 THIS JOINT VENTURE AGREEMENT (together with the Schedules hereto, the “JV Agreement”),
dated as of February 20, 2007, between Owens Corning Composite Coöperatief U.A. (“OC Topco”), a company organized under the Laws of The Netherlands, Owens Corning, a company organized under the Laws of Delaware (“OC
Parent”), Ondatra S.A.S., a company organized under the Laws of France (“SG Topco” and, together with OC Topco, the “Parties”), and Société de Participations Financières et
Industrielles S.A.S., a company organized under the Laws of France (“SG Parent”). 
 WITNESSETH 
 WHEREAS, the Parties, together with OC Parent and SG Parent, have entered into a Master Contribution Agreement of even date herewith (the “Master
Contribution Agreement”), which contemplates the formation of Owens Corning Vetrotex Reinforcements as a société privée à responsabilité limitée organized under the Laws of Belgium (the
“Company”) to be owned sixty percent (60%) by OC Topco and forty percent (40%) by SG Topco; 
 WHEREAS, the
Company (together with its Affiliates), when formed in accordance with this JV Agreement, shall be a joint venture company established by the Parties for the purpose of conducting the Business (as defined herein); and 
 WHEREAS, the Parties as shareholders of the Company desire to provide certain terms and conditions for the management and operations of the Joint Venture
(as defined herein); 
 NOW, THEREFORE, the parties agree as follows: 
 ARTICLE I 
 DEFINITIONS 
 1.1 Definitions. Capitalized terms used in this JV Agreement shall have the meaning specified in Schedule 1.1. 
 ARTICLE II 
 ORGANIZATION OF THE JOINT
VENTURE 
 2.1 Formation of the Company and its Subsidiaries. Prior to the Closing, the Parties shall cause the Company to be formed
as a Belgian société privée à responsabilité limitée, with a capital of EUR 18,550.00, fully paid in cash to the extent of sixty percent (60%) by OC Topco and to the extent of forty percent
(40%) by SG Topco and with the corporate charter (statuts) of the Company, substantially in the form set forth in Schedule 2.1(a) (the “Charter”). Thereafter and prior to the Closing, (i) the Parties shall
cause a Belgian société anonyme to be formed, which shall act as manager (gérant) of the Company (the “Management Company”), with a capital of EUR 61,500.00, fully paid in cash, which shall be
owned sixty percent (60%) by OC Topco and forty percent (40%) by SG Topco, and with the corporate charter (statuts), substantially in the form set forth in Schedule 2.1(b) (the “Management Company Charter”),
(ii) Owens Corning shall form a Delaware limited liability company (“US Holdco”); (iii) OC Topco shall designate OC NL Invest Coöperatief 

  

 1 

 
U.A. as “Non-US Holdco”, and (iv) the Parties shall form or cause the Company to form such other companies as are contemplated to be
organized in the Master Contribution Agreement. 
 2.2 Term. All the companies to be formed pursuant to Section 2.1 shall be
formed for an indefinite term. 
 2.3 Initial Capital Structure. On the Closing Date, the Parties shall implement the steps agreed
between them to organize the Joint Venture as described in the Master Contribution Agreement, with the result that OC Topco will own sixty percent (60%) of the Company Ownership Interests and SG Topco will own forty percent (40%) of the
Company Ownership Interests. Following the Closing, the steps set forth in Schedule 2.3 shall be implemented substantially in accordance with such Schedule. 
 2.4 Name; Principal Place of Business. The corporate name of the Company shall initially be “Owens Corning Vetrotex Reinforcements” and immediately after Closing, shall be changed to “OCV
Reinforcements”. The registered office and principal place of business of the Company shall be located in Brussels, Belgium. The principal place of business of the Company may be transferred from time to time to such other place as may be
designated by the Board of Directors. 
 2.5 Tax Treatment 
 (a) The Company and Non-US Holdco each shall be treated as a company that is resident in Belgium for Belgian Tax purposes and shall be subject to Belgian
corporate income Tax. 
 (b) The Company shall elect to be treated, and at all time shall be classified, as a partnership for United States
federal (and to the extent permitted by Law, State and Local) income Tax purposes. The Company shall not elect to be treated as a corporation for United States federal (and State and Local) income Tax purposes unless each of the Shareholders shall
consent in writing. Non-US Holdco shall be treated as a non-United States corporation for United States federal (and State and Local) income Tax purposes, and shall not elect to be treated as a partnership or disregarded entity for such purposes. US
Holdco shall be treated as a partnership or disregarded entity for United States federal income tax purposes and shall not elect to be treated as a corporation for such purposes. No Shareholder shall recognize or report any income, deduction, gain
or loss for United States federal (and State and Local) income Tax purposes on the contribution and transfer of assets by the Company to its Subsidiaries at or immediately after the Closing or any other transaction under Section 3.01 of the
Master Contribution Agreement. 
 (c) No Shareholder shall take any position on any Tax return or any Tax filing, or in any Tax audit or
proceeding, that is inconsistent with this Section 2.5. 
 (d) Each Shareholder acknowledges that reporting for financial accounting
purposes may differ from Tax treatment, and that this Section 2.5 shall not prevent any Shareholder from appropriately reporting the transactions contemplated by this JV Agreement for financial accounting purposes as required under U.S. GAAP or
IFRS. 
 (e) OC Topco shall be designated as the “tax matters partner” within the meaning of Section 6231(a)(7) of the Code
and in any similar capacity under applicable Law 

  

 2 

 
(the “Tax Matters Partner”). The Tax Matters Partner shall make or cause the Joint Venture Entities to make such elections as the Tax
Matters Partner may consider advisable for the Joint Venture Entities under any applicable Tax Law, and shall direct all Tax matters of the Company and its Subsidiaries, including the conduct of any audit or examination and the preparation of any
tax return or amended tax return, claim for refund or other filing. In this capacity, OC Topco shall (i) cause to be prepared and filed all necessary United States federal and State income Tax returns for the Company and (ii) make all
necessary or appropriate Tax elections for the Company. The Tax Matters Partner shall endeavor to discuss and confer with SG Topco regarding any decision or election related to the adoption of an accounting or depreciation method for the Company and
its Subsidiaries and shall make such decisions that are in the mutual best interest of the Shareholders. None of the Joint Venture Entities shall be obligated to pay any fees or other compensation to the Tax Matters Partner in its capacity as such.
However, the Joint Venture Entities shall reimburse the reasonable out-of-pocket expenses (including attorney, accountants and other professional fees) incurred by the Tax Matters Partner in such capacity, including the reasonable expenses
attributable to the use of internal tax, accounting and other professional staff. Except in case of fraud, gross negligence or willful misconduct on the part of the Tax Matters Partner, the Joint Venture Entities shall indemnify and hold harmless
the Tax Matters Partner from any liability attributable to the performance of its duties under this Section 2.5(e). 
 2.6 Statement
of Adhesion. As soon as possible following the incorporation of the Company, the Parties shall cause the Company to adhere to this JV Agreement by executing the undertaking set forth at the end of this JV Agreement. Upon the execution of such
undertaking, the Company shall be bound by and entitled to the benefit of any provisions herein intended to place an obligation on, or grant a right to, the Company. 
 2.7 Additional Capital Contributions. Except as expressly set forth herein, no Shareholder shall have any obligation to make any capital contribution to the Company, provided that a Shareholder may make such
additional contributions of cash or property to the Company as the Shareholder may from time to time agree to accept. No Shareholder shall be liable for the debts, liabilities, contracts or other obligations of the Company and, except as otherwise
provided in the Transaction Documents, no Shareholder shall be required to lend funds to the Company or have personal liability for the repayment of the capital contributions of the other Shareholder. 
 2.8 Maintenance of Capital Accounts. 
 (a) The Company shall establish and maintain for each Shareholder on the books of the Company an account (a “Capital Account”) pursuant to this Agreement. The Capital Account of each Shareholder shall
be increased by (i) such Shareholder’s Capital Contribution, (ii) the value (as determined for purposes of the 704 Treasury Regulations) of any property contributed to the Company (net of any liabilities secured by such property that
the Company is considered to assume, or take subject to, under Section 752 of the Code); and (iii) the amount of any Net Profits (or items of income) allocated to a Shareholder pursuant to its Company Ownership Interests, and shall be
decreased by (A) the amount of any cash distributed to a Shareholder by the Company in accordance with Section 4.3, (B) the value of any property distributed to a Shareholder by the Company (net of any liabilities secured by such
distributed property that such Shareholder is considered to assume or take subject to 

  

 3 

 
under Section 752 of the Code) and (C) the amount of any Net Losses (or item of loss or deduction) allocated to a Shareholder pursuant to
subsection (c). 
 (b) The Capital Accounts of the Shareholders shall also be adjusted appropriately for their respective
shares of any other adjustment required under Treasury Regulation Sections 1.704-1(b) and 1.704-2. 
 (c) Except as otherwise
provided in this JV Agreement, whenever it is necessary to determine the Capital Account of any Shareholder, the Capital Account of such Shareholder shall be determined after giving effect to the allocations of Net Profits, Net Losses and other
items realized prior or concurrently to such time (including, without limitation, any Net Profits and Net Losses attributable to adjustments to book values with respect to any concurrent distribution), and all contributions and distributions made
prior or concurrently to the time as of which such determination is to be made. 
 (d) In the event of a transfer of Shares in
the Company in accordance with Section 5.2 of this Agreement, the Capital Account of the transferring Shareholder shall become the capital account of the Affiliate to the extent that such Shares have been transferred. 
 (e) The provisions of this Agreement relating to the maintenance of Capital Accounts are intended to comply with Treasury Regulation
Section 1.704-1(b), and shall be interpreted and applied in a manner consistent with such Treasury Regulation. 
 2.9 Allocation of
Profits and Losses for Book and Tax Purposes. Except to the extent otherwise provided in Schedule 2.9, Net Profits and Net Losses (and if necessary, items thereof) for any Taxable Year shall be allocated among the Shareholders in
proportion to their Company Ownership Interests. 
 2.10 Withholding. The Company shall comply with tax withholding requirements under
United States federal, State and Local Law (including, without limitation, any withholding taxes pursuant to Section 1446 of the Code) and all other applicable Laws and shall remit amounts withheld to and file required forms with the applicable
authorities. 
 ARTICLE III 
 GOVERNANCE AND MANAGEMENT 
 OF THE JOINT VENTURE 
 3.1 Principles 
 (a) The Parties shall vote, or cause to be voted, their respective Ownership
Interests in the Company and in the Management Company so as to assure that the operations of the Joint Venture are conducted as if all Joint Venture Entities were a single undertaking and to give effect to the terms of this JV Agreement. The
Parties shall further procure that the members appointed by them to the governing bodies of the Company, the Management Company and the other Joint Venture Entities (whether directly or through a decision of the Board of Directors) conduct the
operations of the Joint Venture as if all Joint Venture Entities were a single undertaking and act in such a manner that this JV Agreement and any decision of the Board of Directors in accordance with Section 3.4 is performed to the fullest
extent possible. 
  

 4 

 (b) The Parties shall cause (i) the Management Company to be appointed as manager
(gérant) of the Company and (ii) the Management Company to designate the President and CEO as its permanent representative. The Management Company as manager of the Company shall, and shall cause its permanent representative to,
act in such a manner that this JV Agreement and any decision of the Board of Directors in accordance with Section 3.4 is performed to the fullest extent possible. 
 (c) The organizational documents of any newly-formed Joint Venture Entity shall be drafted in English, to the extent legally permitted. In the event of any inconsistency between the provisions of this JV Agreement and
the organizational documents of any Joint Venture Entity, the provisions of this JV Agreement shall prevail. 
 (d) Should either Party so
require, the organizational documents of any Joint Venture Entity shall be amended to reflect the governing and management principles set forth herein. 
 3.2 Composition of the Board of Directors of the Management Company; Officers of the Joint Venture 
 (a) Board of Directors. The board of directors of the Management Company (the “Board of Directors”) shall consist of five (5) members (the “Directors”), each of whom shall be appointed for a
term of three (3) years. Three (3) Directors shall be appointed from among candidates designated by OC Topco and two (2) Directors shall be appointed from among candidates designated by SG Topco. The Board of Directors shall designate
a chairman (the “Chairman”) from among the Directors designated by OC Topco, and such Chairman shall not have any special powers or responsibilities other than as set forth in this JV Agreement or the Management Company charter. The
initial Directors and the initial Chairman of the Board of Directors are listed in Schedule 3.2(a). 
 (b) Change in
Composition. Each Director may be removed, with or without cause, by the shareholders of the Management Company at the request of the Party that designated such Director. Any Director may also resign his or her position at any time by giving
written notice thereof to the other Directors. The acceptance of such resignation shall not be necessary to make it effective. In the event of a vacancy on the Board of Directors regardless of how caused, the Party that designated the Director whose
position is vacant shall have the right to designate a replacement, which shall be exercised as soon as practicable. 
 (c)
Officers. The officers of the Joint Venture shall include (i) a president and Chief Executive Officer (“President and CEO”), (ii) a Chief Financial Officer (“CFO”), (iii) a General Counsel
and (iv) any other officer as the Parties may decide is necessary. No officer needs to be a Director. Each of the officers shall be appointed for an indefinite term, and may be replaced at any time by the Board of Directors (with or without
cause). The initial President and CEO, CFO and General Counsel shall be designated by OC Topco and are listed in Schedule 3.2(c)(i). The initial appointees for all other offices shall be designated jointly by the Parties. Thereafter, the
officers of the Joint Venture shall be designated by the Board of Directors. Except for the officers set forth in Schedule 3.2(c)(ii), and unless otherwise agreed between the Parties, no officer of the Joint Venture shall continue to be an
employee, officer, director or consultant of either Party or any of their respective Affiliates. 

  

 5 

 
The Board of Directors shall fix the terms and conditions of each officer’s engagement by the Joint Venture and determine the scope of their powers.

 3.3 Meetings of the Board of Directors 
 (a) Meetings. Regular meetings of the Board of Directors shall be held at least six (6) times per year, unless otherwise agreed by the Directors, and special meetings shall be held whenever requested by
two (2) Directors. Notice of regular and special meetings of the Board of Directors shall be given to each Director, specifying the time and place of the meeting and the agenda therefor, and must be given to all Directors at least five
(5) Business Days in advance of each such meeting. Notices shall be sent by the President and CEO, shall be in writing and shall be given by hand, by facsimile or other electronic transmission method. Notice need not be given to any Director
who signs a waiver of notice (whether before or after the meeting) or who attends the meeting without protesting the lack of notice prior to its commencement. 
 (b) Location. Without prejudice to the provisions of Section 3.3(d), each meeting of the Board of Directors shall be held at the Management Company’s registered office unless another location is
specified in the notice of such meeting given in accordance with Section 3.3(a), it being understood that meetings of the Board of Directors approving the consolidated accounts of the Company, significant acquisitions and divestitures of the
Joint Venture, and the significant deviations from the Annual Budget shall be held at the Management Company’s registered office unless otherwise agreed by the Parties. 
 (c) Quorum. There shall be a quorum for the transaction of business at any meeting when at least a majority of the Directors is present or
represented and at least one Director designated by each Party is present in person; provided, however, that a quorum shall be deemed to exist if any two Directors are present at any meeting which is convened after the convening of two
consecutive meetings for which no quorum existed and with the same agenda, notice having been duly given to the Directors thereof with respect to all such meetings and at such meeting the Board of Directors may resolve on the matters set forth in
such agenda (including matters set forth in Section 3.4(b)) by a simple majority of the Directors present or duly represented. 
 (d)
Attendance at Meetings. Directors shall be entitled to vote in person or by proxy at any meeting; provided, however, that the Parties desire, insofar as practicable, that Directors attend meetings in person in order to establish
a working personal relationship among the Directors. A proxy holder needs to be another Director. Meetings of the Board of Directors may be held through the use of a videoconference, telephone conference or similar telecommunications device allowing
persons participating in the meeting to hear each other at the same time and to speak to each other. Any Director participating in a meeting by such means shall be deemed present at such meeting. 
 (e) Decisions. Each of the Directors shall be entitled to cast one vote and, except as otherwise provided in Section 3.4(b), decisions of the
Board of Directors shall be taken by simple majority vote. Decisions of the Board of Directors may validly be taken only at a meeting with respect to matters which were included in the agenda, unless at least one of the Directors designated by each
Party is present or represented and the Directors present or represented unanimously agree to extend the agenda. Any action required or permitted to be 

  

 6 

 
taken by the Board of Directors may also be taken in the form of a written consent signed by all directors. 
 (f) Compensation. Directors shall not receive any compensation for their services as Directors. All Directors shall be reimbursed by the Party or
its Affiliates that designated such Director for expenses (including travel expenses) that are incurred by such Directors in the performance of their duties as Directors (including attendance at meetings of the Board of Directors). 
 (g) Committees. Except for the matters referred to in Section 3.4(b), the Board of Directors may delegate such powers and authority to
committees established as appropriate to facilitate the operations, governance and related business activities of the Joint Venture, consistent with the terms and conditions of this JV Agreement. Such committees of the Joint Venture shall exercise
such delegated powers and authority in a manner consistent with the policies adopted from time to time by the Board of Directors. The Board of Directors shall retain the right to revoke any delegation granted hereunder at any time. 
 3.4 Actions by the Board of Directors 
 (a) The Board of Directors shall generally supervise and control the management of the operations of the Joint Venture, and shall take such actions as are contemplated to be taken by it in this JV Agreement. Without limiting the generality
of the foregoing, a resolution of the Board of Directors shall be required before any Joint Venture Entity may take (or commit to take) any of the following actions unless such action has been specifically included in the Annual Budget approved by
the Board of Directors:

 3.5 No Unauthorized Actions. 
 (a) Each Party shall use its best efforts, including through its dealings with the Directors

shall propose alternative commercial terms for the proposed arrangement. OC Topco may elect to enter 

  

 10 

 
into (or extend) the proposed arrangement on the terms so proposed by SG Topco. Whether or not OC Topco has elected to enter (or have its Affiliate enter)
into the proposed arrangement, OC Topco shall have the option to bring the dispute over the proposed terms of the contemplated arrangement, before the Unaffiliated Firm. The Unaffiliated Firm shall only consider the proposed terms that are being
disputed. The Unaffiliated Firm shall give both parties the opportunity to present their arguments in writing and shall make its determination promptly by delivering to OC Topco and SG Topco its determination of the terms that it considers to be
consistent with an arms’ length transaction, taking into account all factors that it deems relevant for his determination, without being bound by either Party’s proposed terms. The Unaffiliated Firm shall attempt to render its decision
within thirty (30) days after its commissioning by OC Topco. The Unaffiliated Firm’s decision shall, in the absence of manifest error, be final and binding upon OC Parent and SG Parent and their Affiliates, and the Parties shall cause to

and expenses shall be calculated by the Unaffiliated Firm and shall be conclusive and binding on OC Topco and SG Topco. 
 (c)
Notwithstanding Section 3.4(b), if, in the event the Board of Directors shall not approve a resolution with respect to a transaction contemplated by Section 3.4(b)(xi), then OC Topco may, in its sole discretion, elect to allow the Joint
Venture to proceed with such transaction (each such transaction, an “Overridden Acquisition”); provided that in such event, the Exit Price shall be increased by the Incremental Acquisition Debt incurred, if any, in respect of
such Overridden Acquisition. 
 (d) In the event that the OCIL Acquisition is consummated after Closing but before the End Date, the Exit
Price shall be increased by the OCIL Acquisition Debt, if any. 
 (e) In the event that the OC Korea Acquisition is consummated after Closing
but before the End Date, the Exit Price shall be increased by the OC Korea Acquisition Debt, if any. 
 3.6 Shareholders’

 (d) Shareholders may take action on a matter at a Shareholders’ meeting only if a
quorum exists. There shall be a quorum for the transaction of business at any Shareholders’ meeting when at least one representative of OC Topco and one representative 

  

 11 

 
of SG Topco are present in person or represented by a duly authorized representative; provided, however, that a quorum shall be deemed to exist
if the holders of a majority of the Shares entitled to vote at the Shareholders’ meeting are present or represented at any meeting which is convened after the convening of a prior Shareholders’ meeting for which no quorum existed and with
the same agenda, notice having been duly given to the Shareholders with respect to both of such meetings and the Shareholders’ meeting may resolve on the matters set forth in such agenda (including matters set forth in Section 3.4(b) that
have been approved by the Board of Directors in accordance with Section 3.3(c)) by a simple majority of the Shareholders present or represented. 
 (e) Each Shareholder shall be entitled to cast one vote for each Share that is held by such Shareholder with respect to each matter voted on by the Shareholders. Unless otherwise required by applicable Law, all
decisions of the Shareholders shall be made by the affirmative vote of the holders of a majority of the Shares present and eligible to cast a vote with respect to such decision. Decisions of the Shareholders may be validly made only at a
Shareholders’ meeting with respect to matters that were included in the agenda, unless representatives of both Parties are present and the Shareholders present unanimously agree to extend the agenda. 
 (f) To the extent that any of the matters set forth in Section 3.4(b) requires a vote by the meeting of shareholders of any Joint Venture Entity, no
such matter shall be brought before the shareholders’ meeting of the relevant Joint Venture Entity unless it has been approved by the Board of Directors in accordance with this Article III. Where applicable, OC Topco and SG Topco each
undertakes to exercise its vote as a Shareholder of the Company in order to implement the decisions of the Board of Directors in accordance with this Article III.

without the approval of the Board of Directors. 
 (b) The Annual Budget shall include, but not be limited to, the following:

	 	(v)	a description of key R&D developments (including the new products portion of total sales). 

 (c) If the Board of Directors does not approve the Annual Budget for any Fiscal Year prior to the commencement of such Fiscal Year, then the Annual
Budget approved by the Board of Directors for the previous Fiscal Year will be deemed to be the Annual Budget for the current Fiscal Year until such time as the Board of Directors approves the Annual Budget for the current Fiscal Year. 

(d) Together with the Annual Budget, the officers of the Joint Venture shall also prepare and submit to the Board of Directors for its approval a
projection of the Joint Venture’s operating results for the three (3) upcoming Fiscal Years, including pro forma consolidated income statements, balance sheets and statements of cash flows with appropriate details describing sales growth
(including as a result of potential acquisitions) or decline (including as result of potential divestments or closures of plants or facilities), manufacturing cost change, change in operating expenses, projected investments, context of industry
health and competitiveness, vision for technology and commercial developments and future initiatives and plans of the Joint Venture.

 (a) From and after the Closing Date until the third (3rd) anniversary of the date on which a Party or any of its Affiliates ceases to be a Shareholder, the Parties shall not, and shall cause their respective
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 any Joint Venture Entity or the Business;
provided, however, that either Party or their Affiliates may own a non-Controlling 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. 
 (b) Section 6.1(a) shall not apply to any business owned as of the date hereof by either an SG
Party or an OC Party that the Parties have agreed shall not be contributed to the Joint Venture (including, for the avoidance of doubt, to the SG Textile Solutions Business), provided, however, that any such business shall not manufacture or sell
any Company Products (as defined in the Master Contribution Agreement) except pursuant to a written supply, license, and/or tolling agreement with the Company or its Affiliates. 
 (c) Section 6.1(a) shall not prohibit the acquisition, directly or indirectly, by either Party or any of its Affiliates, of any business assets or
shares which cause it to be in breach of Section 6.1(a) (the “Prohibited Asset”) as the result of the consummation of any merger, acquisition or similar transaction for so long as and provided that (i) the annual sales
revenue generated by the Prohibited Asset represents less than ten (10) percent of the total annual sales revenue generated by such acquired business assets or shares, or (ii) the annual sales revenue generated by the Prohibited Asset is
less than USD twenty (20) million, in each case calculated based on the relevant annual financial statements for the most recent complete financial year. 
 (d) If either Party or any of its Affiliates becomes the owner of any Prohibited Asset at any time such Party or any of its Affiliates is a Shareholder, such Party shall Transfer or cause its Affiliate to Transfer
such Prohibited Asset to a Third Party for cash consideration only and shall use its reasonable efforts to effect such Transfer within twelve (12) months after its acquisition (and if such Transfer does not occur within such twelve
(12) month period, such Party shall continue to use its reasonable efforts to effect such Transfer as soon as practically possible), which Transfer will be subject, however, to a right of first refusal in favor of the Company or any Joint
Venture Entity designated by the Company, which right of first refusal shall be exercised in accordance with Section 6.1(e). 
 (e)
Promptly but no later than five (5) Business Days after the Party or its Affiliate who acquired the Prohibited Asset has received a written bona fide offer from a Third Party to purchase such Prohibited Asset, such Party (the
“Transferor”) shall give written notice (a “Transferor’s Notice”) to the Company with a copy to the other Party of its or its Affiliate intention to sell the Prohibited Asset, which notice shall
(i) identify the 

  

 19 

 
Prohibited Asset, (ii) identify the proposed Third Party transferee and any other material items and conditions of the proposed Transfer and
(iii) attach a copy of the bona fide offer. The date on which such Transferor’s Notice is actually received by the Company and the other Party, whichever is earlier, is referred to hereinafter as the “Notice Date.” The
Company shall have sixty (60) days following the Notice Date to notify the Transferor in writing whether the Company (or any Joint Venture Entity) wishes to buy such Prohibited Asset on the same terms as set forth in the Transferor’s
Notice (the “ROFR Notice”). If the Company either fails to give the ROFR Notice within such sixty (60) day period or notifies the Transferor that it does not wish to purchase the Prohibited Asset, the Company shall be deemed to
have declined to purchase such Prohibited Asset and the Transferor may thereafter transfer, or have its Affiliate transfer, to the proposed transferee identified in the Transferor’s Notice at any time within thirty (30) days after
(i) receipt of all necessary approvals from any Governmental Authority or (ii) if no such approvals are necessary, after the expiration of such sixty (60) day period, all (but not less than all) of the Prohibited Asset at a price and
on terms and conditions which are not more favorable to the proposed transferee than those set forth in the Transferor’s Notice; provided that if the Prohibited Asset is not transferred to the proposed transferee for any reason within
such period, then such Prohibited Asset may be transferred only by again complying with all of the terms and procedures set forth in this Section 6.1. If the Company does provide an ROFR Notice to the Transferor within such sixty (60) day
period, such ROFR Notice shall be deemed to create a binding agreement between the Transferor or its applicable Affiliate and the Company (or the applicable Joint Venture Entity designated by the Company in the ROFR Notice) to Transfer, subject to
the receipt of the purchase price all and not less than all of the Prohibited Asset at the price and on the other terms and conditions set forth in the Transferor’s Notice. The Transferor or its applicable Affiliate shall be liable for the
Transfer of full and unencumbered legal title to the Prohibited Asset. The closing for the Transfer to the Company or the designated Joint Venture Entity shall take place at a time and place reasonably acceptable to the Transferor or its applicable
Affiliate and the Company or the designated Joint Venture Entity; provided that such closing shall occur on the later of (i) thirty (30) days after the receipt of all necessary approvals from any Governmental Authority and
(ii) one hundred and eighty (180) days after receipt by the Transferor of the ROFR Notice. Each of the Transferor or its applicable Affiliate, on the one hand, and the Company or the designated Joint Venture Entity, on the other hand,
shall pay its own costs and expenses in connection with the transaction. 
 (f) If either Party or any of its Affiliates becomes the owner of
any Prohibited Asset at any time during the three (3) years after such Party or any of its Affiliates ceases to be a Shareholder, such Party shall Transfer or cause its Affiliate to Transfer such Prohibited Asset to a Third Party for cash
consideration only, which Transfer will be subject, however, to a right of first offer in favor of the Company or any Joint Venture Entity designated by the Company, which right of first offer shall be exercised in accordance with
Section 6.1(g). 
 (g) Promptly but no later than twenty (20) Business Days following the acquisition of the Prohibited Asset by
the acquiring Party or any of its Affiliates, such Party (the “ROFO Transferor”) shall give written notice (a “ROFO Transferor’s Notice”) to the Company with a copy to the other Party of its intention, or that
of its applicable Affiliate, to sell the Prohibited Asset, which notice shall (i) identify the Prohibited Asset, (ii) indicate the expected purchase price of the Prohibited Asset and any other material items and conditions of the proposed
Transfer and (iii) attach a copy of any due diligence report prepared by the 

  

 20 

 
ROFO Transferor or its applicable Affiliate and its legal and financial advisors (but only to the extent permitted by such legal and financial advisors) for
the purpose of the transaction comprising the Prohibited Asset. The date on which such ROFO Transferor’s Notice is actually received by the Company is referred to hereinafter as the “ROFO Notice Date.” The Company shall have
sixty (60) days following the ROFO Notice Date to notify the ROFO Transferor in writing whether the Company (or any Joint Venture Entity) wishes to buy such Prohibited Asset on the same terms as set forth in the ROFO Transferor’s Notice
(the “ROFO Notice”). If the Company either fails to give the ROFO Notice within such sixty (60) day period or notifies the ROFO Transferor that it does not wish to purchase the Prohibited Asset, the Company shall be deemed to
have declined to purchase such Prohibited Asset and the ROFO Transferor or its applicable Affiliate may thereafter transfer the Prohibited Asset to any third party at a price and on terms and conditions which are not more favorable to the proposed
transferee than those set forth in the ROFO Transferor’s Notice; provided that if the Prohibited Asset is not transferred for any reason before the end of a one hundred and eighty (180) day period following the expiry of the
above-mentioned sixty (60) day period (or, if applicable, within thirty (30) days after receipt of all necessary approvals from any Governmental Authority, provided a binding agreement (subject only to customary conditions, including
regulatory approvals) shall have been entered into between the ROFO Transferor or its applicable Affiliate and the relevant Third Party purchaser before the end of the above-mentioned one hundred and eighty (180) day period), then such
Prohibited Asset may be transferred only by again complying with all of the terms and procedures set forth in this Section 6.1. If the Company does provide a ROFO Notice to the ROFO Transferor within such sixty (60) day period, such ROFO
Notice shall be deemed to create a binding agreement between the ROFO Transferor or its applicable Affiliate and the Company (or the applicable Joint Venture Entity designated by the Company in the ROFO Notice) to Transfer, subject to the receipt of
the purchase price, all and not less than all of the Prohibited Asset at the price and on the other terms and conditions set forth in the ROFO Transferor’s Notice. The ROFO Transferor or its applicable Affiliate shall be liable for the Transfer
of full and unencumbered legal title to the Prohibited Asset. The closing for the Transfer to the Company or the designated Joint Venture Entity shall take place at a time and place reasonably acceptable to the Transferor or its applicable Affiliate
and the Company or the designated Joint Venture Entity; provided that such closing shall occur on the later of (i) thirty (30) days after the receipt of all necessary approvals from any Governmental Authority and (ii) one
hundred and eighty (180) days after receipt by the Transferor of the ROFO Notice. Each of the ROFO Transferor or its applicable Affiliate, on the one hand, and the Company or the designated Joint Venture Entity, on the other hand, shall pay its
own costs and expenses in connection with the transaction. 
 (h) Any decision by the Board of Directors to purchase any Prohibited Asset
from SG Topco or any of its Affiliates while SG Topco or any of its Affiliates is a Shareholder shall be taken by simple majority vote, notwithstanding the provisions of Section 3.4(b). 
 6.2 Non-solicitation of Certain Employees 
 (a) From and after the Closing Date until the second (2nd) anniversary of the date on which a Party or any of its Affiliates ceases to be a Shareholder, the Parties shall not, and shall cause their
respective Affiliates not to, without the prior written approval of the other Party, directly or indirectly solicit any individual who is a JV Employee to terminate his 

  

 21 

 
or her employment relationship with the relevant Joint Venture Entity; provided, however, that the foregoing shall not apply to any JV Employee
hired as a result of the use of an independent employment agency (so long as the agency was not directed to solicit a particular individual or a class of individuals that could only be satisfied by employees of the Joint Venture) or as a result of
the use of advertisements and other general solicitation (such as an advertisement in newspapers, on either Party’s websites or internet job sites, or on radio or television) not specifically directed to JV Employees. 
 (b) From and after the Closing Date until the second (2nd) anniversary of the Closing Date, the Company shall not, and shall cause any Joint Venture Entity not to, without the prior written approval of
the applicable Party, directly or indirectly solicit any individual who is employed by either Party or any of their Affiliates, to terminate his or her employment relationship with such Party or its Affiliates, as the case may be; provided,
however, that the foregoing shall not apply to individuals hired as a result of the use of an independent employment agency (so long as the agency was not directed to solicit a particular individual or a class of individuals that could only
be satisfied by employees of either Party or any of their Affiliates) or as a result of the use of advertisements and other general solicitation (such as an advertisement in newspapers, on Company websites or internet job sites, or on radio or
television) not specifically directed to employees of either Party or any of their Affiliates. 
 6.3 Confidentiality. For a period
commencing on the Closing Date and ending ten (10) years after termination of this JV Agreement, each Party shall, and shall cause its Affiliates and each Joint Venture Entity to, treat and hold as confidential, any and all technical,
economic, financial, or marketing information or other proprietary or confidential information acquired from the other Party, its respective Affiliates or any Joint Venture Entity. In the event any Party or Joint Venture Entity is requested or
required (by oral or written request for information or documents in any legal proceeding, interrogatory, subpoena, civil investigative demand or similar process or by applicable Law) to disclose any such confidential or proprietary information,
then such Party shall notify the other Party or the Company, or the Company will notify both Parties, as applicable, promptly of the request or requirement so that the other Party, the Parties or the Company, as applicable, at their own expense, may
seek an appropriate protective order or waive compliance with this Section 6.3. If, in the absence of a protective order or receipt of a waiver hereunder, a Party or a Joint Venture Entity is, on the advice of counsel, compelled to disclose
such confidential information, such Party or Joint Venture Entity may so disclose the confidential or proprietary information; provided that such Party or Joint Venture Entity shall use reasonable efforts to obtain reliable assurance that
confidential treatment shall be accorded to such confidential or proprietary information. The provisions of this Section 6.3 shall not be deemed to prohibit the disclosure by either Party or any Joint Venture Entity of confidential or
proprietary information relating to the operations or affairs of its 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 the Company in accordance
with the terms and conditions of any of the Transaction Documents, (vi) in connection with asserting any rights or remedies or performing any obligations under this JV Agreement or any of the Transaction Documents, or (vii) in connection
with any other similar administrative functions in the ordinary course of business; provided that in each such case 

  

 22 

 
such Party or Joint Venture Entity shall use reasonable efforts to obtain reliable assurance that confidential treatment shall be accorded to such
confidential or proprietary information. Notwithstanding the foregoing, the provisions of this Section 6.3 shall not apply to information that (x) is or becomes publicly available other than as a result of a disclosure by the Party or
Joint Venture Entity required to keep the information confidential, (y) is or becomes available to a Party or Joint Venture Entity on a non-confidential basis from a source that, to the knowledge of such Party or Joint Venture Entity, is not
prohibited from disclosing such information by a legal, contractual or fiduciary obligation, or (z) is or has been independently developed by the Party or Joint Venture Entity required to keep the information confidential as evidenced by
written documentation. 
 ARTICLE VII 
 TERMINATION OF THE JV AGREEMENT 
 7.1 Termination. The JV Agreement shall terminate on the earliest
of the following dates: 
 (a) at such time as either Party, their successors or their Affiliates shall cease to have an Ownership Interest
in the Company; 
 (b) upon notice from either Party to the other Party, if the Closing shall not have been consummated by December 31,
2007; provided, however, that neither Party may terminate this JV 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 or its Affiliates to
perform, in all material respects, any of its or their respective covenants or agreements contained in any Transaction Document; 
 (c) on the tenth (10th) anniversary of the Closing Date. 
 7.2

Shareholders’ Capital Accounts, after giving effect to all contributions, distributions and allocations for all periods. It is the intention of the parties that, after accounting for all allocations provided for in Schedule 2.9, the
Shareholders will receive liquidating distributions in accordance with their Ownership Interests in the Company. 
 ARTICLE VIII

 SETTLEMENT OF DISPUTES 
 8.1
Dispute Resolution. If there shall be any dispute, controversy or claim (“Dispute”) between an SG Party and an OC Party arising out of, relating to, or connected with this JV Agreement, the breach, termination or invalidity
hereof, or the provisions contained herein or omitted herefrom, the parties shall use their best efforts to resolve the 

  

 23 

 
matter on an amicable basis and in a manner fair and equitable to the parties. If an SG Party notifies an OC Party or vice-versa that a Dispute has arisen
and the parties are unable to resolve such Dispute within thirty (30) days from such notice, then the matter shall be referred to the Chief Executive Officer of OC Parent and the Président, HPM Division of Saint-Gobain, who shall act by
mutual agreement on all such matters. No recourse to arbitration under this JV Agreement shall take place unless and until such representatives of the parties have been unable to resolve the Dispute within thirty (30) days after the expiration
of the thirty (30) day period referred to above. 
 8.2 Arbitration. The parties irrevocably agree that any Disputes (other than
as provided in Section 3.5(b)) that are not resolved in accordance with Section 8.1 within the two thirty (30) day periods mentioned therein shall be finally settled by arbitration in Brussels, by three arbitrators appointed and
proceeding in accordance with the Rules of Arbitration (the “ICC Rules”) of the International Chamber of Commerce (the “ICC”) as the exclusive means of resolving such Disputes. For purposes of appointing such
arbitrators, SG Parent and its Affiliate shall constitute one party and OC Parent and its Affiliates shall constitute another party. For purposes of appointing such arbitrators, in the event that there are only two parties to a Dispute, each party
shall appoint one arbitrator and either the third arbitrator shall be selected by the two party-appointed arbitrators or, failing agreement within thirty (30) days after the party-appointed arbitrators have been confirmed, by the ICC in
accordance with the ICC Rules. In the event that there are more than two parties to a Dispute, the arbitrators shall be appointed in accordance with the ICC Rules. All submissions and awards in relation to arbitration under this JV Agreement shall
be made in English and all arbitration proceedings and all pleadings shall be in English. For purposes of this Section 8.2, the term “party to a Dispute” may include groups of aligned parties. 
 8.3 Confidentiality of the Arbitration. Except as may be required by applicable Law, stock exchange rules, Governmental Authorities, or in
connection with the ordinary course operation of the Business, the parties agree to maintain confidentiality as to all aspects of the arbitration, including its existence and results, except that nothing herein shall prevent any party from
disclosing information regarding the arbitration for purposes of enforcing the judgment of the arbitral tribunal or in any court proceedings involving the parties. The parties further agree to obtain the arbitral tribunal’s agreement to
preserve the confidentiality of the arbitration.

direct or indirect wholly owned domestic Subsidiary of the assignor, delegator or transferor, as the case may be, the exception set forth in this clause shall no longer apply and such assignment, delegation or transfer shall be void unless otherwise
permitted under this Section 9.3). Notwithstanding the foregoing, no assignment, delegation or other transfer of rights under this JV Agreement shall relieve the assignor of any liability or obligation hereunder. Any attempted assignment,
delegation or transfer in violation of this Section 9.3 (or Section 5.2) shall be void.

including the performance premium, if applicable, the Management Company Price and the Target Price shall have been determined in accordance with the 

  

 5

 (h) If the transfer of the Ownership Interests in SG Topco pursuant to an Option is subject to the

under Section 2.5 or (D) the Ownership Interests held by SG Parent in SG Topco are not free and clear of all rights of pledges, liens, options or other encumbrances as of the Exit Date, then OC Topco shall have the option to
purchase the Ownership Interests owned by SG Topco in the Company and the Management Company instead of the Ownership Interests owned by SG Parent in SG Topco, for the same consideration less the Target Price, and SG Topco hereby grants such option
right to OC Topco. In the event OC Topco exercises such option right, (i) if there are any SG Shortfall Shareholder Loans, SG Topco shall, together with its Ownership Interests in the Company and the Management Company, transfer, for no
additional consideration, all rights and interests in such SG Shortfall Shareholder Loans (including the accrued unpaid interest thereon through the Exit Date), if any and (ii) if there is a SG Excess Shareholder Loan, SG Topco shall repay the

through the Exit Date). The relevant provisions of this Article III shall be read in such a case as referring to the Ownership Interests of the Company and the Management Company rather than the Ownership Interests of SG Topco.

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