Sellers shall have a period of 30 days after delivery of the PP Adjustment Documents to review (and cause Sellers’ auditors to review) such documents and make any objections they may have in writing to Buyers. For purposes of Sellers’ evaluation of the PP Adjustment Documents, Buyers shall, and shall cause the Companies to, make available or provide reasonable access to Sellers and their respective Representatives, upon reasonable advance notice and during normal business hours, all information, books, records, data and working papers created or used in connection with the preparation of the PP Adjustment Documents; and

10

shall permit reasonable access, upon reasonable advance notice and during normal business hours, to the facilities and personnel of the Companies as may be reasonably requested by Sellers and their respective Representatives to analyze the PP Adjustment Documents. If Sellers deliver written objections to Buyers within such 30-day period, then Buyers and Sellers shall attempt to resolve the matter or matters in dispute. If no written objections are made by Sellers within such 30-day period, then such PP Adjustment Documents and the calculation of the Final Closing Purchase Price shall be final and binding on the Parties. If disputes with respect to such PP Adjustment Documents cannot be resolved by Buyers and Sellers within 30 days after timely delivery of any objections thereto, then the specific matters in dispute (but no others) shall be submitted to Deloitte US or such other internationally recognized independent accounting firm as may be approved by Sellers and Buyers (the “ Independent Auditor ”), which firm shall render its opinion as to such specific matters.

Judgment may be entered upon the determination of the Independent Auditor in any court having jurisdiction over the Party against which such determination is to be enforced.

Such notice by the Indemnified Party shall describe the Third-Party Claim in reasonable detail, shall include copies of all material written evidence thereof and shall indicate the estimated amount, if reasonably practicable, of the Loss that has been or may be sustained by the Indemnified Party. Within 30 days after receipt of any such notice, or, if shorter, the deadline by which a response is required to respond to the related Third-Party Claim under Law, the Indemnifying Party must notify the Indemnified Party in writing (i) whether the Indemnifying Party disputes its potential liability to the Indemnified Party under this Article VI with respect to that Third-Party Claim and (ii) if the Indemnifying Party does not dispute its potential liability to the Indemnified Party with respect to that Third-Party Claim and whether the Indemnifying Party elects to assume the defense of any Third-Party Claim at the Indemnifying Party’s expense and by the Indemnifying Party’s own counsel. The Indemnifying Party shall have the right to participate in the defense of any Third-Party Claim at the Indemnifying Party’s expense, and the Indemnified Party shall provide reasonable cooperation in good faith in such defense. In the event that the Indemnifying Party assumes the defense of any Third-Party Claim, subject to Section  6.5(b) , it shall have the right to take such action as it deems necessary to avoid, dispute, defend, appeal or make counterclaims pertaining to any such Third-Party Claim in the name and on behalf of the Indemnified Party. The Indemnified Party shall have the right, at its own cost and expense, to participate in the defense of any Third-Party Claim with counsel selected by it subject, if applicable, to the Indemnifying Party’s right to control the defense thereof. If the Indemnifying Party elects not to defend such Third-Party Claim or fails to promptly notify the Indemnified Party in writing of its election to defend as provided in this Agreement, the Indemnified Party may, subject to Section  6.5(b) , pay, compromise or defend against such Third-Party Claim and seek indemnification for any and all Losses based upon, arising from or relating to such Third-Party Claim. Sellers and Buyers shall cooperate with each other in all reasonable respects in connection with the defense of any Third-Party Claim, including making available (subject to the provisions of Section  7.6 ) records relating to such Third-Party Claim and furnishing, without expense (other than reimbursement of actual out-of-pocket expenses) to the defending party, management employees of the non-defending party as may be reasonably necessary for the preparation of the defense of such Third-Party Claim.

(b) Settlement of Third-Party Claims . Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not agree to settlement of any Third-Party Claim without the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld or delayed), except as provided in this Section  6.5(b) . If a firm offer is made to settle a Third-Party Claim without leading to Liability or the creation of a financial or other obligation on the part of the Indemnified Party and without admission of fault, culpability or failure to act by or on behalf of any Indemnified Party or any Affiliate of any Indemnified Party and provides, in customary form, for the unconditional release of each Indemnified Party from all liabilities and obligations in connection with such Third-Party Claim and the Indemnifying Party desires to accept and agree to such offer, the Indemnifying Party shall give written notice to that effect to the Indemnified Party. If the Indemnified Party fails to consent to such firm offer within 10 days after its receipt of such notice, the Indemnified Party may continue to contest or defend such Third-Party Claim and in such event, the maximum Liability of the Indemnifying Party as to such Third-Party Claim shall not exceed the amount of such settlement offer. If the Indemnified Party fails to consent to such firm offer and also fails to assume defense of such Third-Party Claim, the

33

Indemnifying Party may settle the Third-Party Claim upon the terms set forth in such firm offer to settle such Third-Party Claim. If the Indemnified Party has assumed the defense pursuant to Section  6.5(a) , it shall not agree to any settlement without the written consent of the Indemnifying Party (which consent shall not be unreasonably withheld or delayed).

(c) Direct Claims . Any claim by an Indemnified Party on account of a Loss which does not result from a Third-Party Claim (a “ Direct Claim ”) shall be asserted by the Indemnified Party giving the Indemnifying Party prompt written notice thereof. Such notice by the Indemnified Party shall describe the Direct Claim in reasonable detail, shall include copies of all material written evidence thereof and shall indicate the estimated amount, if reasonably practicable, of the Loss that has been or may be sustained by the Indemnified Party. The Indemnifying Party shall have 30 days after its receipt of such notice to respond in writing to such Direct Claim. During such 30 day period, the Indemnified Party shall allow the Indemnifying Party and its professional advisors to investigate the matter or circumstance alleged to give rise to the Direct Claim, and whether and to what extent any amount is payable in respect of the Direct Claim and the Indemnified Party shall assist the Indemnifying Party’s investigation by giving such information and assistance (including access to the Companies’ premises and personnel and the right to examine and copy any accounts, documents or records) as the Indemnifying Party or any of its professional advisors may reasonably request. If the Indemnifying Party does not so respond within such 30-day period, such Direct Claim specified in such notice shall be deemed a Liability of the Indemnifying Party. If the Indemnifying Party timely disputes such Direct Claim, as provided above, such dispute shall be resolved by litigation in an appropriate court of competent jurisdiction on the terms and subject to the provisions of this Agreement.

(d) Tax Treatment of Indemnification Payments . All indemnification payments made under this Agreement shall be treated by the Parties as an adjustment to the Purchase Price for Tax purposes, unless otherwise required by Law.

6.6 Exclusive Remedies . The Parties acknowledge and agree that, except as provided in Section  7.7(b) , their sole and exclusive remedy with respect to any and all claims (other than claims arising from intentional fraud or willful misconduct on the part of a party hereto in connection with the transactions contemplated by this Agreement) for any breach of any representation, warranty, covenant, agreement or obligation set forth herein or otherwise relating to the subject matter of this Agreement, shall be pursuant to the indemnification provisions set forth in this Article VI . Nothing in this Section  6.6 shall limit any Person’s right to seek any remedy on account of intentional fraud or willful misconduct by any Person.

It is specifically agreed that the time periods specified in this Section  7.7 will be computed by excluding from that computation any time during which the Sellers are in violation of any provision of this Section  7.7 .

(b) in the case of other Taxes, deemed to be the amount of such Taxes for the entire period multiplied by a fraction, the numerator of which is the number of days in the period ending on the Closing Date and the denominator of which is the number of days in the entire period.

8.4 Contests . Buyers agree to give written notice to Sellers of the receipt of any written notice by the Companies, Buyers or any of Buyers’ Affiliates which involves the assertion of any claim, or the commencement of any Action, in respect of which an indemnity may be sought by Buyers pursuant to this Article VIII (a “ Tax Claim ”); provided, that failure to comply with this provision shall not affect Buyers’ right to indemnification hereunder. No Tax Claim shall be subject to the limitation on indemnity set forth in Section  6.4(a) or Section  6.4(b) . Buyers shall control the contest or resolution of any Tax Claim; provided, however, that Buyers shall obtain the prior written consent of Sellers (which consent

42

shall not be unreasonably withheld or delayed) before entering into any settlement of a Tax Claim or ceasing to defend such Tax Claim; and, provided further, that Sellers shall be entitled to participate in the defense of such Tax Claim and to employ counsel of its choice for such purpose, the fees and expenses of which counsel shall be borne solely by Sellers.

8.5 Cooperation . Sellers and Buyers shall provide each other with such cooperation and information as either of them reasonably may request of the other in filing any Tax Return pursuant to this Article VIII or in connection with any audit or other proceeding in respect of Taxes of the Companies. Such cooperation and information shall include providing copies of relevant Tax Returns or portions thereof, together with accompanying schedules, related work papers and documents relating to rulings or other determinations by tax authorities. Each of Sellers and Buyers shall retain all Tax Returns, schedules and work papers, records and other documents in its possession relating to Tax matters of the Companies for any taxable period beginning before the Closing Date until the expiration of the statute of limitations of the taxable periods to which such Tax Returns and other documents relate, without regard to extensions except to the extent notified by the other Party in writing of such extensions for the respective Tax periods. Prior to transferring, destroying or discarding any Tax Returns, schedules and work papers, records and other documents in its possession relating to Tax matters of the Companies for any taxable period beginning before the Closing Date, Sellers or Buyers (as the case may be) shall provide the other Party with reasonable written notice and offer the other Party the opportunity to take custody of such materials.

8.6 Purchase Price Allocation . No later than 60 days after the Closing Date, Buyers shall prepare and deliver to Sellers for their review and comment a statement setting forth allocation of the sum of the relevant portion of the Purchase Price (and Liabilities or any other items treated as consideration for U.S. federal income tax purposes) of the Companies among the relevant Company assets, which allocation shall be made in accordance with Section 1060 of the Code and all applicable U.S. Treasury regulations (the “ Allocation ”). Sellers shall notify Buyers in writing within 30 days after receipt of the Allocation of any reasonable objections Sellers may have with the Allocation, in which case Buyers and Sellers shall negotiate in good faith to reach agreement on the Allocation. The Allocation finally determined pursuant to agreement of the Parties, if any, shall be used by the Parties (and, as relevant, their Affiliates) for all purposes, including preparation and filing of IRS Form 8594, and no Party or its Affiliates shall take or assert any position inconsistent with the final Allocation except to the extent required by Law or to reflect further adjustments to the Purchase Price.
