Following the earlier of (1) the termination of Executive’s employment for any reason other than death (whether such termination is by the Company or the Executive) or (2) the closing of the Transaction (even if Executive remains employed following the Transaction) (the “Non-Compete Commencement Date”), Executive shall be subject to the non-competition covenant following the Non-Compete Commencement Date as provided in Section 9.2. In exchange for covenant, the Company shall pay to the Executive, in consideration for such covenant, an amount equal to sixty percent (60%) of the sum of (i) the Executive’s Base Salary at the rate in effect on the date of signing by Executive of this Amendment and (ii) the annual incentive bonus paid by the Company to the Executive for the fiscal year immediately preceding the fiscal year in which the Non-Compete Commencement Date occurs (the “Non-Compete Payment”); provided, however, that in the case of a termination of the Executive’s employment that occurs on or after the Expiration Date, the Company shall be required to provide the Executive written notice not less than twelve (12) months before the Expiration Date that it will require the Executive to comply with such non-competition covenant (and, if the Company does not timely provide such notice to the Executive prior to such a termination of the Executive’s employment by the Company, the Executive will not be subject to the non-competition covenant in Section 9.2).
