                         SPECIAL MEETING OF STOCKHOLDERS
                                  JULY 26, 2007

                                 --------------

      This proxy statement is furnished to  stockholders  of SIGA  Technologies,
Inc.   ("SIGA")  in  connection  with  the  solicitation  of  proxies,   in  the
accompanying  form, by the Board of Directors of SIGA (the "Board of Directors")
for use in voting at the Special Meeting of Stockholders (the "Special Meeting")
to be held at the offices of Kramer Levin Naftalis & Frankel LLP, 1177 Avenue of
the Americas,  29th Floor, New York, New York 10036, on Thursday, July 26, 2007,
at 10:00 a.m., and at any adjournment or postponement thereof.

      This proxy statement,  and the accompanying form of proxy, are first being
mailed to stockholders on or about June 20, 2007.

                    VOTING RIGHTS AND SOLICITATION OF PROXIES

Purpose of the Special Meeting

      The  specific  proposal  to be  considered  and acted upon at the  Special
Meeting  is  summarized  in  the  accompanying  Notice  of  Special  Meeting  of
Stockholders. The proposal is described in more detail in this proxy statement.

Record Date and Outstanding Shares

      The Board of Directors has fixed the close of business on June 14, 2007 as
the record  date (the  "Record  Date")  for the  determination  of  stockholders
entitled to notice of, and to vote at, the Special Meeting. Only stockholders of
record at the close of  business  on the Record Date will be entitled to vote at
the Special Meeting or any and all adjournments or postponements  thereof. As of
the Record Date,  SIGA had issued and  outstanding  33,491,478  shares of common
stock, par value $.0001 per share.

Voting at the Special Meeting

      Each share of common stock outstanding on the Record Date will be entitled
to one vote on the matter submitted to a vote of the stockholders.

      The presence,  in person or by proxy,  of the holders of a majority of the
votes  entitled to be cast by the  stockholders  entitled to vote at the Special
Meeting is necessary to constitute a quorum.  Abstentions and broker "non-votes"
are  counted as present  and  entitled to vote for  purposes  of  determining  a
quorum.  A  broker  "non-vote"  occurs  when  a  nominee  holding  shares  for a
beneficial owner does not vote on a particular proposal because the nominee does
not  have  discretionary  voting  power  for  that  particular  item and has not
received instructions from the beneficial owner.

      For  the  amendment  of  the  certificate  of  incorporation  to  increase
authorized  common stock by 50,000,000  shares to  100,000,000  shares of common
stock, the affirmative vote of a majority of the total votes entitled to be cast
by the  stockholders  on such  proposal  in  person  or by proxy at the  Special
Meeting is required.  Abstentions  and broker  "non-votes" for such proposal are
not considered to have been voted on the proposal.


                                       1


Revocability and Voting of Proxies

      Any person signing a proxy in the form  accompanying  this proxy statement
has the  power to  revoke  it prior to the  Special  Meeting  or at the  Special
Meeting prior to the vote  pursuant to the proxy.  A proxy may be revoked by any
of the following methods:

o     by writing a letter  delivered to Thomas N.  Konatich,  Secretary of SIGA,
      stating that the proxy is revoked;

o     by submitting another proxy with a later date; or

o     by attending the Special Meeting and voting in person.

      Please note, however, that if a stockholder's shares are held of record by
a  broker,  bank or other  nominee  and that  stockholder  wishes to vote at the
Special Meeting, the stockholder must bring to the Special Meeting a letter from
the broker,  bank or other  nominee  confirming  that  stockholder's  beneficial
ownership of the shares.

      Unless we receive  specific  instructions  to the  contrary or unless such
proxy is revoked,  shares  represented  by each properly  executed proxy will be
voted:  (i) FOR the amendment of the  certificate of  incorporation  to increase
authorized  common stock by 50,000,000  shares to  100,000,000  shares of common
stock;  and (ii) with respect to any other matters that may properly come before
the Special  Meeting,  at the  discretion  of the proxy  holders.  SIGA does not
presently anticipate that any other business will be presented for action at the
Special Meeting.

Solicitation

      SIGA will pay the costs relating to this proxy  statement,  the proxy card
and the Special  Meeting.  SIGA may reimburse  brokerage firms and other persons
representing  beneficial  owners of  shares  for their  expenses  in  forwarding
solicitation  material to  beneficial  owners.  Directors,  officers and regular
employees may also solicit proxies by telephone,  facsimile or other means or in
person. They will not receive any additional payments for the solicitation.

                                 PROPOSAL NO. 1

    APPROVAL OF THE AMENDMENT TO THE CERTIFICATE OF INCORPORATION TO INCREASE
                            AUTHORIZED CAPITAL STOCK

      The  Certificate  of  Incorporation   currently   authorizes  us  to  have
50,000,000  shares of common  stock.  The Board of  Directors  has  approved the
resolution and proposes to amend Article  FOURTH of our Restated  Certificate of
Incorporation to increase the authorized  common stock to 100,000,000  shares of
common stock.  Although SIGA has no current plans to issue any additional shares
of common stock,  other than in connection with granting stock options to senior
management  and  directors,   we  continuously   evaluate  potential  financing,
acquisition  and other  corporate  opportunities,  some of which may require the
issuance of our common  stock.  This  proposal  would not affect the validity or
status of any currently  outstanding shares of common stock. If this proposal is
approved by our stockholders, we plan to file with the Secretary of State of the
State of Delaware a  Certificate  of Amendment to our  Restated  Certificate  of
Incorporation substantially in the form attached to the proxy statement as Annex
A. Of the 50,000,000  currently authorized shares of common stock, as of June 4,
2007,  we  had  33,489,812  shares  of  common  stock   outstanding,   7,420,912
outstanding  options  to  acquire  shares of our  common  stock,  and  8,653,115
warrants to acquire shares of our common stock.

      The Board of Directors  believes  that an increase in the number of shares
of authorized  common stock would benefit us and our  stockholders  by giving us
needed  flexibility in our corporate  planning in responding to  developments in
our business, including possible financing and acquisition transactions,  common
stock splits or dividends and for other general corporate purposes.  Having such
authorized  shares  available  for issuance in the future would  provide us with
greater  flexibility  and, if necessary,  allow common stock to be issued in the
future without expense or delay.

      Unless otherwise  required by applicable law or regulation,  the shares of
common stock to be authorized  will be issued without further  authorization  by
vote or consent of the stockholders and on such terms and for such consideration
as may be determined by the Board of Directors.

      THE BOARD OF DIRECTORS  RECOMMENDS  THAT THE  STOCKHOLDERS  VOTE "FOR" THE
APPROVAL  OF THE  AMENDMENT  TO THE  CERTIFICATE  OF  INCORPORATION  TO INCREASE
AUTHORIZED CAPITAL STOCK.


                                       3


         SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

      The  following  tables  set  forth  certain   information   regarding  the
beneficial  ownership of SIGA's voting securities as of June 4, 2007 of (i) each
person known to SIGA to beneficially own more than 5% of the applicable class of
voting  securities,  (ii) each director and director nominee of SIGA, (iii) each
Named Executive Officer and (iv) all directors and executive officers of SIGA as
a group.  As of June 4, 2007, a total of 33,489,812  shares of common stock were
outstanding.  Each share of common  stock is  entitled to one vote on matters on
which  holders  of common  stock  are  eligible  to vote.  The  column  entitled
"Percentage  of Total Voting Stock  Outstanding"  shows the  percentage of total
voting stock beneficially owned by each listed party.

      The  number  of  shares  beneficially  owned  is  determined  under  rules
promulgated by the Securities and Exchange  Commission,  and the  information is
not necessarily  indicative of beneficial ownership for any other purpose. Under
those rules, beneficial ownership includes any shares as to which the individual
has sole or shared  voting power or  investment  power and also any shares which
the individual has the right to acquire within 60 days of June 4, 2007,  through
the exercise or conversion of any stock option, convertible security, warrant or
other  right.  Unless  otherwise  indicated,  each person or entity named in the
table has sole voting power and investment power (or shares that power with that
person's  spouse) with respect to all shares of capital stock listed as owned by
that person or entity.

                            Ownership of Common Stock

      The  following  tables  set  forth  certain   information   regarding  the
beneficial  ownership of SIGA's  voting  securities  as of June 4, 2007 of (i)
each person  known to SIGA to  beneficially  own more than 5% of the  applicable
class of voting  securities,  (ii) each  director and director  nominee of SIGA,
(iii) each Named Executive Officer,  and (iv) all directors and officers of SIGA
as a group.  As of June 4, 2007, a total of 33,489,812  shares of common stock
were outstanding.  Each share of common stock is entitled to one vote on matters
on  which  common  stockholders  are  eligible  to  vote.  The  column  entitled
"Percentage  of Total Voting  Stock" shows the  percentage of total voting stock
beneficially owned by each listed party.
