board committees, corporate organization, selection and succession planning for officers and key executives, programs for training and development of executive-level employees, and stockholder proposals regarding these matters. The board of directors does not have a nominating committee. The full board of directors nominates candidates for membership on the board of directors. Trex Company's bylaws provide that any stockholder wishing to nominate persons for election as directors at an annual meeting must deliver to the Secretary of Trex Company at Trex Company's principal office in Winchester, Virginia, a written notice of the stockholder's intention to make such a nomination. The stockholder generally is required to furnish the notice no earlier than 120 days and no later than 90 days before the first anniversary of the preceding year's annual meeting. The notice must include the following information: (1) such information regarding each proposed nominee as would be required to be disclosed under SEC rules and regulations in solicitations of proxies for the election of directors in an election contest or otherwise; (2) the written consent of each proposed nominee to serve as a director of Trex Company; and (3) as to the stockholder giving the notice and the beneficial owner, if any, of common stock on whose behalf the nomination is made, (a) the name and address of record of such stockholder and the name and address of such beneficial owner, (b) the class and number of shares of Trex Company's capital stock that are owned beneficially and of record by such stockholder and such beneficial owner, (c) a representation that the stockholder is a holder of record of Trex Company's capital stock entitled to vote at such meeting and intends to appear, in person or by proxy, at the meeting to propose such nomination and (d) a representation whether the stockholder or the beneficial owner, if any, intends or is part of a group which intends to (A) deliver a proxy statement or form of proxy to holders of at least the percentage of Trex Company's outstanding capital stock required to elect the nominee or (B) otherwise solicit proxies for stockholders in support of such nomination. Trex Company may require any proposed nominee to furnish such other information as Trex Company may reasonably require to determine the eligibility of such proposed nominee to serve as a director of Trex Company. Director Compensation Fees. Under Trex Company's Amended and Restated 1999 Incentive Plan for Outside Directors, referred to in this proxy statement as the "Outside Director Plan," directors who are not employees of Trex Company receive an annual fee of $40,000 for their service on the board of directors and its committees. Before January 1, 2001, the annual fee was $25,000. Each non-employee director may elect to receive up to one-half of this annual fee in cash and up to all of the fee in the form of options to purchase common stock issued under the Stock Incentive Plan. The value of the options issued in payment of any portion of a non-employee director's annual fee is determined in accordance with the Black-Scholes valuation model. For fiscal 2001, Mr. Andrews, Mr. Martin and Ms. Robinson, Trex Company's three non-employee directors, received $20,000, $30,000, and $20,000, respectively, of their 2001 annual fee in the form of stock options.

The Outside Director Plan is administered by an administrative committee of the board of directors consisting of Trex Company's President and Trex Company's Chief Financial Officer. Stock Option Grants. Trex Company's current policy is to grant non-employee directors options to purchase 1,500 shares of common stock upon their initial appointment to the board of directors. The options are granted under the Stock Incentive Plan. 8

The exercise price per share under each option granted to a non-employee director upon appointment or in payment of annual fees is the fair market value of the common stock on the option grant date. Each such option vests with respect to one-fourth of the shares subject to the option on each of the first, second, third and fourth anniversaries of the option grant date. No option is exercisable more than ten years from the option grant date. The options will terminate after the expiration of specified periods following the termination of the optionee's service as a non-employee director, whether by reason of death, disability, retirement or otherwise.

Each such option will vest with respect to one-fourth of the shares subject to the option on each of the first, second, third and fourth 10

anniversaries of the date of grant. The Stock Incentive Plan permits limited donative transfers of non-qualified options to members of the optionee's immediate family and related trusts and similar entities, to the extent permitted by the board of directors. (2) The term of each option may not exceed ten years. (3) The potential realizable value is calculated based on the fair market value on the date of grant, which is equal to the exercise price of the option, assuming that the shares appreciate in value from the option grant date compounded annually until the end of the option term at the rate specified, 5% or 10%, and that the option is exercised and sold on the last day of the option term for the appreciated share price. Potential realizable value is net of the option exercise price. The assumed rates of appreciation are specified in the rules and regulations of the SEC and do not represent Trex Company's estimate or projection of future prices of the shares. There is no assurance provided to any named executive officer or any other holder of common stock that the actual stock price appreciation over the term of the applicable options will be at the assumed 5% and 10% levels or at any other defined level.

Report of the Compensation and Governance Committee The compensation and governance committee of the Trex Company, Inc. board of directors, which is composed exclusively of non-employee directors, offers this report regarding its executive compensation policy and compensation program in effect for fiscal 2001 for Trex Company's Chief Executive Officer, who is the President, and Trex Company's other executive officers. This report and the performance graph on page 14 are not soliciting materials, are not deemed filed with the SEC and are not incorporated by reference in any filing of Trex Company under the Securities Act of 1933 or the Securities Exchange Act of 1934, whether made before or after the date of this proxy statement and irrespective of any general incorporation language in any such filing. 11

Compensation Policy. The overall goal of the committee is to develop compensation policies and practices that support the attainment of Trex Company's strategic business objectives. The committee uses the services of independent executive compensation consultants in developing and evaluating compensation plans to achieve these objectives. The committee compares executive compensation levels for the chief executive officer and Trex Company's other executive officers to the compensation of executives employed by companies considered to be in Trex Company's peer group. The committee also compares Trex Company's short-term and long-term results to the performance of comparable companies. Trex Company's executive compensation program includes a base salary, annual cash bonuses and long-term incentive compensation in the form of stock option awards. Overall, these programs are intended to link executive compensation to Trex Company's performance. The committee believes that a substantial portion of cash compensation should be tied to performance-based objectives. To encourage equity ownership by Trex Company's executives and to link executive compensation with increases in stockholder value, the committee's policy is to provide that a significant portion of total executive compensation will be in the form of periodic stock option awards. Base Salary. Base salaries of executives are initially determined by evaluating the responsibilities of the position, the experience and knowledge of the executive, and the competitive marketplace for executive talent, including a comparison to base salaries for comparable positions at public companies in Trex Company's peer group. Base salaries for executive officers are reviewed annually by the committee based upon, among other things, individual performance and responsibilities. Annual Cash Bonuses. Trex Company pays annual cash bonuses to its executive officers based upon Trex Company's achievement of a net income objective. This objective is established at a level which is intended to assure that, if achieved, the level will represent a significant improvement in stockholder value. Executive officers have the opportunity to earn cash bonuses equal to a varying percentage of their base salary, depending upon the attainment of this objective. Applying the bonus formula specified for fiscal 2001, the committee did not approve an annual bonus for the chief executive officer or for the other executive officers. In determining the amount of stock option awards under the 1999 Stock Option and Incentive Plan, the committee considers each executive's current performance and anticipated future contributions to Trex Company's performance, as well as the amount and terms of the options previously granted to the executive by Trex Company. The committee in fiscal 2002 approved the grant of stock options under the 1999 Stock Option and Incentive Plan for a total of 15,000 shares of common stock to the executive officers in the aggregate, excluding the chief executive officer, who did not receive a stock option grant. The grant of stock options to the executive officers in fiscal 2002 was based on the committee's assessment of both the past contributions of the executive officers and their anticipated role in increasing stockholder value. All stock options granted to executive officers in fiscal 2002 were non-qualified stock options with an exercise price that was equal to the fair market value of Trex Company's common stock on the date of grant. The options increase in value only to the extent of appreciation in the common stock, thereby providing a clear link to enhancement of stockholder value. To emphasize the long-term incentive provided by these stock options, the options vest in equal increments over a four-year period. 12

Potential Effect of Section 162(m) of the Internal Revenue Code. Section 162(m) of the Internal Revenue Code of 1986 generally sets a limit of $1 million on the amount of compensation paid to executive employees (other than enumerated categories of compensation, including performance-based compensation) that may be deducted by a publicly traded company. The committee's policy is to seek to qualify executive compensation for deductibility to the extent that such a policy is consistent with Trex Company's overall objectives and executive compensation policy. Compensation attributable to stock options granted under the 1999 Stock Option and Incentive Plan currently is excluded from the $1 million limit as "qualified performance-based compensation" contained in applicable Treasury regulations. The committee believes that no compensation for fiscal 2001 is at risk of not being fully deductible. Respectfully submitted, THE COMPENSATION AND GOVERNANCE COMMITTEE William F. Andrews (Chairman) William H. Martin, III Patricia B. Robinson Compensation and Governance Committee Interlocks and Insider Participation The compensation and governance committee of the board of directors during fiscal 2001 was composed of William F. Andrews, who is the Chairman, William H. Martin, III and Patricia B. Robinson. No member of the compensation and governance committee was an officer or employee of Trex Company or any subsidiary of Trex Company during fiscal 2001. There are no interlock relationships as defined in the applicable SEC rules. Stockholder Return Performance Graph The following graph and table show the cumulative total stockholder return on Trex Company's common stock compared to the Russell 2000 Index and a self-constructed peer group index for the periods between April 8, 1999, the date the common stock began trading on the New York Stock Exchange, and December 31, 2001, the last trading day in fiscal 2001. The peer group index is composed of the following public companies: U.S. Plastic Lumber Corp. and Advanced Environmental Recycling Technologies, Inc., each of which markets non-wood decking alternative products; and Masco Corporation, Elcor Corporation, Restoration Hardware, Inc., American Woodmark Corporation and Ethan Allen Interiors Inc., each of which emphasizes product branding and engages in manufacturing and distribution of products to the building and consumer products industries. The graph assumes $100 was invested on April 8, 1999 in (1) Trex Company common stock, (2) the Russell 2000 Index and (3) the peer group index, and assumes reinvestment of dividends and market capitalization weighting as of April 8, 1999 and December 31, 1999, 2000 and 2001. 13

Representatives of Ernst & Young are expected to be present at the annual meeting and will be afforded the opportunity to make a statement, if they so desire, and to respond to appropriate questions. The following sets forth the aggregate fees billed to Trex Company for the fiscal year ended December 31, 2001 by Ernst &Young: Audit fees.......................... $123,000 Financial information systems design and implementation fees........... 0 All other fees...................... 184,000 -------- $307,000 ======== The amounts shown above include out-of-pocket expenses incurred by Ernst & Young in connection with the provision of such services. The audit committee of the board of directors considered whether Ernst & Young's provision of non-audit services is compatible with maintaining Ernst & Young's independence. 14

Report of the Audit Committee The audit committee reviews Trex Company's financial reporting process on behalf of the board of directors. In fulfilling its responsibilities, the committee has reviewed and discussed the audited financial statements contained in Trex Company's Annual Report on SEC Form 10-K for the year ended December 31, 2001 with Trex Company's management and the independent auditors. Management is responsible for the financial statements and the reporting process, including the system of internal controls. The independent auditors are responsible for expressing an opinion on the conformity of those audited financial statements with accounting principles generally accepted in the United States. The committee discussed with the independent auditors the matters required to be discussed by Statement on Auditing Standards No. 61, Communication with Audit Committees, as amended. In addition, the committee has discussed with the independent auditors the auditor's independence from Trex Company and its management, including the matters in the written disclosures required by Independence Standards Board Standard No. 1, Independence Discussions with Audit Committees. In reliance on the review and discussions referred to above, the committee recommended to the board of directors, and the board of directors has approved, the inclusion of the audited financial statements in Trex Company's Annual Report on SEC Form 10-K for the year ended December 31, 2001, for filing with the Securities and Exchange Commission. Respectfully submitted, THE AUDIT COMMITTEE William H. Martin, III (Chairman) William F. Andrews Patricia B. Robinson SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Section 16(a) of the Securities Exchange Act of 1934 requires Trex Company's directors and executive officers and persons who own more than 10% of a registered class of Trex Company's equity securities to file with the SEC and the New York Stock Exchange initial reports of ownership and reports of changes in ownership of common stock and other equity securities of Trex Company. The reporting persons are required by rules of the SEC to furnish Trex Company with copies of all Section 16(a) reports they file. Based solely upon a review of Section 16(a) reports furnished to Trex Company for fiscal 2001 or written representations that no other reports were required, Trex Company believes that the foregoing reporting persons complied with all filing requirements for fiscal 2001.
