In the event that Executive’s employment with the Company is terminated (other than as a consequence of death or Disability) either (x) by the Company for any reason other than for Cause during a Pending Change of Control or within one year following the occurrence of a Change of Control, or (y) by Executive for Good Reason within one year following the occurrence of a Change of Control, then Executive shall be entitled to receive from the Company the following:

ii)	a cash lump sum equal to the amount of accrued but unpaid Incentive Compensation earned by the Executive, which amount shall be prorated for the year in which the termination occurs and shall be calculated through the end of the last full month prior to the Termination Date with a proportionate

adjustment to all caps and floors, if any, based upon the portion of the fiscal year worked prior to the termination of Executive’s employment; and


iii)	full vesting of all outstanding stock options and restricted stock grants held by Executive.

The Company shall make termination payments required by Section 2(a)(i) within ten (10) days of the Termination Date, and payments required by Section 2(a)(ii) within thirty (30) days of the Termination Date; provided, however, if such ten (10) day or thirty (30) day period begins in one calendar year and ends in another, Executive will not have the right to specify the calendar year of payment. All payments to be made to the Executive upon a termination of employment may only be made upon a “separation from service” (within the meaning of Section 409A) of the Executive. For purposes of Section 409A, (i) each payment made under this Agreement shall be treated as a separate payment; (ii) the Executive may not, directly or indirectly, designate the calendar year of payment; and (iii) no acceleration of the time and form of payment of any nonqualified deferred compensation to the Executive or any portion thereof, shall be permitted.

ii.

Individuals who, as of the Effective Date, constitute the Board (the “Incumbent Board”) cease for any reason to constitute at least a majority of the Board, provided that any individual becoming a director subsequent to the date hereof whose election or nomination for election by the Company’s shareholders, was approved by a vote of at least a majority of the directors then comprising the Incumbent Board shall be considered as though such individual were a member of the Incumbent Board, but excluding, for this purpose, any such individual whose initial assumption of office is in connection with an actual or threatened election contest relating to the election of the Directors of the Company (as such terms are used in Rule 14a-11 of Regulation 14A, or any successor section, promulgated under the Exchange Act); or

iii.

Approval by the shareholders of the Company of a reorganization, merger or consolidation (a “Business Combination”), in each case, with respect to which all or substantially all holders of the Outstanding Capital Stock and Voting Securities immediately prior to such Business Combination do not, following such Business Combination, beneficially own, directly or indirectly, more than 60% of, respectively, the then outstanding shares of common stock and the combined voting power of the then outstanding voting securities entitled to vote generally in the election of directors, as the case may be, of the corporation resulting from the Business Combination; or

iv.

a complete liquidation or dissolution of the Company or (b) a sale or other disposition of all or substantially all of the assets of the Company other than to a corporation with respect to which, following such sale or disposition, more than 60% of respectively, the then outstanding shares of common stock and the combined voting power of the then outstanding voting securities entitled to vote generally in the election of directors is then owned beneficially, directly or indirectly, by all or substantially all of the individuals and entities who were the beneficial owners, respectively, of the Outstanding Capital Stock and Voting Securities immediately prior to such sale or disposition in substantially the same proportion as their ownership of the Outstanding Capital Stock and Voting Securities, as the case may be, immediately prior to such sale or disposition; or

or exchange for another benefit; and (iv) each reimbursement payment or provision of in-kind benefit shall be one of a series of separate payments (and each shall be construed as a separate identified payment) for purposes of Section 409A.

Thereafter, the Term shall continue for successive one (1) year terms (the “Additional Terms”) unless either the Company or the Executive provides written notice of termination of this Agreement not less than one hundred twenty (120) days prior to the end of the Initial Term or any Additional Term, or unless earlier terminated by the mutual written consent of the Company and the Executive.
