J.Any capitalized term used and not defined in this Guaranty shall have the meaning given to such term in the Loan Agreement. This Guaranty is one of the Loan Documents described in the Loan Agreement.

NOW, THEREFORE, as an inducement to Administrative Agent and Lenders to modify the Loan to Borrowers and enter into the Loan Agreement, and for other good and valuable consideration, the receipt and legal sufficiency of which are hereby acknowledged, Guarantor agrees with Administrative Agent and the Lenders, as follows:

Section 1. Guaranty of Obligations.

(a)    Guarantor hereby absolutely, irrevocably and unconditionally guarantees to Administrative Agent and Lenders, the payment of the Obligations (but expressly excluding any amounts owing under the Environmental Indemnity Agreement, except as expressly provided in Sections 1(d)(7) and 1(d)(8) herein below), subject to the limitations set forth in subsection (b) below, whether now or hereafter arising, as and when the same shall be due and payable, whether by lapse of time, by acceleration of maturity or otherwise. This Guaranty is a guaranty of payment and not of collection only. Administrative Agent and Lenders shall not be required to exhaust any right or remedy or take any action against Borrowers or any other person or entity or any collateral. Guarantor agrees that, as between Guarantor and Administrative Agent and Lenders, the Obligations may be declared to be due and payable for the purposes of this Guaranty (provided Guarantor’s liability with respect thereto shall at all times remain subject to the limitations set forth in this Section 1(b)) notwithstanding any stay, injunction or other prohibition which may prevent, delay or vitiate any declaration as regards Borrowers (or any of them) and that in the event of a declaration or attempted declaration, the Obligations shall immediately become due and payable by Guarantor (but expressly excluding any amounts owing under the Environmental Indemnity Agreement, except as expressly provided in Sections 1(d)(7) and 1(d)(8) herein below) for the purposes of this Guaranty.

(b)    Notwithstanding anything herein to the contrary, the liability of Guarantor hereunder shall not exceed the Base Guaranteed Amount (defined below as the same shall be determined from time to time), plus the amounts (if any) due under paragraphs (c) and (d) and Section 15 below (if and to the extent applicable).

For the purposes of this Guaranty, “Base Guaranteed Amount” shall mean an amount equal to twenty-five percent (25.0%) of all amounts owing under the Loan (not to exceed $18,200,000.00, or, if the Aggregate Commitment amount is permanently reduced as set forth in the Loan Agreement, 25% percent of the then-existing Aggregate Commitment amount), such amount calculated based on the outstanding amounts owing as of the date the Note becomes due and payable in full (whether at maturity or by acceleration or otherwise) (the “Due Date”). In addition to the Base Guaranteed Amount, Guarantor shall continue to be liable for, and shall have at all times under this Guaranty a continuing obligation to pay Lender 100% of the amounts specified in paragraphs (c) and (d) and Section 15 below, if and to the extent applicable.

In determining the Base Guaranteed Amount, no payments or recoveries from any source whatsoever (including without limitation payments received from Borrowers and proceeds from the foreclosure sale or other liquidation of collateral for the Loan, or any credit bids made by Administrative Agent at any foreclosure sale) received by Administrative Agent or Lenders shall be applied to reduce the Base Guaranteed Amount. Guarantor’s maximum liability under this Guaranty shall be reduced only by payments received from Guarantor under this Guaranty following the Due Date from its own funds (and not, as noted above, from liquidation of collateral). Additional advances (such as protective advances) made after the Due Date shall increase the Base Guaranteed Amount by an amount equal to twenty-five percent (25.0%) of the amount advanced (subject to the maximum capped amount specified above).

(c)    Notwithstanding anything herein to the contrary, at all times until the Obligations have been paid in full and the Loan Documents and any applicable Swap Agreement are no longer in effect, Guarantor shall (in addition to those specified in Section 1(b) above) have full, complete, and unlimited liability for the payment and performance of all of the Obligations if any of the foregoing shall occur:

(d)    In addition, notwithstanding anything herein to the contrary, at all times until the Obligations have been paid in full and the Loan Documents and any applicable Swap Agreement are no longer in effect, Guarantor guarantees to Administrative Agent and the Lenders, the full and prompt payment of, and agrees to pay protect, guarantee, indemnify, defend and hold harmless Administrative Agent and Lenders from and against, any actual liability, loss, damage, costs and expenses (including legal fees) suffered by Administrative Agent or the Lenders, and caused by or related to or as a result of the following:

Agreement at any time prior to a transfer (that is not in violation of the Loan Documents) of ownership of a Mortgaged Property from a Borrower to a new owner, except to the extent (i) any such failure occurred by reason of the failure to pay the insurance premiums pertaining thereto, and (ii) the failure to pay such premiums occurred because there was insufficient cash flow from the Mortgaged Properties to pay such premiums, with a payment of each such premium to be the top priority in the application of any such cash flow, and such cash flow was available to a Borrower and not seized by a receiver or other third party creditor); or the application or misapplication of any insurance proceeds or condemnation awards by a Borrower in violation of the terms of the Loan Documents or any applicable Swap Agreement;

9.    amounts (if any) owing to Administrative Agent and Lenders under Section 15 below.

It is understood that the obligations of Borrowers to Administrative Agent and the Lenders may at any time and from time to time exceed the liability of Guarantor hereunder without impairing this Guaranty and Guarantor, Administrative Agent and Lenders agree, as between themselves, that regardless of the manner of application of payments made by Borrowers to Administrative Agent and the Lenders, all such payments shall be deemed to be applied first to the portion of the obligations of Borrowers which are not guaranteed hereunder and last to the portion of the such obligations which are guaranteed hereunder.

Section 2.     Guaranty Absolute. Guarantor guarantees that the Obligations shall be paid strictly in accordance with the terms of the Loan Documents and any applicable Swap Agreement. The liability of Guarantor under this Guaranty is absolute and unconditional irrespective of: (a) any change in the time, manner or place of payment of, or in any other term of, all or any of the Obligations, or any other amendment or waiver of or any consent to departure from any of the terms of any Loan Document or any applicable Swap Agreement, including any increase or decrease in the rate of interest thereon; (b) any release or amendment or waiver of, or consent to departure from, or failure to act by Administrative Agent or the Lenders with respect to, any other guaranty or support document, or any exchange, release or non‑perfection of, or failure to act by

Administrative Agent or the Lenders, with respect to, any collateral, for all or any of the Obligations; (c) any present or future law, regulation or order of any jurisdiction (whether of right or in fact) or of any agency thereof purporting to reduce, amend, restructure or otherwise affect any term of the Obligations or any Loan Document or any applicable Swap Agreement; (d) any change in the existence, structure, or ownership of any Borrower; (e) without being limited by the foregoing, any lack of validity or enforceability of any Loan Document or any applicable Swap Agreement; and (f) any other setoff, recoupment, defense or counterclaim whatsoever (in any case, whether based on contract, tort or any other theory) with respect to the Loan Documents and any applicable Swap Agreement or the transactions contemplated thereby which might constitute a legal or equitable defense available to, or discharge of, a Borrower or a guarantor.

Section 3.     Guaranty Irrevocable. This Guaranty is a continuing guaranty of the payment of all Obligations now or hereafter existing and shall remain in full force and effect until payment in full of all Obligations and other amounts payable under this Guaranty and until the Loan Documents and any applicable Swap Agreement are no longer in effect.

Section 4.     Waiver of Certain Rights and Notices. To the fullest extent not prohibited by applicable law, except as specifically provided herein, Guarantor hereby waives and agrees not to assert or take advantage of (a) any right to require Administrative Agent, for the benefit of the Lenders, to proceed against or exhaust its recourse against Borrowers, any other guarantor or endorser, or any security or collateral held by Administrative Agent or Lenders at any time or to pursue any other remedy in its power before proceeding against Guarantor hereunder; (b) the defense of the statute of limitations in any action hereunder; (c) any defense that may arise by reason of (i) the incapacity, lack of authority, death or disability of a Borrower, Guarantor or any other or others, (ii) the revocation or repudiation hereof by Guarantor or the revocation or repudiation of any of the Loan Documents by a Borrower or any other or others, (iii) the failure of Administrative Agent, on behalf of the Lenders, to file or enforce a claim against the estate (either in administration, bankruptcy or any other proceeding) of a Borrower or any other or others, (iv) the unenforceability in whole or in part of any Loan Document or any applicable Swap Agreement, (v) Administrative Agent’s or a Lender’s election in any proceeding instituted under the federal Bankruptcy Code, of the application of Section 1111(b)(2) of the federal Bankruptcy Code, or (vi) any borrowing or grant of a security interest under Section 364 of the federal Bankruptcy Code; (d) presentment, demand for payment, protest, notice of discharge, notice of acceptance of this Guaranty, and indulgences and notices of any other kind whatsoever; (e) any defense based upon an election of remedies by Administrative Agent, on behalf of the Lenders, which destroys or otherwise impairs the subrogation rights of Guarantor or the right of Guarantor to proceed against Borrowers for reimbursement, or both; (f) any defense based upon any taking, modification or release of any collateral, or any failure to perfect any security interest in, or the taking of or failure to take any other action with respect to any collateral securing payment or performance of the Obligations; (g) any right to require marshaling of assets and liabilities, sale in inverse order of alienation, notice of acceptance of this Guaranty and of any obligations to which it applies or may apply; and (h) any rights or defenses based upon an offset by Guarantor against any obligation now or hereafter owed to Guarantor by Borrowers; it being the intention hereof that Guarantor shall remain liable hereunder to the extent set forth herein, notwithstanding any act, omission or thing which might otherwise operate as a legal or equitable discharge of Guarantor, until the termination of this Guaranty under Section 3. Guarantor waives presentment, demand, notice of

dishonor, protest, notice of acceptance of this Guaranty or incurrence of any of the Obligations and any other formality with respect to any of the Obligations or this Guaranty.

Guarantor hereby waives: (a) any defense based upon the application by Borrowers of any proceeds relating to the Loan Agreement for purposes other than the purposes represented by Borrowers to Administrative Agent and Lenders, or intended or understood by Administrative Agent and Lenders or Guarantor; (b) any defense based upon Administrative Agent’s or any Lender’s failure to disclose to Guarantor any information concerning a Borrower’s financial condition or any other circumstances bearing on a Borrower’s ability to pay all sums payable under the Loan Agreement; (c) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in any other respects more burdensome than that of a principal; (d) any rights of subrogation, reimbursement, indemnification and contribution, and any other rights and defenses that are or may become available to Guarantor by reason of Sections 2787 to 2855, inclusive, of the California Civil Code, any right to enforce any remedy which Administrative Agent and Lenders may have against a Borrower and any right to participate in, or benefit from, any security for the Loan Agreement now or hereafter held by Administrative Agent or Lenders; (e) presentment, demand, protest and notice of any kind (other than when expressly required under the Loan Documents); (f) the benefit of any statute of limitations affecting the liability of Guarantor hereunder or the enforcement hereof; (g) any right to require Administrative Agent, on behalf of the Lenders, to institute suit or exhaust remedies against a Borrower or others liable for any Obligations, to enforce Administrative Agent’s and Lenders’ rights against any collateral which shall have been given to secure the Obligations to enforce Administrative Agent’s and Lenders’ rights against any other guarantors of such indebtedness, to join Borrowers or any others liable on such Obligations in any action seeking to enforce this Guaranty, to resort to any other means of obtaining payment of such Obligations; (h) notices of disbursement of proceeds, acceptance hereof, proof of non-payment, default under any document, notices and demands of any kind; and (i) the invalidity illegality or unenforceability of all or any portion of the indebtedness guaranteed hereby or any of the Loan Documents for any reason whatsoever, including that interest on such indebtedness violates applicable usury laws, that the Borrowers or others liable for all or a portion thereof have valid defenses, claims or offsets to all or a portion of such indebtedness, or that the Loan Documents have been forged or otherwise are irregular or not genuine or authentic (it being agreed that Guarantor shall remain liable under this Guaranty regardless of whether Borrowers or any other person shall be found not liable for repayment of all or a portion of such indebtedness). Guarantor further waives any and all rights and defenses that Guarantor may have because Borrowers’ debt is secured by real property; this means, among other things, that (1) Administrative Agent and Lenders may collect or receive performance from Guarantor without first foreclosing on any real or personal property collateral pledged by any Borrower; (2) if Administrative Agent forecloses on any real property collateral pledged by a Borrower, then (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) Administrative Agent and Lenders may collect or receive performance from Guarantor even if Administrative Agent, by foreclosing on the real property collateral, has destroyed any right Guarantor may have to collect from a Borrower. The foregoing is an unconditional and irrevocable waiver of any rights and defenses Guarantor may have because Borrowers’ debt is secured by real property. These rights and defenses include, but are not limited to, any rights or defenses based upon Sections 580a, 580b, 580d, or 726 of the California Code of Civil Procedure. Without limiting the generality of the foregoing or any other provision hereof,

Guarantor further expressly waives (i) all rights and defenses arising out of an election of remedies by the Administrative Agent or Lenders, even though that election of remedies, such as non-judicial foreclosure with respect to security for Borrowers’ obligations, has destroyed Guarantor’s rights of subrogation and reimbursement against the principal by the operation of Section 580(d) of the California Code of Civil Procedure or otherwise and (ii) any and all other rights and defenses to the extent permitted by law. Guarantor hereby waives any right it might otherwise have under Section 2822 of the California Civil Code or similar law or otherwise to have Borrowers designate the portion of any such obligation to be satisfied in the event that a Borrower provides partial satisfaction of such obligation. Guarantor acknowledges and agrees that Borrowers may already have agreed with Administrative Agent and Lenders, or may hereafter agree, that in any such event the designation of the portion of the obligation to be satisfied shall, to the extent not expressly made by the terms of the Loan Documents, be made by Administrative Agent and Lenders rather than by Borrowers. Finally, Guarantor agrees that the performance of any act or any payment which tolls any statute of limitations applicable to the Loan Documents shall similarly operate to toll the statute of limitations applicable to Guarantor’s liability hereunder.

Section 5.     Reinstatement. This Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Obligations is rescinded or must otherwise be returned by Administrative Agent or Lenders on the insolvency, bankruptcy or reorganization of a Borrower or otherwise, all as though the payment had not been made, whether or not Administrative Agent is in possession of this Guaranty.

Section 6.     Subrogation. Guarantor shall not exercise any rights which it may acquire by way of subrogation, reimbursement or contribution, as a result of any payment made under this Guaranty or otherwise, until all the Obligations have been paid in full and the Loan Documents and any Swap Agreement are no longer in effect. If any amount is paid to Guarantor by a Borrower on account of such rights prior to such time, the amount shall be held in trust for the benefit of the Administrative Agent and Lenders and shall be promptly paid to Administrative Agent, for the benefit of the Lenders, to be credited and applied to the Obligations, whether matured or unmatured or absolute or contingent, in accordance with the terms of the Loan Documents and any applicable Swap Agreement. If Guarantor makes payment to Administrative Agent, for the benefit of the Lenders, of all or any part of the Obligations and all the Obligations are paid in full and the Loan Documents and any applicable Swap Agreement are no longer in effect, Administrative Agent shall, at Guarantor’s request, execute and deliver to Guarantor appropriate documents, without recourse and without representation or warranty, necessary to evidence the transfer by subrogation to Guarantor of the interest in the Obligations resulting from the payment.

Section 7.     Subordination. Without limiting Administrative Agent’s or Lenders’ rights under any other agreement, any liabilities owed by Borrowers to Guarantor in connection with any extension of credit or financial accommodation by Guarantor to or for the account of a Borrower, including but not limited to interest accruing at the agreed contract rate after the commencement of a bankruptcy or similar proceeding, are hereby subordinated to the Obligations, and such liabilities of Borrowers to Guarantor, if Administrative Agent so requests, shall be collected, enforced and received by Guarantor as trustee for the Lenders and shall be paid over to Administrative Agent, for the benefit of the Lenders, on account of the Obligations but without reducing or affecting in any manner the liability of Guarantor under the other provisions of this Guaranty.

Section 8.     Certain Taxes. Guarantor further agrees that all payments to be made hereunder shall be made without setoff or counterclaim and free and clear of, and without deduction for, any taxes, levies, imposts, duties, charges, fees, deductions, withholdings or restrictions or conditions of any nature whatsoever now or hereafter imposed, levied, collected, withheld or assessed by any country or by any political subdivision or taxing authority thereof or therein (“Taxes”). If any Taxes are required to be withheld from any amounts payable to Administrative Agent on behalf of Lenders, hereunder, the amounts so payable to Administrative Agent on behalf of Lenders, shall be increased to the extent necessary to yield to Administrative Agent on behalf of Lenders, (after payment of all Taxes) the amounts payable hereunder in the full amounts so to be paid. Whenever any Tax is paid by Guarantor, as promptly as possible thereafter, Guarantor shall send Administrative Agent an official receipt showing payment thereof, together with such additional documentary evidence as may be required from time to time by Administrative Agent.

Section 9.     Representations and Warranties. Guarantor represents and warrants that: (a) this Guaranty (i) has been authorized by all necessary action; (ii) to Guarantor’s knowledge, does not violate any agreement, instrument, law, regulation or order applicable to Guarantor; (iii) to Guarantor’s knowledge, does not require the consent or approval of any person or entity, including but not limited to any governmental authority, or any filing or registration of any kind; and (iv) is the legal, valid and binding obligation of Guarantor enforceable against Guarantor in accordance with its terms, except to the extent that enforcement may be limited by applicable bankruptcy, insolvency and other similar laws affecting creditors’ rights generally; and (b) in executing and delivering this Guaranty, Guarantor has (i) without reliance on Administrative Agent or any Lender or any information received from Administrative Agent or any Lender and based upon such documents and information it deems appropriate, made an independent investigation of the transactions contemplated hereby and each Borrower, each Borrower’s business, assets, operations, prospects and condition, financial or otherwise, and any circumstances which may bear upon such transactions, Borrowers or the obligations and risks undertaken herein with respect to the Obligations; (ii) adequate means to obtain from Borrowers on a continuing basis information concerning Borrowers; (iii) full and complete access to the Loan Documents, any applicable Swap Agreement and any other documents executed in connection with the Loan Documents; and (iv) not relied and will not rely upon any representations or warranties of Administrative Agent or any Lender not embodied herein or any acts heretofore or hereafter taken by Administrative Agent or any Lender (including but not limited to any review by Administrative Agent or any Lender of the affairs of Borrowers).

Section 10.     Financial Reports and Covenants.

(a)    Guarantor shall keep adequate books and records of account in accordance with methods acceptable to Administrative Agent, consistently applied and shall furnish to Administrative Agent the financial statements, certificates and other information described in Section 4.09(b) of the Loan Agreement as and when required by said Section 4.09(b).

(b)    Administrative Agent and its accountants shall have the right to examine, upon at least 24 hours’ prior written notice to Guarantor (provided no advance notice is required during the existence of a Default), the records, books, management and other papers of Guarantor which reflect upon its financial condition, at any Mortgaged Property or at any office regularly maintained by Guarantor where the books and records are located. Such examination shall be at

Administrative Agent’s and Lenders’ costs unless (i) a Default exists, (ii) Administrative Agent or any Lender has reason to believe any information provided to Administrative Agent or Lenders, by Guarantor may be incorrect or misleading in any material respect, or (iii) Administrative Agent, on behalf of the Lenders, is conducting such examination pursuant to its obligations under any applicable laws or regulations (provided, with respect to subsection (iii), in no event shall Guarantor be obligated to reimburse Administrative Agent or Lenders for such costs and expenses for more than one examination per year). Administrative Agent and its accountants shall have the right to make copies and extracts from the foregoing records and other papers. In addition, Administrative Agent and its accountants shall have the right to examine and audit the books and records of Guarantor pertaining to the income, expenses and operation of the Mortgaged Properties during reasonable business hours at any office of Guarantor where the books and records are located.

Section 11.     Remedies Generally. The remedies provided in this Guaranty are cumulative and not exclusive of any remedies provided by law.

Section 12.     Setoff. If a Default shall have occurred and be continuing, Administrative Agent and each Lender and each of their respective Affiliates are hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time owing by such party to or for the credit or the account of Guarantor against any of and all the obligations of Guarantor under this Guaranty, irrespective of whether or not Administrative Agent or such Lender shall have made any demand under this Guaranty and although such obligations may be unmatured. The rights of Administrative Agent and each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which such parties may have.

Section 13.     Formalities. Guarantor waives presentment, demand, notice of dishonor, protest, notice of acceptance of this Guaranty or incurrence of any of the Obligations and any other formality with respect to any of the Obligations or this Guaranty.

Section 14.     Amendments and Waivers. No amendment or waiver of any provision of this Guaranty, nor consent to any departure by Guarantor therefrom, shall be effective unless it is in writing and signed by Administrative Agent, and then the waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. No failure on the part of Administrative Agent to exercise, and no delay in exercising, any right under this Guaranty shall operate as a waiver or preclude any other or further exercise thereof or the exercise of any other right.

Section 15.     Expenses. Guarantor shall reimburse Administrative Agent and the Lenders on demand for all costs, expenses and charges (including without limitation reasonable fees and charges of external legal counsel for Administrative Agent and the Lenders) incurred by Administrative Agent and the Lenders in connection with the performance or enforcement of this Guaranty. The obligations of Guarantor under this Section shall survive the termination of this Guaranty.

Section 16.     Assignment. This Guaranty shall be binding on, and shall inure to the benefit of Guarantor, Administrative Agent, the Lenders and their respective successors, assigns, estates and personal representatives; provided that Guarantor may not assign or transfer its rights or obligations under this Guaranty. Without limiting the generality of the foregoing: (a) the obligations of Guarantor under this Guaranty shall continue in full force and effect and shall be binding on any successor partnership and on previous partners and their respective estates if Guarantor is a partnership, regardless of any change in the partnership as a result of death, retirement or otherwise; and (b) Administrative Agent and each Lender may assign, sell participations in or otherwise transfer their respective rights under the Loan Documents and any applicable Swap Agreement to any other person or entity in accordance with the terms of the Loan Agreement and any applicable Swap Agreement, and the other person or entity shall then become vested with all the rights granted to Administrative Agent or such Lender in this Guaranty or otherwise.

THIS GUARANTY AND THE OTHER LOAN DOCUMENTS EXECUTED BY GUARANTOR ARE INTENDED BY GUARANTOR, ADMINISTRATIVE AGENT AND THE LENDERS AS A FINAL AND COMPLETE EXPRESSION OF THE TERMS HEREOF AND THEREOF, AND NO COURSE OF DEALING AMONG GUARANTOR, ADMINISTRATIVE AGENT AND THE LENDERS, NO COURSE OF PERFORMANCE, NO TRADE PRACTICES, AND NO EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OR DISCUSSIONS OR OTHER EXTRINSIC EVIDENCE OF ANY NATURE SHALL BE USED TO CONTRADICT, VARY, SUPPLEMENT OR MODIFY ANY TERM OF THIS GUARANTY OR ANY OTHER LOAN DOCUMENT EXECUTED BY GUARANTOR.

Section 23.     WAIVER OF JURY TRIAL AND JUDICIAL REFERENCE PROVISION.

Section 24.     WAIVER OF SPECIAL DAMAGES. Guarantor agrees that neither Administrative Agent nor any Lender shall have any liability to Guarantor (whether sounding in tort, contract or otherwise) for losses suffered by Guarantor in connection with, arising out of, or in any way related to, the transactions contemplated and the relationship established by the Loan Documents and any applicable Swap Agreement, or any act, omission or event occurring in connection therewith, unless such losses result from the gross negligence or willful misconduct of the party from which recovery is sought or from a breach of any Loan Document or any applicable Swap Agreement by such party. TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW, GUARANTOR SHALL NOT ASSERT, AND HEREBY WAIVES, ANY CLAIM AGAINST ADMINISTRATIVE AGENT AND EACH OF THE LENDERS ON ANY THEORY OF LIABILITY, FOR SPECIAL, INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGES (AS OPPOSED TO DIRECT OR ACTUAL DAMAGES) ARISING OUT OF, IN CONNECTION WITH, OR AS A RESULT OF, THIS GUARANTY, ANY OTHER LOAN DOCUMENT OR ANY SWAP AGREEMENT, THE OBLIGATIONS OR THE USE OF THE PROCEEDS THEREOF.

Section 25.     Limitation on Liability. Notwithstanding the foregoing or anything to the contrary in this Guaranty, under no circumstances shall Administrative Agent or the Lenders have any recourse against, nor shall there be any personal liability to, the members of Guarantor, or to any shareholders, members or partners (direct or indirect) for any obligations of Guarantor hereunder. For purposes of clarification, in no event shall the above language limit, reduce or otherwise affect any 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.

Section 26.     Termination of Environmental Liability. Notwithstanding anything to the contrary stated in this Guaranty, if the conditions set forth in Sections 10.1 through 10.5 of the Environmental Indemnity Agreement are satisfied (i.e., all conditions for Borrowers’ release of their liability under the Environmental Indemnity Agreement other than the expiration of the two year period have been satisfied), Guarantor’s liability under Sections 1(d)7 and 1(d)8 of this Guaranty with respect to environmental liability shall automatically terminate.

IN WITNESS WHEREOF, Guarantor has caused this Guaranty to be duly executed and delivered by its duly authorized officer as of the date first above written.
