7.3. For purposes hereof, “Good Reason” means (i) a substantial reduction by the Corporation of the Executive’s Base Salary or Annual Bonus Incentive (as that term is defined in paragraph 4.2) in effect immediately prior to such reduction; (ii) the assignment to the Executive of duties or responsibilities inconsistent with the position and office held by the Executive immediately prior to such assignment; or (iii) the substantial reduction in or loss of authority and responsibility which the Executive was empowered with immediately prior to such reduction or loss.

fifty-one percent (51%) or more of the voting power for the election of directors of the Corporation;

(ii) there shall be consummated any consolidation, merger or stock-for-stock exchange involving securities of the Corporation in which the holders of voting securities of the Corporation immediately prior to such consummation own, as a group, immediately after such consummation, voting securities of the Corporation (or if the Corporation does not survive such transaction, voting securities of the corporation surviving such transaction) having less than fifty percent (50%) of the total voting power in an election of directors of the Corporation (or such other surviving corporation);
