TO EACH OF THE PURCHASERS LISTED IN
THE ATTACHED SCHEDULE A:

Ladies and Gentlemen:

     ELKCORP, a Delaware corporation (the “Company”), agrees with you as follows:

1. AUTHORIZATION OF NOTES.

     The Company has authorized the issue and sale of $50,000,000 aggregate principal amount of its 6.28% Senior Notes due November 15, 2014 (the “Notes”, such term to include any such Notes issued in substitution therefor pursuant to Section 13 of this Agreement). The Notes shall be substantially in the form set out in Exhibit 1(a) with such changes therefrom, if any, as may be approved by you, the Other Purchasers and the Company. Certain capitalized terms used in this Agreement are defined in Schedule B; references to a “Schedule” or an “Exhibit” are, unless otherwise specified, to a Schedule or an Exhibit attached to this Agreement. Subject to Section 22, the Notes will be guaranteed by each Restricted Subsidiary that as of the Closing is or in the future becomes a signatory to the Bank Guaranty or a borrower under the Credit Agreement (individually, a “Subsidiary Guarantor” and collectively, the “Subsidiary Guarantors”) pursuant to a guaranty in substantially the form of Exhibit 1(b) (the “Subsidiary Guaranty”). The Notes shall be unsecured and shall rank pari passu with the Company’s Debt to Banks under the Credit Agreement and with all other senior unsecured Debt of the Company.

2. SALE AND PURCHASE OF NOTES.

     Subject to the terms and conditions of this Agreement, the Company will issue and sell to you and each of the other purchasers named in Schedule A (the “Other Purchasers”), and you and the Other Purchasers will purchase from the Company, at the Closing provided for

in Section 3, Notes in the principal amount specified opposite your names in Schedule A at the purchase price of 100% of the principal amount thereof. Your obligation hereunder and the obligations of the Other Purchasers are several and not joint obligations and you shall have no liability to any Person for the performance or non-performance by any Other Purchaser hereunder.

3. CLOSING.

     The sale and purchase of the Notes to be purchased by you and the Other Purchasers shall occur at the offices of Gardner Carton & Douglas LLP, Suite 3700, 191 North Wacker Drive, Chicago, Illinois 60606 at 9:00 a.m., Chicago time, at a closing (the “Closing”) on November 15, 2004 or on such other Business Day thereafter on or prior to November 30, 2004 as may be agreed upon by the Company and you and the Other Purchasers. At the Closing the Company will deliver to you the Notes to be purchased by you in the form of a single Note (or such greater number of Notes in denominations of at least $100,000 as you may request) dated the date of the Closing and registered in your name (or in the name of your nominee), against delivery by you to the Company or its order of immediately available funds in the amount of the purchase price therefor by wire transfer of immediately available funds for the account of the Company to account number 1252603284 at Bank of America, 910 Main Street, Dallas, Texas 75202, ABA #111000012. If at the Closing the Company fails to tender such Notes to you as provided above in this Section 3, or any of the conditions specified in Section 4 shall not have been fulfilled to your satisfaction, you shall, at your election, be relieved of all further obligations under this Agreement, without thereby waiving any rights you may have by reason of such failure or such nonfulfillment.

4. CONDITIONS TO CLOSING.

     The Company is a corporation duly organized, validly existing and in good standing under the laws of its jurisdiction of incorporation, and is duly qualified as a foreign corporation and is in good standing in each jurisdiction in which such qualification is required by law, other than those jurisdictions as to which the failure to be so qualified or in good standing could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

4

proposes to transact, to execute and deliver this Agreement and the Notes and to perform the provisions hereof and thereof.

5.2. Authorization, etc.

     This Agreement and the Notes have been duly authorized by all necessary corporate action on the part of the Company, and this Agreement constitutes, and upon execution and delivery thereof each Note will constitute, a legal, valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except as such enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditors’ rights generally and (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

     The Subsidiary Guaranty at the time of Closing will have been duly authorized by all necessary corporate or partnership action on the part of each Subsidiary Guarantor and upon execution and delivery thereof will constitute the legal, valid and binding obligation of each Subsidiary Guarantor, enforceable against each Subsidiary Guarantor in accordance with its terms, except as such enforceability may be limited by (i) applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditors’ rights generally and (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

7

     violation, individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect.

     The Company and its Subsidiaries have filed all tax returns that are required to have been filed in any jurisdiction, and have paid all taxes shown to be due and payable on such returns and all other taxes and assessments levied upon them or their properties, assets, income or franchises, to the extent such taxes and assessments have become due and payable and before they have become delinquent, except for any taxes and assessments (i) the amount of which is not individually or in the aggregate Material or (ii) the amount, applicability or validity of which is currently being contested in good faith by appropriate proceedings and with respect to which the Company or a Subsidiary, as the case may be, has established adequate reserves in accordance with GAAP. The Company knows of no basis for any other tax or assessment that could reasonably be expected to have a Material Adverse Effect.

8

     (c) to the best knowledge of the Company, there is no Material violation by any Person of any right of the Company or any of its Subsidiaries with respect to any patent, copyright, service mark, trademark, trade name or other right owned or used by the Company or any of its Subsidiaries.

5.12. Compliance with ERISA.

     (a) The Company and each ERISA Affiliate have operated and administered each Plan in compliance with all applicable laws except for such instances of noncompliance as have not resulted in and could not reasonably be expected to result in a Material Adverse Effect. Neither the Company nor any ERISA Affiliate has incurred any liability pursuant to Title I or IV of ERISA or the penalty or excise tax provisions of the Code relating to employee benefit plans (as defined in Section 3 of ERISA), and no event, transaction or condition has occurred or exists that could reasonably be expected to result in the incurrence of any such liability by the Company or any ERISA Affiliate, or in the imposition of any Lien on any of the rights, properties or assets of the Company or any ERISA Affiliate, in either case pursuant to Title I or IV of ERISA or to such penalty or excise tax provisions or to Section 401(a)(29) or 412 of the Code, other than such liabilities or Liens as would not be individually or in the aggregate Material.

     (b) The present value of the aggregate benefit liabilities under each of the Plans (other than Multiemployer Plans), determined as of the end of such Plan’s most recently ended plan year on the basis of the actuarial assumptions specified for funding purposes in such Plan’s most recent actuarial valuation report, did not exceed the aggregate current value of the assets of such Plan allocable to such benefit liabilities.

     (e) The execution and delivery of this Agreement and the issuance and sale of the Notes hereunder will not involve any transaction that is subject to the prohibitions of section 406 of ERISA or in connection with which a tax could be imposed pursuant to section 4975(c)(1)(A)-(D) of the Code. The representation by the Company in the first sentence of this Section 5.12(e) is made in reliance upon and subject to the accuracy of your representation in Section 6.2 as to the sources of the funds used to pay the purchase price of the Notes to be purchased by you.

     Neither the Company nor anyone acting on its behalf has offered the Notes or any similar securities for sale to, or solicited any offer to buy any of the same from, or otherwise approached or negotiated in respect thereof with, any person other than you, the Other Purchasers and not more than four other Institutional Investors, each of which has been offered the Notes at a private sale for investment. Neither the Company nor anyone acting on its behalf has taken, or will take, any action that would subject the issuance or sale of the Notes to the registration requirements of Section 5 of the Securities Act.

5.14. Use of Proceeds; Margin Regulations.

     The Company will apply the proceeds of the sale of the Notes for general corporate purposes and to fund growth opportunities. No part of the proceeds from the sale of the Notes will be used, directly or indirectly, for the purpose of buying or carrying any margin stock within the meaning of Regulation U of the Board of Governors of the Federal Reserve System (12 CFR 221), or for the purpose of buying or carrying or trading in any securities under such circumstances as to involve the Company in a violation of Regulation X of said Board (12 CFR 224) or to involve any broker or dealer in a violation of Regulation T of said Board (12 CFR 220). Margin stock does not constitute more than 1% of the value of the consolidated assets of the Company and its Subsidiaries and the Company does not have any present intention that margin stock will constitute more than 1% of the value of such assets. As used in this Section, the terms “margin stock” and “purpose of buying or carrying” shall have the meanings assigned to them in said Regulation U.

5.15. Existing Debt; Future Liens.

     (a) Except as described therein, Schedule 5.15 sets forth a complete and correct list of all outstanding Debt of the Company and its Subsidiaries as of March 31, 2004, since which date there has been no Material change in the amounts, interest rates, sinking funds, installment payments or maturities of the Debt of the Company or its Subsidiaries. Neither the Company nor any Subsidiary is in default and no waiver of default is currently in effect, in the payment of any principal or interest on any Debt of the Company or such Subsidiary and no event or condition exists with respect to any Debt of the Company or any Subsidiary that would permit (or that with notice or the lapse of time, or both, would permit) one or more Persons to cause such Debt to become due and payable before its stated maturity or before its regularly scheduled dates of payment.

     (b) Except as disclosed in Schedule 5.15, neither the Company nor any Subsidiary has agreed or consented to cause or permit in the future (upon the happening of a contingency or otherwise) any of its property, whether now owned or hereafter acquired, to be subject to a Lien not permitted by Section 10.5.

10

5.16. Foreign Assets Control Regulations, Anti-Terrorism Order, etc.

     Neither the sale of the Notes by the Company hereunder nor its use of the proceeds thereof will violate (a) the Trading with the Enemy Act, as amended, (b) any of the foreign assets control regulations of the United States Treasury Department (31 CFR, Subtitle B, Chapter V, as amended) or any enabling legislation or executive order relating thereto or (c) to the knowledge of the Company, the Anti-Terrorism Order. Without limiting the foregoing, neither the Company nor any Subsidiary (i) is a blocked person described in Section 1 of the Anti-Terrorism Order or (ii) engages in any dealings or transactions, or is otherwise associated, with any such person.

5.17. Status under Certain Statutes.

     Neither the Company nor any Subsidiary is subject to regulation under the Investment Company Act of 1940, as amended, the Public Utility Holding Company Act of 1935, as amended, the Interstate Commerce Act, as amended by the ICC Termination Act, as amended, or the Federal Power Act, as amended.

Except as disclosed in Schedule 5.18,

     (a) neither the Company nor any Subsidiary has knowledge of any facts which would give rise to any claim, public or private, of violation of Environmental Laws or damage to the environment emanating from, occurring on or in any way related to real properties now or formerly owned, leased or operated by any of them or to other assets or their use, except, in each case, such as could not reasonably be expected to result in a Material Adverse Effect;

     (b) neither the Company nor any of its Subsidiaries has stored any Hazardous Materials on real properties now or formerly owned, leased or operated by any of them and has not disposed of any Hazardous Materials in a manner contrary to any Environmental Laws in each case in any manner that could reasonably be expected to result in a Material Adverse Effect; and

     (c) all buildings on all real properties now owned, leased or operated by the Company or any of its Subsidiaries are in compliance with applicable Environmental Laws, except where failure to comply could not reasonably be expected to result in a Material Adverse Effect.

You understand that the Notes have not been registered under the Securities Act and may be resold only if registered pursuant to the provisions of the Securities Act or if an exemption from registration is available, except under circumstances where neither such registration nor such an exemption is required by law, and that the Company is not required to register the Notes. You represent that you are an “accredited investor” within the meaning of subparagraph (a)(1), (2), (3) or (7) of Rule 501 of Regulation D under the Securities Act and you agree that any resale of Notes by you will comply with the preceding sentence.

12

8. PREPAYMENT OF THE NOTES.

8.1. No Scheduled Prepayments.

     No regularly scheduled prepayments are due on the Notes prior to their stated maturity.

8.2. Optional Prepayments with Make-Whole Amount.

     The Company may, at its option, upon notice as provided below, prepay at any time all, or from time to time any part of, the Notes in an amount not less than $1,000,000 in the aggregate in the case of a partial prepayment, at 100% of the principal amount so prepaid, plus the Make-Whole Amount determined for the prepayment date with respect to such principal amount. The Company will give each holder of Notes written notice of each optional prepayment under this Section 8.2 not less than 30 days and not more than 60 days prior to the date fixed for such prepayment. Each such notice shall specify such date, the aggregate principal amount of the Notes to be prepaid on such date, the principal amount of each Note held by such holder to be prepaid (determined in accordance with Section 8.3), and the interest to be paid on the prepayment date with respect to such principal amount being prepaid, and shall be accompanied by a certificate of a Senior Financial Officer as to the estimated Make-Whole Amount due in connection with such prepayment (calculated as if the date of such notice were the date of the prepayment), setting forth the details of such computation. Two Business Days prior to such prepayment, the Company shall deliver to each holder of Notes a certificate of a Senior Financial Officer specifying the calculation of such Make-Whole Amount as of the specified prepayment date.

8.3. Allocation of Partial Prepayments.

     In the case of each partial prepayment of the Notes pursuant to this Section 8, the principal amount of the Notes to be prepaid shall be allocated among all of the Notes at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal amounts thereof not theretofore called for prepayment.

8.4. Maturity; Surrender, etc.

     In the case of each prepayment of Notes pursuant to this Section 8, the principal amount of each Note to be prepaid shall mature and become due and payable on the date fixed for such prepayment, together with interest on such principal amount accrued to such date and the applicable Make-Whole Amount, if any. From and after such date, unless the Company shall fail to pay such principal amount when so due and payable, together with the interest and Make-Whole Amount, if any, as aforesaid, interest on such principal amount shall cease to accrue. Any Note paid or prepaid in full shall be surrendered to the Company and canceled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal amount of any Note.

18

8.5. Purchase of Notes.

     The Company will not and will not permit any Affiliate to purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding Notes except upon the payment or prepayment of the Notes in accordance with the terms of this Agreement and the Notes. The Company will promptly cancel all Notes acquired by it or any Affiliate pursuant to any payment, prepayment or purchase of Notes pursuant to any provision of this Agreement and no Notes may be issued in substitution or exchange for any such Notes.

8.6. Make-Whole Amount.

     The term “Make-Whole Amount” means, with respect to any Note, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such Note over the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the Make-Whole Amount, the following terms have the following meanings:

      “Called Principal” means, with respect to any Note, the principal of such Note that is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

      “Discounted Value” means, with respect to the Called Principal of any Note, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal.

      “Reinvestment Yield” means, with respect to the Called Principal of any Note, .50% over the yield to maturity implied by (i) the yields reported, as of 10:00 A.M. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as the “PX1 Screen” on the Bloomberg Financial Market Service (or such other display as may replace the PX1 Screen on Bloomberg Financial Market Service) for actively traded U.S. Treasury securities having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or (ii) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable, the Treasury Constant Maturity Series Yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (519) (or any comparable successor publication) for actively traded U.S. Treasury securities having a constant maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. Such implied yield will be determined, if necessary, by (a) converting U.S. Treasury bill quotations to bond-equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between (1) the actively traded U.S. Treasury security with the maturity closest to and greater than the Remaining

19

Average Life and (2) the actively traded U.S. Treasury security with the maturity closest to and less than the Remaining Average Life.

      “Remaining Average Life” means, with respect to any Called Principal, the number of years (calculated to the nearest one-twelfth year) obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years (calculated to the nearest one-twelfth year) that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment.

      “Remaining Scheduled Payments” means, with respect to the Called Principal of any Note, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a date on which interest payments are due to be made under the terms of the Notes, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Section 8.2 or 12.1.

      “Settlement Date” means, with respect to the Called Principal of any Note, the date on which such Called Principal is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

9. AFFIRMATIVE COVENANTS.

     The Company covenants that so long as any of the Notes are outstanding:

9.1. Compliance with Law.

     The Company will, and will cause each Subsidiary to, comply with all laws, ordinances or governmental rules or regulations to which each of them is subject, including, without limitation, Environmental Laws, and will obtain and maintain in effect all licenses, certificates, permits, franchises and other governmental authorizations necessary to the ownership of their respective properties or to the conduct of their respective businesses, in each case to the extent necessary to ensure that non-compliance with such laws, ordinances or governmental rules or regulations or failures to obtain or maintain in effect such licenses, certificates, permits, franchises and other governmental authorizations could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

9.2. Insurance.

     The Company will, and will cause each Restricted Subsidiary to, maintain, with financially sound and reputable insurers, insurance with respect to their respective properties and businesses against such casualties and contingencies, of such types, on such terms and in such amounts (including deductibles, co-insurance and self-insurance, if adequate reserves are

9.3. Maintenance of Properties.

     The Company will and will cause each Restricted Subsidiary to maintain and keep, or cause to be maintained and kept, their respective properties in good repair, working order and condition (other than ordinary wear and tear), so that the business carried on in connection therewith may be properly conducted at all times, provided that this Section shall not prevent the Company or any Restricted Subsidiary from discontinuing the operation and the maintenance of any of its properties if such discontinuance is desirable in the conduct of its business and the Company has concluded that such discontinuance could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

9.4. Payment of Taxes and Claims.

     The Company will, and will cause each Subsidiary to, file all income tax or similar tax returns required to be filed in any jurisdiction and to pay and discharge all taxes shown to be due and payable on such returns and all other taxes, assessments, governmental charges, or levies imposed on them or any of their properties, assets, income or franchises, to the extent such taxes and assessments have become due and payable and before they have become delinquent and all claims for which sums have become due and payable that have or might become a Lien on properties or assets of the Company or any Subsidiary, provided that neither the Company nor any Subsidiary need pay any such tax or assessment or claims if (i) the amount, applicability or validity thereof is contested by the Company or such Subsidiary on a timely basis in good faith and in appropriate proceedings, and the Company or a Subsidiary has established adequate reserves therefor in accordance with GAAP on the books of the Company or such Subsidiary or (ii) the nonpayment of all such taxes and assessments in the aggregate could not reasonably be expected to have a Material Adverse Effect.

9.5. Corporate Existence, etc.

     The Company will at all times preserve and keep in full force and effect its corporate existence.

10.4. Debt of Restricted Subsidiaries.

A failure by a holder of Notes to respond at least 10 days prior to the proposed prepayment date shall be deemed to constitute a rejection of such offer by such holder. If at the time of making such offer to prepay and following such prepayment there is no Debt of the Company or any Restricted Subsidiary outstanding other than the Notes, any net proceeds remaining unapplied shall not be subject to or included in the limitation and computation contained in Section 10.6(c)(ii).
