MECHANISMS TO PREVENT INFECTION [Photo] For a pathogen to infect a host, an interaction is required between its surface proteins and the host's mucosal tissue. SIGA uses two different methods to prevent serious infection. One is to develop mucosal vaccines, inducing antibodies at mucosal surfaces, blocking the ability of the pathogen to adhere. The second is to develop novel anti-infectives that will prevent surface proteins from being expressed. SIGA has major mucosal vaccine development programs targeting strep throat and periodontal diseases; gram positive vectors for STD vaccines--HIV, HSV and HPV; and new targets for the development of antibiotics.

THE COMPANY The Company is a development stage, biopharmaceutical company focused on the discovery, development and commercialization of vaccines, antibiotics and novel anti-infectives for serious infectious diseases. The Company's lead vaccine candidate is for the prevention of "strep throat." The Company is developing a technology for the mucosal delivery of its vaccines which may allow those 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. The Company's anti- infectives programs, aimed at the increasingly serious problem of drug resistance, are designed to block the ability of bacteria to attach to human tissue, the first step in the infection process. The Company does not expect to market any products for at least four years. VACCINE CANDIDATES The Company's lead vaccine candidate is for the prevention of group A streptococcal pharyngitis or "strep throat," a recurrent infection affecting between seven and 20 million children in the United States each year. Strep throat remains the most common childhood disease for which there is no vaccine available, and, if ineffectively treated, can progress to rheumatic fever. No vaccine has been developed because more than 100 different serotypes of group A streptococcus are known to cause the disease. In order to be effective, a vaccine would have to be based upon an antigen (a molecule that triggers an immune response) common to most of the important serotypes. The high incidence of the disease, the potentially serious consequences of inadequate treatment and the recent emergence of drug-tolerant types of group A streptococcus create an important medical need for an effective vaccine. The Company's proprietary antigen addresses the challenge of multiple serotypes in that this antigen is common to most types of the bacteria that cause strep throat, including types that have been associated with rheumatic fever. When a vaccine incorporating this antigen was orally administered to animals, it was shown to provide protection against multiple types of group A streptococcal infection. The Company's vaccine candidate for strep throat utilizes this antigen. The Company is collaborating with the National Institutes of Health and the University of Maryland Center for Vaccine Development on the clinical development of this vaccine candidate and expects to file an Investigational New Drug Application ("IND") with the United States Food and Drug Administration (the "FDA") in the fall of 1997. In addition to its strep throat vaccine, the Company is collaborating with Chiron Corporation ("Chiron") on research toward the development of vaccines against two sexually transmitted diseases and is testing a vaccine to prevent periodontal disease in a collaboration with The Research Foundation of State University of New York at Buffalo ("SUNY Buffalo"). 5 MUCOSAL VACCINE DELIVERY SYSTEM The Company is also developing a proprietary mucosal vaccine delivery system which is a component of the Company's vaccine candidates and which the Company intends to license to other vaccine developers. Mucosally-delivered vaccines are considered attractive because such vaccines may mobilize an immune response concentrated at the site of infection and because they may activate both a mucosal IgA antibody response as well as a systemic (IgG and T cell) response. The Company's mucosal vaccine delivery system utilizes commensal bacteria (harmless bacteria that live in and on the body) that have been genetically engineered to continually present disease-associated antigens that stimulate an immune response at the body's mucosal surfaces. In this manner, the bacteria may be able to prevent infection at the earliest possible stage. The Company believes that mucosal vaccines developed using its proprietary commensal delivery technology could provide a number of potential advantages over conventional vaccines, including: more complete protection; fewer side effects; the potential for single dose administration; non-injectable administration; the potential for combination vaccine delivery; and lower cost production. The Company's mucosal vaccine delivery technology is potentially applicable to any infectious disease that begins at a mucosal surface. ANTI-INFECTIVES AND ANTIBIOTICS THERAPY CANDIDATES The Company's 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. According to the Pharmaceutical Manufacturers Association, the United States and worldwide antibiotic markets are $7 billion and $22 billion, respectively. The Company's anti-infective 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 preventing the attachment of a bacterium to its target tissue. By preventing attachment, the bacteria should be readily cleared by the body's immune system. The Company's lead anti-infectives program is based on a novel target for antibiotic therapy. The Company's founding scientists have identified an enzyme, a selective protease, utilized 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. The Company's strategy is to develop protease inhibitors. The Company believes 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. The Company has entered into a collaborative research and license agreement with the Wyeth-Ayerst Laboratories Division of American Home Products Corporation ("Wyeth-Ayerst") to identify and develop protease inhibitors as novel antibiotics. Pursuant to the agreement, Wyeth-Ayerst is providing funding for a joint research and development program and is responsible for additional milestone payments. Under the terms of the agreement, the Company could receive up to $25 million in research and milestone payments for products developed from the licensed technologies. Wyeth-Ayerst has exclusive license rights in the field (as defined in the agreement) to any product resulting from this research and is required to make royalty payments based on sales of any product developed from the licensed technologies. See "Business--Collaborative Research and Licenses." The Company has entered into a letter of intent with MedImmune, Inc. ("MedImmune") regarding a technology transfer agreement pursuant to which the Company will acquire all of MedImmune's rights in gram-negative antibiotic targets, products, screens and services. The Company and MedImmune plan to collaborate in 6 the development of antibiotics against gram-negative pathogens. These bacteria utilize structures called pili to adhere to target tissue, and the Company plans to exploit the assembly and export of these essential infective structures as novel anti-infective targets. The Company and MedImmune contemplate that upon the execution of the technology transfer agreement, MedImmune will receive 335,530 shares of Common Stock (the "MedImmune Shares"). There can be no assurance that the Company will enter into a final agreement with MedImmune on the terms described above or at all. See "Risk Factors-- Dependence on Others; Collaborations." SURFACE PROTEIN EXPRESSION SYSTEM The Company is developing proprietary protein production systems based on its understanding of the mechanisms used by gram-positive bacteria to export and anchor surface proteins. Methods have been developed to engineer gram-positive bacteria to produce and secrete commercially useful proteins such as antigens or enzymes into the culture medium in a form requiring minimal purification. The Company believes that this technology provides a cost-effective alternative to E. coli, yeast and mammalian cell culture systems. COMPANY BACKGROUND The Company's technologies are licensed from The Rockefeller University ("Rockefeller"), Oregon State University ("Oregon State") and Emory University ("Emory"). The Company sponsors research and development activities in laboratories at Rockefeller, Emory, Oregon State and SUNY Buffalo, and does not maintain its own research and development facilities. See "Risk Factors-- Technologies Subject to Licenses" and "--Lack of Research and Development Facilities." The Company was incorporated in Delaware in December 1995. The Company's executive offices are located at 666 Third Avenue, New York, NY, 10017, and its telephone number is (212) 681-4970. 7 THE OFFERING Securities offered................................. 2,500,000 shares of Common Stock.

Common Stock should not be purchased by investors who cannot afford the loss of their entire investment. Prospective investors should carefully review and consider the following risks as well as the other information contained in this Prospectus. BUSINESS RISKS Limited Operating History; Accumulated Deficit; Operating Losses; Potential for Future Losses; Going Concern Explanatory Paragraph in Accountant's Report The Company, a development stage, biopharmaceutical company, was incorporated in December 1995 and accordingly has a limited operating history. As of June 30, 1997, the Company had an accumulated deficit of $3,582,187. The Company expects to incur substantial operating losses over the next several years and expects cumulative losses to increase as the Company's research and development and clinical efforts expand. In addition to increased research and development expenses, the Company also expects general and administrative expenses to increase due to increased staffing levels and increased costs, including patent and regulatory costs, necessary to support clinical trials, research and development and manufacturing. Revenues, if any, that the Company may receive in the next few years will be limited to payments under research or product development relationships that the Company may establish and payments under license agreements that the Company may enter into. There can be no assurance that the Company will be able to establish any such relationships, enter into any such license agreements or generate revenues. To achieve profitable operations, the Company, alone or with others, must successfully identify and develop pharmaceutical products, conduct clinical trials, obtain regulatory approvals and manufacture and market its pharmaceutical products or enter into license agreements with third parties on acceptable terms. The Company may never achieve significant revenues or profitable operations. The report of independent accountants on the Company's financial statements included herein contains an explanatory paragraph stating that the Company's financial statements have been prepared assuming that the Company will continue as a going concern while expressing substantial doubt as to the Company's ability to do so. The Company's ability to continue as a going concern is dependent on its ability to generate sufficient cash flow to meet its obligations as they become due. The Company has suffered operating losses since inception and expects to incur substantial additional operating losses in the development and commercialization of its technologies. These and other factors discussed in Note 1 to the financial statements raise substantial doubt about the Company's ability to continue as a going concern. See "Plan of Operation" and Financial Statements and Notes thereto. Early Stage of Development; Absence of Products; No Commercialization of Products Expected in Near Future The Company's product candidates are in an early stage of development. The Company has not completed the development of any products and, accordingly, has not received any regulatory approvals, commenced marketing activities or generated revenues from the sale of products. The Company's product candidates will require significant additional development, pre-clinical and clinical trials, regulatory approval and additional investment prior to commercialization. The Company does not expect to market any products for at least four years. In addition, the Company's product candidates are subject to the risks of failure inherent in the development of products based on innovative technologies. Accordingly, there can be no assurance that the Company's research and development efforts will be successful, that any of the Company's product candidates will prove to be safe, effective and non-toxic in clinical trials, that any commercially successful products will be developed, that the proprietary or patent rights of others will not preclude the Company from marketing its product candidates or that others will not develop competitive or superior products. As a result of the early stage of development of product candidates and the extensive testing and regulatory review process that such product candidates must undergo, the Company cannot predict with certainty when it will be able to market any of its products, if at all. The failure to develop safe, commercially viable products would have a material adverse effect on the Company's business, operating results and financial condition. 10 Uncertainty Due to Unproven Technology The Company's drug discovery approach faces technical issues which have not been resolved and requires the development of multiple novel technologies to create successful product candidates. While the Company has demonstrated that it has several novel bacterial targets, the Company has not proven that drugs which inhibit these targets will be safe and effective in human trials. Furthermore, there can be no assurance that the drug inhibition activity already demonstrated in primary screening will continue to be encouraging in further screening or drug discovery studies. The Company has not tested any product candidates in humans, and there can be no assurance that there will be clinical benefits associated with any such product candidates. Furthermore, there can be no assurance that the Company will successfully address these technological challenges or others that may arise in the course of product development. Any failure of the Company to anticipate or respond adequately to technological developments will have a material adverse effect on the Company's business, operating results and financial condition. There can be no assurance that the Company's technology will lead to the discovery and development of any viable product candidates in the future or that the Company will be able to utilize its drug discovery approach successfully. Future Capital Needs; Uncertainty Of Availability Of Additional Funding The Company will require substantial additional funds to conduct and sponsor research and development activities, to conduct pre-clinical and clinical testing, and to market its products. The Company's future capital requirements will depend on many factors, including continued scientific progress, progress with pre-clinical testing and clinical trials, the time and costs involved in obtaining regulatory approvals, the costs involved in filing, prosecuting and enforcing patent claims, competing technological and market developments, the ability of the Company to establish collaborative arrangements, effective commercialization activities and arrangements and the purchase or development of additional equipment and facilities. The Company expects the net proceeds of the Offering and the interest earned thereon will be sufficient to fund the Company's activities for at least 20 months. There can be no assurance, however, that changes in the Company's research and development plans or other events affecting the Company's operating expenses will not result in the utilization of such proceeds prior to that time. The Company has no other current sources of funding, apart from research payments and potential milestone payments from Wyeth-Ayerst. As a result, the Company will need to raise substantial additional funds before any of the Company's product candidates achieves regulatory approvals, if at all. The Company intends to seek such additional funding through collaborative arrangements and through public or private financings. There can be no assurance that additional financing will be available, or, if available, that such additional financing will be available on terms acceptable to the Company. In addition, for a period of 12 months (6 months in the case of any public offering under the Securities Act) after the date of this Prospectus, Sunrise's prior written consent is required if the Company seeks to raise additional funds through the issuance of equity. This may result in the Company being required to raise needed funding through the issuance of debt. If additional funds are raised by issuing debt, the Company will incur fixed payment obligations, which could delay the time, if any, when the Company may achieve positive cash flow. If adequate funds are not available, the Company may be required to delay, scale back or eliminate one or more of its principal product candidates or obtain funds through arrangements with collaborative partners or others that may require the Company to relinquish rights to certain of its technologies, product candidates or products that the Company would not otherwise relinquish. See "Use of Proceeds" and "Underwriting." Management's Broad Discretion in Application of Proceeds The Company intends to use approximately $1,000,000 (excluding accrued interest), or 9.4%, of the net proceeds of the Offering to repay outstanding indebtedness and the balance for the other purposes described under "Use of Proceeds." Although the Company's current estimate as to the amount of such net proceeds that will be used for each such other purpose is set forth under "Use of Proceeds," the Company reserves the right to change the amount of such net proceeds that will be used for any purpose to the extent that management 11 determines that such change is advisable. Accordingly, management of the Company will have broad discretion as to the application of the net proceeds of the Offering. See "Use of Proceeds" and "Plan of Operation." Technologies Subject to Licenses The Company and Rockefeller have entered into an exclusive worldwide license and research agreement whereby the Company has 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 technologies licensed by the Company pursuant to the agreement were developed in Dr. Fischetti's laboratory at Rockefeller, in Dr. Hruby's laboratory at Oregon State and at Emory. Researchers at Rockefeller and Oregon State collaborated, and are continuing to collaborate, on the development of the Company's strep throat vaccine candidate. Researchers at Rockefeller and Emory collaborated on the genetic identification of the antigen used in such vaccine candidate. Therefore, Oregon State and Emory joined in Rockefeller's license grant to the Company. The agreement generally requires the Company to pay royalties on sales of products developed from the licensed technologies and fees on revenues from sublicensees, where applicable, and the Company is responsible for certain milestone payments, of up to $225,000 per product, for each product developed from the licensed technologies. Pursuant to each of their contracts with their respective universities, Dr. Fischetti and Dr. Hruby will receive a percentage of royalties paid by the Company to Rockefeller and Oregon State pursuant to the license agreement. Dr. Fischetti will receive not more than 16.66% of any such royalties received by Rockefeller and Dr. Hruby will receive not more than 33.3% of any such royalties received by Oregon State. The Company is also responsible for certain costs incurred by Rockefeller for filing and prosecuting patent applications. At June 30, 1997, amounts payable to Rockefeller for patent application costs were $66,437. Should the Company default on its obligations to Rockefeller under the license agreement, its license would terminate, which would have a material adverse effect on the Company's operations and prospects. See "Business--Collaborative Research and Licenses." No Assurance of Successful Development of Product Candidates There can be no assurance that the Company's product candidates will be successfully developed into drugs that can be administered to humans or that any such drugs or therapies will prove to be safe and effective in clinical trials or cost-effective to manufacture. Further, any product candidates developed by the Company may prove to have adverse side effects. Dependence on Others; Collaborations The Company's strategy for the research, development and commercialization of its product candidates will require the Company to enter into various arrangements with corporate and academic collaborators, licensors, licensees and others, and may therefore be dependent upon the subsequent success of these outside parties in performing their responsibilities. The Company currently has a license and research agreement with Rockefeller, Emory and Oregon State; research support agreements with Emory, Oregon State and SUNY Buffalo; a consulting agreement with Dr. Vincent Fischetti; a clinical trials agreement with the National Institutes of Health; a collaborative research and license agreement with Wyeth-Ayerst; and a collaborative research agreement with Chiron. In addition, the Company has entered into a letter of intent with MedImmune regarding a technology transfer agreement pursuant to which the Company will acquire all of MedImmune's rights in gram-negative antibiotic targets, products, screens and services. There can be no assurance, however, that the Company will execute a final agreement with MedImmune on the terms described herein or at all. In addition, there can be no assurance that the Company will be able to establish other collaborative arrangements or license agreements that the Company deems necessary or acceptable to develop and commercialize its product candidates or that such collaborative arrangements or license agreements will be successful. Moreover, certain of the collaborative arrangements that the Company may enter into in the future may place responsibility for pre-clinical testing and clinical trials and for preparing and submitting applications for regulatory approval for product candidates on the collaborative partner. Should a collaborative partner fail to develop or commercialize successfully any product candidate to which the Company has rights, the Company's business may be adversely affected. See "Business--Collaborative Research and Licenses" and "Certain Transactions." 12 Lack of Manufacturing, Marketing or Sales Capabilities The Company has not invested in the development of commercial manufacturing, marketing, distribution or sales capabilities for any of its product candidates. The Company currently lacks the facilities to manufacture its product candidates in accordance with current Good Manufacturing Practices as prescribed by the FDA or to produce an adequate supply of compounds to meet future requirements for clinical trials. If the Company is unable to develop or contract for manufacturing capabilities on acceptable terms, the Company's ability to conduct pre-clinical and human clinical testing will be adversely affected, resulting in delays in the submission of products for regulatory approval and in the initiation of new development programs, which in turn could materially impair the Company's competitive position and the possibility of achieving profitability. The Company will need to hire additional personnel skilled in clinical testing, regulatory compliance, marketing and sales as it develops products with commercial potential. There can be no assurance that the Company will be able to hire such personnel, or establish third-party relationships to provide any or all of these resources. Dependence on Qualified Personnel and Consultants; Need for Additional Personnel David de Weese is the President and Chief Executive Officer of the Company. Dr. Vincent Fischetti is the principal founding scientist and Chief Scientific Advisor of the Company. Dr. Dennis Hruby is also a scientific founder and the Company's Vice President of Research. Drs. Hruby and Fischetti, along with Mr. de Weese, have primary responsibility for directing the Company's research efforts. Mr. de Weese, along with Dr. Joshua Schein and Judson Cooper, Executive Vice Presidents of the Company, have primary responsibility for directing the Company's strategic efforts. The Company's success is highly dependent on these individuals. The loss of the services of either Dr. Hruby or Dr. Fischetti or other personnel or consultants could have a material adverse effect on the Company's operations. Drs. Hruby and Fischetti, pursuant to each of their contracts with their respective universities, may spend only 20% of their time on non-university projects; however, the majority of the research being conducted by each of them is research sponsored by the Company and the Company has exclusive license rights to all inventions and discoveries resulting from this research. Overall, both Dr. Hruby and Dr. Fischetti spend more than 70% of their time on research sponsored by the Company and other Company business. See "Business-- Collaborative Research and Licenses." Mr. de Weese is the only full-time executive officer of the Company. Dr. Schein and Mr. Cooper, are also officers of Virologix Corporation and Callisto Pharmaceuticals, Inc., privately held, development stage, pharmaceutical companies, and devote substantial amounts of their time to the three companies on a substantially equal basis. Although the Company has entered into employment agreements with each of its key management and scientific employees and consulting agreements with its key outside scientific advisors, any of such persons may terminate his or her employment or consulting arrangement with the Company at any time on short notice. Accordingly, there can be no assurance that these employees and consultants will remain associated with the Company. The loss of the services of any of the Company's key personnel or consultants may impede the Company's ability to commercialize its product candidates. The Company maintains and is the named insured under a $1,000,000 life insurance policy on Dr. Fischetti and has an application pending for a $1,000,000 policy on Mr. de Weese. This policy is conditionally in force pending final underwriting, which is expected to be completed in September 1997. There can be no assurance that such insurance can be maintained or will be adequate to meet the Company's future needs. The Company's planned activities may require additional expertise in areas such as pre-clinical testing, clinical trial management, regulatory affairs, manufacturing and marketing. Such activities may require the addition of new personnel and the development of additional expertise by existing management personnel. The Company faces intense competition for such personnel from other companies, academic institutions, government entities and other organizations, and there can be no assurance that the Company will be successful in hiring or 13 retaining qualified personnel. The inability of the Company to develop additional expertise or to hire and retain such qualified personnel could have a material adverse effect on the Company's operations. Lack of Research and Development Facilities The Company does not maintain its own research and development facilities. The Company sponsors research and development activities at Dr. Fischetti's laboratory at Rockefeller and Dr. Hruby's laboratory at Oregon State, and at Emory and SUNY Buffalo. The Company's research is conducted by its employees and employees of the aforementioned universities. The Company's research and development efforts, therefore, are dependent upon its continued relationships with Dr. Fischetti, Dr. Hruby, Rockefeller, Oregon State, Emory and SUNY Buffalo. In the absence of such relationships, the Company would need to develop a new research and development arrangement with a third party, the availability of which there can be no assurance. If the Company is unable in the next 12 months to find an alternative source for bacteria used in its research which is currently being produced at Oregon State, the Company plans on leasing its own facility to produce such bacteria. The Company expects that the cost of securing a new source for such bacteria, whether obtained from a third party or produced at a facility leased by the Company, will not be materially greater than the fees currently paid to Oregon State allocable to the production of such bacteria. Any delay in finding suitable research and development facilities would postpone commercialization of the Company's products. See "Business--Human Resources and Facilities." Control by Management and Existing Stockholders Upon consummation of the Offering, the Company's management and existing holders of the Company's stock will, in the aggregate, own beneficially shares having approximately 57% of the total voting power of the Company's outstanding stock (without giving effect to the exercise of the Representatives' Warrants, options granted under the Plan, the de Weese Warrants, the Fischetti Warrants, the Directors/Advisors Warrants or the Bridge Warrants). As a result, these stockholders, acting together, would be able to effectively control most matters requiring approval by the stockholders of the Company, including the election of all of the directors. See "Principal Stockholders." Potential Conflicts of Interest Certain persons who are principal stockholders and executive officers of the Company are involved in various relationships that could result in conflicts between their interests and those of other stockholders of the Company. Dr. Schein and Mr. Cooper have employment arrangements with two other operating companies, which could force one or both of them to compromise or divert their business attention from the concerns of the Company from time to time. Additionally, Dr. Schein and Mr. Cooper are principals of CSO Ventures LLC ("CSO"), a privately held limited liability company which has a consulting agreement with the Company. Under the terms of Dr. Schein and Mr. Cooper's employment agreements with the Company, they are each entitled to the payment of certain fees in connection with any sale of the Company. This provision, together with lower prices paid by them for their shares of Common Stock relative to the prices paid by investors in this Offering, could result in a situation in which the purchase price paid in connection with any sale of the Company represents a gain on their investment in the Company while simultaneously representing a loss to investors in this Offering. See "Certain Transactions" and "Management." Possible Conflicts of Interest with Participants in Offering Nathan Low and Richard B. Stone are associated with Sunrise and Steven M. Oliveira is associated with Hampshire Securities Corporation. Sunrise and Hampshire Securities Corporation are members of the NASD participating in the distribution of the Securities in this Offering and Messrs. Low, Stone and Oliveira own an aggregate of approximately 1,055,367 shares of Common Stock, representing approximately 31.3% of the outstanding Common Stock prior to this Offering. In accordance with Rule 2720 of the Conduct Rules of the NASD, the Securities are being offered at an offering price no greater than that recommended by a qualified independent underwriter. As a result of such ownership, such participants may be deemed to have conflicts of interest with respect to the Offering and the public offering price of the Securities. See "Underwriting." 14 INDUSTRY RISKS No Assurance of Regulatory Approval; Need for Extensive Clinical Trials The production and marketing of the Company's principal product candidates, as well as certain of its research and development activities, are subject to regulation by governmental agencies in the United States and other countries. Any drug developed by the Company will be subject to a rigorous approval process pursuant to regulations administered by the FDA, comparable agencies in other countries and, to a lesser extent, state regulatory authorities. The approval process for any one of the Company's product candidates is likely to take several years or more depending upon the type, complexity and novelty of the pharmaceutical product and will involve significant expenditures by the Company for which additional financing will be required. The cost to the Company of conducting clinical trials for any potential product can vary dramatically based on a number of factors, including the order and timing of clinical indications pursued and the extent of development and financial support, if any, from collaborators. Because of the intense competition in the biopharmaceutical market and concern over the safety of participating in clinical trials, the Company may have difficulty obtaining sufficient patient populations or the support of clinicians to conduct its clinical trials as planned and may have to expend substantial additional funds to obtain access to such resources, or delay or modify its plans significantly. There can be no assurance that the Company will be able to obtain necessary clearances for clinical trials or approvals for the manufacturing or marketing of any of its product candidates, that the Company will have sufficient resources to complete the required regulatory review process or that the Company can survive the inability to obtain, or delays in obtaining, such approvals. Even if regulatory approvals are obtained, they may provide for significant limitations on the indicated uses for which a product may be marketed. As with all investigational products, additional government regulations may be promulgated requiring that additional research data be submitted that could delay marketing approval of any of the Company's product candidates. The subsequent discovery of previously unknown complications or the failure to comply with applicable regulatory requirements may result in restrictions on the marketing, or the withdrawal, of products or possible civil or criminal liabilities. In addition, the Company cannot predict whether any adverse government regulation might arise from future administrative actions. See "Business--Government Regulation." As part of the regulatory review process, the Company must sponsor and file, or obtain through others, an IND for each of its product candidates before the Company will be able to initiate the clinical trials necessary to generate safety and efficacy data for inclusion in an application for FDA marketing approval. The Company has not filed any INDs to date. Although the Company anticipates filing its first IND in 1997, the Company cannot predict with certainty when it might first submit any application for any product candidates for FDA or other regulatory review. There can be no assurance that clinical data from studies performed by the Company or others will be acceptable to the FDA or other regulatory agencies in support of any applications that may be submitted for regulatory approval and the FDA may, among other things, require the Company to collect additional data and conduct additional clinical studies prior to acceptance of any such applications. Uncertainty Regarding Patents and Proprietary Information The Company's ability to compete effectively will depend, in part, on its success in protecting its proprietary technology in the United States and abroad. The patent positions of biopharmaceutical firms generally are highly uncertain and involve complex legal and factual questions. No consistent policy has emerged regarding the breadth of claims covered in biopharmaceutical patents. As its research projects develop, the Company intends to file additional patent applications with the United States Patent and Trademark Office (the "PTO") and with corresponding foreign patent authorities. There can be no assurance that the PTO or any foreign jurisdictions will grant the Company's patent applications or that the Company will obtain any patents or other protection for which application for patent protection has been made. No assurance can be given that patents issued to or licensed by the Company will not be challenged, invalidated or circumvented, or that the rights granted thereunder will provide any competitive advantage. The Company will also rely on trade secrets, know-how and 15 continuing technological advancement in seeking to achieve a competitive position. No assurance can be given that the Company will be able to protect its rights to its unpatented trade secrets or that others will not independently develop substantially equivalent proprietary information and techniques or otherwise gain access to the Company's trade secrets. In addition to protecting its proprietary technology and trade secrets, the Company may be required to obtain additional licenses to patents or other proprietary rights from third parties. No assurance can be given that any additional licenses required under any patents or proprietary rights would be made available on acceptable terms, if at all. If the Company does not obtain required licenses, it could encounter delays in product development while it attempts to design around blocking patents, or it could find that the development, manufacture or sale of products requiring such licenses could be foreclosed. The Company could also incur substantial costs in defending any patent infringement suits or in asserting any patent rights, including those granted by third parties. The PTO could institute interference proceedings against the Company in connection with one or more of the Company's patents or patent applications, and such proceedings could result in an adverse decision as to priority of invention. The PTO or others could also institute reexamination proceedings with the PTO against the Company in connection with one or more of the Company's patents or patent applications and such proceedings could result in an adverse decision as to the validity or scope of any patents that the Company may obtain or have the right to use. See "Business--Patents and Proprietary Rights." Technological Change; Competition and Market Risk The biopharmaceutical industry is characterized by rapid and significant technological change. The Company's success will depend on its ability to develop and apply its technologies in the design and development of its product candidates and to establish and maintain a market for its 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 the Company. Competitors may develop products or other technologies that are more effective than any that are being developed by the Company or may obtain FDA approval for products more rapidly than the Company. If the Company commences commercial sales of products, it still must compete in the manufacturing and marketing of such products, areas in which the Company has 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. See "Business--Competition." Uncertainty of Pharmaceutical Pricing; Healthcare and Related Matters The levels of revenues and profitability of pharmaceutical companies may be affected by the continuing efforts of governmental and third party payors to contain or reduce the costs of healthcare through various means. For example, in certain foreign markets, pricing of prescription pharmaceuticals is subject to governmental control. In the United States, there have been, and the Company expects that there will continue to be, a number of federal and state proposals to implement similar government control. It is uncertain what legislative proposals will be adopted or what actions federal, state or private payors for healthcare goods and services may take in response to any healthcare reform or legislation. The Company cannot predict the effect that healthcare reforms may have on its business, and there can be no assurance that any such reforms will not have a material adverse effect on the Company. Further, to the extent that such proposals or reforms have a material adverse effect on the business, financial condition and profitability of other pharmaceutical companies that are prospective collaborators for certain of the Company's potential products, the Company's ability to commercialize its product candidates may be adversely affected. In addition, in both the United States and elsewhere, sales of prescription medical products are dependent in part on the availability of reimbursement to the consumer from third party payors, such as government and private insurance 16 plans. Third party payors can indirectly affect the pricing or the relative attractiveness of the Company's product candidates by regulating the maximum amount of reimbursement that they will provide for the Company's product candidates or by denying reimbursement. There can be no assurance that, if and when marketed, the Company's product candidates will be considered cost- effective by third party payors, that reimbursement will be available or, if available, that such third party payors' reimbursement policies will not adversely affect the Company's ability to sell its product candidates on a profitable basis. Limitations on, or failure to obtain, reimbursement for use of the Company's product candidates and changes in government and private third party payors' policies toward reimbursement could have a material adverse effect on the Company's ability to market its product candidates. Potential Product Liability and Availability of Insurance The Company's business exposes it to potential liability risks that are inherent in the testing, manufacturing and marketing of pharmaceutical products. The use of the Company's product candidates in clinical trials may expose the Company to product liability claims and possible adverse publicity. These risks will expand with respect to the Company's product candidates, if any, that receive regulatory approval for commercial sale. Product liability insurance for the biotechnology industry is generally expensive, if available at all. The Company does not have product liability insurance but intends to obtain such coverage if and when its product candidates are tested in clinical trials. There can be no assurance, however, that the Company will be able to obtain insurance coverage at acceptable costs or in a sufficient amount, if at all, or that a product liability claim would not adversely affect the Company's business, operating results or financial condition. OFFERING/INVESTMENT RISKS No Prior Public Market; Possible Volatility of Stock Price Prior to this Offering, there has been no public market for the Company's Common Stock. Accordingly, there can be no assurance that an active trading market will develop or be sustained subsequent to this Offering. The initial public offering price of the Common Stock has been determined by negotiations between the Company and the Underwriters and may not be indicative of the prices that may prevail in the public market. The Common Stock has been approved for quotation on the Nasdaq SmallCap Market ("Nasdaq"), but there is no assurance that the Company's future operating results will enable it to remain eligible for quotation on Nasdaq. If the Company is unable to satisfy such listing criteria in the future, the Common Stock may be delisted from trading on Nasdaq and consequently an investor could find it more difficult to dispose of, or to obtain accurate quotations as to the price of, the Common Stock. The stock market generally, and the biotechnology sector in particular, have experienced and are likely in the future to experience significant price and volume fluctuations which could adversely affect the market price of the Common Stock without regard to the significant fluctuations in response to variations in quarterly operating results, shortfalls in sales or earnings below analyst estimates, stock market conditions and other factors. There can be no assurance that the market price of the Common Stock will not experience significant fluctuations or decline below the initial public offering price. Sunrise's First Initial Public Offering Sunrise has not previously acted as an underwriter in connection with an initial public offering, although it has acted as a syndicate member, sole placement agent, co-placement agent, selected dealer or sole participating broker in more than 18 public and private offerings. Meyerson, however, has acted as an underwriter in connection with a number of initial public offerings. As part of its function, an underwriter establishes (in this case with the qualified independent underwriter) after negotiation with the Company the initial public offering price for the Common Stock. Sunrise's limited experience may adversely affect the pricing of the Offering and the liquidity of the Common Stock. Prospective purchasers of shares of Common Stock offered hereby should consider Sunrise's limited experience in evaluating an investment in the Common Stock. See "'Underwriting." No Market Making Activity by Sunrise Sunrise has indicated that it does not intend to act as a market maker in the Common Stock, which may adversely affect the price and liquidity of the Common Stock. 17 Shares Eligible for Future Sale Upon completion of this Offering, the Company will have outstanding 5,867,182 shares of Common Stock, without giving effect to (a) shares of Common Stock issuable upon exercise of (i) the Underwriters' Over-allotment Option, (ii) the Representatives' Warrants, (iii) options granted under the Plan, (iv) the de Weese Warrants, (v) the Fischetti Warrants, (vi) the Directors/Advisors Warrants or (vii) the Bridge Warrants or (b) the MedImmune Shares. (There can be no assurance that the Company will enter into a final agreement with MedImmune on the terms described herein or at all. See "Risk Factors--Dependence on Others; Collaborations.") Of such outstanding shares of Common Stock, all the shares to be sold by the Company in this Offering will be freely tradeable without restriction or further registration under the Securities Act, except for any shares held by "affiliates" of the Company within the meaning of the Securities Act which shares will be subject to the resale limitations of Rule 144 promulgated under the Securities Act. In addition, the estimated 100,000 shares of Common Stock issuable upon the exercise of the Bridge Warrants, all of which also are being registered under the Securities Act pursuant to the registration statement of which this Prospectus constitutes a part, will be freely transferable under the Securities Act, other than those shares held by affiliates of the Company. See "Plan of Operations--Bridge Financing." The remaining 3,367,182 shares (the "Restricted Shares") were issued by the Company in private transactions in reliance upon one or more exemptions contained in the Securities Act. 1,288,012 of the Restricted Shares were issued in connection with two private placement transactions completed in March and September 1996, respectively (the "Private Shares") and 2,079,170 of the Restricted Shares were issued to the founders of the Company in December 1995 (the "Founders' Shares"). The Restricted Shares are deemed to be "restricted securities" within the meaning of Rule 144 promulgated pursuant to the Securities Act and may be publicly sold only if registered under the Securities Act or sold pursuant to exemptions therefrom. Because the Founders' Shares and 1,038,008 of the Private Shares acquired in the March 1996 private placement will have been held for more than one year as of the date of this Prospectus, such shares will be eligible for public sale in accordance with the requirements of Rule 144, as amended. In addition, the remaining 250,004 of the Private Shares will be eligible for public sale in September 1997. However, certain holders of the Private Shares and the holders of the Founders' Shares have agreed with Sunrise not to sell or otherwise dispose of such shares for a period of six months and 24 months, respectively, after the date of the consummation of the Offering. See "Shares Eligible for Future Sale" and "Underwriting." Dilution; Equity Securities Sold Previously at Below Offering Price This Offering involves immediate dilution of $3.32 per share between the adjusted net tangible book value per share after the Offering and the per share public offering price of $5.00 attributable to the Common Stock. Investors in the Offering will contribute 84% of the aggregate consideration received for the aggregate number of shares of Common Stock outstanding after the Offering, but will only own 43% of the aggregate number of shares of Common Stock outstanding after the Offering. See "Dilution." Lack of Dividends The Company has not paid any dividends and does not contemplate paying dividends in the foreseeable future. It is currently anticipated that earnings, if any, will be retained by the Company to finance the development and expansion of the Company's business. See "Dividend Policy." Antitakeover Effect of Certificate of Incorporation The Company's Certificate of Incorporation authorizes the Board of Directors to determine the rights, preferences, privileges and restrictions of unissued series of preferred stock, $.0001 par value per share (the "Preferred Stock"), and to fix the number of shares of any series of Preferred Stock and the designation of any such series, without any vote or action by the Company's stockholders. Thus, the Board of Directors can authorize and issue up to 10,000,000 shares of Preferred Stock with voting or conversion rights that could adversely affect the voting or other rights of holders of the Company's Common Stock. In addition, the issuance of Preferred Stock may have the effect of delaying, deferring or preventing a change of control of the Company, since the terms of the Preferred Stock that might be issued could potentially prohibit the Company's 18 consummation of any merger, reorganization, sale of substantially all of its assets, liquidation or other extraordinary corporate transaction without the approval of the holders of the outstanding shares of the Common Stock. The Company, however, has no intention of adopting a stockholder rights plan ("poison pill") in the foreseeable future. See "Description of Securities-- Preferred Stock." Possible Delisting of Securities from Nasdaq SmallCap Market Following the Offering, the Company's Common Stock will meet the current Nasdaq listing requirements and will be initially included on Nasdaq. There can be no assurance, however, that the Company will meet the criteria for continued listing. Continued inclusion on Nasdaq generally requires that (i) the Company maintain at least $2,000,000 in total assets and $1,000,000 in capital and surplus, (ii) the minimum bid price of the Common Stock be $1.00 per share, (iii) there be at least 500,000 shares in the public float valued at $1,000,000 or more, (iv) the Common Stock have at least two active market makers, (v) the Common Stock be held by at least 300 holders and (vi) the Company meet certain corporate governance requirements. If the Company is unable to satisfy Nasdaq's listing standards, its securities may be delisted from Nasdaq. In such event, trading, if any, in the Common Stock would thereafter be conducted in the over-the-counter market on the so-called "pink sheets" or the NASD's "Electronic Bulletin Board." Consequently, the liquidity of the Company's securities could be impaired, not only in the number of securities which could be bought and sold, but also through delays in the timing of transactions, reduction in security analysts' and the news media's coverage of the Company and lower prices for the Company's securities than might otherwise be attained. Risks of Low-Priced Stock; "Penny Stock" Restrictions If the Company's securities were delisted from Nasdaq (See "--Possible Delisting of Securities from Nasdaq SmallCap Market"), they could become subject to Rule 15g-9 under the Exchange Act, which imposes additional sales practice requirements on broker-dealers which sell such securities to persons other than established customers and "accredited investors" (generally, individuals with net worths in excess of $1,000,000 or annual incomes exceeding $200,000, or $300,000 together with their spouses). For transactions covered by this rule, a broker-dealer must make a special suitability determination for the purchaser and have received the purchaser's written consent to the transaction prior to sale. Consequently, such rule may adversely affect the ability of broker-dealers to sell the Company's securities and may adversely affect the ability of purchasers in the Offering to sell in the secondary market any of the securities acquired hereby. Commission regulations define a "penny stock" to be any non-Nasdaq equity security that has a market price (as therein defined) of less than $5.00 per share or with an exercise price of less than $5.00 per share, subject to certain exceptions. For any transaction involving a penny stock, unless exempt, the rules require delivery, prior to any transaction in a penny stock, of a disclosure schedule prepared by the Commission relating to the penny stock market. Disclosure is also required to be made about commissions payable to both the broker-dealer and the registered representative and current quotations for the securities. Finally, monthly statements are required to be sent disclosing recent price information for the penny stock held in the account and information on the limited market in penny stocks. The foregoing required penny stock restrictions will not apply to the Company's securities if such securities are listed on Nasdaq and have certain price and volume information provided on a current and continuing basis or meet certain minimum net tangible assets or average revenue criteria. There can be no assurance that the Company's securities will qualify for exemption from these restrictions. In any event, even if the Company's securities were exempt from such restrictions, it would remain subject to Section 15(b)(6) of the Exchange Act, which gives the Commission the authority to prohibit any person that is engaged in unlawful conduct while participating in a distribution of a penny stock from associating with a broker-dealer or participating in a distribution of a penny stock, if the Commission finds that such a restriction would be in the public interest. If the Company's securities were subject to the rules on penny stocks, the market liquidity for the Company's securities could be severely adversely affected. 19 USE OF PROCEEDS The net proceeds to the Company from the sale of the shares of Common Stock offered hereby are estimated to be $10,625,000 ($12,271,250 if the Underwriters' Over-allotment Option is exercised in full) after deducting the underwriting discount and estimated offering expenses payable by the Company. The Company expects to use the net proceeds as follows:
APPROXIMATE APPROXIMATE PERCENTAGE APPLICATION OF PROCEEDS DOLLAR AMOUNT OF NET PROCEEDS - ----------------------- ------------- --------------- Research and development(1)..................... $ 3,750,000 35.3% General and administrative (2).................. 3,625,000 34.1 Repayment of Bridge Notes and accrued interest thereon(3)..................................... 1,033,333 9.7 Working capital................................. 2,216,667 20.9 ----------- ----- TOTAL......................................... $10,625,000 100.0% =========== =====
- -------- (1) Includes research support payments, salaries and related expenses for the Company's principal scientists and other employees currently hired or to be hired in connection with the Company's research and development activities, consulting fees for the Company's scientific consultants and advisors, patent expenses and other research and development related expenses. (2) Includes salaries and related expenses for the Company's officers and staff, consulting fees for the Company's consultants, legal and accounting expenses and other general and administrative expenses. (3) Represents the repayment of the outstanding principal amount of $1,000,000 plus estimated accrued interest thereon at the rate of 10% per annum as of June 30, 1997, on indebtedness incurred in the Bridge Financing. The proceeds of the Bridge Financing, in the amount of $1,000,000, were used for research and development, working capital and other general corporate purposes. If the Underwriters' Over-allotment Option is exercised in full, the Company will realize additional net proceeds of approximately $1,646,250, which amount will be added to the Company's working capital. The Company anticipates, based on currently proposed plans and assumptions relating to its operations, that the proceeds of this Offering will be sufficient to satisfy the Company's contemplated cash requirements for at least 20 months following the consummation of the Offering. In the event the Company's plans change or its assumptions change or prove to be inaccurate or the proceeds of the Offering prove to be insufficient to fund operations (due to unanticipated expenses, delays, problems or otherwise), the Company could be required to seek additional financing sooner than currently anticipated. The Company has no current arrangements with respect to, or sources of, additional financing, apart from research payments and potential milestone payments from Wyeth-Ayerst and there can be no assurance that additional financing will be available to the Company when needed on commercially reasonable terms or at all. Any inability to obtain additional financing when needed would have a material adverse effect on the Company, including possibly requiring the Company to significantly curtail or cease its operations. Until required for operations, the Company's policy is to invest its cash reserves in bank deposits, certificates of deposit, commercial paper, corporate notes, U.S. government instruments and other investment-grade quality instruments. 20 CAPITALIZATION The following table sets forth as of June 30, 1997 (i) the actual capitalization of the Company; and (ii) the pro forma capitalization of the Company as adjusted to give effect to the receipt and anticipated use of the estimated net proceeds of this Offering. This table should be read in conjunction with the Company's Financial Statements and Notes thereto, "Selected Financial Data" and "Plan of Operation" included elsewhere in this Prospectus.

RESULTS OF OPERATIONS The Company is a development stage, biopharmaceutical company. Since its inception in December 1995, the Company's efforts have been principally devoted to research and development, securing patent protection and raising capital. From inception through June 30, 1997, the Company has sustained cumulative losses of $3,582,187, including non-cash charges in the amount of $396,274 for stock option and warrant compensation expense. These losses have resulted primarily from expenditures incurred in connection with research and development, patent preparation and prosecution and general and administrative activities. From inception through June 30, 1997, research and development expenses amounted to $1,094,873, patent preparation and prosecution expenses amounted to $502,680 and general and administrative expenses amounted to $1,468,939. The Company expects to continue to incur substantial research and development costs in the future resulting from ongoing research and development programs, manufacturing of products for use in clinical trials and pre-clinical and clinical testing of the Company's products. The Company also expects that general and administrative costs, including patent and regulatory costs, necessary to support clinical trials, research and development, manufacturing and the creation of a marketing and sales organization, if warranted, will increase in the future. Accordingly, the Company expects to incur increasing operating losses for the foreseeable future. There can be no assurance that the Company will ever achieve profitable operations. To date, the Company has not marketed, or generated revenues from the commercialization of, any products. The Company's current product candidates are not expected to be commercially available for several years. General and administrative expenses from inception through June 30, 1997, were $1,468,939, primarily due to personnel costs and associated operating costs. The Company anticipates that general and administrative expenses will increase substantially during the next 12 months as the Company increases its staffing levels. Research and development expenditures consist primarily of payments for sponsored research, payments to its scientific consultants and the salaries of its research staff. Research and development expenses from inception through June 30, 1997 were $1,094,873. As of June 30, 1997, the Company had made advance payments of $211,458 for research support to Rockefeller for the period ending January 31, 1998. The Company has research support agreements with both Emory and Oregon State pursuant to which the Company is obligated to fund research through January 31, 1998 in the aggregate annual amount of $183,320. The Company anticipates that its research and development expenses will increase during the next 12 months as the Company continues to fund research programs and pre-clinical and clinical testing for its product candidates and technologies under development. See "--Product Research and Development Plan." From inception through June 30, 1997, the Company recorded non-cash compensation expense in the amount of $396,274 related to the issuance of compensatory stock options and warrants to the President of the Company and the consultant who serves as the Company's Chief Scientific Advisor. The warrants issued to the consultant were to compensate him for his efforts in introducing the Company to potential collaborative partners. LIQUIDITY AND CAPITAL RESOURCES 1996 Private Placement Transactions In March 1996, the Company completed a private placement transaction in which it sold 1,038,008 shares of Common Stock for an aggregate gross consideration of $1,557,000. In September 1996, the Company completed a private placement transaction in which it sold 250,004 shares of Common Stock for an aggregate gross consideration of $750,000. 25 Bridge Financing On February 28, 1997, the Company completed the Bridge Financing pursuant to which the Company issued Bridge Notes in the aggregate principal amount of $1,000,000 and Bridge Warrants to purchase an estimated 100,000 shares in aggregate of the Company's Common Stock (the actual number of shares will be determined by dividing one-half the principal of the Bridge Notes ($500,000) by the initial offering price per share) at an exercise price equal to the initial offering price per share. In the event an initial public offering of the Common Stock is not completed prior to the maturity date of the Bridge Notes, the holders of the Bridge Notes will receive Bridge Warrants to purchase an aggregate of 100,000 shares of Common Stock at an exercise price of $5.00 per share. The Bridge Notes bear interest at the rate of 10% per annum and are due on the earlier of six months subsequent to the date of issuance or the consummation of the Offering. As of August 28, 1997, the maturity date of Bridge Notes in the principal amount of $1,000,000, which had maturity dates of July and August 1997 had been extended to the earlier of October 1, 1997 or completion of the Offering. The Bridge Warrants, which are exercisable from the first anniversary of the date of the consummation of the Offering (or February 28, 1998 if the Offering is not consummated) until the fifth anniversary of the date of the consummation of the Offering (or February 28, 2002 if the Offering is not consummated), were issued to the Bridge Investors because the interest rate on the Bridge Notes did not provide the Bridge Investors with a sufficient rate of return given the risks associated with their investment in the Bridge Notes. None of the Bridge Investors are affiliates of the Company. The Bridge Investors have also agreed with the Company not to sell or otherwise dispose of the Bridge Warrants for a period of 12 months after the date of the consummation of the Offering. The Company intends to use a portion of the proceeds of the Offering to repay the Bridge Notes and the interest accrued thereon and will recognize an expense upon completion of the Offering relating to the unamortized portion of the debt discount associated with the Bridge Financing which amounted to $44,333 at June 30, 1997. Collaborative Research and License Agreement In July 1997, the Company entered into a collaborative research and license agreement with Wyeth-Ayerst. Under the terms of the agreement, the Company has granted Wyeth-Ayerst an exclusive worldwide license to develop, make, use and sell products derived from specified technologies. The agreement requires Wyeth-Ayerst to sponsor further research by the Company for the development of the licensed technologies for a period of two years from the effective date of the agreement, in return for payments to the Company totaling $1,200,000. An initial sponsored research payment in the amount of $300,000 was received by the Company within 30 days of the execution of the agreement. The remaining sponsored research payments are payable in equal quarterly installments over the two years. In consideration of the license grant, the Company is entitled to receive royalties equal to specified percentages of net sales of products incorporating the licensed technologies. The royalty percentages increase as certain cumulative and annual net sales amounts are attained. The Company could receive milestone payments, up to $13,750,000 for the initial product and up to $3,250,000 for the second product developed from a single compound derived from the licensed technologies. The Company could also receive, under certain circumstances, additional milestone payments, for an additional compound, as defined in the agreement, developed from the licensed technologies. Such milestone payments are contingent upon the Company meeting the milestones set forth in the agreement, and, accordingly, if the Company is unable to meet such milestones, the Company will not receive such milestone payments. Current Resources The Company anticipates that its current resources, together with the net proceeds of the Offering, will be sufficient to finance the Company's currently anticipated needs for operating and capital expenditures for at least 20 months from the consummation of this Offering. In addition, the Company will attempt to generate additional working capital through a combination of collaborative agreements, strategic alliances and equity and debt financings. However, no assurance can be provided that additional capital will be obtained through these sources. In addition, for a period of 12 months (6 months in the case of any public offering under the Securities Act) after the date of this Prospectus, Sunrise's prior written consent is required if the Company seeks to raise 26 additional funds through the issuance of equity. If the Company is not able to obtain continued financing the Company may cease operation and purchasers of the Common Stock will, in all likelihood, lose their entire investment. See "Underwriting." The Company's working capital and capital requirements will depend upon numerous factors, including progress of the Company's research and development programs; pre-clinical and clinical testing; timing and cost of obtaining regulatory approvals; levels of resources that the Company devotes to the development of manufacturing and marketing capabilities; technological advances; status of competitors; and ability of the Company to establish collaborative arrangements with other organizations. Until required for operations, the Company's policy is to invest its cash reserves in bank deposits, certificates of deposit, commercial paper, corporate notes, U.S. government instruments and other investment-grade quality instruments. At June 30, 1997, the Company had $129,913 in cash and cash equivalents, and a working capital deficit of $964,461. In accordance with the terms of the Bridge Notes, the Company will utilize proceeds of approximately $1,000,000 upon completion of the Offering to repay the principal of, and accrued interest through consummation of the Offering on, the Bridge Notes. See "Use of Proceeds" and Note 9 of Notes to Financial Statements. PRODUCT RESEARCH AND DEVELOPMENT PLAN The Company's plan of operation for the 12 months following completion of this Offering will consist primarily of research and development and related activities including: . formulation and further pre-clinical development of the Company's vaccine candidate for strep throat, and if successful, the initiation of clinical trials. See "Business--The Company's Product Candidates and Research and Discovery Programs--Mucosal Vaccines." . further development of the Company's anti-infectives programs aimed at blocking the function or expression of certain bacterial surface proteins. See "Business--The Company's Product Candidates and Research and Discovery Programs--Anti-Infectives." . continuing the funding of the research on mucosal vaccine delivery systems, mucosal vaccine candidates and novel anti-infectives currently being conducted at Rockefeller, Oregon State, Emory and SUNY Buffalo. See "Business--Collaborative Research and Licenses." . continuing the prosecution and filing of patent applications. See "Business--Patents and Proprietary Rights." . hiring additional employees, including filling senior positions in the areas of finance, product development and regulatory and clinical affairs. The actual research and development and related activities of the Company may vary significantly from current plans depending on numerous factors, including changes in the costs of such activities from current estimates, the results of the Company's research and development programs, the results of clinical studies, the timing of regulatory submissions, technological advances, determinations as to commercial potential and the status of competitive products. The focus and direction of the Company's operations will also be dependent upon the establishment of collaborative arrangements with other companies, and other factors. 27 BUSINESS The Company is a development stage, biopharmaceutical company focused on the discovery, development and commercialization of vaccines, antibiotics and novel anti-infectives for serious infectious diseases. The Company's lead vaccine candidate is for the prevention of "strep throat." The Company is developing a technology for the mucosal delivery of its vaccines which may allow those 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. The Company's anti-infectives programs, aimed at the increasingly serious problem of drug resistance, are designed to block the ability of bacteria to attach to human tissue, the first step in the infection process. SUMMARY Vaccine Candidates The Company's lead vaccine candidate is for the prevention of group A streptococcal pharyngitis or "strep throat," a recurrent infection affecting between seven and 20 million children in the United States each year. Strep throat remains the most common childhood disease for which there is no vaccine available, and, if ineffectively treated, can progress to rheumatic fever. No vaccine has been developed because more than 100 different serotypes of group A streptococcus are known to causes the disease. In order to be effective, a vaccine would have to be based upon an antigen (a molecule that triggers an immune response) common to most of the important serotypes. The high incidence of the disease, the potentially serious consequences of inadequate treatment and the recent emergence of drug-tolerant types of group A streptococcus create an important medical need for an effective vaccine. The Company's proprietary antigen addresses the challenge of multiple serotypes in that this antigen is common to most types of the bacteria that cause strep throat, including types that have been associated with rheumatic fever. When a vaccine incorporating this antigen was orally administered to animals, it was shown to provide protection against multiple types of group A streptococcal infection. The Company's vaccine candidate for strep throat utilizes this antigen. The Company is collaborating with the National Institutes of Health and the University of Maryland Center for Vaccine Development on the clinical development of this vaccine candidate and expects to file an IND with the FDA in the fall of 1997. In addition to its strep throat vaccine, the Company is also collaborating with Chiron on research toward the development of vaccines against two sexually transmitted diseases and is testing a vaccine to prevent periodontal disease in a collaboration with SUNY Buffalo. Mucosal Vaccine Delivery System The Company is also developing a proprietary mucosal vaccine delivery system which is a component of the Company's vaccine candidates and which the Company intends to license to other vaccine developers. Mucosally-delivered vaccines are considered attractive because such vaccines may mobilize an immune response concentrated at the site of infection and because they may activate both a mucosal IgA antibody response as well as a systemic (IgG and T cell) response. The Company's mucosal vaccine delivery system utilizes commensal bacteria (harmless bacteria that live in and on the body) that have been genetically engineered to continually present disease-associated antigens which stimulate an immune response at the body's mucosal surfaces thereby preventing infection at the earliest possible stage. The Company believes that mucosal vaccines developed using its proprietary commensal delivery technology could provide a number of potential advantages over conventional vaccines, including: more complete protection; fewer side effects; the potential for single dose administration; non-injectable administration; the potential for combination vaccine delivery; and lower cost production. The Company's mucosal vaccine delivery technology is potentially applicable to any infectious disease that begins at a mucosal surface. 28 Anti-Infectives and Antibiotics Therapy Candidates The Company's 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. According to the Pharmaceutical Manufacturer's Association, the United States and worldwide antibiotic markets are $7 billion and $22 billion, respectively. The Company's 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. By preventing attachment, the bacteria would be readily cleared by the body's immune system. The Company's lead anti-infectives program is based on a novel target for antibiotic therapy. The Company's founding scientists have identified an enzyme, a selective protease, utilized 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. The Company's strategy is to develop protease inhibitors. The Company believes protease inhibitors will have wide applicability to gram-positive bacteria in general, including antibiotic resistant staphlyococcus and a broad range of serious infectious diseases including meningitis and respiratory tract infections. The Company has entered into a collaborative research and license agreement with Wyeth-Ayerst to identify and develop protease inhibitors as novel antibiotics. The Company has entered into a letter of intent with MedImmune regarding a technology transfer agreement pursuant to which the Company will acquire all of MedImmune's rights in gram-negative antibiotic targets, products, screens and services. The Company and MedImmune plan to collaborate in the development of antibiotics against gram-negative pathogens. These bacteria utilize structures called pili to adhere to target tissue, and the Company plans to exploit the assembly and export of these essential infective structures as novel anti-infective targets. There can be no assurance that the Company will enter into a final agreement with MedImmune on the terms described herein or at all. See "Risk Factors--Dependence on Others; Collaborations." SURFACE PROTEIN EXPRESSION SYSTEM The Company is developing proprietary protein production systems based on its understanding of the mechanisms used by gram-positive bacteria to export and anchor surface proteins. Methods have been developed to engineer gram- positive bacteria to produce and secrete commercially useful proteins such as antigens or enzymes into the culture medium in a form requiring minimal purification. The Company believes that this technology provides a cost- effective alternative to E. coli, yeast and mammalian cell culture systems. BACKGROUND Infectious Diseases Infectious diseases are the leading cause of death in the world. For most of the twentieth century, the incidence of infectious disease has decreased dramatically due to the use of antibiotics and the development of effective vaccines to prevent many common diseases. In recent years, however, this trend has reversed with the emergence of many new infectious diseases or the re- emergence or increased incidence of known infectious diseases worldwide, a public health issue which has become "a threat to global health and security." There are many reasons for this emergence, including: (i) the intrusion of humans into formerly unpopulated or isolated populations has provided exposure to organisms previously unknown (e.g. Lyme disease, hantavirus, Ebola virus); (ii) the spread of disease-causing organisms has increased due to the ease of worldwide transportation; (iii) changes in human behavior, such as increased sexual activity and intravenous drug abuse, have contributed to the spread of diseases like human immunodeficiency virus ("HIV"), hepatitis, and chlamydia; (iv) the 29 widespread use of day care facilities has exposed a larger number of children to infectious diseases and, as a result, their families; (v) the use of immunosuppressive drugs, particularly for cancer treatment, has rendered susceptible an ever growing number of people subject to infectious diseases which in otherwise healthy individuals would be benign; (vi) past complacency of public health officials has resulted in lowered surveillance of and reduced prevention programs for infectious diseases leading to an inability to react quickly to newly arising infectious threats; and (vii) increased antibiotic resistance has resulted in a major threat from organisms which were effectively and easily treated in the past. As a result of these and other factors, the Centers for Disease Control and Prevention has estimated that between 1980 and 1992, in the United States, the mortality rate due to infectious diseases rose by 58%. Alarmingly, the age group most affected, ages 25 to 44 years, has experienced over a six-fold increase in infectious disease-related deaths during this period. Due to this increase, infectious diseases are now the third leading cause of death in the United States, following only cardiovascular and cancer-related deaths. The financial burden to the public to treat or prevent infectious diseases has been conservatively estimated to exceed $120 billion annually. The problem of emergent infections, combined with the need to provide quality healthcare at a reasonable cost, have led to a reexamination of the approaches used to combat infectious diseases. Immune System The human immune system is a complex system of checks and balances, coupled with an intricate network of cells and effector molecules, which has evolved to stave off the intrusion of foreign elements into the body. To accomplish this the body has developed a means to determine the difference between self and non-self ("foreign"). Foreign substances include elements such as dust particles, pollen grains, infectious agents and antigens (the surface of these other structures generally are covered with antigens, or secrete them). Once the determination has been made that a foreign intruder exists, the body's defenses are triggered, beginning a cascade of events known collectively as the immune response. The end result, in a healthy person, is the successful clearance or elimination of the offending material. The immune response has been divided into two arms based principally on the ultimate effector mechanism which will fight the initial insult; these arms are known as the humoral and cellular immune responses. The humoral immune system employs a family of molecules circulating in the blood stream known as immunoglobulins, or antibodies, which are secreted by immune cells called lymphocytes. In terms of infectious diseases, these antibodies are very effective at combating invasions by bacteria, protozoan parasites, and some viruses, as well as specific proteins produced by these infectious agents. In contrast, a cellular immune response, as the name implies, uses effector cells of the immune system to generally target certain viruses and cancer cells. A different delineation also exists within the immune system in terms of the site of the induction and the response of the immune system. The systemic immune system is generally regarded as that which is internal to the body, including the antibodies in the blood stream and lymphatic system and the cellular immune response in the tissues where foreign agents have encroached. The other active site, and the focus of the Company's vaccine efforts, is the mucosal immune system. This portion of the immune system is spread over the tissues lining the cavities of the body and those involved in the secretions which ultimately find their way to these cavities. Included in this vast network are the linings of the oral and nasopharyngeal cavity, the respiratory tract, the gastrointestinal tract, and the urogenital tract. There are a number of physical barriers present which can prevent the invasion of infectious agents into the mucosal lining. Among these physical factors are: (i) the mucus which covers the lining of mucosal tissues; (ii) the production of protein degrading enzymes which digest proteins either free in the mucosal environment or attached to infectious organisms, thereby decreasing their ability to invade the mucosal tissues; (iii) the peristaltic motion of the walls beneath the mucosa which function in moving digested food and, consequently, infectious agents which are present, through the digestive tract and out of the body; (iv) the motion of the cilia lining the mucosal cavities which carry infectious organisms through the body; and (v) the specialized cells which line the mucosa coupled with the tight junctions between them also provide a strong barrier to the penetration of infectious organisms into the deeper tissues. 30 The specific response which occurs in the mucosal immune system begins with the uptake of the infectious agent or antigen generally by a specialized cell lining the mucosa called an M cell. This cell facilitates the movement of the antigen to cells underlying the epithelial layer which can efficiently prepare the antigen and present it to cells of the immune system. Once stimulated, these cells can migrate to various parts of the mucosal system where they can either produce antibodies or induce effector cells specific for the offending (or, in the case of vaccines, immunizing) agent. Due to this migratory nature of the immune cells of the mucosal immune system, the entire system has been termed the common mucosal immune system. As a result of this trafficking of immune cells, induction of a mucosal immune response at one site results in the expression of that specific response at multiple sites within the mucosal system; i.e. induction of an immune response in the oral cavity would lead to an immune response there, but also in the gut. The weakness of this common mucosal system is that generally the immune response is greater at the site of stimulation than at distant sites within the system, a problem which the Company hopes to circumvent using the site-specific aspects of its commensal vaccine delivery system. The primary effector molecule of the mucosal immune response is an antibody known as secretory immunoglobulin A (sIgA), which is found in saliva, tears, and other secretions of the respiratory, gastrointestinal ("GI"), and urogenital tracts. Given that the mucosal surface covers such a large area, it is not surprising that the sIgA produced there accounts for greater than 75% of all the antibodies produced in the body. sIgA performs a variety of important functions, including: (i) neutralization of viruses, toxins, and enzymes; (ii) inhibition of adherence of microorganisms to mucosal surfaces; (iii) immune exclusion of macromolecules and bacterial toxins; (iv) suppression of antibody-mediated inflammatory responses at mucosal surfaces; (v) synergism with nonspecific antibacterial factors, such as lactoferrin, peroxidase, and lysozyme; (vi) clearance of adsorbed antigen from the circulation; and (vii) interference with other infectious determinants. These factors, coupled with the non-specific barriers described above, form a formidable obstacle to invading infectious organisms. Vaccines Vaccines prevent disease by stimulating the body to produce a protective immune response to particular disease-causing organisms, or pathogens. Conventional vaccines consist of killed microorganisms (e.g. pertussis vaccine), live attenuated microorganisms (e.g. polio or smallpox vaccines) or components of microorganisms, called subunit vaccines (e.g. hepatitis B vaccine). These types of vaccines have been successful in many cases, as evidenced by the global eradication of smallpox through immunization. However, conventional vaccines can have significant limitations. For example, killed vaccines and component vaccines can have variable efficacy and may require boosters to maintain immunity. Attenuated vaccines, while generally more effective, can be associated with certain medical complications, such as neurological damage, allergic reaction, bleeding and infection. There are also a number of diseases for which conventional approaches have not been able to evoke a protective immune response. Aside from the oral polio vaccine, all of these vaccines are administered via the systemic route, i.e. through a needle. The World Health Organization has recently reported that in Eastern Europe 50% of the vaccine centers gave unsafe vaccines or used vaccines of doubtful potency. While clearly there are many factors contributing to this problem, one of the solutions is to alter the manner in which vaccines are delivered. Most infectious agents enter the host's body through and initiate infection at one of the mucosal surfaces--the mouth, the nose, the lungs or the GI or urogenital tracts. For example, the influenza virus usually enters the body through the mouth or nose, salmonella through the GI tract and chlamydia through the urogenital tract. The body's mucosal surfaces present a physical barrier to pathogens and also possess a specific local immune system, which provides a primary line of defense against invading organisms. While conventional vaccines are designed to produce an effective systemic (internal) immune response, they are relatively ineffective at stimulating the mucosal immune system. It is now well recognized in the scientific and medical communities that the mucosal immune system represents an important target for immunization and that vaccines designed to activate the mucosal immune system may prevent a variety of diseases for which conventional vaccines provide only limited protection or do not exist. 31 Anti-infectives and Drug Resistance Since their introduction in the 1940s, antibiotics have been the first line of defense against bacterial infections. Over the past few decades, however, bacterial resistance to existing antibiotics has been increasing, rendering some previously innocuous infections virtually untreatable. All current classes of antibiotics function by interfering with either the structure or the metabolism of a bacterial cell, affecting its ability to survive and to reproduce. For example, penicillin prevents production of new bacterial cell walls, tetracycline inhibits the synthesis of new bacterial proteins, fluoroquinolones inhibit nucleic acid synthesis, and polymyxin B disrupts the integrity of bacterial membranes. Within any given population of infectious organisms, there are generally some cells which are not susceptible to the antibiotic selected for treatment. Because this population is so small, the host can usually remove the remainder of the resistant cells by its normal clearance mechanisms. If, however, a population of pathogens is given the opportunity to increase the percentage of resistant organisms within its number, then eventually the resistant organisms will predominate. There are several reasons for the recent emergence of antibiotic resistance in microorganisms: (i) indiscriminate prescribing of antibiotics by physicians to patients who do not require antibiotic treatment; (ii) non-compliance of dosing regimens by patients leading to incomplete clearance of the infectious agent; (iii) transfer of resistance genes from one organism to another; and (iv) the widespread use of antibiotics in cattle, which ultimately enters the human food chain. Antibiotic resistance has become a problem with many medically important bacteria, but has become particularly dangerous with respect to Mycobacterium tuberculosis (which causes TB), Neisseria gonorrheae (gonorrhea), Pseudomonas aeruginosa (infections in immunocompromised patients), S. aureus (hospital- acquired and other infections), Streptococcus pneumoniae (pneumonia, otitis media, meningitis), and Enterococcus spp. (bacteremia and GI tract infections). While new generations of antibiotics have been developed with broad spectrum activity, only one new class of antibiotics has been developed in the last two decades. The need for new classes of antibiotics and new targets for their action has become crucial to the health of the nation and the world. THE COMPANY'S TECHNOLOGIES Vaccine Technologies: Mucosal Immunity and Vaccine Delivery Using proprietary technology licensed from Rockefeller, the Company is developing certain commensal bacteria ("commensals") as a means to deliver mucosal vaccines. Commensals are harmless bacteria that naturally inhabit the body's surfaces--with different commensals inhabiting different surfaces, particularly the mucosal surfaces. The Company's vaccine candidates utilize genetically engineered commensals to deliver antigens from a variety of pathogens to the mucosal immune system. When administered, the genetically engineered ("recombinant") commensals colonize the mucosal surface and replicate. By activating a local mucosal immune response, the Company's vaccine candidates are designed to prevent infection and disease at the earliest possible stage. By comparison, most conventional vaccines are designed to act after infection has already occurred. The Company's commensal vaccine candidates utilize gram-positive bacteria, one of two major classes of bacteria. Rockefeller scientists have identified a protein region that is used by gram-positive bacteria to anchor proteins to their surfaces. The Company is using the proprietary technology licensed from Rockefeller to fuse antigens from a wide range of infectious organisms, both viral and bacterial, to the surface protein anchor region of a variety of commensal organisms. By combining a specific antigen with a specific commensal, vaccines can be tailored to both the target pathogen and its mucosal point of entry. To target an immune response to a particular mucosal surface, a vaccine would employ a commensal organism that naturally inhabits that surface. For example, vaccines targeting sexually transmitted diseases could employ Lactobacillus acidophilus, a commensal colonizing the female urogenital tract. Vaccines targeting GI diseases could employ Lactobacillus casei, a commensal colonizing the GI tract. The Company has conducted initial experiments using Streptococcus gordonii ("S. gordonii"), a commensal that colonizes the oral cavity and that can potentially be used in vaccines targeting pathogens that enter through the upper respiratory tract, such as the influenza virus. 32 By using an antigen unique to a given pathogen, the technology can potentially be applied to any infectious agent that enters the body through a mucosal surface. The Company's founding 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 cause 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. The Company believes this technology will enable the expression of essentially any antigen regardless of size or shape. In animal studies, the Company has shown that the administration of a recombinant S. gordonii vaccine prototype induces both a local mucosal immune response and a systemic immune response. The Company believes that mucosal vaccines developed using its proprietary commensal delivery technology could provide a number of advantages, including: More complete protection than conventional vaccines: Mucosal vaccines in general may be more effective than conventional parenteral (injectable) vaccines, due to their ability to produce both a systemic and local (mucosal) immune response. By stopping infectious organisms at the earliest stage, the immune response has no need to eliminate pathogens which have already become established in the host. Potential single dose administration: The commensal delivery has the potential to allow for long term colonization of the host, eliminating the need for boosters, while providing an extended exposure to the selected vaccine candidate(s). 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 harmless nature, offer a safer delivery vehicle without fear of genetic reversion to the infectious state inherent in attenuated pathogens. Non-injection administration: Oral, nasal, rectal or vaginal administration of the vaccine eliminates the need for painful injections with their potential adverse reactions. Potential for combined vaccine delivery: The Children's Vaccine Initiative 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. The Company believes its commensal delivery technology can be an effective method of delivery of multi-component vaccines within a single commensal organism that address multiple diseases or diseases caused by multiple strains of an infectious agent. 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. 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. 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 cells 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 produce the molecules (toxins) which result in the outward manifestations of the disease. 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 non-specific mechanisms or its highly specific immune responses to clear or destroy the organisms. 33 Unlike conventional antibiotics, as discussed above, the Company's 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. The Company is pursuing two anti-infective strategies: (i) inhibiting the expression of bacterial surface proteins required for bacterial infectivity and (ii) blocking the tissue binding sites on bacterial surface proteins. The Company believes that these approaches have 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 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 the Company's founding scientists at Rockefeller 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. The Company is using 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 S. aureus, Streptococcus pneumoniae, and the enterococci. 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 this 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, the Company has taken advantage of its 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, the Company has 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. The Company believes 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. THE COMPANY'S PRODUCT CANDIDATES AND RESEARCH AND DISCOVERY PROGRAMS The following table lists the potential indications and current status of the Company's product candidates and research and discovery programs. A more detailed description of these product candidates and research and discovery programs follows this table. The Company's product candidates are subject to the risks of failure inherent in the development of products based on innovative technologies. See "Risk Factors--Early Stage of Development; Absence of Products; No Commercialization of Products Expected in Near Future." 34

- -------- * "Research" activities include initial research and development related to specific vaccine or antibiotic compounds or formulations and their delivery. "Pre-clinical" indicates that the Company is conducting pharmacology testing, toxicity testing, formulation process development and/or development of the manufacturing process prior to possible submission of an IND. Mucosal Vaccines Development of the Company's mucosal vaccine candidates involves: (i) identifying a suitable immunizing antigen from a pathogen; (ii) selecting a commensal that naturally colonizes the mucosal point of entry for that pathogen; and (iii) genetically engineering the commensal to express the antigen on its surface for subsequent delivery to the target population. Strep Throat Vaccine Candidate. Until the age of 15, many children suffer recurrent strep throat infections. Up to five 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 decade, 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 seven to 20 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 the Company for vaccination. Worldwide, it is estimated that one percent of all school age children in the developing world have rheumatic heart disease. 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 large number of cases. No vaccine for strep throat has been developed because of the problems associated with identifying an antigen that is common to the more than 100 different serotypes of group A streptococcus, the bacterium that causes the disease. The Company has 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. Utilizing this antigen, the Company is developing a mucosal vaccine for strep throat. The Company's technology expresses the strep throat antigen on the surface of the commensal, S. gordonii, which lives on the surface of the teeth and gums. The Company believes that a single oral dose of the vaccine may be adequate to provide protection. Indeed, investigators at other institutions have shown that organisms of this type can safely colonize in the human oral cavity for up to two years. The Company is currently completing pre-clinical development of its strep throat vaccine candidate. Pre-clinical research in mice and rabbits has 35 established the ability of this vaccine candidate to colonize and induce both a local and systemic immune response. The Company is collaborating with the National Institutes of Health and the University of Maryland Center for Vaccine Development on the clinical development of this vaccine candidate and expects to file an IND with the FDA in the fall of 1997. STD Vaccine Candidates. One of the great challenges in vaccine research remains the development of effective vaccines to prevent sexually transmitted viral diseases. The three principal viral pathogens which are transmitted via this route are Herpes simplex, type 2 ("HSV-2") which causes recurrent genital ulcers, HIV, the causative agent of AIDS, and human papilloma virus (HPV) which is linked to both genital warts and cervical carcinoma. To date, a great deal of effort has been expended, without appreciable success, to develop effective injectable prophylactic vaccines versus these pathogens. Given that each of these viruses enters the host through the mucosa, the Company believes that induction of a vigorous mucosal response to viral antigens may protect against acquisition of the initial infection. To test this hypothesis, the Company is expressing known immunodominant antigens from each of these viral pathogens in its proprietary mucosal vaccine delivery system. These live recombinant vaccines will be delivered to animals and tested for local and systemic immune response induction, and whether these responses can block subsequent viral infections. The Company is collaborating with Chiron on research toward the development of vaccines against two sexually transmitted diseases. Periodontal Vaccine Candidate. Periodontal disease is characterized by acute soft tissue inflammation and subsequent alveolar bone loss. It is estimated that this condition afflicts up to 50% of the adult population by the time they reach age 65. Current treatments include mechanical debridement, tissue resection and/or antibiotic therapy. It is believed that periodontal disease is the result of an interaction between the immune system or the host and a number of oral bacterial pathogens, principally Porphyromonas gingivalis ("P. gingivalis"). The Company has entered into a research agreement with SUNY Buffalo to develop a mucosal vaccine to prevent periodontal disease. The vaccine, as currently constructed, features a surface antigen, fimbrillin, from P. gingivalis delivered to the oral cavity via the Company's proprietary mucosal vaccine delivery system. In pre-clinical trials, mucosal immunization with, or direct delivery of, fimbrillin-derived peptides to the oral cavity of germ-free rats blocked the ability of P. gingivalis to colonize in the rats upon subsequent challenge and dramatically reduced associated periodontal disease and bone loss. Two vaccine candidates are currently being studied in pre-clinical animal colonization and challenge experiments. Mucosal Vaccine Delivery System The Company's commensal vaccine candidates utilize gram-positive bacteria as vectors for the presentation of antigens. Scientists at Rockefeller have identified a protein region used by gram-positive bacteria to anchor proteins to their surfaces. The Company is using proprietary technology licensed from Rockefeller to fuse antigens from a wide range of infectious organisms, both viral and bacterial, to the surface protein anchor region of a variety of commensal organisms. By combining a specific antigen with a specific commensal, the Company believes that vaccines can be tailored to both the target pathogen and its mucosal point of entry. The Company has developed several genetic methods for recombining foreign sequences into the genome of gram-positive bacteria at a number of non- essential sites. Various parameters have been tested and optimized to improve the level of foreign protein expression and its immunogenicity. In pre- clinical studies, recombinant commensals have been implanted into the oral cavities of several animal species with no deleterious effects. The introduced vaccine strains have taken up residence for prolonged periods of time and induce both a local mucosal (IgA) as well as a systemic immune response (IgG and T-cell). Anti-Infectives More than two million nosocomial infections occur each year. Of these, a large number are due to the pathogenic gram-positive bacteria. Many of these bacteria have acquired antibiotic resistance and have become an increasing problem. The gram-positive bacteria principally involved in these nosocomial infections include: S. aureus, coagulase-negative staphylococci and enterococci. S. aureus has been described above. The coagulase- 36 negative staphylococci have become the leading cause of nosocomial bacteremia and, alarmingly, have shown a higher percentage of methicillin resistant strains (up to 78%) than S. aureus (up to 22%). The enterococci have shown a disturbing propensity toward resistance to the antibiotic of last resort, vancomycin. Even more alarming is the fact that in certain cases where the last antibiotic of choice to treat a S. aureus or coagulase-negative infection is vancomycin, some strains of enterococci have evolved that may actually thrive on vancomycin, rendering the treatment potentially life threatening. Another important gram-positive organism with an increasing presence of antibiotic resistance is Streptococcus pneumoniae, an organism responsible for pneumonia and meningitis, and which is the leading cause of middle ear infections in children. Scientists at Rockefeller have determined that many different surface proteins from a variety of gram-positive bacteria are attached to the bacterial surface via a common anchoring mechanism. These surface proteins are responsible for a wide variety of functions essential to the successful establishment of infection by the organism, including adherence, binding to serum proteins, resistance to phagocytosis (ingestion and destruction by the host's cells), cross-signaling between the bacterium and the host's cells, and various enzymatic processes. The Company has identified an enzyme, a selective protease, utilized by most gram-positive bacteria to anchor certain proteins to the bacterial cell wall. The Company will attempt to identify compounds that will inhibit this protease, thereby blocking the anchoring process and the ability of the bacteria to initiate or prolong infection. In this process, the Company is using molecular modeling to identify possible structures of the anchor region. Once these structures are identified, natural and synthetic molecules that may inhibit the anchoring process will be screened using an existing high throughput assay developed by Rockefeller and licensed to the Company. The Company believes that this approach represents a departure from conventional antibiotics and therefore may afford a method to circumvent the resistance mechanisms already established in many gram-positive organisms. The Company has entered into an agreement with Wyeth-Ayerst to identify and develop protease inhibitors as novel antibiotics. SPEX The Company's proprietary SPEX protein expression uses the protein export and anchoring pathway of gram-positive bacteria as a means to facilitate the production and purification of biopharmaceutical proteins. The Company has developed vectors which allow foreign genes to be inserted into the chromosome of gram-positive bacteria in a manner such that the encoded protein is synthesized, transported to the cell surface and secreted into the medium. This system has been used to produce milligram quantities of soluble antigenically-authentic protein that can be easily purified from the culture medium by affinity chromatography. The Company believes this technology can be extended to a variety of different antigens and enzymes. MedImmune Technology The Company has entered into a letter of intent with MedImmune regarding a technology transfer agreement pursuant to which the Company will acquire all of MedImmune's rights in gram-negative antibiotic targets, products, screens and services. Such rights include MedImmune's rights to technology developed by scientists at Washington University. Research carried out by these scientists has demonstrated that assembly of type P pili on gram-negative bacteria requires the participation of both a periplasmic molecular chaperone and an outer membrane usher. Since the gram-negative pili are the primary mechanism by which these organisms adhere to and colonize host tissue, inhibition of their assembly should effectively inhibit disease caused by this class of organisms. Detailed structural data is available on the molecular chaperone and scientists at Washington University are developing the same for the usher protein. This information will be used in concert with molecular modeling techniques to identify potential structures that will bind to the conserved residues of the chaperone and usher proteins. Once these structures are identified, natural and synthetic molecules that inhibit chaperone/usher function will be screened using high throughput assays developed by scientists at Washington University. The Company believes that this approach is a departure from conventional antibiotics and therefore may afford a method to circumvent the resistance mechanisms already established in many gram-negative bacteria. There can be no assurance that the Company will enter into a final agreement with MedImmune, and, therefore, there can be no assurance that the Company will acquire the rights to the technology described above. See "Risk Factors--Dependence on Others; Collaborations." 37 COLLABORATIVE RESEARCH AND LICENSES The Company sponsors research and development activities in laboratories at Rockefeller, Emory, Oregon State, and SUNY Buffalo and does not maintain its own research and development facilities. The Company's research is conducted by its employees and employees of the aforementioned universities. The Company's two principal research scientists, Dr. Vincent Fischetti, whose laboratory is at Rockefeller, and Dr. Dennis Hruby, whose laboratory is at Oregon State, work together to coordinate the Company's research projects. The majority of the Company's molecular biology and genetic research is conducted at Oregon State and the bulk of its bacteriology and immunology research is conducted at Rockefeller. The Company has entered into the following license agreements and collaborative research arrangements: Rockefeller University.

Pursuant to the agreement, each company retains sole rights to any technology invented solely by such company and the companies will jointly own any technology jointly developed by the companies. In addition, the Company has entered into a letter of intent with MedImmune regarding a technology transfer agreement pursuant to which the Company will acquire all of MedImmune's rights in gram-negative antibiotic targets, products, screens and services. The Company and MedImmune plan to collaborate in the development of antibiotics against gram-negative pathogens. The Company and MedImmune contemplate that upon the execution of the technology transfer agreement, MedImmune will receive 335,530 shares of Common Stock. There can be no assurance that the Company will enter into a final agreement with MedImmune on the terms described above or at all. See "Risk Factors--Dependence on Others; Collaborations." MANUFACTURING The Company does not intend to invest in large scale manufacturing facilities unless and until its product candidates pass significant developmental hurdles. The Company believes that all of its existing products under development can be made using well understood manufacturing methods. Nevertheless, the Company has no manufacturing experience and it may not be able to develop reproducible and effective manufacturing processes at a reasonable cost. In such event, the Company will have to rely on third party manufacturers whose availability and cost are presently unknown. The Company plans to contract with third party manufacturers to produce pre-clinical and clinical lots of its biological products. No assurances can be given that the Company will establish such relationships or manufacture its product candidates successfully. See "Risk Factors--Lack of Manufacturing, Marketing or Sales Capabilities." MARKETING The Company currently has no internal marketing and sales resources and personnel. The Company recognizes the challenges associated with marketing and sales in the pharmaceutical industry and anticipates undertaking these activities only for products that address large but focused therapeutic markets in which a small marketing organization can compete effectively. It is, however, the Company's present intention to seek marketing partners to assist it in later stages of regulatory and clinical development, process scale up, production and marketing. No assurances can be given that the Company will establish such relationships or market its product candidates successfully. See "Risk Factors--Lack of Manufacturing, Marketing or Sales Capabilities." PATENTS AND PROPRIETARY RIGHTS Protection of the Company's proprietary compounds and technology is essential to the Company's business. The Company's policy is to seek, when appropriate, protection for its lead compounds and certain other proprietary technology by filing patent applications in the United States and other countries. The Company has licensed the rights to two issued United States patents and one issued European patent. The Company has also licensed the rights to 11 pending United States patent applications as well as corresponding foreign patent applications. The two issued United States patents expire in 2005 and 2014, respectively. The patents and patent applications licensed by the Company relate to all of the core technology used in the development of the Company's leading product candidates, including the mucosal vaccine delivery system, the SPEX protein expression system for producing biopharmaceutical products, the protective streptococcal antigens and the antibiotic development target, as well as a variety of early stage research projects. Each of the Company's products represented by each of the patents is in a very early stage in its development process. 39 The Company also relies upon trade secret protection for its confidential and proprietary information. No assurance can be given that other companies will not independently develop substantially equivalent proprietary information and techniques or otherwise gain access to the Company's trade secrets or that the Company can meaningfully protect its trade secrets. The Company requires its employees, consultants, outside scientific collaborators and sponsored researchers and certain other advisors to enter into confidentiality agreements with the Company. These agreements will provide that all confidential information developed or made known to the individual during the course of the individual's relationship with the Company will be kept confidential and will not be disclosed to third parties except in specific circumstances. In the case of employees, such agreements will provide that all inventions conceived by the employee are the exclusive property of the Company. There can be no assurance, however, that these agreements will provide meaningful protection or adequate remedies for the Company's trade secrets in the event of unauthorized use or disclosure of such information. 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 products that may be developed by the Company. The nature and the extent to which such regulation may apply to the Company will vary depending on the nature of any such products. Virtually all of the Company's potential 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. In order to test clinically, produce and market products for diagnostic or therapeutic use, a company must comply with mandatory procedures and safety standards established by the FDA and comparable agencies in foreign countries. 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 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 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 or not 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, and there can be no assurance that any approvals will be granted on a timely basis, if at all. 40 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 the Company may be marketed impose a similar regulatory process. COMPETITION The biotechnology and pharmaceutical industries are characterized by rapidly evolving technology and intense competition. The Company's competitors include most of the major pharmaceutical companies, which have financial, technical and marketing resources significantly greater than those of the Company. Biotechnology and other pharmaceutical competitors include Cubist Pharmaceuticals, Inc., Microcide Pharmaceuticals, Inc., Oravax, Inc., Maxim Pharmaceuticals, Inc., and Vaxcel, 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 the Company's competitors will not succeed in developing products that are more effective or less costly than any which are being developed by the Company or which would render the Company's technology and future products obsolete and noncompetitive.

The Company leases office space at 666 Third Avenue, New York, New York, 10017. See "Risk Factors--Lack of Research and Development Facilities." PRODUCT LIABILITY INSURANCE The Company's business exposes it to potential liability risks that are inherent in the testing, manufacturing and marketing of pharmaceutical products. The Company does not have product liability insurance but intends to obtain such coverage if and when its product candidates are tested in clinical trials. There can be no assurance, however, that the Company will be able to obtain insurance coverage at acceptable costs or in a sufficient amount, if at all, or that a product liability claim would not adversely affect the Company's business, operating results or financial condition. See "Risk Factors--Potential Product Liability and Availability of Insurance."

An Incentive Option is intended to qualify as an incentive stock option within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the "Code"). Any Incentive Option granted under the Plan will have an exercise price of not less than 100% of the fair market value of the shares on the date on which such option is granted.

Pursuant to the terms of the agreement, CSO receives an annual fee of $120,000 and will be reimbursed for certain expenses. The agreement expires on January 15, 1998 and is cancelable by the Company only for cause as defined in the agreement. Mr. Cooper, Dr. Schein and Steven Oliveira are the members of CSO. In March 1996, Dr. Fischetti and the Company entered into an agreement pursuant to which Dr. Fischetti was to receive options to purchase up to 150,000 shares of Common Stock upon the completion of collaborative agreements with certain pharmaceutical companies. On September 15, 1996, such agreement was cancelled and Dr. Fischetti received warrants to purchase 150,000 shares of Common Stock at $1.50 per share as compensation for introducing the Company to certain potential collaborative pharmaceutical companies. The Company believes that the terms of the transactions described above were no less favorable than the Company could have obtained from unaffiliated third parties. The Company has adopted a policy, effective following the consummation of this Offering, that all future transactions between the Company and its officers, directors and affiliates must (i) be approved by a majority of those members of the Company's Board of Directors that are not parties, directly or indirectly through affiliates, to such transactions and (ii) be on terms no less favorable to the Company than could be obtained from unrelated third parties. DESCRIPTION OF SECURITIES The Company is authorized to issue 25,000,000 shares of Common Stock, par value $.0001 per share, and 10,000,000 shares of Preferred Stock, par value $.0001 per share. As of the date of this Prospectus, there are 3,367,182 shares of Common Stock outstanding and no shares of Preferred Stock outstanding. The following summary description of the Company's Common Stock and Preferred Stock is qualified in its entirety by reference to the Articles and Bylaws, copies of which are included as exhibits to the Registration Statement of which this Prospectus is a part. COMMON STOCK Holders of Common Stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders and do not have cumulative voting rights. Accordingly, holders of a majority of the shares of Common Stock entitled to vote in any election of directors may elect all of the directors standing for election. Holders of Common Stock are entitled to receive ratably such dividends, if any, as may be declared by the Board of Directors out of funds legally available therefor, subject to any preferential dividend rights of any outstanding Preferred Stock. Upon the liquidation, dissolution or winding up of the Company, the holders of Common Stock are entitled to receive ratably the net assets of the Company available after the payment of all debts and other liabilities and subject to the prior rights of any outstanding Preferred Stock. Holders of Common Stock have no preemptive, subscription, redemption or conversion rights. The outstanding shares of Common Stock are, and the shares offered by the Company in this Offering will be, when issued and paid for, fully paid and nonassessable. The rights, preferences and privileges of holders of Common Stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of Preferred Stock which the Company may designate and issue in the future. PREFERRED STOCK The Board of Directors has the authority, without further action of the stockholders of the Company, to issue up to an aggregate of 10,000,000 shares of Preferred Stock in one or more series and to fix or alter the 50 designations, preferences, rights and any qualifications, limitations or restrictions of the shares of each such series thereof, including the dividend rights, dividend rates, conversion rights, voting rights, terms of redemption (including sinking fund provisions), redemption price or prices, liquidation preferences and the number of shares constituting any series or the designation of such series. The Board of Directors, without stockholder approval, can issue Preferred Stock with voting and conversion rights that could adversely affect the voting power of holders of Common Stock. The issuance of Preferred Stock may have the effect of delaying, deferring or preventing a change in control of the Company. The Company has no present plans to issue any shares of Preferred Stock. TRANSFER AGENT The Company's transfer agent and registrar for the Common Stock is American Stock Transfer & Trust Company. INDEMNIFICATION The Certificate of Incorporation (the "Certificate") of the Company provides that, to the fullest extent permitted by applicable law, as amended from time to time, the Company will indemnify any person who was or is a party or is threatened to be made a party to an action, suit or proceeding (whether civil, criminal, administrative or investigative) by reason of the fact that such person is or was director, officer, employee or agent of the Company or serves or served any other enterprise at the request of the Company. In addition, the Certificate provides that a director of the Company shall not be personally liable to the Company or its stockholders for monetary damages for breach of the director's fiduciary duty. However, the Certificate does not eliminate or limit the liability of a director for any of the following reasons: (i) a breach of the director's duty of loyalty to the Company or its stockholders; (ii) acts or omissions not in good faith or that involve intentional misconduct or knowing violation of law; or (iii) a transaction from which the director derived an improper personal benefit. The Company will purchase and maintain Directors' and Officers' Insurance as soon as the Board of Directors determines practicable, in amounts which they consider appropriate, insuring the directors against any liability arising out of the director's status as a director of the Company regardless of whether the Company has the power to indemnify the director against such liability under applicable law. The Company has been advised that it is the position of the Commission that insofar as the foregoing provisions may be invoked to disclaim liability for damages arising under the Securities Act, such provisions are against public policy as expressed in the Securities Act and are, therefore, unenforceable. CERTAIN CERTIFICATE OF INCORPORATION AND BYLAW PROVISIONS In addition, certain provisions of the Company's Certificate and Bylaws summarized in the following paragraphs may be deemed to have an anti-takeover effect and may delay, defer or prevent a tender offer or takeover attempt that a stockholder might consider in its best interest, including those attempts that might result in a premium over the market price for the shares held by stockholders. Special Meeting of Stockholders The Company's Bylaws provide that special meetings of stockholders of the Company may be called only by the President of the Company, the Board of Directors or holders of not less than 10% of the votes entitled to be cast at the special meeting. 51 Authorized But Unissued Shares The authorized but unissued shares of Common Stock and Preferred Stock are available for future issuance without stockholder approval. These additional shares may be utilized for a variety of corporate purposes, including future public offerings to raise additional capital, corporate acquisitions, poison pills and employee benefit plans. The existence of authorized but unissued and unreserved Common Stock and Preferred Stock may enable the Board of Directors to issue shares to persons friendly to current management which could render more difficult or discourage an attempt to obtain control of the Company by means of a proxy contest, tender, offer, merger or otherwise, and thereby protect the continuity of the Company's management. SHARES ELIGIBLE FOR FUTURE SALE Upon completion of this Offering, the Company will have outstanding 5,867,182 shares of Common Stock, without giving effect to (a) shares of Common Stock issuable upon exercise of (i) the Underwriters' Over-allotment Option, (ii) the Representatives' Warrants, (iii) options granted under the Plan, (iv) the de Weese Warrants, (v) the Fischetti Warrants, (vi) the Directors/Advisors Warrants or (vii) the Bridge Warrants or (b) the MedImmune Shares. There can be no assurance that the Company will enter into a final agreement with MedImmune on the terms described herein or at all. See "Risk Factors--Dependence on Others; Collaborations." Of such outstanding shares of Common Stock, all the shares to be sold by the Company in this Offering will be freely tradeable without restriction or further registration under the Securities Act, except for any shares held by "affiliates" of the Company within the meaning of the Securities Act which shares will be subject to the resale limitations of Rule 144 promulgated under the Securities Act. In addition, the estimated 100,000 shares of Common Stock issuable upon the exercise of the Bridge Warrants, all of which also are being registered under the Securities Act pursuant to the registration statement of which this Prospectus constitutes a part, will be freely transferable under the Securities Act, other than those shares held by affiliates of the Company. See "Plan of Operation--Bridge Financing." The remaining 3,367,182 Restricted Shares were issued by the Company in private transactions in reliance upon one or more exemptions contained in the Securities Act. The 1,288,012 Private Shares were issued in connection with two private placement transactions completed in March and September 1996 and the 2,079,170 Founders' Shares were issued to the founders of the Company in December 1995. The Restricted Shares are deemed to be "restricted securities" within the meaning of Rule 144 promulgated pursuant to the Securities Act and may be publicly sold only if registered under the Securities Act or sold pursuant to exemptions therefrom. Because the Founders' Shares and 1,038,008 of the Private Shares acquired in the March 1996 private placement will have been held for more than one year as of the date of this Prospectus, such shares will be eligible for public sale in accordance with the requirements of Rule 144, as described below. In addition, the remaining 250,004 of the Private Shares will be eligible for public sale in September 1997. However, certain holders of the Private Shares and the holders of the Founders' Shares have agreed with Sunrise not to sell or otherwise dispose of such shares for a period of six months and 24 months, respectively, after the date of the consummation of the Offering. In general, under Rule 144, as amended, subject to the satisfaction of certain other conditions, a person, including an affiliate of the Company (or persons whose shares are aggregated with an affiliate), who has owned restricted shares of Common Stock beneficially for at least one year is entitled to sell, within any three-month period, a number of shares that does not exceed the greater of one per cent of the total number of outstanding shares of the same class or, if the common stock is quoted on Nasdaq, the average weekly trading volume during the four calendar weeks preceding the sale. A person who has not been an affiliate of the Company for at least three months immediately preceding the sale and who has beneficially owned shares of the Company for at least two years is entitled to sell such shares under Rule 144 without regard to any of the limitations described above. The Company intends to file a registration statement under the Securities Act to register shares of Common Stock reserved for issuance under the Plan, thereby permitting the resale of such shares by non-affiliates in the public market without restriction under the Securities Act. The Company has reserved up to 333,333 shares of 52 Common Stock for issuance under the Plan. As of the date of this Prospectus, options to purchase 60,001 of such reserved shares of Common Stock were outstanding under the Plan. See "Management--1996 Incentive and Non-Qualified Stock Option Plan." Prior to this Offering, there has been no public market for the Common Stock, and no predictions can be made as to the effect, if any, that sales of the Common Stock will have on the market price of such securities from time to time. Sales of substantial amounts of the Company's securities in the public market could have a significant adverse effect on prevailing market prices and could impair the Company's future ability to raise capital through the sale of its equity securities. See "Risk Factors--Shares Eligible for Future Sale." UNDERWRITING The Underwriters below have severally agreed, subject to the terms and conditions contained in the Underwriting Agreement, to purchase from the Company the number of shares of Common Stock set forth below opposite their respective names:
NUMBER OF UNDERWRITER SHARES ----------- --------- Sunrise Securities Corp.......................................... 1,900,000 M.H. Meyerson & Co., Inc. ....................................... 600,000 --------- Total.......................................................... 2,500,000 =========
The Underwriting Agreement provides that the obligations of the several Underwriters thereunder are subject to approval of certain legal matters by counsel and to various other conditions. The nature of the Underwriters' obligations is such that they are committed to purchase and pay for all of the above shares of Common Stock offered hereby if any are purchased. The Underwriters have advised the Company that they propose to offer the shares of Common Stock initially at the public offering price set forth on the cover page of the Prospectus and that the Underwriters may allow to selected dealers a concession of $0.25 per share. After the public offering, the offering price and other selling terms may be changed by the Underwriters. The Common Stock has been approved for quotation on Nasdaq. The Company has granted to the Underwriters a 30-day Underwriters' Over- allotment Option to purchase from the Company up to an aggregate of 375,000 additional shares of Common Stock exercisable at the initial public offering price less the underwriting discount. If the Underwriters exercise such Over- allotment Option, then each of the Underwriters will have a firm commitment, subject to certain conditions, to purchase approximately the same percentage thereof as the number of shares of Common Stock to be purchased by it as shown in the above table bears to the 2,500,000 shares of Common Stock offered hereby. The Underwriters may exercise such Over-allotment Option only to cover over-allotments made in connection with the sale of the shares of Common Stock offered hereby. The Underwriting Agreement provides further that Sunrise will receive from the Company a non-accountable expense allowance of three per cent of the gross proceeds of the Offering, of which $45,000 has been paid by the Company to date. The Company has also agreed to pay all expenses in connection with qualifying the shares of Common Stock offered hereby for sale under the laws of such states as Sunrise may designate, including expenses of counsel retained for such purpose by Sunrise. The Company has agreed to sell to the Representatives, for nominal consideration, the Representatives' Warrants to purchase up to 250,000 shares of Common Stock. The Representatives' Warrants will be nonexercisable for one year after the date of this Prospectus. Thereafter, for a period of four years, the Representatives' Warrants will be exercisable at an amount equal to 165% of the offering price of the Common Stock sold in this Offering. The Representatives' Warrants are not transferable for a period of one year after the date of this Prospectus, except to officers and partners of the Representatives, members of the selling group and their officers and partners. The Company has also granted certain demand and "piggyback" registration rights to the holders of the Representatives' Warrants. 53 For the life of the Representatives' Warrants, the holders thereof are given, at a nominal cost, the opportunity to profit from a rise in the market price of the Common Stock with a resulting dilution in the interest of other stockholders. Further, such holders may be expected to exercise the Representatives' Warrants at a time the Company would in all likelihood be able to obtain equity capital on terms more favorable than those provided in the Representatives' Warrants. Nathan Low, President of Sunrise, beneficially owns an aggregate of 179,436 shares of Common Stock (representing 5.3% of the outstanding Common Stock) of the Company. Richard Stone, a managing director of Sunrise, beneficially owns an aggregate of 414,915 shares of Common Stock (representing 12.3% of the outstanding Common Stock) of the Company. In addition, Steven Oliveira, a registered representative of Hampshire Securities Corporation, which is anticipated to participate in the distribution of the Securities in this Offering, beneficially owns an aggregate of 461,016 shares of Common Stock (representing 13.7% of the outstanding Common Stock). As a result, this Offering is being conducted in accordance with the applicable provisions of Rule 2720 of the NASD Rules of Conduct. Accordingly, the initial public offering price can be no higher than that recommended by a "qualified independent underwriter" meeting certain standards. Loeb Partners Corporation served as qualified independent underwriter in connection with this Offering. Loeb Partners Corporation has assumed the responsibilities of acting as qualified independent underwriter in pricing the Offering, has performed due diligence with respect to the information contained herein and has participated in preparing the Registration Statement. In its role as qualified independent underwriter, Loeb Partners Corporation will receive an aggregate fee from the Underwriters of $25,000, $12,500 of which has been paid and $12,500 of which is to be paid upon consummation of the Offering. In addition, Loeb Partners Corporation will be reimbursed by the Underwriters for up to $5,000 for certain expenses incurred in connection with its services, including its independent counsel. The Underwriting Agreement provides for reciprocal indemnification between the Company and the Underwriters against liabilities in connection with the Offering, including liabilities under the Securities Act. The initial public offering price of the shares of Common Stock offered hereby has been determined by negotiation between the Company and the Underwriters, and within the parameters set forth above, and does not necessarily bear any direct relationship to the Company's assets, earnings, book value per share or other generally accepted criteria of value. Factors considered in determining the offering price of the shares of Common Stock included the business in which the Company is engaged, the Company's financial condition, an assessment of the Company's management, the general condition of the securities markets and the demand for similar securities of comparable companies. During and after the Offering, the Underwriters may purchase and sell Common Stock in the open market. These transactions may include stabilizing transactions and purchases to cover short positions created in connection with the Offering. The Underwriters also may impose a penalty bid, whereby selling concessions allowed to broker-dealers in respect of the Common Stock sold in the Offering for their account may be reclaimed if such shares are repurchased by the Underwriters in stabilizing or covering transactions. These activities may stabilize, maintain or otherwise affect the market price of the Common Stock which may be higher than the price that might otherwise prevail in the open market. The Company and the Underwriters make no representation or prediction as to the discretion or magnitude of any effect that the transactions described above may have on the price of the Common Stock. The foregoing includes a summary of the principal terms of the Underwriting Agreement and does not purport to be complete. Reference is made to the copy of the Underwriting Agreement filed as an exhibit to the Registration Statement of which this Prospectus is a part.

F-1 REPORT OF INDEPENDENT ACCOUNTANTS To the Board of Directors and Stockholders of SIGA Pharmaceuticals, Inc. In our opinion, the accompanying balance sheet and related statements of operations, of cash flows and of changes in stockholders' equity present fairly, in all material respects, the financial position of SIGA Pharmaceuticals, Inc. (a development stage company) at December 31, 1995 and 1996, and the results of its operations for the period from inception (December 28, 1995) through December 31, 1995, for the year ended December 31, 1996 and for the period from inception through December 31, 1996, in conformity with generally accepted accounting principles. These financial statements are the responsibility of the Company's management; our responsibility is to express an opinion on these financial statements based on our audit. We conducted our audit of these statements in accordance with generally accepted auditing standards which require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for the opinion expressed above. The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the financial statements, the Company is a development stage company and has suffered operating losses since inception. These and other factors, as discussed in Note 1, raise substantial doubt about its ability to continue as a going concern. Management's plans in regard to these matters are also described in Note 1. The financial statements do not include any adjustments that might result from the outcome of this uncertainty. Price Waterhouse LLP New York, New York March 3, 1997 F-2 SIGA PHARMACEUTICALS, INC.

There were no cash payments for interest or income taxes for the periods ended December 31, 1995 and 1996 and the period ended June 30, 1997. The accompanying notes are an integral part of these financial statements. F-6 SIGA PHARMACEUTICALS, INC. (A DEVELOPMENT STAGE COMPANY) NOTES TO FINANCIAL STATEMENTS (Unaudited with respect to June 30, 1996 and 1997 and for each six month period then ended) 1. ORGANIZATION AND BASIS OF PRESENTATION Organization SIGA Pharmaceuticals, Inc. (the "Company") was incorporated in the State of Delaware on December 28, 1995. 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. The Company's technologies are licensed from third parties and the Company depends on third parties to conduct research on its behalf pursuant to research and consulting agreements. Basis of presentation The Company's activities since inception have consisted primarily of sponsoring research and development, performing business and financial planning, preparing and filing patent applications, and raising capital. Accordingly, the Company is considered to be a development stage company and will require additional financing to achieve commercialization of its technologies. The accompanying financial statements have been prepared assuming the Company will continue as a going concern. Since inception, the Company has incurred cumulative net operating losses and expects to incur substantial additional losses to complete the commercialization of its technologies. These conditions raise substantial doubt about the Company's ability to continue as a going concern. The Company's ability to continue as a going concern is dependent upon its ability to generate sufficient cash flow to meet its obligations as they come due. Management is actively pursuing various options which include securing additional equity financing through an initial public offering and believes that sufficient funding will be available to meet its planned business objectives. The Company has entered into a non-binding letter of intent with an underwriter to sell shares of the Company's common stock in an initial public offering (the "IPO") pursuant to the Securities Act of 1933. The financial statements do not include any adjustments relating to the recoverability of the carrying amount of recorded assets or the amount of liabilities that might result from the outcome of these uncertainties. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Cash equivalents 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. Equipment Equipment is stated at cost. Depreciation is provided on the straight-line method over the estimated useful lives of the respective assets, none of which exceeds three years. Deferred offering costs In connection with the Company's proposed IPO, the Company has incurred certain costs which have been deferred. In the event the proposed IPO is not consummated the deferred offering costs will be expensed. Research and development Research and development costs are expensed as incurred and include costs of third parties who conduct research and development, pursuant to development and consulting agreements, on behalf of the Company. 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 and considered a component of research and development costs. F-7 SIGA PHARMACEUTICALS, INC. (A DEVELOPMENT STAGE COMPANY) NOTES TO FINANCIAL STATEMENTS--(CONTINUED) (Unaudited with respect to June 30, 1996 and 1997 and for each six month period then ended) 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 Net loss per common share is computed using the weighted average number of common shares and common share equivalents assumed to be outstanding during the period. Common share equivalents consist of the Company's common shares issuable upon exercise of stock options and outstanding warrants. Pursuant to the requirements of the Securities and Exchange Commission, stock options, warrants and shares issued by the Company within one year of the date of the initial public offering at prices below the proposed offering price have been included in the calculation of weighted average shares outstanding as if they were outstanding for all periods presented using the treasury stock method. Accounting estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates. Fair value of financial instruments The carrying value of cash and cash equivalents, and accounts payable and accrued expenses approximates fair value due to the relatively short maturity of these instruments. New accounting pronouncements In February 1997, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 128, "Earnings per Share" ("FAS 128") which requires presentation of basic earnings per share ("Basic EPS") and diluted earnings per share ("Diluted EPS") by all entities that have publicly traded common stock or potential common stock (options, warrants, convertible securities or contingent stock arrangements). FAS 128 also requires presentation of earnings per share by an entity that has made a filing or is in the process of filing with a regulatory agency in preparation for the sale of those securities in a public market. Basic EPS is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted EPS gives effect to all dilutive potential common shares outstanding during the period. The computation of Diluted EPS does not assume conversion, exercise or contingent exercise of securities that would have an antidilutive effect on earnings. The statement is effective for both interim and annual periods ending after December 15, 1997. The effect on the Company's earnings per share resulting from the adoption of FAS 128 is not expected to be significant. In June 1997, the Financial Accounting Standards Board issued Statement of Accounting Standards No. 130, "Reporting Comprehensive Income" ("FAS 130"), which requires the presentation of the components of comprehensive income in a company's financial statements for reporting periods beginning subsequent to F-8 SIGA PHARMACEUTICALS, INC. (A DEVELOPMENT STAGE COMPANY) NOTES TO FINANCIAL STATEMENTS--(CONTINUED) (Unaudited with respect to June 30, 1996 and 1997 and for each six month period then ended) December 15, 1997. Comprehensive income is defined as the change in a company's equity during a financial reporting period from transactions and other circumstances from nonowner sources (including cumulative translation adjustments, minimum pension liabilities and unrealized gains/losses on available for sale securities). The adoption of FAS 130 is not expected to have a material impact on the Company's financial statements. 3. EQUIPMENT Equipment consisted of the following at December 31, 1996 and June 30, 1997:

4. STOCKHOLDERS' EQUITY In March 1996, the Company completed a private offering of 1,038,008 shares of its common stock at the price of $1.50 per share, providing gross proceeds of $1,557,000, and net proceeds, after deducting expenses, of $1,551,437. In September 1996, the Company completed a second private offering of 250,004 shares of common stock at a price of $3.00 per share providing gross proceeds of $750,000 and net proceeds, after deducting expenses, of $749,010. Reverse stock split Effective December 1996, the Company implemented a one for six reverse stock split (without changing the par value thereof) applicable to all issued and outstanding shares of the Company's common stock. All fractional shares resulting from such stock split were rounded up to the next whole share. All common shares, stock options, warrants and related per share data, reflected in the accompanying financial statements and notes thereto, have been presented as if such change had occurred at December 28, 1995. Stock option plan and warrants In January 1996, the Company implemented its 1996 Incentive and Non- Qualified Stock Option Plan (the "Plan") whereby options to purchase up to 333,333 shares of the Company's common stock may be granted 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 and become exercisable over a period of three years with a third of the grant being exercisable at the completion of each year of service subsequent to the grant. The fair market value of the Company's common stock is determined by a committee of the Board of Directors. The committee is comprised entirely of employees who receive stock options under the Plan. During the year ended December 31, 1996, the Company granted options under the Plan to employees to purchase 33,334 shares of its common stock at an exercise price of $1.50 per share and options to purchase 16,667 shares at an exercise price of $3.00 per share. These options expire on January 1, 2001 and November 18, 2006, respectively. All such grants were outstanding at December 31, 1996 and were eligible for exercise. There were no grants to outside directors during the year ended December 31, 1996. The weighted-average grant-date fair value of options granted during the year ended December 31, 1996 whose exercise price equaled the fair market F-9 SIGA PHARMACEUTICALS, INC. (A DEVELOPMENT STAGE COMPANY) NOTES TO FINANCIAL STATEMENTS--(CONTINUED) (Unaudited with respect to June 30, 1996 and 1997 and for each six month period then ended) value on the date of grant was $.22. The weighted-average grant-date fair value of options granted during the year ended December 31, 1996 whose exercise price was less than the fair market value on the date of grant was $.99. The weighted-average remaining contractual life of options outstanding at December 31, 1996 was 6.5 years. In November 1996, the Company entered into an employment agreement with its President and Chief Executive Officer. Under the terms of the agreement, the employee received warrants to purchase 461,016 shares of common stock at $3.00 per share. Warrants to purchase 25% of such shares were exercisable upon issuance and the remaining warrants are exercisable on a pro rata basis on the first, second and third anniversaries of the agreement (see Note 8). These warrants expire on November 18, 2006. The grant date fair value of such warrants was $.99. At December 31, 1996, the remaining contractual life of such warrants was approximately 9.9 years. The Company applies Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees," and related interpretations in accounting for warrants issued to employees and stock options granted under the Plan. During the year ended December 31, 1996, compensation expense of $57,627 has been recognized for warrants issued to employees and $8,334 for options issued pursuant to its stock-based compensation plan calculated based upon the difference between the exercise price of the warrant or option and the fair market value of the Company's common stock on the date of grant. Had compensation cost for warrants issued and stock options granted been determined based upon the fair value at the grant date for awards consistent with the methodology prescribed under Statement of Financial Accounting Standards No. 123 ("FAS 123"), "Accounting for Stock-Based Compensation," the Company's net loss and loss per share would have been increased by approximately $72,000, or approximately $.02 per share. In March 1996, the Company entered into an agreement with a consultant, who is a stockholder, whereby the consultant would be granted options to purchase 150,000 shares of the Company's common stock, at an exercise price of $1.50 per share, contingent upon completion of collaborative agreements with specified pharmaceutical companies. In September 1996, such agreement was terminated and the consultant was issued warrants to purchase 150,000 shares of its common stock, at an exercise price of $1.50 per share. The warrants were exercisable upon issuance and expire on the twentieth anniversary of the date of issuance. The Company has recognized non-cash compensation expense of $301,500 for the year ended December 31, 1996, based upon the fair value of such warrants on the date of grant (see Note 6). At December 31, 1996, the remaining contractual life of such warrants was approximately 19.7 years. The fair value of the options and warrants granted to employees and the warrants issued to the consultant during 1996 ranged from $.22 to $2.01 on the date of the respective grant using the Black-Scholes option-pricing model assuming (a) no dividend yield, (b) a risk-free interest rate ranging from 5.26% to 6.26% based on the date of the respective grant, (c) no forfeitures, and (d) an expected life of three years. As permitted under the provisions of FAS 123, and based on the historical lack of a public market for the Company's common stock, no factor for volatility has been reflected in the option and warrant pricing calculation. 5. INCOME TAXES The Company has incurred losses since inception which have generated net operating loss carryforwards of approximately $1,901,000 and $3,185,000, respectively, at December 31, 1996 and June 30, 1997 for federal and state income tax purposes. These carryforwards are available to offset future taxable income and expire in 2011 and 2012 for federal income tax purposes. These losses are subject to limitation on future years' utilization should certain ownership changes occur. F-10 SIGA PHARMACEUTICALS, INC. (A DEVELOPMENT STAGE COMPANY) NOTES TO FINANCIAL STATEMENTS--(CONTINUED) (Unaudited with respect to June 30, 1996 and 1997 and for each six month period then ended) The net operating loss carryforwards and temporary differences, arising primarily from noncash compensation expense, result in a noncurrent deferred tax benefit at December 31, 1996 and June 30, 1997 of approximately $877,000 and $1,274,000, respectively. In consideration of the Company's accumulated losses and the uncertainty of its ability to utilize this deferred tax benefit in the future, the Company has recorded a valuation allowance of an equal amount on such dates to fully offset the deferred tax benefit amount. For the year ended December 31, 1996 and the six months ended June 30, 1997, 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. 6. RELATED PARTIES Consulting agreements The Company has entered into a consulting agreement, expiring January 15, 1998, with CSO Ventures LLC ("CSO") under which CSO provides the Company with business development, operations and other advisory services. Pursuant to the agreement CSO is paid an annual consulting fee of $120,000. Two Executive Vice Presidents of the Company are principals of CSO. The agreement is only cancelable by the Company for cause, as defined in the agreement. During the year ended December 31, 1996 and the six months ended June 30, 1997, the Company incurred expense of $120,000 and $60,000, respectively, pursuant to the agreement. In connection with the development of its licensed technologies the Company has entered into a consulting agreement with the scientist who developed such technologies, under which the consultant serves as the Company's Chief Scientific Advisor. The scientist, who is a stockholder, shall be paid an annual consulting fee of $75,000. The agreement, which commenced in January 1996 and is only cancelable by the Company for cause, as defined in the agreement, has an initial term of two years and provides for automatic renewals of three additional one year periods unless either party notifies the other of its intention not to renew. Research and development expense incurred under the agreement amounted to $75,000 and $37,500 for the year ended December 31, 1996 and the six month period ended June 30, 1997, respectively. During the year ended December 31, 1996, the scientist was issued warrants to purchase 150,000 shares of the Company's common stock at an exercise price of $1.50 per share (see Note 4). Employment agreements The Company has employment agreements, expiring in December 1998, with its two Executive Vice Presidents ("EVPs"), who are principal shareholders of the Company and CSO, under which the EVPs are each to be paid minimum annual compensation of $150,000. In addition, the Company granted each of the EVPs options to purchase 16,667 shares of the Company's common stock, at an exercise price of $1.50 per share, upon execution of the respective agreements. During the term of the agreements the EVPs are each to receive annual stock option grants to purchase 16,667 common shares exercisable at the fair market value at the date of grant. Under the provisions of the agreements the EVPs will each receive a cash payment equal to 1.5% of the total consideration received by the Company in a transaction resulting in a greater than 50% change in ownership of the outstanding common stock of the Company. The Company incurred $324,000 and $156,000 of expense for the year ended December 31, 1996 and the six months ended June 30, 1997, respectively, pursuant to these agreements. Underwriting agreement As discussed in Note 1, the Company has secured a nonbinding letter of intent with an underwriter to sell shares of the Company's common stock in an IPO. At December 31, 1996 and June 30, 1997, employees of the underwriter hold 594,351 shares or approximately 18% of the Company's outstanding common stock. F-11 SIGA PHARMACEUTICALS, INC. (A DEVELOPMENT STAGE COMPANY) NOTES TO FINANCIAL STATEMENTS--(CONTINUED) (Unaudited with respect to June 30, 1996 and 1997 and for each six month period then ended) 7. LICENSE AND RESEARCH SUPPORT AGREEMENT In January 1996, the Company entered into a license and research support agreement with third parties. Under the terms of the agreement, the Company has been granted an exclusive world-wide license to make, use and sell products derived from the licensed technologies. In consideration of the license grant the Company is obligated to pay royalties equal to a specified percentage of net sales of products incorporating the licensed technologies. In the event the Company sublicenses any technologies covered by the agreement the third parties would be entitled to a significant percentage of the sublicense revenue received by the Company. In addition, the Company is required to make milestone payments, up to $225,000 per product, for each product developed from the licensed technologies. The Company has agreed to sponsor further research by the third parties for the development of the licensed technologies for a period of two years from the date of the agreement, in return for a payment of $725,000 to such third parties. The period of sponsored research will automatically be renewed for additional one-year periods unless terminated by the Company. Amortization of prepaid sponsored research under this agreement was $332,292 and $181,250 for the year ended December 31, 1996 and the six months ended June 30, 1997, respectively. The Company also agreed to reimburse the third parties for costs associated with the preparation, filing and prosecution of patent rights for the licensed technologies incurred prior to the execution of the license and research support agreement. The agreement is only cancelable by the Company for cause, as defined in the agreement. The Company has expensed $310,986 of reimbursable patent preparation costs pursuant to the agreement during the year ended December 31, 1996, of which $66,437 remains accrued at December 31, 1996 and June 30, 1997. In January 1996, the Company entered into research agreements with third parties. Under the terms of the agreements, the Company has agreed to fund two years of research in return for annual payments of $183,320. Research and development expense under these agreements amounted to $175,024 and $91,661 for the year ended December 31, 1996 and the six months ended June 30, 1997, respectively. 8. COMMITMENTS AND CONTINGENCIES Employment agreements The Company has an employment agreement with its Director of Bacterial Research which expires in December 1997. Under the terms of the agreement, the employee is to receive minimum annual compensation of $90,000. The agreement is only cancelable by the Company for cause, as defined in the agreement. During the year ended December 31, 1996 and the six months ended June 30, 1997, the Company incurred $90,000 and $45,000, respectively, of expense pursuant to the agreement. In November 1996, the Company entered into an employment agreement, expiring in November 1999, with its President and Chief Executive Officer. Under the terms of the agreement, the employee is to receive annual base compensation of $225,000 and options to purchase 16,667 shares of the Company's common stock, exercisable at the fair market value on the date of grant.

Under the provisions of the agreement, the President will receive a cash payment equal to 1.5% of the total consideration received by the Company in a transaction resulting in a greater than 50% change in ownership of the outstanding common stock of the Company. During the year ended December 31, 1996 and the six months ended June 30, 1997, the Company incurred $28,435 and $112,500, respectively, of expense pursuant to the agreement.

SUBSEQUENT EVENTS (UNAUDITED) In January and February 1997, in contemplation of its proposed IPO, the Company issued bridge notes (the "Bridge Notes") in the principal amount of $1,000,000. The Bridge Notes bear interest at 10% per annum and are due and payable together with accrued but unpaid interest, on the earlier of (a) the closing of an initial public offering of the Company's common stock, or (b) six months after the date of execution of the Bridge Notes. In conjunction with the issuance of the Bridge Notes, the Company entered into warrant agreements whereby to the purchasers of the Bridge Notes will be issued warrants to purchase a number of shares of common stock determined by dividing (i) one-half of the gross proceeds of the Bridge Notes ($500,000) by (ii) the IPO price per share. The warrants will provide for an exercise price per share equal to the IPO price per share and will not be exercisable until the first anniversary of the date of the consummation of the IPO (or February 28, 1998 if the IPO is not consummated). In the event that prior to the maturity date of the Bridge Notes (i) the Company's proposed IPO is not consummated, or (ii) the Company is acquired by another corporation, the holders of the Bridge Notes will receive warrants to purchase an aggregate of 100,000 shares of common stock at an exercise price of $5.00 per share. As of August 28, 1997, the maturity date of Bridge Notes in the principal amount of $1,000,000, which had original maturity dates of July and August 1997, had been extended to the earlier of October 1, 1997 or completion of the IPO. The fair value of the warrants, in the amount of $133,000, issued by the Company in connection with the bridge financing, has been recorded as debt discount and is being amortized over the six month term of the Bridge Notes. During the period ended June 30, 1997 the Company recognized $88,667 of debt discount amortization as interest expense. Upon completion of the Company's planned IPO and repayment of the Bridge Notes from the net proceeds of the offering, the unamortized portion of the debt discount will be immediately expensed. In July 1997, the Company entered into a collaborative research and license agreement with a large pharmaceutical company. Under the terms of the agreement, the Company has granted the pharmaceutical company an exclusive worldwide license to develop, make, use and sell products derived from specified technologies. The agreement requires the pharmaceutical company to sponsor further research by the Company for the development of the licensed technologies for a period of two years from the effective date of the agreement, in return for payments to the Company totaling $1,200,000. In consideration of the license grant the Company is entitled to receive royalties equal to specified percentages of net sales of products incorporating the licensed technologies. The royalty percentages increase as certain cumulative and annual net sales amounts are attained. The Company could receive milestone payments, under the terms of the agreement of up to $13,750,000 for the initial product and up to $3,250,000 for the second product developed from a single compound derived from licensed technologies. The Company could also receive, under certain circumstances additional milestone payments for an additional compound, as defined in the agreement, developed from the licensed technologies. Such milestone payments are contingent upon the Company making project milestones set forth in the agreements, and, accordingly, if the Company is unable to make such milestones, the Company will not receive such milestone payments. In July 1997, the Company entered into a non-binding letter of intent with a third party pursuant to which the Company will acquire the third party's rights to certain technology, intellectual property and related rights in the field of gram negative antibiotics in exchange for 335,530 shares of the Company's common stock. There can be no assurance that the Company will enter into a final agreement with the third party on the terms described above or at all.
