SECTION 1. General. The Participant named below has been granted an award of Restricted Shares (this “Restricted Stock Award”), subject to the terms and conditions set forth in the Plan, this Notice of Grant and the Restricted Stock Award Agreement attached hereto as Annex A (the “Restricted Stock Award Agreement”). The Restricted Shares shall be credited to a separate book-entry account maintained for the Participant on the books of the Company. The Participant shall not, with respect to any Restricted Share, make the election described in Section 83(b) of the Code without the prior written consent of the Company.

SECTION 2. Vesting. The Restricted Shares shall vest on the vesting dates as specified in this Section 2 (each such date, a “Vesting Date”), as follows: Twenty-five percent (25%) of the Restricted Shares shall vest on the one-year anniversary of the Grant Date and the remaining seventy-five percent (75%) of the Restricted Shares shall vest in thirty-six (36) equal monthly installments thereafter; provided that the Participant remains continuously in active employment or service with the Company or one of its Affiliates from the Grant Date through the applicable Vesting Date.

SECTION 3. Termination of Service. If, at any time prior to the final Vesting Date, the Participant’s employment or service with the Company and its Affiliates terminates for any reason (including any termination of employment or service by the Participant for any reason, or by the Company and its Affiliates with or without cause), then any unvested Restricted Shares shall be canceled and forfeited immediately and neither the Participant nor any of the Participant’s successors, heirs, assigns, or personal representatives, as applicable, shall thereafter have any further rights or interests in such unvested Restricted Shares.

SECTION 4. Change of Control. Upon the occurrence of a Change of Control, the Committee may, in its discretion and upon the satisfaction of any such conditions as the Committee may require, provide that any Restricted Shares held by the Participant, to the extent unvested or still subject to restrictions or forfeiture, will automatically be deemed vested and all restrictions and forfeiture provisions related thereto will lapse, as the case may be, as of immediately prior to such Change of Control and will be paid out (in cash, securities or other property) within 30 days following such Change of Control or such later date as may be required to comply with Section 409A of the Code, to the extent Section 409A of the Code is or is likely to become applicable to the Participant.
