          directors who currently contemplate resigning all resign prior to May
          14, 2001, the authorized size of the board will be seven (7) members
          on May 14, 2001. Presently, the board is seeking an additional outside
          director to join the board. The Company from time to time evaluates
          strategic acquisitions and will continue to do so in the future. The
          Company may issue its stock or pay cash in connection with such
          acquisitions. The Company may obtain cash for such acquisitions
          through a variety of means, including without limitation, through the
          issuance of additional stock.
