The Loan is being made pursuant to the Loan Agreement, and is evidenced and/or secured by the Loan Documents, which include, but are not limited to, the Loan Agreement, the Note, the Pledge Agreement and this Agreement.

W I T N E S S E T H:

WHEREAS, Lender has agreed to make the Loan to Borrower;

WHEREAS, the Loan is evidenced by the Note and is secured by the Collateral;

WHEREAS, as a condition to making the Loan to Borrower, Lender has required that Guarantor guarantee payment to, and be additionally directly and primarily liable on a fully recourse basis to Lender for all of those items and circumstances for which Borrower is personally liable and for which Lender has recourse against Borrower under the terms of the Loan Documents; and

WHEREAS, Guarantor is the owner of substantial indirect interests in Borrower, the making of the Loan to Borrower is of substantial benefit to Guarantor and, therefore, Guarantor desires to guarantee payment to, and be additionally directly and primarily liable on a fully recourse basis to, Lender for all of those items and circumstances for which Borrower is personally liable and for which Lender has recourse against Borrower under the terms of the Loan Documents.

NOW, THEREFORE, to induce Lender to make the Loan to Borrower, Guarantor hereby covenants and agrees for the benefit of Lender, as follows:

1. Guaranty. Guarantor hereby irrevocably, absolutely and unconditionally guarantees payment and performance to Lender of the Guaranteed Obligations (as defined below).

As used herein, the term “Guaranteed Obligations” means the obligations or liabilities of Borrower to Lender for the following:

(a) all amounts for which Article XII of the Loan Agreement expressly provides that Borrower shall be liable.

This is a guaranty of payment and performance and not of collection. The liability of Guarantor under this Agreement shall be direct and immediate and not conditional or contingent upon the pursuit of any remedies against any Individual Borrower or any other person (including, without limitation, other guarantors, if any), nor against the collateral for the Loan. Guarantor waives any right to require that an action be brought against any Individual Borrower or any other person or to require that resort be had to any collateral for the Loan or to any balance of any deposit account or credit on the books of Lender in favor of any Individual Borrower or any other person. In the event, on account of the Bankruptcy Reform Act of 1978, as amended, or any other debtor relief law (whether statutory, common law, case law or otherwise) of any jurisdiction whatsoever, now or hereafter in effect, which may be or become applicable, any Individual Borrower shall be relieved of or fail to incur any debt, obligation or liability which is guaranteed herein, Guarantor shall nevertheless be fully liable therefor. Upon the occurrence and during the continuance of any condition or event as to which Guarantor is liable hereunder, Lender shall have the right to enforce its rights, powers and remedies (including, without limitation and if applicable, foreclosure of all or any portion of the collateral for the Loan) under the other Loan Documents or hereunder, in any order, and all rights, powers and remedies available to Lender in such event shall be non-exclusive and cumulative of all other rights, powers and remedies provided thereunder or hereunder or by law or in equity. If the Guaranteed Obligations are partially paid or discharged by reason of the exercise of any of the remedies available to Lender, this Agreement shall nevertheless remain in full force and effect, and Guarantor shall remain liable for all remaining Guaranteed Obligations, even though any rights which Guarantor may have against any Individual Borrower may be destroyed or diminished by the exercise of any such remedy. All sums payable under this Agreement shall be paid in lawful money of the United States of America that at the time of payment is legal tender for the payment of public and private debts.

2. Reinstatement of Obligations.

(a) If at any time all or any part of any payment made by Guarantor or received by Lender from Guarantor under or with respect to this Agreement is or must be rescinded or returned for any reason whatsoever (including, but not limited to, the insolvency, bankruptcy or reorganization of Guarantor or any Borrower), then the obligations of Guarantor hereunder shall, to the extent of the payment rescinded or returned, be deemed to have continued in existence, notwithstanding such previous payment made by Guarantor, or receipt of payment by Lender, and the obligations of Guarantor hereunder shall continue to be effective or be reinstated, as the case may be, as to such payment, all as though such previous payment by Guarantor had never been made.

(b) In the event any payment by Borrower or any other Person to Lender is held to constitute a preference, fraudulent transfer or other voidable payment under any bankruptcy, insolvency or similar law, or if for any other reason Lender is required to refund such payment or pay the amount thereof to any other party, such payment by Borrower or any other party to Lender shall not constitute a release of Guarantor from any liability hereunder and this Agreement shall continue to be effective or shall be reinstated (notwithstanding any prior release, surrender or discharge by Lender of this Agreement or of Guarantor), as the case may be, with respect to, and this Agreement shall apply to, any and all amounts so refunded by Lender or paid by Lender to another Person (which amounts shall constitute part of the Guaranteed Obligations of Borrower), and any interest paid by Lender and any attorneys’ reasonable fees, costs and expenses paid or

2

actually incurred by Lender in connection with any such event. If acceleration of the time for payment of any amount payable by Borrower under any Loan Document is stayed or delayed by any law or tribunal, any amounts due and payable hereunder shall nonetheless be payable by Guarantor on demand by Lender.

3. Waivers by Guarantor. Guarantor hereby expressly waives and agrees not to assert or take advantage of and hereby agrees that neither Lender’s rights or remedies nor Guarantor’s obligations under the terms of this Agreement shall be released, diminished, impaired, reduced or affected by any one or more of the following events, actions, facts, or circumstances, and the liability of Guarantor under this Agreement shall be absolute and unconditional irrespective of (and Guarantor hereby waives any rights or protections related to):

(i) any right to require Lender to proceed against any Individual Borrower or any other person or to proceed against or exhaust any security held by Lender at any time or to pursue any other remedy in Lender’s power or under any other agreement before proceeding against Guarantor hereunder;

(ii) the defense of the statute of limitations in any action hereunder;

(xiv) any modifications of the Loan Documents or any obligation of any Individual Borrower relating to the Loan by operation of law or by action of any court, whether pursuant to the Bankruptcy Reform Act of 1978, as amended, or any other debtor relief law (whether statutory, common law, case law or otherwise) of any jurisdiction whatsoever, now or hereafter in effect, or otherwise;

(a) Fully Recourse. Subject to Section 8, all of the terms and provisions of this Agreement are recourse obligations of Guarantor and not restricted by any limitation on personal liability.

6

(b) Unsecured Obligations. Guarantor hereby acknowledges that Lender is not willing to accept the consequences of the inclusion of the Guaranteed Obligations set forth herein among the Obligations secured by the Pledge Agreement and the other Loan Documents and that Lender would not make the Loan but for the unsecured personal liability (subject to Section 8 below) undertaken by Guarantor herein. Anything to the contrary herein or elsewhere notwithstanding, this Agreement shall not be secured by the Pledge Agreement or by any of the other Loan Documents or by any of the Collateral or other collateral or by any security of any nature which secures the Loan or which secures any of the Obligations which are secured by the Loan Documents. Without limitation, this provision has priority over any provision of this Agreement or of any of the other Loan Documents which states (directly or indirectly) or implies that this Agreement is so secured.

(c) Survival. This Agreement shall be deemed to be continuing in nature and shall remain in full force and effect and shall survive the exercise of any remedy by Lender under the Pledge Agreement or any of the other Loan Documents, including, without limitation, any foreclosure or assignment in lieu thereof, even if, as a part of such remedy, the Loan is paid or satisfied in full; provided that, subject to the provisions of Section 2 hereof, this Agreement shall terminate at such time as the Obligations have been indefeasibly paid in full in cash and satisfied in accordance with the Loan Documents, and there has expired the maximum possible period thereafter during which any payment made by Borrower or others to Lender with respect to the Obligations could be deemed a preference under the Bankruptcy Code.

(d) No Subrogation; No Recourse Against Lender. Notwithstanding the satisfaction by Guarantor of any liability hereunder, Guarantor shall not have any right of subrogation, contribution, reimbursement or indemnity whatsoever or any right of recourse to or with respect to the assets or property of any Individual Borrower or to any collateral for the Loan until such time as the Obligations have been indefeasibly paid in full in cash and satisfied in accordance with the Loan Documents, and there has expired the maximum possible period thereafter during which any payment made by Borrower or others to Lender with respect to the Obligations could be deemed a preference under the Bankruptcy Code. In connection with the foregoing, Guarantor expressly waives any and all rights of subrogation to Lender against Borrower (and against each and any Individual Borrower), and Guarantor hereby waives any rights to enforce any remedy which Lender may have against any Individual Borrower and any right to participate in any collateral for the Loan until such time as the Obligations have been indefeasibly paid in full in cash and satisfied in accordance with the Loan Documents, and there has expired the maximum possible period thereafter during which any payment made by Borrower or others to Lender with respect to the Obligations could be deemed a preference under the Bankruptcy Code. In addition to and without in any way limiting the foregoing, Guarantor hereby subordinates any and all indebtedness of Borrower (and of each and any Individual Borrower) now or hereafter owed to Guarantor to all indebtedness of Borrower (and of each and every Individual Borrower) to Lender, and agrees with Lender that Guarantor shall not demand or accept any payment of principal or interest from any Individual Borrower, shall not claim any offset or other reduction of Guarantor’s obligations hereunder because of any such indebtedness and shall not take any action to obtain any of the collateral from the Loan until such time as the Obligations have been indefeasibly paid in full in cash and satisfied in accordance with the Loan Documents, and there has expired the maximum possible period thereafter during which any payment made by Borrower or others to Lender with respect to the Obligations could be deemed a preference under the Bankruptcy Code. Further, Guarantor shall not have any right of recourse against Lender by reason of any action Lender may take or omit to take under the provisions of this Agreement or under the provisions of any of the Loan Documents.

7

(e) Reservation of Rights. Nothing contained in this Agreement shall prevent or in any way diminish or interfere with any rights or remedies, including, without limitation, the right to contribution, which Lender may have against Borrower, Guarantor or any other party under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (codified at Title 42 U.S.C. §9601 et seq.), as it may be amended from time to time, or any other applicable federal, state or local laws, all such rights being hereby expressly reserved.

(f) Financial Statements. Guarantor hereby agrees, as a material inducement to Lender to make the Loan to Borrower, to furnish to Lender current and dated financial statements in accordance with Article V of the Loan Agreement.

(g) Rights Cumulative; Payments. Lender’s rights under this Agreement shall be in addition to all rights of Lender under the Loan Agreement, the Note, the Pledge Agreement and the other Loan Documents. FURTHER, PAYMENTS MADE BY GUARANTOR UNDER THIS AGREEMENT SHALL NOT REDUCE IN ANY RESPECT BORROWER’S OBLIGATIONS AND LIABILITIES UNDER THE LOAN AGREEMENT, THE NOTE, THE PLEDGE AGREEMENT AND THE OTHER LOAN DOCUMENTS.

(h) No Limitation on Liability. Guarantor hereby consents and agrees that Lender may at any time and from time to time without further consent from Guarantor do any of the following events, and the liability of Guarantor under this Agreement shall be unconditional and absolute and shall in no way be impaired or limited by any of the following events, whether occurring with or without notice to Guarantor or with or without consideration: (i) any extensions of time for performance required by any of the Loan Documents or extension or renewal of the Note; (ii) any sale, assignment or foreclosure of any Note, any of the Pledge Agreement or any of the other Loan Documents or any sale or transfer of any of the Collateral; (iii) any change in the composition of any Individual Borrower, including, without limitation, the withdrawal or removal of Guarantor from any current or future position of ownership, management or control of any Individual Borrower; (iv) the accuracy or inaccuracy of the representations and warranties made by Guarantor herein or by Borrower (or any Individual Borrower) in any of the Loan Documents; (v) the release of any Individual Borrower or of any other person or entity from performance or observance of any of the agreements, covenants, terms or conditions contained in any of the Loan Documents by operation of law, Lender’s voluntary act or otherwise; (vi) the release or substitution in whole or in part of any security for the Loan; (vii) Lender’s failure to file any financing statement (or Lender’s improper filing thereof) or to otherwise perfect, protect, secure or insure any lien or security interest given as security for the Loan; (viii) the modification of the terms of any one or more of the Loan Documents; or (ix) the taking or failure to take any action of any type whatsoever. No such action which Lender shall take or fail to take in connection with the Loan Documents or any collateral for the Loan, nor any course of dealing with any Individual Borrower or any other person, shall limit, impair or release Guarantor’s obligations hereunder, affect this Agreement in any way or afford Guarantor any recourse against Lender. Nothing contained in this Section shall be construed to require Lender to take or refrain from taking any action referred to herein.

(i) Entire Agreement; Amendment; Severability. This Agreement contains the entire agreement between the parties respecting the matters herein set forth and supersedes all prior agreements, whether written or oral, between the parties respecting such matters. No condition or conditions precedent to the effectiveness of this Agreement exist. This Agreement shall be

effective upon execution by Guarantor and delivery to Lender. This Agreement may not be modified, amended or superseded except in a writing signed by Lender and Guarantor referencing this Agreement by its date and specifically identifying the portions hereof that are to be modified, amended or superseded. A determination that any provision of this Agreement is unenforceable or invalid shall not affect the enforceability or validity of any other provision, and any determination that the application of any provision of this Agreement to any person or circumstance is illegal or unenforceable shall not affect the enforceability or validity of such provision as it may apply to any other persons or circumstances.

(a) Lender may, without notice to, or consent of, Guarantor, sell, assign or transfer to or participate with any entity or entities all or any part of the indebtedness secured hereby in accordance with the Loan Agreement, and each such entity or entities shall have the right to enforce the provisions of this Agreement and any of the other Loan Documents as fully as Lender, provided that Lender shall continue to have the unimpaired right to enforce the provisions of this Agreement and any of the other Loan Documents as to so much of the indebtedness secured hereby that Lender has not sold, assigned or transferred. In connection with the foregoing, Lender shall have the right to disclose to any such actual or potential purchaser, assignee, transferee or participant all financial records, information, reports, financial statements and documents obtained in connection with this Agreement and any of the other Loan Documents or otherwise.

(b) In particular, Guarantor acknowledges and agrees that Lender and its successors and assigns may, in accordance with the Loan Agreement, engage in Secondary Market Transactions. In this regard, Guarantor shall make available to Lender all information concerning its business and operations that Lender may reasonably request that are permitted to be provided under applicable law. Lender shall be permitted to share such information permitted to be provided under applicable law with the investment banking firms, rating agencies, accounting firms, law firms, and other third-party advisory firms involved with the indebtedness secured hereby and the Loan Documents of the applicable Secondary Market Transaction. It is understood that the information provided by Guarantor to Lender may ultimately be incorporated into the offering documents for a Secondary Market Transaction and thus various investors may also have access to some or all of such information. Lender and all of the aforesaid third-party advisors and professional firms shall be entitled to rely on the information supplied by, or on behalf of, Guarantor. Guarantor shall execute and deliver to Lender and/or the prospective transferee such documentation, including but not limited to, any amendments, corrections, deletions or additions to the Loan Agreement, the Note, this Agreement and the other Loan Documents as is reasonably required by Lender and/or required by the prospective transferee; provided, however, that Guarantor shall not be required to do anything that has the effect of (a) changing the essential economic terms of the indebtedness secured hereby as set forth in the Loan Documents; or (b) imposing greater personal liability in connection with the indebtedness secured hereby than that currently set forth in the Loan Documents.

7. Special California Provisions. To the extent California law applies:

(a) Guarantor hereby also waives and agrees not to assert or take advantage of:

(i) Any defense based upon Lender’s election of any remedy against any Guarantor, including, without limitation, the defense to enforcement of this Agreement (the “Gradsky” defense based upon Union Bank v. Gradsky, 265 Cal. App. 2d 40 (1968) or subsequent cases) which, absent this waiver, Guarantor would have by virtue of an election by Lender to conduct a non-judicial foreclosure sale of the Property, it being understood by Guarantor that any such non-judicial foreclosure sale will destroy, by operation of California Code of Civil Procedure Section 580d, all rights of any party to a deficiency judgment against the Borrower, and, as a consequence, will destroy all rights which Guarantor would otherwise have (including, without limitation, the right of subrogation, the right of reimbursement, and the right of contribution) to proceed against the Borrower and to recover any such amount, and that Lender could be otherwise estopped from pursuing Guarantor for a deficiency judgment after a non-judicial foreclosure sale on the theory that a Guarantor should be exonerated if a lender elects a remedy that eliminates the Guarantor’s subrogation, reimbursement or contribution rights; and

(ii) Any rights under California Code of Civil Procedure Sections 580a and 726(b), which provide, among other things: that a creditor must file a complaint for deficiency within three (3) months of a nonjudicial foreclosure sale or judicial foreclosure sale, as applicable; that a fair market value hearing must be held; and that the amount of the deficiency judgment shall be limited to the amount by which the unpaid debt exceeds the fair market value of the security, but not more than the amount by which the unpaid debt exceeds the sale price of the security.

(b) In addition to and not in lieu of any other provisions of this Agreement, Guarantor represents and warrants and covenants as follows:

(i) The obligations of Guarantor under this Agreement shall be satisfied without demand by Lender and shall be unconditional irrespective of the genuineness, validity, regularity or enforceability of any of the Loan Documents, and without regard to any other circumstance which might otherwise constitute a legal or equitable discharge of a surety or a guarantor. Guarantor hereby waives, to the full extent permitted by applicable law, any and all benefits and defenses under California Civil Code Section 2810 and agrees that by doing so Guarantor shall be liable even if Borrower (and/or each and any Individual Borrower) had no liability at the time of execution of the Loan Documents, or thereafter ceases to be liable. Guarantor hereby waives, to the full extent permitted by applicable law, any and all benefits and defenses under California Civil Code Section 2809 and agrees that by doing so Guarantor’s liability may be larger in amount and more burdensome than that of Borrower (and/or each and any Individual Borrower). Guarantor hereby waives the benefit of all principles or provisions of law, statutory or otherwise, which are or might be in conflict with the terms of this Agreement and agrees that Guarantor’s obligations shall not be affected by any circumstances, whether or not referred to in this Agreement, which might otherwise constitute a legal or equitable discharge of a surety or a guarantor. Guarantor hereby waives, to the full extent permitted by applicable law, the benefits of any right of discharge under any and all statutes or other laws relating to guarantors or sureties and any other rights of sureties and guarantors thereunder.

(ii) In accordance with Section 2856 of the California Civil Code, Guarantor hereby waives, to the full extent permitted by applicable law, all rights and defenses arising out of an election of remedies by Lender even though that election of remedies, such as a nonjudicial foreclosure with respect to security for Guaranteed Obligations, has destroyed or

13

otherwise impaired Guarantor’s rights of subrogation and reimbursement against the principal by the operation of Section 580d of the California Code of Civil Procedure or otherwise. Guarantor hereby authorizes and empowers Lender to exercise, in its sole and absolute discretion, any right or remedy, or any combination thereof, which may then be available, since it is the intent and purpose of Guarantor that the obligations under this Agreement shall be absolute, independent and unconditional under any and all circumstances, until the full, final, indefeasible payment of the Obligations, subject to Section 2 hereof. Specifically, and without in any way limiting the foregoing, Guarantor hereby waives, to the full extent permitted by applicable law, any rights of subrogation, indemnification, contribution or reimbursement arising under Sections 2846, 2847, 2848 and 2849 of the California Civil Code or any other right of recourse to or with respect to any Individual Borrower, any general partner, member or other constituent of any Individual Borrower, any other Person, or the assets or property of any of the foregoing or to any collateral for the Loan until the Obligations have been indefeasibly paid and satisfied in full (subject to Section 2 hereof and other than contingent indemnification Obligations for which no claims have been made), and Lender has released, transferred or disposed of all its right, title and interest in such collateral or security, and there has expired the maximum possible period thereafter during which any payment made by Borrower or others to Lender with respect to the Obligations could be deemed a preference under the Bankruptcy Code. In connection with the foregoing, Guarantor expressly waives, to the full extent permitted by applicable law, any and all rights of subrogation against Borrower (and/or against any Individual Borrower), and Guarantor hereby waives, to the full extent permitted by applicable law, any rights to enforce any remedy which Lender may have against Borrower (and/or against any Individual Borrower) and any right to participate in any collateral for the Loan. Guarantor recognizes that, pursuant to Section 580d of the California Code of Civil Procedure, Lender’s realization through nonjudicial foreclosure upon any real property constituting security for Borrower’s Obligations under the Loan Documents could terminate any right of Lender to recover a deficiency judgment against Borrower (and/or against any Individual Borrower), thereby terminating subrogation rights which such parties otherwise might have against Borrower (and/or against any Individual Borrower). In the absence of an adequate waiver, such a termination of subrogation rights could create a defense to enforcement of this Agreement against such parties. Guarantor hereby unconditionally and irrevocably waives any such defense.

(iii) Without limiting the foregoing, Guarantor waives, to the full extent permitted by applicable law, all rights of subrogation, reimbursement, indemnification, and contribution and any other rights and defenses that are or may become available to Guarantor by reason of California Civil Code Sections 2787 to 2855, inclusive, until the Obligations have been indefeasibly paid and satisfied in full (subject to Section 2 hereof and other than contingent indemnification Obligations for which no claims have been made), including any and all rights or defenses Guarantor may have by reason of protection afforded to any Individual Borrower with respect to any of the obligations of Guarantor under this Agreement by reason of a nonjudicial foreclosure or pursuant to the anti-deficiency or other laws of the State of California limiting or discharging the Obligations of any Individual Borrower. Without limiting the generality of the foregoing, Guarantor hereby expressly waives, to the full extent permitted by applicable law, any and all benefits under: (i) California Code of Civil Procedure Section 580a (which Section, if Guarantor had not given this waiver, would otherwise limit Guarantor’s liability after a nonjudicial foreclosure sale to the difference between the obligations of Guarantor under this Agreement and the fair market value of the property or interests sold at such nonjudicial foreclosure sale); (ii) California Code of Civil Procedure Sections 580b and 580d (which Sections, if Guarantor had

14

not given this waiver, would otherwise limit Lender’s right to recover a deficiency judgment with respect to purchase money obligations and after a nonjudicial foreclosure sale, respectively); and (iii) California Code of Civil Procedure Section 726 (which Section, if Guarantor had not given this waiver, among other things, would otherwise require Lender to exhaust all of its security before a personal judgment could be obtained for a deficiency). Notwithstanding any foreclosure of the lien of the Collateral, whether by foreclosure or by Lender’s acceptance of an assignment in lieu of foreclosure, Guarantor shall remain bound under this Agreement.

(iv) In addition to all the other waivers agreed to and made by Guarantor as set forth in this Agreement, and pursuant to the provisions of California Civil Code, Guarantor hereby waives, to the full extent permitted by applicable law, (i) any and all rights, benefits and defenses available to Guarantor under California Civil Code Sections 2856, 2899 and 3433; (ii) any rights or defenses Guarantor may have with respect to its obligations as a guarantor by reason of any election of remedies by Lender; and (iii) all rights and defenses that Guarantor may have because the Obligations of Borrower are secured by real property. This means, among other things, that Lender may collect from Guarantor hereunder without first foreclosing on any real or personal property collateral pledged by any Individual Borrower, and that if Lender forecloses on any real property collateral pledged by any Individual Borrower: (A) the amount of the debt may be reduced only by the price for which that collateral is sold at the foreclosure sale, even if the collateral is worth more than the sale price; and (B) Lender may collect from Guarantor even if Lender, by foreclosing on the real property collateral, has destroyed any rights Guarantor may have to collect from any Individual Borrower. This is an unconditional and irrevocable waiver of any and all rights and defenses Guarantor may have because the debtor’s debt is secured by real property. These rights and defenses include, but are not limited to, any rights or defenses based upon Section 580a, 580b, 580d, or 726 of the California Code of Civil Procedure.

(c) [Reserved].

(d) Without limiting the generality of the foregoing or any other provision hereof, Guarantor expressly waives, to the full extent permitted by applicable law, any and all benefits which might otherwise be available to Guarantor under California Civil Code Sections 2809, 2810, 2819, 2839, 2845, 2849, 2850, 2899 and 3433 and California Code of Civil Procedure Sections 580a, 580b, 580d and 726, or any of such sections.

(e) Nothing herein shall be deemed to limit the right of Lender to recover in accordance with California Code of Civil Procedure Section 736 (as such Section may be amended from time to time), any costs, expenses, liabilities or damages, including reasonable out-of-pocket attorneys’ fees and costs, incurred by Lender and arising from any covenant, obligation, liability, representation or warranty contained in any indemnity agreement given to Lender, or any order, consent decree or settlement relating to the cleanup of Hazardous Materials (as such term is defined in the Environmental Indemnity) or any other “environmental provision” (as defined in such Section 736) relating to the Property or any portion thereof.

(f) The provisions of this Section 7 hereof shall survive any satisfaction and discharge of any Individual Borrower by virtue of any payment, court order or any applicable law, except the final and indefeasible payment in full of the Obligations, subject to Section 2 hereof.

15

Notwithstanding the foregoing, nothing contained in this Section 7 shall in any way be deemed to imply that California law or any other state’s law other than New York shall govern this Agreement or any of the Loan Documents in any respect, except as may be expressly set forth in the applicable Loan Documents.

8. Limitation of Liability.

(a) Notwithstanding anything herein to the contrary:

(i) in the event that Mortgage Lender and/or its designee forecloses on any Security Instrument (or accepts a deed in lieu of such foreclosure) of any Individual Property (any such event a “Mortgage Foreclosure Event”), Guarantor shall be released from the Guaranteed Obligations pertaining to such Individual Property if and only to the extent that the same arise out of acts that both (A) were not caused by any Individual Borrower, any Individual Mortgage Borrower, Guarantor or their respective Control Affiliates (as defined below) and (B) Guarantor proves first occurred after the Mortgage Foreclosure Event, in each case, as determined by a final, non-appealable order of a court of competent jurisdiction.

(ii) in the event that a receiver is appointed with respect to any Individual Property at the request of Mortgage Lender and such receiver has taken possession and exercises control over such Individual Property, Guarantor shall not be liable for Guaranteed Obligations to the extent the same were caused by the acts of such receiver or its agents.

(iii) in the event that Lender and/or its designee forecloses on any Pledged Collateral (or accepts an assignment thereof in lieu of such foreclosure) (any such event a “Foreclosure Event”), Guarantor shall be released from the Guaranteed Obligations pertaining to such Individual Borrower and the related Individual Properties indirectly owned by such Individual Borrower if and only to the extent that the same arise out of acts that both (A) were not caused by (1) any other Individual Borrower (or any Individual Mortgage Borrower owned by such other Individual Borrower) for which a Foreclosure Event has not occurred, or (2) Guarantor or its Control Affiliates and (B) Guarantor proves first occurred after the Foreclosure Event, in each case, as determined by a final, non-appealable order of a court of competent jurisdiction.

(b) For purposes of this Agreement, the term “Control Affiliates” means, as to any Individual Borrower, any Individual Mortgage Borrower or Guarantor, any Person which directly or indirectly, through one or more intermediaries, Controls, is Controlled by, or is under common Control with, any Individual Borrower, any Individual Mortgage Borrower or Guarantor, where “Control” means possession, directly or indirectly, of the power to direct or cause the direction of the management and policies of a Person, or to veto material decisions pertaining to such Person, whether through the ownership of voting securities, by contract or otherwise. In the event that Guarantor disclaims liability under this Agreement based upon the provisions of this Section 8, Guarantor shall be responsible, at its sole cost and expense, to prove such assertion.

(c) Notwithstanding anything to the contrary in this Agreement or any other Loan Document, no present or future, direct or indirect, shareholder, officer, director, employee, trustee, beneficiary, advisor, partner, member, principal, participant or agent of or in (A) Guarantor or (B) any Person that is or becomes a “Constituent Member” in Guarantor shall have any personal

16

liability, directly or indirectly, under or in connection with this Agreement, or any amendment or amendments hereto made at any time or times, heretofore or hereafter. A “Constituent Member” in Guarantor shall mean any direct shareholder, member or partner in Guarantor and any Person that, directly or indirectly through one or more other partnerships, limited liability companies, corporations or other entities, owns an interest in Guarantor.

(d) For purposes of this Agreement, neither the negative capital account of any Constituent Member in Guarantor, nor any obligation of any Constituent Member in Guarantor to restore a negative capital account or to contribute or loan capital to Guarantor or to any other Constituent Member in Guarantor shall at any time be deemed to be the property or an asset of Guarantor (or any such other Constituent Member) and neither Lender nor any of their respective successors and assigns shall have any right to collect, enforce, or proceed against any Constituent Member with respect to any such negative capital account or obligation to restore, contribute, or loan.
