(b) In the event that Executive is not otherwise entitled to fully exercise all awards granted to him under any stock option or other compensation plan maintained by the Company and any such plan does not otherwise provide for acceleration of exercise ability upon the occurrence of the Change in Control described herein, such awards shall become immediately exercisable upon a Change in Control.

4. There shall be added a new Section 22 which reads in its entirety as follows:

22. 409A. The following provisions shall apply notwithstanding any other provisions herein to the contrary:

22.1 Separation From Service. Any amount that (i)is payable upon termination of Executive's employment with the Company under any provision of this Agreement, and (ii)is subject to the requirements of Code Section 409A, shall not be paid unless and until the Executive has Separated from Service. As used in this Agreement, the terms "Separated from Service" and "Separation from Service" shall have the·meaning specified in Treasury Regulation Section 1.409A-l(h).

22.2 Required Delay. If Executive is a "specified employee" (within the meaning of Section 409A(a)(2)(B)(i) of the Code) of Company at the time of his termination of employment and if payment of severance compensation to the Executive is on account of an "involuntary separation from service" (as defined in Treasury Regulation Section 1.409A-l (n)), Executive shall be paid such severance compensation during the six (6) month period immediately following the date of his Separation from Service as otherwise provided under Section 6 for such six-month period except that the total amount of such payments shall not

exceed the lesser of the amount specified under (i)Treasury Regulation Section 1.409A-1(9)(iii)(A)(l) or (ii)Treasury Regulation Section 1.409A-l(9)(iii)(A)(2). To the extent such amounts otherwise payable during such six-month period exceed the amounts payable under the immediately preceding sentence, such excess amounts shall not be paid during such six-month, period, but instead shall be paid in a single sum on the first regular payroll date of Company immediately. following the six (6) month anniversary of the date of Executive's Separation from Service. If Executive is a specified employee and Executive's Separation from Service is not an involuntary separation from service as defined in Treasury Regulation Section 1.409A-l(n), then any severance compensation and any other amount due to Executive under this Agreement that is subject to Code Section 409A and that would otherwise have been paid during the six (6) month period immediately following the date of Executive's Separation from Service shall be paid in a single sum on the first payroll date of Company immediately following the six month anniversary of Executive's Separation from Service. Amounts, the payment of which are deferred under this Section, shall be increased by interest at the prime rate as of the date of Executive's Separation from Service as published in the Wall Street Journal from the date such amounts would have been paid but for this provision and such accumulated interest shall also be paid to the Executive on the first payroll date of Company immediately following the six month anniversary of Executive's Separation from Service.

Notwithstanding the provisions of this Section 22, the Company has no responsibility or obligation to Executive with respect to any tax that may be incurred by Executive pursuant to Code Section 409A.


5.	Except as expressly amended pursuant to this Amendment, the Original Agreement shall continue in full force and effect without modification. Employee hereby waives any claim that this Amendment constitutes a Termination Other Than for Cause, as such term is defined in the Original Agreement.
