Items to be Included in this Report

Item 1.01. Entry into a Material Definitive Agreement.

On February 20, 2007, Owens Corning and Saint-Gobain announced that they have entered into agreements to form a global joint venture to develop, manufacture, market, sell and distribute glass reinforcements products. The new entity will be called OCV Reinforcements S.P.R.L.

Pursuant to the terms of a Master Contribution Agreement, each of Owens Corning and Saint-Gobain are contributing to the joint venture their worldwide glass reinforcements businesses, including plant, property and equipment, working capital, contractual arrangements, customers and intellectual property. In exchange for their contributions, Owens Corning will receive 60% of the voting and economic interests in the joint venture and Saint-Gobain will receive 40% of the voting and economic interests in the joint venture. The joint venture will be consolidated on the financial statements of Owens Corning.

Pursuant to the terms of a Joint Venture Agreement, the joint venture structure consists of two entities, a management company and an operating company. The management company serves as the manager of the joint venture, with the board of directors of the management company directing the operating company’s operations. Owens Corning will appoint three members of the management company’s board of directors and Saint-Gobain will appoint two members of the management company’s board of directors. Charles E. Dana, the President of Owens Corning’s Composite Solutions business, will be the President and CEO of the joint venture and will remain President of the Composite Solutions business.

Pursuant to the terms of an Option Agreement, an indirect, wholly owned subsidiary of Owens Corning has the right to acquire Saint-Gobain’s interest in the joint venture at any time after the 48 month anniversary of the closing of the joint venture. Further, Saint-Gobain has the right to sell its interest in the joint venture to such subsidiary at any time after the 48 month anniversary of the closing of the joint venture. The purchase price for Saint-Gobain’s interest will be determined pursuant to a formula set forth in the Option Agreement representing, among other things, a multiple of the average earnings before interest, taxes, depreciation and amortization of the joint venture during the up to 5 year period preceding the purchase and sale of Saint-Gobain’s interest in the joint venture.

The closing of the joint venture is subject to satisfaction of certain conditions, including the receipt of regulatory approvals and consents. It is expected that the joint venture will close in mid-2007. The descriptions of the Master Contribution Agreement, the Joint Venture Agreement and the Option Agreement do not purport to be complete and are qualified in their entirety by reference to the Master Contribution Agreement, the Joint Venture Agreement and the Option Agreement, copies of which are filed as Exhibits 10.1, 10.2 and 10.3, respectively, and are incorporated by reference herein.

Item 2.02. Results of Operations and Financial Condition.

On February 21, 2007, Owens Corning issued an earnings release announcing its financial results for the quarter and year ended December 31, 2006. A copy of the earnings release is attached as Exhibit 99.1. Exhibit 99.1 contains certain financial measures that are considered “non-GAAP financial measures” as defined in Securities and Exchange Commission rules. Exhibit 99.1 also contains the reconciliation of these non-GAAP financial measures to their most directly comparable financial measures calculated and presented in accordance with generally accepted accounting principles.

The information in Item 2.02 of this Current Report is being furnished and shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that Section.

Item 8.01. Other Events.

On February 21, 2007, Owens Corning announced that its Board of Directors has approved a share buy-back program to repurchase up to 5% of Owens Corning’s outstanding common stock. The stock repurchase program authorizes Owens Corning to repurchase shares through open market, privately negotiated, or other transactions.

with U.S. GAAP (in the case of Owens Corning) or IFRS (in the case of Saint-Gobain), presenting fairly, in all material respects, the assets, liabilities, financial condition and the results of operation of such Business and, to the extent not in conflict with U.S. GAAP or IFRS as appropriate, prepared in accordance with the accounting principles, policies, practices, methods and procedures used in calculating such Parent’s Reference Date Balance Sheet) and applied on a consistent basis and (ii) a statement setting forth, in reasonable detail, such Parent’s calculation of (x) its Net Working Capital (as to each Parent, its “Proposed Adjusted Net Working Capital Amount”) and (y) its Net Debt (as to each Parent, its “Proposed Adjusted Net Debt Amount”), in each case as of the close of business on the day prior to the Closing Date. The Review Firm shall have 45 days following such submission to review the consolidating balance sheets solely for the purpose of providing an “agreed upon procedures opinion” in respect of the Proposed Adjusted Net Working Capital Amount and the proposed Adjusted Net Debt Amount, which procedures shall be agreed by the Parents in respect of the Proposed Adjusted Net Working Capital Amount and the Proposed Adjusted Net Debt Amount, which shall be submitted to the Parents on the 45th day following submission to the Review Firm. In the event a Parent disputes the correctness of the other Parent’s Proposed Adjusted Net Working Capital Amount and/or Proposed Adjusted Net Debt Amount, such Parent shall notify the other Parent in writing of its objections within 30 days after receipt of the Review Firm’s opinion and shall set forth, in writing and in reasonable detail, the reasons for its objections. To be assertable, an objection by a Parent with respect to any individual item in respect of the other Parent’s Proposed Adjusted Net Working Capital Amount (it being understood that, for purposes of clarification and not by way of limitation, a method of valuation or the application of an accounting principle used in the preparation of a Parent’s Proposed Adjusted Net Working Capital Amount shall be deemed a separate “item” for purposes of this Section 3.04(a)) (i) must assert that the item was not prepared in accordance with Section 3.04(b); (ii) must set forth such objecting Parent’s determination of the value for such item (provided that the other Parent shall have made available sufficient information to make such determination of value), and (iii) the difference in the Parent’s determination of all items disputed must exceed USD 100,000 in the aggregate. To the extent a Parent does not so object, in writing and in reasonable detail as required and within the time period contemplated by this Section 3.04(a), each Parent shall be deemed to have accepted the other Parent’s calculation and presentation in respect of the matters not subject to objection and such matters shall not be considered to be in dispute. The Parents shall endeavor in good faith to resolve any disputed matters within 15 days after the date on which the last notice of objections was delivered to a Parent. If the Parents are unable to resolve the disputed matters, they shall engage Grant Thornton LLP, London office or, in the event Grant Thornton LLP is conflicted, an internationally known independent accounting firm reasonably acceptable to each Parent (Grant Thornton LLP or such other accounting firm, as the case may be, the “Unaffiliated Firm”), to resolve the matters in dispute (in accordance with Section 3.04(b) and consistent, to the extent possible, with any matters not in dispute). The Parents shall jointly engage the Unaffiliated Firm. Promptly after such engagement of the Unaffiliated Firm, the Parents will provide the Unaffiliated Firm with a copy of this Agreement, the Financial Statements, the statements of Proposed Adjusted Net Working Capital Amounts and/or Proposed Adjusted Net Debt Amounts, as applicable, and any written notices of objections related thereto. Each Parent shall deliver to the Unaffiliated Firm a written submission of its position with respect to the matters in dispute, which submissions shall be delivered by each Parent to the Unaffiliated Firm and to the other Parent simultaneously within 15 days of the engagement of

such Unaffiliated Firm. Each Parent shall thereafter be entitled to submit a rebuttal to the other Parent’s submission, which rebuttals shall be delivered to the Unaffiliated Firm and to the other Parent simultaneously within 30 days of the delivery of the Parents’ initial submissions. The Unaffiliated Firm may request additional information from either Parent, but absent such a request neither Parent may make (nor permit any of its Affiliates or Representatives to make) any additional submission to the Unaffiliated Firm or otherwise communicate with the Unaffiliated Firm, and in no event will either Parent (i) communicate (or permit any of its Affiliates or Representatives to communicate) with the Unaffiliated Firm without providing the other Parent a reasonable opportunity to participate in such communication or (ii) make (or permit any of its Affiliates or Representatives to make) a written submission to the Unaffiliated Firm unless a copy of such submission is simultaneously provided to the other Parent. Either Parent may make a written request for a hearing with the Unaffiliated Firm by delivering notice to the other Parent and the Unaffiliated Firm within 15 days after the submission of rebuttals by the Parents. Within 30 days of such written request, the Unaffiliated Firm shall hold a joint hearing, in person or by teleconference, at which each Parent shall be entitled to make an oral presentation and rebuttal. The Unaffiliated Firm shall have 30 days from the date of such hearing (or, if no such hearing is requested, from the date of submission of written rebuttals) to review the documents provided to it pursuant to this Section 3.04(a) and deliver its written determination with respect to each of the adjustments in dispute submitted to it for resolution. The Unaffiliated Firm shall resolve the differences regarding the statements of Proposed Adjusted Net Working Capital Amounts and/or Proposed Adjusted Net Debt Amounts based solely on the information provided to the Unaffiliated Firm by the Parents pursuant to the terms of this Agreement (and not by independent review). The Unaffiliated Firm’s authority will be limited to resolving disputes with respect to whether the statements of Proposed Adjusted Net Working Capital Amounts were prepared in accordance with the terms of Section 3.04(b) with respect to the individual items on the statements of Proposed Adjusted Net Working Capital Amounts in dispute (it being understood that the Unaffiliated Firm will have no authority to make any adjustments to any Financial Statements or amounts other than the statements of Proposed Adjusted Net Working Capital Amounts and/or Proposed Adjusted Net Debt Amounts and amounts set forth therein that are in dispute). In resolving any disputed item with a positive value, the Unaffiliated Firm may not assign a value to such item greater than the greatest value for such item asserted by either Parent or, in respect of items with a negative value, less than the smallest value for such item asserted by either Parent. The determination of the Unaffiliated Firm in respect of the correctness of each matter remaining in dispute in accordance with this Section 3.04(a) shall be conclusive and binding, in the absence of fraud or manifest error, on the Parents and judgment may be entered thereon as an arbitration award in any court of competent jurisdiction. Each Parent’s Net Working Capital as of the close of business on the day prior to the Closing Date, as finally determined pursuant to this Section 3.04(a), is referred to herein as the “Adjusted Net Working Capital Amount” of such Parent’s Business. Each Parent’s Net Debt as of the close of business on the day prior to the Closing Date, as finally determined pursuant to this Section 3.04(a), is referred to herein as the “Adjusted Net Debt Amount” of such Parent’s Business.

(b) Each Parent’s Proposed Adjusted Net Working Capital Amount shall be determined in accordance with the accounting principles, policies, practices, methods and procedures used in calculating such Parent’s Working Capital Threshold Amount; for the

avoidance of doubt, any impact of fresh start accounting in connection with Owens Corning’s emergence from bankruptcy shall be eliminated.

(c) Subject to any applicable privileges (including the attorney-client privilege), each Parent shall make available to the other and, upon reasonable request, to the Unaffiliated Firm, the books, records, documents and work papers underlying the preparation of such Parent’s Financial Statements and the calculations of such Parent’s Proposed Adjusted Net Working Capital Amount and Proposed Adjusted Net Debt Amount and the relevant personnel of such Parent.

(d) The fees and expenses, if any, of the Unaffiliated Firm shall be shared by the Parents in inverse proportion to their respective success on the merits and such allocation of fees and expenses shall be calculated by the Unaffiliated Firm and shall be conclusive and binding on the Parents.

Section 3.05 Shareholder Loans.

(a) If the OC Total Adjustment, as finally determined, is negative, then on the Adjustment Closing Date OC Topco shall make a loan to the Company, which shall be subordinated to all other obligations of the Company, in the amount of the OC Total Adjustment as if such amount was a positive number (the “OC Shortfall Shareholder Loan”). The OC Shortfall Shareholder Loan shall bear interest from the date of the Closing Date until repayment in full at a rate equal to LIBOR plus 30 basis points. The OC Shortfall Shareholder Loan, including all interest accruing thereon, shall be payable on demand; provided that demand shall only be made after the Exit Date.

(b) If the OC Total Adjustment, as finally determined, is positive, then on the Adjustment Closing Date the Company shall make a loan to OC Topco in the amount of the OC Total Adjustment (the “OC Excess Shareholder Loan”). Each OC Excess Shareholder Loan shall bear interest from the date of the Closing Date until repayment in full at a rate equal to LIBOR plus 30 basis points. The OC Excess Shareholder Loan, including all interest accruing thereon, shall be payable on demand; provided that demand shall only be made after the Exit Date.

(c) If the SG Total Adjustment, as finally determined, is negative, then on the Adjustment Closing Date SG Topco shall make a loan to the Company, which shall be subordinated to all other obligations of the Company, in the amount of the SG Total Adjustment as if such amount was a positive number (the “SG Shortfall Shareholder Loan”). The SG Shortfall Shareholder Loan shall bear interest from the date of the Closing Date until repayment in full at a rate equal to LIBOR plus 30 basis points. The SG Shortfall Shareholder Loan, including all interest accruing thereon, shall be payable on demand; provided that demand shall only be made after the Exit Date.

(d) If the SG Total Adjustment, as finally determined, is positive, then on the Adjustment Closing Date the Company shall make a loan to SG Topco in the amount of the SG Total Adjustment (the “SG Excess Shareholder Loan”). Each SG Excess Shareholder Loan shall bear interest from the date of the Closing Date until repayment in full at a rate equal to LIBOR

plus 30 basis points. The SG Excess Shareholder Loan, including all interest accruing thereon, shall be payable on demand; provided that demand shall only be made after the Exit Date.

(e) All amounts to be paid pursuant to this Section 3.05 shall be paid on the Adjustment Closing Date in immediately available funds by wire transfer to a bank account designated in writing by the payee to the payor at least three Business Days prior to the Adjustment Closing Date.

(f) The obligations of Saint-Gobain and the Company under this Section 3.05 are independent of the obligations of Owens Corning and the Company under Section 3.05 and the obligations of Owens Corning and the Company under this Section 3.05 are independent of the obligations of Saint-Gobain and the Company under Section 3.05.

Section 3.06 Assignment of Contracts and Rights. Anything in this Agreement to the contrary notwithstanding, this Agreement (including the reorganizations contemplated in Article II) shall not constitute an agreement to contribute or otherwise sell, convey, transfer, assign or sublicense any Contract, license or permit constituting a Contributed Asset, or any claim, right or benefit arising thereunder or resulting therefrom, or to enter into any other agreement or arrangement with respect thereto, if an attempted assignment, sale, conveyance, sublicense or transfer thereof, or entering into any such agreement or arrangement, without the consent of a third party, would constitute a breach of, or other contravention under, any agreement to which either Parent, or their respective Asset Transferors, is a party, be ineffective with respect to any party thereto or in any way adversely affect the rights of either Parent, or their respective Asset Transferors, or the transferee thereunder. With respect to any such Contract, license or permit or any claim, right or benefit arising thereunder or resulting therefrom, promptly after the date hereof, the Parties will use reasonable commercial efforts (but without any payment of money or other transfer of value by either Parent or the Company or any of their respective Affiliates to any third party) to obtain any required consent for the assignment, transfer or sublicense of any such Contract, license or permit to the Company, or written confirmation reasonably satisfactory in form and substance to the Parties confirming that such consent is not required. If a required consent is not obtained with respect to any such Contract, license or permit (a “Consent Failure”), the applicable Parent, its Asset Transferors and the Company will cooperate in a mutually agreeable arrangement under which the Company would obtain the benefits thereunder in accordance with this Agreement, including subcontracting or subleasing to the Company or to an Affiliate of the Company, subject to Applicable Law and the terms of any such Contract, license or permit, with the Company or its applicable Affiliate obtaining the claims, rights and benefits of the applicable Parent, or its Asset Transferors, and assuming the obligations under such Contract, license or permit in accordance with this Agreement, and the applicable Parent, or its Asset Transferors, will enforce at the request of and for the benefit of the Company or its applicable Affiliate, with the Company or its applicable Affiliate assuming the applicable Parent’s, or its Asset Transferors, obligations, any and all claims, rights and benefits of the applicable Parents, or its Asset Transferors, against any third party thereto arising from any such Contract, license or permit (including the right to elect to terminate such Contract in accordance with the terms thereof upon the request of the Company). If any Consent Failure occurs and the applicable Parent, or its Asset Transferors, and the Company or its applicable Affiliate have failed to have entered into an arrangement to provide to the Company or its applicable Affiliate the benefits under the relevant Contract, license or

permit, such Parent and the Company shall cooperate following the Closing to obtain such consent or enter into an agreement with respect thereto as soon as reasonably practicable thereafter.

If, in the absence of a protective order or receipt of a waiver hereunder, such Party is, on the advice of counsel, compelled to disclose such confidential or proprietary information, such Party may so disclose the confidential or proprietary information; provided that such Party shall use reasonable commercial efforts to obtain reliable assurance that confidential treatment shall be accorded to such confidential or proprietary information. The provisions of this Section 5.04(d) shall not be deemed to prohibit the disclosure by any Party of confidential or proprietary information to the extent reasonably required (i) to prepare or complete any required Tax Returns or financial statements, (ii) in connection with audits or other proceedings by or on behalf of a Governmental Authority, (iii) in connection with any insurance or benefits claims, (iv) to the extent necessary to comply with any Applicable Laws, (v) to provide services to the disclosing Party or the

Company in accordance with the terms and conditions of any of the Transaction Documents, (vi) in connection with asserting any rights or remedies or performing any obligations under any of the Transaction Documents, or (vii) in connection with any other similar administrative functions in the ordinary course of business; provided that in each such case such Party shall use reasonable commercial efforts to obtain reliable assurance that confidential treatment shall be accorded to such confidential or proprietary information. Notwithstanding the foregoing, the confidentiality restrictions of this Section 5.04 shall not apply to information that (x) is or becomes publicly available other than as a result of a disclosure by the receiving Party, (y) is or becomes available to a Party on a non-confidential basis from a source that, to such Party’s knowledge, is not prohibited from disclosing such information by a legal, contractual or fiduciary obligation, or (z) is or has been independently developed by the receiving Party as evidenced by written documentation.

(e) Each Parent shall, in furtherance of its obligations under this Section 5.04 and at its own expense, provide information to the Company reasonably in its possession regarding the adjusted basis of Contributed Asset for U.S. federal income tax purposes and the value (as determined for purposes of the Treasury Regulations under Section 704) of Contributed Assets and Contributed Subsidiaries measured as of the date of contribution.

Section 5.05 Insurance.

(a) Except for the replacement of existing insurance policies with substantially similar policies upon expiration of existing policies, on and after the date of this Agreement and until the Closing Date, the Parents shall not take or fail to take any action if such action or inaction, as the case may be, would adversely affect the applicability of any insurance (including reinsurance) maintained by the Parents or their Affiliates and in effect on the date of this Agreement that covers all or any part of the assets owned, held or used by the Parents or their respective Affiliates in the conduct of the Parents’ Business or the Transferred Employees. On and after the Closing Date, neither Parent shall intentionally take or intentionally fail to take any action if such action or inaction, as the case may be, would adversely affect any insurance proceeds that would otherwise be payable to the Company on or after the Closing Date to the extent such action relates to an event or occurrence prior to the Closing Date. Neither Parent shall have any obligation to maintain the effectiveness of any such insurance policy, or to make any monetary payment in connection with any such policy, after the Closing Date.

(b) Notwithstanding the provisions of Section 5.05(a), the Parties hereby acknowledge and agree that as of the Closing Date, neither the Company, the Business, any property owned or leased by any of the foregoing, any directors, officers, employees (including the Transferred Employees) or agents of any of the foregoing, shall be insured under any insurance policies maintained by either of the Parents or any of their Affiliates, except (i) in the case of certain claims made policies, to the extent that a claim has been reported as of the Closing Date, (ii) in the case of a policy that is an occurrence policy, to the extent the accident, event or occurrence that results in an insurable loss occurs prior to the Closing Date and has been, is or shall be reported or noticed to the respective carrier by the Company or the applicable Parent in accordance with the requirements of such policies (which claims the applicable Parent shall, at the Company’s cost and expense, use reasonable commercial efforts to pursue on the Company’s behalf, and the net proceeds of which claims (except to the extent they relate to

Excluded Liabilities) shall be remitted promptly to the Company upon receipt thereof), and (iii) otherwise agreed to in writing by the Parties. Except as otherwise agreed to in writing by the Parties, from and after the Closing Date, neither Parent shall have any obligation of any kind to maintain any form of insurance covering all or any part of the Business, its assets or the Transferred Employees.

(c) On and after the Closing Date, the Company shall reimburse the Parents within 30 days of receipt of an invoice for any self insurance, retention, deductible, retrospective premium, cash payment for reserves calculated or charged on an incurred loss basis and similar items, including associated administrative expenses and allocated loss adjustment or similar expenses (collectively, “Insurance Liabilities”) allocated by either Parent to its Business on a basis consistent with Past Practices resulting from or arising under any and all current or former insurance policies maintained by such Parent or its Affiliates to the extent that such Insurance Liabilities relate to or arise out of any activities of the Company. The Company agrees that, to the extent any of the insurers under the insurance polices, in accordance with the terms of the insurance policies, requests or requires collateral, deposits or other security to be provided with respect to claims made against such insurance polices relating to or arising from the Business, the Company shall provide the collateral, deposits or other security or, upon request of the applicable Parent, shall replace any collateral, deposits or other security provided by such Parent or any of its Affiliates to the extent related to or arising out of any activities of the Company.

Section 5.06 Non-Hire and Nonsolicitation of Certain Employees in the Business. From and after the date of this Agreement until the Closing Date, neither Parent nor any of their Affiliates shall, without the prior written approval of the other Parent, directly or indirectly solicit any employee of the other Parent or its Affiliates that has been engaged in the negotiations of the Transaction Documents (including the schedules, exhibits or annexes attached thereto) or who is employed in the Business to enter into an employment relationship with the other Parent or its respective Affiliates; provided, however, that the foregoing shall not apply to (a) individuals hired as a result of the use of an independent employment agency (so long as the agency was not directed to solicit a particular individual or a class of individuals that could only be satisfied by employees of either Owens Corning or Saint-Gobain or any of their Subsidiaries) or as a result of the use of advertisements and other general solicitation (such as an advertisement in newspapers, on Owens Corning or Saint-Gobain websites or internet job sites, or on radio or television) not specifically directed to employees of either Owens Corning or Saint-Gobain or any Affiliate of Owens Corning or Saint-Gobain, or (b) individuals whose employment is terminated by Owens Corning or Saint-Gobain after the date of this Agreement.

Section 5.07 Financial Support Arrangements.

(a) Except as set forth on Schedule 4.02(k)(i)(E) Saint-Gobain and its Affiliates shall not be required to maintain after the Closing Date any other Financial Support Arrangements in connection with Saint-Gobain’s Businesses and may terminate the same as of the Closing Date but only to the extent Saint-Gobain has disclosed in writing to Owens Corning within 30 days of the date hereof those Financial Support Arrangements it intends to so terminate. In furtherance of the foregoing, Owens Corning agrees (i) to use reasonable commercial efforts to arrange for the substitution of any such disclosed Financial Support Arrangements which are to be terminated as of the Closing Date on terms and conditions

reasonably satisfactory to the beneficiaries thereof on the Closing Date, and (ii) to provide financial information concerning the Company reasonably requested by those Persons for whose benefit the Financial Support Arrangements were made.

(b) If, at any time after the Closing Date, (i) any amount is drawn on or paid under any Financial Support Arrangement maintained by the Parents or any of their respective Affiliates in connection with the Parents’ respective Businesses pursuant to which either of the Parents or any of their respective Affiliates is obligated to reimburse the Person making such payment, or (ii) either of the Parents or any of their respective Affiliates pays any amounts under, or any fees, costs or expenses relating to, any such Financial Support Arrangement, the Company shall reimburse the applicable Parent such amounts promptly after receipt from such Parent of written notice thereof accompanied by written evidence of the underlying payment obligation.

Section 5.08 Company Financing. The Company shall use reasonable commercial efforts (and each of the Parents shall use reasonable commercial efforts to assist the Company) to enter into a revolving credit agreement or similar financing arrangement with one or more third party lenders for an aggregate principal amount of at least USD100,000,000 but no greater than 20% of the Company’s equity immediately after the Closing (the “Facility”) at or as soon as possible following the formation of the Company and in any event prior to the Closing; provided that nothing in this Section 5.08 shall require either Party to provide a Financial Support Arrangement in respect of such Facility.

Section 5.09 Competitive Businesses. Unless and until the Closing of the Contemplated Transactions is consummated, the Parents will continue to operate as competitive businesses and will not collaborate in any manner in violation of Applicable Law.

Section 5.10 Certain Intellectual Property Matters.

(a) The Parties agree that the Company shall be granted a term of nine (9) months from the Closing Date in order to discontinue and remove any use by any SG Contributed Subsidiaries of the ‘Saint-Gobain’ and ‘Vetrotex’ trademarks and designs (as displayed in Exhibit G-1) or anything that is substantially or confusingly similar to any of these trademarks and designs, appearing (a) in any domain name; (b) on any external documents such as purchase orders, acknowledgements of receipt and commercial brochures; (c) on the packaging of the Company Products; (d) on buildings and sign posts; and (e) on any other support or medium (such as, but not limited to, company uniforms and merchandising goods).

(c) For a maximum of twelve (12) months following the Closing Date, each Parent and its Affiliates shall redirect internet traffic relating to the Business from their websites to websites of the Company by (i) maintaining a reasonable number of existing links on mutually agreed pages of the website(s) of this Parent and its Affiliates to website(s) of the Contributed

Subsidiaries of this Parent and (ii) redirecting mutually agreed links to such mutually agreed URL(s) within the website(s) of the Company.

(d) Within three (3) months after the Closing Date, each of Owens Corning and Saint-Gobain shall deliver to the Company all the Know How included in the OC Contributed Intellectual Property and SG Contributed Intellectual Property (for purposes of this Section 5.10, “Know How Material”) which is not in place on the Closing Date at the facilities contributed to the Company pursuant to this Agreement (for purposes of this Section 5.10, “Contributed Manufacturing Facilities”). Should any of Company, Owens Corning, or Saint-Gobain subsequently determine that the Company has not received any Know How Material, the corresponding one of Owens Corning and Saint-Gobain shall promptly deliver to the Company such Know How Material.

(e) Unless otherwise agreed by the Parties, Owens Corning and Saint-Gobain shall transfer, or cause to be transferred, promptly after Closing, to the Company or its designee, the documents (including but not limited to patent and trademark files and agreements) that are not held by a Contributed Subsidiary, associated with the OC Contributed Intellectual Property, the OC Third Party Intellectual Property, the SG Third Party Intellectual Property and the SG Contributed Intellectual Property.

(f) The Company and/or any of its Affiliates shall take the steps set forth in (f) and (g) below to permit to be removed from the facilities of the Company and/or its Affiliates any materials or part of materials relating to the Intellectual Property of Saint-Gobain or its Affiliates other than the SG Contributed Intellectual Property, the SG Third Party Intellectual Property and the SG Licensed Intellectual Property (“Excluded Technology”) in tangible form, including any materials prepared by hand, with all copies of the above, and all physical assets or part of physical assets in the possession or control of the Company and/or its Affiliates that describe, discuss, incorporate, embody or reveal any, but only, Excluded Technology (“Excluded Materials”). Excluded Materials shall include, but shall not be limited to, research reports, engineering reports, manufacturing reports, research or development documents of any kind, market studies, batch books, files, notes, letters, studies, computer data or backups and other documents and equipment.

(g) In relation to Saint-Gobain Vetrotex International (Chambéry, France), Vado Ligure (Italy), Changzhou (People’s Republic of China) and Gunsan (Korea) (collectively “Carve-out Facilities”), within twelve (12) months from the Closing Date, Saint-Gobain or its Affiliates shall, in collaboration with the Company and/or its Affiliates, conduct inspections of reasonable scope and duration for Excluded Materials, and remove from the Carve-out Facilities all Excluded Materials. The Company and its Affiliates shall permit Licensor reasonable access to such facilities, during normal business hours, to conduct such inspections.

(h) In relation to the facilities contributed to the Company pursuant to this Agreement other than the Carve-out Facilities, as and when the Company, and/or its Affiliates discover any Excluded Materials at any such facility, such entity shall promptly notify Saint-Gobain of such Excluded Materials and shall make reasonable arrangements for Saint-Gobain to remove such Excluded Materials.

(i) For the avoidance of doubt, the Parties agree that indemnification provisions in this Agreement shall not be limited by any disclaimers or limitations of liability in the SG Intellectual Property License Agreements and/or the OC Intellectual Property License Agreements.

(j) The Parties acknowledge that some of the SG Contributed Intellectual Property, SG Licensed Intellectual Property, OC Contributed Intellectual Property, and OC Licensed Intellectual Property may need to be licensed to third parties in relation to the divestments required in order to close the transaction contemplated by this Agreement. In such case, the Parties acknowledge to have been provided with drafts of any such license agreement, and any such license agreement that licenses rights in the SG Contributed Intellectual Property or the OC Contributed Intellectual Property shall be assigned to US IP Holdco and/or Non-US IP Holdco, as appropriate.

(k) Each of OC Topco and SG Topco hereby covenants, for as long as Saint-Gobain is a shareholder of the Company, to use its best efforts to convince its Parent and its Parent’s then current Affiliates to enter into a good faith negotiation with the Company, and reasonably facilitate such negotiation, for the grant of a license on royalty-bearing and commercially reasonable terms (including a term not limited to the time that Saint-Gobain is a shareholder of the Company) in respect of any Intellectual Property of the Parent or its Affiliates that may be necessary to develop, manufacture, use, market, distribute and sell Company Products.

(l) By February 21, 2007, Owens Corning shall identify to Saint-Gobain from the list set forth in Schedule 4.02(p)(v), such of the patents and patents applications as Owens Corning wishes to have maintained and for which the annuity may still be paid, with or without late payment fee. Saint-Gobain shall cause such annuity and any applicable late payment fee to be paid for such patents and patent applications, such payments to be reimbursed by the Company; provided, however, that if the total amount of such annuity payments exceeds fifteen thousand (USD15,000) US dollars, Saint-Gobain may require that Owens Corning provide funds in advance to Saint-Gobain for such payments, with Owens Corning to be reimbursed by the Company.

(m) Attached in Exhibit G-2 (with respect to Saint-Gobain) and Exhibit G-3 (with respect to Owens Corning) are lists of each Parent’s invention disclosure records, ‘enveloppes Soleau’ and unpublished patent applications. Each Parent shall disclose the content of the items listed on these Exhibits to the other Parent as soon as feasible but no later than ten (10) Business Days after the date of this Agreement; provided, however, that Owens Corning shall only disclose the content of the invention records on Exhibit G-3 that are labeled “In Draft,” “In Search,” or “New Invent.” The Parties shall thereafter discuss in good faith the appropriate allocation of these items between contributed and licensed Intellectual Property. The Parties shall also discuss in good faith the appropriate allocation of the patents listed in Schedule 4.02(p)(v) between contributed and licensed Intellectual Property.

(n) Attached in Exhibit G-4 is a list of Saint-Gobain’s joint development agreements. Attached in Exhibit G-5 (with respect to Owens Corning) and Exhibit G-6 (with respect to Saint-Gobain) are lists of each Parent’s legal opinions. Each Parent shall disclose the

content of the items listed on these Exhibits to the other Parent as soon as feasible but no later than five (5) Business Days after the date of this Agreement. The Parties shall thereafter discuss in good faith how to address (i) any limitations on the rights of the Company to the SG Contributed Intellectual Property, the SG Third Party Intellectual Property, and/or the SG Licensed Intellectual Property that are imposed by Saint-Gobain’s joint development agreements and/or (ii) any risks posed by any third party Intellectual Property that is the subject of any legal opinion listed in Exhibit G-5 and Exhibit G-6 that may arise from the manufacture, use, or sale of Company Products as manufactured, used, or sold in Owens Corning’s or Saint-Gobain’s Business as conducted on or before the Closing Date.

(o) For each patent and patent application listed on Schedule A-1 and Schedule A-6 and listed on the lists attached to Exhibit M and Exhibits N-1 and N-2 for which the deadline for claiming filing priority under the Paris Convention occurs between the date of this Agreement and Closing, the relevant of Owens Corning or Saint-Gobain shall (i) file an application under the Patent Cooperation Treaty (“PCT”) without limit on designated countries, and (ii) at least five (5) Business Days before any such final deadline, notify the other of the non-PCT country(ies) and/or region(s), if any, where it reasonably wishes counterpart application(s) claiming filing priority from each such application to be filed.

(p) For each patent and patent application listed on Schedule A-1 and Schedule A-6 and listed on the lists attached to Exhibit M and Exhibits N-1 and N-2 for which the deadline for filing national stage applications based on any application under the PCT occurs between the date of this Agreement and Closing, the relevant of Owens Corning or Saint-Gobain shall, at least five (5) Business Days before any such final deadline, notify the other of the PCT country(ies) where it reasonably wishes national stage applications based on such PCT application to be filed.

(q) Each of Owens Corning and Saint-Gobain undertakes to, or cause its Affiliates to, file the patent applications in the country(ies) or region(s) indicated by the other pursuant to (o) and (p) above, with each Parent bearing their own costs.

(r) Owens Corning, at its option, shall undertake to apply for trademark registrations for (1) an “OCV” word mark, (2) an OCV logo, and (3) a suitable slogan, for the Company prior to Closing in such countries as the Parties reasonably agree, and shall be reimbursed by the Company after Closing for reasonable related searching and registration costs. In the event that the Company does not reimburse Owens Corning within ninety (90) days of Company’s receipt from Owens Corning of a written request for such reimbursement, then Saint-Gobain shall reimburse Owens Corning for forty percent (40%) of such costs, such reimbursement from Saint-Gobain not to exceed fifteen thousand dollars (USD15,000).

(s) The Company covenants to maintain the IP Holdcos as wholly-owned Subsidiaries of the Company for as long as Saint-Gobain is a shareholder of the Company.

(t) Saint-Gobain hereby covenants, for itself and its Affiliates, that neither Saint-Gobain nor any of its Affiliates will, or will grant to any third party any right to, make, have made, use, have used, develop, have developed, improve, have improved, import, have imported, export, have exported, lease, distribute, have distributed, sell, or have sold any pipes

for water adduction under the patents identified in Exhibit G-7. To avoid any doubt, Owens Corning and its Affiliates and the Company and its Affiliates hereby acknowledge that Saint-Gobain and its Affiliates shall have the right to pursue and prosecute any action to defend such patents in the field of pipes for water adduction.

(u) Neither the Company nor any of its Affiliates shall be entitled, except pursuant to the provisions of the SG Intellectual Property License Agreements, to file a patent application on any item of Know How of Saint-Gobain that is included in a category of Know How identified on Exhibit G-8 as “R&C/TS” (i.e. as being applicable both to the Reinforcements and Composites business and to the Textiles Solutions business of Saint Gobain). Notwithstanding the foregoing, Company or any of its Affiliates may file a patent application on any such item of Know How that: (i) the Company and Saint-Gobain agree is included in SG Contributed Intellectual Property; (ii) is an improvement to, or an invention independently of, any SG Contributed Intellectual Property, SG Third Party Intellectual Property, or SG Licensed Intellectual Property, developed by Company or its Affiliates, or (iii) is Intellectual Property acquired or licensed from Owens Corning or its Affiliates, or any third party. For the avoidance of doubt, it is specified that the designation of a category of Know How as “R&C/TS” in Exhibit G-8 shall not be construed as a presumption that every item of Know How in that category constitutes SG Licensed Intellectual Property rather than SG Contributed Intellectual Property.

Section 5.11 Financial Statements. On or before March 31, 2007, each Parent shall provide the other Parent with the unaudited consolidating balance sheet of such Parent’s Business at December 31, 2006 and the unaudited consolidating income statement of such Parent’s Business for the year ended December 31, 2006. Following March 31, 2007 until the Closing Date, each Parent shall provide to the other Parent, within 45 days of the end of each such Parent’s fiscal quarters, the unaudited consolidating balance sheet of such Parent’s Business as of the close of such fiscal quarter and the unaudited consolidating income statement of such Parent’s Business for such fiscal quarter. Each Parent agrees that the deliverables provided by such Parent under this Section 5.11 will be prepared in all material respects in accordance with U.S. GAAP or IFRS (as applicable) and will present fairly, in all material respects, the assets, liabilities, financial condition, the results of operations of such Parent’s Business at, and for the year ended December 31, 2006 and the applicable fiscal quarter then ended (as the case may be).

ARTICLE VI

FURTHER COVENANTS AND AGREEMENTS OF THE PARTIES

Section 6.01 Further Assurances. Subject to the terms and conditions of this Agreement, each Party shall use reasonable commercial efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary or reasonably desirable under Applicable Law, to consummate or implement the Contemplated Transactions, including providing information reasonably requested by other Persons necessary for such Persons to evaluate whether to consent to the assignment of any Contracts, licenses or permits or related rights or obligations. The Parties shall execute and deliver, and shall cause their respective Affiliates, as appropriate or required as the case may be, to execute and deliver, such other documents, certificates, agreements and other writings and to take such other actions as may be necessary or desirable to consummate or implement the Contemplated Transactions. Except as otherwise expressly set

forth in the Transaction Documents, nothing in this Section 6.01 or elsewhere in the Transaction Documents shall require any Party or any of their respective Affiliates to make any payments or issue any guarantee or other Financial Support Arrangements in order to obtain any consents or approvals necessary or desirable in connection with the consummation of the Contemplated Transactions.

Section 6.02 Certain Filings; Consents. The Parties shall cooperate with each other (a) in determining whether any action by or in respect of, or filing with, any Governmental Authority is required, or any actions, consents, approvals or waivers are required to be obtained in respect of any Contracts, licenses or permits in connection with the consummation of the Contemplated Transactions and (b) subject to the terms and conditions of this Agreement, in taking any such actions or making any such filings, furnishing information required in connection therewith and seeking timely to obtain any such actions, consents, approvals or waivers.

Section 6.03 Public Announcements. On the date of execution and delivery of this Agreement, the Parents shall issue a joint press release in the form mutually agreed by the Parents, such agreement not to be unreasonable withheld Prior to the Closing, the Parties shall not (and shall not permit any Affiliate to) issue any press release or make any public statement with respect to this Agreement or any of the Contemplated Transactions, except as may be required by Applicable Law or any listing agreement with any securities exchange on which its securities are traded, in which case no Party shall issue any such press release or make any such public statement without the prior written consent of the other Parties (to the extent reasonably practicable) and without complying with Applicable Law. Notwithstanding the foregoing, no provision of this Agreement shall (a) relieve either Parent from any of its obligations under the Non-Disclosure Agreement or (b) terminate any of the restrictions imposed upon the Parties by Section 5.03.

Section 6.04 Antitrust or Competition Law Matters.

(a) Parents shall, as promptly as practicable and before the expiration of any relevant legal deadline, file with any Governmental Authority, any filings, reports, information and documentation required for the transactions contemplated hereby pursuant to any Antitrust or Competition Law as set forth in Schedule 6.04. Parents shall, as promptly as practicable respond, to any request for information and documents or compulsory process from any Governmental Authority, including inter alia a request for additional information and documents under the Hart-Scott-Rodino Antitrust Improvement Act, as amended. Parents shall furnish to each other’s counsel such necessary information and reasonable assistance as the other may request in connection with its preparation of any filing or submission that is necessary under any Antitrust or Competition Law or requested by any Governmental Authority. To the extent that a merger filing may be required under Turkish laws, the Parties agree that a filing will be made as soon as all relevant documents have been translated to allow a complete filing and that they will not take any action outside of the ordinary course of business or as otherwise permitted by this Agreement that would change the manner in which the parties conduct business in the territory of the Republic of Turkey until clearance is received from the Turkish Competition Authority. Parents shall share equally in all filing and other similar fees payable in connection with such filings, including local counsel fees, it being understood that such local counsel fees shall include the fees allocated by Saint-Gobain for in-house legal support as previously agreed in writing between the Parties.

(b) Parents shall use their commercially reasonable efforts to (i) obtain promptly any clearance or approval required under any Antitrust or Competition Law for the consummation of this Agreement and the transactions contemplated hereby, (ii) close or have closed any investigation by any Governmental Authority relating to the transactions contemplated in this Agreement, and shall keep each other apprised of the status of any communications with, and any inquiries or requests for additional information from, the U.S. Federal Trade Commission and the U.S. Department of Justice, the European Commission, and other Governmental Authority and shall comply promptly with any such inquiry or request. The Parents shall consult with each other on whether to contest together, administratively or in court, any ruling, order or other action of any Governmental Authority in respect of the transactions contemplated by this Agreement. In the event that one Party decides to contest such ruling, order or action on its own, the other Party shall be obligated to provide the Party initiating the contest with all reasonable assistance in the conduct of such contest.

(c) The Parents commit to instruct their respective counsel to cooperate with each other and use commercially reasonable efforts to facilitate and expedite the identification and resolution of any issues and, consequently, the expiration of the applicable waiting period and the waiting periods, approvals or clearances under any Antitrust or Competition Law or the conclusion of any investigation by any Governmental Authority at the earliest practicable dates. Said commercially reasonable efforts include, but are not limited to, exchanging information and proving such other assistance reasonably necessary to obtain approvals and clearances under any Antitrust or Competition Law. Furthermore, each Parent to this Agreement shall promptly notify the other Parent of any oral or written communication it receives from any Governmental Authority relating to the matters that are the subject of this Agreement, permit the other Parent to review in advance any communications proposed to be made by such other Parent to any

Governmental Authority and shall provide the other party with copies of all correspondence, filings or other communications to and from any Governmental Authority. Each Parent to this Agreement shall not agree to participate in any meeting with any Governmental Authority in respect to any such filings, investigations or other inquiry unless it consults with the other Parent in advance and, to the extent permitted by such Governmental Authority, gives the other Parent the opportunity to attend and participate in such meetings. It is nevertheless understood that Owens Corning and its counsel will take the lead on all communications with any Governmental Authority.

Section 6.05 Agreements Regarding Tax Matters.

(a) Each Parent shall (i) provide the Company with such assistance as may be reasonably requested in connection with the preparation of any Tax Return or any audit or other examination by any Tax Authority or proceeding involving any Governmental Authority relating to liability for Taxes, (ii) retain for a period of six years following the end of the calendar year in which the Closing occurs, or if longer, the period required by applicable Tax law, and provide to the Company all records and other information that may be relevant to any such Tax Return, audit or examination, proceeding or determination, and (iii) provide the Company with a copy of any final determination of any such audit or examination, proceeding or determination that affects any amount required to be shown on any Tax Return of the Company or any of its Subsidiaries for any period. Without limiting the generality of the foregoing, each Parent shall retain, until the expiration of the applicable statutes of limitation (including any extensions thereof), or if longer, the period required by applicable Tax law, copies of all Tax Returns, supporting work schedules and other records (including any other documents or information required to be retained in accordance with applicable Tax law) relating to Tax periods or portions thereof ending on or prior to the Closing Date that concern the Contributed Assets, the Contributed Subsidiaries or the Assumed Liabilities. In furtherance of the foregoing, each Parent shall provide any information reasonably required by the Company for Tax purposes and shall cooperate with the Company with respect to matters relating to the intended Tax treatment of the Company, the Parents and their respective Affiliates (including without limitation with respect to any information reporting or gain recognition agreement obligations that the Parents, the Company or their respective Subsidiaries may have as a result of or in connection with the transactions contemplated under this Agreement).

(b) The Parents agree that the transactions contemplated by this Agreement constitute a disposition of a trade or business within the meaning of Section 41(f)(3) of the Code. The Parents will provide to the Company upon request all information necessary to permit the Company to apply the provisions of Section 41(f)(3)(A) of the Code.

(c) The Company shall timely prepare all Tax Returns with respect to the Company and the Contributed Subsidiaries for any Tax period beginning before and ending after the Closing Date (a “Straddle Period”) and all Tax Returns for any Tax period ending on or before the Closing Date (a “Pre-Closing Period”) that is to be filed after the Closing Date and, with the prior written consent of the Parent that contributed the Contributed Subsidiary relating to each such Tax Return (which consent shall not be unreasonably withheld or delayed), shall file or cause to be filed such Tax Returns. SG Parent acknowledges and agrees that Tax Returns prepared by the Company pursuant to this Section 6.05(c) may include, at the discretion of the

Company, United States federal (and applicable state and local) Tax Returns of SG Contributed Subsidiaries for Pre-Closing Periods reflecting the election of a tax year for United States federal (and applicable state and local) Tax purposes that ends on the day prior to the Closing Date; provided (i) such elections do not require any such SG Contributed Subsidiaries to change their reporting period for any purposes other than United States tax purposes (including financial accounting and non-US tax purposes), (ii) the Company has reasonably determined that such elections are permitted under applicable law and (iii) such elections are not reasonably expected to materially increase the United States tax liability of any of the SG Contributed Subsidiaries or of Saint-Gobain or of any of their Affiliates.

(d) The Company shall pay or cause to be paid all Taxes with respect to the Company, the Contributed Assets and the Contributed Subsidiaries shown as due on the Tax Returns filed for a Straddle Period or a Pre-Closing Period pursuant to Section 6.05(c); provided, that each Parent shall be liable for and shall reimburse the Company for any such Taxes attributable to the portion of such Straddle Period beginning before and ending as of the Closing Date or to a Pre-Closing Period (including Taxes resulting from the transactions contemplated by this Agreement but, except as provided in Section 13.03, not including transfer, stamp, registration, sales, use, value added and similar Taxes imposed with respect to the Parents’ Reorganizations or the contributions contemplated by Article III) and attributable to such Parent’s Contributed Subsidiaries (except to the extent that such Taxes were taking into account as a liability in calculating Adjusted Net Working Capital). For this purpose, any Tax that becomes due after the Closing Date by reason of an action of the Company with respect to any unrecognized gain (whether or not realized) in the Contributed Assets or Contributed Subsidiaries (including the Company’s failure to use them in the manner described in Treas. Reg. Section 1.367(e)-2(b)(2)(i)(E)((i)) shall not be treated as Tax attributable to a Pre-Closing Period of the portion of a Straddle Period ending before the Closing Date. Any Taxes arising from or with respect to the Contributed Subsidiaries or the Business for a Straddle Period shall be apportioned between the Company and the appropriate Parent by allocating real and personal property taxes between such Parent and the Company based on the ratio of the number of days in the Straddle Period occurring before the Closing Date to the number of days in the Straddle Period occurring on or after the Closing Date and by assuming, with respect to all other Taxes, that the Contributed Subsidiary or Business had a tax period that ended at the close of business on the day immediately prior to the Closing Date and closed its books as of that time. The Company shall reimburse the appropriate Parent for any such Taxes paid by the Parents for which the Company is liable pursuant to this Section 6.05(d).

(e)Each Parent shall be liable for, and shall hold harmless and indemnify the other Parent, the Company and its Subsidiaries (including the Contributed Subsidiaries) against, Taxes (and related Damages) imposed on the other Parent, the Company, any of its Subsidiaries or the Contributed Assets that are attributable to such Parent’s Contributed Subsidiaries and to the portion of a Straddle Period beginning before or on and ending as of the Closing Date or to a Pre-Closing Period (excluding Taxes taken into account as a liability in calculating such Parent’s Adjusted Net Working Capital and taking into account any resulting actual refund or reduction in liability for Taxes imposed on the Company or any of its Subsidiaries attributable to the portion of the Straddle Period beginning before and ending as of the Closing Date or to a Pre-Closing Period). For the avoidance of doubt, each Parent’s indemnification obligation under this Section

6.05(e) shall include any Taxes imposed as a result of a later audit or examination or required by law and shall not be subject to the Indemnity Caps or the Indemnity Threshold.

(f) The Company shall engage one or more independent accounting firms of national reputation in the applicable jurisdictions to assist in the preparation of the Tax Returns of the Company and its Subsidiaries.

(g) The following procedures shall apply with respect to any written claim with respect to Taxes made by any Governmental Authority or other Person that, if pursued successfully, could serve as the basis for a claim for indemnification of the Company or its Subsidiaries under this Agreement (a “Tax Claim”):

(i) If any Governmental Authority or other Person asserts a Tax Claim, if the party hereto first receiving notice of such Tax Claim is the Company or its Subsidiaries, than the Company shall within 10 days of receipt provide written notice of such Tax Claim to the party hereunder that would be required to indemnify the Company hereunder in respect of such Tax (the “Tax Indemnifying Party”), and if the party hereto first receiving notice of such Tax Claim is the Tax Indemnifying Party, then such Tax Indemnifying Party shall promptly provide written notice of such Tax Claim to the Company. Such notice in each case shall specify in reasonable detail the basis for such Tax Claim and shall include a copy of any relevant correspondence received from the Governmental Authority or other Person.

(ii) The Company shall control the defense and prosecution of all Tax Claims. The Tax Indemnifying Party shall cooperate in good faith with the Company and its authorized representatives in order to contest effectively such Tax Claim. The Company shall inform the Tax Indemnifying Party of all developments and events relating to such Tax Claim (including providing to Tax Indemnifying Party copies of all written materials relating to such Tax Claim), and Tax Indemnifying Party or its authorized representatives shall be entitled, at the expense of Tax Indemnifying Party, to attend and participate in, but not control, all conferences, meetings and proceedings relating to such Tax Claim. The Company shall provide the Tax Indemnifying Party drafts of all written submissions relating to such Tax Claims in advance for comment and review.

(iii) The Company shall not enter into any compromise or settlement of such Tax Claim that would result in any Tax detriment to the Tax Indemnifying Party without the consent of such party, such consent not to be unreasonably withheld or delayed; provided however that if in any case such consent is not granted, the Company may elect to enter into such compromise or settlement of such Tax Claim notwithstanding, if it obtains advice from an expert on taxation for the jurisdiction in question of national standing in the relevant jurisdiction to the effect that the compromise or settlement is in the best interests of both the Company and the Tax Indemnifying Party.

(h) The Company shall, at the request of SG Topco, following the reasonable determination of Saint Gobain that gain realized for US federal income tax purposes as a result of the conversion of the SG Contributed Subsidiary holding the SG Contributed Assets located in the United States to a disregarded entity for such purposes qualifies for non-recognition taking into account the provisions of Sections 332 and 367(e)(2) of the Code cause an authorized officer

of the Company to sign the statement referred to in Treas. Reg. Section 1.367(e)-2(b)(2)(i)(E)(5)(ii) with respect to the SG Contributed Assets located in the United States, in form and substance reasonably acceptable to the Company (it being understood that the Company in evaluating the substance of such statement may require an independent valuation or other equivalent valuation information regarding the value of assets reported thereon).

Section 6.06 Administration of Accounts. All payments and reimbursements received by either Parent or their respective Affiliates after the Closing Date that would have been payable to a Contributed Subsidiary prior to the Closing Date shall be promptly paid over to the Company without right of set-off. All payments and reimbursements that constitute Excluded Assets or relate to an Excluded Liability received by the Company after the Closing Date shall be promptly paid over to applicable Parent without right of set-off.

Section 6.07 Undisclosed Contracts. Promptly after the date hereof, subject to Applicable Law, each of Owens Corning and Saint-Gobain shall, with respect to each of the Contracts of its Business that contain confidentiality or non-disclosure provisions requiring the specific approval of customers or other Persons for disclosure of the terms thereof (the “Undisclosed Contracts”), use reasonable commercial efforts to obtain the approval of customers or other Persons as necessary to enable (i) each Parent and its Representatives to conduct a review of the Undisclosed Contracts of the other Parent’s Business to which such Parent shall have been denied access prior to the date hereof, and (ii) the Company to conduct the Business from and after the Closing Date. Upon receiving the approvals of customers or other Persons, as the case may be, as contemplated by the preceding clause (i), each Parent shall permit the other Parent’s Representatives to conduct a review of such Undisclosed Contracts, subject to the terms and conditions of the approvals, the provisions of the Confidentiality Agreement and the provisions of Applicable Law.

Section 6.08 No Transfer or Assumption of Asbestos Liabilities. No Party, nor any Contributed Subsidiary or Existing JV, is (as result of this Agreement or any of the transactions contemplated hereby) assuming or responsible for any liabilities or obligations (under any legal theory or cause of action, including without limitation, based on theories of fraudulent conveyance, successor liability or piercing the corporate veil) arising out of, resulting from or related to, any Asbestos Materials or Asbestos Laws, arising out of or relating in any manner to, any other Party and/or any of its current or former divisions or Affiliates (or any of their respective predecessors) or any of their respective current or former operations, transactions, activities, conditions, occurrences, acts or omissions.

Section 6.09 Affiliate Agreements. Except as expressly contemplated by the Transaction Documents, (i) Owens Corning shall cause all agreements between an OC Contributed Subsidiary and any Affiliate thereof (other than another OC Contributed Subsidiary) to be terminated prior to the Closing and (ii) Saint-Gobain shall cause all agreements between an SG Contributed Subsidiary and any Affiliate thereof (other than another SG Contributed Subsidiary)to be terminated prior to the Closing.

days of Signing” on Schedule 6.10 attached hereto and (ii) each contract listed Schedule 4.02(w) to Owens Corning.

ARTICLE VIII

EMPLOYEE AND EMPLOYEE BENEFIT MATTERS

Section 8.01 Employee and Employee Benefit Matters. The Parties agree as to employee and employee benefit matters as set forth below:

(a) Employment of Business Employees. As of the Closing Date, the Parents shall cause the Company and its Subsidiaries to (i) continue to employ (where employment continues automatically by operation of law) on the Closing Date, or (ii) offer employment (where employment does not continue automatically by operation of law) as of the Closing Date to, each Business Employee who is actively employed immediately prior to the Closing Date (the employees described in clauses (i) and (ii) who continue employment with the Company or its Subsidiaries or accept such offers of employment with the Company or its Subsidiaries will be referred to as the “Company Employees”). The Company also shall, or shall cause its Subsidiaries to, continue to employ (where employment continues automatically by operation of law) or offer re-instatement or employment (where employment does not continue automatically by operation of law), as the case may be, to each Business Employee who is not actively employed immediately prior to the Closing Date and who has a right of re-instatement (collectively, “Inactive Employees”), in each case on return from any leave or other absence to the extent the Parents or their respective Affiliates would have been required immediately prior to the Closing Date to reinstate such Inactive Employee pursuant to Applicable Law or any applicable Parent policy (pursuant to the terms of such policy as in effect as of the date hereof). A list of Inactive Employees as of February 1, 2007 is set forth on Schedule 8.01(a). Such list shall be updated by the Parents as of the Closing Date. Any Inactive Employee who returns to active employment or becomes actively employed by the Company or its Subsidiaries upon conclusion of his or her leave or absence as set forth in this Section 8.01(a) shall be treated as a Company Employee upon his or her return to active employment with the Company or its Subsidiaries. Business Employees who do not become actively employed by the Company or its Subsidiaries shall not be considered Company Employees under this Agreement, and the Company or its Subsidiaries shall have no obligations or liability with respect to such employees except for any benefits payable under any Transferred DB Plans as described in this Article VIII. For such employees, any and all employment-related obligations and liabilities (except for any benefits payable under any Transferred DB Plans as described in this Article VIII) shall remain with the applicable Parent or its Affiliates (other than the Company and its Subsidiaries).

(b) Terms and Conditions of Employment. For all hourly and salaried Company Employees who are not covered by a collective bargaining agreement that covers the terms and conditions of employment and that will be assumed by the Company as of the Closing Date, except where Applicable Law provides otherwise, the Company shall, or shall cause its

Subsidiaries to, initially offer wages (including participation in variable compensation plans), hours, benefits and other terms and conditions of employment that are comparable in the aggregate (except for equity compensation) to the wages, hours, benefits and other terms and conditions of employment that were provided to such employees by Owens Corning and Saint-Gobain and/or their Affiliates immediately prior to the Closing Date; provided, however, the base salary, work location, and any other applicable benefits to be offered to Company Employees shall be such that the formation of the Company and/or transfer of employment to the Company or any of its Subsidiaries should not result in the entitlement to severance benefits under any plan of the Parents or their Affiliates or Applicable Law. Subject to the requirement in the preceding sentence regarding the avoidance of triggering severance payments, the Company shall have the sole discretion to determine the wages, employee benefits and terms of employment to be provided to Company Employees; provided, however, the intended employee benefits to be initially provided to the Company Employees shall include those provided through: the Transferred DB Plans, Transferred DC Plans, Retained DB Plans, Retained DC Plans, Risk Plans and new stand-alone plans as set out in Schedule 8.01(b) (collectively, the “Benefit Schedules”). Notwithstanding the foregoing, where the Benefit Schedules specifically state that a “Special Treatment/Exception” shall apply, the terms of such schedule shall control. The Parties agree that, in any jurisdiction, the Company and its Subsidiaries will after the Closing Date either: (i) endeavor to participate in the Retained Plans, as applicable, (ii) assume responsibility for the Transferred Plans, as applicable, or (iii) shall establish or not establish new stand-alone plans, as applicable. In the event that the Company offers to enter into an individual arrangement with a Company Employee, then the Company Employee may choose to enter into such arrangement in lieu of receiving the compensation and benefits specified above.

(c) Employees Representative Agreements. As of the Closing Date, the Company shall, or shall cause its Subsidiaries, consistent with Applicable Law, to (i) continue to give effect to any collective bargaining agreement or similar agreement (where the agreement continues automatically by operation of law) that covers Company Employees to the extent required by Applicable Law and to the same extent the respective Parents and their Affiliates were required to do so, or (ii) except as otherwise expressly agreed upon by the Parents, initially assume all rights, obligations and liabilities under any collective bargaining agreement or similar agreement (where the agreement does not continue automatically by operation of law) that covers Company Employees, and to recognize and bargain in good faith with any union that has been certified or recognized as the collective bargaining representative of Company Employees who are employed by the Company and/or its Subsidiaries. The Parents and their Affiliates and the Company and its Subsidiaries shall cooperate and take all necessary steps and fulfill all of their respective obligations under Applicable Law and the terms of any applicable agreement, including obtaining any prior approvals or consents, or engaging in any prior discussions or consultations, on a timely basis, as may be legally required in order to effectuate the foregoing.

(d) Credit for Service. The Company shall, or shall cause its Subsidiaries to, credit Company Employees for service earned prior to the Closing Date with the Parents and their Affiliates, or any of their respective predecessors members of the Parent group of companies, in addition to service earned with the Company and its Subsidiaries on or after the Closing Date, (i) to the extent that service is relevant for purposes of eligibility, vesting or the calculation of vacation, sick days, severance, layoff and similar benefits under any retirement (other than benefit accrual purposes with respect to Transferred DB Plans) or other employee

benefit plan, program or arrangement of the Company or any of its Subsidiaries for the benefit of the Company Employees on or after the Closing Date, and (ii) for such additional purposes as may be required by Applicable Law; provided, however, that (A) the service that is credited pursuant to this Section 8.01(d) may not be greater than the service credited for the applicable purpose by the Parent and its Affiliates immediately prior to Closing Date, and (B) Company Employees shall not receive any such service credit (1) where it would result in duplication of benefits, or (2) in excess of the amount permitted under Applicable Law.

If Company Employees participate in a Retained Plan sponsored by a Parent or any of its Affiliates (other than the Company or its Subsidiaries), on or after the Closing Date, the Parent shall, or cause its Affiliates to, credit such Company Employees with service earned on and after the Closing Date with the Company and its Subsidiaries (and any of their successors) for purposes of vesting and eligibility and to recognize the effect of future pay increases applicable in such plan; provided, however, that Company Employees shall not receive any such service credit where it results in a duplication of benefits.

(e) Pre-existing Conditions; Coordination. Where applicable, the Company shall, or shall cause its Subsidiaries to, waive limitations on benefits relating to any pre-existing conditions of the Company Employees and their eligible dependents to the extent that such limitations were waived under the applicable OC Benefit Plan or SG Benefit Plan. Where applicable, the Company shall, and shall cause its Subsidiaries to, recognize for purposes of annual deductible and out-of-pocket limits under their health plans applicable to Company Employees, deductible and out-of-pocket expenses paid by Company Employees and their respective dependents under the Parents’ or any of their Affiliates’ health plans in the calendar year in which the Closing Date occurs to the extent that the respective Parents, as applicable, provide the Parents and the Company as of the Closing Date with detailed information as to the amount of such deductible and out-of-pocket expenses paid by the Company Employees.

Section 8.02 Allocation of Pre-Closing Employment Liability. Owens Corning and its Affiliates (other than the Company and its Subsidiaries) shall, other than with respect to (i) Retirement Benefits and Risk Benefits provided in Section 8.04 and Section 8.05 and (ii) any employment or benefit litigation arising out of claims alleging discrimination, be responsible for any and all employment-related obligations and liabilities (including but not limited to wages, bonuses, commissions, vacation, leave, employee benefits, severance, and other compensation), for OC Employees incurred prior to the Closing Date, or arising out of conduct by Owens Corning or its Affiliates first occurring prior to the Closing Date, to the extent it is related to the period up to the Closing Date, under any Applicable Laws, regulations, collective bargaining agreements, or other agreements, or imposed by any administrative, judicial, or governmental body. Saint-Gobain or its Affiliates (other than the Company and its Subsidiaries) shall, other than in relation to (i) Retirement Benefits and Risk Benefits provided in Section 8.04 and Section 8.05 and (ii) any employment or benefit litigation arising out of claims alleging discrimination, be responsible for any and all employment-related obligations and liabilities (including but not limited to wages, bonuses, commissions, vacation, leave, employee benefits, severance, and other compensation), for SG Employees incurred prior to the Closing Date, or arising out of conduct by Saint-Gobain or its Affiliates first occurring prior to the Closing Date, to the extent it is related to the period up to the Closing Date, under any Applicable Laws, regulations,

collective bargaining agreements, or other agreements, or imposed by any administrative, judicial, or governmental body.

Section 8.03 Allocation of Post-Closing Employment Liability. The Company or its Subsidiaries shall be responsible for any and all employment-related obligations and liabilities for Company Employees not covered by (i) Section 8.02 or (ii) the Retirement Benefits and Risk Benefits provided in Section 8.04 and Section 8.05, provided, however, that the Company shall not be responsible for any strike or strike-related conduct by employees of the Business prior to the Closing Date.

Section 8.04 Allocation of Retirement Benefit Liabilities.

(a) Liabilities for Transferred DB Plans.

(i) The Parties agree that the sponsorship, obligations, and liabilities in respect of the Transferred DB Plans will be transferred to and assumed by the Company or any of its Subsidiaries with effect on and from the Closing Date by operation of Applicable Law or by the transactions contemplated by this Agreement.

(ii)

(A) For each Transferred DB Plan that was sponsored by Owens Corning or its Affiliates immediately prior to Closing (the “OC Transferred DB Plans”), Owens Corning’s actuary (the “OC Actuary”) and Saint-Gobain’s actuary (the “SG Actuary,” together with the OC Actuary, the “Actuaries”) shall determine within 60 days of the Closing Date the value of the projected benefit obligation of such OC Transferred DB Plan based on a FAS/IAS methodology and on the actuarial assumptions set forth on the applicable Benefit Schedule and the market value of the assets of each such Transferred DB Plan as of the Closing Date. For each Transferred DB Plan that was sponsored by Saint-Gobain or its Affiliates immediately prior to Closing (the “SG Transferred DB Plans”), the Actuaries shall determine within 60 days of the Closing Date the value of the projected benefit obligation of such SG Transferred DB Plan based on a FAS/IAS methodology and on the actuarial assumptions set forth on the applicable Benefit Schedule and the market value of the assets of each such Transferred DB Plan as of the Closing Date. The excess of the value of the projected benefit obligation of a Transferred DB Plan over the current value of the assets of such Transferred DB Plan as of the Closing Date constitutes the “Unfunded Liabilities” of such Transferred DB Plan. Within 60 days after the Closing Date, the Actuaries shall determine the aggregate Unfunded Liabilities for all the OC Transferred DB Plans (the “OC Pre-Close Unfunded Liabilities”) and the aggregate Unfunded Liabilities for all the SG Transferred DB Plans (the “SG Pre-Close Unfunded Liabilities”).

(B) The OC Pre-Close Unfunded Liabilities and SG Pre-Close Unfunded Liabilities shall be adjusted as determined by the Actuaries in accordance with the methodology as set forth in Schedule 8.04(a)(ii)(B) within 60 days following: (i) the end of each calendar year prior to the termination of the Joint Venture, and (ii) the termination of the Joint Venture, taking into account any contributions made to a Transferred DB Plan and any benefit payments made to a Company Employee directly by the Company or its Subsidiaries with

respect to a Transferred DB Plan in the relevant period. Such adjusted amounts shall be referred to as the “Adjusted OC Pre-Close Unfunded Liabilities” and the “Adjusted SG Pre-Close Unfunded Liabilities”, as applicable.

(C) Each time that an adjustment is made to the OC Pre-Close Unfunded Liabilities and SG Pre-Close Unfunded Liabilities in accordance with Section 8.04(a)(ii)(B) above in respect of payments made to fund a Transferred DB Plan or benefit payments to a Company Employee directly by the Company or its Subsidiaries with respect to a Transferred DB Plan, an allocation of the portion of each such payment that will be charged to the applicable Parent shall be made by the Actuaries based on the percentage of such payment that is attributable to the pre-closing service in accordance with the methodology set forth in Schedule 8.04(a)(ii)(B). The amount chargeable under this Section 8.04(a)(ii)(C) to a Parent shall be contributed by the applicable Parent in cash to the Company if such payment would not result in a Tax to the Company, or its Subsidiaries or Parent or its Affiliates or loss of Tax deduction which the Company, or its Subsidiaries or Parent or its Affiliates would have received if payment had been made directly by Parent for such benefits or contributions, or shall be accounted for as an OC Shortfall Shareholder Loan or SG Shortfall Shareholder Loan, as applicable, pursuant to Section 3.05.

(D) Each time that the Actuaries are required to make a determination hereunder, the Parents shall instruct the Actuaries to use all reasonable efforts to reach mutual agreement as to the determination that is to be made. Saint-Gobain shall make available to the Owens Corning Actuary all information reasonably required by the Owens Corning Actuary to verify the Saint-Gobain Actuary’s calculations. Owens Corning shall make available to the Saint-Gobain Actuary all information reasonably required by the Saint-Gobain Actuary to verify the Owens Corning Actuary’s calculations. The fees and expenses of Saint-Gobain Actuary shall be paid by Saint-Gobain and those of Owens Corning Actuary shall be paid by Owens Corning. If the Actuaries are not able to reach mutual agreement with respect to any calculation required to be made hereunder by the Actuaries, then the determination of such calculation shall be referred for a final decision to an independent actuary to be nominated jointly by Saint-Gobain and Owens Corning. The Parties shall request that the actuary so appointed use all reasonable efforts to make its determination within 10 business days. The person so appointed shall act as an expert and not as an arbitrator, such person’s decision shall be final and binding, and such person’s fees and expenses shall be shared equally by Saint-Gobain and Owens Corning.

(E) During the period from the Closing Date until the termination of the Joint Venture, the Company and its Subsidiaries will not without the consent of both Parents pay any amounts to fund a Transferred DB Plan in excess of the minimum funding requirements under Applicable Law except with respect to contributions made to the funded OC Transferred DB Plan in Japan up to the amount of the OC Pre-Close Unfunded Liabilities and Ongoing Service Cost with respect to such plan.

(iii) Upon termination of the Joint Venture, in the event that the Adjusted SG Pre-Close Unfunded Liabilities exceed an amount equal to two-thirds of the Adjusted OC Pre-Close Unfunded Liabilities, Saint-Gobain shall pay to Owens Corning, in USD, within 30 days after the calculation of such amounts are finalized, an amount equal to the

Adjusted SG Pre-Close Unfunded Liabilities minus two-thirds of the Adjusted OC Pre-Close Unfunded Liabilities, or if the payment date of the Exit Price of the Option under the Option Agreement has not yet occurred, such amount shall be considered a reduction in the Exit Price as set forth in the Option Agreement (the “SG Pension Exit Price Adjustment”). In the event that the Adjusted SG Pre-Close Unfunded Liabilities is less than an amount equal to two-thirds of the Adjusted OC Pre-Close Unfunded Liabilities, Owens Corning shall pay to Saint-Gobain, in USD, within 30 days after the calculation of such amounts are finalized, an amount equal to two-thirds of the Adjusted OC Pre-Close Unfunded Liabilities minus the Adjusted SG Pre-Close Unfunded Liabilities, or if the payment date of the Exit Price of the Option under the Option Agreement has not yet occurred, such amount shall be considered an increase in the Exit Price as set forth in the Option Agreement (the “OC Pension Exit Price Adjustment”).

(b) Liabilities for Transferred DC Plans. The Parties agree that the sponsorship, obligations, and liabilities in respect of the Transferred DC Plans will be transferred to and assumed by the Company or any of its Subsidiaries with effect on and from the Closing Date by operation of Applicable Law or by the transactions contemplated by this Agreement.

(c)Consents for Transferred Plans. The Parties shall use their best reasonable efforts to obtain as soon as practicable and in close consultation (if requested) with the Company or its Subsidiaries, any applicable consents, consultations and approvals required by Applicable Law to transfer or caused to be transferred to the Company or any of its Affiliates the liabilities and assets of the Transferred Plans, including but not limited to the consent, consultation and approval of any applicable works council, Company Employee, Governmental Authority, trustee, insurer, or other entity involved in the management of such plan. Notwithstanding the foregoing, in the event that Applicable Law expressly prohibits the transfer of plan assets for the benefit of any Company Employee, even with appropriate consents, consultations, and approvals like those described above, the parties agree that they shall in good faith cooperate and work with each other to take such actions as are permissible under such Applicable Law or practice to carry out to the fullest extent possible the spirit and purposes of such provision.

(d) Liabilities for Retained DB Plans in which Company participates post Closing.

(i) Owens Corning or any of its Affiliates or Saint-Gobain or any of its Affiliates, as applicable, shall bear any pre-Closing liabilities associated with any Retained DB Plans where the Company or any of its Subsidiaries are admitted to participate in such plan with effect on and from the Closing Date in respect of the Company Employees that are affected by post-Closing events (e.g. – future pay increases, or service counting towards eligibility for subsidized benefits, plan amendments) save that the Company or any of its Subsidiaries shall bear the costs of any such pre-Closing liabilities that are increased by a collective dismissal procedure implemented by the Company or by the relevant Subsidiary thereof. The Company shall notify the Parents in advance of planned pay increases and other anticipated events affecting liabilities in any such Retained DB Plans, as applicable.

(ii) If Company Employees participate in a Retained Benefit Plan sponsored by Owens Corning or any of its Affiliates (other than the Company or its

Subsidiaries), or Saint-Gobain or any of its Affiliates (other than the Company or its Subsidiaries) (in either case, the “Sponsoring Entity”), as the case may be, on or after the Closing Date, the annual calendar year cost (“Annual Cost”) to be charged to the Company with respect to such participation shall equal (i) the Ongoing Service Cost, as applicable, plus or minus (ii) the increase or decrease in the projected benefit obligation in respect of all service credited under the plan for Company Employees or retirees affected by a collective dismissal procedure implemented by the Company or by one of its Subsidiaries. The Company or its relevant Subsidiary shall pay, or otherwise credit in a tax advantageous manner, the Annual Cost in full to the Sponsoring Entity by the end of the applicable calendar year. In the event any Annual Cost is unpaid, or otherwise not credited, as of the start of a year, an additional annual charge (“Additional Annual Charge”) will be imposed on the Company or its relevant Subsidiary that will consist of (a) the interest cost on accumulated unpaid Annual Costs since the establishment of the Company or its relevant Subsidiary, and (b) a prorata share of any annual FAS 87 or FAS 106 gain/loss amortization, based on the ratio of accumulated unpaid Annual Costs of the Company or its relevant Subsidiary since the establishment of the Company or the relevant Subsidiary to the plan’s total projected benefit obligation.

(e) Liabilities for Retained DC Plans in which the Company participates post Closing. The Parties agree that where the Company or any of its Subsidiaries are admitted to participate in a Retained DC Plan with effect on and from the Closing Date in respect of the Company Employees the Company or any of its Subsidiaries, as applicable, shall pay such contributions to the relevant Retained DC Plan representing contributions made by or on behalf of the Company Employees and shall pay any expenses to such plan on the same basis that applies to other participating employers from time to time.

(f) Liabilities for Retained Plans in which the Company does not participate post Closing. The Parties agree that where the Company or any of its Subsidiaries do not participate in the Retained Plans on and from the Closing Date the sponsorship, obligations, and pre-Closing liabilities in respect of such plan will be retained by the relevant Parent or any of its Affiliates by operation of Applicable Law or by the transactions contemplated by this Agreement. Each Parent, as applicable, shall take all appropriate and necessary actions to effectuate the foregoing.

Section 8.05 Allocation of Risk Benefit Liabilities. The Parties agree that if a liability or cost attributable to a Risk Plan or a workers compensation claim is attributable to a single event, a series of events, or a prolonged event that occurs only prior to the Closing Date, then the applicable Parent or any of its applicable Affiliates (other than the Company and its Subsidiaries) shall be responsible for that liability or cost even if the claim is filed post-Closing. The Parties agree that if a liability or cost attributable to a Risk Plan or a workers compensation claim is attributable to a series of events or a prolonged event covering both the pre-Closing and post-Closing period, the Company and any of its Subsidiaries shall be responsible for such liability or cost. Moreover, the Company and any of its Subsidiaries shall be responsible for the liabilities or costs in respect of the Risk Plans and workers compensation claims attributable to a single event that occurs on or after the Closing Date.

Section 8.06 Employees Consultation and Notification. Prior to the Closing Date, Owens Corning and its Subsidiaries shall, and shall cause its respective managers, agents and

representatives to, comply with all requirements under applicable labor and employment Laws of the applicable jurisdictions and any collective bargaining agreements applicable to the employees of Owens Corning’s Business to inform, and/or consult with, the relevant unions and local works councils of Owens Corning and its Subsidiaries and to satisfy other employees’ or employee representatives’ consultation or notification requirements, in each case in connection with the transaction contemplated hereby. Prior to the Closing Date, Saint-Gobain and its Subsidiaries shall, and shall cause their respective managers, agents and representatives to, comply with all requirements under applicable labor and employment Laws of the applicable jurisdictions and any collective bargaining agreements applicable to employees of Saint-Gobain’s Business to inform, and/or consult with, the relevant unions and local works councils of Saint-Gobain and its Subsidiaries and to satisfy other employees’ or employee representatives’ consultation or notification requirements, in each case in connection with the transaction contemplated hereby. Prior to the Closing Date, Owens Corning and Saint-Gobain and their respective Subsidiaries shall reasonably cooperate with each other with respect to the provision of information required or desired to be provided in connection with such information and consultation formalities, and the Parties shall provide each other with a reasonable opportunity to review and comment on any proposed information supplied and to approve any proposed reference to the Company and/or its business plan. With respect to any notices, consultations, and payments relating to events occurring prior to the Closing Date, the respective Parties shall be responsible for and assume all liability for any and all notices, consultations, payments, fines or assessments due to any Governmental Authority, employees or otherwise, relating to the employment, discharge, or layoff of employees of the respective Parties before the Closing Date. Likewise, with respect to any notices, consultations, and payments related to events occurring on or after the Closing Date, the Company and its Subsidiaries shall be responsible for and assume all liability for any and all notices, consultations, payments, fines or assessments due to any Governmental Authority, employees or otherwise, relating to the employment, discharge, or layoff of Company Employees of the Company and its Subsidiaries on or after the Closing Date.

Section 8.07 Cooperation and Assistance.

(a) Cooperation of the Company. On and after the Closing Date, the Company shall, and shall cause its Subsidiaries to, cooperate with the Parents to provide, to the extent permitted by Applicable Laws, such current information regarding the Company Employees and former OC Employees and SG Employees on an ongoing basis as may be reasonably necessary to facilitate determinations of eligibility for, and payments of benefits to, the Company Employees under the Parent Plans.

(b) Cooperation of Parents. On and after the Closing Date, the Parents shall, and shall cause their Affiliates to, cooperate with the Company to provide, to the extent permitted by Applicable Laws, such current information regarding the Company Employees, Inactive Employees and former OC Employees and SG Employees on an ongoing basis as may be reasonably necessary to facilitate determinations of eligibility for, and payments of benefits to, the Company Employees under the employee benefit plans of the Company and its Subsidiaries.

reasonably necessary or legally required provision of information to, or consultations, discussions or negotiations with, employee representative bodies (including any unions or works councils) which represent employees affected by the transactions contemplated by this Agreement.

Section 8.08 Seconded Employees. Each Parent shall, and shall cause its respective Affiliates to, take all necessary steps to ensure that the secondment agreements or arrangements in respect of any employees seconded to either or both of them and assigned to the Business, can lawfully, and without violating such secondment agreements or arrangements, be transferred or assigned to the Company or its Subsidiaries. In the event that the consent of a third party shall be necessary for the transfer or assignment of any such secondment agreement or arrangement to the Company or its Subsidiaries, the applicable Parent or its applicable Affiliates shall secure such consent or obtain a waiver of the requirement for such consent. Each Parent shall, and shall cause its respective Affiliates to ensure that no secondment agreement or arrangement transferred to the Company or its Subsidiaries shall be terminated or cancelled by the Parent or relevant Affiliate, unless otherwise expressly agreed to in writing by the Company or its Subsidiaries.

Section 8.09 Layoffs. From the date of this agreement until the Closing Date, the Parents shall not, and shall cause their respective Affiliates not to, take any action affecting more than fifty employees engaged in the Business, respectively, that would constitute a mass layoff, a mass termination, or a plant closing and which would trigger notice requirements or liability under any Applicable Law concerning reductions in force or any similar law, in any of the applicable jurisdictions.

resulting from or relating to the Business (but only to the extent conducted on or after the Closing Date or (vi) any breach of the covenant set forth in Section 5.10 (s)).

Section 11.03 Procedures.

(a) If any Party or any of the Parties’ respective Affiliates or Representatives shall seek indemnification pursuant to Section 11.02, the Person seeking indemnification (the “Indemnified Party”) shall give written notice to the Party from whom such indemnification is sought (the “Indemnifying Party”) promptly (and in any event within 30 days) after the Indemnified Party (or, if the Indemnified Party is a corporation, any officer or director of the Indemnified Party) becomes aware of the facts giving rise to such claim for indemnification (an “Indemnified Claim”) specifying in reasonable detail the factual basis of the Indemnified Claim, stating the amount of the Damages, if known, the method of computation thereof, containing a reference to the provision of this Agreement in respect of which such Indemnified Claim arises and demanding indemnification therefor. The failure of an Indemnified Party to provide notice in accordance with this Section 11.03, or any delay in providing such notice, shall not constitute a waiver of that Party’s claims to indemnification pursuant to Section 11.02, except to the extent that (i) any such failure or delay in giving notice causes the amounts paid or to be paid by the Indemnifying Party to be greater than they otherwise would have been or otherwise results in prejudice to the Indemnifying Party or (ii) such notice is not delivered to the Indemnifying Party prior to the expiration of the applicable survival period set forth in Section 11.01. If the Indemnified Claim arises from the assertion of any claim, or the commencement of any suit, action, proceeding or Remedial Action brought by a Person that is not a Party hereto (a “Third Party Claim”), any such notice to the Indemnifying Party shall be accompanied by a copy of any papers theretofore served on or delivered to the Indemnified Party in connection with such Third Party Claim.

(b) Upon receipt of notice of a Third Party Claim from an Indemnified Party pursuant to Section 11.03(a), the Indemnifying Party shall be entitled to assume the defense and control of such Third Party Claim subject to the provisions of this Section 11.03 by providing notice of such election to the Indemnified Party within 30 days of its receipt of notice of such Third Party Claim; provided, that any such assumption of the defense and control of a Third Party Claim shall constitute an acknowledgement and acceptance by the Indemnifying Party of its obligation to indemnify the Indemnified Party for all Damages arising out of such Third Party Claim under this Article XI. If the Indemnifying Party elects to assume the defense of a Third Party Claim, the Indemnifying Party will not be liable to the Indemnified Party for any legal or other expenses subsequently incurred by the Indemnified Party in connection with the defense thereof as long as the Indemnifying Party is conducting its defense in accordance with this Section 11.03(b); provided, that if in the written opinion of counsel to any Indemnified Party a conflict of interest exists in respect of such claim, such Indemnified Party will have the right to employ separate counsel reasonably satisfactory to the Indemnifying Party to represent such Indemnified Party and in that event the reasonable fees and expenses of such separate counsel will be paid by the Indemnifying Party; provided that in the event there are multiple Indemnified Parties, the Indemnifying Party shall only have an obligation to pay the fees and expenses of one separate counsel for all Indemnified Parties. If the Indemnifying Party does not assume the defense and control of a Third Party Claim within such 30 day period, the Indemnified Party shall have the right to defend such Third Party Claim in such manner as it may deem appropriate

and the Indemnifying Party shall be liable for all Damages arising out of such Third Party Claim, to the extent that such Damages are subject to indemnification by the Indemnifying Party hereunder, and shall promptly pay or reimburse the Indemnified Party for all reasonable fees and expenses incurred in the defense by the Indemnified Party of such Third Party Claim. Whether the Indemnifying Party or the Indemnified Party is defending and controlling any such Third Party Claim, it shall select counsel, contractors, experts and consultants of recognized standing and competence, shall take all steps necessary in the investigation, defense or settlement thereof, and shall at all times diligently and promptly pursue the resolution thereof. The Party conducting the defense thereof shall at all times act as if all Damages relating to the Third Party Claim were for its own account and shall act in good faith and with reasonable prudence to minimize Damages therefrom. Each of the Indemnified Party and the Indemnifying Party shall, and shall cause each of its respective Affiliates and Representatives to, reasonably cooperate with the other in connection with any Third Party Claim at the request of the other and at the expense of the Indemnifying Party. In addition, the Party not conducting the defense shall have the right to participate in the defense of such Third Party Claim at its own expense.

(c) The Indemnifying Party shall be authorized to consent to a settlement of, or the entry of any judgment arising from, any Third Party Claims, and the Indemnified Party shall consent to a settlement of, or the entry of any judgment arising from, such Third Party Claims if (i) the Indemnifying Party shall pay or cause to be paid all amounts arising out of such settlement or judgment concurrently with the effectiveness thereof, (ii) such settlement shall not encumber any of the assets of the Indemnified Party or contain any restriction or condition that would apply to such Indemnified Party or to the conduct of that Party’s business, (iii) such settlement contains as a condition thereto a complete and unconditional release of the Indemnified Party, and (iv) such settlement does not contain any admission of wrongdoing by the Indemnified Party. Except for the foregoing, no settlement or entry of judgment in respect of any Third Party Claim shall be consented to by any Indemnifying Party without the express written consent of the Indemnified Party, which consent shall not be unreasonably withheld or delayed. Whether or not the Indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party will not consent to a settlement of, or the entry of any judgment arising from, a Third Party Claim without the express written consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed.

(d) If an Indemnifying Party makes any payment on an Indemnified Claim, the Indemnifying Party shall be subrogated, to the extent of such payment, to all rights and remedies of the Indemnified Party to any insurance benefits or other claims or benefits of the Indemnified Party with respect to such claim. Such Indemnified Party will cooperate with the Indemnifying Party in a reasonable manner, at the cost and expense of such Indemnifying Party, in prosecuting any subrogated right or claim.

(e) In the event that a Company Indemnified Party is the Indemnified Party, the Parent that is not the Indemnifying Party may elect to assert the Indemnified Claim on behalf of the Company Indemnified Party and each of the Company Indemnified Party and such Parent shall be deemed an Indemnified Party for purposes of the procedural provisions of this Section 11.03. In such event, the Company Indemnified Party shall reasonably cooperate with the Parent deemed an Indemnified Party, which Parent shall control the pursuit of the Indemnified Claim and shall do so in good faith and in a manner reasonably believed to be in the best interests of the

Company Indemnified Party. If and to the extent that the Indemnifying Party is successful in the defense of any such Indemnified Claim, the Parent asserting the Indemnified Claim on behalf of the Company Indemnified Party will promptly reimburse the Indemnifying Party for its reasonable fees and expenses incurred in the defense of the Indemnified Claim.

Section 13.14 Dispute Resolution

In the event that there are more than two Parties to a Dispute, the arbitrators shall be appointed in accordance with the ICC Rules. All submissions and awards in relation to arbitration under this Agreement shall

be made in English and all arbitration proceedings and all pleadings shall be in English. For purposes of this Section 13.14(b), the term “Party to a Dispute” may include groups of aligned Parties.

(c) Except as may be required by applicable law, stock exchange rules, Governmental Authorities, or in connection with the ordinary course operation of the Business, the Parties agree to maintain confidentiality as to all aspects of the arbitration, including its existence and results, except that nothing herein shall prevent any Party from disclosing information regarding the arbitration for purposes of enforcing the judgment of the arbitral tribunal or the expert arbitrator or in any court proceedings involving the Parties. The Parties further agree to obtain the arbitral tribunal’s agreement to preserve the confidentiality of the arbitration.

Section 13.15 Consequential Damages. Notwithstanding any other provision of this Agreement or any other Transaction Document to the contrary, no Party shall be liable to any other Party (or its Affiliates) for special, indirect, punitive or consequential damages, including lost profits and opportunity costs (except in each case to the extent assessed in connection with claims by other Persons), resulting from or arising out of a breach of this Agreement or any other Transaction Document (except where such breach is a result of fraud or gross negligence of such Party).

Section 13.16 Performance. Each Party will cause to be performed and hereby guarantees the performance of all actions, agreements and obligations set forth herein to be performed by any Subsidiary of such Party.

(b) Section 6.1(a) shall not apply to any business owned as of the date hereof by either an SG Party or an OC Party that the Parties have agreed shall not be contributed to the Joint Venture (including, for the avoidance of doubt, to the SG Textile Solutions Business), provided, however, that any such business shall not manufacture or sell any Company Products (as defined in the Master Contribution Agreement) except pursuant to a written supply, license, and/or tolling agreement with the Company or its Affiliates.

(c) Section 6.1(a) shall not prohibit the acquisition, directly or indirectly, by either Party or any of its Affiliates, of any business assets or shares which cause it to be in breach of Section 6.1(a) (the “Prohibited Asset”) as the result of the consummation of any merger, acquisition or similar transaction for so long as and provided that (i) the annual sales revenue generated by the Prohibited Asset represents less than ten (10) percent of the total annual sales revenue generated by such acquired business assets or shares, or (ii) the annual sales revenue generated by the Prohibited Asset is less than USD twenty (20) million, in each case calculated based on the relevant annual financial statements for the most recent complete financial year.

(d) If either Party or any of its Affiliates becomes the owner of any Prohibited Asset at any time such Party or any of its Affiliates is a Shareholder, such Party shall Transfer or cause its Affiliate to Transfer such Prohibited Asset to a Third Party for cash consideration only and shall use its reasonable efforts to effect such Transfer within twelve (12) months after its acquisition (and if such Transfer does not occur within such twelve (12) month period, such Party shall continue to use its reasonable efforts to effect such Transfer as soon as practically possible), which Transfer will be subject, however, to a right of first refusal in favor of the Company or any Joint Venture Entity designated by the Company, which right of first refusal shall be exercised in accordance with Section 6.1(e).

If the Company either fails to give the ROFR Notice within such sixty (60) day period or notifies the Transferor that it does not wish to purchase the Prohibited Asset, the Company shall be deemed to have declined to purchase such Prohibited Asset and the Transferor may thereafter transfer, or have its Affiliate transfer, to the proposed transferee identified in the Transferor’s Notice at any time within thirty (30) days after (i) receipt of all necessary approvals from any Governmental Authority or (ii) if no such approvals are necessary, after the expiration of such sixty (60) day period, all (but not less than all) of the Prohibited Asset at a price and on terms and conditions which are not more favorable to the proposed transferee than those set forth in the Transferor’s Notice; provided that if the Prohibited Asset is not transferred to the proposed transferee for any reason within such period, then such Prohibited Asset may be transferred only by again complying with all of the terms and procedures set forth in this Section 6.1. If the Company does provide an ROFR Notice to the Transferor within such sixty (60) day period, such ROFR Notice shall be deemed to create a binding agreement between the Transferor or its applicable Affiliate and the Company (or the applicable Joint Venture Entity designated by the Company in the ROFR Notice) to Transfer, subject to the receipt of the purchase price all and not less than all of the Prohibited Asset at the price and on the other terms and conditions set forth in the Transferor’s Notice. The Transferor or its applicable Affiliate shall be liable for the Transfer of full and unencumbered legal title to the Prohibited Asset. The closing for the Transfer to the Company or the designated Joint Venture Entity shall take place at a time and place reasonably acceptable to the Transferor or its applicable Affiliate and the Company or the designated Joint Venture Entity; provided that such closing shall occur on the later of (i) thirty (30) days after the receipt of all necessary approvals from any Governmental Authority and (ii) one hundred and eighty (180) days after receipt by the Transferor of the ROFR Notice.

(g) Promptly but no later than twenty (20) Business Days following the acquisition of the Prohibited Asset by the acquiring Party or any of its Affiliates, such Party (the “ROFO Transferor”) shall give written notice (a “ROFO Transferor’s Notice”) to the Company with a copy to the other Party of its intention, or that of its applicable Affiliate, to sell the Prohibited Asset, which notice shall (i) identify the Prohibited Asset, (ii) indicate the expected purchase price of the Prohibited Asset and any other material items and conditions of the proposed Transfer and (iii) attach a copy of any due diligence report prepared by the

ROFO Transferor or its applicable Affiliate and its legal and financial advisors (but only to the extent permitted by such legal and financial advisors) for the purpose of the transaction comprising the Prohibited Asset. The date on which such ROFO Transferor’s Notice is actually received by the Company is referred to hereinafter as the “ROFO Notice Date.” The Company shall have sixty (60) days following the ROFO Notice Date to notify the ROFO Transferor in writing whether the Company (or any Joint Venture Entity) wishes to buy such Prohibited Asset on the same terms as set forth in the ROFO Transferor’s Notice (the “ROFO Notice”). If the Company either fails to give the ROFO Notice within such sixty (60) day period or notifies the ROFO Transferor that it does not wish to purchase the Prohibited Asset, the Company shall be deemed to have declined to purchase such Prohibited Asset and the ROFO Transferor or its applicable Affiliate may thereafter transfer the Prohibited Asset to any third party at a price and on terms and conditions which are not more favorable to the proposed transferee than those set forth in the ROFO Transferor’s Notice; provided that if the Prohibited Asset is not transferred for any reason before the end of a one hundred and eighty (180) day period following the expiry of the above-mentioned sixty (60) day period (or, if applicable, within thirty (30) days after receipt of all necessary approvals from any Governmental Authority, provided a binding agreement (subject only to customary conditions, including regulatory approvals) shall have been entered into between the ROFO Transferor or its applicable Affiliate and the relevant Third Party purchaser before the end of the above-mentioned one hundred and eighty (180) day period), then such Prohibited Asset may be transferred only by again complying with all of the terms and procedures set forth in this Section 6.1. If the Company does provide a ROFO Notice to the ROFO Transferor within such sixty (60) day period, such ROFO Notice shall be deemed to create a binding agreement between the ROFO Transferor or its applicable Affiliate and the Company (or the applicable Joint Venture Entity designated by the Company in the ROFO Notice) to Transfer, subject to the receipt of the purchase price, all and not less than all of the Prohibited Asset at the price and on the other terms and conditions set forth in the ROFO Transferor’s Notice. The ROFO Transferor or its applicable Affiliate shall be liable for the Transfer of full and unencumbered legal title to the Prohibited Asset. The closing for the Transfer to the Company or the designated Joint Venture Entity shall take place at a time and place reasonably acceptable to the Transferor or its applicable Affiliate and the Company or the designated Joint Venture Entity; provided that such closing shall occur on the later of (i) thirty (30) days after the receipt of all necessary approvals from any Governmental Authority and (ii) one hundred and eighty (180) days after receipt by the Transferor of the ROFO Notice.

or her employment relationship with the relevant Joint Venture Entity; provided, however, that the foregoing shall not apply to any JV Employee hired as a result of the use of an independent employment agency (so long as the agency was not directed to solicit a particular individual or a class of individuals that could only be satisfied by employees of the Joint Venture) or as a result of the use of advertisements and other general solicitation (such as an advertisement in newspapers, on either Party’s websites or internet job sites, or on radio or television) not specifically directed to JV Employees.

In the event any Party or Joint Venture Entity is requested or required (by oral or written request for information or documents in any legal proceeding, interrogatory, subpoena, civil investigative demand or similar process or by applicable Law) to disclose any such confidential or proprietary information, then such Party shall notify the other Party or the Company, or the Company will notify both Parties, as applicable, promptly of the request or requirement so that the other Party, the Parties or the Company, as applicable, at their own expense, may seek an appropriate protective order or waive compliance with this Section 6.3. If, in the absence of a protective order or receipt of a waiver hereunder, a Party or a Joint Venture Entity is, on the advice of counsel, compelled to disclose such confidential information, such Party or Joint Venture Entity may so disclose the confidential or proprietary information; provided that such Party or Joint Venture Entity shall use reasonable efforts to obtain reliable assurance that confidential treatment shall be accorded to such confidential or proprietary information.

3.4 Option Exercise Procedure

(a) Annually, together with the preparation of the annual financial statements of the Company for the relevant Fiscal Year, the Parties shall cause the Company to (i) prepare a statement setting forth, in reasonable detail, the Company’s calculation of the Exit Price and the Management Company Price as of the end of the relevant Fiscal Year as if such date was the End Date (based, to the extent available, on audited financial statements), (ii) obtain a statement of confirmation of such calculation from the JV Auditors and (iii) send such statement to the Parties, together with the JV Auditors’ statement of confirmation and the underlying audited financial statements if applicable, no later than March 31 following the end of the relevant Fiscal Year.

(b) Each of OC Topco and SG Parent shall have the right, but not the obligation, to exercise its respective applicable Option during the relevant time period set forth in this Option Agreement by delivering a written notice (the “Option Exercise Notice”) to the other party, indicating its exercise of such right, which notice shall be irrevocable. A copy of such notice shall also be sent to the Company.

(c) The Option Exercise Notice shall be effective if delivered to the relevant party in accordance with Section 6.1 of this Option Agreement within the time period specified in Sections 3.1(a), 3.2(a), 3.3(c) and 3.3(d), as applicable.

(d) (1) To the extent that the Option Exercise Notice is made on a date other than any date during the first quarter of any Fiscal Year or December 31, the Parties shall cause the Company to (i) prepare a statement setting forth, in reasonable detail, the Company’s calculation of the Exit Price (including the performance premium, if applicable) and the Management Company Price for the relevant period (based, to the extent available, on audited financial statements), (ii) obtain a statement of confirmation of such calculation from the JV Auditors and (iii) send such information to OC Topco and SG Parent, together with the JV Auditors’ statement of confirmation, and the audited financial statements if available, no later than sixty (60) days after the Option Exercise Notice. (2) In addition, in the event of an Option Exercise Notice, SG Parent shall (i) prepare an audited balance sheet of SG Topco as of the End Date, using French GAAP, (ii) based on such balance sheet, prepare a statement setting forth, in reasonable detail, an estimate of the calculation of the Target Price as of the Exit Date (taking into account the uncertainty as to the Exit Date), and (iii) send such information and the underlying audited financial statements to OC Topco no later than sixty (60) days after the Option Exercise Notice. Twenty (20) days before the Exit Date, SG Parent shall provide an updated estimate of the Target Price as of the Exit Date, which estimate will be used as the Target Price paid on the Exit Date, subject to Section 3.5. Furthermore, if there is a SG Excess Shareholder Loan, the Parents shall cause the loan payable to the Company (together with the accrued interests thereon) to be converted by the Company into capital of SG Topco immediately prior to the Exit Date.

(e) (1) Unless either OC Topco or SG Parent notifies the other within

forty-five (45) days after receipt from the Company of the statements delivered annually set forth in Section 3.4(a) of any specific objections to paragraph (A) of the Exit Price, neither OC Topco or SG Parent shall be entitled to contest any component of paragraph (A) of the Exit Price for any Fiscal Year for which no specific objection has been notified. In case either OC Topco or SG Parent notifies the other party of any specific objections to the statements delivered in accordance with Section 3.4(a) within forty-five (45) days after receipt of the relevant statement (which notice must set forth such objecting party’s determination of the value for such item), the parties shall attempt to settle such objections within fifteen (15) days from the receipt of the notice of objection. (2) In case either OC Topco or SG Parent notifies the other party of any specific objections to the statements delivered in accordance with Section 3.4(d) within forty-five (45) days after receipt of the statements delivered in accordance with Section 3.4(d) (which notice must set forth such objecting party’s determination of the value for such item), the parties shall attempt to settle such objections within fifteen (15) days from the receipt of the notice of objection; it being understood that neither party shall be entitled to object to any component of paragraph (A) of the Exit Price for any Fiscal Year which was finally determined in accordance with Section 3.4(e)(1). (3) If OC Topco and SG Parent are unable to reach agreement within such periods set forth above, only those matters specifically objected to shall be submitted to and decided by Grant Thornton, London Office, or in the event Grant Thornton, London Office is conflicted, an internationally known independent accounting firm (the “Unaffiliated Firm”), at the request of either party. The Unaffiliated Firm shall only consider the matters in dispute and all other matters shall be deemed finally resolved. Each party to the dispute must provide the Unaffiliated Firm in writing its determination of the value of each of the matters in dispute within five (5) days after the Unaffiliated Firm is commissioned. The Unaffiliated Firm shall give both parties the opportunity to present their arguments in writing and shall make its determinations promptly by delivering to OC Topco and SG Parent its determination of the Exit Price, including the performance premium, if applicable, the Management Company Price and/or the Target Price, as applicable, within thirty (30) days after its commissioning by either party. The Unaffiliated Firm’s determinations shall, in the absence of manifest error, be final and binding upon OC Topco and SG Parent. The fees and expenses, if any, of the Unaffiliated Firm shall be shared by OC Topco and SG Parent in inverse proportion to their respective success on the merits and such allocation of fees and expenses shall be calculated by the Unaffiliated Firm and shall be conclusive and binding on the parties. Each party shall otherwise bear its own fees and expenses.

(f) SG Parent shall make available to OC Topco and its advisors and, upon reasonable request, to the Unaffiliated Firm, the books, records, documents and work papers underlying the preparation of the documents referred to in the second sentence of Section 3.4(d). In addition, the Parties shall cause the Company and the Management Company to make available to OC Topco and SG Parent and their advisors and, upon reasonable request, to the Unaffiliated Firm, the books, records, documents and work papers underlying the preparation of the documents referred to in Section 3.4(a) and in the first sentence of Section 3.4(d).

(g) The transfer of all of SG Parent’s Ownership Interests in SG Topco, and payment therefor by OC Topco or its designee(s), shall take place (A) in the case of the exercise by OC Topco of its Call Option or Change of Control Call Option, (i) thirty (30) days after the Exit Price, including the performance premium, if applicable, the Management Company Price and the Target Price shall have been determined in accordance with the

provisions of this Section 3.4, or (ii) thirty (30) days after receipt of all necessary regulatory approvals, whichever is later, and (B) in the case of the exercise by SG Parent of its Put Option or Change of Control Put Option, (i) forty-five (45) days after the Exit Price, including the performance premium, if applicable, the Management Company Price and the Target Price shall have been determined in accordance with the provisions of this Section 3.4, (ii) thirty (30) days after receipt of all necessary regulatory approvals, or (iii) one-hundred eighty (180) days after the Option Exercise Notice, whichever is later, in each case at the registered office of the Company or such other place as shall have been agreed between the Parties (the day on which the closing of such transaction takes place, the “Exit Date”). The purchase price shall be paid in USD and shall bear interest calculated daily from the End Date to the date of payment, at the Interest Rate. SG Parent shall deliver to OC Topco (A) with respect to SG Topco, (i) the register of share transfers (“registre des mouvements de titres”) and the individual shareholder accounts (“fiches individuelles d’actionnaires”) on which the sale of the Ownership Interests shall have been duly registered, (ii) a duly completed and executed tax form (“CERFA form 2759”) required in order to register the transfer of the Ownership Interests with the French tax authorities, (B) unconditional resignation letters, effective on the date of transfer, of the directors and corporate officers of SG Topco, and of the directors of the Company and the Management Company designated by SG Parent and (C) any other documents necessary for completion of the sale of the Ownership Interests in SG Topco.

(h) If the transfer of the Ownership Interests in SG Topco pursuant to an Option is subject to the approval of an administrative, regulatory or governmental authority, the Parties agree to use reasonable efforts to agree to reasonable commitments or undertakings that such authority may require from the Parties or the Company as a condition to the authorization of such transfer; provided however that OC Topco and its Affiliates shall in no event be required to agree to any commitments or undertakings that impact to any significant extent the value for them of the contemplated transaction.

(i) If either (A) SG Parent is no longer the sole shareholder of SG Topco (except as contemplated in the last sentence of Section 3.4(d)), (B) SG Topco or its Affiliates have breached Section 2.4(a) in any material respect, (C) SG Topco has, as of the Exit Date, any outstanding material debts or liabilities other than those permitted liabilities under Section 2.5 or (D) the Ownership Interests held by SG Parent in SG Topco are not free and clear of all rights of pledges, liens, options or other encumbrances as of the Exit Date, then OC Topco shall have the option to purchase the Ownership Interests owned by SG Topco in the Company and the Management Company instead of the Ownership Interests owned by SG Parent in SG Topco, for the same consideration less the Target Price, and SG Topco hereby grants such option right to OC Topco. In the event OC Topco exercises such option right, (i) if there are any SG Shortfall Shareholder Loans, SG Topco shall, together with its Ownership Interests in the Company and the Management Company, transfer, for no additional consideration, all rights and interests in such SG Shortfall Shareholder Loans (including the accrued unpaid interest thereon through the Exit Date), if any and (ii) if there is a SG Excess Shareholder Loan, SG Topco shall repay the SG Excess Shareholder Loan (including the accrued unpaid interest thereon through the Exit Date), in which case, the Exit Price shall be increased by the amount of such SG Excess Shareholder Loan (including the accrued unpaid interest thereon through the Exit Date). The relevant provisions of this Article III shall be read in such a case as referring to the Ownership Interests of the Company and the Management Company rather than the Ownership Interests of SG Topco.

(j) To the extent that, in the twelve (12) month period following the End Date, the Joint Venture receives any indemnification payments pursuant to the indemnification provisions of the Master Contribution Agreement for extraordinary events (per U.S. GAAP) that reduced the Exit Price, OC Topco shall, within thirty (30) days after the receipt by the Joint Venture of any such payments, pay to SG Parent the product of (i) 0.4 and (ii) the amount of such indemnification payments.

3.5 Indemnity. SG Parent shall indemnify OC Parent and its Affiliates fully against, and agrees to defend and hold them harmless from, any and all losses, damages, costs and expenses incurred by any of them, upon acquisition of the Ownership Interests in SG Topco, resulting from (i) the legal title to the Ownership Interests purchased in SG Topco, the Company and the Management Company being defective or encumbered and (ii) any liability, actual or contingent, present or future, liquidated or not, in SG Topco not having been taken into account in the determination of the Target Price. This Section 3.5 shall survive the termination of this Option Agreement indefinitely.

3.6 Joint and several liability (obligation solidaire).

(a) OC Topco and OC Parent will be jointly and severally liable (obligation solidaire) for any obligation of OC Topco under this Option Agreement.

(b) SG Topco and SG Parent will be jointly and severally liable (obligation solidaire) for any obligation of SG Topco under this Option Agreement.

Owens Corning Reports Record Sales of $6.5 Billion in 2006;

Company Announces Share Buy-Back Program; Strategic Review

of Siding Solutions Business and Fabwel Unit

TOLEDO, Ohio – Feb. 21, 2007 – Owens Corning (NYSE:OC) today reported record consolidated net sales of $6.461 billion in 2006, compared with $6.323 billion in 2005, a 2.2 percent increase. During the fourth quarter of 2006, the company recorded sales of $1.477 billion, compared with record sales of $1.713 billion during the same period in 2005. Fourth quarter sales declined 13.8 percent, reflecting continued weakness in U.S. housing starts and a lack of storm-related demand for roofing products.

“2006 was a year of accomplishments,” said Dave Brown, president and chief executive officer. “Owens Corning emerged from asbestos-related Chapter 11 with a strong balance sheet that positions the company to succeed through a challenging cyclical downturn of housing starts. We generated sales in 2006 that were the highest in our company’s history. During the fourth quarter, we demonstrated the strength of our business portfolio with solid results in Composite Solutions to help offset weakness in our Roofing and Asphalt segment.

“We’ve taken decisive action to position Owens Corning to generate improved value for our shareholders,” said Brown. “Yesterday, we announced that we have signed a joint-venture agreement with Saint-Gobain that will accelerate the growth of our Composite Solutions business around the world. We also are announcing today that we are evaluating strategic alternatives for our Siding Solutions business and Fabwel, a unit of our Composites organization. In addition to our strong balance sheet, our business forecast for 2007 gives us confidence in our cash generation ability. We are pleased that our Board of Directors has authorized a share buy-back program that delivers on our commitment to building shareholder value.”

As a result of the application of Fresh Start Accounting on Oct. 31, 2006, and in accordance with SOP 90-7, the post-emergence financial results of the company for the period starting Nov. 1, 2006 are presented as the “Successor” and the pre-emergence financial results of the company for the periods ending on or prior to Oct. 31, 2006 are presented as the “Predecessor.” GAAP financial statements do not straddle the Effective Date because, in effect, the Successor represents a new entity. For the readers’ convenience in this financial news release, the Successor two months ended Dec. 31, 2006 and the Predecessor ten months ended Oct. 31, 2006 have been combined and are collectively referred to as “Fiscal 2006.” The Successor two months ended Dec. 31, 2006 and the Predecessor one month ended Oct. 31, 2006 have been combined and are collectively referred to as “Fiscal fourth quarter of 2006.”

When reviewing the operating performance of the company with its Board of Directors and employees, management uses adjusted income from operations. To calculate adjusted income from operations, management excludes from net income and income from operations certain items, including those related to the company’s Chapter 11 proceedings, asbestos liabilities, restructuring and other activities and the impact of Fresh Start Accounting, so as to improve comparability over time (the “Comparability Items”). As described more fully in the attached financial schedules, such Comparability Items amounted to charges of $136 million in Fiscal 2006, $4.287 billion in 2005, and $152 million in the Fiscal fourth quarter of 2006, and a credit of $81 million in the fourth quarter of 2005.

Consolidated 2006 and Fourth-Quarter Results

•

Reported income from operations in Fiscal 2006 was $433 million, compared with a loss of $3.743 billion in 2005. Excluding the Comparability Items, Fiscal 2006 adjusted income from operations was $569 million, compared with $544 million in 2005, an increase of 4.6 percent.

•

For the Fiscal fourth quarter of 2006, reported income from operations was a loss of $9 million, compared to income of $230 million in 2005. Excluding the Comparability Items, adjusted income from operations for the Fiscal fourth quarter of 2006 was $143 million, compared with $149 million for the same period of 2005, a decrease of 4.0 percent.

•

In the second half of Fiscal 2006, restructuring and other charges were taken to realign production capacity with projected demand, exit non-core businesses, combine distribution facilities, and reduce selling, general and administrative expenses. The restructuring charges and other actions taken totaled $55 million. The expected annual improvement in operating results related to these actions is approximately $44 million.

•

Gross margin as a percentage of consolidated net sales, excluding charges related to the adoption of Fresh Start Accounting and other restructuring charges that together totaled $63 million, was 17.5 percent in Fiscal 2006 compared to 18.3 percent in 2005, a decrease of 0.8 percent.

•

Selling, General and Administrative (SG&A) expenses, as a percentage of consolidated net sales, were 8.3 percent for Fiscal 2006, compared with 8.9 percent in 2005. This improvement in productivity was primarily due to increased net sales and lower performance-based compensation.

Business Highlights:

•

2006 was the safest year in Owens Corning’s history. The company’s continued focus on employee safety resulted in a 13 percent reduction in the number of injuries compared with 2005.

•

The Insulating Systems segment introduced marketing programs to promote the sale of insulation as an energy conservation and noise-reduction solution. A first-time program called R’s on Us™ provides pricing incentives that encourage builders to increase the R-value of insulation in new homes to promote energy efficiency.

•

The Roofing and Asphalt segment completed market testing and began a national roll-out of the new and innovative Duration^TM Series roofing shingle with SureNail^® technology. This installer-friendly product features a fast-install extra-wide nailing zone and improved wind performance.

•

Owens Corning took aggressive steps within the Other Building Materials & Services segment to improve operating performance. Owens Corning is announcing today that it is exploring strategic alternatives for the Siding Solutions business, which includes its vinyl siding manufacturing operations and Norandex/Reynolds distribution business. Additionally, Owens Corning exited the HOMExperts business in December of 2006 to focus on growing its services business through franchising. The company’s manufactured stone veneer business also completed the integration of Modulo/Parmur, a previously announced European acquisition.

•

The Composite Solutions segment showed improvement throughout 2006 and finished the year with strong performance. A major milestone in the proposed global joint venture with Saint-Gobain was announced yesterday with the signing of a joint-venture agreement. This transaction is intended to deliver increased customer value through improved regional and global reach in our Composite Solutions business. Owens Corning is exploring strategic alternatives for its Fabwel unit, which produces and fabricates composite components and sidewalls for recreational vehicles and cargo trailers.

Update: Proposed Owens Corning and Saint-Gobain Joint Venture

On July 27, 2006, Owens Corning and Saint-Gobain announced that they were in discussions to merge their respective reinforcements and composites businesses, thereby creating a global company in reinforcements and composite fabrics products with worldwide revenues of approximately $1.8 billion (€1.5 billion) and 10,000 employees. The parties announced yesterday that they have signed a joint-venture agreement to merge those businesses to form a new company that will be named “OCV Reinforcements” that will serve customers with improved technology, an expanded product range and a strengthened presence in both developed and emerging markets. The agreement contemplates that the joint venture will be owned 60 percent by Owens Corning and 40 percent by Saint-Gobain. After a minimum of four years, Saint-Gobain will have the option to sell its 40 percent stake to Owens Corning, and Owens Corning will have the option to buy Saint-Gobain’s stake in the joint venture. The transaction,

which has been approved by the Boards of Directors of both parent companies, is expected to close in mid-2007 and is subject to customary closing conditions and regulatory and antitrust approvals.

Announcing: Strategic Business Review: Siding Solutions Business & Fabwel Unit

Consistent with Owens Corning’s ongoing review of its portfolio of businesses, the company today announced that it will explore strategic alternatives for the company’s Siding Solutions business, which includes its vinyl siding manufacturing operations and Norandex/Reynolds distribution business, and the company’s Fabwel unit, the leading producer and fabricator of components and sidewalls for recreational vehicles and cargo trailers. The Siding Solutions business is the largest component of the Other Building Materials and Services segment. Fabwel is a unit within Owens Corning’s Composite Solutions segment and is separate from the company’s planned joint-venture with Saint-Gobain’s Vetrotex. The company expects a midyear completion of this process.

Announcing: Owens Corning Share Buy-Back Program

Owens Corning today announced that its Board of Directors has approved a share buy-back program under which the company is authorized to repurchase up to 5 percent of Owens Corning’s outstanding common stock. At current prices, this would represent an investment of approximately $200 million. Shares may be repurchased through open market, privately negotiated, or other transactions. The timing and actual number of shares repurchased will depend on market conditions and other factors and will be at the company’s discretion. This first-time program is intended to further promote total return and value to Owens Corning shareholders.

2007 Outlook

Based on estimates of the National Association of Home Builders (NAHB), the significant slow down in U.S. housing starts is expected to carry well into 2007. This continuing market softness will be reflected in first quarter results, which seasonally is the company’s weakest quarter. The company’s business results in the Insulating Systems and Roofing and Asphalt segments tend to lag housing starts by approximately one quarter.

Many industry and economic analysts, including the NAHB, believe that housing starts will stabilize through 2007. Although Owens Corning expects that 2007 will be a challenging year, the company expects its business results to improve throughout the year if these forecasts materialize and as seasonality in home building creates gradual improvement for our businesses.

In 2007, Owens Corning anticipates that the performance of the Insulating Systems segment will reflect on a lagged basis the trend in reported housing starts. Continued company initiatives to create demand for insulation products, including our special R’s on Us™ promotion, noise-control solutions for homes and businesses and promotion of the 2005 U.S. Energy Policy Act, should bolster this segment.

The performance of the Roofing and Asphalt segment, which significantly underperformed in the second half of 2006, is expected to improve through 2007 as the excess inventory that the industry produced, due to anticipated storm-related demand which did not materialize, is gradually reduced. Financial results for the first half of this

year are expected to be less than the record results reported in the first half of 2006, when sales in this segment were up significantly because of the carry over of demand due to the hurricanes of 2004 and 2005. Adding to the results of this segment will be the continuing roll-out of the new Owens Corning Duration™ Series Shingle.

Given the recent closure of the HOMExperts^® business, continued growth of the manufactured stone veneer business and the strategic review of Owens Corning’s Siding Solutions business, improved performance is expected in the Other Building Materials and Services segment.

Revenue and profitability growth of our Composite Solutions segment is expected in 2007. The closing of the proposed joint venture with Saint-Gobain’s Vetrotex business is planned by midyear.

Going forward, Owens Corning will continue a balanced approach to the use of free cash flow. Strong operational cash flow is intended to fuel company growth and innovation, with a focus on return on net assets. Investments in maintenance and improving existing operations are forecast to total $250 million in 2007. Depreciation and amortization for the year is estimated to total $280—290 million, compared with $278 million in Fiscal 2006.

Upon emergence and subsequent distribution of contingent stock and cash to the 524(g) Trust in January 2007, Owens Corning generated a significant U.S. Federal tax net operating loss of approximately $2.8 billion. Based on current estimates, the company believes its cash taxes will be about 10 to 15 percent of pre-tax income for the next five to seven years.

Allowing for significant uncertainty in the marketplace and based upon the NAHB’s current 2007 estimate of 1.54 million housing starts, the company projects that 2007 adjusted income from operations should exceed $415 million, not including the impact of the proposed Owens Corning – Vetrotex joint venture or other strategic organizational changes. This forecast will be updated and communicated quarterly.

2006 and Fourth-Quarter Business Segment Highlights

Insulating Systems

•

Net sales for Fiscal 2006 were $2.097 billion, a 6.1 percent increase from the 2005 level of $1.976 billion. This increase was primarily the result of the continued strong demand from the U.S. housing and remodeling markets during the first nine months of 2006, robust demand in the commercial and industrial market, and favorable pricing in major product categories, which allowed the company to recover energy, material and transportation cost increases. Slowing demand from the retail and residential construction markets became evident in the fourth quarter of 2006.

•

Net sales in the Fiscal fourth quarter of 2006 decreased 6.4 percent compared to the prior year. The decrease in net sales was primarily the result of the decline in demand in the fourth quarter of 2006, reflecting weaker housing activity compared to the fourth quarter of 2005 during which residential construction was very strong.

•

Income from operations for Fiscal 2006 was $467 million, a 10.1 percent increase from the 2005 level of $424 million. Favorable pricing and improved operating efficiencies offset inflation in raw materials, energy and labor, and approximately $6 million of additional cost, primarily depreciation and amortization, resulting from the impact of the adoption of Fresh Start Accounting.

•

Fiscal fourth quarter of 2006 income from operations decreased 16.4 percent to $107 million, compared to $128 million during the same period in 2005. Fiscal fourth quarter of 2006 results included approximately $6 million of additional cost resulting from the impact of the adoption of Fresh Start Accounting.

•

During the fourth quarter of 2006, weaker housing activity combined with seasonal slow downs resulted in production curtailments at selected Owens Corning insulation manufacturing facilities. These curtailments were expanded in the first quarter of 2007 to include the entire Candiac, Quebec facility in Canada.

Roofing and Asphalt

•

Net sales for Fiscal 2006 were $1.723 billion, a 4.6 percent decrease from the 2005 level of $1.806 billion. This decrease was primarily the result of a decline in volume related to both lower new residential construction activity and a lower level of storm-related demand, particularly in the second half of 2006. This decrease was only partially offset by price increases, which generally reflect the partial pass through of higher energy, material and transportation costs. Fiscal fourth quarter of 2006 net sales totaled $304 million, compared with $492 million in the fourth quarter of 2005.

•

Income from operations for Fiscal 2006 was $72 million, a 48.2 percent decrease from the 2005 level of $139 million. This decrease was primarily driven by lower volume resulting from declines in new construction activity, combined with the abatement of demand from 2005 hurricane damage, and the inability to achieve sufficient price increases in the second half of the year to offset significant increases in asphalt coating cost. The adoption of Fresh Start Accounting had no significant impact on income from operations.

•

Fiscal fourth quarter of 2006 income from operations was a loss of $25 million, compared to income of $34 million during the same period in 2005.

•

Production at Owens Corning’s roofing and asphalt facilities in the U.S. was significantly curtailed beginning in October 2006, bringing year-end inventories down to more acceptable levels. Production operations at the Jessup, Maryland roofing and asphalt facilities were closed in the fourth quarter of 2006.

Other Building Materials and Services

•

Net sales for Fiscal 2006 were $1.260 billion, a 2.1 percent increase from the 2005 level of $1.234 billion. This increase was primarily the result of volume growth in North American manufactured stone veneer products, and the impact of our European manufactured stone veneer acquisition in mid-2006, partially offset by lower volumes in vinyl siding products. Fiscal fourth quarter of 2006 net sales totaled $288 million, compared with $325 million in the fourth quarter of 2005.

•

Income from operations for Fiscal 2006 was $13 million, a 23.5 percent decrease from the 2005 level of $17 million. The decrease was due to losses in the HOMExperts portion of our construction services business, from which we announced our exit in the fourth quarter of 2006, and volume declines in vinyl siding products, partially offset by increased volume and production efficiencies in manufactured stone veneer products. The adoption of Fresh Start Accounting had no significant impact on income from operations.

•

Fiscal fourth quarter of 2006 income from operations decreased to breakeven, compared to $5 million of income during the same period in 2005.

•

Performance in this segment was lifted by productivity improvements within our domestic manufactured stone veneer organization and the midyear acquisition of a European producer and distributor of such products. The financial results of this acquisition are included in the Fiscal fourth quarter of 2006 reporting of this segment.

Composite Solutions

•

Net sales for Fiscal 2006 were $1.560 billion, a 4.3 percent increase from the 2005 level of $1.495 billion. The increase in sales was primarily attributable to the acquisition of a manufacturing facility in Japan from Asahi Glass Co. Ltd. during the second quarter of Fiscal 2006. Fiscal fourth quarter of 2006 net sales totaled $383 million, compared with $373 million in the fourth quarter of 2005.

•

Income from operations for Fiscal 2006 was $159 million, a 14.4 percent increase from the 2005 level of $139 million. Gains on the sale of metals used in certain production tooling accounted for $38 million of the improvement. Without these gains, income from operations would have declined by $18 million. Fiscal 2006 income from operations also included a $20 million gain related to insurance recoveries associated with the July 2005 flood of the Taloja, India manufacturing facility, and was adversely impacted by an estimated $8 million of losses due to downtime associated with a capacity expansion and recovery from the flood. The decrease in income from operations, excluding the effect of the gains on the sale of metals, the insurance recovery and the downtime costs, was due to cost inflation in raw materials and transportation. The adoption of Fresh Start Accounting had no significant impact on income from operations.

•

Fiscal fourth quarter of 2006 income from operations increased 8.9 percent to $49 million, compared to $45 million during the same period in 2005 which included a $7 million gain on the sale of metals used in certain production tooling and $4 million in costs associated with the July 2005 flood of the Taloja, India manufacturing facility.

•

During the second half of the year, results improved due to stronger volumes, improved pricing, increased manufacturing productivity (including the return to full operation of our facilities in India and Brazil), reduced operating expenses and benefits from the second quarter acquisition of reinforcement capacity in Japan.

The company continues to evaluate its tax balance sheet accounts in light of the application of Fresh Start Accounting related to emergence from Chapter 11. This review will be completed prior to the filing of the company’s annual report on Form 10-K for 2006, which is currently scheduled to occur on or about March 14, 2007. The results

of that review will not impact the operational results reported today but could result in immaterial adjustments to the company’s balance sheet.

First quarter 2007 results are currently scheduled to be announced on Wednesday, May 2, 2007.
