As Representatives of the several Underwriters

Ladies and Gentlemen:

Kilroy Realty, L.P., a Delaware limited partnership (the “Operating Partnership”) and majority owned subsidiary of Kilroy Realty Corporation, a Maryland corporation (the “Company”), proposes to issue and sell to the several underwriters named in Schedule A (the “Underwriters”), $400,000,000 aggregate principal amount of the Operating Partnership’s 6.250% Senior Notes due 2036 (the “Securities”). The Securities will be issued pursuant to an Indenture dated as of March 1, 2011 (the “Base Indenture”) among the Operating Partnership, the Company and U.S. Bank Trust Company, National Association, as successor in interest to U.S. Bank National Association (the “Trustee”), as amended and supplemented by a Supplemental Indenture dated as of July 5, 2011 (the “Supplemental Indenture”) among the Operating Partnership, the Company and the Trustee (the Base Indenture, as amended and supplemented by the Supplemental Indenture, is hereinafter called the “Indenture”). BofA Securities, Inc., J.P. Morgan Securities LLC, Wells Fargo Securities, LLC, PNC Capital Markets LLC and Scotia Capital (USA) Inc. have agreed to act as representatives of the several Underwriters (in such capacity, the “Representatives”) in connection with the offering and sale of the Securities.

To the extent there are no additional Underwriters listed on Schedule A other than you, the terms Representatives and Underwriters, respectively, mutatis mutandis, as used herein shall mean you, as Underwriters and Representatives. The terms Representatives and Underwriters shall mean either the singular or the plural as the context requires.

References in this Agreement to “subsidiaries” of the Company shall include, without limitation, the Operating Partnership.

The Company and the Operating Partnership hereby confirm their respective agreements with the several Underwriters as follows:

SECTION 1. Representations and Warranties of the Company and the Operating Partnership.

The Company and the Operating Partnership, jointly and severally, represent and warrant to, and covenant with, each Underwriter as follows:

(a) The Company and the Operating Partnership have prepared and filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (File Nos. 333-267440 and 333-267440-01), and a related base prospectus dated September 15, 2022 (the “Base Prospectus”), to be used in connection with the public offering and sale of the Securities. Such registration statement, including the financial statements, exhibits and schedules thereto, at each time of effectiveness under the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (collectively, the “Securities Act”), including any information deemed to be a part thereof at the time of effectiveness pursuant to Rule 430B under the Securities Act or the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (collectively, the “Exchange Act”), is called the “Registration Statement.” Any preliminary prospectus supplement to the Base Prospectus that describes the Securities and the offering thereof and is used prior to filing of the Prospectus (as defined below), including, but not limited to, the preliminary prospectus supplement contained in the Pre-Pricing Prospectus (as defined below), is called, together with the Base Prospectus, a “preliminary prospectus.” The term “Prospectus” shall mean the final prospectus supplement dated January 9, 2024 relating to the Securities (the “Prospectus Supplement”), together with the Base Prospectus, that are first filed pursuant to Rule 424(b) after the time that this Agreement is executed and delivered by the parties hereto (the “Execution Time”). The term “Pre-Pricing Prospectus” shall mean the preliminary prospectus supplement dated January 9, 2024 relating to the Securities (the “Preliminary Prospectus Supplement”), together with the Base Prospectus, filed pursuant to Rule 424(b). Any reference herein to the Registration Statement, any preliminary prospectus (including, but not limited to, the Pre-Pricing Prospectus), the Base Prospectus, the Prospectus Supplement or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act; any reference to any amendment or supplement to the Registration Statement, any preliminary prospectus (including, but not limited to, the Pre-Pricing Prospectus) or the Prospectus shall be deemed to refer to and include any documents filed after the date of such preliminary prospectus or the Prospectus, as the case may be, or, in the case of the Registration Statement, after the date of this Agreement, under the Exchange Act and incorporated by reference in such preliminary prospectus, the Prospectus or the Registration Statement, as the case may be, and shall also be deemed to refer to and include any annual report of the Company or the Operating Partnership filed pursuant to Section 13(a) or 15(d) of the Exchange Act after

2

the effective date of the Registration Statement that is incorporated by reference in the Registration Statement. As used herein, the term “Issuer Free Writing Prospectus” means any “issuer free writing prospectus,” as defined in Rule 433 under the Securities Act (“Rule 433”) relating to the offering of the Securities that (i) is required to be filed with the Commission by the Company, (ii) is a road show that is a written communication within the meaning of Rule 433(d)(8)(i), whether or not required to be filed with the Commission or (iii) is exempt from filing pursuant to Rule 433(d)(5)(i) because it contains a description of the Securities or of the offering that does not reflect the final terms, in each case in the form filed or required to be filed with the Commission or, if not required to be filed, in the form required to be retained in the Company’s records pursuant to Rule 433(g).

(b) Compliance with Registration Requirements. The Registration Statement has become effective under the Securities Act and there are no outstanding requests of the Commission for additional or supplemental information. No stop order suspending the effectiveness of the Registration Statement is in effect, the Commission has not issued any order or notice preventing or suspending the use of the Registration Statement, any preliminary prospectus or the Prospectus and no proceedings for such purpose have been instituted or are pending or, to the knowledge of the Company or the Operating Partnership, are contemplated or threatened by the Commission.

Each preliminary prospectus and the Prospectus when filed complied in all material respects with the Securities Act and the rules thereunder. Each of the Registration Statement and any post-effective amendment thereto, at each time of effectiveness (including, but not limited to, each “new effective date” with respect to the Underwriters pursuant to Rule 430B(f)(2) of the Securities Act) and at the date hereof, complied and will comply in all material respects with the Securities Act and the Trust Indenture Act of 1939, as amended, and the rules and regulations of the Commission promulgated thereunder (collectively, the “Trust Indenture Act”), and did not and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading. The Prospectus, as amended or supplemented, as of its date, at the date hereof, at the time of any filing pursuant to Rule 424(b) and at the Closing Date (as defined herein), did not and will not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The representations and warranties set forth in the two immediately preceding sentences do not apply to statements in or omissions from the Registration Statement or any post-effective amendment thereto, or the Prospectus or any amendments or supplements thereto, made in reliance upon and in conformity with information furnished to the Company and the Operating Partnership in writing by any Underwriter through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriter through the Representatives consists of the information described as such in Section 8(b) hereof. There is no contract or other document required to be described in the Prospectus or to be filed as an exhibit to the Registration Statement that has not been described or filed as required.

3

(c) Documents Incorporated by Reference. The documents incorporated by reference in each of the Disclosure Package (as defined below) and the Prospectus, when they became effective or were filed with the Commission, as the case may be, complied in all material respects with the requirements of the Securities Act or the Exchange Act, as applicable, and the rules and regulations of the Commission thereunder. Any documents to be filed and incorporated by reference in the Prospectus or any further amendment or supplement to any documents previously filed and incorporated by reference, when such documents become effective or are filed with the Commission, as the case may be, will conform in all material respects to the requirements of the Securities Act or the Exchange Act, as applicable, and the rules and regulations of the Commission thereunder. None of such documents did or will, as the case may be, as of its respective filing or effective date, as the case may be, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(d) Disclosure Package. The term “Disclosure Package” shall mean (i) the Pre-Pricing Prospectus, (ii) the Issuer Free Writing Prospectus or Issuer Free Writing Prospectuses, if any, identified in Schedule B hereto, and (iii) any other free writing prospectus that the parties hereto shall hereafter expressly agree in writing to treat as part of the Disclosure Package. As of 3:45 p.m. (Eastern time) on the date of this Agreement (the “Applicable Time”), neither (x) the Disclosure Package nor (y) any individual Issuer Free Writing Prospectus that is not part of the Disclosure Package, when considered together with the Disclosure Package, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from the Disclosure Package or any Issuer Free Writing Prospectus that is not part of the Disclosure Package made in reliance upon and in conformity with information furnished to the Company and the Operating Partnership in writing by any Underwriter through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriter through the Representatives consists of the information described as such in Section 8(b) hereof.

(e) Company is Well-Known Seasoned Issuer. (i) At the time of filing the Registration Statement, (ii) at the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3) of the Securities Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Section 13 or 15(d) of the Exchange Act or form of prospectus), (iii) at the time the Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c) of the Securities Act) made any offer relating to the Securities in reliance on the exemption of Rule 163 of the Securities Act, and (iv) at the Execution Time of this Agreement (with such date being used as the determination date for purposes of this clause (iv)), the Company was and is a “well-known seasoned issuer” as defined in Rule 405 of the Securities Act. The Registration Statement is an “automatic shelf registration statement,” as defined in Rule 405 of the Securities Act, and neither the Company nor the Operating Partnership has received from the Commission any notice pursuant to Rule 401(g)(2) of the Securities Act objecting to use of the automatic shelf registration statement form.

4

(f) Issuer Free Writing Prospectuses. Each Issuer Free Writing Prospectus, as of its issue date did not and, unless superseded by a subsequent Issuer Free Writing Prospectus, as of the date of this Agreement, does not include any information that conflicted or conflicts with the information contained in the Registration Statement. If at any time following the date of this Agreement, there occurs an event or development as a result of which such Issuer Free Writing Prospectus would conflict with the information contained in the Registration Statement, the Company and the Operating Partnership will promptly notify the Representatives and will promptly amend or supplement, at their own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict. The first two sentences of this paragraph do not apply to statements in or omissions from any Issuer Free Writing Prospectus made in reliance upon and in conformity with written information furnished to the Company and the Operating Partnership by any Underwriter through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter through the Representatives consists of the information described as such in Section 8(b) hereof. The information in Schedule C hereto has been included in an Issuer Free Writing Prospectus identified in Schedule B hereto.

All of the issued and outstanding shares of capital stock of each subsidiary of the Company that is a corporation, all of the issued and outstanding limited and general partnership interests of each subsidiary of the Company that is a limited partnership and all of the issued and outstanding limited liability company interests (or other similar interests) of each subsidiary of the Company that is a limited liability company have been duly authorized and validly issued, are fully paid and (except for general partnership and limited liability company membership interests) nonassessable and, to the extent such shares or interests are owned by the Company, directly or through subsidiaries, such shares and interests are owned free and clear of any Lien (as defined herein).

The authorized Preferred Stock (as defined below) of the Company is as set forth under the caption “Description of Capital Stock – Preferred Stock” in the Disclosure Package and the Prospectus. The authorized, issued and outstanding Common Stock of the Company as of September 30, 2023 was as set forth in the line items appearing under the caption “Stockholders’ Equity” in the Company’s unaudited consolidated balance sheet as of September 30, 2023 appearing in the Company’s and the Operating Partnership’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2023, and, since September 30, 2023, the Company has not issued, repurchased or cancelled any capital stock (other than subsequent issuances or share repurchases or cancellations, if any, (i) described in the Disclosure Package and the Prospectus, (ii) pursuant to any underwritten public offerings, at-the-market offering programs, or any employee benefit plans or dividend reinvestment plans described in the Disclosure Package and the Prospectus, (iii) upon exercise of outstanding options issued pursuant to employee benefit plans described in the Disclosure Package and the Prospectus or (iv) upon the redemption of Common Units pursuant to the Seventh Amended and Restated Agreement of Limited Partnership of the Operating Partnership and any amendments or supplements thereto whether before or after the date of this Agreement (as so amended and supplemented, if applicable, the “Partnership Agreement”)). The Common Stock conforms in all material respects to the description thereof contained in the Disclosure Package and the Prospectus. All of the issued and outstanding shares of Common Stock have been duly authorized and validly issued, are fully paid and nonassessable and have been issued in compliance with federal and state securities laws. None of the outstanding shares of Common Stock were issued in violation of any preemptive rights, rights of first refusal or other similar rights to subscribe for or purchase securities of the Company. The Company has duly reserved a sufficient number of shares of Common Stock for issuance upon exchange of the common units of partnership interest of the Operating Partnership. The Company has no issued and outstanding shares of preferred stock, par value $0.01 per share (“Preferred Stock”). All of the Company’s unissued Preferred Stock has been duly authorized. There are no authorized or outstanding options, warrants, preemptive rights, rights of first refusal or other rights to purchase, or equity or debt securities convertible into or exchangeable or exercisable for, any capital stock of the Company or any of its subsidiaries other than such as may have been issued under employee benefit plans that are accurately described in the Disclosure Package and the Prospectus or otherwise as accurately described in the Disclosure Package and the Prospectus. The description of the Company’s stock option, stock bonus and other stock plans or arrangements, and the options or other rights granted thereunder incorporated by reference in the Disclosure Package and the Prospectus accurately and fairly presents the terms and conditions of such plans, arrangements, options and rights in all material respects.

(u) Non-Contravention of Existing Instruments; No Further Authorizations or Approvals Required. Neither the Company nor any of its subsidiaries is (i) in violation or in default (or, with the giving of notice or lapse of time, would be in default) (“Default”) under its charter or bylaws, limited partnership agreement, limited liability company agreement or similar organizational documents, as the case may be, (ii) in Default under any indenture, mortgage, loan or credit agreement, deed of trust, note, contract, franchise, lease or other agreement, obligation, condition, covenant or instrument to which the Company or any such subsidiary is a party or by which it may be bound, or to which any of the property or assets of the Company or any of its subsidiaries is subject (each, an “Existing Instrument”) or (iii) in violation of any statute, law, rule, regulation, judgment, order or decree of any court, regulatory body, administrative agency,

9

governmental body, arbitrator or other authority having jurisdiction over the Company or any such subsidiary or any of its properties, as applicable, except with respect to clauses (ii) and (iii) only, for such Defaults as would not, individually or in the aggregate, have a Material Adverse Effect. The Company’s and the Operating Partnership’s execution, delivery and performance of the Transaction Documents and the consummation of the transactions contemplated hereby and thereby, by the Disclosure Package and by the Prospectus (i) have been duly authorized by all necessary corporate and partnership action and will not result in any Default under the charter or bylaws or other organizational documents (including, without limitation, the Partnership Agreement) of the Company or any subsidiary of the Company, (ii) will not conflict with or constitute a breach of, or Default under, or result in the creation or imposition of any Lien upon any property or assets of the Company, the Operating Partnership or any of their respective subsidiaries pursuant to, or require the consent of any other party to, any Existing Instrument, and (iii) will not result in any violation of any statute, law, rule, regulation, judgment, order or decree applicable to the Company, the Operating Partnership or any of their respective subsidiaries of any court, regulatory body, administrative agency, governmental body, arbitrator or other authority having jurisdiction over the Company, the Operating Partnership or any of their respective subsidiaries or any of its or their properties, except with respect to clauses (ii) and (iii) only, for such conflicts, breaches, Defaults, Liens, consents or violations as would not, individually or in the aggregate, have a Material Adverse Effect or adversely affect the consummation of the transactions contemplated by the Transaction Documents. No consent, approval, authorization or other order of, or registration or filing with, any court or other governmental or regulatory authority or agency is required for the Company’s and the Operating Partnership’s execution, delivery and performance of the Transaction Documents and the consummation of the transactions contemplated hereby and thereby, except such as have been obtained or made by the Company or the Operating Partnership and are in full force and effect under the Securities Act, the Exchange Act or the Trust Indenture Act, as the case may be, and such as may be required under applicable state securities or blue sky laws and from the Financial Industry Regulatory Authority, Inc. (“FINRA”).

10

Except as would not reasonably be expected to have a Material Adverse Effect, the Company and its subsidiaries own, possess, license or have other rights to use, on reasonable terms, all patents, patent applications, trade and service marks, trade and service mark registrations, trade names, copyrights, licenses, inventions, trade secrets, technology, know-how and other intellectual property (collectively, the “Intellectual Property”) necessary for the conduct of the Company’s and its subsidiaries’ business as now conducted or as proposed in the Disclosure Package and the Prospectus to be conducted.

(y) All Necessary Permits, etc. The Company and each of its subsidiaries possess such valid and current licenses, certificates, authorizations or permits (collectively, the “Permits”) issued by the appropriate state, federal or foreign regulatory agencies or bodies necessary to conduct their respective businesses except for such Permits where the failure to so possess would not, individually or in the aggregate, have a Material Adverse Effect, and neither the Company nor any of its subsidiaries has received any notice of proceedings relating to the revocation or modification of, or non-compliance with, any such Permit which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, could reasonably be expected to have a Material Adverse Effect.

SECTION 8. Indemnification.

(a) Indemnification of the Underwriters. The Company and the Operating Partnership, jointly and severally, agree to indemnify and hold harmless each Underwriter, its affiliates, directors, officers, employees and agents, and each person, if any, who controls any Underwriter within the meaning of the Securities Act or the Exchange Act, from and against any loss, claim, damage, liability or expense, as incurred, to which such Underwriter or such affiliate, director, officer, employee, agent or controlling person may become subject, insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any amendment thereto, including any information deemed to be a part thereof pursuant to Rule 430B under the Securities Act, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading; or (ii) any untrue statement or alleged untrue statement of a material fact contained (A) in any Issuer Free Writing Prospectus, any preliminary prospectus, the Disclosure Package or the Prospectus (or any amendment or supplement thereto) or (B) in any information provided to investors by, or with the approval of, the Company in connection with any offering of the Securities (“Marketing Information”), including any roadshow or investor presentations made to investors by the Company (whether in person or electronically), or the omission or alleged omission in any Issuer Free Writing Prospectus, any preliminary prospectus, the Disclosure Package or the Prospectus (or any amendment or supplement thereto) or in any Marketing Information of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, and to reimburse each Underwriter, its affiliates, officers, directors, employees, agents and each such controlling person for any and all documented and reasonably incurred expenses (including the fees and disbursements of counsel chosen by the Representatives) as such expenses are incurred by such Underwriter or its affiliates, officers, directors, employees, agents or such controlling persons in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the foregoing indemnity agreement shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company and the Operating Partnership by any Underwriter through the Representatives expressly for use in the Registration Statement, any Issuer Free Writing Prospectus, any preliminary prospectus, the Disclosure Package or the Prospectus (or any amendment or supplement thereto) as set forth in Section 8(b) of this Agreement. The Company and the Operating Partnership hereby acknowledge that the only information the Underwriters have furnished to the Company and the Operating Partnership for the uses set forth in the preceding sentence are the statements set forth in the penultimate sentence of Section 8(b). The indemnity agreement set forth in this Section 8(a) shall be in addition to any liabilities that the Company and the Operating Partnership may otherwise have.

27

(b) Indemnification of the Company, the Operating Partnership and its General Partner. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, the Operating Partnership, the general partner of the Operating Partnership (the “General Partner”), each of the Company’s directors, each of the Company’s officers who signed the Registration Statement on behalf of the Company or the General Partner and each person, if any, who controls the Company or the Operating Partnership within the meaning of the Securities Act or the Exchange Act, from and against any loss, claim, damage, liability or expense, as incurred, to which the Company, the Operating Partnership, the General Partner, any such director or officer or any such controlling person may become subject, insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any Issuer Free Writing Prospectus, any preliminary prospectus, the Disclosure Package or the Prospectus (or any amendment or supplement thereto), or arises out of or is based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, and only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, any Issuer Free Writing Prospectus, any preliminary prospectus, the Disclosure Package or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company and the Operating Partnership by such Underwriter through the Representatives expressly for use therein; and to reimburse the Company, the Operating Partnership, the General Partner, any such director or officer or any such controlling person for any and all documented and reasonably incurred expenses (including the fees and disbursements of counsel chosen by the Company) as such expenses are incurred by the Company, the Operating Partnership, the General Partner, any such director or officer or any such controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. The Company and the Operating Partnership hereby acknowledge that the only information that the Underwriters have furnished to the Company and the Operating Partnership expressly for use in the Registration Statement, any Issuer Free Writing Prospectus, any preliminary prospectus, the Disclosure Package or the Prospectus (or any amendment or supplement thereto) are the statements set forth in (a) the first and second sentences under the subcaption “Underwriting (Conflicts of Interest)—Discounts” in the Pre-Pricing Prospectus and the Prospectus concerning the public offering price, concession and reallowance, (b) the third sentence under the subcaption “Underwriting (Conflicts of Interest)—New Issue of Notes” in the Pre-Pricing Prospectus and the Prospectus concerning the Underwriters’ intention to make a market in the Securities and (c) the first three sentences under the subcaption “Underwriting (Conflicts of Interest)—Price Stabilization and Short Positions” in the Pre-Pricing Prospectus and the Prospectus, but only insofar as concerns the Representatives and the Underwriters, regarding stabilization, overallotments and short positions. The indemnity agreement set forth in this Section 8(b) shall be in addition to any liabilities that each Underwriter may otherwise have.

(c) Notifications and Other Indemnification Procedures. Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof, but the failure to so notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and

28

such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party under this Agreement other than the indemnification obligation provided in paragraph (a) or (b) above. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (other than local counsel), reasonably approved by the Company and the Operating Partnership, in the case of Section 8(a) or by the Representatives, in the case of Section 8(b), representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party.

(d) Settlements. The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, which shall not be withheld unreasonably, but if settled with such consent or if there is a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have provided the indemnifying party with the proposed terms of settlement and shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by Section 8(c) hereof, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (x) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (y) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

29

SECTION 9. Contribution. If the indemnification provided for in Section 8 is for any reason unavailable to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Operating Partnership, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Operating Partnership, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions or inaccuracies in the representations and warranties herein which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Operating Partnership, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Operating Partnership, and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth on the front cover page of the Prospectus, bear to the aggregate initial public offering price of the Securities as set forth on such cover. The relative fault of the Company and the Operating Partnership, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Operating Partnership, on the one hand, or the Underwriters, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 8(c), any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim.

The Company, the Operating Partnership and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in this Section 9.

30

Notwithstanding the provisions of this Section 9, no Underwriter shall be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Securities exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of the untrue statements or omissions or alleged untrue statements or omissions which resulted in such losses, claims, damages, liabilities or expenses. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The obligations of the Company and the Operating Partnership to contribute pursuant to this Section 9 are joint and several. The Underwriters’ obligations to contribute pursuant to this Section 9 are several, and not joint, in proportion to their respective underwriting commitments as set forth opposite their names in Schedule A. For purposes of this Section 9, each affiliate, director, officer, employee and agent of an Underwriter and each person, if any, who controls an Underwriter within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as such Underwriter, and each director of the Company and the Operating Partnership, each officer of the Company and the Operating Partnership who signed the Registration Statement, the General Partner and each person, if any, who controls the Company or the Operating Partnership within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as the Company or the Operating Partnership, as the case may be.

SECTION 10. Default of One or More of the Several Underwriters. If, on the Closing Date, any one or more of the several Underwriters shall fail or refuse to purchase Securities that it or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase does not exceed 10% of the aggregate principal amount of all of the Securities to be purchased on such date, the other Underwriters shall be obligated, severally, in the proportions that the principal amount of Securities set forth opposite their respective names on Schedule A bears to the aggregate principal amount of Securities set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as may be specified by the Representatives with the consent of the non-defaulting Underwriters, to purchase the principal amount of Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date. If, on the Closing Date, any one or more of the Underwriters shall fail or refuse to purchase Securities that it or they have agreed to purchase hereunder on such date and the aggregate principal amount of Securities with respect to which such default occurs exceeds 10% of the aggregate principal amount of Securities to be purchased on such date, and arrangements satisfactory to the Representatives, the Company and the Operating Partnership for the purchase of such Securities are not made within 48 hours after such default, this Agreement shall terminate without liability of any party to any other party, except that the provisions of Section 4, Section 8 and Section 9 shall at all times be effective and shall survive such termination. In any such case either the Representatives or the Company and the Operating Partnership shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, to the Registration Statement and the Prospectus or any other documents or arrangements may be effected.

As used in this Agreement, the term “Underwriter” shall be deemed to include any person substituted for a defaulting Underwriter under this Section 10. Any action taken under this Section 10 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

31

SECTION 11. Termination of this Agreement. Prior to the payment for, and delivery to the Underwriters of, the Securities on the Closing Date this Agreement may be terminated by the Representatives by notice given to the Company and the Operating Partnership if at any time (i) trading or quotation in any securities issued or guaranteed by the Company or the Operating Partnership shall have been suspended or limited by the Commission or by the New York Stock Exchange; (ii) trading in securities generally on the New York Stock Exchange shall have been suspended or limited, or minimum or maximum prices shall have been generally established on any of such stock exchanges by the Commission or FINRA; (iii) a general banking moratorium shall have been declared by federal or New York authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States has occurred; or (iv) there shall have occurred any outbreak or escalation of national or international hostilities or any crisis or calamity, or any change in the United States or international financial markets, or any substantial change or development involving a prospective substantial change in United States’ or international political, financial or economic conditions, as in the judgment of the Representatives is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities in the manner and on the terms described in the Prospectus or to enforce contracts for the sale of securities. Except as provided in Section 6 hereof, any termination pursuant to this Section 11 shall be without liability on the part of (a) the Company or the Operating Partnership to any Underwriter or (b) any Underwriter to the Company or the Operating Partnership.

SECTION 12. No Advisory or Fiduciary Responsibility. The Company and the Operating Partnership acknowledge and agree, jointly and severally, that: (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the public offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company and the Operating Partnership, on the one hand, and the several Underwriters, on the other hand, and does not constitute a recommendation, investment advice, or solicitation of any action by the Underwriters, and the Company and the Operating Partnership are capable of evaluating and understanding and understand and accept the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with each transaction contemplated hereby and the process leading to such transaction each Underwriter is and has been acting solely as a principal and is not the financial advisor, agent or fiduciary of the Company, the Operating Partnership or their respective affiliates, stockholders, creditors, limited or general partners, or employees or any other party; (iii) no Underwriter has assumed or will assume an advisory, agency or fiduciary responsibility in favor of the Company or the Operating Partnership with respect to any of the transactions contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company or the Operating Partnership on other matters) and no Underwriter has any obligation to the Company or the Operating Partnership with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement; (iv) the several Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and the Operating Partnership and that the several Underwriters have no obligation to disclose any of such interests by virtue of any advisory, agency or fiduciary relationship; (v) the Underwriters have not provided any legal, accounting, regulatory, investment or tax advice with respect to the offering contemplated hereby and the Company and the Operating Partnership have consulted their own legal, accounting, regulatory and tax advisors to the extent they deemed appropriate; and (vi) none of the activities of the Underwriters in connection with the transactions contemplated herein constitutes a recommendation, investment advice or solicitation of any action by the Underwriters with respect to any entity or natural person.

32

This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company, the Operating Partnership and the several Underwriters, or any of them, with respect to the subject matter hereof.

ANNEX I

Capitalized terms used in this Annex I and not otherwise defined herein have the same definitions as in the Indenture referred to in the Officers’ Certificate of which this Annex I constitutes a part.

I-1

Prior to October 15, 2035 (three months prior to the maturity date of the Securities of such series) (the “Par Call Date”), the Company may redeem the Securities of such series at its option, in whole or in part, at any time and from time to time, at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

plus, in either case, accrued and unpaid Interest thereon to the Redemption Date.

On or after the Par Call Date, the Company may redeem the Securities of such series, in whole or in part, at any time and from time to time, at a Redemption Price equal to 100% of the principal amount of the Securities of such series being redeemed plus accrued and unpaid Interest thereon to the Redemption Date.

I-2

The Company’s actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error.

Notwithstanding the foregoing, installments of Interest that are due and payable on any Interest Payment Date falling on or prior to a Redemption Date with respect to the Securities of such series will be payable to the Persons who were the Holders of the Securities of such series (or one or more Predecessor Securities), registered as such at the close of business on the relevant Regular Record Dates according to their terms and the provisions of the Indenture. Written notice of redemption must be given to Holders of the Securities of such series (or portions thereof) to be redeemed not less than 10 nor more than 60 days prior to the applicable Redemption Date.

If less than all of the Securities of such series are to be redeemed, the particular Securities of such series to be redeemed shall be selected in the manner provided in Section 1103 of the Indenture in minimum principal amounts of $2,000 and integral multiples of $1,000 in principal amount in excess thereof; provided that, in the case of any Security of such series redeemed in part, the unredeemed portion thereof shall be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

Notwithstanding the foregoing, the Company shall not redeem the Securities of such series on any date if the principal amount of the Securities of such series has been accelerated, and such acceleration has not been rescinded or cured on or prior to the applicable Redemption Date as provided in the Indenture.

The redemption of the Securities of such series shall otherwise be made as provided in the Indenture, including Article Eleven thereof.

Certain Definitions

“Treasury Rate” means, with respect to any Redemption Date, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate shall be determined by Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the date the notice of redemption is given based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields—one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life—and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

I-3

If on the third business day preceding the date the notice of redemption is given H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding the date the notice of redemption is given of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

To the addressees set forth above:

We have acted as special counsel to Kilroy Realty, L.P., a Delaware limited partnership (the “Company”), and Kilroy Realty Corporation, a Maryland corporation (the “Guarantor”), in connection with the issuance of $400,000,000 aggregate principal amount of the Company’s 6.250% Senior Notes due 2036 (the “Notes”) and the guarantees of the Notes (the “Guarantees”) by the Guarantor pursuant to an indenture dated March 1, 2011 (the “Base Indenture”), by and among the Company, the Guarantor and U.S. Bank Trust Company, National Association (as successor in interest to U.S. Bank National Association), as trustee (the “Trustee”), as amended and supplemented by a supplemental indenture dated July 5, 2011 (the “Supplemental Indenture”; the Base Indenture, as amended and supplemented by the Supplemental Indenture, is hereinafter called the “Indenture”), among the Company, the Guarantor and the Trustee, and an officers’ certificate dated the date hereof, establishing the form and terms of the Notes and Guarantees pursuant to the Indenture, and pursuant to: (i) a registration statement on Form S-3 under the Securities Act of 1933, as amended (the “Act”), filed with the Securities and Exchange Commission (the “Commission”) on September 15, 2022 (Registration Nos. 333-267440 and 333-267440 -01) (as so filed, the “Registration Statement”); (ii) a base prospectus dated September 15, 2022 (the “Base Prospectus”); (iii) a prospectus supplement dated January 9, 2024 filed with the Commission pursuant to Rule 424(b) under the Act (the “Prospectus Supplement” and, together with the Base Prospectus, the “Prospectus”); and (iv) an underwriting agreement dated January 9, 2024 by and among the Company, the Guarantor and BofA Securities, Inc., J.P.

As such counsel, we have examined such matters of fact and questions of law as we have considered appropriate for purposes of this letter. With your consent, we have relied upon certificates and other assurances of officers of the Company, the Guarantor and others as to factual matters without having independently verified such factual matters. We are opining herein as to the internal laws of the State of New York and the Delaware Revised Uniform Limited Partnership Act (“DRULPA”), and we express no opinion with respect to the applicability thereto, or the effect thereon, of the laws of any other jurisdiction or, in the case of Delaware, any other laws, or as to any matters of municipal law or the laws of any local agencies within any state. Various matters concerning laws of the State of Maryland are addressed in the opinion of Ballard Spahr LLP, separately provided to you. We express no opinion with respect to those matters, and to the extent elements of those opinions are necessary to the conclusions expressed herein, we have, with your consent, assumed such matters.

Subject to the foregoing and the other matters set forth herein, it is our opinion that, as of the date hereof:

1. Assuming due authorization and execution by the Guarantor in its capacity as the sole general partner of the Company, when issued and authenticated in accordance with the terms of the Indenture, and delivered against payment therefor in the circumstances contemplated by the Underwriting Agreement, the Notes will be legally valid and binding obligations of the Company, enforceable against the Company in accordance with their terms.

2. Assuming due authorization and execution by the Guarantor on its own behalf, when issued in connection with the execution, delivery and authentication of the Notes in accordance with the terms of the Indenture, the Guarantees will be legally valid and binding obligations of the Guarantor, enforceable against the Guarantor in accordance with their terms.

Our opinions are subject to: (i) the effects of bankruptcy, insolvency, reorganization, voidable preference, fraudulent transfer, moratorium or other similar laws relating to or affecting the rights and remedies of creditors; (ii) the effects of general principles of equity, whether considered in a proceeding in equity or at law (including the possible unavailability of specific performance or injunctive relief), concepts of materiality, reasonableness, good faith and fair dealing, and the discretion of the court before which a proceeding is brought; (iii) the invalidity under certain circumstances under law or court decisions of provisions providing for the indemnification or exculpation of, or contribution to, a party with respect to a liability where such indemnification, exculpation or contribution is contrary to public policy; and (iv) we express no opinion with respect to (a) any provision for liquidated damages, default interest, late charges, monetary penalties, make-whole premiums or other economic remedies to the extent such provisions are deemed to constitute a penalty, (b) consents to, or restrictions upon, governing law, jurisdiction, venue, service of process, arbitration, remedies, or judicial relief, (c) the waiver of rights or defenses contained in Section 1011 of the Indenture, (d) any provision requiring the payment of attorneys’ fees, where such payment is contrary to law or public policy, (e) any provision permitting, upon acceleration of any indebtedness (including the Notes) collection of that portion of the stated principal amount thereof which might be determined to constitute unearned interest thereon, (f) provisions purporting to make a guarantor primarily liable rather than as a surety and provisions purporting to waive modifications of any guaranteed obligation to the extent such modification constitutes a novation, (g) advance waivers of claims, defenses, rights granted by law, or notice, opportunity for hearing, evidentiary requirements, statutes of limitation, trial by jury or at law, or other procedural rights, (h) waivers of broadly or vaguely stated rights, (i) provisions prohibiting, restricting, or requiring consent to assignment or transfer of any right or property, (j) provisions for exclusivity, election or cumulation of rights or remedies, (k) provisions authorizing or validating conclusive or discretionary determinations including, without limitation, with respect to option value determinations and (l) the severability, if invalid, of provisions to the foregoing effect.

With your consent, we have assumed for purposes of this opinion that (i) each of the parties to the Indenture, the Notes and the Guarantees (collectively, the “Documents”) other than the Company is (a) duly organized, validly existing and in good standing under the laws of its jurisdiction of organization, (b) has the requisite power and authority to execute and deliver and to perform its obligations under each of the Documents to which it is a party and (c) has duly authorized, executed and delivered each such Document, (ii) with respect to each of the parties to the Documents other than the Company and the Guarantor, each Document to which it is a party constitutes its legally valid and binding agreement, enforceable against it in accordance with its terms, (iii) the Notes have been duly authorized for issuance by all necessary corporate action by the Guarantor in its capacity as the general partner of the Company, (iv) the Indenture has been duly authorized by all necessary corporate action by the Guarantor on its own behalf and in its capacity as the general partner of the Company and has been duly executed and delivered by the Guarantor on its own behalf and in its capacity as the general partner of the Company, (v) the Guarantees have been duly authorized by all necessary corporate actions of the Guarantor and have been duly executed and delivered by the Guarantor, (vi) the status of the Documents as legally valid and binding obligations of the parties is not affected by any (a) breaches of, or defaults under, agreements or instruments, (b) violations of statutes, rules, regulations or court or governmental orders, or (c) failures to obtain required consents, approvals or authorizations from, or make required registrations, declarations or filings with, governmental authorities, and (vii) the Trustee is in compliance, generally and with respect to acting as Trustee under the Indenture, with all applicable laws and regulation.

This opinion is for your benefit in connection with the Registration Statement and may be relied upon by you and by persons entitled to rely upon it pursuant to the applicable provisions of the Act. We consent to your filing this opinion as an exhibit to the Company’s Form 8-K dated January 12, 2024 and to the reference to our firm contained in the Prospectus under the heading “Legal Matters.” In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Commission thereunder.
