The term “delivered to the Committee,” as used in this Plan, will include delivery to a person or persons designated by the Committee for the disbursement and the receipt of administrative forms.

Headings and subheadings are for the purpose of reference only and are not to be considered in the construction of this Plan. The pronouns “he,” “him” and “his” used in the Plan will also refer to similar pronouns of the female gender unless otherwise qualified by the context.

3.1Eligibility and Participation.

(a)Determination of Eligibility. It is intended that eligibility to participate in the Plan will be limited to Eligible Persons, as determined by the Committee, in its sole and absolute discretion. During the Open Enrollment Period, each Eligible Person will be contacted and informed that he may elect to defer portions of his Compensation and will be provided with an Election Form and such other forms as the Committee will determine. An Eligible Person will become a Participant by completing all required forms and making a deferral election during an Open Enrollment Period pursuant to Section 4.1. Eligibility to become a Participant for any Plan Year will not entitle an Eligible Person to continue as an Active Participant for any subsequent Plan Year.

(b)Eligibility on Initial Service. If an Eligible Person is elected to the Board during the Plan Year and designated by the Committee to be a Participant for such year, such Eligible Person may elect to participate in the Plan during the Special Enrollment Period for the remainder of such Plan Year, by completing all required forms under Section 4.1 and making an election pursuant to Article IV. Designation as a Participant for the Plan Year in which he is elected to the Board will not entitle the Eligible Person to continue as an Active Participant for any subsequent Plan Year.

(c)Loss of Eligibility Status. A Participant under this Plan who ceases to be a Director will continue as an Inactive Participant under this Plan until the Participant has received payment of all amounts payable to him under this Plan. In the event that an Eligible Person ceases active participation in the Plan because the Eligible Person is no longer described as a Participant pursuant to this Section 3.1, or because he ceases making deferrals of Compensation, the Eligible Person will continue as an Inactive Participant under this Plan until he has received payment of all amounts payable to him under this Plan.

4.1General Rules Regarding Deferral Elections. An Eligible Person may become a Participant in the Plan for the applicable Plan Year by electing during the Open Enrollment Period to defer his Compensation pursuant to the terms of this Section 4.1 on an Election Form. Such Election Form will be submitted to the Committee by the date specified by the Committee and will be effective with respect to Compensation deferral elections, as of the first payment dated on or after the next following January 1.

In the case of an Eligible Person who is newly elected to the Board during the Plan Year, the Election Form will be entered into within the Special Enrollment Period and submitted to the Committee by the date specified by the Committee and the specified deferral elections will only be effective with respect to Compensation earned after the date such Election Form is received by the Committee.

A Participant shall make a new deferral election with respect to each Plan Year. Each Election Form shall become irrevocable as of the last day of the Open Enrollment Period.

4.2Restricted Stock Unit Award Deferrals. Each Eligible Person may elect to defer receipt of all of the Shares and cash that would otherwise be issuable upon settlement of a Restricted Stock Unit award and any related Retained Distributions granted to such Participant during a Plan Year through the timely submission of an Election Form in accordance with Section 4.1. Deferrals of Shares and cash related to Restricted Stock Units and related Retained Distributions shall be credited to the Participant’s Equity Account and Retained Distribution Account, as applicable, as of the vesting date applicable to such Restricted Stock Units and related Retained Distributions, as set forth in the applicable Award Agreement.

Restricted Stock Units and Retained Distributions subject to a deferral election hereunder shall be subject to the same terms and conditions regarding vesting and forfeiture to which the Participant would have been subject had the Participant not elected to defer receipt of such Restricted Stock Units and Retained Distributions, including any vesting or forfeiture provisions included in the Equity Incentive Plan, the applicable Award Agreement or any other written agreement between such Participant and the Company or any of its subsidiaries (the “Applicable Agreements”). The portions of such Applicable Agreements that relate to the vesting and forfeiture of Restricted Stock Units and Retained Distributions subject to a deferral election hereunder are incorporated herein by reference.

Notwithstanding anything to the contrary in an Applicable Agreement, Restricted Stock Units and Retained Distributions subject to a deferral election hereunder shall be subject to the payment or settlement provisions set forth in the Plan, including all provisions of the Plan and, if applicable, a valid deferral election that relate to timing, form and medium of payment.

4.3Accounting for Deferred Compensation.

(a)Accounts. The Company shall establish and maintain an Account for each Participant. The Company may establish more than one Account on behalf of any Participant as deemed necessary by the Committee for administrative purposes.

(b)Equity Accounts, Retained Distribution Accounts and Other Distributions.

(i)Restricted Stock Units. On the date that a Restricted Stock Unit award subject to a deferral election hereunder vests in accordance with the terms and conditions of the Applicable Agreements, a number of notional Shares equal to the number of Shares that would otherwise have been issuable in settlement of such Restricted Stock Unit award shall be credited to a Participant’s Equity Account and shall become Elective Equity Deferrals. All Elective Equity Deferrals shall be notionally invested in Shares from the vesting date applicable to the Restricted Stock Units subject to a deferral election through the applicable Scheduled Payment Date.

(ii)Retained Distributions. In the event that the Company declares a dividend on the Shares, then on the payment date of the dividend, each Participant will be credited with Retained Distributions equal to the amount of the dividend per Share multiplied by the number of notional Shares credited to a Participant’s Equity Account as of the date of the dividend. Any such Retained Distribution shall be distributed on the Scheduled Payment Date applicable to the associated Restricted Stock Units that are subject to a deferral election pursuant to which the Retained Distributions are granted.

(iii)Notional Shares Subject to Adjustment. Notional Shares credited to a Participant’s Equity Account shall be subject to adjustment by the Committee in the same manner and under the same circumstances as would apply to outstanding Restricted Stock Units or Shares under the Equity Incentive Plan.

5.1In General. Except as otherwise provided in Sections 5.4 or 5.5, the Scheduled Payment Date set forth in the Election Form may include any of the following events:

(a)A specified future date;

(b)The Participant’s Separation from Service;

(c)An anniversary of the Participant’s Separation from Service;

(d)The occurrence of a Change in Control;

(e)An anniversary of the date on which the Elective Equity Deferrals would have otherwise vested;

(f)The Participant’s death; and

(g)The Participant’s Disability.

5.2Timing of Payments. Except as otherwise provided in this Article V, payments shall be made or commence on the Scheduled Payment Date.

5.3Medium of Payment. Benefit payments that are attributable to the Equity Account shall be paid in the form of Shares or cash, or any combination thereof, as determined by the Committee in its sole discretion, in accordance with the terms of the Award Agreement.

If the Equity Account is settled in Shares, each notional Share credited to the Equity Account on the Scheduled Payment Date shall represent the right to receive one Share. If the Equity Account is settled in cash, each notional Share credited to the Equity Account on the Scheduled Payment Date shall represent the right to receive cash in an amount equal to the Fair Market Value of a Share on the date of vesting.

Benefit payments that are attributable to the Retained Distribution Account shall be paid in the form of cash or, at the discretion of the Committee, in that number of Shares having an aggregate Fair Market Value on the date of vesting equal to the amount of the Retained Distributions credited to the Retained Distribution Account. Shares and cash delivered upon settlement of an Account shall be issued pursuant to the Equity Incentive Plan and subject to all of its terms and conditions.

5.4Unforeseeable Emergency. Upon application by the Participant, the Committee, in its sole and absolute discretion, may direct payment of all or a portion of the Participant’s Account balance prior to his Separation from Service and any scheduled withdrawal date in the event of an Unforeseeable Emergency. Any such application will set forth the circumstances constituting such Unforeseeable Emergency. The Committee will determine whether to grant an application for a distribution on account of an Unforeseeable Emergency in accordance with guidance issued pursuant to Section 409A of the Code. Specifically, the amount distributable on account of an Unforeseeable Emergency must be limited to the amount reasonably necessary to satisfy the need (plus any taxes resulting from the distribution). A distribution on account of an Unforeseeable Emergency may be made only to the extent that the Participant’s need cannot be met through insurance reimbursements, the liquidation of other assets (but only if such liquidation would not itself cause a hardship). However, the determination of an Unforeseeable Emergency is not required to take into account additional compensation that could be paid to the Participant, but which has not actually been paid, under any other nonqualified deferred compensation plan in which the Participant participates.

5.5Specified Employee Payment Delay. Unless otherwise payable without the imposition of penalty taxes pursuant to Section 409A of the Code, if a Participant is a “specified employee” within the meaning of Section 409A of the Code (a “Specified Employee”) as of the date of his or her Separation from Service, then no distribution of such Participant’s Account shall be made upon the Participant’s Separation from Service until the first payroll date of the seventh month following the Participant’s Separation from Service (or, if earlier, upon the date of the Participant’s death) (the “Specified Employee Payment Date”). Any payments to which a Specified Employee otherwise would have been entitled under the Plan during the period between the Participant’s Separation from Service and the Specified Employee Payment Date shall be accumulated and paid in a lump sum payment on the Specified Employee Payment Date.

6.1Legal Disability. If a person entitled to any payment under this Plan is, in the sole judgment of the Committee, under a legal disability, or otherwise is unable to apply such payment to his own interest and advantage, the Committee, in the exercise of its discretion, may direct the Company or payor of the benefit to make any such payment in any one or more of the following ways:

(a)Directly to such person;

(b)To his legal guardian or conservator; or

(c)To his spouse or to any person charged with the duty of his support, to be expended for his benefit and/or that of his dependents.

The decision of the Committee will in each case be final and binding upon all persons in interest, unless the Committee reverses its decision due to changed circumstances.

6.2Assignment. Except as provided in Section 6.1, no Participant or Beneficiary will have any right to assign, pledge, transfer, convey, hypothecate, anticipate or in any way create a lien on any amounts payable under this Plan. No amounts payable under this Plan will be subject to assignment or transfer or otherwise be alienable, either by voluntary or involuntary act, or by operation of law, or subject to attachment, execution, garnishment, sequestration or other seizure under any legal, equitable or other process, or be liable in any way for the debts or defaults of Participants and their Beneficiaries.

7.1Funding. Benefits under this Plan will be funded solely by the Company. Benefits under this Plan will constitute an unfunded general obligation of the Company, but the Company may, in its discretion, create reserves, funds and/or provide for amounts to be held in trust to fund such benefits on its behalf. Payment of benefits may be made by the Company, any trust established by the Company or through a service or benefit provider to the Company or such trust.

7.2Creditor Status. Participants and their Beneficiaries will be general unsecured creditors of the Company with respect to the payment of any benefit under this Plan, unless such benefits are provided under a contract of insurance or an annuity contract that has been delivered to Participants, in which case Participants and their Beneficiaries will look to the insurance carrier or annuity provider for payment, and not to the Company. The Company’s obligation for such benefit will be discharged by the purchase and delivery of such annuity or insurance contract.

8.1Plan Administration. The Plan shall be administered by the Committee.

8.2Duties of Committee. The Committee will have sole and absolute discretion regarding the exercise of its powers and duties under this Plan, including the following powers and duties:

(a)To direct the administration of the Plan in accordance with the provisions herein set forth;

(b)To adopt rules of procedure and regulations necessary for the administration of the Plan, provided such rules are not inconsistent with the terms of the Plan;

(c)To determine all questions with regard to rights of Participants and Beneficiaries under the Plan including, but not limited to, questions involving eligibility or the value of a Participant’s Accounts;

(d)To enforce the terms of the Plan and any rules and regulations adopted by the Committee;

(e)To review and render decisions respecting a claim for a benefit under the Plan;

(f)To furnish the Company with information that the Company may require for tax or other purposes;

(g)To engage the service of counsel (who may, if appropriate, be counsel for the Company), actuaries, and agents whom it may deem advisable to assist it with the performance of its duties;

(h)To prescribe procedures to be followed by Participants in obtaining benefits;

(i)To receive from the Company and from Participants such information as is necessary for the proper administration of the Plan;

(j)To establish and maintain, or cause to be maintained, the individual Accounts described in Section 4.3;

(k)To create and maintain such records and forms as are required for the efficient administration of the Plan;

(l)To make all determinations and computations concerning the benefits, credits and debits to which any Participant, or other Beneficiary, is entitled under the Plan;

(m)To give the Trustee of any trust established to serve as a source of funds under the Plan specific directions in writing with respect to:

(i)making distribution payments, giving the names of the payees, specifying the amounts to be paid and the time or times when payments will be made; and

(ii)making any other payments which the Trustee is not by the terms of the trust agreement authorized to make without a direction in writing by the Committee;

(n)To comply (or transfer responsibility for compliance to the Trustee) with all applicable federal income tax withholding requirements for benefit distributions, if applicable;

(o)To construe the Plan, in its sole and absolute discretion, and make equitable adjustments for any errors made in the administration of the Plan; and

(p)To adjust the notional Shares credited to a Participant’s Equity Account in the same manner and under the same circumstances as would apply to outstanding Restricted Stock Units and Shares under the Equity Incentive Plan.

The foregoing list of express duties is not intended to be either complete or conclusive, and the Committee will, in addition, exercise such other powers and perform such other

duties as it may deem necessary, desirable, advisable or proper for the supervision and administration of the Plan.

8.3Power and Authority of the Board of Directors. Notwithstanding anything to the contrary contained herein, the Board may, at any time and from time to time, without any further action of the Committee, exercise the powers and duties of the Committee under the Plan.

8.4Overpayment and Underpayment of Benefits. The Committee may adopt, in its sole and absolute discretion, whatever rules, procedures and accounting practices are appropriate in providing for the collection of any overpayment of benefits. If a Participant or Beneficiary receives an underpayment of benefits, the Committee will direct that payment be made as soon as practicable to make up for the underpayment. If an overpayment is made to a Participant or Beneficiary, for whatever reason, the Committee may, in its sole and absolute discretion, withhold payment of any further benefits under the Plan until the overpayment has been collected or may require repayment of benefits paid under this Plan without regard to further benefits to which the Participant or Beneficiary may be entitled.

9.1Continuation. The Company intends to continue this Plan indefinitely, but nevertheless assumes no contractual obligation beyond the promise to pay the benefits described in this Plan.

9.2Amendment of Plan. The Company, through an action of the Board, reserves the right in its sole and absolute discretion to amend this Plan in any respect at any time. No amendment may adversely impact the amount of benefits a Participant has accrued under the Plan at such time except to the extent required by applicable law.

9.3Termination of Plan. The Company, through an action of the Board, may terminate or suspend this Plan in whole or in part at any time, provided that no such termination or suspension will deprive a Participant, or person claiming benefits under this Plan through a Participant, of any amount credited to his Accounts under this Plan up to the date of suspension or termination, except as required by applicable law. Notwithstanding any provision of this Plan to the contrary, upon the complete termination of the Plan, the Board, in its sole and absolute discretion, may direct that the Committee treat each Participant as having incurred a Separation from Service and to commence the distribution of each such Participant’s Account to him or his Beneficiary, as applicable, to the extent that the commencement of such distribution will not violate Section 409A of the Code.

The Plan may be terminated and liquidated under the following circumstances:

(a)Corporate Dissolution or Bankruptcy. The Board may terminate and liquidate the Plan within twelve (12) months of a corporate dissolution taxed under section 331 of the Code or with the approval of a bankruptcy court pursuant to 11 U.S.C. § 503(b)(1)(A), provided that the amounts deferred under the Plan are included in Participants; gross incomes in the latest of the following years (or if earlier, the taxable year in which the amount is actually or constructively received):

(i)The calendar year in which the Plan termination and liquidation occurs.

(ii)The first calendar year in which the amount is no longer subject to a substantial risk of forfeiture.

(iii)The first calendar year in which the payment is administratively practicable.

(b)Change in Control. The Board may terminate and liquidate the Plan within the thirty (30) days preceding or the twelve (12) months following a change in control event, as defined in Treasury Regulation § 1.409A-3(i)(5)), provided that all plans or arrangements that would be aggregated with the Plan under Section 409A of the Code are also terminated and liquidated with respect to each Participant that experienced the change in control event so that under the terms of the Plan and all such arrangements the Participant is required to receive all amounts of compensation deferred under such arrangements within twelve (12) months of the termination of the Plan or arrangement, as applicable. In the case of a change of control event which constitutes a sale of assets, the termination of the Plan pursuant to this Section 9.3 may be made with respect to the Company that is primarily liable immediately after the change of control transaction for the payment of benefits under the Plan.

(c)Termination of Plan. The Board may terminate and liquidate the Plan provided that (i) the termination and liquidation does not occur by reason of a downturn of the financial health of the Company, (ii) all plans or arrangements that would be aggregated with the Plan under Section 409A of the Code are also terminated and liquidated, (iii) no payments in liquidation of the Plan are made within twelve (12) months of the date of termination of the Plan other than payments that would be made in the ordinary course operation of the Plan, (iv) all payments are made within twenty-four (24) months of the date the Plan is terminated and (v) the Company or the Company, as applicable depending on whether the Plan is terminated with respect to such entity, do not adopt a new plan that would be aggregated with the Plan within three (3) years of the date of the termination of the Plan.

10.1No Reduction of Company Rights. Nothing contained in this Plan will be construed as a right of any Director to be renominated to serve as a Director.

10.2Provisions Binding. All of the provisions of this Plan will be binding upon all persons who will be entitled to any benefit hereunder, their heirs and personal representatives.

10.3Section 409A of the Code. The Company intends that the Plan comply with the requirements of Section 409A of the Code and shall be operated and interpreted consistent with that intent. Notwithstanding the foregoing, the Company makes no representation that the Plan complies with Section 409A of the Code and shall have no liability to any Participant for any failure to comply with Section 409A of the Code. This Plan shall constitute an “account balance plan” as defined in Treas. Reg. section 31.3121(v)(2)-1(c)(1)(ii)(A). For purposes of Section 409A of the Code, all amounts

deferred under this Plan shall be aggregated with amounts deferred under other account balance plans.

IN WITNESS WHEREOF, this Plan has been executed on this 13th day of December, 2023.
