PART I
ITEM 1.  BUSINESS

OVERVIEW

         Watson Pharmaceuticals, Inc., incorporated in 1985, is engaged in the
development, production, marketing and distribution of off-patent and branded
pharmaceutical products. Unless otherwise specified, reference to "Watson" or
the "Company" shall refer to Watson Pharmaceuticals, Inc. and its subsidiaries
and excludes The Rugby Group, Inc. (as discussed below).

OFF-PATENT PHARMACEUTICALS

         The Company is recognized as one of the leaders in the off-patent
pharmaceutical industry. Pharmaceutical products initially sold on an exclusive
basis are known in the industry as branded (or proprietary) products. Off-patent
drugs are therapeutically equivalent to their brand name counterparts and are
generally sold at prices significantly less than branded products. Accordingly,
off-patent pharmaceuticals provide a safe, effective and cost efficient
alternative to users of these products.

BRANDED PHARMACEUTICALS

         The Company's branded pharmaceutical business is focused primarily on
three therapeutic areas: Dermatology, Women's Health and NeuroPsychiatry. Watson
has strategically focused on these markets due to their perceived growth
opportunities. The nature of these markets and the identifiable base of
physician prescribers allow the Company to achieve significant market
penetration through its specialized sales forces.

         The Company also markets several products that are promoted to primary
care physicians around the country. These products include two hypertension
products and a pain management drug. Watson promotes these three products
through its Primary Care sales group.

         As a result of recent acquisitions, the proportionate revenues derived
from Watson's branded business have increased significantly. The following
information has been restated to reflect mergers accounted for under the pooling
of interests accounting method as discussed in "Summary of Recent Transactions,"
below.

         The Company may choose to acquire additional branded products for
marketing and distribution purposes. Watson may also choose to enter into
collaborative or licensing agreements with various parties at various stages of
product development.

SUMMARY OF RECENT TRANSACTIONS

         Several strategic acquisitions have supported the Company's growth over
the past year. The Company acquired Royce Laboratories, Inc. ("Royce"), a
developer and manufacturer of off-patent pharmaceutical products; and Oclassen
Pharmaceuticals, Inc. ("Oclassen"), a developer and marketer of Dermatology
products. During 1997, Watson also entered into an agreement to acquire The
Rugby Group, Inc. ("Rugby"), a developer and marketer of

                                       2

<PAGE>

         Watson's sales of off-patent drugs have increased significantly in
recent years. The Company believes that this growth is attributable to a number
of factors, including (i) modification of certain federal and state laws to
permit or mandate substitution of off-patent drugs by pharmacists, (ii) the
enactment of abbreviated procedures for obtaining Food and Drug Administration
("FDA") approval to manufacture off-patent prescription drugs, (iii) changes in
government and third-party payor reimbursement policies to encourage cost
containment by health care providers and consumers, (iv) increased acceptance of
off-patent drugs by physicians, pharmacists and consumers, and (v) an increasing
number of products which have lost patent protection.

         During 1997, seven dosages in the hydrocodone bitartrate/acetaminophen
product group accounted for approximately 21% of total revenues. In 1996 and
1995, six dosages in the hydrocodone bitartrate/acetaminophen product group
accounted for approximately 29% and 35%, respectively, of total revenues.

BRANDED PHARMACEUTICAL PRODUCTS

         The Company markets its branded products to physicians through its four
principal sales groups: Dermatology, Women's Health, NeuroPsychiatric and
Primary Care.

         DERMATOLOGY

         Watson markets several products for the prevention and treatment of
skin diseases. These products are Monodox(R) (doxycycline monohydrate), for the
treatment of severe acne; Cordran(R) (flurandrenolide) and Cormax(TM)
(clobetasol propionate), for the treatment of dermatoses; Condylox(R) (podofilox
0.5%), for the treatment of genital warts; and Cinobac(R) (cinoxacin), for the
treatment of urinary tract infections. The Company acquired these products in
connection with its acquisition of Oclassen.

         WOMEN'S HEALTH

         The Company markets a variety of oral contraceptive products. These
products include Zovia(TM) (ethynodiol diacetate & ethinyl estradiol), Genora(R)
(norethindrone and ethinyl estradiol), Levora(R) (levonorgestrel), Nor QD(R)
(norethindrone) and Trivora(R) (levonorgestrel and ethinyl estradiol tablets,
USP - Triphasic Regimen).

         NEUROPSYCHIATRIC

         Watson markets three central nervous system products: Loxitane(R)
(loxapine succinate), for the treatment of psychotic disorders, Zarontin(R)
(ethosuximide) for the treatment of pediatric epilepsy, and Eldepryl(R)
(selegiline), a product of Somerset Pharmaceuticals, Inc. ("Somerset"). Watson
owns 50% of Somerset through a joint venture with another pharmaceutical
company. These products are sold into this growing specialty market, exclusively
to psychiatrists and neurologists.

         PRIMARY CARE

         The Company markets three products directly to primary care physicians.
These products are Norco(TM) (hydrocodone bitartrate & acetaminophen), a branded
off-patent analgesic; and Microzide(R) (hydrochlorothiazide) and Dilacor XR(R),
which are both used in the treatment of hypertension and angina. Norco(TM) and
Microzide(R) are internally developed products. Dilacor XR(R) was acquired from
RPR in 1997. The Company's Primary Care sales group was significantly expanded
in 1997 to support the promotion of this product. In 1997, sales of Dilacor
XR(R) accounted for approximately 19% of total revenues.

JOINT VENTURES

         Watson has made substantial investments in pharmaceutical joint
ventures and expects to utilize this method of investment in the future. The
Company does not control these joint ventures or the commercial exploitation of
the branded and off-patent products they develop, manufacture and/or market.
Further, there is no assurance that such joint ventures will be profitable.

                                       4
<PAGE>

         The Company owns a 50% interest in Somerset, which manufactures and
markets the product Eldepryl(R), used in the treatment of Parkinson's disease.
Somerset is actively involved in research projects regarding additional
indications of Eldepryl(R) and other chemical compounds.

         The Company owns a 50% interest in ANCIRC, a joint venture with Andrx
Corporation ("Andrx"), that is developing off-patent pharmaceutical products
utilizing the Andrx's controlled-release technology. As of March 2, 1998, ANCIRC
has two products under review with the FDA. Watson currently owns 18.5% of
Andrx, a publicly traded company that utilizes controlled-release technologies
to develop oral pharmaceutical products.

PRODUCT DEVELOPMENT

         The Company devotes significant resources to the research and
development of off-patent and proprietary products. During the three years ended
December 31, 1997, the Company incurred research and development expenditures of
$18.1 million, $22.9 million and $24.6 million, respectively. There can be no
assurance that any of the products currently in development will receive the
required regulatory approvals from the FDA.

         Watson's research and development strategy focuses on the following
product development areas: (i) the continuation of its existing oral immediate-
release products, (ii) the development of niche, difficult-to-produce off-patent
drugs, (iii) the development of sustained-release technologies and the
application of these technologies to existing products (iv) the application of
proprietary drug delivery technology for new product development in specialty
areas, and (v) medium-to-late stage new drug opportunities.

OFF-PATENT PRODUCT DEVELOPMENT

         The Company's core development efforts will remain in the area of
off-patent prescription drugs. Watson will continue to focus on niche products
that offer significant opportunity, but which may not necessarily attract
numerous competitors. The Company will also focus on technically
difficult-to-formulate products, or products that require advanced manufacturing
technology. By emphasizing the development of difficult-to-formulate products,
the Company seeks markets with limited competition, thereby creating higher
margin sales from its off-patent products. In addition, when evaluating which
drug development projects to undertake, Watson considers whether the product,
once developed, will complement other products in its portfolio, or will
otherwise assist in making the Company's product line more complete.

         The Company's acquisitions of Royce and Rugby have increased its
resources in the area of off-patent product development. The Company presently
has submissions for approval pending before the FDA representing 19 separate
products of varying dosage strengths. In addition, approximately 20 projects are
currently under development. During 1997 and through March 2, 1998, Watson
received 10 off-patent product approvals from the FDA.

         Of the 52 off-patent products currently marketed by the Company, it
received the first abbreviated new drug application ("ANDA") approval for 38
products. As of March 2, 1998, the Company believed it held the only ANDA
approval for 15 of these products.

         Over the next few years, patent protection on a relatively large number
of branded drugs will expire, thereby providing additional off-patent product
opportunities. The branded products targeted for off-patent development include
those with specialized or growing markets as well as those products with U.S.
sales of over $100 million.

         ANCIRC was formed in 1994 to conduct research and development
activities in the area of controlled-release technologies. Since its founding,
ANCIRC has conducted development on a variety of projects and has filed two
submissions with the FDA. A total of 8 products are currently under development
at ANCIRC.

                                       5
<PAGE>

PROPRIETARY PRODUCT DEVELOPMENT

         Watson is developing certain proprietary products, some of which
utilize novel drug delivery systems, that if and when developed, will require
FDA approval of a New Drug Application ("NDA") prior to marketing. The Company
is also developing proprietary products through a combination of internal and
collaborative programs, including joint ventures.

           Based on data gathered during clinical studies, the Company has
focused its efforts on two products that utilize its proprietary injection
molding drug delivery technology. The Progesterone/Vaginal Insert and
Estradiol/Vaginal Insert, which will be used for hormone replacement therapy,
are currently in Phase II/III clinical studies. There can be no assurance that
any of these proprietary products, if and when fully developed, will contribute
materially to Watson's revenues in the future.

         The Company is also involved in the development of a gum-delivery
technology and is developing two prescription pharmaceutical products in this
area. In 1994, an application was filed with the FDA for an off-patent version
of Nicorette(R), a nicotine gum product developed and marketed by Smith Kline
Beecham ("SKB"). In February 1996, SKB's Nicorette(R) was approved by the FDA as
an over-the-counter product and its exclusivity was extended to 1999.

         The Company is also developing a psoralen-based phototherapeutic
product for use in PUVA therapy for indications in psoriasis and vitiligo.
Watson believes that this product will reduce the side effects characteristic of
current psoralen therapy.

         In recent years, Somerset has increased its research and development
spending in order to 1) develop additional indications for selegiline (the
parent compound of Eldepryl(R)), using a transdermal delivery system and 2)
develop and evaluate different therapeutic areas using selegiline and other
compounds. In November 1997, Somerset announced completion of the Phase III
clinical trials of its selegiline transdermal system for the treatment of
Alzheimer's disease. Somerset reported that the preliminary analyses of the
efficacy data did not yield statistically significant differences between the
placebo and the selegiline treatment group. A Phase III clinical study using the
selegiline transdermal system in Major Depression was recently completed and is
currently undergoing evaluation. In addition, a Phase III clinical trial is
being conducted in Parkinson's disease.

SALES AND MARKETING

BRANDED PRODUCTS

         The Company markets its branded products through its four sales groups:
Dermatology, Women's Health, NeuroPsychiatric and Primary Care. Each of these
sales groups focuses on physicians who specialize in the diagnosis and treatment
of different medical conditions and each offers products to satisfy the needs of
these specialty physicians. The Company believes that this focused marketing
approach enables it to develop highly knowledgeable and dedicated sales
representatives and to foster close professional relationships with physicians.

         During 1997, the Company created or acquired the sales forces for each
therapeutic area as well as the marketing infrastructure to support sales
efforts in these specialty areas. The Company's branded products sales force has
grown to more than 300 representatives at the end of 1997. Approximately 140
sales representatives are in Primary Care, 60 are in Dermatology, 60 are in
NeuroPsychiatric, and 40 are in Women's Health. The Company's Dermatology sales
force, acquired in its merger with Oclassen, is one of the largest and best
trained in the country.

OFF-PATENT PRODUCTS

         Customer service activities are an integral part of the Company's sales
and marketing operations. The Company uses its best efforts to maintain adequate
inventories, make timely delivery of its products and provide technical and
other service support to its customers. Rugby's strong telemarketing
organization and field force are expected to enhance the Company's sales and
marketing efforts in the off-patent product area.

                                       6
<PAGE>

CUSTOMERS

         The Company markets its products primarily to pharmaceutical
wholesalers, drug distributors, and chain drug stores that in turn market to
retailers, managed care entities, hospitals and government agencies. Watson
sells its dermatology products under the "Oclassen Pharmaceuticals" label. All
of the Company's other products are marketed as products of "Watson
Laboratories". Watson has witnessed a consolidation of its customers, as chain
drug stores and wholesalers merge or consolidate. In addition, a number of the
Company's customers have instituted source programs that limit the number of
suppliers of generic pharmaceutical products carried by that customer. As a
result of these developments, there is heightened competition among off-patent
drug producers for the business of this smaller and more selective customer
base.

         The Company ships products pursuant to purchase orders. In 1997, two
customers in the aggregate accounted for 23% of the Company's product sales, 12%
and 11%, individually. In 1996, sales to one customer accounted for 10% of
product sales. In 1995, no individual customer accounted for more than 10% of
product sales.

COMPETITION

         The off-patent pharmaceutical industry is highly competitive, with
offerings from numerous off-patent manufacturers, as well as products from
off-patent divisions of major international innovator companies. Watson competes
in the marketplace by developing, acquiring or licensing pharmaceutical products
for indications that generally have relatively large patient populations or for
which limited or inadequate treatments are available. With respect to off-patent
pharmaceuticals, Watson's philosophy is to develop, acquire or license
therapeutic equivalents to previously patented products that are difficult-to-
formulate. There can be no assurance, however, that developments by others will
not render the Company's pharmaceutical products or technologies obsolete or
uncompetitive. In addition to product development, other competitive factors in
the pharmaceutical industry include product quality and price, reputation and
dissemination of technical information.

         Revenues and gross profit derived from the sales of off-patent
pharmaceutical products tend to follow a pattern based on regulatory and
competitive factors unique to the off-patent pharmaceutical industry. As patents
for brand name products and related exclusivity periods mandated by regulatory
authorities expire, the first
 off-patent manufacturer to receive regulatory approval for off-patent
equivalents of such products is generally able to achieve a relatively high
market share. As competing off-patent manufacturers receive regulatory approvals
on similar products, market share, revenues and gross profit typically decline.
Accordingly, the level of market share, revenues and gross profit attributable
to a particular off-patent product is normally related to the number of
competitors in that product's market and the timing of that product's regulatory
approval, in relation to competing approvals.

         Watson therefore is dependent, in part, on its ability to develop and
rapidly introduce new products, the timing of regulatory approval of such
products and the number and timing of regulatory approvals of competing
products. In addition to competition from other off-patent drug manufacturers,
the Company faces competition from brand name companies as they increasingly
sell their products into the off-patent market directly by establishing,
acquiring or forming licensing or business arrangements with off-patent
pharmaceutical companies. No regulatory approvals are required for a brand name
manufacturer to market their products into the off-patent market. In addition,
brand name companies are increasingly pursuing strategies to prevent or delay
the introduction of off-patent competition. These strategies include, among
other things, seeking to establish regulatory obstacles to the bioequivalence of
off-patent drugs to the brand name products and instituting legal actions based
on a host of alleged infringements.

         During 1996 and 1997, certain national drug wholesalers instituted
programs designed to provide cost savings to independent retail pharmacies on
their purchases of certain off-patent pharmaceutical products. Pursuant to the
programs, independent retail pharmacies generally agreed to purchase their
requirements of off-patent pharmaceutical products from one wholesaler and
permitted the wholesaler to select the product suppliers. Each wholesaler
encouraged off-patent drug suppliers to participate in its program by offering
to purchase the

                                       7
<PAGE>

wholesaler's requirements of particular products from a single supplier. Such
programs encouraged off-patent drug suppliers to aggressively bid to be the
exclusive supplier of products under the programs. These programs resulted in
reduced prices to non-wholesaler customers. As a result of the institution of
the programs, the off-patent drug industry experienced a significant reduction
in the prices charged by suppliers for many off-patent pharmaceutical products.

SUPPLIERS AND MATERIALS

         The principal components used in the Company's business are active and
inactive pharmaceutical ingredients and certain packaging materials. Certain
components are available only from sole-source suppliers. In addition, the FDA
must approve suppliers of certain ingredients for the Company's products. The
development and regulatory approval of Watson's products are dependent upon its
ability to procure active ingredients and packaging materials from FDA-approved
sources. FDA approval of a new supplier would be required if, for example,
active ingredients or such packaging materials were no longer available from the
initially approved source. The qualification of a new supplier could potentially
delay the manufacture of the drug involved. Arrangements with foreign suppliers
are subject to certain additional risks, including the availability of
governmental clearances, export duties, political instability, currency
fluctuations and restrictions on the transfer of funds.

         Although Watson considers its sources of supply to be adequate and, to
date, no significant difficulty has been encountered in obtaining materials
required for products, there can be no assurance that the Company will continue
to be able to obtain materials as required or at reasonable prices. An extended
inability to obtain material or significant price increases that cannot be
passed on to customers could have a material adverse effect on the Company.

         Watson contracts for the manufacture of certain products and intends to
evaluate this strategy for certain future products. Outside contract
manufacturing enables the Company to direct its financial resources to product
in-licensing and acquisition, product development and sales and marketing
efforts. The selected outside manufacturers are required by the Federal Food,
Drug and Cosmetic Act and by FDA regulations to follow current Good
Manufacturing Practices ("cGMP"). Accordingly, the Company is dependent upon its
contract manufacturers to comply with such requirements or similar standards
imposed by foreign regulators. To ensure such compliance, quality assurance
audits of the contract manufacturers sites and batch records are performed to
determine compliance with cGMP requirements and to the Company's specifications.
In addition, the FDA conducts regular inspections and audits of firms subject to
cGMP requirements. Watson believes it has good relationships with its outside
contract manufacturers.

         From time to time, certain outside suppliers have experienced
regulatory difficulties that have inhibited their ability to deliver products to
the Company. In the event a supplier has such a difficulty which cannot be
resolved within a reasonable time, the resulting delay could have a material
adverse effect on the Company.

PRODUCT LIABILITY

         Product liability suits by consumers represent a continuing risk to
firms in the pharmaceutical industry. One method Watson employs to minimize such
risks is to enforce stringent quality control procedures. Although the Company
carries product liability insurance, it believes that no reasonable amount of
insurance can fully protect against all such risks due to the inherent risks
associated with the production of pharmaceuticals for human consumption.

PATENTS AND PROPRIETARY RIGHTS

         Watson believes that protection of its patents, proprietary products,
technologies, processes and know-how is important to its business. The Company
maintains an active patent program to protect its technologies. To date, 15 U.S.
patents have been issued to the Company: five covering compositions of matter
for its oral delivery systems (which patents expire in 2003), five covering
aspects of its buccal systems (which expire between 2005 and 2010), two covering
aspects of its mucosal tissue drug delivery (which expire in 2007 and 2008), one
covering its microencapsulation composition used in its sustained release oral
potassium chloride product (expiring in 2006), one covering its chlorhexidine
compound (expiring in 2007) and one covering its cutaneous therapeutic devices

                                       8
<PAGE>

(expiring in 2009). The Company maintains an aggressive patent program, has
three additional United States patents pending and has several patent
applications at different stages of development. Recent changes to the patent
law resulting from passage of the Uruguay Round Agreements Act ("URAA") will
lengthen the term of some granted patents. Generally, patents have terms that
are the longer of 17 years from patent grant or 20 years from patent
application. The Company also seeks patent protection in major foreign
pharmaceutical markets, and has numerous foreign patents and patents pending.

         There can be no assurance that Watson's patents or those of its
competitors would be held valid by a court of competent jurisdiction. There can
be no assurance that pending patents will result in issued patents, that patents
issued to or licensed by the Company will not be challenged or circumvented by
competitors, or that such patents will be found to be valid or sufficiently
broad to protect the Company's technology or to provide the Company with a
competitive advantage. Watson relies on non-disclosure agreements with certain
employees, consultants and other parties to protect, in part, trade secrets and
other proprietary technology. There can be no assurance that these agreements
will not be breached, that the Company will have adequate remedies for any
breach, or that others will not independently develop equivalent proprietary
information or that third-parties will not otherwise gain access to the
Company's trade secrets and proprietary knowledge.

         Watson may find it necessary to initiate litigation to enforce its
patent rights, to protect its trade secrets or know-how and to determine the
scope and validity of the proprietary rights of others. Patent litigation can be
costly and time-consuming, and there can be no assurance that the Company's
litigation expenses will not be significant in the future or that the outcome of
such litigation will be favorable to the Company.

GOVERNMENT REGULATION

         All pharmaceutical manufacturers are subject to extensive regulation by
the federal government, principally the FDA and, to a lesser extent, by state
and local governments. The Federal Food, Drug and Cosmetic Act and other federal
statutes and regulations govern or influence the testing, manufacture, safety,
labeling, storage, recordkeeping, approval, advertising, promotion, sale and
distribution of pharmaceutical products. Noncompliance with applicable
requirements can result in fines, recall or seizure of products, total or
partial suspension of production and/or distribution, refusal of the government
to enter into supply contracts or to approve NDAs or ANDAs, and criminal
prosecution. The FDA also has the authority to revoke previously granted drug
approvals.

         Changes in FDA procedures have increased the time and expense involved
in obtaining NDA and ANDA approvals and in complying with the FDA's cGMP
standards. The ANDA drug development and approval process now averages
approximately two to five years. FDA approval is required before each dosage
form of any new drug can be marketed. Applications for FDA approval must contain
information relating to bioequivalency, product formulation, raw material
suppliers, stability, manufacturing processes, packaging, labeling and quality
control. FDA procedures require full-scale manufacturing equipment to be used to
produce test batches for FDA approval. Validation of manufacturing processes by
the FDA also is required before a Company can market new products. The FDA
conducts pre-approval and post-approval reviews and plant inspections to enforce
these rules. Supplemental filings are required for approval to transfer products
from one manufacturing site to another and may be under review for a year or
more. In addition, certain products may only be approved for transfer once new
bioequivalency studies are conducted.

         The Company's manufacturing operations are required to comply with cGMP
standards as interpreted by the FDA. This concept encompasses all aspects of the
production process, including validation and record keeping, and involves
changing and evolving standards. In recent years, the FDA has increased the
number of regular inspections to determine compliance with its cGMP standards.
The evolving and complex nature of regulatory requirements, the broad authority
and discretion of the FDA and the generally high level of regulatory oversight
results in a continuing possibility that from time to time the Company will be
adversely affected by regulatory actions despite its ongoing efforts and
commitment to achieve and maintain full compliance with all regulatory
requirements.

                                       9
<PAGE>

         The Hatch-Waxman Act of 1984 extended the established abbreviated
application procedure for obtaining FDA approval for off-patent forms of
brand-name drugs originally marketed before 1962 which are off-patent or whose
market exclusivity has expired. This act also provides market exclusivity
provisions that could preclude the submission or delay the approval of a
competing ANDA. One such provision allows a five-year market exclusivity period
for NDAs involving new chemical compounds and a three-year market exclusivity
period for NDAs (including different dosage forms) containing new clinical
investigations essential to the approval of the application. The market
exclusivity provisions apply equally to patented and non-patented products.
Another provision may extend patents for up to five years as compensation for
reduction of the effective life of the patent as a result of time spent by the
FDA reviewing a drug application. Patents may also be extended pursuant to the
terms of the URAA.

         The Generic Drug Enforcement Act of 1992 establishes penalties for
wrongdoing in connection with the development or submission of an ANDA by
authorizing the FDA to permanently or temporarily debar companies or individuals
from submitting or assisting in the submission of an ANDA, and to temporarily
deny approval and suspend applications to market off-patent drugs. The FDA may
also suspend the distribution of all drugs approved or developed in connection
with certain wrongful conduct and/or withdraw approval of an ANDA and seek civil
penalties. The FDA can also significantly delay the approval of any pending ANDA
under the Fraud, Untrue Statements of Material Facts, Bribery and Illegal
Gratuities Policy Act.

         Medicaid, Medicare and other reimbursement legislation or programs
govern reimbursement levels, including requiring that all pharmaceutical
manufacturers rebate to individual states a percentage of their revenues arising
from Medicaid-reimbursed drug sales. The required rebate for off-patent drug
manufacturers is currently 11% of average net sales price for products marketed
under ANDAs. For products marketed under NDAs, manufacturers are required to
rebate the greater of 15.1% of average net sales price or, the difference
between average net sales price and the lowest net sales price during a
specified period. The Company believes that the federal and/or state governments
may continue to enact measures in the future aimed at reducing the cost of drugs
to the public. The Company cannot predict the nature of such measures or their
impact on the Company's profitability.

         Federal, state and local laws of general applicability, such as laws
regulating working conditions also govern Watson. In addition, the Company is
subject, as are all manufacturers generally, to various federal, state and local
environmental protection laws and regulations, including those governing the
discharge of material into the environment. Compliance with such environmental
provisions is not expected to have a material effect on the earnings, cash
requirements or competitive position of the Company in the foreseeable future.
However, no assurance can be given that changes to, or compliance with, such
environmental provisions will not have a material effect on the Company's
earnings, cash requirements or competitive position.

         Continuing studies of the proper utilization, safety, and efficacy of
pharmaceuticals and other health care products are being conducted by industry,
government agencies and others. Such studies, which increasingly employ
sophisticated methods and techniques, can call into question the utilization,
safety and efficacy of previously marketed products and in some cases have
resulted, and may in the future result, in the discontinuance of their
marketing. In certain countries, these studies gave rise to claims for damages
from persons who believe they have been injured through the use of particular
pharmaceutical products.

SEASONALITY

         The Company's business, taken as a whole, is not materially affected by
seasonal factors.

PERSONNEL

         As of December 31, 1997, the Company had 1,020 full-time employees,
including 15 employees who hold Ph.D.'s. Of the Company's employees, 96 are
engaged in research and development, 358 in manufacturing, 165 in quality
assurance and quality control, 323 in sales and marketing, and 78 in
administration. Employees are not represented by unions and the Company has
never experienced a work stoppage.

CAUTIONARY STATEMENT FOR PURPOSES OF THE SAFE HARBOR PROVISIONS OF THE PRIVATE
SECURITIES LITIGATION REFORM ACT OF 1995

         This report contains forward-looking statements. The Company desires to
take advantage of the safe harbor provisions of the Private Securities
Litigation Reform Act of 1995 and is including this statement for the express
purpose of availing itself of the protections of the safe harbor with respect to
all forward-looking statements. Several important factors, in addition to the
specific factors discussed in connection with such forward-looking statements
individually, could affect the future results of the Company and could cause
those results to differ materially from those expressed in the forward-looking
statements contained herein.

         Such additional factors include, among other things, future economic,
competitive and regulatory conditions, demographic trends, financial market
conditions, the management of acquisitions and future business decisions of the
Company and its competitors, all of which are difficult or impossible to predict
accurately and many of which are beyond the control of the Company. Therefore,
the Company wishes to caution each reader of this report to consider carefully
these factors as well as the specific factors discussed with each
forward-looking statement in this report and as disclosed in the Company's
filings with the Securities and Exchange Commission as such factors, in some
cases, have affected, and in the future (together with other factors) could
affect, the ability of the Company to implement its business strategy and may
cause actual results to differ materially from those contemplated by the
statements expressed herein.

ITEM 2.  PROPERTIES

         The Company's headquarters are located in Corona, California and Watson
owns the related land and buildings. The Company maintains manufacturing
facilities in Corona, California, Miami, Florida, Copiague, New York and Dayton,
Ohio. The principal manufacturing site in Corona, California as well as the
facilities in Copiague, New York and Dayton, Ohio are owned. The Company leases
another manufacturing facility in Corona, California, as well as research and
development and manufacturing facilities in Miami, Florida. Watson's principal
research facilities are located in Corona, California and are owned by the
Company.

         The facilities leased from third parties are subject to leases with
terms expiring, subject to renewal options, between 1998 and 2002 and with
current monthly base rental payments ranging from approximately $2,000 to
approximately $25,000. One property in Corona, California is leased from a trust
that includes the Company's Chairman and its Executive Vice President - Research
and Development. This lease expires, subject to renewal options, in 2000 and
provides for monthly base rental payments of $25,000. Some of the Company's
leases contain escalation provisions and require the Company to pay for
utilities, taxes, insurance and maintenance expenses.

         Although the Company's facilities are adequate to meet its current
needs, Watson has plans to construct and acquire additional space to accommodate
its growth. In keeping with this strategy, the Company completed in 1996
construction of 100,000 square feet of additional manufacturing workspace in its
Corona, California location. During 1997, the Company continued construction of
a 90,000-square-foot manufacturing plant in Changzhou City, People's Republic of
China. This facility is expected to become operational in 1998. Recently,
construction began on 40,000 square feet of additional space for administrative
and research-related activities at Watson's headquarters location.

ITEM 3.  LEGAL PROCEEDINGS

         In October 1995, a class action complaint captioned JIMMY JACKSON V.
CIRCA PHARMACEUTICALS, INC., ET al., was filed against Circa, Lawrence Raisfeld
and Robert Shulman, former presidents of Circa, and Roger Jordan, president of
Vitarine Pharmaceuticals ("Vitarine") in the Circuit Court of Tallapoosa County,
Alabama. This suit is expected to settle for $225,000.

         In November 1997, a suit was filed against Royce and Watson naming them
as defendants, along with five other corporations, in an action captioned
MICHAEL D. HARDY, INDIVIDUALLY AND MICHAEL D. HARDY AS EXECUTOR OF THE ESTATE OF
JUDITH MARIE HARDY V. ROYCE LABORATORIES, INC., ET AL. in the Western District
of Kentucky at Louisville. Plaintiff alleges that his wife suffered personal
injuries due to her ingestion of the drug quinine for leg cramps in June 1995,
and personal injuries leading to death due to its ingestion in April 1997. The
plaintiff seeks actual damages in the amount of six million dollars for personal
injuries suffered by his wife, actual damages in the amount of ten million
dollars for wrongful death and additional punitive damages. The parties to this
action are presently conducting discovery. It is contemplated that any liability
and defense costs will be covered by the Company's product liability insurance.
Watson and Royce intend to vigorously defend this action.

         The Company is involved in various other disputes and litigation
matters that arise in the ordinary course of business. The litigation process is
inherently uncertain and it is possible that the resolution of these disputes
and lawsuits may adversely affect the Company. In management's opinion, Watson
is not currently involved in any legal proceedings which, individually or in the
aggregate, could have a material effect on its consolidated financial condition,
operations or cash flows.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

(1)      The Company merged with Circa Pharmaceuticals, Inc. ("Circa"), in July
         1995, with Oclassen Pharmaceuticals, Inc. ("Oclassen"), in February
         1997, and with Royce Laboratories, Inc. ("Royce"), in April 1997. These
         transactions were accounted for as pooling of interests, and
         consequently, the consolidated financial data presented include those
         of Circa, Oclassen, and Royce for all periods presented. The costs
         associated with these mergers were $13.9 million in 1995 and $14.7
         million in 1997.

         In October 1997, the Company effected a two-for-one stock split in the
         form of a 100% stock dividend. Share and per share amounts for all
         reported periods have been restated to reflect the stock split.

(2)      Included in investment and other income for the years ended December
         31, 1995, 1994, and 1993 were gains from the sale of common stock of
         Marsam Pharmaceuticals, Inc. ("Marsam") of $6.2 million, $3.2 million,
         and $14.5 million, respectively. The Company has no remaining
         investment in Marsam.

(3)      The gain from (provision for) legal settlement was the result of
         lawsuits in which Circa was a defendant. All of these lawsuits were
         settled by the first quarter of 1996.

(4)      As a result of the pooling of interest accounting for the Company's
         1995 merger with Circa, an income tax benefit of $29.8 million was
         recorded for the year 1993. This tax benefit resulted from a reduction
         in the valuation allowance for Circa's net deferred tax assets. These
         net deferred tax assets represented net operating loss and tax credit
         carryforwards generated by Circa prior to its merger with the Company.

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

         Except for the historical information contained herein, the following
discussion contains forward-looking statements that involve risks and
uncertainties. Such risks and uncertainties are discussed below in "Factors That
May Affect Future Results."

GENERAL

         The Company derives its revenues from the development, manufacture and
sale of pharmaceutical products. From the Company's founding in 1983 until
mid-1995, revenues were generated primarily from sales of off-patent versions of
branded pharmaceutical products. In order to create a more predictable and
diverse revenue stream, Watson has recently made significant investments in
branded pharmaceutical businesses and products. As compared with off-patent
products, branded products offer stronger competitive protection and typically
sell at higher and more stable margins.

         As the Company diversifies its product portfolio, off-patent products
remain an integral component of the Company's current and future revenues. In
recent years, the Company has expanded its product offering through internal
development and acquisitions. Watson will continue to invest significant
resources in the development of difficult-to-produce, niche products for its
off-patent business.

BRANDED PHARMACEUTICALS

         In 1997, a strategy was developed to target three specialty therapeutic
areas: Women's Health, Dermatology and NeuroPsychiatric. The Company invested
significant resources in the acquisition and development of products and
personnel for these focus areas. Specialty sales groups were either created or
acquired to successfully promote newly purchased products. Watson's total sales
force grew from approximately 20 representatives in late 1996 to more than 300
by the end of 1997. Acting as the cornerstone in the sales infrastructure is the
Primary Care sales division. This group provides key support for Watson's pain
and hypertension products and also provides a direct link to the Primary Care
physician for products promoted by the specialty sales groups.

                                       15
<PAGE>

         Also in 1997, Watson secured its revenue stream from Dilacor XR(R)
(diltiazem hydrochloride) by purchasing the rights to this branded product. This
transaction provided Watson full control over the marketing and distribution of
Dilacor XR(R) and any off-patent versions to be offered by the Company. Prior to
this acquisition, the Company owned a royalty interest in the product.

         ACQUISITION OF PRODUCT RIGHTS TO DILACOR XR(R) - On June 30, 1997, the
Company obtained the exclusive U.S. and certain worldwide marketing, sales, and
distribution rights to Dilacor XR(R) for $190.0 million in cash, future
royalties, and an inventory supply agreement. The Company's Primary Care sales
group promotes Dilacor XR(R).

         This product has been available in the U.S. for the treatment of
hypertension since June 1992 and was approved for the treatment of chronic
stable angina in March 1995. In October 1997, Andrx Corporation received
regulatory approval and began to market an off-patent form of Dilacor XR(R). In
response, the Company has introduced its own off-patent alternative, which was
well received in the market. Due to this recent off-patent competition, the
Company's product sales and gross profits from Dilacor XR(R) are likely to
decline in future periods.

         ACQUISITION OF PRODUCTS FROM G. D. SEARLE & CO. ("SEARLE") - In the
fourth quarter of 1997, the Company acquired the U.S. rights to certain Searle
branded off-patent oral contraceptive products. The Food and Drug Administration
("FDA") approved one of these products, Trivora(R) (levonorgestrel and ethinyl
estradiol), in February 1998. Under the terms of this agreement, cash of $85.0
million was paid through December 31, 1997, which included $5.0 million for
Trivora(R). The Company will pay a total of $45.0 million for Trivora(R), with
the remaining $40.0 million to be paid in 1998. The Company also acquired the
U.S. rights to additional oral contraceptive products from Searle (the "Future
Products"). Payment for these products is due upon achievement of certain
events, which include in certain instances, approvals by the FDA. If all
contingent events occur before July 1, 1999, the aggregate acquisition cost for
the Future Products will be $48.5 million plus certain contingent payments. The
Searle products complement Watson's existing oral contraceptive line and are
sold through the Company's Women's Health division.

         ACQUISITION OF OCLASSEN PHARMACEUTICALS, INC. ("OCLASSEN") - In
February 1997, the Company acquired Oclassen. Watson issued approximately 6.6
million shares of its common stock for all of the outstanding common shares of
Oclassen. At the acquisition date, the value of the Watson shares issued was
$135.0 million. Oclassen markets specialty pharmaceutical products to prevent
and treat skin diseases. Currently, the following five products are marketed:
Monodox(R) (doxycycline monohydrate), Condylox(R) (podofilox 0.5%), Cordran(R)
(flurandrenolide), Cinobac(R) (cinoxacin) and Cormax(TM) (clobetasol
propionate). The Company's Dermatology sales group promotes the Oclassen
products.

         ACQUISITION OF PRODUCTS FROM COCENSYS, INC. ("COCENSYS") - In October
1997, the Company acquired two products and two co-promotion agreements from
CoCensys. In addition, Watson hired certain sales and marketing personnel from
CoCensys. A total of $9.0 million was paid. The products purchased from CoCensys
are sold through the NeuroPsychiatric sales group and are expected to serve the
needs of a growing specialty market for the treatment of psychiatric disorders,
epilepsy, schizophrenia and pain.

OFF-PATENT PHARMACEUTICALS

         During 1997 and through early 1998, Watson increased its off-patent
product offerings through acquisitions and internal development.

         ACQUISITION OF ROYCE LABORATORIES, INC. ("ROYCE") - In April 1997, the
Company acquired Royce. Royce develops and manufactures off-patent prescription
drugs in solid dosage forms (tablets and capsules). The Royce product portfolio
and development pipeline complemented the Company's business, with little
overlap. The Company issued approximately 5.2 million shares of its common stock
(valued at $98 million on the merger date) for all of the outstanding common
shares of Royce. All Royce products are now marketed directly by the Company
under the "Watson Laboratories" label.

                                       16
<PAGE>

         1998 PURCHASE OF THE RUGBY GROUP, INC. ("RUGBY") - On February 27,
1998, Watson completed its acquisition of Rugby from Hoechst Marion Roussel,
Inc. Rugby develops, manufactures, and markets a wide array of off-patent
pharmaceutical products. The agreement provided for an initial payment of
approximately $67.5 million in cash and contingent payments based on certain
future sales and operating results.

         INTERNAL PRODUCT DEVELOPMENT - In 1997, Watson received Food and Drug
Administration ("FDA") approval for 10 off-patent products in 23 separate dosage
strengths.

OTHER SIGNIFICANT INVESTMENTS AND JOINT VENTURES

         1995 ACQUISITION OF CIRCA - In July 1995, the Company merged with Circa
in a pooling of interests transaction. Circa manufactured off-patent
pharmaceuticals and held investments in Somerset Pharmaceuticals, Inc.
("Somerset"), Andrx Corporation ("Andrx"), and the ANCIRC joint venture with
Andrx. The Company issued approximately 37.4 million shares of its common stock
for all of the outstanding common shares of Circa. On the merger date, the value
of this acquisition was approximately $680 million.

         PREVIOUS ROYALTY AGREEMENT - Prior to the Company's June 1997 purchase
of the rights to Dilacor XR(R) from Rhone-Poulenc Rorer, Inc. ("RPR"), Circa and
RPR were partners in the development of this product. Since 1993, the Company
has earned royalties from RPR's sales of Dilacor XR(R). Revenues earned under
this royalty arrangement were $14.2 million in 1997 (earned through the
termination date of June 30, 1997), $27.2 million in 1996 and $22.2 million in
1995.

         SOMERSET JOINT VENTURE - The Company owns 50% of the outstanding shares
of Somerset, which markets the product Eldepryl(R) for the treatment of
Parkinson's disease. Somerset is also developing additional indications for
selegiline (the parent compound of Eldepryl(R)), using a transdermal delivery
system. The Company recorded equity in earnings from this joint venture of $12.7
million in 1997, $20.1 million in 1996, and $24.8 million in 1995. Orphan drug
exclusivity expired for Eldepryl(R) in June 1996. During 1997 and 1996, a number
of competitors introduced off-patent tablets to compete with Eldepryl(R)
capsules. The introduction of off-patent competition and increased research and
development spending in support of various clinical trials has significantly
reduced Somerset's contribution to the Company's operating results. Management
expects the Company's earnings from Somerset to continue to decline from current
levels.

         INVESTMENT IN ANDRX - In 1994, the Company acquired a 7.5% interest in
Andrx, a drug delivery company utilizing controlled-released technologies to
develop oral pharmaceutical products. Watson increased its ownership interest in
Andrx in October 1995 and again in June 1997. At December 31, 1997, the Company
owned approximately 18.5% of the outstanding shares of Andrx. Following Andrx'
initial public offering in June 1996 (Nasdaq: ADRX), the fair value of this
investment has increased by $55.2 million to $92.2 million at December 31, 1997.

         ANCIRC JOINT VENTURE - In 1994, the Company and Andrx formed a joint
venture, ANCIRC, to develop off-patent pharmaceutical products utilizing Andrx'
controlled-release technology. During 1995, Watson increased its ownership
interest in this joint venture from 40% to 50%. The Company utilizes the equity
method to account for this joint venture and recognized losses from ANCIRC of
approximately $2.0 million, $2.0 million and $1.7 million in 1997, 1996 and
1995, respectively. To date, ANCIRC has filed two abbreviated new drug
applications ("ANDA") with the FDA.

QUARTERLY FLUCTUATIONS

         The Company's results of operations on a quarterly basis have
fluctuated in the past, and may continue to fluctuate. The Company believes such
fluctuations are primarily due to new product introductions and to a variety of
additional factors including, but not limited to, purchasing practices of the
Company's customers and changes in the degree of competition regarding the
Company's products.

YEARS ENDED DECEMBER 31, 1997 AND 1996

         Revenues for the year ended December 31, 1997 were $338.3 million
compared to $250.8 million for the year ended December 31, 1996, an increase of
$87.5 million or 34.9%. The increase in revenues was composed of a $100.4
million increase in product sales, partially offset by a $12.9 million decrease
in royalty income. The increase in product sales was largely due to sales of
Dilacor XR(R), which was purchased from RPR in June 1997. The Company also
experienced 1997 sales increases in Dermatological products, Women's Health
products, core off-patent products and new products approved or acquired during
the year. These sales increases were partially offset by decreased sales of
certain strengths in the Company's hydrocodone product line.

                                       18
<PAGE>

         Royalty income decreased $12.9 million or 47.5% in 1997 as compared
with 1996 due to the Company's purchase of the Dilacor XR(R)product line from
RPR in June 1997.

         Gross profit margins increased to 61.4% in 1997 from 54.4% in 1996. The
increase in the gross profit margin was due largely to sales of Dilacor XR(R),
higher sales of Dermatological branded products and sales of new products
introduced in 1997. The increased gross profit margin from these products was
partially offset by a decline in gross profit margins of certain core off-patent
products.

         Research and development expenses decreased from $22.9 million in 1996
to $18.1 million in 1997. Following the mergers with Royce and Oclassen, the
Company consolidated certain research and development functions and eliminated
duplicate programs.

         Selling, general and administrative expenses increased from $38.9
million in 1996 to $50.9 million in 1997. The increase consists of a $16.8
million increase in sales and marketing expenses and a $4.8 million decrease in
general and administrative costs. The Company incurred increased sales and
marketing costs as it expanded its branded products sales and marketing efforts.
The Company increased its sales force from approximately 20 representatives in
late 1996 to more than 300 at December 31, 1997.

         As a result of the mergers of Royce and Oclassen with Watson, and the
subsequent consolidation of many of the administrative functions, the Company
has experienced a decrease in its general and administrative expenses. As a
percentage of revenues, general and administrative costs decreased from 7.4% to
4.0% from 1996 to 1997, respectively. This decrease reflects efficiencies
achieved following the mergers and the fact that the Company's revenue growth
outpaced the growth in administrative costs.

         Amortization expense in 1997 increased from $386,000 to $7.2 million
due to the amortization associated with product rights acquired during the year.
Amortization expense in 1997 was primarily due to the purchase of Dilacor XR(R).
The Company has capitalized these product rights and is amortizing them over the
estimated 17-year life of the product.

         In 1997, the Company recorded one-time charges of $14.7 million for
costs incurred in connection with the mergers of Royce and Oclassen. These costs
included investment banking fees and other merger-related expenses. No such
expenses were incurred in 1996.

         Equity in earnings from joint ventures decreased $7.2 million or 40.2%
to $10.7 million in 1997 compared to $17.9 million in 1996, due primarily to
lower earnings from Somerset. The decrease in Somerset earnings is due in part
to the loss of exclusivity for Eldepryl(R) in June 1996. During 1997 and 1996, a
number of competitors introduced off-patent tablets to compete with Eldepryl(R)
capsules. Increased competition and research and development spending in support
of various clinical trials have significantly reduced Somerset's contribution to
the Company's operating results. Management expects the Company's earnings from
Somerset to continue to decline.

         Investment and other income increased 17.2% to $11.6 million in 1997
from $9.9 million in 1996 due to higher average cash and marketable securities
balances in 1997.

         The provision for income taxes increased to $54.4 million in 1997,
compared to $35.9 million in 1996. The effective income tax rate was 38.0% and
31.0% for the years ended December 31, 1997 and 1996, respectively. The increase
in the Company's effective income tax rate was due primarily to the
non-deductibility of a significant portion of merger expenses incurred in 1997
and lower earnings from Somerset which are partially exempt from tax.

         Net income increased to $90.2 million in 1997 from $78.6 million in
1996. As a percentage of revenues, net income decreased to 26.7% in 1997 from
31.3% in 1996 principally due to certain non-recurring merger expenses related
to the mergers with Royce and Oclassen and the higher effective tax rate in
1997. Exclusive of merger expenses of $14.7 million and related income taxes,
net income for 1997 would have been $103.1 million (or $1.15) per share, an
increase of 31.3% over 1996.

YEARS ENDED DECEMBER 31, 1996 AND 1995

         Revenues for the year ended December 31, 1996 were $250.8 million
compared to $192.5 million for the year ended December 31, 1995, an increase of
$58.3 million or 30.3%. The increase in revenues was composed of a $53.4 million
increase in product sales and a $4.9 million increase in royalty income. The
increase in product sales was due to: (i) sales of products introduced in 1996
which totaled $26.1 million; (ii) a $24.9 million increase in sales relating to
products introduced during the fourth quarter of fiscal 1995 and; (iii) a net
increase in sales of the Company's other core products, defined generally as
products available in the market place for at least twelve months. These
increases were partially offset by decreased sales of certain strengths of
hydrocodone products.

         Royalty income increased 22.1% in 1996 as compared with 1995 due to
increased demand for Dilacor XR(R). In June 1997, Watson purchased the product
rights to Dilacor XR(R).

         Gross profit margins increased to 54.4% in 1996 from 52.2% in 1995.
This favorable increase was due to higher than average gross margins earned on
the sales of certain core products and new products introduced during 1996.

         Research and development expenses decreased slightly from $24.6 million
in 1995 to $22.9 million in 1996. Following the merger with Circa, the Company
integrated the two research and development departments of Watson and Circa into
one, eliminating duplicate programs.

         Selling, general and administrative expenses increased from $35.2
million in 1995 to $39.3 million in 1996. As a percentage of revenues, these
costs decreased from 18.3% to 15.7% from 1995 to 1996, respectively, which
reflects management's cost control efforts and the fact that the Company's
revenue growth outpaced the growth in selling, general and administrative
expenses.

         In connection with the merger with Circa, the Company recorded a
one-time $13.9 million merger-related charge. This charge included investment
banking fees and other costs related to the consolidation of operations of the
two companies. No such expenses were incurred in 1996.

         Equity in earnings from joint ventures decreased $4.9 million or 21.3%
to $17.9 million in 1996 compared to $22.8 million in 1995. These earnings
primarily represent earnings from Somerset and ANCIRC. Equity in earnings from
Somerset decreased from $24.8 million in 1995 to $20.1 million in 1996 in part
due to: (i) the loss of exclusivity for Eldepryl(R) in June 1996 and, (ii)
increased research and development expenditures in support of the Phase III
clinical trials. During 1996, three competitors introduced off-patent tablets to
compete with Eldepryl(R) capsules. The Company's portion of ANCIRC's losses
increased slightly from $1.7 million in 1995 to $2.0 million in 1996.

         Investment and other income decreased $3.0 million or 23.6% to $9.9
million in 1996 from $12.9 million in 1995. This decrease was due to the 1995
recognition of a $6.2 million gain from the sale of Marsam Pharmaceuticals, Inc.
common stock, a stock held for investment purposes. This was partially offset by
an increase in interest income in 1996 which resulted from higher short-term
interest rates on a larger base of invested cash.

         The provision for income taxes increased to $35.9 million in 1996,
compared to $24.9 million in 1995. The effective income tax rates were 31.0% and
34.0% for the years ended December 31, 1996 and 1995, respectively. The higher
effective income tax rate in 1995 resulted primarily from the non-deductibility
of a significant portion of merger expenses incurred in that year.

         Net income increased to $78.6 million in 1996 from $48.2 million in
1995. As a percentage of revenues, net income increased to 31.3% in 1996 from
25.0% in 1995 principally due to: (i) revenue growth and continued cost control
efforts during 1996 and, (ii) the one-time merger expenses related to the merger
with Circa in 1995.

LIQUIDITY AND CAPITAL RESOURCES

         The Company's working capital decreased from $292.9 million at December
31, 1996 to $146.9 million at December 31, 1997. This $146.0 million decrease
was primarily due to the product right acquisitions of Dilacor XR(R) ($140.0
million), and Women's Health products from Searle ($85.0 million), and the
increased investment in Andrx ($15.3 million). The overall decrease was
partially offset by 1997 cash flow from operations ($97.0 million).

         The Company invested $14.6 million in capital expenditures during 1997.
This investment consisted of land, leasehold and building improvement additions
of $7.2 million and machinery, research and lab equipment additions of $7.4
million. Watson expects to invest approximately $25.0 million in capital
improvements in 1998.

         At December 31, 1997, the Company had notes payable outstanding of
approximately $3.2 million. These notes are unsecured, include interest at fixed
rates ranging from 8.1% to 13.5% per annum and require monthly payments ranging
from $94,000 in 1998 to $78,000 through August 2001. In addition, two credit
facilities are available to the Company with unsecured borrowing commitments
totaling $95.0 million. Watson has made no borrowings against these credit
facilities as of December 31, 1997.

         The Company's purchase of the rights to Dilacor XR(R) was structured
with a $40.0 million cash payment in June 1997 and a $55.0 million payment in
July 1997. At December 31, 1997, the remaining scheduled payments are due as
follows:

                    DUE DATE                   AMOUNT
                    --------              -------------
                    January 1, 1998       $45.0 million
                    January 1, 1999        30.0 million
                    January 1, 2000        15.0 million
                    January 1, 2001         5.0 million
                                          -------------
                        Total             $95.0 million
                                          =============

         The Company's cash and marketable securities totaled $114.9 million at
December 31, 1997. Management believes that the Company's cash and marketable
securities, plus cash provided from operations will be sufficient to meet its
normal operating requirements during the coming year. However, the Company has
entered into certain acquisitions that are expected to require significant
future cash payments. To date, the Company has used existing cash to fund its
acquisitions, including approximately $67.5 million paid in February 1998
pursuant to the Rugby acquisition. However, Watson may require the use of its
existing credit facilities or additional funding in order to meet its remaining
acquisition commitments. At the present time, the Company is pursuing financing
alternatives, which include modifications of its current credit facilities, a
public or private debt offering or some combination of these alternatives.
Management expects to complete acceptable financing arrangements in the near
future.

         The Company continues to review additional opportunities to acquire or
invest in companies, technologies, product rights and other investments that are
compatible with its existing business. Watson could use sources other than cash,
such as financing alternatives discussed herein, to fund additional acquisitions
or investments. If such acquisition or investment is completed, the Company's
operating results and financial condition could change materially in future
periods.

         Management believes inflation does not have, and has not had, a
significant impact on the Company's revenues or operations.


ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         Substantially all of the Company's liquid investments are at fixed
interest rates and therefore the fair value of these instruments is affected by
changes in market interest rates. However, all of the Company's liquid
investments mature within one year. As a result, the Company believes that the
market risk arising from its holding of these financial instruments is minimal.

                                       21
<PAGE>

         The Company's investment in Andrx, which was stated at a fair value of
$92.2 million at December 31, 1997, is composed of 2.7 million shares of Andrx
common stock. Andrx common stock has traded on The Nasdaq Stock Market, under
the symbol "ADRX", since its initial public offering in June 1996. As a publicly
traded equity security, this investment has exposure to price risk. The
following table sets forth the Andrx quarterly high and low share price
information from its initial public offering through December 31, 1997:

                                        HIGH           LOW

FACTORS THAT MAY AFFECT FUTURE RESULTS

         The Securities and Exchange Commission ("SEC") encourages companies to
disclose forward-looking information so investors may better understand a
company's future prospects and make informed investment decisions. This report
contains such forward-looking statements made pursuant to the safe harbor
provisions of the Securities Litigation Reform Act of 1995. The reader must
carefully consider all such statements as they inherently involve certain risks
and uncertainties that could cause actual results to differ materially from the
Company's forward-looking statements. The reader should carefully evaluate such
statements in light of risk factors described herein or in the Company's other
SEC filings.

         The Company's future results of operations will depend, to a
significant extent, upon its ability to introduce new off-patent and branded
pharmaceutical products. Future operating results may vary significantly on an
annual or quarterly basis depending on the timing of, and the Company's ability
to obtain, FDA approvals for such products and FDA approvals for shipment of
such products. Newly introduced off-patent products with limited or no
off-patent competition are typically sold at higher prices, often resulting in
increased gross profit margins. As competition from other manufacturers
intensifies, selling prices typically decline. The Company's future operating
results may also be affected by a variety of additional factors, including
customer purchasing practices and changes in the degree of competition affecting
the Company's products. Introduction by other companies of competitive products
could have a material adverse effect on the operating results and financial
condition of the Company.

         The Company has been involved in a number of significant merger and
acquisition transactions. These transactions have been motivated by many
factors, including the desire to expand and diversify the Company's product
portfolio, the desire to obtain new technologies and the desire to attract key
personnel. Growth through acquisition presents significant risks, including
those associated with the ability to integrate and successfully operate acquired
businesses, the ability to develop and implement operational and financial
systems to manage rapidly growing operations, the substantial management time
devoted to such activities, the possibility of undisclosed liabilities, risks
related to product transition and the ability to realize anticipated benefits of
the combined entity.

         The Company has instituted a program in order to become year 2000
compliant. The ultimate cost of this program has not been and is not expected to
be material to the Company's consolidated financial position or results of
operations. Although management believes the Company has an adequate program in
place in order to become year 2000 compliant, there can be no assurance that the
program ultimately will be successful.

                        REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders
of Watson Pharmaceuticals, Inc.

In our opinion, based upon our audits and the reports of other auditors, the
consolidated financial statements listed in the accompanying index on page F-1
present fairly, in all material respects, the financial position of Watson
Pharmaceuticals, Inc. and its subsidiaries at December 31, 1997 and 1996, and
the results of their operations and their cash flows for each of the three years
in the period ended December 31, 1997, in conformity with generally accepted
accounting principles. These financial statements are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements based on our audits. We did not audit the financial
statements of Somerset Pharmaceuticals, Inc. (Somerset), an entity which is 50%
owned by the Company. The Company's investment in Somerset aggregated
$27,643,000 and $24,653,000 at December 31, 1997 and 1996, respectively, and its
equity in the earnings of Somerset totaled $12,672,000, $20,100,000 and
$24,800,000 for the years ended December 31, 1997, 1996, and 1995, respectively.
In addition, we did not audit the financial statements of Oclassen
Pharmaceuticals, Inc. (Oclassen), a wholly owned subsidiary, which statements
reflect total assets of $35,900,000 at December 31, 1996, and total revenues of
$34,421,000 and $29,247,000 for the years ended December 31, 1996 and 1995,
respectively. Those financial statements were audited by other auditors whose
reports thereon have been furnished to us, and our opinion expressed herein,
insofar as it relates to the amounts included for Somerset and Oclassen, is
based solely on the reports of each of the respective other auditors. We
conducted our audits of the these statements in accordance with generally
accepted auditing standards which 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, assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits and the respective reports of other auditors provide a reasonable basis
for the opinion expressed above.

To the Board of Directors of
   Somerset Pharmaceuticals, Inc.:

We have audited the accompanying consolidated balance sheets of Somerset
Pharmaceuticals, Inc. and subsidiaries as of December 31, 1997 and 1996, and
related consolidated statements of income, stockholders' equity, and cash flows
for each of the three years in the period ended December 31, 1997 (not presented
separately herein). These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all
material respects, the financial position of Somerset Pharmaceuticals, Inc. and
subsidiaries as of December 31, 1997 and 1996, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1997 in conformity with generally accepted accounting principles.

To Oclassen Pharmaceuticals, Inc.;

responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

fairly, in all material respects, the financial position of Oclassen
Pharmaceuticals, Inc. as of December 31, 1995 and 1996, and the results of its
operations and its cash flows for each of the years then ended in conformity
with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.       DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

         DESCRIPTION OF BUSINESS AND PRINCIPLES OF CONSOLIDATION

         Watson Pharmaceuticals, Inc. ("Watson" or the "Company") is engaged in
the development, production, marketing and distribution of off-patent and
proprietary pharmaceutical products. The consolidated financial statements
include the accounts of wholly owned and majority owned subsidiaries after
elimination of intercompany accounts and transactions. The preparation of
consolidated financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts in the financial statements and accompanying notes.
Actual results could differ from those estimates.

         The Company's significant wholly owned subsidiaries include Watson
Laboratories, Inc. ("Watson Labs"), Circa Pharmaceuticals, Inc. ("Circa"),
Oclassen Pharmaceuticals, Inc. ("Oclassen"), and Royce Laboratories, Inc.
("Royce"). Circa, Oclassen and Royce were acquired by Watson in July 1995,
February 1997 and April 1997, respectively. All three acquisitions were
accounted for as poolings of interests, and accordingly, the Company's
consolidated financial statements have been restated to include the results of
operations, financial position and cash flows from all three entities (Note 2).

         Investments are accounted for under the equity method of accounting
where the Company can exert significant influence and ownership does not exceed
50%. These investments include Somerset Pharmaceuticals, Inc. and ANCIRC.
Investments in which the Company holds less than a 20% interest and does not
exert significant influence are accounted for under the cost method of
accounting. The Company's investment in Andrx Corporation ("Andrx") is accounted
for under the cost method of accounting.

         FAIR VALUE OF FINANCIAL INSTRUMENTS

         The carrying amounts of cash, cash equivalents, marketable securities,
accounts and other receivables, accounts payable, accrued expenses and debt
approximate fair value. The fair value of cash equivalents, marketable
securities and the Company's investment in Andrx is based on quoted market
prices at December 31, 1997 and 1996.

         CASH, CASH EQUIVALENTS AND MARKETABLE SECURITIES

         The fair market value of the Company's cash, cash equivalents and
marketable securities, all of which mature in 1998, consisted of the following:

                          WATSON PHARMACEUTICALS, INC.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

         Cash equivalents are highly liquid investments with original maturities
of three months or less. Investments with maturity dates between three and
twelve months are considered to be marketable securities. All of the Company's
debt and equity securities are classified as available-for-sale securities.
Unrealized gains or losses on these securities are excluded from earnings and
are reported as a separate component of stockholders' equity, net of applicable
income taxes, until realized. Realized gains and losses are determined on the
specific identification method and are reported in investment and other income.
Realized gains and losses were not material for the years ended December 31,
1997 and 1996. In 1995, the Company realized a gain of $6.2 million from the
sales of marketable securities.

         INVENTORIES

         Inventories are stated at the lower of cost (first-in, first-out
method) or market.

         PROPERTY AND EQUIPMENT

         Property and equipment are stated at cost, less accumulated
depreciation. Major renewals and improvements are capitalized, while routine
maintenance and repairs are expensed as incurred. At the time properties are
retired from service, the cost and accumulated depreciation are removed from the
respective accounts and the related gains or losses are reflected in income.

         Depreciation expense is computed principally on the straight-line
basis, over estimated useful lives of two to ten years for furniture, fixtures
and equipment and thirty years for buildings and building improvements.
Leasehold improvements and assets recorded under capital leases are amortized on
the straight-line basis over the respective lease terms or the estimated useful
life of the assets, ranging from five to thirty years.

         PRODUCT RIGHTS

         Product rights are stated at cost, less accumulated amortization, and
are amortized ratably over estimated lives of 17 years or less. The accumulated
amortization related to product rights was $8.5 million and $1.3 million at
December 31, 1997 and 1996, respectively.

         POTENTIAL IMPAIRMENT OF LONG-LIVED ASSETS

         The Company annually evaluates its long-lived assets, including product
rights, for potential impairment. When circumstances indicate that the carrying
amount of the asset may not be recoverable, as demonstrated by estimated future
cash flows, an impairment loss would be recorded based on fair value.

         REVENUE RECOGNITION

         The Company recognizes revenue, net of sales discounts and allowances,
from the sale of its pharmaceutical products upon shipment.

         PRODUCT SALES TO MAJOR CUSTOMERS

         In 1997, two customers in the aggregate accounted for 23% of the
Company's product sales, 12% and 11%, individually. In 1996, one customer
accounted for 10% of product sales. In 1995, no individual customer accounted
for more than 10% of product sales.

         RESEARCH AND DEVELOPMENT ACTIVITIES

         The costs associated with the development, testing and approval of
pharmaceutical products are expensed as incurred.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

         INCOME TAXES

         Income taxes are accounted for using an asset and liability approach
which requires the recognition of deferred tax assets and liabilities for the
expected future tax consequences of temporary differences between the financial
statement and tax bases of assets and liabilities at the applicable tax rates. A
valuation allowance is provided when it is more likely than not that some
portion or all of the deferred tax assets will not be realized.

         EARNINGS PER SHARE ("EPS")

         Basic earnings per share is computed by dividing net income by the
weighted average number of common shares outstanding in each year. Diluted
earnings per share is computed by dividing net income by the weighted average
number of common shares outstanding plus any potential dilution that could occur
if options and warrants were converted into common stock in each year.

         In 1997, the Company adopted Statement of Financial Accounting
Standards No. 128, "Earnings per Share", ("SFAS 128"). In accordance with the
implementation provisions of SFAS 128, the Company has restated earnings per
share in the Consolidated Statements of Income for the years ended December 31,
1996 and 1995. The unaudited quarterly data for the first three quarters of 1997
and for 1996 presented in Note 10 have also been restated to comply with the
provisions of SFAS 128. A reconciliation of the numerators and the denominators
of basic and diluted earnings per share for the years ended December 31, 1997,
1996, and 1995 is as follows (in thousands, except for EPS):

         In October 1997, the Company effected a two-for-one stock split in the
form of a 100% stock dividend. All share and per share amounts for the reported
periods have been restated to reflect the stock split.

         CONCENTRATION OF CREDIT RISK

         The Company is subject to a concentration of credit risk with respect
to its trade receivable balance, all of which are due from service providers,
distributors, wholesalers and chain drug stores in the health care and
pharmaceutical industries throughout the United States. The Company performs
ongoing credit evaluations of its customers and maintains reserves for potential
uncollectible accounts. Actual losses from uncollectible accounts have been
within management's expectations.

standards for the reporting of information about operating segments of a
business. Generally, financial information is required to be reported on the
basis that it is used internally by management for evaluating segment
performance.

         SFAS 130 and SFAS 131 address disclosure matters and will have no
effect on the Company's consolidated financial position, results of operations
or cash flows. The Company will adopt SFAS 130 and SFAS 131 in 1998.

         RECLASSIFICATIONS

         Certain amounts in the 1995 and 1996 financial statements have been
reclassified to conform with the 1997 presentation. These reclassifications had
no effect on net income or retained earnings.

2.       MERGERS AND ACQUISITIONS

         ACQUISITION OF ROYCE

         On April 16, 1997, the stockholders of Royce approved the merger with
Watson and Royce became a wholly owned subsidiary of the Company. Royce
develops, manufactures and markets off-patent prescription drugs in solid dosage
forms (tablets and capsules). Under the terms of the Royce merger agreement,
Royce stockholders received 0.19 share of the Company's common stock for each
Royce share. Accordingly, the Company issued approximately 5.2 million shares of
its common stock for all of the outstanding common shares of Royce. The merger
qualified as a tax-free reorganization for federal income tax purposes and was
accounted for as a pooling of interests. The Company's consolidated financial
statements have been retroactively restated to include the results of Royce for
all periods presented. A one-time charge of $5.8 million for merger-related
expenses was recorded in the quarter ended June 30, 1997. These expenses
included investment banking fees and other costs related to the consolidation of
operations between the two companies.

         ACQUISITION OF OCLASSEN

         On February 26, 1997, the stockholders of Oclassen approved the merger
with Watson and Oclassen became a wholly owned subsidiary of the Company.
Oclassen develops specialty prescription pharmaceuticals to prevent and treat
skin diseases, and markets these products to dermatologists. Under the terms of
the Oclassen merger agreement, Oclassen stockholders received 0.37 share of the
Company's common stock for each Oclassen share. Accordingly, the Company issued
approximately 6.6 million shares of its common stock for all of the outstanding
common shares of Oclassen. The merger qualified as a tax-free reorganization for
federal income tax purposes and was accounted for as a pooling of interests. The
Company's consolidated financial statements have been retroactively restated to
include the results of Oclassen for all periods presented. A one-time charge of
$8.9 million for merger-related expenses was recorded in the quarter ended March
31, 1997. These expenses included investment banking fees and other costs
related to the consolidation of operations between the two companies.

         The combined financial results of the Company, Oclassen, and Royce
include adjustments and reclassifications made to conform accounting policies
and financial statement presentations of the three companies. Intercompany
transactions between the three companies for the periods presented were not
material.

         SUBSEQUENT EVENT-ACQUISITION OF THE RUGBY GROUP, INC. ("RUGBY")

         On February 27, 1998, Watson completed its acquisition of Rugby from
Hoechst Marion Roussel, Inc. Rugby develops, manufactures, and markets a wide
array of off-patent pharmaceutical products. Under the terms of the agreement,
the Company acquired Rugby and its ANDAs, which include several licensed
products, plus Rugby's sales and marketing operations for U.S. off-patent
pharmaceuticals. The transaction also included Rugby's product development group
and product pipeline. The agreement provided for an initial payment of
approximately $67.5 million in cash and contingent payments based on certain
future sales and operating results.

         ACQUISITION OF PRODUCTS FROM G. D. SEARLE & CO. ("SEARLE")

         In the fourth quarter of 1997, the Company acquired the U.S. rights to
certain Searle branded off-patent oral contraceptive products. The FDA approved
one of these products, Trivora(R) (levonorgestrel and ethinyl estradiol), in
February 1998. Under the terms of this agreement, cash of $85.0 million was paid
through December 31, 1997, which included $5.0 million for Trivora(R). The
Company will pay a total of $45.0 million for Trivora(R), with the remaining
$40.0 million to be paid in 1998. The Company also acquired the U.S. rights to
additional oral contraceptive products from Searle (the "Future Products").
Payment for these products is due upon achievement of certain events, which
include in certain instances, approvals by the FDA.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

         If all contingent events occur before July 1, 1999, the aggregate
acquisition cost for the Future Products will be $48.5 million plus certain
contingent payments.

         ACQUISITION OF PRODUCTS FROM COCENSYS, INC. ("COCENSYS")

         In October 1997, the Company acquired two products and two co-promotion
agreements from CoCensys. In addition, Watson also hired certain sales and
marketing personnel from CoCensys. A total of $9.0 million was paid from
available cash to fund this acquisition.

         ACQUISITION OF PRODUCT RIGHTS TO DILACOR XR(R)

         On June 30, 1997, the Company obtained the exclusive U. S. and certain
worldwide marketing, sales, and distribution rights to Dilacor XR(R) for $190.0
million in cash (payable as set forth below), future royalties, and an inventory
supply agreement. These product rights were capitalized and are amortized on the
straight-line basis over 17 years. The Company made scheduled payments to RPR of
$95.0 million through December 31, 1997, from its available cash. The remaining
scheduled payments are due as follows:

                          DUE DATE                AMOUNT
                      ---------------         -------------
                      January 1, 1998         $45.0 million
                      January 1, 1999          30.0 million
                      January 1, 2000          15.0 million
                      January 1, 2001           5.0 million
                                              -------------
                          Total               $95.0 million
                                              ==============

         Prior to the Company's purchase of the rights to Dilacor XR(R), Circa
and RPR were partners in the development of this product. Since 1993, the
Company has earned royalties from RPR's sales of Dilacor XR(R). Revenues earned
under this royalty arrangement were $14.2 million in 1997 (earned through the
termination date of June 30, 1997), $27.2 million in 1996 and $22.2 million in
1995.

         ACQUISITION OF CIRCA

         On July 17, 1995, the stockholders of the Company and Circa approved
the merger with Watson and Circa became a wholly owned subsidiary of the
Company. Under the terms of the Circa merger agreement, Circa stockholders
received 0.86 share of the Company's common stock for each Circa share.
Accordingly, the Company issued approximately 37.4 million shares of its common
stock for all of the outstanding common shares of Circa. The merger qualified as
a tax-free reorganization and was accounted for as a pooling of interests. The
Company's consolidated financial statements have been retroactively restated to
include the results of Circa for all periods presented. A one-time charge of
$13.9 million for merger-related expenses was recorded in the quarter ended
September 30, 1995. These expenses included investment banking fees and other
costs related to the consolidation of operations between the two companies.

         Prior to its merger with the Company, Circa maintained stock award
plans for key employees and officers. The stock granted under these plans
contained certain vesting provisions which required unearned compensation to be
recorded for the fair market value of the shares issued. The stock awards were
converted to equivalent common shares in the Company pursuant to the merger
exchange ratio. Compensation expense was charged on the straight-line basis to
selling, general and administrative expense over the related vesting periods and
was fully amortized during the year ended December 31, 1996.

         INVESTMENT IN SOMERSET PHARMACEUTICALS,INC.("SOMERSET") JOINT VENTURE

         The Company owns 50% of the outstanding common stock of Somerset and
utilizes the equity method to account for this investment. Somerset manufactures
and markets the product Eldepryl(R), which is used in the treatment of
Parkinson's disease. Income recognized from Somerset was approximately $12.7
million, $20.1 million, and $24.8 million in 1997, 1996, and 1995, respectively.
Income is composed of the Company's 50% share of Somerset's earnings and
management fees, offset by amortization of goodwill. The net excess of the cost
of this investment over the fair value of net assets acquired was $6.4 million
and $7.4 million at December 31, 1997 and 1996, respectively. Such goodwill is
amortized on the straight-line basis over 15 years.

         Somerset has been notified by the Internal Revenue Service ("IRS") that
it may be subject to additional income taxes and interest for its 1993, 1994,
and 1995 tax years. The IRS has proposed adjustments relating to credits claimed
under Internal Revenue Code Section 936. These proposed adjustments amount to
approximately $13.0 million of additional income tax and interest charges, 50%
of which would be Watson's share. Management of Somerset believes that it has
complied with all relevant tax laws and intends to vigorously defend its
position on this matter.

         INVESTMENT IN OTHER JOINT VENTURES

         The Company has entered into several other joint ventures, including
ANCIRC, the Company's collaboration with Andrx, and two agreements with
China-based Changzhou No. 4 Pharmaceuticals Factory. Watson recognized losses
from other joint ventures of approximately $2.0 million, $2.2 million, and $1.7
million in 1997, 1996, and 1995, respectively.

         OTHER LONG-TERM INVESTMENTS

         Other long-term investments are comprised primarily of the Company's
investment in Andrx. Andrx develops advanced controlled-release drug delivery
systems and distributes certain off-patent pharmaceutical products manufactured
by others. Andrx trades publicly on the Nasdaq Stock Market, under the symbol
ADRX. At December 31, 1997, the Company owned 2.7 million common shares of
Andrx, which represents approximately 18.5% of the total Andrx common shares
outstanding. This investment included 600,000 shares of Andrx purchased in June
1997 for $15.3 million in cash. Watson accounts for this investment using the
cost method, adjusted to fair value. At December 31, 1997, the Company recorded
an unrealized gain of $33.1 million (net of income taxes of $22.1 million) on
its investment in Andrx, which is included as a separate component of
stockholders' equity.

         At December 31, 1997, the Company maintained two financing agreements,
which are summarized as follows.

         In 1997, the Company entered into an agreement with a bank (the "1997
financing agreement") that provided for a $50.0 million revolving, unsecured
line of credit which expires on March 31, 1998. This commitment was subsequently
increased to $75.0 million in January 1998. The 1997 financing agreement
provides favorable interest rates equal to the bank's Base Rate (8.50% per annum
at December 31, 1997) or a LIBOR Rate (as defined in the 1997 financing
agreement) plus 0.75%. Under the 1997 financing agreement, the Company must
maintain specified financial ratios and comply with certain restrictive
covenants. No borrowings have been made under the 1997 financing agreement.

         In 1994, the Company entered into an agreement with a bank (the "1994
financing agreement"), which has been amended and which provided for several
financing facilities. As of December 31, 1997, the facilities available under
the 1994 financing agreement were (i) a $20.0 million revolving, unsecured line
of credit which expires on August 31, 1998, and (ii) the balance of an original
$5.0 million term loan. The 1994 financing agreement provides for variable
interest rates for the $20.0 million revolving, unsecured line of credit equal
to the bank's Reference Rate (8.50% per annum at December 31, 1997) minus 0.25%
or other short-term rates based on various interest rate bases. Under the 1994
financing agreement, the Company must maintain specified financial ratios and
comply with certain restrictive covenants. With the exception of the original
$5.0 million term loan noted above, no borrowings have been made under the 1994
financing agreement.

         The exercise of stock options represents a tax benefit and has been
reflected as a reduction of income taxes payable and an increase to additional
paid-in capital. Such benefits recorded were $10.9 million, $7.8 million and
$6.8 million for the years ended December 31, 1997, 1996 and 1995, respectively.
Income taxes of $1.6 million have been provided for the possible distribution of
approximately $21.0 million of undistributed earnings related to the Company's

         The Company had net operating loss ("NOL") carryforwards at December
31, 1997 of approximately $15.0 million and $13.0 million for federal and
Florida state income tax purposes, respectively. During 1997, the Company
utilized NOL carryforwards of approximately $2.0 million to offset federal
income. Due to restrictions imposed as a result of ownership changes to acquired
subsidiaries, the amount of the NOL carryforward available to offset future
taxable income is subject to limitation. The annual NOL utilization may be
further limited if additional changes in ownership occur. The Company's NOL
carryforwards will begin to expire in 2003.

7.       STOCKHOLDERS' EQUITY

         PREFERRED STOCK

         In 1992, the Company authorized 2.5 million shares of no par preferred
stock. The Board of Directors has the authority to fix the rights, preferences,
privileges and restrictions, including dividend rates, conversion and voting
rights, terms and prices of redemptions and liquidation preferences without vote
or action by the stockholders. At December 31, 1997, no preferred stock was
issued.

         STOCK OPTION PLANS

         The Company has adopted several stock option plans that authorize the
granting of options to purchase the Company's common stock subject to certain
conditions. Under these plans, the Company has reserved 5.0 million shares for
issuance at December 31, 1997. The options are granted at the fair market value
of the shares underlying the options at the date of the grant, generally become
exercisable over a five-year period and expire in ten years. In conjunction with
the mergers with Circa, Oclassen, and Royce, certain stock option and warrant
plans were assumed by the Company. The options and warrants in these plans were
adjusted by the individual exchange ratios specified in each merger agreement.
No additional options or warrants will be granted under any of the assumed
plans.

         The Company adopted the disclosure provisions of Statement of Financial
Accounting Standards No. 123, "Accounting for Stock-Based Compensation" ("SFAS

in accordance with Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees", and related interpretations, but provides pro forma
disclosures of net income and earnings per share as if the fair value method (as
defined in SFAS 123) had been applied beginning in 1995. Had compensation cost
been determined using the fair value method prescribed by SFAS 123, the
Company's net income and earnings per share would have been as follows:

the date of grant using the Black-Scholes option pricing model with the
following weighted average assumptions used for grants in 1997, 1996 and 1995,
respectively: no dividend yield; expected volatility of 49%, 51% and 55%;
risk-free interest rate of 6.15%, 6.18% and 6.43% per annum; and expected terms
ranging from approximately three to eight years. Weighted averages are used
because of varying assumed exercise dates.

         A summary of the status of the Company's stock option plans as of
December 31, 1997, 1996 and 1995, and for the years then ended is presented

9.       COMMITMENTS AND CONTINGENCIES

         EMPLOYEE RETIREMENT PLAN

         The Company maintains a 401(k) retirement plan covering substantially
all employees. Monthly contributions are made by the Company based upon the
employee contributions to the plan. The Company contributed approximately
$398,000, $472,000 and $296,000 to the retirement plan for the years ended
December 31, 1997, 1996, and 1995, respectively.

         LEGAL MATTERS

         In March 1996, the Company paid $2.7 million in settlement of all
outstanding claims related to an inquiry by the United States Department of
Justice as to possible violations of the False Claims Act in respect of drugs
sold by Circa prior to cessation of these product sales in 1990. The Company had
established a reserve at December 31, 1995 for the full amount of the
settlement.

         The Company is involved in various disputes and litigation matters
which arise in the ordinary course of business. The litigation process is
inherently uncertain and it is possible that the resolution of these disputes
and lawsuits may adversely affect the Company. Management believes, however,
that the ultimate resolution of such matters will not have a material adverse
impact on the Company's consolidated financial position or results of
operations.

adoption of SFAS 128 and for acquisitions in 1997 accounted for under the
pooling of interests method as further discussed in Note 1 and Note 2,
respectively. Accordingly, this information varies from historical Form 10-Q
filings with the Securities and Exchange Commission prior to the effective dates
of these transactions.

                                   THE CREDIT

        SECTION II.1      THE REVOLVING LOANS.

                  (a) THE REVOLVING COMMITMENT. Bank agrees, on the terms and
         conditions hereinafter set forth, to make loans ("REVOLVING LOANS") to
         Borrower from time to time during the period from the date hereof to up
         to, but not including, the Maturity Date in an aggregate amount not to
         exceed, at any one time outstanding, the Revolving 

                                      -7-
<PAGE>

Commitment, as such amount may be reduced pursuant to Section 2.1(d).

                  Each borrowing (a "BORROWING") of a Revolving Loan shall be in
a minimum amount of $1,000,000; provided that every selection of, conversion to,
or renewal of, the Libor Rate Option shall be in a minimum principal amount of
$1,000,000 or an integral multiple of $1,000,000 above such amount. Within the
limits of the Revolving Commitment and prior to the Maturity Date, Borrower may
borrow, repay pursuant to Section 2.2(b), and reborrow under this Section
2.1(a).

                  (b) LIMITATION ON REVOLVING LOANS. Bank shall have no
obligation to make Revolving Loans hereunder to the extent they would cause the
outstanding amount of Revolving Loans to exceed the Revolving Commitment.

                  (c) MAKING THE REVOLVING LOANS. Borrower may borrow under the
Revolving Commitment on any Business Day, provided that Borrower shall give Bank
a Standard Notice specifying (i) the amount of the proposed Borrowing, and (ii)
the requested date of the Borrowing. Upon satisfaction of the applicable
conditions set forth in Article IV, the proceeds of all such Revolving Loans
will then be made available to Borrower by Bank by crediting the account of
Borrower on the books of Bank, or as otherwise directed by Borrower.

                  The Standard Notice may be given in writing (including
facsimile transmission) signed by an authorized officer of Borrower or orally,
but if the Standard Notice is provided orally, Borrower shall confirm the oral
Standard Notice on the same day in writing (including facsimile transmission) no
later than 1:00 p.m., California time, and any conflict regarding a written or
oral notice and Bank's books and records applicable to the same Borrowing shall
be conclusively determined by Bank's books and records absent manifest error.
Bank shall not incur any liability to Borrower in acting upon any oral or
written notice of Borrowing which Bank believes in good faith to have been given
by a Person duly authorized to borrow on behalf of Borrower.

                  (d) REDUCTION OF THE REVOLVING COMMITMENT. Borrower shall have
the right, upon at least 2 Business Days prior written notice to Bank, to
terminate in whole or reduce in part the unused portion of the Revolving
Commitment, without premium or penalty, provided that each partial reduction
shall be in the aggregate amount of $5,000,000 or an integral multiple thereof
and that such reduction shall not reduce the Revolving Commitment to an amount
less than the amount of the Revolving Loans outstanding hereunder on the
effective date of the reduction. Such notice shall be irrevocable and such
reduction shall not be reinstated.

                  (e) REVOLVING NOTE. The Revolving Loans made by Bank pursuant
hereto shall be evidenced by a promissory note of Borrower, substantially in the
form of EXHIBIT A, with any appropriate insertions (the "REVOLVING NOTE"),
payable to the order of Bank and representing the obligation of Borrower to pay
the aggregate unpaid principal amount of all Revolving Loans made by Bank, with
interest thereon as prescribed in Section 2.3. Bank hereby is authorized to
record in its books and records and on any schedule annexed

                                      -8-
<PAGE>

to the Revolving Note, the date and amount of each Revolving Loan made by Bank,
and the date and amount of each payment of principal thereof, and in the case of
Libor Rate Option Revolving Loans, the Libor Rate, the Libor Rate Portion, and
the Rate Period with respect thereto, and any such recordation shall constitute
PRIMA FACIE evidence of the accuracy of the information so recorded; provided
that failure by Bank to effect such recordation shall not affect Borrower's
obligations hereunder. Prior to the transfer of a Revolving Note, Bank shall
record such information on any schedule annexed to and forming a part of such
Revolving Note.

        SECTION II.2      REPAYMENT.

                  (a) MANDATORY REPAYMENTS. The aggregate principal amount of
the Revolving Loans outstanding on the Maturity Date, together with accrued
interest thereon, shall be due and payable in full on the Maturity Date. If at
any time the aggregate outstanding Borrowings exceed the Revolving Commitment
then in effect, Borrower immediately shall repay the excess to Bank.

                  (b) OPTIONAL PAYMENT. Borrower shall have the right at its
option from time to time to prepay the Base Rate Portion in whole or in part
without premium or penalty. Borrower shall have no right to prepay any part of
the Libor Rate Portion at any time without the prior written consent of Bank
except that (i) Borrower may prepay any part of any Rate Segment at the
expiration of the Rate Period corresponding to such Rate Segment, and (ii)
Borrower may prepay any part of any other Rate Segment so long as Borrower also
makes payment to Bank of any amounts payable under Section 3.6(b) in connection
therewith. Prepayments shall be made by giving Bank written notice thereof
(which shall be irrevocable) by no later than 11:00 a.m. (California time) on
the proposed date of prepayment, specifying the date, amount, and type of
prepayment, and upon such date the amount so specified, accrued interest
thereon, and any amounts payable under Section 3.6(b) shall be due and payable.

        SECTION II.3      INTEREST RATE AND PAYMENT DATES.

                  (a) PAYMENT. The principal balance of the Note shall be paid
in accordance with the terms set forth in the Note. Accrued interest on the Base
Rate Portion shall be due and payable on the last Business Day of each month
commencing on December 31, 1997. Interest on each Rate Segment of the Libor Rate
Portion which has a Rate Period shall be due and payable on the last day of the
corresponding Rate Period. After maturity of any part of a Note (by acceleration
or otherwise), interest on such part of the Note shall be due and payable ON
DEMAND.

                  (b) INTEREST RATE. The unpaid principal amount of the Note
shall bear interest for each day until due on one or more bases selected by
Borrower from among the interest rate options (the "INTEREST RATE OPTIONS") set
forth below. Borrower understands and agrees: (i) that Bank may from time to
time determine that the right of Borrower to select, convert to, or renew the
Libor Rate Option is not available, which availability shall not be unreasonably
withheld, (ii) that Borrower shall not have the right to select, convert

                                      -9-
<PAGE>

to, or renew the Libor Rate Option at any time that a Default or Event of
Default has occurred and is continuing, and (iii) that subject to the provisions
hereof, Borrower may select any number of options to apply simultaneously to
different parts of the unpaid principal amount of the Note and may select any
number of Rate Segments to apply simultaneously to different parts of the Libor
Rate Portion.

                         AVAILABLE INTEREST RATE OPTIONS

BASE RATE OPTION:  A rate per annum for each day equal to the Base Rate.

LIBOR RATE OPTION: A rate per annum for each day equal to the Libor Rate for
such day plus three quarters (0.75) of a percentage point.

                  (c) RATE PERIODS. At any time when Borrower selects, converts
to, or renews the Libor Rate Option, Borrower shall fix a period (the "RATE
PERIOD") which shall be one, two, or three weeks or one, two, or three months,
during which the Libor Rate Option shall apply to the corresponding Rate
Segment; PROVIDED, that Borrower may not elect a Rate Period that will end after
the Maturity Date. Bank's right to payment of principal and interest under the
Note shall in no way be affected by the fact that one or more Rate Periods may
be in effect.

                  (d) INTEREST AFTER MATURITY. Upon the occurrence and during
the continuation of an Event of Default, the principal amount of any part of the
Base Rate Portion shall bear interest for each day until paid (before and after
judgment) at a rate per annum (based on a year of 365 days and actual days
elapsed) which for each day shall be the greater of (a) 2% above the Base Rate
Option on the day such amount became due, and (b) 2% above the Base Rate Option,
such interest rate to change automatically from time to time effective as of the
effective date of each change in the Base Rate. Upon the occurrence and during
the continuation of an Event of Default, the principal amount of any part of the
Libor Rate Portion shall bear interest for each day until paid (before and after
judgment) (a) until the end of the applicable then current Rate Period at a rate
per annum 2% above the Libor Rate Option otherwise applicable to such part, and
(b) thereafter in accordance with the previous sentence.

                  (e) SELECTION, CONVERSION OR RENEWAL OF RATE OPTIONS. Subject
to the other provisions hereof, Borrower may select any Interest Rate Option to
apply to the borrowings evidenced by the Note. Subject to the other provisions
hereof, Borrower may convert any part of the unpaid principal amount of the Note
from any Interest Rate Option to the other Interest Rate Option: (a) at any time
with respect to the conversion from the Base Rate Option to the Libor Rate
Option, and (b) at the expiration of any Rate Period with respect to conversion
from or renewals of the Libor Rate Option as to the Rate Segment corresponding
to such expiring Rate Period (or at any other time, subject to Section 3.6(b)).
Whenever Borrower desires to select, convert, or renew the Libor Rate Option,
Borrower shall give Bank a Standard Notice thereof (which shall be irrevocable),
specifying the date, amount, and type of the proposed new Rate Option. If such
notice has been duly given, and if Bank approves the proposed selection,
conversion, or renewal, on 

                                      -10-
<PAGE>

and after the date specified in such notice, interest shall be calculated upon
the unpaid principal amount of the Note taking into account such selection,
conversion or renewal.

                  (f) BASE RATE FALLBACK. If any Rate Period expires, any part
of the Rate Segment corresponding to such Rate Period which has not been
converted or renewed in accordance with Section 2.3(e) hereof automatically
shall be converted to the Base Rate Option. If Borrower fails to select, or if
Bank fails to approve an Interest Rate Option to apply to the borrowings
evidenced by the Note, such borrowings shall be deemed to be at the Base Rate
Option. If at any time Bank shall have determined in good faith (which
determination shall be conclusive) that the accrual of interest at the Libor
Rate Option has been made unascertainable, impractical, or unlawful by
compliance by Bank in good faith with any law (including common law),
constitution, statute, treaty, regulation, rule, ordinance, order, injunction,
writ, decree or award of any government or political subdivision or any agency,
authority, bureau, central bank, commission, department or instrumentality of
either, or any court, tribunal, grand jury or arbitrator, in each case whether
foreign or domestic, or administration thereof by any official body charged with
the interpretation or administration thereof or with any request or directive of
any such event, the outstanding principal amount of the Note subject to the
Libor Rate Option shall accrue interest at the Base Rate Option and Borrower
shall not have the right to select the Libor Rate Option.

         SECTION II.4 CLOSING FEE. On the date of the execution and delivery of
this Agreement, Borrower shall pay to Bank a closing fee ("CLOSING FEE") in an
amount equal to .05% times the Revolving Commitment.

         SECTION II.5 UNUSED COMMITMENT FEES. On the last Business Day of each
month during the term of this Agreement, Borrower shall pay to Bank an unused
commitment fee in an amount equal to .20% per annum times the Average Unused
Portion of the Revolving Commitment; PROVIDED, HOWEVER, that the unused
commitment fee shall not begin to accrue until the date on which Bank has sent a
written notice to Borrower that each of the conditions precedent set forth in
Section 4.1 have been satisfied or waived.

                                   ARTICLE III
                GENERAL PROVISIONS CONCERNING THE REVOLVING LOANS

         SECTION III.1 USE OF PROCEEDS. The proceeds of the Revolving Loans
hereunder shall be used by Borrower for its general working capital and
corporate purposes (including, without limitation, the financing of Permitted
Acquisitions), consistent with the terms and conditions hereof.

         SECTION III.2 COMPUTATION OF INTEREST AND FEES.

                  (a) CALCULATIONS. Interest in respect of the Base Rate Option
Revolving Loans shall be calculated on the basis of a 365 day year for the
actual days elapsed. Any change in the interest rate on a Base Rate Revolving
Loan resulting from a change in the Base Rate shall become effective as of the
opening of business on the day on which such

                                      -11-
<PAGE>

change in the Base Rate shall become effective. Interest in respect of the Libor
Rate Option Revolving Loans, and any fees payable hereunder, shall be calculated
on the basis of a 365 day year for the actual days elapsed.

                  (b) DETERMINATION BY BANK. Each determination of an interest
rate or fee by Bank pursuant to any provision of this Agreement shall be
conclusive and binding on Borrower in the absence of manifest error.

         SECTION III.3 PAYMENTS. Borrower shall make each payment of principal,
interest, and fees hereunder and under the Note, without setoff or counterclaim,
not later than 11:00 a.m. (California time) on the day when due in lawful money
of the United States of America to Bank at the office of Bank designated in
writing in immediately available funds. Any interest not paid when due shall be
compounded and shall thereafter accrue interest at the rate then applicable to
the Base Rate Portion of Borrowings hereunder (and if no Base Rate Portion of
Borrowings is outstanding, then at the rate applicable to such Borrowings as if
outstanding under the Base Rate Option).

         SECTION III.4 PAYMENT ON NON-BUSINESS DAYS. Whenever any payment to be
made hereunder or under the Note shall be stated to be due on a day which is not
a Business Day, such payment may be made on the next succeeding Business Day,
and with respect to payments of principal, interest thereon shall be payable at
the then applicable rate during such extension.

         SECTION III.5 REDUCED RETURN. If Bank shall have determined that any
applicable law, regulation, rule or regulatory requirement applicable to Bank
(collectively in this Section 3.5 "REQUIREMENT") regarding capital adequacy, or
any change therein, or any change in the interpretation or administration
thereof by any United States federal or state governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by Bank with any request or directive regarding capital
adequacy (whether or not having the force of law) of any such authority, central
bank or comparable agency, has or would have the effect of reducing the rate of
return on Bank's capital as a consequence of its Revolving Commitment and
obligations hereunder to a level below that which would have been achieved but
for such Requirement, change or compliance (taking into consideration Bank's
policies with respect to capital adequacy) by an amount deemed by Bank to be
material (which amount shall be determined by Bank's reasonable allocation of
the aggregate of such reductions resulting from such events), then from time to
time, within five Business Days after demand by Bank (including a calculation in
reasonable detail of such amount), Borrower shall pay to Bank such additional
amount or amounts as will compensate Bank for such reduction. Bank does not
currently have knowledge of any new Requirement or any pending change in any
existing Requirement that would result in such additional amounts being owed.

        SECTION III.6     INDEMNITIES AND LOSSES.

                  (a) INDEMNITIES. Whether or not the transactions contemplated
hereby shall be consummated, Borrower agrees to indemnify, defend, and hold
Bank, and the 

                                      -12-
<PAGE>

shareholders, officers, directors, employees and agents of Bank
(each, an "INDEMNIFIED PERSON"), harmless from and against any and all claims,
liabilities, losses, damages, costs and expenses (whether or not any of the
foregoing Indemnified Persons is a party to any litigation), including, without
limitation, reasonable attorneys fees and costs (including, without limitation,
the reasonable estimate of the allocated cost of in-house legal counsel and
staff) and costs of investigation, document production, attendance at a
deposition, or other discovery, prior to the assumption of defense by Borrower,
with respect to or arising out of any proposed acquisition by Borrower or any of
its Subsidiaries of any Person or any securities (including a self-tender), this
Agreement or any use of proceeds hereunder, or any claim, demand, action or
cause of action being asserted against Borrower or any of its Subsidiaries
(collectively, the "INDEMNIFIED LIABILITIES"), provided that Borrower shall have
no obligation hereunder with respect to Indemnified Liabilities arising from the
gross negligence or willful misconduct of, or violations of this Agreement by,
any such Indemnified Persons. If any claim is made, or any action, suit or
proceeding is brought, against any Indemnified Person of the type contemplated
by this Section, the Indemnified Person shall notify Borrower within thirty days
of Bank being notified in writing of the commencement of such action, suit or
proceeding, and Borrower will assume the defense of such action, suit or
proceeding, employing counsel selected by Borrower and reasonably satisfactory
to the Indemnified Person, and pay the fees and expenses of such counsel. This
covenant shall survive termination of this Agreement and payment of the
outstanding Note for a period of five years.

                  (b) FUNDING LOSSES. Borrower agrees to indemnify Bank and to
hold Bank harmless from any reasonable loss or expense including, but not
limited to, any such loss or expense arising from interest or fees payable by
Bank to lenders of funds obtained by it in order to maintain its Libor Rate
Option Revolving Loans hereunder, which Bank may sustain or incur as a
consequence of (i) payment, prepayment or conversion of any part of any Rate
Segment of the Libor Rate Portion on a day other than the last day of the
corresponding Rate Period (whether or not any such payment is pursuant to demand
by Bank under the Note and whether or not any such payment, prepayment or
conversion is consented to by Bank, unless Bank shall have expressly waived such
indemnity in writing); (ii) default by Borrower in making a conversion or
continuation after Borrower has given a notice thereof, (iii) default by
Borrower in making any payment after Borrower has given a notice of payment,
(iv) attempt by Borrower to revoke in whole or part any irrevocable notice given
pursuant to Section 2.3(e) hereof; or (v) breach of or default by any obligor in
the performance or observance of any covenant or condition in the Note, any
separate security, guarantee or suretyship agreement between Bank and any
obligor, or any other document executed and delivered to Bank by any Obligor in
connection with the indebtedness evidenced by the Note. If Bank sustains any
such loss or expense, it shall from time to time notify Borrower of the amount
reasonably determined in good faith by Bank (which determination shall be
conclusive) to be necessary to indemnify Bank for such loss or expense. Such
amount shall be due and payable by Borrower ON DEMAND (provided that Bank shall
give Borrower a written calculation of such amount in reasonable detail). This

         SECTION III.7 REQUIREMENTS OF LAW. In the event that any law,
regulation, or directive applicable to Bank or any change therein or in the
interpretation or application thereof or compliance by Bank with any request or
directive (whether or not having the force of law) from any United States
federal or state central bank or other governmental authority, agency or
instrumentality:

                  (a) does or shall impose, modify or hold applicable any
reserve, assessment rate, special deposit, compulsory loan or other requirement
(collectively in this Section 3.7 "REQUIREMENTS") against assets held by, or
deposits or other liabilities in or for the account of, advances or loans by, or
other credit extended by, or any other acquisition of funds by, any office of
Bank which are not otherwise included in the determination of any Libor Rate at
the last Borrowing, conversion or continuation date of a Revolving Loan;

                  (b) does or shall impose, modify, or hold applicable any of
the Requirements against the Revolving Commitment to extend credit;

                  (c)      does or shall impose on Bank any other condition;

and the result of any of the foregoing is to increase the cost to Bank of
making, renewing, or maintaining its Revolving Commitment, or the Libor Rate
Option Revolving Loans or to reduce any amount receivable thereunder (which
increase or reduction shall be determined by Bank's reasonable allocation of the
aggregate of such cost increases or reduced amounts receivable resulting from
such events), then, in any such case, Borrower shall pay to Bank, within five
Business Days of its demand, any additional amounts necessary to compensate Bank
for such additional cost or reduced amount receivable as determined by Bank with
respect to Sections 3.5 and 3.6 of this Agreement (provided that Bank shall give
Borrower a written calculation of reasonable detail of such amounts). If Bank
becomes entitled to claim any additional amounts pursuant to this subsection, it
shall notify Borrower of the event by reason of which it has become so entitled.
Such notice shall contain a statement incorporating the calculation as to any
additional amounts payable pursuant to the foregoing sentence, and such
statement submitted by Bank to Borrower shall be conclusive in the absence of
manifest error. Bank does not currently have knowledge of any new Requirement or
any pending change in any existing Requirement that would result in such
additional amounts being owed.

         SECTION V.1 REPRESENTATIONS AND WARRANTIES. Borrower represents and
warrants as follows:

                  (a) ORGANIZATION. Borrower and its Subsidiaries are duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation. Borrower and its Subsidiaries are (except, in
each case, where failure to comply with the foregoing would not result in a
Material Adverse Change) duly authorized, qualified and licensed in all
applicable jurisdictions, and under all applicable laws, regulations, ordinances
or orders of public authorities, to carry on its business in the locations and
in the manner presently conducted.

                  (b) AUTHORIZATION. The execution, delivery and performance by
Borrower of the Loan Documents, and the making of Borrowings hereunder, are
within Borrower's corporate powers, have been duly authorized by all necessary
corporate action, do not contravene (i) Borrower's charter, by-laws or other
organizational document or (ii) any material law or regulation (including
Regulations G, T, U and X) binding on or affecting

                                      -16-
<PAGE>

Borrower or its properties, and will not constitute an event of default under
any material agreement to which Borrower is a party or by which its assets or
properties may be bound. The execution, delivery and performance by the
Guarantors of the Guaranty is within each of the Guarantor's corporate powers,
has been duly authorized by all necessary corporate action, does not contravene
(i) any Guarantor's charter, by-laws or other organizational document or (ii)
any material law or regulation (including Regulations G, T, U and X) binding on
or affecting any Guarantor or its properties, and will not constitute an event
of default under any material agreement to which any Guarantor is a party or by
which its assets or properties may be bound.

                  (c) GOVERNMENTAL CONSENTS. No authorization or approval or
other action by, and no notice to or filing with, any governmental authority or
regulatory body (except routine reports required pursuant to the Securities
Exchange Act of 1934, as amended (if such act is applicable to Borrower), which
reports will be made in the ordinary course of business) is required for the due
execution, delivery and performance by Borrower or the Guarantors of the Loan
Documents.

                  (d) VALIDITY. The Loan Documents to which they are parties are
the binding obligations of Borrower and the Guarantors, enforceable in
accordance with their respective terms; except in each case as such
enforceability may be limited by bankruptcy, insolvency, reorganization,
liquidation, moratorium or other similar laws of general application and
equitable principles relating to or affecting creditors' rights.

                  (e) FINANCIAL CONDITION. The balance sheets of Borrower and
any of its consolidated Subsidiaries as at September 30, 1997 and the related
statements of income and retained earnings of Borrower and any of its
consolidated Subsidiaries, copies of which have been furnished to Bank, fairly
present the financial condition of Borrower and any of its consolidated
Subsidiaries as at such date and the results of the operations of Borrower and
any of its consolidated Subsidiaries for the period ended on such date, all
determined in accordance with GAAP (subject to the absence of footnotes and
normal year-end audit adjustments), consistently applied, and since September
30, 1997 there has not been a Material Adverse Change.

                  (f) LITIGATION. Except as set forth on SCHEDULE 5.1(F) hereto,
there is no known pending or threatened action or proceeding affecting Borrower
or any of its Subsidiaries before any court, governmental agency or arbitrator,
which may materially adversely affect the consolidated financial condition or
operations of Borrower and its Subsidiaries or which may result in a Material
Adverse Change.

                  (g) EMPLOYEE BENEFIT PLANS. Borrower and each of its ERISA
Affiliates has fulfilled its obligations, if any, under the minimum funding
standards of ERISA and the Internal Revenue Code with respect to each Plan and
is in compliance in all material respects with the applicable provisions of
ERISA and the Internal Revenue Code, and has not incurred any liability with
respect to any Plan under Title IV of ERISA. No reportable event has occurred
under Section 4043(b) of ERISA for which the PBGC requires 30 day notice. No
action by Borrower or of any ERISA Affiliate of Borrower to terminate or

                                      -17-
<PAGE>

withdraw from any Plan has been taken and no notice of intent to terminate a
Plan has been filed under Section 4041 of ERISA. No proceeding has been
commenced with respect to a Plan under Section 4042 of ERISA, and no event has
occurred or condition exists which might constitute grounds for the commencement
of such a proceeding.

                  (h) DISCLOSURE. No representation or warranty of Borrower
contained in this Agreement or any other document, certificate or written
statement furnished to Bank by or on behalf of Borrower for use in connection
with the transactions contemplated by this Agreement contains any known untrue
statement of a material fact or omits to state a known material fact (known to
Borrower in the case of any document not furnished by it) necessary in order to
make the statements contained herein or therein not misleading. There is no fact
known to Borrower (other than matters of a general economic nature) which
materially adversely affects the business, operations, property, assets or
condition (financial or otherwise) of Borrower and any of its Subsidiaries,
taken as a whole, which has not been disclosed herein or in such other
documents, certificates and statements furnished to Bank for use in connection
with the transactions contemplated hereby.

                  (i) ENVIRIONMENTAL MATTERS. Except as set forth in SCHEDULE

spilled, or otherwise disposed of any substance defined as hazardous or toxic by
any applicable federal, state or local law, rule, regulation, order or
directive, or any waste or by-product thereof, at any real property or any other
facility owned, leased or used by Borrower or any Subsidiary, in violation of
any applicable statutes, regulations, ordinances or directives of any
governmental authority or court, which violations reasonably may result in
uninsured liability to Borrower or any Subsidiary or any of their respective
officers, employees, representatives, agents or shareholders in an uninsured
amount exceeding $5,000,000 for all such violations; and the unresolved
violations set forth in said Schedule 5.1(i) will not result in liability to
Borrower or any Subsidiary or any of their respective officers, employees,
representatives, agents or shareholders in an amount exceeding $5,000,000 for
all such unresolved violations. Except as set forth in said Schedule, no
employee or other person has made a claim or demand in writing against Borrower
or any Subsidiary based on alleged damage to health caused by any such hazardous
or toxic substance or by any waste or by-product thereof, other than claims,
demand or charges which have been settled or satisfied; and the unsatisfied
claims or demands against Borrower or any Subsidiary set forth in said Schedule
5.1(i) will not result in uninsured liability to Borrower or any Subsidiary or
any of their respective officers, employees, representatives, agents or
shareholders in an amount exceeding $5,000,000 in excess of reserves on the
books of Borrower for all such unsatisfied claims or demands. Except as set
forth in said Schedule 5.1(i), neither Borrower nor any Subsidiary has been
charged in writing by any governmental authority with improperly using,
handling, storing, discharging or disposing of any such hazardous or toxic
substance or waste or by-product thereof or with causing or permitting any
pollution of any body of water, other than claims, demand or charges which have
been settled or satisfied; and the outstanding related charges set forth in said
Schedule 5.1(i) will not result in uninsured liability to Borrower or any
Subsidiary or any of their respective

                                      -18-
<PAGE>

officers, employees, representatives, agents or shareholders in an amount
exceeding $5,000,000 for all such outstanding charges.

                  (j) EMPLOYEE MATTERS. There is no known strike or work
stoppage in existence or threatened involving Borrower or any of its
Subsidiaries that may materially adversely affect the consolidated financial
condition or operations of Borrower and its Subsidiaries taken as a whole or
that reasonably could be expected to result in a Material Adverse Change.

                  (k) SOLVENCY. Borrower and the Guarantors, taken as a whole,
are Solvent.

                  (l) TITLE TO PROPERTIES. Borrower and each of its Subsidiaries
has good and marketable title to (or a valid leasehold or license in) all of its
material properties and assets subject to no liens, mortgages, pledges, security
interests, encumbrances or charges of any kind, except those as are permitted
under Section 6.2(c) hereof.

                  (m) TAX RETURNS. Except as set forth on SCHEDULE 5.1(M)
hereto, Borrower and its Subsidiaries has filed, or caused to be filed, in a
timely manner all tax returns, reports and declarations which are required to be
filed by it (including any automatic or granted extensions). All information in
such tax returns, reports and declarations is complete and accurate in all
material respects. Borrower and each of its Subsidiaries has paid or caused to
be paid all taxes due and payable or claimed due and payable in any assessment
received by it, except taxes the validity of which are being contested in good
faith by appropriate proceedings diligently pursued and available to Borrower or
its Subsidiaries and with respect to which adequate reserves have been set aside
on its books. Adequate provision has been made for the payment of all accrued
and unpaid Federal, State, county, local, foreign and other taxes whether or not
yet due and payable and whether or not disputed.

                  (n) COMPLIANCE WITH OTHER AGREEMENTS AND APPLICABLE LAWS.
Neither Borrower nor any of its Subsidiaries is in default in any material
respect under, or in violation in any material respect of any of the terms of,
any agreement, contract, instrument, lease or other commitment to which it is a
party or by which it or any of its assets are bound, the loss of which
reasonably could be expected to result in a Material Adverse Change, and
Borrower and each of its Subsidiaries is in compliance in all material respects
with all applicable provisions of laws, rules, regulations, licenses, permits,
approvals and orders of any foreign, Federal, State or local governmental
authority, except for those the failure to comply with which reasonably could
not be expected to result in a Material Adverse Change.

      7. RELEASE BY CONSULTANT. Consultant, for himself and for his

(collectively, the "Releasing Parties"), hereby releases and discharges each of
the Company, Royce and their respective stockholders, directors, officers,

Company or Royce had, now have, or hereafter may have against any of the
Companies' Released Parties, relating to Consultant's employment with the

unknown to the releasing or discharging party at the time of execution of said
release and discharge. All parties hereby expressly waive, surrender and agree
to forego any protection to which they would otherwise be entitled against one
another by virtue of the existence of any statute in any jurisdiction,
including, but not limited to, California. IT IS EXPRESSLY UNDERSTOOD AND AGREED
THAT ALL RIGHTS UNDER SECTION 1542 OF THE CIVIL CODE OF THE STATE OF CALIFORNIA
ARE EXPRESSLY WAIVED BY EACH PARTY. SECTION 1542 READS AS FOLLOWS:

      SECTION 1542. A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE

      EXECUTING THE RELEASE WHICH, IF KNOWN BY HIM, MUST HAVE MATERIALLY
      AFFECTED HIS SETTLEMENT WITH A DEBTOR.

      10. TERMINATION FOR DEATH, DISABILITY OR CAUSE. The Company may terminate
this Agreement and Consultant's consulting arrangement with the Company and

to perform the duties and services to be performed by him under this Agreement
for a consecutive period of three months or such shorter periods aggregating
three months in any 12-month period.

           (c) TERMINATION FOR CAUSE. Company may terminate Consultant's
consulting arrangement with Company and this Agreement at any time for Cause.
"Cause" shall mean: (i) a material breach or violation by Consultant of his
obligations under Sections 9, 10, 11, 12 or 13 of the Employment Agreement; (ii)
a material breach or violation by Consultant of his obligations under any
provision of this Agreement (other than Sections 9, 10, 11, 12 or 13 of the
Employment Agreement) or the failure of Consultant to materially perform his
duties or responsibilities hereunder (unless said material default is caused by
a Disability) after Consultant has been given 

                                       3

<PAGE>


at least thirty (30) days prior written notice together with an opportunity to
cure said breach, violation or failure during such thirty (30) day period;
provided, however, that Consultant shall only have the right to cure one breach
in any twelve consecutive month period during the Term; or (iii) actions by
Consultant constituting fraud and/or embezzlement.

      11. NO PARTNERSHIP NOR JOINT VENTURE; INDEPENDENT CONTRACTOR.

           (a) The parties hereto intend by this Agreement solely to effect the
appointment of Consultant as an independent contractor. No other relationship is
intended to be created between the parties hereto. Subject to Consultant's
rights and interests as a security holder of the Company, nothing in this
Agreement shall be construed as (i) giving Consultant any rights as an owner of
the business of the Company or Royce, (ii) giving the Company or Royce any
rights as a partner in or owner of any business of Consultant, (iii) entitling
Consultant to control in any manner the conduct of the Company's or Royce's
business or (iv) entitling the Company or Royce to control in any manner the
conduct of Consultant's business.

           (b) In performing the services described in this Agreement,
Consultant shall at all times operate as an independent contractor, maintaining
his own organization as distinct and separate from that of the Company and
Royce. Nothing in this Agreement shall be deemed to create or constitute the
relation of employer and employee between the Company and/or Royce, on the one
hand, and Consultant, on the other hand. Consultant, Royce and the Company
hereby acknowledge (i) that Consultant shall be solely responsible for and shall
pay all taxes in respect of Consultant's income and engagement hereunder, (ii)
Consultant has requested that the Company not withhold taxes and other amounts
from any payments of compensation to Consultant hereunder, and (iii) Consultant
shall be solely responsible for his health insurance, retirement and disability
protection and all other so-called "fringe benefits" and the Company or Royce
shall not in any way be responsible therefor, except as otherwise required by
the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended
("COBRA").

      12. CONSULTANT'S OTHER ACTIVITIES. Consultant has advised Company that he
intends to become the President and Chief Executive Officer of AMDG, Inc.
("AMDG") after his resignation from Company and Royce. Consultant has advised
Company and Royce regarding the business of AMDG and Company and Royce hereby
acknowledge that, as long as AMDG does not engage in the development,
manufacture, sale or marketing of generic pharmaceutical products, (i) such
activity shall not be grounds for termination of this Agreement; (ii) such
future employment shall not reduce the Company's and Royce's obligations to make
the payments required by Section 7(c) of the Employment Agreement; and (iii)
such activity shall not be deemed to violate the provisions of Section 11 of the
Employment Agreement.

      13. COMPANY GUARANTY. Company hereby guarantees to Consultant the due and
punctual payment and performance in full of all of the obligations of Royce
contained in this Agreement.

          "CONFIDENTIAL MATERIAL FILED SEPARATELY WITH THE COMMISSION"

                                                                   EXHIBIT 10.27


                            STOCK PURCHASE AGREEMENT

      THIS AGREEMENT is made as of August 25, 1997, among Hoechst Marion
Roussel, Inc., a Delaware corporation ("PARENT"), Marisub, Inc., a Delaware
corporation and the wholly-owned subsidiary of Parent ("SELLER"), and Watson
Pharmaceuticals, Inc., a Nevada corporation ("WATSON").

                                    RECITALS

      A. Seller owns all of the outstanding shares of capital stock ("Shares")
of The Rugby Group, Inc., a New York corporation (the "COMPANY"), which Shares
consist of 220 shares of common stock, 3,980 shares of first preferred stock and
2,400 shares of second preferred stock.

      B. Watson desires to purchase all the outstanding Shares from Seller and
Seller desires to sell such Shares to Watson, on the terms and subject to the
conditions herein contained.

                                   AGREEMENTS

      Therefore, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto, intending to
be legally bound, hereby agree as follows:

                                    ARTICLE I

          PURCHASE AND SALE OF SHARES; CLOSING AND MANNER OF PAYMENT

      1.1 AGREEMENT TO PURCHASE AND SELL SHARES. On the terms and subject to the
conditions contained in this Agreement, Watson shall purchase from Seller, and
Seller shall sell to Watson, all of the outstanding Shares. At the Closing (as
defined herein), Seller shall deliver to Watson certificates evidencing the
Shares duly endorsed in blank, or accompanied by valid stock powers duly
executed in blank, in proper form for transfer.

      1.2 PURCHASE PRICE. Subject to the adjustments set forth in this Article
I, the aggregate purchase price of the Shares shall be equal to * (the "CLOSING
PURCHASE PRICE"), plus the amount of the Upside Sharing Payment (as defined
herein), if any (collectively, the "PURCHASE PRICE").

      1.3 ADJUSTMENT TO THE PURCHASE PRICE. The Closing Purchase Price shall be:
(a) increased by the amount by which the Net Book Value (as defined herein)
exceeds *; or (b) reduced by the amount by which exceeds the Net Book Value. The
Net Book Value shall be the amount by which the aggregate consolidated assets of
the Company and its Subsidiaries exceeds the aggregate consolidated liabilities
of the Company and its Subsidiaries, all as determined and adjusted in
accordance with Section 1.5 below and as shown on the Closing Balance Sheet.


<PAGE>
                           "*SEE PAGE ONE OF EXHIBIT"

      1.4 MANNER OF PAYMENT OF THE PURCHASE PRICE. For purposes of the Closing,
the parties shall make a good-faith estimate of the Closing Purchase Price (the
"ESTIMATED CASH PAYMENT"), based upon the most recent ascertainable financial
information. At the Closing, Watson shall pay the Estimated Cash Payment to
Seller, by wire transfer to such account as Seller shall designate by written
notice delivered to Purchaser not later than two (2) business days prior to the
Closing. Following the Closing, the parties shall determine the final Closing
Purchase Price, taking into account the adjustments required pursuant to Section
1.3 and employing the procedures and criteria set forth in Sections 1.5 and 1.6.
If, based on the Closing Purchase Price as finally determined: (a) the Closing
Purchase Price exceeds the Estimated Cash Payment, Watson shall forthwith pay
the excess to Seller; or (b) the Estimated Cash Payment exceeds the Closing
Purchase Price, Seller shall forthwith pay the excess to Watson. Notwithstanding
anything to the contrary contained herein, if (x) the Company or any of its
Subsidiaries reverses any of the reserves set forth on the Interim Financial
Statements at any time from July 31, 1997 through the Closing Date where the
effect of such reversal would be to increase the Company's and its Subsidiaries'
consolidated net income; and (y) the Net Book Value, as calculated on the
Closing Balance Sheet, exceeds *, then the Net Book Value, as calculated on the
Closing Balance Sheet, shall be reduced by the amount of the increase in Net
Book Value resulting from such reversal and resultant increase in consolidated
net income; provided, however, that the Net Book Value shall not be reduced to
less than * based upon such reserve reversal.

      1.5 DETERMINATION OF NET BOOK VALUE. The Net Book Value shall be
determined from a statement of the consolidated assets and liabilities of the
Company and its Subsidiaries as of the close of business on the day next
preceding the Closing (the "CLOSING BALANCE SHEET"). The Closing Balance Sheet
shall be prepared by Seller, at Seller's expense. Except as otherwise provided
in this Section 1.5, the Closing Balance Sheet shall be prepared in accordance
with generally accepted accounting principles ("GAAP") applied in a manner
consistent with the accounting principles applied in the preparation of the
Financial Statements (as defined herein) and the Interim Financial Statements
(as defined herein) based upon the Company's historical accounting practices.
Notwithstanding anything to the contrary contained in this Article I, (a) the
Closing Balance Sheet shall contain pro rata accruals for accrued salaries,
wages and vacation pay with respect to all of the employees of the Company and
its Subsidiaries, utilities and like items; (b) assets and liabilities shall be
reflected without regard to materiality; (c) the Closing Balance Sheet shall be
prepared on the basis that the intercompany payable from the Company to Parent
has been converted to equity in accordance with Section 5.3(j) of this
Agreement; (d) for purposes of preparing the Closing Balance Sheet, the *.
Seller shall cause the Closing Balance Sheet to be delivered to Watson not later
than sixty (60) days after the Closing Date. Seller shall make available to
Watson and Watson's accountants its work papers used in connection with the
preparation of the Closing Balance Sheet.

1.6 DISPUTES REGARDING CLOSING BALANCE SHEET. Disputes with respect to the
Closing Balance Sheet shall be dealt with as follows:

      (a) Watson shall have sixty (60) days after receipt of the Closing Balance
Sheet from Seller (the "DISPUTE PERIOD") to dispute any of the elements of the
Closing Balance Sheet (a "DISPUTE"). If Watson does not give written notice of a
Dispute within the Dispute Period to Seller (a "DISPUTE NOTICE"), the Closing
Balance Sheet shall be deemed to have been accepted and agreed to by Watson in
the form in which it was delivered by Seller, and shall be final and binding
upon the parties hereto. If Watson has a Dispute, Watson shall give Seller a
Dispute 

                                       2

<PAGE>
                           "*SEE PAGE ONE OF EXHIBIT"

Notice within the Dispute Period, setting forth in reasonable detail the
elements and amounts with which it disagrees. Within thirty (30) days after
delivery of such Dispute Notice, the parties hereto shall attempt to resolve
such Dispute and agree in writing upon the final content of the disputed Closing
Balance Sheet.

      (b) If Watson and Seller are unable to resolve any Dispute within the
thirty (30) day period after Seller's receipt of a Dispute Notice, the New York
office of the certified public accounting firm of Arthur Andersen LLP (the
"ARBITRATING ACCOUNTANT") shall be engaged as arbitrator hereunder to settle
such Dispute as soon as practicable. In the event Arthur Andersen LLP is
unwilling or unable to serve as the Arbitrating Accountant, the parties hereto
shall select by mutual agreement another nationally recognized certified public
accounting firm, who is not rendering (and during the preceding two-year period
has not rendered) services to either Parent, Watson or any of their respective
affiliates, to serve as the Arbitrating Accountant. In connection with the
resolution of any Dispute, the Arbitrating Accountant shall have access to all
documents, records, work papers, facilities and personnel necessary to perform
its function as arbitrator. The arbitration before the Arbitrating Accountant
shall be conducted in accordance with the commercial arbitration rules of the
American Arbitration Association. The Arbitrating Accountant's award with
respect to any Dispute shall be final and binding upon the parties hereto, and
judgment may be entered on the award. Parent and Watson shall each pay one-half
of the fees and expenses of the Arbitrating Accountant with respect to any
Dispute.

      1.7 TIME AND PLACE OF CLOSING. Unless terminated earlier as provided in
Article VIII hereof, the transactions contemplated by this Agreement shall be
consummated (the "CLOSING") at 10:00 a.m., prevailing business time, at the
offices of D'Ancona & Pflaum, 30 North LaSalle, Suite 2900, Chicago, Illinois
60602 two (2) business days after all the conditions of Closing set forth in

                                       3

<PAGE>


Article V hereof are satisfied or waived, or on such other date, or at such
other place, as shall be agreed upon by Seller and Watson. The date on which the
Closing shall occur in accordance with the preceding sentence is referred to in
this Agreement as the "CLOSING DATE". If the Closing shall occur, it shall be
deemed to be effective as of 12:01 a.m., prevailing time at the place of Closing
on the Closing Date.

                                   ARTICLE II

                   REPRESENTATIONS AND WARRANTIES OF WATSON

      Watson represents and warrants to Seller that the statements contained in
this Article II are true and correct as of the date hereof (except as otherwise
noted), except as set forth in the disclosure statement delivered by Watson to
Seller concurrently herewith and identified as the "WATSON DISCLOSURE
STATEMENT." All exceptions noted in the Watson Disclosure Statement shall be
numbered to correspond to the applicable sections to which such exception
refers; provided, however, that any disclosure set forth on any particular
schedule shall be deemed disclosed in reference to all applicable schedules.

      2.1 EXISTENCE, GOOD STANDING, CORPORATE AUTHORITY. Watson is a corporation
duly incorporated, validly existing and in good standing under the laws of the
State of Nevada and has all requisite power and authority to (i) own or lease,
and operate its properties and assets and to carry on its business as now
conducted, except where the failure to have such power and authority would not
have a Watson Material Adverse Effect (as defined herein); (ii) enter into and
perform this Agreement and the other agreements executed in connection herewith
to which Watson is a party (collectively, the "WATSON ANCILLARY DOCUMENTS"); and
(iii) consummate the transactions contemplated hereby and thereby. For purposes
of this Agreement, (a) the term "MATERIAL ADVERSE EFFECT" when used with respect
to any Person (as defined herein) means (i) a material adverse effect on the
business, results of operations, assets, product pipeline or financial condition
of such Person and its Subsidiaries (as defined herein), if any, taken as a
whole, or (ii) a material impairment in the ability of such Person or its
Subsidiaries to perform any of their obligations under this Agreement or to
consummate the transactions contemplated hereby or under the Watson Ancillary
Documents or the Ancillary Documents (as defined herein), as the case may be,
(b) the term "SUBSIDIARY" when used with respect to any Person means any
corporation or other organization, whether incorporated or unincorporated, of
which (i) at least fifty percent (50%) of the securities or other interests
having by their terms ordinary voting power to elect a majority of the board of
directors or others performing similar functions with respect to such
corporation or other organization is directly or indirectly owned or controlled
by such Person or by any one or more of its Subsidiaries; or (ii) such Person or
any other Subsidiary of such Person is a general partner, it being understood
that representations and warranties of a Person concerning any former Subsidiary
of such Person shall be deemed to relate only to the periods during which such
former Subsidiary was a Subsidiary of such Person; and (c) the word "PERSON"
means an individual, a corporation, a partnership, a limited liability company,
an association, a trust or any other entity or organization, including a
government or political subdivision or any agency or instrumentality thereof, or
any affiliate (as that term is

                                       4

<PAGE>


defined in the Securities Exchange Act of 1934, as amended, and the rules and
regulations promulgated thereunder (the "EXCHANGE ACT")) of any of the
foregoing.

      2.2 AUTHORIZATION OF AGREEMENT AND OTHER DOCUMENTS. The execution and
delivery of this Agreement and the Watson Ancillary Documents and the
consummation by Watson of the transactions contemplated hereby and thereby have
been duly authorized by the Board of Directors of Watson and no other
proceedings on the part of Watson or its stockholders are necessary to authorize
the execution, delivery or performance of this Agreement or any Watson Ancillary
Document. This Agreement has been duly and validly executed and delivered and
is, and, as of the Closing Date, each of the Watson Ancillary Documents will be
duly and validly executed and delivered and will constitute, a valid and binding
obligation of Watson enforceable against Watson in accordance with its terms,
except to the extent that enforcement thereof may be limited by bankruptcy,
insolvency, reorganization, moratorium, fraudulent conveyance or other similar
laws affecting enforcement of creditors' rights generally, and by general
principles of equity (regardless of whether enforcement is considered in a
proceeding at law or in equity).

      2.3 NO VIOLATION. Neither the execution and delivery by Watson of this
Agreement or the Watson Ancillary Agreements, nor the consummation by Watson of
the transactions contemplated hereby and thereby in accordance with their
respective terms, will (a) violate or conflict with or result in a breach of any
provisions of the Articles of Incorporation or By-Laws of Watson; (b) contravene
or conflict with or constitute a violation of any provision of any law,
regulation, judgment, injunction, order or decree binding upon or applicable to
Watson, except for any of the foregoing matters which would not have a Watson
Material Adverse Effect; (c) violate, conflict with, result in a breach of any
provision of, constitute a default (or an event which, with notice or lapse of
time or both, would constitute a default) under, result in the termination, or
in a right of termination or cancellation of, accelerate the performance
required by, result in the triggering of any payment or other obligations
pursuant to, result in the creation of any lien, security interest, charge or
encumbrance upon any of the properties of Watson or any of its Subsidiaries
under, or result in being declared void, voidable, or without further binding
effect, any of the terms, conditions or provisions of any note, bond, mortgage,
indenture, deed of trust or any license, franchise, permit, lease, contract,
agreement or other instrument, commitment or obligation to which Watson or any
of its Subsidiaries is a party, or by which Watson or any of its Subsidiaries or
any of their respective properties is bound or affected, in each case, where
such violation, conflict, lien or breach would have a Watson Material Adverse
Effect; or (d) other than the filings under applicable federal, state and local
laws and regulations, or filings required under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976 and the expiration or early termination of all waiting
periods thereunder (the "HSR ACT") (collectively, the "REGULATORY FILINGS"),
require any consent, approval or authorization of, or declaration of, or
registration or filing with, any domestic governmental or regulatory authority,
the failure to obtain or make which would have a Watson Material Adverse Effect.

                                       5

<PAGE>


      2.4 NO BROKERS. Watson has not entered into any contract, arrangement or
understanding with any person or firm which may result in the obligation of
Parent, Seller, Watson or their respective Subsidiaries to pay any finder's fee,
brokerage or agent's commissions or other like payments in connection with the
negotiations leading to this Agreement or the consummation of the transactions
contemplated hereby, except that Watson has retained Bear, Stearns & Co. Inc. as
its financial advisor.

      2.5 ACCREDITED INVESTOR. Watson is an "accredited investor" within the
meaning of Rule 501(a) of Regulation D under the Securities Act of 1933, as
amended (the "SECURITIES ACT") and is acquiring the Shares for its own account
for investment and not with a view to, or for resale in connection with, any
"distribution" within the meaning of the Securities Act. Watson understands that
the Shares have not been registered under the Securities Act or any state
securities laws and are being transferred to Watson, in part, in reliance on the
foregoing representation.

      2.6 LITIGATION. There is no litigation or proceeding, in law or in equity,
and there are no proceedings or governmental investigations before any
commission or other administrative authority, pending or, to Watson's knowledge,
threatened against Watson or any of its Subsidiaries, which, if determined
adversely to Watson or its Subsidiaries, would reasonably be likely to have a
Watson Material Adverse Effect.

      2.7 FINANCING. Upon the terms and subject to the conditions of this
Agreement, Watson will have all funds necessary for the payment of the Closing
Purchase Price and anticipates having sufficient funds to pay the Upside Sharing
Payment.

      2.8 EFFECT ON AGREEMENT. There is no agreement or arrangement binding on
Watson or any of its Subsidiaries that would materially limit its ability to
develop, sell or distribute any of the Products (as defined herein) or run the
Distribution Business (as defined herein) as such Distribution Business existed
on July 31, 1997, assuming the Closing had occurred as of such date, other than,
in each case, limitations which affect the pharmaceutical industry generally or
limitations which arise due to Watson's allocation of its limited resources.
Watson believes that it currently has adequate resources to run the Distribution
Business and develop, sell and/or distribute the Products in a commercially
reasonable good faith manner.

      3.11 FINANCIAL STATEMENTS. The Disclosure Statement contains complete and
accurate copies of the audited consolidated balance sheets, statements of income
and retained earnings, statements of cash flows and notes to financial
statements (together with any supplementary information thereto) of the Company
and its Subsidiaries as of and for the years ended December 31, 1995 and 1996.
The financial statements described in the preceding sentence are hereinafter
referred to as the "FINANCIAL STATEMENTS". The Disclosure Statement also
contains complete and accurate copies of the unaudited consolidated balance
sheet and statement of income and retained earnings and unaudited statement of
cash flows of the Company and its Subsidiaries as of and for the seven month
period ended July 31, 1997. The financial statements described in the preceding
sentence are referred to herein as the "INTERIM FINANCIAL STATEMENTS". The
Financial Statements and the Interim Financial Statements present fairly, in all
material respects, the consolidated financial position of the Company and its
Subsidiaries as of the dates thereof and the consolidated results of operations
and cash flows of the Company and its Subsidiaries for the periods covered by
said statements, subject, in the case of the Interim Financial Statements, to
normal year end adjustments, all in accordance with GAAP applied on a consistent
basis, except as set forth in the notes to such Financial Statements and Interim
Financial Statements. The Disclosure Statement contains complete and correct
copies of all attorneys' responses to audit inquiry letters and all management
letters from the Company's and its Subsidiaries' independent certified public
accountants for the last three (3) fiscal years of the Company. Since January 1,
1994, there has been no material change in the Company's or its Subsidiaries'
accounting methods or principles, except (i) as described in the notes to the
Financial Statements or the Interim Financial Statements; and (ii) as provided
in the following sentence. Since July 31, 1997 through the date hereof, neither

      3.12 ACCOUNTS RECEIVABLES. To the knowledge of the Company, none of the
trade receivables and notes receivable which are reflected in the Financial
Statements or the Interim Financial Statements or which arose subsequent to July

trade receivables arose out of bona fide, arms-length transactions for the sale
of goods or performance of services, and to the Company's 

                                       12

<PAGE>
                           "*SEE PAGE ONE OF EXHIBIT"

knowledge, all such trade receivables and notes receivable are good and
collectible (or have been collected) in the ordinary course of business using
normal collection practices at the aggregate recorded amounts thereof, less the
amount of applicable reserves (i.e. rebates, returns or price adjustments),
customary charge backs, allowances for doubtful accounts and discounts. All such
reserves, charge backs, allowances for doubtful accounts and discounts, were and
are materially consistent in extent with reserves, charge backs, allowances for
doubtful accounts and discounts previously maintained by the Company in the
ordinary course of its business, subject to industry changes due to shelf
restocking or customer rebates. The Company reasonably believes that all
reserves, charge backs, allowances for doubtful accounts and discounts set forth
on the Financial Statements and the Interim Financial Statements are sufficient.

the Company's aggregate trade receivables or a material adverse change in the
aging thereof.

quality historically useable and/or saleable in the normal course of business,
except for immaterial items of Inventory or items of obsolete and slow-moving
material, substantially all of which have been written down to estimated net
realizable value on an item by item basis. None of such write-downs have had a
Company Material Adverse Effect. With the exception of items of below standard
quality which have been written down to their estimated net realizable value, no
material portion of the materials and/or workmanship comprising the Inventory is
defective. All Inventory reflected in the Financial Statements and the Interim
Financial Statements is valued at the lower of cost or market with cost
determined by the trailing average accounting method. Since July 31, 1997, there
has not been a material change in the level of the Inventory. All Inventory is,
and, to the knowledge of the Company, all material tools, dies, jigs, patterns,
molds, equipment, supplies and other materials used in the production of

take any actions outside the ordinary course of business *; or (ii) *.

      (c) The Upside Sharing Payment (as defined herein) shall reflect the net
profit (as calculated in the same manner as the calculation of Net Profit)

products included in the Distribution Business multiplied by the following
fraction, the numerator of which is equal to the number of units of such Product
or Distribution Business product, as the case may be, included in such bundled
sale multiplied by the standard invoice unit price thereof, and the denominator
of which is equal to the sum of the number of units of each product (including
the Products or any product sold through the Distribution Business) or service
included in such bundled sale multiplied by the respective standard invoice unit
price thereof.

      6.3 QUARTERLY REPORTING. From the Closing Date through the period that
Watson or any of its Subsidiaries sells * as a distributed (rather than a

provide Seller with a statement of accounting (the "QUARTERLY REPORT") which
shall set forth in full detail Watson's and its Subsidiaries' computation of Net
Profits relating to Watson's or any of its Subsidiaries' sale of * during the
calendar quarter recently ended. The Quarterly Report shall be accompanied by a
certificate of an executive officer of Watson certifying the amount of * sold by
Watson and its Subsidiaries for the period covered by such Quarterly Report.

      6.4  *PAYMENT ON*.

      (a) Together with the delivery of the Quarterly Report by Watson to
Seller, Watson shall pay Seller an amount equal to * of the Net Profit relating
to Watson's or any of its Subsidiaries' sale of * during the calendar quarter
covered by the Quarterly Report; provided, however, that, in lieu of the
foregoing *, until the earlier of the date upon which the * Payment (as defined
herein) has been paid in full or December 31, 1998, Watson or one of its
Subsidiaries shall pay Seller * of the Net Profit earned by Watson and its
Subsidiaries on the sale of * during the period beginning on the Closing Date
and ending on December 31, 1998. For purposes of this Agreement, the "*PAYMENT"

any amount of Net Profit earned by the Company or one of its Subsidiaries on the
sale of * during the period from the opening of business

                                       40

<PAGE>
                           "*SEE PAGE ONE OF EXHIBIT"

on August 11, 1997 through the Closing Date; and (ii) any amounts paid by Watson
or one of its Subsidiaries to Seller pursuant to the proviso at the end of the
first sentence of this Section 6.4(a) or Section 6.4(b)(ii) herein; and (iii)
amounts paid to Seller or Parent pursuant to Section 2.13 of the Contract
Manufacturing Agreement attached hereto as EXHIBIT B, but shall exclude the
amounts paid by Watson to Seller pursuant to Section 6.4(e) herein.

      (b) To the extent Watson, the Company or any of their respective
Subsidiaries actually receives any refund of the amounts described in Sections 6
and 9(a) of the * Agreement, or any other amounts from * due to the breach of
such agreement by * or due to purchase credits or similar adjustments (other
than credits for shortages of goods or damaged goods), whether such amounts are
received, or relate to events occurring, before or after the Closing, Watson
agrees that such refund or payment shall be distributed as follows: (i) first,
to pay any and all out-of-pocket costs and expenses incurred by Watson, the
Company or their respective Subsidiaries, or by Parent and its Subsidiaries, at
the request of Watson, to collect such refund or payment, including, without
limitation, all out-of-pocket legal expenses and court costs; (ii) second, if
the event that gave rise to such breach or credit occurred on or prior to
December 31, 1998, to Seller in an amount up to the unpaid portion of the *
Payment as of the date Watson or any of its Subsidiaries actually receives such
refund or payment; and (iii) finally, any remainder of such refund or payment
shall be shared by the Company and Seller as follows: *. Notwithstanding the
foregoing, the amounts described in Section 6.4(e) hereof shall be paid by
Watson or one of its Subsidiaries to Seller.

      (c) Within a reasonable time after there are no limitations (legal or
otherwise) on the Company's or its Subsidiaries' ability to sell * under its own
ANDA, or such earlier date as Watson determines, in its sole and absolute
discretion, Watson shall cause the Company to deliver a termination notice to *
pursuant to Section 4 of the * Agreement.

      (d) Watson and its Subsidiaries shall sell * at a price to be determined
by Watson in its sole and absolute discretion. Until such time as Watson or one
of its Subsidiaries begins to sell * as a manufactured product, Watson and its
Subsidiaries agree to use commercially reasonable good faith efforts to market
and sell *, unless it becomes commercially unfeasible for Watson or its
Subsidiaries to continue to market and sell *. Such efforts shall be used
without regard to the payments to be made pursuant to this Section 6.4. Payments
to Seller based upon the Net Profit earned on the sale of * shall reflect the
net profit (as calculated in the same manner as the calculation of Net Profit)
received by Watson or its Subsidiaries on the bundled sale of products including
* multiplied by the following fraction, the numerator of which is equal to the
number of units of * multiplied by the standard invoice unit price thereof, and
the denominator of which is equal to the sum of the number of units of each
product (including *) or service included in such bundled sale multiplied by the
respective standard invoice unit price thereof.

                           "*SEE PAGE ONE OF EXHIBIT"

      (e) To the extent that Watson or one of its Subsidiaries actually receives
any amounts from * relating to purchase credits on any units of * sold by the
Company or its Subsidiaries and such purchase credits relate in whole or in part
to the period of time prior to *, Watson or one of its Subsidiaries shall pay
such amount of the credits which relate to the sale of * made by the Company or
its Subsidiaries prior to * to Seller within ten (10) days after its receipt of
such amount.

      6.5  UPSIDE SHARING PAYMENT.

      (a) Subject to the provisions of Section 6.6 herein, on or prior to *,
Watson shall provide Seller with a statement of accounting (the "UPSIDE SHARING
REPORT") which shall set forth in full detail the computation of (i) the Net
Profit on Watson's and its Subsidiaries' sale of the Products during calendar
year *; and (ii) the Distribution Net Profit during calendar year * (the sum of
(i) and (ii) being collectively referred to herein as the "UPSIDE NET PROFITS").
The Upside Sharing Report shall be accompanied by a certificate of an executive
officer of Watson certifying the amount of the Upside Net Profits.

      (b) Subject to the provisions of Section 6.6 herein, together with the
delivery of the Upside Sharing Report by Watson to Seller, Watson shall pay to
Seller an amount equal to the following (the "UPSIDE SHARING PAYMENT") provided,
however, that the Upside Sharing Payment shall not exceed $*:

           *

      6.6  SALES AND ACQUISITIONS.

      (a) Except for acquisitions which qualify for the treatment under Section
6.6(b) herein: if (i) Watson or any of its Subsidiaries (A)(I) acquires any
pharmaceutical distribution business or

                                       42

<PAGE>
                           "*SEE PAGE ONE OF EXHIBIT"

any portion thereof in one or a series of related transactions; or (II) acquires
any entity which is in the pharmaceutical distribution business in one or a
series of related transactions and such distribution business is acquired by
Watson or any of its Subsidiaries in connection with such acquisition, and, in
each of (I) or (II) above, the aggregate net sales of the distribution business
acquired exceeds $* during the twelve month period immediately prior to such
acquisition, excluding the net sales of any products acquired which are or will
be Watson Products; or (ii) Watson sells to an unaffiliated third party all or
substantially all of the Distribution Business in one or a series of related
transactions (each of (i) and (ii) being collectively referred to herein as a
"SALE EVENT"), then, except as provided below in this Section 6.6(a), for
purposes of calculating the Upside Net Profit, the Distribution Net Profits
derived by Watson and its Subsidiaries from the Distribution Business during
calendar year * shall be deemed to be equal to (x) if the Sale Event occurs on
or after January 1, 1998, the Distribution Net Profits derived by Watson and its
Subsidiaries from the Distribution Business during the twelve month period
ending on the last day of the calendar month immediately preceding such Sale
Event; or (y) if the Sale Event occurs prior to January 1, 1998, the
Distribution Net Profits derived by Watson and its Subsidiaries from the
Distribution Business during calendar year 1997 for the period beginning on
January 1, 1997 and ending on the day immediately preceding the closing date of
the Sale Event multiplied by the following fraction, the numerator of which is
equal to 365 and the denominator of which is equal to the number of days between
January 1, 1997 and the day immediately preceding the closing date of the Sale
Event. Notwithstanding the foregoing, if the net profits (calculated in the same
manner as the calculation of Distribution Net Profits) of any distribution
business acquired by Watson or any of its Subsidiaries pursuant to Section
6.6(a)(i) is not less than zero for the twelve month period ending on the date
of the most recent financial statements referenced in the principal acquisition
agreement relating to Watson's or any of its Subsidiaries' acquisition of such
distribution business, then, in lieu of the foregoing calculation of
Distribution Net Profits, Watson may, in its sole discretion, elect to calculate
Distribution Net Profits derived by Watson and its Subsidiaries from the
Distribution Business during calendar year 1999 in accordance with the
provisions of Section 6.5 hereof. Watson must exercise such election by
delivering written notice to Parent on or prior to the closing date of the
acquisition of such distribution business. If Watson or one of its Subsidiaries
acquires any entity described in Section 6.6(a)(i)(A) above, with net sales
(excluding sales attributable to Watson Products) equal to or less than $*
during the twelve month period immediately prior to such acquisition, the net
profits (calculated in the same manner as the calculation of Distribution Net
Profits) derived by Watson and its Subsidiaries from such acquired business
during calendar year * shall be included in the calculation of Distribution Net
Profits.

      (b) If (i) Watson or any of its Subsidiaries acquires any pharmaceutical
company primarily engaged in the manufacture and sale of pharmaceutical products
(an "ACQUIRED COMPANY"); and (ii) the Acquired Company distributes (but not
manufactures) five or less pharmaceutical products at the time of such
acquisition (the "ACQUIRED DISTRIBUTED Products"), then, for purposes of
calculating Upside Net Profits, the Distribution Net Profits derived by Watson
and its Subsidiaries from the sale of the Acquired Distributed Products during
calendar year * shall be deemed to be equal to the sum of (x) the Distribution
Net Profits derived by

                                       43

<PAGE>
                           "*SEE PAGE ONE OF EXHIBIT"

Watson and its Subsidiaries from the sale of the Acquired Distributed Products
during the twelve month period ending on the last day of the calendar month
immediately preceding the closing date of the acquisition of the Acquired
Company by Watson or any of its Subsidiaries; plus (y) the difference between
(A) the Distribution Net Profits derived by Watson and its Subsidiaries from the
sale of the Acquired Distributed Products during calendar year *; and (B) the
sum of (I) the Distribution Net Profits derived by Watson and its Subsidiaries
from the sale of the Acquired Distributed Products during the twelve month
period ending on the last day of the calendar month immediately preceding the
closing date of the acquisition of the Acquired Company by Watson or any of its
Subsidiaries; plus (II) the Distribution Net Profits derived by the Acquired
Company from the sale of the Acquired Distributed Products during the twelve
month period ending on the last day of the calendar month immediately preceding
the closing date of the acquisition of the Acquired Company by Watson or any of
its Subsidiaries; provided, however, that the amount calculated pursuant to this
subparagraph (y) shall not be less than zero.

      (c) If Watson or any of its Subsidiaries disposes of any Product at any
time on or prior to December 31, *, (i) all Net Profits received from the
commercial sale of such Product during calendar year * shall be excluded from
the calculation of Upside Net Profits; and (ii) as consideration for the
exclusion of the Net Profits derived from the commercial sale of such Product
from the calculation of Upside Net Profits, Watson or one of its Subsidiaries
shall pay Seller an amount in cash equal to one-half (1/2) of any and all
consideration received by Watson and its Subsidiaries in connection with such
sale, including, without limitation, one-half (1/2) of the reasonably estimated
present value (using an 8% discount factor) of any future payments (including
royalty payments) to be received by Watson or any of its Subsidiaries in
connection with the disposition of such Product and the fair market value of the
securities or other non-cash consideration received by Watson or its
Subsidiaries, but after payment of all reasonable out-of-pocket costs and
expenses related to such sale, including, without limitation, any legal,
accounting and investment banking fees; provided, however, that if the closing
of the disposition of such Product occurs at any time prior to December 31, *,
in lieu of receiving the amounts set forth in Section 6.6(c)(ii), Parent may
elect to include the Net Profits derived from the sale of such Product during
the twelve month period ending on the last day of the calendar month immediately
preceding the closing date of the disposition of such Product in the calculation
of the Upside Net Profits. Parent must exercise such election by delivering
written notice to Watson on or prior to thirty (30) days after its receipt of
the Transfer Notice (as defined herein) with respect to the transaction
consummated by Watson or any of its Subsidiaries pursuant to this Section
6.6(c).

      (d) If Watson or any of its Subsidiaries acquires any company which is
selling one or more of the Products or if Watson or any of its Subsidiaries
acquires the right to sell one or more of the Products from an unaffiliated
third party (each, a "PRODUCT ACQUISITION") and Watson or one of its
Subsidiaries is selling such Product as of the date of the Product Acquisition,
for purposes of calculating the Upside Net Profits, the Net Profit derived from
the sale of such Product by Watson and its Subsidiaries during calendar year *
shall be equal to the Net Profit derived by Watson and its Subsidiaries from the
sale of such Product during calendar year * multiplied by the following
fraction: the numerator of which is equal to the Net Profit derived by

                                       44

<PAGE>
                           "*SEE PAGE ONE OF EXHIBIT"

Watson and its Subsidiaries from the sale of such Product for the twelve month
period ending on the day immediately preceding the closing of the Product
Acquisition, and the denominator of which is equal to the sum of (i) the Net
Profit derived by Watson and its Subsidiaries from the sale of such Product for
the twelve month period ending on the day immediately preceding the closing of
the Product Acquisition; plus (ii) the Net Profit derived by the Person selling
the Product to Watson or one of its Subsidiaries (the "PRODUCT SELLING ENTITY")
from the sale of such Product for the twelve month period ending on the day
immediately preceding the closing of the Product Acquisition. If either Watson
or any of its Subsidiaries, on the one hand, or the Product Selling Entity, on
the other hand, has not been selling such Product for the entire twelve month
period referenced above, then the twelve month period referenced above shall be
revised to only include the period of time that each of Watson or any of its
Subsidiaries, on the one hand, or the Product Selling Entity, on the other hand,
has been selling such Product. The Net Profit derived by each of Watson or any
of its Subsidiaries, on the one hand, or the Product Selling Entity, on the
other hand, from the sale of such Product shall be appropriately adjusted to
exclude the Net Profits earned by Watson or any of its Subsidiaries, on the one
hand, or the Product Selling Entity, on the other hand, on the sale of the
Product due to initial new product launch stocking orders.

      (e) Except as otherwise specified in this Section 6.6, all Net Profit
earned by Watson or its Subsidiaries from the sale of the Products during
calendar year * and all Distribution Net Profit earned by Watson and its
Subsidiaries from the sale of products included in the definition of
Distribution Business during calendar year * shall be included in the
calculation of Upside Net Profits pursuant to Section 6.5.

      (f) Watson agrees to provide Parent with written notice of the occurrence
of any of the events set forth in this Section 6.6 within fifteen (15) days
after the closing of such event (the "TRANSACTION NOTICE").

      (g) At any time on or prior to December 31, *, Watson and its Subsidiaries
agree not to dispose of any Product at less than such Product's fair market
value or, in connection with the acquisition of any business or product, grant
any significant royalty on sales of any of the Products, if the effect of such
disposition or acquisition would cause (i) Watson or one of its Subsidiaries to
obtain an asset or right of material value; and (ii) a material decrease or a
potentially material decrease to the anticipated value of the Upside Sharing
Payment calculated as of the date of such disposition or acquisition, as the
case may be; provided, however, that Watson or its Subsidiaries may enter into
the transactions described in Section 6.6(c) without complying with the
provisions of this Section 6.6(g).

      6.7 DISPUTES REGARDING ARTICLE VI PAYMENTS. Disputes with respect to
payments made pursuant to this Article VI shall be dealt with as follows:

      (a) Seller shall have until December 31, * (the "UPSIDE DISPUTE Period")
to dispute the amount of the Upside Sharing Payment (an "UPSIDE DISPUTE"). If
Seller does not give written notice of an Upside Dispute within the Upside
Dispute Period to Watson (an "UPSIDE DISPUTE

                                       45

NOTICE"), the amount of such payment shall be deemed to have been accepted and
agreed to by Seller and Parent and shall be final and binding upon the parties
hereto. If Seller has an Upside Dispute, Seller shall give Watson an Upside
Dispute Notice within the Upside Dispute Period, setting forth in reasonable
detail the elements and amounts with which it disagrees. Within thirty (30) days
after delivery of such Upside Dispute Notice, the parties hereto shall attempt
to resolve such Upside Dispute and agree in writing upon the final amount of the
disputed payment.

      (b) If Watson and Seller are unable to resolve any Dispute within the
thirty (30) day period after Watson's receipt of an Upside Dispute Notice, the
Arbitrating Accountant shall be engaged as arbitrator hereunder to settle such
Upside Dispute as soon as practicable. In the event Arthur Andersen LLP is
unwilling or unable to serve as the Arbitrating Accountant, the parties hereto
shall select by mutual agreement another nationally recognized certified public
accounting firm, who is not rendering (and during the preceding two-year period
has not rendered) services to either Parent, Watson or any of their respective
affiliates, to serve as the Arbitrating Accountant. In connection with the
resolution of any Upside Dispute, the Arbitrating Accountant shall have access
to all documents, records, work papers, facilities and personnel necessary to
perform its function as arbitrator. The arbitration before the Arbitrating
Accountant shall be conducted in accordance with the commercial arbitration
rules of the American Arbitration Association. The Arbitrating Accountant's
award with respect to any Upside Dispute shall be final and binding upon the
parties hereto, and judgment may be entered on the award. Parent and Watson
shall each pay one-half of the fees and expenses of the Arbitrating Accountant
with respect to any Upside Dispute.

      (c) Any dispute with respect to a payment made pursuant to Section 6.4
shall be handled in the same manner as provided in subparagraphs (a) and (b)
above; provided, however, that Seller shall have a period of three years from
the receipt of such payment to dispute the amount of each such payment.
Notwithstanding the foregoing, once Parent has directly or indirectly reviewed
Watson's or any of its Subsidiaries' records relating to the calculation of Net
Profits on the sale of * for a specific time period, no dispute shall be made by
Parent or Seller relating to any payment made pursuant to Section 6.4 with
respect to any time period prior to such review, except for any disputes made in
connection with such review.

      (d) Any payments due by a party hereto to any other party hereto pursuant
to this Section 6.7 shall be payable within five business days of the final
resolution of any dispute, with interest accruing (i) from the date such dispute
was made for disputes under Section 6.4 at a rate equal to LIBOR plus 1 1/2% per
annum; and (ii) from the date such payment is due for disputes under Section 6.5
at a rate equal to LIBOR plus 1 1/2% per annum.

      6.8 RECORDS: INSPECTION OF RECORDS. Watson and its Subsidiaries shall each
maintain complete and accurate books and records of account relating to the sale
of products in sufficient detail to permit an accurate calculation of Watson's
and its Subsidiaries' Net Profit on the sale of Products and the calculation of
the Distribution Net Profits. Seller shall have the right at any time while
payments are being made by Watson to Seller pursuant to the terms of this
Article VI and

                                       46

<PAGE>


for one year thereafter to examine the relevant books and records of Watson and
its Subsidiaries relating to the sale of their products during normal business
hours and upon reasonable advance written notice to verify that appropriate
accounting and payments have been made by Watson to Seller under this Agreement.
Watson shall cooperate with Seller and Parent with respect to all reasonable
requests made by Seller or Parent with respect to such inspection.

      6.9 INTELLECTUAL PROPERTY RIGHTS. Seller and Parent recognize and agree
that, they shall not acquire any intellectual or other property rights in the
Products or in the ANDAs relative to the Products. Seller and Parent hereby
acknowledge that they do not have, and shall not acquire, any interest in any of
Watson's or any of its Subsidiaries' trademarks or trade names unless otherwise
expressly agreed. Additionally, Parent and Seller shall not use and shall not
license or permit any third party to use, any name, slogan, logo or trademark
which is similar or deceptively similar to any of the names or trademarks used
in connection with the business of the Company or any of its Subsidiaries.

      6.10 CONFIDENTIAL INFORMATION. During the period in which Watson is
required to make payments to Seller pursuant to this Article VI and for one year
thereafter, each party shall keep confidential and not disclose to others or use
for any purpose, other than as authorized by this Agreement, all "Confidential
Information" of the other party. For purposes of this Agreement, the term
"CONFIDENTIAL INFORMATION" means all know-how, trade secrets, formulae, data,
inventions, technology and other information, including financial information,
related to the manufacture, sale or marketing of the Products. The restrictions
of this Section shall not apply to any Confidential Information which (a) is or
becomes public knowledge through no fault of the recipient; (b) is received from
a third party having the lawful right to disclose the information; (c) is
required by law to be disclosed; or (d) is required to be disclosed in
connection with any applications filed with the FDA for approval to market the
Products. Additionally, Parent and Seller agree not to communicate or divulge
to, or use for the benefit of, any person, firm or corporation other than
Watson, its agents and representatives, any of the Company's or its
Subsidiaries' confidential information relating to the business conducted by the
Company or any of its Subsidiaries.

      6.11 INSPECTION OF RECORDS. Parent and Seller, on the one hand, and
Watson, on the other hand, and their respective affiliates, shall each retain
and make their respective books and records (including expired insurance
policies and work papers in the possession of their respective accountants) with
respect to the Company and its Subsidiaries available for inspection by the
other party, or by its duly accredited representatives, for reasonable business
purposes at all reasonable times during normal business hours, for a seven (7)
year period after the Closing Date, with respect to all transactions of the
Company and its Subsidiaries occurring prior to and relating to the Closing, and
the historical financial condition, assets, liabilities, operations and cash
flows of the Company and its Subsidiaries. As used in this Section 6.11, the
right of inspection includes the right to make extracts or copies. The
representatives of a party inspecting the records of the other party shall be
reasonably satisfactory to the other party.

                                       47

<PAGE>


      6.12 HIRING AWAY EMPLOYEES. For a period of two (2) years from the Closing
Date, Parent and Seller shall not, and shall cause its employees and agents to
not, solicit for hire any salaried, technical or professional employees,
representatives or agents of the Company or any of its Subsidiaries. .

      6.13 THIRD PARTY CLAIMS. The parties shall cooperate with each other with
respect to the defense of any claims or litigation made or commenced by third
parties subsequent to the Closing Date which are not subject to the
indemnification provisions contained in Article VII, provided that the party
requesting cooperation shall reimburse the other party for the other party's
reasonable out-of-pocket costs and expenses of furnishing such cooperation.

      6.14 FURTHER ASSURANCES. The parties shall execute such further documents,
and perform such further acts, as may be necessary to transfer and convey the
Shares to Watson on the terms herein contained and to otherwise comply with the
terms of this Agreement.

      6.15 INJUNCTIVE RELIEF. Parent and Seller specifically recognize that any
breach of Sections 6.9, 6.10 or 6.12 will cause irreparable injury to Watson and
that actual damages may be difficult to ascertain, and in any event, may be
inadequate. Accordingly (and without limiting the availability of legal or
equitable, including injunctive, remedies under any other provisions of this
Agreement), Seller and Parent agree that in the event of any such breach, Watson
shall be entitled to injunctive relief in addition to such other legal and
equitable remedies that may be available.

      6.16 EMPLOYEE BENEFIT PLANS. In the event that Watson terminates any Plan
in which any employees or former employees of the Company (and their spouses,
dependents and beneficiaries) participate, then such employees and former
employees (and their spouses, dependents and beneficiaries) shall immediately
become eligible to participate in any comparable employee benefit plan or
program available to Watson's similarly-situated employees (and their spouses,
dependents and beneficiaries) upon terms and conditions which are no less
favorable than those afforded Watson's similarly-situated employees (and their
spouses, dependents and beneficiaries). Such employees and former employees
shall receive credit for their service with the Company (including service with
any predecessor company to the extent credited under Company plans) for purposes
of determining their eligibility to participate, vesting and eligibility for
benefits under such employee benefit plans and programs of Watson. Further, with
respect to any of Watson's health and dental care plans in which the Company's
employees or former employees (and their spouses, dependents and beneficiaries)
become entitled to participate in pursuant to this Section 6.16, Watson agrees
that such individuals shall be entitled to so participate without regard to any
applicable waiting periods and any limitations on pre-existing conditions.

      In addition to the foregoing, Watson agrees that, in accordance with the
terms of the Company's severance and retention plans, programs and policies (or
in accordance with the terms of any replacement severance and retention plans,
programs or policies provided by Watson), all of which are listed on the
Disclosure Statement, Watson shall provide all severance and retention

                                       48

<PAGE>


benefits to all employees and former employees of the Company who are or who
become entitled to such benefits prior or subsequent to the Closing.

      6.17 PARENT EMPLOYEE STORE. For a period of five years from the Closing
Date (the "INITIAL TERM"), the Company agrees to continue to supply Parent's
employee store with over-the-counter products for the Company's cost of such
products plus ten percent (10%). The Initial Term shall automatically renew for
successive one year periods unless either party notifies the other party of its
desire to terminate the obligations set forth in this Section 6.17 at least
ninety (90) days prior to the expiration of the Initial Term or any renewal term
thereof.

                                   ARTICLE VII

                                 INDEMNIFICATION

      7.1 GENERAL. From and after the Closing, subject to the limitations set
forth in Section 7.5, the parties shall indemnify each other as provided in this
Article VII. For purposes of this Article VII, each party shall be deemed to
have remade all of its representations and warranties contained in this
Agreement at the Closing with the same effect as if originally made at the
Closing; provided, however, that the Watson Disclosure Statement and the
Disclosure Statement may be updated at the Closing by Watson and Seller, as the
case may be, and, except as otherwise provided in this Article VII, no indemnity
shall be provided hereunder with respect to the matters set forth therein. No
disclosure contained in the updated Watson Disclosure Statement or the
Disclosure Statement, as the case may be, shall be deemed a waiver of Watson's
or Seller's and Parent's representations and warranties made on the date hereof
with respect to the conditions to closing set forth in Sections 5.2(c) and
5.3(d) hereof.

      7.2 CERTAIN DEFINITIONS. As used in this Article VII, the following terms

losses, fines, penalties, damages, costs and expenses, including, without
limitation, reasonable fees and expenses of attorneys, accountants and other
professionals, actually sustained or incurred by an Indemnified Party in
connection with the defense or investigation of any claim (after giving effect
to any insurance proceeds actually received by an Indemnified Party).

           (b) "INDEMNIFIED PARTY" shall mean a party hereto who is entitled to
indemnification from another party hereto pursuant to this Article VII.

           (c) "INDEMNIFYING PARTY" shall mean a party hereto who is required to
provide indemnification under this Article VII to another party hereto.

                                       49

<PAGE>


           (d) "THIRD PARTY CLAIMS" shall mean any claims for Damages which are
asserted or threatened by a party other than the parties hereto, their
successors and permitted assigns, against any Indemnified Party or to which an
Indemnified Party is subject.

      7.3 SELLER'S INDEMNIFICATION OBLIGATIONS. Subject to the terms of Section
7.5, Seller and Parent, jointly and severally, and their respective successors
and assigns, shall indemnify, save and keep Watson, the Company, each of their
respective Subsidiaries and their respective successors and permitted assigns
(each a "WATSON INDEMNITEE" and collectively the "WATSON INDEMNITEES") harmless
against and from all Damages sustained or incurred by any Watson Indemnitee, as
a result of or arising out of: (a) any inaccuracy in or breach of any
representation and warranty made by Seller or Parent to Watson herein or in any
Ancillary Document; (b) any breach by Seller or Parent of, or failure of Seller
or Parent to comply with, any of the covenants or obligations under this
Agreement or the Ancillary Documents to be performed by Seller or Parent
(including, without limitation, Seller's and Parent's obligations under this
Article VII); and (c) without being limited by the foregoing paragraphs (a) and
(b), and without regard to whether any one or more of the items listed in this
subparagraph (c) may be disclosed in the Disclosure Statement or otherwise known
to Watson or any of its Subsidiaries as of the date hereof or the Closing Date,
(i) the Company's or its Subsidiaries ownership of the capital stock of Caribe
and the property located at Monroe, North Carolina which was owned by Chelsea
Laboratories, Inc., including, without limitation, any Damages caused by the
violation of any Environmental Law at such facilities or the presence or release
of any Hazardous Materials upon, about or beneath such facilities; (ii) any item
which should have been disclosed on the Disclosure Statement as of the Closing
Date in response to the representations and warranties set forth in Section 3.20
herein; and (iii) without being limited by subparagraph (ii) above, each of the
items disclosed on Schedules 3.8(d) and 3.20 of the Disclosure Statement and
each of the items described in the audit response letters attached as exhibits
to Schedule 3.11 of the Disclosure Statement; provided, however, that after the
Closing Date, Watson and the Company shall bear all liability for the item

entered into by the Company with the Department of Defense.

      7.4 WATSON'S INDEMNIFICATION OBLIGATIONS. Subject to the terms of Section
7.5, Watson shall indemnify, save and keep Parent and Seller and their
respective successors and permitted assigns ("SELLER INDEMNITEES"), forever

any Watson Ancillary Document; and (b) any breach by Watson of, or failure by

<PAGE>
                           "*SEE PAGE ONE OF EXHIBIT"

that the representations and warranties contained in Section 3.9 shall survive
the Closing until the expiration of the applicable statute of limitations (the
"SURVIVAL PERIOD"). A claim by a Watson Indemnitee or a Seller Indemnitee for
indemnification under this Article VII must be asserted within the applicable
Survival Period.

           (b) (i) the Watson Indemnitees shall only be entitled to
indemnification pursuant to Section 7.3 hereof once the Watson Indemnitees'
aggregate claims for indemnification exceed $*, but after such claims exceed
such amount, the Watson Indemnitees shall be entitled to seek indemnification
for all indemnification claims from the first dollar of Damages; and (ii) the
indemnification obligations of Parent and Seller pursuant to Section 7.3 hereof
shall be limited to an amount equal to $* in the aggregate.

           (c) (i) the Seller Indemnitees shall only be entitled to
indemnification pursuant to Section 7.4 hereof once the Seller Indemnitees'
aggregate claims for indemnification exceed $*, but after such claims exceed
such amount, the Seller Indemnitees shall be entitled to seek indemnification
for all indemnification claims from the first dollar of Damages; and (ii) the
indemnification obligations of Watson pursuant to Section 7.4 hereof shall be
limited to an amount equal to $* in the aggregate.

           (d) Notwithstanding anything to the contrary contained herein, the
limitations on Seller's and Parent's indemnification obligations contained in
this Section 7.5, including the time limitations contained in Section 7.5(a)
hereof, shall not apply to a claim for indemnification by a Watson Indemnitee
pursuant to Section 7.3(c) hereof, which claims may be brought by a Watson
Indemnitee against Seller or Parent at any time after the date hereof.

      7.6 COOPERATION. Subject to the provisions of Section 7.8, the
Indemnifying Party shall have the right, at its own expense, to participate in
the defense of any Third Party Claim, and if said right is exercised, the
parties shall cooperate in the investigation and defense of said Third Party
Claim. Watson and its Subsidiaries shall take all reasonable directions from
Parent relating to any claim made with respect to Caribe or the Monroe, North
Carolina facility previously owned by Chelsea Laboratories, Inc., at Parent's
sole cost and expense.

      7.7 SUBROGATION. The Indemnifying Party shall not be entitled to require
that any action be brought against any other person before action is brought
against it hereunder by the Indemnified Party and shall not be subrogated to any
right of action until it has paid in full or successfully defended against the
Third Party Claim for which indemnification is sought.

      7.8  INDEMNIFICATION CLAIMS PROCEDURES.

           (a) Promptly following the receipt of notice by the Watson
Indemnitees of a Third Party Claim which the Watson Indemnitees believe may
result in a demand for indemnification pursuant to this Article VII, Watson
shall notify Seller and Parent of such claim. Promptly following the receipt by
a Seller Indemnitee of notice of a Third Party Claim which

                                       51

<PAGE>


such Seller Indemnitee believes may result in a demand for indemnification
pursuant to this Article VII, such Seller Indemnitee shall notify Watson of such
claim. The failure to give such notice shall not relieve the Indemnifying Party
of its obligations under this Agreement except to the extent that the
Indemnifying Party is substantially prejudiced as a result of the failure to
give such notice. Within fifteen (15) business days after receipt of the notice
by the Indemnifying Party pursuant to the preceding sentence, the Indemnifying
Party shall notify the Indemnified Party whether it elects to control the
defense of the Third Party Claim. If the Indemnifying Party elects to undertake
the defense of such Third Party Claim, it shall do so at its own expense with
counsel of its own choosing and it shall acknowledge in writing without
qualification its indemnification obligations as provided in this Agreement to
the Indemnified Party as to such Third Party Claim. If the Indemnifying Party
elects not to defend the Third Party Claim or fails to pursue such Third Party
Claim diligently, the Indemnified Party shall have the right to undertake,
conduct and control the defense of such Third Party Claim through counsel of its
own choosing and the Indemnifying Party shall be entitled to participate in (but
not control) the defense of such Third Party Claim, with its counsel and at its
expense. The party that litigates or contests the Third Party Claim shall keep
the other party fully advised of the progress and disposition of such claim.

      (b) In the event the Indemnifying Party elects not to undertake the
defense of the Third Party Claim or fails to pursue diligently the defense of
such a claim and the Indemnified Party litigates or otherwise contests or
settles the Third Party Claim, then, provided that a final determination has
been made that the Indemnified Party is entitled to indemnification hereunder,
the Indemnifying Party shall promptly reimburse the Indemnified Party for all
amounts paid to settle such claim or all amounts paid in satisfaction of a
judgment against the Indemnified Party in contesting such claim and in providing
its right to indemnification hereunder, all in accordance with the provisions of
this Article VII. Notwithstanding the foregoing, no settlement of any Third
Party Claim without the prior written consent of the Indemnifying Party shall be
determinative of the validity of any claim that the Indemnified Party is
entitled to indemnification hereunder.

      (c) No Third Party Claim will be settled by the Indemnifying Party without
the prior written consent of the Indemnified Party, which consent will not be
unreasonably withheld; provided, however, that if such claim asserts that the
Indemnifying Party is jointly and severally liable and the Indemnified Party
shall be fully released from all liability relating to such Third Party Claim in
connection with such settlement, the Indemnifying Party shall not be required to
obtain the consent of the Indemnified Party. If, however, the Indemnified Party
refuses to consent to a bona fide offered settlement which the Indemnifying
Party wishes to accept, the Indemnified Party may continue to pursue such Third
Party Claim free of any participation by the Indemnifying Party, at the sole
expense of the Indemnified Party. In such event, the Indemnifying Party shall
pay to the Indemnified Party the amount of the offer of settlement which the
Indemnified Party refused to accept, plus the reasonable costs and expenses
incurred by the Indemnified Party prior to the date the Indemnifying Party
notifies the Indemnified Party of the offer of settlement, all in accordance
with the terms of this Article VII, and, upon the payment or receipt of such
amount, as the case may be, the Indemnifying Party shall have no further
liability with respect to such Third Party Claim. The Indemnifying Party shall
be entitled to

                                       52

<PAGE>


recover from the Indemnified Party any additional expenses incurred by such
Indemnifying Party as a result of the decision of the Indemnified Party to
pursue the matter.

                                   TERMINATION

      8.1 TERMINATION BY MUTUAL CONSENT. This Agreement may be terminated and
the transactions contemplated hereby may be abandoned at any time prior to the
Closing Date by the mutual consent of Watson, on the one hand, and Seller and
Parent, on the other hand.

      8.2 TERMINATION BY EITHER PARTY. This Agreement and the transaction
contemplated hereby may be terminated at any time prior to the Closing by either
party if (a) the Closing shall not have occurred at or before 11:59 p.m. on
November 30, 1997; provided, however, that the right to terminate this Agreement
under this Section 8.2(a) shall not be available to any party whose failure to
fulfill any material obligation under this Agreement has been the cause of or
resulted in the failure of the Closing to occur on or prior to the aforesaid
date; (b) a court of competent jurisdiction or a governmental, regulatory or
administrative agency or commission shall have issued an order, decree or ruling
or taken any other action either (i) permanently restraining, enjoining or
otherwise prohibiting the transactions contemplated by this Agreement; or (ii)
compelling Watson, the Company or any of their respective Subsidiaries to
dispose of or hold separate all or a material portion of the respective
businesses or assets of Watson, the Company or their respective Subsidiaries or
sell or license any material product of Watson, the Company or their respective
Subsidiaries, and such order, decree, ruling or other action shall have become
final and non-appealable.

      8.3 TERMINATION BY THE COMPANY. This Agreement may be terminated and the
transactions contemplated hereby may be abandoned at any time prior to the
Closing Date by Seller and Parent if (a) there has been a breach by Watson of
any representation or warranty contained in this Agreement which would have a
Watson Material Adverse Effect; or (b) there has been a breach of any of the
covenants or agreements set forth in this Agreement on the part of Watson which
would have a Watson Material Adverse Effect, and which breach is not curable or,
if curable, is not cured within 30 days after written notice of such breach is
given by Seller to Watson.

      8.4 TERMINATION BY WATSON. This Agreement may be terminated and the
transactions contemplated hereby may be abandoned at any time prior to the
Closing Date by Watson if (a) there has been a breach by Seller or Parent of any
representation or warranty contained in this Agreement which would have a
Company Material Adverse Effect; or (b) there has been a material breach of any
of the covenants or agreements set forth in this Agreement on the part of Seller
or Parent which would have a Company Material Adverse Effect, and which breach
is not

                                       53

<PAGE>


curable or, if curable, is not cured within 30 days after written notice of such
breach is given by Watson to Seller.

      8.5 REMEDIES. No party shall be limited to the termination right granted
in Sections 8.3 and 8.4 by reason of the nonfulfillment of any condition to such
party's closing obligations but may, in the alternative, elect to do one of the
following: proceed to close despite the nonfulfillment of any closing condition,
it being understood that consummation of the transaction contemplated herein
shall not be deemed a waiver of a party's wilful breach of any representation,
warranty or covenant or of any party's rights and remedies with respect thereto;
decline to close, terminate this Agreement as provided in Sections 8.3 and 8.4,
and thereafter seek damages to the extent permitted in Section 8.6; or seek
specific performance of the obligations of the other party. Each party hereby
agrees that in the event of any breach by such party of this Agreement, the
remedies available to the other party at law would be inadequate and that such
party's obligations under this Agreement may be specifically enforced.

      8.6 RIGHT TO DAMAGES. If this Agreement is terminated pursuant to Sections
8.3 or 8.4, neither party hereto shall have any claim against the other except
if the circumstances giving rise to such termination were caused by either (a)
the other party's material breach of Article IV; or (b) a party's
representations and warranties contained in Articles II or III are incorrect
when made such that the incorrect representation and warranty would have a
Material Adverse Effect with respect to such party, in which event termination
shall not be deemed or construed as limiting or denying any legal or equitable
right or remedy of said party, and said party shall be entitled to recover,
without limitation, its costs and expenses which are incurred in pursuing its
rights and remedies (including reasonable attorneys' fees).

      8.7 EXTENSION; WAIVER. At any time prior to the Closing Date, any party
hereto may, to the extent legally allowed, (a) extend the time for the
performance of any of the obligations or other acts of the other parties hereto;
(b) waive any inaccuracies in the representations and warranties made to such
party contained herein or in any document delivered pursuant hereto; and (c)
waive compliance with any of the agreements or conditions for the benefit of
such party contained herein. Any agreement on the part of a party hereto to any
such extension or waiver shall be valid only if set forth in an instrument in
writing signed on behalf of such party.

for Rugby to determine whether to accept the Terms. Rugby shall keep the Terms
confidential and shall have ten (10) business days to accept such Terms, which

herein. In the event Rugby does not accept the Terms within such time period,
HMRI may offer such Terms to any other party and may negotiate with another
party ready, willing and able to enter into an agreement; PROVIDED, HOWEVER,

this Agreement only upon the written agreement of HMRI and Rugby; PROVIDED,
HOWEVER, that to the extent that HMRI does not currently have the FDA approvals
necessary to manufacture, market, distribute and sell any of the Products in
package sizes of 500s and 1,000s, upon the request of Rugby, HMRI agrees to
promptly take all actions reasonably necessary (provided that Rugby is
responsible for all costs and expenses related thereto) to obtain all required

distribute each of the Products in such package sizes as requested by Rugby and,
upon HMRI's receipt of the required FDA approvals necessary to manufacture,
market, distribute and sell such Products in such requested package sizes, such
Products in such package sizes shall be deemed to be a "Product" pursuant to the
terms of this Agreement. HMRI may abandon a Product at any time upon prior
written notification to Rugby due to statutory, regulatory or similar
legislative concerns. In the event the statutory, regulatory or similar
legislative concerns are alleviated with respect to a Product and HMRI chooses
to again manufacture such Product, such Product will be included again in this

PROVIDED, HOWEVER, unless otherwise agreed to by the parties, Product may not be
abandoned until January 1, 2000; PROVIDED, FURTHER, that * in finished dosage
form may be abandoned only upon the written agreement of both parties. On or
after January 1, *, Product may be abandoned (i) by Rugby or HMRI upon two (2)
years prior written notice upon a determination of senior management of Rugby or
HMRI, as the case may be, to discontinue sales or the manufacturing of such
Product, as the case may be, or (ii) by Rugby upon one (1) year prior written
notice (which notice may be delivered at any time after January 1, *) upon
approval or acquisition of an abbreviated new drug application for such Product
by Rugby or its Affiliates. If a Product is subsequently abandoned pursuant to
the terms of this Agreement, it will no longer be considered a Product or be
subject to this Agreement; PROVIDED, HOWEVER, in the event that HMRI abandons a
Product pursuant to Section 3.3(a)(i) and determines to manufacture such Product
again, HMRI will provide Rugby the opportunity to distribute and sell such
Product, and if Rugby consents in writing to such inclusion, such Product will
be included again in this Agreement and again become subject to this Agreement.

manufacturing capacity, in the event HMRI abandons a Product (except abandonment
due to statutory, regulatory or similar legislative concerns) or Rugby
terminates the Agreement pursuant to the provisions of Section 4.2(a)(i) or (ii)
herein, then (i) upon six (6) months' prior written notice in the case of
abandonment of a Product, or (ii) on or prior to the termination of this
Agreement by Rugby pursuant to the provisions of Section 4.2(a)(i) or (ii)
herein, Rugby may purchase up to * supply of such abandoned Product (or Products
in the case of termination of the Agreement), which supply is based upon the
amount of Product purchased by Rugby or its subsidiaries over the previous *
months. Any such purchase shall not increase the obligations of HMRI under
Sections 3.10(b) and (c) of this Agreement. The timing for delivery of such
Product shall be reasonably determined by HMRI and shall be based upon the
availability of active ingredient and available manufacturing capacity.

               (b) SALE OF NDA. In the event HMRI determines to sell an NDA to a
third party, HMRI shall notify Rugby in writing of such sale (the "NDA Sale
Notification"), which notification shall specify the NDA to be sold and the
package sizes (SKU) and finished dosage forms of Product manufactured pursuant
to such NDA. As a condition to the sale of the NDA to such third party, HMRI
shall retain such rights sufficient to enable it to, or shall cause such third
party to, license such Product to Rugby on the terms and conditions set forth in
this Agreement. In addition, to the extent that HMRI transfers the manufacturing
responsibility of Product manufactured pursuant to such NDA, as a condition of
such sale, HMRI shall cause such third party to supply such Product, in package
size (SKU) and finished dosage form manufactured pursuant to such NDA, to Rugby
on the terms and conditions set forth in this Agreement; PROVIDED, HOWEVER,
prior to December 31, *, HMRI will guarantee the continued supply to Rugby of
Product(s) manufactured pursuant to such NDA through December 31, * in
accordance with the terms of this Agreement; PROVIDED, FURTHER, on or subsequent
to January 1, *, Rugby may in its discretion remove such Product(s) from this
Agreement by providing written notice to HMRI within thirty (30) days after the
receipt of an NDA Sale Notification, and thereafter such Product(s) shall no
longer be considered a Product or be subject to this Agreement. In any event,
upon the sale of an NDA by HMRI to a third party in which HMRI transfers the
manufacturing responsibility of Product manufactured pursuant to such NDA, the
package sizes (SKU) and finished dosage forms of Product manufactured pursuant
to such NDA shall no longer be considered a Product or be subject to this
Agreement.

               (c) TRANSFER OF TECHNOLOGY. In the event (i) HMRI determines to
abandon a Product pursuant to Section 3.3(a) herein, (ii) HMRI chooses not to
manufacture a Product previously abandoned due to statutory, regulatory or
similar legislative concerns after the statutory, regulatory or similar
legislative concerns are alleviated pursuant to Section 3.3(a), (iii) HMRI
elects not to renew the Agreement in accordance with Section 4.1 herein, or (iv)
Rugby terminates this Agreement pursuant to the provisions of Section 4.2
herein, HMRI agrees to transfer the manufacturing rights (including the HMRI
Know-How relating thereto) to such Product(s) to Rugby as soon as reasonably
practicable after the date of such event; PROVIDED, HOWEVER, HMRI shall have no
obligation to transfer such manufacturing rights to the Proprietary Products. In
the event the manufacturing rights to a Product are transferred to Rugby, until
such time as a second manufacturing site is qualified in connection with such
Product, HMRI will provide assistance reasonably requested by Rugby for the
transition of such manufacturing rights and related HMRI Know-How, including
taking all reasonable steps to allow Rugby to qualify a second manufacturing
site for such Product at a site designated by Rugby pursuant to the NDA and
consent by HMRI to the manufacture by Rugby or its Affiliate of such Product at
such site, and Rugby will be responsible for all of HMRI's reasonable
out-of-pocket costs in connection with the transfer of such manufacturing rights
and related

binding commitment of Rugby to purchase such quantities evidenced by purchase
orders to HMRI pursuant to Section 3.6 herein. In the event it is reasonably
necessary for HMRI to purchase active ingredient for Product beyond the binding
commitment of Rugby, HMRI may request written authorization from Rugby regarding
such purchase. In the event Rugby authorizes such purchase or authorizes a
portion of such purchase, Rugby will be responsible for the costs of the active
ingredient authorized to be purchased which is not used by HMRI in the
manufacture of Product or other products. In the event Rugby does not authorize
such purchase, HMRI shall not be required (but will use commercially reasonable

claim relating to Product that fails to meet the Specifications (other than for
reasons of storage, handling, or shipping by Rugby, its Affiliates, customers
and carriers) within the earlier of (i) ten (10) business days after discovery

               (d) SOLE REMEDY. The provisions of Sections 3.8(a) in the case of
shortage in quantity of any shipment of Product, and except as otherwise
provided in Section 9.2(c) herein, Sections 3.8(b) and (c), in the case of
Product that fails to meet the Specifications, shall be the sole remedy
available to Rugby with respect to any Shortage in quantity of any shipment of
Product, or Product that fails to meet the Specifications, as the case may be.

               III.9 CAPACITY ALLOCATION. In the event HMRI, upon receiving a
forecast pursuant to Section 3.5 or a firm order pursuant to Section 3.6, is or
anticipates that it will be unable to meet such forecast or firm order, either

this Agreement or an ANDA Product under the Contract Manufacturing Agreement, if
Rugby makes a firm order for Product in accordance with Section 3.6 of this
Agreement or an ANDA Product in accordance with Section 2.7 of the Contract
Manufacturing Agreement (for purposes of this Section 3.10(a), such firm order
may be made without regard to the *% forecast limitation or the limitation of
Rugby to place orders only to the extent reasonably sufficient to support its
inventory safety stock) and HMRI is unable to supply any Product or ANDA Product
to Rugby for any reason whatsoever (including a Force Majeure), or if a Product
is abandoned by HMRI due to statutory, regulatory or legislative concerns, HMRI
shall pay Rugby the following amount for each day of such failure: *. During any
period that HMRI is making the payments to Rugby pursuant to this Section 3.10,
Rugby shall pay HMRI the prices set forth in * to this Agreement for the

Manufacturing Agreement after the effective date of the rectification of the
inability to supply.

               (b) At any time prior to the * anniversary of this Agreement, if
Rugby makes a firm order for Product in accordance with Section 3.6 and HMRI is
unable to deliver such Product to Rugby due to a Force Majeure (as defined in
Section 11.3 herein), or if a Product is abandoned by HMRI due to statutory,
regulatory, or legislative concerns due to a Force Majeure, for a period of up
to * from the date of such failure to supply, HMRI will reimburse Rugby for an
amount equal to Rugby's *. If such inability to meet a firm order is partial,
HMRI shall deliver against firm orders such quantities of such Product as are
available. Rugby acknowledges that it shall use its commercially reasonable good
faith efforts to purchase replacement Product at the lowest prices available.
The provisions of Sections 3.10(a) and (b) shall be Rugby's sole remedy for
HMRI's inability to deliver a Product to Rugby due to a Force Majeure in
accordance with this Section 3.10(b).

               (c) During the Initial Term, if Rugby makes a firm order for
Product in accordance with Section 3.6 and HMRI is unable to deliver such
Product to Rugby in accordance with the terms of this Agreement due to any
reason other than a Force Majeure, or if a Product is abandoned by HMRI due to
statutory, regulatory, or legislative concerns due to any reason other than a
Force Majeure, for a period of up to * from the date of such failure to supply,
HMRI will reimburse Rugby for an amount equal to Rugby's *. If such inability to
meet a firm order is partial, HMRI shall deliver against firm orders such
quantities of such Product as are available. Rugby acknowledges that it shall
use its commercially reasonable good faith efforts to purchase replacement
Product at the lowest prices available. The provisions of Sections 3.10(a) and
(c) shall be Rugby's sole remedy for HMRI's inability to deliver a Product to
Rugby in accordance with this Section 3.10(c), except with respect to a willful
breach by HMRI that results in a material adverse effect to Rugby of the value
of this Agreement taken as a whole.

               (d) All amounts owed to Rugby by HMRI pursuant to this Section
3.10 shall bear interest in the same manner as amounts owed by Rugby to HMRI

pursuant to this Section 3.10 for which a credit acknowledgment has been issued
by HMRI against purchases of Product.

               III.11 PRODUCT PRICE. The pricing for the Products is determined
in accordance with HMRI's costs practices (on a capacity basis), as set forth in
the HMRI Product Costing Manual, according to generally accepted accounting
principles. The initial manufacturing costs for the Products, by package size
(SKU) and finished dosage form FOB at HMRI's manufacturing site is set forth in
* and shall be adjusted January 1 of each year during the Term at the rate of
3.5% annually for inflation (except active ingredient, which at all times shall
be at *. In the event either party is able to procure active ingredient at a
lesser price, the parties shall work together (to the extent permitted pursuant
to contractual obligations of the parties) to procure such lower priced active
ingredient. Except as otherwise provided in Section 3.10, the manufacturing
costs for the Products from the date hereof through the * anniversary of this
Agreement shall be as follows: * . As of the * anniversary of this Agreement and

have the * as set forth in Section 3.12). If there is any dispute regarding the
provisions of this Section 3.11, such dispute shall be resolved in accordance
with the provisions of Article 10 herein.

               III.12 PROFIT SPLIT RELATED TO * . Beginning January 1, *and
continuing in perpetuity, Rugby shall make payments to HMRI equal to *% of the
Net Profit of *, based upon the quarterly periods ended March 31, June 30,

this Agreement, the profit split for * shall be calculated as if purchased at
the cost set forth in * Exhibit A to this Agreement. Rugby shall make such
quarterly payments to HMRI in accordance with the provisions of Section 3.14 on
or before forty-five (45) days after the end of each such calendar quarter.
Payment to HMRI shall be accompanied by reasonable detail and documentation
regarding the Net Profit of * for such quarter. Profit split payments made to
HMRI shall reflect the net profit (as calculated in the same manner as the
calculation of Net Profit) received on the bundled sale of *, multiplied by the
following fraction, the numerator of which is equal to the number of units of *
multiplied by the standard invoice unit price thereof, and the denominator of
which is equal to the sum of the number of units of each product (including *)
or service included in such bundled sale multiplied by the respective standard
invoice unit price thereof.

               III.13 ACCESS TO RECORDS.

               (a) Each party shall maintain complete and accurate books and
records of account relating to the manufacturing costs of Product, and sale of
*, as the case may be. Each party shall have the right during the term of this
Agreement and for one year thereafter (and, in the case of HMRI, at any time
while profit split payments with respect to * are being made, and for one year
after the termination of such profit split payments) to examine the relevant
books and records of the other party relating to the manufacturing costs of
Products, and sale of *, as the case may be, during normal business hours and
upon reasonable advance written notice to verify the correctness of the
calculations of the cost of goods of the Products, or the profit split of *, as
the case may be. Each party shall cooperate with the other with respect to all
reasonable requests made with respect to such inspection.

               (b) Each party shall have three (3) years after receipt of
payments pursuant to this Agreement or receipt of information relating to the
manufacturing costs of Products, as the case may be (the "Dispute Period") to
dispute the amount of any such payment pursuant to this Agreement or the
manufacturing costs of Products, as the case may be (a "Dispute"). If a party
does not give written notice of a Dispute within the Dispute Period to the other
(a "Dispute Notice"), the amount of such payment or the manufacturing costs, as
the case may be, shall be deemed to have been accepted and agreed to by the
other and shall be final and binding upon the parties hereto. If a party has a
Dispute, it shall promptly send the other party a Dispute Notice within the
Dispute Period, setting forth in reasonable detail the elements and amounts with
which it disagrees. Within thirty (30) days after delivery of such Dispute
Notice, the parties hereto shall attempt to resolve such Dispute and agree in
writing upon the final amount of the disputed item. No dispute shall be made
with respect to any payments made pursuant to Section 3.12 or the manufacturing
costs of the Products, as the case may be, that have previously been disputed by
a party in a review of the records of a party relating the calculation of
payments pursuant to Section 3.12 or the manufacturing costs of the Products, as
the case may be.

               (c) If the parties are unable to resolve any Dispute within the
thirty (30) day period after receipt of a Dispute Notice, the New York office of
the certified public accounting firm of Arthur Andersen LLP (the "Arbitrating
Accountant") shall be engaged as arbitrator hereunder to settle such Dispute as
soon as practicable. In the event Arthur Andersen LLP is unwilling or unable to
serve as the Arbitrating


                                      -12-

<PAGE>


Accountant, the parties hereto shall select by mutual agreement another
nationally recognized certified public accounting firm, who is not rendering
(and during the preceding two-year period has not rendered) services to either
HMRI, Rugby, or any of their respective Affiliates, to serve as the Arbitrating
Accountant. In connection with the resolution of any Dispute, the Arbitrating
Accountant shall have access to all documents, records, work papers, facilities
and personnel necessary to perform its function as arbitrator. The arbitration
before the Arbitrating Accountant shall be conducted in accordance with the
commercial arbitration rules of the American Arbitration Association. The
Arbitrating Accountant's award with respect to any Dispute shall be final and
binding upon the parties hereto, and judgment may be entered on the award. Each
party shall pay one-half of the fees and expenses of the Arbitrating Accountant
with respect to any Dispute.

               III.14 PAYMENT. All payments required by this Agreement shall be
made in United States Dollars. All invoices are strictly net and payment must be
received within forty-five (45) days from the date of invoice. The date of each
invoice shall be the date of shipment of products. Payment shall be made without
deduction, deferment, set-off, lien or counterclaim of any nature, other than
for rejected or returned goods, or credits issued by HMRI pursuant to Section
3.10 herein, in each case for which a credit acknowledgment has been issued by
HMRI. Time for payment shall be of the essence. Unless Rugby notifies HMRI in
writing of a good faith dispute, with respect to payments not received within
such forty-five (45) days, or within forty-five (45) days after the end of each
calendar quarter with respect to payments pursuant to Section 3.12 herein,
interest shall accrue on any amount overdue, at the rate of prime plus 2%, such
interest to begin accruing on a daily basis from the date of invoice, and shall
accrue both before and after judgment; PROVIDED, HOWEVER, in the case of a good
faith dispute regarding payment resolved to be due and not paid within three (3)
business days after such resolution, interest shall accrue on any amount
overdue, at the rate of prime plus 2%, such interest to begin accruing on a
daily basis from the date such payment becomes overdue, and shall accrue both
before and after judgment; PROVIDED, FURTHER, in the case of a good faith
dispute regarding payment, Rugby may in its discretion determine to pay such
amounts disputed to be overdue and in the event amounts are finally determined
not to be due by Rugby, HMRI shall repay such excess amounts determined not be
due to Rugby, and interest shall accrue on any such amount, at the rate of prime
plus 2%, such interest to begin accruing on a daily basis from the date such
disputed payment was received by HMRI.

               With respect to defaults of payment not cured within ten (10)
business days after receipt of written notice from HMRI to Rugby, HMRI shall, in
its sole discretion, and without prejudice to any other of its accrued rights,
be entitled to suspend the provision of the Products or to treat the Agreement
as repudiated by notice in writing to Rugby exercised at any time thereafter;
PROVIDED, HOWEVER, a good faith bona fide dispute by Rugby regarding a payment
pursuant to this Agreement shall not be considered a default of payment so long
as Rugby notifies HMRI in writing of such dispute within the later of five (5)
business days from the date of invoice or the date of payment. Rugby
acknowledges it will notify HMRI promptly upon a determination that a dispute
exists regarding a payment.

               III.15 ADVERTISING/MARKETING/SALES COSTS AND PRODUCT PRICING.
Rugby shall be responsible for all advertising, marketing and sales costs
associated with Product distribution. Rugby will have complete authority for all
pricing decisions for the Product. Rugby shall not alter the Products and shall
not recommend or knowingly sell the Products for any uses except as described in
the FDA approved Product labeling.

               III.16 TAXES. Rugby shall reimburse HMRI for all tariffs, duties

included in the product pricing set forth in Section 3.11 herein.
Notwithstanding the foregoing, Rugby shall have no reimbursement obligations
pursuant to this Section 3.16 to the extent that (i) such Taxes are based on
HMRI's net income or (ii) such Taxes are recoverable or offset by HMRI, in whole
or in part, as a credit, rebate, deduction or otherwise.

                                   ARTICLE IV
                              TERM AND TERMINATION

               IV.1 TERM. The Initial Term of this Agreement will commence upon
the execution of this Agreement and will continue until December 31, *, unless
terminated earlier in accordance with the provisions of Section 4.2 herein.
Thereafter, this Agreement will automatically continue until either party
provides not less than * prior written notification to the other that this
Agreement will terminate, which notification shall specify the date upon which

Agreement forthwith by notice in writing to the other party upon the occurrence
of any of the following events:

                      (i) if the other party commits a material breach of this
               Agreement, other than a payment default, which in the case of a
               breach capable of remedy shall not have been remedied within
               thirty (30) days of the receipt by the other party of a notice
               identifying the breach and requiring its remedy or such longer
               time as the party in breach may demonstrate to the other party is
               necessary to remedy the breach using its reasonable efforts to do
               so; or

                      (ii) if the other party ceases for any reason to carry on
               business or convenes a meeting of its creditors or has a receiver
               or manager appointed in respect of all or substantially all of
               its assets or is the subject of an application for an

               arrangement or enters into liquidation (whether compulsorily or
               voluntarily) or undergoes any analogous act or proceedings under
               foreign law; or

                      (iii) the enactment of any law, order or regulation by a
                governmental unit that would render it impossible for the other
                party to perform its obligations hereunder. In the event Rugby
                terminates this Agreement pursuant to this Section 4.2, HMRI
                will take all reasonable actions to allow Rugby to manufacture
                the Products in accordance with Section 3.3(c ) herein, except
                with respect to the Proprietary Products.

               IV.3 CONSEQUENCES OF TERMINATION AND SURVIVAL. Termination of

information supplied to, or supplied by, the FDA or other governmental
regulatory agency, including the Form 483 observations and responses, to the
extent such information relates to the Products (or the ability of HMRI to
supply such Product), within five (5) business days of HMRI's receipt of such
information or delivery of such information, as the case may be.

               V.3 CHANGES. HMRI shall provide written notification to Rugby a
reasonable time in advance prior to changing the critical specified raw

and adverse drug event reports received by it, together with all available
evidence and other information relating thereto. Except as otherwise required by
law or governmental regulation, HMRI will be responsible for investigating and
responding to all such inquiries, complaints and adverse events regarding
Product. It shall be the responsibility of HMRI to comply with all federal,
state and local governmental reporting requirements regarding adverse drug
events and Product quality matters, except where such events or matters are
caused by acts or omissions of Rugby, in which case HMRI may, consistent with
applicable law and regulation, request Rugby's assistance in such compliance.
HMRI will forward a copy of all FDA submissions concerning Product adverse drug
events or any Product safety-related topic to Rugby within five (5) business
days of submission. In the event of a dispute in respect of the therapeutic
action or quality of a Product: (i) if the dispute involves only Rugby and a
subsequent purchaser then Rugby and HMRI shall consult prior to any compromise
or settlement of such dispute; and (ii) if the dispute involves Rugby, HMRI and
a subsequent purchaser then both parties must consent prior to any compromise or
settlement of such dispute.

               V.7 RESPONSE TO COMPLAINTS AND/OR ADVERSE DRUG REACTIONS (OR
EVENTS). Pursuant to reported complaint and/or adverse drug reaction (or event),
if the nature of the reported complaint and/or adverse drug reaction (or event)
requires testing, HMRI will, at Rugby's reasonable request and expense, perform
analytical testing of corresponding retention samples and provide the results
thereto to Rugby as soon as reasonably practicable; PROVIDED, HOWEVER, that HMRI
shall be responsible for the reasonable costs of such testing and reporting to
the FDA or any other governmental regulatory agency if it is determined that


                                      -16-


<PAGE>


HMRI is responsible for such reported complaint and/or adverse drug reaction (or
event). Such testing shall be performed using NDA approved testing procedures.

               V.8 ADDITIONAL INFORMATION. Rugby shall provide to HMRI in a
timely manner, but in no event less than sixty (60) days prior to the due date
of HMRI's annual report to the FDA with respect to the Products, all information
(in written form) which HMRI requests regarding the Products in order to comply
with applicable federal and state drug laws. Such information shall include,
without limitation, quantities of each Product sold. Rugby shall be responsible
for assuring that all promotional material produced by it relating to Products
comply with federal, state and local law. Rugby shall provide to HMRI prior to
first use copies of all advertising, promotional material, labeling and other
literature used on, or in connection with, the Products. HMRI shall provide to
Rugby a copy of such FDA annual report.

               VI.1 PRODUCT RECALLS. In the event (i) any government authority
issues a request, directive or order that Product be recalled, (ii) a court of
competent jurisdiction orders such a recall, or (iii) HMRI shall reasonably
determine that Product should be recalled, the parties shall take all
appropriate corrective actions, and shall cooperate in the investigations
surrounding the recall. In the event that HMRI determines that Product should be
recalled, HMRI shall consult with Rugby prior to taking any corrective actions.
In the event that such recall results from any cause or event other than that
arising from the storage, distribution or handling of the recalled Product by
Rugby or its Affiliates or the negligence of Rugby or its Affiliates, HMRI shall
be responsible for all documented out-of-pocket expenses of such recall
consistent with directions received from the appropriate governmental authority.
In the event that such recall results from any cause or event arising from the
storage, distribution or handling of the recalled Product by Rugby or its
Affiliates or the negligence of Rugby or its Affiliates, Rugby shall be
responsible for all such documented out-of-pocket expenses. For purposes of this
Agreement, the expenses of recall shall include the expenses of notification and
destruction or return of the recalled product and all other costs incurred in
connection with such recall, but shall not include lost profits of either party.

               VI.2 DISPUTES. If there is any dispute concerning which party's
acts or omissions gave rise to such recall of Product, such dispute shall be
referred for decision to an independent expert (acting as an expert and not as
an arbitrator) to be appointed by agreement between Rugby and HMRI or, in the
absence of agreement, by the President for the time being of the Pharmaceutical
Research and Manufacturers of America. The costs of such independent expert
shall be borne equally between Rugby and HMRI. The decision of such independent
expert shall be in writing and, except for manifest error on the face of the
decision, shall be binding on both Rugby and HMRI.

                  NONDISCLOSURE, CONFIDENTIALITY AND TRADEMARKS

               VIII.1 NONDISCLOSURE OBLIGATIONS.

               (a) Except as otherwise specifically provided in this Agreement,
Rugby acknowledges that the HMRI Know-How with which it may be supplied pursuant
to this Agreement or otherwise is supplied in circumstances imparting an
obligation of confidence and agrees to keep such HMRI Know-How secret and
confidential and to respect HMRI's proprietary rights therein and to use the
same for the sole purpose of this Agreement and during the period of this
Agreement or at any time for any reason whatsoever not to disclose or cause or
permit to be disclosed such HMRI Know-How to any third party.

employees of its Affiliates or consultants and contractors shall have access to
HMRI Know-How on a need to know basis and shall be


                                      -18-


<PAGE>

subject to the same obligations of confidence as the principals pursuant to
Section 8.1(a) above and shall enter into secrecy agreements in support of such
obligations. Insofar as this is not reasonably practicable, the principals shall
take all reasonable steps to ensure that any such employees, consultants and
contractors are made aware of such obligations.

               (c) Both parties undertake and agree not to disclose or permit to
be disclosed at any time for any reason whatsoever to any third party or
otherwise make use of or permit to be made use of any trade secrets or
confidential information relating to the technology, business affairs or

licensees, licensors or other customers of the other which comes into their
possession pursuant to this Agreement.

               (d) The obligations of confidence referred to in this Section 8.1
shall not extend to any information which:

                       (i) is or becomes part of the public domain other than by
               unauthorized acts of the party obligated not to disclose such
               Information or its Affiliates or sublicensees, as applicable;

                      (ii) can be shown by written documents to have been
               disclosed to the receiving party or its Affiliates or
               sublicensees by a third party, provided such Information was not
               obtained by such third party directly or indirectly from the
               other party under this Agreement pursuant to a confidentiality
               agreement;

                      (iii) prior to disclosure under this Agreement, was
               already in the possession of the receiving party or its
               Affiliates or sublicensees, provided such Information was not
               obtained directly or indirectly from the other party under this
               Agreement pursuant to a confidentiality agreement;

                      (iv) can be shown by written documents to have been
               independently developed by the receiving party or its Affiliates
               without breach of any of the provisions of this Agreement;

                      (v) is disclosed by the receiving party pursuant to oral
               questions, interrogatories, requests for information or
               documents, subpoena, or a civil investigative demand of a court
               or governmental agency; provided that the receiving party
               notifies the other party immediately upon receipt thereof (and
               provided that the disclosing party furnishes only that portion of
               the information which it is advised by counsel is legally
               required and impose such obligations of secrecy as are possible
               in that regard); or

                      (vi) is required to be disclosed by a party under any
               statutory, regulatory or similar legislative requirement or any
               rule of any stock exchange to which it or any Affiliate is
               subject, subject to the obligation of secrecy as are possible in
               that regard.

disclose any terms or conditions of this Agreement to any third party without
the prior consent of the other party, except as required by applicable law.
Notwithstanding the foregoing, prior to execution of this Agreement, Rugby and
HMRI shall agree upon the substance of information that can be used as a routine
reference in the usual


                                      -19-

<PAGE>


course of business to describe the terms of this Agreement from time to time,

determines that excessive use of such statement is made by the other party, then
the party determined to be using such statement excessively shall, upon notice
by the other party, cease making such statement.

               VIII.3 INJUNCTIVE RELIEF. The parties hereto understand and agree
that remedies at law may be inadequate to protect against any breach of any of
the provisions of this Article 8 by either party or their employees, agents,
officers or directors or any other person acting in concert with it or on its
behalf. Accordingly, each party shall be entitled to the granting of injunctive
relief by a court of competent jurisdiction against any action that constitutes
any such breach of this Article 8.

               VIII.4 TRADEMARKS.

                      (a) HMRI TRADEMARKS. Rugby acknowledges that HMRI and its
Affiliates are the exclusive owner of (i) the trademarks, service marks, slogan,

Affiliates (collectively, the "HMRI Intellectual Property Rights"). In addition,
Rugby acknowledges that HMRI is the exclusive owner of the NDAs and any
supplements thereto. Rugby acknowledges that it shall have no rights hereunder
to any such HMRI Intellectual Property Rights and agrees that it shall not
contest or dispute the validity of or title to any of such HMRI Intellectual
Property Rights. Rugby agrees it shall not take or cooperate in litigation or
threatened litigation which might or is intended to impair or attack the HMRI
Intellectual Property Rights. Rugby shall market the Products under its own
trade names and trademarks, which shall not be confusingly similar to the HMRI
Intellectual Property Rights.

                      (b) RUGBY TRADEMARKS. HMRI acknowledges that Rugby and its
Affiliates are the exclusive owner of (i) the trademarks, service marks, slogan,
trade names, trade dress and the like (including the associated goodwill of
each) held by Rugby or its Affiliates and (ii) all copyrights held by Rugby or
its Affiliates (collectively, the "Rugby Intellectual Property Rights"). HMRI
acknowledges that it shall have no rights hereunder to any such Rugby
Intellectual Property Rights and agrees that it shall not contest or dispute the
validity of or title to any of such Rugby Intellectual Property Rights. HMRI
agrees it shall not take or cooperate in litigation or threatened litigation
which might or is intended to impair or attack the Rugby Intellectual Property
Rights.

                                   ARTICLE IX
                    LIMITATION OF LIABILITY, INDEMNIFICATION AND INSURANCE

               IX.1 INDEMNIFICATION BY RUGBY. Except as otherwise specifically
provided herein, Rugby shall indemnify and maintain HMRI against all claims,
actions, costs, expenses (including court costs and legal fees on a full
indemnity basis) or other liabilities ("Liabilities") whatsoever in respect of:

               (a) any negligence or willful misconduct of Rugby in relation to
the use, marketing, storage, distribution, handling or sale of Product;

               (b) any labeling of any Product to the extent that such labeling
has been supplied by or at the direction of Rugby and applied in accordance with
instructions from Rugby; and


                                      -20-

<PAGE>


               (c) any representation or warranty made by Rugby to its customers
or users with respect to Product, other than representations or warranties
contained in Article VII herein.

               IX.2 INDEMNIFICATION BY HMRI. Except as otherwise specifically
provided herein, HMRI shall indemnify and maintain Rugby against all Liabilities
whatsoever in respect of:


               (a) any defective design product liability claim with respect to
a Product;

               (b) any labeling of any Product to the extent such labeling is
supplied by or at the direction of HMRI;

               (c) HMRI's failure to comply with the Specifications; and

               (d) any negligence or willful misconduct by HMRI in the
manufacture, packaging, storage, handling or shipping of Product.

               IX.3 INDEMNIFICATION PROCEDURES. A party (the "Indemnitee") that
intends to claim indemnification under this Article 9 shall:

               (a) notify the other party (the "Indemnitor") of any Liability
with respect to which the Indemnitee intends to claim indemnification as soon as
practicable after the Indemnitee becomes aware of any such Liability;

               (b) permit the Indemnitor to assume the defense thereof with
counsel mutually satisfactory to the parties; and

               (c) cooperate with the Indemnitor, at the Indemnitor's expense,
in the defense thereof.

               With respect to any matter for which the Indemnitor has an
obligation to indemnify the Indemnitee under this Agreement, the Indemnitee
shall have the right to participate and be represented (at the Indemnitor's
expense) by legal counsel of the Indemnitee's choice in all proceedings and
negotiations, if representation by counsel retained by Indemnitor would be
inappropriate due to actual or potential differing interests between the
Indemnitee and any other party represented by such counsel in such proceedings.
The indemnity agreement in this Article 9 shall not apply to amounts paid in
settlement of any Liability if such settlement is effected without the consent
of the Indemnitor, which consent shall not be unreasonably withheld. Failure of
the Indemnitee to deliver notice to the Indemnitor within a reasonable time
after becoming aware of a Liability shall relieve the Indemnitor of any
liability to the Indemnitee pursuant to this Article 9 in the event such delay
is prejudicial to the Indemnitor's ability to defend such action.

               IX.4 DISTRIBUTION INSURANCE. Rugby shall obtain and maintain in
effect for the term of this Agreement, liability insurance or indemnity policies
with an insurer reasonably acceptable to HMRI, in an amount not less than *with
an indemnity to principals clause with respect to the distribution of each
Product, which policies shall name HMRI as an additional insured and shall be
blanket policies. Such policies shall insure against liability on the part of
Rugby and any of its Affiliates, as their interests may appear, due to injury,
disability or death of any person or persons, or injury to property, arising
from the


                                      -21-


<PAGE>
                           "*SEE PAGE ONE OF EXHIBIT"

January 1 each year during the Term, Rugby shall provide to HMRI a certificate
of insurance (i) summarizing the insurance coverage, (ii) identifying any
exclusions and (iii) indicating that the terms of Rugby's insurance policies are
in accordance with this Section 9.4. Rugby shall promptly notify HMRI of any
alterations to the terms of this policy or in the amounts for which insurance is
provided.

               IX.5 MANUFACTURER'S INSURANCE. HMRI shall obtain and maintain in
effect for the term of this Agreement, liability insurance or indemnity policies
with an insurer reasonably satisfactory to Rugby, in an amount not being less
than *with an indemnity to principals clause with respect to the manufacture,
storage or handling of Product, which policies shall name Rugby as an additional
insured and shall be blanket policies. Such policies shall insure against
liability on the part of HMRI and any of its Affiliates, as their interests may
appear, due to injury, disability or death of any person or persons, or injury
to property arising from the negligence of HMRI in the manufacture of Product.
Upon the execution of this Agreement and thereafter on January 1 each year
during the Term, HMRI shall provide to Rugby a certificate of insurance (i)
summarizing the insurance coverage, (ii) identifying any exclusions and (iii)
indicating that the terms of HMRI's insurance policies are in accordance with
this Section 9.5. HMRI shall promptly notify Rugby of any alterations to the
terms of the policy or in the amounts for which insurance is provided.

               IX.6 PRODUCT LIABILITY CLAIMS. As soon as it becomes aware, each
party will give the other prompt written notice of any defect or alleged defect
in a Product, any injury alleged to have occurred as a result of the use or
application of a Product, and any circumstances that may give rise to litigation
or recall of a Product or regulatory action that may affect the sale or
manufacture of a Product, specifying, to the extent the party has such
information, the time, place and circumstances thereof and the names and
addresses of the persons involved. Each party will also furnish promptly to the
other copies of all papers received in respect of any claim, action or suit
arising out of such alleged defect, injury or regulatory action.

it via telephone, telefax or other written or oral contact, the Mediation
Committee shall meet in person, not later than twenty (20) days following
submission of the matter to it, at a mutually convenient place to attempt in
good faith to resolve the dispute. If the Mediation Committee is unable to

relating to product recalls as set forth in Article 6 herein, Disputes as set
forth in Section 3.13, and the matters set forth in Section 8.3 shall not be
submitted to arbitration pursuant to Section 10.3 hereof but instead shall be
resolved in accordance with Section 6.2, 3.13 and 8.3 herein, respectively.

the date of the Response, each party shall submit to the other parties a list of
all witnesses intended to be called at the hearing. Each party shall use its
commercially reasonable good faith efforts to make available for deposition
within thirty (30) days after the delivery of the list of witnesses at each
party's respective location of its operations, all of its agents, employees, and
Affiliates who have direct knowledge of the dispute at such times and places
that shall not unreasonably disrupt the business of the other parties. The chair
of the Arbitration Panel shall determine all discovery disputes and may enforce
a decision by imposing appropriate sanctions on the non-complying party.

                   X.6.5 RECORD. A stenographic record of all proceedings shall
be made and oaths administered by a duly licensed and qualified court reporter.
The court reporter shall prepare five (5) copies of the stenographic record of

party or representative who, after due notice, fails to be present or fails to
obtain a postponement. An award shall not be made solely on the default of a

either party to require the strict performance of any term, covenant or
condition of this Agreement or to exercise any right or remedy available on a
breach thereof shall constitute a waiver of any such breach or of any such term
or condition. The consent to, or the waiver of, any breach, or the failure to
require on any single occasion the performance or timely performance of any
term, covenant, or condition of this Agreement shall not be construed as
authorizing any subsequent or additional breach and shall not prevent a
subsequent enforcement of such term, covenant, or condition.

Agreement or the application thereof to any party or circumstance shall be
finally determined by a court of proper jurisdiction to be invalid or

enforceable, the intent and purpose of such invalid and unenforceable provision
and (ii) the remainder of this Agreement and the application of such provision

unenforceable shall not be affected thereby.

that (i) each party and its representatives has reviewed and negotiated the
terms and provisions of this Agreement and have contributed to its revision,

this Agreement.

in two counterparts, each of which shall be deemed an original, but both of

In the event that a Product is removed from this Agreement pursuant to the
provisions of this Section 2.1, then upon fulfillment of its binding obligation
to purchase such Product in accordance with Section 2.6(b) herein, such Product
shall be removed from this Agreement and shall no longer be considered a Product

among HMRI, Marisub, Inc. and Watson Pharmaceuticals, Inc. (the "Stock Purchase

and capsules (which volume shall be based upon finished package size (SKU)) of
Product subject to this Agreement is reduced to a level which is equal to or
less than *% of the annual aggregate volume of tablets and capsules of Product
ordered by Rugby from HMRI during the twelve (12) month period prior to the date
hereof, HMRI may in its sole discretion terminate this Agreement by providing
written notification of such intent to Rugby.

generic versions of each Product in finished dosage forms listed on Exhibit B
attached hereto will be added to the terms of this Agreement upon written
notification by Rugby to HMRI that ANDA approval has been attained; and (ii) to
the extent that HMRI does not currently have the FDA approvals necessary to
manufacture, market, distribute and sell any of the Products in package sizes of
500s and 1,000s, upon the request of Rugby, HMRI agrees to promptly take all
actions reasonably necessary (provided that all costs and expenses related

Rugby's sole cost and expense thereafter) to obtain all required consents and
approvals from the FDA in order to manufacture, market and distribute each of
the Products in such package sizes as requested by Rugby and, upon HMRI's
receipt of the required FDA approvals necessary to manufacture, market,
distribute and sell such Products in such requested package sizes, such Products

this Agreement. Rugby may abandon Product at any time upon prior written
notification to HMRI due to statutory, regulatory or similar legislative
concerns. In the event the statutory, regulatory or similar legislative concerns
are alleviated with respect to a Product and Rugby chooses to again sell such
Product, Rugby will provide HMRI the opportunity to manufacture such Product and
in the event HMRI consents in writing to manufacture such Product, such Product
will be included again in this Agreement and again become subject to this
Agreement. In addition, Product may be abandoned by Rugby upon * written
notification by Rugby to HMRI (upon a determination of senior management of
Rugby to discontinue sales of such Product), which written notification shall
specify the package size (SKU) and finished dosage form to be abandoned;
provided, however, unless otherwise agreed to by the parties, Product may not be
abandoned until January 1, *; provided, further, that *, in finished dosage form
may be abandoned only upon the written agreement of both parties. If a Product
is subsequently abandoned pursuant to the terms of this Agreement, it will no
longer be considered a Product or be subject to this Agreement; provided,
however, in the event that Rugby determines to sell such Product again, Rugby
will provide HMRI the opportunity to manufacture such Product and in the event
HMRI consents in writing to manufacture such Product, such Product will again be
included and become subject to the terms of this Agreement. Rugby shall be
deemed to have abandoned a Product if its forecasted purchases of such Product
is equal to zero for *.

     Subject to the availability of active ingredients and manufacturing
capacity, in the event Rugby terminates the Agreement pursuant to the provisions
of Section 3.2(a)(i) and (ii) herein, then on or prior to the termination of
this Agreement, Rugby may purchase up to * supply of such Products, which supply
is based upon the amount of Product purchased by Rugby or its Subsidiaries over
the previous *. Any such purchase shall not increase the obligations of HMRI
pursuant to Sections 2.11(a) and (b) of this Agreement. The timing for delivery
of such Product shall be determined by HMRI and shall be based upon the
availability of active ingredient and available manufacturing capacity.

              (b) Site Qualification. During the Term, HMRI agrees to provide
technical consultation reasonably requested by Rugby that HMRI is reasonably
able to provide for the qualification of a second manufacturing site for up to *

               (b) Short-Term Forecasts. Upon execution of this Agreement, and
thereafter at least thirty (30) days prior to the first (1st) day of each
succeeding *, Rugby will furnish HMRI with a rolling forecast of the quantities
of each Product, by package size (SKU) and finished dosage form, that Rugby
intends to order during the * period commencing with that *, stipulating
periodic delivery requirements. The first * of such forecast shall constitute a
binding commitment of Rugby to purchase such quantities evidenced by purchase
orders to HMRI pursuant to Section 2.6 herein. In the event it is reasonably
necessary for HMRI to purchase active ingredient for Product beyond the binding
commitment of Rugby, HMRI may request written authorization from Rugby regarding
such purchase. In the event Rugby authorizes such purchase, or authorizes a
portion of such purchase, Rugby will be responsible for the costs of the active
ingredient authorized to be purchased which is not used by HMRI in the
manufacture of Product or other products. In the event Rugby does not authorize
such purchase, HMRI shall not be required (but shall use commercially reasonable
efforts) to meet Rugby's forecasts or orders with respect to the Products
manufactured with such active ingredient. Rugby will be required to purchase
that percentage of the quantity of each Product specified in the short-term
forecast for successive * as follows:

*% of the most current forecast underlying such order, or may reject any order
which (i) except as otherwise provided in Section 2.15 regarding a good faith
payment dispute by Rugby, is received at a time when Rugby is delinquent in
payment hereunder or (ii) cannot be filled due to circumstances arising under
Section 10.3. Rugby acknowledges it will make good faith forecasts of the
quantities of each Product, by package size and finished dosage form, that Rugby
intends to order and will only place orders for Product to the extent reasonably
sufficient to support its inventory safety stock. Subject to availability of
active ingredient, HMRI will use its reasonable commercial efforts to supply
orders which exceed *% of the most current forecast underlying such order. All
rejections by HMRI shall be in writing and delivered to Rugby within five (5)
business days of HMRI's receipt of the order. HMRI shall deliver against each
such order in accordance with Section 2.7 herein. Rugby shall be obligated to
purchase all such Product, by package size (SKU) and finished dosage form,
ordered and delivered by the delivery date specified in Rugby's purchase order,

confirmation or waybill be deemed to modify or substitute for the terms and
conditions of this Agreement. All such documents shall be subject to, and shall
be deemed to incorporate, the terms and conditions of this Agreement. The
parties acknowledge that the binding commitments of Rugby to purchase Product in
accordance with the rolling forecast of Rugby in effect on the date hereof,

Product  fails to meet the  Specifications  which  HMRI and Rugby are  unable to
resolve,  a sample of such Product shall be submitted by Rugby to an independent
laboratory  reasonably  acceptable  to both  parties  for  testing  and the test
results obtained by such laboratory shall be final and controlling. The fees and
expenses of such laboratory testing shall be borne entirely by the party against
whom such laboratory's findings are made. In the event the test results indicate

thirty (30) day period after receipt of a Dispute Notice, the New York office of
the certified  public  accounting firm of Arthur Andersen LLP (the  "Arbitrating
Accountant") shall be engaged as arbitrator  hereunder to settle such Dispute as
soon as practicable.  In the event Arthur Andersen LLP is unwilling or unable to
serve as the Arbitrating  Accountant,  the parties hereto shall select by mutual
agreement another nationally recognized certified public accounting firm, who is
not  rendering  (and  during the  preceding  two-year  period has not  rendered)

papers,   facilities  and  personnel   necessary  to  perform  its  function  as
arbitrator. The arbitration before the Arbitrating Accountant shall be conducted
in accordance with the commercial  arbitration rules of the American Arbitration
Association.  The  Arbitrating  Accountant's  award with  respect to any Dispute

interest shall accrue on any amount overdue, at the rate of prime plus 2%, such
interest to begin accruing on a daily basis from the date of invoice, and shall
accrue both before and after judgment; provided, however, in the case of a good
faith dispute regarding payment resolved to be due and not paid within three (3)
business days after such resolution, interest shall accrue on any amount
overdue, at the rate of prime plus 2%, such interest to begin accruing on a
daily basis from the date such payment becomes overdue, and shall accrue both

not be due, and interest shall accrue on any such amount, at the rate of prime
plus 2%, such interest to begin accruing on a daily basis from the date such
disputed payment was received by HMRI.

"Taxes") that are paid by HMRI that are directly related to the manufacture and
sale to Rugby of the Products and which are not otherwise included in the
product pricing set forth in Section 2.12. Notwithstanding the foregoing, Rugby
shall have no reimbursement obligations pursuant to this Section 2.17 to the
extent that (i) such Taxes are based on HMRI's net income or (ii) such Taxes are
recoverable or offset by HMRI, in whole or in part, as a credit, rebate,

          IV.1 Certificates of Analysis. HMRI shall perform, or cause to be
performed, sample tests on each lot of Product manufactured pursuant to this
Agreement before delivery to Rugby. Each test report shall set forth the items
tested, Specifications and test results in a certificate of analysis, containing

certificates to Rugby prior to delivery of each lot unless otherwise agreed.

          IV.2 Certificates of Manufacturing Compliance. HMRI shall provide, or
cause to be provided, for each lot of Product manufactured pursuant to this
Agreement, a certificate of manufacturing compliance, containing the types of
information which shall have been approved by mutual agreement of the parties,

Specifications and the GMP. HMRI shall advise Rugby promptly if an authorized
agent of the FDA or other governmental regulatory agency visits any of HMRI's
manufacturing facilities, or the facilities where the Products are being
manufactured, concerning the Products. HMRI shall furnish to Rugby all material
information supplied to, or supplied by, the FDA or other governmental
regulatory agency, including the Form 483 observations and responses, to the
extent that such report relates to Products (or the ability of HMRI to supply
such Product), within five (5) business days of HMRI's receipt of such
information or delivery of such information, as the case may be.

          IV.3 Changes. HMRI shall not change the critical specified raw
materials, packaging materials, their source, analytical test procedures or
critical manufacturing conditions or manufacturing equipment used in the
manufacture of Product without the prior written consent of Rugby, which consent

          IV.4 Access to Facilities.



<PAGE>


                 (a) Rugby Access.  Upon the reasonable prior written request of
Rugby, Rugby shall have the right to inspect those portions of the manufacturing
and testing  facilities of HMRI where Products are being manufactured or tested,
as the case may be, during regular business hours, to ascertain  compliance with
GMPs. If the FDA or other applicable  governmental regulatory agency asserts any
notice to the effect that HMRI has failed to comply  with any law or  regulation
in connection with the manufacture of Products, or if HMRI delivers Product that
does not meet the  Specifications,  then  Rugby  shall have the right to inspect
such  portions  of the  manufacturing  facilities  of HMRI  that  relate  to the
manufacture of Product upon reasonable  notice and during normal business hours.
Notwithstanding  the  provisions  of this  Section  4.4(a),  Rugby shall have no
obligation or be deemed to have an obligation to inspect the  manufacturing  and
testing facilities of HMRI.

               (b) HMRI Access.  Upon the  reasonable  prior written  request of
HMRI,  HMRI shall have the right to inspect those  portions of the warehouse and
distribution   facilities   of  Rugby  where   Products  are  being  stored  and
distributed,  during regular  business  hours,  to observe  Product  storage and
distribution  or  other  related  activities.  If the  FDA or  other  applicable
governmental  regulatory  agency asserts any notice to the effect that Rugby has
failed to comply with any law or regulation  in  connection  with the storage or
distribution  of  Products,  then  HMRI  shall  have the right to  inspect  such
portions of the  warehouse and  distribution  facilities of Rugby that relate to
the storage or distribution of Product upon reasonable  notice and during normal
business  hours.  Notwithstanding  the provisions of this Section  4.4(b),  HMRI
shall have no  obligation  or be deemed to have an  obligation  to  inspect  the
warehouse and distribution facilities of Rugby.

          IV.5 Regulatory Correspondence. Rugby and HMRI shall make available
(or cause to be made available) to each other within three (3) days of receipt
of regulatory correspondence regarding regulatory letters, withdrawal of
Product, and correspondence bearing on the safety and efficacy of the Product.

          IV.6 Product Inquiries and Complaints. Rugby will promptly submit to
HMRI all Product safety and efficacy inquiries, Product quality complaints and
adverse drug event reports received by it, together with all available evidence
and other information relating thereto. Except as otherwise required by law or
governmental regulation, Rugby will be responsible for investigating and
responding to all such inquiries, complaints and adverse events regarding
Product. It shall be the responsibility of Rugby to comply with all federal,
state and local governmental reporting requirements regarding adverse drug
events and Product quality matters, except where such events or matters are
caused by acts or omissions of HMRI, in which case Rugby may, consistent with
applicable law and regulation, request HMRI's assistance in such compliance.
Rugby will forward a copy of all FDA submissions concerning Product adverse drug
events or any Product safety-related topic to HMRI within ten (10) business days
of submission.



<PAGE>


          IV.7 Response to Complaints and/or Adverse Drug Reactions (or Events).
Pursuant to reported complaint and/or adverse drug reaction (or event), if the
nature of the reported complaint and/or adverse drug reaction (or event)
requires testing, HMRI will, at Rugby's reasonable request and expense, perform
analytical testing of corresponding retention samples and provide the results
thereto to Rugby as soon as reasonably practicable; provided, however, HMRI
shall be responsible for the reasonable costs of such testing and reporting to
the FDA or any other governmental regulatory agency if it is determined that
HMRI is responsible for such reported complaint and/or adverse drug reaction (or
event). Such testing shall be performed using ANDA approved testing procedures.

          IV.8 Additional Information. HMRI shall provide to Rugby in a timely
manner, but in no event less than sixty (60) days prior to the due date of
Rugby's annual report to the FDA with respect to the Products, all information
(in written form) which Rugby requests regarding the Products in order to comply
with applicable federal and state drug laws. Such information shall include,
without limitation, quantities of each Product sold. Rugby shall be responsible
for assuring that all promotional material produced by it relating to Products
comply with federal, state and local law. [Rugby shall provide to HMRI prior to
first use copies of all advertising, promotional material, labeling and other
literature used on, or in connection with, the Products.] Rugby shall provide to
HMRI a copy of such FDA annual report.

                                    ARTICLE V
                                 PRODUCT RECALLS

          V.1 Product Recalls. In the event (i) any government authority issues
a request, directive or order that Product be recalled, (ii) a court of
competent jurisdiction orders such a recall, or (iii) Rugby shall reasonably
determine that Product should be recalled, the parties shall take all
appropriate corrective actions, and shall cooperate in the investigations
surrounding the recall. In the event that Rugby determines that Product should
be recalled, Rugby shall consult with HMRI prior to taking any corrective
actions. In the event that such recall results from any cause or event other
than that arising from the defective manufacture, storage or handling (excluding
defects relating to packaging or labeling supplied by or prepared at the
direction of Rugby) of the recalled Product by HMRI, Rugby shall be responsible
for all documented out-of-pocket expenses of such recall consistent with
directions received from the appropriate governmental authority. In the event
that such recall results from any cause or event arising from the defective
manufacture, storage or handling (excluding defects relating to packaging or
labeling supplied by or prepared at the direction of Rugby), HMRI shall be
responsible for all such documented expenses. For purposes of this Agreement,
the expenses of recall shall include the expenses of notification and
destruction or return of the recalled product and all other documented
out-of-pocket costs incurred in connection with such recall, but shall not
include lost profits of either party.

          V.2 Disputes. If there is any dispute concerning which party's acts or
omissions gave rise to such recall of Product, such dispute shall be referred
for decision to an independent expert (acting as an expert and not as an
arbitrator) to be appointed by agreement between Rugby and HMRI or, in the
absence of agreement, by the President for the time being of the Pharmaceutical
Research and Manufacturers of America. The costs of such independent expert
shall be borne equally between Rugby and HMRI. The decision of such independent
expert shall be in writing and, except for manifest error on the face of the
decision, shall be binding on both Rugby and HMRI.

                  NONDISCLOSURE, CONFIDENTIALITY AND TRADEMARKS

          VII.1 Nondisclosure Obligations.

               (a)  Except  as  otherwise  provided  in  this  Agreement,  Rugby
acknowledges  that the HMRI Know-How  with which it may be supplied  pursuant to
this Agreement and HMRI  acknowledges  that the Rugby Know-How with which it may

or employees of its Affiliates or consultants and contractors  shall have access
to HMRI Know-How or Rugby Know-How,  as the case may be, on a need to know basis
and shall be subject to the same  obligations  of confidence  as the  principals

consultants and contractors are made aware of such obligations.

               (c) Both parties undertake and agree not to disclose or permit to
be  disclosed  at any time  for any  reason  whatsoever  to any  third  party or

               (d) The obligations of confidence referred to in this Section 7.1
shall not extend to any information which:

                       (i) is or becomes part of the public domain other than by

               information or its Affiliates or sublicensees, as applicable;

                      (ii)  can be  shown  by  written  documents  to have  been
               disclosed  to  the   receiving   party  or  its   Affiliates   or
               sublicensees by a third party,  provided such information was not
               obtained by such third  party  directly  or  indirectly  from the
               other party under this  Agreement  pursuant to a  confidentiality
               agreement;

                      (iii)  prior  to  disclosure  under  this  Agreement,  was
               already  in  the  possession  of  the  receiving   party  or  its

               obtained  directly or indirectly  from the other party under this
               Agreement pursuant to a confidentiality agreement;

                      (iv)  can be  shown  by  written  documents  to have  been

               documents,  subpoena,  or a civil investigative demand of a court
               or  governmental  agency;   provided  that  the  receiving  party
               notifies the other party  immediately  upon receipt  thereof (and
               provided that the disclosing party furnishes only that portion of
               the  information  which  it is  advised  by  counsel  is  legally
               required and impose such  obligations  of secrecy as are possible
               in that regard); or

reference in the usual course of business to describe the terms of this
Agreement from time to time, without the other party's consent; provided,
however, that if either party determines that excessive use of such statement is
made by the other party, then the party determined to be using such statement
excessively shall, upon notice by the other party, cease making such statement.

          VII.3 Injunctive Relief. The parties hereto understand and agree that
remedies at law may be inadequate to protect against any breach of any of the
provisions of this Article 7 by either party or their employees, agents,
officers or directors or any other person acting in concert with it or on its
behalf. Accordingly, each party shall be entitled to the granting of injunctive
relief by a court of competent jurisdiction against any action that constitutes
any such breach of this Article 7.

                                  ARTICLE VIII
             LIMITATION OF LIABILITY, INDEMNIFICATION AND INSURANCE

          VIII.1 Indemnification by Rugby. Except as otherwise specifically
provided herein, Rugby shall indemnify and maintain HMRI against all claims,
actions, costs, expenses (including court costs and legal fees on a full
indemnity basis) or other liabilities ("Liabilities") whatsoever in respect of:

               (a) any defective design product liability claim with respect to
a Product;

               (b) any negligence or willful misconduct of Rugby in relation to
the use, marketing, storage, distribution, handling or sale of Product;

               (c) any labeling of any Product to the extent that such labeling
has been supplied by or at the direction of Rugby and applied in accordance with
instructions from Rugby; and

               (d) any representation or warranty made by Rugby to its customers
or users with respect to Product, other than representations or warranties
contained in Sections 6.2, 6.3, 6.4 or 6.5.

          VIII.2 Indemnification by HMRI. Except as otherwise specifically
provided herein, HMRI shall indemnify and maintain Rugby against all Liabilities
whatsoever in respect of:

               (a)    HMRI's failure to comply with the Specifications; and

               (b)  any  negligence  or  willful   misconduct  by  HMRI  in  the
manufacture, storage, packaging, handling or shipping of Product.

          VIII.3 Indemnification Procedures. A party (the "Indemnitee") that
intends to claim indemnification under this Article 8 shall:

               (a) notify the other party (the  "Indemnitor")  of any  Liability
with respect to which the Indemnitee intends to claim indemnification as soon as
practicable after the Indemnitee becomes aware of any such Liability;



<PAGE>


               (b) permit the  Indemnitor  to assume the  defense  thereof  with
counsel mutually satisfactory to the parties; and

               (c) cooperate with the Indemnitor,  at the Indemnitor's  expense,
in the defense thereof.

          With respect to any matter for which the Indemnitor has an obligation
to indemnify the Indemnitee under this Agreement, the Indemnitee shall have the
right to participate and be represented (at the Indemnitor's expense) by legal
counsel of the Indemnitee's choice in all proceedings and negotiations, if
representation by counsel retained by Indemnitor would be inappropriate due to
actual or potential differing interests between the Indemnitee and any other
party represented by such counsel in such proceedings. The indemnity agreement
in this Article 8 shall not apply to amounts paid in settlement of any Liability
if such settlement is effected without the consent of the Indemnitor, which
consent shall not be unreasonably withheld. Failure of the Indemnitee to deliver
notice to the Indemnitor within a reasonable time after becoming aware of a
Liability shall relieve the Indemnitor of any liability to the Indemnitee
pursuant to this Article 8 in the event such delay is prejudicial to the
Indemnitor's ability to defend such action.

          VIII.4 Distribution/ Product Liability Insurance. Rugby shall obtain
and maintain in effect for the term of this Agreement, liability insurance or
indemnity policies with an insurer reasonably acceptable to HMRI, in an amount
not less than *with an indemnity to principals clause with respect to products
liability with respect to each Product and distribution of each Product, which
policies shall name HMRI as an additional insured and shall be blanket policies.
Such policies shall insure against liability on the part of Rugby and any of its
Affiliates, as their interests may appear, due to injury, disability or death of
any person or persons, or injury to property, arising from the distribution of
Products. Upon the execution of this Agreement and thereafter on January 1 each
year during the Term, Rugby shall provide to HMRI a certificate of insurance (i)
summarizing the insurance coverage, (ii) identifying any exclusions and (iii)
indicating that the terms of Rugby's insurance policies are in accordance with
this Section 9.4. Rugby shall promptly notify HMRI of any alterations to the
terms of this policy or in the amounts for which insurance is provided.



<PAGE>


          VIII.5 Manufacturer's Insurance. HMRI shall obtain and maintain in
effect for the term of this Agreement, insurance or indemnity policies with an
insurer reasonably satisfactory to Rugby, in an amount not being less than *with
an indemnity to principals clause with respect to the manufacture, storage or
handling of Product, which policies shall name Rugby as an additional insured
and shall be blanket policies. Such policies shall insure against liability on
the part of HMRI and any of its Affiliates, as their interests may appear, due
to injury, disability or death of any person or persons, or injury to property
arising from the negligence of HMRI in the manufacture of Product. Upon the
execution of this Agreement and thereafter on January 1 each year during the
Term, HMRI shall provide to Rugby a certificate of insurance (i) summarizing the
insurance coverage, (ii) identifying any exclusions and (iii) indicating that
the terms of HMRI's insurance policies are in accordance with this Section 9.5.
HMRI shall promptly notify Rugby of any alterations to the terms of the policy
or in the amounts for which insurance is provided.

          VIII.6 Product Liability Claims. As soon as it becomes aware, each
party will give the other prompt written notice of any defect or alleged defect
in a Product, any injury alleged to have occurred as a result of the use or
application of a Product, and any circumstances that may give rise to litigation
or recall of a Product or regulatory action that may affect the sale or
manufacture of a Product, specifying, to the extent the party has such
information, the time, place and circumstances thereof and the names and
addresses of the persons involved. Each party will also furnish promptly to the
other copies of all papers received in respect of any claim, action or suit
arising out of such alleged defect, injury or regulatory action.

those persons having direct knowledge of the dispute; and (iii) submission of
all documents which relate to the dispute.

          IX.5.2 Situs. The arbitration hearing shall be held in New York, New
York unless otherwise mutually agreed to in writing.

          IX.6 Procedure.

          IX.6.1 Conciliation Period. No party shall send a Notice of
Arbitration in connection with a dispute under this Article 9 unless at least
thirty (30) days prior to the date of such Notice of Arbitration, such party
shall have furnished to the other parties written notice of its intent to send a
Notice of Arbitration in connection with a dispute. During such thirty (30) day
period the Mediation Committee shall attempt in good faith to settle the dispute
in accordance with the provisions of Section 9.1 herein.



<PAGE>


          IX.6.2 Notice of Arbitration. The party seeking to institute
arbitration (hereinafter, a "Claimant") shall do so by sending the other parties
(hereinafter, each a "Respondent") a written notice of arbitration (the "Notice
of Arbitration"). The Notice of Arbitration shall set forth in detail the nature
of the dispute. The Notice of Arbitration shall also designate the arbitrator
appointed by the Claimant and set forth a full Curriculum Vitae or resume
showing that the arbitrator meets the qualifications set forth in Section 9.4.2.

          IX.6.3 Response. Within thirty (30) days after receipt of the Notice
of Arbitration, the Respondent shall send the Claimant a written Response
including any counterclaims (the "Response"). The Response shall also designate
the arbitrator appointed by the Respondent and set forth a full Curriculum Vitae
or resume showing that the arbitrator meets the qualifications set forth in
Section 9.4.2. If the Response sets forth a counterclaim, the Claimant may,
within fifteen (15) days of the receipt of the Response, deliver to the
Respondent and the arbitrators a Rejoinder (the "Rejoinder") answering such
counterclaim.

          IX.6.4 Discovery. Within sixty (60) days of the date of the Response,
each party shall submit to the other parties and to the arbitrators one (1) copy
of all documents in the possession, custody or control of the party or its
Affiliates, which are relevant to the dispute or controversy set forth in the
Notice of Arbitration, Response or Rejoinder. Within forty-five (45) days of the
date of the Response, each party shall submit to the other parties a list of all
witnesses intended to be called at the hearing. Each party shall use its
commercially reasonable good faith efforts to make available for deposition
within thirty (30) days after the delivery of the list of witnesses at each
party's respective location of its operations, all of its agents, employees, and
Affiliates who have direct knowledge of the dispute at such times and places
that shall not unreasonably disrupt the business of the other parties. The chair
of the Arbitration Panel shall determine all discovery disputes and may enforce
a decision by imposing appropriate sanctions on the non-complying party.

          IX.6.5 Record. A stenographic record of all proceedings shall be made
and oaths administered by a duly licensed and qualified court reporter. The
court reporter shall prepare five (5) copies of the stenographic record of such
proceeding and shall send one (1) copy to each of the arbitrators and to each of
the parties within seven (7) days of the relevant proceeding under this Section.

          IX.6.6 Attendance at Hearing. Each party may be represented by an
attorney at all hearings before the Arbitration Panel. The Arbitration Panel
shall have the power to require the exclusion of any witness, other than a party
or other essential person, during the testimony of any other witness. Unless the
law provides to the contrary, the arbitration may proceed in the absence of any
party or representative who, after due notice, fails to be present or fails to
obtain a postponement. An award shall not be made solely on the default of a
party; the Arbitration Panel shall require the party who is present to submit
such evidence as it may require for the making of an award.

          IX.6.7 Postponement of Hearing. The Arbitration Panel, for good cause
shown, may postpone any hearing under any of the following conditions: (i) upon
the request of a party, (ii) upon its own initiative, and (iii) upon mutual
agreement by the parties.



<PAGE>


          IX.6.8 Post-Hearing Filings. Any post-hearing briefs shall be made by
the parties to the Arbitration Panel and the other party within fourteen (14)
business days following the hearing. Each party shall be afforded an opportunity
to examine any post-hearing filings and to provide a response to the Arbitration
Panel within seven (7) business days of the receipt of a post-hearing filing.

          IX.6.9 Award Opinion. The Arbitration Panel shall issue an opinion
with respect to any dispute. The arbitrators shall issue a final decision within
one (1) month from the final hearing on any dispute. The concurrence of two (2)
arbitrators shall be sufficient for the entry of a final decision. Such opinion
shall be written in the form of "Findings of Fact" and "Conclusions of Law," and
shall include the reasons for a decision. A final decision shall be binding on
both parties.

          IX.6.10 Rehearing. The parties agree that a rehearing shall only be
allowed in the event that the chair of the Arbitration Panel is unable or
unwilling to continue performance of the duties of an arbitrator.

          IX.6.11 Confidentiality. All arbitration proceedings hereunder shall
be conducted on a confidential basis and shall be subject to the provisions of
Article 7 (Nondisclosure and Confidentiality) herein. The parties and the
arbitrators shall not disclose or otherwise make public any information revealed
during the proceedings or any final decision which may result from the
proceedings.

          IX.6.12 Waiver. Any arbitration proceeding hereunder must be
instituted within two (2) years after the controversy or claim is discovered or
reasonably should have been discovered. Failure to send a Notice of Arbitration
within such two-year period shall constitute an absolute bar to the institution
of any proceedings respecting such controversy or claim, and a waiver thereof.

          IX.7 Authority of Arbitrators.

          IX.7.1 Awards. Except as otherwise specifically provided herein, the
arbitrators shall have the power to award money damages and equitable relief
such as rescission, specific performance and injunctive relief.

          IX.7.2 Modification of Article 10. The Arbitration Panel shall not
have the power to amend, change or alter any provision of this Article 9 without
the express written consent of each party hereto.

          IX.8 Awards.



<PAGE>


          IX.8.1 Judgment. Judgment upon the award rendered by the arbitrators
shall be enforceable in any court of competent jurisdiction. Each party agrees
to submit to the personal jurisdiction of that court for purposes of the
enforcement of any such award.

          IX.8.2 Fees and Expenses. All fees of the arbitrators and the court
stenographer shall be paid by the party who does not prevail in the arbitration
as determined by the arbitrators. In the event a settlement occurs before the
issuance of a final decision, the parties shall unless otherwise agreed, each
pay an equal portion of any fees of the arbitrators and the court stenographer
and the cost of any transcripts. All other arbitration-related expenses shall be
borne by the party incurring such expenses.

          X.2 Entire Agreement; Amendment.

               (a) This Agreement, together with the Exhibits attached hereto,
embodies and sets forth the entire agreement and understanding of the parties
with respect to the subject matter herein and there are no promises, terms,
conditions or obligations, oral or written, expressed or implied, other than
those contained in this Agreement. The terms of this Agreement shall supersede
all previous oral or written agreements which may exist or have existed between
the parties relating to the subject matter of this Agreement. Neither party
shall be entitled to rely on any agreement, understanding or arrangement which
is not expressly set forth in this Agreement. Any other terms and conditions
(including without limitation any terms and conditions contained in any purchase
order or sales invoice issued pursuant to this Agreement) are hereby expressly
excluded.

               (b) This Agreement shall not be amended, modified, varied or
supplemented except in writing signed by duly authorized representatives of the
parties.



<PAGE>


          X.3 Force Majeure. If either party is prevented or delayed in the
performance of any of its obligations under this Agreement by Force Majeure (as
defined herein) and shall give written notice thereof to the other party
specifying the matters constituting Force Majeure together with such evidence as
such party reasonably can give and specifying the period for which it is
estimated that such prevention or delay will continue, the party shall be
excused from the performance or the punctual performance of such obligations as
the case may be from the date of such notice for so long as such cause of
prevention or delay shall continue. The expression "Force Majeure" shall be
deemed to include any cause substantially affecting the performance by either
party of this Agreement arising from or attributable to acts, events,
non-happenings, omissions or accidents beyond the reasonable control of the
party whose performance is so affected.

          X.4 Assignment. Neither party shall be entitled to assign its rights
and obligations hereunder without the prior written consent of the other;
provided, however, either party shall be entitled, without the prior written
consent of the other, to assign its rights and obligations hereunder to an
Affiliate, but such assignment to an Affiliate shall not relieve the assigning
party of its obligations hereunder. No permitted assignment hereunder shall be
deemed effective until the assignee shall have executed and delivered an
instrument in writing reasonably satisfactory in form and substance to the other
party pursuant to which the assignee assumes all of the obligations of the
assigning party hereunder. Any purported assignment of this Agreement in
violation of this Section 10.4 shall be void. This Agreement shall be binding
upon the successors and permitted assigns of the parties and the name of a party
appearing herein shall be deemed to include the names of its successors and
assigns.

          X.5 Headings, Interpretation. The headings used in this Agreement are
for convenience only and are not a part of this Agreement nor affect the
interpretation of any of its provisions.

          X.6 Attachments. All Exhibits referenced herein are hereby made a part
of this Agreement.

          X.7 Independent Parties. This Agreement shall not be deemed to create
any partnership, joint venture, or agency relationship between the parties. Each
party shall act hereunder as an independent contractor.

          X.8 Governing Law. This Agreement shall be governed by and construed
under the laws of the State of New York, excluding its conflict of laws
principles.

          X.9 No Waiver. Neither the failure nor delay on the part of either
party to require the strict performance of any term, covenant or condition of
this Agreement or to exercise any right or remedy available on a breach thereof
shall constitute a waiver of any such breach or of any such term or condition.
The consent to, or the waiver of, any breach, or the failure to require on any
single occasion the performance or timely performance of any term, covenant, or
condition of this Agreement shall not be construed as authorizing any subsequent
or additional breach and shall not prevent a subsequent enforcement of such
term, covenant, or condition.



<PAGE>


          X.10 Severability. In the event that any provision of this Agreement
or the application thereof to any party or circumstance shall be finally
determined by a court of proper jurisdiction to be invalid or unenforceable to
any extent, then (i) a suitable and equitable provision shall be substituted
therefore in order to carry out, so far as may be valid and enforceable, the
intent and purpose of such invalid and unenforceable provision and (ii) the
remainder of this Agreement and the application of such provision to the parties
or circumstances other than those to which it is held invalid or unenforceable
shall not be affected thereby.

          X.11 Interpretation. The parties hereto acknowledge and agree that (i)
each party and its representatives has reviewed and negotiated the terms and
provisions of this Agreement and have contributed to its revision, (ii) the rule
of construction to the effect that any ambiguities are resolved against the
drafting party shall not be employed in the interpretation of this Agreement and
(iii) the terms and provisions of this Agreement shall be construed fairly as to
each party hereto and not in favor of or against either party regardless of
which party was generally responsible for the preparation of this Agreement.

          X.12 Counterparts. This Agreement may be executed simultaneously in
two counterparts, each of which shall be deemed an original, but both of which
together shall constitute a single agreement.

          X.13 Third Party Beneficiaries. This Agreement is not intended to
confer upon any non-party rights or remedies hereunder.

          X.14 Further Assurances. Each party shall execute and deliver such
additional instruments and other documents and use all commercially reasonable
efforts to take or cause to be taken, all actions and to do, or cause to be
done, all things necessary under applicable law to consummate the transactions
contemplated hereby.

     IN WITNESS WHEREOF, the parties hereto have each caused this Agreement to
be duly executed as of the date first above written.

INDEPENDENT AUDITORS' REPORT

<PAGE>

INDEPENDENT AUDITORS' REPORT

To the Board of Directors of
   Somerset Pharmaceuticals, Inc.:

We have audited the accompanying consolidated balance sheets of Somerset
Pharmaceuticals, Inc. and subsidiaries as of December 31, 1997 and 1996, and the
related consolidated statements of income, stockholders' equity, and cash flows
for each of the three years in the period ended December 31, 1997. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all
material respects, the financial position of Somerset Pharmaceuticals, Inc. and
subsidiaries as of December 31, 1997 and 1996, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1997 in conformity with generally accepted accounting principles.

SOMERSET PHARMACEUTICALS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995
- -------------------------------------------------------------------------------


1.       PRINCIPLES OF CONSOLIDATION AND OPERATIONS

         The consolidated financial statements include the accounts of Somerset
         Pharmaceuticals, Inc. (the "Company") and its wholly owned
         subsidiaries, Somerset Pharmaceuticals Holding Company and Somerset
         Caribe, Inc. The Company is jointly owned by Mylan Laboratories, Inc.
         and Watson Pharmaceuticals, Inc. ("Watson"), with each owning 50% of
         the outstanding common stock of the Company. All significant
         intercompany accounts and transactions have been eliminated in
         consolidation. The Company, incorporated in February 1986, is engaged
         in the development, testing and marketing of drugs to be used in the
         treatment of various human disorders. Currently, the Company
         manufactures (at its facility in Puerto Rico), markets and sells
         Eldepryl, which is used as a treatment for Parkinson's Disease. The
         Company had exclusivity relating to the chemical compound Eldepryl for
         use as a treatment for late stage Parkinson's Disease through June of
         1996. In May 1996, the Company received approval from the Food and Drug
         Administration for Eldepryl capsules and withdrew the tablet form from
         the marketplace. Competitors entered the marketplace with a generic
         version of the tablet in August 1996. The loss of exclusivity and the
         introduction of competitive products could have a material impact on
         the Company's future operating results.

         The Company is party to an exclusive 14-year agreement (through
         November 22, 2003) with Chinoin Pharmaceutical Company ("Chinoin") of
         Budapest, Hungary under which Eldepryl and other new potential drugs
         resulting from Chinoin research are made available for licensing by the
         Company. The license agreement required the Company to pay royalties
         equal to 7% of net sales of Eldepryl including sub-license revenues.
         During 1996, the license agreement was amended to reduce the Eldepryl
         royalties to 3.5% of net sales subsequent to May 31, 1996. The Company
         incurred royalty expense of approximately $2,716,000, $5,917,000, and
         $8,473,000 for the years ended December 31, 1997, 1996 and 1995,
         respectively. The license agreement also requires the Company to
         purchase the main raw material used in the manufacture of Eldepryl from
         Chinoin through 1999.

2.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         a.       CASH AND CASH EQUIVALENTS - The Company generally considers
                  debt instruments purchased with a maturity of three months or
                  less and investments in money market accounts to be cash
                  equivalents.

         b.       INVESTMENT SECURITIES - The Company accounts for investment
                  securities in accordance with Statement of Financial
                  Accounting Standards ("SFAS") No. 115, "Accounting for Certain
                  Investments in Debt and Equity Securities." At December 31,
                  1997 and 1996, the investment securities were
                  available-for-sale, and there were no material unrealized
                  gains or losses. Proceeds from sales and maturities of
                  investments were $44,973,000 and $4,968,000, respectively, in
                  1997 and 1995 and realized gains or losses were not material.
                  There were no sales or maturities of investments in 1996. The
                  gain or loss on sale is based on the specific identification
                  method.

         c.       INVENTORIES - Inventories are stated at the lower-of-cost or
                  market, with cost determined on a first-in, first-out basis.

                                      -7-

<PAGE>


         d.       PROPERTY AND EQUIPMENT - Property and equipment are stated at
                  cost. Depreciation is provided over the estimated useful lives
                  of the assets by the straight-line method. Estimated useful
                  lives are five to seven years for machinery and equipment and
                  furniture and fixtures and was 35 years for the building.

         e.       INTANGIBLE ASSETS - Intangible assets are amortized on a
                  straight-line basis over 14 years.

         f.       RESEARCH AND DEVELOPMENT - Research and development costs are
                  expensed as incurred.

         g.       CONCENTRATION OF CREDIT RISK - The Company's product is sold
                  throughout the United States principally to distributors and
                  wholesalers in the pharmaceutical industry. The Company
                  performs ongoing credit evaluation of its customers' financial
                  condition and generally requires no collateral from its
                  customers.

         h.       USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS -
                  The preparation of financial statements in conformity with
                  generally accepted accounting principles requires management
                  to make estimates and assumptions that affect the reported
                  amounts of assets and liabilities and the disclosure of
                  contingent assets and liabilities at the date of the financial
                  statements, as well as the reported amounts of income and
                  expenses during the reporting period. Actual results could
                  differ from those estimates.

         i.       RECLASSIFICATIONS - Certain reclassifications have been made
                  to the 1996 financial statements to conform to the 1997
                  presentation.

5.       SUB-LICENSE OF RIGHTS

         On February 9, 1988, the Company granted a sub-license to its exclusive
         right and license to use its technology to Draxis Health Inc. (formerly
         Deprenyl Research Limited) to commercialize certain drugs in Canada for
         15 years. The Company receives a royalty of 11% of Draxis Health Inc.'s
         net sales over the license period.

         Royalty income, net of related royalty expense payable to Chinoin,
         included in other income for the years ended December 31, 1997, 1996
         and 1995 was approximately $261,000, $175,000 and $197,000,
         respectively.

6.       INTANGIBLE ASSETS

         Intangible assets primarily represent the cost of a modification to the
         terms of the Chinoin Agreement, less accumulated amortization of
         $1,639,000, and $1,446,000 at December 31, 1997 and 1996, respectively.

7.       CO-PROMOTIONAL AGREEMENT

         In 1990, the Company entered into an agreement with Sandoz
         Pharmaceuticals Corporation ("Sandoz") to co-promote the product
         Eldepryl. The agreement required Sandoz, among other things, to expend,
         at a minimum, a predetermined amount for advertising during each year
         of the agreement. In December 1994, the Company amended its
         co-promotional agreement with Sandoz. The amended agreement eliminated
         certain residual period payments to Sandoz, shortened the term to March
         31, 1996, eliminated certain sales force detail requirements and
         required certain payments to be made to the Company if a predetermined
         level of sales was not achieved.

         During 1995 the Company entered into an agreement with CoCensys, Inc.
         ("CoCensys") for the promotion of Elderpryl. The agreement was
         effective January 1, 1996 and had an initial term of two years. Under
         the terms of the original agreement, the Company would have compensated
         CoCensys, based on a predetermined formula that considered both the
         number of new prescriptions written and the net sales dollars achieved
         in each quarter. During 1996 and 1997, the agreement was modified with
         respect to term, new prescriptions and detail calls. During 1997,
         CoCensys was acquired by Watson. In January 1998, the Company entered
         into an agreement to pay Watson $4.8 million for the promotion and
         marketing of Elderpryl during 1998.

         During 1997, 1996 and 1995, the Company expensed (net of any payments
         required to be made to the Company by Sandoz in 1995) $3,800,000,
         $1,230,000 and $5,304,000, respectively, pursuant to these agreements.
         Additionally, certain co-promotional fees paid by Sandoz at the
         commencement of the 1990 agreement were recognized ratably by the
         Company during the term of the agreement (six years, expiring on March
         31, 1996), and certain costs associated with the procurement,
         negotiating and execution of the agreement by the owners of the Company
         were incurred by the Company in approximately the same amount.

8.       OTHER INCOME

         In November 1994, the Company prevailed in litigation it brought
         against foreign defendants who were selling and marketing chemical
         compounds similar to Eldepryl without FDA approval. In late 1997, a
         final judgment was rendered by the United States Federal District
         Court. In November 1997, the Company received and recorded as other
         income approximately $1,225,000 for settlement of the litigation and
         reimbursement of related costs.

                                      -9-

<PAGE>

         During November 1997, the Company sold its research and development
         facility and related equipment with a net book value of approximately
         $3,422,000 for $3,000,000. The resulting loss of $422,000 is recorded
         as a reduction in other income. The Company financed in the form of a
         note $1,000,000 of the sales price. The note receivable is
         collateralized by the facility and will be collected in 60 monthly
         installments bearing interest at 8%. Current and non-current portions
         are included with prepaid expenses and other current assets and other
         assets, respectively, in the consolidated balance sheet at December 31,
         1997.

9.       INCOME TAXES

         The income tax provision consists of the following for the years ended
December 31, 1997, 1996 and 1995:

         Deferred income taxes reflect the net tax effects of temporary
         differences between the carrying amounts of assets and liabilities for
         financial reporting purposes and the amounts used for income tax
         purposes. The tax effects of significant items comprising the Company's
         deferred taxes (which are included in "Other Assets" in the balance
         sheet) at December 31, 1997 and 1996 are as follows:

         The Company had sales to certain customers which individually exceeded
         10% of sales. In 1997 sales to five major customers were $15,878,000,
         $13,498,000, $11,427,000, $8,658,000 and $7,746,000, respectively. In

12.      EMPLOYEE BENEFIT PLANS

         The Company has a defined contribution profit sharing plan covering
         substantially all employees. Contributions are made at the discretion
         of the Board of Directors. Additionally, during 1994, the Company
         initiated a deferred compensation plan for certain key employees.
         During 1997, the Company terminated the deferred compensation plan.
         During 1997, 1996 and 1995, the Company recorded expense of $-0-,
         $954,000 and $83,000, respectively, under these plans. The Company
         expects to terminate the defined contribution profit sharing plan
         during 1998 without significant impact on 1998 operating results.

13.      CONTINGENCY

         In connection with an examination of the Company's Federal tax returns
         for the three years ended December 31, 1995, representatives of the
         Internal Revenue Service (the "Service"), in June 1997, issued to the
         Company a report that contains proposed adjustments to the Company's
         use of tax credits under Internal Revenue Code section 936.

         Under the proposed adjustments, the Company could be subject to
         approximately $13 million of additional income tax and interest charges
         that have not been accrued at December 31, 1997.

         Management believes that the Company has met all of the requirements to
         qualify for the tax credits available under Internal Revenue Code
         section 936, and intends to vigorously defend its position on this
         matter.
