1.5 Closing Working Capital Adjustment.

(a) At least five (5) Business Days prior to the Closing Date, Parent shall prepare and deliver to Buyer, or shall cause to be prepared and delivered to Buyer, a statement (the “Estimated Closing Statement”) setting forth its good faith estimate of Closing Working Capital, Retained Cash Balances, Capex Shortfall, and Transferred Company Indebtedness, determined in accordance with the definitions of Closing Working Capital, Retained Cash Balances, Capex Shortfall, Transferred Company Indebtedness and, except as set forth on Schedule 2.4(a) of the Disclosure Letter, GAAP applied on a basis consistent with the application of such principles in the preparation of the Balance Sheet; provided that the Retained Cash Balances and Transferred Company Indebtedness included in the Estimated Closing Statement shall not include any Retained Cash Balances or Transferred Company Indebtedness arising under any Enterprise Agreements, which amount, if any, shall be included in the final determination of the Retained Cash Balances and Transferred Company Indebtedness.

(b) The Purchase Price payable on the Closing Date shall be calculated in accordance with Section 1.2 as if Parent’s estimate of Closing Working Capital, Retained Cash Balances and Transferred Company Indebtedness set forth in the Estimated Closing Statement was the actual amount of Closing Working Capital, Retained Cash Balances and Transferred Company Indebtedness. The Purchase Price as so estimated is referred to as the

“Estimated Purchase Price.” The Estimated Closing Statement shall be accompanied by a certificate executed by a senior financial officer of Parent to the effect that the Estimated Closing Statement has been prepared in good faith in accordance with this Section 1.5.

(c) On or prior to the date that is ninety (90) days following the Closing Date, Buyer shall prepare and deliver to Parent a statement (the “Final Closing Statement”) setting forth in reasonable detail its calculation of Closing Working Capital, Retained Cash Balances and Transferred Company Indebtedness, determined in accordance with the definitions of Closing Working Capital, Retained Cash Balances and Transferred Company Indebtedness, and GAAP applied on a basis consistent with the application of such principles in the preparation of the Balance Sheet. The Final Closing Statement shall be accompanied by a certificate executed by a senior financial officer of Buyer to the effect that the Final Closing Statement has been prepared in good faith in accordance with this Section 1.5(c). The Final Closing Statement shall also set forth, and explain, in reasonable detail, any differences between Buyer’s calculation of Closing Working Capital, Retained Cash Balances and Transferred Company Indebtedness from Parent’s estimate of Closing Working Capital, Retained Cash Balances and Transferred Company Indebtedness set forth in the Estimated Closing Statement.

(d) Buyer shall make available to Parent all workpapers and other books and records utilized by Buyer in the preparation of the Final Closing Statement, and shall make available to Parent those employees and representatives involved in the preparation of the Final Closing Statement. If Buyer employs a firm of independent accountants in connection with the preparation of the Final Closing Statement, subject to the execution by Parent of a customary non-reliance letter, Buyer shall cause such independent accountants to deliver to Parent and its representatives any computations and workpapers used in the preparation of the Final Closing Statement. Parent shall notify Buyer in writing within forty-five (45) days after Parent’s receipt of the Final Closing Statement that it accepts the Final Closing Statement or that there is a dispute (a “Dispute Notice”) as to any item reflected thereon (the “Disputed Items”). The Dispute Notice shall set forth, and explain, Parent’s objections, if any, to the Final Closing Statement in reasonable detail and Parent’s calculation of Closing Working Capital, Retained Cash Balances and Transferred Company Indebtedness. If Parent timely delivers to Buyer a Dispute Notice, only the Disputed Items shall be deemed to be in dispute, and all other matters included in the Final Closing Statement delivered by Buyer shall be deemed to be final and binding on the parties hereto. The failure by Parent to deliver to Buyer the Dispute Notice within such period shall be deemed to constitute Parent’s acceptance of the Final Closing Statement. After delivery of the Dispute Notice by Parent, the parties will use all reasonable efforts to resolve any Disputed Items, and any resolution by Parent and Buyer of such Disputed Items shall be final and binding on the parties hereto.

(e) If any Disputed Items cannot be resolved by the parties within forty-five (45) days after Parent delivers the Dispute Notice to Buyer, such Disputed Items shall be referred to BDO USA, LLP (the “Selected Accountant”). The determination of the Selected Accountant shall be conclusive and binding on each party. The fees and expenses of the Selected Accountant shall initially be shared equally by Parent and Buyer; provided, that such fees shall ultimately be allocated in accordance with Section 1.5(h). Not later than thirty (30) days after the referral of any Disputed Items to the Selected Accountant, Parent and Buyer shall

simultaneously submit written statements to the Selected Accountant (with a copy to the other party) setting forth their respective positions regarding the Disputed Items which remain in dispute. Parent and Buyer shall instruct the Selected Accountant to render its decision resolving the dispute within 30 days after submission of the written statements, and during such period, the parties shall make available to the Selected Accountant such employees, information, books and records as may be reasonably requested by the Selected Accountant to make its final determination. In resolving any Disputed Item, the Selected Accountant (i) shall be bound by the provisions of this Section 1.5 and the definitions of the Closing Working Capital, Retained Cash Balances and Transferred Company Indebtedness, (ii) shall limit its review to the Disputed Items submitted to the Selected Accountant for resolution, and shall be instructed not to otherwise investigate matters independently and (iii) shall further limit its review of the Disputed Items solely to whether the Final Closing Statement has been prepared in accordance with this Section 1.5 or contains any mathematical or clerical error. The determination of any Disputed Items cannot, however, be in excess of, or less than, the greatest or lowest value, respectively, claimed for any such item in the Final Closing Statement or the Dispute Notice. Parent and Buyer agree that the resolution by the Selected Accountant of any Disputed Items shall be final and binding on the parties hereto. Parent and Buyer agree that the procedure set forth in this Section 1.5 for resolving disputes with respect to Closing Working Capital, Retained Cash Balances and Transferred Company Indebtedness shall be the sole and exclusive method for resolving such disputes, provided that the parties hereto agree that judgment may be entered upon the determination of the Selected Accountant in any court having jurisdiction over the party against which such determination is to be enforced.

(f) If the Purchase Price as finally determined pursuant to this Section 1.5 (f) is less than the Estimated Purchase Price, Parent shall pay to Buyer an amount equal to the shortfall, or (ii) is more than the Estimated Purchase Price, Buyer shall pay to Parent an amount equal to the excess. Any such payment pursuant to the preceding sentence will be made by wire transfer of immediately available funds, to an account (or accounts) designated by Buyer or Parent, as the case may be, on the later of (x) the second (2nd) Business Day after acceptance or deemed acceptance by Parent of the Final Closing Statement (as contemplated by paragraph (d) above) or (y) the second (2nd) Business Day following resolution (as contemplated by paragraphs (d) or (e) above) of any Disputed Items; provided, however, that if the parties are disputing the final calculation of the Purchase Price, to the extent part of any payment that would be payable pursuant to this paragraph (f) is not in dispute, the payor shall pay the amount not in dispute on the date the payment would otherwise be due but for such dispute by wire transfer of immediately available funds to an account (or accounts) designated by the recipient. All payments made pursuant to this paragraph (f) shall be accompanied by interest at a rate equal to the Prime Rate per annum from the Closing Date through (but excluding) the date such payment is made. “Prime Rate” shall mean, for any day, the rate of interest per annum (over a year of 360 days) announced by JPMorgan Chase Bank, N.A. (or any successor thereto) from time to time, as its “base rate” in effect on such date. Any amounts payable by either party pursuant to this paragraph (f) may not be reduced by set-off against any amount(s) payable (whether at such time or in the future or upon the occurrence of a contingency) by the recipient or any Affiliate of the recipient to the payor or any Affiliates of the payor. Any payment required pursuant to this paragraph (f) shall constitute a payment in respect of the Purchase Price.

(g) If the delivery deadline date for the Final Closing Statement or the Dispute Notice is a day that is not a Business Day, the applicable delivery deadline date shall be the immediately following Business Day.

(h) In the event Parent and Buyer refer any Disputed Items to the Selected Accountant for resolution as provided in this Section 1.5, the responsibility for the fees and expenses of the Selected Accountant shall be as follows:

(i) if the Selected Accountant resolves all such Disputed Items in favor of Buyer’s position (the Purchase Price so determined is referred to herein as the “Low Value”), then Parent shall be responsible for all of the fees and expenses of the Selected Accountant;

(ii) if the Selected Accountant resolves all such Disputed Items in favor of Parent’s position (the Purchase Price so determined is referred to herein as the “High Value”), then Buyer shall be responsible for all of the fees and expenses of the Selected Accountant; and

(iii) if the Selected Accountant neither resolves all such Disputed Items in favor of Buyer’s position nor resolves all such Disputed Items in favor of the Parent’s position (the Purchase Price so determined is referred to herein as the “Actual Value”), then that fraction of the fees and expenses of the Selected Accountant equal to (x) the difference between the High Value and the Actual Value over (y) the difference between the High Value and the Low Value shall be paid by Parent and Buyer shall be responsible for the remainder of the fees and expenses of the Selected Accountant.

1.6 Withholding. Buyer shall be entitled to deduct and withhold any Taxes from any amount otherwise payable under this Agreement such amounts as it reasonably determines that it is required by Legal Requirements to deduct and withhold with respect to the making of such payment. To the extent that Buyer so withholds any such amounts, such amounts shall be (A) paid over to the appropriate Governmental Authority and (B) treated for all purposes of this Agreement as having been paid to the applicable Person in respect of which such deduction and withholding was made. For the avoidance of doubt, Buyer and Seller agree that VAT, which is governed by Section 9.2(a), does not constitute a withholding Tax for purposes of this section.

ARTICLE II

REPRESENTATIONS AND WARRANTIES OF PARENT

Except as set forth in the Disclosure Letter (subject to Section 10.12), dated as of the date of this Agreement, delivered by Parent to Buyer contemporaneously with the delivery of this Agreement (the “Disclosure Letter”), Parent hereby represents and warrants to Buyer as follows:

2.1 Organization and Good Standing.

(a) Parent is a corporation validly existing and in good standing under the laws of the State of Delaware. Each of the other Sellers is a corporation (or other Entity) validly existing and (if such Entity is organized in a jurisdiction in which the concept of good standing or its functional equivalent is applicable) in good standing or its functional equivalent under the laws of its jurisdiction of organization. Schedule 2.1 of the Disclosure Letter lists each Company and each Subsidiary of the Companies (together with the Companies, the “Transferred Companies”) and the business entity form and place of organization for each of the Transferred Companies.

(b) Each Transferred Company is (i) validly existing and (if such Transferred Company is organized in a jurisdiction in which the concept of good standing or its functional equivalent is applicable) in good standing or its functional equivalent under the laws of its jurisdiction of organization, and (ii) qualified to do business and in good standing or its functional equivalent in each jurisdiction in which the Assets owned, leased or operated by it or the nature of the business conducted by it requires such qualification, in each case, if such concepts or their functional equivalent are applicable in such jurisdiction, except, if applicable, for such failures to be so qualified and in good standing or its functional equivalent which are not material to the operation of the Business, taken as a whole. Each Transferred Company has all requisite corporate (or other Entity) authority under the Legal Requirements pursuant to which it is organized to own, lease or operate the Assets owned, leased or operated by it and to carry on the business as it is now being conducted by it. Schedule 2.1(b) of the Disclosure Letter sets forth each jurisdiction in the United States in which each of the Transferred Companies is licensed or qualified to do business.

(c) Parent has made available to Buyer true and complete copies of each Transferred Company’s certificate of incorporation and by-laws (or comparable organizational documents) and all amendments thereto (the “Organizational Documents”) to the date of this Agreement, as in effect on the date of this Agreement. The Organizational Documents of each of the Transferred Companies are in full force and effect and the Transferred Companies are not in violation of their respective Organizational Documents.

2.2 Capitalization. Schedule 2.2 of the Disclosure Letter sets forth with respect to each Transferred Company the authorized capital stock or other equity interests of each Transferred Company and the number of shares of such stock or equity interests that are issued and outstanding as of the date of this Agreement. The ownership as of the date of this Agreement and following the consummation of the Restructurings of all issued and outstanding shares or other equity interests owned by the applicable Seller or Transferred Company in each Transferred Company is set forth on Schedule 2.2 of the Disclosure Letter. All of the Shares and the Subsidiary Shares have been validly authorized and issued, are fully paid and, in respect of such jurisdictions where such concept is applicable, nonassessable and have not been issued in violation of any preemptive rights. Except as contemplated by this Agreement, there is no security, option, warrant, right, call, subscription agreement, commitment or understanding of any nature whatsoever to which a Seller or a Transferred Company is a party, that directly or indirectly (a) calls for the issuance, sale, pledge or other disposition of any shares of capital stock

or other equity interests of a Transferred Company or any securities convertible into, or other rights to acquire, any shares of capital stock or other equity interests of a Transferred Company, (b) obligates a Transferred Company to participate in or make any capital contribution or future equity investment in any Persons, (c) obligates a Transferred Company to grant, offer or enter into any of the foregoing or (d) relates to the voting or control of such capital stock or other equity interests. No Transferred Company is a party to, or otherwise bound by, any voting trust, proxy or other agreement, restricting or otherwise relating to the voting, dividend rights or disposition of any Shares or any Subsidiary Shares. None of the Transferred Companies own, directly or indirectly, any capital stock, membership interest, partnership interest, joint venture interest or other equity interests in any Person, other than a Transferred Company. Following the consummation of the Restructurings, the applicable Seller shall own the Shares to be sold by such Seller free and clear of any Encumbrances, other than Permitted Encumbrances, and the Sellers will transfer to Buyer at the Closing, good title to the Shares, free and clear of any Encumbrances.

2.3 Authority, Approvals and Consents.

(a) Parent has the corporate power and authority to execute, deliver and perform this Agreement and the Ancillary Documents to be executed and delivered by Parent and to consummate the transactions contemplated hereby and thereby. At the Closing, each other Seller will have the corporate (or other Entity) power and authority to execute, deliver and perform the Ancillary Documents to be executed and delivered by such Seller and to consummate the transactions contemplated hereby and thereby. The execution, delivery and performance by Parent of this Agreement and each of the Ancillary Documents to which it will at Closing be a party, and the consummation by Parent of the transactions contemplated hereby and thereby have been, and at the Closing the execution, delivery and performance by each other Seller of the Ancillary Documents to which it is a party and the consummation of the transactions contemplated hereby and thereby by such other Sellers will have been, duly authorized and approved by the board of directors (or comparable governing body) of each of the Sellers and no other corporate (or other Entity) proceedings on the part of Sellers or the shareholders or other equity holders of Sellers are necessary to authorize and approve this Agreement and the Ancillary Documents to be executed and delivered by Sellers and the transactions contemplated hereby and thereby. This Agreement has been duly executed and delivered by Parent, and the Ancillary Documents to be executed and delivered by any Seller at the Closing will be duly executed and so delivered by such Seller. This Agreement constitutes, and at the Closing each Ancillary Document to be executed and delivered by any Seller will constitute, a valid and binding obligation of such Seller, enforceable against such Seller in accordance with its terms, except as such enforceability may be limited by the Bankruptcy and Equity Exceptions.

(b) The execution, delivery and performance by Parent of this Agreement and by Parent and the applicable Sellers of the Ancillary Documents to be executed and delivered by Parent or any of the other Sellers and the consummation by Parent and the applicable Sellers of the transactions contemplated hereby and thereby, do not and will not:

Neither party to this Agreement shall agree to any voluntary extension or delay of any waiting periods or applicable suspensory periods during which the Closing cannot occur under the HSR Act or under any Applicable Non-U.S. Antitrust Law, or otherwise withdraw its notification and report form under either the HSR Act or any Applicable Non-U.S. Antitrust Law, in each case, unless both Parent and Buyer have given their prior written consent to such extension, delay or withdrawal.

(b) Buyer and Parent shall use their commercially reasonable efforts to defend any challenge, administrative process or litigation brought by any Governmental Authority or third person seeking to restrain or prohibit any of the transactions contemplated by this Agreement under any Antitrust Laws, and to vacate any relevant restraining order, injunction or adverse decision that prohibits the consummation of the transactions contemplated by this Agreement, in each case, so as to permit the transactions contemplated by this Agreement to be consummated as expeditiously as possible.

(c) Subject to the terms and conditions herein provided, and without limitation by the foregoing, Buyer shall offer to take, or cause to be taken, all commercially reasonable actions and do, or cause to be done, all other commercially reasonable things necessary, proper or advisable to eliminate any objection that any Governmental Authority has to the transactions contemplated by this Agreement under applicable Antitrust Laws and to consummate the transactions contemplated by this Agreement, in each case, as expeditiously as possible.

(d) Subject to applicable Legal Requirements, the preservation of the attorney-client privilege and the instructions of any Governmental Authority, Parent and Buyer shall each keep the other informed of the status of matters relating to the completion of the transactions contemplated by this Agreement, including promptly furnishing the other with copies of notices or other communications between Parent or Buyer, as the case may be, or any of their respective Affiliates (with any competitively sensitive information being provided on an external counsel basis only and excluding any internal business documents of Buyer), and any third Person and/or any Governmental Authority with respect to such transactions. Parent and Buyer shall permit counsel for the other party reasonable opportunity to review in advance, and consider in good faith the views of the other party in connection with, any proposed written communication to any Governmental Authority with respect to such transactions. Parent and Buyer each agree not to participate in any substantive meeting or discussion, either in person or by telephone, with any Governmental Authority in connection with the transactions contemplated by this Agreement unless it consults with the other party in advance and, to the

extent not prohibited by such Governmental Authority, gives the other party the opportunity to attend and participate.

4.6 Use of Name.

(a) Buyer agrees that (except as expressly set forth in this Section 4.6(a)), after the Closing neither Buyer nor its Affiliates (including the Transferred Companies) shall have any rights in and to the xxxx “Xxxxxxxx” or any Trademark related thereto or containing or comprising any of the foregoing, including any xxxx or term confusingly similar thereto or derivative thereof (the “Seller Marks”), and will not at any time after the Closing market, promote, advertise or offer for sale any products, goods or services utilizing any of the Seller Marks or otherwise hold itself out as having any affiliation with Parent or any of its Affiliates. Buyer agrees that, after the expiration of the license contained in this Section 4.6(a), if any of the Business Assets, including any promotional materials, bear the Seller Marks, Buyer shall, prior to distributing, selling or otherwise making use (other than internal use) of such Business Assets, remove, delete or render illegible the Seller Marks as they may appear on such Business Assets; provided that Buyer shall use its commercially reasonable efforts to remove, delete or render illegible any Seller Marks from any Business Assets used for internal use as promptly as practicable following the expiration of such license. Notwithstanding the foregoing, Parent hereby grants to Buyer and the Transferred Companies a non-exclusive, non-assignable, fully paid-up, royalty-free, worldwide license for a period of one hundred and twenty (120) days after the Closing Date to use the Seller Marks to distribute, sell and offer for sale, products and services, including for the display of marketing, promotional and advertising materials, business cards, stationery, packaging materials, displays, signs, promotional materials and other similar materials that include one or more of the Seller Marks (collectively, “Supplies”), provided such Supplies (i) were included within the inventory of Business Assets as of the Closing, (ii) are used solely in connection with the promotion, marketing, advertising and sale of the Business’ products of the type sold, and in a manner consistent with that used, prior to the Closing and (iii) clearly indicate that (x) the Transferred Companies are not affiliated with Parent or any of Parent’s Affiliates and (y) the inclusion of the Seller Marks in the Supplies shall not be construed as an endorsement of any of the Business’ products by Parent or any of Parent’s Affiliates. Buyer shall indemnify and hold harmless the Seller Indemnitees against all Losses asserted against or imposed upon them as a consequence of the use of the Seller Marks by Buyer and its Affiliates (including the Transferred Companies) following the Closing, except for any Losses asserted against or imposed upon them as a consequence of any claim that the use of the Seller Marks infringes the rights of any third Person.

(b) Buyer agrees to cause each Transferred Company whose name includes the name “Rockwood” to, promptly following the Closing, and in any event within fifteen (15) Business Days after the Closing Date, change its name such that its name does not include the name “Rockwood.”

4.7 Notification of Certain Matters. Between the date of this Agreement and the Closing, (a) Parent will give prompt notice in writing to Buyer of (i) any written notice or other written communication it receives from any Governmental Authority in connection with the transactions contemplated by this Agreement, to the extent permitted by Legal Requirements,

(ii) any written notice from any Person alleging that the Consent or Approval of such Person is or may be required in connection with the transactions contemplated by this Agreement or any of the Ancillary Documents, or (iii) any specific event or circumstance of which it has Knowledge, or of which it receives written notice, that (x) has had or could reasonably be expected to have, individually or in the aggregate, taken together with other events or circumstances, a Material Adverse Effect or (y) will result, or has a reasonable prospect of resulting, in the failure to satisfy a condition specified in Article V by the Outside Date, and (b) Buyer will give prompt notice in writing to Parent of (i) any written notice or other written communication it receives from any Governmental Authority in connection with the transactions contemplated by this Agreement, to the extent permitted by Legal Requirements, (ii) any written notice from any Person alleging that the Consent or Approval of such Person is or may be required in connection with the transactions contemplated by this Agreement or any of the Ancillary Documents, or (iii) any specific event or circumstance of which it has knowledge, or of which it receives notice, that will result, or has a reasonable prospect of resulting, in the failure to satisfy a condition specified in Article VI by the Outside Date; provided, however, that the delivery of any notice by Parent and the information or knowledge obtained by Buyer pursuant to this Section 4.7 shall not (i) affect or be deemed to affect or modify any representation, warranty, covenant or agreement contained herein, the conditions to the obligations of the parties to consummate the Closing in Articles V and VI or otherwise prejudice in any way the rights and remedies of Buyer hereunder, including pursuant to Article VII, (ii) be deemed to affect or modify Buyer’s reliance on the representations, warranties, covenants and agreements made by Seller in this Agreement or (iii) be deemed to amend or supplement the Disclosure Letter or prevent or cure any misrepresentation, breach of warranty or breach of covenant by Parent.

4.8 Retention of Books and Records. Buyer will retain, or cause its Affiliates (including the Transferred Companies) to retain, all books, records and other documents pertaining to the Business in existence on the Closing Date and to make the same available after the Closing Date for examination and copying by Parent or its representatives, at Parent’s expense, upon reasonable notice and subject to entry into customary confidentiality obligations. Buyer agrees that no such books, records or documents will be destroyed by Buyer or its Affiliates (including the Transferred Companies) until the later of (i) seven (7) years following the Closing or (ii) the expiration of the statute of limitations for the assessment of Taxes in the jurisdiction to which such books, records and documents relate, and that thereafter no such books, records or documents will be destroyed without first advising Parent in writing and providing to Parent a reasonable opportunity to obtain possession or make copies thereof at Parent’s expense.

4.9 Permits. Buyer shall be responsible for effecting all updates and amendments and reissuances of Permits required in connection with or as a result of the transactions contemplated hereby. Parent will, and will cause its Affiliates to, reasonably cooperate with Buyer in effecting such updates, amendments and reissuances.

4.10 Intercompany Agreements.

(a) As of the Closing, all Business Agreements and transactions between Parent and its Affiliates (other than the Transferred Companies) on the one hand, and

the Transferred Companies, on the other hand(other than the Business Agreements or other transactions listed on Schedule 4.10 of the Disclosure Letter) will either be terminated or amended to remove or replace the applicable Transferred Company or Affiliate of Parent, as the case may be, as a party to such agreement, as applicable, without further liability to any Transferred Company that is a party thereto with respect to periods following the Closing.

(b) Parent shall, and shall cause its Affiliates (including the other Sellers and the Transferred Companies) to take such actions as are necessary to ensure that the Retained Cash Balances do not exceed U.S.$10.0 million at Closing; provided that any amounts deemed to be Retained Cash Balances pursuant to Section 4.22 shall not be Retained Cash Balances for these purposes.

4.11 Indebtedness. Prior to the Closing, except for any Indebtedness arising under any Enterprise Agreement, Parent will cause each Transferred Company to pay, discharge, compromise, settle, terminate or otherwise satisfy (or cause to be paid, discharged, compromised, settled, terminated, contributed to the capital of the applicable Transferred Company or otherwise satisfied) in full all Indebtedness of the Transferred Companies, including any intercompany Indebtedness owing from any Transferred Company to Parent or any of its Affiliates (other than the Transferred Companies) and all Indebtedness listed on Schedule 2.5(b) of the Disclosure Letter. In addition, Parent will cause all intercompany Indebtedness owing from Parent or any of its Affiliates (other than the Transferred Companies) to the Transferred Companies to be paid, discharged, compromised, settled, terminated, contributed to the capital of Parent or the applicable Affiliate or otherwise satisfied in full prior to the Closing.

4.12 Guarantees. The parties shall use their commercially reasonable efforts to obtain, on or before the Closing Date, and in any event within ninety (90) days following the Closing Date, the release of each of the obligations of Parent (or any Affiliate thereof, other than the Transferred Companies) to guaranty the liabilities listed on Schedule 4.12 of the Disclosure Letter, and Buyer shall provide such guarantees as shall be reasonably required to obtain such release. Buyer shall indemnify and hold harmless Parent in respect of any liability or expense incurred by Parent (or any Affiliate thereof, other than the Transferred Companies) in respect of any claim made in respect of any such liability or expense arising or incurred after the Closing Date.

4.13 Title Insurance. Prior to the Closing, Parent will cause the Transferred Companies to reasonably cooperate with Buyer in Buyer’s efforts to obtain title insurance or title reports in respect of the Real Property located in the United States. Such cooperation will include the execution of such customary instruments by Parent reasonably requested by Buyer’s title insurance company to enable Buyer to obtain such insurance and desired endorsements; provided, however, that Parent and its Affiliates (other than the Transferred Companies) shall not be required to execute any instrument which expands in any way the representations and warranties contained herein or the liabilities of Parent hereunder (for purposes of this Agreement, any instrument executed by the Transferred Companies pursuant to this Section 4.13 shall be deemed to have been executed and delivered following the Closing). The premiums for such title insurance will be Buyer’s responsibility.

4.14 Restructurings. Parent shall cause the Restructurings to be consummated in accordance with Schedule A-2 of the Disclosure Letter and shall use commercially reasonable efforts to consummate the Restructurings prior to the date the Closing would otherwise be required to occur pursuant to this Agreement without giving effect to the conditions to the consummation of the Closing set forth in Sections 5.5 and 6.4. All fees, expenses and other liabilities, other than Taxes (liability for which Buyer is indemnified for to the extent provided in Section 9.1(a)(iii)), in connection with the Restructurings shall be Parent’s responsibility.

4.15 Restrictive Covenants.

(a) Parent agrees, to the maximum extent not violative of applicable Legal Requirements, that for a period of two (2) years following the Closing Date, Parent will not, nor will it permit any of its Affiliates to, directly or indirectly, solicit for employment or hire any Business Employee who is or has been employed by any of the Transferred Companies, at, or at any time within one (1) year prior to, the time of the act of solicitation; provided, however, that (i) general solicitations, such as through newspaper advertisements not directed at Business Employees, will not be deemed to violate this Section 4.15(a) and (ii) this Section 4.15(a) shall not apply in respect of any Business Employee whose employment with Buyer or any of its Affiliates, including the Transferred Companies, is terminated by Buyer or any of its Affiliates.

(b) Parent agrees, to the maximum extent not violative of applicable Legal Requirements, that for a period of three (3) years following the Closing Date, Parent will not, and will not permit any of its Affiliates to, engage in the Business in any country (the “Restricted Territory”) in which the Business conducts operations as of the Closing Date (the “Restricted Business”); provided, however, that nothing herein shall be construed to prevent Parent or its Affiliates from (w) acquiring or owning, directly or indirectly, up to 5% of a class of equity securities issued by any Person that engages, directly or indirectly, in the Restricted Business in the Restricted Territory that is publicly traded or listed on any stock exchange or automated quotation system, (x) conducting any business conducted by them on the Closing Date (other than those conducted through the Transferred Companies), (y) acquiring any Entity or business or owning such acquired Entity or business that, directly or indirectly, engages in the Restricted Business in the Restricted Territory; provided, however, that if more than 15% of the aggregate net revenue derived from the last complete fiscal year of such acquired Entity or business (calculated on a consolidated basis) was attributed to the Restricted Business in the Restricted Territory, Parent will or will cause its applicable Affiliate to, as the case may be, use commercially reasonable efforts to dispose of such portion of such Entity or business to the extent that it engages in the Restricted Business in the Restricted Territory within nine (9) months of the consummation of such acquisition by Parent or such Affiliate, or (z) performing its obligations under this Agreement or any Ancillary Document.

(c) Notwithstanding anything herein to the contrary, the restrictions set forth in Sections 4.15(a) and 4.15(b) will apply only to Rockwood and Entities “controlled by” (as such term is defined in the definition of the term “Affiliate”) Rockwood, and shall not apply to any third Person or the Affiliates of such third Person (other than Rockwood, and any Entities “controlled” by Rockwood) that acquires Rockwood or any Entities “controlled” by

Rockwood, whether as a result of a merger, consolidation, other business combination, or acquisition of all or substantially all of its assets or business.

(d) Parent acknowledges and agrees that the covenants set forth in this Section 4.15 are reasonable in geographical and temporal scope and in all other respects, and any violation of these restrictions would cause substantial injury to Buyer and that Buyer would not have entered into this Agreement without receiving the additional consideration offered by Parent in binding itself and its Affiliates to these restrictions. In the event of a breach or a threatened breach by Parent or any of its Affiliates of these restrictions, Buyer will be entitled to seek an injunction restraining Parent or such Affiliate from such breach or threatened breach without the necessity of proving the inadequacy as a remedy of money damages; provided, however, that the right to injunctive relief will not be construed as prohibiting Buyer from pursuing any other available remedies, whether at law or in equity, for such breach or threatened breach.

(e) If any court determines that any provision included in this Section 4.15 is unenforceable, such court will have the power to reduce the duration or scope of such provision, as the case may be, or terminate such provision and, in reduced form, such provision shall be enforceable; it is the intention of the parties hereto that the foregoing restrictions shall not be terminated, unless so terminated by a court, but shall be deemed amended to the extent required to render them valid and enforceable, such amendment to apply only with respect to the operation of this Agreement in the jurisdiction of the court that has made the adjudication.

4.16 Cooperation in Litigation. Buyer and Parent shall (and shall cause their respective Affiliates to) reasonably cooperate with each other at the requesting party’s expense in the prosecution or defense of any claim, litigation or other proceeding arising from or related to the conduct of the Business prior to the Closing and involving one or more third Persons. The party requesting such cooperation shall pay the reasonable out of pocket expenses incurred in providing such cooperation (including reasonable legal fees and disbursements) by the party providing such cooperation and by its Affiliates and its and their officers, directors, employees and agents, but shall not be responsible for reimbursing such party or its Affiliates or its and their officers, directors, employees and agents for their time spent in such cooperation.

4.17 Assistance Obligations of Buyer. After the Closing, Buyer will (and will cause the Transferred Companies and its other Affiliates to) reasonably assist Parent and its Affiliates in preparing information for various Governmental Authorities or third party insurance providers under policies held by Parent or its Affiliates after the Closing to the extent that such information relates to the transactions contemplated by this Agreement, the Business, the Business Assets and/or the liabilities of the Business. Such information includes, but is not limited to, information required by Parent and its Affiliates to (i) comply with their financial reporting requirements and (ii) to submit any claims that would reasonably be expected to be covered under the insurance policies of Parent or its Affiliates or their respective self-insurance programs in respect of events, circumstances and occurrences prior to Closing. Parent shall reimburse Buyer for all reasonable out-of-pocket expenses (excluding internal costs) actually

incurred by Parent and its Affiliates in connection with the compliance by Parent with its obligations under this Section 4.17.

4.18 Further Assurances. Any time after the Closing, Parent and Buyer will, and Buyer will cause the Transferred Companies to, promptly execute, acknowledge and deliver any other assurances or documents reasonably requested by Buyer or Parent, as the case may be, to satisfy or in connection with its obligations hereunder or to consummate or implement the transactions and agreements contemplated hereby.

4.19 Insurance. From and after the Closing Date, the Transferred Companies shall cease to be insured by Parent’s or Parent’s Affiliates’ (other than the Transferred Companies’) insurance policies or by any of Parent’s or Parent’s Affiliates’ (other than the Transferred Companies’) self-insured programs. From and after the Closing, Parent shall be responsible for the administration and payment of all claims made by any of the Transferred Companies prior to the Closing under any of Parent’s or Parent’s Affiliates’ (other than the Transferred Companies) insurance policies or self-insured programs, and Buyer and its Affiliates (including the Transferred Companies) shall reasonably cooperate with any reasonable requests of Parent in connection with administration and payment of such claims. For the avoidance of doubt, following the Closing, Parent and its Affiliates shall retain all rights to control its insurance policies and programs, including the right to exhaust, settle, release, commute, buy back or otherwise resolve disputes with respect to any of its insurance policies and programs, notwithstanding whether any such policies or programs apply to any liabilities of Buyer or the Transferred Companies. Prior to and after the Closing, Parent and its Affiliates (including, prior to the Closing Date, the Transferred Companies) shall reasonably cooperate with Buyer to assist Buyer in obtaining replacement insurance policies.

4.20 Privileged Matters; Waiver of Conflicts. The parties hereto acknowledge and agree that the information relating to or arising out of the legal advice or services that have been or will be provided prior to the Closing Date for the benefit of both Parent or its Affiliates (other than the Transferred Companies) and the Transferred Companies shall be subject to a shared privilege between Parent, on the one hand, and the Transferred Companies, on the other hand, and Parent and the Transferred Companies shall have equal right to assert all such shared privileges in connection with privileged information under any applicable Legal Requirements and no such shared privilege may be waived by (a) Parent without the prior written consent of Buyer or (b) by Buyer or any Transferred Company without the prior written consent of Parent; provided, however, that any information relating to or arising out of any legal advice or services provided, whether before or after the Closing Date, with respect to any matter for which an Indemnifying Party has an indemnification obligation hereunder, shall be subject to the sole and separate privilege of such Indemnifying Party, and such Indemnifying Party shall be entitled to control the assertion or waiver of all such separate privileges under any applicable Legal Requirements in connection with any privileged information, whether or not such information is in the possession of or under the control of any Indemnified Party. Buyer, on behalf of itself and its Affiliates, including, following the Closing, the Transferred Companies, hereby irrevocably waives any conflicts arising out of the representation of the Transferred Companies by Xxxxxx Xxxxxxx & Xxxx LLP or Xxxxxxx Xxxx & Xxxxxxxxx LLP prior to the Closing that may, following the Closing, prevent such firms from representing Parent and its Affiliates in any matter

(including with respect to claims and legal proceedings arising under or with respect to this Agreement and the transactions contemplated hereby).

4.21 Post-Closing Confidentiality. For five (5) years following the Closing, Parent shall keep confidential, and shall cause its Affiliates and its and their representatives to keep confidential, all information relating to the Business, the Transferred Companies and the Business Assets (“Confidential Information”), except (a) with the prior written consent of Buyer, (b) to the extent necessary to comply with applicable Legal Requirements, including federal securities laws, the valid order of a court of competent jurisdiction or any judicial or administrative process, in which event, to the extent permitted by such Legal Requirement, order or process, Parent shall notify Buyer as promptly as practicable (and, if possible, prior to the making of such disclosure) and disclose only that information that Parent determines (with the advice of counsel) is required by such applicable Legal Requirements to be disclosed, (c) to the extent such Confidential Information is available to the public through no fault of the Parent or any Affiliate of Parent, (d) to the extent such Confidential Information was or becomes available to Parent or any Affiliate of Parent from a third Person who is under no confidential or fiduciary obligation to Buyer or its Affiliates with respect to such Confidential Information, (e) to the extent such Confidential Information is independently developed by Parent or its Affiliates without violating this Section 4.21 or (f) to the extent such Confidential Information is used in the enforcement of any of the rights of Parent or any of its Affiliates under this Agreement or the other Ancillary Documents or in the defense of any action, suit, litigation, investigation or proceeding brought against Parent or one of its Affiliates.

4.22 Enterprise Agreements

(a) Parent shall cause the Enterprise Agreements to be terminated by RSGG with effect as near to (but not after) the Closing Date as is reasonably practicable (the effective date of such termination, the “Termination Date”). Within seventy-five (75) days following the Closing Date, Buyer shall cause Xxxxxxxx Xxxx Additives to prepare and complete, in cooperation with RSGG, the annual financial accounts of Xxxxxxxx Xxxx Additives for the fiscal period commencing on January 1 of the calendar year during which the Termination Date occurs and ending as of the Termination Date (the “German Controlled Entity Profit Pooling Accounts”), which accounts shall be prepared in accordance with generally accepted accounting principles in Germany as in effect on the Termination Date and, to the extent permitted by applicable Legal Requirements, consistent with the past practices of Xxxxxxxx Xxxx Additives, including by applying the policies, procedures, practices and elections applied by Parent in the preparation of the annual financial accounts of Xxxxxxxx Xxxx Additives prior to the Closing Date on a consistent basis. Any amounts included in the German Controlled Entity Profit Pooling Accounts as payable by RSGG to Xxxxxxxx Xxxx Additives as of the Termination Date under an Enterprise Agreement shall be treated as Retained Cash Balances for purposes of determining the Purchase Price, and such amount shall be included in the Retained Cash Balances included in the Final Closing Statement delivered by Buyer to Parent pursuant to Section 1.5(c), and any disputes over such amount shall be resolved pursuant to Section 1.5. Any amounts included in the German Controlled Entity Profit Pooling Accounts as payable by Xxxxxxxx Xxxx Additives to RSGG under an Enterprise Agreement as of the Termination Date shall be treated as Transferred Company Indebtedness for purposes of

determining the Purchase Price, and such amount shall be included in the Transferred Company Indebtedness included in the Final Closing Statement delivered by Buyer to Parent pursuant to Section 1.5(c), and any disputes over such amount shall be resolved pursuant to Section 1.5. Promptly, and in any event, within two (2) Business Days following the final determination of the Purchase Price pursuant to Section 1.5, (i) Buyer shall cause Xxxxxxxx Xxxx Additives to pay to RSGG any amounts payable to RSGG under the Enterprise Agreements as of the Termination Date, and (ii) Parent shall cause RSGG to pay to Xxxxxxxx Xxxx Additives any amounts payable to Xxxxxxxx Xxxx Additives under the Enterprise Agreements as of the Termination Date.

(b) Following the Closing Date, Buyer shall not, and shall cause its Affiliates (including Xxxxxxxx Xxxx Additives) not to, amend, re-file or otherwise modify the German Controlled Entity Profit Pooling Accounts without the prior written consent of Parent (not to be unreasonably withheld, delayed or conditioned). Upon Parent’s reasonable request, Buyer shall, and shall cause Xxxxxxxx Xxxx Additives to, amend the German Controlled Entity Profit Pooling Accounts in accordance with the written instructions of Parent, if and to the extent required in order to maintain the fiscal unity of Xxxxxxxx Xxxx Additives with RSGG and its Affiliates in accordance with the applicable Enterprise Agreement for any period ending on or prior to the Termination Date. In the event that, following the Closing Date, a Governmental Authority of competent jurisdiction makes a determination which is not subject to appeal that the amount of profits transferred or the losses paid, as the case may be, under an Enterprise Agreement with respect to any period ending on or prior to the Termination Date were not transferred or paid, as the case may be, in accordance with the applicable Enterprise Agreement or applicable Legal Requirements, (i) Parent will cause RSGG to pay any such amounts so determined to be payable by RSGG to Xxxxxxxx Xxxx Additives, or (ii) Buyer shall cause Xxxxxxxx Xxxx Additives to pay such amounts so determined to be payable by Xxxxxxxx Xxxx Additives to RSGG, as the case may be, by wire transfer of immediately available funds to a bank account designated in writing by Parent or Buyer, as the case may be, to the other party. Concurrently with any payment by RSGG to Xxxxxxxx Xxxx Additives pursuant to the previous sentence, Buyer shall pay to Parent an amount equal to such payment and, concurrently with any payment by Xxxxxxxx Xxxx Additives to RSGG, as the case may be, pursuant to the previous sentence, Parent shall pay to the Buyer an amount equal to such payment, in each case, by wire transfer of immediately available funds to a bank account designated in writing by Parent or Buyer, as the case may be, to the other party.

4.23 Parent Release. Except (a) for the rights and remedies in respect of this Agreement and the Ancillary Documents, (b) with regard to those items listed on Schedule 4.10 of the Disclosure Letter or (c), with respect to any director, officer or employee of a Transferred Company, for any breaches or violations of the Rockwood Code of Business Conduct and Ethics or similar policies, effective upon the Closing, Parent, on behalf of itself and each of its Affiliates (other than the Transferred Companies), hereby irrevocably and unconditionally releases, discharges and covenants not to xxx and otherwise agrees not to enforce any claim, cause of action, right, title or interest against, any Transferred Company and each director, officer and employee of each Transferred Company and their respective successors and permitted assigns of, from and with respect to any and all claims, charges, complaints, debts, covenants, agreements, obligations, liabilities, actions or demands of any kind or character,

based upon any fact or circumstance, whether known or unknown, suspected or unsuspected, which presently exists or has ever existed in the past, that Parent or such of its Affiliates have or may have in any manner whatsoever, either singly or jointly with others against any of such Persons.

4.24 ECC America Agreement. Following the date of this Agreement and prior to the Closing Date, Parent shall use its commercially reasonable efforts to obtain the consent to assign in part the ECC America Agreement to Buyer or one if its Affiliates from the counterparties to such agreement; provided that such efforts shall not include an obligation by Parent or any of its Affiliates to pay any consideration or other amounts to any third Person in connection with obtaining such consent. In the event the ECC America Agreement is not assigned in part to Buyer or one of its Affiliates at the Closing, following the Closing and until the ECC America Agreement is assigned in part to Buyer or one of its Affiliates, Parent shall, at the cost and expense of Buyer and its Affiliates, use its commercially reasonable efforts to provide, and shall cause its Affiliates to use their respective commercially reasonable efforts to provide, Buyer and its Affiliates, including Southern Clay Products, the benefits under the ECC America Agreement to which Buyer and its Affiliates, including Southern Clay Products, are entitled, including using its commercially reasonable efforts to pursue any claims for indemnification available to Buyer and its Affiliates, including Southern Clay Products, under the ECC America Agreement in accordance with the terms thereof. Buyer agrees to provide, and to cause its Affiliates, including Southern Clay Products, to provide, such cooperation and information reasonably requested by Parent in connection with such indemnification claims.

4.25 UK Pensions. Parent will use reasonable efforts to reach an agreement with the trustees of the U.K. Retirement Plan prior to the Closing under which any and all liabilities of Rockwood Additives Limited in relation to the U.K. Retirement Plan are apportioned to Parent or any of its Affiliates other than the Transferred Companies. Notwithstanding the foregoing, if Rockwood Additives Limited, Buyer or any of their Affiliates following the Closing are or may become required to pay any amount to or in respect of the U.K. Retirement Plan (whether under section 75 or 75A of the Pensions Xxx 0000 or otherwise), Parent acknowledges that the relevant provisions of Section 8.2 of this Agreement shall apply.

4.26 Post-Closing Asset Transfers. If after the Closing, either Buyer or Parent in good faith identifies any Asset (other than any Administrative Asset) of Parent or its Affiliates which is primarily used or held for use primarily in the operation of the Business as the Business is conducted as of the date of the Agreement that is not owned by a Transferred Company at the Closing, then either Buyer or Parent, as applicable, will provide written notice to the other Party identifying such Asset, then Parent will, or will cause its Affiliates to, as promptly as practicable and at no further cost to Buyer, transfer, convey, assign, deliver, or cause to be transferred, conveyed, assigned, or delivered to Buyer, all of the right, title and interest of Parent and its Affiliates in and to such Asset.

(b) no Indemnified Party will be entitled to recover indirect, special, consequential, incidental, punitive or business interruption damages, or lost revenues, profits, cost savings or synergies pursuant to Sections 8.2 or 8.3, except to the extent such Losses were (i) other than in the case of punitive or special damages, reasonably foreseeable or (ii) actually paid to a third Person (including pursuant to a binding contractual obligation) pursuant to a final, non-appealable award, decree or settlement in any Third-Party Claim.

(c) no claim for indemnification may be made by a Buyer Indemnitee pursuant to Section 8.2 or by a Seller Indemnitee pursuant to Section 8.3 unless written notice of such claim (describing the facts or events, the existence or occurrence of which constitute or have resulted in the alleged inaccuracy or breach of a representation or warranty made in this

Agreement or which otherwise form the basis of the claim with reasonable specificity, to the extent known) has been given to the party from whom indemnification is sought (the “Indemnifying Party”) during the relevant survival period set forth in Section 8.1 (which, for purposes of Sections 8.2(a) and 8.3(a), will be the survival period of the representation and warranty alleged to have been breached);

(d) Parent shall have no liability pursuant to Section 8.2(a): (i) for any Losses with respect to an individual matter or series of related matters until the cumulative aggregate amount of the Losses with respect to such matter or series of related matters arising out of the same facts or circumstances exceeds U.S.$150,000 (the “Threshold Amount”), in which case the amount of all such Losses (including those that are less than the Threshold Amount) shall be included for purposes of computing the Losses that are indemnifiable hereunder and/or applicable against the Basket Amount pursuant to clause (ii) below; and (ii) until the aggregate amount of the Losses of the Buyer Indemnitees for which indemnification would otherwise be available under Section 8.2(a) exceeds 0.5 % of the Purchase Price (excluding Retained Cash Balances and Transferred Company Indebtedness) (the “Basket Amount”), after which Parent will be obligated to indemnify for only that portion of such Losses of the Buyer Indemnitees that exceed the Basket Amount; provided that the limitations set forth in subclause (ii) of this clause (d) shall not apply to Losses incurred by a Buyer Indemnitee by reason of any inaccuracy or breach of a Specified Representation; and

(e) Parent shall have no liability pursuant to Section 8.2 for any Loss to the extent a reserve with respect to such Loss is included in or taken into account in the calculation or determination of Closing Working Capital, Capex Shortfall or Transferred Company Indebtedness.

(f) Notwithstanding any other provision of this Agreement, Parent’s obligations under Section 8.2(a) in respect of any asserted breach or inaccuracy of the representations and warranties set forth in Section 2.14 shall, to the extent such obligations involve a Remedial Action, be limited to the minimum reasonable cost approach to such Remedial Action, taking into account Buyer’s or its successor’s continued industrial use of the relevant property or facility, that is legally available (or otherwise required by any Governmental Authority).

(g) Parent shall have no liability for Losses relating to any Environmental Condition (i) under Section 8.2(a)-(j) to the extent occurring as a result of or triggered by the closure, decommissioning or demolition after the Closing of any part of any facility or structure of any Transferred Company or (ii) under Section 8.2 to the extent occurring as a result of or triggered by any sampling, monitoring, testing, or surface or subsurface investigation conducted after the Closing that is not (A) expressly required pursuant to an Environmental Requirement of any Governmental Authority (except where the Governmental Authority has requested such Remedial Action by reason of a request initiated by a Buyer or its Affiliates or its or their representatives) or (B) otherwise the reasonable action of a prudent businessperson taken for a reason other than the assertion of an indemnity claim under this Agreement.

(h) For purposes of Section 8.2, Losses shall not include (i) any Losses arising from any change to a non-industrial use of the Real Property, (ii) any Losses resulting from any increase, worsening or other adverse impact on any Environmental Condition that arises from any act or omission attributable to Buyer or any Transferred Company (and their Affiliates, agents and contractors and Persons acting on their behalf) following the Closing that is a failure to act reasonably with respect to an Environmental Condition, and (iii) any expense related to management or employee time (whether opportunity costs, direct costs or otherwise).

(i) For the purposes of determining whether a breach of representation or warranty has occurred for the purposes of Section 8.2(a) or 8.3(a), as the case may be, and calculating the amount of Losses related thereto, any qualification as to materiality or Material Adverse Effect contained in Articles II and III shall be disregarded (it being understood that the word “Material” in the defined term “Material Contract(s)” and the qualifications as to “material”, “material respects” or “Material Adverse Effect” contained in Sections 2.4(a) (second sentence), 2.6(a)(ii), 2.11(c), 2.12(a), and 4.3(b) (to the extent incorporated into Section 2.6(b)) shall not be disregarded for any of such purposes).

(j) Notwithstanding anything to the contrary herein, except for the qualification of the representations and warranties in Articles II and III by the Disclosure Letter as expressly provided for in Section 10.10(b), the rights and remedies of the Indemnified Parties after the Closing shall not be limited by the fact that any Indemnified Party had actual or constructive knowledge (regardless of whether such knowledge was obtained through such Indemnified Party’s own investigation or through disclosure by Parent, Buyer or any third party, as applicable) of any breach, event or circumstance, whether before or after the Closing.

(k) For purposes of Section 8.2(k):

(i) Parent shall have no liability for any Losses with respect to an individual Environmental Condition or series of related Environmental Conditions until the cumulative aggregate amount of the Losses with respect to such Environmental Condition or series of related Environmental Conditions arising out of the same facts or circumstances exceeds U.S.$50,000, after which Parent will be obligated to indemnify for only that portion of such Losses of the Buyer Indemnitees that exceed such amount;

(ii) Parent shall be liable only for (A) 75% of the Losses of the Buyer Indemnitees incurred prior to and including the tenth (10th) anniversary of the Closing Date and (B) 50% of the Losses of the Buyer Indemnitees incurred after the tenth (10th) anniversary of the Closing Date and prior to and including the fifteenth (15th) anniversary of the Closing Date;

(iii) Parent shall not be liable for any Losses of the Buyer Indemnitees incurred following the fifteenth (15h) anniversary of the Closing Date; and

(iv) Buyer Indemnitees shall not be entitled to indemnification under clauses (d), (e), (g) or (j) of Sections 8.2 for any Pre-Closing Widnes Environmental Condition.

(l) Notwithstanding anything to the contrary in this Agreement, including Article VIII, Parent shall have no liability for any Losses incurred by the Buyer Indemnitees based upon, resulting from or arising out of the remediation, removal or disposal of any asbestos at the facility of the U.K. Company in Widnes, Cheshire, United Kingdom identified in the surveys described in Schedule 2.14(g) of the Disclosure Letter.

8.5 Mitigation and Recovery from Third Persons.

(a) Buyer and Parent shall each take, and shall cause their respective Affiliates to take, all reasonable steps to mitigate any Loss for which indemnification may be sought hereunder promptly upon a responsible officer of an Indemnified Party or its Affiliates becoming aware of such Loss, and neither Buyer nor Parent shall be liable for any Loss to the extent the Indemnified Party or its Affiliates could have mitigated such Loss by taking reasonable steps after a responsible officer of such Indemnified Party or its Affiliates becomes aware thereof.

(b) The amount of any Loss for which indemnification is provided under this Article VIII (before giving effect to the other limitations on indemnification set forth in this Article VIII) shall be net of any amounts recovered by the Indemnified Party (or any Affiliate thereof) under insurance policies, or otherwise recovered by the Indemnified Party (or any Affiliate thereof) from other Persons (in each case, net of any costs incurred for the recovery of such amounts), with respect to such Loss. Buyer and Parent each agree that, unless the other party shall otherwise direct in writing, it will (and cause its Affiliates to) use commercially reasonable efforts to recover any such amounts to the extent such recoveries would reduce amounts required to be paid by the other party pursuant to this Article VIII; provided that, no Indemnified Party (or any Affiliate thereof) shall be required to seek recovery of any Loss for which indemnification is provided under this Article VIII from any employees or managers of any Transferred Companies in order to recover the full amount of the Loss.

8.6 Procedure. Any claim for indemnification under Section 8.2 or Section 8.3 will be made in accordance with this Section 8.6. In the case of any claim for indemnification arising from a claim or demand of a third Person (a “Third-Party Claim”), the Indemnified Party will give prompt written notice, and in any event, no more than fifteen (15) Business Days following such Indemnified Party’s receipt of such claim or demand, to the Indemnifying Party describing in reasonable detail the basis of such claim or demand as to which it may request indemnification hereunder; provided, however, that any such notice need only specify such information to the knowledge of the Indemnified Party as of the date of such notice and shall not limit or prejudice any of the rights or remedies of any Indemnified Party (including pursuant to Section 8.1) on the basis of any such limitations on the information included in such notice or any limitations made in good faith to preserve the attorney-client privilege, work product doctrine or any other privilege, provided, further that the failure to notify or delay in notifying an Indemnifying Party as provided in this sentence or the next sentence will not relieve the Indemnifying Party of its obligations pursuant to Sections 8.2 or 8.3 above, as applicable, except to the extent that such failure actually xxxxx the Indemnifying Party (it being understood that any claim for indemnity pursuant to Sections 8.2(a) or 8.3(a) above must be made by notice given as provided in this sentence or the next sentence within the applicable survival period

specified in Section 8.1 above). Any other claim for indemnification will be made as promptly as practicable after the time the Indemnified Party becomes aware of the facts forming the basis of such claim. The Indemnifying Party will have the right, at its sole expense, to defend and to direct the defense against and management and settlement of any such claim or demand, in its name or in the name of the Indemnified Party, with counsel or other representatives selected by the Indemnifying Party and reasonably acceptable to the Indemnified Party, provided that the Indemnifying Party may not assume the defense, management or settlement of any such claim if (i) such claim seeks injunctive or other equitable relief against the Indemnified Party or (ii) the Indemnified Party has determined in good faith that Losses that may be incurred as a result of such claim, either individually or when aggregated with all other outstanding indemnification claims under this Article VIII, would exceed the amount specified in Section 8.4(a). The Indemnifying Party may not settle or compromise any such claim or demand without the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld, delayed or conditioned) unless the relief consists solely of monetary Losses to be paid by the Indemnifying Party and includes as an unconditional term thereof the giving by the Person asserting such claim to all Indemnified Parties of an unconditional release from all liability with respect to such claim. Each party will cooperate with the other party and make available its officers and employees and relevant files and records (and those of its Affiliates), and agrees to promptly provide such information as to the defense of any such claim or demand as the other party shall reasonably request. The Indemnified Party will have the right to participate in (but not control) the defense of any claim or demand with counsel of its choice employed by it at the expense of the Indemnified Party and will have the right, but not the obligation, to assert any and all cross-claims and counterclaims it may have. In the event the Indemnifying Party does not notify the Indemnified Party within thirty (30) days of the receipt of notice of a Third-Party Claim that it elects to undertake the defense thereof or is not permitted or, shall fail to, defend, contest or otherwise protect against the imposition of any such damages as to any such claim, the Indemnified Party shall have the right, but not the obligation, to defend, contest or assert any cross-claim or counterclaim or otherwise protect against such claim and may make any compromise or settlement thereof and recover from and be indemnified by the Indemnifying Party for the entire reasonable cost thereof, including reasonable fees and disbursements of counsel; provided that the Indemnifying Party will have no indemnification obligations with respect to any such claim or demand which is settled by the Indemnified Party without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld, delayed or conditioned).

8.7 Further Limitations on Indemnification.

(a) Following the Closing, except with respect to matters covered by Section 1.5, the rights of the parties under Sections 8.2 and 8.3 (and under Article IX) will be the exclusive remedy of the parties (and the Transferred Companies) with respect to any claims a party may have against the other party or such other party’s Affiliates under, relating to or in

connection with this Agreement and the transactions contemplated hereby, and except with respect to the matters covered by Section 1.5, or for the obligations of Parent under Section 8.2 (and under Article IX), Parent shall have no liability to Buyer or its Affiliates under, relating to or in connection with this Agreement or the transactions contemplated hereby; provided, however, that nothing in this Section 8.7 limits or modifies any rights of either party to seek

specific performance or specific enforcement of, or other injunctive or equitable relief in respect of, any express provision of this Agreement.

(b) In the event that an Indemnifying Party is obligated to indemnify an Indemnified Party pursuant to this Article VIII, the Indemnifying Party will, upon payment of such indemnity, be subrogated to all rights of the Indemnified Party with respect to claims to which such indemnification relates.

(c) Notwithstanding anything to the contrary herein, (i) other than with respect to the survival of the representations or warranties set forth in Section 2.7, this Article VIII shall have no application with respect to indemnification for Taxes, which shall otherwise be covered exclusively by Sections 9.1 and 9.2 and (ii) nothing in this Article VIII shall limit the rights or remedies of any Person under this Agreement based upon or in connection with fraud, intentional misrepresentation or willful misconduct.

8.8 Tax Treatment of Payments. Any indemnification payment made pursuant to this Article VIII shall be treated for all Tax purposes as an adjustment to the Purchase Price to the extent permitted by applicable Legal Requirements.

ARTICLE IX

TAX AND EMPLOYEE MATTERS

9.1 Certain Tax Matters.

(a) (i) To the extent permitted by applicable Legal Requirements, at the request of Parent, Buyer shall cooperate with Parent in making any elections or taking any other actions that will result in any taxable periods of the Transferred Companies that begin prior to the Closing Date ending on or prior to the Closing Date. Parent, Buyer and their Affiliates shall cooperate and shall make such elections and take such other actions necessary to terminate the Tax year of the U.K. Company as of the Closing Date.

(ii) Parent will cause to be prepared and filed all Income Tax Returns (including any consolidated, unitary or combined Income Tax Returns) required to be filed with respect to any Transferred Company for any taxable period ending on or before the Closing Date (any such period, a “Pre-Closing Period”). Parent shall cause to be delivered to Buyer drafts of any such material Income Tax Returns (other than any Income Tax Returns filed by a combined, unitary or consolidated group with respect to which a Transferred Company is not the parent) at least fifteen (15) Business Days prior to the due date for filing such Income Tax Return for Buyer’s review and comment (which Parent shall not be obligated to accept) within five (5) Business Days after receipt of the drafts from Parent. Parent will include (or cause to be included) the income of Southern Clay Products in the consolidated federal Income Tax Returns filed by Rockwood for all taxable years ending on or before the Closing Date. Buyer will cause to be prepared and filed all Tax Returns other than Income Tax Returns (any such Tax Returns, “Non-Income Tax Returns”) required to be filed with respect to any Transferred Company for any Pre-Closing Period that are due after the Closing; provided, however, that (A) drafts of any such Non-Income Tax Returns (other than monthly returns for

VAT, wage tax and social security) shall be provided to Parent for its review and comment at least thirty (30) days prior to filing and the parties will use all reasonable efforts to resolve any dispute with respect to such Non-Income Tax Returns, but if such dispute cannot be resolved by the parties within fifteen (15) days after Buyer receives notice of such dispute, it shall be referred to the Selected Accountants, (B) such Non-Income Tax Returns shall be prepared in a manner consistent with past practice, except as otherwise required by applicable Legal Requirements and (C) Parent may assume responsibility for preparing and filing any such Non-Income Tax Returns (other than monthly returns for VAT, wage tax and social security) upon notice to Buyer at least thirty (30) days before any such Non-Income Tax Return is due. Neither Buyer nor any of its Affiliates (including, after the Closing, the Transferred Companies) shall amend any Tax Return for a Pre-Closing Period without Parent’s consent (not to be unreasonably withheld, delayed or conditioned).

(iii) Parent will pay, and will indemnify and hold harmless Buyer and its Affiliates from and against, on a Net After-Tax Basis, Taxes imposed upon or incurred by any Transferred Company (A) for any Pre-Closing Period or that relate to the portion of any Straddle Period ending on the Closing Date (including, without limitation, any Taxes for a Pre-Closing Period as a result of the Restructurings or the satisfaction of the Transferred Companies’ Indebtedness pursuant to Section 4.11) or (B) that result from (I) a breach of a representation or warranty in Section 2.7(f), (g), (h), (k), (l), (m), or (n) or a covenant in Section 4.3, (II) secondary liabilities for Taxes under Treasury Regulation § 1502-6 or any comparable provision of state, local or non-U.S. law or of any Transferred Companies having been, on or before the Closing Date, a member of a consolidated, combined or affiliated group for Tax purposes or (III) payment of the Transaction Bonuses described in Section 9.3(h), except in the case of (A) and (B) above, to the extent that the liability for such Taxes was included in the calculation of Closing Working Capital; provided, however, that Buyer will pay, and will indemnify and hold harmless Parent and its Affiliates from and against, on a Net After-Tax Basis, any Taxes imposed as a result of (A) any action outside the ordinary course of business effected by Buyer or its Affiliates (including, after the Closing, the Transferred Companies) on the Closing Date, (B) any Tax election made by Buyer or its Affiliates (including, after the Closing, the Transferred Companies), except for any such election directed by Parent or required pursuant to this Agreement, or (C) the breach by Buyer of any of its covenants hereunder. To the extent that the accrued liability with respect to any such Taxes in the calculation of Closing Working Capital exceeds the actual liability, Buyer shall cause the Transferred Companies to pay such excess to Parent within fifteen (15) days after filing the relevant Tax Return for such Pre-Closing Period or Straddle Period, as the case may be. Notwithstanding anything to the contrary in this Section 9.1(a)(iii), Parent shall have no liability pursuant to this Section 9.1(a)(iii) for any Tax to the extent a reserve for such Tax is included or taken into account in the calculation or determination of Transferred Company Indebtedness.

(b) (i) (A) Buyer will cause to be prepared and filed all Tax Returns required to be filed by or on behalf of any Transferred Company for any taxable period beginning before and ending after the Closing Date (any such period, a “Straddle Period”); provided, however, that drafts of any such Tax Return (other than a monthly return for VAT, wage tax and social security) shall be provided to Parent for its review and comment at least thirty (30) days prior to filing, and such Tax Returns shall be subject to Parent’s review and

approval. To the extent that any dispute with respect to the preparation of a Straddle Period Tax Return cannot be resolved by the parties at least fifteen (15) days prior to the due date of the Tax Return, it shall be referred to the Selected Accountants for resolution. Except as otherwise consented to by Parent or as required by applicable Legal Requirements, any such Tax Returns will be prepared on a basis consistent with past practices of the Transferred Companies.

(ii) In the case of any Taxes that are payable for a Straddle Period, the portion of such Tax which relates to the portion of such Straddle Period ending on the Closing Date shall (A) in the case of any Taxes in the nature of property Taxes, be deemed to be equal to the amount of such Tax for the entire tax period multiplied by a fraction, the numerator of which is the number of days in the portion of the Straddle Period ending on the Closing Date and the denominator of which is the number of days in the entire Straddle Period and (B) in the case of any Taxes other than Taxes in the nature of property Taxes, be equal to the amount which would be payable if the relevant Tax period ended on the Closing Date assuming a deemed closing of the books, except that exemptions, allowances and deductions (such as depreciation deductions) calculated on an annual basis shall be prorated between the portion of the applicable Straddle Period that ends on the Closing Date and the portion after the Closing Date on a per diem basis.

(iii) Subject to Section 9.1(a)(iii), Buyer shall reimburse Parent, and will indemnify and hold harmless Parent and its Affiliates from and against, on a Net After-Tax Basis from any Taxes imposed upon Parent or its Affiliates for any Taxes, attributable to the Post-Closing portion of any Straddle Period, except to the extent such Taxes are imposed as a result of any breach by Parent of any of its covenants hereunder. Any Taxes (including estimated Taxes) paid by the Transferred Companies with respect to any Straddle Period prior to the Closing shall be credited against Parent’s liability pursuant to Section 9.1(a)(iii). Neither Buyer nor any of its Affiliates (including, after the Closing, the Transferred Companies) shall amend any Tax Return for a Straddle Period without Parent’s written consent (not to be unreasonably withheld, delayed or conditioned).

(c) Buyer shall be responsible for, and shall indemnify and hold harmless Parent and its Affiliates from and against, on a Net After-Tax Basis, any Taxes of the Transferred Companies for taxable periods beginning after the Closing Date, except to the extent that such Taxes are imposed as a result of the breach by Parent of any of its covenants under this Agreement.

(d) Parent or, respectively, Buyer will be entitled to retain, or receive prompt payment from Buyer or, respectively, Parent of, to the extent not included in the calculation of Closing Working Capital, any refund or credit for overpayment of Taxes for which Parent or, respectively, Buyer (including by way of offset) is responsible pursuant to Sections 9.1(a) or (b) plus any interest received with respect thereto from the relevant taxing authorities. Buyer will, if Parent so reasonably requests in good faith and at Parent’s expense, cause the Transferred Companies to promptly file for and obtain any refunds or credits to which Parent is entitled under this Section 9.1(d); provided that such claim for refund or credit would not reasonably be expected to have a material adverse effect on Buyer after the Closing Date. Buyer will permit Parent to control (at Parent’s expense) the prosecution of any such claim for refund

and, when deemed appropriate by Parent, will cause the relevant Entity to authorize by appropriate power of attorney such person as Parent may designate to represent such Entity with respect to such refund claimed. For purposes of this Section 9.1(d), a party will be deemed to have made prompt payment of a refund or credit if such payment is made within ten (15) days of the receipt by such party of such refund or of the use by such party of such credit.

(e) If and to the extent that any audit or other adjustment to a Tax Return filed by or on behalf of a Transferred Company for a Pre-Closing Period results not only in an increase in Tax liability for which Parent is responsible pursuant to Section 9.1(a) or (b) (including, without limitation, any liability with respect to a consolidated, combined or unitary Tax) but also in a corresponding Tax benefit to Buyer (or any of its Affiliates, including the Transferred Companies) for any taxable period or portion thereof following the Closing (including, without limitation, as a result of income having been accelerated from a period following the Closing to a Pre-Closing period, deductions or credits being deferred from a Pre-Closing Period to a period following the Closing, or increased depreciation or amortization deductions being allowed following the Closing), within thirty (30) days following such adjustment, Buyer shall pay over to Parent an amount equal to the net present value of any such corresponding Tax benefit (less any related costs) to Buyer (or any of its Affiliates) up to, but not in excess of, the corresponding Tax liability, it being understood that the net present value of a Tax benefit shall be calculated based on the relevant applicable Tax rate and using a 5.5% annual discount rate.

(f) Buyer will promptly notify Parent in writing upon receipt by Buyer or any of its Affiliates (including, after the Closing, the Transferred Companies) of notice of any pending or threatened audit or assessment with respect to Taxes for which Parent would be required to pay or indemnify Buyer or any of its Affiliates pursuant to Sections 9.1(a) or (b) (each an “Indemnifiable Tax Claim”); provided that the failure to so notify shall not relieve the Parent of its obligations under Sections 9.1(a) or (b), except to the extent (and only to the extent) that Parent is actually prejudiced thereby. Except as otherwise required by applicable Legal Requirements, Parent shall have thirty (30) days after receipt of such notice to assume the conduct and control, through counsel reasonably acceptable to Buyer at the expense of Parent, of the defense of the Indemnifiable Tax Claim, and Buyer shall cooperate with Parent in connection therewith; provided that Parent shall not, except with the consent of Buyer (which consent shall not be unreasonably withheld, delayed or conditioned), compromise or settle any such proceeding, or provide any consents or waivers to extend applicable statutes of limitations. If Parent shall assume the conduct and control of any Indemnifiable Tax Claim, Parent shall permit Buyer to participate, at Buyer’s own expense, in such defense (including, for the avoidance of doubt, by permitting reasonable opportunity for Buyer to review and comment upon any proposed representations to be made, or caused to be made, by Parent in respect of an Indemnifiable Tax Claim) through counsel chosen by Buyer (and the fees and expenses of such counsel shall be borne by Buyer). So long as Parent is reasonably so contesting the Indemnifiable Tax Claim in good faith, Buyer shall not, and shall not permit any Transferred Company to, pay or settle the Indemnifiable Tax Claim; provided that, notwithstanding the foregoing, Buyer shall have the right to pay or settle, or cause to be paid or settled, the Indemnifiable Tax Claim if Buyer waives its right to indemnification with respect to such Indemnifiable Tax Claim and Parent shall have consented to such payment or settlement (such

consent not to be unreasonably withheld, conditioned or delayed). If Parent does not notify Buyer within thirty (30) days after the receipt of the Buyer’s notice of an Indemnifiable Tax Claim that it elects to undertake the defense thereof, Buyer shall have the right to contest, settle or compromise the Indemnifiable Tax Claim but shall not thereby waive any right to indemnity therefor pursuant to this Agreement, and Buyer shall be entitled to reimbursement of any reasonable costs and expenses (including reasonable attorney fees and disbursements of counsel) with respect thereto. Buyer and Parent shall, at their own expense, jointly control any audit, examination, administrative or court proceeding in respect of Taxes related to any Straddle Period.

(g) After the Closing Date, each of Buyer and Parent will (at its own expense) provide the other with such assistance as may reasonably be requested by the other party in connection with the preparation of any return, report, or form with respect to Taxes or any audit or administrative or judicial proceeding (such assistance to include assistance in data collection and responses to information requests) relating to liability for Taxes of the Transferred Companies or any affiliated, consolidated, combined or unitary group in which any of the Transferred Companies is included.

(h) Buyer will be responsible for payment of, and will indemnify and hold Parent and its Affiliates harmless from and against all documentary, stamp, transfer, sales, use, excise and similar Taxes imposed upon Parent or Buyer or their respective Affiliates (including the Transferred Companies) in connection with this Agreement and the transactions contemplated hereby; provided, for the avoidance of doubt, that Parent shall be responsible for any Taxes arising in connection with the Restructurings. Buyer will be responsible for preparing and timely filing any forms required with respect to any such Taxes. Promptly following the filing of each such return, Buyer will provide to Parent a true copy of such return as filed and evidence of the timely filing thereof and a receipt showing payment of any Taxes owed.

(i) Subject to Section 4.22, any Tax sharing agreement or arrangement between or among Parent or any of its Affiliates (other than the Transferred Companies), on the one hand, and the Transferred Companies, on the other hand, shall be terminated or cancelled, and Parent and its Affiliates shall take such additional steps as may be required so that, in each case, as of the Closing Date any such agreement or arrangement shall have no further effect for any taxable year (whether the current year, a future year or a past year), and after the Closing Date none of Parent or any of its Affiliates (other than Transferred Companies) shall make any claim against any Transferred Company in respect of such an agreement or arrangement.

(j) Any amount paid by or on behalf of any party to or on behalf of another party pursuant to this Section 9.1 shall be treated for all Tax purposes as an adjustment to the Purchase Price to the extent permitted by applicable Legal Requirements.

(k) Parent shall be subrogated to any rights (including rights to indemnification) that Buyer or its Affiliates (including the Transferred Companies) may have against third parties (other than employees and managers of the Transferred Companies) with respect to Taxes paid or indemnified by Parent pursuant to this Section 9.1, so long as such rights are exercised in a commercially reasonable manner.

(l) The indemnification obligations in this Section 9.1 shall survive until the date that is (x) thirty (30) days following the expiration of the applicable statute of limitations in the case of any Taxes other than German Taxes, and (y) six (6) months after the Tax assessment becomes binding and unappealable (formell und materiell bestandskraftige) in the case of German Taxes.

9.2 Certain VAT Matters.

(a) Buyer and Parent are of the opinion that the transactions contemplated by this Agreement are not subject to VAT and Buyer and Parent agree not to take, or cause to be taken, any action that could reasonably be expected to cause VAT to become due. Parent shall, and shall procure that the other Sellers undertake, not to opt to treat the transactions contemplated hereunder as being subject to VAT (or other Tax of a similar nature in any jurisdiction). To the extent that the transactions contemplated in this Agreement are confirmed by an applicable Governmental Authority to be subject to VAT (or any other Tax of a similar nature in any jurisdiction), Buyer shall pay, and shall indemnify and hold harmless Parent, Sellers and each of their Affiliates from, such VAT (or any other tax of a similar nature in any jurisdiction), in addition to the Purchase Price, except to the extent that such VAT (or any other tax of a similar nature in any jurisdiction) is triggered by actions of Sellers which actions are not contemplated by this Agreement. To the extent so required, VAT (or any other tax of a similar nature in any jurisdiction) shall be payable by Buyer immediately upon receipt from the Sellers an invoice which complies with the respective VAT provisions of the respective VAT Code or other applicable Legal Requirement.

(b) With respect to the VAT fiscal unity (umsatzsteuerliche Organschaft) between RSGG as the common parent company (Organträger) and Xxxxxxxx Xxxx Additives as controlled entity (Organgesellschaft) (the (“Controlled VAT Member”), (i) the Controlled VAT Member shall, and the Buyer shall procure that the Controlled VAT Member will, reimburse RSGG for any output VAT (Umsatzsteuer), which relates to supplies rendered or advance payments received by such Controlled VAT Member until and including the Closing Date and is paid or otherwise settled by RSGG in its capacity as the common parent, and (ii) RSGG shall reimburse the Controlled VAT Member for any input VAT (Vorsteuer), which relates to supplies or advanced payments received by the Controlled VAT Member until and including the Closing Date and is credited to RSGG in its capacity as the common parent.

(c) The Controlled VAT Member shall not be required to reimburse RSGG pursuant to Section 9.2(b)(i), and RSGG shall not be required to reimburse the Controlled VAT Member pursuant to Section 9.2(b)(ii) if, and to the extent that, the Controlled VAT Member effected payment of the respective output VAT amount to RSGG or received payment of the respective input VAT amount from RSGG, as the case may be, on or prior to the Closing Date. Moreover, the Controlled VAT Member shall not be required to reimburse RSGG, and RSGG shall not be required to compensate the Controlled VAT Member, as the case may be, with respect to any amounts that were not reflected as a liability or asset in the calculation of Closing Working Capital or as Transferred Company Indebtedness. RSGG and the Controlled VAT Member shall, and Buyer shall procure that the Controlled VAT Member will reasonably

cooperate to reduce the financial burden from such amounts, in particular if, and to the extent that such reduction does not result in any material cost to Buyer or the Controlled VAT Member.

(d) For the avoidance of doubt, this Section 9.2 relates solely to those VAT matters referred to herein and the provisions of Section 9.1 shall control with respect to all other Tax matters.

9.3 U.S. Employee Matters.

(a) From and after the Closing Date until the twelve (12) month anniversary thereof, Buyer shall, or shall cause Southern Clay Products to, provide (other than with respect to any U.S. Business Employees who are represented by a collective bargaining agreement) (i) a base salary or base wages to each U.S. Business Employee whose employment continues following the Closing (each a “Continuing U.S. Employee”) at an annual rate that is no less than the annual rate of the base salary or base wages that was provided to such employee immediately prior to the Closing Date and (ii) employee benefits to the Continuing U.S. Employees that are substantially equivalent in the aggregate to either (A) the employee benefits provided to such employees immediately prior to the Closing Date or (B) to similarly situated employees of Buyer or its Affiliates, disregarding (except as contemplated by the terms of this Agreement) any, equity or equity-based compensation, Transaction Bonuses or change of control arrangements. Effective as of the Closing, Buyer shall, and shall cause Southern Clay Products to, honor the terms of any collective bargaining agreement and union shutdown agreement covering any of the Continuing U.S. Employees and to continue to provide any compensation or employee benefits required to be provided under the terms of any such agreements. With respect to those Continuing U.S. Employees whose services are performed pursuant to an employment agreement, effective as of the Closing, Buyer shall, and shall cause Southern Clay Products to, honor the terms of such employment agreement.

(b) Buyer shall ensure that, at all times following the Closing, each Continuing U.S. Employee receives full credit for purposes of eligibility, vesting and benefit accruals (solely, in the case of benefit accruals, for purposes of determining vacation and severance) for all service that was recognized by Southern Clay Products or any of its Affiliates under Benefit Plans with respect to such employee under each of the comparable employee benefit plans, programs or policies of Buyer or its Affiliates (including Southern Clay Products) in which such employee becomes or may become a participant, provided that no such service recognition shall result in any duplication of benefits.

(c) Effective as of the Closing, Southern Clay Products shall withdraw from participation in all Benefit Plans other than U.S. Transferred Company Benefit Plans, and Buyer and its Affiliates (including Southern Clay Products), shall continue to be responsible for any U.S. Transferred Company Benefit Plans.

(d) Buyer shall, or shall cause Southern Clay Products to, provide severance pay and benefit entitlements to any Continuing U.S. Employee whose employment is terminated by Buyer or any of its Affiliates (including Southern Clay Products), other than for cause, within twelve (12) months after the Closing Date, in an amount no less favorable than

either (i) the amount of severance pay and benefit entitlements, if any, determined in accordance with the severance policy or agreement applicable to such Continuing U.S. Employee as in effect immediately prior to the Closing or (ii) the amount of severance pay and benefit entitlements, if any, to which similarly situated employees of Buyer or its Affiliates would be entitled.

(e) Effective as of the Closing, Buyer shall (i) establish or maintain, or cause to be established or maintained, one or more group health plans which shall cover all Continuing U.S. Employees and dependents who immediately prior to the Closing were covered under any group health plan maintained by Parent or any of its Affiliates, (ii) waive any waiting period and any exclusion or limitation for preexisting conditions which were covered under the health plan maintained by Parent or any of its Affiliates in which the Continuing U.S. Employee and any eligible dependents participated immediately prior to the Closing to the same extent recognized by Parent or any of its Affiliates immediately Closing and (iii) grant credit (for purposes of annual deductibles, co-payments and out-of-pocket limits) for any covered claims incurred or payments made prior to the Closing Date during the plan year in which the Closing Date occurs.

(f) (i) Buyer shall take all steps necessary to permit each Continuing U.S. Employee who has received an eligible rollover distribution (as defined in Section 402(c)(4) of the Code) from the Rockwood Retirement Plan to roll over such eligible rollover distribution as part of any lump sum cash distribution into an account(s) under a 401(k) plan maintained by Buyer or its Affiliates (the “Buyer 401(k) Plan”).

(ii) With respect to each Continuing U.S. Employee who is a participant in the Rockwood Retirement Plan on the Closing Date and who continues in employment with Buyer or any of its Affiliates (including Southern Clay Products) through December 31, 2013:

(A) Parent shall pay to Buyer an amount equal to the product of (x) the “covered compensation” under the Rockwood Retirement Plan earned by such Continuing U.S. Employee from the beginning of the Rockwood Retirement Plan’s 2013 plan year through the Closing Date and (y) the “Applicable Percentage.” The Applicable Percentage shall mean the profit sharing contribution percentage up to a maximum of 4% of a Continuing U.S. Employee’s “covered compensation,” as determined by Parent it its sole discretion, that would have been made by Parent with respect to the Continuing U.S. Employee for the Rockwood Retirement Plan’s 2013 plan year if the Continuing U.S. Employee had remained in “eligible employment” under the Rockwood Retirement Plan through the end of the 2013 plan year. The aggregate amount, if any, payable with respect to the Continuing U.S. Employees pursuant to this Section 9.3(f)(ii)(A) (the “Parent PSP Contribution”) shall be paid to Buyer as soon as practicable (but not more than thirty (30) days) after the date that Parent determines to make a profit sharing contribution under the Rockwood Retirement Plan with respect to the 2013 plan year. Each Continuing U.S. Employee’s allocable share of the Parent PSP Contribution shall be credited by Buyer to the Continuing U.S. Employee under the Buyer 401(k) Plan.

(B) Parent shall pay to Buyer an amount equal to the product of (x) the “covered compensation” under the Rockwood Retirement Plan earned by such Continuing U.S. Employee from the beginning of the Rockwood Retirement Plans’ 2013 plan year through the Closing Date and (y) 3%. The aggregate amount payable with respect to the Continuing U.S. Employees pursuant to this Section 9.3(f)(ii)(B) (the “Parent Nonelective Contribution”) shall be paid to Buyer as soon as practicable (but not more than thirty (30) days) after Parent makes nonelective contributions under the Rockwood Retirement Plan with respect to the 2013 plan year. Each Continuing U.S. Employee’s allocable share of the Parent Nonelective Contribution shall be credited by Buyer to the Continuing U.S. Employee under the Buyer 401(k) Plan.

(iii) For the avoidance of doubt, neither the Parent PSP Contribution nor the Parent Nonelective Contribution, nor any assets or liabilities associated therewith, shall be reflected in the Final Closing Statement or be taken into account in the calculation of Closing Working Capital.

(g) Following the Closing, Buyer shall (i) pay to the Continuing U.S. Employees such amounts with respect to the Parent’s or any of its Affiliate’s (including the Transferred Companies’) bonus plans for the 2013 bonus plan year (the “Bonus Plans”) as are reflected in the calculation of Closing Working Capital and taken into account in the calculation of the Final Closing Statement and (ii) provide each Continuing U.S. Employee with an opportunity to earn bonus compensation amounts with respect to the balance of the 2013 bonus plan year immediately following the Closing Date, that are no less favorable than the bonus compensation amounts that each such Continuing U.S. Employee had the opportunity to earn under the Bonus Plans immediately prior to the Closing. Any amounts payable by Buyer pursuant to this Section 9.3(g) shall be subject to the same terms and conditions as would have applied, and paid at such times and in such manner as such amounts would have been payable, under the Bonus Plans.

(h) Parent shall pay or cause to be paid the full amount that may become due or payable under, taking into account any forfeiture or cancellation in accordance with the terms of, any transaction or retention incentives, bonuses or awards made as a result or in connection with the transactions contemplated by this Agreement (the “Transaction Bonuses”) to Business Employees and directors of the Transferred Companies.

(i) Upon reasonable request, Parent shall provide to Buyer, and Buyer shall provide to Parent, such documents, data and information as may reasonably be necessary to implement the provisions of this Section 9.3 and to administer their respective benefit plans.

(j) Nothing contained herein, expressed or implied, (i) shall confer upon any of the employees of Parent, Buyer, the Transferred Companies or any of their Affiliates, any rights or remedies, including any right to benefits or employment, or continued benefits or employment, for any specified period, of any nature or kind whatsoever by reason of this Agreement, or (ii) shall be construed to establish, amend or modify any benefit plan, program, agreement or arrangement. This shall not prevent the parties entitled to enforce this Agreement from enforcing any provision in this Agreement, but no other party shall be entitled

to enforce any provision in this Agreement on the grounds that it is an amendment to such benefit plan, program, agreement or arrangement. If a party not entitled to enforce this Agreement brings a lawsuit or other action to enforce any provision in this Agreement as an amendment to such benefit plan, program, agreement or arrangement and that provision is construed to be such an amendment despite not being explicitly designated as one in this Agreement, that provision shall lapse retroactively as of its inception, thereby precluding it from having any amendatory effect.

9.4 Non-U.S. Employee Benefit Plan Matters.

(a) Xxxxxxxx Xxxx Additives is a member of, and the parties understand that it will be able to continue its membership in, the pension fund Pensionskasse für die deutsche Wirtschaft e.V. after the Closing.

(b) Parent shall cause the individuals set forth on Schedule 9.4(b) of the Disclosure Letter (“Remote Employees”), to cease to be employed by Parent or its Affiliates, effective as of the Closing, and Buyer shall (or shall cause its Subsidiaries to) make an offer of employment, effective as of the Closing, to each Remote Employee.

(c) Upon reasonable request, Parent shall provide to Buyer, and Buyer shall provide to Parent, such documents, data and information as may reasonably be necessary to implement the provisions of this Section 9.4 and to administer their respective benefit plans.

(d) Nothing contained herein, expressed or implied, (i) shall confer upon any of the employees of Parent, Buyer, the Transferred Companies or any of their Affiliates, any rights or remedies, including any right to benefits or employment, or continued benefits or employment, for any specified period, of any nature or kind whatsoever by reason of this Agreement, or (ii) shall be construed to establish, amend or modify any benefit plan, program, agreement or arrangement. This shall not prevent the parties entitled to enforce this Agreement from enforcing any provision in this Agreement, but no other party shall be entitled to enforce any provision in this Agreement on the grounds that it is an amendment to such benefit plan, program, agreement or arrangement. If a party not entitled to enforce this Agreement brings a lawsuit or other action to enforce any provision in this Agreement as an amendment to such benefit plan, program, agreement or arrangement and that provision is construed to be such an amendment despite not being explicitly designated as one in this Agreement, that provision shall lapse retroactively as of its inception, thereby precluding it from having any amendatory effect.

10.6 Amendment; Waiver. This Agreement may only be amended or modified in writing signed by the party against whom enforcement of any such amendment or modification is sought. No breach of any covenant, agreement, representation or warranty made herein shall be deemed waived unless expressly waived in writing by the party who might assert such breach.

10.8 Governing Law; Consent to Jurisdiction; Waiver of Jury Trial.

(a) This Agreement shall be governed by the laws of the State of New York, without regard to any conflicts of law rules or principles that would result in the application of the laws of another jurisdiction.

(b) Each party hereto hereby consents to, and confers exclusive jurisdiction upon, the courts of the State of New York and the Federal courts of the United States of America located in the County of New York in the State of New York, and appropriate appellate courts therefrom, over any action, suit or proceeding arising out of or relating to this Agreement or any Ancillary Document. Each party hereto hereby waives, and agrees not to assert, as a defense in any such action, suit or proceeding that it is not subject to such jurisdiction or that such action, suit or proceeding may not be brought or is not maintainable in said courts or that this Agreement or any Ancillary Document may not be enforced in or by said courts or that its Assets are exempt or immune from execution, that such action, suit or proceeding is brought in an inconvenient forum, or that the venue of such action, suit or proceeding is improper. Parent and Buyer covenant not to initiate any such action, suit or proceeding in any other jurisdiction. Service of process in any such action, suit or proceeding may be served on any party anywhere in the world, whether within or without the State of New York, as provided in Section 10.3 herein.

(c) Each party hereby waives to the fullest extent permitted by applicable Legal Requirements, any right it may have to a trial by jury in respect of any proceeding directly or indirectly arising out of, under or in connection with this Agreement or any Ancillary Document or any transaction contemplated hereby or thereby. Each party (i) certifies that no representative, agent or attorney of any other party has represented, expressly or otherwise, that such other party would not, in the event of litigation, seek to enforce the foregoing waiver and (ii) acknowledges that it and the other parties hereto have been induced to enter into this Agreement by, among other things, the mutual waivers and certifications in this paragraph.

10.9 Specific Performance. The parties hereto recognize that any breach of the terms of this Agreement may give rise to irreparable harm for which money damages would not be an adequate remedy, and accordingly agree that, in addition to all other remedies available to it, any nonbreaching party shall be entitled to seek to enforce the terms of this Agreement by a decree of specific performance, without the necessity of proving the inadequacy as a remedy of money damages.

10.10 Interpretation; Absence of Presumption.

(a) For the purposes of this Agreement, (i) words in the singular shall be held to include the plural and vice versa, (ii) the terms “hereof,” “herein,” and “herewith” and words of similar import shall, unless otherwise stated, be construed to refer to this Agreement as a whole (including all of the Schedules and Exhibits hereto and the Disclosure Letter) and not to

any particular provision of this Agreement, and Article, Section, Exhibit and Schedule references are to the Articles, Sections, Exhibits, and Schedules to this Agreement or the Disclosure Letter unless otherwise specified, (iii) except where the context otherwise requires, references to a “party” or “parties” shall mean Buyer or Parent, or both of them as the context requires, (iv) the word “including” and words of similar import when used in this Agreement shall mean “including, without limitation,” unless the context otherwise requires or unless otherwise specified, (v) the word “or” shall not be exclusive, (vi) the word “extent” in the phrase “to the extent” shall mean the degree to which a subject or thing extends, and such phrase shall not mean simply “if”, (vii) unless a contrary intent is apparent, any contract, instrument or Legal Requirement defined or referred to herein means such contract, instrument or Legal Requirement as from time to time amended, modified or supplemented, including by succession of comparable successor Legal Requirement, (viii) except as otherwise set forth in this Agreement, any accounting terms shall be given their definition under GAAP, (ix) the phrase “ordinary course of business” shall mean “ordinary course of business consistent with past practice” and (x) any document or information shall be deemed to have been “made available” only if such document or information was posted to the electronic dataroom created for the purpose of aiding in Buyer’s diligence investigation or otherwise delivered to Buyer on or before the date that is prior to the date hereof.

(b) With regard to each and every term and condition of this Agreement and any and all agreements and instruments subject to the terms hereof, the parties understand and agree that the same have or has been mutually negotiated, prepared and drafted, and if at any time the parties hereto desire or are required to interpret or construe any such term or condition or any agreement or instrument subject hereto, no consideration will be given to the issue of which party actually prepared, drafted or requested any term or condition of this Agreement or any agreement or instrument subject hereto.

10.11 Third Person Beneficiaries. This Agreement is not intended to confer upon any other Person any rights or remedies hereunder. Each of Buyer and Parent may assert the rights of Buyer Indemnitees and Seller Indemnitees, respectively, pursuant to Article VIII hereof.

10.12 Representations and Warranties; Schedules. Neither the specification of any dollar amount in the representations and warranties set forth in Article II nor the indemnification provisions of Article VIII nor the inclusion of any items in any Schedule of the Disclosure Letter will be deemed to constitute an admission by Parent or Buyer, or otherwise imply or create any presumption, that any such amounts or the items so included are material for the purposes of this Agreement, or that any such item meets any or all of the criteria set forth in this Agreement for inclusion in such Schedule to the Disclosure Letter or any other Schedule to the Disclosure Letter. It is understood and agreed that nothing in the Disclosure Letter is intended to broaden the scope of any representation or warranty of Parent set forth in Article II of this Agreement. Disclosure of any fact or item in any Schedule of the Disclosure Letter will be deemed to be disclosed only with respect to the Section of this Agreement to which such Schedule corresponds and to any other Schedule of the Disclosure Letter to the extent the relevance of such disclosure to such other Schedule of the Disclosure Letter is reasonably apparent on the face of such disclosure. Any capitalized terms used in the Disclosure Letter or

any Schedule hereto or thereto but not otherwise defined therein shall be defined as set forth in this Agreement.

10.13 Severability. Except as provided in Section 4.15(e), if any one or more of the provisions of this Agreement is held to be invalid, illegal or unenforceable, the validity, legality or enforceability of the remaining provisions of this Agreement will not be affected thereby, and Parent and Buyer will use their reasonable efforts to substitute one or more valid, legal and enforceable provisions which insofar as practicable implement the purposes and intent hereof. To the extent permitted by applicable Legal Requirements, each party waives any provision of applicable Legal Requirements which renders any provision of this Agreement invalid, illegal or unenforceable in any respect.

10.14 Guaranty. Guarantor irrevocably guarantees each obligation of Buyer, and the full and timely performance by Buyer of its obligations, in each case, under the provisions of this Agreement and the Ancillary Documents. This is a guarantee of payment and performance, and Guarantor acknowledges and agrees that this guarantee is full and unconditional, and no release or extinguishment of Buyer’s liabilities and obligations (other than in accordance with the terms of this Agreement or the Ancillary Documents, as applicable), whether by decree in any bankruptcy proceeding or otherwise, will affect the continuing validity and enforceability of this guarantee. Guarantor hereby waives, for the benefit of Parent, (i) any right to require Parent, as a condition of payment or performance of Guarantor, to proceed against Buyer or pursue any other remedies whatsoever and (ii) to the fullest extent permitted by Legal Requirements, any defenses or benefits that may be derived from or afforded by Legal Requirements that limit the liability of or exonerate guarantors or sureties, except to the extent that any such defense is available to Buyer under this Agreement. Guarantor understands that Parent is relying on this guarantee in entering into this Agreement.
