        <footnote id="F2">The number of awards shown is at the highest level, with the target level being an aggregate of 16,000,000 shares; the actual number of shares of Class A Common Stock issuable upon vesting is subject to adjustment based on the greatest result of three tests tied to the stock price of the Issuer's Class A Common Stock relative to performance of the companies comprising the Nasdaq-100 Index as of  the Grant Date, and may range from 80% to 120% of the target level (12,800,000 to 19,200,000 shares in the aggregate).</footnote>
