The Parties acknowledge that the fair market value of their combined Businesses is USD1,505,000,000 based on the Business Plan (as that term is defined in the Joint Venture Agreement) and that the value of Owens Corning’s Business and Saint-Gobain’s Business is equal to 60% and 40% of the combined value, respectively.

Section 3.04 Net Working Capital/Net Debt Amounts.

(a) Promptly following the Closing Date, but in no event later than 90 days after the Closing Date, each Parent shall, at its expense and with the assistance of the Company, prepare and submit to the Company, the other Parent and the Review Firm (i) the unaudited consolidating balance sheet of its Business to be included in the Joint Venture as of the close of business on the day prior to the Closing Date (prepared in all material respects in accordance

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.

(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).

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.

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.

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.

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,

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.

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.

Without limiting the foregoing, it is understood that except to the extent provided in this Article XI, neither Owens Corning nor Saint-Gobain shall have any liability to the other for any diminishment in value of the other’s ownership interest (or the ownership interest of the other’s Subsidiaries) in the Company as a result of any matters giving rise to a claim for indemnification under this Article XI.

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.
