Konatich Secretary New York, New York November 22, 2004 SIGA Technologies, Inc. 420 Lexington Avenue, Suite 601 New York, New York 10170 -------------- PROXY STATEMENT ANNUAL MEETING OF STOCKHOLDERS DECEMBER 14, 2004 -------------- 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 Annual Meeting of Stockholders (the "Annual Meeting") to be held at the offices of Kramer Levin Naftalis & Frankel LLP, 919 Third Avenue, 37th Floor, New York, New York 10022, on Tuesday, December 14, 2004, at 10:30 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 November 22, 2004. VOTING RIGHTS AND SOLICITATION OF PROXIES Purpose of the Annual Meeting The specific proposals to be considered and acted upon at the Annual Meeting are summarized in the accompanying Notice of Annual Meeting of Stockholders. Each 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 October 22, 2004 as the record date (the "Record Date") for the determination of stockholders entitled to notice of, and to vote at, the Annual Meeting. Only stockholders of record at the close of business on the Record Date will be entitled to vote at the Annual Meeting or any and all adjournments or postponements thereof. As of the Record Date, SIGA had issued and outstanding 24,500,648 shares of common stock, par value $.0001 per share ("Common Stock"), and 64,864 shares of series A convertible preferred stock, par value $.0001 per share ("Series A Preferred Stock"). The Common Stock and the Series A Preferred Stock together comprise all of SIGA's issued and outstanding voting stock. Voting at the Annual Meeting Each share of Common Stock and each share of Series A Preferred Stock outstanding on the Record Date will be entitled to one vote on each matter submitted to a vote of the stockholders. Cumulative voting by stockholders is not permitted. 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 Annual 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 election of directors, a plurality of the votes cast is required. Abstentions and broker "non-votes" are not considered for the purpose of the election of directors. For the ratification of the appointment of PricewaterhouseCoopers LLP as the independent registered public accounting firm of SIGA for the fiscal year ending December 31, 2004, the affirmative vote of a majority of the total votes cast on such proposal in person or by proxy at the Annual Meeting is required. Abstentions and broker "non-votes" for such proposal are not considered to have been voted on the proposal. 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 Annual Meeting or at the Annual 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 Annual 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 Annual Meeting, the stockholder must bring to the Annual 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 election of each of SIGA's nominees as a director; (ii) FOR the ratification of the appointment of PricewaterhouseCoopers LLP as the independent registered public accounting firm of SIGA for the fiscal year ending December 31, 2004; and (iii) with respect to any other matters that may properly come before the Annual Meeting, at the discretion of the proxy holders. SIGA does not presently anticipate that any other business will be presented for action at the Annual Meeting. Solicitation SIGA will pay the costs relating to this proxy statement, the proxy card and the Annual 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. -2- PROPOSAL NO. 1 ELECTION OF DIRECTORS Ten directors are to be elected at the Annual Meeting to hold office until the next Annual Meeting of Stockholders and until their successors have been duly elected and qualified. Unless otherwise instructed, the proxy holders will vote the proxies received by them FOR the election of the ten persons named in the table below as directors of SIGA. Proxies cannot be voted for a greater number of persons than the nominees named. In the event that any of the below listed nominees for director should become unavailable for election for any presently unforeseen reason, the persons named in the accompanying proxy form have the right to use their discretion to vote for a substitute.

During 2003, no director attended fewer than 75% of the aggregate of the meetings of the Board of Directors and committees thereof, if any, upon which such director served during the period for which he has been a director or committee member. In addition, actions were also taken during 2003 by unanimous written consent of the directors. Those members of the Board of Directors who are independent as defined by Rule 4200 of the NASD Marketplace Rules (the "Independent Directors") are also required, pursuant to Rule 4350(c)(2) of the NASD Marketplace Rules, to regularly convene executive sessions where only such Independent Directors are present. Such meetings may be in conjunction with regularly-scheduled meetings of the Board of Directors. Each member of the Board of Directors is also expected to attend the annual meeting of stockholders of SIGA. Two members of the Board of Directors attended SIGA's 2003 annual meeting of stockholders. Committees of the Board of Directors The Board of Directors currently has, and appoints the members of, standing Audit, Compensation and Nominating and Corporate Governance Committees. Each member of the Audit, Compensation and Nominating and Corporate Governance Committees is an Independent Director. Each of these committees has a written charter approved by the Board of the Directors in March 2004. A copy of each charter is posted on SIGA's website at www.siga.com under the "Corporate Governance" section. -5- Audit Committee. The Audit Committee, which currently consists of directors Paul G. Savas, Mehmet C. Oz and Michael A. Weiner, held four meetings during 2003. Each member of the Audit Committee is an Independent Director. The purpose of the Audit Committee is to assist the Board of Directors in the oversight of the integrity of the financial statements of SIGA, SIGA's compliance with legal and regulatory matters, the independent registered public accounting firm's qualifications and independence, and the performance of SIGA's independent registered public accounting firm. The primary responsibilities of the Audit Committee are set forth in its charter, and include various matters with respect to the oversight of SIGA's accounting and financial reporting process and audits of the financial statements of SIGA on behalf of the Board of Directors. The Audit Committee also selects the independent registered public accounting firm to conduct the annual audit of the financial statements of SIGA; reviews the proposed scope of such audit; reviews accounting and financial controls of SIGA with the independent registered public accounting firm and our financial accounting staff; and reviews and approves transactions between us and our directors, officers, and their affiliates. In addition to being available on SIGA's website (as described above), a copy of the Audit Committee charter is included in this proxy statement as Annex A. Also see "Audit Committee Report." It is anticipated that after the Annual Meeting Paul G. Savas, Judy S. Slotkin and James J. Antal will be appointed to serve on the Audit Committee. Compensation Committee. The Compensation Committee, which currently consists of directors Paul G. Savas, Mehmet C. Oz and Michael A. Weiner, held no meetings during 2003. All actions by this committee in 2003 were taken by unanimous written consent of its members. The Compensation Committee functions include reviewing and approving the compensation and benefits for SIGA's executive officers, administering SIGA's stock plans and making recommendations to the Board of Directors regarding these matters. It is anticipated that after the Annual Meeting Donald G. Drapkin, Paul G. Savas and Mehmet C. Oz will be appointed to serve on the Compensation Committee. Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee (the "Nominating Committee"), which currently consists of directors Paul G. Savas, Mehmet C. Oz and Michael A. Weiner, was formed in March 2004 and as such held no meetings in 2003. The Nominating Committee is responsible for searching for and recommending to the Board of Directors potential nominees for director positions, making recommendations to the Board of Directors regarding the size and composition of the Board of Directors and its committees, monitoring the Board of Director's effectiveness and developing and implementing the SIGA's corporate governance procedures and policies. It is anticipated that after the Annual Meeting Judy S. Slotkin, James J. Antal and Michael A. Weiner will be appointed to serve on the Nominating and Corporate Governance Committee. In selecting candidates for the Board of Directors, the Nominating Committee begins by determining whether the incumbent directors whose terms expire at the annual meeting of stockholders desire and are qualified to continue their service on the Board of Directors. SIGA is of the view that the continuing service of qualified incumbents promotes stability and continuity in the board room, giving SIGA the benefit of the familiarity and insight into the SIGA's affairs that its directors have accumulated during their tenure, while contributing to the Board of Director's ability to work as a collective body. Accordingly, it is the policy of the Nominating Committee, absent special circumstances, to nominate qualified incumbent directors who continue to satisfy the Nominating Committee's criteria for membership on the Board of Directors, whom the Nominating Committee believes will continue to make important contributions to the Board of Directors and who consent to stand for re-election and, if re-elected, to continue their service on the Board of Directors. If there are positions on the Board of Directors for which the Nominating Committee will not be re-nominating an incumbent director, or if there is a vacancy on the Board of Directors, the Nominating Committee will solicit recommendations for nominees from persons whom the Nominating Committee believes are likely to be familiar with qualified candidates, including members of the Board of Directors and management of SIGA. The Nominating Committee may also engage a professional search firm to assist in the identification of qualified candidates, but did not do so in 2003. As to each recommended candidate that the Nominating Committee believes merits serious consideration, the Nominating Committee will collect as much information, including without limitation, soliciting views from other directors and SIGA's management and having one or more Nominating Committee members interview each such candidate, regarding each candidate as it deems necessary or appropriate in order to make an informed decision with respect to such candidate. Based on all available information and relevant considerations, the Nominating Committee will select, for each directorship to be filled, a candidate who, in the view of the Nominating Committee, is most suited for membership on the Board of Directors. In making its selection, SIGA will evaluate candidates proposed by stockholders under criteria similar to the evaluation of other candidates, except that the Nominating Committee may consider, as one of the factors in its -6- evaluation of stockholder recommended nominees, the size and duration of the interest of the recommending stockholder or stockholder group in the equity of SIGA. This consideration may also include how long the recommending stockholder intends to continue holding its equity interest in SIGA. The Nominating Committee has adopted a policy with regard to the minimum qualifications that must be met by a Nomination Committee-recommended nominee for a position on SIGA's Board of Directors, which policy is described in this paragraph. The Nominating Committee generally requires that all candidates for the Board of Directors be of high personal integrity and ethical character. The Nominating Committee requires that candidates not have any interests that would, in the view of the Nominating Committee, materially impair his or her ability to (i) exercise independent judgment or (ii) otherwise discharge the fiduciary duties owed as a director to SIGA and its stockholders. In addition, candidates must be able to represent fairly and equally all stockholders of SIGA without favoring or advancing any particular stockholder or other constituency of SIGA. Candidates must have demonstrated achievement in one or more fields of business, professional, governmental, communal, scientific or educational endeavor. Candidates are expected to have sound judgment and a general appreciation regarding major issues facing public companies of a size and operational scope similar to SIGA, including contemporary governance concerns, regulatory obligations of a public issuer, strategic business planning, competition in a global economy, and basic concepts of corporate finance. Candidates must also have, and be prepared to devote, adequate time to the Board and its committees. It is expected that, taking into account their other business and professional commitments, including their service on the boards of other companies, each candidate will be available to attend meetings of the Board and any committees on which the candidate will serve, as well as SIGA's annual meeting of stockholders. SIGA also requires that at least a majority of the directors serving at any time on the Board are independent, as defined under the rules of the NASDAQ stock market and that at least three of the directors satisfy the financial literacy requirements required for service on the Audit Committee under the rules of the NASDAQ stock market. The Nominating Committee has adopted a policy with regard to the consideration of director candidates recommended by stockholders, the material elements of which policy are described in this paragraph. The Nominating Committee will consider recommendations for nomination for director submitted by holders of SIGA's shares entitled to vote generally in the election of directors. The Nominating Committee will give consideration to these recommendations for positions on the Board where the Nominating Committee has not determined to re-nominate a qualified incumbent director. While the Nominating Committee has not established a minimum number of shares that a stockholder must own in order to present a nominating recommendation for consideration, or a minimum length of time during which the stockholder must own its shares, the Nominating Committee may take into account the size and duration of a recommending stockholder's ownership interest in SIGA. The Nominating Committee may also consider whether the stockholder making the nominating recommendation intends to maintain an ownership interest in SIGA of substantially the same size as at its interest at the time of making the recommendation. The Nominating Committee may refuse to consider recommendations of nominees who do not satisfy the minimum qualifications prescribed by the Nominating Committee for board candidates. The Nominating Committee has adopted procedures to be followed by stockholders in submitting recommendations of candidates for director. The procedures are posted on SIGA's website at www.siga.com under the "Corporate Governance" section, and described in this paragraph. A stockholder (or group of stockholders) wishing to submit a nominating recommendation for an annual meeting of stockholders should try to ensure that it is received by SIGA, as provided herein, not later than 120 calendar days prior to the first anniversary of the date of the proxy statement for the prior annual meeting of stockholders. All stockholder nominating recommendations should be in writing, addressed to "the Nominating and Corporate Governance Committee" care of SIGA's Chief Financial Officer at SIGA's principal headquarters, 420 Lexington Avenue, Suite 601, New York, New York 10170. Submissions should be made by mail, courier or personal delivery. A nominating recommendation should be accompanied by the following information concerning each recommending stockholder: o The name and address, including telephone number, of the recommending stockholder; o The number and class of SIGA's shares owned (beneficially or of record) by the recommending stockholder and the time period for which such shares have been held; -7- o A statement from the stockholder as to whether the stockholder has a good faith intention to continue to hold the reported shares through the date of SIGA's next annual meeting of stockholders; o Sufficient information about the proposed nominee for the Nominating Committee to make an informed decision regarding the qualifications of the proposed nominee; o Any relationship between the proposed nominee and the recommending stockholder; and o Such other information as the Nominating Committee may reasonably request. The nominating recommendation must be accompanied by the consent of the proposed nominee to be interviewed by the Nominating Committee, if the Nominating Committee chooses to do so in its discretion (and the recommending stockholder must furnish the nominee's contact information for this purpose), and, if nominated and elected, to serve as a director of SIGA. Code of Ethics SIGA has adopted a code of ethics and business conduct that applies to its officers, directors and employees, including without limitations, our Chief Executive Officer, President, Chief Financial Officer and Chief Scientific Officer. The Code of Ethics and Business Conduct is available on SIGA's website at www.siga.com under the "Corporate Governance" section. Stockholder Communications with the Board of Directors SIGA stockholders may send communications to the Board, any committee of the Board or an individual director. The process for so communicating is posted on SIGA's website at www.siga.com under the "Corporate Governance" section. Audit Committee Report The members of the Audit Committee have been appointed by the Board of Directors. During the 2003 fiscal year, the Audit Committee consisted solely of independent directors, as defined in Rule 4200(a)(15) of the NASD Marketplace Rules. The Audit Committee operates under a written charter that was amended and restated by the Board of Directors in March 2004 in order to assure continued compliance by SIGA with SEC and NASDAQ rules enacted in response to requirements of the Sarbanes-Oxley Act. The Audit Committee assists the Board of Directors in monitoring the integrity of SIGA's financial statements, the independent registered public accounting firm's qualifications and independence, the performance of the independent registered public accounting firm, and the compliance by SIGA with legal and regulatory requirements. Management is responsible for SIGA's internal controls and the financial reporting process. The independent registered public accounting firm is responsible for performing an independent audit of SIGA's financial statements in accordance with generally accepted auditing standards and for issuing a report on those financial statements. The Audit Committee monitors and oversees these processes. In this context, the Audit Committee has reviewed and discussed the audited financial statements for the year ended December 31, 2003 with management and with PricewaterhouseCoopers LLP, SIGA's independent registered public accounting firm. The Audit Committee has discussed with PricewaterhouseCoopers LLP the matters required to be discussed by Statement on Auditing Standards No. 61 (Communications with Audit Committees), which includes, among other items, matters related to the conduct of the audit of SIGA's annual financial statements. The Audit Committee has also received the written disclosures and the letter from PricewaterhouseCoopers LLP required by Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees) and has discussed with PricewaterhouseCoopers LLP the issue of their independence from SIGA and management. In addition, the Audit Committee has considered whether the provision of non-audit services by the independent registered public accounting firm in 2003 is compatible with maintaining the auditors' independence and has concluded that it is. -8- Based on its review of the audited financial statements and the various discussions noted above, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in SIGA's Annual Report on Form 10-KSB for the year ended December 31, 2003. The Audit Committee has also recommended, subject to stockholder ratification, the selection of SIGA's independent registered public accounting firm for the year ending December 31, 2004. The members of the Audit Committee are Paul G. Savas, Dr. Mehmet C. Oz and Dr. Michael A. Weiner, none of whom is or, during the fiscal year 2003, was, an employee of SIGA.

Long-Term Incentive Plans--Awards in Last Fiscal Year As of January 1, 1996, we adopted our 1996 Incentive and Non-Qualified Stock Option Plan. An amendment and restatement of such plan, as amended, was adopted on May 3, 2001 and was further refined by the Board of Directors on June 29, 2001 (the "Plan"). The Plan was approved by our stockholders at an annual meeting on August 15, 2001. Stock options may be granted to key employees, consultants and outside directors pursuant to the Plan. The Plan was amended again at our annual meeting on January 8, 2004, when our stockholders voted to increase the maximum number of shares of common stock available for issuance under the Plan from 7,500,000 to 10,000,000. The Plan is administered by our Compensation Committee which determines persons to be granted stock options, the amount of stock options to be granted to each such person, and the terms and conditions of any stock options as permitted under the Plan. The members of the Compensation Committee are Mehmet C. Oz, M.D., Paul G. Savas and Michael A. Weiner, M.D. See "Committees of the Board of Directors" above for more information. Both Incentive Options and Nonqualified Options may be granted under the Plan. An Incentive Option is intended to qualify as an incentive stock option within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"). Any Incentive Option granted under the Plan will have an exercise price of not less than 100% of the fair market value of the shares on the date on which such option is granted. With respect to an Incentive Option granted to an employee who owns more than 10% of the total combined voting stock of SIGA or of any parent or subsidiary of SIGA, the exercise price for such option must be at least 110% of the fair market value of the shares subject to the option on the date the option is granted. The Plan, as amended, provides for the granting of options to purchase 10,000,000 shares of common stock, of which 6,460,811 options were outstanding as of December 31, 2003. During the fiscal year ending December 31, 2003, the named Directors and Officers of SIGA received long-term incentive compensation under the Plan as shown in the following table. -12- Estimated Future Payouts Under Non-Stock Price Based Plans ------------------------------------- (a) (b) (c) (d) (e) (f) Number of Shares, Performance or Units or Other Other Period Until Rights Maturation of Threshold Target Maximum Name (#) Payout ($ or #) ($ or #) ($ or #) ---- ----------------- ------------------ ----------- ------------ ------------ Susan K.

Kasten, Jr., M.D. 100,000 5/23/13 N/A N/A N/A Employment Contracts and Directors Compensation Directors' Compensation In 2003, SIGA did not pay fees to its directors, nor did it reimburse its directors for expenses incurred. In November 2004, the Compensation Committee recommended and the Board of Directors approved the following director compensation program: o Directors will receive $1,000 per meeting for board meetings and will be reimbursed for expenses incurred by them in connection with serving on our Board of Directors. o The chairman of the Audit Committee will receive $1,000 per meeting for meetings of the Audit Committee and all other members of the Audit Committee will receive $500 per meeting for meetings of the Audit Committee. o Members of Compensation Committee will receive $500 per meeting for meetings of the Compensation Committee. o Non-employee directors will receive an initial grant of 25,000 options, upon such non-employee director's first election to the Board of Directors, which such options will be granted under SIGA's Amended and Restated 1996 Incentive and Non-Qualified Stock Option Plan. Given that certain of our directors have been appointed to the Board of Directors during interim periods and have not received, to date, any option grants as directors, the Compensation Committee has recommended and the Board of Directors have approved that such initial grants be made to Adnan M. Mjalli, Ph.D. , Paul G. Savas, Judy S. Slotkin, and James J. Antal, as of the 2004 Annual Meeting. All such options have an exercise price equal to the fair market value of the underlying SIGA shares on the date of grant. o In addition, non-employee directors will receive an annual grant of 10,000 options under SIGA's Amended and Restated 1996 Incentive and Non-Qualified Stock Option Plan, made at each Annual Meeting and commencing with the 2005 Annual Meeting. All such options have an exercise price equal to the fair market value of the underlying SIGA shares on the date of grant. Employment Contracts Dr. Bernard L.

PricewaterhouseCoopers LLP has audited SIGA's financial statements since January 1997. Representatives of PricewaterhouseCoopers LLP are expected to be present at the Annual Meeting and will have the opportunity to make a statement if they desire to do so, and are expected to be available to respond to appropriate questions. The affirmative vote of a majority of the total votes cast on such proposal in person or by proxy at the Annual Meeting will be required to ratify the selection of PricewaterhouseCoopers LLP. If the stockholders fail to ratify the selection, the Audit Committee will reconsider its selection of auditors. Even if the selection is ratified, the Audit Committee, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time during the year, if it determines that such change would be in the best interests of SIGA and its stockholders. Audit Fees PricewaterhouseCoopers LLP billed SIGA $203,150 in the aggregate, for professional services rendered by them for the audit of SIGA's annual financial statements for the fiscal year ended December 31, 2003, reviews of the interim financial statements included in SIGA's forms 10-QSB filed during the year ended December 31, 2003 and consents and reviews of various documents filed with the SEC during the year ended December 31, 2003. PricewaterhouseCoopers LLP billed SIGA $101,580 in the aggregate, for professional services rendered by them for the audit of SIGA's annual financial statements for the fiscal year ended December 31, 2002, and the reviews of the interim financial statements included in SIGA's forms 10-QSB filed during the year ended December 31, 2002. Audit Related Fees PricewaterhouseCoopers LLP billed SIGA $62,700 in the aggregate for audit and related services rendered with regard to its acquisition of substantially all the assets of Plexus Vaccine Inc. during the fiscal year ended December 31, 2003. PricewaterhouseCoopers LLP billed SIGA $255,690 in the aggregate for assurance and related services rendered primarily with regard to its proposed acquisition of Allergy Therapeutics Holdings Ltd. during the fiscal year ended December 31, 2002. Tax Fees PricewaterhouseCoopers LLP did not render any professional services for tax compliance, tax advice or tax planning during either of the fiscal years ended December 31, 2003 or December 31, 2002. All Other Fees PricewaterhouseCoopers LLP did not provide any products or render any professional services (other than those covered above under "Audit Fees," "Audited Related Fees," and "Tax Fees") during either of the fiscal years ended December 31, 2003 or December 31, 2002. -21- Policy on Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services of Independent Registered Public Accounting Firm The Audit Committee's policy is to pre-approve all audit and permissible non-audit services provided by the independent registered public accounting firm. These services may include audit services, audit-related services, tax services, and other services. SIGA did not make use in fiscal year 2003 of the rule that waives pre-approval requirements for non-audit services in certain cases if the fees for these services constitute less than 5% of the total fees paid to the auditor during the year. THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE "FOR" THE RATIFICATION (ITEM 2 OF THE ENCLOSED PROXY CARD) OF THE APPOINTMENT OF PRICEWATERHOUSECOOPERS LLP AS SIGA'S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2004. -22- STOCKHOLDER PROPOSALS Stockholder proposals to be presented at the 2005 Annual Meeting of Stockholders, for inclusion in SIGA's proxy statement and form of proxy relating to that meeting, must be received by SIGA at its offices in New York, New York, addressed to the Secretary, not later than July 5, 2005. Such proposals must comply with SIGA's By-Laws and the requirements of Regulation 14A of the Securities Exchange Act of 1934 (the "Exchange Act"). In addition, Rule 14a-4 of the Exchange Act governs SIGA's use of its discretionary proxy voting authority with respect to a stockholder proposal that is not addressed in the proxy statement. With respect to SIGA's 2005 Annual Meeting of Stockholders, if SIGA is not provided notice of a stockholder proposal prior to September 20, 2005, SIGA will be allowed to use its discretionary voting authority when the proposal is raised at the meeting, without any discussion of the matter in the proxy statement. SECTION 16 BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Section 16(a) of the Exchange Act requires SIGA's officers and directors, and persons who own more than ten percent of a registered class of SIGA's equity securities, to file reports of ownership and changes in ownership with the Securities and Exchange Commission. Officers, directors and greater than ten-percent stockholders are required by Securities and Exchange Commission regulation to furnish SIGA with copies of all Section 16(a) reports that they file. Based solely upon review of the copies of such reports furnished to SIGA and written representations from certain of SIGA's executive officers and directors that no other such reports were required, SIGA believes that during the fiscal year ended December 31, 2003, all Section 16(a) filing requirements applicable to its officers, directors and greater than ten-percent beneficial owners were complied with on a timely basis. AVAILABILITY OF ANNUAL REPORT AND FORM 10-K TO STOCKHOLDERS SIGA's Annual Report to Stockholders for the year ended December 31, 2003 accompanies this proxy statement. SIGA will provide to any stockholder, upon written request and without charge, a copy of its most recent Report on Form 10-KSB, including the financial statements, as filed with the Securities and Exchange Commission. All requests for such reports should be directed to the Chief Financial Officer, 420 Lexington Avenue, Suite 601, New York, New York 10170, telephone number (212) 672-9100. OTHER MATTERS At the date of this proxy statement, management was not aware that any matters not referred to in this proxy statement would be presented for action at the Annual Meeting.
