Notwithstanding anything to the contrary in this Agreement, this Agreement shall not constitute an agreement to sell, assign or transfer any Transferred Asset, or any claim, right or benefit arising under or resulting from any Transferred Asset, to the Asset Buyer, if an attempted sale, assignment or transfer thereof, without novation or the prior consent, approval, authorization, waiver or agreement of another Person (a “Third Party Consent”), would (i) violate or is otherwise prohibited under any applicable Law, (ii) constitute a breach or other contravention of the rights of a third party, (iii) be ineffective with respect to any party to an agreement concerning such asset, or (iv) in any way adversely affect the rights thereunder of the Asset Seller or, upon transfer, of the Asset Buyer, as the case may be (the “Non-Assignable Items”).

With respect to the Contracts and assets listed in Schedule 1.5.2 (which are Material Contracts, other material Contracts or material Transferred Assets) (i) which are Non-Assignable Items, or (ii) in respect of which the consummation of the transactions contemplated hereby would violate or result in the breach or termination thereof, constitute a default or an event of default

(a)    the Sellers shall (at the Sellers' cost and expense) use their commercially reasonable efforts to obtain, prior to the Closing, all Third Party Consents necessary to authorize, approve or permit the sale, assignment, transfer or continuation of such Consent Items (the “Material Consents”) to or with the Buyers (including for the purposes hereof at the Buyers' sole discretion, the Business) or to otherwise novate such Consent Items for the benefit of the Buyers (or the Business), provided that:

(i)    in soliciting the Material Consents or novations, the Sellers’ Group shall, as applicable and upon Buyers' prior written consent, which shall not be unreasonably withheld or delayed, provide such relevant disclosure of the transactions contemplated hereby to the relevant third parties as may be reasonably required;

(ii)    Buyers shall reasonably assist and cooperate in good faith with the Sellers’ Group to obtain the Material Consents or novations by providing any information or otherwise taking any actions which the Sellers’ Group may reasonably request; and

(b)    in the event that any Material Consent or novation is not obtained on or prior to Closing, the Sellers’ Group shall:

(i)    continue to use commercially reasonable efforts (on the basis described above) to obtain such Material Consent or novation until the earlier of (x) the date which is three (3) months after the Closing Date, (y) the date of expiration of the relevant Consent Item (provided that the Sellers’ Group shall not be obligated to extend the stated term of the relevant Consent Item, including pursuant to any available renewal option), and (z) the termination by the relevant third party of the relevant Consent Item; and

(ii)    cooperate in good faith with the Buyers to put in place, to the extent permitted by Law or the terms of the respective Consent Item, such arrangements as the Sellers and the Buyers may, acting in good faith, find with respect to such Consent Item (which arrangements may include entering into subleases or subcontracts with, or acting as agent for, the Buyers or the Business), in order to provide to the Buyers or the Business to the fullest extent practicable and legally feasible subject to the performance by the Buyers and the Business (at the Buyers’ sole expense) of all applicable obligations thereunder arising after Closing, benefits reasonably equivalent to obtaining the Material Consent, until the earlier of (x) the termination of the relevant Consent Item by the relevant members of the Sellers’ Group; provided, however, that the Sellers’ Group shall have the right to terminate the respective Consent Item at the earliest date permitted under such Consent Item subject to reasonable notice to the Buyers, but in no event earlier than three (3) months after the Closing Date, (y) the date of expiration of the relevant Consent Item (provided that no Seller shall be obligated to extend the stated term of the relevant Consent Item, including pursuant to any available automatic renewal option), and (z) the termination by the

relevant third party of the respective Consent Item.

(a)    After Closing, the Asset Buyer shall be solely responsible for any ongoing work required to be carried out pursuant to or in respect of any bids, tenders or sales or service proposals of the Asset Seller in relation to the Business which are outstanding on or prior to the Closing Date and which, if accepted, will constitute a contract binding on the Asset Seller as set forth in Schedule 1.5.3 (the “Tenders”). The Asset Seller and the Asset Buyer will cooperate and use their respective commercially reasonable efforts to notify promptly the person who invited to any Tender and to obtain, as soon as possible after Closing, to the extent required, any third party consent for any obligations or ongoing work in relation to the Tenders to be carried out by the Asset Buyer after Closing. If any such third party consent is not obtained in respect of a Tender within three (3) months after Closing, the Asset Seller shall, in its sole and absolute discretion, be entitled to withdraw or terminate such Tender.

(b)    For the avoidance of doubt, insofar as any Tender is accepted and becomes a binding contract of the Asset Seller prior to Closing, the provisions of Sections 1.5.1 and 1.5.2 shall apply to such contracts.

(a)    Not later than four (4) Business Days before the Closing Date, for the purpose of calculating the Unadjusted Purchase Price pursuant to Section 2.1(c), Sellers’ Representative shall deliver to the Buyers (i) a statement with the calculation and the amount of each of the Estimated Closing Indebtedness (detailing the Estimated Closing Indebtedness Liabilities, the Estimated Closing Indebtedness Assets and the Estimated Closing Cash, each shown in Euro-amounts) and the Estimated Closing Working Capital and (ii) a balance sheet prepared in the same manner as the Closing Accounts, from which the Estimated Closing Indebtedness and the Estimated Closing Working Capital have been determined.

(b)    The aggregate cash consideration to be paid for the Acquired Interests shall be (i) equal to seventy nine million five hundred twenty six thousand four hundred U.S.-Dollars (USD 79,526,400) (the “Purchase Price”), (ii) subject to adjustment in accordance with Section 2.2 hereof and (iii) paid by the Buyers to the Sellers in accordance with Sections 2.1(c) and 2.3.

(c)    At the Closing, the Buyers shall pay to the Sellers in immediately available funds:

(i)    in U.S. Dollars, an amount equal to the result of (A) the Purchase Price, (B) minus the Estimated Closing Indebtedness Liabilities (to be converted into U.S. Dollars at the Conversion Rate), and (C) as the case may be, (x) minus the amount by which the Estimated Closing Working Capital is less than the Target Working Capital or (y) plus the amount by which the Estimated Closing Working Capital exceeds the Target Working Capital, (in each case of (x) or (y), such amount to be converted into U.S. Dollars at the Conversion Rate); and

(ii)    in Euros, an amount equal to the result of (A) the Estimated Closing Cash

plus (B) the Estimated Closing Indebtedness Assets (the aggregate amount resulting from (i) plus (ii) shall be referred to as the “Unadjusted Purchase Price”).

(d)    The Unadjusted Purchase Price shall be allocated among the Acquired Interests in accordance with Schedule 2.1(d).

(a)    As soon as practicable, but in no event later than sixty (60) calendar days after the Closing Date, the Sellers’ Representative shall prepare and deliver to the Buyers the Closing Accounts. On the basis of the Closing Accounts, and concurrently with the delivery thereof to the Buyers, Sellers’ Representative shall provide the Buyers with: (i) a statement containing a calculation of the Indebtedness as of the Closing Date determined in accordance with the Methodologies (the “Closing Indebtedness Statement”); (ii) a statement containing a calculation of the Closing Working Capital determined in accordance with the Methodologies (the “Closing Working Capital Statement”); (iii) a statement containing a calculation of the Adjustment Amount (as hereinafter defined), if any; and (iv) a written statement by KMPG that the Closing Accounts, the Closing Indebtedness Statement and the Closing Working Capital Statement have been prepared in accordance with the Methodologies and consistent with the statement and the balance sheet referred to in Section 2.1(a). The Closing Indebtedness Statement and the Closing Working Capital Statement shall be collectively referred to as the “Closing Statements”.

(b)    Cooperation. The Buyers shall, and shall cause the statutory auditors and other advisors of the Business after Closing to reasonably cooperate and respond to questions and requests for information submitted by the Sellers or their representatives necessary for the preparation of the Closing Accounts and the Closing Statements. After having received a reasonable prior notice, the Buyers shall, and shall cause the statutory auditors of the Business, to provide Sellers or their representatives with access, at normal business hours and at Sellers' own expense, to Buyers' representatives and to all books and records to the extent related to the Transferred Companies, the Transferred Assets, the Assumed Liabilities and the Business, for the preparation and review of the Closing Accounts and Closing Statements.

(a)    The Buyers shall, within thirty (30) Business Days from the date of the submission of the Closing Accounts and the Closing Statements (the “Review Period”), complete, at their own costs and expenses, their review thereof and notify the Sellers’ Representative in writing of its objection(s) to any of the Closing Accounts and Closing Statements (the “Objection”). Any Objection can be based only upon an error in the Closing Accounts or in the Closing Statements or failure to comply with Section 2.2.1, in each case where such error or failure affects the calculation set forth in the Closing Statements. Any Objection shall set forth a specific and reasonably detailed description of the items and amounts contested in such Objection (the “Disputed Items”), the revisions to the Closing Accounts and/or Closing Statements which the Buyers believe should be made, and Buyers' calculation, if any, of the Adjustment Amount. The Buyers shall be deemed to have accepted any items not specifically disputed in the Objection and, after expiry of the Review Period, shall not be entitled to (i) raise new items or (ii) modify the nature or amount of the Disputed Items set out in an Objection. Failure to so notify Sellers’ Representative within the Review Period shall constitute acceptance and approval of the Closing Accounts and the Closing Statements, which shall become

final and binding upon the Sellers and the Buyers.

(b)    If within fifteen (15) Business Days after the submission by Buyers of any Objection (the “Negotiation Period”), the Buyers and Sellers’ Representative are unable to resolve all the Disputed Items after using their good faith efforts to reach a resolution, they shall submit the unresolved Disputed Items to the office of PricewaterhouseCoopers in Frankfurt am Main, Germany, or, if PricewaterhouseCoopers is unwilling or cannot accept its mission, to another internationally recognized firm of independent public accountants as to which Sellers’ Representative and the Buyers mutually agree (in each case the “Independent Accounting Firm”). If Sellers’ Representative and the Buyers cannot agree on an alternative independent accounting firm within five (5) Business Days after the end of the Negotiation Period, each of Sellers’ Representative or the Buyers shall be entitled to request the designation of such firm by the President of the Chamber of Industry and Commerce in Düsseldorf.

(c)    Promptly after determination of the Independent Accounting Firm, Buyers and/or Sellers’ Representative shall each submit a written statement on the unresolved Disputed Items together with the relevant documentation in relation thereto to the Independent Accounting Firm. The Buyers and Sellers’ Representative shall cause that the Independent Accounting Firm be provided with any other information and documentation that it may reasonably request as soon as reasonably practicable. The Buyers and Sellers’ Representative shall instruct the Independent Accounting Firm to act as expert in accounting and not as an arbitrator, and to limit its examination to the unresolved Disputed Items. The Independent Accounting Firm shall (x) give the Parties a reasonable opportunity to provide written and oral submissions to it; (y) require that the Parties provide to each other a copy of any written submissions at the same time as they are made to the Independent Accounting Firm; and (z) allow each Party to be present while oral submissions are being made by any other Party. The Buyers and Sellers’ Representative shall request the Independent Accounting Firm to use its best efforts to deliver a preliminary report setting forth its resolution and, if applicable, its calculation of the Disputed Items, as promptly as practicable, but no later than thirty (30) calendar days following its appointment. The Buyers and Sellers’ Representative shall have the opportunity to provide comments to the Independent Accounting Firm regarding the preliminary report within fourteen (14) calendar days from the date of such preliminary report (and such comments shall be communicated forthwith to the respective other Party). The Independent Accounting Firm shall deliver a final written report within sixty (60) calendar days following its appointment. The determination of the unresolved Disputed Items by the Independent Accounting Firm in its preliminary and final reports shall state which adjustments should be made to the Closing Statements (including a calculation of the resulting Adjustment Amount, if any), and shall be delivered to Sellers’ Representative and the Buyers as promptly as practicable. The determination in the Independent Accounting Firm’s final report shall be final, conclusive and binding upon the Sellers and the Buyers, except in the event of manifest error. The Buyers and Sellers’ Representative shall, and shall procure that their accountants and other advisers shall, and shall instruct the Independent Accounting Firm to keep all information and documents provided to them pursuant to this Section confidential and not use the same for any purpose, except in connection with the preparation of the Closing Statements or the resolution of the Disputed Items. The fees and expenses of the Independent Accounting Firm and the expert proceedings shall be initially advanced and shared equally between the Sellers, on the one hand, and the Buyers, on the other hand (i.e., 50/50). The Independent Accounting Firm shall ultimately decide in its reasonable discretion (billiges Ermessen) having regard to its decision and the original points of view and requests of the Parties pursuant to section 91 of the German Code of Civil Procedure (Zivilprozessordnung – ZPO) regarding the allocation of its fees and expenses and the costs of the expert proceedings, including reasonable fees and expenses of the Parties for their advisors.

(d)    The Closing Accounts and the Closing Statements (i) to which Buyers do not object in accordance with Section 2.2.2(a), or (ii) as to which the Buyers and Sellers’ Representative agree, or (iii) as otherwise conclusively and bindingly determined in accordance with Section 2.2.2(c) shall be referred to as the “Final Closing Accounts” and the “Final Closing Statements”, respectively.

(a)    If and to the extent the Closing Working Capital as set forth in the Final Closing Statements (the “Final Working Capital”), is greater or less than the Estimated Closing Working Capital, the following adjustments shall be made:

(i)    If the Final Working Capital is less than the Estimated Closing Working Capital and such shortfall exceeds the amount of EUR 150,000, the Share Seller shall pay to the Share Buyer the entire amount of the shortfall.

(ii)    If the Final Working Capital is greater than the Estimated Closing Working Capital and such excess is greater than EUR 150,000, the Share Buyer shall pay to the Share Seller the entire amount of such excess.

(b)    If and to the extent the Indebtedness as set forth in the Final Closing Statements (the “Final Indebtedness”) is greater or less than the Estimated Closing Indebtedness, the following adjustments shall be made:

(i)    To the extent that the Final Indebtedness is less than the Estimated Closing Indebtedness, an amount equal to such shortfall shall be paid by Share Buyer to the Share Seller.

(ii)    To the extent that the Final Indebtedness is greater than the Estimated Closing Indebtedness, an amount equal to such excess shall be paid by the Share Seller to Share Buyer.

(c)    All amounts payable by the Share Buyer or the Share Seller, as the case may be, pursuant to this Section 2.2.3 shall be netted against all amounts payable to such Party by the other Parties pursuant to this Section 2.2.3 and the resulting net aggregate of such adjustments shall be referred to as the “Adjustment Amount”.

(d)    The Adjustment Amount shall be paid in immediately available funds within seven (7) calendar days following the determination of the Final Closing Accounts and the Final Closing Statements, and shall bear interest from the Closing Date through and including the date of actual payment at a rate equal to two percent (2%) per annum.

(e)    The Unadjusted Purchase Price plus or less, as the case may be, the Adjustment Amount, shall be referred to as the “Final Purchase Price”.

(f)    Allocation of Adjustment Amount. The Adjustment Amount shall be allocated among the Acquired Interests in accordance with Schedule 2.2.3(f). The allocation to the individual Transferred Assets to be acquired from the Asset Seller shall be based on the fair market value of each such Transferred Asset. The allocation shall be agreed between the Asset Seller and the Asset Buyer.

(g)    To the extent any Adjustment Amount shall be payable, the Parties shall in no event

be entitled to set-off such Adjustment Amount against any amount otherwise payable under this Agreement by the respective other Party, including without limitation any indemnity payable under Section 11.1 or Section 11.2 hereof.

The payment of the Unadjusted Purchase Price shall be made in accordance with Section 2.1(c), and the payment of the Adjustment Amount shall be made in Euros, in each case by irrevocable wire transfer in immediately available funds to such bank account as the recipient shall designate in writing at the latest ten (10) Business Days prior to the date when such payment becomes due. If not paid in a timely fashion, any sums due and payable under this Agreement shall bear interest at a rate equal to five percent (5%) per annum from and including the day payment was due through and including the day payment is made. For the avoidance of doubt, any interest pursuant to the preceding sentence shall be payable in addition to the interest set forth in Section 2.2.3(d) above.

The Parties agree that the Sellers’ Guarantees shall neither be qualified or construed as agreements on quality (Beschaffenheitsvereinbarungen) within the meaning of Section 434 para. 1 of the BGB nor quality guarantees concerning the object of the purchase (Garantien für die Beschaffenheit der Sache) within the meaning of Section 443, 444 of the BGB. Section 442 para. 1 of the BGB shall not apply; however, Section 11.9(a) of this Agreement shall be applicable.

Each Seller and each Transferred Company is a legal entity duly organized, validly existing and (where relevant) in good standing under the Laws of the jurisdiction of its incorporation. Each Seller has full corporate power and authority to enter into and perform the Transaction Documents to which it is a party and to consummate the transactions contemplated thereby.

Schedule 5.2 hereto contains a complete and correct list setting out for each of the Transferred Companies the jurisdiction of incorporation, the registration details (name of register and registration number), the registered capital and the share ownership of each Transferred Company. The registered capital set out in Schedule 5.2 constitutes all of the authorized, issued and outstanding shares of capital stock of each Transferred Company, such shares of capital stock have been validly issued (as applicable) and are fully paid. There is with respect to each of the Transferred Companies no commitment providing for the issuance of any additional equity rights or providing for the issuance of securities convertible into shares of capital stock.

The sale and transfer of the Shares pursuant to Section 1.1 hereto is not subject to any consents or restrictions.

No insolvency or bankruptcy proceedings have been commenced or applied for in respect of the Transferred Companies. The Target Company is neither over-indebted (überschuldet) nor unable to pay its due debts (zahlungsunfähig), nor is illiquidity impending. With respect to the other Transferred Companies, no reasons exist which require or justify the opening, or applying for the opening, of insolvency or bankruptcy proceedings, in each case as determined under applicable Law of the relevant jurisdiction. Except as set out in Schedule 5.3 hereto, no Transferred Company is party to an enterprise agreement (Unternehmensvertrag) in the meaning of Sections 291 and 292 of the German Stock Corporation Act (AktG) or comparable profit sharing or pooling agreements or any such arrangements under the Laws of other jurisdictions, under which such Transferred Company is obliged to transfer its profits (or parts thereof) or to subordinate its management (or parts thereof) to any third party other than a Transferred Company.

of any of the Transaction Documents by any Seller nor the consummation by any Seller of the transactions contemplated thereby will (i) violate any of the terms of the articles of incorporation or by-laws (as applicable) of any Seller or any Transferred Company, or (ii) to the Sellers’ Knowledge, violate any applicable Law.

Prior to the Closing, the Sellers shall be entitled to supplement or amend any of the Schedules to Section 5 of this Agreement by written notification to the Buyers, however, only in accordance with the following terms:

(a)    The Sellers shall not be entitled to update Schedules with regard to (i) matters which

(b)    Schedules relating to litigation and any other Third Party Claims may be supplemented or amended, provided, however, that any single supplementation or amendment resulting in Losses (i) less than one million Euros (EUR 1,000,000) shall qualify, supplement and amend the Sellers’ Guarantees accordingly, and (ii) exceeding one million Euros (EUR 1,000,000) shall not be deemed to qualify, supplement or amend the Sellers’ Guarantees but be subject to indemnification by Sellers according to the provisions of this Agreement.

(c)    All other Schedules to Section 5 of this Agreement may be supplemented or amended, and the supplemented or amended Schedules shall qualify, supplement and amend the Sellers’ Guarantees accordingly.

(a)    Except as set forth in Schedule 7.2 or as otherwise provided in this Agreement (including as may be necessary to complete the Restructuring), from the date hereof until the Closing Date, Sellers will, and will cause each Transferred Company and the Asset Seller (with respect to the Business), to the extent permitted by applicable Laws, to carry on the Business in the ordinary course consistent with past practice. In particular, from the date hereof until the Closing Date, Sellers will not, and to the extent permitted by applicable Laws, will cause each Transferred Company and the Asset Seller (with respect to the Business) not to, take any of the following measures, unless such measures are (i) permitted or provided for under this Agreement, (ii) Restructuring Steps, or (iii) agreed by the Share Buyer in writing (including per e-mail); provided, however, that (x) the Share Buyer, if requested in writing (including per e-mail) shall not withhold its consent unreasonably, and (y) if the Share Buyer has not replied to a written (including per e-mail) request of any of the Sellers within five (5) Business Days, it shall be deemed that the Share Buyer has consented to the respective measure as required by this Section 7.2:

(xv)    making any capital expenditures in excess of an aggregate of one hundred thousand Euros (EUR 100,000);

(xvii)    making any non-cash distributions which do not result in a corresponding liability of a third party (including any members of the Sellers' Group), e.g. dividends in kind; or

(xviii)    execution of any agreement to carry out or resolve any of the foregoing.

(b)    To the extent permitted by applicable Laws, the Sellers shall further procure that, from the date hereof until the Closing Date, any of the Transferred Companies and the Asset Seller will fulfill any of their payment obligations (including, for the avoidance of doubt, Tax payments) when due and do not materially extend the payment terms (keine wesentliche Verlängerung der Zahlungsfristen) compared to past practice prior to the date hereof.

On or prior to the Closing, the Sellers shall, and shall cause each Transferred Company and Sellers’ Affiliates to, terminate the agreements with the Sellers and their Affiliates listed in Schedule 7.3 (the “Terminated Intragroup Agreements”). The Sellers hereby undertake to procure that the outstanding loan amounts (including any interest accrued thereon) under the loan agreement listed in Schedule 7.3, section 2, are fully repaid to the relevant Transferred Company or forgiven prior to the Closing Date.

The Sellers shall cause those directors and/or officers of the Transferred Companies whose primary employment is with a company other than a Transferred Company and designated by the Buyers in writing ten (10) Business Days prior to the Closing, to submit their written resignations from their positions, effective on the Closing Date. The Buyers shall cause each Transferred Company to appoint new directors and/or officers as may be required under applicable Laws.

From and after the Closing Date, the Sellers shall, whenever reasonably requested by Buyers, permit Buyers and each Transferred Company to have reasonable access for reasonable periods during normal business hours, as soon as feasible following receipt of a prior written notice (taking into account the urgency of the matter) to Sellers, to such books and records retained by the Sellers (including the right to make and retain copies thereof), to the extent the same relate to the Business and periods until the Closing Date, as is reasonably necessary for financial reporting, Tax matters, accounting matters and labor matters (including occupational illnesses or accidents) or the preparation of any filing or other submission required by applicable Law or for other purposes envisaged by this Agreement, including the conduct of defense of Direct Claims and Third Party Claims as set forth in Section 11. The Sellers shall maintain copies of all such books and records until the expiration of any applicable statutory period requiring the maintenance of such books and records (or for such longer period as may reasonably be requested by the Buyers in writing in light of ongoing litigation at the expiry of the applicable statutory period).

Each Seller shall use its reasonable efforts (except to the extent otherwise provided herein) to implement the provisions of this Agreement, and for such purpose each Seller, at the reasonable request of Buyers, at or after the Closing, shall, without further consideration, promptly execute and deliver or cause to be executed and delivered, to Buyers such deeds, assignments, bills of sale, consents and other instruments in addition to those required by this Agreement and the Related Agreements, and take all such other actions, as may be reasonably necessary or desirable, to implement any provision of this Agreement and the Related Agreements.

(a)    The Sellers’ Representative agrees not to engage, directly or through any of its Controlled Affiliates, as a proprietor, shareholder, or independent contractor in any Competing Business for a time period of three (3) years following the Closing Date. “Competing Business” shall mean the Ceiling Grid Business and/or the Compound Business in the Territory.

(b)    Notwithstanding anything of the foregoing, Sellers shall not be deemed to violate or be in default under the covenant in this Section 7.7 as a result of any investment in fifteen percent (15%) or less of the outstanding capital stock or other ownership interests in any Person.

(c)    This Section 7.7 shall not be construed to prohibit the acquisition by any of the Sellers or any of their Affiliates (each an “Acquiring Person”), in the context of any acquisition, merger, joint venture, asset purchase, or any other business combination (the “Acquisition”), of an ownership interest in a Person which derives less than twenty-five percent (25%) of its consolidated revenues in its most recent fiscal year from a Competing Business.

(d)    This Section 7.7 shall not be construed to prohibit the acquisition or ownership, for investment purposes only, by any employee savings, retirement, or similar benefit fund or plan of any of the Sellers or their Affiliates, of any ownership in any company engaged in a Competing Business; provided, however, that the investment decisions of such fund or plan shall be made by independent trustees or independent managers.

From and after the date hereof and for a period of one (1) year after the Closing Date, the Sellers’ Representative shall not, and shall procure that its Controlled Affiliates will not, pro-actively solicit or recruit any Transferred Employee or induce any Transferred Employee to terminate the employment or service relationship with any of the Buyers or any of their Affiliates (including any Transferred Company); provided, however, that the Sellers’ Representative or any of its Affiliates shall be allowed to employ any Transferred Employee (i) who approached the Sellers’ Group in response to a general employment advertisement by the Sellers’ Representative or any of its Affiliates; (ii) who was contacted by an independent recruiter in connection with employment by the Sellers’ Representative or any of its Affiliates; provided that neither the Sellers’ Representative or any of its Affiliates did specifically direct the recruiter to contact such Transferred Employee; (iii) who approached the Sellers’ Representative or any of its Affiliates without any prompting by the Sellers’ Representative or any of its Affiliates; or (iv) whose employment has been terminated by the Buyers or any of their Affiliates (including any Transferred Company), as the case may be.

(a)    The Sellers shall procure that, prior to the Closing Date, Sellers’ Group will complete the restructuring as set forth in Schedule 3.3(b) (the “Restructuring”). In particular, the Sellers shall procure that before the Closing Date, the Target Company (i) distributes the notes issued in steps 3a and 3b of Schedule 3.3(b) to the Share Seller in cancellation of the notes and (ii) either (x) distributes and pays out as dividends all Cash and Indebtedness Assets available for distribution within the limitations provided by the applicable Laws, provided that the German Tax Authorities have consented to the change of the fiscal year of the Target Company as planned as part of the Restructuring, or (y) if such consent was not granted, distributes and pays out as interim dividends (Vorabausschüttung) all Cash and Indebtedness Assets available for distribution within the limitations provided by the applicable Laws. The Buyers shall procure that, after the Closing Date, the Target Company will not assert any claims for reimbursement of any amounts distributed pursuant to subsection (y) of the preceding sentence (such amounts, the “Distributions”). In the event the Target Company or any other Person will assert any claims against any Seller for reimbursement of any Distributions, the Buyers hereby guarantee by way of an independent promise of guarantee (selbständiges Garantieversprechen) within the meaning of Section 311 of the BGB to reimburse the respective Seller the amount of the Distributions and any interest thereon claimed by the Target

Company or any Person, as the case may be.

(b)    The Sellers hereby undertake that the Restructuring will be implemented by the members of Sellers’ Group at their own cost, and any obligations and liability, including any Tax liabilities, resulting or arising from the Restructuring, shall be borne by the Sellers’ Group (excluding the Transferred Companies).

The Sellers hereby undertake to offer, and shall cause their Affiliates to offer, to sell the Required Materials (including the materials described in Schedule 5.22) to the extent not otherwise available for a period of five (5) years after the Closing Date to the Buyers, the Transferred Companies and other members of the Knauf Group for the use or distribution in the Territory at the same terms and conditions which apply to the Asset Seller and/or the Transferred Companies prior to the date hereof.

The Sellers hereby undertake that in their negotiations of the assignment agreement relating to the Leased Real Property they will use their best efforts to ensure that the terms and conditions of the existing lease are maintained in all material respects. The Asset Buyer will use reasonable efforts to meet reasonable requests from the lessor in the course of the negotiations of the assignment agreement, e.g. by procuring a parent guarantee for its obligations under the lease.

(a)    The Parties acknowledge and agree that the sale of the Transferred Assets constitutes a “relevant transfer” within the meaning of the Transfer of Undertakings (Protection of Employment) Regulations 2006 (TUPE) and that accordingly the contracts of employment of the employees of the Asset Seller who, immediately prior to the Closing Date, work wholly or mainly in the United Kingdom (the “Transferred UK Employees”) and any Collective Agreements applicable to them shall have effect on and following the Closing Date as if originally made by and between the Transferred UK Employees and the Asset Buyer.

(b)    The Parties agree that Sellers’ Group (excluding the Transferred Companies) shall remain liable for any payments due to Transferred Employees (i) pursuant to the Special 2012 European Transaction Incentive Plan, a copy of which has been delivered to the Buyers prior to signing this Agreement; (ii) arising from or in connection with the Retained Pension Plan; (iii) with regard to Transferred UK Employees, to the extent such payments become due in the ordinary course prior to Closing; (iv) listed in Schedule 8.1(b), if such payments relate to arrangements set forth in their employment agreements (e.g. stay or termination bonuses) and are triggered by any act or omission of the Sellers prior to or at Closing; and (v) subject to Section 8.1(c) below, to the extent the Transferred UK Employees do not transfer to Asset Buyer according to applicable Laws. The Sellers shall indemnify and hold harmless the Buyers or, at Buyers’ sole discretion, the Transferred Companies from any Loss which arises due to Transferred Employees claiming from the Buyers or any of the Transferred Companies instead of from the Sellers any payments pursuant to the preceding

sentence, including, without limitation, any associated social security contributions.

(c)    If and to the extent (i) a Transferred UK Employee objects to the transfer of his/her employment relationship pursuant to Section 8.1(a) and, therefore, remains with the Asset Seller in accordance with applicable Laws and (ii) the Asset Seller can demonstrate that such objection has been directly caused by any substantial change (actual or prospective) in working conditions to the material detriment of any such Transferred UK Employee, which was envisaged by the Asset Buyer prior to Closing, the Asset Seller shall have, after the Closing Date, no liability vis-à-vis such Transferred UK Employee, and the Asset Buyer shall indemnify and hold harmless the Asset Seller from and against any reasonable and customary Losses (e.g., reasonable and customary severance payments) directly related to and caused by such objecting Transferred UK Employee, except as explicitly provided otherwise in this Agreement, it being understood that the Asset Seller shall be obliged to take reasonable and customary steps to minimize any such Losses to the extent legally permissible, in particular, without limitation, to terminate the employment relationship of such objecting Transferred UK Employee as soon as possible.

(d)    After the Closing Date, Buyers shall comply in all material respects with all mandatory provisions of the relevant applicable Laws and Collective Agreements which relate to the provision of remuneration and benefits to the Transferred Employees.

(e)    Schedule 8.1(b) hereto sets forth a list of those Transferred Employees whom the Buyers undertake to continue to employ for a period of at least one (1) year after the Closing Date or, if the employment of any of these Transferred Employees is being terminated in any manner contemplated by the Change in Control Agreement with such Transferred Employee within one year from the Closing Date, the Buyers shall be liable for any Compensation under the respective Change in Control Agreement.

(a)    The Buyers hereby agree and acknowledge that they shall not acquire under this Agreement any right on or to the trademark or trade name “USG”, or the right to register or to use trademarks, names, domain names or logos including “USG” or names, domain names or logos of similar import (the “Retained Names”). Except to the extent specifically authorized by the Sellers, in particular, without limitation, under the License Agreements, the Buyers shall not, and shall cause the Transferred Companies and their Affiliates not to, use such Retained Names or any confusingly similar name as from the Closing Date; provided, however, that the Buyers and the Transferred Companies as well as any of Buyers’ Affiliates which will conduct any part of the Business after Closing shall have the right to use such Retained Names under the License Agreements on products, packaging, shipping materials, literature and marketing materials in connection with the Business if and to the extent such materials were in existence as of the Closing Date and in any event for a period not exceeding six (6) months following the Closing Date; provided that (x) such use of the Retained Names shall not be in a manner which could reasonably be expected to create a confusion as to the origin of the products and services supplied by the Transferred Companies, the Asset Buyer (with respect to the Transferred Assets) or any of Buyers’ Affiliates which will conduct any part of the Business after Closing under the Retained Names, and (y) the Buyers shall, and shall cause each Transferred Company as well as any of Buyers’ Affiliates which will conduct any part of the Business after Closing to, as promptly as practicable after the Closing Date, affix on any such packaging, shipping and marketing materials a label indicating the name of the Buyers or any Affiliate of the Buyers (which will obtain after Closing ownership in any of the Transferred Companies, the

Transferred Assets or any part of the Business).

(b)    The Share Buyer hereby further agrees and acknowledges that the Share Seller will, and will cause the Transferred Companies as applicable to, vote, effective as of and subject to the occurrence of Closing, the name change of the Transferred Companies in order to exclude any references to “USG” and to adopt the new name “Knauf” or any other name that Share Buyer shall notify in writing to the Share Seller no later than five (5) Business Days before Closing. As soon as practicable after the Closing Date, Share Buyer shall, and shall cause the Transferred Companies to, carry out all necessary formalities to effect such name change and to stop using the former name of the Transferred Companies in any way.

All formalities relating to the transfer of any Owned IP or Licensed IP shall be made by Buyers, and (save for any Tax on Sellers’ net profits, income or gains) all costs associated therewith shall be borne by Buyers; provided that Sellers shall reasonably cooperate to that effect and provide all corresponding information, documents and records in their possession as is reasonably requested by Buyers for that purpose.

Buyers shall use its reasonable efforts (except to the extent otherwise provided herein) to implement the provisions of this Agreement and of the Related Agreements, and for such purpose Buyers, at the reasonable request of the Sellers, at or after the Closing, shall, without further consideration, promptly execute and deliver or cause to be executed and delivered, to Sellers such deeds, assignments, bills of sale, consents and other instruments in addition to those required by this Agreement and the Related Agreements, and take all such other actions, as may be reasonably necessary or desirable, to implement any provision of this Agreement and the Related Agreements.

(a)    The Buyers shall, at their own expense, make full and accurate submissions, notifications and filings with all antitrust or competition authorities listed in Schedule 3.3(a) hereto (the “Required Antitrust Authorities”), without undue delay after the date of this Agreement, if not made before, and shall supply promptly any additional information and documentary material that may be requested by such Required Antitrust Authorities, with a view to obtaining the satisfaction of the Closing Condition set forth in Section 3.3(a) above as soon as practicable.

(b)    Any such submission, notification, filing and additional information and documentary material shall be made in a timely manner and in full compliance with the applicable legal requirements.

(c)    The Buyers and the Sellers shall use their reasonable best efforts to ensure the satisfaction of the condition set forth in Section 3.3(a) above. In this respect, the Buyers shall not be obliged to accept conditions, obligations or other requirements which would (i) involve the divestiture of any business or assets, or (ii) in the Buyers sole reasonable discretion, disrupt the financial and commercial fairness of the transactions contemplated hereby.

(d)    The Sellers agree to cooperate and to use their commercially reasonable efforts to and to cause their Affiliates (where applicable) to cooperate with the Buyers, upon their request, in

providing the Buyers and their advisors such information in their possession as is reasonably necessary for the Buyers to make the appropriate antitrust filings.

From and after the Closing Date, Buyers shall, and shall cause each Transferred Company and their Affiliates to, whenever reasonably requested by the Sellers, permit the Sellers to have reasonable access for reasonable periods during business hours, as soon as feasible following receipt of a written notice (taking into account the urgency of the matter) to the Buyers, to such books and records transferred to the Buyers pursuant to this Agreement or maintained by each Transferred Company, to the extent the same relate to the Business and exist as of the Closing Date, as is reasonably necessary for financial reporting, Tax matters, accounting matters and labor matters (including occupational illnesses or accidents) or the preparation of any filing or other submission required by applicable Law or for other purposes envisaged by this Agreement, including the conduct of defense of Direct Claims and Third Party Claims as set forth in Section 11. The Share Buyer shall cause each Transferred Company to maintain all such books and records until the expiration of any applicable statutory period requiring the maintenance of such books and records.

During the due diligence process of the Business, the management, employees or respective advisors of the Sellers have given the Buyers access to projections, estimates, management analyses, budgets, and forecasts as well as pro forma business plans. The Buyers acknowledge that such information relies on assumptions as to future events and market conditions that may not occur. The Buyers shall bear the responsibility for determining the relevance of the use of such information for their own analyses and shall not be entitled to rely upon or seek indemnification in connection with this information. Consequently, the Buyers acknowledge that none of the Sellers or any of their Affiliates, corporate representatives, employees, agents, or representatives makes any Sellers’ Guarantee or makes any warranty of any type, whether express or implied, regarding projections, estimates, forecasts or plans.

The Parties agree that neither the Sellers’ Representative nor the Buyers nor any of their respective Affiliates shall issue or cause publication of any press release or other announcement or public communication with respect to this Agreement or the transactions contemplated hereby without the consent of the respective other Party hereto, which consent shall not be unreasonably withheld or delayed; provided, however, that nothing herein shall prohibit any Party from issuing or causing publication of any press release, announcement or public communication to the extent that such Party reasonably deems such action to be required by Law; provided further, that such Party shall consult with the other Party concerning the timing and content of such press release, announcement or communication before the same is issued or published.

Each of the Parties hereto shall treat (and shall direct its employees, counsels, auditors and

representatives to treat) the contents of this Agreement as confidential and shall refrain from disclosing this Agreement in whole or part, to any Person without the consent of the respective other Party (which consent shall not be unreasonably withheld or delayed), except to the extent necessary for the enforcement hereof or as otherwise required by Law or by any Governmental Authority (in which case, to the extent practicable, the disclosing Party shall give prior notice to the respective other Party, and if requested by such other Party, the disclosing Party shall seek to obtain a protective order or similar protection); provided, however, that (x) the Buyers may disclose and provide copies of this Agreement or any other Transaction Document to their Controlling Persons, any potential acquirors (direct or indirect) of the Buyers or any members of the Knauf Group and to their respective professional advisors, and (y) the Sellers may disclose and provide copies of this Agreement or any other Transaction Document to their Controlling Persons and to its and their respective professional advisors, provided that such Persons shall have agreed to maintain the confidentiality of this Agreement and any other Transaction Document in accordance with the terms of this Section 9.2 or shall otherwise be legally obligated not to disclose and to keep the contents of this Agreement and any other Transaction Document confidential. Notwithstanding the above, it is understood and agreed between the Parties that the Sellers will disclose the contents of this Agreement as is determined by Sellers to be necessary to comply with the Sellers’ Representative’s reporting and filing obligations with the United States Securities and Exchange Commission. The Sellers’ Representative will notify the Buyers prior to such disclosure (without such disclosure being subject to Buyers' prior consent or prior consultation with Buyers). The Parties agree that by entering into this Agreement, any other (separate) confidentiality agreement entered into among the Parties prior to the date hereof shall hereby be superseded and replaced.

Each of the Sellers and each of the Buyers shall use their commercially reasonable efforts to cause each of the Closing Conditions to be satisfied as soon as possible after the date hereof. None of the Sellers or the Buyers shall take any action that would, or that could reasonably be expected to, result in any of the Closing Conditions not being satisfied.

Except (i) as provided in Sections 8.3 (Intellectual Property Registration) and 9.5 (Taxes), (ii) for any costs of notarization of this Agreement or any other contracts or documents contemplated hereby, which shall be borne by Buyer and (iii) as otherwise provided herein, Sellers and Buyers shall bear their respective own costs and expenses incurred for the consummation of the transactions contemplated hereby.

(a)    Transfer Taxes. Buyers shall pay and bear all real estate transfer Taxes, stamp duties or similar Taxes (the “Transfer Taxes”) due in connection with the sale and transfer of the Transferred Assets and/or the Shares to the Buyers (but not, for the avoidance of doubt, Sellers' Taxes on the capital gain or any other Tax on Sellers’ net income, profits or gains or de-grouping charges or similar charges). The Buyers and each Transferred Company (or any Affiliate of Asset Buyer, with respect to the Transferred Assets) shall make all mandatory filings in relation to the registration of the sale of the Transferred Shares and Transferred Assets with the competent tax offices or any other competent Governmental Authority within the applicable time period. If the Sellers are held liable for any Transfer Taxes by a Third Person, the Buyers shall procure that the relevant Transferred Company shall upon Sellers' written request provide to the Sellers a copy of the proof of the payment

of such Transfer Taxes.

(b)    Other Taxes. Where it is necessary for the purpose of this Agreement to apportion between the Share Seller and the Share Buyer any Tax liability of a Transferred Company, such liability shall be apportioned between the pre-Closing period and the post-Closing period. The Share Seller shall be responsible for any Tax related to the pre-Closing period which shall be calculated as if the last business and fiscal year (Geschäftsjahr und Wirtschaftsjahr) of the relevant Transferred Company starting prior to the Closing Date and the respective tax assessment period (Veranlagungs- und Erhebungszeitraum) cease at the end of the Closing Date. The Share Buyer shall be responsible for any Tax related to the post-Closing period. With respect to Taxes relating to the Transferred Assets, the Sellers shall assist the Asset Buyer as requested, at the Asset Buyer’s reasonable expense, in the preparation and timely filing of all Tax returns due from the Asset Buyer for the calendar year during which the Closing occurred. Any penalties or late payment interests that have been triggered by any event in the pre-Closing period shall solely be borne by the Sellers.

(c)    Value Added Tax.

(i)    All amounts payable under this Agreement are exclusive of VAT. Subject to Section 9.5(c)(ii) below, if any such payment constitutes the whole or any part of the consideration for a taxable supply (whether or not that supply is taxable pursuant to the exercise of an option or the making of any election), the payer shall, in addition to the amount so payable and subject to receipt of an appropriate VAT invoice, pay an amount equal to any VAT properly chargeable on that amount.

(ii)    The Asset Seller and the Asset Buyer consider that the sale of the Transferred Assets by the Asset Seller to the Asset Buyer with a view to the Asset Buyer carrying on the Business is one to which the provisions of Article 5 VAT Order applies such that it should fall to be treated as neither a supply of goods nor a supply of services for value added tax purposes and accordingly, the Asset Seller will not seek to charge any VAT in respect of the sale unless (i) the Asset Buyer is in breach of any of the covenants set forth in Section 6.6 (whether before, on, or after Closing) or (ii) HM Revenue & Customs notifies the Asset Seller in writing that it is required to do so. If HM Revenue & Customs serves such written notification then the Asset Buyer shall pay to the Asset Seller the amount of any VAT so chargeable but only after the Asset Seller has provided an appropriate VAT invoice to the Asset Buyer and copy of the written notification from HM Revenue & Customs.

(d)    UK Capital Allowances. The Asset Buyer hereby agrees that it will enter into such elections under section 198 of the UK Capital Allowances Act 2001 as the Asset Seller may request in relation to any or all of the Transferred Assets (whether on or after Closing) and that as between themselves, the Asset Seller and the Asset Buyer agree that so far as is permissible, any allowances due under Part 2 of the UK Capital Allowances Act in respect of any of the Transferred Assets shall be retained by the Asset Seller.

(e)    Tax Refunds. The Buyers shall – unless the amount has already excluded or reduced the indemnification pursuant to Section 11.7(a)(i) – reimburse to the Sellers the amount of (i) any Tax refunded by a Tax Authority in cash to a Transferred Company which was paid by a Transferred Company at any time prior to the Closing Date and (ii) any Tax refunded by a Tax Authority by way of set-off or deduction to a Transferred Company which was paid by a Transferred Company at any time prior to the Closing Date, in each case if attributable to a pre-Closing period.

Buyers acknowledge and agree that each Transferred Company, the Facilities and the Transferred Assets shall cease to be covered by the Insurance Policies effective at 11:59 p.m. (CET) on the Closing Date until when it shall be the Sellers' obligation to maintain the Insurance Policies consistent with past practice. The Buyers undertake to enter into or, as the case may be, accede to, or to cause their Affiliates to enter into or accede to, new or existing insurance policies to provide the Transferred Companies, the Facilities, and the Transferred Assets (as applicable) with replacement insurance coverage adequate for the conduct of the Business and consistent with past practice effective as from such time on the Closing Date.

This Agreement may only be terminated

(a)    by mutual written consent of the Parties hereto;

(b)    by the Share Buyer (on behalf of the Buyers) if any of the Buyers’ Conditions or the Mutual Condition provided in Section 3.3(b) (Completion of Restructuring) has not been met by December 31, 2012;

(c)    by the Share Seller (on behalf of the Sellers) if any of the Sellers’ Conditions has not been met by December 31, 2012 and has not been waived by the Sellers by such date;

(d)    by the Share Seller (on behalf of the Sellers) if the Mutual Condition provided in Section 3.3(b) (Completion of Restructuring) has not been met by March 31, 2013;

(e)    by each Party if the Mutual Condition provided in Section 3.3(a) (Governmental Approvals) has not been met by March 31, 2013; or

(f)    by each Party if any Governmental Authority has enacted, issued, promulgated, enforced or entered any Law, or refused to grant any required consent or approval, that has the effect of making the consummation of the transactions contemplated hereby illegal or that otherwise prohibits the consummation of such transactions;

provided, however, that if a Party seeking termination pursuant to this Section 10.1 is purportedly in breach in any material respect of any of its representations, warranties, covenants or agreements contained in this Agreement (including, for the avoidance of doubt, a Party having in bad faith (wider Treu und Glauben) prevented the fulfillment of a Closing Condition or the occurrence of the Closing), then, that Party may not terminate this Agreement pursuant to this Section 10.1.

If this Agreement is terminated and the transactions contemplated thereby are abandoned as described in this Section 10:

(a)    this Agreement shall become void and of no further force or effect, except for the

provisions of Sections 9.1 (Press Releases), 9.2 (Confidentiality, which obligation shall remain in force for a period of five (5) years after the termination of this Agreement) and 9.4 (Costs and Expenses) and this Section 10;

(b)    all confidential information provided by either Party to the respective other Party shall be returned to such disclosing Party or, upon the disclosing Party's written request, destroyed;

(c)    notwithstanding the foregoing, nothing in this Section 10.2 shall be deemed to release either Party from any liability for any breach by such Party of the terms and provisions of this Agreement; provided, however, that if the Closing shall not occur, the Sellers shall not be held liable in any manner whatsoever for any breach of the Sellers’ Guarantees.

From and after the Closing, the Buyers (the “Buyer Indemnifying Party”) shall indemnify, defend and hold any member of Sellers’ Group (but excluding the Transferred Companies) (each a “Seller Indemnified Party”) harmless from and against any and all Losses incurred by such Seller Indemnified Party resulting or arising from or related to, or incurred in connection with, in each case directly:

(a)    any failure of the Asset Buyer to assume, pay, perform and discharge the Assumed Liabilities; and/or

(b)    any breach of any Buyers’ Guarantee, covenant, obligation or agreement of the Buyers contained herein and not cured by the Buyers (to the extent capable of cure) within thirty (30) calendar days following the receipt by the Buyers of a written notice from Sellers requesting that such failure or breach be remedied.

(a)    Subject to the terms and conditions of this Agreement, from and after the Closing, the Sellers (the “Seller Indemnifying Party”) shall indemnify, defend and hold the Buyers and any of their Affiliates (including after the Closing the Transferred Companies) (each a “Buyer Indemnified Party”), harmless from and against any and all Losses incurred by such Buyer Indemnified Party resulting or arising from, related to, or incurred in connection with, in each case directly:

(i)    any failure of the Asset Seller to assume, pay, perform and discharge its respective Retained Liabilities; and/or

(ii)    the Restructuring; and/or

(iii)    any breach of any Sellers’ Guarantee, covenant, obligation or agreement of any Seller contained herein and not cured by the Sellers (to the extent capable of cure) within thirty (30) calendar days following the receipt by Sellers of a written notice from the Buyers requesting that such failure or breach be remedied.

(b)    The Seller Indemnifying Party shall in addition indemnify the Buyers, or at the Buyers’ election, any of their Affiliates, including after Closing the Transferred Companies or their legal successors, from and against:

(i)    all Taxes which have to be paid or discharged otherwise (including by way of set-off or deduction) by the Buyers, any of its Affiliates, including after Closing any of the Transferred Companies, or their legal successors arising from a breach of any of the Sellers’ Guarantees as described in Section 5.15;

(ii)    all Taxes which have to be paid or discharged otherwise (including by way of set-off or deduction) by any Transferred Company and are allocable to any period prior to and including the Closing Date (or portions thereof);

(iii)    all Taxes (including, but not limited to transfer Taxes, real estate transfer Tax, stamp duty, deed Tax and capital gains Taxes) which are triggered by any measures or actions taken in order to implement the Restructuring and which have to be paid or discharged otherwise (including by way of set-off or deduction) by the Buyers, any of its Affiliates, including after Closing, any of the Transferred Companies, or their legal successors; and

(iv)    all Taxes or amounts on account of Tax that the Buyers or any of their Affiliates (including after Closing the Transferred Companies) are or will be required to pay as a result of a failure by the Sellers or any of their Affiliates (other than, to the extent Closing occurs, the Transferred Companies) to discharge that Tax and/or any such Taxes or amounts properly attributable to the Sellers or any of their Affiliates (other than, to the extent Closing occurs, the Transferred Companies);

(the “Indemnifiable Taxes”), by paying an amount equal to such Indemnifiable Taxes to the Buyers, or at Buyers’ election, the Transferred Companies or their legal successors (the “Tax Indemnification Payment”).

Any indemnification under this Section 11 with respect to any claim concerning any Loss shall be payable upon (a) the resolution of such claim by mutual agreement between Sellers and Buyers; (b) the issuance of a definitive order from a Governmental Authority or a final judgment, award, order or other ruling (which is not subject to appeal or with respect to which the time for appeal has elapsed) by a court or arbitral tribunal having jurisdiction over this Agreement, the Parties and the subject matter of such claim or to which such claim was submitted for resolution by joint agreement between Sellers and Buyers; or (c) the final settlement of such claim with a Third Person in accordance with the provisions of this Agreement.

If any Buyer Indemnified Party or Seller Indemnified Party (hereinafter the “Indemnified Party”) (a) receives notice of the assertion of any claim, the commencement of any suit, action or proceeding (including without limitation any Tax audit, investigation or other measure of a Taxing Authority), or the imposition of any penalty or assessment by a third party in respect of which indemnity may be sought under Section 11.1 or Section 11.2 (a “Third Party Claim”); or (b) shall

have a claim for indemnification under Section 11.1 or Section 11.2 which does not relate to a Third Party Claim (a “Direct Claim”), such Indemnified Party shall provide written notice thereof to the Party from which indemnification is sought, i.e., the Seller Indemnifying Party or the Buyer Indemnifying Party, as the case may be, (the “Indemnifying Party”) in accordance with Section 13.8 (the “Notice”). The Notice shall provide a description in reasonable detail of the nature of the Direct Claim or Third Party Claim, the sections of this Agreement which form the basis for the indemnification claim, copies of all material evidence in connection therewith (including court papers) and the estimated amount of Loss suffered or incurred by the Indemnified Party (to the extent such amount is known or can be determined). Such Notice shall be made within twenty (20) Business Days following the date of receipt by the Indemnified Party of any Third Party Claim or from the date on which the Indemnified Party had knowledge of any Direct Claim; provided, however, that such twenty (20) Business Days period shall be reduced if the urgency of the matter dictates a swifter notification to the Indemnifying Party. To the extent the Indemnifying Party can demonstrate and prove that any failure of the Indemnified Party to provide Notice to the Indemnifying Party in accordance with this Section 11.4.1 has caused an increase of a Loss, any indemnification obligation by the Indemnifying Party under this Section 11 shall be reduced accordingly.

(a)    The Indemnifying Party shall have the right, by giving written notice to the Indemnified Party, at its option, to participate in, or to elect to assume, the defense of any Third Party Claim, at the Indemnifying Party’s own expense and by its own counsel, provided, however, that with regard to Third Party Claims relating to Taxes, the Indemnifying Party shall only have the right to assume the defense of any Third Party Claim if the Third Party Claim relates exclusively to Taxes attributable to any time period prior to and including the Closing Date. If the Indemnifying Party undertakes to assume the defense of any Third Party Claim, it shall promptly notify the Indemnified Party of its intention to do so, and the Indemnifying Party shall not be liable for any expenses subsequently incurred by the Indemnified Party in connection with the defense thereof. The Indemnified Party shall cooperate with, and provide appropriate documentation as reasonably requested by, the Indemnifying Party and its counsel in the compromise of, or defense against, any such Third Party Claim. In any event, the Indemnified Party shall have the right, at its own expense, to participate in the defense of any Third Party Claim as to which the Indemnifying Party has assumed the defense. The Indemnifying Party shall not admit any liability with respect to, or settle, compromise or discharge, any such Third Party Claim without the prior consent of the Indemnified Party, unless the proposed resolution involves only the payment of money damages by the Indemnifying Party and the Indemnified Party cannot be held liable for such payment.

(b)    In the event that the Indemnifying Party does not elect or does not have the right to assume the defense of a Third Party Claim in accordance with paragraph (a) of this Section 11.4.2, the Indemnified Party shall control the defense of such Third Party Claim with counsel of its choice; provided, however, that the Indemnified Party shall not settle or compromise any Third Party Claim without the Indemnifying Party’s prior written consent, which consent shall not be unreasonably delayed or withheld. The Indemnifying Party shall be entitled (at the Indemnifying Party’s expense) to participate in the defense of any Third Party Claim with its own counsel, in which case, the Indemnified Party shall provide all relevant information to the Indemnifying Party.

(c)    Whether or not the Indemnifying Party shall have assumed the defense of any Third Party Claim, the Indemnified Party shall not admit any liability with respect to, or settle, compromise or discharge, any such Third Party Claim without the Indemnifying Party's prior consent, which

consent shall not be unreasonably delayed or withheld.

(d)    Buyers shall promptly notify Sellers of any announced and ongoing Tax audits of any time period prior to the Closing Date and of any other administrative or court proceedings which could trigger any liability of Sellers under this Agreement that relates to Taxes and inform the Sellers as regards the subject matter of the respective Tax audit. Buyers shall ensure that copies of all the relevant correspondence with Governmental Authorities relating to and during the Tax audit is being provided promptly to Sellers. Tax audits shall be treated as Third Party Claims and be subject to the provisions of this Section 11.4.2.

(a)    The right of any Buyer Indemnified Party to claim indemnification under Section 11.2 shall expire as follows:

(i)    any claims for indemnification relating to any breach of any of the Sellers’ Guarantees set forth in Section 5.11 (Environmental Matters) and any Environmental Indemnification Claims pursuant to Section 12 (Environmental Indemnification) shall expire on the fifth (5^th) anniversary of the Closing Date;

(ii)    any claims for indemnification relating to any breach of any of the Sellers’ Guarantees set forth in Section 5.15 (Tax Matters) and any other claim for indemnification with regard to Taxes shall become time-barred upon expiration of three (3) months after the final and binding (formell und materiell bestandskräftig) assessment, agreement or determination (as applicable) of the relevant Tax liability;

(iii)    any claims for indemnification relating to any breach of any of the Sellers’ Guarantees set forth in Sections 5.1, 5.2, 5.6(a) and 5.6(b) shall not be limited in time; and

(iv)    any other claims of any Buyer Indemnified Party for indemnification under this Agreement shall expire twenty-four (24) months after the Closing Date.

(b)    The right of any Seller Indemnified Party to claim indemnification under this Agreement shall expire twenty-four (24) months after the Closing Date.

(a)    With regard to the indemnification obligations of Seller Indemnifying Party under this Agreement the following shall apply:

(i)    any indemnification obligations (x) for any breach of the Sellers’ Guarantees under Section 5.1, 5.2, 5.3, 5.6(a) and 5.6(b) and (y) for any claims relating to Taxes under this Agreement shall not be capped (together, the “Uncapped Indemnity”);

(ii)    save for the Uncapped Indemnity, until the second (2^nd) anniversary following the Closing Date (the “First Indemnification Period”), the Buyers shall be entitled to claim indemnification hereunder up to a maximum amount of fifteen million U.S.-Dollars (USD 15,000,000) (the “Main Liability Cap”);

(iii)    save for the Uncapped Indemnity, in the time period beginning on the first

(1^st) day after the second (2^nd) anniversary of the Closing Date and ending on the fifth (5^th) anniversary of the Closing Date (the “Second Indemnification Period”), the Buyers shall be entitled to claim indemnification for breaches of the Sellers’ Guarantees set forth in Section 5.11 (Environmental Matters) and pursuant to Section 12 (Environmental Indemnification) up to a maximum amount of seven million U.S.-Dollars (USD 7,000,000) (the “Environmental Cap”); provided, however, that any amounts paid by a Seller Indemnifying Party with respect to claims made by Buyers Indemnified Party during the First Indemnification Period for breaches of the Sellers’ Guarantees set forth in Section 5.11 (Environmental Matters) and/or pursuant to Section 12 (Environmental Indemnification), shall reduce the Environmental Cap; and

(iv)    save for the Uncapped Indemnity, the total amount of indemnification to be paid by the Sellers under this Agreement shall in no event exceed an amount of twenty million U.S.-Dollars (USD 20,000,000) (the “Aggregate Maximum Liability”).

(b)    Except for claims under the Uncapped Indemnity, the Buyer Indemnified Party shall not be entitled to make any claim for indemnification under this Agreement unless and until the aggregate amount of claims for Losses of Buyer Indemnified Party exceeds an amount of nine hundred thousand U.S.-Dollars (USD 900,000) (the “Threshold Amount”). If the Threshold Amount is exceeded, the Seller Indemnifying Party shall be liable for the full amount of Losses (Freigrenze).

(c)    Except for claims under the Uncapped Indemnity, no claim of Buyer Indemnified Party in respect of any individual event or occurrence shall be deemed to give rise to indemnification under this Agreement, or shall be taken into account for purposes of calculating the Threshold Amount, unless and until the Loss related to such claim exceeds an amount of eighty thousand U.S.-Dollars (USD 80,000) (the “De-Minimis Amount”). The Parties agree that a De-Minimis Amount of ten thousand U.S.-Dollars (USD 10,000) shall apply to claims relating to Taxes. For the purposes of this Section 11.6(c), in the event of a series of claims based on the same or a related set of facts, events or circumstances, such series of claims shall be treated as a single claim and the aggregate total of the Losses resulting from such series of claims shall be used to determine whether the De-Minimis Amount has been exceeded.

(d)    The Sellers shall not be responsible and liable for Indemnifiable Taxes if and to the extent the relevant Indemnifiable Tax has been paid or discharged otherwise (including by way of set-off or deduction) prior to or on the Closing Date.

(e)    Reasonable costs and expenses incurred by the Sellers and their Affiliates for any remediation in kind as contemplated by Section 12.4 for which Sellers can present bills and receipts or other reasonable evidence, including reasonable costs for the use of own personnel and equipment, shall count against the Main Liability Cap and the Environmental Cap, as applicable.

(a)    The amount of any indemnity payable hereunder on account of a Loss (including, without limitation, of a Loss arising from a breach of a warranty or representation contained in this Agreement) shall be:

(i)    reduced by the net present value of any present or future net Tax benefit or Tax saving (including without limitation and where applicable a Tax deduction or loss, basis adjustment and/or shifting of income, deductions, gains, loss and/or credits, excluding, however, the increase of any mere loss carry forward) arising as a result of the matter giving rise to the Loss

to the extent such benefit or saving is realized and gives rise to an actual saving of Tax by the Indemnified Party, unless the respective Tax benefit or Tax saving has already been refunded as a Tax refund pursuant to Section 9.5(e); and

(ii)    increased by any Tax actually incurred by the Indemnified Party as a result of or related to the indemnification payment (including without limitation any Tax related to the inclusion, if required by Law, in gross income of insurance proceeds or a payment pursuant hereto, and including any Tax indirectly suffered by the Indemnified Party by reason of a deduction or withholding on account of Tax from a payment pursuant hereto).

The net present value of any relevant present or future net Tax benefit or Tax saving shall be determined on the basis of a Tax rate of thirty per cent (30%) and an applied discount factor of three per cent (3%) p.a.

(b)    The amount of any indemnity payable hereunder on account of a Loss shall be calculated net of any amounts recovered from Third Persons, including subsidies and amounts recovered under insurance policies with respect to such Loss (less any reasonable costs of recovering such amounts). Any Indemnified Party suffering any Loss giving rise to indemnification under this Section 11 shall make commercially reasonable efforts (whereby each Party may decide at its sole discretion whether to sue a Third Person) to recover such Loss from Third Persons, including insurance companies, so as to reduce the amount of any indemnification hereunder. If an Indemnified Party receives proceeds from Third Persons, including insurance proceeds, in connection with Losses for which it has received indemnification hereunder, such Indemnified Party shall promptly refund to the Indemnifying Party the amount of such proceeds when received (less any reasonable costs of recovering such amounts), up to the amount of indemnification received hereunder.

Any Indemnified Party shall take all reasonable steps to mitigate in accordance with Section 254 of the BGB any Loss that it may incur.

(a)    Seller Indemnifying Party shall have no obligation for indemnification pursuant to Section 11.2 hereof for any Loss resulting from a breach of any of the Sellers’ Guarantees the basis of which is actually disclosed (i) in a narrative, in form of a clear reference to a specific contract or other document or in a list in the schedules attached to this Agreement (the “Schedules”) and as such may be amended or supplemented before Closing by Sellers in accordance with Section 7.1 (provided, however, that any information disclosed in any section of the Schedules shall be deemed to be disclosed with respect to such other Sections of this Agreement or the Schedules to which such disclosure on its face would reasonably pertain in light of the form and substance of the disclosure made); or (ii) in the Disclosed Information; provided, however, that any of the Sellers’ Guarantees set forth in Section 5.11 (Environmental Matters) and Section 5.15 (Tax Matters) as well as, for the avoidance of doubt, indemnification claims relating to Taxes or based on Section 12 (Environmental Indemnification) shall in no event be excluded or limited in any way by disclosure of facts or circumstances hereunder, in the Schedules or in the Disclosed Information.

(b)    Save in relation to the Taxes and amounts in respect of Tax specified in Section 11.2(b)(i) to 11.2(b)(iv), Seller Indemnifying Party shall have no obligation for indemnification pursuant to Section 11.2 hereof for any Loss resulting from a change in any applicable Laws after the Closing

Date or from an implementation of any Law becoming effective after the Closing Date.

(c)    In no event shall any Indemnified Party be entitled to double recovery hereunder. In particular, in the event any circumstances constitute a breach of more than one representation and warranty, obligation or covenant on the part of the Indemnifying Party, the Indemnified Parties shall only be entitled to be indemnified once in respect of such circumstances.

(d)    In no event shall any Indemnified Party be entitled to indemnification under this Section 11 in respect of a Loss, the legal basis of which has already been specifically taken into account in the adjustment of the Purchase Price pursuant to Section 2.2, including in the determination of the Final Working Capital or the Final Indebtedness.

(e)    For the avoidance of doubt, the indemnification obligation of Sellers under this Section 11 shall be limited to the Loss (giving effect to the limitations set forth in this Section 11) actually suffered by the Buyer Indemnified Party (and/or, in relation to the matters specified in Sections 11.2(b)(i) through 11.2(b)(iv), its Affiliates), and shall be computed without regard to any cash flow or earnings multiple or similar valuation formula implicit in negotiating and/or setting the Unadjusted Purchase Price.

The rights under this Agreement are, apart from claims for specific performance (Erfüllungsansprüche), the sole and exclusive rights and remedies of the Buyers and the Sellers, as the case may be, with respect to this Agreement. Other than explicitly provided herein, any other claims or remedies, including the right to withdraw (zurücktreten) from this Agreement or to require the winding up (Rückabwicklung) or the alteration (Anpassung) of the transactions contemplated hereunder (e.g. by way of Störung oder Wegfall der Geschäftsgrundlage), any claims for breach of pre-contractual obligations (culpa in contrahendo) or ancillary obligations (positive Forderungsverletzung) or damages (Schadensersatz) other than expressly provided under this Agreement, except claims for willful deceit (arglistige Täuschung) and damages based on intent (Vorsatz), are hereby expressly excluded and waived by the Buyers and the Sellers to the extent legally permissible.

Any indemnity payment by any Seller Indemnifying Party to Buyer Indemnified Party under this Section 11 shall constitute damages and not a reduction in purchase price. Such payment shall be made to the party (as between the Buyers or each Transferred Company) which the Buyers shall have advised Sellers suffered the Loss.

(a)    “Environmental Damage” means any pollution by, existence of or emanation of Hazardous Material, ammunition, pollutants, structures, contaminants or wastes, which might cause hazards to the environment, life or health, of, in, from or through the air, the soil gas, the soil, the groundwater, the surface water, leachate, or structures (i) of any land, properties, buildings, structures

or real estate currently or formerly owned, possessed or operated by the Target Company or any of the Transferred Companies, or any of their legal predecessors if and to the extent the Target Company or any of the Transferred Companies is liable under Environmental Laws in lieu of such legal predecessor, (ii) of the premises (including any properties, buildings, structures) in Peterlee, Durham, United Kingdom, currently operated by the Asset Seller, or (iii) being caused by the Target Company, any of the Transferred Companies or the Asset Seller, or any of their respective legal predecessors, if and to the extent the Target Company, any of the Transferred Companies, the Asset Buyer or any of their legal successors, respectively, is liable under Environmental Laws in lieu of such legal predecessor or in lieu of the Asset Seller.

(b)    “Environmental Law” means any applicable laws, statutes, ordinances, European directives and regulations, judgments, administrative provisions, administrative orders, licenses or permits, agreements with Governmental Authorities, land-use planning or zoning regulations or other governmental regulations as in effect and applicable in the relevant jurisdictions on the Closing Date imposing liability, or standards of conduct, for the protection of or the prevention of harmful effects to the environment, in particular human beings, and plants and the health and safety of the work place, or the use, handling, generation, treatment or release of Hazardous Material.

(c)    “Hazardous Material” means dangerous substances as defined in Article 3 Regulation (EC) No 1272/2008 of the European Parliament and of the Council of 16 December 2008, as in effect as of the Closing Date, or any substances that are as of the Closing Date legally defined as hazardous under any applicable Environmental Law.

(a)    The Sellers shall indemnify and hold harmless the Buyer Indemnified Parties from any Losses actually incurred or suffered by any of the Buyer Indemnified Parties after the Closing Date which arise out of or relate to any Environmental Damage existing on or before the Closing Date and incurred or suffered based on (i) a final and binding (rechtskräftig) and enforceable (vollziehbare) court decision, (ii) a final and binding (bestandskräftig) or immediately enforceable (sofort vollziehbar) order issued by a competent Governmental Authority, (iii) a requirement under applicable Environmental Laws, if the non-compliance with such Environmental Laws involves criminal liability of any manager or employee of the Knauf Group (including after Closing the Transferred Companies) and, in particular, except such requirements that are being customarily ignored in the respective geographic area by other persons, (iv) a written claim relating to any Environmental Damage of a Third Person addressed to any Buyer Indemnified Party, (v) an immediate endangerment for the environment, health or life (unmittelbare Gefahr für Umwelt, Leib oder Leben), (vi) any measures undertaken by any Buyer Indemnified Party having been agreed to by the Sellers in a form provided in Section 13.8 for notices, or (vii) any obligation of any Buyer Indemnified Party relating to any Environmental Damage existing on or before the Closing Date which is due for fulfillment under an administrative contract or a private law agreement entered into by (A) any of the Sellers, the Target Company, a Transferred Company or the Asset Seller prior to the Closing Date or (B) by any Buyer Indemnified Party after the Closing Date; provided that the Sellers have given their prior written consent (which cannot be unreasonably withheld) (each claim under this Section 12.2 an “Environmental Indemnification Claim”).

(b)    At the Sellers’ request, any Buyer Indemnified Party shall provide to the Sellers and their experts and advisers reasonable access to the affected site, facilities, installations and buildings during ordinary business hours and after reasonable notification in advance, to the extent this is

necessary to validate the Environmental Indemnification Claim.

(a)    The Sellers’ obligation to indemnify and hold harmless any Buyer Indemnified Party pursuant to this Section 12 shall be excluded if and to the extent that:

(i)    the respective obligation, claim, liability, cost or expense (including reasonable attorney’s fees) could have been avoided or mitigated by any Buyer Indemnified Party within the meaning of Sec. 254 BGB; or

(ii)    the Loss relating to an Environmental Damage has been recovered from a Third Person or any insurance.

(b)    The Buyers shall not be entitled to indemnification for Losses resulting from Environmental Damages if and to the extent the respective Environmental Damage has been remediated by the Sellers in accordance with applicable Environmental Laws and Section 12.4 below. If the Buyers have not observed their obligations under Section 12.4, the Sellers shall not be liable for Losses, if and to the extent the Share Buyer cannot demonstrate and prove to the Sellers that such breach of the Buyers’ obligations under Section 12.4 has not increased the costs for investigating, cleaning up or otherwise remediating the Environmental Damage that is claimed as a Loss.

(c)    For any indemnity claim asserted by the Buyers for Losses in accordance with this Section 12 or for a breach of any of the Sellers’ Guarantees set forth in Section 5.11 (Environmental Matters), the term “Losses” shall not include Losses to the extent such Losses are incurred by, or the underlying investigations, cleanup obligations or cleanup activities or other events triggering such Losses are the result of, a Buyer Indemnified Party (or any Person acting on its behalf) conducting after the Closing Date any of the following:

(i)    any expansion or change of use of the respective Real Property after the Closing Date; or

(ii)    any construction activities on the respective Real Property after the Closing Date; or

(iii)    any notification of or information to any Governmental Authority (other than if imposed by applicable Laws); or

(iv)    any other drilling, soil or groundwater examination or other investigation of any Real Property, other than for a valid business reason, whereas the Parties acknowledge and agree that any such activity the purpose of which is to create an opportunity to make a claim for indemnification under this Agreement, or any other activity that cannot reasonably be justified absent Sellers’ obligations under this Agreement hereof will not be deemed to have a valid business reason.

(a)    In the event any Buyer Indemnified Party has any claim for indemnification against the Sellers in accordance with this Section 12 or for a breach of any of the Sellers’ Guarantees set

forth in Section 5.11 (Environmental Matters), the Buyers shall provide to the Sellers a Notice as set forth in Section 11.4.1, provided, however, that such Notice shall be made within fifty (50) Business Days following the date on which the Buyer Indemnified Party obtains knowledge of any Environmental Indemnification Claim. The Sellers shall have the right, at their sole discretion, to decide by delivery of a written declaration to the Buyers, within a period of fifty (50) Business Days after receipt by the Sellers of the respective Notice, to remediate in kind the damage that is the subject matter of a Notice relating to the Environmental Damage. The fifty (50) Business Days period pursuant to the preceding sentence shall not apply if any activity is necessary without undue delay (unverzüglich) for legal or factual reasons, in which case (A) the Buyers shall have the obligation to notify the Sellers without undue delay, and (B) the Sellers shall have the obligation to decide on and perform the remediation of the Environmental Damage in a reasonable shorter period of time.

(b)    If within the fifty (50) Business Days period pursuant to Section 12.4(a) above the Sellers have not notified the Buyers or have decided against a remediation in kind, the Buyers shall be entitled to indemnification as set out in Section 12.2 for any Environmental Damages. If the Sellers decide to remediate any Environmental Damages, they shall consult the Buyers in advance as regards any remediation measures and reasonably cooperate with the Buyers. The Buyers shall not unreasonably withhold any consent in connection with remediation activities of the Sellers and cooperate in good faith as necessary to enable the Sellers to remediate in kind any Environmental Damages.

Section 11.3 and Section 11.4 shall apply to this Section 12 mutatis mutandis.

With regard to the limitation period for any Environmental Indemnification Claim hereunder, Section 11.5(a)(i) shall apply. Limitations for Environmental Indemnification Claims hereunder are set out in Sections 11.6(a)(ii) through (iv), 11.6(b) and 11.6(c).

Each of the Sellers hereby irrevocably appoints USG Corporation as its representative (the “Sellers’ Representative”), with full power and authority to, in its name, place and stead, take all actions permitted or required to be taken by it pursuant to this Agreement, including:

This Agreement and the Schedules and Exhibits hereto, the Related Agreements and any other agreements expressly provided for herein set forth the entire understanding of the Parties hereto with respect to the subject matter hereof, and supersede all prior contracts, agreements, arrangements, communications, discussions, representations and warranties, whether oral or written, between the Parties.

This Agreement shall be governed by and enforced in accordance with German laws, excluding any choice of law rules that may direct the application of the laws of another jurisdiction and excluding the United Convention on Contracts for the International Sale of Goods (CISG).

(a)    Except for the expert proceeding provided for in Section 2.2.2 above, the Parties will, upon written request of either Party, endeavor to resolve any disputes, controversies or claims arising out of this Agreement, or the breach, termination or invalidity hereof (each a “Dispute”) by good faith negotiation between chief executive officers of the Parties (or such other representatives to which the Parties may agree having the authority to fully and finally resolve the Dispute) within a period of thirty (30) calendar days after one of the Parties has received a written notice of the Dispute from the respective other Party requesting good faith negotiations between the Parties. The Parties agree that no arbitration demand will be filed for such thirty (30) calendar days period. If requested by one or the other Party, the negotiations shall be assisted by an independent mediator jointly selected and paid for by the Parties.
