Forfeiture of Performance Shares for Awards Not Timely Accepted. The grant of the Performance Shares is conditioned upon and subject to your accepting the Performance Shares by signing and delivering to the Company this Agreement, or otherwise electronically accepting the Performance Shares, no later than the first date the Performance Shares are scheduled to vest pursuant to this Agreement. In the event of your death or incapacitation prior to accepting the Performance Shares, the Company will deem the Performance Shares as being accepted. If you fail to accept the Performance Shares within the time described above, you will forfeit the Performance Shares.

Payment. Subject to the terms of the Plan, the Change in Control Agreement, and this Agreement, within 30 days after the following date (except as provided otherwise in Section 18 below), the Company shall make payment to you of the vested portion of the Performance Shares on such date (if any), less any vested Performance Shares previously paid to you (if any): September 26, 2020.

For purposes of this Agreement, “Tax-Related Items” means any or all income tax, social insurance tax, payroll tax, payment on account or other tax-related items that may be applicable to the Performance Shares by law or regulation of any governmental authority, whether federal, state or local, domestic or foreign. Regardless of any action the Company takes with respect to withholding Tax-Related Items, you acknowledge that you are ultimately responsible for all Tax-Related Items and that such Tax-Related Items may exceed the amount actually withheld by the Company or the Employer. You further acknowledge that the Company and/or the Employer (1) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Performance Shares, including, without limitation, the grant, vesting or payment with respect to the Performance Shares, the subsequent sale of Shares and the receipt of any dividends or dividend equivalents; and (2) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the Performance Shares to reduce or eliminate your liability for Tax-Related Items or to achieve any particular tax result. Furthermore, if you have become subject to tax in more than one jurisdiction between the Grant Date and the date of any relevant taxable event, you acknowledge that the Company and/or the Employer (or former Employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

Prior to any relevant taxable or tax withholding event, as applicable, you will pay or make adequate arrangements satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items. If permissible under local law and at your election, the Company will satisfy this condition pursuant to the withholding of Shares consistent with the “Share Withholding” provisions under section 14.2 of the Plan. The Company, in its discretion, may authorize alternative arrangements, including, if permissible under local law, the Company's selling or arranging to sell Shares that you acquire under the Plan. In any event, to the extent this condition is not otherwise satisfied, you authorize the Employer to withhold all applicable Tax-

Depending upon the withholding method, the Company or the Employer may withhold or account for Tax-Related Items by considering applicable minimum or maximum statutory withholding amounts or other applicable withholding rates. In the event Tax-Related Items are over-withheld, you will receive a refund in cash for any over-withheld amounts and will have no entitlement to the Shares equivalent. If the obligation for Tax-Related Items is satisfied by withholding of Shares, you shall be deemed, for tax purposes, to have been issued the full number of Shares, notwithstanding that a number of Shares is held back solely for the purpose of paying the Tax-Related Items due as a result of any aspect of your participation in the Plan.

You shall pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold or account for as a result of your participation in the Plan that cannot be satisfied by the means previously described. The Company may refuse to make payment with respect to the Performance Shares if you fail to comply with your obligations in connection with the Tax-Related Items.

Transfer of Performance Shares. The Performance Shares and any rights under any Performance Share may not be assigned, pledged as collateral or otherwise transferred, except as permitted by the Plan, nor may they be subject to attachment, execution or other judicial process. In the event of any attempt to assign, pledge or otherwise dispose of a Performance Share or any rights under a Performance Share, except as permitted by the Plan, or in the event of the levy of any attachment, execution or similar judicial process upon the rights or interests conferred by a Performance Share, the Committee may in its discretion terminate a Performance Share by notice to you.

You will have no rights as a shareholder with respect to any Shares issuable under the Performance Shares, including but not limited to voting rights or rights to dividends or dividend equivalents, until such Shares have been duly issued by the Company or its transfer agent pursuant to the vesting and payment of the Performance Shares.

In the event of a change in capitalization within the meaning of Section 4.4 of the Plan, the number and class of Shares or other securities that you are entitled to pursuant to this Agreement shall be appropriately adjusted or changed as determined by the Committee to reflect the change in capitalization, provided that any such additional Shares or additional or different shares of securities shall remain subject to the restrictions in this Agreement.

Termination of Service: For purposes of this Agreement, “Termination of Service” shall have the same meaning as “Termination of Employment” described in Section 9(n) of the Change in Control Agreement. Except as determined otherwise by the Committee or as provided in the Change in Control Agreement, you will not be deemed to have incurred a Termination of Service if the capacity in which you provide services to the Company changes (for example, you change from being a non-employee director to being an employee) or if you transfer employment among the various subsidiaries or affiliates of the Company constituting the Employer, so long as there is no interruption in your provision of services to the Company or other Employer as an employee or as a non-employee member of the Board of Directors of the Company.
