Konatich Secretary New York, New York April 27, 2007 SIGA Technologies, Inc. 420 Lexington Avenue, Suite 408 New York, New York 10170 -------------- PROXY STATEMENT ANNUAL MEETING OF STOCKHOLDERS MAY 30, 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 Annual Meeting of Stockholders (the "Annual 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 Wednesday, May 30, 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 April 27, 2007. 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 April 25, 2007 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 33,014,410 shares of common stock, par value $.0001 per share ("Common Stock"). Voting at the Annual Meeting Each share of Common 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, 2007, the affirmative vote of a majority of the total votes 1 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, 2007; 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 of soliciting proxies. 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.

In addition, actions were taken during 2006 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. Seven members of the Board of Directors attended SIGA's 2006 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. Audit Committee. The Audit Committee, which currently consists of directors Paul G. Savas, Judy S. Slotkin and James J. Antal, held ten meetings during 2006. The Board of Directors has determined that each of the members of the Audit Committee is "independent" under the applicable laws, rules and regulations. The Company has determined that Mr. Savas is an "Audit Committee financial expert" within the meaning of Regulation S-K promulgated by the Securities and Exchange Commission (the "SEC"). 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. A copy of the Audit Committee charter is available on SIGA's website at www.siga.com under the "Corporate Governance" section. Also see the section of this proxy statement entitled "Report of the Audit Committee." 5 Compensation Committee. The Compensation Committee, which currently consists of directors Donald G. Drapkin, Paul G. Savas and Michael A. Weiner, held one meeting during 2006. The Board of Directors has determined that each of the members of the Compensation Committee is "independent" within the meaning of the NASDAQ listing standards. 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. A copy of the Compensation Committee charter is available on SIGA's website at www.siga.com under the "Corporate Governance" section. Also see the section of this proxy statement entitled "Compensation Discussion and Analysis." Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee (the "Nominating Committee"), which currently consists of directors Judy S. Slotkin, James J. Antal and Michael A. Weiner, was formed in March 2004 and held three meetings in 2006. On December 19, 2006, the Board of Directors elected Dr. Weiner to replace Mehmet C. Oz. The Board of Directors has determined that each of the members of the Nominating Committee is "independent" within the meaning of the NASDAQ listing standards. 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 SIGA's corporate governance procedures and policies. A copy of the Nominating and Corporate Governance Committee charter is available on SIGA's website at www.siga.com under the "Corporate Governance" section. 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 of the board, giving SIGA the benefit of the familiarity and insight into 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 2006. 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 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 6 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 408, 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; 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. Compensation Committee Interlocks and Insider Participation None. 7 Code of Ethics SIGA has adopted a code of ethics and business conduct that applies to its officers, directors and employees, including without limitation, our Chief Executive Officer, 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. 8 REPORT OF THE AUDIT COMMITTEE The members of the Audit Committee have been appointed by the Board of Directors. During the 2006 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, 2006 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, as amended (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 2006 is compatible with maintaining the auditors' independence and has concluded that it is. 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-K for the year ended December 31, 2006. 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, 2007. The members of the Audit Committee are Paul G. Savas, Judy S. Slotkin and James J. Antal, none of whom is or, during the fiscal year 2006, was, an employee of SIGA. Respectfully submitted by the Audit Committee, Paul G. Savas, Chairman James J. Antal Judy S. Slotkin 9 COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION The Compensation Committee, comprised of independent directors, has: (1) reviewed and discussed the Compensation Discussion and Analysis included in this proxy statement with management; and (2) based on the review and discussions referred to in paragraph (1) above, the Compensation Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in the Company's proxy statement relating to the 2007 Annual Meeting of shareholders.

COMPENSATION DISCUSSION AND ANALYSIS Overview The Compensation Committee of the Board of Directors is responsible for implementing the Board's directives relating to the compensation of our named executive officers, as well as our other key employees. In this regard, the Compensation Committee has the responsibility to establish a compensation policy for officers and key employees designed to (i) attract and retain the best possible executive talent; (ii) tie annual and long term cash and stock incentives to achievement of measurable corporate and individual performance objectives; and (iii) provide competitive compensation to our officers and key employees to align executives' incentives with the creation of stockholder value. 14 As a general matter, the compensation policy for officers and key employees includes: o base salary, which is determined on an annual or semi-annual basis o annual or other time-based cash incentive compensation, and o long-term incentive compensation in the forms of equity participation awards. This section discusses the principles underlying our executive compensation policies, our decisions to date and the principles that we expect to use in coming years. Our Named Executive Officers For 2006, our Named Executive Officers and their titles were: Name Title Dr. Bernard L. Kasten Chief Executive Officer(1) Thomas N. Konatich Acting Chief Executive Officer(2) & Vice President, Chief Financial Officer, Secretary and Treasurer Dr. Dennis E. Hruby Chief Scientific Officer and Vice President Dr. Eric A. Rose Chief Executive Officer(3) and Chairman of the board (1) From July 2, 2004 through April 30, 2006. (2) From May 1, 2006 through February 28, 2007. (3) On March 1, 2007, Dr. Eric A. Rose became our Chief Executive Officer. Our Executive Compensation Decision Process Overview Our Compensation Committee reviews and approves on a periodic basis the corporate goals and objectives with respect to the compensation for the chief executive officer and other executive officers. Role of Executive Officers in Setting Compensation Decisions Regarding most compensation matters, the Chief Executive Officer has historically provided recommendations to the Compensation Committee relying on his personal experience with respect to evaluating the contribution of our other executive officers. We anticipate that Dr. Eric A. Rose, currently our Chief Executive Officer and Chairman of the Board will be involved in compensation recommendations, with input from our Chief Financial Officer and Chief Scientific Officer, as it relates to the compensation of other key employees. The Compensation Committee considers, but retains the right to reject or modify such recommendations. Although the Chief Executive Officer may attend a portion of the meetings of the Compensation Committee, neither he nor any other member of management may be present during executive sessions of the Compensation Committee. Moreover, the Chief Executive Officer may not be present when decisions with respect to his compensation are made. The Committee has used, on more than one occasion, a third party compensation consultant. Compensation Advisors The Compensation Committee has the authority to retain compensation consultants to advise the Compensation Committee as it deems necessary to carry out its duties. Competitive Market Analysis and Benchmarking In reviewing and recommending the compensation of the Chief Executive Officer and other executive officers, the Compensation Committee considers the compensation awarded to officers of similarly situated companies, our performance, the individuals' performance, compensation given to our officers in past years or any other factor the Compensation Committee deems appropriate. 15 Evaluations The Compensation Committee evaluates at least once a year the performance of our officers and other key employees in light of goals and objectives established by the Committee and based upon these evaluations the Compensation Committee recommends to the full Board of Directors, the annual compensation for our officers and key employees, including base salary, bonus, incentive and equity compensation. Our Compensation Philosophy and Program Objectives The overall objectives of the Company's compensation program are to attract and retain the best possible executive talent, to motivate these executives to achieve the goals inherent in the Company's business strategy, to maximize the link between executive and stockholder interests through a stock option plan and to recognize individual contributions as well as overall business results. To achieve these objectives, the Company has developed an overall compensation strategy and specific compensation plans that tie a substantial portion of an executive's compensation to performance. Our Executive Compensation Program Overview The key elements of the Company's compensation program consist of fixed compensation in the form of base salary, and the discretion to award variable compensation in the forms of annual incentive compensation and stock option awards. The Compensation Committee's policies with respect to each of these elements are discussed below. In addition, while the elements of compensation described below are considered separately, the Compensation Committee takes into account the full compensation package offered by the Company to the individual, including pension benefits, insurance and other benefits, as well as the programs described below. Base Salary The compensation philosophy of the Company is to maintain executive base salary at a competitive level to enable the Company to attract and retain executives and key employee talent needed to accomplish the Company's goals. In determining the appropriate base salary levels and, to a lesser extent, other compensation elements, the Compensation Committee considers the scope of responsibility, prior experience and past accomplishments, as well as historical practices within the Company. Economic and business conditions affecting the Company are also considered. The Compensation Committee also considers historical levels of salary paid by the Company as well as the provisions in the various executive's employment contracts with the Company, which contracts are more fully discussed elsewhere in this proxy statement. Periodic adjustments in base salary may be merit based with respect to individual performance or tied to the Company's financial condition or other competitive factors. The Compensation Committee takes into account the effect of any corporate transactions that have been consummated during the relevant year and, where appropriate, also considers non-financial performance measures. These include the Company's market share, scientific developments and improvements in relations with employees and investors. For Mr. Konatich and Dr. Hruby, we paid as base salary in 2006 the amounts required under their employment agreements. These amounts were reviewed and set by our Compensation Committee. These base salary levels reflect our Compensation Committee's subjective judgment, which took into account each executive's respective position and tenure, our present needs, the executive's individual performance, achievements and prior contributions. For Dr. Kasten, we paid the amounts required by various agreements to which we and he are parties and which, in all instances, where reviewed and approved by the Compensation Committee. Annual Incentive Compensation The Compensation Committee, in its discretion, may establish cash incentive programs and otherwise award bonuses to executive officers and key employees. Annual incentive compensation to our executive officers is payable pursuant to contractual provisions with certain executives which provide eligibility to receive discretionary bonuses, in the sole discretion of the Board of Directors based on the executives performance, economic and business conditions affecting the Company, and the financial condition of the Company. The Compensation Committee makes recommendations to the Board of Directors with respect to such amounts. In addition, Dr. Hruby and Mr. Konatich are contractually entitled to certain guaranteed cash bonus payments each year. The annual incentive compensation earned by the executives with respect to 2006 was discretionary and determined by the Compensation Committee. We believe that the annual incentive bonuses motivate and encourage our executives to fulfill our objectives and provide us with the opportunity to recognize superior individual performance. 16 For 2006, both Mr. Konatich and Dr. Hruby were eligible for annual cash bonuses. In the case of Mr. Konatich, his annual cash bonus was $60,000 and for Dr. Hruby his annual cash bonus was $62,500. Long-Term Incentive Awards The Compensation Committee believes that granting stock options on an ongoing basis provides officers and key employees with strong economic interest in maximizing stock price appreciation over the long term. We believe that the practice of granting stock options is critical to retaining and recruiting the key talent necessary at all employee levels to ensure the Company's continued success. This element of compensation is governed by the Amended and Restated 1996 Incentive and Non-Qualified Stock Option Plan (the "Option Plan") that provides for grants of incentive stock options and non-qualified stock options to our executives, directors and key employees. The Option 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 exercise price of stock options is set by the Compensation Committee and has been at a price at least equal to the market price of the common stock on the date of the grant. The options therefore do not have any value to the executive unless the market price of the common stock rises, which ensures that the interests of our executives are aligned with those of our shareholders. Through these option grants, we seek to emphasize the importance of improving the performance of our stock price, increasing shareholder value over the long-term. Both Incentive Options and Nonqualified Options may be granted under the Option 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"). As such, 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. In determining the size of an option grant to a named executive officer, the Compensation Committee considers not only competitive market factors, changes in responsibility and the executive officers' achievement of pre-established goals, but also the number, term and vesting of options previously granted to the officer. The Compensation Committee may also consider the total compensation package or changes made thereto, when determining whether to make an option award. During the year ended December 31, 2006 the Compensation Committee did not authorize awards of options to the officers of the Company. Additional Benefits and Perquisites Our officers and key employees are entitled to participate in the benefit plans which are generally available to all employees, including health, dental, life, and accidental disability. For each of these benefit plans, the Company makes contributions to the premiums paid to the plans. The Company also offers a 401(k) defined contribution plan, however, the Company does not make any contribution to the 401(k) plan. In each case, we provide these benefits to our executive officers on the same basis as our other employees. Severance and Change-in-Control Agreements Finally, we also provide some of our executive officers with severance and change-in-control arrangements in their employment contracts. We believe that severance and change of control packages are a common characteristic of compensation for key executive officers. They are intended to provide our executive officers with a sense of security in making the commitment to dedicate their professional career to our success. Due to our size relative to other public companies and our operating history, we believe that severance and change-in-control arrangements are necessary to help us attract and retain necessary skilled and qualified executive officers to continue to grow our business. As described elsewhere in this proxy statement, Dr. Kasten, our former Chief Executive Officer, entered into an arrangement with the Company in connection with his resignation. Our Compensation Policies Section 162(m) Policy The Compensation Committee attempts to ensure full deductibility of compensation notwithstanding the limitation on the deductibility of certain compensation in excess of one million dollars under Section 162(m) of the Code. 17 The Company's stock options are designed so as to cause stock options and bonuses granted there under to be exempt from the limitations contained in Section 162(m) of the Code. Common Share Ownership Requirements While we have not adopted a formal written policy on common share ownership requirements, part of our compensation philosophy involves common share ownership by our executive officers, because we believe that it helps to align their financial interests with those of our shareholders. We also recognize, on the other hand, that our executive officers cannot acquire more than 10% of our common shares without triggering adverse tax consequences. In addition, we expect our executive officers to abide by the provisions of our 2004 Policy on Confidential Information and Insider Trading. Timing of Awards Our Compensation Committee has the authority to issue equity awards under our Amended and Restated 1996 Incentive and Non-Qualified Option Plan. We expect that the Compensation Committee will continue making ongoing annual option awards to our executive officers and key employees. The Compensation Committee strives to ensure that any award is made in such a manner to avoid even the appearance of manipulation because of its award date. 18 Summary Compensation Table The following table sets forth the total compensation of the Company's Named Executive Officers for the fiscal year ended December 31, 2006.

Option Awards 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, and amended on January 8, 2004, to increase the maximum number of shares of common stock available for issuance under the Plan to 10,000,000. 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 May 26, 2005, when our stockholders voted to increase the maximum number of shares of common stock available for issuance under the Plan from 10,000,000 to 11,000,000. 19 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 Michael A. Weiner, M.D., Paul G. Savas and Donald G. Drapkin. 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 11,000,000 shares of common stock, of which 7,546,145 options were outstanding as of December 31, 2006. 20 All Other Compensation The amount reported in the "All Other Compensation" reflects payments made to Dr. Kasten under his Separation Agreement with the Company, dated March 31, 2006. Grants of Plan Based Awards No options or other grants of plan based awards were granted during the year ended December 31, 2006 to any named executive officer in their capacity as such; however, Dr. Eric A. Rose, who became our Chief Executive Officer on March 1, 2007, received an award of an option to purchase 10,000 shares of our common stock on December 19, 2006, in his capacity as a director of SIGA. Please see the section entitled "Directors' Compensation" below for a description of Dr. Rose's option award. Employment Agreements We currently have employment agreements with Dr. Rose, Mr. Konatich and Dr. Hruby. These agreements became effective as of March 1, 2007 in the case of Dr. Rose and January 22, 2007 in the case of Mr. Konatich and Dr. Hruby. In fiscal year 2006, Mr. Konatich and Dr. Hruby were employed under prior employment agreements (which the current agreements amend and restate). In addition, we had an employment agreement with our former Chief Executive Officer, Dr. Bernard L. Kasten, during his term of employment. We have included below descriptions of the current employment agreements and those in effect as of December 31, 2006. As we believe that the current agreements are the most relevant for an understanding of the current arrangements with our named executive officers, we have included them first. However, we follow the current descriptions with descriptions of the prior agreements in place as of December 31, 2006, so that the relevant information is available for those matters in this proxy statement that are required to be disclosed as of December 31, 2006. Eric A. Rose - Chief Executive Officer On January 31, 2007, we entered into an employment agreement with Dr. Eric A. Rose, M.D., pursuant to which he became our Chief Executive Officer, effective as of March 1, 2007. The employment agreement expires on February 29, 2008, and, unless either party provides thirty (30) days notice prior to the end of the term, shall automatically renew for additional one (1) year periods thereafter. Pursuant to the employment agreement, we agree to pay to Dr. Rose an annual base salary of $400,000, subject to any cost of living adjustments as may be approved by our Board. Dr. Rose is also eligible to receive bonus payments (in either cash or stock options) as may be approved by the Board in its sole discretion. We may terminate his employment agreement (with or without cause), provided that upon any termination by us without cause (including, without limitation, termination without cause upon a change in control), or termination by Dr. Rose for 21 good reason, we will be obligated to continue to pay Dr. Rose's base salary for one year, and all stock options and other stock-based grants to Dr. Rose shall immediately and irrevocably vest and become exercisable upon the date of termination and shall remain exercisable for a period of not less than one (1) year from the date of termination. Further detail on our severance obligations to Dr. Rose, including the definitions of "cause," "good reason" and "change in control" is set forth below under the heading "Potential Payments Upon Termination or Change-in-Control." Thomas N. Konatich - Chief Financial Officer On January 22, 2007, we entered into an amended and restated employment agreement with Thomas N. Konatich, our Chief Financial Officer, which replaced his prior employment agreement (which agreement is described in the following paragraph). Mr. Konatich also serves as our Vice President, Secretary and Treasurer, and from May 1, 2006 through February 28, 2007 served as our Acting Chief Executive Officer. The current employment agreement expires on January 22, 2009, and, unless either party provides thirty (30) days notice prior to the end of the term, shall automatically renew for additional one (1) year periods thereafter. Pursuant to the employment agreement, we agree to pay to Mr. Konatich an annual base salary of $250,000, subject to any cost of living adjustments as may be approved by our Board, and an annual cash bonus of $60,000. Mr. Konatich is also eligible to receive such additional bonus payments (in either cash or stock options) as may be approved by our Board in its sole discretion. We may terminate his employment agreement (with or without cause), provided that upon any termination by us without cause (including, without limitation, termination without cause upon a change in control), or termination by Mr. Konatich for good reason, we will be obligated to continue to pay Mr. Konatich's base salary for two (2) years, and all stock options and other stock-based grants to Mr. Konatich shall immediately and irrevocably vest and become exercisable upon the date of termination and shall remain exercisable for a period of not less than one (1) year from the date of termination. Previously, Mr. Konatich was employed by SIGA under an employment agreement dated April 1, 1998, as amended on January 19, 2000, as amended and restated on October 6, 2000, as amended on each of January 31, 2002, November 5, 2002, July 29, 2004 and February 1, 2006. Mr. Konatich received an annual base salary of $230,000 and received a one-time payment of $50,000 for prior service as Acting Chief Executive Officer (which duties concluded on July 2, 2004). Mr. Konatich served as the Company's Chief Executive Officer from May 1, 2006 through February 28, 2007. His employment agreement provided for an additional bonus payment at the discretion of the Board of Directors and not to exceed twenty five percent (25%) of his annual base salary amount. He received options to purchase 95,000 shares of common stock, at $4.44 on April 1, 1998. The options vested on a pro rata basis on the first, second, third and fourth anniversaries of the agreement. On January 19, 2000, he received an additional grant to purchase 100,000 shares at an exercise price of $2.00 per share. These options vested on a pro rata basis each quarter through January 19, 2002. On January 31, 2002, Mr. Konatich was granted an Incentive Stock Option to purchase 50,000 shares at an exercise price of $3.94 per share. Such options vested in eight equal quarterly installments beginning on April 20, 2002. On November 5, 2002, Mr. Konatich was granted an Incentive Stock Option to purchase 150,000 shares at an exercise price of $2.50 per share. 75,000 of these options vested immediately and 75,000 options vested on September 1, 2003. On July 29, 2004, Mr. Konatich was granted an Incentive Stock Option to purchase 150,000 shares at an exercise price of $1.40 per share. 75,000 of these options vested immediately, with the remaining 75,000 options vesting on a pro rata basis from January 1, 2005 through December 31, 2005, with no provision for acceleration under any circumstances. Mr. Konatich was also eligible to receive additional stock options and bonuses at the discretion of the Board of Directors. SIGA was permitted to terminate the employment agreement with or without cause (as such term was defined in his employment agreement), provided that upon any termination without cause, SIGA would have been obligated to continue to pay Mr. Konatich's salary and all other amounts due under the employment agreement for the remainder of the term. If Mr. Konatich had terminated due to a change of control (as such term was defined in his employment agreement), SIGA would have been required to pay Mr. Konatich a change in control amount (as such term was defined in his employment agreement) plus his accrued and unpaid base salary, and, upon the first event constituting a change of control, all stock options and other stock-based grants to Mr. Konatich would have immediately and irrevocably vested and become exercisable upon the date of such event. Further detail on our severance obligations to Mr. Konatich, including the definitions in his current employment agreement of "cause," "good reason" and "change in control" is set forth below under the heading "Potential Payments Upon Termination or Change-in-Control." Dr. Dennis E. Hruby - Chief Scientific Officer On January 22, 2007, we entered into an amended and restated employment agreement with Dr. Dennis E. Hruby, our Chief Scientific Officer which replaced his prior employment agreement (which agreement is described in the following paragraph). The current employment agreement expires on January 22, 2010. Pursuant to the employment agreement, we agree to pay to Dr. Hruby an annual base salary of $250,000, subject to any cost of living adjustments as may be approved by our Board, and an annual cash bonus of no less than twenty-five percent (25%) and no more than fifty percent (50%) of Dr. Hruby's base salary. Dr. Hruby is also eligible to receive such additional bonus payments (in either 22 cash or stock options) as may be approved by our Board in its sole discretion. We may terminate his employment agreement (with or without cause), provided that upon any termination by us without cause (including, without limitation, termination without cause upon a change in control), or termination by Dr. Hruby for good reason, we will be obligated to continue to pay Dr. Hruby's base salary for two years, and all stock options and other stock-based grants to Dr. Hruby shall immediately and irrevocably vest and become exercisable upon the date of termination and shall remain exercisable for a period of not less than two (2) years from the date of termination. Previously, we employed Dr. Hruby under an employment agreement dated January 1, 1998, as amended on each of June 16, 2000, January 31, 2002, October 3, 2002 and July 29, 2004. This employment agreement would have expired on December 31, 2007, had the new employment agreement (discussed above) not been entered into. Dr. Hruby received a base salary of $225,000 per year, and his employment agreement also provided for additional bonus payments at the discretion of the Board of Directors and not to exceed fifty percent (50%) of his base salary amount. Dr. Hruby received options to purchase 10,000 shares of common stock at an exercise price of $5.00 per share on April 1, 1997 and 40,000 shares of common stock at an exercise price of $4.63 per share on April 1, 1998. The options became exercisable on a pro rata basis on the first, second, third and fourth anniversaries of the employment agreement. Under the June 16, 2000 amendment, Dr. Hruby was granted options to purchase 125,000 shares of SIGA's common stock at $2.00 per share. The options vested ratably over the remaining term of the amendment. The January 31, 2002 amendment changed the terms of the lock-up agreed to in the June 16, 2000 amendment to the employment agreement limiting Hruby's ability to sell SIGA stock. On January 31, 2002, Dr. Hruby was granted an Incentive Stock Option to purchase 50,000 shares at an exercise price of $3.94 per share. Such options vested in four equal annual installments beginning on August 15, 2002. As part of the October 3, 2002 amendment, Dr. Hruby was granted an option to purchase 300,000 shares of common stock. Options with respect to 75,000 shares vested upon the signing of the amendment and an additional 75,000 vested on a pro rata basis on September 1 of each 2003, 2004 and 2005. The options have an exercise price of $2.50 per share. Dr. Hruby surrendered his option to purchase up to 50,000 shares of common stock of SIGA at an exercise price of $3.94 that he was granted under an earlier amendment. On July 29, 2004, Dr. Hruby was granted an Incentive Stock Option to purchase 150,000 shares at an exercise price of $1.40 per share, which options vested in 75,000 share increments on December 31 of each year, commencing December 31, 2005. Dr. Hruby was eligible to receive additional stock options and bonuses at the discretion of the Board of Directors. SIGA was permitted to terminate the employment agreement with or without cause (as such term is defined in the employment agreement), provided that upon any termination without cause SIGA would have been obligated to continue to pay Dr. Hruby's salary for the remainder of the term. In addition, SIGA had the right to terminate Dr. Hruby's employment upon one (1) year written notice with such termination being treated as a termination for cause. If Dr. Hruby was terminated due to a change of control (as such term was defined in his employment agreement), SIGA would have been required to pay Dr. Hruby a change in control amount (as such term was defined in his employment agreement) plus his accrued and unpaid base salary, and, upon the first event constituting a change of control, all stock options and other stock-based grants to Dr. Hruby would have immediately and irrevocably vested and become exercisable upon the date of such event. Further detail on our severance obligations to Dr. Hruby including the definitions in his current employment agreement of "cause," "good reason" and "change in control" is set forth below under the heading "Potential Payments Upon Termination or Change-in-Control." Dr. Bernard L. Kasten - Former Chief Executive Officer We employed Dr. Bernard L. Kasten, as SIGA's Chief Executive Officer, under an employment agreement dated July 2, 2004. Dr. Kasten received an annual base salary of $250,000 and his employment agreement also provided for additional bonus payments at the discretion of the Board of Directors. On July 2, 2004, he received options to purchase 2,500,000 shares of common stock with an exercise price of $1.30 per share, of which 500,000 shares vested on the date of grant; with respect to the next 1,000,000 shares, an additional 166,666 shares vested on the end of each six (6) month period after date of grant until the end of the sixth six (6) month period at which time 166,667 shares were to vest. Effective April 30, 2006, SIGA and Dr. Kasten reached an agreement for Dr. Kasten's resignation. In connection with such agreed upon resignation, SIGA and Dr. Kasten entered into a Separation Agreement dated March 31, 2006 (the "Separation Agreement"). Under the provisions of the Separation Agreement, Dr. Kasten received his salary on the existing terms and conditions as set forth in his employment agreement with SIGA, dated July 2, 2004 (the "Kasten Employment Agreement") in lieu of any other severance or payment, through September 16, 2006 (the "Separation Period"). Concurrently with the execution of the Separation Agreement, SIGA and Dr. Kasten also amended Dr. Kasten's Incentive Stock Option Agreement such that Dr. Kasten's "Milestone Options" (as such term is defined in the Kasten Employment Agreement) were cancelled and Dr. Kasten's "Time Vested Options" (as such term is defined in the Kasten Employment Agreement) were amended such that with respect to the Time Vested Options which had not vested as of the date of the Separation Agreement, such options will vest as follows: with respect to 166,666 shares as of July 2, 2006 and with respect to the remaining 83,334 shares, as of January 2, 2007. Time Vested Options granted to Dr. Kasten which vested prior to the date 23 of the Separation Agreement shall remain unchanged. Dr. Kasten was also permitted to continue to receive medical and/or dental insurance benefits under the relevant SIGA plans until (i) the end of the Remaining Tenure (defined as the earlier of April 30, 2006 or Dr. Kasten's obtaining new employment), (ii) he becomes entitled to Medicare or (iii) he becomes eligible for coverage under medical and/or dental insurance benefit plans, as the case may be, of another employer through his future employment, whichever occurs first. The Separation Agreement also contains mutual non-disparagement and release terms, requires that Dr. Kasten remain available to SIGA on a reasonable basis for transitional purposes during the Separation Period and requires SIGA to indemnify Dr. Kasten under the terms of its certificate of incorporation and bylaws for acts relating to his employment.

Potential Payments Upon Termination or Change in Control Severance Arrangement for Thomas N. Konatich The following table and footnotes describe and quantify the potential payments upon termination or change in control for Mr. Konatich, assuming that termination or change-in-control was effective as of December 31, 2006: Termination by the Company without cause (or by the Termination upon Termination by the officer for good death or Company due to a Thomas N. Konatich cause) disability change in control Aggregate monthly cash payments $ 249,167 $ -- $ -- Lump sum cash payment -- -- 249,167 Value of accelerated stock options -- -- -- ----------- ----------- ----------- Total $ 249,167 $ -- $ 249,167 =========== =========== =========== Pursuant to Mr. Konatich's prior employment agreement (which was in effect as of December 31, 2006), the following termination and change in control-related circumstances would trigger payments or the provision of other benefits: o Termination by the Company for cause. o Termination by the Company based on Mr. Konatich's death or disability. o Termination by the Company without cause (or by Mr. Konatich for good reason). o Termination by the Company due to a change in control. Payments Upon any Termination other than in connection with a Change in Control: If Mr. Konatich was terminated for cause or disability, or if he resigned for reasons other than a material breach by the Company of its obligations under his employment agreement, or a material reduction of his duties, or if he died, then the Company had no obligation to pay Mr. Konatich any amount, whether for salary, benefits, bonuses, or other compensation or expense reimbursements of any kind, accruing after his termination, and such rights would be, except as 25 otherwise required by law, forfeited immediately upon termination. However, payments of base salary would continue until the expiration of the employment agreement where Mr. Konatich was terminated for death or disability. If the Company had terminated Mr. Konatich without cause, then the Company would have been obligated to continue to pay Mr. Konatich's salary and all other amounts due under the employment agreement for the remainder of the term of the employment agreement (as if no early termination had occurred). Payments Upon any Termination in connection with a Change in Control: Applicability. The change in control provisions applied if Mr. Konatich's employment was terminated (or a notice of termination is given) 90 days prior to or within 18 months after a change in control. Pursuant to the employment agreement, a change in control would have occurred (i) upon an acquisition of 35% of the voting power of economic interest of the Company's common stock, (ii) certain changes in the majority of the board of director's membership, (iii) the approval by the Company's stockholders of certain reorganizations, mergers or consolidations, (iv) the sale or other disposition of more than 50% of the Company's assets, (iv) a fundamental change in the business or (v) a hostile takeover. Change of Control Payment. If Mr. Konatich was terminated within the applicable period other than for death, disability, or by him without cause, the Company would have been required to pay to him, in a lump sum, on or prior to the 5th day following the date of termination, an amount equal to his salary and all other amounts due under his employment agreement for the remainder of its term, plus a gross up payment and any accrued and unpaid base salary. Stock Option Floor. Upon a change in control all stock options and other stock-based grants to Mr. Konatich by SIGA would have immediately vested and become exercisable as of such date. Gross Up Payment. If Mr. Konatich had incurred the excise tax imposed by the IRS on "Excess Parachute Payments" the Company would have been required to pay an additional amount such that the amount retained by Mr. Konatich after deduction of any excise tax on both the Excess Parachute Payment and any federal, state and local income tax (together with penalties and interest) as well as the excise tax due on the gross up itself would have been equal to the amounts he would have received upon a change of control had no such tax been imposed. Satisfactory Alternative. Mr. Konatich's rights with respect to a change in control termination would not have applied if, prior to or simultaneously with a such a termination due to a change in control, he was offered employment within the New York Metro area by another business as its chief financial officer at a level of compensation equal to or greater than his compensation by the Company. Pursuant to Mr. Konatich's current employment agreement (which was effective as of January 22, 2007), the following termination and change in control-related circumstances would trigger payments or the provision of other benefits: o Termination by the Company without cause or by Mr. Konatich for good reason. o Termination by the Company within 90 days of the occurrence of a change in control (other than for cause) o Termination by the Company for cause or by Mr. Konatich without good reason. o Termination by the Company based on Mr. Konatich's death or total disability. If Mr. Konatich's employment agreement is terminated without cause or if Mr. Konatich terminates his employment for good reason, he will be entitled to the following: (i) any accrued but unpaid salary for services rendered through the date of termination (ii) any vacation accrued to the date of termination, in accordance with Company policy; (iii) any accrued but unpaid expenses through the date of termination required to be reimbursed in accordance with his employment agreement; (iv) any benefits to which he may be entitled upon termination pursuant to the plans, programs and grants referred to in the employment agreement in accordance with the terms of such plans, programs and grants, (v) the continued payment of his salary for two (2) years; and (vi) the Company shall take all such action as is necessary such that all stock options and other stock-based grants to Mr. Konatich shall, immediately and irrevocably vest and become exercisable as of the date of termination and shall remain exercisable for a period of not less than one (1) year from the date of termination. If Mr. Konatich's employment agreement is terminated within 90 days after the occurrence of a change in control other than for cause, he will be entitled to the following: (i) any accrued but unpaid salary for services rendered through the date of termination (ii) any vacation accrued to the date of termination, in accordance with Company policy; (iii) any accrued but unpaid expenses through the date of termination required to be reimbursed in accordance with his employment 26 agreement; (iv) any benefits to which he may be entitled upon termination pursuant to the plans, programs and grants referred to in the employment agreement in accordance with the terms of such plans, programs and grants, (v) the continued payment of his salary for two (2) years; and (vi) the Company shall take all such action as is necessary such that all stock options and other stock-based grants to Mr. Konatich shall, immediately and irrevocably vest and become exercisable as of the date of termination and shall remain exercisable for a period of not less than one (1) year from the date of termination. If Mr. Konatich's employment is terminated for cause, or if he voluntarily terminates his employment, he will be entitled to the following: (i) any accrued but unpaid salary for services rendered through the date of termination (ii) any vacation accrued to the date of termination, in accordance with Company policy; (iii) any accrued but unpaid expenses through the date of termination required to be reimbursed in accordance with his employment agreement; and (iv) any benefits to which he may be entitled upon termination pursuant to the plans, programs and grants referred to in the employment agreement in accordance with the terms of such plans, programs and grants. If Mr. Konatich's employment is terminated prior to the expiration of the term by reason of death or total disability, his estate or beneficiaries will be entitled to the following: (i) any accrued but unpaid salary for services rendered through the date of termination (ii) any vacation accrued to the date of termination, in accordance with Company policy; (iii) any accrued but unpaid expenses through the date of termination required to be reimbursed in accordance with his employment agreement; and (iv) any benefits to which he may be entitled upon termination pursuant to the plans, programs and grants referred to in the employment agreement in accordance with the terms of such plans, programs and grants. Severance Arrangement for Dr. Hruby The following table and footnotes describe and quantify the potential payments upon termination or change in control for Dr. Hruby, assuming that termination or change-in-control was effective as of December 31, 2006: Termination by the Company without cause (or by the Termination upon Termination by the officer for good death or Company due to a Dr. Dennis E. Hruby cause) disability change in control Aggregate monthly cash payments $ 225,000 $ -- $ -- Lump sum cash payment -- -- 225,000 Value of accelerated stock options -- -- -- ------------ ------------ ------------ Total $ 225,000 $ -- $ 225,000 ============ ============ ============ Pursuant to Dr. Hruby's prior employment agreement (which was in effect as of December 31, 2006), the following termination and change in control-related circumstances would trigger payments or the provision of other benefits: o Termination by the Company for cause (including by providing one (1) year written notice with such termination being treated as a termination for cause). o Termination by the Company based on Dr. Hruby's death or disability. o Termination by the Company without cause (or by Dr. Hruby for good reason). o Termination by the Company due to a change in control. Payments Upon any Termination other than in connection with a Change in Control: If Dr. Hruby was terminated for cause or disability, or if he resigned for reasons other than a material breach by the Company of its obligations under his employment agreement, or a material reduction of his duties, or if he died, then the Company had no obligation to pay Dr. Hruby any amount, whether for salary, benefits, bonuses, or other compensation or expense reimbursements of any kind, accruing after his termination, and such rights would be, except as otherwise required by law, forfeited immediately upon termination. However, payments of base salary would continue until the expiration of the employment agreement where Dr. Hruby was terminated for death or disability. If the Company had terminated Dr. Hruby without cause, then the Company would have been obligated to continue to pay Dr. Hruby's salary and all other amounts due under the employment agreement for the remainder of the term of the employment agreement (as if no early termination had occurred). 27 Payments Upon any Termination in connection with a Change in Control: Applicability. The change in control provisions applied if Dr. Hruby's employment was terminated (or a notice of termination is given) 90 days prior to or within 12 months after a change in control. Pursuant to the employment agreement, a change in control would have occurred (i) upon an acquisition of 35% of the voting power of economic interest of the Company's common stock, (ii) certain changes in the majority of the board of director's membership, (iii) the approval by the Company's stockholders of certain reorganizations, mergers or consolidations, (iv) the sale or other disposition of more than 50% of the Company's assets, (iv) a fundamental change in the business or (v) a hostile takeover. Change of Control Payment. If Dr. Hruby was terminated within the applicable period other than for death, disability, or by him for any reason, the Company would have been required to pay to him, in a lump sum, on or prior to the 5th day following the date of termination, an amount equal to his salary and all other amounts due under his employment agreement for the remainder of its term, plus a gross up payment and any accrued and unpaid base salary. Stock Option Floor. Upon a change in control all stock options and other stock-based grants to Dr. Hruby by SIGA would have immediately vested and become exercisable as of such date. Gross Up Payment. If Dr. Hruby had incurred the excise tax imposed by the IRS on "Excess Parachute Payments" the Company would have been required to pay an additional amount such that the amount retained by Dr. Hruby after deduction of any excise tax on both the Excess Parachute Payment and any federal, state and local income tax (together with penalties and interest) as well as the excise tax due on the gross up itself would have been equal to the amounts he would have received upon a change of control had no such tax been imposed. Satisfactory Alternative. Dr. Hruby's rights with respect to a change in control termination would not have applied if, prior to or simultaneously with such a termination due to a change in control, he was offered employment within 50 miles of Albany Oregon by another business at a level of compensation equal to or greater than his compensation by SIGA Pursuant to Dr. Hruby's current employment agreement (which was effective as of January 22, 2007), the following termination and change in control-related circumstances would trigger payments or the provision of other benefits: o Termination by the Company without cause or by Dr. Hruby for good reason. o Termination by the Company within 90 days of the occurrence of a change in control (other than for cause) o Termination by the Company for cause or by Dr. Hruby without good reason. o Termination by the Company based on Dr. Hruby's death or total disability. If Dr. Hruby's employment agreement is terminated without cause or if Dr. Hruby terminates his employment for good reason, he will be entitled to the following: (i) any accrued but unpaid salary for services rendered through the date of termination (ii) any vacation accrued to the date of termination, in accordance with Company policy; (iii) any accrued but unpaid expenses through the date of termination required to be reimbursed in accordance with his employment agreement; (iv) any benefits to which he may be entitled upon termination pursuant to the plans, programs and grants referred to in the employment agreement in accordance with the terms of such plans, programs and grants, (v) the continued payment of his salary for two (2) years; and (vi) the Company shall take all such action as is necessary such that all stock options and other stock-based grants to Dr. Hruby shall, immediately and irrevocably vest and become exercisable as of the date of termination and shall remain exercisable for a period of not less than two (2) years from the date of termination. If Dr. Hruby's employment agreement is terminated within 90 days after the occurrence of a change in control other than for cause, he will be entitled to the following: (i) any accrued but unpaid salary for services rendered through the date of termination (ii) any vacation accrued to the date of termination, in accordance with Company policy; (iii) any accrued but unpaid expenses through the date of termination required to be reimbursed in accordance with his employment agreement; (iv) any benefits to which he may be entitled upon termination pursuant to the plans, programs and grants referred to in the employment agreement in accordance with the terms of such plans, programs and grants, (v) the continued payment of his salary for two (2) years; and (vi) the Company shall take all such action as is necessary such that all stock options and other stock-based grants to Dr. Hruby shall, immediately and irrevocably vest and become exercisable as of the date of termination and shall remain exercisable for a period of not less than two (2) years from the date of termination. If Dr. Hruby's employment is terminated for cause, or if he voluntarily terminates his employment, he will be entitled to the following: (i) any accrued but unpaid salary for services rendered through the date of termination (ii) any 28 vacation accrued to the date of termination, in accordance with Company policy; (iii) any accrued but unpaid expenses through the date of termination required to be reimbursed in accordance with his employment agreement; and (iv) any benefits to which he may be entitled upon termination pursuant to the plans, programs and grants referred to in the employment agreement in accordance with the terms of such plans, programs and grants. If Dr. Hruby's employment is terminated prior to the expiration of the term by reason of death or total disability, his estate or beneficiaries will be entitled to the following: (i) any accrued but unpaid salary for services rendered through the date of termination (ii) any vacation accrued to the date of termination, in accordance with Company policy; (iii) any accrued but unpaid expenses through the date of termination required to be reimbursed in accordance with his employment agreement; and (iv) any benefits to which he may be entitled upon termination pursuant to the plans, programs and grants referred to in the employment agreement in accordance with the terms of such plans, programs and grants.

In connection with such agreed upon resignation, SIGA and Dr. Kasten entered into a Separation Agreement dated March 31, 2006 (the "Separation Agreement"). Under the provisions of the Separation Agreement, Dr. Kasten received his salary on the existing terms and conditions as set forth in his employment agreement with SIGA, dated July 2, 2004 (the "Kasten Employment Agreement") in lieu of any other severance or payment, through September 16, 2006 (the "Separation Period"). Concurrently with the execution of the Separation Agreement, SIGA and Dr. Kasten also amended Dr. Kasten's Incentive Stock Option Agreement such that Dr. Kasten's "Milestone Options" (as such term is defined in the Kasten Employment Agreement) were cancelled and Dr. Kasten's "Time Vested Options" (as such term is defined in the Kasten Employment Agreement) were amended such that with respect to the Time Vested Options which had not vested as of the date of the Separation Agreement, such options vested as follows: with respect to 166,666 shares, as of July 2, 2006, and with respect to the remaining 83,334 shares, as of January 2, 2007. Time Vested Options granted to Dr. Kasten which vested prior to the date of the Separation Agreement shall remain unchanged. Dr. Kasten was permitted to continue to receive medical and/or dental insurance benefits under the relevant SIGA plans until (i) the end of the Remaining Tenure (defined as the earlier of April 30, 2006 or Dr. Kasten's obtaining new employment), (ii) he became entitled to Medicare or (iii) he became eligible for coverage under medical and/or dental insurance benefit plans, as the case may be, of another employer through his future employment, whichever occurred first. The Separation Agreement also contains mutual non-disparagement and release terms, requires that Dr. Kasten remain available to SIGA on a reasonable basis for transitional purposes during the Separation Period and requires SIGA to indemnify Dr. Kasten under the terms of its certificate of incorporation and bylaws for acts relating to his employment. Severance Arrangement for Dr. Rose Pursuant to Dr. Rose's current employment agreement (which was effective as of January 22, 2007), the following termination and change in control-related circumstances would trigger payments or the provision of other benefits: o Termination by the Company without cause or by Dr. Rose for good reason. o Termination by the Company within 90 days of the occurrence of a change in control (other than for cause) o Termination by the Company for cause or by Dr. Rose without good reason. o Termination by the Company based on Dr. Rose's death or total disability.

See "Annex A" to this proxy statement for the full "Statement of Policy with respect to Related Party Transactions." Under these procedures, at each calendar year's first regularly scheduled Audit Committee meeting, management recommends related party transactions be entered into by the Company for that calendar year, including the proposed aggregate value of such transactions, if applicable. After review, the Audit Committee either approves or disapproves such transactions, and at each subsequently scheduled meeting, management is required to update the Audit Committee as to any material change to those proposed transactions. Further, in the event management recommends any further related party transactions subsequent to the first calendar year meeting, such transactions may be presented to the Audit Committee for approval or preliminarily entered into by management subject to ratification by the Audit Committee; provided that, if ratification shall not be forthcoming, management shall make all reasonable efforts to cancel or annul such transactions. In addition, with respect to any related party transaction that includes a compensation component, management will submit the terms of such proposed compensation (or any subsequent material changes to such compensation) to the Compensation Committee for its review. After its review, the Compensation Committee either approves or disapproves the compensation component of the related party transaction and informs management and the Audit Committee of such approval or disapproval. TRANSACTIONS WITH RELATED PERSONS Based on information provided by the directors and the executive officers, the Audit Committee determined that there were no related person transactions to be reported in this proxy statement other than: During the year ended December 31, 2006, we were billed by an affiliate of TransTech Pharma, for services provided in connection with the manufacturing of our leading drug candidate, SIGA-246. Kramer Levin Naftalis and Frankel LLP, the Company's legal counsel billed the Company for legal services provided to the Company. 33 PROPOSAL NO. 2 RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Audit Committee of the Board of Directors has appointed the firm of PricewaterhouseCoopers LLP as SIGA's independent registered public accounting firm to audit the financial statements of SIGA for the fiscal year ending December 31, 2007, and recommends that stockholders vote for ratification of this appointment. 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 $235,000 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, 2006, reviews of the interim financial statements included in SIGA's Forms 10-Q filed during the year ended December 31, 2006 and consents and reviews of various documents filed with the SEC during the year ended December 31, 2006. PricewaterhouseCoopers LLP billed SIGA $184,300 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, 2005, reviews of the interim financial statements included in SIGA's Forms 10-Q filed during the year ended December 31, 2005 and consents and reviews of various documents filed with the SEC during the year ended December 31, 2005. Audit Related Fees PricewaterhouseCoopers LLP billed SIGA $183,236 in the aggregate, for audit related services rendered by them during the year ended December 31, 2006. There were no Audit Related Fees in 2005. 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, 2006 or December 31, 2005. 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, 2006 or December 31, 2005. 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 2005 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. 34 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, 2007. STOCKHOLDER PROPOSALS Stockholder proposals to be presented at the 2008 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 January 1, 2008. 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 2008 Annual Meeting of Stockholders, if SIGA is not provided notice of a stockholder proposal prior to March 1, 2008, 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, 2006, each of the following individuals failed to file on a timely basis one report relating to one transaction as required by Section 16 of the exchange Act: Dr. Rose, Mr. Antal, Mr. Constance, Mr. Drapkin, Dr. Hammer, Dr. Mjalli, Dr. Oz, Mr. Savas, Ms. Slotkin and Dr. Weiner. All reports were subsequently filed. AVAILABILITY OF ANNUAL REPORT AND FORM 10-K TO STOCKHOLDERS SIGA's Annual Report to Stockholders for the year ended December 31, 2006 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-K, 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 408, 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. If any other matters should come before the Annual Meeting, the persons named in the accompanying proxy will have discretionary authority to vote all proxies in accordance with their best judgment, unless otherwise restricted by law.

STATEMENT OF POLICIES AND PROCEDURES WITH RESPECT TO RELATED PARTY TRANSACTIONS I. Introduction The board of directors (the "Board of Directors") of SIGA Technologies, Inc. (the "Company") recognizes that related party transactions present a heightened risk of conflicts of interest and/or the perception of improper valuation. Therefore, the Board of Directors adopted this policy, which shall be followed in connection with all related party transactions involving the Company. A. Under this policy, any "Related Party Transaction" shall be consummated or shall continue only if: 1. the Audit Committee of the Board of Directors has approved or ratified such transaction in accordance with the guidelines set forth in the policy and if the transaction is on terms comparable to those that could be obtained in arm's length dealings with an unrelated third party; and 2. the transaction involves compensation, such that the terms of such compensation have been approved by the Compensation Committee of the Board of Directors. B. For these purposes, a "Related Party" is: 1. any director, nominee for director or executive officer of the Company; 2. any immediate family member of a director, nominee for director or executive officer of the Company (meaning any child, stepchild, parent, stepparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law or sister-in-law of such person, and any person (other than a tenant or employee) sharing the household of such person); 3. any person (or "group" as that term is used in Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the "Exchange Act")) who is the beneficial owner of more than 5% of the Company's voting securities; 4. any immediate family member of a person (or "group" as that term is used in Section 13(d)(3) of the Exchange Act) who is the beneficial owner of more than 5% of the Company's voting securities (meaning any child, stepchild, parent, stepparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law or sister-in-law of such person, and any person (other than a tenant or employee) sharing the household of such person); or 5. an entity that is owned or controlled by someone listed in 1, 2, 3 or 4 above, or an entity in which someone listed in 1, 2, 3 or 4 above has a substantial ownership interest or control of such entity. C. For these purposes, a "Related Party Transaction" is a transaction between the Company and any Related Party (including, without limitation, any transactions requiring disclosure under Item 404 of Regulation S-K under the Exchange Act), other than: 1. transactions available to all employees generally; or 2. transactions involving less than $5,000 when aggregated with all similar transactions. II. Committee Approval A. Audit Committee Approval. The Board of Directors has determined that the Audit Committee is best suited to review and approve Related Party Transactions. Accordingly, at each calendar year's first regularly scheduled Audit Committee meeting, management shall recommend Related Party Transactions be entered into by the Company for that calendar year, including the proposed aggregate value of such transactions, if applicable. After its review, the Audit Committee shall approve or disapprove such transactions and at each subsequently scheduled meeting, management shall update the Audit Committee as to any material change to those proposed transactions. In the event management recommends any further Related Party Transactions subsequent to the first calendar year meeting, such transactions may be presented to the Audit Committee for approval or preliminarily entered into by management subject to ratification by the Audit Committee; provided that, if ratification shall not be forthcoming, management shall make all reasonable efforts to cancel or annul such transactions. B. Compensation Committee Approval. The Board of Directors has determined that, if a Related Party Transaction involves compensation, it is advisable and appropriate for the Compensation Committee to review and approve of the compensation components of all Related Party Transactions. Accordingly, with respect to any Related Party Transaction that includes a compensation component, management will submit the terms of such proposed compensation (or any subsequent material changes to such compensation) to the Compensation Committee for its review. After its review, the Compensation Committee shall approve or disapprove the compensation component of the Related Party Transaction and inform management and the Audit Committee of such approval or disapproval. III. Disclosure The Securities Act of 1933, as amended, the Exchange Act, and the related rules and regulations promulgated thereunder require the disclosure of certain Related Party Transactions in the Company's filings with the Securities and Exchange Commission. All Related Party Transactions are to be disclosed to the extent required by law, rule or regulation in the Company's applicable filings. Furthermore, all Related Party Transactions shall be disclosed to the Audit Committee (and, to the extent they include a compensation component, to the Compensation Committee), and any material Related Party Transaction shall be disclosed to the full Board of Directors. IV. Other Agreements Management shall ensure that all Related Party Transactions are approved in accordance with any requirements of the Company's financing agreements (if any).
