Exhibit 10.1

EMPLOYMENT AGREEMENT

THIS EMPLOYMENT AGREEMENT (this “Agreement”) is made and entered into this 13^th day of December, 2023, by and among Kilroy Realty Corporation, a Maryland corporation (“Kilroy”), Kilroy Realty, L.P., a Delaware limited partnership (“KRLP”), and Angela Aman (the “Executive”). (For purposes of this Agreement, the term “Company” means Kilroy, KRLP, either of them, or both of them together, as the context may require.)

RECITALS

THE PARTIES ENTER THIS AGREEMENT on the basis of the following facts, understandings and intentions:

A. KRLP desires to employ the Executive, and the Executive desires to accept such employment, on the terms and conditions set forth in this Agreement.

B. This Agreement shall be effective as set forth herein and shall govern the relationship between the Executive, on the one hand, and Kilroy and KRLP, on the other hand, from and after the Effective Date, and, as of the Effective Date, supersedes and negates all previous agreements and understandings between them with respect to such relationship.

AGREEMENT

NOW, THEREFORE, in consideration of the above recitals incorporated herein and the mutual covenants and promises contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby expressly acknowledged, the parties agree as follows:

1

2

3

The allocation of the rights and obligations between Kilroy and KRLP shall be determined by separate agreement of those parties. (For clarity, as to any specific salary, award, benefit, severance or other compensation provided for in this Agreement, Executive shall be entitled to the amount specified in this Agreement from either Kilroy or KRLP, as Kilroy and KRLP may determine in their discretion unless otherwise expressly provided in this Agreement, and not from each of them.)

4

Provided that the Executive is employed with the Company on the date Kilroy grants annual equity awards to its executive officers generally for that fiscal year, Kilroy will grant the Executive an annual equity award for each of fiscal year 2024 and fiscal year 2025 with a grant date fair value (as determined by Kilroy applying the equity award valuation methodology used by Kilroy for its financial reporting purposes) of an amount no less than Three Million Five Hundred Thousand Dollars ($3,500,000) (subject to rounding for whole share increments). The types of equity awards granted, the allocation of that value between those types of awards granted, specific vesting terms, and other terms and conditions of the awards will be determined by the Board (or a committee thereof).

5

6

(a) The Company shall pay the Executive (or, in the event of the Executive’s death, the Executive’s estate) any Accrued Obligations;

(b) If the Executive’s employment with the Company terminates during the Period of Employment as a result of a termination by the Company without Cause (other than due to the Executive’s death or Disability) or a resignation by the Executive for Good Reason, and in either case Section 5.3(c) does not apply, the Executive shall be entitled to the following benefits:

7

(i) The Company shall pay the Executive (in addition to the Accrued Obligations), subject to tax withholding and other authorized deductions, an amount equal to two (2) times the Executive’s Base Salary at the annualized rate in effect on the Severance Date plus two (2) times the Executive’s target level of annual Incentive Bonus as in effect on the Severance Date. Subject to Section 22(b), the Company shall pay such severance benefit to the Executive in equal monthly installments (each representing the applicable fraction of such total benefit amount, rounded down to the nearest whole cent) over a period of twenty-four (24) consecutive months commencing with the month following the month in which the Executive’s Separation from Service occurs, with the first installment payable on (or within ten (10) days following) the sixtieth (60^th) day following the Executive’s Separation from Service and to include each such installment that was otherwise (but for such 60-day delay) scheduled to be paid following the Executive’s Separation from Service and prior to the date of such payment.

(ii) The Company will pay or reimburse the Executive for the Executive’s premiums charged to continue medical coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act (“COBRA”), at the same or reasonably equivalent medical coverage for the Executive (and, if applicable, the Executive’s eligible dependents) as in effect immediately prior to the Severance Date, to the extent that the Executive elects such continued coverage; provided that the Company’s obligation to make any payment or reimbursement pursuant to this clause (ii) shall, subject to Section 22(b), commence with continuation coverage for the month following the month in which the Executive’s Separation from Service occurs and shall cease with continuation coverage for the eighteenth (18^th) month following the month in which the Executive’s Separation from Service occurs (or, if earlier, shall cease upon the date the Executive becomes eligible for coverage under the health plan of a future employer, or the date the Company ceases to offer group medical coverage to its active executive employees or the Company is otherwise under no obligation to offer COBRA continuation coverage to the Executive). To the extent the Executive elects COBRA coverage, the Executive shall complete any continuation coverage enrollment procedures the Company may then have in place. The Company’s obligations pursuant to this Section 5.3(b)(ii) are subject to the Company’s ability to comply with applicable law and provide such benefit without resulting in material adverse tax consequences (such as, without limitation, rendering participation in a Company health and welfare plan taxable to participants or resulting in unintended material (relative to the amount of the benefit) tax penalties for the Company).

(iii) The Company shall promptly pay to the Executive any Incentive Bonus that would otherwise be paid to the Executive had the Executive’s employment with the Company not terminated with respect to any fiscal year that ended before the Severance Date, to the extent not theretofore paid.

8

(iv) The Company shall pay, on (or within ten (10) days following) the sixtieth (60^th) day following the Executive’s Separation from Service, an amount in cash equal to (x) the Executive’s target Incentive Bonus for the fiscal year in which the Severance Date occurs, multiplied by (y) a fraction, the numerator of which is the total number of days in such fiscal year in which the Executive was employed by the Company and the denominator of which is the total number of days in such fiscal year.

(v) The Initial Award provided in Section 3.3, to the extent then outstanding and unvested, shall be fully vested as of the Severance Date.

(c) If the Executive’s employment with the Company terminates during the Period of Employment as a result of a termination by the Company without Cause (other than due to the Executive’s death or Disability) or a resignation by the Executive for Good Reason, and in either case such termination occurs within sixty (60) days prior to, upon, or at any time following a Change in Control of the Company, the Executive shall be entitled to the following benefits:

(i) The Company shall pay the Executive (in addition to the Accrued Obligations), subject to tax withholding and other authorized deductions, an amount equal to three (3) times the Executive’s Base Salary at the annualized rate in effect on the Severance Date plus three (3) times the Executive’s target level of annual Incentive Bonus as in effect on the Severance Date. Subject to Section 22(b), the Company shall pay such severance benefit to the Executive in equal monthly installments (each representing the applicable fraction of such total benefit amount, rounded down to the nearest whole cent) over a period of thirty-six (36) consecutive months commencing with the month following the month in which the Executive’s Separation from Service occurs, with the first installment payable on (or within ten (10) days following) the sixtieth (60th) day following the Executive’s Separation from Service and to include each such installment that was otherwise (but for such 60-day delay) scheduled to be paid following the Executive’s Separation from Service and prior to the date of such payment; provided, however, that if such Separation from Service occurs on or within two (2) years following a Change in Control that constitutes a change in the ownership or effective control of Kilroy, or in the ownership of a substantial portion of the assets of Kilroy (in each case, such a change in ownership, in effective control or of a substantial portion of assets to be determined within the meaning of Code Section 409A (as defined below)), then (subject to Section 22(b)) the Company shall pay such severance benefit to the Executive in a lump sum on (or within ten (10) days following) the sixtieth (60th) day following the Executive’s Separation from Service.

9

(ii) The Company will pay or reimburse the Executive for the Executive’s premiums charged to continue medical coverage pursuant to COBRA, at the same or reasonably equivalent medical coverage for the Executive (and, if applicable, the Executive’s eligible dependents) as in effect immediately prior to the Severance Date, to the extent that the Executive elects such continued coverage; provided that the Company’s obligation to make any payment or reimbursement pursuant to this clause (ii) shall, subject to Section 22(b), commence with continuation coverage for the month following the month in which the Executive’s Separation from Service occurs and shall cease with continuation coverage for the eighteenth (18^th) month following the month in which the Executive’s Separation from Service occurs (or, if earlier, shall cease upon the date the Executive becomes eligible for coverage under the health plan of a future employer, or the date the Company ceases to offer group medical coverage to its active executive employees or the Company is otherwise under no obligation to offer COBRA continuation coverage to the Executive). To the extent the Executive elects COBRA coverage, the Executive shall complete any continuation coverage enrollment procedures the Company may then have in place. The Company’s obligations pursuant to this Section 5.3(c)(ii) are subject to the Company’s ability to comply with applicable law and provide such benefit without resulting in material adverse tax consequences (such as, without limitation, rendering participation in a Company health and welfare plan taxable to participants or resulting in unintended material (relative to the amount of the benefit) tax penalties for the Company).

(iii) The Company shall promptly pay to the Executive any Incentive Bonus that would otherwise be paid to the Executive had the Executive’s employment with the Company not terminated with respect to any fiscal year that ended before the Severance Date, to the extent not theretofore paid.

(iv) The Company shall pay, on (or within ten (10) days following) the sixtieth (60^th) day following the Executive’s Separation from Service, an amount in cash equal to (x) the Executive’s target Incentive Bonus for the fiscal year in which the Severance Date occurs, multiplied by (y) a fraction, the numerator of which is the total number of days in such fiscal year in which the Executive was employed by the Company and the denominator of which is the total number of days in such fiscal year.

(v) Each equity award granted by the Company to the Executive that vests based solely on the Executive’s continued service with the Company, to the extent then outstanding and unvested, shall be fully vested as of the Severance Date. As to any equity award granted by the Company to the Executive that is then (on the Executive’s Severance Date) outstanding and subject to performance-based vesting requirements, the vesting of such award will continue to be governed by its terms, provided that any service-based vesting requirement under such outstanding equity-based award shall be deemed satisfied in full as of the Severance Date.

10

(d) If the Executive’s employment with the Company terminates during the Period of Employment as a result of the Executive’s death or Disability, the Company shall pay the Executive the amounts contemplated by Section 5.3(b)(iii) and (iv).

(e) Notwithstanding the foregoing provisions of this Section 5.3, if the Executive materially breaches the Executive’s obligations under the Restrictive Covenants Agreement or this Agreement at any time, from and after the date of such breach and not in any way in limitation of any right or remedy otherwise available to the Company, the Executive will no longer be entitled to, and the Company will no longer be obligated to pay, any remaining unpaid amount contemplated by Section 5.3(b) or 5.3(c); provided that, if the Executive provides the Release contemplated by Section 5.4, in no event shall the Executive be entitled to benefits pursuant to Section 5.3(b)(i) or 5.3(c)(i), as applicable, of less than $5,000 (or the amount of such benefits, if less than $5,000), which amount the parties agree is good and adequate consideration, in and of itself, for the Executive’s Release contemplated by Section 5.4.

(f) The foregoing provisions of this Section 5.3 shall not affect: (i) the Executive’s receipt of benefits otherwise due to terminated employees under group insurance coverage consistent with the terms of the applicable Company welfare benefit plan; (ii) the Executive’s rights under COBRA to continue health coverage; or (iii) the Executive’s receipt of benefits otherwise due in accordance with the terms of the Company’s 401(k) plan (if any).

(a) This Section 5.4 shall apply notwithstanding anything else contained in this Agreement or any stock option or other equity award agreement to the contrary. As a condition precedent to any Company obligation to the Executive pursuant to Section 5.3(b) or 5.3(c), or any other obligation to accelerate vesting of any equity award in connection with the termination of the Executive’s employment, the Executive shall timely provide each of Kilroy and KRLP with a valid, executed general release agreement in substantially the form attached hereto as Exhibit A (with such changes thereto as the Company may make, consistent with the intent of such release, to address changes in the law or to otherwise help ensure the validity and enforceability of the agreement) provided by the Company (the “Release”), and such Release shall have not been revoked by the Executive pursuant to any revocation rights afforded by applicable law. The Company shall provide the form of Release to the Executive not later than seven (7) days following the Severance Date, and the Executive shall be required to execute and return the Release to both Kilroy and KRLP within twenty-one (21) days (or forty-five (45) days if such longer period of time is required to make the Release maximally enforceable under applicable law) after the Company provides the form of Release to the Executive.

11

(b) The Company and the Executive acknowledge and agree that there is no duty of the Executive to mitigate damages under this Agreement. All amounts paid to the Executive pursuant to Section 5.3 shall be paid without regard to whether the Executive has taken or takes actions to mitigate damages. The Executive agrees to resign (and hereby does so resign), effective on the Severance Date, as an officer and director of each of Kilroy and KRLP, as well as any Affiliate of either of them, and as a fiduciary of any benefit plan of the Company or any Affiliate of the Company. The Executive further agrees to promptly execute and provide to the Company any further documentation, as reasonably requested by the Company, to confirm such resignations, and to remove the Executive as a signatory on any accounts maintained by Kilroy, KRLP, or any Affiliates of either of them (or any of their respective benefit plans).

(c) The Executive shall not be entitled to severance benefits pursuant to any other severance plan, policy or arrangement of Kilroy, KRLP, or any Affiliates of either of them.

(d) In the event that the Company provides the Executive notice of termination without Cause pursuant to Section 5.1 or the Executive provides the Company notice of termination pursuant to Section 5.2, the Company will have the option to place the Executive on paid administrative leave during the notice period.

(a) As used herein, “Accrued Obligations” means:

(i) any Base Salary that had accrued but had not been paid (including accrued and unpaid vacation time) on or before the Severance Date; and

(ii) any reimbursement due to the Executive pursuant to Section 4.2 or Section 4.5 (for clarity, no reimbursement will be due to the Executive pursuant to Section 4.5 for a termination of employment other than a termination of employment (x) described in Section 5.3(b) or 5.3(c) or (y) on account of the Executive’s death or Disability) for expenses reasonably incurred by the Executive on or before the Severance Date and documented and pre-approved, to the extent applicable, in accordance with the Company’s expense reimbursement policies in effect at the applicable time.

(b) As used herein, “Affiliate” of Kilroy, KRLP, or the Company means a Person that directly or indirectly through one or more intermediaries, controls, or is controlled by, or is under common control with, Kilroy, KRLP, or either of them. As used in this definition, the term “control,” including the correlative terms “controlling,” “controlled by” and “under common control with,” means the possession, directly or indirectly, of the power to direct or cause the direction of management or policies (whether through ownership of securities or any partnership or other ownership interest, by contract or otherwise) of a Person.

12

(c) As used herein, “Cause” shall mean, as reasonably determined by the Board (excluding the Executive, if the Executive is then a member of the Board) based on the information then known to it, that one or more of the following has occurred:

(i) the Executive is convicted of, pled guilty or pled nolo contendere to a felony or any crime involving fraud or dishonesty (in each case, under the laws of the United States or any relevant state, or a similar crime or offense under the applicable laws of any relevant foreign jurisdiction);

(ii) the Executive has engaged in acts of fraud, dishonesty or other acts of willful misconduct in the course of the Executive’s duties hereunder;

(iii) the Executive willfully fails to perform or uphold the Executive’s duties under this Agreement and/or willfully fails to comply with reasonable directives of the Board; or

(iv) a material breach by the Executive of this Agreement, the Restrictive Covenants Agreement, or any other contract the Executive is a party to with Kilroy, KRLP, or any Affiliate of either of them, or any written policy of Kilroy, KRLP, or any Affiliate of either of them that is applicable to Company executives or employees generally;

provided, however, that any condition or conditions, as applicable, referenced in clause (iii) or clause (iv) above shall not (if a cure is reasonably possible in the circumstances) constitute Cause unless both (x) the Company provides written notice to the Executive of such condition(s) claimed to constitute Cause (such notice to be delivered in accordance with Section 18), and (y) the Executive fails to remedy such condition(s) within thirty (30) days of receiving such written notice thereof (or, if a cure is reasonably possible in the circumstances but more than thirty (30) days is required to cure such circumstances, the Executive fails to commence taking reasonable steps to cure such condition(s) if it is not reasonably possible to remedy such condition within such thirty (30) day period, or the Executive fails to cure such condition(s) as promptly as reasonably possible and in all cases not more than ninety (90) days of receiving such written notice thereof). Furthermore, “Cause” shall not exist (other than pursuant to clause (i) above) unless the Board shall have afforded the Executive a reasonable opportunity to appear before the Board to address the circumstance(s) claimed to constitute Cause. For purposes of the foregoing definition of Cause, no act or failure to act, on the Executive’s part shall be considered “willful” unless done, or omitted to be done, by the Executive not in good faith and without reasonable belief that the Executive’s action or omission was in the best interest of the Company.

13

(d) As used herein, “Change in Control” shall mean:

(i) A transaction or series of transactions (other than an offering of Kilroy’s common stock to the general public through a registration statement filed with the Securities and Exchange 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”), and other than Kilroy, any of its subsidiaries, an employee benefit plan maintained by the Kilroy, KRLP, or any of its or their subsidiaries or a “person” that, prior to such transaction, directly or indirectly controls, is controlled by, or is under common control with, Kilroy) directly or indirectly acquires beneficial ownership (within the meaning of Rule 13d-3 under the Exchange Act) of securities of Kilroy and immediately after such acquisition possesses more than 50% of the total combined voting power of Kilroy’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 together with any new director(s) (other than a director designated by a person who shall have entered into an agreement with Kilroy to effect a transaction described in Section 5.5(d)(i) hereof or Section 5.5(d)(iii) hereof) whose election by the Board or nomination for election by Kilroy’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 Kilroy (whether directly involving Kilroy or indirectly involving Kilroy 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 Kilroy’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:

(x) Which results in Kilroy’s voting securities outstanding immediately before the transaction continuing to represent (either by remaining outstanding or by being converted into voting securities of Kilroy or the person that, as a result of the transaction, controls, directly or indirectly, Kilroy or owns, directly or indirectly, all or substantially all of Kilroy’s assets or otherwise succeeds to the business of Kilroy (Kilroy 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

14

(y) After which no person or group beneficially owns 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 Section 5.5(d)(iii)(y) as beneficially owning 50% or more of combined voting power of the Successor Entity solely as a result of the voting power held in Kilroy prior to the consummation of the transaction; or

(iv) Kilroy’s stockholders approve a liquidation or dissolution of Kilroy and all material contingencies to such liquidation or dissolution have been satisfied or waived.

(e) As used herein, “Disability” shall mean a physical or mental impairment which, as reasonably determined by the Board, renders the Executive unable to perform the essential functions of the Executive’s employment with KRLP, even with reasonable accommodation, for more than 90 days in any 180-day period, unless a longer period is required by federal or state law, in which case that longer period would apply. The Executive agrees to reasonably cooperate with the Board in making any such determination as to the existence of Disability.

(f) As used herein, “Good Reason” shall mean the occurrence (without the Executive’s consent) of any one or more of the following conditions:

(i) a material diminution by the Company in the Executive’s rate of Base Salary or target level of annual Incentive Bonus opportunity pursuant to Section 3.2, or (as to 2024 and 2025) the failure by the Company to grant any annual equity award required to be awarded by the Company pursuant to Section 3.4;

(ii) a material diminution by the Company in the Executive’s authority, duties, or responsibilities;

(iii) a material change by the Company in the geographic location of the Executive’s principal office with the Company (for this purpose, in no event shall a relocation of such office to a new location that is not more than fifty (50) miles from the current location of the Company’s executive offices constitute a “material change”); or

(iv) a material breach by the Company of this Agreement, the Restrictive Covenants Agreement, or any other contract the Executive is a party to with Kilroy, KRLP, or any Affiliate of either of them;

provided, however, that any such condition or conditions, as applicable, shall not constitute Good Reason unless both (x) the Executive provides written notice to the Company of the condition claimed to constitute Good Reason within sixty (60) days of the initial existence of such condition(s) (such notice to be delivered in accordance with Section 18), and (y) the Company fails to remedy such condition(s) within thirty (30) days of receiving such written notice thereof; and

15

provided, further, that in all events the termination of the Executive’s employment with the Company shall not constitute a termination for Good Reason unless such termination occurs not more than one hundred and twenty (120) days following the initial existence of the condition claimed to constitute Good Reason.

(g) As used herein, the term “Person” shall be construed broadly and shall include, without limitation, an individual, a partnership, a limited liability company, a corporation, an association, a joint stock company, a trust, a joint venture, an unincorporated organization and a governmental entity or any department, agency or political subdivision thereof.

(h) As used herein, a “Separation from Service” occurs when the Executive dies, retires, or otherwise has a termination of employment with the Company that constitutes a “separation from service” within the meaning of Treasury Regulation Section 1.409A-1(h)(1), without regard to the optional alternative definitions available thereunder.

(a) Notwithstanding anything contained in this Agreement to the contrary, to the extent that the payments and benefits provided under this Agreement and benefits provided to, or for the benefit of, the Executive under any other Company plan or agreement (such payments or benefits are collectively referred to as the “Benefits”) would be subject to the excise tax (the “Excise Tax”) imposed under Section 4999 of the Internal Revenue Code of 1986, as amended (the “Code”), the Benefits shall be reduced (but not below zero) if and to the extent that a reduction in the Benefits would result in the Executive retaining a larger amount, on an after-tax basis (taking into account federal, state and local income taxes and the Excise Tax), than if the Executive received all of the Benefits (such reduced amount is referred to hereinafter as the “Limited Benefit Amount”). Unless the Executive elects a different order of reduction, any such election to be consistent with the requirements of Section 409A of the Code, to the extent that a reduction

16

in payments or benefits is required pursuant to this Section 5.7(a), the Company shall reduce or eliminate amounts which are payable first from any cash severance and cash bonuses, then from any payment in respect of an equity award that is not covered by Treas. Reg. Section 1.280G-1 Q/A-24(b) or (c), then from any payment in respect of an equity award that is covered by Treas. Reg. Section 1.280G-1 Q/A-24(c), in each case in reverse order beginning with payments or benefits which are to be paid the farthest in time from the Determination (as defined below). Any election given by the Executive pursuant to the preceding sentence shall take precedence over the provisions of any other plan, arrangement or agreement governing the Executive’s rights and entitlements to any benefits or compensation. Nothing in this Section 5.7(a) shall require the Company or any of its affiliates to be responsible for, or have any liability or obligation with respect to, the Executive’s excise tax liabilities under Section 4999 of the Code so long as this Section 5.7(a) is correctly applied by the Company.

(b) A determination as to whether the Benefits shall be reduced to the Limited Benefit Amount pursuant to this Agreement and the amount of such Limited Benefit Amount shall be made by the Company’s independent public accountants or another certified public accounting firm or executive compensation consulting firm of national reputation designated by the Company (the “Firm”) at the Company’s expense. The Firm shall provide its determination (the “Determination”), together with detailed supporting calculations (including the value of any post-termination non-compete and other obligations of the Executive taken into account for purposes of the Determination) and documentation to the Company and the Executive within ten (10) business days of the date of termination of the Executive’s employment, if applicable, or such other time as reasonably requested by the Company or the Executive (provided the Executive reasonably believes that any of the Benefits may be subject to the Excise Tax), and if the Firm determines that no Excise Tax is payable by the Executive with respect to any Benefits, it shall furnish the Executive with an opinion reasonably acceptable to the Executive that no Excise Tax will be imposed with respect to any such Benefits. Unless the Executive provides written notice to the Company within ten (10) business days of the delivery of the Determination to the Executive that the Executive disputes such Determination, the Determination shall be binding, final and conclusive upon the Company and the Executive.

17

(a) This Agreement is personal to the Executive and without the prior written consent of the Company shall not be assignable by the Executive otherwise than by will or the laws of descent and distribution. This Agreement shall inure to the benefit of and be enforceable by the Executive’s legal representatives.

(b) This Agreement shall inure to the benefit of and be binding upon the Company and its successors and assigns. Without limiting the generality of the preceding sentence, the Company will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to assume expressly and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. As used in this Agreement, “Company” shall mean the Company as hereinbefore defined and any successor or assignee, as applicable, which assumes and agrees to perform this Agreement by operation of law or otherwise.

(a) It is intended that any amounts payable under this Agreement shall either be exempt from or comply with Section 409A of the Code (including the Treasury regulations and other published guidance relating thereto) (“Code Section 409A”) so as not to subject the Executive to payment of any additional tax, penalty or interest imposed under Code Section 409A. The provisions of this Agreement shall be construed and interpreted to avoid the imputation of any such additional tax, penalty or interest under Code Section 409A yet preserve (to the nearest extent reasonably possible) the intended benefit payable to the Executive. Any installment payments provided for in this Agreement shall be treated as a series of separate payments for purposes of Code Section 409A.

(b) If the Executive is a “specified employee” within the meaning of Treasury Regulation Section 1.409A-1(i) as of the date of the Executive’s Separation from Service, the Executive shall not be entitled to any payment or benefit pursuant to Section 5.3(b), 5.3(c), or 5.3(d) until the earlier of (i) the date which is six (6) months after the Executive’s Separation from Service for any reason other than death, or (ii) the date of the Executive’s death. The provisions of this Section 22(b) shall only apply if, and to the extent, required to avoid the imputation of any tax, penalty or interest pursuant to Code Section 409A. Any amounts otherwise payable to the Executive upon or in the six (6) month period following the Executive’s Separation from Service that are not so paid by reason of this Section 22(b) shall be paid (without interest) as soon as practicable (and in all events within thirty (30) days) after the date that is six (6) months after the Executive’s Separation from Service (or, if earlier, as soon as practicable, and in all events within thirty (30) days, after the date of the Executive’s death).

22

(c) To the extent that any benefits pursuant to Section 5.3(b)(ii), 5.3(c)(ii) or reimbursements pursuant to Section 4.2 or Section 4.5 are taxable to the Executive, any reimbursement payment due to the Executive pursuant to any such provision shall be paid to the Executive on or before the last day of the Executive’s taxable year following the taxable year in which the related expense was incurred (except as to any shorter payment timeframe provided for in Section 4.5 as to amounts subject thereto). The benefits and reimbursements pursuant to such provisions are not subject to liquidation or exchange for another benefit and the amount of such benefits and reimbursements that the Executive receives in one taxable year shall not affect the amount of such benefits or reimbursements that the Executive receives in any other taxable year.

(“KRLP”), each of their respective divisions, subsidiaries, parents, or affiliated corporations, past and present, and each of them, as well as its and their assignees, successors, directors, officers, stockholders, partners, representatives, attorneys, agents or employees, past or present, or any of them (individually and collectively, “Releasees”), from and with respect to any and all claims, agreements, obligations, demands and causes of action, known or unknown, suspected or unsuspected, arising out of or in any way connected with Executive’s employment or any other relationship with or interest in Kilroy, KRLP, or either of them, or the termination thereof, including without limiting the generality of the foregoing, any claim for severance pay, profit sharing, bonus or similar benefit, pension, retirement, life insurance, health or medical insurance or any other fringe benefit, or disability, or any other claims, agreements, obligations, demands and causes of action, known or unknown, suspected or unsuspected resulting from any act or omission by or on the part of Releasees committed or omitted prior to the date of this General Release Agreement (this “Agreement”) set forth below, including, without limiting the generality of the foregoing, any claim under Title VII of the Civil Rights Act of 1964, the Americans with Disabilities Act, the Family and Medical Leave Act, the California Fair Employment and Housing Act, California Labor Code Section 132a, the California Family Rights Act, or any other federal, state or local law, regulation, ordinance, constitution or common law (collectively, the “Claims”); provided, however, that the foregoing release does not apply to any obligation of the Company (as defined in the Employment Agreement (as such term is defined below)) to Executive pursuant to any of the following:

(1) Section 5.3 of the Employment Agreement dated as of December 13, 2023 by and among Kilroy, KRLP and Executive (the “Employment Agreement”);

(2) any equity-based awards previously granted by Kilroy to Executive, to the extent that such awards continue after the termination of Executive’s employment with the Company in accordance with the applicable terms of such awards;

(3) any right to indemnification that Executive may have pursuant to the Company’s bylaws, its corporate charter or under any written indemnification agreement with the Company (or any corresponding provision of any subsidiary or affiliate of the Company) with respect to any loss, damages or expenses (including but not limited to attorneys’ fees to the extent otherwise provided) that Executive may in the future incur with respect to Executive’s service as an employee, officer or director of the Company or any of its subsidiaries or affiliates;

(4) with respect to any rights that Executive may have to insurance coverage for such losses, damages or expenses under any Company (or subsidiary or affiliate) directors and officers liability insurance policy;

A-1

(5) any rights to continued medical and dental coverage that Executive may have under COBRA;

(6) any rights to payment of benefits that Executive may have under a retirement plan sponsored or maintained by the Company that is intended to qualify under Section 401(a) of the Internal Revenue Code of 1986, as amended; or

(7) any deferred compensation that Executive may be entitled to under a nonqualified deferred compensation plan of the Company.

In addition, this release does not cover any Claim that cannot be so released as a matter of applicable law. Notwithstanding anything to the contrary herein, nothing in this Agreement prohibits Executive from filing a charge with or participating in an investigation conducted by any state or federal government agencies. However, Executive does waive, to the maximum extent permitted by law, the right to receive any monetary or other recovery, should any agency or any other person pursue any claims on Executive’s behalf arising out of any claim released pursuant to this Agreement. For clarity, and as required by law, such waiver does not prevent Executive from accepting a whistleblower award from the Securities and Exchange Commission pursuant to Section 21F of the Securities Exchange Act of 1934, as amended. Executive acknowledges and agrees that Executive has received any and all leave and other benefits that Executive has been and is entitled to pursuant to the Family and Medical Leave Act of 1993.

2. Acknowledgement of Payment of Wages. Executive acknowledges that the Executive has received all amounts owed for Executive’s regular and usual salary (including, but not limited to, any bonus, incentive or other wages), and usual benefits through the date of this Agreement.

3. Waiver of Unknown Claims. This Agreement is intended to be effective as a general release of and bar to each and every Claim hereinabove specified. Accordingly, Executive hereby expressly waives any rights and benefits conferred by Section 1542 of the California Civil Code and any similar provision of any other applicable state law as to the Claims. Section 1542 of the California Civil Code provides:

“A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS THAT THE CREDITOR OR RELEASING PARTY DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE AND THAT, IF KNOWN BY HIM OR HER, WOULD HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR OR RELEASED PARTY.”

Executive acknowledges that the Executive later may discover claims, demands, causes of action or facts in addition to or different from those which Executive now knows or believes to exist with respect to the subject matter of this Agreement and which, if known or suspected at the time of executing this Agreement, may have materially affected its terms. Nevertheless, Executive hereby waives, as to the Claims, any claims, demands, and causes of action that might arise as a result of such different or additional claims, demands, causes of action or facts.

A-2

4. ADEA Waiver. Executive expressly acknowledges and agrees that by entering into this Agreement, Executive is waiving any and all rights or claims that Executive may have arising under the Age Discrimination in Employment Act of 1967, as amended (the “ADEA”), and that this waiver and release is knowing and voluntary. Executive and the Company agree that this waiver and release does not apply to any rights or claims that may arise under the ADEA after the date Executive signs this Agreement. Executive further expressly acknowledges and agrees that:

(a) In return for this Agreement, Executive will receive consideration beyond that which Executive was already entitled to receive before executing this Agreement;

(b) Executive is hereby advised in writing by this Agreement to consult with an attorney before signing this Agreement;

(c) Executive was given a copy of this Agreement on [_________, 202__], and informed that Executive had [twenty-one (21)] days within which to consider this Agreement and that if Executive wished to execute this Agreement prior to the expiration of such [21]-day period Executive will have done so voluntarily and with full knowledge that Executive is waiving Executive’s right to have [twenty-one (21)] days to consider this Agreement; and that such [twenty-one (21)] day period to consider this Agreement would not and will not be re-started or extended based on any changes, whether material or immaterial, that are or were made to this Agreement in such [twenty-one (21)] day period after Executive received it;

(d) Executive was informed that Executive had seven (7) days following the date of execution of this Agreement in which to revoke this Agreement, and this Agreement will become null and void if Executive elects revocation during that time. Any revocation must be in writing and must be received by the Company during the seven-day revocation period. In the event that Executive exercises this revocation right, neither the Company nor Executive will have any obligation under this Agreement. Any notice of revocation should be sent by Executive in writing to the Company (attention [_____________]), [Address], so that it is received within the seven-day period following execution of this Agreement by Executive.

(e) Nothing in this Agreement prevents or precludes Executive from challenging or seeking a determination in good faith of the validity of this waiver under the ADEA, nor does it impose any condition precedent, penalties or costs for doing so, unless specifically authorized by federal law.

5. No Transferred Claims. Executive represents and warrants to the Company that Executive has not heretofore assigned or transferred to any person not a party to this Agreement any released matter or any part or portion thereof.

A-3

6. Miscellaneous. The following provisions shall apply for purposes of this Agreement:

(a) Number and Gender. Where the context requires, the singular shall include the plural, the plural shall include the singular, and any gender shall include all other genders.

(b) Section Headings. The section headings of, and titles of paragraphs and subparagraphs contained in, this Agreement are for the purpose of convenience only, and they neither form a part of this Agreement nor are they to be used in the construction or interpretation thereof.

(c) Governing Law. This Agreement, and all questions relating to its validity, interpretation, performance and enforcement, as well as the legal relations hereby created between the parties hereto, shall be governed by and construed under, and interpreted and enforced in accordance with, the laws of the State of California, notwithstanding any California or other conflict of law provision to the contrary.

(d) Severability. If any provision of this Agreement or the application thereof is held invalid, the invalidity shall not affect other provisions or applications of this Agreement which can be given effect without the invalid provisions or applications and to this end the provisions of this Agreement are declared to be severable.

(e) Modifications. This Agreement may not be amended, modified or changed (in whole or in part), except by a formal, definitive written agreement expressly referring to this Agreement, which agreement is executed by both of the parties hereto.

(f) Waiver. No waiver of any breach of any term or provision of this Agreement shall be construed to be, nor shall be, a waiver of any other breach of this Agreement. No waiver shall be binding unless in writing and signed by the party waiving the breach.

(g) Arbitration. Any controversy arising out of or relating to this Agreement shall be submitted to arbitration in accordance with the arbitration provisions of the Employment Agreement.

(h) Counterparts. This Agreement may be executed in counterparts, and each counterpart, when executed, shall have the efficacy of a signed original. Photographic copies of such signed counterparts may be used in lieu of the originals for any purpose.
