(b) Transfer Taxes. The Sellers on the one hand, and the Purchaser, on the other, shall bear in equal portions and pay all sales, use, transfer, recording, gains, stock transfer and other similar taxes and fees (“Transfer Taxes”) if any, arising out of or in connection with the sale of the Purchased Interests pursuant to this Agreement.

(c) Pre-Closing Taxes and Overlap Period Taxes. Sellers shall be responsible for all Pre-Closing Taxes and for Overlap Period Taxes to the extent they relate to events or periods through 12:00 a.m. (California time) on the Closing Date. Tax Returns for Pre-Closing Taxes shall be prepared and filed in accordance with and as set forth in the Partnership Agreement. The Purchaser shall prepare and file Tax Returns for Overlap Period Taxes, and will supply Sellers with a draft of any such returns and a written request for payment of Sellers’ share of such Taxes. The Purchaser preparation of any such Tax Returns shall be subject to Sellers’ approval, which shall not be unreasonably withheld or delayed. Payments of the Sellers’ share must be made to the Purchaser by wire transfer within thirty (30) business days after such request. Liability for Overlap Period Taxes will be allocated between Sellers and the Purchaser on a closing of the books method.

The Sellers shall notify the Purchaser in writing within thirty (30) business days following receipt of the notice from the Purchaser described in this Section 9.1(e) that the Sellers assume control over the contest if so entitled. Each party will bear its own expenses, and the controlling party will keep the other party informed of developments in the case.

Section 10.2 No Other Representations. Notwithstanding anything to the contrary contained in this Agreement, each Party agrees that none of the Sellers nor their respective Affiliates nor their respective Representatives has made or is making any representation or warranty whatsoever, express or implied, written or oral, including any implied representation or warranty as to the condition, merchantability, usage, suitability or fitness for any particular purpose with respect to the Purchased Interests, MPLP or its Assets and Properties, or the Project, except those representations and warranties contained in Article 3 and in any certificate delivered pursuant to Article 7 in particular and without in any way limiting the foregoing, (i) none of the Sellers nor their respective Affiliates nor their respective Representatives makes any representation or warranty regarding any environmental matters and (ii) none of the Sellers nor their respective Affiliates nor their respective Representatives makes any representation or warranty with respect to any financial projections or forecasts relating to MPLP or the Purchased Interests.

ARTICLE XI

INDEMNIFICATION

Section 11.1 Indemnification.

(a) Sellers shall, to the fullest extent permitted by Law, indemnify, defend and hold harmless, on an After Tax Basis, the Purchaser and its Affiliates and the respective officers, directors, employees and shareholders of the foregoing, and their successors and assigns (collectively, the “Purchaser Indemnified Parties”) from, against and with respect to any claim, liability, obligation or Loss, of any kind or character, suffered, incurred or sustained by any Purchaser Indemnified Party or to which it or they become subject, arising out of or relating or attributable to:

(i) any inaccuracy in any representation or breach of warranty of any Seller contained in Article 3 or in any certificate delivered pursuant to Article 7;

(ii) any failure by any of the Sellers to perform or observe, or to have performed or observed, in full, any covenant, agreement or condition to be performed or observed by any of them under this Agreement or under any certificates executed by any Seller in connection with this Agreement.

(b) The Purchaser shall indemnify, to the fullest extent permitted by law, defend and hold harmless, on an After Tax Basis, the Sellers and their Affiliates and the respective partners, officers, directors, employees and shareholders of the foregoing, and their successors and assigns (collectively the “Sellers Indemnified Parties”) from, against and with respect to any claim, liability, obligation, judgment or Loss, of any kind or character, suffered, incurred or sustained by any Sellers Indemnified Party or to which it or they become subject, arising out of or relating or attributable to:

(i) any inaccuracy in any representation or breach of warranty of the Purchaser contained in Article 4 or in any certificate delivered pursuant to Article 8; and

(ii) any failure by the Purchaser to perform or observe, or to have performed or observed, in full, any covenant, agreement or condition to be performed or observed by the Purchaser under this Agreement or under any certificates executed by the Purchaser in connection with this Agreement.

(c) Notwithstanding anything herein to the contrary, no indemnification shall be available to the Purchaser Indemnified Parties under Section 11.1 (a) hereof or to the Sellers Indemnified Parties under Section 11.1(b) hereof:

(i) unless, with respect to any claim, the Loss involves an amount in excess of $100,000; and

(ii) unless the aggregate amount of Losses that would otherwise be subject to indemnification with respect to such claim and all prior claims exceeds $500,000 (such amount, the “Threshold Amount”), in which case the party(ies) entitled to such indemnification shall be entitled to receive all amounts in excess of the Threshold Amount.

(d) Notwithstanding anything herein to the contrary, Sellers shall have no obligation to indemnify any Purchaser Indemnified Party for any Losses pursuant to Section 11.1(a) hereof, and the Purchaser shall have no obligation to indemnify any Seller Indemnified Party for any Losses pursuant to Section 11.1(b) hereof, in each case to the extent such Losses arise from the willful misconduct or gross negligence of the Purchaser or the Sellers, as applicable.

(e) Notwithstanding anything herein to the contrary, the maximum aggregate liability of Sellers to the Purchaser Indemnified Parties under this Agreement shall not exceed an amount equal to $7,000,000; provided that Sellers’ aggregate liability arising out of or relating to breaches by either Seller of its representations in Sections 3.1, 3.2, 3.3, 3.5 or 3.7 may exceed

such amount but shall in no event (together with any other liability pursuant to this clause (e)) exceed the Purchase Price.

(f) None of the Sellers nor their respective Affiliates shall have any liability for any breach by any Seller of this Agreement (or any closing certificate delivered pursuant to Section 7.3) if the Purchaser had knowledge of such breach or the facts giving rise to such breach prior to the Closing (and, without in any way limiting the generality of the foregoing, for purposes of this Section 11.1(f), the documents and their contents and other information disclosed in writing to the Purchaser, its Affiliates or their respective Representatives in the course of the operation of the Project, are deemed known by the Purchaser).

Section 11.2 Method of Asserting Claims. All claims for indemnification by any Indemnified Party under this Section 11.2 will be asserted and resolved as follows:

(a) In the event any claim or demand in respect of which an Indemnified Party believes in good faith it is entitled to indemnity under Section 11.1 is asserted against or sought to be collected from such Indemnified Party by a Person other than the Sellers, the Purchaser or any Affiliate of the Sellers or the Purchaser (a “Third Party Claim”), the Indemnified Party shall deliver a Claim Notice with reasonable promptness to the Indemnifying Party.

(i) If the Indemnifying Party notifies the Indemnified Party within the Dispute Period that the Indemnifying Party desires to defend the Indemnified Party with respect to the Third Party Claim pursuant to this Section 11.2(a), and confirms its responsibility with respect thereto, then the Indemnifying Party will have the right to defend, at the sole cost and expense of the Indemnifying Party, such Third Party Claim by all appropriate proceedings, which proceedings will be diligently prosecuted by the Indemnifying Party, with counsel reasonably acceptable to the Indemnified Party, to a final conclusion or will be settled at the discretion of the Indemnifying Party (subject to the limitations set forth below). From and after the Indemnifying Party’s delivery of the notice referred to in the first sentence of this Section 11.2(a)(i), the Indemnifying Party will have full control of such defense and proceedings, including any settlement thereof; provided that the Indemnifying Party may not settle or compromise any Third Party Claim in any manner that results in any continuing liability or obligation for the Indemnified Party or any admission of liability or wrongdoing by the Indemnified Party, without, in any such case, the prior written consent of the Indemnified Party, which will not be unreasonably withheld. If requested by the Indemnifying Party, the Indemnified Party will, at the sole cost and expense of the Indemnifying Party, cooperate with the Indemnifying Party and its counsel in contesting any Third Party Claim that the Indemnifying Party elects to contest, or, if appropriate and related to the Third Party Claim in question, in making any counterclaim against the Person asserting the Third Party Claim, or any cross-complaint against any Person (other than the Indemnified Party or any of its Affiliates). Notwithstanding the foregoing, the Indemnified Party may take over the control of the defense or settlement of a Third Party Claim at any time if it irrevocably waives its right to indemnity under Section 11.1 with respect to such Third Party Claim.

(ii) Should the Indemnified Party reasonably conclude that there may be defenses available to the Indemnified Party that are different from or additional to those available to the Indemnifying Party, or if the Indemnified Party’s counsel shall have advised the Indemnified Party that there is a conflict of interest that could make it inappropriate under applicable standards of professional conduct to have common counsel, the Indemnified Party shall have the right to request separate counsel from that representing the Indemnifying Party, the expenses of such separate representation to be paid by the Indemnifying Party. If the Indemnifying Party fails to notify the Indemnified Party within the Dispute Period that the Indemnifying Party desires to defend the Third Party Claim pursuant to Section 11.2(a), or if the Indemnifying Party gives such notice but fails to employ counsel reasonably satisfactory to the Indemnified Party or to prosecute diligently the Third Party Claim, then the Indemnified Party will have the right to defend, at the sole cost and expense of the Indemnifying Party, the Third Party Claim by all appropriate proceedings, which proceedings will be diligently prosecuted by the Indemnified Party to a final conclusion or will be settled at the discretion of the Indemnified Party (with the consent of the Indemnifying Party, which consent will not be unreasonably withheld, conditioned or delayed). The Indemnified Party will have full control of any defense and proceedings pursuant to this Section 11.2(a)(ii) (including settlement thereof); provided, that if requested by the Indemnified Party, the Indemnifying Party will, at the sole cost and expense of the Indemnifying Party, cooperate with the Indemnified Party and its counsel in contesting any Third Party Claim which the Indemnified Party is contesting, or, if appropriate and related to the Third Party Claim in question, in making any counterclaim against the Person asserting the Third Party Claim, or any cross-complaint against any Person (other than the Indemnified Party or any of its Affiliates).

(iii) If the Indemnifying Party notifies the Indemnified Party that it does not dispute its responsibility to the Indemnified Party with respect to the Third Party Claim under Section 11.1 or fails to notify the Indemnified Party within the Dispute Period whether the Indemnifying Party disputes its liability to the Indemnified Party with respect to such Third Party Claim, the Losses arising from such Third Party Claim will be conclusively deemed a responsibility of the Indemnifying Party under Section 11.1 and the Indemnifying Party shall pay the amount of such Losses to the Indemnified Party on demand following the final determination thereof. If the Indemnifying Party timely disputes its responsibility with respect to such claim or fails to respond within the Dispute Period, the Indemnifying Party and the Indemnified Party will proceed in good faith to negotiate a resolution of such dispute, and if not resolved through negotiations within the Resolution Period, the Indemnified Party shall be entitled to seek such remedies against the Indemnifying Party as may then be available to it under this Agreement and applicable Laws.

(b) In the event any Indemnified Party should have a claim under Section 11.1 against any Indemnifying Party that does not involve a Third Party Claim, the Indemnified Party shall deliver an Indemnity Notice with reasonable promptness to the Indemnifying Party. If the Indemnifying Party notifies the Indemnified Party that it does not dispute the claim or the amount of Loss therefrom described in such Indemnity Notice, or fails to notify the Indemnified Party within the Dispute Period that it disputes the claim described in the Indemnity Notice, the

Loss in the amount specified in the Indemnity Notice will be conclusively deemed a liability of the Indemnifying Party under Section 11.1 and the Indemnifying Party shall pay the amount of such Loss to the Indemnified Party on demand. If the Indemnifying Party has disputed its liability or the amount of the Loss therefrom with respect to such claim or fails to respond within the Dispute Period, such dispute shall be resolved in accordance with the provisions of Article 12.

Section 11.3 Exclusivity. After the Closing, to the extent permitted by applicable Laws, and except in the case of fraud, gross negligence or willful misconduct, the indemnities set forth in this Article 11 shall be the exclusive remedies of the Purchaser and the Sellers, their respective Affiliates and their respective Representatives due to breach of any representation, warranty, covenant or agreement contained in this Agreement or with respect to any events, occurrences or conditions relating to the Project; provided, however, that the foregoing provision shall not limit or restrict the availability of specific performance or other injunctive or equitable relief (other than rescission) to the extent that specific performance or such other relief would otherwise be available to a Party.

Section 11.4 Notification by the Sellers of Certain Matters. The Sellers may, at the Closing, notify the Purchaser in writing in reasonable detail of any representation or warranty of any of the Sellers that was not true and accurate as of the date of this Agreement or as of the Closing or of any covenant of any of the Sellers that has not been performed and complied with and, if the Purchaser shall in its sole discretion nevertheless elect to close under this Agreement, none of the matters set forth in such certificate shall be deemed to be an inaccuracy in or breach of the specific representations and warranties or covenants of the Sellers so modified for purposes of, and the Purchaser shall not be entitled to be indemnified as to any of such specific representations, warranties and covenants in the form prior to their modification pursuant to, this Article 11.

ARTICLE XII

DISPUTE RESOLUTION

In the event an action, dispute, claim, counterclaim or controversy (“Dispute”) arises between the Parties arising out of or relating to this Agreement, the aggrieved Party or Parties, as applicable, shall promptly notify the other Party or Parties, as applicable, of the Dispute within ten (10) Business Days after the aggrieved Party becomes aware of the basis for such Dispute. If the affected Parties have failed to resolve the Dispute within ten Business Days after delivery of such notice, each affected Party shall, within five (5) Business Days thereafter, nominate a senior officer of its management to meet to attempt to resolve the Dispute. The senior officers shall meet within twenty (20) Business Days after their nomination. If the matter has not been resolved within fourteen (14) days after the meeting of the senior officers, any affected Party may pursue any and all available legal remedies, unless such Parties mutually agree to an alternative dispute resolution procedure.

ARTICLE XIII

TERMINATION

Section 13.1 Termination. This Agreement may be terminated at any time after August 15, 2010, by Sellers or the Purchaser if the Closing shall not have occurred on or before such date and such failure to consummate is not caused by a breach of this Agreement by the terminating party.

Section 13.2 Effect of Termination or Breach.

(a) If this Agreement is validly terminated pursuant to Section 13.1, there will be no liability or obligation on the part of the Sellers or the Purchaser (or any of their Affiliates or any of its or their respective officers, directors, employees, agents or other Representatives) except as provided in Section 13.2(b) and except that the provisions with respect to expenses in Section 14.3 and confidentiality in Section 14.5 will continue to apply following any such termination.

(b) Notwithstanding any other provision in this Agreement to the contrary, if this Agreement is terminated by a party as a result of the willful breach by the non-terminating party, the terminating party may recover such remedies, including damages and fees and expenses of attorneys as may be available at law or equity.
