(b)    By Purchasers. Subject to the limitations set forth in this Article 6 and Section 7.14, from and after the Closing, each Purchaser agrees to indemnify and hold harmless Seller and Seller’s Affiliates together with their respective directors, officers, managers, employees and agents (each a “Seller Indemnified Party”) from and against any and all Losses that any Seller Indemnified Party incurs by reason of or in connection with any of the following circumstances:

(a)    Minimum Limit on Claims. A party required to provide indemnification under this Article 6 (an “Indemnifying Party”) shall not be liable under this Article 6 to an Indemnified Party for any Claim for breach of any representation or warranty unless and until the aggregate amount of all Claims for which it would, in the absence of this provision, be liable exceeds: (i) in the event that Seller is the Indemnifying Party, the Basket Amount, and (ii) in the event that a Purchaser is the Indemnifying Party, such Purchaser’s pro rata portion (based on its Percentage Portion) of the Basket Amount, and in each such event the Indemnified Party will be liable for the amount of all Claims, including the Basket Amount; provided that the foregoing limitation shall not apply in the case of actual fraud or willful misrepresentation by the Indemnifying Party.

(b)    Maximum Limit on Claims.

(c)    Time Limit for Claims.

(d)    No Double Recovery. For the avoidance of doubt, PSP shall not be entitled to receive indemnification by Seller or PEGI for breach of a representation or warranty by Seller and PEGI (solely with respect to the representations and warranties of PEGI in Appendix B-6) in respect of all or any portion of any Loss more than once and if the same fact, matter, event or circumstance gives rise to claims against Seller and PEGI by PSP for breach of a representation or warranty, PSP shall only be entitled to recover once the amount of the same Losses arising in connection with such fact, matter, event or circumstance and shall not be entitled to double recovery from each of Seller and PEGI.

6.3    Reimbursements; Refunds.

(a)    Right of Reimbursement. The amount of Losses payable under Section 6.1 by an Indemnifying Party shall be net of any amounts recovered by the Indemnified Party under applicable insurance policies or from any other Person responsible therefor. If the Indemnified Party receives any amounts under applicable insurance policies, or from any other Person responsible for any Losses subsequent to an indemnification payment by the Indemnifying Party and such amounts would result in a duplicative recovery, then such Indemnified Party shall promptly reimburse the Indemnifying Party for any payment made or expense incurred by such Indemnifying Party in connection with providing such indemnification payment up to the amount received by the

Indemnified Party, net of any expenses incurred by such Indemnified Party in collecting such amount.

(b)    Other Refund Obligations. In addition to the obligations set forth in Section 6.3(a), the applicable Indemnified Party shall be obligated to reimburse or refund to the Indemnifying Party for payments made by it to such Indemnified Party under this Article 6 as set forth in Part VI of Appendix B.

6.4    Right to Control Proceedings for Third Party Claims.

(a)    If a third party shall notify any party with respect to any matter that may give rise to a Claim (a “Third Party Claim”), the Indemnified Party must give notice to the Indemnifying Party of the Third Party Claim (a “Third Party Claim Notice”) within twenty (20) Business Days after it becomes aware of the existence of the Third Party Claim and that it may constitute a Third Party Claim. The Indemnified Party’s failure to give a Third Party Claim Notice in compliance with this Section 6.4(a) of any Third Party Claim which may give rise to a right of indemnification hereunder shall not relieve the Indemnifying Party of any liability which it may have to the Indemnified Party unless, and solely to the extent that, the failure to give such notice materially and adversely prejudiced the Indemnifying Party.

(b)    The Indemnifying Party shall have the right to participate in, or by giving written notice to the Indemnified Party, to assume control of the defense of any Third Party Claim with the Indemnifying Party’s own counsel, in each case at the Indemnifying Party’s own cost and expense (provided that prior to assuming control of such defense, the Indemnifying Party must acknowledge its indemnity obligations under this Article 6), and the Indemnified Party shall cooperate in good faith in such defense. The Indemnified Party shall have the right, at its own cost and expense, to participate in the defense of any Third Party Claim with separate counsel selected by it, subject to the Indemnifying Party’s right to control the defense thereof; provided that in such event the Indemnifying Party shall pay the fees and expenses of such separate counsel (i) incurred by the Indemnified Party prior to the date the Indemnifying Party assumes control of the defense of the Third Party Claim, (ii) if such Third Party Claim would reasonably be expected to be materially detrimental to the business, reputation or future prospects of any Indemnified Party or (iii) if representation of both the Indemnifying Party and the Indemnified Party by the same counsel would create a conflict of interest. If the Indemnifying Party (i) fails to promptly notify the Indemnified Party in writing of its election to defend or fails to acknowledge its indemnity obligations under this Article 6 as provided in this Agreement, (ii) elects not to defend (or compromise at its sole cost and expense) such Third Party Claim, (iii) has elected to defend such Third Party Claim but fails to promptly and diligently pursue the defense such Third Party Claim, (iv) otherwise breaches any of its obligations under this Article 6 or (v) as set forth on Schedule 6.4(b) hereto, or if the Third Party Claim is reasonably expected by the Indemnified Party to result in a payment obligation on the Indemnified Party in an amount that exceeds the maximum indemnification then available to the Indemnified Party pursuant to this Article 6, then the Indemnifying Party shall not be entitled to assume or maintain control of the defense of such Third Party Claim and the Indemnified Party may (by written notice to the Indemnifying Party) assume control of such defense (in which case the Indemnifying Party shall pay the fees and expenses of counsel retained by the Indemnified

Party) and/or compromise such Third Party Claim and seek indemnification for any and all Losses based upon, arising from or relating to such Third Party Claim. The parties shall cooperate with each other in all reasonable respects in connection with the defense of any Third Party Claim.

(c)    Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not enter into any 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 6.4(c). If a firm offer is made to settle a Third Party Claim that (i) does not (A) result in any liability or create any financial or other obligation on the part of the Indemnified Party and (B) result in the loss of any right or benefit on the part of any Indemnified Party, (ii) does not impose injunctive or other equitable relief against any Indemnified Party, and (iii) 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 firm offer, then 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 twenty (20) 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 within such twenty (20) day period and also fails to assume defense of such Third Party Claim, the 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 6.4(b), it may settle the Third Party Claim; provided that if the settlement is made without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld or delayed), the Indemnifying Party shall have no indemnity obligation pursuant to this Article 6 with respect to such Third Party Claim.

6.5    Mitigation; Treatment of Indemnification.

(a)    The Indemnified Party shall use commercially reasonable efforts to mitigate all Losses relating to a Claim for which indemnification is sought under this Article 6.

(b)    All indemnification payments under this Article 6 shall be deemed adjustments to the Aggregate Purchase Price.

6.6    Exclusive Remedy. Seller and Purchasers acknowledge and agree that, should the Closing occur, and excluding liability for actual fraud or willful misrepresentation, the foregoing indemnification provisions of this Article 6 and the provisions of Section 7.15 shall be the sole and exclusive remedy of Seller and Purchasers with respect to any misrepresentation, breach of warranty, covenant or other agreement (other than any Purchase Price Adjustment set forth in Part I of Appendix B) or other claim arising out of this Agreement or the transactions contemplated hereby. Without limiting the generality of the foregoing, effective as of the Closing each of the Purchasers and Seller covenants to the other party that in respect of any matters under or contemplated in this Agreement, it will not make any Claim whatsoever against any Affiliate of the other party or the directors, officers, managers, shareholders, member, controlling persons, employees and agents of any of the foregoing, in each case in their capacities as such, and its rights in respect of any such

Claim for breach of any provision of this Agreement are limited solely to such rights as it may have against Seller or Purchasers, as the case may be, under this Agreement.

6.7    Purchaser Indemnification Decisions. Each Purchaser may bring a Claim for indemnification pursuant to this Article 6. If both Purchasers initiate substantially the same Claim (a “Joint Claim”), PEGI shall have the right to assume control of the prosecution of such Joint Claim but may not enter into any settlement with the Indemnifying Party that purports to bind PSP with respect to such Joint Claim without the prior written consent of PSP (such consent not to be unreasonably withheld, conditioned or delayed). If PEGI has elected to prosecute such Joint Claim but fails to promptly and diligently pursue the same, then PSP may (by written notice to PEGI) assume control of the prosecution of such Joint Claim but may not enter into any settlement with the Indemnifying Party with respect to such Joint Claim that purports to bind PEGI without the prior written consent of PEGI (such consent not to be unreasonably withheld, conditioned or delayed). Neither Purchaser may enter into any settlement with respect to any Joint Claim solely for itself (i.e., any settlement that does not purport to bind the other Purchaser) without first notifying the other Purchaser and giving the other Purchaser a reasonable opportunity to participate in such settlement. The expenses of the prosecution of any Joint Claim shall be borne by both Purchasers pro rata in accordance with their Percentage Portion.

7.1    Entire Agreement. This Agreement and the Schedules and Appendices hereto, each of which is hereby incorporated herein, set forth all of the promises, covenants, agreements, conditions, undertakings, representations and warranties between the parties hereto with respect to the subject matter hereof and supersede all prior and contemporaneous agreements and understandings, inducements or conditions, express or implied, oral or written.
