        <footnote id="F1">On February 11, 2016, pursuant to Cavium's 2007 Equity Incentive Plan, Cavium's Compensation Committee granted a one-year performance based RSU to the reporting person based on achievement of a certain milestone. The performance based RSU earned upon achievement of the certain milestone will vest and the underlying common stock of Cavium will be issued to the reporting person on January 31, 2017. As determined by Cavium's Compensation Committee on January 27, 2017, the performance criteria was met at a level that caused 13,158 shares to vest, and the reporting person received the same number of shares of Cavium's common stock at no cost.</footnote>
