Item 1.   Business

Company Overview
- ----------------

     Pharmaceutical Product Development, Inc. and its subsidiaries (collectively
the "Company") provide a broad range of research and development and consulting
services in the life and discovery sciences segments.  PPD Development, Inc. is
the Company's life sciences subsidiary.  The Company believes that PPD
Development 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
pharmaceutical research and development outsourcing market.

  Life Sciences Group

     The Company's Life Sciences Group provides services through PPD

products into the market faster and to maximize the period of marketing
exclusivity and the economic return for those products.  In addition, PPD
Development's integrated services offer its clients a variable cost alternative
to the fixed costs associated with internal drug development.  PPD Development'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 global 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,
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:
TableTrans(R), which automates data transformation; CrossGraphs(R), which
provides graphical displays of complex research data; Resolve(TM), which manages
data queries to investigator sites; and Classify(TM), which manages global

enhancing objectives.

     During 1998, the Life Sciences Group also included Intek Labs, Inc., which
the Company 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 pharmacogenetic services for clinical trials.  In February 1999, Intek
became a subsidiary of PPGx, Inc., 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.
The Company believes that pharmacogenomics is becoming widely adopted as a drug
discovery and development tool and increasingly important as part of an
individual's diagnosis and treatment regimen. The Company owns a minority
position in PPGx, with the option to increase its ownership share at any time.
The Company also has exclusive marketing rights to PPGx pharmacogenomics
products and services, sold under the brand name, Pharmacogenomic Solutions(TM).

  Discovery Sciences Group

     PPD Discovery, Inc. was established in June 1997 when the Company acquired
SARCO, Inc., a combinational chemistry company, and the GSX System, a functional
genomics platform technology.  PPD Discovery focuses on the discovery research
segment of the pharmaceutical research and development outsourcing market.  In
May 1998, the Company created PPD GenuPro, Inc., a wholly owned subsidiary,
which holds licenses to a number of compounds in the genitourinary field.  PPD
GenuPro manages and performs the discovery research and development of these
compounds and will then license these compounds to pharmaceutical or
biotechnology companies.  In May 1999, the Company formed PPD Virtual, a
subsidiary of the Company.  PPD Virtual provides consultant and management
services for product portfolio management, strategic development and commercial
product assessment.  At this time, PPD GenuPro was realigned as a division of
PPD Virtual.

  Environmental Sciences Group

     Prior to selling its environmental sciences segment on January 31, 1999,
the Company also provided environmental sciences services.  Environmental
sciences services included assessment and management of chemical and
environmental health risk, site investigation and remediation planning and
litigation support.  In addition to the industries mentioned above, the
environmental sciences segment also marketed services to clients in the
industrial, manufacturing and oil and gas industries.  The environmental
sciences segment marketed its services primarily in the United States and
Europe.  The results of operations of the environmental sciences segment for the
periods prior to its disposition are presented as discontinued operations in the
Company's financial statements.

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 drug 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.  The
Company provides all of these services 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

                                       2
<PAGE>

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 used internal programming resources
to produce much of the software used in their drug discovery, clinical
development and regulatory compliance processes.  Now these companies also seek
external sources, including the Company's PPD Informatics division, to meet
these automation needs both through custom application development and through
customization of commercial packaged software. We believe that our range of
technical experience in clinical research systems positions us well to provide
these services.

  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, Center for Medicines Research and Company's estimates indicate that
global research-based pharmaceutical and biotechnology companies invested
approximately $44 billion in R&D activities in 1999.  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 biological
targets, 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.

     PPD Discovery includes a chemical and preclinical technology company that
provides lead generation, lead prioritization and lead optimization services,
and computational and preclinical development resources to the pharmaceutical,
biotechnology, agrochemical and animal health industries.

     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 outsourced 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.  The clinical stage is 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 proposed clinical trials.  The design of these trials,
also referred to as the study protocols, is essential to the

                                       3
<PAGE>

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:

     .    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.

     .    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.

     .    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.

     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 might 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 1999, worldwide expenditures on research and development by
pharmaceutical and biotechnology companies are estimated to have been $44
billion, of which the Company estimates $10 to $12 billion was spent on drug
development activities which were outsourced.  The Company believes that
approximately $5.5 billion of such spending was on preclinical/laboratory and
clinical development.

                                       4
<PAGE>

     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.

     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 Development'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 might 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.

                                       5
<PAGE>

     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.  We strive to deliver 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 (1) capitalizing on its
managerial and operational strengths, (2) focusing on hiring and training its
staff, (3) focusing on its marketing initiatives, (4) developing its services in
healthcare economics and communications consulting, (5) pursuing strategic
acquisitions to enhance discovery and development services, (6) expanding
geographically, (7) pursuing opportunities provided by technological advances,
and (8) 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 Development 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 Development
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 Development 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, we encourage our employees to continually upgrade and
broaden their skills through internal and external training programs.  As new
technologies develop, we equip and train our employees to make use of such
technological innovations.

     Global Strategic Marketing Initiatives

     PPD Development focuses its integrated marketing and sales efforts on
companies within the pharmaceutical industry with product development and
clinical needs in the service segments and therapeutic areas in which the
Company specializes.  The sales staff concentrates on making direct contact with
assigned clients and represent PPD's capabilities across all PPD service
segments.  PPD Development's business development personnel consult with
potential clients early in the project consideration stage in order to determine
their requirements.  The business development representative along with the
appropriate operational personnel then invest significant time to determine the
optimal means to design and execute the potential client's product development
or clinical program

                                       6
<PAGE>

requirements. PPD Development's recommendations to the potential client with
respect to study design and implementation are an integral part of PPD
Development's bid proposal process and are an important aspect of the integrated
services PPD Development offers. PPD Development believes its preliminary
efforts relating to the evaluation of a proposed clinical protocol and
implementation plan enhances the opportunity for accelerated initiation and
overall success of the clinical trial after the contract has been awarded to PPD
Development.

     We market discovery services through centralized PPD corporate marketing
efforts to supplement localized marketing by scientists to scientists, with
support from appropriate outside consultants and internal PPD consultative
specialists.  We market the functional genomics technology (GSX) primarily to
large pharmaceutical companies, while combinatorial chemistry is directed more
toward biotechnology and virtual companies.

     The Company encourages and sponsors the participation of its personnel in a
variety of scientific endeavors, including the presentation of papers by its
professional staff at national and international professional trade association
meetings and major conferences, and the publication of scientific articles in
respected medical and pharmaceutical journals.  The Company believes such
activities advance and promote its reputation for professional excellence.  The
Company's core marketing and corporate communications plans include advertising
in trade journals, participation at scientific conferences, speakers' bureau,
direct mail/e-mail, presentation and detailing materials, educational symposia
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 Development offers programs integrating such analysis in clinical
development programs to support regulatory approval, as well as pricing,
marketing and reimbursement strategies.  While PPD Development's current focus
in this area is on its traditional client base within the pharmaceutical and
biotechnology industries, with respect to both drugs under development and
products already on the market PPD Development expects to extend such services
to payors and providers as well.

     Acquisitions

     The Company intends to 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 include complementary client lists, ability to
increase market share within and across clients, complementary therapeutic area
and service segment strengths, strategic geographic capabilities and particular
process expertise.

     Acquisitions involve numerous risks, including difficulties in the
integration 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 those
acquisitions will be successfully integrated into the Company's operations.

     Geographical Expansion

     PPD Development currently has operations in the Americas (the United
States, Canada and South America), Europe (including Eastern Europe), South
Africa, Asia and the Pacific Rim.  PPD Development 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 Development believes that optimizing the use of information technology
can accelerate the drug development process and yield valuable marketing
information.  PPD Development has broad experience in the use of information
technology in clinical trial management and offers a wide range of technology-
based services.

                                       7
<PAGE>

Services offered include initial market research and study design, accelerated
patient recruitment, remote monitoring and data acquisition, ongoing study
management, data analysis, outcomes research, patient and disease management,
and the submission of electronic New Drug Applications. The Company utilizes a
mixture of commercially available third-party systems and selected internally
developed software to offer its clients advanced technology for expediting the
drug development process.

Services Offered
- ----------------

   Life Sciences Group

     PPD Development 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 Development 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 Development is one of the industry's largest Phase I
providers, with clinical testing services conducted in its 220-bed unit in
Austin, Texas, its 70-bed unit located near Research Triangle Park, North
Carolina and its 50-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 might 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 the safety and effectiveness of new
analgesic compounds used in molar extractions.  Supporting the Phase I
operations in Austin is an in-house clinical laboratory.  The laboratory
performs analytical assays on volunteer specimens to ensure that each subject
qualifies for the study and is not adversely affected by a drug.  The fact that
the laboratory is housed in the same physical facility as the volunteers
guarantees fast response times to unexpected outcomes.  The unit is accredited
by the College of American Pathologists.  It also provides services to function
as a central laboratory for Phase II-IV studies.  Instruction manuals and
specimen collection kits are mailed to investigative sites, which then return
samples to the laboratory for processing and report generation.

     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.

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

     Laboratory Services

     PPD Development provides bioanalytical, product analysis and biodiscovery
services through its Good Laboratory Practice (GLP)-certified laboratories in
Richmond, Virginia and Middleton, Wisconsin.  PPD

                                       8
<PAGE>

Development's laboratories analyze biological fluid samples from animal and
human clinical studies. The latter includes those conducted by PPD Development's
Phase I units for drug and metabolite content and concentration. PPD Development
currently has over 850 validated assays available for its clients' use in
conducting laboratory analyses, qualifying PPD Development for a wide range of
assignments. PPD Development's laboratories also process fluid samples for pre-
clinical studies.

     The Company's Discovery Sciences 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.  Our 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 Development 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 Development'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 Development 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

   Virology                   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 Development'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 Development can
manage every aspect of the clinical trial in Phases II through IV of the

                                       9
<PAGE>

drug development process. Services offered include 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 Development monitors its clinical trials in compliance with government
regulations.  PPD Development 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
Development 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 Development 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 Development serves its clients in the critical area of study design by
applying its 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.

     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 Development
recruits investigators who contract directly with either the Company or its
client.  For large scale Phase IV trials, we use our Telecommunications Center
(TCC) for investigator recruitment.  The TCC integrates telephones, relational
databases, computerized scripts and customized tracking software for
investigator recruitment, and centralized management of large scale Phase IV
trials.  During 1999 the TCC staff recruited and obtained investigative review
board approval for over 5,000 sites in three months. 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 Development maintains and constantly expands and refines its
computerized database of over 24,000 investigators.  Information regarding PPD
Development'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 Development 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.

                                       10
<PAGE>

     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 Development 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 Development utilizes a number of
appropriate methods of accelerating patient recruitment.  This may involve PPD
Development'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 Development reviews data through visits by its field monitors to
investigative sites.  Field personnel receive orientation training and routine
updates on changes in federal study regulations and new company SOPs for quality
trial monitoring and reporting.  Field personnel are equipped with laptop
computers for the purpose of SOP and regulatory information updates as well as
report generation.

     PPD Development has monitored many clinical trials, including a number of
very large studies.  For example, PPD Development 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 500 investigational sites and total
enrollment of approximately 88,000 patients.  PPD Development has monitored
49,000 patients in 251 protocols since the beginning of the project in 1990.
There has also been over 2,300 pharmacy, regulatory and operational audits at
the sites.

     Clinical Data Management and Biostatistical Analysis

     The professionals who manage PPD Development'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 Development 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), 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 Development offers consulting
services relating to sample size parameters for patient enrollment, development
of data analysis plans and randomization schemes. During clinical trials, PPD
Development assists in the rapid acquisition of clean and accurate data.
Following completion of the clinical trials, PPD Development assists in report
preparation and FDA presentations. PPD Development's biostatisticians might
participate with clients in meetings with the FDA to present and defend
biostatistical analyses. PPD Development has expertise in electronically
capturing and integrating geographically diverse data. PPD Development uses
SAS(R), Oracle(R), Domain's Clintrial(TM), Oracle Clinical(TM), Clintrace(TM)
and other third party software, as specified by clients, combined with
customized programs developed by PPD Development.

     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 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

                                      11
<PAGE>

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 Development's involvement in a treatment IND
application might 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 Development 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 integrate with PPD Development's other
services to speed the process consistent with good service and regulatory
compliance.

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

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 a chemical technology and preclinical development
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.

     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.

     PPD Discovery includes a chemical and preclinical technology company that
provides lead generation, lead prioritization and lead optimization services,
and computational and preclinical development resources to the pharmaceutical,
biotechnology, agrochemical and animal health industries.  PPD Discovery has
developed synthesis protocols to produce numerous small-molecule combinatorial
libraries in the 5,000 to 10,000 component range.

                                       12
<PAGE>

PPD Discovery has developed the SAR-System(TM) software package to efficiently
manage library design, compound tracking (plate maps), ID assignment and ISIS
database interface. While focusing on enhancing lead compound activity, PPD
Discovery also emphasizes simultaneous improvement of physicochemcial and
pharmacokinetic parameters of lead compound(s). PPD Discovery offers drug
metabolism assays using LC/MS/MS technology, cytochrome P450 enzyme assays for
characterization of in vitro metabolic profiles and stability, and full service
in vivo pharmacokinetic ("PK") screening of single or multiple New Chemical
Entities ("NCEs") for the investigation of metabolism and preclinical PK in
animal models. PPD Discovery also works with sponsors to create customized
preclinical development plans which include screening studies to identify lead
compounds or compound families as well as studies necessary for a successful
IND.

     PPD Discovery's chemical and preclincial technology is located in
Middleton, Wisconsin and at a new, 61,000 square foot research facility in North
Carolina. PPD Discovery's research facilities are fully equipped to perform
solid and solution-phase combinatorial chemistry, custom synthesis, solution-

Discovery maintains full analytical and computational capabilities in support of
its combinatorial, medicinal chemistry, and preclinical technology activities.

     Products include base libraries, which are chemical compounds designed for
high throughput biological screening: focus libraries, which are custom designed
chemical libraries provided exclusively to a client: and preclinical in vitro an
in vivo assay technology.  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.  PPD Discovery's preclincial services department also
offers consulting in the area of preclinical product development.  PPD Discovery
works with clients to create custom preclincial development plans, which include
screening studies to identify lead compounds or compound families necessary for
a successful IND.

Clients and Marketing
- ---------------------

     The Company's Life Sciences Group provides services primarily to
pharmaceutical and biotechnology companies.  For the year ended December 31,
1999, approximately 85.5% of the Company's Life Sciences Group's net revenue was
attributable to clinical services and 14.5% to laboratory services.  For the
year ended December 31, 1999, net revenue of the Life Sciences Group was derived
approximately as follows:

</TABLE>

     During 1999, the Company provided services to 42 of the top 50
pharmaceutical companies in the world as ranked by 1998 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 the current trend
toward consolidation in these industries, general economic downturns 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 1999 and
1998, no single client contributed more than 10% of the Company's total net
revenue.  In 1999, the Company's ten largest clients accounted for approximately
41.8% of the Company's total net revenue and approximately 15.2% of the
Company's total 1999 net revenue was derived from clients located outside the
U.S., in particular in Europe and Japan.

Contractual Arrangements
- ------------------------

     Many of PPD Development's contracts are fixed price, with some variable
components, and range in duration from a few months to several years.  In other
contracts, PPD Development 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 Development
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 Development'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 decision to terminate the development of
the product or end the study.  Contracts might 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
- -------

     Our 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 some cases,
PPD Development 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 $353.8 million in
net revenue at December 31, 1999, compared to $291.7 million in net revenue at
December 31, 1998.

     PPD Development 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 the 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.  Also, the scope of a contract can change during the
course of a study.  PPD Development might not be able to fully realize its
entire 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 Development's large competitors
include Covance, Inc., Kendle International, Inc., Parexel International
Corporation, ICON, Phoenix International and Quintiles Transnational
Corporation.  PPD Development also competes against some medium-sized companies,
and 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
with specialty focuses, such as those therapeutically aligned, may compete
aggressively against larger CROs for clients.  Increased competition might lead
to price and other forms of competition that may adversely affect PPD
Development'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 Informatics has agreements with several of the major software vendors
in pharmaceutical applications (for example, Domain Pharma and Oracle).
Competitors for PPD Informatic's consulting services include major

                                       14
<PAGE>

consulting companies with pharmaceutical industry groups (for example, Andersen
Consulting, CSC and EDS) and smaller companies with a pharmaceutical industry
focus (for example, DataCeutics, Netforce and ISCG). Competitors for PPD
Informatic's software products include larger software vendors such as SAS, but
primarily are smaller, specialized software companies.

     The outsource chemistry and preclinical research industry consists of
several dominant providers and numerous smaller niche companies.  PPD Discovery
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.

     PPD Discovery 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, PPD Discovery'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.  This 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
indemnification vary from client to client and from trial to trial.  Although
most of PPD Development'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 might 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 $10.0 million per claim, with an annual aggregate policy limit
of $10.0 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 Development 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 Development
has established quality assurance controls at its laboratory facilities to
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 (1) complying with regulations governing the
selection of qualified investigators, (2) obtaining specific written commitments
from the investigators, (3) verifying that informed consent is obtained from
patients, (4) monitoring the validity and accuracy of data, (5) verifying drug
or device accountability, and (6) instructing investigators to maintain records
and reports.  For specified periods PPD Development must also maintain reports
for each study for

                                       15
<PAGE>

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 Development'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.

     PPD Development'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 Development 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 Development 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 trademarks, such as a design of PPD, The Power of
Selection(TM), Classify, Resolve(TM), Cross Graphs(R), TableTrans(R), First
Pass(TM), and others. In addition, the Company owns, co-owns or has licensed the
rights to eight issued U.S., eight issued foreign; 22 pending U.S., and 36
pending foreign patents.

     PPD Discovery has filed of over 20 patents for genes useful for drug
development, chemical compositions useful as therapeutics, and other drug
development related technology. In addition, PPD Discovery has expanded its
propriety rights by acquiring licenses to technology instrumental for drug
discovery and development. PPD Discovery holds licensing privileges related to
GSX technology and to bacterial assays for human cytochrome P450 metabolism.

     PPD Development 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, 1999, the Company had approximately 3,400 full-time
equivalent employees, of whom 3,150 were employed in the Life Sciences Group, 40
were employed in the Discovery Sciences Group and the remainder was in the
Company's corporate headquarters. Of the Company's employees, approximately 140
hold Ph.D., M.D., Pharm.D. or D.V.M. degrees and approximately 420 hold other
masters or other postgraduate degrees. None of the Company's employees are
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 the year ended
     December 31, 1995 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,
     1995.

(2)  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 would not be liable for
     payment.

(3)  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.

(4)  Revenues are presented net of subcontractor costs. See accompanying
     consolidated statements of operations.

(5)  The discontinued operations include the Company's environmental sciences
     segment sold in January 1999 and the write off of its remaining investment
     in PACE Incorporated during the fourth quarter of 1995. All periods
     presented have been restated to exclude the results of operations of both
     of the above businesses.

Item 7.  Management's Discussion and Analysis of Financial Condition and Results
         of Operations

Overview

     During 1999, the Company reported net income of $28.5 million, or $1.15 per
diluted share, compared to net income of $19.8 million, or $0.85 per diluted
share, during 1998.  Excluding non-recurring tax benefit and merger and
acquisition costs, the Company's adjusted net income of $25.3 million was 54.2%
higher than prior year adjusted net income, excluding merger and acquisition
costs and gain on sale of business, of $16.4 million.

     In March 1999, the Company acquired ATP, Inc. ("PPD ATP"), a health
information services company.  PPD ATP provides customized inbound and outbound
telecommunications programs targeting consumers and healthcare providers.  The
Company acquired all of the outstanding stock of PPD ATP in exchange for
approximately 876,000 shares of the Company's common stock.  This acquisition
was accounted for as a pooling of interests transaction.  Results of operations
for PPD ATP are included in the consolidated results of operations of the
Company beginning January 1, 1999.  Results of operations of the Company for the
periods prior to January 1, 1999 were not restated because PPD ATP's results of
operations for periods prior to January 1, 1999 were not material to the
Company's operating results for these periods.

     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 stock of its Intek subsidiary, and the
rights to a software license, for an 18.2% ownership interest in PPGx.  The
Company is accounting for the investment in PPGx under the cost method.  As of
December 31, 1999, the investment in PPGx was valued at $4.2 million and was
recorded in "Other Assets, net" on our balance sheet.  The Company acts as
guarantor on a $8.0 million revolving credit facility for PPGx.  The Company has
exclusive marketing rights to PPGx pharmacogenomics products and services and an
option to increase its ownership share in PPGx.

     Effective January 31, 1999, the Company sold its environmental sciences
segment to Environ Holdings, Inc., a new company formed by the management of the
environmental sciences segment.  The Company received cash of $1.2 million, a
note receivable in the amount of $7.0 million (for which payment was received in
the first quarter of 1999) and a note receivable in the amount of $18.0 million,
which is due over a 12-year period.  The Company has received all principal and
interest payments due on the ENVIRON note receivable through January 2000.  The
Company did not recognize a gain or loss as a result of the sale because the
sales price was equal to the book value of the net assets sold.  The Company
also 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 May 1998, the Company created GenuPro, Inc., a subsidiary of PPD that
holds a license to a number of compounds in the genitourinary field, which were
purchased from Eli Lilly & Co. in the second quarter of 1998. The Company
recorded an acquired in-process research and development charge of $3.2 million
in the second quarter of 1998 related to the purchase of these compounds because
the compounds were in the initial stage of research and development at the date
they were acquired.  GenuPro, Inc. is a part of 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 sales price was approximately $7.8 million in the form
of $5.3 million in cash and a promissory note for $2.5 million, which was to be
received over the five year period following the date of sale of CCCR.  The sale
resulted in a gain of approximately $1.1 million, which was recognized as other
income during the first quarter of 1998.  The Company has received all principal
and interest payments on the note receivable for the sale of CCCR, which were
due through January 2000.  As part of the sales agreement, the Company continued
to provide CCCR with certain clinical and administrative services for an agreed
upon amount through the first quarter of 1999.

Year Ended December 31, 1999 Versus Year Ended December 31, 1998

     Net revenue increased $67.0 million, or 28.4%, to $302.5 million in 1999
from $235.6 million last year.  The Life Sciences Group's operations accounted
for 99.1% of the Company's net revenue for 1999.  The Life Sciences Group
generated net revenue of $299.8 million, an increase of $65.1 million, or 27.8%,
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.  International net revenues increased $7.8
million to $44.8 million in 1999 from $36.3 million in 1998, which contributed
to the increase in net revenue by the Life Sciences Group during 1999.  PPD ATP,
which was acquired in March 1999, contributed $14.3 million to the increase in
net revenue by the Life Sciences Group during 1999.

     The Discovery Sciences Group generated net revenue of $2.8 million, an
increase of $1.8 million, or 197.8%, 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.  In addition, the
functional genomics division earned $0.9 million in revenues in 1999 from a
joint development and license agreement (signed during the fourth quarter of
1998, which extends through the second quarter of 2000).  We expect net revenue
to increase in the Discovery Sciences operations during 2000 due to agreements
signed in January 2000.

     Total direct costs increased 28.0% to $155.2 million in 1999 from $121.2
million last year and remained relatively constant as a percentage of net
revenue at 51.3% for the current year as compared to 51.5% last year.  The Life
Sciences direct costs increased to $147.4 million in 1999 as compared to $117.6
million in 1998.  The increased direct cost dollars resulted primarily from
increased personnel costs due to the increase in the size and number of
contracts in the Global CRO Phase II-IV division.  In addition, PPD ATP
contributed $7.0 million to the increase in the direct costs of the Life
Sciences Group during 1999.  The Life Sciences Group direct costs decreased as a
percentage of related net revenue to 49.2% from 50.1%.  This decrease is
principally due to the mix of levels of personnel involved in the contracts
performed, certain fixed costs being allocated over higher revenues and a
focused effort to control the increase in direct costs, as revenues increased.
The Discovery Sciences Group direct costs increased to $7.7 million in 1999 as
compared to $3.6 million in 1998.  This increase was primarily due to $3.5
million in additional costs for a Phase II trial associated with GenuPro in
1999.

     Selling, general and administrative ("SG&A") expenses increased 22.9% to
$95.6 million in 1999 from $77.8 million last year.  The increase is primarily
attributable to an investment in additional administrative personnel to support
the Company's expanding operations.  As a percentage of net revenue, SG&A
expenses decreased to 31.6% in 1999 from 33.0% last year.

     Total depreciation and amortization expense increased $2.5 million, or
20.5%, to $14.8 million from $12.3 million last year.  The increase was related
to the depreciation of the increased investment in property and equipment due
primarily to the acquisition of PPD ATP in March 1999 and the Company's growth.
The Company's capital expenditures were $23.2 million in 1999.  Expanded
capabilities in the Company's labs accounted for approximately 40.3% of this
capital investment, while the enhancement and expansion of information
technology capacities accounted for approximately 28.9% of this capital
investment.  The remaining capital expenditures were predominately incurred in
connection with the expansion of existing operations and the opening of new
offices.

     During the first quarter of 1999, the Company recorded merger costs of $0.2
million in connection with the acquisition of PPD ATP.  These costs were
primarily cash expenses, such as legal and accounting fees, related to this
transaction.

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

     Operating income increased $15.7 million to $36.7 million in 1999, as
compared to $21.0 million last year.  Excluding gain on sale of CCCR, merger
costs, and non-recurring tax benefits, the Company's adjusted operating income
of $36.9 million in 1999 was 52.6% higher than adjusted operating income of
$24.2 million last year.  As a percentage of net revenue, operating income of
12.1% in 1999 represents an improvement from 8.9% of net revenue last year.
These increases were primarily due to the Company's focus on controlling the
increase in both direct and administrative costs, as revenues increased.

     Net interest and other income increased $0.8 million, or 21.8% to $4.3
million for the year ended December 31, 1999 from $3.6 million last year.
Excluding the gain related to the sale of CCCR, net interest and

                                       24
<PAGE>

other income of $4.4 million in 1999 was $1.9 million higher than last year. The
increase was primarily the result of the increase in interest income of $2.0
million partially offset by $0.1 million in net interest expense related to an
investment transaction entered into in the fourth quarter of 1999. The Company
recognized $1.6 million in interest income related to the notes receivable from
CCCR and Environ Holdings. The Company expects to recognize an additional $1.6
million during 2000 from these notes.

     The Company recorded a loss from discontinued operations, net of income tax
expense, related to its environmental sciences segment, of $0.4 million in 1999,
as compared to income of $4.6 million in 1998.  The environmental sciences
segment was sold on January 31, 1999.

     The provision for income taxes increased $2.7 million, or 28.6%, to $12.2
million in 1999, as compared to $9.5 million last year.  The Company's effective
income tax rate decreased to 29.6% in 1999 from 38.4% last year primarily due to
an investment transaction entered into in the fourth quarter of 1999, which
created a significant capital gain.  The Company will offset this capital gain
with a capital loss carryforward, which had previously been fully reserved.  As
a result of the reversal of the valuation allowance on this capital loss
carryforward, the Company has recognized a tax benefit of approximately $3.8
million.

     Net income of $28.5 million in 1999 represents an increase of $8.7 million
over $19.8 million last year.  Net income per diluted share of $1.15 for 1999
compares to $0.85 in 1998.  Excluding the impact of the discontinued operations
in both years, the non-recurring tax benefits and merger charges in 1999 and the
gain on sale of CCCR and acquisition-related charges in 1998, the Company's 1999
net income of $25.3 million is 54.2% higher than net income of $16.4 million for
1998.

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 in 1997.  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 1997.  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 1997.  The growth in the Discovery
Sciences operations was primarily attributable to an increase in the number of
contracts in the combinatorial chemistry division.

     Total direct costs increased 25.3% to $121.2 million in 1998 from $96.8
million in 1997 and remained relatively constant as a percentage of net revenue
at 51.5% in 1998 from 51.6% in 1997.  The Life Sciences Group direct costs
decreased as a percentage of related net revenue to 50.1% in 1998 from 50.7% in
1997.  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 1998
as opposed to a half-year of operations being recorded in 1997.  (As discussed
previously, the Discovery Sciences Group was formed in June 1997 through the
acquisitions of SARCO and the GSX System).

     Selling, general and administrative ("SG&A") expenses increased 23.8% to
$77.8 million in 1998 from $62.8 million in 1997.  The increase is primarily
attributable to the investment in additional selling and administrative
personnel to support the Company's expanding operations.  As a percentage of net
revenue, SG&A expenses decreased slightly to 33.0% in 1998 from 33.5% in 1997.

     Total depreciation and amortization expense increased $1.4 million, or
13.2%, to $12.3 million in 1998 from $10.9 million in 1997.  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%.

     Acquired in-process research and development decreased $5.9 million, or
65.3%, to $3.2 million in 1998 from $9.1 million in 1997.  The 1999 acquired in-
process research and development charge resulted from the purchase of a license
to six genitourinary compounds from Eli Lilly & Co. during the second quarter of
1998.  The Company immediately expensed the costs of the acquisition of these
compounds because the compounds were in the initial phase of 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.

                                       25
<PAGE>

     Operating income increased $13.7 million, or 186.3%, to $21.0 million in
1998, from $7.3 million in 1997.  Excluding gain on sale of CCCR and merger
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, operating income of 8.9% in 1998 represents a
dramatic improvement from 3.9% of net revenue in 1997.

     Net interest and other income increased $2.1 million to $3.6 million in
1998 from $1.5 million in 1997.  Excluding the gain related to the sale of CCCR,
net interest and other income of $2.5 million in 1998 was $1.0 million higher
than in 1997.  The increase 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.

     Net income of $19.8 million in 1998 represents an improvement of $10.2
million over net income of $9.6 million in 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 costs in 1997, the Company's 1998 net income of $21.0 million is 36.1%
higher than net income of $15.5 million in 1997.

Liquidity and Capital Resources

     As of December 31, 1999, the Company had $61.2 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, 1999, the Company experienced a net
increase in cash flow from operating activities to $50.6 million as compared to
$23.6 million last year.  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 1999 period, net income of
$28.5 million, depreciation and amortization of $15.0 million and the net
decrease of $7.1 million in other assets and liabilities (which includes a $15.7
million increase in unearned income due to various contracts achieving billing
milestones partially offset by a $6.0 million increase in accounts receivable)
resulted in this increase in cash flow from operating activities.  The number of
days revenue outstanding in accounts receivable and unbilled services, net of
unearned income, were 64.0 and 75.1 days (excluding operations and related
balance sheet accounts of the discontinued division at December 31, 1998) as of
December 31, 1999 and December 31, 1998, respectively.  This decrease is a
result of a focused effort by management on improving the accounts receivable
collection process.

     For the year ended December 31, 1999, the Company's investing activities
used $22.0 million in cash.  Capital expenditures of $23.3 million and the
investment in PPGx of $3.5 million were partially offset by net cash received in
the sale of ENVIRON of $3.4 million, $0.7 million in cash received with the
acquisition of PPD ATP and $0.5 million received from the repayment of a note
receivable.

     For the year ended December 31, 1999, the Company's financing activities
provided $0.8 million in cash, as net proceeds from stock option exercises of
$6.2 million and the proceeds from long-term debt of $0.9 million related
primarily to PPD ATP's building loan were partially offset by $6.4 million in
net repayments of long-term debt.

     Working capital as of December 31, 1999 was $106.8 million compared to
$93.9 million at December 31, 1998.  Excluding the environmental sciences
segment from the balance sheet as of December 31, 1998, the adjusted working
capital would have been $75.7 million.  The increase in working capital as
compared to adjusted working capital was due primarily to the increase in cash
and cash equivalents of $27.2 million in 1999.

     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).

                                       26
<PAGE>

     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.

     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, 1999, the Company had $5.7 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.

     In August 1999, 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 0.625% per year.  Indebtedness under
the line is unsecured and subject to certain covenants relating to financial
ratios and tangible net worth. This credit facility expires in August 2000, at
which time any outstanding balance is due.  There is no amount outstanding under
this credit facility at December 31, 1999.

     In the fourth quarter of 1999, the Company entered into a short sale and
repurchase of U.S. Treasury bonds with a face value of $520 million based on
management's expectations that interest rates would rise between the date the
transaction was entered into and its maturity date of May 15, 2000.  The Company
is required to record these financial instruments at their net fair value on
each reporting date, with any changes in the fair value recorded as either
interest income or interest expense. The Company made a margin deposit of $2.6
million related to this transaction.  The Company recognized a loss of
approximately $0.1 million on this transaction in 1999.  The last interest
redetermination date on this transaction was on January 5, 2000.  The Company
was not required to recognize any additional loss on this transaction at the
interest redetermination date and no longer has any exposure for changes in
interest rates between January 5, 2000 and the maturity date of May 15, 2000.

     The Company expects to continue expanding its operations through internal
growth and strategic acquisitions.  The Company expects these 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 liquidity 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 might seek funds from
public or private issuances of equity or debt securities.

Year 2000 Compliance

     The Year 2000 issue was 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 could experience operating difficulties unless they were
modified or upgraded to adequately process information involving, related to or
dependent upon the four digit field.

     The Company recognized the need to ensure its operations would not be
adversely impacted by Year 2000 failures and had established an internal review
team to address the Year 2000 issue that encompassed 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 monitored the status of the
Company's Year 2000 remediation plans.  The process included an inventory and
assessment of affected equipment and software, development of remediation plans,
execution of those plans and testing of all technology affected by this issue.
In addition, the Company assessed the Year 2000 issue with significant suppliers
and clients.

     At December 31, 1999, the assessment process was 100% complete worldwide
for all equipment (including computer hardware and software technology) used
internally by the Company.  Remediation and testing was 100% complete for
critical systems and for non-critical systems.  All systems, regardless of
whether they required remediation, were tested to ensure Year 2000 compliance.
The Company assessed its significant suppliers in North

                                       27
<PAGE>

America and Europe to determine the extent to which the Company could be
vulnerable to third party failure to remediate Year 2000 compliance problems.
The Company communicated regularly with key suppliers and clients and responded
promptly to all requests for information regarding Year 2000 compliance.
Business contingency plans were developed to minimize the impact of outages
across our locations worldwide. In addition, a plan was developed to handle
yearend activities to ensure all critical functions were verified and
operational prior to start of business in the new year. Although there can be no
assurance, 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 used for remediation was approximately 11% in 1998 and 5% in
1999.  As of December 31, 1999, the Company had spent approximately $1.75
million on Year 2000 compliance.  Of the total amount that the Company spent,
$1.25 million was 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.

     At year end all systems were backed up and verified to be operational prior
to the resumption of business after the new year.  Only minor Year 2000 issues
were encountered which resulted in an insignificant amount of cost to the
Company.  These issues did not have an impact on the business and all issues
were resolved within the first week.  The Company has also not experienced any
third party supplier issues.  The Company remains alert to potential Year 2000
related issues that may occur in the future, but believes that there will be no
material impact on operations, liquidity or financial condition.

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, United States dollar or
Euros. 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 rates 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 transactions involving multiple
currencies, but these form only a small percentage of the Company's total
transactions.  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 international
operations have not accounted for a significant portion of total operations
(approximately 15% in 1999).  It is anticipated that those conditions will
persist at least through December 31, 2000.

     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, changes in the mix of services and the timing
of milestone payments under Discovery Sciences contracts.  Because 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 might 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%, 15% and 13% of the Company's net revenues for
the years ended December 31, 1999, 1998 and 1997, 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
37% of the Company's revenue from foreign operations during 1999.  Accordingly,
some exposure exists to potentially adverse movements in the pound sterling and
other foreign currencies.  The United Kingdom has traditionally had a relatively
stable currency.  It is anticipated that those conditions will persist for at
least through December 31, 2000.

     Additionally, the Company's consolidated financial statements are
denominated in U.S. dollars and, accordingly, changes in the exchange rates
between Company 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 Company is exposed to changes in interest rates on its cash
equivalents, short-term investments, the short sale and repurchase of U.S.
Treasury Bonds and amounts outstanding under note payable and lines of credit.
The Company's cash and cash equivalents and short-term investments are invested
in financial instruments with interest rates based on financial market
conditions.

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,
1999 and 1998, and the results of their operations and their cash flows for each
of the three years in the period ended December 31, 1999, in conformity with
accounting principles generally accepted in the United States.  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
auditing standards generally accepted in the United States, 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 development and consulting
services in the life sciences and discovery sciences segments. In the life
sciences segment, the Company provides worldwide clinical research and
development of pharmaceutical products and medical devices, biostatistical
analysis and analytical laboratory services. The discovery sciences services
include target identification and validation, compound creation, screening and
compound selection. The Company provides services under contract to clients in
the pharmaceutical, general chemical, agrochemical, biotechnology and other
industries. In addition, the Company performs discovery research on certain
compounds for which the Company holds a license. The Company markets its life
sciences services primarily in the United States and Europe. The Company's
discovery revenues have all been generated in the United States to date.

     Prior to selling its environmental sciences segment on January 31, 1999
(see Note 4), the Company also provided environmental sciences services.
Environmental sciences services included assessment and management of chemical
and environmental health risk, site investigation and remediation planning and
litigation support.  In addition to the industries mentioned above, the
environmental sciences segment also marketed services to clients in the
industrial, manufacturing and oil and gas industries.  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.

Merger Costs and Special Charges

     The Company recorded merger costs of $218 and $558 in connection with the
acquisitions of ATP in 1999 and Belmont Research, Inc., SARCO, Inc., and Intek
Labs, Inc. in 1997. These acquisitions were accounted for using the pooling of
interests method of accounting. These costs were primarily transaction expenses
related to these pooling transactions.

Acquired In-Process Research and Development Costs

     The Company recorded an acquired in-process research and development charge
of $3,163 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 costs of the acquisition of these compounds because they were in
the initial phase of development at the date of the acquisition 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 $9,112 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.

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.

1.   Summary of Operations and Significant Accounting Policies (Continued):

Revenue Recognition (Continued)

     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.

     A portion of the Company's revenue is derived from sale of software
licenses as well as support and maintenance, training and consulting services.
The Company adopted American Institute of Certified Public Accountants ("AICPA")
Statement of Position ("SOP") No. 97-2, "Software Revenue Recognition," as
amended by SOP No. 98-4 effective January 1, 1998. The adoption did not have a
material effect on the timing of the Company's revenue recognition or cause
changes to its revenue recognition policies.

     In December 1998, the AICPA issued Statement of Position No. 98-9,
"Modification of SOP No. 97-2, Software Revenue Recognition, with Respect to
Certain Transactions" ("SOP No. 98-9").  SOP No. 98-9 amends SOP No. 97-2 to
require recognition of revenue using the "residual method" in circumstances
outlined in SOP No. 98-9.  Under the residual method, revenue is recognized as
follows:  (1) the total fair value of undelivered elements, as indicated by
vendor specific objective evidence, is deferred and subsequently recognized in
accordance with the relevant sections of SOP No. 97-2 and (2) the difference
between the total arrangement fee and the amount deferred for the undelivered
elements is recognized as revenue related to the delivered elements.  SOP No.
98-9 is effective for transactions entered into in fiscal years beginning after
March 15, 1999.  Also, the provisions of SOP No. 97-2 that were deferred by SOP
No. 98-4 will continue to be deferred until the date SOP No. 98-9 becomes
effective.  The Company does not expect that the adoption of SOP No. 98-9 will
have a significant impact on the Company's results of operations or financial
position.

     Revenue from sale of software licenses totaled $313, $100 and $0 during the
years ended December 31, 1999, 1998 and 1997, respectively.  Revenue from
software licenses is recognized when there is evidence of an arrangement, the
product has been shipped, fees are fixed and determinable and collection of the
related receivable is probable.  Support and maintenance revenue totaled $90,
$29 and $0 during the years ended December 31, 1999, 1998 and 1997,
respectively.  Support and maintenance revenue is deferred and recognized
ratably over the service period.  Royalty revenue totaled $1,821, $889 and $349
during the years ended December 31, 1999, 1998 and 1997, respectively.  Royalty
revenue is comprised of royalties received from the sale of software licenses
and product maintenance by distributors of the Company's products.  Royalty
revenue is recognized when the Company is notified by the distributor of the
royalty and the amount is fixed and determinable.

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 consists of the following:

1.   Summary of Operations and Significant Accounting Policies (Continued):

Financial Instruments

     In the fourth quarter of 1999, the Company entered into a short sale and
repurchase of U.S. Treasury bonds with a face value of $520,000 based on
management's expectations that interest rates will rise between the date the
transaction was entered into and its maturity date of May 15, 2000. The Company
is required to record these financial instruments at their net fair value on
each reporting date, with any changes in the fair value recorded as either
interest income or interest expense. Net interest expense of $100 has been
recognized related to this transaction at December 31, 1999. The Company was
required to make a margin deposit of $2,600 related to this transaction.

Investigator Payments

     Billings and payments to investigators are based on predetermined
contractual agreements that may differ from the accrual of the related 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.

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 No. 98-1, "Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use," which requires
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.

Capitalized Software Costs

     Financial Accounting Standards Board Statement No. 86, "Accounting for the
Costs of Computer Software to be Sold, Leased or Otherwise Marketed," requires
the capitalization of certain software development costs once technological
feasibility has been established. The Company considers that technological
feasibility has been established once a working model of a product has been
established and tested. The establishment of technological feasibility and the
ongoing assessment of recoverability of capitalized software development costs
require considerable judgement by management concerning certain external factors
including, but not limited to, technological feasibility, anticipated future
gross revenue, estimated economic life and changes in software and hardware
technologies. To date, the Company has not capitalized any software development
costs, as amounts incurred subsequent to the establishment of technological
feasibility have not been material. Prior to the creation of a working model,
the Company expenses these costs.

1.   Summary of Operations and Significant Accounting Policies (Continued):

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. Goodwill is presented net of accumulated amortization at December 31,
1999 and 1998 of $5,064 and $4,926, respectively. The amortization charges for
each of the three years ended December 31, 1999, 1998 and 1997 were $1,005,
$1,235 and $1,401, respectively.

Other Assets

     Other assets are comprised of cost-method investments in certain technology
companies, other intangible assets, two notes receivable and a net long-term
deferred tax asset. Other intangible assets are being amortized over periods of
three to thirty-nine and a half 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, plant and equipment and intangibles at their fair value. No such
impairment was necessary during any of the three years ended December 31, 1999,
1998 and 1997.

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.

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, cash equivalents and U.S. Treasury Bonds. See Note 16.

1.   Summary of Operations and Significant Accounting Policies (Continued):

Concentration of Credit Risk (Continued)

     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 1999, 1998 or 1997.  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, 1999 and 1998 totaled $(2,154) and
$78, 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 per share information is based on the weighted average number of
common shares outstanding during the year. The computation of diluted income 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 the end of the year. Earnings per share for all periods presented
in the statements of operations conform to the provisions of SFAS No. 128.

Stock-Based Compensation

     The Company accounts for stock-based compensation based on the provisions
of Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees" ("APB No. 25"), which states that no compensation expense is recorded
for stock options or other stock-based awards to employees that are granted with
an exercise price equal to or above the estimated fair value per share of the
Company's common stock on the grant date. In the event that stock options are
granted with an exercise price below the estimated fair value of the Company's
common stock at the grant date, the difference between the fair value of the
Company's common stock and the exercise price of the stock option is recorded as
deferred compensation. Deferred compensation is amortized to compensation
expense over the vesting period of the stock option. The Company has adopted the
disclosure requirements of Statement of Financial Accounting Standards No. 123,
"Accounting for Stock-Based Compensation" ("SFAS No. 123"), which requires
compensation expense to be disclosed based on the fair value of the options
granted at the date of the grant. See Note 11.

1.   Summary of Operations and Significant Accounting Policies (Continued):

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.

Segment Reporting

     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 16 and 17.

Pensions and other Postretirement benefits

     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.

New Accounting Pronouncements

     In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Investments
and Hedging Activities," (SFAS No. 133").  SFAS No. 133 establishes accounting
and reporting standards for derivatives and hedging activities and supercedes
several existing standards.  SFAS No. 133, as amended by SFAS No. 137, is
effective for all fiscal quarters of fiscal years beginning after June 15, 2000.
The Company does not expect that the adoption of SFAS No. 133 will have a
material impact on the consolidated financial statements.

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 1999
presentation.

2.   Acquisitions:

Poolings

     In March 1999, the Company acquired ATP, Inc. ("PPD ATP"), a health
information services company.  PPD ATP provides customized inbound and outbound
telecommunications programs targeting consumers and health care providers.  The
Company acquired all of the outstanding stock of PPD ATP in exchange for
issuance of approximately 876 shares of the Company's common stock.  Outstanding
PPD ATP options were exchanged for options to acquire approximately 216 shares
of the Company's common stock.  This acquisition was accounted for using the
pooling of interests method.  Results of operations for PPD ATP are included in
the consolidated results of operations of the Company beginning January 1, 1999.
Results of operations of the Company for periods prior to January 1, 1999 were
not restated as PPD ATP's results of operations for the year ended December 31,

     In June 1998, the Company obtained a $50,000 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, 1999,
the Company had $5,700 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.

Operating Leases

     The Company is obligated under noncancellable leases expiring at various
dates through 2015 relating to its operating facilities and certain equipment.
Rental expense for all operating leases, net of sublease income, was $13,625,
$13,330 and $13,492 for the years ended December 31, 1999, 1998 and 1997,
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, 1999 are as follows:

            2000                   $ 15,819
            2001                     15,271

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 3,600 shares
of common stock. Under the Plans, the exercise price of each option granted must
equal the market price of the Company's stock on the date of grant and an
option's maximum exercise 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. The majority of the Company's options
vest over a period of three years.

11.  Stock Plans (Continued):

     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 and diluted net income 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 1999, 1998 and 1997: expected volatility of 81.1%, 60.3% and 58.7%,
respectively; risk-free interest of 6.19%, 5.75% and 6.0%, respectively; and
expected lives of five years.  The resulting estimated weighted average fair
value of options granted during 1999, 1998 and 1997 was $13.71, $13.49 and $9.48
per share, respectively. All options granted during the years ended December 31,
1999, 1998 and 1997 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.

1997, and changes during the years ending on those dates, is presented below:

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. 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 with the Company in 1996 were converted into
options to purchase the Company's common stock in accordance with the exchange
ratio provided for in the merger agreement.

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.

11.  Stock Plans (Continued):

     At December 31, 1999, $1,073 had been contributed to the ESPP relating to
unissued shares. Shares were not issued on December 31, 1999 since the market
had to be closed before a purchase price could be determined. On January 5,
2000, 106 shares were issued. During 1999, $2,048 had been contributed to the
ESPP and 98 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 $466 and $532 and is reflected
in the pro forma net income and diluted net income per share for 1999 and 1998,
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.

     The cumulative amount of undistributed earnings of foreign subsidiaries for
which the Company has not provided U.S. income taxes at December 31, 1999 was
$2,132. 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,
1999, 1998 and 1997 were $2,562, $2,201 and 1,945, respectively.

Pension Plans

     Pension costs are determined under the provisions of Statement of Financial
Accounting Standards No. 87, "Employers' Accounting for Pensions", 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.

13.  Employee Savings and Pension Plans (Continued):

     Prior to January 31, 1999, the Company maintained the APBI Environmental
Sciences Group, Inc. Pension Plan (the "ENVIRON 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 ENVIRON 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 ENVIRON Pension Plan
for the two years ended December 31, 1998 and 1997 was $697 and $638,
respectively. As of December 31, 1998, accrued pension cost, included in other
accrued expenses, was $651.

     All benefits under the ENVIRON Pension 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. The policy has a self-insured
retention per claim of $250. As of December 31, 1999 and 1998, there are no open
claims related to this coverage above the self-insured retention.

     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, 1999 and
1998 the Company maintained a reserve of approximately $1,752 and $1,483,
respectively, included in other accrued expenses on the consolidated balance
sheets to cover estimated open claims and claims incurred but not reported.

     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:

     The Company was related through common ownership with E.M. Associates,
Inc., which provided investigative board services to the Company. The Company
had transactions with E.M. Associates, Inc. of $37 in expenses for the year
ended December 31, 1997. There were no transactions with E.M. Associates during
the year ended December 31, 1999 or 1998.

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:

Accounts Receivable, Accounts Payable and Accrued Liabilities

     The carrying amount approximates fair value because of the short maturity
of these items.

Notes Receivable

     The notes receivable from the sale of CCCR and ENVIRON are carried at their
original value plus any accrued and unpaid interest. The Company believes the
carrying value approximates market on December 31, 1999.

16.  Fair Value of Financial Instruments (Continued):

Investment in DAS and PPGx

     The Company's investment in DAS and PPGx are recorded at $1,500 and $4,186,
respectively, at December 31, 1999. The Company's investment in DAS and PPGx are
accounted for using the cost method of accounting as the investment in DAS and
PPGx are not tradeable and the Company does not exert significant influence on
the operations of DAS or PPGx.

Derivative Financial Instrument

     The Company entered into a purchase and sale of a U.S. Treasury Bond with a
face value of $520,000 during the fourth quarter of 1999 with the same financial
institution. The Company has the legal right of offset with regard to the
obligation to pay for the cost of the U.S. Treasury Bond and the investment in
the U.S. Treasury Bond. The fair value of this net obligation of $100 at
December 31, 1999 was based on the quoted market price of these investments and
is determined as follows:

     Fair Value of U.S. Treasury Bond        $ 537,958
     Fair Value of Purchase Obligation        (538,058)
                                             ---------
                                             $    (100)
                                             =========

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 1999 and 1998, 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). 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 statement of 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 1999, 1998 and 1997 of $218, $3,163 and
$9,670, 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,
except for the 1999 tax benefit of $3,800 from the reversal of a portion of the
valuation allowance on the Company's capital loss carryforward which has been
specifically identified to the Life Sciences segment. Income from operations,
net income, depreciation and amortization, identifiable assets and capital
expenditures by principal business segment were as follows:

making such reimbursements.  All such amounts reimbursed with the proceeds of
Revolving Credit Loans shall be repayable in accordance with the terms of this
Agreement and the other Credit Documents.

          (c) Upon the occurrence of an Event of Default, all of Borrower's
reimbursement obligations under Letters of Credit, including Borrower's
obligations to reimburse Lender for amounts drawn under Letters of Credit and
Borrower's contingent obligations for amounts not yet drawn under outstanding
Letters of Credit, whether then due or otherwise, shall be immediately due and
payable by Borrower.  All amounts paid to Lender in respect of such contingent
obligations for amounts not yet drawn shall be held by Lender in the Letter of
Credit Collateral Account as cash collateral and applied by Lender to reimburse
Lender from time to time for amounts drawn under Letters of Credit until all
Letters of Credit have expired and Lender shall have been reimbursed for all
amounts drawn under Letters of Credit, and Borrower hereby assigns to Lender and
grants Lender a security interest in all amounts so held in any Letter of Credit
Collateral Account as cash collateral for Borrower's reimbursement obligations
under Letters of Credit.  If Borrower fails to pay such reimbursement
obligations immediately, including such amounts as are required to be held in
the Letter of Credit Collateral Account, Lender may, in Lender's discretion and
without any obligation to do so, and regardless of whether Borrower shall have
requested such Revolving Credit Loans or given Lender instructions to the
contrary, make Revolving Credit Loans to Borrower and directly apply the
proceeds of such Revolving Credit Loans to the payment of some or all of such
reimbursement obligations and to the funding of some or all such amounts to be
held in, and disbursed to Lender from, the Letter of Credit Collateral Account.
All such amounts paid or held from the proceeds of Revolving Credit Loans shall
be repayable in accordance with the terms of this Agreement and the other Credit
Documents.

          (d) Borrower's agreement and obligation to reimburse Lender for
amounts due

                                       26
<PAGE>

and payable as set forth in the preceding clauses of this Section (including all
such amounts in respect of contingent obligations) shall be absolute and
unconditional under all circumstances and shall be paid without 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,
including any set-off, counterclaim or defense based on any drawing documents
proving to be forged, fraudulent or invalid, or the legality, validity,
regularity or enforceability of such Letter of Credit or any Letter of Credit
Application, this Agreement, the Notes, or any other Credit Documents.

     SECTION 2C.06.  Instruction to Pay; Indemnification.
                     -----------------------------------

          (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

                                       27
<PAGE>

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 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.

                  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

                                       28
<PAGE>

at the Default Rate.

     SECTION 2D.04.  Omitted.

     SECTION 2D.05.  Unused Credit Fee. Borrower shall pay to Lender the Unused
                     -----------------
Credit Fee for each year or portion thereof prior to the termination of Lender's
obligations to extend Revolving Credit under this Agreement.  The accrued
portion of the Unused Credit Fee shall be due and payable to Lender in arrears
on each Quarterly Payment Date.  Borrower hereby authorizes Lender to debit
Borrower's account maintained with Lender 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 Lender 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. (S)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.

<PAGE>

     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.

     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 interbank 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

                                       30
<PAGE>

hold, then, if Lender 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 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.

          (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

                                       40

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.

               (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

                                       41
<PAGE>

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 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 nor any
Environmental Affiliate known to it, whether actively or passively, has
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, whether
actively or passively, has released, emitted, buried, leaked, or otherwise
disposed of Regulated Substances on any Property while owned, operated or leased
by any Borrower or any Environmental Affiliate known to it.

          (e)  To Borrower's knowledge, there are no asbestos containing
materials, polychlorinated biphenyls or radioactive substances located on
Property now owned, operated or leased by any Borrower.

          (f)  Neither any Borrower nor any Environmental Affiliate known to it
has operated a treatment, storage or disposal facility requiring a permit or

amended, or any comparable state laws, nor, to Borrower's knowledge, has any
Property of any Borrower or any Environmental Affiliate known to it been used

operated by Borrower or any Environmental Affiliate known to it which was
violative of any Environmental Law during such period of ownership, use or
operation.

          (h)  Neither any Borrower nor any Environmental Affiliate known to it

     SECTION 5.14.  Risk Management Agreements. No Obligor shall be a party to
                    --------------------------
any Risk Management Agreement, other than with an entity approved by Lender,
except as listed on Schedule 3.35 or as may be expressly required by a provision
                    -------------
of this Agreement.

connection with the Borrowers' application for the Loans was not true, accurate
and complete in all material respects when so furnished to Lender and on the
Effective Date; or

          (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,

                                       59
<PAGE>

schedules, and exhibits to the Credit Documents and all materials delivered to
Lender to satisfy any condition of this Agreement) is not true, accurate and
complete in all material respects when so furnished to Lender; or

          (j) The determination in good faith by Lender that a material adverse
change has occurred on a consolidated basis in the financial or operating

the most recent financial statements of the Obligors furnished to Lender in
connection with the Loans, or from the financial or operating condition or
business prospects of the Obligors as heretofore most recently disclosed to
Lender in writing by the Obligors, 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 against any
Obligor involving a liability of Two Hundred Fifty Thousand Dollars ($250,000)
or more in the aggregate which shall not have been satisfied, vacated,

any Person, including any Affiliate of Lender (other than the Obligations), or
shall breach any other terms, representations, warranties, covenants,
conditions, or other provisions applicable to any such Indebtedness if the
occurrence of any such default or breach would entitle the holder of such
Indebtedness to accelerate such Indebtedness or exercise any other remedies (and
the acceleration thereof or exercise of remedies would have a Material Adverse
Effect on the Borrower Group, and, if there is a cure period applicable to any
such breach or default, such breach or default shall not have been cured within

          (n) If any Obligor shall (i) apply for or consent to the appointment

          (p) the net loss through death, disability or voluntary or involuntary
termination of employment within a fiscal year of Principals (after taking into

gross revenues of the US Corporation in the most recent complete fiscal year; or

          (q) Borrower shall default in any swap agreement (as defined in 11

intended to be a Qualified Plan of its qualification under Section 401(a) of the

assessment against any Borrower or any ERISA Affiliate of a tax under Section
4980B of the Code; or (b) the Unfunded Benefit Liability of all of the Plans of
Borrower, and each ERISA Affiliate shall, in the aggregate, exceed an amount
that could reasonably be expected to have a Material Adverse Effect on Borrower
Group.

          (s) The provisions described in Section 6.01(c), (d) and (f) through
(j) shall not constitute Events of Default hereunder unless the events described
in such actions are not cured within thirty (30) days after notice from Lender;
provided that if Borrower commences a cure within the initial thirty (30) day
cure period and diligently pursues to cure the Default thereafter, Borrower
shall have up to sixty (60) days to cure such Default if it is not capable of
cure within thirty (30) days.

     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

                                       61
<PAGE>

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, 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 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 bank 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
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

                                       62
<PAGE>

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 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

                                       63
<PAGE>

to any swap agreement (as defined in 11 U.S.C. (S)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. (S)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 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 Agreement 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

                                       64
<PAGE>

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 bankruptcy 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.

                                  ARTICLE VII
                                  -----------
                                 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

                                       65
<PAGE>

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.

     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

                                       66
<PAGE>

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

     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

                                       68
<PAGE>

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.

     SECTION 7.14.  Entire Agreement. Borrower and Lender agree 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 7.15.  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 7.16.  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

                                       69
<PAGE>

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

     SECTION 7.17.  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 7.18.  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.

     SECTION 8.01.  Repayment of Term Loan and Subordination Agreement. As of
                    --------------------------------------------------
March 30, 1999, Borrower has refinanced the Term Loan (the "FUNB Term Loan")
with First Union National Bank ("FUNB") and repaid to Lender all amounts
outstanding with respect to the Term Loan.  In connection with the refinancing,
Lender entered into a Subordination and Intercreditor Agreement with FUNB dated
March 30, 1999 (the "Subordination Agreement") pursuant to which Lender has
agreed, inter alia, to subordinate the Seller Note to the FUNB Term Loan and to
        ----- ----
a revolving credit facility to be extended by FUNB to Borrower.  In
consideration of Lender's entrance into the Subordination Agreement, Borrower
covenants and agrees that, notwithstanding anything in this Restatement to the
contrary, (i) Lender has and shall have no obligation to make Revolving Credit
Loans to Borrower under Article II-A hereof or to issue any Letters of Credit to
or for the benefit of Borrower pursuant to Article II-C hereof, and (ii) Article
II-A and Article II-C hereof shall be of no further force or effect and this
Restatement shall interpreted as though such Sections do not appear and (iii) so
long as any Obligations (as such

                                       70
<PAGE>

term is defined in the FUNB Credit Agreement) remain outstanding from Borrower
to FUNB or FUNB shall have any obligation or commitment under the FUNB Credit
Agreement to take any action required to be taken by FUNB under the terms of the
FUNB Credit Agreement or to advance any monies to Borrower, Lender shall not (a)
make the Revolving Credit Loan to Borrower or (b) issue any Letter of Credit to
Borrower pursuant to the terms of Article II-C hereof.

     SECTION 8.02. Continuing Obligation to Subordinate. So long as the Seller
                   ------------------------------------
Note is outstanding in the event that the Lender does not extend to Borrower a
working capital line of credit upon expiration of the "Working Capital Loan" (as
defined and provided for in that certain Credit and Security Agreement dated as
of March 30, 1999 between FUNB and the Borrower), Lender will subordinate the
Seller Note to any third party working capital line or lines of credit which in
the aggregate do not exceed $3,500,000 and which is made upon the same terms and
conditions as the aforementioned "Working Capital Loan" in all material
respects.

     SECTION 8.03  EAGL Security.  As a condition of Lender continuing to make
                   ---------------
available funds advanced under the Seller Note, EHI shall cause its subsidiary
EAGL to provide Lender with security for the Borrowers' obligations arising
under the Seller Note. Such security shall comprise a Guaranty and a Mortgage
Debenture. EHI shall also deliver a Pledge of EAGL stock to Lender which shall
also secure Borrower's obligations arising under the Seller Note. It is
expressly understood and agreed that the security provided by EAGL to Lender
shall be governed by the terms and provisions of the Subordination Agreement.

                       THIRD AMENDMENT TO LOAN AGREEMENT


          THIS THIRD AMENDMENT TO LOAN AGREEMENT (this "Amendment") is made as
of the 11th day of November, 1999, by and among PHARMACEUTICAL PRODUCT
DEVELOPMENT, INC., a North Carolina corporation (together with its successors,
the "Borrower"); PPD DEVELOPMENT, INC., (the "Guarantor"); and WACHOVIA BANK,
N.A., a national banking association (together with its endorsees, successors
and assigns, the "Bank").

                               R E C I T A L S:
                               ---------------

          The Borrower, the Guarantor and the Bank are parties to a certain Loan
Agreement dated as of August 7, 1997, as amended pursuant to an Amendment to
Loan Agreement dated as of August 6, 1998 and a Second Amendment to Loan
Agreement dated as of January 30, 1999 (the "Loan Agreement").

          Capitalized terms used in this Amendment which are not otherwise
defined in this Amendment shall have the respective meanings assigned to them in
the Loan Agreement.

          The Borrower has requested certain modifications to the Loan Agreement
and the Bank is willing to modify the Loan Agreement subject to the terms,
provisions and conditions set forth in this Amendment.

          NOW, THEREFORE, in consideration of the Recitals, the mutual promises
herein contained and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Borrower, the Guarantor and
the Bank, intending to be legally bound hereby, agree as follows:

          SECTION 1.  Recitals.  The Recitals are incorporated herein by
                      --------
reference and shall be deemed to be a part of this Amendment.

          SECTION 2.  Amendments.  Effective from and after August 5, 1999, the
                      ----------
Loan Agreement is hereby amended as follows:

          2.1  Extension of Termination Date. The Termination Date is hereby
               -----------------------------
extended to August 3, 2000.

          2.2  Section 2.3 is hereby amended and restated to read in its
entirety as follows:

          2.3  Interest Rate. Loans outstanding hereunder shall bear interest at
               -------------
a per annum rate equal to (i) the LIBOR Rate plus the Applicable Margin or (ii)
                                             ----
the Base Rate plus the
              ----
<PAGE>

Applicable Margin, 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 Base
Rate plus three percent (3%). Interest will be payable in arrears on each
Interest Payment Date. As used herein, the term "Applicable Margin" shall mean,
for any day, an amount equal to: (1) five eighths of one percent (0.625%) on
each day that the aggregate principal amount of all Loans outstanding on such
day shall be less than the amount equal to fifty percent (50%) of the Commitment
on such day; and (2) eight hundred twenty-five thousandths of one percent
(.825%) on each day that the aggregate principal amount of all Loans outstanding
on such day is equal to or greater than the amount equal to fifty percent (50%)
of the Commitment on such day. For purposes of determining the Applicable Margin
for any day, a change in the principal amount of all outstanding Loans shall be
effective on the date of such change.

          2.4 In Section 6.9 subsections (f) and (g) are re-lettered as (g) and
(h), respectively, and a new subsection (f) is hereby added to Section 6.9 of
the Loan Agreement to read as follows:

          (f) Investments in and to ADoctorInYourHouse.com in an aggregate
     principal amount (on a cost basis) not to exceed $5,000,000 at any time;

          SECTION 3.  Conditions to Effectiveness.  The effectiveness of this
                      ---------------------------
Amendment and the obligations of the Bank hereunder are subject to receipt by
the Bank of the following:

          (a) an original Amendment, duly executed by the Borrower and the
     Guarantor;

          (b) a certificate of incumbency satisfactory to the Bank, certifying

     of the Borrower and the Guarantor authorized to execute and deliver this
     Amendment;

          (c) such other documents or items as the Bank or its counsel may
     reasonably request.

The effectiveness of this Amendment and the obligations of the Bank hereunder

condition which with notice or lapse of time, or both, would constitute an Event
of Default under the Loan Agreement, as hereby amended, shall have occurred and
be continuing, and the representations and warranties contained in Section 5 of
the Loan Agreement, as amended herein, are true on and as of the date hereof.

                      ------------------
above, the Loan Agreement shall remain unchanged and in full force and effect.

<PAGE>

herein contained shall waive, annul, alter, limit, diminish, vary or affect any
provision, condition, covenant or agreement contained in the Loan Agreement,
except as herein amended, nor affect or impair any rights, powers or remedies

would be required to be reported in response to Item 6(e) of Schedule 14A of
Regulation 14A promulgated under the Securities Exchange Act of 1934, as amended
("Exchange Act"), provided that such a Change in Control shall be deemed to have
occurred if any "person" (as such term is used in Sections 13(d) and 14(d)(2) of
the Exchange Act) is or becomes the beneficial owner, directly or indirectly, of
securities of PPD representing 50% or more of the combined voting power of PPD's
then outstanding securities.

          b.  "Constructive Termination" means a termination of Employee's
employment by PPD during the Covered Period initiated by Employee after (i) a
substantial diminution or alteration in the duties of Employee, (ii) a reduction
by PPD in Employee's base salary in effect on the date of the Change in Control,

is more than twenty-five (25) miles from Employee's primary work location prior
to the Change in Control. Constructive Termination specifically does not include
termination of Employee by reason of death, Disability or retirement at or after
age 65. Employee shall give PPD written notice of a Constructive Termination,
which notice shall provide a brief description of the circumstances which
Employee asserts gives rise to a right of Constructive Termination, and PPD

circumstances.

          c.  "Covered Period" means the time period commencing on the date of
and coincident with a Change of Control and ending one year thereafter.

          d.  "Disability" means the inability of Employee to perform his

days following written notice of the Board of Directors of such failure to
follow directions, or (iii) termination for cause as defined in and made
pursuant to a then effective employment agreement, if any, between Employee and
PPD.

     2.   Compensation  Upon Change of Control.     If during the Covered Period
          -------------------------------------
(i) PPD terminates Employee's employment for reason other than Termination for
Cause or (ii)  Employee's employment is terminated by reason of Constructive
Termination, Employee shall be entitled to the following compensation and
benefits:

          a.  PPD shall pay Employee a lump sum equal to Employee's W-2

(10) days after Employee's termination of employment.

          b.  PPD shall pay Employee any bonus or deferred compensation (whether
in the form of cash, stock or otherwise) accrued but unpaid as of Employee's
termination, said sum to be paid within ten (10) days after Employee's
termination of employment.

          c.  For a period of one-year after Employee's termination of
employment with PPD, PPD shall continue to pay for and provide existing employee
welfare benefits which Employee is receiving as of the date of termination of
employment, including life insurance, health, medical, dental, vision and
wellness, accidental death and dismemberment and disability benefits; provided,
however, that PPD's obligations under this clause shall terminate from the date
that Employee first becomes eligible after termination of employment with PPD
for similar coverage under another employer's plan.

          d.  Notwithstanding anything to the contrary in any award agreement
for non-qualified stock options, (i) all unvested shares underlying PPD non-
qualified stock options granted more than six months prior to the date of
Employee's termination shall become fully vested as of the date of Employee's
termination, and (ii) Employee shall continue to be treated under each award
agreement as if he was an employee of PPD until the first to occur of (x) the
third anniversary of Employee's termination of employment, or (y) the expiration
of the exercise period provided for therein; provided, however, in the event of
Employee's death or his disability (as disability is defined in the award
agreement) after the date of Employee's termination of employment hereunder, the
time for exercise after death or such disability prescribed in the award
agreement shall apply. The provisions of this subsection shall also apply to any
and all substitute stock options granted to Employee in exchange for Employee's
PPD non-qualified stock options to which this subsection applies.
