Termination of Employment Prior to Vesting. Notwithstanding Section 3(a), the Participant’s Performance Awards (and any Performance Awards credited as dividend equivalents thereon) shall terminate to the extent that such Performance Awards have not become vested prior to the first date the Participant is no longer employed by the Corporation or one of its Subsidiaries, regardless of the reason for the termination of the Participant’s employment with the Corporation or a Subsidiary, subject to early vesting as provided in Sections 3(d) and 3(e). If the Participant is employed by a Subsidiary and that entity ceases to be a Subsidiary, such event shall be deemed to be a termination of employment of the Participant for the purposes of this Agreement (unless the Participant otherwise continues to be employed by the Corporation or another of its Subsidiaries following such event). c. Termination of Performance Awards. If any unvested Performance Awards are terminated under Section 3(b), such Performance Awards (and any Performance Awards credited as dividend equivalents thereon) shall automatically terminate and be cancelled as of the applicable termination date without payment of any consideration by the Corporation and without any other action by the Participant or the Participant’s beneficiary or personal representative, as the case may be. d. Early Vesting as a Result of Death, Disability or a Change in Control Event. Notwithstanding Section 3(a), the Participant’s Performance Awards (and any Performance Awards credited as dividend equivalents thereon), to the extent such Performance Awards are not then vested, shall either (i) become fully vested upon the termination of employment as a result of death or Total Disability of the Participant, or (ii) if Participant’s employment is terminated by the Corporation without Cause or the Participant terminates his or her employment for Good Reason upon or within twenty four months after the occurrence of a Change in Control Event, be deemed fully vested immediately prior to the first date the Participant is no longer employed by the Corporation. In the case of any inconsistency between this Section 3(d) and Section 5.2(c) of the Plan, this Section 3(d) shall control. e. Early Vesting if Attained Retirement Age. Notwithstanding Section 3(a), the Participant’s Performance Awards (and any Performance Awards credited as dividend equivalents thereon), to the extent such Performance Awards are not then vested, shall become fully vested upon the Participant attaining Retirement Age. 4. Determination of Performance Awards Payable.

5 a. Basis of Determination. The number of Performance Awards payable to the Participant (and any Performance Awards credited as dividend equivalents thereon) shall be determined on the basis of the extent to which the Performance Targets for each of the Performance Criteria have been achieved. The number of Performance Awards payable to the Participant shall be equal to the sum of the number of Performance Awards payable to the Participant with respect to each Performance Criteria, together with any dividend equivalents credited on such Performance Awards. The number of Performance Awards payable with respect to each Performance Criteria shall be equal to the Target Performance Award for such Performance Criteria multiplied by the Payout Percentages set forth in Exhibit A for such Performance Criteria, together with any dividend equivalents credited on such Performance Awards. b. Compensation Determination and Certification. As soon as practicable following the end of the Performance Period and, if applicable, the completion of the independent auditor’s report for the last year of the Performance Period, but in no event later than March 15 of the year following the end of the Performance Period, the Compensation Committee shall determine (i) the extent to which the Performance Targets for Performance Criteria are achieved, (ii) the Payout Percentages for each of the Performance Criteria and (iii) the number of Performance Awards (including any Performance Awards credited as dividend equivalents thereon) that have been earned, which determinations shall be made in accordance with Sections 7(b)(i) and 7(b)(iii), if applicable. For levels of achievement between target and zero and target and the maximum, the Compensation Committee shall determine the Payout Percentage by interpolation, to the extent not otherwise expressly set forth in subsection A, B, C or D of Exhibit A. c. Adjustments and Limitations. Notwithstanding the foregoing, the number of Performance Awards payable to the Participant (and the Performance Awards credited as dividend equivalents thereon) shall be subject to the adjustments, limitations, the Compensation Committee’s discretionary authority to make adjustments and other terms and conditions set forth in the Plan, provided that in no event may the maximum number of shares of Common Stock subject to this Award exceed 100,000. 5. Continuance of Employment. The vesting schedule requires continued employment or service through each applicable vesting date as a condition to the vesting of the applicable installment of the Award and the rights and benefits under this Agreement. Partial employment or service, even if substantial, during any vesting period will not entitle the Participant to any proportionate vesting or avoid or mitigate a termination of rights and benefits upon or following a termination of employment or services. Nothing contained in this Agreement or the Plan constitutes an employment or service commitment by the Corporation, affects the Participant’s status as an employee at will who is subject to termination without cause, confers upon the Participant any right to remain employed by or in service to the Corporation or Subsidiary, interferes in any way with the right of the Corporation or any Subsidiary at any time to terminate such employment or services, or affects the right of the Corporation or any Subsidiary to increase or decrease the Participant’s other compensation or benefits. Nothing in this paragraph, however, is intended to adversely affect any independent contractual right of the Participant without his or her consent hereto.

6 6. Dividend and Voting Rights. a. Limitation of Rights Associated with Performance Awards. The Participant shall have no rights as a shareholder of the Corporation, no dividend rights (except as expressly provided in Section 6(b) with respect to dividend equivalent rights) and no voting rights, with respect to the Awards and any Common Shares underlying or issuable in respect of such Awards until such Common Shares are actually issued to and held of record by the Participant. No adjustments will be made for dividends or other rights of a holder for which the record date is prior to the date of issuance of the Common Shares. b. Dividend Equivalents. The Participant shall be entitled to be credited with dividend equivalents in the form of additional Performance Awards with respect to the Awards credited to his or her Account as the Corporation declares and pays dividends in cash on its Common Shares. The number of Performance Awards to be credited to the Participant’s Account as a dividend equivalent will equal (1) the sum of the per share cash dividends paid by the Corporation on its Common Shares during the Performance Period multiplied by the number of Awards credited to the Participant’s Account on the last day of the Performance Period divided by (2) the average of the Fair Market Value of the Common Shares on each dividend payment date during the Performance Period. Performance Awards credited as dividend equivalents will become vested to the same extent as the Awards to which they relate. For purposes of clarity, no dividend equivalents shall be credited for a dividend record date with respect to any Awards that were paid or terminated prior to such dividend record date and the dividend equivalents will vest only if and to the extent that the underlying Performance Awards vest. 7. Xxxxxx and Manner of Distribution. a. General. On or soon as administratively practicable following the end of the Performance Period, but in no event later than March 15 of the year following the end of the Performance Period, the Corporation shall deliver to the Participant (or the Participant’s Beneficiary) a number of Common Shares equal to the number of Performance Awards subject to this Award that become vested on or prior to the end of the Performance Period (including any Performance Awards credited as dividend equivalents with respect to such vested Performance Awards), unless such Performance Awards terminate prior to such Installment Vesting Date pursuant to Section 3(b). b. Payment of Performance Awards upon Early Vesting as a Result of Death, Disability or Termination of Employment following a Change in Control Event. Notwithstanding Section 7(a): i. Upon termination of the Participant’s employment as a result of death of the Participant, the Corporation shall deliver to the Participant or his or her Beneficiary a number of Common Shares equal to the number of Performance Awards subject to this Award that become vested in accordance with Section 3 (including any Performance Awards credited as dividend equivalents with respect to such Performance Awards) as soon as administratively practicable following such termination of employment (but in no event later than 60 days following termination of employment or, to the extent applicable, the date specified in Section 7(e)). Notwithstanding anything to the contrary contained herein, the number of Common Shares payable under any Performance Award pursuant to this

7 Section 7(b)(i) shall be determined at an assumed result of performance with a Payout Percentage of 100% for each Performance Criteria (i.e., Payout as a Percentage of Target of 100%). ii. Upon termination of the Participant’s employment as a result of Total Disability of the Participant, the Corporation shall deliver to the Participant or his or her Beneficiary a number of Common Shares equal to the number of Performance Awards subject to this Award that become vested in accordance with Section 3 (including any Performance Awards credited as dividend equivalents with respect to such Performance Awards) as soon as administratively practicable following the end of the Performance Period (i.e., December 31, 2026) (but in no event later than March 15, 2027 or, to the extent applicable, the date specified in Section 7(e)). iii. Upon termination of Participant’s employment upon or within twenty four months after the occurrence of a Change in Control Event (A) by the Corporation without Cause or (B) by the Participant for Good Reason, in each case, then the Corporation shall deliver to the Participant a number of Common Shares equal to the number of Performance Awards vested in accordance with Section 3 (including any Performance Awards credited as dividend equivalents with respect to such Awards) as soon as administratively possible following his or her termination of employment (but in no event later than 60 days following termination of employment or, to the extent applicable, the date specified in Section 7(e)). Notwithstanding anything to the contrary contained herein, the number of Common Shares payable under any Performance Award pursuant to this Section 7(b)(iii) shall be determined at an assumed result of performance with a Payout Percentage of 100% for each Performance Criteria (i.e., Payout as a Percentage of Target of 100%). c. Termination of Performance Awards Upon Payment. A Performance Award will terminate upon the payment of that Performance Award in accordance with the terms hereof, and the Participant shall have no further rights with respect to such Performance Award. d. Form of Payment. The Corporation may deliver the Common Shares payable to the Participant under this Section 7 either by delivering one or more certificates for such shares or by entering such shares in book entry form, as determined by the Corporation in its discretion. e. Section 409A. Notwithstanding anything herein to the contrary, if the Corporation reasonably determines that the payment of Common Shares as a result of the Participant’s termination of employment is subject to Section 409A(a)(2)(B)(i) of the Code, such payment shall not be paid until the earlier of (i) six months after the Participant’s “separation from service” (within the meaning of Section 409A of the Code and Treasury Regulations Section 1.409A-1(h) without regard to optional alternative definitions available thereunder) and (ii) the Participant’s death. 8. Restrictions on Transfer. Neither the Award, nor any interest therein or amount or shares payable in respect thereof may be sold, assigned, transferred, pledged or otherwise disposed of, alienated or encumbered, either voluntarily or involuntarily. The transfer restrictions in the preceding sentence shall not apply to (a) transfers to the Corporation, (b) transfers by will or the

8 laws of descent and distribution, or (c) transfers pursuant to a QDRO order if approved or ratified by the Compensation Committee. 9. Adjustments Upon Specified Events. Upon the occurrence of certain events relating to the Corporation’s stock contemplated by Section 5.2 of the Plan, the Compensation Committee shall make adjustments if appropriate in the number of Performance Awards then outstanding and the number and kind of securities that may be issued in respect of the Award. 10. Tax Withholding. Upon the vesting and/or distribution of Common Shares in respect to the Performance Awards, the Corporation (or the Subsidiary last employing the Participant) shall have the right at its option to (a) require the Participant to pay or provide for payment in respect of cash of the amount of any taxes that the Corporation or any Subsidiary may be required to withhold with respect to such vesting and/or distribution, or (b) deduct from any amount payable to the Participant the amount of any taxes which the Corporation or any Subsidiary may be required to withhold with respect to such vesting and/or distribution. In any case where a tax is required to be withheld in connection with the delivery of Common Shares under this Agreement, the Compensation Committee may, in its sole discretion, direct the Corporation or the Subsidiary to reduce the number of shares to be delivered by (or otherwise reacquire) the appropriate number of whole shares, valued at their then Fair Market Value (with the “Fair Market Value” of such shares determined in accordance with the applicable provisions of the Plan), to satisfy such withholding obligation at the minimum applicable withholding rates. 11. Notices. Any notice to be given under the terms of this Agreement shall be in writing and addressed to the Corporation at its principal office to the attention of the Secretary, and to the Participant at the Participant’s last address reflected on the Corporation’s records, or at such other address as either party may hereafter designate in writing to the other. Any such notice shall be given only when received, but if the Participant is no longer an employee of the Corporation, shall be deemed to have been duly given by the Corporation when enclosed in a properly sealed envelope addressed as aforesaid, registered or certified, and deposited (postage and registry or certification fee prepaid) in a post office or branch office regularly maintained by the United States Government. 12. Plan. The Award and all rights of the Participant under this Agreement are subject to, and the Participant agrees to be bound by, all of the terms and conditions of the provisions of the Plan, incorporated herein by reference. In the event of a conflict or inconsistency between the terms and conditions of this Agreement and of the Plan, the terms and conditions of the Plan shall govern, except as otherwise provided expressly herein. The Participant agrees to be bound by the terms of the Plan and this Agreement. The Participant acknowledges having read and understood the Plan and this Agreement. Unless otherwise expressly provided in other sections of this Agreement, provisions of the Plan that confer discretionary authority on the Compensation Committee do not (and shall not be deemed to) create any rights in the Participant unless such rights are expressly set forth herein or are otherwise in the sole discretion of the Compensation Committee so conferred by appropriate action of the Compensation Committee under the Plan after the date hereof. Notwithstanding anything herein to the contrary, if pursuant to the terms of any written change in control or other agreement (the delivery of which has been authorized by the Board), between the Corporation (or any Subsidiary), on the one hand, and the Participant, on the other, the Participant’s Performance Awards hereunder would vest or become payable earlier or in a

9 manner other than as provided in this Agreement, then (subject to Section 7(e)) the terms of such change in control or other agreement shall control the vesting and payment thereof. 13. Entire Agreement. This Agreement and the Plan together constitute the entire agreement and supersede all prior understandings and agreements, written or oral, of the parties hereto with respect to the subject matter hereof. The Plan and this Agreement may be amended pursuant to Section 5.6 of the Plan. Such amendment must be in writing and signed by the Corporation. The Corporation may, however, unilaterally waive any provision hereof in writing to the extent such waiver does not adversely affect the interests of the Participant hereunder, but no such waiver shall operate as or be construed to be a subsequent waiver of the same provision or a waiver of any other provision hereof. 14. Limitation on Participant’s Rights. Participation in the Plan confers no rights or interests other than as herein provided. This Agreement creates only a contractual obligation on the part of the Corporation as to amounts payable and shall not be construed as creating a trust. Neither the Plan nor any underlying program, in and of itself, has any assets. The Participant shall have only the rights of a general unsecured creditor of the Corporation, with respect to amounts credited and payable, if any, with respect to the Performance Awards, and rights no greater than the right to receive the Common Shares as a general unsecured creditor with respect to such Awards, as and when payable hereunder. 15. Counterparts. This Agreement may be executed simultaneously in any number of counterparts, each of which shall be deemed an original but all of which together shall constitute one and the same instrument. 16. Section Headings. The section headings of this Agreement are for convenience of reference only and shall not be deemed to alter or affect any provision hereof. 17. Governing Law. This Agreement shall be governed by and construed and enforced in accordance with the laws of the State of California without regard to conflict of law principles thereunder. 18. Construction. It is intended that the terms of the Award will not result in the imposition of any tax liability pursuant to Section 409A of the Code. This Agreement shall be construed and interpreted consistent with that intent. 19. Recoupment. The Award under this Agreement and the Common Shares received by the Participant upon the vesting of the Award, or the value, proceeds or other benefits received by the Participant upon the sale of such Common Shares, shall be subject to the Corporation’s Policy Regarding the Recoupment of Certain Performance-Based Compensation Payments, as it may be amended from time to time, or as otherwise required by law or as may be necessary to enable the Corporation to comply with the rules of the New York Stock Exchange or the rules of any other national securities exchange or national securities association on which the securities of the Corporation or any of its subsidiaries may be listed.
