CALCULATION OF FILING FEE

---

*

Estimated for purposes of calculating the amount of the filing fee only. The transaction value was calculated by multiplying $10.60, the per share tender offer price, by the 15,471,007 shares of Common Stock outstanding as of May 20, 2004 sought in the Offer, which gives an aggregate consideration of $163,992,674.20 (the "Common Stock Consideration"). The Common Stock Consideration was then added to (1) $5,731,950, being the consideration for the Subject Company's 540,750 stock options and (2) $4,709,896.60, being the net consideration for the Subject Company's 741,716 warrants, to arrive at a total transaction value of $174,434,520.80.

**
