3.    Vesting. Participant’s interest in the Restricted Stock shall be transferable and nonforfeitable (“Vested”) on the fifth anniversary of the Award Date (the “Vesting Date”). In addition, the Restricted Stock shall become Vested as of the date the Participant dies or becomes totally and permanently disabled (within the meaning of Code section 22(c)(3)) and the date of Participant’s death or disability shall be considered the Vesting Date for purposes of Sections 4 and 5 below.

4.    Forfeiture. All shares of Restricted Stock that are not then Vested shall be forfeited if (i) Participant’s employment with the Corporation or an Affiliate terminates prior to the date such shares have become Vested pursuant to Section 3 or (ii) Participant is no longer serving as an executive officer of the Corporation or an Affiliate on the Vesting Date.

5.    Shareholder Rights. Participant will have all the rights of a shareholder of the Corporation with respect to the Restricted Stock, including the right to receive dividends on and to vote the Restricted Stock; provided, however, that (i) Participant may not sell, transfer, pledge, exchange, hypothecate or otherwise dispose of the Restricted Stock, (ii) if the Restricted Stock is evidenced by a certificate, the Corporation shall retain custody of such certificate as provided in Section 6, and (iii) Participant will deliver a stock power in accordance with Section 7.

6.    Certificates.    At the option of the Corporation, the Restricted Stock shall be evidenced by an entry on the registry books of the Corporation or by a certificate issued by the Corporation. Participant may not receive or take possession of any shares of Restricted Stock through book-entry accounts held by, or in the name of, Participant so long as the Restricted Stock is not Vested. If the Restricted Stock is evidenced by a certificate, custody of such certificate evidencing the Restricted Stock shall be retained by the Corporation so long as the Restricted Stock is not Vested. Any book entries and certificates evidencing the Restricted Stock shall carry or be endorsed with a legend restricting the transferability of shares set forth in this Agreement. The Corporation shall release the restrictions on the book entry evidencing the Restricted Stock or deliver to Participant the stock certificates evidencing the Common Stock as soon as practicable after the Restricted Stock becomes Vested.
