5.Non-transferability of Performance Shares; Limitation on Issuance of Shares. The Performance Shares are not transferable except by will or by the laws of descent and distribution, and may not be sold, assigned, pledged or encumbered in any way, whether by operation of law or otherwise. Following the Performance Period, certificates for the shares of Common Stock underlying the Actual Earned Shares may be issued during your lifetime only to you, except in the case of a permanent disability involving mental incapacity. Upon your death, any unissued shares of Common Stock underlying the Actual Earned Shares may be transferred to your legal representative as determined under applicable law, subject to the terms set forth in Section 7 of this Award Notice.

For purposes of this Award Notice, a “Qualifying Termination” means a termination of your Continuous Status as a Participant by reason of resignation or without Cause when:

(b) Notwithstanding the foregoing Section 7(a), if you provide Advance Notice of Intent to Retire, as defined below, and there is a termination of your Continuous Status as a Participant by reason of termination without Cause during the twelve (12) to thirty-six (36) month notice period following such Advance Notice of Intent to Retire, then you (or your legal representative, as applicable) will receive within 2.5 months after the end of the Performance Period, subject to the terms and conditions of the Plan, the Actual Earned Shares that you otherwise would have received had you remained in Continuous Status as a Participant with your Employer, the Company or one of its Subsidiaries during the entire Performance Period.

(i) Advance Notice of Intent to Retire. The Participant must provide at twelve (12) to thirty-six (36) months’ advance written notice to the Company of the Participant’s intent to retire. Such notice shall be provided to the Company’s Chief Human Resources Officer (or such other officer as the Committee may designate from time to time) and shall specify the general timeframe within which the Participant intends to retire. (Form attached in Addendum 2 of this document.)

(ii) Formal Notice of Commitment to Retire. The Participant must provide at least ninety (90) days’ advance written notice to the Company of the Participant’s commitment to retire, setting forth a formal retirement date. Such notice shall be provided to the Company’s Chief Human Resources Officer (or such other officer as the Committee may designate from time to time) and shall specify the exact date on which the Participant will retire. (Form attached in Addendum 2 of this document.)

(c) Upon termination of your Continuous Status as a Participant with your Employer, the Company or any of its Subsidiaries for reasons other than those described in Section 7(a) above, including termination for Cause, your Performance Shares shall be immediately canceled and forfeited. In such event, neither you nor any of your successors, heirs, assigns or personal representatives will thereafter have any further rights or interest in such shares or otherwise in this Award. For purposes of the foregoing, “Cause” shall have the same meaning as set forth in the Plan.

(a) Regardless of any action the Company or your Employer takes with respect to any or all income tax (including U.S. federal, state and local taxes and/or non-U.S. taxes), social insurance, payroll tax, fringe benefit tax, payment on account or other tax-related withholding (“Tax-Related Items”), you acknowledge that the ultimate liability for all Tax-Related Items legally due by you is and remains your responsibility and that the Company and your Employer: (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Performance Shares, including the grant of the Performance Shares, settlement or payment of the Performance Shares pursuant to the attainment of the performance objectives, and the subsequent sale of any shares of Common Stock acquired pursuant to the Performance Shares and the receipt of any dividends; and (ii) do not commit to structure the terms of the grant or any aspect of the Performance Shares to reduce or eliminate your liability for Tax-Related Items.

(b) Prior to the delivery of shares of Common Stock upon settlement or payment of the Performance Shares pursuant to the attainment of the performance objectives, if your country of residence (and/or your country of employment, if different) requires withholding of Tax-Related Items, the Company shall withhold a sufficient number of whole shares of Common Stock otherwise issuable under the Performance Shares that have an aggregate Fair Market Value sufficient to pay the Tax-Related Items required to be withheld. In cases where the Fair Market Value of the number of whole shares of Common Stock withheld is greater than the Tax-Related Items required to be withheld, the Company shall make a cash payment to you equal to the difference as soon as administratively practicable. The cash equivalent of the shares of Common Stock withheld will be used to settle the obligation to withhold the Tax-Related Items. Alternatively, the Company or your Employer may withhold the Tax-Related Items required to be withheld with respect to the shares of Common Stock in cash from your regular salary/wages, or from any other amounts payable to you. In the event the withholding requirements are not satisfied through the withholding of shares of Common Stock by the Company or through the withholding of cash from your regular salary/wages or any other amounts payable to you, no shares of Common Stock will be issued to you (or your estate) upon settlement or payment of the Performance Shares unless and until satisfactory arrangements (as determined by the Board of Directors) have been made by you with respect to the payment of any Tax-Related Items which the Company and your Employer determine, in their sole discretion, must be withheld or collected with respect to such Award. If you are subject to Tax-Related Items in more than one jurisdiction, you acknowledge that the Company or your Employer may be required to withhold or account for Tax-Related Items in more than one jurisdiction. By accepting the Performance Shares, you expressly consent to the withholding of shares of Common Stock and/or the withholding of cash from your regular salary/wages or other amounts payable to you as provided for hereunder.
