5.             Vesting Date.  The Restricted Stock shall become vested as follows: 50 shares of Restricted Stock shall vest on the first anniversary of the Grant Date; and 50 shares of Restricted Stock shall vest on the second anniversary of the Grant Date; provided that the Participant remains continuously employed by the Company through each such applicable vesting date.  Notwithstanding the foregoing, (i) in the event that the Participant’s employment is terminated on account of the Participant’s death or Disability at any time, all unvested shares of Restricted Stock not previously forfeited shall immediately vest on such date of termination and (ii) in the event of a Change in Control, all unvested shares of Restricted Stock not previously forfeited shall vest on such Change in Control.

Participant’s employment is terminated, the Award of Restricted Stock shall expire and such unvested shares of Restricted Stock shall immediately be forfeited on such date.

7.             Delays or Omissions.  No delay or omission to exercise any right, power, or remedy accruing to any party hereto upon any breach or default of any party under this Agreement, shall impair any such right, power or remedy of such party nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of any similar breach or default thereafter occurring nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring.  Any waiver, permit, consent or approval of any kind or character on the part of any party of any breach or default under this Agreement, or any waiver on the part of any party or any provisions or conditions of this Agreement, shall be in writing and shall be effective only to the extent specifically set forth in such writing.
