PERFORMANCE STOCK AWARD AGREEMENT

This Performance Stock Award Agreement (“Agreement”) entered into as of the 26th day of October, 2004 (the “Date of Grant”) between ElkCorp, a Delaware corporation (hereinafter called the “Company”), and [Name] , an employee of the Company or an Affiliated Entity (as defined in Section 10) of the Company (hereinafter called the “Employee”).

WHEREAS, the Company has made this day, pursuant to the 2004 Amended and Restated ElkCorp Equity Incentive Compensation Plan (the “Plan”), a Performance Stock Award (as defined in the Plan) on the terms and subject to the performance and other conditions described herein; and

WHEREAS, the Company wishes to document such award with an Award Agreement (as defined in the Plan);

NOW, THEREFORE, in consideration of the mutual covenants herein contained, the parties hereto agree as follows:

1. PERFORMANCE STOCK AWARD.

(a) General. The Company hereby awards and grants to the Employee a Performance Stock Award consisting of a contingent right to receive whole shares of the common stock, $1 par value per share, of the Company (“Common Stock”), on the terms and conditions hereinafter set forth and otherwise subject to the terms and conditions of the Plan. Such shares are not issued and are completely unvested and forfeitable as of the Date of Grant. The shares shall be issued and shall vest and become nonforfeitable only upon the Company’s achieving the performance criteria set forth below, unless otherwise forfeited under the other provisions of this Agreement. The shares that Employee shall be entitled to receive if the Company achieves Target ROE Performance (“ROE Target Award”) shall be shares of Common Stock, and the shares that Employee shall be entitled to receive if the Company achieves Target TSR Performance (“TSR Target Award”) shall be shares of Common Stock, subject to increase, decrease or forfeiture in accordance with this Agreement, including without limitation the provisions of Section 1(b) through 1(f).

(b) Award Subject to Return on Equity Performance Conditions. For the three-year performance cycle beginning July 1, 2004, and ending at the close of business on June 30, 2007 (the “ROE Performance Cycle”), Employee will be entitled to receive shares of Common Stock (the “ROE Performance Stock”) if and when the Company achieves Actual ROE Performance (defined below) equal to or greater than Threshold ROE Performance (defined below). Subject to Section 1(e), the ROE Performance Stock, to the extent if any earned under the terms and conditions of this Agreement, shall be issued promptly following the completion of the independent audit(s) of the Company’s financial statements for the last fiscal period in the ROE Performance Cycle, and the Administering Body’s certification that the applicable performance criteria for such award have been met (based on the results of such audit(s)), but not later than 75

days after the end of the ROE Performance Cycle unless more time is administratively required due to a delay in the completion of such audit(s).

(i) Number of Shares of ROE Performance Stock to be Issued. The number of shares of ROE Performance Stock that Employee will earn under this Agreement will range from none to 150 percent of the ROE Target Award, depending on the performance of the Company, as follows:

(A) If the Company’s Actual ROE Performance is less than Threshold ROE Performance, then no ROE Performance Stock will be issued to Employee under this Agreement.

(B) If the Company’s Actual ROE Performance is equal to Target ROE Performance (defined below), then the Company will issue to Employee that number of shares of ROE Performance Stock equal to the ROE Target Award.

(C) If the Company’s Actual ROE Performance is equal to or better than Maximum ROE Performance (defined below), Company will issue to Employee that number of shares of ROE Performance Stock equal to the ROE Target Award times 150 percent.

(D) If the Company’s Actual ROE Performance is greater than Threshold ROE Performance but less than Target ROE Performance, the Company will issue to Employee that number of shares of ROE Performance Stock equal to the ROE Target Award times a fraction, the numerator of which is the Company’s Actual ROE Performance minus Threshold ROE Performance, and the denominator of which is Target ROE Performance minus Threshold ROE Performance.

(E) If the Company’s Actual ROE Performance is greater than Target ROE Performance but less than Maximum ROE Performance (defined below), the Company will issue that number of shares of ROE Performance Stock equal to the ROE Target Award times the sum of (I) one plus (II) one-half times a fraction, the numerator of which is the Company’s Actual ROE Performance minus Target ROE Performance, and the denominator of which is Maximum ROE Performance minus Target ROE Performance.

(ii) Definitions and Performance Criteria for ROE Performance Stock. For purposes of this Section 1(b), the following defined terms will have the meanings ascribed to them below:

(A) “Actual ROE Performance” means the arithmetic average of the Company’s actual return on beginning equity for its three fiscal years in the ROE Performance Cycle, as calculated based on financial performance confirmed by the Company’s independent auditors for each year in the ROE Performance Cycle.

(B) “Maximum ROE Performance” means the arithmetic average return on beginning equity for the three complete fiscal years immediately preceding the ROE Performance Cycle determined for each year as the level equal to the 84^th percentile of all New

- 2 -

York Stock Exchange (“NYSE”) listed companies, as conclusively determined in the database furnished to the Administering Body by its independent compensation consultants, which the parties acknowledge and agree is 24.5 percent.

(C) “Target ROE Performance” means the arithmetic average return on beginning equity for the three complete fiscal years immediately preceding the ROE Performance Cycle determined for each year at a level equal to the 62nd percentile of all NYSE-listed companies, as conclusively determined in the database furnished to the Administering Body by independent compensation consultants, which the parties acknowledge and agree is 13.8 percent.

(D) “Threshold ROE Performance” means the arithmetic average return on beginning equity for the three complete fiscal years immediately preceding the ROE Performance Cycle determined for each year at a level equal to the 50^th percentile of all NYSE-listed companies, as conclusively determined in the database furnished to the Administering Body by independent compensation consultants, which the parties acknowledge and agree is 10.4 percent.

(iii) ROE Performance Stock Independently Determined; Rounding. Amounts of ROE Performance Stock to be calculated and awarded under this Agreement will be calculated and made without regard to whether or how much TSR Performance Stock is calculated and awarded under this Agreement. If a calculation of ROE Performance Stock to be awarded results in a fractional number of shares, the number of shares to be issued to Employee shall be rounded up to the nearest whole number of shares.

(iv) ROE Performance Stock – Example. Executive A receives a ROE Target Award of 200 shares. Over the three complete fiscal years preceding the ROE Performance Cycle, the 50^th percentile level of ROE Performance for NYSE-listed companies (Threshold ROE Performance) is 10.4 percent, the 62^nd percentile (Target ROE Performance) is 13.8 percent and the 84^th percentile (Maximum ROE Performance) is 24.5 percent. If ElkCorp’s Actual ROE Performance is 12.0 percent, then Executive A will be entitled to a payout of ROE Performance Stock at the end of the ROE Performance Cycle of 95 shares of ElkCorp Common Stock (200 shares X (12.0 – 10.4) ÷ (13.8 – 10.4)). If ElkCorp’s Actual ROE Performance is 16.7 percent, then Executive A will be entitled to a payout of ROE Performance Stock at the end of the ROE Performance Cycle of 228 shares of ElkCorp Common Stock (200 shares X (1 + ((16.7 – 13.8) ÷ (24.5 – 13.8) X 0.50)). The ROE Performance Stock is issued to Executive A whether or not TSR Performance Stock is earned or issued.

(c) Award Subject to Total Shareholder Return Performance Conditions. For the three-year performance cycle beginning July 1, 2004, and ending at the close of business on June 30, 2007 (the “TSR Performance Cycle”), Employee will be entitled to receive shares of Common Stock (the “TSR Performance Stock”) if and when the Company achieves Actual TSR Performance (defined below) over the TSR Performance Cycle equal to or greater than Threshold TSR Performance (defined below). Subject to Section 1(e), the TSR Performance Stock, to the extent if any earned under the terms and conditions of this Agreement, shall be issued promptly following the Administering Body’s certification that the applicable

- 3 -

performance criteria for such award have been met, but in no event later than 75 days after the end of the TSR Performance Cycle.

(i) Number of Shares of TSR Performance Stock to be Issued. The number of shares of TSR Performance Stock that Employee will earn under this Agreement will range from none to 150 percent of the TSR Target Award, depending on the performance of the Company, as follows:

(A) If the Company’s Actual TSR Performance is less than Threshold TSR Performance, then no TSR Performance Stock will be issued to Employee under this Agreement.

(B) If the Company’s Actual TSR Performance is equal to Target TSR Performance (defined below), then the Company will issue to Employee that number of shares of TSR Performance Stock equal to the TSR Target Award.

(C) If the Company’s Actual TSR Performance is equal to or better than Maximum TSR Performance (defined below), Company will issue to Employee that number of shares of TSR Performance Stock equal to the TSR Target Award times 150 percent.

(D) If the Company’s Actual TSR Performance is greater than Threshold TSR Performance but less than Target TSR Performance, the Company will issue to Employee that number of shares of TSR Performance Stock equal to the TSR Target Award times a fraction, the numerator of which is the Company’s Actual TSR Performance minus Threshold TSR Performance, and the denominator of which is Target TSR Performance minus Threshold TSR Performance.

(E) If the Company’s Actual TSR Performance is greater than Target TSR Performance but less than Maximum TSR Performance (defined below), the Company will issue that number of shares of TSR Performance Stock equal to the TSR Target Award times the sum of (I) one plus (II) one-half times a fraction, the numerator of which is the Company’s Actual TSR Performance minus Target TSR Performance, and the denominator of which is Maximum TSR Performance minus Target TSR Performance.

(ii) Definitions and Performance Criteria for TSR Performance Stock. For purposes of this Section 1(c), the following defined terms will have the meanings ascribed to them below:

(A) “Actual TSR Performance” means the total value, at the closing price on the NYSE on the last business day of the TSR Performance Cycle, of a hypothetical $100.00 investment in the Company’s Common Stock, assuming immediate reinvestment of all dividends paid, and assuming initial purchase at the opening price on the NYSE on the first business day of the TSR Performance Cycle, as such total value is confirmed by the Administering Body.

- 4 -

(B) “Maximum TSR Performance” means the total value at a level equal to the eighty-fourth (84^th) percentile of all NYSE-listed companies, at the closing price on the NYSE on the last business day of the TSR Performance Cycle, of a hypothetical $100.00 investment in their respective listed stock(s), assuming immediate reinvestment of all dividends paid, and assuming initial purchase at the opening price on the NYSE on the first business day of the TSR Performance Cycle, as such total value is conclusively determined in the database furnished to the Administering Body by independent compensation consultants.

(C) “Target TSR Performance” means the total value at a level equal to the sixty-second (62^nd) percentile of all NYSE-listed companies, at the closing price on the NYSE on the last business day of the TSR Performance Cycle, of a hypothetical $100.00 investment in their respective listed stock(s), assuming immediate reinvestment of all dividends paid, and assuming initial purchase at the opening price on the NYSE on the first business day of the TSR Performance Cycle, as such total value is conclusively determined in the database furnished to the Administering Body by independent compensation consultants.

(D) “Threshold TSR Performance” means the total value at a level equal to the fiftieth (50^th) percentile of all NYSE-listed companies, at the closing price on the NYSE on the last business day of the TSR Performance Cycle, of a hypothetical $100.00 investment in their respective listed stock(s), assuming immediate reinvestment of all dividends paid, and assuming initial purchase at the opening price on the NYSE on the first business day of the TSR Performance Cycle, as such total value is conclusively determined in the database furnished to the Administering Body by independent compensation consultants.

(iii) TSR Performance Stock Independently Determined; Rounding. Amounts of TSR Performance Stock to be calculated and awarded under this Agreement will be calculated and made without regard to whether or how much ROE Performance Stock is calculated and awarded under this Agreement. If a calculation of TSR Performance Stock to be awarded results in a fractional number of shares, the number of shares to be issued to Employee shall be rounded up to the nearest whole number of shares.

(iv) TSR Performance Stock – Example. Executive A receives a TSR Target Award of 100 shares. Over the TSR Performance Cycle, the 50^th percentile level of TSR Performance for NYSE-listed companies (Threshold TSR Performance) is $138.50, the 62^nd percentile (Target TSR Performance) is $171.00, and the 84^th percentile (Maximum TSR Performance) is $225.00. If ElkCorp’s Actual TSR Performance is $155.00, then Executive A will be entitled to a payout of TSR Performance Stock at the end of the TSR Performance Cycle of 51 shares of ElkCorp Common Stock (100 shares X (155.00 – 138.50) ÷ (171.00 – 138.50)). If ElkCorp’s Actual TSR Performance is $206.21, then Executive A will be entitled to a payout of TSR Performance Stock at the end of the TSR Performance Cycle of 133 shares of ElkCorp Common Stock (100 shares X (1 + ((206.21 – 171.00) ÷ (225.00 – 171.00) X 0.50))). The TSR Performance Stock is issued to Executive A whether or not ROE Performance Stock is earned or issued.

- 5 -

Cycle or TSR Performance Cycle by reason of Employee’s Disability (as defined in Section 10), death or Retirement (as defined in Section 10), then the Employee, or Employee’s estate or personal representative, as the case may be, shall be entitled to the full number of shares of ROE Performance Stock and TSR Performance Stock to which Employee would have been entitled under the terms of this Agreement had Employee remained employed by the Company or its Affiliated Entity through the date that such awards are to be made under such terms.

(e) Change of Control. If there is a Change of Control (as defined in Section 10) of the Company after April 26, 2004, but prior to the last day of the ROE Performance Cycle or TSR Performance Cycle, then Employee shall nonetheless be entitled to the full number of ROE Performance Shares and TSR Performance Shares to which Employee would have been entitled had the Company achieved Maximum ROE Performance and Maximum TSR Performance, with all of such shares being awarded to and registered in the name of Employee immediately prior to the effective time of the Change of Control.

(f) Other Termination of Employment. Subject in all respects to Section 1(e), if Employee’s employment with the Company and all Affiliated Entities terminates prior to June 30, 2007 for any reason other than Employee’s Disability, death or Retirement, then all rights to receive shares of Performance Stock hereunder shall be forfeited and shall revert to the Company.

2. ISSUANCE OF PERFORMANCE STOCK.

(a) Upon the issuance of any shares granted hereunder, such shares shall be fully vested and nonforfeitable and the Employee shall become the owner of the shares free of all restrictions set forth in this Agreement, other than restrictions under applicable securities laws and affiliate stop transfer orders.

(b) To effect the issuance of ROE Performance Stock and TSR Performance Stock as provided in Section 1, the Employee shall be issued a stock certificate or certificates registered in the name of the Employee evidencing the shares of Common Stock to which the Employee is entitled under this Agreement, free of all restrictions set forth in this Agreement; however, such shares shall be subject to restrictions under applicable security laws and affiliate stop transfer orders.

Any attempted disposition of any of such shares or any interest therein shall be null and void and of no effect.

5. ADJUSTMENT PROVISIONS.

If prior to the end of the ROE Performance Cycle or TSR Performance Cycle, as applicable, (i) the outstanding shares of Common Stock of the Company are increased, decreased or exchanged for a different number or kind of shares or other securities, or if additional shares or new or different shares or other securities are distributed in respect of such shares of Common Stock (or any stock or securities received with respect to such Common Stock), through merger, consolidation, sale or exchange of all or substantially all of the assets of the Company, reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split, spin-off, split-off, split-up or other distribution with respect to such shares of Common Stock (or any stock or securities received with respect to such Common Stock), or (ii) the value of the outstanding shares of Common Stock is reduced by reason of an extraordinary dividend payable in cash or property, an appropriate and proportionate adjustment shall be made in the number of shares set forth as the ROE Target Award and TSR Target Award under this Agreement.

Any adjustment pursuant to this Section 5 shall be made by the Administering Body, in its discretion, to preserve the benefits or potential benefits of any shares subject to issuance hereunder or that may be otherwise necessary to reflect any capital change or other event described above in this Section 5. The determination made by the Administering Body with respect to any such adjustment shall be final, binding and conclusive upon all persons and entities.

6. INVESTMENT REPRESENTATIONS.

At the time of the issuance of any shares awarded under this Agreement, the Employee may, as a condition of the issuance of such shares and the receipt of certificates therefor, be required by the Company to furnish a representation that the Employee is acquiring the shares as an investment and not with a view to distribution if the Company, in its sole discretion, determines that such representation is required to ensure that the sale or resale or other disposition of the shares will not involve the violation of the Securities Act or any other applicable laws. The Company reserves the right to place any legend or other symbol on certificates for shares delivered pursuant to this Agreement and to issue any “stop transfer” or similar instructions to the transfer agent which the Company, in its sole discretion, deems necessary and proper to assure compliance with (a) any such representation or (b) any federal or state law.
