loan Commitment shall be permanently reduced by the amount of any such prepayments. 7

(e) NO IMPLIED CONSENT. Nothing in this SECTION 1.3 shall be construed to constitute Agent's or any Lender's consent to any transaction that is not permitted by other provisions of this Agreement or the other Loan Documents. 1.4 USE OF PROCEEDS. Borrower shall utilize the proceeds of the Revolving Loan and the Swing Line Loan solely for the Refinancing (and to pay any related transaction expenses), and for the financing of Borrower's ordinary working capital and general corporate needs, including to the extent, and only to the extent, (i) set forth in SECTION 6.3 to be used by Borrower to make intercompany loans and advances to Credit Parties which are Guarantors and other Subsidiaries of Borrower but solely to the extent permitted hereunder, (ii) set forth in SECTION 6.14, to be used by Borrower in connection with the repurchase of either Holdings' publicly traded common Stock or the Subordinated Notes in a transaction consummated in a transaction expressly permitted under SECTION 6.14 and (iii) set forth in SECTION 6.1, to be used by Borrower in connection with the consummation of a Permitted Acquisition consummated in compliance with each of the terms and conditions of SECTION 6.1. DISCLOSURE SCHEDULE (1.4) contains a description of Borrower's sources and uses of funds as of the Closing Date, including Loans and Letter of Credit Obligations to be made or incurred on that date, and a funds flow memorandum detailing how funds from each source are to be transferred to particular uses. 1.5 INTEREST AND APPLICABLE MARGINS. (a) Borrower shall pay interest to Agent, for the ratable benefit of Lenders in accordance with the various Loans being made by each Lender, in arrears on each applicable Interest Payment Date, at the following rates: (i) with respect to the Revolving Credit Advances, the Index Rate plus the Applicable Revolver Index Margin per annum or, at the election of Borrower, the applicable LIBOR Rate plus the Applicable Revolver LIBOR Margin per annum, based on the aggregate Revolving Credit Advances outstanding from time to time; (ii) with respect to the Swing Line Loan, at the rate equal to the last month end published rate for 30 day dealer commercial paper (high grade unsecured notes sold through dealers by major corporations in multiples of $1,000) which normally appears in the "Money Rate" column of the Wall Street Journal, plus the Applicable Revolver LIBOR Margin per annum. As of the Closing Date, the Applicable Margins are as follows: Applicable Revolver Index Margin 1.00% Applicable Revolver LIBOR Margin 2.50% Applicable L/C Margin 2.50% Applicable Unused Line Fee Margin .50% 8

The Applicable Margins shall be adjusted (up or down) prospectively as determined by Borrower's average daily excess Borrowing Availability for the quarter then ended, commencing with the first day of the first calendar month that occurs more than five (5) days after delivery of Borrower's Compliance Certificate to Lenders for the Fiscal Quarter ending June 30, 2002. Adjustments in Applicable Margins will be determined by reference to the following grids: (x) For Interest and Letter of Credit Fees: - ------------------------------------------------------------------------------------------------------------ IF EXCESS BORROWING LEVEL OF AVAILABILITY IS: APPLICABLE MARGINS: - --------------- ------------------- - ----------------------------------------------------------------------------------------------------------- Less than 50,000,000 Level I - ----------------------------------------------------------------------------------------------------------- Less than 125,000,000, but equal to or greater than 50,000,000 Level II - ----------------------------------------------------------------------------------------------------------- equal to or less than 150,000,000, but equal to or greater than 125,000,000 Level III - ----------------------------------------------------------------------------------------------------------- greater than 150,000,000 Level IV - ----------------------------------------------------------------------------------------------------------- - -------------------------------------------------------------------------------------------------------- APPLICABLE MARGINS ------------------ - -------------------------------------------------------------------------------------------------------- LEVEL I LEVEL II LEVEL III LEVEL IV ------- -------- --------- -------- Applicable Revolver 1.25% 1.00% 0.75% 0.50% - -------------------------------------- --------------- --------------- ---------------- --------------- Index Margin - -------------------------------------- --------------- --------------- ---------------- --------------- Applicable Revolver LIBOR 2.75% 2.50% 2.25% 2.00% - -------------------------------------- --------------- --------------- ---------------- --------------- Margin - -------------------------------------- --------------- --------------- ---------------- --------------- Applicable L/C Margin 2.75% 2.50% 2.25% 2.00% - -------------------------------------- --------------- --------------- ---------------- --------------- (y) For Unused Line Fee: - -------------------------------------------------------------------------------- IF THE PERCENTAGE OF THE AVERAGE FOR THE PERIOD OF THE DAILY CLOSING BALANCES OF THE REVOLVING LOAN OUTSTANDING TO LEVEL OF THE MAXIMUM AMOUNT IS: APPLICABLE MARGIN: - ---------------------- ------------------ - -------------------------------------------------------------------------------- equal to or less than 33% Level A - ---------------------------------------- -------------------------------------- greater than 33% Level B - ---------------------------------------- -------------------------------------- - ----------------------------------------------------------------------- APPLICABLE MARGINS ------------------ - ----------------------------------------------------------------------- LEVEL A Level B - -------------------------------------- --------------- --------------- Applicable Unused Line Fee .50% .375% Margin - -------------------------------------- --------------- --------------- All adjustments in the Applicable Margins after August 1, 2002, shall be implemented quarterly on a prospective basis, for each calendar month commencing at least 5 days after the date of delivery to Lenders of the quarterly unaudited or annual audited (as applicable) Financial Statements evidencing the need for an adjustment. Concurrently with the 9

delivery of the Compliance Certificate, Borrower shall deliver to Agent and Lenders a certificate, signed by its chief financial officer, setting forth in reasonable detail the basis for the continuance of, or any change in, the Applicable Margins. Failure to deliver the Compliance Certificate within 5 days of the required date of delivery shall, in addition to any other remedy provided for in this Agreement, result in an increase in the Applicable Margins to the highest level set forth in the foregoing grid, until the first day of the first calendar month following the delivery of a Compliance Certificate demonstrating that such an increase is not required. If a Default or an Event of Default has occurred and is continuing at the time any reduction in the Applicable Margins is to be implemented, that reduction shall be deferred until the first day of the first calendar month following the date on which such Default or Event of Default is waived or cured. (b) If any payment on any Loan becomes due and payable on a day other than a Business Day, the maturity thereof will be extended to the next succeeding Business Day (except as set forth in the definition of LIBOR Period) and, with respect to payments of principal, interest thereon shall be payable at the then applicable rate during such extension. (c) All computations of Fees calculated on a per annum basis and interest shall be made by Agent on the basis of a 360-day year, in each case for the actual number of days occurring in the period for which such interest and Fees are payable. The Index Rate is a floating rate determined for each day. Each determination by Agent of an interest rate and Fees hereunder shall be final, binding and conclusive on Borrower, absent manifest error. (d) So long as an Event of Default has occurred and is continuing under SECTION 8.1 (a), (h) OR (i), or so long as any other Default or Event of Default has occurred and is continuing and at the election of Agent (or upon the written request of Requisite Lenders) confirmed by written notice from Agent to Borrower, the interest rates applicable to the Loans and the Letter of Credit Fees shall be increased by two percentage points (2%) per annum above the rates of interest or the rate of such Fees otherwise applicable hereunder ("DEFAULT RATE"), and all outstanding Obligations shall bear interest at the Default Rate applicable to such Obligations. Interest and Letter of Credit Fees at the Default Rate shall accrue from the initial date of such Default or Event of Default until that Default or Event of Default is cured or waived and shall be payable upon demand. (e) Subject to the conditions precedent set forth in SECTION 2.2, Borrower shall have the option to (i) request that any Revolving Credit Advance be made as a LIBOR Loan, (ii) convert at any time all or any part of outstanding Loans (other than the Swing Line Loan) from Index Rate Loans to LIBOR Loans, (iii) convert any LIBOR Loan to an Index Rate Loan, subject to payment of LIBOR breakage costs in accordance with SECTION 1.13(b) if such conversion is made prior to the expiration of the LIBOR Period applicable thereto, or (iv) continue all or any portion of any Loan (other than the Swing Line Loan) as a LIBOR Loan upon the expiration of the applicable LIBOR Period and the succeeding LIBOR Period of that continued Loan shall commence on the first day after the last day of the LIBOR Period of the Loan to be continued. Any Loan or group of Loans having the same proposed LIBOR Period to be made or continued as, or converted into, a LIBOR Loan must be in a minimum amount of $5,000,000 and integral multiples of $1,000,000 in excess of such amount. Any such election must be made by 12:00 noon (New York time) on the 3rd Business Day prior to (1) the date of any proposed Advance 10

which is to bear interest at the LIBOR Rate, (2) the end of each LIBOR Period with respect to any LIBOR Loans to be continued as such, or (3) the date on which Borrower wishes to convert any Index Rate Loan to a LIBOR Loan for a LIBOR Period designated by Borrower in such election. If no election is received with respect to a LIBOR Loan by 12:00 noon (New York time) on the 3rd Business Day prior to the end of the LIBOR Period with respect thereto (or if a Default or an Event of Default has occurred and is continuing or the additional conditions precedent set forth in SECTION 2.2 shall not have been satisfied), that LIBOR Loan shall be converted to an Index Rate Loan at the end of its LIBOR Period. Borrower must make such election by notice to Agent in writing, by telecopy or overnight courier. In the case of any conversion or continuation, such election must be made pursuant to a written notice (a "NOTICE OF CONVERSION/CONTINUATION") in the form of EXHIBIT 1.5(e). (f) Notwithstanding anything to the contrary set forth in this SECTION 1.5, if a court of competent jurisdiction determines in a final order that the rate of interest payable hereunder exceeds the highest rate of interest permissible under law (the "MAXIMUM LAWFUL RATE"), then so long as the Maximum Lawful Rate would be so exceeded, the rate of interest payable hereunder shall be equal to the Maximum Lawful Rate; PROVIDED, HOWEVER, that if at any time thereafter the rate of interest payable hereunder is less than the Maximum Lawful Rate, Borrower shall continue to pay interest hereunder at the Maximum Lawful Rate until such time as the total interest received by Agent, on behalf of Lenders, is equal to the total interest that would have been received had the interest rate payable hereunder been (but for the operation of this paragraph) the interest rate payable since the Closing Date as otherwise provided in this Agreement. Thereafter, interest hereunder shall be paid at the rate(s) of interest and in the manner provided in SECTIONS 1.5(a) THROUGH (e), unless and until the rate of interest again exceeds the Maximum Lawful Rate, and at that time this paragraph shall again apply. In no event shall the total interest received by any Lender pursuant to the terms hereof exceed the amount that such Lender could lawfully have received had the interest due hereunder been calculated for the full term hereof at the Maximum Lawful Rate. If the Maximum Lawful Rate is calculated pursuant to this paragraph, such interest shall be calculated at a daily rate equal to the Maximum Lawful Rate divided by the number of days in the year in which such calculation is made. If, notwithstanding the provisions of this SECTION 1.5(f), a court of competent jurisdiction shall finally determine that a Lender has received interest hereunder in excess of the Maximum Lawful Rate, Agent shall, to the extent permitted by applicable law, promptly apply such excess in the order specified in SECTION 1.11 and thereafter shall refund any excess to Borrower or as a court of competent jurisdiction may otherwise order. (g) INTEREST ACT (CANADA). For purposes of disclosure pursuant to the Interest Act (Canada), the annual rates of interest or fees to which the rates of interest or fees provided in this Agreement and the other Loan Documents (as stated herein or therein, as applicable, to be computed on the basis of a 360 or 365 day year or any other period of time less than a calendar year) are equivalent are the rates so determined multiplied by the actual number of days in the applicable calendar year and divided by 360, 365 or such other period of time, respectively. 11

1.6 ELIGIBLE ACCOUNTS. All of the Accounts owned by WESCO-Canada and reflected in the most recent Borrowing Base Certificate delivered by Borrower to Agent shall be "ELIGIBLE ACCOUNTS" for purposes of this Agreement, except any Account to which any of the exclusionary criteria set forth below applies. Agent shall have the right to establish, modify or eliminate Reserves against Eligible Accounts from time to time in its reasonable credit judgment. In addition, Agent reserves the right, at any time and from time to time after the Closing Date, to adjust any of the criteria set forth below, to establish new criteria and to adjust advance rates with respect to Eligible Accounts, in its reasonable credit judgment, subject to the approval of Supermajority Lenders in the case of adjustments, new criteria, or changes in advance rates or the elimination of Reserves imposed as of the Closing Date which have the effect of making more credit available (it being understood that Agent may in its reasonable credit judgment eliminate Reserves established by it in its reasonable credit judgment after the Closing Date without the necessity of obtaining the approval of Supermajority Lenders or Requisite Lenders). Borrower and the other Credit Parties hereby acknowledge and agree that only Accounts owned by WESCO-Canada, and no Accounts owned by Borrower or any other Credit Party, may constitute Eligible Accounts. Eligible Accounts shall not include any Account of WESCO-Canada: (a) that does not arise from the sale of goods or the performance of services by WESCO-Canada in the ordinary course of its business; (b) (i) upon which WESCO-Canada's right to receive payment is not absolute or is contingent upon the fulfillment of any condition whatsoever or (ii) as to which WESCO-Canada is not able to bring suit or otherwise enforce its remedies against the Account Debtor through judicial process, or (iii) if the Account represents a progress billing consisting of an invoice for goods sold or used or services rendered pursuant to a contract under which the Account Debtor's obligation to pay that invoice is subject to WESCO-Canada's completion of further performance under such contract or is subject to the equitable lien of a surety bond issuer; (c) to the extent that any defense, counterclaim, setoff or dispute is asserted as to such Account; (d) that is not a true and correct statement of bona fide indebtedness incurred in the amount of the Account for merchandise sold to or services rendered and accepted by the applicable Account Debtor; (e) with respect to which an invoice, reasonably acceptable to Agent in form and substance, has not been sent to the applicable Account Debtor; (f) that (i) is not owned by WESCO-Canada or (ii) is subject to any right, claim, security interest or other interest of any other Person, other than Liens in favor of Agent, on behalf of itself and Lenders, and Prior Claims that are unregistered and that secure amounts that are not yet due and payable; 12

(j) to the extent WESCO-Canada, Borrower, any other Credit Party or any Subsidiary thereof is liable for goods sold or services rendered by the applicable Account Debtor to WESCO-Canada, Borrower, any other Credit Party or any Subsidiary thereof but only to the extent of the potential offset; (k) that arises with respect to goods that are delivered on a bill-and-hold, cash-on-delivery basis or placed on consignment, guaranteed sale or other terms by reason of which the payment by the Account Debtor is or may be conditional; (l) that is in default; PROVIDED, THAT, without limiting the generality of the foregoing, an Account shall be deemed in default upon the occurrence of any of the following: (i) the Account is not paid within the earlier of: 60 days following its due date or 90 days following its original invoice date; (ii) the Account Debtor obligated upon such Account suspends business, makes a general assignment for the benefit of creditors or fails to pay its debts generally as they come due; or (iii) a petition is filed by or against any Account Debtor obligated upon such Account under any bankruptcy law or any other United States federal or state or, with 13

All of the inventory owned by the Borrower, WESCO-Canada, WESCO Equity, or Herning and reflected in the most recent Borrowing Base Certificate delivered by Borrower to Agent shall be "Eligible Inventory" for purposes of this Agreement, except any Inventory to which any of the exclusionary criteria set forth below applies. Agent shall have the right to establish, modify, or eliminate Reserves against Eligible Inventory from time to time in its reasonable credit judgment. In addition, Agent reserves the right, at any time and from time to time after the Closing Date, to adjust any of the criteria set forth below, to establish new criteria and to adjust advance rates with respect to Eligible Inventory in its reasonable credit judgment, subject to the approval of Supermajority Lenders in the case of adjustments, new criteria, changes in advance rates or the elimination of Reserves imposed as of the Closing Date which have the effect of making more credit available (it being understood that Agent may in its reasonable credit judgment eliminate Reserves established by it in its reasonable credit judgment 14

after the Closing Date without the necessity of obtaining the approval of Supermajority Lenders or Requisite Lenders). The other Credit Parties hereby acknowledge and agree that only Inventory owned by Borrower, WESCO-Canada, WESCO Equity, or Herning, and no Inventory owned by any other Credit Party, may constitute Eligible Inventory. Eligible Inventory shall not include any Inventory of Borrower, WESCO-Canada, WESCO Equity, or Herning that: (a) is not owned by Borrower, Herning, WESCO Equity, or WESCO-Canada free and clear of all Liens and rights of any other Person (including the rights of a purchaser that has made progress payments and the rights of a surety that has issued a bond to assure Borrower's or WESCO- Canada's performance with respect to that Inventory), except the Liens in favor of Agent, on behalf of itself and Lenders, and in the case of Inventory of WESCO-Canada, Prior Claims that are unregistered and that secure amounts that are not yet due and payable; (b) (i) other than as provided in CLAUSE (VI) below, is not located on premises owned, leased or rented by Borrower, Herning, WESCO Equity or WESCO-Canada and set forth in DISCLOSURE SCHEDULE (3.2) or (ii) is stored at a leased location, unless Agent has given its prior consent thereto and unless (x) a satisfactory landlord waiver has been delivered to Agent or (y) Reserves, if determined in Agent's reasonable credit judgment, satisfactory to Agent have been established with respect thereto, (iii) is stored with a bailee or warehouseman unless a satisfactory, acknowledged bailee letter has been received by Agent or, if determined in Agent's reasonable credit judgment, Reserves satisfactory to Agent have been established with respect thereto, or (iv) is located at an owned location subject to a mortgage (or similar lien under applicable law) in favor of a lender other than Agent, unless a satisfactory mortgagee waiver has been delivered to Agent or Reserves satisfactory to Agent have been established with respect thereto, or (v) is located at any site if the aggregate book value of Inventory at any such location is less than U.S. $100,000 (or the Dollar Equivalent Amount thereof), or (vi) is located on premises owned, leased or rented by a customer of Borrower, Herning or WESCO Equity, unless Agent has given its prior consent thereto, such Inventory of Borrower, Herning or WESCO Equity is clearly segregated from all Inventory of such customer, all UCC filings deemed necessary or desirable by Agent have been made, and a satisfactory collateral access agreement has been delivered to Agent by such customer; (c) is placed on consignment, except as expressly provided in SECTION 1.7(b)(vi) (and subject to compliance with all of the requirements of SECTION 1.7(b)(vi)), is located at any customer location, or is in transit, to the extent the value of such Inventory consists of costs associated with "freight- in" charges, if any, except for Inventory in transit between domestic or Canadian locations of Credit Parties as to which Agent's Liens have been perfected at origin and destination; (d) is covered by a negotiable document of title, unless such document has been delivered to Agent with all necessary endorsements, free and clear of all Liens except those in favor of Agent and Lenders and, in the case of WESCO-Canada, Prior Claims that are unregistered and that secure amounts that are not yet due and payable; (e) is excess, obsolete, unsalable, shopworn, seconds, damaged or unfit for sale; 15

On or prior to the Closing Date, Borrower and WESCO-Canada will each establish and will each maintain until the Termination Date, the cash management systems described in Annex C (the "Cash Management Systems"). 1.9 FEES. (a) Borrower shall pay to GE Capital, individually, the Fees specified in that certain fee letter of even date herewith between Borrower and GE Capital (the "GE CAPITAL FEE LETTER"), at the times specified for payment therein. (b) As additional compensation for the Lenders, Borrower shall pay to Agent, for the ratable benefit of such Lenders, in arrears, on the first Business Day of each month prior to the Commitment Termination Date and on the Commitment Termination Date, a Fee for Borrower's non-use of available funds in an amount equal to the Applicable Unused Line Fee Margin per annum (calculated on the basis of a 360 day year for actual days elapsed) multiplied by the difference between (x) the Maximum Amount (as it may be reduced from time to time) and (y) the average for the period of the daily closing balances of the Revolving Loan outstanding during the period for which the such Fee is due. 16

(c) Borrower shall pay to Agent, for the ratable benefit of Lenders, the Letter of Credit Fee as provided in ANNEX B. 1.10 RECEIPT OF PAYMENTS. Borrower shall make each payment under this Agreement not later than 2:30 p.m. (New York time) on the day when due in immediately available funds in Dollars to the Collection Account. Payments received after 2:30 p.m. New York time on any Business Day or on a day that is not a Business Day shall be deemed to have been received on the following Business Day. If Agent receives any payment from or on behalf of any Credit Party in a currency other than the currency in which an Obligation payable is denominated, Agent may convert the payment (including the monetary proceeds of realization upon any Collateral and any funds then held in a cash collateral account) into Dollars at the exchange rate that Agent would be prepared to sell the currency received in New York, New York on the Business Day immediately preceding the date of actual payment. The Obligations shall be satisfied only to the extent of the amount actually received by Agent upon such conversion. 1.11 APPLICATION AND ALLOCATION OF PAYMENTS. (a) So long as no Default or Event of Default has occurred and is continuing, (i) payments consisting of proceeds of Accounts or Inventory received in the ordinary course of business shall be applied, first, to the Swing Line Loan and, second, to the Revolving Loan; (ii) payments matching specific scheduled payments then due shall be applied to those scheduled payments; (iii) voluntary prepayments shall be applied as determined by Borrower, subject to the provisions of SECTION 1.3(a); and (iv) mandatory prepayments shall be applied as set forth in SECTIONS 1.3(c) AND 1.3(d). All payments and prepayments applied to a particular Loan shall be applied ratably to the portion thereof held by each Lender as determined by its Pro Rata Share. As to any other payment, and as to all payments made when a Default or Event or Default has occurred and is continuing or following the Commitment Termination Date, Borrower hereby irrevocably waives the right to direct the application of any and all payments received from or on behalf of Borrower, and Borrower hereby irrevocably agrees that Agent shall have the continuing exclusive right to apply any and all such payments against the Obligations as Agent may deem advisable notwithstanding any previous entry by Agent in the Loan Account or any other books and records. In the absence of a specific determination by Agent with respect thereto, payments in respect of the Obligations shall be applied to amounts then due and payable in the following order: (1) to Fees and Agent's expenses reimbursable hereunder; (2) to interest on the Swing Line Loan; (3) to principal payments on the Swing Line Loan; (4) to interest on the Revolving Loan; interest accrued as to each Revolving Loan; (5) to principal payments on the Revolving Loan; (6) to provide cash collateral for Letter of Credit Obligations in the manner described in ANNEX B and (7) to all other Obligations including expenses of Lenders to the extent reimbursable under SECTION 11.3; PROVIDED, HOWEVER, that any such payments consisting of proceeds of Canadian property shall be applied to amounts that are due and payable in the following order: (1) to Agent's expenses reimbursable hereunder; (2) to principal payments on the Swing Line Loan; (3) to principal payments on the Revolving Loan; (4) to Fees reimbursable hereunder; (5) to interest on the Swing Line Loan; (6) to interest on the Revolving Loan; interest accrued as to each Revolving Loan; (7) to provide cash collateral for Letter of Credit Obligations in the manner 17

described in ANNEX B and (8) to all other Obligations including expenses of Lenders to the extent reimbursable under SECTION 11.3. (b) Agent is authorized to, and at its sole election may, charge to the Revolving Loan balance on behalf of Borrower and cause to be paid all Fees, expenses, Charges, costs (including insurance premiums in accordance with SECTION 5.4(a)) and interest and principal, other than principal of the Revolving Loan, owing by Borrower under this Agreement or any of the other Loan Documents if and to the extent Borrower fails to pay promptly any such amounts as and when due, even if the amount of such charges would exceed Borrowing Availability at such time. At Agent's option and to the extent permitted by law, any charges so made shall constitute part of the Revolving Loan hereunder. 1.12 LOAN ACCOUNT AND ACCOUNTING. Agent shall maintain a loan account (the "LOAN ACCOUNT") on its books to record: all Advances, all payments made by Borrower, and all other debits and credits as provided in this Agreement with respect to the Loans or any other Obligations. All entries in the Loan Account shall be made in accordance with Agent's customary accounting practices as in effect from time to time. The balance in the Loan Account, as recorded on Agent's most recent printout or other written statement, shall, absent demonstrable error, be presumptive evidence of the amounts due and owing to Agent and Lenders by Borrower; PROVIDED that any failure to so record or any error in so recording shall not limit or otherwise affect Borrower's duty to pay the Obligations. Agent shall render to Borrower a monthly accounting of transactions with respect to the Loans setting forth the balance of the Loan Account for the immediately preceding month. Unless Borrower notifies Agent in writing of any objection to any such accounting (specifically describing the basis for such objection), within 30 days after the date thereof, each and every such accounting shall, absent demonstrable error, be deemed final, binding and conclusive on Borrower in all respects as to all matters reflected therein. Only those items expressly objected to in such notice shall be deemed to be disputed by Borrower. Notwithstanding any provision herein contained to the contrary, any Lender may elect (which election may be revoked) to dispense with the issuance of Notes to that Lender and may rely on the Loan Account as evidence of the amount of Obligations from time to time owing to it. 1.13 INDEMNITY. (a) Each Credit Party that is a signatory hereto shall jointly and severally indemnify and hold harmless each of Agent, Lenders and their respective Affiliates, and each such Person's respective officers, directors, employees, attorneys, agents and representatives (each, an "INDEMNIFIED PERSON"), from and against any and all suits, actions, proceedings, claims, damages, losses, liabilities and expenses (including reasonable attorneys' fees and disbursements and other costs of investigation or defense, including those incurred upon any appeal) that may be instituted or asserted against or incurred by any such Indemnified Person as the result of credit having been extended, suspended or terminated under this Agreement and the other Loan Documents and the administration of such credit, and in connection with or arising out of the transactions contemplated hereunder and thereunder and any actions or failures to act in connection therewith, including any and all Environmental Liabilities and legal costs and 18

expenses arising out of or incurred in connection with disputes between or among ANY PARTIES to any of the Loan Documents (collectively, "INDEMNIFIED LIABILITIES"); PROVIDED, that no such Credit Party shall be liable for any indemnification to an Indemnified Person to the extent that any such suit, action, proceeding, claim, damage, loss, liability or expense results from that Indemnified Person's gross negligence or willful misconduct. NO INDEMNIFIED PERSON SHALL BE RESPONSIBLE OR LIABLE TO ANY OTHER PARTY TO ANY LOAN DOCUMENT, ANY SUCCESSOR, ASSIGNEE OR THIRD PARTY BENEFICIARY OF SUCH PERSON OR ANY OTHER PERSON ASSERTING CLAIMS DERIVATIVELY THROUGH SUCH PARTY, FOR INDIRECT, PUNITIVE, EXEMPLARY OR CONSEQUENTIAL DAMAGES WHICH MAY BE ALLEGED AS A RESULT OF CREDIT HAVING BEEN EXTENDED, SUSPENDED OR TERMINATED UNDER ANY LOAN DOCUMENT OR AS A RESULT OF ANY OTHER TRANSACTION CONTEMPLATED HEREUNDER OR THEREUNDER. (b) To induce Lenders to provide the LIBOR Rate option on the terms provided herein, if (i) any LIBOR Loans are repaid in whole or in part prior to the last day of any applicable LIBOR Period (whether that repayment is made pursuant to any provision of this Agreement or any other Loan Document or occurs as a result of acceleration, by operation of law or otherwise); (ii) Borrower shall default in payment when due of the principal amount of or interest on any LIBOR Loan; (iii) Borrower shall refuse to accept any borrowing of, or shall request a termination of any borrowing, conversion into or continuation of LIBOR Loans after Borrower has given notice requesting the same in accordance herewith; or (iv) Borrower shall fail to make any prepayment of a LIBOR Loan after Borrower has given a notice thereof in accordance herewith, then Borrower shall indemnify and hold harmless each Lender from and against all losses, costs and expenses resulting from or arising from any of the foregoing. Such indemnification shall include any loss (including loss of margin) or expense arising from the reemployment of funds obtained by it or from fees payable to terminate deposits from which such funds were obtained. For the purpose of calculating amounts payable to a Lender under this subsection, each Lender shall be deemed to have actually funded its relevant LIBOR Loan through the purchase of a deposit bearing interest at the LIBOR Rate in an amount equal to the amount of that LIBOR Loan and having a maturity comparable to the relevant LIBOR Period; PROVIDED, that each Lender may fund each of its LIBOR Loans in any manner it sees fit, and the foregoing assumption shall be utilized only for the calculation of amounts payable under this subsection. This covenant shall survive the termination of this Agreement and the payment of the Notes and all other amounts payable hereunder. As promptly as practicable under the circumstances, each Lender shall provide Borrower with its written calculation of all amounts payable pursuant to this SECTION 1.13(b), and such calculation shall be binding on the parties hereto unless Borrower shall object in writing within 10 Business Days of receipt thereof, specifying the basis for such objection in detail. 1.14 ACCESS. Each Credit Party that is a party hereto shall, during normal business hours, from time to time upon three (3) Business Day's prior notice to the Borrower (attention: Treasurer); PROVIDED, HOWEVER, that after the occurrence and during the continuance of a Default or Event of Default, no such prior notice shall be required; as frequently as Agent determines to be 19

appropriate; (a) provide Agent and any of its officers, employees and agents access to its properties, facilities, advisors and employees (including officers) of each Credit Party and to the Collateral, (b) permit Agent, and any of its officers, employees and agents, to inspect, audit and make extracts from any Credit Party's books and records, and (c) permit Agent, and its officers, employees and agents, to inspect, review, evaluate and make test verifications and counts of the Accounts of WESCO-Canada, Inventory of any Credit Party and other Collateral of any Credit Party. Absent a Default or Event of Default, Borrower shall not be required to pay for (i) more than one (1) inventory appraisal per year or (ii) more than two (2) collateral audits per year. If a Default or Event of Default has occurred and is continuing or if access is necessary to preserve or protect the Collateral as determined by the Agent, in its reasonable credit judgment, each such Credit Party shall provide such access to Agent and to each Lender at all times and without advance notice at Borrower's expense. Furthermore, so long as any Event of Default has occurred and is continuing, Borrower shall provide Agent and each Lender with access to its suppliers and customers. Each Credit Party shall make available to Agent and its counsel, as quickly as is possible under the circumstances, originals or copies of all books and records that Agent may reasonably request. Each Credit Party shall deliver any document or instrument necessary for Agent, as it may from time to time request, to obtain records from any service bureau or other Person that maintains records for such Credit Party, and shall maintain duplicate records or supporting documentation on media, including computer tapes and discs owned by such Credit Party. Agent will give Lenders at least 5 days' prior written notice of regularly scheduled audits. Representatives of other Lenders may accompany Agent's representatives on regularly scheduled audits at no charge to Borrower. 1.15 TAXES. (a) Any and all payments by Borrower hereunder or under the Notes shall be made, in accordance with this SECTION 1.15, free and clear of and without deduction for any and all present or future Taxes. If Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under the Notes, (i) the sum payable shall be increased as much as shall be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this SECTION 1.15) Agent or Lenders, as applicable, receive an amount equal to the sum they would have received had no such deductions been made, (ii) Borrower shall make such deductions, and (iii) Borrower shall pay the full amount deducted to the relevant taxing or other authority in accordance with applicable law. Within 30 days after the date of any payment of Taxes, Borrower shall furnish to Agent the original or a certified copy of a receipt evidencing payment thereof. Agent and Lenders shall not be obligated to return or refund any amounts received pursuant to this Section. (b) Each Credit Party that is a signatory hereto shall indemnify and, within 10 days of demand therefor, pay Agent and each Lender for the full amount of Taxes (including any Taxes imposed by any jurisdiction on amounts payable under this SECTION 1.15) paid by Agent or such Lender, as appropriate, and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally asserted. (c) Each Lender organized under the laws of a jurisdiction outside the United States (a "FOREIGN LENDER") as to which payments to be made under this Agreement or under the 20

Notes are exempt from United States withholding tax under an applicable statute or tax treaty shall provide to Borrower and Agent a properly completed and executed IRS Form W-8ECI or Form W-8BEN or other applicable form, certificate or document prescribed by the IRS or the United States certifying as to such Foreign Lender's entitlement to such exemption (a "CERTIFICATE OF EXEMPTION"). Any foreign Person that seeks to become a Lender under this Agreement shall provide a Certificate of Exemption to Borrower and Agent prior to becoming a Lender hereunder. No foreign Person may become a Lender hereunder if such Person fails to deliver a Certificate of Exemption in advance of becoming a Lender. 1.16 CAPITAL ADEQUACY; INCREASED COSTS; ILLEGALITY. (a) If any Lender shall have determined that any law, treaty, governmental (or quasi-governmental) rule, regulation, guideline or order regarding capital adequacy, reserve requirements or similar requirements or compliance by any Lender with any request or directive regarding capital adequacy, reserve requirements or similar requirements (whether or not having the force of law), in each case, adopted after the Closing Date, from any central bank or other Governmental Authority increases or would have the effect of increasing the amount of capital, reserves or other funds required to be maintained by such Lender and thereby reducing the rate of return on such Lender's capital as a consequence of its obligations hereunder, then Borrower shall from time to time upon demand by such Lender (with a copy of such demand to Agent) pay to Agent, for the account of such Lender, additional amounts sufficient to compensate such Lender for such reduction. A certificate as to the amount of that reduction and showing the basis of the computation thereof submitted by such Lender to Borrower and to Agent shall, absent manifest error, be final, conclusive and binding for all purposes. (b) If, due to either (i) the introduction of or any change in any law or regulation (or any change in the interpretation thereof) or (ii) the compliance with any guideline or request from any central bank or other Governmental Authority (whether or not having the force of law), in each case adopted after the Closing Date, there shall be any increase in the cost to any Lender of agreeing to make or making, funding or maintaining any Loan, then Borrower shall from time to time, upon demand by such Lender (with a copy of such demand to Agent), pay to Agent for the account of such Lender additional amounts sufficient to compensate such Lender for such increased cost. A certificate as to the amount of such increased cost, submitted to Borrower and to Agent by such Lender, shall be conclusive and binding on Borrower for all purposes, absent manifest error. Each Lender agrees that, as promptly as practicable after it becomes aware of any circumstances referred to above which would result in any such increased cost, the affected Lender shall, to the extent not inconsistent with such Lender's internal policies of general application, use reasonable commercial efforts to minimize costs and expenses incurred by it and payable to it by Borrower pursuant to this SECTION 1.16(b). (c) Notwithstanding anything to the contrary contained herein, if the introduction of or any change in any law or regulation (or any change in the interpretation thereof) shall make it unlawful, or any central bank or other Governmental Authority shall assert that it is unlawful, for any Lender to agree to make or to make or to continue to fund or maintain any LIBOR Loan, then, unless that Lender is able to make or to continue to fund or to maintain such LIBOR Loan at another branch or office of that Lender without, in that Lender's opinion, 21

adversely affecting it or its Loans or the income obtained therefrom, on notice thereof and demand therefor by such Lender to Borrower through Agent, (i) the obligation of such Lender to agree to make or to make or to continue to fund or maintain LIBOR Loans shall terminate and (ii) Borrower shall forthwith prepay in full all outstanding LIBOR Loans owing to such Lender, together with interest accrued thereon, UNLESS Borrower, within 5 Business Days after the delivery of such notice and demand, converts all LIBOR Loans into Index Rate Loans. (d) Within 15 days after receipt by Borrower of written notice and demand from any Lender (an "AFFECTED LENDER") for payment of additional amounts or increased costs as provided in SECTIONS 1.15(a), 1.16(a) OR 1.16(b), Borrower may, at its option, notify Agent and such Affected Lender of its intention to replace the Affected Lender. So long as no Default or Event of Default has occurred and is continuing, Borrower, with the consent of Agent, may obtain, at Borrower's expense, a replacement Lender ("REPLACEMENT LENDER") for the Affected Lender, which Replacement Lender must be reasonably satisfactory to Agent. If Borrower obtains a Replacement Lender within 90 days following notice of its intention to do so, the Affected Lender must sell and assign its Loans and Commitments to such Replacement Lender for an amount equal to the principal balance of all Loans held by the Affected Lender and all accrued interest and Fees with respect thereto through the date of such sale; PROVIDED, that Borrower shall have reimbursed such Affected Lender for the additional amounts or increased costs that it is entitled to receive under this Agreement through the date of such sale and assignment. Notwithstanding the foregoing, Borrower shall not have the right to obtain a Replacement Lender if the Affected Lender rescinds its demand for increased costs or additional amounts within 15 days following its receipt of Borrower's notice of intention to replace such Affected Lender. Furthermore, if Borrower gives a notice of intention to replace and does not so replace such Affected Lender within 90 days thereafter, Borrower's rights under this SECTION 1.16(d) shall terminate and Borrower shall promptly pay all increased costs or additional amounts demanded by such Affected Lender pursuant to SECTIONS 1.15(a), 1.16(a) AND 1.16(b). 1.17 SINGLE LOAN. All Loans to Borrower and all of the other Obligations of Borrower arising under this Agreement and the other Loan Documents shall constitute one general obligation of Borrower secured, until the Termination Date, by all of the Collateral. 2. CONDITIONS PRECEDENT 2.1 CONDITIONS TO THE INITIAL LOANS. No Lender shall be obligated to make any Loan or incur any Letter of Credit Obligations on the Closing Date, or to take, fulfill, or perform any other action hereunder, until the following conditions have been satisfied or provided for in a manner satisfactory to Agent, or waived in writing by Agent and Lenders: (a) CREDIT AGREEMENT; LOAN DOCUMENTS. This Agreement or counterparts hereof shall have been duly executed by, and delivered to, Borrower, each other Credit Party, Agent and Lenders; and Agent shall have received such documents, instruments, agreements and 22

that restricts or limits its ability to incur Indebtedness or to perform its obligations hereunder. The making of the Loans by Lenders to Borrower, the incurrence of the Letter of Credit Obligations on behalf of Borrower, the application of the proceeds thereof and repayment thereof and the consummation of the Related Transactions will not violate any provision of any such statute or any rule, regulation or order issued by the Securities and Exchange Commission (or applicable foreign equivalent or similar regulatory body). 3.10 MARGIN REGULATIONS. No Credit Party is engaged, nor will it engage, principally or as one of its important activities, in the business of extending credit for the purpose of "purchasing" or "carrying" any "margin stock" as such terms are defined in Regulation U of the Federal Reserve Board as now and from time to time hereafter in effect (such securities being referred to herein as "MARGIN STOCK"). No Credit Party owns any Margin Stock, and none of the proceeds of the Loans or other extensions of credit under this Agreement will be used, directly or indirectly, for the purpose of purchasing or carrying any Margin Stock, for the purpose of reducing or retiring any Indebtedness that was originally incurred to purchase or carry any Margin Stock or for any other purpose that might cause any of the Loans or other extensions of credit under this Agreement to be considered a "purpose credit" within the meaning of Regulations T, U or X of the Federal Reserve Board. No Credit Party will take or permit to be taken any action that might cause any Loan Document to violate any regulation of the Federal Reserve Board. 3.11 TAXES. All tax returns, reports and statements, including information returns, required by any Governmental Authority to be filed by any Credit Party have been filed with the appropriate Governmental Authority and all Charges have been paid prior to the date on which any fine, penalty, interest or late charge may be added thereto for nonpayment thereof (or any such fine, penalty, interest, late charge or loss has been paid), excluding Charges or other amounts being contested in accordance with SECTION 5.2(b).

Except as described in DISCLOSURE SCHEDULE (3.11), no Credit Party has executed or filed with the IRS or any other Governmental Authority any agreement or other document extending, or having the effect of extending, the period for assessment or collection of any Charges. None of the Credit Parties and their respective predecessors are liable for any Charges: (a) under any agreement (including any tax sharing agreements) or (b) to each Credit Party's knowledge, as a transferee. As of the Closing Date, no Credit Party has agreed or been requested to make any adjustment under IRC Section 481(a), by reason of a change in accounting method or otherwise, which would have a Material Adverse Effect. 30

Copies of all such listed Plans, together with a copy of the latest IRS/DOL form 5500-series for each such Plan, if applicable, have been delivered to Agent. Except with respect to Multiemployer Plans, each Qualified Plan has been determined by the IRS to qualify under Section 401 of the IRC, the trusts created thereunder have been determined to be exempt from tax under the provisions of Section 501 of the IRC, and nothing has occurred that would cause the loss of such qualification or tax-exempt status. Each Plan is in material compliance with the applicable provisions of ERISA and the IRC, including the timely filing of all reports required under the IRC or ERISA, including the statement required by 29 CFR Section 2520.104-23. Neither any Credit Party nor ERISA Affiliate has failed to make any contribution or pay any amount due as required by either Section 412 of the IRC or Section 302 of ERISA or the terms of any such Plan. Neither any Credit Party nor ERISA Affiliate has engaged in a "prohibited transaction," as defined in Section 406 of ERISA and Section 4975 of the IRC, in connection with any Plan, that would subject any Credit Party to a material tax on prohibited transactions imposed by Section 502(i) of ERISA or Section 4975 of the IRC. (b) Except as set forth in DISCLOSURE SCHEDULE (3.12): (i) no Title IV Plan has any Unfunded Pension Liability; (ii) no ERISA Event or event described in Section 4062(e) of ERISA with respect to any Title IV Plan has occurred or is reasonably expected to occur; (iii) there are no pending, or to the knowledge of any Credit Party, threatened claims (other than claims for benefits in the normal course), sanctions, actions or lawsuits, asserted or instituted against any Plan or any Person as fiduciary or sponsor of any Plan; (iv) no Credit Party or ERISA Affiliate has incurred or reasonably expects to incur any liability as a result of a complete or partial withdrawal from a Multiemployer Plan; (v) within the last five years no Title IV Plan of any Credit Party or ERISA Affiliate has been terminated, whether or not in a "standard termination" as that term is used in Section 404(b)(1) of ERISA, nor has any Title IV Plan of any Credit Party or ERISA Affiliate (determined at any time within the past five years) with Unfunded Pension Liabilities been transferred outside of the "controlled group" (within the meaning of Section 4001(a)(14) of ERISA) of any Credit Party or ERISA Affiliate; (vi) except in the case of any ESOP, Stock of all Credit Parties and their ERISA Affiliates makes up, in the aggregate, no more than 10% of fair market value of the assets of any Plan measured on the basis of fair market value as of the latest valuation date of any Plan; and (vii) no liability under any Title IV Plan has been satisfied with the purchase of a contract from an insurance company that is not rated AAA by the Standard & Poor's Corporation or an equivalent rating by another nationally recognized rating agency. The Canadian Pension Plans are duly registered under the ITA and all other applicable laws which require registration and no event has occurred which is reasonably likely to cause the loss of such registered status. All obligations of WESCO-Canada (including fiduciary, funding, investment and administration obligations) required to be performed in connection with the Canadian Pension Plans and the funding agreements therefor have been performed in a timely fashion. There have been no improper withdrawals or applications of the assets of the Canadian Pension Plans or the Canadian Benefit Plans.

forth in this SECTION 5.2(b) are no longer met, and (v) Agent has not advised Borrower in writing that Agent reasonably believes that nonpayment or nondischarge thereof could have or result in a Material Adverse Effect. 5.3 BOOKS AND RECORDS.

(a) The Credit Parties shall, at their sole cost and expense, maintain the policies of insurance described on DISCLOSURE SCHEDULE (3.18) as in effect on the date hereof or otherwise in form and amounts and with insurers reasonably acceptable to Agent. Such policies of insurance (or the loss payable and additional insured endorsements delivered to Agent) shall contain provisions pursuant to which the insurer agrees to provide 30 days prior written notice to Agent in the event of any non-renewal, cancellation or amendment of any such insurance policy. If any Credit Party at any time or times hereafter shall fail to obtain or maintain any of the policies of insurance required above or to pay all premiums relating thereto, Agent may at any time or times thereafter obtain and maintain such policies of insurance and pay such premiums and take any other action with respect thereto that Agent deems advisable. Agent shall have no obligation to obtain insurance for any Credit Party or pay any premiums therefor. By doing so, Agent shall not be deemed to have waived any Default or Event of Default arising from any Credit Party's failure to maintain such insurance or pay any premiums therefor. All sums so disbursed, including reasonable attorneys' fees, court costs and other charges related thereto, shall be payable on demand by Borrower to Agent and shall be additional Obligations hereunder secured by the Collateral. (b) Agent reserves the right at any time upon any change in any Credit Party's risk profile (including any change in the product mix maintained by any Credit Party or any laws affecting the potential liability of such Credit Party) to require additional forms and limits of insurance to, in Agent's opinion, adequately protect both Agent's and Lender's interests in all or any portion of the Collateral and to ensure that each Credit Party is protected by insurance in amounts and with coverage customary for its industry. If reasonably requested by Agent, each Credit Party shall deliver to Agent from time to time a report of a reputable insurance broker, selected by Borrower and reasonably satisfactory to Agent, with respect to its insurance policies. (c) Each Credit Party shall deliver to Agent, in form and substance reasonably satisfactory to Agent, endorsements to (i) all "All Risk" and business interruption insurance naming Agent, on behalf of itself and Lenders, as loss payee, and (ii) all general liability and 37

other liability policies naming Agent, on behalf of itself and Lenders, as additional insured. Each Credit Party irrevocably makes, constitutes and appoints Agent (and all officers, employees or agents designated by Agent), so long as any Default or Event of Default has occurred and is continuing or the anticipated insurance proceeds exceed $1,000,000, as each Credit Party's true and lawful agent and attorney-in-fact for the purpose of making, settling and adjusting claims under such "All Risk" policies of insurance, endorsing the name of each Credit Party on any check or other item of payment for the proceeds of such "All Risk" policies of insurance and for making all determinations and decisions with respect to such "All Risk" policies of insurance. Agent shall have no duty to exercise any rights or powers granted to it pursuant to the foregoing power-of- attorney. Borrower shall promptly notify Agent of any loss, damage, or destruction to the Collateral in the amount of $500,000 or more, whether or not covered by insurance. After deducting from such proceeds the expenses, if any, incurred by Agent in the collection or handling thereof, Agent may, at its option, apply such proceeds to the reduction of the Obligations in accordance with SECTION 1.3(d), PROVIDED that in the case of insurance proceeds pertaining to any Credit Party other than Borrower, such insurance proceeds shall be applied to the Loans owing by Borrower, or permit or require each Credit Party to use such money, or any part thereof, to replace, repair, restore or rebuild the Collateral in a diligent and expeditious manner with materials and workmanship of substantially the same quality as existed before the loss, damage or destruction. Notwithstanding the foregoing, if the casualty giving rise to such insurance proceeds could not reasonably be expected to have a Material Adverse Effect and such insurance proceeds do not exceed $1,000,000 in the aggregate, Agent shall permit the applicable Credit Party to replace, restore, repair or rebuild the property; PROVIDED that if such Credit Party has not completed or entered into binding agreements to complete such replacement, restoration, repair or rebuilding within 180 days of such casualty, Agent may apply such insurance proceeds to the Obligations in accordance with SECTION 1.3(d); PROVIDED further that in the case of insurance proceeds pertaining to any Credit Party other than Borrower, such insurance proceeds shall be applied to the Loans owing by Borrower. All insurance proceeds that are to be made available to Borrower to replace, repair, restore or rebuild the Collateral shall be applied by Agent to reduce the outstanding principal balance of the Revolving Loan (which application shall not result in a permanent reduction of the Revolving Loan Commitment) and upon such application, Agent shall establish a Reserve against the Borrowing Base in an amount equal to the amount of such proceeds so applied. All insurance proceeds made available to any Credit Party that is not a Borrower to replace, repair, restore or rebuild Collateral shall be deposited in a cash collateral account. Thereafter, such funds shall be made available to such Credit Party to provide funds to replace, repair, restore or rebuild the Collateral as follows: (i) Borrower shall request a Revolving Credit Advance or release from the cash collateral account be made to Borrower or such other Credit Party, as the case may be, in the amount requested to be released; (ii) so long as the conditions set forth in SECTION 2.2 have been met, Lenders shall make such Revolving Credit Advance or Agent shall release funds from the cash collateral account; and (iii) in the case of insurance proceeds applied against the Revolving Loan, the Reserve established with respect to such insurance proceeds shall be reduced by the amount of such Revolving Credit Advance. To the extent not used to replace, repair, restore or rebuild the Collateral, such insurance proceeds shall be applied in accordance with SECTION 1.3(d); PROVIDED that in the case of insurance proceeds pertaining to any Credit Party other than Borrower, such insurance proceeds shall be applied to the Loans owing by Borrower. 38

5.5 COMPLIANCE WITH LAWS. Each Credit Party shall comply with all federal, state, local, Canadian, provincial and foreign laws and regulations applicable to it, including those relating to ERISA and labor matters and Environmental Laws and Environmental Permits, except to the extent that the failure to comply, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect. 5.6 SUPPLEMENTAL DISCLOSURE. From time to time as may be reasonably requested by Agent (which request will not be made more frequently than once each year absent the occurrence and continuance of a Default or an Event of Default), the Credit Parties shall supplement each Disclosure Schedule hereto, or any representation herein or in any other Loan Document, with respect to any matter hereafter arising that, if existing or occurring at the date of this Agreement, would have been required to be set forth or described in such Disclosure Schedule or as an exception to such representation or that is necessary to correct any information in such Disclosure Schedule or representation which has been rendered inaccurate thereby (and, in the case of any supplements to any Disclosure Schedule, such Disclosure Schedule shall be appropriately marked to show the changes made therein); PROVIDED that (a) no such supplement to any such Disclosure Schedule or representation shall amend, supplement or otherwise modify any Disclosure Schedule or representation, or be or be deemed a waiver of any Default or Event of Default resulting from the matters disclosed therein, except as consented to by Agent and Requisite Lenders in writing, and (b) no supplement shall be required or permitted as to representations and warranties that relate solely to the Closing Date. 5.7 INTELLECTUAL PROPERTY. Each Credit Party will conduct its business and affairs without infringement of or interference with any Intellectual Property of any other Person in any material respect. 5.8 ENVIRONMENTAL MATTERS. Each Credit Party shall and shall cause each Person within its control to: (a) conduct its operations and keep and maintain its Real Estate in compliance with all Environmental Laws and Environmental Permits other than noncompliance that could not reasonably be expected to have a Material Adverse Effect; (b) implement any and all investigation, remediation, removal and response actions that are appropriate or necessary to maintain the value and marketability of the Real Estate or to otherwise comply with Environmental Laws and Environmental Permits pertaining to the presence, generation, treatment, storage, use, disposal, transportation or Release of any Hazardous Material on, at, in, under, above, to, from or about any of its Real Estate; (c) notify Agent promptly after such Credit Party becomes aware of any violation of Environmental Laws or Environmental Permits or any Release on, at, in, under, above, to, from or about any Real Estate that is reasonably likely to result in Environmental Liabilities in excess of $250,000; and (d) promptly forward to Agent a copy of any order, notice, request for information or any communication or report received by 39

such Credit Party in connection with any such violation or Release or any other matter relating to any Environmental Laws or Environmental Permits that could reasonably be expected to result in Environmental Liabilities in excess of $250,000, in each case whether or not the Environmental Protection Agency or any Governmental Authority has taken or threatened any action in connection with any such violation, Release or other matter. If Agent at any time has a reasonable basis to believe that there may be a violation of any Environmental Laws or Environmental Permits by any Credit Party or any Environmental Liability arising thereunder, or a Release of Hazardous Materials on, at, in, under, above, to, from or about any of its Real Estate, that, in each case, could reasonably be expected to have a Material Adverse Effect, then each Credit Party shall, upon Agent's written request (i) cause the performance of such environmental audits including subsurface sampling of soil and groundwater, and preparation of such environmental reports, at Borrower's expense, as Agent may from time to time reasonably request, which shall be conducted by reputable environmental consulting firms reasonably acceptable to Agent and shall be in form and substance reasonably acceptable to Agent, and (ii) permit Agent or its representatives to have access to all Real Estate for the purpose of conducting such environmental audits and testing as Agent deems appropriate, including subsurface sampling of soil and groundwater. Borrower shall reimburse Agent for the costs of such audits and tests and the same will constitute a part of the Obligations secured hereunder. 5.9 LANDLORDS' AGREEMENTS, MORTGAGEE AGREEMENTS, BAILEE LETTERS AND REAL ESTATE PURCHASES. Each Credit Party shall use all commercially reasonable efforts to obtain a landlord's agreement, mortgagee agreement or bailee letter, as applicable, from the lessor of each leased property, mortgagee of owned property or bailee with respect to any warehouse, processor or converter facility or other location where Collateral is stored or located as of the Closing Date and as may be stored or located thereafter, which agreement or letter shall contain a waiver or subordination of all Liens or claims that the landlord, mortgagee or bailee may assert against the Collateral at that location, and shall otherwise be reasonably satisfactory in form and substance to Agent. With respect to such locations or warehouse space leased or owned following the Closing Date (specifically excluding such locations or warehouse space leased or owned as of the Closing Date), if Agent has not received a landlord or mortgagee agreement or bailee letter as of the date such location is acquired or leased, Borrower's, WESCO Equity's, Herning's or WESCO-Canada's Eligible Inventory at that location shall, in Agent's discretion, be subject to such Reserves as may be established by Agent in its reasonable credit judgment. Each Credit Party shall use all commercially reasonable efforts to obtain a collateral access agreement from each customer which has any Collateral of any Credit Party located at its facilities (whether such facilities are owned or leased by such customer), which agreement shall contain a waiver or subordination of all Liens or claims that such customer may assert against the Collateral, provide for a release of all Liens by any other party, if any, provide for a consent and acknowledgment to the ownership and Lien of Borrower and Lien of Agent, in its favor and on behalf of Lenders, in the Collateral, provide for the segregation of all Collateral from any personal property or other assets of such customer, provide for all such UCC filings deemed necessary or desirable by Agent and shall otherwise be satisfactory in form and substance to Agent. After the Closing Date, no real property or warehouse space shall be leased by any Credit Party and no Inventory shall be shipped to a processor or converter under arrangements established after the Closing 40

Date unless and until a satisfactory landlord agreement or bailee letter, as appropriate, shall first have been obtained with respect to such location or Agent, in its reasonable credit judgment, shall have established an appropriate Reserve, if any. If Agent has not received a collateral access agreement with respect to any customer location, Borrower's, WESCO Equity's, Herning's or WESCO-Canada's Inventory at such customer location shall not be Eligible Inventory and shall not be eligible for inclusion in any calculation of the Borrowing Base or Borrowing Availability. Each Credit Party shall timely and fully pay and perform its rent and other obligations under all leases and other agreements with respect to each leased location or public warehouse where any Collateral is or may be located. Agent reserves the right, in its discretion, to establish Reserves acceptable to Agent, in its reasonable credit judgment with respect to any leased property, any warehouse, processor or converter facility, or any other location where Collateral is stored or located as of the Closing Date or as may be acquired or leased thereafter. In no event shall any Inventory stored or otherwise located at any customer location be considered Eligible Inventory or be otherwise eligible for inclusion in any calculation of the Borrowing Base or Borrowing Availability unless Agent shall have received a collateral access agreement acceptable to it and any and all other actions deemed necessary or desirable by Agent (e.g. UCC filings) shall have been taken. 5.10 COVENANTS REGARDING ACCOUNTS. In the ordinary course of its business, each Credit Party processes its Accounts in a manner such that (i) each payment received by such Credit Party in respect of an Account is allocated to a specifically identified invoice, which invoice corresponds to a particular Account owing to such Credit Party and (ii) in the event that, at any time, less than 100% of the Account of such Credit Party are included in a Permitted Receivables Financing, payments received in respect of those Accounts included in a Permitted Receivables Financing would be identifiable and separable from payments received in respect of Accounts not so included in a Permitted Receivables Financing. WESCO-Canada shall not at any time enter into a Permitted Receivables Financing or any other similar financing or transaction. 5.11 CANADIAN PENSION AND BENEFIT PLANS. (a) For each existing Canadian Pension Plan, each Credit Party shall ensure that such plan retains its registered status under and is administered in a timely manner in all material respects in accordance with the applicable pension plan text, funding agreement, the ITA and all other applicable laws. (b) For each Canadian Pension Plan hereafter adopted by any Credit Party which is required to be registered under the ITA or any other applicable laws, that Credit Party shall use all commercially reasonable efforts to seek and receive confirmation in writing from the applicable Governmental Authorities to the effect that such plan is unconditionally registered under the ITA and such other applicable laws. (c) For each existing and hereafter adopted Canadian Pension Plan and Canadian Benefit Plan, each Credit Party shall in a timely fashion perform in all material respects 41

all obligations (including fiduciary, funding, investment and administration obligations) required to be performed in connection with such plan and the funding media therefor. (d) Each Credit Party shall deliver to Agent if requested by Agent, promptly after the filing thereof by any Credit Party with any applicable Governmental Authority, (i) copies of each annual and other return, report or valuation with respect to each Canadian Pension Plan; (ii) promptly after receipt thereof, a copy of any direction, order, notice, ruling or opinion that any Credit Party may receive from any applicable Governmental Authority with respect to any Canadian Pension Plan; and (iii) notification within 30 days of any increases having a cost to such Credit Party in excess of Canadian $250,000, or the Dollar Equivalent Amount thereof, per annum, in the benefits of any existing Canadian Pension Plan or Canadian Benefit Plan, or the establishment of any new Canadian Pension Plan or Canadian Benefit Plan, or the commencement of contributions to any such plan to which any Credit Party was not previously contributing. 5.12 FURTHER ASSURANCES. Each Credit Party executing this Agreement agrees that it shall and shall cause each other Credit Party to, at such Credit Party's expense and upon request of Agent, duly execute and deliver, or cause to be duly executed and delivered, to Agent such further instruments and do and cause to be done such further acts as may be necessary or proper in the reasonable opinion of Agent to carry out more effectively the provisions and purposes of this Agreement or any other Loan Document. 6.

ASSIGNMENT AND PARTICIPATIONS; APPOINTMENT OF AGENT 9.1 ASSIGNMENT AND PARTICIPATIONS.

Any assignment by a Lender shall: (i) require the consent of Agent and, so long as no Default or Event of Default has occurred and is continuing, the Borrower, which consent shall not be unreasonably withheld or delayed with respect to a Qualified Assignee and the execution of an assignment agreement (an "ASSIGNMENT AGREEMENT" substantially in the form attached hereto as EXHIBIT 9.1(a) and otherwise in form and substance reasonably satisfactory to, and acknowledged by, Agent; (ii) be conditioned on such assignee Lender representing to the assigning Lender and Agent that it is purchasing the applicable Loans to be assigned to it for its own account, for investment purposes and not with a view to the distribution thereof; (iii) after giving effect to any such partial assignment, the assignee Lender shall have Commitments in an amount at least equal to $5,000,000 and the assigning Lender shall have retained Commitments in an amount at least equal to $5,000,000; and (iv) include a payment to Agent of an assignment fee of $3,500. In the case of an assignment by a Lender under this SECTION 9.1, the assignee shall 64

have, to the extent of such assignment, the same rights, benefits and obligations as all other Lenders hereunder. The assigning Lender shall be relieved of its obligations hereunder with respect to its Commitments or assigned portion thereof from and after the date of such assignment. Borrower hereby acknowledges and agrees that any assignment shall give rise to a direct obligation of Borrower to the assignee and that the assignee shall be considered to be a "Lender". In all instances, each Lender's liability to make Loans hereunder shall be several and not joint and shall be limited to such Lender's Pro Rata Share of the applicable Commitment. In the event Agent or any Lender assigns or otherwise transfers all or any part of the Obligations, Agent or any such Lender shall so notify Borrower and Borrower shall, upon the request of Agent or such Lender, execute new Notes in exchange for the Notes, if any, being assigned. Notwithstanding the foregoing provisions of this SECTION 9.1(a), any Lender may at any time pledge the Obligations held by it and such Lender's rights under this Agreement and the other Loan Documents to a Federal Reserve Bank, and any lender that is an investment fund may assign the Obligations held by it and such Lender's rights under this Agreement and the other Loan Documents to another investment fund managed by the same investment advisor; PROVIDED, that no such pledge to a Federal Reserve Bank shall release such Lender from such Lender's obligations hereunder or under any other Loan Document. Any foreign Person that seeks to become a Lender under this Agreement shall provide a Certificate of Exemption to Borrower and Agent prior to becoming a Lender hereunder. No foreign Person may become a Lender hereunder if such Person fails to deliver a Certificate of Exemption in advance of becoming a Lender. (b) Any participation by a Lender of all or any part of its Commitments shall be made with the understanding that all amounts payable by Borrower hereunder shall be determined as if that Lender had not sold such participation, and that the holder of any such participation shall not be entitled to require such Lender to take or omit to take any action hereunder except actions directly affecting (i) any reduction in the principal amount of, or interest rate or Fees payable with respect to, any Loan in which such holder participates, (ii) any extension of the scheduled amortization of the principal amount of any Loan in which such holder participates or the final maturity date thereof, and (iii) any release of all or substantially all of the Collateral (other than in accordance with the terms of this Agreement, the Collateral Documents or the other Loan Documents). Solely for purposes of SECTIONS 1.13, 1.15, 1.16 and 9.8, Borrower acknowledges and agrees that a participation shall give rise to a direct obligation of Borrower to the participant and the participant shall be considered to be a "Lender". Except as set forth in the preceding sentence neither Borrower nor any other Credit Party shall have any obligation or duty to any participant. Neither Agent nor any Lender (other than the Lender selling a participation) shall have any duty to any participant and may continue to deal solely with the Lender selling a participation as if no such sale had occurred. (c) Except as expressly provided in this SECTION 9.1, no Lender shall, as between Borrower and that Lender, or Agent and that Lender, be relieved of any of its obligations hereunder as a result of any sale, assignment, transfer or negotiation of, or granting of participation in, all or any part of the Loans, the Notes or other Obligations owed to such Lender. (d) Each Credit Party executing this Agreement shall assist any Lender permitted to sell assignments or participations under this SECTION 9.1 as reasonably required to 65

enable the assigning or selling Lender to effect any such assignment or participation, including the execution and delivery of any and all agreements, notes and other documents and instruments as shall be requested and the preparation of informational materials for, and the participation of management in meetings with, potential assignees or participants. Each Credit Party executing this Agreement shall certify the correctness, completeness and accuracy of all descriptions of the Credit Parties and their respective affairs contained in any selling materials provided by it and all other information provided by it and included in such materials, except that any Projections delivered by Borrower shall only be certified by Borrower as having been prepared by Borrower in compliance with the representations contained in SECTION 3.4(c). (e) A Lender may furnish any information concerning Credit Parties in the possession of such Lender from time to time to assignees and participants (including prospective assignees and participants); provided that such Lender shall obtain from assignees or participants confidentiality covenants substantially equivalent to those contained in SECTION 11.8. (f) So long as no Event of Default has occurred and is continuing, no Lender shall assign or sell participations in any portion of its Loans or Commitments to a potential Lender or participant, if, as of the date of the proposed assignment or sale, the assignee Lender or participant would be subject to capital adequacy or similar requirements under SECTION 1.16(a), increased costs under SECTION 1.16(b), an inability to fund LIBOR Loans under SECTION 1.16(c), or withholding taxes in accordance with SECTION 1.15(a). (g) Notwithstanding anything to the contrary contained herein, any Lender (a "Granting Lender"), may grant to a special purpose funding vehicle (an "SPC"), identified as such in writing by the Granting Lender to Agent and Borrower, the option to provide to Borrower all or any part of any Loans that such Granting Lender would otherwise be obligated to make to Borrower pursuant to this Agreement; PROVIDED THAT (i) nothing herein shall constitute a commitment by any SPC to make any Loan; and (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Loan, the Granting Lender shall be obligated to make such Loan pursuant to the terms hereof. The making of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if such Loan were made by such Granting Lender. No SPC shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Lender). Any SPC may (i) with notice to, but without the prior written consent of, Borrower and Agent and after paying any processing fee therefor assign all or a portion of its interests in any Loans to the Granting Lender or to any financial institutions (consented to by Borrower and Agent) providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Loans and (ii) disclose on a confidential basis any non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC. This SECTION 9.1(g) may not be amended without the prior written consent of each Granting Lender, all or any of whose Loans are being funded by an SPC at the time of such amendment. For the avoidance of doubt, the Granting Lender shall for all purposes, including without limitation, the approval of any amendment or waiver of any provision of any Loan Document or the obligation to pay any amount otherwise payable by the Granting Lender under the Loan Documents, continue to be the Lender of record hereunder. 66

Except as expressly set forth in this Agreement and the other Loan Documents, Agent shall not have any duty to disclose, and shall not be liable for failure to disclose, any information relating to any Credit Party or any of their respective Subsidiaries or any Account Debtor that is communicated to or obtained by GE Capital or any of its Affiliates in any capacity. Neither Agent nor any of its Affiliates nor any of their respective officers, directors, employees, agents or representatives shall be liable to any Lender for any action taken or omitted to be taken by it hereunder or under any other Loan Document, or in connection herewith or therewith, except for damages caused by its or their own gross negligence or willful misconduct. Without limiting any of the foregoing provisions in favor of Agent, for the purposes of holding any security granted by any Credit Party pursuant to the laws of the Province of Quebec, including any deed of hypothec, debenture, bond or other title of indebtedness and debenture or bond pledge agreements, Agent is hereby appointed to act as the Person holding the power of attorney (fonde de pouvoir) pursuant to article 2692 of the Civil Code of Quebec to act on behalf of each present and future Lender. Each party hereto agrees that, notwithstanding Section 32 of an Act respecting the Special Powers of Legal Persons (Quebec), Agent may, as the Person holding the power of attorney of the Lenders, acquire and or be the pledgee of any debentures, bonds or other titles of indebtedness secured by any hypothec granted by any Credit Party to the Agent pursuant to the laws of the Province of Quebec. If Agent shall request instructions from Requisite Lenders, Supermajority Lenders or all affected Lenders with respect to any act or action (including failure to act) in connection with this Agreement or any other Loan Document, then Agent shall be entitled to refrain from such act or taking such action unless and until Agent shall have received instructions from Requisite Lenders, Requisite Lenders, Supermajority Lenders, or all affected Lenders, as the case may be, and Agent shall not incur liability to any Person by reason of so refraining. Agent shall be fully justified in failing or refusing to take any action hereunder or under any other Loan Document (a) if such action would, in the opinion of Agent, be contrary to law or the terms of this Agreement or any other Loan Document, (b) if such action would, in the opinion of Agent, expose Agent to Environmental Liabilities or (c) if Agent shall not first be indemnified to its satisfaction against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. Without limiting the foregoing, no Lender shall have any right of action whatsoever against Agent as a result of Agent acting or refraining from 67

acting hereunder or under any other Loan Document in accordance with the instructions of Requisite Lenders, Supermajority Lenders or all affected Lenders, as applicable. 9.3 AGENT'S RELIANCE, ETC. Neither Agent nor any of its Affiliates nor any of their respective directors, officers, agents or employees shall be liable for any action taken or omitted to be taken by it or them under or in connection with this Agreement or the other Loan Documents, except for damages caused by its or their own gross negligence or willful misconduct. Without limiting the generality of the foregoing, Agent: (a) may treat the payee of any Note as the holder thereof until Agent receives written notice of the assignment or transfer thereof signed by such payee and in form reasonably satisfactory to Agent; (b) may consult with legal counsel, independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the advice of such counsel, accountants or experts; (c) makes no warranty or representation to any Lender and shall not be responsible to any Lender for any statements, warranties or representations made in or in connection with this Agreement or the other Loan Documents; (d) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of this Agreement or the other Loan Documents on the part of any Credit Party or to inspect the Collateral (including the books and records) of any Credit Party; (e) shall not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or the other Loan Documents or any other instrument or document furnished pursuant hereto or thereto; and (f) shall incur no liability under or in respect of this Agreement or the other Loan Documents by acting upon any notice, consent, certificate or other instrument or writing (which may be by telecopy, telegram, cable or telex) believed by it to be genuine and signed or sent by the proper party or parties. 9.4 GE CAPITAL AND AFFILIATES. With respect to its Commitments hereunder, GE Capital shall have the same rights and powers under this Agreement and the other Loan Documents as any other Lender and may exercise the same as though it were not Agent; and the term "Lender" or "Lenders" shall, unless otherwise expressly indicated, include GE Capital in its individual capacity. GE Capital and its Affiliates may lend money to, invest in, and generally engage in any kind of business with, any Credit Party, any of their Affiliates and any Person who may do business with or own securities of any Credit Party or any such Affiliate, all as if GE Capital were not Agent and without any duty to account therefor to Lenders. GE Capital and its Affiliates may accept fees and other consideration from any Credit Party for services in connection with this Agreement or otherwise without having to account for the same to Lenders. Each Lender acknowledges the potential conflict of interest between GE Capital as a Lender holding disproportionate interests in the Loans and GE Capital as Agent. 9.5 LENDER CREDIT DECISION. Each Lender acknowledges that it has, independently and without reliance upon Agent or any other Lender and based on the Financial Statements referred to in SECTION 3.4(a) 68

and such other documents and information as it has deemed appropriate, made its own credit and financial analysis of the Credit Parties and its own decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon 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 decisions in taking or not taking action under this Agreement. Each Lender acknowledges the potential conflict of interest of each other Lender as a result of Lenders holding disproportionate interests in the Loans, and expressly consents to, and waives any claim based upon, such conflict of interest. 9.6 INDEMNIFICATION. Lenders agree to indemnify Agent (to the extent not reimbursed by Credit Parties and without limiting the obligations of Borrower hereunder), ratably according to their respective Pro Rata Shares, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever that may be imposed on, incurred by, or asserted against Agent in any way relating to or arising out of this Agreement or any other Loan Document or any action taken or omitted to be taken by Agent in connection therewith; PROVIDED, that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from Agent's gross negligence or willful misconduct. Without limiting the foregoing, each Lender agrees to reimburse Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including reasonable counsel fees) incurred by Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement and each other Loan Document, to the extent that Agent is not reimbursed for such expenses by Credit Parties. 9.7 SUCCESSOR AGENT. Agent may resign at any time by giving not less than 30 days' prior written notice thereof to Lenders and Borrower. Upon any such resignation, the Requisite Lenders shall have the right to appoint a successor Agent. If no successor Agent shall have been so appointed by the Requisite Lenders and shall have accepted such appointment within 30 days after the resigning Agent's giving notice of resignation, then the resigning Agent may, on behalf of Lenders, appoint a successor Agent, which shall be a Lender, if a Lender is willing to accept such appointment, or otherwise shall be a commercial bank or financial institution or a subsidiary of a commercial bank or financial institution if such commercial bank or financial institution is organized under the laws of the United States of America or of any State thereof and has a combined capital and surplus of at least $300,000,000. If no successor Agent has been appointed pursuant to the foregoing, within 30 days after the date such notice of resignation was given by the resigning Agent, such resignation shall become effective and the Requisite Lenders shall thereafter perform all the duties of Agent hereunder until such time, if any, as the Requisite Lenders appoint a successor Agent as provided above. Any successor Agent appointed by Requisite Lenders hereunder shall be subject to the approval of Borrower, such approval not to be unreasonably withheld or delayed; PROVIDED that such approval shall not be required if a Default or an Event of Default has occurred and is continuing. Upon the acceptance of any appointment as Agent 69

hereunder by a successor Agent, such successor Agent shall succeed to and become vested with all the rights, powers, privileges and duties of the resigning Agent. Upon the earlier of the acceptance of any appointment as Agent hereunder by a successor Agent or the effective date of the resigning Agent's resignation, the resigning Agent shall be discharged from its duties and obligations under this Agreement and the other Loan Documents, except that any indemnity rights or other rights in favor of such resigning Agent shall continue. After any resigning Agent's resignation hereunder, the provisions of this SECTION 9 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was acting as Agent under this Agreement and the other Loan Documents. 9.8 SETOFF AND SHARING OF PAYMENTS. In addition to any rights now or hereafter granted under applicable law and not by way of limitation of any such rights, upon the occurrence and during the continuance of any Event of Default and subject to SECTION 9.9(f), each Lender is hereby authorized at any time or from time to time, without notice to any Credit Party or to any other Person, any such notice being hereby expressly waived, to offset and to appropriate and to apply any and all balances held by it at any of its offices for the account of Borrower or any Guarantor (regardless of whether such balances are then due to Borrower or any Guarantor) and any other properties or assets at any time held or owing by that Lender or that holder to or for the credit or for the account of Borrower or any Guarantor against and on account of any of the Obligations that are not paid when due. Any Lender exercising a right of setoff or otherwise receiving any payment on account of the Obligations in excess of its Pro Rata Share thereof shall purchase for cash (and the other Lenders or holders shall sell) such participations in each such other Lender's or holder's Pro Rata Share of the Obligations as would be necessary to cause such Lender to share the amount so offset or otherwise received with each other Lender or holder in accordance with their respective Pro Rata Shares, (other than offset rights exercised by any Lender with respect to SECTIONS 1.13, 1.15 OR 1.16). Each Lender's obligation under this SECTION 9.8 shall be in addition to and not in limitation of its obligations to purchase a participation in an amount equal to its Pro Rata Share of the Swing Line Loans under SECTION 1.1. Borrower and each Guarantor agrees, to the fullest extent permitted by law, that (a) any Lender may exercise its right to offset with respect to amounts in excess of its Pro Rata Share of the Obligations and may sell participations in such amounts so offset to other Lenders and holders and (b) any Lender so purchasing a participation in the Loans made or other Obligations held by other Lenders or holders may exercise all rights of offset, bankers' lien, counterclaim or similar rights with respect to such participation as fully as if such Lender or holder were a direct holder of the Loans and the other Obligations in the amount of such participation. Notwithstanding the foregoing, if all or any portion of the offset amount or payment otherwise received is thereafter recovered from the Lender that has exercised the right of offset, the purchase of participations by that Lender shall be rescinded and the purchase price restored without interest. 70

9.9 ADVANCES; PAYMENTS; NON-FUNDING LENDERS; INFORMATION; ACTIONS IN CONCERT. (a) ADVANCES; PAYMENTS. (i) Lenders shall refund or participate in the Swing Line Loan in accordance with CLAUSES (iii) AND (iv) of SECTION 1.1(b). If the Swing Line Lender declines to make a Swing Line Loan or if Swing Line Availability is zero, Agent shall notify Lenders, promptly after receipt of a Notice of Revolving Advance and in any event prior to 1:00 p.m. (New York time) on the date such Notice of Revolving Advance is received, by telecopy, telephone or other similar form of transmission. Each Lender shall make the amount of such Lender's Pro Rata Share of such Revolving Credit Advance available to Agent in same day funds by wire transfer to Agent's account as set forth in ANNEX H not later than 3:00 p.m. (New York time) on the requested funding date, in the case of an Index Rate Loan and not later than 11:00 a.m. (New York time) on the requested funding date in the case of a LIBOR Loan. After receipt of such wire transfers (or, in the Agent's sole discretion, before receipt of such wire transfers), subject to the terms hereof, Agent shall make the requested Revolving Credit Advance to Borrower. All payments by each Lender shall be made without setoff, counterclaim or deduction of any kind. (ii) On the 2nd Business Day of each calendar week or more frequently at Agent's election (each, a "SETTLEMENT DATE"), Agent shall advise each Lender by telephone, or telecopy of the amount of such Lender's Pro Rata Share of principal, interest and Fees paid for the benefit of Lenders with respect to each applicable Loan. Provided that each Lender has funded all payments and Advances required to be made by it and purchased all participations required to be purchased by it under this Agreement and the other Loan Documents as of such Settlement Date, Agent shall pay to each Lender such Lender's Pro Rata Share of principal, interest and Fees paid by Borrower since the previous Settlement Date for the benefit of such Lender on the Loans held by it. To the extent that any Lender (a "Non-Funding Lender") has failed to fund all such payments and Advances or failed to fund the purchase of all such participations, Agent shall be entitled to set off the funding short-fall against that Non-Funding Lender's Pro Rata Share of all payments received from Borrower. Such payments shall be made by wire transfer to such Lender's account (as specified by such Lender in ANNEX H or the applicable Assignment Agreement) not later than 2:00 p.m. (New York time) on the next Business Day following each Settlement Date. (b) AVAILABILITY OF LENDER'S PRO RATA SHARE. Agent may assume that each Lender will make its Pro Rata Share of each Revolving Credit Advance available to Agent on each funding date. If such Pro Rata Share is not, in fact, paid to Agent by such Lender when due, Agent will be entitled to recover such amount on demand from such Lender without setoff, counterclaim or deduction of any kind. If any Lender fails to pay the amount of its Pro Rata Share forthwith upon Agent's demand, Agent shall promptly notify Borrower and Borrower shall immediately repay such amount to Agent. Nothing in this SECTION 9.9(b) or elsewhere in this Agreement or the other Loan Documents shall be deemed to require Agent to advance funds on behalf of any Lender or to relieve any Lender from its obligation to fulfill its Commitments hereunder or to prejudice any rights that Borrower may have against any Lender as a result of any 71

default by such Lender hereunder. To the extent that Agent advances funds to Borrower on behalf of any Lender and is not reimbursed therefor on the same Business Day as such Advance is made, Agent shall be entitled to retain for its account all interest accrued on such Advance until reimbursed by the applicable Lender. (c) RETURN OF PAYMENTS. (i) If Agent pays an amount to a Lender under this Agreement in the belief or expectation that a related payment has been or will be received by Agent from Borrower and such related payment is not received by Agent, then Agent will be entitled to recover such amount from such Lender on demand without setoff, counterclaim or deduction of any kind. (ii) If Agent determines at any time that any amount received by Agent under this Agreement must be returned to Borrower or paid to any other Person pursuant to any insolvency law or otherwise, then, notwithstanding any other term or condition of this Agreement or any other Loan Document, Agent will not be required to distribute any portion thereof to any Lender. In addition, each Lender will repay to Agent on demand any portion of such amount that Agent has distributed to such Lender, together with interest at such rate, if any, as Agent is required to pay to Borrower or such other Person, without setoff, counterclaim or deduction of any kind. (d) NON-FUNDING LENDERS. The failure of any Non-Funding Lender to make any Revolving Credit Advance or any payment required by it hereunder, or to purchase any participation in any Swing Line Loan to be made or purchased by it on the date specified therefor shall not relieve any other Lender (each such other Lender, an "OTHER LENDER") of its obligations to make such Advance or purchase such participation on such date, but neither any Other Lender nor Agent shall be responsible for the failure of any Non-Funding Lender to make an Advance, purchase a participation or make any other payment required hereunder. Notwithstanding anything set forth herein to the contrary, a Non-Funding Lender shall not have any voting or consent rights under or with respect to any Loan Document or constitute a "Lender" or a "Lender" (or be included in the calculation of "Requisite Lenders" or "Supermajority Lenders" hereunder) for any voting or consent rights under or with respect to any Loan Document. At Borrower's request, Agent or a Person acceptable to Agent shall have the right with Agent's consent and in Agent's sole discretion (but shall have no obligation) to purchase from any Non-Funding Lender, and each Non- Funding Lender agrees that it shall, at Agent's request, sell and assign to Agent or such Person, all of the Commitments of that Non-Funding Lender for an amount equal to the principal balance of all Loans held by such Non-Funding Lender and all accrued interest and fees with respect thereto through the date of sale, such purchase and sale to be consummated pursuant to an executed Assignment Agreement. (e) DISSEMINATION OF INFORMATION. Agent shall use reasonable efforts to provide Lenders with any notice of Default or Event of Default received by Agent from, or delivered by Agent to, any Credit Party, with notice of any Event of Default of which Agent has actually become aware and with notice of any action taken by Agent following any Event of Default, and, regardless of whether a Default or Event of Default is in existence, copies of any collateral audits and appraisals as Agent may have conducted; provided, that Agent shall not be 72

liable to any Lender for any failure to do so, except to the extent that such failure is attributable to Agent's gross negligence or willful misconduct. (f) ACTIONS IN CONCERT. Anything in this Agreement to the contrary notwithstanding, each Lender hereby agrees with each other Lender that no Lender shall take any action to protect or enforce its rights arising out of this Agreement or the Notes (including exercising any rights of setoff) without first obtaining the prior written consent of Agent or Requisite Lenders, it being the intent of Lenders that any such action to protect or enforce rights under this Agreement and the Notes shall be taken in concert and at the direction or with the consent of Agent or Requisite Lenders. 9.10 SYNDICATION AGENT AND DOCUMENTATION AGENT. The parties hereto acknowledge and agree that no Person shall have, by reason of its designation as Syndication Agent or Documentation Agent, any power, duty, responsibility or liability whatsoever under this Agreement or any other Loan Document. 10. SUCCESSORS AND ASSIGNS 10.1 SUCCESSORS AND ASSIGNS. This Agreement and the other Loan Documents shall be binding on and shall inure to the benefit of each Credit Party, Agent, Lenders and their respective successors and assigns (including, in the case of any Credit Party, a debtor-in-possession on behalf of such Credit Party), except as otherwise provided herein or therein. No Credit Party may assign, transfer, hypothecate or otherwise convey its rights, benefits, obligations or duties hereunder or under any of the other Loan Documents without the prior express written consent of Agent and Lenders. Any such purported assignment, transfer, hypothecation or other conveyance by any Credit Party without the prior express written consent of Agent and Lenders shall be void. The terms and provisions of this Agreement are for the purpose of defining the relative rights and obligations of each Credit Party, Agent and Lenders with respect to the transactions contemplated hereby and no Person shall be a third party beneficiary of any of the terms and provisions of this Agreement or any of the other Loan Documents. 11. MISCELLANEOUS 11.1 COMPLETE AGREEMENT; MODIFICATION OF AGREEMENT. The Loan Documents constitute the complete agreement between the parties with respect to the subject matter thereof and may not be modified, altered or amended except as set forth in SECTION 11.2. Any letter of interest, proposal letter, commitment letter, fee letter (other than the GE Capital Fee Letter) or confidentiality agreement between any Credit Party and Agent or any Lender or any of their respective Affiliates, predating this Agreement and relating to a financing of substantially similar form, purpose or effect shall be superseded by this Agreement. 73

11.2 AMENDMENTS AND WAIVERS. (a) Except for actions expressly permitted to be taken by Agent, no amendment, modification, termination or waiver of any provision of this Agreement or any other Loan Document, or any consent to any departure by any Credit Party therefrom, shall in any event be effective unless the same shall be in writing and signed by Agent and Borrower, and by Requisite Lenders, Supermajority Lenders or all affected Lenders, as applicable. Except as set forth in CLAUSES (b) AND (c) below, all such amendments, modifications, terminations or waivers requiring the consent of any Lenders shall require the written consent of Requisite Lenders. (b) No amendment, modification, termination or waiver of or consent with respect to any provision of this Agreement that increases the percentage advance rates set forth in the definition of the Borrowing Base, or that makes less restrictive the nondiscretionary criteria for exclusion from Eligible Accounts and Eligible Inventory set forth in SECTIONS 1.6 AND 1.7, shall be effective unless the same shall be in writing and signed by Agent, Supermajority Lenders and Borrower. (c) No amendment, modification, termination or waiver shall, unless in writing and signed by Agent and each Lender directly affected thereby: (i) increase the principal amount of any Lender's Commitment (which action shall be deemed only to affect those Lenders whose Commitments are increased and may be approved by Requisite Lenders, including those lenders whose Commitments are increased); (ii) reduce the principal of, rate of interest on or Fees payable with respect to any Loan or Letter of Credit Obligations of any affected Lender; (iii) extend any scheduled payment date (other than payment dates of mandatory prepayments under SECTION 1.3(b)(ii) AND (iii)) or final maturity date of the principal amount of any Loan of any affected Lender; (iv) waive, forgive, defer, extend or postpone any payment of interest or Fees as to any affected Lender; (v) release any Guaranty or, except as otherwise permitted herein or in the other Loan Documents, release, or permit any Credit Party to sell or otherwise dispose of, any Collateral with a value exceeding $20,000,000 in the aggregate (which action shall be deemed to directly affect all Lenders); (vi) change the percentage of the Commitments or of the aggregate unpaid principal amount of the Loans that shall be required for Lenders or any of them to take any action hereunder; and (vii) amend or waive this SECTION 11.2 or the definitions of the terms "Requisite Lenders" or "Supermajority Lenders" insofar as such definitions affect the substance of this SECTION 11.2. Furthermore, no amendment, modification, termination or waiver affecting the rights or duties of Agent or L/C Issuer under this Agreement or any other Loan Document shall be effective unless in writing and signed by Agent or L/C Issuer, as the case may be, in addition to Lenders required hereinabove to take such action. Each amendment, modification, termination or waiver shall be effective only in the specific instance and for the specific purpose for which it was given. No amendment, modification, termination or waiver shall be required for Agent to take additional Collateral pursuant to any Loan Document. No amendment, modification, termination or waiver of any provision of any Note shall be effective without the written concurrence of the holder of that Note. No notice to or demand on any Credit Party in any case shall entitle such Credit Party or any other Credit Party to any other or further notice or demand in similar or other circumstances. Any amendment, modification, termination, waiver or consent effected in accordance with this SECTION 11.2 shall be binding upon each holder of the Notes at the time outstanding and each future holder of the Notes. 74

(d) If, in connection with any proposed amendment, modification, waiver or termination (a "PROPOSED CHANGE"): (i) requiring the consent of all affected Lenders, the consent of Requisite Lenders is obtained, but the consent of other Lenders whose consent is required is not obtained (any such Lender whose consent is not obtained as described in this CLAUSE (i) and in CLAUSE L(ii) below being referred to as a "NON-CONSENTING LENDER"), or (ii) requiring the consent of Supermajority Lenders, the consent of Requisite Lenders is obtained, but the consent of Supermajority Lenders is not obtained, then, so long as Agent is not a Non-Consenting Lender, at Borrower's request Agent, or a Person reasonably acceptable to Agent, shall have the right with Agent's consent and in Agent's sole discretion (but shall have no obligation) to purchase from such Non-Consenting Lenders, and such Non-Consenting Lenders agree that they shall, upon Agent's request, sell and assign to Agent or such Person, all of the Commitments of such Non-Consenting Lenders for an amount equal to the principal balance of all Loans held by the Non-Consenting Lenders and all accrued interest and Fees with respect thereto through the date of sale, such purchase and sale to be consummated pursuant to an executed Assignment Agreement. (e) Upon payment in full in cash and performance of all of the Obligations (other than indemnification Obligations), termination of the Commitments and a release of all claims against Agent and Lenders, and so long as no suits, actions proceedings, or claims are pending or threatened against any Indemnified Person asserting any damages, losses or liabilities that are Indemnified Liabilities, Agent shall deliver to Borrower termination statements, mortgage releases and other documents necessary or appropriate to evidence the termination of the Liens securing payment of the Obligations. 11.3 FEES AND EXPENSES. Borrower shall reimburse (i) Agent for all fees, costs and expenses (including the reasonable fees and expenses of all of its counsel, advisors, consultants and auditors) and (ii) Agent (and, with respect to CLAUSES (c), (d) AND (e) below, all Lenders) for all fees, costs and expenses, including the reasonable fees, costs and expenses of counsel or other advisors (including environmental and management consultants and appraisers) incurred in connection with the negotiation and preparation of the Loan Documents and incurred in connection with: (a) the forwarding to Borrower or any other Person on behalf of Borrower by Agent of the proceeds of any Loan; (b) any amendment, modification or waiver of, or consent with respect to, or termination of, any of the Loan Documents or Related Transactions Documents or advice in connection with the syndication and administration of the Loans made pursuant hereto or its rights hereunder or thereunder; (c) any litigation, contest, dispute, suit, proceeding or action (whether instituted by Agent, any Lender, Borrower or any other Person and whether as a party, witness or 75

otherwise) in any way relating to the Collateral, any of the Loan Documents or any other agreement to be executed or delivered in connection herewith or therewith, including any litigation, contest, dispute, suit, case, proceeding or action, and any appeal or review thereof, in connection with a case commenced by or against any Credit Party or any other Person that may be obligated to Agent by virtue of the Loan Documents, including any such litigation, contest, dispute, suit, proceeding or action arising in connection with any work-out or restructuring of the Loans during the pendency of one or more Events of Default; PROVIDED that in the case of reimbursement of counsel for Lenders other than Agent, such reimbursement shall be limited to one counsel for all such Lenders; PROVIDED, further, that no Person shall be entitled to reimbursement under this clause (c) in respect of any litigation, contest, dispute, suit, proceeding or action to the extent any of the foregoing results from such Person's gross negligence or willful misconduct; (d) any attempt to enforce any remedies of Agent or any Lender against any or all of the Credit Parties or any other Person that may be obligated to Agent or any Lender by virtue of any of the Loan Documents, including any such attempt to enforce any such remedies in the course of any work- out or restructuring of the Loans during the pendency of one or more Events of Default; PROVIDED, that in the case of reimbursement of counsel for Lenders other than Agent, such reimbursement shall be limited to one counsel for all such Lenders; (e) any workout or restructuring of the Loans during the pendency of one or more Events of Default; and (f) efforts to (i) monitor the Loans or any of the other Obligations, (ii) evaluate, observe or assess any of the Credit Parties or their respective affairs, and (iii) verify, protect, evaluate, assess, appraise, collect, sell, liquidate or otherwise dispose of any of the Collateral; including, as to each of CLAUSES (a) THROUGH (f) above, all reasonable attorneys' and other professional and service providers' fees arising from such services and other advice, assistance or other representation, including those in connection with any appellate proceedings, and all expenses, costs, charges and other fees incurred by such counsel and others in connection with or relating to any of the events or actions described in this SECTION 11.3, all of which shall be payable, on demand, by Borrower to Agent. Without limiting the generality of the foregoing, such expenses, costs, charges and fees may include: fees, costs and expenses of accountants, environmental advisors, appraisers, investment bankers, management and other consultants and paralegals; court costs and expenses; photocopying and duplication expenses; court reporter fees, costs and expenses; long distance telephone charges; air express charges; telegram or telecopy charges; secretarial overtime charges; and expenses for travel, lodging and food paid or incurred in connection with the performance of such legal or other advisory services. Notwithstanding the foregoing provisions of this SECTION 11.3, absent a Default or Event of Default Borrower shall not be required to pay for (i) more than one inventory appraisal per year or (ii) more than two collateral audits per year. 11.4 NO WAIVER. Agent's or any Lender's failure, at any time or times, to require strict performance by the Credit Parties of any provision of this Agreement or any other Loan Document shall not 76

waive, affect or diminish any right of Agent or such Lender thereafter to demand strict compliance and performance herewith or therewith. Any suspension or waiver of an Event of Default shall not suspend, waive or affect any other Event of Default whether the same is prior or subsequent thereto and whether the same or of a different type. Subject to the provisions of SECTION 11.2, none of the undertakings, agreements, warranties, covenants and representations of any Credit Party contained in this Agreement or any of the other Loan Documents and no Default or Event of Default by any Credit Party shall be deemed to have been suspended or waived by Agent or any Lender, unless such waiver or suspension is by an instrument in writing signed by an officer of or other authorized employee of Agent and the applicable required Lenders and directed to Borrower specifying such suspension or waiver. 11.5 REMEDIES. Agent's and Lenders' rights and remedies under this Agreement shall be cumulative and nonexclusive of any other rights and remedies that Agent or any Lender may have under any other agreement, including the other Loan Documents, by operation of law or otherwise. Recourse to the Collateral shall not be required. 11.6 SEVERABILITY. Wherever possible, each provision of this Agreement and the other Loan Documents shall be interpreted in such a manner as to be effective and valid under applicable law, but if any provision of this Agreement or any other Loan Document shall be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement or such other Loan Document. 11.7 CONFLICT OF TERMS. Except as otherwise provided in this Agreement or any of the other Loan Documents by specific reference to the applicable provisions of this Agreement, if any provision contained in this Agreement conflicts with any provision in any of the other Loan Documents, the provision contained in this Agreement shall govern and control. 11.8 CONFIDENTIALITY. Agent and each Lender agree to use commercially reasonable efforts (equivalent to the efforts Agent or such Lender applies to maintain the confidentiality of its own confidential information) to maintain as confidential all confidential information provided to them by the Credit Parties and designated as confidential for a period of 2 years following receipt thereof, except that Agent and each Lender may disclose such information (a) to Persons employed or engaged by Agent or such Lender in evaluating, approving, structuring or administering the Loans and the Commitments; (b) to any bona fide assignee or participant or potential assignee or participant that has agreed to comply with the covenant contained in this SECTION 11.8 (and any such bona fide assignee or participant or potential assignee or participant may disclose such information to Persons employed or engaged by them as described in CLAUSE (a) ABOVE); (c) as 77

required or requested by any Governmental Authority or reasonably believed by Agent or such Lender to be compelled by any court decree, subpoena or legal or administrative order or process; (d) as, on the advise of Agent's or such Lender's counsel, is required by law; (e) in connection with the exercise of any right or remedy under the Loan Documents or in connection with any Litigation to which Agent or such Lender is a party; or (f) that ceases to be confidential through no fault of Agent or any Lender. 11.9 GOVERNING LAW.

(ii) As between Agent and any Lender and Borrower, Borrower assumes all risks of the acts and omissions of, or misuse of any Letter of Credit by beneficiaries of any Letter of Credit. In furtherance and not in limitation of the foregoing, to the fullest extent permitted by law neither Agent nor any Lender shall be responsible for: (A) the form, validity, sufficiency, accuracy, genuineness or legal effect of any document issued by any party in connection with the application for and issuance of any Letter of Credit, even if it should in fact prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent or forged; (B) the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign any Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, that may prove to be invalid or ineffective for any reason; (C) failure of the beneficiary of any Letter of Credit to comply fully with conditions required in order to demand payment under such Letter of Credit; PROVIDED, that in the case of any payment by Agent under any Letter of Credit or guaranty B-4

Borrower and its Subsidiaries on a consolidated basis shall not make Capital Expenditures during any Fiscal Year that exceed $25,000,000 in the aggregate; provided, however, that amounts permitted to be expended in any one Fiscal Year that are not expended during such Fiscal Year (not including any amount permitted to be carried forward from a prior Fiscal Year) shall be permitted to be expended in, but only in, the next subsequent Fiscal Year. (b) MINIMUM FIXED CHARGE COVERAGE RATIO. Holdings and its Subsidiaries shall have on a consolidated basis at the end of each Fiscal Quarter, a Fixed Charge Coverage Ratio for the 12-month period then ended of not less than 1.1 to 1.0. Unless otherwise specifically provided herein, any accounting term used in the Agreement shall have the meaning customarily given such term in accordance with GAAP, and all financial computations hereunder shall be computed in accordance with GAAP consistently applied. That certain items or computations are explicitly modified by the phrase "in accordance with GAAP" shall in no way be construed to limit the foregoing. If any "Accounting Changes" (as defined below) occur and such changes result in a change in the calculation of the financial covenants, standards or terms used in the Agreement or any other Loan Document, then Borrower, Agent and Lenders agree to enter into negotiations in order to amend such provisions of the Agreement so as to equitably reflect such Accounting Changes with the desired result that the criteria for evaluating Borrower's and its Subsidiaries' financial condition shall be the same after such Accounting Changes as if such Accounting Changes had not been made; PROVIDED, however, that the agreement of Requisite Lenders to any required amendments of such provisions shall be sufficient to bind all Lenders. "ACCOUNTING CHANGES" means (i) changes in accounting principles required by the promulgation of any rule, regulation, pronouncement or opinion by the Financial Accounting Standards Board of the American Institute of Certified Public Accountants (or successor thereto or any agency with similar functions), (ii) changes in accounting principles concurred in by Borrower's certified public accountants; (iii) purchase accounting adjustments under A.P.B. 16 or 17 and EITF 88-16, and the application of the accounting principles set forth in FASB 109, including the establishment of reserves pursuant thereto and any subsequent reversal (in whole or in part) of such reserves; and (iv) the reversal of any reserves established as a result of purchase accounting adjustments. If Agent, Borrower and Requisite Lenders agree upon the required amendments, then after appropriate amendments have been executed and the underlying Accounting Change with respect thereto has been implemented, any reference to GAAP contained in the Agreement or in any other Loan Document shall, only to the extent of G-1

such Accounting Change, refer to GAAP, consistently applied after giving effect to the implementation of such Accounting Change. If Agent, Borrower and Requisite Lenders cannot agree upon the required amendments within 30 days following the date of implementation of any Accounting Change, then all Financial Statements delivered and all calculations of financial covenants and other standards and terms in accordance with the Agreement and the other Loan Documents shall be prepared, delivered and made without regard to the underlying Accounting Change. For purposes of SECTION 8.1, a breach of a Financial Covenant contained in this ANNEX G shall be deemed to have occurred as of any date of determination by Agent or as of the last day of any specified measurement period, regardless of when the Financial Statements reflecting such breach are delivered to Agent.

RESPECTIVE INTERESTS IN RECEIVABLES ASSETS AND LENDERS COLLATERAL. (a) Except for all rights to access to and use of Records granted to the Receivables Agent, the Purchaser Agents and the Receivables Purchasers pursuant to the Receivables Documents and except for the Receivables Interest of the Receivables Agent (for the benefit of the Purchaser Agents and Receivables Purchasers) in Returned Goods, which interest is senior in all respects to any Lenders Interest therein, each of the Receivables Seller and the Receivables Agent (for itself and on behalf of each Receivables Purchaser) agrees that it does not have and shall not have any Receivables Interest in any of the Lenders Collateral. Each of the Receivables Seller and the Receivables Agent (for itself and on behalf of each Receivables Purchaser) agrees that it shall not request or accept, directly or indirectly (by assignment or otherwise) from WESCO or any other Originator any collateral security for payment of any Receivables Claims (other than any such collateral security included in the Receivables Assets and the right of access to and use of Records granted to the Receivables Agent and the Receivables Purchasers pursuant to the Receivables Documents) and hereby releases any Receivables Interest in any such collateral security. (b) Except for rights in Returned Goods granted to the Lenders Agent and the Lenders, which Lenders Interest is junior and subordinate to any Receivables Interest therein, the 7

Lenders Agent (for itself and on behalf of each Lender) agrees that neither the Lenders Agent nor the Lenders have, nor shall they have, any Lenders Interest in the Receivables Assets. 2.3. DISTRIBUTION OF PROCEEDS. At all times, all proceeds of Lenders Collateral and Receivables Assets shall be distributed in accordance with the following procedure: (a) All proceeds of the Lenders Collateral shall be paid to the Lenders Agent for application on the Lenders Claim and other obligations and liabilities owing under the Credit Agreement and other Loan Documents until the Lenders Claim and such other obligations and liabilities have been paid and satisfied in full in cash and each of the Credit Agreement and the other Loan Documents is terminated and, thereafter, any remaining proceeds shall be paid to WESCO or as otherwise required by applicable law. The Receivables Seller and the Receivables Agent (for itself and on behalf of each Receivables Purchaser) agrees that none of the Receivables Seller, the Receivables Agent or the Receivables Purchasers have, nor shall they have, any Receivables Interest in such remaining proceeds. The foregoing shall not, however, impair any claim or any right or remedy which the Receivables Seller, the Receivables Agent, the Purchaser Agents or the Receivables Purchasers may have against WESCO or any other Originator under the Receivables Documents or otherwise. (b) All proceeds of the Receivables Assets shall be paid to the Receivables Agent for application against the Receivables Claim and for application in accordance with the Receivables Documents until the Receivables Claim has been paid and satisfied in full in cash and the Receivables Documents have terminated and, thereafter, any remaining proceeds shall be paid to the Receivables Seller or as otherwise required by applicable law. The Lenders Agent (for itself and on behalf of the Lenders) agrees that neither the Lenders Agent nor the Lenders have, nor shall they have, any Lenders Interest in such remaining proceeds. The foregoing shall not, however, impair any claim or any right or remedy which the Lenders Agent or the Lenders may have against WESCO or any other Originator under the Loan Documents or otherwise. (c) In the event that any of the Receivables Seller, the Receivables Agent or the Receivables Purchasers now or hereafter obtains possession of any Lenders Collateral, it shall immediately deliver to the Lenders Agent such Lenders Collateral (and until delivered to the Lenders Agent such Lenders Collateral shall be held in trust for the Lenders Agent). Each of the Receivables Seller, the Receivables Agent (for itself and on behalf of each Receivables Purchaser) further agrees to immediately turn over the proceeds of any Disposition of Lenders Collateral which it (or any Receivables Purchaser) might receive while any Lenders Claim, any other obligations or liabilities under the Credit Agreement, any other Loan Document or any commitment to make financial accommodations thereunder remain outstanding, regardless of whether the Lenders Agent has a perfected and enforceable lien in the assets of WESCO or any other Originator from which the proceeds of any such Disposition have been received. (d) In the event that any of the Lenders or the Lenders Agent now or hereafter obtains possession of any Receivables Assets, it shall immediately deliver to the Receivables Agent such Receivables Assets (and until delivered to the Receivables Agent such Receivables Assets shall be held in trust for the Receivables Agent). The Lenders Agent (for itself and on behalf of each Lenders) further agrees to immediately turn over the proceeds of any Disposition 8

of Receivables Assets to the Receivables Agent which it (or the Lenders) might receive while any Receivables Claim, any other obligations or liabilities under the Receivables Documents or any commitment to make financial accommodations thereunder remain outstanding, regardless of whether the Receivables Agent has a perfected and enforceable lien in the assets from which the proceeds of such Disposition have been received. (e) To the extent that any Inventory of WESCO or any other Originator has been commingled with Returned Goods in which the Receivables Interest continues as provided in SECTION 2.1 above, and the Lenders Agent or any Lenders receives any proceeds on account of such Returned Goods (whether by reason of sale or by reason of insurance payments on account thereof) prior to release of such Receivables Interest, then all proceeds of such Returned Goods shall, promptly upon receipt of such proceeds by Lenders Agent, be paid to the Receivables Agent for application against the Receivables Claim. 2.4. UNSOLD RECEIVABLES. (a) The Receivables Seller and the Receivables Agent (for itself and on behalf of each Receivables Purchaser) hereby acknowledge that the Lenders Agent on behalf of the Lenders and itself shall be entitled to the Collections of Unsold Receivables. (b) Each of the parties hereto hereby agrees that all Collections received on account of Receivables Assets shall be paid or delivered to the Receivables Agent for application in accordance with SECTION 2.3(b) and all Collections received on account of Unsold Receivables shall be paid or delivered to the Lenders Agent for application in accordance with SECTION 2.3(a). (c) The Lenders Agent agrees that it shall not exercise any rights it may have under the Loan Documents to send any notices to Obligors informing them of the Lenders' interest (if any) in the Receivables or directing such Obligors to make payments in any particular manner of any amounts due under the Receivables prior to the payment in full of the Receivables Claim and the termination of the Receivables Documents, except that from and after any date on which (x) a Receivables Termination Notice has been delivered pursuant to Section 2.18, (y) the termination and cessation of transfers of Receivables is required to be effective under the terms of Section 2.18 and (z) the Receivables Claim has been paid in full or the Purchased Receivables giving rise to any unpaid Receivables Claim have been written off in accordance with their terms, the Lenders Agent may inform any Obligors of Unsold Receivables that such Unsold Receivables have been assigned to the Lenders Agent, so long as such notices do not under any circumstances direct that payments on account of such Unsold Receivables be made to any location or account to which payments on account of Purchased Receivables are required to be made pursuant to the terms of the Receivables Documents. 2.5. ENFORCEMENT ACTIONS. Each of the Lenders Agent and the Receivables Agent agrees to use reasonable efforts to give an Enforcement Notice to the others prior to commencement of Enforcement (but failure to do so shall not prevent such Person from commencing Enforcement or affect its rights hereunder nor create any cause of action or liability against such Person). Subject to the foregoing, each of the parties hereto agrees that during an Enforcement Period: 9

(a) Subject to any applicable restrictions in the Receivables Documents, the Receivables Agent may at its option and without the prior consent of the other parties hereto, take any action to (i) accelerate payment of the Receivables Claim or any other obligations and liabilities under any of the Receivables Documents and (ii) liquidate the Receivables Assets or to foreclose or realize upon or enforce any of its rights with respect to the Receivables Assets; PROVIDED, however, that, subject to Section 2.3(e), the Receivables Agent shall not take any action to foreclose or realize upon or to enforce any rights it may have with respect to any Receivables Assets constituting Returned Goods which have been commingled with the Lenders Collateral without the prior written consent of the Lenders Agent. (b) Subject to any applicable restrictions in the Loan Documents, the Lenders Agent or the Lenders may, at their option and without the prior consent of the other parties hereto, take any action to accelerate payment of the Lenders Claim or any other obligation or liability arising under the Credit Agreement or any of the other Loan Documents, foreclose or realize upon or enforce any of their rights with respect to the Lenders Collateral, including, except as otherwise provided in SECTION 2.3(e), with respect to any Receivables Assets constituting Returned Goods that have been commingled with the Lenders Collateral, or take any other actions as they deem appropriate; PROVIDED, HOWEVER, that the Lenders Agent shall not otherwise take any action to foreclose or realize upon or to enforce any rights it may have with respect to uncommingled Returned Goods without the Receivables Agent's prior written consent unless the Receivables Claim shall have been first paid and satisfied in full and the Receivables Documents have terminated. (c) If Returned Goods are commingled with Inventory, the parties agree to cooperate in the disposition of such Returned Goods and Inventory and the application of the proceeds thereof as provided in SECTION 2.3(e). 2.6. ACCESS TO RECORDS. Subject to any applicable restrictions in the Receivables Documents (but without limiting any rights under the Receivables Documents), each of the Receivables Purchasers, the Purchaser Agents and the Receivables Agent may enter one or more premises of WESCO, any other Originator, the Receivables Seller or their respective affiliates, whether leased or owned, at any time during reasonable business hours, without force or process of law and without obligation to pay rent or compensation to WESCO, any other Originator, the Receivables Seller, such affiliates, the Lenders or the Lenders Agent, whether before, during or after an Enforcement Period, and may have access to and use of all Records located thereon and may have access to and use of any other property to which such access and use are granted under the Receivables Documents. 2.7. ACCOUNTINGS. The Lenders Agent agrees to render statements to the Receivables Agent upon reasonable prior written request, which statements shall identify in reasonable detail the Unsold Receivables and shall render an account of the Lenders Claim, giving effect to the application of proceeds of Lenders Collateral as hereinbefore provided. The Receivables Agent agrees to render Purchase Reports (as defined in the Receivables Purchase 10

Agreement) to the Lenders Agent upon reasonable prior written request.

INDEPENDENT CREDIT INVESTIGATIONS. Neither the Receivables Purchasers, the Receivables Agent, the Lenders Agent nor the Lenders nor any of their respective directors, officers, agents or employees shall be responsible to the other or to any other person, firm, corporation or entity for the solvency, financial condition or ability of WESCO, any other Originator or the Receivables Seller to repay the Receivables Claim or the Lenders Claim, or for the worth of the Receivables Assets or the Lenders Collateral, or for statements of WESCO, any other Originator, the Receivables Seller or the Credit Parties, oral or written, or for the validity, sufficiency or enforceability of the Receivables Claim, the Lenders Claim, the Receivables Documents, the Loan Documents, the Receivables Agent's interest in the Receivables Assets or the Lenders' or Lenders Agent's interest in the Lenders Collateral.

reasonable efforts to give, concurrently with any written amendment, waiver or other modification in the Receivables Documents with respect to the Receivable Assets or the Collateral, prompt notice to the Lenders Agent of the same; PROVIDED, however, that the failure to do so shall not create a cause of action against any party failing to give such notice or create any claim or right on behalf of any third party or affect any such amendment or modification. Each party hereto shall, upon reasonable request of any other party hereto, provide copies of all such modifications or amendments and copies of all other agreements, instruments, filings or documentation relevant to the Receivables Assets or the Lenders Collateral.

Each of WESCO and the other Obligors acknowledges that the provisions of this Agreement shall not give it or any other Credit Party any substantive rights as against the Lenders Agent or the Lenders and that nothing in this Agreement shall (except as expressly provided herein) amend, modify, change or supersede the terms of the Loan Documents as between WESCO, the other Credit Parties, the Lenders Agent and the Lenders.

The Receivable Agent agrees, upon the written request of the Lenders Agent (an "Initial Notification Request"), to provide a written response stating whether or not the Receivables Documents have been terminated and all monetary obligations under the Receivables Documents have been satisfied in full and, if such termination and satisfaction have occurred, to notify the applicable banks under the Blocked Account Agreements (it being understood that the Lenders Agent shall deliver an Initial Notification Request only if it believes in good faith that the Receivables Documents may have been terminated and all monetary obligations thereunder may have been paid, or if the Lenders Agent has been instructed in good faith by the Requisite Lenders to make such Initial Notification Request).

In the event that the Receivables Agent has not responded in writing within three (3) Business Days of its receipt of the Final Notification Request, the Lenders Agent shall be entitled to activate the Blocked Account Agreements. Notwithstanding anything to the contrary in this Section 2.19, if the Receivables Agent responds in writing to an Initial Notification Request or a Final 14

Notification Request within the respective time periods allowed herein for such response, and such written response states that the Receivables Documents have not terminated or that all monetary obligations in respect thereof have not been satisfied, the Lenders Agent (regardless of whether it disputes the statements set forth in such response) shall not be entitled to activate any of the Blocked Accounts (or otherwise notify the applicable account banks to take other actions with respect to such Blocked Accounts) unless and until the Receivables Agent shall have indicated in writing (or a court of competent jurisdiction shall have determined) that the Receivables Documents have been terminated and all monetary obligations in respect thereof have been satisfied. 2.20 NO PETITION. The Lenders Agent, on behalf of itself and the Lenders, agrees that it shall not institute against or join any other Person in instituting against the Receivables Seller or a Receivables Purchaser any bankruptcy, reorganization, insolvency or liquidation proceeding, or other proceeding under any federal or state bankruptcy, insolvency or similar law until after the payment in full of the Receivable Claims and termination of the Receivable Documents.
