 WHEREAS, at the request of Owens Corning, the Parties desire that the purchase of the Purchased Assets be

 NOW, THEREFORE, in consideration of the mutual covenants and agreements of the Parties contained herein and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the Parties agree as follows: 
 ARTICLE I 
 DEFINITIONS 
 Section 1.01
Definitions. Capitalized terms used in this Agreement shall have the meanings specified in Exhibit A or elsewhere in this Agreement. 
 ARTICLE II 
 PRE-CLOSING TRANSACTIONS 
 Section 2.01 Purchase and Sale. On the terms and subject to the conditions set forth in this Agreement, on the Closing Date, Saint-Gobain shall (or shall cause the applicable Subsidiary Transferor to)
sell, convey, assign, transfer and deliver to the applicable Purchasing Company, and Owens Corning shall (or shall cause the applicable Purchasing Company to) purchase and accept all of the right, title and interest of Saint-Gobain or such
applicable Combined Transferor in and to (i) the SG Acquired Subsidiaries (ii) the Italy Metal, (iii) the Brazil Metal and (iv) the SG Acquired Intellectual Property (collectively, the “Purchased Assets”) all as
set forth on Exhibit B attached hereto, free and clear of all Liens other than Permitted Liens. Such transfers shall occur in the order as specified on Exhibit B attached hereto. 
 Section 2.02 Purchase Price; Allocation of Purchase Price. 
 (a) The aggregate purchase price (the “Purchase Price”) for the Purchased Assets and for the covenant respecting non-competition set forth in Section 5.12 is as set forth on Exhibit B,
subject to adjustment as provided herein. Each Purchasing Company shall pay to the applicable Combined Transferor at the Closing that portion of the Purchase Price relating to each Purchased Asset as is specified under, and in the manner described
on Exhibit B attached hereto. The Purchase Price shall be paid on the Closing Date by wire transfer of immediately available funds to an account or accounts designated in writing by the applicable Subsidiary Transferor no later than
three (3) Business Days prior to the Closing Date. 
 (b) If the Closing occurs after November 1, 2007, the Purchase Price shall be
adjusted as follows to reflect fluctuations in the exchange rate (using the USD/EUR European Central Bank rate) between November 1, 2007 and the Closing Date: (i) the Purchase Price will be converted into EUR using the European Central
Bank USD/EUR exchange rate as of 

  

 2 








 
November 1, 2007 and (ii) on the Closing Date, such EUR amount shall be converted into USD using the European Central Bank USD/EUR exchange rate as
of 5:00 p.m. Central European Time on the Business Day preceding the Closing Date. The amount in USD following the application of subclauses (i) and (ii), if applicable, shall be the Purchase Price (subject to further adjustment as provided
herein). 
 (c) No less than two weeks prior to the Closing Date, Saint-Gobain shall deliver to Owens Corning the Metal Reconciliation
Certificate in respect of the Brazil Metal, the Italy Metal and all Metal owned by the SG Acquired Subsidiaries. If the aggregate SG Owned Metal Book Quantity of platinum and/or rhodium set forth on such Metal Reconciliation Certificate is less than
the Expected Book Quantity of platinum and/or rhodium (as applicable), the Purchase Price (as adjusted pursuant to paragraph (b) above, if applicable) shall be reduced by an amount equal to the Johnson Matthey Value of platinum and/or rhodium
(as applicable) on the second Business Day prior to the Closing Date multiplied by the shortfall of platinum and/or rhodium (as applicable); provided, that in lieu of a cash adjustment, Saint-Gobain and its Affiliates may physically deliver
at Closing to Owens Corning or its Subsidiaries additional platinum or rhodium to cover any shortfall of the other Metal using the Johnson Matthey Value of platinum and/or rhodium (as applicable) on the second Business Day prior to the Closing Date.

 Section 2.03 Saint-Gobain Pre-Closing Reorganization. 
 (a) Saint-Gobain shall take or cause to be taken all actions necessary to effectuate a corporate reorganization, substantially in accordance with the
steps outlined on Exhibit C attached hereto, such that immediately prior to the Closing, all SG Acquired Subsidiaries will be exclusively engaged in Saint-Gobain’s Business and all SG Employees and all SG Acquired Assets and related
SG Assumed Liabilities will be held (or employed, as applicable) by SG Acquired Subsidiaries. In connection with the foregoing, with respect to SG Acquired Assets, prior to the Closing Date, Saint-Gobain shall, and shall cause its Asset
Transferors to contribute all SG Acquired Assets located outside the United States (if any) to newly formed or existing, direct or indirect, Subsidiaries of Saint-Gobain which are or shall be SG Acquired Subsidiaries organized in the
jurisdiction of the location of such assets and which are or shall be engaged exclusively in Saint-Gobain’s Business (each such Subsidiary to be a partnership or disregarded entity for United States federal income tax purposes, except any
such Subsidiary for which an election to be so treated is not then permitted and which is subject to the procedures provided in the last sentence of Section 6.05(c) of this Agreement). In no event shall Saint-Gobain deviate from the steps
outlined on Exhibit C – part II to the extent that the aggregate affect of all such deviations shall have an adverse impact which is material on Owens Corning. 
 (b) In connection with the contribution of SG Acquired Assets described in clause (a), the applicable Subsidiaries receiving such contributions (the
“SG Reorganized Subsidiaries”) shall assume and agree to pay, satisfy and discharge the SG Assumed Liabilities exclusively related to the SG Acquired Assets it received pursuant to clause (a). 
 Section 2.04 Reorganization of SG Excluded Assets. Notwithstanding any other provision in this Agreement to the contrary, the Parties
expressly understand and agree that the 

  

 3 








 
SG Excluded Assets shall be retained by Saint-Gobain (and/or its Affiliates other than the SG Acquired Subsidiaries), as applicable, and, as
applicable, shall be excluded from the SG Acquired Assets and transferred out of the SG Acquired Subsidiaries prior to the Closing. 
 Section 2.05 Joinder of Italian Purchasing Company. Following the formation by Owens Corning of an Italian entity prior to Closing that will serve as the Purchasing Company of Reinforcement and Composites Italia Srl, such entity
shall execute a joinder to this Agreement solely in respect of the obligations set forth in Sections 2.01 and 2.02 in the form attached hereto as Exhibit D. 
 ARTICLE III 
 CLOSING 
 Section 3.01 [Intentionally Omitted.] 
 Section 3.02 Closing. (a) The closing (the “Closing”) of the Contemplated Transactions shall, unless otherwise agreed by the Parties, take place at the offices of Morgan, Lewis & Bockius LLP, 101
Park Avenue, New York, New York 10178, at 10:00 a.m. on the first day of the month following the month in which all conditions to the Closing set forth in Article X have been satisfied or waived (by the Party entitled to waive
the condition), unless all such conditions are fulfilled less than five (5) Business Days before the first day of the relevant month, in which case the Closing Date shall be the first day of the next succeeding month, unless otherwise agreed;
provided, in each case, that if such first day is not a Business Day, the Closing shall take place on the Business Day immediately following but shall be effective on such first day. The Closing will become effective at 12:01 a.m.,
New York Time on the Closing Date. 
 (b) At the Closing, the Parties shall execute and deliver, and shall cause their respective
Affiliates to execute and deliver, as applicable, the Transaction Documents. 
 Section 3.03 [Intentionally Omitted.] 

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, Saint-Gobain shall at its expense, and with the reasonable assistance and cooperation of the SG Acquired
Subsidiaries (including reasonable access to the relevant information where such information is located) during normal business hours without unreasonably interfering with the operations of the SG Acquired Subsidiaries, prepare and submit to
Owens Corning and the Review Firm (i) the unaudited consolidating balance sheet of its Business being acquired pursuant to this Agreement as of the close of business on the day prior to the Closing Date (prepared in all material respects
in accordance with IFRS, 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 IFRS, prepared in accordance with the accounting
principles, policies, practices, methods and procedures (including any procedures relating to applicable exchange rates) used in calculating Saint-Gobain’s SG Reference Date Balance Sheet) and applied on a consistent basis and (ii) a
statement setting forth, in reasonable detail, Saint-Gobain’s calculation of (x) its Net Working Capital (the 

  

 4 








 
“Proposed Adjusted Net Working Capital Amount”) and (y) its Net Debt (the “Proposed Adjusted Net Debt Amount”), in
each case as of the close of business on the day prior to the Closing Date; provided, however, that for the purpose of calculating the Proposed Adjusted Net Debt Amount, the proceeds to be received by Saint-Gobain Vetrotex France and
Saint-Gobain Vetrotex International in accordance with Exhibit B for the sale of the SG Acquired Intellectual Property and the SG Acquired Subsidiaries listed in Schedule 3.04(a) shall be taken into account in the calculation of
the Adjusted Net Debt Amount without giving effect to the reduction of any indebtedness for borrowed money resulting from the use of such proceeds and only to the extent such proceeds are not distributed to any Saint Gobain Affiliate that is not a
SG Acquired Subsidiary other than in connection with the repayment of indebtedness for borrowed money. Owens Corning shall make available to Saint-Gobain all books, records, documents and other papers of Saint-Gobain’s Business where located as
reasonably required by Saint-Gobain to prepare its calculation of the Proposed Adjusted Net Working Capital Amount and the Proposed Adjusted Net Debt Amount. The Review Firm shall have 45 days following such submission to review the consolidating
balance sheet 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 Parties
in respect of the Proposed Adjusted Net Working Capital Amount and the Proposed Adjusted Net Debt Amount, which shall be submitted to the Parties on the 45th day following submission to the Review Firm. In the event Owens Corning disputes the
correctness of the Proposed Adjusted Net Working Capital Amount and/or Proposed Adjusted Net Debt Amount, Owens Corning shall notify Saint-Gobain 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 Owens Corning with respect to any individual item in respect of the 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 the 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 Owens Corning’s determination of the value for such
item (provided that Saint-Gobain shall have made available sufficient information to make such determination of value), and (iii) the difference in Owens Corning’s determination of all items disputed must exceed USD 100,000 in the
aggregate. To the extent Owens Corning does not so object, in writing and in reasonable detail as required and within the time period contemplated by this Section 3.04(a), Owens Corning shall be deemed to have accepted
Saint-Gobain’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 Parties shall endeavor in good faith to resolve any disputed matters within 15 days
after the date on which the notice of objections was delivered. If the Parties 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 Party (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 Parties shall jointly engage the Unaffiliated Firm. Promptly after such engagement of the Unaffiliated Firm, the Parties will provide the Unaffiliated
Firm with a copy of this Agreement, the SG Financial Statements, the statements of Proposed Adjusted Net Working Capital Amount and/or Proposed 

  

 5 








 
Adjusted Net Debt Amount, as applicable, and any written notices of objections related thereto. Each Party 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 Party to the Unaffiliated Firm and to the other Party simultaneously within 15 days of the engagement of such Unaffiliated Firm. Each
Party shall thereafter be entitled to submit a rebuttal to the other Party’s submission, which rebuttals shall be delivered to the Unaffiliated Firm and to the other Party simultaneously within 30 days of the delivery of the Parties’
initial submissions. The Unaffiliated Firm may request additional information from either Party, but absent such a request neither Party 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 Party (i) communicate (or permit any of its Affiliates or Representatives to communicate) with the Unaffiliated Firm without providing the other
Party 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 Party. Either Party may make a written request for a hearing with the Unaffiliated Firm by delivering notice to the other Party and the Unaffiliated Firm within 15 days after the submission of rebuttals by the Parties.
Within 30 days of such written request, the Unaffiliated Firm shall hold a joint hearing, in person or by teleconference, at which each Party 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 statement of Proposed Adjusted Net Working Capital Amount and/or Proposed Adjusted Net Debt Amount
based solely on the information provided to the Unaffiliated Firm by the Parties 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 Amount 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 Amount in
dispute (it being understood that the Unaffiliated Firm will have no authority to make any adjustments to any SG Financial Statements or amounts other than the statements of Proposed Adjusted Net Working Capital Amount and/or Proposed Adjusted Net
Debt Amount 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 Party
or, in respect of items with a negative value, less than the smallest value for such item asserted by either Party. 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 Parties and judgment may be entered thereon as an arbitration award in any court of competent jurisdiction. The 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”. The Net Debt as of the close of business on the
day prior to the Closing Date (but taking into account the proceeds to be received by Saint-Gobain Vetrotex France and Saint-Gobain Vetrotex International in accordance with Exhibit B for the sale of the SG Acquired Intellectual Property
and the SG Acquired Subsidiaries listed on Schedule 3.04(a)) without giving effect to the 

  

 6 








 
reduction of any indebtedness for borrowed money resulting from the use of such proceeds and only to the extent such proceeds are not distributed to any
Saint Gobain Affiliate that is not a SG Acquired Subsidiary other than in connection with the repayment of indebtedness for borrowed money, as finally determined pursuant to this Section 3.04(a), is referred to herein as the “Adjusted
Net Debt Amount”. 
 (b) The Adjusted Net Working Capital Amount and the Adjusted Net Debt Amount shall be expressed in USD, using
the USD/EUR European Central Bank rate as of the Closing Date. 
 (c) The Proposed Adjusted Net Working Capital Amount shall be determined in
accordance with the accounting principles, policies, practices, methods and procedures used in calculating the Working Capital Threshold Amount.

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

an Asset Transferor, 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

provide to Owens Corning or its applicable Affiliate the benefits under the relevant Contract, license or permit, Saint-Gobain and Owens Corning shall cooperate following the Closing to obtain such consent or enter into an agreement with respect
thereto as soon as reasonably practicable thereafter.

 (f) Saint-Gobain and/or any of its Affiliates shall take all necessary
steps to remove, and Owens Corning and/or its Affiliates shall take the steps set forth in (g) and (h) to permit to be removed, from the Acquired Manufacturing Facilities any materials or part of materials relating to the 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 H-4 that may arise from
the manufacture, use, or sale of Business Products as manufactured, used, or sold in Saint-Gobain’s Business as conducted on or before the Closing Date.

application to be filed. 
 (o) For each patent and patent application listed on Schedule A-4 and listed on the lists attached to
Exhibits T-1 and T-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, Owens Corning shall, at least five (5) Business Days
before any such final deadline, notify Saint-Gobain of the PCT country(ies) where it reasonably wishes national stage applications based on such PCT application to be filed.

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 H-5. To avoid any doubt,
Owens Corning 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. 
  

 37 








 (s) Neither Owens Corning 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 H-6 as “R&C/TS” (i.e. as
being applicable both to the “reinforcements and composites” business and to the SG Textiles Solutions Business of Saint-Gobain). Notwithstanding the foregoing, Owens Corning or any of its Affiliates may file a patent application on
any such item of Know How that: (i) Owens Corning and Saint-Gobain agree is included in SG R&C Intellectual Property; (ii) is an improvement to, or an invention independently of, any SG R&C Intellectual Property, SG Third
Party Intellectual Property, or SG Licensed Intellectual Property, developed by Owens Corning or its Affiliates, or (iii) is Intellectual Property owned or licensed by Owens Corning or its Affiliates, from 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 H-6 shall not be construed as a presumption that every item of Know How in that category constitutes SG Licensed
Intellectual Property rather than SG R&C Intellectual Property. 
 (t) Prior to Closing, Saint-Gobain shall arrange for a joint training
program between personnel of Saint-Gobain Vetrotex International (“SGVI”) who are technically expert in the LINCC furnace modeling software of SGVI and personnel of Saint-Gobain Conception Verrière (“SGCV”)
who are technically expert in the CONVEC furnace modeling software of SGCV. Such training program shall be for the purpose of training the technical experts of each company on software of the other company sufficient to enable the technical experts
to independently use, maintain, and support the software, including its source code, and shall take place over a period of at least three (3) months. The technical experts shall identify any known difficulties in operating the current software,
and any new difficulties encountered during the training, and shall document all such difficulties. Thereafter, the technical experts from the cognizant company shall provide training and assistance to the other company’s technical experts on
ways to resolve any such documented difficulties. If any such documented difficulties remain unresolved at the conclusion of the training program, or recur thereafter, then such assistance shall continue for up to six (6) months after Closing.
The Parties acknowledge that, other than as provided in this Section 5.10(t), neither Party shall provide any technical support, maintenance, upgrades, or assistance in addressing difficulties arising from changes made after Closing, for the
LINCC or CONVEC software. 
 (u) Saint-Gobain shall ensure that, prior to Closing, SGVI and SGCV shall enter into license agreements for the
CONVEC and LINCC software, such agreements to include provision for the supply of source code for the software and to terminate and supersede existing license agreements for the software and to be in the forms set forth respectively in Exhibit
H-1 and Exhibit I-2. Saint-Gobain shall also ensure that, prior to the Closing, SGCV shall license to SGVI the Glass CAD software, such license to be on the same basis on which SGVI, on or prior to the date of this Agreement, has access
to the Glass CAD software (i.e. to executable code but not source code) and in the form set forth on Exhibit I-3 . Prior to Closing, Saint-Gobain and Owens Corning shall agree on the terms of a maintenance support agreement of the CAD
software, which shall include upgrades to the CAD software to work with newer version(s) of the Microstation software, on a fee-bearing basis for up to two years, at Owens Corning’s option. Such assistance may be renewed, provided that the
parties to the maintenance agreement agree 

  

 38 








 
on the fee and the conditions of the maintenance for the following year; it being understood that such assistance shall be granted to the licensee of the CAD
software only. 
 (v) Deloitte & Touche and Owens Corning shall mutually define and agree on a scope of work, in consultation with
Saint-Gobain, for Deloitte & Touche to prepare and provide for an independent valuation of the SG Acquired Intellectual Property for the purpose of Section 2.01. Saint-Gobain shall, and shall cause its Affiliates and Representatives
to, provide Deloite & Touche, Owens Corning and its Representatives with such reasonable assistance and cooperation as Owens Corning shall require (including access to the relevant facilities and offices, information, books, records,
documents and other papers of Saint-Gobain and Saint-Gobain’s Business where located) during normal business hours without unreasonably interfering with the operations of Saint-Gobain to assist in the preparation of such valuation. To the
extent possible, such valuation shall utilize the analysis concluded by Deloitte & Touche on November 29, 2006 and if the preliminary valuation is materially different from the November 29, 2006 valuation, Owens Corning shall
provide Saint-Gobain an opportunity to furnish further information and consult with Deloitte & Touche prior to the final determination of the valuation. Owens Corning shall coordinate and supervise Deloitte & Touche during the
valuation process in consultation with Saint-Gobain and Owens Corning shall be responsible for the cost of such valuation. 
 Section 5.11 Financial Statements. From the date of this Agreement until the Closing Date, Saint-Gobain shall provide to Owens Corning, within 45 days of the end of its fiscal quarters, the unaudited consolidating
balance sheet of Saint-Gobain’s Business as of the close of such fiscal quarter and the unaudited consolidating income statement of Saint-Gobain’s Business for such fiscal quarter. Except as set forth on Schedule 5.11, Saint-Gobain agrees
that the deliverables provided by Saint-Gobain under this Section 5.11 will be prepared in all material respects in accordance with IFRS (as applicable) and will present fairly, in all material respects, the assets, liabilities, financial
condition, the results of operations of Saint-Gobain’s Business at, and for the applicable fiscal quarter then ended (as the case may be). 
 Section 5.12 Non-compete. 
 (a) Until the third (3rd) anniversary of the Closing Date, (the “Non-Compete Period”, Saint-Gobain shall not, and shall cause its
Affiliates not to, directly or indirectly, for their own account or otherwise, in any country of the world: (i) own, operate, manage or control; (ii) serve as an officer, director, shareholder, partner, member, employee, agent, consultant,
advisor or developer or in any similar capacity; or (iii) have any financial interest in, in each of (i), (ii) or (iii), any person, business or enterprise that competes directly or indirectly with the Business; provided,
however, that Saint-Gobain or its Affiliates may (A) own and operate the business conducted by Saint-Gobain Vetrotex America, Inc. as conducted from its Wichita Falls facility, (B) own an interest of not more than five percent
(5%) of any class of security of a Person engaged in a competing business, which securities of such Person are traded on a securities exchange and (C) operate the single texturised product machine at Litomysl for supplies to Valeo.

 (b) Section 5.12(a) shall not apply to any business owned as of the date hereof by either Saint-Gobain or any of its Affiliates, that
the Parties have agreed shall not be an 

  

 39 








 
Acquired Asset (including, for the avoidance of doubt, the business conducted by Saint-Gobain Vetrotrex America, Inc. at its Wichita Falls facility
(including the sales offices, warehouses and the glass mat operations), the SG Textile Solutions Business and the single texturised product machine at Litomysl for supplies to Valeo), provided, however, that except for the business conducted at
Saint-Gobain Vetrotex America, Inc.’s Wichita Falls facility (including the sales offices, warehouses and the glass mat operations), any such business shall not manufacture or sell any Business Products except pursuant to a written supply,
license, and/or tolling agreement with Owens Corning or its Affiliates. 
 (c) Section 5.12(a) shall not prohibit the acquisition,
directly or indirectly, by Saint-Gobain or any of its Affiliates, of any business assets or shares which cause it to be in breach of Section 5.12(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 USD20 million, in each case calculated based on the relevant annual financial statements for the most recent complete financial year.

 (d) If Saint-Gobain or any of its Affiliates becomes the owner of any Prohibited Asset at any time during a Non-Compete Period,
Saint-Gobain 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, Saint-Gobain 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 offer in favor of Owens Corning or an Affiliate thereof designated by Owens Corning, which right of first offer shall be exercised in accordance with Section 5.12(e). 
 (e) Promptly but no later than twenty (20) Business Days following the acquisition of the Prohibited Asset by Saint-Gobain or any of its Affiliates,
Saint-Gobain shall give written notice (a “ROFO Transferor’s Notice”) to Owens Corning 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 Owens Corning is referred to hereinafter as the “ROFO Notice Date.” Owens Corning shall have sixty (60) days following the ROFO Notice Date to notify Saint-Gobain in writing whether
Owens Corning wishes to buy such Prohibited Asset on the same terms as set forth in the ROFO Transferor’s Notice (the “ROFO Notice”). If Owens Corning either fails to give the ROFO Notice within such sixty
(60) day period or notifies Saint-Gobain that it does not wish to purchase the Prohibited Asset, Owens Corning shall be deemed to have declined to purchase such Prohibited Asset and Saint-Gobain 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 

  

 40 








 
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
Saint-Gobain 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 5.12(e). If Owens Corning does provide a ROFO Notice to Saint-Gobain within such sixty (60) day period, such ROFO Notice shall be deemed to create a binding agreement between
Saint-Gobain or its applicable Affiliate and Owens Corning (or the Affiliate designated by Owens Corning 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. Saint-Gobain 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 Owens Corning or its designated Affiliate shall take place at a time and place reasonably acceptable to Saint-Gobain or its applicable Affiliate and Owens Corning or its designated Affiliate; 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 Saint-Gobain of the ROFO Notice.
Each of Saint-Gobain or its applicable Affiliate, on the one hand, and Owens-Corning or its designated Affiliate, on the other hand, shall pay its own costs and expenses in connection with the transaction. 
 Section 5.13 Confidentiality. For a period commencing on the Closing Date and ending on the ten year anniversary thereof, Saint-Gobain shall,
and shall cause its Affiliates to, treat and hold as confidential, any and all technical, economic, financial, or marketing information or other proprietary or confidential information concerning the Business. In the event Saint-Gobain or any of its
Affiliates 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 Saint-Gobain shall notify Owens Corning promptly of the request or requirement so that Owens Corning, at its own expense, may seek an appropriate protective order or waive compliance with this
Section 5.13. If, in the absence of a protective order or receipt of a waiver hereunder, Saint-Gobain is, on the advice of counsel, compelled to disclose such confidential information, Saint-Gobain may so disclose the confidential or
proprietary information; provided that Saint-Gobain shall use reasonable efforts to obtain reliable assurance that confidential treatment shall be accorded to such confidential or proprietary information. The provisions of this
Section 5.13 shall not be deemed to prohibit the disclosure by Saint-Gobain of confidential or proprietary information relating to the operations or affairs of the Business 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 Owens Corning 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 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 Saint-Gobain shall use reasonable efforts to obtain


  

 41 








 
reliable assurance that confidential treatment shall be accorded to such confidential or proprietary information. Notwithstanding the foregoing, the
provisions of this Section 5.13 shall not apply to information that (x) is or becomes publicly available other than as a result of a disclosure by Saint-Gobain, (y) is or becomes available to Saint-Gobain on a non-confidential basis
from a source that, to the knowledge of Saint-Gobain, is not prohibited from disclosing such information by a legal, contractual or fiduciary obligation, or (z) is or has been independently developed by Saint-Gobain other than through the use
of information available to Saint-Gobain prior to the Closing.

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 Party (to the extent reasonably
practicable) and without complying with Applicable Law. Notwithstanding the foregoing, no 

  

 42 








 
provision of this Agreement shall (a) relieve either Party from any of its obligations under the Non-Disclosure Agreement or (b) terminate any of

otherwise transfer or dispose of the Businesses and assets set forth on Schedule 6.04(b)(1). For the avoidance of doubt, and notwithstanding any provision in this Agreement, it is understood that Owens Corning shall be required to take all

Authority, to retain, sell or otherwise transfer or dispose of the Businesses and assets set forth on Schedule 6.04(b)(2). Except as provided in the immediately preceding sentence, in no event shall Saint-Gobain be required to offer as a
remedy, or to agree with any competent Governmental Authority, to sell or otherwise transfer or dispose of any assets or businesses of Saint-Gobain or its Affiliates. The Parties 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 

  

 43 








 
shall be obligated to provide the Party initiating the contest with all reasonable assistance in the conduct of such contest. 
 (c) The Parties 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

the subject of this Agreement, permit the other Party to review in advance any communications proposed to be made by such other Party 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 Party 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 Party in advance and, to the extent permitted by such Governmental Authority, gives the other Party 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 Party shall (i) provide the other with such assistance as may be reasonably requested in connection with the preparation of any Tax Return
relating to an SG Acquired Subsidiary or the SG Acquired Assets 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 upon reasonable request provide to the other all records and other information that may be relevant to any such
Tax Return, audit or examination, proceeding or determination, and (iii) provide the other 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

(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 SG Acquired Assets, the SG Acquired Subsidiaries or the SG Assumed Liabilities. 
 (b) The Parties 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 Parties will provide to each other upon request all information necessary to permit Owens Corning to apply the provisions of Section 41(f)(3)(A) of the Code. 
  

 44 








 (c) Owens Corning shall timely prepare all Tax Returns with respect to the SG Acquired
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 Saint-Gobain (which consent shall not be unreasonably withheld or delayed), shall file or cause to be filed such Tax Returns. Saint-Gobain acknowledges and agrees that Tax
Returns prepared by Owens Corning pursuant to this Section 6.05(c) may include, at the discretion of Owens Corning, United States federal (and applicable state and local) Tax Returns of non-U.S. SG Acquired 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
Acquired Subsidiaries to change their reporting period for any purposes other than United States tax purposes (including financial accounting and non-US tax purposes), (ii) Owens Corning 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 Acquired Subsidiaries or of Saint-Gobain or of any of their Affiliates.

 (d) Owens Corning shall pay or cause to be paid all Taxes with respect to the SG Acquired Assets and the SG Acquired
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 Saint-Gobain shall be liable for and shall reimburse Owens Corning 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 and attributable to the
SG Acquired Subsidiaries (except to the extent that such Taxes were taking into account as a liability in calculating the Adjusted Net Working Capital, the Adjusted Net Debt, or as provided in Section 6.05(k))). Any Taxes arising from or
with respect to the SG Acquired Subsidiaries or the Business for a Straddle Period shall be apportioned between the Parties by allocating real and personal property taxes and any other ad valorem taxes between Parties 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 SG Acquired 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. Owens Corning shall reimburse Saint-Gobain for any such Taxes paid by Saint-Gobain for which
Owens Corning is liable pursuant to this Section 6.05(d). 
 (e) Saint-Gobain shall be liable for, and shall hold harmless and
indemnify Owens Corning and its Subsidiaries (including the SG Acquired Subsidiaries) against, Taxes (and related Damages) imposed on Owens Corning any of its Subsidiaries or the SG Acquired Assets that are attributable 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 Adjusted Net Working Capital and Adjusted Net Debt and taking into
account any resulting actual refund or reduction in liability for Taxes imposed on Owens Corning 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, and except as provided in Section 6.05(k) and excluding Taxes (or increased amount of Taxes) which would not have arisen but for any change of methods of tax accounting, elections or other calculation 

  

 45 








 
principles effected after the Closing Date and effective for Tax period or portions thereof ending on or before the Closing Date (other than any such changes
that are required by law)). For the avoidance of doubt, Saint-Gobain’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 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 Owens Corning or the SG Acquired 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 Owens Corning or the SG Acquired Subsidiaries, then Owens Corning shall within 10 days of receipt provide written notice of such Tax Claim to the party hereunder that would be required to indemnify
Owens Corning 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 Owens Corning. 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) Owens Corning shall control the defense and prosecution of all Tax Claims. The Tax Indemnifying Party shall
cooperate in good faith with Owens Corning and its authorized representatives in order to contest effectively such Tax Claim. Owens Corning 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. Owens Corning shall provide the Tax Indemnifying Party drafts of all written submissions relating to such Tax Claims in advance for comment
and review. 
 (iii) Owens Corning 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, Owens Corning 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 Owens Corning and the Tax Indemnifying Party. 
 (g) Owens Corning may at its own discretion make one or more
elections under Section 338(g) of the Code with respect to the direct or indirect acquisition of any non-U.S. SG Acquired Subsidiaries. 
  

 46 








 (h) Any refund of Income Taxes of any SG Acquired Subsidiary or the SG Acquired Assets for any period or
portion thereof ending on or before the Closing Date, to the extent not included in the calculation of the Saint-Gobain Adjusted Net Working Capital Amount and not reflecting a Tax for which Owens Corning is indemnifying Saint-Gobain pursuant to
Section 6.05(k), shall be for the account of Saint-Gobain. Owens Corning shall, or shall cause its Affiliates to, forward to Saint-Gobain any such refund within 10 days after such refund is received or applied against other Income Tax
liability. Except as otherwise required by applicable law, the parties shall treat any payments under the preceding sentence as an adjustment to the price paid for the relevant SG Acquired Subsidiary or SG Acquired Asset. Owens Corning shall
promptly notify Saint-Gobain of any entitlement to any such refund or credit referred to above, and shall, if Saint-Gobain so requests and at Saint-Gobain’s expense, cause the relevant SG Acquired Subsidiary to file for and obtain any refund
determined by Saint-Gobain to be due to Saint-Gobain. Owens Corning shall permit Saint-Gobain to control at Saint-Gobain’s expense the prosecution of any such refund claimed, following procedures consistent with those provided for Tax Claims in
Section 6.05(f). 
 (i) Owens Corning and Saint-Gobain agree to report all transactions regarding the SG Acquired Subsidiaries not in
the ordinary course of business occurring on the Closing Date after Owens Corning’s acquisition of the SG Acquired Subsidiaries on Owens Corning’s or a Subsidiary’s federal income Tax return to the extent permitted by United States
Treasury regulation Section 1.1502-76(b)(1)(ii)(B). 
 (j) The Parties agree, to the extent permitted by law, to treat all
indemnification payments made pursuant to this Agreement as adjustments to the Purchase Price for United States federal income and other applicable Tax purposes. 
 (k) Notwithstanding the proviso to Section 6.05 (d) or Section 6.05 (e), Saint-Gobain and its Affiliates shall not be liable for, and Owens Corning shall hold harmless and indemnify Saint-Gobain
and its Affiliates on an after-Tax basis against, any Taxes and related Damages imposed on Vetrotex France SA or Vetrotex International SA that are attributable to the sale pursuant to Section 2.01 of this Agreement of (i) SG R&C
Intellectual Property by Vetrotex France SA to a Purchasing Company and (ii) SG Acquired Subsidiaries by Vetrotex France SA and Vetrotex International SA as Subsidiary Transferors. In addition, Owens Corning shall hold harmless and indemnify
Saint-Gobain and its Affiliates, on an after-Tax basis, against any Incremental Taxes and related Damages; provided, in order to avoid double recovery, that Owens Corning’s indemnification obligation under this sentence shall exclude any
Taxes and related Damages indemnified by Owens Corning pursuant to the first sentence of this Section 6.05 (k). For the avoidance of doubt, Owens Corning’s indemnification obligations under this Section 6.05 (k) shall
include any Taxes or Incremental Taxes (and related Damages) arising as a result of a later audit or examination or required by law and shall not be subject to (nor taken into account for the calculation of) the Indemnity Caps or the Indemnity
Threshold. 
 (l) Notwithstanding any other provision of this Agreement, if there shall be any dispute, controversy or claim (a “Tax
Dispute”) between the Parties arising out of, relating to, or connected with this Section 6.05, the Parties shall use their best efforts to resolve the matter on an amicable basis and in a manner fair and equitable to the Parties. If
one Party notifies another Party that a Tax Dispute has arisen and the Parties are unable to resolve the Tax 

  

 47 








 
Dispute within thirty (30) days from such notice, then the matter shall be referred to Deloitte & Touche for resolution. Thereafter, such Tax
Dispute shall be resolved by Deloitte & Touche following procedures consistent with those set forth in Section 3.04(a). 
 Section 6.06 Administration of Accounts. All payments and reimbursements received by Saint-Gobain or its respective Affiliates after the Closing Date that would have been payable to an SG Acquired Subsidiary prior to the Closing
Date shall be promptly paid over to Owens Corning without right of set-off. All payments and reimbursements that constitute SG Excluded Assets or relate to an SG Excluded Liability received by Owens Corning or its respective Affiliates
after the Closing Date shall be promptly paid over to Saint-Gobain without right of set-off. 
 Section 6.07 Undisclosed
Contracts. Promptly after the date hereof, subject to Applicable Law, 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) Owens Corning
and its Representatives to conduct a review of the Undisclosed Contracts of Saint-Gobain’s Business to which Owens Corning shall have been denied access prior to the date hereof, and (ii) Owens Corning 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), Saint-Gobain shall permit Owens Corning’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. Owens Corning, nor any SG Acquired 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, Saint-Gobain 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 or in Schedule 6.09, Saint-Gobain shall
cause all agreements between an SG Acquired Subsidiary and any Affiliate thereof (other than another SG Acquired Subsidiary) to be terminated prior to the Closing.

 Section 6.11 Termination of Positions. Until
the first anniversary of the Closing Date, Owens Corning shall not (a) terminate the employment of the persons set forth in Schedule 6.11 (other than for cause) or (b) adversely change in any material respect the position, title,
reporting responsibilities, compensation, benefits and other terms and conditions of employment of the 

  

 48 








 
persons set forth on Schedule 6.11 offered to such persons on the Closing Date without the prior written agreement of Saint-Gobain. 
 Section 6.12 Financial Statements Cooperation. Saint-Gobain shall, and shall cause its Affiliates and Representatives to and shall direct its
auditors to, provide Owens Corning and its Representatives with such reasonable assistance and cooperation as Owens Corning shall require (including access to the relevant information, books, records, documents and other papers of Saint-Gobain and
Saint-Gobain’s Business where located ) during normal business hours without unreasonably interfering with the operations of Saint-Gobain to assist in the preparation of such financial statements concerning Saint-Gobain’s Business as may
be required to be included in any filing by Owens Corning under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended. 
 Section 6.13 Indebtedness and Cash Maintenance. 
 (a) Subject to Section 3.04, prior to, or
simultaneously with, Closing, Saint-Gobain shall cause all outstanding indebtedness for borrowed money (including any prepayment, change of control or other similar penalties and related costs and expenses) of all SG Acquired Subsidiaries (other
than indebtedness for borrowed money of one SG Acquired Subsidiary to another SG Acquired Subsidiary) to be paid off such that all obligations related to such indebtedness shall be fully discharged. Notwithstanding the foregoing, Saint-Gobain shall
not be obligated to discharge indebtedness for borrowed money: 
  

	 	(i)	in respect of the SG Acquired Subsidiaries listed on Schedule 6.13(a) (the “Specified Subsidiaries”), up to an aggregate of EUR15,000,000 of outstanding
indebtedness for borrowed money (“Developing Country Debt”) using applicable exchange rates as of 5:00 p.m. Central European time on the Business day prior to the Closing in accordance with the procedures used in calculating
the SG Reference Date Balance Sheet; and 

  

	 	(ii)	in respect of SG Acquired Subsidiaries which are not Specified Subsidiaries, up to an aggregate amount equal to the net cash position (cash or cash equivalents minus
outstanding indebtedness for borrowed money as of the Closing) of the Specified Subsidiaries (“Developed Country Debt”), subject to the limitations on cash and cash equivalents set forth in Section 6.13(b).


 (b) Subject to Section 3.04, prior to Closing, Saint-Gobain shall take, and shall cause its Affiliates to take, all
necessary action to ensure that immediately prior to Closing, the Specified Subsidiaries shall not have cash in excess EUR40,000,000 in the aggregate using applicable exchange rates as of 5:00 p.m. Central European time on the Business day
prior to the Closing in accordance with the procedures used in calculating the SG Reference Date Balance Sheet. For purposes of this Agreement, any amount of cash held by the Specified Subsidiaries in excess of EUR 40,000,000 in the aggregate,
shall be referred to herein as “Excess Cash”. 
 (c) Except as set forth in Schedule 6.13(c) and subject to
Section 3.04, Owens Corning shall cause all Developed Country Debt to be paid off on the Closing Date. 

  

 49 








 
Except (i) as set forth in Schedule 6.13(c) and (ii) as the borrower may be prohibited by Applicable Law and subject to
Section 3.04, Owens Corning shall cause to be paid off at Closing all Developing Country Debt (other than Developing Country Debt that is owed to third parties not Affiliates of Saint-Gobain except as provided herein); provided that
Saint-Gobain shall have first delivered to Owens Corning no later than September 15, 2007, a list of all such Developing Country Debt setting forth the maximum amounts thereof for each Specified Subsidiary to be paid off at Closing (the
“Developing Country Debt List”), failing which Owens Corning shall not be obligated to pay off such Developing Country Debt at Closing. Owens Corning and Saint-Gobain shall promptly following the date hereof together
advise all third-party lenders of Developing Country Debt who are not Affiliates of Saint-Gobain of the transactions contemplated hereby, including the change of control of any of such lender’s borrower. Should any such lender request that its
Developing Country Debt be repaid at or prior to the Closing, Saint-Gobain may at its option repay such Developing Country Debt at or prior to the Closing. To the extent that the existing terms of any such Developing Country Debt shall entitle the
lender to require the borrower to repay such loan upon a change of control event and such lender so requires, Owens Corning shall cause such Developing Country Debt to be paid off at Closing subject to Section 3.04. Any tax liability
associated with the payment of any indebtedness (including the payment of any accrued interest thereon) pursuant to this Section 6.13(c) will be paid by the lender of such indebtedness. Saint-Gobain shall provide Owens Corning no later
than seven days prior to the Closing Date a written statement of the amount of Developed Country Debt and no later than fifteen days prior to the Closing Date a written statement of Developing County Debt to be repaid at Closing by the relevant SG
Acquired Subsidiaries. 
 Section 6.14 Refractory Metal. From the date hereof until the Closing Date, Saint-Gobain shall not, and
shall cause its Affiliates not to, sell or remove any Metal containing refractory materials used in SG’s Business or Metal recovered from refractory materials used in SG’s Business.

 INTENTIONALLY OMITTED 
 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, Owens Corning shall, or cause 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 Owens Corning or its Subsidiaries or accept such offers of
employment with Owens Corning or its Subsidiaries will be referred to as the “Transferred Employees”). Owens Corning also shall, or shall cause its 

  

 50 








 
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 Saint-Gobain or its Affiliates would have been required immediately prior to the Closing Date to reinstate such Inactive Employee pursuant to Applicable Law
or any applicable Saint-Gobain policy (pursuant to the terms of such policy as in effect as of the date hereof). A list of Inactive Employees as of July 10, 2007 is set forth on Schedule 8.01(a). Such list shall be updated by
Saint-Gobain as of the Closing Date. Any Inactive Employee who returns to active employment or becomes actively employed by Owens Corning 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 Transferred Employee upon his or her return to active employment with Owens Corning or its Subsidiaries. Business Employees who do not become actively employed by Owens Corning or its Subsidiaries
shall not be considered Transferred Employees under this Agreement, and Owens Corning and 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
Saint-Gobain or its Affiliates. 
 (b) Terms and Conditions of Employment. For all hourly and salaried Transferred Employees who are
not covered by a collective bargaining agreement that covers the terms and conditions of employment and that will be assumed by Owens Corning or its Subsidiaries as of the Closing Date, except where Applicable Law provides otherwise,
Owens Corning 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 Saint-Gobain and/or its Affiliates immediately prior to the Closing Date; provided, however, the base salary,
work location, and any other applicable benefits to be offered to Transferred Employees shall be such that the transfer of employment to Owens Corning or any of its Subsidiaries should not result in the entitlement to severance benefits under
any plan of Saint-Gobain or its Affiliates or Applicable Law. Subject to the requirement in the preceding sentence regarding the avoidance of triggering severance payments, Owens Corning shall have the sole discretion to determine the wages,
employee benefits and terms of employment to be provided to Transferred Employees; provided, however, the intended employee benefits to be initially provided to the Transferred Employees shall include those provided through: the Transferred DB
Plans, Transferred DC Plans, existing Owens Corning benefit 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. In the event that Owens Corning offers to enter into an individual arrangement with a Transferred
Employee, then the Transferred Employee may choose to enter into such arrangement in lieu of receiving the compensation and benefits specified above. 
  

 51 








 (c) Employees Representative Agreements. As of the Closing Date, Owens Corning 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 Transferred
Employees to the extent required by Applicable Law and to the same extent Saint-Gobain and its Affiliates were required to do so, or (ii) except as otherwise determined by Owens Corning, 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 Transferred Employees, and to recognize and bargain in good faith with any union that
has been certified or recognized as the collective bargaining representative of Transferred Employees who are employed by Owens Corning and/or its Subsidiaries. Saint-Gobain and its Affiliates and Owens Corning 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.
Owens Corning shall, or shall cause its Subsidiaries to, credit Transferred Employees for service earned prior to the Closing Date with Saint-Gobain and its Affiliates, or any of its predecessor members of the Saint-Gobain group of companies,
(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 Owens Corning or any of its Subsidiaries for the benefit of the Transferred 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 Saint-Gobain and its
Affiliates immediately prior to Closing Date, and (B) Transferred 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.

 (e) Pre-existing Conditions; Coordination. Where applicable, Owens Corning shall, or shall cause its Subsidiaries to, waive
limitations on benefits relating to any pre-existing conditions of the Transferred Employees and their eligible dependents to the extent that such limitations were waived under the applicable SG Benefit Plan. Where applicable, Owens Corning
shall, and shall cause its Subsidiaries to, recognize for purposes of annual deductible and out-of-pocket limits under their health plans applicable to Transferred Employees, deductible and out-of-pocket expenses paid by Transferred Employees and
their respective dependents under Saint-Gobain’s or any of its Affiliates’ health plans in the calendar year in which the Closing Date occurs to the extent that Saint-Gobain provides Owens-Corning as of the Closing Date with detailed
information as to the amount of such deductible and out-of-pocket expenses paid by the Transferred Employees. 
 Section 8.02
Allocation of Pre-Closing Employment Liability. Saint-Gobain or its Affiliates 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 

  

 52 








 
liabilities (including but not limited to wages, bonuses, commissions, vacation, leave, employee benefits, severance, and other compensation), for
Transferred 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. Owens Corning or its Subsidiaries shall be responsible for any and all employment-related obligations and liabilities for Transferred 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 Owens Corning 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 Owens Corning 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 pension benefit plan that was sponsored by Owens Corning or its Affiliates immediately prior to Closing that is set forth in Schedule
8.04(a)(ii)(A) (the “OC DB Plans”), the Owens Corning Actuary and the Saint-Gobain Actuary (together with the Owens Corning Actuary, the “Actuaries”) shall determine within 60 days of the Closing Date the value
of the projected benefit obligation (based on census data as of the Closing) of such OC DB Plan based on a FAS/IAS methodology and on the actuarial assumptions set forth on the applicable Benefit Schedule using discount rates based on applicable
local bond yields at Closing in accordance with applicable FAS/IAS methodology, the market value of the assets of each such OC DB Plan as of the Closing Date and using applicable exchange rates as of the Closing Date in accordance with the
procedures used by Owens Corning in applying exchange rates in its financial statements (excluding from such calculation any contributions made following the date hereof by Owens Corning or its Affiliates in excess of the minimum funding
requirements under Applicable Law, except with respect to contributions made to the funded OC DB Plan in Japan up to the amount of the OC Pre-Close Unfunded Liabilities and Ongoing Service Cost with respect to such plan). 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 (based on census data as of the Closing) of such SG Transferred DB Plan based on a FAS/IAS methodology and on the actuarial assumptions set forth on the applicable Benefit Schedule using discount rates based on applicable local bond
yields at Closing in accordance with applicable FAS/IAS methodology, the market value of the assets of each such Transferred DB Plan as of the Closing Date and using applicable exchange rates as of the Closing Date in accordance with 

  

 53 








 
the procedures used in calculating the SG Reference Date Balance Sheet. The excess of the value of the projected benefit obligation of an OC DB Plan over the
current assets of such OC DB Plan as of the Closing Date constitutes the “OC Unfunded Liabilities” of such OC DB Plan. Within 60 days after the Closing Date, the Actuaries shall determine the aggregate OC Unfunded Liabilities for
all the OC DB Plans (the “OC Pre-Close Unfunded Liabilities”). The excess of the value of the projected benefit obligation of an SG Transferred DB Plan over the current value of the assets of such SG Transferred DB Plan as of the
Closing Date constitutes the “SG Unfunded Liabilities” of such SG Transferred DB Plan. Within 60 days after the Closing Date, the Actuaries shall determine the aggregate SG Unfunded Liabilities for all the SG Transferred DB Plans
(the “SG Pre-Close Unfunded Liabilities”). 
 (B) The Parties 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. 
 (iii) 
 (A) In the event that (I) the amount by which the SG Pre-Close Unfunded Liabilities (as finalized in accordance with this Section 8.04) exceed
two-thirds of the OC Pre-Close Unfunded Liabilities (as finalized in accordance with this Section 8.04) exceeds (II) the SG Unfunded Base Amount, Saint-Gobain shall pay to Owens Corning, in USD, on the fifth Business Day after the calculation
of such amounts are finalized in accordance with this Section 8.04, an amount equal to such excess amount, with interest from the Closing Date until payment in full at a rate equal to LIBOR plus 30 basis points in immediately available funds by
wire transfer to a bank account designated in writing by Owens Corning. 
 (B) In the event that (I) the amount by which the SG
Pre-Close Unfunded Liabilities (as finalized in accordance with this Section 8.04) exceed two-thirds of the OC Pre-Close Unfunded Liabilities (as finalized in accordance with this Section 8.04) is less than (II) the SG Unfunded Base
Amount, Owens Corning shall pay to Saint-Gobain, in USD, on the fifth Business Day after the calculation of such amounts are finalized in accordance with this Section 8.04, an amount equal to such difference, with interest from the Closing Date
until payment in full at a rate equal to LIBOR plus 30 basis points in immediately available funds by wire transfer to a bank account designated in writing by Saint-Gobain. 
  

 54 








 (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 Owens Corning 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 any applicable consents, consultations and approvals required by Applicable Law to transfer or caused to be transferred to Owens Corning 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, Transferred 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 Transferred 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 SG Benefit Plans Other than Transferred Plans. The Parties agree that the sponsorship, obligations, and liabilities (including
any withdrawal liability/debt on employer in respect of the Retained DB Plan in the UK, even if assessed after the Closing Date, but in respect of the period ending on or prior to the Closing Date, and any liability of any member of the Owens
Corning group in respect of the Retained DB Plan in the UK as a result of a contribution notice or a financial support direction issued by the pension regulator under the Pension Act 2004) in respect of SG Benefit Plans other than the Transferred DB
Plans and Transferred DC Plans will be retained, reimbursed or assumed solely by Saint-Gobain or any of its Affiliates. Saint-Gobain shall take all appropriate and necessary actions to effectuate the foregoing. 
 Section 8.05 Allocation of Risk Benefit Liabilities. The Parties agree that with respect to a Transferred Employee 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 Saint-Gobain or any of its Affiliates 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, Owens Corning and any of its Subsidiaries shall be responsible for such liability or cost. Moreover, Owens Corning 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, 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 

  

 55 








 
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. 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, Owens Corning 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
Transferred Employees on or after the Closing Date. 
 Section 8.07 Cooperation and Assistance. 
 (a) Cooperation of the Parties. On and after the Closing Date, Saint-Gobain shall, and shall cause their Affiliates to, cooperate with
Owens Corning and its Subsidiaries to provide, to the extent permitted by Applicable Laws, such current information regarding the Transferred Employees, Inactive Employees and former SG Employees on an ongoing basis as may be reasonably
necessary to facilitate determinations of eligibility for, and payments of benefits to, the Transferred Employees under the employee benefit plans of Owens Corning and its Subsidiaries. 
 (b) Consultation with Employee Representative Bodies. The Parties hereto shall, and shall cause their respective Affiliates to, mutually cooperate
in undertaking all 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. Saint-Gobain shall, and shall cause its
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 Owens Corning 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
Owens Corning or its Subsidiaries, Saint-Gobain or its Affiliates shall secure such consent or obtain a waiver of the requirement for such consent. Saint-Gobain shall, and shall cause its respective Affiliates to ensure that no secondment
agreement or arrangement transferred to Owens Corning or its Subsidiaries shall be terminated or cancelled by Saint-Gobain or its Affiliates, unless otherwise expressly agreed to in writing by Owens Corning or its Subsidiaries. 

Section 8.09 Layoffs. From the date of this Agreement until the Closing Date, Saint-Gobain shall not, and shall cause their respective
Affiliates not to, take any action affecting 

  

 56 








 
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. 
 Section 8.10 Key Employees. 
 (a) [Intentionally Omitted.] 
 (b) Prior to or on the Closing Date, Saint-Gobain shall, and shall cause its Affiliates to, cause (or, where employee consent is required under
Applicable Law, use its best efforts to cause) each of its employees who are essential to the effective operation of the Business to be transferred to or become employed by Owens Corning or its Subsidiaries unless otherwise expressly agreed to
in writing by both Parties. Each essential SG employee shall be referred to as a “Key SG Employee” and shall be listed in Schedule 8.10(b) under the subheading “Key SG Employees”. 
 (c) Schedule 8.10(c) contains a list of those Key SG Employees, if any, for which the Parties as of the date of this Agreement have expressly
agreed will not be transferred to Owens Corning or its Subsidiaries. Schedules 8.10(b) and 8.10(c) shall be updated as of the Closing Date, subject to the express written agreement by the Parties. 
 Section 8.11 No Third-Party Beneficiaries. The provisions of this Article VIII are solely for the purposes of the respective Parties to
this Agreement and nothing in this Agreement expressed or implied shall confer upon any current or former Transferred Employee or SG Employee or upon any representative of any such person, or upon any collective bargaining agent, any rights or
remedies, including any third party beneficiary rights or any right to employment or continued employment for any specified period, of any nature or kind whatsoever under or by reason of this Agreement.

have completed its the reorganizations described on Exhibit C as contemplated by Section 2.03. 
 Section 10.03
Conditions to Obligations of Saint-Gobain. The individual obligations of Saint-Gobain to consummate the Closing are subject to the satisfaction (or waiver by Saint-Gobain) of the following further conditions: 
 (a) (i) Owens Corning shall have performed in all material respects all of its obligations under this Agreement required to be performed by it at or
prior to the Closing, (ii) the representations and warranties of Owens Corning contained in this Agreement shall be true and correct at and as of the date of this Agreement and as of the Closing Date, as if made at and as of each such date,
except that those representations and warranties that by their express terms are made as of a specific date shall be required to be true and correct only as of such date, and (iii) Saint-Gobain shall have received a certificate signed by an
officer of Owens Corning to the foregoing effect; and 
 (b) Owens Corning (or its applicable Affiliates) shall have executed and delivered,
on or before the Closing Date, each of the Transaction Documents that are required to be executed by Owens Corning or its Subsidiaries.; and 
 (c) Owens Corning shall have provided Saint-Gobain with evidence, to Saint-Gobain’s reasonable satisfaction of the discharge of Developed Country Debt and Developing Country Debt owed to third parties other than Saint-Gobain and
its Affiliates in accordance with Section 6.13(c); 
 Section 10.04 Updated Disclosure Schedules. At any time prior to the
Closing, each Party shall be required to deliver to the other Party notice (a “Disclosure Notice”) of any event or circumstance that (i) was required to be disclosed on the Disclosure Schedules as of the date of this Agreement,
but which such Party failed to so disclose and/or (ii) occurs after the date of this Agreement but on or before the Closing Date that would have been required to be disclosed on the Disclosure Schedules on the date of this Agreement had such
event or circumstance existed on the date of this Agreement. Disclosure Notices shall be delivered promptly following the date on which the Party obtains knowledge of the existence of an applicable event or circumstance, must be clearly marked as
such and must be addressed to Owens Corning at the addresses listed in Section 13.01. In the event any Party delivers a Disclosure Notice within three days of any date scheduled for Closing, the other Party shall be entitled to extend, by
written notice to the updating Party, the scheduled date for Closing to the third day after it receives the Disclosure 

  

 59 








 
Notice, or if such day is not a Business Day, to the next Business Day. Except for those representations, warranties, covenants or other agreements that
provide for the ability of a Party to update its respective Disclosure Schedules for specified purposes, a Disclosure Notice delivered by a Party shall be deemed to have been delivered solely for informational purposes and shall not be deemed to
update the Disclosure Schedules or cure any breach of any representation, warranty, covenant or other agreement for any purposes under this Agreement (including for purposes of Sections 10.02 and 10.03 and Article XI) or to prejudice any rights
of the other Party under this Agreement, including the right to claim that the representations and warranties of the updating Party, when made on the date of this Agreement or as of the Closing Date, were untrue, or that any condition to Closing was
unfulfilled. Notwithstanding anything to the contrary contained herein, and without any further action by the Parties, the Disclosure Schedules shall be deemed to have been updated as of the Closing Date to reflect changes in the identity of the
parties referenced therein resulting from the Reorganizations. 
 ARTICLE XI

 Section 11.01 Survival. None of the
representations, warranties, covenants or agreements of the Parties contained in this Agreement shall survive the Closing, except that: 
 (a)
solely for purposes of the indemnification provided in Sections 11.02(a)(1) and 11.02(b)(1) and 11.02(c)(i): 
 (i) the representations and
warranties in Sections 4.01(a) and (b) and Sections 4.02(a) and (b) shall survive the Closing indefinitely;

warranties in Section 4.02(q) shall survive the Closing for a period ending upon the later of three years from the Closing Date or 60 days following the date on which the applicable statute of limitations expires; 
 (iii) the representations and warranties in Section 4.02(n) shall survive the Closing for a period of seven years from the Closing Date; and 

(iv) the representations and warranties in Sections 4.01 and 4.02 (other than those Sections referenced in the preceding clauses (i), (ii) and (iii),
which shall survive solely to the extent provided by such clauses (i), (ii) and (iii)) shall survive the Closing for a period of two years from the Closing Date; 
 (b) those covenants and agreements set forth in this Agreement that, by their terms, are to have effect after the Closing Date shall survive for the period contemplated by the covenants and agreements, or if no period

 60 








 The representations, warranties, covenants and agreements referenced in the preceding clauses (a), (b) and
(c) as surviving the Closing are referred to herein as the “Surviving Representations or Covenants”. It is understood and agreed that (x) after the Closing, the sole and exclusive remedy with respect to any breach of any
Surviving Representation or Covenant shall be a claim for Damages (whether by contract, in tort or otherwise, and whether in law, in equity or both) made pursuant to this Article XI; provided, that notwithstanding the foregoing, nothing in
this Article XI shall limit the right of any Party (A) to pursue an action for or to seek remedies with respect to claims for fraud or (B) to seek specific performance or other equitable relief; and (y) before the Closing, the Parties
shall be entitled to the termination and other remedies set forth in Article XII and indemnification under this Article XI shall not apply. 
 Section 11.02 Indemnification. 
 (a) Effective as of the Closing and subject to the limitations
set forth in Section 11.04(a), Owens Corning hereby indemnifies each of Saint-Gobain, its Affiliates and its Representatives (together with their respective successors and permitted assigns) (the “SG Indemnified
Parties”) against, and agrees to defend and hold them harmless from, any and all Damages incurred or suffered by any of them arising out of, resulting from or related to any breach of any Surviving Representation or Covenant made or to be
performed by Owens Corning or its Subsidiaries pursuant to this Agreement. 
 (b) Effective as of the Closing and subject to the
limitations set forth in Section 11.04(b), Saint-Gobain hereby indemnifies each of Owens Corning, its Affiliates and its Representatives (together with their respective successors and permitted assigns) (the “OC Indemnified
Parties”) against, and agrees to defend and hold them harmless from, any and all Damages incurred or suffered by any of them arising out of, resulting from or related to (1) any breach of any Surviving Representation or Covenant made
or to be performed by Saint-Gobain or its Affiliates pursuant to this Agreement, (2) any SG Excluded Liabilities (including Saint-Gobain’s or any of its Subsidiaries’ failure to perform or in due course pay or discharge any
Saint-Gobain Excluded Liability), or (3) any matters for which indemnification is provided by Saint-Gobain under Article VIII (it being understood that the terms of such indemnification shall be governed by and subject to the terms of
Article VIII to the extent such terms differ from the provisions of this Article XI), (4) any SG Indemnified Environmental Matters, (5) any SG Indemnified Excluded Environmental Matters, or (6) any breach of the covenant set forth in
Section 5.10 (k) and (7) any willful act of fraud, misfeasance or malfeasance taken prior to Closing by an employee or agent of Saint-Gobain or any of its Subsidiaries. 
 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 

  

 61 








 
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 

  

 62 








 
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. 
 Section 11.04 Limitations. Notwithstanding anything to the contrary in this Agreement or in any of the Transaction Documents (with the
exception of the obligations of Owens Corning set forth in Section 6.05(k) which shall not be subject in any respect to the provisions set forth in this Section 11.04): 
 (a) Owens Corning shall have no liability to the SG Indemnified Parties in respect of indemnification claims pursuant to breaches of representations or
warranties (as distinguished from breaches of covenants and agreements) under Section 11.02(a)(1) unless and until: 
 (i) such Damages
are Recoverable Damages; and 
 (ii) such Recoverable Damages in the aggregate exceed USD 5,000,000 (the “Indemnity
Threshold”); provided, that if the Indemnity Threshold is reached, the entire amount of all such Damages shall be subject to indemnification under this Section 11.04(a) up to a total of USD600,000,000 (the “OC Indemnity
Cap”). 
 (b) Owens Corning shall have no obligation to an SG Indemnified Party pursuant to Section 11.04(a) until such matters
are the subject of a written notice given by the 

  

 63 








 
Indemnified Party pursuant to Section 11.03(a) within the period following the Closing Date specified for each respective matter in Section 11.01.

 (c) Saint-Gobain shall have no liability to the OC Indemnified Parties in respect of indemnification claims pursuant to (i) breaches
of representations or warranties (as distinguished from breaches of covenants and agreements) under Section 11.02(b)(1), (ii) Section 11.02(b)(2) solely with respect to SG Environmental Matters or (iii) Section 11.02(b)(4);
in each case unless and until: 
 (i) such Damages are Recoverable Damages; and 
 (ii) such Recoverable Damages exceeds the Indemnity Threshold; provided, that if the Indemnity Threshold is reached, the entire amount of all
such Damages shall be subject to indemnification under this Section 11.04(c) up to a total of USD400,000,000 (the “SG Indemnity Cap”, together with OC Indemnity Cap, “Indemnity Caps”). 
 (d) Saint-Gobain shall have no obligation to an OC Indemnified Party pursuant to Section 11.04(c) until such matters are the subject of a written
notice given by the Indemnified Party pursuant to Section 11.03(a) within the period following the Closing Date specified for each respective matter in Section 11.01. 
 (e) Saint-Gobain shall have no liability to the OC Indemnified Parties in respect of an indemnification claim for Damages pursuant to (i) Section
11.02(b)(1) as a result of a breach of a representation under Section 4.02(n), (ii) Section 11.02(b)(2) in respect of an SG Environmental Matter or an SG Excluded Environmental Matter, (iii) Section 11.02(b)(4), or (iv) Section
11.02(b)(5) (an “OC Environmental Claim”), unless such OC Environmental Claim arises out of or relates to: (i) a specific requirement of Environmental Law to take some compliance, investigative or remedial action including
monetary payments; or (ii) a specific and formal requirement of a Governmental Authority under Environmental Law to take some compliance, investigative or remedial action, including monetary payments; (iii) a violation of Environmental Law
(A) in which there is an imminent danger or harm to the Environment or any Person, including employees or (B) which would require a compliance, investigative or remedial action, including monetary payments consistent with the practices of
a reasonable and prudent operator or (iv) a Third Party Claim other than a claim by a Governmental Authority. 
 (f) With respect to any
OC Environmental Claim arising out of or relating to the presence or Release of Hazardous Materials on or prior to the Closing Date, Saint-Gobain shall have no liability to the OC Indemnified Parties to the extent that the Damages arise primarily
out of (A) a change in use of the relevant facility after the Closing Date from an industrial use to a commercial or residential use; or (B) voluntary soil or groundwater sampling undertaken after the Closing Date at any relevant facility
that is (1) not specifically required by Environmental Laws, Environmental Permits or a Governmental Authority; (2) not undertaken in connection with maintenance, construction, renovation or expansion activities at the relevant facility
except for such sampling that would not be undertaken by a reasonable and prudent operator; (3) not undertaken in connection with (X) the proposed sale, closure, decommissioning of the relevant SG Owned Real Property or (Y) a
financing. 
  

 64 








 (g) Saint-Gobain shall have no liability to the OC Indemnified Parties to the extent that the Damages in
respect of which the OC Environmental Claim is made, relate to, result from or are increased by the closure or decommissioning of the whole or a substantial part of any site after the fourth anniversary of the Closing Date. 
 (h) Solely for the purpose of determining the amount of Damages incurred with respect to a breach of any representation or warranty, each representation
and warranty shall be read without reference to materiality or Material Adverse Effect. 
 (i) Notwithstanding anything to the contrary
contained herein, although a Party may be entitled to make a claim for indemnification pursuant to more than one provision of this Article XI, no Party shall be entitled to recover indemnification for the same claim under more than one provision of
this Article XI. 
 (j) The amount to which the Indemnified Party might otherwise be entitled under Section 11.02 shall be reduced by
the amount of any reserves made in the SG Financial Statements (or in Schedule 4.02(i)(vi)) that are readily identifiable and exclusively related to the event or events giving rise to the Indemnified Claim. 
 ARTICLE XII 
 TERMINATION

 Section 12.01 Termination. This Agreement may be terminated at any time prior to the Closing: 
 (a) by mutual written agreement of the Parties; 
 (b) by either Party if the Closing shall not have been consummated by May 31, 2008; provided, however, that neither Party may terminate this Agreement pursuant to this clause (b) if the Closing shall not have been
consummated by such date by reason of the failure of such Party to perform, or to cause its Affiliates to perform, in all material respects any of its or their respective covenants or agreements contained in this Agreement; 
 (c) by either Party if there shall be any Applicable Law that makes consummation of the Contemplated Transactions illegal or otherwise prohibited, if
consummation of the Contemplated Transactions would violate any nonappealable final order, decree or judgment of any Governmental Authority having competent jurisdiction over such Party or if a Governmental Authority has filed suit to enjoin or
otherwise prohibit the Contemplated Transactions; and 
 (d) by either Party in the event of a breach by the other Party of any
representation, warranty, covenant or agreement under this Agreement, where the effect of such breach would be to cause the conditions to the obligation to consummate the Closing of the terminating Party not to be capable of being satisfied, and
such breach is not cured by the breaching Party within 30 days of receiving written notice from the terminating Party of the breach or alleged breach, which written notice shall state that unless such breach is cured in accordance with this
Section 12.01(d) the terminating Party intends to terminate this Agreement 

  

 65 








 
(it being understood that such 30 day cure period shall not under any circumstances extend the date set forth in Section 12.01(b));

 Section 12.02 Effect of Termination. If this Agreement is terminated as permitted by Section 12.01:

(iv) this Section 12.02, (v) Section 13.03 (relating to expenses and certain Taxes), (vi) Section 13.07 (Entire Agreement), (vii) Section 13.08 (Governing Law), (viii) Section 13.14(a) (Dispute
Resolution), (ix) Section 13.15 (Consequential Damages) and (x) Section 13.16 (Performance); and 
 (b) such termination
shall be without liability of any Party (or any Affiliate, stockholder, consultant or Representative of such Party) to the other Party to this Agreement; provided, however, that if the Contemplated Transactions fail to close as a
result of a breach of any representation, warranty, covenant or agreement under this Agreement by any Party, such Party shall be fully liable for any and all damages or losses incurred or suffered by the other Party as a result of all such breaches
if the other Party is ready, willing and able to otherwise satisfy its obligations under this Agreement. 
 Section 12.03
Non-Exclusive Remedies. Notwithstanding any provision in this Article XII or elsewhere in this Agreement to the contrary, the rights and remedies provided in Section 12.02 shall be in addition to, and not exclusive of, any rights or
remedies to which the Parties may be entitled under Applicable Law as a result of a termination of this Agreement.

 Section 13.05 Disclosure. Certain information set forth in the Disclosure Schedules has been included and disclosed solely for informational
purposes and may not be required to be disclosed pursuant to the terms and conditions of this Agreement. The disclosure of any such information shall not be deemed to constitute an acknowledgement or agreement that the information is required to be
