10. RESTRICTED STOCK UNITS.

10.1 Awards of Restricted Stock Units. A Restricted Stock Unit (“RSU”) is an award to an eligible person covering a number of Shares that may be settled in cash, or by issuance of those Shares (which may consist of Restricted Stock) for services to be rendered or for past services already rendered to the Company or any Parent or Subsidiary. All RSUs shall be made pursuant to a RSU Agreement, which shall be in substantially a form (which need not be the same for each Participant) that the Committee has from time to time approved, and will comply with and be subject to the terms and conditions of the Plan.

10.2 Terms of RSUs. The Committee will determine the terms of a RSU including, without limitation: (a) the number of Shares deemed subject to the RSU; (b) the time or times during which the RSU may be exercised; (c) the consideration to be distributed on settlement, and the treatment of each RSU in the event of the Participant’s Termination. A RSU may be awarded upon satisfaction of such performance goals based on Performance Factors during any Performance Period as are set out in advance in the Participant’s

individual RSU Agreement. If the RSU is being earned upon satisfaction of performance goals, then the Committee will: (x) determine the nature, length and starting date of any Performance Period for the RSU; (y) select from among the Performance Factors to be used to measure the performance, if any; and (z) determine the number of Shares deemed subject to the RSU. Prior to settlement of any RSU earned upon the satisfaction of performance goals pursuant to a RSU Agreement, the Committee shall determine the extent to which such SAR has been earned. Performance Periods may overlap and participants may participate simultaneously with respect to RSUs that are subject to different Performance Periods and different performance goals and other criteria. The number of Shares may be fixed or may vary in accordance with such performance goals and criteria as may be determined by the Committee. The Committee may adjust the performance goals applicable to the RSUs to take into account changes in law and accounting and to make such adjustments as the Committee deems necessary or appropriate to reflect the impact of extraordinary or unusual items, events or circumstances to avoid windfalls or hardships.

10.3 Form and Timing of Settlement. The portion of a RSU being settled shall be paid currently. To the extent permissible under law, the Committee may also permit a Participant to defer payment under a RSU to a date or dates after the RSU is earned provided that the terms of the RSU and any deferral satisfy the requirements of Section 409A of the Code.
