ITEM 1.  BUSINESS

(a) GENERAL DEVELOPMENT OF BUSINESS

          Roberts Pharmaceutical Corporation (the "Company") is an international
pharmaceutical company which licenses, acquires, develops and commercializes
post-discovery drugs in selected therapeutic categories. The Company was
incorporated under the laws of the State of New Jersey in 1982 and commenced
operations in 1983. In 1988, its name was changed to Roberts Pharmaceutical
Corporation from VRG International, Inc. The Company's executive offices are
located at Meridian Center II, 4 Industrial Way West, Eatontown, New Jersey
07724, and its telephone number is (732) 389-1182. As used herein, the term the
"Company" refers to Roberts Pharmaceutical Corporation and its subsidiaries
unless the context indicates otherwise.

(b) FINANCIAL INFORMATION ABOUT INDUSTRY SEGMENTS

          Substantially all revenues, operating profits or losses and assets of
the Company are attributable to one line of business, the acquisition,
development and sale of pharmaceutical products, primarily prescription
pharmaceutical products.

(c)  DESCRIPTION OF BUSINESS

          The Company was founded to take advantage of the large and growing
opportunity to license, acquire, develop and commercialize post-discovery drugs
in selected therapeutic categories. The Company has organized its drug
development, acquisition and marketing activities to focus on late-stage
development drugs in Phase II or Phase III clinical trials and currently
marketed prescription pharmaceutical products which (i) do not meet the
strategic objectives or profit thresholds of larger pharmaceutical companies or
(ii) are made available by government agencies and research institutions. The
therapeutic categories targeted by the Company are Cardiovascular,
Gynecology/Endocrinology, Urology, Oncology, Hematology and Gastroenterology.

          The Company has a broad product portfolio including PROAMATINE(R) and
AGRYLIN/TM/, which are the Company's first proprietary drugs approved by the
U.S. Food and Drug Administration (the "FDA"). See "Approved Pipeline Products."
In addition, the Company has a number of other proprietary late-stage
development products in the Company's pipeline. See "Late-Stage Development
Products."

          During 1997, the Company continued the efforts commenced in 1995 and
1996 which were designed to concentrate the Company's business operations in its
core business of licensing, acquiring, developing and selling prescription
pharmaceuticals. The Company has since completed the sale of the core of its
nonprescription pharmaceuticals and has essentially completed the sale of its
home

                                      -2-
<PAGE>
 
care and medical products divisions ("Homecare"). See "Nonprescription
Pharmaceutical Products," "Prescription Pharmaceutical Products" and "Homecare."
Further, in March 1996, the Company announced its decision to discontinue and
divest the Company's clinical research business operations. The Company is in
the final stages of completing the sale of its contract clinical research
operations. See "Contract Clinical Research."

APPROVED PIPELINE PRODUCTS

          PROAMATINE(R).  In 1985, the Company acquired from the predecessor in
interest of Nycomed Pharma AG ("Nycomed Pharma") exclusive marketing rights in
the United States, Canada, the United Kingdom and Ireland to PROAMATINE
(midodrine), formerly AMATINE(R), a drug used for the treatment of orthostatic
hypotension and other blood pressure disorders. Orthostatic hypotension is a
condition involving the sudden drop in blood pressure upon assuming an upright
posture, resulting in dizziness, weakness or unconsciousness.

         In September 1996, the FDA approved the Company's New Drug Application
("NDA") for PROAMATINE and cleared PROAMATINE for marketing in the United States
for the treatment of symptomatic orthostatic hypotension. The Company commenced
marketing and sales activities in the U.S. with respect to PROAMATINE in the
fourth quarter of 1996.

          The FDA approved PROAMATINE pursuant to its accelerated approval
process for new drugs for serious or life threatening illnesses. There are no
other FDA approved treatments available for orthostatic hypotension. Other
current therapies used to treat the condition are associated with significant
adverse side effects such as potassium reduction, fluid retention and cardiac
and central nervous system disorders. The Company is conducting post-approval
and post-launch (Phase IV) studies of PROAMATINE as required as part of the FDA
approval. PROAMATINE is in Phase II trials for stress urinary incontinence. See
"Late Stage Development Products -Therapeutic Category - Urology."

          PROAMATINE for orthostatic hypotension has been designated by the FDA
as an "Orphan Drug" under the Orphan Drug Act of 1983 (the "Orphan Drug Act"),
which provides the Company with a seven year period of market exclusivity in the
United States from the date of the FDA approval. See "Government Regulation."

          In 1990, the Company was granted approval by the Irish National Drugs
Advisory Board to market PROAMATINE for use in the treatment of orthostatic
hypotension in Ireland, where the drug is sold under the name MIDON(R). In 1991,
the Company obtained regulatory approval for the sale in Canada of PROAMATINE
for use in the treatment of orthostatic hypotension, where the drug is sold
under the name AMATINE(R). AMATINE is sold in Canada by the Company's licensee,
Knoll Pharma Inc. ("Knoll") (formerly Boots Pharmaceuticals Ltd.). In December
1997, the Company filed an

                                      -3-
<PAGE>
 
application in the United Kingdom for the approval to market PROAMATINE
under the name MIDON(R) for the treatment of orthostatic hypotension.

          AGRYLIN(TM).  In 1991, the Company obtained an exclusive worldwide
license from Bristol-Myers Squibb to develop, market and sell AGRYLIN
(anagrelide), which has been developed as an oral treatment for thrombocytosis,
a blood disorder characterized by high blood platelet counts which could result
in an abnormally high incidence of adverse blood clotting events, including
heart attack and stroke. There is evidence that some patients with increased
platelet counts have thrombosis or hemorrhage which can be treated successfully
by lowering the platelet count. AGRYLIN is intended to inhibit excessive
platelet production and reduce the morbidity and mortality of heart attack and
stroke in thrombocytosis patients.

          In March 1997, the Company received notification from the FDA that the
Company's NDA for AGRYLIN was approved. The Company commenced active marketing
and sales activities with respect to AGRYLIN in the second quarter of 1997.
There is no other FDA approved treatment available for thrombocytosis. Other
current therapies used to reduce excessive platelet production have distinct
disadvantages, such as leukemogenesis, leukopenia and anemia. Further, AGRYLIN
has been designated by the FDA as an Orphan Drug. In December 1997, the Company
filed an application with the FDA to expand the indications of AGRYLIN to
include polycythemia vera.

          The Company has received approval of its New Drug Submission ("NDS")
from the Health Protection Branch, Canada ("HPB") for the sale of AGRYLIN
in the Canadian market, and has begun marketing the drug in Canada.

          AGRYLIN is currently in registration in Europe.  AGRYLIN has been
accepted by the European Community regulatory authorities as a "List B" product,
which includes those products considered to be major therapeutic advances. The
Company has filed a Product License Application with the European Medicines
Evaluation Agency ("EMEA") according to the EMEA harmonization procedures for
the approval of new drugs within the European Community. If approved by the
EMEA, AGRYLIN would receive simultaneous approval throughout the European
Community for sale in member countries. The Company also intends to pursue
filing in other geographic locations such as Japan, Australasia and Latin
America for the sale of AGRYLIN.

          PRESCRIPTION PHARMACEUTICAL PRODUCTS

          In addition to developing its proprietary pipeline products, the
Company's principal objective is to concentrate its operations primarily on
licensing, acquiring, developing, marketing and selling prescription
pharmaceutical products. To enhance the Company's presence in its targeted
therapeutic categories, the Company has acquired marketed prescription
pharmaceutical products

                                      -4-
<PAGE>
 
from various pharmaceutical companies. These product lines generate cash flow,
which contributes partial financial support to the Company's drug development
activities, and provides enhanced product sales opportunities for the Company's
sales force. Further, the sale of prescription pharmaceutical products has
enabled the Company to establish marketing channels in its targeted therapeutic
categories which the Company uses to market PROAMATINE and AGRYLIN and expects
to use to market its other late-stage development products if such products are
approved for sale.

          Over the last five years, the Company has acquired the United States
and/or foreign product rights for many prescription pharmaceutical products from
various pharmaceutical manufacturers such as Procter & Gamble Pharmaceuticals,
Inc. ("Procter & Gamble"), Bristol-Myers Squibb Company ("Bristol-Myers
Squibb"), Glaxo Canada, Inc. ("Glaxo Canada"), Du Pont Merck Pharmaceutical
Company ("Du Pont Merck"), Merck and Co., Inc. ("Merck"), G.D. Searle & Co.
("G.D. Searle"), SmithKline Beecham plc ("SmithKline Beecham") and Wyeth
Laboratories, U.K. Certain of these products are: NOROXIN(R), an antibiotic used
for the treatment of urinary tract infections; TIGAN(R), a drug used to control
nausea and vomiting; EMINASE(R), a thrombolytic agent used in the treatment of
acute myocardial infarction to dissolve blood clots obstructing coronary
arteries; ETHMOZINE(R), NORPACE(R), TRANDATE(R), SALUTENSIN(R), SALURON(R) and
NITRODISC, cardiovascular products; FLORINEF(R), for adrenocortical
insufficiency; MAXOLON(R), a gastro-intestinal agent used for treatment of
nausea and vomiting associated with cancer chemotherapy; MINTEC(R), a gastro-
intestinal drug used for symptomatic relief of irritable bowel and spastic colon
syndromes in adults; ESTRACE(R), a line of estrogen replacement therapy products
used for symptomatic relief of menopausal symptoms and for the prevention of
osteoporosis; and MEPTID(R) and LODINE(R), analgesic agents.

          As part of the Company's divestiture activities, the Company completed
the sale of NORETHIN, an oral contraceptive, to G.D. Searle in December,
1997.

          NONPRESCRIPTION PHARMACEUTICAL PRODUCTS

          In order to facilitate the growth of the Company's business, the
Company had always focused a part of its operations on the acquisition,
marketing and sale of nonprescription pharmaceutical products. Some of the
nonprescription pharmaceutical products acquired from various pharmaceutical
companies and which are marketed by the Company are CHERACOL D(R) and CHERACOL
PLUS(R), cough/cold products; COLACE(R), PERI-COLACE(R), SQUIBB(R) mineral oil,
SQUIBB(R) Glycerin Suppositories and SQUIBB(R) Cod Liver Oil, used in the
treatment of gastrointestinal disorders, and SLOW-MAG(R), a magnesium
supplement.

          In August 1995, the Company identified the sale of nonprescription
pharmaceuticals as a non-core business activity and made the decision to
divest most of the products it had acquired.

                                      -5-
<PAGE>
 
The Company divested a substantial portion of its nonprescription products
during 1996. The Company has retained and will continue to sell, and under the
right circumstances may acquire, only certain well known, high volume
nonprescription pharmaceutical products, such as COLACE, PERI-COLACE, and SLOW-
MAG, that do not require significant promotional outlays to establish and
maintain consumer brand recognition and the demand for which is not susceptible
to uncontrollable seasonal factors.

          LATE-STAGE DEVELOPMENT PRODUCTS

          The Company has a portfolio of several late-stage development
products, including PROAMATINE which, in addition to the treatment of
orthostatic hypotension for which it has received FDA approval, is being
developed for the treatment of stress urinary incontinence. Rights to these 
late-stage development products were acquired by the Company after substantial
value had been added to the products through research activities conducted by
others. The Company's objective is to continue the development of these late-
stage products and bring them to market as has been accomplished with PROAMATINE
and AGRYLIN. There can be no assurance that regulatory approval of the late-
stage developmental products will be obtained in the United States or abroad.
The Company intends to contract-out the development of several of its late stage
development products, utilizing contract clinical research organizations. Sales
of products acquired from other pharmaceutical companies, and sales of the
Company's prescription and nonprescription pharmaceutical products, have enabled
the Company to develop a marketing and sales infrastructure to facilitate sales
of these late-stage products, if approved.

          THERAPEUTIC CATEGORY - GASTROENTEROLOGY

          In the latter part of 1996, the Company and Eli Lilly and Company
("Lilly") entered into a series of License Agreements pursuant to which the
Company acquired from Lilly certain rights to four developmental compounds
designated LY246736, LY353433, LY213829 (also known as "Tazofelone") and
LY315535 (collectively, the "Compounds"), which could potentially address some
of the unmet medical needs with respect to certain gastrointestinal disorders
such as inflammatory bowel disease and irritable bowel syndrome. Each of the
License Agreements grants the Company an exclusive license to develop,
manufacture, market and sell the Compounds anywhere in the world, except with
respect to LY315535, for which the Company is licensed only in the United States
and its territories, Canada and Mexico. For a description of certain other terms
of the Lilly License Agreements, see "License Agreements."

          Tazofelone is being developed for the treatment of Inflammatory Bowel
Diseases ("IBD"), including ulcerative colitis and Crohn's disease. A Phase II
efficacy trial has been completed for Tazofelone, and Tazofelone could offer
consumers an alternative to existing treatments for IBD which include
corticosteroids, 5ASA and azsulfidine.

                                      -6-
<PAGE>
 
          The other three Compounds are being developed to treat Functional
Bowel Disorders ("FBD"), including irritable bowel syndrome and non-ulcerative
dyspepsia. These Compounds could provide an alternative to current FBD therapies
which include dietary changes, over-the-counter laxatives, antidiarrheals,
prescription antispasmodics, gastroprokinetics, proton pump inhibitors, 5HT\3\
compounds and antacids.

          The Company has completed a Phase 1a study of LY315535.  The compound
is being developed for the treatment of irritable bowel syndrome and non-ulcer
dyspepsia. The Phase 1a single rising dose study was conducted in human
volunteers. The objectives of the placebo-controlled study were to 1) show
safety across a range of doses and 2) establish a maximum tolerated dose. The
study demonstrated a favorable safety profile with LY315535 being well-tolerated
across a broad range of doses. Given the positive outcome of this study, the
next stage of Phase I testing in humans is scheduled to commence in the near
term.

          THERAPEUTIC CATEGORY - CARDIOVASCULAR

          In March 1997, the Company and Pfizer Inc. ("Pfizer") entered into a
License Agreement pursuant to which the Company acquired from Pfizer worldwide
rights to a compound in development called Sampatrilat. Sampatrilat, currently
in phase II clinical trials, is intended to treat essential hypertension and
congestive heart failure. The License Agreement grants the Company exclusive
worldwide rights to develop, manufacture, market and sell Sampatrilat anywhere
in the world.

          Sampatrilat incorporates, in a single substance, two different but
complimentary modes of activity. It is a potent inhibitor of angiotensin
converting enzyme ("ACE") and also inhibits neutral endopeptidase which, in
turn, results in an elevation of atrial natriuretic factor ("ANF"), the body's
own natural diuretic. This dual mode of activity may offer patients and managed
care providers the potential advantages of a treatment regime involving fewer
drugs, reduced risks, and lower costs in comparison to currently existing
therapies.

          Today, treatment of uncomplicated essential hypertension follows a
step therapy paradigm with the initial treatment often being an ACE inhibitor.
However, normalization of blood pressure may require the addition of a second
drug, generally a diuretic, in combination with the ACE inhibitor. This type of
step therapy, involving two and sometimes three drugs, may produce side effects
comprising the additive adverse reactions of the different products employed.

          Diuretics commonly employed with ACE inhibitors can produce side
effects that include potassium depletion, gout, elevated blood lipids, and
abnormalities in sugar metabolism. Because ANF is a natural diuretic that does
not possess these properties, the use of Sampatrilat in hypertension or
congestive heart failure patients

                                      -7-
<PAGE>
 
may confer, through the administration of a single drug, all the advantages of a
pure ACE inhibitor with the addition of greater natruresis thus obviating the
separate diuretics.

          THERAPEUTIC CATEGORY - RESPIRATORY

          MAXIVENT(R).  In 1984, the Company obtained an exclusive license from
ABC Laboratories of Italy ("ABC") to develop and market MAXIVENT (doxofylline)
in the United States, Canada and Japan and, in 1989, obtained a nonexclusive
license to develop and market the drug in the United Kingdom and Ireland.
MAXIVENT is an oral bronchodilator intended for use in the treatment of asthma.

          Common asthma is a condition involving the periodic constriction of
the airways resulting in labored and often painful breathing. Treatment is
generally provided by means of bronchodilator drugs which relieve the
constriction of the airways and, in turn, the distress of an attack. The most
commonly used oral bronchodilator is theophylline, a drug with good efficacy but
which is capable of producing certain undesirable side effects such as
disturbances in heart rhythm, central nervous system irritability, convulsions,
gastro-intestinal distress and excess urination. Phase II clinical studies and
Phase III clinical trials indicate that MAXIVENT appears to be comparable in
efficacy to theophylline; however, unlike theophylline, MAXIVENT does not appear
to produce a high incidence of adverse side effects.

          The Company has completed Phase III trials and is reviewing various
alternatives for commercialization of this compound, including the outlicensing
thereof. MAXIVENT has been approved for commercial sale in Italy and is
currently being sold in that country under the tradename "ANSIMAR" by the
Company's unaffiliated licensor, ABC.

          THERAPEUTIC CATEGORY - GYNECOLOGY/ENDOCRINOLOGY

          SOMAGARD(R).  In 1988, the Company acquired rights from the Salk
Institute to manufacture and market SOMAGARD (deslorelin) in the United States
and in certain foreign countries, including the United Kingdom and Canada.
SOMAGARD is being developed for the treatment of central precocious puberty in
children, an endocrine disorder that results in premature release of hormones,
and endometriosis in women. Published reports of long-term studies conducted by
the National Institutes of Health have indicated that the administration of
SOMAGARD inhibits the release of hormones which cause the abnormal maturation
process and causes a return to normal growth rates. The Company has completed
Phase III trials for SOMAGARD for use in the treatment of central precocious
puberty and is studying various alternatives for the commercialization of this
product and may elect to complete its development through a licensing
arrangement with a third party.

          The Company currently markets the product SUPPRELIN(R) (histrelin), an
Orphan Drug, for central precocious puberty.  See

                                      -8-
<PAGE>
 
"Government Regulation." The Company believes that SOMAGARD will complement
SUPPRELIN. SOMAGARD, if approved by the FDA, would be marketed to
endocrinologists and managed healthcare organizations.

          SOMAGARD also is being developed as a treatment for endometriosis.  A
number of Phase II clinical trials for this indication have been conducted.
Endometriosis is a gynecologic abnormality which may result in pain, infertility
and sexual and bowel dysfunction. Published reports of studies conducted by the
National Institutes of Health indicate that SOMAGARD relieves pain and restores
normal sexual and bowel function in women with this condition .

          THERAPEUTIC CATEGORY - HEMATOLOGY

          STANATE(TM).  In 1994, the Company acquired the exclusive worldwide
rights from The Rockefeller University to develop, manufacture, market and sell
STANATE (stannsoporfin), which is being developed for the treatment of
hyperbilirubinemia in neonates, a condition caused by an accumulation of
excessive levels of bilirubin produced by the liver. Unless treated,
hyperbilirubinemia can result in jaundice, brain damage and death.

          Bilirubin is excreted by the liver pursuant to a metabolic step
requiring the presence of an enzyme which, studies have shown, is not fully
functional in many early term and full term neonates. STANATE is intended to
inhibit the accumulation of excessive levels of bilirubin in neonates and to
provide neonate enzyme systems with an opportunity to mature and take over the
normal elimination of bilirubin.

          The most common treatment for hyperbilirubinemia in neonates involves
phototherapy which requires exposure to a light source in order to stimulate the
temporary excretion of bilirubin by the kidneys. Phototherapy is often not fully
effective and requires many hours and sometimes several days of exposure to
light with resulting maternal separation, extensive nursing supervision and
related time-sensitive costs. In contrast, STANATE is administered by injection
and clinical studies have shown that one dose is generally all that is necessary
for treatment purposes. STANATE is currently in Phase II/III clinical trials .

          THERAPEUTIC CATEGORY - UROLOGY

          PROAMATINE.  In addition to its use in the treatment of blood pressure
disorders, PROAMATINE is currently sold in several countries by unaffiliated
third parties to treat stress urinary incontinence, the involuntary loss of
urine from the bladder. There is no approved therapy for stress urinary
incontinence in the United States. PROAMATINE is an alpha agonist which
increases the tension of the urinary sphincter, thereby preventing the
involuntary loss of urine from the bladder. The Company is conducting a Phase II
clinical program in the United States for the use of PROAMATINE in the treatment
of stress urinary incontinence.

          THERAPEUTIC CATEGORY - ONCOLOGY

          RADINYL.  In 1985, the Company obtained from the United States
government rights to manufacture and sell the product RADINYL (etanidazole), a
radiosensitizer being developed to enhance the anticancer effects of radiation
therapy and a chemosensitizer being developed to increase the effectiveness of
other anticancer drugs.

          For use in conjunction with radiotherapy, RADINYL is currently in
Phase III clinical trials in patients with advanced head and neck cancer. The
patients enrolled in these trials in the United States and Europe were
randomized to receive either RADINYL in conjunction with radiotherapy or
radiotherapy alone. The results of these studies are currently under analysis.

          Phase I and Phase II clinical studies are being conducted with RADINYL
to determine its potential in increasing the effectiveness of other anticancer
drugs in the treatment of brain, lung, prostate and bladder cancer and its
potential for use with brachytherapy, a technique involving the direct implant
of a radioactive source into or adjacent to large tumors.

          DIRAME(R).  In 1992, the Company obtained exclusive worldwide rights
from Bayer AG ("Bayer") to develop and market DIRAME (propiram), a potent,
centrally acting analgesic with low addiction potential intended for use in the
control of moderate to severe acute or chronic pain. See "Government
Regulation."

          DIRAME is in Phase III clinical trials which indicate that the
compound appears to be safe and effective in patients with various kinds of
acute and chronic pain.

          A joint venture from which Bayer obtained the rights to DIRAME had
initially filed an NDA for DIRAME. Subsequent to such filing, the FDA required
additional studies regarding the drug. The Company is now addressing the issues
raised by the FDA and, in 1993, commenced long-term carcinogenicity studies on
two species of laboratory animals and other clinical studies. The in-life phase
of these studies has been completed and the results are currently under
analysis. In order to complete its NDA filing the Company believes it must
complete an additional Phase III clinical trial. The Company plans to commence
such clinical trial during 1998.

          SOMAGARD.  In addition to the treatment of central precocious puberty
and endometriosis, SOMAGARD has been studied as adjunctive treatment for
prostate cancer. Other treatments for prostate cancer such as surgery and/or
radiotherapy are often precluded because the cancer has spread to the bones. As
a result, castration, hormonal therapy or chemotherapy are often the only
available treatments. SOMAGARD is being evaluated by the Company as an
alternative to these procedures. The Company has filed a Product License
Application (NDA equivalent) for SOMAGARD for treatment of prostate cancer in
the United Kingdom and has obtained approval from the Irish regulatory
authorities to market the

                                      -10-
<PAGE>
 
product for this indication.  Use of SOMAGARD for the treatment of prostate
cancer in the United States is in Phase III clinical trials.

          LICENSE AGREEMENTS

          The Company has obtained rights to the late-stage drugs currently
being developed by it through license agreements with pharmaceutical companies,
government agencies and research-based institutions and has sublicensed certain
of these rights to pharmaceutical companies through license and/or marketing
agreements. A discussion of these agreements is provided below.

          PROAMATINE Agreements.  In 1985, the Company entered into a license
          ----------------------                                             
agreement with the predecessor in interest of Nycomed Pharma pursuant to which
the Company obtained exclusive rights to develop and market the product
PROAMATINE in the United States, Canada, the United Kingdom, Ireland and certain
other countries. The agreement was amended in January 1994 to, among other
things, provide for a reduction in the delivery price of the product to the
Company in any territory covered by the agreement for a five year period
commencing upon the Company's launch of the product in any such territory and
the addition of minimum sales requirements which must be achieved by the Company
in the territories covered by the agreement in order to maintain exclusivity.
The Company's agreement with Nycomed Pharma, as amended, obligates it to develop
PROAMATINE and obtain governmental approval to market the product in the
licensed territories. The Company is obliged to pay a royalty to Nycomed Pharma
on sales of PROAMATINE by the Company and its distributors and must purchase its
requirements of PROAMATINE from Nycomed Pharma.

          In 1991, the Company entered into a marketing agreement with Knoll
which granted Knoll the exclusive right to market and sell PROAMATINE in Canada
(under the name AMATINE) for use in the treatment of orthostatic hypotension.

          AGRYLIN Agreements.  In 1991, the Company entered into a license
          -------------------                                             
agreement with Bristol-Myers Squibb pursuant to which the Company obtained
exclusive worldwide rights to develop and market AGRYLIN. The Company is obliged
to fund the continued development and registration of AGRYLIN, made a payment
upon FDA approval and paid and will continue to pay royalties on sales of the
drug.

          The Company entered into various distribution agreements with third
parties for the distribution and sale of AGRYLIN in Norway, Sweden, Finland,
Denmark, Iceland, Israel, Australia and New Zealand. AGRYLIN is not yet approved
in these countries and, as part of the distribution agreement, the distributors
are responsible for obtaining regulatory approval. If regulatory approval is
obtained, the Company will supply finished goods to the distributors which will
provide physical distribution along with marketing and sales support.


                                      -11-
<PAGE>
 
          MAXIVENT Agreements.  In 1984, the Company obtained an exclusive
          --------------------                                            
license from ABC to develop and market MAXIVENT in the United States, Canada and
Japan and, in 1989, obtained a nonexclusive license to develop and market the
drug in the United Kingdom and Ireland. The exclusive license agreement requires
the Company to develop the product and obtain the requisite FDA and other
approvals. Each of the exclusive and nonexclusive license agreements requires
the Company to purchase its requirements of the bulk drug substance from ABC. If
the Company does not meet certain sales levels to be agreed upon, ABC may
terminate the exclusive license agreement, appoint additional licensees in the
United States, Canada and Japan or market the product directly or through third
parties in the United Kingdom and Ireland.

          SOMAGARD License Agreement.  In 1988, the Company and the Salk
          ---------------------------                                   
Institute entered into a license agreement pursuant to which the Company
obtained certain rights to develop and market the product SOMAGARD in the United
States and certain foreign markets, including the United Kingdom and Canada.
Under the terms of the license agreement, the Company is required to pay
royalties on sales of SOMAGARD in countries in which the Salk Institute has
obtained patents.

          DIRAME License Agreement.  In 1992, the Company entered into a license
          -------------------------                                             
agreement with Bayer with respect to the product DIRAME. Pursuant to this
agreement, the Company acquired exclusive worldwide rights from Bayer to
develop, manufacture and market the product DIRAME. The Company paid an up-front
royalty to Bayer for rights to develop and market DIRAME. The Company must also
pay Bayer licensing fees and royalties on sales.

          RADINYL Agreements.  In 1985, the United States government and the
          -------------------                                               
Company entered into a license agreement pursuant to which the Company obtained
certain rights to develop and market the product RADINYL. The license granted to
the Company is exclusive for seven years from the date of the first commercial
sale of the product and nonexclusive thereafter. The agreement pursuant to which
the license has been granted requires the Company to pay certain patent
maintenance fees and royalties to the United States government.

          In 1985, the Company and the predecessor in interest of Nycomed Pharma
formed a joint venture company known as Linz-Roberts, Inc. ("Linz-Roberts") to
develop RADINYL. The Company and Nycomed Pharma each owns 50% of the common
stock of Linz-Roberts. The Company contributed its license to RADINYL to Linz-
Roberts and the Company has been granted an exclusive license by the joint
venture to manufacture and distribute RADINYL dosage forms in the United States,
Canada, the United Kingdom and Ireland. Nycomed Pharma has been licensed on an
exclusive basis to manufacture and distribute RADINYL dosage forms in Europe
(except the United Kingdom and Ireland), the Middle East and Africa. Both
parties have the right to grant sublicenses. Nycomed Pharma has been designated
the supplier of bulk RADINYL substance, and the joint venture has contracted to
purchase its entire requirements of

                                      -12-
<PAGE>
 
bulk RADINYL substance from Nycomed Pharma, provided that Nycomed Pharma can
meet certain price requirements and supply all required quantities. Linz-Roberts
has retained the right to distribute RADINYL in the territories not licensed to
the Company or Nycomed Pharma.

          STANATE License Agreement.  In 1994, the Company and The Rockefeller
          --------------------------                                          
University entered into a license agreement pursuant to which the Company
acquired the exclusive worldwide rights to develop, manufacture, market and sell
STANATE. The Company paid an up-front license fee to Rockefeller University for
the rights to develop, manufacture, market and sell STANATE. The Company must
also pay Rockefeller University annual licensing fees and royalties on sales.

          License Agreements for TAZOFELONE and other Lilly Compounds. In 1996,
          ------------------------------------------------------------         
the Company entered into four License Agreements with Lilly pursuant to which
the Company acquired the exclusive rights to develop, manufacture, market and
sell Tazofelone and the Compounds LY246736 and LY353433 anywhere in the world
and the Compound LY315535 in the United States and its territories, Canada and
Mexico. The term of each of the License Agreements shall be the later of either
(i) the life of the last to expire of the patents covering a Compound or (ii)
fifteen years. Under the terms of each of the License Agreements, the Company
paid Lilly a signing fee and is obligated to make certain milestone payments to
Lilly as well as pay Lilly certain royalties based on the sales of any products
resulting from the Compounds.

          SAMPATRILAT License Agreement.  In March, 1997, the Company entered
          ------------------------------                                     
into a License Agreement with Pfizer pursuant to which the Company acquired the
exclusive rights to develop, manufacture, market and sell Sampatrilat anywhere
in the world. The term of the License Agreement shall be the earlier of the
expiration of the last to expire of the patents covering Sampatrilat or fifteen
years from the date of first commercial sale of a product containing
Sampatrilat. Under the terms of the License Agreement, the Company paid Pfizer a
signing fee and is obligated to make certain milestone payments as well as pay
Pfizer certain royalties based on the sale of products containing Sampatrilat.
Pfizer has retained the right under certain circumstances should the Company's
sales of Sampatrilat dosage forms equal or exceed a certain percentage of the
worldwide sales of pharmaceuticals sold for the treatment of hypertension in
humans, to convert the Company's license to a non-exclusive license upon the
making of certain payments to the Company.

          MARKETING

          In the United States, the Company markets and sells its products
primarily through its own sales force and through a network of brokers and
distributors. The Company has positioned its sales operation to impact selected
physician specialties and major buying and decision making entities, such as
managed care

                                      -13-
<PAGE>
 
organizations and large retail and mass merchandise operations. With the growing
trend in the United States of providing health care through some form of managed
care program, the Company has stepped-up its selling efforts of prescription
products to such managed healthcare organizations. In an effort to increase its
sales to managed healthcare organizations, the Company has employed national
account managers to focus efforts on this growing market. Various marketing,
promotion, sales and training programs have been initiated to improve the
Company's penetration of the managed healthcare market and increase product
sales to managed healthcare organizations.

          MANUFACTURING

          From its inception, the Company's initial strategy was to outsource
its manufacturing and packaging functions in order to enable the Company to grow
without requiring large capital outlays to produce and package its products. In
that regard, the Company has engaged contractors, primarily large pharmaceutical
companies, to convert active ingredients into finished drug products. In most
instances where the Company has acquired the rights to approved products from
other pharmaceutical companies, the seller or licensor has agreed to manufacture
the Company's requirements of the products for a specified period of time. The
manufacturing activities conducted by third parties for the Company have
consisted of the receipt and storage of materials, purification, production,
packaging and labeling. The Company maintains a manufacturing department which
is responsible for (i) monitoring the manufacturing operations of its
contractors, (ii) inventory control, and (iii) quality control. The Company's
manufacturing department maintains a quality control and quality assurance
program, including a set of standard operating procedures, designed to assure
that the Company's products are manufactured in accordance with Good
Manufacturing Practices standards ("GMP") and other applicable domestic and
foreign regulations.

          The Company has determined that it will take control of a major
portion of its manufacturing activities and seek to achieve certain cost
efficiencies. In July, 1997, the Company concluded the purchase from Monsanto
Canada, Inc. of a 100,000 square foot pharmaceutical manufacturing facility
previously operated by Monsanto's Searle Division ("Searle") located in
Oakville, Ontario, Canada. The facility is approved by both the FDA and HPB. In
addition to manufacturing and processing capabilities, the facility includes
laboratory, warehouse and administrative space. The Company has begun
transferring certain product packaging from third parties to this facility, and
should realize certain benefits, including, without limitation, lower production
costs and more flexibility in determining appropriate inventory levels for the
Company's products when it begins to transfer the manufacturing of certain
products to this facility upon appropriate regulatory approval. In addition, the
Company utilized the available office space in Oakville by relocating the
operations of its subsidiary, Roberts Pharmaceutical Canada, Inc., to the
Oakville facility. The Company's ability to transfer the production of certain
of its products to the Oakville facility will be, in certain cases, dependent on
the duration of its current agreements with suppliers,

                                      -14-
<PAGE>
 
and the ability to obtain regulatory approvals to transfer the manufacture
of these products to Oakville.

          The Company is currently in the process of refitting the Oakville
plant in order to accommodate the manufacture of as many of the Company's
products as possible. In addition, the Company will explore the possibility of
using the Oakville facility to engage in contract manufacturing for other
pharmaceutical companies.

          DISTRIBUTION

          In October 1997, the Company completed the acquisition of an
approximately 70,000 square foot distribution facility located in a suburb of
Chicago. The Company anticipates that it will begin distributing its products
from this facility in the second quarter, 1998. The Company anticipates that its
distribution costs will decrease as a result of the acquisition of its own
distribution facility.

          HOMECARE

          In August 1995, the Company announced its decision to discontinue and
divest certain non-core, nonpharmaceutical business activities, including the
operations of Homecare, which were no longer compatible with the Company's
objective of growing and developing a pharmaceutical company with a primary
focus on the sale of prescription drugs. Through Homecare, the Company
distributed high value prescription injectable and biotechnology pharmaceutical
products for physician office use and provided medical and other health oriented
therapies in home and outpatient settings. While Homecare's businesses had a
role in the initial stages of the Company's growth and development, those
businesses never represented a significant portion of the Company's consolidated
revenue or earnings. The Company has completely divested the Homecare operations
located in New Jersey, North Carolina and South Carolina. The entity which
purchased the New Jersey operations has also executed an agreement with the
Company to purchase Homecare's New York operations. The final consummation of
such agreement is pending as the purchasers seek state regulatory approval to
finalize the transaction. See "Notes to Consolidated Financial Statements - Note
14."

          CONTRACT CLINICAL RESEARCH

          Since its inception, the Company, through its subsidiary VRG
International, Inc. ("VRG"), has derived a portion of its revenues from contract
clinical research. Under these arrangements, the Company is paid a fee to
conduct clinical research for pharmaceutical companies that wish to test the
safety and efficacy of their products. The Company has primarily conducted
studies of investigational new drugs for major multinational pharmaceutical
company clients and to a lesser degree performed safety and efficacy tests on a
variety of over-the-counter products. The

                                      -15-
<PAGE>
 
Company has also provided clinical investigation services to pharmaceutical
companies to assist them in reducing the time required to introduce new drugs to
the market.

          The Company's integrated clinical research operations have been
conducted through twelve research-dedicated outpatient clinics located
throughout the U.S.; an in-house patient recruiting system; a custom designed
multi-purpose computerized study tracking system; on-site study coordinators;
qualified contract investigators; sophisticated data management and multi-level
quality control.

          Consistent with the Company's decision in 1995 to discontinue and
divest certain of its non-core, nonpharmaceutical businesses, the Company
announced, in March 1996, its intentions to discontinue and divest the business
operations of VRG. Contract clinical research generally has proven to have lower
profit margins than the sale of prescription pharmaceuticals, and the Company
believes that, in the future, contract clinical research has lower growth
prospects for it than the sale of prescription pharmaceuticals. In January,
1998, the Company signed a Letter of Intent to sell VRG's operations subject to
the execution of a definitive acquisition agreement and the successful
completion of due diligence by the purchaser. To date, the Company and the
purchaser are negotiating the terms of said definitive acquisition agreement and
the transaction is expected to close within the month of April, 1998. See "Item
7 Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Notes to Consolidated Financial Statements - Note 14."

          PATENTS AND PROPRIETARY RIGHTS

          The Company considers the protection of discoveries in connection with
its development activities important to its business. To date, the Company has
acquired certain patents in connection with the acquisition of certain products
and has filed applications for patents covering new processes for manufacturing
anagrelide, the active ingredient in AGRYLIN. Additionally, rights to patented
technology have been licensed to the Company. The late-stage products being
developed by the Company which are afforded patent protection are: AGRYLIN -
patents issued 1982 and applications filed in 1996; RADINYL - patent issued
1983; STANATE -patents issued 1987, 1988, 1992 and 1993. Also, regarding the
Compounds acquired from Lilly, certain patents have been issued in the United
States and several other countries with respect to Tazofelone and the Compound
designated LY246736. In addition, there are other domestic or foreign patent
applications pending for all of the Compounds. Patents have been issued with
respect to the compound Sampatrilat, licensed from Pfizer. Certain of the
Company's products may be afforded protection under laws which provide market
exclusivity for Orphan Drugs and drugs which include a new active ingredient.
See "Government Regulation."


                                      -16-

          COMPETITION

          Many companies, including large pharmaceutical, chemical and
biotechnology firms with financial and marketing resources and research and
development staffs and facilities substantially greater than those of the
Company, are engaged in researching, developing, marketing and selling products
intended to treat the same conditions and diseases as the products currently
sold and under development by the Company. Further, other products now in use or
under development by others may be intended to treat the same conditions as the
Company's products. The pharmaceutical industry is characterized by rapid
technological advances, and competitors may develop products more rapidly than
the Company. In addition, competitors may be able to complete the regulatory
approval process sooner than the Company, and therefore market their products
earlier than the Company can market certain of its products.

          GOVERNMENT REGULATION

          The marketing of pharmaceutical products requires the approval of the
FDA and comparable agencies in foreign countries. The FDA has established
guidelines and safety standards which apply to the preclinical evaluation,
clinical testing, manufacture and marketing of pharmaceutical products. The
process of obtaining FDA approval for a new drug can take many years and
involves the expenditure of substantial resources. The steps required before
such a product can be produced and marketed for human use include preclinical
studies, the filing of an IND, human clinical trials and the approval of an NDA.

          Drug marketing exclusivity protection is granted through the Orphan
Drug Act of 1983 (the "Orphan Drug Act") and the Drug Price Competition and
Patent Term Restoration Act of 1984 (commonly referred to as the "Waxman Hatch
Act"). The Orphan Drug Act entitles a company to market exclusivity in the
United States for a period of seven years from the date of FDA approval for
drugs which, among other criteria, are intended to treat a patient population of
less than 200,000. PROAMATINE for idiopathic orthostatic hypotension and AGRYLIN
for thrombocythemia have been granted Orphan Drug status by the FDA. Certain
provisions of the Waxman-Hatch Act grant market exclusivity in the United States
for a period of five years from the date of FDA approval for drugs containing a
new active ingredient. Based upon its review of industry and government data,
the Company believes that DIRAME may qualify for this protection.

          The manufacturing processes of the Company and its contractors and
licensors are subject to regulation, including the need to comply with Good
Manufacturing Practices. These same regulations will apply to the Company with
respect to the Oakville, Ontario manufacturing facility which it has purchased
from Searle. See "Manufacturing." The Company's business is also subject to
regulation under the Occupational Safety and Health Act, the


                                      -17-
<PAGE>
 
Environmental Protection Act, the Toxic Substances Control Act, the Drug
Enforcement Act, the Resource Conservation and Recovery Act, the Pharmaceutical
Marketing Act of 1988 and other current and potential future federal, state or
local regulations.

          The Company markets various products containing controlled substances
that are subject to the Department of Justice, Drug Enforcement Administration
regulations. Distribution of prescription drugs classified as controlled
substances or, in some cases, other pharmaceutical products, is subject to
licensing or regulation in certain states. Generally, the entity engaged in the
actual distribution is subject to such regulation. In addition, state licensing
is generally required in the state in which such entity's principal place of
business is located.

          United States Federal and state governments continue to seek means to
reduce costs of Medicare and Medicaid programs, including placement of
restrictions on reimbursement for, or access to, certain drug products. Major
changes were made in the Medicaid program under the Omnibus Budget
Reconciliation Act of 1990 (the "Act"). As a result, the Company entered into a
Medicaid Rebate Agreement ("Rebate Agreement") with the United States
Government, under Section 4401 of the Act. Pursuant to the Rebate Agreement, in
order for federal reimbursement to be available for prescription drugs under
state Medicaid plans, the Company must pay certain statutorily prescribed
rebates on Medicaid purchases. Effective July 1, 1991, the law also denies
federal Medicaid reimbursement for drug products of the original NDA-holder if a
less expensive generic version of such drug is available from another
manufacturer, unless the prescriber indicates on the prescription that the
branded product is medically necessary.

          In most other markets, governments exert controls over pharmaceutical
prices either directly or by controlling admission to, or levels for,
reimbursement by government health programs. The nature of such controls and
their effect on the pharmaceutical industry vary greatly from country to
country.

          EMPLOYEES

          As of March 20, 1998, the Company had 498 employees, including 5
officers, 81 persons engaged in research and development activities and 215
persons engaged in marketing and sales activities. In addition to its full-time
staff, the Company engages medical doctors and other professional personnel on a
consultancy basis and, from time to time, consultants and others on a per diem
or hourly basis. The Company believes its relations with its employees are
satisfactory.

          FINANCIAL INFORMATION ABOUT FOREIGN AND DOMESTIC OPERATIONS

          Financial Information about Foreign and Domestic Operations is
presented in Note 13 to the Company's financial statements. See "Notes to

ITEM 2.  PROPERTIES

          The Company's worldwide headquarters are located at Meridian Center
II, 4 Industrial Way West, Eatontown, New Jersey. The building housing the
Company's worldwide headquarters, which was purchased by the Company in 1992 and
occupied in 1993, consists of an aggregate of 80,000 square feet.

          The Company owns an office and warehouse building consisting of 30,300
square feet, which is located across the street from the Company's worldwide
headquarters. The Company uses this building for the warehousing of Company
records, archives, certain offices and facilities.

          The Company has purchased a 100,000 square foot manufacturing facility
located in Oakville, Ontario, Canada. The Company has purchased an approximately
70,000 square foot distribution center located in Buffalo Grove, Illinois, a
suburb of Chicago. See "Item 1 Business - Manufacturing; Distribution."

          The Company's United Kingdom subsidiary, Monmouth Pharmaceuticals,
Ltd., occupies 3,800 square feet of leased office space in the Surrey Research
Park in Guildford, Surrey, England, approximately 30 miles south of London. The
monthly rental for these offices is approximately 6,500 British pounds.

          The Company also leases office space in several other locations in the
United States.

ITEM 3.  LEGAL PROCEEDINGS

          On April 10, 1995, a shareholders' class action suit was instituted in
the United States District Court for the District of New Jersey against the
Company and certain of its officers and a former officer by Grace Cowitt
("Cowitt") on behalf of all persons who purchased shares of the Company's Common
stock between November 7, 1994 and March 22, 1995. The complaint asserted claims
against the Company and certain of its officers and a former officer for
violations of Sections 10(b) and 20(a) of the Securities and Exchange Act of
1934, as amended, and Rule 10b-5 promulgated thereunder with respect to press
releases and filings with the Securities and Exchange Commission and certain
public statements allegedly made by the Company and certain of its officers and
a former officer relating to the Company's business. The plaintiff sought to
recover damages in an unspecified amount. On June 26, 1995, a similar
shareholders' class action suit was instituted in the United States District
Court for the District of New Jersey against the Company and certain of its
officers and a former officer by Dieter Zander ("Zander") on behalf of all
persons who purchased shares of the Company's Common Stock between November 7,
1994 and May 31, 1995. This suit was voluntarily dismissed by Zander in October
1995. In August 1995, a consolidated complaint was filed in which the plaintiff,
Cowitt, extended the proposed class period from March 22, 1995 through May 31,
1995. The Company fully and finally settled this matter in January of 1998. See
"Notes to Consolidated Fiancial Statements - Note 11."

          There are no additional material legal, governmental, administrative
or other proceedings pending against the Company, any of its subsidiaries or any
of their properties, or to which the Company or any such subsidiary is a party,
and to the knowledge of management, no such material proceedings are threatened

/1/  Intangible Dispositions and Write-Offs.  During the fourth quarter of 1996,
     ---------------------------------------                                    
     the Company completed the sale of the majority of its non-core
     nonprescription products along with the NUCOFED and QUIBRON brands in two
     independent sales transactions.  These sales, net of proceeds, resulted in
     a one time, non-cash write off of $11.9 million, which amounted to $7.6
     million net of taxes.  Also, during the fourth quarter of 1996, the Company
     expensed certain purchased development products and recorded an impairment
     loss of long-lived intangible assets totalling $25.4 million, which
     amounted to $17.8 million net of taxes.

     Operating income and net loss were negatively affected by the purchase of
     development products and the sale and write down of the intangible assets
     in the amounts of $37.3 million for operating income and $25.4 million for
     net loss. In the event that these transactions had not occurred, the
     operating loss would have been $12.9 million and net loss would have been
     $8.3 million.

/2/  Pursuant to a position taken by the SEC staff (the "Staff"), effective
     March 13, 1997, on accounting for preferred stock which is convertible at a
     discount to market, the Company recorded a charge for Earnings Per Share
     purposes of $.61 per share.  This charge to Earnings Per Share is
     consistent with the Staff's position that the 10% discount available to
     holders of the Company's 5% Convertible Preferred Stock ("5% Preferred

                                      -25-
<PAGE>
 
     Stock") should be amortized between the issuance date and the first date
     that conversion could occur.

     To clarify the adjustments indicated above, a reconciliation of Earnings
     Per Share for the twelve months ended December 31, 1996 is composed of the
     following elements:

Net (loss) from continuing operations before the
    consideration of purchased research and development,
       write-off and the sale of intangible assets, the
       recognition of the discount upon the
    issuance of 5% Preferred Stock or preferred dividends            $ (.47)

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS

RESULTS OF OPERATIONS

YEARS ENDED DECEMBER 31, 1996 AND 1997

          Corporate Revenues.  For the year ended December 31, 1997, total
          -------------------                                             
revenue increased $24.4 million from $98.1 to $122.5 million. This increase was
the result of an increase in product sales.

          Product Sales.  For the year ended December 31, 1997, product sales
          --------------                                                     
increased $23.5 million from $98.1 to $121.6 million. This increase is primarily
the result of sales in the United States of AGRYLIN and PROAMATINE. AGRYLIN was
launched in the first quarter of 1997 and PROAMATINE was launched in the fourth
quarter of 1996. The COLACE line also contributed significant increases.

          For the year ended December 31, 1997, sales of the Company's United
Kingdom subsidiary, Monmouth Pharmaceuticals, Ltd., increased $5.5 million from
$12.0 million to $17.5 million. Increased sales of LODINE, launched in the
fourth quarter of 1996, are the primary reason for this increase. Product sales
of the Company's Canadian subsidiary, Roberts Pharmaceutical Canada, Inc.,
increased $0.8 million from $11.7 million to $12.5 million.

          Cost of Sales.  For the year ended December 31, 1997, cost of sales
          --------------                                                     
amounted to 42% of product sales as compared to 51% in 1996. This decrease in
cost of sales percentage and corresponding increase in gross profit percentage
is primarily the result of the addition of AGRYLIN to the product mix. AGRYLIN
has a higher gross profit percentage as it is a product the development of which
was completed internally.

          Research and Development.  Research and development expenses increased
          -------------------------                                             
$5.7 million from $7.4 million in 1996 to $13.1 million in 1997. Approximately
$1.6 million of this increase is due to the purchase of development-stage
products where the cost of acquisition is charged immediately to research and
development expense. Other reasons for the increase include a post-launch study
for PROAMATINE, the continued development of DIRAME, STANATE and the purchased
compounds, and increases in registration and user fees. The Company anticipates
research and development expenses will continue to increase in 1998 due to
potential purchases of development-stage drugs and the development of current
compounds.

          Marketing and Administrative Expenses.  Marketing and administrative
          --------------------------------------                              
expenses increased $1.5 million from $57.2 million

                                      -27-
<PAGE>
 
in 1996 to $58.7 million in 1997. Marketing expenses increased $0.5 million
primarily as a result of increased sampling, market research, the introduction
of AGRLYIN, and fleet expenses offset by decreases in outside services and
travel and meetings. Administrative expenses increased $1.0 million during 1997
as compared to 1996 in large part due to increases in salaries and benefits
offset by decreases in legal and accounting fees related to the shareholders'
class action lawsuit which was fully and finally settled in January 1998 and the
annual audit.

          Interest Income and Expense.  For the year ended December 31, 1997,
          ----------------------------                                       
interest income increased $2.3 million from $2.9 million to $5.2 million as the
result of an increased cash balance due to the private placements that were
completed during 1996. Interest expense decreased from $1.8 million in 1996 to
$0.8 million in 1997 as a result of a decrease in long-term debt related to
product acquisitions.

          Income Taxes.  For the year ended December 31, 1997, income taxes from
          -------------                                                         
continuing operations increased $13.5 million from a benefit of $14.6 million to
a benefit of $1.1 million, primarily as a result of improved 1997 operations
versus 1996 and a 1996 write off and disposition of certain intangible assets.
The Company's effective tax benefit of 77% was higher than the normal statutory
rate primarily as a result of the elimination of certain reserves for taxes due
to the closure of years 1991 through 1993 after an IRS audit.

          The Company has recorded net deferred tax assets of approximately
$17.3 million. Realization is dependent upon generating sufficient taxable
income to utilize such assets. Although realization is not assured, management
believes it is more likely than not that the deferred tax assets for which a
valuation allowance has not been provided will be realized.

YEARS ENDED DECEMBER 31, 1995 AND 1996

          Corporate Revenues.  For the year ended December 31, 1996, total
          -------------------                                             
revenue decreased $15.3 million from $113.4 to $98.1 million. This decrease was
the result of a decrease in product sales.

          Product Sales.  For the year ended December 31, 1996, product sales
          --------------                                                     
decreased $15.3 million from $113.4 to $98.1 million. This decrease is the
result of the divestiture of certain products during the year, a decline in the
sale of certain products due in part to a shift in promotional activity and a
change in the timing of special discounts and special

                                      -28-

offers to the trade, increased generic competition and certain back order
situations, offset by fourth quarter sales of PROAMATINE.

          For the year ended December 31, 1996, sales of the Company's United
Kingdom subsidiary, Monmouth Pharmaceuticals, Ltd., decreased slightly from
$12.1 million to $12.0 million. Sales of the Company's Canadian subsidiary,
Roberts Pharmaceutical Canada, Inc., increased $0.6 million from $11.1 million
to $11.7 million. This increase is primarily the result of an increase in the
demand for products acquired during 1995 along with the launch of Advantage 24,
a contraceptive product.

          Cost of Sales.  For the year ended December 31, 1996, cost of sales
          --------------                                                     
amounted to 51% of product sales as compared to 47% in 1995. This increase in
cost of sales percentage and corresponding decrease in gross profit percentage
is primarily the result of an increase in inventory obsolescence resulting from
the decrease in demand for certain products for which inventory production
schedules had been previously agreed with third party suppliers. Cost of sales
continues to be impacted by sales of NOROXIN, a lower gross profit margin
product, in the Company's product mix.

          Research and Development.  Research and development expenses increased
          -------------------------                                             
from $6.1 million in 1995 to $7.4 million in 1996, an increase of 21.3%. (See
"Notes to Consolidated Financial Statements - Note 1"). This increase results
from expenditures in the development of the Company's two recently approved
products, AGRYLIN and PROAMATINE and purchases of certain development products.

          Marketing and Administrative Expenses.  Marketing and administrative
          --------------------------------------                              
expenses increased $9.6 million from $47.6 million in 1995 to $57.2 million in
1996. Marketing expenses increased $8.6 million primarily as a result of
increased promotional activities for some of the Company's new products
including PROAMATINE which was launched during the fourth quarter of 1996 and
increased compensation for the sales forces in the United States, United
Kingdom, and Canada. Administrative expenses increased $1.0 million during 1996
as compared to 1995 in large part due to expenses related to the shareholders'
lawsuit and increased insurance costs.

          Interest Income and Expense.  For the year ended December 31, 1996,
          ----------------------------                                       
interest income increased $.9 million to $2.9 million as the result of an
increased cash balance due to the private placements that were completed during
1996. Interest expense decreased from $3.5 million in 1995 to $1.8 million in
1996 as a result of a decrease in long-term debt related to product
acquisitions.

                                      -29-

          Income Taxes.  For the year ended December 31, 1996, income taxes from
          -------------                                                         
continuing operations decreased $17.4 million from a provision of $2.8 million
to a benefit of $14.6 million, primarily as a result of a decline in net income
including the write off and disposition of certain intangible assets. The
Company's effective tax benefit of 30% was lower than the normal statutory rate
primarily as a result of the Company's inability to recognize the benefit of the
Canadian net operating loss carryforwards.

          Intangible Dispositions and Write-Offs.  During the fourth quarter of
          ---------------------------------------                              
1996, the Company completed the sale of the majority of its nonprescription
products along with the NUCOFED and QUIBRON brands in two independent
transactions. These sales, net of proceeds, resulted in a one time, non-cash
write off of $11.9 million, which amounted to $7.6 million net of taxes. Also,
during the fourth quarter of 1996, the Company expensed certain purchased
development products and recorded an impairment loss of long-lived intangible
assets totalling $25.4 million, which amounted to $17.8 million net of taxes. If
the estimate of undiscounted cash flows to be generated by the remaining
intangible assets decreases in the future, an additional write-down of those
assets may be required.

     LIQUIDITY AND CAPITAL RESOURCES
     -------------------------------

          For the year ended December 31, 1997, operating cash inflows amounted
to $3.6 million as a result of the Company's net income enhanced by reductions
in accounts receivable and non-cash charges, primarily depreciation and
amortization, and offset by changes in accounts payable, other current
liabilities and inventory. As of December 31, 1997, the Company had cash, cash
equivalents and marketable securities of $82.8 million. These balances are
primarily attributable to the Common Stock Private Placement completed in July
1996 which resulted in net proceeds of approximately $9.9 million and the
Preferred Stock Private Placement completed in August 1996 which provided
approximately $98.8 million in net proceeds. For the year ended December 31,
1996, operating cash inflows amounted to $0.2 million as a result of the
Company's net loss offset by non-cash charges, including intangible asset
dispositions and write-offs. Cash inflows from operations amounted to $22.8
million in 1995.

          The Company's funding requirements will depend on a number of factors,
including the Company's product development programs, product acquisitions, the
level of resources required for the expansion of marketing capabilities,
especially relating to the Company's two approved pipeline products, PROAMATINE
and AGRYLIN, increased investment in accounts receivable and inventory which may
arise from increased sales levels, competitive and technological developments,
the timing and cost of obtaining required regulatory approvals for new products,
relationships

                                      -30-
<PAGE>
 
with parties to collaborative agreements, the success of acquisition activities
and the continuing revenues generated from sales of PROAMATINE and AGRYLIN.

          Existing cash and securities balances and cash generated from
operations are expected to be sufficient to fund operating activities for the
foreseeable future, as well as support near and long term debt obligations,
capital improvements for the manufacturing facility and development of the
existing pipeline compounds. Cash equivalents and marketable securities
currently consist of immediately available money market fund balances and
investment grade securities.

          Capital Expenditures.  Capital Expenditures in 1997 of approximately
          ---------------------                                               
$12 million relate primarily to the purchase of the pharmaceutical manufacturing
facility in Canada and the purchase of the distribution facility in the United
States. The Company anticipates additional capital expenditures in 1998 of
approximately $10 million for the purchase of certain manufacturing and computer
equipment associated with manufacturing, distribution and marketing activities.

          Foreign Currency Fluctuations.  The Company has subsidiary operations
          ------------------------------                                       
outside the United States. As a result, the Company is subject to fluctuations
in subsidiary revenues and costs reported in United States dollars as a
consequence of currency exchange rate fluctuations, especially rates for the
British pound and Canadian dollar. Such fluctuations were not material in 1997,
1996 and 1995.

          Concentration of Credit Risk.  Financial instruments that potentially
          -----------------------------                                        
expose the Company to concentrations of credit risk consist primarily of short
term cash investments and trade accounts receivable. The Company places its
temporary excess cash investments in short term money market instruments. At
times, such investments may be in excess of the FDIC insurance limit. The
Company markets its products primarily to wholesale drug distributors, retail
pharmacies and physicians in the United Stated and abroad. The Company performs
certain credit evaluation procedures and does not require collateral. Reserves
are maintained for estimated credit losses.

          Inflation.  Although at reduced levels in recent years, inflation
          ----------                                                       
continues to apply upward pressure on the cost of goods and services used by the
Company. However, the Company believes that the net effect of inflation on its
operations has been minimal during the past three years.

New Accounting Pronouncements
- -----------------------------

          Statement of Financial Accounting Standards No. 130, "Reporting
Comprehensive Income" (SFAS No. 130), establishes standards for reporting and
display of comprehensive income and its components (revenues, expenses, gains,
and losses) in a full set of general-purpose financial statements. This
Statement requires that all items that are required to be recognized under
accounting standards as components of comprehensive income be reported in a
financial statement that is displayed with the same prominence as other
financial statements. This Statement requires that a company (a) classify items
of other comprehensive income by their nature in a financial statement and (b)
display the accumulated balance of other comprehensive income separately from
retained earnings and additional paid-in capital in the equity section of a
statement of financial position. This Statement is effective for fiscal years
beginning after December 15, 1997. Reclassification of financial statements for
earlier periods provided for comparative purposes is required.

          Statement of Financial Accounting Standards No. 131, "Disclosures
about Segments of an Enterprise Related Information" (SFAS No. 131), establishes
standards for the way that public business companies report information about
operating segments in annual financial statements and requires that those
companies report selected information about operating segments in annual
financial statements and requires that those companies report selected
information about operating segments in interim financial reports issued to
stockholders. It also establishes standards for related disclosures about
products and services, geographic areas, and major customers. This Statement
supersedes SFAS No. 14, "Financial Reporting for Segments of a Business
Enterprise," but retains the requirement to report information about major
customers. This Statement is effective for financial statements for periods
beginning after December 15, 1997. In the initial year of application,
comparative information for earlier years is to be restated.

          The adoption of these Statements will not have an impact on the
Company's consolidated results of operation, financial position or cash
flow.

YEAR 2000 CONVERSION
- --------------------

          The Company has evaluated the impact of changes necessary to achieve a
year 2000 date conversion. Software failures due to processing errors arising
from calculations using the year 2000 date are a known risk. Major areas of
potential impact have been identified and it is management's opinion that the
software currently in use, or that which will be in use at the time, is year
2000 compliant. Therefore, the Company does not expect a material impact on
future results due to conversion.

                       ---------------------------------



To the Board of Directors and Shareholders 
Roberts Pharmaceutical Corporation:


We have audited the accompanying consolidated balance sheets of Roberts
Pharmaceutical Corporation and Subsidiaries as of December 31, 1997, 1996 and
1995, and the related consolidated statements of operations, cash flows, changes
in shareholders' equity for each of the three years in the period ended December
31, 1997 and the financial statement schedules on pages F-25 to F-27 of this
Form 10-K.  These financial statements and financial statement schedules are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these financial statements and financial statement schedules 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 Roberts
Pharmaceutical Corporation and Subsidiaries as of December 31, 1997, 1996 and
1995, and the consolidated results of their operations and their cash flows for
each of the three years in the period ended December 31, 1997 in conformity with
generally accepted accounting principles. In addition, in our opinion, the
financial statement schedules referred to above, when considered in relation to
the basic financial statements taken as a whole, present fairly, in all material
respects, the information required to be included therein.



                                                        COOPERS & LYBRAND L.L.P.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.        SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
          ------------------------------------------

          Basis of Presentation
          ---------------------

               Roberts Pharmaceutical Corporation is an international
          pharmaceutical company which licenses, acquires, develops and
          commercializes post-discovery drugs in selected therapeutic
          categories.  The Company currently markets approved pharmaceutical
          products in the United States, Canada, the United Kingdom and several
          other European countries.  The consolidated financial statements
          include the accounts of Roberts Pharmaceutical Corporation and its
          majority-owned subsidiaries.  All significant intercompany
          transactions are eliminated.  All dollar amounts are presented in
          thousands, except for earnings per share.

          Revenue Recognition
          -------------------

               Product sales, net of estimated future returns, are recorded as
          the products are shipped against customer orders.

               Licensing revenues are recorded as earned under the terms of each
          underlying agreement and are included in other revenue.

          Cash Equivalents and Marketable Securities
          ------------------------------------------

               Cash equivalents include all money market investments with
          original maturities of three months or less.

               Marketable securities consist primarily of debt instruments with
          maturities of more than three months and are stated at amortized cost
          plus accrued interest, which approximates fair value.

          Inventories
          -----------

               Inventories, consisting primarily of finished goods, are stated
          at the lower of first-in, first-out cost or market.

          Use of 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

                                      F-7

                      ROBERTS PHARMACEUTICAL CORPORATION
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

     contingent assets and liabilities at the date of the financial statements
     and revenues and expenses during the period reported. Actual results could
     differ from those estimates.  Estimates include accounting for allowance
     for doubtful accounts, inventory obsolescence, future product returns,
     depreciation and amortization, value of intangibles, employee benefit
     plans, taxes, discontinued operations and contingencies.

               Fixed Assets and Depreciation
               -----------------------------

               Fixed assets are stated at cost less accumulated depreciation.
     Depreciation is determined using the straight-line method over the
     estimated useful lives of the related assets ranging from five to fifty
     years.  Gains and losses on disposals are recognized in the year of the
     disposal.  Expenditures for maintenance and repairs are expensed as
     incurred; significant renewals and betterments are capitalized.

               Intangible Assets
               -----------------

               Intangible assets are stated at cost less accumulated
     amortization.  Amortization is determined using the straight-line method
     over the estimated useful lives of the related assets which are estimated
     to range from ten to forty years.  It is the Company's policy to review
     periodically and evaluate whether there has been an impairment in the value
     of intangibles.

          In the fourth quarter of 1996, the Company recorded a charge to
     earnings for an impairment of intangible assets and to expense certain
     purchased development products totalling $25.4 million.

     Foreign Currency Translation
     ----------------------------

          Effective January 1, 1997, the functional currency of the United
     Kingdom subsidiary, Monmouth Pharmaceutical, Ltd., was changed from the
     U.S. dollar to the British pound as a result of a change in circumstance.
     Monmouth's translation gains and losses for 1997 are accumulated as a
     separate component of Shareholders' Equity.  In 1996 and 1995, Monmouth's
     accounts were remeasured in dollars and translation gains and losses were
     included in income in those years.

          The functional currency of the Company's Canadian subsidiary is the
     Canadian dollar.  Translation gains and losses of the Company's Canadian
     subsidiary are accumulated as a separate component of Shareholders' Equity.

               Included in the balance sheet at December 31, 1995, 1996 and 1997
     is debt of $1,849, $832 and $0, respectively, denominated in British
     pounds.

     Concentration of Credit Risk
     ----------------------------

               The Company markets prescription and nonprescription
     pharmaceuticals primarily to wholesale drug distributors, retail pharmacies
     and physicians in the United States and abroad.  The Company performs
     certain credit evaluation procedures and does not require collateral.  The
     Company maintains reserves for estimated credit losses; at  December 31,
     1995, 1996 and 1997, the reserve for uncollectible accounts amounted to
     $1,754, $1,440 and $440, respectively.

               At December 31, 1997, cash equivalents and marketable securities
     consisted of immediately available money market fund balances and
     investment grade debt and preferred stock securities with maturities of
     less than one year.

               The fair value of investment securities classified as available
     for sale, totaled $40,086 at December 31, 1997.  These investment
     securities mature within one year.

     Earnings (loss) per share
     -------------------------

               As of December 15, 1997, the Company has adopted the provisions
     of SFAS 128.  Basic income (loss) per share was computed based on the
     weighted average number of shares of Common Stock actually outstanding.
     Diluted earnings per share were calculated based on the Common Shares
     outstanding plus the dilutive effect of potentially dilutive common stock.

          The effect of conversion of the original shares of Preferred Stock for
December 31, 1996 is not included in the calculation of earnings per share
because inclusion would be antidilutive.  The remaining original 5% Preferred
Stock shares were convertible into 1,332,322 shares of Common Stock at December
31, 1997.  Other common stock equivalents which could result in dilution of
earnings in future periods, depending on the market price of the Company's
Common Stock, are stock options held by employees and Common Stock Warrants
granted to the Placement Agent of the 5% Preferred Stock.  See Note 8.,
Shareholders' Equity, for further discussion of these securities.

          Pursuant to a position taken by the SEC staff (the "Staff"), effective
March 13, 1997, on accounting for preferred stock which is convertible at a
discount to market, the Company adjusted its calculation of 1996 Earnings Per
Share by $.61 per share.  This reflected the Staff's position that the 10%
discount available to holders of the Company's 5% Preferred Stock should be
incorporated in the calculation of Earnings Per Share.

New Accounting Pronouncements
- -----------------------------

          Statement of Financial Accounting Standards No. 130, "Reporting
Comprehensive Income" (SFAS No. 130), establishes standards for reporting and
display of comprehensive income and its components (revenues, expenses, gains,
and losses) in a full set of general-purpose financial statements. This
Statement requires that all items that are required to be recognized under
accounting standards as components of comprehensive income be reported in a
financial statement that is displayed with the same prominence as other
financial statements.  This Statement requires that a company (a) classify items
of other comprehensive income by their nature in a financial statement and (b)
display the accumulated balance of other comprehensive income separately from
retained earnings and additional paid-in capital in the equity section of a
statement of financial position. This Statement is effective for fiscal years
beginning after December 15, 1997.  Reclassification of financial statements for
earlier periods provided for comparative purposes is required.

          Statement of Financial Accounting Standards No. 131, "Disclosures
about Segments of an Enterprise Related Information" (SFAS No. 131), establishes
standards for the way that public business companies report information about
operating segments in annual financial statements and requires that those
companies report selected information about operating segments in annual
financial statements and requires that those companies report selected
information about operating segments in interim financial reports issued to
stockholders.  It also establishes standards for related disclosures about
products and services, geographic areas, and major customers.  This Statement
supersedes SFAS No. 14, "Financial Reporting for Segments of a Business
Enterprise," but retains the requirement to report information about major
customers.

beginning after December 15, 1997.  In the initial year of application,
comparative information for earlier years is to be restated.

          The adoption of these Statements will not have an impact on the

     Intangible Dispositions and Write-Offs.
     ---------------------------------------

               During the fourth quarter of 1996, the Company completed the sale
     of the majority of its non-core nonprescription brands along with the
     NUCOFED and QUIBRON brands in two independent sales agreements.  These
     sales, net of proceeds, resulted in a one time, non-cash write off of $11.9
     million, which amounted to $7.6 million net of taxes.  Also, during the
     fourth quarter of 1996, the Company expensed certain purchased development
     products and recorded an impairment loss of long-lived intangible assets
     totalling $25.4 million, ($17.8 million net of taxes).  If the estimate of
     undiscounted cash flows to be generated by the remaining intangible assets
     decreases in the future, an additional write-down of those assets may be
     required.

               Operating income and net loss for 1996 were negatively affected
     by the purchase of development products, the sale and write down of the
     intangible assets in the amounts of $37.3 million for operating income and
     $25.4 million for net loss.  The operating loss would have amounted to
     $12.9 million and net loss would have been $8.3 million if such
     transactions had not occurred.

Principles Board Opinion No. 25 and related interpretations in accounting for
its plans.  If the Company had elected to recognize compensation cost based on
the fair value at the grant dates for awards in 1995, 1996 and 1997, consistent

would have been changed to the pro forma amounts indicated below:

     the Black-Scholes option-pricing model with the following weighted average
     assumptions:  dividend yield of 0%; expected volatility of 54%; a risk free
     interest rate of 6%; and a general expectation that employees will exercise
     options when they become vested.

       The weighted average fair value of stock options, calculated using the
     Black-Scholes option-pricing model, granted during the years ended December
     31, 1996 and 1997 was $7.17 and $8.48, respectively.

       On July 17, 1996, the Company issued and sold in a private placement to
     certain investment funds 600,000 shares of the Company's Common Stock at an
     issue price of $16.65 per share resulting in gross proceeds to the Company
     of $9.9 million.  In addition to receiving cash consideration equal to 5%
     of the gross proceeds and the reimbursement of certain expenses, the
     Placement Agent received Common Stock Warrants to acquire an aggregate of
     15,000 shares of Common Stock for a purchase price of $16.65 per share.
     These warrants expire in July of 1999.

       On August 29, 1996, the Company issued and sold in a private placement to
     approximately eighty accredited investors for $25 per share an aggregate of
     4,200,000 shares of cumulative 5% Preferred Stock resulting in gross
     proceeds of $105 million.  In addition to receiving cash consideration
     equal to 5% of the gross proceeds and the reimbursement of certain expenses
     the Placement Agent received Preferred Stock Warrants to acquire 420,000
     shares of 5% Preferred Stock for a purchase price of $25 per share. These
     warrants expire in August 1998.  In 1997, 240,225 of these warrants were
     exercised, resulting in gross proceeds of $6 million.  The 5% Preferred
     Stock is convertible into a number of shares of Common Stock which depends,
     in part, upon the conversion price in effect at the time of the conversion.
     The 5% Preferred Stock is convertible into Common Stock at a 10% discount
     to market.  Of the total 4,440,225 5% Preferred Stock shares issued,
     3,964,571 shares have been converted into shares of Common Stock, of which
     2,485,601 shares were converted in 1997.  On August 29, 1998, all remaining
     outstanding shares of the 5% Preferred Stock will be automatically
     converted into Common Stock at the conversion price then in effect.

     Stock Compensation Plans
     ------------------------

       In prior years, executives and key employees of the Company were granted
     stock option awards under the Incentive Stock Option Plan.  In May of 1996,
     the Company's shareholders approved the Equity Incentive Plan which became
     effective May 22, 1996.  The Company's Incentive Stock Option

     Plan was discontinued on the same date.  The Equity Incentive Plan provides
     for the grant of incentive and nonqualified stock options, stock
     appreciation rights, deferred stock awards, restricted stock grants and
     other stock based awards to executives and key employees.  The total number
     of shares of Common Stock authorized for grant under the Equity Incentive
     Plan is 1,500,000.

               Options to purchase Common Stock may be granted either alone or
     in addition to other awards.  The term of each option will be fixed by the
     Compensation Committee (the "Committee") of the Company's Board of
     Directors, provided that no incentive stock option, as defined in the
     Internal Revenue Code, will be exercisable after the expiration of ten
     years from the date the option is granted.  Options will be exercisable at
     such time or times as determined by the Committee at or subsequent to
     grant. Stock Appreciation Rights ("SARS") may be granted to participants
     either alone or in addition to stock options and may, but need not be,
     related to a specific option.  The provisions of SARs need not be the same
     with respect to each recipient.

               Performance awards, restricted stock awards and other stock unit
     awards may also be granted.  Presented below is the total number of the

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

               A valuation allowance was provided for certain foreign net
     operating losses and certain state deferred tax assets due to the
     uncertainty of realization of these assets.

               The Company has recorded net deferred tax assets of approximately
     $17.3 million.  Realization is dependent upon generating sufficient taxable
     income to utilize such items. Although realization is not assured,
     management believes it is more likely than not that the deferred tax assets
     for which a valuation allowance has not been provided, will be realized.
     The amount of the deferred tax assets considered realizable, however, could
     be reduced at any time if estimates of future taxable income are reduced.

     9.  LEASES AND OTHER COMMITMENTS
         ----------------------------

               The Company leases office space and certain office equipment
     under operating leases.  Minimum rental payments in each of the next five

     NOROXIN, SAMPATRILAT and the Lilly Compounds totalling $46.3 million and
     purchase PROAMATINE inventory in the amount of $50.1 million through 2002.

     10.EMPLOYEE BENEFITS

               Through December 31, 1997 the Company maintained an employee
     savings plan available to all employees who met certain age and service

     employee compensation or employee contributions. In the years ended
     December 31, 1995, 1996 and 1997, the Company contributions amounted to
     $231, $197, and $258 respectively.

               Also through December 31, 1997, the Company had a money purchase
     pension plan available to all employees who met certain age and service
     requirements.  The Company made discretionary contributions to the plan

     contributions amounting to $217, $206, and $248 respectively.

               As of January 1, 1998, the two plans were merged into one

     certain age and service requirements.  The plan requires mandatory
     contributions to the plan based on employee contributions and makes
     discretionary contributions to the plan based on employee compensation.

     Employee Stock Purchase Plan
     ----------------------------

               The Company's Board of Directors approved the Employee Stock
     Purchase Plan (the "Plan"), which gives employees of the Company the
     opportunity to purchase shares of the Company's Common Stock through
     payroll deductions beginning on April 1, 1997.  Employees can elect to
     participate in the Plan by designating from 1% to 10% of eligible
     compensation to be deducted from pay.  On the date of exercise, which is
     the Friday before the 15th of the month following each quarter end, the per
     share purchase price will be 85% of the average high and low per-share
     trading price of Roberts common stock on the American Stock Exchange on
     that date.  500,000 shares of the Company's Common Stock have been reserved
     for issuance under the Employee Stock Purchase Plan. The total number of
     shares purchased under the plan in the year ended December 31, 1997 was
     4,045 with a total value of $39,388.

     11.CONTINGENCY
        -----------

               A shareholder class action suit was instituted in March, 1995, in
     the United States District Court for the District of New Jersey against the
     Company and certain of its officers and a former officer for alleged
     violations of certain federal securities laws.  This suit has been settled.
     The net expenses of this settlement to the Company amounted to $2.3 million
     and were included in other expense for the quarter ended September 30,
     1997.

     14.DISCONTINUED OPERATIONS
        -----------------------

               In August 1995, the Company decided to seek a buyer for the
     assets of its Pronetics (Homecare) subsidiaries which were located in New
     York, New Jersey, North Carolina, and South Carolina.

               The sale of the Homecare division was expected to result in a
     loss at closing.  Accordingly, the Company charged 1995 operations with the
     estimated loss on discontinuing Homecare of $9.7 million, including a
     provision of $1.9 million for operating losses until disposal of which $1.3
     million was used in the third and fourth quarters of 1995.

               Sales of the Homecare subsidiaries were essentially completed in
     December 1996.  The total realized from the sales was $2.7 million.  The
     additional loss on sale was offset by a decrease in the assets held for
     sale and lower than expected losses from operations in 1996.  There was no
     income statement effect from the final disposition of the Homecare
     division.  An additional loss of $2.5 million on disposal of the Hauck
     division was recognized in 1996.  This expense was due to impairment of the
     division's product intangibles.

               In March 1996, the Company announced its plan to discontinue and
     divest VRG, a contract clinical research organization.  The Company
     expected the sale of VRG to result in a loss at closing. Accordingly, the
     Company charged 1995 operations with the estimated loss on discontinuing
     VRG of $12.8 million, including a provision of $5.0 million for operating
     losses until disposal. At December 31, 1995, net assets expected to be
     realized, consisting primarily of receivables and plant and equipment,
     totaled $0.5 million.  In 1996, the Company reassessed the estimated
     operating loss which resulted in an income statement impact of a $3.1
     million gain.  In January, 1998, the Company signed a Letter of Intent to
     sell VRG's operations subject to the execution of a definitive acquisition
     agreement and the successful completion of due diligence by the purchaser.
     To date, the Company and the purchaser are negotiating the terms of said
     definitive acquisition agreement and the transaction is expected to close
     within the month of April, 1998.

     15.FAIR VALUE OF FINANCIAL INSTRUMENTS
        -----------------------------------

     The carrying amount of cash and cash equivalents approximates fair value
     due to the short-term maturities of these instruments. The fair value of
     marketable securities was estimated based on quotes obtained from brokers.
     The fair value of long-term debt is estimated based on the discounted
     future cash flows using currently available interest rates.

     (1)  Subsequent to the filing of the Company's quarterly report on Form 10-
          Q for the three months ended March 31, 1997, the Company reclassified
          costs that had been capitalized as an intangible asset to research and
          development expense.  The net of tax charge to earnings was $660,000,
          or $0.02 per share.

     (2)  Includes a $2.3 million charge for the settlement of a lawsuit
          instituted against the Company for alleged violations of certain
          federal securities laws.

     (3)  In fourth quarter 1997, management made several changes in the
          estimates of income tax reserves and allowances for returned goods.
          The reduction in income tax reserves resulted from the elimination of
          certain reserves due to the closure of years 1991 through 1993 after
          an IRS audit.  The allowance for returned goods was revalued based
          upon a change in estimate of the economic benefit from the product
          returns.  The impact of these revaluations was $2.7 million and $1.0
          million respectively.

     (4)  Includes a $4.0 million credit for the reassessment of the reserve for
          discontinued operations, established in 1995.

     (5)  Includes a $25.4 million charge for the purchase of certain
          development products and the write-off and sale of certain intangible
          assets.  (See Note 4.)

     (6)  Includes $.21 and $.40 per share charge for the third and fourth
          quarter, respectively, pursuant to the 10% discount to market upon
          conversion of the 5% Preferred Stock into Common Stock.  Such amount
          was not included in the Company's third quarter 1996 10-Q.  The amount
          is included based on the SEC position effective March 13, 1997 on such
          discounts.  In addition, includes $.02 and $.04 per share charge for
          the third and fourth quarter, respectively, pursuant to dividends paid
          and accrued on 5% Preferred Stock.

     billing and shipping errors are no longer included in the estimation as
     these items are restocked and salable.

                                                              -------------- 
                Escrow Agent shall promptly send a copy thereof to the other
                party.  The other party shall have the right to object to the

                three (3) business days after Escrow Agent delivers a copy of
                the written demand to the objecting party but not thereafter.
                Such notice shall set forth the basis for objecting to the

                instructions received and either (i) hold the Deposit until the
                dispute is mutually resolved and Escrow Agent is advised of this
                fact in writing by both Seller and Purchaser, or Escrow Agent is
                otherwise instructed by a final unappealable judgment of a court
                of competent jurisdiction, or (ii) deposit the Deposit with a
                court of competent jurisdiction (whereupon Escrow Agent shall be
                released and relieved of any and all liability

                deposit).

                (d) In the event Escrow Agent shall be uncertain as to its
                duties or rights hereunder or shall receive conflicting
                instructions, claims or demands from the parties hereto, or
                instructions which conflict with any of the provisions of this
                Agreement, Escrow Agent shall be entitled (but not obligated) to
                refrain from taking any action other than to keep safely the
                Deposit until Escrow Agent shall be instructed otherwise, in
                writing signed by both Seller and Purchaser, or by final
                judgment of a court of competent jurisdiction.

                (e) Escrow Agent may rely upon, and shall be protected in acting
                or refraining from acting upon, any written notice, instruction
                or request furnished to it hereunder and believed by it to be
                genuine and to have been signed or presented by the proper party
                or parties, provided that no modification of this Agreement
                which purports to affect the rights, duties or obligations of
                Escrow Agent hereunder shall be binding upon Escrow Agent unless
                Escrow Agent has signed such modification.

                (f) Seller and Purchaser shall jointly and severally hold Escrow
                Agent harmless against any loss, damage, liability or expense
                incurred by Escrow Agent not caused by its willful misconduct or
                gross negligence, arising out of or in connection with its
                entering into this Agreement and the carrying out of its duties
                hereunder, including the reasonable costs and expenses of
                defending itself against any claim of liability or participating
                in any legal proceeding.  Escrow Agent may consult with counsel
                of its choice, and shall have full and complete authorization
                and protection for any action taken or suffered by it

                duties or obligations hereunder by giving notice in writing of
                such resignation specifying a date when such resignation shall
                take effect; provided, however, that Escrow Agent, prior to such
                resignation, identifies a replacement escrow agent (the
                "Replacement Escrow Agent") who:  (i) is approved in writing by
                Seller and Purchaser, which approval shall not be unreasonably
                withheld or delayed; (ii) signs a counterpart of this Agreement;
                (iii) receives the Deposit from Escrow Agent and acknowledges
                receipt thereof; and (iv) agrees to be bound by all of the
                provisions hereof. If Escrow Agent resigns and no Replacement
                Escrow Agent is designated, Escrow Agent shall deposit the
                Deposit with a court of competent jurisdiction.  After
                resigning, as described above, Escrow Agent shall have no
                further duties or liability hereunder.

                (h) Purchaser and Seller, together, shall have the right to
                terminate the appointment of Escrow Agent hereunder by giving to
                it notice of such termination, specifying the date upon which
                such termination shall take effect and designating a Replacement
                Escrow Agent, consistent with clauses (i) through (iv) of
                Section 1.4(g) above.  After such termination, Escrow Agent

                shall have no further duties or liability hereunder.

                (i) Seller and Purchaser shall share equally the responsibility
                for reimbursement to Escrow Agent or Replacement Escrow Agent of
                all out-of-pocket expenses, disbursements and advances incurred
                or made by either in connection with the carrying out of its
                duties hereunder.

terminating this Agreement, provided that (i) Seller, promptly after discovering
the condition, assures Purchaser in writing that Seller is capable of curing
such condition prior to the closing, and (ii) Seller acts diligently to cure the
condition and completes such cure prior to the closing. Seller agrees that it
shall not intentionally take any action or intentionally omit to take any

against the other hereunder.  In the event Purchaser does not terminate this
Agreement by reason of any such taking, then and in that event, the sale of the

breach of any

representation or warranty by Purchaser expressly set forth in this Agreement.

          10.2  Default by Seller.  Purchaser may terminate this Agreement by
                -----------------                                            
notice to Seller at any time prior to the Closing Date in the event of a
material default by Seller under this Agreement (which remains uncured for ten
(10) business days after Purchaser's notice to Seller thereof) or a material
breach of any representation or warranty by Seller expressly set forth in this
Agreement.

          10.3  Remedies.  (a) If Seller fulfills its obligations hereunder but
                --------                                                       
Purchaser materially defaults under this Agreement, or materially breaches any

exclusive remedy hereunder, have the right to terminate this Agreement and
receive the Deposit together with all interest earned thereon and upon payment
thereof this Agreement shall terminate and the parties hereto shall be relieved
of any further liability or obligation to each other, it being expressly
understood that the payment of such sum to Seller as aforesaid shall be the sole
and exclusive right and remedy of Seller, and constitutes a fair and reasonable
estimate of the amount of damages to be sustained by Seller by reason of
Purchaser's breach of this Agreement.

materially defaults under this Agreement, or materially breaches any
representation or warranty contained herein, Purchaser may elect, as the sole

Purchaser may incur as a result of such willful breach.  Following such
election, Seller shall be relieved of any and all further liability and under no
circumstances shall Seller be liable to Purchaser for any damages whether such
damages are direct or consequential.

                -------------------------------------                         
they have dealt with each other and not through any real estate broker,
investment banker, person, firm or entity who would by reason of such dealings
be able to claim a real estate brokerage, business opportunity brokerage or
finder's fee as the procuring cause of this transaction.  Each of the parties
agrees to indemnify the other and hold the other harmless of and from any and
all loss, cost, damage, injury or expense arising out of, or in any way related
to, assertions by any other person, firm or entity of a claim to real estate
brokerage, business opportunity brokerage or finder's fee based on alleged
contacts between a party claiming to be a broker and an indemnifying party which
have resulted in allegedly providing the party claiming to be a broker the right
to claim such commission or finder's fee. The provisions of this Section 11.2
                                                                 ------------

Agreement without the prior consent of Seller, provided, however, that Purchaser
shall have the right to assign its rights under this Agreement to an entity
controlling, controlled by or under common control with Purchaser ("Affiliate")
without the consent of Seller.  In the event of an assignment to an Affiliate,
Purchaser shall notify Seller and the named Purchaser herein shall remain fully
liable for the obligations of the Purchaser hereunder.  For purposes hereof, the
term "control" means the power to direct and influence the management of an
entity.

          11.4  Notices.   All notices or other communications required or

            claims, suits, actions or other proceedings which are pending or

            ----------

       (j)  Financial Results.  The pro forma financial information in Schedule
            -----------------                                                  
            4.1(j) is correct and fairly presents in all material respects the
            results of operations of the Business for the periods identified.

            -----------------------

            -------------

       (c)  Consents of Third Parties.  The execution, delivery and performance
            -------------------------

            organizational documents and will not conflict with or result in the
            breach or termination of or constitute a default under any
            agreement, commitment or other instrument, or any order, judgment or
            decree, to which it is a party or by which it is bound; or (ii)
            constitute a violation by it of any law or regulation applicable to
            it.  No consent, approval or authorization of, or declaration or
            filing (other than the filings with the FDA to assign Product
            Rights) with, any governmental authority or any third party is

       (b)  use reasonable efforts, consistent with past practice, to preserve
            the goodwill of Roberts' customers, suppliers and others having
            business relations with it with respect to the Business.

5.2    Notice of Events.  From the date hereof and until the Closing Date,
       ----------------                                                   
       Roberts shall promptly advise Searle in writing of, and furnish any
       information Searle may reasonably request with respect to, (a) any claim,
       litigation, proceeding or 
<PAGE>
 
                                      -11-

       governmental investigation of which it has knowledge that is threatened
       or asserted by or against Roberts and directly involves the Business and
       (b) any event or condition of which it has Knowledge that would cause any
       of the conditions to Searle's obligation to consummate the purchase and
       sale under this Agreement not to be fulfilled. Searle shall promptly
       advise Roberts in writing of, and furnish any information Roberts may
       reasonably request with respect to, any event or condition of which
       Searle has Knowledge that would cause any of the conditions to Roberts'
       obligation to consummate the purchase and sale under this Agreement not
       to be fulfilled.

5.3    Access to Information.  Prior to the closing, Roberts shall permit Searle
       ---------------------                                                    
       and its representatives to make such investigation of the Product Rights
       and Business as Searle may reasonably request and give Searle and its
       counsel, accountants and other representatives full access, upon
       reasonable notice, during normal business hours throughout the period
       prior to the Closing Date, to information concerning such Product Rights
       and the records and files of the Business.  Any investigation by Searle
       shall be conducted in such manner as to minimize interruption of Roberts'
       business.  If for any reason the purchase and sale under this Agreement
       is not consummated, Searle shall return any documents delivered to it by
       Roberts.

5.4    Confidentiality of Information Prior to Closing.  Except as otherwise
       -----------------------------------------------                      
       required by law, Searle shall keep confidential any information obtained
       by it and its representatives in connection with the transactions
       contemplated by this Agreement, pursuant to the confidentiality agreement
       referenced in Section 9.7.

5.5    Consents; Assignment of Agreements.  Roberts shall use reasonable efforts
       ----------------------------------                                       
       (but shall not be required to make any payment) to obtain at the earliest
       practicable date but in no event later than the Closing Date, by
       instruments in form and substance reasonably satisfactory to Searle, all
       consents and approvals to the assignment of material agreements and
       commitments as listed in Schedule 4.1(h).  If, with respect to any
       commitment or agreement to be assigned to Searle or Transferee (whether
       or not listed on Schedule 4.1(h)), a required consent to the assignment
       is not obtained (and, accordingly, pursuant to Section 1.14, it is
       excluded from the sale to Searle), Roberts shall use reasonable efforts
       to keep in effect and give Searle or Transferee (at Searle's 
<PAGE>
 
                                      -12-

       or Transferee's cost and expense) the benefit of such commitment or
       agreement to the same extent as if it had been assigned and to the extent
       not prohibited by that commitment or agreement, and Searle or Transferee
       shall perform Roberts' obligations under the commitment or agreement or
       cooperate in Roberts' performance of such obligations. Nothing in this
       Agreement shall be construed as an attempt to assign any commitment or
       agreement that is by its terms nonassignable without the consent of the
       other party.

5.6    Other Action.  Each of the parties to this Agreement shall use all
       ------------                                                      
       reasonable efforts to cause the fulfillment at the earliest possible date
       of all the conditions to the obligations of the other party to consummate
       the purchase and sale under this Agreement.

5.7    Further Assurances.  At any time and from time to time after the Closing
       ------------------                                                      
       Date, each of the parties shall, without further consideration, execute
       and deliver such additional instruments of transfer and assumption, and
       shall take such other action, as the other party may reasonably request
       to carry out the transactions contemplated by this Agreement and effect
       an orderly transition of the Business.

5.8    License.  From and after the Closing Date, but limited to use in the
       -------                                                             
       Territory with respect to the Product, Roberts hereby grants Searle and
       Transferee the non-exclusive, perpetual, royalty-free right (which may be
       sub-licensed by Searle or Transferee to third parties for use on behalf
       of Searle or Transferee) to practice and use the Other Rights.

5.9    NDC Numbers.  Promptly following the Closing Date, Searle or Transferee
       -----------                                                            
       shall take any and all action necessary to change the National Drug Code
       number for the Product.

5.10   Labels and Package Inserts.  Subject to compliance with applicable laws
       --------------------------                                             
       and regulations, (i) Roberts agrees to permit Searle and Transferee to
       continue to use the labeling and packages, and package inserts that are
       existing in Roberts' finished goods inventory on the Closing Date and
       (ii) Roberts agrees to permit Searle and Transferee to use, without
       modification, the Product literature currently in stock, if any, for
       distribution and sales efforts.  In no event shall Searle or Transferee
       use such existing materials or any other Product labeling, packages or
       package inserts (including any 
<PAGE>
 
                                      -13-

       referencing Roberts name) for a period longer than one hundred eighty
       (180) days from the Closing Date (the "Initial Period"), plus an
       additional ninety (90) days after the expiration of the Initial Period
       for those materials described in sub-section (i) of this Section 5.10
       used in finished goods existing as of the end of the Initial Period.
       Notwithstanding the foregoing, Searle and Transferee shall use their best
       efforts to reduce each period of such uses to the minimum time possible.

5.11   Returns of Product
       ------------------

       (a)  Returns will be the financial responsibility of the party that
            originally sold the returned Product.   Returns shall be tracked by
            lot number.  Returned Product with lot numbers sold exclusively by
            Roberts will be the financial responsibility of Roberts; returned
            Product with lots numbers sold exclusively by Searle will be the
            responsibility of Searle; financial responsibility for returned
            Product from lots where each party sold a portion of the lot will be
            prorated based on the portion of the shared lot that each party
            sold.

       (b)  Both parties agree to enforce preauthorized return or scan and
            destroy procedures in an attempt to have customer return Product
            and obtain credit from the party who originally sold the Product to
            them.  Both parties agree to accept returns from the prorated lot.
            However, either party may accept Product returns for which they are
            not financially responsible in order to maintain their reputation
            and good will in the marketplace and the financially responsible
            party will reimburse the party processing the return.  In these
            cases, the processing party will verify the price the customer
            originally paid (and therefore the credit provided) with the party
            who originally sold the Product.

5.12   Chargebacks and Rebates
       -----------------------

       (a)  Roberts will be financially responsible for all chargeback claims
            related to Product sold by a wholesaler to a chargeback contract
            customer on and after the Closing Date and during the first three
            (3) months of 1998.

       (b)  Roberts will be financially responsible for all managed care rebates
            related to Product dispensed by a pharmacist on and after the
            Closing Date and during the first six (6) months of 1998.
<PAGE>
 
                                      -14-

       (c)  In general, Searle will forward to Roberts for payment any claims
            received related to Sections 5.12(a) and (b) above for which Roberts
            is financially responsible.  However, for the purpose of
            administrative convenience or at the specific request of a customer,
            Searle may elect to pay the claim for which Roberts is financially
            responsible and Roberts will reimburse Searle with respect to such
            claim.

       (d)  Roberts will be financially responsible for all Medicaid rebates
            related to Product dispensed by a pharmacist on and after the
            Closing Date and during the first six (6) months of 1998. HCFA will
            continue to bill Roberts for Medicaid rebates for up to one year
            after the expiration date on the last Norethin product issued with a
            Roberts labeler code. For administrative convenience, Roberts will
            continue to pay all future Medicaid rebates claims it receives.
            Searle will reimburse Roberts for any rebate claims paid by Roberts
            but which relate to Product dispensed by a pharmacist after the
            aforesaid first six months of 1998.

       (e)  Roberts shall continue to make any chargeback or rebate payments
            with respect to the Product required under agreements, government
            mandates or otherwise which relate to supply contracts not assigned
            or assignable under Section 5.5 or which are processed by Roberts
            due to direct requests of a customer, provided that Searle shall
            reimburse Roberts for all such payments pursuant to Section 5.12(d)
            above.

5.13   Assignment to Transferee.  Searle may elect to assign its
       ---------------------------                              
       responsibilities under Sections 5.11 and 5.12 to Transferee, upon which
       Transferee shall be directly responsible with respect thereto.
       Notwithstanding the foregoing, Searle shall remain liable for its
       obligations under Sections 5.11 and 5.12 in the event that Transferee
       fails to honor such obligations.

5.14   Post-Closing Services.  From the Closing Date and until the expiration of
       ---------------------                                                    
       twelve (12) weeks thereafter, Roberts shall perform the following
       services:

       (a)  notify all customers and government formularies of the transfer of
            the Product to Searle or Transferee (providing Searle or Transferee
            with a duplicate set of mailing labels for its use);
<PAGE>
 
                                      -15-

       (b)  print notifications of the sale of the Product on selected invoices;
            and

       (c)  invoice, book sales and ship Product as agent for Searle or
            Transferee and use all reasonable efforts (short of instituting
            third party collection or legal proceedings) to collect amounts due
            for Product so shipped.  For its services, Searle or Transferee
            shall pay Roberts a fee equal to [DELETION] such fee to be paid in
            monthly installments within ten (10) days of Roberts' invoice
            therefor.

       warranties of each of the parties contained in this Agreement shall

       warranties will expire on the first anniversary of the Closing Date.
       There are no representations or warranties other than those set forth in

       -------------------------                                            
       Article 7, Roberts shall indemnify and hold Searle, Transferee and their
       respective Affiliates harmless from and against any loss, liability,
       damage or expense (including, but not limited to, reasonable attorneys'
       fees) based upon, arising out of or otherwise resulting from any

       or agreement of Roberts contained in this Agreement or in any certificate
       or instrument of assignment delivered by it pursuant to this Agreement.

7.3    Indemnification of Roberts.  Subject to the limitations stated in this
       --------------------------                                            
       Article 7, Searle shall indemnify and hold Roberts and its Affiliates
       harmless from and against any loss, liability, damage or expense
       (including, but not limited to, reasonable attorneys' fees) based upon,
       arising out of or otherwise resulting from any inaccuracy in any
       representation or any breach of any warranty, covenant or agreement of
       Searle contained in this Agreement or in any certificate delivered by it
       pursuant to this Agreement.

7.4    Limitations on Recovery.  Neither Roberts nor Searle shall be liable to
       -----------------------                                                
       the other party under Sections 7.2 or 7.3 of this Article 7, as
       applicable, except to the extent that the aggregate amount of all claims
       for indemnity by the other party exceeds an amount equal to [DELETION].

7.5    Notice of Claims.  Indemnification pursuant to Sections 7.2 or 7.3 of
       ----------------                                                     
       this Article 7 shall apply only to the extent that notice of a claim
       therefor is asserted in writing and delivered to the indemnifying party
       prior to the end of the applicable time period set forth below:

       (a)  if the claim is based upon a third party claim for damages to
            property or personal injury resulting from the manufacture and/or
            use of the Product, whether based on breach of warranty, negligence,
            product liability or strict liability, the notice period shall be
            the statute of limitations for such claim;

       (b)  if the claim is based upon an assessment of taxes due, the notice
            period shall be the applicable statute of limitations; and

       (c)  for all other claims the notice period shall be one (1) year from
            the Closing Date.
<PAGE>
 
                                      -18-

       Any notice of such a claim shall state with reasonable specificity the
       representation, warranty, covenant or agreement with respect to which the
       claim is made, the facts giving rise to, and the alleged basis for, the
       claim, and, if known, the amount of liability asserted by reason of the
       claim.

7.6    Defense of Claims.  If any claim is made that would give rise to a right
       -----------------                                                       
       of indemnification under this Agreement, the party against whom the claim
       is made ("Claimant") shall afford the other party ("Indemnifying Party")
       and its counsel (reasonably satisfactory to Claimant), at the
       Indemnifying Party's expense, the opportunity to defend or settle the
       claim.  If such notice and opportunity are not given to the Indemnifying
       Party, no liability for indemnification under this Agreement shall be
       imposed upon the Indemnifying Party by reason of such claim.  The
       Indemnifying Party shall notify Claimant no later than ten (10) days
       after the date of the notice described in Section 7.5 of this Article 7
       of its intention to assume the defense of any such claims. In the event
       the Indemnifying Party fails to give such notice to Claimant within the
       said time, the Indemnifying Party shall no longer be entitled to assume
       such defense and the Claimant shall have the right to assume the defense
       thereof with counsel of its choice at the Indemnifying Party's expense
       and defend, settle or otherwise dispose of such claim. With respect to
       any such claim which the Indemnifying Party shall fail to defend
       promptly, said party shall not thereafter question the liability of the
       Indemnifying Party to Claimant for any loss or payment with respect to
       such claim (including attorneys' fees and cost of defense).

7.7    Determination of Loss.  The parties shall make appropriate adjustments
       ---------------------                                                 
       for tax benefits and insurance proceeds (reasonably certain of receipt
       and utility in each case) and for the time cost of money (using the
       Applicable Rate as the discount rate) in determining the amount of loss
       for purposes of this Article 7.  For the purpose of this Section 7.7 of
       this Article 7, "Applicable Rate" means the base rate published from time
       to time by Citibank N.A., New York, New York.

7.8    Consequential Damages.  Notwithstanding any provision of this Agreement
       ---------------------                                                  
       which might otherwise be to the contrary, neither party shall be liable
       to the other for lost profits or other consequential damages.

ARTICLE 8 -- NON-COMPETITION
- ----------------------------

8.1    Non-Competition.  In consideration of the transactions contemplated
       ---------------                                                    
       hereunder and other valuable consideration but subject to Section 5.5 of
       this Agreement, Roberts hereby covenants and agrees with Searle that
       Roberts and each of its Affiliates will not, between the Closing Date and
       the second (2nd) anniversary of the Closing Date, engage in, directly or
       indirectly, or carry on any business in the Territory in whatever form
       which shall consist of the manufacturing and/or packaging, distribution
       or sale of any ethical pharmaceutical product whose active ingredient(s)
       consist(s) solely of the same active ingredient(s) as the Product;
       provided that, nothing in this Article 8 shall in any way restrict or
       preclude Roberts or any of its Affiliates from acquiring another company,
       business or line of products (including by license thereof or through
       investment therein), a non-material portion of which includes such
       ethical pharmaceutical products. "Non-material" for purposes of this
       Article 8 means that ethical pharmaceutical products containing such
       active ingredients, account at the time of purchase for less than ten per
       cent (10%) of the gross sales in the Territory of all products included
       in the acquired company, business or line of products. If Roberts
       acquires any company, line of products or business with products as in
       (i) above, Roberts agrees to negotiate with Searle or Transferee, as
       applicable, toward a possible sale of such products to Searle or
       Transferee in the Territory.

                             DISTRIBUTION AGREEMENT
                             ----------------------


     This DISTRIBUTION AGREEMENT is entered into as of the ___ day of December,

     (a) Distributor accepts the foregoing appointment and agrees to provide all
of the usual and customary services of a distributor in the Territory, which
shall include, without limitation, the following:

          (i)  Distributor shall use all reasonable efforts to distribute and
          sell and diligently promote the Product in the Territory.  In this
          regard, Distributor shall provide and maintain a sales organization
          adequate to meet the needs of the market in the Territory.  Nothing in
          this Agreement shall be construed as requiring Distributor to maintain
          a sale organization outside the United States of America.

          (ii) Distributor agrees not to sell and distribute knowingly
          counterfeit Company products or Product which has been misbranded or
          adulterated or which is otherwise illicit.

          (iii) Distributor agrees to include the Product at frequent intervals
          in lists, bulletins or catalogs, as they may be issued by Distributor
          to its customers, and agrees to check such customers' supplies of
          Product regularly to insure adequate stocking and that the Product is
          in saleable condition.

          (iv) Distributor agrees not to sell the Product outside the Territory
          or knowingly sell the Product to customers in the Territory which
          intend to or who resell outside the Territory.

          (v) Distributor agrees to store and ship the Product strictly in
          accordance with the specifications in Exhibit B ("Specifications") and
          Company's instructions and as otherwise required by law.

          (vi) Distributor agrees not to make any warranty, guarantee, claim or
          representation in connection with the Product, unless authorized by

          Distributor.

          (vii) Distributor shall promptly provide Company with copies of any
          known Product related complaints of a medical nature, including
          adverse reaction and events, or product quality nature.

  (b) Nothing contained in this Agreement shall be construed to restrict
Company's right, in its sole discretion, after discussion with Distributor, to
discontinue manufacturing (or having the Product manufactured on its behalf) or
having the Product distributed within the Territory at any time, immediately
upon prior written notice to Distributor if in Company's reasonable scientific
or medical judgment (based upon medical or scientific reasons or on information
or circumstances not known or existing as of the date hereof by Company's senior
medical officer), further sale of the Product in the Territory is not advisable.

  (c) Distributor represents and warrants that it is not now selling and will
not during the term hereof sell in the Territory any products directly
competitive with the Product.  As used in this Section 2(c), "directly
competitive" means a magnesium supplement product.

  (d) Company represents and warrants that it will not during the term hereof,
and for a period of two (2) years after the expiration or earlier termination of
this Agreement other than termination by Company under Section 10(b), sell in
the Territory any products directly competitive with the Product.  As used in
this Section 2(d), "directly competitive" means a magnesium supplement product.
Nothing in this Section 2(d) shall in any way restrict or preclude Company or
any of its Affiliates from acquiring another company, business or line of
products (including by license thereof or through investment therein), a non-
material portion of which includes such magnesium supplement pharmaceutical
product.  "Non-material" for purposes of this Section 2(d) means that such
magnesium supplement product accounts at the time of purchase for less than ten
per cent (10%) of the gross sales in the Territory of all products included in
the acquired company, business or line of products.  If Company acquires any

conditions of this Agreement, except for quantity and delivery date terms which
may be specified in any purchase order hereunder; provided that, delivery shall
in no event be required in less than one hundred twenty (120) days from
Company's receipt of the applicable purchase order.  In the event of any
conflict, the terms of this Agreement shall prevail over those contained in
purchase orders or any other documents submitted by Distributor in connection
with this Agreement.  Concurrently with the execution of this Agreement,
Distributor will provide Company a forecast of estimated requirements for
Product during the following six (6) calendar quarters.  Distributor shall exert
all reasonable efforts to make each forecast as accurate as possible and shall
update such forecast at the end of each calendar quarter for the following six
(6) calendar quarters.  Company shall accept and fill orders to the extent they
do not exceed one hundred and twenty percent (120%) of Distributor's forecast
for the applicable calendar quarter and use all reasonable efforts to fill any
portion of such orders in excess of such amount.  Unless the parties
subsequently agree to the contrary, Company's obligation to supply Product shall
cease as of January 1, 2002.  If Company does not agree to extend its obligation
to supply Product as described above, Company will provide reasonable assistance

          facility at which the final packaging of the Product is completed,
          whether such facility is a Company facility, third party manufacturer
          facility, or, as is currently applicable, Distributor's facility (or
          such other shipping point as may be agreed between the parties),
          initially for the first twelve (12) months after the Effective Date at
          the prices specified in Exhibit C annexed hereto and made a part
          hereof. (ii) After the first twelve (12) months period in subsection

          Company notify Distributor of its desire to increase its price for the
          Product more than once in any one year during the term of this
          Agreement. The price which Distributor shall pay for the Product shall
          be that price in effect when an order for the Product is placed. The
          foregoing price increases shall include any increases in active
          ingredient costs or finished packaging costs charged by Distributor or
          its Affiliates ("Distributor Increases"), and such Distributor
          Increases shall not be subject to or included in determining the
          [DELETION] set forth above.

fully absorbed cost of the Product in sufficient detail so amounts payable

Distributor to whom Company has no reasonable objection, to examine said books
and records at reasonable times for the sole purpose of verifying the accuracy
of the written statements submitted to Distributor and the purchase price for
Product paid or payable.  Said independent accountants shall not disclose to
Distributor any information other than information relating solely to the

reports of any such inspections which directly relate to the Product, including
actions taken by Company to remedy conditions cited in such inspections.

                                      -16-

        (c)  Subject to Distributor's compliance with its obligations under this
Agreement, Company shall obtain and maintain all government license, permits and
registrations necessary for the Company's manufacturing, packaging and supply of
Product hereunder.

        (d)  Not more frequently than once each calendar year during the term
hereof, unless in an emergency situation, Company shall allow a representative
of Distributor (to whom Company has no reasonable objection) to inspect any
Company facility where the Product is manufactured and/or packaged, to assure
compliance with Company's obligations under this Agreement. Such inspection
shall be at reasonable times, following reasonable notice and be subject to such
confidentiality agreement and rules as Company shall designate from time to
time.

9.      Warranty, Indemnity and Inspection.
        ---------------------------------- 

        (a)  Company warrants, represents and covenants that, during the supply
period specified in Section 3(b) or any extension thereof,

             (i) on the date of shipment, no Product supplied hereunder shall be
             adulterated or misbranded within the meaning of the Federal Food,
             Drug and Cosmetic Act, as amended (the "Act"), or within the
             meaning of any applicable state or municipal laws in which the
             definitions of adulteration and misbranding are substantially the
             same as those contained in the Act, as the Act and such laws are
             constituted and effective at the time of shipment, or consist of or
             include any product or article which may not be introduced into
             interstate commerce; and

             (ii) Company shall have good title to all Product supplied
             hereunder, which title shall pass to Distributor as provided herein
             following payment therefor, free and clear of any lien, encumbrance
             or other conflicting interest of any kind, except as to any lien,
             encumbrance or conflicting interest arising with respect thereto as
             a result of any act or omission by Distributor.
<PAGE>
 
                                      -17-

(b)  THE WARRANTIES SET FORTH IN SECTION (a) ARE EXCLUSIVE AND IN LIEU OF ANY
     OTHER EXPRESS OR IMPLIED WARRANTY CONCENING THE PRODUCT, INCLUDING ANY
     IMPLIED WARRANTY OF FITNESS OR MERCHANTABILITY.

(c)  All Product ordered hereunder shall be subjected to a visual inspection
     upon receipt by Distributor.  All claims for shortages, alleged defects, or
     breaches of warranty which could be discovered by visual inspection shall
     be made in writing to Company no later than thirty (30) days 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, of recognized repute within
     the industry in the United States 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.  The cost of such determination shall be
     borne by the party against whom the decision is made.

(d)  Except as provided in Section 9(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 Distributor's (i) breach of
     this Agreement, or (ii) packaging, warehousing, handling, sale or promotion
     of the Product, as applicable, 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 
<PAGE>
 
                                      -18-

     out of or relating to Company's (i) breach of this Agreement or (ii)
     failure to supply Product complying with any of the Company's 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 Sections (b) and (c) of this Article 10, this Agreement shall be
     in effect for the period from the Effective Date until terminated pursuant
     to Section (b) below or as otherwise agreed by the parties.

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

        (i) the failure of the other party to comply with this Agreement in
        respect of any obligation, other than an obligation to make any payments
        under Sections 5(a) (ii), (iii) and (iv) hereof, 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, or
<PAGE>
 
                                      -19-

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

      or by the Company if,

        (iv) Distributor fails to make any payment under Sections 5(a) (ii),
      (iii) and (iv) hereof when due and such failure continues for a period in
      excess of thirty (30) days.

(c)  Upon termination of this Agreement for any reason, Distributor shall
     promptly return to Company all price lists, catalogs and other advertising
     literature furnished by Company and, if so requested by Company in writing,
     all Product on hand which is in good and saleable condition.  If so
     requested by Company, Company shall pay Distributor for such Product at
     Distributor's purchase price therefor under Section 3.  Upon termination of
     this Agreement for any reason, all related subdistributorship, agency or
     dealership agreements 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.

(d)  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, except as specifically provided in Section
     5(j).  Any pre-existing claims, however, shall not be waived by the parties
     as a result of such termination.

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 [DELETION].  All such insurance shall include Company as an
additional insured and must be issued by such insurer.
<PAGE>
 
                                      -20-

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 may not be amended
absent at least sixty (60) days notice to Distributor and Company.

12.  Current Product Supply Contracts.
     -------------------------------- 

Company shall, if requested by Distributor, use reasonable efforts (but 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.

13.  NDC Numbers and Medicaid Rebates.
     -------------------------------- 

(a)  Promptly following the Effective Date, Distributor shall take any and all
     action necessary to change the National Drug Code number ("NDC") for the
     Product, which change shall be implemented as reasonably agreed upon by the
     parties.

(b)  For purposes of Company's Rebate Agreement with the Secretary of Health and
     Human Services ("HHS") under Section 4401 of the Omnibus Budget
     Reconciliation Act of 1990, Company shall continue to make any Rebate
     Payment (as defined in such Rebate Agreement) with respect to the Product
     required thereunder; provided that, for Rebate Payments
<PAGE>
 
                                      -21-

     for which State Medicaid Utilization Information reports show that Medicaid
     payment was made for such drug after the Effective Date, Distributor shall
     promptly reimburse Company for all such Rebate Payments in accordance with
     Article 17 hereof.

(c)  Distributor shall notify all relevant persons and entities, including
     Company and First Data Bank, of such NDC change and comply with all laws
     and regulations of HHS or its sub-divisions and agencies (including HCFA)
     and the Rebate Agreement.

(d)  Distributor shall also provide Company all relevant information regarding
     Distributor's sales, promotion, pricing and other activities with respect
     to the Product, including pricing calculations for purposes of determining
     "Best Price", necessary for Company to comply with the Rebate Agreement.

14.  Returns of Product
     ------------------

     (a)  Returns will be the financial responsibility of the party that
          originally sold the returned Product.   Returns shall be tracked by
          lot number.  Returned Product with lot numbers sold exclusively by
          Company will be the financial responsibility of Company; returned
          Product with lots numbers sold exclusively by Distributor will be the
          responsibility of Distributor; financial responsibility for returned
          Product from lots where each party sold a portion of the lot will be
          prorated based on the portion of the shared lot that each party sold.

     (b)  Both parties agree to enforce preauthorized return or scan and destroy
          procedures in an attempt to have customer return Product and obtain
          credit from the party who originally sold the Product to them.  Both
          parties agree to accept returns from the prorated lot.  However,
          either party may accept Product returns for which they are not
          financially responsible in order to maintain their reputation and good
          will in the marketplace and the financially responsible party will
          reimburse the party processing the return.  In these cases, the
          processing party will verify the price the customer originally paid
          (and therefore the credit provided) with the party who originally sold
          the Product.

15.  Chargebacks and Rebates
     -----------------------

     (a)  Company will be financially responsible for all chargeback claims
          related to Product sold by a wholesaler to a chargeback contract
          customer on and after the Effective Date and during the first three
          (3) months of 1998.

     (b)  Company will be financially responsible for all managed care rebates
          related to Product dispensed by a pharmacist on and after the
          Effective Date and during the first six (6) months of 1998.

     (c)  In general, Distributor will forward to Company for payment any claims
          received related to Sections 15(a) and (b) above for which Company is
          financially responsible.  However, for the purpose of administrative
          convenience or at the specific request of a customer, Distributor may
          elect to pay the claim for which Company is financially responsible
          and Company will reimburse Distributor with respect to such claim.

     (d)  Company will be financially responsible for all Medicaid rebates
          related to Product dispensed by a pharmacist on and after the
          Effective Date and during the first six (6) months of 1998.  HCFA will
          continue to bill Company for Medicaid rebates for up to one year after
          the expiration date on the last Product issued with a Company labeler
          code.  For administrative convenience, Company will continue to pay
          all future Medicaid rebates claims it receives.  Distributor will
          reimburse Company for any rebate claims paid by Company but which
          relate to Product dispensed by a pharmacist after the aforesaid first
          six months of 1998.

     (e)  Company shall continue to make any chargeback or rebate payments with
          respect to the Product required under agreements, government mandates
          or otherwise which relate to supply contracts not assigned or
          assignable under Section 12 or which are processed by Company due to
          direct requests of a customer, provided that Distributor shall
          reimburse Company for all such payments pursuant to Section 17 below.

          customers and formularies under contracts existing as of the Effective
          Date of this Agreement that as of such date Distributor shall be the
          seller of the Product in the Territory (providing Distributor with a
          duplicate set of mailing labels for its use).

     (b)  invoice, book sales and ship Product as agent for Distributor and use
          all reasonable efforts (short of instituting third party collection or
          legal proceedings) to collect amounts due for Product so shipped.  For
          its services, Distributor shall pay Searle a fee equal to [DELETION],
          such fee to be paid in monthly installments within thirty (30) days of
          Company's invoice therefor.

17.      Quarterly Payments.  Company shall provide Distributor on a calendar

information necessary to calculate payments due under Sections 14 and 15(d) for
the calendar quarter just ended.  The payments due under these separate Sections
will be aggregated for each party and shall be made not later than sixty (60)

available funds to the bank and account designated from time to time in a notice
from Company.
