Calculation of Filing Fee

Transaction valuation*	Amount of filing fee*
$96,812,233	$11,249.59

* This calculation is based upon $0.0001162 multiplied by the transaction valuation shown above. For purposes of calculating this fee only, the transaction valuation is based on the aggregate number of securities to which the transaction applies multiplied by the merger consideration of $2.82 per share. For purposes of calculating the aggregate number of securities only, this number is based on (i) 32,141,724 shares of ChyronHego Corporation common stock outstanding and owned by shareholders other than 8,258,706 shares (the “Rollover Shares”) owned by the Rollover Holders (as defined below); (ii) outstanding stock options to purchase an aggregate of 5,487,907 shares of ChyronHego Corporation common stock with exercise prices below the merger consideration of $2.82 per share which are eligible to be cashed out in the merger and (iii) 1,097,159 shares of common stock subject to warrants with exercise prices below the merger consideration of $2.82 per share. For purposes of calculating the per unit price, this price is based on the fact that (i) each outstanding share of common stock owned by shareholders (other than the Rollover Holders with respect to the Rollover Shares) will be converted into the right to receive $2.82 in cash, without interest, (ii) each outstanding stock option to purchase shares of ChyronHego Corporation common stock with a per share exercise price less than $2.82 will be converted into the right to receive a cash payment equal to (a) the excess of $2.82 over the per share exercise price for the shares of common stock subject to such stock option, multiplied by (b) the number of shares of common stock underlying such stock option and (iii) each warrant to purchase common stock that has an exercise price less than $2.82 will be converted into the right to receive a cash payment equal to the excess of $2.82 over the per share exercise price of such warrant.

☒ Check the box if any part of the fee is offset as provided by Section 240.0-11(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.
