In addition to the other information contained in this Prospectus, the following risk factors should be considered carefully in evaluating our business before purchasing the Shares. THERE IS NO ASSURANCE THAT WE WILL SUCCESSFULLY DEVELOP A COMMERCIALLY VIABLE PRODUCT. We are at an early stage of clinical development activities required for drug approval and commercialization. Since our formation in October 1984, we have engaged in developing research programs, recruiting scientific advisors and scientists, negotiating and consummating technology licensing agreements and sponsoring research and development activities. We have generated no revenue from product sales and do not have any products currently available for sale, and none are expected to be commercially available for sale until after March 31, 2003, if at all. There can be no assurance that the research we fund and manage will lead to the development of commercially viable products. WE HAVE A HISTORY OF LOSSES AND AN ACCUMULATED DEFICIT; OUR FUTURE PROFITABILITY IS UNCERTAIN. We have experienced significant operating losses since our inception and we expect to incur additional operating losses as we continue research and development and clinical trial efforts. As of September 30, 2002, we had an accumulated deficit of approximately $40,301,000. We have incurred additional operating losses since such date and expect to incur additional operating losses for the foreseeable future. WE NEED SUBSTANTIAL ADDITIONAL FUNDS. Our operations to date have consumed substantial amounts of cash. Negative cash flow from operations is expected to continue in the foreseeable future. Our cash requirements may vary materially from those now planned because of results of research and development, results of pre-clinical and clinical testing, responses to our grant requests, relationships with strategic partners, changes in the focus and direction of our research and development programs, competitive and technological advances, the Food and Drug Administration ("FDA") regulatory process and other factors. In any of these circumstances, we may require substantially more funds than we currently have available or currently intend to raise to continue our business. We may seek to satisfy future funding requirements through public or private offerings of securities, by collaborative or other arrangements with pharmaceutical companies or from other sources. Additional financing may not be available when needed or may not be available on acceptable terms. If adequate financing is not available, we may not be able to continue as a going concern or may be required to delay, scale back or eliminate certain research and development programs, relinquish rights to certain technologies or product candidates, forego desired opportunities or license third parties to commercialize our products or technologies that we would otherwise seek to develop internally. To the extent we raise additional capital by issuing equity securities, ownership dilution of existing stockholders will result. S-1 THERE IS SUBSTANTIAL DOUBT ABOUT OUR ABILITY TO CONTINUE AS A "GOING CONCERN." We have a shortage of unrestricted working capital and have had recurring losses from operations and negative cash flows from operations since our inception. These factors, among others discussed in this Prospectus, raise substantial doubt about our ability to continue as a going concern. (See "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations," "Item 8. Financial Statements and Supplemental Data" for an explanatory paragraph relating to substantial doubt about our ability to continue as a going concern and elsewhere in our Form 10-K and our Quarterly Reports on Form 10-Q, incorporated by reference in this Prospectus, for further information on our financial position and results of operations). Our ability to continue to operate will ultimately depend upon raising additional funds, attaining profitability and operating at a profit on a consistent basis, which will not occur for some time or may never occur. OUR DEPENDENCE ON KEY PERSONNEL COULD ADVERSELY AFFECT OUR BUSINESS. Our business depends to a significant degree on the continuing contributions of our key management and scientific and technical personnel, as well as on the continued discoveries of scientists, researchers and technicians at The University of North Carolina at Chapel Hill, Duke University, Auburn University and Georgia State University (collectively, the "Consortium") who have entered into an agreement, dated January 15, 1997, as amended, and a License Agreement, dated as of January 28, 2002 (collectively, the "Consortium Agreements"), by which the members of the Consortium have given us exclusive rights to commercialize certain pharmaceutical product candidates developed in the Consortium-member laboratories related to the dication technology. There can be no assurance that the loss of certain members of management or the scientists, researchers and technicians from the Consortium-member universities would not materially adversely affect our business. We do not have "key-man" life insurance policies on any of our executives. ADDITIONAL RESEARCH GRANTS MAY NOT BE AVAILABLE. We will continue to apply for new grants to support continuing research and development of the dication platform technology product candidates. The process of obtaining grants is extremely competitive and there can be no assurance that any of our grant applications will be acted upon favorably. OUR PRODUCT CANDIDATES ARE IN EARLY STAGE CLINICAL TRIALS. All of our product candidates, including DB289 and DB075, require additional clinical testing, regulatory approval and development of marketing and distribution channels, all of which are expected to require substantial additional investment prior to commercialization. There can be no assurance that any of our product candidates will be successfully developed, prove to be safe and effective in human clinical trials, meet applicable regulatory standards, be capable of being produced in commercial quantities at acceptable costs, be eligible for third party reimbursement from governmental or private insurers, be successfully marketed or achieve market acceptance. S-2 THERE ARE SUBSTANTIAL UNCERTAINTIES RELATED TO CLINICAL TRIALS. To obtain required regulatory approvals for the commercial sale of our product candidates, we must demonstrate through clinical trials that such product candidates are safe and effective for their intended uses. We may find, at any stage of our research and development, that product candidates which appeared promising in earlier clinical trials do not demonstrate safety or effectiveness in later clinical trials and therefore do not receive regulatory approvals. The results from pre-clinical testing and early clinical trials may not be predictive of results obtained in later clinical trials and large-scale testing. Companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in various stages of clinical trials, even after promising results had been obtained in earlier stage trials. Completion of the clinical trials may be delayed by many factors, including slower than anticipated patient enrollment, difficulty in securing sufficient supplies of clinical trial materials or adverse events occurring during clinical trials. Completion of testing, studies and trials may take several years, and the length of time varies substantially with the type, complexity, novelty and intended use of the product. Delays or rejections may be based upon many factors, including changes in regulatory policy during the period of product development. No assurance can be given that any of our development programs will be successfully completed, that any Investigational New Drug Application filed with the FDA (or any foreign equivalent filed with the appropriate foreign authorities) will become effective, that additional clinical trials will be allowed by the FDA or other regulatory authorities or that clinical trials will commence as planned. There have been delays in our testing and development schedules to date and there can be no assurance that our future testing and development schedules will be met. WE HAVE NO MANUFACTURING CAPABILITY, WHICH COULD IMPAIR OUR ABILITY TO DEVELOP COMMERCIALLY VIABLE PRODUCTS AT REASONABLE COSTS. Our ability to conduct clinical trials and to commercialize product candidates will depend in part upon our ability to manufacture the product candidates, either directly or through third parties, at a competitive cost and in accordance with FDA and other regulatory requirements. We currently lack facilities and personnel to manufacture our product candidates. There can be no assurance that we will be able to acquire such resources, either directly or through third parties, at reasonable costs if we develop commercially viable products. WE ARE DEPENDENT ON THIRD-PARTY RELATIONSHIPS FOR CRITICAL ASPECTS OF OUR BUSINESS. We follow a business strategy of utilizing the expertise and resources of third parties in a number of areas, including the research and development of potential products, the manufacture of potential products for clinical trial purposes, the conduct of pre-clinical and clinical trials and the future development and manufacture of commercialized drugs. This strategy creates risks by placing critical aspects of our business in the hands of third parties that we may not be able to control. If these third parties do not perform in a timely and satisfactory manner, we may incur costs and delays as we seek alternate sources of such products and services, if available. Such costs and delays may have a material adverse effect on our business. S-3 We may seek additional third-party relationships in certain areas, particularly in clinical testing, marketing, manufacturing and other areas where pharmaceutical company collaborators will enable us to develop particular products or geographic markets which are otherwise beyond our resources and/or capabilities. There is no assurance that we will be able to obtain any such collaboration or any other research and development, manufacturing or clinical trial agreement. Our inability to obtain and maintain satisfactory relationships with third parties may have a material adverse effect on our business. WE ARE UNCERTAIN ABOUT THE ABILITY TO PROTECT OR OBTAIN NECESSARY PATENTS AND PROTECT OUR PROPRIETARY INFORMATION. There can be no assurance that any particular patent will be granted or that issued patents will provide us, directly or through licenses, with the intellectual property protection contemplated. Patents and licenses of patents can be challenged, invalidated or circumvented. It is also possible that competitors will develop similar products simultaneously. Our breach of any license agreement or the failure to obtain a license to any technology or process which may be required to develop or commercialize one or more of our product candidates may have a material adverse effect on our business. The pharmaceutical and biotechnology fields are characterized by a large number of patent filings, and a substantial number of patents have already been issued to other pharmaceutical and biotechnology companies. Third parties may have filed applications for or have been issued patents and may obtain additional patents and proprietary rights related to products or processes competitive with or similar to those that we are attempting to develop and commercialize. We may not be aware of all of the patents potentially adverse to our interests that may have been issued to others. No assurance can be given that patents do not exist, have not been filed or could not be filed or issued, which contain claims relating to or competitive with our technology, products or processes. If patents have been or are issued to others containing preclusive or conflicting claims, then we may be required to obtain licenses to one or more of such patents or to develop or obtain alternate technology. There can be no assurance that the licenses that might be required for such technology, processes or products would be available on commercially acceptable terms, or at all. Because of the substantial length of time and expense associated with bringing new products to the marketplace through the development and regulatory approval process, the biotechnology industry places considerable importance on patent and trade secret protection for new technologies, products and processes. Since patent applications in the United States are confidential until patents are issued and since publication of discoveries in the scientific or patent literature often lag behind actual discoveries, we cannot be certain that we (or our licensors) were the first to make the inventions covered by pending patent applications or that we (or our licensors) were the first to file patent applications for such inventions. The patent positions of pharmaceutical and biotechnology companies can be highly uncertain and involve complex legal and factual questions, and therefore, the breadth of claims allowed in pharmaceutical and biotechnology patents, or their enforceability, cannot be predicted. There can be no assurance that any patents under pending patent applications or any further patent applications will be issued. Furthermore, there can be no assurance that the scope of any patent protection will exclude competitors or provide us competitive advantages, that any of our (or our licensors') S-4 patents that have been issued or may be issued will be held valid if subsequently challenged, or that others, including competitors or current or former employers of our employees, advisors and consultants, will not claim rights in, or ownership to, our (or our licensors') patents and other proprietary rights. There can be no assurance that others will not independently develop substantially equivalent proprietary information or otherwise obtain access to our proprietary information, or that others may not be issued patents that may require us to obtain a license for, and pay significant fees or royalties for, such proprietary information. The pharmaceutical and biotechnology industries have experienced extensive litigation regarding patent and other intellectual property rights. We could incur substantial costs in defending suits that may be brought against us (or our licensors) claiming infringement of the rights of others or in asserting our (or our licensors') patent rights in a suit against another party. We may also be required to participate in interference proceedings declared by the United States Patent and Trademark Office for the purpose of determining the priority of inventions in connection with our (or our licensors') patent applications. Adverse determinations in litigation or interference proceedings could require us to seek licenses (which may not be available on commercially reasonable terms) or subject us to significant liabilities to third parties, and could therefore have a material adverse effect on our business. Even if we prevail in an interference proceeding or a lawsuit, substantial resources, including the time and attention of our officers, will be required. We also rely on trade secrets, know-how and technological advancement to maintain our competitive position. Although we use confidentiality agreements and employee proprietary information and invention assignment agreements to protect our trade secrets and other unpatented know-how, these agreements may be breached by the other party to the agreement or may otherwise be of limited effectiveness or enforceability. CONFIDENTIALITY AGREEMENTS MAY NOT ADEQUATELY PROTECT OUR INTELLECTUAL PROPERTY. We require our employees and consultants to execute confidentiality agreements upon the commencement of their relationship with us. The agreements generally provide that trade secrets and all inventions conceived by the individual and all confidential information developed or made known to the individual during the term of the relationship will be Immtech's exclusive property and must be kept confidential and not disclosed to third parties except in specified circumstances. There can be no assurance, however, that these agreements will provide meaningful protection for our proprietary information in the event of unauthorized use or disclosure of such information. OUR BUSINESS HAS SIGNIFICANT COMPETITION; OUR PRODUCT CANDIDATES MAY BECOME OBSOLETE PRIOR TO COMMERCIALIZATION DUE TO ALTERNATIVE TECHNOLOGIES. The pharmaceutical field is characterized by extensive research efforts and rapid technological progress. Competition from biotechnology companies, pharmaceutical companies and research and academic institutions is intense and other companies are engaged in research and product development for treatment of the same diseases as we are. New developments in molecular cell biology, molecular pharmacology, recombinant DNA technology and other pharmaceutical processes are expected to continue at a rapid pace in both industry and academia. S-5 There can be no assurance that research and discoveries by others will not render some or all of our programs or products noncompetitive or obsolete. We are aware of other companies and institutions dedicated to the development of therapeutics similar to those we are developing, including Eli Lilly and Company, Hoffman-LaRoche Ltd., Chiron Corporation, Cubist Pharmaceuticals, Inc., Schering-Plough Corporation and Abbott Laboratories. Many of our existing or potential competitors have substantially greater financial and technical resources than we do and therefore may be in a better position to develop, manufacture, and market pharmaceutical and biological products. Many of these competitors are also more experienced with regard to pre-clinical testing, human clinical trials and obtaining regulatory approvals. The current or future existence of competitive products may also adversely affect the marketability of our product candidates. THERE IS NO ASSURANCE THAT WE WILL RECEIVE FDA APPROVAL FOR ANY OF OUR PRODUCT CANDIDATES; GOVERNMENT REGULATION MAY IMPEDE, DELAY OR PREVENT THE COMMERCIALIZATION OF OUR PRODUCT CANDIDATES. All new drugs and biologics (a biologic is a naturally occurring protein, or a synthetic form of such protein), including our product candidates, are subject to extensive and rigorous regulation by the federal government, principally the FDA under the Federal Food, Drug and Cosmetic Act and other laws including, in the case of biologics, the Public Health Services Act, and by state, local and foreign governments. Such regulations govern, among other things, the development, testing, manufacture, labeling, storage, pre-market clearance or approval, advertising, promotion, sale and distribution of drugs and biologics. If drug products are marketed abroad, they are subject to extensive regulation by foreign governments. Failure to comply with applicable regulatory requirements may subject us to administrative or judicially imposed sanctions such as civil penalties, criminal prosecution, injunctions, product seizure or detention, product recalls, total or partial suspension of production and FDA refusal to approve pending applications. WE HAVE NOT RECEIVED REGULATORY APPROVAL IN THE UNITED STATES OR ANY FOREIGN JURISDICTION FOR THE COMMERCIAL SALE OF ANY OF OUR PRODUCT CANDIDATES. The process of obtaining FDA and other required regulatory approvals, including foreign approvals, often takes many years and varies substantially based upon the type, complexity and novelty of the products involved and the indications being studied. Furthermore, the approval process is extremely expensive and uncertain. There can be no assurance that our product candidates will be cleared for commercial sale in the United States by the FDA or in foreign countries by foreign regulatory agencies. The regulatory review process can take many years and we will need to raise additional funds prior to completing the regulatory review process for our current and future product candidates. Failure to receive FDA approval for our product candidates would preclude us from marketing and selling such products in the United States. Therefore, the failure to receive FDA approval would have a material adverse effect on our business. Even if regulatory approval of a product is granted, there can be no assurance that we will be able to obtain the labeling claims (a labeling claim is a product's description and its FDA-permitted uses) necessary or desirable for the promotion of such product. FDA regulations prohibit the marketing or promotion of a drug for unapproved indications. Furthermore, regulatory marketing approval may entail ongoing requirements for post-marketing studies if S-6 regulatory approval is obtained; we will then be subject to ongoing FDA obligations and continued regulatory review. In particular, we, or our third party manufacturers, will be required to adhere to regulations setting forth Good Manufacturing Practices which require us (or our third party manufacturers) to manufacture products and maintain records in a prescribed manner with respect to manufacturing, testing and quality control activities. Further, we (or our third party manufacturers) must pass a manufacturing facilities pre-approval inspection by the FDA before obtaining marketing approval. Failure to comply with applicable regulatory requirements may result in penalties such as restrictions on a product's marketing or withdrawal of the product from the market. In addition, identification of certain side effects after a drug is on the market or the occurrence of manufacturing problems could cause subsequent withdrawal of approval, reformulation of the drug, additional pre-clinical testing or clinical trials and changes in labeling of the product. Prior to the submission of an application for FDA approval, our pharmaceutical and biologic product candidates must undergo rigorous pre-clinical and clinical testing, which may take several years and the expenditure of substantial financial and other resources. Before commencing clinical trials in humans, we must submit to the FDA, and receive clearance of, an Investigational New Drug Application ("IND"). There can be no assurance that submission of an IND for future clinical testing of any of our pharmaceutical or biological product candidates under development or other future product candidates would result in FDA permission to commence clinical trials or that we will be able to obtain the necessary approvals for future clinical testing in any foreign jurisdiction. There can be no assurance that if testing of pharmaceutical product candidates under development is completed, any such drug compounds will be accepted for formal review by the FDA or any foreign regulatory body or approved by the FDA for marketing in the United States or by any such foreign regulatory bodies for marketing in foreign jurisdictions. If the product candidate is regulated as a biologic, the FDA will require the submission and approval of both a Product License Application ("PLA") and an Establishment License Application before commercial marketing can commence. The PLA must include detailed information about the biologic and its manufacture and the results of product development, pre-clinical studies and clinical trials. The FDA's time to review PLAs averages two to five years. The FDA may ultimately decide that the PLA does not satisfy its regulatory criteria for approval and deny approval or require additional clinical studies. Future federal, state, local or foreign legislation or administrative acts could also prevent or delay regulatory approval of our pharmaceutical and biologic candidates. THERE IS UNCERTAINTY REGARDING THE AVAILABILITY OF HEALTH CARE REIMBURSEMENT FOR PURCHASERS OF OUR ANTICIPATED PRODUCTS; HEALTH CARE REFORM MAY NEGATIVELY IMPACT THE ABILITY OF PROSPECTIVE PURCHASERS OF OUR ANTICIPATED PRODUCTS TO PAY FOR SUCH PRODUCTS. Our ability to commercialize any of our product candidates will depend in part on the extent to which reimbursement for the costs of the resulting drug or biologic will be available from government health administration authorities, private health insurers and others. Significant uncertainty exists as to the reimbursement status of newly-approved health care products. There can be no assurance of the availability of third-party insurance reimbursement coverage to enable us to establish and maintain price levels sufficient for realization of a profit S-7 on our investment in developing pharmaceutical and biological products. Government and other third-party payers are increasingly attempting to contain health care costs by limiting both coverage and the level of reimbursement for new drug or biologic products approved for marketing by the FDA and by refusing, in some cases, to provide any coverage for uses of approved products for disease indications for which the FDA has not granted marketing approval. If adequate coverage and reimbursement levels are not provided by government and third-party payers for uses of our anticipated products, the market acceptance of these products would be adversely affected. Healthcare reform proposals have previously been introduced in Congress and in various state legislatures and there is no guarantee that such proposals will not be introduced in the future. We cannot predict when any proposed reforms will be implemented, if ever, or the effect of any implemented reforms on our business. There can be no assurance that any implemented reforms will not have a material adverse effect on our business. Such reforms, if enacted, may affect the availability of third-party reimbursement for our anticipated products as well as the price levels at which we are able to sell such products. In addition, if we are able to commercialize products in overseas markets, then our ability to achieve success in such markets may depend, in part, on the health care financing and reimbursement policies of such countries. POTENTIAL ADVERSE EFFECT OF SHARES ELIGIBLE FOR FUTURE SALE. Sales of our Common Stock (including the issuance of shares upon conversion of preferred stock, the exercise of outstanding options and warrants at prices substantially below the current closing market price and the sale of shares upon expiration of restrictions on resale) in the public market could materially and adversely affect the market price of shares of our Common Stock. Such sales also might make it more difficult for us to sell equity securities or equity-related securities in the future at a time and price that we deem appropriate. As of November 27, 2002, we had 6,349,669 shares of Common Stock outstanding (not including 852,940 shares of Common Stock reserved for conversion of Series A Convertible Preferred Stock, 497,531 Shares of Common Stock reserved for conversion of Series B Convertible Preferred Stock, 505,474 shares of Common Stock reserved for exercise of outstanding options and 2,657,062 shares of Common Stock reserved for exercise of outstanding warrants held by certain investors). Of the shares of Common Stock outstanding, 4,338,631 shares of Common Stock are freely tradable without restriction. All of the remaining 2,011,038 shares are restricted from resale except pursuant to certain exceptions under the Securities Act of 1933, as amended (the "Securities Act"). POTENTIAL ADVERSE EFFECT OF OUTSTANDING COMMON STOCK OPTIONS AND WARRANTS. We have outstanding options and warrants for the purchase of shares of our Common Stock which may adversely affect our ability to consummate future equity financings. Further, the holders of such warrants and options may exercise them at a time when we would otherwise be able to obtain additional equity capital on more favorable terms. To the extent any such options and warrants are exercised, the outstanding shares of our Common Stock may be diluted. S-8 THE LISTING OF OUR COMMON STOCK HAS BEEN TRANSFERRED FROM THE NASDAQ NATIONAL MARKET SYSTEM TO THE NASDAQ SMALLCAP MARKET. On March 6, 2002, we received notice from a NASDAQ listing review panel that our stock would be transferred from the NASDAQ National Market System to the NASDAQ SmallCap Market effective March 8, 2002. On March 8, 2002, our Common Stock began trading on the NASDAQ SmallCap Market. Our ability to remain listed on the NASDAQ SmallCap Market is contingent upon compliance with all NASDAQ SmallCap Market requirements, including but not limited to (i) $35 million market capitalization or (ii) stockholders' equity of $2.5 million. NASDAQ HAS GRANTED THE COMPANY AN EXCEPTION TO REMAIN LISTED ON THE SMALLCAP MARKET. Pursuant to an exception granted by NASDAQ on October 10, 2002, we may remain listed on the SmallCap Market. However, under the exception, we must maintain shareholders' equity above SmallCap Market maintenance standards. To comply with the terms of the exception, we must show shareholders' equity of at least $3.5 million (on a proforma basis as of September 30, 2002) in our second quarter Quarterly Report on Form 10-Q filed with the SEC on November 14, 2002, shareholders' equity of at least $5.4 million on or before December 31, 2002 and shareholders' equity of at least $5.1 million for the fiscal quarter ending December 31, 2002. We will be subject to additional NASDAQ listing panel review if we are unable to timely make any of the required disclosures. If we comply with the above disclosures, we will remain subject to traditional NASDAQ SmallCap Market maintenance standards. WE DID NOT MEET THE TERMS OF NASDAQ'S EXCEPTION ON NOVEMBER 14, 2002. On November 14, 2002 we filed with the SEC a Quarterly Report on Form 10-Q reporting shareholders' equity of approximately $1.65 million without pro forma adjustments. We have requested from NASDAQ additional time to raise funds through equity sales to meet the elevated equity requirements of the exception. NASDAQ had not responded to our request as of the date of this Prospectus. IF WE CANNOT SATISFY THE MAINTENANCE REQUIREMENTS OF THE NASDAQ SMALLCAP MARKET, NASDAQ MAY TRANSFER OUR COMMON STOCK TO THE ELECTRONIC BULLETIN BOARD. If we fail to meet the listing maintenance requirements of the NASDAQ SmallCap Market and NASDAQ rules, which require, among other things, minimum shareholders' equity of $2.5 million or $35 million market capitalization and a minimum bid price for our Common Stock of $1.00, we may be subject to transfer from the NASDAQ SmallCap Market. Trading, if any, of our Common Stock would thereafter be conducted in the over-the-counter market in the so-called "pink sheets" or on the National Association of Securities Dealers, Inc. ("NASD") "electronic bulletin board" (the "OTC Bulletin Board"). As a consequence of any such transfer, a stockholder would likely find it more difficult to dispose of, or to obtain accurate quotations as to the prices of, our Common Stock. Effective January 1, 2003, the OTC Bulletin Board will no longer offer companies a market on which to trade. The NASD's new Bulletin Board Exchange ("BBX Exchange"), which is intended to replace the OTC Bulletin Board, may have stricter listing standards. If we fail to meet the BBX Exchange listing requirements, then we would be forced to trade on the pink sheets, a market with very limited liquidity and minimal listing standards. S-9 IF OUR COMMON STOCK IS TRANSFERRED TO THE PINK SHEETS OR THE OTC BULLETIN BOARD (OR THE BBX EXCHANGE), IT MAY BECOME SUBJECT TO THE SEC'S "PENNY STOCK" RULES, WHICH MAY MAKE SHARES OF OUR COMMON STOCK MORE DIFFICULT TO SELL. SEC rules require brokers to provide certain information to purchasers of securities traded at less than $5.00 and not traded on a national securities exchange or quoted on the NASDAQ Stock Market (a "penny stock"). If our Common Stock becomes a penny stock that is not exempt from these SEC rules, these disclosure requirements may have the effect of reducing trading activity in our Common Stock and making it more difficult for investors to sell. The rules require a broker to deliver a risk disclosure document that provides information about penny stocks and the nature and level of risks in the penny stock market. The broker must also give bid and offer quotations and broker and salesperson compensation information to the customer orally or in writing before or with the confirmation. The SEC rules also require a broker to make a special written determination that the penny stock is a suitable investment for the purchaser and receive the purchaser's written agreement to the transaction before completion of the transaction. THE MARKET PRICE OF OUR COMMON STOCK MAY EXPERIENCE SIGNIFICANT VOLATILITY. The securities markets from time to time experience significant price and volume fluctuations unrelated to the operating performance of particular companies. In addition, the market prices of the common stock of many publicly traded pharmaceutical and biotechnology companies have been and can be expected to be especially volatile. Announcements of technological innovations or new products by us or our competitors, developments or disputes concerning patents or proprietary rights, publicity regarding actual or potential clinical trial results relating to products under development by us or our competitors, regulatory developments in both the United States and foreign countries, delays in our testing and development schedules, public concern as to the safety of vaccines or biological products and economic and other external factors, as well as period-to-period fluctuations in our financial results, may have a significant impact on the market price of our Common Stock. The realization of any of the risks described in these "Risk Factors" may have a significant adverse impact on such market price. WE DO NOT PAY DIVIDENDS ON OUR COMMON STOCK. We have never declared or paid dividends on our Common Stock and we do not intend to pay any Common Stock dividends in the foreseeable future. Our Series A Convertible Preferred Stock ("Series A Stock") earns a 6% per annum dividend and our Series B Convertible Preferred Stock ("Series B Stock") earns an 8% per annum dividend, in both cases payable semi-annually on each April 15th and October 15th while any shares of Series A Stock or Series B Stock, as the case may be, are outstanding. These dividends, at our option, may be paid in cash or in shares of Common Stock. THERE ARE LIMITATIONS ON THE LIABILITY OF OUR DIRECTORS, AND WE MAY HAVE TO INDEMNIFY OUR OFFICERS AND DIRECTORS IN CERTAIN INSTANCES. Our Certificate of Incorporation limits, to the maximum extent permitted by Delaware law, the personal liability of our directors for monetary damages for breach of their fiduciary S-10 duties as directors. Our Bylaws provide that we shall indemnify our officers and directors and may indemnify our employees and other agents to the fullest extent permitted by law. We have entered into indemnification agreements with our officers and directors containing provisions which are in some respects broader than the specific indemnification provisions contained in Delaware law. The indemnification agreements may require us, among other things, to indemnify such officers and directors against certain liabilities that may arise by reason of their status or service as directors or officers (other than liabilities arising from willful misconduct of a culpable nature), to advance their expenses incurred as a result of any proceeding against them as to which they could be indemnified, and to obtain directors' and officers' insurance if available on reasonable terms. Section 145 of the Delaware General Corporation Law provides that a corporation may indemnify a director, officer, employee or agent made or threatened to be made a party to an action by reason of the fact that he was a director, officer, employee or agent of the corporation or was serving at the request of the corporation, against expenses actually and reasonably incurred in connection with such action if he or she acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. Delaware law does not permit a corporation to eliminate a director's duty of care, and the provisions of our Certificate of Incorporation have no effect on the availability of equitable remedies, such as injunction or rescission, for a director's breach of the duty of care. ABOUT THIS PROSPECTUS This document is called a Prospectus and is part of a registration statement on Form S-3 (the "Registration Statement") that we filed with the SEC using a "shelf" registration or continuous offering process. Under this shelf Prospectus, the Selling Stockholders may from time to time collectively offer up to 1,221,344 Shares of our Common Stock. This Prospectus provides you with a general description of the securities the Selling Stockholders may offer. We may file a prospectus supplement with the SEC via its Electronic Data Gathering, Analysis, and Retrieval ("EDGAR") which may include a discussion of any risk factors or other special considerations applicable to those securities.

S-13 THE COMPANY AN INVESTMENT IN THE SECURITIES OFFERED BY THIS PROSPECTUS INVOLVES A HIGH DEGREE OF RISK. PROSPECTIVE INVESTORS SHOULD CONSIDER CAREFULLY THE INFORMATION PROVIDED UNDER "RISK FACTORS" BEGINNING ON PAGE S-1. A GLOSSARY WHICH DEFINES VARIOUS TERMS USED IN THIS PROSPECTUS BEGINS ON PAGE S-24. We are a pharmaceutical company focused on the development and commercialization of drugs to treat infectious diseases that include fungal infections, malaria, tuberculosis, hepatitis C, pneumonia, diarrhea and African sleeping sickness, and cancer. We hold worldwide patents, licenses and rights to license worldwide patents, patent applications and technologies from third parties that are integral to our business. Since our formation in October 1984, we have engaged in research and development programs, expanding our network of scientists and scientific advisors, negotiating and consummating technology licensing agreements and advancing technology platform toward commercialization. We use the expertise and resources of strategic partners and contracted parties in a number of areas, including: (i) laboratory research, (ii) pre-clinical and human clinical trials and (iii) the manufacture of pharmaceutical products. We have licensing and exclusive commercialization rights to a dicationic anti-infective pharmaceutical platform and are developing drugs intended for commercial use based on that platform. These dication pharmaceuticals work by blocking life-sustaining enzymes from binding to the key sites in the "minor groove" of an organism's deoxyribonucleic acid ("DNA"), thereby killing the infectious organisms that cause fungal, parasitic, bacterial and viral diseases. The minor groove or key site on an organism's DNA is an area where enzymes interact with the DNA as part of their normal life cycle. We do not have any commercially available products nor do we expect to have any commercially available products for sale until after March 31, 2003, if at all. Our pharmaceutical program is based on technology for developing a class of compounds known as dications. The dication technology is the result of a research program designed to understand how dications bind to the DNA of infectious microorganisms. The dication platform was developed by scientists at The University of North Carolina at Chapel Hill ("UNC"), Duke University ("Duke"), Auburn University ("Auburn") and Georgia State University ("Georgia State") (collectively, the "Consortium"). We entered into an agreement with the Consortium, dated January 15, 1997, as amended, and a License Agreement, dated as of January 28, 2002 (collectively, the "Consortium Agreements"), to commercialize product candidates resulting from the Consortium's research, including the dication technology. Structurally, dications are chemical molecules which have two positively charged ends that are held together by a chemical linker. The composition of the dications, with positive charges on both ends (shaped like molecular barbells), allows dications to bind (similar to a bandaid) to the negatively charged active sites (sites where enzymes interact with DNA) in certain areas of an infectious microorganism's DNA. The bound dications prevent enzymes necessary to the life of the microorganism from attaching to certain of its DNA's active sites. Research has shown that once a site is occupied by a dication, enzymes necessary to the life of the infectious microorganism are blocked and the infectious microorganism dies. S-14 STRATEGY Our strategy is to develop drugs effective against infectious diseases and cancer by utilizing the dicationic platform technology developed by Consortium scientists. Our plan is to commercialize dications first in certain niche markets by taking advantage of fast-track FDA approvals permitted in those areas due to the absence of currently available effective treatment in such markets. We believe that our first products will demonstrate the power and versatility of the dication platform technology. We then intend to work on developing treatments for other infectious diseases which afflict large populations of people. We intend to continue to cooperate with and oversee the results of independent researchers and to use business-sponsored research programs, joint ventures and other forms of collaborative programs for product development, manufacturing and, subject to regulatory review of a product candidate, marketing. We consider our current collaborative relationships significant to the successful development of our business and we believe that we will enter into additional arrangements in the future to develop, manufacture and market not only the product candidates on which we are currently focusing, but also those dications which the Consortium members are developing (and are expected to develop in the future) for future commercialization. PRODUCT CANDIDATES The information below is a summary of our product candidates. Pharmaceutical Products - Dications The platform technology, the result of the Consortium's research programs, is focused on understanding how dications bind to the DNA of infectious microorganisms. Through the Consortium Agreements, we have been granted certain exclusive rights to the platform technology (and the dications created with such technology) and to develop and commercialize dications. The methodology used by the Consortium researchers to develop dications evolved into the Consortium's platform technology for designing dications to treat infectious diseases. The Consortium is using this platform technology to design new treatments for a range of infectious diseases, including protozoan, fungal, bacterial and viral infections. In May 2001, we completed single- and multi-dose safety trials of the dication DB289 in human volunteers. In these trials, DB289 was shown to be safe to humans at dosage levels expected to be effective against disease. DB289 is designed to be delivered orally to patients without toxic side effects. Since DB289 can be given orally, we anticipate that it will be self-administered, thus making it practical to deliver and substantially less expensive than competitive products. On March 27, 2002, we were granted FDA approval to export DB289 to the Democratic Republic of the Congo to open a second Phase II clinical site which allowed us to increase the enrollment of patients in our clinical trial for African sleeping sickness and expedite DB289's Phase II testing process. In September 2002, we completed a Phase IIa human clinical trial of DB289 for the treatment of Trypanosomiasis (African sleeping sickness). Initial trial results showed that DB289 was well tolerated and approximately 95% of the patients treated were cured. Trial S-15 participants were requested to attend a follow-up exam three months after the conclusion of their treatment; all of the patients who returned continued to be parasite-free. Trypanosomiasis is a parasitic disease transmitted by the tsetse fly. Individuals infected with the disease suffer from symptoms starting with fever, itchy skin, joint pain and lethargy. Weeks after contracting the disease, when the parasite migrates through the circulatory system to the brain, Trypanosomiasis may cause trembling, hallucinations and erratic behavior. Trypanosomiasis can result in coma and death if left untreated. Sixty million people in sub-Sahara Africa are exposed to Trypanosomiasis and approximately 500,000 new cases are reported each year. DB289 is a dicationic pharmaceutical compound designed to be the first oral drug to treat, as well as to prevent, this potentially fatal disease. This Phase IIa study was the first human trial to test the efficacy of our anti-infective, dication pharmaceutical platform and its patented prodrug (oral delivery) technology. The Phase IIa study was conducted at testing facilities in The Democratic Republic of the Congo and Angola. Later this year, we plan to commence a Phase IIb clinical trial to test the efficacy of DB289 for treatment of Trypanosomiasis in a larger patient population. The clinical trial program is part of a clinical research subcontract between us and UNC ("Clinical Research Agreement") funded by $9.8 million of a $15.1 million grant to UNC from the Bill & Melinda Gates Foundation ("Gates Foundation"). DB289 has demonstrated improved safety and effectiveness when compared to existing treatments in animal models. We have initiated a second Phase IIa study of DB289 in South Africa and Peru for the treatment of Pneumocystis carinii pneumonia ("PCP") with HIV and AIDS patients. PCP, a disease which affects immuno-suppressed patients, can be fatal if not treated. The primary use of the drug would be for long-term prophylaxis of patients at risk for PCP. This Phase IIa human trial will be managed by Quintiles Transnational Corporation, a company that provides global clinical trial services for all phases of human drug development. Additionally, we are planning a Phase II clinical trial that will target malaria. Our goal is to commence this study at an established clinical site in Thailand by the end of 2002. The dication compound selected for the malaria study has displayed excellent activity in vitro against both common and drug-resistant forms of the disease. The proposed dosage for this trial is similar to dosages demonstrated to be safe in the recently completed African sleeping sickness studies. According to an article published in 2002 by "Nature" magazine, over two billion people live in areas where malaria is prevalent. Malaria is a parasitic disease spread by mosquitoes that affects about 500 million people per year and is often fatal when contracted by children. The New York Times reported (May 28, 2002) that over 2,000 African children die each day of malaria. The World Health Organization highlighted the dangerous growth of malaria's drug-resistant strains and has ranked malaria at the top of a list of diseases urgently in need of better treatments. We believe DB289 is well suited to demonstrate the power and versatility of the dicationic technology platform and the effectiveness of the dicationic oral drug delivery ("pro-drug") technology. S-16 Other Pharmaceutical Programs Our other pharmaceutical research programs include antifungal, Mycobacterium tuberculosis ("TB"), hepatitis C, Leishmaniasis, H. Pylori and cancer programs. Our antifungal program focuses on developing a new orally delivered dication with effectiveness against the three most common forms of fungi, which are Candida, Asperigillus and Cryptococcus. During the previous 12 months, the Consortium screened a series of new compounds for effectiveness against the three strains of fungi and the Consortium researchers identified several new dicationic compounds that showed promising results. We, in cooperation with scientists from Consortium members Duke, UNC and Georgia State, are progressing on the selection of a new antifungal drug candidate. The estimated annual market for such drug is $4 billion. Together with Immtech, Consortium scientists have identified several exciting new compounds with potential to treat both Candida and Aspergillus, two infections that in the aggregate account for over 90% of the systemic fungal infection drug market. We plan to advance a lead compound into pre-clinical development in 2003. In the TB program, the National Institutes of Health ("NIH") researchers have also been evaluating the Consortium's dications for effectiveness against TB, having screened over 500 of the Consortium's dications. The NIH screening test has identified approximately 10 to 15 dications with activity comparable, or superior, in performance to drugs currently available for the treatment of TB. Additionally, Dr. Scott G. Franzblau of the University of Illinois-Chicago ("UIC"), a recognized expert in TB research, has joined the Consortium to test dications for effectiveness against TB. We will assist Dr. Franzblau to obtain new grants and we have given a grant of approximately $74,000 to UIC to fund Dr. Franzblau's studies. Tests conducted at UIC have identified several compounds that have displayed excellent activity against most common and drug-resistant forms of TB. According to the World Health Organization (the "WHO"), approximately 2 billion people are infected with TB and approximately 10% will develop the disease at some point in their lives. The WHO estimates that there will be 8 million new cases of TB each year and, of these, 2.5 million infected persons will die. TB affects 2 billion people, infects 8 million new cases per year and results in over 2 million annual deaths worldwide. TB has a 25% mortality rate due primarily to unavailability of or inadequate treatment. We anticipate advancing a lead compound into pre-clinical/clinical development in 2003. In the hepatitis program, scientists at Auburn have developed a laboratory screening test using the bovine viral diarrhea virus ("BVDV") as a substitute for the hepatitis C virus ("HCV") to gauge the potential for effectiveness of dications against HCV. The Auburn scientists have advanced the dicationic candidates believed to have the greatest potential for effectiveness into a special animal (mouse) model that develops a chronic viral infection of BVDV. The results of this animal model are expected to help the researchers determine which dications will be further studied or advanced into primate or other advanced animal models of HCV. In the Leishmaniasis program, also part of the Gates Foundation grant, we are working with The London School of Hygiene and Tropical Medicine in England ("The London School"), Ohio State University ("OSU"), UNC and Georgia State to develop a drug to treat Leishmaniasis. The U.S. military supported initial work of the Leishmaniasis program with a S-17 grant of approximately $80,000 to Georgia State to develop dications that were screened in the military's laboratory for potential for effectiveness. The London School and OSU have sub-contracted with the Consortium to screen the drug candidates supplied by Georgia State and UNC. The London School researchers have screened Consortium dications for effectiveness in animal tests and have identified compounds with notable activity. The identified dications have shown potential for effectiveness equivalent to or better than drugs currently used to treat Leishmaniasis. We are responsible (under the Clinical Research Agreement with UNC in connection with the Gates Foundation grant) for the pre-clinical development of a new drug resulting from the Consortium, OSU and The London School research for treatments of Leishmaniasis. In the H. Pylori program, our scientific collaborators performed in vivo tests to identify antibiotics currently on the market that have synergy with DB289 for the treatment of H. pylori. Currently, a combination of antibiotics are used to treat this disease, but over 30% of those treated under current methods have chronic reoccurrence of the disease. H. pylori is a bacteria commonly found in the stomach gastric intestinal track that causes 90% of gastric ulcers worldwide. We are planning to conduct a Phase II pilot study of patients with H. pylori in 2003. In the cancer program, the National Cancer Institute (the "NCI") has tested over 550 of the Consortium's dications for anti-cancer activity, reporting that a significant number of the dications tested have either retarded or killed cancer cells. The NCI has identified 47 of the Consortium's dications as displaying specificity (effectiveness against specific cancer types) and potency as anti-cancer agents. Eighteen have been identified by the NCI to advance to animal (mouse) model testing. Early test results show that specific dications may be effective against different cancer types and that most of the dications tested had some effectiveness even at low doses. While the Consortium's dications have shown effectiveness against cancer, this research is at an early stage and the treatment of cancer is a highly specialized endeavor that is outside the scope of our current expertise. We intend to seek partners to jointly develop and commercialize the dications in our cancer program. We are energized by the successes of our studies and the demand for treatments for our targeted diseases. Our focus is to meet the tremendous need for new drugs by safely and rapidly advancing compounds for each of our targeted diseases through the clinic and into commercialization. Building on those tests and demands, we intend to dedicate efforts and resources in 2003 to the following goals: o the commencement of a Phase IIb clinical trial to treat African sleeping sickness in four to five sub-Sahara African sites, o completion of a Phase IIa study of the efficacy of DB289 against PCP, o commencement of a Phase IIa trial to treat malaria in Thailand with completion expected within the first half of 2003, and o completion of preclinical evaluation on DB289's synergy with other antibiotics in the first quarter of 2003 and to start a human trial for the treatment of H. pylori. The trial is designed to show the effectiveness of combining DB289 with other drugs used to treat gastric ulcers to cure H. pylori, a disease with a high rate of reoccurrence.
