          Transaction Valuation*                   Amount of Filing Fee**
---------------------------------------- ---------------------------------------

---------------------------------------- ---------------------------------------
             $152,034,519.66                             $12,299.59
======================================== =======================================
*    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.
|X|  Check the box if any part of the fee is offset as provided by Rule
     0-11(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.

be exercised or waived before the Offer expires." The amended sentence shall
read as follows:

         "The failure by Parent or Purchaser at any time to exercise any of the
foregoing rights shall not be deemed a waiver of any such right; the waiver of
any such right with respect to particular facts and other circumstances shall
not be deemed a waiver with respect to any other facts and circumstances; and
each such right shall be deemed an ongoing right that may be asserted at any
time and from time to time; provided, however, that, other than with respect to

restated in its entirety to read as follows:

         "The projections provided to Parent by the Company were consistent with
publicly available data regarding the Company's expected future performance and
were not material to Parent's decision to enter into the Merger Agreement and

Shares pursuant to the Offer."
