Item 3.01. Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On January 31, 2006, SIGA Technologies, Inc. (“SIGA”) received notice from the Nasdaq Stock Market (“NASDAQ”) that for the past 30 consecutive business days, the bid price of the SIGA’s common stock has closed below the $1.00 per share minimum requirement for continued inclusion on the Nasdaq SmallCap Market under Marketplace Rule 4310(c)(4). In accordance with Marketplace Rule 4310(c)(8)(D), SIGA will be provided with 180 calendar days, until July 31, 2006, to regain compliance with the minimum bid requirement. If, at any time before July 31, 2006, the bid price of the SIGA’s common stock closes at $1.00 per share or more for a minimum of 10 consecutive business days, NASDAQ will provide SIGA with written notification that it now complies with Marketplace Rule 4310(c)(4). SIGA intends to monitor the bid price between now and July 31, 2006, and consider available options if its common stock does not trade at a level likely to result in SIGA regaining compliance with the minimum bid requirement.

On February 3, 2006, SIGA issued a press release announcing that it had received the above described notice from NASDAQ regarding its bid price. A copy of the press release is attached hereto as Exhibit 99.1.
