*     Estimated for purposes of calculating the amount of the filing fee only.
      The fee was calculated by multiplying $22.00, the per share tender offer
      price, by the 5,970,156 currently outstanding shares of Common Stock
      sought in the Offer, which gives an aggregate consideration of
      $131,343,432.00 (the "Common Stock Consideration"). The Common Stock
      Consideration was then added to $20,691,087.66, being the net
      consideration for the Subject Company's 1,448,662 stock options, to arrive
      at a total transaction value of $152,034,519.66.

**    Calculated as 0.008090% of the transaction value.
