Re: Acquisition Financing—Senior Secured Financing Commitment Letter

Ladies and Gentlemen:

        You have informed Deutsche Bank AG New York Branch ("DBNY"), Deutsche Bank Securities Inc. ("DBSI" and, together with DBNY, "DB"), Bear, Stearns & Co. Inc. ("Bear Stearns") and Bear Stearns Corporate Lending Inc. ("BSCL" and together with DB and Bear Stearns, collectively, the "Committing Parties") that Building Materials Corporation of America ("you" or the "Company") intends to (i) acquire, directly or indirectly through one or more of its subsidiaries, ElkCorp ("Elk" and such acquisition being the "Acquisition"), and (ii) concurrently with the consummation of the Acquisition, refinance substantially all of your existing indebtedness (excluding the 7.75% Notes due 2014 (the "2014 Notes"), which will be equally and ratably secured with the Term Loan Facility (as defined below), and the existing indebtedness of Elk (collectively, the "Refinancing"). We understand that you desire to establish a senior secured credit facility in an aggregate principal amount of $1,550 million (the "Senior Secured Financing") the proceeds of which will be used (x) for the purchase price to be paid to effect the Acquisition, (y) to effect the Refinancing and (z) to pay fees and expenses payable in connection with the Transaction (as defined below). We further understand that Elk shall be acquired free of indebtedness and preferred stock, with such exceptions (if any) for any existing indebtedness as agreed to by the Lead Arrangers (as defined below).

        The sources of funds needed to effect the Acquisition and the Refinancing, to pay all fees and expenses incurred in connection with the Transaction and to provide for the working capital needs and general corporate requirements of you and your subsidiaries after giving effect to the Acquisition shall be provided solely through (i) a bridge financing or by the issuance by you (either pursuant to private placement or underwritten public sale) of senior secured notes (the "Senior Secured Notes") which shall generate $275 million^* of gross cash proceeds (calculated before underwriting fees) and (ii) the Senior Secured Financing (with the transactions described in preceding clauses (i) and (ii) being herein collectively referred to as the "Financing Transactions" and, together with the Acquisition and the Refinancing, being herein collectively referred to as the "Transaction").

*

The principal amount of the Senior Secured Notes will be reduced by the amount of your 8% Notes due 2007 and 2008 which are not retired or defeased as part of the Transaction, provided that in no event will the amount of the Senior Secured Notes be less than $150 million.

        We understand that the Senior Secured Financing shall consist of (i) up to an $850 million term loan facility (the "Term Loan Facility") and (ii) a $700 million revolving credit facility (the "Revolving Credit Facility" and, together with the Term Loan Facility, the "Credit Facilities"); it being understood that not more than $250 million (plus seasonal working capital requirements) or such greater amount as may be mutually agreed of the proceeds of the Revolving Credit Facility may be utilized to make payments owing to effect the Acquisition or the Refinancing or to pay any fees and expenses incurred in connection with the Transaction. Any commitments under the Term Loan Facility not required to

finance the Transaction will terminate on the date of the consummation of the Acquisition (the "Closing Date"). A summary of certain of the terms and conditions of the Revolving Credit Facility and Term Loan Facility is set forth in Exhibit A attached hereto (the "Term Sheet").

        Subject to the terms and conditions set forth herein and in the Term Sheet, (a) DBNY is pleased to confirm (i) its several and not joint commitment to provide 60% of each Credit Facility and (ii) its agreement to act as sole administrative agent (in such capacity, the "Administrative Agent") for a syndicate of lenders who will participate in the Senior Secured Financing (together with DBNY and BSCL, the "Lenders"), (b) BSCL is pleased to confirm its several and not joint commitment to provide 40% of each Credit Facility, (c) DBSI is pleased to confirm its agreement to act as a Joint Lead Arranger and Joint Book Running Manager for the Senior Secured Financing and (d) Bear Stearns is pleased to confirm its agreement to act as a Joint Lead Arranger and Joint Book Running Manager for the Senior Secured Financing. One other institution may also be designated as "Joint Lead Arranger" for each of the Credit Facilities, and one or more other institutions may be designated as "Joint Book Running Manager", "Syndication Agent", "Documentation Agent" or such other titles as may be deemed appropriate or desirable in connection with the syndication of the Senior Secured Financing (each of which shall participate appropriately in the Credit Facilities), DBSI and Bear Stearns, as Joint Lead Arrangers, and any such other Joint Lead Arranger are referred to herein as the "Lead Arrangers". It being understood and agreed that the DBSI name shall appear immediately to the left of Bear Stearns or any other arranger or manager and that the Bear Stearns name shall appear immediately above or immediately to the left of any other arranger or syndication agent (other than DBSI and, except with respect to the Revolving Credit Facility, such other "Joint Lead Arranger" as the Borrower may designate). You have informed us that you may decide to acquire Elk through a tender offer for the common shares of Elk and a subsequent merger. If you decide to proceed with such a tender offer and merger, we have agreed that our commitments herein would be applicable to such transaction with changes to the terms thereof as are customary for such transactions and mutually agreed.

        DBNY and BSCL (collectively, the "Initial Lenders") reserve the right, prior to or after execution of the definitive credit documentation for the Senior Secured Financing (the "Operative Documents") to syndicate all or part of their respective commitments hereunder to one or more other Lenders reasonably acceptable to you that will become party to such definitive credit documentation pursuant to a syndication to be managed by the Lead Arrangers in consultation with you. You agree that, upon delivery to the Lead Arrangers of a commitment letter addressed to the Company for all or a portion of the Senior Secured Financing containing terms not less favorable in any material respect to the Company than the terms hereof by a Lender that you have introduced to the Lead Arrangers as a potential Lender, the Initial Lenders shall be proportionally relieved of their respective obligations hereunder based on their relative commitments hereunder to the extent of such Lender's commitments set forth in such commitment letter. Furthermore, all aspects of the syndication of the Senior Secured Financing, including, without limitation, timing, potential syndicate members to be approached, titles, allocations and division of fees, shall be determined by the Lead Arrangers in consultation with you. You agree to actively assist the Lead Arrangers in forming a syndicate acceptable to the Lead Arrangers and you, including by using your commercially reasonable efforts to ensure that the Lead Arrangers' syndication efforts benefit materially from your existing lending relationships, and to provide the Lead Arrangers and the Lenders, upon reasonable request, with all information reasonably deemed necessary by the Lead Arrangers to complete successfully the syndication, including, but not limited to, (a) to the Lead Arrangers not less than 21 days prior to the funding of the Credit Facilities a confidential information memorandum for the Credit Facilities and (b) projections and other information prepared by you or your affiliates or advisors relating to the Transaction. You also agree (i) to make available your senior management and appropriate representatives to participate in information meetings with ratings agencies identified by Lead Arrangers and potential Lenders, in each case at such times and places as the Lead Arrangers may reasonably request, and (ii) at the request of

2

the Lead Arrangers, to assist in the preparation of a version of a confidential information memorandum to be used in connection with the syndication of the Senior Secured Financing, consisting exclusively of information and documentation that is either (i) publicly available with respect to the Borrower, Elk or their respective subsidiaries or (ii) not material with respect to the Borrower and its subsidiaries or any of their respective securities for purposes of United States Federal and state securities laws (all such information and documentation being "Public Information"). Any information and documentation that is not Public Information is referred to herein as "Private Information". You further agree that each document to be disseminated by the Administrative Agent to any Lender in connection with the Credit Facilities will be identified by you as either (i) containing Private Information or (ii) containing solely Public Information. The provisions of the fourth sentence and clause (ii) of the fifth sentence of this paragraph shall remain in full force and effect until the successful syndication of the Senior Secured Financing (as reasonably determined by the Lead Arrangers).

        You represent, warrant and covenant that (i) no written information, other than business and financial projections, budgets, pro forma data and forecasts, that has been or is hereafter furnished by you or on your behalf to the Lead Arrangers, any Lender or any prospective Lender in connection with the Transaction and (ii) no other information given at information meetings for potential syndicate members and supplied or approved by you or on your behalf (such written information and other information being referred to herein collectively as the "Information") taken as a whole contained (or, in the case of Information furnished after the date hereof, will contain), as of the time it was (or hereafter is) furnished, any material misstatement of fact or omitted (or will omit) as of such time to state any material fact necessary to make the statements therein taken as a whole not misleading, in the light of the circumstances under which they were (or hereafter are) made; provided, however, that, with respect to Elk and its subsidiaries, the foregoing representation is limited to your best knowledge. With respect to business and financial projections, budgets, pro forma data and forecasts, if any (collectively, the "Projections"), that have been or will be prepared by you or on your behalf and has been or is hereafter furnished by you or on your behalf to the Lead Arranger, any Lender or any prospective Lender in connection with Transaction, no representation, warranty or covenant is made other than that the Projections have been (and, in the case of Projections furnished after the date hereof, will be) prepared in good faith based on assumptions believed to be reasonable at the time of preparation thereof (it being understood that such Projections are subject to significant uncertainties and contingencies, many of which are beyond the Company's control, and that no assurance can be given that the Projections will be realized). You agree to supplement the Information and the Projections from time to time until the date of the initial borrowing under the Senior Secured Financing, as appropriate, so that the representations and warranties in the preceding sentence remain correct. You understand that, in syndicating the Senior Secured Financing, the Lead Arranger will use and rely on the Information and the Projections without independent verification thereof.

        The Committing Parities' commitments and other agreements hereunder are subject to (a) there not occurring any condition or circumstance which has had, or would reasonably be expected to have, a Material Adverse Effect (as defined below), (b) the accuracy and completeness in all material respects of the representations that the Company makes to Lead Arrangers and the Lenders pursuant to the immediately preceding paragraph, (c) the Company's compliance with the terms of this Commitment Letter (as defined below), and (d) the Lead Arrangers' reasonable satisfaction that prior to the earlier of (i) four months after the date on which the Operative Documents shall become effective and (ii) a Successful Syndication (as defined in the fee letter agreement dated the date hereof among the parties hereto, the "Fee Letter") there shall be no offering, placement or arrangement by you or on your behalf of any debt securities or bank financing (including refinancings and renewals of debt, but excluding the Senior Secured Notes and any ordinary course financing or refinancing of equipment purchases or leases) and (e) the other conditions referred to in the Term Sheet.

3

        "Material Adverse Effect" means any change, circumstance, event or effect since December 31, 2005 in the case of the Company and its Subsidiaries and June 30, 2006 in the case of Elk and its Subsidiaries that is materially adverse to the business, operations, financial condition or results of operations of the Company and its subsidiaries and Elk and its subsidiaries, taken as a whole, provided, however, that none of the following shall be deemed, either alone, or in combination, to constitute a Material Adverse Effect: any change, circumstance, event or effect resulting from or arising out of (a) the public announcement of the Acquisition or the Transaction, (b) general economic conditions, including prevailing interest rates, (c) general conditions in the industry in which the Company and Elk are conducting their business, or (d) any natural disaster or any act of terrorism, sabotage, military action or war (whether or not declared) or any escalation or worsening thereof unless, in the case of the foregoing clauses (b), (c) and (d), such changes, circumstances, events or effects referred to therein materially disproportionately impact the business conducted by the Company and Elk relative to the industry in which the Company and Elk compete as a whole.

        To induce the Committing Parties to issue this letter (together with the Term Sheet, this "Commitment Letter") and to proceed with the documentation of the Senior Secured Financing, you hereby agree that all fees and expenses (including the reasonable fees and expenses of counsel and consultants) of the Committing Parties and their respective affiliates arising in connection with this Commitment Letter and in connection with the Transaction and other transactions described herein (including in connection with our due diligence and syndication efforts) shall be for your account, whether or not the Transaction is consummated or the Senior Secured Financing is made available or the Operative Documents are executed. You further agree to indemnify and hold harmless the Administrative Agent, each Lead Arranger, and each other agent or co agent (if any) designated by the Committing Parties with respect to the Senior Secured Financing (each, an "Agent"), each Lender (including in any event each Initial Lenders) and their respective affiliates and each director, officer, employee, representative and agent thereof (each, an "Indemnified Person") from and against any and all actions, suits, proceedings (including any investigations or inquiries), claims, losses, damages, liabilities or expenses of any kind or nature whatsoever which may be incurred by or asserted against or involve any Agent, any Lender or any other such Indemnified Person as a result of or arising out of or in any way related to or resulting from the Transaction or this Commitment Letter and, upon demand, to pay and reimburse each Agent, each Lender and each other Indemnified Person for any reasonable legal or other out of pocket expenses paid or incurred in connection with investigating, defending or preparing to defend any such action, suit, proceeding (including any inquiry or investigation) or claim (whether or not any Agent, any Lender or any other such Indemnified Person is a party to any action or proceeding out of which any such expenses arise); provided, however, that you shall not have to indemnify any Indemnified Person against any loss, claim, damage, expense or liability to the extent same resulted from the gross negligence or willful misconduct of the respective Indemnified Person (as determined in a proceeding of a court of competent jurisdiction). Neither the Committing Parties nor any other Indemnified Person shall be responsible or liable to you or any other person or entity for (x) any determination made by it pursuant to this Commitment Letter in the absence of gross negligence or willful misconduct on the part of such person or entity (as determined in a proceeding of a court of competent jurisdiction), (y) any damages arising from the use by others of information or other materials obtained through electronic, telecommunications or other information transmission systems or (z) any indirect, special, incidental, punitive or consequential damages (including, without limitation, any loss of profits, business or anticipated savings) which may be alleged as a result of this Commitment Letter or the financing contemplated hereby.

	Interest in respect of Base Rate Loans shall be payable quarterly in arrears on the last business day of each calendar quarter. Interest in respect of Eurodollar Loans shall be payable in arrears at the end of the applicable interest period and every three months in the case of interest periods in excess of three months. Interest will also be payable at the time of repayment of any Loans and at maturity. All interest on Base Rate Loans, Eurodollar Loans and commitment fees and any other fees shall be based on a 360 day year and actual days elapsed (or, in the case of Base Rate Loans determined by reference to the prime lending rate, a 365/366 day year and actual days elapsed).

The Senior Secured Financing shall provide for a mechanism which will allow for each assignee to become a direct signatory to the Senior Secured Financing and will relieve the assigning Lender of its obligations with respect to the assigned portion of its commitment. Except during the continuance of a Default, the consent of the Borrower will be required for an assignment, which consent will not be unreasonably withheld.

Waivers and Amendments:

Amendments and waivers of the provisions of the loan documentation will require the approval of Lenders holding commitments and/or outstandings (as appropriate) representing more than 50% of the aggregate commitments and outstandings under the Term Loan Facility or the Revolving Credit Facility, as the case may be (the "Required Lenders"), except that (a) the consent of each Lender affected thereby will be required with respect to (i) increases in commitment amounts, (ii) reductions of principal, interest or fees and (iii) extensions of final scheduled maturities or times for payment of interest or fees, (b) the consent of all of the Lenders shall be required with respect to releases of all or substantially all of the collateral, and (c) the approval of Lenders holding commitments representing more than 66?% of the aggregate commitments under the Revolving Credit Facility will be required with respect to any changes to the Borrowing Base (or the definitions therein) which would result in an increase in availability thereunder; provided, however, that if any of the matters described in clause (a) or (b) above is agreed to by the Required Lenders, the Borrower shall have the right to either (x) substitute any non consenting Lender by having its Loans and commitments assigned, at par, to one or more other institutions, subject to the assignment provisions described above, or (y) with the consent of the Required Lenders, terminate the commitment of any non consenting Lender, subject to repayment in full of all obligations of the Borrower owed to such Lender relating to the Loans and participations held by such Lender.
