  4. Total Direct Compensation

    | (2) As used in this Proxy Statement, “target TDC” is the executive’s base salary, target annual cash incentive, and grant date fair value (based on the value approved by the Compensation Committee and used to determine the number of shares subject to the award) of annual long-term incentive awards granted to the executive in 2025. In this Proxy Statement, we refer to an NEO’s target annual cash incentive, together with the grant date fair value (based on the value approved by the Compensation Committee and used to determine the number of shares subject to the award) of the NEO’s 2025 annual long-term incentive awards, as being “at risk” because the compensation is dependent upon performance and/or has a value dependent upon our stock price. In this Proxy Statement, we refer to an NEO’s target annual cash incentive, together with the grant date fair value (based on the value approved by the Compensation Committee and used to determine the number of shares subject to the award) of the portion of the NEO’s 2025 annual long-term incentive awards that include performance-based vesting requirements, as being “performance-based” compensation. |

  5. CORPORATE GOVERNANCE HIGHLIGHTS

  6. NOMINEES FOR DIRECTOR

    NOMINEES FOR DIRECTOR Upon the recommendation of the Governance Committee, the Board has nominated Angela M. Aman, Edward F. Brennan, PhD, Cia Buckley Marakovits, Daryl J. Carter, Jolie A. Hunt, David A. Kieske, Louisa G. Ritter, and Gary R. Stevenson for election to the Board for a term continuing until the annual meeting of stockholders to be held in 2027 and until their respective successors are duly elected and qualified. Peter B. Stoneberg will retire from his position on the Board on the date of the Annual Meeting, and therefore, has not been nominated for re-election. The Board intends to reduce the size of the Board to eight directors immediately following the Annual Meeting. As a result of the foregoing, stockholders may vote only with respect to the eight director nominees named in this proxy statement. Mses. Aman, Hunt and Ritter, Messrs. Carter and Stevenson and Dr. Brennan were previously elected to serve on the Board by our stockholders. Ms. Buckley Marakovits and Mr. Kieske were appointed to the Board in 2026 as part of our ongoing Board refreshment process and are standing for election by our stockholders for the first time. At the request of the Governance Committee, Korn Ferry (US) (“Korn Ferry”) conducted a comprehensive search process and identified each of Ms. Buckley Marakovits and Mr. Kieske as potential director nominees and assessed each of their candidacies. Each member of the Board, as well as a representative of Korn Ferry, interviewed Ms. Buckley Marakovits and Mr. Kieske, and Korn Ferry performed diligence and reference checks on Ms. Buckley Marakovits and Mr. Kieske, including engaging a third party to conduct a background check. The Board met to discuss the qualifications of Ms. Buckley Marakovits and Mr. Kieske and the results of Korn Ferry’s diligence searches and determined to approve Ms. Buckley Marakovits and Mr. Kieske’s nomination for election to the Board.

  30. BOARD COMPOSITION

    Each director nominee will be elected at the Annual Meeting if he or she receives a majority of the votes cast with respect to his or her election (that is, the number of votes cast “FOR” the nominee must exceed the number of votes cast “AGAINST” the nominee). However, the majority voting standard does not apply in a contested election where the number of director nominees exceeds the number of directors to be elected at an annual meeting of stockholders. In such circumstances, directors will instead be elected by a plurality of all the votes cast in the election of directors at the annual meeting at which a quorum is present. The election of directors at this Annual Meeting is not contested. Under Maryland law, if an incumbent director is not re-elected at a meeting of stockholders at which he or she stands for re-election, then the incumbent director continues to serve in office as a holdover director until his or her successor is elected. To address this “holdover” issue, our Bylaws provide that if an incumbent director is not re-elected due to his or her failure to receive a majority of the votes cast in an uncontested election, the director will promptly tender his or her resignation as a director, subject to acceptance by the Board. The Governance Committee will then make a recommendation to the Board as to whether to accept or reject the tendered resignation, or whether other action should be taken. The Board will act on the Governance Committee’s recommendation and publicly disclose its decision, along with its rationale, within 90 days after the date of the certification of the election results. THE BOARD UNANIMOUSLY RECOMMENDS A VOTE “FOR” EACH OF THE DIRECTOR NOMINEES.

    APPROVAL OF AMENDMENT AND RESTATEMENT OF 2006 INCENTIVE AWARD PLAN

  33. GENERAL

    | • | Significant Focus on Performance-Based Vesting Equity Awards. Three-quarters of the annual equity awards granted to our NEOs in 2025, 2024, and 2023 are subject to performance-based vesting requirements, with the vesting of the awards based on FFO Per Share, relative TSR (TSR Percentile Ranking), and Average Debt to EBITDA (or EBITDAre) Ratio measures (for a discussion of these terms, see “Description of Plan-Based Awards – Performance-Based RSUs below”). |

  34. GENERAL

    | • | Responsible Share Request Size. We believe that we are asking for enough shares to be able to continue to grant equity awards under the 2006 Plan until approximately 2028-2029 (as discussed on page 33). We want our stockholders to have the ability to regularly validate their support of our approach to equity awards. |

  35. SHARES AVAILABLE FOR AWARDS; LIMITS ON AWARDS

    | • | The maximum number of shares that may be delivered under the 2006 Plan since its adoption pursuant to options qualified as incentive stock options granted under the plan is 8,320,000 shares, of which none have been granted to date. |

  36. SHARES AVAILABLE FOR AWARDS; LIMITS ON AWARDS

    To the extent that an award terminates, expires, lapses for any reason, or is settled in cash, any shares subject to the award will again be available for the grant of awards pursuant to the 2006 Plan. Except with respect to awards of stock options and stock appreciation rights (or “SARs”), any shares of common stock tendered by an award-holder or withheld by the Company to satisfy the grant or exercise price or tax withholding obligations with respect to any award will again be available for the grant of new awards pursuant to the 2006 Plan. To the extent that shares are delivered pursuant to the exercise of a stock option or SAR granted under the 2006 Plan, the number of underlying shares as to which the exercise related count against the shares available for grant or issuance under the 2006 Plan, without regard to the number of shares actually delivered to the participant upon exercise of the award. The Company may not increase the applicable share limits of the 2006 Plan by repurchasing shares of common stock on the market (by using cash received through the exercise of stock options or otherwise).

  37. AWARDS

    AWARDS The 2006 Plan provides for the grant of incentive stock options, nonqualified stock options, restricted stock, stock appreciation rights, performance shares, performance stock units, dividend equivalents, stock payments, deferred stock, restricted stock units, profits interest units in the Operating Partnership, as described below, performance bonus awards and other incentive awards to eligible individuals. Stock Options Stock options, including incentive stock options, as defined under Section 422 of the Internal Revenue Code, and nonqualified stock options, may be granted pursuant to the 2006 Plan. The option exercise price of all stock options granted pursuant to the 2006 Plan will not be less than 100% of the fair market value of our stock on the date of grant. No incentive stock option may be granted to a grantee who owns more than 10% of our stock unless the exercise price is at least 110% of the fair market value at the time of grant. Notwithstanding whether an option is designated as an incentive stock option, to the extent that the aggregate fair market value of the shares with respect to which such option is exercisable for the first time by any optionee during any calendar year exceeds $100,000 (or the option otherwise fails to qualify as an incentive stock option), such option will be treated as a nonqualified stock option. Stock options may be exercised as determined by the plan administrator, but in no event after the tenth anniversary of the date of grant. However, in the case of an option granted to a person who owns more than 10% of our stock on the date of grant, such term will not exceed five years. Restricted Stock Awards of restricted stock may be granted under the 2006 Plan. Restricted stock will be subject to restrictions on transferability and other such restrictions as the plan administrator may determine, including, without limitation, limitations on the right to vote restricted stock or the right to receive dividends on the restricted stock. These restrictions may lapse separately or in combination at such times, pursuant to such circumstances, in such installments, or otherwise, as the plan administrator determines at the time of grant of the award or thereafter. Stock Appreciation Rights A SAR is the right to receive payment of an amount equal to the excess of the fair market value of a share of our stock on the date of exercise of the SAR over the fair market value of a share of common stock on the date of grant of the SAR. The plan administrator may issue SARs in such amounts and on such terms and conditions as it may determine, consistent with the terms of the 2006 Plan, except that SARs may not be exercised more than ten years after the applicable date of grant. The plan administrator may elect to pay SARs in cash, in common stock, or in a combination of cash and common stock. Other Awards Under the Plan The 2006 Plan provides that the plan administrator may also grant or issue performance shares, performance stock units, dividend equivalents, stock payments, deferred stock, restricted stock units, profits interest units, performance bonus awards, and other incentive awards or any combination thereof to eligible employees, consultants, and directors. The terms of each such grant or issuance will be set by the plan administrator in its discretion. The plan administrator may establish the exercise price or purchase price, if any, of any such award. Any such award will only vest or be exercisable or payable while the participant is an employee or consultant of the Company, the Operating Partnership, or the TRS or any of their subsidiaries, or a director of the Company or the TRS, except that the plan administrator may provide that such an award may vest or be exercised or paid subsequent to a termination of employment or service, as applicable, or following a change in control (as defined in the 2006 Plan) of the Company, or because of the participant’s retirement, death or disability, or otherwise. Payments with respect to any such award, other than profits interest units, will be made in cash, in common stock, or a combination of both, as determined by the plan administrator. Each award granted under the 2006 Plan will be subject to such additional terms and conditions as determined by the plan administrator and will be evidenced by a written award agreement.

  38. AWARDS

    Performance Shares. Awards of performance shares are denominated in a number of shares of our stock and may be linked to any performance criterion or criteria determined appropriate by the plan administrator, in each case on a specified date or dates or over any period or periods determined by the plan administrator. Performance Stock Units. Awards of performance stock units are denominated in units equivalent to shares of our stock and/or units of value, including dollar value of shares of our stock, and may be linked to any performance criterion or criteria determined appropriate by the plan administrator, in each case on a specified date or dates or over any period or periods determined by the plan administrator. Dividend Equivalents. Dividend equivalents are rights to receive the equivalent value (in cash or our stock) of dividends paid on our stock. They represent the value of the dividends per share paid by us, calculated with reference to the number of shares that are subject to any award held by the participant, provided that (1) dividend equivalent rights may not be granted in connection with an option or SAR granted under the 2006 Plan or any other award granted under the 2006 Plan, the value of which is based solely on an increase in the value of a share of our stock after the date of grant of the award, and (2) effective for dividends and dividend equivalents granted in connection with awards (other than those referred to in clause (1) as to which dividend equivalent rights may not be granted) granted after April 4, 2017 under the 2006 Plan, any such dividends and/or dividend equivalents will be subject to the same vesting conditions (if any) as the award to which they relate and will be subject to termination and forfeiture (to the same extent as the corresponding portion of the award to which they relate) if such vesting conditions are not satisfied. Stock Payments. Stock payments include payments in the form of our stock or options or other rights to purchase our stock, in each case made in lieu of all or any portion of the compensation that would otherwise be paid to the participant. The number of shares will be determined by the plan administrator and may be based upon specific performance criteria determined appropriate by the plan administrator, determined on the date such stock payment is made or on any date thereafter. Deferred Stock. Deferred stock may be awarded to participants and may be linked to any performance criteria determined to be appropriate by the plan administrator. Stock underlying a deferred stock award will not be issued until the deferred stock award has vested, pursuant to a time-based vesting schedule or upon the satisfaction of performance criteria set by the plan administrator. Unless otherwise provided by the plan administrator, recipients of deferred stock generally will have no rights as a stockholder with respect to such deferred stock until the time the vesting conditions are satisfied and the stock underlying the deferred stock award has been issued. Restricted Stock Units. Restricted stock units, or “RSUs,” may be granted to any participant in such amounts and subject to such terms and conditions as determined by the plan administrator. At the time of grant, the plan administrator will specify the date or dates on which the RSUs will become fully vested and nonforfeitable, and may specify such conditions (if any) to vesting as it deems appropriate. At the time of grant, the plan administrator will specify the maturity date applicable to each grant of RSUs which will be no earlier than the vesting date or dates of the award and may be determined at the election of the participant. On the maturity date, we will transfer to the participant one unrestricted, fully transferable share of our stock (or, if provided in the award, the cash value of a share of our stock at that time) for each RSU scheduled to be paid out on such date and not previously forfeited. The plan administrator will specify the purchase price, if any, to be paid by the participant to us for such shares of our stock. Profits Interest Units. To the extent authorized by the partnership agreement of the Operating Partnership, the 2006 Plan authorizes the grant of units in the Operating Partnership that are intended to constitute “profits interests” within the meaning of the Internal Revenue Code and published Internal Revenue Service guidance. Profits interests may only be granted to participants for the performance of services to or for the benefit of the Operating Partnership in the participant’s capacity as a partner in the Operating Partnership, in anticipation of the participant becoming a partner of the Operating Partnership, or as otherwise determined by the plan administrator, provided that the profits interest units would constitute “profits interests” within the meaning of the Internal Revenue Code, Treasury Regulations promulgated thereunder and any published guidance by the Internal Revenue Service. At the time of grant, the plan administrator will specify the number of profits interest units subject to the award, the purchase price, if any, of the units and the date and conditions on which the profits interest units will vest. The plan administrator may impose transferability restrictions and other restrictions upon profits interest units.

  39. NO REPRICING

    NO REPRICING In no case (except due to an adjustment to reflect a stock split or other event referred to under “Adjustments” below, or any repricing that may be approved by stockholders) will the 2006 Plan administrator (1) amend an outstanding stock option or stock appreciation right to reduce the exercise price or base price of the award, (2) cancel, exchange, or surrender an outstanding stock option or stock appreciation right in exchange for cash or other awards for the purpose of repricing the award, or (3) cancel, exchange, or surrender an outstanding stock option or stock appreciation right in exchange for an option or stock appreciation right with an exercise or base price that is less than the exercise or base price of the original award.

  40. ELIGIBILITY

    ELIGIBILITY Employees and consultants of the Company, the TRS, the Operating Partnership or their subsidiaries, and directors of the Company or the TRS, are eligible to be granted non-qualified stock options, restricted stock, stock appreciation rights, performance share awards, performance stock units, dividend equivalents, stock payments, deferred stock, RSUs, profits interest units, other incentive awards, and performance bonus awards under the 2006 Plan. Currently, approximately 241 officers and employees of the Company, the TRS and the Operating Partnership (including all of the Company’s NEOs), two consultants to the Company, the TRS, and the Operating Partnership, and each of the Company’s eight non-employee directors, are considered eligible under the 2006 Plan. However, in 2025 we granted awards under the 2006 Plan to only 56 officers and employees of the Company, the TRS or the Operating Partnership (including all of the Company’s NEOs), to no consultants, and to each of the Company’s non-employee directors in office following the 2025 annual meeting of stockholders. Only employees of the Company and its qualifying corporate subsidiaries are eligible to be granted options that are intended to qualify as “incentive stock options” under Section 422 of the Internal Revenue Code.

  41. ASSUMPTION AND TERMINATION OF AWARDS

    ASSUMPTION AND TERMINATION OF AWARDS Generally, and subject to limited exceptions set forth in the 2006 Plan, if the Company dissolves or undergoes certain corporate transactions such as a merger, business combination, or other reorganization or a sale of substantially all of its assets, the outstanding awards granted under the 2006 Plan will not automatically accelerate and become vested under the terms of the 2006 Plan as long as there is provision for the awards to be substituted for, assumed, or otherwise continued after the event. If there is no such provision for the awards to be substituted for, assumed, or otherwise continued after the event (that is, the awards are to be terminated in connection with the change in control event), the awards would generally become fully vested and, in the case of options, exercisable. The Administrator also has the discretion to establish other change in control provisions with respect to awards granted under the 2006 Plan.

  42. SPECIFIC BENEFITS UNDER THE 2006 PLAN

    SPECIFIC BENEFITS UNDER THE 2006 PLAN The Company has not granted any awards that are conditioned on stockholder approval of this Proposal No. 2. Except for the non-employee director awards discussed below, the Company is not currently considering any new award grants under the 2006 Plan and the number and type of awards that the Company may grant in the future under the 2006 Plan (within the express limits of the 2006 Plan, discussed above) is not determinable. If the proposed share increase for the 2006 Plan had been in effect in 2025, the Company expects that its award grants for 2025 would not have been different from those actually made in 2025 under the 2006 Plan. For more information regarding those awards, please see the following discussion and, for more detailed information on the awards granted to our NEOs during 2025, see the material under “Compensation Discussion and Analysis” below and the executive compensation tables under “Named Executive Officer Compensation Tables” below. Non-Employee Director Awards The Company is not currently considering any new award grants under the 2006 Plan except for the annual grants of RSUs to non-employee directors described under “Director Compensation” below. These annual grants are determined based on the closing price of our common stock on the date of the grant as described below. Assuming, for illustrative purposes only, that the price of the common stock used for the conversion of the dollar amount for the annual grants under the non-employee director program ($145,000) into shares was $29.67 (the closing price of a share of our common stock on March 2, 2026), the number of shares that would be allocated to the Company’s seven non-employee directors nominated for election to the Board as a group pursuant to the annual grant formula over the remaining seven-year term of the 2006 Plan (2026 through 2033) is approximately 239,467 shares. This figure represents the continuation of the current non-employee director equity awards for the seven non-employee director nominees over that seven-year period. The actual number of shares that we may issue depends on, among other future variables, the number of our non-employee directors from time to time, the price of our common stock on the applicable grant date that is used to convert the applicable grant-date value into a number of shares, and whether the Board changes the $145,000 grant date value or other aspects of our non-employee director compensation program in the future.

  44. AGGREGATE PAST GRANTS UNDER THE PLAN

    AGGREGATE PAST GRANTS UNDER THE PLAN As of March 1, 2026, awards covering 13,463,406 shares of our common stock had been granted under the 2006 Plan (including options covering 1,550,000 shares and other awards covering 11,913,406 shares). This number of shares includes shares subject to awards that expired or terminated without having been exercised and paid and became available for new award grants under the 2006 Plan, as well as shares that were withheld to cover the exercise price or tax withholding obligations in connection with an award and became available for new award grants under the 2006 Plan. This number of shares, as well as the number of shares subject to past awards and outstanding and unvested awards in the table below is presented as to performance-based vesting restricted stock and RSU awards based on the actual number of shares subject to the award that became eligible to vest based on performance during the applicable performance period, except as to any award with an open performance period, which are included based on the maximum number of shares subject to the award. The following table shows information regarding the distribution of all awards among the persons and groups identified below, option exercises, and restricted stock and RSUs vesting prior to that date, and option and unvested RSU holdings as of that date.

  46. EQUITY COMPENSATION PLAN INFORMATION

    EQUITY COMPENSATION PLAN INFORMATION For additional information on the Company’s equity compensation plans, please see “Equity Compensation Plan Information” on page 105 below.

  47. RECOMMENDATION

    | • | To provide an incentive to achieve key strategic, operational, and financial performance measures by linking short-term incentive award opportunities and a substantial portion of long-term incentive award opportunities to the achievement of specific performance objectives; |

  48. RECOMMENDATION

    | • | To provide a majority of target TDC for our NEOs in the form of long-term incentive equity awards; |

  49. RECOMMENDATION

    | • | To set total compensation to be competitive with the peer group companies identified on page 75, taking into account our active portfolio management strategy and the skill set required to implement that strategy; and |

  50. RECOMMENDATION

    | • | Annual Short-Term Incentives Based on Performance Measurement Framework. Annual short-term incentives (annual cash bonuses) are “at risk” because the amount awarded could range from 0% to 150% of the NEO’s target short-term incentive depending on Company performance. The Compensation Committee determined the 2025 annual short-term incentives for our NEOs based on a rigorous performance measurement framework, assessing the Company’s actual performance against pre-established operational and financial goals (including corporate social responsibility and sustainability goals). We also applied specific weightings to each performance measurement category, and used objective threshold and maximum payout levels, to reduce the degree of qualitative judgment applied in determining final payouts. Based on the Company’s performance (as reflected on pages 63-66), the Compensation Committee determined that the 2025 short-term incentives for our NEOs would be approximately 119.6% to 125.6% of their target payout levels. See “Short-Term Incentives — Decisions for 2025; 2025 Key Operating and Financial Goal Setting and Performance” on page 64 for more information about how the goals are set and the Company’s performance. |

  51. RECOMMENDATION

    | • | Majority of Target TDC is in the Form of Long-Term Incentives. The most significant component of each NEO’s total compensation opportunity is in the form of equity-based long-term incentives that vest over a three-year period. In 2025, approximately 65.3% of Ms. Aman’s (and approximately 55.7% of our other NEOs’) target TDC was in the form of equity-based long-term incentives. We believe equity compensation helps to align the interests of our NEOs with those of our stockholders. Annual long-term equity awards are “at risk” because the final award value depends on our stock price as well as continued service over the three-year vesting period, with three-quarters of our NEOs’ 2025 annual equity award values also being dependent upon our FFO per share performance, relative total shareholder return, and net debt to EBITDAre performance during a three-year performance period. Specifically, shares available to be earned were contingent on achievement of a threshold level of FFO per share for 2025. If that goal was achieved, vesting levels would be determined based on (i) the extent to which the threshold level of FFO per share for 2025 was exceeded, (ii) our TSR compared to other office-focused REITs over a three-year period (for 50% of the performance-based awards), and (iii) our average annual ratio of net debt to EBITDAre relative to pre-established goals over the three-year period (for the remaining 50% of the performance-based awards).(1) |

  52. RECOMMENDATION

    | • | Target TDC Set Taking into Account Market Pay Levels and Payouts are Linked to Performance. The Compensation Committee did not set 2025 target TDC levels at any specific percentile against our peer group. Rather, the Compensation Committee considered peer group compensation data for 2024, as well as the other factors noted below in the CD&A under “2025 Named Executive Officer Compensation”, to inform its decision-making process for 2025. In setting the 2025 compensation levels, the Compensation Committee also considered the following factors: |

  53. RECOMMENDATION

    | • | Active Portfolio Management Strategy in Highly Competitive Markets. Our business model requires an active portfolio management strategy (see “2025 Company Performance” beginning on page 59 for a summary of our 2025 activities). We believe implementing this strategy requires a broader skill set than those of companies whose executives focus primarily on managing cash flows of a more static portfolio. |

  54. RECOMMENDATION

    | • | Target TDC Realized Only if Goals Achieved. In 2025, approximately 71.1% of Ms. Aman’s (and approximately 64.8% of our other NEOs’) target TDC was performance-based. As noted above, the payout of our short-term incentives and performance-based equity awards depends on our actual performance and may be forfeited if threshold levels of performance are not achieved. |

  55. RECOMMENDATION

    | (1) Please see the discussion under “Named Executive Officer Compensation Tables — Description of Plan-Based Awards — Performance-Based RSUs” beginning on page 85 below for more information on determining our FFO per share, relative TSR, and average ratio of net debt to EBITDAre, and related adjustments, for purposes of these awards. |

  82. EXTENSIVE STOCKHOLDER ENGAGEMENT AND RESPONSE TO 2025 VOTE

    EXTENSIVE STOCKHOLDER ENGAGEMENT AND RESPONSE TO 2025 VOTE Stockholders have an opportunity to cast an advisory “Say-on-Pay” vote on our executive compensation program each year at our Annual Meeting. At the 2025 Annual Meeting, approximately 90% of the votes were cast in favor of our program as described in our annual proxy statement. The Compensation Committee believes this result indicates that stockholders generally approve of our executive compensation program, and the compensation arrangements for our NEOs in 2025 were generally consistent with their arrangements in 2024. When making future compensation decisions for our NEOs, the Compensation Committee will continue to consider the views that stockholders express through the annual Say-on-Pay votes and through direct communication between stockholders and our Chair, our Board, and our management. Based on feedback we received from stockholders following our 2024 annual meeting, our executive annual cash incentive program framework for 2025 included a liquidity ratio instead of a debt to EBITDA ratio for the balance sheet management category used under the program, as debt to EBITDA is taken into account in our annual equity awards. We also included goals specific to each individual within the individual performance category under the program. Additionally, under the terms of the performance-based RSUs awarded in 2025, the target TSR percentile ranking to achieve 100% vesting for the portion of the award subject to the TSR modifier was set at the 51st percentile (rather than the 50th percentile) of the applicable comparison group of companies. Since our 2025 annual meeting, we reached out to the holders of approximately 75% of our shares of common stock and offered meetings to solicit their input on a variety of topics, including market conditions, executive compensation, corporate strategy, board refreshment, and corporate governance practices. We met with each of the stockholders who accepted such request. Mr. Brennan, our Board Chair at the time and a member of the Compensation Committee, personally led nearly all of these meetings. The feedback we received regarding our executive compensation program was consistently positive, with stockholders expressing support for the significant performance-based aspects of the program and recent simplification of the performance metrics being utilized. A few stockholders again expressed a desire that, in the design of our annual equity awards with performance-based vesting requirements, (1) the one year FFO performance measurement period be extended to three years to align with the three year relative TSR and average net debt to EBITDAre ratio performance measurement periods utilized under the awards and to differentiate the long-term incentive program from the one year FFO measurement under our short-term incentive program, and (2) we place a greater emphasis on the three year relative TSR performance measure. As discussed in more detail in “Decisions for 2026” on page 73, we adopted these changes for the NEO annual equity awards granted in 2026.

  83. COMPENSATION PHILOSOPHY AND OBJECTIVES

    | • | To provide an incentive to achieve key strategic, operational, and financial performance measures by linking annual cash incentive award opportunities and a substantial portion of long-term incentive award opportunities to the achievement of specific performance objectives; |

  84. COMPENSATION PHILOSOPHY AND OBJECTIVES

    | • | To provide a majority of target TDC for our NEOs in the form of long-term incentive equity awards; |

  85. COMPENSATION PHILOSOPHY AND OBJECTIVES

    | • | To set total compensation to be competitive with peer group companies, taking into account our active portfolio management strategy and the skill set required to implement that strategy; and |

  86. DESIGN FEATURES OF THE 2025 EXECUTIVE COMPENSATION PROGRAM

    | • | Annual Short-Term Incentives Based on Performance Measurement Framework. Annual short-term incentives (annual cash bonuses) are “at risk” because the amount awarded could range from 0% to 150% of the NEO’s target short-term incentive depending on Company performance. The Compensation Committee determined the 2025 annual short-term incentives for our NEOs based on a rigorous performance measurement framework, assessing the Company’s actual performance against pre-established operational and financial goals (including corporate social responsibility and sustainability goals). We also applied specific weightings to each performance measurement category, and used objective threshold and maximum payout levels, to reduce the degree of qualitative judgment applied in determining final payouts. Based on the Company’s performance (as reflected on pages 63-66), the Compensation Committee determined that the 2025 short-term incentives for our NEOs would be approximately 119.6% to 125.6% of their target payout levels. See “Short-Term Incentives—Decisions for 2025; 2025 Key Operating and Financial Goal Setting and Performance” on page 64 for more information about how the goals are set and the Company’s performance. |

  87. DESIGN FEATURES OF THE 2025 EXECUTIVE COMPENSATION PROGRAM

    | • | Majority of Target TDC is in the Form of Long-Term Incentives. The most significant component of each NEO’s total compensation opportunity is in the form of equity-based long-term incentives that vest over a three-year period. In 2025, approximately 65.3% of Ms. Aman’s (and approximately 55.7% of our other NEOs’) target TDC was in the form of equity-based long-term incentives. We believe equity compensation helps to align the interests of our NEOs with those of our stockholders. Annual long-term equity awards are “at risk” because the final award value depends on our stock price as well as continued service over the three-year vesting period, with three-quarters of our NEOs’ 2025 annual equity award values also being dependent upon our FFO per share performance, relative total shareholder return, and net debt to EBITDAre performance during a three-year performance period. Specifically, shares available to be earned were contingent on achievement of a threshold level of FFO per share for 2025. If that goal was achieved, vesting levels would be determined based on (i) the extent to which the threshold level of FFO per share for 2025 was exceeded, (ii) our TSR compared to other office-focused REITs over a three-year period (for 50% of the performance-based awards), and (iii) our average annual ratio of net debt to EBITDAre relative to pre-established goals over the three-year period (for the remaining 50% of the performance-based awards). |

  88. DESIGN FEATURES OF THE 2025 EXECUTIVE COMPENSATION PROGRAM

    | • | Target TDC Set Taking into Account Market Pay Levels and Payouts are Linked to Performance. The Compensation Committee did not set 2025 target TDC levels at any specific percentile against our peer group. Rather, the Compensation Committee considered peer group compensation data for 2024, as well as the other factors noted below under “2025 Named Executive Officer Compensation”, to inform its decision-making process for 2025. In setting the 2025 compensation levels, the Compensation Committee also considered the following factors: |

  89. DESIGN FEATURES OF THE 2025 EXECUTIVE COMPENSATION PROGRAM

    | — | Active Portfolio Management Strategy in Highly Competitive Markets. Our business model requires an active portfolio management strategy (see “2025 Company Performance” beginning on page 59 for a summary of our 2025 activities). We believe implementing this strategy requires a broader skill set than those of companies whose executives focus primarily on managing cash flows of a more static portfolio. |

  90. DESIGN FEATURES OF THE 2025 EXECUTIVE COMPENSATION PROGRAM

    | — | Target TDC Realized Only if Goals Achieved. In 2025, approximately 71.1% of Ms. Aman’s (and approximately 64.8% of our other NEOs’) target TDC was performance-based. As noted above, the payout of our short-term incentives and performance-based equity awards depends on our actual performance and may be forfeited if threshold levels of performance are not achieved. |

  93. General Description

    General Description Our short-term incentives (annual cash bonuses) are provided to motivate and reward our employees for the achievement of annual operational and financial goals and other strategic objectives measured over the year. During the first quarter of each year, the Compensation Committee approves a performance measurement framework for that year and establishes a target short-term incentive amount for each NEO. This process typically begins prior to year-end, takes place over several months, and involves an on-going dialogue between the Chair of the Compensation Committee and our management team. In establishing the performance measurement framework, the Compensation Committee considers the Company’s business plan and outlook for the year, the Company’s bonus goals and actual performance for the completed year, and feedback received from stockholders. The Compensation Committee also receives input from its independent compensation consultant, who is involved throughout the process in advising the Compensation Committee on the general structure of the program, as well as the specific metrics and goals under consideration. The Compensation Committee selects the performance categories and metrics that it believes will most accurately assess the annual performance of the Company and its progress towards its strategic goals. The Compensation Committee assigns a weight to each of the performance categories and metrics and sets objective threshold, target, and maximum payout levels. The weightings and specific payout levels for each metric further reduce the degree of qualitative judgment applied in determining final payouts. Following the performance year, the Compensation Committee compares the Company’s actual performance results to the pre-established goals. The Compensation Committee also assesses each executive’s individual performance during the year. In making these determinations (other than as to our CEO’s individual performance), the Compensation Committee receives input from our CEO. The Compensation Committee then applies the weightings for each performance category and metric to determine the Company’s and the Executive’s overall achievement and applicable bonus payout percentages. The maximum amount that may be awarded to an NEO is 150% of the NEO’s target short-term incentive amount.

  94. Decisions for 2025; 2025 Key Operating and Financial Goal Setting and Performance

    Decisions for 2025; 2025 Key Operating and Financial Goal Setting and Performance In February 2025, the Compensation Committee determined that the NEOs’ respective 2025 target short-term incentive amounts (as a percentage of base salary) would remain the same as their target amounts for 2024. The 2025 target short-term incentive amount for each of our NEOs was as follows: $1,435,000 for Ms. Aman, $912,750 for Mr. Smart, $475,000 for Mr. Kuehling, $560,000 for Mr. Paratte, and $560,000 for Mr. Trencher. In developing the performance measurement framework for 2025, the Compensation Committee selected performance measures that it considers to be common measures of REIT performance. Management prepared a property-by-property budget for the Company’s portfolio and integrated those budget assumptions with the Company’s platform budget assumptions to create operational and financial goals directly tied to the Company’s business plan for 2025. The Compensation Committee then reviewed and approved the Company’s proposed 2025 operational and financial goals for inclusion in the performance measurement framework, described below. Historically, goals have generally been set at levels that were higher than the performance levels achieved in the prior year. However, for a variety of operational and financial reasons, the performance level in the prior year may not accurately reflect the difficulty of achieving the specified level of performance in the current year (for example, because of current market conditions, funding requirements, the level or timing of capital recycling activity, or required changes in accounting treatment). In these cases, the Compensation Committee may set performance goals at levels that are the same or lower than the performance results achieved in the prior year but at levels that, after considering the composition of the Company’s portfolio at the start of each year, the Compensation Committee believes are comparatively as, or more, rigorous. The 2025 executive annual cash incentive program framework included four categories, each specifically weighted: an operational and financial measurement category with three goals (including FFO Per Share, leased square footage in the operating portfolio, and leased square footage in the development portfolio, weighted 30%, 20%, and 10%, respectively, of the overall incentive opportunity), a balance sheet management measurement category (liquidity ratio, weighted 10% of the overall incentive opportunity), a corporate social responsibility and sustainability category (weighted 10% of the overall incentive opportunity), and an individual performance assessment (weighted 20% of the overall incentive opportunity). Each of the operational and financial measurement category’s three financial goals and the balance sheet management category goal included a pre-determined level of performance required in order to achieve the threshold, target, or maximum incentive payout for the portion of the awards corresponding to those goals. Based on shareholder feedback in recent years, the Compensation Committee replaced the net debt to adjusted EBITDA ratio measure that had been used in the 2024 program with the liquidity ratio measure so that the balance sheet management measure used in the executive annual cash incentive program would not be the same as the net debt to adjusted EBITDA ratio measure used under our performance-based RSUs. The following table shows the 2025 performance measurement framework and 2025 goals approved by the Compensation Committee in early 2025, as well as the Company’s actual 2025 performance.

  95. 2025 Performance Measurement Framework

    | | | | 2025 Goals | | | | | | Category | Metric | Weight | Threshold (50% payout) | Target (100% payout) | Maximum (150% payout) | 2025 Performance | Why It Is Important | | Operational and Financial | FFO Per Share(1): | 30% | $3.85 | $3.95(2) | $4.075 | $4.20 (Maximum – 150%) | Our operational and financial performance, including leasing productivity, demonstrates our ability to effectively manage our Class A portfolio. FFO is an earnings metric widely utilized by the REIT industry and indicates our ability to generate recurring profits excluding the effects of real estate depreciation and amortization, gains from sales, and impairments. | | | Leased SF – Operating Portfolio: | 20% | 1,300K | 1,600K | 2,000K | 1,455K(3) (Below Target – 75.8%) | | | | Leased SF – Development Portfolio: | 10% | 100K | 200K | 350K | 409K (Maximum – 150%) | | | Balance Sheet Management | Liquidity Ratio(4): | 10% | 1.0x | 1.5x | 2.0x | 1.94x (Below Maximum – 144%) | Prudently managing our balance sheet allows us to fund our ongoing operations and future growth opportunities. The liquidity ratio metric helps to prioritize efficient and effective capital raising based on the near- and medium-term financing needs of the Company. | | Corporate Social Responsibility and Sustainability | | 10% | In 2025, we continued efforts to embed accountability for the Company’s environmental, social, and governance (ESG) objectives within the executive team by setting specific ESG goals tailored to each executive officer. These ESG goals were intended to prompt focus on key areas where environmental sustainability, social responsibility, and good governance efforts can drive business value, such as leasing and tenant engagement, operational improvements, capital expenditure planning, development and construction, acquisition and disposition considerations, talent development, succession planning, employee communications, and enhanced controls for ESG data. | | | | Given the importance of these topics to our business, our tenants, our employees, and our stockholders, we maintain a focus on corporate social responsibility and sustainability. | | Individual Performance | | 20% | Individual performance is assessed by the Compensation Committee, with input from the CEO (except as to the CEO’s own award). | | | | Permits the Compensation Committee to assess each executive’s specific performance during the year, when balanced with the objective criteria above. We believe this provides the Compensation Committee with the flexibility to make distinctions among the executive team. |

  96. 2025 Performance Measurement Framework

    | (2) The target level of FFO Per Share for 2025 was set below the FFO Per Share level achieved for purposes of the Company’s 2024 short-term incentives due to anticipated (at the time the target was set) reductions in year-over-year occupancy and one-time non-recurring income recognized during 2024. Taking these circumstances into account at the time it established the goals, the Compensation Committee believed that the 2025 FFO goal would be appropriately challenging. |

  97. 2025 Performance Measurement Framework

    | (3) Excludes short-term leasing. Target leasing levels may vary from year to year (and may be less than the prior year’s actual leasing levels, as was the case in setting the 2025 targets) based on current market conditions and anticipated (at the time the time the targets are set) lease expirations during the year and the amount of other space available to lease (and, in the case of new developments, space available or anticipated to become available to lease during the year). |

  98. 2025 Performance Measurement Framework

    Long-Term Incentives We grant annual long-term incentives to our NEOs in the form of RSUs that vest over a three-year period. A portion of the RSUs awarded to certain members of our senior management team include performance-based conditions. Each RSU represents and is paid in one share of our common stock, subject to the satisfaction of applicable performance and vesting conditions, which further aligns the interests of our NEO with those of our stockholders. The NEOs do not have the right to vote or (with limited exceptions such as in connection with death or by court order in connection with a divorce) dispose of any RSUs prior to vesting. Each RSU is granted in tandem with a corresponding dividend equivalent right that entitles the NEO to be credited with additional RSUs upon the Company’s payment of dividends to stockholders if the dividend equivalent right is or was outstanding on the record date. Any such additional RSUs credited in respect of dividend equivalent rights are subject to the same performance and vesting terms as the underlying RSUs and vest (if at all) together with the underlying RSU to which they relate. In addition to annual equity awards, we occasionally make grants of equity awards at other times at the discretion of the Compensation Committee, such as in connection with the negotiation of an employment agreement, or the hiring or promoting of employees.

  99. Decisions for 2025

    | • | Three-quarters of our NEOs’ total annual equity award are RSUs subject to performance-based conditions (“performance-based RSUs”). The performance-based RSUs cliff vest, if and to the extent the performance goals are achieved, in one lump sum after the end of the three-year performance period. |

  100. Decisions for 2025

    | • | One-quarter of our NEOs’ total annual equity award are RSUs subject to time-based vesting conditions (“time-based RSUs”). The time-based RSUs vest ratably in annual installments over a three-year vesting period and vesting is generally subject to continued service through the applicable vesting date. |

  101. Decisions for 2025

    | • | Achievement of sustained longer-term performance of the Company’s share price using a relative TSR modifier that measures the Company’s performance against other office REIT competitors in a custom peer group informed by the Bloomberg REIT Office Property Index over the entire three-year vesting period (i.e., the TSR Percentile Ranking metric, which applies to the other 50% of the performance-based awards); and |

  102. Decisions for 2025

    | • | Creation of an additional retention incentive, as vesting is generally contingent on the NEO’s continued service through the end of the three-year vesting period. |

  103. 2025 Annual Equity Award Values

    2025 Annual Equity Award Values In February 2025, the Compensation Committee granted each NEO an annual equity award consisting of a number of time-based RSUs and a “target” number of performance-based RSUs, each expressed as a dollar value that was then converted into a number of RSUs based on our stock price on the date of grant. These dollar values are set forth in the chart below. The Compensation Committee determined that the aggregate dollar value for each NEO’s 2025 annual equity award was appropriate based on its consideration of the factors listed on page 62.

  104. 2025 Annual Equity Award Values

    | Named Executive | Time-Based RSUs(1) (25%) | Target Performance- Based RSUs(1) (75%) | Total Equity Award(1) | | Angela Aman | $1,062,500 | $3,187,500 | $4,250,000 | | Justin Smart | $687,500 | $2,062,500 | $2,750,000 | | Jeffrey Kuehling | $187,500 | $562,500 | $750,000 | | A. Robert Paratte | $425,000 | $1,275,000 | $1,700,000 | | Eliott Trencher | $330,000 | $990,000 | $1,320,000 | | (1) These amounts are the values approved by the Compensation Committee in February 2025 and converted into the corresponding number of RSUs (the number of RSUs at the “target” level of performance in the case of the performance-based RSUs) based on the closing price of the Company’s common stock on the date of grant of the awards and rounded up to the nearest whole share. For the accounting fair value of these awards as reflected in the Summary Compensation Table, please refer to footnote (1) to the Summary Compensation Table. | | | |

  105. 2025 Performance-Based RSUs

    2025 Performance-Based RSUs The 2025 performance-based RSUs vest when the Compensation Committee determines if, and to the extent, the performance conditions have been achieved by the Company. Such determination will be made by the Compensation Committee in the first quarter of 2028. The total number of 2025 performance-based RSUs that ultimately vest will be determined as follows:

  106. 2025 Performance-Based RSUs

    | 1. | The target number of performance-based RSUs granted to each NEO is first multiplied by an FFO (As Adjusted) Per Share modifier that ranges from 0% to 150% (and 0% to 175% in the case of Ms. Aman). This modifier is determined by the Company’s FFO (As Adjusted) Per Share for 2025 as shown in the table below (the number of RSUs resulting from this calculation is referred to as the “Banked Shares” subject to the award). |

  107. 2025 Performance-Based RSUs

    | FFO (As Adjusted) Per Share (for 2025)* | FFO (As Adjusted) Per Share Modifier* (for NEOs except Ms. Aman) | FFO (As Adjusted) Per Share Modifier* (for Ms. Aman) | | $4.075 or greater | 150% | 175% | | $3.95 | 100% | 100% | | $3.85 | 50% | 25% | | Less than $3.85 | 0% (complete forfeiture) | 0% (complete forfeiture) | | * Determined on a pro-rata basis between points | | |

    | 68 | PROXY STATEMENT | KILROY REALTY |

  109. 2025 Performance-Based RSUs

    The Banked Shares subject to the award are then subject to additional performance conditions as follows:

  110. 2025 Performance-Based RSUs

    | 2. | 50% of the Banked Shares are multiplied by a TSR Percentile Ranking modifier that ranges from 50% to 150% (and from 25% to 175% for Ms. Aman). This modifier is determined as shown in the table below based on the percentile ranking of the Company’s TSR for the three-year performance period (2025-2027) among the TSRs for the comparison group of companies. The companies included in the relative TSR comparison group for these awards are identified in the “Named Executive Officer Compensation Tables – Description of Plan-Based Awards – Performance-Based RSUs” section below. |

  111. 2025 Performance-Based RSUs

    | TSR Percentile Ranking* (2025-2027) — 50.0% Weight | TSR Modifier* (for NEOs except Ms. Aman) | TSR Modifier* (for Ms. Aman) | | 75th percentile or greater | 150% | 175% | | 51st percentile | 100% | 100% | | 25th percentile or lower | 50% | 25% | | * Determined on a pro-rata basis between points | | |

  112. 2025 Performance-Based RSUs

    For example, if the TSR Percentile Ranking is at the 51st percentile, then there is no modification up or down to the Banked Shares allocated to this metric. If the TSR Percentile Ranking is below the 51st percentile, then the Banked Shares allocated to this metric may be reduced by up to 75% for Ms. Aman’s award and by up to 50% for our other NEOs’ awards. If the TSR Percentile Ranking is greater than the 51st percentile, then the Banked Shares allocated to this metric may be increased by up to 75% for Ms. Aman’s award and by up to 50% for our other NEOs’ awards.

  113. 2025 Performance-Based RSUs

    | 3. | 50% of the Banked Shares are multiplied by an Average Net Debt to EBITDAre Ratio modifier that ranges from 50% to 150% (and from 25% to 175% for Ms. Aman). This modifier is determined as shown in the table below based on the Company’s Average Net Debt to EBITDAre Ratio for the three-year performance period (2025-2027) calculated in the manner described in the “Named Executive Officer Compensation Tables – Description of Plan-Based Awards – Performance-Based RSUs” section below. |

  114. 2025 Performance-Based RSUs

    | Average Net Debt to EBITDAre Ratio* (2025-2027) — 50.0% Weight | Average Net Debt to EBITDAre Ratio Modifier* (for NEOs except Ms. Aman) | Average Net Debt to EBITDAre Ratio Modifier* (for Ms. Aman) | | 6.5x or less | 150% | 175% | | 7.0x | 100% | 100% | | 7.5x or higher | 50% | 25% | | * Determined on a pro-rata basis between points | | |

  115. 2025 Performance-Based RSUs

    The FFO (As Adjusted) Per Share measure applies to the 2025 results only. This measure was selected as a performance metric because it is a financial measure commonly used by analysts and investors to evaluate a REIT’s operational and financial performance. If the threshold level of FFO (As Adjusted) Per Share shown above is not achieved, the entire award is forfeited with no opportunity to vest in future periods. The FFO (As Adjusted) Per Share level corresponding to the target level of performance (100% vesting) was set lower than the actual level of performance attained in 2024 due to anticipated (at the time the target was set) reductions in year-over-year occupancy and one-time non-recurring income recognized in 2024. Taking these circumstances into account at the time it established the goals, the Compensation Committee believed that the 2025 FFO goal would be appropriately challenging. The TSR Percentile Ranking over the three-year performance period modifier was included to further align the interests and potential rewards of our executives with total shareholder returns on a relative basis over a longer-term performance period. The Average Net Debt to EBITDAre Ratio modifier over the three-year performance period was included to further incentivize prudent and disciplined management of the Company’s balance sheet. By including a key leverage metric, the Company is limited, without negatively impacting compensation, in its ability to incur significant additional debt to fund growth and drive levered earnings.

  117. 2025 Performance-Based RSUs

    The increased up-side and down-side leverage applied to the TSR modifier and the Average Net Debt to EBITDAre Ratio modifier for the award to Ms. Aman, relative to the other NEOs, reflected her responsibility for the overall performance of the Company. Please see the discussion under “Named Executive Officer Compensation Tables — Description of Plan-Based Awards — Performance-Based RSUs” beginning on page 85 below for more information on determining FFO (As Adjusted) Per Share, TSR Percentile Ranking, Average Net Debt to EBITDAre Ratio, and related modifiers for purposes of these awards.

  118. 2025 FFO Performance Under 2025 Annual Equity Awards

    2025 FFO Performance Under 2025 Annual Equity Awards In February 2026, the Compensation Committee determined that the Company’s 2025 FFO (As Adjusted) Per Share, when determined in accordance with the 2025 RSU award agreement, was $4.20. As a result, 150% (175% for Ms. Aman) of the target number of performance-based RSUs awarded in 2025 to the NEOs were “Banked Shares” and became eligible to vest, subject to (1) further adjustment as follows: (a) 50% of the Banked Shares will be adjusted (up or down) based on the Company’s relative TSR performance against other office REIT competitors included in the comparison group of companies over the three-year performance period and (b) 50% of the Banked Shares will be adjusted (up or down) based on the Company’s Average Net Debt to EBITDAre Ratio over the three-year performance period, and (2) in general, continued service through the three-year performance period.

  119. 2024 FFO Performance Under 2024 Annual Equity Awards

    2024 FFO Performance Under 2024 Annual Equity Awards In February 2024, the Compensation Committee awarded RSUs to the NEOs (other than Mr. Kuehling) that had a structure similar to the RSUs awarded in February 2025. The 2024 RSUs are described more fully in the Company’s proxy statement for the 2025 annual meeting of stockholders. In February 2025, the Compensation Committee determined that the Company’s 2024 FFO (As Adjusted) Per Share, when determined in accordance with the 2024 RSU award agreement, was $4.59. As a result, 150% (175% for Ms. Aman) of the target number of performance-based RSUs awarded in 2024 to the NEOs were Banked Shares and became eligible to vest, subject to (1) further adjustment as follows: (a) 50% of the Banked Shares will be adjusted (up or down) based on the Company’s relative TSR performance against other office REIT competitors included in the comparison group of companies over the three-year performance period and (b) 50% of the Banked Shares will be adjusted (up or down) based on the Company’s Average Net Debt to EBITDA Ratio over the three-year performance period, and (2) continued service through the three-year performance period.

  120. Performance Under 2023 Annual Equity Awards

    Performance Under 2023 Annual Equity Awards In February 2023, the Compensation Committee awarded RSUs to the NEOs (other than Ms. Aman and Mr. Kuehling) that had a structure similar to the RSUs awarded in February 2024 and February 2025. The 2023 RSUs are described more fully in the Company’s proxy statement for the 2024 annual meeting of stockholders. In February 2024, the Compensation Committee determined that the Company’s 2023 FFO (As Adjusted) Per Share, when determined in accordance with the 2023 RSU award agreement, was $4.74. Added back to reported FFO Per Share for purposes of this determination, and in accordance with the terms of the award agreements, were costs of $0.12 per share in 2024 related to the retirement of John Kilroy, our former Chief Executive Officer. As a result, 150% of the target number of performance-based RSUs awarded in 2023 to each NEO were Banked Shares and became eligible to vest, subject to (1) further adjustment as follows: (a) 50% of the Banked Shares will be adjusted (up or down) based on the Company’s relative TSR performance against other office REIT competitors included in the comparison group of companies over the three-year vesting period and (b) 50% of the Banked Shares will be adjusted (up or down) based on the Company’s Average Net Debt to EBITDA Ratio over the three-year performance period, and (2) continued service through the three-year performance period.

  122. Performance Under 2023 Annual Equity Awards

    In February 2026, the Compensation Committee made a final determination that 214.3% of the target number of performance-based RSUs awarded in 2023 to each NEO vested. The Compensation Committee’s final determination was based on (a) 150% of the target number of 2023 performance-based RSUs awarded to each NEO being Banked Shares as a result of the Company’s 2023 FFO (As Adjusted) Per Share performance, (b) a 135.7% adjustment with respect to 50% of the Banked Shares as a result of the Company’s relative TSR performance against other office REIT competitors included in the comparator group of companies (excluding Paramount Group Inc. as it was acquired during the performance period and excluded from the comparator group pursuant to the applicable award terms) over the three-year performance period being at the 71st percentile, and (c) a 150% adjustment with respect to 50% of the Banked Shares as a result of the Company’s 6.01x Average Net Debt to EBITDA Ratio over the three-year performance period (calculated as set forth in Appendix A). Additional Compensation Elements

  123. Stock Award Deferral Program

    Stock Award Deferral Program We maintain a Stock Award Deferral Program under which our directors and certain of our management employees, including our NEOs, may elect to defer payment of RSUs that would otherwise be made when the RSUs vest. Each deferred RSU represents the right to receive one share of our common stock in the future, subject in each case to the vesting conditions applicable to the award. In addition, deferred RSUs carry with them the right to receive dividend equivalents that credit participants, upon our payment of dividends in respect of the shares underlying the participant’s RSUs, with additional RSUs equal to the value of the dividend paid in respect of such shares. Shares of stock underlying vested RSUs will generally be paid to the participant on the earliest to occur of a change in control, the participant’s “separation from service” with us, the participant’s death or disability, or a pre-determined date, if specified by the participant. By electing to defer the payment of RSUs, participants are generally able to defer income taxes on these awards, which we believe helps us to attract, retain, and incentivize top talent without significant additional cost to the Company. Since RSUs are paid in our common stock and the deferral of payment of RSUs under the program results in participants holding RSUs for a longer period, we believe the Stock Award Deferral Program enhances the alignment between management and stockholder interests.

  124. Severance, Retirement, and Change in Control Arrangements

    Severance, Retirement, and Change in Control Arrangements We have entered into employment agreements with each of our NEOs (other than Mr. Paratte) that include certain severance benefits. In November 2025, the Compensation Committee adopted the Executive Severance Plan (as discussed in greater detail under page 94 below), and designated Mr. Paratte as a participant in the plan. The Compensation Committee also designated Mr. Smart, Mr. Kuehling, and Mr. Trencher as participants in the plan, in each case effective when the term of their employment agreement expires (March 1, 2026 as to the employment agreements with Messrs. Smart and Trencher, and March 1, 2027 as to the employment agreement with Mr. Kuehling). The Executive Severance Plan is designed to provide greater consistency between the severance protections afforded to certain eligible officers of the Company and to ensure that severance protections provided are consistent with current market practices. We do not provide our NEOs with any “single trigger” severance or equity award acceleration arrangements, meaning that severance benefits and accelerated vesting of equity awards are not triggered simply because a change in control occurs. Instead, time-based RSU awards granted to our NEOs generally vest in connection with a change in control only if the award is to be terminated (and will not be continued, substituted, or assumed) in connection with the transaction or if there is an involuntary termination of the award holder’s employment in connection with the transaction. In the case of the performance-based RSUs granted to our NEOs, performance is generally measured for the portion of the performance period through the date of the transaction, and the number of shares subject to the award based on that performance measurement become time-based RSUs with vesting subject to continued service through the original performance period (or accelerated vesting if the award is to be terminated or there is an involuntary termination of the NEO’s employment in connection with the transaction). In November 2025, the Compensation Committee also approved a policy for our NEOs and other key employees that provides for accelerated vesting of their equity awards (pro-rata vesting in the case of performance-based RSUs) upon their retirement if they meet certain age and service requirements. The Compensation Committee believes the adoption of a retirement policy was appropriate to facilitate orderly transitions of key management positions and help ensure similarly situated employees are treated equitably. For a description of the material terms of these arrangements, see “Named Executive Officer Compensation Tables — Employment Agreements — Salary and Short-Term Incentive (Annual Cash Bonus) Amounts,” “Named Executive Officer Compensation Tables — Grants of Plan-Based Awards — 2025,” “Named Executive Officer Compensation Tables — Description of Plan-Based Awards” and “Named Executive Officer Compensation Tables — Potential Payments Upon Termination or Change in Control” below.

  126. Severance, Retirement, and Change in Control Arrangements

    In February 2026, the Compensation Committee determined that the base salary, target annual cash incentive (as a percentage of base salary), and total equity award value for each of our NEOs for 2026 would remain the same as their 2025 levels, except that Ms. Aman’s base salary was increased by 3.7% for 2026, Mr. Kuehling’s base salary was increased by 5.3% for 2026, and the total equity award values for Ms. Aman and Mr. Trencher were increased. The Compensation Committee determined that these increases were appropriate to better align these executives’ compensation with market levels for their positions. The executive annual cash incentive program framework for 2026 will generally include the same four categories and weightings as the 2025 program: an operational and financial measurement category with three goals (including FFO (As Adjusted) Per Share, leased square footage executed in the operating portfolio, and leased square footage executed in the development portfolio, weighted 30%, 20%, and 10%, respectively, of the overall incentive opportunity), a balance sheet management category (liquidity ratio, weighted 10% of the overall incentive opportunity), a corporate social responsibility and sustainability category (weighted 10% of the overall incentive opportunity), and an individual performance assessment (weighted 20% of the overall incentive opportunity). Consistent with the 2025 structure, each of the operational and financial measurement category’s three goals, as well as the balance sheet category’s goal, will have a pre-determined level of performance required in order to achieve the threshold, target, or maximum incentive payout for the portion of the awards corresponding to those goals. The Compensation Committee determined that FFO (As Adjusted) Per Share will remain a performance measure under both our performance-based RSUs and our 2026 annual cash incentive program because we believe it is a critical measure of both our short-term and long-term success. However, the FFO (As Adjusted) Per Share measurement period under our performance-based RSUs will now be a three-year measure, as noted below. In addition, based on shareholder feedback and a review of current peer group practices, the terms of the performance-based RSUs awarded in 2026 were revised to include three distinct performance measures, with an initial number of shares eligible to vest to be determined based on our FFO (As Adjusted) Per Share over a three-year performance period (2026, 2027, and 2028), with that number of shares being adjusted up or down based 60% on our TSR Percentile Ranking over the three-year performance period and 40% on our Average Net Debt to EBITDAre Ratio over the three-year performance period, and with no portion of the awards vesting if our cumulative FFO (As Adjusted) Per Share over the three-year performance period is below a minimum threshold level. Measuring FFO (As Adjusted) Per Share over the three years in the performance period better aligns with the long-term nature of the awards and is different than the one-year FFO (As Adjusted) Per Share measure used in our executive annual cash incentive program framework. Increasing the emphasis on our TSR Percentile Ranking over our Average Net Debt to EBITDAre Ratio further emphasizes the link between award values, on the one hand, and shareholder returns and our TSR performance on a relative basis. In addition, we will only achieve the “target” vesting level associated with our TSR Percentile Ranking if we achieve a TSR Percentile Ranking of at least the 51st percentile. In addition, in order to more closely align Ms. Aman’s performance-based RSU award with the awards granted to other executives and current peer group practices, her 2026 award provides for a vesting percentage of 37.5% for performance at the threshold level (as compared with vesting at 50% for performance at threshold level under the other executives’ awards and at 25% under Ms. Aman’s 2025 award) and a vesting percentage of 162.5% for performance at the maximum level (as compared with vesting at 150% for performance at the maximum level under the other executives’ awards and 175% under Ms. Aman’s 2025 award; resulting in a maximum cumulative vesting of 264% for Ms. Aman’s 2026 award, as compared with maximum vesting of 225% for the other executives’ 2026 awards and 306.25% maximum vesting under Ms. Aman’s 2025 award).

  127. HOW WE MAKE COMPENSATION DECISIONS

    Role of Independent Compensation Consultant The Compensation Committee has sole authority to hire, retain, and terminate the services of independent compensation consultants to assist in its decision-making process. The Compensation Committee retained Korn Ferry as its independent compensation consultant in 2025 to provide advice regarding executive and director compensation. Korn Ferry performed a comprehensive review of our 2025 executive compensation program before it was established, including the composition of our peer group, amounts and nature of compensation paid to executive officers, structure of our various compensation programs, design of our short-term incentive performance measurement framework, performance vesting requirements for our annual long-term incentive awards, and appropriate target total direct compensation levels and potential payment and vesting ranges for our executive officers. Korn Ferry also provided data to the Compensation Committee on the compensation and relative performance of our peer group, reviewed certain peer group data, and reviewed drafts of the CD&A and related compensation tables for inclusion in the Company’s Proxy Statement filed in 2025. A representative of the Compensation Committee’s independent compensation consultant regularly attends meetings of the Compensation Committee and meets privately in executive session with the Compensation Committee to discuss its recommendations, at the Committee’s discretion. During 2025, Korn Ferry received $516,982 in fees for providing executive and director search services to the Company, and Korn Ferry received $202,500 for its services with respect to executive and director compensation described above. Korn Ferry had been engaged to provide certain ongoing executive and director search services to the Company before the Compensation Committee’s initial decision in 2023 to retain Korn Ferry to provide executive and director compensation consulting services to the Compensation Committee. However, the Compensation Committee was aware of the existing engagement with Korn Ferry at the time it engaged Korn Ferry as its compensation consultant, the members of the Compensation Committee are updated on the search services being provided by Korn Ferry, and, in performing its search services for the Company, Korn Ferry reports to the Board or one of its other committees. The decision to engage Korn Ferry to provide the executive and director search services was made by the Board or one of its other committees and, while the Board did not specifically approve Korn Ferry’s compensation for providing the search services, the Board (or applicable committee thereof) is informed as to the fees being provided to Korn Ferry to perform such services. The Compensation Committee has reviewed the other services provided by Korn Ferry and, after consideration of such services and other factors prescribed by the SEC for purposes of assessing the independence of compensation advisors, has determined that no conflicts of interest exist between the Company and Korn Ferry (or any individuals working on the Company’s account on Korn Ferry’s behalf). Role of Management in Executive Compensation Planning Our CEO provides evaluations of and recommendations regarding the compensation of our executive officers (other than for the CEO) to the Compensation Committee. Our CEO presents the overall results of the Company’s performance and achievement of historical and go-forward business objectives, and provides input on peer group selection and the design of the executive compensation program, from management’s perspective. Our CEO, CFO, and Chief Administrative Officer also collectively evaluate the financial implications and affordability of the Company’s compensation program. Each of our executive officers (including our NEOs) may periodically participate in the compensation process and in Compensation Committee meetings, at the invitation of the Compensation Committee, to advise on performance and/or activity in areas the executive may have particular knowledge or expertise, None of our NEOs otherwise had any role in determining the compensation of our NEOs. None of our NEOs are members of the Compensation Committee. Market Review and Compensation Peer Group The Compensation Committee reviews peer group data to assess the competitiveness of our executive compensation program and to help inform its decision-making process.

  128. HOW WE MAKE COMPENSATION DECISIONS

    When assessing the executive compensation peer group to be used for 2025, the Compensation Committee considered platform size, asset class, and geographic overlap, as well as our business’ forward-looking strategic priorities. With these perspectives in mind and with Korn Ferry’s input, the Compensation Committee continued to assess potential peer group companies based on factors such as financial alignment, office REIT focus, West Coast portfolio concentration, and each company’s focus on development of its properties. After consideration of these criteria, in December 2024, the Compensation Committee elected to maintain the existing peer group, which consists of the 14 publicly-traded REITs, for 2025 as highlighted in the table below.

  136. COMPENSATION GOVERNANCE PRACTICES

    Minimum Stock Ownership Guidelines As part of our compensation philosophy, we believe that our NEOs and our directors should hold a significant amount of the Company’s stock to help align their long-term interests with those of our stockholders. Accordingly, we maintain minimum stock ownership guidelines applicable to all of our NEOs, as reflected in the table below, and all of our directors, as described under “Director Compensation” below. Under the guidelines, each NEO has six years from the point of first being subject to the guidelines to satisfy the minimum guideline level of ownership. An NEO’s ownership that counts for purposes of the guidelines includes Company stock owned outright by the NEO, shares issuable in exchange for common limited partnership units of Kilroy Realty, L.P., shares held by the spouse or dependent children of the NEO, shares held in trust for the benefit of the NEO, the NEO’s spouse or dependent children, shares held by the NEO in a 401(k) plan account, and shares subject to the NEO’s outstanding RSU awards (with shares subject to performance-based RSU awards taken into account at the “target” level of performance). As of December 31, 2025, all of our NEOs had met the minimum required level of ownership (600% of base salary for Ms. Aman and 300% of base salary for all of our other NEOs), other than Mr. Kuehling, who has over five years remaining to attain the guideline level of ownership. Stock Holding Requirements Our stock ownership guidelines also provide that, if an executive falls short of the applicable level of stock ownership, the executive is expected to hold (and not sell) at least 50% of the net shares acquired upon exercise, vesting, or payment, as the case may be, of any equity award granted by us to the executive. “Net shares” for this purpose means the total number of shares acquired by the executive pursuant to the award, after reduction for shares having a fair market value equal to the exercise price of the award (in the case of stock options) and shares having a fair market value equal to the executive’s expected tax liability resulting from the award.

  141. SUMMARY COMPENSATION TABLE — 2023, 2024, AND 2025

    As discussed in the CD&A, in 2023, 2024, and 2025, the Company granted annual long-term incentive award RSUs to the NEOs, the vesting of which is subject, in part, to the Company’s performance. As required by applicable SEC rules, the accounting fair value of the performance-based RSUs awarded in these years was determined based on the probable outcome (determined as of the grant date of the awards, as the grant date of the awards is determined for accounting purposes) of the performance-based conditions applicable to the awards. For these purposes, we determined that, other than as to the Company’s TSR Percentile Ranking performance condition applicable to the awards, the “target” level of performance was the probable outcome of the applicable performance-based conditions as of the applicable grant date. Accordingly, for such portion of these awards, the accounting fair value is included for the NEOs as Stock Award compensation for the year in which the grant was made based on the “target” number of shares subject to the awards. For the portion of the performance-based awards that vest based on the Company’s TSR Percentile Ranking, the accounting fair value was included for the NEOs as Stock Award compensation for the year in which the grant was made based on a Monte Carlo simulation pricing model (which probability weights multiple potential outcomes) as of the grant date of the awards. For more information on the assumptions made in the Monte Carlo simulation pricing model, refer to Note 14 “Share-Based and Other Compensation” in the Notes to Consolidated Financial Statements in the Company’s Form 10-K for the year in which the awards were granted. Under the terms of the performance-based awards at grant, for awards granted in each of 2023, 2024, and 2025, between 0% and 225% (between 0% and 306.25% in the case of the awards granted to Ms. Aman) of the target number of shares subject to the awards can vest based on performance and the other vesting conditions applicable to the awards. The following tables present the fair value (determined as described above as of the grant date of the awards) of the annual long-term incentive performance-based RSUs awarded to the NEOs in 2023, 2024, and 2025 (to the extent compensation is shown in the Summary Compensation Table for the NEO for the year of grant of the award) under two sets of assumptions: (a) assuming that the target level of performance would be achieved as to the performance-based conditions other than the Company’s TSR Percentile Ranking, which we originally judged to be the probable outcome, and using the Monte Carlo simulation pricing model to value the portion of the awards that vest based on the Company’s TSR Percentile Ranking, and (b) assuming that the highest level of performance would be achieved (for awards granted in each of 2023, 2024, and 2025, 225% of the target level for awards other than the awards for Ms. Aman and 306.25% in the case of the awards granted to Ms. Aman).

    NONQUALIFIED DEFERRED COMPENSATION — 2025 The following table sets forth summary information regarding the contributions to and earnings on our NEOs’ deferred compensation balances during 2025, and the total deferred amounts for the NEOs as of December 31, 2025.

  178. NONQUALIFIED DEFERRED COMPENSATION — 2025

    | Name | Executive Contributions in Last FY ($) | Registrant Contributions in Last FY(1) ($) | Aggregate Earnings in Last FY(2) ($) | Aggregate Withdrawals/ Distributions ($) | Aggregate Balance at Last FYE(3) ($) | | (a) | (b) | (c) | (d) | (e) | (f) | | Angela Aman | — | — | — | — | — | | Justin Smart | 769,857 | 2,801,064 | 891,431 | — | 16,890,023 | | Jeffrey Kuehling | — | — | — | — | — | | A.

  179. NONQUALIFIED DEFERRED COMPENSATION — 2025

    | (1) The amount reported as registrant contributions in 2025 under column (c) includes each NEO’s RSUs that vested in 2025 but had not yet become payable, as described in the footnotes to the Option Exercises and Stock Vested table above for each executive. These RSUs are payable in shares of our common stock but, pursuant to the terms of each NEO’s deferral of the RSUs, payment does not occur until the applicable date as determined under our deferred compensation program. In accordance with applicable rules of the SEC, these RSUs are reflected in this table because, while the RSUs are considered to have been vested at the end of 2025, they had not yet become payable. The amounts reported as registrant contributions in the table above include stock-settled obligations with respect to the vested and deferred RSUs described above of $2,740,212 for Mr. Smart. The amounts reported as registrant contributions in the table above also include cash-settled obligations of $60,852 for Mr. Smart, $56,002 for Mr. Paratte, and $56,002 for Mr. Trencher, and are also included as 2025 compensation for the NEOs in the “All Other Compensation” column of the Summary Compensation Table. |

  180. NONQUALIFIED DEFERRED COMPENSATION — 2025

    | (2) The amount reported as aggregate earnings in 2025 under column (d) represents the change in value of cash-settled obligations and the change in value of each executive’s vested and deferred RSUs (based on the closing price of our common stock on December 31, 2025). No amounts reported in this column were reported as 2025 compensation for the NEOs in the Summary Compensation Table. |

  181. NONQUALIFIED DEFERRED COMPENSATION — 2025

    | (3) The balance at the end of 2025 under column (f) reflects amounts that were previously reported as compensation in the appropriate columns of the Summary Compensation Table for years through and including 2025 to the extent the executive was an NEO for the applicable year. These amounts include both cash deferrals and the grant date fair value of deferred RSUs for each NEO. The grant date fair value of the deferred RSUs assume target performance achievement and do not include any performance modification. Amounts reported in column (f) also include earnings credited on deferred amounts. In accordance with applicable SEC rules, these earnings have not been included in the Summary Compensation Table. |

  182. NONQUALIFIED DEFERRED COMPENSATION — 2025

    Deferrals of cash-settled compensation shown in this table are made under the Deferred Compensation Plan. Participant elections with respect to deferrals of compensation and distributions must generally be made in the year preceding that in which the compensation is earned, except that elections with respect to certain performance-based bonuses may be made as late as six months prior to the end of the applicable performance period (June 30th in the case of calendar-year performance period). In addition, newly eligible participants may be able to make deferral elections up to thirty days after they first become eligible to participate in the Deferred Compensation Plan, if later than the end of the year preceding that in which such deferred amounts will be earned. Participants may only change existing elections with respect to distributions if they satisfy certain requirements set forth in the Deferred Compensation Plan, including that they do so no later than twelve months prior to the first scheduled distribution and that they extend their deferral elections by at least five years. Participants are permitted to allocate (and reallocate) their cash-settled deferrals, as well as Company contributions and any notional earnings on either of the foregoing, amongst the investment alternatives made available by the Deferred Compensation Plan administrator for purposes of determining any notional gains or losses on participant account balances. The investment alternatives available under the Deferred Compensation Plan in 2025 consisted of a variety of publicly-available mutual funds with annual returns for 2025 ranging from 2.51% to 32.18%. Participants’ investment allocations are hypothetical only and do not give participants ownership interests in any actual assets of the Company or any trust funding obligations under the Deferred Compensation Plan; however, the Company may set aside assets to fund its obligations under the Deferred Compensation Plan in a limited (“rabbi”) trust, subject to the claims of the Company’s creditors in the event of the Company’s bankruptcy or insolvency.

    Participants may elect to receive distributions of their accounts (other than distributions of Company contributions) (i) while still in the service of the Company, in either a lump sum or in two to five annual installments occurring (or beginning) no earlier than two years after such amounts were earned, (ii) upon retirement from service, in a lump sum or up to fifteen annual installments (in certain cases, beginning no earlier than six months after retirement), or (iii) upon a change in control, in full. Participant elections may also provide for payment upon the earliest to occur of any two or more of the foregoing events (subject to the distribution limitations applicable to Company contributions). If a participant separates from service with the Company and its affiliates for any reason other than due to the participant’s death, disability, or retirement, the remaining balance of the participant’s account will generally be distributed in full (in certain cases, six months after the occurrence of such separation from service). In addition, a participant’s account balance will be distributed as soon as possible following the participant’s death or disability. All such separation, death, and disability distributions will be made without regard to any participant election(s).

  186. POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

    POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL The following section describes the benefits that may become payable to our NEOs in connection with a termination of their employment with the Company and/or a change in control of the Company as of December 31, 2025. Ms. Aman’s employment agreement generally provides that if her employment is terminated by the Company without “cause” or by Ms. Aman for “good reason” (as those terms are defined in her employment agreement), she will be entitled to receive the following payments and benefits (the “Aman Termination Benefits”): (i) accrued but unpaid compensation through the date of termination; (ii) payment of any bonus due for a fiscal year that ended prior to her separation date plus a pro-rata portion of her target bonus for the year in which her employment ends (pro-rata based on the number of days of employment during the year); (iii) cash severance pay equal to two times the sum of her annual rate of base salary and her target annual bonus opportunity (the “Aman Severance Payment”); (iv) payment or reimbursement of Ms. Aman’s premiums to continue healthcare coverage under COBRA for up to eighteen months after the date of termination, and (v) full vesting of the initial equity award granted pursuant to her employment agreement. If Ms. Aman’s employment terminates due to her death or disability, she would be entitled to payment of any bonus due for a fiscal year that ended prior to her separation date plus a pro-rata portion of her target bonus for the year in which her employment ends. If such a termination of Ms. Aman’s employment by the Company without “cause” or by her for “good reason” occurs during the period within 60 days before a “Change in Control” (as defined in her employment agreement) of the Company or at any time after such a Change in Control, Ms. Aman will be entitled to receive the Aman Termination Benefits described above, except that the severance multiplier for the Aman Severance Payment would be “three” instead of “two” and she would be entitled to the following benefits: (i) as to each then-outstanding equity-based award granted by the Company to Ms. Aman that vests based solely on continued service with the Company, she will be entitled to accelerated vesting of the entire outstanding and unvested portion of the award; and (ii) as to each outstanding equity-based award granted by the Company to Ms. Aman that is subject to performance-based vesting requirements, any service-based vesting requirement under the award will be deemed satisfied in full but the performance-based vesting measurement will still apply and will be treated as provided in the applicable award agreement. The employment agreement requires Ms. Aman to sign a general release of claims in favor of the Company in order to receive benefits in connection with a termination of employment described above, other than accrued but unpaid compensation through the date of termination and other than in connection with a termination due to Ms. Aman’s death or disability. Mr. Smart’s employment agreement provided that, if his employment was terminated by the Company without “cause” or by Mr. Smart for “good reason” (as these terms were defined in his employment agreement), he would be entitled to receive the following payments and benefits (together with the Smart Severance Payment (as defined below), the “Smart Termination Benefits”): (i) accrued but unpaid compensation through the date of termination; (ii) in lieu of any annual incentive compensation, a partial year bonus based on actual performance against bonus targets as of the date of termination; (iii) full vesting of time-based equity awards; (iv) vesting of performance-based cash or equity awards (excluding outperformance incentive awards) as governed by the applicable plans, programs, and agreements, but (unless otherwise provided in an applicable award agreement) with the objectives of such awards deemed to be met at the greater of (a) target on the date of termination or (b) actual performance as of the date of termination and reasonably anticipated performance through the remainder of the year; (v) all payments due under any other compensatory or benefit plan, including any deferrals; and (vi) payment of the premiums charged for Mr. Smart, his spouse, and his eligible dependents to continue medical coverage under COBRA for two years after the date of termination. In addition, Mr. Smart would be entitled to receive a cash severance payment (the “Smart Severance Payment”) equal to the sum of (i) two times his annual base salary and (ii) two times the average of his two highest target “annual incentives” (that is, the sum of the short-term incentive award and the annual stock award (determined based on the target level of the award) as detailed in Mr. Smart’s employment agreement) during the three preceding full performance years.

  188. POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

    If Mr. Smart’s employment was terminated due to his death, he would be entitled to receive the Smart Termination Benefits described above, except that (i) his Smart Severance Payment described above would be determined using a multiplier of “one” instead of “two,” and (ii) the payment of the premiums to continue medical coverage under COBRA for Mr. Smart, his spouse, and his dependents, as applicable, would be for one year after the date of termination. If Mr. Smart’s employment was terminated due to his disability, he would be entitled to receive the Smart Termination Benefits described above, except that the payment of the premiums to continue medical coverage under COBRA for Mr. Smart, his spouse, and his dependents, as applicable, would be for one year after the date of termination. The employment agreement required Mr. Smart to sign a general release of claims in favor of the Company in order to receive benefits in connection with a termination of employment described above (including the Smart Severance Payment), other than accrued but unpaid compensation through the date of termination.
