                     TRANSACTION VALUATION*                                              AMOUNT OF FILING FEE**
----------------------------------------------------------------------------------------------------------------------------------
                                                                                      
                           $258,900.80                                                           $20.97
==================================================================================================================================

*        Calculated solely for the purpose of determining the amount of the
         filing fee, based upon the purchase of 1,153,808 options at the
         purchase price applicable to each option. The purchase price for each
         option is the greater of (a) the amount by which $10.00 exceeds the
         exercise price of the option, if any, and (b) $.10. This offer relates
         to options at the following exercise prices: (i) 69,000 options at
         $7.82; and (ii) 1,084,808 options at exercise prices greater than
         $10.00. This amount includes 740,587 options held by executive
         officers and directors of the subject company. Such executive officers
         and directors have agreed to have their options cancelled without cash
         payment. The amount of the filing fee, calculated in accordance with
         Rule 0-11 of the Securities Exchange Act of 1934, as amended, equals
         $80.90 per $1,000,000 of the value of the transaction valuation.
