Introduction SIGA Technologies, Inc. is referred to throughout this report as "SIGA," "the Company," "we" or "us." SIGA is a biotechnology company incorporated in Delaware on December 9, 1996. We aim to discover, develop and commercialize novel anti-infectives, antibiotics and vaccines for serious infectious diseases, including products for use in defense against biological warfare agents such as Smallpox and Arenaviruses (hemorrhagic fevers). Our anti-viral programs are designed to prevent or limit the replication of the viral pathogen. Our anti-infectives programs are aimed at the increasingly serious problem of drug resistance. These programs are designed to block the ability of bacteria to attach to human tissue, the first step in the infection process. We are also developing a technology for the mucosal delivery of our vaccines which may allow the vaccines to activate the immune system at the mucus lined surfaces of the body -- the mouth, the nose, the lungs and the gastrointestinal and urogenital tracts -- the sites of entry for most infectious agents. Product Candidates and Market Potential SIGA Biological Warfare Defense Product Portfolio Anti-Smallpox Drug: While deliberate introduction of any pathogenic agent would be devastating, we believe the one that holds the greatest potential for harming the general U.S. population is Smallpox. At present there is no effective drug with which to treat or prevent Smallpox infections. To address this serious risk, SIGA scientists have identified a lead drug candidate, SIGA-246, which inhibits vaccinia, cowpox, ectromelia (mousepox), monkeypox, camelpox, and variola replication in cell culture but not other unrelated viruses. Given the safety concerns with the current smallpox vaccine, there should be several uses for an effective smallpox antiviral drug: prophylactically, to protect the non-immune who are at risk to exposure; therapeutically, to prevent disease or death in those exposed to smallpox; and lastly, as an adjunct treatment to the immunocompromised. SIGA scientists are also working on several other smallpox drug targets, including the viral proteinases, to develop additional drug candidates for use in combination therapy if necessary. Anti-Arenavirus Drug: Arenaviruses are hemorrhagic fever viruses that have been classified as Category A agents by the Centers for Disease Control and Prevention (CDC) due to the great risk that they pose to public health and national safety. Among the Category A viruses recognized by the Centers for Disease Control and Prevention, there are four hemorrhagic fever arenaviruses (Junin, Machupo, Guanarito and Sabia viruses) for which there are no United States Food and Drug Administration (FDA) approved treatments available. In order to meet this threat, SIGA scientists have identified a lead drug candidate, ST-294, which has demonstrated significant antiviral activity in cell culture assays against arenavirus pathogens. SIGA also has earlier stage programs against other hemorrhagic fever viruses including Lassa virus, Lymphocytic choriomeningitis virus (LCMV), and Ebola in development. We 2 believe that the availability of arenavirus antiviral drugs will address national and global security needs by acting as a significant deterrent and defense against the use of arenaviruses as weapons of bioterrorism. Bacterial Commensal Vectors: Our scientists have developed methods that allow essentially any gene sequence to be expressed in Generally Regarded As Safe (GRAS) gram-positive bacteria, with the foreign protein being displayed on the surface of the live recombinant organisms. Since these organisms are inexpensive to grow and are very stable, this technology affords the possibility of rapidly producing live recombinant vaccines against any variety of biological agents that might be encountered, such as Bacillus anthracis (anthrax) or Smallpox. SIGA scientists are working to develop an alternative vaccine with improved safety for use in preventing human disease caused by pathogenic orthopoxviruses such as variola virus. To accomplish this goal we are utilizing our newly-developed BCV (bacterial commensal vector) technology. BCV utilizes gram-positive commensal bacteria, such as Streptococcus gordonii, to express heterologous antigens of interest, either in secreted form or attached to its external surface. Phase I human clinical trials indicate that this S. gordonii strain is safe and well-tolerated in humans. In several different animal model systems S. gordonii has been shown to efficiently express various antigens and elicit protective immune responses (cellular, humoral and mucosal). We believe that the delivery of selected vaccinia virus antigens via this live bacterial vector system will provide an effective and safe method for prevention of smallpox in humans. Surface Protein Expression (SPEX) System: Our scientists have harnessed the protein expression pathways of gram-positive bacteria and turned them into protein productions factories. Using our proprietary SPEX system, we can produce foreign proteins at high levels in the laboratory for use in subunit vaccine formulations. Furthermore, we can envision engineering these bacteria to colonize the mucosal surfaces of soldiers and/or civilians and secrete anti-toxins that protect against aerosolized botulism toxin. Antibiotics: To combat the problems associated with emerging antibiotic resistance, our scientists are developing drugs designed to hit a new target - the bacterial adhesion organelles. Specifically, by using novel enzymes required for the transport and/or assembly of the proteins and structures that bacteria require for adhesion or colonization, we are developing new classes of broad spectrum antibiotics. This may prove invaluable in providing prompt treatment to individuals encountering an unknown bacterial pathogen in the air or food supply. Market for Biological Defense Programs. The U.S. government's proposed budget for the Department of Homeland Security (the "DHS") for the fiscal year beginning October 1, 2005 includes $2.5 billion of federal spending on Project BioShield. In addition to contributing funds to the DHS, the Department of Defense will be looking for innovative approaches to the prevention and treatment of biological warfare agents. One of the major concerns is Smallpox -- although declared extinct in 1980 by the World Health Organization, there is a threat that a rogue nation or a terrorist group may have an illegal inventory of the virus that causes Smallpox. The only legal inventories of the virus are held under extremely tight security at the Centers for Disease Control and Prevention (the "Centers for Disease Control") in Atlanta, Georgia and at a laboratory in Russia. As a result of this threat, the U.S. government has announced its intent to make significant expenditures on finding a way to counteract the virus if turned loose by terrorists or on a battlefield. The Congressional Budget Office (the "CBO") reported that the DHS projects the acquisition of 60 million doses of new Smallpox vaccines over a three year period, commencing in 2005. At an estimated $15 per dose, the cost would be approximately $900 million. Further the CBO reports that the DHS will spend an additional $1 billion to replace expired stocks in 2007-2013. The FDA has amended its regulations, effective June 30, 2002, so that certain new drug and biological products used to reduce or prevent the toxicity of chemical, biological, radiological, or nuclear substances may be approved for use in humans based on evidence of effectiveness derived only from appropriate animal studies and any additional supporting data. We believe that this change could make it possible for us to have potential products in animal models approved for sale within a relatively short time frame if our programs are successful. Our Chief Scientific Officer, Dennis Hruby, has over 20 years experience working on Smallpox-related research and has been leading a SIGA/Oregon State University consortium working on an antiviral drug development project for the past two years. 3 The market potential for our biological warfare defense products has not been quantified as yet beyond the potential to obtain a share of the approximately $9 billion the federal government is committing to support research in the coming year. The government's purchase of approximately $800 million worth of an older version Smallpox vaccines to have an inventory on hand if needed is evidence of such market potential. SIGA Anti-Infectives Product Portfolio Our anti-infectives program is targeted principally toward drug-resistant bacteria and hospital-acquired infections. According to estimates from the Centers for Disease Control, approximately two million hospital-acquired infections occur each year in the United States. Our anti-infectives approaches aim to block the ability of bacteria to attach to and colonize human tissue, thereby blocking infection at the first stage in the infection process. By comparison, antibiotics available today act by interfering with either the structure or the metabolism of a bacterial cell, affecting its ability to survive and to reproduce. No currently available antibiotics target the attachment of a bacterium to its target tissue. We believe that, by preventing attachment, the bacteria should be readily cleared by the body's immune system. Gram-Positive Antibiotic Technology: One of our key anti-infective programs is based on a novel target for antibiotic therapy. Our scientists have identified an enzyme, a selective protease, used by most Gram-positive bacteria to anchor certain proteins to the bacterial cell wall. These surface proteins are the means by which certain bacteria recognize, adhere to and colonize specific tissue. Our strategy is to develop protease inhibitors as novel antibiotics. We believe protease inhibitors will have wide applicability to Gram-positive bacteria in general, including antibiotic resistant staphylococcus and a broad range of serious infectious diseases including meningitis and respiratory tract infections. In 1997, we entered into a collaborative research and license agreement with Wyeth to identify and develop protease inhibitors as novel antibiotics. In the first quarter of 2001, we received a milestone payment from Wyeth for delivery of the first quantities of protease for screening, and high-throughput screening for protease inhibitors was initiated. In connection with our effort on this program we have entered into a license agreement with the University of California at Los Angeles for certain technology that may be incorporated into our development of products for Wyeth. High throughput screening of compound libraries has been completed and lead compounds are currently being evaluated in the laboratory and in animals. Gram-Negative Antibiotic Technology: In 1998, we entered into a set of technology transfer and related agreements with MedImmune, Inc., Astra AB and Washington University, pursuant to which we acquired rights to certain Gram-negative antibiotic targets, products, screens and services developed at Washington University. In February 2000, we ended our collaborative research and development relationship with Washington University on this technology. (See "Collaborative Research and Licenses"). We maintain a non-exclusive license to technology acquired through these related agreements. We are using this technology in the development of antibiotics against Gram-negative pathogens. As described above, these bacteria use structures called pili to adhere to target tissue, and we plan to exploit the assembly and export of these essential infective structures as novel anti-infective targets. We continue to work on enhancing the intellectual property that we jointly share with Washington University. Broad-Spectrum Antibiotic Technology: An initial host response to pathogen invasion is the release of oxygen radicals, such as superoxide anions and hydrogen peroxide. The DegP protease is a first-line defense against these toxic compounds, which are lethal to invading pathogens, and is a demonstrated virulence factor for several important Gram-negative pathogens: Salmonella typhimurium, Salmonella typhi, Brucella melitensis and Yersinia enterocolitica. In all of these pathogens it was demonstrated that organisms lacking a functional DegP protease were compromised for virulence and showed an increased sensitivity to oxidative stress. It was also recently demonstrated that in Pseudomonas aeruginosa conversion to mucoidy, the so-called CF phenotype involves two DegP homologues. Our scientists recently demonstrated that the DegP protease is conserved in Gram-positive pathogens, including S. pyogenes, S. pneumoniae, S. mutans and S. aureus. Moreover, our investigators have shown a conservation of function of this important protease in Gram-positive pathogens and we believe that DegP represents a true broad-spectrum anti-infective development target. Our research has uncovered a virulence-associated target of the DegP protease that will be used to design an assay for high-throughput screening for the identification of lead inhibitors of this potentially important anti-infective target. 4 Market for Anti-infective Programs. There are currently more than 100 million prescriptions written for antibiotics annually in the U.S. and we estimate the worldwide market for antibiotics to be more than $26 billion. Although our products are too early in development to make accurate assessments of how well they might compete, if successfully developed and marketed against other products currently existing or in development at this time, the successful capture of even a relatively small global market share could lead to a large dollar volume of sales. Technology Anti-Infectives Technology: Prevention of Attachment and Infectivity The bacterial infectious process generally includes three steps: colonization, invasion and disease. The adherence of bacteria to a host's surface is crucial to establishing colonization. Bacteria adhere through a number of mechanisms, but generally by using highly specialized surface structures which, in turn, bind to specific structures or molecules on the host's cells or, as discussed below, to inanimate objects residing in the host. Once adhered, many bacteria will invade the host's cells and either establish residence or continue invasion into deeper tissues. During any of these stages, the invading bacteria can cause the outward manifestations of disease, in some cases through the production and release of toxin molecules. The severity of disease, while dependent on a large combination of factors, is often the result of the ability of the bacteria to persist in the host. These bacteria accomplish this persistence by using surface molecules which can alter the host's nonspecific mechanisms or its highly specific immune responses to clear or destroy the organisms. Unlike conventional antibiotics, our anti-infectives approaches aim to block the ability of pathogenic bacteria to attach to and colonize human tissue, thereby preventing infection at its earliest stage. Our scientific strategy is to inhibit the expression of bacterial surface proteins required for bacterial infectivity. We believe that this approach has promise in the areas of hospital-acquired drug-resistant infections and a broad range of other diseases caused by bacteria. Many special surface proteins used by bacteria to infect the host are anchored in the bacterial cell wall. Scientists at The Rockefeller University ("Rockefeller") have identified an amino acid sequence and related enzyme, a selective protease, that are essential for anchoring proteins to the surface of most Gram-positive bacteria. Published information indicates that this amino acid sequence is shared by more than 50 different surface proteins found on a variety of Gram-positive bacteria. This commonality suggests that this protease represents a promising target for the development of a new class of antibiotic products for the treatment of a wide range of infectious diseases. Experiments by our scientists have shown that without this sequence, proteins cannot become anchored to the bacterial surface and thus the bacteria are no longer capable of attachment, colonization or infection. Such "disarmed" bacteria should be readily cleared by the body's immune system. Our drug discovery strategy is to use a combination of structure-based drug design and high throughput screening procedures to identify compounds that inhibit the protease, thereby blocking the anchoring process. If successful, this strategy should provide relief from many Gram-positive bacterial infections, but may prove particularly important in combating diseases caused by the emerging antibiotic resistance of the Gram-positive organisms Streptococcu, aureus, Streptococcus pneumoniae, and the enterococci. In contrast to the above program, which focuses on Gram-positive bacteria, our pilicide program, based upon initial research performed at Washington University in St. Louis ("Washington University"), focuses on a number of new and novel targets all of which impact on the ability of Gram-negative bacteria to assemble adhesive pili on their surfaces. Pili are proteins on the surfaces of Gram-negative bacteria -- such as E. coli, salmonella, and shigella -- that are required for the attachment of the bacteria to human tissue, the first step in the infection process. This research program is based upon the well-characterized interaction between a periplasmic protein -- a chaperone -- and the protein subunits required to form pili. In addition to describing the process by which chaperones and pili subunits interact, we have developed an assay systems necessary to screen for potential therapeutic compounds, and have provided an initial basis for selecting novel antibiotics that work by interfering with the pili adhesion mechanism. 5 Vaccine Technologies: Mucosal Immunity and Vaccine Delivery Using proprietary technology licensed from Rockefeller, SIGA is developing specific commensal bacteria ("commensals") as a means to deliver mucosal vaccines. Commensals are harmless bacteria that naturally occupy the body's surfaces with different commensals inhabiting different surfaces, particularly the mucosal surfaces. Our vaccine candidates use genetically engineered commensals to deliver antigens for a variety of pathogens to the mucosal immune system. When administered, the genetically engineered commensals colonize the mucosal surface and replicate. By activating a local mucosal immune response, our vaccine candidates are designed to prevent infection and disease at the earliest possible stage, as opposed to most conventional vaccines which are designed to act after infection has already occurred. Our commensal vaccine candidates use Gram-positive bacteria. Rockefeller scientists have identified a protein region that is used by Gram-positive bacteria to anchor proteins to their surfaces. We are using the proprietary technology licensed from Rockefeller to combine antigens from a wide range of infectious organisms, both viral and bacterial, with the surface protein anchor region of a variety of commensal organisms. By combining a specific antigen with a specific commensal, vaccines may be tailored to both the target pathogen and its mucosal point of entry. To target an immune response to a particular mucosal surface, a commensal vaccine would employ a commensal organism that naturally inhabits that surface. For example, vaccines targeting sexually transmitted diseases might employ Lactobacillus acidophilus, a commensal colonizing the female urogenital tract. Vaccines targeting gastrointestinal diseases could employ Lactobacillus casei, a commensal colonizing the gastrointestinal tract. We have conducted initial experiments using Streptococcus gordonii ("S. gordonii"), a commensal that colonizes the oral cavity and which may be used in vaccines targeting pathogens that enter through the upper respiratory tract, such as the influenza virus. By using an antigen unique to a given pathogen, the technology may potentially be applied to any infectious agent that enters the body through a mucosal surface. Our scientists have expressed and anchored a variety of viral and bacterial antigens on the outside of S. gordonii, including the M6 protein from group A streptococcus, a group of organisms that causes a range of diseases, including strep throat, necrotizing fasciitis, impetigo and scarlet fever. In addition, proteins from other infectious agents, such as HIV and human papilloma virus have also been expressed using this system. We believe this technology will enable the expression of most antigens regardless of size or shape. In animal studies, we have shown that the administration of a genetically engineered S. gordonii vaccine prototype induces both a local mucosal immune response and a systemic immune response. We believe that mucosal vaccines developed using our proprietary commensal delivery technology could provide a number of advantages, including: o More complete protection than conventional vaccines: Mucosal vaccines in general may be more effective than conventional parenteral vaccines, due to mucosal vaccines' ability to produce both a systemic and local (mucosal) immune response. o Safety advantage over other live vectors: A number of bacterial pathogens have been genetically rendered less infectious, or attenuated, for use as live vaccine vectors. Commensals, by virtue of their substantially harmless nature, may offer a safer delivery vehicle without fear of genetic reversion to the infectious state inherent in attenuated pathogens. o Non-injection administration: Oral, nasal, rectal or vaginal administration of the vaccine eliminates the need for painful injections with their potential adverse reactions. o Potential for combined vaccine delivery: The Children's Vaccine Initiative, a worldwide effort to improve vaccination of children sponsored by the World Health Organization (WHO), has called for the development of combined vaccines, specifically to reduce the number of needle sticks per child, by combining several vaccines into one injection, thereby increasing compliance and decreasing disease. We believe our commensal delivery technology can be an effective method of delivery of multi-component 6 vaccines within a single commensal organism that address multiple diseases or diseases caused by multiple strains of an infectious agent. o Eliminating need for refrigeration: One of the problems confronting the effective delivery of parenteral vaccines is the need for refrigeration at all stages prior to injection. The stability of the commensal organisms in a freeze-dried state would, for the most part, eliminate the need for special climate conditions, a critical consideration, especially for the delivery of vaccines in developing countries. o Low cost production: By using a live bacterial vector, extensive downstream processing is eliminated, leading to considerable cost savings in the production of the vaccine. The potential for eliminating the need for refrigeration would add considerably to these savings by reducing the costs inherent in refrigeration for vaccine delivery. Strep Throat Vaccine Candidate. Until the age of 15, many children suffer from recurrent strep throat infections. Up to three percent of ineffectively treated strep throat cases progress to rheumatic fever, a debilitating heart disease, which worsens with each succeeding streptococcal infection. Since the advent of penicillin therapy, rheumatic fever in the United States has experienced a dramatic decline. However, in the last two decades, rheumatic fever has experienced a resurgence in the United States. Part of the reason for this is the latent presence of this organism in children who do not display symptoms of a sore throat, and, therefore, remain untreated and at risk for development of rheumatic fever. Based on data from the Centers for Disease Control and Prevention, there are five to 10 million cases of pharyngitis due to group A streptococcus in the United States each year. There are over 32 million children in the principal age group targeted by us for vaccination. Worldwide, it is estimated that one percent of all school age children in the developing world have rheumatic heart disease. Additionally, despite the relative ease of treating strep throat with antibiotics, the specter of antibiotic resistance is always present. In fact, resistance to erythromycin, the second line antibiotic in patients allergic to penicillin, has appeared in a number of cases. o We believe that the reason no vaccine for strep throat has been developed is because of problems associated with identifying an antigen that is common to the more than 120 different serotypes of group A streptococcus, the bacterium that causes the disease. We have licensed from Rockefeller a proprietary antigen which is common to most types of group A streptococcus, including types that have been associated with rheumatic fever. When this antigen was orally administered to animals, it was shown to provide protection against multiple types of group A streptococcal infection. Using this antigen, we are seeking to develop a mucosal vaccine for strep throat. o SIGA has taken a parallel vaccine development track with two formulations of the cross-protective streptococcal antigen. One approach expresses the strep throat antigen on the surface of the commensal bacterium, Streptococcus gordonii, which lives on the surface of the teeth and gums. Pre-clinical research in mice and rabbits has established the ability of this vaccine candidate to colonize and induce both a local and systemic immune response. The other candidate uses a subunit (purified protein) approach, in which the antigen is delivered intranasally with a mucosal adjuvant (enhances the immune response). Like the commensal approach, the subunit approach has provided significant protection in mice from challenges by multiple serotypes. We are collaborating with the National Institutes of Health ("NIH") and the University of Maryland Center for Vaccine Development on the clinical development of this vaccine candidate. In cooperation with the NIH we filed an Investigational New Drug Application ("IND") with the FDA in December 1997. The first stage of these clinical trials, using the commensal delivery system without the strep throat antigen, were completed at the University of Maryland in 2000. The study showed the commensal delivery system to be well-tolerated and that it spontaneously eradicated or was easily eradicated by conventional antibiotics. A second clinical trial of the commensal delivery system without the strep throat antigen was initiated in 2000 at the University of Maryland. The study was completed in January 2002 and the results corroborated the results of the earlier study regarding tolerance and spontaneous eradication. Further development continues principally on the subunit approach, which is currently in pre-clinical studies. o In the U.S. there are about 19 million children aged 2 to 6 years who could be candidates to receive such a vaccine at the time of its introduction and then around 4 million babies born each year to be protected. Assuming a charge of $25 per dose and three doses needed for protection, there could be a potential market 7 for a strep throat vaccine of $1.4 billion to immunize the entire U.S. population of 2 to 6 year olds and, thereafter, $300 million per year to maintain immunization in new births. Surface Protein Expression System ("SPEX") The ability to overproduce many bacterial and human proteins has been made possible through the use of recombinant DNA technology. The introduction of DNA molecules into E. coli has been the method of choice to express a variety of gene products, because of these bacteria's rapid reproduction and well-understood genetics. Yet despite the development of many efficient E. coli-based gene expression systems, the most important concern continues to be associated with subsequent purification of the product. Recombinant proteins produced in this manner do not readily cross E. coli's outer membrane, and as a result, proteins must be purified from the bacterial cytoplasm or periplasmic space. Purification of proteins from these cellular compartments can be very difficult. Frequently encountered problems include low product yields, contamination with potentially toxic cellular material (i.e., endotoxin) and the formation of large amounts of partially folded polypeptide chains in non-active aggregates termed inclusion bodies. To overcome these problems, we have taken advantage of our knowledge of Gram-positive bacterial protein expression and anchoring pathways. This pathway has evolved to handle the transport of surface proteins that vary widely in size, structure and function. Modifying the approach used to create commensal mucosal vaccines, we have developed methods which, instead of anchoring the foreign protein to the surface of the recombinant Gram-positive bacteria, result in it being secreted into the surrounding medium in a manner which is readily amenable to simple batch purification. We believe the advantages of this approach include the ease and lower cost of Gram-positive bacterial growth, the likelihood that secreted recombinant proteins will be folded properly, and the ability to purify recombinant proteins from the culture medium without having to disrupt the bacterial cells and liberating cellular contaminants. Gram-positive bacteria may be grown simply in scales from those required for laboratory research up to commercial mass production. Collaborative Research and Licenses We have entered into the following license agreements and collaborative research arrangements: Rockefeller University. In accordance with an exclusive worldwide license agreement with Rockefeller, we have obtained the right and license to make, use and sell mucosal vaccines based on gram-positive organisms and products for the therapy, prevention and diagnosis of diseases caused by streptococcus, staphylococcus and other organisms. The license covers eight issued U.S. patents and three issued European patents, as well as one pending U.S. patent application and one pending European application. The issued United States patents expire in 2008, 2014 (4), 2015 (2), and 2016. respectively. The agreement generally requires us to pay royalties on sales of products developed from the licensed technologies, and fees on revenues from sublicensees, where applicable, and we are responsible for the costs of filing and prosecuting patent applications. The agreement also requires us to pay 15% of certain milestone payments we receive from Wyeth to Rockefeller, if any, under our collaborative and license agreement with Wyeth. Accordingly, under the agreement, which is our only agreement that requires us to make milestone payments, we could be required to make milestone payments to Rockefeller of up to an aggregate amount of approximately $1.1 million. To date, we have not received any milestone payments from Wyeth that would require us to make a payment to Rockefeller. The primary potential products from this collaboration are the strep vaccine and the broad spectrum antibiotic. Under the agreement, we paid the university approximately $850,000 to support research at Rockefeller. The agreement to fund research has ended and no payments have been made to the university since the year ended December 31, 1999. Under the agreement we are obligated to pay Rockefeller a royalty on net sales by SIGA at rates between 2.5% and 5% depending on product and amount of sales. On sales by any sub-licensee, we will pay Rockefeller a royalty of 15% of anything we receive. The term of the agreement is for the duration of the patents licensed. As we do not currently know when any patents pending or future patents will expire, we cannot at this time determine the term of this agreement. At the end of that term of the agreement, we have the right to continue to practice the then existing technical information as a fully paid, perpetual license. The agreement can be terminated earlier if we are in breach of the provisions of the agreement and do not cure the breach in the allowed cure period. We are compliant in all our obligations under the agreement. 8 Oregon State University. Oregon State University ("OSU") is also a party to our license agreement with Rockefeller, whereby we have obtained the right and license to make, use and sell products for the therapy, prevention and diagnosis of diseases caused by streptococcus. Pursuant to a separate research support agreement with OSU, we provided funding for sponsored research through December 31, 1999, with exclusive license rights to all inventions and discoveries resulting from this research. At this time, no additional funding is contemplated under this agreement, however, we retain the exclusive licensing rights to the inventions and discoveries that may arise from this collaboration. The term of the agreement is for the duration of the patents licensed. As we do not currently know when any patents pending or future patents will expire, we cannot at this time determine the term of this agreement. The agreement can be terminated earlier if we are in breach of the provisions of the agreement and do not cure the breach in the allowed cure period. We are compliant in all our obligations under the agreement. During 1999, we acquired an option to enter into a license with OSU in which we will acquire the rights to certain technology pertaining to the potential development of a chlamydia vaccine. In February 2000, we exercised our option and pursuant to an exclusive license agreement dated March 2000, we have made payments to OSU of approximately $25,000 as part of our obligation under the option. In September 2000, we entered into a subcontract with OSU. The contract is for a project which is targeted towards developing novel antiviral drugs capable of preventing disease and pathology for Smallpox in the event this pathogen were to be used as an agent of bioterrorism. The project is being funded by a grant from the NIH. The basic virology aspects of the project will be conducted at OSU and the drug development will be performed by us under the subcontract. The budget for the subcontract work was negotiated on a year by year basis with OSU and depended on the progress of the program and funding available. In the year ended December 31, 2001 we recognized revenue of $15,000. On October 5, 2001 the agreement was extended through August 31, 2002. For the period ended December 31, 2002 we recognized $75,000 in revenue. The agreement was extended again through August 31, 2003. The sub-contract is on a year to year renewal. Through December 31, 2003 we received a total of $130,000 under the agreement. During the year ended December 31, 2003 work under the subcontract was completed. Wyeth. We have entered into a collaborative research and license agreement with Wyeth in connection with the discovery and development of anti-infectives for the treatment of gram-positive bacterial infections. Pursuant to the agreement, Wyeth provided funding for a joint research and development program, subject to certain milestones, through September 30, 1999 and is responsible for additional milestone payments. In May 2001, we entered into an amendment to the July 1, 1997 agreement. The amendment extended the term of the original agreement to September 30, 2001. The extension provided for Wyeth to continue to pay us at a rate of $450,000 per year through the term of the amended agreement. During the term of the agreement as amended, we received $787,500 from Wyeth to support work performed by SIGA under the agreement and $237,500 for achieving a research milestone. For the year ended December 31, 2001 we recognized revenue of $1,025,000. The agreement to fund additional research was not extended beyond September 30, 2001. Wyeth is obligated to make milestone payments to us as any product developed progresses through the FDA approval process under our agreement with Wyeth, which is the only agreement pursuant to which we are entitled to receive milestone payments. For products developed we could receive up to approximately $13 million in milestone payments for approval of the product in the U.S. and Japan. We would also receive royalty payments of 2% on the first $300,000 of cumulative licensed product sales, 4% on annual sales up to $100 million, 6% on annual sales between $100 million and $250 million and 8% on annual sales above $250 million. The license will expire on the earlier of 10 years or the last to expire issued patent. Wyeth has the right to terminate the agreement early, on ninety days written notice. If terminated early, all rights granted to Wyeth revert to SIGA except with respect to any compound identified by Wyeth as of the date of termination and subject to the milestone and royalty obligations of the agreement. National Institutes of Health. We have entered into a clinical trials agreement with the NIH pursuant to which the NIH, with our cooperation, will conduct clinical trials of our strep throat vaccine candidate. The agreement will fund trials through Phase II of the FDA approval process. To date, two Phase I clinical trials have been conducted for the strep vaccine delivery system. We are working to optimize and test the vaccine formulation prior to initiating Phase I clinical trials with the recombinant commensal vector based vaccine. The agreement may 9 be terminated unilaterally by the parties upon sixty days prior notice. If terminated we will receive copies of all data, reports and other information related to the trials and any unused vaccine. Prior to 2002 we received grants amounting to $247,000 to support our antibiotic and vaccine development programs. In June 2002, we received a Phase II Small Business Innovation Research (SBIR) grant for approximately $865,000. The grant was for the two year period beginning June, 1, 2002 and ending May 31, 2004. In August 2004 we were awarded two Phase I and two Phase II grants totaling approximately $12.1 million to support our work on Smallpox and Arenaviruses. The grants were acquired as part of our acquisition of certain assets from ViroPharma Incorporated ("Viropharma"). For the years ending December 31, 2004, 2003 and, 2002, we have recognized revenue from the SBIR grants of $1,415,000, $388,000 and $270,000, respectively. As part of our operational strategy we routinely submit grants to the NIH. There is no assurance that we will receive additional grants. Washington University. In February 1998, we entered into a research collaboration and worldwide license agreement with Washington University pursuant to which we obtained the right and license to make, use and sell antibiotic products based on gram-negative technology for all human and veterinary diagnostic and therapeutic uses. The license covered five pending United States patent applications and corresponding foreign patent applications. The agreement generally required us to pay royalties on sales of products developed from the licensed technologies and fees on revenues from sublicensees, where applicable, and we were responsible for certain milestone payments and for the costs of filing and prosecuting patent applications. Pursuant to the agreement, we agreed to provide funding to Washington University for sponsored research through February 6, 2001, with exclusive license rights to all inventions and discoveries resulting from this research. During 1999, a dispute arose between the parties regarding their respective performance under the agreement. In February 2000, the parties reached a settlement agreement and mutual release of their obligations under the research collaboration agreement. Under the terms of the settlement, we are released from any further payments to Washington University and have disclaimed any rights to the patents licensed under the original agreement. As part of the settlement agreement, we entered into a non-exclusive license to certain patents covered in the original agreement. SIGA and Washington University will share equally the responsibility for the administration and the expenses for the prosecution of patent applications and /or patents in the agreement. The collaboration is for the gram-negative product opportunity. We will receive licensing revenue from Washington University that derives from the commercialization of products covered by patent rights of the agreement. The royalty will be 20% of the first $400,000 received and 10% of the next $1,000,000 received with a total payment of licensing revenues to us not to exceed $500,000. The term of our agreement with Washington University is for the duration of the patents and a number of pending patents. As we do not currently know when any patents pending or future patents will expire, we cannot at this time definitively determine the term of this agreement. The agreement cannot be terminated unless we fail to pay our share of the joint patent costs for the technology licensed. We have currently met all our obligations under this agreement. Abbott Laboratories. In March 2000, we entered into an agreement with the Ross Products Division of Abbott Laboratories ("Ross"). The agreement grants Ross an exclusive option to negotiate an exclusive license to certain SIGA technology and patents in addition to certain research development services. In exchange for research services and the option, Ross was obligated to pay us $120,000 in three installments of $40,000. The first payment of $40,000 was received in March 2000 and was recognized ratably, over the term of the arrangement. The remaining installments are contingent upon meeting certain milestones under the agreement and will be recognized as revenue upon completion and acceptance of such milestones. The first milestone was met, and we received an additional payment of $40,000 in the quarter ended September 30, 2000. During the years ended December 31, 2001 and 2000, we recognized revenue in the amount of $45,000 and $80,000, respectively. The development agreement was for a sexually transmitted disease potential product opportunity. The research program was completed in late 2001 and additional work was performed into 2003, however the additional work could not be completed due to the inability of one of our sub-contractors to perform. As a result, we gave Ross notice of termination on January 26, 2004 and all rights to the technology reverted to us. Regents of the University of California. In December 2000, we entered into an exclusive license agreement and a sponsored research agreement with the Regents of the University of California ("Regents"). Under the license agreement we obtained rights for the exclusive commercial development, use and sale of products related to certain inventions in exchange for a non-refundable license issuance fee of $15,000 and an annual maintenance 10 fee of $10,000. As of December 31, 2004 we have made payments of approximately $91,000 under the license. In the event that we sub-license the license, we must pay Regents 15% of all royalty payments made to SIGA. Under the agreement, we will also pay Regents 15% of all royalties received from Wyeth. The agreement applies to the gram positive product opportunity and our collaborative agreement with Wyeth. The term of the agreement is until the expiration of the last-to-expire patent licensed under this agreement. The agreement may be terminated by Regents if we default on any of our obligations, the agreement with Wyeth is terminated and a substitute agreement is not entered into or if we give notice that we do not intend to make product from the licensed technology. We have currently met all our obligations under this agreement. U.S. Army Medical Research Acquisition Activity. In December 2002, we entered into a four years contract with the U.S. Army Medical Research Acquisition Activity (USAMRAA) to develop a drug to treat Smallpox. The contract start date was January 1, 2003 and the total amount approximated $1.6 million. Annual payments over the term of the agreement will be approximately $400,000. TransTech Pharma, Inc. In October 2002, we entered into a drug discovery collaboration agreement with TransTech Pharma, Inc. ("TransTech Pharma"). Under the agreement, SIGA and TransTech Pharma collaborate on the discovery, optimization and development of lead compounds to therapeutic agents. The costs of development are shared. SIGA and TransTech Pharma would share revenues generated from licensing and profits from any commercialized product sales. The agreement will be in effect until terminated by the parties or upon cessation of research or sales of all products developed under the agreement. If the agreement is terminated, relinquished or expires for any reason certain rights and benefits will survive the termination. Obligations not expressly indicated to survive the agreement will terminate with the agreement. No revenues were recognized in 2004, 2003 and 2002 from this collaboration. Intellectual Property and Proprietary Rights Our commercial success will depend in part on our and our collaborators' ability to obtain and maintain patent protection for our proprietary technologies, drug targets and potential products and to effectively preserve our trade secrets. Because of the substantial length of time and expense associated with bringing potential products through the development and regulatory clearance processes to reach the marketplace, the pharmaceutical industry places considerable importance on obtaining patent and trade secret protection. The patent positions of pharmaceutical and biotechnology companies can be highly uncertain and involve complex legal and factual questions. No consistent policy regarding the breadth of claims allowed in biotechnology patents has emerged to date. Accordingly, we cannot predict the type and breadth of claims allowed in these patents. We have licensed the rights to eight issued U.S. patents and three issued European patents. These patents have varying lives and they are related to the technology licensed from Rockefeller University for the Strep and Gram-positive products. We have one additional patent application in the U.S. and one application in Europe relating to this technology. We are joint owner with Washington University of seven issued patents in the U.S. and one in Europe. In addition, there are four co-owned U.S. patent applications. These patents are for the technology used for the gram-negative product opportunities. We are also exclusive owner of one U.S. patent and three U.S. patent applications. One of these U.S. patent applications relates to our DegP product opportunities. The following are our patent positions as of December 31, 2004. 11 ---------------------------------------------------------------------------------------------------------------------- Number Number Number Exclusively Number Exclusively Co-Exclusively Licensed Exclusively Number PATENTS Licensed Licensed from Licensed Owned by Patent Expiration Dates from with Oregon from UCLA SIGA Rockefeller Washington State Univ.

No assurance can be given that other companies will not independently develop substantially equivalent proprietary information and techniques or otherwise gain access to our trade secrets or that we can meaningfully protect our trade secrets. Government Regulation Regulation by governmental authorities in the United States and other countries will be a significant factor in the production and marketing of any biopharmaceutical products that we may develop. The nature and the extent to which such regulations may apply to us will vary depending on the nature of any such products. Virtually all of our potential biopharmaceutical products will require regulatory approval by governmental agencies prior to commercialization. In particular, human therapeutic products are subject to rigorous pre-clinical and clinical testing and other approval procedures by the FDA and similar health authorities in foreign countries. Various federal statutes and regulations also govern or influence the manufacturing, safety, labeling, storage, record keeping and marketing of such products. The process of obtaining these approvals and the subsequent compliance with appropriate federal and foreign statutes and regulations requires the expenditure of substantial resources. 12 ---------------------------------------------------------------------------------------------------------------------- Number Number Number Exclusively Number Exclusively Co-Exclusively Licensed Exclusively Number PATENTS Licensed Licensed from Licensed Owned by Patent Expiration Dates from with Oregon from UCLA SIGA Rockefeller Washington State Univ.

Before beginning human clinical testing of a potential new drug, a company must file an IND and receive clearance from the FDA. This application is a summary of the pre-clinical studies that were conducted to characterize the drug, including toxicity and safety studies, as well as an in-depth discussion of the human clinical studies that are being proposed. The pre-marketing program required for approval by the FDA of a new drug typically involves a time-consuming and costly three-phase process. In Phase I, trials are conducted with a small number of patients to determine the early safety profile, the pattern of drug distribution and metabolism. In Phase II, trials are conducted with small groups of patients afflicted with a target disease in order to determine preliminary efficacy, optimal dosages and expanded evidence of safety. In Phase III, large scale, multi-center comparative trials are conducted with patients afflicted with a target disease in order to provide enough data for statistical proof of efficacy and safety required by the FDA and others. The FDA has amended its regulations, effective June 30, 2002, so that certain new drug and biological products used to reduce or prevent the toxicity of chemical, biological, radiological, or nuclear substances may be approved for use in humans based on evidence of effectiveness derived only from appropriate animal studies and any additional supporting data. To date, the FDA has not given clearance to any products submitted under the amended regulations. The FDA closely monitors the progress of each of the three phases of clinical testing and may, in its discretion, reevaluate, alter, suspend or terminate the testing based on the data that have been accumulated to that point and its assessment of the risk/benefit ratio to the patient. Estimates of the total time required for carrying out such clinical testing vary between two and ten years. Upon completion of such clinical testing, a company typically submits a New Drug Application ("NDA") or Product License Application ("PLA") to the FDA that summarizes the results and observations of the drug during the clinical testing. Based on its review of the NDA or PLA, the FDA will decide whether to approve the drug. This review process can be quite lengthy, and approval for the production and marketing of a new pharmaceutical product can require a number of years and substantial funding; there can be no assurance that any approvals will be granted on a timely basis, if at all. Once the product is approved for sale, FDA regulations govern the production process and marketing activities, and a post-marketing testing and surveillance program may be required to monitor continuously a product's usage and its effects. Product approvals may be withdrawn if compliance with regulatory standards is not maintained. Other countries in which any products developed by us may be marketed could impose a similar regulatory process. Commercialization of animal health products can be accomplished more rapidly than human health products. Unlike the human market, potential vaccine or therapeutic products can be tested directly on the target animal as soon as the product leaves the research laboratory. The data collected in these trials is submitted to the U.S. Department of Agriculture for review and eventual product approval. Competition The biotechnology and pharmaceutical industries are characterized by rapidly evolving technology and intense competition. Our competitors include most of the major pharmaceutical companies, which have financial, technical and marketing resources significantly greater than ours. Biotechnology and other pharmaceutical competitors include Acambis, AVI Biopharma, Avant Immuno-therapeutics, Inc, Bavarian Nordic AS, Chimerix Inc., Dynport Vaccine Company, Bioport, Dor Biopharma, Inc., Pharmathene, and Microbiotix, Inc. Academic institutions, governmental agencies and other public and private research organizations are also conducting research activities and seeking patent protection and may commercialize products on their own or through joint venture. There can be no assurance that our competitors will not succeed in developing products that are more effective or less costly than any which are being developed by us or which would render our technology and future products obsolete and noncompetitive. 13 Human Resources and Facilities As of March 14, 2005 we had 35 full time employees. None of our employees are covered by a collective bargaining agreement and we consider our employee relations to be good.

Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities Price Range of Common Stock Our common stock has been traded on the Nasdaq SmallCap Market since September 9, 1997 and trades under the symbol "SIGA." Prior to that time there was no public market for our common stock. The following table sets forth, for the periods indicated, the high and low closing sales prices for the common stock, as reported on the Nasdaq SmallCap Market. As of March 28, 2005, the closing bid price of our common stock was $1.53 per share. There were 106 holders of record as of March 28, 2005. We believe that the number of beneficial owners of our common stock is substantially greater than the number of record holders, because a large portion of common stock is held in broker "street names." We have paid no dividends on our common stock and we do not expect to pay cash dividends in the foreseeable future. We are not under any contractual restriction as to our present or future ability to pay dividends. We currently intend to retain any future earnings to finance the growth and development of our business. Recent Sales of Unregistered Securities All of the following sales of unregistered securities were made without registration under the Securities Act in reliance upon the exemption from registration afforded under Section 4(6) of the Securities Act and Rule 506 of Regulation D promulgated thereunder. Accordingly, the transfer of the securities is subject to substantial restrictions. Securities were only purchased by "Accredited Investors" as that term is defined under Rule 501 of Regulation D. Proceeds from the offerings were used for general working capital purposes. In August 2004, we acquired certain government grants and two early stage antiviral programs, Smallpox and Arenavirus, targeting certain agents of biological warfare from ViroPharma. As part of the purchase price for these assets they were issued 1,000,000 shares of our common stock. In August 2003, we entered into an agreement with MacAndrews & Forbes Holdings Inc. ("MacAndrews & Forbes"), a holding company of which the Company's Chairman of the Board of Directors is Vice Chairman and a director. Upon consummation of the agreement, MacAndrews & Forbes and its permitted assignees invested an initial $1,000,000 in SIGA in exchange for 694,444 shares of our common stock at a price of $1.44 per share and warrants to purchase 347,222 shares of common stock at an initial exercise price of $2.00 per share. MacAndrews & Forbes and its permitted assignees also received an option, exercisable through October 13, 2003, to invest up to an additional $9,000,000 in SIGA on the same terms. Upon exercise of the option in October 2003, we received gross 16 Price Range 2003 High Low First Quarter ..................................... $ 1.49 $ 1.02 Second Quarter .................................... $ 1.91 $ 1.09 Third Quarter ..................................... $ 2.13 $ 1.61 Fourth Quarter .................................... $ 2.60 $ 1.80 2004 High Low First Quarter ..................................... $ 2.34 $ 1.85 Second Quarter .................................... $ 1.93 $ 1.29 Third Quarter ..................................... $ 1.63 $ 1.23 Fourth Quarter .................................... $ 1.75 $ 1.35 proceeds of $2,159,405 in exchange for 1,499,587 shares of common stock at a price of $1.44 per share and warrants to purchase 749,794 shares of common stock at an initial exercise price of $2.00 per share. In January 2004, upon approval of the Company's shareholders, MacAndrews & Forbes and its permitted assignee, TransTech Pharma, Inc., invested the remaining $6,840,595 in exchange for 4,750,413 shares of common stock and warrants to purchase 2,375,206 shares of common stock at an exercise price of $2.00 per share. All warrants issued under the agreement have a term of seven years. In June 2003, the Company raised gross proceeds of $1.5 million in a private offering of 1,250,000 shares of common stock. In connection with the offering the Company issued warrants to purchase 625,000 shares of the Company's common stock to placement agents. The warrants are exercisable at a price of $2.00 per share and have a term of five years. In May 2003, we acquired substantially all of the assets of Plexus in exchange for 1,950,000 shares of our common stock and the assumption of certain liabilities, including promissory notes for loans we previously made to Plexus for $50,000 and $20,000. In December 2002 and January 2003, we completed a private placement of 34 units consisting of 1.7 million shares of common stock to a group of private investors. The gross proceeds from the offering were $1,865,000 with net proceeds to SIGA of approximately $1,682,000. In October 2002, we completed a private placement of units consisting of an aggregate of 1,037,500 shares of 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. The offering yielded net proceeds of approximately $935,000. See Item 12 for certain equity compensation information with respect to equity compensation plans. Other Transactions In 2004, the Company reached a settlement agreement for breach of contract with a founder of the Company, whereby the founder returned 40,938 common shares, 150,000 warrants and $15,000 to the Company. The common shares were retired by the Company. The Company recorded the $15,000 settlement amount as other income. Item 6.

Management's Discussion and Analysis of Financial Condition and Results 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 Annual Report. In addition to historical information, the following discussion and other parts of this Annual Report contain forward-looking information that involves risks and uncertainties. Overview Since our inception in December 1995, we have been principally engaged in the research and development of novel products for the prevention and treatment of serious infectious diseases, including products for use in the defense against biological warfare agents such as Smallpox and Arenaviruses. The effort to develop a drug for Smallpox is being aided by SBIR grants from the NIH totaling approximately $5.8 million that were awarded in the third quarter of 2004 and a $1.6 million contract with the U.S. Army which began in January 2003. The Arenavirus program is being supported by SBIR grants from the NIH totaling approximately $6.3 million that were awarded in the third quarter of 2004. Our anti-viral programs are designed to prevent or limit the replication of the viral pathogen. Our anti-infectives programs are aimed at the increasingly serious problem of drug resistance. These programs are designed to block the ability of bacteria to attach to human tissue, the first step in the infection process. We are also developing a technology for the mucosal delivery of our vaccines which may allow the vaccines to activate the immune system at the mucus lined surfaces of the body -- the mouth, the nose, the lungs and the gastrointestinal and urogenital tracts -- the sites of entry for most infectious agents. We do not have commercial biomedical products, 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 and projected cash flows to support operations beyond December 31, 2005. 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 antiviral, antibiotic and vaccine 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 manufacturing 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. 18 Total Net cash used As of and for the year Cash & cash stockholders' in operating ended December 31, Total assets equivalents equity activities ------------------ ------------ ----------- ------------- ------------- 2004 $ 6,111 $ 2,021 $ 4,559 $ (4,890) 2003 $ 6,100 $ 1,441 $ 5,551 $ (5,332) 2002 $ 2,830 $ 2,069 $ 2,173 $ (2,648) 2001 $ 4,208 $ 3,148 $ 3,541 $ (2,944) 2000 $ 3,210 $ 1,707 $ 925 $ (3,938) Accordingly, we expect to incur operating losses for the foreseeable future. There can be no assurance that we will ever achieve profitable operations. Critical Accounting Estimates The methods, estimates and judgments we use in applying our accounting policies have a significant impact on the results we report in our financial statements, which we discuss under the heading "Results of Operations" following this section of our MD&A. Some of our accounting policies require us to make difficult and subjective judgments, often as a result of the need to make estimates of matters that are inherently uncertain. Our most critical accounting estimates include the assessment of recoverability of goodwill, which impacts goodwill impairments; assessment of recoverability of long-lived assets, which primarily impacts operating income when we impair intangible assets. Below, we discuss these policies further, as well as the estimates and judgments involved. We also have other policies that we consider key accounting policies, such as for revenue recognition; however, these policies do not require us to make estimates or judgments that are difficult or subjective. Significant Accounting Policies The following is a brief discussion of the more significant accounting policies and methods used by us in the preparation of our financial statements. Note 2 of the Notes to the Consolidated Financial Statements includes a summary of all of the significant accounting policies. Revenue Recognition The Company recognizes revenue from contract research and development and research progress payments in accordance with SEC Staff Accounting Bulletin No. 104, Revenue Recognition, ("SAB 104"). In accordance with SAB 104, revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed and determinable, collectibility is reasonably assured, contractual obligations have been satisfied and title and risk of loss have been transferred to the customer. The Company recognizes revenue from non-refundable up-front payments, not tied to achieving a specific performance milestone, over the period which the Company is obligated to perform services or based on the percentage of costs incurred to date, estimated costs to complete and total expected contract revenue. Payments for development activities are recognized as revenue is earned, over the period of effort. Substantive at-risk milestone payments, which are based on achieving a specific performance milestone, are recognized as revenue when the milestone is achieved and the related payment is due, providing there is no future service obligation associated with that milestone. In situations where the Company receives payment in advance of the performance of services, such amounts are deferred and recognized as revenue as the related services are performed. Goodwill Goodwill is recorded when the purchase price paid for an acquisition exceeds the estimated fair value of the net identified tangible and intangible assets acquired. The Company performs an annual review in the fourth quarter of each year, or more frequently if indicators of potential impairment exist, to determine if the carrying value of the recorded goodwill is impaired. Goodwill impairment is determined using a two-step approach in accordance with Statement of Financial Accounting Standards No. 142 "Goodwill and Other Intangible Assets" ("SFAS 142"). The impairment review process compares the fair value of the reporting unit in which goodwill resides to its carrying value. In 2004, the Company operated as one business and one reporting unit. Therefore, the goodwill impairment analysis was performed on the basis of the Company as a whole using the market capitalization of the Company as an estimate of its fair value. The estimated fair values might produce significantly different results if other reasonable assumptions and estimates were to be used. Identified Intangible Assets Acquisition-related intangibles include acquired technology, customer contracts, grants and covenants not to compete, and are amortized on a straight line basis over periods ranging from 3.5-4 years. 19 In accordance with Statement of Financial Accounting Standards No. 144 "Accounting for the Impairment or Disposal of Long-Lived Assets" ("SFAS 144"), the Company performs a review of its identified intangible assets to determine if facts and circumstances exist which indicate that the useful life is shorter than originally estimated or that the carrying amount of assets may not be recoverable. If such facts and circumstances do exist, the Company assesses the recoverability of identified intangible assets by comparing the projected undiscounted net cash flows associated with the related asset or group of assets over their remaining lives against their respective carrying amounts. Impairment, if any, is based on the excess of the carrying amount over the fair value of those assets. Recent Accounting Pronouncements In December 2004, the FASB issued SFAS No. 123R, "Share-Based Payment." SFAS No. 123R requires employee stock options and rights to purchase shares under stock participation plans to be accounted for under the fair value method, and eliminates the ability to account for these instruments under the intrinsic value method prescribed by APB Opinion No. 25, and allowed under the original provisions of SFAS No. 123. SFAS No. 123R requires the use of an option pricing model for estimating fair value, which is amortized to expense over the service periods. The requirements of SFAS No. 123R are effective for fiscal periods beginning after June 15, 2005. SFAS No. 123R allows for either prospective recognition of compensation expense or retrospective recognition, which may be back to the original issuance of SFAS No. 123 or only to interim periods in the year of adoption. The Company is currently evaluating these transition methods. In March 2004, the Emerging Issues Task Force issued EITF 03-06, "Participating Securities and the Two-Class Method under FASB Statement No. 128". This statement provides additional guidance on the calculation and disclosure requirements for earnings per share. The FASB concluded in EITF 03-06 that companies with multiple classes of common stock or participating securities, as defined by SFAS No. 128, calculate and disclose earnings per share based on the two-class method. The adoption of this statement did not have an impact to our financial statements presentation as the Company is in a loss position. Results of Operations The following table sets forth certain consolidated statements of income data as a percentage of net revenue for the periods indicated: Years ended December 31, 2004, 2003 and 2002 Revenues from grants and research and development contracts approximated $1,839,200 for the year ended December 31, 2004 compared to $731,700 for the year ended December 31, 2003. The approximate 151% increase is the result of the award of two Phase I and two Phase II SBIR grants by the NIH during the third quarter of 2004. The Phase II grants are for a two year period ending in the third quarter of 2006. The total grant award was for approximately $12.1 million. For the year ended December 31, 2004 we recorded revenue of $1,049,600 from these grants. We also received a one year SBIR grant from the NIH for $252,000 in August 2004 to support our Strep vaccine program. For the year ended December 31, 2004 we recorded revenue of $85,600 from this grant. Revenue from our contract with the U.S. Army was $425,100 for 2004; compared to $315,300 for the year ended December 31, 2003. The approximate 35% increase was due to the higher budget for work performed in 2004. For the year ended December 31, 2004 we received revenue of $254,800 from an SBIR grant for our DegP anti infective that we 20 2004 2003 2002 ---------- ---------- ---------- Revenue 100% 100% 100% ---------- ---------- ---------- Selling, general and administrative 220% 362% 534% Research and development 227% 402% 513% Patent preparation fees 21% 41% 31% In-process research and development 31% 0% 0% Impairment of intangible assets 115% 19% 0% ---------- ---------- ---------- Operating loss 514% 723% 978% completed in the second quarter of 2004. For the year ended December 31, 2003 we received $387,800 from this grant. Revenue of $731,700 for the year ended December 31, 2003 was approximately 112% higher than revenue of $344,450 for the year ended December 31, 2002. The increase for the year ended December 31, 2003 from the prior year reflects $290,000 in revenue from the first year of our $1.6 million contract with the U.S. Army for our work on the development of a Smallpox drug. Revenue from our Phase II Small Business Innovation Research (SBIR) grant also increased. Revenue from the SBIR grant for the year ended December 31, 2003 was approximately $388,000, an approximate 44% increase over the year ended December 31, 2002. The SBIR grant, which was a two year grant for a total of $865,000, ended on May 31, 2004. Selling, general and administrative expenses for the year ended December 31, 2004 were $4,042,000 compared to expenses of $2,646,600 for the year ended December 31, 2003. The increase of $1,395,400, or approximately 53%, was primarily due to an increase of $628,000 in payroll expense, and a $693,000 increase in legal expenses. Payroll expenses increased by approximately 128% primarily due to the addition of a Chief Executive Officer and a Vice President - Business Development, bonuses paid to employees, and the costs associated with the termination of the Employment Agreement with our former President. The increase in legal expenses of 272% from 2003 was the result of the costs incurred to review and amend our corporate governance policies and procedures to ensure compliance with the regulations promulgated under the Sarbanes Oxley Act of 2002, as well as the NASDAQ stock market. Also contributing to the increase in legal expenses were the costs incurred in connection with a potential business combination, the sale of certain non-core vaccine assets, the hiring of our new CEO, a legal action that we initiated against a former founder and the work performed relative to the acquisition of certain assets and grants from ViroPharma. Increases in travel expense, rent, amortization and filing fees were offset by decreases in depreciation, insurance and miscellaneous expenses. The $2,646,600 of selling, general and administrative expenses incurred for the year ended December 31, 2003 represented an increase of approximately 44% from an expense of $1,838,500 for the year ended December 31, 2002. Of the $808,100 increase, approximately $553,000 was the result of higher consulting expenses associated with our marketing program to find additional sources of government grant and contract funding and increased investor relations efforts. Approximately $184,000 of the increase was the result of increased payroll expense reflecting the administrative employees who were added in connection with the acquisition of substantially all the assets of Plexus. In addition, the year ended December 31, 2003 included non-cash expenses of approximately $123,000 associated with the amortization of certain intangible assets acquired in the Plexus transaction. These increases were partially offset by lower legal and accounting fees. For the year ended December 31, 2002 legal and accounting fees were approximately $176,000 higher than the expenses incurred in 2003 as the result of work done in 2002 on a proposed merger. Research and development expenses were $4,165,800 for the year ended December 31, 2004; an increase of approximately 42% from the $2,942,800 of expenses incurred for the year ended December 31, 2003. Amortization expense of $635,900 represented approximately 35% of the increase. These expenses were the result of the acquisition of certain assets from Plexus in 2003 and ViroPharma in 2004. Payroll expenses increased approximately 28% to $1,654,000 for 2004 from $1,289,700 incurred in 2003. The increase was the result of the expansion of staff to service the grants acquired from ViroPharma and bonuses paid to employees. Sponsored research increased by approximately 117% in 2004 to $486,000 from $223,500 in 2003. The increase was the result of payments made to a Danish university for former Plexus programs, a payment made to TransTech Pharma for work performed on an SBIR grant that was completed in the second quarter and payments to Oregon State University for work on the strep grant received in 2004. Expenses for lab supplies increased approximately 16% to $472,890 from $407,076 as a result of accelerated development of our lead product programs. For the year ended December 31, 2003 research and development expenses increased approximately 67% to $2,942,800 from $1,766,400 for the same period in 2002. Approximately $504,000 of the increase was the result of 64% higher payroll expense caused by the addition of Plexus R&D personnel as well as additional staffing for our ongoing Smallpox and anti-infectives programs. For the year ended December 31, 2003 we recognized non-cash charges of approximately $262,000 for the amortization of certain intangible assets acquired from Plexus; no similar charges were recognized in the prior year. In addition, lab supply expenses were approximately $400,000, an increase of approximately 83% in the year ended December 31, 2003 from the prior year spending level of 21 approximately $219,000. The increase reflects increased activity on our Smallpox and DegP programs. Sponsored research increased to approximately $315,000, an 82% increase from the prior year. The increase was due to payment for work being performed on former Plexus programs at a Danish University. All of our product programs are in the early stage of development. At this stage of development, we cannot make estimates of the potential cost for any program to be completed or the time it will take to complete the project. There is a high risk of non-completion of any program because of the lead time to program completion and uncertainty of the costs. Net cash inflows from any products developed from these programs is at least one to three years away. However, we could receive additional grants, contracts or technology licenses in the short-term. The potential cash and timing is not known and we cannot be certain if they will ever occur. The risk of failure to complete any program is high, as each is in the relatively early stage of development. Products for the biological warfare defense market, such as the Smallpox anti-viral, could be available for sale in one to three years. We believe the products directed toward this market are on schedule. We expect the future research and development cost of this program to increase as the potential products enter animal studies and safety testing. Funds for future development will be partially paid for by NIH SBIR grants, the contract we have with the U.S. Army, additional government funding and from future financing. If we are unable to obtain additional federal grants and contracts or funding in the required amounts, the development timeline for these products would slow or possibly be suspended. The clinical trials for our Strep vaccine through Phase II would be funded under an agreement with the NIH. The time to market for this product should be several years from now because of the nature of the FDA requirements for approval of a pediatric vaccine. We expect to fund the development of the Strep vaccine beyond the Phase II clinical trials through a corporate collaboration or from additional funding from debt or equity financings. We do not yet have a corporate partner for this product and there is no assurance that we will ever have one or that we will be able to raise the funds needed to go forward. If the funding is not available or the clinical trials are not successful, the program could be delayed or cancelled. We believe this product program is on schedule. Delay or suspension of any of our programs could have an adverse impact on our ability to raise funds in the future, enter into collaborations with corporate partners or obtain additional federal funding from contracts or grants. Patent preparation expenses for the year ended December 31, 2004 were $393,100 an approximate 31% increase from expenses of $300,500 incurred in 2003. The increase was the result of increased costs arising from the Plexus and ViroPharma asset acquisitions. The $300,500 of expense incurred in 2003 was an approximate 187% increase over the $104,700 expense incurred in 2002, the result of increased costs of patent work required on the intellectual property acquired in the Plexus transaction, including foreign patent filings. For the year ended December 31, 2004, as a result of the acquisition of certain government grants and two early stage antiviral programs, Smallpox and Arenavirus, targeting certain agents of biological warfare, from ViroPharma, $568,329 was immediately expensed as purchased in-process research and development ("IPRD"). The amount expensed as IPRD was attributed to technology that has not reached technological feasibility and has no alternate future use. The value allocated to IPRD was determined using the income approach that included an excess earnings analysis reflecting the appropriate costs of capital for the purchase. Estimates of future cash flows related to the IPRD were made for both the Smallpox and Arenavirus programs. The aggregate discount rate of approximately 55% utilized to discount the programs' cash flows were based on consideration of the Company's weighted average cost of capital, as well as other factors, including the stage of completion and the uncertainty of technology advances for these programs. If the programs are not successful or completed in a timely manner, the Company's product pricing and growth rates may not be achieved and the Company may not realize the financial benefits expected from the programs. For the year ended December 31, 2004 we recorded a $2,118,200 non-cash loss on impairment of assets. In December 2004, upon completion of the ViroPharma transaction, integration of the related acquired programs into the Company's operations, and the demonstrated antiviral activity of the Company's lead smallpox compound against several mouse models of poxvirus disease, we commenced an application process for additional government grants to support our continued efforts under the Smallpox and Arenavirus antiviral programs. We determined that significant efforts and resources will be necessary to successfully continue the development efforts under these programs and decided to allocate the necessary resources to support its commitment. As a result, limited resources will be available for the development of future product candidates that utilize the technology acquired from Plexus 22 in May 2003. These factors resulted in a significant reduction in forecasted revenues related to that technology and a reduction in the future remaining useful life, and triggered the related intangible asset impairment. The amount of impairment recorded by us in December 2004 was determined using the two-step process impairment review as required by SFAS 144. In the first step, we compared the projected undiscounted net cash flows associated with the technology acquired from Plexus over its remaining life against its carrying amount. We determined that the carrying amount of the technology acquired from Plexus exceeded its projected undiscounted cash flows. In the second step, we estimated the fair value of the technology using the income method of valuation, which included the use of estimated discounted cash flows. Based on our assessment, we recorded a non-cash impairment charge of approximately $1.5 million in December 2004, which was included as a component of our operating loss. In May 2004, we performed an impairment review of our intangible assets in accordance with SFAS 144 in connection with the sale of certain intangible assets from our immunological bioinformatics technology and certain non-core vaccine development to a privately-held company, Pecos Labs, Inc. ("Pecos"). We recorded an impairment charge of $307,000 to the grants transferred to Pecos and $303,000 to the covenant not to compete with our President who was terminated during the current year period. For the year ended December 31, 2003, we incurred a loss on impairment of assets as a result of taking a non-cash charge of $137,000 to the intangible assets acquired in the Plexus transaction to reflect the termination of a research agreement. No similar charge was incurred in 2002. Total operating loss for the year ended December 31, 2004 was $9,448,300 compared to a loss of $5,294,900 for 2003. Of the current loss, $2,686,500 was the result of non-cash charges incurred for the impairment of assets and recognition of in-process research and development expense. Excluding these expenses, the current year loss was approximately 28% higher than the prior year. The increase in the loss was due to higher selling, general and administrative expenses, higher research and development expenses and higher patent costs as described in detail above. These increases were partially offset by increased revenue. Total operating loss for the year ended December 31, 2003 was $5,294,900, an approximate 57% increase from the $3,365,100 loss incurred for the year ended December 31, 2002. The increase in the loss is the result of higher selling, general and administration expenses and research and development expenses as described above, partially offset by higher revenues. Approximately 27% of the increase in the net loss was the result of non-cash charges incurred in the year ended December 31, 2003. Other income was $75,000 in the year ended December 31, 2004 an increase of approximately 311% from the $18,300 for the year ended December 31, 2003. The increase was mainly due to interest income related to higher cash balances during 2004 compared to 2003. In 2004 we also received other income of $15,000 as the result of the settlement of a legal action with a former founder. Other income of $18,300 for the year ended December 31, 2003 was approximately 46% lower than the $34,100 recognized for the year ended December 31, 2002 and reflected a reduction in interest income due to lower cash balances and interest yields in the year ended December 31, 2003 compared to prior year. Liquidity and Capital Resources As of December 31, 2004 we had $2,020,938 in cash and cash equivalents. We believe that these funds and our projected cash flows are sufficient to support our operations beyond December 31, 2005, and that sufficient cash flows will be available to meet our business objectives. In August 2004, we acquired certain government grants and two early stage antiviral programs, Smallpox and Arenavirus, targeting certain agents of biological warfare from ViroPharma for a purchase price of $1,000,000 in cash and 1,000,000 shares of our common stock. As part of the closing, we were awarded Phase I and II SBIR grants from the NIH totaling approximately $12.1 million, which will be received over the next two years, for the development of drugs for the treatment of Smallpox and Arenavirus as noted above. In May 2004, we sold intangible assets from our immunological bioinformatics technology and certain non-core vaccine development assets to a privately-held company, Pecos Labs, Inc. ("Pecos") in exchange for 150,000 shares of Pecos common stock. As a result of this transaction, we performed an impairment review of the intangible 23 assets and concluded that the carrying amount of certain transferred intangible assets of $307,063 would not be recoverable. In addition, we terminated our employment agreement with our President. We paid approximately $270,000 in severance to our former President as well as accelerated vesting on 100,000 stock options that were due to vest in May 2004. No compensation charge was recorded as the exercise price of the options was above the fair value market price on the date of termination. In addition, we reduced the covenant not to compete with our former President to one year from the date of termination. We recognized $303,000 of impairment to the unamortized covenant not to compete with our former President due to the reduction of the covenant to one year from the date of termination. In August 2003, we entered into an agreement with MacAndrews & Forbes Holdings Inc. ("MacAndrews & Forbes"), a holding company of which the Company's Chairman of the Board of Directors is Vice Chairman and a director. Upon consummation of the agreement, MacAndrews & Forbes and its permitted assignees invested an initial $1,000,000 in SIGA in exchange for 694,444 shares of our common stock at a price of $1.44 per share and warrants to purchase 347,222 shares of common stock at an initial exercise price of $2.00 per share. MacAndrews & Forbes and its permitted assignees also received an option, exercisable through October 13, 2003, to invest up to an additional $9,000,000 in SIGA on the same terms. Upon exercise of the option in October 2003, we received gross proceeds of $2,159,405 in exchange for 1,499,587 shares of common stock at a price of $1.44 per share and warrants to purchase 749,794 shares of common stock at an initial exercise price of $2.00 per share. In January 2004, upon approval of the Company's shareholders, MacAndrews & Forbes and its permitted assignees invested the remaining $6,840,595 in exchange for 4,750,413 shares of common stock and warrants to purchase 2,375,206 shares of common stock at an exercise price of $2.00 per share. All warrants issued under the agreement have a term of seven years. In June 2003, the Company raised gross proceeds of $1.5 million in a private offering of 1,250,000 shares of common stock. In connection with the offering, the Company issued warrants to purchase 625,000 shares of the Company's common stock to placement agents. The warrants are exercisable at a price of $2.00 per share and have a term of five years. In May 2003, we acquired substantially all of the assets of Plexus in exchange for 1,950,000 shares of our common stock and the assumption of certain liabilities, including promissory notes for loans we previously made to Plexus for $50,000 and $20,000. In December 2002 and January 2003, we completed a private placement of 34 units consisting of 1.7 million shares of common stock to a group of private investors. The gross proceeds from the offering were $1,865,000 with net proceeds to SIGA of approximately $1,682,000. We anticipate that our current resources will be sufficient to finance our currently anticipated needs for operating and capital expenditures approximately beyond December 31, 2005. In addition, we will attempt to generate additional working capital through a combination of collaborative agreements, 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. 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. 24 Contractual Obligations, Commercial Commitments and Purchase Obligations As of December 31, 2004, our purchase obligations are not material. We lease certain facilities and office space under operating leases. Minimum future rental commitments under operating leases having non-cancelable lease terms in excess of one year are as follows: Off-Balance Sheet Arrangements SIGA does not have any off-balance sheet arrangements. Risk Factors That May Affect Results of Operations and Financial Condition This report contains forward-looking statements and other prospective information relating to future events. These forward-looking statements and other information are subject to risks and uncertainties that could cause our actual results to differ materially from our historical results or currently anticipated results including the following: We have incurred operating losses since our inception and expect to incur net losses and negative cash flow for the foreseeable future. We incurred net losses of approximately $9.4 million, $5.3 million and $3.3 million for the years ended December 31, 2004, 2003 and 2002, respectively. As of December 31, 2004, 2003 and 2002, our accumulated deficit was approximately $44.2 million, $34.8 million and $29.5 million, respectively. We expect to continue to incur significant operating expenditures. We will need to generate significant revenues to achieve and maintain profitability. We cannot guarantee that we will achieve sufficient revenues for profitability. Even if we do achieve profitability, we cannot guarantee that we can sustain or increase profitability on a quarterly or annual basis in the future. If revenues grow slower than we anticipate, or if operating expenses exceed our expectations or cannot be adjusted accordingly, then our business, results of operations and financial condition will be materially and adversely affected. Because our strategy might include acquisitions of other businesses, acquisition expenses and any cash used to make these acquisitions will reduce our available cash. Our business will suffer if we are unable to raise additional equity funding. We continue to be dependent on our ability to raise money in the equity markets. There is no guarantee that we will continue to be successful in raising such funds. If we are unable to raise additional equity funds, we may be forced to discontinue or cease certain operations. We currently have sufficient operating capital to finance our operations beyond December 31, 2005. Our annual operating needs vary from year to year depending upon the amount of revenue generated through grants and licenses and the amount of projects we undertake, as well as the amount of resources we expend, in connection with acquisitions all of which may materially differ from year to year and may adversely affect our business. 25 Year ended December 31, 2005 $ 239,700 2006 255,400 2007 261,800 2008 133,200 2009 135,900 2010 22,700 ----------- Total $ 1,048,700 =========== Our stock price is, and we expect it to remain, volatile, which could limit investors' ability to sell stock at a profit. The volatile price of our stock makes it difficult for investors to predict the value of their investment, to sell shares at a profit at any given time, or to plan purchases and sales in advance. A variety of factors may affect the market price of our common stock. These include, but are not limited to: o publicity regarding actual or potential clinical results relating to products under development by our competitors or us; o delay or failure in initiating, completing or analyzing pre-clinical or clinical trials or the unsatisfactory design or results of these trials; o achievement or rejection of regulatory approvals by our competitors or us; o announcements of technological innovations or new commercial products by our competitors or us; o developments concerning proprietary rights, including patents; o developments concerning our collaborations; o regulatory developments in the United States and foreign countries; o economic or other crises and other external factors; o period-to-period fluctuations in our revenues and other results of operations; o changes in financial estimates by securities analysts; and o sales of our common stock. Additionally, because there is not a high volume of trading in our stock, any information about SIGA in the media may result in significant volatility in our stock price. We will not be able to control many of these factors, and we believe that period-to-period comparisons of our financial results will not necessarily be indicative of our future performance. In addition, the stock market in general, and the market for biotechnology companies in particular, has experienced extreme price and volume fluctuations that may have been unrelated or disproportionate to the operating performance of individual companies. These broad market and industry factors may seriously harm the market price of our common stock, regardless of our operating performance. We are in various stages of product development and there can be no assurance of successful commercialization. In general, our research and development programs are at an early stage of development. Our biological warfare defense products do not need human clinical trials for approval by the FDA. We will need to perform two animal models and provide safety data for a product to be approved. Our other products will be subject to the approval guidelines under FDA regulatory requirements which include a number of phases of testing in humans. The FDA has not approved any of our biopharmaceutical product candidates. Any drug candidates developed by us will require significant additional research and development efforts, including extensive pre-clinical and clinical testing and regulatory approval, prior to commercial sale. We cannot be sure our approach to drug discovery will be effective or will result in the development of any drug. We cannot expect that any drugs resulting from our research and development efforts will be commercially available for many years, if at all. We have limited experience in conducting pre-clinical testing and clinical trials. Even if we receive initially positive pre-clinical or clinical results, such results do not mean that similar results will be obtained in the later stages of drug development, such as additional pre-clinical testing or human clinical trials. All of our potential drug 26 candidates are prone to the risks of failure inherent in pharmaceutical product development, including the possibility that none of our drug candidates will or can: o be safe, non-toxic and effective; o otherwise meet applicable regulatory standards; o receive the necessary regulatory approvals; o develop into commercially viable drugs; o be manufactured or produced economically and on a large scale; o be successfully marketed; o be reimbursed by government and private insurers; and o achieve customer acceptance. In addition, third parties may preclude us from marketing our drugs through enforcement of their proprietary rights, that we are not aware of, or third parties may succeed in marketing equivalent or superior drug products. Our failure to develop safe, commercially viable drugs would have a material adverse effect on our business, financial condition and results of operations. Most of our immediately foreseeable future revenues are contingent upon grants from the United States government, and collaborative and license agreements and we may not achieve sufficient revenues from these agreements to attain profitability. Until and unless we successfully make a product, our ability to generate revenues will largely depend on our ability to enter into additional collaborative and license agreements with third parties and maintain the agreements we currently have in place. Substantially all of our revenues for the years ended December 31, 2004, 2003 and 2002, respectively, were derived from revenues related to grants, contracts and license agreements. We will receive little or no revenues under our collaborative agreements if our collaborators' research, development or marketing efforts are unsuccessful, or if our agreements are terminated early. Additionally, if we do not enter into new collaborative agreements, we will not receive future revenues from new sources. Our future revenue is substantially dependent on the continuing grant and contract work being performed for the NIH under two major grants which expire in September 2006 and the U.S. Army which expires at the end of December 2007. These agreements are for specific work to be performed under the agreements and could only be canceled by the other party thereto for non-performance by the other party thereto. Several factors will affect our future receipt of revenues from collaborative arrangements, including the amount of time and effort expended by our collaborators, the timing of the identification of useful drug targets and the timing of the discovery and development of drug candidates. Under our existing agreements, we may not earn significant milestone payments until our collaborators have advanced products into clinical testing, which may not occur for many years, if at all. We have material agreements with the following collaborators: o National Institutes of Health. Under our collaborative agreement with the NIH we have received SBIR Grants totaling approximately $12.1 million in 2004. The term of these grants expire in September 2006. We are paid as the work is performed and the agreement can be cancelled for non-performance. We also have an agreement whereby the NIH is required to conduct and pay for the clinical trials of our strep vaccine product through phase II human trials. The NIH can terminate the agreement on 60 days written notice. If terminated, we receive copies of all data, reports and other information related to the trials. If terminated, we would have to find another source of funds to continue to conduct the trials. We are current in all our obligations under our agreements. o The Rockefeller University. The term of our agreement with Rockefeller is for the duration of the patents and a number of pending patents. As we do not currently know when any patents pending or 27 future patents will expire, we cannot at this time definitively determine the term of this agreement. The agreement can be terminated earlier if we are in breach of the provisions of the agreement and do not cure the breach in the allowed cure period. We are current in all obligations under the contract. o Oregon State University ("OSU"). OSU is a signatory of our agreement with Rockefeller. The term of this agreement is for the duration of the patents and a number of pending patents. As we do not currently know when any patents pending or future patents will expire, we cannot at this time definitively determine the term of this agreement. The agreement can be terminated earlier if we are in breach of the provisions of the agreement and do not cure the breach in the allowed cure period. We are current in all obligations under the contract. We have also entered into a subcontract agreement with OSU for us to perform work under a grant OSU has from the NIH. The subcontract agreement was renewable annually and the current terms expired on August 31, 2003. Work on this agreement was completed in 2003. o Wyeth. Our license agreement expires on the earlier of June 30, 2007 or the last to expire patent that we have sub-licensed to them. Wyeth has the right to terminate the agreement on 90 days written notice. If terminated, all rights granted to Wyeth will revert to us, except for any compound identified by Wyeth prior to the date of termination and subject to the milestones and royalty obligations of the agreement. o Washington University. We have licensed certain technology from Washington under a non-exclusive license agreement. The term of our agreement with Washington is for the duration of the patents and a number of pending patents. As we do not currently know when any patents pending or future patents will expire, we cannot at this time definitively determine the term of this agreement. The agreement cannot be terminated unless we fail to pay our share of the joint patent costs for the technology licensed. We have currently met all our obligations under this agreement. o Regents of the University of California. We have licensed certain technology from Regents under an exclusive license agreement. We are required to pay minimum royalties under this agreement. This agreement is related to our agreement with Wyeth and expires at the same time as that agreement. It can be cancelled earlier if we default on our obligations or if Wyeth cancels its agreement with SIGA and we are not able to find a replacement for Wyeth. We have currently met all our obligations under this agreement. o U.S. Army Medical Research Acquisition Activity. In December 2002, we entered into a four years contract with the U.S. Army Medical Research Acquisition Activity (USAMRAA) to develop a drug to treat Smallpox. We are current in all our obligations under our agreement. o TransTech Pharma, Inc. Under our collaborative agreement with TransTech Pharma, TransTech Pharma is required to collaborate with us on the discovery, optimization and development of lead compounds to therapeutic agents. We and TransTech Pharma have agreed to share the costs of development and revenues generated from licensing and profits from any commercialized products sales. The agreement will be in effect until terminated by the parties or upon cessation of research or sales of all products developed under the agreement. We are current in all obligations under this agreement. The biopharmaceutical market in which we compete and will compete is highly competitive. The biopharmaceutical industry is characterized by rapid and significant technological change. Our success will depend on our ability to develop and apply our technologies in the design and development of our product candidates and to establish and maintain a market for our product candidates. There also are many companies, both public and private, including major pharmaceutical and chemical companies, specialized biotechnology firms, universities and other research institutions engaged in developing pharmaceutical and biotechnology products. Many of these companies have substantially greater financial, technical, research and development, and human resources than us. Competitors may develop products or other technologies that are more effective than any that are being 28 developed by us or may obtain FDA approval for products more rapidly than us. If we commence commercial sales of products, we still must compete in the manufacturing and marketing of such products, areas in which we have no experience. Many of these companies also have manufacturing facilities and established marketing capabilities that would enable such companies to market competing products through existing channels of distribution. Two companies with similar profiles are VaxGen, Inc., which is developing vaccines against anthrax, Smallpox and HIV/AIDS; and Avant Immunotherapeutics, Inc., which has vaccine programs for agents of biological warfare. Because we must obtain regulatory clearance to test and market our products in the United States, we cannot predict whether or when we will be permitted to commercialize our products. A pharmaceutical product cannot be marketed in the U.S. until it has completed rigorous pre-clinical testing and clinical trials and an extensive regulatory clearance process implemented by the FDA. Pharmaceutical products typically take many years to satisfy regulatory requirements and require the expenditure of substantial resources depending on the type, complexity and novelty of the product. Before commencing clinical trials in humans, we must submit and receive clearance from the FDA by means of an Investigational New Drug ("IND") application. Institutional review boards and the FDA oversee clinical trials and such trials: o must be conducted in conformance with the FDA's good laboratory practice regulations; o must meet requirements for institutional review board oversight; o must meet requirements for informed consent; o must meet requirements for good clinical and manufacturing practices; o are subject to continuing FDA oversight; o may require large numbers of test subjects; and o may be suspended by us or the FDA at any time if it is believed that the subjects participating in these trials are being exposed to unacceptable health risks or if the FDA finds deficiencies in the IND application or the conduct of these trials. Before receiving FDA clearance to market a product, we must demonstrate that the product is safe and effective on the patient population that will be treated. Data we obtain from preclinical and clinical activities are susceptible to varying interpretations that could delay, limit or prevent regulatory clearances. Additionally, we have limited experience in conducting and managing the clinical trials and manufacturing processes necessary to obtain regulatory clearance. If regulatory clearance of a product is granted, this clearance will be limited only to those states and conditions for which the product is demonstrated through clinical trials to be safe and efficacious. We cannot ensure that any compound developed by us, alone or with others, will prove to be safe and efficacious in clinical trials and will meet all of the applicable regulatory requirements needed to receive marketing clearance. If our technologies or those of our collaborators are alleged or found to infringe the patents or proprietary rights of others, we may be sued or have to license those rights from others on unfavorable terms. Our commercial success will depend significantly on our ability to operate without infringing the patents and proprietary rights of third parties. Our technologies, along with our licensors' and our collaborators' technologies, may infringe the patents or proprietary rights of others. If there is an adverse outcome in litigation or an interference to determine priority or other proceeding in a court or patent office, then we, or our collaborators and licensors, could be subjected to significant liabilities, required to license disputed rights from or to other parties and/or required to cease using a technology necessary to carry out research, development and commercialization. At present we are unaware of any or potential infringement claims against our patent portfolio. The costs to establish the validity of patents, to defend against patent infringement claims of others and to assert infringement claims against others can be expensive and time consuming, even if the outcome is favorable. 29 An outcome of any patent prosecution or litigation that is unfavorable to us or one of our licensors or collaborators may have a material adverse effect on us. We could incur substantial costs if we are required to defend ourselves in patent suits brought by third parties, if we participate in patent suits brought against or initiated by our licensors or collaborators or if we initiate such suits. We may not have sufficient funds or resources in the event of litigation. Additionally, we may not prevail in any such action. Any conflicts resulting from third-party patent applications and patents could significantly reduce the coverage of the patents owned, optioned by or licensed to us or our collaborators and limit our ability or that of our collaborators to obtain meaningful patent protection. If patents are issued to third parties that contain competitive or conflicting claims, we, our licensors or our collaborators may be legally prohibited from researching, developing or commercializing of potential products or be required to obtain licenses to these patents or to develop or obtain alternative technology. We, our licensors and/or our collaborators may be legally prohibited from using patented technology, may not be able to obtain any license to the patents and technologies of third parties on acceptable terms, if at all, or may not be able to obtain or develop alternative technologies. In addition, like many biopharmaceutical companies, we may from time to time hire scientific personnel formerly employed by other companies involved in one or more areas similar to the activities conducted by us. We and/or these individuals may be subject to allegations of trade secret misappropriation or other similar claims as a result of their prior affiliations. Our ability to compete may decrease if we do not adequately protect our intellectual property rights. Our commercial success will depend in part on our and our collaborators' ability to obtain and maintain patent protection for our proprietary technologies, drug targets and potential products and to effectively preserve our trade secrets. Because of the substantial length of time and expense associated with bringing potential products through the development and regulatory clearance processes to reach the marketplace, the pharmaceutical industry places considerable importance on obtaining patent and trade secret protection. The patent positions of pharmaceutical and biotechnology companies can be highly uncertain and involve complex legal and factual questions. No consistent policy regarding the breadth of claims allowed in biotechnology patents has emerged to date. Accordingly, we cannot predict the type and breadth of claims allowed in these patents. We have licensed the rights to eight issued U.S. patents and three issued European patents. These patents have varying lives and they are related to the technology licensed from Rockefeller University for the Strep and Gram-positive products. We have one additional patent application in the U.S. and one application in Europe relating to this technology. We are joint owner with Washington University of seven issued patents in the U.S. and one in Europe. In addition, there are four co-owned U.S. patent applications. These patents are for the technology used for the gram-negative product opportunities. We are also exclusive owner of one U.S. patent and three U.S. patent applications. One of these U.S. patent applications relates to our DegP product opportunities. We included a summary of out patent positions as of December 31, 2004 in Part I, Item 1 of this document. We also rely on copyright protection, trade secrets, know-how, continuing technological innovation and licensing opportunities. In an effort to maintain the confidentiality and ownership of trade secrets and proprietary information, we require our employees, consultants and some collaborators to execute confidentiality and invention assignment agreements upon commencement of a relationship with us. These agreements may not provide meaningful protection for our trade secrets, confidential information or inventions in the event of unauthorized use or disclosure of such information, and adequate remedies may not exist in the event of such unauthorized use or disclosure. We may have difficulty managing our growth. We expect to experience growth in the number of our employees and the scope of our operations. This growth has placed, and may continue to place, a significant strain on our management and operations. Our ability to manage this growth will depend upon our ability to broaden our management team and our ability to attract, hire and 30 retain skilled employees. Our success will also depend on the ability of our officers and key employees to continue to implement and improve our operational and other systems and to hire, train and manage our employees. Our activities involve hazardous materials and may subject us to environmental regulatory liabilities. Our biopharmaceutical research and development involves the controlled use of hazardous and radioactive materials and biological waste. We are subject to federal, state and local laws and regulations governing the use, manufacture, storage, handling and disposal of these materials and certain waste products. Although we believe that our safety procedures for handling and disposing of these materials comply with legally prescribed standards, the risk of accidental contamination or injury from these materials cannot be completely eliminated. In the event of an accident, we could be held liable for damages, and this liability could exceed our resources. The research and development activities of our company do not produce any unusual hazardous products. We do use small amounts of 32P, 35S and 3H, which are stored, used and disposed of in accordance with Nuclear Regulatory Commission ("NRC") regulations. We maintain liability insurance in the amount of approximately $5,000,000 and we believe this should be sufficient to cover any contingent losses. We believe that we are in compliance in all material respects with applicable environmental laws and regulations and currently do not expect to make material additional capital expenditures for environmental control facilities in the near term. However, we may have to incur significant costs to comply with current or future environmental laws and regulations. Our potential products may not be acceptable in the market or eligible for third party reimbursement resulting in a negative impact on our future financial results. Any products successfully developed by us or our collaborative partners may not achieve market acceptance. The antibiotic products which we are attempting to develop will compete with a number of well-established traditional antibiotic drugs manufactured and marketed by major pharmaceutical companies. The degree of market acceptance of any of our products will depend on a number of factors, including: o the establishment and demonstration in the medical community of the clinical efficacy and safety of such products, o the potential advantage of such products over existing treatment methods, and o reimbursement policies of government and third-party payors. Physicians, patients or the medical community in general may not accept or utilize any products that we or our collaborative partners may develop. Our ability to receive revenues and income with respect to drugs, if any, developed through the use of our technology will depend, in part, upon the extent to which reimbursement for the cost of such drugs will be available from third-party payors, such as government health administration authorities, private health care insurers, health maintenance organizations, pharmacy benefits management companies and other organizations. Third-party payors are increasingly disputing the prices charged for pharmaceutical products. If third-party reimbursement was not available or sufficient to allow profitable price levels to be maintained for drugs developed by us or our collaborative partners, it could adversely affect our business. If our products harm people, we may experience product liability claims that may not be covered by insurance. We face an inherent business risk of exposure to potential product liability claims in the event that drugs we develop are alleged to cause adverse effects on patients. Such risk exists for products being tested in human clinical trials, as well as products that receive regulatory approval for commercial sale. We may seek to obtain product liability insurance with respect to drugs we and/or or our collaborative partners develop. However, we may not be able to obtain such insurance. Even if such insurance is obtainable, it may not be available at a reasonable cost or in a sufficient amount to protect us against liability. 31 We may be required to perform additional clinical trials or change the labeling of our products if we or others identify side effects after our products are on the market, which could harm sales of the affected products. If we or others identify side effects after any of our products, if any, after they are on the market, or if manufacturing problems occur: o regulatory approval may be withdrawn; o reformulation of our products, additional clinical trials, changes in labeling of our products may be required; o changes to or re-approvals of our manufacturing facilities may be required; o sales of the affected products may drop significantly; o our reputation in the marketplace may suffer; and o lawsuits, including class action suits, may be brought against us. Any of the above occurrences could harm or prevent sales of the affected products or could increase the costs and expenses of commercializing and marketing these products. The manufacture of genetically engineered commensals is a time-consuming and complex process which may delay or prevent commercialization of our products, or may prevent our ability to produce an adequate volume for the successful commercialization of our products. Although our management believes that we have the ability to acquire or produce quantities of genetically engineered commensals sufficient to support our present needs for research and our projected needs for our initial clinical development programs, management believes that improvements in our manufacturing technology will be required to enable us to meet the volume and cost requirements needed for certain commercial applications of commensal products. Products based on commensals have never been manufactured on a commercial scale. The manufacture of all of our products will be subject to current GMP requirements prescribed by the FDA or other standards prescribed by the appropriate regulatory agency in the country of use. There can be no assurance that we will be able to manufacture products, or have products manufactured for us, in a timely fashion at acceptable quality and prices, that we or third party manufacturers can comply with GMP, or that we or third party manufacturers will be able to manufacture an adequate supply of product. Healthcare reform and controls on healthcare spending may limit the price we charge for any products and the amounts thereof that we can sell. The U.S. federal government and private insurers have considered ways to change, and have changed, the manner in which healthcare services are provided in the U.S. Potential approaches and changes in recent years include controls on healthcare spending and the creation of large purchasing groups. In the future, the U.S. government may institute further controls and limits on Medicare and Medicaid spending. These controls and limits might affect the payments we could collect from sales of any products. Uncertainties regarding future healthcare reform and private market practices could adversely affect our ability to sell any products profitably in the U.S. At present, we do not foresee any changes in FDA regulatory policies that would adversely affect our development programs. The future issuance of preferred stock may adversely affect the rights of the holders of our common stock. Our certificate of incorporation allows our Board of Directors to issue up to 10,000,000 shares of preferred stock and to fix the voting powers, designations, preferences, rights and qualifications, limitations or restrictions of 32 these shares without any further vote or action by the stockholders. The rights of the holders of common stock will be subject to, and could be adversely affected by, the rights of the holders of any preferred stock that we may issue in the future. The issuance of preferred stock, while providing desirable flexibility in connection with possible acquisitions and other corporate purposes, could have the effect of making it more difficult for a third party to acquire a majority of our outstanding voting stock, thereby delaying, deferring or preventing a change in control. Concentration of ownership of our capital stock could delay or prevent change of control. Our directors, executive officers and principal stockholders beneficially own a significant percentage of our common stock and preferred stock. They also have, through the exercise or conversion of certain securities, the right to acquire additional common stock. As a result, these stockholders, if acting together, have the ability to significantly influence the outcome of corporate actions requiring shareholder approval. Additionally, this concentration of ownership may have the effect of delaying or preventing a change in control of SIGA. At December 31, 2004, Directors, Officers and principal stockholders beneficially owned approximately 48.1% of our stock. Item 7A.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. Organization and Basis of Presentation Organization SIGA Technologies, Inc. ("SIGA" or the "Company") is engaged in the discovery, development and commercialization of vaccines, antibiotics, and novel anti-infectives for the prevention and treatment of infectious diseases, including products for use in defense against biological warfare agents. SIGA applies bacterial and viral genomics in the design and development of its products. The Company's product development programs emphasize the increasingly serious problem of drug resistant bacteria and emerging pathogens. Basis of presentation The accompanying financial statements have been prepared on a basis which assumes that the Company will continue as a going concern and which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. The Company has incurred cumulative net losses and expects to incur additional losses to perform further research and development activities. The Company does not have commercial products and has limited capital resources. Management's plans with regard to these matters include continued development of its products as well as seeking additional research support funds and financial arrangements. Although management continues to pursue these plans, there is no assurance that the Company will be successful in obtaining sufficient financing on terms acceptable to the Company. Management believes that its cash flows are sufficient to support its operations beyond December 31, 2005, and that sufficient cash flows will be available to meet the Company's business objectives. In the event that sufficient funds are not available, the Company will need to postpone or discontinue planned operations and projects. Continuance of the Company as a going concern is dependent upon, among other things, the success of the Company's research and development programs and the Company's ability to obtain adequate financing. The financial statements do not include any adjustments relating to the recoverability of the carrying amount of recorded assets and liabilities that might result from the outcome of these uncertainties. 2. Summary of Significant Accounting Policies Use of Estimates The financial statements and related disclosures are prepared in conformity with accounting principles generally accepted in the United States of America. Management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and revenue and expenses during the period reported. These estimates include the realization of deferred tax assets, useful lives and impairment of tangible and intangible assets, and the value of options and warrants granted by the Company. Estimates and assumptions are reviewed periodically and the effects of revisions are reflected in the financial statements in the period they are determined to be necessary. Actual results could differ from these estimates. Cash and cash equivalents Cash and cash equivalents consist of short term, highly liquid investments, with original maturities of less than three months when purchased and are stated at cost. Interest is accrued as earned. Property, Plant and Equipment Property, plant and equipment are stated at cost less accumulated depreciation. Depreciation is provided on the straight-line method over the estimated useful lives of the various asset classes. Estimated lives are 5 years for laboratory equipment; 3 years for computer equipment; 7 years for furniture and fixtures; and the life of the lease for leasehold improvements. Maintenance, repairs and minor replacements are charged to expense as incurred. Upon retirement or disposal of assets, the cost and related accumulated depreciation are removed from the Balance Sheet and any gain or loss is reflected in the Statement of Operations. Revenue Recognition The Company recognizes revenue from contract research and development and research payments in accordance with SEC Staff Accounting Bulletin No. 104, Revenue Recognition, ("SAB 104"). In accordance with SAB 104, revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed and 41 determinable, collectibility is reasonably assured, contractual obligations have been satisfied and title and risk of loss have been transferred to the customer. The Company recognizes revenue from non-refundable up-front payments, not tied to achieving a specific performance milestone, over the period which the Company is obligated to perform services or based on the percentage of costs incurred to date, estimated costs to complete and total expected contract revenue. Payments for development activities are recognized as revenue as earned, over the period of effort. Substantive at-risk milestone payments, which are based on achieving a specific performance milestone, are recognized as revenue when the milestone is achieved and the related payment is due, providing there is no future service obligation associated with that milestone. In situations where the Company receives payment in advance of the performance of services, such amounts are deferred and recognized as revenue as the related services are performed. For the years ended December 31, 2004, 2003 and 2002, revenues from National Institute of Health ("NIH") SBIR grants approximated 77%, 54% and 78%, respectively, of total revenues recognized by the Company. Accounts Receivable Accounts receivable are recorded net of provisions for doubtful accounts. An allowance for doubtful accounts is based on specific analysis of the receivables. At December 31, 2004, 2003 and 2002 the Company had no allowance for doubtful accounts. Research and development Research and development expenses include costs directly attributable to the conduct of research and development programs, including employees related costs, materials, supplies, depreciation on and maintenance of research equipment, the cost of services provided by outside contractors, and facility costs, such as rent, utilities, and general support services. All costs associated with research and development are expensed as incurred. Costs related to the acquisition of technology rights, for which development work is still in process, and that have no alternative future uses, are expensed as incurred. Goodwill Goodwill is recorded when the purchase price paid for an acquisition exceeds the estimated fair value of the net identified tangible and intangible assets acquired. The Company performs an annual review in the fourth quarter of each year, or more frequently if indicators of potential impairment exist, to determine if the carrying value of the recorded goodwill is impaired. Goodwill impairment is determined using a two-step approach in accordance with Statement of Financial Accounting Standards No. 142 "Goodwill and Other Intangible Assets" ("SFAS 142"). The impairment review process compares the fair value of the reporting unit in which goodwill resides to its carrying value. In 2004, the Company operated as one business and one reporting unit. Therefore, the goodwill impairment analysis was performed on the basis of the Company as a whole, using the market capitalization of the Company as an estimate of its fair value. The estimated fair values might produce significantly different results if other reasonable assumptions and estimates were to be used. Identified Intangible Assets Acquisition-related intangible assets include acquired technology, customer contracts, grants and covenants not to compete, and are amortized on a straight line basis over periods ranging from 3.5-4 years. In accordance with Statement of Financial Accounting Standards No. 144 "Accounting for the Impairment or Disposal of Long-Lived Assets" ("SFAS 144"), the Company performs a review of its identified intangible assets to determine if facts and circumstances exist which indicate that the useful life is shorter than originally estimated or that the carrying amount of assets may not be recoverable. If such facts and circumstances do exist, the Company assesses the recoverability of identified intangible assets by comparing the projected undiscounted net cash flows associated with the related asset or group of assets over their remaining lives against their respective carrying amounts. Impairment, if any, is based on the excess of the carrying amount over the fair value of those assets. Changes in events or circumstances that may affect long-lived assets include, but are not limited to, cancellations or terminations of research contracts or pending government grants (Note 4). 42 Income taxes Income taxes are accounted for under the asset and liability method prescribed by Statement of Financial Accounting Standards No. 109, "Accounting for Income Taxes." Deferred income taxes are recorded for temporary differences between financial statement carrying amounts and the tax basis of assets and liabilities. Deferred tax assets and liabilities reflect the tax rates expected to be in effect for the years in which the differences are expected to reverse. A valuation allowance is provided if it is more likely than not that some or all of the deferred tax asset will not be realized. Net loss per common share The Company computes, presents and discloses earnings per share in accordance with SFAS 128 "Earnings Per Share" ("EPS") which specifies the computation, presentation and disclosure requirements for earnings per share of entities with publicly held common stock or potential common stock. The statement defines two earnings per share calculations, basic and diluted. The objective of basic EPS is to measure the performance of an entity over the reporting period by dividing income (loss) by the weighted average shares outstanding. The objective of diluted EPS is consistent with that of basic EPS, that is to measure the performance of an entity over the reporting period, while giving effect to all dilutive potential common shares that were outstanding during the period. The calculation of diluted EPS is similar to basic EPS except the denominator is increased for the conversion of potential common shares. The Company incurred losses for the years ended December 31, 2004, 2003 and 2002 and as a result, certain equity instruments are excluded from the calculation of diluted loss per share. At December 31, 2004, 2003 and 2002, 68,038, 81,366 and 410,760 shares, respectively, of the Company's Series A convertible preferred stock have been excluded from the computation of diluted loss per share as they are anti-dilutive. At December 31, 2004, 2003 and 2002, outstanding options to purchase 9,762,061, 6,460,811 and 5,807,561 shares, respectively, of the Company's common stock with exercise prices ranging from $1.00 to $5.50 have been excluded from the computation of diluted loss per share as they are anti-dilutive. At December 31, 2004, 2003 and 2002, outstanding warrants to purchase 8,469,594, 6,329,616 and 4,675,144 shares, respectively, of the Company's common stock, with exercise prices ranging from $1.00 to $3.63 have been excluded from the computation of diluted loss per share as they are anti-dilutive. Fair value of financial instruments The carrying value of cash and cash equivalents, accounts payable and accrued expenses approximates fair value due to the relatively short maturity of these instruments. Concentration of credit risk The Company has cash in bank accounts that exceed the Federal Deposit Insurance Corporation insured limits. The Company has not experienced any losses on its cash accounts. No allowance has been provided for potential credit losses because management believes that any such losses would be minimal. Stock compensation The Company applies the recognition and measurement principles of Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB 25") and related interpretations in accounting for its stock-based compensation program. Accordingly, employees' and directors' related compensation expense is recognized only to the extent of the intrinsic value of the compensatory options or shares granted. 43 The following table illustrates the effect on net income (loss) available to common stockholders and earnings (loss) per share as if the Company had applied the fair value recognition provisions of SFAS No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123"), as amended by SFAS 148, "Accounting for Stock-Based Compensation - Transaction and Disclosure, an amendment to FASB Statement No. 123." The fair value of the options granted to employees during 2004, 2003 and 2002 ranged from $0.09 to $2.75 on the date of the respective grant using the Black-Scholes option-pricing model. The value of options granted in 2004, 2003 and 2002 was estimated at the date of grant using the following weighted average assumptions: Segment information The Company is managed and operated as one business. The entire business is managed by a single management team that reports to the chief executive officer. The Company does not operate separate lines of business or separate business entities with respect to any of its product candidates. Accordingly, the Company does not prepare discrete financial information with respect to separate product areas or by location and only has one reportable segment as defined by SFAS No. 131, "Disclosures about Segments of an Enterprise and Related Information". Recent accounting pronouncements In December 2004, the FASB issued SFAS No. 123R, "Share-Based Payment." SFAS No. 123R requires employee stock options and rights to purchase shares under stock participation plans to be accounted for under the fair value method, and eliminates the ability to account for these instruments under the intrinsic value method prescribed by APB Opinion No. 25, and allowed under the original provisions of SFAS No. 123. SFAS No. 123R requires the use of an option pricing model for estimating fair value, which is amortized to expense over the service periods. The requirements of SFAS No. 123R are effective for fiscal periods beginning after June 15, 2005. SFAS No. 123R allows for either prospective recognition of compensation expense or retrospective recognition, which may be back to the original issuance of SFAS No. 123 or only to interim periods in the year of adoption. The Company is currently evaluating these transition methods. In March 2004, the Emerging Issues Task Force issued EITF 03-06, "Participating Securities and the Two-Class Method under FASB Statement No. 128". This statement provides additional guidance on the calculation and disclosure requirements for earnings per share. The FASB concluded in EITF 03-06 that companies with multiple 44 Year Ended December 31, 2004 2003 2002 ------------ ------------ ------------ Net loss applicable to common shareholders, as reported ....

The adoption of this statement did not have an impact on the Company's financial statements presentation as the Company is in a loss position. 3. Business Acquisitions and Other Transactions Purchase of Intangible Assets In August 2004, the Company acquired certain government grants and two early stage antiviral programs, Smallpox and Arenavirus, targeting certain agenda of biological warfare for a purchase price of $1,000,000 in cash and 1,000,000 shares of the Company's common stock from ViroPharma Incorporated ("ViroPharma") (the "ViroPharma Transaction"). Each program is in the early stage of development and the Company expects both programs to be completed in or by 2006. The shares issued to ViroPharma were valued at the closing date price. The total purchase price of approximately $2.5 million was allocated to the acquired government grants ($1.9 million) and to purchased in-process research and development ($464,000 allocated to the Smallpox program and approximately $104,000 to the Arenavirus program) ("IPRD"). The grants are amortized over the contractual life of each grant or 2 years. The amount expensed as IPRD was attributed to technology that has not reached technological feasibility and has no alternate future use. The value allocated to IPRD was determined using the income approach that included an excess earnings analysis reflecting the appropriate costs of capital for the purchase. Estimates of future cash flows related to the IPRD were made for both the Smallpox and Arenavirus programs. The aggregate discount rate of approximately 55% utilized to discount the programs' cash flows were based on consideration of the Company's weighted average cost of capital as well as other factors, including the stage of completion and the uncertainty of technology advances for these programs. If the programs are not successful or completed in a timely manner, the Company's product pricing and growth rates may not be achieved and the Company may not realize the financial benefits expected from the programs. Business Acquisition On May 23, 2003, the Company acquired substantially all of the assets of Plexus Vaccine Inc., ("Plexus") and assumed certain liabilities in exchange for 1,950,000 shares of the Company's common stock and 190,950 of the Company's options and warrants at an exercise price of $1.62 per share. The results of operations of Plexus have been included in the Statement of Operations of the combined entity since May 23, 2003. In determining the non-cash purchase price of Plexus, the equity consideration has been calculated based on Emerging Issues Task Force ("EITF") No. 99-12, "Accounting for Formula Arrangements under EITF 95-19". For this calculation, the Company used the average market price for a few days before and after May 14, 2003, the announcement date. Based on EITF 99-12, the value of the common stock issued was approximately $3,409,000. The value attributed to the options and warrants exchanged was approximately $255,900. In addition, loans made to Plexus, payments made on behalf of Plexus prior to the asset purchase agreement and costs incurred for the transaction amounted to $406,030. The allocation of the total purchase price of $4,070,903 is as follows: In May 2004, the Company sold certain intangible assets originally acquired from Plexus, to Pecos Labs, Inc. ("Pecos"). See Note 4 "Intangible Assets". 45 Useful Life Fair Value --------------- -------------- Equipment, net 3 - 7 years $ 27,711 Liabilities assumed N/A (494,142) Acquired technology 10 years 2,191,000 Customer contract and grants 3 1/2 years 741,000 Covenant not to compete 3 1/2 years 707,000 Goodwill Indefinite 898,334 ----------- Purchase Price $ 4,070,903 =========== Selected Unaudited Pro Forma Financial Information The Company has prepared a condensed pro forma statement of operations in accordance with SFAS 141, for the years ended December 31, 2003 and 2002 as if Plexus were part of the Company as of January 1, 2003 and 2002, respectively. In the fourth quarter of 2003, a customer contract acquired with the acquisition of Plexus was cancelled.

Management determined that significant efforts and resources will be necessary to successfully continue the development efforts under these programs and decided to allocate the necessary resources to support its commitment. As a result, limited resources will be available for the development of future product candidates that utilize the technology acquired from Plexus in May 2003. These factors resulted in a significant reduction in forecasted revenues related to that technology and a reduction in the future remaining useful life, and triggered the related intangible asset impairment. The amount of impairment recorded by management in December 2004 was determined using the two-step process impairment review as required by SFAS 144. In the first step, management compared the projected undiscounted net cash flows associated with the technology acquired from Plexus over its remaining life against its carrying amount. Management determined that the carrying amount of the technology acquired from Plexus exceeded its projected undiscounted cash flows. In the second step, management estimated the fair value of the technology using the income method of valuation, which included the use of estimated discounted cash flows using a discount rate of 28.5%. Based on management's assessment, the Company recorded a non-cash impairment charge of approximately $1.5 million in December 2004, which was included as a component of the Company's operating loss. Transfer of Intangible Assets to Pecos Labs, Inc. In May 2004, the Company sold intangible assets from its immunological bioinformatics technology and certain non-core vaccine development assets to a privately-held company, Pecos Labs, Inc. ("Pecos") in exchange for 150,000 shares of Pecos common stock. In addition, concurrent with the asset transfer, the Company terminated its employment agreement with the President of the Company. The Company paid approximately $270,000 in severance to the President as well as accelerated vesting on 100,000 stock options that were due to vest in May 2004. No compensation charge was recorded as the exercise price of the options was above the fair value market price on the date of termination. In addition, the Company reduced the covenant not to compete with the President to one year from the date of termination. As a result of the Pecos transaction in the second quarter of 2004, the Company performed an impairment review of the intangible assets in accordance with SFAS 144. The impairment of intangible assets consists of $307,063 of impairments to unamortized intangible assets related to the grants transferred to Pecos and $303,000 of impairment to the unamortized covenant not to compete with the President of the Company due to the reduction of the covenant to one year from the date of termination. The Company is accounting for its investment in Pecos using the cost method under Accounting Principles Board Opinion No. 18, "The Equity Method of Accounting for Investments in Common Stock" based upon its 10% ownership of Pecos. The Company valued the 150,000 common shares at $0.10 per share based on an investment made at a concurrent time by an outside investor to Pecos at $0.10 per share. 5. Stockholders' Equity At December 31, 2004, the Company's authorized share capital consisted of 60,000,000 shares, of which 50,000,000 are designated common shares and 10,000,000 are designated preferred shares.

Stock option plan and warrants Amended and Restated 1996 Incentive and Non-Qualified Stock Option Plan In January 1996, the Company implemented its 1996 Incentive and Non-Qualified Stock Option Plan (the "Plan"). The Plan as amended provides for the granting of up to 10,000,000 shares of the Company's common stock to employees, consultants and outside directors of the Company. The exercise period for options granted under the Plan, except those granted to outside directors, is determined by a committee of the Board of Directors. Stock options granted to outside directors pursuant to the Plan must have an exercise price equal to or in excess of the fair market value of the Company's common stock at the date of grant.

Related Parties Directors The Company's Chairman of the Board of Directors is Vice Chairman and a director of MacAndrews & Forbes. During 2003 and January 2004, MacAndrews & Forbes, along with TransTech Pharma, invested $10.0 million in SIGA. Furthermore, two directors of the Company are also directors of TransTech Pharma. Additionally, a director of the Company, is a member of the Company's outside counsel. (See Note 5). Collaborative Research Agreements In October 2002, the Company entered into a collaborative research agreement with TransTech Pharma, a related party, for the discovery and treatment of human diseases. Under the terms of the agreement, TransTech Pharma and the Company have agreed to contribute each of their respective services and share equally in costs of specified research projects. In consideration of the services performed by TransTech Pharma and use of its proprietary technology, SIGA granted an exclusive, fully-paid, nontransferable, nonsublicenseable, limited license to use existing rights to patents and technologies. Both parties will share equally in the ownership of compounds and related intellectual property derived from such research efforts. In January 2004, TransTech Pharma invested $5.0 million in SIGA (See Note 5). 51 8. Property, Plant and Equipment Property, plant and equipment consisted of the following at December 31, 2004 and 2003: The Company has incurred losses since inception, which have generated net operating loss carryforwards of approximately $31,350,000 at December 31, 2004 for federal and state income tax purposes. These carryforwards are available to offset future taxable income and begin expiring in 2010 for federal income tax purposes. As a result of a previous change in stock ownership, the annual utilization of the net operating loss carryforwards is subject to limitation. The net operating loss carryforwards and temporary differences, arising primarily from deferred research and development expenses and differences in the treatment of intangible assets, result in a noncurrent deferred tax asset at December 31, 2004 and 2003 of approximately $16,500,000 and $13,030,000, respectively. In consideration of the Company's accumulated losses and the uncertainty of its ability to utilize this deferred tax asset in the future, the Company has recorded a valuation allowance of an equal amount on such date to fully offset the deferred tax asset. Following is a summary of changes in our valuation allowance for deferred tax assets as of and for the years ended December 31, 2004, 2003 and 2002 (in thousands): For the years ended December 31, 2004 and 2003, the Company's effective tax rate differs from the federal statutory rate principally due to net operating losses and other temporary differences for which no benefit was recorded, state taxes and other permanent differences. 10.

For the years ended December 31, 2004, 2003 and 2002, there was no stock compensation charge as the fair value of the underlying common stock was below the exercise price of the option. In June 2004, the Company entered into an amendment to its existing employment agreement with the Company's Chief Financial Officer. Pursuant to the amendment, the employment agreement is effective through December 31, 2005 and provides for an annual salary of $230,000 plus a one-time payment of $50,000 for the Chief Financial Officer's prior service as Acting Chief Executive Officer. An additional bonus not to exceed 25% of the Chief Financial Officer's salary may be awarded at the discretion of the Board of Directors. The agreement also provides for an option grant of 150,000 options to purchase common stock with an exercise price of $1.40, of which 75,000 vested upon signing and the remainder to vest on a prorata basis from January 1, 2005 through December 31, 2005.
