(b)The restrictions described above shall commence on the date of this Agreement (the “Grant Date”) and, except as provided in Section 1(d) or Section 2, shall lapse with respect to one-third (33.3%) of the Units on the first anniversary of the Grant Date, one-third (33.3%) of the Units on the second anniversary of the Grant Date and with respect to the remaining Units on the third anniversary of the Grant Date.

(c)The number of shares of Common Stock covered by this award is equal to the number of Units.

(d)Absent a prior forfeiture, each Unit subject to this Agreement shall vest and shall represent the right to receive one share of Common Stock, and related dividends as described below, upon the expiration of the Restriction Period applicable to such Unit or, if earlier, upon a Change of Control as defined in the Plan or upon a waiver of the restrictions applicable to such Unit as described below in Section 2. The date on which a Unit vests is hereinafter referred to as the "Vesting Date."

2.Termination of Service.

If the Participant has a Termination of Employment (as defined on the Plan), all Units which are then subject to the restrictions imposed by Section 1 shall be forfeited and of no further effect; provided, however, that if the Participant ceases employment by reason of Retirement (as defined in the Plan) or involuntary termination, the Compensation Committee (the “Compensation Committee”) of the Company’s Board of Directors may waive all remaining restrictions.
