On each Vesting Date (as defined below) or as soon as practicable, but no later than sixty (60) days, thereafter, the Company shall deliver to the Participant one or more certificates representing the number of Shares equal to the number of RSUs that vested on such Vesting Date. Prior to settlement, the Participant shall make arrangements with the Company for the satisfaction of any federal, state, local or foreign withholding obligations that may arise in connection with such settlement in accordance with the terms of the Plan.

3.    Vesting of RSUs.

(a)    Vesting Schedule. One third (1/3^rd) of the RSUs shall vest on the Date of Grant, and thereafter, subject to the Participant’s continued Service on each Vesting Date, the remaining two-thirds (2/3^rd) of the RSUs shall vest in equal quarterly installments on each March 31, June 30, September 30 and December 31 of «Subsequent_Vesting_Yr_1» and

«Subsequent_Vesting_Yr_2» (each, a “Vesting Date”).

(b)    Acceleration.

(i)    In the event the Participant’s Service terminates due to death, Disability or Retirement, the unvested portion of the RSUs shall become fully vested and non-forfeitable on the date of such termination of Service.

(ii)    If, within one year following a Change in Control, the Participant’s Service is terminated by the Company without Cause or by the Participant with Good Reason, the unvested portion of the RSUs shall become fully vested and non-forfeitable on the date of the Participant’s termination of Service.

(c)    Termination of Service. If the Participant’s Service is terminated for any reason, other than as described in Section 3(b) above, the RSUs, to the extent not then-vested, shall be forfeited by the Participant without any consideration.

4.    Dividend Equivalents. With respect to each RSU the Participant shall have the right to receive an amount equal to the per Share dividend (if any) paid by the Company during the period between the Date of Grant and the RSU’s settlement, termination or forfeiture, subject to the remainder of this Section 4. When dividends are paid by the Company, the Participant shall be credited with an amount determined by multiplying the number of the Participant’s unvested RSUs by the dividend per Share, which amount shall be held by the Company and subject to forfeiture until the related RSUs vest in accordance with Section 3 hereof. Such dividends shall be paid to the Participant as soon as administratively practicable, but not later than sixty (60) days, following the settlement of the RSUs to which the dividends relate.

5.    No Right to Continued Service. The granting of the RSUs evidenced hereby and this Award Agreement shall impose no obligation on the Company or any Affiliate to continue the Service of the Participant and shall not lessen or affect any right that the Company or any Affiliate may have to terminate the Service of such Participant.

6.    Rights as a Stockholder. The Participant shall have none of the rights of a Stockholder of the Company unless and until the RSUs are settled for Shares.

If the Company deems it necessary to ensure that the issuance of Shares under the Plan is not required to be registered under any applicable securities laws, each Participant to whom such Shares would be issued shall deliver to the Company an agreement or certificate containing such representations, warranties and covenants as the Company may request which satisfies such requirements. The certificates representing the Shares shall be subject to such stop transfer orders and other restrictions as the Committee may deem reasonably advisable, and the Committee may cause a legend or legends to be put on any such certificates to

make appropriate reference to such restrictions.

23.    No Guarantees Regarding Tax Treatment. Participants (or their beneficiaries) shall be responsible for all taxes with respect to the RSUs. The Committee and the Company make no guarantees regarding the tax treatment of the RSUs. Neither the Committee nor the Company has any obligation to take any action to prevent the assessment of any tax under Section 409A of the Code or otherwise and none of the Company, any Subsidiary or Affiliate, or any of their employees or representatives shall have any liability to a Participant with respect thereto.

24.    Compliance with Section 409A. The Company intends that the RSUs be structured in compliance with, or to satisfy an exemption from, Section 409A of the Code and all regulations, guidance, compliance programs and other interpretative authority thereunder (“Section 409A”), such that there are no adverse tax consequences, interest, or penalties under Section 409A as a result of the RSUs. In the event the RSUs are subject to Section 409A, the Committee may, in its sole discretion, take the actions described in Section 12.1 of the Plan. Notwithstanding any contrary provision in the Plan or this Award Agreement, any payment(s) of nonqualified deferred compensation (within the meaning of Section 409A) that are otherwise required to be made under this Award Agreement to a “specified employee” (as defined under Section 409A) as a result of his or her separation from service (other than a payment that is not subject to Section 409A) shall be delayed for the first six (6) months following such separation from service (or, if earlier, the date of death of the specified employee) and shall instead be paid on the date that immediately follows the end of such six (6) month period or as soon as administratively practicable thereafter. A termination of Service shall not be deemed to have occurred for purposes of any provision of the Award Agreement providing for the payment of any amounts or benefits that are considered nonqualified deferred compensation under Section 409A upon or following a termination of Service, unless such termination is also a “separation from service” within the meaning of Section 409A and the payment thereof prior to a “separation from service” would violate Section 409A. For purposes of any such provision of this Award Agreement relating to any such payments or benefits, references to a “termination,” “termination of Service” or like terms shall mean “separation from service.”

IN WITNESS WHEREOF, the parties hereto have executed this Restricted Stock Unit Award Agreement as of the date first written above.
