It may not contain all of the information important to you. To understand this offering fully and get a better understanding of our business and operations, you should read the entire prospectus carefully, including the risk factors and the documents we have incorporated by reference in the section "Where You Can Find More Information About Us." Please note that references in this prospectus to "we", "our" or "us" refer to American Biogenetic Sciences, Inc. and our subsidiary, Stellar Bio Systems, Inc., not to the selling stockholder. GENERAL INFORMATION ABOUT AMERICAN BIOGENETIC SCIENCES, INC. We are engaged in researching, developing and marketing cardiovascular and neurobiology products for commercial development. We commenced selling our products during the last quarter of 1997. Some of our products are designed to be used for IN VIVO, while others are designed for IN VITRO, diagnostic procedures. IN VIVO diagnostic procedures are those in which proteins or compounds are injected directly into the body or bloodstream to assess abnormal reactions or conditions. During IN VITRO procedures, blood, urine or other bodily fluid or tissue is extracted from the body and the diagnostic tests are performed in a test tube or other laboratory equipment. Our main products are: o Thrombus Precursor Protein test, referred to as the TpP(TM) test. This is an IN VITRO diagnostic test used to assess the risk of blood clots in the veins or arteries. This test is also used to monitor the performance of anti-clotting therapy or drugs used in the prevention of blood clots. o Functional Intact Fibrinogen test, referred to as the FiF(R) test. This is an IN VITRO diagnostic test which measures the levels of fibrinogen in blood. Fibrinogen is a protein used in the blood-clotting process. o Therapeutic neurocompounds. These are chemical compounds that have been identified for the treatment of epilepsy, migraine and mania and other diseases of the nervous system. o IN VITRO diagnostic products for infectious and auto-immune diseases. These products can determine the status of diseases such as human herpes and lupus. o Mouse serum. This serum is a blood component that lacks blood cells. IN VITRO diagnostic product manufacturers use it in diagnostic tests for various purposes. The company was incorporated in Delaware in September 1983. Our principal executive offices are located at 1375 Akron Street, Copiague, New York 11726, and our telephone number at that address is (631) 789-2600. As of April 20, 2000, we had 40,507,028 shares of Class A common stock and 3,000,000 shares of Class B common stock outstanding. As of that date, we also had 7,000 share of Series A preferred stock outstanding, which were immediately convertible into 7,000,000 shares of our Class A common stock. This prospectus relates to 650,000 shares of our Class A common stock that may be issued upon exercise of certain outstanding warrants. 5 RISK FACTORS BEFORE YOU BUY SHARES OF OUR CLASS A COMMON STOCK, YOU SHOULD BE AWARE THAT THERE ARE VARIOUS RISKS ASSOCIATED WITH THAT PURCHASE, INCLUDING THOSE DESCRIBED BELOW. YOU SHOULD CONSIDER CAREFULLY THESE RISK FACTORS, TOGETHER WITH ALL OF THE OTHER INFORMATION IN THIS PROSPECTUS AND THE DOCUMENTS WE HAVE INCORPORATED BY REFERENCE IN THE SECTION "WHERE YOU CAN FIND MORE INFORMATION ABOUT US" BEFORE YOU DECIDE TO PURCHASE SHARES OF OUR CLASS A COMMON STOCK. RISKS ASSOCIATED WITH OUR LACK OF OPERATING HISTORY, HISTORY OF LOSSES AND FUTURE NEED FOR CAPITAL OUR LACK OF SIGNIFICANT REVENUES FROM PRODUCT SALES AFFECTS OUR ABILITY TO GENERATE CASH We are a development stage company. Although we have products at various stages of development and have started to generate revenues, we may not generate significant revenues from product sales to advance beyond the development stage. Through December 31, 1999, we have received an aggregate of $1,384,000 in licensing fees, royalties and fees under collaborative agreements. Sales of the TpP and FiF tests and sales of Stellar's products since its acquisition on April 23, 1998, totaled $2,708,000 through December 31, 1999. WE HAVE A HISTORY OF LOSSES, AND IF WE DO NOT ACHIEVE PROFITABILITY, WE MAY NOT BE ABLE TO CONTINUE OUR BUSINESS IN THE FUTURE Our research, development, and general and administrative expenses have resulted in significant losses in each year since our inception in 1983 and are expected to continue to result in significant losses for the foreseeable future. We have incurred the following losses since 1995: Fiscal year ended: o December 31, 1995..................... $5,607,000 o December 31, 1996..................... $7,700,000 o December 31, 1997..................... $7,147,000 o December 31, 1998..................... $7,548,000 o December 31, 1999..................... $5,351,000 THE CYCLE FROM PRODUCT DEVELOPMENT TO COMMERCIALIZATION IS LENGTHY AND MAY RESULT IN DELAYS IN THE COMMERCIALIZATION OF OUR PRODUCTS Our existing products and our products under development are subject to the risks inherent in the development of most biotechnology products. We are unable to predict with any degree of certainty when, or if, we will complete the research, development and testing of products currently under development and future products or, if completed, whether we will obtain required regulatory approvals. In addition, we may not be able to produce our products in commercial quantities at reasonable costs, and our products may not be accepted by the medical community. WE COULD BE REQUIRED TO CUT BACK OR STOP OPERATIONS IF WE ARE UNABLE TO RAISE OR OBTAIN NEEDED FINANCING The research, development, commercialization, manufacturing and marketing of our products will require financial resources that are significantly in excess of those presently available to us. We probably will need to seek additional financing, which may result in (1) borrowings that could affect our results of operations and create an obligation to repay loans and (2) the issuance of additional shares of our capital stock and/or rights to acquire additional shares of our capital stock. Such additional issuances of capital would result in a reduction of your percentage interest in our company. We may not be able to arrange financing or other third party arrangements necessary to fully develop and commercialize any of our products on acceptable terms or at all. 2 6 RISKS ASSOCIATED WITH THE INDUSTRY IN WHICH WE OPERATE IF WE DO NOT OBTAIN AND MAINTAIN NECESSARY U.S. OR FOREIGN CLEARANCES OR MANUFACTURING AND MARKETING APPROVALS FOR OUR PRODUCTS, OUR BUSINESS AND OPERATIONS COULD BE ADVERSELY AFFECTED The investigation, manufacture, exportation, marketing and sale of diagnostic and therapeutic products in or from the United States is subject to regulation by the Food and Drug Administration, as well as by comparable foreign and state agencies. Although we have obtained pre-market clearance for some of our existing products, other products may not be approved by the FDA or other applicable foreign regulatory agencies. Any FDA, foreign and state regulatory approvals or clearances, once obtained, can be withdrawn or modified. Our inability to obtain and maintain any necessary United States or foreign clearances or manufacturing and marketing approvals for our products could have a material adverse effect on our business, financial condition and results of operations. In addition, our failure to comply with applicable government requirements could result in, among other things, fines, injunctions, civil penalties, recall or seizure of products, total or partial suspension of production, failure of the government to grant pre-market clearance or pre-market approval for those products, withdrawal of marketing or manufacturing approvals, and criminal prosecutions. WE MAY HAVE TO LOWER PRICES OR SPEND MORE MONEY TO EFFECTIVELY COMPETE AGAINST COMPANIES WITH GREATER RESOURCES THAN OURS, WHICH COULD RESULT IN LOWER REVENUES AND/OR PROFITS The biotechnology industry is characterized by rapid technological advances, evolving industry standards and technological obsolescence. While our TpP is a unique diagnostic test that measures the beginning stages of active clot formation, a feature which we believe has competitive advantages, this product faces competition from other diagnostic tests that measure blood clots during the breakdown stage after the blood clot has formed or that measure other clotting factors that assess the risk of future clots. Our FiF test faces competition from several other fibrinogen tests. Most of our competitors have financial resources and research and development staffs and facilities substantially greater than ours. We may not be able to compete successfully given this competitive environment. For example, if our competitors offer lower prices, we could be forced to lower our prices, which would result in reduced margins and may affect our revenues if we do not compensate for the reduced margins by increasing our sales volume. On the other hand, if we do not lower our prices with our competitors, we could lose sales and market share. In either case, if we are unable to compete against companies that can afford to cut prices, we would not be able to generate sufficient revenues to grow the company or reverse our history of losses. In addition, our competitors and others may develop products that may render our products obsolete or that have advantages over our products, such as greater accuracy and precision or greater acceptance by the medical community. Competing products may also get through the regulatory approval process sooner than our products, enabling our competitors to market their products earlier than we can. Usually, the first person to market a product has a significant marketplace advantage. In addition, other products now in use, presently undergoing the regulatory approval process or under development by others may perform functions similar to those of our existing products or products that we have under development. A LACK OF ACCEPTANCE OF OUR PRODUCTS BY THE MEDICAL COMMUNITY COULD RESULT IN LOWER REVENUES The commercial success of our products is substantially dependent on acceptance and use of our products by the medical community. Our products may not be accepted by the medical community, or it may take a lengthy period of time to gain the necessary acceptance. Widespread acceptance of our products as useful additional tools for diagnosis and treatment will require educating the medical community about the products' benefits, reliability and effectiveness. In addition, the existence or development of competing products, which may be as or more effective than our products for a specific use, may adversely affect acceptance of our products. WE MAY HAVE INCREASED EXPENSES IF OUR MARKETING EFFORTS ARE NOT SUCCESSFUL Our strategy is to seek arrangements with large pharmaceutical companies to market our products. In the event we are unable to enter into those arrangements in the future, or if our arrangements are not successful, we may seek to market our products through independent distributors or through sales representatives. Independent 3 7 distributors may require us to develop a marketing program to support sales. In that event, we may incur additional expenses for the development of promotional literature and aides, promotional activities, the hiring of sales representatives and the conduct of additional studies in order to promote the interests of distributors in our products. We may not be able to develop those marketing arrangements on satisfactory terms, and we may not have the working capital necessary to establish the sales support generally required by independent distributors. RISKS ASSOCIATED WITH OUR INTERNAL OPERATIONS AND POLICIES SINCE WE DO NOT INTEND TO DECLARE DIVIDENDS IN THE FORESEEABLE FUTURE, THE RETURN ON YOUR INVESTMENT WILL DEPEND UPON APPRECIATION OF THE MARKET PRICE OF YOUR SHARES Our board of directors does not intend to declare any dividends in the foreseeable future, but intends to retain all earnings, if any, for use in our business operations. As a result, your return on your investment in our company will depend upon the appreciation, if any, in the market price of our common stock. The holders of our Series A preferred stock and our Class A and Class B common stock are entitled to receive dividends when, as and if declared by the board of directors out of funds legally available for dividend payments. To date, we have not paid any cash dividends. The payment of dividends, if any, in the future is within the discretion of our board of directors and will depend upon our earnings, capital requirements and financial condition, and other relevant factors. THE LOSS OF THE SERVICES OF MR. ROACH OR MR. NORTH COULD ADVERSELY AFFECT OUR BUSINESS AND PROSPECTS AND OUR ABILITY TO RECRUIT OR RETAIN QUALIFIED PERSONNEL Our success may depend upon the efforts of (1) Alfred J. Roach, the Chairman of our board of directors and one of our major stockholders, and (2) Mr. John S. North, our President and Chief Executive Officer. Mr. Roach is not subject to any employment agreement. Our employment agreement with Mr. North expires on November 15, 2001. Each of these executives is subject to earlier termination in certain cases. We do not maintain life insurance on the lives of Mr. Roach or Mr. North. The loss of the services of Mr. Roach or Mr. North could adversely affect our business and prospects. In addition, because of the nature of our business, our success depends upon our ability to attract and retain technologically qualified personnel, particularly research scientists. There is substantial competition for qualified personnel, including competition from companies with substantially greater resources than ours. We may not be successful in recruiting or retaining personnel of the requisite caliber or in adequate numbers to enable us to conduct our business and effectively compete in our industry, and the loss of Mr. Roach or Mr. North could make recruitment and retention even more difficult. RISKS WHICH MAY DILUTE THE VALUE OF YOUR SHARES OF OUR COMMON STOCK OR LIMIT THE EFFECT OF YOUR VOTING POWER OUR COMMON STOCK IS ONLY TRADED ON THE OVER-THE-COUNTER MARKET, AND NASDAQ MAY DENY OUR REQUEST FOR REINSTATEMENT ON THE NASDAQ SMALLCAP MARKET, WHICH COULD NEGATIVELY AFFECT THE PRICE AND LIQUIDITY OF THE COMMON STOCK On January 6, 2000, the Nasdaq Stock Market, Inc. delisted our Class A common stock from the Nasdaq SmallCap Market. Our Class A common stock currently trades on the OTC Bulletin Board. We have requested review of the delisting decision, and we are seeking reinstatement on the Nasdaq NationalSmallCap Market. If we fail to obtain reinstatement of our Nasdaq SmallCap Market was $.78125. Becauselisting, the market value of our Class A common stock could decline, certain regulatory rules will apply, and stockholders may find it more difficult to dispose of their shares. THE PRICE OF OUR COMMON STOCK IS HIGHLY VOLATILE The price of our Class A common stock is highly volatile. During the period from January 1, 1999 to April 20, 2000, the closing bid price of our Class A common stock has ranged from a high of $6.41 in March 2000 to a low of $0.25 in September 1999. We believe that the volatile fluctuations of the market price are based on a number of factors, including (1) the number of shares in the market at the time as well as the number of shares we may be required to issue in the future, compared to the market demand for our shares; (2) our performance, including the 4 8 development and commercialization of our products and proposed products; and (3) general economic and market conditions. Following periods of volatility in the market price of a company's securities, securities class action lawsuits have often been instituted against such a company. If similar litigation were instituted against us, it could result in substantial costs and a diversion of our management's attention and resources, which could have an adverse effect on our business. AMERICAN BIOGENETIC SCIENCES, INC. IS CONTROLLED BY ALFRED J. ROACH, WHO MAY SUBSTANTIALLY DETERMINE THE OUTCOME OF PROPOSALS SUBMITTED TO THE STOCKHOLDERS As of April 20, 2000, Alfred J. Roach, the Chairman of our Board of Directors, owned and had the power to vote all 3,000,000 outstanding shares of our Class B common stock and 4,472,250 shares of our Class A common stock. Each share of Class B common stock is entitled to ten votes, while each share of Class A Common Stock has been below $1.00common stock is entitled to one vote. Accordingly, as of April 20, 2000, Mr. Roach was entitled to cast approximately 48.9% of all votes at meetings of stockholders or by consent without a meeting. As a result, Mr. Roach will be able to exercise significant control over our company through his practical ability to determine the outcome of votes of stockholders regarding, among other things, nomination and certain other factors, we cannot assure you thatelection of directors and approval of significant transactions. Mr. Roach's holdings could increase in the future through conversion of his 1,000 shares of Series A preferred stock into 1,000,000 shares of Class A common stock, and through his exercise of options and warrants to purchase an additional 2,410,000 shares of our Class A Common Stock will continuecommon stock, which he may exercise at any time. WE HAVE A SUBSTANTIAL NUMBER OF SHARES RESERVED FOR FUTURE ISSUANCE WHICH, WHEN ISSUED, WILL REDUCE YOUR PERCENTAGE OF OWNERSHIP AND VOTING POWER AND MAY AFFECT THE PRICE OF YOUR SHARES OF OUR COMMON STOCK The issuance of a significant number of shares of stock would dilute the percentage ownership of existing stockholders and could have a significant adverse effect on the market price of our Class A common stock. As of April 20, 2000, we had outstanding 40,507,028 shares of Class A common stock. On that date, we had an additional 24,768,340 shares of Class A common stock reserved for possible future issuance upon conversion of our Class B common stock and Series A preferred stock and upon exercise of outstanding options and warrants, including the 650,000 shares of Class A common stock covered by this prospectus. In addition, we may in the future seek additional financing, which may result in the issuance of additional shares of our capital stock and/or rights to be quoted on Nasdaq. See "Risk Factors - No Assuranceacquire additional shares of Continued Nasdaq Listing," on page 5. ------------------------ This investment involves a high degreeour capital stock.

It may not contain all of the information important to you. To understand this offering fully10 You can review and get a better understanding of our business and operations, you should read the entire Prospectus carefully, including the risk factors, and the documents we have incorporated by reference in the section "Where You Can Find More Information About Us." Please note that references in this Prospectus to "we," "our" or "us" refer to American Biogenetic Sciences, Inc. and our subsidiary, Stellar Bio Systems, Inc., not to the Selling Stockholders. The Company We are engaged in researching, developing and marketing cardiovascular and neurobiology products for commercial development. Product sales began during the last quarter of 1997. Certain of our products are designed to be used for in vivo, while others are designed for in vitro, diagnostic procedures. In vivo diagnostic procedures are those in which certain cells or organisms are injected directly into the body or bloodstream to assess a particular reaction of the living cells. During in vitro procedures, blood or tissue is extracted from the body and the diagnostic tests are performed in a test tube or other laboratory equipment. Our products include: o Thrombus Precursor Protein (TpP(TM)) test. This is an in vitro diagnostic test used to assess the risk of active thrombosis (blood clots) in the veins or arteries. This test is also used to monitor the performance of anticoagulent (anti-clotting) therapy or drugs used in the prevention of blood clots. o Functional Intact Fibrinogen (FiF(TM)) test. This is an in vitro diagnostic test which measures the levels of fibrinogen in blood. Fibrinogen is a protein used in the blood-clotting process. These tests assist doctors in diagnosing and treating blood clots lodged deeply in the legs (known as DVT- deep vein thrombosis) and blood clots in the lungs (known as PE - pulmonary embolisms). Deep vein thrombosis can move to the lungs and cause pulmonary embolisms, which can be fatal. Thrombosis is also associated with many other medical conditions, such as heart attacks, strokes and complicated pregnancies. The Company is pursuing the application of its tests in these areas with additional clinical testing. We have also developed patented monoclonal antibodies called MH1 and 45J which we use in our TpP(TM) test. The 45J monoclonal antibody is also used in our FIF(TM) test. Antibodies are produced in response to substances which are recognized as foreign by the host. Our antibodies MH1 and 45J were developed using our patented antigen-free mouse colony. We are evaluating the use of MH1 as an in vivo imaging agent. In this process, a radioisotope is attached to MH1 which emits a signal enabling instruments to detect where a thrombolytic (blood clot) event has occurred within the body. We have completed the United States Food and Drug Administration's Phase I/II studies for the use of the MH1 with a radioisotope as an imaging agent. We must still complete the FDA's Phase II and Phase III studies. Our products require approval from the FDA prior to marketing in the United States. Some in vitro diagnostic products are eligible for an accelerated FDA application process in accordance with Section 510(k) of the 1976 Medical Device Amendments to the Federal Food, Drug and Cosmetic Act as a product "substantially equivalent" to another product in commercial distribution in the United States before May 28, 1976. To date, we have received Section 510(k) Pre-Market Clearance from the FDA for our TpP(TM) and FiF(TM) tests. In November 1997, we commenced marketing efforts for the TpP(TM) and FiF(TM) tests. On April 23, 1998, we purchased all of the issued and outstanding shares of common stock of Stellar Bio Systems, Inc., a manufacturer and distributor of in vitro diagnostic products and research reagents used in - 3 - the biotechnology industry. Stellar's in vitro diagnostic products focus on the infectious disease and auto-immune disease markets. Stellar markets a complete line of products to determine the immune status of numerous human herpes viruses. In addition, auto-immune diseases, such as lupus, are detected using Stellar's products. Stellar is also the largest domestic provider of normal mouse serum, which is used as a test component by major in vitro diagnostic product manufacturers for a variety of purposes. Our company was incorporated in Delaware in September 1983. Our principal executive offices are located at 1375 Akron Street, Copiague, New York 11726, and our telephone number at that address is (516) 789-2600. The Offering Class A Common Stock being offered by the Selling Stockholders........ 10,800,000 Shares Class A Common Stock outstanding after this offering................... 35,559,556 Shares Nasdaq/NMS Symbol........................ MABXA Use of Proceeds.......................... The Selling Stockholders will receive all net proceeds from the sale of the Shares. Accordingly, we will not receive any proceeds from the resale of the Shares. We received $2,700,000 in proceeds from our sale of the Shares to the Selling Stockholders. We used such funds, together with other funds in our treasury, to repurchase the remaining 5% Convertible Debentures and outstanding Warrants issued in a private placement in May 1998. We have agreed to bear customary expenses incident tocopy the registration of the Shares for the benefit of the Selling Stockholders, other than discountsstatement, its exhibits and commissions. Risk Factors............................. The securities offered hereby involve a high degree of risk. You should carefully consider the factors described under the caption "risk factors." - 4 - RISK FACTORS Before you buy shares of our Class A Common Stock, you should be aware that there are various risks associated with such purchase, including those described below. You should consider carefully these risk factors, together with all of the other information in this Prospectus, and the documents we have incorporated by reference in the section "Where You Can Find More Information About Us" before you decide to purchase shares of our Class A Common Stock. Some of the information in this Prospectus and in the documents we have incorporated by reference, may contain forward-looking statements. Such statements can be generally identified by the use of forward-looking words such as "may," "will," "expect," "anticipate," "intend," "estimate," "continue," "believe," or other similar words. These statements discuss future expectations, or state other "forward-looking" information. When considering such statements, you should keep in mind the risk factors and other cautionary statements in this Prospectus. The risk factors noted in this section and other factors noted in this Prospectus could cause our actual results to differ materially from those contained in any forward-looking statements. Development Stage Company. The Company remains in the development stage. We have not generated significant revenues from product sales from our inception through September 30, 1998 and have incurred losses every year since our formation in 1983. Through September 30, 1998, we have received an aggregate of $1,302,000 in licensing fees, royalties and under collaborative agreements. Sales of the TpP(TM) and FIF(TM) tests, which commenced during the fourth quarter of 1997, and sales of Stellar's products since its acquisition on April 23, 1998, have totaled $1,003,000 through September 30, 1998. While we have products at various stages of development and have started to generate revenues, we cannot assure you as to if and when we may begin generating significant revenues from product sales and cease being a development stage company. History and Expectation of Future Losses; Accumulated Deficit. Our research, development, and general and administrative expenses have resulted in significant losses and are expected to continue to result in significant losses for the foreseeable future. We have incurred the following losses since 1994: Fiscal year ended: o December 31, 1994..................... $7,431,000 o December 31, 1995..................... $5,607,000 o December 31, 1996..................... $7,700,000 o December 31, 1997..................... $7,147,000 Nine months ended: o September 30, 1998.................... $4,572,000 At September 30, 1998, we had net worth of $4,949,000, with an accumulated retained earnings deficit of $53,987,000. We had $5,695,000 in cash and cash equivalents at September 30, 1998. We expect to continue to have losses in the near future. Our future profitability is dependent, in part, on our ability to: o successfully market our existing products and complete products under development, o obtain required regulatory approvals and manufacture and market successfully such products directly or through partners, and o acquire products which can be successfully marketed. - 5 - No Assurance of Continued Nasdaq Listing. Our Class A Common Stock is currently quoted on The Nasdaq National Market. On February 23, 1998, Nasdaq adopted new requirements which issuers are required to meet in order to maintain their listings. On September 24, 1998, Nasdaq issued a letter indicating that our Class A Common would be delisted as of December 28, 1998 unless we complied with the minimum bid requirement of $1 for a period of ten consecutive trading days. This requirement applies to a listing on both Nasdaq's National Market and SmallCap Market. We provided data to Nasdaq which shows that our Class A Common Stock met the $1 minimum bid requirement on each of the twelve consecutive trading days from November 11, 1998 to November 27, 1998. Nevertheless, the Staff of Nasdaq has advised us that it still intends to delist our Class A Common Stock. We have appealed the delisting decision by requesting a hearing before an Appeals Panel. The delisting has been stayed until after the hearing has been held. To date, no hearing date has been set. Our stockholders have authorized our Board of Directors to implement a reverse split of our Class A and Class B Common Stock within a range of one new share to be issued for each four to eight presently outstanding shares. We may be required to implement a reverse split in order to maintain a Nasdaq listing of our Class A Common Stock. We are also required to maintain net tangible assets of at least $4,000,000 for Nasdaq National Market, but may only need $2,000,000 to be traded on the Nasdaq SmallCap Market. Net tangible assets is total assets (excluding goodwill) minus total liabilities. At September 30, 1998, our net tangible assets were approximately $4,463,000. We cannot assure you that our Class A Common Stock will continue to be quoted on Nasdaq. If we fail to maintain a Nasdaq listing, our securities will likely be traded on the OTC Bulletin Board. As a result, the market value of our Class A Common Stock could decline and stockholders may find it more difficult to dispose of, or to obtain accurate quotations as to the market value of, our Class A Common Stock. Unproven Products. Although we have had recent sales of our TpP(TM) and FiF(TM) kits and products acquired as part of the acquisition of Stellar, our existing products and our products under development are subject to the risks inherent in the development of biotechnology products. In order to finalize these and other future products for sale, we must complete further research, development and testing and obtain regulatory clearance. In addition, we must calculate the costs of large scale manufacturing before any products can deemed to be commercially viable. We are unable to predict with any degree of certainty when, or if, we will complete the research, development and testing of products under development and other future products, or if completed, whether we will obtain required regulatory approvals. In addition, we cannot assure you that once our products are developed, tested and approved, that we will be able to produce our products in commercial quantities at reasonable costs, that our products will be acceptable to the medical community, or that our marketing and sales efforts will be successful. Risks in Developing Our Proposed Products Our operations are subject to numerous risks associated with the development of pharmaceutical products, including the competitive and regulatory environment in which we operate. In addition, we may encounter unanticipated problems, including development, manufacturing, distribution and marketing difficulties, some of which may be beyond our financial and technical abilities to resolve. Accordingly, we cannot assure you that our products will prove to be commercially viable, or that we will successfully market any products or achieve significant revenues or profitable operations. - 6 - Need For Additional Financing. The research, development, commercialization, manufacturing and marketing of our products will likely require financial resources significantly in excess of those presently available to us. We intend to seek additional financing which may result in (1) borrowings that could affect our results of operations and create an obligation to repay the loans and (2) the issuance of additional shares of our capital stock and/or rights to acquire additional shares of our capital stock. Such additional issuances of capital would result in a reduction of your percentage interest in the Company. Future issuances could cause dilution of the interests of the then existing stockholders of the Company. We also intend to continue to seek collaborative, licensing, co-marketing or other arrangements with large pharmaceutical companies or other third parties to: o provide additional funding and clinical expertise, o perform clinical trials necessary to obtain regulatory approvals, o provide manufacturing expertise, and o market our products. These arrangements may result in our sharing the benefits (i.e., royalty payments) of our products with such third parties,schedules, as well as sharing with, or relying upon, the management of others fordocuments listed below, at the development, testing and/or marketing of products. We cannot assure you that we will be able to arrange financing, collaborative arrangements or other third party arrangementspublic reference facilities maintained by the SEC as described above. The registration statement, including its exhibits and schedules, are also available on acceptable terms necessary to fully develop and commercialize any of our products. Possible Effects of Acquisition Strategy Part of our growth strategy involves the acquisition of companies and product lines which our management may believe could provide synergisms with our products and operations or otherwise facilitate our growth. In April 1998, we acquiredSEC's web site. USE OF PROCEEDS The selling stockholder is selling all of the issued and outstanding shares of common stock of Stellar Bio Systems, Inc., a manufacturer and distributor of diagnostic products and research reagents. In exchange for the shares of Stellar, we paid $120,000 in cash and issued 398,406 shares of our Class A Common Stock ($700,000 at then market value). We also agreed to a contingent future payment of up to $650,000 in shares of our Class A Common Stock. The number of shares we may have to issue depends on the level of Stellar's future revenues and the market price of our Class A Common Stock at approximately the date of issuance. To date, the acquisition of Stellar has been our only acquisition. Any future acquisition may require us to borrow or result in the sale or issuance of debt or equity securities to private sources or in public markets. The issuance of any debt could result in the incurrence of significant interest expense and an obligation to repay such debt. The issuance of equity could result in substantial dilution in the equity interest of existing stockholders. Although we are currently engaged in various stages of discussions with regard to potential acquisitions, we are not presently a party to any commitment with respect to any acquisition. We cannot assure you that (1) we will be successful in identifying or consummating acquisitions on favorable terms, if at all, or in integrating the operations of Stellar or future acquisitions, or (2) that any businesses we acquire will achieve sales and profitability that justify our investment. - 7 - Integration of Acquisitions. The success of any acquisition will depend in large measure on our ability to effectively integrate the operations, management and information systems of the businesses we acquire. The process of integrating acquired businesses often involves unforeseen difficulties and may require us to devote a significant amount of our financial and other resources to such projects. Acquisitions may also involve a number of additional risks, such as adverse short-term effects on earnings, diversion of management's attention, unanticipated problems or legal liabilities, and amortization expense for the amount of the purchase price paid for acquired assets in excess of their fair value. Some or all of such factors could have a material adverse effect on our business, financial condition and results of operations. In addition, to the extent that agreements relating to our acquisitions provide for reimbursement to us with respect to contingent and other liabilities of the acquired business, the reimbursement obligations may be, and in the case of the acquisition of Stellar are, only available for a limited period of time and are subject to negotiated limitations. Our business, financial condition and results of operations could be materially and adversely effected if any future claims or liabilities which we may have relating to acquisitions are not subject to any reimbursement obligations, or if the amount of claims or liabilities exceeds the limitations or the ability of the sellers of the acquired entities to satisfy their reimbursement obligations. Certain Effects of Government Regulation. The investigation, manufacture, exportation, marketing and sale of diagnostic and therapeutic products and vaccines in or from the United States is subject to regulation by the Food and Drug Administration, as well as by comparable foreign and state agencies. Noncompliance with applicable requirements can result in, among other things, fines, injunctions, civil penalties, recall or seizure of products, total or partial suspension of production, failure of the government to grant pre-market clearance or pre-market approval for devices, withdrawal of marketing or manufacturing approvals, and criminal prosecutions. Some in vitro diagnostic products are eligible for an accelerated application process in accordance with Section 510(k) of the 1976 Medical Device Amendments to the Federal Food, Drug and Cosmetic Act as a product "substantially equivalent" to another product in commercial distribution in the United States before May 28, 1976. In October 1996, we received a Section 510(k) Pre-Market Clearance to market our TpP(TM) test as an aid in the risk assessment of thrombosis and the monitoring of anticoagulant therapy. We plan to submit additional pre-market notifications to obtain clearance to market the TpP(TM) test for additional specific uses. In June 1997, we received Section 510(k) Pre-Market Clearance to market our FiF(TM) diagnostic test for the quantitative determination of fibrinogen in human blood. Obtaining FDA approval and complying with FDA regulation with respect to in vivo products (such as certain proposed uses of our MH1 product) is far more expensive and time consuming than the costs associated with the review of products for in vitro use. Therefore, we intend to seek joint ventures or licensing arrangements with respect to our in vivo products in order to share the costs associated with the regulatory review and/or approval process. We cannot provide any assurance that we will be able to enter into any such arrangements or that the terms of such agreement will be favorable to us. Although we have obtained Pre-Market Clearance for some of our existing products, we cannot assure you that any of our future products will be approved by the FDA or other applicable foreign regulatory agency. Any FDA, foreign or state regulatory approvals or clearances, once obtained, can be withdrawn or modified. Our inability to obtain and maintain, any necessary United States or foreign clearances or manufacturing and marketing approvals for our products could have a material adverse effect on our business, financial condition and results of operations. - 8 - Dependence on Acceptance by Medical Community. The commercial success of our products is substantially dependent on acceptance and use of our products by the medical community. Widespread acceptance of our products as useful additional tools to diagnosis and treatment will require educating the medical community about the product's benefits, reliability and effectiveness. In addition, acceptance of our products may be adversely affected by competing products which may be as or more effective than our products for a specific use. Accordingly, we cannot assure you that any of our products will be accepted by the medical community, or, if accepted, as to the length of time it would take to gain such acceptance. Marketing Arrangements or Other Sales Arrangements. It is our strategy to seek arrangements with large pharmaceutical companies to market our products. In the event we are unable to enter into such arrangements in the future or if our arrangements are not successful, we may seek to market our products through independent distributors. Independent distributors may require us to develop a marketing program to support sales. In that event, we may incur additional expenses for the development of promotional literature and aides, the hiring of sales representatives and the completion of studies in order to promote the interests of distributors in our products. We cannot assure you that we will be able to develop such marketing arrangements on satisfactory terms or that, if necessary, we would have the working capital to establish the sales support generally required by independent distributors. Manufacturing Facilities. Although we are presently producing a limited quantity of monoclonal antibodies for testing and evaluation of our in vitro products, we cannot provide any assurance that we will able to either finance or meet FDA regulations for good manufacturing practices required in order to convert and operate our current facility for the commercial production of these products. We do not intend to establish our own manufacturing operations for our in vivo products unless and until, in the opinion of our management, the size and scope of our business and our financial resources so warrant. Currently, we have agreements with manufacturers for the production of each of our antibodies (MH1 and 45J) and our TpP(TM) and FiF(TM) diagnostic kits. We intend to seek additional third parties to manufacture our in vivo monoclonal antibody and other in vivo products, or to enter into a joint venture or license agreement with a partner who will be responsible for future manufacturing. Each joint venture partner or contract manufacturer participating in the manufacturing process of our products must comply with FDA regulations and file documentation with the FDA to support that part of the manufacturing process in which it is involved. We cannot assure you that we will be able to manufacture sufficient quantities of our in vivo monoclonal antibody necessary to obtain full FDA clearance or approval, that the FDA will accept our manufacturing arrangements, or that we will maintain existing commercial manufacturing arrangements or obtain new agreements on acceptable terms. Patents and Protection of Proprietary Information. Our business depends, in part, upon our proprietary technology. We rely on a combination of trade secret laws, patents, trademarks and confidentiality and other contractual agreements to establish, maintain and protect our proprietary rights. However, all afford only limited protection. We hold fifteen U.S. patents for various products and have additional patent applications pending with the United States Patent and Trademark Office. We have also obtained or applied for corresponding patents for certain of the U.S. patents and patent applications in a limited number of foreign countries. - 9 - With respect to certain aspects of our technology, we rely upon trade secrets, unpatented proprietary know-how and continuing technological innovation to protect access to our proprietary information. We have confidentiality and invention assignment agreements with our employees, and generally enter into non-disclosure agreements with our scientific consultants and collaborators. All members of our Scientific Advisory Committee are employed by or have consulting agreements with third parties, whose business may conflict or compete with our business, and any inventions discovered by such individuals will not become our property. We cannot assure you that our pending patent applications will issue as patents, that any issued patent will provide us with significant competitive advantages or that challenges will not be instituted against the validity or enforceability of any of our patents. Because foreign patents may afford less protection under foreign law than is available under U.S. patent law, we cannot assure that any such patents issued to us will adequately protect our proprietary information. In addition, other companies may independently develop similar or more advanced products, design patentable alternatives to our products or duplicate our trade secrets, and our employees and collaborators could breach their confidentiality agreements. Also, we may be required, in some cases, to obtain licenses from third-parties or to redesign our products or processes to avoid infringement. Any litigation by us to seek to protect our intellectual property or against us, would be costly and could divert the efforts and attention of our management and technical personnel, which could have a material adverse effect on our business, financial condition and results of operations. Many of our therapeutic compounds are the subject of patent applications which we license from various academic institutions. Such licenses require us to pay royalties on the sales of products. We cannot assure you that these licensed products will be commercially viable or that the licenses will not be terminated. Competition; Rapid Technological Changes. The biotechnology industry is characterized by rapid technological advances, evolving industry standards and technological obsolescence. Several of our competitors, including large pharmaceutical, chemical, biotechnology and agricultural concerns, universities and other research institutions, have financial resources and research and development staffs and facilities substantially greater than ours. Our competitors may develop products which may render our products obsolete or which have advantages over our products, such as greater accuracy and precision or greater acceptance by the medical community. Competing products may also get through the regulatory approval process sooner than our products, thereby enabling our competitors to market their products earlier than we can. Usually, the first person to market a product has a significant marketplace advantage. In addition, other products now in use, presently undergoing the regulatory approval process, or under development by others, may perform similar functions as our existing products or those under development. Any technical advisory issued by our competitors or our inability to meet and surpass our competitors' technological advances, could have a material adverse effect on our business, financial condition and results of operations. Retention and Attraction of Key Personnel. Our success depends to a significant extent upon the efforts of (1) Alfred J. Roach, the Chairman of our Board of Directors and one of our major stockholders, (2) Mr. John S. North, our President and Chief Executive Officer, and (3) Dr. Emer Leahy, our Senior Vice President-Business Development. Mr. Roach is not subject to any employment agreement. Our employment agreement with Mr. North expires on November 15, 2001 and our employment agreement with Dr. Leahy expires on November 30, 2001. We do not maintain life insurance on the lives of Mr. Roach, Mr. North or Dr. Leahy. The loss of the services of Mr. Roach, Mr. North or Dr. Leahy, as well as certain other personnel, could adversely affect our business and prospects. Because of the nature of our business, our success is dependent upon our ability to attract and retain technologically qualified personnel, particularly research scientists. There is substantial competition for qualified personnel, including competition from companies with substantially greater resources than ours. We cannot assure you that we will be successful in recruiting or retaining personnel of the requisite caliber or in adequate numbers to enable us to conduct our business and effectively compete in our industry. - 10 - Scientific Advisors to the Company. We have a Scientific Advisory Committee which consists of scientific advisors who serve as consultants with respect to the fields of microbiology, immunology and molecular biology and in cardiovascular disease, hepatic disease and drug development. These scientists are employed by or work for others, and they are expected to devote only a small portion of their time to our projects. In addition, these individuals have employment, consulting or other advisory arrangements with other entities. As a result, their obligations to these other entities may conflict or compete with their obligations to us. Regulations, corporate policies or agreements to which these individuals are or may become subject with such other entities may limit the ability of the scientific advisors to continue their relationship with us. Product Liability; Requirement for Insurance Coverage. The testing, marketing and sale of pharmaceutical products carries with it a risk of product liability claims by consumers and others. Instances of negative reactions by the human immune system to mouse derived antibodies, such as those generated from our MH1 antigen-free mouse colony, have been reported. In addition, product and other liability claims may be asserted by physicians, laboratories, hospitals or patients relying upon the results of our diagnostic tests. Claims may also be asserted against us by end users of our products, including persons who may be treated with any in vivo diagnostic or therapeutic products. Certain distributors of pharmaceutical products require minimum product liability insurance coverage as a condition to their purchase of or acceptance of products for distribution. Our failure to satisfy these insurance requirements could diminish our ability to achieve broad distribution of our products which, in turn, would have a material adverse effect upon our business, financial condition and results of operations. We have product liability insurance which covers our TpP(TM) and FiF(TM) products, but do not maintain product liability insurance coverage for our other products. Although we plan to obtain product liability insurance prior to the marketing of any of our proposed products, we cannot assure you that we will be able to secure such insurance or, that if we can obtain insurance, that insurance can be acquired at a reasonable cost or that our existing or future insurance policies will be sufficient to cover all possible liabilities. In the event of any claim or suit against us, lack or insufficiency of insurance coverage could have a material adverse effect on our business, financial condition and results of operations. No Dividends. The holders of Class A and Class B Common Stock are entitled to receive dividends when, as and if declared by the Board of Directors out of funds legally available for dividend payments. To date, we have not paid any cash dividends. The payment of dividends, if any, in the future is within the discretion of our Board of Directors and will depend upon our earnings, capital requirements and financial condition, and other relevant factors. Our Board of Directors does not intend to declare any dividends in the foreseeable future, but intends to retain all earnings, if any, for use in our business operations. Control By Alfred J. Roach. As of December 15, 1998, Alfred J. Roach, the Chairman of our Board of Directors, owned and had the power to vote all 3,000,000 outstanding shares of our Class B Common Stock and 4,035,250 shares of our Class A Common Stock, of which 4,000,000 shares are covered by this Prospectus. Each share of Class B Common Stock is entitled to ten votes, while each share of Class A Common Stock is entitled to one vote. Accordingly, at such date, Mr. Roach was entitled to cast approximately 51.9% of all votes at meetings or by consent without a meeting. As a result, Mr. Roach will be able to exercise significant control over the Company through his ability to determine the outcome of votes of stockholders regarding, among other things, nomination and election of directors and approval of significant transactions. In addition, Mr. Roach holds options to purchase an additional 1,160,000 shares of our Class A Common Stock which he may exercise at any time. - 11 - Dilution; Potential Issuances of Shares. As of December 15, 1998, we had issued and outstanding: o 35,559,556 shares of Class A Common Stock, and o 3,000,000 shares of Class B Common Stock. At that date, there were an additional 9,237,445 shares of Class A Common Stock reserved for possible future issuances as follows: o 3,000,000 shares for issuance upon conversion of the outstanding Class B Common Stock; o 2,790,500 shares for issuance upon the exercise of outstanding options under our 1986 Stock Option Plan. These options are exercisable at prices ranging from $1.50 to $10.00 per share; o 2,000,000 shares for issuance upon the exercise of presently outstanding options or options which may be granted in the future under our 1996 Stock Option Plan. Options to purchase 1,487,750 shares were outstanding at December 15, 1998. These options are exercisable at prices ranging from $0.25 to $5.25 per share; o 487,500 shares for issuance upon the exercise of presently outstanding options or options which may be granted in the future under our 1993 Non-Employee Director Stock Option Plan. Options to purchase 120,000 shares are were outstanding at December 15, 1998. These options are exercisable at prices ranging from $1.00 to $6.75 per share and o 959,445 shares for issuance upon exercise of other outstanding warrants and options held by unaffiliated third parties. These warrants and options are exercisable at prices ranging from $0.75 to $4.25 per share. The issuance of reserved shares would dilute the equity interest of existing stockholders and could have a significant adverse effect on the market price of our Class A Common Stock. See "--Shares Eligible for Future Sale." Shares Eligible For Future Sale. Future sales of substantial amounts of shares in the public market, or the perception that such sales could occur, could adversely affect the market price of our Class A Common Stock. As of December 15, 1998, we had outstanding 38,559,556 shares, consisting of 35,559,556 shares of Class A Common Stock and 3,000,000 shares of Class B Common Stock. Shares of Class B Common Stock are convertible into Class A Common Stock on a share for share basis. Of our outstanding shares, approximately 20,705,368 shares of Class A Common Stock are presently freely transferable without restriction under the Securities Act. Of the remaining 14,854,188 outstanding shares (including the 3,000,000 shares of Class A Common Stock issuable upon conversion of Class B Common Stock): o 10,800,000 are "restricted securities" issued in October 1998; o 600,438 shares are "restricted securities" issued between February 1997 and December 1998; and o 3,453,750 shares are held by persons who may be deemed to be our "affiliates". Of these shares, 1,534,500 are "restricted securities" issued between November 1997 and October 1998. The - 12 - remaining 1,919,250 of such shares are "restricted securities" that were acquired more than two years ago or are not "restricted securities" because they were acquired in the market or pursuant to a registration statement under the Securities Act. In general, an "affiliate" is a person with the power to manage and direct our policies. The SEC has stated that, generally, executive officers and directors of an entity are deemed affiliates of the entity. "Restricted securities" may be (1) sold pursuant to a Prospectus under an effective registration statement under the Securities Act, (2) in compliance with the exemption provisions of Rule 144 or (3) pursuant to another exemption under the Securities Act. Rule 144 permits sales of "restricted securities" by any person (whether or not an affiliate) after one year, at which time sales can be made subject to the Rule's volume and other limitations and after two years by non-affiliates without adhering to Rule 144's volume or other limitations. Shares of our Class A Common Stock owned by our "affiliates" which are not "restricted securities" may be sold at any time by complying with Rule 144's volume and other limitations. We have registered the following under the Securities Act for resale at any time or from time to time: o The 10,800,000 "restricted" shares of Class A Common Stock that are covered by this Prospectus; o 398,406 "restricted" shares of Class A Common Stock issued in April 1998 in consideration for our acquisition of Stellar Bio Systems, Inc.; o 5,000 "restricted" shares of Class A Common Stock issued in June 1996; o 25,000 shares of Class A Common Stock subject to an option held by a former consultant; and o 100,000 shares of Class A Common Stock subject to options held by another former consultant. All of these registered shares will also be freely transferable without restriction under the Securities Act subject to applicable Prospectus delivery requirements. In addition, all shares issuable upon the exercise of options under our stock option plans have been registered under the Securities Act for issuance and, unless held by our "affiliates", will be freely tradable upon issuance. If acquired by our "affiliates," shares issued upon the exercise of those options will not be "restricted securities" and, therefore, could be sold at any time by complying with Rule 144's volume and other limitations. See " - - Dilution; Potential Issuances of Shares." Possible Volatility of Our Stock Price The stock market and the price of our Class A Common Stock may be subject to volatile fluctuations based on general economic and market conditions, as well as our meeting expectations of our performance, including the development and commercialization of our products and proposed products. The price of our Class A Common Stock can also be affected by the number of shares in the market at the time, as well as a perception of such number, including the shares covered by this Prospectus. In addition, stock market volatility has had a significant effect on the market prices of securities issued by many companiesprospectus for reasons unrelated to the operating performance of these companies. In the past, following periods of volatility in the market price of a company's securities, securities class action litigation has often been instituted against such a company. If similar litigation were instituted against us, it could result in substantial costs and a diversion of our management's attention and resources, which could have an adverse effect on our business. Year 2000 Issues Historically, certain computerized systems have used two digits rather than four to define the applicable year. Computer equipment and software and devices with imbedded technology that are time-sensitive may recognize a date using "00" as the year 1900 rather than the year 2000, resulting in system failure or miscalculations. This problem is generally referred to as the "Year 2000 issue." - 13 - We are in the process of assessing the impact of the Year 2000 issue on our information systems. We have identified potential deficiencies and are addressing them through updates and remediation. In accordance with accounting rules, costs associated with modifying existing computer software for Year 2000 issues will be expensed as incurred. We are also in the process of assessing the measures being taken by our customers and suppliers to address the Year 2000 issues. We are not dependent on any one customer or supplier and our management believes that alternate sources of supply for product components are widely available. We do not expect the cost of implementing the upgrades and remediations to be material. USE OF PROCEEDS The Selling Stockholders are selling all of the Shares covered by this Prospectus for theirits own account. Accordingly, we will not receive any proceeds from the resale of the Shares.shares.

Our certificate of incorporation authorizes us to indemnify our officers, directors and other agents to the fullest extent permitted under Delaware law. Our certificate of incorporation provides that a director is not personally liable for monetary damages to us or our stockholders for breach of his or her fiduciary duties as a director. However, a director will be held liable for a breach of his or her duty of loyalty to us or our stockholders, his or her intentional misconduct or willful violation of law, actions or inactions not in good faith, an unlawful stock purchase or payment of a dividend under Delaware law, or transactions from which the director derives an improper personal benefit. This limitation of liability does not affect the availability of equitable remedies against the director, including injunctive relief or rescission. We have purchased a directors and officers liability and reimbursement policy that covers liabilities of our directors and officers arising out of claims based upon acts or omissions in their capacities as directors and officers. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to our directors, officers or controlling persons pursuant to the foregoing provisions, or otherwise, we have been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

Article VII of the registrant's By-laws provides for indemnification of our directors, officers, employees and agents of the Company to the fullest extent permitted under Delaware law. In addition, Article TENTH of the registrant's Restated Certificate of Incorporation provides, in general, that no director of the registrant shall be personally liable to the registrant or any of its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL (which provides that under certain circumstances, directors may be jointly and severally liable for willful or negligent violations of the DGCL provisions regarding the payment of dividends or stock repurchases or redemptions), as the same exists or hereafter may be amended, or (iv) for any transaction from which the director derived an improper personal benefit.
