Item 5. Other Events

On December 31, 2002, SIGA Technologies, Inc. (the "Company") received gross
proceeds of $990,000 from a private placement of 900,000 shares of its common
stock, and net proceeds of $891,000. On the completion of certain ministerial
actions, the Company anticipates it will receive additional gross proceeds of
$690,000 from this offering for an additional 627,300 shares of its common
stock. The net proceeds to the Company will be $621,000.

Further, the Company anticipates receiving gross proceeds of up to an additional
$170,000 upon completion of the placement of the remaining 172,700 shares
offered in the private placement, proceeds to the Company will be $153,000,
however no assurance can be given that the closing with respect to these
securities will occur.

Statements contained herein and in future fillings by the Company with the
Securities and Exchange Commission, in the Company's press releases, and in oral
statements made by, or with the approval of, authorized personnel that relate to
the Company's future performance, including, without limitation, statements with
respect to the Company's anticipated results of operations or level of business
for 2002 or for any other future period, are "forward-looking statements" within
the meaning of the Private Securities Litigation Reform Act of 1995. Such
statements, including statements regarding the efficacy and intended utilization
of SIGA's technologies under development, are not guarantees of future
performance. Actual results may differ materially from the expectations
contained in the forward-looking statements. Factors which may cause such
differences include the risk that potential products that appeared promising in
early research or clinical trials to SIGA or its collaborators do not
demonstrate efficacy or safety in subsequent pre-clinical or clinical trials,
and the risk that SIGA or its collaborators will not obtain appropriate or
necessary governmental approvals to market products tested in such trials.

More detailed information about SIGA and the factors discussed above is set
forth in SIGA's fillings with the Securities and Exchange Commission, including
SIGA's Annual Report on Form 10-K for the fiscal year ended December 31, 2001,
and in other documents that SIGA has filed with the U.S. Securities and Exchange
