================================================================================
      TRANSACTION VALUATION                     AMOUNT OF FILING FEE

        $50,146,119.00 (1)                       $10,029.22 (2)(3)
================================================================================


      (1)   Estimated for purposes of calculating the amount of filing fee only.
            The amount assumes (i) the purchase of 4,500,204 shares of common

            at a price per share of $11.00 in cash, (ii) the purchase of 84,000
            options at an average price of $4.62 per share and (iii) the
            purchase of one warrant for 50,000 shares at a purchase price of
            $5.125 per share. The purchase price for each of the options and the
            warrant represents the difference between the exercise price of such

            warrants described in items (i), (ii) and (iii) of the preceding

      (2)   Calculated as 1/50th of 1% of the transaction value.

      (3)   Wired to the SEC's lockbox account on July 24, 2001.
