OVERVIEW
 
  Watson Pharmaceuticals, Inc., incorporated in 1985, is engaged in the
development, production, marketing and distribution of branded and off-patent
pharmaceutical products. The Company's products include therapeutic and
preventive agents generally sold by prescription or over-the-counter (OTC) for
the treatment of human diseases and disorders.
 
Branded Pharmaceutical Products
 
  New pharmaceutical products are often patented and, as a result, generally
are offered by a single provider when first introduced to the market. In
addition to patented products, certain trademarked off-patent products which
are promoted directly to healthcare professionals are treated by Watson as
branded pharmaceutical products.
 
 
                                       2
<PAGE>
 
  The Company's branded pharmaceutical business operates primarily in the
following specialty areas: Dermatology, Women's Health, Neurology/Psychiatry
and Primary Care. Watson has strategically focused on these markets due to
their anticipated growth opportunities. The Company believes that the nature
of these markets and the identifiable base of physician prescribers provide it
with the opportunity to achieve significant market penetration through its
specialized sales forces. The Company believes its branded pharmaceutical
products tend to generate more stable earnings over a longer period, in large
part through higher margins. The Company intends to continue to expand its
branded product portfolio through internal product development and acquisition
or may also choose to enter into collaborative or licensing agreements with
third parties at various stages of product development.
 
Off-Patent Pharmaceutical Products
 
  When the relevant patents no longer protect a branded product (either due to
the patent's expiration or otherwise), opportunities exist for third parties
to introduce generic counterparts to the branded product. Such generic or off-
patent pharmaceutical products are therapeutically equivalent to their brand-
name counterparts and are generally sold at prices significantly less than the
branded product. Accordingly, off-patent pharmaceuticals provide a safe,
effective and cost-efficient alternative to users of branded products.
 
  The Company is recognized as a leader in the development, manufacture and
sale of off-patent pharmaceutical products. With respect to off-patent
products, the Company's strategy is to enter markets where it enjoys
competitive advantages. In this regard, the Company targets for development
drugs that are difficult to formulate or manufacture, or that will complement
its existing portfolio, or that will otherwise assist it in making its product
line more complete.
 
Revenues From Pharmaceutical Sales
 
  Company revenues for the last three fiscal years were derived as follows:

(1) Following Watson's acquisition of the U.S. rights to Dilacor XR(R) from
    Rhone-Poulenc Rorer Pharmaceuticals, Inc. ("RPR") as of June 30, 1997, no
    further royalty income was earned.
 
SUMMARY OF RECENT TRANSACTIONS
 
  Several acquisitions have contributed to the Company's growth over the past
year. In February 1998, the Company acquired from Hoechst Marion Roussel, Inc.
("HMR") The Rugby Group, Inc. ("Rugby"), a developer and marketer of off-
patent pharmaceutical products, for approximately $67.5 million in cash
(exclusive of certain contingent payments). The Company also entered into a
supply agreement with HMR under which Watson currently purchases certain off-
patent products.
 
  In November 1998, the Company acquired three branded oral contraceptive
products from G. D. Searle & Co. ("Searle"), Norinyl(R), Brevicon(R), and Tri-
Norinyl(R), for $120.0 million cash. The Company and Searle also entered into
a supply agreement under which the Company is currently purchasing these
products. Under the supply agreement with Searle, the Company has the right to
purchase these products from Searle for three years; the first two years in
finished packaged form and the third year in bulk tablet form.
 
                                       3
<PAGE>
 
  In January 1999, Watson acquired TheraTech, Inc. ("TheraTech"), a leading
drug-delivery company, in a share for share exchange for approximately 5.8
million Watson common shares. TheraTech develops advanced, controlled-release
and other drug-delivery products which administer drugs through the skin, by
oral delivery to
the gastrointestinal tract, through tissues in the oral cavity, through
absorption in the lungs and by other means. TheraTech believes its products
provide advantages over existing controlled-released drug-delivery products
and conventional oral, injectable, inhalation and continuous infusion methods
by increasing efficacy, safety, bioavailability and/or patient compliance and
comfort. TheraTech focuses its research and development efforts on the design
and development of improved delivery systems for off-patent and proprietary
drugs.
 
  The U.S. Food and Drug Administration ("FDA") has approved for marketing
three of TheraTech's developed products. Two of these products, the
Androderm(R) two and one half milligram (2.5 mg) testosterone transdermal
system for men and the Alora(R) estradiol transdermal system for women,
received marketing approval within one year of their respective initial
submissions.
 
  As of March 15, 1999, TheraTech had 208 full-time and 9 part-time employees.
Of the total number, 92 employees were engaged in research and development
activities, 59 employees were in manufacturing, and 66 employees were in
administrative capacities. TheraTech's management team consists of
pharmaceutical industry specialists, including individuals with experience
ranging from project conception and design to regulatory approval process and
commercial production.
 
  TheraTech's principal facilities are located in Salt Lake City, Utah. These
facilities include approximately 76,000 square feet of research and
development, pilot manufacturing and packaging, and administrative space under
one lease. The lease expires in May 1999 and has two, one-year renewal
options. TheraTech has also entered into a 40-year lease, with an option to
renew for an additional ten years, on approximately seven acres of land
located in the University of Utah Research Park for its commercial
manufacturing facility. TheraTech also maintains approximately 3,000 square
feet of leased space for business development and related purposes in Tokyo,
Japan.
 
  The Rugby, Searle and TheraTech transactions are more fully described in
Note 2 to the consolidated financial statements.
 
PRODUCTS
 
Branded pharmaceutical products
 
  The Company markets its branded products to physicians through its four
principal sales groups: Dermatology, Women's Health, Neurology/Psychiatry and
Primary Care. As of March 15, 1999, the Company marketed the following branded
products:
 
 Dermatology
 
  Watson markets several products for the prevention and treatment of skin
diseases. These products include 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), for the treatment of genital warts; and Cinobac(R) (cinoxacin),
for the treatment of urinary tract infections.
 
 Women's Health
 
  The Company markets a variety of oral contraceptive products. These products
include Zovia(TM) (ethynodiol diacetate & ethinyl estradiol), Levora(R)
(levonorgestrel), Nor QD(R) (norethindrone), Trivora(R) (levonorgestrel and
ethinyl estradiol tablets, USP--Triphasic Regimen), Norinyl(R) (norethindrone
and ethinyl estradiol), Brevicon(R) (norethindrone and ethinyl estradiol), and
Tri-Norinyl(R) (norethindrone and ethinyl estradiol).
 
                                       4
<PAGE>
 
 Neurology/Psychiatry
 
  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, for the treatment of Parkinson's disease.
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. In 1997, sales of Dilacor XR(R) accounted for approximately 19% of
total revenues following Watson's June 1997 purchase of Dilacor XR(R). In
1998, sales of Dilacor XR(R) accounted for approximately 15% of total
revenues. The Company expects that the significance of Dilacor XR(R) as a
percentage of total revenues will continue to decline as a result of new
product introductions and acquisitions, increased revenues from existing
products and increased competition; and that Dilacor XR(R) will not represent
a significant portion of Watson's revenues in 1999.
 
Off-patent pharmaceutical products
 
  Watson manufactures and markets more than 85 off-patent prescription
products in capsule or tablet forms in approximately 166 dosage strengths. The
Company markets its off-patent products to drug wholesalers, distributors and
retailers, including chain drug stores, hospitals, clinics, governmental
agencies, and managed healthcare providers such as health maintenance
organizations and other institutions.
 
  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 (a) acquisitions by the Company in 1997 and 1998, (b)
modification of certain federal and state laws to permit or mandate
substitution of off-patent drugs by pharmacists, (c) the enactment of
abbreviated procedures for obtaining FDA approval to manufacture off-patent
prescription drugs, (d) changes in government and third-party payor
reimbursement policies to encourage cost containment by health care providers
and consumers, (e) increased acceptance of off-patent drugs by physicians,
pharmacists and consumers, and (f) an increasing number of products which have
lost patent protection.
 
  During 1998, the hydrocodone bitartrate & acetaminophen off-patent product
group accounted for approximately 13% of total revenues. In 1997, the
hydrocodone bitartrate & acetaminophen off-patent product group accounted for
approximately 21% of total revenues and in 1996 this same product group
accounted for 29% of total revenues.
 
JOINT VENTURES
 
  Watson has made substantial investments in pharmaceutical joint ventures and
may 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, although Watson
does market Somerset's Eldepryl(R). Further, there is no assurance that such
joint ventures will be profitable, or if profitable currently, will continue
to be profitable.
 
  The Company owns a 50% interest in Somerset, a joint venture with Mylan
Laboratories, Inc. Currently, Somerset's only marketed product is Eldepryl(R).
Somerset, however, is actively involved in research projects regarding
additional indications for Eldepryl(R) and other chemical compounds. In
addition, the Company owns a 50% interest in ANCIRC, a joint venture with
Andrx Corporation ("Andrx"), that is developing off-patent pharmaceutical
products utilizing Andrx's controlled-release technology. In 1998, ANCIRC
received one abbreviated new drug application ("ANDA") product approval from
the FDA and as of March 15, 1999, ANCIRC had one ANDA under review with the
FDA. At December 31, 1998, Watson owned approximately 17.7% of the outstanding
common stock of Andrx. The Company also has a warrant to purchase 337,079
shares of Andrx common stock (which represented approximately 2.2% of the
outstanding shares of Andrx common stock at December 31, 1998) at an exercise
price of $8.90 per share.
 
                                       5
<PAGE>
 
PRODUCT DEVELOPMENT
 
  The Company devotes significant resources to the research and development of
branded and off-patent products. During the three years ended December 31,
1998, the Company incurred research and development expenditures of $30.8
million, $18.1 million and $22.9 million, respectively. There can be no
assurance that any of the products currently in development will receive the
required regulatory approvals from the FDA or be commercially successful if
ultimately approved.
 
  Watson's research and development strategy focuses on the following product
development areas: (a) expansion of its existing oral immediate-release
products with respect to additional dosage strengths, (b) off-patent drugs
that are technically difficult to develop or make because of unusual factors
that affect their shelf life or bioequivalence or are sold in smaller
specialized markets, (c) the development of sustained-release technologies and
the application of these technologies to existing products, (d) the
application of proprietary drug-delivery technology for new product
development in specialty areas, and (e) medium-to-late stage new drug
opportunities.
 
  Watson maintains research and development facilities in Corona, California,
Miami, Florida and Cincinnati, Ohio.
 
Branded product development
 
  Watson continues to develop certain branded products, some of which utilize
novel drug-delivery systems. Such branded products generally 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. Watson's proprietary product
development continues to emphasize mid-to-late-stage new drug opportunities
that can quickly be brought to market.
 
  The Company is focusing its proprietary drug development efforts in the
three specialty areas where Watson has existing sales and marketing presence,
namely Women's Health, Neurology/Psychiatry and Dermatology. Products
currently in development include: a hormone replacement therapy, a dermatology
product, a central nervous system product, and an analgesic product.
 
  In recent years, Somerset has increased its research and development
spending in order to (a) develop additional indications for selegiline (the
parent compound of Eldepryl(R)), using a transdermal delivery system and (b)
develop and evaluate different therapeutic areas using selegiline and other
compounds. Clinical studies using the selegiline transdermal system (STS) in
major depression were completed in 1998.
 
Off-patent product development
 
  Watson intends to continue to concentrate its development activities in
areas that offer significant opportunity and that allow Watson to develop
competitive advantages. For instance, the Company has focused its development
efforts on technically difficult-to-formulate products, or products that
require advanced manufacturing technology. By so doing, the Company seeks to
secure a competitive advantage and increased profitability with these
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 acquisition of Royce Laboratories, Inc. ("Royce") in 1997 and
Rugby in 1998 has increased its resources in the area of off-patent product
development. The Company presently has submissions for approval pending before
the FDA representing 17 separate products of varying dosage strengths. During
1998 and through March 15, 1999, Watson received 10 off-patent product
approvals from the FDA.
 
                                       6
<PAGE>
 
  As of March 15, 1999, the Company believed that it received the first ANDA
approval for approximately 40 products and/or dosage strengths. Also as of
March 15, 1999, the Company believed that it received the sole ANDA approval
for approximately 13 products and/or dosage strengths.
 
  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 exceeding $50 million.
 
SALES AND MARKETING
 
  The Company sells its pharmaceutical products to drug wholesalers, retailers
and distributors, including large chain drug stores, hospitals, clinics,
government agencies and managed healthcare providers such as health
maintenance organizations and other institutions.
 
Branded products
 
  The Company markets its branded products through its specialty sales groups:
Dermatology, Women's Health, Neurology/Psychiatry 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 1998, the Company continued to develop 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 group
had grown to include more than 350 sales representatives by the end of 1998.
 
Off-patent products
 
  Customer service activities are an integral part of the Company's sales and
marketing operations. The Company endeavors to maintain adequate inventories,
make timely delivery of its products and provide technical and other service
support to its customers. During 1998, Rugby's telemarketing organization and
other sales and marketing personnel were integrated into the Company's
existing infrastructure, enhancing its sales and marketing efforts in the off-
patent product area.
 
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. 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 off-patent 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 1998, two
customers accounted for 17% and 12%, individually, of the Company's product
sales. In 1997, these same two customers accounted for 12% and 11%,
individually, of the Company's product sales. In 1996, one customer accounted
for 10% of product sales.
 
Competition
 
  The pharmaceutical industry is highly competitive, and in many cases, highly
regulated. Watson's competitors vary depending upon categories, and within
each product category, upon dosage strengths and drug-delivery systems. Such
competitors include the major brand name and off-patent manufacturers of
 
                                       7
<PAGE>
 
pharmaceuticals, especially those doing business in the United States. Many
competitors have been in business for a longer period of time than Watson,
have a greater number of products on the market and have greater financial and
other resources. Watson competes principally through its targeted product
development strategies. In addition to product development, other competitive
factors in the pharmaceutical industry include product quality and price,
reputation and access to technical information.
 
  Newly introduced off-patent products with limited or no off-patent
competition are typically sold at higher selling prices, often resulting in
increased gross profit margins. As competition from other manufacturers
intensifies selling prices typically decline. Consequently, the maintenance of
profitable operations depends, in part, on the Company's ability to maintain
efficient production capabilities and to develop and introduce new products in
a timely and cost-effective manner.
 
  Revenues and gross profit derived from the sales of off-patent
pharmaceutical products tend to follow a pattern based on certain regulatory
and competitive factors. 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 (a) the number of
competitors in that product's market and (b) the timing of that product's
regulatory approval, in relation to competing approvals. 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 by establishing, acquiring or forming licensing or
business arrangements with other off-patent pharmaceutical companies.
 
  With respect to its branded products, the competitive environment requires
an intensive search for technological innovations and the Company's ability to
market the products effectively, including its ability to communicate the
effectiveness, safety and value of the Company's branded products to
healthcare professionals in private practice, group practices and managed care
organizations.
 
SUPPLIERS AND MATERIALS
 
  The principal components used in the Company's products are active and
inactive pharmaceutical ingredients and packaging materials. The Company
maintains its own manufacturing capabilities but also contracts with third
parties for the manufacture of a number of its finished products. Certain
third-party components and finished products (including certain products that
have historically accounted for a significant portion of Watson's revenues)
are currently available only from sole or limited suppliers. The FDA (and in
some cases, other regulatory agencies) must approve suppliers for the
Company's products. The Company's third-party suppliers 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 suppliers to comply with such requirements or similar standards
imposed by foreign regulators. 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. If any of the components or finished
products were no longer available from an existing approved source, a
qualified alternative would have to be located. This process could delay the
manufacture and sale of such products. In addition, there can be no assurance
that the Company will continue to be able to obtain such items on a timely
basis or at commercially reasonable prices. Any extended inability to timely
obtain components or finished products, or any significant price increases
that cannot be passed on to customers, could have a material adverse effect on
the Company. From time to time, certain outside suppliers have experienced
regulatory difficulties that have inhibited their ability to deliver products
to the Company. To the extent such regulatory difficulties cannot be resolved
within a reasonable time, the resulting delay could have a material adverse
effect on the Company.

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 and has numerous issued and pending United
States patents. The Company also seeks patent protection in major foreign
pharmaceutical markets, and has a number of foreign patents that are issued
and pending.
 
  There can be no assurance that Watson's patents or those of its competitors
will be held valid by a court of competent jurisdiction. There also 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. In addition, any time the
Company files an ANDA in which it certifies that its product is not infringing
or that the patent covering the NDA patent is invalid, the patent holder may
file suit against the Company for patent infringement. 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 ultimately 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, record keeping, 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, civil
sanctions and criminal prosecution. The FDA also has the authority to revoke
previously granted drug approvals. From time to time, the FDA issues notices
and warning letters to pharmaceutical manufacturers that request or require
the manufacturer to modify certain activities with which the FDA finds fault.
To facilitate compliance, the Company from time to time may institute
voluntary compliance programs.
 
  The FDA's cGMP standards have become more complex in recent years. 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
 
                                       9
<PAGE>
 
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.
 
  The Hatch-Waxman Act of 1984 extended the established ANDA application
procedure for obtaining FDA approval of generic forms of brand-name drugs,
which were originally marketed before 1962 or whose market exclusivity has
expired. Upon filing an ANDA application with the FDA, the Company must make
one of five certifications with respect to patents. If the Company certifies
that its product is not infringing or that the NDA patent is invalid, then a
NDA patent holder can file suit against the ANDA applicant. Once a suit is
filed, the FDA is prohibited from approving the ANDA for thirty months or
until the suit is litigated. The Hatch-Waxman 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 of the Hatch-Waxman Act 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. In addition, 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 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 NDA or 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 is currently
11% of the average wholesale price for sales of Medicaid-reimbursed products
marketed under ANDAs. For sales of medicaid-reimbursed products marketed under
NDAs, manufacturers are required to rebate the greater of approximately 15.1%
of the average wholesale price or, the difference between the average net
sales price and the lowest net sales price during a specified period. 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
 
                                      10
<PAGE>
 
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.
 
  It is impossible for the Company to predict the extent to which its
operations will be affected under regulations discussed above or any new
regulations that may be adopted by regulatory agencies.
 
SEASONALITY
 
  The Company's business, taken as a whole, is not materially affected by
seasonal factors.
 
PERSONNEL
 
  As of December 31, 1998, the Company had 1,510 full-time employees. Of the
Company's employees, 164 are engaged in research and development, 479 in
manufacturing, 214 in quality assurance and quality control, 498 in sales and
marketing, and 155 in administration. Employees are not represented by unions
and the Company believes its relations with its employees are good.
 
BUSINESS--RISK FACTORS
 
  In addition to the other information in this Annual Report on Form 10-K, you
should carefully consider the following risk factors in evaluating Watson's
business.
 
 Risks Associated with Investing in Watson Common Stock
 
Watson is dependent on product development and commercialization for continued
growth and development.
 
  Watson's future results of operations will depend to a significant extent
upon its ability to successfully commercialize new proprietary and off-patent
pharmaceutical products in a timely manner. As a result, new products must be
continually developed, tested and manufactured and, in addition, must meet
regulatory standards and receive requisite regulatory approvals. Products
currently in development by the Company may or may not receive the regulatory
approvals necessary for marketing by Watson or other third-party partners.
Furthermore, the development and commercialization process is time-consuming
and costly, and we cannot assure you that any of Watson's products, if and
when developed and approved, can be successfully commercialized. Risk
particularly exists with respect to the development of proprietary products,
because of the uncertainties and higher costs associated with research and
development of such products and the unproven market acceptability of such
products. Delays or unanticipated costs in any part of the process or the
inability of Watson to obtain regulatory approval for its products, including
failure to maintain its manufacturing facilities in compliance with all
applicable regulatory requirements, could adversely affect Watson's operating
results.
 
The effect of future transactions on Watson's business or stock price is
uncertain.
 
  Watson regularly reviews potential transactions related to technologies,
products or product rights and businesses complementary to its business. Such
transactions could include mergers, acquisitions, strategic alliances,
licensing agreements or co-promotion agreements. In the future, Watson may
choose to enter into such transactions at any time. The impact of transactions
on the market price of a company's stock is often uncertain, but may cause
substantial fluctuations to the market price. Consequently, you should be
aware that any announcement of any such transaction could have a material
adverse effect upon the market price of Watson's common stock. Moreover,
depending upon the nature of any transaction, Watson may experience a charge
to earnings, which could be material, and could possibly have an adverse
impact upon the market price of Watson common stock. In connection with the
TheraTech merger, Watson expects to record merger-related expenses of
 
                                      11
<PAGE>
 
approximately $20 million in the first quarter of 1999. In addition, any such
transaction could be disruptive to the management of Watson, and any such
disruption could also have a material adverse effect on its business or
financial condition.
 
Watson's stock price has experienced substantial volatility. Watson has not
paid and does not intend to pay dividends.
 
  The market prices for securities of companies engaged primarily in the
pharmaceutical industry have been volatile, and the market price of Watson
common stock has been and may continue to be volatile. For example, the market
price of Watson common stock fluctuated during the past twelve months between
$30.50 per share and $63.00 per share and may continue to fluctuate. Generally
market price fluctuations in a company's stock may be due to acquisition or
other material public announcements, along with a variety of additional
factors including, without limitation:
 
  (a) new product introductions,
 
  (b) the purchasing practices of the Company's customers,
 
  (c) changes in the degree of competition for a company's products,
 
  (d) the announcement of technological innovations or new commercial
      products by a company or its competitors,
 
  (e) governmental regulation,
 
  (f) regulatory approvals or regulatory issues,
 
  (g) developments relating to patents or proprietary rights,
 
  (h) publicity regarding actual or potential clinical results with respect
      to products under development by a company or others and
 
  (i) political developments or proposed legislation in the pharmaceutical or
      healthcare industry.
 
  Any of these factors, among others, could have a significant impact on the
market price of Watson's common stock.
 
  The Company has not paid any cash dividends since inception, although
certain of its wholly-owned subsidiaries may have paid dividends prior to a
combination with Watson. Watson does not anticipate paying cash dividends in
the foreseeable future.
 
The Company's issued common stock could experience dilution as a result of
future transactions.
 
  In April 1998, Watson filed a registration statement with the SEC which
allows Watson to raise up to $300 million from offerings of senior or
subordinated debt securities, common stock, preferred stock or a combination
thereof, at such times and in such amounts as Watson deems appropriate. To
date, Watson has issued $150 million in senior unsecured notes pursuant to
such registration statement. In addition, (a) Watson may engage in future
transactions, including the acquisition of technologies, products, product
rights and businesses, which could involve the issuance of its securities and
(b) Watson has commitments pursuant to existing option plans and free-standing
options and warrants which are likely to result in the issuance of additional
shares of Watson common stock. The issuance of any securities for these or
other reasons could result in dilution of existing shareholders' equity
interest in Watson. In addition, the Watson Board of Directors has the
authority to issue, without vote or action of shareholders, shares of
preferred stock, in one or more series, and to fix the rights, preferences,
privileges and restrictions thereof. Any such series of preferred stock could
contain dividend rights, conversion rights, voting rights, terms of
redemption, redemption prices, liquidation preferences or other rights
superior to the rights of holders of Watson common stock. The Watson Board of
Directors has no present intention of issuing any such preferred series, but
reserves the right to do so in the future.

 Risks Associated with Investing in the Business of Watson
 
The pharmaceutical industry is extensively regulated by various government
agencies.
 
  All pharmaceutical manufacturers are subject to extensive, complex, costly
and evolving governmental regulations and restrictions administered by the
FDA, other federal and state agencies, and numerous governmental authorities
in other countries. Moreover, Watson and certain of its vendors are subject to
the periodic inspection of their facilities and operations and/or the testing
of their products by the FDA, the U.S. Drug Enforcement Agency ("DEA"), the
U.S. Environmental Protection Agency ("EPA") and similar state, local and
foreign regulatory authorities. Each of these organizations conducts periodic
inspections to confirm continued compliance with its regulations. In
connection with such an inspection by FDA of the Company's Corona, California
facility, the FDA issued to the Company a Warning Letter in January 1999. The
Warning Letter related to the Company's cGMP compliance in areas such as
documentation, training and laboratory controls. The Company has responded to
the FDA and has adopted certain improvements to its procedures. Watson intends
to implement certain additional corrective improvements and anticipates that
these activities will be substantially completed within the next few months.
The Company does not expect that expenditures for these improvements will be
material. Product production at Watson's Corona facility has not been
interrupted, and the Company expects that production will continue, while it
implements the improvements.
 
  Failure to comply with governmental regulations could result in fines,
unanticipated compliance expenditures, interruption of production and criminal
prosecution. Although Watson has instituted internal compliance programs, we
cannot assure you that such programs will meet regulatory agency standards and
that any lack of compliance will not have a material adverse effect on Watson.
 
  The process for obtaining governmental approval to manufacture and market
pharmaceutical products is rigorous, time-consuming and costly, and Watson
cannot predict the extent to which it may be affected by legislative and
regulatory developments. Watson is dependent on receiving FDA and other
governmental approvals prior to manufacturing, marketing and shipping its
products. Consequently, there is always the chance that the FDA or other
applicable agency will not approve products, or that the rate, timing and cost
of such approvals will adversely affect Watson's product introduction plans or
results of operations. The URAA, which became effective June 8, 1994,
lengthens the term of existing and future patents by changing the patent term
to the longer of 17 years from the date of patent grant or 20 years from the
date of patent application. These URAA changes could postpone approval
eligibility of some products.
 
Watson is dependent on key personnel for its continued growth and development.
 
  The success of Watson's present and future operations will depend, to a
great extent, upon the experience, abilities and continued services of certain
executive officers of Watson, including Allen Chao, Ph.D. The loss of the
services of any of these officers could have a material adverse effect on the
Company. Watson has entered into employment agreements with certain of its
executive officers, including Dr. Chao. Watson does not carry key-man life
insurance on any of its officers. Watson's success also will depend upon its
ability to attract and retain other highly qualified scientific, managerial,
sales and manufacturing personnel. However, there is a risk of departure of
employees due to certain factors, including factors relating to the
integration process following mergers. Competition for such personnel is
intense. In this respect, Watson competes with numerous pharmaceutical and
healthcare companies, as well as universities and nonprofit research
organizations. We cannot assure you that Watson will continue to attract and
retain qualified personnel.
 
Watson may not be able to obtain patent coverage or otherwise protect
proprietary technology.
 
  Watson's success with its proprietary products will depend in part on its
ability to obtain patent protection for its products. Watson has a number of
U.S. and foreign patents issued and pending. However, we cannot assure you
that Watson's patent applications will be approved, or if approved will be
upheld in a court of law. We also cannot assure you that such patents will
provide competitive advantages for their respective products or will not be
challenged or circumvented by competitors.
 
                                      13
<PAGE>
 
  Watson also relies on trade secrets and proprietary know-how which it seeks
to protect, in part, through confidentiality agreements with its partners,
customers, employees and consultants. It is possible that these agreements
will be breached or that they won't be enforceable in every instance, and that
Watson will not have adequate remedies for any such breach. It is also
possible that Watson's trade secrets will become known or independently
developed by competitors.
 
  Watson may be required or may desire to obtain licenses to patents and other
proprietary rights held by third parties to develop, manufacture and market
products. We cannot assure you that Watson will be able to obtain these
licenses on commercially reasonable terms, if at all, or that any licensed
patents or proprietary rights will be valid or enforceable. In addition,
intellectual property law is subject to change by the courts and other
governmental bodies. For example, a 1997 Supreme Court ruling could impact a
party's ability to enforce its patents and to defend against potential patent
infringement claims by third parties. Watson's ability to commercialize its
products will depend on it not infringing the valid patent rights of others.
Litigation concerning patents and proprietary technologies can be protracted
and expensive and brand companies are increasingly suing competitors as a way
of delaying the introduction of competitors' products. Any such litigation may
be costly and time consuming, and could result in a substantial delay in a new
product introduction, any of which could have a material adverse effect on
Watson's business, financial condition or results of operations.
 
Increased competition may cause reduced revenues and gross margins.
 
  Due to introduction of products from time to time that may compete with
Watson's products, Watson may continue to experience increased price
competition. Consequently, Watson may experience a reduction in future sales
or gross margin of such products which, absent additional offsetting revenues,
could have a material adverse effect on the financial condition and results of
operations of Watson.
 
Watson is dependent on certain suppliers that in some cases may be the only
source of finished products or raw materials.
 
  Some materials used in Watson's manufactured products, and some products
sold by Watson, are currently available only from sole or limited suppliers.
This includes products that have historically accounted for a significant
portion of Watson's revenues. In addition, sources for materials for Watson's
products must be approved by the FDA, the DEA and/or other governmental
agencies or bodies. For some products sold by Watson, only one or very few
suppliers have been approved for certain materials or products used in
Watson's products. Any interruption or delay in supply of materials or
products from sole or limited source suppliers, or delays in the applicable
governmental approval of new suppliers, or delay in approving Watson as the
manufacturer of such products, could have a material adverse effect on
Watson's business.
 
The Year 2000 issue may affect Watson's operations.
 
  Watson has assessed and continues to assess the potential impact of the
situation commonly referred to as the "Year 2000 Issue." The Year 2000 Issue
concerns the inability of information systems and computer software programs
to properly recognize and process date sensitive information relating to the
Year 2000 and beyond. Watson has several information system improvement
initiatives underway which management believes will adequately address the
Year 2000 Issue. However, if third party payors, suppliers, distributors,
transporters or joint venture partners do not adequately address their Year
2000 Issues or if Watson fails to successfully complete its Year 2000
initiative, it could be adversely affected in the future. For a discussion of
the Company's Year 2000 readiness see Item 7--Management's Discussion and
Analysis of Financial Condition and Results of Operations.
 
Watson may not receive anticipated income from its existing or future joint
ventures.
 
  A portion of Watson's net income is derived from joint ventures. In
addition, a substantial portion of Watson's efforts in developing controlled-
release technology prior to the TheraTech merger was primarily
 
                                      14
<PAGE>
 
conducted through joint ventures. These arrangements involve various partners.
Watson does not control the joint ventures or the commercial exploitation of
the licensed products, and we cannot assure you that such joint ventures will
be, or, if profitable, will continue to be profitable. Although restrictions
contained in certain of Watson's joint venture arrangements have not in the
past had a material adverse impact on Watson's marketing of its products, any
such marketing restriction could affect future revenues and have a material
adverse effect on its operations. Watson's earnings may be negatively impacted
if existing collaborative or joint venture partners withdraw or if these
products are not timely developed, approved or successfully commercialized.
 
Product liability claims are a risk and insurance is expensive.
 
  The design, development and manufacture of Watson's products involve an
inherent risk of product liability claims and associated adverse publicity.
Insurance coverage is expensive and may be difficult to obtain, and may not be
available in the future on acceptable terms, or at all. Although Watson
currently maintains product liability insurance for its products in the
amounts Watson believes to be commercially reasonable, we cannot assure you
that the coverage limits of Watson's insurance policies will be adequate. A
claim brought against Watson, whether fully covered by insurance or not, could
have a material adverse effect upon Watson.
 
 Risks Associated With Investing in the Pharmaceutical Industry
 
The pharmaceutical industry is highly competitive.
 
  The pharmaceutical industry is intensely competitive. Watson's competitors
vary depending upon product categories, and within each product category, upon
dosage strengths and drug-delivery systems. Such competitors include the major
brand name and off-patent manufacturers of pharmaceuticals, especially those
doing business in the United States. Many competitors have been in business
for a longer period of time than Watson, have a greater number of products on
the market and have greater financial and other resources. Newly introduced
off-patent products with limited or no off-patent competition are typically
sold at higher selling prices, often resulting in increased gross profit
margins. As competition from other manufacturers intensifies, selling prices
typically decline. Consequently, the maintenance of profitable operations will
depend, in part, on Watson's ability to maintain efficient production
capabilities and to develop and introduce new products in a timely and cost-
effective manner. It is possible that developments by others will make
Watson's products or technologies noncompetitive or obsolete.
 
                                      15
<PAGE>
 
ITEM 2. PROPERTIES
 
  Watson conducts its operations using a combination of owned and leased
properties. The Company believes that its facilities are well maintained and
in good condition. Properties owned by the Company consist of research and
development, manufacturing, warehouse, distribution and administrative
facilities, containing approximately 697,000 square feet in Corona,
California, Copiague, New York, Salt Lake City, Utah and Dayton, Ohio. In
addition, the Company has a majority interest in a 90,000 square foot
manufacturing plant in Changzhou City, People's Republic of China.
 
  Leased properties are located throughout the U.S. and include a distribution
center, research and development, manufacturing, administrative and sales and
marketing facilities. The facilities currently leased by the Company contain
approximately 484,000 square feet and are subject to lease terms that expire,
subject to renewal options, between 1999 and 2005. In addition, the Company
has leased through 2001, a 32,000 square foot manufacturing facility in
Corona, California from a trust in which Watson's Chairman, Chief Executive
Officer and President and the Company's Senior Vice President, Scientific
Affairs have a beneficial interest. 1998 rent expense under this related party
lease was $345,000.
 
  The Company believes that while it currently has sufficient facilities to
conduct its operations during 1999, it will continue to acquire and lease
additional properties as its business requires.
 
ITEM 3. LEGAL PROCEEDINGS
 
  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. The 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. In June 1998, the Federal District Court for the Western District of
Kentucky dismissed all claims against Watson in this action. Royce remains a
defendant in the action and has filed its response denying all relevant
claims. The case is still in discovery. It is contemplated that any material
liability and defense costs will be covered by the Company's product liability
insurance.
 
  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. As of March 15, 1999, 517 cases have been filed against Rugby in state
and federal courts in twenty-one 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. for the defense of all such cases and for any liability which
may arise out of these cases. HMR is currently controlling the defense of all
these matters as the indemnifying party under its agreements with Rugby.
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, governmental and/or
regulatory inspections, investigations and proceedings, and litigation matters
that arise from time to time in the ordinary course of business. The process
of resolving matters through litigation or other means is inherently uncertain
and it is possible that the resolution of these matters may adversely affect
the Company. In management's opinion, however, Watson is not currently

(1)  The Company merged with Circa Pharmaceuticals, Inc. ("Circa"), in July
     1995, with Oclassen Pharmaceuticals, Inc. ("Oclassen"), in February 1997,
     and with Royce, in April 1997. These transactions were accounted for as
     poolings of interests, and accordingly, the consolidated financial data
     include Circa, Oclassen, and Royce for all periods presented.
 
  In October 1997, the Company effected a two-for-one stock split in the form
  of a 100% stock dividend. Share and per share amounts for all reported
  periods have been restated to reflect the stock split.

     Pharmaceuticals, Inc. ("Marsam") of $6.2 million and $3.2 million,
     respectively. The Company has no remaining investment in Marsam.
 
(5)  The gain from legal settlement resulted from the settlement of certain
     lawsuits which Circa was a defendant. All of these lawsuits were settled
     by the first quarter of 1996.
 
ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
        RESULTS OF OPERATIONS
 
  Except for the historical information contained herein, this report,
including the following discussion, contains forward-looking statements that
involve risks and uncertainties. Such risks and uncertainties are discussed in
this report and in the cautionary statement on page 2 of this Form 10-K.
 
GENERAL
 
  The Company derives its revenues from the development, manufacture and sale
of pharmaceutical products. From the Company's founding in 1983 until 1996,
revenues were generated primarily from sales of off-patent versions of branded
pharmaceutical products. Since 1997, Watson has made significant investments
in branded pharmaceutical businesses and products. The Company believes that
branded pharmaceutical products generally offer stronger proprietary positions
and provide more consistent profit margins than off-patent pharmaceutical
products. Although the Company has diversified its product portfolio with
branded products, off-patent products remain an integral component of its
overall business strategy. Through internal product development and
acquisitions, the Company continues to expand its off-patent product
offerings. Watson will continue to consider acquisitions of complementary
products and businesses as a means of broadening its off-patent and branded
product portfolio.
 
ACQUISITIONS IN 1999 AND 1998
 
  Acquisition of TheraTech, Inc. ("TheraTech")--Watson completed its
acquisition of TheraTech in January 1999. TheraTech is a leading drug-delivery
company that developed, manufactured and marketed innovative products based on
its patented and proprietary technologies and systems. Under the terms of the
TheraTech merger agreement, each share of TheraTech common stock was converted
into the right to receive 0.2663 of a share of the Company's common stock.
Accordingly, the Company issued approximately 5.8 million common shares with a
market value on the date of acquisition of approximately $329.0 million in
exchange for all of the outstanding common shares of TheraTech. The
acquisition qualified as a tax-free merger for federal income tax purposes and
will be accounted for as a pooling of interests. The Company's 1998
consolidated financial statements do not reflect the 1999 acquisition of
TheraTech. In the first quarter of 1999, Watson expects to incur a one-time
charge related to this acquisition of approximately $20.0 million. This charge
will include investment banking fees, professional fees and other acquisition
and consolidation-related costs.
 
                                      20
<PAGE>
 
  1998 acquisition of oral contraceptive products from Searle--In November
1998, Watson acquired from Searle the U.S. rights to three oral contraceptive
products, Tri-Norinyl(R), Norinyl(R) and Brevicon(R), for $120.0 million in
cash. In connection with the acquisition, Watson and Searle entered into a
supply agreement whereby Watson has the right to purchase the products from
Searle in finished form for two years and in bulk form for an additional one-
year period.
 
  Acquisition of Rugby--In February 1998, Watson acquired Rugby from Hoechst
Marion Roussel, Inc. Rugby developed, manufactured, and marketed a wide array
of off-patent pharmaceutical products. Under the terms of the acquisition
agreement, the Company acquired Rugby and its abbreviated new drug
applications, which included several licensed products, plus Rugby's sales and
marketing operations for U.S. off-patent and over-the-counter pharmaceutical
products. Rugby's product development group and product development pipeline
were also acquired in the transaction. The Company paid approximately $67.5
million in cash at closing and agreed to contingent payments based on future
sales and operating results. The acquisition was accounted for as a purchase
and Rugby's results of operations have been recorded in the Company's
consolidated financial statements since the date of acquisition. A charge of
$13.0 million for acquired in-process research and development was recorded in
the Rugby acquisition. This charge is discussed further in Note 2 to the
consolidated financial statements.
 
ACQUISITIONS IN 1997 AND EARLIER YEARS
 
  1997 acquisition of oral contraceptive products from Searle--In October
1997, the Company acquired the U.S. rights to certain existing and future
Searle branded off-patent oral contraceptive products. In accordance with this
agreement, cash payments of $51.5 million and $85.0 million were made to
Searle in 1998 and 1997, respectively. Watson and Searle entered into a supply
agreement whereby Watson has the right to purchase the products for two years
from the date of acquisition and, at the Company's election, for an additional
two-year period. Payment for future products is contingent and due upon
receipt of FDA approval. If the FDA approves these future products, the
maximum aggregate acquisition cost for the remaining future products will be
approximately $33.8 million plus certain contingent payments based on the
technology transfer and net aggregate annual sales of certain acquired
products.
 
  Acquisition of product rights to Dilacor XR(R)--In June 1997, the Company
acquired from Rhone-Poulenc Rorer Pharmaceuticals, Inc. ("RPR") the exclusive
U.S. and certain worldwide marketing, sales, and distribution rights to
Dilacor XR(R) for $190.0 million in cash and future royalties. Watson and RPR
entered into a supply agreement whereby Watson has the right to purchase
finished products from RPR through June 1999 and for an additional one-year
period under certain conditions. Prior to the acquisition of the rights to
Dilacor XR(R), the Company earned royalties from RPR sales of Dilacor XR(R).
The Company earned royalties from this product of $14.2 million for the first
six months of 1997 and $27.2 million for the full year of 1996. Dilacor XR(R)
has been available in the U.S. for the treatment of hypertension since June
1992 and was approved for the treatment of chronic stable angina in March
1995. Due to off-patent competition, the Company's product sales and gross
profit from Dilacor XR(R) are likely to continue to decline in future periods.
 
  Acquisition of Royce--In April 1997, the Company acquired Royce for
approximately 5.2 million shares of its common stock having a market value of
approximately $98.0 million at the date of acquisition. Royce developed and
manufactured off-patent prescription drugs in solid dosage forms (tablets and
capsules). The acquisition was accounted for as a pooling of interests and
qualified as a tax-free merger for federal income tax purposes.
 
  Acquisition of Oclassen--In February 1997, the Company acquired Oclassen for
approximately 6.6 million shares of its common stock having a market value of
approximately $135.0 million at the date of acquisition. The acquisition was
accounted for as a pooling of interests for accounting purposes and qualifies
as a tax-free merger for federal income tax purposes. Oclassen marketed
dermatology products used to prevent and treat skin diseases. In connection
with the acquisition, the Company obtained the rights to the following five
Oclassen products: Monodox(R) (doxycycline monohydrate), Condylox(R)
(podofilox 0.5%), Cordran(R) (flurandrenolide), Cinobac(R) (cinoxacin) and
Cormax(TM) (clobetasol propionate).
 
                                      21
<PAGE>
 
  Acquisition of Circa--In July 1995, the Company acquired Circa for
approximately 37.4 million shares of its common stock having a market value of
approximately $698.0 million at the date of acquisition. Circa manufactured
off-patent pharmaceutical products and held investments in Somerset
Pharmaceuticals, Inc. ("Somerset") and Andrx Corporation ("Andrx"). The
acquisition qualified as a tax-free merger for federal income tax purposes and
was accounted for as a pooling of interests.
 
OTHER SIGNIFICANT INVESTMENTS AND JOINT VENTURES
 
  Somerset joint venture--The Company owns 50% of the outstanding shares of
Somerset, which markets the product Eldepryl(R) used for the treatment of
Parkinson's disease. Somerset is also developing additional indications for
selegiline (the active compound of Eldepryl(R)), using a transdermal delivery
system. The Company recorded equity in earnings from this joint venture of
$7.4 million in 1998, $12.7 million in 1997 and $20.1 million in 1996. The
introduction of off-patent competition and Somerset's increased research and
development spending in support of various clinical trials have significantly
reduced Somerset's earnings. Management expects the Company's earnings from
Somerset to continue to decline.
 
  Investment in Andrx--In 1994, the Company acquired a 7.5% interest in Andrx
(Nasdaq:ADRX), a drug-delivery company utilizing controlled-release
technologies to develop oral pharmaceutical products. Watson increased its
ownership of Andrx in October 1995 and in June 1997. At December 31, 1998, the
Company owned 2.7 million common shares of Andrx, which represented
approximately 17.7% of the total Andrx common shares outstanding. The Company
also has a warrant to acquire 337,100 shares of Andrx, exercisable in whole or
in part until July 8, 1999 at an exercise price of $8.90 per share. Watson
accounts for its investment in Andrx using the cost method, adjusted to fair
value. See Item 7A--Quantitative and Qualitative Disclosures About Market Risk
and Note 4 to the consolidated financial statements for further discussion.
 
QUARTERLY FLUCTUATIONS
 
  Watson's quarterly earnings have fluctuated in the past, and may continue to
fluctuate. The Company believes such fluctuations are primarily due to new-
product introductions and to a variety of additional factors including, but
not limited to, purchasing practices of the Company's customers, market
acceptance of Watson's products, the impact of competitive products and
pricing and the timeliness with which regulatory authorizations and product
roll-out may be achieved.

YEARS ENDED DECEMBER 31, 1998 AND 1997
 
  Product sales for the year ended December 31, 1998 were $556.1 million
compared to $324.0 million for the year ended December 31, 1997, an increase
of $232.1 million or 72%. This sales increase was due primarily to i)
increased sales of certain core off-patent and branded products, ii) increased
sales of off-patent products obtained through the Rugby acquisition, and iii)
increased sales of branded products, primarily as a result of the Dilacor
XR(R) acquisition in June 1997 and the Searle oral contraceptive products
which were purchased in October 1997.
 
  The Company earned royalties of $14.2 million in 1997 from RPR sales of
Dilacor XR(R). Subsequent to Watson's June 1997 purchase of the Dilacor XR(R)
product rights, no further royalties were earned.
 
  Research and development expenses increased to $30.8 million in 1998 from
$18.1 million in 1997. This increase was due primarily to the 1998 acquisition
of Rugby's off-patent product development group and increased spending by the
Company's existing development groups.
 
  Selling, general and administrative expenses increased to $88.4 million in
1998 from $50.9 million in 1997. The increase consists of a $30.6 million
increase in sales and marketing expenses and a $6.9 million increase in
general and administrative costs. The increased sales and marketing expenses
were primarily the result of increased sales force personnel costs,
advertising and other promotional expenses incurred in support of the
Company's branded products. General and administrative costs increased during
1998 as a result of increased staffing in certain administrative areas to
support the Company's growth. However, as a percentage of net sales, general
and administrative costs decreased to 3.6% in 1998 from 4.1% in 1997.
 
                                      23
<PAGE>
 
  Amortization expense increased to $22.5 million in 1998 from $7.2 million in
1997 due to the product right acquisitions (Dilacor XR(R) and Searle oral
contraceptive products) and goodwill recorded in the Rugby acquisition.
 
  In connection with the acquisition of Rugby during the first quarter of
1998, the Company recorded a special charge of $13.0 million for the write-off
of in-process research and development associated with Rugby's wholly owned
subsidiary, Chelsea Laboratories, Inc. Watson, in conjunction with an
independent valuation firm, based this charge on an assessment of the value of
purchased research and development at Rugby. This charge is discussed further
in Note 2 to the consolidated financial statements. No such charge was
incurred in 1997.
 
  In 1997, the Company recorded one-time charges of $14.7 million for costs
incurred in connection with the mergers of Royce and Oclassen. These costs
included investment banking fees and other merger-related expenses.
 
  Equity in earnings from joint ventures decreased $3.9 million to $6.8
million in 1998 from $10.7 million in 1997, due primarily to lower earnings
from Somerset. The decrease in Somerset earnings is due in part to increased
competition with respect to Eldepryl(R) (Somerset's sole product) and
increased research and development spending in support of various clinical
trials. Management expects the Company's earnings from Somerset to continue to
decline.
 
  Investment and other income decreased to $6.6 million in 1998 from $12.0
million in 1997 due to lower average cash and marketable securities balances
in 1998. The lower average cash and marketable securities balances in 1998
were due to the Company's acquisition-related activities.
 
  Interest expense during 1998 increased to $7.1 million from $347,000 in 1997
as a result of the Company's $150.0 million senior debt issuance in May 1998.
These notes have a stated annual interest rate of 7 1/8% and were sold at a
discount to yield an effective annual interest rate of 7 1/4% to the Company.
 
  The provision for income taxes increased to $78.2 million in 1998, compared
to $54.4 million in 1997. The effective income tax rate was 39% and 38% for
the years ended December 31, 1998 and 1997, respectively. The increase in the
Company's effective income tax rate was due primarily to the non-deductibility
for income tax purposes of the $13.0 million in-process research and
development charge incurred as a result of Watson's acquisition of Rugby.
 
YEARS ENDED DECEMBER 31, 1997 AND 1996
 
  Revenues for the year ended December 31, 1997 were $338.3 million compared
to $250.8 million for the year ended December 31, 1996, an increase of $87.5
million or 34.9%. The increase in revenues was composed of a $100.4 million
increase in product sales, partially offset by a $12.9 million decrease in
royalty income. The increase in product sales was largely due to sales of
Dilacor XR(R), which was purchased from RPR in June 1997. The Company also
experienced increased sales of dermatology products, oral contraceptives, core
off-patent products and new products approved or acquired during the year.
These sales increases were partially offset by decreased sales of certain
strengths in the Company's hydrocodone product line.
 
  Royalty income decreased $12.9 million or 47.5% in 1997 as compared with
1996 due to the Company's June 1997 acquisition from RPR of the Dilacor XR(R)
product rights. Following this acquisition, no further royalties were earned.
 
  Gross profit margins increased to 61.4% in 1997 from 54.4% in 1996. The
increase in gross profit margins was due largely to sales of Dilacor XR(R),
higher sales of branded dermatology products and sales of products introduced
in 1997. The increased gross profit margins from these products was partially
offset by reduced gross profit margins of certain core off-patent products.
 
  Research and development expenses decreased to $18.1 million in 1997 from
$22.9 million in 1996. Following the mergers with Royce and Oclassen, the
Company consolidated certain research and development functions and eliminated
duplicate programs.
 
                                      24
<PAGE>
 
  Selling, general and administrative expenses increased to $50.9 million in
1997 from $38.9 million in 1996. The increase consists of a $16.8 million
increase in sales and marketing expenses and a $4.8 million decrease in
general and administrative costs. The Company incurred increased sales and
marketing costs as it expanded its marketing efforts for branded products. The
Company increased its sales force from approximately 20 representatives in
late 1996 to more than 300 at December 31, 1997.
 
  As a result of the mergers of Royce and Oclassen with Watson, and the
subsequent consolidation of many of the administrative functions, the Company
has experienced a decrease in its general and administrative expenses. As a
percentage of net sales, general and administrative costs decreased from 8.1%
in 1996 to 4.1% in 1997. This decrease reflects efficiencies achieved
following the mergers and the fact that the Company's sales growth outpaced
the growth in administrative costs.
 
  Amortization expense in 1997 increased to $7.2 million from $386,000 due to
several significant product right acquisitions during the year. The Company
amortizes these acquired product rights over 17 years.
 
  In 1997, the Company recorded one-time charges of $14.7 million for costs
incurred in connection with the mergers with Royce and Oclassen. These costs
included investment banking fees and other merger-related expenses. No such
expenses were incurred in 1996.
 
  Equity in earnings from joint ventures decreased $7.2 million or 40.2% to
$10.7 million in 1997 compared to $17.9 million in 1996, due primarily to
lower earnings from Somerset. The decrease in Somerset earnings is due in part
to the loss of exclusivity for Eldepryl(R) in June 1996. During 1997 and 1996,
a number of competitors introduced off-patent tablets to compete with
Eldepryl(R) capsules. Increased competition and research and development
spending in support of various clinical trials have significantly reduced
Somerset's contribution to the Company's operating results.
 
  Investment and other income increased 16.5% to $12.0 million in 1997 from
$10.3 million in 1996 due to higher average cash and marketable securities
balances in 1997.
 
  The provision for income taxes increased to $54.4 million in 1997, compared
to $35.9 million in 1996. The effective income tax rate was 38% and 31% for
the years ended December 31, 1997 and 1996, respectively. The increase in the
Company's effective income tax rate was due primarily to the non-deductibility
of a significant portion of merger expenses incurred in 1997 and lower
earnings from Somerset which are partially exempt from tax.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  The Company's working capital increased to $198.5 million at December 31,
1998 from $146.9 million at December 31, 1997. This $51.6 million increase was
primarily due to cash flows from operations ($117.7 million) and proceeds from
the offering of senior notes ($148.4 million), offset by the acquisition of
women's health products ($120.0 million), the acquisition of Rugby ($67.5
million) and capital expenditures ($26.5 million). The Company's $26.5 million
of capital investment in 1998 consisted primarily of additions to land,
buildings and manufacturing and laboratory equipment. Watson expects to invest
approximately $40.0 million in capital expenditures during 1999.
 
  In April 1998, the Company filed a registration statement with the
Securities and Exchange Commission which allows Watson to raise up to $300.0
million from offerings of senior or subordinated debt securities, common
stock, preferred stock or a combination thereof, at such times and in such
amounts as Watson deems appropriate. In May 1998, pursuant to this
registration statement, the Company issued $150.0 million of 7 1/8% senior
unsecured notes (the "Senior Notes"). The Company had notes payable
outstanding of approximately $150.9 million at December 31, 1998. These notes
consist of the Senior Notes and other notes payable of approximately $2.4
million. The Senior Notes are due May 2008, with interest-only payments due
semi-annually in November and May.
 
                                      25
<PAGE>
 
  In January 1999, the Company made a scheduled payment of $30.0 million
pursuant to the purchase of the product rights to Dilacor XR(R). Additional
payments of $15.0 million and $5.0 million will be due in January 2000 and
January 2001, respectively.
 
  The Company's cash and marketable securities totaled $72.7 million at
December 31, 1998. Management believes that the Company's cash and marketable
securities, plus cash flow from operations will be sufficient to meet its
normal operating requirements during the coming year.
 
  The Company continues to review additional opportunities to acquire or
invest in companies, technologies, product rights and other investments that
are compatible with its existing business. Watson could use sources other than
cash, such as offerings under the registration statement discussed herein or
other such registration statements, to fund additional acquisitions or
investments. If any such acquisition or investment is completed, the Company's
operating results and financial condition could change materially in future
periods.
 
  Management believes inflation does not have, and has not had, a significant
impact on the Company's revenues or operations.
 
YEAR 2000 COMPLIANCE PROGRAM
 
  Watson has instituted a multi-phase program to (a) evaluate whether its
computerized information systems are able to interpret dates beyond the year
1999, (b) to respond to and remedy any inadequacies which may emerge from the
evaluation process, (c) to investigate the Year 2000 readiness of third
parties having material relationships with the Company and (d) to develop a
contingency plan for any Year 2000 date sensitive systems of the Company,
which may not be immediately remedied (the "Year 2000 Compliance Program"). An
inability to interpret dates beyond 1999 could cause computer system errors or
system failure, potentially leading to disruptions in operations. The
aggregate cost of Watson's Year 2000 Compliance Program is expected to be
approximately $500,000. The scope of the Company's Year 2000 Compliance
Program was initially focused on Watson's primary business application
systems, including manufacturing, sales, distribution and finance. The
evaluation and remedy phases have been completed for these business units and
management believes that these systems are currently Year 2000 compliant.
Additionally, the Company is evaluating all internal network systems, personal
computers and telecommunications systems. These systems are expected to be
Year 2000 compliant by approximately April 1999. In the third quarter of 1998,
Watson began the third phase in its Year 2000 Compliance Program, which is a
review of external entities having material relationships with the Company.
Communications with these entities is underway and the Company expects this
phase to be completed by June 1999.
 
  Watson is developing a contingency plan for unanticipated Year 2000 exposure
as part of its overall efforts to ensure that its systems are Year 2000
compliant on a timely basis. This contingency plan includes the procurement of
additional raw material, packaging material and finished goods inventory, the
installation of back-up power generation systems and the implementation of
parallel procedures in key operating areas, among other measures.
 
  The Company's management believes that an adequate program is in place in
order to be Year 2000 compliant, however, there can be no assurance that this
program ultimately will be successful. Any unanticipated failure in the
Company's internal systems to be Year 2000 compliant, or any failure by a
material third party to bring its own systems into compliance, could have a
material adverse effect on Watson's business, its financial position and its
results of operations.
 
  The foregoing represents a Year 2000 readiness disclosure entitled to
protection as provided in the Year 2000 Information and Readiness Disclosure
Act.

NEW ACCOUNTING PRONOUNCEMENTS
 
  In 1998, the Company adopted Financial Accounting Standards No. 131,
"Disclosures about Segments of an Enterprise and Related Information," (FAS
131). FAS 131 supercedes FAS 14, "Financial Reporting for Segments of a
Business Enterprise," and replaces the "industry segment" approach with the
"management" approach. The management approach designates the internal
organization that is used by management for making operating decisions and
assessing performance as the source of the Company's reportable segments.
Watson has one reportable segment, pharmaceutical products.
 
  In 1998, the Company adopted Financial Accounting Standards No. 130,
"Reporting Comprehensive Income," (FAS 130). FAS 130 established new rules for
the reporting and display of comprehensive income and its components in the
financial statements. Comprehensive income includes all changes in equity
during a period except those resulting from investments by and distributions
to the Company's stockholders. Watson's comprehensive income is comprised of
net income and the unrealized gain on equity securities. The adoption of FAS
130 had no effect on the Company's consolidated results of operations,
financial position or cash flows.
 
  In March 1998, the American Institute of Certified Public Accountants issued
Statement of Position (SOP) 98-1, "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use." This SOP provides guidance
on accounting for certain costs in connection with obtaining or developing
computer software for internal use and requires that entities capitalize such
costs once certain criteria are met. The Company is required to adopt SOP 98-1
as of January 1, 1999.
 
ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
 
  Substantially all of the Company's cash equivalents and marketable
securities are at fixed interest rates and, as such, the fair value of these
instruments is affected by changes in market interest rates. However, all of
the Company's cash equivalents and marketable securities mature within one
year. As a result, the Company believes that the market risk arising from its
holding of these financial instruments is minimal.
  The Company's investment in Andrx, which was stated on Watson's balance
sheet at a fair value of $138.0 million at December 31, 1998, is composed of
2.7 million shares of Andrx common stock. Andrx' common stock is a publicly
traded equity security, and therefore, has exposure to price risk. The
following table sets forth the Andrx quarterly high and low share price
information for 1997 and 1998:

the results of their operations and their cash flows for each of the three
years in the period ended December 31, 1998, 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, as of December 31, 1997 and for the
years ended December 31, 1997 and 1996. The Company's investment in Somerset
aggregated $27,643,000 at December 31, 1997, and its equity in the earnings of
Somerset totaled $12,672,000 and $20,100,000 for the years ended December 31,
1997 and 1996, respectively. In addition, we did not audit the financial
statements of Oclassen Pharmaceuticals, Inc. (Oclassen), a wholly owned
subsidiary, for the year ended December 31, 1996, which statements reflect
total revenues of $34,421,000 for the year ended December 31, 1996. Those
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 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 branded and off-patent
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., Circa Pharmaceuticals, Inc. ("Circa"), Oclassen
Pharmaceuticals, Inc. ("Oclassen"), Royce Laboratories, Inc. ("Royce") and The
Rugby Group, Inc. ("Rugby"). Watson acquired certain of these subsidiaries
through acquisitions in 1998 and earlier years. See Note 2 for further
information on the Company's merger and acquisition activities.
 
  Investments are accounted for under the equity method where the Company can
exert significant influence and ownership does not exceed 50% (primarily
Somerset Pharmaceuticals, Inc.) Investments in which the Company holds less
than a 20% interest and does not exert significant influence are accounted for
under the cost method, adjusted to fair value. The Company's investment in
Andrx Corporation ("Andrx") is accounted for under the cost method.
 
 Cash equivalents and marketable securities
 
  Cash equivalents are highly liquid investments with original maturities of
three months or less at the date of acquisition. Marketable securities consist
primarily of time deposits, commercial paper, U.S. and state and local
government debt with original maturities between three and twelve months.
 
  The Company accounts for investments in accordance with Financial Accounting
Standards No. 115 (FAS 115), "Accounting for Certain Investments in Debt and
Equity Securities." Under FAS 115, debt securities that the Company does not
have the positive intent and ability to hold to maturity and all marketable
equity securities are carried at fair market value and are classified as
either trading or available-for-sale securities. All of the Company's cash
equivalents and marketable 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, 1998, 1997 and 1996.
 
  The fair value of cash, cash equivalents and marketable securities is
summarized as follows:

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
 
 Fair value of financial instruments
 
  The carrying amounts of cash and cash equivalents, marketable securities,
accounts receivable, accounts payable and accrued expenses 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,
1998 and 1997.
 
 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 are amortized on the straight-line basis over the shorter of the
respective lease terms or the estimated useful life of the assets, and
generally range from five to thirty years.
 
 Product rights and other intangible assets
 
  Product rights are stated at cost, less accumulated amortization, and are
amortized on the straight-line basis over their estimated useful lives ranging
from seventeen to twenty five years. Goodwill is amortized on the straight-
line basis over twenty years or less and is primarily related to the Company's
acquisition of Rugby (Note 2). Accumulated amortization was $39.1 million and
$15.6 million at December 31, 1998 and 1997, 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 1998, two customers accounted for 17% and 12%, individually, of the
Company's product sales. In 1997, two customers accounted for 12% and 11%,
individually, of the Company's product sales. In 1996, one customer accounted
for 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--(Continued)
 
 
 Income taxes
 
  Income taxes are accounted for using an asset and liability approach that
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 Financial Accounting Standards No. 128,
"Earnings per Share," (FAS 128). In accordance with the implementation
provisions of FAS 128, the Company has restated earnings per share in its
consolidated statements of income for the year ended December 31, 1996. The
unaudited quarterly data for the first three quarters of 1997 presented in
Note 10 have also been restated to comply with the provisions ofFAS 128. A
reconciliation of the numerators and the denominators of basic and diluted
earnings per share for the years ended December 31, 1998, 1997, and 1996 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
accounts receivable balance, all of which is due from service providers,
distributors, wholesalers and chain drug stores in the health care and
pharmaceutical industries throughout the United States. At December 31, 1998
and 1997, approximately 57% and 27%, respectively, of the trade receivable
balances represented amounts due from four customers in 1998 and two customers
in 1997. The Company performs ongoing credit evaluations of its customers and
maintains reserves for potential uncollectible accounts. Actual losses from
uncollectible accounts have been minimal.

 Recent accounting pronouncements
 
  In 1998, the Company adopted Financial Accounting Standards No.131,
"Disclosures about Segments of an Enterprise and Related Information," (FAS
131). FAS 131 supercedes FAS 14, "Financial Reporting for Segments of a
Business Enterprise," and replaces the "industry segment" approach with the
"management" approach. The management approach designates the internal
organization that is used by management for making operating decisions and
assessing performance as the source of the Company's reportable segments.
Watson has one reportable segment, pharmaceutical products.
 
  In 1998, the Company adopted Financial Accounting Standards No. 130,
"Reporting Comprehensive Income," (FAS 130). FAS 130 established new rules for
the reporting and display of comprehensive income and its components in the
financial statements. Comprehensive income includes all changes in equity
during a period except those resulting from investments by and distributions
to the Company's stockholders. Watson's comprehensive income is comprised of
net income and the unrealized gain on equity securities. The adoption of FAS
130 had no effect on the Company's consolidated results of operations,
financial position or cash flows.
 
  In March 1998, the American Institute of Certified Public Accountants issued
Statement of Position (SOP) 98-1, "Accounting for the Costs of Computer
Software Developed or Obtained for Internal Use." This SOP provides guidance
on accounting for certain costs in connection with obtaining or developing
computer software for internal use and requires that entities capitalize such
costs once certain criteria are met. The Company is required to adopt SOP 98-1
as of January 1, 1999.
 
 Reclassifications
 
  Certain amounts in the 1996 and 1997 financial statements have been
reclassified to conform with the 1998 presentation. These reclassifications
had no effect on net income or retained earnings.
 
2. Mergers and Acquisitions
 
 Subsequent event--acquisition of TheraTech
 
  In January 1999, Watson's acquisition of TheraTech was completed. TheraTech
is a leading drug-delivery company that developed, manufactured and marketed
innovative products based on its patented and proprietary technologies and
systems. Under the terms of the TheraTech merger agreement, each share of
TheraTech common stock was converted into the right to receive 0.2663 of a
share of the Company's common stock. Accordingly, the Company issued
approximately 5.8 million common shares having a market value of approximately
$329 million on the date of acquisition in exchange for all of the outstanding
common shares of TheraTech. The acquisition qualified as a tax-free merger for
federal income tax purposes and will be accounted for as a pooling of
interests. The Company's 1998 consolidated financial statements do not reflect
the 1999 acquisition of TheraTech. In the first quarter of 1999, Watson
expects to incur a one-time charge related to this acquisition of
approximately $20.0 million. This charge will include investment banking fees,
professional fees and other costs related to consolidating the operations of
the two companies.
 
 1998 acquisition of oral contraceptive products from Searle
 
  In November 1998, Watson acquired the U.S. rights to three Searle oral
contraceptive products for $120.0 million in cash. Watson and Searle have
entered into a supply agreement whereby Watson has the right to purchase from
Searle the products in finished form for two years and in bulk form for an
additional one year period.

 Acquisition of Rugby
 
  In February 1998, Watson completed its acquisition of Rugby from Hoechst
Marion Roussel, Inc. Rugby developed, manufactured and marketed a wide array
of off-patent pharmaceutical products. Under the terms of the agreement, the
Company acquired Rugby and its abbreviated new drug applications, which
included several licensed products, plus Rugby's sales and marketing
operations for U.S. off-patent and over-the-counter pharmaceutical products.
The transaction also included Rugby's product development group and product
development pipeline. Under the terms of the acquisition agreement, the
Company paid approximately $67.5 million in cash at closing and agreed to
contingent payments based on future sales and operating results. The
acquisition was accounted for as a purchase and Rugby's results of operations
have been recorded in the Company's consolidated financial statements since
the date of acquisition. The excess of the aggregate purchase price over the
fair value of the assets acquired was approximately $30.9 million and is being
amortized over 20 years.
 
  Under the purchase method of accounting, the purchase price is generally
allocated to the acquired assets and liabilities based on their estimated fair
values at the date of acquisition. However, the portion of the purchase price
that is allocated to in-process research and development (IPR&D) is not an
asset, but instead, represents the valuation of acquired, to-be-completed
research projects. As such, the amount that is determined to be IPR&D is
charged to expense at the date of acquisition. In the first quarter of 1998,
in connection with the Rugby acquisition, the Company charged $18.8 million to
IPR&D. This amount was subsequently adjusted to $13.0 million to reflect a
recently revised Securities and Exchange Commission-preferred methodology for
valuing IPR&D.
 
  Watson acquired 13 separate IPR&D projects from Rugby, none of which were
material on an individual basis to the Company. Rugby commenced work on these
projects, all of which relate to the development of off-patent pharmaceutical
drugs, at various dates beginning in late 1994. The Company, in conjunction
with an independent valuation firm, determined the allocation of purchase
price to acquired IPR&D. At the acquisition date, it was estimated that the
acquired projects, on an overall basis, were approximately 70% complete and
would require approximately $8.8 million to complete. The primary factor
considered in determining the amount charged to IPR&D was the estimated future
cash flows of each project. Discount rates that ranged from 16% to 20% were
assigned to each project based on identified risk factor assumptions. The
discounted cash flows were then adjusted by the completion percentages of each
project, as of the acquisition date. The individual project completion
percentages were estimated by dividing project costs incurred through the
acquisition date by the costs expected to complete each project.
 
  The development of pharmaceutical products is subject to numerous risks and
uncertainties including formulation and manufacturing issues, the FDA approval
and monitoring process and competitive risks in the marketplace, among others.
There can be no assurance that any of these projects will achieve full
development, receive the required regulatory approvals or contribute in any
significant manner to Watson's future sales.
 
  Significant acquisitions in 1997 and earlier years are summarized below:
 
 1997 acquisition of oral contraceptive products from Searle
 
  In October 1997, the Company acquired the U.S. rights to certain existing
and future Searle branded off-patent oral contraceptive products. In
accordance with this agreement, cash payments of $51.5 million and
$85.0 million were made to Searle in 1998 and 1997, respectively. Watson and
Searle entered into a supply agreement whereby Watson has the right to
purchase the products for two years from the date of acquisition and,

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 
at the Company's election, for an additional two-year period. Payment for
future products is contingent and due upon receipt of FDA approval. If the FDA
approves these future products, the maximum aggregate acquisition cost for the
remaining future products will be approximately $33.8 million plus certain
contingent payments based on the technology transfer and net aggregate annual
sales of certain of the acquired products.
 
 1997 acquisition of product rights to Dilacor XR(R)
 
  In June 1997, the Company acquired from Rhone-Poulenc Rorer Pharmaceuticals,
Inc. ("RPR") the exclusive U.S. and certain worldwide marketing, sales, and
distribution rights to Dilacor XR(R) for $190.0 million in cash and future
royalties. Watson and RPR entered into a supply agreement whereby Watson has
the right to purchase finished product from RPR through June 1999 and for an
additional one-year period under certain conditions. Prior to the acquisition
of the rights to Dilacor XR(R), the Company earned royalties from RPR sales of
Dilacor XR(R). The Company earned royalties from this product of $14.2 million
for the first six months of 1997 and $27.2 million for the full year of 1996.
Dilacor XR(R) has been available in the U.S. for the treatment of hypertension
since June 1992 and was approved for the treatment of chronic stable angina in
March 1995.
 
 1997 acquisition of Royce
 
  In April 1997, the Company acquired Royce for approximately 5.2 million
shares of its common stock having a market value of approximately $98.0
million at the date of acquisition. Royce developed and manufactured off-
patent prescription drugs in solid dosage forms (tablets and capsules). The
acquisition was accounted for as a pooling of interests and the transaction
qualified as a tax-free merger.
 
 1997 acquisition of Oclassen
 
  In February 1997, the Company acquired Oclassen for approximately 6.6
million shares of its common stock having a market value of approximately
$135.0 million at the date of acquisition. The acquisition was accounted for
as a pooling of interests for accounting purposes and qualified as a tax-free
merger for federal income tax purposes. Oclassen marketed dermatology products
used to prevent and treat skin diseases. In connection with the acquisition,
the Company obtained the rights to the following five Oclassen products:
Monodox(R) (doxycycline monohydrate), Condylox(R) (podofilox 0.5%), Cordran(R)
(flurandrenolide), Cinobac(R) (cinoxacin) and Cormax(TM) (clobetasol
propionate).
 
 1995 acquisition of Circa
 
  In July 1995, the Company acquired Circa for approximately 37.4 million
shares of its common stock having a market value of approximately $698.0
million at the date of acquisition. Circa manufactured off-patent
pharmaceutical products and held investments in Somerset and Andrx. The
acquisition qualified as a tax-free merger for federal income tax purposes and
was accounted for as a pooling of interests.

 Long-term investments
 
  Long-term investments consist primarily of the Company's investment in
Andrx. Andrx is a drug-delivery company utilizing controlled-release
technologies to develop oral pharmaceutical products. Andrx' common

stock trades on the Nasdaq Stock Market under the symbol ADRX. At December 31,
1998, the Company owned 2.7 million common shares of Andrx, which represents
approximately 17.7% of the total Andrx common shares outstanding. The Company
also has a warrant to acquire 337,100 shares of Andrx, exercisable in whole or
in part until July 8, 1999 at an exercise price of $8.90 per share. The
Company's unrealized gain on this investment was $60.6 million and $33.1
million (net of income taxes of $40.4 million and $22.1 million), at December
31, 1998 and 1997, respectively. The unrealized gain on Andrx is the primary
component of accumulated other comprehensive income in the stockholders'
equity section of Watson's consolidated balance sheets.
 
 Investment in 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. Earnings from Somerset were approximately
$7.4 million, $12.7 million, and $20.1 million in 1998, 1997, and 1996,
respectively. The Somerset joint venture earnings reported by Watson are
comprised of 50% 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 $5.4 million and $6.4 million at
December 31, 1998 and 1997, respectively. Such goodwill is amortized on the
straight-line basis over 15 years.
 
  The Internal Revenue Service ("IRS") has notified Somerset 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 tax credits claimed
under Internal Revenue Code Section 936. The proposed adjustments amount to
approximately $14.0 million of additional income tax and interest charges, 50%
of which would be Watson's share. Management of Somerset believes that it has
met all of the requirements to qualify for the tax credits claimed and intends
to vigorously defend its position on this matter.

  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 $13.6 million, $10.9 million and
$7.8 million for the years ended December 31, 1998, 1997 and 1996,
respectively. Income taxes of $2.3 million have been provided for the possible
distribution of approximately $29.0 million of undistributed earnings related
to the Company's investments in joint ventures.

  The Company had net operating loss ("NOL") carryforwards at December 31,
1998 of approximately $9.0 million and $6.0 million for federal and Florida
state income tax purposes, respectively. During 1998, the Company utilized NOL
carryforwards of approximately $7.0 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, 1998, 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. At December 31, 1998, the Company had reserved 9.9 million shares
of its common stock for issuance upon exercise of options granted or to be
granted under these plans. 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 certain of the Company's acquisitions, Watson assumed stock option and
warrant plans from the acquired companies. The options and warrants in these
plans were adjusted by the individual exchange ratios specified in each
transaction. No additional options or warrants will be granted under any of
the assumed plans.
 
  The Company has elected to follow Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees" (APB 25), and related
interpretations, which require compensation expense for options to be
recognized when the market price of the underlying stock exceeds the exercise
price on the date of the grant. Financial Accounting Standards No. 123,
"Accounting for Stock-Based Compensation" (FAS 123), permits companies to
apply existing accounting rules under APB 25 and provide pro forma disclosures
of net income and earnings per share as if the fair value method (as defined
in FAS 123) had been applied. Had compensation cost been determined using the
fair value method prescribed by FAS 123, the Company's net income and earnings
per share would have been as follows:

  The weighted average fair value of the options has been estimated on the
date of grant using the Black-Scholes option pricing model with the following
weighted average assumptions used for grants in 1998, 1997 and 1996,
respectively: no dividend yield; expected volatility of 41%, 49% and 51%,
risk-free interest rate of 5.14%, 6.15% and 6.18% per annum; and expected
terms ranging from approximately seven to eight years. Weighted averages are
used because of varying assumed exercise dates.

 Legal matters

impact on the Company's consolidated financial position or results of
operations.

  The quarterly data above were restated, as applicable, to reflect the
adoption of FAS 128 and for acquisitions in 1997 accounted for under the
pooling of interests method as further discussed in Note 2. In addition, a
first quarter 1998 charge for acquired in-process research and development
(IPR&D) was restated to reflect a recently revised Securities and Exchange
Commission-preferred methodology for valuing IPR&D. The restated amount is
$13.0 million, as compared to $18.8 million as originally reported, and was
determined in conjunction with an independent valuation firm.

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

                                      -9-
<PAGE>
 
written notice of Borrowing which Bank believes in good faith to have been given
by a Person duly authorized to borrow on behalf of Borrower.

          (d) Reduction of the Revolving Commitment. Borrower shall have the
          -----------------------------------------
right, upon at least 2 Business Days prior written notice to Bank, to terminate
in whole or reduce in part the unused portion of the Revolving Commitment,
without premium or penalty, provided that each partial reduction shall be in the
aggregate amount of $3,000,000 or an integral multiple thereof and that such
reduction shall not reduce the Revolving Commitment to an amount less than the
amount of the Revolving Loans and all L/Cs outstanding hereunder on the
effective date of the reduction. Such notice shall be irrevocable and such
reduction shall not be reinstated.

          (e)  Revolving Note. The Revolving Loans made by Bank pursuant hereto
          -------------------
shall be evidenced by a promissory note of Borrower, substantially in the form
of Exhibit A, with any appropriate insertions (the "Revolving Note"), payable to
   ---------                                        --------------
the order of Bank and representing the obligation of Borrower to pay the
aggregate unpaid principal amount of all Revolving Loans made by Bank, with
interest thereon as prescribed in Section 2.3. Bank hereby is authorized to
record in its books and records and on any schedule annexed to the Revolving
Note, the date and amount of each Revolving Loan made by Bank, and the date and
amount of each payment of principal thereof, and in the case of Libor Rate
Option Revolving Loans, the Libor Rate, the Libor Rate Portion, and the Rate
Period with respect thereto, and any such recordation shall constitute prima
                                                                       -----
facie evidence of the accuracy of the information so recorded; provided that
- -----
failure by Bank to effect such recordation shall not affect Borrower's
obligations hereunder. Prior to the transfer of a Revolving Note, Bank shall
record such information on any schedule annexed to and forming a part of such
Revolving Note.

     .2  Repayment.
     -------------

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

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

                                      -10-
<PAGE>
 
prepayment, specifying the date, amount, and type of prepayment, and upon such
date the amount so specified, accrued interest thereon, and any amounts payable
under Section 3.6(b) shall be due and payable.

     .3  Interest Rate and Payment Dates.
     -----------------------------------

          (a)  Payment. The principal balance of the Note shall be paid in
          ------------
accordance with the terms set forth in the Note. Accrued interest on the Base
Rate Portion shall be due and payable on the first Business Day of each month
commencing on March 1, 1999. Interest on each Rate Segment of the Libor Rate
Portion which has a Rate Period of less than three months shall be due and
payable on the last day of the Rate Period. Interest on each Rate Segment of the
Libor Rate Portion which has a Rate Period longer than three months shall be due
and payable on each three month anniversary of the commencement date of the Rate
Period and on the last day of the Rate Period. After maturity of any part of a
Note (by acceleration or otherwise), interest on such part of the Note shall be
due and payable ON DEMAND.

          (b)  Interest Rate. The unpaid principal amount of the Note shall bear
          ------------------
interest for each day until due on one or more bases selected by Borrower from
among the interest rate options (the "Interest Rate Options") set forth below.
                                      ---------------------
Borrower understands and agrees: (i) that Bank may from time to time determine
that the right of Borrower to select, convert to, or renew the Libor Rate Option
is not available, which availability shall not be unreasonably withheld, (ii)
that Borrower shall not have the right to select, convert to, or renew the Libor
Rate Option at any time that a Default or Event of Default has occurred and is
continuing, and (iii) that subject to the provisions hereof, Borrower may select
any number of options to apply simultaneously to different parts of the unpaid
principal amount of the Note and may select any number of Rate Segments to apply
simultaneously to different parts of the Libor Rate Portion.

                        Available Interest Rate Options
                        -------------------------------

          Base Rate Option:  A rate per annum for each day equal to the Base
          ----------------                                                  
Rate.

          Libor Rate Option:  A rate per annum for each day equal to the Libor
          -----------------                                                   
Rate for such day plus the then applicable Libor Rate Margin.

          (c)  Rate Periods. At any time when Borrower selects, converts to, or
          -----------------
renews the Libor Rate Option, Borrower shall fix a period (the "Rate Period")
                                                                -----------
which shall be one, two, three, or six months, during which the Libor Rate
Option shall apply to the corresponding Rate Segment; provided, that Borrower
                                                      --------
may not elect a Rate Period interest under the Note shall in no way be affected
by the fact that one or more Rate Periods may be in effect.

                                      -11-
<PAGE>
 
          (d)  Interest After Maturity. Upon the occurrence and during the
          ----------------------------    
continuation of an Event of Default, the principal amount of any part of the
Base Rate Portion shall bear interest for each day until paid (before and after
judgment) at a rate per annum (based on a year of 365 days and actual days
elapsed) which for each day shall be the greater of (a) 2% above the Base Rate
Option on the day such amount became due, and (b) 2% above the Base Rate Option,
such interest rate to change automatically from time to time effective as of the
effective date of each change in the Base Rate. Upon the occurrence and during
the continuation of an Event of Default, the principal amount of any part of the
Libor Rate Portion shall bear interest for each day until paid (before and after
judgment) (a) until the end of the applicable then current Rate Period at a rate
per annum 2% above the Libor Rate Option otherwise applicable to such part, and
(b) thereafter in accordance with the previous sentence.

          (e) Selection, Conversion or Renewal of Rate Options. Subject to the
          ----------------------------------------------------
other provisions hereof, Borrower may select any Interest Rate Option to apply
to the borrowings evidenced by the Note. Subject to the other provisions hereof,
Borrower may convert any part of the unpaid principal amount of the Note from
any Interest Rate Option to the other Interest Rate Option: (a) at any time with
respect to the conversion from the Base Rate Option to the Libor Rate Option,
and (b) at the expiration of any Rate Period with respect to conversion from or
renewals of the Libor Rate Option as to the Rate Segment corresponding to such
expiring Rate Period (or at any other time, subject to Section 3.6(b)). Whenever
Borrower desires to select, convert, or renew the Libor Rate Option, Borrower
shall give Bank a Standard Notice thereof (which shall be irrevocable),
specifying the date, amount, and type of the proposed new Rate Option. If such
notice has been duly given, and if Bank approves the proposed selection,
conversion, or renewal, on and after the date specified in such notice, interest
shall be calculated upon the unpaid principal amount of the Note taking into
account such selection, conversion or renewal.

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

                                      -12-
<PAGE>
 
principal amount of the Note subject to the Libor Rate Option shall
accrue interest at the Base Rate Option and Borrower shall not have the right to
select the Libor Rate Option.

     .4  Letters of Credit and Letter of Credit Guarantees.
     -----------------------------------------------------

          (a) Subject to the terms and conditions of this Agreement, and it
being understood that the letter of credit facility provided for under this
Section 2.4 is a sublimit of the credit facility extended pursuant to Section
2.1, Bank agrees to issue standby letters of credit ("Standby L/Cs") and
commercial letters of credit ("Commercial L/Cs") for the account of Borrower
(collectively, Standby L/Cs and Commercial L/Cs shall be referred to herein as
"L/Cs") in an aggregate face amount at any time outstanding not to exceed
$10,000,000.  Each L/C shall have an expiry date no longer than one year, and
all such L/Cs shall be in form and substance reasonably acceptable to Bank.  The
expiry date of an L/C may extend to up to 364 days past the Maturity Date.  Bank
shall not have any obligation to issue L/Cs to the extent that the available
undrawn amount of all outstanding L/Cs, plus the amount of the Revolving Loans
outstanding pursuant to Section 2.1, would exceed the Revolving Commitment.  The
L/Cs issued under this Section 2.4 shall be used by Borrower, consistent with
this Agreement, for its general working capital purposes or other corporate
purposes.  If Bank is obligated to advance funds under an L/C, the amount so
advanced immediately shall be deemed to be a Revolving Loan made by Bank to
Borrower pursuant to Section 2.1 and, thereafter, shall bear interest at the
rates then applicable under Section 2.3.  Borrower further agrees to execute the
Bank's standard application for standby letters of credit, as required by Bank.

          (b) Borrower hereby agrees to indemnify, save, defend, and hold Bank
harmless from any loss, cost, expense, or liability, including payments made by
Bank, expenses, and reasonable attorneys fees incurred by Bank, arising out of
or in connection with any L/Cs, provided that the same does not arise out of
Bank's gross negligence or willful misconduct or the violation of this Agreement
by Bank.  Borrower agrees to be bound by the Bank's regulations and
interpretations of any L/C issued by Bank to or for Borrower's account, even
though this interpretation may be different from Borrower's own, and Borrower
understands and agrees that Bank shall not be liable for any error, negligence,
or mistakes, whether of omission or commission, in following Borrower's
instructions or those contained in the L/C's or any modifications, amendments,
or supplements thereto, provided that the same does not arise out of Bank's
gross negligence or willful misconduct or the violation of this Agreement by
Bank.  The issuance of any L/C and any amendment to any L/C is subject to the
Bank's written approval and must be in form and content satisfactory to Bank and
in favor of a beneficiary acceptable to Bank in its reasonable credit judgement.

          (c) Borrower will pay to Bank on or prior to the date of issuance of
any Commercial L/C, a fee equal to Bank's standard issuance fee applicable to
similar commercial letters of credit at the time of such issuances.  Borrower
will pay to Bank with respect to each Standby L/C, a per annum fee, payable
quarterly in arrears, on or before the first Business Day after the end of each
such quarter, equal to the average undrawn amount of 

                                      -13-
<PAGE>
 
such L/C during the quarter multiplied by the applicable Libor Rate Margin,
based on a year of 365 days. Service charges, commissions, fees, and costs may
be charged at the Bank's customary rates with respect to routine services
relating to L/Cs and paid by Borrower at the time the service is rendered or the
cost is incurred.

          (d) Immediately upon the termination of this Agreement, Borrower
agrees to either:  (i) provide cash collateral, if requested by Bank, to be held
by Bank in an amount equal to one hundred percent (100%) of the maximum amount
of Bank's then outstanding obligations under L/Cs, or (ii) cause to be delivered
to Bank releases of all of Bank's then outstanding obligations under its
outstanding L/Cs.  Any cash collateral received by Bank pursuant to this Section
2.4(d) shall be held by Bank in an interest bearing account selected by Bank in
its reasonable credit judgment, and interest earned on deposits in such account,
if any, shall be for the account of the Borrower subject to the provisions of
this Agreement.  The provisions of this Section 2.4 shall survive the
termination of this Agreement with respect to any L/Cs then outstanding.


     .5  Facility Fee. Borrower shall pay to Bank a facility fee, (the "Facility
     ----------------
Fee"), on (i) March 31, for the fiscal quarter then ended, (ii) May 15, for the
fiscal quarter ended June 30, and (iii) August 15, for the fiscal quarter ended
September 30, and (iv) November 15 for the period from October 1 through the
Maturity Date (in each case, a "Facility Fee Payment Date"). The amount of the
Facility Fee (i) shall be due and payable on each of the above Facility Fee
Payment Dates, (ii) shall be calculated based upon Borrower's financial
statements for its fiscal quarter ended immediately prior to the Facility Fee
Payment Date as stated above, and (iii) shall equal the following percentages of
the product of the Revolving Commitment multiplied by the quotient of the actual
number of days in the measuring fiscal quarter divided by 365:

          (i)    0.15%, if, as of the applicable Test Date, the ratio of Net
                 Debt to EBITDA for the fiscal period then ended in less than
                 1.00:1.00;

          (ii)   0.25%, if, as of the applicable Test Date, the ratio of Net
                 Debt to EBITDA for the fiscal period then ended is greater than
                 or equal to 1.00:1.00 and less than 2.00:1.00; or

          (iii)  0.35%, if, as of the applicable Test Date, the ratio of Net
                 Debt to EBITDA for the fiscal period then ended is greater than
                 or equal to 2.00:1.00;

provided however, if Borrower fails to timely deliver the financial statements
- -------- -------                                                              
for the fiscal quarter then ended required to be delivered pursuant to
subsections 6.1(a) (i) and (ii), then the Facility Fee due for the succeeding
fiscal quarter, or other measuring period as the case may be, shall equal 0.35%
of the product of the Revolving Commitment multiplied by the quotient of the
actual number of days in the measuring fiscal quarter divided by 365.

                                  ARTICLE III
               GENERAL PROVISIONS CONCERNING THE REVOLVING LOANS

     .1  Use of Proceeds. The proceeds of the Revolving Loans hereunder shall be
     ------------------- 
used by Borrower and its Subsidiaries for their general working capital and
corporate purposes (including, without limitation, the financing of Permitted
Acquisitions), consistent with the terms and conditions hereof.

     .2  Computation of Interest and Fees.
     ------------------------------------ 

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

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

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

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

     .5  Reduced Return. If Bank shall have determined that any applicable law,
     ------------------ 
regulation, rule or regulatory requirement applicable to Bank (collectively in
this Section 3.5 "Requirement") regarding capital adequacy, or any change
                  -----------
therein, or any change in the interpretation or administration thereof by any
United States federal or state governmental authority, central bank or
comparable agency charged with the interpretation or administration thereof, or
compliance by Bank with any request or directive regarding capital

                                      -15-
<PAGE>
 
adequacy (whether or not having the force of law) of any such authority, central
bank or comparable agency, has or would have the effect of reducing the rate of
return on Bank's capital as a consequence of its Revolving Commitment and
obligations hereunder to a level below that which would have been achieved but
for such Requirement, change or compliance (taking into consideration Bank's
policies with respect to capital adequacy) by an amount deemed by Bank to be
material (which amount shall be determined by Bank's reasonable allocation of
the aggregate of such reductions resulting from such events), then from time to
time, within five Business Days after demand by Bank (including a calculation in
reasonable detail of such amount), Borrower shall pay to Bank such additional
amount or amounts as will compensate Bank for such reduction. Bank does not
currently have knowledge of any new Requirement or any pending change in any
existing Requirement that would result in such additional amounts being owed.

     .6  Indemnities and Losses.
     -------------------------- 

          (a)  Indemnities. Whether or not the transactions contemplated hereby
          ---------------- 
shall be consummated, Borrower agrees to indemnify, defend, and hold Bank, and
the shareholders, officers, directors, employees and agents of Bank (each, an
"Indemnified Person"), harmless from and against any and all claims,
- --------------------                                                
liabilities, losses, damages, costs and expenses (whether or not any of the
foregoing Indemnified Persons is a party to any litigation), including, without
limitation, reasonable attorneys fees and costs (including, without limitation,
the reasonable estimate of the allocated cost of in-house legal counsel and
staff) and costs of investigation, document production, attendance at a
deposition, or other discovery, prior to the assumption of defense by Borrower,
with respect to or arising out of any proposed acquisition by Borrower or any of
its Subsidiaries of any Person or any securities (including a self-tender), this
Agreement or any use of proceeds hereunder, or any claim, demand, action or
cause of action being asserted against Borrower or any of its Subsidiaries
(collectively, the "Indemnified Liabilities"), provided that Borrower shall have
                    -----------------------                                     
no obligation hereunder with respect to Indemnified Liabilities arising from the
gross negligence or willful misconduct of, or violations of this Agreement by,
any such Indemnified Persons.  If any claim is made, or any action, suit or
proceeding is brought, against any Indemnified Person of the type contemplated
by this Section, the Indemnified Person shall notify Borrower within thirty (30)
days of Bank being notified in writing of the commencement of such action, suit
or proceeding, and Borrower will assume the defense of such action, suit or
proceeding, employing counsel selected by Borrower and reasonably satisfactory
to the Indemnified Person, and pay the fees and expenses of such counsel.  This
covenant shall survive termination of this Agreement and payment of the
outstanding Note for a period of five years.

          (b)  Funding Losses. Borrower agrees to indemnify Bank and to hold
          ------------------- 
Bank harmless from any reasonable loss or expense including, but not limited to,
any such loss or expense arising from interest or fees payable by Bank to
lenders of funds obtained by it in order to maintain its Libor Rate Option
Revolving Loans hereunder, which Bank may sustain

                                      -16-
<PAGE>
 
or incur as a consequence of (i) payment, prepayment or conversion of any part
of any Rate Segment of the Libor Rate Portion on a day other than the last day
of the corresponding Rate Period (whether or not any such payment is pursuant to
demand by Bank under the Note and whether or not any such payment, prepayment or
conversion is consented to by Bank, unless Bank shall have expressly waived such
indemnity in writing); (ii) default by Borrower in making a conversion or
continuation after Borrower has given a notice thereof, (iii) default by
Borrower in making any payment after Borrower has given a notice of payment,
(iv) attempt by Borrower to revoke in whole or part any irrevocable notice given
pursuant to Section 2.3(e) hereof; or (v) breach of or default by any obligor in
the performance or observance of any covenant or condition in the Note, any
separate security, guarantee or suretyship agreement between Bank and any
obligor, or any other document executed and delivered to Bank by Borrower or any
of its Subsidiaries in connection with the indebtedness evidenced by the Note.
If Bank sustains any such loss or expense, it shall from time to time notify
Borrower of the amount reasonably determined in good faith by Bank (which
determination shall be conclusive) to be necessary to indemnify Bank for such
loss or expense. Such amount shall be due and payable by Borrower ON DEMAND
(provided that Bank shall give Borrower a written calculation of such amount in
reasonable detail). This covenant shall survive termination of this Agreement
and payment of the outstanding Note.

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

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

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

          (c) does or shall impose on Bank any other condition; and the result
of any of the foregoing is to increase the cost to Bank of making, renewing, or
maintaining its Revolving Commitment, or the Libor Rate Option Revolving Loans
or to reduce any amount receivable thereunder (which increase or reduction shall
be determined by Bank's reasonable allocation of the aggregate of such cost
increases or reduced amounts receivable resulting from such events), then, in
any such case, Borrower shall pay to Bank, within five Business Days of its
demand, any additional amounts necessary to compensate Bank for such additional
cost or reduced amount receivable as determined by Bank with respect to Sections
3.5 and 3.6 of this Agreement (provided that Bank shall give Borrower a written
calculation 

                                      -17-
<PAGE>
 
of reasonable detail of such amounts). If Bank becomes entitled to claim any
additional amounts pursuant to this subsection, it shall notify Borrower of the
event by reason of which it has become so entitled. Such notice shall contain a
statement incorporating the calculation as to any additional amounts payable
pursuant to the foregoing sentence, and such statement submitted by Bank to

<PAGE>
 
Agreement contains any known untrue statement of a material fact or omits to
state a known material fact (known to Borrower in the case of any document not

directive, or any waste or by-product thereof, at any real property or any other

any applicable statutes, regulations, ordinances or directives of any
governmental authority or court, which violations reasonably may result in
uninsured liability to Borrower or any Subsidiary or any of their respective
officers, employees, representatives, agents or shareholders in an uninsured
amount exceeding $5,000,000 for all such violations; and the unresolved
violations set forth in said Schedule 5.1(i) will not result in liability to
Borrower or any Subsidiary or any of their respective officers, employees,
representatives, agents or shareholders in an amount exceeding $5,000,000 for
all such unresolved violations. Except as set forth in said Schedule, no
employee or other person has made a claim or demand in writing against Borrower
or any Subsidiary based on alleged damage to health caused by any such hazardous
or toxic substance or by any waste or by-product thereof, other than claims,
demand or charges which have been settled or satisfied; and the unsatisfied
claims or demands against Borrower or any Subsidiary set forth in said Schedule
5.1(i) will not result in uninsured liability to Borrower or any Subsidiary or
any of their respective officers, employees, representatives, agents or
shareholders in an amount exceeding $5,000,000 in excess of reserves on the
books of Borrower for all such unsatisfied claims or demands. Except as set

          --------------------- 
existence or threatened involving Borrower or any of its Subsidiaries that may
materially adversely affect the consolidated financial condition or operations
of Borrower and its

                                      -22-
<PAGE>
 
Subsidiaries taken as a whole or that reasonably could be expected to result in
a Material Adverse Change.

Solvent.

          (l)  Title to Properties. Borrower and each of its Subsidiaries has

material properties and assets subject to no liens, mortgages, pledges, security
interests, encumbrances or charges of any kind, except those as are permitted
under Section 6.2(d) hereof.

          (m)  Tax Returns. To the best of Borrower's and each of its
          ---------------- 
Subsidiary's knowledge, after due inquiry, except as set forth on Schedule
                                                                  --------
5.1(m) hereto and, from and after the Closing Date, where the failure of
- -------
Borrower or any of its Subsidiaries to file or to cause the filing of any tax
return, report, or declaration shall not result in a Material Adverse Change,
Borrower and each of its Subsidiaries, have filed, or caused to be filed, in a
timely manner all tax returns, reports and declarations which are required to be
filed by each of them (including any automatic or granted extensions). All
information in such tax returns, reports and declarations is complete and
accurate in all material respects. Borrower and each of its Subsidiaries has
paid or caused to be paid all taxes due and payable or claimed due and payable
in any assessment received by it, except taxes the validity of which are being
contested in good faith by appropriate proceedings diligently pursued and
available to Borrower or its Subsidiaries and with respect to which adequate
reserves have been set aside on its books. Adequate provision has been made for
the payment of all accrued and unpaid Federal, State, county, local, foreign and
other taxes whether or not yet due and payable and whether or not disputed.

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

          (o)  Year 2000 Compliance. Any reprogramming required to address the
          ------------------------- 
Year 2000 problem (i.e., the inability of certain computer applications to
recognize correctly and perform properly date-sensitive functions involving
certain dates prior to and any date after December 31, 1999), of (a) the
Borrower's and its Subsidiaries' critical or material computer systems and (b)
critical or material equipment containing embedded microchips (including, to the
best of Borrower's knowledge, systems and equipment supplied by others or with
which the Borrower's or its Subsidiaries' systems interface) and the testing of
all such systems and equipment, as so reprogrammed, will be completed by October
30, 1999.

                                      -23-
<PAGE>
 
The cost to the Borrower and its Subsidiaries of such reprogramming and testing
and of the reasonably foreseeable consequences of the Year 2000 problem to the
Borrower and its Subsidiaries (including, without limitation, reprogramming
errors and the failure of others' systems and equipment) will not result in an
Event of Default or cause a Material Adverse Change.

satisfactory condition as of when possession was taken.  Tenant further
acknowledges that no representations as to the repair of the premises, nor
promises to alter, remodel of improve the premises have been made by Landlord,
unless such are expressly set forth in this lease.  If this lease is executed
before the premises become vacant or otherwise available and ready for
occupancy, or if any present tenant or occupant of the premises holds over and
Landlord cannot, using good faith efforts, acquire possession of the premises
prior to the date above recited as the commencement date of this lease, Landlord
shall not be deemed to be in default hereunder, nor in any way liable to Tenant
because of such failure. and Tenant agrees to accept possession of the premises
at such time as Landlord is able to tender the same, which date shall
thenceforth be deemed the "commencement date"; and the term of this tease shall
automatically be extended so as to include the full number of months

                                                             Dollars ($       
- ------------------------------------------------------------          ---------
         ) per month, in advance, except that the monthly installment which

otherwise shall be due on the commencement date recited above, shall be due and
payable on the date hereof. Thereafter, one such monthly installment shall be
due and payable without demand on or before the first day of each calendar month
succeeding the commencement date recited above during the demised term; further
provided, that the rental payment for any fractional calendar month at the
commencement or end of the lease term shall be prorated.

interest, as security for the full, timely and faithful performance of Tenant's
covenants and obligations under this lease, it being expressly understood and
agreed that such deposit is not an advance rental deposit or a measure of
Landlord's damages in case of Tenant's default.  Upon the occurrence of any
event of default by Tenant, Landlord may, from time to time, without prejudice
to any other remedy provided herein or provided by law, use such fund to the
extent necessary to make good any arrears of rent or other payments due Landlord
hereunder, and any other damage, injury, expense or liability caused by any
event of Tenant's default; and Tenant shall pay to Landlord on demand the amount
so applied in order to restore the security deposit to its original amount.
Although the security deposit shall be deemed the property of Landlord, any
remaining balance of such deposit shall be returned by Landlord to Tenant at

laws, ordinances and regulations, the premises must be altered to lawfully
accommodate Tenant's use and occupancy thereof, such alterations shall be made
only with the consent of Landlord, but the entire cost thereof shall be borne by
Tenant; provided, that, the necessity of Landlord's consent shall in no way
create any liability against Landlord for failure of Tenant to comply. or alter
the premises to comply, with such laws. ordinances and regulations.  Tenant
shall not permit any objectionable or unpleasant odors, smoke, dust, gas, noise
or vibrations to emanate from the premises, nor take any other action which

cost and expense thereof unless Landlord in its sole discretion determines that
such cost and expense is properly allocable in another proportion or solely to
either Tenant or the other tenants occupying said building. Tenant shall pay to
Landlord its share, determined as aforesaid, of such costs and expenses, upon
demand, as additional rent, in the event Landlord elects to perform or cause to
be performed such work.

     D. Landlord shall have the right to coordinate any repairs and other
maintenance of any rail tracks serving or to serve the building, and if Tenant
uses such rail tracks, Tenant shall reimburse Landlord or the railroad company
from time to time upon demand, as additional rent, for a share of the costs of
such repairs and maintenance and any other sums specified in any agreement to
which Landlord or Tenant is a party respecting such tracks, such costs to be
borne proportionately by all tenants in the building of which the premises are a
part using such rail tracks, based upon the actual number of rail cars shipped
and received by each tenant during each calendar year in which the lease term
falls.

     E. Tenant shall, at its own cost and expense, enter into a regularly
scheduled preventive maintenance/service contract with a maintenance contractor
approved by Landlord, for servicing all heating and air conditioning systems and
equipment within the premises. The service contract must include all services
suggested by the equipment manufacturer within the operation/maintenance manual
and must become effective within thirty (30) days of the date Tenant takes
possession of the premises.

     F. Tenant shall, at its own cost and expense, repair any damage to the
premises resulting from and/or caused in whole or in part by the negligence or
misconduct of Tenant, its agents, servants, employees, patrons, customers, or
any other person entering upon the premises as a result of Tenant's business
activities or caused by Tenant's default hereunder.

     7. Alterations.  Tenant shall not make any alterations, additions or
improvements to the premises (including, without limitation, the roof and wall
penetrations) without the prior written consent of Landlord, which consent may
in Landlord's sole discretion be withheld.  Tenant may, without the consent of
Landlord, but at its own cost and expense and in a good workmanlike manner,
erect such shelves, bins, machinery and other trade fixtures as it may deem
advisable, without altering the basic character of the building or improvements
and without overloading or damaging such building or improvements, and in each
case after complying with all applicable governmental laws, ordinances,
regulations and other requirements.  All alterations, additions, improvements
and partitions erected by Tenant shall be and remain the property of Tenant
during

                                       5
<PAGE>
 
the term of this lease and Tenant shall, unless Landlord otherwise elects
as hereinafter provided, remove all alterations, additions, improvements and
partitions erected by Tenant and restore the premises to their original
condition by the date of termination of this lease or upon earlier vacating of
the premises; provided, however, that if at such time Landlord so elects such
alterations, additions, improvements and partitions shall become the property of
Landlord as of the date of termination of this lease or upon earlier vacating of
the premises, and title shall pass to Landlord under this lease as by a bill of
sale.  All shelves, bins, machinery and trade fixtures installed by Tenant may
be removed by Tenant prior to the termination of this lease if Tenant so elects,
and shall be removed by the date of termination of this lease or upon earlier
vacating of the premises it required by Landlord; upon any such removal Tenant
shall restore the premises to their original condition.  All such removals and
restoration shall be accomplished in a good workmanlike manner so as not to
damage the primary structure or structural qualities of the buildings and other
improvements within which the premises are situated.  If Landlord shall, in its
sole discretion, consent to any alterations, additions or improvements proposed
by Tenant, Tenant shall construct the same in accordance with all governmental
laws, ordinances, rules and regulations and shall, prior to construction,
provide such assurances to Landlord, (including but not limited to, waivers of
lien, surety company performance bonds and personal guaranties of individuals of
substance) as Landlord shall require to protect Landlord against any loss from
any mechanics', laborers' or materialmen's liens, or other liens.

     8. Signs.  Tenant shall not install any signs upon the exterior of said
buildings, except that Landlord will provide, at Tenant's request and cost,
Landlord's standard identification sign, which sign shall be removed by Tenant
upon termination of this lease.

     9. Inspections.  Landlord and Landlord's agents and representatives shall
have the right to enter and inspect the premises at any reasonable time during
business hours, for the following purposes: (i) to ascertain the condition of
the premises; (ii) to determine whether Tenant is diligently fulfilling Tenant's
responsibilities under this lease; (iii) to make such repairs as may be required
or permitted to be made by Landlord under the terms of this lease; or (iv) to do
any other act or thing which Landlord deems reasonable to preserve the premises
and the building and improvements of which the premises are a part. During the
period that is six (6) months prior to the end of the term hereof and at any
time Tenant is in default hereunder and such default has remained uncured for at
least thirty (30) days, Landlord and Landlord's agents and representatives shall
have the right to enter the premises at any reasonable time during business
hours for the purpose of showing the premises and shall have the right to erect
on the premises suitable signs indicating that the premises are available for
lease. Tenant shall give written notice to Landlord at least thirty (30) days
prior to vacating the premises and shall arrange to meet with Landlord for a
joint inspection of the premises prior to vacating. In the event of Tenant's
failure to give such notice or arrange such joint inspection, Landlord's
inspection at or after Tenant's vacating the premises shall be conclusively
deemed correct for purposes of determining Tenant's responsibility for repairs
and restoration.

     10. Utilities.  Landlord agrees to provide, at its cost, water, electricity
and telephone service connections into the premises; but Tenant shall pay for
all water, gas, heat, light, power, telephone, sewer, sprinkler system charges
and other utilities and services used on or from the premises, including without
limitation, Tenant's proportionate share as determined by Landlord of any
central station signaling system installed in the premises or the building of
which the

                                       6
<PAGE>
 
premises are a part, together with any taxes, penalties, and surcharges or the
like pertaining thereto and any maintenance charges for utilities. Tenant shall
furnish all electric light bulbs, tubes and ballasts. If any such services are
not separately metered to Tenant, Tenant shall pay such proportion of all
charges jointly metered with other premises as determined by Landlord, in its
sole discretion, to be reasonable. Any such charges paid by Landlord and
assessed against Tenant shall be immediately payable to Landlord on demand and
shall be additional rent hereunder. Landlord shall in no event be liable for any
interruption or failure of utility services on or to the premises.

     11. Assignment and Subletting.

     A. Tenant shall not have the right to assign or pledge this lease or to
sublet the whole or any part of the premises, whether voluntarily or by
operation of law, or permit the use or occupancy of the premises by anyone other
than Tenant, without the prior written consent of Landlord, and such
restrictions shall be binding upon any assignee or subtenant to which Landlord
has consented. In the event Tenant desires to sublet the premises, or any
portion thereof, or assign this lease, Tenant shall give written notice thereof
to Landlord within a reasonable time prior to the proposed commencement date of
such subletting or assignment, which notice shall set forth the name of the
proposed subtenant or assignee, the relevant terms of any sublease and copies of
financial reports and other relevant financial information of the proposed
subtenant or assignee. Notwithstanding any permitted assignment or subletting,
Tenant shall at all times remain directly, primarily and fully responsible and
liable for the payment of the rent herein specified and for compliance with all
of its other obligations under the terms, provisions and covenants of this
lease. Upon the occurrence of an "event of default" (as hereinafter defined), if
the premises or any part thereof are then assigned or sublet, Landlord, in
addition to any other remedies herein provided, or provided by law, may, at its
option collect directly from such assignee or subtenant all rents due and
becoming due to Tenant under such assignment or sublease and apply such rent
against any sums due to Landlord from Tenant hereunder, and no such collection
shall be construed to constitute a novation or a release of Tenant from the
further performance of Tenant's obligations hereunder.

     B. In addition to, but not in limitation of, Landlord's right to approve of
any subtenant or assignee, Landlord shall have the option, in its sole
discretion, in the event of any proposed subletting or assignment, to terminate
this lease, or in the case of a proposed subletting of less than the entire
premises, to recapture the portion of the premises to be sublet, as of the date
the subletting or assignment is to be effective. The option shall be exercised,
if at all, by Landlord giving Tenant written notice thereof within sixty (60)
days following Landlord's receipt of Tenant's written notice as required above.
If this lease shall be terminated with respect to the entire demised premises
pursuant to this paragraph, the term of this lease shall end on the date stated
in Tenant's notice as the effective date of the sublease or assignment as if
that date had been originally fixed in this lease for the expiration of the term
hereof; provided, however, that effective on such date Tenant shall pay Landlord
all amounts, as estimated by Landlord, payable by Tenant to such date, with
respect to taxes, insurance, repairs, maintenance, restoration and other
obligations, costs or charges which are the responsibility of Tenant hereunder.
Further, upon any such cancellation Landlord and Tenant shall have no further
obligations or liabilities to each other under this lease, except with respect
to obligations or liabilities which accrued hereunder as of such cancellation
date (in the same manner as if such cancellation date were the date originally
fixed in this lease for the expiration of the term hereof). If Landlord
recaptures

                                       7
<PAGE>
 
under this paragraph only a portion of the demised premises, the rent
during the unexpired term hereof shall abate proportionately based on the rent
per square foot contained in this lease as of the date immediately prior to such
recapture.  Tenant shall, at Tenant's own cost and expense, discharge in full
any outstanding commission obligation on the part of Landlord with respect to
this lease, and any commissions which may be due and owing as a result of any
proposed assignment or subletting, whether or not the premises are recaptured
pursuant hereto and rented by Landlord to the proposed tenant or any other
tenant.

     C. Notwithstanding the provisions of the foregoing paragraphs, Tenant may,
without Landlord's consent, assign this lease to any corporation succeeding to
substantially all the business and assets of Tenant by merger, consolidation,
purchase of assets or otherwise or to any corporation or entity which is a
subsidiary or division of Tenant, provided that the following conditions are
satisfied: (i) the total assets and net worth of such assignee shall be equal to
or more than that of Tenant immediately prior to such transaction; (ii) Tenant
is not then in default hereunder; and (iii) such successor shall execute and
deliver to Landlord an instrument in writing fully assuming all the obligations
and liabilities imposed upon Tenant hereunder.  Upon satisfaction of the
foregoing, Landlord agrees to discharge Tenant from any further liability
hereunder.

     D. If Tenant is a corporation, the shares of which at the time of execution
of this lease, are held by fewer than fifty (50) persons, and if at any time
during the term of this lease persons, firms or corporations who own at least
one-third (1/3) of its shares at the time of the execution of this lease, or
following Landlord's consent to a transfer of such shares, cease to own such
shares (other than as a result of transfer by bequest or inheritance) and such
transfer shall not first have been approved in writing by Landlord, such
transfer shall, at the option of Landlord, be deemed a default by Tenant under
this lease and Landlord shall have all the rights and remedies granted to it
hereunder and by law in case of defaults. Tenant may transfer stock under the
terms of this lease to members of the immediate family of shareholders of the
parent corporation.

     12. Fire and Casualty Damage.

     A. Landlord agrees to maintain standard fire and extended coverage
insurance covering the building of which the premises are a part in an amount
not less than ninety percent (90%) (or such greater percentage as may be
necessary to comply with the provisions of any co-insurance clauses of the
policy) of the "replacement cost" thereof as such term is defined in the
Replacement Cost Endorsement to be attached thereto, insuring against the perils
of fire and lightning and including extended coverage, or at Landlord's option
all risk coverage, such coverages and endorsements to be as defined, provided
and limited in the standard bureau forms prescribed by the insurance regulatory
authority for the state in which the premises are situated for use by insurance
companies admitted in such state for the writing of such insurance on risks
located within such state. Subject to the provisions of subparagraphs 12C, 12D
and 12F below, such insurance shall be for the sole benefit of Landlord and
under its sole control. If during the second full lease year after the
commencement date of this lease, or during any subsequent year of the primary
term or any renewal or extension, Landlord's cost of maintaining such insurance
shall exceed Landlord's cost of maintaining such insurance for the first full
lease year of the term hereof, Tenant agrees to pay to Landlord, as additional
rental, Tenant's full proportionate share (as defined in subparagraph 24J) of
such excess. Said payments shall be made to Landlord within ten (10) days after
presentation to Tenant of Landlord's statement setting forth the amount

                                       8
<PAGE>
 
due, and the failure to pay such excess shall be treated in the same manner as a
default in the payment of rent hereunder when due. Any payment to be made
pursuant to this subparagraph 12A with respect to the year in which this lease
commences or terminates shall bear the same ratio to the payment which would be
required to be made for the full year as the part of such year covered by the
term of this lease bears to a full year. Tenant shall not take out separate
insurance concurrent in form or contributing in the event of loss with that
required to be maintained by Landlord hereunder unless Landlord is included as
an additional insured thereon. Tenant shall immediately notify Landlord whenever
any such separate insurance is taken out and shall promptly deliver to Landlord
the policy or policies of such insurance.

     B. If the buildings situated upon the premises should be damaged or
destroyed by fire, tornado or other casualty, Tenant shall give immediate
written notice thereof to Landlord.

     C. If the buildings situated upon the premises should be damaged by any
peril covered by the insurance to be provided by Landlord under subparagraph 12A
above, but only to such extent that rebuilding or repairs can in Landlord's
estimation be completed within one hundred fifty (150) days after the date upon
which Landlord is notified by Tenant of such damage, (except that Landlord may
elect not to rebuild if such damage occurs during the last year of the term
hereof), this lease shall not terminate, and Landlord shall at its sole cost and
expense thereupon proceed with reasonable diligence to rebuild and repair such
buildings to substantially the condition in which they existed prior to such
damage, except Landlord shall not be required to rebuild, repair or replace any
part of the partitions, fixtures, additions and other improvements which may
have been placed in, on or about the premises by Tenant. If the premises are
untenantable in whole or in part following such damage, the rent payable
hereunder during the period in which the premises are untenantable shall be
reduced to such extent as may be fair and reasonable under all of the
circumstances. In the event that Landlord should fail to complete such repairs
and rebuilding within one hundred fifty (150) days after the date upon which
Landlord is notified by Tenant of such damage, Tenant may at its option
terminate this lease by delivering written notice of termination to Landlord as
Tenant's exclusive remedy, whereupon all rights and obligations hereunder shall
cease and terminate; provided, however, that if construction is delayed because
of changes, deletions, or additions in construction requested by Tenant,
strikes, lockouts, casualties, acts of God, war, material or labor shortages,
Governmental regulation or control or other causes beyond the reasonable control
of Landlord, the period for restoration, repair or rebuilding shall be extended
for the amount of time Landlord is so delayed.

     D. If the buildings situated upon the premises should be damaged or
destroyed by fire, tornado or other casualty and Landlord is not required to
rebuild pursuant to the provisions of subparagraph 12C hereof, this lease shall
at the option of Landlord, upon notice to Tenant, given within thirty (30) days
after Landlord is notified by Tenant of such damage, terminate and the rent
shall be abated during the unexpired portion of this lease, effective upon the
date of the occurrence of such damage.

     E. Tenant covenants and agrees to maintain insurance on all alterations,
additions, partitions and improvements erected by or on behalf of Tenant in, on
or about the premises in an amount not less than ninety percent (90%) (or such
greater percentage as may be necessary to comply with the provisions of any co-
insurance clause of the policy) of the "replacement cost" thereof, as such term
is defined in the Replacement Cost Endorsement to be attached thereto.  Such

                                       9
<PAGE>
 
insurance shall insure against the perils and be in form, including stipulated
endorsements, as provided in subparagraph 12A hereof.  Such insurance shall be
for the sole benefit of Tenant and under its sole control provided that Tenant
shall be obligated to immediately commence the rebuilding of the improvements
erected by Tenant and to apply such proceeds in payment of the cost thereof.
All such policies shall be procured by Tenant from responsible insurance
companies satisfactory to Landlord.  Certified copies of policies of such
insurance, together with receipt evidencing payment of the premiums therefor,
shall be delivered to Landlord prior to the commencement date of this lease.
Not less than fifteen (15) days prior to the expiration date of any such
policies, certified copies of renewals thereof (bearing notations evidencing the
payment of renewal premiums) shall be delivered to Landlord.  Such policies
shall further provide that not less than thirty (30) days written notice shall
be given to Landlord before such policy may be cancelled or changed to reduce
insurance provided thereby.

     F. Notwithstanding anything herein to the contrary, in the event the holder
of any indebtedness secured by a mortgage or deed of trust covering the premises
or the building of which the premises are a part requires that the insurance
proceeds be applied to such indebtedness, then Landlord shall have the right to
terminate this lease by delivering written notice of termination to Tenant
within fifteen (15) days after such requirement is made by any such holder,
whereupon all rights and obligations hereunder shall cease and terminate.

     G. Each of Landlord and Tenant hereby releases the other from any and all
liability or responsibility to the other or anyone claiming through or under
them by way of subrogation or otherwise for any loss or damage to property
caused by fire or any other perils insured in policies of insurance covering
such property, even if such loss or damage shall have been caused by the fault
or negligence of the other party, or anyone for whom such party may be
responsible, including any other tenants or occupants of the remainder of the
building in which the premises are located; provided, however, that this release
shall be applicable and in force and effect only to the extent that such release
shall be lawful at that time and in any event only with respect to loss or
damage occurring during such times as the releasor's policies shall contain a
clause or endorsement to the effect that any such release shall not adversely
affect or impair said policies or prejudice the right of the releasor to recover
thereunder and then only to the extent of the insurance proceeds payable under
such policies. Each of Landlord and Tenant agrees that it will request its
insurance carriers to include in its policies such a clause or endorsement.  If
extra cost shall be charged therefor, each party shall advise the other thereof
and of the amount of the extra cost, and the other party, at its election, may
pay the same, but shall not be obligated to do so.  If such other party fails to
pay such extra cost, the release provisions of this paragraph shall be
inoperative against such other party to the extent necessary to avoid
invalidation of such releasor's insurance.

     H. In the event of any damage or destruction to the premises by any peril
covered by the provisions of this Paragraph 12, Tenant shall, upon notice from
Landlord, forthwith remove, at its sole cost and expense, such portion or all of
Tenant's shelves, bins, machinery and other trade fixtures and all other
property belonging to Tenant or his licensees from such portion or all of the
premises as Landlord shall request and Tenant hereby indemnifies and holds
harmless the property.  Landlord (including without limitation the trustee and
beneficiaries if Landlord is a trust).  Landlord's agents and employees from any
loss, liability, claims, suits, costs, expenses, including attorney's fees and
damages, both real and alleged, arising out of any damage or injury

                                       10
<PAGE>
 
as a result of the failure to properly secure the premises prior to such removal
and/or as a result of such removal.

     13. Liability.  Landlord shall not be liable to Tenant or Tenant's
employees, agents, patrons or visitors, or to any other person whomsoever, for
any injury to person or damage to property on or about the premises, resulting
from and/or caused in part or whole by the negligence or misconduct of Tenant,
its agents, servants or employees, or of any other person entering upon the
premises, or caused by the buildings and improvements located on the promises
becoming out of repair, or caused by leakage of gas, oil, water or steam or by
electricity emanating from the premises, or due to any cause whatsoever, and
Tenant hereby covenants and agrees that it will at all times indemnify and hold
safe and harmless the property, the Landlord (including without limitation the
trustee and beneficiaries if Landlord is a trust), Landlord's agents and
employees from any loss, liability, claims, suits, costs, expenses, including
attorney's fees and damages, both real and alleged, arising out of any such
damage or injury; except injury to persons or damage to property the sole cause
of which is the negligence of Landlord or the failure of Landlord to repair any
part of the premises which Landlord is obligated to repair and maintain
hereunder within a reasonable time after the receipt of written notice from
Tenant of needed repairs. Tenant shall procure and maintain throughout the term
of this lease a policy or policies of insurance, in form and substance
satisfactory to Landlord, at Tenant's sole cost and expense, insuring both
Landlord (and if Landlord is a trust, the trustee, beneficiaries and their
agents) and Tenant against all claims, demands or actions arising out of or in
connection with: (i) the premises; (ii) the condition of the premises; (iii)
Tenant's operations in and maintenance and use of the premises; and (iv)
Tenant's liability assumed under this lease; the limits of such policy or
policies to be in the amount of not less than $2,000,000 per occurrence in
respect of injury to persons (including death), and in the amount of not less
than $250,000 per occurrence in respect of property damage or destruction,
including loss of use thereof. All such policies shall be procured by Tenant
from responsible insurance companies satisfactory to Landlord. Certified copies
of such policies, together with receipt evidencing payment of premiums therefor,
shall be delivered to Landlord prior to the commencement date of this lease. Not
less than fifteen (15) days prior to the expiration date of any such policies,
certified copies of the renewals thereof (bearing notations evidencing the
payment of renewal premiums) shall be delivered to Landlord. Such policies shall
further provide that not less than thirty (30) days written notice shall be
given to Landlord before such policy may be cancelled or changed to reduce the
insurance coverage provided thereby.

     14.  Condemnation.

     A. If the whole or any substantial part of the premises should be taken for
any public or quasi-public use under governmental law, ordinance or regulation,
or by right of eminent domain, or by private purchase in lieu thereof and the
taking would prevent or materially interfere with the use of the premises for
the purpose for which they are then being used, this lease shall terminate and
the rent shall be abated during the unexpired portion of this lease, effective
when the physical taking of said premises shall occur.

     B. If part of the premises shall be taken for any public or quasi-public
use under any governmental law, ordinance or regulation, or by right of eminent
domain, or by private purchase in lieu thereof, and this lease is not terminated
as provided in the subparagraph above, this lease shall not terminate but the
rent payable hereunder during the unexpired portion of this lease shall

                                       11
<PAGE>
 
be reduced to such extent as may be fair and reasonable under all of the
circumstances and Landlord shall undertake to restore the premises to a
condition suitable for Tenant's use, as near to the condition thereof
immediately prior to such taking as is reasonably feasible under all the
circumstances.

     C. In the event of any such taking or private purchase in lieu thereof,
Landlord and Tenant shall each be entitled to receive and retain such separate
awards and/or portion of lump sum awards as may be allocated to their respective
interests in any condemnation proceedings; provided that Tenant shall not be
entitled to receive any award for Tenant's loss of its leasehold interest, the
right to such award being hereby assigned by Tenant to Landlord.

     15. Holding Over. Tenant will, at the termination of this lease by lapse of
time or otherwise, yield up immediate possession to Landlord.  If Tenant retains
possession of the premises or any part thereof after such termination, then
Landlord may, at its option, serve written notice upon Tenant that such holding
over constitutes any one of (i) creation of a month to month tenancy, upon the
terms and conditions set forth in this lease, or (ii) creation of a tenancy at
sufferance, in any case upon the terms and conditions set forth in this lease;
provided, however, that the monthly rental (or daily rental under (ii)) shall,
in addition to all other sums which are to be paid by Tenant hereunder, whether
or not as additional rent, be equal to double the rental being paid monthly to
Landlord under this lease immediately prior to such termination (prorated in the
case of (ii) on the basis of a 365 day year for each day Tenant remains in
possession). If no such notice is served, then a tenancy at sufferance shall be
deemed to be created at the rent in the preceding sentence.  Tenant shall also
pay to Landlord all damages sustained by Landlord resulting from retention of
possession by Tenant, including the loss of any proposed subsequent tenant for
any portion of the premises.  The provisions of this paragraph shall not
constitute a waiver by Landlord of any right of re-entry as herein set forth;
nor shall receipt of any rent or any other act in apparent affirmance of the
tenancy operate as a waiver of the right to terminate this lease for a breach of
any of the terms, covenants, or obligations herein on Tenant's part to be
performed.

     16. Quiet Enjoyment. Landlord covenants that it now has, or will acquire
before Tenant takes possession of the premises, good title to the premises, free
and clear of all liens and encumbrances, excepting only the lien for current
taxes not yet due, such mortgage or mortgages as are permitted by the terms of
this lease, zoning ordinances and other building and fire ordinances and
governmental regulations relating to the use of such property, and easements,
restrictions and other conditions of record. In the event this lease is a
sublease, then Tenant agrees to take the premises subject to the provisions of
the prior leases. Landlord represents and warrants that it has full right and
authority to enter into this lease and that Tenant, upon paying the rental
herein set forth and performing its other covenants and agreements herein set
forth, shall peaceably and quietly have, hold and enjoy the premises for the
term hereof without hindrance or molestation from Landlord, subject to the terms
and provisions of this lease. Landlord agrees to make reasonable efforts to
protect Tenant from interference or disturbance by other tenants or third
persons; however, Landlord shall not be liable for any such interference or
disturbance, nor shall Tenant be released from any of the obligations of this
lease because of such interference or disturbance.

                                       12
<PAGE>
 
     17. Events of Default. The following events shall be deemed to be events of
default by Tenant under this lease:
          (a) Tenant shall fail to pay when or before due any sum of money
     becoming due to be paid to Landlord hereunder, whether such sum be any
     installment of the rent herein reserved, any other amount treated as
     additional rent hereunder, or any other payment or reimbursement to
     Landlord required herein, whether or not treated as additional rent
     hereunder, and such failure shall continue for a period of five (5) days
     from the date such payment was due; or

          (b) Tenant shall fail to comply with any term, provision or covenant
     of this lease other than by failing to pay when of before due any sum of
     money becoming due to be paid to Landlord hereunder, and shall not cure
     such failure within twenty (20) days (forthwith, if the default involves a
     hazardous condition) after written notice thereof to Tenant; or

          (c) Tenant shall abandon or vacate any substantial portion of the
     premises; or

          (d) Tenant shall fail to immediately vacate the premises upon
     termination of this lease, by lapse of time or otherwise, or upon
     termination of Tenant's right to possession only; or

          (e) The leasehold interest of Tenant shall be levied upon under
     execution or be attached by process of law or Tenant shall fail to contest
     diligently the validity of any lien or claimed lien and give sufficient
     security to Landlord to insure payment thereof or shall fail to satisfy any
     judgment rendered thereon and have the same released, and such default
     shall continue for ten (10) days after written notice thereof to Tenant; or

          (f) Tenant shall become insolvent, admit in writing its inability to
     pay its debts generally as they become due, file a petition in bankruptcy
     or a petition to take advantage of any insolvency statute, make an
     assignment for the benefit of creditors, make a transfer in fraud of
     creditors, apply for or consent to the appointment of a receiver of itself
     or of the whole or any substantial part of its property, or file a petition
     or answer seeking reorganization or arrangement under the federal
     bankruptcy laws, as now in effect or hereafter amended, or any other
     applicable law or statute of the United States or any state thereof; or

          (g) A court of competent jurisdiction shall enter an order, judgment
     or decree adjudicating Tenant a bankrupt, or appointing a receiver of
     Tenant, or of the whole or any substantial part of its property, without
     the consent of Tenant, or approving a petition filed against Tenant seeking
     reorganization or arrangement of Tenant under the bankruptcy laws of the
     United States, as now in effect or hereafter amended, or any state thereof,
     and such order, judgment or decree shall not be vacated or set aside or
     stayed within thirty (30) days from the date of entry thereof.

     18. Remedies. Upon the occurrence of any of such events of default
described in Paragraph 17 hereof or elsewhere in this lease, Landlord shall have
the option to pursue any one or more of the following remedies without any
notice or demand whatsoever:

          (a) Landlord may, at its election, terminate this lease or terminate
     Tenant's right to possession only, without terminating the lease;
     

                                       13
<PAGE>
 
          (b) Upon any termination of this lease, whether by lapse of time or
     otherwise, or upon any termination of Tenant's right to possession without
     termination of the lease, Tenant shall surrender possession and vacate the
     premises immediately, and deliver possession thereof to Landlord, and
     Tenant hereby grants to Landlord full and free license to enter into and
     upon the premises in such event with or without process of law and to
     repossess Landlord of the premises as of Landlord's former estate and to
     expel or remove Tenant and any others who may be occupying or within the
     premises and to remove any and all property therefrom without being deemed
     in any manner guilty of trespass, eviction or forcible entry or detainer,
     and without incurring any liability for any damage resulting therefrom,
     Tenant hereby waiving any right to claim damage for such re-entry and
     expulsion, and without relinquishing Landlord's right to rent or any other
     right given to Landlord hereunder or by operation of law ;

          (c) Upon any termination of this lease, whether by lapse of time or
     otherwise, Landlord shall be entitled to recover as damages, all rent,
     including any amounts treated as additional rent hereunder, and other sums
     due and payable by Tenant on the date of termination, plus the sum of (i)
     an amount equal to the then present value of the rent, including any
     amounts treated as additional rent hereunder, and other sums provided
     herein to be paid by Tenant for the residue of the stated term hereof, less
     the fair rental value of the premises for such residue (taking into account
     the time and expense necessary to obtain a replacement tenant or tenants,
     including expenses hereinafter described in subparagraph (d) relating to
     recovery of the premises, preparation for relettling and for reletting
     itself), and (ii) the cost of performing any other covenants which would
     have otherwise been performed by Tenant .

          (d) (i)  Upon any termination of Tenant's right to possession only
     without termination of the lease, Landlord may, at Landlord's option, enter
     into the premises, remove Tenant's signs and other evidences of tenancy,
     and take and hold possession thereof as provided in subparagraph (b) above,
     without such entry and possession terminating the lease or releasing
     Tenant, in whole or in part, from any obligation, including Tenant's
     obligation to pay the rent, including any amounts treated as additional
     rent, hereunder for the full term. In any such case Tenant shall pay
     forthwith to Landlord, if Landlord so elects, a sum equal to the entire
     amount of the rent, including any amounts treated as additional rent
     hereunder, for the residue of the stated term hereof plus any other sums
     provided herein to be paid by Tenant for the remainder of the lease term.

              (ii)  Landlord may, but need not, relet the premises or any part
     thereof for such rent and upon such terms as Landlord in its sole
     discretion shall determine (including the right to relet the premises for a
     greater or lesser term than that remaining under this lease, the right to
     relet the premises as a part of a larger area, and the right to change the
     character or use made of the premises) and Landlord shall not be required
     to accept any tenant offered by Tenant or to observe any instructions given
     by Tenant about such reletting. In any such case, Landlord may make
     repairs, alterations and additions in or to the premises, and redecorate
     the same to the extent Landlord deems necessary or desirable, and Tenant
     shall, upon demand, pay the cost thereof, together with Landlord's expenses
     of retelling, including, without limitation, any broker's commission
     incurred by Landlord. If the consideration collected by Landlord upon any
     such reletting plus any sums previously collected front Tenant are not
     sufficient to pay the full amount of all rent, including any

                                       14
<PAGE>
 
     amounts treated as additional rent hereunder and other sums reserved in
     this lease for the remaining term hereof, together with the costs of
     repairs, alterations, additions, redecorating, and Lessor's expenses of
     reletting and the collection of the rent accruing therefrom (including
     attorney's tees and broker's commissions), Tenant shall pay to Landlord the
     amount of such deficiency upon demand and Tenant agrees that Landlord may
     file suit to recover any sums falling due under this section from time to
     time;

          (e) Landlord may, at Landlord's option, enter into and upon the
     premises, with or without process of law, it Landlord determines in its
     sole discretion that Tenant is not acting within a commercially reasonable
     time to maintain, repair or replace anything for which Tenant is
     responsible hereunder and correct the same, without being deemed in my
     manner guilty of trespass, eviction or forcible entry and detainer and
     without incurring any liability for any damage resulting therefrom and
     Tenant agrees to reimburse Landlord, on demand, as additional rent, for any
     expenses which Landlord may incur in thus effecting compliance with
     Tenant's obligations under this lease;

          (f) Any and all property which may be removed from the premises
     by Landlord pursuant to the authority of the lease or of law, to which
     Tenant is or may be entitled, may be handled, removed and stored, as the
     case may be, by or at the direction of Landlord at the risk, cost and
     expense of Tenant, and Landlord shall in no event be responsible for the
     value, preservation or safekeeping thereof. Tenant shall pay to Landlord,
     upon demand, any and all expenses incurred in such removal and all storage
     charges against such property so long as the same shall be in Landlord's
     possession or under Landlord's control. Any such property of Tenant not
     retaken by Tenant from storage within thirty (30) days after removal from
     the premises shall conclusively be presumed to have been conveyed by Tenant
     to Landlord under this lease as a bill of sale without further payment or
     credit by Landlord to Tenant.

     In the event Tenant fails to pay any installment of rent, including any
amount treated as additional rent hereunder, or other sums hereunder as and when
such installment or other charge is due, Tenant shall pay to Landlord on demand
a late charge in an amount equal to five percent (5%) of such installment or
other charge overdue in any month and five percent (5%) each month thereafter
until paid in full to help defray the additional cost to Landlord for processing
such late payments, and such late charge shall be additional rent hereunder and
the failure to pay such late charge within ten (10) days alter demand therefor
shall be an additional event of default hereunder. The provision for such late
charge shall be in addition to all of Landlord's other rights and remedies
hereunder or at law and shall not be construed as liquidated damages or as
limiting Landlord's remedies in any manner.

     Pursuit of any of the foregoing remedies shall not preclude pursuit of any
of the other remedies herein provided or any other remedies provided by law (all
such remedies being cumulative), nor shall pursuit of any remedy herein provided
constitute a forfeiture or waiver of any rent due to Landlord hereunder or of
any damages accruing to Landlord by reason of the violation of any of the terms,
provisions and covenants herein contained. No act or thing done by Landlord or
its agents during the term hereby granted shall be deemed a termination of this
lease or an acceptance of the surrender of the premises, and no agreement to
terminate this lease or accept a surrender of said premises shall be valid
unless in writing signed by Landlord. No

                                       15
<PAGE>
 
waiver by Landlord of any violation or breach of any of the terms, provisions
and covenants herein contained shall be deemed or construed to constitute a
waiver of any other violation or breach of any of the terms, provisions and
covenants herein contained. Landlord's acceptance of the payment of rental or
other payments hereunder alter the occurrence of an event of default shall not
be construed as a waiver of such default, unless Landlord so notifies Tenant in
writing. Forbearance by Landlord to enforce one or more of the remedies herein
provided upon an event of default shall not be deemed or construed to constitute
a waiver of such default or of Landlord's right to enforce any such remedies
with respect to such default or a subsequent default. If, on account of any
breach or default by Tenant in Tenant's obligations under the terms and
conditions of this Lease, it shall become necessary or appropriate for Landlord
to employ or consult with an attorney concerning or to enforce or defend any of
Landlord's rights or remedies hereunder, Tenant agrees to pay any attorney's
fees so incurred.

     Without limiting the foregoing, Tenant hereby: (i) appoints and designates
C T Corporation System, 208 South LaSalle Street, Chicago, Illinois, or any
other party Landlord may from time to time hereinafter designate, by notice to
Tenant, as Tenant's true and lawful agent for service of process only, and
agrees that such service of process upon such party shall constitute personal
service of such process upon Tenant (provided, however, Landlord does not hereby
waive the right to serve Tenant with process by any other lawful means); (ii)
expressly waives any right to trial by jury; and (iii) expressly waives the
service of any notice under any existing or future law of the State of Illinois
applicable to landlords and tenants.

     Tenant hereby constitutes and irrevocably appoints any attorney of any
court to be the true and lawful attorney of Tenant, and, in the name. place and
stead of Tenant, to appear for and on behalf of Tenant in any court of record at
any time in any suit or suits brought against Tenant for the enforcement of any
right hereunder by Landlord, to waive the issuance and service of process and
trial or jury, and, from time to time, to confess judgment or judgments in favor
of Landlord and against Tenant for any rent, including any amounts treated as
additional rent hereunder, other charges, and interest thereon due hereunder by
Tenant to Landlord and not paid and for costs of suit and for a reasonable
attorney's fee in favor of Landlord to be fixed by the court, and to release all
errors that may occur or intervene in such proceedings, including the issuance
of execution upon any such judgment, and to stipulate that no appeal shall be
prosecuted from such judgment or judgments, or that no proceedings in chancery
or otherwise shall be filed or prosecuted to interfere in any way with the
operation of such judgment or judgments or of any execution issued thereon or
with any supplemental proceedings taken by Landlord to collect the amount of any
such judgment or judgments, and to consent that execution on any judgment or
decree in favor of Landlord and against Tenant may issue to forthwith.


     19. [Intentionally Omitted]
     
Mortgages. Tenant accepts this lease subject and subordinate to any mortgage(s)
and/or deed(s) of trust now or at any time hereafter constituting a lien or
charge upon the premises or the improvements situated thereon, provided,
however, that if the mortgagee, trustee, or holder of any such mortgage or deed
of trust elects to have Tenant's interest in this lease superior to any such
instrument, then by notice to Tenant from such mortgagee, trustee or holder,
this lease shall be deemed superior to such lien, whether this lease was
executed before or after said mortgage or deed of trust. Tenant shall at any
time hereafter on demand execute any instruments, releases or

                                       16
<PAGE>
 
other documents which may be required by any mortgagee for the purpose of
subjecting and subordinating this lease to the lien of any such mortgage or for
the purpose of evidencing the superiority of this lease to the lien of any such
mortgage, as may be the case.

     21. Landlord's Liability.  In no event shall Landlord's liability for any
breach of this lease exceed the amount of rental then remaining unpaid for the
then current term (exclusive of any renewal periods which have not then actually
commenced). This provision is not intended to be a measure or agreed amount of
Landlord's liability with respect to any particular breach, and shall not be
utilized by any court or otherwise for the purpose of determining any liability
of Landlord hereunder, except only as a maximum amount not to be exceeded in any
event.
       
     22. Mechanic's and Other Liens.  Tenant shall have no authority, express or
implied, to create or place any lien or encumbrance of any kind or nature
whatsoever upon, or in any manner to bind, the interest of Landlord in the
premises or to charge the rentals payable hereunder for any claim in favor of
any person dealing with Tenant, including those who may furnish materials or
perform labor for any construction or repairs, and each such claim shall affect
and each such lien shall attach to, if at all, only the leasehold interest
granted to Tenant by this instrument. Tenant covenants and agrees that it will
pay or cause to be paid all sums legally due and payable by it on account of any
labor performed or materials furnished in connection with any work performed on
the premises on which any lien is or can be validly and legally asserted against
its leasehold interest in the premises or the improvements thereon and that it
will save and hold Landlord harmless from any and all loss, cost or expense
based on or arising out of asserted claims or liens against the leasehold estate
or against the right, title and interest of the Landlord in the premises or
under the terms of this lease. Tenant will not permit any mechanic's lien or
liens or any other liens which may be imposed by law affecting Landlord's or its
mortgagees' interest in the premises or any building or other improvement of
which the premises are a part to be placed upon the premises or any building or
improvement thereon during the term hereof, and in case of the filing of any
such lien Tenant will promptly pay same. If any such lien shall remain in force
and effect thirty (30) days after written notice thereof from Landlord to
Tenant, Landlord shall have the right and privilege at Landlord's option of
paying and discharging the same or any portion thereof without inquiry as to the
validity thereof, and any amounts so paid, including expenses and interest,
shall be so much additional indebtedness hereunder due from Tenant to Landlord
and shall be repaid to Landlord immediately on rendition of a bill therefor.
Notwithstanding the foregoing, Tenant shall have the right to contest any such
lien in good faith and with all due diligence so long as any such contest, or
action taken in connection therewith, protects the interest of Landlord and
Landlord's mortgagee in the premises and Landlord and any such mortgagee are, by
the expiration of said thirty (30) day period, furnished such protection, and
indemnification against any loss, cost or expense related to any such lien and
the contest thereof as are satisfactory to Landlord and any such mortgagee.

     23. Notices.  Each provision of this instrument or of any applicable
governmental laws, ordinances, regulations and other requirements with reference
to the sending, mailing or delivery of any notice or the making of any payment
by Landlord to Tenant or with reference to the sending, mailing or delivery of
any notice or the making of any payment by Tenant to Landlord shall be deemed to
be complied with when and if the following steps are taken:

                                       17
<PAGE>

     other entity at such other address as Landlord may specify from time to
     time by written notice delivered in accordance herewith.

          (b) All payments required to be made by Landlord to Tenant hereunder
     shall be payable to Tenant at the address hereinbelow set forth, or at such
     other address within the continental United States as Tenant may specify
     from time to time by written notice delivered in accordance herewith.

          (c) Any notice or document required or permitted to be delivered
     hereunder shall be deemed to be delivered, whether actually received or
     not, when deposited in the United States Mail, postage prepaid, Certified
     or Registered Mail, addressed to the parties hereto at the respective
     addresses set out below, or at such other address as they have theretofore
     specified by written notice delivered in accordance herewith:

          LANDLORD:                                     TENANT:
LaSalle National Bank Trust #52157         MODERN WHOLESALE DRUG MIDWEST, INC.
c/o Trammell Crow Company                  3400 W. Lake Avenue

among themselves for their joint execution of such a notice specifying some
individual at some specific address for the receipt of notices and payments to
Landlord; if and when included within the term "Tenant", as used in this
instrument, there are more than one person, firm or corporation, all shall
jointly arrange among themselves for their joint execution of such a notice
specifying some individual at some specific address within the continental
United States for the receipt of notices and payments to Tenant. All parties
included within the terms "Landlord" and "Tenant", respectively, shall be bound
by notices given in accordance with the provisions of this paragraph to the same
effect as if each had received such notice.

     24. Miscellaneous.
     A.  Words of any gender used in this lease shall be held and construed to
include any other gender, and words in the singular number shall be held to
include the plural, unless the context otherwise requires.

     B.  The terms, provisions and covenants and conditions contained in this
lease shall apply to, inure to the benefit of, and be binding upon, the parties
hereto and upon their respective heirs, legal representatives, successors and
permitted assigns, except as otherwise herein expressly provided Landlord shall
have the right to assign any of its rights and obligations under this lease and
Landlord's grantee or Landlord's successor, as the case may be, shall upon such
assignment,

                                       18
<PAGE>
 
become Landlord hereunder, thereby freeing and relieving the grantor or
assignor, as the case may be, of all covenants and obligations of Landlord
hereunder. Each party agrees to furnish to the other, promptly upon demand, a
corporate resolution, proof of due authorization by partners, or other
appropriate documentation evidencing the due authorization of such party to
enter into this lease. Nothing herein contained shall give any other tenant in
the building of which the premises are a part any enforceable rights either
against Landlord or Tenant as a result of the covenants and obligations of
either party set forth herein.

     C.  The captions inserted in this lease are for convenience only and in no
way define, limit or otherwise describe the scope or intent of this lease, or
any provision hereof, or in any way affect the interpretation of this lease.

     D.  Tenant shall at any time and from time to time within ten (10) days
after written request from Landlord execute and deliver to the Landlord or any
prospective Landlord or mortgagee or prospective mortgagee a sworn and
acknowledged estoppel certificate, in form reasonably satisfactory to Landlord
and/or Landlord's mortgagee or prospective mortgagee certifying and stating as
follows: (i) this lease has not been modified or amended (or if modified or
amended, setting forth such modifications or amendments); (ii) this lease as so
modified or amended is in full force and effect (or if not in full force and
effect, the reasons therefor); (iii) the Tenant has no offsets or defenses to
its performance of the terms and provisions of this lease, including the payment
of rent, of it there are any such defenses or offsets, specifying the same; (iv)
Tenant is in possession of the premises, if such be the case; (v) if an
assignment of rents or leases has been served upon Tenant by a mortgagee or
prospective mortgagee, Tenant has received such assignment and agrees to be
bound by the provisions thereof; and (vi) any other accurate statements
reasonably required by Landlord or its mortgagee or prospective mortgagee. It is
intended that any such statement delivered pursuant to this subsection may be
relied upon by any prospective purchaser or mortgagee and their respective
successors and assigns and Tenant shall be liable for all loss, cost or expense
resulting from the failure of any sale or funding of any loan caused by any
misstatement contained in such estoppel certificate. Tenant hereby irrevocably
appoints Landlord or if Landlord is a trust, Landlord's beneficiary, as 
attorney-in-fact for the Tenant with full power and authority to execute and
deliver in the name of Tenant such estoppel certificate if Tenant fails to
deliver the same within such ten (10) day period and such certificate as signed
by Landlord or Landlord's beneficiary, as the case may be, shall be fully
binding on Tenant, if Tenant fails to deliver a contrary certificate within five
(5) days after receipt by Tenant of a copy of the certificate executed by
Landlord or Landlord's beneficiary, as the case may be, on behalf of Tenant. In
addition to any other remedy Landlord may have hereunder, Landlord may, at its
option, if Tenant does not deliver to Landlord an estoppel certificate as set
forth above within fifteen (15) days after Tenant is requested so to do, cancel
this lease effective the last day of the then current month, without incurring
any liability on account thereof, and the term hereby granted is expressly
limited accordingly.

     E.  This lease may not be altered, changed or amended except by an
instrument in writing signed by both parties hereto.

     F.  All obligations of Tenant hereunder not fully performed as of the
expiration or earlier termination of the term of this lease shall survive the
expiration or earlier termination of the term hereof, including without
limitation, all payment obligations with respect to taxes and insurance

                                       19
<PAGE>
 
and all obligations concerning the condition of the premises. Upon the
expiration or earlier termination of the term hereof, and prior to Tenant
vacating the premises, Landlord and Tenant shall jointly inspect the premises
and Tenant shall pay to Landlord any amount estimated by Landlord as necessary
to put the premises, including without limitation heating and air conditioning
systems and equipment therein, in good condition and repair. Any work required
to be done by Tenant prior to its vacation of the premises which has not been
completed upon such vacation, shall be completed by Landlord and billed to
Tenant. Tenant shall also, prior to vacating the premises, pay to Landlord the
amount, as estimated by Landlord, of Tenant's obligation hereunder for unpaid
real estate taxes for the years during the term of this lease for which such
taxes are a lien against the premises, and insurance premiums for the year in
which the lease expires or terminates. All such amounts shall be used and held
by Landlord for payment of such obligations of Tenant hereunder, with Tenant
being liable for any additional costs therefor upon demand by Landlord, or with
any excess to be returned to Tenant after all such obligations have been
determined and satisfied, as the case may be. Any security deposit held by
Landlord shall be credited against the amount payable by Tenant under this
subparagraph 24F.

     G.  If any clause, phrase, provision or portion of this lease or the
application thereof to any person or circumstance shall be invalid or
unenforceable under applicable law, such event shall not affect, impair or
render invalid or unenforceable the remainder of this lease nor any other
clause, phrase, provision or portion hereof, nor shall it affect the application
of any clause, phrase, provision or portion hereof to other persons or
circumstances, and if is also the intention of the parties to this lease that in
lieu of each such clause, phrase, provision or portion of this lease that is
invalid or unenforceable, there be added as a part of this lease contract a
clause, phrase, provision or portion as similar in terms to such invalid or
unenforceable clause, phrase, provision or portion as may be possible and be
valid and enforceable.

     H.  Submission of this lease shall not be deemed to be a reservation of the
premises. Landlord shall not be bound hereby until its delivery to Tenant of an
executed copy hereof signed by Landlord, already having been signed by Tenant,
and until such delivery Landlord reserves the right to exhibit and lease the
premises to other prospective tenants. Notwithstanding anything contained herein
to the contrary Landlord may withhold delivery of possession of the premises
from Tenant until such time as Tenant has paid to Landlord the security deposit
required by subparagraph 2B hereof and the first month's rent as set forth in
subparagraph 2A hereof.

     I.  All references in this lease to "the date hereof" or similar references
shall be deemed to refer to the last date in point of time, on which all parties
hereto have executed this lease.

     J.  Tenant's "proportionate share" as used in this lease shall mean a
fraction, the numerator of which is the rentable area (other than any designated
parking or loading areas) contained in the premises and the denominator of which
is the rentable area contained in the building, in each case, as determined by
Landlord. For purposes hereof the numerator is 81,225 and the denominator is 
                                               -------              
121,225 and Tenant's proportionate share is sixty seven and 00/100 percent ( %) 
- -------                                     ----------------------
(67.0%).

     25. Land Trustee's Exculpation. If the Landlord executing this lease is a
trust, the following paragraph is hereby made a part hereof:

     This lease is executed by LaSalle National Bank not personally but as
                               ---------------------   
Trustee as aforesaid, in the exercise of the power and authority conferred upon
and vested in it as such Trustee, and under the express direction of the
beneficiaries of a certain Trust Agreement dated March 2, 1977 and known as
                                                 -------------

          -----    ---------------------------
Agreement this lease is expressly made subject. It is expressly understood and
agreed that nothing in the Trust Agreement or in this lease contained shall be
construed as creating any liability whatsoever against said Trustee personally.
and in particular without limiting the generality of the foregoing, there shall
be no personal liability to pay any indebtedness accruing hereunder or to
perform any covenant, either express or implied, herein contained, or to keep,
preserve or sequester any property of said Trust, or to manage or control such
property or to be responsible for the upkeep, inspection, maintenance or repair
of such property or for the collection of rents or rental of property or for the
conduct of any business which is carried on upon such premises, and that all
personal liability of said Trustee of every sort, if any, is hereby expressly
waived by Tenant, and by every person now or hereafter claiming any right or
security hereunder; and that so far as said Trustee is concerned the owner of
any indebtedness or liability accruing hereunder shall look solely to the
premises hereby leased for the payment thereof.

Landlord is required, Landlord agrees that it shall not unreasonable withhold or
delay such consent or approval.

of grace after written notice given by Landlord before being in default for
failure to pay rent, but such period of grace can not be utilized by Tenant more

5.   HAZARDOUS SUBSTANCES
     --------------------

          (a) Tenant shall not use, store, dispose, handle, transport, release,
   discharge or generate any Hazardous Substances (as defined in subparagraph
   (f) below), in, on, to, under, from or about the Premises or Building without
   Landlord's prior written consent, which consent may be granted on conditions
   or withheld in Landlord's sole and absolute discretion.  Tenant warrants and
   agrees that if Landlord grants its consent to Tenant's use, storage,
   disposal, handling, release, discharge, generation or transport shall be
   conducted in strict accordance with all Environmental Laws (as defined in
   subparagraph (f) below).  Any consent or approval by Landlord of Tenant's
   use, storage, disposal, transport, handling, discharge, release or generation
   of Hazardous Substances shall not constitute an assumption of risk respecting
   the same nor a warranty or certification by Landlord that Tenant's proposed
   use, storage, disposal, handling, release, discharge, generation or transport
   of any such Hazardous Substances is safe or reasonable or in compliance with
   Environmental Laws.  Tenant shall maintain current all permits required for
   its operations, including, without limitation, those for the use, storage,
   handling, transport, discharge, release, generation and/or disposal of
   Hazardous Substances.

          (b) Release or discharge of Hazardous Substances into the soil or into
   ground water shall constitute a material default under this Lease. Tenant
   acknowledges that a Tenant of nonresidential property who knows

                                       24
<PAGE>
 
     or has reason to know that a material amount of a hazardous substance has
     been released on or beneath its premises is to promptly notify the
     Landlord. Failure to provide such notice to Landlord shall constitute a
     material default under this Lease. In the event of such default, Landlord
     shall have the right to (i) terminate this Lease and collect damages,
     inclusive of the cost of cleanup of any Hazardous Substances released into
     the soil or groundwater; or (ii) require the cleanup of contamination while
     still enforcing the remaining terms of this Lease.

          (c) Tenant expressly agrees that Landlord shall have the right to
     enter the Premises to inspect the Premises and/or perform an environmental
     investigation and assessment of the Premises (the "Environmental
     Assessment") upon reasonable notice to Tenant (not less than 72 hours), and
     that this right of entry shall include the right to test for soil and
     groundwater contamination. If Landlord so reasonably requires, Tenant shall
     comply, at its sole cost and expense, with all recommendations contained in
     any Environmental Assessment, including, without limitation, any
     recommendation with respect to the precautions that should be taken with
     respect to activities on the Premises or Building or any recommendations
     for additional testing and studies to detect the presence of Hazardous
     Substances.

          (d) Tenant shall indemnify, defend, (by counsel reasonably acceptable
     to Landlord), protect and hold Landlord, and each of Landlord's officers,
     directors, shareholders, employees, agents, attorneys, successors and
     assigns, free and harmless from and against any and all claims,
     liabilities, penalties, forfeitures, losses or expenses (including, without
     limitation, attorney's fees and costs and court costs) or death of or
     injury to any person or damage to any property whatsoever, arising from or
     caused in whole or in part, directly or indirectly, by Tenant's use,
     storage, handling, transportation, disposal, release, threatened release,
     discharge or generation of Hazardous Substances to, in, on, under, about or
     from the Premises or Building or Tenant's failure to comply with any
     Environmental Law. For purposes of the indemnity provisions hereof any acts
     or omissions of Tenant, or by employees, agents, assignees, contractors or
     subcontractors of Tenant or others acting for or on behalf of Tenant
     (whether or not they are negligent, intentional, willful or unlawful) shall
     be strictly attributable to Tenant. This indemnification shall include
     without limitation (a) personal injury claims, (b) the payment of liens,
     (c) diminution in the value of the Premises or Building or the property on
     which they are located, (d) damages for the loss or restriction on use of
     the Premises or Building, (e) sums paid in settlement of claims, (f)
     reasonable attorneys' fees and costs, consulting fees and costs and expert
     fees and costs, (g) the cost of any investigation of site conditions, and
     (h) the cost of any repair, clean-up health or other Environmental
     Assessments, remedial, closure, removal, or restoration work,
     decontamination or detoxification if required by any governmental or quasi-
     governmental agency or body having jurisdiction or deemed necessary in
     Landlord's reasonable judgment. The indemnification contained herein shall
     survive the expiration of earlier termination of this Lease. This
     indemnification is intended to constitute an indemnity agreement within the
     meaning of Section 9607 (e) (1) of the Comprehensive Environmental
     Response, Compensation and Liability Act of 1980 (42 USC 9607 (e) (1).

          (e) Upon expiration or earlier termination of this Lease, Tenant shall
     remove from the Premises any trade fixtures, furnishings and/or equipment,
     including those associated with the use, storage, handling, transport,
     discharge, release, generation or disposal of Hazardous Substances and
     perform any closure work, investigation and environmental remedial work
     required by any Environmental Laws or by any other applicable laws,
     ordinances, regulations, or permits by any governmental authority having
     jurisdiction. Removal and disposal of any and all such equipment or
     fixtures shall be performed in strict accordance with all Environmental
     Laws and all other applicable laws, regulations and government orders.

          (f) As used in this Lease, the term "Hazardous Substances" shall mean
     hazardous wastes, hazardous chemicals, flammable or explosive materials,
     radioactive materials, toxic materials or related materials (whether
     potentially injurious to persons or property and whether potentially
     injurious by themselves or in combination with other materials), including,
     but not limited to, any waste, chemical, substance or material now or
     hereafter determined by any federal, state or local governmental agency of
     authority having jurisdiction to be hazardous to human health or the
     environment or that is or becomes regulated by such agency or authority
     (including, but not limited to, those materials listed in the United States
     Department of Transportation Hazardous Materials Table [49 CFR 172.101] as
     amended from time to time), that were released to the environment,
     including, without limitation, the soil, groundwater and/or air, at the
     Premises or Building. As used in this Lease, the term "Environmental Laws"
     shall mean any and all present and future

                                       25
<PAGE>
 
     federal, state and local laws (whether under common law, statute, rule,
     regulation or otherwise), requirements under permits issued with respect
     thereto, and other requirements of governmental authorities relating to the
     environment or to any Hazardous Substance (including, without limitation,
     to the Comprehensive Environmental Response, Compensation, and Liability
     Act of 1980 (42 U.S.C. 9601, et seq.) as heretofore or hereafter amended
                                  ------     
     from time to time.

          (g) Tenant shall immediately advise Landlord in writing of, and
     provide Landlord with a copy of: (i) any notices of violation or potential
     or alleged violation of any Environmental Law that are received by Tenant
     from any governmental agency; (ii) any and all inquiry, investigation,
     enforcement, clean-up, removal or other governmental or regulatory actions
     instituted or threatened relating to Tenant or the Premises or Building;
     and (iii) all claims made or threatened by any third-party against Tenant
     or the Premises or Building relating to any Hazardous Substances.

          (h) With reference to Paragraph 11 of this Lease, if the proposed
     assignee's or subtenant's activities in, on, or about the Premises or
     Building involve the use, handling, storage, transport, discharge, release,
     generation or disposal of any Hazardous Substances other than those used by
     Tenant or in quantities and processes different from Tenant's uses
     permitted hereunder, it shall be reasonable for Landlord to withhold its
     consent to such assignment or sublease in light of the risk of
     contamination posed by such activities unless Tenant established beyond a
     reasonable doubt that such assignee's or subtenant's activities pose no
     greater risk of contamination to the Premises and Building than Tenant's
     permitted activities and use of the Premises and Building in view of the
     (a) quantities, toxicity and other properties of the Hazardous Substances
     to be used by such assignee or subtenant, (b) the precautions against a
     release of Hazardous Substances such assignee or subtenant agrees to
     implement, (c) such assignee's or subtenant's financial condition as it
     relates to its ability to pay for the cost to clean up a major release of
     Hazardous Substances, and (d) such assignee's or subtenant's policy and
     historical record respecting its willingness to respond to and clean up a
     release of Hazardous Substances.

6.   Paragraphs 27., 31., and 32. are deleted.

7.   Landlord at its sole cost and expense shall provide the following
     improvements to the new space as shown on Exhibit "B":

     a.  Demolish the existing office area

     b.  Cap existing plumbing within the space

     c.  Obtain necessary permits for completing the work

     d.  Demolish the wall block that divides the space in half

     e.  Provide two 12'x 14' knock-out openings in the wall between existing
         facility and additional storage facility

     f.  Demolish the electrical conduit and switches in the new warehouse and
         connect the warehouse lighting to Rugby Laboratories' power panel

     g.  Clean and re-seal the warehouse floor in the new area with two coats of
         polyurethane floor sealant or equivalent floor sealant

8.   Exhibit "B" is attached hereto and made a part hereof.

9.   Provided this Lease is in full force and effect and the Tenant shall not be
in default hereunder, Tenant may renew and extend this Lease for three (3) years
from the fifth (5th) anniversary of the commencement date of the original term
of this Lease Amendment, by notice in writing delivered to Landlord not less
than one hundred eighty (180) days prior to the expiration date of the then
current term of this Lease. All of the covenants, conditions and

                                       26
<PAGE>
 
provisions of this Lease shall thereupon be applicable during each such
additional three (3) year term, except that the amount of the monthly rental to
be paid by Tenant to Landlord shall be adjusted by multiplying the monthly
rental during the Lease Amendment term by the Consumer Price Index--United
States, All Items for all Urban Consumers, published by the Bureau of Labor
Statistics of the Department of Labor, for the month of April 1999 (third month
prior to the last month of the then current term), and dividing the product by
such Consumer Price Index for the month of April 1994 (third month prior to
commencement of Lease Amendment term), adjusted, however, to reflect any change
in the base year of such Index which may have been made by said Bureau of Labor
Statistics between said monthly periods. For purposes of this provision, this
Lease Amendment shall be deemed to commence on July 1, 1994, and the first five
(5) year term of this Lease Amendment shall terminate on June 30, 1999. In no
event shall the amount of the rental during the option (renewal) term be less
than during the Lease Amendment term. In no event shall this renewal be in
effect if the premises are subleased or available for sublease under any of the
provisions of this lease agreement.
 
     This renewal is personal to the Tenant named in the Lease or any Tenant's
Affiliate as defined in Paragraph 11C. If Tenant subleases any portion of the
property or assigns or otherwise transfers any interest under the Lease to any
entity other than a Tenant Affiliate prior to the exercise of the renewal
(whether with or without Landlord's consent), such renewal and any succeeding
renewal shall lapse. If Tenant subleases any portion of the property or assigns
or otherwise transfers any interest of Tenant under the Lease to any entity
other than a Tenant Affiliate after the exercise of renewal but prior to the
commencement of the respective extension (whether with or without Landlord's
consent), such renewal and any succeeding renewals shall lapse and the lease
term shall expire as if such renewal was not exercised.

10.  Landlord hereby agrees to provide Tenant with the right to lease additional
space in the building commonly known as 3450 W. Lake, Glenview, Illinois, when
and if such additional space should become available during the term of this
Lease.  Said right to lease shall be junior to any options for extensions held
by adjacent tenants, but shall be superior to any leases not in effect or
proposed.  In the event this right to lease is exercised by Tenant, Tenant shall
have the right to lease the entire additional space consisting of 24,000 square
feet, but shall specifically not have the right to lease only part of said
additional space under the provisions of this paragraph.

     In the event Tenant desires to exercise the right to lease said additional
space, Tenant shall so notify Landlord in writing not less than two hundred
seventy (270) days prior to the availability of such additional space, and shall
return an executed lease containing the same terms and conditions as does this
Lease for any such additional space within thirty (30) days after Landlord
submits said Lease to Tenant.  The rental for any such additional space shall be
based on rental rates prevailing in the open market for similar properties at
the time of notice by Tenant of Tenant's desire to exercise the right granted
under this paragraph.

     Landlord specifically shall not be obligated to notify Tenant of the
availability of said additional space unless Tenant has advised Landlord of
Tenant's intention to lease said additional space as provided for hereinabove.
In no event shall this right to lease additional space be in effect if the
premises are subleased or available for sublease under any of the provisions of
this Lease Agreement.

All the terms and provisions of the Lease not modified expressly or by necessary
implication herein shall be and remain in full force and effect.
