        <footnote id="F1">The shares of Class A Common Stock are subject to a Performance-Based Restricted Stock Award (&quot;PRSA&quot;) granted to the Reporting Person and are reported at the target award amount. The Reporting Person may potentially earn from 0% to 150% of the target amount based on the achievement, if any, of the performance criteria through the end of the performance period. The actual shares earned will be determined upon certification by the Issuer's Compensation Committee. If earned, 1/3rd of the total earned shares would vest on December 20, 2018 (and be released on March 20, 2019), and 1/12th of the total earned shares would vest on each of March 20, June 20, September 20 and December 20, over the following two years, subject to the Reporting Person's Continuous Service (as defined in the Issuer's 2015 Equity Incentive Plan) through such dates.</footnote>
