        <footnote id="F3">The Amended and Restated 7% Senior Secured Convertible Notes (each a &quot;Convertible Note&quot;) were originally issued as Secured
 Grid Notes on October 23, 2002, October 24, 2003, July 23, 2004, and November 10, 2004, respectively.  Each Secured Grid
 Note was amended and restated on June 26, 2007 as an amended and restated 7% Senior Secured Convertible Note
 convertible into shares of common stock at a conversion price of $0.20 per share.  Each of the Convertible Notes converts
 into shares of common stock at a rate determined by dividing the then outstanding principal amount by the then conversion
 price.  Accrued interest is added to the outstanding principal amount.  The number of shares into which each of the
 Convertible Notes converts shall be adjusted according to typical anti-dilution provisions.  More information about the
 Convertible Notes can be found in the Form 8-K filed by the issuer with the Securities and Exchange Commission on June 26,
 2007.</footnote>
        <footnote id="F4">Manchester shall not be entitled to exercise its rights to convert the Convertible Notes into common stock until the issuer
 first obtains the approval of its stockholders to (i) increase the number of authorized shares of common stock available for
 issuance under its Certificate of Incorporation, as amended and (ii) issue the shares of common stock pursuant to American
 Stock Exchange (&quot;AMEX&quot;) rules as well as to obtain the approval of AMEX to list the common stock reported in Table I of this
 Form 4 and the shares issuable upon conversion of the Convertible Notes on AMEX. The issuer is required to obtain these
 approvals within one year of the issuance date of the Convertible Notes. In the event that these required approvals are not
 obtained by that time, then the interest rate on the amended and restated Notes will increase to a rate of 15% per annum.</footnote>
