Purchaser acknowledges that the information being provided to it in connection with the Acquisition and the consummation of the other transactions contemplated hereby is subject to the terms of a Confidentiality Agreement between Purchaser and OMG dated October 28, 2005, as amended (the “Confidentiality Agreement”), the terms of which are incorporated herein by reference. Effective upon, and only upon, the Closing, the Confidentiality Agreement shall terminate with respect to information relating solely to the Companies, Cawse, MPI and Talvivaara; provided, however, that Purchaser acknowledges that its obligations of confidentiality and non-disclosure with respect to any and all other information provided to it by OMG or any OMG Representative exclusively relating to OMG or any of its affiliates (other than the Companies, Cawse, MPI and Talvivaara), including information of OMG and its affiliates comprising battery technology, mixed metal precursor technology and spherical nickel hydroxide technology, shall continue to remain confidential and shall not be used or disclosed by Purchaser or any of its affiliates until the earlier of: (i) the eighth anniversary of the Closing Date; and (ii) such time as the relevant information is no longer Confidential Information as such term is defined in the Confidentiality Agreement.

SECTION 6.05. Further Assurances; Commercially Reasonable Efforts.

(a) Purchaser, OMG and the Sellers will use their commercially reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, and assist and cooperate with the other parties to this Agreement in doing, all things necessary or desirable under applicable Law to consummate, in the most expeditious manner practicable, the transactions contemplated by this Agreement.

(b) Purchaser, OMG and the Sellers will use their commercially reasonable efforts to:

- 30 -

(i) prepare, as soon as practicable, all filings and other presentations in connection with seeking any Required Regulatory Approval, exemption or other authorization from any Governmental Entity necessary to consummate the transactions contemplated by this Agreement;

(ii) prosecute such filings and other presentations with diligence; and

(iii) oppose any objections to, appeals from or petitions to reconsider or reopen any such approval by persons not party to this Agreement.

Purchaser, OMG and the Sellers will use their commercially reasonable efforts to facilitate obtaining any final order or orders approving the transactions contemplated by this Agreement, or to remove any impediment to the consummation of the transactions contemplated hereby. Purchaser, OMG and the Sellers will use their commercially reasonable efforts to furnish all information in connection with the approvals of or filings with regard to the Required Regulatory Approvals with any Governmental Entity and will promptly cooperate with and furnish information in connection with any such requirements imposed upon Purchaser or any of its affiliates in connection with this Agreement and the transactions contemplated hereby. Subject to Section 6.05(c), Purchaser, OMG and the Sellers will use their commercially reasonable efforts to obtain any Required Regulatory Approval, or any exemption thereto, and to remove any impediment imposed by any Governmental Entity to allow the consummation of the transactions contemplated hereby. Except as set forth in this Agreement, no party or any of its affiliates shall have any liability for the failure to obtain any Required Regulatory Approval or other consent, approval or authorization in connection with the transactions contemplated by this Agreement. Purchaser, OMG and the Sellers will each advise the other party promptly of any material communication received by such party or any of its affiliates from the European Commission (the “EC”), the Treasurer of the Commonwealth of Australia, any state attorney general or any other Governmental Entity regarding any of the transactions contemplated by this Agreement, and of any understandings, undertakings or agreements (oral or written) such party proposes to make or enter into with the EC, the Treasurer of the Commonwealth of Australia, any state attorney general or any other Governmental Entity in connection with the transactions contemplated hereby. None of the Sellers, OMG or Purchaser will participate independently in any meeting with any Governmental Entity in respect of any findings or inquiry in connection with the transactions contemplated hereby without giving the other parties prior written notice of the meeting and the opportunity to attend and/or participate, in each case, unless prohibited by the Governmental Entity. The Sellers, OMG and Purchaser will consult and cooperate with one another in connection with any information or proposals submitted in connection with Proceedings under or relating to the ECMR in connection with the transactions contemplated hereby.

(c) In furtherance and not in limitation of the provisions set forth in Section 6.05(b), each of the Sellers, OMG and Purchaser shall as promptly as practicable, following the execution and delivery of this Agreement, file with the EC the formal notification of the Acquisition required for the transactions contemplated hereby and any supplemental information requested in connection therewith pursuant to the ECMR. Any such notification and report form and supplemental information shall be in substantial compliance with the requirements of the ECMR. Each of the Sellers, OMG and Purchaser shall furnish to the other such necessary information

- 31 -

and reasonable assistance as the other may request in connection with its preparation of any filing or submission that is necessary under the ECMR. Each party shall use its commercially reasonable efforts to obtain any clearance required under the ECMR for the consummation of the transactions contemplated by this Agreement. In the event any Governmental Entity requests any Contract amendments, divestitures, licenses, or hold separate or similar agreements with respect to Contracts, assets or conduct of business arrangements (collectively, “Regulatory Concessions”) as a condition to obtaining any approval from any Governmental Entity for any reason in order to consummate and make effective the transactions contemplated by this Agreement by the Sellers or Purchaser or their respective affiliates, the Sellers and Purchaser agree to promptly meet and negotiate in good faith in an attempt to agree reasonable amendments to the terms of this Agreement or the Related Documents that preserve as nearly as possible the respective burdens and benefits of such agreements and achieve, or obviate the need for, the requested Regulatory Concession and permit the Closing to proceed.

(d) Prior to the Closing, each party shall, and shall cause its affiliates to, use commercially reasonable efforts (at its own expense) to obtain, and to cooperate in obtaining, all consents from third-parties necessary or appropriate to permit the consummation of the Acquisition; provided, however, that the parties shall not be required to pay or commit to pay any amount (other than a nominal amount) to (or incur any obligation in favor of) any person from whom any such consent may be required (other than nominal filing or application fees). Purchaser acknowledges that certain consents and waivers with respect to the transactions contemplated by this Agreement may be required from parties to the Contracts listed in the Schedules and that such consents and waivers have not been obtained. Except as provided in this Section 6.05 and Section 7.02(c), no Seller or any of its affiliates shall have any liability whatsoever to Purchaser arising out of or relating to the failure to obtain any consents or waivers that may be required in connection with the transactions contemplated by this Agreement or because of the termination of any Contract as a result thereof. Except as set forth in this Section 6.05 and Section 7.02(c), Purchaser acknowledges that no representation, warranty or covenant of OMG or the Sellers contained herein shall be breached or deemed breached, and no condition shall be deemed not satisfied, as a result of (i) the failure to obtain any such consent or waiver, or (ii) any such termination.

(e) Neither Purchaser nor the Sellers shall challenge any of the transactions contemplated by this Agreement before any Governmental Entity. Any party may (but shall not be obligated to) agree to any request of a Governmental Entity to make a change to any of the terms and provisions of this Agreement or any Related Document in order to obtain any Required Regulatory Approval, provided that such term or provision is exclusively to that party’s benefit and the relevant change does not adversely affect the interests of the other parties hereto or thereto.

SECTION 6.06. Expenses; Transfer Taxes.

(a) Whether or not the Closing takes place, and except as set forth in this Section 6.06 and Articles IX and X, all costs and expenses (including, without limitation, attorneys’ and advisors’ fees) incurred in connection with this Agreement, the Related Documents and the transactions contemplated hereby and thereby shall be paid by the party incurring such expense, including all costs and expenses incurred pursuant to Section 1.04; provided, however, that all

- 32 -

filing fees in connection with the Required Regulatory Approvals, exemptions or other authorization from any Governmental Entity necessary to consummate the transactions contemplated by this Agreement, shall be paid by the party liable under applicable Law for such fees and in the absence of such liability being established by applicable Law shall be borne one-half by OMG and one-half by Purchaser; and provided, further, that in the event of any litigation under this Agreement or the Related Documents, including, without limitation, Articles IX and X, the prevailing party’s costs and expenses (including reasonable attorneys’ and advisors’ fees, and costs and expenses incurred in collecting such fees) shall be paid by the non-prevailing party or parties to such litigation. In determining whether, or the extent to which, a party is the prevailing party for purposes of the preceding sentence, the court shall consider the totality of the positions of the parties in litigation and may determine that one party has prevailed as to the matters in dispute, taken as a whole, or, if the disputes are determined to be separate and discrete, shall apportion costs and expenses based on which party has prevailed on each issue presented.

(b) All Transfer Taxes applicable to the transfer of the Subject Shares and the Talvivaara Shares, including any such Taxes arising as a result of any deemed or effective transfer of the capital stock of Cawse as a result of the Acquisition, shall be borne by the party that is liable pursuant to applicable Law for such Transfer Taxes and in the absence of such liability being established by applicable Law shall be borne one-half by Purchaser and one-half by OMG. Each party shall use reasonable efforts to avail itself of any available exemptions from any such Transfer Taxes, and to cooperate with the other parties in providing any information and documentation that may be necessary to obtain such exemptions.

SECTION 6.07. Publicity. From the date hereof through the Closing Date, no public release or announcement concerning the transactions contemplated hereby shall be issued by any party without the prior consent of the other parties (which consent shall not be unreasonably withheld or delayed), except as such release or announcement may be required by applicable Law or the rules or regulations of any securities exchange, in which case the party required to make the release or announcement shall allow the other party reasonable time to comment on such release or announcement in advance of such issuance; provided, however, that each of the Sellers, OMG and Purchaser may make internal announcements to their respective employees that are consistent with the parties’ prior public disclosures regarding the transactions contemplated hereby after reasonable prior notice to and consultation with the other party.

SECTION 6.08. Names, Trademarks and Logos Following Closing.

(a) As soon as reasonably practicable following the Closing, Purchaser shall amend or terminate any certificate of assumed name or “doing business as” filings so as to eliminate its or its affiliates’ right to use the Names, Trademarks and Logos, or any name, trademark or logo that, in the reasonable judgment of the Sellers, is similar to the Names, Trademarks and Logos, and Purchaser and its affiliates shall not thereafter use the Names, Trademarks or Logos or other names, trademarks or logos confusingly similar thereto, except as provided in this Section 6.08. Purchaser shall also amend the organizational documents of the Companies and Cawse to change the names thereof to a name not including or similar to any of the Names, Trademarks and Logos and shall cease the use of all Internet domain names (including the related URLs) which use the Names, Trademarks and Logos. “Names, Trademarks and Logos” means the names, trademarks and logos listed in Schedule 6.08.

- 33 -

(b) After the Closing, Purchaser and its affiliates shall have the right to (i) sell existing inventory and (ii) use existing packaging, labeling, containers, stationery, business forms, supplies, advertising and promotional materials and any similar materials bearing the Names, Trademarks and Logos for sixty (60) days following the Closing; provided, however, that neither Purchaser nor any of its affiliates shall take any action that could reasonably be expected to impair the value of the Names, Trademarks and Logos; provided further, however, that when using the items listed in clause (ii) above in the context of entering into or conducting contractual relationships, Purchaser shall make clear to all other applicable parties that Purchaser, rather than the Sellers or their affiliates, is the party entering into or conducting the contractual relationship; provided further, however, that personnel of Purchaser or its affiliates using the above items shall not, and shall have no authority to, hold themselves out as officers, employees or agents of the Sellers or any affiliate of any of the Sellers. Purchaser and its affiliates shall comply with all applicable Laws in any use of packaging or labeling containing the Names, Trademarks and Logos.

(c) Subject to the foregoing, Purchaser shall use commercially reasonable efforts to minimize its use of the Names, Trademarks and Logos, and, in any event, shall cease using the Names, Trademarks or Logos on fixed assets as soon as practicable and in any event within sixty (60) days after the Closing.

SECTION 6.09. Consents of Third-Parties.

(a) Notwithstanding anything in this Agreement to the contrary, this Agreement shall not constitute an agreement to assign any Assigned Contract or any claim or right or any benefit arising under or resulting from such Assigned Contract if an attempted assignment thereof, without the consent of a third-party, would constitute a breach or other contravention of the rights of such third-party, would be ineffective with respect to any party to an agreement concerning such Assigned Contract, or would in any way adversely affect the rights of the Companies or their affiliates or, upon transfer, Purchaser under such Assigned Contract. If any transfer or assignment by the Companies or their affiliates to, or any assumption by Purchaser of, any interest in, or liability, obligation or commitment under, any Assigned Contract requires the consent of a third-party, then such assignment or assumption shall be made subject to such consent being obtained.

(b) If any such consent is not obtained prior to the Closing, the Sellers and Purchaser shall cooperate (at their own expense) in any lawful and reasonable arrangement proposed by Purchaser under which Purchaser shall obtain the economic claims, rights and benefits under the Assigned Contract with respect to which the consent has not been obtained in accordance with this Agreement. Such reasonable arrangement may include (i) the subcontracting, sublicensing or subleasing to Purchaser of any and all rights of the Sellers against the other party to such third-party Contract arising out of a breach or cancellation thereof by the other party, and (ii) the enforcement by the Sellers of such rights.

- 34 -

SECTION 6.11. Undertakings by OMG.

OMG hereby agrees to the undertakings set forth in Schedule 6.11.

SECTION 6.12. No Further Financial Obligations. Purchaser acknowledges that in the course of conduct by the Companies and Cawse of their respective businesses, OMG and its affiliates (collectively, but excluding the Companies and Cawse, the “OMG Entities”) entered into various arrangements (i) in which guarantees were issued by the OMG Entities and (ii) in which the OMG Entities are the primary obligors on other agreements, in any such case to support or facilitate business transactions or programs of the Companies and Cawse. The financing arrangements referred to in the foregoing clauses (i) and (ii) are hereinafter referred to as the “Guarantees” and copies of such Guarantees are set forth on Schedule 6.12. It is understood that the Guarantees shall not continue after the Closing and, at the Closing, Purchaser shall pay to OMG, an amount in U.S. dollars equal to any and all deposits, bonds and similar items provided by the OMG Entities in respect of the Guarantees. Purchaser agrees that Purchaser shall use its commercially reasonable efforts to obtain replacement Guarantees which will be in effect at the Closing or, in the case of Guarantees described in the foregoing clause (ii), will either terminate the business transactions or programs of the Companies and Cawse supported or facilitated by such Guarantees or 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 OMG Entities from and against any and all losses incurred by the OMG Entities relating to the Guarantees.

SECTION 6.13. Environmental Audit.

(a) Promptly following execution of this Agreement Purchaser shall cause each of Pöyry Environment Oy (the “HNO Environmental Consultant”) and URS Australia Pty Ltd. (the “Cawse Environmental Consultant”), or such other consultants as Purchaser may determine in its discretion, to perform an environmental site assessment (including, if appropriate, sampling and analysis) and environmental compliance audit (the “Environmental Audit”), the scope and terms of which are set forth on Schedule 6.13, to review and verify the existing environmental condition of the Business Property and any Releases of Hazardous Materials therefrom of each of HNO and Cawse, respectively, (the “Audited Sites”), and compliance with existing Environmental Laws regarding soil, air, water and wastewater discharges, perched water and groundwater as at or before the Closing Date at the Audited Sites, such review and the reports thereon (each an “Environmental Report” and together the “Environmental Reports”) expected to be completed and delivered to the Sellers and Purchaser within one hundred and twenty (120) days of the date hereof. The Environmental Reports shall describe the Remediation necessary to meet any and all clean up or Remediation requirements of the Audited Sites under existing Environmental Laws as at or before the Closing Date based upon the continuing use of such property in a manner substantially similar to its use at the time of the Environmental Audit. Following receipt by the Sellers and Purchaser of the Environmental Reports, the Sellers and Purchaser shall have thirty (30) days within which to review each Environmental Report and notify the appropriate Environmental Consultant, and the other parties hereto of any questions, comments or objections to such Environmental Report. Any changes to an Environmental Report made in response to such questions, comments or objections shall be in the sole discretion

- 35 -

of the appropriate Environmental Consultant, and in any case shall be made within forty-five (45) days of the delivery of the initial Environmental Report of such Environmental Consultant. From the date of this Agreement through the Closing Date, the Sellers shall allow Purchaser and its representatives and consultants (including, the HNO Environmental Consultant and the Cawse Environmental Consultant) reasonable access to the Audited Sites and the employees of the Sellers, Cawse and the Companies for purposes of conducting the Environmental Audit and verifying and reviewing the Environmental Reports; provided, however, that, in conducting the Environmental Audit and verifying and reviewing the Environmental Reports, Purchaser and its representatives and consultants shall not materially disrupt the business conducted at such Audited Site. The Sellers and Purchaser acknowledge that each final Environmental Report will create a rebuttable presumption as to the existing environmental condition of the Audited Sites for purposes of the representations and warranties contained in this Agreement. The costs incurred in performing the Environmental Audit shall be borne by Purchaser. Any costs incurred verifying and reviewing the Environmental Reports, shall be borne by the party incurring such costs.

(b) Neither Purchaser nor the Sellers will disclose the Environmental Reports to any Governmental Entity or third party in the absence of an affirmative legal obligation and unless such disclosure to a third party (other than a Governmental Entity) is subject to a confidentiality agreement.

(c) To the extent that the Environmental Audit reveals a violation of existing Environmental Laws as at or before the Closing Date or the presence or Release of Hazardous Materials at, on, under or from an Audited Site that requires clean up or Remediation under applicable existing Environmental Laws as at or before the Closing Date (“Recognized Environmental Conditions”), the Sellers shall, promptly following finalization of the Environmental Audits, remedy any such violation or perform Remediation of such Recognized Environmental Condition at their sole cost and expense; provided, however, that, in the remedy of any such violation or performance of any such Remediation of such Recognized Environmental Condition, the Sellers and their representative and consultants shall not materially disrupt the business conducted at such Audited Site. The Sellers will direct and control such Remediation and shall cause any Remediation under this Section 6.13 to be performed in accordance with and to the extent required pursuant to existing Environmental Laws applicable to the Remediation and taking into account the continuing use of such property in a manner substantially similar to its use at the time of the Environmental Audit and in a good, safe and workmanlike manner. In performing a Remediation the Sellers shall: (i) provide written notification to Purchaser, to the extent practical, that it intends to implement Remediation prior to commencing any such Remediation; (ii) select a qualified and reputable consultant to oversee the Remediation, subject to the approval of Purchaser, whose approval shall not be unreasonably withheld; (iii) provide Purchaser with a reasonable opportunity to comment in advance upon any material written communications, filings, reports, correspondence or other writings given to any Governmental Entity in connection with such Remediation and consider timely provided comments in good faith; (iv) to the extent practical, provide Purchaser with a reasonable opportunity to participate in any meetings with any Governmental Entity regarding the Remediation at Purchaser’s sole cost and expense; (v) comply with applicable Laws; (vi) minimize costs in conducting any Remediation; (vii) employ cost-effective Remediation methods that are commercially reasonable under the circumstances including, without limitation, the use

- 36 -

of risk assessments, institutional controls and Remediation standards based on the industrial use of such property to the extent commercially reasonable; (viii) if the Remediation is before the Closing Date, allow Purchaser or their agents reasonable access to the relevant Business Property for purposes of observing the Remediation so long as Purchaser and its agents do not interfere with the Remediation or the operation of the applicable business; (ix) keep Purchaser reasonably informed of the progress of any such Remediation and the schedule for completing such Remediation; (x) within five (5) business days of receipt, use commercially reasonable efforts to provide to Purchaser copies of all material written communications, filings, reports, correspondence or other writings, photographs or materials received from any person (including any Governmental Entity) in connection with any such Remediation; and (xi) use commercially reasonable efforts to preserve any rights Purchaser may have against insurers or other third parties.

(d) Purchaser shall permit the Sellers and their representatives and consultants access to the applicable Business Property for the purpose of performing the Remediation, so long as the Sellers use, and cause their representatives and consultants to use, commercially reasonable efforts to minimize interference with the applicable business. Following completion of any Remediation performed by the Sellers, the Sellers shall promptly return the Business Property to substantially the same condition in which it existed prior to the commencement of the Remediation (other than with respect to the presence of Hazardous Materials).

(e) Notwithstanding anything to the contrary herein, the Sellers shall not be obligated to pay any costs under Section 10.02(a)(i)(E) that arise due to any material change in the use of any Business Property as operated by Purchaser or its affiliates from and after the Closing Date.

(f) The overall cap on Covered Losses set forth in Section 10.02(c)(iv) of this Agreement shall be reduced dollar for dollar by the corresponding expenditure incurred by the Sellers in carrying out any Remediation pursuant to this Section 6.13. Any expenditure incurred by the Sellers in carrying out any Remediation pursuant to this Section 6.13 shall not be included in calculating whether the threshold for indemnifying for Covered Losses set forth in Section 10.02(b) has been met.

SECTION 6.14. Talvivaara Investment Pre-Closing.

(a) Immediately following the execution of this Agreement, OMG Finland shall, and the Sellers shall cause OMG Finland to:

(i) transfer the Additional Talvivaara Interest to HNO; and

(ii) promptly notify other shareholders of Talvivaara of the proposed transfer of the Talvivaara Shares to Purchaser hereunder in accordance with the transfer notice procedures and requirements in the Shareholders Agreement and the Articles of Association of Talvivaara (the “Talvivaara Transfer Procedures”), and (1) first seek a waiver of the Talvivaara Transfer Procedures and (2) if the shareholders do not waive the Talvivaara Transfer Procedures offer the Talvivaara Shares to the shareholders of Talvivaara in accordance with the Talvivaara Transfer Procedures.

- 37 -

(b) In the event that the Talvivaara Shares are not transferred to Purchaser or Purchaser’s Designees at the Closing pursuant to Section 1.01(b)(ii), from the Closing Date OMG Finland shall, and the Sellers shall cause OMG Finland to use all commercially reasonable efforts to seek the consents and follow the Talvivaara Transfer Procedures as required in clause (a)(ii) above. If such consents are obtained or if the Talvivaara shareholders do not exercise the Right of First Refusal, OMG Finland shall transfer the Talvivaara Shares to Purchaser or Purchaser’s Designees and deliver to Purchaser a written certification of an authorized officer of OMG Finland that the representations and warranties in Section 3.04 of this Agreement with respect to the Talvivaara Shares are true and correct as of the date of such transfer. Simultaneously with the transfer, if any, of the Talvivaara Shares to Purchaser or Purchaser’s Designees pursuant to this Section 6.14(b), NN, Purchaser or Purchaser’s Designees shall pay to OMG Finland an amount equal to US$8.3 million as the purchase price for the Talvivaara Shares.

SECTION 6.15. Employee Matters.

At the Closing, Purchaser shall make or cause an affiliate to make offers of employment to each of the individuals identified in Schedule 6.15 (the “Transferred Employees”). Such employment offers shall contain terms and conditions, including compensation and benefits, that are no less favorable in the aggregate than those applicable to such Transferred Employees immediately prior to the Closing. Purchaser or its affiliate, as applicable, shall give Transferred Employees full credit for purposes of eligibility, vesting and benefit accruals under the Employee Plans or other comparable benefit plans in which such Transferred Employee participated to the same extent recognized under the Employee Plans or other comparable benefit plans, as applicable, immediately prior to the Closing.

SECTION 6.16. Additional Agreements. Between the date hereof and the Closing Date the Sellers and Purchaser will negotiate in good faith to agree to: (a) commercially reasonable terms of the agreements listed on Schedule 6.16, each of which (if agreed) will be executed and delivered at Closing; and (b) the terms of any and all services reasonably requested by Purchaser to be provided under the Transition Services Agreement; provided, however, that the Sellers may refuse to provide any service that was not being provided to HNO as of the date of this Agreement.

TAX MATTERS

SECTION 9.01. Tax Matters.

(a) Tax Sharing Agreements. The Sellers shall cause the provisions of any Tax sharing agreement or arrangement between the Sellers or any of their affiliates (excluding the Companies, Cawse, MPI and Talvivaara), and the Companies, Cawse, MPI or Talvivaara, 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 or arrangement.

(b) Apportionment. All Taxes and Tax liabilities with respect to the income, property or operations of the Companies, Cawse, MPI or Talvivaara 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 (1) based upon or related to income, receipts, capital or net worth (but not including sales and compensating use Taxes), or (2) 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 6.06(b)), such Taxes shall be deemed equal to the amount which would be payable if the Tax year ended with the Closing Date; and (B) in the case of Taxes (other than those Taxes in the preceding clause (A)) imposed on a periodic basis with respect to the Companies and Cawse, 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.

(c) Subject to Section 9.02(a), the Sellers shall be liable for all Taxes attributable to a Pre-Closing Tax Period but only to the extent that the sum of such Taxes exceeds the aggregate accruals or reserves for such Taxes on the Cawse Closing Statement or the HNO Closing Statement (excluding any deferred Tax assets or liabilities that reflect differences between the financial statement carrying value of assets and liabilities and their Tax bases). Subject to Section 9.02(a), Purchaser, the Companies and Cawse shall be liable for (x) all Taxes attributable to any Post-Closing Tax Period and (y) all Taxes attributable to any Pre-Closing Tax Period to the extent that the sum of such Taxes does not exceed the aggregate accruals or reserves for such Taxes on the Cawse Closing Statement or the HNO Closing Statement (excluding any deferred Tax assets or liabilities that reflect differences between the financial statement carrying value of assets and liabilities and their Tax bases).

- 42 -

(d) Return Filings.

(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 Competent Authority all necessary Tax Returns of or which include or relate to the Companies or Cawse for Pre-Closing Tax Periods that are required to be filed (including extensions) on or prior to the Closing Date. The Sellers shall pay or shall cause to be paid any and all Taxes due with respect to such Tax Returns.

(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 Competent Authority all consolidated, combined or unitary Tax Returns of the Sellers that include or relate to the Companies or Cawse 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. 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 9.01(d)(ii).

(iii) For any Straddle Period of either of the Companies or Cawse, Purchaser or Purchaser’s Designees shall prepare and timely file (including extensions), or cause to be prepared and timely filed (including extensions), in proper form with the appropriate Competent Authority all Tax Returns required to be filed. Purchaser shall pay or cause to be paid any and all Taxes 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 on the Cawse Closing Statement or the HNO Closing Statement (excluding any deferred Tax assets or liabilities that reflect differences between the financial statement carrying value of assets and liabilities and their Tax bases). If the sum of all Taxes due with respect to all Pre-Closing Tax Periods exceeds the aggregate accruals or reserves for Taxes for any Pre-Closing Tax Period on the Cawse Closing Statement or the HNO Closing Statement (excluding any deferred Tax assets or liabilities that reflect differences between the financial statement carrying value of assets and liabilities and their Tax bases), 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 such accruals or reserves at least thirty (30) business days before either of the Companies or Cawse files such Tax Return.

(iv) Purchaser shall prepare and file, or shall cause one or more of the Companies and Cawse to prepare and file, in proper form with the appropriate Competent Authority all Tax Returns of or that include the Companies or Cawse for which the Sellers are not responsible pursuant to Section 9.01(d)(i) and Section 9.01(d)(ii). Purchaser shall pay or cause to be paid any and all Taxes due with respect to such Tax Returns (subject to the apportionment of Tax liabilities contemplated in Section 9.01(b)).

(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 shall and Purchaser or its affiliates shall, at the Sellers’ direction, cause any Company or Cawse to

- 43 -

(A) take all steps as are or may be reasonably necessary, including the filing of elections or returns with applicable Competent Authorities, to cause such period to end on the Closing Date or (B) if clause (A) is inapplicable, report the operations of the Company or Cawse 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. If the aggregate accruals or reserves for Taxes for Pre-Closing Tax Periods on the Cawse Closing Statement or the HNO Closing Statement exceeds the sum of the portion of all Taxes actually paid in connection with the Tax Returns for all Straddle Periods that are allocable to Pre-Closing Tax Periods pursuant to Section 9.01(b), then Purchaser shall pay an amount equal to such excess to the Seller within thirty (30) business days after the date on which the last such Tax Return for a Straddle Period is filed.

(e) Cooperation. In connection with the preparation of Tax Returns, audit examinations, and any Proceedings relating to the Tax liabilities imposed on or relating to the Sellers, the Companies or Cawse for all Pre-Closing Tax Periods and any Straddle Periods, Purchaser, the Companies and Cawse 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 Competent Authorities as to the imposition of Taxes. The Companies and Cawse and the Sellers agree (A) to retain all books and records with respect to Tax matters pertinent to the Companies and Cawse relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations (and to the extent notified by Purchaser or the Sellers, extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any Competent Authority, and (B) to give the other party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other party so requests, the Companies and Cawse and the Sellers, as the case may be, shall allow the other party to take possession of such books and records. Any information obtained under this Section 9.01(e) 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.

(f) Refunds and Credits. Purchaser shall pay or cause to be paid to the Sellers any Tax refunds or credits (except to the extent reflected on the Cawse Closing Statement or the HNO Closing Statement or due as the result of utilizing net carried forward operating or capital losses) attributable to any Pre-Closing Tax Period received by or credited to Purchaser, a Company or Cawse, net of any direct costs attributable to receipt of such refund or credit, including Taxes payable with respect to such refund, within ten (10) business days after the receipt of such refund or the realization of such credit. All refunds 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 or Cawse), the Sellers shall pay or cause to be paid an amount equal to such refund or credit to Purchaser within ten (10) business days after the receipt of such refund or the realization of such credit. At the Sellers’ request, Purchaser and the Companies and Cawse 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 the Sellers’

- 44 -

expense. Purchaser shall permit the Sellers to control the prosecution of any refund claim attributable to any Pre-Closing Tax Period 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 or Cawse with respect to such refund claim.

(g) Allocation. Each of the Sellers and Purchaser agree to allocate the Purchase Price among the Subject Shares and the Talvivaara Shares as set forth in Schedule 9.01(g) (the “Allocation”). The Allocation shall be adjusted to reflect any adjustments made pursuant to Section 1.01(b), Section 1.04 and Articles IX and X. Except for adjustments for the parties’ transaction costs, the Sellers and Purchaser shall report the sale and purchase of the Subject Shares and the Talvivaara Shares in accordance with the Allocation on all relevant Tax Returns and shall not take any position inconsistent with such Allocation unless required by applicable Law. Neither Purchaser nor the Sellers will disclose the Allocation to any Governmental Entity or third party in the absence of an affirmative legal obligation and unless disclosure to a third party (other than a Governmental Entity) is subject to a confidentiality agreement; provided, however, that the Sellers and Purchaser shall be permitted to disclose the Allocation to any Competent Authority on any required Tax Returns and as otherwise required by Law.

SECTION 9.02. Tax Indemnification.

(a) From and after the Closing, the Sellers shall jointly and severally indemnify Purchaser, its affiliates (including the Companies, Cawse, MPI and Talvivaara) and each of their respective officers, directors, employees, stockholders, agents and representatives (the “Purchaser Indemnitees”) against and hold them harmless from (i) all liability for Taxes of the Companies and Cawse or any affiliated group of which either of the Company or Cawse has ever been a member for the Pre-Closing Tax Period to the extent that the sum of all such Taxes exceeds the aggregate accruals or reserves for Taxes for Pre-Closing Tax Periods on the Cawse Closing Statement or the HNO Closing Statement (excluding any deferred Tax assets or liabilities that reflect timing differences between the financial statement carrying value of assets and liabilities and their Tax bases) and (ii) all liability for Taxes of the Sellers or any other corporation which is or has been affiliated with the Sellers (other than either of the Companies or Cawse), and (iii) any and all Taxes of any person (other than the Companies or Cawse) imposed on the Companies or Cawse as a transferee or successor, by Contract or pursuant to any Law, which Taxes relate to an event or transaction occurring before the Closing. 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, Cawse, MPI or Talvivaara), or any transferee of Purchaser or any of its affiliates (other than any such action expressly required by applicable Law or by this Agreement) or attributable to a breach by Purchaser of its obligations under this Agreement.

(b) From and after the Closing, Purchaser shall indemnify the Sellers, their affiliates (excluding the Companies, Cawse, MPI and Talvivaara) and each of the respective officers, directors, employees, stockholders, agents and representatives (the “Seller Indemnitees”) and hold them harmless from (i) all liability for Taxes of the Companies and Cawse for any Post-Closing Tax Period, (ii) all liability for Taxes of the Companies and Cawse for any Pre-Closing Tax Period but only to the extent that the sum of such Taxes does not exceed the aggregate accruals or reserves for Taxes for Pre-Closing Tax Periods on the Cawse Closing Statement or

- 45 -

the HNO Closing Statement (excluding any deferred Tax assets or liabilities that reflect differences between the financial statement carrying value of assets and liabilities and their Tax bases) and (iii) all liability for Taxes attributable to any action taken after the Closing by Purchaser, any of its affiliates (including the Companies, Cawse, MPI or Talvivaara), or any transferee of Purchaser or any of its affiliates (other than any such action expressly required by applicable Law or by this Agreement) or attributable to a breach by Purchaser of its obligations under this Agreement.

(i) If a claim shall be made by any Competent Authority, which, if successful, might result in an indemnity payment to any Purchaser Indemnitee pursuant to this Section 9.02, Purchaser shall notify promptly the Sellers in writing of such claim (a “Tax Claim”). The failure of Purchaser to give such notice shall not relieve the Sellers of their indemnification obligations under this Agreement, except to the extent the Sellers are prejudiced by such failure to give such notice.

(ii) With respect to any Tax Claim relating solely to Taxes of either of the Companies or Cawse for a Pre-Closing Tax Period, the Sellers shall control all Proceedings taken in connection with such Tax Claim (including selection of counsel) and, without limiting the foregoing, may in its sole discretion pursue or forego any and all administrative appeals, Proceedings, hearings and conferences with any Competent Authority with respect thereto, and may, in its sole discretion, either pay the Tax claimed and xxx for a refund where applicable Law permits such refund suits or contest the Tax Claim in any permissible manner. With respect to any Tax Claim relating to Taxes of either of the Companies or Cawse 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 be anticipated reasonably 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, which consent shall not be unreasonably withheld or delayed. Neither party shall settle a Tax Claim relating solely to Taxes of either of the Companies or Cawse for a Straddle Period without the other party’s prior written consent, which consent shall not be unreasonably withheld or delayed.

SECTION 10.04. Procedures.

(a) Third-Party Claims. In order for a person (the “indemnified party”) to be entitled to any indemnification provided for under Section 10.02 or 10.03 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) of the Third-Party Claim within ten (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 (although the indemnifying party shall not be liable for any expenses incurred during the period in which the indemnified party failed to give such notice). Thereafter, the indemnified party shall deliver to the indemnifying party, within five (5) business 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.

- 50 -

(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, if it so chooses, to assume the defense thereof with counsel selected by the indemnifying party, who shall consent to such counsel unless it has reasonable objections thereto. Should the indemnifying party so elect to assume the defense of a Third-Party Claim and the indemnified party consents to the chosen counsel, then:

(i) the indemnifying party shall not be liable to the indemnified party for any legal expenses subsequently incurred by the indemnified party in connection with the defense thereof;

(ii) the indemnified party shall have the right to participate in the defense thereof and to employ counsel (not to be unreasonably 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; and

(iii) all the indemnified parties shall cooperate in the defense or prosecution thereof. Such cooperation shall include the retention and (upon the indemnifying party’s request) the provision to the indemnifying party of records and information that are reasonably relevant to such Third-Party Claim, and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder.

The indemnifying party shall be liable for the fees and expenses of counsel employed by the indemnified party for any period during which the indemnifying party has not assumed the defense thereof (other than during any period in which the indemnified party shall have failed to give notice of the Third-Party Claim as provided above). Whether or not the indemnifying party assumes the defense of a Third-Party Claim, the indemnified party shall not admit any liability with respect to, or settle, compromise or discharge, such Third-Party Claim without the indemnifying party’s prior written consent (which consent shall not be unreasonably withheld). If the indemnifying party assumes the defense of a Third-Party Claim, the indemnified party shall agree to any settlement, compromise or discharge of a Third-Party Claim that the indemnifying party may recommend and that by its terms obligates the indemnifying party to pay the full amount of the liability in connection with such Third-Party Claim and which releases the indemnified party completely in connection with such Third-Party Claim.

(c) Other Claims. In the event that any indemnified party has a claim against any indemnifying party under Section 10.02 or 10.03 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 10.01, the failure by any indemnified party to notify the indemnifying party shall not relieve the indemnifying party from any liability that it may have to such indemnified party under Section 10.02 or 10.03, except to the extent that the indemnifying party demonstrates that it has been prejudiced by such failure.

(d) Mitigation. Purchaser, OMG 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

- 51 -

indemnify the other party hereunder, including by making commercially reasonably efforts to mitigate or resolve any such claim or liability. In the event that Purchaser, OMG or the Sellers shall fail to make such commercially reasonable 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 that could reasonably be expected to have been avoided if Purchaser (on one hand) or OMG or the Sellers (on the other hand), as the case may be, had made such efforts.

SECTION 10.05. No Additional Representations. Purchaser acknowledges that, except as expressly set forth in this Agreement (as qualified by the Schedules):
