PART I


Item 1. Business

(a) General Development of Business

Interferon Sciences, Inc. (the "Company") is a biopharmaceutical company
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 N Injection(R) (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 is being studied
for potential use in the treatment of HIV, hepatitis C, and other indications.
The Company also is studying ALFERON N Gel(R) and ALFERON LDO(R), the Company's
topical and oral formulations of Natural Alpha interferon, for the potential
treatment of viral and immune system diseases.

(b) Financial Information about Business Segments.

The Company operates as a single line of business. For the years ended
December 31, 1998, 1997 and 1996, domestic sales totaled $1,716,157, $2,613,430
and $1,809,595, respectively, and foreign sales (primarily Germany) totaled
$214,500, $314,155 and $130,000, 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 three ALFERON products
contain a 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 17 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, only two types of alpha interferon are approved for commercial sale:
recombinant (genetically engineered) alpha interferon and Natural Alpha
Interferon, which is manufactured from human white blood cells. Outside of the
United States, sales of alpha interferon produced by cell culture account for a
significant portion of the market.

The Company believes that the potential advantages of Natural Alpha
Interferon over recombinant interferon 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 responsible for the production of interferon-neutralizing
antibodies seen in patients treated with recombinant alpha interferon.

The production of Natural Alpha Interferon is dependent upon a supply
of human white blood cells and other essential materials. The Company currently
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. Genital warts, a
sexually transmitted disease, are caused by certain types of human papilloma
viruses. 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
is often difficult to achieve. A topical formulation of an interferon inducer
has also recently been approved by the FDA for the treatment of genital warts.
The Company is unable to predict the effect this approval will have on the
Company's sales of Alferon N Injection.

Clinical Trials for New Indications. In an effort to obtain approval to
market ALFERON N Injection for additional indications in the United States and
around the world, the Company is focusing its research program on conducting and
planning various clinical trials for new indications.




HIV-infected patients. The Human Immunodeficiency Virus ("HIV")
infection is at epidemic levels in the world. The World Health Organization
projects that this virus will affect 30 to 40 million people by the year 2000.
HIV infection usually signals the start of a progressive disease that
compromises the immune systems, ultimately resulting in Acquired Immune
Deficiency Syndrome ("AIDS"). The United States Centers for Disease Control
estimates that as of the middle of 1997, there were approximately 259,000 cases
of AIDS in the United States. A recent study in the Journal of the American
Medical Association estimated that 650,000 to 900,000 U.S. residents were living
with HIV infection.

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 10 to 100 times more effective than equal concentrations of
recombinant alpha interferon 2a and 2b, respectively, 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 with
asymptotic HIV-infected patients 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 after
an average of 16 months after treatment, CD4 white blood cell counts remained
essentially unchanged or were higher than at the onset of the trial in 11 of 20
patients. In addition, 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 microliter and a viral burden (as determined by PCR testing) of at least
2,000 RNA copies per milliliter. The Company completed the preliminary analysis
of the data collected from the 16 investigator sites and scheduled 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 such patients
with high CD4 counts, the study's primary efficacy variable (reduction in viral
load) was not met at the time point specified in the protocol (end of
treatment). The FDA therefore indicated that an additional trial will be
necessary to evaluate further the efficacy of ALFERON N Injection for this
indication. The Company does not currently intend to pursue this program until
it obtains substantial additional funding or enters into a collaboration with
another company for such purpose.

There can be no assurance that ALFERON N Injection for the treatment of
patients with HIV will be cost-effective, safe, and effective or that the
Company will be able to obtain FDA approval for such use. Furthermore, even if
such approval is obtained, there can be no assurance that such product will be
commercially successful or will produce significant Revenues or profits for the
Company.

Hepatitis C. Chronic viral hepatitis is a liver infection caused by various
hepatitis viruses. The United States Centers for Disease Control estimates that
nearly four million people in the United States are presently infected with the
hepatitis C virus ("HCV"), a majority of whom become chronic carriers and will
suffer gradual deterioration of their liver and possibly cancer of the liver.
Several brands of recombinant and cell-cultured interferon have been approved by
various regulatory agencies worldwide for the treatment of hepatitis C,
including three recombinant products in the United States. 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-centers,
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. 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 response at the
end of treatment in 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.

As a result of 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 the second quarter of
1996 a Phase 3 multi-center, randomized, controlled clinical trial designed to
evaluate the safety and efficacy of ALFERON N Injection 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 recently completed the
final analysis of the data and in March, 1999, requested a meeting with the FDA
to determine the acceptability of the results for filing purposes. If the FDA
grants this request, the Company anticipates that this meeting will occur in the
second quarter of 1999. If the FDA determines that the results appear to be
acceptable for filing purposes, the Company intends to seek FDA approval in the
second quarter of 1999. However, there can be no assurance that FDA approval
will be obtained for this use or, even if obtained, that the use of ALFERON N
Injection for the treatment of patients with hepatitis C will be commercially
successful or will produce significant revenues or profits for the Company.




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. The trial consists of a 24-week treatment phase,
with an option to extend treatment an additional 24 weeks if certain response
criteria are met and a 24-week follow-up phase. Two groups of patients with
chronic hepatitis C are being studied - one with significant HIV viral levels
and the other with low or undetectable levels. The patients' HIV and HCV viral
levels are being evaluated throughout the treatment and follow-up phases. It is
estimated that approximately 10% of HIV-infected patients are co-infected with
HCV.

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, Copaxone(R), a non-interferon product was recently
approved by the FDA to treat relapsing-remitting multiple sclerosis. Based in
part on encouraging anecdotal reports on the use of ALFERON N Injection in MS
patients, the Company would like to conduct a clinical trial in order to
investigate the potential use of ALFERON N Injection for the treatment of MS.
However, the timing of this trial will be dependent upon the Company's ability
to obtain additional funding or a sponsor.

Marketing and Distribution. The Company completed the reacquisition of
marketing and distribution rights for ALFERON N Injection from The Purdue
Frederick Company ("Purdue") in May 1996. The Company believes that the
reacquisition of marketing provides it with greater flexibility and control over
the distribution of ALFERON N Injection, although the Company does not have its
own sales force. Since the reacquisition, the Company has focused its efforts in
the United States on making additional sales to existing customers. In June
1998, the Company entered into an agreement appointing Integrated
Commercialization Solutions, Inc. ("ICS"), a subsidiary of Bergen Brunswig
Corporation, and the sole United States distributor of ALFERON N Injection.
Pursuant to such agreement, ICS will also provide clinical and product
information, reimbursement information and services, and management of patient
assistance services.

In 1996, the Company entered into a supply and distribution agreement (the
"Cell Pharm Agreement") with Cell Pharm GmbH ("Cell Pharm"). Cell Pharm,
headquartered in Hanover, Germany, is a privately owned pharmaceutical company
primarily involved in the distribution and manufacture of products for cancer
treatment and other uses. The Cell Pharm Agreement, which terminates on June 30,
2001, unless renewed, grants Cell Pharm rights to distribute, promote, and sell
ALFERON N Injection in Germany. The Cell Pharm Agreement provides that the
Company will supply Cell Pharm with ALFERON N Injection at specified prices. In
addition, Cell Pharm is required to pay the Company 50% of the incremental
revenue Cell Pharm receives as a result of selling ALFERON N Injection at a
price higher than a specified price. Cell Pharm is required to maintain active
and efficient sales and customer service organization with adequately trained
personnel for marketing and selling ALFERON N Injection. Cell Pharm represents
to the Company that it has obtained, and Cell Pharm agrees to maintain in
effect, all registrations, approvals, and consents from governments in Germany
as are necessary to permit or facilitate the lawful handling, promotion, and
resale of ALFERON N Injection in Germany. Cell Pharm has informed the Company
that it intends to market ALFERON N Injection under the trade name
Cytoferon(TM), pursuant to Cell Pharm's existing regulatory approval to market
Cytoferon in Germany for the treatment of hairy cell leukemia and for the
treatment of patients who develop antibodies against recombinant alpha
interferons.

In February 1994, the Company entered into an exclusive distribution
agreement for ALFERON N Injection in Mexico with Industria Farmaceutica
Andromaco, S.A. de C.V. ("Andromaco"), a privately-held pharmaceutical company
headquartered in Mexico City which specializes in oncology and immunology
products. Pursuant to the agreement, Andromaco obtained approval from the
Mexican regulatory authorities to sell ALFERON N Injection for the treatment of
genital warts, which is marketed under the trade name ALTEMOL(R). The agreement
establishes performance milestones for the maintenance of distribution rights by
Andromaco in Mexico. In addition, the Company has a buy-out option to reacquire
the marketing and distribution rights in Mexico under certain terms and
conditions. To date, sales of Alferon N Injection to Andromaco have been
insignificant.

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
Laboratories Inc. ("Abbott") pursuant to a processing and supply agreement
entered into in September 1994. Under the terms of the agreement with Abbott,
the Company pays Abbott an agreed price to formulate and package ALFERON N
Injection in accordance with specifications provided by the Company. At the
present time, the Company has produced sufficient inventory to satisfy its
clinical and commercial needs for the foreseeable future and has therefore
discontinued production of ALFERON N Injection. See "Business -- ALFERON N
Injection -- Clinical Trials for New Indications," "Management's Discussion and
Analysis of Financial Condition and Results of Operations," "Business
- -Governmental Regulation," and "Properties."




Competition. Presently, INTRON A, manufactured by Schering Plough Corp.
"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 March 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 products developed by the Company's
competitors or advances in other methods of the treatment of genital warts will
have on the commercial viability of its product.

If and when the Company obtains approvals for additional indications of
ALFERON N Injection and its proposed products (such as the approval obtained by
Cell Pharm in Germany), 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.

A number of synthetic antiviral compounds have been approved in the United
States and certain foreign countries for the treatment, primarily in combination
therapy, of HIV infection and AIDS. Shown in Table 1 below are the drugs which
are currently approved in the United States for the treatment of patients
infected with HIV.

Schering's recombinant interferon product is already approved for the
treatment of hepatitis C and hepatitis B in the United States and other markets,
as well as for many other medical uses. Roche Pharmaceuticals's recombinant
interferon product has been approved for the treatment of hepatitis C in the
United States and for other medical uses in the United States and in foreign
countries. In addition, Amgen Inc.'s recombinant interferon, Infergen(R), also
known as consensus interferon product, is approved for the treatment of
hepatitis C in the United States.

In the United States, two recombinant forms of beta interferon, Biogen,
Inc.'s Avonex(R) and Berlex Laboratories' Betaseron(R) as well as Teva Marion
Partners' Copaxone(R), a non-interferon product, have been approved for the
treatment of 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.

ALFERON N Gel

ALFERON N Gel is a topical, Natural Alpha Interferon preparation, which the
Company has developed and believes, has potential in the treatment of cervical
dysplasia, intravaginal warts, and mucocutaneous and genital herpes.

Clinical Trials. The Company has completed one clinical trial, has
commenced one clinical trial, and may conduct other clinical trials for its
ALFERON N Gel formulation to develop applications and obtain initial approvals
for such products.

Cervical Dysplasia and Intravaginal Warts. Affecting approximately 500,000
to one million women each year in the United States alone, cervical dysplasia,
or abnormal cervical cells, has been identified as a potential precursor to
cervical cancer. Cervical cancer strikes approximately 13,000 women in the
United States each year, causing 5,000 deaths, and is responsible for more than
half a million deaths worldwide. Cervical dysplasia is caused by certain strains
of the human papillomavirus ("HPV"), the same family of viruses that causes
genital warts. The Company has completed a small Phase 2 dose-ranging study
using ALFERON N Gel at the Columbia-Presbyterian Medical Center in New York for
the treatment of mild cervical dysplasia. Pap smears, identification tests for
the presence of virus, and cervical biopsies indicated that ALFERON N Gel
appears to have the potential for improving the course of cervical dysplasia in
the majority of patients who completed the treatment course. In addition, an
investigator-sponsored, Phase 2 randomized, placebo-controlled, double-blind,
parallel group clinical study to investigate the potential use of ALFERON N Gel
for the treatment of intravaginal warts (which are also caused by the HPV) is
currently in progress. However, patient recruitment has been very slow and the
addition of a second site is being considered.

Other Widespread Dermatological Lesions Potentially Treatable with ALFERON
N Gel Therapy. Nearly 30 million people in the U.S. are infected with the herpes
simplex type II virus, which is the infectious virus that causes genital herpes.
Up to 500,000 new cases are reported each year, according to the Alan Guttmacher
Institute. To date, there is no cure for genital herpes. Preliminary findings
with a previous formulation of recombinant interferon in the Company's
proprietary gel showed significant shortening of the contagious period and
relief of symptoms, but the Company will not start clinical trials unless
additional funding or a sponsor is secured.

ALFERON N Gel may also be of benefit to immunocompromised patients with
mucocutaneous herpes. Patients with this form of herpes suffer from persistent
skin lesions, which have become resistant to existing therapies. The Company
will not start clinical trials for this indication unless additional funding or
a sponsor is secured.

Marketing and Distribution. The Company does not have any marketing
agreement with respect to ALFERON N Gel and, if FDA approval is obtained, no
assurance can be given that the Company will be able to enter into a marketing
agreement on terms satisfactory to the Company. The Company may also choose to
market ALFERON N Gel itself if FDA approval is obtained.

Competition. The Company believes that three antiviral products are
presently sold in the United States for the treatment of recurrent genital
herpes: Zovirax(R) (manufactured by Glaxo Wellcome Inc.) which contains
acyclovir and is administered orally, topically, or intravenously, Famvir(R)
(manufactured by SmithKline Beecham Pharmaceuticals) which contains famcyclovir
and is administered orally, and Valtrex(R) (manufactured by Glaxo Wellcome,
Inc.) which contains valacyclovir and is also administered orally. The only
current treatment for cervical dysplasia in the United States is surgery, while
intravaginal warts are treated with ablative therapy.

ALFERON LDO

ALFERON LDO is a low dose oral liquid Natural Alpha Interferon preparation
which the Company has developed and believes has potential in the treatment of
several quality-of-life parameters of importance to patients infected with HIV.

Clinical Trials for ALFERON LDO. As described below, the Company has
completed two Phase 2 clinical trials for its ALFERON LDO formulation for the
treatment of HIV-infected patients. In addition, a National Institute of Allergy
and Infectious Diseases ("NIAID") sponsored Phase 3 trial in HIV-infected
patients has been concluded in which ALFERON LDO was included as one of the
treatments.

HIV-infected patients. The Company has completed two double-blind studies
at Mount Sinai Medical Center in New York involving ALFERON LDO. One was a
placebo-controlled study in AIDS-related complex ("ARC") patients, and the other
was a dose ranging study in AIDS or ARC patients. The results from the
placebo-controlled study did not demonstrate a significant improvement or
alteration in the expected progression of the disease, although patients
receiving ALFERON LDO reported greater energy and appetite than those given the
placebo. The results from the dose ranging study indicate that one of the doses
may promote weight gain and an increase in energy and overall well-being. At the
insistence of AIDS groups and community-based physicians who had been using
low-dose oral formulations of interferon in their practice, the NIAID launched
in the second quarter of 1996 a Phase 3 trial of three preparations of low-dose
oral interferon, including ALFERON LDO. An advisory committee comprised of
representatives from the Company and other interferon manufacturers, AIDS
support groups, the FDA, and the National Institutes of Health was organized to
design this multicenter study, which is examining the effectiveness of low dose
oral alpha interferon therapy on several quality-of-life parameters of
importance to patients infected with HIV. Patients enrolled in the study were




randomly assigned to one of four treatment groups, with all participants
receiving three compounds. In three of the groups, patients received one active
compound and two placebos. Patients in the fourth group received only placebos.
Neither the physician nor the patient will know which group the patient was
assigned to until after the study, which had a six-month treatment phase and
six-month follow-up period, has ended and the analysis is completed. While in
the study, patients were permitted to take antiretroviral drugs and therapies
against opportunistic infections. In June 1997, NIAID terminated enrollment in
this study because of the slow rate of patient accrual. NIAID will analyze and
publish the results of the completed patients when available. The Company has
provided clinical quantities of ALFERON LDO for use in the study.

Marketing and Distribution. The Company does not have a marketing agreement
with respect to ALFERON LDO and, if FDA approval of ALFERON LDO is obtained, no
assurance can be given that the Company will be able to enter into a marketing
agreement for such products on terms satisfactory to the Company. The Company
may also choose to market ALFERON LDO itself if FDA approval is obtained.

Competition. Under the terms of a licensing agreement (as amended, the
"Amarillo Agreement") with Amarillo Bioscience, Inc. (formerly Amarillo Cell
Culture Company, Incorporated) ("Amarillo") (i) the Company has the exclusive
right to sell ALFERON LDO, containing Natural Alpha Interferon, in the United
States and all foreign countries other than Japan, (ii) Amarillo and Pharma
Pacific Management Pty. Ltd. ("PPM"), a company which has also obtained a
license from Amarillo, each has the right to sell any interferon other than
Natural Alpha Interferon in the United States and all foreign countries other
than Japan, and (iii) Hayashibara Biochemical Laboratory has the right to sell
its low dose alpha interferon in Japan. See "Business -- Licenses and Royalty
Obligations." Therefore, with respect to low dose oral interferon products, the
Company will potentially compete with Amarillo and PPM in the United States and
in the rest of the world except Japan and with Hayashibara Biochemical
Laboratory in Japan. In addition, the Company will potentially compete with the
manufacturers of the synthetic antiviral compounds that have been approved in
the United States and certain foreign countries for the treatment of HIV and
AIDS. (See "Business -- ALFERON N Injection -- Competition").

Patents

In 1996, the Company was issued a United States patent, comprised of 15
claims, for Natural Alpha Interferon. The two major claims are for (i) a highly
purified Natural Alpha Interferon composition produced from human peripheral
blood leukocytes and (ii) an improved method to produce this composition. The
issuance of this patent gives the Company protection for the manufacture, use,
and sale of its Natural Alpha Interferon product in the United States and
prevents a competitor from producing or using equivalent products derived from
human peripheral blood leukocytes. Patent applications have also been filed in
selected foreign countries. In the fourth quarter of 1997, the Company was
issued a second United States patent, which broadens the scope of the first one
to cover certain individual or mixtures of alpha interferon species present in
Natural Alpha Interferon.

Also in 1996, the Company was issued a United States patent, comprised of
four claims that will expand the Company's portfolio on overall technologies in
the interferon field. The biological activities of interferon take place when
the interferon binds to Type 1-interferon receptor proteins, which are present
in various human cells. The major claim is the composition claim for an
interferon receptor protein specifically binding alpha and beta, but not gamma,
interferon. The receptor, which is isolated from a cancerous cell line, binds
both natural and recombinant alpha interferons and is a variant form of the
human interferon receptor (Type 1) which has been found in some cases of acute
leukemia. The claimed receptor protein could be used to produce anti-receptor
antibodies that may have potential use in diagnostic testing for tumors or
cancers which have an abnormal number of receptors. The claimed receptor protein
may also have potential use as a therapeutic agent for those diseases, which
have aberrant production of interferon, by binding to and neutralizing the
excess interferon.

The United States patent and Trademark Office has also issued two patents
to the Company, which disclose and claim topical interferon preparations. The
patents encompass interferon preparations for the topical delivery of one or
more interferons to the site of a disease which responds therapeutically to
interferon, and a system for delivering interferon topically which prevents
oxidation of the protein. The inventions specifically encompass the topical
treatment for treating viral diseases, such as herpes genitalis, with alpha
interferon. The Company has various other issued patents and patent applications
pending in the field of biotechnology, purification processes, and therapeutics.

Licenses and Royalty Obligations

F. Hoffmann-LaRoche Ltd. and Hoffmann-La Roche, Inc. (collectively,
"Hoffmann") have been issued patents covering human alpha interferon in many
countries throughout the world. As of March 31, 1995, the Company obtained a
non-exclusive perpetual license from Hoffmann (the "Hoffmann Agreement") which
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 replaced a 1988 non-exclusive license
which, as amended, granted the Company the right to make, use, and sell in the
United States, without a potential patent infringement claim from Hoffmann,
injectable formulations of Natural Alpha Interferon for the treatment of genital
warts or patients with diseases refractory to recombinant interferon therapy.
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. 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.

In October 1989, the Company entered into the Amarillo Agreement. Amarillo,
which is located in Amarillo, Texas, is in the business of the research and
development of animal health products and became a public company in 1996. Under
the terms of the Amarillo Agreement, the Company has a non-exclusive license
under all of Amarillo's issued patents, patent applications, and "know-how"
relating to the treatment of humans by the oral administration of Natural Alpha
Interferon in low doses. In addition, Amarillo has the right to purchase the
Company's Natural Alpha Interferon for use in the animal health market and is
obligated to pay royalties to the Company based upon sales using the Company's
Natural Alpha Interferon.

The Company will be obligated to pay Amarillo royalties of 10% on the sales
of Natural Alpha Interferon products using Amarillo's patented technology as
determined under the Amarillo Agreement. In addition, the Company is a party to
certain license agreements, including the Hoffmann Agreement, pursuant to which
it is obligated to pay royalties based upon commercial exploitation of ALFERON N
Gel and ALFERON LDO. Under the terms of such license agreements, the Company
would pay royalties of up to 13.5% and 19.5% of net sales of ALFERON N Gel and
ALFERON LDO, respectively. To date, no sales of these products have occurred,
therefore, no royalty payments have been made.

In addition, the Company agreed to pay GP Strategies Corporation ("GP
Strategies"), formerly named National Patent Development Corporation, 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.

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 Product and Establishment License Applications
("PLA/ELA") to the FDA summarizing the results and observations of the drugs
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 which 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. The Company has entered
into an agreement with Abbott, pursuant to which 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. In
addition, FDA approval would have to be obtained if the Company should choose to
use an outside formulator and/or packager for ALFERON N Gel or ALFERON LDO.

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. In addition to
its United States approval, ALFERON N Injection has received regulatory approval
in Mexico, Germany, Hong Kong, and Singapore, and registration filings have been
submitted in certain other countries.

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.

Research Staff and Employees

As of April 6, 1999, the Company had approximately 54 full-time employees,
of whom 9 hold Ph.D. degrees, 1 holds an M.D. degree and 24 hold other degrees
in scientific or technical fields. Of such employees, approximately 13 were
engaged in research and product development, 17 were engaged in quality control,
regulatory and quality assurance and product and process improvement for
manufacturing, 10 were engaged in engineering and maintenance, 6 were engaged in
medical affairs and the remainder were general and administrative personnel.


Research and Development

During the fiscal years ended December 31, 1998, 1997, and 1996, the
Company expended approximately $8.9 million, $11.9 million, and $6.4 million,
respectively for research and development. Substantially all of these
expenditures were for Company-sponsored research and development programs.

Item 7. Management's Discussion and Analysis of Financial Condition and
Results of Operations

Since January 1981, the Company has been primarily engaged in the research
and development of pharmaceutical products containing Natural Alpha Interferon.
The Company has experienced significant operating losses since its inception.
Although the Company received FDA approval in October 1989 to market ALFERON N
Injection in the United States for the treatment of certain genital warts and
ALFERON N Injection currently is marketed and sold in the United States by the
Company, in Mexico by Andromaco, and in Germany by Cell Pharm, the Company has
had limited revenues from the sale of ALFERON N Injection to date. For the
Company to operate profitably, the Company must sell significantly more ALFERON
N Injection. Increased sales will depend primarily upon the expansion of
existing markets and/or successful attainment of FDA approval to market ALFERON
N Injection for additional indications. The future revenues and profitability
of, and availability of capital for, biotechnology companies may be affected by
the continuing efforts of governmental and third-party payors to contain or
reduce the costs of health care through various means. The Company has limited
financial resources with which to support future operating activities and to
satisfy its financial obligations as they become payable. Consequently,
management is continuing to actively pursue raising additional capital by either
(i) issuing securities in a private equity offering, (ii) licensing the rights
to its injectable, topical or oral formulations of alpha interferon, or (iii)
selling the Company. The Company has primarily financed its operations to date
through private placements and public offerings of the Company's securities.
This may be more difficult in the future in light of the results to date of the
Company's Phase 3 studies of ALFERON N Injection in HIV- and HCV-infected
patients. See "Business - ALFERON N Injection - Clinical Trials for New
Indications."

All per share amounts have been adjusted for a one-for-four reverse stock
split that became effective as of March 21, 1997 and for a one-for-five reverse
stock split that became effective as of January 6, 1999.

Liquidity and Capital Resources

As of April 6, 1999, the Company had an aggregate of $77,000 in cash and
cash equivalents. Until utilized, such cash and cash equivalents are being
invested principally in short-term interest-bearing investments. In addition,
the Company also had approximately $500,000 in accounts receivable generated
from sales of ALFERON N Injection which the Company expects to be collected
within the next 30 to 45 days.

The Company intends to participate in the State of New Jersey's corporation
business tax benefit certificate transfer program (the "Program"), which when
effective will allow certain high technology and biotechnology companies to
transfer unused New Jersey net operating loss carryovers to other New Jersey
corporation business taxpayers. The Company has submitted an application to the
New Jersey Economic Development Authority (the "EDA") to participate in the
Program. If the Company's application is approved, the EDA will then issue 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 will be able to transfer
its New Jersey net operating losses from the last seven years. The Company
estimates 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. Applying the maximum New Jersey corporate income
tax rate of 9% and the minimum statutory transfer price of 75%, such unused New
Jersey net operating loss carryovers would have a value of at least $5.73
million. This assumes that (i) the EDA certifies the Company's eligibility to
participate in the Program and that the Company has at least $5.73 million of
available unused New Jersey net operating loss carryovers and (ii) the Company
is able to find a purchaser for all of its available unused New Jersey net
operating loss carryovers, as to which there can be no assurance. In addition,
the administrative procedures for participation in the Program have not yet been
finalized by the EDA, and the Company is unable to predict how such procedures
may affect the amount or timing of any benefit the Company may receive from
participating in the Program.

The Company requires substantial funds to conduct research and development
and pre-clinical and clinical testing and to market its products. For the year
ended December 31, 1998, the cash utilized by the Company's operations was
approximately $14.1 million.


The Company has obtained human white blood cells used in the manufacture of
ALFERON N Injection from several sources, including the American Red Cross (the
"Red Cross") pursuant to a supply agreement dated April 1, 1997 (the "Supply
Agreement"). In addition, the Company will not need more human white blood cells
until such time as production of ALFERON N Injection is resumed, and has not
purchased any since April 1, 1998. 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 of 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% 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 (with a
market value of $1,171,875 at December 4, 1998)and additional shares at some
future date as requested by the Red Cross. 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 wold be
waived. In January 1999 the Company granted the Red Cross a 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.

As the liability to the Red Cross remains unsettled until such time as the
Red Cross sells the shares they have already received and could receive in the
future, the Company has recorded any shares issued to the Red Cross as
"Settlement Shares" within stockholders equity. Any decreases in the market
value of the Company's common stock below $1.2 million, until such time as the
Red Cross were to sell its shares, would impact the value of the shares held by
the Red Cross and accordingly require an adjustment to "Settlement Shares". Due
to the decline in the Company's stock price from November 23, 1998 to December
31, 1998, an adjustment for $525,000 has been recorded with a corresponding
charge to operations.

In an agreement dated March 25, 1999, GP Strategies Corporation ("GP
Strategies") agreed to lend the Company $500,000 at the rate of $250,000 a month
(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 to
purchase the Company's real estate, provided that the Company has terminated its
operations and the Red Cross Debt has been repaid, and (iii)a two-year right of
first refusal in the event the Company desires to sell its real estate. In
addition, the Company agreed to allow a designee of GP Strategies to attend any
meeting with the FDA with respect to approval of ALFERON N Injection for the
treatment of hepatitis C and to issue GP Strategies 500,000 shares of Common
Stock and five-year options to purchase 500,000 shares of Common Stock at a
price of $1 per share. The Company also agreed not to increase its payroll
during the term of the GP Strategies debt without the prior consent of GP
Strategies. Pursuant to the agreement, the Company has issued a note to GP
Strategies representing the GP Strategies Debt, which note matures on September
30, 1999 and bears interest, payable at maturity, at the rate of 6% per annum.
In addition, the Company has negotiated a subordination agreement with the Red
Cross pursuant to which the Red Cross has agreed that its lien on the Company's
real estate is subordinate to GP Strategies' lien.

The Company's future capital requirements will depend on many factors,
including: continued scientific progress in its drug development programs; the
magnitude of these programs; progress with pre-clinical testing and clinical
trials; the time and costs involved in obtaining regulatory approvals; the costs
involved in filing, prosecuting, and enforcing patent claims; competing
technologies and market developments; changes in its existing research
relationships; and the ability of the Company to establish collaborative
arrangements and effective commercialization activities and arrangements.

The Company anticipates that the cash that will be utilized by the
Company's operations in 1999 will be significantly less than in 1998 as a result
of the discontinuance in 1998 of manufacturing, the conclusion in 1998 of the
Company's Phase 3 studies of ALFERON N Injection in HIV- and HCV-infected
patients, and certain other cost reductions (including the layoff of 30 people)
instituted in 1998 and early 1999 by the Company. Based on the Company's
estimates of revenues, expenses, and levels of production, management believes
that the cash presently available will be sufficient to enable the Company to
continue operations through approximately May 31, 1999. However, actual results,
especially with respect to revenues, may differ materially from such estimates,
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 collaborative or other arrangements with corporate partners or from
other sources, will be available when needed or on terms acceptable to the
Company. Insufficient funds will require the Company to further delay, scale
back, or eliminate certain or all of its research and development programs or to
license third parties to commercialize products or technologies that the Company
would otherwise seek to develop itself. The Independent Auditors' Report dated
April 15, 1999 on the Company's consolidated financial statements ended December
31, 1998 notes that the Company has suffered recurring losses from operations
and has an accumulated deficit that raise substantial doubt about its ability to
continue as a going concern.

On April 13, 1999, the Company was advised by NASDAQ that the Company's
Common Stock was being delisted for failure to maintain certain listing
requirements. As a result of being delisted from NASDAQ, the Common Stock will
trade 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.


During 1998, the Company received net proceeds of approximately $2.0
million from the sale of 960,000 shares of common stock, in order to fund the
Company's working capital.

During 1997, the Company received net proceeds of approximately $16.4
million from public and private stock offerings, primarily to institutional
investors, of the Company's common stock, in order to fund the Company's working
capital.


On December 24, 1996, the Company sold in a private placement (the
"December 1996 Private Placement") 280,750 shares of Common Stock at a price of
$32.50 per share. The $9,124,375 of proceeds from such sale (less expenses of
$61,300 excluding the impact of shares of common stock and warrants issued to
the placement agent as additional compensation) were used (i) to increase the
Company's inventory of ALFERON N Injection, (ii) to fund the Company's clinical
programs, and (iii) to increase the Company's marketing and sales capabilities.

On May 2, 1996, the Company completed the sale of 400,000 shares of Common
Stock for an aggregate of $16,000,000 (the "May 1996 Offering"). Of the net
proceeds of $14,453,000 from the May 1996 Offering, the Company used an
aggregate of $3,760,012 to pay Purdue, approximately $6,000,000 for research,
product development and clinical trials of the Company's products and the
balance for working capital and general corporate purposes.

Results of Operations

Year Ended December 31, 1998 Versus Year Ended December 31,1997

For the year ended December 31, 1998 (the "1998 Period"), the Company's
revenues of $2,007,007 included $1,930,657 from the sale of ALFERON N Injection
and the balance from sales of research products and other revenues. Revenues of
$2,955,802 for the year ended December 31, 1997 (the "1997 Period") included
$2,927,585 from the sale of ALFERON N Injection and the balance from sales of
research products. Cost of goods sold and idle production costs totaled
$6,533,462 and $1,857,959 for the 1998 Period and 1997 Period, respectively.
Idle production costs in the 1998 Period primarily represented fixed production
costs, which were incurred after production of ALFERON N Injection was
discontinued in April 1998. There were no idle production costs in the 1997
Period.

In May 1997, the Company appointed Alternate Site Distributors, Inc.
("ASD"), a wholly owned subsidiary of Bergen Brunswig Corporation, the sole
United States distributor of ALFERON N Injection. Under the agreement with ASD,
the Company sold vials to ASD, which then resold them to the marketplace. As a
result, the Company recognized revenues when it sold vials to ASD, rather than
when ASD resold them to the marketplace. In June 1998, the Company replaced ASD
with Integrated Commercialization Solutions ("ICS"), another subsidiary of
Bergen Brunswig Corporation better able to handle the Company's specialty
distribution requirements. Under the new agreement, vials are not sold to ICS,
but are instead sold by the Company directly to the marketplace, under the
administration of ICS, at which time revenues are recognized by the Company. In
the 1998 Period, ASD and the Company sold to wholesalers and other customers in
the United States 17,634 vials of ALFERON N Injection, compared to 17,040 vials
sold by ASD and the Company during the 1997 Period. Notwithstanding the slight
increase in vials sold, the Company's revenues from the sale of ALFERON N
Injection decreased by $996,928, a 34.1% decline, in the 1998 Period compared to
the 1997 Period. This decrease was due primarily to (i) ASD's sales in the 1998
Period were primarily from ASD's inventory (and therefore had been accounted for
as revenues by the Company in 1997), (ii) the Company's revenues in the 1997
Period included sales to ASD for its inventory, and (iii) a decrease in foreign
sales in the 1998 Period.

In light of the results to date of the Company's Phase 3 studies of ALFERON
N Injection in HIV- and HCV-infected patients, the Company has written-down the
carrying value of its inventory of ALFERON N Injection to its estimated net
realizable value. The write-downs were the result of the Company's reassessment
of anticipated near-term needs for product to be sold or utilized in clinical
trials (within approximately a two-year period beginning January 1, 1998 and
based on historical sales levels). As a result, during the three months ended
March 31, 1998, the Company recorded an inventory write-off of $3,089,841 in
addition to the $7,254,710 inventory write-down, which was recorded at December
31, 1997. As of December 31, 1998, the Company estimates that the remaining
inventory value represents product to be sold within a one-year period.

Research and development expenses during the 1998 Period of $8,654,888
decreased by $3,209,099 from $11,863,987 for the 1997 Period, principally
because the Company has nearly concluded its Phase 3 clinical studies of ALFERON
N Injection in HIV- and HCV-infected patients. The Company received $29,375 and
$234,996, respectively, as rental income from GP Strategies for the use of a
portion of the Company's facilities, which offset research and development
expenses.

General and administrative expenses for the 1998 Period were $4,569,608 as
compared to $4,389,025 for the 1997 Period. The increase of $180,583 was
principally due to increases in payroll and other operating expenses. GP
Strategies provides certain administrative services for which the Company paid
GP Strategies $120,000 for both the 1998 and 1997 Period. In addition, for the
1997 Period, payments to GP Strategies for services provided to the Company by
GP Strategies personnel amounted to $135,000. For the 1998 Period, receipts from
GP Strategies for services provided to GP Strategies by Company personnel
amounted to $25,000.


On February 5, 1998, the Company completed the sale of 7,500 shares of
Series A Convertible Preferred Stock to an institutional investor for an
aggregate amount of $7,500,000. The $7,179,000 of net proceeds were expected to
augment the Company's working capital while awaiting the results of the two
Phase 3 clinical trials of ALFERON N Injection for the treatment of HIV-infected
and hepatitis C patients. After considering the reaction of the Company's
stockholders to the issuance and the negative impact the issuance apparently had
on the Company's market capitalization, the Board of Directors determined on
February 13, 1998 to exercise an option to repurchase the shares of Convertible
Preferred Stock for $7,894,737 (plus accrued dividends). The net loss to the
Company on the repurchase of the Preferred Stock amounted to $737,037.

Interest income for the 1998 Period was $252,528 as compared to $670,199
for the 1997 Period. The decrease of $417,671 was due to less funds available
for investment in the current period.

As a result of the foregoing, the Company incurred net losses of
$21,325,301 and $21,739,680 for the 1998 Period and 1997 Period, respectively.

Year Ended December 31, 1997 versus Year Ended December 31, 1996

For the year ended December 31, 1997, the Company's revenues of $2,955,802
included $2,927,585 from the sale of ALFERON N Injection and the balance from
sales of research products and other revenues. Revenues of $2,091,907 for the
year ended December 31, 1996 (the "1996 Period") included $1,939,595 from the
sale of ALFERON N Injection and the balance from sales of research products and
revenues resulting from the cancellation of a prior commitment to purchase
ALFERON N Injection. There were no sales to Purdue during the 1996 Period
because the Company was negotiating the reacquisition of United States and
Canadian marketing rights from Purdue and Purdue had adequate inventory from
which to make sales pending the consummation of such reacquisition, which took
place during May 1996. Cost of goods sold and excess/idle production costs
totalled $1,857,959 and $1,399,610 for the 1997 Period and 1996 Period,
respectively. In light of the results to date of the Company's Phase 3 studies
of ALFERON N Injection in HIV- and HCV-infected patients, the Company has
written-down the carrying value of its inventory of ALFERON N Injection to its
estimated net realizable value. The write-down is a result of the Company's
reassessment of anticipated near-term needs for product to be sold or utilized
in clinical trials (within approximately a two-year period based on historical
sales levels). As a result, a provision for excess inventory was established in
1997 for $7,254,710. Substantially all of the of the inventory which was sold
during the 1996 Period had previously been written-down to its then net
realizable value. Excess/idle production costs in the 1996 Period represented
current production costs in excess of the estimated net realizable value of the
inventory produced.

Research and development expenses during the 1997 Period of $11,863,987
increased by $5,463,674 from $6,400,313 for the 1996 Period, principally because
the Company continued to intensify its level of clinical research on ALFERON N
Injection. The Company received $234,996 and $258,984 during the 1997 Period and
1996 Period, respectively, as rental income from GP Strategies for the use of a
portion of the Company's facilities, which offset research and development
expenses.

General and administrative expenses for the 1997 Period were $4,389,025 as
compared to $3,404,578 (which includes non-recurring compensation expenses of
approximately $768,000) for the 1996 Period. The increase in the 1997 Period was
principally due to increases in marketing expenses of approximately $900,000
and, to a lesser extent increases in payroll and other operating expenses. GP
Strategies provides certain administrative services for which the Company paid
GP Strategies $120,000 for each of the 1997 Period and 1996 Period. In addition,
for the 1997 Period and 1996 Period, the Company reimbursed GP Strategies zero
and $195,000, respectively, for expenses paid by GP Strategies on behalf of the
Company. For the 1997 Period and 1996 Period, payments to GP Strategies for the
services provided to the Company by GP Strategies personnel amounted to $135,000
and $154,758, respectively. For the 1997 Period and 1996 Period, receipts from
GP Strategies for the services provided to GP Strategies by Company personnel
amounted to zero and $351,759, respectively.

The $3,313,705 cost of reacquisition of marketing rights from Purdue was
charged to expense in the second quarter of 1996.

Interest income for the 1997 Period was $670,199 as compared to $440,755
for the 1996 Period. The increase of $229,444 was due to more funds available
for investment in the 1997 Period.

As a result of the foregoing, the Company incurred net losses of
$21,739,680 and $11,985,544 for the 1997 Period and 1996 Period, respectively.

Recent Accounting Developments

The Financial Accounting Standards Board ("FASB") issued Accounting
Standards (SFAS 130), "Reporting Comprehensive Income", in June 1997 which
requires a statement of comprehensive income to be included in the financial
statements for fiscal years beginning after December 15, 1997. The Company has
adopted this Statement and has no other comprehensive income, therefore
comprehensive income is the same as net income (loss).

In addition, in June 1997, the FASB issued SFAS 131, "Disclosures about
Segments of an Enterprise and Related Information". SFAS 131 requires disclosure
of certain information about operating segments and about products and services,
geographic areas in which a company operates, and their major customers. As of
January 1, 1998, the Company adopted SFAS 131, however, as the Company operates
as one business segment the adoption of this Statement has minimal impact on
disclosure and has no effect on the Company's financial position or results of
operations.

In June 1998, the FASB issued Statement of Financial Accounting Standard
No. 133 (SFAS 133), "Accounting for Derivative Instruments and Hedging
Activities". This Statement establishes accounting and reporting standards for
derivatives as either assets or liabilities in the activities. It requires that
an entity recognize all derivatives as either assets or liabilities in the
statement of financial position and measure those instruments at fair value.
This Statement is effective for all fiscal quarters of fiscal years beginning
after June 15, 1999. The Company will adopt SFAS 133 by January 1, 2000. Going
forward, the Company is still evaluating its position with respect to the use of
derivative instruments.

Year 2000

Many computer systems ("IT systems") and equipment and instruments with
embedded microprocessors ("non-IT systems") were designed to only recognize the
last two digits of a calendar year. With the arrival of the Year 2000, these
systems and microprocessors may encounter operating problems due to their
inability to distinguish years after 1999 from years preceding 1999. Failure to
properly recognize such information could generate inaccurate data or cause a
system to fail, resulting in business interruption.

The Company has developed an informal plan to address Year 2000 concerns.
The first phase, which the Company has completed was to inventory the IT systems
and non-IT systems of the Company, determine which systems were not Year 2000
compliant or Year 2000 compatible, and, among any systems that were not Year
2000 compliant or Year 2000 compatible, distinguish "critical" systems from
"non-critical" systems. Based upon the results of the tests which the Company
has conducted, the Company believes that the IT systems utilized by its
accounting department and the IT systems and non-IT systems utilized in the
production of Alferon N Injection are Year 2000 compliant. The second phase,
which the Company expects to complete by July 1999, is to remediate or replace
critical IT and non-IT systems that are non-compliant or not compatible and then
test such remediated or replaced systems.

Based on current information, the Company believes the Year 2000 issue will
not have a material adverse effect on the Company, its consolidated financial
position, results of operations or cash flows. The Company believes, based on
preliminary information, that the costs to address the Company's Year 2000
issues will not be material, although there can be no assurance that this will
be the case, or that the Company will have sufficient financial resources to
remediate. There can be no assurance that the Year 2000 remediation by the
Company or third parties will be properly and timely completed, and the failure
to do so could have a material adverse effect on the Company, its business,
results of operations, and its financial condition.

The Company has not completed its assessment of the reasonably likely worst
case scenario of Non-IT Systems and/or IT Systems failures and related
consequences. However, the Company is in the process of preparing specific Year
2000 contingency plans to mitigate the potential impact of such failures. The
Company's contingency plans, which will be based in part on the assessment of
the magnitude and probability of potential risks, will primarily focus on steps
to prevent Year 2000 failures from occurring, or if they should occur, to detect
them quickly, minimize their impact and expedite their repair. Development of
the Year 2000 contingency plans is expected to be substantially complete by the
end of September 1999.

The Company's operations may also be impacted in the event third parties
with whom the Company conducts significant business experience disruptions due
to Year 2000 problems. These third parties include vendors, suppliers,
distributors, clinical researchers, contract manufacturers, research partners,
utility companies, financial institutions, and government agencies. Prior to the
end of the second quarter of 1999, the Company intends to initiate
communications with these third parties to assess their state of readiness. The
Company currently believes that the most reasonably likely worst case scenario
concerning the Year 2000 involves potential business disruption among these
third parties. The Company could be materially adversely affected if any of
these third parties experience business disruption due to a Year 2000 problem.
While the Company intends to develop contingency plans to address potential
business disruptions at these third parties, there can be no assurance that it
will be able to do so and it is unlikely that any contingency plan will be able
to fully mitigate the impact of significant business disruptions among these
third parties.

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
Company's products under development and foreign regulatory approvals for the

approvals are obtained, uncertainty of the successful commercial development of
such products; 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 products; dependence
on certain distributors to market the Company's products; potential adverse side
effects from the use of the Company's products; potential patent infringement
claims against the Company; possible inability of the Company to protect its
technology; uncertainty of pharmaceutical pricing; substantial royalty
obligations payable by the Company; 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 AUDITORS' REPORT



The Board of Directors and Stockholders
Interferon Sciences, Inc.:

We have audited the consolidated financial statements of Interferon
Sciences, Inc. and subsidiary as listed in the accompanying index. 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 audits in accordance with generally accepted auditing
standards. Those 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 financial position of Interferon
Sciences, Inc. and subsidiary at December 31, 1998 and 1997, and the results of
their operations and their cash flows for each of the years in the three-year
period ended December 31, 1998 in conformity with generally accepted accounting
principles.

The accompanying consolidated financial statements have been prepared
assuming that the Company will continue as a going concern. As discussed in Note
3 to the consolidated financial statements, the Company has suffered recurring
losses from operations and has an accumulated deficit that 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.

INTERFERON SCIENCES, INC. AND SUBSIDIARY
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Organization and Business

Interferon Sciences, Inc. (the "Company") is a biopharmaceutical company
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 is being studied
for 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, 1998, 1997 and
1996, domestic sales totaled $1,716,157, $2,613,430 and $1,809,595,
respectively, and foreign sales (primarily Germany) totaled $214,500, $314,155
and $130,000, respectively. All identifiable assets are located in the United
States. The Company also is studying ALFERON N Gel and ALFERON LDO(R), the
Company's topical and oral formulations of Natural Alpha interferon, for the
potential treatment of viral and immune system diseases. (See Note 6).

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.

Statements of cash flows -- For purposes of the statements of cash flows,
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 betterments 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:
Estimated
Class of Assets Useful Lives
--------------- ------------

Buildings and Improvements 15 to 30 years
Equipment 5 to 10 years

Intangible assets -- The Company capitalizes costs to obtain and maintain
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 capitalized cost is immediately expensed.

Revenue recognition -- Sales are recorded upon shipment of product.

Collaborative agreement research and development revenues and costs -- The
costs of performing research and development are reported when incurred.
Generally, the Company matches its collaborative research and development
revenues in the same accounting periods in which the related research costs are
incurred. However, when the revenues are exhausted, the Company has the option
to continue the research activities at its own expense.

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.
The Company's policy is to evaluate all inventory including raw materials, work-
in process, and finished goods. 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 are 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. Due to the circumstances described in Note 9, in
1998, the Company has ceased production of finished goods in inventory and
continues to hold its long-lived assets for use. In addition, as the Company's
financial and operating situation has continued to worsen (as further described
in Note 3), and after consideration of projected revenues for 1999, the Company
has determined that the carrying value of their equipment has been impaired.
Accordingly, the Company has recorded a charge for impairement of its equipment
of $803,317 in December 1998 to write down this equipment to its estimated fair
value. Management has determined, based on their best estimates and available
information, that the estimated fair value of this equipment to be that amount
which could be recovered through the sale of the equipment. Quoted market prices
are not available.

Stock option plan - Effective on January 1, 1996, the Company adopted SFAS
No. 123, Accounting for Stock-Based Compensation, which permits entities to
recognize as expense over the vesting period the fair value of all stock-based
awards on the date of grant. As permitted under SFAS No. 123, the Company
elected to continue to apply the provisions of APB Opinion No. 25 and provide
pro forma net income and pro forma earnings per share disclosures for employee
stock option grants made in 1995 and future years as if the fair-value-based
method defined in SFAS No. 123 had been applied and, accordingly, no
compensation cost has been recognized for its stock options in the financial
statements.

Reverse stock split -- As a result of a one-for-four reverse stock split
effective as of March 21, 1997, and a one-for-five reverse stock split that
became effective as of January 6, 1999, all shares and per share information
have been restated.

Loss per share -- Basic earnings 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, 1998, 1997 and 1996, the
Company's options and warrants 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 generally accepted
accounting principles 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 revenues 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 income in the period that includes the
enactment date.


Note 3. Operations and Liquidity

The Company has experienced significant operating losses since its
inception in 1980. As of December 31, 1998, the Company had an accumulated
deficit of approximately $125.2 million. For the years ended December 31, 1998,
1997 and 1996, the Company had losses from operations of approximately $20.8
million, $22.4 million and $12.4 million, respectively. Although the Company
received FDA approval in October 1989 to market ALFERON N Injection in the
United States for the treatment of certain genital warts and ALFERON N Injection
currently is marketed and sold in the United States by the Company, in Mexico by
Industria Farmaceutica Andromaco, S.A. De C.V. and in Germany by Cell Pharm GmbH
("Cell Pharm"), the Company has had limited revenues from the sale of ALFERON N
Injection to date. For the Company to operate profitably, the Company must sell
significantly more ALFERON N Injection. Increased sales will depend primarily
upon the expansion of existing markets and/or successful attainment of FDA
approval to market ALFERON N Injection for additional indications, of which
there can be no assurance. There can be no assurance that sufficient quantities
of ALFERON N Injection will be sold to allow the Company to operate profitably.

The Company has limited financial resources as of December 31, 1998 with
which to support future operating activities and to satisfy its financial
obligations as they become payable. Consequently, management is continuing to
actively pursue raising additional capital by either (i) issuing securities in a
private equity offering, (ii) licensing the rights to its injectable, topical or
oral formulations of alpha interferon, or (iii) selling the Company.
Insufficient funds will require the Company to further delay, scale back, or
eliminate certain or all of its activities or to license third parties to
commercialize products or technologies that the Company would otherwise seek to
develop itself.

Based on the Company's estimates of revenues, expenses and levels of
production, management believes that the cash presently available will be
sufficient to enable the Company to continue operations through approximately
May 31, 1999. However, actual results, especially with respect to revenues, may
differ materially from such estimates, 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 collaborative or other
arrangements with corporate partners or from other sources, will be available
when needed or on terms acceptable to the Company.

Note 4. 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. As of March 31, 1995, the Company obtained a
non-exclusive perpetual license from Hoffmann (the "Hoffmann Agreement") which
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 replaced a 1988 non-exclusive license
which, as amended, granted the Company the right to make, use, and sell in the
United States, without a potential patent infringement claim from Hoffmann,
injectable formulations of Natural Alpha Interferon for the treatment of genital
warts or patients with diseases refractory to recombinant interferon therapy.
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. 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 5. Agreements with Purdue

In 1988, the Company entered into exclusive marketing and distribution
agreements with affiliates of The Purdue Frederick Company (collectively,
"Purdue") with respect to ALFERON N Injection. The Company reacquired from
Purdue in 1993 and 1994 all marketing rights except in the United States and
Canada. In May 1996, the Company reacquired the United States and Canadian
marketing rights from Purdue for $3,313,705, which was charged to expense in
1996.

In connection with the reacquisition of United States and Canadian
marketing rights (i) Purdue agreed to provide during the first year after the
reacquisition certain distribution services to the Company with respect to
24,000 vials of ALFERON N Injection at an aggregate cost of $240,000, and (ii)
the Company purchased from Purdue all vials of ALFERON N Injection and all other
assets of Purdue used exclusively in its ALFERON N Injection business at an
aggregate cost of $206,307.

Note 6. Research and Development Agreement with Interferon Sciences
Research Partners, Ltd.

During January 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. During May 1987, the Company filed a Product License
Application with the FDA for approval to market ALFERON Gel. At a meeting with
the FDA 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 March 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"). 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 Fujimoto Diagnostics, Inc.

In 1995, the Company entered into an agreement with Fujimoto Diagnostics,
Inc. ("Fujimoto"), a pharmaceutical company located in Osaka, Japan, for the
commercialization of the Company's ALFERON N Injection and ALFERON N Gel in
Japan. In connection with the agreement, Fujimoto purchased $1,500,000 of Common
Stock at $29.00 per share (the then market price), and agreed to purchase an
additional $500,000 of Common Stock on February 6, 1996 at the then market
price. During January 1996, Fujimoto advised the Company that, to date, it had
incurred higher than anticipated development expenses, and that it had
determined that there may be greater difficulties in obtaining Japanese
regulatory approval than originally anticipated. Fujimoto therefore requested
that the Company renegotiate such investment agreement. As a result, during the
third quarter of 1996 Fujimoto purchased the additional $500,000 of Common Stock
originally scheduled for purchase on February 6, 1996 and reimbursed the Company
$133,000 for the cancellation of a prior commitment to purchase ALFERON N
Injection. The $133,000 was recorded as other revenues in 1996. In March 1997,
Fujimoto and the Company terminated the Fujimoto Agreement.

Note 8. Agreement with Cell Pharm GmbH

In 1996, the Company entered into a supply and distribution agreement (the
"Cell Pharm Agreement") with Cell Pharm. Cell Pharm, headquartered in Hanover,
Germany, is a privately owned pharmaceutical company primarily involved in the
distribution and manufacture of products for cancer treatment and other uses.
The Cell Pharm Agreement, which terminates on June 30, 2001, unless renewed,
grants Cell Pharm rights to distribute, promote, and sell ALFERON N Injection in
Germany. The Cell Pharm Agreement provides that the Company will supply Cell
Pharm with ALFERON N Injection at specified prices, and obligates Cell Pharm to
purchase specified minimum amounts in each annual period. In addition, Cell
Pharm is required to pay the Company 50% of the incremental revenue Cell Pharm
receives as a result of selling ALFERON N Injection at a price higher than a
specified price. To date, no incremental revenue has been generated. Cell Pharm
has informed the Company that it intends to market ALFERON N Injection under the
trade name Cytoferon(R), pursuant to Cell Pharm's existing regulatory approval
to market Cellferon in Germany for the treatment of hairy cell leukemia and for
the treatment of patients who develop antibodies against recombinant alpha
interferons.

Note 9. Inventories

Inventories, consisting of material, labor and overhead, are classified as
follows:


December 31,
1998 1997
--------------------

Finished goods................... $ 3,443,786 $ 3,720,000
Work in process................. 6,466,914 5,621,714
Raw materials....................... 1,143,635 1,245,649
Less reserve for excess inventory (10,344,551) (7,254,710)
------------ ------------
$ 709,784 $ 3,332,653
============ ============



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 to date of the Company's Phase 3 studies of ALFERON
N Injection in HIV- and HCV-infected patients, the Company has written-down the
carrying value of its inventory of ALFERON N Injection to its estimated net
realizable value. The write-down is a result of the Company's reassessment of
anticipated near-term needs for product to be sold or utilized in clinical
trials (within approximately a two-year period beginning January 1, 1998 and
based on historical sales levels). As a result, inventories at December 31, 1998
and 1997 reflect a reserve for excess inventory of $10,344,551 and $7,254,710,
respectively. As of December 31, 1998, the Company estimates that the remaining
inventory value represents product to be sold within a one-year period.


Note 10. Preferred Stock

On February 5, 1998, the Company completed the sale of 7,500 shares of
Series A Convertible Preferred Stock to an institutional investor for an
aggregate amount of $7,500,000. The $7,179,000 of net proceeds were expected to
augment the Company's working capital while awaiting the results of the two
Phase 3 clinical trials of ALFERON N Injection for the treatment of HIV-infected
and hepatitis C patients. After considering the reaction of the Company's
stockholders to the issuance and the negative impact the issuance apparently had
on the Company's market capitalization, the Board of Directors determined on
February 13, 1998 to exercise an option to repurchase the shares of Convertible
Preferred Stock for $7,894,737 (plus accrued dividends). The net loss to the
Company on the repurchase of the Preferred Stock amounted to $737,037.

Note 11. Income Taxes

As a result of the loss allocation rules contained in the Federal income
tax consolidated return regulations, approximately $6,009,000 of net operating
loss carry-forwards, which expire from 2001 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 operating loss carry-forwards for
periods subsequent to May 31, 1991, and through December 31, 1998 of
approximately $84,247,000 which expire from 2006 to 2013. For the year ended
December 31, 1998, the Company had a tax net operating loss of $15,901,000,
which expires in 2013.

The Company believes that the events culminating with the closing of its
Common Stock Offering on August 22, 1995 resulted 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 are limited to an annual amount of approximately
$3,230,000. In addition, the Company has approximately $73,000 of investment tax
credit carry-forwards, which expire in 1999 and 2000 and $603,000 of research
and development credit carry-forwards, which expire from 1999 to 2002 that are,
in accordance with Internal Revenue Code, Section 383, subject to the annual
limitation under Internal Revenue Code Section 382.

At January 1, 1998, the valuation allowance was $26,655,000. The increase
to the valuation allowance of $6,428,000 is due primarily to net operating
losses. The tax effects that give rise to deferred tax assets and liabilities
consist of the following as of December 31, 1998 and 1997:




Deferred tax assets 1998 1997
- ------------------- ---- ----



Net operating loss carry-forwards $ 28,644,000 $ 23,474,000
Tax credit carry-forwards 676,000 782,000
Inventory 3,517,000 2,467,000
Impairment of equipment 273,000 ---

Valuation allowance (33,083,000) (26,655,000)
------------ ------------
Net deferred tax asset after
valuation allowance $ --- $ ---
============ ============



A valuation allowance is provided when it is more likely than not that some
portion of the deferred tax asset will be realized. The Company has determined,
based on the Company's history of annual net losses, that a full valuation
allowance is appropriate.

Note 12. Common Stock, Stock Options, Warrants and Other Shares Reserved

On January 6, 1999, the Company's stockholders approved a proposal to amend
the Company's Restated Certificate of Incorporation to effect a one-for-five
reverse stock split of the Company's Common Stock. The reverse stock split
became effective as of January 6, 1999. As of January 6, 1999, there were
21,804,138 shares of Common Stock outstanding and after the stock split there
were 4,360,808 shares of Common Stock outstanding.

The par value of the Common Stock did not change as a result of the reverse
stock splits. Cash was paid in lieu of fractional shares based on the last
reported sale price of the Common Stock on the first trading date after the
stock splits.

The Company has a stock option plan (the "Plan"), which authorizes a
committee of the Board of Directors to grant options, over a 10-year period, to
purchase not more than 25,000 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 Plan options primarily are granted at the fair market value of the
common stock at the date of the grant.


At December 31, 1998, the per share weighted-average fair value of stock
options granted during 1998, 1997 and 1996 was $ 2.20, $22.05 and $17.20 on the
date of grant using the Black Scholes option-pricing model with the following
weighted-average assumptions: 1998 - expected dividend yield of 0.0%, risk-free
interest rate of 4.3%, expected volatility of 113.9% and an expected life of 5.0
years; 1997 - expected dividend yield of 0.0%, risk-free interest rate of 6.3%,
expected volatility of 85.5% and an expected life of 4.4 years; 1996 - expected
dividend yield of 0.0%, risk-free interest rate of 5.8%, expected volatility of
77.2% and an expected life of 3.3 years.

The Company applies APB Opinion No. 25 in accounting for its Plan, and
accordingly, no compensation cost has been recognized for its stock options in
the financial statements. Had the Company determined compensation cost based on
the fair value at the grant date for its stock options under SFAS No. 123, the
Company's net loss would have been increased to the pro forma amounts indicated
below:



1998 1997 1996
---- ---- ----

Net loss as reported $(21,325,301) $(21,739,680) $(11,985,544)
pro forma (21,868,534) (24,255,223) (13,251,799)

Basic and diluted
loss per share as reported $ (6.67) $ (8.15) $ (5.98)
pro forma (6.84) (9.10) (6.60)



Pro forma net loss reflects only options granted in 1998, 1997 and 1996. In
addition, compensation cost is reflected over the options vesting period.

Employee stock option activity for options under the Plan during the
periods indicated is as follows:

On October 15, 1998, the Company repriced all existing employee stock
options to have an exercise price of $1.40 (the closing market price on that
date). Accordingly, the weighted average price of options outstanding at
December 31, 1998 has been re-stated to $1.40. All other terms and conditions
remain the same with the exception of repricing the exercise price.

At December 31, 1998, the range of exercise prices and weighted-average
remaining contractual life of outstanding options was $1.40 and 3 years,
respectively.

At December 31, 1998, 1997 and 1996, the number of options exercisable was
249,434, 153,758 and 135,423, respectively, and the weighted-average exercise
price of those options was $1.40, $35.20 and $35.60, respectively.

Note 13. Pension and Investment Plans

Effective March 1, 1992, GP Strategies Corporation ("GP Strategies"),
formerly National Patent Development Corporation, adopted the 1992 401(k)
Savings Plan (the "Savings Plan"). Effective December 31, 1991, the Plan
participants became eligible to participate in GP Strategies's Savings Plan. GP
Strategies's Savings Plan was for employees who had completed one year of
service.

The Savings Plan permitted pre-tax contributions to the Savings Plan by
participants pursuant to Section 401(k) of the Internal Revenue Code of 2% to 6%
of base compensation. The Company matched 40% of the participants' eligible
contributions based on a formula set forth in the Savings Plan. On October 1,
1997, the Savings Plan was transferred into a new Savings Plan, independent from
GP Strategies, (the "New Savings Plan"). Under the New Savings Plan,
participants may contribute up to 15% of base compensation and the Company will
match up to the 6% level of the participants eligible contributions. The New
Savings Plan matched 40% in cash and 60% in the Company's common stock up to the
6% level. For 1998, the Company's contribution to the New Savings Plan was
$288,000, consisting of $116,767 in cash and $171,233 in stock. For 1997, the
Company's contribution was $126,000, consisting of $103,033 in cash and $22,967
in stock. For 1996, the cash contribution was $79,000.

Note 14. 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 will
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 employee remain in the employ of the Company at each such
installment date. Through October 1, 1998, a deferred compensation liability of
$412,344 was accrued for these employees based on the common stock market price
of October 1, 1997. On October 1, 1998, the first installment date of the Stock
Compensation Plan, the Company agreed to pay the additional compensation in cash
in place of the issuance of the Company's common stock. Accordingly, cash of
$25,947 was paid in satisfaction of the accrued liability of $412,344. The
difference of $386,397 was credited to additional paid in capital. At the
December 31, 1998, the total number of shares reserved for issuance under the
Stock Compensation Plan for the two remaining installments is 18,451.
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 15. Related Party Transactions

GP Strategies is approximately a 7% shareholder of the Company's common
stock. The Company is a party to a management agreement with GP Strategies,
pursuant to which certain legal, financial and administrative services have been
provided by employees of GP Strategies. The fee for such services in 1998, 1997
and 1996 was $120,000 annually. In addition, during such years GP Strategies
provided to the Company, at its estimated cost, certain personnel and services
which the Company used in its operations. For the years ended December 31, 1998,
1997 and 1996, such charges amounted to zero, $135,000, and $349,758,
respectively. During the year ended December 31, 1998 and 1996, respectively,
the Company provided certain services to GP Strategies at the Company's
estimated cost of $25,000 and $351,759, respectively. Such costs were included
in general and administrative expense.

The Company owns the buildings which contain its offices and laboratories
and until March 1998 leased out a portion of the buildings to GP Strategies.
Total occupancy costs for the years ended December 31, 1998, 1997 and 1996 were
approximately $1,084,000, $1,039,000 and $991,000, respectively. GP Strategies
paid to the Company as rent GP Strategies's proportionate share of such
occupancy costs (based on both square feet occupied and number of personnel),
which amounted to $29,375, $234,996 and $258,984, respectively. Such income was
included as a reduction to research and development expense.

See Note 17 for information with respect to royalty obligations to GP
Strategies.

Note 16. Supplemental Statement of Cash Flow Information

The Company paid no income taxes or interest for the three-year period
ended December 31, 1998.

During the years ended December 31, 1998, 1997 and 1996 the following
non-cash financing and investing activities occurred:

1998:

The Company issued 330,000 shares valued at $1,250,094 of common stock as
payment against negotiated settlement (see Note 17) and accounts payable.

The Company issued 3,238 shares valued at $116,897 of common stock as
compensation.

The Company issued 25,489 shares valued at $171,233 of common stock to the
Company 401(k) Plan.

1997:

The Company issued 483 shares valued at $22,967 of Common Stock to the
Company 401(k) Plan.

The Company issued 43,142 shares of Common Stock for services provided by
the underwriter of the 1997 stock offerings.

1996:
The Company issued 13,276 shares, valued at $516,524, of Common Stock as
compensation.

The Company issued 24,413 shares of Common Stock for services provided by
the underwriter of the December 24, 1996 private placement.

Note 17. Commitments

The Company has obtained human white blood cells used in the manufacture of
ALFERON N Injection from several sources, including the American Red Cross (the
"Red Cross") pursuant to a supply agreement dated April 1, 1997 (the "Supply
Agreement"). In addition, the Company will not need more human white blood cells
until such time as production of ALFERON N Injection is resumed, and has not
purchased any since April 1, 1998. 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 of 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 (with a
market value of $1,171,875 at December 4, 1998) and additional shares at some
future date as requested by the Red Cross. 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
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.

As the liability to the Red Cross remains unsettled until such time as the
Red Cross sells the shares they have already received and could receive in the
future, the Company has recorded any shares issued to the Red Cross as
"Settlement Shares" within stockholders equity. Any decreases in the market
value of the Company's common stock below $1.2 million, until such time as the
Red Cross were to sell its shares, would impact the value of the shares held by
the Red Cross and accordingly require an adjustment to "Settlement Shares". Due
to the decline in the Company's stock price from November 23, 1998 to December
31, 1998, an adjustment for $525,000 has been recorded with a corresponding
charge to operations.

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. To date, the
Company has not generated income before taxes and therefore has not paid
royalties to GP Strategies.

See Notes 4 and 6 for information relating to royalties payable to Hoffmann
and the Partnership, respectively.

In October 1989, the Company entered into a license agreement with a
non-affiliated party for co-exclusive rights to certain low dose oral
formulations of interferon. The Company will be required to pay a royalty of 10%
of net sales, as defined, of products produced and marketed by the Company that
may be developed under the license agreement. To date, no sales of these
products have occurred, therefore, no royalty payments have been made.


Note 18. Fair Value of Financial Instruments

The carrying values of financial instruments, including cash and cash
equivalents, accounts receivable and accounts payable, approximate fair market
values, because of short maturities or interest rates that approximate current
rates.

Note 19. Subsequent Events

On January 6, 1999, the Company's stockholders approved a proposal to amend
the Company's Restated Certificate of Incorporation to effect a one-for-five
reverse stock split of the Company's Common Stock (see Note 2).

The balance sheets, statements of changes in stockholders equity, earnings
per share and all footnote disclosures at December 31, 1998 and 1997 as well as
the loss per share and average outstanding shares for the years ended December
31, 1998, 1997 and 1996, have been restated to reflect the reverse splits as if
they had occurred on January 1, 1996.

In an agreement dated March 25, 1999, GP Strategies agreed to lend the
Company $500,000 at the rate of $250,000 a month (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 to purchase the Company's real
estate, provided that the Company has terminated its operations and the Red
Cross Debt has been repaid, and (iii) a two-year right of first refusal in the
event the Company desires to sell its real estate. In addition, the Company
agreed to allow a designee of GP Strategies to attend any meeting with the FDA
with respect to approval of ALFERON N Injection for the treatment hepatitis C
and to issue GP Strategies 500,000 shares of Common Stock and five-year options
to purchase 500,000 shares of Common Stock at a price of $1 per share. The
Company also agreed not to increase its payroll during the term of the GP
Strategies Debt without the prior consent of GP Strategies. Pursuant to the
agreement, the Company has issued a note to GP Strategies representing the GP
Strategies Debt, which note matures on September 30, 1999 and bears interest,
payable at maturity, at the rate of 6% per annum. In addition, the Company has
negotiated a subordination agreement with the Red Cross pursuant to which the
Red Cross has agreed that its lien on the Company's real estate is subordinate
to GP Strategies' lien.
