        <footnote id="F1">On May 22, 2013, the Issuer completed a recapitalization pursuant to which it, among other things, issued a stock dividend of three shares of class A common stock for each share of then-existing common stock and reclassified each share of its then-existing common stock as one-half of one share of class B common stock. All fractional shares of class B common stock were cashed-out in the recapitalization.  In connection with the recapitalization, the exercise prices of outstanding options were equitably adjusted to prevent the dilution or enlargement of the benefits intended to be provided.</footnote>
