PROXY STATEMENT
ANNUAL MEETING OF STOCKHOLDERS
MAY 14, 2008

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 14, 2008, 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 10, 2008.

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 2, 2008 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 33,955,215 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, 2008, 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:


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

•	by submitting another proxy with a later date; or

•	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, 2008; 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.

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.

THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE “FOR” THE ELECTION (ITEM 1 OF THE ENCLOSED PROXY CARD) OF DR. ROSE, MR. ANTAL, MR. CONSTANCE, MR. FASMAN, DR. HAMMER, DR. MJALLI, DR. OZ, MR. SAVAS, MS. SLOTKIN AND DR. WEINER AS DIRECTORS.

Meetings of the Board of Directors

The Board of Directors of SIGA held eight meetings during 2007. During 2007, no director attended fewer than 75% of the aggregate of the meetings of the Board of Directors and committees thereof, upon which such director served during the period for which he has been a director or committee member. In addition, one action was taken during 2007 by unanimous written consent of the Compensation Committee of the Board of 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 2007 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 2007. 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, if any, 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.”

Compensation Committee. The Compensation Committee, which currently consists of directors Steven L. Fasman, Paul G. Savas and Michael A. Weiner, held three meeting during 2007. On May 30, 2007, the Board of Directors elected Steven L. Fasman to replace retiring director Donald G. Drapkin on the Committee. 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 four meetings in 2007. 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 2007. 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 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:


•	The name and address, including telephone number, of the recommending stockholder;

•	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;

•	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;

•	Sufficient information about the proposed nominee for the Nominating Committee to make an informed decision regarding the qualifications of the proposed nominee;

•	Any relationship between the proposed nominee and the recommending stockholder; and

•	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.

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, free of charge, 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.

REPORT OF THE AUDIT COMMITTEE

The members of the Audit Committee have been appointed by the Board of Directors. During the 2007 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, 2007 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 2007 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, 2007. 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, 2008.

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 2007, was, an employee of SIGA.


	Respectfully submitted by the Audit Committee,
	Paul G. Savas, Chairman

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.

As a general matter, the compensation policy for officers and key employees includes:


	•	base salary, which is determined on an annual or semi-annual basis

	•	annual or other time-based cash incentive compensation, and

	•	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.

Thomas N. Konatich			Acting Chief Executive Officer (2) & Vice President, Chief Financial Officer, Secretary and Treasurer

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. Dr. Eric A. Rose, our Chief Executive Officer and Chairman of the Board, is 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. In 2007, the Compensation Committee retained the services of Mercer Consulting as its independent executive compensation consultant. In connection with this engagement, the Compensation Committee requested that Mercer Consulting review the fairness of the proposed compensation package for Dr. Eric A. Rose, who became the Company’s Chief Executive Officer on March 1, 2007.

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.

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 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 competitive position, scientific developments and improvements in relations with employees and investors.

For Dr. Rose, Mr. Konatich and Dr. Hruby, we paid as base salary in 2007 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.

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 of their current employment agreements. The annual incentive compensation earned by the other executives with respect to 2007 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.

For 2007, 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 $125,000.

Long-Term Incentive Awards

The Compensation Committee believes that granting stock options provides officers and key employees with a strong economic interest in maximizing stock price appreciation over the long term. The Committee also believes that the practice of granting stock options can be useful in retaining and recruiting the key talent necessary 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 reviews management’s recommendations concerning persons to be granted stock options, and determines the number 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, 2007 the Compensation Committee authorized awards of 200,000 options to Dr. Eric A. Rose, Chief Executive Officer (which vest pro rata on the first, second and third anniversaries of the date of grant).

During the year ended December 31, 2007, the Compensation Committee authorized awards of 150,000 options to Thomas N. Konatich, Chief Financial Officer, and 300,000 options to Dr. Dennis E. Hruby, Chief Scientific Officer. The Compensation Committee decided that of the awarded options to Mr. Konatich and Dr. Hruby, 50,000 options and 100,000 options, respectively, will vest pro rata on the first, second and third anniversaries of the date of grant. The Compensation Committee defined two groups of performance measures and decided that: (i) 50,000 options and 100,000 options, for Mr. Konatich and Dr. Hruby, respectively, will vest when the Company and one or more purchasers have entered into one or more contracts for the sale of the Company’s smallpox drug, ST-246, with an aggregate price of no less than $50 million; and the Company received at least an aggregate of $25 million in non-refundable payments pursuant to such contracts; and (ii) 50,000 options and 100,000 options, for Mr. Konatich and Dr. Hruby, respectively, will vest upon the acceptance of a New Drug Application for the Company’s smallpox drug, ST-246. All of the aforementioned options have an exercise price of $3.10 per share.

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 careers 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.

Our Compensation Policies

Section 162(m) Policy

The Compensation Committee has found it unnecessary to consider the applicability of Section 162(m) of the Code because no executive officer receives compensation in excess of one million dollars.

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 option awards to our executive officers and key employees when appropriate. 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.

Financial Restatement

Although we have not adopted a formal written policy, it is our Board of Directors’ informal policy that the Compensation Committee will, to the extent permitted by governing law, have the sole and absolute authority and discretion in consultation with the Board of Directors, to make retroactive adjustments to any cash or equity based incentive payments to executive officers where the payment was based upon the achievement of certain financial results that were subsequently the subject of a restatement, without regard to misconduct being involved. If the Compensation Committee chose to exercise this discretion, we would seek to recover any amount determined to have been improperly paid to the executive officer.

Option Awards

Our 1996 Incentive and Non-Qualified Stock Option Plan was adopted in 1996 and amended in 2001, 2004 and 2005. The maximum number of shares of common stock available for issuance under the Plan is 11,000,000. Stock options may be granted to key employees, consultants and outside directors pursuant to the Plan.

The Plan is administered by our Compensation Committee, which reviews management’s recommendations concerning persons to be granted stock options, and determines the number 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 Steven L. Fasman, who serves as Chair, Paul G. Savas and Michael A. Weiner, M.D. See “Committees of the Board of Directors” above for more information.

Directors who are not currently receiving compensation as officers or employees of the Company or any of its affiliates 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. The chairman of each of the Audit Committee, Nominating and Corporate Governance Committee, and the Compensation Committee will each receive $1,000 per meeting for meetings of

the Audit Committee, Nominating and Corporate Governance and Compensation Committee, respectively. All other members of the respective committees will receive $500 per meeting for meetings of the committees.

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. 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.

TRANSACTIONS WITH RELATED PERSONS

REVIEW, APPROVAL OR RATIFICATION OF TRANSACTIONS WITH RELATED PERSONS

The Company’s policies and procedures for reviewing, approving, and ratifying transactions with related persons are set forth in a written policy. 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, 2007, we were billed by TransTech Pharma, Inc. and its affiliate for services provided in connection with our lead development programs.

Kramer Levin Naftalis and Frankel LLP, the Company’s legal counsel, billed the Company for legal services provided to the Company.

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, 2008, 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 $348,000 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, 2007, reviews of the interim financial statements included in SIGA’s Forms 10-Q filed during the year ended December 31, 2007 and consents and reviews of various documents filed with the SEC during the year ended December 31, 2007.

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.

Audit Related Fees

There were no Audit Related Fees in 2007.

PricewaterhouseCoopers LLP billed SIGA $183,236 in the aggregate, for audit related services rendered by them during the year ended December 31, 2006.

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, 2007 or December 31, 2006.

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, 2007 or December 31, 2006.

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 2007 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, 2008.

STOCKHOLDER PROPOSALS

Stockholder proposals to be presented at the 2009 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, 2009. 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 2009 Annual Meeting of Stockholders, if SIGA is not provided notice of a stockholder proposal prior to March 1, 2009, 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, 2007, no director failed to file on a timely basis a report relating to a transaction as required by Section 16 of the exchange Act.

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.
