CLI-2060753v12

ARTICLE I

Purchase and Sale; Closing

SECTION 1.01. Purchase and Sale of the Subject Shares. At the Closing, the Sellers shall sell, transfer and deliver or cause to be sold, transferred and delivered to Purchaser, and Purchaser shall purchase from the Sellers, the Subject Shares.

SECTION 1.02. Purchase and Sale of the Purchased Assets. At the Closing, the Sellers shall sell, convey, transfer, assign and deliver, or cause to be sold, conveyed, transferred, assigned and delivered, to Purchaser all of the assets set forth on Schedule I (the “Purchased Assets”). The purchase and sale of the Subject Shares and the Purchased Assets and the assumption and transfer of the Assumed Liabilities is referred to in this Agreement as the “Acquisition”. For the avoidance of doubt, the Subject Shares do not constitute Purchased Assets. Accordingly, Section 1.04 and 1.05 are not applicable to the Subject Shares.

SECTION 1.03. Excluded Assets. Purchaser expressly understands and agrees that all assets of the Sellers other than the Subject Shares and the Purchased Assets shall remain the property of Sellers and their applicable subsidiaries (collectively, the “Excluded Assets”).

SECTION 1.04. Assumed Liabilities. At the Closing, upon the terms and subject to the conditions of this Agreement, Purchaser shall assume the Liabilities of the Sellers to the extent relating to or arising out of the Purchased Assets, including those set forth on Schedule II (the “Assumed Liabilities”). Purchaser’s obligations under this Section 1.04 shall not be subject to offset or reduction, whether by reason of any actual or alleged breach of any representation, warranty or covenant contained in any agreement or document delivered in connection with this Agreement or any right to indemnification hereunder or otherwise.

SECTION 1.05. Excluded Liabilities. Purchaser is assuming only the Assumed Liabilities from the Sellers and is not assuming any other Liability of the Sellers of whatever nature, whether presently in existence or arising hereafter. All such other Liabilities shall be retained by and remain Liabilities of the Sellers, as applicable (all such Liabilities not being assumed being herein referred to as the “Excluded Liabilities”).

SECTION 1.06. Limitations on Assignment of Purchased Assets. Notwithstanding anything in this Agreement to the contrary, this Agreement shall not constitute an agreement to assign any Purchased Asset or any right thereunder if an attempted assignment, without the consent of, or other action by, any third party, would constitute a breach thereunder or in any way adversely affect the rights of Purchaser or the Sellers or any of their respective affiliates thereunder; provided that the foregoing shall not limit or affect the Sellers’ representations and warranties in Articles II and III or the conditions set forth in Section 6.02. Each Seller and Purchaser shall use their respective reasonable best efforts (but without any payment of money) to obtain the consent of such third parties to any such Purchased Asset or any right thereunder for the assignment thereof to Purchaser as Purchaser may reasonably request. If such consent is not obtained or such other action is not taken, the Sellers and Purchaser shall cooperate in a mutually agreeable manner to establish an arrangement under

CLI-2060753v12

which Purchaser would obtain the benefits and assume the obligations thereunder in accordance with this Agreement, including sub-contracting, sub-licensing, or sub-leasing to Purchaser or an affiliate designated by Purchaser, or under which a Seller or any of its affiliates would enforce (at the reasonable direction of Purchaser) for the benefit of Purchaser or its designated affiliate, with Purchaser or its designated affiliate assuming the obligations of such Seller or its affiliates, any and all rights of such Seller or any of its affiliates against a third party thereto (including, if applicable, the right to elect to terminate such Purchased Asset in accordance with the terms thereof upon Purchaser’s request). Each Seller shall promptly pay to Purchaser or its designated affiliate when received all monies received by such Seller or any of its affiliates under any Purchased Asset or any claim or right or any benefit arising thereunder, except to the extent the same represents an Excluded Asset. Upon receipt of any required consents to assignment of a Purchased Asset, the applicable Seller shall, or shall cause its affiliates to, sell, convey, transfer, assign and deliver such Purchased Asset to Purchaser with no additional purchase price due therefore. In addition, following the Closing, the parties shall execute and deliver, or shall cause to be executed and delivered, such documents and other instruments and shall take, or shall cause to be taken, such further actions as may be reasonably required to carry out this Section 1.06 and give effect to the transactions contemplated by this Section 1.06.

SECTION 1.07. Purchase Price; Allocation of Purchase Price

(a) The purchase price for the Purchased Assets and the Subject Shares is $325,000,000 in cash (the “Base Purchase Price”) plus the amount of payments, if any, to be paid by Purchaser pursuant to the provisions set forth in Exhibit A upon the terms and conditions set forth therein (together with the Base Purchase Price, the “Purchase Price”). The Base Purchase Price shall be paid as provided in Section 1.09, and the Base Purchase Price shall be subject to adjustment as provided in Section 1.10.

(b) The Base Purchase Price shall be allocated to the Purchased Assets and the Subject Shares as set forth in the statement attached hereto as Schedule III (the “Allocation Statement”). If an adjustment is made with respect to the Base Purchase Price pursuant to Section 1.10, the Allocation Statement shall be adjusted consistent therewith.

SECTION 1.08. Closing Date. The closing of the Acquisition (the “Closing”) shall take place at the offices of ▇▇▇▇▇ Day, ▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇, ▇▇▇▇, ▇▇▇▇▇ U.S.A., at 10:00 a.m. on the business day that is the second full business day after the date on which the conditions set forth in Article VI are satisfied (or, to the extent permitted, waived by the parties entitled to the benefits thereof), or at such other place, time and date as shall be agreed among the Sellers and Purchaser. The date on which the Closing occurs is referred to in this Agreement as the “Closing Date”.

SECTION 1.09. Closing Deliveries. At the Closing, Purchaser shall deliver to the Sellers the following:

(i) payment, by wire transfer to one or more bank accounts designated in writing by the Sellers (such designation to be made by the Sellers at least three business days prior to the Closing Date), of an amount in immediately available

CLI-2060753v12

funds equal, in the aggregate, to the Base Purchase Price less an amount equal to Certified Indebtedness plus an amount equal to the estimated amount of Cash on Hand as of the close of business on the Closing Date (“Estimated Cash on Hand”) as set forth in a certificate delivered by the Sellers to Purchaser no later than three business days prior to the Closing. Sellers will use reasonable efforts to ensure that Estimated Cash on Hand shall be approximately $30,000,000;

(ii) payment to the applicable lenders, by wire transfer to one or more bank accounts designated in writing by the Sellers (such designation to be made by the Sellers on a business day that is at least three full business days prior to the Closing Date), of an amount equal to Certified Indebtedness;

(iii) the certificate to be delivered pursuant to Section 6.03;

(iv) a counterpart of the Transition Services Agreement attached as Exhibit B hereto (the “Transition Services Agreement”), duly executed by OMG Kokkola Chemicals;

(v) a counterpart of the Cobalt Alloy Sales Agreement attached as Exhibit C hereto (the “Cobalt Alloy Sales Agreement”), duly executed by OMG Kokkola Chemicals and Purchaser Guarantor;

(vi) a counterpart of the Distribution Agreement attached as Exhibit D hereto (the “Distribution Agreement”), duly executed by OMG Kokkola Chemicals; and

(vii) a counterpart of the Services Agreement attached as Exhibit E hereto (the “Services Agreement”), duly executed by OMG Kokkola Chemicals.

(b) At the Closing, the Sellers shall deliver, or cause to be delivered to Purchaser the following:

(i) to the extent the Subject Shares are represented by certificates, such certificates, duly endorsed in blank or accompanied by stock powers duly endorsed in blank in proper form for transfer, with appropriate transfer tax stamps, if any, affixed;

(ii) the certificate to be delivered pursuant to Section 6.02;

(iii) such deeds, bills of sale, endorsements, assignments and other good and sufficient instruments of conveyance and assignment as the parties and their respective counsel shall deem reasonably necessary to vest in Purchaser all right, title and interest in, to and under the Purchased Assets and to evidence Purchaser’s assumption of the Assumed Liabilities;

(iv) duly signed resignations, effective immediately after the Closing, of all directors of the Companies;

CLI-2060753v12

(v) a counterpart of the Transition Services Agreement duly executed by the Sellers;

(vi) a counterpart of the Cobalt Alloy Sales Agreement duly executed by OMG Finland;

(vii) a counterpart of the Distribution Agreement duly executed by OMG Americas;

(viii) a counterpart of the Services Agreement duly executed by OMG Americas; and

(ix) evidence reasonably satisfactory to Purchaser that the Contract listed as item 31 on Section 3.09(a)(ii) of the Seller Disclosure Letter has been amended to remove OMG Kokkola Chemicals as a party thereto.

SECTION 1.10. Purchase Price Adjustment.

(a) Within 60 days after the Closing Date, Purchaser shall cause to be prepared and delivered to the Sellers a working capital statement (the “Final Working Capital Statement”), setting forth the Net Working Capital as of the close of business on the Closing Date (the “Final Working Capital”) and Cash on Hand as of the close of business on the Closing Date (the “Final Cash on Hand”). The Final Working Capital Statement shall be prepared in accordance with the same accounting principles, practices, methodologies and policies used in the preparation of the Working Capital Statement.

(b) Within 30 days following receipt by the Sellers of the Final Working Capital Statement, the Sellers shall deliver written notice to Purchaser of any dispute the Sellers have with respect to the preparation or content of the Final Working Capital Statement; provided, however, that the Sellers may not dispute the accounting principles, practices, methodologies and policies used in preparing the Final Working Capital Statement if they are the same as the accounting principles, practices, methodologies and policies used in preparing the Working Capital Statement. If the Sellers do not so notify Purchaser of a dispute with respect to the Final Working Capital Statement within such 30-day period, such Final Working Capital Statement will be final, conclusive and binding on the parties. In the event of such notification of a dispute, Purchaser and the Sellers shall negotiate in good faith to resolve such dispute. If Purchaser and the Sellers, notwithstanding such good faith effort, fail to resolve such dispute within 15 days after the Sellers advise Purchaser of their objections, then Purchaser and the Sellers jointly shall engage KPMG, LLP (the “Accounting Firm”) to resolve such dispute. As promptly as practicable, and in any event not more than 15 days thereafter, Purchaser and the Sellers shall each prepare and submit a presentation detailing each party’s complete statement of proposed resolution of the dispute to the Accounting Firm. As soon as practicable thereafter, Purchaser and the Sellers shall cause the Accounting Firm to choose one of the parties’ positions based solely upon the presentations by Purchaser and the Sellers. The parties shall share the expenses of the Accounting Firm equally. All

CLI-2060753v12

determinations made by the Accounting Firm will be final, conclusive and binding on the parties.

(c) For purposes of complying with the terms set forth in this Section 1.10, each party shall cooperate with and make available to the other parties and their respective representatives all information, records, data and working papers, and shall permit access to its facilities and personnel, as may be reasonably required in connection with the preparation and analysis of the Final Working Capital Statement and the resolution of any disputes thereunder (subject to reasonable confidentiality restrictions and to providing such assurances, releases, indemnities or other agreements as accountants may customarily require in such circumstances).

(d) If the Target Working Capital and Estimated Cash on Hand, when taken together, exceed Final Working Capital and Final Cash on Hand, when taken together (each, as finally determined pursuant to Section 1.10(b)), then the Base Purchase Price will be adjusted downward by the amount of such excess, and the Sellers shall pay or cause to be paid an amount in cash equal to such excess to Purchaser by wire transfer of immediately available United States funds to an account or accounts designated in writing by Purchaser to the Sellers. Any such payment is to be made within five business days of the date on which the Final Working Capital is finally determined pursuant to this Section 1.10.

(e) If the Final Working Capital and Final Cash on Hand, when taken together (each, as finally determined pursuant to Section 1.10(b)), exceed the Target Working Capital and Estimated Cash on Hand, when taken together, then the Base Purchase Price will be adjusted upward by the amount of such excess, and Purchaser shall pay or cause to be paid an amount in cash equal to such excess to the Sellers by wire transfer of immediately available United States funds to an account or accounts designated in writing by the Sellers to Purchaser. Any such payment is to be made within five business days of the date on which the Final Working Capital is finally determined pursuant to this Section 1.10.

SECTION 1.11. Withholding. Either party hereto or any of their respective affiliates (including, effective upon the Closing with respect to Purchaser, the Companies), shall be entitled to deduct and withhold from any amount otherwise payable to the other party hereto pursuant to this Agreement such amounts as they are required to deduct and withhold with respect to the making of such payment under any applicable Law. If any amount is so withheld, such withheld amounts shall be timely paid to the appropriate Tax Authority and treated for all purposes of this Agreement as having been paid to such other party hereto.

obtain such exemptions. For the avoidance of doubt, such Transfer Taxes shall include the Finland Security Transaction Tax.

(b) At or prior to the Closing, Purchaser shall make, or shall cause one of its affiliates to make, offers of employment to each of the individuals identified in Section 5.07(a) of the Seller Disclosure Letter that are not employees of a Company (the “Transferred Employees”), so long as they otherwise qualify for employment by Purchaser based on the hiring criteria set forth in Section 5.07(a) of the Disclosure Letter.

Any offers of employment will be made in compliance with Purchaser’s usual and customary hiring procedures, which may include, as permitted by applicable Law, the successful completion of drug tests and background checks. Such employment offers shall provide compensation and employee benefits that are substantially similar in the aggregate to those applicable to such Transferred Employees immediately prior to the Closing; provided, however, that the value of any previous agreement entered into by any individual with the Sellers that would trigger any payment of compensation or benefits solely as a result of the consummation any of the transactions contemplated hereby shall not be included in any such determination. Purchaser shall give Transferred Employees full credit for purposes of eligibility, vesting and benefit accruals (other than benefit accrual under a defined benefit pension plan (other than any Company Plan)) under the Employee Plans or other comparable benefit plans in which such Transferred Employee participates to the same extent recognized under the Employee Plans or other comparable benefit plans, as applicable, immediately prior to the Closing. Purchaser, the Companies and their affiliates shall have no obligations or liabilities (i) with respect to any current or former individual service providers to the Business (including employees and independent contractors of the Sellers or the Business) other than Business Employees (including Transferred Employees), (ii) with respect to liabilities relating to the Business Employees who are not employees of the Companies, which liabilities arose or were incurred prior to the Closing, other than obligations and liabilities imposed under Company Plans and (iii) any liabilities or obligations that arise under the Retention Agreements.

(b) If any provision contained in this Section 5.13 shall for any reason be held invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provisions of this Section 5.13, but this Section 5.13 shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein. It is the intention of the parties that if any of the restrictions or covenants contained herein is held to cover a geographic area or to be for a length of time which is not permitted by applicable Law, or in any way construed to be too broad or to any extent invalid, such provision shall not be construed to be null, void and of no effect, but to the extent such provision would be valid or enforceable under applicable Law, a court of competent jurisdiction shall construe and interpret or reform this Section 5.13 to provide for a covenant having the maximum enforceable geographic area, time period and other provisions (not greater than those contained herein) as shall be valid and enforceable under such applicable Law. The Sellers acknowledge that Purchaser may be irreparably harmed by any breach of this Section 5.13 and that there would be no adequate remedy at law or in damages to compensate Purchaser for any such breach.

SECTION 5.14. Insurance Policies. The Sellers shall use reasonable efforts in good faith to facilitate the making of any claims by the Companies under the Policies. If any Policy does not permit the Companies to directly file a claim, the Sellers or their affiliates shall file such claim on behalf of the Companies and shall use reasonable best efforts to seek

CLI-2060753v12

reimbursement under the applicable Policy. Any reimbursement obtained by the Sellers or their affiliates shall be promptly remitted to the Companies, as applicable.

SECTION 5.15. No Further Financial Obligations. Purchaser acknowledges that in the course of conduct by the Companies of their respective businesses, Sellers, and their respective affiliates, and direct and indirect subsidiaries of any of them (collectively, but excluding the Companies, the “OM Group Entities”) entered into various arrangements (i) in which guarantees were issued by the OM Group Entities and (ii) in which the OM Group Entities are the primary obligors on other agreements, in any such case to support or facilitate business transactions or programs of the Companies, including those arrangements set forth in Section 5.15 of the Sellers Disclosure Letter. The arrangements referred to in the foregoing clauses (i) and (ii) are hereinafter referred to as the “Guarantees”. It is understood that the Guarantees shall not continue after the Closing. Purchaser agrees that it shall use commercially reasonable efforts to obtain replacements of the Guarantees which will be in effect at the Closing or, in the case of the Guarantees described in the foregoing clause (ii), to arrange for itself or one of its subsidiaries to be substituted as the primary obligor thereon as of the Closing Date. In the event that Purchaser is unable to satisfy the terms of the immediately preceding sentence, Purchaser and its affiliates shall indemnify, defend and hold harmless the OM Group Entities from and against any and all losses and Liabilities of the OM Group Entities relating to the Guarantees.

(a) The Sellers shall cause the provisions of any Tax Sharing Agreement or arrangement between the Sellers or any of their affiliates (other than the Companies) and the Companies, to be terminated on or before the Closing Date. After the Closing Date, no party shall have any rights or obligations under any such Tax Sharing Agreement.

(b) Apportionment. Except as otherwise provided herein, all Taxes and Tax liabilities with respect to the income, property or operations of the Business that relate to any taxable period that includes but does not end on the Closing Date (a “Straddle Period”) shall be apportioned between the Pre-Closing Tax Period and the Post-Closing Tax Period as follows: (a) in the case of Taxes that are either (i) based upon or related to income, receipts, capital or net worth (but not including sales and compensating use Taxes), or (ii) imposed in connection with any sale or other transfer or assignment of property (real or personal, tangible or intangible) (other than conveyances pursuant to this Agreement, as provided under Section 5.06(b)), such Taxes shall be deemed equal to the amount which would be payable if the Tax year ended with the Closing Date; provided, however, that exemptions, allowances or deductions that are calculated on an annual basis shall be allocated between such two periods in proportion to the number of days in such period; and (b) in the case of Taxes imposed on a periodic basis with respect to the Business, or otherwise measured by the level of any item, such Taxes shall be deemed to be the amount of such Taxes for the entire period (or, in the case of such Taxes determined on an arrears basis, the amount of such Taxes for the immediately preceding period), multiplied by a fraction, the numerator of which is the number of calendar days in the period ending on the Closing Date and the denominator of which is the number of calendar days in the entire period. Subject to the previous sentence and Section 8.02(a), the Sellers shall be liable for all Taxes with respect to the Business attributable to a Pre-Closing Tax Period except to the extent taken into account as a liability in the determination of Final Net Working Capital.

CLI-2060753v12

(i) The Sellers or their designee shall prepare and timely file (including extensions), or cause to be prepared and timely filed (including extensions), in proper form with the appropriate Taxing Authority all necessary Tax Returns of or which include or relate to the Business for Pre-Closing Tax Periods that are required to be filed (including extensions) on or prior to the Closing Date (including all Tax Returns the Companies file jointly with a Seller or any of its affiliates (other than the Companies)). The Sellers shall pay or shall cause to be paid any and all Taxes due with respect to such Tax Return filings.

(ii) The Sellers or their designee shall prepare and timely file (including extensions), or cause to be prepared and timely filed (including extensions), in proper form with the appropriate Taxing Authority all consolidated, combined or unitary Tax Returns of the Sellers that include or relate to the Business with respect to any Pre-Closing Tax Period (including any short period) that are not required to be filed on or prior to the Closing Date, other than the consolidated, combined or unitary returns of the Companies. The Sellers shall permit Purchaser to review and comment on each such Tax Return prior to filing it and shall reasonably and in good faith consider such revisions to such Tax Returns as are requested by Purchaser. For the avoidance of doubt, the Sellers shall not be required to revise such Tax Returns to increase income in any Pre-Closing Tax Period, unless otherwise required by Law. The Sellers shall pay or shall cause to be paid any and all Taxes due with respect to such Tax Returns. Purchaser shall provide or cause to be provided to the Sellers in a timely manner all necessary data and other information to prepare all Tax Returns described in this Section 8.01(c)(ii).

(iii) Purchaser or its designee shall prepare and timely file (including extensions), or cause to be prepared and timely filed (including extensions), in proper form with the appropriate Taxing Authority all Tax Returns required to be filed for any Straddle Period of the Business.

Purchaser shall pay or cause to be paid any and all Taxes with respect to the Business due with respect to such Tax Returns except to the extent that such Taxes exceed the aggregate accruals or reserves for Taxes for any Pre-Closing Tax Period taken into account in the determination of Final Net Working Capital. The Sellers shall pay or cause to be paid to Purchaser the amount by which the Tax due for the Pre-Closing Tax Period exceeds the amount taken into account as liability in the determination of Final Net Working Capital for such period at least 5 business days before any Company, any of the Subsidiaries or any of the Sellers files such Tax Return.

(iv) Purchaser shall prepare and file, or shall cause one or more of the Companies to prepare and file, in proper form with the appropriate Taxing Authority, all Tax Returns of or that include the Business for which the Sellers are not responsible pursuant to Sections 8.01(c)(i) and 8.01(c)(ii). Subject to Section

CLI-2060753v12

8.02, Purchaser shall pay or cause to be paid any and all Taxes due with respect to such Tax Returns.

(v) With respect to any Tax Returns for any Straddle Period, to the extent permissible, but not required, pursuant to applicable Tax Law, the Sellers may and Purchaser or its affiliates shall, at the Sellers’ direction, cause the Business to (a) take all steps as are or may be reasonably necessary, including the filing of elections or returns with applicable Taxing Authorities, to cause such period to end on the Closing Date or (b) if clause (a) is inapplicable, report the operations of the Business only for that portion of such period ending on the Closing Date in a combined, consolidated, or unitary Tax Return filed by the Sellers or an affiliate, notwithstanding that such taxable period does not end on the Closing Date.

(vi) Purchaser shall prepare and file in proper form with the appropriate Finnish Taxing Authority, all Tax Returns related to the Finland security transaction tax payable with respect to the estimated value of the Earn-out Payments (the “Finland Security Transaction Tax”). Purchaser shall permit the Sellers to review and comment on each such Tax Return prior to filing it and shall reasonably and in good faith consider such revisions to such Tax Returns as are requested by the Sellers.

(d) Cooperation. In connection with the preparation of Tax Returns, audit examinations, and any administrative or judicial proceedings relating to the Tax liabilities imposed on or relating to the Sellers or the Companies with respect to the Business for all Pre-Closing Tax Periods or the Earn-out Payments, Purchaser and the Companies on the one hand, and the Sellers on the other hand, shall cooperate fully with each other, including by furnishing or making available during normal business hours, records, personnel (as reasonably required and at no cost to the other party), books of account, powers of attorney or other materials necessary or helpful for the preparation of such Tax Returns, the conduct of audit examinations or the defense of claims by Tax authorities as to the imposition of Taxes. The Sellers and their affiliates will need access, from time to time, after the Closing Date, to certain accounting and Tax records and information held by the Business to the extent such records and information pertain to events occurring prior to the Closing Date and during the Straddle Period; therefore, Purchaser shall cause the Business to, (i) use its best efforts to properly retain and maintain such records until such time as the Sellers agree that such retention and maintenance is no longer necessary; (ii) cause the Business to provide to the Sellers information regarding the Businesses’ payment of any non-US taxes relating to any Pre-Closing Tax Period or any Straddle Period and original receipts from the applicable Taxing Authorities showing payment thereof, in each case within 5 business days of the payment of such taxes; and (iii) allow the Sellers and their agents, at times and dates mutually acceptable to the parties, to inspect, review and make copies of such records as the Sellers may deem necessary or appropriate from time to time, such activities to be conducted during normal business hours and at the Sellers’ expense. Any information obtained under this Section 8.01(d) shall be kept confidential, except as may be otherwise necessary in connection with the filing of Tax Returns or claims for refund or in conducting an audit or other proceeding.

CLI-2060753v12

(e) Refunds and Credits. Purchaser shall pay or cause to be paid to the Sellers any Tax refunds or credits, together with interest thereon, with respect to the Business (except to the extent reflected on the Balance Sheet or due as the result of the carry back of a net operating or capital loss arising in a Post-Closing Tax Period) attributable to any Pre-Closing Tax Period or any Tax refunds or credits attributable to the Finland Security Transaction Tax (but in such a case, half of such Tax refund or credit) received by or credited to Purchaser or a Company, net of any direct costs attributable to receipt of such refund or credit, including Taxes payable with respect to such refund, within 10 business days after the receipt of such refund or the realization of such credit. All refunds with respect to the Business attributable to any (i) Post-Closing Tax Period or (ii) Pre-Closing Tax Period not otherwise payable to the Sellers shall be for the benefit of Purchaser and if received by or otherwise credited to the Sellers or any affiliate thereof (other than a Company), the Sellers shall pay or cause to be paid an amount equal to such refund or credit to Purchaser within 10 business days after the receipt of such refund or the realization of such credit. At the Sellers’ request, Purchaser and the Companies shall cooperate with the Sellers in obtaining such refunds, including through the filing of amended Tax Returns or refund claims as prepared by the Sellers, at their own expense. Purchaser shall permit the Sellers to control the prosecution of any such refund claim and, where deemed appropriate by the Sellers, shall authorize by appropriate powers of attorney such persons as the Sellers shall designate to represent the Companies with respect to such refund claim.

(f) None of Purchaser or any of its affiliates or any directors, officers or employees of the foregoing shall make, or permit to be made, any election with respect to, or otherwise change, the entity classification of the Companies for income Tax purposes for any Tax period (or portion thereof) ending on or before the Closing Date without Seller’s consent, which shall not be unreasonably withheld.

(g) The Purchase Price shall be allocated among the assets that are deemed to be acquired for U.S. federal tax purposes pursuant to this Agreement in accordance with Section 1060 of the U.S. Internal Revenue Code of 1986, as amended, and the U.S. Treasury regulations promulgated thereunder (and any similar provision of U.S. state or local Law, as appropriate) (the “U.S. Allocation”). Such allocation shall be consistent with the allocation provided in Section 1.07(b). The U.S. Allocation shall be agreed by Purchaser and the Sellers within 180 days after the Closing Date. If any Earn-out Payment is made, the U.S. Allocation shall be adjusted in accordance with Section 1060 of the Code as mutually agreed by Purchaser and the Sellers within 20 days after the final determination of the Earn-out Payment; provided, however, that any Earn-out Payment made shall be allocated solely to the Subject Shares in a manner consistent with the Allocation Statement and no allocation of any Earn-out Payment shall be made to the Purchased Assets. If Purchaser and the Sellers cannot agree on such allocation or such adjustment within the specified time period, Purchaser and the Sellers shall jointly retain a nationally recognized accounting firm to resolve the disputed items. Purchaser and the Sellers agree to file all Tax Returns (including but not limited to Internal Revenue Service Form 8594) consistent with this allocation.

CLI-2060753v12

(h) No party to this Agreement shall make an election under Section 338 of the Code with respect to the transactions contemplated by this Agreement.

SECTION 8.02. Tax Indemnification. (a) From and after the Closing, the Sellers shall jointly and severally indemnify Purchaser, its affiliates (including the Companies) and each of their respective officers, directors, employees, stockholders, agents, successors, assigns and representatives (the “Purchaser Indemnitees”) against and hold them harmless from (i) all liability for Taxes of the Business or any affiliated group of which the Companies have ever been a member for the Pre-Closing Tax Period (apportioned in accordance with Section 8.01(b)), (ii) all liability for Taxes of the Sellers or any other corporation which is or has been affiliated with the Sellers (other than the Companies) and (iii) any liabilities, costs, expenses (including, without limitation, reasonable expenses of investigation and attorneys’ fees and expenses), losses, damages, assessments, settlements or judgments arising out of or incident to the imposition, assessment or assertion of any such Taxes (together, a “Tax Loss”), provided, however that the Sellers shall not be required to indemnify for any Tax to the extent the amount of such Tax was taken on the Closing Date into account as a liability in the determination of Final Net Working Capital. Notwithstanding the foregoing, the Sellers shall not indemnify and hold harmless any Purchaser Indemnitee from any liability for Taxes attributable to any action taken after the Closing by Purchaser, any of its affiliates (including the Companies), or any transferee of Purchasers or any of its affiliates (other than any such action expressly required by applicable Law or by this Agreement) (a “Purchaser Tax Act”) or attributable to a breach by Purchaser of its obligations under this Agreement.

(b) From and after the Closing, Purchaser shall indemnify the Sellers and their affiliates and each of their respective officers, directors, employees, stockholders, agents and representatives (the “Seller Indemnitees”) and hold them harmless from (i) all liability for Taxes of the Business for any Post-Closing Tax Period, except to the extent arising out of Seller’s breach of representations made under this Agreement and (ii) all liability for Taxes attributable to a Purchaser Tax Act or to a breach by Purchaser of its obligations under this Agreement.

(i) If a claim shall be made by any Taxing Authority, which, if successful, Purchaser reasonably determines could result in an indemnity payment to any Purchaser Indemnitee pursuant to this Section 8.02, Purchaser shall promptly notify the Sellers in writing of such claim (a “Tax Claim”). If notice of a Tax Claim is not given to the Sellers within a sufficient period of time to allow the Sellers to effectively contest such Tax Claim, or in reasonable detail to apprise the Sellers of the nature of the Tax Claim, in each case taking into account the facts and circumstances with respect to such Tax Claim, the Sellers shall not be liable to any Purchaser Indemnitee to the extent that the Sellers’ position is materially prejudiced as a result thereof.

(ii) With respect to any Tax Claim relating solely to Taxes of the Business for a Pre-Closing Tax Period, the Sellers shall control all proceedings taken in connection with such Tax Claim (including selection of counsel

CLI-2060753v12

reasonably satisfactory to the Purchaser) and, without limiting the foregoing, may in its discretion pursue or forego any and all administrative appeals, proceedings, hearings and conferences with any Taxing Authority with respect thereto; provided, however that the Sellers shall consult with Purchaser upon Purchaser’s reasonable request for such consultation from time to time with respect to such proceeding, and may, in their discretion, either pay the Tax claimed and ▇▇▇ for a refund where applicable Law permits such refund suits or contest the Tax Claim in any permissible manner; provided, however the Sellers may not settle any controversy without Purchaser’s consent. With respect to any Tax Claim relating to Taxes of the Business for a Straddle Period, (a) each party may participate in all proceedings taken in connection with such Tax Claim, at its expense, and (b) the proceedings taken in connection with such Tax Claim shall be controlled by that party which would bear the burden of the greater portion of the sum of the adjustment and any corresponding adjustments that may reasonably be anticipated for future Tax periods.

(iii) In no case shall any Purchaser Indemnitee settle or otherwise compromise any Tax Claim without the Sellers’ prior written consent. Neither party shall settle a Tax Claim relating solely to Taxes of the Business for a Straddle Period without the other party’s prior written consent, which consent shall not be unreasonably withheld or delayed.

(iv) The indemnification obligation set forth in Section 8.02(a) shall survive until 30 days after the expiration of the relevant statute of limitations (giving effect to any waiver, mitigation or extension thereof).

(v) Any indemnification of a Purchaser Indemnitee pursuant to this Section 8.02 shall be effected by wire transfer or transfers of immediately available funds from the Sellers to an account or accounts designated in writing by the applicable Purchaser Indemnitee to the Sellers within 15 days after the final determination thereof.

In furtherance of the foregoing, Purchaser and each of the Companies hereby waive, from and after the Closing, to the fullest extent permitted under applicable Law, any and all rights, claims and causes of action (other than claims of, or causes of action arising from, fraud) each may have against the Sellers and their affiliates arising under, based upon or relating to this Agreement, the Acquisition and the other transactions contemplated

CLI-2060753v12

hereby, the Companies any document or certificate delivered in connection herewith, any applicable Law or otherwise (except pursuant to the indemnification provisions set forth in Article VIII and this Article IX).

(iii) Any indemnification of a Seller Indemnitee pursuant to this Section 9.03 shall be effected by wire transfer or transfers of immediately available funds from Purchaser to an account or accounts designated in writing by the applicable Seller Indemnitee to Purchaser within 15 days after the final determination thereof.

(b) Purchaser shall have no liability for indemnification pursuant to Section 9.03(a)(i)(A) with respect to Covered Losses for which indemnification is provided thereunder unless such Covered Losses exceed in the aggregate $6,500,000, in which case Purchaser shall be liable for all such Covered Losses in excess of such amount; provided, however, that in no event shall Purchaser have any liability or indemnification obligation for Covered Losses in excess of $40,000,000; provided, however that the preceding limitations shall not apply to indemnification with respect to (x) any misrepresentation of or inaccuracy in any Purchaser Fundamental Representation or (y) any claims of, or causes of action arising from, fraud.

(c) Except as otherwise specifically provided in this Agreement, the Sellers acknowledge that their sole and exclusive remedy with respect to any and all claims relating to this Agreement, the Acquisition and the other transactions contemplated

CLI-2060753v12

In furtherance of the foregoing, each of the Sellers hereby waives, from and after the Closing, to the fullest extent permitted under applicable Law, any and all rights, claims and causes of action (other than claims of, or causes of action arising from, fraud) it may have against Purchaser and its affiliates arising under, based upon or relating to this Agreement, the Acquisition and the other transactions contemplated hereby, the Companies, any document or certificate delivered in connection herewith, any applicable Law or otherwise (except pursuant to the indemnification provisions set forth in Article VIII and this Article IX.).

SECTION 9.04. Procedures. (a) Third Party Claims. In order for a person (the “Indemnified Party”) to be entitled to any indemnification provided for under Section 9.02 or 9.03 in respect of, arising out of or involving a claim made by any person against the Indemnified Party (a “Third Party Claim”), such Indemnified Party must notify the indemnifying party in writing (and in reasonable detail taking into account the information then available to the Indemnified Party) of the Third Party Claim within 10 business days after receipt by such Indemnified Party of notice of the Third Party Claim; provided, however, that failure to give such notification shall not affect the indemnification provided hereunder except to the extent the indemnifying party shall have been prejudiced as a result of such failure. Thereafter, the Indemnified Party shall deliver to the indemnifying party, as promptly as reasonably practicable and in any event within ten days after the Indemnified Party’s receipt thereof, copies of all notices and documents (including court papers) received by the Indemnified Party relating to the Third Party Claim.

(b) Assumption. If a Third Party Claim is made against an Indemnified Party, the indemnifying party shall be entitled to participate in the defense thereof and, subject to the limitations set forth in Section 9.04(c), to assume the defense thereof with counsel selected by the indemnifying party; provided, however, that (i) such counsel is not reasonably objected to by the Indemnified Party, (ii) prior to assuming control of such defense, the indemnifying party must furnish the Indemnified Party with evidence that the indemnifying party has adequate resources to defend the Third Party Claim and fulfill its indemnity obligations, if any, hereunder. In the event that the indemnifying party assumes the defense of a Third-Party Claim in accordance with this Section 9.04, the indemnifying party shall have a sixty (60) day period (the “Discovery Period”) following receipt by the indemnifying party of notice of such Third Party Claim during which the indemnifying party shall be entitled to reasonable discovery with respect to the indemnifiable nature of the claims. The indemnifying party and the Indemnified Party shall reasonably cooperate with each other with respect to such discovery. If the indemnifying party does not provide written notice to the Indemnified Party by the end of the Discovery Period that it no longer continues to assume the defense of the Third-Party Claim, the claims made in that Third-Party Claim will be conclusively established for purposes of this Agreement as within the scope of and subject to indemnification hereunder. Should the indemnifying party so elect to assume and continue the defense of a Third Party Claim in accordance with and subject to the limitations of this Section 9.04, the indemnifying party shall not be liable to the Indemnified Party for any legal expenses incurred by the Indemnified Party in connection with the defense thereof following the

CLI-2060753v12

Discovery Period. If the indemnifying party assumes such defense, the Indemnified Party shall have the right to participate in the defense thereof and to employ counsel (not reasonably objected to by the indemnifying party), at its own expense, separate from the counsel employed by the indemnifying party, it being understood that the indemnifying party shall control such defense in accordance with and subject to the limitations of this Section 9.04; provided, however that the indemnifying party shall be liable for the fees and expenses of counsel employed by the Indemnified Party (A) for any period during which the indemnifying party has not assumed the defense thereof or (B) if the Indemnified Party shall reasonably conclude, after consultation with outside legal counsel, that there is a conflict of interest between the indemnifying party and the Indemnified Party in the conduct of the defense of such claim. Each party shall reasonably cooperate, and shall cause its affiliates to reasonably cooperate in the defense or prosecution of any Third Party Claim and shall retain and provide upon reasonable request records and information that are reasonably relevant to such Third Party Claim and make employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. If the indemnifying party assumes the defense of a Third Party Claim in accordance with and subject to the limitations of this Section 9.04, the indemnifying party shall obtain the prior written consent of the Indemnified Party (such consent shall not be unreasonably withheld) before entering into any settlement of such Third Party Claim; provided, however that consent of the Indemnified Party shall not be required for any such settlement if (X) such settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such Third Party Claim and does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Party, (Y) the sole relief provided is monetary damages that are paid in full by the indemnifying party and (Z) such settlement does not permit any order, injunction or other equitable relief to be entered, directly or indirectly, against the Indemnified Party. If the indemnifying party does not assume the defense of a Third Party Claim, the Indemnified Party shall not be entitled to indemnification hereunder with respect thereto if it has admitted liability with respect to, or settled, compromised or discharged, such Third Party Claim without the indemnifying party’s prior written consent (such consent not to be unreasonably withheld).

(c) Limitations on Assumption. The indemnifying party shall not be entitled to assume or maintain control of the defense of any Third Party Claim and shall pay the fees and expenses of counsel retained by the Indemnified Party if (i) the indemnifying party does not deliver to the Indemnified Party acknowledgement of such assumption or control within 20 days of receipt of notice of the Third Party Claim pursuant to Section 9.04(a) (but subject to the right of the indemnifying party to elect not to continue to assume the defense of such claim following the Discovery Period), (ii) the Third Party Claim relates to or arises in connection with any criminal proceeding, action, indictment, allegation or investigation, (iii) the Third Party Claim seeks an injunction or equitable relief against the Indemnified Party or any of its affiliates (other than claims for injunctive or equitable relief that are ancillary to a claim for monetary damages) or (iv) the indemnifying party has failed or is failing to prosecute or defend vigorously the Third Party Claim.

CLI-2060753v12

(d) Tax Claims. For the avoidance of doubt, the procedures set forth in this Section 9.04 shall not apply with regard to Covered Loss relating to Taxes, for which indemnification provisions are set forth in Article VIII.

(e) Other Claims. In the event any Indemnified Party should have a claim against any indemnifying party under Section 9.02 or 9.03 that does not involve a Third Party Claim being asserted against or sought to be collected from such Indemnified Party, the Indemnified Party shall deliver notice of such claim with reasonable promptness to the indemnifying party. Subject to Section 9.01, the failure by any Indemnified Party so to notify the indemnifying party shall not relieve the indemnifying party from any liability that it may have to such Indemnified Party under Section 9.02 or 9.03, except to the extent that the indemnifying party demonstrates that it has been prejudiced by such failure.

(f) Mitigation. Purchaser and the 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 making commercially reasonably efforts to mitigate or resolve any such claim or liability. In the event that Purchasers or the Sellers shall fail to make such commercially reasonably efforts to mitigate or resolve any claim or liability, then notwithstanding anything else to the contrary contained herein, the other party shall not be required to indemnify any person for any Covered Losses to the extent that such Covered Losses would reasonably be expected to have been avoided if Purchaser or the Sellers, as the case may be, had made such efforts.

SECTION 9.05. No Additional Representations.

(a) Purchaser acknowledges that it and its representatives have been permitted access to the books and records, facilities, equipment, Tax Returns, Contracts, insurance policies (or summaries thereof) and other properties and assets of the Business that it and its representatives have desired or requested to see or review, and that it and its representatives have had a full opportunity to meet with the Business Employees to discuss the Business. Purchaser acknowledges that (i) none of the Sellers, the Companies or any other person has made any representation or warranty, expressed or implied, as to the Business or the accuracy or completeness of any information regarding the Business furnished or made available to Purchaser and its representatives, except as expressly set forth in this Agreement or the Seller Disclosure Letter, (ii) Purchaser has not relied on any representation or warranty from the Sellers or any other person in determining to enter into this Agreement, except as expressly set forth in this Agreement or the Seller Disclosure Letter, and (iii) none of the Sellers or any other person shall have or be subject to any liability to Purchaser or any other person resulting from the distribution to Purchaser, or Purchaser’s use of, any such information, including any information, documents or material made available to Purchaser in any “data rooms”, management presentations or in any other form in expectation of the transactions contemplated hereby. Purchaser acknowledges that, should the Closing occur, Purchaser shall acquire the Subject Shares and the Purchased Assets without any representation or warranty as to merchantability or fitness of the assets of the Business for any particular purpose, in an

CLI-2060753v12

“as is” condition and on a “where is” basis, except as otherwise expressly set forth in this Agreement or the Seller Disclosure Letter.

(b) In connection with the investigation by Purchaser of the Companies, Purchaser has received or may receive from the Companies certain projections, forward-looking statements and other forecasts and certain business plan information. Purchaser acknowledges that there are uncertainties inherent in attempting to make such estimates, projections and other forecasts and plans, that Purchaser is familiar with such uncertainties, that Purchaser is taking full responsibility for making its own evaluation of the adequacy and accuracy of all estimates, projections and other forecasts and plans so furnished to it (including the reasonableness of the assumptions underlying such estimates, projections, forecasts or plans), and that Purchaser shall have no claim against anyone with respect thereto. Accordingly, Purchaser acknowledges that neither the Companies nor any of the Sellers or Sellers Representatives, whether in an individual, corporate or any other capacity, make any representation, warranty, or other statement with respect to, and Purchaser is not relying on, such estimates, projections, forecasts or plans (including the reasonableness of the assumptions underlying such estimates, projections, forecasts or plans).

SECTION 9.06. Determination of Loss Amount.

(a) The amount of any and all Covered Losses under this Article IX will be determined net of (i) any Tax benefits actually realized by any party seeking indemnification hereunder arising from the deductibility (or amortization or capitalization or other tax benefit, etc.) of any such Covered Losses and (ii) any amounts recovered or recoverable by any party or any affiliate of a party under or pursuant to any insurance policy, title insurance policy, indemnity, reimbursement arrangement or Contract pursuant to which or under which such party or such party’s affiliates is a party or has rights.

(b) In no event will the Purchaser Indemnitees be entitled to recover or make a claim for any amounts in respect of consequential, incidental or indirect damages, lost profits, diminutions in value or punitive damages and, in particular, no “multiple of profits” or “multiple of cash flow” or other valuation methodology will be used in calculating the amount of any Covered Losses (other than for Covered Losses (i) incurred by a Purchaser Indemnitee in connection with any Third Party Claim or (ii) with respect to any misrepresentation of or inaccuracy in Section 3.15(g)). Attorney, consultant, and other professional fees and disbursements incurred by an indemnifying party in connection with this Article IX will be reasonable and based only on time actually spent, which will be charged at no more than such professional’s standard hourly rate. Notwithstanding any other provision of this Agreement to the contrary, any Covered Loss claimed hereunder will be in good faith in light of the facts then known regarding such Covered Loss. Purchaser shall have no right to assert any claim pursuant to this Article IX with respect to any Covered Loss, cause of action or other claim to the extent it is a Covered Loss, cause of action or claim with respect to which Purchaser or any of its affiliates has taken action (or caused action to be taken) to accelerate the time period in which such matter is asserted or payable for the purpose of asserting a claim for indemnification hereunder.

CLI-2060753v12

(c) No Purchaser Indemnitee will be entitled to any indemnification under this Article IX to the extent such matter (i) is taken into account in the calculation of Final Working Capital or (ii) is reasonably described in the Seller Disclosure Letter; provided that this Section 9.06(c) shall in no way limit any indemnification pursuant to Section 9.02(a)(i)(D).

SECTION 9.07. Adjustments. All payments made pursuant to Articles VIII and IX shall be treated by the parties hereto on all applicable Tax Returns as an adjustment to the Purchase Price.

SECTION 9.08. Subrogation. After any indemnification payment is made pursuant to this Article IX, the indemnifying party shall, to the extent of such payment, be subrogated to all rights (if any) of the Indemnified Party against any third party in connection with the Covered Losses to which such payment relates. Without limiting the generality of the preceding sentence, any Indemnified Party receiving an indemnification payment shall execute, upon the written request of the indemnifying party, any instrument reasonably necessary to evidence such subrogation rights.

SECTION 9.09. Environmental Indemnification.

(a) Purchaser understands and agrees that (i) each Purchaser Indemnitee’s right to indemnification under ‎Section 9.02(a)(i)(A) for breach of the representations and warranties contained in ‎Section 3.15 and under Section 9.02(a)(i)(E) for Indemnified Environmental Liabilities shall constitute its sole and exclusive remedy against the Sellers with respect to any environmental matter arising out of acts occurring or conditions existing on or prior to Closing and relating to the past or current facilities, properties or operations of the Companies and their predecessors, including any such matter arising under any Environmental Laws and (ii) no Purchaser Indemnitee will have the right to indemnification under ‎Section 9.02(a)(i)(A) for breach of the representations and warranties contained in ‎Section 3.15 (other than Section 3.15(g)) if the Covered Loss for which such right to indemnification is an Indemnified Environmental Liability. Except as set forth in this Agreement, effective at Closing, Purchaser hereby waives any right, whether arising at law or in equity, to seek contribution, cost recovery, damages, or any other recourse or remedy from the Sellers, and hereby releases the Sellers from any claim, demand or liability, in each case with respect to any environmental matter arising out of acts occurring or conditions existing on or prior to Closing and relating to the past or current facilities, properties or operations of the Companies and their predecessors. The Sellers shall have no obligation to indemnify the Purchaser Indemnitees with respect to Covered Losses arising from any Contamination to the extent identified as a result of any environmental sampling or testing after the Closing Date by or on behalf of any Purchaser Indemnitee unless such sampling or testing is (i) required by any Environmental Law (including any Environmental Law coming into effect on or after the Closing) or Governmental Entity, (ii) required by any third party that is legally entitled to do so, including Boliden, or (iii) incidental to the operation of the business consistent

CLI-2060753v12

with the historical operation of the business and would have been undertaken even in the absence of an indemnity provided hereunder, including such sampling or testing conducted in connection with changes to the operation of the business as reflected in Schedule 9.09(a) or otherwise consistent with the scope and type of historic changes to the operation of the business. The Sellers’ obligation to indemnify the Purchaser Indemnitees for any Remedial Action pursuant to this Agreement shall be limited to such Remedial Action (i) already underway as of the Closing Date; (ii) reasonably necessary to satisfy the requirements of any applicable Governmental Entity or Environmental Law in effect as of the Closing; (iii) reasonably necessary to resolve or avoid any investigation, action, claim, suit or proceeding by or before a Governmental Entity; (iv) reasonably necessary to mitigate any imminent and substantial threat to human health or the environment; or (v) reasonably necessary to comply with the terms of any contractual obligation or take advantage of a right under a contract existing as of the Closing; and then only to the extent that such Remedial Action is undertaken in a reasonably cost effective manner, assuming continued industrial use of the applicable Business Property (and industrial or non-industrial use, as applicable, of any affected groundwater, sediments, surrounding properties or other impacted areas) and employing risk-based standards and institutional controls where available and reasonably appropriate under the specific circumstances.

(b) The Sellers shall have no liability for indemnification pursuant to Section 9.02(a)(i)(E) with respect to Indemnified Environmental Liabilities unless a claim for such Indemnified Environmental Liabilities is asserted prior to the fifth year anniversary of the Closing Date.

(c) In the event the Sellers make any indemnification payments to any Purchaser Indemnitee pursuant to Section 9.02(a)(i)(A) for any breach of the representations and warranties set forth in Section 3.15 (Environmental Matters) or to Section 9.02(a)(i)(E) for Indemnified Environmental Liabilities that is reasonably determined to be a result of Contamination existing (i) at the “Leased Land” (as that term is defined in that certain lease agreement (“Site Lease”) dated October 7, 1994 by and between Outokumpu Kokkola Zinc Oy, Kokkola Chemicals Oy, Outokumpu Metals & Resources Oy and OM Group, Inc., as amended; and (ii) prior to December 11, 1991 (“Pre-1991 Contamination”), then Purchaser agrees to cause OMG Kokkola Chemicals to use reasonable good faith efforts to pursue and exhaust such remedies as are available to it pursuant to the Site Lease with respect to such ▇▇▇-▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇▇▇▇.

(i) If in connection with the foregoing OMG Kokkola Chemicals recovers any amounts pursuant to its rights under the Site Lease for damages suffered or incurred in connection with such Pre-1991 Contamination, then the Purchaser Indemnitees shall promptly reimburse the Sellers for any indemnity payments previously made to Purchaser Indemnitees by the Sellers for such ▇▇▇-▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇▇▇▇ but only up to such amounts received by OMG KokkolaChemicals under the Site Lease, net of any expenses incurred in connection with the pursuit and recovery of such amounts.

Article I
Definitions

SECTION 1.01. Definitions. The following terms, as used herein, have the following meanings:

“Cobalt Revenue” means, with respect to the Business for any period, the gross amount of revenue from sales of cobalt products for such period, in arm’s length sales by the Business, excluding (i) all amounts received from resale of cobalt metal, (ii) all by-product revenue, such as, but not limited to, copper, nickel and germanium, (iii) all metal additive revenue components of cobalt products, such as, but not limited to, nickel and manganese and (iv) all other revenue of the Business. For the avoidance of doubt, cobalt revenue from tolling, or “recycle”, of metal provided by customers and refined at Kokkola does not include any “pass-through” of metal raw material cost, and only includes the value-added and applicable premium associated with the Business’s refining and conversion of such products.

“Cobalt Revenue Coefficient” means,

with respect to the First Earn-out Year, the result of (i) the amount, if any, by which Cobalt Revenue for such Earn-out Year exceeds $420,000,000, divided by (ii) $80,000,000,

with respect to the Second Earn-out Year, the result of (i) the amount, if any, by which Cobalt Revenue for such Earn-out Year exceeds $460,000,000, divided by (ii) $80,000,000, and,

with respect to the Third Earn-out Year, the result of (i) the amount, if any, by which Cobalt Revenue for such Earn-out Year exceed $500,000,000, divided by (ii) $70,000,000;

provided that in no event shall the Cobalt Revenue Coefficient for any Earn-out Year be less than 0 or greater than 1.

“Earn-out Payment” means, with respect to a given Earn-out Year, an amount equal to (i) $36,666,667, multiplied by (ii) the Cobalt Revenue Coefficient for such Earn-out Year; provided that if the aggregate Cobalt Revenue for all three Earn-out Years is at least $1,610,000,000, then, notwithstanding the foregoing provisions of this definition, the Earn-out Payment for the Third Earn-out Year shall be an amount equal to (a) $110,000,000 less (b) the sum of the Earn-out Payments for the First Earn-out Year and the Second Earn-out Year.

“Earn-out Year” means any of (i) the First Earn-out Year, (ii) the Second Earn-out Year and (iii) the Third Earn-out Year.

“Final Cobalt Revenue” means, with respect to a given Earn-out Year, the Cobalt Revenue for such Earn-out Year (1) as shown in Purchaser’s calculation delivered pursuant to Section 2.01(a) of this Exhibit A, if no notice of disagreement with respect thereto is duly

CLI-2060753v12

delivered pursuant to Section 2.01(a) of this Exhibit A or (2) if such a notice of disagreement is delivered, (a) as agreed by Purchaser and Seller pursuant to Section 2.01(b) of this Exhibit A or (b) in the absence of such agreement, as shown in the Accounting Firm’s calculation delivered pursuant to Section 2.01(b) of this Exhibit A.

“First Earn-out Year” means the period from the beginning of the first month immediately following the Closing Date to the first anniversary of such date.

“Second Earn-out Year” means the period from the date that is the end of the First Earn-out Year to the first anniversary of such date.

“Third Earn-out Year” means the period from the date that is the end of the Second Earn-out Year to the first anniversary of such date.

ARTICLE II
Earn-out Payments and Procedures

SECTION 2.01. Calculation of Earn-out Payments. (a) As promptly as practicable, but no later than 30 days, after the end of an Earn-out Year, Purchaser will cause to be prepared and delivered to the Sellers a certificate (each, an “Earn-out Certificate”) setting forth in reasonable detail Purchaser’s calculation of Cobalt Revenue for such Earn-out Year. If the Sellers disagree with Purchaser’s calculation of Cobalt Revenue for such Earn-out Year, the Sellers may, within 30 days after delivery of the Earn-out Certificate, deliver a notice to Purchaser disagreeing with such calculation. Any such notice of disagreement shall specify those items or amounts as to which the Sellers disagree, and the Sellers shall be deemed to have agreed with all other items and amounts contained in the Earn-out Certificate. If the Sellers do not so notify Purchaser of a dispute with respect to the Earn-out Certificate within such 30-day period, the Earn-out Certificate will be final, conclusive and binding on the parties.

(b) If a notice of disagreement shall be duly delivered pursuant to Section 2.01(a), Purchaser and the Sellers shall negotiate in good faith to resolve such dispute. If Purchaser and the Sellers, notwithstanding such good faith effort, fail to resolve such dispute within 15 days after the Sellers advise Purchaser of their objections, then Purchaser and the Sellers jointly shall engage the Accounting Firm to resolve such dispute. As promptly as practicable, and in any event not more than 15 days thereafter, Purchaser and the Sellers shall each prepare and submit a presentation detailing such party’s complete statement of proposed resolution of the dispute to the Accounting Firm. As soon as practicable thereafter, Purchaser and the Sellers shall cause the Accounting Firm to choose one of the parties’ positions based solely upon the presentations by Purchaser and the Sellers. The parties shall share the expenses of the Accounting Firm equally. All determinations made by the Accounting Firm will be final, conclusive and binding on the parties.

(c) For purposes of complying with the terms set forth in this Section 2.01 of Exhibit A, each party shall cooperate with and make available to the other party and its representatives all information, records, data and working papers, and shall permit access to its facilities and personnel, as may be reasonably required in connection with the preparation and analysis of the Earn-out Certificate and the resolution of any disputes thereunder (subject to

CLI-2060753v9

reasonable confidentiality restrictions and the provision of such assurances, releases, indemnities or other agreements as accountants may customarily require in such circumstances).

SECTION 2.02 Earn-out Period Conduct. During the period beginning on the Closing Date and concluding at the end of the Third Earn-out Year, except as provided otherwise by the written consent of OMG: (i) Purchaser Guarantor shall cause the Business to only engage in arm’s length sales of cobalt products and (ii) Purchaser Guarantor shall, and shall cause its affiliates to, act in good faith and not take any action the purpose of which is avoid or lessen the payments that would otherwise be required pursuant to this Section 2.02. Subject to the preceding sentence, the parties acknowledge and agree that OMG Kokkola Chemicals shall have complete discretion with respect to the marketing and pricing of all of its products and services and, following the Closing, except as otherwise provided in this Section 2.02, OMG Kokkola Chemicals shall have the right to operate the Business as it sees fit.

SECTION 2.03. Distribution of Earn-out Payments. (a) As promptly as practicable, but no later than five business days, after the determination of Final Cobalt Revenue for a given Earn-out Year, Purchaser shall pay, or shall cause to be paid, to the Sellers the Earn-out Payment for such Earn-out Year; provided that such amount shall be reduced in accordance with Article IX for any claims for indemnification by Purchaser pursuant to Article IX of the Agreement that are finally determined (either by agreement between the parties or pursuant to a final and nonappealable judgment of a court of competent jurisdiction) as of the last day of the given Earn-out Year and that have not otherwise been satisfied. Each Earn-out Payment shall be paid by or on behalf of Purchaser in immediately available funds by wire transfer to an account of the Sellers with a bank designated by the Sellers, by notice to Purchaser, which notice shall be delivered not later than two Business Days following the determination of Final Cobalt Revenue for a given Earn-out Year (or if not so designated, then by certified or official bank check payable in immediately available funds to the order of Seller in such amount).

(b) For the avoidance of doubt, the maximum aggregate amount of Earn-Out Payments Purchaser and its affiliates shall be obligated to pay pursuant to this Exhibit A shall be $110,000,000.

(c) The Sellers’ right to receive any Earn-out Payment shall not be evidenced by any form of certificate or instrument and does not represent any ownership or equity interest in Purchaser, the Business, the Companies, the Subsidiaries or any of their respective affiliates and does not entitle any Seller to voting rights or rights to dividend payments.
