The Closing Date Balance Sheet shall be accompanied by a certificate executed by a senior financial officer of Purchasers’ Representative to the effect that to his actual knowledge the Closing Date Balance Sheet and the calculation of the Closing Date Working Capital and Closing Date Indebtedness have been prepared in good faith in accordance with this Section 2.6(b). The Purchasers shall also provide to the Sellers’ Representative copies of all work papers and other documents and data used to prepare the Closing Date Balance Sheet and to determine the Closing Date Working Capital and Closing Date Indebtedness. The Sellers’ Representative shall have the right (i) to dispute the Closing Date Balance Sheet (and any items therein) and the Closing Date Working Capital and Closing Date Indebtedness calculation and (ii) to make any proposed adjustments thereto as provided in Section 2.6(c).

(i) The Sellers’ Representative shall have until 30 days after the delivery of the calculations and certificates described in Section 2.6(b) to review such calculations and certificates, dispute any items therein and propose any adjustments thereto; provided that such 30-day period shall be extended by any period of time that the Sellers’ Representative is not provided with the access described in Section 2.6(b). If no adjustments are proposed by 5:00 P.M. (New York time) on such 30th day (or such other day as extended pursuant to the preceding sentence), the calculations made by the Purchasers’ Representative, as described in Section 2.6(b), shall be final and binding upon the Rockwood Sellers and the Purchasers at 5:00 P.M. (New York time) on such 30th day (or such other day as extended pursuant to the preceding sentence).

In the event that the Purchasers’ Representative and the Sellers’ Representative cannot agree on a replacement Independent Accountant within five Business Days after being notified that PricewaterhouseCoopers LLP is unable or unwilling to serve, the Purchasers’ Representative and the Sellers’ Representative shall each appoint an internationally recognized independent accounting firm and such appointed accounting firms shall appoint another internationally recognized independent accounting firm to serve as the Independent Accountant. If the Independent Accountant is retained, then the Sellers’ Representative and the Purchasers’ Representative shall each submit to the Independent Accountant in writing, not later than 15 days after the Independent Accountant is retained, their respective positions with respect to the Contested Adjustments, together with such supporting documentation as they deem necessary or as the Independent Accountant requests. The Purchasers’ Representative and the Sellers’ Representative shall instruct the Independent Accountant not to review or take into account any information that is not submitted within such 15-day deadline and to make a determination only as to the Contested Adjustments and not any other items on the Closing Date Balance Sheet. The Purchasers’ Representative and the Sellers’ Representative shall instruct the Independent Accountant to, within 30 days after receiving the positions of the Sellers’ Representative and the Purchasers’ Representative and all supplementary supporting documentation requested by the Independent Accountant, render its decision as to the Contested Adjustments, which decision shall not be greater than the highest position of the parties nor lower than the lowest position of the parties and shall (absent manifest error) be final and binding on, and nonappealable by, the Sellers and the Purchasers. The decision of the Independent Accountant shall also include a certificate of the Independent Accountant setting forth the final calculation in question (the “Settlement Amount Certificate”) and shall be made in a manner consistent with this Section 2.6. Judgment may be entered upon the determination of the Independent Accountant in any court having jurisdiction over the party against which such determination is to be enforced. The Closing Date Working Capital and Closing Date Indebtedness shall be deemed to include all proposed adjustments not disputed by the Purchasers’ Representative and those adjustments accepted or made by the decision of the Independent Accountant in resolving the Contested Adjustments. The fees and expenses of the Independent Accountant shall be paid by the party whose position of the Contested Adjustment is furthest from the Independent Accountant’s calculations of the Contested Adjustment (the “Responsible Party”). In the event that any amount due to the Independent Accountant under this Section 2.6(c) is paid by a party other than the Responsible Party, the Responsible Party shall pay interest on such amount payable to such other party at a rate of six percent (6%) per annum, based on a 360-day year, which shall accrue from the date the other party pays the Independent Accountant to the date of actual payment.

under Section 501(c)(9) of the Internal Revenue Code of 1986, as amended, and the rules and regulations thereunder (the “Code”), profit-sharing, pension, or retirement, deferred compensation, medical, life insurance, disability, accident, salary continuation, severance, vacation, sick pay, sick leave, supplemental retirement and unemployment benefit plans, programs, arrangements, commitments or practices (whether or not insured) and (iii) employment, consulting, termination, and severance contracts or agreements that are not based on a standard form of contract or agreement; currently covering active, retired or former employees or directors of the Target Companies, whether or not any such plans, programs, arrangements, commitments, contracts, agreements or practices (referred to in (i), (ii) or (iii) above) are in writing or are otherwise exempt from the provisions of ERISA, that are maintained or contributed to (or with respect to which an obligation to contribute has been undertaken) or with respect to which any potential liability is borne by Rockwood Specialties or its Affiliates (“Benefit Plans”). The Benefit Plans covering solely active, retired or former employees of the Target Companies are denoted by asterisk on Schedule 3.14(a) of the Seller Disclosure Letter. The asterisked Benefit Plans, excluding the AlphaGary Corporation Union Employees Pension Plan (which will be transferred to Rockwood Specialties or one of its Affiliates (other than a Target Company) prior to Closing in accordance with Section 10.1(d)), are hereinafter referred to as the “Target Company Benefit Plans”. For the avoidance of doubt, the Benefit Plans shall not include any statutory foreign plans with respect to which any Target Company, Rockwood Specialties or any of their Affiliates are obligated to make contributions or comply with under applicable Legal Requirements.

(b) Each Benefit Plan (including any related trust) complies in form with the requirements of all applicable Legal Requirements, including ERISA, the Code, and applicable foreign tax laws, and has at all times been maintained and operated in compliance with its terms and the requirements of all applicable Legal Requirements, including ERISA and the Code, with such exceptions as could not, individually or in the aggregate, result in a material liability of any Target Company. Each Benefit Plan intended to be qualified under Section 401(a) of the Code has received a favorable determination letter from the IRS and each trust established in connection with any Benefit Plan, which is intended to be exempt from U.S. federal income taxation under Section 501(a) of the Code has been determined to be so exempt by the IRS. Since the date of each most recent determination letter, to the Knowledge of Rockwood Specialties, no event has occurred and no condition or circumstance has existed that has resulted, or is likely to result, in the revocation of any such determination letter or that could adversely affect the qualified status of any such Benefit Plan or the exempt status of any such trust, with such exceptions as could not, individually or in the aggregate, result in a material liability of any Target Company. No complete or partial termination of any Benefit Plan has occurred, or to the Knowledge of Rockwood Specialties is expected to occur, and to the Knowledge of Rockwood Specialties no Proceedings have been instituted, and no condition exists and no event has occurred that could constitute grounds, under Title IV of ERISA to terminate, or appoint a trustee to administer, any Benefit Plan, with such exceptions as could not, individually or in the aggregate, result in a material liability of any Target Company. None of the Rockwood Sellers nor the Target Companies has any commitment, intention or understanding to create, materially modify or terminate any Target Company Benefit Plan, other than as required by applicable Legal Requirements, the terms of any Material Contract, or the terms of any Target Company Benefit Plan. Except as required to maintain the tax-qualified status of any Benefit Plan intended to qualify under Section 401(a) of the Code, no condition or circumstance exists that would

prevent the amendment or termination of any Target Company Benefit Plan. No event has occurred, and no condition or circumstance has existed, that could result in a material increase in the benefits under, or the expense of maintaining (as a result of a plan amendment, written interpretation or announcement issued by a Governmental Body), any Target Company Benefit Plan from the level of benefits thereunder or expense incurred thereof for the most recent fiscal year ended. No Target Company Benefit Plan is a plan described in Section 4063(a) of ERISA. No Target Company Benefit Plan has assets that include securities issued by any Rockwood Seller or any Target Company. As of the date of this Agreement, neither Rockwood Specialties, the Target Companies, nor any of their Affiliates has communicated to any employee of the Target Companies or formally adopted or authorized any creation, material modification or termination of any Target Company Benefit Plan, other than as may be required by Applicable Law or the terms of any applicable collective bargaining agreement, Material Contracts or any Target Company Benefit Plan.

(c) (i) No Target Company Benefit Plan is subject to Sections 412 or 430 of the Code or Title IV or Sections 302 or 303 of ERISA.

(ii) No Target Company Benefit Plan is a “multiemployer plan” (as such term is defined in Section 4001(a)(3) of ERISA).

(iii) No Target Company has incurred, and no event has occurred and no condition or circumstance exists that could result, directly or indirectly, in, any material liability (including, without limitation, any indirect, contingent or secondary liability) of any Target Company under Title IV of ERISA or Sections 412 or 430 of the Code or Sections 302 or 303 of ERISA.

(iv) No Target Company Benefit Plan (whether qualified or non-qualified under Section 401(a) of the Code) provides for post-employment or retiree health, life insurance or other welfare benefits and has unfunded liabilities, other than continuation coverage required by Section 4980B of the Code or Sections 601-608 of ERISA (“COBRA”) or similar Legal Requirements.

(v) No asset of any Target Company is subject to any Lien arising under Section 303(k) of ERISA or Section 430(k) of the Code, and no event has occurred and no condition or circumstance has existed that could give rise to any such Lien. None of the Target Companies has been required to provide any security under Section 307 of ERISA or Section 436(f) of the Code, and no event has occurred and no condition or circumstance has existed that could give rise to any such requirement to provide any such security.

(vi) There are no Claims or disputes pending or to the Knowledge of Rockwood, threatened, anticipated or expected to be asserted against or with respect to any Benefit Plan or the assets of any such Benefit Plan (other than routine claims for benefits and appeals of denied routine claims) that could, individually or in the aggregate, result in a material liability of any Target Company. No civil or criminal action brought pursuant to the provisions of Title I, Subtitle B, Part 5 of ERISA is pending, or to the Knowledge of Rockwood, threatened, anticipated, or expected to be asserted against any Target Company or any fiduciary of any Benefit Plan, in any case with respect to any Benefit Plan that could, individually or in the

aggregate result in a material liability of any Target Company. No Benefit Plan or any fiduciary thereof has been the direct or indirect subject of any Proceeding that could, individually or in the aggregate, result in a material liability of any Target Company.

(d) Full payment has been timely made of all amounts that any Target Company is required, under applicable Legal Requirement or under the terms of any Target Company Benefit Plan or any agreement relating to any Target Company Benefit Plan to which any Target Company is a party, to have paid as contributions or premiums thereto as of the last day of the most recent fiscal year of such Target Company Benefit Plan ended prior to the date hereof or have been timely reflected on the most recent consolidated balance sheet filed prior to the date hereof or accrued in the account records of the Target Companies and such contributions or premiums have been timely deposited into the appropriate trusts or accounts.

(e) None of the Target Companies, nor any of their respective directors, officers, or employees has engaged in any transaction with respect to any Benefit Plan or breached any applicable fiduciary responsibilities or obligations under Title I of ERISA that would subject any of them to a Tax, penalty or liability for prohibited transactions or breach of any obligations under ERISA or the Code or would result in any Claim being made under, by or on behalf of any such Benefit Plan by any party with standing to make such Claim, except to the extent that any such transaction or breach could not, individually or in the aggregate, result in a material liability of any Target Company.

(f) The execution of this Agreement and the consummation of the Contemplated Transactions do not constitute a triggering event under any Target Company Benefit Plan, which (either alone or upon the occurrence of any additional or subsequent event) will result in any payment (whether of severance pay or otherwise), “parachute payment” (as such term is defined in Section 280G of the Code), acceleration, vesting or increase in benefits to any employee or former employee or director of any Target Company. Except as set forth on Schedule 3.14(f) of the Seller Disclosure Letter, no Target Company Benefit Plan provides for the payment of severance, termination, change in control or similar-type payments or benefits.

(g) The Target Companies have classified all individuals who perform services for them correctly under each Target Company Benefit Plan, ERISA, the Code and other applicable Legal Requirements as common law employees, independent contractors or leased employees.

(h) With respect to each Target Company Benefit Plan, Rockwood Specialties has made available to the Purchasers true, correct and complete copies of: (i) all Target Company Benefit Plans as in effect on the date hereof, together with all amendments thereto, including, in the case of any Target Company Benefit Plan not set forth in writing, a written description thereof; (ii) all current summary plan descriptions and summaries of material modifications; (iii) all current trust agreements, declarations of trust and other documents establishing other funding arrangements (and all amendments thereto and the latest financial statements thereof); (iv) the most recent IRS determination letter or opinion letter, if any, obtained with respect to each Target Company Benefit Plan intended to be qualified under Section 401(a) of the Code or exempt under Section 501(a) or 501(c)(9) of the Code; (v) the annual report on IRS Form 5500-series or 990 for each of the last three years for each Target Company Benefit Plan required to file such form; (vi) the two most recently prepared actuarial valuation reports; (vii) the most

(i) The UK Plan is a registered pension scheme within the meaning of the UK Finance Xxx 0000, and Rockwood Specialties is not aware of any reason why the UK Plan’s registered status will or may cease.

(j) No Target Company has been a party to an act, or a deliberate failure to act, which might result in a contribution notice being issued to any Target Company by TPR under section 38 or 47 of the PA04 in respect of the UK Plan. No Target Company has at any time within the 12 months before the Closing Date been “connected” with or an “associate” of any employer that is or has been participating in a pension scheme established in the U.K. (other than the UK Plan) to which sections 38, 43, 47 or 52 of the PA04 applies (for these purposes, “connected” and “associate” have the meanings given to them in sections 435 and 249 of the UK Insolvency Xxx 0000, respectively). No financial support direction, contribution notice or restoration order has been issued by TPR under sections 38, 43, 47 or 52 of the PA04 against any Target Company or any of their directors and to the Knowledge of Rockwood there are no circumstances that are likely to lead to any direction, notice or order being issued.

(a) The Purchasers’ Representative shall promptly notify the Sellers’ Representative upon receipt by the Purchasers or any Related Persons of any Purchaser (including the Target Companies after the Closing Date) of written notice of any inquiries, claims, assessments, audits or similar events with respect to Taxes relating to a taxable period ending on or prior to the Closing Date for which the Rockwood Sellers may be liable under this Agreement (any such inquiry, claim, assessment, audit or similar event, a “Tax Matter”). The Rockwood Sellers or the Sellers’ Representative, at their or its sole expense, shall have the authority to represent the interests of the Target Companies with respect to any Tax Matter before any Tax authority, other Governmental Body or any court and shall have the sole right to control the defense, compromise or other resolution of any Tax Matter, including responding to inquiries, filing Tax Returns and contesting, defending against and resolving any assessment for additional Taxes or notice of Tax deficiency or other adjustment of Taxes of, or relating to, a Tax Matter; provided, however, that neither the Rockwood Sellers nor any of their Related Persons shall enter into any settlement of or otherwise compromise any Tax Matter that adversely affects or may adversely affect the Tax liability of the Purchasers, any Subsidiaries of the Purchasers, the Target Companies or any Related Persons of the foregoing for any period ending after the Closing Date, including the portion of the Overlap Period that is after the Closing Date, without the prior written consent of the Purchasers, which consent shall not be unreasonably withheld or delayed. The Rockwood Sellers or the Sellers’ Representative shall keep the Purchasers fully and timely informed with respect to the commencement, status and nature of any Tax Matter that may affect the liability of the Target Companies for periods after the Closing. The Rockwood Sellers shall, in good faith, allow the Purchasers to make comments to the Rockwood Sellers or Sellers’ Representative, as the case may be, regarding the conduct of or positions taken in any such proceeding that may affect the liability of the Target Companies for periods after the Closing.

(b) The Sellers’ Representative and the Purchasers’ Representative shall jointly control the defense, compromise or other resolution of any Tax Matter related to an Overlap Period, which control shall be exercised reasonably and in good faith with due regard to the relative Tax liability potentially incurred by either party. The parties shall keep each other fully and timely informed with respect to the commencement, status and nature of any such Tax Matter.

(c) The Purchasers shall have the sole right to control any Tax Matter before any Governmental Body, initiate any claim for refund or amend any Tax Return, and contest, resolve and defend against any assessment for additional Taxes, notice of Tax deficiency or other adjustment of Taxes of or relating to, the income, assets or operations of the Target Companies or the ownership of the Purchased IP or the Purchased Equity Interests for all taxable periods beginning after the Closing Date.

9.4 Transfer Taxes. Except as provided in Section 9.11, all transfer, sales and use, registration, stamp and similar Taxes imposed in connection with the sale of the Purchased IP or Purchased Equity Interests, or any other transaction that occurs pursuant to this Agreement shall be borne solely by the Rockwood Sellers, jointly and severally. The Rockwood Sellers shall promptly reimburse the Purchasers in an amount equal to any such Tax that any Purchaser is required to pay under any applicable Legal Requirement. Notwithstanding the foregoing, any Taxes paid by the Rockwood Sellers pursuant to this Section 9.4, which are thereafter recovered by the Purchasers shall be promptly paid by the recipient of such recovered Taxes to the Rockwood Sellers.

9.5 Amended Tax Returns; Tax Refunds. The Sellers’ Representative (or its designee) will be entitled to retain, or receive prompt payment from Purchasers or any Related Persons of any Purchaser (including the Target Companies after the Closing Date) of, any refund or credit for overpayment of Taxes for which the Rockwood Sellers are responsible pursuant to this Article 9 plus any interest received or credited with respect thereto from the relevant Governmental Body. The Purchasers’ Representative will, if the Sellers’ Representative reasonably requests and at the Sellers’ Representative’s expense, cause Purchasers or any Related Persons of any Purchaser (including the Target Companies after the Closing Date) to promptly file for and obtain any refunds or credits to which the Sellers’ Representative is entitled under this Section 9.5. The Sellers’ Representative may prosecute any such claim for refund and, when deemed appropriate by the Sellers’ Representative, will cause the relevant entity to authorize, by appropriate power of attorney, such person as the Sellers’ Representative may designate to represent such entity with respect to such refund claim; provided, however, that the Sellers’ Representative shall not take any action that could reasonably be expected to adversely affect the Tax liability of Purchasers or any Related Persons of any Purchaser (including the Target Companies after the Closing Date) for taxable periods after the Closing Date without the prior consent of Purchasers’ Representative (which consent shall not be unreasonably withheld or delayed). For purposes of this Section 9.5, a party will be deemed to have made prompt payment of a refund or credit if such payment is made within 10 days of the receipt by such party of such refund or of the use by such party of such credit.

9.6 Prior Tax Agreements. The Sellers shall terminate or cause to be terminated any and all of the Tax sharing, allocation, indemnification or similar Contracts in effect on the Closing Date as between the Rockwood Sellers or any predecessor or Related Person thereof (other than any Target Company), on the one hand, and any Target Company, on the other hand, for all Taxes imposed by any Governmental Body, regardless of the period in which such Taxes are imposed, and there shall be no continuing obligation to make any payments under any such agreements, arrangements or undertakings.

9.7 Indemnification for Taxes. Except as provided in Section 9.11 and except to the extent that such Taxes (a) were deducted in the calculation of Closing Date Working Capital or were paid prior to the Closing or (b) are incurred as a result of any action outside the Ordinary Course of Business after the Closing effected by Purchasers or any Related Persons of any Purchaser (including the Target Companies after the Closing Date) or any Tax election made by Purchasers or any Related Persons of any Purchaser (including the Target Companies after the Closing Date) (other than the election described in Section 9.8 or any such election directed by or consented to by the Rockwood Sellers), the Rockwood Sellers shall indemnify and hold

harmless the Purchasers and their Representatives, shareholders and their Related Persons (the “Purchaser Indemnified Persons”), and will pay the Purchaser Indemnified Persons for: (i) all Taxes (and, for purposes of this Section 9.7 any Damages resulting from, arising from or in connection with, or incurred with respect to, any claims that may be asserted by any Person based on, attributable to, or resulting from the failure of any representation or warranty made pursuant to Section 3.12 to be true and correct in all respects as of the date of this Agreement and as of the Closing Date shall constitute Taxes) imposed on the Target Companies for all Pre-Closing Periods, (ii) all Taxes imposed on the Target Companies with respect to income of the Rockwood Sellers or any of their Related Persons (other than the Target Companies) as a result of the provisions of United States Treasury Regulations Section 1.1502-6 or the analogous provisions of any state, local or foreign Legal Requirement, (iii) all Taxes imposed on the Target Companies, or for which the Target Companies may be liable, on the sale of the Purchased IP and the Reorganization and (v) any Taxes imposed on the deemed sale resulting from the joint election under Section 338(h)(10) of the Code to treat the sale of stock pursuant to this Agreement as an asset sale for U.S. federal income tax purposes, and any analogous provisions of state and local law.

9.8 Section 338 Election.

(a) Rockwood Holdings and Mexichem shall jointly complete and make, or cause to be completed and made, a timely election under Section 338(h)(10) of the Code (with respect to AlphaGary Corporation) on Form 8023 or in such other manner as may be required by rule or regulation of the IRS, and shall jointly make an election in the manner required under any analogous joint election provisions of state or local law concerning the transactions contemplated by this Agreement. Mexichem shall, with the assistance and cooperation of Rockwood Specialties Group and Rockwood Specialties, prepare all such Section 338(h)(10) forms required as attachments to Form 8023 (and all forms under analogous provisions of state or local law) in accordance with applicable Tax Legal Requirements, and Mexichem shall deliver such forms and related documents to Rockwood Specialties Group and Rockwood Specialties at least 60 days prior to the due date of filing. Rockwood Specialties Group and Rockwood Specialties shall deliver to Mexichem, at least 30 days prior to the due date of filing, such duly executed completed forms as are required to be filed under Section 338(h)(10) of the Code (and analogous provisions of state or local law).

(b) The Sellers agree that the Purchasers shall perform or cause to be performed an initial valuation of assets and allocation of purchase price of AlphaGary Corporation for purposes of Section 338 of the Code. The Purchasers shall provide the Rockwood Sellers with drafts of such valuation of assets and allocation and computation of the aggregate deemed sale price (as defined under Treasury Regulations Section 1.338-4) (which shall be prepared on a basis consistent with Section 9.8(a)) within 120 days after the Closing Date. The Rockwood Sellers shall have 45 days to provide the Purchasers with any objections to such drafts. If the Rockwood Sellers shall object to the computation or allocation by the Purchasers of such amounts, and the Purchasers and the Rockwood Sellers shall not reach agreement on the computation or allocation within 30 Business Days after notification by the Rockwood Sellers of their objection, the Purchasers and the Rockwood Sellers shall submit the issue to the Independent Accountant for resolution of the disagreement within 10 days (it being agreed that the Purchasers and the Rockwood Sellers will jointly share the fees and expenses of the

Independent Accountant). The valuations and allocations determined pursuant to this Section 9.8(b) shall be used for purposes of all relevant Tax Returns, reports and filings.

9.9 Pre-Closing Tax Payments. Notwithstanding anything to the contrary herein, any Taxes for a Pre-Closing Period or Overlap Period or that the Rockwood Sellers are otherwise required to pay pursuant to this Article 9, including any estimated Taxes, that are paid prior to the Closing shall be credited against the Rockwood Sellers’ liability for Taxes pursuant to this Article 9 and, to the extent such payments of Taxes exceed the Rockwood Sellers’ liability for such Taxes pursuant to this Article 9, the Purchasers shall pay the amount of such excess to the Rockwood Sellers within five days after the filing of a Tax Return related to such Taxes or the taxable period with respect to which such Taxes were paid.

9.10 Tax Cooperation. After the Closing Date, each of Sellers’ Representative and Purchasers’ Representative shall, and shall cause their respective Related Persons to, provide the other party (subject to reimbursement by the other party for, and only for, any reasonable out-of-pocket expenses), 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 administrative or judicial proceeding relating to liability for Taxes of the Target Companies (or any affiliated, consolidated, combined or unitary group in which any of the Target Companies is included), Sellers’ Representative, Purchasers’ Representative or any of their respective Related Persons. For the avoidance of doubt, Purchasers’ Representative shall timely provide Sellers’ Representative with any information and assistance reasonably required by Sellers’ Representative in connection with any IRS Form 5471 that any Rockwood Seller is required to filed with respect to any Target Company. The parties further agree to retain and provide each other with reasonable access to all books and records relevant to the liabilities of the Target Companies or the Rockwood Sellers (or any of their Related Persons) for Taxes for any periods (or portions thereof) prior to the Closing for at least seven years after the Closing and to give each other notice and an opportunity to receive such books or records prior to destroying or discarding any such books or records.

9.11 Mexican Taxes. Notwithstanding any provision to the contrary in this Agreement, Rockwood Sellers shall not be required to pay or indemnify Purchaser Indemnified Parties from and against, and Purchasers shall be solely responsible for, any Taxes imposed upon the sale of the Purchased IP and the Purchased Equity and any other transaction that occurs pursuant to this Agreement that are imposed by Mexico or any political subdivision or taxing authority thereof or therein.

Rockwood Specialties shall, or shall cause one of its Affiliates (other than a Target Company) to, be responsible for providing continuation of group health coverage required by COBRA or other similar applicable Legal Requirements to any Business Employee employed or engaged in the portion of the Business conducted in the United States (collectively, “U.S. Business Employees”), any former employee of the Business conducted in the United States or any “qualified beneficiary” (within the meaning of Section 4980B of the Code) of any such U.S. Business Employee or former employee of the Business conducted in the United States who incurs a “qualifying event” (within the meaning of Section 4980B of the Code) prior to the Closing Date.

Rockwood Specialties will be responsible for any obligation to provide long-term disability benefits to any Business Employee or any individual formerly employed by the Business who is on long-term disability as of the Closing Date.

Notwithstanding any other provision of this Agreement, the indemnity contained in this Section 10.1(e) shall survive the Closing indefinitely.

(ii) Notwithstanding the generality of Section 10.1(e)(i), if any Section 75 debt arises as a result of the cessation of participation of AGL in the UK Plan, the Rockwood Sellers shall cause Rockwood UK, in its sole discretion, either:

(A) to procure payment to the UK Plan of an amount equal to any such debt (on the basis that any such payment satisfies the obligation to make such payment by AGL);

(B) to enter into a withdrawal agreement complying with Schedule 1A to the Occupational Pension Schemes (Employer Debt Regulations) 2005 (“Employer Debt Regulations”) under which Rockwood UK guarantees payment of Amount B (as determined in accordance with Paragraph 5 of Schedule 1A of the Employer Debt Regulations); or

(C) make such other arrangements with the trustees of the UK Plan by way of scheme apportionment arrangement in accordance with the Employer Debt Regulations or otherwise as have the effect that AGL has no liability for any such Section 75 debt that is not met by Rockwood UK under Section 10.1(e)(i).

(iii) The Purchasers agree that they will (and that following the Closing they will procure that AGL will) provide such information in relation to AGL and/or assistance as Rockwood UK may reasonably require in order to agree with the trustees of the UK Plan and/or the U.K. Pensions Regulator any arrangements referred to in this Section 10.1(e) and confirms that AGL will, if so required by Rockwood UK, enter into any such agreement in such form as Rockwood UK may reasonably require in order to implement those arrangements on the basis that (i) any amounts payable by AGL under such agreement and (ii) any reasonable expenses of AGL in relation to the entering into of such agreement, will be met by Rockwood UK in accordance with the provisions of this Section 10.1(e).

(g) Cooperation. Upon request, Rockwood Specialties shall provide to the Purchasers, and the Purchasers shall provide to Rockwood Specialties, such documents, data and information as may reasonably be necessary to implement the provisions of this Section 10.1 and to administer their respective benefit plans.

(h) General. Nothing herein expressed or implied shall confer upon any of the employees of Rockwood Specialties, the Purchasers, the Target 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.

Except as otherwise set forth in this Section 11.2, each party’s right of termination under Section 11.1 is in addition to any other rights it may have under this Agreement or otherwise, and the exercise of a right of termination will not be an election of remedies. If this Agreement is terminated pursuant to Section 11.1, all further obligations of the parties under this Agreement will terminate, except that the obligations in Section 5.4, Section 5.6, this Section 11.2 and Article 12 and Article 13 will survive; provided, however, that, unless otherwise set forth in Section 12.1, if this Agreement is terminated by a party because of the breach of the Agreement by the other party or because one or more of the conditions to the terminating party’s obligations under this Agreement is not satisfied as a result of the other party’s failure to comply with its obligations under this Agreement, the terminating party’s right to pursue all legal remedies will survive such termination unimpaired.

respect to, or any knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing Date, with respect to the accuracy or inaccuracy of or compliance with any such representation, warranty, covenant or obligation. The waiver of any condition based upon the accuracy of any representation or warranty, or on the performance of or compliance with any covenant or obligation, will not affect the right to indemnification, reimbursement or other remedy based upon such representations, warranties, covenants and obligations.

(i) any failure of any representation or warranty made by the Purchasers in this Agreement or in any Ancillary Document delivered by the Purchasers to be true and correct in all respects on and as of the date of this Agreement and on and as of the Closing Date as if made on such date (other than those made on a specified date, which shall be true and correct in all respects as of such specified date);

(b) Notwithstanding this Section 12.3(b), (i) the Purchasers shall not be required to indemnify any Seller Indemnified Person for Damages with respect to any Claim for indemnification pursuant to clause (i) of Section 12.3(a): (A) if the Damages relating thereto (together with all Damages arising out of the same event or occurrence or series of related events or occurrences or recurring Damages of a similar nature) are less than twenty five thousand Dollars ($25,000) in the aggregate (and such Claim shall be disregarded and shall not be aggregated for purposes of clause (i)(B) of this Section 12.3(b)) and (B) unless and until the aggregate amount of all Claims against the Purchasers under clause (i) of Section 12.3(a) exceeds on a cumulative basis an amount equal to the Basket Amount, in which case the Indemnified Person shall be entitled to recover the Basket Amount, as well as the amount of Claims in excess of the Basket Amount, (ii) the cumulative indemnification obligations of the Purchasers under clause (i) of Section 12.3(a) shall in no event in the aggregate exceed 30% of the Purchase Price and (iii) the cumulative indemnifications of the Purchasers under Section 12.3(a) shall in no event exceed the Purchase Price.

In addition, none of the limitations set forth in this Section 12.3(b) shall not apply to Damages that arise from fraud by an Indemnifying Person.

12.4 Third-Party Claims.

(a) Promptly after receipt by a Person entitled to indemnity under Section 12.2 or 12.3 (an “Indemnified Person”) of notice of the assertion of a Claim by a Third Party (a “Third-Party Claim”) against it, such Indemnified Person shall give written notice to the Person obligated to indemnify under such Section (an “Indemnifying Person”) of the assertion of such Third-Party Claim describing in reasonable detail the basis of such Claim, provided that the failure to notify the Indemnifying Person will not relieve the Indemnifying Person of any liability that it may have to any Indemnified Person, except to the extent that the Indemnifying Person demonstrates that the defense of such Third Party Claim is prejudiced by the Indemnified Person’s failure to give such notice.

(b) If an Indemnified Person gives notice to the Indemnifying Person pursuant to Section 12.4(a) of the assertion of a Third-Party Claim, the Indemnifying Person shall be entitled to participate in the defense of such Third-Party Claim and, to the extent that it wishes (unless the Indemnifying Person is also a Person against whom the Third-Party Claim is made and the Indemnified Person determines in good faith that joint representation would be inappropriate) with respect to such Third-Party Claim), to assume the defense of such Third-Party Claim with counsel reasonably satisfactory to the Indemnified Person. After notice from the Indemnifying Person to the Indemnified Person of its election to assume the defense of such Third-Party Claim, the Indemnifying Person shall not, so long as it diligently conducts such defense, be liable to the Indemnified Person under this Article 12 for any fees of other counsel or any other expenses with respect to the defense of such Third-Party Claim, in each case subsequently incurred by the Indemnified Person in connection with the defense of such Third-Party Claim. If the Indemnifying Person assumes the defense of a Third-Party Claim, (i) such assumption will conclusively establish for purposes of this Agreement that the claims made in that Third-Party

Claim are within the scope of and subject to indemnification, and (ii) no compromise or settlement of such Third-Party Claims may be effected by the Indemnifying Person without the Indemnified Person’s consent unless (A) there is no finding or admission of any violation of Legal Requirement or any violation of the rights of any Person; (B) the sole relief provided is monetary damages that are paid in full by the Indemnifying Person; and (C) the Indemnified Person shall have no liability with respect to any such compromise or settlement of such Third-Party Claims effected without its consent. If notice is given to an Indemnifying Person of the assertion of any Third-Party Claim and the Indemnifying Person does not, within 30 days after notice is given to the Indemnified Person, give notice to the Indemnified Person of its election to assume the defense of such Third-Party Claim, the Indemnifying Person will be bound by any determination made in such Third-Party Claim, or any compromise or settlement effected, by the Indemnified Person with the prior consent of the Indemnifying Person (which consent may not be unreasonably withheld, delayed or conditioned), and will not be required to indemnify Purchaser Indemnified Parties in respect of any such determination made or compromise or settlement effected without such consent.

(c) Notwithstanding the foregoing, if an Indemnified Person determines in good faith that there is a reasonable probability that a Third-Party Claim may adversely affect it or its Related Persons other than as a result of monetary damages for which it would be entitled to indemnification under this Agreement, the Indemnified Person may, by notice to the Indemnifying Person, assume the exclusive right to defend, compromise or settle such Third-Party Claim, but the Indemnifying Person will not be bound by any determination of any Third-Party Claim so defended for the purposes of this Agreement or any compromise or settlement effected without its consent (which may not be unreasonably withheld, delayed or conditioned).

(d) The Sellers hereby consent to the non-exclusive jurisdiction of any court in which a Proceeding in respect of a Third-Party Claim is brought against any Purchaser Indemnified Person for purposes of any claim that a Purchaser Indemnified Person may have under this Agreement with respect to such Proceeding or the matters alleged therein and agree that process may be served on the Seller with respect to such a claim anywhere in the world.

(e) The Indemnified Person and the Indemnifying Person, as the case may be, shall keep the other Person informed of the status of such Third-Party Claim and any related Proceedings at all stages thereof where such Person is not represented by its own counsel, and (ii) the parties agree (each at its own expense) to render to each other such assistance as they may reasonably require of each other and to cooperate in good faith with each other in order to ensure the proper and adequate defense of any Third-Party Claim.

(f) The parties shall cooperate in such a manner as to preserve in full (to the extent possible) the confidentiality of all confidential information and the attorney-client and work-product privileges. In connection therewith, each party agrees that: (i) it will use its commercially reasonable efforts, in respect of any Third-Party Claim in which it has assumed or participated in the defense, to avoid production of confidential information (consistent with applicable law and rules of procedure), and (ii) all communications between any party hereto and counsel responsible for or participating in the defense of any Third-Party Claim shall, to the extent possible, be made so as to preserve any applicable attorney-client or work-product privilege.

12.5 Other Claims. A claim for indemnification for any matter not involving a Third-Party Claim shall be asserted by written notice to the party from whom indemnification is sought and shall be shall be made as promptly as practicable after the time the Indemnified Person becomes aware of the facts forming the basis of such claim.

12.6 Indemnification in Case of Strict Liability or Indemnitee Negligence. The indemnification provisions in this Article 12 shall be enforceable regardless of whether the liability of the person seeking indemnification is based upon a claim of negligence or strict liability, and regardless of whether any person (including the person from whom indemnification is sought) alleges or proves the sole, concurrent, contributory or comparative negligence of the person seeking indemnification or the sole or concurrent strict liability imposed upon the person seeking indemnification.

12.7 Interest. In the event that any amount due to any Purchaser Indemnified Person or Seller Indemnified Person, as the case may be, under this Article 12 or Section 9.7 is not paid when due, the party required to make payment shall pay interest on such amount at a rate of six percent (6%) per annum, based on a 360-day year, from the date such amount is payable to the date of actual payment.

12.8 Exclusive Remedy. The indemnity provided for in this Article 12 and Section 9.7 shall constitute the parties’ sole and exclusive remedy with respect to each other for any and all Claims for Damages (but not specific performance or other equitable remedies) relating to this Agreement and the Contemplated Transactions; provided that nothing herein shall limit in any way any such party’s remedies in respect of fraud by the other party in connection with the Contemplated Transactions. In furtherance of but subject to the foregoing, each party hereby waives, from and after the Closing, to the fullest extent permitted under applicable Legal Requirement, any and all other rights, claims and causes of action (other than fraud by the other party) that it has against the other party (or any Related Person of the other party) in connection with this Agreement or the Contemplated Transactions.

12.9 Additional Limitations; Adjustments; Mitigation.

(a) Any indemnity payment made by the Purchasers on the one hand, or the Rockwood Sellers, on the other hand, pursuant to this Article 12 and Section 9.7 in respect of any Damage shall be (a) reduced by any insurance proceeds under applicable insurance policies actually received by a party entitled to indemnification under this Agreement in respect of such claim and (b) increased by (i) the aggregate cost of pursuing any related insurance claims and (ii) any related increases in insurance premiums resulting from insurance recoveries. The Purchasers and the Rockwood Sellers each agree that they will (and cause their Affiliates to) use commercially reasonable efforts to recover any such insurance proceeds under applicable insurance policies to the extent such recoveries would reduce amounts required to be paid by any party pursuant to this Article 12.

The Purchasers and

the Rockwood Sellers shall cooperate with each other with respect to resolving any Claim or liability with respect to which one party is obligated to indemnify the other party hereunder, including by using reasonable efforts to minimize Damages or resolve any such Claim or liability and acting in good faith in responding to, defending against, settling or otherwise dealing with such Claim.

(c) Notwithstanding any other provision of this Agreement, the Rockwood Sellers shall not be responsible for any Damages for which indemnification would otherwise be available pursuant to clause (iii) of Section 12.2(a) or clause (i) of Section 12.2(a) (in respect of a breach of a representation and warranty set forth in Section 3.19 (Environmental Matters)) to the extent that such Damages would not have arisen but for initiation of any communication with or notice to a Governmental Body or any other Person, except to the extent such initiation of communication or notice (i) is required by Environmental Law (including Governmental Authorizations issued thereunder), other than any such requirement triggered by (A) the expansion in any manner, the closure or the demolition after the Closing of any part of any Facility owned or operated by a Target Company as of the Closing Date, (B) any zoning or land use Legal Requirements imposed after the Closing Date or (C) any change after the Closing in the use of any Facility, (ii) has been approved in writing by the Sellers’ Representative or (iii) notwithstanding clause (i), is required by applicable Environmental Law (including Governmental Authorizations issued thereunder) to be made in connection with the expansion of the Business’ Pineville, North Carolina facility.

The arbitration tribunal will consist of three arbitrators. Each party shall nominate one arbitrator, and the two party-appointed arbitrators shall appoint the chair, except that in the event there are more than two parties in the arbitration the arbitration tribunal shall be constituted in accordance with the ICDR Rules.
