                                     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.
("Searle"), 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 affiliated company in Mexico, Syntex S.A. de C.V.
("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 [Cryptaz(TM) (formerly referred to
as NTZ(TM))] 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
<PAGE>   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, namely, aggressive and/or resistive behavior, 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. The Company has worked closely with Searle to prepare an NDA
supplement for Maxaquin's use to treat chronic bacterial prostatitis. Filing of
this supplement is expected by late 1998.
    
 
                                        3
<PAGE>   4
 
     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 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 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: Cryptaz(TM) (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.
    
 
   
CRYPTAZ(TM) (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 Cryptaz 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 Cryptaz 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
                                        4
<PAGE>   5
 
parasite for which there is no effective treatment. C. parvum inhabits the
respiratory and gastrointestinal tracts 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 Cryptaz
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 Cryptaz 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 to initiate studies that may provide
additional indications for Cryptaz. These studies could include researching
Cryptaz 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/or
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
<PAGE>   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
Cryptaz, 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 Cryptaz, 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
<PAGE>   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 Searle 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

     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.
 
   
     Cryptaz, 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 Cryptaz-related patents directly.
    
 
   
     The Company owns the Marinol, SERC, Anadrol, Androgel and Andractim
trademarks in the U.S. Use of the Cryptaz(TM) trademark is by agreement with
Romark Laboratories, L.L.C., the owner of the trademark.

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
<PAGE>   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
<PAGE>   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
Cryptaz 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
<PAGE>   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
<PAGE>   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.

(7) DISTRIBUTION, RESEARCH, ROYALTY AND LICENSING AGREEMENTS
 
     In February 1986, the Company entered into a distribution agreement with
Roxane Laboratories, ("Roxane"), making Roxane the Company's exclusive
distributor of Marinol in the United States. The Company and Roxane subsequently
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.
 
(8) WARRANTS
 
     In March 1991, The John N. Kapoor Trust (the Trust) purchased for $1.5
million, 1.2 million shares of the Company's Common Stock and warrants to
purchase 800,000 shares of the Company's Common Stock at an exercise price of
$2.125 per share. These warrants, which would have expired March 31, 1996,
contained certain antidilution provisions for adjustment of the exercise price
and the number of warrants. In February 1996, the Trust exercised the
aforementioned warrants to purchase 800,000 shares of the Company's Common
Stock, yielding $1.7 million to the Company.
 
     In April 1992, the Company granted to LifeScience Corporation warrants to
purchase 50,000 shares of Common Stock at an exercise price of $8.375 per share,
with an expiration date of April 1, 1997. These warrants expired unexercised.
 
     In August 1995, the Company granted to Besins Iscovesco of Paris, France,
warrants to purchase 72,550 shares of Common Stock at an exercise price of $8.00
per share, with an expiration date of August 11, 2005. As of December 31, 1997,
the 72,550 share warrant had not been exercised.
 
     In February 1996, the Company granted to Sunrise Securities Corp. warrants
to purchase 140,000 shares of Common Stock at an exercise price of $7.20 per

the 140,000 share warrant had not been exercised.
 
(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:

CONFIDENTIAL PORTIONS OF THIS DOCUMENT HAVE BEEN OMITTED AND FILED SEPARATELY
WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 24B-2 PROMULGATED
UNDER THE SECURITIES EXCHANGE ACT OF 1934,AS AMENDED

                NORAC AGREEMENT FOR MANUFACTURE AND SALE OF THC

     This AGREEMENT FOR MANUFACTURE AND SALE OF THC (this "Agreement") is made
as of January 1, 1995, by and between THE NORAC COMPANY, INC., a New Jersey
corporation ("NORAC"), and UNIMED PHARMACEUTICALS, INC., a Delaware corporation
("UNIMED"), with reference to the following facts:

     WHEREAS, pursuant to an Agreement for Manufacture and Sale of THC dated
September 9, 1992 (the "Prior Contract"), UNIMED contracted with NORAC for the
manufacture by NORAC of D-9-tetrahydrocannabinol (the "product" or "THC") to
UNIMED'S specifications from the starting raw materials of olivetol and
paramenthadienol, and the sale of the completed product to UNIMED; and

     WHEREAS, the Prior Contract has been completed; and

     WHEREAS, NORAC and UNIMED wish to enter into a new contract for NORAC to
manufacture the product and sell it to UNIMED;

     NOW, THEREFORE, in consideration of the covenants herein contained and
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties agree as follows:

     1. MANUFACTURE AND SALE OF PRODUCT.  During the term of this Agreement,
NORAC agrees to manufacture and sell THC to UNIMED only, and UNIMED agrees to
purchase THC from NORAC only, all on the terms and subject to the conditions of
this Agreement.  The term of this Agreement shall commence as of January 1,
1995 and terminate on December 31, 1999; provided, however, that this Agreement
shall be automatically renewed for additional one-year periods unless either
party has given the other party hereto at least one year's prior written notice
of its intention not to renew this Agreement.

           1.1 1995 AND 1996 QUANTITIES AND PRICE.  UNIMED ordered from NORAC a
      target quantity of XXXXXXXXXXXX of product with an estimated delivery
      date of December 31, 1995.  Such order was delivered.  UNIMED also
      ordered from NORAC a target quantity of XXXXXXXXXXXX with an estimated
      delivery date of December 31, 1996, at the following purchase prices per
      kilogram of product:

           UNIMED's orders are firm and may not be cancelled unless this
      Agreement is otherwise terminated in accordance with the terms hereof.

           1.2 QUANTITIES AND PRICES AFTER 1996.  In the event that UNIMED
      fails to place an order for any of the remaining calendar years
      hereunder of the initial term (i.e., 1997, 1998 and 1999), or any
      extension thereof, for at least XXXXXXXXXXXX of product, UNIMED shall pay
      to NORAC an amount equal to the difference between XXXXXXXXXXXXXXXXX made
      by NORAC on product sold to UNIMED during the preceding calendar year). 
      In such event, NORAC shall inform UNIMED of the shortfall, and UNIMED
      shall pay such amount to NORAC not later than December 31 of such year. 
      Notwithstanding the foregoing sentence, UNIMED shall not be obligated to
      reimburse NORAC for any shortfall below XXXXXXXXXXXX if (i) the shortfall
      is due to an allotment of the Drug Enforcement Administration (the "DEA")
      for such lesser amount, and (ii) UNIMED has used its commercially
      reasonable efforts to assist NORAC and Banner (or such other packaging
      company engaged by UNIMED) in obtaining a DEA allotment of XXXXXXXXXXXX
      or more.  UNIMED acknowledges and agrees that NORAC's estimated current
      capacity for manufacture of the product is XXXXXXXXXXXXXX, and that NORAC
      may be unable to accommodate, and UNIMED shall not place, orders in
      excess of that capacity or in excess of amounts permitted under
      applicable laws and regulations (including, but not limited to, DEA
      regulations and orders).  The order for any given year shall be placed
      with NORAC by July 1 of the preceding year and the estimated delivery
      date of such order shall be no later than December 31 of the year for
      which ordered (e.g., the order for 1997 shall be placed by July 1, 1996
      and the estimated delivery date shall be December 31, 1997.)  The price
      for the product shall be the base purchase price set forth in Section 1.1
      with the adjustment provided for in Section 1.3.

           1.3 XXXXXXXXXXXXXXXXXXXXX

           1.4 PAYMENT OF PURCHASE PRICE FOR PRODUCT; REQUEST FOR RETAINS;
      ABANDONMENT OF BATCH.

                 1.4.1  PAYMENT.  UNIMED will pay to NORAC the purchase price
            for each batch of the product, as such purchase price is specified
            in or determined pursuant to Section 1, XXXXXXXXXX, such
            installments to be payable upon the occurrence of the following
            milestones for such batch:

<PAGE>   3

                 Upon the occurrence of each of milestones 1 through 5, NORAC
            shall notify UNIMED of the occurrence thereof and, except for
            the installment of the purchase price with respect to XXXXXXXXXXX
            which shall be due and payable pursuant to Section 1.4.2, the
            installment of the purchase price with respect to such milestone
            shall be due and payable within ten (10) days thereafter.  The
            XXXXXXXXXXXXXXXXX of the purchase price shall be due and payable as
            provided in Section 1.5.  The XXXXXXXXXXXXXXXXX shall be adjusted
            to reflect any difference between the installment payments made
            under this Section and the purchase price for such product.

                 1.4.2  REQUEST FOR RETAIN OF PRODUCT.  UNIMED may, within ten
            (10) days following NORAC's notification of the occurrence of
            milestone 3 described in Section 1.4.1 for each batch of the
            product, request delivery of one Retain of the product (as defined
            below) for UNIMED's analysis and approval (which approval shall not
            be unreasonably withheld), provided that UNIMED or a laboratory
            designated by UNIMED ("Licensed Laboratory") has all licenses and
            approvals required by applicable laws and regulatory authorities to
            accept delivery and analyze the product. ("Retain" for purposes of
            this Agreement shall mean a representative sample of any given
            batch of the product.) NORAC shall deliver a Retain of the product
            to UNIMED or the Licensed Laboratory designated by UNIMED within
            twenty (20) days following the date NORAC is notified of UNIMED's
            request for such Retain pursuant to this Section.  If UNIMED elects
            to analyze the product, UNIMED shall notify NORAC of its approval
            within twenty-one (21) days following the receipt by UNIMED or the
            Licensed Laboratory designated by UNIMED of the Retain;
            alternatively, UNIMED shall notify NORAC within such twenty-one
            (21) day period of its reasons for not approving the Retain.  In
            the event that UNIMED approves of the Retain, UNIMED shall deliver
            to NORAC the payment of the installment of the purchase price for
            the product with respect to milestone 3 prior to the expiration of
            the twenty-one (21) day approval period specified herein.  In the
            event that UNIMED disapproves of the Retain and NORAC agrees with
            the reasons for such disapproval, NORAC may, at its option, either
            (i) correct the deficiencies in the unfinished product identified
            by UNIMED, notify UNIMED of such correction and send a new Retain
            of the unfinished product to UNIMED or the Licensed Laboratory
            designated by UNIMED for analysis and approval by UNIMED in
            accordance with this Section (i.e., a new twenty-one (21) day
            approval period shall apply), or (ii) abandon the product pursuant
            to Section 1.4.3, in which case the provisions of Section 1.4.3
            shall apply.  In the event that UNIMED disapproves of the Retain
            and NORAC disagrees with the reasons for such disapproval, the
            dispute shall be resolved by an independent testing organization of
            recognized repute within the U.S. pharmaceutical industry agreed
            upon by the parties (which agreement shall not be unreasonably
            withheld or delayed by either 

                                      3

            party), provided that such organization has all licenses and
            approvals required by applicable laws and regulatory authorities to
            accept delivery and analyze the product.  The cost of such
            determination shall be borne by the party against whom the decision
            is made.

                 1.4.3  ABANDONMENT OF BATCH.  NORAC may abandon the
            manufacture of any batch of the product at any time prior to the
            issuance by NORAC's laboratory of a Certificate of Analysis with
            respect to such batch.  In the event of the abandonment of the
            manufacture of any batch ("Abandoned Batch"), NORAC shall
            notify UNIMED of such abandonment and, at NORAC's option, (i)
            commence the manufacture of a new batch ("Replacement Batch"); or
            (ii) return to UNIMED all installments of the purchase price for
            the Abandoned Batch received prior to the date of abandonment.  In
            the event that NORAC elects to commence the manufacture of a
            Replacement Batch following the abandonment of an Abandoned Batch,
            (a) all installments of the purchase price previously received by
            NORAC with respect to the Abandoned Batch shall be credited against
            the installments of the purchase price payable with respect to the
            Replacement Batch, and (b) UNIMED shall not be required to pay any
            installments of the purchase price for the Replacement Batch until
            the Replacement Batch reaches the same stage in the manufacturing
            process as the Abandoned Batch had reached at the time of its
            abandonment at which time UNIMED shall be required to pay any and
            all additional installments of the purchase price with respect to
            the Replacement Batch in accordance with Sections 1.4.1 and 1.5.
            NORAC may use all or any portion of an Abandoned Batch in the
            manufacture of a Replacement Batch.

           1.5 DELIVERY.  Upon the purification and distillation of the product
      (milestone 6 described in Section 1.4.1) and the issuance of a
      Certificate of Analysis by NORAC's laboratory, NORAC shall notify UNIMED
      of same and, if so requested by UNIMED within ten (10) days of such
      notification, NORAC shall send a Retain of the product to UNIMED or the
      Licensed Laboratory designated by UNIMED for analysis and approval by
      UNIMED (which approval shall not be unreasonably withheld), provided that
      UNIMED or the Licensed Laboratory designated by UNIMED, as the case may
      be, has all licenses and approvals required by applicable laws and
      regulatory authorities to accept delivery and analyze the product.  If
      UNIMED elects to analyze the product, UNIMED shall notify NORAC of its
      approval within twenty-one (21) days following the receipt of the Retain
      by UNIMED or the Licensed Laboratory designated by UNIMED; alternatively,
      UNIMED shall notify NORAC within such twenty-one (21) day period of its
      reasons for not approving the Retain.  In the event that UNIMED
      disapproves of the Retain and NORAC agrees with the reasons for such
      disapproval, NORAC may, at its option, either (i) correct the
      deficiencies in the product identified by UNIMED, notify UNIMED of such
      correction and send a new Retain of the product to UNIMED or the Licensed
      Laboratory designated by UNIMED for analysis and approval by UNIMED in

                                      4
<PAGE>   5

      accordance with this Section (i.e., a new twenty-one (21) day approval
      period shall apply), or (ii) abandon the product pursuant to Section
      1.4.3, in which case the provisions of Section 1.4.3 shall apply.  In the
      event that UNIMED disapproves of the Retain and NORAC disagrees with the
      reasons for such disapproval, the dispute shall be resolved by an
      independent testing organization of recognized repute within the U.S.
      pharmaceutical industry agreed upon by the parties (which agreement shall
      not be unreasonably withheld or delayed by either party), provided that
      such organization has all licenses and approvals required by applicable
      laws and regulatory authorities to accept delivery and analyze the
      product.  The cost of such determination shall be borne by the party
      against whom the decision is made.  The sixth installment of the purchase
      price for such batch shall be due and payable concurrently with UNIMED's
      approval; provided, however, in the event that UNIMED does not have, and
      UNIMED does not designate, a Licensed Laboratory which has all licenses
      and approvals required by applicable laws and regulatory authorities to
      accept delivery and analyze the Retain at the time of NORAC's
      notification to UNIMED of the issuance of a Certificate of
      Analysis for a batch of the product by NORAC's laboratory, the sixth
      installment of the purchase price for such batch of the product shall be
      due and payable within ten (10) days following such notification.  Upon
      receipt by NORAC of UNIMED's approval and the sixth installment of the
      purchase price for such batch, the finished product shall be placed in
      UNIMED's safe at NORAC's plant in Azusa, California (or if already in
      UNIMED's safe, shall be segregated therein).  Title to the product shall
      pass to UNIMED upon placement or segregation, as the case may be, of the
      product in UNIMED's safe following approval and payment, which act shall
      constitute delivery to UNIMED and the date of which shall be herein
      referred to as the "date of delivery."  UNIMED may remove the finished
      and paid for product from its safe at any time on or after the date of
      delivery, provided that UNIMED has all licenses and approvals required by
      applicable laws and regulatory authorities to take possession of the
      product.  Within a reasonable period following notification by NORAC that
      NORAC's reasonable storage capacity for product has been reached, UNIMED
      shall remove sufficient delivered product from NORAC's premises to allow
      NORAC to continue production and delivery of the product.  Within thirty
      (30) days following the termination of this Agreement, UNIMED shall
      remove all delivered product from NORAC's premises.

     2. COMMERCIALLY REASONABLE EFFORTS BY NORAC; DELAYS IN DELIVERY.  The
parties acknowledge and agree that the manufacture of THC is a complicated
process and that unexpected problems can arise during its production.  Such
problems can include, but are not limited to, total or partial failure of
batches, shortages in batches, inability to manufacture or deliver the product
or delays in such manufacture or delivery (whether caused by inability or delay
in obtaining approvals from the DEA or other regulatory agencies or caused by
other factors), and the inability to obtain raw materials.  NORAC will use
commercially reasonable efforts in meeting agreed production and delivery
schedules for the product as provided in this Agreement and in all construction
and manufacturing activities under this Agreement. NORAC will not be liable for
any damages of any nature or character whatsoever (including, but not 

                                      5
<PAGE>   6

limited to any increased cost of obtaining replacement product, lost
profits, and incidental and consequential damages) suffered by UNIMED by reason
of the failure of NORAC to manufacture and deliver the product in the amounts
and at the times agreed upon by the parties; provided, however, that the sole
and exclusive remedies of UNIMED shall be as provided in Section 7.3 hereof and
the remaining sentences of this Section 2, to the extent  that each is
applicable. In the event that at least two-thirds (2/3) of the full amount of
product ordered by UNIMED is not delivered within ninety (90) days (or such
longer period as UNIMED approves in writing) after the delivery date specified
for such order, there shall be refunded to UNIMED, as its sole remedy, all
installment payments made for product not delivered.  NORAC will keep UNIMED
informed of any potential delays in delivery and the parties agree to discuss
possible mutually agreeable solutions to any such problems.  UNIMED may, at its
option, elect to extend any delivery period in writing.  If such failure to
deliver at least two-thirds (2/3) of the full amount of product is due to
NORAC's material breach of its obligation to make a commercially reasonable
effort to produce and deliver the product (subject to Section 10.5), the sole
remedy (in addition to a refund on installment payments for THC not delivered
and the remedy provided by Section 7.3 below) which UNIMED shall have, in law
or in equity, is that UNIMED, at its option, may terminate this Agreement by
notification to NORAC within thirty (30) days after such ninety (90) day
period.

     3.    OBLIGATIONS OF NORAC.

           3.1 SAMPLES AND BATCH RECORDS.  During the term hereof, NORAC shall
      prepare and maintain batch records and a file sample, properly stored,
      from each batch of product manufactured.  Upon termination of this
      Agreement, NORAC shall offer such file samples to UNIMED, provided that
      NORAC shall thereafter have access to same if required for regulatory or
      other purposes required by law.

           3.2 VISITS BY UNIMED.  Subject to Section 10.16, NORAC shall permit
      UNIMED's designated representatives to visit NORAC's facility at which
      the product is manufactured from time to time for the purpose of
      determining compliance with this Agreement, provided such inspections
      shall occur after reasonable notice during regular business hours and
      each visitor shall comply with NORAC's security procedures.

           3.3 CHANGES BY NORAC.  During the term hereof, NORAC may make
      material modifications to the manufacturing equipment, or to the portion
      of its manufacturing facility at which the product is manufactured, only
      after providing written notice to UNIMED, and then only if such
      modifications are in compliance with regulations and orders of the U.S.
      Food and Drug Administration ("FDA").  NORAC may, without further
      investigation, conclusively rely on any written notice by UNIMED that any
      such modifications are in compliance with FDA regulations and orders,
      which notification by UNIMED shall not be unreasonably withheld or
      delayed by UNIMED.

                                      6

<PAGE>   7


           3.4 INSPECTIONS BY GOVERNMENT AGENCIES.  NORAC shall promptly notify
      UNIMED of any inspections by federal, state or local regulatory
      representatives of the parties of its manufacturing facility at which the
      product is manufactured and the results of any such inspections,
      including actions taken by NORAC to remedy conditions cited in such
      inspections.

           3.5 PERMITS.  NORAC shall obtain and maintain all licenses, permits
      and registrations necessary for NORAC to manufacture and supply the
      product hereunder, provided that there can be no assurances that DEA
      allotments will remain available in any specific amount that may be
      desired by Unimed; further provided, that NORAC agrees to use its
      commercially reasonable efforts to obtain such allotment in the amount
      requested by UNIMED from time to time and that UNIMED agrees to use its
      commercially reasonable efforts to assist NORAC and Banner (or such other
      packaging company engaged by UNIMED) in obtaining such allotment in the
      amount requested by UNIMED from time to time.

           3.6 ACCESS TO RECORDS.  During the term hereof and for such longer
      period as may be required by law, NORAC shall maintain, and (subject to
      Section 10.16) shall grant UNIMED reasonable access to, all books and
      records (including, but not limited to, batch records) related to the
      manufacture of the product as may be necessary to determine compliance
      with this Agreement or for such other purpose as may be required by law.

     4. NORAC'S COVENANTS AND WARRANTIES.  NORAC hereby covenants, represents
and warrants that:

           4.1 COMPLIANCE WITH NDA.  All product manufactured for UNIMED
      pursuant to this Agreement shall, upon delivery to UNIMED, meet all
      pertinent specifications in New Drug Application No. 18-651 (together
      with all amendments and supplements thereto, if any) (the "NDA"), copies
      of which specifications have been provided by UNIMED to NORAC, and any
      other specifications for the product mutually agreed upon in writing by
      NORAC and UNIMED.

           4.2 COMPLIANCE WITH LAWS.  NORAC will store all raw materials and
      will manufacture and store the product in compliance with all then
      applicable laws, rules, orders and regulations, including all then
      current Good Manufacturing Practices of the FDA.

           4.3 COMPLIANCE WITH THE ACT.  As of the time of delivery of the
      product to UNIMED, such shipment will not be, in whole or in part, (i)
      adulterated within the meaning of the federal Food, Drug and Cosmetic Act
      (the "Act"), or any applicable state law with a substantially similar
      definition of adulteration; or (ii) an article which may 

                                      7
<PAGE>   8

      not, under the provisions of Section 404 or 505 of the Act, be
      introduced into interstate commerce.

           4.4 TITLE TO THE PRODUCT.  NORAC will have good title to all product
      sold hereunder, which title shall pass to UNIMED as provided herein free
      and clear of any lien or other conflicting interest of any kind of any
      person claiming through NORAC.

           4.5 NO OTHER WARRANTIES.  Except as expressly set forth in this
      Section 4, NO OTHER WARRANTY IS EXPRESS OR IMPLIED.  NORAC SPECIFICALLY
      DISCLAIMS THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
      PARTICULAR PURPOSE.  The provisions of Sections 4.1, 4.2 and 4.3 shall
      expire, and have no further force and effect, with any respect to any
      particular batch of product upon the delivery thereof to UNIMED.

     5. UNIMED COVENANTS AND WARRANTIES.  UNIMED hereby covenants, represents
and warrants that:

           5.1 PERMITS.  UNIMED will use commercially reasonable efforts to
      maintain the NDA in effect.

           5.2 FDA.  UNIMED shall promptly notify NORAC of any additions to or
      changes in FDA or other laws, rules, orders or regulations or to the NDA
      which would affect the manufacture or storage of the product.

           5.3 NO INFRINGEMENT.  The product, when manufactured in accordance
      with the specifications set forth in the NDA, does not infringe the
      patent or other rights of any third person.

     6. USE OF EQUIPMENT; CONSTRUCTION.

           6.1 UNIMED EQUIPMENT.  UNIMED has previously provided certain
      equipment to NORAC for use by NORAC at its plant in Azusa, California in
      connection with the manufacture of the product.  UNIMED agrees that NORAC
      may continue to use such equipment, together with all equipment
      subsequently added pursuant to this Section 6 (collectively, the "UNIMED
      Equipment"), without rent or other charge, throughout the duration of
      this Agreement exclusively for the manufacture and sale of the product to
      UNIMED.  Upon termination of this Agreement, all of the UNIMED Equipment
      shall, subject to Section 6.4 hereof, be returned to UNIMED at UNIMED's
      expense.

           6.2 FURTHER WORK.  All costs, including but not limited to labor,
      supplies, equipment and building permits, incurred in connection with the
      acquisition of further 

                                      8
<PAGE>   9

      equipment, construction projects and other work, all of which must be
      expressly approved in advance in writing by UNIMED, shall be paid by
      UNIMED.  Details of costs shall be provided to UNIMED upon request.

           6.3   COSTS OF CONSTRUCTION.  Costs of work undertaken pursuant to
      Section 6.2 shall include, but not be limited to, the following:

                 6.3.1  LABOR.  All construction labor, other than normal
            maintenance, shall be reimbursed by UNIMED at three (3) times the
            direct hourly wage of each employee involved.

                 6.3.2  CONTRACTORS.  All outside contractors engaged by NORAC
            to assist in construction or other work shall be reimbursed by
            UNIMED at cost plus ten percent (10%).

                 6.3.3  MATERIALS AND EQUIPMENT.  NORAC shall be reimbursed by
            UNIMED for all materials and equipment purchased by NORAC for work
            requested or approved by UNIMED, at the identified cost therefor,
            plus ten percent (10%) to cover the cost of miscellaneous supplies
            and materials.

           6.4   NORAC'S RIGHT OF FIRST REFUSAL.  In the event that during the
      term of this Agreement UNIMED desires to sell or otherwise transfer all
      or any part of the UNIMED Equipment, UNIMED shall first offer in writing
      to sell such equipment to NORAC at the same price and on the same terms
      as offered by a bona fide purchaser offering to purchase such equipment
      (the "Offer").  Such notice to NORAC shall be accompanied by a copy of
      the Offer.  NORAC shall have ten (10) days following the date of such
      notice to elect to exercise its right of first refusal by so notifying
      UNIMED in writing and by payment for such equipment at the price and on
      the terms specified in the Offer within thirty (30) days after the
      expiration of such ten (10) day period.  If NORAC shall fail to so notify
      UNIMED within the said ten (10) day period, it shall be deemed to have
      rejected said offer.  In that event, UNIMED may sell or transfer such
      equipment to said bona fide purchaser provided that such equipment is
      sold at a price at least equal to the price stated in the Offer and in
      accordance with the other terms stated therein, and the provisions of
      this Section 6.5 shall not thereafter apply to any subsequent sales or
      other transfers of such equipment.  If, however, no such sale or transfer
      is consummated within one hundred twenty (120) days from the date of the
      original Offer, the foregoing requirement that the UNIMED first offer to
      sell such equipment to NORAC shall again apply.

      7.   DEFAULT.

           7.1 EVENT OF DEFAULT.  It shall constitute an event of default by a
      party under this Agreement if such party is in material breach of its
      duties and obligations under this Agreement (including, but not limited,
      to any failure to pay money when due) and fails to cure the same within
      thirty (30) days after written notice thereof is given by the other
      party.

           7.2 TERMINATION.  Upon the occurrence hereunder of any event of
      default by a party hereto, (which event of default has not been cured
      within the thirty (30) day period described in Section 7.1), the other
      party may, upon notice to the defaulting party, and in addition to all
      other rights and remedies available to it under this Agreement or at law
      or in equity (except as otherwise expressly provided in this Agreement),
      terminate this Agreement within a reasonable time after the occurrence of
      such event of default.

           7.3 TRANSFER OF TECHNOLOGY.

               7.3.1  WRONGFUL TERMINATION OR FAILURE TO USE COMMERCIALLY
           REASONABLE EFFORTS.  In the event that NORAC either (i)
           terminates this Agreement other than in accordance with any of the
           provisions of this Agreement, or (ii) materially breaches its
           obligation to make a commercially reasonable effort to produce and
           deliver the product pursuant to this Agreement, then NORAC shall
           immediately grant to UNIMED a perpetual, royalty free  license to
           all manufacturing know-how and technology used by NORAC to
           manufacture THC.  The foregoing license (i) shall be exclusive to
           UNIMED, with the right to grant sublicenses, with respect to the use
           of such know-how and technology to manufacture THC, and (ii) shall
           permit UNIMED and its sublicensees to use such know-how and
           technology only to manufacture THC and for no other purpose.  NORAC
           shall retain all rights to use such know-how and technology
           (including the right to grant sublicenses) for the manufacture of
           products other than THC.

               7.3.2  OTHER TERMINATION.  In the event of any termination of 
           this Agreement that occurs other than as described in clauses
           (i) or (ii) of Section 7.3.1 above, and other than by reason of a
           breach of this Agreement by UNIMED, the parties agree to discuss a
           grant by NORAC to UNIMED of a license to use all of its
           manufacturing know-how and technology used by NORAC to manufacture
           the product for UNIMED, for such consideration as the parties may
           mutually agree.

      8.   INSURANCE.

           8.1 PROPERTY AND CASUALTY INSURANCE.  UNIMED shall provide property
      insurance coverage for UNIMED'S equipment and finished product at
      NORAC'S facility in accordance with standard practice in the industry. 
      UNIMED and NORAC shall be shown as loss payees thereunder as their
      interests may appear.  NORAC shall provide adequate property insurance
      for the replacement cost of NORAC'S plant and equipment, to the extent
      utilized in the production of the product. NORAC shall be reimbursed, in
      accordance with Section 6.2 and other provisions of this Agreement, for
      any out-of-pocket or labor costs it incurs in rebuilding, repairing or
      replacing UNIMED's equipment or property used in the production of the
      product.

           8.2 LIABILITY INSURANCE OF UNIMED.  UNIMED shall procure and
      maintain in effect at all times during and after the term of this
      Agreement, at UNIMED's sole cost and expense, a commercial general
      liability policy of insurance in the minimum amount of $1,000,000,
      combined single limit, and a products liability policy of insurance in
      the minimum amount of $3,000,000, combined singly limit, insuring against
      personal injury and property damage caused by storage after delivery,
      distribution, sale, or use of the product, and contractual liability.
      Each of such insurance policies shall (i) either be written on a claims
      made or occurrence basis, at UNIMED's option; (ii) be obtained from an
      insurer reasonably acceptable to NORAC; (iii) name NORAC as an additional
      insured; (iv) contain a waiver of subrogation clause; (v) contain a
      cross-liability endorsement or severability of interest clause in favor

      it is primary and not contributing with any other insurance maintained by
      NORAC; and (ix) require that NORAC be given at least thirty (30) days'
      prior written notice of the modification, cancellation or expiration
      thereof.  Concurrently with its execution of this Agreement, UNIMED shall
      deliver to NORAC a certificate of insurance evidencing such insurance
      policy and a copy of such insurance policy.  The provisions of this
      Section 8.2 shall survive the expiration or termination of this
      Agreement.

           8.3 LIABILITY INSURANCE OF NORAC.  NORAC shall procure and maintain
      in effect at all times during the term of this Agreement and for a period
      of one (1) year thereafter, at NORAC's sole cost and expense, a
      commercial general liability policy of insurance in the amount of
      $1,000,000, combined single limit, insuring against personal injury and
      property damage caused by the manufacture of the product and storage
      thereof prior to delivery.  NORAC shall not be obligated to approve or
      maintain products liability insurance coverage.  The commercial general
      liability insurance policy required to be maintained by NORAC hereunder
      shall (i) be written on a claims made or 

                                     11
<PAGE>   12

      occurrence based policy, at NORAC's option; (ii) be obtained from an
      insurer reasonably acceptable to UNIMED; (iii) name UNIMED as an
      additional insured; (iv) contain a waiver of subrogation clause; (v)
      contain a cross-liability endorsement or severability of interest clause

      insured; (vi) be reasonably satisfactory to UNIMED in form and content;
      (vii) state that it is primary and not contributing with any other
      insurance maintained by UNIMED; and (vii) require that UNIMED be given at
      least thirty (30) days' prior written notice of the modification,
      cancellation or expiration thereof. Concurrently with its execution of
      this Agreement, NORAC shall deliver to UNIMED a certificate of insurance
      evidencing such insurance policy and a copy of such insurance policy.

           8.4 WORKERS' COMPENSATION OF NORAC.  NORAC shall procure and
      maintain in effect at all times during the term hereof workers'
      compensation insurance policy, including employer's liability coverage in
      accordance with applicable laws.

     9.    INDEMNIFICATION.

           9.1 INDEMNIFICATION BY UNIMED.  UNIMED agrees to indemnify and
      defend NORAC and hold it harmless from and against any and all claims,
      damage, liability, loss, cost or deficiency (including, but not limited
      to, reasonable attorneys' fees and other costs and expenses incident to
      any suit, action, proceeding, inquiry or investigation or the defense of
      any claim or for enforcing this indemnification provision) and to pay
      NORAC on demand the full amount of any expenses, claims, liabilities or
      other sums which NORAC pays or becomes obligated to pay on account of,
      arising from or related to the storage after delivery, distribution, sale
      or use of the product hereunder, including but not limited to breach of
      warranty, strict liability or product liability claims (except to the
      extent that NORAC is obligated with respect to such claims under Section
      9.2).  The provisions of this Section 9.1 shall survive the termination
      of this Agreement.

           9.2   LIMITATION OF LIABILITY OF NORAC; INDEMNIFICATION BY NORAC.

                 9.2.1 LIMITATION OF LIABILITY OF NORAC.  UNIMED acknowledges
            and agrees that notwithstanding any other provisions of this
            Agreement, NORAC's liability hereunder and to third parties shall
            be limited to claims, damages, losses, liabilities, costs or
            deficiencies (including, but not limited to reasonable attorneys'
            fees), arising from or related to the manufacture of the product or
            storage thereof prior to delivery solely to the extent that the
            injuries or damages giving rise to such claims occur and are
            actually known by NORAC during the period of manufacture of the
            product and storage thereof prior to delivery and shall exclude any
            and all products liability claims; provided, however, that this
            Section 9.2.1 shall not be construed to negate or supersede
            UNIMED's remedies set forth in 

                                     12
<PAGE>   13

            Sections 2 and 7.3 hereof under certain circumstances
            specifically set forth therein.  Nothing in this Section is
            intended to affect any other limitations on the liability of NORAC
            under any other provision of this Agreement or otherwise.  The
            limitation on NORAC's liability hereunder is a material
            consideration for NORAC entering into this Agreement, it being the
            understanding of the parties that UNIMED is providing NORAC with
            the specifications for the manufacture of the product and the
            approval of the product by UNIMED pursuant to Section 1.5 shall
            constitute UNIMED's agreement and approval that the product
            conforms to such specifications and the full and complete release
            of NORAC and its directors, officers, employees, agents and
            shareholders with respect to any and all claims, damages, losses,
            costs or deficiencies, known and unknown, arising from or relating
            to the manufacture or storage of the product.

                 9.2.2 INDEMNIFICATION BY NORAC.  NORAC agrees to indemnify and
            defend UNIMED and hold it harmless from and against any and all
            claims, damage, liability, loss, cost or deficiency (including, but
            not limited to, reasonable attorneys' fees and other costs and
            expenses incident to any suit, action, proceeding, inquiry or
            investigation or the defense of any claim or for enforcing this
            indemnification provision) and to pay UNIMED on demand the full
            amount of any expenses, claims, liabilities or other sums which
            UNIMED pays or becomes obligated to pay on account of, arising from
            or related to the manufacture of the product or storage thereof
            prior to delivery solely to the extent that the injuries or damages
            giving rise to such claims occur and are actually known by NORAC
            during the period of manufacture of the product or storage thereof
            prior to delivery (except to the extent that such claims arise from
            UNIMED's gross negligence or willful misconduct).  In no event
            shall NORAC's indemnification obligations hereunder apply to any
            products liability claims.

                 9.2.3  SURVIVAL.  The provisions of this Section 9.2 shall
            survive the termination of this Agreement.

     10. MISCELLANEOUS.

           10.1 WAIVER, AMENDMENTS AND MODIFICATIONS.  Any of the terms or
      conditions of this Agreement may be waived at any time by the party which
      is entitled to the benefit thereof only by a writing executed by the
      waiving party.  This Agreement may be amended or modified at any time, in
      whole or in part, only by a writing executed by the respective parties.
      The provisions of this Section 10 shall survive the termination of this
      Agreement.

           10.2 NOTICES.  All notices, requests and other communications
      required or permitted hereunder shall be in writing, addressed to the
      respective parties as follows:

      Any notice or other communication sent by registered or certified mail,
      return receipt requested, shall be effective on the date of receipt or
      refusal of delivery by the addressee, as specified on the return receipt
      therefor.  Notice given in any other manner shall be effective upon

          10.3  ASSIGNMENT.

                10.3.1  This Agreement shall not be assignable by either party 
          without the prior written consent of the other.  Notwithstanding the
          foregoing, NORAC may, upon UNIMED's prior written consent which
          shall not be unreasonably withheld, assign this Agreement and
          delegate its performance hereunder to a wholly-owned subsidiary of
          NORAC, and thereupon NORAC shall have no further obligations under
          this Agreement, except in the event of the breach by such subsidiary
          of any of its obligations under Section 1.4 to deliver to UNIMED any
          batch of product and the failure by such subsidiary to return to
          UNIMED any and all installments of the purchase price for such batch
          previously paid by UNIMED pursuant to Section 1.4, NORAC shall be
          obligated to return any  such installments to UNIMED and NORAC shall
          have no further obligations under this Agreement.

                10.3.2  Notwithstanding the foregoing Section 10.3.1, either 
          party may assign its rights and obligations hereunder to a
          successor by merger or to a purchaser of all or substantially all of
          its business to which this Agreement relates (provided, however, that
          this section shall not affect the provisions set forth in Section
          10.4 or the subsections thereof or the protections to UNIMED
          described therein).

          10.4 UNIMED'S RIGHT OF FIRST REFUSAL.  NORAC and its shareholders,
      as an inducement to UNIMED to enter into this Agreement, agree as
      follows:



                                     14

<PAGE>   15

                  10.4.1  The shareholders of NORAC agree that during the term
            of this Agreement they shall not sell or otherwise transfer a
            controlling interest in NORAC (as "control" is defined in Section
            10.4.5) to a direct competitor of UNIMED (as such term is defined
            in Section 10.4.5), other than in accordance with this Section
            10.4.

                  10.4.2  NORAC agrees that during the term of this Agreement it
            shall not sell or otherwise transfer that portion of its
            manufacturing facility in Azusa, California at which the product is
            manufactured (such portion of the manufacturing facility being
            herein referred to as the "Plant") other than in accordance with
            the provisions of this Section 10.4.  Notwithstanding the
            foregoing:

                       (i)  A sale or other transfer of the Plant to any person
                  or entity which controls, is controlled by or is under common
                  control with NORAC (as "control" is defined in Section
                  10.4.5) (such person or entity being herein referred to as a
                  "Control Person") shall not be subject to the provisions of
                  this Section 10.4; provided, however, any further sale or
                  other transfer of the Plant (except to another Control
                  Person) shall continue to be subject to the provisions of
                  this Section 10.4.

                       (ii) The foregoing provisions of this Section 10.4.2
                  shall not apply to any sale or other transfer of all or
                  substantially all of NORAC's manufacturing facility in Azusa,
                  California, of which the Plant is a portion; provided,
                  however, that it shall be a condition of such sale or other
                  transfer that any purchaser or other transferee shall assume
                  the obligations of NORAC under this Agreement.

                  10.4.3  If NORAC or its shareholders, as the case may be
            ("Offeror"), desire to sell or otherwise transfer a Subject
            Interest (as defined in Section 10.4.5), as provided in Sections
            10.4.1 or 10.4.2, the Offeror shall first offer in writing to sell
            the Subject Interest to UNIMED at the same price and on the same
            terms as offered by a bona fide purchaser offering to purchase the
            Subject Interest (the "Offer").  Such notice to UNIMED shall be
            accompanied by a copy of the Offer.  UNIMED shall have ten (10)
            days following the date of such notice to elect to exercise its
            right of first refusal by so notifying the Offeror in writing and
            by payment for such Subject Interest at the price and on the terms
            specified in the Offer within thirty (30) days after the expiration
            of such ten (10) day period.

                  10.4.4  If UNIMED shall fail to so notify the Offeror within
            the said ten (10) day period, it shall be deemed to have rejected
            said offer.  In that event, the Offeror may sell or transfer the
            Subject Interest to said bona fide purchaser 

                                     15

<PAGE>   16

            provided that the Subject Interest is sold at a price at least
            equal to the price stated in the Offer and in accordance with the
            other terms stated therein, and the provisions of this Section 10.4
            shall not thereafter apply to any subsequent sales or other
            transfers of any Subject Interest.  If, however, no such sale or
            transfer is consummated within one hundred twenty (120) days from
            the date of the original Offer, the foregoing requirement that the
            Offeror first offer to sell the Subject Interest to UNIMED shall
            again apply.

                 10.4.5  As used in this Section 10.4, the following terms
            shall have the meanings specified in this Section 10.4.5:

                       "Control" shall mean having the power to direct or cause
                  direction of the management and policies of NORAC.

                       A "direct competitor of UNIMED" shall mean an entity
                  that sells a pharmaceutical product which directly competes
                  with Marinol.

                       "Subject Interest" shall mean either a controlling
                  interest in NORAC (provided that it is sold or otherwise
                  transferred to a direct competitor of UNIMED) or the Plant.

            10.5 FORCE MAJEURE.

                 10.5.1  No party shall be liable for any failure to perform
            its obligations hereunder where such failure results from causes
            beyond the reasonable control of such party, including, without
            limitation, strikes, lockouts, labor disputes, embargoes, acts of
            God, inability to obtain labor or materials, governmental
            restrictions, governmental regulations, governmental orders,
            judicial orders, enemy or hostile governmental action, civil
            commotion, earthquake, fire or other casualty, provided that the
            party claiming the force majeure has given prompt notice thereof
            to the other party.  Performance by the party claiming the force
            majeure shall be suspended for the duration of the force majeure,
            subject to Section 10.5.2 below.

                 10.5.2  Notwithstanding the foregoing, in the event the
            claimed force majeure prevents NORAC from commencing manufacture of
            the product within six (6) months from the occurrence of the event
            of force majeure, either party may terminate this Agreement and
            cancel all orders for product hereunder not yet delivered
            immediately upon written notice to the other.  Upon notice of such
            termination and cancellation, NORAC shall immediately refund to
            UNIMED any and all amounts paid by UNIMED hereunder for product not
            yet delivered.  NORAC will, if requested, assist UNIMED in finding
            alternative sources of supply for the product.


                                     16

           10.6 PARTIES.  This Agreement shall be binding upon and inure to the
      benefit of the parties hereto and their respective successors and
      permitted assigns.  Nothing in this Agreement, expressed or implied, is
      intended to confer upon any person, other than the parties hereto and
      their successors and permitted assigns, any rights or remedies under or
      by reason of this Agreement.

           10.7 ARBITRATION.  Any controversy or claim arising out of or
      relating to this Agreement, or the breach or interpretation thereof,
      shall be resolved by binding arbitration in Los Angeles County,
      California.  The arbitrator, who shall be a retired judge of the Superior
      Court, shall be selected jointly by the parties, or if the parties fail
      to do so, shall be appointed by Judicial Arbitration and Mediation
      Services, Inc.  The arbitration shall be conducted in accordance with the
      provisions of Part 3, Title 9 (Section 1280 et seq.) of the California
      Code of Civil Procedure.  The provisions of Section 1283.05 of the
      California Code of Civil Procedure, which provides for certain discovery
      procedures, is by this reference made a part hereof.  A judgment upon the
      award rendered in the arbitration may be entered in any court having
      jurisdiction thereof.  Neither the provisions of this Section nor the
      exercise of any rights hereunder shall limit the right of any party to
      institute and maintain litigation in order to obtain, at any time,
      provisional or ancillary remedies including, without limitation,
      attachment and injunctive relief; the institution and maintenance of such
      litigation shall not constitute a waiver of the right of any party to
      submit any controversy or claim to arbitration as herein provided.  In
      any action or arbitration proceeding brought under or arising out of or
      relating to this Agreement, or the breach or interpretation thereof, each
      party hereby consents to the jurisdiction of any competent court within
      the State of California and to service of process by any means authorized
      by California law.

           10.8 ATTORNEYS' FEES.  If any proceeding (including any arbitration
      proceeding) is brought for the enforcement of this Agreement, or because
      of an alleged dispute, breach, default or misrepresentation in connection
      with the provisions hereof, the successful or prevailing party in such
      proceeding shall be entitled to recover its reasonable attorneys' fees
      and other costs incurred in such proceeding.

           10.9 LATE PAYMENT.  If any amount is not paid when due under this
      Agreement, interest shall thereafter accrue on such amount at a rate of
      three percentage points (3%) in excess of the "prime rate" as reported in
      The Wall Street Journal (or if more than one prime rate is reported, the
      highest thereof) until such payment is received by the party to whom such
      payment is owed (the "payee"), and, in addition, in the event that the
      person obligated to make such payment (the "payor") fails to make payment
      to the payee within twenty-one (21) days following the delivery to the
      payee of written notice of non-payment, the payee shall be entitled to
      receive a late charge in an amount equal to ten percent (10%) of the
      overdue amount. The parties recognize that a default in making payments
      as provided herein will require the payee to incur additional costs and
      expenses 

                                     17
<PAGE>   18

      and that the damages caused thereby would be extremely difficult
      and impractical to ascertain.  The parties agree that an amount equal to
      the late charge plus the accrual of interest at the prime rate plus 3% is
      a reasonable estimate as of the date hereof of the damage to the payee in
      the event of late payment.

           10.10 COUNTERPARTS.  This Agreement may be executed in any number of
      counterparts, each of which shall be deemed an original, but all of which
      taken together shall constitute only one instrument.

           10.11 INTERPRETATION.  The section headings of this Agreement are
      for the convenience of reference only and shall not be deemed to alter or
      affect the meaning of any provision hereof.  This Agreement has been
      reviewed by both parties and their respective counsel, and as a result,
      shall be given a fair and reasonable interpretation without consideration
      or weight being given to its having been drafted by any one party or its
      counsel.

           10.12 ENTIRE AGREEMENT.  This Agreement hereto constitutes the
      final, complete and exclusive agreement between the parties and
      supersedes any and all prior negotiations, discussions, understandings
      and agreements between the parties relating to the subject matter hereof
      (including, but not limited to the Prior Contract).

           10.13 TIME OF ESSENCE.  Time is of the essence in the observation
      and performance of the provisions of this Agreement.

           10.14 SEVERABILITY.  In case one or more of the provisions contained
      in this Agreement shall be invalid, illegal or unenforceable in any
      respect, the validity, legality and enforceability of the remaining
      provisions contained herein shall not in any way be affected or impaired
      hereby.

           10.15 GOVERNING LAW.  This Agreement shall be construed and enforced
      in accordance with and governed by the laws of the State of California,
      without regard to principles of conflicts of laws.

           10.16 CONFIDENTIALITY.  The parties agrees that all information
      obtained by them pursuant to Sections 3.2 or 3.6 or otherwise shall
      remain strictly confidential and shall not be used or disclosed by either
      party for any purpose other than to determine compliance with this
      Agreement or for such other purpose as may be required by law.  In the
      event that disclosure is required by law, the recipient will be advised
      of the confidential nature of such information and a confidentiality
      agreement or protective order maintaining the confidentiality of such
      information will be obtained to the maximum extent possible.

after receipt of such Product and, if not so made, shall be irrevocably waived
by Distributor.  If Company disputes Distributor's rejection (for alleged
Product quality reasons) made as provided above of all or part of any shipment
of finished Product such dispute shall be resolved by an independent testing
organization or consultant, or recognized repute within the pharmaceutical
industry in the Territory mutually agreed upon by the parties, the appointment
of which shall not be unreasonably withheld or delayed by either party.  The
determination of such entity with respect to the rejection of all or part of
any shipment of finished Product shall be final and binding upon the parties,
but only as to the reasons given by Distributor in rejecting the shipment and
shall have no effect on any matter for which said entity did not render a
determination.  The cost of such determination shall be borne by the party
against whom the decision is made.

     (d) Except as provided in subparagraph (e) below, Distributor shall
indemnify and hold Company, its subsidiaries and affiliates and their
respective directors, officers, employees and agents harmless against all
claims, suits, demands, judgments or damages, including reasonable attorneys'
fees and court costs, arising out of or relating to Distributors (i) breach of
this Agreement, or (ii) handling, sale or promotion of the Product in the
Territory (including, without limitation any strict liability, product
liability, tort or similar claim).

     (e) Company will indemnify and hold Distributor, its subsidiaries and
affiliates and their respective directors, officers, employees and agents
harmless against all claims, suits, demands, judgments or damages, including,
reasonable attorneys' fees and court costs, arising out of or relating to
Company's (i) breach of this Agreement or (ii) failure to supply Product
complying with any of the express Product quality requirements of this
Agreement or (iii) third party claims resulting from Product sold prior to the
Effective Date.

     (f) Notwithstanding the foregoing or any other provision of this
Agreement, neither party shall be liable to the other for lost profits or
consequential damages of any kind.

     10. DURATION AND TERMINATION AND REMEDIES.

     (a) Subject to paragraphs (b) and (c) below, this Agreement shall be in
effect for the period from the Effective Date and until twenty (20) years after
such date.

     (b) This Agreement may be terminated, effective immediately, by a party
("Injured Party") at any time upon written notice to the other party after:

           (i)   the failure of the other party to comply with then Agreement in
      respect of any obligation other than an obligation to make any payment
      hereunder, which failure is not cured within thirty (30) days of written
      notice thereof;

           (ii)  the suspension, liquidation, dissolution or bulk sale, or
      notice thereof, of the other party's business without the prior written
      consent of the Injured Party or in the event of the calling of a meeting
      of such party's creditors, an assignment by such other party for the
      benefit of creditors, the insolvency of any kind of such other party, or
      the filing of any attachment, distraint, levy, execution or judgment
      against such party, any filing of a voluntary or involuntary petition
      under the provisions of any bankruptcy act, or any application for or
      appointment of a receiver for the property of such other party;

           (iii) the cessation by such other party of its business; or

           (iv)  the other party fails to make any payment hereunder when due
      and such failure continues for a period in excess of ten (10) days.

     (c) Distributor may, at any time and in its sole discretion, upon not less
than ninety (90) days written notice to Company, terminate this Agreement for
any reason.  In such event, Company shall complete manufacture and packaging of
all Product currently on order, and Distributor shall purchase and pay for such
Product.  Distributor shall also pay Company's costs for all materials

Product at Distributor's purchase price therefor under paragraph 3.  Upon
termination of this Agreement for any reason, all related subdistributorship,
agency or dealership agreements 

                                     13
<PAGE>   14

entered into by Distributor shall be automatically terminated.  If
Company does not request return of Product held by Distributor, Distributor
shall have six (6) months from the date of termination within which to sell the
Products, subject to all the terms and conditions of this Agreement

     (e) No termination pursuant to this Agreement shall give rise to any
obligation by either party to the other except as specifically provided in this
Agreement.  In particular, each party agrees that it shall not be entitled to
any payment, whether by way of compensation, indemnity or penalty, arising out
of such termination.  Any pre-existing claims, however, shall not be waived by
the parties as a result of such termination.

     (f) In addition to any other rights it may have at law or in equity, if
Distributor breaches this Agreement and fails to cure such breach pursuant to
paragraph 10(b)(i) or (iv) above, the Company may on notice to Distributor
unilaterally amend the appointment in paragraph 1 to be as non-exclusive
distributor.

     11. INSURANCE.

     Distributor shall obtain and maintain, at its expense, product liability
insurance which includes the Product in an aggregate amount for all products of
not less than Ten Million US Dollars ($10,000,000).  All such insurance shall

have such deductibles as are acceptable to Company, in its reasonable
discretion.  Distributor shall provide a certificate of insurance evidencing
such insurance concurrently with the execution of this Agreement and will
provide new certificates complying with this Agreement at least thirty (30)
days in advance of the stated expiration date of the period of coverage.  Each
such certificate shall recite that the subject insurance is not cancelable and

shall not be required to make any payment) to obtain at the earliest
practicable date, by instruments in form and substance reasonably satisfactory
to Distributor, all consents and approvals to the assignment of material
agreements for the supply of Product to customers within the Territory.  If,
with respect to any agreement to be assigned, a required consent to the
assignment is not obtained Company shall use reasonable efforts to keep in
effect and give Distributor (at Distributor's cost and expense) the benefit of
such agreement to the same extent as if it had been assigned and to the extent
not prohibited by that agreement, and Distributor shall perform Company's
obligations under the agreement or cooperate in Company's performance of such
obligations.  Nothing in this Agreement shall be construed as an attempt to
assign any agreement that is by its terms nonassignable without the consent of
the other party.

Date.  Distributor agrees to be responsible for all costs and expenses with
respect to the return of Product shipped on or after the Effective Date.

     (b) Distributor and Company shall track lot numbers for the purposes of
identifying when Product was sold.  For those lots for which both

4.   Compensation.

     (a)  Salary.  For any and all services performed by Executive under this 
          Agreement during the Term, the Company shall pay to Executive an
          annual salary of Two Hundred Fifty Thousand ($250,000) per year (the
          "Salary").  The Salary shall be paid in equal installments no less
          frequently than monthly and in accordance with Company practice, 
          prorated, however, for any period of less than a full month.  The 
          Salary will be reviewed annually by the Board and a determination 
          shall be made by the Board as to the appropriateness of an increase,
          if any, thereto.

     (b)  Bonus.  In addition to the Salary, Executive shall be eligible to 
          receive from the Company an incentive compensation bonus (the
          "Bonus") of up to 50% of his Salary.  The Bonus, if any, shall be
          determined based on the achievement by the Company of certain
          specific strategic plans and goals (the "Strategic Goals") during     
          the preceding calendar year (the "Measurement Period") as shall be
          determined by the Board following its consideration of 
          recommendations from the Executive.  The Strategic Goals for each
          Measurement Period shall be established as promptly as possible in
          each such Measurement Period, with the expectation that the Strategic
          Goals be in place each year prior to distribution of the Company's
          annual proxy materials.  Following each Measurement Period, the
          Compensation Committee of the Board shall review the Strategic Goals
          for the prior Measurement Period in light of the Company's actual
          performance during such Measurement Period. Achievement of various
          levels of the Strategic Goals shall result in the following payments
          as a percentage of Salary:

                Payment of each year's Bonus, if any, shall be made promptly
          after the amount of such Bonus is ascertainable and in no event       
          later than March 31 in the year following the year with respect to
          which the Bonus shall be owed.  In addition, and at its sole
          discretion, the Board may award additional compensation to Executive
          based on Executive's contributions to the Company.

5.   Benefits and Other Rights.  In consideration for Executive's performance
     under this


                                       2



<PAGE>   3

     Agreement, and in addition to the payments provided in Section 4, the
     Company shall provide to Executive the following benefits:
     (a)  The Company will reimburse Executive for, or provide cash
          advances for, all  reasonable  out-of-pocket business expenses
          incurred by Executive in connection with his employment hereunder;
          provided, Executive adheres to any and all reasonable policies
          established by the Company from time to time with respect to such
          reimbursements or advances, including, but not limited to, a
          requirement that Executive submit supporting evidence of any such
          expenses to the Company.
     
     (b)  The Company will provide Executive with a monthly car
          allowance in the amount of one thousand dollars ($1,000.00) net of
          tax cost to the Executive.
     
     (c)  During the Term, Executive shall be entitled to participate
          in any employee benefit plans (including, but not limited to, any
          life insurance, disability, medical, dental, hospitalization,
          savings, retirement, and other benefit plans of the Company) then in
          effect for executive officers of the Company and to receive any
          other fringe benefits that the Company then provides to executive
          officers of the Company to the extent Executive meets the
          eligibility requirements for any such plan or benefit.
     
     (d)  (i) Executive shall be provided $1,200,000 term life
          insurance protection with the death benefit payable to Executive's
          estate (or as Executive otherwise directs) and (ii) Executive shall
          be permitted to participate in the Company's existing 401(k) plan,
          with the Company making matching contributions in accordance with
          said plan.
     
     (e)  During the Term the Executive shall be entitled to four (4)
          weeks paid vacation, it being understood and agreed that unused
          vacation shall not be carried over from one year to the next.
     
     (f)  The Company will pay Executive's dues at Exmoor Country Club
          and the other expenses payable to maintain Executive's membership
          and use privileges at the club such as the annual fees payable as a
          condition to use of the golf, tennis and other facilities for which
          an annual fee is payable, the annual employee fund and other
          analogous charges up to a maximum of $10,000 per year at current
          rates, but subject to adjustment during the Term as such dues and
          fees may be increased.
     
     (g)  At the direction of the Executive, the Company shall make a
          charitable donation of Ten Thousand Dollars ($10,000) to either
          Thunderbird or Mercy each year during the Term, beginning with a
          contribution in 1997.
     
     (h)  The Company will purchase such equipment as Executive
          reasonably deems necessary to enable him to perform work for the
          Company from his home or while
     

                                       3



<PAGE>   4

          traveling, including an office computer and fax machine, a portable
          computer and a cellular phone.  These items will remain the   
          property of the Company, but Executive will have exclusive use of
          these items during his employment term.  From time to time, the
          equipment will be upgraded as Executive reasonably requests to keep
          pace with technological developments and his needs.

     (i)  The Company will reimburse the Executive for the reasonable
          costs of travel, lodging and other incidental costs associated with
          Executive's participation as a board member of Thunderbird and
          Mercy, to the extent that such costs are not reimbursed by such
          entities.
     
     (j)  The Company will indemnify Executive against claims arising
          out of Executive's service with the Company to the fullest extent
          permitted by law and the Company's Certificate of Incorporation and
          will include Executive under the coverage provided by the Company's
          existing D&O insurance policy during the term of his employment
          hereunder and, if permitted to do so by its D&O carrier at no more
          than nominal cost to the Company, for a period of five years after
          termination of employment.
     
     (k)  During the Term, the Company shall provide Executive with
          such other employment benefits as may from time to time be made
          generally available to employees of the Company; provided, however,
          that the Company shall not be required to establish and maintain any
          specific benefits or benefit plans.
     
6.   Options.   (a) As of November 13, 1997, the Compensation and Stock Option
     Committee of the Board of Directors (the "Committee") shall grant to
     Executive stock options pursuant to the terms and conditions of the
     Company's 1991 Stock Option Plan (the "Option Plan"), as amended, to
     purchase 400,000 shares of the Company's common stock (the "Options"), at
     an exercise price per share of $7.50 which is the fair market value of the
     Company's common stock on the date of grant.  The options granted to the
     Executive will expire ten years from the date of grant.  Of the Options
     granted to Executive, 66,665 Options shall be incentive stock options
     ("ISOs") which will vest at the rate of 13,333/year (based on the exercise
     price of $7.50) on November 13 of each of the five years 1997-2001.  The
     remaining Options shall be granted under the Option Plan as non-qualified
     stock options ("NQOs").  There will be immediate vesting of 36,667 NQO
     Options (which represents the difference between 50,000 shares and the
     number of shares vested in 1997 under the ISO described above).  The
     remaining NQOs (the "Monthly NQOs") will vest at a uniform rate of 6,180
     NQO options on the 13th day of each of the 47 consecutive months beginning
     with December 1997 with a final vesting of 6,208 NQO options on the 13th
     day of the 48th month.  2,083 of the Monthly NQOs in each of the first 47
     months and 2,099 of the Monthy NQOs in the 48th month (for a total of
     100,000 NQO options) shall not be exercisable until the attainment of
     certain "milestone achievements" which are to be mutually agreed to by the
     Board and the Executive within


                                       4



<PAGE>   5

     90 days of the date of the Employment Agreement.  The milestone options
     shall become purchasable in chronological order as the milestones are
     achieved so that, for example, if and when milestones are achieved which   
     render one-half of the milestone option shares purchasable, then the
     milestone requirement would not then thereafter restrict purchases through
     the 24th of the 48 monthly vesting installments.  The Company agrees to
     allow the Executive to exercise Options on a cash-less basis (to the
     extent permitted by the Option Plan) or, if not permitted by the Option
     Plan, to use its best efforts to amend the Option Plan to allow such
     exercise in accordance with current law, including, but not limited to,
     applicable regulations of the Securities and Exchange Commission.

          (b)   Upon exercise of any Options, Executive may request that the
     Company provide Executive with a loan (the "Loan" or if multiple loans are
     requested the "Loans") in an amount sufficient to purchase the shares
     subject to such exercised Options, up to a maximum for all Loans of an     
     amount sufficient to exercise Options for 100,000 shares of the Company's
     stock, each such Loan to be evidenced by a promissory note (the "Note" and
     collectively the "Notes") which shall provide for an interest rate equal
     to the Applicable Federal Rate of interest authorized by Section 1274(d)
     of the Internal Revenue Code, as amended, be secured by  the Company
     shares so acquired, require payment of interest annually on each November
     13, provide for payment of principal as a lump sum on the earlier to occur
     of four (4) years from the date of the Note or one (1) year from the date
     of termination of employment and contain such other terms as the Company
     and Executive shall reasonably agree.

          (c)   The Option Plan is currently registered under the Securities Act
     of 1933 and the Company hereby commits to maintain such registration in    
     effect until Executive's Options are fully exercised.

7.   Termination of the Agreement.

     (a)  The Company shall have the right to terminate the Agreement,
          effective upon delivery of written notice of termination to
          Executive under the following circumstances:

          (i)   Executive shall die or shall be deemed to be
                Permanently Disabled (as defined in Section 9 below);
          
          (ii)  Without Cause (as hereinafter defined), effective
                immediately upon delivery of written notice to Executive by
                the Company; or
          
          (iii) With Cause, it being agreed that Executive's employment shall 
                not be deemed to have been terminated for Cause unless the
                primary reason for Executive's termination shall be that:
          
          

                                       5



<PAGE>   6


                (1)  Executive has been convicted of (or plead guilty or nolo 
                     contendere to) a felony; or



                                       6



<PAGE>   7

                (2)  Executive has engaged in embezzlement.
                
          The Executive may not be terminated for Cause unless there shall be
          been delivered to the Executive a copy of a resolution duly adopted
          by the affirmative vote of a majority of the Board of Directors of
          the Company, at a meeting of that Board held after reasonable notice
          to the Executive of the purpose for the meeting and an opportunity 
          for the Executive to be heard at such meeting), finding that in the 
          good faith opinion of the Board the Executive shall have engaged in
          conduct described in clause (1), (2) or (3) above and specifying the
          particulars thereof.  Such a finding by the Board of  Directors of
          the Company shall be a prerequisite to a termination for Cause, but
          such a finding shall not preclude the Executive from seeking a
          determination by means of an arbitration proceeding pursuant to
          Section 13 of this Contract that Cause did not exist for such
          termination.  Any termination of the Executive's employment by the
          Company which shall not be for Cause as defined in this Section shall
          be deemed to be "not for Cause."

     (b)  This Agreement may be terminated by the Executive at any time
          upon thirty (30) days prior written notice to the Company.

     (c)  Upon termination pursuant to Section 7(a)(i) or 7(a)(ii) the
          Company shall (i) reimburse Executive, or his estate, when and as
          otherwise due in accordance with Section 5, for his expenses accrued  
          through the date of termination, plus (ii) compensate Executive, or
          his estate, through the end of the month in which the termination
          occurs for the regular monthly portion of his Salary, plus (iii) pay
          to Executive the "applicable incentive percentage" (as herein
          defined) of Executive's Salary paid in the year of termination
          through the end of the month in which termination occurs, plus (iv)
          pay an amount per day for any accrued but unused vacation time
          compensated at the rate of Salary for the current year plus Bonus
          paid for the prior Measurement Period, plus (v) pay an amount equal
          to any Bonus for the prior year which has been earned and awarded but
          not yet paid.  As used herein, "applicable incentive percentage" will
          be the percentage of incentive compensation Executive earned for the
          preceding Measurement Period (expressed as a percentage of
          Executive's salary in that year), provided that if Executive's
          employment is terminated in 1998, the applicable percentage will be
          0%.  For example, if a termination of employment were to occur after
          1998 on a June 15, at a time when Executive's salary was $250,000,
          his Bonus for the prior Measurement Period (which has been paid) had
          been 40% ($100,000) and he had two weeks unused


                                       7



<PAGE>   8

          vacation time and no reimbursable expenses, the Company would be
          obligated to make the following payments: $20,833.33 of Salary
          (assuming that no portion of his monthly salary had been paid in
          June), plus, $50,000 (representing the applicable incentive   
          percentage of $250,000 x 40% x .5 = $50,000), plus $13,461.54 for
          unused vacation ($250,000 + $100,000 divided by 52 x 2 = $13,461.54),
          for a total of $84,294.87.  In addition to the foregoing payments,
          after a termination under Section 7(a)(i) or 7(a)(ii), the Company
          will pay Executive or Executive's estate, an amount equal to
          Executive's annual Salary as in effect at the time of termination,
          payable in 12 equal monthly payments.  Finally, upon a termination
          under Section 7(a)(i) or 7(a)(ii) medical, dental and disability
          benefits will be extended, on the same terms as if Executive had
          continued to be an employee of the Company, for a period of
          twenty-four (24) months.

     (d)  Upon termination in accordance with Section 7(a)(iii) or 7(b), the 
          Company shall (i) pay the Executive all Salary accrued but unpaid as
          of the date of such termination, (ii) reimburse the Executive, when
          and as otherwise due in accordance with Section 5, his expenses
          accrued through the date of termination, and (iii) pay any Bonus
          earned but not yet paid for any year prior to the year in which the
          termination occurs.

     (e)  Any dollar amounts which are to be paid at the time of termination 
          under this Section (other than any Salary continuation under Section
          7(c)) shall be paid promptly upon termination of employment, but in
          no event more than thirty (30) days after the date of termination.
          Any salary continuation payments shall be made in accordance with the
          normal payroll policies of the Company.  All payments made pursuant
          to this Section 7 shall be subject to all appropriate withholding
          taxes.

     (f)  The Company's Board will, with input from Executive, develop an 
          appropriate "golden parachute" compensation package in which
          Executive and other key executives would participate in the event of  
          a take over or other change in control.  The plan will include
          features included in such plans at public companies in the same
          industry as and of similar size as the Company.

8.   Effect of Expiration or Termination of the Agreement.  Promptly
     following the expiration or termination of this Agreement, and except
     as provided in Section 7 or as otherwise expressly agreed by the Company:

     (a)  Executive's duties shall cease as of the effective date of
          termination; provided, however, the Executive shall provide the
          Company with all reasonable assistance necessary to permit the        
          Company to continue its business operations without interruption
          and in a manner consistent with reasonable business practices,
          provided that such transition period shall not exceed thirty (30)
          consecutive days after termination nor require more than twenty (20)
          hours of Executive's time per


                                       8



<PAGE>   9

          week.  In the event that the Company shall request Executive to
          provide transitional assistance after the effective date of   
          termination, Executive shall be paid at any hourly rate based on a
          2,080 hour work year and his then current Salary, based upon time
          sheets submitted by Executive specifying the services performed and
          the amount of time expended;

     (b)  Executive shall deliver to the Company possession of any and
          all property owned or leased by the Company which may then be in
          Executive's possession or under his control, including without        
          limitation, any and all such keys, credit cards, telephones,
          automobiles, equipment, supplies, books, records, files, computer
          equipment, home office equipment purchased by the Company for
          Executive's use, computer software and other such tangible and
          intangible property of any description whatsoever.  If, following the
          expiration or termination of the Agreement, Executive shall receive
          any mail addressed to the Company, Executive shall immediately
          deliver such mail, unopened and in its original envelope or package,
          to the Company; and

     (c)  Other than as provided in Section 7, upon a termination of
          employment Executive's participation in all other benefits or
          entitlement to participate in Company programs or benefits, if any,
          shall be determined in accordance with the Company's employee benefit
          plans and other applicable programs and practices then in effect;
          provided, however, that all policies of life insurance, if any,
          relating solely to Executive shall be assigned to Executive within
          thirty (30) days following termination, provided that such assignment
          shall be at no cost or expense to the Company, and provided further
          that such assignment shall state that it is made subject to the terms
          and conditions of the policy(ies).

9.   Definition of "Permanently Disabled".  Executive shall be deemed to be
     "Permanently Disabled" upon ninety (90) days after the first to occur of
     either of the following:

     (a)  The Company shall receive a written certificate from a physician 
          selected by the Company, and reasonably acceptable to the Executive,
          stating that, based upon one or more examinations of Executive by
          such physician made at the Company's request, it is such physician's
          opinion that for a period of at least six (6) consecutive months from
          the date of such certification Executive is and will be substantially
          unable to perform his duties hereunder or that it would seriously
          impair his physical or mental health to perform such duties; or

     (b)  Executive shall be adjudicated as an incompetent or disabled
          person and a conservator or a guardian shall be appointed for his     
          person or property by a court of competent jurisdiction.

10.  Inventions and Discoveries.



                                       9

     (a)  Executive shall promptly and fully disclose to the Company, and with
          all necessary detail for a complete understanding of the same, all
          developments, know-how, discoveries, inventions, improvements,
          concepts, ideas, writings, formulae, processes and methods of a
          financial or other nature (whether copyrightable, patentable or
          otherwise) made, received, conceived, acquired or written during
          working hours, or otherwise, by Executive (whether or not at the
          request or upon the suggestion of the Company) during the period of
          his employment with the Company or any of its subsidiaries, solely or
          jointly with others, in or relating to any activities of the Company
          or its subsidiaries known to him as a consequence of his employment
          with the Company (collectively the "Subject Matter").

     (b)  Executive hereby assigns and transfers, and agrees to assign and 
          transfer, to the Company, all his rights, title and interest in and
          to the Subject Matter, and Executive further agrees to deliver to the
          Company any and all drawings, notes, specifications and data relating
          to the Subject Matter, and to execute, acknowledge and deliver all 
          such further papers, including applications for copyrights or
          patents, as may be necessary to obtain copyrights and patents for any
          thereof in any and all countries and to vest title thereto to the
          Company.  Executive shall assist the Company in obtaining such        
          copyrights or patents during the term of this Agreement, and any time
          thereafter on reasonable notice and at mutually convenient times, and
          Executive agrees to testify in any prosecution or litigation
          involving any of the Subject Matter, provided however, that Executive
          shall be compensated in a timely manner at the rate of $100.00 per
          hour (with a minimum of $500 per day), plus out-of-pocket expenses
          incurred in rendering such assistance or giving or preparing to give
          such testimony if it is required after termination of his employment.

11.  Confidentiality.  The Executive acknowledges that during the period of
     his employment by the Company, and in his performance of services
     hereunder, he will be placed in a relationship of trust and confidence
     regarding the Company and its affairs.  In the course of and due to that
     relationship he will have contact with the Company's customers, suppliers,
     affiliates, and distributors and their personnel.  In the course of the
     aforesaid relationship, he will have access to and will acquire
     confidential information relating to the business and operations of the
     Company, including, without limitation, information relating to processes,
     plans and methods of operation of the Company.  The Executive acknowledges
     that any such information that is not a trade secret, nonetheless
     constitutes confidential information as between himself and the Company,
     that the disclosure thereof (or of any information which he knows relates
     to confidential, trade, or other secret aspects of the Company's business)
     would cause substantial loss to the goodwill of the Company, and will
     continue to be made known to Executive only because of the position of
     trust and confidence which he will continue to occupy hereunder.  In view
     of the foregoing, and in consideration of the covenants and premises of
     this Agreement, the Executive agrees that during the term of this
     Agreement and at all times thereafter, Executive shall not in any manner,
     either directly or indirectly, divulge, disclose or communicate to any
     person or


                                       10



<PAGE>   11

     firm, except to or for the Company's benefit as directed by the Company,
     any of the confidential information which he may have acquired in the
     course of or as an incident to his employment by the Company, the parties
     agreeing that such information affects the successful and effective
     conduct of the business and goodwill of the Company and that any breach    
     of the terms of this Section 11 is a material breach of this Agreement.
     Notwithstanding the foregoing, nothing in this Section 11 shall preclude
     Executive from disclosing confidential information pursuant to law or
     court order or disclosing confidential information which has been made
     public through the release or disclosure by persons other than Executive.



                                       11

12.  Remedies.

     (a)  The covenants of Executive set forth in Section 11 are separate and 
          independent covenants for which valuable consideration has been paid,
          the receipt, adequacy and sufficiency of which are acknowledged by
          Executive, and have also been made by Executive to induce the Company
          to enter into this Agreement.  Each of the aforesaid covenants may be
          availed of, or relied upon, by the Company in any court of competent
          jurisdiction, and shall form the basis of injunctive relief and
          damages including expenses of litigation suffered by the Company
          arising out of any breach of the aforesaid covenants by Executive.    
          The covenants of Executive set forth in this Section 12 are
          cumulative to each other and to all other covenants of Executive in
          favor of the Company contained in this Agreement and shall survive
          the termination of this Agreement for the purposes intended.

     (b)  Each of the covenants contained in Section 11 above shall be
          construed as agreements which are independent of any other provision
          of this Agreement, and the existence of any claim or cause of action  
          by any party hereto against any other party hereto, of whatever
          nature, shall not constitute a defense to the enforcement of such
          covenants.  If any of such covenants shall be deemed unenforceable
          but may be made enforceable by the imposition of limitations thereon,
          Executive agrees that the same shall be enforceable to the fullest
          extent permissible under the laws and public policies of the
          jurisdiction in which enforcement is sought.  The parties hereto
          hereby authorize any court of competent jurisdiction to modify or
          reduce the scope of such covenants to the extent necessary to make
          such covenants enforceable.

13.  Arbitration.  Any claims, disputes or controversies arising out of or
     relating to this Agreement between the parties (other than those arising
     under Section 12) shall be submitted to arbitration by the parties.  The
     arbitration shall be conducted in Chicago, Illinois in accordance with the
     rules of the American Arbitration Association then in existence and the
     following provisions: Either party may serve upon the other party by
     guaranteed overnight delivery by a nationally recognized express delivery
     service, a written demand that the dispute, specifying in detail its
     nature, be submitted to arbitration.  Within seven business days after the
     service of such demand, each of the parties shall appoint an arbitrator
     and serve written notice by guaranteed overnight delivery by a nationally
     recognized express delivery service, of such appointment upon the other
     party.  The two arbitrators appointed shall appoint a third arbitrator.
     The decision of two arbitrators in writing under oath shall be final and
     binding upon the parties.  The arbitrators shall decide who is to pay the
     expenses of the arbitration. If the two arbitrators appointed fail to
     agree upon a third arbitrator within ten days after their appointment,
     then an application may be made by either party, upon notice to the other
     party, to any court of competent jurisdiction for the appointment of a
     third arbitrator, and any such appointment shall be binding upon both
     parties.

questions with respect to the Manufacturing Know-How. Such meetings shall not
exceed four (4) eight (8) hour days in number, or result in



                                        3

<PAGE>   7


Syntex or its Affiliates having to conduct any additional activities or make any
additional expenditures in time or money whatsoever with respect to Unimed's
research or development of the Product. In no event shall Syntex or its
Affiliates be required to create, develop, search for, or deliver additional
Know-How to Unimed beyond the Manufacturing Know-How. Moreover, to the extent
reasonably possible, Unimed shall reduce to writing all questions of Syntex or
its Affiliates and give same to Syntex or its Affiliates in advance of any
meeting.

     2.3  OBSERVATION. During the Campaign, Syntex or its Affiliates will allow
Unimed personnel to visit its facilities in order to facilitate Unimed in
learning the Know-How necessary to manufacture and package Product. Any expenses
incurred by Unimed shall be solely for its own account. During such visits,
Unimed shall fully cooperate with Syntex or its Affiliates and its personnel,
including but not limited to: (i) obtaining Syntex's or its Affiliates' and if
necessary, DEA security clearance prior to any entry into the manufacturing and
packaging area of the Plant (the "Manufacturing Area"); (ii) providing Syntex or
its Affiliates with written physician's reports for each Unimed employee who
will enter the Manufacturing Area prior to any entry into the Manufacturing Area
stating that such employees are certified to use a respirator while in the
Manufacturing Area; and (iii) meeting all other additional reasonable
requirements of Syntex's or its Affiliates' Environmental Health Services
department, including, attending a mandatory drug, safety training workshop
prior to entering the Manufacturing Area. The parties acknowledge that the
Campaign has been concluded prior to execution of this Agreement.

     2.4  MAINTENANCE OF RECORDS. During the term hereof and subject to the
limitations set forth in this subsection and for a period of five (5) years
thereafter (or such longer period as may be required by law), Syntex or its
Affiliates or third party contractors shall maintain, and shall grant Unimed
access to, all books and records related to manufacture of the Product hereunder
at reasonably agreed upon times, provided, however, that if the FDA has
requested an immediate response, Syntex or its Affiliates shall permit Unimed
immediate access to such books and records as soon as reasonably possible.
Immediate access shall be defined as at least one business day from notification
of request, though Syntex shall endeavor to respond more promptly if possible.

     2.5  TERMINATION OF TECHNOLOGY TRANSFER. It is the intentions of both
parties to complete the transfer of Manufacturing Know-How and Product as soon
as possible and thus early meetings are encouraged. Upon termination of the
Campaign, Syntex shall, to the extent resources are available, which
determination shall be made in Syntex' sole discretion, be available for
reasonable amounts of telephone discussions and hands-on support. Unimed shall
pay all travel costs and an hourly rate for consulting for hands-on support to
be mutually agreed upon by the parties.

     3.   SUPPLY.

     3.1  SINGLE CAMPAIGN. Syntex has manufactured one campaign of three batches
of the Product at the Plant (the "Campaign"). Syntex shall have no further
obligation to manufacture the Product. After Unimed provides to Syntex a
shipping address in the Territory, and after Syntex receives the Initial Payment
(as hereinafter defined), Syntex shall provide Unimed with Product in finished
dosage form in accordance with the Specifications and in accordance with the
quantity and timing schedule as set forth in Appendix C, attached hereto and
made a part hereof. Such Product will be shipped F.O.B., the Plant, to one DEA
Site as designated by Unimed. Unimed must supply  




                                        4

<PAGE>   8






to Syntex a copy of the DEA Certificate indicating that the destination
designated by Unimed is a DEA Site prior to shipping. Appendix C describes all
of the Product which shall be provided by Syntex to Unimed.

     3.2  LABELING. The Product shall be packaged in unlabeled bottles of 100
tablets per bottle. The bottles will be identified with the Syntex lot number.
One thousand bottles will have Syntex or Hoffmann-La Roche Ltd. labeling at no
charge to Unimed. All remaining bottles of the Product will be labeled with
Unimed labeling at cost and shall be invoiced by Syntex to Unimed.

     3.3  CLINICAL SUPPLIES. Syntex shall manufacture for Unimed approximately
500 bottles of 100 tablets each of the Product for use by Unimed in the Studies.
Such Product shall be delivered to Unimed in accordance with the timing schedule
set forth in Appendix C. Syntex will mark and score such Product in accordance
with written instructions from Unimed.

     3.4  ADDITIONAL ACTIVE INGREDIENT. Syntex or one of its Affiliates shall
sell to Unimed Active Ingredient to the extent such Active Ingredient is
available, pursuant to written purchase orders which may be submitted by Unimed
to Syntex. The price of the Active Ingredient shall be $3,300 per kilo.

     3.5  QUALITY. The Product and the Active have been or will be manufactured,
packaged, and stored in accordance with the Specifications and with applicable
laws, rules, orders, regulations and FDA requirements (including Good
Manufacturing Practices); provided, however, that the parties acknowledge the
fact that there is a Foreign Related Substance ("FRS") in the Active Ingredient
and the provisions of Section 3.6 supersede the warranty set forth herein. The
Product shall be deemed to have met Specifications unless Unimed notifies Syntex
that the Product does not meet Specifications within sixty (60) days after the
first receipt by Unimed or its designee of the finished Product. If there is a
difference of opinion concerning the conformance of the Product, Syntex and
Unimed agree to consult with each other in order to explain and resolve the
discrepancy between each other's determinations. If, after good faith attempt by
the parties to do so, such consultation does not resolve the discrepancy, Syntex
and Unimed agree to nominate an independent, reputable laboratory, acceptable to
both parties, that shall repeat the applicable Methods of Analysis on
representative samples from the Campaign provided by both Syntex and Unimed, and
the resulting determinations shall be binding on Syntex and Unimed for the
purposes hereof. The party whose assertion as to the conformity or nonconformity
of the Product in question is not borne out by the results of testing by the
independent laboratory shall bear all costs and expenses of such testing.

     3.6  FRS IN ACTIVE INGREDIENT. The parties acknowledge that there is an FRS
in the Active Ingredient and the parties are endeavoring to solve the problem in
accordance with Section 3.7. Until the NDA Supplement is approved by the FDA,
and there is no guaranty that it will be approved, the Product may not be sold
commercially but only supplied under the investigator-held IND for compassionate
use.

     3.7  IDENTIFICATION OF FRS. Syntex will identify a party, either within or
outside Syntex, to attempt to identify the FRS. Syntex is responsible for
contracting with an outside party to identify the FRS. If the FRS is
successfully identified, Syntex and Unimed shall share the cost for that work
equally, up to a total cost of twenty-five thousand dollars ($25,000) each. If
the FRS is 


                                       5

<PAGE>   9



not successfully identified, Syntex shall pay all costs for that work. If the
cost of identifying the FRS exceeds a total of fifty thousand dollars ($50,000),
Unimed and Syntex shall negotiate in good faith the manner in which the cost is
to be allocated between the parties. In no event, however, will Syntex be
obligated to expend more than one hundred thousand dollars ($100,000) to
identify the FRS.

     4.   REPRESENTATIONS, WARRANTIES, AND COVENANTS.

     4.1  MANUFACTURING COMPLAINTS. Notwithstanding anything contained herein to
the contrary, Syntex or its Affiliates or its third party contractors shall
maintain books and records related to Product-related customer complaints (i.e.
complaints relating to the manufacture of the Product, but not complaints
relating to the Product itself or adverse reactions) concerning the Product for
twenty-four (24) months after the Effective Date.

     4.2  STABILITY STUDIES. As soon as possible following the execution of this
Agreement, Unimed shall qualify a testing site for stability studies. Syntex
shall transfer all ongoing stability studies for the Product and the
responsibility therefor to Unimed immediately upon qualification of such a site.

     4.3  COMPASSIONATE USE. Unimed shall supply the Product on a compassionate
use basis as requested for the treatment of Fanconi's Anemia. Upon execution of
this Agreement, Syntex shall send a letter to the Fanconi's Anemia Society
informing them that Unimed now owns the Registrations and that further inquiries
and requests with respect to the Product should be directed to Unimed. In
addition, Syntex shall forward all Compassionate Use requests to Unimed and send
a letter to the inquirer informing the inquirer of the same. Unimed shall
continue to fulfill this obligation regardless of whether the NDA Supplement is
approved for so long as tablets are available; provided, however, that once
tablets are available for commercial sale, Unimed may cease distribution under
the Compassionate Use Program.

     4.4  NDA. Syntex represents and warrants that (i) each of the NDA and the
NDA Supplement is accurate and complete in all material respects and has been
amended and supplemented as required by law up to the date of this Agreement;

any reason. An NDA Supplement has been filed with respect to the FRS issue in
the Active Ingredient. A complete and accurate copy of such NDA Supplement has
been provided to Unimed.

     4.5  NDA SUPPLEMENT. Following Closing, Unimed will be responsible for any
regulatory work, including the NDA Supplement.

     4.6  LITIGATION. Syntex represents that to the best of its knowledge,
neither Syntex nor any of its Affiliates has been a party to any product
liability litigation in the United States since 1991.

     4.7  INFRINGEMENT. As of the date hereof, Syntex has no knowledge and has,
to the best of its knowledge, received no notice that the manufacture, packaging
or sale of Product in the Territory as contemplated herein conflicts with or
violates any existing patents, proprietary information or other intellectual
property rights of any third party.



                                        6

     4.8  NON-COMPETE. For the five (5) year period following the date hereof,
neither Syntex nor any of its Affiliates shall directly or indirectly,

except with respect to this Campaign, which will be sold to Unimed pursuant to
this Agreement.

     5.3  TRADEMARKS. Syntex hereby assigns and transfers to Unimed all of
Syntex's right, title and interest in the Trademarks. Following Closing, Unimed
shall prepare and Syntex shall execute such documents as Unimed may reasonably
request in order to record the assignment of the Trademarks. The responsibility
and expense of preparing and filing such documents and any actions required
ancillary thereto, shall be borne solely by Unimed. Nothing contained herein
shall be deemed to transfer to Unimed any rights to any trademarks outside the
Territory, including but not limited to the right to use the Trademarks outside
the Territory. In addition, Syntex makes no representations or warranties that
the use of the Trademarks outside the Territory will not violate or infringe any
other trademark.

     5.4  REGISTRATIONS. Syntex shall promptly assign and transfer to Unimed all
of Syntex's right, title and interest in and to the Registrations. Syntex
represents that to the extent requested by Unimed, it has provided access to
true and complete copies of the NDA prior to Closing. As soon as reasonably
possible after Closing, Syntex shall transfer the originals of the NDA and the
Canadian DIN to Unimed. Upon execution of this Agreement, Syntex shall execute a
letter to each of the FDA and the Canadian HPB transferring the Registrations.

     5.5  DMF. Syntex shall promptly assign and transfer the DMF to Unimed;
provided, however, that Unimed shall permit Syntex and its designees to

     6.   CONSIDERATION.

     6.1  PAYMENTS. In consideration of the sale, conveyance, assignment,
transfer and

<PAGE>   11


delivery of the assets set forth in Article 5, Unimed shall be obligated to pay
Syntex a total of XXXXX dollars ($XXXXX) as of the Effective Date (the "Purchase
Price"). Unimed shall pay Syntex XXXXX dollars ($XXXXX) at the Effective Date
("Initial Payment"). Unimed's obligation to pay the remaining XXXXX dollars
($XXXXX) is contingent upon the NDA Supplement being approved by the FDA
("Additional Payments"). If the NDA Supplement is approved by the FDA, Unimed

          6.1.1 XXXXX dollars ($XXXXX) within thirty (30) days of approval of
     the NDA Supplement;

          6.1.2 XXXXX dollars ($XXXXX) within one hundred eighty (180) days
     after approval of NDA supplement;

          6.1.3 XXXXX dollars ($XXXXX) within three hundred sixty (360) days
     after approval of NDA supplement.

     6.2 ADDITIONAL PAYMENTS. Unimed shall not be obligated to pay to Syntex any

within two (2) years of the Effective Date.

     6.3 ROYALTIES. In consideration of the assignments contemplated in Article
5 hereof, Unimed shall pay Syntex a royalty of XXXXX percent (XXXXX%) of Net

     6.4  REDUCTION OF ROYALTIES.

     documentation, if Unimed determines that Substantial Competition exists in
     the Territory and shall indicate the date when it reasonably believes the
     Substantial Competition commenced. Upon Unimed's providing such notice and
     reasonable documentation, Syntex may agree or disagree with Unimed's
     determination. If Syntex agrees with Unimed's determination, Unimed may
     reduce the royalty from XXXXX percent (XXXXX%) to XXXXX percent (XXXXX%) of
     Net Sales of Product sold in the Territory by the Unimed Group from the
     date on which the Substantial Competition commenced, for so long as the
     Substantial Competition continues. If Syntex disagrees with Unimed's
     determination, Syntex shall provide Unimed with reasonable documentation
     upon which Syntex bases its disagreement, and the parties agree to discuss
     in good faith resolution of the disagreement.

          6.4.2 Unimed shall promptly notify Syntex when Substantial Competition
     in the Territory no longer continues and shall indicate the date when the

<PAGE>   12



     Competition ceased.

          6.4.3 Syntex may, at its option, notify Unimed in writing if Syntex
     determines that Substantial Competition in the Territory no longer
     continues and shall indicate the date when it reasonably believes the
     Substantial Competition ceased. Upon Syntex's providing such notice and
     reasonable documentation, Unimed may agree or disagree with Syntex's
     determination. If Unimed agrees with Syntex's determination, Unimed shall
     pay Syntex a royalty of XXXXX percent (XXXXX%) of Net Sales of Product sold
     in the Territory by the Unimed Group from the date on which the Substantial
     Competition ceased. If Unimed disagrees with Syntex's determination, Unimed
     shall provide Syntex with reasonable documentation upon which Unimed bases
     its disagreement, and the parties agree to discuss in good faith resolution
     of the disagreement.

     7.   REPORTING.

years following the end of the reporting period to which they pertain, to the
inspection of a certified public accountant selected by Syntex (including an
employee of Syntex or its Affiliates) and reasonably acceptable to Unimed;
provided, however, that if there is a dispute over an audit conducted by an
employee of Syntex or its Affiliates, then Syntex shall select an independent
public accountant, reasonably acceptable to Unimed Syntex will pay for such
audit, unless it reveals an underpayment of royalties of five percent (5%) or
greater for the period being audited, upon which occurrence the cost will be
incurred by Unimed.

     8.   INDEMNITY AND WARRANTY.

     8.1  INDEMNITY BY UNIMED. Unimed will defend, indemnify, and hold harmless
Syntex and its Affiliates, the managers, directors, officers, employees, and

indemnify, or hold harmless Unimed or its Affiliates, managers, directors,
officers, employees, or agents of Unimed or its Affiliates, from or against any
or all Liabilities directly or indirectly resulting from Claims with

The rights of Syntex under this Section 10.1 shall not be affected in any way by
Syntex's waiver or failure to take action with respect to any previous Default.

     10.2 RIGHTS ON BANKRUPTCY. In the event Unimed becomes insolvent or
bankrupt, or shall have made an assignment for the benefit of its creditors, or

indirectly to any cause of any nature beyond the reasonable control of such
party, including, without in any way limiting the generality of the foregoing,

war, insurrection, riot, act of God or the public enemy, or any law, act, order,
export or import control regulations, actions by a regulatory authority,
proclamation, decree of a court of competent jurisdiction (not arising out of
breach of such party of this Agreement). In the event of a happening of such a
cause, the party invoking the Force Majeure shall not be liable to the other

period equal to the duration of the contingency which occasioned the delay,
interruption or prevention. The party invoking such Force Majeure shall notify
the other party within a period of thirty (30) days, stating

renders such notification impossible in which case notification will be made as
soon as possible. If the delay from the Force Majeure exceeds six (6) months,
both parties shall consult each other to find an appropriate solution. No event
of Force Majeure may be invoked to delay any payments under Article 6. provided
that all of the Products have been delivered to Unimed.

the benefit of the respective successors of the parties hereto, or to an
assignee of all of the good will and entire business and assets of a party
hereto, but shall not otherwise be assignable, without the prior written consent
of the other party, which consent will not be unreasonably withheld.
