1.Grant of Units. On the Grant Date, the Participant shall acquire, subject to the provisions of this Agreement, the number of Restricted Stock Units as specified in Award Summary (the “Units”). Each Unit represents a right at target, to receive on a date determined in accordance with this Agreement one (1) share of Stock. This Award shall be governed by the terms of the Plan, which are incorporated herein by this reference. The Participant acknowledges having received and read a copy of the Plan. Capitalized terms not otherwise defined by this Agreement will have the meanings assigned to the Plan.

2.No Monetary Payment Required. The Participant is not required to make any monetary payment (other than applicable tax withholding, if any, subject to Section 5 of this Agreement) as a condition to receiving the Units, or shares of Stock issued upon settlement of the Units, the consideration for which shall be past services actually rendered and/or future services to be rendered to the Company or for its benefit.

3.Vesting of Units. Subject to Participant’s continued employment through the Vest Date and other conditions described in the Award Summary (except as described under the heading “Special provisions regarding vesting of awards”), the Units will vest and become “Vested Units” as of the date set forth in the Award Summary.

a.    Issuance of Shares of Stock. The Company shall issue to the Participant on the Settlement Date (that is, the date on which the Units shall vest and become Vested Units) with respect to each Vested Unit to be settled on such date one (1) share of Stock. Shares of Stock issued in settlement of Units shall not be subject to any restriction on transfer other than any such restriction as may be required pursuant to Section 4.c. or Section 5 of this Agreement or the Company’s Insider Trading Policy. For purposes of this Agreement, “Insider Trading Policy” means the written policy of the Company pertaining to the sale, transfer or other disposition of the Company’s equity securities by members of the Board, officers or other

employees who may possess material, non-public information regarding the Company, as in effect at the time of a disposition of any Stock.

b.    Certificate Registration. A certificate for the shares as to which the Award is settled shall be registered in the name of the Participant, or, if applicable, in the names of the heirs of the Participant designated in writing by the Participant on forms approved by the Company for that purpose.

c.    Restrictions on Grant of the Award and Issuance of Shares. The grant of the Award and issuance of shares of Stock upon settlement of the Award shall be subject to compliance with all applicable requirements of federal, state or foreign law with respect to such securities. No shares of Stock may be issued hereunder if the issuance of such shares would constitute a violation of any applicable federal, state or foreign securities laws, or any other law or regulation, or the requirements of any stock exchange or market system upon which the Stock may then be listed.

a.    Tax Withholding in General. At the time this Agreement is executed, or at any time thereafter as requested by the Company, the Participant hereby authorizes withholding from any payroll and other amounts payable to the Participant, and otherwise agrees to make adequate provision for, any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company, if any, which arise in connection with the Award or the issuance of shares of Stock in settlement thereof. The Company shall have no obligation to deliver shares of Stock until the tax withholding obligations of the Company have been satisfied by the Participant.

b.    Assignment of Sale Proceeds; Payment of Tax Withholding by Check. Subject to compliance with applicable law and the Company’s Insider Trading Policy, the Participant shall satisfy the Company’s tax withholding obligations in accordance with procedures established by the Company providing for delivery by the Participant to the Company or a broker approved by the Company of properly executed instructions, in a form approved by the Company, providing for the assignment to the Company of the proceeds of a sale with respect to some or all of the shares being acquired upon settlement of Units. Notwithstanding the foregoing, the Participant may elect to pay by check the amount of the Company’s tax withholding obligations arising on any Settlement Date by delivering written notice of such election to the Company on a form specified by the Company for this purpose at least thirty (30) days (or such other period established by the Company) prior to such Settlement Date. By making such election, the Participant agrees to deliver a check for the full amount of the required tax withholding to the Company on or before the third business day following the Settlement Date. If the Participant elects to pay the required tax withholding by check but fails to make such payment

as required by the preceding sentence, the Company is hereby authorized, in its discretion, to satisfy the tax withholding obligations through any other means authorized by this Section 5, including by effecting a sale of some or all of the shares being acquired upon settlement of Units, withholding from payroll and any other amounts payable to the Participant, or by withholding shares in accordance with Section 5.c. of this Agreement.

c.    Withholding in Shares. The Company may, in its discretion, permit or require the Participant to satisfy all or any portion of the Company’s tax withholding obligations by deducting from the shares of Stock otherwise deliverable to the Participant in settlement of the Award a number of whole shares having a Fair Market Value, as of the date on which the tax withholding obligations arise, that the Company determines is up to the maximum amount that the Company is permitted by applicable law to withhold in respect of federal, state and local taxes, domestic or foreign, arising in connection with the Award or the issuance of shares of Stock in settlement thereof.

6.Effect of Change of Control on Award. In the event of a Change of Control, the Units shall be treated in accordance with Article 15 of the Plan. In the case of an Award that is subject to performance goals, notwithstanding any provision of the Plan, this Agreement or the Award Summary to the contrary, in the event of a Change of Control that occurs prior to the end of the Performance Period of the Award, the performance goals contained in the Award Summary shall no longer apply, effective as of the date of the Change of Control, and, instead, the achievement of such performance goals shall be deemed to have been met as of the Change of Control based on the Company’s performance as of immediately prior to the Change of Control, as determined by the Committee prior to the Change of Control. Except as provided in Article 15 of the Plan, any Units for which performance goals are deemed to have been met as of the Change of Control will remain outstanding as Time Based Units (as defined in the Award Summary) following the Change of Control.

7.Adjustments for Changes in Capital Structure. The Award shall be subject to adjustment in accordance with Section 4.4 of the Plan.

8.Rights as a Stockholder. The Participant shall have no rights as a stockholder with respect to any shares which may be issued in settlement of this Award until the Participant becomes the record holder of the shares of Stock underlying the Award. No adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date such certificate is issued, except as provided in Section 4.4 of the Plan.

9.Legends. The Company may at any time place legends referencing any applicable federal, state or foreign securities law restrictions on all certificates representing shares of Stock issued pursuant to this Agreement.

a.    Termination or Amendment. The Committee may terminate or amend the Plan or this Agreement at any time; provided, however, that (i) no such termination or amendment may materially impair the rights of a Participant under this Agreement without the consent of the Participant unless such termination or amendment is necessary to comply with applicable law, tax rules, stock exchange rules or accounting rules or the Company deems such termination or amendment to be necessary or desirable to avoid the imposition of taxes or penalties under Section 409A of the Code, and (ii) no such amendment may alter or accelerate the time or form of distributions in violation of Section 409A of the Code, if applicable, including, without limitation, any amendment that would violate the provisions of Section 409A of the Code requiring that any amendment to extend the issuance of any shares of Stock after the Settlement Date may not take effect until at least twelve (12) months after the date on which the new election is made, and, if the new election relates to a payment for a reason other than the death or disability of the Participant, the new election must provide for the deferral of issuance of such shares of Stock for a period of at least five (5) years from the Settlement Date such issuance of shares of Stock would otherwise have been made. No amendment or addition to this Agreement shall be effective unless in writing.
