CALCULATION OF FILING FEE

Transaction Valuation*		Amount of Filing Fee**
$294,000,586.00		$20,962.24

* Calculated solely for purposes of determining the filing fee. The calculation assumes the purchase of 30,534,195 shares of common stock, par value $0.001 per share, at $8.20 per share. The transaction value also includes the aggregate offer price for 3,688,167 shares issuable pursuant to outstanding options with an exercise price less than $8.20 per share, which is calculated by multiplying the number of shares underlying such outstanding options at each exercise price therefor by an amount equal to $8.20 minus such exercise price. The transaction value also includes the aggregate net offer price for 125,000 shares issuable pursuant to a warrant and 1,700,000 shares issuable pursuant to a confidentiality and non-competition agreement with Mr. Kerry R. Hicks, the Chief Executive Officer of Health Grades.
