F.As a condition to Administrative Agent’s and Lenders’ willingness to enter into the Second Modification, Administrative Agent and Lenders have required that Guarantor

execute and deliver this Guaranty for the benefit of Administrative Agent and Lenders, which Guaranty amends and restates in its entirety the Original Guaranty.

G.Guarantor is the owner of a direct or indirect interest in each Borrower, and Guarantor will directly benefit from Administrative Agent and Lenders modifying the Loan.

H.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)(A) and 1(d)(B) herein 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 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)(A) and 1(d)(B) herein below) for the purposes of this Guaranty.

(b)[Intentionally Omitted].

(c)[Intentionally Omitted].

(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:

A.    all amounts owing under the Environmental Indemnity Agreement if, for any reason, (i) an environmental insurance policy which is the same in all material respects as the environmental insurance policy that was approved by Administrative Agent and delivered in connection with the closing of the Loan as required under Section 2.02(b)(xx) of the Loan Agreement (“Approved Environmental Insurance Policy”) is not maintained in full force and effect (including, without limitation, by reason of Borrowers’ failure to pay the premiums with respect thereto), or (ii) Borrowers (x) fail, after written request by Administrative Agent, to direct payment of all amounts owing under such Approved Environmental Insurance Policy relating to the Mortgaged Properties to Administrative Agent or (y) disputes in writing the payment of such sums under the Approved Environmental Insurance Policy to Administrative Agent. For avoidance of doubt, Guarantor shall have no liability under clause A(i) above so long as an environmental insurance policy, which is the same in all material respects as the Approved Environmental Insurance Policy, is in full force and effect providing effective coverage for claims relating to environmental matters that occurred prior to or during a Borrower’s period of ownership of a Mortgaged Property, to the same extent as under the Approved Environmental Insurance Policy, when and if demand is made by Administrative Agent under the Environmental Indemnity Agreement, whether or not the claim relating to any such environmental matter is a covered claim under such environmental insurance policy (unless such claim was a covered claim under the Approved Environmental Insurance Policy); and

B.    all losses (which shall include, without limitation, attorneys’ fees and costs of defense) sustained or incurred by Administrative Agent and/or Lenders by reason of any failure to maintain in full force and effect (which Guarantor hereby covenants to so do) an environmental insurance policy which is the same in all material respects as the Approved Environmental Insurance Policy for a period of two years following the repayment of the Obligations in full. As used in this subsection B, “full force and effect” shall include reference to an environmental insurance policy for events occurring prior to or during a Borrower’s period of ownership of a Mortgaged Property and that has coverage under an extended reporting period of no less than two (2) years following the repayment of the Obligations in full. For avoidance of doubt, Guarantor shall have no liability under this subsection B so long as an environmental insurance policy, which is the same in all material respects as the Approved Environmental Insurance Policy, is in full force and effect providing coverage under an extended reporting period for claims relating to environmental matters that occurred prior to or during a Borrower’s period of ownership of the Mortgaged Property, to the same extent as under the Approved Environmental Insurance Policy, when and if demand is made by Administrative Agent under the Guaranty, whether or not the claim relating to any such environmental matter is a covered claim under such environmental insurance policy (unless such claim was a

covered claim under the Approved Environmental Insurance Policy). For purposes of clarification (but subject to Section 27 below), Guarantor’s liability under this subsection B shall not be terminated or otherwise affected even if a Borrower’s obligations under the Environmental Indemnity Agreement are terminated in accordance with Section 10 of the Environmental Indemnity.

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).

(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.

(c)Guarantor Prohibited Distributions. Guarantor shall not make any distributions; provided, however, so long as no Default or Unmatured Default exists, Guarantor will be permitted to make distributions (i) to the extent necessary to maintain the REIT status of any of its direct or indirect owners that are REITs, and (ii) for Death and Disability Redemptions (as defined in the Second Modification); provided, however, amounts distributed for Death and Disability Redemptions shall not exceed $250,000, in the aggregate, for any calendar year.

account at, and controlled by, Administrative Agent established for the purpose of holding the Guarantor Excess Cash (the “Guarantor Excess Cash Account”) (and any interest that may accrue on the funds in such Guarantor Excess Cash Account shall accrue for the benefit of Guarantor so long as no Default exists) or (ii) pay to Administrative Agent all Guarantor Excess Cash to be applied in repayment of the Obligations (as defined in the Loan Agreement) in such order as Administrative Agent shall determine, or a combination of (i) and (ii) in Guarantor’s sole and absolute discretion.

(b)Guarantor shall (i) complete and duly execute and deliver (as applicable) all documentation reasonably required by Administrative Agent to establish and pledge to Administrative Agent, for the benefit of the Lenders, the Guarantor Excess Cash Account (including Administrative Agent’s standard form of deposit account control agreement, blocked account agreement, or similar agreement, which shall be in all material respects consistent with the provisions of this Agreement and which shall be subject to any modification as may be agreed upon by Borrower and Administrative Agent), and (ii) otherwise reasonably cooperate with Administrative Agent in all reasonable respects to establish the Guarantor Excess Cash Account, pledge it to Administrative Agent, for the benefit of Lenders, and perfect such pledge, within ten (10) Business Days after Administrative Agent provides Guarantor with such documentation. Guarantor hereby grants to Administrative Agent a security interest in the Guarantor Excess Cash Account and all funds on deposit therein as additional security for the Obligations and agrees that it shall not, without obtaining the prior express written consent of Administrative Agent, further pledge, assign or grant any security interest in the Guarantor Excess Cash Account. Guarantor agrees to hold in trust for the benefit of Administrative Agent on behalf of the Lenders, all Guarantor Excess Cash in its possession prior to the deposit of such Guarantor Excess Cash into the Guarantor Excess Cash Account. This Agreement is, among other things, intended by the parties to be a security agreement for purposes of the UCC.

No Guarantor hereunder shall be deemed to be a guarantor of any Swap Obligations if such Guarantor is not an “Eligible Contract Participant” as defined in §1(a)(18) of the Commodity Exchange Act and the applicable rules issued by the Commodity Futures Trading Commission and/or the Securities and Exchange Commission (collectively, and as now or hereafter in effect, the “ECP Rules”) to the extent that the providing of such guaranty

by such Guarantor would violate the ECP Rules or any other applicable law or regulation. This paragraph shall not affect any obligations of Guarantor other than Swap Obligations, nor shall it affect the obligations of any Guarantor who qualifies as an “Eligible Contract Participant”.

Section 22. Invalid Provisions. If any provision of this Guaranty is held to be illegal, invalid, or unenforceable under present or future laws effective during the term of this Guaranty, such provision shall be fully severable and this Guaranty shall be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part of this Guaranty, and the remaining provisions of this Guaranty shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable provision or by its severance from this Guaranty, unless such continued effectiveness of this Guaranty, as modified, would be contrary to the basic understandings and intentions of the parties as expressed herein.

Section 23. ENTIRETY. THIS GUARANTY AND THE OTHER LOAN DOCUMENTS EXECUTED BY GUARANTOR EMBODY THE FINAL, ENTIRE AGREEMENT OF GUARANTOR, ADMINISTRATIVE AGENT AND THE LENDERS WITH RESPECT TO THE SUBJECT MATTER HEREOF AND THEREOF AND SUPERSEDES ANY AND ALL PRIOR COMMITMENTS, AGREEMENTS, REPRESENTATIONS, AND UNDERSTANDINGS, WHETHER WRITTEN OR ORAL, RELATING TO THE SUBJECT MATTER HEREOF AND THEREOF. 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. THERE ARE NO ORAL AGREEMENTS BETWEEN GUARANTOR, ADMINISTRATIVE AGENT AND THE LENDERS.

Section 24. WAIVER OF JURY TRIAL AND JUDICIAL REFERENCE PROVISION.

Section 25. 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 26. 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 27. 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)A and 1(d)B 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.
