2.5 Certificate of Incorporation and Bylaws of the Surviving Corporation. At the Effective Time, (i) the Certificate of Incorporation of the Company as in effect immediately prior to the Effective Time shall be the Certificate of Incorporation of the Surviving Corporation until thereafter amended as provided by law and such Certificate of Incorporation, and (ii) the Bylaws of the Company as in effect immediately prior to the Effective Time shall be the Bylaws of the Surviving Corporation until thereafter amended as provided by law, the Certificate of Incorporation of the Surviving Corporation or such Bylaws.

Each certificate representing outstanding shares of the Merger Sub Stock shall at the Effective Time represent an equal number of shares of Surviving Corporation Stock.

(b) Cancellation of Certain Shares of Company Common Stock.

(c) Conversion of the Shares. Each of the Shares shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and each holder of a certificate that immediately prior to the Effective Time represented the Shares shall thereafter cease to have any rights with respect thereto, except for the right to receive the Merger Consideration with respect to the Shares formerly represented thereby.

3.2 Waiver of Appraisal Rights. The Shareholder hereby acknowledges that it has voted the Shares in favor of the Merger and has irrevocably waived, and will not seek to assert, any right to an appraisal of the Shares under the DGCL.

4. Adjustments to Foreign Subsidiary Purchase Prices and Merger Consideration.

4.1 Procedure for Determining Adjustments to each Foreign Subsidiary Purchase Price and the Merger Consideration. For the purpose of determining adjustments, if any, to each Foreign Subsidiary Purchase Price and the Merger Consideration, within 90 days following, in the case of Foreign Subsidiary Purchase Price adjustments, the Share Purchase Closing, and in the case of Merger Consideration adjustments, the Merger Closing, the Parent will deliver to the Shareholder: (i) a balance sheet of each Foreign Subsidiary and a consolidated balance sheet of the Company and the Remaining Subsidiaries as of the close of business on the Share Purchase Closing Date or Merger Closing Date, as applicable (each, a “Closing Balance Sheet”), each of which shall present fairly, in all material respects, the consolidated financial condition of the Persons subject thereof and be prepared (x) in accordance with GAAP, as applied in the preparation of the 2004 Balance Sheet (including the adjustments for GAAP presentation set forth in Schedule 4.1), and (y) using the line items set forth in the form of Closing Balance Sheet set forth in Schedule 4.1, and (ii) in the case of each Foreign Subsidiary Purchase Price adjustment, a statement showing the calculation of final Working Capital for the applicable Foreign Subsidiary (each a “Foreign Subsidiary Final Working Capital”), and in the case of the

Merger Consideration adjustment, a statement showing the calculation of final Working Capital for the Company and the Remaining Subsidiaries (the “Company Final Working Capital”) (each a “Closing Statement”) and (iii) customary Company management representation letters addressed to the Shareholder.

(a) During the 30-day period following the Shareholder’s receipt of each Closing Balance Sheet and each Closing Statement, the Shareholder shall be given full access to the working papers of the Parent and the Company Group and their respective independent auditors as well as to the personnel, properties, books, records, schedules, analyses and working papers of the Company Group involved in or relating to the preparation of each Closing Balance Sheet and each Closing Statement. Each Closing Balance Sheet and each Closing Statement shall become final and binding upon the parties on the 31st day following the Shareholder’s receipt thereof unless the Shareholder gives written notice of its disagreement with any such Closing Balance Sheet and any such Closing Statement (the “Notice of Disagreement”) to the Parent prior to such date. The Notice of Disagreement shall specify in reasonable detail the nature of any such disagreement. If a Notice of Disagreement is received by the Parent in a timely manner, then each disputed Closing Balance Sheet and Closing Statement (each as revised in accordance with clause (x) or (y) below) shall become final and binding upon the parties upon the earlier of (x) the date on which the Shareholder and the Parent resolve in writing any applicable differences they have with respect to the matters specified in the Notice of Disagreement and (y) the date on which any applicable disputed matters are finally resolved in writing by the Accounting Firm.

(b) During the 30-day period following the delivery of a Notice of Disagreement in compliance with clause (a) above, the Shareholder and the Parent shall seek in good faith to resolve any differences they may have with respect to the matters specified in the Notice of Disagreement. During such period, each of the Parent and its independent auditors and the Shareholder and its independent auditors shall have full access to the other’s working papers and to the personnel, properties, books, records, schedules, analyses and working papers of the Shareholder relating to the preparation of the Notice of Disagreement. If, at the end of such 30-day period, the Shareholder and the Parent shall not have resolved such differences, the Shareholder and the Parent shall submit to the national office of Deloitte & Touche LLP or, if such firm is unwilling or unable to serve, the national office of any other “big four” accounting firm selected by the Parent that has no material relationship with the Parent, the Shareholder or their respective Affiliates (the “Accounting Firm”) for review and resolution of any and all matters that remain in dispute and that were properly included in the Notice of Disagreement. The Shareholder and the Parent shall use their respective commercially reasonable efforts to cause the Accounting Firm to render a decision resolving the matters in dispute within 30 days following the submission of such matters to the Accounting Firm. The Shareholder and the Parent agree that judgment may be entered upon the determination of the Accounting Firm in any court having jurisdiction over the party against which such determination is to be enforced. The cost of any review and resolution (including the fees and expenses of the Accounting Firm and reasonable fees and expenses of legal counsel of the parties) pursuant to this Section 4.1(b) shall be borne by the Shareholder and the Parent in inverse proportion as they may prevail on matters

resolved by the Accounting Firm, which inverse proportionate allocations shall also be determined by the Accounting Firm at the time the determination of the Accounting Firm is rendered on the merits of the matters submitted.

4.2 Foreign Subsidiary Purchase Price and Merger Consideration Adjustment. As soon as practicable after each Foreign Subsidiary Final Working Capital and the Company Final Working Capital have been determined pursuant to Section 4.1 (but in any event within three Business Days after each such determination), the Parent, if any applicable Foreign Subsidiary Final Working Capital or the Company Final Working Capital, as the case may be, exceeds the applicable Foreign Subsidiary Target Working Capital or the Company Target Working Capital, respectively, or the Shareholder, if any applicable Foreign Subsidiary Final Working Capital or the Company Final Working Capital, as the case may be, is less than the applicable Foreign Subsidiary Target Working Capital or the Company Target Working Capital, respectively, shall deliver to such other party, by wire transfer of immediately available funds to the account specified by the recipient, an amount equal to the sum of (i) the amount of each such excess plus (ii) interest on the net amount of such excess from the applicable Closing Date through but excluding the date on which such net amount is paid at a rate per annum equal to the average over such period of the Federal funds discount rate as published in The Wall Street Journal. Notwithstanding the foregoing, with the consent of the parties, not to be unreasonably withheld, all such adjustments shall be aggregated such that one party shall make a single aggregated payment to the other party.

5. Representations and Warranties of the Shareholder and the Company. Except as set forth in the Schedules hereto, the Shareholder and the Company, jointly and severally, represent and warrant to the Parent and Merger Sub as follows:

5.1 Corporate Status and Authority. The Shareholder is a corporation duly incorporated, validly existing and in good standing under the laws of the State of New York and has the corporate power and authority to own the Shares and to execute and deliver this Agreement and perform its obligations hereunder. The execution, delivery and performance of this Agreement have been duly authorized by the Board of Directors of the Shareholder, which approval constitutes all necessary corporate action on the part of the Shareholder for such authorization. This Agreement has been duly executed and delivered by the Shareholder and constitutes the valid and binding obligation of the Shareholder, enforceable against the Shareholder in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, reorganization, insolvency, fraudulent conveyance, moratorium, receivership or similar laws affecting creditors’ rights generally and by general principles of equity (whether considered at law or in equity).

5.2 No Conflicts, Consents and Approvals.

(a) Except as set forth in Schedule 5.2(a), neither the execution, delivery or performance of this Agreement by the Shareholder or the Company nor the consummation of the transactions contemplated hereby will result in (i) any conflict with the certificate of incorporation or by-laws of the Shareholder or any member of the Company Group, (ii) subject to obtaining the consents, approvals and authorizations and making the filings referred to in Section 5.2(b), any breach or violation of or default under any applicable statute, regulation,

judgment, order or decree of any Governmental Authority or any mortgage, agreement, indenture or any other instrument to which the Shareholder or any member of the Company Group is a party or by which any of them or their respective properties or assets are bound, (iii) any Person being granted (with or without notice of lapse of time or both) any right of termination, cancellation, acceleration or modification in or with respect to, any Contract or other agreement to which the Shareholder or any member of the Company Group is a party or by which any of them or their respective properties or assets are bound, or (iv) the creation or imposition of any liens, security interests, adverse claims, charges or encumbrances (collectively, “Liens”) on the Shares or the assets of any member of the Company Group, except for Permitted Liens, except, in the case of clauses (ii) and (iii), as would not reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect.

(b) Except as set forth in Schedule 5.2(b) and for filings, consents or approvals that are required with respect to the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby will not require the Shareholder or any member of the Company Group to obtain any material consent, approval or authorization of or make any filing with any Governmental Authority or any other Person.

5.3 Corporate Status of the Company; Authority.

(a) The Company has all requisite corporate power and authority to conduct its business and to own or lease its properties, as now conducted, owned or leased. The Company is duly qualified and, where such concept is recognized, is in good standing as a foreign corporation duly authorized to do business in all jurisdictions, in each case, in all material respects. The Company does not have any equity interest or investment in any Person other than as set forth in Schedule 5.3 or Schedule 5.5.

(b) The Company is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware and has the corporate power and authority to execute and deliver this Agreement and perform its obligations hereunder. The execution, delivery and performance of this Agreement have been duly authorized by the Board of Directors of the Company, which approvals constitute all necessary corporate action on the part of the Company for such authorization. This Agreement has been duly executed and delivered by the Company and constitutes the valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, reorganization, insolvency, fraudulent conveyance, moratorium, receivership or similar laws affecting creditors’ rights generally and by general principles of equity (whether considered at law or in equity).

5.4 The Shares. The authorized, issued and outstanding capital stock of the Company consists solely of the Shares. The Shares are owned by the Shareholder, free and clear of all Liens other than Permitted Liens. The Shares have been duly authorized and validly issued and are fully paid and non-assessable.

In the case of Taxes that are payable with respect to a taxable period that begins before the Share Purchase Closing Date with respect to the Foreign Subsidiaries or before the Merger Closing Date with respect to the Company and the Remaining Subsidiaries and ends after the Share Purchase Closing Date or Merger Closing Date, as applicable, the portion of any such Tax that is allocable to the portion of the period ending on the Share Purchase Closing Date or Merger Closing Date, as applicable, shall be deemed equal to the amount which would be payable if the taxable year ended at the time of the Share Purchase Closing or Merger Closing, as applicable, and the Parent and the Surviving Corporation shall prepare books and working papers (including a closing of the books) that will demonstrate the income and activities of the applicable members of the Company Group for the period ending at the time of the Share Purchase Closing or Merger Closing, as applicable, and such post-closing partial period.

(ii) The Parent’s Responsibility.

(including any consolidated federal income Tax Return filed by the Surviving Corporation) any transactions or events by or relating to any relevant member of the Company Group after the Share Purchase Closing with respect to the Foreign Subsidiaries and after the Merger Closing with respect to the Company and Remaining Subsidiaries. Any such Tax Returns with respect to which the Parent or the Surviving Corporation is responsible for preparing and filing pursuant to this Section 7.4(b)(ii) that include the taxable periods (or portions thereof) ending on or prior to the Share Purchase Closing Date with respect to the Foreign Subsidiaries and on or prior to the Merger Closing Date with respect to the Company and Remaining Subsidiaries shall, insofar as they relate to any member of the Company Group, (x) be on a basis consistent with the last previous such Tax Returns filed in respect of any such member of the Company Group and (y) be submitted to the Shareholder for its review and approval at least 30 Business Days prior to the filing date, such approval not to be unreasonably withheld.

In the event that, after having made inquiry of the Parent and the Surviving Corporation, the Shareholder shall have reason to believe that such tax packages, foreign reporting packages and other information will not be provided to the Shareholder on a timely basis, the Shareholder shall have the right, at the Parent’s expense, to retain PricewaterhouseCoopers LLP, or other accounting firm of its choice, to prepare such packages and information and submit the same to the Shareholder. In the event the Shareholder exercises its rights under the preceding sentence, the Parent and the Surviving Corporation shall cause the Company Group to fully cooperate with and provide all necessary information and access to PricewaterhouseCoopers LLP or such other accounting firm as may be necessary to enable it to accurately and completely prepare such packages and information for submission to the Shareholder.

(iv) Amended Returns.

such amended Tax Return (or claim for a refund) prior to the filing thereof (which consent shall not be unreasonably withheld or delayed).

(c) Refunds. The Shareholder shall be entitled to retain, or receive immediate payment from any member of the Company Group or the Parent or the Surviving Corporation of, (i) any Tax refund, excluding any Tax refunds that were taken into account in Current Assets for purposes of the adjustments in Section 4, but including, without limitation, refunds arising by reason of amended returns filed after the Share Purchase Closing Date or Merger Closing Date, as the case may be, and refunds or other distributions of any amounts deposited in connection with the tax litigation described in Schedule 5.14 under the heading “Tax Litigation”, or (ii) credit of any taxes (plus any interest thereon received with respect thereto from the applicable taxing authority or Governmental Authority) relating to any member of the Company Group for which the Shareholder is responsible under Section 7.4(a) or has otherwise paid or caused to be paid. In addition, any reduction of Taxes (“Reduced Taxes”) (i) due with respect to the assets or business of any member of the Company Group for any period or partial period ending after the Share Purchase Closing Date with respect to the Foreign Subsidiaries or the Merger Closing Date with respect to the Company and the Remaining Subsidiaries that is attributable to an adjustment on audit by a taxing authority requiring any member of the Company Group to capitalize expenses or otherwise defer deductions that were currently deducted on a Tax Return as originally filed for periods ending on or prior to the Share Purchase Closing Date or the Merger Closing Date, as the case may be, shall be credited to the Shareholder, and the Parent or any member of the Company Group shall pay over such Reduced Taxes to the Shareholder promptly after the receipt of any refund of Taxes attributable thereto or the payment of any Reduced Tax or the reporting of any Tax liability in an amount reflecting such Reduced Taxes, less the reasonable expenses incurred by the Parent or the Surviving Corporation, if any, to amend any Tax Returns in order to pursue such refund, or (ii) due with respect to the assets or business of the Company Group, for any period or partial period ending on or before the Share Purchase Closing Date with respect to the Foreign Subsidiaries or the Merger Closing Date with respect to the Company and the Remaining Subsidiaries that is attributable to an adjustment on audit by a taxing authority requiring any member of the Company Group to deduct expenses that were capitalized or accelerate anticipated deductions, in each case, on a Company Group Tax Return relating to periods or portions thereof ending on or prior to the Share Purchase Closing Date or the Merger Closing Date, as the case may be, shall be credited to the Parent and the Shareholder shall pay over such Reduced Taxes to the Parent promptly after the receipt of any refund of Taxes attributable thereto, less any reasonable expenses incurred by the Shareholder, if any, to amend any Tax Returns in order to pursue such refund. Any dispute with respect to Reduced Taxes shall be resolved by the Tax Dispute Accountants, and any such determination by the Tax Dispute Accountants shall be final. The Parent shall be entitled to the benefit of any other refund or credit of Taxes (plus any interest thereon received with respect thereto from the applicable taxing authority) relating to any member of the Company Group. The Parent, the Shareholder and the Surviving Corporation shall reasonably cooperate, and the Parent shall cause the Company Group and their other Affiliates to reasonably cooperate, with the Shareholder with respect to claiming of any refund or credit referred to in this Section 7.4(c), including discussing potentially available refunds or credits and preparing and filing any amended Tax Return or other claim for a refund except to the extent the Parent reasonably determines that the filing of such amended Tax Return or other claim for a refund would have a Material Adverse Effect on the Company Group, taken as a whole.

(d) Audits. Each of the Parent, Merger Sub, Company and Shareholder shall promptly notify the other parties in writing within 10 Business Days from its receipt of notice of (i) any pending or threatened federal, state, local or foreign Tax audits or assessments of any member of the Company Group, so long as any taxable periods (or portions thereof) ending on or prior to the Share Purchase Closing Date or Merger Closing Date, as applicable, remain open, and (ii) any pending or threatened federal, state, local or foreign Tax audits or assessments of the Parent, Merger Sub, Company or the Shareholder which may affect the Tax liabilities of any member of the Company Group, in each case for taxable periods (or portions thereof) ending on or prior to the Share Purchase Closing Date or Merger Closing Date, as applicable, provided that the failure of one party to timely notify the other parties of any such Tax audit or assessment pursuant to this sentence shall not increase, decrease or otherwise affect the indemnity right or obligation of either party, so long as such failure does not materially prejudice such other party. Notwithstanding the foregoing and provided the Shareholder acknowledges potential liability therefor, the Shareholder shall have the right to represent the interests of the applicable member of the Company Group and control the conduct and disposition of any Tax audit or administrative or court proceeding relating to Taxes for any taxable periods (or portions thereof) ending on or prior to the Share Purchase Closing Date or Merger Closing Date, as applicable, and for which the Shareholder may be responsible hereunder, and the Parent and the Surviving Corporation shall have the right to consult with the Shareholder during such proceedings at their own expense.

Such arrangements are referred to herein as the “Credit Support Arrangements.” At or prior to the Share Purchase Closing in the case of the Foreign Subsidiaries and at or prior to the Merger Closing in the case of the Company and Remaining Subsidiaries, the Parent shall or shall cause the Merger Sub to (i) obtain replacement Credit Support Arrangements or (ii) repay, or cause the repayment of, all debt and other obligations to which such Credit Support Arrangements relate (and cause the cancellation of such Credit Support Arrangements) or arrange for the Parent or one of its Subsidiaries to be substituted as the obligor thereof.

7.9 Noncompetition. The Shareholder will, for a period of three years from the Merger Closing Date, refrain from, either alone or in conjunction with any other Person, directly or indirectly through its current Affiliates, engaging in any business or activity that involves in any material respect the production and supply of carbon black as currently conducted by the Shareholder through the Company (such business or activity, a “Competing Business”). The Shareholder’s ownership of (i) any Person that derives less than 10% of its total annual revenues from a Competing Business or (ii) less than 1% of the outstanding voting shares of any publicly held company, which would otherwise be prohibited by this Section 7.9, shall not constitute a violation of this Section 7.9.

7.10 Appraisals. Promptly, and in any event within 45 days from the date hereof, the Parent shall deliver to the Shareholder appraisals reasonably satisfactory to the Shareholder, which may be prepared by the Parent, supporting the purchase price set forth in Schedule 1.3 for each Foreign Subsidiary and the amount of the Merger Consideration allocated to the Company and each Remaining Subsidiary as set forth in Schedule 7.10.

7.11 Certain Foreign Conversions. As promptly as practicable, the Shareholder shall use its good faith efforts to cause (i) Columbian Carbon Spain, Ltd. to convert into a Sociedad de Responsabilidad Limitada under the laws of Spain, and (ii) Columbian Chemicals Canada, Ltd. to convert into an unlimited liability company under Canadian law (together, the “Foreign Conversions”)

8. Employees and Employee Benefit Plans.

8.1 Compensation and Benefits of Company Employees. The employees of the Company Group (including any employee who is on an approved paid or unpaid leave of absence or salary continuance or short-term disability leave (as the case may be) and any other employee who has the legal or contractual right to be employed by any member of the Company Group) shall be referred to as “Company Employees.” Effective as of the Share Purchase Closing with respect to the Foreign Subsidiaries and as of the Merger Closing with respect to the Company and Remaining Subsidiaries, the Parent shall, or shall cause the Surviving Corporation or a member of the Company Group to, employ or continue to employ all Company Employees represented by a union in accordance with the terms and conditions set forth in any applicable collective bargaining agreements, including without limitation those listed in Schedule 5.10.1, and all non-union-represented Company Employees in accordance with this Section 8. From and for one year after the Share Purchase Closing Date with respect to the Foreign Subsidiaries and from and for one year after the Merger Closing Date with respect to the Company and Remaining Subsidiaries, the Parent will, or will cause the Surviving Corporation or a member of the Company Group to, provide or continue to provide each Company Employee with employee compensation and benefits and other terms and conditions of employment that are in the good faith opinion of the Parent substantially comparable in the aggregate to the compensation and benefits and terms and conditions provided to each such Company Employee by the Shareholder or its Affiliates, as applicable, immediately prior to the Share Purchase Closing or Merger Closing, as the case may be. Notwithstanding the foregoing, this Section 8.1 shall not be construed as a guarantee of continued employment of the Company Employees for a specified period. Except to the extent provided in this Section 8 or as otherwise provided in this Agreement, from and after the Share Purchase Closing or Merger Closing, as the case may be, the Parent shall, or shall cause the Surviving Corporation or applicable member of the Company Group to, honor, pay, perform and satisfy any and all liabilities, obligations and responsibilities to or in respect of each Company Employee arising under the terms of or in connection with any applicable Plan, any applicable employment, consulting, severance, retention, change of control or similar agreement or arrangement, in each case as in effect immediately prior to the Share Purchase Closing or Merger Closing, as applicable, excluding (x) any Plans or applicable agreements or arrangements maintained by the Shareholder and/or its Affiliates (other than any member of the Company Group) after the Share Purchase Closing or Merger Closing, as applicable, and (y) any claims or liabilities arising under or incurred with respect to any Plan or applicable agreements or arrangements based on events occurring prior to the Share Purchase Closing or Merger Closing, as applicable. Except to the extent provided in this Section 8 or as otherwise provided in this Agreement, the Shareholder shall assume and indemnify and hold the Company Group harmless against liabilities, obligations and responsibilities described in clauses (x) or (y) of the preceding sentence. For all purposes under all compensation and benefit Plans applicable to Company Employees after the Share Purchase Closing or Merger Closing, as applicable, the Parent shall, or shall cause the Merger Sub or applicable member of the Company

Group, as applicable, to continue to treat all service by Company Employees with the Shareholder, the Company and any and all Subsidiaries or Affiliates of the Shareholder or the Company before the Share Purchase Closing or Merger Closing, as the case may be, as service with the Parent, Merger Sub or the Company or their Affiliates to the same extent as recognized by the Shareholder, the Company and all Subsidiaries or Affiliates of the Shareholder or the Company prior to the Share Purchase Closing or Merger Closing, as the case may be; provided that the foregoing shall not apply to the extent that its application would result in a duplication of benefits.

8.1.1 Plan Funding Statements.

(a) Without duplication for purposes of determining any Foreign Subsidiary Purchase Prices and Merger Consideration, 100% of the Unfunded PBO with respect to any Plan listed on Schedule 8.1.1-A plus 100% of the Unfunded APBO with respect to any Plan listed on Schedule 8.1.1-B shall be treated as Indebtedness.

(b) The Unfunded PBO and Unfunded APBO with respect to any Plan described in Schedules 8.1.1-A and 8.1.1-B will be set forth in a Plan Funding Statement delivered by the Shareholder to the Parent within 30 days following the Share Purchase Closing Date or Merger Closing Date, as applicable. Upon receipt of the relevant Plan Funding Statement, the Parent shall have the right to review and confirm the accuracy of the calculations. The Parent shall deliver a Plan Notice of Disagreement to the Shareholder within 45 calendar days after receiving the relevant Plan Funding Statement if the Parent disagrees with the Shareholder’s calculation of Unfunded PBO or Unfunded APBO, which Plan Notice of Disagreement will initiate the Dispute Resolution Process set forth in Section 8.1.2. If the resolution of any dispute regarding a Plan Funding Statement is resolved prior to the adjustment, if any, of the Foreign Subsidiary Purchase Prices and the Merger Consideration pursuant to Section 4.2, then the adjusted Unfunded PBO or Unfunded APBO will be used in calculating any such adjustment. If the resolution of any disputes regarding a Plan Funding Statement is delayed on account of the Dispute Resolution Process and thus cannot be finalized until after the applicable adjustment, if any, is determined pursuant to Section 4.2, then the amount of the applicable Unfunded PBO or Unfunded APBO shall be paid by the Shareholder to the Parent in immediately available funds by wire transfer to an account specified by the Parent within 15 days from the completion of the Dispute Resolution Process.

(c) For purposes of Sections 8.1.1 and 8.1.2: (i) “Plan Funding Statement” shall mean a statement prepared by a nationally recognized actuarial firm selected by the Shareholder setting forth the amount of the Unfunded PBO and/or Unfunded APBO, if any, with respect to each Plan, as well as all the data (and supporting calculations) used to determine these amounts, (ii) “PBO” for each applicable Plan shall mean the projected benefit obligation, calculated in accordance with GAAP (Financial Accounting Statements 87, 106, 112 or other accounting statements, as applicable) and the assumptions and methodologies set forth on the relevant portion of Schedule 8.1.1-A, for each such Plan as of the Share Purchase Closing Date or Merger Closing Date, as applicable, (iii) “Unfunded PBO” shall mean the excess, if any, of the PBO for each Plan over the fair value, as of the last day of the month preceding the month in which the Share Purchase Closing or Merger Closing, as applicable, occurs, of the assets of such Plan and other assets identified on Schedule 8.1.1-A, as of the Share Purchase Closing Date or Merger

Closing Date, as applicable, (iv) “APBO” for each applicable Plan shall mean the accumulated post-employment benefit obligation, calculated in accordance with GAAP (Financial Accounting Statements 106, 112 or other accounting statements, as applicable) and the assumptions and methodologies set forth on the relevant portion of Schedule 8.1.1-B, for each such Plan as of the Share Purchase Closing Date or Merger Closing Date, as applicable, (v) “Unfunded APBO” shall mean the excess, if any, of the APBO for each Plan over the fair value, as of the last day of the month preceding the month in which the Share Purchase Closing or Merger Closing, as applicable, occurs, of the assets of such Plan and other assets identified on Schedule 8.1.1-B, as of the Share Purchase Closing Date or Merger Closing Date, as applicable, and (vi) “Plan Notice of Disagreement” shall mean a written statement setting forth in reasonable detail the basis for a dispute. For the avoidance of doubt, Unfunded PBO and Unfunded APBO cannot be less than zero. Further, Unfunded PBO and Unfunded APBO will be determined on a plan by plan basis in accordance with the Plan Funding Statement.

8.1.2 Dispute Resolution Process. During the 10 calendar day period immediately following the delivery of a Plan Notice of Disagreement, the Parent and the Shareholder shall seek in good faith to resolve any differences that they may have with respect to any matter specified in the Plan Notice of Disagreement. If at the end of such 10 calendar day period the Parent and the Shareholder have been unable to agree upon a Plan Funding Statement, then the Parent and the Shareholder shall submit to a nationally recognized, independent actuarial firm (selected by the parties) for review and resolution any and all matters that remain in dispute with respect to the Plan Notice of Disagreement. The Parent and the Shareholder shall use commercially reasonable efforts to cause the independent actuarial firm to deliver a final Plan Funding Statement within 20 calendar days from such submission (which determination shall be binding on the parties hereto), and the cost of such independent actuarial firm shall be split equally between and paid by the Parent and the Shareholder. During the 20 calendar day review by the independent actuarial firm, the Parent and the Shareholder will each make available to the independent actuarial firm such individuals and such information, books and records as may be reasonably required (including of the Company and Merger Sub) by the independent actuarial firm to make its final determination.

8.1.3 Certain Company Benefits. Effective as of the Share Purchase Closing with respect to Foreign Subsidiaries and as of the Merger Closing with respect to the Company and Remaining Subsidiaries, the Shareholder or one of its Affiliates shall cause each Company Employee (other than Covered Employees as defined in Section 8.1.12) and Former Employee who participates in the Phelps Dodge Retirement Plan or the Phelps Dodge Corporation Supplemental Retirement Plan to cease to accrue any additional benefits thereunder. Effective as of the Share Purchase Closing or Merger Closing, as applicable, the Shareholder shall, or shall cause one of its Affiliates other than any member of the Company Group to, assume or maintain sponsorship of and be solely responsible for, all benefits accrued under the Phelps Dodge Retirement Plan and the Phelps Dodge Corporation Supplemental Retirement Plan.

8.1.4 Filings and Records. The Shareholder, the Parent, the Merger Sub and the Company Group shall cooperate in making all appropriate filings required under the Code or ERISA and any applicable securities laws, implementing all appropriate communications with participants, maintaining and transferring appropriate records and taking all such other actions as may be necessary and appropriate to implement the provisions of this Section 8.

Without limiting the generality of the foregoing, effective as of the Share Purchase Closing or Merger Closing, as the case may be, the Company Group shall be responsible and liable for providing the appropriate COBRA notices to the relevant Company Employees and their beneficiaries who experience a “qualifying event” on or after the Share Purchase Closing or Merger Closing, as applicable, and for providing or continuing to provide coverage required under COBRA with respect to the relevant Company Employees and their beneficiaries who experience a “qualifying event” on or after the Share Purchase Closing or Merger Closing, as applicable, except with respect to any person participating in any Plans the Shareholder shall retain or assume on and after the Share Purchase Closing Date or Merger Closing Date, as applicable. The Shareholder shall retain liability and responsibility for all benefits requirements under COBRA with respect to Company Employees, Former Employees and their beneficiaries who experience a qualifying event prior to the Share Purchase Closing or Merger Closing, as applicable. If Company Employees participate in the welfare benefit plans of the Parent or its Affiliates after the Share Purchase Closing or Merger Closing, as the case may be, the Parent shall, or shall cause the Merger Sub or Company Group to, (i) cause any pre-existing conditions or limitations and eligibility waiting periods under any group health plans of the Parent or its Affiliates to be waived with respect to the Company Employees and their eligible dependents and (ii) give each Company Employee credit for the plan year in which the transition from the Shareholder’s or its Affiliates’ (other than the Company Group) plans to the Parent’s or its Affiliates’ plans occurs towards applicable deductibles and annual out-of-pocket limits for expenses incurred prior to the transition date; provided, that the foregoing shall not apply to the extent that its application would result in a

duplication of benefits. From and after the Share Purchase Closing or Merger Closing, as applicable, the Shareholder shall remain responsible for all claims of Former Employees and their eligible dependents and for claims of Company Employees and their eligible dependents incurred prior to the Share Purchase Closing Date or Merger Closing Date, as applicable, under those Plans that are maintained and sponsored by the Shareholder (other than liabilities under a cafeteria plan in which account balances have been transferred as described in this Section) and the Parent, Merger Sub and the Company Group shall be responsible for all liabilities incurred by any Company Employee and his/her eligible dependents under those Plans that are maintained by the Parent or its Affiliates on or after the Share Purchase Closing Date or Merger Closing Date, as applicable.

11.2.3 Indemnification Procedures. A party entitled to indemnification hereunder shall herein be referred to as an “Indemnitee.” A party obligated to indemnify an Indemnitee hereunder shall herein be referred to as an “Indemnitor.”

(a) If an Indemnitee receives notice of any claim or the commencement of any action by any third party that such Indemnitee reasonably believes may give rise to a claim for indemnification from an Indemnitor hereunder, and such Indemnitee intends to seek indemnification from such Indemnitor with respect thereto under this Section 11, such Indemnitee shall promptly provide written notice thereof to such Indemnitor. Such notice shall (i) specify in reasonable detail the basis on which indemnification is being asserted, (ii) provide a reasonable estimate of the amount of the Damages asserted therein, (iii) specify the provision or provisions of this Agreement under which such Damages are asserted and (iv) include copies of all notices and documents (including court papers) served on or received by the Indemnitee from such third party. Upon receipt of such notice, the Indemnitor shall be entitled to participate in such claim or action, to assume the defense thereof, and to settle or compromise such claim or action; provided that the Indemnitor shall not enter into any settlement that provides for injunctive or other non-monetary relief affecting the Indemnitee without the prior written consent of the Indemnitee, which consent shall not be unreasonably withheld or delayed. After notice to the Indemnitee of the Indemnitor’s election to assume the defense of such claim or action, the Indemnitor shall not be liable to the Indemnitee for any legal or other expenses subsequently incurred by the Indemnitee in connection with the defense thereof, provided that the Indemnitee shall have the right to employ counsel to represent it if either (x) such claim or action involves remedies other than monetary damages and such remedies, in the Indemnitee’s reasonable judgment, could have or reasonably be expected to have a Material Adverse Effect on such Indemnitee or (y) the Indemnitee has available to it one or more defenses or counterclaims that are inconsistent with one or more of the defenses or counterclaims alleged by the Indemnitor and which could be materially adverse to the Indemnitor, and in any such event the fees and expenses of such separate counsel shall be paid by the Indemnitee. If the Indemnitor does not elect to assume the defense of such claim or action within 45 days of the Indemnitee’s delivery of the notice and other documents that it is required to deliver to the Indemnitor in respect of such a

claim or action, the Indemnitee shall be entitled to assume the defense thereof. Unless it has been conclusively determined through a final non-appealable judicial determination (or settlement tantamount thereto) that the Indemnitor is not liable to the Indemnitee under this Section 11.2.3, the Indemnitee shall act reasonably and in accordance with its good faith business judgment with respect thereto, and shall not settle or compromise any such claim or action without the consent of the Indemnitor, which consent shall not be unreasonably withheld. The parties shall render to each other such assistance as may reasonably be requested in order to insure the proper and adequate defense of any such claim or action, including making employees available on a mutually convenient basis to provide additional information and explanation of any relevant materials or to testify at any proceedings relating to such claim or action.

(b) Notwithstanding anything in Section 11.2.3(a) to the contrary, with respect to any Shareholder Retained Litigation, (i) counsel defending such litigation shall be selected by the Shareholder or one of its Affiliates in their sole discretion, and such counsel (x) shall have access to the employees and information of the Company Group in the same manner as has occurred in the defense of such litigation prior to the Share Purchase Closing or the Merger Closing, (y) shall not be deemed or claimed to have any attorney-client relationship with the Parent and its Affiliates other than the Company Group and (z) shall not be disqualified from representing the Shareholder and its Affiliates in any Action or Proceeding with the Parent and its Affiliates by virtue of such defense of the Shareholder Retained Litigation, and Parent and its Affiliates hereby consent to such representation and waive any claim that such counsel may be disqualified from representing Shareholder and its Affiliates in any Action or Proceeding by virtue of such defense of the Shareholder Retained Litigation, (ii) upon the reasonable request of the Parent, the Shareholder will provide the Parent with updates from time to time following the Share Purchase Closing or Merger Closing, as applicable, regarding any material developments in such matter but otherwise shall have no obligation to inform the Parent regarding the status of any such matter, (iii) all decisions regarding the conduct of such litigation, including, without limitation, any settlement decisions or appeal decisions, shall remain solely with the Shareholder and its Affiliates, and the Shareholder and its Affiliates shall have the right to pursue, settle or otherwise resolve any such litigation at any time without advance notice to or the consent of the Parent, on such terms as the Shareholder and its Affiliates deem appropriate in their sole discretion; provided the Shareholder shall have no right to bind the Parent and its Affiliates in the settlement of any such Shareholder Retained Litigation without the consent of the Parent and its Affiliates, which consent shall not be unreasonably withheld, (iv) the Parent and its Affiliates will provide the Shareholder with full access at all times to the Company Group’s properties, books, records and personnel, and documents, as the Shareholder may reasonably request in connection with the Shareholder Retained Litigation, and (v) the Parent and its Affiliates will make the Company Group’s personnel available as witnesses in the Shareholder Retained Litigation or in any other capacity requested by the Shareholder in connection with the Shareholder Retained Litigation.

(c) Within 10 Business Days after an Indemnitee sustains or should have known that it has sustained any Damages not involving a third party claim or action that such Indemnitee reasonably believes may give rise to a claim for indemnification from an

Indemnitor hereunder, and such Indemnitee intends to seek indemnification from such Indemnitor with respect thereto under this Section 11, such Indemnitee shall, if a claim in respect thereof is to be made against an Indemnitor, deliver notice of such claim to the Indemnitor, which notice shall contain the information described in the second sentence of Section 11.2.3(a). Subject to Section 11.1, if the Indemnitee fails to provide such notice within such 10 Business Day period, the Indemnitor will not be obligated to indemnify the Indemnitee with respect to such claim to the extent that the Indemnitor’s ability to defend such claim has been actually prejudiced by such failure of the Indemnitee. If the Indemnitor does not notify the Indemnitee within 30 days following its receipt of such notice that the Indemnitor disputes its liability to the Indemnitee, such claim specified by the Indemnitee in such notice shall be conclusively deemed a liability of the Indemnitor and the Indemnitor shall pay the amount of such claim to the Indemnitee promptly after demand therefor or in the case of any notice in which the amount of the claim (or any portion thereof) is estimated, on such later date when the amount of such claim (or such portion thereof) is finally determined. If the Indemnitor has timely disputed its liability with respect to such claim as provided above, the Indemnitor and the Indemnitee shall proceed in good faith to negotiate a resolution of such dispute and, if not resolved through negotiations, such dispute shall be resolved by litigation in an appropriate court of competent jurisdiction in accordance with Sections 13.14, 13.15 and 13.16.

(d) Without limiting the Shareholder’s rights under other provisions of this Agreement, the Shareholder shall have the right to assume primary control of the resolution of any matter arising under any Environmental Law for which it has an indemnification obligation, including the option to (i) commission any studies or tests reasonably necessary to define or delineate the extent of any contamination or non-compliance with Environmental Laws, (ii) contact Governmental Authorities, make any reports to Governmental Authorities, submit any investigation, remediation or compliance plans to such authorities, negotiate with such authorities and otherwise deal with such authorities, (iii) prepare the work plan for any investigation, remediation or correction of non-compliance with Environmental Laws, and (iv) conduct or direct any such investigation, remediation or correction of noncompliance with Environmental Laws. With respect to claims brought pursuant to Section 11.2.1(i) for breaches of representations or warranties contained in Section 5.17, the Shareholder shall provide the Parent with a right to participate in matters for which the Shareholder has primary control, including, (i) the right to receive and comment on copies of all environmental and engineering studies, work plans, data prepared by the Shareholder or its agents and correspondence or other submissions received from or sent to the Governmental Authority overseeing any investigation, remediation or correction of non-compliance with or liability under any Environmental Laws (and the Shareholder shall address in such documents the reasonable comments of the Parent), and (ii) the right to attend as an observer any meetings with Governmental Authorities overseeing any investigation, remediation or correction of non-compliance with or liability under any Environmental Laws.

(e) With respect to claims brought pursuant to Section 11.2.1(i) for breaches of representations or warranties contained in Section 5.17, the Shareholder shall conduct

any resolution of any matter arising under any Environmental Law for which it has an indemnification obligation and for which it accepts primary control in a manner that will not unreasonably interfere with or unreasonably interrupt the operations or business of the Parent or unreasonably compromise the safety of the property or the business or operations thereon. Promptly upon completion of any phase of investigatory, remedial or corrective actions, the Shareholder shall use commercially reasonable efforts to restore any adversely affected portion of the property to its pre-disturbed condition, such that the Parent can continue its operations in the manner in which such operations were conducted prior to the commencement of the investigatory, remedial or corrective action.

(f) The Shareholder shall have satisfied its indemnification obligations under this Agreement with respect to any matter arising under any Environmental Law if the result meets or exceeds the least stringent standards (including any lesser standards resulting from any site-specific risk assessments and including any deed and land use restrictions and institutional controls to the extent such restrictions reasonably comport with the usage of the property as of the Share Purchase Closing Date or Merger Closing Date, as the case may be, and do not unreasonably interfere with Parent’s operation of property), based on the use of the property on the Share Purchase Closing Date or Merger Closing Date, as the case may be, and applicable Environmental Laws as in effect on the date that any remedial or investigative activities are concluded so long as such standards are or would be acceptable to the Governmental Authority directly overseeing such matter.

(g) Notwithstanding anything in this Agreement to the contrary, the Parent shall not be entitled to indemnification with respect to any claim arising out of or relating to any Environmental Law to the extent that such claims are discovered or identified by environmental sampling or testing conducted by or on behalf of the Parent or its Affiliates, successors, assigns or transferees after the Share Purchase Closing Date or Merger Closing Date, as applicable, unless such sampling or testing (i) is requested by a Governmental Authority or is reasonably necessary to comply with an applicable Environmental Law, (ii) is reasonably necessary to respond to or correct an imminent and substantial threat of risk to human health or the environment or (iii) is reasonably necessary for maintenance or repair performed for a bona fide business purpose.

11.2.4 Mitigation. The parties shall cooperate with each other with respect to resolving any claim or liability with respect to which one party is obligated to indemnify the other party hereunder, including by using commercially reasonable efforts to mitigate or resolve any such claim or liability.

11.2.5 Tax Treatment. Each of the Shareholder and the Parent agrees to treat any indemnification payment made pursuant to this Section 11 as an adjustment to the Foreign Subsidiary Purchase Prices or Merger Consideration, as applicable, for all Tax purposes unless otherwise required by applicable law.

11.2.6 Exclusive Remedy. Subject to Section 13.17 and except with respect to fraud, the indemnities provided for in this Agreement shall be the sole and exclusive remedy of the Parent and Merger Sub and their Affiliates after the Closings against the Shareholder, the

Company and their Affiliates for any inaccuracy of any representation or warranty or any failure or breach of covenant, obligation, condition or agreement to be performed or fulfilled by the Shareholder hereunder or any matters arising under any Environmental Law with respect to any member of the Company Group, including but not limited to any environmental conditions on, at, under or emanating from the facilities owned, leased or operated by any member of the Company Group or elsewhere.

11.2.7 Accounts Receivables Claims. In the event that the Shareholder agrees to or is otherwise required to pay any Damages in connection with a breach of the representation set forth in Section 5.18(v), the Parent shall, or shall cause the applicable member of the Company Group to, promptly upon receipt of and in any event as a condition precedent to such payment, transfer to the Shareholder or its designee all right, title and interest to the uncollected receivables giving rise to such payment. The Parent acknowledges and agrees that the Shareholder may seek collection of such receivables by any reasonable means it deems appropriate, including litigation, and the Parent shall not, and shall cause each member of the Company Group not to, object to or otherwise seek to impair, any such collection.

EXHIBIT G

TRANSITION SERVICES AGREEMENT

This TRANSITION SERVICES AGREEMENT (the “Agreement”), dated as of [___], 2005, is entered into by Columbian Chemicals Company, a Delaware corporation (the “Company”), and Phelps Dodge Corporation, a New York corporation (the “Provider”). The Company and the Provider are referred to herein collectively as “Parties” and each individually as a “Party.”

RECITALS

A. The Company was a wholly-owned subsidiary of the Provider prior to the date of the closing (the “Closing Date”) under the Master Agreement and Plan of Merger, dated as of November 15, 2005, between the Provider, the Company, Columbian Chemicals Acquisition LLC, and Columbian Chemicals Merger Sub, Inc. (the “Purchase Agreement”) (capitalized terms used herein and not defined shall have the meanings set forth in the Purchase Agreement);

B. The Provider or one or more of its Affiliates has historically provided certain human resources, information technology and finance services to the Company Group;

C. For a period of time following the Closing Date, the Company will require the Provider or one or more of its Affiliates to continue providing certain services to the Company Group, during which period the Company Group will undertake such measures as are required to become fully independent of the Provider and its Affiliates; and

D. The Provider has agreed to perform and to cause its Affiliates to perform such services for the Company Group following the Closing Date on the terms and conditions set forth herein.

NOW, THEREFORE, in consideration of the premises and agreements set forth in this Agreement and the Purchase Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties, intending to be legally bound hereby, agree as follows:

ARTICLE I

SERVICES

Section 1.1 Services.

(a) During the Term (as defined below), the Provider shall, or shall cause one or more of its Affiliates to, provide or cause to be provided to the Company Group the human resources services, information technology services and finance related services specified on Exhibit A hereto (the “Services”), in each case for the respective periods set forth opposite such Services on Exhibit A hereto (each a “Service Term”).

(b) The Provider shall perform the Services hereunder in accordance with applicable law. The Provider shall use commercially reasonable efforts to obtain, and the Company agrees

to provide commercially reasonable assistance at the request of the Provider in obtaining, any waivers, permits, consents or sublicenses (collectively, “Consents”) that may be required with respect to agreements with third-party vendors in order to provide any of the Services hereunder; provided that (i) the Company shall pay, or reimburse the Provider for, all costs relating to obtaining such Consents (including, without limitation, any license fees to third party vendors) and (ii) the Provider shall be under no obligation to provide any Service hereunder if it is unable, after using commercially reasonable efforts, to obtain a Consent necessary for the Provider to provide such Service.

Section 1.2 Discontinuation or Extension of Services. The Company may discontinue receiving any or all of the Services by giving the Provider at least thirty (30) days’ prior written notice, which notice shall specify the date as of which any such Services shall be discontinued, provided, that the Company shall not, without the written consent of the Provider, be permitted to discontinue use of one or more Services without discontinuing use of all related Services for which a single Service Fee is provided in Exhibit A. Exhibit A hereto shall be deemed automatically amended to delete such Services as of such date, and this Agreement shall be of no further force and effect with respect to such Services, except as to obligations that accrued prior to the date of discontinuation of such Services and obligations that survive a termination as set forth in Section 6.4; provided that, upon the request of the Provider, the Company shall promptly reimburse the Provider for (i) the Provider’s reasonable out-of-pocket fees and expenses payable to third party service providers, licensors or vendors and (ii) any other reasonable out-of-pocket expenses incurred by the Provider or its Affiliates in providing or discontinuing such Services. The Company may request the extension of a Service Term for any Service upon thirty (30) days’ prior written notice, which notice shall specify the date until which the applicable Services will be provided, provided that no Service Term shall extend beyond the Term of this Agreement.

Section 1.3 Change in Services. The Parties acknowledge the transitional nature of the Services and agree that the Provider may make changes from time to time in the manner of performing the Services, including, without limitation, that the Provider may modify or change the specifications of any Services involving systems and associated computer programs, products, equipment and services from time to time for operational and other reasons. The Provider shall use its commercially reasonable efforts to (i) inform the Company five (5) Business Days in advance of any such modifications and changes, (ii) mitigate any adverse effects on the Company’s operations due to such modifications and changes, and (iii) perform, where reasonably practicable, testing of any such modifications or changes consistent with current practices in advance of making any such modifications or changes. The Provider may in its reasonable discretion suspend the provision of Services (or any part thereof) for reasons of modification or preventative or emergency maintenance. The Provider shall use its commercially reasonable efforts to inform the Company five (5) Business Days in advance of any such suspension and shall cooperate with the Company to mitigate any adverse effects on the Company’s operations due to such suspension. In the event the Company requests the provision of services not set forth in Exhibit A, the parties shall use good faith efforts to accommodate such request and enter into a mutually agreeable amendment to this Agreement to include such requested services, to the extent such requested services are consistent with services customarily provided by the Provider to the Company prior to the execution of this Agreement as part of the Phelps Dodge Program Management Office.

Section 1.4 Standard of Performance. In performing the Services, the Provider shall use at least the same degree of care, skill and diligence with which the Provider performs, or causes to be performed, such Services for itself and its Affiliates, consistent with past practices.

Section 1.5 Independent Contractor. For all purposes hereof, the Provider shall at all times act as an independent contractor and shall have no authority to represent the Company Group in any way or otherwise be deemed an agent, employee, representative, joint venturer or fiduciary of the Company. The Company Group shall not declare or represent to any third party that the Provider shall have any power or authority to negotiate or conclude any agreement, or to make any representation or to give any undertaking, on behalf of the Company Group in any way whatsoever.

ARTICLE II

COMPENSATION

Section 2.1 Costs and Expenses. During the Term, the Company shall pay the fees for each Service received by it during a calendar month as set forth for each Service on Exhibit A hereto, provided, that in the event any such Service is provided by an entity other than the Provider or one of its Affiliates the fee for such Service received during such calendar month shall be the costs paid by the Provider to such entity for such services (the “Service Fees”), and provided further that, in the event the Term is extended pursuant to Section 6.2 hereof, the Company shall pay an additional 10% over the applicable Service Fee for each monthly period of such extension, on a compounded basis. In addition, the Company shall pay certain one-time fees in the amounts set forth in Exhibit A for certain transition services provided to the Company. Provider acknowledges that the Service Fees include all of Provider’s costs and expenses in providing the Services; provided, that Company shall reimburse the Provider for any reasonable out-of-pocket fees and expenses incurred by the Provider or its Affiliates in providing any Services including incremental Consent and license fees paid to third-party licensors and vendors in connection with resources provided to the Company to the extent not otherwise included in the Service Fees (the “Reimbursable Costs”). The Company shall be solely responsible for the payment of all insurance premiums, taxes and associated fees related to insurance coverage placed on its behalf.

Section 2.2 Taxes. The Company shall reimburse the Provider for any sales tax, use tax, value-added tax, goods and services tax or similar tax (but excluding any Tax based upon the net income of the Provider and any Taxes otherwise incorporated into the Services Fees paid by the Company, which shall be paid by the Provider) (“Taxes”) payable with respect to the provision of Services, which shall be separately stated on the relevant invoice. The Provider shall be responsible for paying any such Taxes to the appropriate taxing authority.

ARTICLE III

PAYMENT

Section 3.1 Payment. The Provider shall submit invoices to the Company for the Service Fees, Reimbursable Costs and applicable Taxes, together with appropriate supporting

documentation, monthly in advance, except for (i) certain one-time fees for certain transition services as set forth in Exhibit A to be invoiced by the Provider upon completion of such services, and (ii) all fees for Services charged at an hourly rate, to be invoiced by the Provider monthly in arrears. The Company shall remit payment for Services so invoiced by wire transfer of immediately available funds to the account specified in the invoice within fifteen (15) days after receipt of the invoice. Each invoice shall set forth separately for the period covered by such invoice: (a) the Services rendered by the Provider, (b) the applicable Service Fees and Reimbursable Costs, and (c) copies of invoices for out of pocket expenses for services provided by third parties. If all or any portion of such payment is not made when due, the overdue amount shall bear interest from the date such amount is due until it is paid in full, at an interest rate equal to 18% per annum.

ARTICLE IV

TRANSITION

Section 4.1 System Transition. The Company agrees to use its commercially reasonable efforts to end its use of each of the Services prior to the expiration of the period applicable to such Service on Exhibit A hereto. Without limiting the foregoing, the Provider agrees to use its commercially reasonable efforts to assist the Company to exit from the Provider’s systems, as applicable, provided that the Company pays the Provider for such support at the Provider’s then-current rates or, if the Provider does not have established rates for such support, the Company shall reimburse the Provider for its actual costs incurred in providing such support.

ARTICLE V

INTELLECTUAL PROPERTY

Section 5.1 Title to Intellectual Property. The Parties agree that all intellectual property and data of the Company made available to the Provider in connection with the Services, all derivative works, additions, modifications or enhancements thereof created by the Provider pursuant to this Agreement, and all intellectual property and data developed or produced by the Provider or its Affiliates in connection with this Agreement is and shall remain the sole property of the Company. To the extent that the Provider uses its own or third-party intellectual property in connection with providing the Services, such intellectual property, and any derivative works, additions, modifications or enhancements thereof created during the term hereof shall remain the sole property of Provider or the third party.

ARTICLE VI

TERM AND TERMINATION

Section 6.1 Term. The term of this Agreement shall commence on the Closing Date and end nine (9) months thereafter, unless extended pursuant to Section 6.2 (the original period or the extended period, as applicable, the “Term”). Notwithstanding the foregoing, if all

Services to be provided hereunder are discontinued pursuant to Section 1.2 prior to the end of the Term, the Term shall end on the date the last such Service is discontinued.

Section 6.2 Extension. Absent the written agreement of the Provider to provide any Services after (i) the expiration of the Term or (ii) the date of discontinuation of such services pursuant to Section 1.2, the Provider shall have no further obligation to provide such services after such dates.

In the event that the Provider agrees in writing to such an extension of the Term with respect to all or any portion of such Services, the amount of the fees payable pursuant to Section 2.1 for the provision of any Services to be provided hereunder during such agreed-upon extension shall be increased by 10% for each monthly period of such extension, on a compounded basis, and the Company, in addition to its other obligations under this Agreement, shall be solely responsible for any actual and reasonable additional employee retention costs of the Provider or its Affiliates necessitated by such extension and all costs incurred in obtaining any Consents (including license fees) required for such extended provision of such Services to the Company.

Section 6.3 Termination for Cause. Either party (the “Terminating Party”) may terminate this Agreement with immediate effect by written notice to the other Party (the “Other Party”) on or at any time after the occurrence of any of the following events:

(a) the Other Party is in default of any of its material obligations under this Agreement and (if the breach is capable of remedy) has failed to remedy the breach within thirty (30) days after receipt of a written notice from the Terminating Party with respect thereto;

(b) the Other Party shall commence a voluntary case or other proceeding seeking liquidation, reorganization or other relief with respect to itself or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of it or any substantial part of its property, or shall consent to any such relief or to the appointment of or taking possession by any such official in an involuntary case or other proceeding commenced against it, or shall make a general assignment for the benefit of creditors, or shall fail generally to pay its debts as they become due, or shall take any corporate action to authorize any of the foregoing; and

(c) an involuntary case or other proceeding shall be commenced against the Other Party seeking liquidation, reorganization or other relief with respect to it or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of it or any substantial part of its property, and such involuntary case or other proceeding shall remain undismissed and unstayed for a period of sixty (60) days; or an order for relief shall be entered against the Other Party.

termination or expiration), Section 3.1 (Payment) (to the extent of amounts accrued prior to termination or expiration), Section 5.1 (Intellectual Property), this Section 6.4 (Survival), Article VII (Confidentiality; Systems Security), Article VIII (Indemnity; Limitation of Liability; Certain Waivers), and Article IX (Miscellaneous) shall survive the termination or expiration of this Agreement.

ARTICLE VII

CONFIDENTIALITY; SYSTEMS SECURITY

Section 7.1 Confidentiality.

(a) Except as otherwise provided in this Agreement, (a) the Provider shall, and shall cause its Affiliates (and their respective accountants, counsel, consultants and agents to whom they disclose such information), to keep confidential all information provided by the Company to the Provider in order to perform the Services, and (b) the Company shall, and shall cause its Affiliates (and their respective accountants, counsel, consultants and agents to whom they disclose such information), to keep confidential all information relating to the Provider or its Affiliates that it receives in connection with the performance of the Services that relates to the Provider or its Affiliates, other than any information solely related to the members of the Company Group or their respective assets.

(b) The provisions of this Section 7.1 shall not apply to the disclosure by either Party or their respective Affiliates of any information, documents or materials (i) that are or become publicly available, other than by reason of a breach of this Section 7.1 by such Party or any of its Affiliates, (ii) received from a third party not bound by any confidentiality agreement with the non-disclosing Party, (iii) required by applicable law to be disclosed by such Party, or (iv) necessary to establish such Party’s rights under this Agreement or the Purchase Agreement, provided that in the case of clauses (iii) and (iv), the person intending to make disclosure of confidential information shall promptly notify the Party to whom it is obligated to keep such information confidential and, to the extent practicable, provide such Party a reasonable opportunity to prevent public disclosure of such information.

(c) With regard to confidential information concerning the software of third parties with which the Provider conducts business that is included in or related to the Services, the Company agrees to execute and deliver any other documents or take any actions that are reasonably required by any vendor or licensor of such software in order to access and use such vendor’s software in connection with such vendor’s contracts with the Provider, including abiding by the terms and conditions of any such software license agreements.

Section 7.2 Systems Security. If the Company shall receive access to any of the Provider’s computer facilities, system(s), networks (voice or data) or software (“Systems”) in connection with performance of the Services, the Company shall comply with all system security policies, procedures and requirements that may be provided by the Provider to the Company in writing from time to time (the “Security Regulations”) and shall not tamper with, compromise or circumvent any security or audit measures employed by the Provider. Any employees of the Company that are expected to be given access to the Provider’s Systems may be required to

execute a separate system access agreement. The Company shall ensure that only such Company employees who are specifically authorized to gain access to the Provider’s Systems will gain such access and shall prevent unauthorized destruction, alteration or loss of information contained therein by any Company employee. If at any time the Provider determines that any personnel of the Company has sought to circumvent or has circumvented the Provider’s Security Regulations or that an unauthorized person has accessed or may access the Provider’s Systems or a person has engaged in activities that may lead to the unauthorized access, destruction or alteration or loss of data, information or software, the Provider shall immediately terminate any such person’s access to the Systems and immediately notify the Company. In addition, a material failure to comply with the Provider’s Security Regulations shall be a breach of this Agreement, in which case, the Provider shall notify the Company and both Parties shall work together to rectify said breach. If the Parties do not rectify the breach within thirty (30) days from its occurrence, the Provider shall be entitled to immediately terminate the Services to which the breach relates.

ARTICLE VIII

(b) The Provider shall indemnify and hold harmless and, at the Company’s option, defend the Company, against all Losses to the extent arising out of a claim by a third party arising out of the gross negligence or willful misconduct of the Provider or its Affiliates in their performance of the Services.

(c) The rights of either Party to indemnification under this Section 8.1 shall be limited by the amount of any Losses incurred by a Party and shall be reduced by the net amount such Party recovers (after deducting all attorneys’ fees, expenses and other costs of recovery) from any insurer or other party liable for such Losses. Each Party shall use reasonable efforts to effect any such recovery.

Section 8.2 Limitation of Liability; Certain Waivers.

(a) THE LIABILITY OF THE PROVIDER OR ITS AFFILIATES TO THE COMPANY OR ANY THIRD PARTIES IN CONNECTION WITH THE PERFORMANCE, DELIVERY OR PROVISION OF ANY SERVICES HEREUNDER SHALL BE LIMITED TO THE LOSSES OF THE COMPANY ARISING FROM THE PROVIDER’S OR ITS AFFILIATES’ GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, BUT IN NO EVENT SHALL SUCH LIABILITY OR ANY LIABILITY OF THE PROVIDER HEREUNDER BE GREATER THAN THE TOTAL FEES PAID HEREUNDER. IN NO EVENT SHALL

EITHER PARTY BE LIABLE TO THE OTHER PARTY FOR ANY SPECIAL, INDIRECT, INCIDENTAL, CONSEQUENTIAL, LOST PROFITS, PUNITIVE OR SIMILAR DAMAGES IN ANY ARBITRATION, LAWSUIT, LITIGATION OR PROCEEDING ARISING OUT OF, OR RESULTING FROM, ANY CONTROVERSY OR CLAIM ARISING OUT OF OR RELATING TO THE SERVICES, WHETHER SUCH CLAIM IS BASED ON WARRANTY, CONTRACT, TORT (INCLUDING NEGLIGENCE, GROSS NEGLIGENCE, CONTRIBUTION OR STRICT LIABILITY), OR OTHERWISE, EVEN IF THE PARTY HAS BEEN ADVISED OF THE POSSIBILITY OR LIKELIHOOD OF SUCH DAMAGES, PROVIDED, HOWEVER, THAT THE FOREGOING LIMITATION SHALL NOT APPLY WHERE SUCH DAMAGES ARE RECOVERED FROM AN INDEMNIFIED PARTY BY A THIRD PARTY.

(b) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE IT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THE SERVICES OR THIS AGREEMENT.

(c) EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE EITHER OF THE FOREGOING WAIVERS, (ii) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVERS, (iii) IT MAKES SUCH WAIVERS VOLUNTARILY, AND (iv) IT HAS BEEN INDUCED TO ENTER INTO ANY OF THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 8.2.

Section 8.3 Disclaimer of Warranties. NO WARRANTIES, WHETHER EXPRESS, IMPLIED OR STATUTORY, ARE MADE OR CREATED BETWEEN THE PARTIES, INCLUDING, BUT NOT LIMITED TO, IMPLIED WARRANTIES OF MERCHANTABILITY, NON-INFRINGEMENT AND FITNESS FOR A PARTICULAR PURPOSE.
