PART I Item 1. Business (a) General Development of Business Agreement with Hemispherx Biopharma, Inc. ("HEB") On March 11, 2003, Interferon Sciences, Inc. ("ISI" or the "Company") executed two agreements with HEB to sell certain assets of ISI (the two asset sale transactions are hereinafter jointly referred to as the "Asset Sale Transactions" and individually referred to as the "First Asset Sale" and the "Second Asset Sale") and consummated the First Asset Sale. In the first agreement with HEB (the "First Asset Sale Agreement"), ISI sold all of its inventory related to ALFERON N Injection(R), ISI's natural alpha interferon product approved for the treatment of certain types of genital warts (the "Product"), and granted a limited license for the production, manufacture, use, marketing and sale of the Product in the United States. For these assets, ISI: (i) received 424,528 shares of HEB common stock (the "Common Stock") (these shares, along with other shares described below as having a guaranteed value, are sometimes referred to as the "Guaranteed Shares") which had a Market Value (as defined in the First Asset Sale Agreement) of $675,000 and a guaranteed value of $675,000; (ii) received an additional 62,500 shares of Common Stock without a guaranteed value; and (iii)will receive a royalty equal to 6% of the net sales of the Product. ISI will receive a service fee for providing certain transitional services. In addition, HEB will assume ISI payables and certain other obligations related to the Product. This Agreement obligates HEB to register the Common Stock issued to ISI, sets periodic limits on the number of shares ISI may sell and requires HEB to pay ISI an amount equal to the product received by multiplying (i) the number of Guaranteed Shares remaining unsold on March 11, 2005 and (ii) $1.59. The remaining Guaranteed Shares will then be returned to HEB. In the second agreement with ISI (the "Second Asset Sale Agreement"), ISI has agreed to sell, subject to certain approvals, to HEB all of its rights to the Product and other assets related to the Product including, but not limited to, real estate and machinery. For these assets, ISI will: (i) receive 424,528 shares of HEB Common Stock which has a Market Value (as defined in the Second Asset Sale Agreement) of $675,000 and a guaranteed value of $675,000; (ii) receive an additional 62,500 shares of HEB Common Stock without a guaranteed value; and (iii)receive a royalty equal to 6% of the net sales of any products containing natural alpha interferon sold by HEB (or a Marketing Partner, as defined in the Second Asset Sale Agreement) In addition, HEB will be required to satisfy three obligations of ISI which aggregate approximately $1,500,000. HEB will be obligated to pay certain ongoing expenses related to ISI's operations prior to the closing of the Second Asset Sale Agreement. The Second Asset Sale Agreement obligates HEB to register the Common Stock to be issued, sets periodic limits on the number of these shares that may be sold and requires HEB to pay ISI an amount equal to the product received by multiplying (i) the number of Guaranteed Shares remaining unsold on the date which is two years after the closing date of the Second Asset Sale Agreement and (ii) $ 1.59. The remaining Guaranteed Shares will then be returned to HEB. The purchase price for the assets was determined by negotiation between HEB and ISI. The foregoing descriptions of the Asset Sale Transactions, the First Asset Sale Agreement and the Second Asset Sale Agreement are qualified in their entirety by reference to the full text of the First Asset Sale Agreement, the Second Asset Sale Agreement, which are filed as Exhibits 2.1 and 2.2 to the Current Report on Form 8-K, dated March 18, 2003, and incorporated herein by reference. Set forth below is a description of the business related to ALFERON N Injection which was sold to HEB. Interferon Sciences, Inc. (the "Company") is a biopharmaceutical company which studies, manufactures, and sells ALFERON N Injection(R), a pharmaceutical product based on its highly purified, multi-species, natural-source alpha interferon ("Natural Alpha Interferon"). ALFERON N Injection (Interferon Alfa-n3) is approved by the United States Food and Drug Administration ("FDA") for the treatment of certain types of genital warts and we have studied its potential use in the treatment of human immunodeficiency virus ("HIV"), hepatitis C virus ("HCV"), and other indications. ALFERON N Injection is currently being studied in cancer and we are also evaluating its use in the treatment of multiple sclerosis and certain other viral diseases. (b) Financial Information about Business Segments The Company operates as a single line of business. For the years ended December 31, 2002, 2001 and 2000, domestic sales totaled $1,926,466, $1,488,897 and $1,046,470, respectively and foreign sales totaled $-0-, $9,706 and $21,001, respectively. All identifiable assets are located in the United States. (c) Narrative Description of Business Scientific Background Interferons are a group of proteins produced and secreted by cells to combat diseases. Researchers have identified four major classes of human interferon: alpha, beta, gamma and omega. The Company's ALFERON N Injection product contains a multi-species form of alpha interferon. The worldwide market for injectable alpha interferon-based products has experienced rapid growth and various alpha interferon injectable products are approved for many major medical uses worldwide. Alpha interferons are manufactured commercially in three ways: by genetic engineering, by cell culture, and from human white blood cells. In the United States, all three of these types of alpha interferon are approved for commercial sale. The Company's Natural Alpha Interferon is produced from human white blood cells. The Company believes that the potential advantages of Natural Alpha Interferon over recombinant interferons may be based upon their respective molecular compositions. Natural Alpha Interferon is composed of a family of proteins containing many different molecular species of interferon. In contrast, recombinant alpha interferons each contain only a single species. Researchers have reported that the various species of interferon may have differing antiviral activity depending upon the type of virus. Natural Alpha Interferon presents a broad complement of species which the Company believes may account for its higher efficacy in laboratory studies with the HIV virus compared with that of recombinant alpha interferon 2a and 2b (ROFERON(R) A and INTRON(R) A, respectively). Natural Alpha Interferon is also glycosylated (partially covered with sugar molecules). Such glycosylation is not present on the currently marketed recombinant alpha interferons. The Company believes that the absence of glycosylation may be, in part, responsible for the production of interferon-neutralizing antibodies seen in patients treated with recombinant alpha interferon. Although cell culture-derived interferon is also composed of multiple glycosylated alpha interferon species, the types and relative quantity of these species are different from the Company's Natural Alpha Interferon. The production of Natural Alpha Interferon is dependent upon a supply of human white blood cells and other essential materials. The Company obtains white blood cells from FDA- licensed blood donor centers. ALFERON N Injection Approved Indication. On October 10, 1989, the FDA approved ALFERON N Injection for the intralesional treatment of refractory (resistant to other treatment) or recurring external genital warts in patients 18 years of age or older. Substantially all of the Company's revenues, to date, have been generated from the sale of ALFERON N Injection for such treatment. Certain types of human papillomaviruses ("HPV") cause genital warts, a sexually transmitted disease. A published report estimates that approximately eight million new and recurrent cases of genital warts occur annually in the United States alone. Genital warts are usually treated using caustic chemicals or through physical removal methods. These procedures can be quite painful and effective treatment outcomes are often difficult to achieve. The FDA approved a topical formulation of an interferon-inducer in 1997 for the treatment of genital warts. To date, the Company does not believe that such approval has had a material adverse effect on the sales of ALFERON N Injection. Clinical Trials for New Indications. In an effort to obtain approval to market ALFERON N Injection for additional indications, the Company has conducted various clinical trials for new indications. HIV-infected Patients. The Human Immunodeficiency Virus ("HIV") infection is at epidemic levels in the world. It currently affects approximately 40 million people. HIV infection usually signals the start of a progressive disease that compromises the immune system, ultimately resulting in Acquired Immune Deficiency Syndrome ("AIDS"). An article published in AIDS Research and Human Retroviruses in 1993 by investigators at Walter Reed Army Institute of Research ("Walter Reed") in collaboration with the Company's scientists indicated that the various interferon species display vast differences in their ability to affect virus replication. Walter Reed researchers found that the Company's Natural Alpha Interferon was approximately 10 to 100 times more effective than equal concentrations of recombinant alpha interferon 2a or 2b, in blocking the replication of HIV-1, the AIDS virus, in infected human cells (monocytes) in vitro. Moreover, the Company's scientists were able to separate members of the interferon family in single protein fractions or clusters of proteins using advanced fractionation techniques. The individual fractions were tested for their ability to block HIV replication in the laboratory by researchers at Walter Reed. They found that the unusual anti-HIV activity was attributable to very specific fractions in the Company's product. The most active fractions are not present in marketed recombinant interferon products. This information provided additional support for a long-held belief of the Company that its Natural Alpha Interferon has unique anti-viral properties distinguishing it from recombinant interferon products. In addition, published reports of trials using recombinant alpha interferon in asymptomatic HIV-infected patients indicated that while high doses blocked virus production in many cases, such doses resulted in high levels of adverse reactions, thereby limiting the usefulness of the recombinant product. These facts led the Walter Reed researchers to conduct a Phase 1 clinical trial with the Company's product in asymptomatic HIV-infected patients. In March 1992, Walter Reed launched a Phase 1 clinical trial in asymptomatic HIV-infected patients with CD4 white blood cell counts of at least 400 cells per cubic millimeter, to investigate the safety and tolerance, at several dose regimens, of ALFERON N Injection, self-injected subcutaneously for periods of up to 24 weeks. The investigators concluded that the treatment was "surprisingly" well tolerated by patients, at all dose regimens. Preliminary findings were reported by Walter Reed at the IXth International Conference on AIDS in Berlin in 1993. The investigators also reported that the expected interferon side effects, such as flu-like symptoms, were rare or absent in the majority of patients treated with the Company's product. Although this Phase 1 clinical trial was designed primarily to provide safety information on various doses of ALFERON N Injection used for extended periods of time, there were encouraging indications that certain disease parameters had stabilized or even improved in certain patients by the end of the experimental treatment. In a follow-up analysis of patients' blood testing data, it was found that while on treatment, the amount of HIV detectable in the patients' blood, as measured by polymerase chain reaction ("PCR") testing, declined in a dose dependent manner (the greatest declines were observed in the highest dose group). Also, none of the patients were found to have developed neutralizing antibodies to Natural Alpha Interferon, even after being treated three times weekly for many months. These results were reported at the Third International Congress on Biological Response Modifiers held in Cancun, Mexico in January 1995 and were selected for a poster presentation at the 35th Interscience Conference on Antimicrobial Agents and Chemotherapy held in San Francisco in September 1995. An extensive report was published in the May 1996 issue of the Journal of Infectious Diseases. It is important to note that, because of the small number of study participants and the absence of a control group, no firm conclusions can be drawn from these observations. However, based on the safety and preliminary efficacy data obtained from this trial and after meeting with the FDA, the Company conducted a multi-center Phase 3 clinical trial of ALFERON N Injection in HIV-infected patients, which was completed in December 1997. This randomized, double-blind, placebo-controlled trial was designed to evaluate the safety and efficacy of ALFERON N Injection in the treatment of HIV-positive patients, some of whom may have been taking other FDA-approved antiviral agents. Enrolled patients were required to have CD4 white blood cell counts of at least 250 cells per cubic millimeter and a viral burden (as determined by PCR testing) of at least 2,000 RNA copies per milliliter. The Company completed the analysis of the data collected from the 16 investigator sites and attended a pre-filing meeting with the FDA in mid-March 1998. Shortly after that meeting, the FDA advised the Company that, although ALFERON N Injection demonstrated biological activity in this Phase 3 clinical trial, the results were insufficient for filing for approval for this additional indication for ALFERON N Injection. While the results over the course of treatment demonstrated benefits that were statistically significant for the group of patients receiving ALFERON N Injection and highly statistically significant for the subgroup of patients with high CD4 white blood cell counts (CD4 counts of at least 400 cells per cubic millimeter, as was studied in the Phase 1 study above), the study's primary efficacy variable (reduction in viral load) was not met at the time point specified in the protocol (end of treatment). Because the agreed upon primary endpoint was not met and in light of the changes in HIV treatment regimen to simultaneous multiple drug therapy since this trial was designed, the FDA indicated that an additional trial, in which ALFERON N Injection was studied in conjunction with multiple drug therapy would be necessary to evaluate further the efficacy of ALFERON N Injection for this indication. Hepatitis C. Chronic viral hepatitis is a liver infection caused by various hepatitis viruses. The United States Centers for Disease Control and Prevention estimates that nearly four million people in the United States are presently infected with the hepatitis C virus ("HCV"), a majority of who become chronic carriers and will suffer gradual deterioration of their liver and possibly cancer of the liver. Several brands of recombinant interferon and a cell-cultured interferon have been approved for the treatment of hepatitis C infection in the United States and by various regulatory agencies worldwide. See "Business - ALFERON N Injection - Competition." However, reports have indicated that many patients either do not respond to treatment with the recombinant products or relapse after treatment. The Company has conducted three multi-center, randomized, open-label, dose ranging Phase 2 clinical trials utilizing ALFERON N Injection with patients chronically infected with HCV. The objective of the Company's HCV clinical studies was to compare the safety and efficacy of different doses of Natural Alpha Interferon injected subcutaneously in naive (previously untreated), refractory (unsuccessfully treated with recombinant interferon), and relapsing (initially responded to recombinant interferon but later relapsed) patients. The results in naive patients indicated a significant dose-dependent response at the end of treatment favoring the highest dose group. In addition, treatment of naive patients with ALFERON N Injection did not produce any interferon-neutralizing antibodies. An oral presentation of the results in naive patients was given at the American Association for the Study of Liver Diseases ("AASLD") meeting that took place in November 1995. The results of this study were published in the February 1997 issue of Hepatology. The results in refractory patients indicated a significant dose-dependent response at the end of treatment favoring the highest dose group. A poster presentation of the results in refractory patients was given at the AASLD meeting that took place in November 1995. Based on the promising results obtained in the study on naive patients, the study on relapsing patients, which was accruing patients slowly, was terminated early so that the Company could concentrate its limited resources on pursuing the Phase 3 trials in naive patients, discussed below. After meeting with the FDA, the Company commenced in 1996 a Phase 3 multi-center, open label, randomized, controlled clinical trial designed to evaluate the safety and efficacy of ALFERON N Injection compared to INTRON A in naive chronic hepatitis C patients. The trial was conducted at 26 sites located in the United States and Canada and a total of 321 people were treated. The trial consisted of a 24-week treatment phase and 24-week follow-up and also included an interim analysis after approximately one-half of the enrolled patients completed the treatment and follow-up phases. On April 2, 1998, the Company announced it had completed the interim analysis of the results for approximately half of the enrolled patients. If the results of the interim analysis had demonstrated at a very high level of statistical significance that ALFERON N Injection is effective, the Company intended to seek FDA approval while continuing to follow the other enrolled patients. However, while the efficacy analysis indicated that ALFERON N Injection and the control treatment (an approved therapy) appeared to yield similar results, the study protocol required a showing of superiority in order to meet the criteria for statistical significance in the interim analysis. Therefore, the Company did not seek FDA approval based on the interim analysis. The Phase 3 study was completed in 1998. The Company completed the final analysis of the data in March 1999, and met with the FDA to determine the acceptability of the results for filing purposes. At that meeting, the FDA advised the Company that the results of the trial were insufficient to file for approval because the designed endpoint of the trial (which required a showing of superiority in sustained normalization of liver enzymes at the end of treatment and after six months of follow up) was not met. Therefore, the FDA informed the Company that an additional trial would be required to further evaluate the efficacy of ALFERON N Injection for this indication. HIV and Hepatitis C Co-Infected Patients. In December 1997, patient enrollment commenced in a Phase 2 multi-center, open label clinical trial designed to evaluate the safety and efficacy of ALFERON N Injection in patients co-infected with HIV and HCV. In May 2000, an abstract entitled "Treatment of HCV/HIV Coinfection with Leukocyte Derived Interferon Alfa-n3", was published in Gastroenterology. Multiple Sclerosis. Multiple sclerosis ("MS") is a chronic, sometimes progressive, immune-mediated disease of the central nervous system that is believed to occur in genetically predisposed individuals following exposure to an environmental factor, such as virus infection. The disease affects an estimated 250,000 to 350,000 people in the United States, primarily young adults. Symptoms of MS, including vision problems, muscle weakness, slurred speech, and poor coordination, are believed to occur when the patient's own cells attack and ultimately destroy the insulating myelin sheath surrounding the brain and spinal cord nerve fibers, resulting in improper transmission of signals throughout the nervous system. In the United States, two recombinant forms of beta interferon have been approved for the treatment of relapsing-remitting MS. However, reports in the scientific literature and elsewhere have indicated that the significant adverse reactions associated with the treatments may limit their usefulness for a subset of patients. In addition, Teva Neuroscience, Inc.'s product, Copaxone(R), a non-interferon product, was approved by the FDA to treat relapsing-remitting MS. The Company has received anecdotal reports on the use of ALFERON N Injection in MS patients. In addition, encouraging reports were presented at a number of scientific conferences, namely: "Management of Interferon-(beta)1b (Betaseron) Failures in MS with Interferon-(alpha)n3 (Alferon N)", Charcot Foundation Meeting, Switzerland, March 2000, "Interferon-alfa-n3 (Alferon N) Reduces Gadolinium Enhancing Brain Lesions in Multiple Sclerosis", XVII World Congress of Neurology, London, UK, June 2001, "Alferon N (IFN-alfa-n3) and Betaseron (IFN-beta-1b) reduce T2 lesion load in multiple sclerosis (MS)", 17th Congress of the European Committee for Treatment & Research in Multiple Sclerosis (ECTRIMS), Dublin, Ireland, September 2001, and "Response of MR T2 Lesion Load in Patients with Multiple Sclerosis: A Retrospective Blinded Study of Treatment with Interferon (beta)1b (Betaseron) versus Interferon (alpha)-n3 (Alferon N) versus Untreated", 126th Annual Meeting of The American Neurological Association, in Chicago, October 2001. This last study was based on the retrospective review of multiple brain magnetic resonance imaging (MRI) scans to assess MS brain lesion burden. The study compared the scans of 40 MS patients treated with interferon alfa-n3 (ALFERON N Injection) as well as 40 MS patients treated with interferon beta-1b (Betaseron(R)), both before therapy and at least six months after initiation of therapy. A control group of 39 untreated MS patient scans were also evaluated with an initial MRI scan at baseline and a second MRI obtained at least six months after the baseline examination. On the 238 scans evaluated (119 patients) only lesions of larger than 5 mm3 were measured to avoid inclusion of potential non-MS lesions and assure accuracy of measurement. All scans were reviewed by consensus of two experienced neuroradiologists who were blinded to all identifiers, including name, date, order of scans, and clinical status of the patient. The study data showed a reduction in the volume of T2-weighted MS brain lesions in both the interferon alfa-n3 treated group (-10%) and the interferon beta-1b treated group (-7%), as compared to increased lesion volume in the untreated control group (+12%). Changes in disability scores amongst the groups were also retrospectively reviewed, based on the extended disability status scale (EDSS). Only patients with EDSS scores recorded both at baseline and after at least 12 months were evaluated, which included 38 interferon alfa-n3 treated patients, 31 interferon beta-1b treated patients, and 33 untreated patients. The results showed the mean absolute change in EDSS scores from baseline to be -1.07 for interferon alfa-n3 treated patients and -0.16 for interferon beta-1b treated patients after 12 months, as compared to +0.80 for untreated patients (negative changes reflect decreased disability scores, positive change reflects increased disability scores). The scale of EDSS scores ranges from 0 for a normal neurological examination to a score of 10 for death due to MS. This retrospective evaluation does not constitute a prospective clinical study of the type needed to obtain regulatory approval, and does not indicate that interferon alfa-n3 will be shown to be effective if such clinical studies are performed. Cancer. On April 30, 2001, the Company signed an exclusive technology license agreement with Mayo Foundation for Medical Education and Research, of Rochester, MN, for the rights to technology under investigation for preventing the recurrence of cancer after surgical removal of tumors. As part of the collaboration with Mayo, Interferon Sciences is funding a clinical trial entitled "Identification of an Immunostimulatory Dose of Natural Interferon (Phase A) and Its Impact on Clinical Outcome (Phase B) in Patients with Melanoma", which commenced in December 2001. The Company has committed to fund approximately $400,000 of costs related to this clinical trial. The Company paid Mayo $100,000 related to this clinical trial in 2001 and will owe other amounts upon the completion of certain parts of the trial, with the last payment due upon receipt of the final written report on the trial. The Company can terminate this agreement up to 60 days after receipt of this report. After expiration of this ability to terminate, the Company must issue 25,000 shares of the Company's common stock to Mayo and must pay milestone payments upon certain regulatory or other events and royalties on future sales, if any. In addition, the Company paid $60,000 to Mayo related to the agreement in 2001. The Company's right to continue this agreement was transferred to Hemispherx. See "Business - General Development of the Business - Agreement with Hemispherx Biopharma, Inc." This new approach to cancer therapy being studied at Mayo is referred to as neo-adjuvant immunotherapy with interferon. The goal of this approach, which uses a short duration interferon pretreatment, is to stimulate the innate immune system prior to surgical treatment. This is believed to be particularly appropriate in light of literature reports of the possible existence of postoperative anesthesia-induced immunosuppression. This neo-adjuvant approach is based upon the research in mice with implanted melanoma. In this study it was found that a short duration treatment with natural mouse leukocyte interferon prior to surgery significantly increased the survival rate compared to untreated controls (56% vs. 0%). In addition, at the end of the study, no evidence of metastatic tumors was found in the surviving mice. Animals treated with interferon for the same duration immediately after surgery (adjuvant therapy) did no better than the untreated controls. It is unknown whether comparable results can be achieved in humans. Marketing and Distribution. The Company does not have a marketing and sales force or an agreement with another company to carry out this function. In June 1998, the Company entered into an agreement with Integrated Commercialization Solutions, Inc. ("ICS"), a subsidiary of AmerisourceBergen Corporation, pursuant to which ICS became the sole United States distributor of ALFERON N Injection. ICS distributes ALFERON N Injection to wholesalers throughout the United States. The Company does not believe that the loss of any one wholesaler would have a material adverse effect on the Company's sales or financial position. ICS also provides clinical and product information, reimbursement information and services, and management of patient assistant services. However they do not market the product. At the present time the Company is dependent upon orders being received from the marketplace and processed by ICS. Substantially all of the revenues are derived from the sales of ALFERON N Injection in the United States. Manufacturing. The purified drug concentrate utilized in the formulation of ALFERON N Injection is manufactured in the Company's facility located in New Brunswick, New Jersey, and ALFERON N Injection is formulated and packaged at a production facility located in McPherson, Kansas and operated by Abbott. In April 1998 the Company discontinued the first stage of interferon production because it had produced sufficient inventories of interferon intermediates to satisfy its commercial needs. The Company has been converting and intends to continue to convert intermediates to finished product as needed. See "Management's Discussion and Analysis of Financial Condition and Results of Operations," "Business - ALFERON N Injection - Clinical Trials for New Indications," "Business - Governmental Regulation," and "Properties." Competition. Presently, INTRON A, manufactured by Schering, is the one other injectable interferon product approved by the FDA for the treatment of genital warts. INTRON A is made from recombinant alpha interferon. Since the production of INTRON A is not dependent on a source of human blood cells, it may be able to be produced in greater volume and at a lower cost than ALFERON N Injection. Currently, the Company's wholesale price on a per unit basis of ALFERON N Injection is substantially higher than that of INTRON A. In 1997, 3M Pharmaceuticals received FDA approval for its immune-response modifier, Aldara(R), a self-administered topical cream, for the treatment of external genital and perianal warts. ALFERON N Injection also competes with surgical, chemical, and other methods of treating genital warts. The Company cannot assess the impact from products developed by the Company's competitors or advances in other methods of the treatment of genital warts on the commercial viability of its product. If and when the Company obtains approvals for additional indications of ALFERON N Injection, it expects to compete primarily on the basis of product performance and price with a number of pharmaceutical companies, both in the United States and abroad. In the United States, two recombinant forms of beta interferon, Biogen, Inc.'s Avonex(R) and Berlex Laboratories' Betaseron(R) as well as Teva Neuroscience, Inc.'s Copaxone(R), a non-interferon product, have been approved for the treatment of relapsing-remitting MS. In addition, Immunex Corporation's Novantrone(R) was approved by the FDA in 2000 for reducing neurological disability and/or the frequency of clinical relapses in patients with secondary (chronic) progressive, progressive relapsing or worsening relapsing-remitting MS. Many of the Company's potential competitors are among the largest pharmaceutical companies in the world, are well known to the public and the medical community, and have substantially greater financial resources and product development, manufacturing, and marketing capabilities than the Company or its marketing partners. Therefore, there can be no assurance that, if the Company is able to obtain regulatory approval of ALFERON N Injection for the treatment of any additional diseases, it will be able to achieve any significant penetration into those markets. Licenses and Royalty Obligations The Company agreed to pay GP Strategies Corporation ("GP Strategies") a royalty of $1 million in connection with the acquisition of certain intellectual property and technology rights from GP Strategies. Such amount is payable if and when the Company generates income before taxes, limited to 25% of such income before income taxes per year until the amount is paid in full. To date, the Company has not generated income before taxes and therefore has not paid royalties to GP Strategies. Investments Metacine, Inc. On July 28, 2000, the Company acquired for $100,000 an option to purchase certain securities of Metacine, Inc. ("Metacine"), a company engaged in research using dendritic cell technology, on the terms set forth below. On April 9, 2001, the Company exercised its option to acquire an 82% equity interest in Metacine. Pursuant to the agreement, as amended, the Company received 700,000 shares of Metacine common stock and a five-year warrant to purchase, at a price of $12.48 per share, 282,794 shares of Metacine common stock in exchange for $300,000 in cash, an obligation to pay Metacine $ 1,850,000 and $250,000 of services to be rendered by the Company by June 30, 2002. In addition, the Company issued Metacine 2,000,000 shares of the Company's common stock. The agreement contains certain restrictions on the ability of Metacine to sell the Company's shares and provides for the Company to make cash payments ("Deficiency Payments") to Metacine to the extent Metacine has not received from the sale of the Company's common stock, cumulative net proceeds of $1,850,000 by September 30, 2002 or $400,000 of net proceeds per quarter beginning with the period ending September 30, 2001 and $250,000 for the quarter ending September 30, 2002. On October 4, 2001, the Company made a Deficiency Payment to Metacine in the amount of $400,000 for the quarter ending September 30, 2001. The Company has not made the remainder of the Deficiency Payments in the aggregate amount of $1,450,000. If Metacine sells all of the 2,000,000 shares received and the cumulative proceeds from the sales and any Deficiency Payments are less than $1,850,000, the Company may issue to Metacine additional shares of common stock at the Company's full discretion. These additional shares would be treated in the same manner as the original 2,000,000 shares. In the event that cumulative net proceeds to Metacine from the sale of the Company's common stock exceed $1,850,000, any Deficiency Payments previously made by the Company ($400,000 through December 31, 2002) would be repaid to the Company to the extent these proceeds exceed $1,850,000. All additional proceeds beyond the $1,850,000 and repayment of Deficiency Payments, if any, would be for the benefit of Metacine. The Company was required to put in escrow 100,000 Metacine shares to secure its obligations to render $250,000 of services to Metacine and 462,500 Metacine shares to secure its potential obligations to make Deficiency Payments. Since the Company has not made $1,450,000 in Deficiency Payments and has not rendered $250,000 of services to Metcine, Metacine could request 462,500 Metacine shares currently held in escrow to satisfy the Company's past due obligations. Although the Company is the majority owner of Metacine, the Company must, on many matters, vote its shares of Metacine common stock in the same proportion as votes cast by the minority stockholders of Metacine, except for certain matters with respect for which the Company has protective rights. In accordance with EITF Issue No. 96-16, Investor's Accounting for an Investee When the Investor has a Majority of the Voting Interest but the Minority Shareholder or Shareholders have Certain Approval or Veto Rights, the minority holders have substantive participating rights which include controlling the selection, termination and setting of compensation for Metacine management who are responsible for implementing policies and procedures, making operating and capital decisions (including establishing budgets) for Metacine and most other ordinary operating matters, and therefore, the Company does not control Metacine. In addition, the Company only has one representative on a board of directors consisting of three directors. Accordingly, the acquisition is being accounted for under the equity method. Of the $2.5 million consideration paid for Metacine, $2,341,418 was recorded as a charge for the acquisition of in-process research and development ("IPR&D") in 2001. The charge was recorded as the acquisition of IPR&D as Metacine's primary asset is technology that has not reached technological feasibility and has no alternative uses. The in-process research and development expenses relate to a patent portfolio consisting of six issued patents, eight pending patents and four invention disclosures related to the use of dendritic cells for the treatment of various diseases. While the patent portfolio, when viewed as a whole, represented a new approach to the treatment of various diseases utilizing cell therapy, the six issued patents had no independent commercial value. While the Company did not engage the services of an independent appraiser to assess the fair value of the purchased in process research and development, it considered the following factors: (i) any product or process utilizing dendritic cells as a treatment for any disease would regulated by the FDA and therefore would require extensive clinical testing prior to the time any revenue would be generate from the sale of a product or process, (ii) the cost of such clinical trials would be in excess of $ 50,000,000, (iii) it would take between seven to ten years to complete such clinical trials, (iv) there could be no assurance that even if Metacine could obtain the funding required to complete the clinical trials (which was well beyond Metacine's capability at the time Metacine acquired rights to the patent portfolio), that the clinical trials would have shown the product or process tested to be safe and effective. The Company's $1,850,000 obligation to Metacine, less the $400,000 Deficiency Payment made in October 2001, has been recorded as a current liability at December 31, 2002 and 2001. The $250,000 of services to be provided has also been recorded as a current liability. Services rendered to Metacine to date were immaterial and as such, the liability remained unchanged at December 31, 2002 and 2001. The investment has been further reduced to zero at December 31, 2001, by the Company's equity in the loss of Metacine of $158,582 for the period from April 9, 2001 through December 31, 2001. On April 1, 2003, the license granted by the University of Pittsburgh to Metacine covering Metacine's technology was terminated due to non-payment by Metacine. Accordingly, the Company's has not reflected its share of its equity in the losses in Metacine for the years ended December 31, 2002 and 2001 in the amounts of $274,846 and $290,994, respectively. The Company is currently in discussions with Metacine with respect to a full settlement of the Company's obligations to Metacine. Governmental Regulation Regulations imposed by U.S. federal, state, and local authorities, as well as their counterparts in other countries, are a significant factor in the conduct of the research, development, manufacturing, and marketing activities for present and proposed products developed by the Company. The Company's or its licensees' potential products will require regulatory approval by governmental agencies prior to commercialization. In particular, human medical products are subject to rigorous pre-clinical and clinical testing and other approval procedures by the FDA in the United States and similar health authorities in foreign countries. Various federal and, in some cases, state statutes and regulations also govern or influence the manufacturing, safety, labeling, storage, record keeping, and marketing of such products, including the use, manufacture, storage, handling, and disposal of hazardous materials and certain waste products. The process of obtaining these approvals and the subsequent compliance with applicable federal and foreign statutes and regulations involves a time-consuming process and requires the expenditure of substantial resources. The effect of government regulation may be to delay for a considerable period of time or prevent the marketing of any product that the Company may develop and/or impose costly procedures on the Company's activities, the result of which may be to furnish an advantage to the Company's competitors. Any delay in obtaining or failure to obtain such approvals would adversely affect the marketing of the Company's products and the ability to earn product revenue. Before testing of any agents with potential therapeutic value in healthy human test subjects or patients may begin, stringent government requirements for pre-clinical data must be satisfied. These data, obtained from studies in several animal species, as well as from laboratory studies, are submitted in a Notice of Claimed Investigational Exemption for a New Drug or its equivalent in countries outside the U.S. where clinical studies are to be conducted. If the necessary authorizations are received, the Company then conducts clinical tests of its products on human beings at various unaffiliated medical centers and institutions. Initial trials (Phase 1) are conducted on a small number of volunteers to determine whether the drug is safe for human beings. If the initial trials demonstrate the safety of the product, trials (Phase 2) are then conducted on patients affected with the disease or condition under investigation to establish the proper dose and dosing interval. The findings of these trials are then used to design and implement large-scale controlled trials (Phase 3) to provide statistical proof of effectiveness and adequate evidence of safety to meet FDA and/or foreign approval requirements. The FDA closely monitors the progress of each of the phases of clinical testing and may, at its discretion, re-evaluate, alter, suspend, or terminate the testing based on the data which have been accumulated to that point and its assessment of the risk/benefit ratio to the patient. Estimates of the total time required for completing clinical testing vary between four and ten years. Upon successful completion of clinical testing of a new drug, a company typically submits a New Drug Application ("NDA"), or for biological products such as Natural Alpha Interferon, a Biological License Application ("BLA"), to the FDA summarizing the results and observations of the drug during the clinical trials. Each facility, in which products are produced and packaged, whether operated by the Company or a third party, must meet the FDA's standards for current good manufacturing practices and must also be approved prior to marketing any product produced or packaged in such facility. Any significant change in the production process that may be commercially required, including changes in sources of certain raw materials, or any change in the location of the production facilities will also require FDA approval. To the extent a portion of the manufacturing process for a product is handled by an entity other than the Company, the Company must similarly receive FDA approval for the other entity's participation in the manufacturing process. Abbott formulates and packages ALFERON N Injection. The Company presently has a biologic establishment license for the facilities in which it produces ALFERON N Injection, which includes the facilities in which Abbott formulates and packages ALFERON N Injection. Once the manufacture and sale of a product is approved, various FDA regulations govern the production processes and marketing activities of such product. A post-marketing testing, surveillance, and reporting program may be required to monitor the product's usage and effects. Product approvals may be withdrawn, or other actions may be ordered, if compliance with regulatory standards is not maintained. Each individual lot of Natural Alpha Interferon produced must be tested for compliance with specifications and released for sale by the FDA prior to distribution in the marketplace. Even after initial FDA marketing approval for a product has been granted, further studies may be required to provide additional data on safety or efficacy; to obtain approval for marketing a product as a treatment for specific diseases other than those for which the product was originally approved; to change the dosage levels of a product; to support new safety or efficacy claims for the product; or to support changes in manufacturing methods, facilities, sources of raw materials, or packaging. In many markets, effective commercialization also requires inclusion of the product in national, state, provincial, or institutional formularies or cost reimbursement systems. The impact of new or changed laws or regulations cannot be predicted with any accuracy. The Company uses its own staff of regulatory affairs professionals and outside consultants to enable it to monitor compliance, not only with FDA laws and regulations, but also with state and foreign government laws and regulations. Promotional and educational communications by the Company and its distributors also are regulated by the FDA and are governed by statutory and regulatory restrictions and FDA policies regarding the type and extent of data necessary to support claims that may be made. The Company currently does not have data adequate to satisfy FDA requirements with respect to potential comparative claims between Natural Alpha Interferon and competing recombinant interferon products. For marketing outside the United States, the Company will also be subject to foreign regulatory requirements governing human clinical trials, manufacturing, and marketing approval for drugs and other medical products. The requirements governing the conduct of clinical trials, product licensing, pricing, and reimbursement vary widely from country to country. Under certain circumstances, the Company may be required to obtain FDA authorization to export products for sale in foreign countries. For instance, in most cases, the Company may not export products that have not been approved by the FDA unless it first obtains an export permit from the FDA. However, these FDA export restrictions generally do not apply if the Company's products are exported in conformance with their United States approvals or are manufactured outside the United States. At the present time, the Company does not have any foreign manufacturing facilities. Employees As of May 1, 2003, the Company had 4 employees, 3 of whom work less than full time. All of such employees are providing services in connection with the Asset Sale Transaction. Research and Development During the years ended December 31, 2002, 2001 and 2000, the Company expended approximately $1.5 million, $2.3 million and $1.5 million, respectively, for research and development. Substantially all of these expenditures were for Company-sponsored research and development programs.

The following table sets forth for each period indicated, the high and low sales prices for the Common Stock as reported on the OTC Bulletin Board.

As of April 30, 2003, the Company had 472 stockholders of record. The Company has not paid any dividends on the Common Stock since its inception and does not contemplate paying dividends on the Common Stock in the foreseeable future.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations Since 1981, the Company was engaged in the research and development of pharmaceutical products containing Natural Alpha Interferon. The Company has experienced significant operating losses since its inception. The Company received FDA approval in 1989 to market ALFERON N Injection in the United States for the treatment of certain types of genital warts. Agreement with Hemispherx Biopharma, Inc. ("HEB") On March 11, 2003, the Company executed the Asset Sale Transactions with HEB to sell certain assets of ISI. In the First Asset Sale Agreement, ISI sold all of its inventory related to ALFERON N Injection(R) and granted a three-year license for the production, manufacture, use, marketing and sale of the product in the United States. For these assets, ISI: (i) received 424,528 shares of HEB common stock (the "Common Stock") (these shares, along with other shares described below as having a guaranteed value, are sometimes referred to as the "Guaranteed Shares") which had a Market Value (as defined in the First Asset Sale Agreement) of $675,000 and a guaranteed value of $675,000; (ii) received an additional 62,500 shares of Common Stock without a guaranteed value; and (iii)will receive a royalty equal to 6% of the net sales of the product. ISI will receive a service fee for providing certain transitional services. In addition, HEB will assume ISI payables and certain other obligations related to the Product. This Agreement obligates HEB to register the Common Stock issued to ISI, sets periodic limits on the number of shares ISI may sell and requires HEB to pay ISI an amount equal to the product received by multiplying (i) the number of Guaranteed Shares remaining unsold on March 11, 2005 and (ii) $ 1.59. The remaining Guaranteed Shares will then be returned to HEB. In the Second Asset Sale Agreement, ISI has agreed to sell, subject to certain approvals, to HEB all of its rights to natural alpha interferon, (the "Product") and other assets related to the Product including, but not limited to, real estate and machinery. For these assets, ISI will: (i) receive 424,528 shares of HEB Common Stock which has a Market Value (as defined in the Second Asset Sale Agreement) of $675,000 and a guaranteed value of $675,000; (ii) receive an additional 62,500 shares of HEB Common Stock without a guaranteed value; and (iii)receive a royalty equal to 6% of the net sales of any products containing natural alpha interferon sold by HEB (or a Marketing Partner, as defined in the Second Asset Sale Agreement). In addition, HEB will be required to satisfy three obligations of ISI which aggregate approximately $2,300,000. HEB will be obligated to pay certain ongoing expenses related to ISI's operations prior to the closing of the Second Asset Sale Agreement. The Second Asset Sale Agreement obligates HEB to register the Common Stock to be issued, sets periodic limits on the number of these shares that may be sold and requires HEB to pay ISI an amount equal to the product received by multiplying (i) the number of Guaranteed Shares remaining unsold on the date which is two years after the closing date of the Second Asset Sale Agreement and (ii) $1.59. The remaining Guaranteed Shares will then be returned to HEB. The purchase price for the assets was determined by negotiation between HEB and ISI. The foregoing descriptions of the Asset Sale Transactions, the First Asset Sale Agreement and the Second Asset Sale Agreement are qualified in their entirety by reference to the full text of the First Asset Sale Agreement, the Second Asset Sale Agreement, which are filed as Exhibits 2.1 and 2.2 to the Current Report on Form 8-K, dated March 18, 2003, and incorporated herein by reference. Liquidity and Capital Resources During the year ended December 31, 2002, the Company generated $1,926,466 in revenues from the sale of ALFERON N Injection and received $528,276 from the sale of the Company's New Jersey net operating loss carryovers. In addition, the Company completed a private placement of $500,000 of convertible notes to accredited investors. Each note is convertible into the Company's common stock at a price of $.05 per share (subject to adjustment to 70% of the market price of the Company's common stock under certain circumstances) and bears interest at the rate of 10% per annum. $250,000 of the convertible notes was due January 31, 2003 and the other $250,000 of the convertible notes are due December 31, 2003. For each $100,000 principal amount of notes issued, the investors received warrants to purchase an additional 10.2 million shares of the Company's common stock exercisable at $.01 per share. The transaction is subject to approval by the shareholders of the Company. In the event that shareholder approval is not obtained, the convertible noteholders could exercise their rights and call a default making the convertible notes immediately due and payable. All of the above accounted for substantially all of the Company's funding in 2002. As of June 12, 2003, the Company had an aggregate of approximately $195,000 in cash and cash equivalents. Until utilized, such cash and cash equivalents are being invested principally in short-term interest-bearing investments. At the current time, the Company is focusing its efforts on completing the Asset Sale Transactions and evaluating new opportunities for the Company. Based on the Company's sale to HEB, estimates of revenue, expenses, and the timing of repayment of creditors, management believes that the cash presently available will be sufficient to enable the Company to continue operations until the third quarter of 2003. However, actual results may differ materially from such estimate, and no assurance can be given that additional funding will not be required sooner than anticipated or that such additional funding will be available when needed or on terms acceptable to the Company. Insufficient funds will require the Company to scale back or terminate operations. The independent auditors' report, dated June 10, 2003 on the Company's consolidated financial statements as of and for the years ended December 31, 2002 and 2001 included an explanatory paragraph that states that the Company has experienced a significant loss from operations, has a capital deficiency, and a negative working capital position. These factors raise substantial doubt about its ability to continue as a going concern. On April 9, 2001, the Company exercised its option to acquire a substantial equity interest in Metacine, Inc. Pursuant to the agreement, as amended, the Company received 700,000 shares of Metacine common stock and a five-year warrant to purchase, at a price of $12.48 per share, 282,794 shares of Metacine common stock in exchange for $300,000 in cash, $250,000 of services to be rendered by the Company by June 30, 2002 and 2,000,000 shares of the Company's common stock. The agreement contains certain restrictions on the ability of Metacine to sell the Company's shares and provides for cash payments ("Deficiency Payments") by the Company to Metacine to the extent Metacine has not received, from the sale of the Company's common stock, cumulative net proceeds of $1,850,000 by September 30, 2002 or $400,000 of net proceeds per quarter beginning with the period ending September 30, 2001 and $250,000 for the quarter ending September 30, 2002. In October 2001, the Company made a Deficiency Payment to Metacine in the amount of $400,000 for the quarter ending September 30, 2001. The Company has not, as yet, made the remainder of the Deficiency Payments in the aggregate amount of $1,450,000. The Company is currently discussing various options regarding the balance of the Deficiency Payments with Metacine. In the event that and to the extent that cumulative net proceeds to Metacine from the sale of the Company's common stock exceed $1,850,000, any Deficiency Payments previously made by the Company would be repaid to the Company. The Company has participated in the State of New Jersey's corporation business tax benefit certificate transfer program (the "Program"), which allows certain high technology and biotechnology companies to transfer unused New Jersey net operating loss carryovers to other New Jersey corporation business taxpayers. During 1999, the Company submitted an application to the New Jersey Economic Development Authority (the "EDA") to participate in the Program and the application was approved. The EDA then issued a certificate certifying the Company's eligibility to participate in the Program and the amount of New Jersey net operating loss carryovers the Company has available to transfer. Since New Jersey law provides that net operating losses can be carried over for up to seven years, the Company may be able to transfer its New Jersey net operating losses from the last seven years. The Company estimated that, as of January 1, 1999, it had approximately $85 million of unused New Jersey net operating loss carryovers available for transfer under the Program. The Program requires that a purchaser pay at least 75% of the amount of the surrendered tax benefit. During December 2002, 2001, and 2000, the Company completed the sale of approximately $6.5 million, $12 million, and $19 million of its New Jersey tax loss carryovers and received $0.53 million, $0.97 million, and $1.48 million, which were recorded as a gain on sale of state net operating loss carryovers on the Company's Consolidated Statement of Operations in 2002, 2001, and 2000, respectively. If the Company is eligible, in June 2003, the Company will submit an application to sell an additional approximately $2.0 million of tax benefits (calculated by multiplying the Company's unused New Jersey net operating loss carryovers through December 31, 2000 of approximately $22.6 million by 9%). The actual amount of such tax benefits the Company may sell will depend upon the allocation among qualifying companies of an annual pool established by the State of New Jersey. The allocated pool for fiscal year 2003 and future years is $40 million per year. The Company obtained human white blood cells used in the manufacture of ALFERON N Injection from several sources, including the Red Cross pursuant to a supply agreement dated April 1, 1997 (the "Supply Agreement"). The Company will not need to purchase more human white blood cells until such time as production of crude alpha interferon is resumed. Under the terms of the Supply Agreement, the Company was obligated to purchase a minimum amount of human white blood cells each month through March 1999 (the "Minimum Purchase Commitment"), with an aggregate Minimum Purchase Commitment during the period from April 1998 through March 1999 in excess of $3,000,000. As of November 23, 1998, the Company owed the Red Cross approximately $1.46 million plus interest at the rate of 6% per annum accruing from April 1, 1998 (the "Red Cross Liability") for white blood cells purchased pursuant to the Supply Agreement. In an agreement dated November 23, 1998, the Company agreed to grant the Red Cross a security interest in certain assets to secure the Red Cross Liability and to issue to the Red Cross 300,000 shares of common stock and additional shares at some future date as requested by the Red Cross to satisfy any remaining amount of the Red Cross Liability. The Red Cross agreed that any net proceeds received by it upon sale of such shares would be applied against the Red Cross Liability and that at such time as the Red Cross Liability was paid in full, the Minimum Purchase Commitment would be deleted effective April 1, 1998 and any then existing breaches of the Minimum Purchase Commitment would be waived. In January 1999 the Company granted the Red Cross a security interest (the "Security Interest") in, among other things, the Company's real estate, equipment inventory, receivables, and New Jersey net operating loss carryovers to secure repayment of the Red Cross Liability, and the Red Cross agreed to forbear from exercising its rights under the Supply Agreement, including with respect to collecting the Red Cross Liability, until June 30, 1999 (which was subsequently extended until December 31, 1999). On December 29, 1999, the Company, the Red Cross and GP Strategies entered into an agreement pursuant to which the Red Cross agreed that until September 30, 2000 it would forbear from exercising its rights under (i) the Supply Agreement, including with respect to collecting the Red Cross Liability, and (ii) the Security Interest. In connection with the Asset Sale Transactions, the Company, HEB and the Red Cross entered into a similar agreement pursuant to which the Red Cross agreed to forbear from exercising its rights until May 31, 2003 and the Red Cross agreed to accept HEB common stock with a guaranteed value of $500,000 in full settlement of all of the Company's obligations to the Red Cross. Under the terms of such agreement, if HEB does not make such payment, the Red Cross has the right to sell the Company's real estate. Pursuant to an agreement dated March 25, 1999, GP Strategies loaned the Company $500,000 (the "GP Strategies Debt"). In return, the Company agreed to grant GP Strategies (i) a first mortgage on the Company's real estate, (ii) a two-year option (which has expired) to purchase the Company's real estate, provided that the Company has terminated its operations and the Red Cross Liability has been repaid, and (iii) a two-year right of first refusal (which has expired) in the event the Company desires to sell its real estate. In addition, the Company agreed to issue GP Strategies 500,000 shares of common stock (the "GP Shares") and a five-year warrant (the "GP Warrant") to purchase 500,000 shares of common stock at a price of $1 per share. The common stock and warrants issued to GP Strategies were valued at $500,000 and recorded as a financing cost and amortized over the original period of the GP Strategies Debt in 1999. Pursuant to the agreement, the Company issued a note to GP Strategies representing the GP Strategies Debt, which note was due on September 30, 1999 and bears interest, payable at maturity, at the rate of 6% per annum. In addition, at that time the Company negotiated a subordination agreement with the Red Cross pursuant to which the Red Cross agreed that its lien on the Company's real estate is subordinate to GP Strategies' lien. On March 27, 2000, the Company and GP Strategies entered into an agreement pursuant to which (i) the GP Strategies Debt was extended until June 30, 2001, and (ii) the Management Agreement between the Company and GP Strategies was terminated and all intercompany accounts between the Company and GP Strategies (other than the GP Strategies Debt) in the amount of approximately $130,000 were discharged which was recorded as a credit to capital in excess of par value. On August 23, 2001, the Company and GP Strategies entered into an agreement pursuant to which the GP Strategies Debt was extended to March 15, 2002. During 2001, the Company paid GP Strategies $100,000 to reduce the GP Strategies Debt. In addition, in January 2002, the Company paid GP Strategies $100,000 to further reduce the GP Strategies Debt. In connection with the Asset Sale Transactions, the Company, HEB and GP Strategies entered into a similar agreement pursuant to which GP Strategies agreed to forbear from exercising its rights until May 31, 2003 and GP Strategies agreed to accept HEB common stock with a guaranteed value of $425,000 in full settlement of all of the Company's obligations to GP Strategies. Under the terms of such agreement, if HEB does not make such payment, GP Strategies has the right to sell the Company's real estate. The Company's common stock now trades on the OTC Bulletin Board, which may have a material adverse effect on the ability of the Company to finance its operations and on the liquidity of the common stock. Critical Accounting Policies Inventory reserves - The Company provides inventory reserves based on the anticipated near-term projections of product to be sold or utilized in clinical trials, giving consideration to historical sales levels. These estimates could be materially different from actual usage. Commitments As discussed above, the Company is obligated to make Deficiency Payments to Metacine for which the Company owes an aggregate amount of $1,450,000. The Company also has not rendered $250,000 of services to Metacine. The Company is currently in discussions with Metacine with respect to a full settlement of the Company's obligations to Metacine. Also as discussed above, the Company's note payable to GP Strategies of approximately $414,000 was due March 15, 2002 and has not yet been paid. In connection with the Asset Sale Transactions, the Company, HEB and GP Strategies entered into a similar agreement pursuant to which GP Strategies agreed to forbear from exercising its rights until May 31, 2003 and GP Strategies agreed to accept HEB common stock with a guaranteed value of $425,000 in full settlement of all of the Company's obligations to GP Strategies. As consideration for the transfer to the Company of certain licenses, rights and assets upon the formation of the Company by GP Strategies, the Company agreed to pay GP Strategies royalties of $1,000,000, but such payments will be made only with respect to those years in which the Company has income before income taxes, and will be limited to 25% of such income. Through December 31, 2002, the Company has not generated income before taxes and therefore has not accrued or paid royalties to GP Strategies. Major Research and Development Projects Cancer During the year ended December 31, 2002, the Company incurred $101,565 in connection with its collaboration with the Mayo Foundation for Medical Education and Research pursuant to which the Company is funding a clinical trial entitled "Identification of an Immunostimulatory Dose of Natural Interferon (Phase A) and Its Impact on Clinical Outcome (Phase B) in Patients with Melanoma. The Company estimates that the time to complete this trial will be at least two years. However, because of the need to recruit patients who meet certain limited criteria to complete the trial, it is very difficult to accurately estimate the date the trial will be completed. Under the terms of the Company's agreement with Mayo, the cost to complete this clinical trial is approximately $200,000. Under the terms of the Company's agreement with Hemispherx (see "Business - General Development of the Business - Agreement with Hemispherx Biopharma, Inc.") the Company's right to continue this agreement and the obligation owed to Mayo was transferred to Hemispherx. Multiple Sclerosis During the year ended December 31, 2001, the Company incurred approximately $91,594 funding a study which entailed a retrospective review of multiple brain magnetic resonance imaging (MRI) scans to assess MS brain lesion burden. The study compared the scans of 40 MS patients treated with interferon alfa-n3 (ALFERON N Injection) as well as 40 MS patients treated with interferon beta-1b (Betaseron(R)), both before therapy and at least six months after initiation of therapy. A control group of 39 untreated MS patient scans were also evaluated with an initial MRI scan at baseline and a second MRI obtained at least six months after the baseline examination. On the 238 scans evaluated (119 patients) only lesions of larger than 5 mm3 were measured to avoid inclusion of potential non-MS lesions and assure accuracy of measurement. All scans were reviewed by consensus of two experienced neuroradiologists who were blinded to all identifiers, including name, date, order of scans, and clinical status of the patient. The study data showed a reduction in the volume of T2-weighted MS brain lesions in both the interferon alfa-n3 treated group (-10%) and the interferon beta-1b treated group (-7%), as compared to increased lesion volume in the untreated control group (+12%). Changes in disability scores amongst the groups were also retrospectively reviewed, based on the extended disability status scale (EDSS). Only patients with EDSS scores recorded both at baseline and after at least 12 months were evaluated, which included 38 interferon alfa-n3 treated patients, 31 interferon beta-1b treated patients, and 33 untreated patients. The results showed the mean absolute change in EDSS scores from baseline to be -1.07 for interferon alfa-n3 treated patients and -0.16 for interferon beta-1b treated patients after 12 months, as compared to +0.80 for untreated patients (negative changes reflect decreased disability scores, positive change reflects increased disability scores). The scale of EDSS scores ranges from 0 for a normal neurological examination to a score of 10 for death due to MS. Under the terms of the Company's agreement with Hemispherx (see "Business - General Development of the Business - Agreement with Hemispherx Biopharma, Inc.") the Company's right to continue work utilizing ALFERON N Injection for the treatment of multiple sclerosis was licensed to Hemispherx. Results of Operations Year Ended December 31, 2002 Versus Year Ended December 31, 2001 For the year ended December 31, 2002 (the "2002 Period") and 2001 (the "2001 Period"), the Company had revenues from the sale of ALFERON N Injection of $1,926,466 and $1,498,603, respectively. During the first quarter of 2002, the Company notified its customers of a price increase for ALFERON N Injection. As a result, several wholesalers purchased above-normal quantities of ALFERON N Injection ahead of the price increase. In addition, during the third quarter of 2002, the Company offered price concessions to its largest customers in an attempt to raise cash from the sale of ALFERON N Injection, which resulted in greater than normal sales in the 2002 period. In the 2002 Period, the Company sold, through its distributor, to wholesalers and other customers in the United States 15,012 vials of ALFERON N Injection, compared to 11,296 vials sold by the Company during the 2001 Period. In addition, foreign sales of ALFERON N Injection were zero vials and 61 vials for the 2002 and 2001 Periods, respectively. Cost of goods sold and excess/idle production costs totaled $1,482,006 and $1,485,962 for the 2002 and 2001 Periods, respectively. Excess/idle production costs in the 2002 and 2001 Periods represented fixed production costs, which were incurred after production of ALFERON N Injection was discontinued in April 1998. Excess/idle production costs were slightly lower during the 2002 Period as compared to the 2001 Period. Research and development expenses during the 2002 Period of $1,514,286 decreased by $772,014 from $2,286,300 for the 2001 Period, due to decreases in both external research payments and internal research costs. General and administrative expenses for the 2002 Period were $1,818,194 as compared to $2,646,734 for the 2001 Period. The decrease of $828,540 was principally due to decreases in payroll, consulting and public relations expenses. The Company recorded $2,341,418 as acquisition of in-process research and development expenses related to its investment in Metacine for the 2001 Period as Metacine's primary asset is technology which has not reached technological feasibility and has no alternative uses. See Note 7 of Notes to Consolidated Financial Statements. Interest income for the 2002 Period was $7,122 as compared to $108,351 for the 2001 Period. The decrease of $101,229 was due to less funds available for investment in the 2002 Period. Interest expense for the 2002 Period was $385,775 as compared to $91,469 for the 2001 Period. The increase of $294,306 was primarily due to the interest, including amortization of debt discount, on the convertible notes payable. Equity in loss of Metacine for the 2001 Period was $158,582 and represents the Company's equity in loss of Metacine for the period from April 9, 2001 to December 31, 2001. During 2002 and 2001, the Company completed the sale of a portion of its New Jersey tax net operating loss carryforwards and recorded a gain on such sale amounting to $528,276 and $968,553, which is recorded as an income tax benefit in the 2002 and 2001 Periods, respectively. As a result of the foregoing, the Company incurred net losses of $2,738,397 and $6,434,958 for the 2002 and 2001 Periods, respectively. Year Ended December 31, 2001 versus Year Ended December 31, 2000 For the year ended December 31, 2001 (the "2001 Period") and 2000 (the "2000 Period"), the Company had revenues from the sale of ALFERON N Injection of $1,498,603 and $1,067,471, respectively. In 1999, the Company offered price concessions to its largest customers in an attempt to raise cash from the sale of ALFERON N Injection, which resulted in lower than normal sales in the 2000 Period. This was due to the fact that such customers were selling out of their inventory of ALFERON N Injection (rather than purchasing ALFERON N Injection from the Company). In the 2001 Period, the Company sold, through its distributor, to wholesalers and other customers in the United States 11,296 vials of ALFERON N Injection, compared to 7,946 vials sold by the Company during the 2000 Period. In addition, foreign sales of ALFERON N Injection were 61 vials and 132 vials for the 2001 and 2000 Periods, respectively. Cost of goods sold and excess/idle production costs totaled $1,485,962 and $1,455,929 for the 2001 Period and 2000 Period, respectively. Excess/idle production costs in the 2001 and 2000 Periods represented fixed production costs, which were incurred after production of ALFERON N Injection was discontinued in April 1998. Excess/idle production costs were slightly lower during the 2001 Period as compared to the 2000 Period. Research and development expenses during the 2001 Period of $2,286,300 increased by $752,976 from $1,533,324 for the 2000 Period, principally because during the second quarter of 2000, the Company settled amounts owed on various research related liabilities at a savings to the Company of approximately $457,000. Such amount was credited against research and development expenses. The Company also incurred increases in payroll and research costs during the 2001 Period, as compared to the 2000 Period. General and administrative expenses for the 2001 Period were $2,646,734 as compared to $2,306,146 for the 2000 Period. The increase of $340,588 was principally due to increases in payroll and other operating expenses. The Company recorded $2,341,418 as acquisition of in-process research and development expense related to its investment in Metacine for the 2001 Period as Metacine's primary asset is technology which has not reached technological feasibility and has no alternative uses. The in-process research and development expenses relate to research utilizing dendritic cells for the treatment of various diseases. Interest income for the 2001 Period and 2000 Period was $108,351 and $161,835, respectively. The decrease of $53,484 was due to less funds available for investment in the 2001 Period. Interest expense for the 2001 Period and 2000 Period was $91,469 and $87,873, respectively, and represents interest expense accrued on the Red Cross Liability and GP Strategies Debt. Equity in loss of Metacine for the 2001 Period was $158,582 and represents the Company's equity in loss of Metacine for the period from April 9, 2001 to December 31, 2001. During 2001 and 2000, the Company completed the sale of a portion of its New Jersey tax net operating loss carryforwards and recorded a gain on such sale amounting to $968,553 and $1,483,861, which is recorded as an income tax benefit in the 2001 and 2000 Periods, respectively. As a result of the foregoing, the Company incurred net losses of $6,434,958 and $2,668,663 for the 2001 Period and 2000 Period, respectively. Recently Issued Accounting Standards In June 2001, the FASB issued SFAS No. 141, Business Combinations, ("SFAS No. 141") and SFAS No. 142, Goodwill and Other Intangible Assets ("SFAS No. 142"). SFAS No. 141 requires that the purchase method of accounting be used for all business combinations. SFAS No. 141 specifies criteria that intangible assets acquired in a business combination must meet to be recognized and reported separately from goodwill. SFAS No. 142 requires that goodwill and intangible assets with indefinite useful lives no longer be amortized, but instead tested for impairment at least annually in accordance with the provisions of SFAS No. 142. SFAS No. 142 also requires that intangible assets with estimable useful lives be amortized over their respective estimated useful lives to their estimated residual values, and reviewed for impairment in accordance with SFAS No. 121 and subsequently, SFAS No. 144 after its adoption. The Company adopted the provisions of SFAS No. 141 as of July 1, 2001, and SFAS No. 142 as of January 1, 2002. Upon adoption of SFAS No. 142, the Company was required to reassess the useful lives and residual values of all intangible assets acquired, and make any necessary amortization period adjustments by the end of the first interim period after adoption. If an intangible asset was identified as having an indefinite useful life, the Company would be required to test the intangible asset for impairment in accordance with the provisions of SFAS No. 142 within the first interim period. Impairment is measured as the excess of carrying value over the fair value of an intangible asset with an indefinite life. Any impairment loss would be measured as of the date of adoption and recognized as the cumulative effect of a change in accounting principle in the first interim period. As of the date of adoption of SFAS No. 142, the Company does not have any goodwill and has unamortized identifiable intangible assets of approximately $160,000, all of which is subject to the transition provisions of SFAS No. 142. In August 2001, the FASB issued SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets ("SFAS No. 144"). SFAS No. 144 addresses financial accounting and reporting for the impairment or disposal of long-lived assets. This Statement requires that long-lived assets be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. SFAS No. 144 requires companies to separately report discontinued operations and extends that reporting to a component of an entity that either has been disposed of (by sale, abandonment, or in a distribution to owners) or is classified as held for sale. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. The Company adopted SFAS No. 144 on January 1, 2002. In April 2002, the FASB issued SFAS No. 145, "Rescission of FAS Statements 4, 44 and 64, Amendment of FAS Statement 13 and Technical Corrections." SFAS No. 145 eliminates Statement 4 (and Statement 64, as it amends Statement 4), which required gains and losses from extinguishment of debt to be aggregated and, if material, classified as an extraordinary item, and thus, also the exception to applying Opinion 30 is eliminated as well. This statement is effective for fiscal years beginning after May 2002 for the provisions related to the rescission of Statements 4 and 64 and for all transactions entered into beginning May 2002 for the provision related to the amendment of Statement 13. The Company does not expect that the adoption of SFAS No. 145 will have a material impact on its results of operations or financial position. In June 2002, the FASB issued SFAS No. 146, "Accounting for Costs associated with Exit or Disposal Activities." SFAS No. 146 requires recording costs associated with exit or disposal activities at their fair values when a liability has been incurred. Under previous guidance, certain exit costs were accrued upon management's commitment to an exit plan. The Company is required to adopt SFAS No. 146 on January 1, 2003. The Company does not expect the adoption of SFAS No. 146 will have a material impact on its results of operations or financial position. In December 2002, the FASB issued SFAS No. 148, "Accounting for Stock-Based Compensation - Transition and Disclosure," an amendment to SFAS No. 123, "Accounting for Stock-Based Compensation." Provisions of this statement provide two additional alternative transition methods: modified prospective method and retroactive restatement method, for an entity that voluntary changes to the fair value based method of accounting for stock-based employee compensation. The statement eliminates the use of the original SFAS No. 123 prospective method of transition alternative for those entities that change to the fair value based method in fiscal years beginning after December 15, 2003. It also amends the disclosure provisions of SFAS No. 123 to require prominent annual disclosure about the effects on reported net income in the Summary of Significant Accounting Policies and also requires disclosure about these effects in interim financial statements. These provisions are effective for financial statements for fiscal years ending after December 15, 2002. Accordingly, the Company adopted the applicable disclosure requirements of this statement for year-end reporting. The transition provisions of this statement apply upon the adoption of the SFAS No. 123 fair value based method. The Company did not change its method of accounting for employee stock-based compensation from the intrinsic method to the fair value based alternative. Forward-Looking Statements This report contains certain forward-looking statements reflecting management's current views with respect to future events and financial performance. These forward-looking statements are subject to certain risks and uncertainties that could cause actual results to differ materially from those in the forward-looking statements, including, but not limited to, the risk that the Company will run out of cash; uncertainty of obtaining additional funding for the Company; uncertainty of obtaining United States regulatory approvals for the additional uses under development for the Company's FDA-approved product and foreign regulatory approvals if sought and if such approvals are obtained, uncertainty of the successful commercial development of such product; substantial competition from companies with substantially greater resources than the Company in the Company's present and potential businesses; no guaranteed source of required materials for the Company's product; dependence on certain contractors to manufacture or distribute the Company's product; potential adverse side effects from the use of the Company's product; potential patent infringement claims against the Company; possible inability of the Company to protect its technology; limited production experience of the Company, risk of product liability; and risk of loss of key management personnel, all of which are difficult to predict and many of which are beyond the control of the Company.

INDEPENDENT AUDITOR'S REPORT The Board of Directors and Stockholders Interferon Sciences, Inc. We have audited the accompanying consolidated balance sheets of Interferon Sciences, Inc. and subsidiary as of December 31, 2002 and 2001 and the related consolidated statements of operations, changes in stockholders' equity capital deficiency and cash flows for each of the years in the three-year period ended December 31, 2002. These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audit in accordance with auditing standards generally accepted in the United States of America. These standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Interferon Sciences, Inc. and subsidiary as of December 31, 2002 and 2001 and the consolidated results of their operations and their consolidated cash flows for each of the years in the three-year period ended December 31, 2002, in conformity with accounting principles generally accepted in the United States of America. The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 3 to the financial statements, the Company has experienced a significant net losses in each of the years in the three-year period ended December 31, 2002 and at December 31, 2002, has a capital deficiency and a negative working capital position. These factors raise substantial doubt about its ability to continue as a going concern. Management's plans in regard to these matters are also described in Note 3. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. In connection with our audit of the financial statements referred to above, we audited Schedule II - Valuation and Qualifying Accounts for 2002. In our opinion, this schedule, when considered in relation to the financial statements taken as a whole, presents fairly, in all material respects, the information stated therein. Eisner LLP New York, New York June 10, 2003

INTERFERON SCIENCES, INC. AND SUBSIDIARY NOTES TO CONSOLIDATED FINANCIAL STATEMENTS Note 1. Organization and Business Interferon Sciences, Inc. (the "Company") is a biopharmaceutical company that operates in a single segment and is engaged in the study, manufacture, and sale of pharmaceutical products based on its highly purified, multispecies, natural source alpha interferon ("Natural Alpha Interferon"). The Company's ALFERON(R) N Injection (Interferon Alfa-n3) product has been approved by the United States Food and Drug Administration ("FDA") for the treatment of certain types of genital warts and the Company has studied its potential use in the treatment of HIV, hepatitis C, and other indications. Alferon N Injection is sold principally in the United States, however, a portion is sold in foreign countries. For the years ended December 31, 2002, 2001 and 2000, domestic sales totaled $1,926,466, $1,488,897, and $1,046,470, respectively, and foreign sales totaled zero, $9,706, and $21,001, respectively. All identifiable assets are located in the United States. Subsequent to December 31, 2002, the Company sold its inventory and granted a license to its products to Hemispherx Biopharma, Inc. See Note 20. Integrated Commercialization Solutions, Inc. ("ICS"), a subsidiary of AmerisourceBergen Corporation, is the sole United States distributor of ALFERON N Injection. ICS distributes ALFERON N Injection to a limited number of wholesalers throughout the United States. Note 2. Summary of Significant Accounting Policies Principles of consolidation -- The consolidated financial statements include the operations of the Company and Interferon Sciences Development Corporation ("ISD"), its wholly owned subsidiary. All significant intercompany transactions and balances have been eliminated. The transactions and balances of Metacine, Inc. are being accounted for under the equity method (see Note 7). The losses of Metacine from April 9, 2001, the date of the Company's acquisition of an 82% equity interest in Metacine through December 31, 2001, have been reflected in the accompanying statement of operations as equity in loss of Metacine to the extent of the Company's carrying value of the investment in Metacine. At December 31, 2001, the carrying value was written down to $-0-. Cash and cash equivalents -- The Company considers all highly liquid instruments with maturities of three months or less from purchase date to be cash equivalents. Property, plant and equipment -- Property, plant and equipment are carried at cost. Major additions and improvements are capitalized while maintenance and repairs, which do not extend the lives of the assets, are expensed. Depreciation -- The Company provides for depreciation and amortization of plant and equipment following the straight-line method over the estimated useful lives of such assets as follows: Class of Assets Estimated Useful Lives Buildings and Improvements 15 to 30 years Equipment 5 to 10 years Depreciation expense for the years ended December 31, 2002, 2001 and 2000 was $396,922, $478,082 and $472,101, respectively. Patent costs -- The Company capitalizes costs to obtain patents and licenses. Patent costs are amortized over 17 years on a straight-line basis. To the extent a patent is determined to be worthless, the related net capitalized cost is immediately expensed. Revenue recognition -- Title passes to the customer at the shipping point and revenue is therefore recognized when the product is shipped. The Company's product is also tested by its quality control department prior to shipment. The Company has no other obligation associated with its products once shipment has occurred. Research and Development Costs - Research and development are expensed when incurred. The types of costs included in research and development are: salaries, supplies, clinical costs, facility costs and depreciation. All of these expenditures were for Company sponsored research and development programs. During 2000, the Company settled amounts owed by the Company on various research related liabilities at a savings to the Company of approximately $457,000. The amount was credited against research and development expenses in 2000. Inventories -- Inventories, consisting of raw materials, work in process and finished goods, are stated at the lower of cost or market on a FIFO basis. Inventory in excess of the Company's estimated usage requirements is written down to its estimated net realizable value. Inherent in the estimates of net realizable value is management estimates related to the Company's future manufacturing schedules, customer demand, possible alternative uses and ultimate realization of potentially excess inventory. Long-Lived Assets -- The Company reviews long-lived assets and certain identifiable intangibles for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net cash flows expected to be generated by the assets. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the estimated fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or estimated fair value less costs to sell. Stock option plan - The Company accounts for its stock-based compensation to employees and members of the Board of Directors in accordance with the provisions of Accounting Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued to Employees," and related interpretations. As such, compensation is recorded on the date of issuance or grant as the excess of the current market value of the underlying stock over the purchase or exercise price. Any deferred compensation is amortized over the respective vesting periods of the equity instruments, if any. The Company has adopted the disclosure provisions of Statement of Financial Accounting Standards No. 123 ("SFAS No. 123"), "Accounting for Stock-Based Compensation," and Statement of Financial Accounting Standards No. 148, "Accounting for Stock-Based Compensation - Transition and Disclosure," which was released in December 2002 as an amendment of SFAS 123. The following table illustrates the effect on net loss and loss per share if the fair value based method had been applied to all awards.

During 2002 and 2001, the Company did not grant any stock options. The per share weighted-average fair value of stock options granted during 2000 was $.88 on the date of grant using the Black Scholes option-pricing model with the following weighted-average assumptions: expected dividend yield of 0.0%, risk-free interest rate of 6.1%, expected volatility of 142.4% and an expected life of 3.0 years. Loss per share -- Basic loss per share (EPS) are based upon the weighted average number of common shares outstanding during the period. Diluted EPS are based upon the weighted average number of common shares outstanding during the period assuming the issuance of common shares for all dilutive potential common shares outstanding. At December 31, 2002, 2001 and 2000, the Company's options and warrants outstanding are anti-dilutive and therefore basic and diluted EPS are the same. Use of Estimates in the Preparation of Financial Statements - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Income taxes - Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and for operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the results of operations in the period that includes the enactment date. At December 31, 2002 and 2001, the Company has recorded a full valuation allowance for the net deferred tax asset. Recently Issued Accounting Standards In June 2001, the FASB issued SFAS No. 141, Business Combinations, ("SFAS No. 141") and SFAS No. 142, Goodwill and Other Intangible Assets ("SFAS No. 142"). SFAS No. 141 requires that the purchase method of accounting be used for all business combinations. SFAS No. 141 specifies criteria that intangible assets acquired in a business combination must meet to be recognized and reported separately from goodwill. SFAS No. 142 requires that goodwill and intangible assets with indefinite useful lives no longer be amortized, but instead tested for impairment at least annually in accordance with the provisions of SFAS No. 142. SFAS No. 142 also requires that intangible assets with estimable useful lives be amortized over their respective estimated useful lives to their estimated residual values, and reviewed for impairment in accordance with SFAS No. 121 and subsequently, SFAS No. 144 after its adoption. The Company adopted the provisions of SFAS No. 141 as of July 1, 2001, and SFAS No. 142 as of January 1, 2002. Upon adoption of SFAS No. 142, the Company was required to reassess the useful lives and residual values of all intangible assets acquired, and make any necessary amortization period adjustments by the end of the first interim period after adoption. If an intangible asset was identified as having an indefinite useful life, the Company would be required to test the intangible asset for impairment in accordance with the provisions of SFAS No. 142 within the first interim period. Impairment is measured as the excess of carrying value over the fair value of an intangible asset with an indefinite life. Any impairment loss would be measured as of the date of adoption and recognized as the cumulative effect of a change in accounting principle in the first interim period. As of the date of adoption of SFAS No. 142, the Company does not have any goodwill and has unamortized identifiable intangible assets of approximately $160,000, all of which is subject to the transition provisions of SFAS No. 142. In August 2001, the FASB issued SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets ("SFAS No. 144"). SFAS No. 144 addresses financial accounting and reporting for the impairment or disposal of long-lived assets. This Statement requires that long-lived assets be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. SFAS No. 144 requires companies to separately report discontinued operations and extends that reporting to a component of an entity that either has been disposed of (by sale, abandonment, or in a distribution to owners) or is classified as held for sale. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. The Company adopted SFAS No. 144 on January 1, 2002. In April 2002, the FASB issued SFAS No. 145, "Rescission of FAS Statements 4, 44 and 64, Amendment of FAS Statement 13 and Technical Corrections." SFAS No. 145 eliminates Statement 4 (and Statement 64, as it amends Statement 4), which required gains and losses from extinguishment of debt to be aggregated and, if material, classified as an extraordinary item, and thus, also the exception to applying Opinion 30 is eliminated as well. This statement is effective for fiscal years beginning after May 2002 for the provisions related to the rescission of Statements 4 and 64 and for all transactions entered into beginning May 2002 for the provision related to the amendment of Statement 13. The Company does not expect that the adoption of SFAS No. 145 will have a material impact on its results of operations or financial position. In June 2002, the FASB issued SFAS No. 146, "Accounting for Costs associated with Exit or Disposal Activities." SFAS No. 146 requires recording costs associated with exit or disposal activities at their fair values when a liability has been incurred. Under previous guidance, certain exit costs were accrued upon management's commitment to an exit plan. The Company is required to adopt SFAS No. 146 on January 1, 2003. The Company does not expect the adoption of SFAS No. 146 will have a material impact on its results of operations or financial position. In December 2002, the FASB issued SFAS No. 148, "Accounting for Stock-Based Compensation - Transition and Disclosure," an amendment to SFAS No. 123, "Accounting for Stock-Based Compensation." Provisions of this statement provide two additional alternative transition methods: modified prospective method and retroactive restatement method, for an entity that voluntary changes to the fair value based method of accounting for stock-based employee compensation. The statement eliminates the use of the original SFAS No. 123 prospective method of transition alternative for those entities that change to the fair value based method in fiscal years beginning after December 15, 2003. It also amends the disclosure provisions of SFAS No. 123 to require prominent annual disclosure about the effects on reported net income in the Summary of Significant Accounting Policies and also requires disclosure about these effects in interim financial statements. These provisions are effective for financial statements for fiscal years ending after December 15, 2002. Accordingly, the Company adopted the applicable disclosure requirements of this statement for year-end reporting. The transition provisions of this statement apply upon the adoption of the SFAS No. 123 fair value based method. The Company did not change its method of accounting for employee stock-based compensation from the intrinsic method to the fair value based alternative. Note 3. Operations The Company has experienced significant operating losses since its inception in 1980. As of December 31, 2002, the Company had an accumulated deficit of approximately $140 million. For the years ended December 31, 2002, 2001 and 2000, the Company had losses from operations of approximately $2.9 million, $7.3 million, and $4.2 million, respectively. Also, the Company has limited liquid resources. These factors raise substantial doubt about the Company's ability to continue as a going concern. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Although the Company received FDA approval in 1989 to market ALFERON N Injection in the United States for the treatment of certain genital warts, the Company has had limited success in generating revenue from the sale of ALFERON N Injection to date. During the year ended December 31, 2002, the Company generated $1,926,466 in revenue from the sale of ALFERON N Injection and received $528,276 from the sale of the Company's New Jersey net operating tax loss carryovers. In addition, the Company completed a private placement of $500,000 of convertible notes to accredited investors. At December 31, 2002, the Company had approximately $379,000 of cash and cash equivalents, with which to support future operating activities and to satisfy its financial obligations as they become payable. On March 11, 2003, the Company sold all its inventory related to its ALFERON N Injection product and granted a three-year license to sell the product to Hemispherx Biopharma, Inc. ("HEB"). In exchange for the inventory and license, the Company received HEB common stock with a guaranteed value of $675,000, an additional 62,500 shares of HEB common stock without a guaranteed value, and a royalty equal to 6% of the net sales of ALFERON N Injection. The HEB common stock will be subject to selling restrictions. In addition, HEB assumed approximately $400,000 of the Company's payables and various other commitments. The Company and HEB also entered into another agreement pursuant to which the Company will sell to HEB, subject to regulatory approval, the Company's real estate property, plant, equipment, furniture and fixtures, rights to ALFERON N Injection and all of its patents, trademarks and other intellectual property related to its natural alpha interferon business. In exchange, the Company will receive $675,000 of HEB common stock with a guaranteed value, an additional 62,500 shares of HEB common stock without a guaranteed value and a royalty equal to 6% of the net sales of all products sold containing natural alpha interferon. HEB will assume approximately $2.3 million of the Company's indebtedness that currently encumbers its assets. In addition, HEB will fund the operating costs of the Company's facility pending the completion of this transaction. In the event the Company does not obtain regulatory approval prior to September 12, 2003, either the Company or HEB may terminate the agreement and not complete the transaction. Based on the Company's sale to HEB, estimates of revenue, expenses, and the timing of repayment of creditors, management believes that the Company has sufficient resources to enable the Company to continue operations until the third quarter of 2003. However, actual results, may differ materially from such estimate, and no assurance can be given that additional funding will not be required sooner than anticipated or that such additional funding, whether from financial markets or from other sources, will be available when needed or on terms acceptable to the Company. Insufficient funds will require the Company to terminate operations. Note 4. Restatement At December 31, 1999, the balance of the inventory reserves has been increased to eliminate the effect of the $766,000 reversal of inventory previously written down. This retroactive adjustment results in increasing the Accumulated Deficit at December 31, 1999 by $766,000 and decreasing inventory and total assets by the same amount. In addition, a restatement was required to correct cost of sales and equity in loss of Metacine. The Net Loss and loss per share for the years ended December 31, 2000 and 2001 have also been similarly revised as follows:

Note 5. Agreements with Hoffmann-LaRoche F. Hoffmann-La Roche Ltd. and Hoffmann-LaRoche, Inc. (collectively, "Hoffmann") have been issued patents covering human alpha interferon in many countries throughout the world. In 1995, the Company obtained a non-exclusive perpetual license from Hoffmann (the "Hoffmann Agreement") that grants the Company the worldwide rights to make, use, and sell, without a potential patent infringement claim from Hoffmann, any formulation of Natural Alpha Interferon. The Hoffmann Agreement permits the Company to grant marketing rights with respect to Natural Alpha Interferon products to third parties, except that the Company cannot grant marketing rights with respect to injectable products in any country in which Hoffmann has patent rights covered by the Hoffmann Agreement (the "Hoffmann Territory") to any third party not listed on a schedule of approximately 50 potential marketing partners without the consent of Hoffmann, which consent cannot be unreasonably withheld. Under the terms of the Hoffmann Agreement, the Company is obligated to pay Hoffmann an aggregate royalty on net sales (as defined) of Natural Alpha Interferon products by the Company in an amount equal to (i) 8% of net sales in the Hoffmann Territory, and 2% of net sales outside the Hoffmann Territory of products manufactured in the Hoffmann Territory, up to $75,000,000 of net sales in any calendar year and (ii) 9.5% of net sales in the Hoffmann Territory, and 2% of net sales outside the Hoffmann Territory of products manufactured in the Hoffmann Territory, in excess of $75,000,000 of net sales in any calendar year, provided that the total royalty payable in any calendar year shall not exceed $8,000,000. For the years ended December 31, 2002, 2001 and 2000, the Company recorded approximately $31,000, $60,000, and $42,000, in royalty expenses to Hoffmann, respectively. The Hoffmann Agreement can be terminated by the Company on 30 days notice with respect to the United States patent, any individual foreign patent, or all patents owned by Hoffmann. If the Hoffmann Agreement is terminated with respect to the patents owned by Hoffmann in a specified country, such country is no longer included in the Hoffmann Territory. Accordingly, the Company would not be permitted to market any formulation of alpha interferon in such country. Note 6. Research and Development Agreement with Interferon Sciences Research Partners, Ltd. In 1984, the Company organized ISD to act as the sole general partner of Interferon Sciences Research Partners, Ltd., a New Jersey limited partnership (the "Partnership"). The Company and the Partnership entered into a development contract whereby the Company received substantially all of the net proceeds ($4,414,475) of the Partnership's public offering of limited partnership interests. The Company used the proceeds to perform research, development and clinical testing on behalf of the Partnership for the development of ALFERON Gel containing recombinant interferon. In connection with the formation of the Partnership, ISD agreed to make additional cash contributions for purposes of continuing development of ALFERON Gel if the Partnership exhausted its funds prior to development of such product. ISD is wholly dependent upon the Company for capital to fund such commitment. The Partnership exhausted its funds during 1986, and the Company contributed a total of $1,997,000 during the period from 1986 to 1990, for the continued development of ALFERON Gel. In 1987, the Company filed a Product License Application with the FDA for approval to market ALFERON Gel. In February 1990, the FDA indicated that additional process development and clinical trials would be necessary prior to approval of ALFERON Gel. The Company believed, at that time, that the costs to complete the required process development and clinical trials would be substantial, and there could be no assurance that the clinical trials would be successful. As a result of the above events, in 1992, the Company withdrew its FDA Product License Application for ALFERON Gel containing recombinant interferon. In place of single species recombinant interferon, previously ALFERON Gel's active ingredient, the Company commenced, in 1992, further development of ALFERON Gel using the Company's natural source multi-species alpha interferon ("ALFERON N Gel"). However, at the present time, the Company is not actively pursuing development of ALFERON N Gel and the Company does not have an obligation to provide additional funding to the Partnership. Assuming successful development and commercial exploitation of ALFERON N Gel, which to date has not occurred, the Company may be obligated to pay the Partnership royalties equal to 4% of the Company's net sales of ALFERON N Gel and 15% of revenues received from sublicensing ALFERON N Gel. Note 7. Agreement with Metacine, Inc. On July 28, 2000, the Company acquired for $100,000 an option to purchase certain securities of Metacine, Inc. ("Metacine"), a company engaged in research using dendritic cell technology, on the terms set forth below. On April 9, 2001, the Company exercised its option to acquire an 82% equity interest in Metacine. Pursuant to the agreement, as amended, the Company received 700,000 shares of Metacine common stock and a five-year warrant to purchase, at a price of $12.48 per share, 282,794 shares of Metacine common stock in exchange for $300,000 in cash, an obligation to pay Metacine $ 1,850,000 and $250,000 of services to be rendered by the Company by June 30, 2002. In addition, the Company issued Metacine 2,000,000 shares of the Company's common stock. The agreement contains certain restrictions on the ability of Metacine to sell the Company's shares and provides for the Company to make cash payments ("Deficiency Payments") to Metacine to the extent Metacine has not received from the sale of the Company's common stock, cumulative net proceeds of $1,850,000 by September 30, 2002 or $400,000 of net proceeds per quarter beginning with the period ending September 30, 2001 and $250,000 for the quarter ending September 30, 2002. On October 4, 2001, the Company made a Deficiency Payment to Metacine in the amount of $400,000 for the quarter ending September 30, 2001. The Company has not made the remainder of the Deficiency Payments in the aggregate amount of $1,450,000. If Metacine sells all of the 2,000,000 shares received and the cumulative proceeds from the sales and any Deficiency Payments are less than $1,850,000, the Company may issue to Metacine additional shares of common stock at the Company's full discretion. These additional shares would be treated in the same manner as the original 2,000,000 shares. In the event that cumulative net proceeds to Metacine from the sale of the Company's common stock exceed $1,850,000, any Deficiency Payments previously made by the Company ($400,000 through December 31, 2002) would be repaid to the Company to the extent these proceeds exceed $1,850,000. All additional proceeds beyond the $1,850,000 and repayment of Deficiency Payments, if any, would be for the benefit of Metacine. The Company was required to put in escrow 100,000 Metacine shares to secure its obligations to render $250,000 of services to Metacine and 462,500 Metacine shares to secure its potential obligations to make Deficiency Payments. Since the Company has not made $1,450,000 in Deficiency Payments and has not rendered $250,000 of services to Metcine, Metacine could request 462,500 Metacine shares currently held in escrow to satisfy the Company's past due obligations. Although the Company is the majority owner of Metacine, the Company must, on many matters, vote its shares of Metacine common stock in the same proportion as votes cast by the minority stockholders of Metacine, except for certain matters with respect for which the Company has protective rights. In accordance with EITF Issue No. 96-16, Investor's Accounting for an Investee When the Investor has a Majority of the Voting Interest but the Minority Shareholder or Shareholders have Certain Approval or Veto Rights, the minority holders have substantive participating rights which include controlling the selection, termination and setting of compensation for Metacine management who are responsible for implementing policies and procedures, making operating and capital decisions (including establishing budgets) for Metacine and most other ordinary operating matters, and therefore, the Company does not control Metacine. In addition, the Company only has one representative on a board of directors consisting of three directors. Accordingly, the acquisition is being accounted for under the equity method. Of the $2.5 million consideration paid for Metacine, $2,341,418 was recorded as a charge for the acquisition of in-process research and development ("IPR&D") in 2001. The charge was recorded as the acquisition of IPR&D as Metacine's primary asset is technology that has not reached technological feasibility and has no alternative uses. The in-process research and development expenses relate to a patent portfolio consisting of six issued patents, eight pending patents and four invention disclosures related to the use of dendritic cells for the treatment of various diseases. While the patent portfolio, when viewed as a whole, represented a new approach to the treatment of various diseases utilizing cell therapy, the six issued patents had no independent commercial value. While the Company did not engage the services of an independent appraiser to assess the fair value of the purchased in process research and development, it considered the following factors: (i) any product or process utilizing dendritic cells as a treatment for any disease would regulated by the FDA and therefore would require extensive clinical testing prior to the time any revenue would be generate from the sale of a product or process, (ii) the cost of such clinical trials would be in excess of $ 50,000,000, (iii) it would take between seven to ten years to complete such clinical trials, (iv) there could be no assurance that even if Metacine could obtain the funding required to complete the clinical trials (which was well beyond Metacine's capability at the time Metacine acquired rights to the patent portfolio), that the clinical trials would have shown the product or process tested to be safe and effective. The Company's $1,850,000 obligation to Metacine, less the $400,000 Deficiency Payment made in October 2001, has been recorded as a current liability at December 31, 2002 and 2001. The $250,000 of services to be provided has also been recorded as a current liability. Services rendered to Metacine to date were immaterial and as such, the liability remained unchanged at December 31, 2002 and 2001. The investment has been further reduced to zero at December 31, 2001, by the Company's equity in the loss of Metacine of $158,582 for the period from April 9, 2001 through December 31, 2001. On April 1, 2003, the license granted by the University of Pittsburgh to Metacine covering Metacine's technology was terminated due to non-payment by Metacine. Accordingly, the Company's has not reflected its share of its equity in the losses in Metacine for the years ended December 31, 2002 and 2001 in the amounts of $274,846 and $290,994, respectively. The Company is currently in discussions with Metacine with respect to a full settlement of the Company's obligations to Metacine. Note 8. Inventories Inventories, consisting of material, labor and overhead, are classified as follows: December 31, 2002 2001 ------------------------- As Restated (See Note 4) Finished goods $ 322,518 $ 1,263,696 Work in process 3,052,070 3,052,070 Raw materials 1,332,560 1,332,560 Less reserve for excess inventory (4,678,659) (5,538,413) ----------- ------------ $ 28,489 $ 109,913 =========== ============ Finished goods inventory consists of vials of ALFERON N Injection, available for commercial and clinical use either immediately or upon final release by quality assurance. In light of the results of the Company's Phase 3 studies of ALFERON N Injection in HIV and HCV-infected patients, the Company has recorded a reserve against its inventory of ALFERON N Injection to reflect its estimated net realizable value. The reserve was a result of the Company's assessment of anticipated near-term projections of product to be sold or utilized in clinical trials, giving consideration to historical sales levels. As a result, inventories at December 31, 2002 and 2001, reflect a reserve for excess inventory of $4,678,659 and $5,538,413, respectively. Note 9. Convertible Notes Payable In August 2002, the Company completed a private placement of $500,000 of convertible notes to accredited investors. Each note is convertible into the Company's common stock at a price of $.05 per share (subject to adjustment to 70% of the market price of the Company's common stock under certain circumstances) and bears interest at the rate of 10% per annum. $250,000 of the convertible notes is due January 31, 2003 and the other $250,000 of the convertible notes is due December 31, 2003. For each $100,000 principal amount of notes issued, the investors received warrants to purchase an additional 10.2 million shares of the Company's common stock exercisable at $.01 per share. The warrants were valued at $400,000 and are amortized as interest expense over the terms of the respective notes. The transaction is subject to approval by the shareholders of the Company. In the event that shareholder approval is not obtained, the convertible noteholders could exercise their rights and call a default making the convertible notes immediately due and payable. In addition, these notes are convertible into common stock at a beneficial rate. The beneficial conversion feature is valued at $100,000 and accounted for as debt discount and is being amortized over the term of the notes. Note 10. Income Taxes As a result of the loss allocation rules contained in the Federal income tax consolidated return regulations, approximately $5,900,000 of net federal operating loss carryforwards, which expire from 2003 to 2006, are available to the Company upon ceasing to be a member of GP Strategies's consolidated return group in 1991. In addition, the Company has net federal operating loss carryforwards for periods subsequent to May 31, 1991, and through December 31, 2002 of approximately $104,000,000 that expire from 2006 to 2022. In addition, the Company had state net operating loss carryforwards of approximately $32,000,000 that expire from 2005 to 2009. The Company believes that the events culminating with the closing of its Common Stock Private Offering on November 6, 2000 may result in an "ownership change" under Internal Revenue Code, Section 382, with respect to its stock. The Company believes that as a result of the ownership change, the future utility of its pre-change net operating losses may be significantly limited. Further, the issuance of 51,000,000 warrants in August 2002 could also result in an ownership change and further limit use of the net operating losses carried forward. The tax effects of temporary differences that give rise to deferred tax assets and liabilities consist of the following as of December 31, 2002 and 2001: Deferred tax assets 2002 2001 ------------------- ---- ----- Net operating loss carryforwards $39,530,000 34,551,000 Tax credit carry-forwards -- 150,000 Inventory reserve 1,872,000 2,114,000 Property and equipment, principally due to differences in basis and depreciation 661,000 588,000 In-process technology costs -- 937,000 ---------- ----------- Gross deferred tax asset 42,063,000 38,340,000 Valuation allowance (42,063,000) (38,340,000) ----------- ----------- Net deferred taxes $ --- $ --- =========== =========== A valuation allowance is provided when it is more likely than not that some portion of the deferred tax asset will not be realized. The Company has determined, based on the Company's history of annual net losses, that a full valuation allowance is appropriate. The change in the valuation allowance for 2002 and 2001 was $3,723,000 and $2,411,000, respectively. Based on the Company's net loss before income taxes in 2002, 2001 and 2000, the Company would have recorded a tax benefit. During each of these years, the Company recorded increases in the valuation allowance due to uncertainty regarding the realization of deferred taxes that reduced the Company's expected income tax benefit to zero in these years. The Company participates in the State of New Jersey's corporation business tax benefit certificate transfer program (the "Program"), which allows certain high technology and biotechnology companies to transfer unused New Jersey net operating loss carryovers to other New Jersey corporation business taxpayers. During 1999, the Company submitted an application to the New Jersey Economic Development Authority (the "EDA") to participate in the Program and the application was approved. The EDA then issued a certificate certifying the Company's eligibility to participate in the Program and the amount of New Jersey net operating loss carryovers the Company has available to transfer. Since New Jersey law provides that net operating losses can be carried over for up to seven years, the Company may be able to transfer its New Jersey net operating losses from the last seven years. The Program requires that a purchaser pay at least 75% of the amount of the surrendered tax benefit. During 2002, 2001 and 2000, the Company completed the sale of approximately $6.5 million, $12 million, and $19 million of its New Jersey tax loss carryovers and received $0.53 million, $0.97 million, and $1.48 million, which were recorded as a tax benefit from gains on sale of state net operating loss carryovers on its Consolidated Statement of Operations in 2002, 2001 and 2000, respectively. Note 11. Common Stock, Stock Options, Warrants and Other Shares Reserved The Company has a stock option plan (the "Plan"), which authorizes a committee of the Board of Directors to grant options, to purchase shares of Common Stock, to officers, directors, employees and consultants of the Company. Pursuant to the terms of the Plan, no option may be exercised after 10 years from the date of grant. The Plan permits options to be granted at a price not less than 85% of the fair market value, however, the options granted to date have been at fair market value of the common stock at the date of the grant. Employee stock option activity for options under the Plan during the periods indicated is as follows: Number of Weighted-Average Shares Exercise Price ---------- ---------------- Balance at December 31, 1999 1,887,260 $ .25 Granted 61,710 1.10 Forfeited (2,580) .25 ---------- Balance at December 31, 2000 1,946,390 .28 Exercised (2,244) .25 Forfeited (13,525) .35 ---------- Balance at December 31, 2001 1,930,621 .28 Forfeited (22,546) .41 ---------- Balance at December 31, 2002 1,908,075 .27 At December 31, 2002, the exercise prices and weighted-average remaining contractual life of outstanding options were: Number of Options Life ------- ---- $ .25 - $1.00 1,854,475 1 year $1.01 - $1.25 53,600 1 year At December 31, 2002, the number of options exercisable was 1,908,075, and the weighted-average exercise price of those options was $.27. FASB Interpretation No. 44 provides guidance for applying APB Opinion No. 25, "Accounting for Stock Issued to Employees" ("FIN 44"). It applies prospectively to new awards, exchanges of awards in a business combination, modifications to outstanding awards, and changes in grantee status on or after July 1, 2000, except for provisions related to repricings and the definition of an employee that apply to awards issued after December 15, 1998. The Company has evaluated the financial impact of FIN 44 and has determined that the repricing of employee stock options on October 27, 1999 falls within the guidance of FIN 44. On October 27, 1999, the Company repriced 429,475 stock options to $.25 per share. On July 1, 2000, the implementation date of FIN 44, 352,823 shares of the 429,475 shares were fully vested (exercisable) and the closing price of the Company's common stock on such date was $1.63 per share. Beginning on and after July 1, 2000, the Company is required to record compensation expense on the repriced vested options only when the market price exceeds $1.63 per share and only on the amount in excess of $1.63 per share. For the repriced unvested stock options, the intrinsic value measured at the July 1, 2000 effective date that is attributable to the remaining vesting period will be recognized over that future period. The unvested stock options at July 1, 2000 (76,652) were fully vested on January 1, 2001. On December 31, 2002, the closing price of the Company's common stock was $.05 per share and accordingly, under FIN 44, no compensation expense was recorded on the repriced fully vested stock options of July 1, 2000 and on the repriced unvested stock options of July 1, 2000. Information regarding all Options and Warrants Changes in options and warrants outstanding during the years ended December 31, 2002, 2001 and 2000, and options and warrants exercisable and shares reserved for issuance at December 31, 2002 are as follows: The following table includes all options and warrants including employee options (which are discussed above). Price Range Number of Per Share Shares ----------- --------- Outstanding at December 31, 1999 $ .25 - $77.90 2,567,032 Granted .56 - 1.50 14,631,279 Terminated .25 - 77.90 (90,975) --------------------- ----------- Outstanding at December 31, 2000 .25 - 48.00 17,107,336 Exercised .25 (2,244) Terminated .25 - 48.00 (77,938) --------------------- ----------- Outstanding at December 31, 2001 .25 - 36.00 17,027,154 Warrants Issued .01 - .01 51,000,000 Terminated .25 - 36.00 (49,510) --------------------- ---------- Outstanding at December 31, 2002 .01 - 1.50 67,977,644 ========== Exercisable: December 31, 2002 .25 - 1.50 16,977,644 ========== Shares reserved for issuance: December 31, 2002 67,977,644 ========== Options and warrants outstanding and exercisable, and shares reserved for issuance at December 31, 2002, include 500,000 shares under a warrant agreement with GP Strategies. The warrants are priced at $1.00 per share and expire on March 25, 2004. Options and warrants outstanding and exercisable, and shares reserved for issuance at December 31, 2002, include 11,635,451 shares under warrant agreements with the purchasers of a 2000 private offering. The warrants are priced at $1.50 per share and expire on April 17, 2005. Options and warrants outstanding and exercisable, and shares reserved for issuance at December 31, 2002, include 2,934,118 shares under a warrant agreement to purchase 1,467,059 units. Each unit consists of a share of common stock and a warrant to purchase an additional share of common stock at a price of $1.50 per share, exercisable at a price of $.66 per unit. The units were issued as compensation for services rendered to the Company in the 2000 private offering and expire on April 17, 2005. Options and warrants outstanding and shares reserved for issuance, at December 31, 2002, include 51,000,000 shares under warrant agreements (subject to shareholder approval) with the purchasers of the convertible notes. The warrants are exercisable at $.01 per share upon shareholder approval and expire in 2007. Note 12. Savings Plan The ISI Savings Plan (the "Savings Plan") permits pre-tax contributions to the Savings Plan by participants pursuant to Section 401(k) of the Internal Revenue Code of up to 15% of base compensation. The Company will match up to the 6% level of the participants' eligible contributions. The Savings Plan matches 40% in cash and 60% in the Company's common stock up to the 6% level. For 2002, the Company's contribution to the Savings Plan, which was fully vested, was $131,000, consisting of $52,657 in cash and $78,343 in stock. For 2001, the Company's contribution to the Savings Plan was $176,000, consisting of $66,666 in cash and $109,334 in stock. For 2000, the Company's contribution to the Savings Plan was $124,000, consisting of $43,802 in cash and $80,198 in stock. Note 13. Common Stock Compensation and Profit Sharing Plan Common Stock Compensation Plan Effective October 1, 1997, the Company adopted the Common Stock Compensation Plan (the "Stock Compensation Plan"), providing key employees with the opportunity of receiving the Company's common stock as additional compensation. Pursuant to the terms of the Stock Compensation Plan, key employees were to receive, as additional compensation, a pre-determined amount of the Company's common stock in three equal installments on October 1, 1998, 1999 and 2000, provided that the key employees remain in the employ of the Company at each such installment date. As of October 1, 2000, 1999 and 1998, a deferred compensation liability of $289,920, $340,821 and $412,344, respectively, was accrued for these employees based on the common stock market price of October 1, 1997. On October 1, 2000, 1999 and 1998, the Company paid the compensation in cash in settlement of the Company's obligation to issue shares of common stock. Accordingly, cash of $7,414, $2,131, and $25,947, respectively, was paid in satisfaction of the accrued liability of $289,920, $340,821 and $412,344, respectively. The difference of $282,506, $338,690, and $386,397 was credited to additional paid in capital in 2000, 1999 and 1998, respectively. Profit Sharing Plan The Company has a Profit Sharing Plan (the "Profit Sharing Plan") providing key employees and consultants with an opportunity to share in the profits of the Company. The Profit Sharing Plan is administered by the Company's Compensation Committee. Pursuant to the terms of the Profit Sharing Plan, the Compensation Committee, in its sole discretion, based upon the significance of the employee's contributions to the operations of the Company, selects certain key employees and consultants of the Company who are entitled to participate in the Profit Sharing Plan and determines the extent of their participation. The amount of the Company's profits available for distribution to the participants (the "Distribution Pool") is the lesser of (a) 10% of the Company's income before taxes and profit sharing expense and (b) an amount equal to 100% of the base salary for such year of all the participants in the Profit Sharing Plan. The Compensation Committee may require as a condition to participation that a participant remain in the employ of the Company until the end of the fiscal year for which payment is to be made. Payments required to be made under the Profit Sharing Plan must be made within 10 days of the filing of the Company's tax return. To date, there have been no contributions by the Company under the Profit Sharing Plan. Note 14. Related Party Transactions GP Strategies owns less than 5% of the Company's common stock as of December 31, 2002. The Company was a party to a management agreement with GP Strategies, pursuant to which certain legal, financial and administrative services had been provided by employees of GP Strategies. The management agreement was terminated on March 27, 2000 (See Note 16). See Note 16 for information with respect to royalty obligations to GP Strategies. Note 15. Supplemental Statement of Cash Flow Information The Company paid no income taxes or interest during the three-year period ended December 31, 2002. During the years ended December 31, 2002, 2001 and 2000 the following non-cash financing and investing activities occurred: 2002: None 2001: The Company issued 2,000,000 shares, with a guaranteed value of $1,850,000, of common stock and committed to provide $250,000 of services to be rendered by the Company to Metacine (see Note 7). The Company reduced capital in excess of par value and the corresponding liability by $21,463 for settlement shares sold. 2000: The Company issued 870,000 shares of common stock as payment related to accounts payable (see Note 16). The Company credited capital in excess of par value for forgiveness of $129,886 of debt due GP Strategies. The Company reduced capital in excess of par value and the corresponding liability by $382,515 for settlement shares sold. Note 16. Commitments The Company obtained human white blood cells used in the manufacture of ALFERON N Injection from several sources, including the Red Cross pursuant to a supply agreement dated April 1, 1997 (the "Supply Agreement"). The Company will not need to purchase more human white blood cells until such time as production of crude alpha interferon is resumed. Under the terms of the Supply Agreement, the Company was obligated to purchase a minimum amount of human white blood cells each month through March 1999 (the "Minimum Purchase Commitment"), with an aggregate Minimum Purchase Commitment during the period from April 1998 through March 1999 in excess of $3,000,000. As of November 23, 1998, the Company owed the Red Cross approximately $1.46 million plus interest at the rate of 6% per annum accruing from April 1, 1998 (the "Red Cross Liability") for white blood cells purchased pursuant to the Supply Agreement. Pursuant to an agreement dated November 23, 1998, the Company granted the Red Cross a security interest in certain assets to secure the Red Cross Liability, issued to the Red Cross 300,000 shares of common stock and agreed to issue additional shares at some future date as requested by the Red Cross to satisfy any remaining amount of the Red Cross Liability. The Red Cross agreed that any net proceeds received by it upon sale of such shares would be applied against the Red Cross Liability and that at such time as the Red Cross Liability was paid in full, the Minimum Purchase Commitment would be deleted effective April 1,1998 and any then existing breaches of the Minimum Purchase Commitment would be waived. In January 1999 the Company granted the Red Cross a security interest (the "Security Interest") in, among other things, the Company's real estate, equipment inventory, receivables, and New Jersey net operating loss carryovers to secure repayment of the Red Cross Liability, and the Red Cross agreed to forbear from exercising its rights under the Supply Agreement, including with respect to collecting the Red Cross Liability until June 30, 1999 (which was subsequently extended until December 31, 1999). On December 29, 1999, the Company, the Red Cross and GP Strategies entered in an agreement pursuant to which the Red Cross agreed that until September 30, 2000 it would forbear from exercising its rights under (i) the Supply Agreement, including with respect to collecting the Red Cross Liability, and (ii) the Security Interest. In connection with the Asset Sale Transactions, the Company, HEB and the Red Cross entered into a similar agreement pursuant to which the Red Cross agreed to forbear from exercising its rights until May 31, 2003 and the Red Cross agreed to accept HEB common stock with a guaranteed value of $500,000 in full settlement of all of the Company's obligations to the Red Cross. Under the terms of such agreement, if HEB does not make such payment, the Red Cross has the right to sell the Company's real estate. During 1999, the Red Cross sold 27,000 of the Settlement Shares and sold the balance of such shares (273,000 shares) during the first quarter of 2000. As a result, the net proceeds from the sales of the Settlement Shares, $33,000 in 1999 and $368,000 in 2000, were applied against the liability to the Red Cross. The remaining liability to the Red Cross included in accounts payable on the consolidated balance sheet at December 31, 2002 and 2001 was approximately $1,403,000 and $1,339,000, respectively. On October 30, 2000, the Company issued an additional 800,000 shares to the Red Cross. The net proceeds from the sale of such shares by the Red Cross will be applied against the remaining liability of $1,403,000 owed to the Red Cross. However, there can be no assurance that the net proceeds from the sale of such shares will be sufficient to extinguish the remaining liability owed the Red Cross. Pursuant to an agreement dated March 25, 1999, GP Strategies loaned the Company $500,000. In return, the Company granted GP Strategies (i) a first mortgage on the Company's real estate, (ii) a two-year option (which has expired) to purchase the Company's real estate, provided that the Company has terminated its operations and the Red Cross Liability has been repaid, and (iii) a two-year right of first refusal (which has expired) in the event the Company desires to sell its real estate. In addition, the Company issued GP Strategies 500,000 shares of Common Stock and a five-year warrant to purchase 500,000 shares of Common Stock at a price of $1 per share. The common stock and warrants issued to GP Strategies were valued at $500,000 and recorded as a financing cost and amortized over the original period of the GP Strategies Debt in 1999. Pursuant to the agreement, the Company has issued a note to GP Strategies representing the GP Strategies Debt, which note was originally due on September 30, 1999 (but extended to June 30, 2001) and bears interest, payable at maturity, at the rate of 6% per annum. In addition, at that time the Company negotiated a subordination agreement with the Red Cross pursuant to which the Red Cross agreed that its lien on the Company's real estate is subordinate to GP Strategies' lien. On March 27, 2000, the Company and GP Strategies entered into an agreement pursuant to which (i) the GP Strategies Debt was extended until June 30, 2001 and (ii) the Management Agreement between the Company and GP Strategies was terminated and all intercompany accounts between the Company and GP Strategies (other than the GP Strategies Debt) in the amount of approximately $130,000 were discharged which was recorded as a credit to capital in excess of par value. On August 23, 2001, the Company and GP Strategies entered into an agreement pursuant to which the GP Strategies Debt was extended to March 15, 2002. During 2001, the Company paid GP Strategies $100,000 to reduce the GP Strategies Debt. In addition, in January 2002, the Company paid GP Strategies $100,000 to further reduce the GP Strategies Debt. Interest expense accrued to GP Strategies was $18,000, $27,937 and $22,500 for the years ended December 31,2002, 2001 and 2000, respectively. In connection with the Asset Sale Transactions, the Company, HEB and GP Strategies entered into a similar agreement pursuant to which GP Strategies agreed to forbear from exercising its rights until May 31, 2003 and GP Strategies agreed to accept HEB common stock with a guaranteed value of $425,000 in full settlement of all the Company's obligations to GP Strategies. Under the terms of such agreement, if HEB does not make such payment, GP Strategies has the right to sell the Company's real estate. As consideration for the transfer to the Company of certain licenses, rights and assets upon the formation of the Company by GP Strategies, the Company agreed to pay GP Strategies royalties of $1,000,000, but such payments will be made only with respect to those years in which the Company has income before income taxes, and will be limited to 25% of such income. Through December 31, 2002, the Company has not generated income before taxes and therefore has not accrued or paid royalties to GP Strategies. See Notes 5 and 6 for information relating to royalties payable to Hoffmann and the Partnership, respectively.

Note 18. Fair Value of Financial Instruments The carrying values of financial instruments, assuming the Company continues as a going concern, including cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and note payable approximate fair values, because of the short term nature or interest rates that approximate current rates. Note 19. Agreement with Mayo In April 2001, the Company entered into a technology license agreement with Mayo Foundation for Medical Education and Research ("Mayo") under which the Company obtained certain technology rights. The Company has committed to fund approximately $400,000 of costs related to a clinical trial beginning in December 2001 and which is currently expected to take at least two years from the date hereof to complete. The Company paid Mayo $100,000 related to this clinical trial in 2001, incurred $101,565 in 2002 and will owe other amounts upon the completion of certain parts of the trial, with the last payment due upon receipt of the final written report on the trial. The Company can terminate this agreement up to 60 days after receipt of this report. After expiration of this ability to terminate, the Company must issue 25,000 shares of the Company's common stock to Mayo and must pay milestone payments upon certain regulatory or other events and royalties on future sales, if any. In addition, the Company paid $60,000 to Mayo related to the agreement in 2001. Under the terms of the Asset Sales Transactions, the Company's right to continue this agreement and the obligation owed to Mayo was transferred to HEB. The Company did not generate any revenues from this agreement for each of the three years ended December 31, 2002. Note 20. Subsequent Event On March 11, 2003, the Company sold all its inventory related to its ALFERON N Injection product and granted a license to sell the product to Hemispherx Biopharma, Inc. ("HEB"). In exchange for the inventory and license, the Company received HEB common stock with a guaranteed value of $675,000, an additional 62,500 shares of HEB common stock without a guaranteed value, and a royalty equal to 6% of the net sales of ALFERON N Injection. The HEB common stock will be subject to selling restrictions. In addition, HEB assumed approximately $400,000 of the Company's payables and various other commitments. The Company and HEB also entered into another agreement pursuant to which the Company will sell to HEB, subject to regulatory approval, the Company's real estate property, plant, equipment, furniture and fixtures, rights to ALFERON N Injection and all of its patents, trademarks and other intellectual property related to its natural alpha interferon business. In exchange, the Company will receive $675,000 of HEB common stock with a guaranteed value, an additional 62,500 shares of HEB common stock without a guaranteed value and a royalty equal to 6% of the net sales of all products sold containing natural alpha interferon. HEB will assume approximately $1.5 million of the Company's indebtedness that currently encumbers its assets. In addition, HEB will fund the operating costs of the Company's facility pending the completion of this transaction. In the event the Company does not obtain regulatory approval prior to September 12, 2003, either the Company or HEB may terminate the agreement and not complete the transaction. In March 2003, the Company sold 15,000,000 shares of its common stock in a private placement transaction to an investor for $150,000. In connection with this private placement, the Company also sold, for $1,000, 15,000,000 warrants exercisable at $.01 per share and expiring in March 2008. Item 9.

Each of the employees can terminate his employment agreement for Good Reason, which is defined as (i) a change in control of the Company or (ii) a failure by the Company to comply with any material provision of the employment agreement which has not been cured within ten days after notice. A "change in control" of the Company is defined as (i) a change in control of a nature that would be required to be reported in response to Item 1(a) of Current Report on Form 8-K pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 (the "Exchange Act"), (ii) any "person" (as such term is used in Sections 13(d) and 14(d) of the Exchange Act) is or becomes the "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing 20% or more of the combined voting power of the Company's then outstanding securities, or (iii) at any time individuals who were either nominated for election or elected by the Board of Directors of the Company cease for any reason to constitute at least a majority of the Board.

If the employment agreement is terminated for any reason other than Cause, the Company is required to maintain in full force and effect, for a number of years equal to the greater of (i) the number of years (including partial years) that would have been remaining in the employment period if the employment agreement had not so terminated and (ii) three (one and one-half in the case of Dr. Ronel), all employee benefit plans and programs in which the employee was entitled to participate immediately prior to the termination date.

(the "Company") on Form S-8 (No. 333-49386) of our report dated June 10, 2003 on our audit of the consolidated financial statements of the Company as of December 31, 2002 and 2001 and for each of the years in the three-year period ended December 31, 2002, and the related financial statement schedule, which report is included in this Annual Report on Form 10-K. Our report contains an explanatory paragraph that states the Company has suffered recurring losses from operations, has an accumulated deficit, a working capital deficiency, and has limited liquid resources. These factors raise substantial doubt about the Company's ability to continue as a going concern. The consolidated financial statements do not include any adjustments that might result from the outcome of that uncertainty. Eisner LLP New York, New York August 4, 2003
