        <footnote id="F1">Pursuant to a reclassification exempt under Rule 16b-7, each share of  Class A and B Common Stock and Preferred Stock are converting, immediately and automatically, into shares of Common Stock, as part of a recapitalization of the issuer's capital stock structure.</footnote>
        <footnote id="F2">As of the transaction date, 50% of these shares have vested.  On June 30, 2010 an additional 25% will vest and the final 25% will vest on June 30, 2011.</footnote>
