        <footnote id="F1">Every one share of Series F Redeemable Convertible Preferred Stock (&quot;Preferred Stock&quot;) is initially convertible into ten shares of Common Stock of the issuer. The conversion ratio of the Preferred Stock is equal to the product of (i) the number of shares of Preferred Stock being so converted multiplied by (ii) the quotient of (x) the Series F Accreted Value divided by (y) $1.40, subject to anti-dilution adjustments. Series F Accreted Value means, with respect to each share of Preferred Stock, the  sum of $14.00 plus all dividends that have accrued and compounded semi-annually with respect thereto.</footnote>
