Notes to the September 30, 2002 Financial Statements 1. Basis of Presentation The financial statements of SIGA Technologies, Inc. (the "Company") have been prepared in accordance with generally accepted accounting principles for interim financial information and the rules of the Securities and Exchange Commission (the "SEC") for quarterly reports on forms 10-QSB and do not include all of the information and footnote disclosures required by generally accepted accounting principles for complete financial statements. These statements should be read in conjunction with the Company's audited financial statements and notes thereto for the year ended December 31, 2001, included in the 2001 Form 10-KSB. In the opinion of management, the accompanying unaudited financial statements include all adjustments, consisting of normal adjustments, necessary for a fair presentation of the results of operations for the interim periods. The results of operations for the three and nine months ended September 30, 2002 are not necessarily indicative of the results of operations to be expected for the full year ending December 31, 2002. The accompanying financial statements have been prepared assuming that the company will continue as a going concern. Management believes that current resources will be sufficient to support its planned operations through the end of September 30, 2003. The Company does not have commercial biomedical products, and does not expect to have such for several years, if at all. The Company believes that it will need additional funds to complete the development of its biomedical products. If additional financing can not be obtained, long-term operations will need to be scaled back or discontinued. 2. Private Financing On September 27, 2002 the Company completed a private financing and issued 1,037,500 shares of its common stock and warrants to acquire 518,750 shares of common stock for $2.25 per share, exercisable for a period of five years. The Company received net proceeds of $931,220 on October 4, 2002. 3. License and Research Support Agreement In May, 2002, the Company was awarded a Phase II Small Business Innovation Research (SBIR) grants from the National Institutes for Health in the amount $865,000. The grant is for a three-year period, and will support the Company's antibiotic and vaccine development programs. The Company recognized approximately $88,800 of related revenue during the quarter ended September 30, 2002. 4. New Accounting Pronouncements In July 2002, SFAS 146, Accounting for Costs Associates with Exit or Disposal Activities, was issued. SFAS 146 addresses the recognition, measurement and reporting of costs associated with exit or disposal activities, that are currently accounted for pursuant to EITF Issue No. 94-3, Liabilities Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity. Under SFAS No. 146, such liabilities, with the exception of certain one-time termination benefits, will be recognized and measured initially at their fair value in the period in which the liability is incurred. SFAS No. 146 is effective for the fiscal years beginning after December 31, 2002. 4

Management's Discussion and Analysis of Financial Condition and Result of Operations The following discussion should be read in conjunction with our financial statements and notes to those statements and other financial information appearing elsewhere in this Quarterly Report. In addition to historical information, the following discussion and other parts of this Quarterly Report contain forward-looking information that involves risks and uncertainties. Overview We are a development stage technology company, whose primary focus is in biopharmaceutical product development. Since our inception in December 1995, our efforts have been principally devoted to research and development, securing patent protection, obtaining corporate relationships and raising capital. Since inception through September 30, 2002, we have sustained cumulative net losses of $28,464,496 including non-cash charges in the amount of $1,457,458 for the write-off of research and development expenses associated with the acquisition of certain technology rights acquired from a third party in exchange for our common stock. Also included in the cumulative loss to date, are non-cash charges of $2,949,420 incurred for stock option and warrant compensation expense. Our losses have resulted primarily from expenditures incurred in connection with research and development, patent preparation and prosecution and general and administrative expenses. From inception through September 30, 2002, research and development expenses amounted to $13,203,528, patent preparation and prosecution expenses totaled $1,427,087, general and administration expenses amounted to $16,665,485. From inception through September 30, 2002 revenues from research and development agreements and government grants totaled $3,516,238. Since inception, SIGA has had limited resources, has incurred cumulative net operating losses of $27,779,862 and expects to incur additional losses to perform further research and development activities. We do not have any biomedical products which are commercially available, and we do not expect to have such products for several years, if at all. We believe that we will need additional funds to complete the development of our biomedical products. Our plans with regard to these matters include continued development of our products as well as seeking additional research support funds and financial arrangements. Although we continue to pursue these plans, there is no assurance that we will be successful in obtaining sufficient financing on terms acceptable to us. The financial statements do not include any adjustments that might result from the outcome of this uncertainty. Management believes it has sufficient funds to support operations through the third quarter of 2003. In the event that we are unable to raise additional capital at that time, future operations will need to be scaled back or discontinued. Our biotechnology operations are run out of our research facility in Corvallis, Oregon. We continue to seek to fund a major portion of our ongoing vaccine and antibiotic programs through a combination of government grants and strategic alliances. While we have had success in obtaining strategic alliances and grants, no assurance can be given that we will continue to be successful in obtaining funds from these sources. Until additional relationships are established, we expect to continue to incur significant research and development costs and costs associated with the development of product for use in clinical trials and pre-clinical testing. It is expected that general and administrative costs, including patent and regulatory costs, necessary to support clinical trials and research and development will continue to be significant in the future. To date, we have not marketed, or generated revenues from the commercial sale of any products. Our biopharmaceutical product candidates are not expected to be commercially available for several years, if at all. Accordingly, we expect to incur operating losses for the foreseeable future. There can be no assurance that we will ever achieve profitable operations. In March of 2002, we signed a non-binding letter of intent to acquire all of the outstanding shares of Allergy Therapeutics (Holdings) Limited in a stock-for-stock transaction. In July of 2003 we announced the termination of the letter of intent to acquire all the shares of Holdings due to the unfavorable market conditions that existed at the time of the termination. We incurred approximately $550,000 of expenses in connection with this contemplated transaction, some of which were still outstanding as of September 30, 2002. 5

Results of Operations Three Months ended September 30, 2002 and September 30, 2001. Revenue for the three months ended September 30, 2002 was $89,738 an approximate 43% decline from the $157,500 revenue recognized for the three months ended September 30, 2001. Revenue for the three months ended September 30, 2001 included the final payment of $112,500 from Wyeth-Ayerst under our R&D agreement with Wyeth-Ayerst. Revenue for the three months ended September 30, 2002 included $88,838 from the Small Business Innovation Research (SBIR) grant from the National Institutes of Health (NIH) which we received in May of 2002. This grant is for a total of approximately $865,000 to support research over a two-year period. Of the total grant, approximately $521,000 has been allotted for work to be performed in the first twelve months of the grant. General and administrative expense for the three months ended September 30, 2002 was $273,280, a decrease of approximately 78% from the $1,259,109 expense incurred for the three months ended September 30, 2001. Expenses for the three months ended September 30, 2001 included a non-cash charge of $612,750 to reflect granting of options to directors with an exercise price that was less than the fair market value of our shares at the time the award was approved by stockholders. Excluding this non-cash charge, general and administrative expense for the three months ended September 30, 2002 declined by approximately 57%. This decrease was primarily the result of lower payroll, rent, legal and accounting expenses. Research and development expenses decreased 14.8% to $423,850 for the three months ended September 30, 2002 from $497,739 for the three months ended September 30, 2001. The reduction is primarily the result of a decrease in sponsored research and lower spending for laboratory supplies. Patent preparation expense of $26,918 for the three months ended September 30, 2002 was approximately 344% higher than the credit of $11,046 recognized for the three months ended September 30, 2001. The credit recognized for the three months ended September 30, 2001 was the result of patent expenses that were made in periods prior to the September 30, 2001 that were to be reimbursed by Wyeth-Ayerst and Washington University. The three months ended September 30, 2002 reflect only reimbursement of expenses incurred in that period. Net interest income was $4,672 for the three months ended September 30, 2002 compared to net interest expense of $2,220 for the three months ended September 30, 2001. The improvement in net interest was the result of the conversion of the remainder of the $1,500,000 principle amount of the 6% convertible debenture and accrued interest into equity in the second half of 2001. Net loss for the three months September 30, 2002 was $629,638, an approximate 60% decrease from the $1,590,521 loss for the three months ended September 30, 2001. The decrease in the net loss was the primarily the result of substantially lower general and administration expense as discussed above. Nine Months ended September 30, 2002 and September 30, 2001. Revenue for the nine months ended September 30, 2002 was $229,057 compared to $1,144,500 for the nine months ended September 30, 2001, an approximate 80% decrease. Revenue for the nine-month period of the prior year included recognition of $562,500 from payments made by Wyeth-Ayerst that had been made to fund research in prior periods and were recorded as deferred revenue pending signing an extension of our research agreement with Wyeth. In total we recognized $912,500 in research and milestone payments from Wyeth-Ayerst for the nine months ended September 30, 2001. No payments were made in the nine-month period ended September 30, 2002. Revenue in the current year nine-month period include $149,057 from a Phase II SBIR grant from the NIH and $75,000 from a subcontract with Oregon State University. General and administrative expense for the nine months ended September 30, 2002 was $1,282,040, a decrease of approximately 35% from the $1,959,708 incurred for the nine months ended September 30, 2001. The nine months ended September 30, 2001 included a non-cash charge of $612,750 to reflect the granting of options to directors with an exercise price less than the fair market value of our shares at the time the option plan was approved by stockholders. In addition, lower payroll costs in the current year nine-month period offset increased legal and accounting costs associated with the terminated "letter of intent" to acquire Allergy Therapeutics Holdings, Ltd. 6

Research and development expenses decreased approximately 12% to $1,194,453 for the nine months ended September 30, 2002 from $1,357,286 for the nine months ended September 30, 2001. The decline in expenses was the result of lower expenses for payroll, laboratory supplies and sponsored research. Patent preparation expense for the nine months ended September 30, 2002 was $72,332 compared to $69,891 for the nine months ended September 30, 2001, an increase of 3.5%. Patent activities, as well as the reimbursement of certain patent expenses by Wyeth-Ayerst and Washington University was essentially the same in both nine-month periods. Net interest income was $26,447 for the nine months ended September 30, 2002 compared to net interest expense of $235,985 for the nine months ended September 30, 2001. The improvement in net interest was the result of the conversion of the remainder of the $1,500,000 principle amount of the 6% convertible debenture and accrued interest into equity in the second half of 2001. Net loss for the nine months ended September 30, 2002 was $2,293,321, compared to a loss of $2,478,372 for the nine months ended September 30, 2001. The approximate 8% decrease from the prior year period was largely the result reduced general and administration expenses and reduced interest expense offsetting reduced levels of revenue as presented in detail above. Liquidity and Capital Resources As of September 30, 2002 we had $1,083,208 in cash and cash equivalents and a subscription receivable of $931,250 representing net proceeds from a subscription to purchase units which were comprised of our common stock and warrants to purchase stock. In March of 2002, we signed a non-binding letter of intent to acquire all the outstanding shares of Allergy Therapeutics (Holdings) Limited in a stock-for-stock transaction. In July of 2002 the letter of intent was terminated due to changes in market conditions. We incurred approximately $550,000 of expenses in connection with this contemplated transaction, some of which were still outstanding as of September 30, 2002. In May of 2002, we received a Small Business Innovation Research (SBIR) grant from the National Institutes of Health (NIH). The grant is for a total of approximately $865,000 to support research over a two-year period. Of the total grant, approximately $521,000 has been allotted for work to be performed in the first twelve months of the grant. During the nine months ended September 30, 2002, we recorded revenue in the amount of $149,057 relating to the grant. As discussed above, in September 2002, we received subscriptions from a private placement of units consisting of 1,037,500 shares of our common stock and warrants to purchase 518,750 shares of common stock at an exercise price of $2.25 per share to a group of private investors. In October 2002, we received the net proceeds of $931,250 from the placement. We anticipate that our current resources and the funding available through the SBIR grant will be sufficient to finance our currently anticipated needs for operating and capital expenditures through the third quarter of 2003. In addition, we will attempt to generate additional working capital through a combination of collaborative agreements, strategic acquisitions, strategic alliances, research grants, equity and debt financing. However, no assurance can be provided that additional capital will be obtained through these sources or, if obtained, will be on commercially reasonable terms. In the event we are unable to raise additional capital, operations will need to be scaled back or discontinued. Our working capital and capital requirements will depend upon numerous factors, including pharmaceutical research and development programs; pre-clinical and clinical testing; timing and cost of obtaining regulatory approvals; levels of resources that we devote to the development of manufacturing and marketing capabilities; technological advances; status of competitors; and our ability to establish collaborative arrangements with other organizations. 7
