                                     PART I
 
ITEM 1. BUSINESS.
 
     Unimed Pharmaceuticals, Inc. (the "Company" or "Unimed") develops and
markets prescription pharmaceutical products. Currently, the Company promotes
three approved drugs and is developing others targeted for the HIV/AIDS,
endocrinology, infectious diseases and urology markets. The Company developed
and co-promotes Marinol(R), an appetite stimulant and antiemetic drug, through
the Company's specialty sales force in the U.S. primarily to AIDS-treating
physicians. Marinol is distributed in international markets through foreign
licensees. In February 1997, the Company acquired from G.D. Searle & Co., the
long-term, exclusive U.S. marketing and distribution rights for Maxaquin(R)
(lomefloxacin), a fluoroquinolone anti-infective used in the urology and
infectious disease markets. The Company markets and distributes Maxaquin through
the efforts of the Company's specialty sales force in the U.S. primarily to
urologists and AIDS-treating physicians. In July 1997, the Company acquired from
Syntex (USA), Inc. and its Mexican affiliate ("Syntex") all rights to Anadrol(R)
(oxymetholone) for the U.S., Canada and Mexico. Anadrol is an orally active
anabolic androgenic steroid used to treat various anemias. The Company began
marketing and distributing Anadrol in the first quarter of 1998. The Company is
a Delaware corporation incorporated in 1948.
 
     The Company's business strategy is to become a premier niche pharmaceutical
products development and marketing concern. With a business strategy that
focuses on licensing and developing drugs that have successfully completed human
clinical testing milestones, the Company expects to build a diversified
portfolio of products in several therapeutic areas including HIV and other
infectious diseases, endocrinology, hematology, oncology and urology. The
Company's specific goals center on effectively marketing the current product
line while rapidly developing the current product pipeline. During 1996, the
Company completed Phase II clinical development on three new drugs that were
in-licensed in 1995 described under "Product Development." In 1997, the Company
initiated Phase III clinical trials on all three of these compounds. The Company
expects completion of these clinical trials during 1998 or early 1999. The
Company filed a New Drug Application ("NDA") with the U.S. Food and Drug
Administration ("FDA") on one of these drugs in 1997.
 
     The Company is concentrating on markets in which relatively few specialized
physicians treat affected patients. The Company believes a small and specialized
salesforce will reach targeted physicians. The Company has expanded and expects
to further expand the sales and marketing organization as new products are added
and new business opportunities arise. In addition, the Company intends to work
closely with managed care providers to ensure formulary listing of its approved
drugs.
 
     The Company's products and clinical supplies are manufactured through
contractors, although certain specialized equipment is owned and maintained by
the Company. The Company believes that qualified contract manufacturers are
available to produce both currently marketed drugs and those now under
development, and expects to continue to utilize contract manufacturing in the
foreseeable future.
 
MARINOL(R) (DRONABINOL)
 
     Marinol was approved for marketing by the FDA in 1985 for treating nausea
and vomiting associated with cancer chemotherapy in patients failing to respond
adequately to conventional antiemetic drug therapy. In 1992, the FDA approved a
second indication for Marinol: treating anorexia associated with weight loss in
patients with AIDS.
 
     Marinol is currently supplied as round soft gelatin capsules containing
2.5mg, 5mg or 10mg dronabinol. During 1997, the Company began studies on
alternative dosage forms of Marinol. These studies are aimed at identifying a
dosage form that will allow quicker absorption by the body, a feature that the
Company believes would be beneficial to, among others, cancer chemotherapy
patients who are prescribed Marinol to treat nausea and vomiting. The dosage
forms currently under review include an aerosol formulation, a sublingual
formulation and a nasal gel formulation. Of these dosage forms, the one that
proves to be the most effective will then be pursued through Phase I
bioavailability studies. Subject to the Company achieving positive
 
                                        2
   3
 
results, the selected dosage form will then need to be studied as part of a
Phase II/III clinical trial, the length of which is not yet determinable.
 
     Currently, Marinol is under clinical investigation to treat nausea and
vomiting caused by anti-HIV drug regimens. In addition, Marinol is being studied
in combination with testosterone to reverse weight loss and wasting in HIV
patients.
 
Use of Marinol(R) in Cancer
 
     Marinol is a safe and effective oral antiemetic (relieving drug-induced
nausea and vomiting) based on numerous clinical studies in cancer patients
undergoing chemotherapy. The drug is believed to exert its antiemetic effects
through binding with cannabinoid receptor sites in the brain. Marinol has been
shown effective when used as a single agent or in combination with other
antiemetic therapies for mild to moderate nausea associated with cancer
chemotherapy.
 
Use of Marinol(R) in AIDS
 
     Infection from the human immunodeficiency virus (HIV) has a largely
irreversible and progressive effect on the nutritional status of the patient.
Eventually the compromised status of the patient leads to profound weight loss,
known as HIV wasting syndrome. Studies of individuals with AIDS have shown a
high correlation between weight loss and death. Treatment with Marinol can
improve caloric intake and/or stimulate appetite, resulting in clinical
improvements.
 
Potential Use of Marinol(R) in Alzheimer's Disease
 
     Alzheimer's disease is believed to afflict an estimated four million
Americans with a projected annual increase of 400,000 new cases per year. During
1996, the Company completed a pilot study exploring use of Marinol in Alzheimer
patients as an appetite stimulant. Although the pilot study was primarily
undertaken to investigate the effect of Marinol on appetite, patients were
observed to have a significant reduction in disturbed behavior compared to
patients on placebo. The disturbed behavior most commonly associated with
Alzheimer patients is believed to be due to a degenerative process in which
brain cells are lost leading to brain atrophy. This atrophy usually leads to
memory loss in early stages of the disease and can later lead to disturbances of
arousal, attention, orientation, perception and intellectual function.
 
     A series of Phase II trials were initiated in December 1996 to further
evaluate the clinical effects of Marinol doses on the behavior of patients with
Alzheimer's disease. The Company intends to pursue a Phase III program on
Alzheimer patients if the results are favorable from the Phase II studies.
 
MAXAQUIN(R) (LOMEFLOXACIN HCL)
 
     In February 1997, the Company entered into a long-term exclusive agreement
with G.D. Searle & Co. (Searle), a wholly owned subsidiary of the Monsanto
Company, for U.S. marketing and distribution rights to Maxaquin, a
fluoroquinolone anti-infective. Fluoroquinolone sales in the U.S. are in excess
of $1 billion annually. The acquisition of this product is part of the Company's
strategy to provide multiple product offerings to AIDS-treating physicians and
ultimately to establish a presence in the urology and infectious disease
therapeutic markets.
 
     The FDA approved Maxaquin in February 1992. Currently it is indicated for:
(1) lower respiratory tract infections, (2) complicated and uncomplicated
urinary tract infections, (3) preoperatively for the prevention of infection in
transrectal prostate biopsy and, (4) preoperatively for the prevention of
infection in transurethral surgical procedures. In September of 1997, the FDA
approved a supplemental NDA for the three-day use of Maxaquin to treat
uncomplicated urinary tract infections. Prior to this, Maxaquin was approved for
a 10-day regimen.
 
     Sales were initiated in the first quarter of 1997. Initial efforts focused
on markets where Maxaquin sales have been strong historically. Future
promotional efforts will center on marketing Maxaquin as one component
 
                                        3
   4
 
of a portfolio of Unimed products offered to the Company's target physician
population including urologists (see discussion on Androgel(TM) and
Andractim(TM) under "Product Development").
 
ANADROL(R) (OXYMETHOLONE)
 
     In July 1997, the Company acquired from Syntex (USA), Inc. all rights to
Anadrol (oxymetholone), an orally active anabolic androgenic steroid used to
treat various anemias, for the U.S., Canada and Mexico. The acquisition of this
product is part of the Company's strategy to provide a multiple of product
offerings to AIDS-treating physicians and ultimately to develop and market
products for pharmaceutical markets such as hematology.
 
     Anadrol is an orally active anabolic androgenic steroid, a synthetic
derivative of testosterone. Anadrol is used to treat various anemias caused by
deficient red blood cell production. Anemias that typically display this
deficiency are associated with erythropoietin deficiency or bone marrow
dysfunction. Erythropoietin deficiency is commonly associated with chronic renal
failure and drug-induced renal dysfunction. In both cases, the kidneys produce
less erythropoietin causing reduced erythrocyte (red blood cell) production. In
addition, anemia is a common complication following treatment of cancer with
chemotherapy or radiation, which can be mylelotoxic (destructive to bone
marrow). Anadrol has been found to enhance the production of urinary excretion
of erythropoietin in patients with anemia due to bone marrow failure and often
stimulates erythropoiesis (production of red blood cells in the bone marrow) in
anemia due to deficient red cell production.
 
     Patients with HIV commonly have hematologic abnormalities and almost all
have some bone marrow abnormality. Although 10-to-20% of HIV/AIDS patients are
believed to be anemic when first seen by a healthcare professional, 70-to-80%
eventually become anemic during the course of the disease. The factors that
contribute to the development of anemia in AIDS patients include the disease
itself, opportunistic infections and their treatment, treatment with
antiretroviral drugs and the effects of chronic disease. The major cause of
anemia in AIDS patients is impaired erythropoiesis.
 
     The Company initiated sales of Anadrol in February of 1998. The Company
intends to increase visibility of Anadrol by using the Company's specialty sales
force to target physician specialists such as hematologists, oncologists and
infectious disease physicians.
 
     The Company is researching the viability of further clinical studies that
may lead to additional uses for Anadrol. Among other topics, the Company is
researching Anadrol as a treatment for HIV wasting syndrome. It is generally
believed in the HIV community that anabolic steroids can help prevent and/or
reverse the wasting syndrome effect of HIV.
 
PRODUCT DEVELOPMENT
 
     The Company has three drugs under development: Nitazoxanide (formerly
referred to as "NTZ"), an antiparasitic compound being developed for the
treatment of cryptosporidial diarrhea. Androgel(TM), a transdermal gel being
developed to treat 18-60 year-old men who do not produce sufficient levels of
testosterone; and Andractim(TM), another transdermal gel being developed to
treat men over the age of 60 for the supplementation and replacement of
testosterone.
 
NITAZOXANIDE
 
     In June 1995, the Company entered into an exclusive licensing agreement
with Romark Laboratories, L.C., Tampa, Florida ("Romark"), to develop and market
oral dosage formulations of nitazoxanide for human use in the U.S., Canada,
Australia and New Zealand. The agreement provides for rights to oral and
intravenous administration for treatment of cryptosporidiosis. In addition, the
Company has marketing rights to oral uses of nitazoxanide for all indications
and is investigating other therapeutic applications of the drug.
 
     Individuals with AIDS and others with compromised immune function are at
high risk of prolonged and potentially life-threatening infections from
Cryptosporidium parvum (C. parvum) -- a food and waterborne parasite for which
there is no effective treatment. C. parvum inhabits the respiratory and
gastrointestinal tracts
                                        4
   5
 
of animals and, increasingly, humans. In 1982, according to the Centers for
Disease Control (CDC), the number of cases of C. parvum increased significantly,
which was later determined to relate to the AIDS epidemic. The parasite is
highly contagious through contact with infected humans.
 
     Symptoms of cryptosporidiosis include diarrhea, nausea, vomiting and weight
loss. Severity of symptoms varies with the degree of immunosuppression. In
healthy people, the infection is self limiting, lasting from a few days to
several weeks. Patients with AIDS are often carriers of C. parvum for months or
even years. There is no FDA approved drug to treat cryptosporidiosis.
 
     In a Phase II clinical trial in 28 patients with AIDS and cryptosporidiosis
at Cornell Medical Center, in New York City and at Kaiser Permanente Research
Center in San Francisco, patients received up to 2,000mg per day of nitazoxanide
for eight weeks. A favorable clinical response was observed in 58% of the
patients.
 
     This trial together with patients enrolled in an unrestricted, open label
compassionate use trial, culminated in the submission of an NDA in December
1997.
 
     During 1997, the AIDS Clinical Trials Group (ACTG), a clinical research
cooperative supported by the National Institute of Allergy and Infectious
Diseases, initiated a Phase III placebo controlled study of nitazoxanide to
treat AIDS patients with cryptosporidiosis. The Company participated in the
design of this study, is providing nitazoxanide to patients and is providing
certain other supportive services to ACTG.
 
     This NDA marks the first submission of a new drug application to treat the
diarrhea associated with cryptosporidiosis in AIDS patients. The Company has
been granted priority review by the FDA of this NDA, thereby ensuring a complete
review and action within six months of filing.
 
     In 1998, the Company intends initiate studies that may provide additional
indications for nitazoxanide. These studies could include researching
nitazoxanide as a possible treatment for Helicobacter pylori, a bacterium that
is the causative agent in most cases of nonerosive gastritis.
 
ANDROGEL(TM)
 
     In 1995, the Company acquired exclusive rights from Laboratoires Besins
Iscovesco S.A. ("Besins") in the U.S., Canada and Mexico to Androgel, an
androgen replacement drug. Androgel consists of a proprietary topical gel
formulation of the male hormone, testosterone, and is applied to the arms and
abdomen. Androgel is a testosterone replacement drug used by men age 18 to 60
who do not produce sufficient levels of testosterone. This deficiency is
referred to as hypogonadism. Low testosterone is associated with a variety of
adverse effects, including impotence; lack of sex drive, diminished energy,
muscle weakness and low bone mineral density.
 
     Hypogonadism can result from a number of causes, including congenital
abnormalities (e.g., Klinefelter's syndrome -- a condition in male newborns
having an extra X chromosome), disease or injuries affecting the pituitary
gland, hypothalamus or testes, and chronic illnesses (e.g., diabetes, kidney
failure, AIDS). Hypogonadism has also been implicated as a potential factor in
the etiology of HIV wasting syndrome.
 
     In March 1997, the Company began a pivotal Phase III human clinical trial
with Androgel for the treatment of testosterone deficiency in men. This study is
expected to be complete in late 1998 or early 1999. Pending positive results,
the Company intends to file an NDA with the FDA.
 
ANDRACTIM(TM)
 
     In 1995, the Company also acquired exclusive rights from Besins in the
U.S., Canada and Mexico to Andractim, a novel, patented topical gel formulation
of the male hormone, dihydrotestosterone (DHT). Andractim has demonstrated many
of the benefits of other testosterone-replacement products but does not have the
specific type of androgen linked with prostate enlargement in men 60 and older.
Testosterone levels in men may decline 30-40% beginning in their late 40s to
their early 70s. Because of this, androgen supplementation in aging men may
prove to be beneficial.
 
                                        5
   6
 
     The Company initiated a Phase II clinical trial in 1996 to evaluate the
safety and efficacy of Andractim for treating patients with HIV wasting
syndrome. This study is expected to be complete in the second quarter of 1998.
The Company has also initiated a Phase II/III study in geriatric hypogonadism
(deficient levels of testosterone due to aging, also known as andropause) during
1997. This study is expected to be complete in 1999.
 
MARKETING AND DISTRIBUTION
 
     The Company's sales force details Marinol primarily to AIDS-treating
physicians under a co-promotional agreement with Roxane Laboratories, Inc.
("Roxane"), a member of the Boehringer Ingelheim group of companies. Sales
territories are located throughout the U.S. in cities with a high incidence of
AIDS. In March 1997, the Company began to distribute Maxaquin. The Company
details Maxaquin in the urology market and to high prescribing infectious
disease physicians. In February 1998, the Company began to distribute Anadrol.
The Company expanded its sales and marketing capabilities in 1997 and will only
further expand its sales force as market conditions warrant.
 
     The Company intends to develop a portfolio of proprietary drugs to
distribute in niche markets -- therapeutic areas such as HIV/AIDS and other
infectious diseases, urology and endocrinology where fewer than 10,000
physicians manage the majority of patients. The Company believes it can obtain
new FDA approvals from the current clinical development program and that this
will result in substantial revenue growth. The Company intends to focus on U.S.
markets and to pursue partnerships and corporate alliances to market its
products abroad.
 
     Marinol is approved for use as an antiemetic in South Africa and is under
regulatory review or use as an appetite stimulant. The product is being marketed
and sold in South Africa by Pharmacare Ltd.
 
     The Company has sublicensed the right to register, market and distribute
nitazoxanide, Androgel and Andractim in Canada to BioChem Pharma Inc.
 
MANUFACTURING
 
     Manufacture of the Company's products and drugs under development is
performed on a contract basis by third parties.
 
     The NORAC Company, Inc. ("NORAC") supplies THC (tetrahydrocannabinol), the
active ingredient in Marinol, to the Company on an exclusive basis, through
December 31, 1999, subject to an automatic annual renewal thereafter. The
Company owns the principal equipment used by NORAC to manufacture THC. THC is
synthesized and purified through a complex and time-consuming process. The loss
of NORAC as a supplier could have a material adverse effect on the Company.
 
     Under the terms of the Unimed/G.D. Searle & Co. Distribution Agreement,
Searle manufactures and supplies Maxaquin to Unimed.
 
     The terms of the agreement with Syntex provide for an initial supply of
finished Anadrol tablets to be provided to the Company. Further production will
be the responsibility of the Company, which is finalizing a contract
manufacturing agreement with Oread Pharmaceutical Manufacturing, to supply the
Company with Anadrol.
 
     The Company has supply agreements with Romark for nitazoxanide, Besins for
Androgel and Andractim. Under these agreements, the Company purchases clinical
supplies, and after approval by the FDA, will purchase finished drug products in
accordance with the Company's specifications.
 
COMPETITION
 
     There are many companies, both public and private, including well-known
pharmaceutical companies, chemical companies and specialized genetic engineering
companies, developing pharmaceuticals and biotechnology compounds for human
therapeutic applications. Most of these companies have substantially greater
financial, research and development, manufacturing, marketing and human
resources than the Company, and
                                        6
   7
 
represent significant competition. Such companies may succeed in developing
products that are more effective or less costly than any developed by the
Company and may also prove to be more successful in manufacturing and marketing.
The Company does not have a significant position in the pharmaceutical market.
 
     Passage of legislation in California and Arizona legalizing the use of
marijuana for medical purposes could result in competition for Marinol since THC
is a synthetic version of the active component of marijuana. However, the
Company does not expect efforts to promote therapeutic use of marijuana will
have a significant adverse impact on Marinol sales. There are no clinical trials
establishing the safety or efficacy of marijuana for any medical use and the
potency and purity of marijuana is not assured. Moreover, the cost of Marinol is
eligible for Medicaid reimbursements, unlike marijuana, and the illegal status
of marijuana under federal law presents a barrier to many physicians prescribing
it to patients.
 
GOVERNMENT REGULATION
 
     The FDA and comparable agencies in other countries impose substantial
requirements on the introduction of therapeutic pharmaceutical products through
lengthy and detailed laboratory and clinical testing procedures and other costly
and time-consuming procedures. Satisfaction of these requirements typically
takes a number of years and varies substantially based upon the type, complexity
and novelty of the product. In general, the FDA approval process for
pharmaceuticals involves the submission of an Investigational New Drug (IND)
application following preclinical studies, clinical trials in humans to
demonstrate the safety and efficacy of the product under the protocols set forth
in the IND, and submission of preclinical and clinical data as well as other
information to the FDA in an New Drug Application. The conduct of clinical
trials requires substantial time and expense, and there is no assurance that the
results of the trials will be sufficient to support the submission or the
approval of an NDA. The failure of Unimed to receive FDA approval for its
products under development would preclude the Company from marketing and selling
newly developed products in the United States.
 
     Pharmaceutical manufacturers are subject to extensive regulation by federal
and state regulatory agencies. The Federal Food, Drug and Cosmetic Act, the
Controlled Substance Act and other federal statutes and regulations govern or
influence the testing, manufacture, safety, labeling, storage, record keeping,
approval, advertising and promotion of pharmaceutical products. Noncompliance
with applicable requirements can result in fines, recall and seizure of
products, total or partial suspension of production and governmental refusal to
approve new products or indications. The manufacture and sale of Marinol and
Anadrol is also regulated by the Drug Enforcement Agency (DEA) and by statutes
and regulations promulgated by a number of states and foreign countries.
 
PATENTS AND PROPRIETARY RIGHTS
 
     In 1991, Marinol was designated as an Orphan Drug by the FDA for use as an
appetite stimulant in patients with AIDS. Under the Orphan Drug Act of 1983, the
Company was granted seven years of marketing exclusivity for this use in the
U.S. The seven-year period began with receipt of marketing approval from the FDA
in December 1992.
 
     In February 1997, Unimed acquired from G.D. Searle & Co. long-term
exclusive U.S. marketing and distribution rights to Maxaquin, which is the
subject of a U.S. patent. Maxaquin was approved by the FDA in February 1992 for
the following indications: (1) lower respiratory tract infections, (2)
complicated and uncomplicated urinary tract infections, (3) preoperatively for
the prevention of infection in transrectal prostate biopsy and (4)
preoperatively for the prevention of infection in transurethral surgical
procedures. The Maxaquin trademark registration is valid and subsisting in the
U.S., and as part of the marketing and distribution agreement, the Company has
the exclusive right to use the trademark in the United States. Searle holds its
rights to Maxaquin under a license agreement with a third party.
 
     The Company requested and was notified by the FDA that Andractim qualifies
as an Orphan Drug for treating weight loss in AIDS patients. In addition, the
Company received proprietary protection from a U.S. patent that was issued
during the year. This patent relates to the use of Andractim in treating
geriatric hypogonadism.
                                        7
   8
 
     The Drug Price Competition and Patent Restoration Act of 1984 (commonly
known as the "Waxman-Hatch Act") provides market exclusivity for drug products
that have received FDA market approval based on an NDA that includes data from
pivotal clinical studies conducted by the applicant. In the case of the Company,
both Androgel and Andractim will be protected against competition (for a period
of three and five years, respectively) from any company that is able to obtain
approval of an abbreviated NDA (ANDA) for a generic copy of either Company
product.
 
     Nitazoxanide, when combined with a wetting agent, and optionally, a starch
derivative, in an oral composition, is the subject of certain patents held by
its licensor, Romark Laboratories, L.C. Unimed has the right to use and practice
those patents under its license agreement with Romark; however, Unimed does not
hold any nitazoxanide-related patents directly.
 
     The Company owns the Marinol, SERC, Anadrol, Androgel and Andractim
trademarks in the U.S.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS.
 
INTRODUCTION
 
     The Company develops and markets proprietary pharmaceutical products in
niche medical markets, consisting of approximately 10,000 or fewer physicians.
During 1997, sales and cash flow from Marinol and Maxaquin, as well as cash from
cash reserves, were used to fund product development programs and expand
 
                                       10
   11
 
the Company's sales and marketing infrastructure. The Company is actively
pursuing acquisition of commercial products and rights to additional
pharmaceutical products under late-stage development or already on the market.
In 1997, Unimed's net sales were $8.9 million, a 17% increase over 1996 net
sales of $7.6 million. Marinol net sales increased by 6% over 1996 due to growth
in domestic sales and a price increase in the second quarter of 1997. Maxaquin
was introduced in the second quarter of 1997 contributing $833,000 to net sales.
 
     The Company reported a net loss of $.93 per share (basic) in 1997 compared
to net income of $.18 per share (basic) in 1996 and $.10 per share (basic) in
1995. The net loss in 1997 was caused primarily by the write down of certain
assets and investments totaling $6,580,000 or $.74 per share, a 166% increase in
sales and marketing expenses, and a 57% increase in research and development
spending.
 
     In 1997, the Company used cash to support operations of $482,000 compared
to generating cash flow from operations of $3,045,000 in 1996. The Company
reported year-end cash, cash equivalents and short-term investments of
$14,787,000 compared with $20,830,000 at year-end 1996.
 
REVENUE
 
     Fiscal 1997 net sales of Marinol, marketed as a refractory antiemetic in
cancer chemotherapy and an appetite stimulant in anorexia associated with weight
loss in AIDS, increased 6% over 1996 levels, ending the year at $8,085,000. This
compares with a 27% increase in Marinol net sales growth for 1996 to $7,649,000.
Both the 1997 and 1996 Marinol net sales increase were a result of increased
unit sales and a price increase. The Company's licensee, Roxane Laboratories,
Inc. (Roxane), markets Marinol. The Company reports the royalty income it
receives from Roxane as revenues from Marinol sales. In 1996, Marinol was
approved for use as an antiemetic in South Africa and is currently under
regulatory review for use as an appetite stimulant. The antiemetic approval
resulted in launching the product in South Africa in July 1996. Marinol sales to
countries outside the United States totaled approximately $124,000 in 1997 and
$812,000 in 1996.
 
     The Company began to market Maxaquin, a fluoroquinolone antibiotic, in the
second quarter of 1997. Net sales for the year totaled $833,000.
 
     Other pharmaceutical companies in Canada and several other international
markets promote SERC for the treatment of recurrent vertigo. During 1995, Sanofi
Winthrop in Canada marketed SERC for the Company. In December 1995, Unimed
entered into an agreement with Solvay Duphar whereby Unimed licensed the rights
to proprietary "know-how" and manufacturing for the drug SERC in the U.S. As
part of the agreement, the Company received a $1.4 million payment for product
development and for Unimed's product and trademark rights to SERC in Canada,
Australia and South Africa. Royalties from SERC sales in Canada amounted to zero
in 1997 and 1996 and $1,049,000 in 1995.
 
     Total revenue for 1997 was $8,918,000, representing 17% growth over
$7,649,000 in 1996. Higher Marinol net sales, combined with Maxaquin net sales
were responsible for the increase. For the year ended December 31, 1996, and for
all prior periods presented, the Company reclassified, for financial reporting
purposes, all research and development revenues that were historically treated
as part of total revenue. These revenues are now offset against research and
development expenses in the operating expenses section of the income statement.
This change had no effect on net income. In 1996, the Company deferred the
recognition of revenue on unconditional cash payments made from corporate
partners that were to be applied to development of the Company's product
portfolio. The Company recognized the remaining portion of this deferred revenue
in 1997.
 
     Other income (net of other expenses) decreased approximately $315,000 or
20% to $1,235,000 in 1997 primarily as a result of imputed interest expense of
approximately $113,000. The Maxaquin distribution agreement includes a long and
short-term debt obligation for which interest is imputed and recorded. Interest
income decreased to $1,049,000, a $19,000 decrease from 1996 due to lower
invested cash balances. Other income in 1997 includes $300,000 of clinical
development milestone payments from a product sub-license agreement. In 1996,
other income included approximately $311,000 from the gain on a product
sub-license
 
                                       11
   12
 
and $200,000 from a gain on the sale of a trademark. Other income in 1995
included a $106,000 write off of the Company's interest in a limited
partnership.
 
COSTS AND EXPENSES
 
     Cost of sales improved by 3% from $3,087,000 in 1996 to $2,997,000 in 1997.
The lower cost of sales in 1997 was due to lower Marinol raw material costs and
Maxaquin product costs which are lower than those of Marinol. Cost of sales in
1996 was lower than the 1995 cost of sales of $3,201,000 due primarily to lower
Marinol raw material costs.
 
     Net research and development expenses increased 136% from $1,135,000 in
1996 to $2,675,000 in 1997. As mentioned earlier, the Company started three
Phase III clinical trials during 1997 as well as several smaller studies such as
the Marinol alternate dosage form studies. The Company also prepared an NDA for
nitazoxanide and submitted it to the FDA in December. Net research and
development expenses increased 84% from $618,000 in 1995 to $1,135,000 in 1996
with the completion of three human clinical studies and initiation of several
toxicology studies. For the year ended December 31, 1996, and for all prior
periods presented, the Company reclassified, for financial reporting purposes,
all research and development revenues that were historically treated as part of
total revenue. These revenues are now offset against research and development
expenses in the operating expenses section of the income statement. This change
had no effect on net income. Approximately $1,600,000 of deferred research and
development expenditures were offset against research and development expenses
in 1997. These deferred expenses would have historically been recognized as
research and development revenue.
 
     Sales and marketing expenses increased 166% from $1,272,000 in 1996 to
$3,384,000 in 1997. During 1997, the Company organized an integrated sales and
marketing infrastructure that can provide for the coordinated introduction of
new products to targeted markets. The increase can be attributed to increased
personnel and advertising expenses related to the promotion of Maxaquin. Sales
and marketing expenses increased 20% from 1995 to 1996 as the Company added a
commercial development function to distribute new products.
 
     Operating and administrative expenses increased 25% from $2,183,000 in 1996
to $2,726,000 in 1997 primarily due to increased administrative support of the
expanded sales and marketing activities and accelerated development programs,
professional expenses related to the acquisition of product rights, higher
personnel-related expenses and executive recruitment. Operating and
administrative expenses increased 3% from 1995 to 1996. Operating and
administrative expenses as a percent of net sales were 31% in 1997 and 29% in
both 1996 and 1995. Operating and administrative expenses were $2,129,000 in
1995.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     At December 31, 1997, the Company had cash and cash equivalents and
short-term investments of $14,787,000, compared with $20,830,000 at December 31,
1996. During 1997, Unimed used cash in operations of $602,000. Working capital
decreased from $18,901,000 in 1996 to $13,210,000 in 1997, primarily due to the
purchase of Maxaquin and Anadrol product rights, the purchase of equipment and
leasehold improvements and the purchase of Company Common Stock. The Company
expects to continue to increase clinical development expenditures in 1998 as it
accelerates Phase III clinical trials. The Company will also continue to expand
its sales and marketing efforts as it adds to the portfolio of products
currently promoted. In addition, the Company will require a higher investment in
working capital in order to fund accounts receivable and inventories.
 
     During 1997, the Company received approximately $847,000 from the exercise
of stock options. The Company purchased $561,000 of its own common stock,
maintaining 108,500 shares in treasury as of December 31, 1997.
 
     Inventories increased approximately $200,000 in 1997 over 1996 levels. Due
to increasing Marinol sales and production levels of THC remaining constant, THC
inventory decreased during the year. This was offset by inventory purchases
related to Maxaquin and Anadrol. Also, the Company increased the reserve for
 
                                       12
   13
 
inventory obsolescence during 1997. The Company's Marinol distributor, Roxane,
advances funds to Unimed to maintain Marinol inventories. The current liability,
due to Roxane, is relieved on a quarterly basis through the reduction of
royalties payable to the Company. The reduction in the quarter's royalty payment
primarily corresponds to the cost of Marinol inventory sold during the quarter.
 
     The Company maintains cash reserves and short-term investments to meet
anticipated working capital, capital expenditures, research and development and
other investment opportunities. The Company intends to acquire other product
licenses, which may reduce cash balances.
 
ACCOUNTING PRONOUNCEMENTS
 
     The FASB has recently issued two new accounting standards, Statement No.
130, "Reporting Comprehensive Income" and, Statement No. 131, "Disclosures about
Segments of an Enterprise and Related Information", and if adopted will be
effective for fiscal year 1998. The Company is evaluating the effect, if any, of
these new statements.
 
YEAR 2000 PROGRAM
 
     The Company will continue to conduct a comprehensive review of its computer
systems to identify the systems that could be affected by the "Year 2000" issue
and is developing an implementation plan to resolve the issue. The Company
presently believes that, with modifications to existing software and converting
to new software, the Year 2000 problem will not pose significant operational
problems for the Company's computer systems as so modified and converted.
However, if such modifications and conversions are not completed in a timely
manner, the Year 2000 problem may have a material impact on the operations of
the Company.
 
BACKLOG, SEASONALITY AND IMPACT OF INFLATION
 
     Sales orders are typically filled shortly after receipt. In general, the
Company's products experience minor seasonal fluctuations. While raw materials
included in certain products are subject to price escalation, due to a limited
number of suppliers, the complexity of manufacturing processes and regulatory
procedures, the Company does not attribute this to inflation and does not
anticipate inflation to have a significant impact on costs in the near future.

           CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS
 
     Statements in this Annual Report on Form 10-K under the captions "Business"
and "Management's Discussion and Analysis of Financial Condition and Results of
Operations," as well as oral statements that may be made by the Company or
officers, directors or employees of the Company acting on the Company's behalf,
that are not historical fact, constitute "forward-looking statements" within the
meaning of the Private Securities Litigation reform Act of 1995. Such
forward-looking statements involve known and unknown risks, uncertainties and
other factors that could cause the actual results of the Company to be
materially different from the historical results or from any results expressed
or implied by such forward-looking statements. Such factors include, among
others, the following:
 
     Uncertainty of Product Development. A substantial amount of the Company's
resources have been, and for the foreseeable future will continue to be,
dedicated to the Company's acquisition of rights to and the development of
potential products. There can be no assurance that the Company's activities will
lead to the development or commercialization of any product.
 
                                       13
   14
 
     Regulatory and Technology Uncertainty. The Company is engaged in the
biopharmaceuticals field, which is characterized by extensive research and rapid
technological change. There can be no assurance that research and discoveries by
others will not render some or all of the Company's products non-competitive or
obsolete.
 
     Dependence on Others. The Company's strategy for development and
commercialization of its products is to rely, in part, on various arrangements
with licensors, licensees, exclusive manufacturers and suppliers and others and,
therefore, is dependent upon the success of these outside parties in the
performance of their duties. There can be no assurance that the Company will be
able to negotiate acceptable arrangements or product distribution arrangements.
There can be no assurance that the Company, at all times, will be in compliance
with the material terms and conditions of all its licensing arrangements, which
could lead to periodic renegotiations of terms.
 
     Substantial Competition and Technological Change. Many companies engage in
developing pharmaceutical products for human therapeutic applications. Most of
these companies have substantially greater capital, research and development,
human resources and experience than the Company and represent significant long-
term competition for the Company. In addition, many of these competitors have a
significantly greater experience than the Company in undertaking the development
of new pharmaceutical products and in obtaining regulatory approval. Other
companies may succeed in developing products that are more effective or less
costly than any that may be developed by the Company and may also prove to be
more successful than the Company in production and marketing.
 
     Dependence on Qualified Personnel. The Company's success is highly
dependent upon its ability to attract and retain qualified administrative,
product development and technical personnel. The loss of key personnel would be
detrimental to the Company and there can be no assurance that these employees
will remain with the Company.
 
     Uncertain Availability of Health Care Reimbursement. The Company may be
materially adversely affected by the continuing efforts of government and
third-party payers to contain or reduce the cost of health care through various
means.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Stockholders and Board of Directors
Unimed Pharmaceuticals, Inc.
 
     We have audited the accompanying consolidated balance sheets of Unimed
Pharmaceuticals, Inc. and Subsidiary as of December 31, 1997 and 1996, and the
related consolidated statements of operations, stockholders' equity and cash
flows for the years ended December 31, 1997, 1996 and 1995. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these 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 financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Unimed
Pharmaceuticals, Inc. and Subsidiary as of December 31, 1997 and 1996, and the
consolidated results of operations and cash flows for the years ended December
31, 1997, 1996 and 1995, in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Unimed Pharmaceuticals, Inc. (the Company) and its subsidiary develop and
market proprietary ethical pharmaceutical products in niche medical markets.
 
     (A) PRINCIPLES OF CONSOLIDATION
 
     The consolidated financial statements include the accounts of the Company
and its subsidiary after elimination of intercompany balances and transactions.
 
     (B) TRANSLATION OF FOREIGN CURRENCY AND RELATED MATTERS
 
     The financial statements of the Company's foreign subsidiary have been
translated into U.S. dollars. Assets and liabilities of the subsidiary have been
translated using exchange rates in effect at the balance sheet date. The
statements of operations have been translated using the average rates of
exchange for the year. Adjustments resulting from the translations are
accumulated in the stockholders' equity section of the consolidated balance
sheets. Exchange gains or losses arising from the settlement of foreign currency
transactions during the year are reflected in the consolidated statements of
operations.
 
     (C) CASH AND CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS
 
     Cash and cash equivalents and short-term investments include liquid
instruments purchased with an original maturity of 90 or fewer days.
 
     The Company has investments in short-term debt securities that have been
classified under the provisions of SFAS No. 115 as held-to-maturity. The
carrying amount of the investments approximates fair market value. Accordingly,
these investments are measured at amortized cost and temporary unrealized gains
or losses are not recognized. The Company's short-term investments are intended
to apply in part to the cost of product research and development.
 
     (D) INVENTORIES
 
     Inventories are stated at the lower of cost (first-in, first-out) or
market.
 
     (E) EQUIPMENT AND LEASEHOLD IMPROVEMENTS
 
     Depreciation is provided on a straight-line basis over the estimated useful
lives of the applicable assets. Amortization of leasehold improvements is
provided on a straight-line basis over the lesser of the estimated useful lives
of improvements or the terms of the related leases. Expenditures for repairs and
maintenance are charged to operations; replacements, renewals and betterments
are capitalized. The cost and accumulated depreciation of assets retired or
otherwise disposed of are eliminated from the accounts and any gains or losses
on such dispositions are reflected in operations.
 
     (F) INCOME TAXES
 
     The consolidated financial statements reflect the application of Statement
of Financial Accounting Standards ("SFAS") No. 109 "Accounting For Income
Taxes". The Company files a consolidated federal income tax return.
 
     (G) REVENUE RECOGNITION
 
     Revenue is recognized as earned in accordance with specific terms of each
distribution, royalty and licensing agreement.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     (H) EARNINGS PER SHARE
 
     Effective December 31, 1997, the Company adopted Statement of Financial
Accounting Standards No. 128, "Earnings per Share," which establishes standards
for computing and presenting earnings per share (EPS) and applies to entities
with publicly held common stock or potential common stock. This Statement
simplifies the standards for computing earnings per share and replaces the
presentation of primary EPS with a presentation of basic EPS.
 
     Basic earnings (loss) per share was computed by dividing net income (loss)
by the weighted-average number of common shares outstanding during the year.
 
     Diluted earnings per share was computed assuming the conversion of all
options and warrants (when dilutive) as of the beginning of the year. The number
of common shares issuable assuming conversion was then added to the
weighted-average number of common shares outstanding. No effect has been given
in 1997 to options outstanding under the Company's stock option plans and
warrants issued, as their effect is anti-dilutive.
 
     (I) MANAGEMENT ESTIMATES
 
     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 liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reported period. Actual
results could differ from those estimates.
 
     (J) STOCK-BASED COMPENSATION
 
     Effective January 1, 1996, the Company adopted Statement of Financial
Accounting Standards No. 123, "Accounting for Stock-Based Compensation" (SFAS
123). As provided by SFAS 123, the Company has elected to continue to account
for its stock-based compensation programs according to the provisions of
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees". Accordingly, compensation expense has been recognized to the extent
of employee or director services rendered based on the intrinsic value of
compensatory options or shares granted under the plans. The Company has adopted
the disclosure provisions required by SFAS 123 (see "Note 9 -- Stock Options" in
Notes to Consolidated Financial Statements).
 
     (K) RECLASSIFICATIONS
 
     Certain amounts for 1996 and 1995 were reclassified to conform to the
current year presentation.
 
     (L) LONG-LIVED ASSETS
 
     Effective January 1, 1996, the Company adopted SFAS 121, "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed
Of", which requires that long-lived assets and certain identifiable intangibles
to be held and used by an entity be reviewed for impairment whenever events or
changes in circumstances indicate that the carrying amount of an asset may not
be fully recoverable. In the event that facts and circumstances indicate that
the cost of any long-lived assets may be impaired, an evaluation of
recoverability would be performed. If an evaluation were required, the estimated
future undiscounted cash flows associated with the asset would be compared to
the asset's carrying amount to determine if a writedown to market value is
required. The adoption did not have a material effect on the Company's financial
position or results of operations.

     (M) INTANGIBLE ASSETS
 
     Intangible assets consist of Maxaquin and Anadrol product rights. These
product rights are being amortized over 5 to 20 years. Amortization is provided
on a straight-line basis over the estimated useful lives of the product rights.

agreed that Puerto Rico is not part of the United States territory. Roxane
distribution of Marinol began in July 1986 in the United States. In March 1993,
Sanofi Winthrop started to distribute Marinol in Canada. The Roxane Marinol
agreement sets forth a formula for the royalties paid on net sales of Marinol on
an equal basis. The Sanofi agreement pays a royalty-based commission on net
sales of 55% to Sanofi Winthrop and 45% to Unimed. Marinol net sales were
$8,085,000 (1997), $7,649,000 (1996) and $6,031,000 (1995). As of December 31,
1997 and 1996, trade receivables included $1,537,223 and $1,557,403,
respectively, due from Roxane. Under a separate contract, Roxane has agreed to
reimburse the Company for half of the external research costs incurred in
further clinical development of Marinol. Roxane and Unimed have agreed to fund
additional Marinol clinical trials for which budgeted costs have been mutually
agreed upon. Such reimbursements shall not exceed $3 million without prior
written approval by the parties. Roxane

paid $64,328 (1997), $27,746 (1996) and $92,334 (1995) of these costs, which is
netted against research and development expenses.
 
     In November 1990, the Company entered into an inventory agreement with
Roxane, under which Roxane will advance funds at no interest to the Company for
the purpose of producing and maintaining a three-year raw material inventory of
Marinol. Roxane advances funds to the Company for the Marinol encapsulation
process as capsules are produced. Advances are offset as Roxane sells inventory.
 
     The Company has various other licensing, marketing and distribution
agreements typical to its business. See Note 4 -- "Product Development,
Licensing and Other Agreements" in Notes to Consolidated Financial Statements.

(9) STOCK OPTIONS
 
     The Company has established certain stock-based compensation plans for the
benefit of its officers, directors, employees and consultants. The plans
generally include vesting requirements from 0 to 4 years and option lives to 10
years. Options are granted with an exercise price that approximates the market
price of the Common Stock at the date of grant. For the years ended December 31,
1997 and 1996, the 1991 Stock Option Plan was the only plan that granted
options.
 
     (A) 1991 STOCK OPTION PLAN
 
     The 1991 Stock Option Plan (the Plan) was amended by the Board of Directors
in March 1996 and approved by the stockholders in May 1996. This amendment
increased to 1,800,000 the number of shares of Common Stock reserved for
issuance under the Plan, an increase of 800,000 shares of Common Stock reserved
for granting stock options to directors, officers, and key employees and
consultants of the Company and its subsidiary. Generally, options expire 10
years from the date of grant or 90 days after termination of employment.

     Had the Company elected to apply the provisions of Statement of Financial
Accounting Standards No. 123, "Accounting for Stock Based Compensation" (SFAS
123) regarding recognition of compensation expense to the extent of the
calculated fair value of stock options granted in 1996 and 1997, reported net
income and earnings per share would have been reduced as follows:

     The effects of applying SFAS 123 in the above pro forma disclosure are not
likely to represent the effects disclosed in future years because the proforma
calculations exclude stock options that were granted before 1995.
 
     For purposes of the SFAS 123 pro forma net income and earnings per share
calculation, the fair value of each option grant is estimated as of the date of
grant using the Black-Scholes option-pricing model. The
