The Company shall transfer the Vested Shares of Restricted Stock to an unrestricted account in the name of the Grantee as soon as practical after each Vesting Date.

2.3 In the event, prior to the Vesting Date, (i) Grantee dies while actively employed by the Company, or (ii) Grantee has his employment terminated by reason of Disability, any Restricted Stock shall become fully vested and nonforfeitable as of the date of Grantee’s death or Disability. The Company shall transfer the Shares of Restricted Stock, free and clear of any restrictions imposed by this Agreement (except for Section 3.4) to Grantee (or, in the event of death, to his surviving spouse or, if none, to his estate) as soon as practical after his date of death or termination for Disability.

2.4 In exchange for receipt of consideration in the form of the Restricted Stock award pursuant to this Agreement, the prospect of receiving such awards in the future, continued employment, and other good and valuable consideration, Grantee agrees that, in the event his employment with the Company is terminated, for the period set forth in the Exhibits attached hereto (the “Restricted Period”), Grantee shall comply with the non-competition, non-solicitation, non-recruitment, and non-disclosure restrictions attached hereto as Exhibits “A,” “B,” and “C ,” respectively (the “Restrictive Covenants”).

Moreover, in the event of any material change in corporate organization on the part of the Direct Competitors set forth in Exhibit A hereto, the parties agree to amend Exhibit “A” , as necessary, at the Company’s request, in order to reflect such change. Upon execution, any such written modification to Exhibit “A” shall represent an enforceable amendment to this Agreement and shall augment and supplant the definitions of the terms Executive Services or Direct Competitor set forth in Exhibit “A” hereto, as applicable.

2.5 Except for death or Disability as provided in Section 2.3 or as provided in Section 2.6, or except as otherwise provided in a severance agreement or change in control agreement with Grantee, if Grantee terminates his employment or if the Company terminates Grantee prior to the Vesting Date, the Restricted Stock shall cease to vest further, the unvested Shares of Restricted Stock shall be immediately forfeited, and Grantee shall only be entitled to the Restricted Stock that has vested as of his date of termination.
