The Company may increase the Annual Base Salary paid to the Employee in an amount to be determined by the Chief Executive Officer of the Company. The Annual Base Salary shall be payable at such regular times and intervals as the Company customarily pays its employees from time to time.”

“Termination Stock Options and Restricted Stock. All of the outstanding unvested stock options and restricted stock granted to the Employee prior to termination will fully vest immediately upon termination, provided however, that any restricted stock that is still subject to performance based vesting at the time of such termination shall only vest when and to the extent the Compensation Committee of the Board certifies that the performance goals are actually met.”

     Except as otherwise specifically amended herein, the terms and provisions of the Employment Agreement remain in full force and effect. This Amendment may be executed in counterparts.
