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>   4

         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>   5

         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.

<PAGE>   6

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. 
    

         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.

   
         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.
    

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>   7

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>   8

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>   9

(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.

   
         At the conclusion of an inspection during November 1997, the Company 
received a Form FD 483 ("FD483") from the FDA listing several perceived
deficiencies in specifications and control procedures for the oldest of the
Company's approved products. The Company's response to the FD 483 demonstrated
that additional specifications and procedures had been or were being developed.
On January 28, 1998, before the Company's response was evaluated, the FDA issued
a Warning Letter that cited the need to take corrective actions. Thereafter,
the Company provided a written response to the Warning Letter and met with the
FDA to discuss the FD 483 observations and the Warning Letter. Based upon
discussions with the FDA, the Company believes that all issues raised by the
FDA have been resolved or will be resolved satisfactorily within a time period
agreed to with the FDA.
    

                                        9


<PAGE>   10

         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 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.

   
         Beginning in late 1997, a number of product liability suits were filed
against Rugby and numerous manufacturing defendants for personal injuries 
arising out of the use of phentermine hydrochloride. The Plaintiffs allege
various injuries, ranging from memory loss and anxiety to heart damage and
death. To date, twenty-six cases have been filed in state and federal courts in
eleven different states. Most of the cases involve multiple plaintiffs, and six
of the complaints were filed as class actions. The Company believes that it will
be fully indemnified by Hoechst Marion Roussel, Inc. ("HMRI") for the defense
and liability of these cases, and HMRI is currently controlling the defense of
all these matters. Additionally, it is Rugby's position that it has recourse for
liability from the manufacturing defendants in these cases.
    

         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.

                        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.

                   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:

                   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.

         RECENT ACCOUNTING PRONOUNCEMENTS

         In June 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 130 ("SFAS 130"), "Reporting Comprehensive
Income". SFAS 130 establishes standards for the reporting and disclosure of
comprehensive income (revenues, expenses, gains and losses) in a full set of
general-purpose financial statements.

         The Financial Accounting Standards Board issued Statement of Financial
Accounting Standards No. 131 ("SFAS 131"), "Disclosures about Segments of an
Enterprise and Related Information," in June 1997. SFAS 131 establishes
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.

         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.

         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:

         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
investments in joint ventures.

         Reconciliations between the statutory federal income tax rate and the
Company's effective income tax rate were as follows:

         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
123"), in 1996. As permitted by SFAS 123, the Company measures compensation cost
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 weighted average fair value of the options have been estimated on
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.

         The Company had notes receivable due from related parties in the
amounts of $2.0 million and $2.4 million at December 31, 1997 and 1996,
respectively. The $2.0 million note will mature in April 1998; the $2.4 million
note was repaid during 1997.

9.       COMMITMENTS AND CONTINGENCIES

         FACILITY AND EQUIPMENT LEASES

         The Company has entered into operating leases for certain facilities
and equipment. The terms of the operating leases for the Company's facilities
require the Company to pay property taxes, normal maintenance expenses and
maintain minimum insurance coverage. Total rental expense for operating leases
in 1997, 1996 and 1995, including rent paid to related parties, was $2.5
million, $2.1 million and $2.0 million, respectively.

         At December 31, 1997, future minimum lease payments under all
noncancelable operating leases consisted of the following:

         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.

                          CONFIDENTIAL TREATMENT - NOTED BY * AND STRIKE-THROUGH



                            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").

                                 R E C I T A L S


         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.

                               A G R E E M E N T S


         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 Seventy
Million Dollars ($70,000,000) (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 $39,000,000; or (b) reduced by the amount by which $38,000,000 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.

                          CONFIDENTIAL TREATMENT - NOTED BY * AND STRIKE-THROUGH
<PAGE>   2
                          CONFIDENTIAL TREATMENT - NOTED BY * AND STRIKE-THROUGH

         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 $39,000,000, 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 $39,000,000 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 Medicaid
rebates included as an accrued liability in the Interim Financial Statements and
the reserve relating to the claim by the Department of Defense (the "Dapa
Reserve") included in the Interim Financial Statements shall not have been
reversed from July 31, 1997 through the Closing Date if the effect of such
reversal would be to increase the consolidated net income of the Company and its
Subsidiaries; and (e) the assets and liabilities reflected on the Closing
Balance Sheet shall exclude (i) all intangible assets of the Company or any of
its Subsidiaries; (ii) any asset or liability relating to Chelsea Laboratories
Caribe, Inc. ("Caribe"); (iii) any asset or liability relating to the Monroe,
North Carolina manufacturing facility owned by Chelsea Laboratories, Inc.; and
(iv) the amounts referenced in Sections 6 and 9(a) of the Novopharm Agreement
(as defined herein) and any

amounts relating to purchase credits or similar adjustments due or claimed to be
due to the Company or its Subsidiaries from Novopharm pursuant to the terms of
the Novopharm Agreement, and any amounts relating to damages owed or claimed to
be owed by Novopharm to the Company or its Subsidiaries due to Novopharm's
breach of such agreement, other than claims relating to shortages of product or
defective goods. 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 Notice within the Dispute Period, setting forth in reasonable
detail the elements and amounts with which it disagrees. Within thirty (30) days

resolve such Dispute and agree in writing upon the final content of the disputed
Closing Balance Sheet.

such Dispute as soon as practicable. In the event Arthur Andersen LLP is

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

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.

laws of the State of Nevada and has all requisite power and authority to (i) own

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

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

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"),

         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.

or applicants acting on its behalf as of the date of this Agreement, the Company
and its Subsidiaries have complied in all material respects with the
requirements of 21 U.S.C. Sections 355 and 357 and 21 C.F.R. Parts 312,
314 and 430 et. seq. and has provided, or will provide, all additional
information and taken, or will take, all additional action requested by the FDA
in connection with the application.

         3.10 Books and Records. The Company's and its Subsidiaries' books,
accounts and records are, and have been, in all material respects, maintained in
the Company's and its Subsidiaries usual, regular and ordinary manner, in
accordance with GAAP, and all material transactions to which the Company or any
of its Subsidiaries is or has been a party are properly reflected therein.

         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
the Company nor any of its Subsidiaries has reduced the amount of the Medicaid
rebates reflected as an accrued liability in its books and records or its
consolidated financial statements or the Dapa Reserve reflected as an accrued
liability in its books and records or its consolidated financial statements if
the effect of such reduction would be to increase the consolidated net income of
the Company and its Subsidiaries.

         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
31, 1997, is or was subject to any material counterclaim or set off. All of such
trade receivables arose out of bona fide, arms-length transactions for the sale
of goods or performance of services, and to the Company's 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. Since July 31,
1997, there has not been a material write-down or write-off of the Company's
aggregate trade receivables or a material adverse change in the aging thereof.

         3.13 Inventory. All inventory of the Company or any of its Subsidiaries
which is held for sale or resale, including raw materials, work in process and
finished goods (collectively, "Inventory"), consists of items of a quantity and
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
Inventory are, located at the Real Estate (as defined herein), the Leased
Premises (as defined herein) or the Company's or its Subsidiaries' manufacturing
locations.

         3.14 Bank Accounts. The Disclosure Statement contains a list showing:
(a) the name of each bank, safe deposit company or other financial institution
in which the Company or any of its Subsidiaries has an account, lock box or safe
deposit box; (b) the names of all persons authorized to draw thereon or to have
access thereto and the names of all persons and entities, if any, holding powers
of attorney from the Company or any of its Subsidiaries; and (c) all instruments

and binding obligations of the Company or its Subsidiaries and in full force and
effect, and no default by the Company or its Subsidiaries, or, to the knowledge
of the Company, any other party thereto has occurred and is continuing
thereunder. The Disclosure Statement lists all properties and assets used by the
Company or any of its Subsidiaries in connection with the operation of their
respective businesses which are held under any lease or under any conditional
sale or other title retention agreement to the extent the Company or its
Subsidiaries remaining obligations under any such lease or agreement exceeds
$50,000. Except for such assets and facilities as are immaterial to the business
of the Company or its Subsidiaries, all tangible assets and facilities of the
Company and its Subsidiaries are in good operating condition and repair
(ordinary wear and tear excepted) and, in the aggregate with the intangible
assets of the Company, are sufficient to conduct the business of the Company and
its Subsidiaries as previously conducted prior to the date hereof.

         3.17     Real Estate; Leased Premises.

         (a) Neither the Company nor any of its Subsidiaries owns any real
estate, or has the option to acquire any real estate (the "Real Estate"). The
definition of Real Estate shall not include the facility located in Monroe,
North Carolina owned by Chelsea Laboratories, Inc. or any real estate owned by
Caribe. The Disclosure Statement accurately sets forth the street addresses of
the Real Estate and the legal descriptions of the Real Estate. Either the
Company or one of its Subsidiaries holds fee simple title to the Real Estate,
subject only to real estate taxes not delinquent and to covenants, conditions,
restrictions and easements of record which are set forth in the Disclosure
Statement, none of which makes title to the Real Estate unmarketable and none of
which are violated by the Company or its Subsidiaries or interfere with the
Company's or its Subsidiaries use thereof. The Real Estate is not subject to any
leases or tenancies. None of the improvements comprising the Real Estate or the
businesses conducted or proposed to be conducted by the Company or its
Subsidiaries thereon, are, to the Company's knowledge, in violation of any
material use or occupancy restriction, limitation, condition or covenant of
record or any zoning or building law, code, ordinance or public utility easement
or any other applicable law. No material expenditures are required to be made
for the repair or maintenance of any improvements on the Real Estate or for the
Real Estate to be used for its intended purpose.

record or any zoning or building law, code or ordinance, public utility or other
easements or other applicable law, except for violations which do not have a
Company Material Adverse Effect or materially interfere with the conduct of the
business of the Company or its Subsidiaries. No material expenditures are
required to be made for the repair or maintenance of any improvements on the
Leased Premises or for the Leased Premises to be used for its intended purpose.
All options in favor of the Company or its Subsidiaries to purchase any of the
Leased Premises, if any, are in full force and effect.

         (c) To the Company's knowledge, the improvements on the Real Estate,
the Leased Premises and the Company's and its Subsidiaries Manufacturing

         (d) Neither the Company nor any of its Subsidiaries is a party to, or
bound by, any unexpired, undischarged or unsatisfied written or oral contract,
agreement, indenture, mortgage, debenture, note or other instrument under the

with respect to or affecting the Company's or its Subsidiaries' respective
operations, businesses, products, sales practices or financial condition, or
related to the consummation of the transactions contemplated hereby or by the

of Code section 401(a) to the extent any Pension Plan is intended to conform to
that section), other Federal statutes, state law (including, without limitation,
state insurance law) and the regulations and rules promulgated thereunder. A
favorable determination as to the qualification under Section 401(a) of the Code

Company has not failed to make any contributions or to pay any amounts due and
owing to any Plan, as required by the terms of any such Plan or ERISA or any
other applicable law. There has been no reduction or curtailment of accrued
benefits with respect to any of the Plans which did not comply with the terms of
the Plan, the Code or ERISA. Full payment has been made or such amount has been

a "Genericized Product") by Watson or any of its Subsidiaries if Watson or any
of its Subsidiaries has acquired such distribution rights from the holder or
licensor of the NDA relating to such branded product so long as the Genericized
Product does not replace an AB rated equivalent product or an AB rated
equivalent Product being distributed by Watson or any of its Subsidiaries at the
time of the acquisition of such Genericized Product by Watson or any of its
Subsidiaries; (iv) the distribution and/or sale of any of the Products by Watson
or any of its Subsidiaries; (v) the distribution and/or sale by Watson or any of
its Subsidiaries of products distributed in packaging that was not historically
available through the Company's or any of its Subsidiaries' distribution
channels, including, without limitation, specially packaged unit dose products;
(vi) the distribution and/or sale of ranitidine (Rx or OTC) or Ciprofloxacin by
Watson or any of its Subsidiaries; and (vii) the distribution and/or sale of any
pharmaceutical products by Watson or its Subsidiaries in any country other than
the United States ((i) through (vii) above being collectively referred to herein
as the "Watson Products").

         (c) "Distribution Net Profits" means the actual gross invoice price of
each product sold through the Distribution Business as determined using the
accrual basis of accounting in accordance with GAAP applied in a manner
consistent with Watson's customary practices, less the sum of (i) any and all
promotional allowances, rebates, quantity and cash discounts, and other usual
and customary discounts to customers accrued in the ordinary course of business,
in accordance with historical practice and GAAP and current industry trends;
plus (ii) amounts repaid or credited by reason of rejections or returns of
goods; plus (iii) retroactive price reductions; plus (iv) 50% of the reasonable
allowance for doubtful accounts accrued in the ordinary course of business, in
accordance with historical practice and GAAP; plus (v) the aggregate amount paid
by Watson or any of its Subsidiaries to any third party to purchase products
sold through the Distribution Business; plus (v) all royalties paid by Watson or
any of its Subsidiaries with respect to the Distribution Business; provided,
however, that the calculation of Distribution Net Profits shall exclude the
impact of unusual and non-recurring items as determined in accordance with GAAP
applied in a manner consistent with Watson's customary practices.

         (d) "Manufacturing Cost" means, with respect to a Product, Watson's or
any of its Subsidiaries' Direct Material Costs, Direct Labor Costs and Overhead
attributable to such Product. "Direct Material Costs" shall mean reasonable
costs incurred in purchasing raw materials (without deduction for waste),
including sales and excise taxes imposed thereon, and all costs of packaging
components. "Direct Labor Costs" shall mean the reasonable cost of temporary and
full-time employees engaged in manufacturing activities who are directly
involved in product manufacturing and packaging and in quality assurance/quality
control. "Overhead" allocated to a Product means indirect costs associated with

of Watson's or its Subsidiaries' Manufacturing Costs shall be made in accordance
with standard cost and reasonable cost accounting methods in accordance with
GAAP, applied in a manner consistent with Watson's

                          CONFIDENTIAL TREATMENT - NOTED BY * AND STRIKE-THROUGH

customary practices. In the case of Products or Distributed Ranitidine
manufactured in whole or in part by a third party or third parties on behalf of
Watson or its Subsidiaries, "Manufacturing Cost" shall include all costs paid to
such third party or third parties by Watson or its Subsidiaries in order to
complete the Products or Distributed Ranitidine, as the case may be, including,
without limitation, costs related to the purchase of labels. With respect to
products purchased by Watson or one of its Subsidiaries in finished package
form, only the costs paid by Watson or one of its Subsidiaries to such third
party to purchase such products shall be included in the calculation of
Manufacturing Costs with respect to such product. Notwithstanding the foregoing,
Manufacturing Costs shall not include costs relating to distribution expenses.

         (e) "Net Profits" means for each Product and for Distributed
Ranitidine, the amount by which Net Sales with respect to each Product or
Distributed Ranitidine, as the case may be, exceeds Cost of Sales with respect
to each Product or Distributed Ranitidine, as the case may be; provided,
however, that the calculation of Net Profits shall exclude the impact of unusual
and non-recurring items as determined in accordance with GAAP applied in a
manner consistent with Watson's customary practices.

         (f) "Net Sales" shall be determined using the accrual basis of
accounting in accordance with GAAP applied in a manner consistent with Watson's
customary practices. Net Sales means the actual gross invoice price of each
Product or Distributed Ranitidine, as the case may be, sold by Watson or any of
its Subsidiaries, regardless of whether such Product is distributed or
manufactured, less (i) any and all promotional allowances, rebates, quantity and
cash discounts, and other usual and customary discounts to customers accrued in
the ordinary course of business, in accordance with historical practice and GAAP
and current industry trends, (ii) amounts repaid or credited by reason of
rejections or returns of goods, (iii) retroactive price reductions, and (iv) 50%
of the reasonable allowance for doubtful accounts accrued in the ordinary course
of business, in accordance with historical practice and GAAP.

         (g) "Product" or "Products" means the products listed on Exhibit H
attached hereto.

         6.2      Sale of Product.

         (a) Watson and its Subsidiaries shall sell each Product and each
product included in the Distribution Business at prices to be determined by
Watson in its sole and absolute discretion. Watson and its Subsidiaries agree to
use commercially reasonable good faith efforts to develop, market, manufacture
or have manufactured, as the case may be, and sell each Product or each product
included in the Distribution Business, unless it becomes commercially unfeasible
for Watson or its Subsidiaries to continue to develop, market, manufacture or
have manufactured such product. Notwithstanding the foregoing, such efforts
shall be used without regard to the payment to be made pursuant to Section 6.5
of this Agreement.

         (b) During calendar years 1998, 1999 and 2000, Watson and its
Subsidiaries shall record sales of Products or products included in the
Distribution Business according to their usual,

regular and ordinary course in substantially the same manner as recorded in the
past. Without limiting the foregoing, Watson and its Subsidiaries shall not (i)
take any actions outside the ordinary course of business to book sales in the
year 1998 or defer the recognition of sales to the year 2000 that would, in each
case, otherwise be booked in 1999; or (ii) conduct promotional sales programs
during the last quarter of 1998 or 1999 or during the first quarter of 2000, in
each case, outside the ordinary course of business that would have the effect of
increasing sales in 1998 or 2000 and decreasing sales in 1999.

         (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)
received by Watson or its Subsidiaries on the bundled sale of Products or
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 ranitidine (Rx or OTC) as a distributed
(rather than a manufactured) product through goods purchased from Novopharm or
any other third party ("Distributed Ranitidine"), within forty-five (45) days
after the end of each calendar quarter, Watson shall 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 Distributed Ranitidine 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
Distributed Ranitidine sold by Watson and its Subsidiaries for the period
covered by such Quarterly Report.

         6.4      Royalty Payment on Distributed Ranitidine.

         (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 Distributed Ranitidine (Rx) and
Distributed Ranitidine (OTC), respectively, during the calendar quarter covered
by the Quarterly Report; provided, however, that, in lieu of the foregoing
royalty, until the earlier of the date upon which the Ranitidine 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 Distributed Ranitidine during the period beginning
on the Closing Date and ending on December 31, 1998. For purposes of this
Agreement, the "Ranitidine Payment" shall mean an amount equal to $15,000,000,
which amount is comprised of the sum of (i) any amount of Net Profit earned by
the Company or one of its Subsidiaries on the sale of Distributed Ranitidine
during the period from the opening of business

                          CONFIDENTIAL TREATMENT - NOTED BY * AND STRIKE-THROUGH

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 Novopharm Agreement, or any other amounts from Novopharm due to
the breach of such agreement by Novopharm 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 Ranitidine 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 ranitidine
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 Novopharm pursuant to Section 4 of the Novopharm Agreement.

         (d) Watson and its Subsidiaries shall sell Distributed Ranitidine 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 ranitidine as a
manufactured product, Watson and its Subsidiaries agree to use commercially
reasonable good faith efforts to market and sell Distributed Ranitidine, unless
it becomes commercially unfeasible for Watson or its Subsidiaries to continue to
market and sell Distributed Ranitidine. 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 Distributed Ranitidine
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 Distributed Ranitidine multiplied by the following
fraction, the numerator of which is equal to the number of units of Distributed
Ranitidine 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 Distributed Ranitidine) or service included in such bundled sale
multiplied by the respective standard invoice unit price thereof.

         (e) To the extent that Watson or one of its Subsidiaries actually
receives any amounts from Novopharm relating to purchase credits on any units of
Distributed Ranitidine sold by the Company or its Subsidiaries and such purchase
credits relate in whole or in part to the period of time prior to August 11,
1997, Watson or one of its Subsidiaries shall pay such amount of the credits
which relate to the sale of Distributed Ranitidine made by the Company or its
Subsidiaries prior to August 11, 1997 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
March 31, 2000, 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 1999; and (ii) the Distribution Net Profit during calendar year
1999 (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 $150,000,000:

                  (i) if the Upside Net Profits are less than or equal to $*,
zero dollars ($0.00);

                  (ii) if the Upside Net Profits are less than or equal to $*
but greater than $*, (A) four (4); multiplied by (B) the Upside Net Profits less
$*;

                  (iii) if the Upside Net Profits are less than or equal to $*
but greater than $*, $20,000,000 plus the following: (A) three (3); multiplied
by (B) the Upside Net Profits less $*;

                  (iv) if the Upside Net Profits are less than or equal to $*
but greater than $*, $35,000,000 plus the following: (A) two and one-half (2.5);
multiplied by (B) the Upside Net Profits less $*; and

                  (v) if the Upside Net Profits are greater than $*, $47,500,000
plus the following: (A) two (2); multiplied by (B) the Upside Net Profits less
$*.

         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

<PAGE>   43
                          CONFIDENTIAL TREATMENT - NOTED BY * AND STRIKE-THROUGH

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 1999 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 1999 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 1999 shall be deemed to be equal to the sum of (x)
the Distribution Net Profits derived by

                          CONFIDENTIAL TREATMENT - NOTED BY * AND STRIKE-THROUGH

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 1999; 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, 1999, (i) all Net Profits received from the
commercial sale of such Product during calendar year 1999 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,
1999, 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
1999 shall be equal to the Net Profit derived by Watson and its Subsidiaries
from the sale of such Product during calendar year 1999 multiplied by the
following fraction: the numerator of which is equal to 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, 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 1999 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 1999 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, 1999, 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, 2000 (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

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 Distributed Ranitidine 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

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.

         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

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.

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

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

entitled to indemnification from another party hereto pursuant to this Article

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

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

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

Section 7.5, Watson shall indemnify, save and keep Parent and Seller and their
respective successors and permitted assigns ("Seller Indemnitees"), forever
harmless against and from all Damages sustained or incurred by any Seller

any representation and warranty made by Watson to Seller and Parent herein or in
any Watson Ancillary Document; and (b) any breach by Watson of, or failure by
Watson to comply with, any of the covenants or obligations under this Agreement
or the Watson Ancillary Documents to be performed by Watson (including, without
limitation, its obligations under this Article VII).

         7.5      Limitation on Indemnification Obligations.

<PAGE>   51
                          CONFIDENTIAL TREATMENT - NOTED BY * AND STRIKE-THROUGH

the Closing until the expiration of the applicable statute of limitations (the

Survival Period.

                  (b) (i) the Watson Indemnitees shall only be entitled to

aggregate claims for indemnification exceed $1,250,000, 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 $22,500,000 in the
aggregate.

                  (c) (i) the Seller Indemnitees shall only be entitled to
indemnification pursuant to Section 7.4 hereof once the Seller Indemnitees'

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 $22,500,000 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>   52
                          CONFIDENTIAL TREATMENT - NOTED BY * AND STRIKE-THROUGH

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

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.

                                  ARTICLE VIII

                                   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

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,

consent of HMRI, to entities which are not Affiliates of Rugby. Rugby will
provide a copy of all such sublicenses to HMRI.

                  II.3 RIGHT OF FIRST REFUSAL. In the event HMRI determines (in
its sole discretion) to launch a generic version of *, HMRI will provide Rugby
the right of first refusal on terms proposed by HMRI in good faith as terms
which would be acceptable to an unaffiliated third party, upon which HMRI would
supply a generic version of * (the "Terms"). Concurrently with the delivery of
the Terms, HMRI shall deliver to Rugby all reasonably sufficient information in
its possession relating to the sale of * reasonably requested by Rugby and
required 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 acceptance shall be in writing in accordance with the provisions of
Section 11.1 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, HMRI may not enter into an agreement with any other party on terms and
conditions less favorable in the aggregate to HMRI than the Terms (such less
favorable in the aggregate terms and conditions being referred to as the "Other
Party Terms"), without first offering to enter into an agreement with Rugby on
the Other Party Terms. Upon receipt of such offer, Rugby shall keep the Other
Party Terms confidential and shall have five (5) business days to accept the
Other Party Terms, which acceptance shall be in writing in accordance with the
provisions of Section 11.1 herein. In the event Rugby does not accept such Other
Party Terms within such time period, HMRI may enter into an agreement with any
other party on terms and conditions at least as favorable in the aggregate to
HMRI as the Other Party Terms; provided, further, that in the event that HMRI
offers to enter into an agreement with any other party with respect to a generic
version of * on terms and conditions less favorable in the aggregate to HMRI
than the then existing Other Party Terms, HMRI shall first offer such terms and
conditions to Rugby and Rugby shall keep such terms and conditions confidential
and shall have five (5) business days to accept such terms and conditions
offered by HMRI, which acceptance shall be in writing in accordance with the
provisions of Section 11.1 herein. The provisions of this Section 2.3 shall
terminate upon HMRI entering into an agreement with another party with respect
to a generic version of *, in accordance with this Section 2.3. Notwithstanding
the foregoing, if the other party accepting the Terms or the Other Party Terms,
as the case may be, is an Affiliate of HMRI, which in lieu of launching a
generic version of *, transfers such distribution rights to a third party and
such transfer is on terms less favorable in the aggregate to the Terms or the
Other Party Terms, as the case may be, such new terms shall be offered to Rugby.
Upon receipt of such offer, Rugby shall keep such terms confidential and shall
have five (5) business days to accept such terms, which acceptance shall be in
writing in accordance with the provisions of Section 11.1 herein.

                  II.4 ACTIVE INGREDIENT SUPPLY AGREEMENT. Upon the reasonable
written request of Rugby, HMRI agrees to enter into discussions with Rugby
regarding the terms and conditions upon which HMRI and Rugby could enter into an
active ingredient supply agreement; provided, however, that Rugby acknowledges
and agrees that HMRI is under no obligation to enter into such active ingredient
supply agreement.

                  III.1 PURCHASE AND SALE. Pursuant to the terms and conditions
of this Agreement, HMRI agrees to manufacture for Rugby, during the Term, the

of Products to fulfill its obligations hereunder.

                  III.2 SHELF LIFE. HMRI will ship Product to Rugby with a shelf
life at least equal to the requisite regulatory shelf life for such Product

                  III.3 PRODUCT EXPANSION OR ABANDONMENT; SALE OF PRODUCT.

                  (a) Product Expansion or Abandonment. Exhibit A attached
hereto sets forth the initial list of Products subject to the terms of this
Agreement, and may only be amended from time to time as provided in this Section
3.3. Additional generic versions of products in finished dosage forms and in
package sizes (SKU) pursuant to HMRI new drug applications may be added to the
terms of 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
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 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
Agreement and again become subject to this Agreement if Rugby consents in
writing to such inclusion; provided, however, in the event HMRI chooses not to
manufacture such Product, HMRI agrees to transfer the manufacturing rights in
accordance with the provisions of Section 3.3(c) herein with respect to such
Product (except with respect to the Proprietary Products) to Rugby. In addition,
Product may be abandoned by either party hereto upon two (2) years written
notification by such party to the other, 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, 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

                          CONFIDENTIAL TREATMENT - NOTED BY * AND STRIKE-THROUGH

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. Rugby
acknowledges that the exclusive royalty right and license to promote,
distribute, market and sell a particular Product shall terminate upon an
abandonment of such Product by Rugby. Rugby shall be deemed to have abandoned a
Product if its forecasted purchases of such Product is equal to zero for four
(4) consecutive short-term forecasts (under Section 3.5(b) hereof) with respect
to the first three (3) months of each such forecast.

                  Subject to the availability of active ingredients and
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 HMRI Know-How, which expenses will be
reimbursed by Rugby within thirty (30) days after the completion of such
transfer.

                  III.4 LABELING AND PACKAGING. Rugby shall be responsible for
all costs of developing, packaging and labeling for the Product, and shall
provide HMRI all art work to be applied to each Product, which shall be
consistent with the FDA approved labeling for the Products. Rugby shall provide
such information pursuant to this Section 3.4 to HMRI a sufficient period of
time in advance of delivery requirements for the Products set forth in this
Agreement.

                  III.5 FORECASTS.

                  (a) Long-Range Forecasts. Upon execution of this Agreement and
by October 1 of each year thereafter, Rugby shall provide HMRI with a forecast
of the quantities of each Product, by package size (SKU) and finished dosage
form, that Rugby intends to order during the three (3) year period commencing
with the following calendar year. The parties acknowledge that such forecasts
shall represent reasonable best faith estimates, not purchase commitments.

                  (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 calendar quarter, 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 twelve (12) month period commencing with
that calendar quarter, stipulating periodic delivery requirements. The first
three months of such forecast shall constitute a 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 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 quarters as
follows:

                  III.6 ORDERS. Rugby acknowledges that each Product is produced
in full lot quantities, as set forth on Exhibit A attached hereto. At least *
days prior to the delivery date specified in each respective order, Rugby shall
place its purchase order with HMRI for each Product in full lot quantities, by
package size (SKU) and finished dosage form. Unless otherwise specified in
writing, all orders placed by Rugby with HMRI hereunder shall be addressed as
follows:

                           Hoechst Marion Roussel, Inc.
                           2110 East Galbraith Road

                           Cincinnati, OH 45215-6800
                           Attn:  Mr. Ron Schallick

                  Such orders shall specify in each three month period an
aggregate quantity of each Product, by package size (SKU) and finished dosage
form, which is at least as great as the amount of such Product required to be
purchased by Rugby pursuant to Section 3.5. HMRI may reject any portion of an
order which exceeds *% of the most current forecast underlying such order, or
may reject any order which (i) except as otherwise provided in Section 3.14
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 11.3. 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 3.7 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, provided that such Product meets the Specifications. In
no event shall the use of any form of order acknowledgment, purchase order,
shipping document, 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, which forecast is attached hereto as Exhibit C, will be binding
on the parties after the execution of this Agreement and such Products shall be
purchased pursuant to the terms of this Agreement.

                  III.7 DELIVERY. Delivery terms shall be F.O.B. HMRI's
manufacturing facility. HMRI shall ship Product in accordance with Rugby's
purchase order form or as otherwise directed by Rugby in writing. Title to any
Product purchased by Rugby shall pass to Rugby upon the earlier of (i) a common
carrier accepting possession or control of such Product or (ii) the passage of
such Product from the loading dock of HMRI's facility to Rugby or its agent.

                  III.8 SHORTAGES/ REJECTED GOODS.

                  (a) Shortages. Rugby shall notify HMRI in writing of any
shortage in quantity of any shipment of Product within the earlier of (i) ten
(10) business days after discovery of such shortage and (ii)

the shelf life of such Product, but only to the extent that such Product is in
the possession of Rugby. Such notification shall specify the package size (SKU)
and finished dosage form of such Product. Rugby shall notify HMRI in writing of
any shortage in quantity of any shipment of Product that is not within its
possession within the earlier of (i) ten (10) business days after discovery and
(ii) the shelf life of such Product, and shall provide documentation reasonably
satisfactory to HMRI demonstrating such shortage existed while such Product was
in the possession of Rugby. In the event of such shortage (and the reasonable
satisfaction in HMRI's determination of documentation if Product is not in the
possession of Rugby), HMRI shall make up the shortage within seven (7) business
days if replacement Product stock is available, or, if no such replacement stock
is available, as soon as reasonably practicable after receiving such notice, at
no additional cost to Rugby.

                  (b) Rejected Goods. Rugby shall notify HMRI in writing of any
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
that such Product so fails to meet the Specifications and (ii) the shelf life of
such Product, which notification shall specify the package size (SKU) and
finished dosage form of such Product. Subject to the provisions of Section
3.8(c) herein, HMRI shall replace such Product that fails to meet the
Specifications within ten (10) business days at no additional cost to Rugby. The
provisions of this Section 3.8(b) shall not apply to Product damaged in transit.

                  (c) Disputes. In the event of a conflict regarding whether
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
that the Product in question fails to meet the Specifications, HMRI shall
replace such Product at no additional cost to Rugby within ten (10) business
days after receipt of such results. In the event the test results indicate that
the Product in question does meet the Specifications, Rugby shall pay all
additional shipping and transportation costs incurred as a result of the
conflict.

                  (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
in whole or in part, then HMRI shall give written notice of such inability to
Rugby within ten (10) days of receipt of such forecast or firm order. HMRI and
Rugby shall meet within ten (10) days of such written notice to consider
alternatives for meeting Rugby's requirements for Product, including but not
limited to the sharing of the cost to expand HMRI's manufacturing capacity.

                          CONFIDENTIAL TREATMENT - NOTED BY * AND STRIKE-THROUGH

                  (a) At any time prior to the second anniversary of this
Agreement, as liquidated damages for HMRI's inability to supply a Product under
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
purchase of Product and the prices set forth in * of the Contract Manufacturing
Agreement for the purchase of ANDA Product. All amounts owed by HMRI pursuant to
this Section 3.10(a) will be paid forty-five (45) days after the date of the
onset of such inability to supply and each forty-five (45) days thereafter
during the period of such inability to supply. Any rectification of the
inability to supply a Product or an ANDA Product shall be effective as of the
first day of the next calendar quarter; the parties shall jointly agree on the
amount of such credits remaining for the purchase of Product pursuant to Section
3.11 herein or ANDA Product pursuant to Section 2.12 of the Contract
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 Section 3.14. Rugby shall be

entitled to set-off amounts owed 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 at all times thereafter, the pricing for the Products
shall be as set forth in * of Exhibit A to this Agreement and in addition shall
include a manufacturing profit to HMRI of *% (except for sucralfate, which after
the * anniversary of this Agreement will be supplied at cost and will have the
profit split 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 SUCRALFATE. Beginning January
1, 1999 and continuing in perpetuity, Rugby shall make payments to HMRI equal to
*% of the Net Profit of sucralfate, based upon the quarterly periods ended March
31, June 30, September 30 and December 31. After January 1, 1999 through the
second anniversary of this Agreement, the profit split for sucralfate 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 sucralfate 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 sucralfate, multiplied by the following fraction, the
numerator of which is equal to the number of units of sucralfate 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 sucralfate) 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
sucralfate, 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 sucralfate 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 sucralfate, 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 sucralfate, 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 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 and excise, sales or use, value added or other taxes or levies
(collectively, "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 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.

                              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, 2001,
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 two years' prior written notification to the other
that this Agreement will terminate, which notification shall specify the date
upon which this Agreement shall terminate (which in any event shall not be prior
to December 31, 2001). If HMRI so notifies Rugby that this Agreement will
terminate, HMRI will, as soon as reasonably practicable during the two-year
notice period, 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.2 EARLY TERMINATION.

                  (a) Either Rugby or HMRI, as the case may be, may terminate
this 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

                  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 )

                  V.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

                  V.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, which will certify that the Product was manufactured in accordance with
the 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 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
materials, packaging materials, their source, analytical test procedures or
critical manufacturing conditions or manufacturing equipment used in the
manufacture of Product.

                  V.4 ACCESS TO FACILITIES.

                    (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 5.4(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 5.4(b), HMRI
shall have no obligation or be deemed to have an obligation to inspect the
warehouse and distribution facilities of Rugby.

                  V.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.

                  V.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, 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
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.

                                   ARTICLE VII
                                   WARRANTIES

applicable thereto.

                  VII.2 CONFORMITY WITH SPECIFICATIONS. HMRI warrants that each
Product manufactured by HMRI and sold to Rugby pursuant to this Agreement will
meet the Specifications for such Product in effect at the time title to such
Product passes from HMRI to Rugby pursuant to Section 3.6 herein. HMRI reserves
the right to amend such Specifications from time to time at the sole discretion
of HMRI, provided that Rugby is provided with written notice within a
commercially reasonable period of time in advance in order to effect any
necessary marketing or other changes and, provided further that such changes do
not cause the product delivered to Rugby to cease to be the equivalent of the
applicable Product then sold by HMRI.

                  VII.3 COMPLIANCE WITH THE FEDERAL FOOD, DRUG AND COSMETIC ACT.
HMRI warrants that all Product delivered to Rugby pursuant to this Agreement

                  VII.5 EXCLUSION OF OTHER WARRANTIES. EXCEPT WHERE OTHERWISE
SET FORTH IN THIS AGREEMENT, SECTIONS 7.1, 7.2, 7.3 AND 7.4 ARE IN LIEU OF ALL
CONDITIONS, WARRANTIES AND STATEMENTS IN RESPECT OF PRODUCT AND IN RESPECT OF
THE MANUFACTURING SERVICES PROVIDED HEREUNDER, WHETHER EXPRESSED OR IMPLIED BY
STATUTE, CUSTOM OF THE TRADE OR OTHERWISE (INCLUDING BUT WITHOUT LIMITATION ANY
SUCH CONDITION, WARRANTY OR STATEMENT RELATING TO THE DESCRIPTION OR QUALITY OF

UNDER ANY CONDITIONS) AND ANY SUCH CONDITION, WARRANTY OR STATEMENT IS HEREBY
EXCLUDED. EXCEPT AS PROVIDED IN ARTICLE 9 HEREIN, REPLACEMENT OF ANY
NONCONFORMING PRODUCT AND REASONABLE DOCUMENTED OUT OF POCKET EXPENSES SHALL BE
RUGBY'S SOLE REMEDY FOR BREACH OF ANY EXPRESS WARRANTY CONTAINED IN THIS ARTICLE
VII. In no event shall HMRI or Rugby be liable under or with respect to this

                                  ARTICLE VIII
                  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

HMRI Know-How on a need to know basis and shall be 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

                  disclosed to the receiving party or its Affiliates or

                  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

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 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.

                  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

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;

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

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 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.

                  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.

                               DISPUTE RESOLUTION

                  X.1 MEDIATION COMMITTEE. The Chief Executive Officers or
Presidents of the parties shall constitute the mediation committee (the
"Mediation Committee"). In the event any dispute or controversy arises under,
out of, in connection with or in relation to this Agreement or any amendments or
proposed amendment thereto or any breach thereof the parties agree that, before
any party initiates arbitration proceedings pursuant to Section 10.6, it shall
give the other party notice and shall demand that the members of the Mediation
Committee attempt to resolve the matter amicably. If the Mediation Committee is
unable to resolve a matter within ten (10) days of submission of the matter to
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
resolve a dispute, unless a mutually acceptable extension is agreed upon by the
Mediation Committee, either side shall have the right, but not the obligation,
to initiate arbitration proceedings respecting the matter under review, in
accordance with Section 10.6 herein.

                  X.2 NON-ARBITRABLE ISSUES. The parties acknowledge that
matters 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.

                  X.3 SCOPE OF ARBITRATION. The parties agree that all disputes
and controversies except those set forth in Section 10.2 herein arising under
this Agreement shall be resolved by arbitration in accordance with the
provisions of this Article 10; provided, however, that during the period of
arbitration on any dispute the parties shall continue to fulfill their
obligations as set forth in this Agreement.

                  X.4 ARBITRATION PANEL. The arbitration shall be held before a
panel of three (3) persons (the "Arbitration Panel").

                  X.4.1 Selection. Within fifteen (15) days of the appointment
of the two initial arbitrators, the two arbitrators so appointed shall appoint
the third arbitrator, who shall be an attorney and shall act as chair of the
Arbitration Panel.

                  X.4.2 Qualifications. The two arbitrators selected by the
parties hereto shall have experience in the pharmaceutical and/or biotechnology
industry. None of the arbitrators shall have been employed or be retained by or
otherwise related to HMRI or Rugby.

                  X.4.3 Failure to Name. If a party fails to name its arbitrator
within thirty (30) days of the receipt of the Notice of Arbitration (as defined
herein), then the arbitrator already named shall immediately select the second
arbitrator. The two arbitrators so appointed shall appoint the third arbitrator,
who shall be an attorney and shall act as chair of the Arbitration Panel.

                  X.4.4 Right to Select Replacement. In the event that an
arbitrator refuses or is otherwise unable to serve as such, the party or the
other arbitrator(s) as the case may be, who selected such arbitrator shall have
the right to select his/her replacement. Such replacement shall be selected
within fifteen (15) days of the refusal or inability by such arbitrator to
serve.

         X.5 DESIGNATION OF RULES, SITUS, GOVERNING LAW.

                  X.5.1 Designation of Rules. The parties agree that the
arbitrators shall apply the Federal Rules of Evidence as they are applied in
cases tried to a court sitting without a jury; unless the parties otherwise
agree in writing, the opinions of expert witnesses shall not be admissible. The
parties agree that discovery proceedings shall be limited to: (i) the dispute;
(ii) depositions of those persons having direct knowledge of the dispute; and
(iii) submission of all documents which relate to the dispute.

                  X.5.2 Situs. The arbitration hearing shall be held in New

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 10.1 herein.

                  X.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
10.4.2.

                  X.6.3 Response. Within thirty (30) days after receipt of the
Notice of Arbitration, the Respondent shall send the Claimant a written Response

                          CONFIDENTIAL TREATMENT - NOTED BY * AND STRIKE-THROUGH

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 10.4.2. 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.

                  X.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.

                  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
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.

                  X.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.

                  X.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.

(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.

                  X.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.

                           X.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.

                           X.6.11 Confidentiality. All arbitration proceedings
hereunder shall be conducted on a confidential basis and shall be subject to the
provisions of Article 8 (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.

                           X.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.

                  X.7 AUTHORITY OF ARBITRATORS.

                           X.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.

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

                  X.8 AWARDS.

                           X.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.

                           X.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.

                           (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

and between Rugby-Darby Group Companies, Inc. and Blue Ridge Laboratories, Inc.
relating to the manufacture of sucralfate tablets

and (ii) that certain Agreement dated as of November 21, 1991 by and between
Rugby-Darby Group Companies, Inc. and Blue Ridge Laboratories, Inc. relating to
diltiazem tablets. 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.

                  XI.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.

                  XI.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 under this Agreement. 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 11.4 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.

                  XI.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.

                  XI.6 ATTACHMENTS. All Exhibits referenced herein are hereby
made a part of this Agreement.

                  XI.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.

                  XI.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.

                  XI.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.

                  XI.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.

                  XI.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

as of August 25, 1997, as amended, by and among HMRI, Marisub, Inc. and Watson
Pharmaceuticals, Inc. (the "Stock Purchase Agreement"), for purposes of Article

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.

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 thereto are divided * between HMRI
and Rugby through December 31, *, and are at 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 in such package sizes shall be deemed to
be a "Product" pursuant to the terms of 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 two (2) years 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, 2000; provided,
further, that ranitidine, 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 four (4) consecutive short-term forecasts (under Section 3.5(b) hereof) with
respect to the first three (3) months of each such forecast.

                  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 one year's supply of
such Products, which supply is based upon the amount of Product purchased by
Rugby or its Subsidiaries over the previous twelve (12) months. 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 * ANDAs during the time that such qualification is pending. Rugby will
provide HMRI reasonable notification of its intent to qualify a second
manufacturing site for a Product for which technical consultation is requested
pursuant to this Section 2.4(b). Rugby will be responsible for all of HMRI's
reasonable out-of-pocket costs in connection with such technical consultation,
which expenses will be reimbursed by Rugby within thirty (30) days after
completion of such qualification.

                  II.5 LABELING AND PACKAGING. Rugby shall be responsible for
all costs of developing, packaging and labeling for the Product, and shall
provide HMRI all art work and pharmacological information, usage instructions
and warnings to be applied to each Product, which shall be consistent with the
FDA approved labeling for the Products. Rugby shall provide such information
pursuant to this Section 2.5 to HMRI a sufficient period of time in advance of
delivery requirements for the Products set forth in this Agreement.

                  II.6 FORECASTS.

                  (a) Long-Range Forecasts. Upon execution of this Agreement and
by October 1 of each year thereafter, Rugby shall provide HMRI with a forecast
of the quantities of each Product, by package size (SKU) and finished dosage
form, that Rugby intends to order during the three (3) year period commencing
with the following calendar year. The parties acknowledge that such forecasts
shall represent reasonable best faith estimates, not purchase commitments.

                  (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 calendar quarter, 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 twelve (12) month period commencing with
that calendar quarter, stipulating periodic delivery requirements. The first
three months 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 quarters as
follows:

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, provided that such Product meets the Specifications. In
no event shall the use of any form of order acknowledgment, purchase order,
shipping document, 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, which forecast is attached hereto as Exhibit C, will be binding

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
that the Product in question fails to meet the Specifications, HMRI shall
replace such Product at no additional cost to Rugby within ten (10) business
days after receipt of such results. In the event the test results indicate that

of shortage in quantity of any shipment of Product, and except as otherwise
provided in Section 8.2(a) herein, Sections 2.9(b) and (c), in the case of

provided in Section 6.4 Stock Purchase Agreement), based upon the quarterly
periods ended March 31, June 30, September 30 and December 31, in perpetuity.
Prior to the second year anniversary of this Agreement, the profit split for
ranitidine shall be calculated as if purchased at the cost set forth in *
Exhibit A to this Agreement. 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 ranitidine, multiplied by the following
fraction, the numerator of which is equal to the number of units of ranitidine
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
ranitidine) or service included in such bundled sale multiplied by the
respective standard invoice unit price thereof.

                  II.14 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
ranitidine, 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 ranitidine are being made, and
for one year thereafter) to examine the relevant books and records of the other
party relating to the manufacturing costs of Products, and sale of ranitidine,
as the case may be, during normal business hours and upon reasonable advance
written notice to verify the correctness of the calculations of the
manufacturing costs of the Products, or the profit split of ranitidine, 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 2.13 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 2.13 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 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

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.

                  II.15 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 2.11 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 2.12
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 to Rugby determined
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.

                  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.

                  II.16 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

shall not recommend or knowingly sell the Products for any uses except as
described in the FDA approved Product labeling.

                  II.17 TAXES. Rugby shall reimburse HMRI for all tariffs,
duties and excise, sales or use, value added or other taxes or levies
(collectively, "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

                           (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

                    (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.

                  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.

clear of all liens, encumbrances, security interests and other encumbrances.

                  VI.6 EXCLUSION OF OTHER WARRANTIES. EXCEPT WHERE OTHERWISE SET
FORTH IN THIS AGREEMENT, SECTIONS 6.1, 6.2, 6.3, 6.4 AND 6.5 ARE IN LIEU OF ALL
CONDITIONS, WARRANTIES AND STATEMENTS IN RESPECT OF PRODUCT AND IN RESPECT OF
THE MANUFACTURING SERVICES PROVIDED HEREUNDER, WHETHER EXPRESSED OR IMPLIED BY

this Agreement.

                  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
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 or
Rugby Know-How, as the case may be, secret and confidential and to respect the
other'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 or Rugby Know-How, as the case may be, to any third party.

                  (b) Each party shall procure that only its respective
employees or employees of its Affiliates or consultants and contractors shall

principals pursuant to Section 7.1(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
finances of the other or of any Affiliates, suppliers, agents, distributors,
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
7.1 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;

                  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

                  statutory, regulatory or similar legislative requirement or

                  VII.2 TERMS OF THIS AGREEMENT. Rugby and HMRI each agree not
to 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 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.

                  VII.4 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 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:

                          CONFIDENTIAL TREATMENT - NOTED BY * AND STRIKE-THROUGH

                  (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;

                  (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.

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

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

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.

                               DISPUTE RESOLUTION

proposed amendment thereto or any breach thereof the parties agree that, before
any party initiates arbitration proceedings pursuant to Section 9.6, it shall
give the other party notice and shall demand that the members of the Mediation
Committee attempt to resolve the matter amicably. If the Mediation Committee is
unable to resolve a matter within ten (10) days of submission of the matter to
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

mutually acceptable extension is agreed upon by the Mediation Committee, either
side shall have the right, but not the obligation, to initiate arbitration
proceedings respecting the matter under review, in accordance with Section 9.6
herein.

                  IX.2 NON-ARBITRABLE ISSUES. The parties acknowledge that
matters relating to product recalls as set forth in Article 5 herein, Disputes
as set forth in Section 2.14 and the matters set forth in Section 7.3 shall not
be submitted to arbitration pursuant to Section 9.3 hereof but instead shall be
resolved in accordance with Section 5.2, 2.14 and 7.3 herein respectively.

                  IX.3 SCOPE OF ARBITRATION. The parties agree that all disputes
and controversies except those set forth in Section 9.2 herein arising under

                  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.

                           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.

                           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.

                           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.

                  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.

                  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
