        <footnote id="F1">The Conversion Price of the Series B Mandatorily Convertible Redeemable Preferred Stock (&quot;Preferred Stock&quot;) may be calculated
 by dividing the Liquidation Preference of the Preferred Stock by its Conversion Ratio.  Pursuant to the Certificate of
 Designations of the Preferred Stock filed with the Issuer's 8K on April 5, 2005, the Liquidation Preference is $40 per
 share, and the Conversion Ratio is (X - (60,000,000 plus Y)) / 1,000,000.  Y equals the number of fully diluted shares of
 common stock on March 31, 2005.  X equals: Y divided by .05.</footnote>
        <footnote id="F2">Elliott Associates, L.P. (&quot;Elliott Associates&quot;), directly owns 54,238,206 shares of Common Stock after converting 88,316

 Issuer's Certificate of Incorporation, which was December 12, 2005.</footnote>
        <footnote id="F4">The Preferred Stock was issued to Elliott Associates, Manchester and others in exchange for an aggregate of approximately $85
