such bonus shall be determined by the Compensation Committee and approved by the full
Board of Directors of the Company; (3) pay Murdakes severance pay in an amount equal to
Murdakes monthly retainer on the termination date multiplied by six months if the
Company terminates him without cause (as defined below) or to pay Murdakes severance pay

          A merger or consolidation of the Company whether or not approved by the Board of
          Directors of the Company, other than a merger or consolidation which would

          thereto continuing to represent (either by remaining outstanding or by being
          converted into voting securities of the surviving entity) at least fifty percent
          (50%) of the total voting power represented by the voting securities of the
          Company or such surviving entity outstanding immediately after such merger or
