7 MEETINGS AND COMMITTEES OF THE BOARD The Board has three standing committees: an Executive Committee, an Audit Committee and a Compensation Committee. The Board does not have a nominating committee. The full Board held seven meetings in 1999. The Executive Committee consists of Messrs. Cheshire, Haley, Singleton and Stern, with Mr. Singleton serving as Chairman. It is responsible for overseeing the management of the affairs and business of the Company and has been delegated authority to exercise the powers of the Board during intervals between Board meetings. The Executive Committee held two meetings in 1999. Each director attended 75% or more of the aggregate number of the total number of meetings of the Board and the committees of the Board on which he served, other than Mr. Tarr. The Audit Committee consists of Messrs. Cheshire and Tarr, with Mr. Tarr serving as Chairman. It is responsible for recommending the firm to be appointed as independent accountants to audit the Company's financial statements and to perform services related to the audit; reviewing the scope and results of the audit with the independent accountants; reviewing with the management and the independent accountants the Company's year end operating results; considering the adequacy of the internal accounting, audit and control procedures of the Company, reviewing the non-audit services to be performed by the independent accountants, if any, and considering the effect of such performance on the accountants' independence. The Audit Committee held four meetings in 1999. The Compensation Committee consists of Messrs. Stern, Singleton, Tarr, Tutrone and Way, with Mr. Stern serving as Chairman. It is responsible for the review, recommendation and approval of compensation arrangements for directors and executive officers, for the approval of such arrangements for other senior level employees, and for the administration of certain benefit and compensation plans and arrangements of the Company. The Compensation Committee held two meetings in 1999. COMPENSATION OF DIRECTORS Members of the Board who are also employees of the Company do not receive cash compensation for their services as directors. Each director of the Company who is not an employee of the Company or any of its subsidiaries or Cypress is entitled to receive an annual director's fee of $25,000. Each director of the Company meeting the criteria during 1999 did receive $25,000. The Company established the Deferred Compensation Plan for Non-Employee Directors in 1999 under which non-employee directors can elect to defer 25% or more of the annual director's fee. Amounts deferred under this arrangement will, on the deferral date, be converted into stock units (common stock equivalents) which will be credited to a bookkeeping account in the director's name. For purposes of determining the number of stock units to be credited to a director for a particular year, the average of the high and low trading prices of the Common Stock on the first trading day in January of that year will be used. Distribution of deferred stock units will be made in a lump sum or installments, in the form of shares of Common Stock, in accordance with the distribution schedule selected by the director at the time the deferral election is made. 5

EMPLOYMENT AGREEMENTS Employment Agreement with the Chief Executive Officer. The Company is a party to an employment agreement with Mr. Haley providing for a rolling employment term of three years. Pursuant to this agreement, Mr. Haley is entitled to an annual base salary of $500,000 and an annual incentive bonus equal to a percentage of his annual base salary ranging from 0% to 200%. The actual amount of Mr. Haley's annual incentive bonus will be determined based upon the Company's financial performance as compared to the annual performance objectives established for the relevant fiscal year. If Mr. Haley's employment is terminated by the Company without "cause," by Mr. Haley for "good reason" or as a result of Mr. Haley's death or disability, 7

10 Mr. Haley is entitled to continued payments of his average annual base salary and his average annual incentive bonus, reduced by any disability payments for the three-year period, or in the case of a termination due to Mr. Haley's death or disability, the two-year period, following such termination, and continued welfare benefit coverage for the two-year period following such termination. In addition, in the event of any such qualifying termination, all outstanding options held by Mr. Haley will become fully vested. The agreement further provides that, in the event of the termination of Mr. Haley's employment by the Company without cause or by Mr. Haley for good reason, in either such case, within the two-year period following a "change in control" of the Company, in addition to the termination benefits described above, Mr. Haley is entitled to receive continued welfare benefit coverage and payments in lieu of additional contributions to the Company's Retirement Savings Plan and Deferred Compensation Plan for the three year period following such change in control. The Company has agreed to provide Mr. Haley with an excise tax gross up with respect to any excise taxes Mr. Haley may be obligated to pay pursuant to Section 4999 of the United States Internal Revenue Code of 1986 on any excess parachute payments. In addition, following a change in control, Mr. Haley is entitled to a minimum annual bonus equal to 50% of his base salary, and the definition of "good reason" is modified to include certain additional events. The agreement also contains customary covenants regarding nondisclosure of confidential information and non-competition and non-solicitation restrictions. REPORT OF COMPENSATION COMMITTEE ON EXECUTIVE COMPENSATION Responsibilities and Goals: The Compensation Committee, composed of non-employee directors, has the responsibility of administering executive compensation and benefit programs, policies and practices. The Committee consists of Messrs. Stern, Singleton, Tarr, Tutrone and Way, with Mr. Stern serving as Chairman. The Committee engages the assistance of outside consultants and third-party surveys in its consideration of compensation levels and incentive plan designs. On an annual basis, the Committee reviews and approves the compensation and benefit programs for the executive officers, including the Chairman and Chief Executive Officer. Executive Officer Compensation: The objective of the Company's compensation program for executive officers (including Mr. Haley, Chief Executive Officer) is to motivate and reward executive management for achieving high levels of business performance and outstanding financial results. This reflects the Company's commitment to attract, develop, retain and motivate the high caliber of executive required to perform in the competitive distribution industry, and to ensure positive business performance and continued growth in shareholder value. 8

11 The Company's compensation program for executive officers consists of a base salary, annual incentive bonuses and long-term incentives. Executives have significant amounts of compensation at risk, based on performance. Executives are also encouraged to maintain a significant equity stake in the Company since this most closely aligns the interests of management with those of the shareholders. Each of the Company's executive officers maintains an equity investment in the Company, exclusive of stock options, of at least two times their base salary. Mr. Haley's equity ownership is greater than 18 times his base salary. o Base salaries for the Company's executives are targeted at the median of similarly sized industrial services companies. Salaries for each executive are reviewed annually, taking into account factors such as changes in duties and responsibilities, individual performance and changes in the competitive marketplace. o Annual incentives are awarded for successfully achieving financial and operational goals of the Company which are established at the beginning of the year. o Long-term incentives are generally granted in the form of stock options. The Committee believes that stock options are the most effective long-term link between executive performance and shareholder value. CEO Compensation In determining the 1999 compensation of Mr. Haley, the Company's Chief Executive Officer, the Committee assessed his individual performance and leadership, as reflected in the Company's financial and operating performance (including such factors as sales, operating income, earnings per share, cash flow and capitalization), new business development initiatives and acquisition programs. The Committee recognized and acknowledged the Company's record levels of sales and operating earnings, and the significant effort required to accomplish the Company's initial public offering and improved financial structure. The Company, however, maintains demanding performance based standards, and since performance targets were not fully achieved, the annual cash bonus payments for Mr. Haley and other Named Executive Officers were significantly reduced in relation to prior years. In 1999, Mr. Haley received a base salary of $500,000 and a cash bonus in the amount of $200,000. No stock option awards were granted to Mr. Haley under the LTIP (Long Term Incentive Plan) in 1999. This information is also shown in the Summary Compensation Table in this Proxy Statement. 9

12 Conclusions The Committee's goal is to maintain compensation and benefit programs that are competitive within the distribution industry and clearly linked to shareholder value. The Committee believes that the 1999 compensation levels disclosed in this Proxy Statement are reasonable and appropriate. The Committee intends to ensure that compensation paid to its executive officers is within the limits of, or exempt from, the deductibility limits of 162(m) of the Internal Revenue Code and expects that all compensation will be deductible. However, it reserves the right to pay compensation that is not deductible if it determines that to be in the best interests of the Company and the shareholders. RESPECTFULLY SUBMITTED: COMPENSATION COMMITTEE James A. Stern, Chairman James L. Singleton Robert J. Tarr, Jr. Anthony D. Tutrone Kenneth L. Way COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION No member of the Compensation Committee is an officer or employee of the Company. No member of the Committee has a current or prior relationship, and no officer who is a statutory insider of the Company has a relationship to any other company, required to be described under the Securities and Exchange Commission rules relating to disclosure of executive compensation. 10

14 CERTAIN TRANSACTIONS AND RELATIONSHIPS WITH THE COMPANY AMENDED AND RESTATED REGISTRATION AND PARTICIPATION AGREEMENT. In connection with the Company's recapitalization in 1998, an investor group led by The Cypress Group L.L.C. ("Cypress"), which included, among others, Chase Capital Partners and Co-Investment Partners, L.P. and Clayton, Dubilier & Rice ("CD&R"), Westinghouse and the Company entered into a registration and participation agreement (the "Registration and Participation Agreement"), which amended and restated the previous agreement among CD&R, Westinghouse and the Company, to reflect, among other things, the succession of the investor group to CD&R's and Westinghouse's rights and obligations thereunder. Pursuant to the Registration and Participation Agreement, the investor group and the management stockholders have the right, under certain circumstances and subject to certain conditions, to request that the Company register under the Securities Act shares of common stock held by them. Subject to certain conditions and exceptions, the investor group and the management stockholders also have the right to require that shares of common stock held by them be included in any registration under the Securities Act commenced by the Company. The Registration and Participation Agreement provides that the Company will pay all expenses in connection with the first three registrations requested by the investor group and the management stockholders. The Registration and Participation Agreement also provides that the Company will indemnify the investors and the management stockholders and their affiliates for certain liabilities they may incur under the securities laws. In addition, the Registration and Participation Agreement provides that so long as Cypress owns any of our securities, Cypress shall have the right to designate one director to our Board of Directors and the Board of Directors of WESCO Canada. At the time we entered the Registration and Participation Agreement, Cypress was not affiliated with WESCO, and we believe the transaction was made on terms no less favorable to us than we could have obtained from an unaffiliated party. MANAGEMENT STOCKHOLDERS. Each member of management who holds common stock is a party to a stock subscription agreement with the Company which provides that each management stockholder is entitled to certain benefits of, and bound by certain obligations in, the Registration and Participation Agreement, including certain registration rights thereunder. A portion of the purchase price paid for common stock purchased by certain management stockholders has been financed by full-recourse bank loans guaranteed by WESCO. As of December 31, 1999, Messrs. Haley, Mehta, Swed, Goodwin, Kramp, Piraino, Van and Vanderhoff had outstanding loans guaranteed by the Company in the amount of $3,054,872, $0, $0, $0, $0, $0, $49,686 and $0 respectively, and since January 1, 1999, the largest amounts outstanding under such loans were $3,054,872, $899,944, $343,200, $260,572, $68,700, $266,634, $49,686 and $282,832 respectively. Messrs. Kramp and Piraino are no longer with the Company. 12
