You should read this entire prospectus, including the information incorporated by reference and the financial data and related notes, before making an investment decision. When used in this prospectus, the terms "we," "our" and "us" refer to Hemispherx and not to the selling stockholders. About Hemispherx In the course of almost three decades, we have established a strong foundation of laboratory, pre- clinical and clinical data with respect to the development of nucleic acids to enhance the natural antiviral defense system of the human body and the development of therapeutic products for the treatment of chronic diseases. Our strategy is to obtain the required regulatory approvals which will allow the progressive introduction of Ampligenr (our proprietary drug) for treating Myalgic Encephalomyelitis/ Chronic Fatigue Syndrome ("ME/CFS"), HIV, Hepatitis C ("HCV") and Hepatitis B ("HBV") in the U.S., Canada Europe and Japan. Ampligenr is currently in phase III clinical trials in the U.S. for use in treatment of ME/CFS and is in Phase IIb Clinical Trials in the U.S. for the treatment of newly emerged multi-drug resistant HIV, and for the induction of cell mediated immunity in HIV patients that are under control using potentially toxic drug cocktails. Our proprietary drug technology utilizes specifically configured ribonucleic acid ("RNA") and is protected by more than 350 patents worldwide, with over 80 additional patent applications pending to provide further proprietary protection in various international markets. Certain patents apply to the use of Ampligenr alone and certain patents apply to the use of Ampligenr in combination with certain other drugs. Some compositions of matter patents pertain to other new medications, which have a similar mechanism of action. We were incorporated in Maryland in 1966 under the name HEM Research, Inc., and originally served as a supplier of research support products. Our business was redirected in the early 1980's to the development of nucleic acid pharmaceutical technology and the commercialization of RNA drugs. We were reincorporated in Delaware and changed our name to HEM Pharmaceutical Corp., in 1991 and to Hemispherx Biopharma, Inc., in June 1995. We have three domestic subsidiaries `BioPro Corp., BioAegean Corp., and Core BioTech Corp., all of which are incorporated in Delaware. Our foreign subsidiaries include Hemispherx Biopharma Europe N.V./S.A. established in Belgium in 1998 and Hemispherx Biopharma Europe S.A. incorporated in Luxembourg in 2002. Our 4 principal executive offices are located at One Penn Center, 1617 JFK Boulevard, Philadelphia, Pennsylvania 19103, and its telephone number is 215- 988-0080. Recent Developments On March 20, 2002, our European Subsidiary Hemispherx Biopharma Europe, S.A. ("Hemispherx, S.A.") entered into a Sales and Distribution agreement with Laboratorios Del Dr. Esteve S.A. ("Esteve"). Pursuant to the terms of the agreement, Esteve was granted the exclusive right to market Ampligenr in Spain, Portugal and Andorra for the treatment of Myalgic/Chronic Fatigue Syndrome ("ME/CFS"). In addition to other terms and other projected payments, Esteve paid an initial and non-refundable fee of 625,000 Euros (approximately $545,000) to Hemispherx S.A. on April 24, 2002. Esteve is to pay a fee of 1,000,000 Euros after U.S. Food and Drug Administration approval of Ampligenr for the treatment of ME/CFS and a fee of 1,000,000 Euros upon Spain's approval of the final marketing authorization for using Ampligenr for the treatment of ME/CFS. Also, Esteve purchased 1,000,000 Euros of Hemispherx S.A.'s convertible preferred equity certificates. These securities pay a 7% dividend and were to be converted into 1.14% of the outstanding common stock of Hemispherx S.A. upon the earlier of the completion of an initial public offering ("IPO") on a European stock exchange or September 30, 2003. However, at our request, on January 10,2003, Esteve agreed to convert the preferred equity certificates into our common stock. The conversion rate will be 300 shares of our common stock for each 1,000 Euros convertible preferred certificate. Risk Factors Special Note Regarding Forward-Looking Statements Certain statements in this document constitute "forwarding-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities and Exchange Act of 1995 (collectively, the "Reform Act"). Certain, but not necessarily all, of such forward-looking statements can be identified by the use of forward- looking terminology such as "believes," "expects," "may," "will," "should," or "anticipates" or the negative thereof or other variations thereon or comparable terminology, or by discussions of strategy that involve risks and uncertainties. All statements other than statements of historical fact, included in this prospectus regarding our financial position, business strategy and plans or objectives for future operations are forward-looking statements. Without limiting the broader description of forward-looking statements above, we specifically note that statements regarding potential drugs, their potential therapeutic effect, the possibility of obtaining regulatory approval, our ability 5 to manufacture and sell any products, market acceptance or our ability to earn a profit from sales or licenses of any drugs or our ability to discover new drugs in the future are all forward-looking in nature. Such forward-looking statements involve known and unknown risks, uncertainties and other factors, including but not limited to, the risk factors discussed below, which may cause the actual results, performance or achievements of Hemispherx and its subsidiaries to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements and other factors referenced in this prospectus. We do not undertake and specifically declines any obligation to publicly release the results of any revisions which may be made to any forward-looking statement to reflect events or circumstances after the date of such statements or to reflect the occurrence of anticipated or unanticipated events. The following cautionary statements identify important factors that could cause our actual result to differ materially form those projected in the forward- looking statements made in this Prospectus. Among the key factors that have a direct bearing on our results of operations are: No assurance of successful product development of Ampligen The development of Ampligen and our other products is subject to a number of significant risks. Ampligen may be found to be ineffective or to have adverse side effects, fail to receive necessary regulatory clearances, be difficult to manufacture on a commercial scale, be uneconomical to market or be precluded from commercialization by proprietary right of third parties. Our products are in various stages of clinical and pre-clinical development and, require further clinical studies and appropriate regulatory approval processes before any such products can be marketed. We do not know when, or if ever, Ampligen or our other products will be generally available for commercial sale for any indication. Generally, only a small percentage of potential therapeutic products are eventually approved by the U.S. Food and Drug Administration ("FDA") for commercial sale. Our drug and related technologies are investigational and subject to regulatory approval. All of our drugs and associated technologies are investigational and must receive prior regulatory approval by appropriate regulatory authorities for general use and are currently legally available only through clinical trials with specified disorders. Our principal development efforts are currently focused on Ampligen, which has not been approved for commercial use. Our products, including Ampligen, 6 are subject to extensive regulation by numerous governmental authorities in the U.S. and other countries, including, but not limited to, the FDA in the U.S., the Health Protection Branch("HPB ") of Canada, and the European Medical Evaluation Agency ("EMEA") in Europe. Obtaining regulatory approvals is a rigorous and lengthy process and requires the expenditure of substantial resources. In order to obtain final regulatory approval of a new drug, we must demonstrate to the satisfaction of the regulatory agency that the product is safe and effective for its intended uses and that we are capable of manufacturing the product to the applicable regulatory standards. We require regulatory approval in order to market Ampligen or any other proposed product and receive product revenues or royalties. We cannot assure you that the drug will ultimately be demonstrated to be safe or efficacious. In addition, while Ampligen is authorized for use in clinical trials in the United States and other countries, we cannot assure you that additional clinical trial approvals will be authorized in the United States or in other countries, in a timely fashion or at all, or that we will complete these clinical trials. If Ampligen or one of our other products does not receive regulatory approval in the U.S. or elsewhere, our operations will be materially adversely effected. We may continue to incur substantial losses and our future profitability is uncertain. We began operations in 1966 and last reported net profit from 1985 through 1987. Since 1987, we have incurred substantial operating losses, as we pursued our clinical trial effort and expanded our efforts in Europe. As of September 30, 2002 our accumulated deficit was approximately $97,662,000. We have not yet generated significant revenues from our products and may incur substantial and increased losses in the future. We cannot assure that we will ever achieve significant revenues from product sales or become profitable. We require, and will continue to require, the commitment of substantial resources to develop our products. We cannot assure that our product development efforts will be successfully completed or that required regulatory approvals will be obtained or that any products will be manufactured and marketed successfully, or profitability. We will require additional financing which may not be available. The development of our products will require the commitment of substantial resources to conduct the time-consuming research, preclinical development, and clinical trials that are necessary to bring pharmaceutical products to market. Based on our current operating plan, we anticipate receipt of limited revenues and proceeds from the sales of Ampligen under the Cost Recovery Clinical Programs and holders of non-public warrants exercising their warrants from time to time. We believe these proceeds and the cash on hand will be sufficient to meet our capital requirements through May, 2003. We will need to raise substantial additional 7 funds through additional equity or debt financing or from other sources in order to complete the necessary clinical trials and the regulatory approval processes and begin commercializing its products. In this regard, we have registered 5,000,000 shares for sale pursuant to the registration statement that contains this prospectus. There can be no assurances that we will raise adequate funds from the sale of these shares or that our non-public warrants will be exercised or that we will raise any proceeds from other possible equity financing, which may have a material effect on our ability to develop our products. Moreover, should the value of our common equity securities owned by non- affiliates fall below $75,000,000, we will not be able to sell the above mentioned shares that we have registered. No regulatory agency has approved the full commercial sale of any of our products. We cannot assure you that Ampligen or any of our products being developed will ultimately be demonstrated to be safe or efficacious. While Ampligen is authorized for use in clinical trials in the United States and various other countries, we cannot assure you that additional clinical trial approvals will be authorized in the United States, or in other countries in a timely fashion or at all or that we will complete these clinical trials. If Ampligen or one of our other products does not receive regulatory approval in the United States or elsewhere, our operations will be significantly affected. We may not be profitable unless we can protect our patents and/or receive approval for additional pending patents. We need to preserve and acquire enforceable patents covering the use of Ampligen for a particular disease in order to obtain exclusive rights for the commercial sale of Ampligen for such disease. Our success depends, in large part, on our ability to preserve and obtain patent protection for our products and to obtain and preserve our trade secrets and expertise. We have been issued certain patents including those on the use of Ampligen and Ampligen in combination with certain other drugs for the treatment of HIV. We also have been issued patents on the use of Ampligen in combination with certain other drugs for the treatment of chronic hepatitis B virus, chronic hepatitis C virus, and a patent which affords protection on the use of Ampligen in patients with chronic fatigue syndrome. We have not yet been issued any patents in the United States for the use of Ampligen? as a sole treatment for any of the cancers which we have sought to target. We cannot assure you that any of these applications will be approved or that our competitors will not seek and obtain patents regarding the use of Ampligen in combination with various other agents, for a particular target indication prior to us. If we cannot protect our patents covering the use of Ampligen for a particular 8 disease, or obtain additional pending patents, we may not be able to successfully market Ampligen. The patent position of biotechnology and pharmaceutical firms is highly uncertain and involves complex legal and factual questions. To date, no consistent policy has emerged regarding the breadth of protection afforded by pharmaceutical and biotechnology patents. There can be no assurance that new patent applications relating to our products or technology will result in patents being issued or that, if issued, such patents will afford meaningful protection against competitors with similar technology. It is generally anticipated that there may be significant litigation in the industry regarding patent and intellectual property rights. Such litigation could require substantial resources from us and we may not have the financial resources necessary to enforce the patent rights that we hold. No assurance can be made that our patents will provide competitive advantages for our products or will not be successfully challenged by competitors. No assurance can be given that patents do not exist or could not be filed which would have a materially adverse effect on our ability to market our products or to obtain or maintain any competitive position the we may achieve with respect to our products. Our patents also may not prevent others from developing competitive products using related technology. There can be no assurance that we will be able to obtain necessary licenses if we cannot enforce patent rights we may hold. If we cannot enforce the patent rights we currently hold we may be required to obtain licenses from others to develop, manufacture or market our products. There can be no assurance that we would be able to obtain any such licenses on commercially reasonable terms, if at all. We currently license certain proprietary information from third parties, some of which may have been developed with government grants under circumstances where the government maintained certain rights with respect to the proprietary information developed. No assurances can be given that such third parties will adequately enforce any rights they may have or that the rights, if any, retained by the government will not adversely affect the value of our license. Certain of our know-how and technology is not patentable, particularly the procedures for the manufacture of our drug product which are carried out according to standard operating procedure manuals. 9 We may not be profitable unless we can produce Ampligen or other products in commercial quantities at costs acceptable to us. We have never produced Ampligen or any other products in large commercial quantities. Ampligen is currently produced for use in clinical trials. We must manufacture our products in compliance with regulatory requirements in large commercial quantities and at acceptable costs in order for us to be profitable. We intend to utilize third-party manufacturers and/or facilities if and when the need arises or, if we are unable to do so, to build or acquire commercial-scale manufacturing facilities. If we cannot manufacture commercial quantities of Ampligen or enter into third party agreements for its manufacture at costs acceptable to us, our operations will be significantly affected. If our distributors do not market our product successfully, we may not generate significant revenues or become profitable. We have limited marketing and sales capability. We need to enter into marketing agreements and third party distribution agreements for our products in order to generate significant revenues and become profitable. To the extent that we enter into co-marketing or other licensing arrangements, any revenues received by us will be dependent on the efforts of third parties, and there is no assurance that these efforts will be successful. Our agreement with Gentiva Health Services offers the potential to provide significant marketing and distribution capacity in the United States while licensing and marketing agreements with certain foreign firms should provide an adequate sales force in South America, Africa, United Kingdom, Australia and New Zealand, Canada, Austria, Spain and Portugal. We cannot assure that our domestic or our foreign marketing partners will be able to successfully distribute our products, or that we will be able to establish future marketing or third party distribution agreements on terms acceptable to us, or that the cost of establishing these arrangements will not exceed any product revenues. The failure to continue these arrangements or to achieve other such arrangements on satisfactory terms could have a materially adverse effect on us. Ampligen safety profile and Scientific Literature. We believe that Ampligen has been generally well tolerated with a low incidence of clinical toxicity, particularly given the severely debilitating or life threatening diseases that have been treated. A mild flushing reaction has been observed in approximately 15% of patients treated in our various studies. This reaction is occasionally accompanied by erythema, a tightness of the chest, tachycardia, anxiety, shortness of breath, subjective reports of ''feeling hot,'' sweating 10 and nausea. The reaction is usually infusion-rate related and can generally be controlled by slowing the infusion rate. Other adverse side effects include liver enzyme level elevations, diarrhea, itching, urticaria (swelling of the skin), bronchospasm, hypotension, photophobia, rash, bradycardia, transient visual disturbances, transient arrhythmias, decreased visual activity in platelets and white blood cell counts, anemia, dizziness, confusion, elevation of kidney function tests, occasional temporary hair loss and various flu-like symptoms, including fever, chills, fatigue, muscular aches, joint pains, headaches, nausea and vomiting. These flu-like side effects typically subside within several months. One or more of the potential side effects might deter usage of Ampligen in certain clinical situations and therefore, could adversely effect potential revenues and physician/patient acceptability of our product. There is no assurance that successful manufacture of a drug on a limited scale basis for investigational use will lead to a successful transition to commercial, large- scale production. Small changes in methods of manufacturing may affect the chemical structure of Ampligen and other RNA drugs, as well as their safety and efficacy. Changes in methods of manufacture, including commercial scale-up may affect the chemical structure of Ampligen? and, can, among other things, require new clinical studies and affect orphan drug status, particularly, market exclusivity rights , if any, under the Orphan Drug Act. The transition from limited production of pre-clinical and clinical research quantities to production of commercial quantities of our products will involve distinct management and technical challenges and will require additional management and technical personnel and capital to the extent such manufacturing is not handled by third parties. There can be no assurance that our manufacturing will be successful or that any given product will be determined to be safe and effective, capable of being manufactured economically in commercial quantities or successfully marketed. Rapid technological change may render our products obsolete or non-competitive. The pharmaceutical and biotechnology industries are subject to rapid and substantial technological change. Technological competition from pharmaceutical and biotechnology companies, universities, governmental entities and others diversifying into the field is intense and is expected to increase. Most of these entities have significantly greater research and development capabilities than us, as well as substantial marketing, financial and managerial resources, and represent significant competition for us. There can be no assurance that developments by others will not render our products or technologies obsolete or noncompetitive or that we will be able to keep pace with technological developments. 11 Our products are subject to substantial competition. Competitors have developed or are in the process of developing technologies that are, or in the future may be, the basis for competitive products. Some of these products may have an entirely different approach or means of accomplishing similar therapeutic effects to products being developed by us. These competing products may be more effective and less costly than our products. In addition, conventional drug therapy, surgery and other more familiar treatments will offer competition to our products. Furthermore, many of our competitors have significantly greater experience than us in pre-clinical testing and human clinical trials of pharmaceutical products and in obtaining FDA, HPB and other regulatory approvals of products. Accordingly, our competitors may succeed in obtaining FDA,HPB or other regulatory product approvals more rapidly than us. If any of our products receive regulatory approvals and we commence commercial sales of our products, we will also be competing with respect to manufacturing efficiency and marketing capabilities, areas in which we have limited experience. Our competitors may possess or obtain patent protection or other intellectual property rights that prevent, limit or otherwise adversely affect our ability to develop or exploit our products. We have limited manufacturing experience and capacity. Ampligen is currently produced only in limited quantities for use in our clinical trials and we are dependent upon certain third party suppliers for key components of our products and for substantially all of the production process. The failure to continue these arrangements or to achieve other such arrangements on satisfactory terms could have a material adverse affect on us. Also, to be successful, our products must be manufactured in commercial quantities in compliance with regulatory requirements and at acceptable costs. To the extent we are involved in the production process, our current facilities are not adequate for the production of our proposed products for large-scale commercialization, and we currently do not have adequate personnel to conduct commercial-scale manufacturing. We intend to utilize third-party facilities if and when the need arises or, if we are unable to do so, to build or acquire commercial-scale manufacturing facilities. We will need to comply with regulatory requirements for such facilities, including those of the FDA and HPB pertaining to current Good Manufacturing Practices ("cGMP") regulations. There can be no assurance that such facilities can be used, built, or acquired on commercially acceptable terms, or that such facilities, if used, built, or acquired, will be adequate for our long-term needs. We may be subject to product liability claims from the use of Ampligen or other of our products which could negatively affect our future operations. We face an inherent business risk of exposure to product liability claims in the event that the use of Ampligen or other of our products results in adverse 12 effects. This liability might result from claims made directly by patients, hospitals, clinics or other consumers, or by pharmaceutical companies or others manufacturing these products on our behalf. Our future operations may be negatively effected from the litigation costs, settlement expenses and lost product sales inherent to these claims. While we will continue to attempt to take appropriate precautions, we cannot assure that we will avoid significant product liability exposure. Although we currently maintain worldwide product liability insurance coverage, there can be no assurance that this insurance will provide adequate coverage against product liability claims. A successful product liability claim against us in excess of our insurance coverage or for which coverage is not provided could have a negative effect on our business and financial condition. Members of our Scientific Advisory Board may have conflicting interests and may disclose data and technical know how to our competitors. All of our Scientific Advisory Board members are employed by other entities, which may include our competitors. Although we require each of our Scientific Advisory Board members to sign a non-disclosure and non-competition agreement with respect to the data and information that he or she receives from us, we cannot assure you that members will abide by them. If a member were to reveal this information to outside sources, accidentally or otherwise, our operations could be negatively effected. Since our business depends in large part on our ability to keep our technical expertise confidential, any revelation of this information to a competitor or other source could have an adverse effect on our operations. There is no guarantee that our trade secrets will not be disclosed or known by our competitors. To protect our rights, we require certain employees and consultants to enter into confidentiality agreements with us. There can be no assurance that these agreements will not be breached, that we would have adequate and enforceable remedies for any breach, or that any trade secrets of ours will not otherwise become known or be independently developed by competitors. The loss of Dr. Carter's services could hurt our chances for success. Our success is dependent on the continued efforts of Dr. William A. Carter because of his position as a pioneer in the field of nucleic acid drugs, his being the co-inventor of Ampligen, and his knowledge of our overall activities, including patents, clinical trials, corporate relationships and relationships with governmental agencies which regulate our business. The loss of Dr. Carter's services could have a material adverse effect on our operations and chances for success. While we have an employment agreement 13 with Dr. Carter, and have secured key man life insurance in the amount of $2 million on the life of Dr. Carter, the loss of Dr. Carter or other personnel, or the failure to recruit additional personnel as needed could have a materially adverse effect on our ability to achieve our objectives. Uncertainty of health care reimbursement for our products. Our ability to successfully commercialize our products will depend, in part, on the extent to which reimbursement for the cost of such products and related treatment will be available from government health administration authorities, private health coverage insurers and other organizations. Significant uncertainty exists as to the reimbursement status of newly approved health care products, and from time to time legislation is proposed, which, if adopted, could further restrict the prices charged by and/or amounts reimbursable to manufacturers of pharmaceutical products. We cannot predict what, if any, legislation will ultimately be adopted or the impact of such legislation on us. There can be no assurance that third party insurance companies will allow us to charge and receive payments for products sufficient to realize an appropriate return on our investment in product development. There are risks of liabilities associated with handling and disposing of Hazardous materials. Our business involves the controlled use of hazardous materials, carcinogenic chemicals and various radioactive compounds. Although we believe that our safety procedures for handling and disposing of such materials comply in all material respects with the standards prescribed by applicable regulations, the risk of accidental contamination or injury from these materials cannot be completely eliminated. In the event of such an accident or the failure to comply with applicable regulations, we could be held liable for any damages that result, and any such liability could be significant. We do not maintain insurance coverage against such liabilities. The market price of our stock may be adversely affected by market volatility. The market price of our common stock has been and is likely to be volatile. In addition to general economic, political and market conditions, the price and trading volume of our stock could fluctuate widely in response to many factors, including: * announcements of the results of clinical trials by us or our competitors; * adverse reactions to products; 14 * governmental approvals, delays in expected governmental approvals or withdrawals of any prior governmental approvals or public or regulatory agency concerns regarding the safety or effectiveness of our products; * changes in U.S. or foreign regulatory policy during the period of product development; * developments in patent or other proprietary rights, including any third party challenges of our intellectual property rights; * announcements of technological innovations by us or our competitors; * announcements of new products or new contracts by us or our competitors; * actual or anticipated variations in our operating results due to the level of development expenses and other factors; * changes in financial estimates by securities analysts and whether our earnings meet or exceed the estimates; * conditions and trends in the pharmaceutical and other industries; * new accounting standards; and * the occurrence of any of the risks described in these "Risk Factors." Our common stock is listed for quotation on the American Stock Exchange. For the 12-month period ended December 31, 2002, the price of our common stock has ranged from $0.74 to $4.95. We expect the price of our common stock to remain volatile. The average daily trading volume in our common stock varies significantly. Our relatively low average volume and low average number of transactions per day may affect the ability of our stockholders to sell their shares in the public market at prevailing prices and a more active market may never develop. In the past, following periods of volatility in the market price of the securities of companies in our industry, securities class action litigation has often been instituted against companies in our industry. If we face securities litigation in the future, even if without merit or unsuccessful, it would result in substantial costs and a diversion of management attention and resources, which would negatively impact our business. Provisions of our Certificate of Incorporation and Delaware law could defer a change of our management which could discourage or delay offers to acquire us. Provisions of our Certificate of Incorporation and Delaware law may make it more difficult for someone to acquire control of us or for our stockholders to remove existing management, and might discourage a third party from offering to acquire us, even if a change in control or in management would be beneficial to our stockholders. For example, our Certificate of Incorporation allows us to issue shares of preferred stock without any vote or further action by our stockholders. Our Board of Directors has the authority to fix and determine the relative rights and preferences 15 of preferred stock. Our Board of Directors also has the authority to issue preferred stock without further stockholder approval. As a result, our Board of Directors could authorize the issuance of a series of preferred stock that would grant to holders the preferred right to our assets upon liquidation, the right to receive dividend payments before dividends are distributed to the holders of common stock and the right to the redemption of the shares, together with a premium, prior to the redemption of our common stock. In addition, our Board of Directors, without further stockholder approval, could issue large blocks of preferred stock. Because the risk factors referred to above could cause actual results or outcomes to differ materially from those expressed in any forward-looking statements made by us, you should not place undue reliance on any such forward-looking statements. Further, any forward-looking statement speaks only as of the date on which it is made and we undertake no obligation to update any forward-looking statement or statements to reflect events or circumstances after the date on which such statement is made or reflect the occurrence of unanticipated events. New factors emerge from time to time, and it is not possible for us to predict which will arise. In addition, we cannot assess the impact of each factor on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Our research in clinical efforts may continue for the next several years and we may continue to incur losses due to clinical costs incurred in the development of Ampligen for commercial application. Possible losses may fluctuate from quarter to quarter as a result of differences in the timing of significant expenses incurred and receipt of licensing fees and/or cost recovery treatment revenues in Europe, Canada and in the United States. Legal Proceedings On September 30, 1998, we filed a multi-count complaint against Manuel P. Asensio, Asensio & Company, Inc. ("Asensio"). The action included claims of defamation, disparagement, tortuous interference with existing and prospective business relations and conspiracy, arising out of the Asensio's false and defamatory statements. The complaint further alleged that Asensio defamed and disparaged us in furtherance of a manipulative, deceptive and unlawful short-selling scheme in August and September, 1998. In 1999, Asensio filed an answer and counterclaim alleging that in response to Asensio's strong sell recommendation and other press releases, we made defamatory statements about Asensio. We denied the material allegations of the counterclaim. In July 2000, following dismissal in federal court for lack of subject matter jurisdiction, we transferred the action to the Pennsylvania State Court. In March 2001, the defendants responded to the complaints as amended 16 and a trial commenced on January 30, 2002. A jury verdict disallowed the claims against the defendants for defamation and disparagement and the court granted us a directed verdict on the counterclaim. On July 2, 2002 the Court entered an order granting us a new trial against Asensio for defamation and disparagement. Thereafter, Asensio appealed the granting of a new trial. This appeal is now pending in the Superior Court of Pennsylvania. In June 2002, a former ME/CFS clinical trial patient and her husband filed a claim in the Superior Court of New Jersey, Middlesex County, against us, one of our clinical trial investigators and others alleging that she was harmed in the ME/CFS clinical trial as a result of negligence and breach of warranties. We believe the claim is without merit and we are defending the claim against us through our product liability insurance carrier. In June 2002, a former ME/CFS clinical trial patient in Belgium filed a claim in Belgium, against Hemispherx Biopharma Europe, NV/SA, our Belgian subsidiary, and one of our clinical trial investigators alleging that she was harmed in the Belgium ME/CFS clinical trial as a result of negligence and breach of warranties. We believe the claim is without merit and we are defending the claim against us through our product liability insurance carrier. In July 2002, we filed suit against Federal Insurance Company ("Federal") seeking (1) a judicial order declaring our rights and the obligations of Federal under the insurance policy Federal sold to us (2) monetary damage for breach of contract resulting from Federal's refusal to fully defend us in connection with the Asensio litigation (3) monetary damages to compensate us for Federal's breach of its fiduciary duty faith and dealing and (4) monetary damages, interest, costs, and attorneys fees to compensate us for Federal's violation of the Pennsylvania Bad Faith Statute. Our suit against Federal is now pending in the United States District Court for the Eastern District of Pennsylvania. Dividend Policy We have not paid any cash dividends since our inception and do not anticipate paying cash dividends in the foreseeable future. Selling Stockholders This prospectus relates to the proposed sale by us, agent or agents designated by us, or certain stockholders of * 499,996 warrants owned by the selling stockholders 17 * 499,996 shares of common stock underlying the selling stockholders' warrants and, * although not set forth in this part of the prospectus, this prospectus also relates to the registration of the sale by us of 5,000,000 shares of common stock. The following table sets forth as of the date of this prospectus certain information with respect to the selling stockholders. The information is based on information provided by or on behalf of the selling stockholders which include our Officers, Directors and Employees. The selling stockholders may offer all, some or none of their warrants and/or shares of our common stock. We will not receive any of the proceeds from the sale of the warrants or the resale of the shares of common stock underlying the warrants, which are included in this registration statement, for which this prospectus forms a part. We will however receive proceeds from our sale of shares of common stock and from the exercise of warrants, which are included in this registration statement, for which this prospectus forms a part. We believe, based on information supplied by the selling stockholders, that each of them has sole voting and investment power with respect to the shares of common stock owned by them or to be owned by them upon exercise of their warrants. For purposes of estimating the number of shares of common stock to be registered for resale by this prospectus, we include 499,996 shares, representing 100% of the shares of common stock issuable upon the exercise of the selling stockholder's warrants, without regard to any limitation on exercise. The fourth and fifth column below assumes the sale of all of the shares offered by each selling stockholder. Beneficial ownership is determined in accordance with the rules of the Securities and Exchange Commission and generally includes voting or investment power with respect to securities. It also includes shares of common stock which such person has the right to acquire within 60 days. Percentage calculations are based upon 32,623,476 shares of our common stock outstanding as of the date of the Prospectus. 18 Securities Securities Owned Prior Securities Owned To Offering Offered(1) After Offering =========== ================= ==================== ================= === Common Name of Stock Selling Common Underlying Common Stockholder Stock Warrants Warrants Warrants Stock Warrants % ----------- ------ --------- --------- ---------- ------ --------- --- Lawrence Zaslow --- 233,332 158,332(2) 158,332 0 75,000(3) * Peter Adolph --- 258,332 158,332(2) 158,332 0 100,000(3) * Mark Komorsky --- 258,332 158,332(2) 158,332 0 100,000(3) * Paul Michaels --- 100,000 25,000(4) 25,000 0 75,000(3) * --------------------------------------------------------------------------- (1) Assumes the sale of all securities offered.

You should rely only on the information incorporated by reference or provided in this prospectus or any supplement. We have not authorized anyone else to provide you with different information. We and the selling stockholders will not make offers to these shares in any state where the offer is not permitted. You should not assume that the information in this prospectus or any supplement is accurate as of any date other that the date on the front of those documents. Description of Securities The following section does not purport to be complete and is qualified in all respects by reference to the detailed provisions of our certificate of incorporation and by-laws, as amended, copies of which have been filed with the Securities and Exchange Commission. Our authorized capital stock consist of: (i) 50,000,000 shares of common stock, $.001 par value; and (ii) 5,000,000 shares of preferred stock, ..01 par value. 32,623,476 shares of common stock were issued and outstanding as of the date of this prospectus. As of this date, there were approximately 331 record holders of our common stock not including holders in street name. We estimate that there are some 3,300 holders if you include shares held in street name. Common Stock Shares of our common stock are entitled to one vote per share, either in person or by proxy, on all matters that may be voted upon by the owners of our shares at meetings of our stockholders. There is no provision for cumulative voting with respect to the election of directors by the holders of common stock. 21 Therefore, the holder of more than 50% of our shares of outstanding common stock can, if they choose to do so, elect all of our directors. In this event, the holders of the remaining shares of common stock will not be able to elect any directors. The holders of common stock: * have equal rights to dividends from funds legally available therefore, when and if declared by our board of directors; * are entitled to share ratably in all of our assets available for distribution to holders of common stock upon liquidation, dissolution or winding up of our affairs; and * do not have preemptive rights, conversion rights, or redemption of sinking fund provisions. The outstanding shares of our common stock are duly authorized, validly issued, fully paid and nonassessable. Preferred Stock. Under our certificate of incorporation, as amended, our board of directors is authorized, subject to certain limitations prescribed by law, without further stockholder approval, from time to time to issue up to an aggregate of 5,000,000 shares of preferred stock. At this time, there are no preferred shares outstanding. Warrants. We have issued the warrants to the selling stockholders at various times and over a period of years primarily in private unregistered transactions. The warrants are similar in form, terms and conditions. Generally, the warrants materially differ from each other only in the exercise price, duration of the exercise period, and commencement and expiration dates. The applicable prospectus supplement will describe, where applicable, the terms of each warrant in respect to which this prospectus is being delivered. 22 Plan of Distribution By Selling Stockholders The shares of our common stock offered by this prospectus may be sold from time to time by the selling stockholders, to purchasers directly by them in one or more transactions at a fixed price, which may be changed, or at varying prices determined at the time of sale or at negotiated prices. Such prices will be determined by the holders of such securities or by agreement between such holders and underwriters or dealers who may receive fees or commissions in connection with such sales. Each of the selling stockholders, may from time to time, offer shares of our common stock beneficially owned by them through underwriters, dealers or agents, who may receive compensation in the form of underwriting discounts, commissions or concessions from the selling stockholders and the purchasers of the shares for whom they may act as agent. Each of the selling stockholders will be responsible for payment of commissions, concessions and discounts of underwriters, dealers or agents. The aggregate proceeds to the selling stockholders, from the sale of the shares of our common stock offered by them will be the purchase price of such shares less discounts and commissions, if any. Each of the selling stockholders reserves the right to accept and, together with their agents, from time to time to reject, in whole or in part, any proposed purchase of shares to be made directly or through agents. Alternatively, the selling stockholders may sell all or a portion of the shares of our common stock beneficially owned by them and offered from time to time on any exchange on which the securities are listed on terms to be determined at the times of such sales. The selling stockholders may also make private sales directly or through a broker or brokers. From time to time, the selling stockholders may transfer, pledge, donate or assign shares of our common stock to lenders or others, and each of such persons will be deemed to be a "selling stockholder" for purposes of this prospectus. The number of shares beneficially owned by a selling stockholder who transfers, pledges, donates or assigns shares of our common stock will decrease as and when they take such actions. The plan of distribution for shares sold under this prospectus will otherwise remain unchanged, except that the transferees, pledgees, donees other successors will be selling stockholders under this prospectus and may sell their shares in the same manner as the selling stockholders. A selling stockholder may enter into hedging transactions with broker-dealers, and the broker dealers may engage in short sales of the shares of our common stock in the course of hedging the positions they assume with such selling stockholder, including in connection with distribution of the shares of our 23 common stock by such broker-dealers. In addition, a selling stockholder may, from time to time, sell short the shares of our common stock, and in such instances, this prospectus may be delivered in connection with such short sales and the shares offered may be used to cover such short sales. The selling stockholders may also enter into option or other transactions with broker-dealers that involve the delivery of the shares of our common stock to the broker-dealer, who may then resell or otherwise transfer such shares. The selling stockholders may also loan or pledge the shares to a broker-dealer and the broker-dealer may sell the shares as loaned or upon a default may sell or otherwise transfer the pledged shares. The selling stockholders and any underwriters, dealers or agents that participate in the distribution of the shares of our common stock offered by this prospectus may be deemed to be underwriters within the meaning of the Securities Act, and any discounts, commissions or concessions received by them and any provided pursuant to the sale of shares by them might be deemed to be underwriting discounts and commissions under the Securities Act. In addition, any securities covered by this prospectus, which qualify for sale pursuant to Rule 144 or Rule 144A of the Securities act, may be sold under Rule 144 or Rule 144A rather than pursuant to this prospectus. There is no assurance that any selling stockholder will sell any or all of the shares of our common stock described in this prospectus, and any selling stockholder may transfer, devise or gift such securities by other means not described in this prospectus. If necessary, the specific shares of our common stock to be sold in this prospectus, the names of the selling stockholders, the respective purchase prices and public offering prices, the names of any agent, dealer or underwriter, and any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement of which this prospectus is a part. We will pay substantially all of the expenses incurred by the selling stockholders and us incident to the offering and sale of the shares of our common stock issuable upon exercise of the warrants, excluding any underwriting discounts or commissions. We will not receive proceeds from the resale of our stockholders' shares issuable upon exercise of our warrants; however, we may receive proceeds from our sale of our securities and from the exercise of our warrants. By us We may sell the shares offered by us pursuant to this prospectus (Offered Shares) in one or more series in any of three ways: (1) through underwriters or 24 dealers; (2) through agents; or (3) directly to a limited number of purchasers or to a single purchaser. THROUGH UNDERWRITERS OR DEALERS. If underwriters are used in the sale, the Offered Shares may be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at varying prices determined at the time of the sale. The Offered Shares may be offered to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more managing underwriters. The underwriter or underwriters with respect to Offered Shares will be named in the prospectus supplement relating to such offering and, if an underwriting syndicate is used, the managing underwriter or underwriters will be set forth on the cover page of such prospectus supplement. Such prospectus supplement shall state the obligations of the underwriters to purchase the Offered Securities, whether such purchases will be subject to certain conditions precedent, and whether the underwriters will be obligated to purchase all of the Offered Shares if any are purchased. THROUGH AGENTS. Offered Shares may be sold through agents designated by us from time to time. A prospectus supplement will set forth the name of any agent involved in the offer or sale of the Offered Shares in respect of which such prospectus supplement is delivered as well as any commissions payable by us to such agent. Unless otherwise indicated in such prospectus supp*lement, any such agent will be acting on a reasonable best efforts basis for the period of its appointment. DIRECTLY. We may sell the Offered Shares directly to one or more purchasers. In this case, no underwriters or agents would be involved. GENERAL INFORMATION. The prospectus supplement with respect to the Offered Shares will set forth the terms of the offering of such Offered Shares, including: * the name or names of any underwriters, dealers or agents; * the purchase price of such Offered Shares and the proceeds to us from such sale; * any underwriting discounts, agents' commissions and other items constituting underwriting compensation; * any initial public offering price; and 25 * any discounts or concessions allowed or reallowed or paid to dealers. Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time. Agents, underwriters and dealers may be entitled under agreements entered into with us to indemnification by us against certain civil liabilities, including certain liabilities under the Securities Act of 1933 or to contribution by us with respect to payments which such agents, underwriters and dealers may be required to make in respect thereof.

ITEM 17. UNDERTAKINGS (a) Insofar as indemnification for liabilities arising under the Securities Act of 1933 (the "Securities Act") may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. (b) The undersigned registrant hereby undertakes that for purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) We, the undersigned Registrant hereby undertake: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to the Registrant Statement to: (i) Include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; 30 (ii) Reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) that individually or in the aggregate represent a fundamental change in the information set forth in the Registration Statement; and (iii) Include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement; provided, however, that paragraphs (i) and (ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the Registration Statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post- effective amendment any of the securities being registered which remain unsold at the termination of the offering. 31 SIGNATURES Pursuant to the requirement of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized in the City of Philadelphia, Commonwealth of Pennsylvania, on the 8 th day of January, 2003.

We have also examined certificates of the Company's officers and of public officials, and have reviewed such questions of law and made such other inquiries, as we have deemed necessary or appropriate for the purpose of rendering this opinion.

Based on and subject to the assumptions, qualifications and limitations set forth herein, we are of the opinion that: 1. The Shares have been duly and validly authorized for issuance and, when issued and delivered in the manner described in the Registration Statement against full payment of the consideration set forth therein, will be validly issued, fully paid and nonassessable. 2. The Warrant Shares have been duly authorized for issuance pursuant to the Warrants, and when issued and delivered in the manner described in the Warrants against full payment of the consideration set forth therein, will be validly issued, fully paid and nonassessable. 3.
