                            CALCULATION OF FILING FEE

TRANSACTION VALUATION*                                    AMOUNT OF FILING FEE**
     $94,660,000                                                 $8,709


*Estimated for purposes of calculating the amount of the filing fee only. The
fee was calculated by (i) multiplying $6.8426, the per share tender offer
price for shares of Common Stock, by 9,857,691, the currently outstanding
shares of Common Stock sought in the Offer, which gives an aggregate
consideration of $67,452,236.44 (the "Common Stock Consideration"), and (ii)
multiplying $13.6852, the per share tender offer price for shares of
Preferred Stock, by 1,114,485, the currently outstanding shares of Series A
Convertible Preferred Stock sought in the Offer, which gives an aggregate
consideration of $15,251,950.12 for such Preferred Stock (the "Preferred
Stock Consideration" and together with the Common Stock Consideration, the
"Total Stock Consideration"). The Total Stock Consideration was then added to
$11,955,251.98, being the net consideration for the Subject Company's
2,714,347 in-the-money employee stock options and warrants to arrive at a
total transaction value of approximately $94,660,000.

**Calculated at the rate of $92.00 per $1 million.
