   options with an exercise price of less than $7.32 per share, multiplied by
   $7.32 less $6.89, the average exercise price of such options, and (iii)
   265,000 shares of common stock subject to warrants multiplied by $7.32 less
   $7.00, the exercise price of such warrants.

** Calculated as 1/50 of 1% of the transaction value.
