I.AMENDMENT OF EMPLOYMENT AGREEMENT

A.Section 1 of the Employment Agreement is hereby amended and restated in its entirety as follows:

1.       EMPLOYMENT DUTIES

(ii) The Corporation may pay Employee a discretionary annual bonus. The determination whether to pay and the amount of such bonus shall be made upon the recommendation of the Chief Executive Officer and by the approval of the Board of Directors.

C.Section 3(e) of the Employment Agreement is hereby amended and restated in its entirety as follows:

(e)       During the Term, Employee shall be entitled up to a maximum of five (5) paid personal days consistent with corporate policy.

D.Section 7(b) of the Employment Agreement is hereby amended and restated in its entirety as follows:

(b)       Upon termination by the Corporation pursuant to either subparagraph (i) or (iii) of paragraph (a) above or by Employee other than pursuant to subparagraph (iv) of paragraph (a) above, the Employee (or his estate in the event of termination pursuant to subparagraph (i)) shall be entitled to receive the Base Salary unpaid as of the date of termination including any personal days not taken.

E.Section 7(c) of the Employment Agreement is hereby amended and restated in its entirety as follows:

(c)       Upon termination by the Corporation without Just Cause or pursuant to subparagraphs (i), (ii) or (iv) of paragraph (a) above, then the term of the Agreement as set forth in Section 2 hereof shall be deemed to have been terminated as of such date and the Corporation shall pay to the Employee (or his estate in the event of termination pursuant to subparagraph (i)), (A) Base Salary unpaid as of the date of termination, including any personal days not taken, (B) severance equal to his annual rate of Base Salary in effect as of the date of termination payable at said rate in accordance with the Corporation’s payroll practices for a one month period (subject to set-off) (“Severance Pay”). Notwithstanding anything herein to the contrary, the Employee shall not be entitled to the Severance Pay unless he executes and delivers to the Corporation a general release of claims in such form as determined by the Corporation (the “Release”) and such Release becomes effective and irrevocable within sixty (60) days following the date of termination or resignation. Any Severance Pay required under this Section 7(c) shall commence on the first payroll date coincident or immediately following the sixtieth (60th) day following the Employee’s date of termination.

No unvested options shall vest beyond the termination date, except where previously noted in Section 3(b) or at the discretion of the Stock Option Plan Administrator. For purposes of payments under this Agreement that are subject to (and not exempt from) Section 409A of the Code that are payable upon the Employee’s “termination of employment,” such term shall instead mean “separation from service” within the meaning of Section 409A and the Treasury Regulations promulgated thereunder.
