                  SIGA TECHNOLOGIES COMPLETES PRIVATE PLACEMENT

NEW YORK, January 9, 2003 -- SIGA Technologies, Inc. (NASDAQ: SIGA and
FRANKFURT: SGW 919 473), a biopharmaceuticals company focusing on antibiotics
and vaccines directed at bacterial infections, anticipates the completion of a
closing of a private placement of up to 34 units consisting of 1.7 million
shares of its common stock to a group of private investors. The gross proceeds
from the offering will be approximately $1.85 million, with net proceeds of
approximately $1.65 million to SIGA.

SIGA is identifying and developing novel anti-infective agents based on its
pioneering research in the field of bacterial surface proteins, structures used
by bacteria to initiate and maintain an infection. Drug candidates that
interfere with surface protein expression are expected to be effective against a
wide range of disease-causing bacteria, including antibiotic resistant bacteria,
by blocking the attachment of bacteria to human tissue, the first step in the
infection process. By comparison, antibiotics available today act by interfering
with either the structure or the metabolism of a bacterial cell, affecting its
ability to survive and to reproduce. No currently available antibiotics target
the attachment of a bacterium to its target tissue. Once prevented from
attaching to and colonizing human tissue, bacteria are readily cleared by the
body's immune system.

SIGA's lead product development programs focus on biological warfare defense,
mucosal vaccines for strep throat and sexually transmitted diseases, commensal
bacteria for the delivery of vaccines and protein therapeutics and novel
antibiotics for gram positive and gram negative bacteria.

This news release contains certain "forward-looking statements" within the

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.

forth in SIGA's filings with the Securities and Exchange Commission, including
SIGA's Annual Report on Form 10-K for the fiscal year ended December 31, 2001,

Commission. Investors and security holders are urged to read those documents
