(1) The fair value of the restricted stock awards are based upon the average of the high and low prices at which the Company’s common stock traded on the date of grant. The holders of time-vested restricted stock awards participate fully in the rewards of stock ownership of the Company, including voting and dividend rights. The holders of performance-based restricted stock awards do not participate in the rewards of stock ownership of the Company until vested. The holders of all restricted stock awards are not required to pay any consideration to the Company for the awards.

(2) These restricted stock grants will vest at the end of a five year period, or earlier if the director ceases to be a director for any reason other than cause, such as, for example, by retirement. If a non-employee director is removed from the Board for cause, the Company has ninety (90) days within which to exercise a right to repurchase any unvested portion of any restricted stock award from the non-employee director for the aggregate price of one dollar ($1.00).
