(a)           Vesting on Target Vesting Date.  If (i) the Participant remains in Continuous Service through and including the Target Vesting Date and (ii) the Measurement Price is equal to or exceeds $97.05, then the Participant shall become vested in a number of RSUs determined by multiplying the Target Amount by the applicable Vesting Factor.  All shares of Stock underlying the vested RSUs to be issued to the Participant under this Section 3(a), if any, shall be issued to the Participant within ten (10) days after the Target Vesting Date, but in any event, no later than March 15, 2013.

(e)           Termination During a Change in Control Period.  If (i) there is a Change in Control on or prior to the Target Vesting Date, (ii) the Participant’s Continuous Service is terminated by the Company other than for Cause or by the Participant on account of death or Disability during the Change in Control Period, and (iii) the Change in Control Closing Price is equal to or exceeds $97.05, then the Participant (or the Participant’s designated beneficiary in the event of the Participant’s death) shall become vested in a number of RSUs determined by multiplying the Target Amount by the applicable Vesting Factor.  Subject to Section 3(f), all shares of Stock underlying the vested RSUs to be issued to the Participant under this Section 3(e), if any, shall be issued to the Participant within ten (10) days after the termination of the Participant’s Continuous Service, but in any event, no later than March 15 of the calendar year following the calendar year in which the termination occurs.

(f)            Notwithstanding anything in this Agreement to the contrary, if the Participant is a “specified employee” (within the meaning of Section 409A of the Code) and if the issuance of the shares of Stock pursuant to Section 3(c) or 3(e) is considered to be a “deferral of compensation” (as such phrase is defined for purposes of Section 409A of the Code), then the Participant’s date of issuance of the shares of Stock shall be the date that is the first day of the seventh month after the date of the Participant’s “separation from service” with the Company (determined in accordance with Section 409A of the Code).

4.                                       Nontransferability of Grant

Except as otherwise provided herein or in the Plan, no RSUs shall be assigned, negotiated, pledged, or hypothecated in any way or be subject to execution, attachment or similar process.  No transfer of the Participant’s rights with respect to such RSUs, whether voluntary or involuntary, by operation of law or otherwise, shall be permitted.  Immediately upon any attempt to transfer such rights, such RSUs, and all of the rights related thereto, shall be forfeited by the Participant.

8.                                       Determinations

The Committee shall determine the extent to which an award has been earned, if at all, in accordance with Section 3 of this Agreement on or prior to the Target Vesting Date.  Such determination and all other determinations, interpretations or other actions made or taken pursuant to the provisions of this Agreement by the Committee or the Board in good faith shall be final, conclusive and binding for all purposes and upon all persons, including, without limitation, the Participant and the Company, and their respective heirs, executors, administrators, personal representatives and other successors in interest.  In addition, the Chairperson of the Committee is hereby authorized to make any determination with respect to an award’s vesting and payment in the event the Participant’s Continuous Service terminates pursuant to Sections 3(c) or 3(e) of this Agreement, and such determination shall be likewise conclusive and binding.

10.                                 Incorporation of the Plan

The Plan, as it exists on the date of this Agreement and as amended from time to time, is hereby incorporated by reference and made a part hereof, and the RSUs and this Agreement shall be subject to all terms and conditions of the Plan.  In the event of any conflict between the provisions of this Agreement and the provisions of the Plan, the terms of the Plan shall control, except as expressly stated otherwise.
