1. Subject to certain conditions, at the effective time, all unexercised options with an exercise price below $6.30 were cancelled and converted into the right to receive (i) a cash payment of (A) $6.30 less the exercise price, multiplied by (B) the number of shares subject thereto and (ii) one CVR per share subject thereto. Options with an exercise price of $6.30 or greater were cancelled and converted into the right to receive a cash payment with respect to each share subject thereto upon each milestone payment date equal to (i) the amount by which, as of the payment date, the sum of (x) $6.30, (y) the amount per share previously paid in respect of any earlier payment date and (z) the amount in cash to be paid at such payment date exceeds the exercise price payable under such option, less (ii) the amount of all payments previously received with respect to such option. Options with an exercise price of $8.30 or greater were cancelled without any consideration payable therefor.
