Item 3 of the Schedule 13D is hereby amended and restated in its entirety as follows:
 
On March 7, 2002, pursuant to a Securities Purchase Agreement, dated as of March 7, 2002, between the Issuer and Defiante, Defiante purchased 4,255,319 shares of Common Stock at a cash purchase price of $0.235 per share as part of a private placement. Defiante used its working capital to purchase such shares.
 
On June 11, 2003, pursuant to a Securities Purchase Agreement, dated as of June 11, 2003, between the Issuer and Defiante, Defiante purchased 3,184,713 shares of Common Stock at $0.628 per share. Defiante used its working capital to purchase such shares. In consideration for the purchase of such shares, on June 11, 2003, the Issuer issued to Defiante a warrant (“Warrant A”) to purchase 750,000 shares of Common Stock exercisable at a price of $1.00, in whole or in part, at any time and from time-to-time from issuance of such warrant through December 11, 2004 and (ii) a warrant (“Warrant B” and, collectively with Warrant A, the “2003 Warrants”) to purchase up to a number of shares of Common Stock determined by dividing $750,000 by the Warrant B Exercise Price (as defined below) during the Warrant B Period (as defined below).  The Warrant B Period was defined as the period commencing on the earlier of (a) the date the Issuer closed the next round of private financing (after June 11, 2003) totaling at least $2,000,000 (the “Next Private Placement”) or (b) December 11, 2003, and ending on December 11, 2004.  The initial Warrant B Exercise Price was equal to the greater of (a) $1.25 or (b) the price per common share (either directly or after giving effect to any conversion into common shares) at which the Company closed the Next Private Placement.  As a result of the 2004 Common Stock Transaction (as defined below), the Warrant B Exercise Price became fixed at $1.25 on January 23, 2004.  The Warrant B was then exercisable for 600,000 shares of Common Stock.
 
The terms of Warrant A and Warrant B were amended on September 2, 2004 pursuant to a Warrant Amendment Agreement dated as of September 2, 2004 to provide that, if the holder exercised the 2003 Warrants, by not later than September 6, 2004, the 2003 Warrants would be exercisable for a total of 1,382,488 shares of Common Stock at an exercise price of $1.085 per share.
 
Defiante exercised the 2003 Warrants on September 3, 2004 at an exercise price of $1.085 per share and received 1,382,488 shares of Common Stock.  Defiante used its working capital to pay the exercise price.
 
On January 23, 2004, pursuant to a Securities Purchase Agreement, dated as of January 23, 2004, between Issuer and Defiante, Defiante purchased 1,052,632 shares of Common Stock at $0.95 per share (the “2004 Common Stock Transaction”).  Defiante used its working capital to purchase such shares.  In consideration for the purchase of such shares, on January 23, 2004, the Issuer issued to Defiante a warrant (the “2004 Warrant”) to purchase 263,158 shares of Common Stock exercisable at a price of $1.50, in whole or in part, at any time and from time-to-time from issuance of such warrant through July 23, 2006.
