Explanation of Responses:
( 1)  On February 24, 2014, the reporting person was granted a stock option to purchase 50,000 shares of common stock. The option vested as to 12,500 of the shares subject to the option upon the compensation committee's certification that certain performance criteria had been met ("Performance Critieria 1"), which certification occurred on November 10, 2015, resulting in the vesting of the option as to 12,500 shares on that date. As a result of Performance Criteria 1 being satisfied, in addition to the vesting of the option as to 12,500 shares on November 10, 2015, an additional 12,500 of the shares subject to the option will now vest on November 10, 2016, subject to continuous service. Note this is in addition to the 25,000 options previously disclosed for meeting certain performance criteria ("Performance Criteria 2") which was certified on January 7, 2015.
