PART I

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 (908) 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

     For the fiscal year ended December 31, 1994, the Company reported, in a
note to the Company's consolidated financial statements, selected financial
information for the Company's two industry segments:  Product Sales and Contract
Clinical Research.  For the fiscal year ended December 31, 1994, Product Sales
and Contract Clinical Research had revenues of $95.1 million and $15.5 million,
respectively; operating income of $2.2 million and $42,000, respectively; and
identifiable assets of $327.9 million and $8.3 million respectively.  In March
1996, the Company announced that, in connection with the ongoing efforts of the
Company to achieve a more focused utilization of the Company's resources in its
core business of licensing, acquiring, developing and selling prescription
pharmaceutical products, it intended to discontinue and divest the business
comprising the Contract Clinical Research industry segment.  For the fiscal
years ended December 31, 1994, 1995 and 1996, the Company has reclassified its
consolidated financial statements to report separately the net assets expected
to be realized and the operating results of discontinued operations.
Accordingly, for the years ended December 31, 1995 and December 31, 1996, the
Company has not included separate selected financial information by industry
segments in the Company's consolidated financial statements.  See "Contract
Clinical Research" and "Notes to Consolidated Financial Statements - Note 16."

(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, Respiratory,
Gynecology/Endocrinology, Urology, Oncology, Hematology and Gastroenterology.

     The Company has a broad product portfolio including PROAMATINE(R), which is
the Company's first proprietary drug approved by the U.S. Food and Drug
Administration (the "FDA").  The second product to emerge from the Company's
pipeline, AGRYLIN(TM), has recently been approved by the FDA, and the Company
expects to begin actively promoting 

                                      -2-
<PAGE>
 
and marketing AGRYLIN in the second quarter of 1997. 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 1996, the Company continued the efforts commenced in 1995 which were
designed to concentrate the Company's business operations in its core business
of licensing, acquiring, developing and selling prescription pharmaceuticals.
While sales of nonprescription pharmaceutical products and the operations of
certain other nonpharmaceutical businesses, such as providing home and
outpatient medical care, marketing and selling medical products, and conducting
clinical research for other pharmaceutical companies, played important roles in
the initial stages of the Company's growth and development, the Company
determined that the continuation of such diverse operations was no longer
compatible with its principal objective of licensing, acquiring, developing,
marketing and selling prescription pharmaceutical products and moving the
Company's late-stage development drugs through the regulatory process.
Accordingly, in August 1995, the Company announced its decision to divest and
seek purchasers for certain non-core business activities, including certain
nonprescription pharmaceuticals, certain prescription pharmaceuticals, and its
home care and medical products divisions ("Homecare").  The Company has since
completed the sale of the core of its nonprescription pharmaceuticals and has 
essentially completed the sale of the Homecare operations. 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
actively seeking purchasers for 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 required to conduct post-
approval and post-launch (Phase IV) studies of PROAMATINE. PROAMATINE is in
Phase II trials for stress urinary incontinence. See "Late Stage Development
Products -Therapeutic Category - Urology."

                                      -3-
<PAGE>
 
     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.).

     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 and 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 expects to commence 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 suspected leukemogenesis, leukopenia and anemia.
Further, AGRYLIN has been designated by the FDA as being eligible for Orphan
Drug status.

     The Company has filed a New Drug Submission ("NDS") with the Health
Protection Branch, Canada ("HPB") for the sale of AGRYLIN in the Canadian
market, and the Company was recently notified that its NDS has been given
priority review status by the HPB.

     AGRYLIN is currently in pre-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 plans to file 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 and Australia/Asia 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 from various pharmaceutical companies.  These product 

                                      -4-
<PAGE>
 
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 expects to use to
market PROAMATINE and AGRYLIN as well as 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, NORETHIN(TM), an oral contraceptive agent, ETHMOZINE(R), NORPACE(R),
TRANDATE(R), SALUTENSIN(R), SALURON(R) and NITRODISC(TM), 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 its NUCOFED(R) and QUIBRON(R) lines of prescription respiratory products
to Monarch Pharmaceuticals, a division of King Pharmaceuticals, in October 1996.

     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; ENTROTABS(R), ENTEROSAN(R), 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.

     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.  The Company divested a substantial 
portion of its nonprescription products during the fourth quarter of 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 and PERI-COLACE, 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.

                                      -5-

     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.  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.

     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.

     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.

     In March, 1997, the Company and Pfizer Inc. (Pfizer) entered into a License
Agreement pursuant to which the Company acquired from Pfizer certain 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.


                                      -6-
<PAGE>
 
     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 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 anticipates filing an NDA
for MAXIVENT in 1997.  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.



                                      -7-
<PAGE>
 
     The Company currently markets the product SUPPRELIN(R) (histrelin), an
Orphan Drug, for central precocious puberty.  See "Government Regulation."  The
Company believes that SOMAGARD will complement SUPPRELIN.  A depot formulation
of SOMAGARD is being developed which will require less frequent injections.
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(TM) (SN-mesoporpyrin), 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 1997.

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

     The Company intends to contract-out the development of several of its late
stage development products, utilizing contract clinical research organizations.

     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 License Agreement.  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, make an
additional payment upon FDA approval and pay royalties on sales of the drug.

     In 1994, the Company entered into a distribution agreement with Swedish
Orphan AB ("Swedish Orphan") for the distribution and sale of AGRYLIN in the
Nordic countries of Norway, Sweden, Finland, Denmark and Iceland.  AGRYLIN is
not yet approved in the Nordic countries and, as part of the distribution
agreement, Swedish Orphan is responsible for obtaining regulatory approval.  If
regulatory approval is obtained, the Company will supply finished goods to
Swedish Orphan which will provide physical distribution along with marketing and
sales support.

     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.



                                      -10-
<PAGE>
 
     In 1993, the Company entered into an agreement with two Japanese
pharmaceutical companies, Sawai Pharmaceutical Co., Ltd. and Grelan
Pharmaceutical Co., Ltd., pursuant to which the Company granted such companies
exclusive rights to co-develop doxofylline in Japan.  The agreement was entered
into after the two Japanese pharmaceutical companies exercised an option to
acquire such rights previously granted to them by the Company.

     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 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.


                                      -11-
<PAGE>

 
     License Agreements for Tazofelone and other Lilly Compounds.  During the
     ------------------------------------------------------------            
fourth quarter of 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 Stated 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 licensed to the
Company pursuant to these License Agreements.

     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 nonexclusive license upon the
making of certain payments to the Company.

     MARKETING

     The Company markets and sells its products primarily through its own sales
force and through a network of brokers and distributors.  In 1995, the Company's
marketing and sales force increased by more than 50% in order to promote
actively the Company's products, mainly in connection with the commencement of
the sale of TIGAN, EMINASE and NOROXIN.  During 1996, the Company's sales force
continued to concentrate on selling TIGAN, EMINASE and NOROXIN, for the most
part, and establishing the groundwork for selling PROAMATINE and AGRYLIN.

     The Company has positioned its sales operation to impact selected physician
specialties and major buying and decision making entities, such as managed care
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 



                                      -12-
<PAGE>
 
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 has established 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 has established 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
October 1996, the Company agreed with Monsanto Canada, Inc. to acquire a 100,000
square foot pharmaceutical manufacturing facility currently operated by
Monsanto's Searle Division ("Searle") located in Oakville, Ontario.  The
facility which is currently operated by Searle 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 expects
that by transferring certain product manufacturing from third parties to its own
facility, the Company should realize certain benefits, including, without
limitation, lower production costs and more flexibility in determining
appropriate inventory levels for the Company's products.  In addition, the
Company plans to utilize 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, and the ability to obtain
regulatory approvals to transfer the manufacture of these products to Oakville.

     Upon finalizing the purchase of the facility, which the Company expects to
consummate by the middle part of 1997, Searle has agreed in principle to lease
back some space in the facility for a period of time as well as to have the
Company fulfill certain of Searle's product packaging requirements currently
being satisfied at the Oakville facility.  In addition, the Company will explore
the possibility of using the facility to engage in contract manufacturing for
other pharmaceutical companies until the facility is fully utilized by the
Company.

     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 

                                      -13-
<PAGE>
 
operations. The consummation of such agreement is pending as the parties seek
state regulatory approval for the transaction. See "Notes to Consolidated
Financial Statements - Note 16."

     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 1980 and 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. 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."

     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 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.  Beginning with the 1994
fiscal year, revenue from contract clinical research operations began to
decline, and in 1995, VRG's operations produced a loss, net of tax benefit, of
$3.5 million.  Among other reasons, the Company attributes such decline to the
completion of the work under agreements with Yamanouchi U.S.A. Inc., a
subsidiary of a major shareholder of the Company, and the fact that such work
was not replaced by other significant contracts. The Company is actively seeking
a purchaser for VRG's operations. See "Item 7 Management's

Discussion and Analysis of Financial Condition and Results of Operations" and
"Notes to Consolidated Financial Statements - Note 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 has been
granted Orphan Drug status and the FDA has designated each of SOMAGARD for
central precocious puberty and AGRYLIN for thrombocythemia, as being eligible
for Orphan Drug status in the United States.  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's 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 agreed to purchase from
Searle. See "Manufacturing." The Company's business is also subject to
regulation under the Occupational Safety and Health Act, the 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.


                                      -15-
<PAGE>
 
     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 19, 1997, the Company had 423 employees, including 5 officers,
66 persons engaged in research and development activities and 218 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 14 to the Company's financial statements.  See "Notes to Consolidated
Financial Statements - Note 14."

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.


                                      -16-
<PAGE>
 
     The Company has agreed to purchase from Searle a 100,000 square foot
manufacturing facility located in Oakville, Ontario which is currently operated
by Searle. The Company anticipates that the purchase of this facility will be
completed by the middle part of 1997. See "Item 1 Business -Manufacturing."

     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's Canadian subsidiary, Roberts Pharmaceutical Canada, Inc.,
occupies 4,122 square feet of leased office space in Ontario, Canada.  The lease
provides for a monthly rental of $4,122, Canadian currency.  If the Company
completes the purchase of the Oakville manufacturing facility, the Company
intends to consolidate its Canadian operations by closing this office and
relocating all personnel to the office space available in the manufacturing
facility.

     The Company also leases office space in several other locations in the
United States and certain foreign countries.

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 asserts 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 seeks 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 believes that it
has complied with all of its obligations under the federal securities laws and
considers the plaintiff's allegations to be without merit.  The Company is
vigorously defending against the allegations in this remaining suit and
discovery proceedings have commenced.  The Company is not able to predict the
outcome of this proceeding at this time, and management is not able to determine
the amount of the potential liability, if any.

     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 or
contemplated.

ITEM 5.   MARKET FOR THE REGISTRANT'S COMMON STOCK AND RELATED STOCKHOLDER
          MATTERS

COMMON STOCK

     The Company's Common Stock is traded in the over-the-counter market on the
NASDAQ National Market System and was held by approximately 900 shareholders of
record as of March 19, 1997.

     The following table sets forth, for the periods indicated, the high and low
last sale prices for the Company's Common Stock, as reported on the NASDAQ

</TABLE>
     The Company has not paid any cash dividends on its Common Stock in the
past, and it is unlikely that the Company will pay any dividends on its Common
Stock in the foreseeable future.

     Pursuant to the terms of the several Stock Purchase Agreements, each dated
as of 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
$9,990,000 (the "Common Stock Private Placement").  The identities of such
investors in the Common Stock Private Placement are incorporated herein by
reference to the section entitled "Selling Shareholders," which is included in
the Prospectus for the resale of shares of Common Stock which is part of the
Form S-3 Registration Statement which became effective on November 7, 1996 (the
"Registration Statement").

     Cappello & Laffer Capital Corp. was the Placement Agent (the "Placement
Agent") for the Common Stock Private Placement.  In consideration for placing
such securities, the Placement Agent received aggregate cash consideration in an
amount which is equal to 5% of the gross proceeds received by the Company and
was reimbursed for certain expenses.  Further, the Company issued to certain
designees of the Placement Agent, Common Stock Warrants to acquire an aggregate
of 15,000 shares of Common Stock for a purchase price of $16.65 per share, which
warrants expire in July 1999.

     The shares of Common Stock sold in the Common Stock Private Placement were
not registered at the time such private placement was consummated.  The Company
relied on the exemption from registration provided by Rule 506 under Regulation
D of the Securities Act of 1933, as amended ( the "Securities Act").  However,
all such shares of Common Stock have been subsequently registered pursuant to
the Registration Statement.

5% PREFERRED STOCK

     Pursuant to the terms of the several Preferred Stock Investment Agreements,
each dated as of 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 5% Preferred Stock resulting in gross proceeds
of $105 million (the "Preferred Stock Private Placement").  The identities of
the purchasers of the 5% Preferred Stock in the Preferred Stock Private
Placement are incorporated herein by reference to the section entitled "Selling
Shareholders" included in the Registration Statement.

     The Placement Agent placed the shares of 5% Preferred Stock sold in the
Preferred Stock Private Placement.  The Placement Agent received aggregate cash
consideration of 5% of the gross proceeds received by the Company and was
reimbursed for certain expenses.  Further, the Company issued to certain
assignees of the Placement Agent Convertible Preferred Stock Warrants to acquire
420,000 shares of 5% Preferred Stock for a purchase price of $25.00 per share,
which warrants expire in August, 1998.

     The shares of 5% Preferred Stock were not registered and were sold pursuant
to the exemption from registration provided by Rule 506 under Regulation D of
the Securities Act.  However, a certain number of shares of Common Stock into
which the shares of 5% Preferred Stock could be converted have been registered
pursuant to the Registration Statement.

     The Company is not aware of any established public trading market for the
shares of 5% Preferred Stock and none is expected to develop.  Dividends at the
rate of $1.25 per share per annum are payable quarterly on the 5% Preferred
Stock.  Such dividends may be paid in cash or, at the option of the Company and
subject to certain conditions, in shares of 5% Preferred Stock.  For the year
1996, the Company paid and accrued dividends on the 5% Preferred Stock in an 
aggregate amount equal to $1,285,716. The 5% Preferred Stock is also subject to
a liquidation preference of $25.00 per share (plus accrued and unpaid dividends
thereon) (the "Liquidation Preference").

     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
conversion.  The conversion price is equal to 90% of the lowest trade price of
the Common Stock as reported by the NASDAQ National Market System during a
specified period of trading days (the "Conversion Price") and, accordingly, the
number of shares of Common Stock will vary inversely with the market price of
the Common Stock.  In any event, the Conversion Price shall not be greater than
$19.1359 (the "Conversion Cap").  The number of shares of Common Stock which a
holder of shares of 5% Preferred Stock may acquire upon the conversion of such
shares shall be determined by dividing the Liquidation Preference by the
Conversion Price on the date the notice of conversion is given by the holder.

     At any time on or after August 29, 1997, the Company at its option may
cause all outstanding shares of 5% Preferred Stock to be converted into Common
Stock at the Conversion Price as of the date specified in the Company's notice;
provided, that the 

                                      -21-
<PAGE>
 
Company may not exercise such right of conversion unless (i) the closing price
of the Common Stock as reported by the NASDAQ National Market System for the 20
consecutive trading days prior to the date the conversion notice is mailed has
not on any day been less than 120% of the Conversion Cap, and (ii) the shares of
Common Stock issuable upon conversion are registered for resale by an effective
registration statement under the Securities Act and a current prospectus is
available for delivery.

     On August 20, 1998, any outstanding shares of 5% Preferred Stock shall be
automatically converted into shares of Common Stock at the Conversion Price on
such date.

     As of March 19, 1997, there were 1,004,622 shares of 5% Preferred Stock
outstanding and 27 holders of such 5% Preferred Stock.  3,195,378 shares of 5%
Preferred Stock have been converted into 7,962,619 shares of Common Stock.

(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, in
     accordance with FASB Statement No. 121, "Accounting for the Impairment of
     Long-Lived Assets and for Long-Lived Assets to Be Disposed Of," the Company
     recorded an impairment loss of long-lived intangible assets in the amount
     of $25.4 million, which amounted to $17.8 million net of taxes.


                                      -23-
<PAGE>

     Operating income and net loss were negatively affected by 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, operating income would have amounted to a
     loss of $12.9 million and net loss would have been $8.3 million.

(2)  Pursuant to a new 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 5%
     Preferred 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 write-off 
     and the sale of intangible assets, the 
     recognition of the discount upon the  
     issuance of 5% Preferred Stock or

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

RESULTS OF OPERATIONS

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 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 decreased from
     -------------------------                                                  
$6.1 million in 1995 to $4.0 million in 1996, a decrease of 34.4%.  This
decrease results from decreased expenditures in the development of the Company's
two recently approved products, AGRYLIN and PROAMATINE. The Company anticipates
increased research and development expenses in 1997 relating primarily to the
continued development of MAXIVENT, DIRAME, STANATE and the Lilly Compound,
LY315535.

     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 

                                      -25-
<PAGE>
 
$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.

     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.

     The Company has recorded deferred tax assets of approximately $20.3
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.

     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, in accordance with FASB Statement No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of,"
the Company recorded an impairment loss of long-lived intangible assets in the
amount of $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.

     New Accounting Pronouncements.  In February 1997, the Financial Accounting
     ------------------------------                        
Standards Board ("FASB") issued Statement of Financial Accounting Standards
("SFAS") No. 128, "Earnings Per Share."  SFAS 128 specifies new standards
designed to improve the earnings per share ("EPS") information provided in
financial statements by simplifying the existing computational guidelines,
revising the disclosure requirements, and increasing the comparability of EPS
data on an international basis.  Some of the changes made to simplify the EPS
computations include:  (a) eliminating the presentation of primary EPS and
replacing it with basic EPS, with the principal difference being that common
stock equivalents are not considered in computing basic EPS, (b) eliminating the
modified treasury stock method and the three percent materiality provision, and
(c) revising the contingent share provisions and the supplemental EPS data
requirements. SFAS 128 also makes a number of changes to existing disclosure
requirements. SFAS 128 is effective for financial statements issued for periods
ending after December 31, 1997, including interim periods. The Company has not
yet determined the impact of the implementation of SFAS 128.

     See "Notes to Consolidated Financial Statements - Note 16" for a discussion
of discontinued operations.

RESULTS OF OPERATIONS

YEARS ENDED DECEMBER 31, 1994 AND 1995

     Corporate Revenues.  For the year ended December 31, 1995, total revenue
     -------------------                                                     
increased $24.4 million from $89 million to $113.4 million.  This increase was
the result of a $26 million increase in product revenue offset by a $1.50
million decrease in other revenues.  See "Product Sales" and "Other Revenues."

     Product Sales.  For the year ended December 31, 1995, product sales
     --------------                                                     
increased $26 million from $87.4 million to $113.4 million primarily as a result
of new product acquisitions in the U.S. and the United Kingdom in 1994 and 1995.
Sales in the U.S. increased from $66.2 million to $90.2 million as a result of
1995 product acquisitions and licensing activities.  TIGAN and EMINASE, acquired
from SmithKline Beecham, and NOROXIN licensed from Merck in 1995, added $48
million.  This increase was offset by a $24 million decline in the sales of all
other prescription and nonprescription products.  Sales of the Company's United
Kingdom subsidiary, Monmouth Pharmaceuticals, Ltd., increased $2.4 million from
$9.7 million to $12.1 million.  This increase is primarily the result of the
1994 product acquisition of MAXOLON from SmithKline Beecham.  Sales of the
Company's Canadian subsidiary, Roberts Pharmaceutical Canada, Inc., decreased
slightly to $11.1 million from $11.4 million primarily as a result of a decline
in demand for the Company's nonprescription pharmaceutical products.

     Other Revenues.  Other revenues resulted from licensing activities 
     ---------------                                                            
undertaken by the Company and represented revenues from separate transactions in
1994 and 1995. For the year ended December 31, 1995, other revenues decreased
$1.55 million from $1.6 million to $.05 million primarily as a result of a
decline in licensing activities.

     Cost of Sales.  For the year ended December 31, 1995, cost of sales
     --------------                                                     
amounted to 47% of product sales, a 25 percentage point increase as compared to
the prior year.  As a result, gross profit as a percentage of sales decreased
from 78% to 53%.  This increase in cost of sales as a percentage of product
sales and the related decrease in gross profit percentage was primarily the
result of the addition of NOROXIN to the Company's product mix as well as a
decline in sales of higher margin products in the U.S.  NOROXIN, which accounted
for 31% of the Company's product sales in 1995, has a significantly lower gross
profit margin than the other core pharmaceutical products sold by the Company.
In the foreseeable future, the Company expects that NOROXIN will continue to
provide a substantial part of the Company's product sales and, accordingly, the
Company expects that cost of sales and gross profit as a percentage of sales
will be similarly impacted.

     Research and Development.  Research and development expenses decreased by
     -------------------------                                                
$3.4 million to $6.1 million during the year ended December 31, 1995 as compared
to the prior year.  The decrease was due to a reduced level of expenditure
required to support the Company's development programs for AGRYLIN and
PROAMANTINE.
 
     Marketing and Administrative Expenses.  For the year ended December 31,
     --------------------------------------                                 
1995, marketing and administrative expenses increased $13.3 million from $34.3
million to $47.6 million in large part as a function of the significant
increases in sales and development programs in connection with the acquisition
and commencement of sales of TIGAN, EMINASE and NOROXIN during 1995.  Marketing
expenses increased $7.4 million as a result of increased promotional and sales
activities for new products and the expansion and training of the Company's
sales forces in the U.S., Canada and the United Kingdom.
 
                                      -27-
<PAGE>
 
Included in administrative expenses is amortization of intangibles relating to
product acquisitions. For the year ended December 31, 1995, this expense was
$6.6 million, an increase of $.9 million from $5.7 million recorded in 1994.

     Interest Income and Expense.  For the year ended December 31, 1995,
     ----------------------------                                       
interest income decreased from $2.9 million to $2.1 million as a result of a
decrease in invested marketable securities.  Interest expense decreased from
$3.9 million to $3.5 million primarily as a result of a decrease in long-term
debt from 1994.

     Income Taxes.  For the year ended December 31, 1995, income taxes on
     -------------                                                       
continuing operations decreased to $2.8 million from $4.1 million in 1994
primarily as a result of a decline in income.  The Company's 1995 effective tax
rate of 51% was higher than the normal statutory rate primarily as a result of
the Company's inability to recognize the tax benefit of Canadian net operating
loss carryforwards.

     Income from Continuing Operations.  For the year ended December 31,1995,
     ----------------------------------                                      
net income from continuing operations was $2.7 million, which represents a
decrease of $17.9 million of income from those same business operations during
1994.

     The Company believes that the decline in net income from continuing
operations from 1994 to 1995 was attributable to a number of factors, including
(i) a decline in demand for certain of the Company's existing pharmaceutical
products, particularly NORETHIN, NITRODISC, SALUTENSIN and the Company's over-
the-counter nonprescription pharmaceutical products; (ii) an unanticipated delay
in the closing of the Company's agreement with Merck to distribute NOROXIN and
the diversion of the Company's sales force from the promotion of existing
products to allow for sales training related to NOROXIN; (iii) revenues from the
sale of TIGAN and EMINASE during the first quarter of 1995 prior to their
acquisition by the Company, during which time the Company was distributing such
products subject to distribution agreements with SmithKline Beecham, were not
accounted for as revenues by the Company, but instead as a $5.4 million
reduction in the purchase price paid by the Company for these products; (iv) the
increase in cost of sales as a result of the higher costs related to the sale of
NOROXIN and the growing importance of NOROXIN in the Company's product mix; and
(v) the costs associated with increasing the Company's sales force by more than
50% in 1995 in order to promote TIGAN, EMINASE and NOROXIN and the fact that the
sale of such products did not commence until the end of the first quarter of
1995.

     Discontinued Operations.  In connection with the Company's decision to
     ------------------------                                              
divest certain non-core, nonpharmaceutical business operations, the Company
announced, in August 1995, its plan to discontinue and divest Homecare. In March
1996, the Company announced its plan to discontinue and divest VRG, a contract
research organization. The Company's reported loss on discontinued operations
represents the Company's best estimates of the amounts expected to be realized
on the sale of its discontinued operations. The amounts the Company will realize
could differ materially from those amounts assumed by the Company in estimating
the loss on disposal reported in the Company's financial statements. For the
year ended December 31, 1995, the Company reserved $9.7 million for anticipated
losses relating to the discontinuation of its Homecare business. The sale of
Homecare was essentially completed in 1996 resulting in a net charge to the
reserve of approximately $1 million. For the fiscal year ended December 31,
1995, the Comapny reserved $12.8 million for anticipated losses relating to the
discontinuation of VRG. In 1996, the Company revised its estimate of anticipated
losses relating to VRG and reduced its reserve for such losses by $3.1 million.
See "Notes to Consolidated Financial Statements--Note 16."

LIQUIDITY AND CAPITAL RESOURCES

     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 totalling $25.4 million.
As of December 31, 1996, the Company had cash, cash equivalents and marketable
securities of $94.9 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. Cash inflows from operations amounted to $22.8 million in 1995 and
cash outflows from operations amounted to $0.7 million in 1994.

     The Company's funding requirements will depend on a number of factors,
including the Company's development programs, product acquisitions, the level of
resources required for the expansion of marketing capabilities, especially
relating to the Company's two recently approved 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 with parties to collaborative agreements, the success of
acquisition activities, the revenues generated from sales of PROAMATINE and
AGRYLIN, and funding required to finalize the purchase of a fully equipped
pharmaceutical manufacturing facility from Searle, which is expected to occur in
mid 1997.

     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
expenditures 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 1994 relate primarily to the
     ---------------------                                                      
relocation of the Company's operating facilities in 1993.  The Company has
agreed to purchase a fully equipped pharmaceutical manufacturing facility from
Searle for $6.3 million (Canadian) which is expected to be finalized in mid
1997.  The Company anticipates additional capital expenditures in 1997 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.  For the year ended December
31, 1996, the Company had a foreign exchange net gain of $0.4 million as a
result of translating Monmouth Pharmaceuticals Ltd.'s net assets.

     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 receivables.  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.

                       Report of Independent Accountants
                       ---------------------------------

To the Board of Directors and Shareholders 
of Roberts Pharmaceutical Corporation:

        We have audited the accompanying consolidated balance sheets of Roberts
Pharmaceutical Corporation and Subsidiaries as of December 31, 1996, 1995 and
1994, 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, 1996 and the financial statement schedules on pages F-26 to F-28 on 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, 1996, 1995 and
1994, and the consolidated results of their operations and their cash flows for
each of the three years in the period ended December 31, 1996 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.

                  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 market.

     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
<PAGE>
 
                      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 a permanent impairment in the value of
     intangibles.

     The Company adopted Statement of Financial Accounting Standards (SFAS) No.
     121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
     Assets to Be Disposed Of," effective first quarter 1996. Upon adoption of
     SFAS No. 121, there was no material impact on the Company. SFAS No. 121
     requires impairment losses to be recognized for long-lived assets and
     certain identifiable intangible assets used in operations when indicators
     of impairment are present and the undiscounted future cash flows are not
     expected to be sufficient to recover the assets' carrying amount. In the
     fourth quarter of 1996, after the Company had reassessed the effect of SFAS
     No. 121, the Company recorded a charge to earnings of $25.4 million for an
     impairment of intangible assets.

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

     The functional currency of the Company's European subsidiary is the U.S.
     dollar.  Accordingly, its accounts are 

                                      F-8

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

     remeasured in dollars and translation gains and losses are included in
     income currently.

     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, 1994, 1995 and 1996 is debt
     of $4,673, $1,849 and $832, 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, 1994, 1995
     and 1996, the reserve for uncollectible accounts amounted to $2,195, $1,754
     and $1,440, respectively.

     At December 31, 1996, 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 $7,672 at December 31, 1996. These investment securities mature
     within one year.

     Income (loss) per share
     -----------------------
     
     Income (loss) per share was computed based on the weighted average number
     of shares of Common Stock actually outstanding plus the number of shares of
     Common Stock that lowercase would be outstanding assuming the exercise of
     dilutive stock options. In 1996, the 5% Preferred Stock dividends and the
     10% discount to market upon conversion of the 5% Preferred Stock into
     Common Stock were included in the calculation.

     Pursuant to a new 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 Earnings Per
     Share by $.61 per share. This reflects the Staff's position that the 10%
     discount available to holders of the Company's

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


     5% Preferred Stock should be incorporated in the calculation of Earnings
     Per Share.

     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 write-off
     and the sale of intangible assets, the
     recognition of the discount upon the 
     issuance of 5% Preferred Stock or

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

     In February 1997, the Financial Accounting Standards Board ("FASB")
     issued Statement of Financial Accounting Standards ("SFAS") No. 128,
     "Earnings Per Share." SFAS 128 specifies new standards designed to improve
     the earnings per share ("EPS") information provided in financial statements
     by simplifying the existing computational guidelines, revising the
     disclosure requirements, and increasing the comparability of EPS data on an
     international basis. Some of the changes made to simplify the EPS
     computations include: (a) eliminating the presentation of primary EPS and
     replacing it with basic EPS, with the principal difference being that
     common stock equivalents are not considered in computing basic EPS, (b)
     eliminating the modified treasury stock method and the three percent
     materiality provision, and (c) revising the contingent share provisions and
     the supplemental EPS data requirements. SFAS 128 also makes a number of
     changes to existing disclosure requirements. SFAS 128 is effective for
     financial statements issued for periods ending after December 31, 1997,
     including interim periods. The Company has not yet determined the impact of
     the implementation of SFAS 128.

    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, in accordance with FASB Statement No. 121, "Accounting for the
    Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
    Of," the Company recorded an impairment loss of long-lived intangible assets
    in the amount of $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.

    Operating income and net loss were negatively affected by 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
    sale and write down had not occurred.

8.  SHAREHOLDERS' EQUITY
    --------------------

    The Company has adopted the disclosure-only provisions of SFAS No. 123,
    "Accounting for Stock-Based Compensation," but applies Accounting 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 and 1996, consistent
    with the provisions of SFAS No. 123, the Company's net loss and per share
    data would have been changed to the pro forma amounts indicated below:

                              ---------  

    The fair value of stock options used to compute pro forma net loss and per
    share disclosures is the estimated present value at grant date using the
    Black-Scholes option-pricing model with the following weighted average
    assumptions:  dividend yield of 0%; expected volatility of 57%; 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, 1995 and 1996 was $5.31 and $ 7.17, 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 $9,900. 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 5% Preferred

    Stock resulting in gross proceeds of $105,000. 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. 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.


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

    During 1996, 1995 and 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 of the Company's Board of Directors, provided that no incentive
    stock options, 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.

    At December 31, 1996, the Company has federal net operating loss
    carryforwards of approximately $26,400 which expire in the year 2011,
    foreign net operating loss carryforwards of approximately $7,500 and net
    operating loss carryforwards for state tax purposes of approximately $62,282
    which expire at various dates through 2003.

    A full 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 deferred tax assets of approximately $20.3 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.

10. 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 fiscal years
    required under leases which have

    In accordance with several product acquisitions and licensing agreements and
    subject to certain cancellation rights reserved by the Company, the Company
    may be required to purchase inventory or make minimum payments totalling
    $34,800 through 2001 and make royalty payments totalling $1,878 through
    1998.

    The Company has agreed to purchase a fully equipped pharmaceutical
    manufacturing facility from Searle for $6.3 million (Canadian) which is
    expected to be finalized in mid 1997.

11. EMPLOYEE BENEFITS
    -----------------

    The Company has employment agreements with certain of its employees which
    provide them with continued compensation for a period of two to five years
    in the event of their termination by the Company and provide certain of them
    with additional payments on termination by the Company equal to three to
    five times a portion of their average bonus and incentive compensation from
    July 1, 1988 to their termination date.

    The Company maintains an employee savings plan available to all employees
    who meet certain age and service requirements and may make discretionary
    contributions to the plan based on employee compensation or employee
    contributions.  In the years ended December 31, 1994, 1995 and 1996, the
    Company contributions amounted to $220, $231 and $197, respectively.

    The Company has a money purchase pension plan available to all employees who
    meet certain age and service requirements. The Company makes discretionary
    contributions to the plan based on employee compensation, and the Company
    can choose to terminate the plan at any time. In 1994, 1995 and 1996, the
    Company recorded contributions amounting to $0, $217 and $206, respectively.

    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 NASDAQ Stock Market on that date. 500,000 shares of the Company's
    Common Stock have been reserved for issuance under the Employee Stock
    Purchase Plan.

12. CONTINGENCY
    -----------

    A shareholder class action suit has been instituted in the United States
    District Court for the District of New Jersey against the Company and
    certain of its officers for alleged violations of certain federal securities
    laws.  The Company is not able to predict the outcome of this proceeding at
    this time, and management is not able to determine the amount of the
    potential liability, if any.  The Company believes that it has complied with
    all of its obligations under the federal securities laws.  The Company
    intends to defend vigorously against the plaintiff's allegations and
    considers such allegations to be without merit.

13. ACQUISITIONS
    ------------

    In 1994, 1995 and 1996, the Company acquired inventory, trademarks and other
    rights to several products from various pharmaceutical companies.  The
    aggregate price of these acquisitions was $21,996, $22,254 and $8,052,
    respectively, consisting of cash and notes payable.  The intangibles related
    to acquisitions are being amortized on the straight-line basis over periods
    ranging from twenty-five to forty years.

15. RELATED PARTY TRANSACTIONS
    --------------------------

    In 1992 and 1993, the Company entered into contracts with Yamanouchi U.K.
    Limited, a subsidiary of Yamanouchi Pharmaceutical Co., Ltd. of Japan, for
    clinical trials research.  These contracts have subsequently been assigned
    to Yamanouchi U.S.A. Inc., a subsidiary of Yamanouchi. As of December 31,
    1994, 1995, and 1996, Yamanouchi owned 27.5, 27.2 and 22.0 percent of the
    Company's outstanding Common Stock, respectively.  At December 31, 1994 and
    1995, accounts receivable and unbilled revenues from these contracts
    totalled $7.3 million, and $.6 million, respectively.  Related revenues in
    the years 1994 and 1995 amounted to $10.2 million and $.5 million,
    respectively.  With the Company's decision to dispose of the contract
    research division, these revenues have been reclassified and reported in
    results from discontinued operations.  In March 1995, the Company resolved a
    contract interpretation issue with Yamanouchi concerning billings for costs
    incurred by the Company under the clinical research contracts.  As a result,
    1994 contract research revenue and operating income were reduced by
    approximately $2.4 million. Net income for 1994 was reduced by approximately
    $1.5 million.

16. 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.

    At December 31, 1995, net assets expected to be realized, consisting
    primarily of inventory, receivables, plant and equipment, totaled $3.8
    million.

    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.

                      ROBERTS PHARMACEUTICAL CORPORATION
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


    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.  As of
    December 31, 1996 the Company is still seeking a buyer for the VRG division.

    Revenues from VRG and Homecare for the years ended December 31, 1994 and
    1995 were $23.2 million and $12.5 million, respectively.

17. 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.

          Preferred value at $25 per share if the Common Stock issuable upon
          conversion of such shares has been registered for resale under the
          Securities Act of 1933, as amended (the "Act"), and the registration
          statement including a current prospectus with respect thereto remains
          in effect at the date of delivery of such shares, and if the
          Corporation shall have given written notice of its intention to pay
          such dividend in stock to all holders of the 5% Preferred at least 10
          days before the record date for such dividend. No holder that is a
          bank holding company or subsidiary thereof shall be required to accept
          5% Preferred in lieu of cash in payment of a dividend unless after
          giving effect thereto the provisions of Section 10 hereof would permit
          one share of 5% Preferred to be converted by such holder.

2.   Liquidation Preference.
     -----------------------

     a)   In the event of any liquidation, dissolution or winding up of the
          Corporation, either voluntary or involuntary, the holders of the 5%
          Preferred shall be entitled to receive, prior and in preference to any
          distribution of any assets of the Corporation to the holders of any
          other class or series of shares, the amount of $25 per share plus any
          accrued but unpaid dividends (the "Liquidation Preference").

     b)   A consolidation or merger of the Corporation with or into any other
          corporation or corporations, or a sale of all or substantially all of
          the assets of the Corporation, shall, at the option of the holders of
          the 5% Preferred, be deemed a liquidation, dissolution or winding up
          within the meaning of this Section 2 if the shares of stock of the
          Corporation outstanding immediately prior to such transaction
          represent immediately after such transaction less than a majority of
          the voting power of the surviving corporation (or of the acquiror of
          the Corporation's assets in the case of a sale of assets).  Such
          option may be exercised by the vote or written consent of holders of a
          majority of the 5% Preferred at any time within thirty calendar days
          after written notice (which shall be given promptly) of the essential
          terms of such transaction shall have been given to the holders of the
          5% Preferred in the manner provided by law for the giving of notice of
          meetings of shareholders.

3.   Forced Conversion.
     ------------------

     a)   The Company at its option may cause all outstanding shares of the 5%
          Preferred to be converted into Common Stock at any time beginning
          twelve months after the date of issuance, on at least 20 days' notice,
          at a conversion price determined as set forth in Section 4  hereof
          (the "Conversion Price") as of the date specified in such notice (the
          "Conversion Date") and otherwise on the terms set forth in said
          Section 4; provided, that the Corporation may not exercise such right
          of conversion unless (i) the Closing Price (last trade price) of the
          Common Stock as reported by NASDAQ for the 20 consecutive trading days
          prior to the date the Conversion Notice is mailed has not on any day
          been less than 120% of the Conversion Cap (as defined in Section
          4(c)(ii) hereof)(subject to adjustment for stock dividends, stock
          splits and reverse stock splits), and (ii) the shares issuable upon
          conversion of the 5% Preferred are registered for resale by an
          effective registration statement ("Registration Statement") under the
          Act which became effective not more than 90 days after the date of
          issuance of the 5% Preferred, and a current prospectus meeting the
          requirements of Section 10 of the Act is available for delivery at the
          Conversion Date.

     b)   At least 20 days prior to the Conversion Date, written notice (the
          "Conversion Notice") shall be mailed, first class postage prepaid, by
          the Corporation to each holder of record of the 5% Preferred, at the
          address last shown on the records of the Corporation for such holder,
          notifying such holder of the conversion which is to be effected,
          specifying the Conversion Date and calling upon each such holder to
          surrender to the Corporation, in the manner and at the place
          designated, a certificate or certificates representing the number of
          shares of 5% Preferred held by such holder.  Subject to the provisions
          of the following subsection (c), on or after the Conversion Date, each
          holder of 5% Preferred shall surrender to the Corporation the
          certificate or certificates representing the shares of 5% Preferred
          owned by such holder as of the Conversion Date, in the manner and at
          the place designated in the Conversion Notice, and thereupon the
          shares issuable upon such conversion shall be delivered as provided in
          Section 4(b) hereof.

                                      -3-
<PAGE>
 
     c)   If at the Conversion Date the registration condition specified in
          clause (ii) of subsection (a) shall not be satisfied, then no shares
          shall be converted and the Conversion Notice shall be deemed to be
          withdrawn.  In such event, any certificates for 5% Preferred which
          have been surrendered for conversion shall be returned to the persons
          surrendering the same; provided, however, that if a holder shall have
          received shares of Common Stock upon conversion of 5% Preferred after
          the Conversion Notice was given but before the Conversion  Date, such
          holder may elect either to retain such Common Stock or rescind such
          conversion by tendering such shares of Common Stock to the
          Corporation.

     d)   On the second anniversary of the Closing Date, all then outstanding
          shares of 5% Preferred shall be automatically converted into Common
          Stock at the Conversion Price and otherwise pursuant to the applicable
          provisions set forth in Section 4 hereof.

4.   Optional Conversion.  The holders of the 5% Preferred shall have optional
     --------------------                                                     
     conversion rights as follows:

     a)   Right to Convert.  At any time after the earlier of (i) the date at
          -----------------                                                  
          which a Registration Statement is declared effective, or (ii) the 90th
          day following the Closing Date, each share of 5% Preferred shall be
          convertible, at the option of the holder thereof, into such number of
          fully paid and nonassessable shares of Common Stock as is determined
          by dividing (x) the Liquidation Preference of the 5% Preferred
          determined pursuant to Section 2 hereof on the date the notice of
          conversion is given, by (y) the Conversion Price determined as
          hereinafter provided in effect on said date.

     b)   Mechanics of Conversion.  To convert shares of 5% Preferred into
          ------------------------                                        
          shares of Common Stock, the holder shall give written notice to the
          Corporation (which notice may be given by facsimile transmission) that
          such holder elects to convert the same and shall state therein the
          number of shares to be converted and the name or names in which such
          holder wishes the certificate or certificates for shares of Common
          Stock to be issued.  Promptly thereafter the holder shall surrender
          the certificate or certificates representing the shares to be
          converted, duly endorsed, at the office of the Corporation or of any
          transfer agent for such shares, or at such other place designated by
          the Corporation.  The Corporation shall,

                                      -4-
<PAGE>
 
          immediately upon receipt of such notice, issue and deliver to or upon
          the order of such holder, against delivery of the certificates
          representing the shares which have been converted, a certificate or
          certificates for the number of shares of Common Stock to which such
          holder shall be entitled. The Corporation shall effect such issuance
          within two (2) business days and shall transmit the certificates by
          messenger or overnight delivery service to reach the address
          designated by such holder within two (2) business days after the
          receipt of such notice. Notice of conversion may be given by a holder
          at any time during the day up to midnight New York time and such
          conversion shall be deemed to have been made immediately prior to the
          close of business on the date such notice of conversion is given. The
          person or persons entitled to receive the shares of Common Stock
          issuable upon such conversion shall be treated for all purposes as the
          record holder or holders of such shares of Common Stock at the close
          of business on such date.

     c)   Determination of Conversion Price.
          ----------------------------------

          i)   At any date following the earlier of (x) the date at which a
          Registration Statement is declared effective, or (ii) the 90th day
          following the Closing Date subject to the provisions of subparagraph
          (ii) below, the Conversion Price shall be 90% of the lowest trade
          price of the Common Stock as reported by NASDAQ during a specified
          period of consecutive trading days immediately preceding such date,
          which periods are set forth in the table below:

         Period during which such        Period of consecutive trading
         date occurs:                    days preceding such date:

         Through the 120th day after Closing        5 days
         121st to 150th day after Closing           6 days
         151st to 180th day after Closing           7 days
         181th to 210th day after Closing           8 days
         211th to 240th day after Closing           9 days
         241st to 270th day after Closing          10 days
         271st to 300th day after Closing          11 days
         301st to 330th day after Closing          12 days
         331st day after Closing or later          13 days

          ii)  The Conversion Price shall not be greater than the Conversion
               Cap. The Conversion Cap shall be calculated as follows: the mean
               between the closing bid price and closing ask price

                                      -5-
<PAGE>
 
               (as reported on NASDAQ) for each trading day during the 90-day
               period following the Closing Date (not including the Closing
               Date) shall be averaged; the Conversion Cap shall be equal to
               115% of the resulting average.

          iii) The "lowest trade price" of the Common Stock on any day shall be
               the lowest reported sale price of the Common Stock on NASDAQ or
               any other principal securities price quotation system or market
               on which prices of the Common Stock are reported. The term
               "trading day" means a day on which trading is reported on the
               principal quotation system or market on which prices of the
               Common Stock are reported.

          iv)  If during any period of consecutive trading days provided for
               above, the Corporation shall declare or pay any dividend on the
               Common Stock payable in Common Stock or in rights to acquire
               Common Stock, or shall effect a stock split or reverse stock
               split, or a combination, consolidation or reclassification of the
               Common Stock, then the Conversion Price shall be proportionately
               decreased or increased, as appropriate, to give effect to such
               event. If any such event occurs after the Conversion Cap has been
               determined, the Conversion Cap shall be proportionately decreased
               or increased, as appropriate, to give effect to such event.

     d)   Distributions. If the Corporation shall at any time or from time to
          --------------
          time make or issue, or fix a record date for the determination of
          holders of Common Stock entitled to receive, a dividend or other
          distribution payable in securities of the Corporation or any of its
          subsidiaries other than additional shares of Common Stock, then in
          each such event provision shall be made so that the holders of 5%
          Preferred shall receive, upon the conversion thereof, the securities
          of the Corporation which they would have received had they been the
          owners on the date of such event of the number of shares of Common
          Stock issuable to them upon conversion.

     e)   Certificates as to Adjustments. Upon the occurrence of any adjustment
          -------------------------------
          or readjustment of the Conversion Price or the Conversion Cap pursuant
          to this Section 4, the Corporation at its expense shall promptly
          compute such 

                                      -6-
<PAGE>
 
          adjustment or readjustment in accordance with the terms hereof and
          cause the independent public accountants regularly employed to audit
          the financial statements of the Corporation to verify such computation
          and prepare and furnish to each holder of 5% Preferred a certificate
          setting forth such adjustment or readjustment and showing in detail
          the facts upon which such adjustment or readjustment is based. The
          Corporation shall, upon the written request at any time of any holder
          of 5% Preferred, furnish or cause to be furnished to such holder a
          like certificate prepared by the Corporation setting forth (i) such
          adjustments and readjustments, and (ii) the number of other securities
          and the amount, if any, of other property which at the time would be
          received upon the conversion of 5% Preferred with respect to each
          shares of Common Stock received upon such conversion.

     f)   Notice of Record Date. In the event of any taking by the Corporation
          ----------------------
          of a record of the holders of any class of securities for the purpose
          of determining the holders thereof who are entitled to receive any
          dividend (other than a cash dividend) or other distribution, any
          security or right convertible into or entitling the holder thereof to
          receive additional shares of Common Stock, or any right to subscribe
          for, purchase or otherwise acquire any shares of stock of any class or
          any other securities or property, or to receive any other right, the
          Corporation shall mail to each holder of 5% Preferred at least 10 days
          prior to the date specified therein, a notice specifying the date on
          which any such record is to be taken for the purpose of such dividend,
          distribution, security or right and the amount and character of such
          dividend, distribution, security or right.

     g)   Issue Taxes. The Corporation shall pay any and all issue and other
          ------------
          taxes, excluding any income, franchise or similar taxes, that may be
          payable in respect of any issue or delivery of shares of Common Stock
          on conversion of shares of 5% Preferred pursuant hereto; provided,
          however, that the Corporation shall not be obligated to pay any
          transfer taxes resulting from any transfer requested by any holder in
          connection with any such conversion.

     h)   Reservation of Stock Issuable Upon Conversion. The Corporation shall
          ----------------------------------------------
          at all times reserve and keep available out of its authorized but
          unissued shares of Common 

                                      -7-
<PAGE>
 
          Stock, solely for the purpose of effecting the conversion of the
          shares of the 5% Preferred, such number of its shares of Common Stock
          as shall from time to time be sufficient to effect the conversion of
          all outstanding shares of the 5% Preferred, subject to the limitation
          set forth in subsection (l) below, and if at any time the number of
          authorized but unissued shares of Common stock shall not be sufficient
          to effect the conversion of all then outstanding shares of the 5%
          Preferred, the Corporation will take such corporate action as may, in
          the opinion of its counsel, be necessary to increase its authorized
          but unissued shares of Common Stock to such number of shares as shall
          be sufficient for such purpose, including, without limitation,
          engaging in best efforts to obtain the requisite shareholder approval.

     i)   Fractional Shares.  No fractional shares shall be issued upon the
          ------------------                                               
          conversion of any share or shares of 5% Preferred. All shares of
          Common Stock (including fractions thereof) issuable upon conversion of
          more than one share of 5% Preferred by a holder thereof shall be
          aggregated for purposes of determining whether the conversion would
          result in the issuance of any fractional share. If, after the
          aforementioned aggregation, the conversion would result in the
          issuance of a fraction of a share of Common Stock, the Corporation
          shall, in lieu of issuing any fractional share, pay the holder
          otherwise entitled to such fraction a sum in cash equal to the fair
          market value of such fraction on the date of conversion (as determined
          in good faith by the Board of Directors of the Corporation).

     j)   Notices.  Any notice required by the provisions of this Section to be
          --------                                                             
          given to the holders of shares of 5% Preferred shall be deemed given
          if deposited in the United States mail, postage prepaid, and addressed
          to each holder of record at its address appearing on the books of the
          Corporation.

     k)   Reorganization or Merger.  In case of any reorganization or any
          -------------------------                                      
          reclassification of the capital stock of the Corporation or any
          consolidation or merger of the Corporation with or into any other
          corporation or corporations or a sale of all or substantially all of
          the assets of the Corporation to any other person, and the holders of
          5% Preferred do not elect to treat such transaction as a liquidation,
          dissolution or winding up as provided in Section 2, then, as part of
          such 

                                      -8-
<PAGE>
 
          reorganization, consolidation, merger or sale, provision shall be
          made so that each share of 5% Preferred shall thereafter be
          convertible into the number of shares of stock or other securities or
          property (including cash) to which a holder of the number of shares of
          Common Stock deliverable upon conversion of such share of 5% Preferred
          would have been entitled upon the record date of (or date of, if no
          record date is fixed) such event and, in any case, appropriate
          adjustment (as determined by the Board of Directors) shall be made in
          the application of the provisions herein set forth with respect to the
          rights and interests thereafter of the holders of the 5% Preferred, to
          the end that the provisions set forth herein shall thereafter be
          applicable, as nearly as equivalent as is practicable, in relation to
          any shares of stock or the securities or property (including cash)
          thereafter deliverable upon the conversion of the shares of 5%
          Preferred.

     l)   Limitation on Number of Conversion Shares.  The Corporation shall not
          ------------------------------------------                           
          be obligated to issue, in the aggregate, more than 3,717,529 shares of
          Common Stock as presently constituted (the "NASDAQ Cap") upon (1)
          conversion of the 5% Preferred, (2) exercise of the warrants issued to
          Cappello & Laffer Capital Corp. or its designees in connection with
          the sale of the 5% Preferred and the sale of stock to entities advised
          by Dimensional Fund Advisors, and (3) the issuance of 600,000 shares
          on or about July 17, 1996 to entities advised by Dimensional Fund
          Advisors, if issuance of a larger number of shares would constitute a
          breach of the Corporation's obligations under its agreements with the
          NASD or NASDAQ or the rules of such organizations. Subject to the
          obligation to effect certain redemptions pursuant to the last three
          sentences of this subsection (l), if further issuances of shares of
          Common Stock pursuant to clauses (1) through (3) would constitute a
          breach of the Corporation's obligations under any applicable
          agreements with the NASD or NASDAQ or the rules of such organizations
          (i.e., all of the shares permitted to be issued under the NASDAQ Cap
          shall have been so issued), then so long thereafter as such limitation
          shall continue to be applicable and any shares of 5% Preferred are
          submitted for conversion, if such submision is prior to 136 days after
          the Closing Date, such shares shall receive in cash an amount equal to
          111.11% of the Liquidation Preference of such shares, or if such
          submission is subsequent to 135 days after the Closing

                                      -9-
<PAGE>
 
          Date, such shares shall receive in cash an amount equal to the the
          greater of (i) 111.11% of the Liquidation Preference of such shares or
          (ii) the current value of the Common Stock which such shares would
          otherwise be entitled to receive upon conversion (such value per share
          to be the closing price of such shares as reported by NASDAQ on the
          Conversion Date), in lieu of the Common Stock which such shares would
          otherwise be entitled to receive upon conversion, and such shares will
          be deemed cancelled. Payment of said cash amount shall be made no
          later than one business day after the time specified in Section 4(b)
          for the delivery o Common Stock upon conversion, and shall bear daily
          interest thereafter at the rate of one-tenth of one percent per day
          until paid. Such maximum number of shares of Common Stock shall be
          proportionately and equitably adjusted in the event of stock splits,
          stock dividends, reverse stock splits, reclassifications or other such
          events, in such manner as the Board of Directors of the Corporation
          shall reasonably determine. If the Corporation is unable to obtain the
          requisite shareholder approval concerning the issuance of shares of
          Common Stock in connection with the events specified in clauses (1)
          through (3) above to satisfy all NASD and NASDAQ requirements prior to
          120 days after the date of issuance, the Corporation shall then
          redeem, at a "Special Redemption Price" equal to 111.11% of the
          Liquidation Preference of such shares, a number of shares equal to
          $75,000,000 (plus any earnings accumulated thereon from the Closing
          Date until the Redemption Date) divided by the Special Redemption
          Price. Any redemption effected pursuant to the preceding sentence
          shall require no more than 10 days' notice and the Redemption Date
          shall be not more than 135 days after the date of issuance. Such
          redemption shall be made pro rata based on the number of shares of the
          5% Preferred outstanding at 11:59 p.m. on the day prior to the
          Redemption Date, and as early as practicable on the Redemption Date
          the Corporation shall notify each holder of 5% Preferred by the most
          rapid means of communication available to the Corporation, which may
          be facsimilie transmission, of the pro rata number of shares to be
          redeemed from each holder. Such notice shall be binding upon holders
          who have submitted their stock certificates for redemption prior to
          the receipt of such notice, as well as on holders who submit their
          stock certificates thereafter. If there shall be a default in payment
          of the Special Redemption Price, the amount so payable shall bear
          daily interest from and after the Redemption Date at

                                      -10-
<PAGE>
 
          the rate of one-tenth of one percent per day until paid. Shares so
          redeemed shall be deemed to have been redeemed at the opening of
          business on the Redemption Date and shall no longer be treated as
          outstanding shares except for purposes of receiving the Special
          Redemption Price.

     m)   Reissuance of Certificates.  In the event of an optional conversion of
          ---------------------------                                           
          5% Preferred pursuant to Section 4(a) hereof or a redemption of 5%
          Preferred pursuant to Section 4(1) hereof in which less than all of
          the shares of 5% Preferred of a particular certificate are converted
          or redeemed, as the case may be, the Corporation shall promptly cause
          to be issued and delivered to the holder of such certificate, a
          certificate representing the remaining shares of 5% Preferred which
          have not been so converted or redeemed.

5.   Other Provisions.  For all purposes of this Resolution, the term "date of
     -----------------                                                        
     issuance" and the terms "Closing" or "Closing Date" shall mean the day on
     which shares of the 5% Preferred are first issued by the Corporation.  Any
     provision herein which conflicts with or violates any applicable usury law
     shall be deemed modified to the extent necessary to avoid such conflict or
     violation.  The term "NASDAQ" herein refers to the principal market on
     which the Common Stock of the Company is traded.  If the Common Stock is
     listed on a securities exchange, or if another market becomes the
     principal market on which the Common Stock is traded or through which price
     quotations for the Common Stock are reported, the term "NASDAQ" shall be
     deemed to refer to such exchange or other principal market.

     to amend or change any of the rights, preferences or privileges of the 5%
     Preferred, (ii) authorize or issue any other preferred equity security
     senior to or on a parity with the 5% Preferred, as to dividends,
     liquidation, preferences, conversion rights, redemption rights or other
     rights, preferences or privileges, or (iii) purchase or otherwise acquire
     for value any Common Stock or other equity security of the Corporation
     either junior or senior to or on a parity with the 5% Preferred while there
     exists any arrearage in the payment of cumulative dividends hereunder.

     by such holder in connection with enforcement by such holder of any
     obligation of the Corporation hereunder.

     limitation, any Certificate of Designation), merger, reorganization,
     recapitalization, consolidation, sales of assets, sale of stock, tender
     offer, dissolution or otherwise, take any action, or permit any action to
     be taken, solely or primarily for the purpose of increasing the value of
     any class of stock of the Corporation if the effect of such action is to
     reduce the value or security of the Preferred Stock.

10.  Limits on Conversion of 5% Preferred Stock.  Notwithstanding any right of
     -------------------------------------------                              
     conversion of 5% Preferred Stock provided for above, no such shares of 5%
     Preferred Stock originally issued by the Corporation to a bank holding
     company or an affiliate of a bank holding company shall be converted into
     shares of Common Stock or any other class or series of voting stock by the
     original holder or any direct or indirect transferee thereof such that
     immediately after such conversion such person and its affiliates (which
     term, for avoidance of doubt, includes such bank holding company, any such
     transferee and their respective affiliates) would own  more than 4.9% of
     any class of voting securities of the Corporation, unless such shares are
     being distributed, disposed of or sold in any one of the following
     transactions (each a "Conversion Event"):

     a)  an initial public offering or other widely-dispersed public
         distribution of the shares of the Company;

          of the Company's voting stock held by persons other than the bank
          holding company investor;

     d)  a private sale of such equity so long as no purchaser acquires more
         than 2% of the total equity outstanding 

                                      -12-

         upon conversion; or

     e)  such shares are being sold in any other manner permitted by the
         Federal Reserve Board.

     For purposes of this Section 10, "persons" shall include any natural person
                                       -------                                  
     and any corporation, partnership, joint venture, trust, unincorporated
     organization and any other entity or organization and percentages of the
     Corporation's outstanding voting securities shall include shares issuable
     upon exercise or conversion of 5% Preferred Stock and other convertible
     securities, options, warrants or other similar instruments owned by such
     bank holding company, its transferees and their respective affiliates, but
     shall not include shares issuable upon exercise or conversion of
     convertible securities, options, warrants or other similar instruments
     owned by any other person.  The provisions of this Section 10 shall not
     limit or affect the right of the Corporation to force conversion pursuant
     to Section 3(a) hereof nor the automatic conversion provided for in Section
     3(d) hereof.  The Corporation shall have no obligation to monitor
     compliance with the limits set forth in this Section 10 or the holdings of
     any shareholder, and shall have no liability for the failure of any person
     to comply with such limits.

3.  The Amended and Restated Certificate of Incorporation is amended so that the
relative rights, preferences and limitations of the 5% Preferred are as stated
in the resolution set forth in Paragraph 2 above.

     IN WITNESS WHEREOF, Roberts Pharmaceutical Corporation has caused its duly
authorized officer to execute this Certificate of Amendment on August 26, 1996.

                            CERTIFICATE OF AMENDMENT

14A:7-18(2) of the New Jersey Business Corporation Act, the undersigned
corporation executes the following Certificate of Amendment to its Amended and
Restated Certificate of Incorporation:


1.   The name of the corporation is "Roberts Pharmaceutical Corporation".

2.   By resolution adopted December 19, 1990, the Corporation's Board of
     Directors approved the cancellation of 2,000,000 shares of Class A
     Preferred Stock, $.10 par value (the "Class A Shares"), which were
     reacquired by the Corporation.  In accordance with Section 4.02(C)(7) of
     the Corporation's Amended and Restated Certificate of Incorporation, upon
     the reacquisition of the Class A Shares, the Class A Shares ceased to be
     authorized shares of the Corporation.

3.   After giving effect to the cancellation of the Class A Shares, the number
     of shares of stock which the Corporation was authorized to issue was:
     50,000,000 shares of Common Stock, $.01 par value per share, and 10,000,000
     shares of Class B Preferred Stock, $.10 par value per share.

4.   The Corporation's Amended and Restated Certificate of Incorporation
     provides that the Class A Shares shall not be reissued.

5.   The Corporation's Amended and Restated Certificate of Incorporation is
     amended by decreasing the aggregate number of Class A Shares which the
     Corporation is authorized to issue by the 2,000,000 Class A Shares
     cancelled by the Corporation.

6.   The following amendment to the Amended and Restated Certificate of
     Incorporation (the "Amendment") was approved by the directors and
     thereafter duly adopted by the shareholders of the Corporation on the 6th
     day of November 1996:

     Section 4.01 of Article Four of the Amended and Restated Certificate of
     Incorporation is amended to read in its entirety as follows:
<PAGE>
 
          "The total number of shares of stock which the Corporation shall have
          authority to issue is One Hundred and Ten Million (110,000,000)
          shares.  Of these shares, One Hundred Million (100,000,000) shares are
          classified as Common Stock, par value $.01 per share, and Ten Million
          (10,000,000) shares are classified as Class B Preferred Stock, par
          value $.10 per share."


7.   The total number of shares entitled to vote on the adoption of the
     Amendment was 19,207,402 shares of Common Stock, $.01 par value per share
     (the "Common Stock").

8.   The number of shares of Common Stock voted in favor of the Amendment was
     18,057,336 shares.  There were 863,532 shares of Common Stock voted against
     the Amendment, and 140,006 shares of Common Stock abstained from voting on
     the Amendment.

particular country; however, upon such election any rights that Roberts has in

the date of mailing. In the event such an election is made, Lilly's obligations

terminate thirty (30) days from the date of mailing with respect to the specific
patent on which the election is made.

a course of action, including, but not limited to, the commencement of legal
action by one or both parties, to cause such infringement, potential
infringement or suspected infringement to be terminated.  Each party, at its

infringement becomes known to both parties, either party shall have the right,
at its own expense, to initiate and prosecute an action against the infringer
and shall retain whatever damages are recovered.  In the event Roberts is unable
to initiate and prosecute such action solely in its own name, Lilly will execute
(and cause its Affiliates to execute) all documents necessary for Roberts to

settlement of any action referred to in this Section without the other party's
prior consent, which consent shall not be unreasonably withheld.

proceeding, the parties shall consult as to the desirability or necessity of
such a proceeding.   Such proceedings will not be abandoned prior to a final
decision of the Patent Office Board of Appeals or Patent Office Board of
Interferences and the applicable foreign equivalent without the consent of
Roberts, which consent will not be unreasonably withheld taking into
consideration, inter alia, the merits of the action of the Patent and Trademark
Office and the applicable foreign equivalent, priority dates provable by any
interference party (should an interference be involved), and the technological
and commercial importance of the subject matter of the claims of the application
or patent involved expenses shall be borne as provided in Section 4.03.

                               LICENSE AGREEMENT
                                   [LY246736]

     This License Agreement ("Agreement") is made as of the 5th day of November,
1996 by and between Eli Lilly and Company, an Indiana corporation ("Lilly") and
Roberts Laboratories Inc., a New Jersey corporation ("Roberts").

     1.   Lilly and Roberts are in the business of discovering, developing and
marketing pharmaceutical products.

     2.   Lilly  has discovered a compound internally designated as LY246736 (as
defined in Section 1.02 below, the "Compound") which may be useful in the
treatment of functional gastrointestinal disorders and other indications.  Lilly
has previously engaged in certain research and development efforts with respect
to the Compound, but has concluded that future development efforts could best be
conducted by a company with a focus on gastrointestinal products.

     3.   Roberts desires to license from Lilly certain rights of Lilly to the
Compound and to pursue development and commercialization of the Compound within
the Territory (as defined below), and Lilly is willing to grant such license,
all upon the terms and conditions set forth in this License Agreement.

                                   AGREEMENT

                                     -4-
 
Property Rights licensed to Roberts hereunder. Roberts will provide Lilly with
all material and information as may be necessary to obtain any of the aforesaid
rights.

     Section 4.02.  Prosecution and Maintenance of Licensed Patents.
     -------------------------------------------------------------- 

     (a) Appendix B attached hereto identifies all pending applications and
     patents worldwide which are encompassed in the Lilly Intellectual Property
     Rights.

     (b) Lilly shall prosecute any pending applications of which it is the owner
     that are encompassed in the Lilly Intellectual Property Rights and maintain
     any patents that have issued or will issue thereon in full force and effect
     for the term of such patent.  Should, during the course of prosecution of
     any pending claims, an official action rejecting the claims require that an
     amendment be made or action be taken which would limit or substantially
     change the scope of any license hereunder, Lilly will timely inform Roberts
     in writing.  Lilly shall consult Roberts before responding to any such
     official action, and allow Roberts to assist in the prosecution of such
     claims or, at Lilly's option, allow Roberts the opportunity at its time and
     expense to prosecute such claims to Roberts satisfaction.

     Section 4.03.  Costs of Prosecution and Maintenance of Patents.  Lilly
     --------------------------------------------------------------        
shall bear all costs incurred in filing, prosecuting and maintaining all patents
and patent applications encompassed within the Intellectual Property Rights,
provided, however, that Roberts shall pay one-half (1/2) of all reasonable
external expenses incurred by Lilly while prosecuting and maintaining such
patents and patent applications.  External expenses will include patent office
fees and taxes in connection with the prosecution and maintenance of any patent
or patent application and the fees of any patent attorneys or agents, external
of Lilly, in connection with the ex parte prosection and maintenance thereof.
                                 -- -----                                     
The allocation of such expenses will occur on a annual basis at the end of the
last quarter of each calendar year, at which time Lilly will provide Roberts
with an itemized list of external expenses denominated in United States dollars
incurred during the previous annual period.  Roberts will then reimburse Lilly's
expenses within sixty (60) days of the date of receipt of this itemized list.
Notwithstanding the foregoing, Lilly may, at its sole discretion, choose not to
prosecute or cease to maintain a patent or patent application in any country as
it so desires and to the extent that Lilly chooses not to prosecute or ceases to
maintain such patent or patent application Lilly shall not be responsible for
any patent costs associated with prosecuting and/or maintaining the patent or
patent application in such country.  If Roberts desires to prosecute or maintain
such patent or patent application Roberts may do so at its own expense; however,
under these circumstances,  Lilly would grant Roberts all of its patent rights
associated with such patent in such country.  Similarly, upon written notice to
Lilly, Roberts may elect not to share in the prosecution or maintenance costs as
described in this Section 4.03 related to a patent or patent application in a
particular country; however, upon such election any rights that Roberts has in
such patent in such country would be granted to Lilly.

     Section 4.04.  Option by Roberts to Discontinue License.  Roberts, at its
     -------------------------------------------------------                  
option, may elect to discontinue the license granted and surrender all rights
hereunder as to any patent on a country-by-country basis.  Such election must be
made by thirty (30) days written notice by simultaneous facsimile transmission
and certified mailing, and, with respect to the surrender of Roberts' rights,
will be effective as of the date of mailing.  In the event such an election is
made, Lilly's obligations under Sections 4.01 and 4.02 and Roberts' obligations
under Section 4.03 will terminate thirty (30) days from the date of mailing with
respect to the specific patent on which the election is made.

     Section 4.05.  Infringement.  Each party shall give prompt notice to the
     ---------------------------                                             
other of any infringement, potential infringement or suspected infringement of
Lilly Intellectual Property Rights that may come to such party's attention.
Promptly thereafter, the parties shall consult and cooperate fully to determine
a course of action, including, but not limited to, the commencement of legal
action by one or both parties, to cause such infringement, potential
infringement or suspected infringement to be terminated.  Each party, at its
option, may elect to participate in or commence such a legal action.  In the
event of a joint action in which both parties agree to participate, the parties
will share in the costs and the recovery of the agreed upon course of action in
a manner to be agreed upon.  Failing agreement on a course of action to abate
infringement, potential infringement or suspected infringement within sixty (60)
days of the time of such infringement, potential infringement or suspected
infringement becomes known to both parties, either party shall have the right,
at its own expense, to initiate and prosecute an action against the infringer
and shall retain whatever damages are recovered.  In the event Roberts is unable
to initiate and prosecute such action solely in its own name, Lilly will execute
(and cause its Affiliates to execute) all documents necessary for Roberts to
initiate and prosecute such action.  Neither party will enter into any
settlement of any action referred to in this Section without the other party's
prior consent, which consent shall not be unreasonably withheld.

     Section 4.06.  Reexamination and Reissue.  Lilly shall defend in a
     ----------------------------------------                          
reasonable manner any patent encompassed within the Lilly Intellectual Property
Rights in any reexamination or reissue proceeding in the United States Patent
and Trademark Office and the applicable foreign equivalent.  Before Lilly
initiates a reissue proceeding, or before either party initiates a reexamination
proceeding, the parties shall consult as to the desirability or necessity of
such a proceeding.  Such proceedings will not be abandoned prior to a final
decision of the Patent Office Board of Appeals or Patent Office Board of
Interferences and the applicable foreign equivalent without the consent of
Roberts, which consent will not be unreasonably withheld taking into
consideration, inter alia, the merits of the action of the Patent and Trademark
Office and the applicable foreign equivalent, priority dates provable by any
interference party (should an interference be involved), and the technological
and commercial importance of the subject matter of the claims of the application
or patent involved expenses shall be borne as provided in Section 4.03.

Roberts nor Lilly shall release any information to any third party with respect
to the existence and terms of this Agreement without the prior written consent
of the other party to this Agreement.

     This prohibition includes, but is not limited to, press releases,
educational and scientific conferences, promotional materials, governmental
filings, and discussions with lenders, investment bankers, public officials, and
the media.

     Section 5.02.  Releases Required by Law.  If either party determines a
     ---------------------------------------                               
release of information is required by law or governmental regulation, it shall
notify the other in writing at least ten (10) days (or such shorter period where
legally required) before the time of the proposed release.  The notice shall
include the exact text of the proposed release, the time and manner of the
release, and the basis for such party's belief that disclosure is required.

     At the other party's request and before the release, the party desiring to
release information shall consult with the other party on the necessity for the
disclosure and the text of the proposed release.  In no event shall a release
include information regarding the existence or terms of this Agreement that is
not required by law or governmental regulation without the consent of the other
party.

     Notwithstanding any other terms of this Agreement, either party shall be
permitted and allowed to provide a copy of this Agreement or any terms hereof or
otherwise provide any information with respect to the existence and terms of
this Agreement to appropriate governmental taxing or drug regulatory authorities
requested, without advance written notice or approval of the other party.

     -----------------------------                                        
efforts to develop and commercialize Products throughout the Territory.  Roberts
may abandon development efforts for the Compound at any time if in the
reasonable judgment of Roberts further development efforts are not justified.
If Roberts so abandons development, it shall upon request assign to Lilly or
Lilly's designee all intellectual property, records, data, clinical trial
results and other information relating to the Compound in return for which Lilly
or its 
<PAGE>
                                     -7-
 
designee shall pay to Roberts an amount equal to Roberts' total development
costs (including all out of pocket costs and reasonable internal costs). Roberts
shall comply with all responsibilities for all adverse event reporting, annual
reporting and any other reporting responsibilities to regulatory agencies in the
Territory.

     Section 6.03.  Technical Assistance.  For a period of one hundred eighty

personnel, provide Roberts with such technical assistance, information and
advice regarding the use of Lilly Intellectual Property Rights and the Know-How
that may be reasonably necessary in connection with the manufacturing and
testing of the Compound and Product.  Lilly, at its expense, also agrees that
such assistance may include one (1) visit to the Roberts facilities (not to
exceed twenty-four (24) hours) located in New Jersey by at least one (1)
qualified member of Lilly's personnel to render on-site technical assistance.
Except for the on-site visit described in this Section 6.03, all costs external

Roberts.  Furthermore, Lilly shall not be required to engage extra personnel or
to provide facilities in connection with providing technical assistance.

     Section 7.01.  Sales and Royalty Reports.  Roberts shall deliver to Lilly

year.  All sales and royalty reports shall be directed to Eli Lilly and Company,
Attn:  Royalty Administration, D.C. 2211, Lilly Corporate Center, Indianapolis,
Indiana  46285.  In the event Roberts makes Sales of Product(s) to persons other
than End Users, Roberts shall require such persons to provide Roberts with such
information as Lilly may reasonably request to permit Lilly to calculate and
verify Net Sales and Royalties due.

     Section 7.02.  Delivery of Royalty.  When Roberts delivers the accounting
     ----------------------------------                                       
to Lilly, Roberts shall also pay by wire transfer or other method acceptable to
Lilly royalty payments due to Lilly for the preceding calendar quarter.  Any
payment not made when due shall bear interest at the United States prime rate on
due date as published in the Wall Street Journal, plus six percent (6%).
                             -------------------                        

     Section 7.03.  Audits.  Roberts shall keep accurate records in sufficient
     ---------------------                                                    
detail to enable to amounts due to Lilly hereunder to be determined.  During the
term of this Agreement and for two (2) years after its termination, Lilly shall,
not more than once each year and upon written notice, have the right, at its
expense, to audit the books and records of 
<PAGE>
                                     -8-
 
Roberts for the purpose of determining the accuracy of royalty payments. If
Roberts has underpaid a royalty amount due under this Agreement by more than
five percent (5%), Roberts shall, in addition to paying any royalties due, also
reimburse Lilly for the cost of such audit.

     Section 7.04.  Exchange Rates and Currency Translation.  All payments to be
     ------------------------------------------------------                     
made by Roberts to Lilly under this Agreement shall be made and reported in
United States dollars.  The rate of exchange to be used in computing the amount
of Net Sales and the United States dollars due Lilly shall be calculated using
Roberts' then current standard exchange rate methodology, which methodology is
used by Roberts in the translation of its foreign currency operating results for
external reporting, is consistent with United States generally accepted
accounting principles and generally reviewed and approved by Roberts'
independent certified public accountants.

     Section 7.05.  Withholding Taxes.  Roberts shall have no liability for any
     --------------------------------                                          
income taxes levied against Lilly on account of royalties paid hereunder.  If
laws or regulations require that any such taxes be withheld by Roberts, Roberts
shall deduct such taxes from the payment due Lilly, pay the taxes to withheld to
the proper taxing authority, and send proof of payment to Lilly annually within
ninety (90) days of the first day of the year following such payment.  If Lilly
desires to obtain a refund of any taxes so withheld and paid to a taxing
authority, Roberts shall cooperate in the pursuit of such refund.

the last to expire of the patents encompassed in the  Lilly Intellectual

any of its material obligations under this Agreement, or fails to remedy such a
default within sixty (60) days after the other party sends written notice
detailing the substance of the default to the defaulting party, the injured
party may terminate this Agreement by written notice.  In the event Lilly elects
to terminate this Agreement by reason of any default by Roberts, the licenses
granted hereunder shall terminate.

     Section 8.03.  Residual Obligation Upon Termination.  Termination of this

                                   [LY353433]

     This License Agreement ("Agreement") is made as of the 5th day of November,
1996 by and between Eli Lilly and Company, an Indiana corporation ("Lily") and

marketing pharmaceutical products.

     2.   Lilly has discovered a compound internally designated as LY353433 (as
defined in Section 1.02 below, the "Compound") which may be useful in the
treatment of functional gastrointestinal disorders and other indications.  Lilly
has previously engaged in certain research and development efforts including
limited clinical trials with respect to the Compound, but has concluded that
future development efforts could best be conducted by a company with a focus on
gastrointestinal products.

     3.   Roberts desires to license from Lilly certain rights of Lilly to the
Compound and to pursue development and commercialization of the Compound within
the Territory (as defined below), and Lilly is willing to grant such license,
all upon the terms and conditions set forth in this License Agreement.

                                   AGREEMENT

         force and effect for the term of such patent. Should, during the course
         of prosecution of any pending claims, an official action rejecting the
         claims require that an amendment be made or action be taken which would
         limit or substantially change the scope of any license hereunder, Lilly
         will timely inform Roberts in writing. Lilly shall consult Roberts
         before responding to any such official action, and allow Roberts to
         assist in the prosecution of such claims or, at Lilly's option, allow
         Roberts the opportunity at its time and expense to prosecute such
         claims to Roberts satisfaction.

     Section 4.03.  Costs of Prosecution and Maintenance of Patents.  Lilly
     --------------------------------------------------------------        
shall bear all costs incurred in filing, prosecuting and maintaining all patents
and patent applications encompassed within the Intellectual Property Rights,
provided, however, that Roberts shall pay one-half (1/2) of all reasonable
external expenses incurred by Lilly while prosecuting and maintaining such
patents and patent applications.  External expenses will include patent office
fees and taxes in connection with the prosecution and maintenance of any patent
or patent application and the fees of any patent attorneys or agents, external
of Lilly, in connection with the ex parte prosecution and maintenance thereof.
                                 -- -----                                      
The allocation of such expenses will occur on an annual basis at the end of the
last quarter of each calendar year, at which time Lilly will provide Roberts
with an itemized list of external expenses denominated in United States dollars
incurred during the previous annual period.  Roberts will then reimburse Lilly's
expenses within sixty (60) days of the date of receipt of this itemized list.
Notwithstanding the foregoing, Lilly may, at its sole discretion, choose not to
prosecute or cease to maintain a patent or patent application in any country as
it so desires and to the extent that Lilly chooses not to prosecute or ceases to
maintain such patent or patent application Lilly shall not be responsible for
any patent costs associated with prosecuting and/or maintaining the patent or
patent application in such country.  If Roberts desires to prosecute or maintain
such patent or patent application Roberts may do so at its own expense; however,
under these circumstances, Lilly would grant Roberts all of its patent rights
associated with such patent in such country.  Similarly, upon written notice to
Lilly, Roberts may elect not to share in the prosecution or maintenance costs as
described in this Section 4.03 related to a patent or patent application in a
particular country; however, upon such election any rights that Roberts has in
such patent in such country would be granted to Lilly.

     Section 4.04.  Option by Roberts to Discontinue License.  Roberts, at its
     -------------------------------------------------------                  
option, may elect to discontinue the license granted and surrender all rights
hereunder as to any patent on a country-by-country basis.  Such election must be
made by thirty (30) days written notice by simultaneous facsimile transmission
and certified mailing, and, with respect to the surrender of Roberts' rights,
will be effective as of the date of mailing.  In the event such an election is
made, Lilly's obligations under Section 4.01 and 4.02 and Roberts' obligations
under Section 4.03 will terminate thirty (30) days from the date of mailing with
respect to the specific patent on which the election is made.

     Section 4.05.  Infringement.  Each party shall give prompt notice to the
     ---------------------------                                             
other of any infringement, potential infringement or suspected infringement of
Lilly Intellectual Property Rights that may come to such party's attention.
Promptly thereafter, the parties shall consult and cooperate fully to determine
a course of action, including, but not limited to, the commencement of legal
action by one or both parties, to cause such infringement, potential
infringement, or suspected infringement to be terminated.  Each party, at its
option, may elect to participate in or commence such a legal action.  In the
event of a joint action in which both parties agree to participate, the parties
will share in the costs and the recovery of the agreed upon course of action in
a manner to be agreed upon.  Failing agreement on a course of action to abate
infringement, potential infringement or suspected infringement within sixty (60)
days of the time such infringement, potential infringement or suspected
infringement becomes known to both parties, either party shall have the right,
at its own expense, to initiate and prosecute an action against the infringer
and shall retain whatever damages are recovered.  In the event Roberts is unable
to initiate and prosecute such action solely in its own name, Lilly will execute
(and cause its Affiliates to execute) all documents necessary for Roberts to
initiate and prosecute such action.  Neither party will enter into any
settlement of any action referred to in this Section without the other party's
prior consent, which consent shall not be unreasonably withheld.

     Section 4.06.  Reexamination and Reissue.  Lilly shall defend in a
     ----------------------------------------                          
reasonable manner any patent encompassed within the Lilly Intellectual Property
Rights in any reexamination or reissue proceeding in the United States Patent
and Trademark Office and the applicable foreign equivalent.  Before Lilly
initiates a reissue proceeding, or before either party initiates a reexamination
proceeding, the parties shall consult as to the desirability or necessity of
such a proceeding.  Such proceedings will not be abandoned prior to a final
decision of the Patent Office Board of Appeals or Patent Office Board of
Interferences and the applicable foreign equivalent without the consent of
Roberts, which consent will not be unreasonably withheld taking into
consideration, inter alia, the merits of the action of the Patent and Trademark
Office and the applicable foreign equivalent, priority dates provable by any
interference party (should an interference be involved), and the technological
and commercial importance of the subject matter of the claims of the application
or patent involved expenses shall be borne as provided in Section 4.03.

release of information is required by law or governmental regulation, it shall
notify the other in writing at least ten (10) days (or such shorter period where

                              CERTAIN UNDERTAKINGS
                              --------------------

     Section 6.01.  Lilly Warranties.  Lilly hereby warrants that it, to the
     -------------------------------                                        
best of its knowledge, is the sole owner of or is duly licensed under the Lilly
Intellectual Property Rights licensed to Roberts hereunder and has a lawful
right to grant the rights and licenses granted to Roberts hereunder.

     Section 6.02.  Roberts Efforts.  Roberts hereby agrees to use its best
     ------------------------------                                        
efforts to develop and commercialize Products throughout the Territory.  Roberts
may abandon development efforts for the Compound at any time if in the
reasonable judgment of Roberts further development efforts are not justified.
If Roberts so abandons development, it shall upon request assign to Lilly or
Lilly's designee all intellectual property, records, data, clinical trial
results and other information relating to the Compound in return for which Lilly
or its designee shall pay to Roberts an amount equal to Roberts' total
development costs (including all out of pocket costs and reasonable internal
costs).  Furthermore, upon execution of this Agreement, Roberts shall comply
with all responsibilities for all adverse 
<PAGE>
 
                                     -7-
 
event reporting, annual reporting and any other reporting responsibilities to
regulatory agencies in the Territory.

     Section 6.03.  Technical Assistance.  For a period of one hundred eighty
     -----------------------------------                                     
(180) days from the date hereof, Lilly will, through certain designated
personnel, provide Roberts with such technical assistance, information and
advice regarding the use of Lilly Intellectual Property Rights and the Know-How
that may be reasonably necessary in connection with the manufacturing and
testing of the Compound and Product.  Lilly, at its expense, also agrees that
such assistance may include one (1) visit to the Roberts facilities (not to
exceed twenty-four (24) hours) located in New Jersey by at least one (1)
qualified member of Lilly's personnel to render on-site technical assistance.
Except for the on-site visit described in this Section 6.03, all costs external
to Lilly and associated with technical assistance shall be borne entirely by
Roberts.  Furthermore, Lilly shall not be required to engage extra personnel or
to provide facilities in connection with providing technical assistance.

                                  ARTICLE VII
                                  -----------
                                   ACCOUNTING
                                   ----------

     Section 7.01. Sales and Royalty Reports.  Roberts shall deliver to Lilly
     ---------------------------------------                                 
within sixty (60) days after the end of each calendar quarter a written
accounting of Roberts' Net Sales and the royalty payment due to Lilly for such
quarter.  Such quarterly reports shall be in English and include the Net Sales
of products on a country-by-country basis (expressed in United States dollars or
computed under the provisions of Section 7.04 hereof), a sales forecast for each
quarter of the current calendar year, and contain such other information as
Lilly may from time to time reasonably request.  Annually, by October 1, Roberts
shall deliver to Lilly a sales forecast, by quarter, for the subsequent calendar
year.  All sales and royalty reports shall be directed to Eli Lilly and Company,
Attn:  Royalty Administration, D.C. 2211, Lilly Corporate Center, Indianapolis,
Indiana  46285.  In the event Roberts makes Sales of Product(s) to persons other
than End Users, Roberts shall require such persons to provide Roberts with such
information as Lilly may reasonably request to permit Lilly to calculate and
verify Net Sales and Royalties due.

     Section 7.02.  Delivery of Royalty.  When Roberts delivers the accounting
     ----------------------------------                                       
to Lilly, Roberts shall also pay by wire transfer or other method acceptable to
Lilly royalty payments due to Lilly for the preceding calendar quarter.  Any
payment not made when due shall bear interest at the United States prime rate on
due date as published in the Wall Street Journal, plus six percent (6%).
                             -------------------                        

     Section 7.03.  Audits.  Roberts shall keep accurate records in sufficient
     ---------------------                                                    
form to enable the amounts due to Lilly hereunder to be determined. during the
term of this Agreement and for two (2) years after its termination, shall not
more than once each year and upon written notice, have at its expense, to audit
the books and records of Roberts for the purpose of determining the accuracy of
royalty payments. If Roberts has underpaid a royalty amount due under this
Agreement by more than five percent (5%),
<PAGE>
 
                                     -8-
 
Roberts shall, in addition to paying any royalties due, also reimburse Lilly for
cost of such audit.

     Section 7.04.  Exchange Rates and Currency Translation.  All payments to be
     ------------------------------------------------------                     
made by Roberts to Lilly under this Agreement shall be made and reported in
United States dollars.  The rate of exchange to be used in computing the amount
of Net Sales and the United States dollars due Lilly will be calculated using
Roberts' then current standard exchange rate methodology, which methodology is
used by Roberts in the translation of its foreign currency operating results for
external reporting, is consistent with United States generally accepted
accounting principles and generally reviewed and approved by Roberts'
independent certified public accountants.

     Section 7.05.  Withholding Taxes.  Roberts shall have no liability for
     --------------------------------                                      
any income taxes levied against Lilly on account of royalties paid hereunder.
If any law regulations require that any such taxes be withheld by Roberts,
Roberts shall deduct such taxes from the payment due Lilly, pay the taxes so
withheld to the proper taxing authority, and send proof of payment to Lilly
annually within ninety (90) days of the first day of the year following such
payment. If Lilly desires to obtain a refund of any taxes so withheld and paid
from a taxing authority, Roberts shall cooperate in the pursuit of such refund.

                               LICENSE AGREEMENT
                                  [LY 315535]

     This License Agreement ("Agreement") is made as of the 4th day of December,
1996 by and between Eli Lilly and Company, an Indiana corporation ("Lilly") and
Roberts Laboratories Inc., a New Jersey corporation ("Roberts").

                                    RECITALS
                                    --------

     1. Lilly and Roberts are in the business of discovering, developing and
marketing pharmaceutical products.

     2. Lilly has discovered a compound internally designated as LY315535 (as
defined in Section 1.02 below, the "Compound") which may be useful in the
treatment of functional gastrointestinal disorders and other indications.  Lilly
has previously engaged in certain research and development efforts with respect
to the Compound, but has concluded that future development efforts including
limited clinical trials could best be conducted by a company with a focus on
gastrointestinal products.

     3. Roberts desires to license from Lilly certain rights of Lilly to the
Compound and to pursue development and commercialization of the Compound in the
Field and within the Territory (both as defined below), and Lilly is willing to
grant such license, all upon the terms and conditions set forth in this License
Agreement.

     4. Concurrently with the execution of this Agreement, Lilly is attempting
to enter into a License Agreement with Societe de Conseils de Recherches et
d'Applications Scientifiques ("Third Party") pursuant to which Lilly is
licensing to Third Party certain rights to develop and commercialize the
Compound outside the Territory.  Roberts and Third Party intend to enter into a
separate agreement among themselves providing for certain joint development
activities with respect to the Compound (the "Development Agreement").

                                   AGREEMENT

license under) patent term extensions, Supplementary Protection Certificates or
functional equivalents thereof, in any jurisdiction within the Territory where
such items are permissible, for any Lilly Intellectual Property Rights licensed
to Roberts hereunder.  Roberts will provide Lilly with all material and
information as may be necessary to obtain any of the aforesaid rights.

     Section 4.02.  Prosecution and Maintenance of Licensed Patents.
     -------------------------------------------------------------- 

     (a) Upon execution of this Agreement, Lilly shall provide to Roberts
     Appendix B attached hereto which identifies all pending applications and
     patents in the Territory which are encompassed in the Lilly Intellectual
     Property Rights.

     (b) Lilly shall prosecute any pending applications of which it is the owner
     that are encompassed in the Lilly Intellectual property Rights and maintain
     any patents that have issued or will issue thereon in full force and effect
     for the term of such patent.  Should, during the course of prosecution of
     any pending claims, an official action rejecting the claims require that an
     amendment be made or action be taken which would limit or substantially
     change the scope of any license 
<PAGE>
 
                                     -5-
 
     hereunder, Lilly will timely inform Roberts in writing. Lilly shall consult
     Roberts before responding to any such official action, and allow Roberts to
     assist in the prosecution of such claims or, at Lilly's option, allow
     Roberts the opportunity at its time and expense to prosecute such claims
     to its satisfaction.

     Section 4.03.  Costs of Prosecution and Maintenance of Patents.  Lilly
     --------------------------------------------------------------        
shall bear all costs incurred in filing, prosecuting and maintaining all patents
and patent applications encompassed within the Intellectual Property Rights,
provided, however, that Roberts shall pay one-half (1/2) of all reasonable
external expenses incurred by Lilly while prosecuting and maintaining such
patents and patent applications.  External expenses will include patent office
fees and taxes in connection with the prosection and maintenance of any patent
or patent application and the fees of any patent attorneys or agents, external
of Lilly, in connection with the ex parte prosection and maintenance thereof.
                                 -- -----                                     
The allocation of such expenses will occur on an annual basis at the end of the
last quarter of each calendar year, at which time Lilly will provide Roberts
with an itemized list of external expenses denominated in United States dollars
incurred during the previous annual period.  Roberts will then reimburse Lilly's
expenses within sixty (60) days of the date of receipt of this itemized list.
Notwithstanding the foregoing, Lilly may, at its sole discretion, choose not to
prosecute or cease to maintain a patent or patent application in any country as
it so desires and to the extent that Lilly chooses not to prosecute or ceases to
maintain such patent or patent application Lilly shall not be responsible for
any patent costs associated with prosecuting and/or maintaining the patent or
patent application in such country.  If Roberts desires to prosecute or maintain
such patent or patent application, Roberts may do so at its own expense;
however, under these circumstances, Lilly would grant Roberts all of its patent
rights associated which such patent in such country.  Similarly, upon written
notice to Lilly, Roberts may elect not to share in the prosecution or
maintenance costs as described in this Section 4.03 related to a patent or
patent application in a particular country; however, upon such election any
rights that Roberts has in such patent in such country would be granted to
Lilly.

     Section 4.04.  Option by Roberts to Discontinue License.  Roberts, at its
     -------------------------------------------------------                  
option, may elect to discontinue the license granted and surrender all rights
hereunder as to any patent on a country-by-country basis.  Such election must be
made by thirty (30) days written notice by simultaneous facsimile transmission
and certified mailing, and, with respect to the surrender of Roberts' rights,
will be effective as of the date of mailing.  In the event such an election is
made, Lilly's obligations under Section 4.01 and 4.02 and Roberts' obligations
under Section 4.03 will terminate thirty (30) days from the date of mailing with
respect to the specific patent on which the election is made.

     Section 4.05.  Infringement.  Each party shall give prompt notice to the
     ---------------------------                                             
other of any infringement, potential infringement or suspected infringement of
Lilly Intellectual Property Rights that may come to such party's attention.
Promptly thereafter, the parties shall consult and cooperate fully to determine
a course of action, including, but not limited to, the commencement of legal
action by one or both parties, to cause such infringement, potential
<PAGE>
 
                                     -6-
 
infringement or suspected infringement to be terminated.  Each party, at its
option, may elect to participate in or commence such a legal action.  In the
event of a joint action in which both parties agree to participate, the parties
will share in the costs and the recovery of the agreed upon course of action in
a manner to be agreed upon.  Failing agreement on a course of action to abate
infringement, potential infringement or suspected infringement within sixty (60)
days of the time such infringement, potential infringement or suspected
infringement becomes known to both parties, either party shall have the right,
at its own expense, to initiate and prosecute an action against the infringer
and shall retain whatever damages are recovered.  In the event Roberts is unable
to initiate and prosecute such action solely in its own name, Lilly will execute
(and cause its Affiliates to execute) all documents necessary for Roberts to
initiate and prosecute such action.  Neither party will enter into any
settlement of any action referred to in this Section without the other party's
prior consent, which consent shall not be unreasonably withheld.

     Section 4.06.  Reexamination and Reissue.  Lilly shall defend in a
     ----------------------------------------                          
reasonable manner any patent encompassed within the Lily Intellectual Property
Rights in any reexamination or reissue proceeding in the United States Patent
and Trademark Office and the applicable foreign equivalent.  Before Lilly
initiates a reissue proceeding, or before either party initiates a reexamination
proceeding, the parties shall consult as to the desirability or necessity of
such a proceeding.  Such proceedings will not be abandoned prior to a final
decision of the Patent Office Board of Appeals or Patent Office Board of
Interferences and the applicable foreign equivalent without the consent of
Roberts, which consent will not be unreasonably withheld taking into
consideration, inter alia, the merits of the action of the Patent and Trademark
Office and the applicable foreign equivalent, priority dates provable by any
interference party (should an interference be involved), and the technological
and commercial important of the subject matter of the claims of the application
or patent involved expenses shall be borne as provided in Section 4.03.

                                   Article V
                                   ---------

     --------------------------------------                                    
Roberts or Lilly shall release any information to any third party with respect
to the existence and terms of this Agreement without the prior written consent
of the other party to this Agreement, except that Roberts may disclose the
existence (but not financial terms) of this Agreement to Third Party.

     This prohibition includes, but is not limited to, press releases,
educational and scientific conferences, promotional materials, governmental
filings, and discussions with lenders, investment bankers, public officials, and
the media.

     Section 5.02.  Releases Required by Law.  If either party determines a
     ---------------------------------------                               
release of information is required by law or governmental regulations, it shall
notify the other in writing at least ten (10) days (or such shorter period where
legally required) before the time 
<PAGE>
 
                                     -7-
 
of the proposed release. The notice shall include the exact text of the proposed
release, the time and manner of the release, and the basis for such party's
belief that disclosure is required. At the other party's request and before the
release, the party desiring to release information shall consult with the other
party on the necessity for the disclosure and the text of the proposed release.
In no event shall a release include information regarding the existence of terms
of this Agreement that is not required by law or governmental regulation without
the consent of the other party.

     Notwithstanding any other terms of this Agreement, either party shall be
permitted and allowed to provide a copy of this Agreement or any terms hereof or
otherwise provide any information with respect to the existence and terms of
this Agreement to appropriate governmental taxing or drug regulatory authorities
requested, without advance written notice or approval of the other party.

     ------------------------------                                        
efforts to develop and commercialize Products within the Territory.  Roberts may
abandon development efforts for the Compound at any time if in the reasonable
judgment of Roberts further development efforts are not justified.  If Roberts
so abandons development, it shall upon request, assign to Lilly or Lilly's
designee all intellectual property, records, data, clinical trial results and
other information relating to the Compound in return for which Lilly or its
designee shall pay to Roberts an amount equal to Roberts' total development
costs (including all out of pocket costs and reasonable internal costs).
Furthermore, upon execution of this Agreement, Roberts shall assume all

personnel, provide Roberts with such technical assistance, information and
advice regarding the use of Lilly Intellectual Property Rights and the Know-How
that may be reasonably necessary in connection with the manufacturing and
testing of the Compound and Product.  Lilly, at its expense, also agrees that
such assistance may include one (1) visit to the Roberts facilities (not to
exceed twenty-four (24) hours) located in New Jersey by at least one (1)
qualified member of Lilly's personnel to render on-site technical assistance.

quarter.  Such quarterly reports shall be in English and include the Net Sales
of products on a country-by-country basis (expressed in United States dollars or
computed under the provisions of Section 7.04 hereof), a sales forecast for each
quarter of the current calendar year, and contain such other information as
Lilly may from time to time reasonably request.  Annually, by October 1, Roberts
shall deliver to Lilly a sales forecast, by quarter, for the subsequent calendar
year.  All sales and royalty reports shall be directed to Eli Lilly and Company,
Attn: Royalty Administration, D.C. 2211, Lilly Corporate Center, Indianapolis,
Indiana 46285.  In the event Roberts makes sales of Products(s) to persons other
than End Users, Roberts shall require such persons to provide Roberts with such
information as Lilly may reasonably request to permit Lilly to calculate and
verify Net Sales and royalties due.

     Section 7.02.  Delivery of Royalty.  When Roberts delivers the accounting
     ----------------------------------                                       
to Lilly, Roberts shall also pay by wire transfer or other method acceptable to
Lilly royalty payments due to Lilly for the preceding calendar quarter.  Any
payment not made when due shall bear interest at the United States prime rate on
due date as published in the Wall Street Journal, plus six percent (6%).
                             -------------------                        

     Section 7.03.  Audits.  Roberts shall keep accurate records in sufficient
     ---------------------                                                    
detail to enable to amounts due to Lilly hereunder to be determined.  During the
term of this Agreement and for two (2) years after its termination, Lilly shall,
not more than once each year and upon written notice, have the right, at its
expense, to audit the books and records of Roberts for the purpose of
determining the accuracy of royalty payments.  If Roberts has underpaid a
royalty amount due under this Agreement by more than five percent (5%), Roberts
shall, in addition to paying any royalties due, also reimburse Lilly for the
cost of such audit.

     Section 7.04.  Exchange Rates and Currency Translation.  All payments to be
     ------------------------------------------------------                     
made by Roberts to Lilly under this Agreement shall be made and reported in
United States dollars.  The rate of exchange to be used in computing the amount
of Net Sales and the United States dollars due Lilly shall be calculated using
Roberts' then current standard exchange rate methodology, which methodology is
used by Roberts in the translation of its foreign currency operating results for
external reporting, is consistent with United States generally accepted
accounting principles and is reviewed and approved by Roberts' independent
certified public accountants.

     Section 7.05.  Withholding Taxes.  Roberts shall have no liability for any
     --------------------------------

                                     -9-
 
taxes levied against Lilly on account of royalties paid hereunder. If laws or
regulations require that any such taxes be withheld by Roberts, Roberts shall
deduct such taxes from the payment due Lilly, pay the taxes so withheld to the
proper taxing authority, and send proof of payment to Lilly annually within
ninety (90) days of the first day of the year following such payment. If Lilly
desires to obtain a refund of any taxes so withheld and paid to a taxing
authority, Roberts shall cooperate in the pursuit of such refund.

any of its material obligations under this Agreement, or fails to remedy such a
default within sixty (60) days after the other party sends written notice
detailing the substance of the default to the defaulting party, the injured
party may terminate this Agreement by written notice.  In the event Lilly elects
to terminate this Agreement by reason of any default by Roberts, the licenses
granted hereunder shall terminate.

<PAGE>
 
                                      -10-

            (a)   At the rate of seven percent (7%) of the first $100,000,000

            country until the earlier of (a) the expiration of the last to 
            expire of the Licensed Patents (if any) in such country with claims

            commercial sale of Roberts or its sublicensees of any Licensed

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

      5.1   Sales between or among Roberts, its Affiliates and its
            sublicensees shall not be subject to royalties under Section 4, but 
            in such cases royalties shall be calculated upon Net Sales to an 
            independent third party.  Roberts Pharmaceutical Corporation shall 
            be responsible for payment of any royalties accrued on sales of 
            Licensed Products to such independent third party through its 
            affiliates or sublicensees.

            Payment Computation Period within sixty (60) days after the end of

            accompanied by a report identifying the Licensed Product, the Net

<PAGE>
 
                                      -11-

      5.3   All payments to be made by Roberts to Pfizer under this Agreement 
            shall be made and reported in Dollars.  The rate of exchange to be 
            used in computing the amount of Net Sales and the Dollars due 
            Pfizer shall be calculated using Roberts' then current standard 
            exchange rate methodology, which methodology is used by Roberts in 
            the translation of its foreign currency operating results for 
            external reporting; is consistent with United States generally 
            accepted accounting principles and is reviewed and approved by 
            Roberts' independent certified public accountants.

            sublicensees for the account of Pfizer on amounts payable to Pfizer

            hereunder at the rates specified by applicable law.  In addition, 
            Roberts shall provide promptly to Pfizer receipts from the 
            government or taxing authority evidencing payment of such taxes.

      5.5   Roberts and its sublicensees shall keep full and accurate books and 
            records setting forth gross sales, Net Sales, and amounts payable 
            to Pfizer hereunder.  Roberts shall permit Pfizer, at Pfizer's 
            expense, by independent certified public accountants employed by 
            Pfizer and reasonably acceptable to Roberts upon written notice to 
            Roberts and no more than once a year, to examine such books and 
            records at any reasonable time, but not later than five (5) years 
            following the rendering of any such reports, accountings and 
            payments.  Such independent accountants shall not disclose to 
            Pfizer any of Roberts' cost data.  The opinion of said independent 
            accountants regarding such reports, accountings and payments shall 
            be binding on the parties hereto.  All amounts of Net Sales shall 
            be determined from the books and records of Roberts maintained in
            accordance with United States generally accepted accounting
            principles, consistently applied.

      5.6   Roberts shall pay interest to Pfizer upon any and all amounts 
            payable under Section 3 and 4 (including royalties that are 
            contested or overlooked but later 
<PAGE>
 
                                      -12-

            monthly variable interest rate of 1% above the prime lending rate of
            Citibank, N.A., New York, New York which was in effect on the first
            day of the preceding calendar month, such interest accruing from the
            date when such royalties are due and payable as provided herein to
            the date of payment.

SECTION  6 - Disclosure of Information

            calendar days after such delivery, Roberts shall either confirm its 
            receipt of all such Technical Information or specify which of such 
            Technical Information it has not received.  All such Technical 
            Information is subject to the disclaimers and caveats set forth on

            disclose to others or use for any purpose, other than in connection 
            with the discharge of its obligations or exercise of its rights 
            under this Agreement, any Technical Information supplied in writing

            its employees or (c) is disclosed in good faith to Roberts by a

            confidentiality obligations consistent with the provisions of this 
            Section 6.2, to the extent possible under applicable law.  Nothing 
            herein shall be deemed to prevent Roberts investigators

                                      -13-

            allow personnel of Roberts to visit facilities of Pfizer and its 
            Affiliates and to consult with their personnel, at mutually 
            agreeable times, to discuss and review such information.  In 
            addition, Pfizer agrees, at the request of Roberts and at Roberts'

            Roberts' manufacturing and research facilities, at mutually 
            agreeable times to discuss and review such information.

      6.4   During the term of this Agreement and for five (5) years after 
            expiration or termination hereof (except in case of termination by 
            Pfizer under Section 13), Pfizer shall keep confidential and not 
            disclose to others or use for any purpose, other than in connection 
            with the discharge of its obligations or exercise of its rights 
            under this Agreement, any know-how, data or information that are 
            owned by Roberts, directed to Licensed Products and disclosed in 
            writing by Roberts and marked "confidential"; provided, however, 
            the foregoing obligations of confidentiality and non-use shall not 
            apply to the extent that such know-how, data and information is:  
            (a) already known to Pfizer at the time of disclosure hereunder or 
            hereafter developed by Pfizer independent of any disclosure 
            hereunder as Pfizer can demonstrate by competent proof; or (b) 
            publicly known prior to or after disclosure hereunder other than 
            through acts or omissions of Pfizer or its employees; or (c) 
            disclosed in good faith to Pfizer by a third party under a 
            reasonable claim of right.  Nothing herein shall be deemed to 
            prevent Pfizer investigators from publishing the results of their 
            work.

      6.5   All Technical Information heretofore disclosed by Pfizer to Roberts 
            and any know-how, data and information disclosed by Roberts to 
            Pfizer shall be deemed to have been disclosed pursuant to this 
            Agreement and shall be subject to the provisions of 
<PAGE>
 
                                      -14-

            this Agreement,  including but not limited to Sections 6.3 and 6.4

SECTION 7 - Supply of Bulk Sampatrilat
- --------------------------------------

      7.1   Except as specified below, Roberts alone will be responsible for 
            manufacturing all Licensed Product needed to meet its developmental 
            and commercial requirements.  Pfizer will supply Roberts with 
            approximately 20 kilograms of bulk sampatrilat and will use 
            reasonable efforts to extend the period during which such bulk
            sampatrilat may be used under U.S. law and regulations in clinical
            studies such as by extending the shelf life of such bulk
            sampatrilat. The outcome of Pfizer's efforts to extend such period
            is not assured and will have no impact on either parties' rights or
            obligations under this Agreement.

      7.2   PFIZER EXPRESSLY DISCLAIMS ALL IMPLIED AND EXPRESS WARRANTIES 
            (INCLUDING WITHOUT LIMITATION THE WARRANTY OF MERCHANTABILITY) WITH 
            RESPECT TO THE BULK SAMPATRILAT IT SUPPLIES TO ROBERTS UNDER 
            SECTION 7.1

SECTION 8 - Prosecution, Maintenance and Extension of Patents
- -------------------------------------------------------------

      8.1   Pfizer and Roberts shall cooperate in connection with the continued 
            prosecution by Pfizer of the patent applications listed in Exhibit 
            1.7(a).  Such cooperation shall include, without limitation: (a) 
            Roberts shall have full access to all documentation, filings and 
            communications to or from the respective patent offices, and shall 
            be kept fully advised as to the status of all pending applications; 
            (b) Pfizer, its agents and attorneys will use their reasonable 
            efforts to secure grant of all the Licensed Patents and will 
            consult with Roberts in the event that any country rejects any of 
            the patent applications constituting Licensed Patents; and (c) 
            Pfizer, its agents and attorneys will give due consideration to all 
            suggestions and comments of Roberts regarding any aspect of such 
            patent prosecutions.

      8.2   In addition, Pfizer shall take all necessary steps and 
<PAGE>
 
                                      -15-

            pay all expenses necessary to maintain for the full life thereof all
            Licensed Patents. Pfizer and Roberts shall consult with each other
            during the term of this Agreement to determine a worldwide patent
            filing strategy. Roberts shall use reasonable efforts to reduce or
            eliminate patent prosecution and maintenance costs related to the
            Licensed Patents in countries where Roberts has no reasonable
            expectation of actively making, using or selling the Licensed
            Products.

      8.3   Unless Pfizer elects to do so, Roberts shall have the right, upon 
            consultation with Pfizer, to file on behalf of and as agent for 
            Pfizer all applications and filings and take all actions necessary 
            to obtain the benefits under the Drug Price Competition and Patent 
            Term Restoration Act of 1984 and any amendments thereof.  Pfizer 
            agrees to sign such further authorizations and instruments and take 
            such further actions as may be requested by Roberts to implement 
            the foregoing.

      8.4   Pfizer and Roberts shall cooperate to obtain Supplementary 
            Protection Certificates in Europe where possible and for this 
            purpose Roberts shall inform Pfizer promptly of any country which 
            grants regulatory approval for Licensed Products and, upon request, 
            shall provide Pfizer with a summary of the registration documents 
            or any other documents reasonably required by Pfizer for such 
            purpose.

      8.5   If any claim of a Licensed Patents becomes, within any country in 
            the Territory, the subject of a judgment, decree or decision of a 
            court, tribunal, or other authority of competent jurisdiction, 
            which judgment, decree, or decision is or becomes final (there 
            being no further right of review) and adjudicates the validity, 
            enforceability, scope, or infringement of the same, the 
            construction of such claim in such judgment, decree or decision 
            shall be followed thereafter in such country in determining whether 
            a product is licensed hereunder, not only as to such claim but also 
            as to all other claims to which such construction reasonably 
            applies.  If at any time there are two or more conflicting final 
            judgments, decrees, or decisions with respect to the 
<PAGE>
 
                                      -16-

            same claim, the decision of the higher tribunal shall thereafter
            control, but if the tribunal be of equal rank, then the final
            judgment, decree, or decision more favorable to such claim shall
            control unless and until the majority of such tribunals of equal
            rank adopt or follow a less favorable final judgment, decree, or
            decision, in which event the latter shall control.

      8.6   Roberts shall mark all Licensed Products made, used or sold under 
            the terms of this Agreement, or their containers, in accordance 
            with the patent laws of the country where made, used or sold.

SECTION 9 - Infringement Of Licensed Patents
- --------------------------------------------

      9.1   Roberts shall give Pfizer prompt notice of any infringement, 
            potential infringement or suspected infringement of the Licensed 
            Patents that may come to Roberts' attention.  Pfizer shall give 
            Roberts prompt notice of its intent to bring legal action against a 
            party for infringing the Licensed Patents.  Promptly after any such 
            notice, the party receiving the notice shall consult and cooperate 
            fully with the other to determine a course of action, including, 
            but not limited to, the commencement of legal action by one or both 
            parties, to cause such infringement, potential infringement or 
            suspected infringement to be terminated.  Each party, at its 
            option, may elect to participate in or commence such a legal 
            action. In the event of a joint action in which both parties agree
            to participate, the parties will share in the costs and the recovery
            of the agreed upon course of action in a manner to be agreed upon.
            Failing agreement on a course of action to abate infringement,
            potential infringement or suspected infringement within thirty (30)
            days of the time such infringement, potential or suspected
            infringement becomes known to both parties, either party shall have
            the right, at its own expense, (a) to initiate and prosecute an
            action against the infringer and retain whatever damages are
            recovered and (b) to take whatever other steps it shall deem
            advisable. In the event Roberts is unable to initiate and prosecute
            any such action solely in its own name, Pfizer will 
<PAGE>
 
                                      -17-

            execute all documents necessary for Roberts to initiate and
            prosecute such action and cooperate in such action, at the cost and
            expense of Roberts, and vice versa. Neither party will enter into
            any settlement of any action referred to in this Section 9.1 without
            the other party's prior consent, which consent shall not be
            unreasonably withheld.

      9.2   Roberts and Pfizer shall, at the other's request, take all action 
            necessary to assist in suits initiated under Section 9.1 (including 
            joining as a party).                                        

SECTION 10 - Representations, Warranties and Covenants
- ------------------------------------------------------

      10.1  Pfizer hereby represents and warrants to Roberts as follows:

            (a)   Pfizer has the corporate power and authority to execute and 
                  deliver this Agreement and to perform its obligations 
                  hereunder, and the execution, delivery and performance of 
                  this Agreement by Pfizer have been duly and validly 
                  authorized and approved by proper corporate action on the 
                  part of Pfizer, and Pfizer has taken all other action 
                  required by law, its corporate statutes, certificate of 
                  incorporation or by-laws or any agreement to which it is a 
                  party or to which it may be subject required to authorize 
                  such execution, delivery and performance.  Assuming due 
                  authorization, execution and delivery on the part of Roberts, 
                  this Agreement constitutes a legal, valid and binding 
                  obligation of Pfizer, enforceable against Pfizer in 
                  accordance with its terms, except as the enforceability 
                  thereof may be limited by applicable bankruptcy, insolvency, 
                  reorganization or other similar laws of general application 
                  relating to creditors' rights.

            (b)   To the best of Pfizer's knowledge, the execution and delivery 
                  of this Agreement by Pfizer and the performance by Pfizer 
                  contemplated hereunder will not violate any ordinance, law, 
                  decree or government regulation or any order of any court or 
<PAGE>
 
                                      -18-

                  other governmental department, authority, agency or 
                  instrumentality thereof.

            (c)   To the best of Pfizer's knowledge, as of the date hereof the 
                  issued Licensed Patents are valid and enforceable patents and 
                  are not being infringed.  In addition, Pfizer is the legal 
                  and beneficial owner of all the Licensed Patents and all of 
                  the Technical Information, and no other person, firm, 
                  corporation or other entity has any right, interest or claim 
                  in or to the Licensed Patents or Technical Information.

            (d)   Neither the execution and delivery of this Agreement nor the 
                  performance hereof by Pfizer requires Pfizer to obtain any 
                  permits, authorizations or consents from any governmental 
                  body or from any other persons, firm or corporation, and such 
                  execution, delivery and performance will not result in the 
                  breach of or give rise to any termination of any agreement or 
                  contract to which Pfizer may be a party or which otherwise 
                  relates to the Licensed Patents, Technical Information or the 
                  Licensed Products.

      10.2  Roberts hereby represents and warrants to Pfizer as follows:

            (a)   Roberts has the corporate power and authority to execute and 
                  deliver this Agreement and to perform its obligations 
                  hereunder, and the execution, delivery and performance of 
                  this Agreement by Roberts has been duly and validly 
                  authorized and approved by proper corporate action on the 
                  part of Roberts, and Roberts has taken all other action 
                  required by law, its certificate of incorporation or by-laws 
                  or any agreement to which it is a party or to which it may be 
                  subject required to authorize such execution and delivery.  
                  Assuming due authorization, execution and delivery on the 
                  part of Pfizer, this Agreement constitutes a legal, valid and 
                  binding obligation of Roberts, enforceable against Roberts in 
                  accordance with its 
<PAGE>
 
                                      -19-

                  terms, except as the enforceability thereof may be limited by
                  applicable bankruptcy, insolvency, reorganization or other
                  similar laws of general application relating to creditors'
                  rights.

            (b)   To the best of Roberts' knowledge, the execution and delivery 
                  of this Agreement and the performance by Roberts contemplated 
                  hereunder will not violate any state, federal or other 
                  statute or regulation or any order of any court or other 
                  governmental department, authority, agency or instrumentality 
                  of the United States.

            (c)   Neither the execution and delivery of this Agreement nor the 
                  performance hereof by Roberts requires Roberts to obtain any 
                  permits, authorizations or consents from any governmental 
                  body or from any other persons, firm or corporation, and such 
                  execution, delivery and performance will not result in the 
                  breach of or give rise to any termination of any agreement or 
                  contract to which Roberts may be a party.

      10.3  Pfizer disclaims any implied warranty that Licensed Products made 
            in accordance with Licensed Patents have commercial utility.

SECTION 11 - Indemnification
- ----------------------------

      11.1  Roberts agrees to indemnify, defend and hold Pfizer and its 
            directors, officers, agents and employees (the "Pfizer Parties") 
            harmless from all loss, damage, liability, claim of loss, lawsuit, 
            action, cost, fees (including reasonable attorneys' fees), 
            expenses, and other claims asserted against them or any of them for 
            any damage, injury or death arising directly or indirectly as a 
            result of the clinical or animal testing or use, manufacturing, 
            processing, packaging, marketing, sale, distribution or disposal of 
            Licensed Products, or the disposal of wastes produced in the course 
            of any of the foregoing activities in each case by Roberts or its 
            sublicensees; provided, however, (a) such loss, damage, liability, 
            claim, lawsuit or action 
<PAGE>
 
                                      -20-

            shall not be the result of the gross negligence or intentional
            misconduct on the part of the Pfizer Parties, and (b) that Pfizer
            shall give Roberts notice as soon as practicable of any such claim
            or action and that Roberts shall have the right to participate in
            any compromise, settlement or defense hereof.

SECTION 12 - Termination
- ------------------------

      12.1  This Agreement shall be effective as of the date first set forth 
            above and shall remain in effect for so long as Roberts is 
            obligated to make payments to Pfizer under Sections 3 and 4, unless 
            earlier terminated as provided herein.  The provisions of Sections 
            6 and 11 shall survive the expiration or termination of this
            Agreement. In addition, the provisions of the last sentence of
            Section 4.2 with respect to the fully paid-up Technical Information
            license shall survive the expiration of this Agreement.

SECTION 13 - Termination
- ------------------------

      13.1  Roberts shall have the exclusive option at any time to terminate 
            this Agreement in full for whatever reason upon ninety (90) days' 
            prior written notice to Pfizer.

      13.2  If either Roberts or Pfizer materially breaches or defaults in the 
            performance or observance of any of the provisions of this 
            Agreement, and such breach or default is not cured within sixty 
            (60) days after the giving of notice by the other party specifying 
            such breach or default, the other party shall have the right to 
            terminate this Agreement upon a further thirty (30) days notice.  
            If any representation or warranty of any party as contained in this 
            Agreement shall be materially incorrect or inaccurate, such shall 
            be deemed to be a material breach or default of this Agreement by 
            such party.

      13.3  Termination of this Agreement for any reason shall be without 
            prejudice to:  (i) the rights and obligations of the parties as 
            provided in Sections 6 and 11; (ii) Pfizer's right to receive all 
            payments accrued under 
<PAGE>
 
                                      -21-

            Sections 3 and 4 prior to the effective date of such termination;
            and (iii) any other remedies which either party may otherwise have.

      13.4  Upon any termination by Pfizer under Section 13.2, and to the 
            extent requested by Pfizer, Roberts shall, at its sole expense, 
            transfer to Pfizer all Technical Information delivered to Roberts 
            hereunder, all scientific and technical information developed by 
            Roberts regarding Licensed Products, all INDs, NDAs and other 
            governmental health registrations and approvals regarding Licensed 
            Products; provided, however, Pfizer shall not be entitled to any 
            rights under any Roberts patents or scientific or technical 
            information to the extent such do not relate to Licensed Products 
            as a single entity.

SECTION 14 - Force Majeure
- --------------------------

      14.1  Neither party shall be liable to the other for loss or damages or 
            shall have any right to terminate this Agreement for any default or 
            delay attributable to any force majeure event, including but not 
            limited to acts of God, acts of government, fire, flood, earthquake,
            strikes, labor, disputes, and the like, if the party affected shall
            give prompt notice of any such cause to the other party. The party
            giving such notice shall thereupon be excused from such of its
            obligations hereunder as it is thereby disabled from performing for
            so long as it is so disabled and for 60 days thereafter; provided,
            however, that such affected party commences and continues to take
            reasonable and diligent actions to cure such cause. Notwithstanding
            the foregoing, nothing in this Section 14.1 shall excuse or suspend
            the obligation to make any payment due hereunder in the manner and
            at the time provided. If a party's performance cannot be resumed
            within 180 days of its suspension, this Agreement may be terminated
            by the other party upon 30 days advance written notice.

SECTION 15 - Assignment
- -----------------------

      15.1  Except as expressly provided herein, neither party may 
<PAGE>
 
                                      -22-

            assign its rights and obligations under this Agreement except to an
            Affiliate without the prior written consent of the other, except a
            party may make such an assignment without the other party's consent
            in connection with any merger or sale of all or substantially all of
            its assets to which this Agreement relates. This Agreement shall be
            binding upon and inure to the benefit of the successors and
            permitted assignees of the parties hereto. If any assignment of this
            Agreement occurs, the assignor shall remain liable for all payments
            and obligations hereunder of the assignee.

SECTION 16 - Option Rights Retained by Pfizer
- ---------------------------------------------

      16.1  First Option Period Negotiations
            --------------------------------

            (a)   Evaluation Period.  At any time during the First Option 
                  -----------------
                  Period, if Pfizer is interested in initiating the 
                  negotiations referred to in Section 16.1(c), Pfizer may elect 
                  to initiate an evaluation period by giving written notice to 
                  Roberts of its desire to initiate such evaluation period.

            (b)   Roberts' Obligations during the Evaluation Period.  If 
                  -------------------------------------------------
                  Pfizer elects to initiate the evaluation period pursuant to

              REPRESENTATIONS AND WARRANTIES OF ROBERTS' AND PHCG
              ---------------------------------------------------

         Roberts and PHCG each hereby represents and warrants to Purchaser and
Parent as follows:

     SECTION 5.01.  CORPORATE STATUS.
                    ---------------- 

     Roberts is a corporation duly organized, validly existing, and in good
standing under the laws of the State of New Jersey.  Each of PHCG New York and
PHCG New Jersey is a corporation duly organized, validly existing and in good
standing under the laws of the States of New York (in the case of PHCG New York)
and New Jersey (in the case of PHCG New Jersey), and each has the requisite
corporate power and authority to own or lease their respective Assets and to
operate the Business in their respective jurisdictions of incorporation. Each of
PHCG New Jersey and PHCG New York is duly qualified or licensed to do business
as a foreign corporation and is in good standing in any jurisdiction wherein the
character of property owned or leased or the nature of the activities conducted
by it makes such qualification or licensure necessary.

     SECTION 5.02.  AUTHORITY AND APPROVAL.
                    ---------------------- 

     Each of Roberts and PHCG has full power and authority to enter into this
Agreement and to assume and perform its obligations hereunder.  This Agreement
and the agreements and transactions contemplated hereby have been approved and
authorized by the Boards of Directors of Roberts and PHCG, and constitute valid,
binding and enforceable obligations of Roberts and PHCG, except to the extent
the enforceability thereof may be limited by applicable bankruptcy, insolvency,
reorganization, equitable principles or similar laws affecting legal or
equitable rights generally.  No action, approval, consent or authorization with
respect to Roberts is required, which has not already been taken or obtained, in
order to constitute this Agreement as a binding and enforceable obligation of
Roberts and PHCG in accordance with its terms.

     SECTION 5.03.  NO VIOLATION.
                    -------------

                                       15
<PAGE>
 
     Neither the execution and delivery of this Agreement by Roberts and PHCG,
nor the performance of Roberts' and PHCG's obligations hereunder, will violate,
conflict with, or constitute a default under, any of the terms of the
Certificates or Articles of Incorporation or by-laws of Roberts, PHCG New Jersey
or PHCG New York, or any provisions thereof, or result in the acceleration of
any obligation under any contract, sales commitment, license, purchase order,
security agreement, mortgage, note, deed, lien, lease, agreement, instrument,
order, judgment or decree to which Roberts, PHCG New Jersey or PHCG New York is
a party or by which Roberts, PHCG New Jersey, PHCG New York, the Premises, or
the Assets are bound, and will not constitute an event which, after the giving
of notice or lapse of time or both, will result in such violation, conflict,
default or acceleration.  The execution and delivery of this Agreement and the
performance by Roberts and PHCG of the transactions contemplated hereby will not
result in the creation or imposition of any Encumbrances in favor of any third
person or entity upon the Premises or the Assets and will not violate any law,
judgment, decree, order, rule or regulation of any Governmental Authority
applicable to Roberts, PHCG New Jersey, PHCG New York, the Premises, or the
Assets.

     SECTION 5.04.  TITLE.
                    ----- 

     PHCG is the owner of and has good and marketable title to the Assets, free
and clear of any and all Encumbrances, except as expressly set forth on Schedule
                                                                        --------
H and as contemplated in Section 2.02 above with respect to the Premises.
- -                                                                        

     SECTION 5.05.  CONTRACTS AND COMMITMENTS.
                    ------------------------- 

     Each of the Contracts, the Personal Property Leases and the Real Property
Leases is a valid and binding agreement, enforceable according to its terms and
is in full force and effect, and all obligations thereunder shall be paid in
full through the end of the calendar month in which the First Closing Date
occurs.  Neither PHCG nor Roberts has breached or terminated or is in default
under any of the Contracts, the Personal Property Leases or the Real Property
Leases and there exists no condition or event which, after notice or lapse of
time or both, would constitute any such breach, termination or default.  To the
best of Roberts' and PHCG's knowledge and belief, no other party to any such
Contract, Personal Property Lease or Real Property Lease has breached,
terminated or is in default under such Contract, Personal Property Lease or Real
Property Lease, and there exists no condition or event which, after notice or
lapse of time or both, would constitute any such breach, termination, or
default.

     Except as set forth on Schedules A, D and E, PHCG has no agreements or
                            -----------  -     -                           
obligations, and is not a party with respect to, any written (i) lease; (ii)
royalty, distribution, manufacturing, research or license agreement; (iii)
contract or agreement (for employment or otherwise); with any officer, employee,
director, professional person or firm, consultant, independent contractor or
advertising firm or agency which is not terminable without payment or other
penalty on notice from PHCG of not more than 30 days; (iv) contract or
collective bargaining agreement with any labor union or representative of
employees; (v) commitment, contract or agreement guaranteeing the payment or
performance of the obligations or others; (vi) group health or life insurance,
pension, profit sharing, retirement, medical, bonus, incentive plan, or other
similar benefit plan in effect with respect to its employees or others; (vii)
loan agreement, line of credit or other credit commitment to banks, other
financial institutions, or to

                                       16

any of Roberts or any third parties; (viii) commitment, contract or agreement
not made in the ordinary course of business; (ix) contract or agreement relating
tot he provision of home infusion therapy or the supply of pharmaceutical
products and supplies in connection therewith; or (x) contract or agreement
continuing for more than 180 days from its date.  Except as set forth therein,
no consent of any party is required under any document listed on Schedules A, D
                                                                 -----------  -

this Agreement or any agreement entered into in connection herewith.  The
consummation of the transactions contemplated by this Agreement or any agreement
executed in connection herewith will not violate the terms or provisions of any
agreement to which PHCG is a party, cause the acceleration of the maturity of
any debt or obligation of PHCG or result in the creation or imposition of any
Encumbrance upon any of the Assets.

     SECTION 5.06.  FINANCIAL STATEMENTS.
                    -------------------- 

     Roberts and PHCG have heretofore delivered to Purchaser unaudited financial
statements for PHCG as of and for the year ending December 31, 1995, and as of
and for the nine month period ending September 30, 1996.  Said financial
statements fairly and accurately present the financial condition of PHCG and the
Business as of the respective dates and for the periods indicated therein and
have been prepared in accordance with generally accepted accounting principles
consistently applied.  All of the foregoing financial statements are hereinafter
referred to as the "PHCG Financial Statements".  Copies of the PHCG Financial
                    -------------------------                                
Statements are set forth in Schedule I.  Since June 13, 1994, PHCG has kept its
                            ----------                                         
accounting records in a consistent manner, and the books of account of PHCG have
been regularly kept and maintained in conformity with generally accepted
accounting practices.

     SECTION 5.07.  RECORDS.
                    -------

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

to the date hereof, have been furnished to Purchaser.

     SECTION 5.09.  TAXES.
                    ----- 

     Except as set forth on Schedule J PHCG has duly filed all foreign, federal,
                            ----------                                          
state, county and local, income, excise, sales, property, withholding, social
security, franchise, license and information tax returns and other tax returns
and reports required to have been filed by it to the date hereof.  Each such
filed return is correct and complete and PHCG has paid all taxes, assessments,
interest and penalties due to any foreign, federal, state, county, local or
other taxing authority required to be paid by it and has created sufficient
reserves or made provision for all taxes accrued but not yet due and payable by
it.  Neither Roberts nor PHCG know of any basis for any additional tax claims or
assessments which are material singly or in the aggregate,

                                       17
<PAGE>
 
other than as may be shown on the PHCG Financial Statements.  Since June 13,
1994, none of the tax returns of PHCG has been audited by the Internal Revenue
Service or any other authority levying or collecting taxes.  No Governmental
Authority is now asserting or, to the best knowledge of either Roberts or PHCG,
threatening to assert, any deficiency or assessment for additional taxes or any
interest, penalties or fines with respect to PHCG.  Complete and correct copies
of all federal income tax returns filed by PHCG, as well as any other tax
returns of PHCG requested in writing by Purchaser have been heretofore delivered
to the Purchaser.

     SECTION 5.10.  LITIGATION.
                    ---------- 

     There exists no litigation, action, suit, investigation, claim or
proceeding pending or, to the best of Roberts' or PHCG's knowledge and belief,
threatened against or adversely affecting, Roberts, PHCG, the Business, the
Premises, or the Assets, at law or in equity or before any Governmental
Authority that would materially affect the Business, the transactions
contemplated by this Agreement or the ability of Roberts or PHCG to perform
their respective obligations hereunder.  Neither Roberts nor PHCG is in default
with respect to any order, writ, injunction or decree of any court or any
Governmental Authority.

     SECTION 5.11.  COMPLIANCE.
                    ---------- 

     Neither PHCG nor Roberts has failed to comply with any law or any other
requirement of any Governmental Authority that would prevent Purchaser from
conducting the Business following the First Closing (in the case of PHCG New
Jersey) and the Second Closing (in the case of PHCG New York, except to the
extent such failure was caused (after the First Closing) by acts or omissions of
Purchaser or any Affiliate of Purchaser) on substantially the same terms as it
is currently being operated by PHCG, and PHCG has complied in all material
respects with all laws (including, but not limited to, the Food, Drug and
Cosmetic Act, the provisions of Medicare and Medicaid and any state or Federal
law with respect to health care or the supplying or dispensing of pharmaceutical
products), orders and regulations of any Governmental Authority (including but
not limited to the Food and Drug Administration and the New Jersey and New York
Departments of Health) applicable to it.  Except as set forth on Schedule K
                                                                 ----------
there are no orders, decrees, injunctions or regulations of any court or any
Governmental Authority issued specifically against or affecting Roberts or PHCG
which may materially affect, limit or control Purchaser's method or manner of
operating the Business or Roberts' or PHCG's ability to consummate the
transactions contemplated hereunder.

     SECTION 5.12.  PERMITS.

well as a true and complete list of all suppliers of PHCG.  Neither Roberts nor

license or other authorization with respect to any Federal, State or local law

with the Business which reasonably could be expected to give rise to common law
or statutory liability for damages or injunctive relief against PHCG.  No
premises owned or leased by PHCG contain any hazardous substance (as defined
below) other

used and stored in compliance with all applicable laws;  PHCG has not conducted
or authorized the generation, transportation, storage, treatment or disposal of
any hazardous substance other than that required in the ordinary course of the

threatened litigation or proceedings before any Governmental Authority in which
any Person alleges the presence, release, threat of release, placement on or in
the Premises or any real property leased by PHCG, or the generation,
transportation, storage, treatment or disposal on or in any such premises, of
any hazardous substance.  No Governmental Authority or any employee or agent
thereof has determined, or, to the knowledge of Roberts or PHCG, threatens to
determine, that there is a presence, release, threat of release, placement on or
in the Premises or any real property leased by PHCG, or the generation,
transportation, storage, treatment, or disposal at such premises, of any
hazardous substance.  There have been no communications or agreements with any
Governmental Authority or any private entity, including, but not limited to, any
prior owners of the Premises or any real property leased by PHCG, relating in
any way to the presence, release, placement on or in such premises, or the
generation, transportation, storage or treatment or disposal at such premises,
of any hazardous substance.  For purposes of this Section 5.22, "hazardous
substance" means any matter giving rise to liability under the Resources
Conversation Recovery Act, 42 U.S.C. Sections 6901 et seq., the Comprehensive
                                                   -- ----

any of the representations or warranties made herein not misleading.  The copies
of all instruments, agreements, other documents and written information referred

     Neither the execution and delivery of this Agreement by Purchaser and
Parent nor the performance of Purchaser's or Parent's obligations hereunder will

acknowledge and deliver all such other instruments and documents of sale,
assignment, conveyance and transfer and shall take all such other action as may
be required by Purchaser, in its sole reasonable discretion, for the
consummation of the transactions contemplated hereby.  Roberts and PHCG shall
each, and Roberts shall, prior to the First Closing (in the case of PHCG New
Jersey) and Second Closing (in the case of PHCG New York), cause PHCG to, use
its best respective efforts to assist Purchaser in securing, any consent, waiver
or approval from any Governmental Authority which may be required for the
consummation of the transactions contemplated hereby.  After the First Closing

connection with any investigation, audit, litigation or other proceeding
relating to the operations of PHCG.

     Risk of loss to the Premises or any part thereof, shall be and remain on
Robert and PHCG until the First Closing.  If the Premises, or any part thereof,
shall be damaged or destroyed by any casualty whatsoever prior to the First
Closing, Roberts shall notify Purchaser within five days thereafter and the
parties shall proceed as follows:

     (a) Within 30 days after the occurrence of any damage or destruction
referred to in this Section 9.04, Roberts shall obtain and deliver to Purchaser
a written estimate from a responsible reputable contractor doing business in the
State of New York (the selection of said contractor to be subject to Purchaser's
written approval) of the cost for repairing such damage or destruction;

     (b) If the cost of repair of such damage or destruction as determined
pursuant to subparagraph (a) shall be $100,000 or less, the obligations of the
parties hereunder shall not be affected by such damage or destruction, except
Purchaser shall be entitled to receive a credit against the Purchase Price in an
amount equal to the cost of such repair as determined pursuant to subparagraph
(a) of this Section 9.04 (which credit shall be reduced to the extent of any
insurance proceeds paid over by Roberts to PHCG or Purchaser); and

     (c) If the cost of repair of such damage or destruction as determined
pursuant to subparagraph (a) shall be more than $100,000, Purchaser shall have
the right to (i) elect to terminate this Agreement, and thereupon the parties
shall be fully released and discharged from any further liability or obligations
hereunder, each to the other except as set forth in Section 11.08, or (ii)
accept the Premises in their damaged condition, with no abatement in the
Purchase Price, provided that all insurance proceeds payable or paid with
respect to such damage or destruction shall be assigned by Roberts and/or PHCG,
as the case may be, and paid over to Purchaser at the First Closing.

     SECTION 9.05.  CONDEMNATION.
                    ------------ 

     In the event of any condemnation of the Premises, or any material part
thereof, prior to the First Closing, Roberts shall notify Purchaser within five
days thereafter and Purchase shall have the right to elect within ten days of
such notice either (a) to proceed with the First Closing, without any credit
against the Purchase Price, but in which event Purchaser shall be entitled to
receive the proceeds of the condemnation, or (b) to withdraw from this Agreement
and the transactions contemplated hereunder, and thereupon the parties hereto
shall be fully released and discharged from any further liability or obligation
hereunder, each to the other except as set forth in Section 11.08.  In the event
that Purchaser does not provide Roberts with notice of its election within the
ten day period as provided for in this Section, Purchaser shall be deemed to
have elected to proceed with the Closing pursuant to subsection (a) of this
Section 9.05.

     SECTION 9.06.  CONFIDENTIALITY.
                    --------------- 

     The parties hereto agree that they will not, without the prior written
consent of the other parties hereto, issue, give or make any press release,
notification or disclosure to any third party or to the public, in each case
relating to this Agreement or any of the terms or conditions hereof or any of
the transactions contemplated hereby, except as required to perform

approval required by this Agreement, until the Second Closing or earlier
termination of this Agreement.  Roberts and PHCG each agrees, and Roberts agrees
to cause PHCG, to obtain the prior written approval of Purchaser before making
its initial public announcements or disclosures following the Second Closing
with respect to this Agreement and the transactions contemplated hereby.

     SECTION 9.07.  SALES AND OTHER TAXES.
                    --------------------- 

     Roberts agrees to pay all sales taxes, if any, on the sale of the Assets
which may become due and owing as a result of the transactions contemplated by
this Agreement, provided, however, that Purchaser shall pay all transfer taxes
                --------  -------

PHCG New York shall, and Roberts shall cause PHCG New York to, repay to
Purchaser the Loans in full, together with interest thereon at a rate equal to
8% per annum, accruing from the date of each such advance, through and including
the date of repayment; provided, however, that such obligation of PHCG New York
                       --------  -------

                                         -------- -------              
repayment obligation shall only apply to Loans consented to by Roberts and (ii)
Roberts hereby consents to all Loans from Purchaser to PHCG New York which do
not at any time exceed $350,000 in the aggregate principal amount outstanding.

reasonably required by Purchaser to obtain the approval of any Governmental

executed amendments to the corporate charters of PHCG New Jersey and PHCG New
York substantially in the forms attached hereto as Exhibits N and O (together,
                                                   -------- -     -

Date. Any indemnification payment made pursuant to the foregoing will include

     10.3 Indemnification by Company and Buyer. Subject to the provisions of
          -------------------------------------

     10.4 Rules Regarding Indemnification. The obligations and liabilities of
          --------------------------------                                   
each party which may be subject to indemnification liability hereunder (the
"indemnifying party") to the other party (the "indemnified party") will be
subject to the following terms and conditions:

          (1) Claims by Non-parties. The indemnified party will give written
              ----------------------                                        
notice within a reasonably prompt period of time to the indemnifying party of
any written claim by a third party which is likely to give rise to a claim by
the indemnified party against the indemnifying party based on the indemnity
agreements contained

                                       28
<PAGE>
 
in this Article, stating the nature of said claim and the amount thereof, to the
extent known.  The indemnified party will give notice to the indemnifying party
that pursuant to the indemnity, the indemnified party is asserting against the
indemnifying party a claim with respect to a potential loss from the third party
claim, and such notice will constitute the assertion of a claim for indemnity by
the indemnified party.  If, within twenty (20) days after receiving such notice,
the indemnifying party advises the indemnified party that it will provide
indemnification and assume the defense at its expense, then so long as such
defense is being conducted, the indemnified party will not settle or admit
liability with respect to the claim and will afford to

the indemnifying party and defending counsel reasonable assistance in defending
against the claim.  If the indemnifying party assumes the defense, counsel will
be selected by such party and if the indemnified party then retains its own
counsel, it will do so at its own expense.  If the indemnified party does not
receive a written objection to the notice from the indemnifying party within
twenty (20) days after the indemnifying party's receipt of such notice, the
claim for indemnity will be conclusively presumed to have been accepted to and
approved, and in such case the indemnified party may control the defense of the
matter or case and, at its sole discretion, settle or admit liability.  If
within the aforesaid twenty (20) day period the indemnified party will have
received written objection to a claim (which written objection will briefly
describe the basis of the objection to the claim or the amount thereof, all in
good faith), then for a period of sixty (60) days after receipt of such
objection the parties will attempt to settle the dispute as between the
indemnified and indemnifying parties.  If they are unable to settle the dispute,
the unresolved issue or issues will be settled by arbitration in accordance with
the rules and procedures of the American Arbitration Association.  If the
indemnified party is Buyer or Company, such arbitration will be conducted in
Nashville, Tennessee, and if the indemnified party is Shareholder, such
arbitration will be conducted in New York, New York.

          (2) Claims by a Party. The determination of a claim asserted by a
              ------------------                                           
party hereunder (other than as set forth in subparagraph (1) above) pursuant to
this Article will be made as follows: The indemnified party will give written
notice within a reasonably prompt period of time to the indemnifying party of
any claim by the indemnified party which has not been made pursuant to
subparagraph (1) above, stating the nature and basis of such claim and the
amount thereof, to the extent known. The claim will be deemed to have resulted
in a determination in favor of the indemnified party and to have resulted in a
liability of the indemnifying party in an amount equal to the amount of such
claim estimated pursuant to this paragraph if within thirty (30) days after the
indemnifying party's receipt of the claim the indemnified party will not have
received written objection to the claim.  In such event, the claim will be
conclusively presumed to have been assented to and approved.  If within the
aforesaid thirty (30) day period the indemnified party will have received
written objection to a claim (which written objection will briefly

                                       29
<PAGE>
 
describe the basis of the objection to the claim or the amount thereof, all in
good faith), then for a period of sixty (60) days after receipt of such
objection the parties will attempt to settle the disputed claim as between the
indemnified and indemnifying parties.  If they are unable to settle the disputed
claim, the unresolved issue or issues will be settled by arbitration in
accordance with the rules and procedures of the American Arbitration
Association.  Notwithstanding the provisions of this clause (2), the enforcement
provisions set forth in paragraph 11.2  will be available in the event of a
breach of paragraph 11.1.  If the indemnified party is Buyer or Company, such
arbitration will be conducted in Nashville, Tennessee, and if the indemnified
party is Shareholder, such arbitration will be conducted in New York, New York.

          (3) Claims by a Straddle Patient. Any claim by a patient relating to
              -----------------------------                                   
professional negligence or similar matters involving a patient served both prior
to the Effective Date and subsequent to the Effective Date will be the
responsibility of either Company or Shareholder in accordance with the following
guidelines: (i) if it is a claim in which the incident giving rise to
allegations of liability clearly arose prior to the Effective Date, Shareholder
will respond to the loss and defense expenses; (ii) subject to the other
provisions of this Agreement, if it is a claim in which the incident giving rise
to allegations of liability clearly arose on or after the Effective Date,
Company will respond to the loss and defense expenses; and (iii) if the incident
giving rise to allegations of liability is not clear as to time, Shareholder and
Company will jointly defend the case and each will fully cooperate with the
other in such defense.  Once the case is closed, if Buyer, Company and
Shareholder cannot agree to the allocation of both indemnity and expenses, then
the matter will be submitted to binding arbitration in New York, New York in
accordance with the rules and procedures of the American Arbitration
Association.


                      ARTICLE XI. PRESERVATION OF BUSINESS
                          AND NONCOMPETE RESTRICTIONS

     11.1 Covenant Not to Compete. Shareholder hereby covenants and agrees with
          ------------------------                                             
Buyer that, during the NON-COMPETE PERIOD (as such term is defined herein) and
within the NON-COMPETE AREA (as such term is defined herein), Shareholder will
not directly or indirectly, (a) acquire, lease, manage, consult for, serve as
agent or subcontractor for, finance, invest in, own any part of or exercise
management control over any health care operation or business which provides any
goods or services competitive with the goods and services provided by the
Business as of the Closing, or (b) solicit for employment or employ any person
who at Closing or thereafter became an employee of Buyer, Company or an
affiliate unless such person is not so employed for at least six (6) months, or
(c) with respect to any customer, patient, physician, physician group, or
healthcare provider with whom Buyer, Company and/or an Affiliate contracts with
in connection with the Business, either solicit the same in a manner which could
adversely affect Buyer, Company or an Affiliate, or make

                                       30
<PAGE>
 
statements to the same which disparage Buyer, Company, an Affiliate or their
respective operations in any way.  The "Non-Compete Period" will commence at the
Closing and terminate on the fifth (5th) anniversary thereof.  The "Non-Compete
Area" will mean the area within a fifty (50) mile radius of each location from
which the Business is operated or conducted as of the Closing.  Ownership of
less than five percent (5%) of the stock of a publicly held company will not be
deemed a breach of this covenant.

     11.2 Enforceability. In the event of a breach of paragraph 11.1,
          ---------------                                            
Shareholder recognizes that monetary damages will be inadequate to compensate
Buyer and Company, and Buyer and Company will be entitled, without the posting
of a bond or similar security and notwithstanding the arbitration provisions
contained in Article X, to an injunction restraining such breach, with the costs
(including attorney's fees) of securing such injunction to be borne by
Shareholder.  Nothing contained herein will be construed as prohibiting Buyer or
Company from pursuing any other remedy available to either for such breach or
threatened breach.  All parties hereby acknowledge the necessity of protection
against the competition of Shareholder and that the nature and scope of such
protection has been carefully considered by the parties.  The period provided
and the area covered are expressly represented and agreed to be fair, reasonable
and necessary. The consideration provided for herein is deemed to be sufficient
and adequate to compensate Shareholder for agreeing to the restrictions
contained in paragraph 11.1.  If, however, any court determines that the
forgoing restrictions are not reasonable, such restrictions will be modified,
rewritten or interpreted to include as much of their nature and scope as will
render them enforceable.


                           ARTICLE XII. MISCELLANEOUS

     12.1 Assignment. Following Closing, Buyer and Company may freely assign any
          -----------                                                           
or all of their respective rights or delegate any or all of their respective
obligations under this Agreement to any Affiliate without the express written
consent of Shareholder.  Buyer and Company may not assign any rights or delegate
any obligations under this Agreement to any other party without the prior
written consent of Shareholder, and Shareholder may not assign any rights or
delegate any obligations under this Agreement without the prior written consent
of Buyer.  Any prohibited assignment or delegation will be null and void.
Subject to the foregoing, this Agreement will be binding upon and inure to the
exclusive benefit of the parties hereto and their respective legal
representatives, successors and assigns. This Agreement is not intended to nor
will it, create any rights in any other party.

     12.2 Other Expenses. Except as otherwise provided in this Agreement,
          ---------------                                                
Shareholder will pay all of its and Company's expenses in connection with the
negotiation, execution, and implementation of the transactions contemplated
under this Agreement and Buyer will pay all of its expenses in connection with
the negotiation, execution, and implementation of the transactions contemplated
under

                                       31
<PAGE>
 
this Agreement.  All sales and use taxes, recording fees and transfer taxes
incurred in connection under the transactions contemplated within this Agreement
will be borne by Shareholder and paid at Closing.

     12.3 Notices. All notices, requests, demands, waivers and other
          --------                                                  
communications required or permitted to be given under this Agreement will be in
writing and will be deemed to have been duly given: (a) if delivered personally
or sent by facsimile, on the date received, (b) if delivered by overnight
courier, on the day after mailing, and (c) if mailed, five days after mailing
with postage prepaid.  Any such notice will be sent as follows:

          To Shareholder and, prior to Closing, Company:

     12.4 Confidentiality; Prohibition on Trading. Except for press releases
          ----------------------------------------                          
issued by Buyer and Shareholder in the ordinary course following Closing, all
parties agree to maintain the confidentiality of the existence of this Agreement
and the transactions contemplated hereunder, unless disclosure is required by
law.  Both Buyer and Shareholder will provide the other a copy of such press
release two (2) business days prior to issuance for review and comment.  Each
party and its Affiliates agree not to trade in the securities of the other
parties based upon any nonpublic information.

     12.5 Partial Invalidity: Waiver. The invalidity or unenforceability of any
          ---------------------------                                          
particular provision of this Agreement will not affect the other provisions
hereof, and this Agreement will be construed in all respects as if such invalid
or unenforceable provisions were omitted.  Further, there will be automatically
substituted for such invalid or unenforceable provision a provision as similar
as possible which is valid and enforceable.  Neither the failure nor any delay
on the part of any party hereto in exercising any rights, power or remedy
hereunder will operate as a waiver thereof, or of any other right, power or
remedy; nor will any single or partial exercise of any right, power or remedy
preclude any further or other exercise thereof, or the exercise of any other
right, power or remedy. No waiver of any of the provisions of this Agreement
will be valid unless it is in writing and signed by the party against which it
is sought to be enforced.

     12.6 Interpretation; Knowledge. All pronouns and any variation thereof will
          --------------------------                                            
be deemed to refer to the masculine, feminine, neuter, singular or plural as the
identity of the person or entity, or the context, may require.  Further, it is
acknowledged by the parties that this Agreement has undergone several drafts
with the negotiated suggestions of both; and, therefore, no presumptions will
arise favoring either party by virtue of the authorship of any of its provisions
or the changes made through revisions.  Any table of contents and paragraph
headings in this Agreement are for convenience of reference only and will not be
considered or referred to in resolving questions of interpretation.  Whenever in
this Agreement the term "to the best knowledge of Company or Shareholder" or the
like is used, Company and Shareholder will each be deemed to have the knowledge
of its respective officers and directors; and Company and Shareholder will each
be under a duty of due inquiry.

     12.7 Entire Agreement; Counterparts. This Agreement, including the Exhibits
          -------------------------------                                       
and Attachments hereto, constitutes the entire agreement between the parties
hereto with regard to the matters contained herein and it is understood and
agreed that all previous undertakings, negotiations, letters of intent and
agreements between the parties related to the subject matter hereof are merged
herein. This Agreement may not be modified orally, but only by an agreement in
writing signed by Buyer, Company and Shareholder.  This Agreement may be
executed simultaneously in two or more counterparts each of which will be deemed
an original and all of which together will constitute one and the same
instrument.

     12.8 Further Assurance of Shareholder After Closing.  Subsequent to the
          -----------------------------------------------                   
Closing, Shareholder will from time to time, at Buyer's request, execute and
deliver such other instruments of conveyance and transfer, and take such other
action as Buyer may reasonably request, in order more effectively to sell,
transfer, assign and deliver and vest in Buyer and Company, as the case may be,
the benefits of, title to and possession of the Stock and Assets.

                                       33

     12.9 Legal Fees and Costs. If any party hereto incurs legal expenses to
          ---------------------                                             
enforce or interpret any provision of this Agreement, the prevailing party will
be entitled to recover such legal expenses, including, without limitation,
attorney's fees, costs and disbursements, in addition to any other relief to
which such party may be entitled.

     12.10 Controlling Law.  This Agreement will be construed, interpreted and
enforced in accordance with the substantive laws of the State of Tennessee,
without giving effect to its conflicts of laws provisions.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the date first above written.
