           Transaction Valuation*                          Amount of Filing Fee**
- ---------------------------------------------------------------------------------
               $118,339,092.50                                   $23,667.82



 *  Estimated for purposes of calculating the amount of the filing fee only.
    Calculated by adding (i) the product of $8.45, the per share Common Stock
    tender offer price, multiplied by 16,222,970, the sum of the 12,034,866
    currently outstanding shares of Common Stock sought in the Offer, the
    3,033,104 shares of Common Stock issuable pursuant to outstanding stock
    options and 1,155,000 shares of Common Stock issuable upon exercise of
    outstanding warrants and (ii) the product of $105.625, the per share
    Preferred Stock tender offer price, multiplied by 110,000, the total number
    of outstanding shares of Preferred Stock, and subtracting $30,363,754.00,
    (which equals 4,188,104 multiplied by $7.25, the average exercise price of
    the outstanding options and warrants).
**  Calculated as 1/50 of 1% of the transaction value.

   11(a)(2) and identify the filing with which the offsetting fee was
   previously paid. Identify the previous filing by registration statement
   number, or the Form or Schedule and the date of its filing.
