ITEM 1.           BUSINESS

Company Overview

         Pharmaceutical Product Development, Inc. ("PPD" or "the Company")
provides a broad range of research and development and consulting services in
the life and discovery sciences. PPD Pharmaco, Inc. is the Company's life
sciences subsidiary. The Company believes that PPD Pharmaco is the fourth
largest contract research organization ("CRO") in the world, providing
integrated product development resources on a global basis to complement the
research and development activities of companies in the pharmaceutical and
biotechnology industries. PPD Discovery, Inc., the Company's discovery sciences
subsidiary, focuses on the discovery segment of the research and development
outsourcing market.

     LIFE SCIENCES GROUP

         The Company's Life Sciences Group provides services through PPD
Pharmaco, Inc. and its wholly owned subsidiaries (collectively "PPD Pharmaco")
in the Americas (United States, Canada, South America), Africa, Asia, Europe and
the Pacific Rim. PPD Informatics, a division of PPD Pharmaco, provides software
development and system integration services to the pharmaceutical and
biotechnology industries.

         PPD PHARMACO provides its clients high quality services designed to
reduce drug development time. Reduced development time allows the client to get
its products into the market faster and to maximize the period of marketing
exclusivity and the economic return for such products. In addition, PPD
Pharmaco's integrated services offer its clients a variable cost alternative to
the fixed costs associated with internal drug development. PPD Pharmaco's
professional CRO services include Phase I clinical testing, laboratory services,
patient and investigator recruitment, Phase II-IV clinical trial monitoring and
management, clinical data management and biostatistical analysis, regulatory
consulting and submissions, medical writing, pharmacovigilance, and healthcare
economics and outcomes research. The Company believes that it is one of a few
CROs in the world capable of providing such a broad range of clinical
development services.

         PPD INFORMATICS became a division of the Company through the Company's
acquisition of Belmont Research, Inc., in March 1997. PPD Informatics clients
include international and domestic pharmaceutical and biotechnology companies,
scientific software vendors and government agencies including the FDA. PPD
Informatics develops specialized software products to support different aspects
of the pharmaceutical research and development process, including drug
discovery, clinical trials and regulatory review. Current PPD Informatics
software products include RESOLVE(TM), which manages data queries to
investigator sites, TABLETRANS(R), which enables ease of data transformation,
and CROSSGRAPHS(R) which is used for exploration and presentation of research
data.

         During 1998, the Life Sciences Group also included Intek Labs, Inc.
("Intek") which was acquired in November 1997. Intek provides molecular
genotyping, phenotyping and large-scale genomic DNA purification and archiving
services through its Good Laboratory Practice (GLP)-certified laboratories.
Intek also furnishes pharmaco-genetic services for clinical trials. In February
1999, Intek became a subsidiary of PPGx, Inc. ("PPGx"), the Company's
pharmacogenomics joint venture with Axys Pharmaceuticals, Inc. PPGx provides
comprehensive pharmacogenomics products and services to pharmaceutical and
biotechnology companies. Pharmacogenomics is the use of genetic information to
predict the safety, toxicity and/or efficacy of drugs in individual patients or
groups of patients. Pharmacogenomics is becoming widely adopted as an essential
drug discovery and development tool and increasingly important as part of an
individual's diagnosis and treatment regimen. The Company has exclusive
marketing rights to PPGx pharmacogenomics products and services. The Company
also owns a minority position in PPGx with the option to increase its ownership
share.

         During the first two months of 1998, the Life Sciences Group also
included Clinix International, Inc., which owned the business and substantially
all of the assets of Chicago Center for Clinical Research ("CCCR"), a nationally
recognized organization which conducts clinical trials in the pharmaceutical,
food and nutrition industries. The Company sold substantially all of the assets
of CCCR in February 1998.

     DISCOVERY SCIENCES GROUP

         PPD DISCOVERY, INC. ("PPD DISCOVERY") was established in June 1997 when
the Company acquired SARCO, Inc. ("SARCO"), a combinational chemistry company,
and the GSX System, a functional genomics platform technology. PPD Discovery
focuses on the discovery research segment of the research and development
outsourcing market. In May 1998, the Company created GenuPro, Inc. ("GenuPro"),
a wholly owned subsidiary, which holds licenses to a number of compounds in the
genitourinary field. GenuPro manages the research and development of these
compounds.

     ENVIRONMENTAL SCIENCES GROUP

         During 1998, the Company also owned an environmental sciences
consulting and management subsidiary, APBI Environmental Sciences Group, Inc.,
which operated under the trade name ENVIRON. ENVIRON was acquired by the Company
in September 1996 as part of the Applied Bioscience International Inc.
acquisition. ENVIRON provides a broad range of scientific, technical and
strategic management consulting services that address a wide variety of public
health and environmental issues related to the presence of chemicals in foods,
drugs, medical devices, consumer products, the workplace and the environment.
ENVIRON's services are concentrated in the assessment and management of chemical
risk and are characterized by engagements supporting private sector clients with
complex, potentially high liability concerns. The Company sold ENVIRON to the
management of ENVIRON effective January 1999.

Industry Overview

     LIFE SCIENCES GROUP

         The CRO industry provides independent product development services to
the pharmaceutical and biotechnology industries and derives substantially all of
its revenue from the research and development expenditures of these companies.
The CRO industry has evolved from providing limited clinical services in the
1970s to a full-service industry today that encompasses the clinical research
process (including pre-clinical evaluations), study design, clinical trial
management, data collection, biostatistical analysis and product registration
support. All of these services are provided in accordance with applicable
government regulations covering clinical trials and the drug approval process in
the jurisdictions where the services are provided, including the regulations of
the United States Food and Drug Administration ("FDA"), the European Medicines
Evaluation Agency ("EMEA") and other regulatory authorities.

         The healthcare industry is subject to changing political, economic and
regulatory influences that may affect the pharmaceutical and biotechnology
industries. Implementation of government healthcare reform may adversely affect
research and development expenditures by pharmaceutical and biotechnology
companies, which could decrease the business opportunities available to the
Company. The Company is unable to predict the likelihood of such or similar
legislation being enacted into law or the effects such legislation would have on
the Company. As a general matter, the clinical CRO industry is not capital
intensive and the financial costs of entry into the industry are relatively low.
The CRO industry is highly fragmented, with several hundred small,
limited-service providers, several medium-sized CROs and a few full-service CROs
with international capabilities. Although there are few barriers to entry for
small, limited-service providers, the Company believes that there are
significant barriers to becoming a full-service CRO with international
capabilities. Some of these barriers include the cost and experience necessary
to develop broad therapeutic expertise, the ability to manage large, complex
clinical trials, the experience to prepare regulatory submissions, and the
infrastructure and experience to respond to the international needs of clients.

         Historically, pharmaceutical companies, through use of internal
programming resources, produced much of the software used in the drug discovery,
clinical development and regulatory compliance processes. Now, these companies
are also seeking external sources, including the Company's PPD Informatics
division, to meet these automation needs both through custom application
development and through proprietary packaged software. While many companies have
the computer expertise to provide these products and services, the Company
believes that detailed knowledge of the pharmaceutical industry drug discovery
and development process forms a barrier to entry.

         DISCOVERY SCIENCES GROUP

         Drugs are chemical compounds that interact with biological targets in
the body. Discovering and developing new drugs is an extremely expensive and
time-consuming process. Pharmaceutical Research and Manufacturers of American
Association (PhRMA) estimates that the average cost of bringing a drug to market
exceeds $359 million and takes approximately 10-15 years. Recent figures from
the PhRMA, Vector Securities, Inc. and Lehman Brothers analysts' reports
indicate that global research-based pharmaceutical and biotechnology companies
invested approximately $39 billion in R&D activities in 1998. On average, these
companies allocate over 40% of their R&D budget to pre-clinical R&D functions.
Pre-clinical R&D functions include identification and validation of target
chemical compounds, screening to identify lead compounds, chemical optimization
of those leads, toxicology and safety testing in animals, and formulation and
stability testing for the new experimental drug.

         SARCO is a chemical technology company that provides chemical compounds
to the pharmaceutical, biotechnology, agrochemical and animal health industries.
SARCO's core expertise includes the rapid synthesis of large numbers of
compounds for use in the pre-clinical drug discovery and development process as
well as the chemical optimization of those compounds found to have beneficial
biological activity.

         The GSX System identifies targets for drug discovery by the selective
inhibition of genes responsible for key steps in a disease process. The system
is based on the finding that a gene fragment, when introduced into cells,
sometimes specifically inhibits the function of the whole gene from which the
fragment was obtained.

         PPD Discovery markets its products and services to those research-based
companies looking for outsource research support. The Company believes that this
outsourcing trend will continue over the next decade.

The Drug Development Process

         Before a new drug is marketed, the drug must undergo extensive testing
and regulatory review in order to determine that it is safe and effective. The
development process consists of two stages: pre-clinical and clinical. The first
stage is pre-clinical research, in which the new drug is tested IN VITRO (test
tube) and IN VIVO (in animals) generally over a one- to three-year period, in
order to determine the basic biological activity and safety of the drug. The
Company provides Investigational New Drug ("IND") submission preparation and
compilation but does not provide animal-based services in this stage of
development.

         If the drug is perceived to be safe for human testing, the drug then
enters the clinical stage. During the clinical stage, one of the most
time-consuming and expensive parts of the drug development process, the drug
undergoes a series of tests in humans, including healthy volunteers as well as
patients with the targeted disease or condition. The Company provides full
development services for the clinical stage.

         Prior to commencing human clinical trials in the United States, the
sponsor must file an IND application with the FDA. In order to receive IND
status, the sponsor of the new drug must provide available manufacturing data,
pre-clinical data, information about any use of the drug in humans for other
purposes and a detailed plan for the conduct of the proposed clinical trials.
The design of these trials, also referred to as the study protocols, is
essential to the success of the drug development effort, because the protocols
must correctly anticipate the nature of the data to be generated and results
that the FDA will require before approving the drug. In the absence of any FDA
comments within 30 days after the IND filing, human clinical trials may begin.

         Although there is no statutory definition of the structure or design of
clinical trials, human trials usually start on a small scale to assess safety
and then expand to larger trials to test efficacy. These trials are usually
grouped into the following three phases, with multiple trials generally
conducted within each phase:

   o   PHASE I. Phase I trials involve testing the drug on a limited
       number of healthy individuals, typically 20 to 80 persons, to
       determine the drug's basic safety data relating to tolerance,
       absorption, metabolism and excretion as well as other
       pharmacological indications and actions. This phase lasts an average of 
       six months to one year.

   o   PHASE II. Phase II trials involve testing a small number of
       volunteer patients, typically 100 to 200 persons who suffer from
       the targeted disease or condition, to determine the drug's
       effectiveness and dose response relationship. This phase lasts an
       average of one to two years.

   o   PHASE III. Phase III trials involve testing large numbers of
       patients, typically several hundred to several thousand persons,
       to verify efficacy on a large scale, as well as long-term safety.
       These trials involve numerous sites and generally last two to
       three years.


                                       3
<PAGE>

         After the successful completion of all three clinical phases, the
sponsor of a new drug in the United States submits a New Drug Application
("NDA") to the FDA requesting that the product be approved for marketing. The
NDA is a comprehensive, multi-volume filing that includes, among other things,
the results of all pre-clinical and clinical studies, information about the
drug's composition and the sponsor's plans for producing, packaging and labeling
the drug. In addition, while the FDA does not use price as a criterion for
approving a new drug, advisory panels of scientists that help the FDA evaluate
new types of therapies have started taking cost into consideration. The FDA's
review of an NDA can last from a few months (for drugs related to
life-threatening circumstances) to many years, with the average review lasting
18 months. Drugs that successfully complete this review may be marketed in the
United States, subject to any conditions imposed by the FDA.

         As a condition to its approval of a drug, the FDA may require that the
sponsor conduct additional clinical trials following receipt of NDA approval to
monitor long-term risks and benefits, study different dosage levels or evaluate
different safety and efficacy parameters in target patient populations. In
recent years, the FDA has increased its reliance on these trials, known as Phase
IV trials, which allow new drugs that show early promise to reach patients
without the delay associated with the conventional review process. Phase IV
trials usually involve thousands of patients. Phase IV trials also are initiated
by pharmaceutical manufacturers to gain longer market value for an approved
product. For example, large-scale trials would be used to prove efficacy and
safety of new dosage administration forms for approved drugs, such as inhalation
form versus tablets or a sustained-release form versus capsules taken multiple
times per day.

Regulatory Environment

         The market for the services offered by the Company's CRO operations has
developed as a result of significant laws and regulations governing the
development and testing of certain drugs and chemicals as well as the impact of
chemicals on the environment.

         Many countries require safety testing prior to obtaining governmental
approval to market pharmaceutical products. The results of clinical tests
conducted upon pharmaceutical products must be submitted to appropriate
government agencies, such as the FDA in the United States, the EMEA and national
regulatory agencies in Europe, and the Ministry of Health and Welfare in Japan,
as part of the relevant pre-market approval process in individual countries. The
Company's business depends on its ability to comply with these strict and
ever-changing laws and regulations.

Trends Affecting the CRO Industry

         In 1998, worldwide expenditures on research and development by
pharmaceutical and biotechnology companies are estimated to have been $39
billion, of which the Company estimates $8 to $10 billion was spent on drug
development activities of the type offered by the CRO industry. The Company
believes that approximately $4 billion of such spending was outsourced to CROs.

         The Company believes that the outsourcing of drug development
activities by pharmaceutical and biotechnology companies has been increasing and
will continue to increase for the following reasons:

         COST CONTAINMENT PRESSURES

         Market forces and governmental initiatives have placed significant
pressure on pharmaceutical and biotechnology companies to reduce drug prices.
Pressures on profit margins have arisen from increased competition as a result
of patent expiration, market acceptance of generic drugs, and governmental and
private efforts to reduce healthcare costs. In addition, private managed care
organizations are beginning to limit the selection of drugs from which
affiliated physicians may prescribe, thereby further increasing competition
among pharmaceutical and biotechnology companies. The Company believes that the
pharmaceutical industry is responding to these pressures by downsizing
operations, decentralizing the internal research and development process, and
converting the fixed costs of maintaining a research and development
infrastructure to variable costs by outsourcing drug development activities to
CROs. The downsizing of research and development activities also creates demand
for CROs as internal development bottlenecks arise when a large number of
compounds emerge from the research process and need to be pushed through the
development pipeline. In addition, increased pressure to differentiate products
and to generate support for product pricing serves as the foundation for growth
in the area of healthcare economics, both with respect to drugs under
development and to products already on the market.

<PAGE>

         REVENUE ENHANCEMENT THROUGH FASTER DRUG DEVELOPMENT

         Pharmaceutical and biotechnology companies face increased pressure to
bring innovative, patent-protected medicines to market in the shortest possible
time, while following good scientific practices and adhering to government
regulations. Pharmaceutical and biotechnology companies are attempting to
increase the speed of new product development, and thereby maximize the period
of marketing exclusivity and economic returns for their products, by outsourcing
development activities to CROs. The Company believes that CROs, by providing
specialized development services, are often able to perform the needed services
with a higher level of expertise or specialization, and therefore more quickly
than a pharmaceutical or biotechnology company could perform such services
internally. In addition, some pharmaceutical and biotechnology companies are
beginning to contract with large full-service CROs to conduct all phases of
clinical trials for new product programs lasting several years, rather than
separately contracting specific phases of drug development to several different
CROs, an approach which the Company believes may result in shorter overall
development times. This trend may favor large full-service CROs like the
Company, but could also increase competitive pressures and risks.

         BIOTECHNOLOGY INDUSTRY GROWTH

         The United States biotechnology industry has grown rapidly over the
last ten years and is developing significant numbers of new drug candidates that
will require regulatory approval. Many of these new drug candidates are now
moving into clinical development and many biotechnology companies do not have
the necessary staff, expertise or financial resources to conduct clinical trials
on their own. Accordingly, many of these companies have chosen to outsource the
product development process rather than expend significant time and resources to
develop an internal clinical development capability. Further, PPD Pharmaco's
experience suggests that biotechnology companies are increasingly turning to
CROs for their sophisticated regulatory expertise to provide assistance in the
generation of the ideal development plan. Moreover, the biotechnology industry
is expanding into and within Europe, providing growth opportunities for CROs
with international capabilities.

         NEED FOR INTERNATIONAL SUPPORT

         More pharmaceutical and biotechnology companies are attempting
simultaneous filings of registration packages in several major jurisdictions
rather than following the past practice of sequential filings. The studies to
support such registration packages may include a combination of multinational
and domestic trials. Pharmaceutical and biotechnology companies may turn to CROs
for assistance with such trials, as well as collecting, analyzing, integrating
and reporting the data. The Company believes that CROs with an international
presence and management experience in the simultaneous filing of multiple
applications may benefit from these trends.

         CONSOLIDATION IN THE CRO INDUSTRY

         As a result of competitive pressures, the CRO industry is
consolidating. Mergers and acquisitions have resulted in the emergence of
several large, full-service CROs that have the capital, technical and financial
resources to conduct all phases of clinical trials on behalf of pharmaceutical
and biotechnology companies. As pharmaceutical and biotechnology companies
increasingly outsource development, they may increasingly turn to larger CROs
that provide a broad range of clinical services, while at the same time they may
also limit the number of CROs they choose to provide such services. The Company
believes that these trends will further concentrate market share among larger
CROs with a track record of speed, flexibility, responsiveness and overall
development experience and expertise.

Company Strategy

         The Company's fundamental strategy is to distinguish its services on
the basis of superior performance to maximize its clients' return on their R&D
investments. The Company strives to deliver to its clients efficient and
innovative services that accelerate the rate of new product development. The
Company intends to continue to expand the depth and breadth of its services by
(i) capitalizing on its managerial and operational strengths, (ii) focusing on
hiring and training its staff, (iii) focusing on its strategic marketing
initiatives, (iv) developing its services in healthcare economics and
communications consulting, (v) pursuing strategic acquisitions to enhance
discovery and development services, (vi) expanding geographically, (vii)
pursuing opportunities provided by technological advances, and (viii) expanding
on its vertical expertise in five core therapeutic areas.

         The Company differentiates itself from competitors by providing a
continuum of high-quality services, from discovery through aftermarket support.
The Company intends to be a leader in integrating pharmacogenomics in drug
development and research.

         MANAGERIAL AND OPERATIONAL STRENGTH

         The Company is guided by senior management who have spent much of their
careers as research or development experts within major pharmaceutical companies
and who have a record of success bringing drugs to market both nationally and
internationally. PPD Pharmaco concentrates on its core operational strengths in
all phases of clinical studies and other critical path studies such as treatment
INDs. Timely performance is based on parallel drug development processes and
leveraging the knowledge and experience of management and investigators. Basic
medical, scientific and regulatory services continue to be integrated with and
streamlined through various technological advances, all directed toward a
reduction in overall development times. PPD Pharmaco emphasizes efficiencies in
each phase of clinical trials initiation and management, data acquisition, data
management and analysis, and report writing and filing, in order to reduce the
time and cost of obtaining regulatory approval for its clients' products. As a
means of differentiating itself from its competitors, PPD Pharmaco emphasizes
therapeutic area specialization, in particular in the areas of
virology/infectious diseases, cardiopulmonary diseases, neuropyschiatric
disorders, oncology and immunology.

         HIRING AND TRAINING

         The Company believes that its success is based on the quality and
dedication of its employees. The Company strives to hire the best available
people in terms of ability, experience, attitude and fit with the Company's
performance philosophy. New employees are trained extensively, and the Company
believes that it is an industry leader in the thoroughness of its training
programs. In addition, employees are encouraged to continually upgrade and
broaden their skills through internal and external training programs. As new
technologies develop, employees are equipped with and trained to make use of
such technological innovations.

         GLOBAL STRATEGIC MARKETING INITIATIVES

         PPD Pharmaco focuses its integrated marketing and sales efforts on high
volume clients with needs in the service segments and therapeutic areas in which
the Company specializes. Direct salespeople concentrate on a group of assigned
clients, marketing across service segments. PPD Pharmaco's business development
personnel consult with potential clients early in the bidding process in order
to determine their needs. The business development personnel and PPD Pharmaco's
project managers then invest significant time to determine the optimal way to
design and carry out the potential client's proposal. PPD Pharmaco's
recommendations to the potential client with respect to study design and
implementation are an integral part of PPD Pharmaco's bids and an important
aspect of the integrated services that PPD Pharmaco offers to its clients. PPD
Pharmaco believes that its preliminary efforts relating to the evaluation of a
potential client's proposed clinical protocol and implementation plan allows
accelerated commencement of the clinical trial after the contract has been
awarded to PPD Pharmaco.

         Discovery services are marketed through centralized PPD corporate
marketing efforts to supplement localized marketing by scientists to scientists,
with support from appropriate outside consultants. The functional genomics
technology (GSX) is marketed primarily to large pharmaceutical companies, while
combinatorial chemistry is directed more toward biotechnology and virtual
companies.

         The Company sponsors and encourages the participation by its personnel
in a variety of scientific endeavors, including the presentation of papers by
its professional staff at meetings of professional societies and major
conferences, and the publication of scientific articles in respected journals.
The Company believes such activities enhance its reputation for professional
excellence. The Company's core marketing and communications efforts include
advertising in trade journals, participation at scientific conferences,
speakers' bureaus, direct mail, presentation materials and media relations.

         HEALTHCARE ECONOMICS AND OUTCOMES RESEARCH

         The healthcare market in the United States is evolving from a
fragmented system of individual providers with little incentive to control costs
to a managed care system in which large organizations attempt to lower the cost
of healthcare through a number of means. The Company believes that such market
dynamics support the need for healthcare economics analysis and outcomes
research. PPD Pharmaco offers programs integrating such analysis in clinical
development programs to support regulatory approval, as well as pricing,
marketing and reimbursement strategies. While PPD Pharmaco's current focus in
this area is on its traditional client base within the pharmaceutical and
biotechnology industries, both with respect to drugs under development and
products already on the market, PPD Pharmaco expects to extend such services to
payers and providers as well.

<PAGE>

         ACQUISITIONS

         The Company will continue to actively seek strategic acquisitions, both
within and outside current CRO service segments. Acquisition candidates must
provide opportunities for innovation, synergy and growth. The Company's criteria
for acquisitions may include complementary client lists, ability to increase
market share within and across clients, complementary therapeutic area and
service segment strengths, strategic geographic capabilities or particular
process expertise.

         Acquisitions involve numerous risks, including difficulties in the
assimilation of the operations and services of the acquired companies, the
expenses incurred in connection with attempted or successful acquisitions and in
connection with subsequent assimilation of operations and products, the
diversion of management's attention from other business concerns and the
potential loss of key employees of the acquired company. If the Company
consummates any acquisitions in the future, there can be no assurance that such
acquisitions will be successfully integrated into the Company's operations.

         GEOGRAPHICAL EXPANSION

         PPD Pharmaco currently has operations in the Americas (the United
States, Canada, South America), Europe (including Eastern Europe), South Africa,
Asia and the Pacific Rim. PPD Pharmaco has identified certain strategic areas of
promise where CROs currently have limited or no presence and intends to
selectively pursue these and other strategic opportunities internationally.
Geographic expansion involves numerous risks, including up-front expenses,
potential political or economic instability, assimilation of staff and cultural
differences.

         TECHNOLOGICAL ADVANCES

         PPD Pharmaco believes that optimizing the use of information technology
can accelerate the drug development process and yield valuable marketing
information. PPD Pharmaco has experience in the use of information technology in
clinical trial management and offers a wide range of technology-based services,
including initial market research and study design, remote monitoring and data
acquisition, ongoing study management, outcomes research, patient and disease
management, and the filing of Computer Assisted New Drug Applications and
Product License Applications. The Company believes that the use of third-party
systems and selected internally developed software allows it to offer its
clients advanced technology for expediting the drug development process.

Services Offered

      LIFE SCIENCES GROUP

         PPD Pharmaco has designed its various global services to be flexible
and integrated in order to assist its clients in optimizing their research and
development spending through the clinical stages of the drug development
process. PPD Pharmaco provides Phase I clinical testing, laboratory services,
patient and investigator recruitment, Phase II-IV clinical trial monitoring and
management, clinical data management and biostatistical analysis, regulatory
consulting and submission, medical writing, pharmacovigilance, and healthcare
economics and outcomes research for its clients. These resources are provided
individually or as an integrated package of services to meet the client's needs.
PPD Informatics provides innovative software development and system integration
services and creates a data link between discovery and development.

         PHASE I CLINICAL TESTING

         After an Investigational New Drug Application has been filed with the
FDA, human testing of a new drug can begin. The drug is typically first
administered to healthy volunteers to determine the drug's basic safety data
based on tolerance, absorption, metabolism, excretion and other pharmacological
actions. Later, special studies are conducted in volunteers and special patient
populations to further define the drug's overall pharmacological profile. The
Company believes that PPD Pharmaco is one of the industry's largest Phase I
providers with clinical testing services conducted in its 212-bed unit in
Austin, Texas, its 64-bed unit located near Research Triangle Park, North
Carolina and its 52-bed unit in Leicester, England. The Company's professional
nursing staff administers general Phase I safety tests, special population
studies, and bioavailability and bioequivalence testing. Special population
studies may involve the elderly, women or patients with specific diagnoses, such
as renal failure or asymptomatic HIV disease. The Austin, Texas site also has a
Dental Research Center to evaluate new analgesic compounds used in molar
extractions for safety and effectiveness.

         The Company's clinical research studies rely upon the ready
accessibility and willing participation of volunteer subjects. These subjects
generally include volunteers from the communities in which the studies are
conducted, including the Phase I centers in Austin, Research Triangle Park and
Leicester, which to date have provided a substantial pool of potential subjects
for research studies. However, the Company's business could be adversely
affected if the Company were unable to attract suitable and willing volunteers.

                                       7
<PAGE>

         The Company also provides bioavailability and bioequivalence testing
services. This testing is generally conducted each time the dosage, form or
formulation of the drug is modified. It involves administration of the test
compounds and obtaining biological fluids sequentially over time to measure
absorption, distribution, metabolization and excretion of the drug.

         PPD Pharmaco attempts to manage its Phase I services to maximize
scheduling flexibility and efficiency. The services also can integrate with PPD
Pharmaco's other service segments such as laboratory, pharmacokinetic and
biostatistical services. PPD Pharmaco is one of the few full-service CROs
offering Phase I clinical testing in the United States and Europe.

         LABORATORY SERVICES

         PPD Pharmaco provides biodiscovery, bioanalytical and product analysis
services through its Good Laboratory Practice (GLP)-certified laboratories in
Richmond, Virginia and Middleton, Wisconsin. PPD Pharmaco's laboratories analyze
biological fluid samples from animal and human clinical studies. The latter
includes those conducted by PPD Pharmaco's Phase I units for drug and metabolite
content and concentration. PPD Pharmaco currently has over 800 validated assays
available for its clients' use in conducting laboratory analyses, qualifying PPD
Pharmaco for a wide range of assignments. PPD Pharmaco's laboratories also
process fluid samples for pre-clinical studies.

         The Company's biodiscovery group links drug discovery to development by
providing rapid IN VIVO screening of new chemical entities, producing
pharmacokinetic and enzyme-kinetic profiles to assess stability, metabolism and
bioavailability of compounds. This non-GLP, high throughput proof-of-principle
method of screening provides companies with a lower-cost way to quickly assess
viability of multiple lead compounds.

         Product analysis services include dissolution and stability studies,
which are necessary to characterize dosage form release patterns and stability
under various environmental conditions in the intended package for marketing.
These studies must be carried out over the commercial life of products,
beginning at the clinical trial stage. New formulations require the same set of
studies as the original dosage form. Comprehensive measurement services include
Gas Chromatography/Mass Spectrometry, Liquid Chromatography/Mass Spectrometry
(LC/MS and LC/MSMS), High Performance Liquid Chromatography, Gas Chromatography,
Radioimmunoassay and Enzyme Linked Immunosorbent Assay. Support services include
HIV-positive sample handling, sample/data management for kinetic studies from
multi-center trials and sample/data archiving.

         PPD Pharmaco is one of a few full-service CROs able to offer its
clients the advantages of both bioanalytical and product analysis, as well as
Phase I clinical testing.

         PHASE II-IV CLINICAL TRIAL MANAGEMENT

         The core of PPD Pharmaco's business is a comprehensive package of
services for the conduct of Phase II-IV clinical trials, which, in concert with
its other analytical and Phase I testing services, pharmacogenomics and
informatics, allows PPD Pharmaco to offer its clients an integrated package of
clinical management services. The Company has significant clinical trials
experience in the areas of:

   AIDS                         Primary disease and treatment/prophylaxis of
                                opportunistic infections

   Virology                     AIDS, herpes simplex, hepatitis B, chronic
                                hepatitis C

   Women's health               Osteoporosis, oral contraception

         Clients' needs are served by conducting clinical trials through a
dedicated project team. A project manager supervises all aspects of the conduct
of the clinical trial, while PPD Pharmaco's clinical research associates are in
the field monitoring the trial at the various investigational sites where it is
being conducted. Within this project-oriented structure, PPD Pharmaco can manage
every aspect of the clinical trial in Phases II through IV of the drug
development process, including protocol development, case report form ("CRF")
design, feasibility studies, investigator selection, recruitment and training,
site initiation and monitoring, accelerated patient enrollment, development of
training materials for investigators and training of clients' staff.

         PPD Pharmaco monitors its clinical trials in compliance with government
regulations. PPD Pharmaco has adopted global standard operating procedures
("SOPs") which are intended to satisfy regulatory requirements and serve as a
tool for controlling and enhancing the quality of its clinical trials. All PPD
Pharmaco SOPs are in compliance with Good Clinical Practice ("GCP") requirements
and the International Conference on Harmonization ("ICH") standards. The FDA has
adopted the ICH's standards, and, the European Community has agreed to conduct
all studies in accordance with the standards from ICH, which sets global
clinical study standards based on GCP. Data generated during clinical trials are
compiled, analyzed, interpreted and submitted in report form to the FDA or other
relevant regulatory agencies for purposes of obtaining regulatory approval. The
Company provides expert consulting on conducting clinical trials for
simultaneous regulatory submissions to multiple countries.

         PPD Pharmaco provides its clients with one or more of the following
core Phase II-IV clinical trials management services using parallel processing
to accelerate the development process:

         STUDY DESIGN

                  PPD Pharmaco serves its clients in the critical area of study
design by applying its wide development experience in the preparation of study
protocols and CRFs. A study protocol defines the medical issues to be examined
in evaluating the safety and efficacy of a drug, the number of patients required
to produce statistically valid results, the clinical tests to be performed, the
time period over which the study will be conducted, the frequency and dosage of
drug administration, and the exact patient criteria. The success of the study
depends not only on the ability of the protocol to correctly predict
requirements of regulatory authorities, but also on the ability of the protocol
to fit coherently with the other aspects of the development process and the
ultimate marketing strategy for the drug. This process includes healthcare
economic components to support rational pricing and positioning.

                                       9
<PAGE>

         Once the study protocol has been finalized, CRFs must be developed to
record the information to be obtained from the clinical studies. The various
other disciplines involved in the drug development process, including data
management, must work closely with the clinical trial management project team to
assure that the data are recorded in a form that is efficient for subsequent
data entry, management and reporting. Proper CRF design is critical to allowing
investigators and field monitors to conduct their respective jobs quickly,
accurately and effectively.

         INVESTIGATOR RECRUITMENT

         During clinical trials, physicians (also referred to as investigators)
at hospitals, clinics or other locations (also referred to as investigational
sites) supervise administration of the drug to patients. PPD Pharmaco recruits
investigators who contract directly with either the Company or its client. For
large scale trials, or trials with a short start-up timeline, PPD Pharmaco's
Telecommunications Center (TCC) is utilized for investigator recruitment. The
TCC integrates telephony, relational databases, computerized scripts, and
customized tracking software to provide high-speed results and to manage high
volumes of inbound and outbound calls for investigator recruitment. Recently,
the TCC staff recruited and obtained IRB approval for over 900 investigators in
12 weeks. The successful rapid identification and recruitment of investigators
who have the appropriate expertise and an adequate base of patients who satisfy
the requirements of the study protocol are critical to the timely completion of
the trial.

         PPD Pharmaco maintains and constantly expands and refines its
computerized database of over 20,500 investigators. Information regarding PPD
Pharmaco's experience with these investigators, including factors relevant to
rapid study initiation, are contained in the database. This information allows
project managers to efficiently choose the appropriate investigators for a
particular study.

         STUDY MONITORING

         PPD Pharmaco provides study-monitoring services, which include
investigational site initiation, patient enrollment assistance and data
collection through subsequent site visits. These visits also serve to assure
that data is gathered according to GCP, according to the requirements of the
client and applicable regulatory authorities, and as specified in the study
protocol.

         Project management and field-monitoring services are the operational
heart of Phase II and III clinical studies. In many instances, a project's
timely completion is based on meeting deadlines during the first few months of
study initiation. Therefore, PPD Pharmaco focuses at an early stage on
identifying and quickly completing the critical rate-limiting steps of screening
and selecting qualified investigators, processing pre-study regulatory
paperwork, obtaining investigative review board approvals and scheduling
investigational site initiation visits. Drugs under study cannot be released to
the investigational sites, and thus the study cannot begin, until these
activities have been completed.

         Following study initiation, PPD Pharmaco utilizes a number of
appropriate methods of accelerating patient recruitment. This may involve PPD
Pharmaco's integrated systems of telephone recruitment, telefaxing and media
advertising. As with Phase I clinical trials, rapid patient recruitment is
critical to the Company's success in providing services to maximize clients'
return on R&D investments.

         Patient data must be obtained from the field efficiently, quickly and
accurately to speed subsequent data entry, management and analysis, and report
writing. PPD Pharmaco reviews data through visits by its field monitors to
investigative sites. Field monitors receive orientation training and routine
updates on changes in federal study regulations and new company SOPs for quality
trial monitoring and reporting. These monitors are equipped with laptop
computers for the purpose of SOP and regulatory information updates as well as
report generation.

         PPD Pharmaco has monitored many clinical trials, including a number of
very large studies. For example, PPD Pharmaco is in its second five-year
contract with the National Institutes of Health ("NIH") to monitor
investigational sites for AIDS treatment related trials sponsored by the NIH.
This project involves approximately 250 investigational sites and total
enrollment of approximately 60,000 patients. PPD Pharmaco has monitored 33,000
patients in 233 protocols since the beginning of the project in 1990. There has
also been over 1,900 pharmacy, regulatory and operational audits at the sites.

         CLINICAL DATA MANAGEMENT AND BIOSTATISTICAL ANALYSIS

         The professionals who manage PPD Pharmaco's data management and
biostatistical analysis operations have extensive pharmaceutical and
biotechnology industry experience in the design and construction of local and
multinational clinical trial databases. PPD Pharmaco provides clients with
assistance in such areas as study design, sample size determination, CRF design
and production, fax based monitoring, database design and construction, New Drug
Application preparation and production (including electronic submissions to the
FDA, known as Computer Assisted New Drug Applications), and FDA presentations
and defense.

         The Company offers data management and biostatistical analysis services
both separately and as part of an integrated drug development program. During
the design of development plans and protocols, PPD Pharmaco offers consulting
services relating to sample size parameters for patient enrollment, development
of data analysis plans and randomization schemes. During clinical trials, PPD
Pharmaco assists in the rapid acquisition of clean and accurate data. Following
completion of the clinical trials, PPD Pharmaco assists in report preparation
and FDA presentations. PPD Pharmaco's biostatisticians may participate with
clients in meetings with the FDA to present and defend biostatistical analyses.
PPD Pharmaco has expertise in electronically capturing and integrating
geographically diverse data. PPD Pharmaco uses SAS(R), Clintrace(TM), Oracle(R),
BBN Clintrial(TM) and other third party software, as specified by clients,
combined with customized programs developed by PPD Pharmaco.

         Performing data management and biostatistical analysis activities in
parallel with other drug development activities where possible can reduce drug
development time. For example, data management personnel work with clinical
program managers and field monitors to continuously enter data, program output
tables and listings, and validate the database so that there is a rapid
progression to final tables, listing preparation and biostatistical analyses.
Similarly, there is a close working relationship with medical writing and
regulatory service personnel.

         TREATMENT INVESTIGATIONAL NEW DRUG APPLICATION

         A treatment Investigational New Drug ("IND") application includes a
procedure to allow patients to receive a new drug not yet approved for a serious
or immediate life-threatening disease, such as AIDS or multiple sclerosis, for
which no comparable or satisfactory therapy is available. This treatment is
provided during the clinical trial phase of development, but outside the
controlled clinical trial. The treatment IND application process has the
advantage of getting a new drug into an expanded patient base early, as well as
allowing earlier publicity about the potential success of the drug. PPD
Pharmaco's involvement in a treatment IND application may range from simply
monitoring the treatment to providing an integrated set of services involving
full investigational site management, data management, biostatistical analysis
and report writing.

         MEDICAL WRITING AND REGULATORY SERVICES

         PPD Pharmaco provides full planning services for product development
including pre-clinical review, CMC consulting and clinical protocol development.
These activities are complemented by report writing, program management and
regulatory services designed to reduce overall development time. Strategic
planning and program management provided over the course of a product
development life-cycle helps to ensure that regulatory dossiers are assembled in
a minimum of time and are focused on obtaining the desired labeling for the
compound. These development services are integrated with PPD Pharmaco's other
services to speed the process consistent with good service and regulatory
compliance.

         PPD Pharmaco maintains a large internal compliance and quality
assurance department to provide in-process monitoring of GCP performance. PPD
Pharmaco also offers these services to clients to assess trials conducted by the
client or another CRO.

         HEALTHCARE ECONOMICS, OUTCOMES AND MARKETING RESEARCH

         PPD Pharmaco offers a number of services in the healthcare economics
area to pharmaceutical and biotechnology companies as well as managed care
payers and providers. These services include prospective and retrospective
clinicoeconomics analysis, quality of life and drug therapy evaluation, large
sample market research, clinical hypothesis testing for product marketing,
enhanced patient, investigator and managed care plan recruiting, managed care
consulting, patient therapeutic support systems and disease management
consulting. This research helps clients demonstrate the value of their products
in cost-sensitive markets without costly delays from designing and implementing
new randomized clinical trials.

         DISCOVERY SCIENCES GROUP

         PPD Discovery consists of SARCO, a combinatorial chemistry company, and
the GSX System, a functional genomics platform technology for target discovery.
GSX is a proprietary whole-cell-based system that facilitates the rapid
identification, validation and functional analysis of novel targets.


                                       11
<PAGE>

         GSX identifies targets for drug discovery by the selective inhibition
of genes responsible for key steps in a disease process. The system is based on
the finding that a gene fragment, when introduced into cells, sometimes
specifically inhibits the function of the whole gene from which the fragment was
obtained. Effective inhibitory fragments are obtained by breaking the DNA
containing the genes of interest into many different random pieces, inserting
these fragments into a population of tester cells and identifying the rare
individual cells that acquire a selected new property as a consequence of the
inhibitory action. Examples of desirable cellular properties that can be
selected include increased resistance to a virus or increased sensitivity to a
drug. The "winning" DNA fragments are then recovered from the selected cells and
analyzed to determine what genes, and thereby targets, they represent.
Activities surrounding the GSX technology are conducted in Research Triangle
Park, North Carolina and Menlo Park, California.

         SARCO is a chemical technology company that provides proprietary
combinatorial chemistry and unique, drug-like small molecule combinatorial
libraries to pharmaceutical, biotechnology, agrochemical and animal health
industries. SARCO's core expertise includes the rapid synthesis of large numbers
of compounds for use in the pre-clinical drug discovery and development process
as well as the chemical optimization of those compounds found to have beneficial
biological activity.

         SARCO is located in the Park Research Center, a high-technology campus
in Research Triangle Park, North Carolina. SARCO's research facility is fully
equipped to perform solid and solution-phase combinatorial chemistry, custom
monomer synthesis and solution-phase medicinal chemistry. SARCO maintains full
analytical and computational capabilities in support of its combinatorial and
medicinal chemistry activities.

         Products include the SARCO base libraries, which are chemical compounds
designed for high throughput biological screening, and the SARCO Focus
Libraries, which are custom designed chemical libraries provided exclusively to
a client. Services include research collaborations and partnerships with
research-based discovery companies. These collaborations and partnerships are
typically structured for a fixed period of time or around discrete client
projects.

         Clients and Marketing

         The Company's Life Sciences Group provides services primarily to
pharmaceutical and biotechnology companies. For the year ended December 31,
1998, approximately 87% of the Company's Life Sciences Group's net revenue was
attributable to clinical services and 13.0% to laboratory services. For the year
ended December 31, 1998, net revenue of the Life Sciences Group was derived
approximately as follows:

                                                            Percentage of
         Source                                               Net Revenue
         ------                                               -----------
         Pharmaceutical                                            82.05%
         Biotechnology                                              7.97
         Government                                                 1.92
         Other                                                      8.06

         During 1998, the Company provided services to 40 of the top 50
pharmaceutical companies in the world as ranked by 1997 healthcare research and
development spending.

         The Company provides services to the pharmaceutical and biotechnology
industries and its revenue is highly dependent on expenditures on research and
development by clients in these industries. Accordingly, the Company's
operations could be materially and adversely affected by general economic
downturns in these industries, the current trend toward consolidation in these
industries or other factors resulting in a decrease in research and development
expenditures. Furthermore, the Company has benefited to date from the increasing
tendency of pharmaceutical and biotechnology companies to outsource large
clinical research projects. Should this trend be reversed, the revenue of the
Company could be materially and adversely affected. The Company believes that
concentration of business among certain large customers is not uncommon in the
CRO industry. The Company has experienced such concentration in the past and may
experience such concentration in the future. However, during 1998 and 1997, no
single client contributed more than 10% of the Company's total net revenue. In
1998, the Company's ten largest clients accounted for approximately 39.5% of the
Company's total net revenue and approximately 24% of the Company's total 1998
net revenue was derived from clients located outside the U.S., in particular in
Europe and Japan.


                                       12

         Contractual Arrangements

         Many of PPD Pharmaco's contracts are fixed price, with some variable
components, and range in duration from a few months to several years. In other
contracts, PPD Pharmaco is paid based on applying agreed upon hourly rates to
hours worked. Generally, for multi-year contracts involving clinical trials, a
portion of the contract fee is paid at the time the trial is initiated, with the
balance of the contract fee payable in installments over the trial duration. The
installment payments are typically performance-based, relating payment to
pre-established events or milestones, such as investigator recruitment, patient
enrollment or database delivery. For fixed-price contracts, PPD Pharmaco bears
the risk of cost overruns, but benefits if costs are lower than anticipated.
Underpricing of such contracts or significant cost overruns could have a
material adverse effect on the Company. Most of PPD Pharmaco's contracts for the
provision of its services, including contracts with government agencies, are
terminable by the client upon 30- to 90-days' notice under certain
circumstances, including the client's unilateral decision to terminate the
development of the product or end the study. Contracts may be terminated for a
variety of reasons, including the failure of a product to satisfy safety
requirements, unexpected or undesired results of the product, the client's
decision to forego a particular study, or insufficient patient enrollment or
investigator recruitment. Although the contracts typically require payment of
certain fees for winding down the study and, in some cases, a termination fee,
the loss of a single large contract or of multiple contracts could materially
and adversely affect the Company.

Backlog

         Backlog consists of anticipated net revenue from letters of intent,
verbal commitments, and contracts that have not been completed. Net revenue is
defined as professional fee income (gross revenue) less reimbursed costs,
consisting principally of investigator fees and travel. Once contracted work
begins, net revenue is recognized over the life of the contract. In certain
cases, PPD Pharmaco begins work for a client before a contract is signed. The
backlog of the Life Sciences Group for the services described above under
written agreements, including signed letters of intent, was $291.7 million in
net revenue at December 31, 1998, compared to $205.7 million in net revenue at
December 31, 1997.

         PPD Pharmaco believes that its backlog as of any date is not
necessarily a meaningful predictor of future results, because backlog can be
affected by a number of factors, including variable size and duration of
contracts, many of which are performed over several years. Additionally,
contracts generally are subject to early termination by the client or delay for
many reasons, including unexpected test results. Moreover, the scope of a
contract can change during the course of a study. There can be no assurances
that PPD Pharmaco will be able to fully realize all of its backlog as net
revenue.

Competition

         The CRO industry consists of several hundred small, limited-service
providers, several medium-sized CROs and a few full-service global drug
development companies. The CRO industry is consolidating and, in recent years, a
few large, full-service competitors have emerged. This trend of industry
consolidation will likely result in greater competition among the larger CROs
for clients and acquisition candidates. PPD Pharmaco's large competitors include
Covance, Inc., Kendle International, Inc., Parexel International Corporation,
IBAH, ICON, Phoenix International, AAI and Quintiles Transnational Corporation.
PPD Pharmaco also competes against certain medium-sized companies, in-house
research and development departments of pharmaceutical and biotechnology
companies, as well as universities and teaching hospitals. In addition, the CRO
industry has few barriers to entry. Newer, smaller entities may compete
aggressively against larger CROs for clients. Furthermore, the CRO industry has
attracted the attention of the investment community, which could lead to
increased competition by increasing the availability of financial resources for
CROs. Increased competition may lead to price and other forms of competition
that may adversely affect PPD Pharmaco's operating results.

         CROs compete on the basis of several factors, including reputation for
on-time quality performance, expertise and experience in specific therapeutic
areas, scope of service offerings, strengths in various geographic markets,
technological expertise and systems, ability to acquire, process, analyze and
report data in a time-saving accurate manner, ability to manage large-scale
clinical trials both domestically and internationally, expertise and experience
in healthcare economics and client communication. Although there can be no
assurance that it will continue to do so, the Company believes that it competes
favorably in these areas.

         PPD Informatic's competitors for its packaged software include major
vendors of software used in pharmaceutical applications, such as Domain
Solutions, Oracle and SAS, as well as a variety of smaller, specialized software
companies. Competitors for PPD Informatic's application development services
include major consulting companies with pharmaceutical industry groups (e.g.,
Andersen Consulting, EDS, PricewaterhouseCoopers) and smaller companies with a
pharmaceutical industry focus (e.g. DataCeutics, Netforce, ISCG).

         The outsource chemistry research industry consists of several dominant
providers and numerous smaller niche companies. SARCO faces significant
competition from these companies as well as competition from research teams
funded internally by pharmaceutical and biotechnology companies. While the trend
to outsource research is increasing, the vast majority of research spending by
these companies is for their own internal research personnel.

         SARCO competes principally on the basis of reputation, scientific and
technical expertise, experience and qualifications of professional staff,
quality of services, and ability to delivery quality products to the client's
specifications. As such, SARCO's ability to attract and retain qualified
technical personnel is a key component in its ability to successfully compete in
the outsource contract research market.

Potential Liability and Insurance

         Clinical research services involve the testing of new drugs on human
volunteers pursuant to a study protocol. Such testing exposes the Company to the
risk of liability for personal injury or death to patients resulting from, among
other things, possible unforeseen adverse side effects or improper
administration of the new drug. Many of these patients are already seriously ill
and are at risk of further illness or death. The Company attempts to manage its
risk of liability for personal injury or death to patients from administration
of products under study through measures such as contractual indemnification
provisions with clients and through insurance maintained by clients. The
contractual indemnifications generally do not protect the Company against
certain of its own actions, such as negligence. The contractual arrangements are
subject to negotiation with clients and the terms and scope of such
indemnification vary from client to client and from trial to trial. Although
most of PPD Pharmaco's clients are large, well-capitalized companies, the
financial performance of these indemnities is not secured. Therefore, the
Company bears the risk that the indemnifying party may refuse, or not have the
financial ability, to fulfill its indemnification obligations. The Company could
be materially and adversely affected if it were required to pay damages or incur
defense costs in connection with a claim that is beyond the scope of an
indemnity provision or beyond the scope or level of insurance coverage or where
the indemnifying party does not fulfill its indemnification obligations. Until
September 1996, the Company did not maintain liability insurance with respect to
these risks. The Company currently maintains professional liability insurance
coverage of up to $5.0 million per claim, with an annual aggregate policy limit
of $5.0 million. Liability claims might exceed the limits of such coverage and
such insurance might not continue to be available on commercially reasonable
terms or at all.

Government Regulation

         The laboratory services performed by PPD Pharmaco are subject to
various regulatory requirements designed to ensure the quality and integrity of
the testing process. The industry standards for conducting laboratory testing
are embodied in the regulations for Good Laboratory Practice ("GLP") and Good
Manufacturing Practice ("GMP"). GLP and GMP have been adopted by the FDA, by the
Department of Health in the United Kingdom and by similar regulatory authorities
in other parts of the world. GLP and GMP stipulate requirements for facilities,
equipment and professional staff. The regulations require standardization
procedures for studies, for recording and reporting data, and for retaining
appropriate records. To help ensure compliance, PPD Pharmaco has established
quality assurance controls at its laboratory facilities that monitor ongoing
compliance with GLP and GMP regulations by auditing test data and conducting
regular inspections of testing procedures.

         The industry standard for the conduct of clinical research and
development studies is embodied in the ICH regulations for GCP. As a matter of
practice, the FDA and many other regulatory authorities require that test
results submitted to such authorities be based on studies conducted in
accordance with GCP. These regulations include (i) complying with regulations
governing the selection of qualified investigators, (ii) obtaining specific
written commitments from the investigators, (iii) verifying that informed
consent is obtained from patients, (iv) monitoring the validity and accuracy of
data, (v) verifying drug or device accountability, and (vi) instructing
investigators to maintain records and reports. For specified periods PPD
Pharmaco must also maintain reports for each study for inspection by the study
sponsor and governmental authorities during audits. Noncompliance with GCP can
result in the disqualification of data collected during the clinical trial.

         PPD Pharmaco's Global Standard Operating Procedures ("SOPs") are
written in accordance with the Code of Federal Regulations and ICH guidelines
agreed upon by the United States, certain European and the Japanese governments.
This enables our work to be conducted locally, regionally and globally to
standards that exceed all currently applicable regulatory requirements.


                                       14
<PAGE>

         PPD Pharmaco's business depends on the continued government regulation
of the drug development process, especially in the United States. Changes in
regulation, including a relaxation in regulatory requirements or the
introduction of simplified drug approval procedures, could materially and
adversely affect the demand for the services offered by the Company.

         The failure on the part of PPD Pharmaco to comply with applicable
regulations could result in the termination of ongoing research or the
disqualification of data for submission to regulatory authorities. Furthermore,
the issuance of a notice of finding by a governmental authority against either
PPD Pharmaco or its clients based upon a material violation by the Company of
GCP, GLP or GMP requirements could materially and adversely affect the Company.

Intellectual Property

         The Company has rights in certain trademarks such as PPD(TM), PPD
Pharmaco(R), The Power of Selection(TM), CLASSIFYTM, RESOLVETM, CROSS GRAPHS(R),
TABLETRANS(R) and others. In addition, the Company holds certain licensing
privileges related to the GSX technology.

         PPD Pharmaco also has developed certain computer software and
technically derived procedures intended to maximize the quality and efficiency
of its services. In addition to its rights to certain intellectual property, the
Company believes that other factors such as the technical expertise, knowledge,
ability and experience of the Company's professionals provide significant
benefits to its clients.

Employees

         At December 31, 1998, the Company had approximately 3,100 full-time
equivalent employees, of whom 2,500 were employed in the Life Sciences Group,
340 were employed in the Environmental Sciences Group (which was sold in January
1999), 50 were employed in the Discovery Sciences Group and the remainder were
in the Company's corporate headquarters. Of the Company's employees,
approximately 130 hold Ph.D., M.D., Pharm.D. or D.V.M. degrees and approximately
390 hold other masters or other postgraduate degrees. None of the Company's
employees is represented by a labor union or is subject to a collective
bargaining agreement. The Company believes that its relations with its employees
are good.

         The Company's performance depends on its ability to attract and retain
qualified professional, scientific and technical staff. The level of competition
among employers for such skilled personnel is high. The Company believes that
its employee benefit plans enhance employee morale, professional commitment and
work productivity and provide an incentive for employees to remain with the
Company. The Company, like many of its competitors, also relies on a number of
key executives. The loss of services of any of the Company's key executives
could have a material and adverse effect on the Company. While to date the
Company has not experienced any significant problems in attracting or retaining
qualified staff, it might in the future.

1.   Following termination of its status as an S corporation prior to completion
     of its initial public offering in January 1996, PPD became subject to
     federal and state income taxes. The income tax data for each of the years
     ended December 31, 1995 and 1994 reflects the application of corporate
     income taxes to PPD's net income at the statutory combined federal and
     state tax rate as if the termination of PPD's S Corporation status had
     occurred on January 1, 1994.

2.   Weighted average shares outstanding for each of the years ended December
     31, 1995 and 1994 assumes the occurrence of events pursuant to PPD's
     initial public offering and the issuance of sufficient shares at $18.00 per
     share to provide net proceeds, after aggregate offering expenses and
     underwriting discounts, to repay the $5.5 million debt incurred by PPD in
     making the final S corporation distribution.

3.   The loss from continuing operations for 1995 was affected by (i) the sale
     of APBI's toxicology business, which resulted in a pre-tax loss of $19.3
     million charged against operating income, (ii) a special charge against
     operating income of $5.0 million primarily related to the impairment of
     APBI's available for sale investments and (iii) an increase in APBI's tax
     benefit as a result of the reversal of certain tax liabilities recorded in
     prior years for which it was determined that APBI will not be liable for
     payment.

4.   The net loss for 1996 was affected by $14.8 million of merger costs
     incurred in connection with the acquisition of APBI. After associated tax
     benefits, the impact on net income of such merger costs was $13.0 million.

5.   Revenues are presented net of subcontractor costs. See accompanying
     consolidated statements of operations.

6.   The discontinued operations include the Company's environmental sciences
     segment sold in January 1999 and the writeoff of its remaining investment
     in PACE Incorporated during the fourth quarter of 1995. All prior periods
     have been restated to exclude both of the above operations.

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

         Statements in this Management's Discussion and Analysis that are not
descriptions of historical facts are forward-looking statements within the
meaning of the Private Securities Litigation Reform Act of 1995 reflecting
management's current view with respect to certain future events and financial
performance that are subject to risks and uncertainties. Actual results could
differ materially from those currently anticipated due to a number of factors,
including those set forth herein and in the Company's other SEC filings, and
including, in particular, risks relating to government regulation; dependence on
certain industries; the fixed price nature of contracts; the commencement,
completion or cancellation of large contracts; progress of ongoing contracts;
potential liability associated with the Company's lines of business; dependence
on personnel; management of growth and competition. Since a large percentage of
the Company's operating costs are relatively fixed, variations in the timing and
progress of large contracts can materially affect results.

GENERAL

         During 1998, the Company reported net income of $19.8 million, or $0.85
per share, compared to net income of $9.6 million, or $0.42 per share, during
1997. Excluding gain on sale of business and acquisition related costs, the
Company's net income of $21.0 million was 36.1% higher than prior year net
income, excluding merger and acquisition costs, of $15.5 million.


         Effective January 31, 1999, the Company sold its environmental sciences
segment to Environ Holdings, Inc., a new company formed by the management of
ENVIRON. The Company received as consideration cash of $1.4 million, a four-year
note in the amount of $7.0 million and a 12-year note in the amount of $18.0
million. The Company received an opinion from Lehman Brothers to the effect that
the consideration received is fair from a financial standpoint. The Company will
not recognize a pre-tax gain or loss as a result of the sale of the
environmental sciences segment as the sales price was based on the net assets of
the environmental sciences segment at January 31, 1999. The Company entered into
a three year consulting agreement to provide certain consulting services to
Environ Holdings for a fee of $0.5 million per year.


         In February 1999, the Company formed a joint venture, PPGx, with Axys
Pharmaceuticals, Inc. to pursue the business of pharmacogenomics. The Company
contributed $1.5 million in cash, the net assets of Intek, and assigned the
rights to a certain software license from Axys for an 18.2% ownership interest
in PPGx. Separately, the Company and Axys entered into a software licensing
agreement whereby the Company licensed certain software from Axys in exchange
for a $2.0 million license fee. The Company has received exclusive marketing
rights to PPGx pharmacogenomics products and services and an option to increase
its ownership share of PPGx after the first anniversary of PPGx.


         In February 1999, the Company signed a non-binding letter of intent to
acquire ATP, Inc., a health information services company. ATP provides
customized inbound and outbound telecommunications programs targeting consumers
and health care providers. Under the terms of the letter of intent, the Company
will issue approximately 1 million shares of unregistered common stock, subject
to certain closing adjustments, to the shareholders of ATP in return for their
ATP stock. The transaction is expected to be accounted for as a pooling of
interests.


         In May 1998, the Company created GenuPro, Inc., a subsidiary of PPD
which holds a license to a number of compounds in the genitourinary field which
was purchased from Eli Lilly & Co. in the second quarter of 1998. As a result of
the purchase of these compounds, the Company recorded an acquired in-process
research and development charge of $3.2 million in the second quarter of 1998 as
these compounds were in the initial stage of research and development at the
date the compounds were acquired. The formation of GenuPro, Inc. is an addition
to the Company's Discovery Sciences Group.


         In February 1998, the Company, through its subsidiary Clinix
International Inc., sold substantially all of the assets of the Chicago Center
for Clinical Research ("CCCR"). The selling price was approximately $7.8 million
in the form of $5.3 million in cash and a promissory note for $2.5 million which
will be received over a period of five years. The sale resulted in a gain of
approximately $1.1 million which was recognized as other income during the first
quarter of 1998. As part of the sales agreement, the Company will continue to
provide CCCR with certain clinical and administrative services for an agreed
upon amount through the first quarter of 1999.


                                       22

         In June 1997, the Company moved into a new line of business with the
acquisitions of SARCO and the GSX System. These acquisitions formed the basis of
the Company's Discovery Sciences Group, which focuses on the discovery segment
of the research and development outsourcing market. The Company acquired SARCO
in a transaction accounted for as a pooling of interests. The consideration for
SARCO consisted of 263,158 shares of the Company's common stock. The Company
acquired the GSX System, a functional genomics platform technology, for
approximately $8.7 million in cash.

         In March 1997, the Company acquired Belmont, a software systems
company, in a transaction accounted for as a pooling of interests. The
consideration for Belmont consisted of 502,384 shares of the Company's common
stock. In November 1997, the Company acquired Intek Labs, Inc. ("Intek"), a
pharmacogenetics company, in a transaction accounted for as a pooling of
interests. The consideration for Intek consisted of 399,999 shares of the
Company's common stock.

<PAGE>

         YEAR ENDED DECEMBER 31, 1998 VERSUS YEAR ENDED DECEMBER 31, 1997

         Net revenue increased $48.1 million, or 25.6%, to $235.6 million in
1998 from $187.5 million. The Life Sciences Group's operations accounted for
99.6% of the Company's net revenue for 1998. The Life Sciences Group generated
net revenue of $234.6 million, up $47.4 million, or 25.3%, from last year. The
growth in the Life Sciences Group operations was primarily attributable to an
increase in the size, scope and number of contracts in the global CRO Phase
II-IV division. The Discovery Sciences Group generated net revenue of $0.9
million, up $0.6 million, or 224.1%, from last year. The growth in the Discovery
Sciences operations was primarily attributable to an increase in the number of
contracts in the combinatorial chemistry division. Net revenue is expected to
increase in the Discovery Sciences operations during 1999, however, unless net
revenue from achievement of development milestones is received, the effect of
the segment on the Company's earnings per share should remain relatively
constant.


         Total direct costs increased 25.3% to $121.2 million from $96.8 million
last year and remained relatively constant as a percentage of net revenue at
51.5% for the current year from 51.6% last year. The Life Sciences Group direct
costs decreased as a percentage of related net revenue to 50.1% from 50.7%. This
decrease is principally due to higher utilization of direct labor employees and
a focused effort to control costs. The Discovery Sciences Group direct costs
increased to $3.6 million in 1998 as compared to $1.9 million in 1997. This
increase was due to a full year of operations being recorded in the current year
as opposed to a half-year of operations recorded in 1997. (As discussed
previously, the Discovery Sciences Group was formed in June 1997 with the
acquisitions of SARCO and the GSX System).


         Selling, general and administrative ("SG&A") expenses increased 23.8%
to $77.8 million from $62.8 million in 1997. The increase is primarily
attributable to the investment in additional personnel to support the Company's
expanding operations. As a percentage of net revenue, SG&A expenses decreased
slightly to 33.0% from 33.5% last year.


         Total depreciation and amortization expense of $12.3 million was $1.4
million, or 13.2%, higher than last year. The increase was related to the
Company's growth as well as the ongoing capital investment in the Company's
business. The Company's capital expenditures (excluding the environmental
sciences segment) were $17.6 million in 1998. Computer equipment and software
accounted for approximately 47% of this capital investment, while expanded
capabilities in the Company's labs and Discovery Sciences Group accounted for
approximately 12%.


         The Company recorded an acquired in-process research and development
charge of $3.2 million in 1998 as a result of the purchase of a license to six
genitourinary compounds from Eli Lilly & Co. during the second quarter. The
Company immediately expensed the acquired in-process research and development
costs because the compounds were in the initial phase of research and
development and had no alternative future use. This compares to an acquired
in-process research and development charge of $9.1 million recognized in 1997
related to the acquisition of the GSX System.


         Operating income improved $13.7 million to $21.0 million for the year
ended December 31, 1998, as compared to $7.3 million for the year 1997.
Excluding gain on sale of CCCR, merger and acquisition related costs, the
Company's adjusted operating income of $24.2 million in 1998 was 42.2% higher
than adjusted operating income of $17.0 million in 1997. As a percentage of net
revenue, the yearly operating income of 8.9% represents a dramatic improvement
from 3.9% of net revenue last year.


         Net interest and other income (expense), net, improved $2.1 million,
rising to $3.6 million for the year ended December 31, 1998 from $1.5 million
for the year 1997. Excluding the gain related to the sale of CCCR, net other
income of $2.5 million was $1.0 million higher than the prior year. The
improvement was primarily the result of the covenant not to compete payments of
$0.7 million resulting from the sale of CCCR in the first quarter of 1998. The
Company expects to receive an additional $0.1 million related to the non-compete
agreement in the first quarter of 1999.


         The Company recorded income from discontinued operations, net of income
tax expense, related to its environmental sciences segment, of $4.6 million in
1998, as compared to $4.2 million in 1997. The environmental sciences segment
was sold on January 31, 1999.


                                       24
<PAGE>

         The net income of $19.8 million in 1998 represents an improvement of
$10.2 million over the $9.6 million from 1997. Net income per basic and diluted
share of $0.85 for 1998 compares to $0.42 in 1997. Excluding the impact of the
gain on sale of CCCR and acquisition-related charges in 1998 and the merger and
acquisition-related charges in 1997, the Company's 1998 net income of $21.0
million is 36.1% higher than net income of $15.5 million for 1997.

YEAR ENDED DECEMBER 31, 1997 VERSUS YEAR ENDED DECEMBER 31, 1996

         Net revenue increased $35.2 million, or 23.1%, to $187.5 million in
1997 from $152.3 million. The Life Sciences Group's operations accounted for
99.8% of the Company's net revenue for 1997. The Life Sciences Group generated
net revenue of $187.2 million, up $34.9 million, or 22.9%, as compared to 1996.
The growth in the Life Sciences Group operations was primarily attributable to
an increase in the size, scope and number of contracts in the North America
clinical development and biostatistics business over 1996. The acquisitions of
Belmont and Intek, both completed in 1997, contributed net revenue of $5.7
million for 1997. The acquisitions of SARCO and the GSX System in June 1997
formed the basis for the Company's Discovery Sciences Group which had $0.3
million of net revenue during 1997.


         Total direct costs increased 22.3% to $96.8 million from $79.1 million
last year and remained relatively constant as a percentage of net revenue at
51.6% for 1997 from 51.9% in 1996. The Life Sciences Group direct costs
decreased as a percentage of related net revenue to 50.7% from 51.9%. This
decrease is principally due to higher utilization of direct labor employees and
a focused effort to control costs.


         Selling, general and administrative ("SG&A") expenses increased 13.3%
to $62.8 million from $55.5 million in 1996. SG&A expenses from 1997
acquisitions comprised $2.8 million of the increase. The remaining increase is
primarily attributable to the investment in the Company's business development
and marketing organization and in the area of information technology. Additional
costs in these areas include personnel costs, training and recruitment of highly
qualified individuals. As a percentage of net revenue, SG&A expenses decreased
to 33.5% from 36.4% last year.


         Total depreciation and amortization expense of $10.9 million was $2.0
million, or 22.3%, higher than last year. The increase was related to the
Company's growth as well as the ongoing capital investment in the Company's
business.


         During 1997, the Company recorded merger costs of $0.6 million in
connection with the acquisitions of Belmont, SARCO and Intek. These costs were
primarily cash expenses, such as legal and accounting fees related to pooling
transactions. During 1996, the Company recorded merger costs of $14.8 million.
These costs were primarily cash expenses, such as investment banking fees, legal
and accounting fees, and employee severance as a result of the integration of
the administrative functions of PPD and APBI.


         The Company recorded an acquired in-process research and development
charge of $9.1 million in the second quarter of 1997. These costs were charged
to operations upon the acquisition of the GSX System. The Company hired an
independent consultant to determine the fair value of the acquired in-process
research and development. The purchase price in excess of the net assets of the
GSX System was allocated to acquired in-process research and development costs,
because the technology had no alternative future use and had not reached
technological feasibility at the date of the acquisition.


         Operating income improved $13.3 million to $7.3 million for the year
ended December 31, 1997, as compared to an operating loss of $5.9 million for
the year 1996. Excluding merger and acquisition related costs, the Company's
operating income of $17.0 million in 1997 was 92.4% higher than operating income
(before the impact of merger and acquisition related costs) of $8.8 million in
1996. As a percentage of net revenue, the 1997 operating income of 3.9%
represents a dramatic improvement from the operating loss of 3.9% of net revenue
in 1996.


         The Company recorded income from its discontinued environmental
sciences segment of $4.2 million in 1997, as compared to $2.9 million in 1996.
The increase in income from discontinued operations in 1997 as compared to 1996
was due to the 1997 acquisition of Technical Assessment Systems, Inc.


                                       25
<PAGE>

         The net income of $9.6 million in 1997 represents an improvement of
$13.1 million over the $3.5 million net loss in 1996. Net income per basic and
diluted share of $0.42 for 1997 compares to a net loss per basic and diluted
share of $0.17 in 1996. Excluding the impact of the merger costs and
acquisition-related charges on both years, the Company's 1997 net income of
$15.5 million is 53.6% higher than 1996's net income of $10.1 million. Excluding
these non-recurring charges, net income per diluted share of $0.68 for 1997
compares to $0.47 for 1996 computed on 1.6 million more shares outstanding for
1997.


LIQUIDITY AND CAPITAL RESOURCES


         As of December 31, 1998, the Company had $34.1 million of cash and cash
equivalents on hand. The Company has historically funded its operations and
growth, including acquisitions, with cash flow from operations, borrowings and
through the use of the Company's stock.


         For the year ended December 31, 1998, the Company experienced a net
increase in cash flow from operating activities to $23.6 million as compared to
$11.1 million for the year ended December 31, 1997. The increase in cash flow
from operations is primarily due to an increase in the Company's net revenues
and an increase in operating margins as a percentage of net revenues. For the
1998 period, net income of $19.8 million, depreciation and amortization of $14.2
million and the acquired in-process research and development of $3.2 million
were offset primarily by the net increase of $13.8 million in other assets and
liabilities (which includes a $28.1 million increase in accounts receivable and
unbilled services due to the growth in revenue).


         For the year ended December 31, 1998, the Company's investing
activities used net cash of $11.0 million. Capital expenditures of $19.3
million, cash paid for the acquisition of a license to certain compounds of $3.2
million and $1.8 million in net cash paid for acquisitions were partially offset
by $8.0 million in proceeds from the sale of investments and $5.3 million of net
proceeds received from the sale of CCCR.


         For the year ended December 31, 1998, the Company's financing
activities provided $5.6 million in cash, as net proceeds from stock option
exercises of $7.0 million were partially offset by $1.5 million in repayment of
long-term debt.


         For the year ended December 31, 1997, the Company experienced a net
increase in cash flow from operating activities to $11.1 million as compared to
$0.3 for the year ended December 31, 1996. For the period, net income of $9.6
million, depreciation and amortization of $12.4 million and the acquired
in-process research and development of $9.1 million were offset primarily by the
net decrease of $19.1 million in other assets and liabilities (which includes a
$24.5 million increase in billed and unbilled receivables due to the growth in
revenue), as well as cash disbursements of $7.4 million related to previously
accrued merger expenses.


         For the year ended December 31, 1997, the Company used net cash of
$16.8 million in investing activities, as capital expenditures of $13.6 million
and the cash paid for the acquisition of the GSX technology of $9.1 million were
only partially offset by $6.3 million in cash provided by net maturities of
investments.


         For the year ended December 31, 1997, the Company's financing
activities provided $1.0 million in cash, as net proceeds from stock option
exercises of $2.2 million were partially offset by $1.3 million in net repayment
of long-term debt and $0.4 million in cash used to pay pre-merger distributions
to shareholders of Belmont.


         In June 1998, the Company obtained a $50.0 million revolving credit
facility with First Union National Bank. Interest accrues on amounts borrowed at
a floating rate currently equal to LIBOR plus 0.625% per year. Indebtedness
under the line is unsecured and subject to certain covenants relating to
financial ratios and tangible net worth. The unused portion of the loan is
available to provide working capital and for general corporate purposes. As of
December 31, 1998, the Company had $15.0 million reserved under this facility in
the form of a letter of credit. This credit facility expires in June 2000, at
which time any outstanding balance is due.


                                       26
<PAGE>

         In August 1998, the Company renegotiated a credit facility for $50.0
million with Wachovia Bank, N.A. Interest accrues on amounts borrowed at a
floating rate currently equal to LIBOR plus 0.70% per year. Indebtedness under
the line is unsecured and subject to certain covenants relating to financial
ratios and tangible net worth. The unused portion of the loan is available to
provide working capital and for general corporate purposes. As of December 31,
1998, the Company had $3.3 million outstanding under this facility. This credit
facility expires in March 1999, at which time the outstanding balance is due.
The Company plans to renegotiate this credit facility before its expiration
date.


         The Company expects to continue expanding its operations through
internal growth and strategic acquisitions. The Company expects such activities
will be funded from existing cash, cash flow from operations, borrowings under
its credit facilities and through the use of the Company's stock. The Company
believes that such sources of cash will be sufficient to fund the Company's
current operations for at least the next 12 months. The Company is currently
evaluating a number of acquisitions and other growth opportunities which may
require additional external financing, and the Company may seek to obtain funds
from public or private issuances of equity or debt securities.


YEAR 2000 COMPLIANCE

         The Year 2000 issue is the result of computer programs having been
written using two digits, rather than four, to define the applicable year. As a
result, computer systems and/or software used by many companies in a very wide
variety of applications may experience operating difficulties unless they are
modified or upgraded to adequately process information involving, related to or
dependent upon the four digit field. Significant uncertainty exists concerning
the scope and magnitude of problems associated with the Year 2000.

         The Company recognizes the need to ensure its operations will not be
adversely impacted by Year 2000 failures and has established an internal review
team to address the Year 2000 issue that encompasses operating and
administrative areas of the Company. During the first quarter of 1997, a team of
experienced information technology staff was assigned to work with Company
personnel to identify and resolve significant Year 2000 issues in a timely
manner. In addition, executive management regularly monitors the status of the
Company's Year 2000 remediation plans. The process includes an assessment of
issues and development of remediation plans, execution of those plans and
testing of all technology affected by this issue. In addition, the Company is
engaged in assessing the Year 2000 issue with significant suppliers and clients.

         At December 31, 1998, the assessment process is 95% complete for all
equipment (including computer hardware and software technology) used internally
by the Company as compared to 85% at September 30, 1998. The Company has also
determined that it is unlikely that it will have any material exposure to
contingencies related to the Year 2000 issue in connection with services and
products sold by the Company. Remediation is well underway, with approximately
80% of all systems requiring remediation completed at December 31, 1998 as
compared to 50% at September 30, 1998. All systems, regardless of whether they
require remediation, are being tested to ensure Year 2000 compliance. The
Company has completed testing for Year 2000 compliance as of December 31, 1998
for 89% of our systems as compared to 50% at September 30, 1998. The Company
expects to complete this effort by April 1999. The Company has initiated formal
communications with its significant suppliers in North America and Europe to
determine the extent to which the Company is vulnerable to third party failure
to remediate Year 2000 compliance problems. The Company is in regular
communication with key suppliers and clients and responds promptly to all
requests for information regarding Year 2000 compliance. Based on current
information available, management believes that it will be able to perform all
services and provide all products it currently offers without any material
adverse effects arising from failure to remediate deficiencies arising from Year
2000.
         External and internal costs specifically associated with applying
vendor upgrades, testing and modifying internal use software for Year 2000
compliance are expensed as incurred. The Company pays for Year 2000 expenses
with cash from operating activities. The percentage of the Company's information
technology budget expected to be used for remediation is approximately 11% in
1998 and 5% in 1999. To date, the Company has spent $1.4 million on Year 2000
compliance, and expects to spend an additional $0.2 million to complete the
compliance process. Of the total amount that the Company expects to spend, $1.2
million is attributable to internal labor costs for assessment and testing.
Although internal resources have been dedicated to Year 2000 efforts, work has
been spread across all areas and there has been no material delay in any major
projects.

         The failure to correct a material Year 2000 problem could result in an
interruption in, or a failure of, certain normal business activities or
operations. Such failures could materially and adversely affect the Company's
results of operations, liquidity and financial condition. The Company has
represented to some clients that it intends to be Year 2000 compliant by April
1999. If unexpected issues arise causing delays in the clinical studies being
performed for these clients, the Company will have a specified period of time to
correct those issues. If not corrected, the client can modify or terminate its
contract with the Company. The Company believes that modification or termination
of one or more client contracts represents the most reasonably likely adverse
event which might arise from material Year 2000 compliance failures. Due to the
general uncertainty inherent in the Year 2000 problem, resulting in part from
the uncertainty of the Year 2000 readiness of third-party suppliers and clients,
the Company is unable to determine at this time whether the consequences of Year
2000 failures will have a material impact on its results of operations,
liquidity or financial condition.

         The Company expects to significantly reduce the level of uncertainty
about Year 2000 problems and, in particular, about Year 2000 compliance and
readiness of its key suppliers and clients, as it nears completion of the
inquiry, testing and replacement phase. The Company also believes that its
experienced information technology staff, which has been instrumental in the
Company's Year 2000 compliance efforts, may be able to mitigate many Year 2000
problems. However, the Company will continue to assess and develop contingency
plans for a possible Year 2000 failure as it completes its testing of Year 2000
issues.
         The cost of the Year 2000 compliance project and the time by which the
Company expects to complete its Year 2000 assessment and remediation are
estimates, based on numerous assumptions, including the continued availability
of funding resources and third party modification plans. However, there can be
no guarantee that these estimates are accurate and will be achieved, and actual
results could differ significantly from management's expectations. In addition,
there is no guarantee that the Company's evaluation of the most likely effects
of a material Year 2000 compliance failure is correct, or that its plan to
address such failure will be adequate. In either instance, the effect upon the
Company's financial condition could be material. 

EXCHANGE RATE FLUCTUATIONS AND EXCHANGE CONTROLS

         The vast majority of the Company's contracts are entered into by the
Company's United States or United Kingdom subsidiaries. The contracts entered
into by the United States subsidiaries are almost always denominated in United
States dollars.

         Contracts between the Company's United Kingdom subsidiaries and their
clients are generally denominated in pounds sterling. Substantially all of the
United Kingdom subsidiaries' expenses, such as salaries, services, materials and
supplies, are paid in pounds sterling. However, the Company's consolidated
financial statements are denominated in dollars and, accordingly, changes in the
exchange rate between the pound sterling and the dollar will affect the
translation of such subsidiaries' financial results into dollars for purposes of
reporting the Company's consolidated financial results, and also affect the
amounts in dollars actually received by the Company from such subsidiaries.

         The Company currently participates in only a small number of
transactions involving multiple currencies. In most of those situations,
contractual provisions either limit or reduce the translation risk. Financial
statement translation has not, to date, been material to the Company's balance
sheet. The reasons for this are that the majority of international operations
are located in the United Kingdom, which traditionally has had a relatively
stable currency, and that international operations have not accounted for a
significant portion of total operations (approximately 15%). It is anticipated
that those conditions will persist for at least through December 31, 1999.

         There are no material exchange controls currently in effect in any
country in which the Company's subsidiaries conduct operations on the payment of
dividends or otherwise restricting the transfer of funds outside such countries
by a company resident in such countries. Although the Company performs services
for clients located in a number of foreign jurisdictions, to date, the Company
has not experienced any difficulties in receiving funds remitted from foreign
countries. However, if any such jurisdictions were to impose or modify existing
exchange control restrictions on the remittance of funds to the Company, such
restrictions could have an adverse effect on the Company's business.

POTENTIAL VOLATILITY OF QUARTERLY OPERATING RESULTS AND STOCK PRICE

         The Company's quarterly operating results are subject to volatility due
to such factors as the commencement, completion or cancellation of large
contracts, progress of ongoing contracts, acquisitions, the timing of start-up
expenses for new offices, management of growth, and changes in the mix of
services. Since a large percentage of the Company's operating costs are
relatively fixed, variations in the timing and progress of large contracts can
materially affect quarterly results. To the extent the Company's international
business increases, exchange rate fluctuations and other international business
risks may also influence these results. The Company believes that comparisons of
its quarterly financial results are not necessarily meaningful and should not be
relied upon as an indication of future performance. However, fluctuations in
quarterly results or other factors beyond the Company's control, such as changes
in earnings estimates by analysts, market conditions in the CRO, environmental,
pharmaceutical and biotechnology industries and general economic conditions,
could affect the market price of the Common Stock in a manner unrelated to the
longer-term operating performance of the Company.


ITEM 7A.          QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK


         The Company is exposed to foreign currency risk by virtue of its
international operations. The Company conducts business in several foreign
countries and approximately 15%, 13% and 14% of the Company's net revenues for
the years ended December 31, 1998, 1997 and 1996, respectively, were derived
from the Company's operations outside the United States. Funds generated by each
subsidiary of the Company are generally reinvested in the country where they are
earned. The operations in the United Kingdom have generated more than 45% of the
Company's revenue from foreign operations. Accordingly, some exposure exists to
potentially adverse movements in the pound sterling. The United Kingdom has
traditionally had a relatively stable currency. It is anticipated that those
conditions will persist for at least through December 31, 1999.


         Additionally, the Company's consolidated financial statements are
denominated in U.S. dollars and, accordingly, changes in the exchange rates
between the Company's subsidiaries' local currency and the U.S. dollar will
affect the translation of such subsidiaries' financial results into U.S. dollars
for purposes of reporting the Company's consolidated financial results.
Translation adjustments are reported with accumulated other comprehensive income
(loss) as a separate component of shareholders' equity. Financial statement
translation has not, to date, been material to the Company's balance sheet. Such
adjustments may in the future be material to the Company's financial statements.

The Board of Directors and Shareholders
Pharmaceutical Product Development, Inc. and its Subsidiaries



         In our opinion, the accompanying consolidated balance sheets and the
related consolidated statements of operations, of shareholders' equity and of
cash flows present fairly, in all material respects, the financial position of
Pharmaceutical Product Development, Inc. and its subsidiaries at December 31,
1998 and 1997, and 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 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 provide a reasonable basis for the opinion expressed above.

1.       SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES:

NATURE OF BUSINESS
         Pharmaceutical Product Development, Inc. and its subsidiaries,
collectively (the "Company"), provide a broad range of research and consulting
services in two business segments: life sciences and discovery sciences. Prior
to the divestiture of its environmental sciences segment on January 31, 1999
(see Note 4), the Company also provided environmental sciences services.
Services provided in the life sciences segment include worldwide clinical
research and development of pharmaceutical products and medical devices,
biostatistical analysis and analytical laboratory services. Discovery sciences
services include target identification and validation, compound creation,
screening and compound selection. Environmental sciences services included
assessment and management of chemical and environmental health risk, site
investigation and remediation planning and litigation support. The Company
provides its services under contract to clients in the pharmaceutical, general
chemical, agrochemical, biotechnology and other industries. The environmental
sciences segment also marketed services to clients in the industrial,
manufacturing and oil and gas industries. The Company's life sciences services
are marketed primarily in the United States and Europe. Revenues derived from
the Company's discovery segment are all within the United States. The
environmental sciences segment marketed its services primarily in the United
States and Europe.

PRINCIPLES OF CONSOLIDATION

         The accompanying consolidated financial statements include the accounts
and results of operations of the Company and its wholly-owned subsidiaries. All
significant intercompany balances and transactions have been eliminated in
consolidation.

MERGER COSTS AND SPECIAL CHARGES

         During 1997, the Company recorded merger costs of $600 in connection
with the acquisitions of Belmont Research, Inc., SARCO, Inc., and Intek Labs,
Inc., which were accounted for using the pooling of interests method of
accounting. These costs were primarily transaction expenses related to these
pooling transactions.

         In connection with the acquisition of Applied Bioscience International
Inc. ("APBI") in September 1996, the Company implemented a reorganization plan
under which the Company would eliminate certain positions and close a facility.
The Company recorded merger and reorganization costs related to this acquisition
of $16,100. Included in these costs were transaction costs of $7,100, related
primarily to investment banking, legal and accounting fees. In addition, the
Company recorded $9,000 in accruals for severance, lease termination and certain
other costs. Of the amounts accrued, $3,200 was for severance payments primarily
for administrative personnel.

ACQUIRED IN-PROCESS RESEARCH AND DEVELOPMENT COSTS

         The Company recorded an acquired in-process research and development
charge of $3,200 in the second quarter of 1998 related to the purchase of a
license to six genitourinary compounds from Eli Lilly & Co. The Company
immediately expensed the acquired in-process research and development costs
because these compounds were in the initial phase of research and development
and had no alternative future use.

         The Company acquired the GSX System for $8,700 in cash in June 1997.
Liabilities assumed in this transaction were $832. The purchase price in excess
of the net assets of the GSX System of $9,100 was allocated to acquired
in-process research and development costs and charged to operations at the
acquisition date, as the technology under development by the GSX System had not
reached technological feasibility and had no alternative future use.

1.       SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):

REVENUE RECOGNITION

         The Company records revenues from fixed-price contracts on a
percentage-of-completion basis. Revenues from time-and-material contracts are
recognized as hours are accumulated multiplied by the billable rates for each
contract. Revenues are recorded net of reimbursement received from clients for
pass-through expenses, which generally include subcontractor costs that consist
of investigator fees, travel and certain other contract costs.

         If it is determined that a loss will result from the performance of a
fixed-price contract, the entire amount of the estimated loss is charged against
income in the period in which such determination is made. Clients generally may
terminate a study at any time, which may cause unplanned periods of excess
capacity and reduced revenues and earnings. To offset the effects of early
terminations of significant contracts, the Company attempts to negotiate the
payment of an early termination fee as part of the original contract.

CASH AND CASH EQUIVALENTS

         Cash and cash equivalents consist of unrestricted cash accounts, which
are not subject to withdrawal restrictions or penalties, and all highly liquid
investments with a maturity of three months or less at the date of purchase.

         Supplemental cash flow information consisted of the following:

                                              YEARS ENDED DECEMBER 31,

                                  =========        =========         =========


MARKETABLE SECURITIES
         The Company records its investment in marketable securities in
accordance with Statement of Financial Accounting Standards No. 115, "Accounting
for Certain Investments in Debt and Equity Securities." The classification of
securities is generally determined at the date of purchase. All marketable
securities of the Company have been classified as available-for-sale and have
been reported at fair value with unrealized gains and losses reported in other
comprehensive income. The unrealized net loss on investment in marketable
securities included in other comprehensive income at December 31, 1998 and 1997
totaled $0 and $64, respectively. Gains and losses on sales of investments in
marketable securities, which are computed based on specific identification of
adjusted cost of each security, are included in other income at the time of the
sales.

INVESTIGATOR PAYMENTS
         Billings and payments to investigators are based on predetermined
contractual agreements that may differ from the accrual of the expense.
Investigator expenses are recognized based upon the status of the work completed
as a percentage of the total procedures required under the contract or based on
patient enrollment over the term of the contract. Payments made in excess of the
accrued expenses are classified as investigator advances, and accrued expenses
in excess of amounts paid are classified as payables to investigators in the
consolidated balance sheet. Contracted physician costs are considered a
pass-through expense and are recorded as a reduction to revenues in the
consolidated statements of operations.

1.       SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):

PROPERTY AND EQUIPMENT

         Property and equipment are stated at cost less accumulated depreciation
and amortization. Depreciation is recorded using the straight-line method, based
on estimated useful lives of 20 to 40 years for buildings, five to 12 years for
laboratory equipment, three to five years for computers and related equipment,
and four to 10 years for furniture and equipment. Leasehold improvements are
amortized over the shorter of the respective lives of the leases or the useful
lives of the improvements. Property under capital leases is amortized over the
life of the lease or the service life, whichever is shorter.


INTERNAL USE SOFTWARE


         The Company accounts for internal use software in accordance with the
provisions of AICPA Statement of Position 98-1, "Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use," which allows certain
direct costs and interest costs that are incurred during the application stage
of development to be capitalized and amortized over the useful life of the
software.


GOODWILL


         The excess of the purchase price of the businesses acquired over the
fair value of net tangible assets and identifiable intangibles and acquired
in-process research and development costs at the date of the acquisitions has
been assigned to goodwill. Goodwill is being amortized over periods of 15 to 40
years. As of December 31, 1998 and 1997, accumulated amortization was $4,926 and
$4,383, respectively. The amortization charges for each of the three years ended
December 31, 1998, 1997 and 1996 were $1,235, $1,401 and $950, respectively.


OTHER ASSETS

         Other assets are comprised of investments in certain technology
companies, other intangible assets, a note receivable and net long-term deferred
tax assets. Other intangible assets are being amortized over periods of three to
five years. See Note 8.


REALIZABILITY OF CARRYING VALUE OF LONG-LIVED ASSETS
         The Company is required to review long-lived assets for impairment
whenever events or changes in circumstances indicate that the carrying amount of
an asset may not be recoverable, in accordance with the provisions of Statement
of Financial Accounting Standards No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed Of". Accordingly,
when indicators of impairment are present, the Company evaluates the carrying
value of property, plant and equipment and intangibles, including goodwill, in
relation to the operating performance and estimates of future discounted cash
flows of the underlying business and recognizes an impairment, if necessary, to
state property, equipment and intangibles at their fair value. No such
impairment was necessary during each of the three years ended December 31, 1998,
1997 and 1996.


UNBILLED SERVICES AND UNEARNED INCOME
         In general, prerequisites for billings are established by contractual
provisions, including predetermined payment schedules, the achievement of
contract milestones or submission of appropriate billing detail. Unbilled
services arise when services have been rendered but clients have not been
billed. Similarly, unearned income represents amounts billed in excess of
revenue recognized.

INCOME TAXES

         Income taxes are computed using the asset and liability approach that
requires the recognition of deferred tax assets and liabilities for the expected
future tax consequences of events that have been recognized in the Company's
financial statements or tax returns. In estimating future tax consequences, the
Company generally considers all expected future events other than enactment of
changes in tax law or rates. If it is "more likely than not" that some portion
or all of a deferred tax asset will not be realized, a valuation allowance is
recorded.

                      (IN THOUSANDS, EXCEPT PER SHARE DATA)



1.       SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):

CONCENTRATION OF CREDIT RISK

         Statement of Financial Accounting Standards No. 105, "Disclosure of
Information about Financial Instruments with Off-Balance-Sheet Risk and
Financial Instruments with Concentrations of Credit Risk", requires disclosure
of information about financial instruments with off-balance-sheet risk and
financial instruments with concentrations of credit risk. Financial instruments
which subject the Company to concentrations of credit risk consist principally
of accounts receivable and cash equivalents.

         The Company's clients are primarily pharmaceutical and biotechnology
companies. No single client accounted for more than 10% of the Company's net
revenue in 1998, 1997 or 1996. Concentrations of credit risk with respect to
accounts receivable are limited due to the large number of clients comprising
the Company's client base. Ongoing credit evaluations of customers' financial
condition are performed and, generally, no collateral is required. The Company
maintains reserves for potential credit losses and such losses, in the
aggregate, have not exceeded management's estimates.

         The Company's cash equivalents consist principally of commercial paper.
Certain bank deposits may at times be in excess of the FDIC insurance limit.
Based on the nature of the financial instruments and/or historical realization
of these financial instruments, management believes they bear minimal risk.

TRANSLATION OF FOREIGN FINANCIAL STATEMENTS

         Assets and liabilities of foreign operations, where the functional
currency is the local currency, are translated into U.S. dollars at the rate of
exchange at each reporting date. Income and expenses are translated at the
average rates of exchange prevailing during the month in which a transaction
occurs. Gains or losses from translating foreign currency financial statements
are accumulated in other comprehensive income. The cumulative translation
adjustment included in other comprehensive income at December 31, 1998 and 1997
totaled $78 and $(1,318), respectively. Foreign currency transaction gains and
losses are included in other income.

         Funds generated by each subsidiary of the Company are generally
reinvested in the country where they are earned.

EARNINGS PER SHARE

         The Company adopted Statement of Financial Accounting Standards No.
128, "Earnings Per Share" ("SFAS No. 128"), on December 31, 1997. The
computation of basic income (loss) per share information is based on the
weighted average number of common shares outstanding during the year. The
computation of diluted income (loss) per share information is based on the
weighted average number of common shares outstanding during the year plus the
effects of any dilutive common stock equivalents at year-end. Earnings per share
for all periods presented in the statements of operations conforms to the
provisions of SFAS No. 128.

COMPREHENSIVE INCOME

         The Company adopted Statement of Financial Accounting Standards No.
130, "Reporting Comprehensive Income" ("SFAS No. 130"), effective January 1,
1998. SFAS No. 130 requires the Company to display an amount representing
comprehensive income for the year in a financial statement which is displayed
with the same prominence as other financial statements. The Company has elected
to present this information in the Statements of Shareholders' Equity. Upon
adoption, all prior period data presented was restated to conform to the
provisions of SFAS No. 130.

NEW ACCOUNTING PRONOUNCEMENTS

         The Company adopted Statement of Financial Accounting Standards No.
131, "Disclosures about Segments of an Enterprise and Related Information"
("SFAS No. 131"), on December 31, 1998. SFAS No. 131 requires the Company to
report certain information about operating segments in complete sets of
financial statements and in condensed financial statements of interim periods
issued to shareholders. It also establishes standards for related disclosures
about products and services, geographic areas and major customers. See Notes 17
and 18.

1.       SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED):

         The Company adopted Statement of Financial Accounting Standards No.
132, "Employers' Disclosures about Pensions and Other Postretirement Benefits"
("SFAS No. 132"), on December 31, 1998. SFAS No. 132 standardizes the disclosure
requirements for pensions and other postretirement benefits to the extent
practicable, requires additional information on changes in the benefit
obligations and fair values of plan assets that will facilitate financial
analysis, and eliminates certain disclosures that are no longer useful. See Note
13.

USE OF ESTIMATES

         The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

RECLASSIFICATIONS


         Certain prior year amounts have been reclassified to conform to the
1998 presentation.

2.       ACQUISITIONS:

POOLINGS

         In March 1997, the Company acquired Belmont Research, Inc. ("Belmont").
The consideration for Belmont consisted of 502 shares of the Company's common
stock plus options to purchase approximately 115 shares of Company common stock.
In June 1997, the Company acquired SARCO, Inc. ("SARCO"). The consideration for
SARCO consisted of 263 shares of the Company's common stock. In November 1997,
the Company acquired Intek Labs, Inc. ("Intek"). The consideration for Intek
consisted of 400 shares of the Company's common stock. All three of these
acquisitions were accounted for as pooling of interests transactions. Pro forma
information is not presented nor have the Company's consolidated financial
statements for 1996 been restated to reflect the impact of these acquisitions as
the results of operations of Belmont, SARCO and Intek prior to the dates of the
acquisitions are not material individually or collectively to the Company.

         On September 26, 1996, a wholly-owned subsidiary of the Company was
merged with and into APBI in a transaction accounted for as a pooling of
interests. As a result of the merger, APBI became a wholly-owned subsidiary of
the Company. Under the terms of the merger agreement, APBI shareholders received
0.4054 of a share of the Company's common stock for each APBI share. As a result
of the merger, the Company issued 12,064 shares of its common stock in exchange
for all the outstanding shares of common stock of APBI. Holders of options to
acquire APBI stock had the choice to receive either shares of Company common
stock for the value of the options, or substitute options to acquire Company
common stock. As a result of the APBI option holders' choices, 203 additional
shares of the Company's common stock were issued, and options to purchase 601
shares of the Company's common stock were issued. In accordance with the pooling
of interests method of accounting, the consolidated financial statements are
based on the assumption that the companies were combined for all of 1996 and the
financial statements for 1996 were restated to give effect to the combination.

PURCHASES

         In January 1998, the Company acquired two environmental consulting
businesses for a total of $1,006 in cash and potential for the former owners to
earn an additional amount depending on the profitability of the businesses for a
certain period after the acquisition. In connection with these acquisitions, the
Company recorded approximately $900 in goodwill. Pro forma information is not
presented as the acquired companies' results of operations prior to the dates of
the acquisitions are not material individually or collectively to the Company.

2.       ACQUISITIONS (CONTINUED):

         In January 1997, the Company acquired Technical Assessment Systems,
Inc. ("TAS") for $490 in cash, a note for approximately $300 and the potential
to earn an additional amount depending on TAS's profitability for a certain
period after the acquisition. In connection with the acquisition, the Company
recorded $1,070 in goodwill. In June 1997, the Company acquired the GSX System,
a functional genomics platform technology. The GSX System was purchased for
approximately $8,700 in cash. Liabilities assumed in this transaction were $832.
Pro forma information is not presented as the acquired companies' results of
operations prior to the dates of the acquisitions are not material individually
or collectively to the Company.

         The Company's Life Sciences Group furthered its expansion outside of
the U.S. in 1996 through the acquisitions of Trilife Gesellschaft Fur
Medizinische Entwicklung Verwaltungs GmbH ("Trilife") in Germany, Medisys S.L.
("Medisys") in Spain, Q&Q Suporte A Pesquisa Clinica Ltda. ("Q&Q") in Brazil,
Data Acquisition and Research Limited ("DAR") in Scotland, and Environmental
Assessment Group Limited ("EAG") in England. The consideration for these five
companies consisted of approximately $4,359 in cash and a note for $350. The
Company has paid an additional $1,264 for these acquisitions, due to earnout
clauses in the purchase agreements and amounts due on anniversaries of the
acquisitions during the period from the date of purchase through December 31,
1998. Included in debt on the consolidated balance sheet at December 31, 1998 is
another $340 which will be paid related to the acquisitions of Q&Q and DAR. In
connection with these acquisitions, the Company recorded $6,278 in goodwill. Pro
forma information is not presented as the acquired companies' results of
operations prior to the dates of the acquisitions are not material individually
or collectively to the Company.

3.       SALE OF BUSINESS:

         On February 27, 1998, the Company, through its subsidiary Clinix
International Inc., sold the business and assets of the Chicago Center for
Clinical Research ("CCCR"). The consideration received by the Company for CCCR
totaled approximately $7,785 which was comprised of $5,285 in cash and a
promissory note of $2,500 which will be received over five years. The sale
resulted in a gain of approximately $1,071 that was recognized as other income
during the first quarter of 1998. As part of the sales agreement, the Company
will continue to provide CCCR with certain clinical and administrative services
for an agreed upon amount through the first quarter of 1999.

4.       DISCONTINUED OPERATIONS:

         Effective January 31, 1999, the Company sold its environmental sciences
segment for total consideration of $26,431 in a management buyout. The Company
received as consideration cash of $1,431, a four-year note of $7,000 and a
12-year note of $18,000. The sale resulted in no pre-tax gain or loss as the
sales price was based on the net assets of the environmental sciences segment at
January 31, 1999.

         The consolidated balance sheets at December 31, 1998 and 1997 include
the following assets and liabilities of the environmental sciences segment:

investment in SDI was realized of $174.

         In June 1998, the Company entered into a $50,000 revolving credit
facility with First Union National Bank. Interest accrues on amounts borrowed at
a floating rate equal to the LIBOR plus 0.625% per year. Indebtedness under the
line is unsecured and subject to certain covenants relating to financial ratios
and tangible net worth. The unused portion of the loan is available to provide
working capital and for general corporate purposes. As of December 31, 1998, the
Company had $15,000 reserved in the form of a letter of credit and $35,000
available for borrowings under this facility. This credit facility expires in
June 2000, at which time any outstanding balance is due.

         In August 1998, the Company renegotiated a credit facility for $50,000
with Wachovia Bank, N.A. Interest accrues on amounts borrowed at a floating rate
equal to LIBOR plus 0.70% per year. Indebtedness under the line is unsecured and
subject to certain covenants relating to financial ratios and tangible net
worth. The unused portion of the loan is available to provide working capital
and for general corporate purposes. As of December 31, 1998, the Company had
$3,300 outstanding and $46,700 available for borrowings under this facility.
This credit facility expires in March 1999, at which time the outstanding
balance is due.
         For the years subsequent to December 31, 1998, annual maturities of
long-term debt outstanding are:

10.      LONG-TERM DEBT AND LEASE OBLIGATIONS (CONTINUED):


OPERATING LEASES
         The Company is obligated under noncancellable leases expiring at
various dates through 2011 relating to its operating facilities and certain
equipment. Rental expense for all operating leases, net of sublease income, was
$13,330, $13,492 and $10,334 for the years ended December 31, 1998, 1997 and
1996, respectively.

         The Company completed a sale-leaseback transaction involving owned real
estate in Austin, Texas in November 1995. Total gross proceeds in the
transaction were $12,000, resulting in a pre-tax gain of approximately $2,100.
The gain, which has been deferred, is classified as deferred rent and other in
the accompanying consolidated balance sheets and is being amortized as a
reduction of rent expense on a straight-line basis over the 15-year lease term.
The facilities are leased to the Company with all responsibility of operations
and maintenance residing with the Company.

         Certain facility leases entered into provided for concessions by the
landlords, including payments for leasehold improvements, moving expenses, and
free rent periods. These concessions have been reflected as deferred rent and
other in the accompanying consolidated financial statements. The Company is
recording rent expense on a straight-line basis for these leases.

         Future minimum payments for all operating lease obligations for years
subsequent to December 31, 1998 are as follows:

                    1999                                             $  11,841

         Omitted from the table above are the operating lease obligations
related to the Company's environmental sciences segment which was sold on
January 31, 1999. See Note 4. Future minimum payments related to operating lease
obligations of this segment were $18,593 at December 31, 1998

11.      STOCK PLANS:

STOCK INCENTIVE PROGRAM
         The Company has two stock option plans (the "Plans") under which the
Company may grant options to its employees and directors for up to 2,600 shares
of common stock. Under the Plans, the exercise price of each option equals the
market price of the Company's stock on the date of grant and an option's maximum
term is 10 years. Options are granted upon approval of the Board of Directors
and vest over various periods, as determined by the Board of Directors at the
date of the grant.

         On January 1, 1996, the Company adopted the disclosure requirements of
Statement of Financial Accounting Standards No. 123 ("SFAS No. 123"),
"Accounting for Stock Based Compensation." As permitted by SFAS No. 123, the
Company has chosen to apply Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees", and related interpretations in
accounting for the Plans. Accordingly, no compensation cost has been recognized
for options granted under the Plans. Had compensation cost for the Company's
Plans been determined based on the fair value at the grant dates for awards
under the Plans consistent with the method required by SFAS No. 123, the
Company's net income (loss) and basic and diluted net income (loss) per share
would have been the pro forma amounts indicated below.

</TABLE>
         For the purposes of the pro forma presentation above, the fair value of
each option grant is 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: expected volatility of 60.3%, 58.7% and 49.9%,
respectively; risk-free interest of 5.75%, 6.0% and 6.25%, respectively; and
expected lives of five years. The resulting estimated weighted average fair
value of options granted during 1998, 1997 and 1996 was $13.49, $9.48 and $11.48
per share, respectively. All options granted during the years ended December 31,
1998, 1997 and 1996 were granted with an exercise price equal to the fair value
of the Company's common stock at the grant date The estimated pro forma amounts
above include the compensation cost for the Company's Employee Stock Purchase
Plan based on the fair value of the contributions under this plan consistent
with the method of SFAS No. 123.
         A summary of the status of the Plans as of December 31, 1998, 1997 and
1996, and changes during the years ending on those dates, is presented below:

OTHER STOCK PROGRAMS

         In August 1995, APBI granted a total of 60 restricted stock units
("RSUs") to two executive officers of APBI. The RSUs vested at the time the
average closing price for APBI's common stock equaled or exceeded $10.00 per
share for a period of 10 consecutive trading days. The RSUs vested in July 1996.
The executives were not required to pay any consideration in exchange for the
RSUs. Unearned compensation was amortized to expense over the vesting period of
the RSUs. Compensation expense of $534 related to these RSUs has been recorded
in the accompanying statement of operations for the year ended December 31,
1996.

SAVINGS RELATED STOCK OPTION PLAN

         The Company has a United Kingdom Savings Related Stock Option Plan
under which options are granted to employees who elect to purchase shares of
common stock at the end of a five or seven-year period. Savings are accumulated
through voluntary payroll deductions. The Company contributes a bonus to each
participant's savings account equal to nine monthly contributions at the end of
the five-year period and 18 monthly contributions at the end of the seven-year
period. When the savings period ends, the employee may elect to purchase the
shares using the savings balance, including the bonus; purchase some of the
shares and receive the savings balance in cash; or receive the savings and bonus
in cash. The United Kingdom Plan, as approved by the shareholders, was
implemented by Applied Bioscience International Inc. during 1988. Currently,
employees of the Company's United Kingdom subsidiary, Pharmaco International
Ltd., participate in this plan. Outstanding options of APBI at the time of the
merger were converted in accordance with the exchange ratio provided for in the
merger agreement.

         At December 31, 1998, there were 1 options outstanding at an average
exercise price of $13.72. Of those, 0.9 options were exercisable at December 31,
1998, at an average exercise price of $13.75.

11.      STOCK PLANS (CONTINUED):

EMPLOYEE STOCK PURCHASE PLAN

         The Board of Directors has reserved 500 shares of the Company's common
stock for issuance under the Employee Stock Purchase Plan (the "ESPP"). The ESPP
has two six-month offering periods (each an "Offering Period") annually,
beginning January 1 and July 1, respectively. The first Offering Period under
the ESPP began July 1, 1997. Eligible employees can elect to make deductions
from 1% to 15% of their compensation during each payroll period of an Offering
Period. Special limitations apply to eligible employees who own 5% or more of
the outstanding common stock of the Company. None of the contributions made by
eligible employees to purchase the Company's common stock under the ESPP are tax
deductible to the employees. At the end of an Offering Period, the total payroll
deductions by an eligible employee for that Offering Period will be used to
purchase common stock of the Company at a price equal to 85% of the lesser of
(a) the reported closing price of the Company's common stock for the first day
of the Offering Period, or (b) the reported closing price of the common stock
for the last day of the Offering Period. Only 150 shares will be available for
purchase during each of the Offering Periods beginning with the period
commencing January 1, 1998.

         Employees eligible to participate in the ESPP include employees of the
Company and its United States operating subsidiaries, except those employees who
customarily work less than 20 hours per week or five months in a year. Since the
eligible employee determines both participation in and contributions to the
ESPP, it is not possible to determine the benefits and amounts that would be
received by an eligible participant or group of participants in the future.

         At December 31, 1998, $957 had been contributed to the ESPP relating to
unissued shares. Shares were not issued on December 31, 1998 since the market
had to be closed before a purchase price could be determined. On January 4,
1999, 51 shares were issued. During 1998, $2,971 had been contributed to the
ESPP and 225 shares were issued. The compensation costs for the ESPP as
determined based on the fair value of the contributions under the ESPP,
consistent with the method of SFAS No. 123, was $532 and $196 and is reflected
in the pro forma net income and basic and diluted net income per share for 1998
and 1997, respectively as disclosed above.

         A valuation allowance was recorded against the foreign net operating
loss carryforwards because there is a significant uncertainty that the deferred
tax assets will be realized. In addition, there is an $11,000 gross capital loss
carryforward, which the Company has written off against the valuation allowance
as the Company does not expect to realize this.

12.      INCOME TAXES (CONTINUED):

         The cumulative amount of undistributed earnings of foreign subsidiaries
for which the Company has not provided U.S. income taxes at December 31, 1998
was $1,223. No provision has been made for the additional taxes that would
result from the distribution of earnings of foreign subsidiaries since such
earnings have been permanently reinvested in the foreign operations.

         During 1997, the Company utilized all U.S. net operating loss
carryforwards and alternative minimum tax credit carryforwards.


13.      EMPLOYEE SAVINGS AND PENSION PLANS:

SAVINGS PLANS

         The Company provides a 401(k) Retirement Savings Plan to its U.S.
employees. The Company matches 50% of an employee's savings up to 6% of pay, and
these contributions vest ratably over a four-year period. Company matching
contributions for all employees for each of the three years ended December 31,
1998, 1997 and 1996 were $2,201, $1,945 and $1,483, respectively.

PENSION PLANS

         Pension costs and related disclosures are determined under the
provisions of Statement of Financial Accounting Standards No. 132, "Employers'
Disclosures about Pensions and other Postretirement Benefits," which was adopted
by the Company in 1998. There was no impact on the Company's financial statement
balances as a result of the adoption of this pronouncement.

         The Company has a separate contributory defined benefit plan (the "U.K.
Plan") for its qualifying United Kingdom employees and directors employed by the
Company's U.K. subsidiaries. The benefits for the U.K. Plan are based primarily
on years of service and average pay at retirement. Plan assets consist
principally of investments managed in a mixed fund.

     Pension costs for the U.K. Plan included the following components:

</TABLE>

         Prior to January 31, 1999, the Company maintained the APBI
Environmental Sciences Group, Inc. Pension Plan (the "Pension Plan"), a
tax-qualified, defined-contribution money-purchase pension plan, for the benefit
of its eligible ENVIRON employees. ENVIRON is required to make annual
contributions to the Pension Plan in an amount equal to the sum of 3.75% of each
eligible employee's total compensation, plus 3.75% of the portion of such
employee's compensation in excess of the Social Security wage base. Participants
vest in 20% of their account balances after two years of service and 20% per
year until they are fully vested. The annual pension expense of the Pension Plan
for the three years ended December 31, 1998, 1997 and 1996 was $697, $638 and
$620, respectively. As of December 31, 1998 and 1997, accrued pension cost,
included in other accrued expenses, was $651 and $701, respectively.

         Effective January 1, 1994, APBI Environmental Sciences Group, Inc.
established the ENVIRON Supplemental Executive Retirement Plan. This plan is
nonqualified and provides certain key employees defined-contribution benefits
that supplement those provided by the Pension Plan. Company contributions to
this plan in 1998, 1997 and 1996 were $35, $35 and $39, respectively.

         The Pension Plan and the ENVIRON Supplemental Executive Retirement Plan
became the responsibility of the purchaser of the environmental services segment
on January 31, 1999.

14.      COMMITMENTS AND CONTINGENCIES:

         The Company currently maintains liability insurance on a "claims made"
basis for professional acts, errors and omissions. As of December 31, 1998, this
coverage included two policies. One policy is for the Life and Discovery
Sciences Groups with a self-insured retention per claim of $250 and one is for
the environmental sciences segment with a $500 self-insured retention per claim.
As of December 31, 1998 and 1997 there are no open claims related to these
coverages.

         The Company currently is self-insured for group health for employees
located within the United States. The Company maintains insurance on a "claims
made" basis, up to a maximum of $100 per occurrence. As of December 31, 1998 and
1997 the Company maintained a reserve of approximately $1,500 and $1,300,
respectively, included in other accrued expenses on the consolidated balance
sheets to cover estimated open claims.

         In the normal course of business, the Company is a party to various
claims and legal proceedings. The Company records a reserve for these matters
when an adverse outcome is probable and the amount of the potential liability is
reasonably estimable. Although the ultimate outcome of these matters is
currently not determinable, management of the Company, after consultation with
legal counsel, does not believe that the resolution of these matters will have a
material effect upon the Company's financial condition or results of operations
for an interim or annual period.


15.      RELATED PARTY TRANSACTIONS:
         Several of the Company's shareholders collectively own 14.6% of LOI
Building, Inc. ("LOI"), which leased operating facilities to the Company through
November 1996. Rent paid to LOI for the year ended December 31, 1996 totaled
$402.

         One of the members of the Company's Board of Directors (who was a
member of APBI's Board of Directors prior to the Company's acquisition of APBI)
is Vice Chairman at Lehman Brothers. Lehman Brothers acted as APBI's investment
banker for APBI's acquisition by the Company. For those investment-banking
services, Lehman Brothers earned $3,059 in 1996.

         The Company is related through common ownership with E.M. Associates,
Inc., which provides investigative board services to the Company. The Company
had transactions with E.M. Associates, Inc. of $37 and $66 in expenses for the
years ended December 31, 1997 and 1996, respectively. There were no transactions
with E.M. Associates during the year ended December 31, 1998.

         The Company paid legal fees in 1996 of approximately $333 to a firm,
which had a partner who became General Counsel of the Company in 1996. At the
time this individual became the Company's General Counsel, this individual
disposed of all of his interest in the law firm.

16.      FAIR VALUE OF FINANCIAL INSTRUMENTS:

         The following methods and assumptions were used to estimate the fair
value of each class of financial instruments for which it is practicable to
estimate that value:

CURRENT ASSETS AND CURRENT LIABILITIES

         The carrying amount approximates fair value because of the short
maturity of those instruments.

INVESTMENT IN DAS

         The Company's investment in DAS is recorded at $1,500 at December 31,
1998. The Company's investment in DAS is valued based on the cost method as the
preferred stock of DAS is not tradeable and does not exceed estimated net
realizable value.

                      (IN THOUSANDS, EXCEPT PER SHARE DATA)


16.      FAIR VALUE OF FINANCIAL INSTRUMENTS (CONTINUED):

INVESTMENT IN SDI

         The Company's investment in SDI was recorded at $1,161 compared to the
market price $1,608 as quoted on the National Market System of the National
Association of Securities Dealers Automated Quotation System at December 31,
1997. At December 31, 1997, this investment was not valued at the market price
due to the purchase options outstanding at the exercise price of $1.625 per
share for all shares of SDI which the Company owned. The Company received $1,161
in March 1998 when all the options were exercised.

LONG-TERM DEBT

         The fair value of the Company's long-term debt is estimated based on
the quoted market prices for the same or similar issues or on the current rates
offered to the Company for debt of the same remaining maturities. Fair value
approximates the carrying amount as the Company's debt instruments bear interest
based on variable rates.

LETTERS OF CREDIT

         The Company utilizes letters of credit to back certain guarantees and
insurance policies. The letters of credit reflect fair value as a condition of
their underlying purpose and are subject to fees competitively determined in the
market place.

17.      BUSINESS SEGMENT DATA:

         During 1998 and 1997, the Company operated in three business segments -
life sciences, environmental sciences and discovery sciences. The Company sold
its environmental sciences segment in January 1999 (see Note 4). Prior to 1997,
the Company operated in two segments - life sciences and environmental sciences.
Accordingly, the income statements have been restated to conform to the
provisions of APB 30, "Reporting the Results of Operations - Reporting the
Effects of Disposal of a Segment of a Business, and Extraordinary, Unusual, and
Infrequently Occurring Events and Operations". The consolidated balance sheets
and cash flows have not been restated to exclude the assets, liabilities and
cash flows of the environmental sciences segment.

17.      BUSINESS SEGMENT DATA (CONTINUED):


         Revenues by principal business segment are separately stated in the
consolidated financial statements. Merger costs and acquired in-process research
and development costs incurred in 1998, 1997 and 1996 of $3,163, $9,670 and
$14,773, respectively, were not allocated to the Company's business segments and
are shown separately for purposes of business segment analysis. Income taxes are
allocated evenly to each division for purposes of business segment analysis.
Income (loss) from operations, net income, depreciation and amortization,
identifiable assets and capital expenditures by principal business segment were

20.      SUBSEQUENT EVENTS:

         On January 31, 1999, the Company sold its environmental sciences
segment. See Note 4.

         In February 1999, the Company formed a joint venture, PPGx, with Axys
Pharmaceuticals, Inc. to pursue the business of pharmacogenomics. The Company
contributed $1,500 in cash, the net assets of Intek, and assigned the rights to
a certain software license from Axys for an 18.2% ownership interest in PPGx.
Separately, the Company and Axys entered into a software licensing agreement
whereby the Company licensed certain software, from Axys in exchange for a
$2,000 license fee. The Company has received exclusive marketing rights to PPGx
pharmacogenomics products and services and an option to increase its ownership
share of PPGx after the first anniversary of the forming of PPGx.

         In February 1999, the Company signed a non-binding letter of intent to
acquire ATP, Inc., a health information services company. ATP provides
customized inbound and outbound telecommunications programs targeting consumers
and health care providers. Under the terms of the letter of intent, the Company
will issue approximately 1,000 shares of its unregistered common stock, subject
to certain closing adjustments, to the shareholders of ATP in return for their
ATP stock. The transaction will be accounted for as a pooling of interests.

                                 LEASE AGREEMENT

              THIS LEASE AGREEMENT (the "Lease"), is made and entered into as of
the 16th day of December, 1998, by and between WEEKS REALTY, L.P., a Georgia
limited partnership authorized to do business in North Carolina as WEEKS REALTY
LIMITED PARTNERSHIP (the "Landlord"), and PPD PHARMACO, INC., a Texas
corporation (the "Tenant").

                              W I T N E S S E T H:

              1.      PREMISES AND TERM.

              (a) PREMISES. In consideration of the obligation of Tenant to pay
         rent as herein provided, and in consideration of the other terms,
         provisions and covenants hereof, Landlord hereby leases to Tenant and
         Tenant hereby leases from Landlord, certain premises to be comprised of
         approximately 61,380 rentable square feet (the "Premises") in a
         building to be constructed by Landlord (the "Building") and situated on
         certain land (the "Land") in Morrisville, the County of Wake, State of
         North Carolina, more particularly described on Exhibit A, attached
         hereto and incorporated herein by reference, together with all rights,
         privileges, easements, appurtenances and immunities belonging to or in
         any way pertaining to the Premises.

                  A floor plan of the Building and the Premises shall be
         attached hereto and made a part hereof as Exhibit B. The measurement of
         the Premises shall be conducted in accordance with BOMA standards, 1996
         edition, currently applicable for a Class A office building comparable
         to the Building. Any upfit performed by Landlord to prepare the
         Premises for occupancy by Tenant shall be conducted in a good and
         workmanlike manner and in accordance with all laws, statutes, and
         regulations, and Landlord shall warrant the construction of the
         improvements for a period of one year from the Commencement Date. The
         taking of possession by Tenant shall be deemed conclusively to
         establish that each portion of the Premises and any improvements
         thereto are in good and satisfactory condition as of the date Tenant
         commenced occupancy of that portion of the Premises, except for latent
         defects and punchlist items. Tenant and Landlord shall complete a
         punchlist of items requiring repair that are the responsibility of
         Landlord within thirty (30) days of the Commencement Date. Tenant
         further acknowledges that no representations as to the repair of the
         Premises, nor promises to alter, remodel or improve the Premises have
         been made by Landlord unless such representations or promises are
         expressly set forth in this Lease. Within five days of the Commencement
         Date, Tenant shall, upon demand of Landlord, execute and deliver to
         Landlord a letter of acceptance of delivery of the Premises,
         acknowledging the Commencement Date.

                  All construction of the Premises shall be performed by
         Landlord in accordance with the schedule, plans and specifications for
         the Premises (herein referred to collectively as the "Plans") which
         Plans are subject to the mutual and reasonable approval of Landlord and
         Tenant, a preliminary copy of which is attached hereto and made a part
         hereof as Exhibit C. Construction of the Premises shall proceed in
         accordance with the

<PAGE>

         Building Design and Construction Schedule attached hereto and made a
         part hereof as Exhibit C-1. The components of the Shell Building shall
         be as set forth in Exhibit C-2, attached hereto and made a part hereof.
         The components of the Building Upfit shall be as set forth in Exhibit
         C-3, attached hereto and made a part hereof.

                  Tenant shall review the Plans to provide its input with
         respect to all aspects of the Plans, including, but not limited to, the
         specific needs of Tenant with respect to Heating, Ventilation and Air
         Conditioning and other Building systems, and Landlord shall act
         reasonably to accommodate the specific needs of Tenant with respect to
         the Building systems.

                  Notwithstanding the above, Landlord and Tenant agree that a
         formal construction schedule and final Construction Drawings and
         Specifications, upon the completion of such documents by Landlord,
         Landlord's architectural and engineering service providers, and other
         such parties and further subject to the mutual and reasonable approval
         of such documents by Landlord and Tenant, will replace the contents of
         Exhibit C for purposes of controlling the actual construction of the
         Premises; and such formal construction schedule and final Construction
         Drawings and Specifications shall replace Exhibit C by means of a lease
         amendment between Landlord and Tenant.

                  The base rent delineated in Paragraph 2(a) includes the costs
         of the Shell Building, currently estimated to be Ninety-Four and 35/100
         Dollars ($94.35) per rentable square foot of the Premises (the "Shell
         Allowance"). Should the actual costs of the Shell Building (together
         with the reduced or increased financing costs and commissions of the
         Landlord) be different than the Shell Allowance, the base rent due
         hereunder shall be increased or decreased accordingly by multiplying
         the difference between the actual cost thereof and the Shell Allowance
         by a factor of Ten and 85/100 Percent (10.85%), as reasonably
         determined by Landlord.

                  The base rent delineated in Paragraph 2(a) also includes a
         contribution by the Landlord of Ninety-Two and 14/100 Dollars ($92.14)
         per rentable square foot of the Premises to be applied to the Building
         upfit, as set forth in Exhibit C-2 (the "Upfit Allowance"). Further,
         Landlord has agreed to permit Tenant to increase the Upfit Allowance by
         up to an additional Twelve and 86/100 Dollars ($12.86) per Rentable
         Square Foot of the Premises to satisfy Tenant's interior finish
         requirements, as reasonably approved by Landlord (the Additional Upfit
         Allowance"). At the option of Tenant, any portion or all of the
         Additional Upfit Allowance used by Tenant to complete the upfit shall
         be amortized over the term of the Lease with interest at the rate of
         eleven percent (11%) per annum and repaid by Tenant in equal monthly
         installments together with its payment of base rent hereunder.

                  Should for any reason the upfit costs for the Premises be
         greater than a total of One Hundred Five and NO/100 Dollars ($105.00)
         per rentable square foot (the "Maximum Upfit Allowance"), such excess
         (the "Excess") shall be borne by Tenant and payable by Tenant to
         Landlord within thirty (30) days of demand by Landlord to Tenant.
         Failure by Tenant to pay the Excess upon demand as aforesaid is an
         event of default


                                       2
<PAGE>

         hereunder and, in addition to all other remedies available to Landlord
         at law, or in equity for such event of default, Landlord may recover
         from Tenant the cost it incurs in preparing the Premises for another
         tenant.

                  Should the upfit costs for the Premises be less than the Upfit
         Allowance, Tenant shall be allowed to upgrade the improvements to the
         Premises, as reasonably approved by Landlord, to fully utilize the
         entire Upfit Allowance; or Tenant may elect to have Landlord apply the
         unused Upfit Allowance (together with the reduced financing costs and
         commissions of Landlord), multiplied by the amortization constant for
         eleven percent (11%) per annum to reduce the base rent due hereunder,
         proportionately over the entire Lease Term, all as reasonably
         determined by Landlord and Tenant.

                  Additionally, in the event that Tenant shall not utilize all
         the Upfit Allowance or all or any part of the Additional Upfit
         Allowance, Tenant shall have the right to apply such unused monies
         towards the costs of upfitting the Premises subsequent to completion of
         the initial improvements ("Deferred Allowance") up to the Maximum Upfit
         Allowance, subject to mutual and reasonable approval of plans and
         specifications for such improvements by Landlord and Tenant. Tenant's
         right to the Deferred Allowance shall expire at the end of the second
         year of the term of the Lease and Landlord shall have no further
         obligation to provide any improvement allowances of any kind during the
         term of the Lease unless stated otherwise in this Lease. Any Deferred
         Allowance used by Tenant shall be amortized over the term of the Lease
         remaining at the time of completion of such improvements, with interest
         at the rate of eleven percent (11%) per annum (the "Amortization
         Constant"), and repaid by Tenant in equal monthly installments together
         with its payment of base rent hereunder.

              Landlord shall act reasonably to allow Tenant reasonable access to
         the Premises at least thirty days prior to the Commencement Date to
         install its furniture, telephone and computer systems, and other
         special Building systems. Tenant covenants and agrees to conduct its
         actions in such a manner to not disturb the preparation by Landlord of
         the Premises for occupancy by Tenant. Upon the entry by Tenant onto the
         Premises, this Lease shall be deemed to apply with respect to the
         requirements that Tenant carry the insurance policies required under
         this Lease, and that Tenant shall indemnify, defend and hold harmless
         Landlord in accordance with the provisions of this Lease, as provided
         in Sections 10 and 11 hereof.

              (b)  TERM.

              TO HAVE AND TO HOLD the same for an initial term of one hundred
         and eighty (180) months commencing upon the date (i) the Premises are
         delivered by Landlord to Tenant as substantially complete in accordance
         with the Plans, and (ii) a temporary certificate of occupancy has been
         issued for the Premises by the Town of Morrisville, NC (the
         "Commencement Date"), and ending 180 months thereafter, unless sooner
         terminated pursuant to the provisions hereof (the "Termination Date").
         The Commencement Date and Termination Date may be extended by Landlord,
         in its discretion, due to delays beyond the control of Landlord,
         including, but not limited to, acts or omissions of Tenant,


                                       3
<PAGE>

         force majeure, delays in obtaining permits, licenses or other
         approvals, acts of God, delays caused by Tenant, and/or inclement
         weather, including site conditions or winter weather that prohibit or
         adversely affect construction (collectively, the "Excused Delays"). In
         the event the Commencement Date has not occurred by December 1, 1999
         due to acts or omissions of Landlord (with such date being extended for
         any Excused Delays), Landlord shall credit against the first
         installment(s) of base rent due hereunder from Tenant an amount equal
         to one day's base rent for each day the Commencement Date is delayed.
         In the event the Commencement Date has not occurred by December 1, 1999
         due to acts or omissions of Tenant (with such date being extended for
         any delay due to acts or omissions of Landlord and any Excused Delay
         except for a Tenant Delay), Landlord shall receive from Tenant on the
         Commencement Date an amount equal to one day's base rent for each day
         the Commencement Date is delayed due solely by reason of a Tenant Delay
         (as hereinafter defined). The aforesaid monetary amounts shall act as a
         sole and exclusive remedy to each party hereto for any delay in the
         Commencement Date. Landlord shall use reasonable efforts to provide
         Tenant at least sixty days prior written notice of the Commencement
         Date. A Tenant Delay shall be defined as a delay due in whole or in
         part to (i) failure by Tenant to furnish information requested by
         Landlord within five business days of the request therefor, or if such
         request may not be satisfied by Tenant within five business days due to
         the time reasonably needed to satisfy such request if Tenant is acting
         in good faith and proceeding diligently, Tenant fails to commence its
         efforts to satisfy such request within five business days or fails to
         diligently pursue satisfaction of a request thereafter; (ii) the acts
         or omissions by a person or entity employed by Tenant in the completion
         of any work in connection with the upfit of the Premises by said person
         or entity; or (c) other acts or omissions, whether negligent, willful,
         or intentional of Tenant, its agents, employees, officers, directors,
         or independent contractors, and as a result of the foregoing, Landlord
         is unable to complete its obligations under this Lease by the
         Commencement Date. Landlord shall provide written notice to Tenant of
         any Tenant Delay as soon as practicable after the occurrence of any
         Tenant Delay.

              (c) Option to Renew. Tenant shall have the option to renew the
         term of the Lease for one renewal period (the "Renewal Term") of five
         lease years in duration, provided that Tenant shall not be in default
         under the Lease on the date such rights are exercised, or on the date
         the Renewal Term shall commence. The date of the commencement of the
         Renewal Term shall be the day after the expiration of the then current
         term of the Lease (unless sooner terminated as provided herein).

         All terms and conditions of this Lease shall be in effect during the
         Renewal Term (including the right of Landlord to increase base rent as
         provided in paragraph 2 of the Lease), except that (i) the base rent
         paid by Tenant during the Renewal Term shall be the lesser of: (1)
         ninety-five percent of the then prevailing market rental rate (the
         "Market Rent") for laboratory buildings in the Research Triangle Park,
         North Carolina area of similar research usage, utility, size, age,
         construction, finishes, upfit, and with similar amenities and
         landscaping, and similar occupancy levels to the Building, as
         reasonably determined by Landlord and Tenant, or (2) $24.00 per
         rentable square foot, triple net; and (ii) upon the exercise by Tenant
         of its right for the Renewal Term, all rights of Tenant to


                                       4
<PAGE>

         renew or extend this Lease term shall lapse. The base rent established
         by Landlord and Tenant for the Renewal Term shall increase on January 1
         of each year during the Renewal Term by two and three-fourths percent
         (2 and 3/4ths) over the base rent paid the previous year. In the event
         that Landlord and Tenant cannot agree upon the base rent to be paid by
         Tenant during the Renewal Term, this Lease shall terminate and the
         options to renew provided to Tenant hereunder shall be null and void
         and of no further force and effect. Tenant shall deliver Landlord
         written notice of its election to exercise its option to renew no less
         than nine (9) months prior to the expiration of the initial term of the
         Lease; failing which Tenant's right to renew for the Renewal Term shall
         be null and void.

              (d) Option to Purchase. Provided there is (i) no default or event
         of default by Tenant under this Lease on the date its rights are
         exercised or upon the date that Tenant shall purchase the Building and
         Land and (ii) Tenant shall continue to lease the entirety of the
         Building, Tenant shall have a one-time right to purchase the Building
         and Land for a purchase price of $15,000,000.00 in cash provided that
         Tenant shall provide Landlord written notice of its intent to exercise
         its Option to Purchase at least nine months prior to the Termination
         Date, and shall close on the purchase on the first business day
         following the Termination Date of the initial term of this Lease.
         Should Tenant fail to comply strictly with the foregoing conditions
         precedent, the rights of Tenant under this Option to Purchase shall be
         null and void and of no further force and effect. Each party hereto
         shall pay its fees and expenses in connection with a closing by Tenant
         upon the Building and Land.

              2.      BASE RENT, OPERATING EXPENSES, AND SECURITY DEPOSIT.

              (a)     BASE RENT.

         calendar month at the end, or the beginning of the term of the Lease,
         shall be prorated. Base rent for the Premises as provided herein has
         been calculated based upon the construction of the Premises as provided
         in the Plans attached hereto. Base rent shall be revised in accordance
         with paragraph 1(a) of this Lease should the Plans be modified and any

              (b) TAXES.

              Beginning on the Commencement Date and continuing for the entire
         term hereof, Tenant shall pay to Landlord, as additional rental,
         Tenant's pro rata share of all taxes, assessments and governmental
         charges of any kind or nature whatsoever levied or assessed against the
         Land and the Building by any municipality, county, or other
         governmental agency (the "Taxes"), which shall be based upon the ratio
         of the square footage of the Premises to the total square footage of
         the Building. Tenant shall pay its pro rata share of the Taxes in
         advance in equal monthly installments in such amounts as are estimated
         for each year by Landlord at the beginning of each calendar year during
         the term, each such installment being made along with payments of base
         rent hereunder. Tenant's share of Taxes for the initial year of the
         term is estimated by Landlord to be $.84 per square foot per year, or
         $4,296.60 per month.

              (c) INSURANCE EXPENSE.

              Beginning on the Commencement Date and continuing for the entire
         term hereof, Tenant shall pay to Landlord, as additional rental,
         Tenant's pro rata share of the insurance premiums (the "Insurance
         Expense") for commercial general liability, and fire and extended
         coverage insurance on the Building and the Land, which shall be based
         upon the ratio of the square footage of the Premises to the total
         square footage of rentable space in the Building. Tenant shall pay its
         pro rata share of the Insurance Expense in advance in equal monthly
         installments in such amounts as are estimated by Landlord at the
         beginning of each calendar year during the term, each such installment
         being made along with payments of base rent hereunder. Tenant's pro
         rata share of the Insurance Expense for the initial year of the term is
         estimated by Landlord to be $.03 per square foot per year or $ 15.35
         per month.

              (d) CAM EXPENSE.

              Beginning on the Commencement Date and continuing for the entire
         term hereof, Tenant shall pay to Landlord, as additional rental,
         Tenant's pro rata share of the cost to Landlord of all the costs and
         expenses of the operation, repair and maintenance of the Premises, the
         Building, its exterior and common areas, and driveways and parking
         areas, including, but not limited to, the costs of lawn maintenance,
         driveway and parking area maintenance for the Premises and for the
         streets and roadways providing access to the Building and the Land,
         management and supervisory fees, costs for the monitoring, review, and
         supervision of Tenant with respect to its maintenance and repair
         responsibilities as set forth in paragraph 4 hereof, exterior lighting
         maintenance, snow removal, repair and maintenance of paved areas,
         cleaning supplies, miscellaneous building supplies, sweeper brushes,

         located, fuel for vehicles and street sweepers used by Landlord in the

         which the Premises are located and miscellaneous maintenance expenses,
         labor, materials, supplies, equipment and tools, permits, licenses,
         inspection fees, window glass replacement and repair, compensation
         (including employment taxes and fringe benefits) of all persons who

         in the Building. Tenant's pro rata share of the CAM Expense for the
         initial year of the term is estimated by Landlord to be $.76 per square
         foot per year or $3,887.40 per month.

              (e)  RECONCILIATION OF EXPENSES.

              Landlord shall promptly notify Tenant of the total actual (i)
         Taxes assessed against the Land and the Building, (ii) Insurance
         Expense, and (iii) CAM Expense, attaching a copy of the tax or special
         assessment bill, the insurance invoice, or the calculation of CAM
         Expense, as applicable, and shall specify (i) Tenant's pro rata share
         thereof, and (ii) the excess, if any, of Tenant's pro rata share over
         Landlord's estimation for such calendar year. Tenant shall pay the
         excess amount so specified to Landlord within thirty (30) days
         following receipt by Tenant of Landlord's letter. Failure by Tenant to
         pay Landlord such amount within the period designated shall constitute
         a non-payment of rent by Tenant and a default of Tenant's obligation
         under the Lease, and Landlord shall be entitled to all remedies
         provided for in this Lease upon default in payment of rent. If the
         first year for which Tenant's pro rata share of Taxes, Insurance
         Expense, or CAM Expense (hereinafter collectively, the "Expenses") are
         due or the final year of the term hereof do not coincide with the
         calendar year, Tenant's pro rata share of Expenses for the portion of
         that year shall be prorated according to the number of months during
         which Tenant was in possession of the Premises. In the event Landlord's
         estimation of Expenses shall exceed the actual amount of Expenses, the
         amount paid by Tenant for such year shall be adjusted between Landlord
         and Tenant and Tenant shall receive a credit against the next due
         installment of rent hereunder in such excess amount unless this Lease
         has expired or been otherwise terminated, in which event Landlord shall
         pay to Tenant such excess amount within thirty (30) days following
         receipt by Tenant of Landlord's letter.

         In the event Tenant shall dispute the amount set forth in any statement
         provided by Landlord under this subparagraph (e), Tenant shall have the
         right, not later than thirty days following the receipt of such
         statement and upon condition that Tenant shall first deposit with
         Landlord the undisputed portion, if any, to elect to have Landlord's
         books and records with respect to such calendar year to be audited by
         auditors selected by Tenant and subject to Landlord's reasonable
         approval. Such audit must be completed no later than 60 days after
         receipt of Landlord's letter, with such time limit to be extended due
         to delays caused by Landlord. All costs for the audit shall be borne by
         Tenant unless the audit disclosed an overcharge of ten percent or more,
         in which case the costs of the audit not to exceed $1,000 shall be
         borne by Landlord. If Tenant shall not request an audit in accordance
         with the provisions of this paragraph within thirty days of receipt of
         Landlord's statement provided pursuant to this subparagraph (e), such
         statement shall be final and binding for all purposes hereof.

              (f) SECURITY FOR PERFORMANCE BY TENANT. Until the day that is the
         sixth anniversary of the Commencement Date, Tenant shall provide
         Landlord with a clean, irrevocable and unconditional letter of credit
         from an issuer satisfactory to Landlord payable to Landlord as
         beneficiary in the amount of $3,000,000.00 (the "Letter of Credit").
         The Letter of Credit must continue at all times in full force and
         effect, shall secure the performance by Tenant under this Lease and may
         be presented by Landlord for payment upon either: (i) the occurrence of
         an event of default under this Lease; or (ii) failure by Tenant to
         provide evidence to Landlord of its renewal of the Letter of Credit at
         least thirty days prior to the then current expiration date of the
         Letter of Credit. Upon the


                                       9
<PAGE>

         end of the fifth lease year hereunder, if the shareholder equity in
         Tenant is not in excess of $90,000,000.00, the Letter of Credit must
         continue to be provided by Tenant for an additional five years upon the
         terms and conditions provided herein. Should Tenant fail to provide
         sufficient evidence to Landlord of its shareholder equity or the
         continued existence of the Letter of Credit prior to the end of the
         fifty-ninth month of the Lease term, Landlord may draw the full
         $3,000,000.00 of the Letter of Credit. Should Landlord draw upon the
         Letter of Credit, Landlord shall reduce the base rent due and payable
         hereunder by Tenant proportionately over the term of the Lease, as
         reasonably determined by Tenant. Should the Lease be terminated for any
         reason, Tenant shall not be entitled to a refund of the amount drawn by
         Landlord under the Letter of Credit. Landlord shall reimburse Tenant
         for its legal fees and expenses in procuring and maintaining the Letter
         of Credit in an amount of up to $30,000.00 each year within thirty days
         after Tenant provides to Landlord reasonable evidence of its fees and
         expenses.

              (g) PROVISIONS TO SURVIVE LEASE TERMINATION.

              Any unperformed obligations of Tenant under this Section 2 shall
         survive the termination of the Lease, for whatever reason, or any
         extension or renewal hereof.

         3.   COMPLIANCE WITH LAWS AND USE.

              (a) The Premises shall be used only for the following purposes:
         the conduct of laboratory testing and research procedures and general
         office purposes related thereto. Tenant shall conduct no activity that
         will result in the discharge of harmful gases, effluents or other
         wastes or toxic substances other than as required in the ordinary
         course of the business of Tenant and in compliance with all applicable
         laws, statutes, and regulations. Outside storage, including, without
         limitation, trucks and other vehicles, is prohibited without Landlord's
         prior written consent except such outside storage as is reflected on
         the Plans. Tenant shall at its sole cost and expense obtain any and all
         licenses and permits necessary for its use of the Premises. Tenant
         shall comply with all governmental laws, ordinances, policies and
         regulations relating to the use of the Premises, and shall promptly
         comply with all governmental orders and directives for the correction,
         prevention and abatement of any violation of such laws, ordinances,
         policies and regulations in or upon, or connected with, the Premises,
         all at Tenant's sole expense. Tenant shall not permit any objectionable
         or unpleasant odors, smoke, dust, gas, noise or vibrations to permeate
         in or emanate from the Premises, nor take any other action which would
         constitute a nuisance or would disturb or endanger any other tenants of
         the Building or unreasonably interfere with their respective premises.
         Tenant shall not receive, store or otherwise handle any product,
         material or merchandise which is explosive, flammable, combustible,
         corrosive, caustic, radioactive, toxic, hazardous or poisonous except
         as required in the ordinary course of the business of Tenant and in
         compliance with all applicable laws, statutes, and regulations. Tenant
         will not permit the Premises to be used for any purpose or in any
         manner (including, without limitation, any method of storage) which
         would render the insurance thereon void or the insurance risk more
         hazardous or cause the State Board of Insurance or other insurance
         authority to disallow any sprinkler credits. Tenant shall give notice
         to Landlord immediately upon the occurrence of any accident or incident
         on the Premises that would trigger reporting requirements under
         applicable laws, including, under the Occupational Safety and Health
         Act, as amended ("OSHA"), or upon Tenant's discovery of any defects
         thereon or in any fixtures or equipment located therein or upon the
         occurrence of any emergency in the Premises or the Building. Tenant
         shall ensure the proper and lawful storage and disposal of all medical,
         radioactive, hazardous, toxic and other substances from the Premises,
         and shall indemnify, defend and hold harmless Landlord, its agents,
         employees, and officers of and from all liability, loss, cost and
         expense incurred due to the improper or unlawful storage and disposal
         by Tenant of any medical, radioactive, hazardous, toxic or other
         substances used by Tenant at the Premises.

              (b) Any costs or expenses for alterations, additions or
         improvements required to modify the common areas of the Building to
         comply with the Americans with Disabilities Act, as amended (the "ADA")
         shall be paid by Landlord throughout the term of this


                                       11
<PAGE>

         Lease. Such alterations, additions or improvements shall be made or not
         made in the sole discretion of Landlord, and Landlord shall be solely
         liable for failure to make the required alterations, additions or
         improvements. All alterations, additions or improvements to the
         Premises required by the ADA on the Commencement Date of this Lease,
         and after the Commencement Date if the initial construction to be
         performed by Landlord has not been completed prior to the Commencement
         Date, shall be made and paid for by Landlord, and Landlord shall be
         solely liable for failure to make such required alterations, additions
         or improvements. Except as provided above, any alterations, additions
         or improvements to the Premises required by any modification or
         supplement to the ADA promulgated after the Commencement Date, shall be
         made and paid for by Tenant, and Tenant shall be solely liable for
         failure to make such required alterations, additions or improvements.
         In the event either party hereto shall fail to make any required
         alterations, additions or improvements pursuant to the ADA, after
         thirty (30) days written notice to the other party hereto, accompanied
         by evidence in support of its position regarding the needed
         alterations, shall have the right but not the obligation to make such
         alterations, additions or improvements at the expense of the other
         party and demand reimbursement of its expenses.

         For purposes of this Lease, the common areas for the Building shall
         consist of the entranceways and private roadways to the Building,
         landscape areas on the Land, and the driveways and parking areas
         located on the Land (hereinafter collectively, the "Common Areas") but
         no third party shall have rights thereto unless specifically granted.
         These common areas may be expanded by Landlord for the benefit of all
         occupants of the Building.

         (c) To the best of Landlord's knowledge, the Premises shall, as of the
         Commencement Date, comply with the ADA.

              4.      REPAIRS AND MAINTENANCE.

              (a) Landlord shall maintain, repair and replace only the roof,
         downspouts, gutters, foundation, utility lines located outside the

         excepted. Tenant shall repair, replace and pay for, any damage to the
         foregoing caused by the negligence of Tenant or Tenant's employees,
         agents or invitees, or caused by Tenant's default hereunder. The term
         "walls" as used herein shall not include interior windows, glass or
         plate glass, doors, special interior store fronts or office entries.
         Tenant shall immediately give Landlord written notice of defect or need
         for repairs, after which Landlord shall have reasonable opportunity to
         repair same or cure such defect. Landlord's liability with respect to
         any defects, repairs or maintenance for which Landlord is responsible
         under any of the provisions of this Lease shall be limited to the cost
         of such repairs or maintenance or the curing of such defect.

              (b) Tenant shall at its own cost and expense maintain, repair and
         replace all parts of the Premises (except those for which Landlord is
         expressly responsible under the terms


                                       12

         laboratory buildings in the Research Triangle Park, North Carolina area
         of similar research usage, utility, size, age, construction, finishes,

         shall not be obligated to repair any damage covered by the insurance to
         be maintained by Landlord pursuant to subparagraph 10(a) below, unless
         due to the acts or omissions of Tenant, its agents, employees, or
         independent contractors.

              (c) If either party hereto shall fail to fulfill its obligations
         under this paragraph, the other party hereto may enter upon the area of
         the Building or the Premises as required to conduct the obligations of
         the defaulting party, and shall be entitled to reimbursement from the
         defaulting party for its actual costs and expenses in conducting such
         obligations. The defaulting party shall reimburse the other party
         hereto for its actual costs and expense promptly upon demand made by
         the other party hereto. The provisions of this subparagraph shall not
         be interpreted to obligate either party hereto to conduct obligations
         of the other party hereto.

              (d) Tenant shall conduct periodic maintenance of all hot water,
         heating and air conditioning systems and units in the Premises, remove

         extermination, and for daily janitorial service and removal of trash
         and debris from the Premises and deposit of trash in exterior

         shall bear sole responsibility for the removal of hazardous, or toxic
         substances, or medical wastes from the Premises and to the appropriate
         site as required under applicable laws, statutes, and ordinances. A
         copy of all of the aforesaid contracts entered into by Tenant shall be
         provided to Landlord on or prior to the Commencement Date.

              (e) Tenant shall not damage any demising wall of the Building, or
         disturb the integrity and support provided by any demising wall and
         shall, at its sole cost and expense, promptly repair any damage or

         or invitees.

              (f) Tenant and its employees, customers and licensees shall have
         the non- exclusive right to use the parking areas on the Land as may be
         designated by Landlord in writing, subject to reasonable rules and
         regulations as Landlord may from time to time prescribe and subject to
         rights of ingress and egress of other tenants. Tenant shall not park on
         streets, rights of ways, driveways, or roadways adjacent to the
         Building or the


                                       13
<PAGE>

         Land, nor allow its employees, agents, invitees, or licensees to do so.
         No vehicles other than passenger vehicles shall be parking on the Land,
         without the prior written consent of the Landlord. Any vehicles,
         including, tractors, trailers, or tractor trailers parked at the
         Building in violation of any provision of this Lease, or abandoned on
         the Land, as reasonably determined by Landlord, are subject to removal
         by Landlord, at the cost and expense of Tenant, and Tenant shall
         indemnify, defend, and hold harmless Landlord of and from all loss,
         cost and expense incurred by Landlord in the enforcement of the

         needs of other tenants of the Building, and shall not violate the
         rights of other tenants of the Building. So long as Tenant shall
         continue to lease at least 61,380 rentable square feet, Tenant shall
         have the non-exclusive use of 172 parking spaces at the Building (this
         total includes handicapped parking spaces; provided, however, in the
         event any improvements, or equipment located by Tenant on the Land
         consume any portion of the parking area located on the Land, the
         parking spaces affected shall be counted against the parking ratio
         available for use by Tenant at the Premises. Landlord shall act
         reasonably to enforce Tenant's parking rights against any third
         parties. Landlord may require, at its option, in its sole discretion,
         that Tenant, its employees, invitees, and visitors use certain numbered
         spaces to be designated by Landlord.

              5.      ALTERATIONS.

              (a) Subject to the provisions of this subparagraph (a), Tenant
         shall not make any alterations, additions or improvements to the
         Premises (including, but not limited to, roof and wall penetrations)
         without the prior written consent of Landlord, which consent shall not
         be unreasonably withheld; provided, however, should Tenant submit
         preliminary plans for making an alteration to the Premises and such
         plans are in form sufficient for Landlord to review the alteration
         contemplated by Tenant, Landlord shall respond within ten business days
         of its receipt of such plans, or the plans and the alteration to be
         made by Tenant shall be deemed approved. If the plans submitted by
         Tenant are insufficient for Landlord to review the contemplated
         alteration, Landlord shall so notify Tenant and Tenant shall revise and
         resubmit the plans to Landlord but the ten day time period for Landlord
         to act as aforesaid shall not be deemed to commence until such time as
         Tenant shall have submitted a sufficient plan to Landlord, as
         reasonably determined by Landlord. All submissions of plans to Landlord
         under this paragraph 5 shall be sent in accordance with the provisions
         of paragraph 20 hereof. Landlord may require as a condition to Tenant
         making any alteration to the Premises that Tenant restore the Premises
         to its condition as of the Commencement Date prior to Tenant vacating
         the Premises. 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 trade fixtures and remove and replace
         interior non-structural walls, as it may deem advisable, without
         altering the basic character or structure of the Premises or
         improvements and without overloading or damaging the Premises or
         improvements, and in each case complying with all applicable
         governmental laws, ordinances, regulations and other requirements.
         Tenant shall not make any alterations, additions or improvements to the
         Premises which will contravene Landlord's policies insuring against
         loss or damage by fire or other hazards, including but not limited to
         commercial general liability, or which will prevent Landlord from
         securing


                                       14
<PAGE>

         such policies in companies acceptable to Landlord. If any such
         alterations, additions or improvements cause the rate of fire or other
         insurance on the Premises by companies acceptable to Landlord to be
         increased beyond the minimum rate from time to time applicable to the
         Premises for permitted uses thereof, Tenant shall pay as additional
         rent the amount of any such increase promptly upon demand by Landlord.

              (b) Any and all alterations, additions, improvements, partitions
         and fixtures erected by Tenant shall be the property of Landlord and
         shall remain at the Premises upon termination of the Lease or upon
         earlier vacating of the Premises. All shelves, bins, machinery, trade
         fixtures and other specialized equipment installed and paid for by
         Tenant may be removed by Tenant prior to the termination of this Lease
         provided such removal may be accomplished without damage to the
         Premises or to the primary structure or structural qualities of the
         Building and other improvements situated on the Premises. Tenant shall
         repair any damage to the Premises, or to the Building as a result of
         any alteration, addition, improvement, or repair to the Premises, or
         the removal of personal property or trade fixtures by Tenant, its
         employees, agents, invitees, or contractors to the Premises. Should
         Tenant fail to conduct any such repair within ten days of written
         notice from Landlord, Landlord may, at its option, perform same, and
         Tenant shall remit payment to Landlord for the actual cost and expense
         incurred by Landlord in effecting such repair immediately upon demand.

              6.      SIGNS.

              (a) Landlord shall install at its expense a monument sign on the
         Land containing the name of Tenant. In addition, Landlord shall include
         the name of Tenant on the Building directory. All signs for the
         Premises shall be in form and substance, location, color, shape, size
         (including, height, width and length of lettering and total signage)
         and configuration, mutually and reasonably approved by Landlord.

              (b) Tenant shall have the right to install signs upon the Premises
         only when first approved in writing by Landlord and subject to any
         applicable governmental laws, ordinances, regulations and other
         requirements. Tenant shall remove all such signs upon the termination
         of this Lease. Such installations and removals shall be made in such
         manner as to avoid injury or defacement of the Premises, and Tenant
         shall repair any injury or defacement, including, without limitation,
         discoloration of the Building caused by such installation and/or
         removal. Tenant shall have the right to install paraphet signage on the
         Building at the expense of Landlord, and provided Tenant complies with
         the provisions of this paragraph 6.

              7.      INSPECTION AND ENTRY.

              (a) 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 purpose of ascertaining the condition of the Premises or
in order to make such repairs as may be required or permitted to be made by
Landlord under the terms of this Lease or in order to show the Premises to any
prospective purchaser or lender so long as Landlord shall be escorted by an
employee of


                                       15
<PAGE>

Tenant, or the agent or employee of Landlord entering the Premises shall have
received training from Tenant with respect to entry upon the Premises based upon
the usage of the Premises by Tenant. During the period that is six (6) months
prior to the end of the term hereof, 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 to any
prospective tenant and shall have the right to erect on the Premises a suitable
sign indicating the Premises are available. Tenant shall schedule with Landlord
at least sixty (60) days prior to vacating the Premises a time mutually
agreeable to the parties hereto for a joint inspection of the Premises prior to
vacating. In the event of Tenant's failure to give 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
responsibilities for repairs and restoration.

              (b) Within thirty days of the Commencement Date of this Lease,
Tenant shall develop and provide a copy to Landlord of its hazard communication
plan (the "Plan") with respect to any accidents or incidents at the Building,
and shall thereafter provide Landlord with any amendments to the Plan within
five days of their development. Tenant shall ensure that the Plan complies with
all applicable laws, statutes, and regulations. Tenant shall bear all costs of
training the employees of Landlord with respect to the Plan, and any amendments
thereof.

              (c) Tenant shall provide Landlord immediately a copy of any
notices or correspondence it receives from OSHA, or from any other state,
federal, or local agency concerning the Premises.

              (d) Tenant shall provide to Landlord training for its employees
and staff that may enter the Building. This training shall be provided on an
annual basis and shall be sufficient to apprise the employees and staff of
Landlord of the usage of Tenant of the Building and the safety concerns with
respect to any entry thereon. Training updates shall be provided by Tenant to
Landlord upon the same schedule as provided to employees of Tenant. All training
shall be provided in the Building or in another building of Landlord located
nearby and shall be at the cost and expense of Tenant.

              8. UTILITIES. Landlord agrees to provide at its cost, all utility
line connections into the Premises. Tenant shall contract and pay for all
utilities for the Premises directly with each service provider of the Premises.
Landlord shall not be liable for any interruption or failure of utility services
on the Premises; provided, however, in the event any utility service to the
Premises is interrupted due to acts or omissions of Landlord, the liability of
Landlord therefor shall be the costs to restore same.

              9. ASSIGNMENT AND SUBLETTING. Tenant shall not sublet the Premises
or the interest of Tenant therein in whole or in part, or assign this Lease or
the interest of Tenant therein in whole or in part, without the prior written
consent of Landlord, which consent shall not be unreasonably withheld or
delayed. Further, Tenant may not sell, lien, or encumber its interest in this
Lease, or assign or delegate the management or permit the use or occupancy of
the Premises in whole or in part by anyone other than Tenant without the prior
written consent of Landlord, which consent Landlord may withhold in its sole
discretion. Landlord and Tenant acknowledge and agree that the foregoing
provisions have been freely negotiated by the parties


                                       16
<PAGE>

hereto and that Landlord would not have entered into this Lease without Tenant's
consent to the terms of this Paragraph 9.

              In no event shall this Lease be assignable by operation of any
law, without the prior written consent of Landlord which consent shall not be
unreasonably withheld, and Tenant's rights hereunder may not become, and shall
not be listed by Tenant as an asset under any bankruptcy, insolvency, or
reorganization proceedings. No assignment, transfer, mortgage, sublease or other
encumbrance, whether or not approved, and no indulgence granted by Landlord to
any assignee or subtenant, shall in any way impair the continuing primary
liability (which after an assignment shall be joint and several with the
assignee) of Tenant hereunder, and no approval in a particular instance shall be
deemed to be a waiver of the obligation to obtain Landlord's approval in any
other case.

              If for any approved assignment or sublease Tenant receives rent or
other consideration, either initially or over the term of the assignment or
sublease, in excess of the base rent hereunder, or in case of a sublease of part
of the Premises, in excess of the portion of such rent fairly allocable to such
part, after appropriate adjustments to assure that all other payments called for
hereunder are appropriately taken into account, Tenant shall pay to Landlord as
additional rent one-half of the full excess of each such payment of rent or
other consideration received by Tenant promptly after its receipt.
Notwithstanding the foregoing, if Tenant shall offer any sublease or assignment
of space in the Premises for less than the current asking price of Landlord for
space comparable in size and usage by Landlord to a prospective tenant in an
arms length transaction at the current fair market value for such space (which
asking price Landlord shall provide to Tenant upon request made therefor), then
Landlord shall be entitled to receive all of the full excess of each such
payment of rent or other consideration received by Tenant promptly after its
receipt.

              Notwithstanding any provision of this Lease to the contrary,
should Tenant receive consent from Landlord to sublease or assign its interest
in the Premises and seek to sublease or assign its interest in the Premises in
accordance with this paragraph, Tenant shall not use the name of Landlord, any
insignia of Landlord, or any likeness of the Building in any of its advertising
for such sublease or assignment.

              10.     FIRE AND CASUALTY DAMAGE.

              (a) Landlord agrees to maintain standard fire and extended
         coverage insurance for the Building in an amount not less than full
         replacement cost as such term is defined in the Replacement Cost
         Endorsement to be attached thereto, insuring against special causes of
         loss, including, the perils of fire, and lightning, 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 of North Carolina. Subject to the provisions of subparagraphs
         10(c), 10(d) and 10(e) below, such insurance shall be for the sole
         benefit of Landlord and under its sole control.

                                       17
<PAGE>

              (b) If the Premises should be damaged or destroyed by any peril
         covered by the insurance to be provided by Landlord under subparagraph
         10(a) above, Tenant shall give immediate written notice thereof to
         Landlord.

              (c) If the Premises should be totally destroyed by any peril
         covered by the insurance to be provided by Landlord under subparagraph
         10(a) above, or if they should be so damaged thereby that rebuilding or
         repairs cannot in Landlord's estimation be completed within one hundred
         and eighty (180) days after the date upon which Landlord is notified by
         Tenant of such damage, this Lease shall terminate and the rent shall be
         abated during the unexpired portion of this Lease, effective upon the
         date of the occurrence of such damage.

              (d) If the Premises should be damaged by any peril covered by the
         insurance to be provided by Landlord under subparagraph 10(a) above,
         but only to such extent that rebuilding or repairs can, in Landlord's
         estimation, be completed within one hundred and eighty (180) days after
         the date upon which Landlord is notified by Tenant of such damage, this
         Lease shall not terminate, and Landlord shall, at its sole cost and
         expense, thereupon proceed with reasonable diligence to rebuild and
         repair the Premises to substantially the condition in which they
         existed prior to such damage, except that 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 they are untenantable
         shall be abated as may be fair and reasonable under all of the
         circumstances, as reasonably determined by Landlord and Tenant.

              (e) 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 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 thereafter accruing
         shall cease and terminate.

             (f) Each of Landlord and Tenant hereby waives all rights to recover
         against each other or against any other tenant or occupant of the
         Building, or against the officers, directors, shareholders, partners,
         joint venturers, employees, agents, customers, invitees, or business
         visitors of each other or of any other tenant or occupant of the
         Building, for any loss or damage arising from any cause covered by any
         insurance required to be carried by each of them pursuant to this
         Lease, or any other insurance actually carried by either of them.
         Landlord and Tenant shall cause their respective insurers to issue
         waiver of subrogation rights endorsements to all policies of insurance
         carried in connection with the Building or the Premises or the contents
         of either of them, and any cost for the issuance of such endorsements
         shall be borne by the original insured under such policies.

              (g) The obligation of Landlord in this paragraph 10 to repair and
         restore the Premises and the Building as provided herein, does not
         include an obligation of Landlord to repair


                                       18
<PAGE>

         the fixtures, equipment, or personal property of Tenant, which Tenant
         shall insure for its benefit, and Tenant shall have the obligation to
         repair and restore in the event of a casualty or other loss to the
         extent that replacement of such items is appropriate for the Tenant's
         continuing use of the Premises.

              (h) The period of time within which repair and restoration of the
         Premises must be completed shall be extended due to delays occasioned
         by force majeure; provided, however, all repair and restoration must be
         completed by Landlord within 360 days after the date of the casualty.

              11. LIABILITY. Landlord shall not be liable to Tenant or Tenant's
employees, agents, officers, partners, licensees or invitees, or to any other
person whomsoever, for any damage to property on or about the Premises belonging
to Tenant or any other person, due to any cause whatsoever, unless caused by the
gross negligence, or willful or intentional misconduct of Landlord.

              Tenant hereby covenants and agrees that it will at all times
indemnify, defend (with counsel approved by Landlord) and hold safe and harmless
Landlord (including, without limitation, its trustees and beneficiaries if
Landlord is a trust), and Landlord's agents, employees, patrons and visitors
from any loss, liability, claims, suits, costs, expenses, including without
limitation attorney's fees and damages, both real and alleged, incurred by
Landlord, its agents, employees, officers, partners, invitees, or licensees
arising out of or resulting from the occupancy by Tenant of the Premises, a
breach by Tenant of any provision of this Lease, or the conduct by Tenant of its
business in the Building.

              Landlord hereby covenants and agrees that it will at all times
indemnify, defend (with counsel reasonably approved by Tenant) and hold safe and
harmless Tenant (including, without limitation, its trustees and beneficiaries
if Tenant is a trust), and Tenant's agents, employees, patrons and visitors from
any loss, liability, claims, suits, costs, expenses, including without
limitation attorney's fees and damages, both real and alleged, incurred by
Tenant, its agents, employees, officers, partners, invitees, or licensees
arising out of or resulting from a breach by Landlord of any provision of this
Lease.

              Tenant shall procure and maintain throughout the term of this
Lease a policy or policies of insurance, at its sole cost and expense, naming
Landlord as an additional insured, and insuring both Landlord 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; (iv) the equipment, personal property and
fixtures of Tenant located on the Premises; (v) any interruption in the conduct
of the business of Tenant on the Premises; (v) Tenant's liability assumed under
this Lease, and such other kinds of insurance as Landlord shall reasonably
request. The limits of coverage maintained by Tenant for (i) commercial general
liability shall be not less than $5,000,000.00 with respect to each occurrence,
not less than $5,000,000.00 with respect to personal injury or death of a single
person, not less than $5,000,000 general aggregate, and not less than
$5,000,000.00 with respect to products completed operations aggregate, (ii) for
business interruption insurance shall be not less than


                                       19
<PAGE>

coverage for actual loss, and (iii) for replacement of the equipment, personal
property and fixtures of Tenant shall be not less than full replacement value.

              All such policies shall be procured by Tenant from responsible
insurance companies satisfactory to Landlord with an A.M. Best's Rating of at
least "A". Certified copies of such policies, together with receipt evidencing
payments of premiums thereof, shall be delivered to Landlord prior to the
Commencement Date. 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 prior written notice shall be given to Landlord before such policy may be
canceled or changed to reduce insurance provided thereby.

              12.     CONDEMNATION.

              (a) If the whole or any substantial portion 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 by Tenant for the purposes
         provided herein, this Lease shall terminate and the rent shall be
         abated during the unexpired portion of this Lease, effective when the
         physical taking of the Premises shall occur.

              (b) If a portion 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 the use by Tenant of the Premises is not materially interfered
         with, this Lease shall not terminate but the rent payable hereunder
         during the unexpired portion of this Lease shall be reduced in an
         amount that shall be reasonable under all of the circumstances.

              (c) In the event of any such taking or private purchase in lieu
         thereof, Landlord shall be entitled to receive and retain all awards as
         may be awarded in any condemnation proceedings other than those
         specifically awarded Tenant for a taking of Tenant's personal property,
         loss of business and moving expenses.

              13.     HOLDING OVER AND TERMINATION.

              (a) Tenant shall upon the termination of this Lease by lapse of
         time or otherwise, yield up immediate possession to Landlord without
         the requirement of notice by Landlord to Tenant of the termination of
         this Lease, nor any grace or cure period should Tenant fail to yield up
         immediate possession to Landlord. Unless the parties hereto shall
         otherwise agree in writing, if Landlord agrees in writing that Tenant
         may hold over after the expiration or termination of this Lease, the
         hold over tenancy shall be subject to termination by Landlord at any
         time upon not less than five (5) days advance written notice, or by
         Tenant at any time upon not less than thirty (30) days advance written
         notice, and all of the other terms and provisions of this Lease shall
         be applicable during that period, except that Tenant shall pay Landlord
         from time to time upon demand, as rental for the period of any hold
         over, an amount equal to one and 35/100 (1-35/100) the


                                       20
<PAGE>

         rent in effect on the termination date, computed on a daily basis for
         each day of the hold over period. No holding over by Tenant, whether
         with or without consent of Landlord, shall operate to extend this Lease
         except as otherwise expressly provided. The preceding provisions of
         this Paragraph 13 shall not be construed as Landlord's consent for
         Tenant to hold over.

              (b) Upon the termination of this Lease for whatever reason, Tenant
         shall quit and immediately surrender the Premises to Landlord, broom
         clean, in good order and condition with all repairs and maintenance
         required by Tenant hereunder having been performed, ordinary wear and
         tear and damage by casualty that is the responsibility of Landlord to
         repair excepted, and Tenant shall remove its personal property from the
         Premises in accordance with this Lease. Should any of the personal
         property or trade fixtures of Tenant remain upon the Premises after the
         Termination Date, all such property shall be deemed abandoned by
         Tenant, and Landlord may remove same at the cost and expense of Tenant
         with no liability to Tenant therefore, and Tenant hereby releases
         Landlord from all liability therefor.

              14. 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, deed of trust(s), or mortgage(s) of record,
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.

              15. 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 any installment of the rent herein
         reserved, or payment with respect to taxes hereunder, or any other
         payment or reimbursement to Landlord required herein, within five (5)
         days of when due; provided, however, the aforesaid five day period
         shall be extended to ten days for any one instance in a twelve month
         period in which Tenant shall make a payment after the five day period.

              (b) Tenant shall become insolvent, or shall make a transfer in
         fraud of creditors, or shall make an assignment for the benefit of
         creditors.

              (c) Tenant shall file a petition under any section or chapter of
         the Bankruptcy Reform Act, as amended or under any similar law or
         statute of the United States or any state thereof; or Tenant shall be
         adjudged bankrupt or insolvent in proceedings filed against Tenant
         thereunder.

                                       21
<PAGE>

              (d) A receiver or trustee shall be appointed for all or
         substantially all of the assets of Tenant.

              (e) Tenant shall desert all of the Premises.

              (f) Tenant shall fail to yield up immediate possession of the
         Premises to Landlord upon termination of this Lease.

              (g) Tenant shall fail to comply with the provisions of this Lease
         concerning the Letter of Credit as required in paragraph 2 hereof.

              (h) Tenant shall fail to comply with any term, provision or
         covenant of this Lease (other than the provisions of subparagraphs (a),
         (b), (c), (d), (e),(f) and (g) of this Paragraph 15), and shall not
         cure such failure within twenty (20) days after written notice thereof
         to Tenant, or such additional period of time as shall be granted by
         Landlord should Landlord determine that Tenant is acting in good faith
         and proceeding diligently to effect a cure but additional time is
         required by Tenant to complete a cure.

              16. REMEDIES. Upon the occurrence of any event of default in
Paragraph 15 hereof, Landlord shall have the option to pursue any remedy at law
or in equity, including, but not limited to, one or more of the following
remedies without any notice or demand whatsoever:

              (a) Terminate this Lease, in which event Tenant shall immediately
         surrender the Premises to Landlord, and if Tenant fails to do so,
         Landlord may, without prejudice to any other remedy which it may have
         for possession or arrearage in rent, enter upon and take possession of
         the Premises and expel and remove Tenant and any other person who may
         be occupying the Premises or any part thereof, with or without judicial
         approval, by any legal means necessary, without being liable for
         prosecution or any claim of damages therefor; secure the Premises
         against unauthorized entry; and Tenant agrees to pay to Landlord on
         demand the amount of all loss and damage which Landlord may suffer by
         reason of such termination, whether through inability to relet the
         Premises on satisfactory terms or otherwise.

              (b) Enter upon and take possession of the Premises and expel or
         remove Tenant and any other person who may be occupying such Premises
         or any part thereof, with or without judicial approval, by any legal
         means necessary, without being liable for prosecution and receive the
         rent thereof; secure the Premises against unauthorized entry; store any
         property located on the Premises at the expense of the owner thereof
         and Tenant agrees to pay to Landlord on demand any deficiency that may
         arise by reason of such reletting. In the event Landlord is successful
         in reletting the Premises at a rental in excess of that agreed to be
         paid by Tenant pursuant to the terms of this Lease, Landlord and Tenant
         each mutually agree that Tenant shall not be entitled, under any
         circumstances, to such excess rental, and Tenant does hereby
         specifically waive any claim to such excess rental.

                                       22
<PAGE>

              (c) Enter upon the Premises, with or without judicial approval, by
         any legal means necessary, without being liable for prosecution or any
         claim for damages therefor, secure the Premises against unauthorized
         entry, remove all property of Tenant from the Premises and store it at
         the cost and expense of Tenant, and do whatever Tenant is obligated to
         do under the terms of this Lease; and Tenant agrees to reimburse
         Landlord on demand for any expenses which Landlord may incur in thus
         effecting compliance with Tenant's obligations under this Lease, and
         Tenant further agrees that Landlord shall not be liable for any damages
         resulting to Tenant from such action, whether caused by the negligence
         of Landlord or otherwise.

              (d) Accelerate and demand the payment of all base rent and other
         charges due and payable hereunder over the term of this Lease which
         amount shall be reduced by any amounts received by Landlord from any
         new tenant that enters into occupancy of the Premises.

              In the event Tenant fails to pay any installment of base rent or
additional rent hereunder within fifteen days of the due date of such
installment, Tenant shall pay to Landlord on demand a late charge in an amount
equal to four percent (4%) of such installment to help defray the additional
cost to Landlord for processing such late payment. 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. 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 and all reasonable
attorneys' fees so incurred.

              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 or equity, 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 the Premises shall be valid unless
in writing signed by Landlord. No 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 after the occurrence of an
event of default shall not be construed as a waiver of such default, unless
Landlord so notifies Tenant in writing, and no receipt of money by Landlord from
Tenant after the termination of this Lease or after service of any notice or
after the commencement of any suit or after final judgment for possession of the
Premises shall reinstate, continue or extend the term of this Lease or affect
any such termination, notice, suit or judgment, 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 waiver of such default or of Landlord's right to enforce
any such remedies with respect to such default or any subsequent default.

              17. LANDLORD'S LIEN.  [INTENTIONALLY DELETED.]

              18. 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 other
documents which may be required by any mortgagee or trustee for the purpose of
further subjecting and subordinating this Lease to the lien of any such mortgage
or deed to trust, and shall forward same to Landlord within five days of a
request therefor; provided, that any current or future mortgagee, trustee, or
deed of trust beneficiary, as the case may be, shall provide Tenant with a
nondisturbance agreement in form reasonably satisfactory to Tenant which shall
grant Tenant the right to continue to occupy the Premises under the terms hereof
so long as Tenant is not in default under this Lease.

              19. MECHANIC'S 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 Landlord in the Premises or under
the terms of this Lease.

              20. NOTICES. Each provision of this instrument or of any
applicable governmental laws, ordinances, regulations, or other requirements
with reference to the sending, mailing, or delivery of any notice by Landlord to
Tenant or with reference to the sending, mailing, or delivery of any notice or

              22. LANDLORD'S LIABILITY. Notwithstanding anything to contrary
contained in this Lease, Tenant agrees and understands that Tenant shall look
solely to the estate and property of Landlord in the Building for the
enforcement of a judgment (or other judicial decree) requiring the payment of

performance of its obligations under this Lease, it being intended that there
will be absolutely no personal liability on the part of Landlord, its successors
and assigns with respect to any of the terms, covenants, and conditions of this
Lease, and no other assets of Landlord or of Landlord's partners, if any, shall
be subject to levy, execution, attachment or any other legal process for the

         thereof as a site for the treatment, storage, or disposal (whether
         permanent or temporary) of any Hazardous Material, other than materials
         used in the ordinary course of the business of Tenant in accordance
         with all Applicable Laws. Tenant further agrees that it will not cause
         or allow any asbestos to be incorporated into any improvements or
         alterations which Tenant makes or causes to be made to the Premises, or
         the Building.

              (b) Tenant hereby agrees to indemnify, defend (with counsel

         includes any radioactive, hazardous or toxic substance, pollutant,
         contaminant, effluent, gas, petroleum product or medical product or
         waste defined as such in (or for purposes of) the Comprehensive
         Environmental Response, Compensation, and Liability Act, as amended,
         any so-called "Superfund" or "Superlien", law, the Toxic Substances
         Control Act, as amended, or any other Federal, state or local statute,

         any radioactive, hazardous, toxic or dangerous waste, substance or
         material, as now or at any time hereafter in effect, or any other
         hazardous, toxic or dangerous, waste, substance or material, gas or
         petroleum product, and "Applicable Laws" shall mean the Comprehensive
         Environmental Response, Compensation, and Liability Act, as amended,
         any so-called "Superfund" or "Superlien", law, the Toxic Substances
         Control Act, as amended, or any other Federal, state or local statute,

         Landlord.

              25. [INTENTIONALLY DELETED.]

              26. COVENANT OF TENANT. If Landlord encounters difficulties in
negotiating permanent or construction financing for the Building, and after
using its best efforts is unable to resolve those difficulties without obtaining
minor modifications to this Lease, Tenant will act in good faith to execute an
amendment to this Lease, but this agreement on the part of Tenant will not
require Tenant to make any changes that in Tenant's reasonable judgment alter
the term hereof, or adversely affect any substantive right of Tenant, whether
legal or economic.

              27.     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. Each party agrees to
         furnish to the other, promptly upon demand, a resolution, or other
         appropriate documentation evidencing the due authorization of such
         party to enter into this Lease.

                                       28

              (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 agrees from time to time, within ten (10) days after
         request of Landlord, to deliver to Landlord, or Landlord's designee, an
         estoppel certificate stating that this Lease is in full force and
         effect, the date to which rent has been paid, the unexpired term of
         this Lease and such other matters pertaining to this Lease as may be
         requested by Landlord. It is understood and agreed that Tenant's
         obligation to furnish such estoppel certificates in a timely fashion is
         a material inducement for Landlord's execution of this Lease.

              (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 concerning the
         condition of the Premises.

              (g) In the event of a transfer by Landlord of its interest in the
         Premises, Landlord shall be released from all obligations and
         liabilities under the terms of this Lease subsequent to the date of
         such transfer. In the event a transferee shall agree to assume the
         obligations and liabilities of Landlord under the Lease prior to the
         date of the transfer, Landlord shall be released from all obligations
         and liabilities under the Lease.

              (h) If any clause or provision of this Lease is illegal, invalid
         or unenforceable under present or future laws effective during the term
         of this Lease, then and in that event, it is the intention of the
         parties hereto that the remainder of this Lease shall not be affected
         thereby, and it is also the intention of the parties to this Lease that
         in lieu of each clause or provision of this Lease that is illegal,
         invalid or unenforceable, there be added as a part of this Lease
         contract a clause or provision as similar in terms to such illegal,
         invalid or unenforceable clause or provision as may be possible and be
         legal, valid and enforceable.

              (i) [INTENTIONALLY DELETED.].

              (j) 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.

              (k) Time is of the essence of this Lease.

              (l) (i) If Landlord (1) breaches any agreement or obligation in
         this Lease and such breach continues for a period of thirty (30) days
         after written notice to Landlord by


                                       29
<PAGE>

         Tenant, or (2) through Landlord's gross negligence or willful act,
         Landlord fails to provide (where Landlord is obligated to provide the
         Landlord Essential Service), or Landlord fails to act reasonably to
         cause a cure (but only to the extent that Landlord is responsible for
         the cure and such cure is within Landlord's control to effect) or
         Landlord otherwise affirmatively acts to stop, interrupt or materially
         reduce a Landlord Essential Service (as hereinafter defined) so that
         Tenant is not able to carry on its business at the Premises for five
         (5) consecutive business days and such interruption continues for a
         period of five (5) business days after written notice to Landlord, then
         upon the occurrence of (l) and/or (2) above, if Landlord shall not in
         good faith have commenced the curing of such breach specified in (1) or
         (2) above within such thirty (30) or five (5) business day period after
         written notice, as the case may be and thereafter, shall have not
         diligently and continuously proceeded to cure such breach completely,
         the Landlord shall be in default hereunder, and Tenant shall have all
         rights and remedies available at law or in equity for such default.

         (ii) In addition, Tenant shall have the right but not the obligation,
         to effect a cure on behalf of Landlord and to demand the actual and
         reasonable costs of cure from Landlord.

         (iii) For purposes of this Lease, a "Landlord Essential Service" does
         not mean a service to be provided by Landlord under this Lease per se,
         but rather a facility or system within the Building controlled,
         operated or maintained by Landlord (but not a third party, e.g.,
         Carolina Power & Light Company, to the extent that such third party is
         responsible) that provides electricity, elevator service,
         telecommunications (including data transmission), and heating, air
         conditioning and ventilation and are necessary for the purpose of
         Tenant's conduct of its business at the Premises. (iv) Landlord shall
         have no liability for any incidental or consequential damages of
         Tenant, or anyone claiming by, through or under Tenant, for any reason
         whatsoever.

              (m) In the event that Landlord shall default in the performance of
         Landlord's obligations hereunder, the holder of a mortgage or the
         beneficiary of a deed of trust which includes the Premises shall have
         the right, but not the obligation, to perform or comply with any
         covenants, agreements and provisions violated in connection with such
         default. Further, if such holder or beneficiary notifies Tenant that
         such holder or beneficiary has taken over Landlord's right under this
         Lease, Tenant shall not assert any right to deduct the cost of repairs
         or any monetary claims against Landlord theretofore accrued from rent
         thereafter due and payable, but shall look solely to Landlord and not
         such holder or beneficiary for satisfaction of such claim.

              (n) This Lease does not create the relationship of partner or
         joint venturer between Landlord and Tenant.

              (o) The laws of the State of North Carolina shall govern the
         interpretation, the validity, performance and enforcement of this
         Lease.

              (p) The undersigned officer of Tenant does hereby warrant and
         certify to Landlord that Tenant is a corporation in good standing and
         duly organized under the laws of the


                                       30
<PAGE>

         State of Texas and is authorized to do business in the State of North
         Carolina. The undersigned officer of Tenant hereby further warrants and
         certifies to Landlord that such officer is authorized and empowered to
         bind the corporation to the terms of this Lease by such officer's
         signature hereto. Tenant shall provide Landlord a consent of its
         officers and directors to enter into this Lease, and the person
         authorized to sign this Lease on behalf of Tenant concurrently with the
         execution of this Lease.

              (q) This Lease shall be executed in duplicate, each of which shall
         be deemed an original and complete of itself and may be introduced into
         evidence or used for any purpose without the production of any other
         copy. If Tenant is a corporation, two authorized corporate officers
         must execute this Lease in their appropriate capacity for Tenant and
         affix the corporate seal.

              (r) The provisions contained in the Rider attached hereto, if any,
         are incorporated herein by reference and made a part of this Lease. In
         the event of any conflict between the printed portion of this Lease and
         the Rider, the provisions of the Rider shall govern and control.

              (s) Although the printed provisions of this Lease were drafted by
         Landlord, such fact shall not cause this Lease to be construed either
         for or against Landlord or Tenant.

              (t) This Lease may not be recorded. Upon the request and at the
         expense of Tenant, Landlord shall execute a memorandum of this Lease
         suitable for recording which shall omit the financial terms herein but
         which shall identify the Premises and the term of this Lease. Upon the
         expiration of this Lease, a recorded memorandum of this Lease may be
         canceled of record by a document executed by Landlord, or its successor
         in interest for such purpose.

              (u) Within five days of the request by Landlord upon the
         occurrence of a default or event of default hereunder by Tenant, Tenant
         shall provide to Landlord, financial statements of Tenant certified by
         the chief financial officer of Tenant.

              (v) No remedy conferred herein is intended to be exclusive of any
         other remedy and each and every remedy shall be cumulative and shall be
         in addition to every other remedy given hereunder or thereunder or now
         or hereafter existing at law or in equity or by statute or otherwise.

              (w) No provision of this Lease shall be deemed to waive any
         statutory (as provided in Chapter 44A of the North Carolina General
         Statutes), or common law rights of Landlord to assert a lien upon
         property of Tenant.

conditions hereof, the Bank agrees to make revolving loans to the Borrower upon
request in an aggregate principal amount of up to EIGHT MILLION DOLLARS
($8,000,000) at any time outstanding. The loans hereunder may consist of Prime

extensions or conversions of loans hereunder), shall be made by written notice

request shall be deemed to be a request for an Interest Period of one month.
Each request for a Loan hereunder shall be deemed a reaffirmation that the

                                       6
<PAGE>

         2.3 Interest Rate. Loans outstanding hereunder shall bear interest at a
per annum rate equal to (i) the LIBOR Rate plus five-eighths of one percent
(.625%) or (ii) the Prime Rate, as the Borrower may elect; provided that after
the occurrence and during the continuance of an Event of Default, the principal
and, to the extent permitted by law, interest on the Loans and any other amounts
owing hereunder shall bear interest, payable on demand, at a rate equal to the
Prime Rate plus two percent (2%). Interest will be payable in arrears on each
Interest Payment Date.

         2.4 Repayment. Unless sooner paid, the Loans shall be due and payable
in full on the Termination Date.

         2.5 Note. The Loans shall be evidenced by a promissory note of the
Borrower dated as of the Closing Date, in the form of Annex A hereto (as
amended, modified, extended, renewed or replaced, the "Note").

         2.6 Fees. In consideration of the commitments hereunder, the Borrower
agrees to pay to the Bank a facility fee (the "Facility Fee") equal to ten basis
points (.10%) per annum on the average daily unused portion of the commitment
for the applicable period. The Facility Fee shall be payable quarterly in
arrears on the 15th day following the last day of each calendar quarter for the
immediately preceding quarter (or portion thereof) beginning with the first such
date to occur after the date hereof.

         2.7 Prepayments. The Loans may be prepaid in whole or in part without
premium or penalty. LIBOR Rate Loans may not be prepaid in whole or in part
prior to the end of the applicable Interest Period. Amounts prepaid may, subject
to the terms and conditions hereof, be reborrowed.

         2.8 Capital Adequacy. If the Bank shall have reasonably determined that
the adoption of or any change in any Requirement of Law regarding capital
adequacy or in the interpretation or application thereof as a consequence of its
obligations hereunder or compliance by the Bank or any corporation controlling
the Bank with any request or directive regarding capital adequacy (whether or
not having the force of law) from any central bank or Governmental Authority
made subsequent to the date hereof as a consequence of its obligations hereunder
does or shall have the effect of reducing the rate of return on the Bank's or
such corporation's capital as a consequence of its obligations hereunder to a
level below that which the Bank or such corporation could have achieved but for
such adoption, change or compliance (taking into consideration the Bank's or
such corporation's policies with respect to capital adequacy) by an amount
reasonably deemed by the Bank to be material, then from time to time, within 15
days after demand by the Bank, the Borrower shall pay to the Bank such
additional amount as shall be certified by the Bank as being required to
compensate it for such reduction. Such a certificate as to any additional
amounts payable under this subsection submitted by the Bank (which certificate
shall include a description in reasonable detail of the basis for the
computation) to the Borrower shall be conclusive absent manifest error.

         2.9 Inability to Determine Interest Rate. Notwithstanding any other
provision of this Agreement, if (i) the Bank shall reasonably determine (which
determination shall be conclusive and binding absent manifest error) that, by
reason of circumstances affecting the relevant market, reasonable and adequate
means do not exist for ascertaining LIBOR for


                                       7
<PAGE>

such Interest Period, or (ii) the Bank shall reasonably determine (which
determination shall be conclusive and binding absent manifest error) that the
LIBOR Rate does not adequately and fairly reflect the cost of funding LIBOR Rate
Loans, the Bank shall forthwith give telephone notice of such determination,
confirmed in writing, to the Borrower, and thereafter the right to request and
continue Loans as LIBOR Rate Loans shall be suspended until such time as the
conditions giving rise to such notice shall no longer exist. In the event LIBOR
Rate Loans are not available on account of operation of this Section, the Bank
will endeavor to provide an alternative index or reference rate.

         2.10 Illegality. Notwithstanding any other provision of this Agreement,
if the adoption of or any change in any Requirement of Law or in the
interpretation or application thereof, in each case occurring after the Closing
Date, by the relevant Governmental Authority shall make it unlawful for the Bank
to make or maintain LIBOR Rate Loans as contemplated by this Agreement or to
obtain in the interbank eurodollar market through its LIBOR Lending Office the
funds with which to make such Loans, (a) the Bank shall promptly notify the
Borrower thereof, (b) the commitment of the Bank hereunder to make LIBOR Rate
Loans or continue LIBOR Rate Loans as such shall forthwith be suspended until
the Bank shall give notice that the condition or situation which gave rise to
the suspension shall no longer exist, and (c) Loans then outstanding as LIBOR
Rate Loans, if any, shall be converted on the last day of the Interest Period
for such Loans or within such earlier period as required by law to Prime Loans.
The Borrower hereby agrees promptly to pay the Bank, upon its demand, any
additional amounts necessary to compensate the Bank for actual and direct costs
(but not including anticipated profits) reasonably incurred in making any
repayment in accordance with this subsection including, but not limited to, any
interest or fees payable by the Bank to lenders of funds obtained by it in order
to make or maintain its LIBOR Rate Loans hereunder. A certificate as to any
additional amounts payable pursuant to this subsection submitted by the Bank, to
the Borrower shall be conclusive in the absence of manifest error.

         2.11 Requirements of Law. If the adoption of or any change in any
Requirement of Law or in the interpretation or application thereof or compliance
by the Bank with any request or directive (whether or not having the force of
law) from any central bank or other Governmental Authority, in each case made
subsequent to the date hereof:

                  (i) shall subject the Bank to any tax of any kind whatsoever
         with respect to any LIBOR Rate Loan made by it, or change the basis of
         taxation of payments to the Bank in respect thereof (except for changes
         in the rate of tax on the net income or franchise tax applicable to the
         Bank);

                  (ii) shall impose, modify or hold applicable any reserve,
         special deposit, compulsory loan or similar requirement against assets
         held by, deposits or other liabilities in or for the account of,
         advances, loans or other extensions of credit by, or any other
         acquisition of funds by, any office of the Bank which is not otherwise
         included in the determination of the LIBOR Rate hereunder; or

                  (iii) shall impose on the Bank any other condition (excluding
         any tax of any kind whatsoever);

                                       8
<PAGE>

and the result of any of the foregoing is to increase the cost to the Bank of
making or maintaining LIBOR Loans or to reduce any amount receivable hereunder
or under the Note, then, in any such case, the Borrower shall promptly pay the
Bank, within 15 days after its demand, any additional amounts necessary to
compensate the Bank for such additional cost or reduced amount receivable as
determined by the Bank with respect to its LIBOR Rate Loans. A certificate as to
any additional amounts payable pursuant to this subsection submitted by the
Bank, describing in reasonable detail the nature of such event and a reasonably
detailed explanation of the calculation thereof, to the Borrower shall be
conclusive in the absence of manifest error.

         2.12 Indemnity. The Borrower hereby agree to indemnify the Bank and to
hold the Bank harmless from any funding loss or expense which the Bank may
sustain or incur (other than as a result of and to the extent the Bank's gross
negligence or willful misconduct) as a consequence of (a) default by the
Borrower in payment of the principal amount of or interest on any LIBOR Rate
Loan by the Bank in accordance with the terms hereof, (b) default by the
Borrower in accepting a LIBOR Rate Loan after the Borrower has given a notice in
accordance with the terms hereof, (c) default by the Borrower in making any
prepayment of a LIBOR Rate Loan after the Borrower has given a notice in
accordance with the terms hereof, and/or (d) the making by the Borrower of a
prepayment of a LIBOR Rate Loan, or the conversion thereof, on a day which is
not the last day of the Interest Period with respect thereto, in each case equal
to (i) the amount of interest which would have accrued on the amount so prepaid,
or not so paid, borrowed, converted or continued, for the period from the date
of such prepayment or of such failure to borrow, convert or continue to the last
day of such Interest Period (or, in the case of a failure to pay, borrow,
convert or continue, the Interest Period that would have commenced on the date
of such failure), in each case at the applicable rate of interest for such Loans
provided for herein (exclusive of any margin), over (ii) the amount of interest
(as reasonably determined by the Bank) which would have accrued to the Bank on
such amount by placing such amount on deposit for a comparable period with
leading banks in the interbank eurodollar market. A certificate as to any
additional amounts payable pursuant to this subsection submitted by the Bank, to
the Borrower shall be conclusive in the absence of manifest error.

         2.13 Taxes. All payments made by the Borrower hereunder or under any
Note will be made free and clear of, and without deduction or withholding for,
any present or future taxes, levies, imposts, duties, fees, assessments or other
charges of whatever nature now or hereafter imposed by any Governmental
Authority or by any political subdivision or taxing authority thereof or therein
with respect to such payments (but excluding (i) any tax imposed on or measured
by the net income or profits of a Lender pursuant to the laws of the
jurisdiction in which it is organized or the jurisdiction in which the principal
office or applicable lending office of the Bank is located or any subdivision
thereof or therein and (ii) any franchise taxes, branch taxes, taxes on doing
business or taxes on the overall capital or net worth of the Bank pursuant to
the laws of the jurisdiction in which it is organized or the jurisdiction in
which the principal office or its applicable lending office is located or any
subdivision thereof or therein) and all interest, penalties or similar
liabilities with respect thereto (all such non-excluded taxes, levies, imposts,
duties, fees, assessments or other charges being referred to collectively as
"Taxes"). If any Taxes are so levied or imposed, the Borrower agrees to pay the
full amount of such Taxes, and such additional amounts as may be necessary so
that every payment of all amounts due under this Agreement or under any Note,
after withholding or deduction for or on account of any such Taxes, will not be


                                       9
<PAGE>

less than the amount provided for herein or in such Note. The Borrower will
furnish to the Bank as soon as practicable after the date the payment of any
Taxes is due pursuant to applicable law certified copies (to the extent
reasonably available and required by law) of tax receipts evidencing such
payment by the Borrower. The Borrower agrees to indemnify and hold harmless, and
reimburse, the Bank upon its written request, for the amount of any Taxes so
levied or imposed and paid by the Bank. The agreements in this subsection shall
survive termination of this Agreement and payment of the Notes and all other
amounts payable hereunder.

         2.14 Payments and Computations. Payments shall be made hereunder in
U.S. dollars in immediately available funds, without offset, deduction,
counterclaim or withholding of any kind at the offices of the Bank provided in
the notice section hereof. Payments received after 2:00 P.M. (Charlotte, North
Carolina time) will be given credit the next following Business Day.
Computations of interest hereunder shall be made on the basis of actual number
of days elapsed over a year of 360 days.

         SECTION 3.  GUARANTY

         3.1 Guaranty. Each of the Guarantors hereby jointly and severally
guarantees to the Bank as hereinafter provided the prompt payment of the
Guaranteed Obligations in full when due (whether at stated maturity, as a
mandatory prepayment, by acceleration or otherwise and after giving effect to
any grace periods) strictly in accordance with the terms hereof. Each of the
Guarantors hereby further agrees that if any of the Guaranteed Obligations are
not paid in full when due (whether at stated maturity, as a mandatory
prepayment, by acceleration or otherwise and after giving effect to any grace
periods), the Guarantor will promptly pay the same, without any demand or notice
whatsoever, and that in the case of any extension of time of payment or renewal
of any of the Guaranteed Obligations, the same will be promptly paid in full
when due (whether at extended maturity, as a mandatory prepayment, by
acceleration or otherwise and after giving effect to any grace periods) in
accordance with the terms of such extension or renewal. This is a guaranty of
payment and not of collection.

         Notwithstanding any provision to the contrary contained herein or in
any other of the Credit Documents, to the extent the obligations of any
Guarantor as guarantor hereunder shall be adjudicated to be invalid or
unenforceable for any reason (including, without limitation, because of any
applicable state or federal law relating to fraudulent conveyances or transfers)
then the obligations of such Guarantor hereunder shall be limited to the maximum
amount that is permissible under applicable law (whether federal or state and
including, without limitation, the Bankruptcy Code).

         3.2 Obligations Unconditional. The obligations of the Guarantors under
Section 3.1 hereof are absolute and unconditional, irrespective of the value,
genuineness, validity, regularity or enforceability of this Agreement or the
Note, or any other agreement or instrument referred to herein or therein or
relating hereto or thereto, or any substitution, release or exchange of any
other guarantee of or security for any of the Guaranteed Obligations, and, to
the fullest extent permitted by applicable law, irrespective of any other
circumstance whatsoever which might otherwise constitute a legal or equitable
discharge or defense of a surety or guarantor, it being the intent of this
Section 3.2 that the obligations of the Guarantors hereunder shall be absolute
and unconditional under any and all


                                       10
<PAGE>

circumstances. Each of the Guarantors agrees that it shall have no right of
subrogation, indemnity, reimbursement or contribution against the Borrower or
any other guarantor for amounts paid under this Guaranty until such time as the
Bank has been paid in full, all commitments, if any, have been terminated and no
Person or Governmental Authority shall have any right to request any return or
reimbursement of funds from the Bank in connection with monies received under
the Credit Documents. Without limiting the generality of the foregoing, it is
agreed that, to the fullest extent permitted by law, the occurrence of any one
or more of the following shall not alter or impair the liability of the
Guarantors hereunder which shall remain absolute and unconditional as described
above:

                  (i) at any time or from time to time, without notice to the
         Guarantors, the time for any performance of or compliance with any of
         the Guaranteed Obligations shall be extended, or such performance or
         compliance shall be waived;

                  (ii) any of the acts mentioned in any of the provisions of
         this Agreement or the Note or any other agreement or instrument
         referred to herein or therein or relating hereto or thereto shall be
         done or omitted;

                  (iii) the maturity of any of the Guaranteed Obligations shall
         be accelerated, or any of the Guaranteed Obligations shall be modified,
         supplemented or amended in any respect, or any right under any of the
         Credit Documents or any other agreement or instrument referred to in
         the Credit Documents shall be waived or any other guarantee of any of
         the Guaranteed Obligations or any security therefor shall be released
         or exchanged in whole or in part or otherwise dealt with;

                  (iv) any Lien granted to, or in favor of, the Bank as security
         for any of the Guaranteed Obligations shall fail to attach or be
         perfected or shall be released or discharged in whole or in part; or

                  (v) any of the Guaranteed Obligations shall be determined to
         be void or voidable (including, without limitation, for the benefit of
         any creditor of any Guarantor or any other guarantor) or shall be
         subordinated to the claims of any Person (including, without
         limitation, any creditor of any guarantor).

With respect to its obligations hereunder, each of the Guarantors hereby
expressly waives diligence, presentment, demand of payment, protest and all
notices whatsoever, and any requirement that the Bank exhaust any right, power
or remedy or proceed against any Person under this Agreement or the Note or any
other agreement or instrument referred to herein or therein or relating hereto
or thereto, or against any other Person under any other guarantee of, or
security for, any of the Guaranteed Obligations.

         3.3 Reinstatement. The obligations of the Guarantors under this Section
3 shall be automatically reinstated if and to the extent that for any reason any
payment by or on behalf of any Person in respect of the Guaranteed Obligations
is rescinded or must be otherwise restored by any holder of any of the
Guaranteed Obligations, whether as a result of any proceedings in bankruptcy or
reorganization or otherwise, and each of the Guarantors agrees that it will
indemnify the Bank on demand for all reasonable costs and expenses (including,
without limitation, fees and expenses of counsel) incurred by the Bank in
connection with such rescission or restoration, including any such costs and
expenses incurred in defending


                                       11
<PAGE>

against any claim alleging that such payment constituted a preference,
fraudulent transfer or similar payment under any bankruptcy, insolvency or
similar law.

         3.4 Certain Additional Waivers. Without limiting the generality of the
provisions of this Section 3, each of the Guarantors hereby specifically waives
the benefits of N.C. Gen. Stat. Sec. 26-7 through 26-9, inclusive. Each of the
Guarantors agrees that it shall have no right of recourse to security for the
Guaranteed Obligations, except through the exercise of the rights of subrogation
pursuant to Section 3.2.

         3.5 Remedies. Each of the Guarantors agrees that, to the fullest extent
permitted by law, as between the Guarantors, on the one hand, and the Bank, on
the other hand, the Guaranteed Obligations may be declared to be forthwith due
and payable as provided in Section 7.2 hereof (and shall be deemed to have
become automatically due and payable in the circumstances provided in said
Section 7.2) for purposes of Section 3.1 hereof notwithstanding any stay,
injunction or other prohibition preventing such declaration (or preventing the
Guaranteed Obligations from becoming automatically due and payable) as against
any other Person and that, in the event of such declaration (or the Guaranteed
Obligations being deemed to have become automatically due and payable), the
Guaranteed Obligations (whether or not due and payable by any other Person)
shall forthwith become due and payable by the Guarantors for purposes of said
Section 3.1.

         3.6 Continuing Guarantee. The guarantee in this Section 3 is a
continuing guarantee, and shall apply to all Guaranteed Obligations whenever
arising.

         3.7 Rights of Contribution. The Guarantors hereby agree, as among
themselves, that if any Guarantor shall become an Excess Funding Guarantor (as
defined below), each other Guarantor shall, on demand of such Excess Funding
Guarantor (but subject to the succeeding provisions of this Section), pay to
such Excess Funding Guarantor an amount equal to such Guarantor's Pro Rata Share
(as defined below and determined, for this purpose, without reference to the
properties, assets, liabilities and debts of such Excess Funding Guarantor) of
such Excess Payment (as defined below). The payment obligation of any Guarantor
to any Excess Funding Guarantor under this Section shall be subordinate and
subject in right of payment to the prior payment in full of the obligations of
such Guarantor under the other provisions of this Section 3, and such Excess
Funding Guarantor shall not exercise any right or remedy with respect to such
excess until payment and satisfaction in full of all of such obligations. For
purposes hereof, (i) "Excess Funding Guarantor" shall mean, in respect of any
obligations arising under the other provisions of this Section 3 (hereafter, the
"Guarantied Obligations"), a Guarantor that has paid an amount in excess of its
Pro Rata Share of the Guarantied Obligations; (ii) "Excess Payment" shall mean,
in respect of any Guarantied Obligations, the amount paid by an Excess Funding
Guarantor in excess of its Pro Rata Share of such Guarantied Obligations; and
(iii) "Pro Rata Share", for the purposes of this Section, shall mean, for any
Guarantor, the ratio (expressed as a percentage) of (a) the amount by which the
aggregate present fair saleable value of all of its assets and properties
exceeds the amount of all debts and liabilities of such Guarantor (including
contingent, subordinated, unmatured, and unliquidated liabilities, but excluding
the obligations of such Guarantor hereunder) to (b) the amount by which the
aggregate present fair saleable value of all assets and other properties of the
Borrower and all of the Guarantors exceeds the amount of all of the debts and
liabilities (including contingent, subordinated, unmatured, and unliquidated
liabilities, but excluding the obligations of the Borrower and the Guarantors


                                       12
<PAGE>

hereunder) of the Borrower and all of the Guarantors, all as of the Closing Date
(if any Guarantor becomes a party hereto subsequent to the Closing Date, then
for the purposes of this Section such subsequent Guarantor shall be deemed to
have been a Guarantor as of the Closing Date and the information pertaining to,
and only pertaining to, such Guarantor as of the date such Guarantor became a
Guarantor shall be deemed true as of the Closing Date).

         3.8 Joinder of Additional Guarantors. The Borrower may join additional
subsidiaries as Guarantors hereunder by way of execution of a Joinder Agreement,
a form of which is attached as Annex B.

                                February __, 1999


First Union National Bank
Raleigh, North Carolina

         Re:      $8 million Loan Agreement dated as of the date hereof (the
                  "Loan Agreement") among PPGx, Inc., a Delaware corporation,
                  the Guarantors identified therein and First Union National
                  Bank. Terms used but not otherwise defined shall have the
                  meanings provided in the Loan Agreement.

Ladies and Gentlemen:

         I have acted as counsel to PPGx, Inc., Delaware corporation (the
"Borrower"), Pharmaceutical Product Development, Inc., a North Carolina
corporation, and those subsidiaries of the Borrower which are Guarantors under
the Loan Agreement identified on Schedule A attached hereto (collectively with
the Borrower, the "Credit Parties"), in connection with the execution and
delivery by them of the Loan Agreement.

         This opinion is given in accordance with the requirements of Section
4.1(b) of the Loan Agreement.

         We have participated in the preparation of the Loan Agreement and the
other Credit Documents, and have examined copies of each of the foregoing
documents executed by the Credit Parties. We have also examined such
certificates, documents and records, and have made such examination of law, as
we have deemed necessary to enable us to render the opinions expressed below. In
addition, we have examined and relied as to matters of fact upon representations
and warranties contained in the Credit Documents and in certificates, copies of
which have been furnished to you, in connection with the Credit Documents.

         For purposes of paragraph 4 below, we have assumed that the Credit
Documents are the legal, valid and binding obligations of the parties thereto
other than the Credit Parties, enforceable against them in accordance with their
respective terms.

         The opinions expressed below are limited to matters governed by the
internal laws of the State of North Carolina, the General Corporation Law of the
State of Delaware and the federal laws of the United States of America.

         Whenever the phrase "to the best of our knowledge" is used herein, it
refers to the actual knowledge of the attorneys of this firm involved in the
representation of the Credit Parties without further investigation.

         Based on the foregoing, and subject to the qualifications stated
herein, we are of the opinion that:


<PAGE>

         1. Each of the Credit Parties is a corporation duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
incorporation, as identified on Schedule A attached hereto, and is qualified to
carry on its business in the manner as contemplated under the Credit Documents
and as now conducted.

         2. Each of the Credit Parties has all requisite corporate power and
authority, and the legal right, to make, execute, deliver and perform the Loan
Agreement and the other Credit Documents to which it is a party and to borrow
and accept extensions of credit or give a guaranty in respect thereof, as
appropriate, and has taken all necessary corporate action to authorize the
execution, delivery and performance of the Loan Agreement and the other Credit
Documents to which it is a party.

         3. No consent or authorization of, filing with, notice to or other
similar act by or in respect of, any federal court or Governmental Authority or
any other Person is required to be obtained or made by or on behalf of any
Credit Party on or prior to the date hereof in connection with the execution,
delivery or performance of the Credit Documents, except for such consents,
approvals, authorizations or other actions as have been obtained or made.

         4. To the best of our knowledge, no claim, litigation or proceeding
before any arbitrator or Governmental Authority is pending or threatened which
if adversely determined would reasonably be expected to have a material adverse
effect on the Borrower and its subsidiaries taken as a whole.

         5. The Loan Agreement, and each of the other Credit Documents to which
it is a party, have been duly executed and delivered by each Credit Party and
constitute the legal, valid and binding obligations of each Credit Party,
enforceable in accordance with their respective terms, except as such
enforceability may be limited by bankruptcy, insolvency, reorganization,
moratorium or similar laws affecting the enforceability of creditors' rights
generally and by general equitable principles (whether enforcement is sought by
proceedings in equity or at law).

         6. The execution, delivery and performance by each Credit Party of the
Loan Agreement and the other Credit Documents to which it is a party, the
borrowings and guaranties thereunder and the use of the proceeds thereof will
not violate or otherwise contravene the articles of incorporation or bylaws of
any of the Credit Parties or any Requirement of Law or, to the best of our
knowledge, any Contractual Obligation of any of the Credit Parties.

         The opinions expressed herein do not purport to cover, and we express
no opinion with respect to, the applicability of Section 548 of the federal
Bankruptcy Code or any comparable provision of state law, including the
provisions relating to fraudulent conveyances. We call your attention to the
fact that certain cases have held that an obligation of a corporation incurred
to purchase such corporation's stock is subordinate to the claims of general
creditors upon the bankruptcy or insolvency of the corporation. In addition, we
express no opinion as to whether a subsidiary may guarantee, become a joint and
several obligor or otherwise become liable for, or pledge its assets to secure,
indebtedness incurred by its parent or another subsidiary of its parent except
to the extent

<PAGE>

such subsidiary may be determined to have benefited from the incurrence of such
indebtedness by its parent or such other subsidiary, or as to whether such
benefit may be measured other than by the extent to which the proceeds of the
indebtedness incurred by its parent or such other subsidiary are directly or
indirectly made available to such subsidiary for its corporate purposes.

         This opinion is rendered solely for your benefit, and the benefit of
your successors and assigns, in connection with the transactions described
above. This opinion may not be used or relied upon by any other person without
our prior written consent.

                                              Very truly yours,


                                              /s/ Fred B. Davenport, Jr.
                                                   Counsel to the Borrower

                  NOW, THEREFORE, in consideration of the foregoing recitals,
the mutual covenants and agreements contained herein, and for other good and
valuable consideration, the sufficiency and receipt of which are hereby
acknowledged, the parties agree as follows:

                  1. Purchase and Sale of Shares. Subject to the terms and
conditions of this Agreement, the Corporation agrees to sell and issue to PPD

Shares, PPD agrees to execute and have the Shares subject to the terms of an
Investors' Rights Agreement ("Investors' Rights Agreement") in the form of
Exhibit A attached hereto and incorporated herein by reference.

                  2. Purchase Price. The purchase price to be paid by PPD in
exchange for the issuance of the Shares shall be as follows:

Corporation of all of PPD's rights, title and interest in and to that certain
Software License Agreement dated February 1, 1999 between PPD and Axys
Pharmaceuticals, Inc., a Delaware corporation ("Axys"). Such assignment shall be

License Agreement in the form of Exhibit C attached hereto and incorporated
herein by reference.

                  3. Closing. The closing of the transactions contemplated by
this Agreement (the "Closing") shall occur contemporaneously with the execution
of this Agreement and shall be effective as of the date of this Agreement (the
"Closing Date").

                  4. Representations, Warranties and Covenants of the
Corporation. The Corporation represents and warrants to PPD and covenants with
PPD that as of the date of Closing:

                           a. Organization and Standing of the Corporation. The
Corporation is duly organized and validly existing and has complied with all
requirements to continue its existence under the laws of the State of Delaware,
and has the corporate power and authority to own, lease and use its properties
and to transact its business where and as now conducted.

                           b. Capitalization. The authorized capital stock of
the Corporation consists of Fifteen Million shares (15,000,000) of common stock,
$.001 par value per share (the "Common Stock"), and Ten Million (10,000,000)
shares of Preferred Stock, $.001 par value per share (the "Preferred Stock"), of
which Ten Million (10,000,000) shares of the Preferred Stock have been
designated as Series A Preferred Stock. After giving effect to the sale and
issuance of the Shares to PPD as contemplated by this Agreement and after giving
effect to the sale and issuance of shares of Preferred Stock and Common Stock to
Axys pursuant to a Stock Purchase Agreement dated an even date herewith, both of
which are to be closed contemporaneously, one thousand (1,000) of the shares of
the Common Stock shall be issued and outstanding and all of the Preferred Stock
shall be issued and outstanding such that, upon issuance to PPD, the Shares
shall represent Eighteen percent (18%) of all of the issued and outstanding
shares of capital stock, both the Common Stock and Preferred Stock, of the
Corporation as of the Closing. None of the Shares are being issued in violation
of the preemptive or other rights of any person.

                           c. Execution and Delivery Authorized. The execution
and delivery of this Agreement, the issuance of the Shares to PPD, the adequacy
of the consideration paid in exchange for the Shares under applicable law and
the consummation of the transactions contemplated by this Agreement have been
duly authorized and approved by the board of directors of the Corporation.

                           d. Validity of Agreement. The execution and
performance of this Agreement and the actions provided for or contemplated
hereunder will not violate the provisions of any agreement, instrument or
obligation to which the Corporation is a party or by which it is bound. Assuming
due authorization, execution and delivery hereof by PPD, this Agreement
constitutes the valid and binding agreement of the Corporation, enforceable
against the Corporation

                                       2
<PAGE>

in accordance with its terms, subject as to enforceability to general equitable
principles and to the laws of bankruptcy, insolvency or similar laws governing
the rights of creditors.

                           e. Title to Shares. Upon issuance to PPD, the Shares
shall be free and clear from any liens, claims, restrictions or encumbrances of
any kind or nature whatsoever, except for: (i) such restrictions contained in
the Certificate of Incorporation or the Bylaws of the Corporation, as now in
existence or hereafter amended in accordance with their respective terms, (ii)
the terms and restrictions contained in the Investors' Rights Agreement attached
hereto as Exhibit A, and (iii) any restrictions upon transfer arising under
federal or state securities laws. The Corporation is not a party to or bound by
any agreement, instrument, trust, proxy or understanding restricting or
otherwise binding the ownership, transfer or voting of any of the Shares other
than the Investors' Rights Agreement. Upon payment of the purchase price by PPD
and issuance of the Shares to PPD, the Shares will be validly issued and will be
fully paid and nonassessable.

                           f. Certificate of Incorporation and Bylaws. True and
complete copies of the Certificate of Incorporation and Bylaws of the
Corporation, as currently in force, have been delivered to PPD. The Certificate
of Incorporation and Bylaws have not been and will not be amended prior to the
Closing.

                  5. Representations, Warranties and Covenants of PPD. PPD
represents and warrants to the Corporation and covenants with the Corporation
that as of the date of Closing:

                           a. Organization and Standing of PPD. PPD is duly
organized and validly existing and has complied with all requirements to
continue its existence under the laws of the State of North Carolina, and has
the corporate power and authority to own, lease and use its properties and to
transact its business where and as now conducted.

                           b. Execution and Delivery Authorized. The execution
and delivery of this Agreement and the consummation of the transactions
contemplated by this Agreement have been duly authorized by the board of
directors of PPD.

                           c. Validity of Agreement. The execution and
performance of this Agreement and the actions provided for or contemplated
hereunder will not violate the provisions of any agreement, instrument or
obligation to which PPD is a party or by which it is bound. Assuming due
authorization, execution and delivery hereof by the Corporation, this Agreement
constitutes the valid and binding agreement of PPD, enforceable against PPD in
accordance with its terms, subject as to enforceability to general equitable
principles and to the laws of bankruptcy, insolvency or similar laws governing
the rights of creditors.

                           d. Access and Information. PPD and its
representatives have been afforded full and free access to the Corporation's
financial statements and other information concerning the Corporation and PPD
has been afforded an opportunity to ask such questions of the Corporation's
officers, employees, agents, accountants and representatives concerning the
Corporation's business, prospects, operations, financial condition, assets,
liabilities and other


                                       3
<PAGE>

relevant matters, including the rights, preferences and limitations of the
Shares, as PPD deems necessary or desirable and has been given all such
information as has been requested, in order to evaluate the merits and risks
associated with holding the Shares. PPD has conducted its own "due diligence"
investigation of the Corporation and its management and business, and its own
analysis of the merits and risks of holding the Shares, and its own analysis of
the fairness and desirability of the terms governing the purchase of the Shares.
PPD is familiar with the business conducted by the Corporation and has such
knowledge and experience in financial and business matters that PPD is capable
of evaluating the merits and risks of the purchase of the Shares pursuant to the
terms of this Agreement and of protecting PPD's interests in connection
therewith.

                           e. Investment Intent of PPD. The Shares are being
acquired by PPD for its own account and not with a view to, or for resale in
connection with, any distribution or public offering thereof within the meaning
of the Securities Act of 1933, as amended (the "Securities Act"). PPD
understands that the Shares have not been, and will not be, registered under the
Securities Act by reason of their issuance in a transaction exempt from the
registration requirements of the Securities Act, that the Corporation has no
present intention of registering the Shares, that the Shares must be held by PPD
indefinitely, and that PPD must therefore bear the economic risk associated with
holding the Shares indefinitely, unless a subsequent disposition thereof is
exempt from registration. PPD is able to bear the economic risk of holding the
Shares pursuant to the terms of this Agreement. In addition to any other legends
required by the Investors' Rights Agreement, each certificate evidencing the
Shares shall be endorsed with the following legend:

                  THE SHARES OF STOCK EVIDENCED BY THIS CERTIFICATE HAVE NOT
                  BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED
                  (THE "SECURITIES ACT"), OR THE SECURITIES LAWS OF ANY STATE,
                  AND MAY NOT BE SOLD, OFFERED FOR SALE, ASSIGNED, MORTGAGED,
                  PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED WITHOUT AN
                  EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT
                  COVERING SUCH SHARES, AND ANY APPLICABLE STATE SECURITIES
                  LAWS, OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE
                  CORPORATION THAT THE TRANSACTION SHALL NOT RESULT IN A
                  VIOLATION OF FEDERAL OR STATE SECURITIES LAWS.

PPD acknowledges that no public market now exists for the Shares and that there
can be no assurance that any public market will exist in the future. PPD
understands that the Shares will constitute "restricted securities", and under
the Securities Act and applicable regulations the Shares may be resold without
registration under the Securities Act only in certain limited circumstances. In
this connection, PPD represents that it is familiar with Rule 144 under the
Securities Act and understands the resale limitations imposed thereby and the
Securities Act.

                                       4
<PAGE>

                           f. Accredited Investor Status. PPD represents and
warrants that it is an "accredited investor" as defined in Rule 501 of
Regulation D promulgated under the Securities Act.

                  6. Additional Agreements. In addition to any other covenants
and agreements of the parties set forth in this Agreement, the parties hereby
agree as follows:

                           a. Transfer of Employees by PPD. PPD agrees to use
its reasonable best efforts to cause the full time employees with PPD Pharmaco,
Inc., a Texas corporation, listed on Schedule 6.a. to accept employment with the
Corporation as of the Closing Date and to cause all of the current employees of
Intek and Intek Labs Limited, a wholly owned subsidiary of Intek , (except for
Richard B. Sheridan III and Rosalee Chingara, both of whom shall resign as
employees of Intek or Intek Labs Limited, as applicable effective as of the
Closing and PPGx shall have no obligation to pay such employees any severance
payments or benefits) to continue employment with Intek or Intek Labs Limited,
as applicable, as of the Closing Date. The Corporation agrees to offer
employment to any of such employees willing to accept such offer of employment
(or to offer terms of continued employment with Intek, in the case of Intek
employees) upon such terms and conditions as are mutually acceptable to the
Corporation and each of such employees.

                           b. Distributor Agreement. At Closing, PPD, or an
affiliate of PPD, and the Corporation shall execute a Distributor Agreement in
the form of Exhibit D attached hereto and incorporated herein by reference.

                           c. Lease Assignments/Subleases. At Closing, PPD shall
cause its subsidiary, Belmont Research, Inc., to enter into a Sublease with the
Corporation for a portion of the building known as the Brickyard Office Park at
84 Sherman Street, Cambridge, Massachusetts (the "Sublease"). In addition, PPD
and the Corporation shall execute at Closing a letter agreement (the "Letter
Agreement") related to the leasing of space at Research Triangle Park, North
Carolina, Cambridge, United Kingdom and Philadelphia, Pennsylvania. The Sublease
and the Letter Agreement shall be upon terms and conditions mutually acceptable
to PPD and the Corporation.

                  7. Conditions to PPD's Obligation to Close. The obligations of
PPD under this Agreement are subject to the satisfaction, or the waiver thereof
by PPD, of the following express conditions precedent on or before the Closing
Date:

                           a. Correctness of Warranties. All of the
representations and warranties of the Corporation contained in this Agreement
were true and correct when made and shall be true and correct at and as of the
Closing Date (except such representations, warranties and matters which are
specifically limited by reference to an earlier date and were true and correct
as of such earlier date).

                           b. Performance of Obligations. The Corporation has
performed and complied with all of the obligations, covenants and conditions
required to be performed or complied in all material respects with by it at or
prior to the Closing.

                           c. No Adverse Change. There shall have been no
material adverse change in the prospects for the business contemplated to be
conducted by the Corporation.

                           d. Documents to be Delivered by the Corporation at

third party claim.

         8.3 LIMITATION ON INDEMNITY. Neither Party shall be entitled to
indemnification under this Article 8, notwithstanding any other provision hereof
to the contrary, to the extent that the events giving rise to the claim for

directors, employees or agents.

9.       LIMITATION OF LIABILITY. Neither Party shall be liable to the other
Party or any third party for any loss of use, interruption of business or any
indirect, special, incidental or consequential damages of any kind (including
lost profits) regardless of the form of action whether in contract, tort
(including negligence), strict product liability or otherwise, arising out of
this Agreement or the existence, furnishing, functioning or use of or inability
to use the Axys Software or Database, or to any third party with respect
thereto, even if such Party has been advised of the possibility of such damages.
In no event shall either Party's liability under this


                                       8

Agreement, whether in contract, tort (including negligence) or otherwise, exceed
the license fee paid by Licensee hereunder. The foregoing limitations shall
apply even if the above stated warranties fail of their essential purpose.
Notwithstanding the foregoing, Licensee's limitation of liability hereunder

10.      CONFIDENTIALITY.

         10.1 CONFIDENTIALITY. During the term of this Agreement and thereafter,
each Party hereto will maintain in confidence all Confidential Information
disclosed by the other Party hereto. Neither Party will use, disclose or grant
use of such Confidential Information except as expressly authorized by this
Agreement. To the extent that disclosure is authorized by this Agreement, the
disclosing Party will obtain prior agreement from its employees, agents or
consultants to whom disclosure is to be made to hold in confidence and not make
use of such information for any purpose other than those permitted by this
Agreement. Each Party will use at least the same standard of care as it uses to
protect its own Confidential Information to ensure that such employees, agents
or consultants do not disclose or make any unauthorized use of such Confidential
Information. Each Party will promptly notify the other Party upon discovery of
any unauthorized use or disclosure of the Confidential Information.

         10.2 AXYS SOFTWARE AND DATABASE CONFIDENTIALITY. Axys hereby agrees to
(i) maintain the Axys Software and Database as its Confidential Information;
(ii) to obtain prior agreement from any third parties to whom disclosure is made
to hold such Confidential Information in confidence and not make use of such
Confidential Information for any unauthorized purpose; and (iii) to use at least
the same standard of care and due diligence Axys uses to protect its other
Confidential Information which Axys has disclosed to third parties to ensure
that such third parties do not disclose or make any unauthorized use of the Axys
Software and Database.

         10.3 EXCEPTIONS. Notwithstanding the other provisions of this
Agreement, nothing received by the receiving Party will be considered to be the

the public other than by a breach of this Agreement;

                  (B) It has been rightfully received by the receiving Party
from a third party without confidential limitations;

                  (C) It has been independently developed for the receiving

Confidential Information; or

                  (D) It was known to the receiving Party prior to its first
receipt from the disclosing Party.

                  (B) Licensee may terminate this Agreement upon thirty (30)

recovery of money damages would be inadequate, if such breach is not cured
within such thirty (30) day period or, if such breach cannot reasonably be
expected to be cured within such thirty (30) day period, Axys has not commenced
within such thirty (30) day period best efforts to effect such cure as promptly
as possible and has not continued to use its best efforts in the exercise of
prudent business judgment until such cure is effected; provided that in no event
shall the period in which to cure such breach exceed one hundred eighty (180)

                  (C) EXISTING SUBLICENSES. Termination of this Agreement and

12.      GENERAL PROVISIONS.

         12.1 NO AGENCY. Each Party shall act solely as an independent
contractor and nothing in this Agreement shall be construed to give either Party
the power or authority to act for, bind or commit the other Party in any way.
Nothing herein shall be construed to create the relationship of partnership,
principal and agent or joint venture between the Parties.

         12.2 GOVERNING LAW. This Agreement shall be governed by the laws of the
State of Delaware that apply to contracts negotiated, executed and performed
within the State of Delaware.

         12.3 NOTICES. All notices permitted or required under this Agreement
shall be in writing and shall be delivered by registered or certified mail,
return receipt requested, to the address set forth in the first paragraph of
this Agreement or delivered by hand. All notices shall be deemed to have been
given two days after such notice is mailed, as evidenced by the postmark at the
point of mailing or on the date of personal delivery, if not mailed. If the
notice is to Axys, a copy shall also be sent to its General Counsel.

         12.4 INJUNCTIVE RELIEF. It is understood and agreed that,
notwithstanding any other provision of this Agreement, breach of the provisions
of this Agreement regarding the protection of Confidential Information by
Licensee will cause Axys irreparable damage for which recovery of money damages
would be inadequate, and that Axys shall therefore be entitled to seek timely
injunctive relief to protect Axys' rights under this Agreement in addition to
any and all remedies available at law.

         12.5 WAIVER. The failure of either Party to require performance by the
other Party of any provision hereof shall not affect the full right to require
such performance at any time thereafter; nor shall the waiver by either Party of
a breach of any provision hereof be taken or held to be a waiver of the
provision itself.

         12.6 SEVERABILITY. If a court of competent jurisdiction declares any
provision of this Agreement invalid or unenforceable, or if any government or
other agency having jurisdiction over either Axys or Licensee deems any
provision to be contrary to any laws, then that provision shall be severed and
the remainder of the Agreement shall continue in full force and effect. The
Parties further agree to discuss in good faith an amendment to replace such
void, invalid, unenforceable, or unlawful provision with a valid and enforceable
provision that will achieve, to the extent possible, the economic, business and
other purposes of such void, invalid, unenforceable or unlawful provision.

         12.7 HEADINGS. The section headings appearing in this Agreement are
inserted only as a matter of convenience and in no way define, limit, construe
or describe the scope or extent of such section, or in any way affect this
Agreement.

         12.8 COMPLIANCE WITH LAWS; EXPORT CONTROLS. Each Party agrees to comply
with all applicable laws, rules and regulations in connection with its
activities under this Agreement. Each Party further agrees that it will comply
with all U.S. export control laws and the applicable regulations thereunder, as
well as any other applicable laws of the U.S. affecting the export of
technology.

         12.9 ASSIGNMENT. Subsequent to the execution of this Agreement,
Licensee may assign this Agreement to PPGx, Inc. Upon such assignment, PPGx,
Inc. shall agree in writing to be bound by all of Licensee's obligations under
this Agreement; thereafter the term "Licensee" as used in this Agreement shall
be understood to mean PPGx, Inc., whose rights and obligations shall be governed
by this Agreement. Except as expressly set forth above, Licensee shall not


                                       11
<PAGE>

assign any rights or obligations arising under this Agreement without the prior
written consent of Axys. Notwithstanding the foregoing, PPGx, Inc. may assign
this Agreement to a third party in the event of a merger, acquisition,
reorganization or recapitalization by or of PPGx, Inc., upon written notice to
Axys. Subject to the above restrictions on assignment, this Agreement shall
inure to the benefit of and bind the successors and assigns of the Parties. Any
attempted assignment in derogation of the foregoing shall be void.

         12.10 U.S. GOVERNMENT SUBLICENSEES. The Axys Software and Database are
"commercial items," as defined at 48 C.F.R. 2.101 (Oct 1995), consisting of
"commercial computer software" and "commercial computer software documentation,"
as such terms are used in 48 C.F.R. 12.212 (Sep 1995). Consistent with 48 C.F.R.
12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (Jun 1995), Licensee will
provide the Axys Software and Database to U.S. Government sublicensees (i) only
as a commercial end item and (ii) with only those rights as are granted to all
other sublicensees pursuant to the terms and conditions of this Agreement.

         12.11 COUNTERPARTS. This Agreement may be executed in one or more
counterparts, each of which shall be an original and all of which shall
constitute together the same document.

         12.12 ENTIRE AGREEMENT. This Agreement and the Exhibits hereto
constitute the entire, final and complete agreement and understanding between
the Parties, and replaces and supersedes all prior discussions and agreements
between them, with respect to the subject matter hereof. No amendment,
modification or waiver of any terms or conditions hereof shall be effective
unless made in writing and signed by a duly authorized officer of each Party.

         IN WITNESS WHEREOF, the undersigned have caused this Agreement to be
executed by their respective authorized representatives. This Agreement may be

                           b. Execution and Delivery Authorized. The execution
and delivery of this Agreement and the consummation of the transactions
contemplated by this Agreement have been duly authorized by the board of
directors of PPD and by PPD as the sole shareholder of Intek. No approval of the
shareholders of PPD is required in connection with the execution and delivery of
this Agreement and the consummation of the transactions contemplated by this
Agreement.

                           c. Validity of Agreement. Except for customer
contracts of Intek which contain provisions requiring consent to change of
control, the execution and performance of this Agreement and the actions
provided for or contemplated hereunder will not violate the provisions of any
agreement, instrument or obligation to which either PPD or Intek is a party.
Assuming due authorization, execution and delivery hereof by the Corporation,
this Agreement constitutes the valid and binding agreement of PPD, enforceable
against PPD in accordance with its terms, subject as to enforceability to
general equitable principles and to the laws of bankruptcy, insolvency or
similar laws governing the rights of creditors.

                           d. Title to Intek Shares. The Intek Shares are now
and shall be, upon the Transfer, free and clear from any liens, claims,
restrictions or encumbrances of any kind or nature whatsoever, except for such
restrictions contained in the Articles of Incorporation or the Bylaws of Intek,
as now in existence or restrictions upon transfer arising under federal or state
securities laws. Neither PPD nor Intek is a party to or bound by any agreement,
instrument, trust, proxy or understanding restricting or otherwise binding the
ownership, transfer or voting of any of the Intek Shares. Upon completion of the
Transfer, the Intek Shares shall be validly issued and will be fully paid and
nonassessable.

                           e. Capitalization of Intek. Intek's entire authorized
capital stock consists solely of One hundred thousand (100,000) shares of common
stock, no par value per share, of which ten (10) shares are presently issued and
outstanding. As of the date of this Agreement, the Intek Shares comprise all of
the issued and outstanding shares of Intek. All of the issued and outstanding
shares of Intek have been duly authorized and validly issued, are fully paid and
are nonassessable. None of the outstanding shares of Intek were issued in
violation of the preemptive rights of any shareholder and none will be subject
to any preemptive or similar rights. There are no outstanding subscriptions,
options, warrants, contracts or any other commitments or rights (including
rights to distributions or payments) of any character with respect to, or
obligating Intek to issue any of, the authorized capital stock of Intek
(including the Intek Shares). Intek Lab's entire authorized share capital
consists of 50,000 ordinary shares, of which 1,500 comprise all of the issued

any property or assets of Intek, (ii) except as otherwise disclosed in this
Agreement, conflict with, result in any default under (with or without notice or

                                    (1) Filings. Intek has filed all Tax Returns
required to be filed before the Transfer Date. All such Tax Returns were correct
and complete in all material respects. All Taxes owed by Intek (whether or not
shown on any Tax Return) have been paid when due. Intek is not the beneficiary
of any extension of time within which to file any Tax Return. No claim has ever
been made by an authority in a jurisdiction where Intek does not file Tax
Returns that it is or may be subject to taxation by that jurisdiction. There are
no security interests on any of the assets of Intek that arose in connection
with any failure (or alleged failure) to pay any Tax.

                                    (2) Withholding. Except as described in
Schedule 3.m., Intek has withheld and paid all Taxes required to have been
withheld and paid in connection with amounts paid or owing to any employee,
independent contractor, creditor, stockholder, or other third party.

are no assessments or additional Taxes owing for any period for which Tax
Returns have been filed. There is no dispute or claim concerning any Tax
liability of Intek either (i) claimed or raised by any authority in writing or
(ii) as to which any of PPD and the directors and officers (and employees
responsible for Tax matters) of Intek has Knowledge based upon personal contact
with any agent of such authority. PPD has delivered to the Corporation correct
and complete in all material respects copies of all income Tax Returns,
examination reports, and statements of deficiencies assessed against or agreed
to by Intek for any Tax periods beginning on or after its incorporation on March
12, 1997.

                                    (4) Statutes of Limitation. Intek has not
waived any statute of limitations in respect of Taxes or agreed to any extension

did not, as of November 30, 1998 exceed the estimate for Tax liability set forth
on the face of the November 30, 1998 balance sheet or in notes thereto.

                           n. Financial Statements. PPD has furnished the

the Transfer Date any material adverse changes in the business or in the
condition (financial or otherwise) or the operations or prospects of Intek as a
whole not adequately disclosed on said Financial Statements.

                           o. Absence of Undisclosed Liabilities. Except as
disclosed on Schedule 3.o., Intek does not have any material liability or
obligation of any nature (whether accrued, fixed, contingent or otherwise),
including any liability to customers or suppliers, which is not fully disclosed,
reflected or adequately reserved against or otherwise provided for in its
Financial Statements. Except as specifically disclosed on Schedule 3.o., Intek
has not incurred since November 30, 1998 any material indebtedness, liabilities,
obligations or liens against its properties or assets.

                           p. Title to Properties. Except as disclosed in its
Financial Statements and except as listed on Schedule 3.p., Intek has good,
valid and marketable title to all of its respective properties and assets, real
and personal, tangible and intangible, which it purports to own and use in
conducting its business, free and clear of any liens, claims, charges, pledges,
security interests, options to purchase, encumbrances or equitable interests of
any nature whatsoever except for (i) liens for current year taxes not yet due
and (ii) de minimus liens that do not materially detract from or materially
impair the value of the properties, assets or operations of Intek.

                           q. Condition of Property. All buildings, offices, and
other structures and all machinery, equipment, fixtures, vehicles, and other
tangible personal property owned, leased or used by Intek are and will be on the
Transfer Date in good operating condition and repair, reasonable wear and tear
excepted, and are reasonably adequate and sufficient for all operations
presently conducted by it. Intek has the right to use its properties for all
operations presently conducted by Intek and, to the Knowledge of PPD, the
present uses of its properties are in conformity in all material respects with
applicable zoning provisions and in compliance in all material respects with all
applicable laws, ordinances and regulations, including without limitation,
building codes except where the failure to be in conformity does not result in a
Material Adverse Effect on Intek.

                           u. Certain Employee Matters. Except as set forth on

                  4. Representations, Warranties and Covenants of the
Corporation. The Corporation represents and warrants to PPD and covenants with
PPD that as of the Transfer Date:

                           a. Organization and Standing of the Corporation. The
Corporation is duly organized and validly existing and has complied with all
requirements to continue its existence under the laws of the State of Delaware,
and has the corporate power and authority to own, lease and use its properties
and to transact its business where and as now conducted.

                           b. Execution and Delivery Authorized. The execution

contemplated by this Agreement have been duly authorized by the board of
directors of the Corporation.

                           c. Validity of Agreement. The execution and
performance of this Agreement and the actions provided for or contemplated
hereunder will not violate the provisions of any agreement, instrument or
obligation to which the Corporation is a party or by which it is bound. Assuming
due authorization, execution and delivery hereof by PPD, this Agreement
constitutes the valid and binding agreement of the Corporation, enforceable
against the Corporation in accordance with its terms, subject as to
enforceability to general equitable principles and to the laws of bankruptcy,
insolvency or similar laws governing the rights of creditors.

                                       11
<PAGE>

                           d. Access and Information. The Corporation and its
representatives have been afforded full and free access to Intek's financial
statements and other information concerning Intek and the Corporation has been
afforded an opportunity to ask such questions of Intek's officers, employees,
agents, accountants and representatives concerning Intek's business, prospects,
operations, financial condition, assets, liabilities and other relevant matters,
including the rights, preferences and limitations of the Intek Shares, as the
Corporation deems necessary or desirable and has been given all such information
as has been requested, in order to evaluate the merits and risks associated with
holding the Intek Shares. The Corporation has conducted its own "due diligence"
investigation of Intek and its management and business, and its own analysis of
the merits and risks of holding the Intek Shares, and its own analysis of the
fairness and desirability of the terms governing the transfer of the Intek
Shares. The Corporation is familiar with the business conducted by Intek on and
has such knowledge and experience in financial and business matters that the
Corporation is capable of evaluating the merits and risks of the transfer of the
Intek Shares pursuant to the terms of this Agreement and of protecting the
Corporation's interests in connection therewith.

                           e. Investment Intent of the Corporation. The Intek
Shares are being acquired by the Corporation for its own account and not with a
view to, or for resale in connection with, any distribution or public offering
thereof within the meaning of the Securities Act of 1933, as amended (the
"Securities Act"). The Corporation understands that the Intek Shares have not
been, and will not be, registered under the Securities Act by reason of their
issuance in a transaction exempt from the registration requirements of the
Securities Act, that Intek has no present intention of registering the Intek
Shares, that the Intek Shares must be held by the Corporation indefinitely, and
that the Corporation must therefore bear the economic risk associated with
holding the Intek Shares indefinitely, unless a subsequent disposition thereof
is exempt from registration. The Corporation is able to bear the economic risk
of holding the Intek Shares pursuant to the terms of this Agreement. Each
certificate evidencing the Intek Shares shall be endorsed with the following
legend:

                  THE SHARES OF STOCK EVIDENCED BY THIS CERTIFICATE HAVE NOT
                  BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED
                  (THE "SECURITIES ACT"), OR ANY APPLICABLE STATE SECURITIES
                  LAWS, AND MAY NOT BE SOLD, OFFERED FOR SALE, ASSIGNED,
                  MORTGAGED, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED
                  WITHOUT AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
                  SECURITIES ACT COVERING SUCH SHARES, AND APPLICABLE STATE
                  SECURITIES LAW, OR AN OPINION OF COUNSEL REASONABLY
                  SATISFACTORY TO THE CORPORATION THAT THE TRANSACTION DOES NOT
                  VIOLATE FEDERAL OR STATE SECURITIES LAWS.

The Corporation acknowledges that no public market now exists for the Intek
Shares and that there can be no assurance that any public market will exist in
the future. The Corporation understands


                                       12
<PAGE>

that the Intek Shares will constitute "restricted securities", and under the
Securities Act and applicable regulations the Intek Shares may be resold without
registration under the Securities Act only in certain limited circumstances. In
this connection, the Corporation represents that it is familiar with Rule 144
under the Securities Act and understands the resale limitations imposed thereby
and the Securities Act.

                           f. Accredited Investor Status. The Corporation
represents and warrants that it is an "accredited investor" as defined in Rule
501 of Regulation D of the Securities Act.

                  5. Indemnification. Notwithstanding anything in this Agreement
to the contrary and subject to a time limit of eighteen (18) months following
the Transfer Date, PPD shall indemnify, defend, and hold harmless the
Corporation, its affiliates, successors and assigns from and against all General
Losses of the Corporation. Notwithstanding anything in this Agreement to the
contrary and subject to a time limit of eighteen (18) months following the
Transfer Date, the Corporation shall indemnify, defend, and hold harmless PPD,
its affiliates, successors and assigns from and against all General Losses of

set-off, counterclaim, or defense to payment that Borrower may have against the
beneficiary of any such Letter of Credit or Lender or any other Person,

<PAGE>

                  (a) Borrower hereby irrevocably instructs Lender to pay any
draft complying with the terms of any Letter of Credit. Borrower assumes all
risks of the acts and omissions of the beneficiary and other users of any Letter
of Credit.

                  (b) Lender and its branches, affiliates and/or correspondents
shall not be responsible for and Borrower shall indemnify and hold Lender and
its branches, affiliates and correspondents harmless from and against all
liability, loss and expense (including reasonable attorney's fees and costs)
incurred by Lender or its branches, affiliates or correspondents relative to or
as a consequence of (i) any failure of Borrower to perform the agreements
hereunder and under any Letter of Credit Application, (ii) any Letter of Credit
Application, this Agreement, any Letter of Credit and any drafts and acceptances
under or purporting to be under any Letter of Credit, (iii) any action taken or
omitted by Lender or its branches, affiliates or correspondents at the request
of the Revolving Credit Loan Borrower Group, (iv) any failure or inability to
perform in accordance with the terms of any Letter of Credit by reason of any
control or restriction rightfully or wrongfully exercised by any de facto or de
jure government, group or individual asserting or exercising governmental
powers, and (v) any consequences arising from causes beyond the control of
Lender or its branches, affiliates or correspondents.

                  (c) Except for gross negligence and willful misconduct of
Lender, and its branches, affiliates and correspondents, Lender and its
branches, affiliates and correspondents, shall not be liable or responsible in
any respect for any (i) error, omission, interruption or delay in transmission,
dispatch or delivery of any one or more messages or advices in connection with
any Letter of Credit, whether transmitted by cable, telegraph, mail or otherwise
and despite any cipher or code which may be employed, or (ii) action, inaction
or omission which may be taken or suffered by it or them in good faith or
through inadvertence in identifying or failing to identify any beneficiary or
otherwise in connection with any Letter of Credit.

                  (d) Any Letter of Credit may be amended, modified or revoked
only upon the receipt by Lender from Borrower and the beneficiary (including any
transferees and assignees of the original beneficiary), of a written consent and
request for such amendment, modification or revocation, and then only on such
terms and conditions as Lender may prescribe in Lender's discretion.

                  (e) If any Laws, orders of court and/or rulings or regulations
of any governmental authorities of the United States, any state, or foreign
government permits the beneficiary under a Letter of Credit to require Lender or
its branches, affiliates or correspondents to pay drafts under or purporting to
be under a Letter of Credit after the expiration date of the Letter of Credit,
Borrower shall reimburse Lender for any such payment pursuant to Section 2C.05.

                  (f) Except as may otherwise be specifically provided in a
Letter of Credit or Letter of Credit Application, the laws of the Commonwealth
of Virginia and the Uniform Customs and Practice for Documentary Credits, 1993
Revision, International Chamber of Commerce Publication No. 500 shall govern the
Letters of Credit. In the event of a conflict


                                      -28-
<PAGE>

between the Uniform Customs and Practice for Documentary Credits and the laws of
the Commonwealth of Virginia, the Uniform Customs and Practice for Documentary
Credits shall prevail.

         SECTION 2C.07. USE OF LETTERS OF CREDIT. Each Letter of Credit shall be
used solely for a general corporate purposes of the US Corporation. In addition,
the US Corporation may have Letters of Credit issued on behalf of the UK
Corporations in other than U.S. Dollars.

         SECTION 2C.08 LETTERS OF CREDIT DENOMINATED IN OTHER THAN U.S. DOLLARS.
For purposes of determining the outstanding balance of Letters of Credit, the
aggregate principal amount of Letters of Credit issued and outstanding in other
than U.S. Dollars shall be converted to the U.S. Dollar equivalent amount, as
calculated by Lender in Lender's reasonable discretion, on the date of such
determination.


                                  ARTICLE II-D
                   CREDIT FACILITY - GENERAL CREDIT PROVISIONS

         SECTION 2D.01. LENDER RECORDS. Absent manifest error, Lender's records
of Loans made and payments received in respect of Loans, including Lender's
entries on any Revolving Credit Notes or schedules that may be attached to
Revolving Credit Notes from time to time, and of Letters of Credit, and all
amounts drawn thereunder and all reimbursements thereof, shall be presumed
correct. Notwithstanding the foregoing, the absence of a Revolving Credit Note
or Lender's failure to record loan amounts or payments or other related
information (or any error in recording such amounts or other information) shall
not limit or affect any Borrower's agreement and obligation to repay the Loans,
and all accrued interest and other amounts on the Loans, in accordance with the
terms of this Agreement, the Notes, and the other Credit Documents.

         SECTION 2D.02. COMPUTATION OF INTEREST. All interest shall accrue based
on a 360-day year for the actual number of days outstanding.

         SECTION 2D.03. LATE CHARGES; DEFAULT INTEREST. If any payment of
principal or interest due on either of the Loans, or any payment under any
reimbursement obligation in respect of any Letter of Credit, is not paid to
Lender within ten (10) days after the date that such payment is due, then
Lender, in Lender's sole discretion, shall be entitled to impose on Borrower a
"late charge" equal to five percent (5%) of the amount not paid when due, and
Borrower and the Guarantors shall be obligated to pay each such late charge to
Lender immediately upon the imposition thereof by Lender. In Lender's
discretion, upon and after the occurrence of an Event of Default, interest on
the outstanding principal balances of all Loans shall accrue and be payable at
the Default Rate.

         SECTION 2D.04. Omitted.

                                      -29-
<PAGE>

         SECTION 2D.05. UNUSED CREDIT FEE. Borrower shall pay to Bank the Unused
Credit Fee for each year or portion thereof prior to the termination of Bank's
obligations to extend Revolving Credit under this Agreement. The accrued portion
of the Unused Credit Fee shall be due and payable to Bank in arrears on each
Quarterly Payment Date. Borrower hereby authorizes Bank to debit Borrower's
account maintained with Bank to pay the Unused Credit Fee on each Quarterly
Payment Date. For purposes of the calculation of the Unused Credit Fee, the
unused portion of the Revolving Credit shall be the average daily Available
Revolving Credit Amount during the applicable quarter. The Unused Credit Fee
shall be based upon the Consolidated Funded Debt to EBITDA ratio for the
preceding fiscal quarter for which Bank shall have received quarterly financial
statements pursuant to this Agreement, E.G. the Unused Credit Fee for the period
from January through March of a particular year shall be based upon the
quarterly financial statements for the fiscal quarter ending the immediately
preceding December.

         SECTION 2D.06. MANDATORY ADDITIONAL PAYMENTS. At any time that the
aggregate outstanding principal balance of Revolving Credit Loans, plus the
aggregate face amounts of outstanding Letters of Credit, exceeds the Revolving
Credit Committed Amount, Borrower shall immediately and without demand, and
without set-off, defense or counterclaim of any kind, make payments to Lender of
Revolving Credit Loans in the amount necessary in order to reduce the aggregate
outstanding balance of Revolving Credit Loans so that the aggregate outstanding
balance of Revolving Credit Loans, plus the aggregate face amounts of
outstanding Letters of Credit, will not exceed the Revolving Credit Committed
Amount.

         SECTION 2D.07. PREPAYMENTS. Borrower may prepay Revolving Credit Loans,
the Term Loan and the Acquisition Loan in whole or in part at any time without
premium or penalty. All prepayments of the Term Loan or the Acquisition Loan
shall be applied in inverse order of the maturity of the scheduled payments. Any
prepayment of the Loans shall not affect Borrower's obligation to continue to
make payments under and in accordance with any swap agreement (as defined in 11
U.S.C. ss.101), which payments shall be governed exclusively by the term of such
swap agreement.

         SECTION 2D.08. MANNER OF PAYMENTS. All payments to be made to Lender
shall be made in Dollars in immediately available funds without set-off,
defense, counterclaim or deduction of any kind, not later than 12:00 noon,
Eastern Time, at the Payment Office on the dates specified for such payments
under this Agreement, the Revolving Credit Notes, the Term Note, the Seller Note
or the other Credit Documents. Borrower's failure to make any such payments by
12:00 noon, Eastern Time, on the dates on which such payments are due shall not
be an Event of Default so long as such payments are made later on the day that
such payments are due provided that any such payments made after 12:00 noon,
Eastern Time, on the dates such payment are due shall be deemed to have been
made on the next Business Day thereafter for purposes of calculating interest on
amounts outstanding under the Loans. Payments made in other than Dollars shall
be accepted subject to collection.

         SECTION 2D.09. APPLICATION OF PAYMENTS. Payments made by Borrower to
Lender shall be applied in such order as Lender may determine in Lender's
discretion.

                                      -30-
<PAGE>

         SECTION 2D.10. CAPITAL ADEQUACY. Borrower shall pay to Lender from time
to time upon Lender's demand such additional amounts as Lender may determine in
Lender's discretion to be necessary to compensate Lender for any reduction in
the rate of return on Lender's capital (or on the capital of Lender's holding
company, if any) due to the applicability of any Capital Adequacy Requirement,
as a consequence of the existence of Lender's obligations under this Agreement,
to a level below, by an amount reasonably deemed by Lender to be material, that
which Lender (or Lender's holding company) could have achieved but for such
Capital Adequacy Requirement.

         SECTION 2D.11. RATE ADEQUACY. If Lender reasonably determines in
Lender's reasonable discretion that (a) deposits in Dollars (in the applicable
amounts) or quotations of interest rates for the relevant deposits are not being
offered to Lender in the relevant amounts or for the relevant maturities for
purposes of determining the rates of interest on LIBOR Rate Loans under this
Agreement, or (b) the applicable LIBOR Rate will not adequately and fairly
reflect Lender's cost of funding LIBOR Rate Loans for such Interest Periods,
then any obligation to make such LIBOR Rate Loans under this Agreement shall be
suspended until such time as the inadequacy or unavailability of LIBOR Rate
Loans no longer exists. In the event LIBOR Rate Loans are not available on
account of operation of this Section, Lender shall use the Prime Rate as an
alternate index or reference rate.

         SECTION 2D.12. REGULATORY CHANGE. Borrower shall pay to Lender from
time to time, upon Lender's demand, such additional amounts as Lender may
determine in Lender's reasonable discretion to be necessary to compensate Lender
for any Additional LIBOR Costs resulting from any Regulatory Change that: (a)
subjects Lender to any tax, duty or other charge in respect of the LIBOR Rate
Loans (or the Notes evidencing LIBOR Rate Loans) or subjects the Lender to
changes in the basis of taxation of any amounts payable to Lender under this
Agreement (or the Notes) in respect of any LIBOR Rate Loans or Lender's
obligations to make LIBOR Rate Loans (excluding changes in the rate of tax on
the overall net income of Lender by the jurisdiction in which Lender has its
principal office); or (b) imposes, modifies, or deems applicable any reserve,
special deposit or similar requirements (other than the LIBOR Reserve
Requirements used in the calculation of the LIBOR Rate under this Agreement)
relating to any extensions of credit or against assets of, or any deposits with,
or other liabilities of, Lender (including any LIBOR Rate Loans or any deposits
referred to in the definition of LIBOR Base Rate in this Agreement), or Lender's
commitment to make LIBOR Rate Loans under this Agreement; or (c) imposes any
other condition affecting this Agreement or the Notes (or any of such extensions
or credit or liabilities) or Lender's commitment to make LIBOR Rate Loans under
this Agreement. Additionally, if any Regulatory Change or any event affecting
the United States money markets or the London interLender market, causes Lender
to either (X) incur Additional LIBOR Costs based on or measured by the excess
above a specified level of the amount of a category of deposits or other
liabilities of Lender that includes deposits by reference to which the interest
rate on LIBOR Rate Loans is determined as provided in this Agreement or a
category of extensions of credit or other assets of Lender that includes LIBOR
Rate Loans, or (Y) become subject to restrictions on the amount of such category
of liabilities or assets that it may hold, then, if Lender


                                      -31-
<PAGE>

so elects, the obligation of Lender to make or renew LIBOR Rate Loans under this
Agreement shall be suspended until such Regulatory Change ceases to be in effect
or the effects of such other event cease.

         SECTION 2D.13. DESIGNATION OF AGENT AND ATTORNEY-IN-FACT. Each Borrower
that is a party to any Credit Document hereby irrevocably appoints EHI (referred
to herein as the "BORROWER GROUP AGENT") as the agent and attorney-in-fact for
such Borrower with full power and authority to act on behalf of such Borrower in
all respects with respect to any actions, waivers, consents, payments, receipts,
or notices, whether or not required under this Agreement or the other Credit
Documents, or as the Borrower Group Agent may engage in, provide, give or take
in its sole and unfettered discretion. Each such Borrower agrees that all
actions taken, waivers or consents provided, payments made or received, or
notices given or received, by Lender, in each case by or to the Borrower Group
Agent, shall be effective as to such Borrower regardless of whether such action,
waiver, consent or notice was taken or approved by, or given or received by, any
Person other than the Borrower Group Agent. In all respects and circumstances,
Lender is entitled to rely without limitation on any and all actions, waivers,
consents, and notices of the Borrower Group Agent as actions, waivers, consents
or notices of all such Borrowers, including any and all agreements to modify or
amend in any respect, or grant any waiver or consent under, or to give or
receive any notice with respect to, this Agreement or any other Credit
Documents, and Lender is under no expectation or obligation whatsoever to
inquire as to whether any such action or waiver was approved or ratified by, or
notice given or received by, any such Borrower, and may act as if any such
action, waiver, consent, or notice was engaged in, provided, taken, given or
received by each such Borrower. In this respect, absent written notice to the
contrary with respect to a specified matter, it is agreed that, in each and
every circumstance insofar as Lender is concerned, any action taken, waiver or
consent given, or notice given or received by the Borrower Group Agent, shall be
deemed taken, given or received by each such Borrower even absent an express
indication that such action is taken, such waiver or consent is given, or such
notice is given or received by any such Borrower.

         SECTION 2D.14. NET PAYMENTS. Any and all payments of principal,
interest, fees and other Obligations by Borrower hereunder and under the Notes
and the other Credit Documents shall be made free and clear of and without
deduction for any and all Taxes. As used herein, "TAXES" means (a) All present
or future taxes, levies, imposts, deductions, charges or withholding, and all
liabilities, imposed by any taxing authority in any jurisdiction (other than the
United States, except as otherwise provided in clause (b) of this sentence) by
reason of the payment of principal, interest, fees and other Obligations
hereunder, and (b) shall also include taxes imposed by any United States taxing
authority by reason of the payment of increased amounts pursuant to clause (i)
of the next sentence, but only to the extent attributable to such increase. If
any such Taxes shall be required by law to be deducted from or in respect of any
principal, interest, fees or other Obligations payable to Lender hereunder: (i)
the sum payable by Borrower shall be increased as necessary so that after taking
all such Taxes into account, Lender shall receive an amount equal to the sum it
would have received had no such deductions been made; (ii) the applicable
Borrower Group shall make all required deductions for such


                                      -32-
<PAGE>

Taxes; and (iii) the applicable Borrower Group shall pay the full amount
deducted to the relevant taxing authority in accordance with applicable law and
shall furnish Lender with proof of such payment. The term "Taxes" shall not
include any taxes imposed on the income of the Lender.

         SECTION 3.25. ERISA STATUS.

                  (a) Schedule 3.25 is a true, accurate, and complete listing of
each Plan. Each Plan is in compliance in all material aspects with the
applicable provisions of ERISA and the Code. Except as otherwise expressly
indicated on Schedule 3.25, each Qualified Plan and each Multiemployer Plan has
been determined by the Internal Revenue Service to qualify under Section 401 of
the Code, and the trusts created thereunder have been determined to be exempt
from tax under Section 501 of the Code, and nothing has occurred that would
cause the loss of such qualification or tax-exempt status. There are no
outstanding liabilities under Title IV of ERISA with respect to any Plan which
could reasonably be expected to have a Material Adverse Effect. No Plan subject
to Title IV of ERISA has any Unfunded Benefit Liability which could reasonably
be expected to have a Material Adverse Effect. Neither Borrower nor any ERISA
Affiliate has transferred any Unfunded Benefit Liability to a person other than
an ERISA Affiliate or has otherwise engaged in a transaction that could be
subject to Section 4069 or 4212(c) of ERISA which could reasonably be expected
to have a Material Adverse Effect. Neither any Borrower nor any ERISA Affiliate
has incurred nor reasonably expects to incur (x) any liability (and no event has
occurred which, with the giving of notice under Section 4219 of ERISA, would
result in such liability) under Sections 4201 or 4243 of ERISA with respect to a
Multiemployer Plan, or (y) any liability under Title IV of ERISA (other than
premiums due but not delinquent under Section 4007 of ERISA) with respect to a
Plan, which could, in either event, reasonably be expected to have a Material
Adverse Effect. No application for a funding waiver or an extension of any
amortization period pursuant to Section 412 of the Code has been made with
respect to any Plan (other than a Multiemployer Plan). No ERISA Event has
occurred or is reasonably expected to occur with respect to any Plan which could
reasonably be expected to have a Material Adverse Effect. Each Borrower and each
ERISA Affiliate has complied in all material respects with the notice and
continuation coverage requirements of Section 4980B of the Code. Neither any
Borrower nor any ERISA Affiliate has any contingent liability for
post-retirement benefits under a welfare plan (as defined in Section 3(1) of
ERISA), other than liability for continuation of coverage described in Section
4980B of the Code, except as disclosed on the financial statements of each
Borrower prepared in accordance with GAAP applied on a consistent basis and
delivered to Lender.

                  (b) In respect of the UK Corporations, Schedule 3.25A contains
a true, accurate and complete listing of all agreements or arrangements for the
provision of pensions, allowances, lump sums or other similar benefits on
retirement, death or long term ill health for the benefit of any current or
former employee of either UK Corporation or their dependents, including ex
gratia arrangements (each a "UK PLAN"). To the best knowledge of Obligors:

                           (i) Full and accurate particulars of each UK Plan
have been disclosed including, without limitation, copies of the current trust
deed and rules plus any amending deeds or resolutions, members' booklets plus
any subsequent announcements to members, membership details, details of
contributions payable by and in respect of members, most recent actuarial report
and valuation, most recent scheme accounts, evidence of Inland Revenue approval
and contracting-out status and evidence of compliance with the Pensions Act 1995
and regulations.

                                      -42-
<PAGE>

                           (ii) Other than as disclosed there are no other
Pension Schemes for current or past directors or employees of the Company.

                           (iii) In relation to each UK Plan within the three
years ending on the date of this agreement no power to augment benefits has been
exercised, no discretion has been exercised to admit an employee to membership
of the pension scheme who would not otherwise be eligible and no discretion has
been exercised to provide a benefit which would not otherwise be provided; all
benefits (other than a refund of contributions with interest where appropriate)
payable under each UK Plan on the death of a member while in an employment to
which the pension scheme relates are fully insured by a policy with an insurance
company of good repute; there are no contributions to a UK Plan which are due
but unpaid and have remained unpaid for more than one month and in any event
contributions have been paid which are at least equal to and by the due date
specified in any schedule of contributions or payments applicable under Section
58 or 87 of the Pensions Act 1995; no takeover protection provision will be
triggered by Completion; each UK Plan is sufficiently funded on an ongoing basis
using the assumptions used in the last actuarial valuation to secure at least
the benefits accrued to Completion (other than those which are insured) and in
addition is sufficiently funded to meet the minimum funding requirement as
defined in Section 56 of the Pensions Act 1995, and all information provided to
the Pension Scheme actuary for the purposes of the last actuarial valuation was
true, accurate and complete in all respects and there have been no events since
the date of that valuation which would show a deterioration of the funding
position of a UK Plan were such a valuation to be undertaken at the date of
Completion.

                           (iv) Each UK Plan is either approved by the Board of
Inland Revenue for the purposes of Chapter I Part XIV of the Income and
Corporation Taxes Act 1988 or is a scheme under which the benefits provided or
to be provided are consistent with the approval of the scheme by the Board of
Inland Revenue for such purposes and is a scheme in respect of which an
application for such approval has been made and has not been withdrawn or
refused and the Board of Inland Revenue have not given notice to the applicant
that they believe the application has been dropped; is established under
irrevocable trusts; has been administered in accordance with all applicable laws
(including Article 119 of the Treaty of Rome), regulations and requirements of
any competent governmental body or regulatory authority and the trusts and rules
of the UK Plan; has not been the subject of any report of wrongdoing or
irregularities to the Occupational Pensions Regulatory Authority nor are there
any circumstances which would justify such a report; is a scheme in respect of
which all actuarial, consultancy, legal and other fees, charges or expenses have
been paid and for which no services have been provided for which an account or
invoice has not been rendered; and has no investment in employer-related assets
as defined in Section 40 of the Pensions Act 1995.

                           (v) No claim has been threatened or made or
litigation commenced against the trustees or administrators of any UK Plan or
against UK Corporations or any other person whom either UK Corporation is or may
be liable to indemnify or compensate in respect of any matter arising out of or
in connection with any UK Plan. There are no circumstances which


                                      -43-
<PAGE>

may give rise to any such claim or litigation. There are no unresolved disputes
under any UK Plan's internal dispute resolution procedure.

         SECTION 3.26. ENVIRONMENTAL STATUS. Except as set forth in Schedule
3.26:

                  (a) Each Borrower has obtained and maintained all
Environmental Permits necessary to conduct its business, both as done currently
and as proposed except insofar as collectively any non-compliance would not have
a Material Adverse Effect..

                  (b) Each Borrower has complied with all Environmental Laws
(including Environmental Permits) except insofar as collectively any
non-compliance would not have a Material Adverse Effect.

                  (c) To the knowledge of each Borrower, neither any Borrower

released, emitted, buried, leaked, or disposed of Regulated Substances on any
Property ever owned, leased or operated by any of them.

                  (d) To the best knowledge of each Borrower, no one else,

or leased by any Borrower or any Environmental Affiliate known to it.

Borrower shall give Lender written notice of each Notification Event, which

Event, and (iii) a description of the manner in which any Borrower has addressed
or otherwise responded to the Notification Event or intends to address or

         SECTION 4.03. EXISTENCE. Each Borrower shall maintain its corporate or
other legal existence, in each jurisdiction in which it is incorporated or
otherwise formed, and in each jurisdiction where it is required to register or
qualify to do business except for failures to register or qualify which,
individually or in the aggregate, would not have a Material Adverse Effect.

         SECTION 4.04. PLACES OF BUSINESS. Borrower shall give Lender at least
thirty (30) days' prior written notice of the intended opening of any new
location in addition to the Designated Locations. Prior to such opening, such

executed and delivered, to Lender such agreements, documents, and instruments as
Lender may deem necessary or desirable in Lender's discretion to protect

types of coverage are required by the terms of the other Credit Documents,
provided that the insurance coverages maintained by each Borrower shall at all
times be at least comparable in amount and in all other material respects, as
the coverages described on Schedule 3.16. Each Borrower shall provide to Lender
promptly upon Lender's request from time to time certificates, policies or
endorsements as Lender shall require as proof of such insurance, and if any
Borrower fails to do so, Lender is authorized, but not required, to obtain such
insurance at the expense of the Obligors. All insurance policies shall provide
for at least thirty (30) days' prior written notice to Lender of any
cancellation or reduction in coverage and Lender may act as attorney-in-fact for
any Borrower in obtaining, and at any time an Event of Default exists,
adjusting, settling, amending and canceling such insurance. Each Borrower shall
cause Lender to be named as a loss payee and an additional insured (but without
any liability for any premiums) under all such insurance policies as to which
such is obtainable at no or reasonable cost and shall cause each Borrower to
obtain non-contributory Lender's loss payable endorsements to all such insurance
policies in form and substance satisfactory to Lender. Such Lender's loss
payable endorsements shall specify that the proceeds of such insurance shall be
payable to Lender as its interests may appear and further specify that Lender
shall be paid regardless of any act or omission by any Borrower or any other
Person. To the extent Borrower defaults in regularly scheduled payments on the
Notes or other Credit Documents, all proceeds of such casualty insurance and
business interruption insurance not applied to repair and replacement of the
Property shall be paid to Lender for application to the Obligations in
accordance with the terms of this Agreement and the other Credit Documents or
otherwise. Lender shall not be responsible for any failure to collect any
insurance proceeds due under the terms of any policy regardless of the cause of
such failure.

         SECTION 4.07. TAXES. Each Borrower shall pay and discharge, or cause to
be paid and discharged, promptly all taxes, assessments, and governmental
charges or levies imposed upon any Borrower or upon any Borrower's income and
profits, or upon any of its Property or any part thereof, before the same shall
become in default, as well as all lawful claims for labor, materials and
supplies or otherwise which, if unpaid, might become a Lien upon such Property
or any part thereof; PROVIDED, HOWEVER, THAT no Borrower shall be required to
pay and discharge or to cause to be paid and discharged any such tax,
assessment, charge, levy or claim so long as the validity thereof shall be
contested in good faith by appropriate proceedings and such Borrower shall have
set aside on its books adequate reserves with respect to any such tax,
assessment, charge, levy or claim, so contested.

any claim by any Person not contracted with by Lender for a commission or
finder's fee or other compensation of any kind attributable to any extensions of
credit or other matters or transactions contemplated under this Agreement and
the other Credit Documents, and shall pay Lender's attorney's fees, litigation
expenses and court costs in defending any such claims.

          SECTION 4.13. REVIEW AND AUDIT. Each Borrower shall maintain its
financial books and records in accordance with GAAP. Lender shall be permitted
access to all Records at any location, including any Designated Location during
normal business hours on reasonable notice and shall be permitted to take
copies, at Borrower's expense, of such Records as Lender may request. Each
Borrower shall permit and authorize Lender through any Person designated by
Lender ("LENDER'S DESIGNEE"), at such times and as often as Lender may
reasonably request, to visit, inspect, examine, audit and verify any of the
properties and Records of each Borrower relevant to the subject matter of this
Agreement or any other Credit Documents or any Obligor Information or the
financial condition of each Borrower. The actions of Lender and Lender's
Designee pursuant to this Section shall be scheduled and conducted so as not to
be unreasonably disruptive to Borrower's operations.

         SECTION 4.14. RATE HEDGING. Upon the request of Lender, Borrower shall

expense of the Term Loan, all upon terms and subject to such conditions as shall
be acceptable to Lender (or if such transaction is with another financial
institution, all upon terms and subject to conditions as shall be approved by
Lender in writing).

promptly provide written notice thereof to Lender and, upon written request of
Lender, shall provide Lender with such reports, certificates, engineering

                  (n) All of each Borrower's books, records, documents, ledger
cards, invoices, bills of lading and other shipping evidence, credit files,
computer programs, tapes, discs, diskettes, and other data and software storage
medium and devices, customer lists, mailing lists, mailing labels, business
forms and stationery, and other property and general intangibles evidencing or
relating to each Borrower's Accounts, Inventory and/or other Collateral, or any
Account Debtor, (including any rights of any Borrower with respect to the
foregoing maintained with or by any other person) ("RECORDS").

         SECTION 4A.02. CHATTEL PAPER AND INSTRUMENTS. Each Borrower shall mark
or stamp the first page and the signature page of all Chattel Paper with a
legend clearly and conspicuously stating that such Chattel Paper is subject to a
continuing security interest in favor of Lender, and promptly upon Lender's
request from time to time, and at each Borrower's sole cost and expense, and
without limiting the effect of any other provision of this Agreement or any
other Credit Document, each Borrower shall: (i) deliver to Lender such Chattel
Paper, and execute and deliver to Lender such assignments of Chattel Paper and
related endorsements of Chattel Paper,


                                      -56-
<PAGE>

as Lender may request, and shall cause the makers of the Chattel Paper to
deliver to Lender such acknowledgments of the assignments of Chattel Paper as
Lender may request; and (ii) deliver to Lender such Instruments, and execute and
deliver to Lender such collateral assignments of Instruments and related
endorsements of Instruments, as Lender may request, and shall cause the makers
of the Instruments to deliver to Lender such acknowledgments of assignment of
Instruments as Lender may request.

         SECTION 4A.03. BORROWER'S COLLECTION PRIVILEGES. To further secure the
Obligations, and in addition to Lender's other rights, powers, and remedies
under this Agreement, including those under Section 7.09, each Borrower agrees
that Lender shall have the exclusive right to collect from Account Debtors, in
the name of such Borrower or Lender, or in the name of Lender's designee, all
Accounts, Chattel Paper, Documents, General Intangibles, Instruments, Investment
Property and similar Collateral; PROVIDED, HOWEVER, THAT prior to the revocation
of the privilege by Lender in writing in Lender's discretion at any time after
the occurrence of a Default, each Borrower shall be privileged to collect such
Borrower's Accounts, Chattel Paper, Documents, General Intangibles, Instruments,
Investment Property and similar Collateral in the ordinary course of such
Borrower's business so long as such Borrower shall apply all proceeds of such
Collateral and collections in accordance with the terms of this Agreement.
Nothing in this Agreement shall be construed as obligating Lender to take any
actions to collect any Collateral.

         SECTION 4A.04. COLLATERAL ACCOUNT. Following the occurrence of an Event
of Default and requirement by Lender that any Borrower maintain a Lock-Box, each
Borrower shall maintain a Collateral Account into which Items of Payment
received and processed through the Lock-Box, and any other payments received by
such Borrower from Account Debtors, shall be deposited on the date of such
Borrower's receipt thereof.

         SECTION 4A.05. LOCK-BOX. Following the occurrence of an Event of
Default and notice from Lender that a Lock-Box shall be required, each Borrower
shall maintain a Lock-Box administered by Lender in accordance with Lender's
standard Lock-Box service and shall direct each Account Debtor to make payments
on Accounts to the Lock-Box address.

         SECTION 4A.06 ADDITIONAL COLLATERAL. If any Borrower proposes to
acquire additional Property which would constitute Collateral, and if the
security interest of Lender would not be a first priority perfected security
interest upon acquisition of such Property, then except with respect to
Permitted Liens, as to which this Section shall not apply, such Borrower shall,
before acquiring such Property, take whatever actions Lender may require in
order that, upon the acquisition of such Property, Lender will have a first
priority perfected security interest therein.

         SECTION 4A.07 FURTHER ASSURANCES OF COLLATERAL. Each Borrower shall
execute such further agreements, documents, financing statements and other
instruments as may reasonably be requested by Lender in order to perfect the
security interests granted herein. To the extent that possession of the
Collateral may be necessary or advisable to perfect the collateral assignment
and security interests granted hereby, each Borrower shall deliver such
Collateral to Lender upon the request of Lender; PROVIDED THAT before the
occurrence of an Event of Default, Lender shall


                                      -57-
<PAGE>

not require physical possession of Collateral if such possession would
materially impair Borrowers' ability to transact business in a commercially
reasonably manner. Without limiting the generality of the foregoing, each
Borrower hereby covenants and agrees that all Liens granted to Lender under this
Agreement and/or any other Credit Documents, are, and shall at all times be,
first priority Liens, subject only to Permitted Liens, and that no Property of
any Borrower shall be subject to any Lien (regardless of priority) except for
Permitted Liens.

                  (i) If any statement, report, certificate, opinion, or other
information furnished to Lender with or in accordance with the terms of this
Agreement (including all annexes, schedules, and exhibits to the Credit

                  (j) The determination in good faith by Lender that a material

business prospects of such Obligor as heretofore most recently disclosed to
Lender in writing by such Obligor, or the occurrence of any other fact, event or
circumstance which Lender reasonably believes is likely to have a Material
Adverse Effect on the Obligors on a consolidated basis; or

                  (k) If one or more judgments or decrees shall be entered

                                      -62-
<PAGE>

         SECTION 6.02. ACCELERATION. Upon the occurrence of an Event of Default,
and at any time thereafter unless and until such Event of Default has been
waived by Lender in writing or cured to the satisfaction of Lender as expressly
acknowledged by Lender in writing, Lender may take any or all of the following
actions against any or all Obligors: (a) declare the Credit Termination Date
accelerated (without the necessity of any notice) on any Loan; and/or (b)
declare the unpaid principal of, and all accrued and unpaid interest on, the
Loan and any and all other outstanding and unpaid Obligations to be due,
whereupon the same shall be immediately due and payable without presentment,
demand, protest or other notice of any kind, all of which are hereby waived by
each Borrower and each other Obligor; and/or (c) enforce any and all rights and
interests created and existing under the Credit Documents and all rights of
set-off; provided, however, without limiting the generality of the foregoing,
upon the occurrence of an Event of Default described in Section 6.01(n) above,
(i) the Credit Termination Date shall be immediately accelerated (without the
necessity of any notice), and (ii) the unpaid principal of, and all accrued and
unpaid interest on, the Loan and any and all other outstanding and unpaid
Obligations shall be immediately due and payable to Lender without any action on
the part of Lender, and without presentment, demand, protest, or other notice of
any kind, all of which are hereby waived.

         SECTION 6.03. OTHER REMEDIES. In addition to the foregoing, upon the
occurrence of an Event of Default, Lender may do any of the following:

                  (a) Collect and enforce payment of all of each Borrower's
Deposit Accounts, Accounts, General Intangibles, Chattel Paper, Instruments and
Documents and rights and remedies with respect to such Property as would
otherwise be exercised by any Borrower, including: the power to take possession
of and endorse in the name of such Borrower, any Items of Payment of any kind
and any other documents received; the power to extend the time of payment of,
the time to sue for, and the time to give acquittances for, monies due; and the
power to withdraw proceeds deposited in the name of the applicable Borrower in
any Lender or savings institution.

                  (b) Sell or otherwise dispose of the Collateral, or any part
thereof, at public or private sale (or at any broker's board or on any
securities exchange) or otherwise, for cash, upon credit or for future delivery
as Lender shall deem appropriate. Each such purchaser at any such sale shall
hold the property sold absolutely, free from any claim or right on the part of
any Borrower, and each Borrower hereby waives (to the extent permitted by law)
all rights of redemption, stay and appraisal which any Borrower now has or may
at any time in the future have under any rule of law or statute now existing or
hereafter enacted. Lender shall give each Borrower at least ten (10) days'
written notice (which each Borrower agrees is reasonable notice within the
meaning of Section 9-504(3) of the UCC) of Lender's intention to make any sale
of Collateral owned by any Borrower. Such notice, in the case of a public sale,
shall state the time and place for such sale and, in the case of a sale at a
broker's board or on a securities exchange, shall state the board or exchange at
which such sale is to be made and the day on which the Collateral, or portion
thereof, will first be offered for sale at such board or exchange. Any such


                                      -63-
<PAGE>

public sale shall be held at such time or times within ordinary business hours
and at such place or places as Lender may fix and state in the notice of such
sale, and at any such sale, the Collateral, or portion thereof, to be sold may
be sold in one lot as an entirety or in separate parcels, as Lender may (in its
discretion) determine, and Lender shall not be obligated to make any sale of any
Collateral if Lender shall determine not to do so, regardless of the fact that
notice of sale of such Collateral shall have been given, and Lender may, without
notice or publication, adjourn any public or private sale or cause the same to
be adjourned from time to time by announcement at the time and place fixed for
sale, and such sale may, without further notice, to any Borrower or anyone else,
be made at the time and place to which the same was so adjourned. In case any
sale of all or any part of the Collateral is made on credit or for future
delivery, the Collateral so sold may be retained by Lender until the sale price
is paid by the purchaser or purchasers thereof, but Lender shall not incur any
liability in case any such purchaser or purchasers shall fail to take up and pay
for Collateral so sold and, in case of any such failure, such of the Collateral
may be sold again upon notice to Borrower as set forth in this Section. At any
public sale made pursuant to this Section, Lender may bid for or purchase, free
(to the extent permitted by law) from any right of redemption, stay or appraisal
on the part of Borrower (all said rights being also hereby waived and released
to the extent permitted by law), the Collateral or any part thereof offered for
sale and may make payment on account thereof by using any claim then due and
payable to Lender from Borrower as a credit against the purchase price, and
Lender may, upon compliance with the terms of sale, hold, retain and dispose of
such property without further accountability to any Borrower therefor. For
purposes hereof, a written agreement to purchase the Collateral or any portion
thereof shall be treated as a sale thereof; Lender shall be free to carry out
such sale pursuant to such agreement, and Borrower shall not be entitled to the
return of the Collateral or any portion thereof subject thereto, notwithstanding
the fact that after Lender shall have entered into such an agreement, all Events
of Default shall have been remedied and the Obligations paid in full. As an
alternative to exercising the power of sale herein conferred upon Lender, Lender
may proceed by a suit or suits at law or in equity to foreclose this Agreement
and to sell the Collateral or any portion thereof pursuant to a judgment or
decree of a court or courts having competent jurisdiction or pursuant to a
proceeding by a court-appointed Receiver. Upon any sale of Collateral by Lender
(including a sale pursuant to a power of sale granted by statute or under a
judicial proceeding), the receipt of Lender or of the officer making the sale
shall be a sufficient discharge to the purchaser or purchasers of the Collateral
being sold, and such purchaser or purchasers shall not be obligated to see to
the application of any part of the purchase money paid over to Lender or such
officer or be answerable in any way for the misapplication thereof. Borrower
agrees that in selling or otherwise disposing of the Collateral and in
exercising Lender's rights and remedies to the Collateral, Lender and/or any
Receiver and/or any designee of Lender and/or any Receiver shall have the
unrestricted and irrevocable right (so long as not violative of law) to
advertise, sell, lease, license or otherwise dispose of the Collateral under and
together with, and shall otherwise have the unrestricted and irrevocable right
to use, without limitation, in connection therewith, any and all of Borrower's
advertisements in any medium (and other marketing and promotional materials in
any medium), brochures, signs, stationery, business forms, packaging and
shipping materials, programs, software, licenses, permits, consents, approvals,
and Intellectual Property relating to such Collateral and/or Borrower's
business, and

                                      -64-
<PAGE>


all agreements with employees and former employees relating to any of the
foregoing, and each Borrower shall indemnify and hold harmless Lender and any
Receiver, and their designees, shareholders, directors, officers, employees,
agents, attorneys, accountants, and other advisors, from and against any and all
claims (including claims for royalties and/or money damages and/or claims for
injunctive relief), liabilities, damages, royalties, and penalties of any
Person, and Lender's and any Receiver's costs and expenses (including attorney's
fees) and those of their designees, shareholders, directors, officers,
employees, agents, attorneys, accountants, and other advisors, incurred to
defend against any thereof.

                  (c) With regard to all Collateral so collected, sold or
otherwise disposed of, to the extent permitted by applicable law, Lender shall
have absolute discretion as to the time of application of any such proceeds,
moneys or balances in accordance with this Agreement, first, to the settlement
of all Liens on the Collateral prior to Lender's Lien; second, to the payment of
all Collection Costs; and third, to the payment of all Obligations, and, in case
of any deficiency, Lender may collect such deficiency from any Borrower
(provided however, nothing in this provision shall be construed in derogation or
limitation of any guaranty of payment or used to construe any guaranty of
payment as being merely a guaranty of collection).

                  (d) Notwithstanding anything in this Agreement or any other
Credit Document to the contrary, Lender's declaration of default and exercise of
remedies with respect to any swap agreement (as defined in 11 U.S.C. ss.101)
between an Obligor and Lender shall not be governed by this Agreement or any
other Credit Documents, but rather by the applicable swap agreement (as defined
in 11 U.S.C. ss.101).

         SECTION 6.04. RECEIVER. If an Event of Default shall occur and be
continuing, Lender shall be entitled as a matter of right and to the extent
permitted by law, without notice to any Obligor, and without regard to the
adequacy of security, to the immediate ex parte appointment of a Receiver by a
court having jurisdiction in order to carry out all rights and remedies
available to Lender upon such Event of Default, and to manage, protect and
preserve the Collateral, and any other Property of any Borrower and continue to
operate or liquidate any Borrower's business and to collect all revenues and
profits thereof and apply the same to the payment of all expenses and other
charges of such receivership, custodianship or similar appointment, including
compensation of the Receiver and to the payment of the Obligations, and to the
payment of such other claims and expenses as may appear appropriate. If Lender
shall apply for the appointment of, or the taking of possession by, a Receiver,
to hold, operate or liquidate all or any substantial part of the properties or
assets of any Borrower, such Borrower hereby consents to any such appointment
and taking of possession. Each Borrower shall deliver to any Receiver so
appointed upon Lender's request all original Records, and any other records,
books, and other information regarding the Collateral, and any other Property of
such Borrower and the operations of the business of such Borrower.

         SECTION 6.05. WAIVERS. Each Borrower waives presentment, demand, notice
of dishonor, and protest, and all demands and notices of any action taken by
Lender under this Agreement, except as otherwise provided herein, are hereby
waived, and any indulgence of


                                      -65-
<PAGE>

Lender, substitution for, exchange of or release of collateral, or addition or
release of any person liable on the collateral is hereby assented and consented
to and shall not operate or be claimed to operate to release or exonerate any
other collateral or person or any claim of Lender.

         SECTION 6.06. ARBITRATION.

                  (a) Upon demand of any party hereto, whether made before or
after institution of any judicial proceeding, any claim or controversy arising
out of, or relating to this letter or the Credit Documents between the parties
hereto (a "DISPUTE") shall be resolved by binding arbitration conducted under
and governed by the Commercial Financial Disputes Arbitration Rules (the
"ARBITRATION RULES") of the American Arbitration Association (the "AAA") and the
Federal Arbitration Act. Disputes may include, without limitation, tort claims,
counterclaims, disputes as to whether a matter is subject to arbitration, claims
brought as class actions, or claims arising from documents executed in the
future. A judgment upon the award may be entered in any court having
jurisdiction. Notwithstanding the foregoing, this arbitration provision does not
apply to disputes under or related to swap agreements.

                  (b) Special Rules. All arbitration hearings shall be conducted
in the city in which the office of Lender first stated above is located. A
hearing shall begin within 90 days of demand for arbitration and all hearings
shall be concluded within 120 days of demand for arbitration. These time
limitations may not be extended unless a party shows cause for extension and
then for no more than a total of 60 days. The expedited procedures set forth in
Rule 51 ET SEQ. of the Arbitration Rules shall be applicable to claims of less
than $1,000,000. Arbitrators shall be licensed attorneys selected from the
Commercial Financial Dispute Arbitration Panel of the AAA. The parties do not
waive applicable Federal or state substantive law except as provided herein.

                  (c) Preservation and Limitation of Remedies. Notwithstanding
the preceding binding arbitration provisions, the parties agree to preserve,
without diminution, certain remedies that any party may exercise before or after
an arbitration proceeding is brought. The parties shall have the right to
proceed in any court of proper jurisdiction or by self-help to exercise or
prosecute the following remedies, as applicable: (i) all rights to foreclose
against any real or personal property or other security by exercising a power of
sale or under applicable law by judicial foreclosure including a proceeding to
confirm the sale; (ii) all rights of self-help including peaceful occupation of
real property and collection of rents, set-off, and peaceful possession of
personal property; and (iii) obtaining provisional or ancillary remedies
including injunctive relief, sequestration, garnishment, attachment, appointment
of receiver and filing an involuntary Lenderruptcy proceeding. Any claim or
controversy with regard to any party's entitlement to such remedies is a
Dispute. Each party agrees that it shall not have a remedy of punitive or
exemplary damages against the other in any Dispute and hereby waive any right or
claim to punitive or exemplary damages they have now or which may arise in the
future in connection with any Dispute, whether the Dispute is resolved by
arbitration or judicially. The parties acknowledge that by agreeing to binding
arbitration they have irrevocably waived any right they may have to a jury trial
with regard to a Dispute.

                                  MISCELLANEOUS

         SECTION 7.01. FURTHER ASSURANCES. Each Borrower shall execute and
deliver to Lender such further assurances of this Agreement and the matters
contemplated by this Agreement and the other Credit Documents, including any
Lien Notices in favor of Lender, promptly from time to time upon Lender's
written request.

         SECTION 7.02. SUCCESSORS AND ASSIGNS. This Agreement and the other
Credit Documents shall be binding upon and inure to the benefit of Lender and
its successors and assigns and any holders of the Notes. No Borrower shall,
without Lender's prior written consent, which consent may be withheld in
Lender's discretion, assign any of such Borrower's rights under this Agreement
or any of the other Credit Documents to any Person, and any attempt of such an
assignment by any Borrower without Lender's prior written consent shall be void.
Lender may sell or assign to any financial institution or institutions, and such
financial institution or institutions may further sell or assign a participation
interest (undivided or divided) in, Lender's rights and benefits under this
Agreement and the other Credit Documents, and to the extent of that assignment
such assignee or assignees shall have the same rights and benefits against each
Borrower under this Agreement and the other Credit Documents as it or they would
have had if such assignee or assignees were Lender making the Loans. Each
Borrower shall promptly upon Lender's request furnish confirmation in writing to
any such assignees such information as Lender or any such assignee may request
regarding any matters, or the status thereof, relating to the Loans, the Notes,
this Agreement, the other Credit Documents, or any Obligor Information. Lender
may from time to time in its discretion appoint agents for the purpose of
servicing and administering this Agreement and the transactions contemplated
hereby and enforcing or exercising any rights or remedies of Lender provided
under this Agreement and under the other Credit Documents or otherwise. In
furtherance of such agency, Lender may from time to time direct that each
Borrower and any other Obligor provide notices, certificates, reports, and other
Obligor Information contemplated by this Agreement (or duplicates thereof) to
such agent. Each Obligor consents to the appointment of any such agent and
agrees to provide all such notices, certificates, reports, and other Obligor
Information to such agent and to otherwise deal with such agent acting on behalf
of Lender in the same manner as would be required if dealing with Lender itself
and Lender agrees to give each Borrower notice of the appointment of any such
agent.

         SECTION 7.03. SEVERABILITY. Any provision of this Agreement prohibited
by the laws of any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition, or modified to conform with such laws,
without invalidating the remaining provisions of this Agreement, and any such
prohibition in any jurisdiction shall not invalidate such provisions in any
other jurisdiction.

                                      -67-
<PAGE>

         SECTION 7.04. GOVERNING LAW. This Agreement and the other Credit
Documents and the rights and obligations of the parties hereunder and thereunder
shall be governed by and construed and interpreted in accordance with the laws
of the Commonwealth of Virginia (excluding Virginia conflict of laws rules),
including all matters of construction, validity and performance, regardless of
the location of the parties or any Property, excepting, however, that the UCC
(or decisional law) of a jurisdiction other than Virginia may provide the method
of perfection of liens and security interests created under this Agreement and
the other Credit Documents.

         SECTION 7.05. JURISDICTION; VENUE; SERVICE. Each Borrower irrevocably
consents to the non-exclusive personal jurisdiction of the courts of the
Commonwealth of Virginia and, if a basis for federal jurisdiction exists, the
non-exclusive jurisdiction of the United States District Court for the District
of Virginia. Each Borrower agrees that venue shall be proper in any circuit
court of the Commonwealth of Virginia selected by Lender or, if a basis for
federal jurisdiction exists, in any Division of the United States District Court
for the District of Virginia. Each Borrower waives any right to object to the
maintenance of any suit or claim in any of the state or federal courts of the
Commonwealth of Virginia on the basis of improper venue or of inconvenience of
forum. Any suit or claim brought by any Borrower against Lender that is based,
in whole or in part, directly or indirectly, on this Agreement or any matters
relating to this Agreement or the other Credit Documents, shall be brought in a
court only in the Commonwealth of Virginia. No Borrower shall file any
counterclaim against Lender in any suit or claim brought by Lender against such
Borrower in a jurisdiction outside of the Commonwealth of Virginia unless under
the rules of the court in which Lender brought such suit or claim the
counterclaim is mandatory, and not permissive, and would be considered waived
unless filed as a counterclaim in the claim or suit instituted by Lender against
such Borrower. Each Borrower agrees that any forum outside the Commonwealth of
Virginia is an inconvenient forum and that a suit brought by such Borrower
against Lender in any court outside the Commonwealth of Virginia should be
dismissed or transferred to a court located in the Commonwealth of Virginia.
Each of the parties hereto further irrevocably consents to the service of
process out of any of the aforementioned courts in any such action or proceeding
by the mailing of copies thereof by registered or certified mail, postage
prepaid, to it at the address set out for notices in this Agreement, such
service to become effective thirty (30) days after such mailing. Nothing herein
shall affect the right of Lender to serve process in any other manner permitted
by law or to commence legal proceedings or to otherwise proceed against any
Borrower or any other Person in any other jurisdiction.

         SECTION 7.06. COUNTERPARTS. This Agreement may be executed in any
number of counterparts, each of which when so executed and delivered shall be an
original, but all of which shall constitute one and the same instrument. It
shall not be necessary in making proof of this Agreement to produce or account
for more than one such counterpart.

         SECTION 7.07. SURVIVAL. All representations and warranties and
indemnities made by any Borrower herein shall survive delivery of the Notes and
the making of the Loan.

                                      -68-

         SECTION 7.08. NOTICES. Any notice required or permitted by or in
connection with this Agreement shall be in writing and shall be made by
telecopy, or by hand delivery, or by overnight delivery service, or by certified
mail, return receipt requested, postage prepaid, addressed to the parties at the
appropriate address set forth below or to such other address as may be hereafter
specified by written notice by the parties to each other. Notice shall be
considered given as of the earlier of the date of actual receipt, or the date of
the telecopy or hand delivery, one (1) calendar day after delivery to an
overnight delivery service, or three (3) calendar days after the date of
mailing, independent of the date of actual delivery or whether delivery is ever
in fact made, as the case may be, provided the giver of notice can establish
that notice was given as provided herein. Notwithstanding the aforesaid
procedures, any notice or demand upon any Obligor, in fact received by such
Obligor, shall be sufficient notice or demand. Each undersigned Obligor (other
than Borrower) hereby appoints Borrower as his, her or its agent for purposes of
receiving notices under this Agreement and the other Credit Documents, so that
notices given to Borrower shall be fully effective notice to Borrower and to
each such other undersigned Obligor (other than Borrower).

         SECTION 7.09. LENDER APPOINTED ATTORNEY-IN-FACT. Each Borrower hereby
appoints Lender as such Borrower's attorney-in-fact, with power of substitution,
which appointment is coupled with an interest and irrevocable but which
appointment shall not be exercised except during the continuance of any Event of
Default hereunder, to do each of the following in the name of such Borrower or
in the name of Lender or otherwise, for the use and benefit of Lender, but at
the cost and expense of such Borrower, and with or without notice to such
Borrower: (a) notify the Account Debtors to make payments directly to Lender,
and to take control of the cash and non-cash proceeds of any Collateral; (b)
compromise, extend, or renew any of the Collateral or deal with the same as it
may deem advisable; (c) release, make exchanges, substitutions, or surrender of
all or any part of the Collateral; (d) remove from such Borrower's place of
business all Records relating to or evidencing any of the Collateral or without
cost or expense to Lender, make such use of such Borrower's places of business
as may be reasonably necessary to administer, control and collect the
Collateral; (e) repair, alter or supply goods, if any, necessary to fulfill in
whole or in part the purchase order or similar order of any Account Debtor; (f)
demand, collect, receipt for and give renewals, extensions, discharges and
releases of any of the


                                      -69-
<PAGE>

Collateral; (g) institute and prosecute legal and equitable proceedings to
enforce collection of, or realize upon, any of the Collateral; (h) settle,
renew, extend compromise, compound, exchange or adjust claims with respect to
any of the Collateral or any legal proceedings brought with respect thereto; (i)
endorse the name of such Borrower upon any Items of Payment relating to the
Collateral or upon any proof of claim in Lenderruptcy against an Account Debtor;
(j) institute and prosecute legal and equitable proceedings to reclaim any of
the goods sold to any Account Debtor obligated on an Account at a time when such
Account Debtor was insolvent; and (k) receive and open all mail addressed to
such Borrower and notify the postal authorities to change the address for the
delivery of mail to such Borrower to such address as Lender may designate.

         SECTION 7.10. REMEDIES CUMULATIVE. No failure or delay on the part of
Lender in exercising any right, power or privilege hereunder or under any other
Credit Document and no course of dealing between any Obligor and Lender shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right, power or privilege hereunder or under any other Credit Document preclude
any other or further exercise thereof or the exercise of any other right, power
or privilege hereunder or thereunder. The rights and remedies provided herein
are cumulative and not exclusive of any rights or remedies which Lender would
otherwise have. No notice to or demand on any Borrower in any case shall entitle
such Borrower or any Obligor to any other or further notice or demand in similar
or other circumstances or constitute a waiver of the rights of Lender to any
other or further action in any circumstances without notice or demand.

         SECTION 7.11. AMENDMENTS, WAIVERS AND CONSENTS. Neither this Agreement
nor any other Credit Document nor any of the terms hereof or thereof may be
amended, changed, waived, discharged or terminated unless such amendment,
change, waiver, discharge or termination is in writing signed by Lender.

         SECTION 7.12. WAIVERS OF CLAIMS; CONSEQUENTIAL AND PUNITIVE DAMAGES.
Each Borrower and Lender hereby waive to the fullest extent permitted by law all
claims to consequential and punitive damages in any lawsuit or other legal
action brought by either of them against the other of them in respect of any
claim between them arising under this Agreement, the other Credit Documents, or
any other agreement or agreements between them at any time, including any such
agreements, whether written or oral, made or alleged to have been made at any
time prior to the date hereof, and all agreements made hereafter or otherwise,
and any and all claims arising under common law or under any statute of any
state or the United States of America, whether any such claims be now existing
or hereafter arising, now known or unknown. In making this waiver Lender and
each Borrower acknowledge and agree that there shall be no claims for
consequential or punitive damages made by Lender against any Borrower and there
shall be no claims for consequential or punitive damages made against Lender by
any Borrower. Lender and each Borrower acknowledge and agree that this waiver of
claims for consequential damages and punitive damages is a material element of
the consideration for this Agreement.

         SECTION 7.13. NO THIRD PARTY BENEFICIARIES. There shall be no third
party beneficiaries of this Agreement.

                                      -70-
<PAGE>

         SECTION 7.14. ENTIRE AGREEMENT. Each Borrower agrees that the Credit
Documents are a complete and exclusive expression of all the terms of the Loans
and agrees that all prior agreements, statements, and representations, whether
written or oral, which relate in any way to the Loans are hereby superseded and
shall be given no force and effect, and that no promise, inducement, or
representation has been made to any Obligor which relates in any way to the
Loans, other than what is expressly stated in the Credit Documents. Each
Borrower has executed the Credit Documents in full, understands the terms
therein, and is executing this Agreement after the opportunity to have full
consultation with counsel of such Borrower's choice.

         SECTION 7.16. WAIVER OF JURY TRIAL. EACH BORROWER AND LENDER HEREBY
WAIVE ALL RIGHT TO TRIAL BY JURY OF ANY AND ALL CLAIMS BETWEEN THEM OF ANY TYPE,
INCLUDING CLAIMS ARISING UNDER AND/OR RELATING IN ANY WAY TO THIS AGREEMENT
AND/OR THE OTHER CREDIT DOCUMENTS AND/OR THE TRANSACTIONS CONTEMPLATED BY THE
CREDIT DOCUMENTS. EACH BORROWER AND LENDER ACKNOWLEDGES THAT THIS IS A WAIVER OF
A LEGAL RIGHT AND THAT THIS WAIVER IS MADE KNOWINGLY AND VOLUNTARILY AFTER
CONSULTATION WITH COUNSEL OF ITS CHOICE. ALL CLAIMS ARISING UNDER THIS AGREEMENT
AND/OR THE OTHER CREDIT DOCUMENTS AND/OR THE TRANSACTIONS CONTEMPLATED BY THE
CREDIT DOCUMENTS SHALL BE TRIED BEFORE A JUDGE OF A COURT HAVING JURISDICTION,
WITHOUT A JURY.

         SECTION 7.17. JUDGMENT CURRENCY. (a) If, for the purposes of obtaining
judgment in any court, it is necessary to convert a sum due hereunder or under
the Notes or any other Credit Document from a currency ("ORIGINAL CURRENCY") to
another currency ("OTHER CURRENCY"), the parties hereto agree to the fullest
extent they may effectively do so, that the rate of exchange used shall be that
at which Lender could in accordance with normal banking procedures purchase the
Original Currency with the Other Currency on the second Business Day preceding
that on which such final judgment is given.

                  (b) The obligation of any Borrower in respect of any sum due
in the Original Currency from any Borrower to Lender hereunder or under the
Notes shall, notwithstanding any judgment in any Other Currency, be discharged
only if and to the extent that on the Business Day following receipt by Lender
of any sum adjudged to be so due in such Other Currency, Lender may in
accordance with normal Banking procedures purchase such amount of the Original
Currency with such Other Currency which it could have purchased on the second
Business Day preceding that on which the final judgment referred to in clause
(a) above is given. If the amount of the Original Currency so purchased is less
than the amount of the Original Currency that Lender could have purchased on the
second Business Day preceding that on which such final judgment is given, each
Borrower agrees, as a new and separate obligation and notwithstanding any such
judgment, to indemnify Lender against, and pay Lender on demand, such
difference, and if the amount of the Original Currency so purchased exceeds the
amount of the Original Currency which Lender could have purchased on the second
Business Day


                                      -71-
<PAGE>

preceding that on which such final judgment is given, Lender agrees to remit to
such Borrower such excess.

         SECTION 7.18. WAIVER OF IMMUNITY. Each Borrower hereby represents,
warrants and agrees that to the extent that any Borrower or any of such
Borrower's property and assets may have or hereafter acquire any right of
sovereign or other immunity from suit, court jurisdiction, attachment in aid of
execution of judgment, set-off, execution or other legal process, such Borrower
hereby irrevocably waives, to the fullest extent permitted by law, such right of
immunity with respect to such Borrower's obligations hereunder and with respect
to legal proceedings to enforce the same and to enforce any judgment rendered in
such proceedings.

         SECTION 7.19. PUBLICITY. Lender may, in Lender's discretion and at
Lender's expense, publicize or otherwise advertise by so-called "tombstone"
advertising or otherwise Lender's financing transactions with Borrowers and
Guarantors. Lender may include references to Borrowers and Guarantors (and may
use any logo or other distinctive symbol associated with Borrowers or
Guarantors), and the transactions contemplated by this Agreement, in connection
with any advertising, promotion, or marketing undertaken by Lender.
