Form of Indemnification Agreement

 Exhibit 10.89 
 INDEMNIFICATION AGREEMENT 
 This
INDEMNIFICATION AGREEMENT is made this          day of                     ,
20     (“Agreement”), by and between KILROY REALTY CORPORATION, a Maryland corporation (the “Company”), and
                                         
                    (“Indemnitee”). 
 RECITALS 
 WHEREAS, at the request of the Company, the Indemnitee currently
serves as a director and/or officer of the Company and/or one or more affiliates of the Company and renders valuable services to, or for the benefit of, the Company; and 
 WHEREAS, the Company desires to attract and retain the services of highly qualified individuals, such as Indemnitee, to serve as directors and officers of the Company and its affiliates; and 

WHEREAS, both the Company and the Indemnitee recognize the increased legal risks and potential liabilities to which directors and
officers of corporations are subject in connection with their positions and that liability insurance for directors and officers and statutory indemnification provisions may be inadequate to provide proper protection to individuals requested to serve
as directors and officers of the Company; and 
 WHEREAS, in order to induce Indemnitee to continue to provide services to the
Company as an officer and/or director, the Company desires to provide for the indemnification of, and the advancement of expenses to, Indemnitee as set forth in this Agreement. 
 NOW THEREFORE, in consideration of the foregoing premises, the covenants and agreements contained herein, and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the Company and the Indemnitee do hereby agree as follows: 
 1. Certain Definitions. For purposes of this Agreement the following terms should have the following meanings: 
 (a) “Board of Directors” means the Board of Directors of the Company. 
 (b) “Bylaws” mean the bylaws of the Company, as the same may be amended from time to time. 

 (c) “Change in Control” means the following:

Commission) whereby any “person” or related “group” of “persons” (as such terms are used in Sections 13(d) and 14(d)(2) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) (other than the
Company, any of its subsidiaries, an employee benefit plan maintained by the Company or any of its subsidiaries or a “person” that, prior to such transaction, directly or indirectly controls, is controlled by, or is under common control
with, the Company) directly or indirectly acquires beneficial ownership (within the meaning of Rule 13d-3 under the Exchange Act) of securities of the Company and immediately after such acquisition possesses more than 50% of the total combined
voting power of the Company’s securities outstanding immediately after such acquisition; or 

  

	 	ii.	During any period of two consecutive years, individuals who, at the beginning of such period, constitute the Board of Directors together with any new director(s) (other
than a director designated by a person who shall have entered into an agreement with the Company to effect a transaction described in clause (i) hereof or clause (iii) hereof) whose election by the Board of Directors or nomination for
election by the Company’s stockholders was approved by a vote of at least two-thirds of the directors then still in office who either were directors at the beginning of the two-year period or whose election or nomination for election was
previously so approved, cease for any reason to constitute a majority thereof; or 

  

	 	iii.	The consummation by the Company (whether directly involving the Company or indirectly involving the Company through one or more intermediaries) of (x) a merger,
consolidation, reorganization, or business combination or (y) a sale or other disposition of all or substantially all of the Company’s assets in any single transaction or series of related transactions or (z) the acquisition of assets
or stock of another entity, in each case other than a transaction: 

  

	 	(A)	Which results in the Company’s voting securities outstanding immediately before the transaction continuing to represent (either by remaining outstanding or by
being converted into voting securities of the Company or the person that, as a result of the transaction, controls, directly or indirectly, the Company or owns, directly or indirectly, all or substantially all of the Company’s assets or
otherwise succeeds to the business of the Company (the Company or such person, the “ Successor Entity “)) directly or indirectly, at least a majority of the combined voting power of the Successor Entity’s outstanding voting securities
immediately after the transaction, and; 

  

	 	(B)	After which no person or group (as such terms are used in Sections 13(d) and 14(d)(2) of the Exchange Act) beneficially owns (within the meaning of Rule 13d-3 under the
Exchange Act) voting securities representing 50% or more of the combined voting power of the Successor Entity; provided, however, that no person or group shall be treated for purposes of this clause (iii)(B) as beneficially owning 50% or more of

limitation, excise taxes assessed on Indemnitee with respect to any employee benefit plan. 
 2. Indemnification.

 2.1 Indemnification with Respect to Proceedings Other Than Proceedings by or in the Right of the
Company. In the event that Indemnitee was, is or becomes a party to or witness or other participant in, or is threatened to be made a party to, or witness or other participant in, any Proceeding (other than a Proceeding by or in the right of the
Company) by reason of (or arising in whole or in part from) an Indemnifiable Event, the Company shall indemnify the Indemnitee, to the fullest extent permitted by applicable law, from and against all Expenses, judgments, penalties, fines and amounts
paid in settlement actually and reasonably incurred by Indemnitee, or on behalf of Indemnitee, in connection with such Proceeding, provided that, in the case of amounts paid in settlement, any settlement of such Proceeding is approved in advance by
the Company in writing, which approval shall not be unreasonably withheld, delayed or applied in an inconsistent manner. 
 2.2 Indemnification with Respect to Proceedings by or in the Right of the Company. In the event that Indemnitee was, is or becomes a party to, or witness or other participant in, any Proceeding
brought by or in the right of the Company to procure a judgment in favor of the Company by reason of (or arising in whole or in part from) an Indemnifiable Event, the Company shall indemnify Indemnitee, to the fullest extent permitted by applicable
law, from and against all Expenses and amounts paid in settlement actually and reasonably incurred by Indemnitee, or on behalf of Indemnitee, in connection with such Proceeding. 
 2.3 Partial Indemnification. If Indemnitee is entitled under any provision of this Agreement to indemnification by the
Company for some portion of the Expenses, judgments, penalties, fines and amounts paid in settlement of a Proceeding which Indemnitee was, is or becomes a party to, or witness or other participant in, or is threatened to be made a party to, or
witness or other participant in, by reason of an Indemnifiable Event, but not, however, for all of the total amount of such Expenses, judgments, fines, penalties and amounts paid in settlement, the Company will nevertheless indemnify Indemnitee for
the portion thereof to which Indemnitee is entitled. 
 2.4 Indemnification for Expenses of a Party Who is
Wholly or Partly Successful. Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is, by reason of an Indemnifiable Event, made a party to and is successful, on the merits or otherwise, in the defense of, any
Proceeding, Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by Indemnitee, or on behalf of Indemnitee, in connection therewith. Without limiting any other rights of Indemnitee in this Agreement, if Indemnitee is
not wholly successful in such Proceeding but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses actually and
reasonably incurred by him or on his behalf in connection with each successfully resolved claim, issue or matter. For purposes of this Section and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal,
with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter. 
  

 4 

 3. Advance of Expenses. The Company shall advance all Expenses reasonably incurred by
or on behalf of Indemnitee in connection with any Proceeding to which Indemnitee is, or is threatened to be made, a party or with respect to which Indemnitee is, or is threatened to be made, a witness or other participant, by reason of (or arising
in whole or in part from) an Indemnifiable Event, whether prior to or after final disposition of such Proceeding, to the fullest extent permitted by applicable law and without requiring a preliminary determination as to Indemnitee’s ultimate
entitlement to indemnification, within ten days after the receipt by the Company of a statement or statements from Indemnitee requesting such advance or advances from time to time. Such statement or statements shall reasonably evidence the Expenses
incurred by Indemnitee and, if required by applicable law, shall include or be preceded or accompanied by (a) a written affirmation by the Indemnitee of the Indemnitee’s good faith belief that the standard of conduct necessary for
indemnification by the Company as authorized by law and by this Agreement has been met and (b) a written undertaking by or on behalf of Indemnitee to repay any Expenses advanced if it shall ultimately be determined that such standard of conduct
has not been met. Any such undertaking which may be required under this Section 3 shall be an unlimited general obligation by or on behalf of Indemnitee and shall be accepted without reference to Indemnitee’s financial ability to make the
repayment, need not be secured, and shall not require the payment of interest on any such advances. 
 4. Procedure for
Determination of Entitlement to Indemnification. 
 4.1 Request for Indemnification. To obtain
indemnification under this Agreement, Indemnitee shall submit to the Company a written request, including therein or therewith such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine
whether and to what extent Indemnitee is entitled to indemnification. Promptly upon receipt of such a request for indemnification, the Company shall cause its Board of Directors to be so advised in writing that Indemnitee has requested
indemnification. 
 4.2 Determination of Right to Indemnification. Upon written request by Indemnitee for
indemnification pursuant to the first sentence of Section 4.1 hereof, a determination, if required by applicable law, with respect to Indemnitee’s entitlement thereto shall promptly be made in the specific case: (i) if a Change in
Control shall have occurred, by Independent Counsel in a written opinion to the Board of Directors, a copy of which shall be delivered to Indemnitee; or (ii) if a Change in Control shall not have occurred, (A) by the Board of Directors by
a majority vote of a quorum consisting of Disinterested Directors, or (B) if a quorum of the Board of Directors consisting of Disinterested Directors is not obtainable or, even if obtainable, such quorum of Disinterested Directors so directs,
by Independent Counsel in a written opinion to the Board of Directors, a copy of which shall be delivered to Indemnitee or (C) if so directed by a majority of the members of the Board of Directors, by the stockholders of the Company. If it is
determined that Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within ten days after such determination. Indemnitee shall cooperate with the person making such determination with respect to Indemnitee’s
entitlement to

  

 5 

 
indemnification, including providing to such person upon reasonable advance request any documentation or information which is not privileged or otherwise protected from disclosure and which is
reasonably available to Indemnitee and reasonably necessary to such determination. Any costs or expenses (including reasonable attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the person making such
determination, in response to a request by such person, shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to indemnification). 
 5. Presumptions and Effect of Certain Proceedings. 
 (a) In making a determination with respect to entitlement to indemnification hereunder, (i) the person making such
determination shall presume that Indemnitee is entitled to indemnification under this Agreement if Indemnitee has submitted a request for indemnification in accordance with Section 4.1 of this Agreement, and (ii) the Company shall have the
burden of proof to overcome that presumption in connection with the making of any determination contrary to that presumption. 
 (b) The termination of any proceeding by judgment, order, settlement, conviction, a plea of nolo contendere or its equivalent, or an entry of an order of probation prior to judgment, does not
create a presumption that the Indemnitee did not meet the requisite standard of conduct required under applicable law for indemnification. 
 6. Remedies of Indemnitee. 
 (a) In the event that
(i) a determination is made pursuant to Section 4.2 that Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 3, (iii) no determination of
entitlement to indemnification shall have been made pursuant to Section 4.2 within sixty days after receipt by the Company of the request for indemnification, (iv) payment of indemnification is not made pursuant to Section 2.4 within
ten days after receipt by the Company of a written request therefor, or (v) payment of indemnification is not made within ten days after a determination has been made that Indemnitee is entitled to indemnification, Indemnitee shall be entitled
to an adjudication in an appropriate court of the State of Maryland, or in any other court of competent jurisdiction, of his entitlement to such indemnification or advancement of Expenses. Neither the failure of the Board of Directors or a committee
thereof, or the stockholders of the Company, or Independent Counsel to have made a determination pursuant to Section 4.2 that Indemnitee is entitled to indemnification, nor an actual determination by the Board of Directors or a committee
thereof, or the stockholders, of the Company, or Independent Counsel, that Indemnitee is not entitled to indemnification shall be a defense to any judicial adjudication sought by Indemnitee or create a presumption that the Indemnitee is not entitled
to indemnification or advancement of Expenses. 
 (b) In any judicial proceeding commenced pursuant to this
Section 6, the Company shall have the burden of proving that Indemnitee is not entitled to indemnification or advancement of Expenses, as the case may be. 
  

 6 

 (c) If a determination shall have been made pursuant to Section 4.2 of
this Agreement that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding commenced pursuant to this Section 6, absent (i) a misstatement by Indemnitee of a material fact, or
an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law. 
 (d) In the event that Indemnitee, pursuant to this Section 6, seeks a judicial adjudication to establish or enforce
Indemnitee’s rights under, or to recover damages for breach of, this Agreement, Indemnitee shall be entitled to recover from the Company, and shall be indemnified by the Company against, any and all expenses (of the types described in the
definition of Expenses in Section 1) actually and reasonably incurred by Indemnitee in connection with such judicial adjudication, regardless of the outcome of such judicial adjudication unless the court in such judicial adjudication determines
that the material assertions made by Indemnitee in such judicial adjudication were not made in good faith or were frivolous. 
 7. Indemnification Hereunder Not Exclusive. The indemnification provided by this Agreement shall not be deemed exclusive of, and shall be in addition to, any indemnification or other rights to which the Indemnitee may be entitled
under the Charter, the Bylaws, any vote of stockholders or Disinterested Directors, applicable law, or otherwise, both as to action in his official capacity and as to action in another capacity on behalf of the Company while holding office;
provided, however, that to the extent that the Indemnitee otherwise would have any greater right to indemnification under any provision of the Charter or Bylaws as in effect on the date hereof, the Indemnitee shall be deemed to have such greater
right hereunder; and provided, further, that to the extent that any change is made to the Charter and/or Bylaws which permits any greater right to indemnification than that provided under this Agreement, the Indemnitee shall be entitled to have such
greater right. No modification or amendment of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any Indemnifiable Event prior to such modification or amendment. 

8. Liability Insurance. To the extent that the Company maintains liability insurance for directors, officers, employees, or agents
of the Company or of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise which such person serves at the request of the Company, Indemnitee shall be covered by such policy or policies in accordance
with its or their terms to the maximum extent of the coverage available for any such director, officer, employee or agent under such policy or policies. 
 9. Subrogation. In the event of any payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the related rights of recovery of Indemnitee against other
person or entities, and Indemnitee shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as are necessary to enable the Company to bring suit to enforce such rights. 

10. No Duplication of Payment. The Company shall not be liable under this Agreement to make any payment of amounts otherwise
indemnifiable hereunder if and to the extent that Indemnitee has otherwise actually received payment of such amount under any insurance policy, contract, agreement, any provision of the Charter or Bylaws, or otherwise. 
  

 7 

 11. Exclusions. Notwithstanding any other provision of this Agreement to the
contrary, the Company shall not be liable for, and the Indemnitee shall not be entitled to, indemnification or advance of Expenses under this Agreement with respect to: (i) any settlement or judgment for insider trading or for disgorgement of
profits pursuant to Section 16(b) of the Securities Exchange Act of 1934; or (ii) any Proceeding initiated or brought by Indemnitee, and not by way of defense (other than an action or proceeding under Section 6 of this Agreement),
unless the bringing of such Proceeding has been approved by the Board of Directors. 
 12. Duration of Agreement. This
Agreement shall continue until and terminate ten years after the date that Indemnitee shall have ceased to serve as a director, officer, employee, or agent of the Company or of any other corporation, partnership, limited liability company,
association, joint venture, trust, employee benefit plan or other entity or enterprise which Indemnitee served at the request of the Company; provided, that the rights of Indemnitee hereunder shall continue until the final termination of any
Proceeding then pending in respect of which Indemnitee is granted rights of indemnification or advancement of Expenses hereunder and of any proceeding commenced by Indemnitee pursuant to Section 6 relating thereto. 
 13. Successors and Assigns. This Agreement shall be binding upon the Company and its successors and assigns and shall inure to the
benefit of Indemnitee and his or her spouse, assigns, heirs, executors, administrators and other legal representatives. The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and assets of the Company, by written agreement, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform if no such succession
had taken place. 
 14. Severability. If any provision or provisions of this Agreement shall be held to be invalid,
illegal or unenforceable for any reason whatsoever: (i) the validity, legality and enforceability of the remaining provisions of this Agreement (including, without limitation, each portion of any section of this Agreement containing any such
provision held to be invalid, illegal or unenforceable that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby; and (ii) to the fullest extent possible, the provisions of this Agreement
(including, without limitation, each portion of any section of this Agreement containing any such provision held to be invalid, illegal or unenforceable that is not itself invalid, illegal or unenforceable) shall be construed so as to give effect to
the intent manifested thereby. 
 15. Counterparts. This Agreement may be executed in one or more counterparts, each of
which shall for all purposes be deemed to be an original but all of which together shall constitute one and the same Agreement. Only one such counterpart signed by the party against whom enforceability is sought needs to be produced to evidence the
existence of this Agreement. 
  

 8 

 16. Headings. The headings of the paragraphs of this Agreement are inserted for
convenience only and shall not be deemed to constitute part of this Agreement or to affect the construction thereof. 
 17.
Modification and Waiver. No supplement, modification or amendment of this Agreement shall be binding unless executed in writing by both of the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall
constitute a waiver of any other provisions hereof (whether or not similar) nor shall such waiver constitute a continuing waiver. 
 18. Notice by Indemnitee; Company Participation. 
 (a) Indemnitee shall promptly notify the
Company in writing upon being served with any summons, citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter which may be subject to indemnification or advance of Expenses covered hereunder.

 (b) With respect to any Proceeding which may be subject to indemnification or advance of Expenses under this
Agreement, unless Indemnitee waives its indemnification rights under this Agreement with respect to such Proceeding, the Company will be entitled to participate in the Proceeding at its own expense and, except as otherwise provided below, if it so
elects, the Company may assume the defense of the Proceeding, with counsel satisfactory to the Indemnitee. After notice from the Company to the Indemnitee of its election to assume the defense of a Proceeding, during the Company’s good faith
active defense, the Company will not be liable to the Indemnitee under this Agreement for any Expenses subsequently incurred by the Indemnitee in connection with the defense of the Proceeding, other than reasonable costs of investigation or as
otherwise provided below. The Company shall not settle any such Proceeding in any manner which would impose any penalty or limitation on the Indemnitee without the Indemnitee’s written consent. The Indemnitee shall have the right to employ
separate counsel in any such Proceeding, but the fees the expenses of such counsel incurred after notice from the Company of its assumption of the defense of the Proceeding shall be at the expense of the Indemnitee, unless (i) the employment of
counsel by Indemnitee has been authorized by the Company, (ii) the Indemnitee shall have reasonably concluded that there may be conflict of interest between the Company and the Indemnitee in the conduct of the defense of the Proceeding, or
(iii) the Company shall not in fact have employed counsel to assume the defense of a Proceeding, in each of which cases the fees and expenses of Indemnitee’s counsel shall be Expenses for which Indemnitee may receive indemnification or
advances under this Agreement. The Company shall not be entitled to assume the defense of any Proceeding bought by or on behalf of the Company or as to which the Indemnitee has reasonably concluded there may be a conflict of interest between the
Company and the Indemnitee.

 11Separation Agreement

 Exhibit 10.90 
 EXECUTION VERSION 
 SEPARATION AGREEMENT AND RELEASE

 This SEPARATION AGREEMENT AND RELEASE (“Agreement”) is entered into on
this 16th day of December, 2009, by and between Richard E.
Moran Jr. (the “Executive”), Kilroy Realty, L.P. and Kilroy Realty Corporation (the “Company”). In consideration of the mutual covenants contained herein, the sufficiency of which is hereby acknowledged, the parties
agree as follows: 
 1. Separation from Employment. Executive and the Company mutually agree that Executive’s
employment with the Company and its affiliates, including Kilroy Realty, L.P., shall terminate effective as of December 31, 2009 (the “Separation Date”) pursuant to Section 6(c) of the Employment Agreement, as amended, by
and between the Company and the Executive, which became effective as of January 1, 2007 (the “Employment Agreement”). Effective as of December 15, 2009, Executive and the Company mutually agree that Executive shall no
longer serve as an officer or director of the Company or any of its affiliates, including Kilroy Realty, L.P., but shall continue in employment with the Company through December 31, 2009. 
 2. Separation Benefits. Subject to compliance with Section 3 of this Agreement and the condition set forth in Section 4 of
this Agreement, Executive shall be entitled to receive and the Company shall pay and provide Executive with the following compensation and benefits, less any tax or other legally required withholdings: 
 (i) Executive’s Compensation Accrued at Termination (as defined in the Employment Agreement), including any accrued
vacation, payable as part of the Company’s regularly scheduled pay period concurrent with or next following the Separation Date; 
 (ii) in lieu of a Partial Year Bonus (as defined in the Employment Agreement), a bonus under the Company’s 2009 annual bonus program based on actual performance of the Company for 2009, which bonus
shall be paid to Executive in cash no later than January 31, 2010, subject to any deferrals previously elected by Executive; provided that any bonus that would have otherwise been payable in stock shall be deferred in accordance with
Executive’s existing stock deferral election; 
 (iii) $5,650,488 as Executive’s severance payment
under Section 6(c)(iii) of the Employment Agreement payable six months and one day following the Separation Date; 
 (iv) $250,000 in payment of Executive’s Long-Term Incentive Award, as a performance based awards under Section 6(c)(v) of the Employment Agreement, payable within 50 days of the Separation Date; 
 (v) full vesting in 92,799 restricted stock units and 15,996 shares of restricted stock pursuant to Section 6(iv) of the
Employment Agreement; 

 (vi) $240,000 as an additional past service, loyalty and cooperation bonus
payable within 50 days of the Separation Date; 
 (vii) health insurance coverage (i.e., medical, dental and
vision) pursuant to Federal COBRA/Cal-COBRA for Executive and his spouse and eligible dependent children under the Company’s group health plans in which Executive was participating on the Separation Date or if the applicable health insurance
plan is terminated after the Separation Date, in the applicable health insurance plan in which senior executives of the Company participate following the termination of such plan. Executive agrees that he and his spouse and eligible dependent
children, as applicable, shall elect Federal COBRA/Cal-COBRA continuation coverage within the time period permitted by Federal COBRA/Cal-COBRA and, subject to such election, the Company agrees to pay the cost of the premiums for such Federal
COBRA/Cal-COBRA continuation coverage. Following the applicable Federal COBRA/Cal-COBRA continuation coverage period, Executive shall be entitled to a monthly payment of $4,166.67 paid during each month remaining in the thirty-six (36) month
period immediately following the Separation Date. For example, if Executive remains covered under Federal COBRA/Cal-COBRA for twenty-nine (29) months following the Separation Date, then the Company will provide Executive with a monthly payment
of $4,166.67 during each of the seven (7) months immediately following the end of the Federal COBRA/Cal-COBRA continuation period. Following the Federal COBRA/Cal-COBRA continuation period, Executive may be eligible to participate in HIPAA
plans or conversion plans in order to obtain health insurance coverage; 
 (viii) to assist Executive and his
spouse with potential unreimbursed medical expenses and medical insurance premiums during the period beginning on January 1, 2010 and ending on December 31, 2014 (the “Medical Reimbursement Period”), reimbursement for
expenses (the “Medical Expenses”) referred to in Section 105(b) of the Internal Revenue Code of 1986, as amended, incurred by Executive or his spouse during the Medical Reimbursement Period that are not otherwise paid for by,
or eligible for reimbursement under, insurance coverage, whether private or governmental insurance, and, with respect to months where Executive is eligible to receive a payment of $4,166.67 pursuant to clause (vii), only with respect to Medical
Expenses incurred in excess of $4,166.67 for the particular month. Notwithstanding the foregoing, the reimbursement for Medical Expenses pursuant to this clause (viii) shall not exceed an overall maximum reimbursement amount of $250,000. In
addition, as a condition to reimbursement under this clause (viii), Executive agrees to, and agrees to cause his spouse to, fully and timely apply for all available government medical insurance programs and to use commercially reasonable efforts to
obtain private medical insurance coverage, in each case, to cover Medical Expenses, and to seek payment or reimbursement for Medial Expenses from both private and governmental insurance, as applicable, during the Medical Reimbursement Period;
provided, that Executive and his spouse shall remain eligible for reimbursement under this clause (viii) if Executive or his spouse, as applicable, is unable to obtain medical insurance coverage during the Medical Reimbursement Period after
making such applications and using such commercially reasonable efforts to obtain such coverage; and 
  

 2 

 (ix) reimburse Executive for expenses incurred by Executive in calendar year
2010 for tax and financial planning services up to a maximum of $39,145 provided, that such reimbursement by the Company shall be made no later than March 15, 2011; provided, further, that Executive shall have provided a reasonably detailed
reimbursement request with respect to such services to the Company no later than February 1, 2011 in order to receive such reimbursement. 
 Executive agrees that the payments and benefits to be received under Sections 2(i)-(ix) are in full satisfaction of all amounts to which he may be entitled under the Employment Agreement. For the
avoidance of doubt, all of Executive’s deferred compensation, including any dividend equivalents that have been deferred, will be settled in accordance with the plans and programs governing the deferred compensation. Any amount that Executive
is entitled to be reimbursed under this Agreement will be reimbursed to Executive as promptly as practical and in any event not later than the end of the calendar year following the calendar year in which the expenses are incurred; provided that
Executive shall have provided a reasonably detailed reimbursement request to the Company no later than thirty (30) days prior to the last date the reimbursement is due. The amount of the expenses eligible for reimbursement during any calendar
year will not affect the amount of expenses for reimbursement in any other calendar year, except as provided in Section 2(viii), and the right to reimbursement or in-kind benefits are not subject to liquidation or exchange for another benefit.

 3. Cooperation. At the request of the Company, Executive agrees to cooperate to the fullest extent possible with
respect to legal and operational matters involving the Company and its affiliates about which Executive has or may have personal knowledge, including reasonable cooperation in the professional transition of those matters for which he was responsible
and involved in during his employment with the Company and any such matters which may arise after the Separation Date. 
 4.
Release. For and in consideration of the payments and benefits payable and provided to the Executive under Section 2(ii)-(vii) above (the “Separation Benefits”), and for other good and valuable consideration, the
Executive hereby agrees, for the Executive, the Executive’s spouse and child or children (if any), the Executive’s heirs, beneficiaries, devisees, executors, administrators, attorneys, personal representatives, successors and assigns, to
forever release, discharge and covenant not to sue the Company, or any of its divisions, affiliates (including Kilroy Realty LP, Kilroy Realty Corporation, Kilroy Realty Finance, Inc., Kilroy Services LLC, Kilroy Realty TRS, Inc., Kilroy Industries,
The John B. and Nelly Llanos Kilroy Foundation, John B. Kilroy, Jr., or John B. Kilroy, Jr.’s spouse or immediate family members, John B. Kilroy, Sr., or his spouse or immediate family members), subsidiaries, parents, branches, predecessors,
successors, assigns, and, with respect to such entities and individuals, their officers, directors, trustees, employees, agents, shareholders, administrators, general or limited partners, representatives, attorneys, insurers and fiduciaries, past,
present and future (the “Released Parties”) from any and all claims of any kind arising out of, or related to, his employment with the Company, its affiliates and subsidiaries (collectively, with the Company, the “Affiliated
Entities”) or the Executive’s separation from employment with the Affiliated Entities, which the Executive now has or may have against the Released Parties, whether known or unknown to the Executive, by reason of facts which have
occurred on or prior to the

  

 3 

 
Separation Date. Such released claims include, without limitation, any and all claims relating to the foregoing under federal, state or local laws pertaining to employment, including, without
limitation, the Age Discrimination in Employment Act, Title VII of the Civil Rights Act of 1964, as amended, 42 U.S.C. Section 2000e et. seq., the Fair Labor Standards Act, as amended, 29 U.S.C. Section 201 et. seq., the Americans with
Disabilities Act, as amended, 42 U.S.C. Section 12101 et. seq. the Reconstruction Era Civil Rights Act, as amended, 42 U.S.C. Section 1981 et. seq., the Rehabilitation Act of 1973, as amended, 29 U.S.C. Section 701 et. seq., the
Family and Medical Leave Act of 1992, 29 U.S.C. Section 2601 et. seq., the California Fair Employment and Housing Act, the California Family Rights Act; the California Labor Code, the California Occupational Safety and Health Act,
Section 17200 of the California Business and Professions Code and any and all state or local laws regarding employment discrimination and/or federal, state or local laws of any type or description regarding employment, including but not limited
to any claims arising from or derivative of the Executive’s employment with the Affiliated Entities, as well as any and all such claims under state contract or tort law. 
 The Executive has read this Agreement carefully, acknowledges that the Executive has been given at least 21 days to consider all of its
terms and has been advised to consult with any attorney and any other advisors of the Executive’s choice prior to executing this Agreement, and the Executive fully understands that by signing below the Executive is voluntarily giving up any
right which the Executive may have to sue or bring any other claims against the Released Parties, including any rights and claims under the Age Discrimination in Employment Act. The Executive also understands that the Executive has a period of seven
days after signing this Agreement within which to revoke Executive’s release of claims under the Age Discrimination in Employment Act, and that neither the Company nor any other person is obligated to make any payments or provide any of the
Separation Benefits to the Executive pursuant to the Agreement until eight days have passed since the Executive’s signing of this Agreement without the Executive’s signature having been revoked other than any accrued obligations or other
benefits payable pursuant to the terms of the Company’s normal payroll practices or employee benefit plans. Executive’s right to revoke is limited solely to the Age Discrimination in Employment Act and shall not be construed as a general
right to revoke this Agreement or any other provisions thereof. If Executive revokes his release of claims under the Age Discrimination in Employment Act, all remaining terms in this Agreement shall continue to have full force and effect and the
Agreement shall continue to be enforceable as if the Age Discrimination in Employment Act release was severed, but neither the Company nor any other person shall be obligated to make any payments or provide any of the Separation Benefits to the
Executive pursuant to the Agreement other than $100 as consideration for the remaining claims released hereunder. Finally, the Executive has not been forced or pressured in any manner whatsoever to sign this Agreement, and the Executive agrees to
all of its terms voluntarily. 
 EXECUTIVE ACKNOWLEDGES THAT HE IS FAMILIAR WITH THE PROVISIONS OF CALIFORNIA CIVIL CODE SECTION
1542, WHICH PROVIDES AS FOLLOWS: 
 A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO
EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM OR HER MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR. 
  

 4 

 BEING AWARE OF SAID CODE SECTION, EXECUTIVE EXPRESSLY WAIVES ANY RIGHTS HE MAY HAVE
THEREUNDER, AS WELL AS UNDER ANY OTHER STATUTES OR COMMON LAW PRINCIPLES OF SIMILAR EFFECT. 
 Notwithstanding anything else
herein to the contrary, this Agreement shall not affect: (i) the Company’s obligations under any compensation or employee benefit plan, program or arrangement (including, without limitation, obligations to the Executive under the
Employment Agreement, any stock option, stock award or agreements or obligations under any pension, deferred compensation or retention plan) provided by the Affiliated Entities where the Executive’s compensation or benefits are intended to
continue or the Executive is to be provided with compensation or benefits, in accordance with the express written terms of such plan, program or arrangement, beyond the Separation Date; (ii) rights to indemnification the Executive may have
under the Employment Agreement, any other separate agreement entered into with the Company, any directors and officers liability insurance, the Company’s By-laws or Articles of Incorporation or California Labor Code Section 2802;
(iii) rights Executive may have as a shareholder, unit holder or prior member of the operating partnership; (iv) claims for unemployment compensation or any state disability insurance benefits pursuant to the terms of applicable state law;
(v) without waiver of the releases set forth in this Agreement, Executive’s right to bring to the attention of the Equal Employment Opportunity Commission or the California Department of Fair Employment and Housing claims of
discrimination, though Executive acknowledges that he shall not be entitled to recover any damages individually as a result of an action resulting from an action that arises, directly or indirectly, from such notification; or (vi) any claims
that can not be waived by law. 
 5. Miscellaneous. This Agreement is final and binding and may not be changed or
modified except in a writing signed by both parties. Section 12 of the Employment Agreement shall apply to this Release.
