(e)Administrator Discretion. Notwithstanding anything contained in this Agreement to the contrary, subject to Article XIII of the Plan, the Administrator, in its sole discretion, may waive forfeiture provisions or accelerate the vesting with respect to any Restricted Stock Units under this Agreement, at such times and upon such terms and conditions as the Administrator shall determine; provided, however, that such waiver or acceleration of vesting shall not change the settlement date of the Restricted Stock Units provided in Section 3 of this Agreement.

(f)Post-Termination Informational Requirements. Before the settlement of any Restricted Stock Units following termination of employment or service, the Company may require the Participant (or the Participant’s Eligible Representative, if applicable) to make such representations and provide such documents as the Administrator deems necessary or advisable to determine whether the provisions of Section 2(b)(iii) or 2(d) apply. Such representations and documents may include tax returns and all other relevant information and records from which the Company can determine the current or former employment status of the Participant during the vesting period. Notwithstanding anything in this Agreement to the contrary, the settlement of the Restricted Stock Units may be withheld until information deemed sufficient by the Company is delivered to it, and any unvested Restricted Stock Units shall be forfeited if the requested information is not provided in sufficient detail to the Company before the earlier of (i) ninety (90) calendar days after the issue of a request from the Company for such information and (ii) December 31 of the calendar year in which the applicable Vesting Date occurs.

3.Settlement of Restricted Stock Units.

No fractional shares of Company Common Stock shall be issued in settlement of Restricted Stock Units. Fractional shares shall be rounded up to the nearest whole share; provided, that the Participant may not vest in more than the number of Restricted Stock Units specified in the Grant Notice.

Notwithstanding any other provision of this Agreement, the Participant may not sell the shares of Company Common Stock acquired upon vesting of the Restricted Stock Units unless such shares are registered under the Securities Act of 1933, as amended (the “Securities Act”), or, if such shares are not then so registered, such sale would be exempt from the registration requirements of the Securities Act. The sale of such shares must also comply with other applicable laws and regulations governing the shares and Participant may not sell the shares of Company Common Stock if the Company determines that such sale would not be in material compliance with such laws and regulations.

(b)No Rights as Stockholder. The Participant shall not have any rights as a stockholder including any voting, dividend or other rights or privileges as a stockholder of the Company with respect to any Company Common Stock corresponding to the Restricted Stock Units granted hereby unless and until shares of Company Common Stock are issued to the Participant in respect thereof.

(c)Dividend Equivalents. The Participant shall be credited with Dividend Equivalents in the form of a right to a cash payment when cash dividends are paid on the Company Common Stock. Such cash payment shall equal the amount obtained by multiplying the amount of the dividend declared and paid for each share of Company Common Stock by the number of Restricted Stock Units held by the Participant on the record date. Any cash amounts credited to the Participant’s account shall be paid to the Participant on the applicable payment date for the related cash dividends.

6.Participant’s Representations, Warranties and Covenants.

(a)No Conflicts; No Consents. The execution and delivery by the Participant of this Agreement, the consummation of the transactions contemplated hereby and the performance of the Participant’s obligations hereunder do not and will not (i) materially conflict with or result in

a material violation or breach of any term or provision of any Law applicable to either the Participant or the Restricted Stock Units or (ii) violate in any material respect, conflict with in any material respect or result in any material breach of, or constitute (with or without notice or lapse of time or both) a material default under, or require either the Participant to obtain any consent, approval or action of, make any filing with or give any notice to any Person as a result or under the terms of, any contract, agreement, instrument, commitment, arrangement or understanding to which the Participant is a party.

(c)Participant Status. The Participant represents and warrants that, as of the date hereof, the Participant is an officer, employee, director or Consultant of the Company or a Subsidiary.

7.Adjustment in Capitalization. The number, class or other terms of any outstanding Restricted Stock Units shall be adjusted by the Committee to reflect any stock dividend, stock split or share combination or any recapitalization, business combination, merger, consolidation, spin-off, exchange of shares, liquidation or dissolution of the Company or other similar transaction affecting the Company Common Stock in such manner as it determines in its sole discretion.

8.Tax Withholding. The Participant acknowledges that, regardless of any action taken by the Company or the Employer 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 benefits tax, payment on account or other tax-related items related to the Participant's participation in the Plan and legally applicable to the Participant (“Tax-Related Items”), the ultimate liability for all Tax-Related Items is and remains the Participant’s personal responsibility and may exceed the amount, if any, actually withheld by the Company or the Employer. The Participant further acknowledges that the Company and/or the Employer (a) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Participant’s participation in the Plan, including, but not limited to, the grant of Restricted Stock Units, the vesting of Restricted Stock Units, issuance or sale of shares of Company Common Stock, or the receipt of any dividends or Dividend Equivalents; and (b) do not commit to and are under no obligation to structure the terms of the Restricted Stock Units or any aspect of the Plan to reduce or eliminate the Participant’s liability for Tax-Related Items or achieve any particular tax result. Further, if the Participant is subject to Tax-Related Items in more than one jurisdiction, the Participant acknowledges 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, the Participant agrees to make arrangements satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items. In this regard, the Participant authorizes the Company and/or the Employer, or their respective agents, at their discretion, to satisfy their withholding obligations with regard to any Tax-Related Items by one or a combination of the following: (a) withholding from the Participant’s wages or other cash compensation payable to the Participant by the Company and/or the Employer, (b) withholding from proceeds of the sale of shares of Company Common Stock under the Plan, either through a voluntary sale or through a mandatory sale arranged by the

Company (on the Participant’s behalf pursuant to this authorization without further consent) to cover the Tax-Related Items required to be withheld, and (c) withholding in shares of Company Common Stock to be issued upon vesting of the Restricted Stock Units.

If the obligation for Tax-Related Items is satisfied by withholding in shares of Company Common Stock, for tax purposes, the Participant will be deemed to have been issued the full number of shares of Company Common Stock, notwithstanding that a number of the shares of Company Common Stock are held back solely for the purpose of paying the Tax-Related Items.

The Company or the Employer may defer the settlement of Restricted Stock Units until such withholding or other tax requirements are satisfied and if the Participant has not satisfied such withholding or other tax requirements as of the last day of the calendar year in which the Vesting Date occurs, the Restricted Stock Units shall be forfeited.

9.Nature of Grant. By accepting the Restricted Stock Units, the Participant acknowledges, understands and agrees that:

This Agreement is intended to be administered in a manner consistent with the requirements, where applicable, of Section 409A of the Code and the regulations promulgated thereunder (“Section 409A”). Where reasonably practicable, the Agreement shall be administered in a manner to avoid the imposition on the Participant of immediate tax recognition and additional taxes pursuant to Section 409A.

Notwithstanding the foregoing, the Company shall not have any liability to any Person in the event Section 409A applies to any payment hereunder in a manner that results in adverse tax consequences to the Participant or any of the Participant’s beneficiaries.

(m)Specified Employee Delay. If the Participant is deemed a “specified employee” within the meaning of Section 409A, as determined by the Committee, at a time when the Participant becomes eligible for settlement of the Restricted Stock Units upon his or her “separation from service” within the meaning of Section 409A, then to the extent necessary to prevent any accelerated or additional tax under Section 409A, such settlement will be delayed until the earlier of: (a) the date that is six months following the Participant’s termination of service and (b) the Participant’s death.
