As previously reported by Trex Company, Inc. (the “Company”) in its Current Report on Form 8-K filed on July 26, 2007, Anthony J. Cavanna retired as Chief Executive Officer of the Company, effective August 15, 2007.

The amended awards will vest over the following vesting schedule instead of expiring on the date of Mr. Cavanna’s retirement as Chief Executive Officer, as provided in the original grant agreements, and all SARs must be exercised prior to ten years after the original grant date:

Compensation of Anthony J. Cavanna as Non-Employee Chairman of the Board. On August 14, 2007, pursuant to the Trex Company, Inc. Amended and Restated 1999 Incentive Plan for Outside Directors, the Board of Directors determined that Mr. Cavanna will receive compensation as non-employee Chairman of the Board in the form of an annual cash retainer of $54,000 payable in equal quarterly installments and pro-rated for any partial quarters of service. Instead of the annual equity grant awarded to other non-employee directors, Mr. Cavanna will receive an annual cash payment of $25,361 pro-rated based on his term of service and payable as of his last date of service as Chairman.

Compensation of Andrew U. Ferrari as Chief Executive Officer. As previously reported by the Company in its Current Report on Form 8-K filed on July 26, 2007, the Board of Directors appointed Andrew U. Ferrari, the President and Chief Operating Officer and a member of the Board of Directors, as Chief Executive Officer, effective as of Mr. Cavanna’s retirement on August 15, 2007.

On August 14, 2007, pursuant to the Company’s annual executive compensation program (the “Program”), the Compensation Committee determined that Mr. Ferrari’s base salary will be payable at the increased annual rate of $500,000.

Under the Program, the Company pays annual cash bonuses based upon the achievement of specified performance objectives. For each fiscal year, each participant in the Program is assigned a “target bonus,” which is expressed as a percentage of the participant’s annual base salary or salary range midpoint for such fiscal year, depending on grade level. The bonus percentage levels for each fiscal year and the performance objectives are annually approved by the Compensation Committee. On August 14, 2007, pursuant to the Program, the Compensation Committee assigned Mr. Ferrari a “target bonus” of 80% for 2007.

Under the Program, the Company grants annual long-term equity grant incentives based upon each executive officer’s current performance and anticipated future contribution to the Company’s results. For each fiscal year, each participant in the Program is assigned a “target long-term incentive,” which is expressed as a percentage of the participant’s annual base salary or salary range midpoint for such fiscal year, depending on grade. On August 14, 2007, pursuant to the Program, the Compensation Committee assigned Mr. Ferrari a “target long-term incentive” of 220% for future grants.
