Mortgage Loan No. 16714

RECOURSE GUARANTY AGREEMENT

THIS RECOURSE GUARANTY AGREEMENT (this “Agreement”) is made as of November 29, 2016, by KILROY REALTY, L.P., a Delaware limited partnership (“Guarantor”), to and for the benefit of MASSACHUSETTS MUTUAL LIFE INSURANCE COMPANY, a Massachusetts corporation (“Lender”) and, to the extent applicable under Article 13 of the Loan Agreement, Administrative Agent (as defined in the Loan Agreement), and for the benefit of the other Lender Parties. As used in this Agreement, “Lender Parties” shall mean Lender, Barings Real Estate Advisers LLC, Barings Real Estate Advisers Inc., any present and future loan participants, co-lenders, loan servicers, custodians and trustees, and each of their respective directors, officers, employees, shareholders, agents, affiliates, heirs, legal representatives, successors and assigns.

R E C I T A L S:

A.    KR WMC, LLC, a Delaware limited liability company (“Borrower”), and Lender entered into that certain Loan Agreement of even date herewith (as the same may be amended or modified from time to time, the “Loan Agreement”), which Loan Agreement governs a loan (the “Loan”) in the stated principal amount of One Hundred Seventy Million and No/100 Dollars ($170,000,000.00) made by Lender to Borrower, which Loan is evidenced by that certain Promissory Note of even date herewith (as the same may be amended or modified from time to time, the “Note”).

B.    The Loan is secured in part by Borrower’s interest in and to that certain real property located in the City of Los Angeles, County of Los Angeles and State of California, and more particularly described in Exhibit A attached to the Mortgage described below (the “Premises”), as evidenced by (i) that certain Deed of Trust, Assignment of Leases and Rents, Security Agreement and Fixture Filing (as the same may be amended or modified from time to time, the “Mortgage”) with respect to the Premises, and (ii) that certain Assignment of Leases and Rents (as the same may be amended or modified from time to time, the “Assignment”) with respect to the Premises. Unless otherwise defined herein, all initially capitalized terms shall have the respective meanings ascribed to such terms in the Loan Agreement.

C.    Lender has required as a further condition to the making of the Loan to Borrower that Guarantor guaranty payment of all amounts due under Section 11.1(c) of the Loan Agreement (the “Recourse Provision”).

D.    Guarantor is financially interested in Borrower and is materially benefited by the consummation of the Loan and has agreed to unconditionally and personally guarantee payment of all amounts due Lender under the Recourse Provision.

NOW THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged and in order to induce Lender to make the Loan to Borrower, Guarantor, intending to be legally bound, hereby makes the following representations and

warranties to the Lender Parties and hereby covenants and agrees with the Lender Parties as follows:

1.Guaranty. Notwithstanding any provision contained in the Loan Agreement, the Note, Mortgage or any other Loan Document to the contrary, Guarantor absolutely, irrevocably, and unconditionally guarantees to Lender and the Lender Parties payment when due of all amounts due to Lender by Borrower pursuant to the Recourse Provision (collectively, the “Guaranteed Obligations”). This Agreement is a direct and primary obligation of Guarantor, and Guarantor’s obligations hereunder are not as a surety. This is a guarantee of timely payment and performance and not merely of collection. In the event of a default in payment of any Guaranteed Obligation when due, Lender may institute a judicial proceeding for the collection of the sums so due and unpaid, and may prosecute such proceeding to judgment or final decree, and may enforce the same against Guarantor and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of Guarantor, wherever situated.

2.    Guarantor’s Waiver of Notice. Guarantor absolutely, irrevocably and unconditionally waives (a) notice of acceptance of this Agreement, (b) notice of any payment, liability or obligation to which this Agreement may apply, (c) presentment, demand of payment, protest, notice of dishonor or nonpayment of all liabilities under this Agreement and any of the Loan Documents creating the Guaranteed Obligations, and (d) notice of any suit or other action by Lender against (including any notice from Lender to) any party liable under any Loan Document or any property which may be security for the Loan.

3.    Lender’s Rights. Lender may at any time and from time to time without the consent of, or notice to, Guarantor, without incurring any responsibility to Guarantor and without impairing or releasing any of the obligations of Guarantor hereunder, upon or without any terms or conditions and in whole or in part:

(a)    amend, modify, renew, supplement, extend (including extensions beyond the original term) or accelerate any of the Loan Documents, including without limitation, renew, alter or change the interest rate, manner, time, place or terms of payment or performance of any of the Guaranteed Obligations, or any liability incurred directly or indirectly in respect thereof, whereupon the guaranty herein made shall apply to the Guaranteed Obligations as so changed, extended, renewed or altered; provided that no amendment or modification of the Recourse Provision shall be made without the Guarantor’s prior written consent;

(b)    sell, exchange, release, surrender, and in any manner and in any order realize upon or otherwise deal with the Premises or any property at any time directly and absolutely assigned or pledged or mortgaged to secure the Loan;

(c)    consent to the transfer of the Premises or any portion thereof or any other Collateral described in the Loan Documents:

(d)    exercise or refrain from exercising any rights or remedies available to Lender under the Loan Documents or pursuant to any applicable statute against Borrower

2

or any other person (including Guarantor) or otherwise act or refrain from acting with regard to the Loan Documents, Guaranteed Obligations or this Agreement;

(e)    settle or compromise any of the Indebtedness, any security therefor or any liability (including any of those hereunder) incurred directly or indirectly in respect thereof or hereof, and/or subordinate the payment of all or any part thereof to the payment of any liability of Borrower (whether or not then due) to creditors of Borrower other than Lender and Guarantor;

(f)    release or discharge Borrower from its liability under any of the Loan Documents or release or discharge Guarantor or any endorser or any other party at any time directly or contingently, liable for the repayment of the Loan or any of Borrower’s other obligations under the Loan Documents;

(g)    apply any sums in whatever manner paid or realized to any liability or liabilities of Borrower or Guarantor to Lender regardless of what liability or liabilities of Borrower or Guarantor remain unpaid;

(h)    consent to or waive any breach of or any act, omission or default under the Loan Documents or accept partial performance of any of the obligations under this Agreement or under any of the other Loan Documents; and/or

(i)    sell, convey, participate or assign all or any part of Lender’s interest in this Agreement and the other Loan Documents.

4.    Guarantor Waiver of Defenses. Guarantor acknowledges that as a result of the waivers set forth herein, this Agreement constitutes a direct and primary obligation of Guarantor, and in connection therewith Guarantor unconditionally and irrevocably waives any defense to the enforcement of this Agreement (except as limited in this Section 4), including, without limitation:

(a)    Any defense arising by reason of Lender’s failure to provide presentments, demands for performance, notices of nonperformance, protests, notices of protest, notices of dishonor, and notices of acceptance of this Agreement;

(b)    Any defense of any statute of limitations affecting the liability of Guarantor hereunder or the liability of Borrower, or any other guarantor under the Loan Documents, or the enforcement hereof, to the extent permitted by law;

(c)    Any defense arising by reason of (i) any invalidity or unenforceability of (or any limitation of liability in) any of the Loan Documents or (ii) any defense whatsoever that Borrower may or might have to the payment of the Indebtedness or to the performance of any of the terms, provisions, covenants and agreements contained in the Loan Documents (other than any defense that Borrower is not liable under the Recourse Provision) or (iii) any manner in which Lender has exercised its rights and remedies under the Loan Documents, or (iv) cessation from any cause whatsoever;

3

(d)    Any defense based upon any disability of Borrower or Guarantor, lack of authority of the officers, directors, partners or agents acting or purporting to act on behalf of Borrower, Guarantor or any principal of Borrower or Guarantor or any defect in the formation of Borrower, Guarantor or any principal of Borrower or Guarantor as a legal entity;

(e)    Any defense based upon the application by Borrower of the proceeds of the Loan for purposes other than the purposes represented by Borrower to Lender or intended or understood by Lender or Guarantor;

(f)    Any defense based upon an election of remedies by Lender, including any election to proceed by judicial or nonjudicial foreclosure of any security, whether real property or personal property security, or by deed in lieu thereof, and whether or not every aspect of any foreclosure sale is commercially reasonable, or any election of remedies, including remedies relating to real property or personal property security, which destroys or otherwise impairs the subrogation rights of Guarantor to proceed against Borrower or any guarantor for reimbursement, or both;

(g)    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 aspect more burdensome than that of a principal;

(h)    Any defense based upon 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 any successor statute;

(i)    Any defense based upon any borrowing or any grant of a security interest under Section 364 of the Federal Bankruptcy Code;

(j)    Any defense based upon any duty of Lender to advise Guarantor of any information known to Lender regarding the financial condition of Borrower and all other circumstances affecting Borrower’s ability to perform its obligations to Lender, it being agreed that Guarantor assumes the responsibility for being and keeping informed regarding such condition or any such circumstances;

(k)    Any defense based on any right, claim or offset which Guarantor may have against Borrower; and

(l)    Any other suretyship defense that may be available to Guarantor. Without limiting the generality of the foregoing, Guarantor also waives (A) any defense based upon Lender’s election to waive its lien as to all or any security for the Loan pursuant to California Code of Civil Procedure (“CCP”) Section 726.5 or otherwise, and (B) any and all benefits which might otherwise be available to Guarantor under California Civil Code (“Civil Code”) Sections 2809, 2810, 2815, 2819, 2822, 2839, 2845 through 2850, 2899 and 3433.

5.    Additional Waivers. Guarantor understands and acknowledges that if Lender forecloses judicially or nonjudicially against any real property security for the Note, that

4

foreclosure could impair or destroy any ability that Guarantor may have to seek reimbursement, contribution or indemnification from Borrower or others based on any right Guarantor may have of subrogation, reimbursement, contribution or indemnification for any amounts paid by Guarantor under this Agreement. Guarantor further understands and acknowledges that in the absence of this provision, the potential impairment or destruction of Guarantor’s rights, if any, may entitle Guarantor to assert a defense to this Agreement based on CCP Section 580d as interpreted in Union Bank vs. Gradsky. By executing this Agreement, Guarantor freely, irrevocably and unconditionally: (1) waives and relinquishes that defense, and agrees that Guarantor will be fully liable under this Agreement, even though Lender may foreclose judicially or nonjudicially against any real property security for the Note; (2) agrees that Guarantor will not assert that defense in any action or proceeding that Lender may commence to enforce this Agreement; (3) acknowledges and agrees that the rights and defenses waived by Guarantor under this Agreement include any right or defense that Guarantor may have or be entitled to assert based upon or arising out of any one or more of the following: (A) CCP Sections 580a (which if Guarantor had not given this waiver, would otherwise limit Guarantor’s liability after any nonjudicial foreclosure sale to the difference between the obligations for which Guarantor is liable and the fair market value of the property or interests sold at such nonjudicial foreclosure sale rather than the actual proceeds of such sale), 580b and 580d (which if Guarantor had not given this waiver, would otherwise limit Lender’s right to recover a deficiency judgment with respect to purchase money obligations and after any nonjudicial foreclosure sale, respectively), or 726 (which, if Guarantor had not given this waiver, among other things, would otherwise require Lender to exhaust all of its security before a personal judgment may be obtained for a deficiency); or (B) Civil Code Section 2848; and (4) acknowledges and agrees that Lender is relying on this waiver in making the Loan, and that this waiver is a material part of the consideration that Lender is receiving for making the Loan. WITHOUT LIMITING THE FOREGOING, GUARANTOR WAIVES ALL RIGHTS AND DEFENSES THAT GUARANTOR MAY HAVE BECAUSE THE BORROWER’S DEBT AND THE GUARANTEED OBLIGATIONS ARE, OR IF ALL OF ANY PORTION OF THE BORROWER’S OBLIGATIONS ARE EVER DEEMED, SECURED BY REAL PROPERTY. THIS MEANS, AMONG OTHER THINGS:

(1)    LENDER MAY COLLECT FROM GUARANTOR WITHOUT FIRST FORECLOSING ON ANY REAL OR PERSONAL PROPERTY COLLATERAL PLEDGED BY THE BORROWER; AND

(2)    IF LENDER FORECLOSES ON ANY REAL PROPERTY COLLATERAL PLEDGED BY THE BORROWER:

a.    THE AMOUNT OF THE DEBT MAY BE REDUCED ONLY BY THE PRICE FOR WHICH THAT COLLATERAL IS SOLD AT THE FORECLOSURE SALE, EVEN IF THE COLLATERAL IS WORTH MORE THAN THE SALE PRICE; AND

b.    LENDER MAY COLLECT FROM GUARANTOR EVEN IF LENDER, BY FORECLOSING ON THE REAL PROPERTY COLLATERAL, HAS DESTROYED ANY RIGHT GUARANTOR MAY HAVE TO COLLECT FROM THE BORROWER.

5

THIS IS AN UNCONDITIONAL AND IRREVOCABLE WAIVER OF ANY RIGHTS AND DEFENSES GUARANTOR HAS BECAUSE THE BORROWER’S DEBT IS, OR BECAUSE THE BORROWER’S OBLIGATIONS MAY BE DEEMED, SECURED BY REAL PROPERTY. THESE RIGHTS AND DEFENSES INCLUDE, BUT ARE NOT LIMITED TO, ANY RIGHTS OR DEFENSES BASED UPON CCP SECTIONS 580a, 580b, 580d, OR 726.

6.    Bankruptcy.

(a)    The obligations of Guarantor hereunder shall remain in full force and effect without regard to, and shall not be affected or impaired by any bankruptcy, insolvency, reorganization, composition, adjustment, dissolution, liquidation or other like proceeding relating to Borrower, Guarantor, any other guarantor (which term shall include any other party at any time directly or contingently liable for any of Borrower’s obligations under the Loan Documents) or any affiliate of Borrower or any action taken with respect to this Agreement by any trustee or receiver, or by any court, in any such proceeding, whether or not Guarantor shall have had notice or knowledge of any of the foregoing.

(b)    Notwithstanding any modification, discharge or extension of the maturity date of the Loan, or any amendment, modification, stay or cure of Lender’s rights under the Loan Agreement, the Note, Mortgage or any other Loan Document which may occur in any bankruptcy or reorganization case or proceeding affecting Borrower, whether permanent or temporary, and whether or not assented to by Lender, Guarantor hereby agrees that Guarantor shall be obligated hereunder to pay the amounts due hereunder in accordance with the terms of this Agreement as in effect on the date hereof; provided that no amendment or modification of the Recourse Provision shall be binding on Guarantor unless Guarantor has consented to such amendment or modification.

(c)    Guarantor agrees that to the extent that Borrower makes a payment or payments to Lender with respect to any of the Guaranteed Obligations, which payment or payments or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside or required, for any of the foregoing reasons or for any other reasons, to be repaid or paid over to a custodian, trustee, receiver or any other party under any bankruptcy act, state or federal law, common law or equitable cause, then to the extent of such payment or repayment, the obligation or part thereof intended to be satisfied shall be revived and continue in full force and effect as if such payment had not been made and Guarantor shall be primarily liable for this obligation.

7.    Subrogation Waiver/Subordination.

(a)    Notwithstanding any provision to the contrary contained in the other Loan Documents or this Agreement, Guarantor hereby unconditionally and irrevocably waives until all obligations under the Loan Documents have been paid and performed in full and all applicable preference periods and fraudulent transfer periods have expired, (i) any and all rights of subrogation (whether arising under contract, 11 U.S.C. §509 or otherwise), to the claims, whether existing now or arising hereafter, Lender may have against Borrower,

6

and (ii) any and all rights of reimbursement, contribution or indemnity against Borrower or any future guarantors of any obligations under the Loan Documents) which may have heretofore arisen or may hereafter arise in connection with any guaranty or pledge or grant of any lien or security interest made in connection with any obligations under the Loan Documents. Guarantor hereby acknowledges that the waiver contained in the preceding sentence (the “Subrogation Waiver”) is given as an inducement to Lender to enter into the Loan Documents and, in consideration of Lender’s willingness to enter into the Loan Documents, Guarantor agrees not to amend or modify in any way the Subrogation Waiver without Lender’s prior written consent. If any amount shall be paid to Guarantor on account of any claim set forth at any time when all of the obligations under the Loan Documents shall not have been paid or performed in full, such amount shall be held in trust by Guarantor for Lender’s benefit, shall be segregated from the other funds of Guarantor and shall forthwith be paid over to Lender to be applied in whole or in part by Lender against such obligations, whether matured or unmatured, in accordance with Section 2.7(c) of the Loan Agreement. Nothing contained herein is intended or shall be construed to give to Guarantor any rights of subrogation or right to participate in any way in Lender’s rights, title or interest in the Loan Documents, notwithstanding any payments made by Guarantor under this Agreement, all such rights of subrogation and participation being hereby expressly waived and released until all obligations under the Loan Documents have been paid and performed in full and all applicable preference periods and fraudulent transfer periods have expired.

(b)    In the event that Guarantor shall advance or become obligated to pay any sums with respect to any obligation hereby guaranteed or in the event that for any reason whatsoever Borrower or any subsequent owner of the collateral securing the Loan is now, or shall hereafter become, indebted to Guarantor, Guarantor agrees that the amount of such sums and of such indebtedness together with all interest thereon, shall at all times be subordinate as to the lien, time of payment and in all other respects, to all sums, including principal, interest and other amounts, at any time owing to Lender under any of the Loan Documents and that Guarantor shall not be entitled to enforce or receive payment thereof until all such sums owing to Lender have been paid. Nothing herein contained is intended or shall be construed to give to Guarantor any right to participate in any way in the right, title or interest of Lender in or to the collateral securing the Loan, notwithstanding any payments made by Guarantor under this Agreement, all such rights of participation being hereby expressly waived and released.

8.    Guarantor’s Representations and Warranties. Guarantor makes the following representations and warranties which shall survive the execution and delivery of this Agreement:

(a)    Guarantor has the power and authority to execute, deliver and perform its obligations under the terms and provisions of this Agreement and has duly authorized, executed, and delivered the same.

(b)    Neither the execution and delivery of this Agreement, nor the consummation of the transactions herein contemplated, nor compliance with the terms and provisions hereof, will contravene in any material respect any provision of law, statute, rule or regulation to which Guarantor is subject or any material judgment, decree,

7

franchise, order or permit applicable to Guarantor, or will conflict or will be inconsistent with, or will result in any material breach of, any of the terms, covenants, conditions or provisions of, or constitute a material default under, or result in the creation or imposition of any lien, security interest, charge or encumbrance upon any of the property or assets of Guarantor pursuant to the terms of, any indenture, mortgage, deed of trust, agreement or other instrument to which Guarantor is a party or may be bound or subject.

(c)    No consent or approval of, or exemption by, any governmental or public body or authority is required to authorize, or is required in connection with the execution, delivery and performance of, this Agreement or of any of the instruments or agreements herein referred to, or the taking of any action hereby contemplated.

9.    Guarantor’s Relationship to Borrower. Guarantor is affiliated with Borrower, has personal knowledge of and is familiar with Borrower’s business affairs and books and records.

10.    Mortgage Priority. Nothing herein contained shall in any manner affect the lien or priority of the Mortgage securing the Loan, and upon the occurrence and during the continuance of an Event of Default, Lender may invoke any remedies it may have under this Agreement (with respect to any such Event of Default that triggers liability under the Recourse Provision) or the other Loan Documents, either concurrently or successively and the exercise of any one or more of such remedies shall not be deemed an exhaustion of such remedy or remedies or a waiver of any other remedy or remedies and shall not be deemed an election of remedies. The exercise by Lender of any such remedies shall not release, discharge or excuse Guarantor from its obligations hereunder unless and until the full amount of the Indebtedness evidenced by the Note, governed by the Loan Agreement and secured by the Mortgage has been fully paid and satisfied.

11.    Duration of Agreement. This Agreement shall remain in full force and effect until all obligations of Borrower and Guarantor under the Loan Documents have been satisfied in full and are no longer subject to disgorgement under any applicable state or federal creditor rights or bankruptcy laws. No delay on the part of Lender in exercising any options, powers or rights, or the partial or single exercise thereof, shall constitute a waiver thereof. No waiver of any rights hereunder shall be deemed to be made by Lender unless the same shall be in writing, duly signed on behalf of Lender, and each such waiver (if any) shall apply only with respect to the specific instance involved and shall in no way impair the rights of Lender or the obligations of Guarantor to Lender in any other respect at any other time. No modification or amendment of this Agreement shall be deemed to be made unless the same shall be in writing, duly signed by Lender and Guarantor. This Agreement is binding upon Guarantor, Guarantor’s heirs, personal representatives, successors or assigns, and shall inure to the benefit of the Lender Parties, including, without limitation, any other permitted holder at any time of the Loan Documents.

12.    Guarantor’s Familiarity with the Loan Documents. Guarantor acknowledges that copies of the Loan Documents have been made available to Guarantor and that Guarantor is familiar with their contents including, without limitation, the Recourse Provision. Guarantor affirmatively agrees that upon any transfer of the Premises in accordance with the provisions of the Loan Agreement, it shall not be necessary for Guarantor to reaffirm its continuing obligations under this Agreement, but Guarantor will do so upon request by Lender.
