(d) Liabilities in respect of (i) Environmental Laws; (ii) Environmental Claims; (iii) Releases; and (iv) any and all other matters relating to the Environment arising out of or otherwise related to the U.S. Business, other than the Retained Environmental Liabilities, and subject to Seller’s obligations under Sections 12.03;

Section 2.04. Excluded Liabilities. Purchaser will not assume or be liable for any Excluded Liabilities, which shall remain the responsibility of Seller and the Selling Affiliate. “Excluded Liabilities” shall mean:

(a) From time to time following the Closing, Seller and Purchaser shall, and Seller shall cause the Selling Affiliate to, execute, acknowledge and deliver all such further conveyances, notices, assumptions, releases and acquittances and such other instruments, and shall take such further actions, as may be reasonably necessary or appropriate to assure fully to Purchaser and its successors or assigns, all of the rights, title and interests intended to be conveyed to Purchaser under this Agreement and the Transfer Documents and to assure fully to Seller and the Selling Affiliate and their successors and assigns the assumption of the liabilities and obligations intended to be assumed by Purchaser under this Agreement and the Transfer Documents, and to otherwise make effective the transactions contemplated hereby and thereby.

(b) Nothing in this Agreement nor the consummation of the transactions contemplated hereby shall be construed as an attempt or agreement to assign any Purchased Asset or Shares, including any Contract, Permit, certificate, approval, authorization or other right, which by its terms or by Law is not assignable without the consent of a third party or a Governmental Authority or is cancelable by a third party in the event of an assignment unless and until such consent shall have been obtained. Seller shall use its commercially reasonable efforts to cooperate with Purchaser at its request for up to 90 days following the Closing Date in endeavoring to obtain such consents promptly and shall cooperate with Purchaser and its Affiliates in any lawful, contractually permitted and economically feasible arrangement to provide that Purchaser and its Affiliates shall receive the interest of Seller and the Selling Affiliate in the benefits under any such Contract, Permit, certificate, approval, authorization or other right, including performance by Seller or the Selling Affiliate as agent; provided that

Purchaser shall, or shall cause its applicable Affiliate to, undertake to pay or satisfy the corresponding liabilities for the enjoyment of such benefit to the extent Purchaser, or its applicable Affiliate, would have been responsible therefor hereunder if such consent had been obtained. Any and all upfront amounts paid for administrative costs to obtain a consent, whether before or after the Closing Date, shall be borne equally by Purchaser and Seller. All costs associated with obtaining a consent other than those costs described in the foregoing sentence shall be borne by Purchaser.

Section 2.06. Bulk Sales Laws. Purchaser hereby waives compliance by Seller and the Selling Affiliate with the requirements and provisions of any “bulk-transfer” Laws of any jurisdiction that may otherwise be applicable with respect to the sale of any or all of the Purchased Assets to Purchaser.

Section 2.07. Purchase and Sale of the Shares of the Company. On the terms and subject to the conditions set forth in this Agreement, at the Closing Purchaser shall purchase, acquire and accept from the Selling Affiliate, and Seller shall cause the Selling Affiliate to sell, transfer, assign, convey and deliver to Purchaser, all of the Shares.

(a) Calculation and Payment of Purchase Price. In consideration for the transfer by Seller and the Selling Affiliate to Purchaser of the Purchased Assets and the Shares, Purchaser shall assume the Assumed Liabilities and pay to Seller and/or the Selling Affiliate (as directed by Seller):

(i) US$175,000,000 in cash at Closing (the “Closing Cash Consideration”, and, as adjusted pursuant to Sections 3.02, 7.03(c), 9.08 and 10.14, the “Adjusted Closing Cash Consideration”);

(ii) an aggregate of US$135,900,000 in principal and interest payments pursuant to the U.S. Promissory Notes;

(iii) an aggregate of US$90,600,000 in principal and interest payments pursuant to the Japan Promissory Notes; and

(iv) the amounts set forth in the Contingent Payment Agreement, upon the terms set forth therein.

The Adjusted Closing Cash Consideration shall be paid by wire transfer of immediately available funds to an account or accounts designated in writing by Seller to Purchaser at least three (3) Business Days prior to the Closing. The Initial Purchase Price shall be subject to adjustment as set out in the Final Closing Statement determined in accordance with Section 3.03 (as so adjusted, the “Final Purchase Price”).

(b) Purchase Price Allocation. Seller and Purchaser will allocate the Purchase Price among the Shares and the Purchased Assets in accordance with the principles set forth on Schedule 3.01(b) and a statement (the “Allocation Statement”) to be provided by Seller to Purchaser as soon as practicable after the Closing, which statement will be prepared in accordance with Section 1060 of the Code. If Purchaser disagrees with the Allocation Statement provided by Seller and the parties are unable to reach agreement, the matter will be resolved by an Independent Accounting Firm selected in the manner specified in Section 3.03(c). The decision of the Independent Accounting Firm as to the resolution of the dispute will be conclusive and binding on the parties. The fees and expenses of the Independent Accounting Firm will be divided equally between Seller and Purchaser. Seller and Purchaser will file all Tax Returns (including Form 8594) on a basis that is consistent with the Allocation Statement or the decision of the Independent Accounting Firm, as the case may be, and will take no position inconsistent therewith for Tax purposes unless required by an administrative or judicial determination.

(a) The Closing Cash Consideration may be increased or decreased by the Working Capital Adjustment, if any. The “Working Capital Adjustment” (which may be a positive or a negative number) shall be an amount equal to (x) the Transferred Working Capital (defined below) minus (y) the Target Working Capital (also defined below).

(i) “Transferred Working Capital” means an amount equal to the following items, in the aggregate:

(A) Prepayments. Any prepayment of Tax or other costs or obligations by Seller or the Selling Affiliate on or before the Closing Date with respect to periods after the Closing Date, shall be reflected as an asset on the Working Capital Estimate (defined below) and the Closing Statement (also defined below).

(B) Deferred Payments. All deferred or otherwise outstanding payment obligations associated with the Owned Properties or Real Property Leases which relate to liabilities that have been incurred on or prior to the Closing Date that have been assumed by Purchaser or for which Purchaser is otherwise responsible shall be reflected as a liability on the Working Capital Estimate and the Closing Statement.

(C) Other Prorations. All prepayments, rents, current property or ad valorem Taxes of the current year, salaries, assessments, utilities, maintenance charges and similar expenses associated with the Owned Properties or Real Property Leases shall be prorated between Seller and the Selling Affiliate (as applicable) on the one hand, and Purchaser on the other hand, as of the Closing Date. To the extent such proration has not been effected by other means and to the extent of information then available, such proration shall be reflected on the Working Capital Estimate and the Closing Statement.

(b) Working Capital Estimate. An estimate of the Working Capital Adjustment shall be calculated by Seller and set forth in an estimate (the “Working Capital Estimate”) delivered to Purchaser not later than five (5) Business Days prior to the scheduled date for Closing. The Working Capital Estimate shall contain information detailing the basis for Seller’s calculations, and Purchaser and its representatives shall have access to such records of Seller and the Selling Affiliate as may be reasonably requested for verifying and confirming such amounts and calculations. If the Working Capital Adjustment set forth on the Working Capital Estimate is a positive number, such amount shall be added to the Closing Cash Consideration and paid by Purchaser to Seller and/or the Selling Affiliate on the Closing Date. If the Working Capital Adjustment set forth on the Working Capital Estimate is a negative number, such amount shall be deducted from the Closing Cash Consideration.

(a) Closing Statement. Within one hundred and twenty (120) calendar days after the Closing, Purchaser shall deliver to Seller a written statement (the “Closing Statement”) setting forth Purchaser’s calculation of (i) the Working Capital Adjustment and (ii) the Net Accounts Receivables as of the point in time immediately prior to the Closing (the “Closing Net Accounts Receivable”). The Closing Statement shall contain information detailing the basis for Purchaser’s calculations, and Seller and its representatives shall have access to such records of Purchaser as may be reasonably requested for verifying and confirming such amounts and calculations. Purchaser and Seller agree to be reasonably available at each other’s request to meet and discuss the preparation of the Closing Statement. The “Final Closing Statement” shall be (i) the Closing Statement in the event that no Notice of Dispute with respect thereto is delivered to Purchaser in accordance with Section 3.03(c) below or (ii) the Closing Statement as adjusted by (A) the agreement of Seller and Purchaser and/or the Independent Accounting Firm (defined below). The “Final Working Capital Adjustment” shall be the Working Capital Adjustment set forth in the Final Closing Statement. The “Final Closing Net Accounts Receivable” shall be the Closing Net Accounts Receivable set forth on the Final Closing Statement.

(i) If the Working Capital Adjustment set forth on the Working Capital Estimate exceeds the Final Working Capital Adjustment by more than US$50,000, then Seller shall pay to Purchaser the total amount of such excess, with interest as provided in Section 3.03(e), as an adjustment to the Initial Purchase Price, exclusive of any Transfer Taxes and without reduction for any withholding Taxes. If the Final Working Capital Adjustment exceeds the Working Capital Adjustment set forth on the Working Capital Estimate by more than US$50,000, then Purchaser shall pay to Seller the total amount of such excess, with interest as provided in Section 3.03(e), as an adjustment to the Initial Purchase Price, exclusive of any Transfer Taxes and without reduction for any withholding Taxes.

(ii) If the Target Net Accounts Receivable exceeds the Final Closing Net Accounts Receivable by more than US$50,000, then Seller shall pay to Purchaser the total amount of such excess, with interest as provided in Section 3.03(e), as an adjustment

to the Initial Purchase Price, exclusive of any Transfer Taxes and without reduction for any withholding Taxes. If the Final Closing Net Accounts Receivable exceeds the Target Net Accounts Receivable by more than US$50,000, then Purchaser shall pay to Seller the total amount of such excess, with interest as provided in Section 3.03(e), as an adjustment to the Initial Purchase Price, exclusive of any Transfer Taxes and without reduction for any withholding Taxes.

(iii) Any payment required to be made pursuant to this Section 3.03(b) shall be made by wire transfer of immediately available funds to an account or accounts designated in writing by the receiving party for such purpose or by such other means as mutually agreed upon by the parties, in each case, not later than the fifth Business Day after the date of the final determination of the Final Closing Statement.

(c) Resolution of Objections. If Seller gives to Purchaser written notice of dispute (a “Notice of Dispute”) of any element of the Closing Statement within thirty (30) calendar days after receiving the Closing Statement, the disputed amount shall be negotiated between Seller (for itself and/or on behalf of the Selling Affiliate, as applicable) and Purchaser. After the delivery by Seller to Purchaser of any such Notice of Dispute, Purchaser and Seller shall use their reasonable best efforts to reconcile their differences with respect to any disputed amount, and any written resolution by them as to any disputed item set forth in the Notice of Dispute shall be final and binding on the parties hereto. If Purchaser and Seller are unable to reach a resolution on all disputed items within thirty (30) calendar days after the delivery of the Notice of Dispute, either Purchaser or Seller may, by written notice, submit the items remaining in dispute for resolution to an internationally recognized firm of independent public accountants reasonably acceptable to both Purchaser and Seller (the “Independent Accounting Firm”), whereupon each of Purchaser and Seller shall promptly furnish to the Independent Accounting Firm such party’s final offer for the settlement of all items remaining in dispute (each a “Final Offer”). If Purchaser and Seller are unable to agree upon the selection of the Independent Accounting Firm within thirty (30) calendar days after the delivery of the Notice of Dispute, then each party shall promptly thereafter designate one internationally recognized firm of independent public accountants. The parties shall cause such firms promptly thereafter jointly to select a third firm to serve as the Independent Accounting Firm (which shall be an internationally recognized firm of independent public accountants that does not have a material business relationship with either Seller or Purchaser or any of their respective Affiliates), and any such selection shall be binding on Purchaser and Seller with respect to resolving such disputed items. The Independent Accounting Firm shall resolve such disputed items in a manner which is consistent with this Agreement but which shall not exceed the Final Offer of either Seller or Purchaser. All dispute resolution proceedings in connection with the Closing Statement or amount payable hereunder shall take place at the offices of the Independent Accounting Firm in New York, New York or at such other location as Purchaser and Seller may otherwise mutually agree in writing.

(d) Independent Accounting Firm. Each of the parties shall furnish, at its own expense, the Independent Accounting Firm and the other parties hereto with such documents and other written information as the Independent Accounting Firm may request in connection with resolving the disputed items. Each party may also furnish to the Independent Accounting Firm such other written information and documents as such party deems relevant; provided, that copies of all such documents and materials shall be concurrently delivered to the other parties to

the proceedings in the same form and manner as such materials are delivered to the Independent Accounting Firm. The Independent Accounting Firm may, at their discretion, conduct one or more conferences with respect to the dispute between Purchaser and Seller, at which conference each party shall have the right to present such additional documents, materials and other information and to be accompanied or represented by such advisors, counsel and accountants as each party shall choose in its sole discretion. Purchaser and Seller shall instruct the Independent Accounting Firm to render their written decision with respect to all matters submitted to them by Purchaser and Seller as promptly as practicable. The Independent Accounting Firm shall determine the proportion of their fees and expenses to be paid by Purchaser and Seller, respectively, in accordance with the relative merits of the parties’ positions. Purchaser and Seller shall promptly pay their respective shares of the fees and expenses of the Independent Accounting Firm. The determination of the Independent Accounting Firm as to all disputed items shall be final and binding upon Purchaser and Seller, except in the case of manifest error or actual fraud. The disputed amount shall be payable by the party owing such amount within five (5) Business Days following resolution or determination of the dispute. The failure of Seller to provide a Notice of Dispute within the thirty (30) calendar day time period referred to in Section 3.02(c) shall be deemed an acceptance by Seller of the Settlement Statement.

(e) Interest. Any amount owing hereunder with respect to the Final Closing Statement that is not paid within the applicable time period set forth above shall bear interest on the amount due from the Closing Date to and including the date paid in full at an annual interest rate equal to the ninety (90)-day U.S. Treasury Bill rate in effect as of the Closing Date (as reported in The Wall Street Journal). All such computations of interest shall be made by the party entitled to receive payment on the basis of a year of 360 days, in each case for the actual number of days occurring in the period for which such interest is payable.

Section 4.01. Closing. The closing of the transactions contemplated hereunder (the “Closing”) shall take place at the offices of Jones Day, 222 East 41^st Street, New York, New York, 10017 at 10:00 a.m. (local time in New York, New York) on the fifth Business Day after the satisfaction or waiver of the conditions set forth in Article XI occurs (other than those conditions that by their terms are to be satisfied at the Closing, but subject to the satisfaction or waiver of such conditions), or at such other date or place as Purchaser and Seller may agree, it being understood that, if required by applicable Law, Seller may request that the Closing be comprised of separate “closings” in one or more local jurisdiction(s) where the Shares, any Purchased Assets or Assumed Liabilities are being transferred and may request that Purchaser pay or cause to be paid portions of the Initial Purchase Price and the Final Purchase Price payable in accordance with Section 3.01(a) directly or indirectly to the Selling Affiliate in the local currency of any such jurisdiction.

For a period of three (3) years from the Closing Date, Seller shall not, and Seller shall cause Seller’s controlled Affiliates not to, directly or indirectly, without the prior written consent of Purchaser (i) produce, market, sell, lease or develop anywhere in the world any tantalum or niobium powder or fabricated products or alloys having a principal component consisting of tantalum or niobium metal or any other metal powders suitable for use in capacitor anodes and sputtering targets, (ii) induce or attempt to induce any person, who is at Closing or has been at any time within the twelve (12) months prior to Closing a supplier of goods or services to the Business, to cease to supply, or to restrict or vary the terms of supply, to the Business or (iii) do or say anything that is harmful to the reputation of the Business or that could lead a Person to cease to deal with the Business on substantially equivalent terms to those previously offered or at all (the “Competitive Activities”).

(b) Exceptions. Notwithstanding the foregoing, this Section 7.04 shall not be deemed breached as a result of the ownership by Seller or any of its controlled Affiliates of: (i) less than ten percent (10%) of any class of stock of a Person engaged, directly or indirectly, in Competitive Activities; (ii) less than ten percent (10%) of the aggregate value of all Indebtedness of a Person engaged, directly or indirectly, in Competitive Activities; or (iii) all or a portion of a Person that engages, directly or indirectly, in Competitive Activities if such Competitive Activities account for less than ten percent (10%) of such Person’s consolidated annual revenues, provided that if, at the time of Seller’s or its controlled Affiliate’s acquisition of ownership of all or a portion of such a Person, such Person derives ten percent (10%) or more of its consolidated annual revenues from Competitive Activities, then Seller or such Affiliate, as applicable, shall have twelve (12) months following such acquisition to cause to be divested a portion of such Person’s business such that, immediately following such divestiture, Competitive Activities account for less than ten percent (10%) of such Person’s consolidated annual revenues, in which case this Section 7.04 shall not be deemed breached by such ownership.

(b) In the event any Purchased Asset that is a tangible asset is destroyed or damaged, in whole or in part, by fire or other casualty prior to the Closing, then in lieu of making a claim in accordance with Section 7.05(a), Seller may repair or replace (with similar grade and quality) such damaged asset before the Closing Date and such repaired or replaced asset shall constitute a Purchased Asset, in which case Purchaser shall not have any right, claim or title to any insurance proceeds relating to such asset.

(c) a written consent (in form and substance reasonably satisfactory to Purchaser) for the transfer of each Real Property Lease from the landlord or other party whose consent thereto is required under such Real Property Lease (the “Lease Consents”).

Section 7.08. Confidentiality. From and after the Closing Date, for a period of three (3) years after the Closing Date, Seller agrees and agrees to cause the Selling Affiliate, to treat all confidential data, reports, records, processes, know-how and other information it has developed or has in its control or possession relating to the Business, whether or not marked as confidential or proprietary (the “Information”), as confidential and to not disclose, discuss or reveal such Information to a third party without the prior written consent of Purchaser, unless Seller or the Selling Affiliate are required by applicable Law or order of a Government Authority to disclose any such Information and Seller or Selling Affiliate have informed Purchaser of such requirement and given Purchaser a reasonable opportunity to contest such requirement or to seek a protective order or a stay of such disclosure order. Seller agrees to exercise all reasonable efforts to avoid the disclosure of such Information to any third party. The obligations in this Section 7.08 shall not apply to any portion of the Information:

(a) which is or becomes, through no act or failure on Seller’s or the Selling Affiliate’s part, published information known on a non-confidential basis; or

(b) which corresponds in substance to information hereafter furnished to Seller or the Selling Affiliate by others as a matter of right without restriction on disclosure; or

related information, documentation and correspondence, and (iii) exercise reasonable best efforts to consult with Purchaser prior to exchanges of material information or material negotiations with any Person (Purchaser to make itself reasonably available and without unreasonable delay as to same). Such remedial actions and negotiations shall be performed in a commercially reasonable manner, including, to the extent allowed or authorized by applicable Environmental Law or the Governmental Authority having jurisdiction over a remedial action, the use of applicable commercial and/or industrial remediation standards and institutional controls. Seller agrees that, in conducting any remedial action or seeking a particular remedy or agreed remediation standard, it shall not unreasonably interfere with Purchaser’s business operations. Notwithstanding anything to the contrary contained herein, Seller shall not enter into any settlement or judgment, without Purchaser’s prior written consent, such consent not to be unreasonably withheld, that would encumber or impose on the Business or the Purchased Assets any restriction or condition that would materially and adversely affect the Purchaser or the Business. Purchaser may comment on Seller’s proposed remedial actions and may participate at its expense in any meetings or discussions with relevant Governmental Authorities, but Purchaser shall have no right to perform or participate in any aspect of any remedial actions performed or directed by Seller; provided, however, that Purchaser shall provide reasonable access to Seller and its environmental consultants to any property within the control of Purchaser that is subject to any remedial action obligation of Seller under this Agreement.

(b) Notwithstanding anything in Section 7.09(a), from and after the Closing, Purchaser shall control all remediation actions and all negotiations with any Governmental Authority or any other Person in respect to those Special Environmental Liabilities set forth on Schedule 7.09(b). For so long as Seller is required to indemnify Purchaser and the Purchaser Indemnified Parties for such Liabilities, Seller shall reimburse Purchaser for the reasonable costs associated with continued implementation of such remedial program within 60 days of receipt of invoices for any remedial work relating thereto. Any material changes to the existing remedial program relating to such Liabilities must be approved in writing by Seller, which approval may not be unreasonably withheld, conditioned or delayed. Purchaser shall provide copies of relevant non-privileged reports and submissions to Seller regarding such remediation activities.

In any event, Seller’s remediation obligations with respect to the Special Environmental Liabilities shall cease at the termination of the indemnity period set forth in Section 12.06(g).

(a) Confidential Information Regarding the Business. Prior to the Closing Date and, if this Agreement is terminated without the Closing having occurred, after such termination, Purchaser will, and will cause its Affiliates and Purchaser’s Representatives to, comply with the terms of the Confidentiality Agreement, dated January 20, 2011, by and between Purchaser and Seller (the “Confidentiality Agreement”).

Purchaser acknowledges that Seller and its Affiliates could be irreparably damaged if any trade secrets or other information that is confidential, non-public or proprietary to Seller or any of its Affiliates that does not relate to the Business (the “Seller Information”) was disclosed by Purchaser, its Affiliates or any Purchaser Representative to any Person and, from and after the Closing Date, for a period of three (3) years after the Closing Date, Purchaser will not, and will cause its Affiliates and each Purchaser Representative not to, at any time, without the prior written consent of Seller, disclose or use (or permit to be disclosed or used) in any way any such Seller Information (regardless of whether such Seller Information was obtained during the course of pursuing the transactions contemplated by this Agreement or following the Closing from a Transferred Employee), unless such Seller Information (i) was already in Purchaser’s possession prior to Purchaser’s entry into the Confidentiality Agreement; provided that such Seller Information is not known by Purchaser to be subject to another confidentiality agreement with or other obligation of secrecy to Seller or another party, (ii) becomes generally available to the public other than as a result of a disclosure by Purchaser, its Affiliates or any Purchaser Representative, or (iii) becomes available to Purchaser on a non-confidential basis from a source other than Seller, its Affiliates or any of their respective representatives; provided that such source is not known by Purchaser to be bound by a confidentiality agreement with or other obligation of secrecy to Seller or another party.

The party that is legally required to pay any transfer, documentary, sales, use, registration and other such Taxes (including all applicable real estate transfer Taxes) and related fees (including any penalties, interest and additions to Tax) arising out of or incurred in connection with this Agreement (“Transfer Taxes”) shall pay such Taxes. The party that is legally required to file a Tax Return relating to Transfer Taxes shall be responsible for preparing and timely filing such Tax Return.

Section 8.05. Change of Directors. Purchaser shall, at the Closing or as soon as practicable after the Closing, (i) appoint its nominated directors of the Company and (ii) register the resignation of the directors of the Company nominated by Seller and the appointment of the new directors of the Company.

For the avoidance of doubt, Purchaser shall be responsible for payment of the filing fee, but each of Purchaser and Seller shall be responsible

for any associated costs, including legal costs, relating to filing and obtaining consent, approval or waiver under the HSR Act.

(a) General. Seller and Purchaser shall cooperate with one another in (i) determining whether any action in respect of (including any filing with), or consent, approval or waiver by, any Governmental Authority is required in connection with the consummation of the transactions contemplated by this Agreement (including in relation to the transfer, modification or reissuance of any Permit), (ii) taking any such actions (including making any filing or furnishing any information required in connection therewith) in order to obtain any such consent, approval or waiver on a timely basis and (iii) keeping the other party promptly informed in all material respects with respect to any communication given or received in connection with any such action, consent, approval or waiver, including providing to each other in advance any analyses, appearances, presentations, memoranda, briefs, arguments, opinions and proposals made or submitted to a Governmental Authority by or on behalf of any party.

No party hereto shall participate in any meeting with any Governmental Authority with respect to the HSR Act or any Competition Law as they relate to the transactions contemplated hereby (except in the case of Purchaser for any meetings between Purchaser and any Governmental Authority to discuss possible remedies), unless it consults with the other parties hereto in advance and, to the extent permitted by such Governmental Authority, gives such other parties the opportunity to attend and participate thereat.

Without limiting the provisions set forth in paragraphs (a) and (b) above, Purchaser shall use commercially reasonable efforts to obtain any consent, approval or waiver relating to the HSR Act or any Competition Law that is required for the consummation of the transactions contemplated by this Agreement. For the avoidance of doubt, if any administrative or judicial action or proceeding is instituted (or threatened to be instituted) challenging the transactions contemplated by this Agreement as violative of any Competition Law, or if any judgment or Law is enacted, entered, promulgated or enforced by a Governmental Authority that would make such transactions illegal or would otherwise prohibit or materially impair or delay the consummation of such transactions, Purchaser shall use commercially reasonable efforts to contest and resist in good faith any such action or proceeding and shall use commercially reasonable efforts to have vacated, lifted, reversed or overturned any judgment, whether temporary, preliminary or permanent, that is in effect and that prohibits, prevents or restricts consummation of the transactions contemplated by this Agreement.

Section 10.13. Employee Communications. Seller and Purchaser shall cooperate in communications with U.S. Transferred Employees with respect to employee benefit plans maintained by Seller or Purchaser and with respect to other matters arising in connection with the transactions contemplated by this Agreement; provided, however, that from and after the Closing, nothing herein will restrict in any manner Purchaser’s communications with any U.S. Transferred Employees.

(a) As soon as practicable after the Closing but no later than twelve (12) months from the Closing, Purchaser shall cause the Company to establish a defined benefit plan (the “Company Benefit Plan”) for the benefit of the Company’s employees transferred from the Selling Affiliate to the Company pursuant to the Corporate Split Agreement (“Japanese Transferred Employees”). The terms and conditions of the Company Benefit Plan shall be consistent with the terms and conditions of the defined benefit plan that is presently sponsored by the Selling Affiliate and other Seller Affiliates in Japan (the “Japanese Benefit Plan”) as of the Closing. For avoidance of doubt, the Japanese Benefit Plan consists of the Employees’ Retirement Plan for Cabot Group.

(b) Purchaser shall cause the Company to become a co-sponsor in the Japanese Benefit Plan as of the Closing and remain such co-sponsor until the date the Company Benefit Plan is established (the “DB Transfer Date”) in order that the Japanese Transferred Employees may remain participants under the Japanese Benefit Plan until the DB Transfer Date. The sole financial obligation of the Company during its period of co-sponsorship shall be to pay for the required employer contributions to the fund for benefits earned during the period beginning on the Closing Date and ending on the DB Transfer Date in relation to the Japanese Transferred Employees. The accrued liability in the Japanese Benefit Plan for the Japanese Transferred Employees as of the DB Transfer Date shall be assumed in the Company Benefit Plan from and after the DB Transfer Date. Seller and Purchaser shall direct Mizuho Trust Bank, as operating agent, to determine the ratio of actuarial obligations (Suri-Saimu) for the Japanese Transferred Employees to other subject employees in the Japanese Benefit Plan as of the Closing (the “Ratio”). Purchaser shall have the Company, and Seller shall have the Selling Affiliate and its other Affiliates in Japan, split funded assets in the Japanese Benefit Plan into the Company Benefit Plan and the Japanese Benefit Plan as of the DB Transfer Date based on the Ratio.

(c) Seller shall instruct Towers Watson (the “Seller Actuary”) to determine the Underfunded Pension Amount as of the DB Transfer Date. The “Underfunded Pension Amount” shall be the projected benefit obligation for the Japanese Transferred Employees as of the DB Transfer Date minus the fair value of the funded assets of the Japanese Benefit Plan as valued by the administrator of such plans as at the date of this Agreement (being Mizuho Trust Bank) for the Japanese Transferred Employees at the DB Transfer Date. With the exception of the discount rate, all actuarial valuation assumptions shall be the same as were used in the most recently completed actuarial valuation for year-end disclosure purposes under GAAP. The discount rate used in the most recently completed actuarial valuation for year-end disclosure purposes under GAAP shall be adjusted with any movement in the yield on Japanese government 10-year bonds between the valuation date and the month end preceding the DB Transfer Date. Each of the parties shall furnish, at its own expense, the Seller Actuary with such documents and other written information as the Seller Actuary may request in connection with determining the Underfunded Pension Amount (including without limitation the funded status of plans, cash flow, plan asset information, amortization amounts during the relevant period on which the valuation is based, plan provisions, membership data and asset information) and the chief financial officer of the party furnishing such information shall certify that such information is accurate and complete in all material respects as at the date of furnishing such information or the date otherwise expressly certified therein. The fees and expenses of the Seller Actuary will be borne by Seller.

(d) Seller shall instruct the Seller Actuary to deliver a certificate (the “Actuary Certificate”) to Seller and Purchaser setting forth its determination of the Underfunded Pension Amount, together with the actuarial valuation report, actuarial assumptions and methods and supporting documentation, as promptly as practicable after the DB Transfer Date. Purchaser may appoint its own actuary (the “Purchaser Actuary”) to review the Seller Actuary’s calculations. Purchaser shall have ten (10) Business Days to review the Seller Actuary’s calculations and respond in writing with any questions regarding the calculations. To the extent the Seller Actuary and the Purchaser Actuary cannot agree on a final Underfunded Pension Amount, a third party independent actuary (the “Third Party Actuary”) shall be jointly appointed by Purchaser and Seller, the findings of whom shall be binding on both parties and the cost of whom shall be borne equally by Purchaser and Seller. Within ten (10) days after finalization of the Underfunded Pension Amount, Seller shall pay to Purchaser such Underfunded Pension Amount.

(e) At Closing, Seller will pay all obligations under the Cabot Supermetals Directors’ Retirement Plan and any other retirement plan relating to the Japanese Transferred Employees other than the Employees’ Retirement Plan for Cabot Group.

(a) Each of Purchaser and Seller recognize it to be in the best interests of the parties hereto and their respective employees that the transactions in this Article X be effected in an orderly manner and agree to devote their respective reasonable best efforts and to cooperate fully in complying with the provisions of this Article X. Without limiting the generality of the foregoing, each of the parties agree to execute, deliver and file all documents and to take all such

actions as are reasonably necessary or desirable in order to carry out and perform the purposes of this Article X and to facilitate the transactions referred to in this Article X.

(b) Without limiting the generality of Section 10.14(a), Seller shall use its commercially reasonable efforts to cooperate with Purchaser promptly at its request for up to 90 days following the Closing Date in endeavoring to obtain the consent of any significant contractors of the Business immediately prior to Closing to have the Purchaser (or its Affiliates) engage such contractors in the Business from and after Closing.

Section 10.16. No Third Party Beneficiary or Employee Rights. Nothing in this Article X expressed or implied shall (a) create any third-party beneficiary or other rights in any employee or former employee (including any beneficiary or dependent thereof) of Seller, the Company or the Selling Affiliate or any other Person other than the parties hereto and their respective successors and permitted assigns, (b) constitute or create an employment agreement or (c) constitute or be deemed to constitute an amendment to any employee benefit plan sponsored or maintained by Seller, the Selling Affiliate, the Company, Purchaser or any of Purchaser’s Affiliates.

Section 11.02. Conditions to Obligation of Purchaser. The obligation of Purchaser to consummate the Closing is subject to the satisfaction (or waiver to the extent permitted by applicable Law) of the following further conditions:

(a) Representations and Warranties. The representations and warranties of Seller contained in this Agreement (i) shall have been true and correct when made and (ii) shall be true and correct as of the Closing Date, with the same force and effect as if made as of the Closing Date (in each case of clauses (i) and (ii) other than such representations and warranties as are made as of another date, which shall be true and correct only as of such date), and in each case of clauses (i) and (ii) except where the failure of such representations and warranties, in the aggregate, to be so true and correct (without giving effect to any limitations or qualifications as to “materiality” (including the word “material”) or “Material Adverse Effect” set forth therein) would not have a Material Adverse Effect.

(b) Agreements and Covenants. Seller shall have performed or complied in all material respects with all agreements and covenants required by this Agreement to be performed or complied with by it on or prior to the Closing Date.

Neither Purchaser nor Seller may rely on the failure of any condition set forth in Section 11.01, Section 11.02 or Section 11.03, as the case may be, to be satisfied if such failure was caused by such party’s failure to comply with its obligations to consummate the transactions contemplated by this Agreement as required by the provisions of this Agreement, including Section 9.01.

(a) The representations and warranties of Seller and Purchaser contained in this Agreement shall survive the Closing for the applicable time period set forth in this Section 12.01, which time period shall serve as a contractual statute of limitations for indemnification claims. All of the representations and warranties of Seller and Purchaser contained in this Agreement and all claims and causes of action for the breach thereof shall terminate on the date that is eighteen (18) months after the Closing Date, except that (i) the representations and warranties contained in Sections 5.08(b) (Compliance with Law) and 5.17 (Tax Matters) shall terminate on the date that is ninety (90) days after the expiration of the applicable statute of limitations; (ii) the representations and warranties contained in Section 5.13 (Environmental Matters) shall terminate on the date that is four (4) years after the Closing Date; and (iii) the representations and warranties contained in Sections 5.01 (Organization, Power and Authorization; Binding Effect), 5.05 (Title to Purchased Assets; Sufficiency) and 6.01 (Organization, Power and Authorization; Binding Effect) shall survive indefinitely. In the event notice of any claim for indemnification under Section 12.02(a) or Section 12.03(a) shall have been given pursuant to Section 14.01 within the applicable survival period, the representations and warranties that are the subject of such indemnification claim shall survive until such time as such claim is finally resolved.

(b) The covenants and agreements of the parties hereto contained in this Agreement shall survive in accordance with their respective terms.

Section 12.02. Indemnification by Purchaser. From and after the Closing, Purchaser hereby agrees to indemnify, defend and hold harmless Seller, the Selling Affiliate, their respective Affiliates and, if applicable, their respective directors, officers, stockholders, partners, attorneys, accountants, agents, employees, heirs, successors and assigns (the “Seller Indemnified Parties”) from, against and in respect of any Losses actually incurred by any of the Seller Indemnified Parties resulting from or arising out of (a) any breach of any representation or warranty made by Purchaser contained in this Agreement, (b) the breach of any covenant or agreement of Purchaser contained in this Agreement, (c) any Assumed Liability or (d) the conduct of the Business or the ownership or use of the Purchased Assets after the Closing Date. The Seller Indemnified Parties shall not be entitled to assert any indemnification claim pursuant to clause (a) of this Section 12.02 (i.e., with respect to any breach of any representation or warranty made by Purchaser contained in this Agreement) after the expiration of the applicable survival period set forth in Section 12.01(a) (except to the extent provided therein) and, in each such case, any such claim shall be irrevocably and unconditionally released and waived by the

Seller Indemnified Parties upon such expiration, whether or not a longer period would be permitted by applicable Law.

Section 12.03. Indemnification by Seller. From and after the Closing, Seller hereby agrees to indemnify, defend and hold harmless Purchaser, its Affiliates and, if applicable, their respective directors, officers, stockholders, partners, attorneys, accountants, agents, employees, heirs, successors and assigns (the “Purchaser Indemnified Parties” and, collectively with the Seller Indemnified Parties, the “Indemnified Parties”) from, against and in respect of any Losses actually incurred by any of the Purchaser Indemnified Parties resulting from or arising out of (a) any breach of any representation or warranty made by Seller contained in this Agreement, (b) the breach of any covenant or agreement of Seller contained in this Agreement, (c) any Excluded Liability or Excluded Asset, or (d) any Special Environmental Liability. For purposes of clause (a) of the immediately preceding sentence, all “materiality,” “Material Adverse Effect” and similar materiality qualifiers contained in such representations and warranties shall be disregarded (other than those set forth in Sections 5.06 (Financial Statements), 5.09(a) (Contracts) and 5.11(a) (Intellectual Property)). The Purchaser Indemnified Parties shall not be entitled to assert any indemnification claim pursuant to clause (a) of this Section 12.03 (i.e., for breach of any representation or warranty made by Seller contained in this Agreement) after the expiration of the applicable survival period set forth in Section 12.01(a) (except to the extent provided therein) and, in each such case, any such claim shall be irrevocably and unconditionally released and waived by the Purchaser Indemnified Parties upon such expiration, whether or not a longer period would be permitted by applicable Law.

(a) With respect to third party claims, all claims for indemnification by any Indemnified Party hereunder shall be asserted and resolved as set forth in this Section 12.04.

(b) In the event that any written claim or demand for which Seller or Purchaser, as the case may be (an “Indemnifying Party”), may be liable to any Indemnified Party hereunder (after giving effect to the limitations set forth in this Article XII) is asserted against or sought to be collected from any Indemnified Party by a third party, such Indemnified Party shall promptly, but in no event more than thirty (30) days following such Indemnified Party’s receipt of such claim or demand, notify the Indemnifying Party of such claim or demand in reasonable detail (taking into account the information then available to the Indemnified Party) and the amount or the estimated amount thereof to the extent then feasible (the “Claim Notice”). The Indemnifying Party shall have thirty (30) days from receipt of the Claim Notice (the “Notice Period”) to notify the Indemnified Party (i) whether or not the Indemnifying Party disputes the liability of the Indemnifying Party to the Indemnified Party hereunder with respect to such claim or demand and (ii) whether or not the Indemnifying Party elects to defend the Indemnified Party against such claim or demand. All costs and expenses incurred by the Indemnifying Party in defending such claim or demand shall be a liability of, and shall be paid by, the Indemnifying Party; provided, however, that the amount of such costs and expenses that shall be a liability of the Indemnifying Party hereunder shall be subject to the limitations set forth in Section 12.06 and shall otherwise constitute Losses hereunder.

(c) Except as hereinafter provided, in the event that the Indemnifying Party notifies the Indemnified Party of its election to defend against such claim or demand, the Indemnifying Party shall have the right to defend the Indemnified Party by appropriate proceedings and shall have the sole power to direct and control such defense. The Indemnifying Party shall promptly inform the Indemnified Party upon request of the status of any claim. If any Indemnified Party desires to participate in any such defense, it may do so at its sole cost and expense, and the Indemnifying Party will not be liable to the Indemnified Party for legal expenses incurred by the Indemnified Party in connection with the defense thereof.

(d) The Indemnified Party shall not settle a claim or demand for which it is indemnified by the Indemnifying Party without the written consent of the Indemnifying Party. The Indemnifying Party shall not, without the prior written consent of the Indemnified Party, settle, compromise or offer to settle or compromise any such claim or demand on a basis that would have a continuing effect in any material respect on the Indemnified Party or any Affiliate thereof or any of their respective businesses, assets or operations.

(e) If the Indemnifying Party elects not to defend the Indemnified Party against such claim or demand, whether by failing to give the Indemnified Party timely notice as provided above or otherwise, then the amount of any such claim or demand, or, if the same be contested by the Indemnified Party, then that portion thereof as to which such defense is unsuccessful (including the reasonable costs and expenses pertaining to such defense) shall be the liability of the Indemnifying Party and shall constitute Losses hereunder, subject to the limitations set forth in Section 12.06.

(f) To the extent the Indemnifying Party shall direct, control or participate in the defense or settlement of any third party claim or demand, the Indemnified Party will provide the Indemnifying Party and its counsel access to, during normal business hours, relevant business records and other documents, and shall permit them to consult with the employees of and counsel to the Indemnified Party. The Indemnified Party shall use its reasonable best efforts to defend all such claims that the Indemnifying Party does not elect to defend. The failure of the Indemnified Party to give timely notice of a claim shall not relieve the Indemnifying Party of its indemnification obligations hereunder except to the extent such failure has actually prejudiced the Indemnifying Party.

(g) If an Indemnified Party desires to assert any claim for indemnification provided for under this Article XII other than a claim in respect of, arising out of or involving a third-party claim, such Indemnified Party shall notify the Indemnifying Party in writing, and in reasonable detail (taking into account the information then available to such Indemnified Party), of such claim promptly after becoming aware of the existence of such claim; provided, however, that the failure of the Indemnified Party to give timely notice of a claim shall not relieve the Indemnifying Party of its indemnification obligations hereunder unless such failure has actually prejudiced the Indemnifying Party.

Section 12.05. Characterization of Indemnification Payments. All amounts paid by Seller or Purchaser in respect of indemnification under this Article XII shall, to the extent permitted by Law, be treated for all purposes as adjustments to the Initial Purchase Price.

(a) Subject to Section 12.09 and except as otherwise provided herein, Seller shall have no Liability to the Purchaser Indemnified Parties for any Losses pursuant to this Agreement until the Losses actually incurred by the Purchaser Indemnified Parties exceed an aggregate amount equal to one percent (1%) of the Final Purchase Price (the “Threshold Amount”) and then only for Losses up to an aggregate amount equal to seventeen and one-half percent (17.5%) of the Final Purchase Price; provided, however, that no indemnity shall be recoverable by any the Purchaser Indemnified Party for any Losses actually incurred with respect to any individual item or matter unless the amount thereof exceeds US$100,000, and if such amount is not exceeded, then none of the Losses with respect to such item or matter will count toward satisfying the Threshold Amount. Notwithstanding the foregoing or anything to the contrary contained herein, the limitations on indemnification set forth in this Section 12.06(a) shall not apply to any Losses attributable to the Excluded Liabilities or the Special Environmental Liabilities or relating to or arising from any breach of the representations and warranties contained in Sections 5.01 (Organization, Power and Authorization; Binding Effect), 5.05 (Title to Purchased Assets; Sufficiency), 5.08(b) (Compliance with Law), 5.13 (Environmental Matters) or 5.17 (Tax Matters).

(b) An Indemnified Party’s right to indemnification pursuant to this Article XII on account of any Losses will be reduced by all insurance or other third party indemnification proceeds actually received by such Indemnified Party, and any such proceeds shall be taken into account for all purposes hereunder when calculating the Losses actually incurred by such Indemnified Party. The Indemnified Party shall use commercially reasonable efforts to claim and recover any Losses suffered by such Indemnified Party under any such insurance policies or other third party indemnities. The Indemnified Party shall remit to the Indemnifying Party any such insurance or other third party proceeds that are paid to the Indemnified Party with respect to Losses for which the Indemnified Party has been previously compensated pursuant to this Article XII.

(c) An Indemnified Party’s right to indemnification pursuant to this Article XII on account of any Losses will be reduced by the net amount of the Tax benefits actually realized by such Indemnified Party by reason of such Loss, and the net amount of any such Tax benefits shall be taken into account for all purposes hereunder when calculating the Losses actually incurred by such Indemnified Party. The Indemnified Party shall use commercially reasonable efforts to claim and realize all such Tax benefits.

(d) No Indemnified Party will be entitled to indemnification pursuant to this Article XII for Losses to the extent that such Indemnified Party has been compensated therefor pursuant to Section 3.02.

(e) The Purchaser Indemnified Parties’ right to indemnification pursuant to Section 12.03 on account of any Losses will be reduced by the amount of any reserve reflected on the Financial Statements established for the specific items or matters giving rise to such Loss.

(f) No Indemnified Party shall be entitled to recover from an Indemnifying Party more than once in respect of the same Losses.

(g) Notwithstanding any other provision of this Agreement, including without limitation this Section 12.06, Seller shall have no obligation to indemnify any Purchaser Indemnified Party (i) for claims arising after the fourth anniversary of the Closing Date for any breach of any of the representations or warranties contained in Section 5.13 (Environmental Matters), (ii) in respect of the Special Environmental Liabilities following the fourth anniversary of the Closing Date, or (iii) in excess of $20,000,000 in the aggregate for any breach of any of the representations or warranties contained in Section 5.13 (Environmental Matters) or in respect of the Special Environmental Liabilities.

(h) Notwithstanding any other provision of this Agreement, Seller’s obligation to indemnify the Purchaser Indemnified Parties for any breach of any of the representations contained in Section 5.13 (Environmental Matters) or in respect of the Special Environmental Liabilities shall be subject to the following limitations: (i) Seller shall not be responsible for any increase in the cost of cleanup of any Release of Hazardous Materials or correcting a non-compliance with Environmental Law to the extent that such increase resulted from any voluntary intrusive soil or groundwater sampling conducted in, on, at or under the Purchased Assets after the Closing Date by or on behalf of Purchaser, the Company or any of their respective employees or representatives which was not conducted in order to assess or otherwise respond to a claim or potential claim raised by a third party or to assess or prevent what Purchaser reasonably believes to be a material imminent threat to human health or the Environment; and (ii) Seller shall not be responsible for any costs to the extent such costs are incurred due to any material change in the use of any Seller Property after the Closing Date.

Section 12.07. Assignment of Claims. If the Indemnified Party receives any payment from an Indemnifying Party in respect of any Losses indemnified pursuant to Section 12.02 or Section 12.03 and the Indemnified Party could have recovered all or a part of such Losses from a third party (a “Potential Contributor”) based on the underlying Claim asserted against the Indemnifying Party, the Indemnified Party, at the request of the Indemnifying Party, shall assign such of its rights to proceed against the Potential Contributor as are necessary to permit the Indemnifying Party to recover from the Potential Contributor the amount of such payment.

Section 12.08. Mitigation. Any Indemnified Party shall take all reasonable steps to mitigate its Losses upon and after becoming aware of any event or condition that could reasonably be expected to give rise to any Losses that may be indemnifiable hereunder.

Section 12.09. Indemnification as Sole Remedy. From and after the Closing, except to the extent permitted under Section 14.04, the indemnity provided herein as it relates to this Agreement, the transactions contemplated by this Agreement and the Business shall be the sole and exclusive remedy of the Seller Indemnified Parties and the Purchaser Indemnified Parties with respect to any and all claims for Losses relating to or arising out of this Agreement or the transactions contemplated by this Agreement, whether based on contract, tort, statute, regulation or other Law, to the exclusion of all remedies provided by any Law in any jurisdiction, and Seller on behalf of the Seller Indemnified Parties and Purchaser on behalf of the Purchaser Indemnified Parties hereby waive any and all rights, both legal or equitable, to pursue any other remedies in respect of such claims.

Section 13.01. Termination. This Agreement may be terminated at any time prior to the Closing:

(b) by either Purchaser or Seller, by giving written notice of such termination to the other party, if any condition to such party’s obligations hereunder has not been satisfied or waived and the Closing shall not have occurred on or prior to December 31, 2011 (the “Termination Date”); provided that the Termination Date shall be automatically extended until March 31, 2012 if the conditions set forth in Section 11.01(a) have not been satisfied or waived by the parties and, as of such date, all other conditions to Closing have been or are capable of being timely satisfied; provided, further, that this Agreement may not be terminated pursuant to this Section 13.01(b) by a party that is in material breach of its obligations hereunder;

(c) by Purchaser by giving written notice to Seller if there has been a breach of any representation, warranty, covenant or agreement on the part of Seller contained in this Agreement such that the condition set forth in Section 11.02(a) or the condition set forth in Section 11.02(b) would not be satisfied, and which is either not capable of being cured prior to the Closing or, if such breach is capable of being cured, is not so cured within a reasonable amount of time (and in any event prior to the Termination Date).

(d) by Seller by giving written notice to Purchaser if there has been a breach of any representation, warranty, covenant or agreement on the part of Purchaser contained in this Agreement such that the condition set forth in Section 11.03(a) or the condition set forth in Section 11.03(b) would not be satisfied, and which is either not capable of being cured prior to the Closing or, if such breach is capable of being cured, is not so cured within a reasonable amount of time (and in any event prior to the Termination Date).

Section 13.02. Effect of Termination. In the event of the termination of this Agreement in accordance with Section 13.01, this Agreement shall thereafter become void and have no effect and neither party hereto (nor any equity holder, director, officer, employee, agent, consultant or representative of any such party) shall have any Liability to the other party hereto, except in each case for the obligations of the parties hereto contained in Section 7.07 (Seller Confidentiality), Section 8.01 (Confidentiality), Section 9.03 (Public Announcements), this Section 13.02 and, as applicable, Article XIV (Miscellaneous), each of which shall survive any termination of this Agreement pursuant to Section 13.01, and except that nothing herein will relieve any party from Liability for any breach of its covenants or agreements contained in this Agreement occurring prior to such termination.

Section 14.01. Notices. All notices or other communications hereunder shall be deemed to have been duly given and made if in writing and if delivered by personal delivery upon the party for whom it is intended, if delivered by registered or certified mail, return receipt

requested, or by a national overnight or courier service, or if sent by fax (provided that the fax is promptly confirmed by telephone confirmation thereof), to the person at the address or fax number set forth below, or such other address or fax number as may be designated in writing hereafter, in the same manner, by such person:

Section 14.02. Expenses. Except as otherwise provided herein, all costs and expenses incurred in connection with this Agreement shall be paid by the party incurring such cost or expense; provided, however, that Purchaser shall pay the full amount of any fees associated with filings made under the HSR Act and any Competition Law.

Section 14.03. Projections. In connection with Purchaser’s investigation of the Purchased Assets, the Japan Assets the Assumed Liabilities, the Japan Liabilities and the Business, Purchaser may have received, or may receive, from Seller, the Selling Affiliate and/or their respective representatives certain projections and other forecasts for the Business, and certain business plan and budget information. Purchaser acknowledges that (a) there are uncertainties inherent in attempting to make such projections, forecasts, plans and budgets, (b) Purchaser is familiar with such uncertainties, (c) Purchaser is taking full responsibility for making its own evaluation of the adequacy and accuracy of all estimates, projections, forecasts, plans and budgets so furnished to it, and (d) Purchaser will not assert any claim against Seller, the Selling Affiliate or any of their respective representatives, or hold Seller or any such other Persons liable, with respect thereto. Accordingly, Purchaser acknowledges that Seller makes no representation or warranty with respect to such estimates, projections, forecasts, plans or budgets and that Seller makes only those representations and warranties explicitly set forth in Article V.

Section 14.04. Specific Performance. Each party hereto acknowledges and agrees that the other party hereto could be irreparably damaged in the event any of the covenants contained in this Agreement are not performed in accordance with their specific terms or are otherwise breached. Accordingly, each party agrees that the other party will be entitled to seek an injunction or injunctions to enforce specifically such covenants in any action instituted in the courts of the State of Delaware.

Section 14.05. Fulfillment of Obligations. Any obligation of any party to any other party under this Agreement, which obligation is performed, satisfied or fulfilled by an Affiliate of such party, shall be deemed to have been performed, satisfied or fulfilled by such party.

Section 14.06. Entire Agreement. This Agreement (including all Exhibits and Schedules hereto) constitutes the entire agreement between the parties with respect to the subject matter of this Agreement and supersedes all prior agreements and understandings, both oral and written, between the parties with respect to the subject matter of this Agreement, except for the Confidentiality Agreement which will remain in full force and effect for the term provided therein.

Section 14.07. Amendments and Waivers. Any provision of this Agreement may be amended or waived if, but only if, such amendment or waiver is in writing and is signed, in the case of an amendment, by each party to this Agreement, or in the case of a waiver, by the party against whom the waiver is to be effective. No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

Section 14.08. Successors and Assigns; Third Party Beneficiaries. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns; provided that, except as set forth below, neither party may assign, delegate or otherwise transfer any of its rights or obligations under this Agreement without the prior written consent of the other party hereto. Notwithstanding the preceding sentence, Purchaser may assign, in its sole discretion, any of or all its rights, interests and obligations under this Agreement to one or more direct or indirect wholly-owned subsidiaries of

Purchaser (including designating any such entity or entities to act as Purchaser(s) hereunder), but no such assignment shall relieve Purchaser of any of its obligations under this Agreement if its transferee does not perform such obligations. Any assignment in contravention of this provision shall be null and void. This Agreement shall not confer any rights or benefits upon any Person other than the parties hereto and their respective successors and permitted assigns, except to the extent otherwise expressly provided herein.

Section 14.09. Severability. The provisions of this Agreement shall be deemed severable and the invalidity or unenforceability of any provision shall not affect the validity or enforceability of the other provisions hereof. If any provision of this Agreement, or the application thereof to any Person or any circumstance, is invalid or unenforceable, (a) a suitable and equitable provision shall be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision and (b) the remainder of this Agreement and the application of such provision to other Persons or circumstances shall not be affected by such invalidity or unenforceability, nor shall such invalidity or unenforceability affect the validity or enforceability of such provision, or the application thereof, in any other jurisdiction.

Section 14.10. No Recourse. No past, present or future director, officer, employee, incorporator, member, partner, individual stockholder, agent, attorney or representative of Guarantor, Purchaser or Seller or any of their respective Affiliates (other than, in the case of the Selling Affiliate, Seller) shall have any liability for any Liabilities of Guarantor, Purchaser or Seller or any of their respective Affiliates under this Agreement or for any claim based on, in respect of or arising out of the transactions contemplated hereby.

Section 14.11. Interpretation. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereof,” “herein” and “herewith” and words of similar import shall, unless otherwise stated, be construed to refer to this Agreement as a whole and not to any particular provision of this Agreement, and “Article,” “Section,” “clause,” “Exhibit” and “Schedule” references are to the Articles, Sections, clauses, Exhibits and Schedules of this Agreement unless otherwise specified. The captions, heading references and table of contents herein are included for convenience of reference only and shall be ignored in the construction or interpretation hereof. The phrases “the date hereof,” “the date of this Agreement” and phrases of similar import, unless the context otherwise requires, shall be deemed to refer to the date set forth in the Preamble to this Agreement. The word “extent” in the phrase “to the extent” shall mean the degree to which a subject or other thing extends, and such phrase shall not mean simply “if.” The parties hereto have participated jointly in the negotiation and drafting of this Agreement. If any ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any of the provisions of this Agreement.

Section 14.12. Disclosure Schedule. The Disclosure Schedule constitutes an integral part of this Agreement and is hereby incorporated herein. There may be included in the Disclosure Schedule and elsewhere in this Agreement items and information that are not “material,” and such inclusion shall not be deemed to be an acknowledgment or agreement that any such item or

information (or any non-disclosed item or information of comparable or greater significance) is “material,” or to affect the interpretation of such term for purposes of this Agreement. Disclosures included in any section of the Disclosure Schedule shall be considered to be made for purposes of all other sections of the Disclosure Schedule to the extent that the relevance of any such disclosure to any other section of the Disclosure Schedule is readily apparent on its face. Matters reflected in the Disclosure Schedule are not necessarily limited to matters required by this Agreement to be disclosed in the Disclosure Schedule. No disclosure in the Disclosure Schedule relating to a possible breach or violation of any Contract or Law shall be construed as an admission or indication that such breach or violation exists or has occurred. Any capitalized term used in the Disclosure Schedule and not otherwise defined therein shall have the meaning given to such term in this Agreement. Any headings set forth in the Disclosure Schedule are for convenience of reference only and shall not affect the meaning or interpretation of any of the disclosures set forth in the Disclosure Schedule.

Section 14.13. Governing Law; Jurisdiction. This Agreement and the transactions contemplated hereby, and all disputes between the parties hereto under or relating to this Agreement or the transactions contemplated hereby, whether in contract, tort or otherwise, shall be governed by, and construed and enforced in accordance with, the internal Laws of the State of Delaware, without regard to any conflicts of law rules thereof that would result in the application of the Law of any other State. The Delaware Court of Chancery sitting in Wilmington, Delaware (and if the Delaware Court of Chancery shall be unavailable, any Delaware state court and the Federal court of the United States of America sitting in the State of Delaware) will have exclusive jurisdiction over any and all disputes among the parties hereto, whether at law or in equity, based upon, arising out of or relating to this Agreement and the transactions contemplated hereby or the facts and circumstances leading to its execution and delivery, whether in contract, tort or otherwise. Each of the parties hereto irrevocably consents to and agrees to submit to the exclusive jurisdiction of such courts, agrees that process may be served upon them in any manner authorized by the Laws of the State of Delaware, and hereby waives, and agrees not to assert in any such dispute, to the fullest extent permitted by applicable Law, any claim that (a) such party is not personally subject to the jurisdiction of such courts, (b) such party and such party’s property is immune from any legal process issued by such courts or (c) any litigation commenced in such courts is brought in an inconvenient forum. EACH OF THE PARTIES HERETO IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OUTSIDE THE TERRITORIAL JURISDICTION OF THE COURTS REFERRED TO IN THIS SECTION 14.14 IN ANY ACTION OR PROCEEDING UNDER OR RELATING TO THIS AGREEMENT OR THE FACTS AND CIRCUMSTANCES LEADING TO ITS EXECUTION AND DELIVERY BY MAILING COPIES THEREOF BY REGISTERED UNITED STATES MAIL, POSTAGE PREPAID, RETURN RECEIPT REQUESTED, TO ITS ADDRESS AS SPECIFIED IN OR PURSUANT TO SECTION 14.01. HOWEVER, THE FOREGOING SHALL NOT LIMIT THE RIGHT OF A PARTY TO EFFECT SERVICE OF PROCESS ON ANY OTHER PARTY BY ANY OTHER LEGALLY AVAILABLE METHOD. Nothing in this Section 14.14 shall limit the jurisdictions in which a judgment may be enforced.

Section 14.14. WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

Section 14.15. Counterparts; Electronic Transmission. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement shall become effective when each party hereto shall have received a counterpart hereof signed by the other party hereto. Counterparts delivered by electronic transmission shall be deemed to be originally signed counterparts.

Section 15.01. Guarantee and Indemnity. Guarantor unconditionally and irrevocably:

(a) guarantees to Seller and the Selling Affiliate the performance of all obligations of Purchaser under this Agreement;

(b) agrees that if and each time that Purchaser fails to perform its obligations under this Agreement, Guarantor must on demand (without requiring Seller and the Selling Affiliate first to take steps against Purchaser or any other person) perform such obligations as if it were the principal obligor in respect thereof; and

(c) agrees as principal debtor and primary obligor to indemnify Seller and the Selling Affiliate against, and to pay to Seller or the Selling Affiliate, as appropriate, on demand an amount equal to all Losses directly or indirectly incurred or suffered by Seller or the Selling Affiliate arising out of or in connection with any non-performance of any kind by Purchaser under this Agreement.

Section 15.02. Obligations Not Affected by Certain Matters. The obligations of Guarantor under this Agreement are not affected by any matter or thing which but for this provision might operate to affect or prejudice those obligations, including:

(a) any time or indulgence granted to, or composition with, Purchaser or any other Person;

(b) the taking, variation, renewal or release of, or neglect to perfect or enforce this Agreement, or any right, guarantee, remedy or security from or against Purchaser or any other Person;

(d) any unenforceability or invalidity of any obligation of Purchaser, so that this Agreement must be construed as if there were no such unenforceability or invalidity.

Section 15.03. Purchaser’s Actions to Bind Guarantor. Any agreement, waiver, consent or release given by Purchaser shall bind Guarantor.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed by their respective authorized officers as of the day and year first above written.
