     of securities of the Company representing fifty percent (50%) or more of
     the total voting power represented by the Company's then outstanding voting
     securities;

          (2) The consummation of a merger or consolidation of the Company with

     by being converted into voting securities of the surviving entity or such
     surviving entity's parent) at least fifty percent (50%) of the total voting
     power represented by the voting securities of the Company or such surviving
     entity or such surviving entity's parent outstanding immediately after such
