        <footnote id="F1">On August 27, 2009, in connection with a litigation settlement, the Issuer issued to the Reporting Person a convertible note
 (the &quot;Convertible Note&quot;) in an aggregate amount of $5,000,000 in consideration of a $5,000,000 loan made by the Reporting
 Person to the Issuer.  The Convertible Note is convertible into units (the &quot;Units&quot;) upon the occurrence of certain events.
 Each Unit consists of (i) one share of the Issuer's Series D Non-Convertible Preferred Stock, and (ii) a Warrant to purchase
 one share of the Issuer's Common Stock.  Accordingly, at the time the Convertible Note is converted into the Units, the
 Reporting Person will receive (i) 4,970,179 shares of Series D Non-Convertible Preferred Stock, and (ii) Warrants to
 purchase 4,970,179 shares of Common Stock.   The Warrants are immediately exercisable after issuance at an exercise price of
 $12.00 and expire on the twelfth anniversary of the issuance date.</footnote>
        <footnote id="F2">The Convertible Note is not convertible at the option of the Reporting Person until the Certificate of Designation for the
 Series D Non-Convertible Preferred Stock is filed by the Issuer and becomes effective, as contemplated by the Convertible
 Note. The Convertible Note is not automatically convertible until the rights offering, as contemplated by the Convertible
 Note, is consummated or until the first business day following the date on which the Issuer provides the Reporting Person
 with written notice that Pegasus Partners IV, L.P. has converted its convertible note into Units.</footnote>
        <footnote id="F3">The maturity date is the earliest of July 31, 2010 or the consummation of the rights offering, as contemplated by the
 Convertible Note or the first business day following the date on which the Issuer provides the Reporting Person with written
 notice that Pegasus Partners IV, L.P. has converted its convertible note into Units.</footnote>
