(c)Acknowledgement Regarding Any Supported QFCs. The following is hereby inserted into the Loan Agreement as a new Section 11.14:

“11.14 Acknowledgement Regarding Any Supported QFCs.

To the extent that the Loan Documents provide support, through a guarantee or otherwise, for Swap Agreements or any other agreement or instrument that is a QFC (such support “QFC Credit Support” and each such QFC a “Supported QFC”), the parties acknowledge and agree as follows with respect to the resolution power of the Federal Deposit Insurance Corporation under the Federal Deposit Insurance Act and Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act (together with the regulations promulgated thereunder, the “U.S. Special Resolution Regimes”) in respect of such Supported QFC and QFC Credit Support (with the provisions below

applicable notwithstanding that the Loan Documents and any Supported QFC may in fact be stated to be governed by the laws of the State of New York and/or of the United States or any other state of the United States): In the event a Covered Entity that is party to a Supported QFC (each, a “Covered Party”) becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer of such Supported QFC and the benefit of such QFC Credit Support (and any interest and obligation in or under such Supported QFC and such QFC Credit Support, and any rights in property securing such Supported QFC or such QFC Credit Support) from such Covered Party will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if the Supported QFC and such QFC Credit Support (and any such interest, obligation and rights in property) were governed by the laws of the United States or a state of the United States. In the event a Covered Party or a BHC Act Affiliate of a Covered Party becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under the Loan Documents that might otherwise apply to such Supported QFC or any QFC Credit Support that may be exercised against such Covered Party are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if the Supported QFC and the Loan Documents were governed by the laws of the United States or a state of the United States. Without limitation of the foregoing, it is understood and agreed that rights and remedies of the parties with respect to a Defaulting Lender shall in no event affect the rights of any Covered Party with respect to a Supported QFC or any QFC Credit Support.”

(d)Secured Obligations. Each Deed of Trust is modified to secure payment and performance of the Loan, as amended to date, in addition to all other “Secured Obligations” as therein defined.

4.Conditions Precedent. Before this Agreement becomes effective and any party becomes obligated under it, all of the following conditions shall have been satisfied at Borrower’s sole cost and expense in a manner acceptable to Administrative Agent and the Lenders, in the exercise of their reasonable judgment:

(b)Administrative Agent shall have received reimbursement, in immediately available funds, of all costs and expenses incurred by Administrative Agent in connection with this Agreement, (if required) including charges for title insurance (including endorsements), recording, filing and escrow charges, fees for appraisal, architectural and engineering review, construction services and environmental services, mortgage taxes, and reasonable legal fees and expenses of Administrative Agent’s counsel.

5.Borrower’s Representations and Warranties. Borrower represents and warrants to Administrative Agent and the Lenders as follows:

(a)Loan Documents. All representations and warranties made and given by Borrower in the Loan Documents are true, accurate and correct in all material respects, subject to any changes in circumstances arising from actions or events occurring after the date of this Agreement that do not otherwise constitute a Default hereunder or under any of the Loan Documents (including, without limitation, execution of new Leases and contracts that are not prohibited by the terms of this Agreement or any other Loan Documents), and (ii) such matters, if any, as have been previously disclosed to Administrative Agent in writing.

(b)No Default. No Default or Unmatured Default has occurred and is continuing.

(c)Borrowing Entity. There have been no changes in the formation

documents of any Borrower since the inception of the Loan that would violate any restrictions set forth in the Loan Documents.

6.Incorporation. This Agreement shall form a part of each Loan Document, and all references to a given Loan Document shall mean that document as hereby modified.

7.No Prejudice; Reservation of Rights. This Agreement shall not prejudice any rights or remedies of Administrative Agent nor any Lender under the Loan Documents. Administrative Agent and the Lenders reserve, without limitation, all rights which it has against any indemnitor, guarantor, or endorser of the Notes.

8.No Impairment. Except as specifically hereby amended, the Loan Documents shall each remain unaffected by this Agreement and all such documents shall remain in full force and effect. Nothing in this Agreement shall impair the lien of any Deed of Trust.

9.Purpose and Effect of Administrative Agent’s and/or Lenders Approval. Administrative Agent and/or any Lender’s approval of any matter in connection with the Loan shall be for the sole purpose of protecting Administrative Agent’s and such Lender’s security and rights. No such approval shall result in a waiver of any default of Borrower. In no event shall Administrative Agent and/or any Lender’s approval be a representation of any kind with regard to the matter being approved.

10.Disclosure to Title Company. Administrative Agent and/or any Lender may, upon no less than three (3) Business Days’ notice to Borrower, disclose to any title insurance company which insures any interest of Administrative Agent under any Deed of Trust (whether as primary insurer, coinsurer or reinsurer) any information, data or material in Administrative Agent’s and/or any Lender’s possession relating to Borrower, the Loan, or the Property.

11.Reversal of Payments. If Administrative Agent receives any payments which are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be paid to a trustee, debtor-in-possession, receiver or any other party under any bankruptcy law, common law, equitable cause or otherwise, then, to such extent, the obligations or part thereof

intended to be satisfied by such payments or proceeds shall be reversed and continue as if such payments or proceeds had not been received by Administrative Agent.

12.Integration. The Loan Documents, including this Agreement: (a) integrate all the terms and conditions mentioned in or incidental to the Loan Documents; (b) supersede all oral negotiations and prior and other writings with respect to their subject matter; and (c) are intended by the parties as the final expression of the agreement with respect to the terms and conditions set forth in those documents and as the complete and exclusive statement of the terms agreed to by the parties.

13.Miscellaneous. This Agreement and any attached consents or exhibits requiring signatures may be executed in counterparts, and all counterparts shall constitute but one and the same document. If any court of competent jurisdiction determines any provision of this Agreement or any of the other Loan Documents to be invalid, illegal or unenforceable, that portion shall be deemed severed from the rest, which shall remain in full force and effect as though the invalid, illegal or unenforceable portion had never been a part of the Loan Documents. This Agreement shall be governed by the laws of the State of California, without regard to the choice of law rules of that State. As used here, the word “include(s)” means “includes(s), without limitation,” and the word “including” means “including, but not limited to.”

14.Limitation on Liability. Notwithstanding the foregoing or anything to the contrary herein, under no circumstances shall Administrative Agent and Lenders have any recourse against, nor shall there be any personal liability to, the members of any Borrower, or to any shareholders, members or partners (direct or indirect, except for the Guarantor under the Guaranty) for any obligations of Borrower hereunder. For purposes of clarification, in no event shall the above language limit, reduce or otherwise affect any Borrower’s liability or obligations under this Agreement, the Loan Documents, Guarantor’s liability or obligations under the Guaranty or Administrative Agent’s and Lenders’ right to exercise any rights or remedies against any collateral securing the Loan.
