WESCO INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited) 1. ORGANIZATION WESCO International, Inc. and its subsidiaries (collectively, "WESCO"), headquartered in Pittsburgh, Pennsylvania, is a full-line distributor of electrical supplies and equipment and is a provider of integrated supply procurement services. WESCO currently operates approximately 350 branch locations and five distribution centers in the United States, Canada, Mexico, Puerto Rico, Guam, the United Kingdom, Nigeria and Singapore. 2. ACCOUNTING POLICIES Basis of Presentation The unaudited condensed consolidated financial statements include the accounts of WESCO and all of its subsidiaries and have been prepared in accordance with Rule 10-01 of the Securities and Exchange Commission. The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in WESCO's 2003 Annual Report on Form 10-K filed with the Securities and Exchange Commission. The unaudited condensed consolidated balance sheet as of September 30, 2004, the unaudited condensed consolidated statements of income for the three months and nine months ended September 30, 2004 and September 30, 2003, respectively and the unaudited condensed consolidated statements of cash flows for the nine months ended September 30, 2004, and September 30, 2003, respectively, in the opinion of management, have been prepared on the same basis as the audited consolidated financial statements and include all adjustments necessary for the fair presentation of the results of the interim periods. All adjustments reflected in the unaudited condensed consolidated financial statements are of a normal recurring nature unless indicated. Results for the interim periods presented are not necessarily indicative of the results to be expected for the full year. Stock Options During the year ended December 31, 2003, WESCO adopted the measurement provisions of Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting for Stock-Based Compensation". This change in accounting method was applied on a prospective basis in accordance with SFAS No. 148, "Accounting for Stock-Based Compensation - Transition and Disclosure - an amendment of SFAS No. 123." Stock options awarded prior to 2003 are accounted for under the intrinsic value method under Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees." The Company recognized $0.6 million and $1.3 million of compensation expense for the three months and nine months ended September 30, 2004, respectively. The Company recognized $0.2 million during the three months and nine months ended September 30, 2003. The following table presents the pro forma results as if the fair-value based method of accounting for stock-based awards had been applied to all outstanding options: 5

Recent Accounting Pronouncements In January 2003, the FASB issued Interpretation No. 46 (revised December 2003), "Consolidation of Variable Interest Entities." This interpretation requires unconsolidated variable interest entities to be consolidated by their primary beneficiaries if the entities do not effectively disperse the risk and rewards of ownership among their owners and other parties involved. This interpretation, as amended, is effective for all entities subject to this interpretation no later than the end of the first period that ends after March 15, 2004. The adoption of this interpretation did not have an impact on the Company's consolidated financial statements. In September 2004, the FASB issued EITF 04-10 "Applying Paragraph 19 of FASB Statement No. 131, Disclosures about Segments of an Enterprise and Related Information, in Determining Whether to Aggregate Operating Segments That Do Not Meet the Quantitative Thresholds," Issue Summary No. 1. ("EITF 04-10"). EITF 04-10 establishes evaluation criteria for an enterprise to use when determining whether operating segments that do not meet the quantitative thresholds can still be aggregated in accordance with paragraph 19 of SFAS No. 131, "Disclosure about Segments of an Enterprise and Related Information." ("FAS 131"). We have evaluated EITF 04-10 and have determined that it has no impact on our financial statements. 3. EARNINGS PER SHARE The following table sets forth the details of basic and diluted earnings per share: THREE MONTHS ENDED SEPTEMBER 30 Dollars in thousands, except per share amounts 2004 2003 - -------------------------------------------------------- ----------- ----------- Reported net income .................................... $ 19,037 $ 8,373 =========== =========== Weighted average common shares outstanding used in computing basic earnings per share ................. 41,851,989 45,129,308 Common shares issuable upon exercise of dilutive stock options ...................................... 2,383,600 1,790,875 ----------- ----------- Weighted average common shares outstanding and common share equivalents used in computing diluted earnings per share .......................................... 44,235,589 46,920,183 =========== =========== Earnings per share: Basic .............................................. $ 0.45 $ 0.19 Diluted ............................................ $ 0.43 $ 0.18 ----------- ----------- 6

Options to purchase 5.8 million shares of common stock at a weighted average exercise price of $9.23 per share were outstanding as of September 30, 2003 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.

ACCOUNTS RECEIVABLE SECURITIZATION WESCO maintains an accounts receivable securitization program ("Receivables Facility") that was amended and increased to $325 million in August, 2004. The facility provides for a $190 million purchase commitment with a term of 364 days and a $135 million purchase commitment with a term of three years. 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 September 30, 2004 and December 31, 2003, securitized accounts receivable totaled approximately $427 million and $330 million, respectively, of which the subordinated retained interest was approximately $127 million and $105 million, respectively. Accordingly, approximately $300 million and $225 million of accounts receivable balances were removed from the consolidated balance sheets at September 30, 2004 and December 31, 2003, respectively. Costs associated with the Receivables Facility totaled $1.9 million for the three months ended September 30, 2004 and $ 0.7 million for the three months ended September 30, 2003. Costs associated with the Receivables Facility totaled $4.4 million and $3.4 million for the nine-months ended September 30, 2004 and 2003, respectively. These amounts are recorded as other expenses in the consolidated statements of income 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 2004 were a discount rate of 2% and an estimated life of 1.5 months. At September 30, 2004, 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. 7

ACQUISITIONS In 1998, WESCO acquired substantially all the assets and assumed substantially all liabilities and obligations relating to the operations of Bruckner Supply Company, Inc. ("Bruckner"). The terms of the purchase agreement provide for additional contingent consideration to be paid based on achieving certain earnings targets. The amount of earn-out proceeds payable in any single year subsequent to achieving the earnings target is capped under this agreement at $30 million per year. As a result of Bruckner's performance in 2003, WESCO recorded a liability of $80 million as of December 31, 2003 for contingent consideration relating to the Bruckner agreement. During the first nine months of 2004 WESCO paid $30 million pursuant to this agreement. In June 2004, the remaining $50 million due under the agreement was converted into a note payable ($30 million, due in June 2005, classified as current and $20 million, due in June 2006, classified as long-term debt) and pays interest at 10%. No additional amounts can be earned under this agreement. Certain other acquisitions also contain contingent consideration provisions, only one of which could require a significant payment. Management estimates this payment could range up to $20 million and would be made in multiple payments between 2004 and 2008. Under this provision, a payment of $3.1 million is due in the fourth quarter of 2004. 7.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion should be read in conjunction with the information in the unaudited condensed consolidated financial statements and notes thereto included herein and WESCO International Inc.'s Financial Statements and Management's Discussion and Analysis of Financial Condition and Results of Operations included in its 2003 Annual Report on Form 10-K. GENERAL WESCO is a full-line distributor of electrical supplies and equipment and is a provider of integrated supply procurement services. We currently operate approximately 350 branch locations and five distribution centers in the United States, Canada, Mexico, Puerto Rico, Guam, the United Kingdom, Nigeria and Singapore. 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. Approximately 87% of our net sales are generated from operations in the U.S., 10% from Canada and the remainder from other countries. Sales growth, along with positive impact from our margin and cost improvement initiatives contributed to improved financial results for the first nine months of 2004. Sales increased 13.0% over the same period last year and our gross margin percentage was 19.1% for the current year. Operating income increased by 79.3% compared with last year's comparable period and the year to date net income was $47.8 million versus $20.6 million in last year's comparable period. As a result, our diluted earnings per share were $1.10 for the nine-month period, a 150% improvement over earnings per share during the same period last year. CASH FLOW We generated $92.3 million in operating cash flow during the first nine months of 2004. Included in this amount was a $75.0 million cash inflow from an increase in our Receivables Facility. During the nine-month period ended September 30, 2004, we repurchased $45.3 million in aggregate principal amount of senior subordinated notes at a net loss of $2.1 million, paid $30 million pursuant to the terms of the Bruckner purchase agreement and made a payment of $20.1 million to certain employees for the net equity value of stock options originally granted in 1994 and 1995. FINANCING AVAILABILITY As of September 30, 2004, we had approximately $175 million in available borrowing capacity under our financing facilities. OUTLOOK Improvements in operations and our capital structure made in 2003 have positioned us well for the remainder of 2004. Though we continue to see favorable macroeconomic data that reflects activity levels in our major end markets, capital spending in the manufacturing and construction markets we serve still remains well below the higher levels experienced in 1999 and 2000. Even with further improvement, we anticipate a lag before we see a broad based increase in capital spending. Accordingly, we continue to focus on selling and marketing initiatives to increase market share, enhance margin expansion programs and focus on cost containment as we drive to improve our operating performance for the rest of 2004. CRITICAL ACCOUNTING POLICIES AND ESTIMATES During the nine-month period ended 2004, there were no significant changes to WESCO's Critical Accounting Policies and Estimates referenced in the 2003 Annual Report on Form 10-K. RESULTS OF OPERATIONS Third Quarter of 2004 versus Third Quarter of 2003 The following table sets forth the percentage relationship to net sales of certain items in WESCO's unaudited condensed consolidated statements of income for the periods presented: 16

THREE MONTHS ENDED SEPTEMBER 30 ------------------------------- 2004 2003 ---- ---- Net sales 100.0% 100.0% Gross profit 18.7 18.6 Selling, general and administrative expenses 14.1 15.1 Depreciation and amortization 0.4 0.6 ----- ----- Income from operations 4.2 2.9 Interest expense 1.0 1.3 Loss on debt extinguishments 0.1 0.1 Other expense 0.2 0.1 ----- ----- Income before income taxes 2.9 1.4 Provision for income taxes 0.9 0.4 ----- ----- Net income 2.0% 1.0% ===== ===== Net sales in the third quarter of 2004 totaled $974.5 million versus $825.6 million in the comparable 2003 quarter, an 18.0% increase. Approximately 15% of the increase in sales was attributable to stronger demand resulting from favorable economic activity and market share gain. The remaining increase was due to improved pricing on commodity products, approximately 2%, and the strength of the Canadian dollar. Gross profit for the third quarter of 2004 totaled $182.6 million and was up compared to 2003's third quarter, as the gross margin percentage increased to 18.7% versus 18.6% last year. The slight improvement in gross margin percentage was the result of improved performance with supplier volume rebate and cash discount programs offset somewhat by sales mix differences. Selling, general and administrative ("SG&A") expenses in the third quarter of 2004 totaled $137.2 million versus $124.7 million in last year's comparable quarter. Total payroll expense increased approximately $11.0 million over last year's third quarter principally from increased variable incentive compensation costs of $7.1 million, increased health care and benefits costs of $1.3 million and stock options of $0.3 million associated with the adoption of SFAS No. 123 in 2003. Shipping and handling expense included in SG&A was $9.5 million in the third quarter of 2004 compared with $9.3 million in last year's third quarter. As a percentage of net sales, SG&A expenses decreased to 14.1% from 15.1% in the prior year quarter reflecting LEAN initiatives and the leverage of higher sales volume. Depreciation and amortization was $4.4 million in the third quarter of 2004 versus $5.1 million in last year's third quarter. The decline in depreciation and amortization was primarily due to less depreciation expense on computer hardware and less software amortization as the applicable assets became fully depreciated. Interest expense totaled $10.3 million for the third quarter of 2004 versus $10.8 million in last year's comparable quarter. The decline was due to a lower amount of indebtedness outstanding during the current quarter as compared to the third quarter of 2003 offset somewhat by slightly higher effective interest rates. Loss on debt extinguishments of $0.4 million for the third quarter of 2004 represented the loss on the repurchase of our senior subordinated notes versus a loss on debt extinguishments of $0.5 million during last year's comparable period. Other expense during the third quarter of 2004 totaled $1.9 million compared with $0.7 million in the third quarter of 2003, reflecting a higher receivable level in 2004 leading to more costs associated with the Receivables Facility. Income tax expense totaled $9.2 million in the third quarter of 2004 and the effective tax rate was a 32.5%. Income tax expense totaled $3.4 million in the third quarter of 2003 and the effective tax rate was a 28.9%. We recapitalized our Canadian operations to reflect the proportionate debt structure of the Canadian and US operations and to improve efficiency in cash flow movement of funds for business and tax purposes. As a result of this recapitalization, the effective tax rate was reduced by 2.4% during the third quarter of 2004. Last year's effective tax rate differed from the statutory rate primarily as a result of the recognition of certain foreign tax credits that became available in last year's third quarter. For the third quarter of 2004, net income totaled $19.0 million, or $0.43 per diluted share, compared with $8.4 million, or $0.18 per diluted share, in the third quarter of 2003. The improvements in net income and earnings per share were primarily attributable to increased sales and gross profit offset somewhat by the increase in payroll expense and an increase in the effective tax rate. 17

Nine Months Ended September 30, 2004 versus Nine Months Ended September 30, 2003 The following table sets forth the percentage relationship to net sales of certain items in WESCO's unaudited condensed consolidated statements of income for the periods presented: NINE MONTHS ENDED SEPTEMBER 30 2004 2003 ----- ----- Net sales 100.0% 100.0% Gross profit 19.1 18.5 Selling, general and administrative expenses 14.6 15.3 Depreciation and amortization 0.5 0.7 ----- ----- Income from operations 4.0 2.5 Interest expense 1.1 1.3 Loss on debt extinguishment - - Other expense 0.2 0.1 ----- ----- Income before income taxes 2.7 1.1 Provision for income taxes 0.9 0.2 ----- ----- Net income 1.8% 0.9% ----- ----- Net sales in the nine months ended September 30, 2004 totaled $2,753.3 million versus $2,436.6 million in the comparable 2003 period, a 13.0% increase. Approximately 10% of the increase in sales was attributable to stronger demand resulting from expanding economic activity. The remaining increase was split between improved pricing on commodity products of approximately 2% and the strength of the Canadian dollar of 1%. Gross profit for the nine months ended September 30, 2004 of $527.1 million was up versus last year's comparable period, as the gross margin percentage improved to 19.1% versus 18.5% last year. The increase in gross margin percentage was favorably impacted by approximately 45 basis points from improved performance with supplier volume rebate and cash discount programs, along with the positive effect of approximately 40 basis points due to the pass through of rising commodity prices. SG&A expenses during the nine months ended September 30, 2004 totaled $403.0 million versus $373.2 million in last year's comparable period. Total payroll expense increased approximately $26.9 million over last year's comparable period principally from increased variable incentive compensation costs of $15.8 million, increased health care and benefits costs of $4.5 million and stock options of $1.0 million associated with the adoption of SFAS No. 123 in 2003. Shipping and handling expense included in SG&A was $27.3 million versus $27.1 during last year's comparable period. As a percentage of net sales, SG&A expenses decreased to 14.6% compared with 15.3% in last year's nine-month period reflecting LEAN initiatives and the leverage of higher sales volume. Depreciation and amortization was $14.1 million in the first nine months of 2004 versus $15.4 million in last year's comparable period. The decline in depreciation and amortization was primarily due to less depreciation expense on computer hardware and less software amortization as the applicable assets became fully depreciated. Interest expense totaled $30.3 million for the nine months ended September 30, 2004 versus $32.1 million in last year's comparable period, a decrease of 5.5%. The decline was due to a lower amount of indebtedness outstanding during the current period. Loss on debt extinguishments of $2.1 million for the nine months ended September 30, 2004 represented the loss on the repurchase of our senior subordinated notes compared with a loss on debt extinguishments of $0.2 million last year. Other expense totaled $4.4 million in 2004, an increase from $3.4 million in the comparable 2003 period, principally reflecting costs associated with the accounts receivable securitization program. For the nine months ended September 30, 2004, income tax expense totaled $25.4 million and the effective tax rate was 34.7%. Income tax expense totaled $5.1 million in last year's comparable period and the effective tax rate was 20.0%. We recapitalized our Canadian operations to reflect the proportionate debt structure of the Canadian and US operations and to improve efficiency in cash flow movement of funds for business and tax purposes. As a result of this recapitalization, the effective tax rate was reduced by 1.3% during the nine months ended September 30, 2004. 18

The effective tax rate in the prior-year period differs from the statutory rate primarily as a result of the recognition of a $2.6 million benefit associated with the favorable resolution of certain prior year tax contingencies, combined with the recognition of a $0.6 million benefit associated with the utilization of a net operating loss. In addition, foreign tax credits contributed to the reduction in the effective rate during 2003. For the nine months ended September 30, 2004, net income totaled $47.8 million, or $1.10 per diluted share, versus $20.6 million, or $0.44 per diluted share, in last year's comparable period. The improvements in net income and earnings per share were primarily attributable to increased sales and gross profit offset somewhat by the increase in payroll expense and an increase in the effective tax rate. LIQUIDITY AND CAPITAL RESOURCES Total assets were $1.2 billion at September 30, 2004 and December 31, 2003, respectively. During the first nine months of 2004, total liabilities increased to $1.0 billion from $993.5 million at December 31, 2003. An increase in accounts payable of $88.3 million as a result of increased purchase activity was offset by $45 million in repurchases of senior subordinated notes, a $30 million payment made pursuant to earn-out provisions of the Bruckner acquisition agreement. During the first nine months of 2004, stockholders' equity increased $60.5 million to $228.2 million at September 30, 2004 principally as a result of $47.8 million of net income and increases in common stock and additional capital due to equity activity of $11.6 million. Our 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 these agreements relates to the acquisition of Bruckner, the terms of which provide for additional contingent consideration to be paid based on achieving earnings targets of earnings before interest, taxes, depreciation and amortization of Bruckner. The amount of earn-out proceeds earned that is payable in any single year subsequent to achieving the earnings target is capped under this agreement at $30 million per year. During the first nine months of 2004, WESCO paid $30 million pursuant to this agreement. The remaining $50 million due under the agreement was converted into a note payable ($30 million, due in June 2005, classified as current and $20 million, due in June 2006, classified as long-term debt) and pays interest at 10%. No additional amounts can be earned under this agreement. Certain other acquisitions also contain contingent consideration provisions, only one of which could require a significant payment. Management estimates this payment could be up to $20 million and would be made in multiple payments between 2004 and 2008. Under this provision, a payment of $3.1 million is due in the fourth quarter. To meet our funding requirements, we use a mix of internally generated cash flow, our revolving credit facility and our Receivables Facility. During October 2004, we filed a universal shelf registration statement with the SEC for a public offering of debt and equity securities of WESCO International and our wholly owned subsidiary, WESCO Distribution. The purpose of the offering is to raise funds for general corporate purposes, including but not limited to, reduction of our indebtedness. We finance our operating and investing needs, as follows: Mortgage Financing Facility In February 2003, we finalized a mortgage financing facility of $51 million. Total borrowings under the mortgage financing are subject to a 22-year amortization schedule with a balloon payment due at the end of the 10-year term. Proceeds from the borrowings were used primarily to reduce outstanding borrowings under the 2002 Revolving Credit Facility. 2002 Revolving Credit Facility 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 Canada. During 2003, we executed an amendment reducing the size of this revolving credit facility to $200 million. Availability under the facility, which matures in 2007, is limited to the amount of U.S. and Canadian eligible inventory and Canadian receivables applied against certain advance rates. Borrowings under the facility were used 19

to retire a previous revolving credit facility. Interest on this facility is at LIBOR plus a margin that ranges 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 we 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 our 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 excess availability under the agreement is less than $50 million, then we must maintain a fixed charge coverage ratio of 1.1 to 1.0. At September 30, 2004, the interest rate was 3.6%. As of September 30, 2004, we had no borrowings outstanding under this facility and approximately $175 million in availability, and consequently, we were not subject to any covenants in the agreement. Senior Notes As of September 30, 2004, we had $333.5 million in aggregate principal amount of 9.125% senior subordinated notes due 2008. The notes were issued with an average issue price of 98%. During the first nine months of 2004, we repurchased $45.3 million in aggregate principal amount of senior subordinated notes at a net loss of $2.1 million. Interest Rate Swap Agreements In September 2003, we entered into a $50 million interest rate swap agreement, and in December 2003, we entered into two additional $25 million interest rate swap agreements. These agreements have terms expiring concurrently with the maturity of our 9.125% senior subordinated notes and were entered into with the intent of converting $100 million of the senior subordinated notes from a fixed-to-floating rate. Pursuant to these agreements, we receive semi-annual fixed interest payments at the rate of 9.125% commencing December 1, 2003 and make semi-annual variable interest rate payments at six-month LIBOR rates plus a premium in arrears. The LIBOR rates in the agreements reset every six months and at September 30, 2004, the rates ranged from 6.50% to 6.72%. The agreements can be terminated by the counterparty in accordance with a redemption schedule that is consistent with the redemption schedule for the senior subordinated notes. We enter into interest rate swap agreements as a means to hedge our 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 our Consolidated Balance Sheets. Net amounts to be received or paid under the swap agreements are reflected as adjustments to interest expense. Off-Balance Sheet Arrangements-Accounts Receivable Securitization Program In September 2003, we entered into a $300 million Receivables Facility agreement with four financial institutions. The facility was amended and increased to $325 million in August 2004. The current facility provides for a $190 million purchase commitment with a term of 364 days, expiring August 30, 2005, and a $135 million purchase commitment with a term of three years or August 27, 2007. Presently, we expect the $190 million portion of the facility to be renewed in August 2005. 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 September 30, 2004, $300 million in funding was outstanding under the Receivables Facility. Cash Flow Operating Activities. Cash provided by operating activities for the first nine months of 2004 totaled $92.3 million compared to cash used by operating activities of $1.5 million in the prior year. Cash provided by operating activities in 2004 included cash inflows of $75.0 million associated with increases in eligible receivables related to our Receivables Facility. In 2003, cash used by operating activities included a cash outflow of $88.0 million due to decreases in eligible receivables related to our Receivables Facility. In 2004, cash generated by net income plus other adjustments totaling $67.6 million, along with cash inflows from increases in accounts payable of $87.3 million and prepaid expenses and other current assets of $12.5 million were partially offset by a $105.8 million use of cash for increased accounts receivable and a $60.2 million use of cash for increased inventory. The increases in 20

accounts payable, accounts receivable and inventory result primarily from the increase in business activity during the first nine months. The change in accounts receivable also includes the impact of a change in cash collection procedures. In 2003, cash generated by net income plus other adjustments totaling $37.3 million and cash generated by increases in accounts payable and other current and non-current liabilities totaling $45.8 million along with increased cash inflow from reductions of inventory of $19.7 million was partially offset by cash used to fund increases in accounts receivable totaling $19.8 million. Investing Activities. Net cash used in investing activities was $38.0 million rose during the first nine months of 2004, primarily due to a $30 million payment pursuant to the Bruckner purchase agreement and capital expenditures of $6.9 million. In 2003, net cash used in investing activities of $6.4 million included capital expenditures of $5.6 million along with acquisition payments totaling $2.0 million and were partially offset by proceeds received from the sale of property and buildings totaling $1.2 million. Financing Activities. Net cash used by financing activities during the first nine months of 2004 totaled $62.7 million primarily as a result of net debt repayments of $48.6 million and $20.1 million in cash payments made to certain employees for the redemption of stock options and were offset by $6.0 million in amounts received from the exercise of stock options. In 2003, net cash provided by financing activities totaled $15.1 million primarily as a result of completing the mortgage financing facility that provided $38 million partially offset by debt repayments. Contractual Cash Obligations and Other Commercial Commitments There have not been any material changes in our contractual obligations and other commercial commitments that would require an update to the disclosure provided in our Form 10-K for the year-ended December 31, 2003. 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. Overall, price changes from suppliers have historically been consistent with inflation and have not had a material impact on the Company's results of operations. However, as discussed in the results of operation, we did experience a significant rise in the price of certain commodity products. We were able to pass through a majority of the increase to customers in the first nine months of 2004. 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 Adopted Accounting Standards In January 2003, the FASB issued Interpretation No. 46 (revised December 2003), "Consolidation of Variable Interest Entities." This interpretation requires unconsolidated variable interest entities to be consolidated by their primary beneficiaries if the entities do not effectively disperse the risk and rewards of ownership among their owners and other parties involved. This interpretation, as amended, is effective for all entities subject to this interpretation no later than the end of the first period that ends after March 15, 2004. The adoption of this interpretation did not have an impact on our consolidated financial statements. In September 2004, the FASB issued EITF 04-10 "Applying Paragraph 19 of FASB Statement No. 131, Disclosures about Segments of an Enterprise and Related Information, in Determining Whether to Aggregate Operating Segments That Do Not Meet the Quantitative Thresholds," Issue Summary No. 1. ("EITF 04-10"). EITF 04-10 establishes evaluation criteria for an enterprise to use when determining whether operating segments that do not meet the quantitative thresholds can still be aggregated in accordance with paragraph 19 of SFAS No. 131, "Disclosure about Segments of an Enterprise and Related Information." ("FAS 131"). We have evaluated EITF 04-10 and have determined that it has no impact on our financial statements. 21

FORWARD-LOOKING STATEMENTS From time to time in this report and in other written reports and oral statements, references are made to expectations regarding the future performance of WESCO. When used in this context, the words "anticipates," "plans," "believes," "estimates," "intends," "expects," "projects" and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such words. Such statements including, but not limited to, WESCO's statements regarding its business strategy, growth strategy, productivity and profitability enhancement, new product and service introductions and liquidity and capital resources are based on management's beliefs, as well as on assumptions made by, and information currently available to, management, and involve various risks and uncertainties, certain of which are beyond WESCO's control. WESCO's actual results could differ materially from those expressed in any forward-looking statement made by or on behalf of WESCO. In light of these risks and uncertainties there can be no assurance that the forward-looking information will in fact prove to be accurate. Factors that might cause actual results to differ from such forward-looking statements include, but are not limited to, an increase in competition, the amount of outstanding indebtedness, the availability of appropriate acquisition opportunities, availability of key products, functionality of information systems, international operating environments and other risks that are described in WESCO's Annual Report on Form 10-K for the year ended December 31, 2003 which are incorporated by reference herein. WESCO has undertaken no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS Except as discussed below there have not been any material changes to WESCO's exposures to market risk during the nine months ended September 30, 2004 that would require an update to the disclosures provided in WESCO's Form 10-K for the year-ended December 31, 2003. As interest rates rose during the first half of 2004, the value of one of our interest rate swap agreements increased and as such, the counterparty required us to provide additional collateral. We deposited cash totaling approximately $0.5 million in an interest bearing account to satisfy the collateral requirements. ITEM 4. CONTROLS AND PROCEDURES An evaluation was performed under the supervision and with the participation of our management, including the Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO"), of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this quarterly report. Based on that evaluation, management, including the CEO and CFO, concluded that our disclosure controls and procedures were effective to ensure that information required to be disclosed by WESCO in reports that it files under the Exchange Act are recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission rules and forms. There have been no significant changes in internal control over financial reporting that occurred during the third fiscal quarter, that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting. 22

EXHIBIT 10.1 EMPLOYMENT AGREEMENT JULY 14, 2004 The parties to this Employment Agreement (this "Agreement") are Wesco International, Inc., a Delaware corporation (the "Company"), and John Engel (the "Executive"). The parties wish to provide for the employment of the Executive as Senior Vice President and Chief Operating Officer of the Company as of the date first above written (the "Effective Date"). Accordingly, the parties, intending to be legally bound, agree as follows: 1. Position and Duties. 1.1. Titles; Reporting; Duties. During the Employment Term (as defined in Section 2), the Company shall employ the Executive and the Executive shall serve the Company as its Senior Vice President and Chief Operating Officer on an at-will basis. As Senior Vice President and Chief Operating Officer of the Company, the Executive shall report to and otherwise shall be subject to the direction and control of the Chief Executive Officer of the Company and shall have such duties, responsibilities and authorities consistent with such position as may be assigned to him by the Chief Executive Officer from time to time. The Executive shall use his best efforts to promote the Company's interests and he shall perform his duties and responsibilities faithfully, diligently and to the best of his ability, consistent with sound business practices. The Executive may be required by the Chief Executive Officer to provide services to, or otherwise serve as an officer or director of, any direct or indirect subsidiary of the Company. The Executive shall comply with the Company's policies applicable to executive officers of the Company. 1.2. Outside Activities. The Executive shall devote substantially all of his full working time to the business and affairs of the Company. Notwithstanding the preceding sentence, the Executive may, with the prior approval of the Chief Executive Officer, engage in such other business and charitable activities that do not violate Section 8, create a conflict of interest or the appearance of a conflict of interest with the Company or materially interfere with the performance of his obligations to the Company under this Agreement. 1.3. Place of Employment. The Executive shall perform his duties under this Agreement at the Company's principal executive offices in Pittsburgh, Pennsylvania with the likelihood of substantial business travel. The Executive shall relocate his primary residence to Pittsburgh, Pennsylvania as soon as practicable after the Effective Date. The Company shall pay or reimburse the Executive's moving costs and related expenses in accordance with the Company's policy. During the period prior to such relocation, the Company shall pay or reimburse the Executive for his temporary housing

costs in Pittsburgh; provided, however, that such temporary housing arrangements shall be subject to pre-approval by the Company. 2. Term of Employment. The term of the Executive's employment by the Company under this Agreement shall be for a period of two (2) years commencing on the Effective Date (the "Employment Term"). The Employment Term shall be subject to earlier termination under Section 5 or Section 6 or extension as described in the next sentence. The Employment Term shall be extended automatically for an additional year as of the first anniversary of the Effective Date and as of each subsequent annual anniversary of the Effective Date (each such anniversary is referred to herein as an "Anniversary Date") unless at least ninety (90) days prior to any such Anniversary Date either party shall have given notice to the other party that the Employment Term shall not be so extended. 3. Compensation. 3.1. Base Salary. During the Employment Term, the Executive shall be entitled to receive a base salary ("Base Salary") at the annual rate of $450,000 for services rendered to the Company or any of its direct or indirect subsidiaries, payable semi-monthly in accordance with the Company's regular payroll practices. The Executive's Base Salary will be reviewed annually by the Compensation Committee Board of Directors of the Company (the "Board") and may be adjusted in the Compensation Committee's discretion. 3.2. Annual Bonus Compensation. During the Employment Term, the Executive also shall be entitled to receive incentive compensation ("Bonus") in such amounts, ranging from 0% to 100% of Base Salary, and at such times as the Compensation Committee of the Board may determine in its discretion to award to him under any incentive compensation or other bonus plan or plans for senior executives of the Company as may be established by the Company from time to time (collectively, the "Executive Bonus Plan"). Such Bonus amounts shall be based upon the degree of achievement of Company earnings, sales growth and return on investment or other performance criteria established by the Compensation Committee of the Board. For any partial year (including 2004), the Bonus opportunity shall be prorated based upon the number of days worked during such year. 3.3. Stock Option Grants. (a) Matching Stock Option Award. As of the effective Date, the Company shall grant to the Executive a matching stock option award to purchase a number of shares of Company Common Stock equal to two times the number of shares of Company Common Stock purchased by the Executive as a long-term investment in the open market. This stock option award, granted as of the effective date, will assume that an investment purchase of 50,000 shares of WESCO's common stock will be completed in the first twelve (12) months following the effective date. In the event that less than 50,000 shares are purchased, options equal to twice the difference will not 2

vest and will be forfeited. If more than 50,000 shares are purchased within the first twelve (12) months following the effective date, a supplemental matching stock option award equal to two times the difference greater than 50,000 will be granted. These matching options shall time-vest on a ratable basis on the first, second and third annual anniversaries of the date of grant. The exercise price of the option grants shall be 100% of the fair market value of the Company's common stock as of the date of grant of the option, as determined in accordance with the Company's Long-Term Incentive Plan, and shall have a stated term of 9.75 years from the date of grant. Notwithstanding the foregoing, these options shall be subject to all of the terms and conditions of the Company's Long-Term Incentive Plan and an individual stock option agreement to be entered into by the Company and the Executive. (b) New Senior Executive Hire Stock Option Award. As of the Effective Date, the Company shall grant to the Executive a new senior executive hire stock option award to purchase up to 100,000 shares of Company Common Stock. The exercise price of this option shall be 100% of the fair market value of the option shares as of the Effective Date, as determined in accordance with the Company's Long-Term Incentive Plan, and shall have a stated term of 9.75 years from the date of grant. These options shall be subject to performance-vesting based on the annual achievement of a 5% corporate EBITDA margin in 2005 or a subsequent year. Notwithstanding the foregoing, this option award shall be subject to all of the terms and conditions of the Company's Long-Term Incentive Plan and an individual stock option agreement to be entered into by the Company and the Executive. (c) Future Stock Option Awards. Future stock option grants to the Executive shall be based upon performance and award guidelines established periodically by the Compensation Committee of the Board. 4. Expenses and Other Benefits. 4.1. Reimbursement of Expenses. During the Employment Term, the Executive shall be entitled to receive prompt reimbursement for all reasonable expenses incurred by him (in accordance with the policies and practices presently followed by the Company or as may be established by the Board for its senior executive officers) in performing services under this Agreement, provided that the Executive properly accounts for such expenses in accordance with the Company's policies. 4.2. Employee Benefits. During the Employment Term, the Executive shall be entitled to participate in and to receive benefits as a senior executive under all of the Company's employee benefit plans, programs and arrangements available to senior executives, subject to the eligibility criteria and other terms and conditions thereof, as such plans, programs and arrangements may be duly amended, terminated, approved or adopted by the Board from time to time. 4.3. Automobile Allowance. During the Employment Term, the Executive shall be entitled to an automobile allowance of $1,000 per month. 3

5. Termination of Employment. 5.1. Death. The Executive's employment under this Agreement shall terminate upon his death. 5.2. Termination by the Company. The Company may terminate the Executive's employment under this Agreement with or without Cause (as defined below). For purposes of this Agreement, the Company shall have "Cause" to terminate the Executive's employment under this Agreement and may complete such termination within 30 days after the Company gives notice to the Executive that it believes it has cause to terminate his employment by reason of any of the following: (a) a material breach of this Agreement by the Executive; (b) the Executive engaging in a felony or engaging in conduct which is in the good faith judgment of the Board, applying reasonable standards of personal and professional conduct, injurious to the Company, its customers, employees, suppliers, or shareholders; (c) the Executive's failure to timely and adequately perform his duties under the Agreement; or (d) the Executive's material breach of any manual or written policy, code or procedure of the Company. 5.3. Termination by the Executive. The Executive may terminate his employment under this Agreement with or without Good Reason (as defined below). If such termination is with Good Reason, the Executive shall give the Company written notice, which shall identify with reasonable specificity the grounds for the Executive's resignation and provide the Company with thirty (30) days from the day such notice is given to cure the alleged grounds for resignation contained in the notice. A termination shall not be for Good Reason if such notice is given by the Executive to the Company more than sixty (60) days after the occurrence of the event that the Executive alleges is Good Reason for his termination hereunder. For purposes of this Agreement, "Good Reason" shall mean any of the following to which the Executive shall not consent in writing: (a) a reduction in the Executive's Base Salary, excluding any reduction that occurs in connection with an across-the-board reduction of the salaries of the entire senior management team; (b) a relocation of the Executive's primary place of employment to a location more than 50 miles from Pittsburgh, Pennsylvania; or (c) any material reduction in the Executive's offices, titles, authority, duties or responsibilities. 5.4. Date of Termination. "Date of Termination" shall mean the earlier of (a) the date of expiration of the Employment Term (as set forth in Section 2) and (b) if the Executive's employment is terminated (i) by his death, the date of his death, or (ii) pursuant to the provisions of Section 5.2, Section 5.3 or Section 6, as the case may be, the date on which the Executive's employment with the Company actually terminates. 6. Disability. The Executive shall be determined to be "Disabled" (and the provisions of this Section 6 shall be applicable) if the Executive is unable to perform his duties under this Agreement on essentially a full-time basis for six (6) consecutive months by reason of a physical or mental condition (a "Disability") and, within thirty (30) days after the Company gives notice to the Executive that it intends to replace him due 4

to his Disability, the Executive shall not have returned to the performance of his duties on essentially a full-time basis. Upon a determination that the Executive is Disabled, the Company may replace the Executive without breaching this Agreement. 7. Compensation of the Executive upon Termination. 7.1. Death. If the Executive's employment under this Agreement is terminated by reason of his death, the Company shall pay to the person or persons designated by the Executive for that purpose in a notice filed with the Company, or, if no such person shall have been so designated, to his estate, the amount of (a) the Executive's accrued but unpaid Base Salary through the Date of Termination, (b) any accrued but unpaid Bonus; provided that such Bonus is determined to have been earned under the terms of the Executive Bonus Plan and provided that such Bonus shall be payable at such time as the bonuses of other senior executives are payable by the Company and (c) any other amounts that may be reimbursable by the Company to the Executive as expressly provided under this Agreement. Any amounts payable under this Section 7.1 shall be exclusive of and in addition to any payments which the Executive's widow, beneficiaries or estate may be entitled to receive pursuant to any employee benefit plan or program maintained by the Company. 7.2. Disability. In the event of the Executive's termination by reason of Disability pursuant to Section 6, the Executive shall continue to receive his Base Salary as well as all welfare benefits (on an equivalent basis to Section 7.4(a)(v) below) through the Date of Termination; provided, however, that such Base Salary payments and continued benefits shall be offset dollar-for-dollar by the amount of any disability income payments provided to the Executive under any Company disability policy to the extent that such disability insurance was funded by the Company. 7.3. By the Company for Cause or the Executive Without Good Reason. If the Executive's employment is terminated by the Company for Cause, or if the Executive terminates his employment other than for Good Reason, the Company shall pay to the Executive, within thirty (30) days of the Date of Termination, the amount of any accrued but unpaid Base Salary through the Date of Termination and the Company thereafter shall have no further obligation to the Executive under this Agreement, other than for payment of any amounts accrued and vested under any employee benefit plans or programs of the Company. 7.4. By the Executive for Good Reason or the Company other than for Cause. (a) Severance Benefits on Non-Change in Control Termination. Subject to the provisions of Section 7.4(b) and Section 7.4(d), if prior to the occurrence of a Change in Control or more than one (1) year after the occurrence of a Change in Control the Company terminates the Executive's employment without Cause, or the Executive terminates his employment for Good Reason, then the Executive shall be entitled to the following benefits (the "Severance Benefits"): 5

(i) the sum of his accrued but unpaid Base Salary through the Date of Termination, that amount being payable in a single lump sum cash payment within thirty (30) days of the Date of Termination; (ii) a cash amount equal to the Executive's pro rata Bonus for the fiscal year in which the Date of Termination occurs, if such Bonus is deemed earned under the Executive Bonus Plan, payable at such time as bonuses for the annual period are paid to other executive officers of the Company (such pro rata Bonus shall be based on a fraction, the numerator of which is the number of days from the first day of the fiscal year of the Company in which such termination occurs through and including the Date of Termination and the denominator of which is 365) (iii) a cash amount equal to 1.5 times the Executive's Monthly Base Salary in effect at the Date of Termination that total amount being payable in monthly installments for the greater of (A) the remainder of the Employment Term or (B) eighteen (18) months following the Date of Termination. (iv) the Executive shall be fully vested in his stock options except for any stock options that will remain unvested and be forfeited if their vesting is specifically conditioned on the achievement of operational and/or financial performance criteria that have not been met. Any and all vested stock options will remain excercisable for a period of 60 days following the date of termination; and (v) the Company shall pay the full cost of the Executive's COBRA continuation coverage as such coverage is required to be continued under applicable law; provided, however, that, notwithstanding the foregoing, the benefits described in this Section 7.4(a)(v) may be discontinued prior to the end of the period provided in this subsection (v) to the extent, but only to the extent, that the Executive receives substantially similar benefits from a subsequent employer. (b) Change in Control Benefits. Subject to the provisions of Section 7.4(b) and Section 7.4(d), if within the one (1)-year period following the occurrence of a Change in Control the Company terminates the Executive's employment without Cause, or the Executive terminates his employment for Good Reason, then the Executive shall be entitled to the following Severance Benefits: (i) the sum of his accrued but unpaid Base Salary through the Date of Termination, that amount being payable in a single lump sum cash payment within thirty (30) days of the Date of Termination; (ii) a cash amount equal to the Executive's pro rata Bonus for the fiscal year in which the Date of Termination occurs, if such Bonus is deemed earned under the Executive Bonus Plan, payable at such time as bonuses for the annual period are paid to other executive officers of the Company (such pro rata Bonus shall be based on a fraction, the numerator of which is the number of days from the first day of the fiscal year of the Company in which such termination occurs through and 6

including the Date of Termination and the denominator of which is 365); and (iii) a cash amount equal to 1.5 times the Executive's Monthly Base Salary in effect at the Date of Termination, that amount being payable in monthly installments for twenty-four (24) months following the Date of Termination; (iv) the Executive shall be fully vested in his stock options, and vested stock options shall remain exercisable by the Executive for one year following the Date of Termination unless the transaction documents relating to the Change in Control provide for the earlier expiration of such stock options. (v) the Company shall pay the full cost of the Executive's COBRA continuation coverage as such coverage is required to be continued under applicable law; provided, however, that, notwithstanding the foregoing, the benefits described in this Section 7.4(b)(v) may be discontinued prior to the end of the period provided in this subsection (v) to the extent, but only to the extent, that the Executive receives substantially similar benefits from a subsequent employer. (c) Definition of Change in Control. For purposes of this Agreement, a "Change in Control" shall have the meaning given to such term in the Company's Long-Term Incentive Plan. (d) Conditions to Receipt of Severance Benefits under Section 7.4(a). (i) Release. As a condition to receiving any Severance Benefits to which the Executive may otherwise be entitled under Section 7.4(a) or (b), the Executive shall execute a release (the "Release"), which shall include an affirmation of the restrictive covenants set forth in Section 8 and a non-disparagement provision, in a form and substance satisfactory to the Company, of any claims, whether arising under federal, state or local statute, common law or otherwise, against the Company and its direct or indirect subsidiaries which arise or may have arisen on or before the date of the Release, other than any claims under this Agreement or any rights to indemnification from the Company and its direct or indirect subsidiaries pursuant to any provisions of the Company's (or any of its subsidiaries') articles of incorporation or by-laws or any directors and officers liability insurance policies maintained by the Company. If the Executive fails or otherwise refuses to execute a Release within a reasonable time after the Company's request to do so, the Executive shall not be entitled to any Severance Benefits, or any other benefits provided under this Agreement and the Company shall have no further obligations with respect to the payment of those benefits except as may be required by law. (ii) Limitation on Benefits. If, following a termination of employment that gives the Executive a right to the payment of Severance Benefits under Section 7.4(a) or (b) the Executive violates in any material respect any of the covenants in Section 8 or as otherwise set forth in the Release, the Executive shall have no further right or claim to any payments or other benefits to which the Executive 7

may otherwise be entitled under Section 7.4(a) or (b) from and after the date on which the Executive engages in such activities and the Company shall have no further obligations with respect to such payments or benefits; provided, however, that the covenants in Section 8 shall continue in full force and effect. 7.5. Severance Benefits Not Includable for Employee Benefits Purposes. Except to the extent the terms of any applicable benefit plan, policy or program provide otherwise, any benefit programs of the Company that takes into account the Executive's income shall exclude any and all severance payments and benefits provided under this Agreement. 7.6. Exclusive Benefits. The Severance Benefits payable under Section 7.4(a) and (b) if they become applicable under the terms of this Agreement, shall be in lieu of any other severance or similar benefits that would otherwise be payable under any other agreement, plan, program or policy of the Company. 7.7 Certain Additional Payments by the Company. (a) Calculation of Gross-Up Payment. Notwithstanding anything in this Agreement to the contrary, the Company's regular outside independent public accounting firm or its regular outside law firm (the "Professional Firm") shall determine, promptly following the occurrence of a Change in Control, whether any economic benefit, payment or distribution by the Company to or for the benefit of the Executive, whether paid, payable, distributed or distributable pursuant to the terms of this Agreement or otherwise (a "Payment"), would be subject to the excise tax imposed by Section 4999 of the Internal Revenue Code of 1986, as amended (the "Code"), (such excise tax referred to in this Agreement as the "Excise Tax"). In the event it is determined that any Payments would be subject to the Excise Tax, then the Executive shall be entitled to receive an additional payment (a "Gross-Up-Payment") in an amount such that after payment by the Executive of all applicable federal, state and local income and excise taxes, the Executive retains an amount equal to the amount he would have retained had one-half (1/2) of the Excise Tax been imposed upon the Payment; provided, however, that the foregoing gross-up provision shall not apply in the event that the Professional Firm determines that the benefits to the Executive under this Agreement on an after-tax basis (i.e., after federal, state and local income and excise taxes) if such provision is not applied would exceed the after-tax benefits to the Executive if Payments were reduced (but not below zero) such that the value of the aggregate Payments were one dollar ($1) less than the maximum amount of Payments which the Executive may receive without becoming subject to the tax imposed by Section 4999 of the Code. The initial Gross-Up Payment, if any, as determined pursuant to this Section 7.7(a), shall be paid to the Executive within thirty (30) days of the Date of Termination or, if later, within five (5) business days of the receipt of the Professional Firm's determination. With respect to all determinations made by the Professional Firm under this Section 7.7, the Professional Firm shall provide detailed supporting calculations both to the Company and the Executive within thirty (30) business days of the Date of Termination, if applicable, or such earlier time as is 8

requested by the Company. All determinations by the Professional Firm under this Agreement shall be binding upon the Company and the Executive. (b) Underpayment. As a result of the uncertainty in the application of Section 4999 of the Code at the time of the initial determination by the Firm, it is possible that Gross-Up Payments that have not been made by the Company should have been made ("Underpayment"). In the event that the Executive is required to make a payment of any Excise Tax, the Professional Firm shall determine the amount of the Underpayment that has occurred and any such Underpayment shall be promptly paid by the Company to or for the benefit of the Executive. 8. Restrictive Covenants. 8.1. Confidential Information. The Executive hereby acknowledges that in connection with his employment by the Company he will be exposed to and may obtain certain information (including, without limitation, procedures, memoranda, notes, records and customer and supplier lists whether such information has been or is made, developed or compiled by the Executive or otherwise has been or is made available to him) regarding the business and operations of the Company and its subsidiaries or affiliates. The Executive further acknowledges that such information and procedures are unique, valuable, considered trade secrets and deemed proprietary by the Company. For purposes of this Agreement, such information and procedures shall be referred to as "Confidential Information." The Executive agrees that all Confidential Information is and shall remain the property of the Company. The Executive further agrees, except as otherwise required by law and for disclosures occurring in the good faith performance of his duties for the Company, while employed by the Company hereunder and thereafter, to hold in the strictest confidence all Confidential Information, and not to, directly or indirectly, duplicate, sell, use, lease, commercialize, disclose or otherwise divulge to any person or entity any portion of the Confidential Information or use any Confidential Information for his own benefit or profit or allow any person, entity or third party, other than the Company and authorized executives of the same, to use or otherwise gain access to any Confidential Information. 8.2.

Non Competition. During the Employment Term and for a period of twenty-four (24) months after the Date of Termination, the Executive shall not, unless he receives the prior written consent of the Company, directly or indirectly, own an interest in, manage, operate, join, control, lend money or render financial or other assistance to, participate in or be connected with, as an officer, employee, partner, 9

stockholder, consultant or otherwise, or engage in any activity or capacity (collectively, the "Competitive Activities") with respect to any individual, partnership, limited liability company, firm, corporation or other business organization or entity (each, a "Person"), that is engaged directly or indirectly in the distribution of electrical construction products or electrical and industrial maintenance, repair and operating supplies, or the provision of integrated supply services, or that is in competition with any of the business activities of the Company or its direct or indirect subsidiaries anywhere in the world; provided, however, that the foregoing (a) shall not apply with respect to any line-of-business in which the Company or its direct or indirect subsidiaries was not engaged on or before the Date of Termination, and (b) shall not prohibit the Executive from owning, or otherwise having an interest in, less than one percent (1%) of any publicly-owned entity or three percent (3%) of any private equity fund or similar investment fund that invests in companies engaged in the distribution of electrical construction products or electrical and industrial maintenance, repair and operating supplies, or the provision of integrated supply services, provided the Executive has no active role with respect to any investment by such fund in any Person referred to in this Section 8.3. 8.4. Non-Solicitation. During the Employment Term and for a period of twenty-four (24) months after the Date of Termination, the Executive shall not, whether for his own account or for the account of any other Person (other than the Company or its direct or indirect subsidiaries), intentionally solicit, endeavor to entice away from the Company or its direct or indirect subsidiaries, or otherwise interfere with the relationship of the Company or its direct or indirect subsidiaries with, (a) any person who is employed by the Company or its direct or indirect subsidiaries (including any independent sales representatives or organizations), or (b) any client or customer of the Company or its direct or indirect subsidiaries. 8.5. Assignment of Developments. If at any time or times during the Executive's employment, whether during work hours or off-duty hours, the Executive shall (either alone or with others) make, conceive, create, discover, invent or reduce to practice any Development (as defined below) that (i) relates to the business of the Company or any customer of or supplier to the Company or any of the products or services being developed, manufactured or sold by the Company or which may be used in relation therewith; or (ii) results from tasks assigned to the Executive by the Company; or (iii) results from the use of premises or personal property (whether tangible or intangible) owned, leased or contracted for by the Company, then all such Developments and the benefits thereof are and shall immediately become the sole and absolute property of the Company and its assigns, as works made for hire or otherwise. The term "Development" shall mean any invention, modification, discovery, design, development, improvement, process, software program, work of authorship, documentation, technique, know-how, trade secret or intellectual property right whatsoever or any interest therein (whether or not patentable or registerable under copyright, trademark or similar statutes or subject to analogous protection). The Executive shall promptly disclose to the Company (or any persons designated by it) each such Development. The Executive hereby assign all rights (including, but not limited to, rights to inventions, patentable subject matter, copyrights and trademarks) 10

the Executive may have or may acquire in the Developments and all benefits and/or rights resulting therefrom to the Company and its assigns without further compensation and shall communicate, without cost or delay, and without disclosing to others the same, all available information relating thereto (with all necessary plans and models) to the Company. 8.6. Injunctive Relief. The Executive acknowledges that a breach of any of the covenants contained in this Section 8 may result in material, irreparable injury to the Company for which there is no adequate remedy at law, that it shall not be possible to measure damages for such injuries precisely and that, in the event of such a breach or threat of breach, the Company shall be entitled to obtain a temporary restraining order and/or a preliminary or permanent injunction restraining the Executive from engaging in activities prohibited by this Section 8 or such other relief as may be required to specifically enforce any of the covenants in this Section 8. To the extent that the Company seeks a temporary restraining order (but not a preliminary or permanent injunction), the Executive agrees that a temporary restraining order may be obtained ex parte. 8.7. Adjustment of Covenants. The parties consider the covenants and restrictions contained in this Section 8 to be reasonable. However, if and when any such covenant or restriction is found to be void or unenforceable and would have been valid had some part of it been deleted or had its scope of application been modified, such covenant or restriction shall be deemed to have been applied with such modification as would be necessary and consistent with the intent of the parties to have made it valid, enforceable and effective. 9. Miscellaneous. 9.1. Assignment; Successors; Binding Agreement. This Agreement may not be assigned by either party, whether by operation of law or otherwise, without the prior written consent of the other party, except that any right, title or interest of the Company arising out of this Agreement may be assigned to any corporation or entity controlling, controlled by, or under common control with the Company, or succeeding to the business and substantially all of the assets of the Company or any affiliates for which the Executive performs substantial services. Subject to the foregoing, this Agreement shall be binding upon and shall inure to the benefit of the parties and their respective heirs, legatees, devisees, personal representatives, successors and assigns. 9.2. Modification and Waiver. Except as otherwise provided below, no provision of this Agreement may be modified, waived, or discharged unless such waiver, modification or discharge is duly approved by the Board and is agreed to in writing by the Executive and such officer(s) as may be specifically authorized by the Board to effect it. Notwithstanding the foregoing, in the event that the provisions of the Company's Corporate Governance Guidelines related to executive employment agreements are revised during the Employment Term, the Company may make changes to this Agreement, without the consent of the Executive, in order to conform 11

this Agreement with such revised Guidelines. No waiver by any party of any breach by any other party of, or of compliance with, any term or condition of this Agreement to be performed by any other party, at any time, shall constitute a waiver of similar or dissimilar terms or conditions at that time or at any prior or subsequent time. 9.3. Entire Agreement. This Agreement embodies the entire understanding of the parties hereof, and supersedes all other oral or written agreements or understandings between them regarding the subject matter hereof. No agreement or representation, oral or otherwise, express or implied, with respect to the subject matter of this Agreement, has been made by either party which is not set forth expressly in this Agreement. 9.4. Governing Law. The validity, interpretation, construction and performance of this Agreement shall be governed by the laws of the Commonwealth of Pennsylvania other than the conflict of laws provision thereof. 9.5. Consent to Jurisdiction and Service of Process. (a) Disputes Other Than Those Under Section 8. In the event of any dispute relating to this Agreement, other than a dispute relating solely to Section 8, the parties shall use their best efforts to settle the dispute, claim, question, or disagreement. To this effect, they shall consult and negotiate with each other in good faith and, recognizing their mutual interests, attempt to reach a just and equitable solution satisfactory to both parties. If such a dispute cannot be settled through negotiation, the parties agree first to try in good faith to settle the dispute by mediation administered by the American Arbitration Association under its Commercial Mediation Rules before resorting to arbitration, litigation, or some other dispute resolution procedure. If the parties do not reach such solution through negotiation or mediation within a period of sixty (60) days, then, upon notice by either party to the other, all disputes, claims, questions, or differences shall be finally settled by arbitration administered by the American Arbitration Association in accordance with the provisions of its Commercial Arbitration Rules. The arbitrator shall be selected by agreement of the parties or, if they do not agree on an arbitrator within thirty (30) days after either party has notified the other of his or its desire to have the question settled by arbitration, then the arbitrator shall be selected pursuant to the procedures of the American Arbitration Association (the "AAA") in Pittsburgh, Pennsylvania. The determination reached in such arbitration shall be final and binding on all parties. Enforcement of the determination by such arbitrator may be sought in any court of competent jurisdiction. Unless otherwise agreed by the parties, any such arbitration shall take place in Pittsburgh, Pennsylvania, and shall be conducted in accordance with the Commercial Arbitration Rules of the AAA. (b) Disputes Under Section 8. In the event of any dispute, controversy or claim between the Company and the Executive arising out of or relating to the interpretation, application or enforcement of the provisions of Section 8, the Company and the Executive agree and consent to the personal jurisdiction of the County Courts 12

in Allegheny County, Pennsylvania and/or the United States District Court for the Western District of Pennsylvania for resolution of the dispute, controversy or claim, and that those courts, and only those courts, shall have exclusive jurisdiction to determine any dispute, controversy or claim related to, arising under or in connection with Section 8 of this Agreement. The Company and the Executive also agree that those courts are convenient forums for the parties to any such dispute, controversy or claim and for any potential witnesses and that process issued out of any such court or in accordance with the rules of practice of that court may be served by mail or other forms of substituted service to the Company at the address of its principal executive offices and to the Executive at his last known address as reflected in the Company's records. 9.6. Withholding of Taxes. The Company shall withhold from any amounts payable under the Agreement all federal, state, local or other taxes as legally shall be required to be withheld. 9.7. Notice. All notices, requests, demands and other communications hereunder shall be in writing and shall be deemed to have been duly given if delivered by hand, mailed within the continental United States by first class certified mail, return receipt requested, postage prepaid or sent via a nationally-recognized overnight courier or by facsimile transmission, addressed as follows: (a) to the Company, to: Wesco International, Inc.

Severability. The invalidity or unenforceability of any provision or provisions of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement, which shall remain in full force and effect. 9.9. Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed to be an original but all of which together shall constitute one and the same instrument. 13

9.10. Headings. The headings used in this Agreement are for convenience only, do not constitute a part of the Agreement, and shall not be deemed to limit, characterize, or affect in any way the provisions of the Agreement, and all provisions of the Agreement shall be construed as if no headings had been used in the Agreement. 9.11.
