ARTICLE I

NATURE AND SCOPE OF GUARANTY

1.1Guaranty of Obligations. Guarantor hereby absolutely, irrevocably and unconditionally guarantees to Lender the full and timely payment and performance of all of the Guaranteed Obligations as and when the same shall be due and payable, whether by lapse of time, by acceleration of maturity or otherwise. Guarantor hereby absolutely, irrevocably and unconditionally covenants and agrees that it is liable for the Guaranteed Obligations as primary obligor.

1.2Definition of Guaranteed Obligations. As used herein, the term “Guaranteed Obligations” means, collectively, the (i) payment and performance of all of the obligations, representations, covenants, warranties and liabilities of Borrower arising under the Loan Agreement and Loan Documents, but expressly excluding any of such obligations, representations, covenants, warranties and liabilities to the extent covered by that certain Environmental Indemnity Agreement of even date herewith executed by KBS Acquisition Sub, LLC, in favor of Lender and/or to the extent relating to environmental matters or hazardous substances, and (ii) payment of any and all losses, damages, claims, expenses, deficiencies, liabilities and costs (including, without limitation, reasonable attorneys’ fees and disbursements) incurred, suffered or sustained by Agent and/or its successors and assigns as a result of or arising out of, in connection with or resulting from, the enforcement of this Agreement against Guarantor. Notwithstanding the foregoing, the Guaranteed Obligations shall not exceed the value of the equity interests owned (directly and/or indirectly) by Guarantor.

1.3Nature of Guaranty. This Guaranty is an irrevocable, absolute and continuing guaranty of payment and not a guaranty of collection. No exculpatory language contained in any of the other Loan Documents shall in any event or under any circumstances modify, qualify or affect the personal recourse obligations and liabilities of Guarantor hereunder. This Guaranty may not be revoked by Guarantor and shall continue to be effective with respect to the Guaranteed Obligations arising or created after any attempted revocation by Guarantor and, if Guarantor is a natural person, after Guarantor’s death, in which event this Guaranty shall be binding upon Guarantor’s estate and Guarantor’s legal representatives and heirs. It is the intent of Guarantor and Lender that the obligations and liabilities of Guarantor hereunder are absolute and unconditional under any and all circumstances and that so long as any portion of the Indebtedness shall be outstanding, such obligations and liabilities shall not be discharged or released in whole or in part, by any act or occurrence (including, without limitation, the fact that at any time or from time to time the Indebtedness or the Guaranteed Obligations may be increased or reduced) which might, but for the provisions of this Guaranty, be deemed a legal or equitable discharge or release of Guarantor. This Guaranty may be enforced by Lender and any subsequent holder of the Note or any part thereof and shall not be discharged by the assignment or negotiation of all or any part of the Note.

1.4Guaranteed Obligations Not Reduced by Set-Off. The Guaranteed Obligations and the liabilities and obligations of Guarantor to Lender hereunder shall not be reduced, discharged or released because or by reason of any existing or future set-off, offset, claim or defense of any kind or nature other than the defense that such Guaranteed Obligations

have been paid in full by Borrower in accordance with the Loan Documents which Borrower, Guarantor or any other Person has or may hereafter have against Lender or against payment of the Indebtedness or the Guaranteed Obligations, whether such set-off, offset, claim or defense arises in connection with the Guaranteed Obligations or otherwise.

1.5No Duty to Pursue Others; No Duty to Mitigate. It shall not be necessary for Lender (and Guarantor hereby waives any rights which Guarantor may have to require Lender) to take any action, obtain any judgment or file any claim prior to enforcing this Guaranty, including, without limitation, to (i) institute suit or otherwise enforce Lender’s rights, or exhaust its remedies, against Borrower or any other Person liable on all or any part of the Indebtedness or the Guaranteed Obligations, or against any other Person, (ii) enforce Lender’s rights, or exhaust any remedies available to Lender, against any collateral which shall ever have been given to secure all or any part of the Indebtedness or the Guaranteed Obligations, (iii) join Borrower or any other Person liable on the Guaranteed Obligations in any action seeking to enforce this Guaranty or (iv) resort to any other means of obtaining payment of all or any part of the Indebtedness or the Guaranteed Obligations. Lender shall not be required to mitigate damages or take any other action to reduce, collect or enforce the Guaranteed Obligations.

1.6Payment by Guarantor. If all or any part of the Guaranteed Obligations shall not be punctually paid or performed when due, whether at demand, maturity, acceleration or otherwise, Guarantor shall promptly, upon written demand (made in accordance with Section 5.14), but in any event within 5 Business Days from the date such demand is made by Lender and without presentment, protest, notice of protest, notice of non-payment, notice of intention to accelerate the maturity, notice of acceleration of the maturity or any other notice whatsoever, pay in lawful money of the United States of America, the amount due thereon to Lender. Amounts not paid when due hereunder shall accrue interest at the Default Rate, unless such amounts already include interest at the Default Rate pursuant to the terms of the other Loan Documents. Such demands may be made at any time coincident with or after the time for payment of all or any part of the Guaranteed Obligations and may be made from time to time with respect to the same or different Guaranteed Obligations.

1.7Application of Payments. If, at any time, there is any Indebtedness or obligations of Borrower to Lender which is not guaranteed by Guarantor, Lender, without in any manner impairing its rights hereunder, may, at its option, apply all amounts realized by Lender from any collateral or security held by Lender first to the payment of such unguaranteed Indebtedness or obligations, with the remaining amounts, if any, to then be applied to the payment of the Indebtedness or obligations guaranteed by Guarantor.

1.8Waivers.

(a)Guarantor hereby assents to all of the terms and agreements heretofore or hereafter made by Borrower with Lender (including, without limitation, the provisions of the Loan Documents) and hereby waives diligence, presentment, protest, demand on Borrower for payment or otherwise, filing of claims, requirement of a prior proceeding against Borrower and all notices (other than notices expressly provided for hereunder or required to be delivered under applicable law), including, without limitation, notice of:

(i)the acceptance of this Guaranty;

(ii)the present existence or future incurring of all or any part of the Indebtedness, or any future change to the time, manner or place of payment of, or in any other term of all of any part of the Indebtedness or the Guaranteed Obligations;

(iii)any amendment, modification, replacement or extension of any of the Loan Documents;

(iv)the execution and delivery by Borrower and Lender of any other loan or credit agreement or of Borrower’s execution and delivery of any promissory note or other documents arising under the Loan Documents or in connection with the Property;

(vi)the sale or foreclosure (or posting or advertising for sale or foreclosure), or assignment-in-lieu of foreclosure, of any collateral for the Guaranteed Obligations;

(vii)any protest, proof of non-payment or default by Borrower, or the occurrence of a breach or an Event of Default, or the intent to accelerate or of acceleration in relation to any instrument relating to the Indebtedness or the Guaranteed Obligations;

(viii) the obtaining or release of any guaranty or surety agreement, pledge, assignment or other security for the Indebtedness or the Guaranteed Obligations, or any part thereof; or

(ix)any other action at any time taken or omitted to be taken by Lender generally and any and all demands and notices of every kind in connection with this Guaranty, the other Loan Documents and any other documents or agreements evidencing, securing or relating to the Indebtedness or the Guaranteed Obligations, or any part thereof.

(b)Guarantor hereby waives any and all rights it may now or hereafter have to, and covenants and agrees that it shall not at any time, insist upon, plead or in any manner whatsoever claim or take the benefit or advantage of, any and all appraisal, valuation, stay, extension, marshaling-of-assets or redemption laws, or right of homestead or exemption, whether now or at any time hereafter in force, that may delay, prevent or otherwise affect the performance by Guarantor of its obligations under, or the enforcement by Lender of, this Guaranty. Guarantor hereby further waives any and all rights it may now or hereafter have to, and covenants and agrees that it shall not, set up or claim any defense, counterclaim, cross-claim, set-off, offset, right of recoupment or other objection of any kind to any action, suit or proceeding in law, equity or otherwise, or to any demand or claim that may be instituted or made by Lender hereunder, except for the defense of the actual timely performance of the Guaranteed Obligations hereunder.

(c)Guarantor specifically acknowledges and agrees that the waivers made by it in this Section and in the other provisions of this Guaranty are of the essence of the Loan transaction and that, but for this Guaranty and such waivers, Lender would not make the Loan to Borrower.

1.9 Waiver of Subrogation, Reimbursement and Contribution. Notwithstanding anything to the contrary contained herein, Guarantor hereby unconditionally and irrevocably waives, releases and abrogates any and all rights it may now or hereafter have under any agreement, at law or in equity (including, without limitation, any law subrogating the Guarantor to the rights of Lender), to assert any claim against or seek contribution, indemnification or any other form of reimbursement from Borrower or any other Person liable for payment of any or all of the Guaranteed Obligations for any payment made by Guarantor under or in connection with this Guaranty or otherwise.

1.10Reinstatement; Effect of Bankruptcy. Guarantor agrees that if at any time all or any part of any payment at any time received by Lender from, or on behalf of, Borrower or Guarantor under or with respect to this Guaranty is held to constitute a Preferential Payment (as defined in Section 4.4), or if Lender is required to rescind, restore or return all or part of any such payment or pay the amount thereof to another Person for any reason (including, without limitation, the insolvency, bankruptcy reorganization, receivership or other debtor relief law or any judgment, order or decision thereunder), then the Guaranteed Obligations hereunder shall, to the extent of the payment rescinded, restored or returned, be deemed to have continued in existence notwithstanding such previous receipt by Lender, and the Guaranteed Obligations hereunder shall continue to be effective or reinstated, as the case may be, as to such payment as though such previous payment to Lender had never been made.

ARTICLE IV

SUBORDINATION OF CERTAIN INDEBTEDNESS

4.1Subordination of Guarantor’s Conditional Rights. As used herein, the term “Guarantor’s Conditional Rights” shall mean any and all debts and liabilities of Borrower owed to Guarantor, whether such debts and liabilities now exist or are hereafter incurred or arise, or whether the obligations of Borrower thereon be direct, contingent, primary, secondary, several, joint and several or otherwise, and irrespective of whether such debts or liabilities be evidenced by note, contract, open account or otherwise, and irrespective of the Person or Persons in whose favor such debts or liabilities may, at their inception, have been or may hereafter be created or the manner in which they have been or may hereafter be acquired by Guarantor. The Guarantor’s Conditional Rights shall include, without limitation, all rights and claims of Guarantor for subrogation, reimbursement, exoneration, contribution or indemnification, any right to participate in any claim or remedy of Lender against Borrower or any security or

collateral which Lender now has or may hereafter acquire, whether or not such claim, remedy or right arises in equity or under contract, statute (including the Bankruptcy Code or any successor or similar statute) or common law, by any payment made hereunder or otherwise, including, without limitation, the right to take or receive from Borrower, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim or other rights, against Borrower, as a result of Guarantor’s payment of all or any portion of the Guaranteed Obligations or otherwise.

4.2Liens Subordinate; Standstill. Notwithstanding any other provision of this Guaranty to the contrary, until the payment and performance in full of the Indebtedness, Guarantor hereby agrees that (i) all Guarantor’s Conditional Rights and any and all liens, security interests, judgment liens, charges or other encumbrances upon Borrower’s assets securing payment of the Guarantor’s Conditional Rights shall be and remain, at all times, inferior and subordinate in all respects to the payment and performance in full of the Indebtedness and any and all liens, security interests, judgment liens, charges or other encumbrances upon Borrower’s assets securing payment of the Indebtedness, regardless of whether such encumbrances in favor of Guarantor or Lender presently exist or are hereafter created or attach, (ii) Guarantor shall not be entitled to, and shall not, receive or collect, directly or indirectly, from Borrower or any other Person any amount pursuant to or in satisfaction of any of the Guarantor’s Conditional Rights and (iii) Guarantor shall not, without the prior written consent of Lender, (x) exercise or enforce any creditor’s right it may have against Borrower in respect of any of the Guarantor’s Conditional Rights or (y) foreclose, repossess, sequester or otherwise take steps or institute any action or proceedings (judicial or otherwise, including, without limitation, the commencement of, or joinder in, any liquidation, bankruptcy, rearrangement, debtor’s relief or insolvency proceeding) to enforce any liens, mortgages, deeds of trust, security interests, collateral rights, judgments or other encumbrances on assets of Borrower held by Guarantor.

4.3Claims in Bankruptcy. In the event of receivership, bankruptcy, reorganization, arrangement, debtor’s relief or other insolvency proceedings involving Guarantor as debtor, Lender shall have the right and authority, either in its own name or as an attorney-in-fact for Guarantor, to prove its claim in any such proceeding and to take such other steps as may be necessary so as to establish its rights hereunder and receive directly from the receiver, trustee or other court custodian, dividends and payments which would otherwise be payable pursuant to or in satisfaction of any of the Guarantor’s Conditional Rights. Guarantor hereby assigns any and all such dividends and payments to Lender. Should Lender receive, for application against the Guaranteed Obligations, any dividend or payment which is otherwise payable to Guarantor and which, as between Borrower and Guarantor, shall constitute a credit against any of the Guarantor’s Conditional Rights, then, upon payment and performance in full of the Indebtedness and the Guaranteed Obligations, Guarantor shall become subrogated to the rights of Lender to the extent that such payments to Lender with respect to, or in satisfaction of, such Guarantor’s Conditional Rights have contributed toward the liquidation of the Guaranteed Obligations and such subrogation shall be with respect to that proportion of the Guaranteed Obligations which would have remained unpaid had Lender not received such dividends or payments upon the Guarantor’s Conditional Rights.

4.4Payments Held in Trust. In the event that, notwithstanding anything to the contrary in this Guaranty, Guarantor should receive any funds, payment, claim or distribution

which is prohibited by this Guaranty on account of any of the Guarantor’s Conditional Rights and either (i) such amount is paid to Guarantor at any time when any part of the Indebtedness or the Guaranteed Obligations shall not have been paid or performed in full or, (ii) regardless of when such amount is paid to Guarantor, any payment made by, or on behalf of, Borrower to Lender is subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid by Lender or paid over to a trustee, receiver or any other Person, whether under any bankruptcy act or otherwise (such payment, a “Preferential Payment”), then such amount paid to Guarantor shall be held in trust for the benefit of Lender and shall forthwith be paid to Lender to be credited and applied upon the Indebtedness or the Guaranteed Obligations, whether matured or unmatured, in such order as Lender, in its sole and absolute discretion, shall determine. To the extent that any of the provisions of this Article 4 shall not be enforceable, Guarantor agrees that until such time as the Indebtedness and the Guaranteed Obligations have been paid and performed in full and the period of time has expired during which any payment made by Borrower to Lender may be determined to be a Preferential Payment, all of the Guarantor’s Conditional Rights, to the extent not validly waived, shall be subordinate to Lender’s right to full payment and performance of the Indebtedness and the Guaranteed Obligations and Guarantor shall not enforce any of the Guarantor’s Conditional Rights during such period.

Notwithstanding anything to the contrary herein, Guarantor may in no event delegate or transfer its obligations under, or be released from, this Guaranty, except in accordance with the terms of the Loan Agreement and this Guaranty.

5.3Borrower. The term “Borrower” as used herein shall include any new or successor corporation, association, partnership (general or limited), limited liability company, joint venture, trust or other individual or organization formed as a result of any merger, reorganization, sale, transfer, devise, gift or bequest of or by Borrower or any interest in Borrower.

5.4Costs and Expenses. If Guarantor should breach or fail to timely perform any provision of this Guaranty, Guarantor shall promptly, upon written demand, but in any event within five (5) Business Days from the date such demand is made by Lender, pay to Lender any and all costs and expenses (including court costs and attorneys’ fees and expenses) incurred by Lender in connection with the enforcement hereof or the preservation of Lender’s rights

hereunder. The covenant contained in this Section shall survive the payment and performance of the Guaranteed Obligations.

5.5Not a Waiver; No Set-Off. The failure of any party to enforce any right or remedy hereunder, or to promptly enforce any such right or remedy, shall not constitute a waiver thereof, nor give rise to any estoppel against such party, nor excuse any other party from its obligations hereunder, nor shall a single or partial exercise thereof preclude any other future exercise, or the exercise of any other right, power, remedy or privilege. In particular, and not by way of limitation, by accepting payment after the due date of any amount payable under this Guaranty, Lender shall not be deemed to have waived any right either to require prompt payment when due of all other amounts due under this Guaranty or to declare a default for failure to effect prompt payment of any such other amount. Lender shall not be required to mitigate damages or take any other action to reduce, collect or enforce any of the Indebtedness or the Guaranteed Obligations. No set‑off, counterclaim (other than compulsory counterclaims), reduction, diminution of any obligations or any defense of any kind or nature which Guarantor has or may hereafter have against Borrower or Lender shall be available hereunder to Guarantor.

5.6PRIOR AGREEMENTS. THIS GUARANTY CONTAINS THE ENTIRE AGREEMENT OF THE PARTIES HERETO IN RESPECT OF THE GUARANTY DESCRIBED HEREIN, AND ALL PRIOR AGREEMENTS AMONG OR BETWEEN SUCH PARTIES, WHETHER ORAL OR WRITTEN, INCLUDING ANY TERM SHEETS, CONFIDENTIALITY AGREEMENTS AND COMMITMENT LETTERS, ARE SUPERSEDED BY THE TERMS OF THIS GUARANTY AS THEY RELATE TO THE GUARANTY DESCRIBED HEREIN.

5.7No Oral Change. No modification, amendment, extension, discharge, termination or waiver of any provision of this Guaranty, nor consent to any departure by Guarantor therefrom, shall in any event be effective unless the same shall be in a writing signed by Lender, and then such waiver or consent shall be effective only in the specific instance, and for the purpose, for which given. Except as otherwise expressly provided herein, no notice to, or demand on, Guarantor, shall entitle Guarantor to any other or future notice or demand in the same, similar or other circumstances.

5.8Separate Remedies. Each and all of Lender’s rights and remedies under this Guaranty and each of the other Loan Documents are intended to be distinct, separate and cumulative and no such right or remedy herein or therein mentioned is intended to be in exclusion of or a waiver of any other right or remedy available to Lender.

5.9Severability. Wherever possible, each provision of this Guaranty shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Guaranty shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Guaranty.

5.10Number and Gender. All references to sections and exhibits are to sections and exhibits in or to this Guaranty unless otherwise specified. Unless otherwise specified, the words “hereof,” “herein,” “hereby,” “hereunder” and words of similar import when

5.15GOVERNING LAW. (A) THIS GUARANTY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

(B) ANY LEGAL SUIT, ACTION OR PROCEEDING AGAINST GUARANTOR ARISING OUT OF OR RELATING TO THIS GUARANTY OR ANY OF THE OTHER LOAN DOCUMENTS (OTHER THAN ANY ACTION IN RESPECT OF THE CREATION, PERFECTION OR ENFORCEMENT OF A LIEN OR SECURITY INTEREST CREATED PURSUANT TO ANY LOAN DOCUMENTS NOT GOVERNED BY THE LAWS OF THE STATE OF NEW YORK) MAY BE INSTITUTED IN ANY FEDERAL OR STATE COURT IN NEW YORK, NEW YORK. GUARANTOR HEREBY (i) IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN SUCH A COURT AND ANY CLAIM THAT ANY SUCH PROCEEDING BROUGHT IN SUCH A COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM AND (ii) IRREVOCABLY SUBMITS TO THE JURISDICTION OF ANY SUCH COURT IN ANY SUCH SUIT, ACTION OR PROCEEDING.

5.16TRIAL BY JURY. GURANTOR, TO THE FULLEST EXTENT THAT IT MAY LAWFULLY DO SO, HEREBY AGREES NOT TO ELECT A TRIAL BY JURY OF ANY ISSUE TRIABLE OF RIGHT BY JURY, AND WAIVES ANY RIGHT TO TRIAL BY JURY FULLY TO THE EXTENT THAT ANY SUCH RIGHT SHALL NOW OR HEREAFTER EXIST WITH REGARD TO THIS GUARANTY OR ANY OF THE OTHER LOAN DOCUMENTS, OR ANY CLAIM, COUNTERCLAIM OR OTHER ACTION ARISING IN CONNECTION THEREWITH. THIS WAIVER OF RIGHT TO TRIAL BY JURY IS GIVEN KNOWINGLY AND VOLUNTARILY BY GUARANTOR AND IS INTENDED TO ENCOMPASS INDIVIDUALLY EACH INSTANCE AND EACH ISSUE AS TO WHICH THE RIGHT TO A TRIAL BY JURY WOULD OTHERWISE ACCRUE. LENDER IS HEREBY AUTHORIZED TO FILE A COPY OF THIS PARAGRAPH IN ANY PROCEEDING AS CONCLUSIVE EVIDENCE OF THIS WAIVER BY GUARANTOR.

5.17Brokers and Financial Advisors. Guarantor hereby represents that none of Borrower, Guarantor or any of their respective affiliates has dealt with any financial advisors, brokers, underwriters, placement agents, agents or finders in connection with the transactions contemplated by this Agreement and/or the other Loan Documents. Guarantor agrees to indemnify and hold Lender harmless from and against any and all claims, liabilities, costs and

expenses of any kind in any way relating to or arising from a claim by any Person that such Person acted on behalf of Borrower, Guarantor or any of their respective affiliates in connection with the transactions contemplated in this Agreement and/or the other Loan Documents. The provisions of this Section shall survive the expiration and termination of this Agreement and the repayment of the Indebtedness.

5.18Joint and Several Liability. If Guarantor is comprised of more than one Person, the obligations and liabilities of each such Person hereunder are joint and several.

5.19Release of Guarantor upon Certain Events. Subject to any provision hereof that provides for the reinstatement of the Guarantor’s obligations hereunder, the obligations of Guarantor hereunder shall terminate and be of no further force and effect upon repayment of the Loan and payment of all accrued interest and other amounts due under the Loan Agreement in full.

5.20Impairment of Subrogation Rights; Waivers of Rights Under the Anti-Deficiency Rules. Without limiting any of the other waivers and provisions set forth in this Guaranty, Guarantor hereby irrevocably and unconditionally waives all rights and defenses that Guarantor may have because the Indebtedness is secured in whole or in part by real property, including, without limitation, any rights or defenses that Guarantor may have or be entitled to assert based on or arising out of any one or more of California Code of Civil Procedure Sections 580a, 580b, 580d or 726 or California Civil Code Section 2848. This means, among other things that:

(a)Guarantor hereby agrees that upon the occurrence and during the continuation of an Event of Default, Lender may elect to foreclose either judicially or nonjudicially against any real or personal property collateral or security it holds for all or any part of the Indebtedness or the Guaranteed Obligations, or accept an assignment of any such collateral or security in-lieu of foreclosure, or compromise or adjust any part of such obligations, or make any other accommodation with Borrower or Guarantor, or exercise any other remedy against Borrower, Guarantor or any collateral or security. No such action by Lender will release or limit the liability of Guarantor to Lender, who shall remain liable under this Guaranty after any such action, even if the effect of any such action is to deprive Guarantor of the right to collect reimbursement from Borrower or any other Person for any sums paid to Lender or of its rights of subrogation, contribution or indemnity against Borrower or any other Person.

Without limiting the foregoing, Guarantor hereby waives all rights and defenses arising out of an election of remedies by Lender, even though such an election of remedies, such as nonjudicial foreclosure with respect to security for any of the Guaranteed Obligations, has impaired or destroyed any right or ability that Guarantor may have to seek reimbursement, contribution, or indemnification for any amounts paid by Guarantor under this Guaranty, by the operation of Section 580d of the California Code of Civil Procedure. Guarantor further understands and acknowledges that in the absence of this waiver such potential impairment or destruction of Guarantor’s rights, if any, may entitle Guarantor to assert a defense to this Guaranty based on California Code of Civil Procedure Section 580d as interpreted in Union Bank x. Xxxxxxx, 265 Cal. App. 2d 40, 71 Cal. Xxxx. 00 (1968), on the grounds, among others, that Lender should be estopped from pursuing Guarantor because Lender’s election to foreclose

may have impaired or destroyed such subrogation, reimbursement, contribution, or indemnification rights of Guarantor. By execution of this Guaranty, Guarantor hereby intentionally, freely, irrevocably, and unconditionally waives and relinquishes, to the extent permitted by applicable law, any such defense and agrees that (i) Guarantor will be liable under this Guaranty even though Lender has foreclosed judicially or nonjudicially against any real or personal property collateral or security for Borrower’s obligations, (ii) Guarantor will not assert any such defense in any action or proceeding which Lender may begin to enforce this Guaranty and (iii) Guarantor shall in no event be deemed to have any right, title, interest or claim under any circumstance in or to any real or personal property held by Lender or any third party following any foreclosure or assignment-in-lieu thereof of any such collateral or security.

(b)Guarantor hereby intentionally, freely, irrevocably and unconditionally waives and relinquishes all rights which may be available to Guarantor under any provision of California law or under any California judicial decision, including, without limitation, Sections 580a and 726(b) of the California Code of Civil Procedure, to limit the amount of any deficiency judgment or other judgment which may be obtained against Guarantor under this Guaranty to not more than the amount by which the unpaid Guaranteed Obligations, plus all other Indebtedness due from Borrower under the Loan Documents, exceeds the fair market value or fair value of any real or personal property securing such obligations and any other Indebtedness due from Borrower under the Loan Documents, including, without limitation, all rights to an appraisement of, judicial or other hearing on, or other determination of the value of such property. Guarantor understands and agrees that, as a result of the waiver of the foregoing rights, privileges, benefits and defenses, and without limiting the effect of the foregoing waiver, (i) Lender may have the ability to pursue Guarantor or any other guarantor for a judgment on the Guaranteed Obligations without having first foreclosed on the real or personal property collateral or security for all or any part of the Indebtedness or the Guaranteed Obligations, (ii) Lender may have the ability to xxx Guarantor or any other guarantor for a deficiency judgment on the Indebtedness or the Guaranteed Obligations after a non-judicial foreclosure sale or, regardless of any election of remedies by Lender, if the Guaranteed Obligations or any of the other Indebtedness of Borrower to Lender under the Loan Documents is considered to have been provided by a vendor to a buyer and to evidence part of the purchase price for the real or personal property collateral or security and (iii) Lender may be entitled to recover from Guarantor an amount which, when combined with the value of any real or personal property foreclosed upon by Lender (or the proceeds of the sale of which have been received by Lender) and any sums collected by Lender from Borrower or other Person, might exceed the amount of the Guaranteed Obligations plus all other Indebtedness due from Borrower under the Loan Documents.

(c)Notwithstanding the foregoing, nothing contained in this Section shall in any way be deemed to imply that California law or any other state’s law other than New York shall govern this Guaranty or any of the Loan Documents in any respect, except as may be expressly set forth therein, including with respect to the exercise of Lender’s remedies under the Loan Documents.

(d)Notwithstanding anything stated to the contrary in this Agreement, under no circumstances shall the members or partners (direct or indirect) in Guarantor have any liability for the payment and/or performance of Guarantor’s obligations hereunder.
