                                     PART I

ITEM 1.  BUSINESS.

     The terms "Company", "Registrant" or "AAI" in this Form 10-K include
Applied Analytical Industries, Inc., its corporate predecessors and its
subsidiaries, except where the context may indicate otherwise. The Company was
incorporated in 1986, although its corporate predecessor was founded in 1979.
AAI operates in two business segments which include a product development
business and a fee-for-service business.

     AAI is a specialty pharmaceutical company offering product development
opportunities and contract support services to the worldwide pharmaceutical and
biotechnology industries.

     AAI offers a wide range of pharmaceutical product development services
including comprehensive pharmaceutical formulation, testing and manufacturing,
in addition to the ability to take these newly formulated products into and
through the human clinical studies needed for marketing approval. AAI provides
these services both individually and on an integrated fashion to pharmaceutical
partners, as well as utilizing them on its internal proprietary projects and new
drug development activities. This business segment also provides a strong base
of resources, expertise and ideas that allows the Company to carry out its
internal product development activities successfully.

     AAI has contributed to the submission, approval or continued marketing of
client products worldwide, encompassing a wide range of therapeutic categories
and technologies. The Company believes that its ability to offer an extensive
portfolio of high quality drug development and support services enables it to
effectively compete as pharmaceutical and biotechnology companies look for a
mixture of standalone and integrated drug development solutions that offer
cost-effective results on an accelerated basis.

     The Company's product development business segment utilizes its
fee-for-service business segment as a well-established foundation for the
continued growth of AAI's internal product development program for new and
improved drugs and drug delivery technologies. This internal drug and drug
technology development business is funded initially by the Company, with the
Company later participating in the benefits of any potential commercial success
through licensing and royalty arrangements with partner pharmaceutical firms.

     The objective of the product development business is the growth and
utilization of a portfolio of proprietary technologies and patent and
intellectual property rights to bring products to market that are safer, more
effective, innovative, and more cost-efficient for the patient and health care
community. Moreover, growth in AAI's product development business will generate
more business, skills and relationships in the Company's fee-for-service
business. Success in both strategies will permit the AAI to continue to
establish itself as a specialty pharmaceutical company.

     In 1994, as part of its internal development program, the Company organized
Endeavor Pharmaceuticals Inc. ("Endeavor") to develop certain hormone
pharmaceutical products, focusing initially on several such products then under
development by AAI. The Company owns approximately 35% of the fully-diluted
common equity of Endeavor.

     In December 1996, the Company acquired L.A.B. Gesellschaft fur
pharmakologische Untersuchungen mbH & Co KG. ("L.A.B."). L.A.B. was a European
contract research and development organization headquartered in Neu-Ulm, Germany
with principal operating units in Neu-Ulm and Munich, Germany; Paris, France,
and Arnhem, Netherlands as well as a sales office in London, England. The former
L.A.B. operations are now included in the organization referred to as AAI
Europe. AAI Europe focuses on both clinical and non-clinical pharmaceutical
product development and provides services that include drug formulation
development; chemical analysis; Phase I clinical trial studies; bioanalytical
testing; and European regulatory consulting. AAI Europe also provides Phase
II-IV multi-center clinical trial studies focused in niche therapeutic areas
including hepatic disease, chemotherapeutics, and hormone replacement therapy.

     In September 1998, the Company acquired Kansas City Analytical Services,
Inc. (KCAS) a bioanalytical services company in the Kansas City, Kansas area.
KCAS offers bioanalytical testing of products to large

                                        1
<PAGE>   3

and small pharmaceutical development companies as well as to the Company's
internal product development program. The addition of KCAS significantly
increased AAI's bioanalytical testing capacity.

     On March 16, 1999, the Company merged with Medical & Technical Research
Associates, Inc., (MTRA) a clinical research organization located near Boston,
Massachusetts. MTRA offers clinical phase II -- IV studies predominately in the
US market to large and small pharmaceutical companies as well as to the
Company's internal product development program. The addition of MTRA adds
clinical Phase II -- IV capabilities in the United States and significantly
increases AAI's ability to provide clinical testing to U.S. customers and enable
the Company to compete for global clinical trial engagements. It also provides a
strong base of clinical trials skills for the Company's internal product
development program.

     The merger with MTRA was accounted for as a pooling-of-interests, and
accordingly, all prior period consolidated financial statements have been
restated to include the results of operations, financial position, and cash
flows of MTRA as though MTRA had always been a part of AAI. Results for the
years ended December 31, 1999, 1998 and 1997 represent the combined results of
AAI and MTRA.

PRODUCT DEVELOPMENT BUSINESS

     The Company dedicates a portion of its technical resources and operating
capacity to internal drug and technology development with the objective of
licensing marketing rights to third parties. It also provides product
development services for clients' new and existing products that generate
royalties, milestone payments and upfront fees for the Company.

     The Company does not independently commercialize products developed
internally or otherwise directly compete with its clients in the marketing or
distribution of products and, accordingly, believes that its internal
development efforts are complementary to its clients' development needs. The
Company's internal product and technology development program has resulted in
multiple product applications filed with the FDA and European regulatory
agencies. Many of these products have been licensed or sold. The internal
development program has also resulted in patents covering drug technology and
pending patent applications.

     Since 1993, the Company has significantly increased its investment in its
internal product development program. Because of the length of time required for
development and approval of pharmaceutical products, the Company has only
recently begun to recognize significant license revenue from its internal
development efforts. The Company anticipates that internal product development
revenues, including royalties and milestone license payments, will represent a
growing proportion of its revenue. However, there can be no assurance that
internal development projects will yield products that will be approved by the
appropriate regulatory authorities or will be attractive to potential clients.
Although there is a risk that any particular development project may not produce
revenues, the Company believes that the profit margins from successful drug and
technology development projects could potentially exceed the margins for
standard fee-for-service engagements. The Company seeks to pursue multiple drug
and technology development projects to manage risk in each particular effort.

     In 1994, as part of its internal development program, the Company organized
Endeavor with certain financial investors and an affiliate of Schering AG to
continue the development of certain generic hormone products then under
development by AAI. The Company assigned its rights to such products to Endeavor
in return for approximately 47% of Endeavor's equity during a private placement
of Endeavor stock, and the Company entered into a contract with Endeavor to
continue product development and clinical supply manufacture. AAI currently owns
approximately 35% of the fully diluted common equity of Endeavor. The Company
believes that such services are provided at terms that are no less favorable
than terms that would be obtained from an unrelated third party.

     The Company recently purchased certain product rights and validated
manufacturing equipment from Endeavor as consideration for reducing the Endeavor
outstanding receivable balance from approximately $2.9 million, including
work-in-progress, to $950,000.

     Endeavor is currently developing another product, in multiple dosage
strengths; however, there can be no assurance that such product will ultimately
be approved by the FDA. Endeavor does not directly market any
                                        2
<PAGE>   4

products and its revenues are dependent upon licensing fees and royalties from
third parties. Continued product development by Endeavor is dependent upon
revenues from additional capital funding.

     In 1995 the Company entered into an agreement with Aesgen, Inc. ("Aesgen"),
a company organized by the Company with an affiliate of Mayo Clinic, MOVA
Pharmaceutical Corporation and certain financial investors, to develop certain
pharmaceutical products. Six products developed by the Company for Aesgen have
been approved by the FDA. In 1996, the Company sold to Aesgen marketing rights
to a product being developed by the Company. Under the agreement, Aesgen will
pay license fees and additional royalties upon marketing the product, although
there can be no assurance that the product will be approved by the FDA or
marketed. AAI continues to hold a $1.6 million non-voting, non-convertible
preferred stock investment in Aesgen.

     In addition to its development work for Endeavor and Aesgen, the Company
has continued its internal development of products to be licensed to third
parties that have marketing and distribution capabilities. The Company has
entered into numerous license agreements for products that are currently in
development. The terms of the license agreements vary as to amounts of milestone
payments, as well as methods and extent of revenue participation. While the
Company anticipates that most of its product license agreements will provide
that prospective clients will ultimately sponsor the approved product, in
certain instances the Company has made submissions for internally developed
products in its own name.

     Continuing to leverage its development capabilities, the Company has moved
into product line extension development and has also begun reviewing new
compounds that are chemically similar to currently marketed products with proven
therapeutic and safety profiles, and that offer improved characteristics over
the marketed product. Such improved characteristics would include enhanced or
new therapeutic indices, reduced side effects, improved bioavailability and
improved pharmacokinetics. Because considerable toxicity data already exists for
the marketed product, the Company believes that product lines extensions and
pro-drugs generally could be developed with less risk of failure and in a
shorter time frame than new chemical entity development. The Company believes
that virtual and limited-resource drug companies provide opportunities to enter
into collaborative ventures to identify and develop these types of compounds.

     The Company is also active in providing product life cycle management for
major existing products. The Company brings together scientific, patent and
regulatory capabilities focused on enhancing existing products.

TECHNOLOGY DEVELOPMENT PROGRAM

     As an adjunct to the internal development program, the Company has sought
to protect certain intellectual property it has developed relative to the drug
development process. The Company has established a patent committee that meets
regularly to review employee-generated submissions of possible patentable
subject matter. The patent committee reviews the novelty and usefulness of the
submission and, with input from the marketing department as to commercial
viability, determines to either pursue a patent application or designate the
submission as a trade secret.

     The Company's internal development program has yielded multiple issued
patents and has several pending applications. For example, the Company's
patented Pro-Sorb(R) formulation technology has been shown to facilitate the
oral absorption of a number of non-steroidal anti-inflammatory drugs or NSAIDs,
such as diclofenac, to reduce gastric irritation and speed the onset of
therapeutic activity. In addition, the Company has patented a novel oral
delivery system for certain biotechnology compounds that may currently be
administered only by injection. The Company is seeking licensing partners for
its other recently developed technologies.

FEE-FOR-SERVICE BUSINESS

     The Company also provides a broad array of drug development services,
including chemical analysis, synthesis and other laboratory services;
formulation development; bioanalytical services; clinical supply and niche
manufacturing; clinical trial services and monitoring; and regulatory and
compliance consulting. The Company assigns project management teams consisting
of customer service representatives and technical

                                        3
<PAGE>   5

employees that meet with clients at frequent intervals to monitor and guide
projects through the development process. Continual client interaction allows
the Company to efficiently manage the drug development process. Historically,
the Company's laboratory services have accounted for approximately one half of
its fee-for-service revenue, although relative amounts vary from year to year.
Formulation development projects and clinical supply and niche manufacturing
generally have contributed the major portions of remaining annual
fee-for-service revenue.

LABORATORY SERVICES

     In support of its own internal as well of its clients' drug development and
compliance programs, the Company offers laboratory services to characterize and
measure drug components and impurities. The Company has more than 19 years
experience in providing analytical testing services dedicated exclusively to the
drug industry and has developed the scientific expertise, state-of-the-art
equipment and broad range of scientific methods to accurately and quickly
analyze almost any compound or product. The Company's laboratory services
include method development and validation; stability studies; raw materials and
release testing; biotechnology, microbiology and bioanalytical testing; product
characterization and organic synthesis.

     Method Development and Validation.  The Company develops and validates
methods used in a broad range of laboratory testing necessary to determine
physical or chemical characteristics of compounds. Analytical methods are
developed to demonstrate potency, purity, stability or physical attributes.
These methods are validated to ensure the data generated by these methods are
accurate, precise, reproducible and reliable and are used throughout the drug
development process and in product support testing.

     Stability Studies.  The Company provides stability testing and secure
storage facilities necessary to establish and confirm product purity, potency
and other shelf-life characteristics. Stability testing is required at all
phases of product development, from dosage form development through commercial
production, to confirm shelf life of each manufactured batch. The Company
maintains state-of-the-art climate-controlled facilities in the United States
and Germany to determine the impact of a range of storage conditions on product
integrity. FDA regulations and the regulations of European regulatory
authorities require that samples of clinical and commercial products placed in
stability chambers be analyzed in a timely fashion after scheduled "pull points"
occur, based on the date of manufacture. The Company's proprietary Laboratory
Tracking System (LTS) tracks client products maintained at the Company's
stability storage facilities and automatically schedules required testing as
pull points occur.

     Raw Materials and Product Release Testing.  The Company offers testing
required by the FDA and other regulatory agencies to confirm that raw materials
used in production and resulting finished products are consistent with
established specifications. Due to the incorporation of "just in time" inventory
control systems in client production schedules, release testing for both raw
materials and the finished product often cannot be scheduled by clients in
advance, yet must be performed immediately. The Company believes that its
internal scheduling systems, analytical laboratory expertise and systems for
prompt testing provide it with a competitive advantage in providing both raw
material and batch release testing. The Company believes that this service
enhances its client's confidence in adopting cost-saving "just in time"
inventory control systems.

     Biotechnology Analysis and Synthesis.  Although the types of analytical
investigations of biotechnology products are similar to those required for more
traditional pharmaceutical products, the complex molecular structure of many
biotechnology products requires different technology and expertise. The Company
provides a broad array of biotechnology services, including both analytical and
biological testing and method development and validation. AAI's breadth of
services allows the Company to rapidly deduce and characterize the complex
structure of the biotechnology product and measure the molecule or its
metabolites in human blood plasma to support clinical trial evaluation. The
Company has expertise in a broad spectrum of biochemical and immunochemical
methods for characterization and analysis of biotechnology drugs. These methods
include amino acid sequencing, amino acid analysis, peptide mapping,
carbohydrate and lipid analysis and electrophoresis. The Company also has
expertise in developing chromatographic methods that precisely evaluate the
purity and stability of biotechnology products. This service breadth and
diversity of analytical skills and technologies enable the Company to assist its
clients from early product development

                                        4
<PAGE>   6

through the investigational new drug application and product license application
stages and commercial production.

     Microbiological Testing.  Microbiological testing is an essential indicator
to ensure that a drug product, whether raw material or finished product, does
not contain harmful micro-organisms. The Company has significant experience
conducting various microbial tests to identify and quantify micro-organisms that
may be present, including limulus amebocyte lysate testing, which measures toxic
byproducts of micro-organisms, and particulate matter testing to determine the
presence of foreign matter in injectable drug products. The Company also
performs sterility testing to identify the genus and species of any
micro-organisms that are present. In addition, the Company performs tests to
determine the effectiveness of antibiotics against micro-organisms and the
minimum levels of preservatives necessary in product formulations. The Company
also assists clients with environmental monitoring, including water and air
systems testing, using an automated biochemical system to identify
micro-organisms present and determine whether such systems are within applicable
microbial limits. The Company assists clients in validating their environmental
control systems to ensure compliance with Good Manufacturing Practices (GMP)
regulations.

     Bioanalytical Testing.  The Company offers bioanalytical testing services
to support clinical trials for its and its clients' pharmaceutical product
development needs, analyzing plasma samples to characterize the metabolized
forms of the drug and determine the rate of absorption. Bioanalytical studies of
new drugs often present challenging and complex issues, with products being
metabolized into multiple active and inactive forms, each of which must be
measured. The Company works with its clients to develop and validate analytical
methods to permit detection and measurement of the various components to trace
levels. The acquisition of L.A.B. in 1996 and KCAS in 1998 significantly
enhanced the Company's bioanalytical capabilities.

     Product Characterization.  The Company has the expertise and instruments
required to identify and characterize a broad range of chemical entities.
Characterization analysis identifies the chemical composition, structure and
physical properties of a compound, and characterization data forms a significant
portion of a regulatory application. The Company uses numerous techniques to
characterize a compound, including spectroscopy, chromatographic analyses and
other physical chemistry techniques. Additionally, the Company uses such
information for control testing to be performed throughout development and
marketing to confirm consistent drug composition. Once appropriate test methods
are developed and validated, and appropriate reference standards are
characterized and certified, the Company can assist clients by routinely testing
compounds for clinical and commercial use.

     Organic Synthesis.  The Company develops synthesis methods for producing
experimental quantities of new compounds needed for analytical characterization,
toxicological studies, formulation development and clinical trials. Through
organic synthesis techniques, the Company can produce reference standards of the
active compound, specific impurities, degradation by-products, bioassay
reference standards or molecular analogs to permit sufficient quantities of such
compounds to be separately characterized and studied.

FORMULATION DEVELOPMENT SERVICES

     The Company provides integrated formulation development services for its
own internally developed pharmaceutical products and for those of its clients,
enabling the Company to take a compound and develop a safe and stable product
with desired characteristics. The Company believes its formulation expertise and
extensive analytical capabilities enable it to provide an efficient, seamless
development program, with a dedicated project team tracking the product through
all stages of formulation development. The Company provides formulation
development services during each phase of the drug development process, from new
compounds and modifications of existing products to generic versions of branded
products. The Company's formulation development projects may support a small
segment of critical development activities or may last for several years going
from early formulation development to optimized and validated production-scale,
packaged product.

     The Company's formulation development expertise spans a broad spectrum of
therapeutic areas. The Company works with clients and its own product
development personnel to develop products with desired
                                        5
<PAGE>   7

characteristics, including dosage form, strength, release rate, absorption
properties, stability and appearance. The Company has developed significant
product and process capabilities that enable it to efficiently solve the complex
problems that arise in developing formulations with targeted characteristics and
has developed a range of proprietary product technologies that allow it to
efficiently achieve desired results in product design and development.

     In providing formulation services, the Company works closely with clients
and its own product development personnel to design and conduct feasibility
studies to chart the potential of formulating a drug using a combination of
active drug ingredients and inert materials called excipients. Using
experimental designs, initial prototype formulations are prepared to identify
potential problems in stability, bioavailability and manufacturing. Generally,
formulation development is an iterative process, with numerous initial
formulations being modified as problems are encountered. The Company believes
its experience and expertise in formulation development, as well as certain
proprietary technologies, permit it to design efficient protocols for
identifying and optimizing prototypes with the greatest potential. Upon
selection of the final product prototypes, the Company develops protocols to
scale the product batch size from development stage (hundreds to thousands of
units) to clinical scale (thousands to millions of units). During the clinical
phase the Company refines the formulation in response to clinical, bioanalytical
and stability data. The manufacturing scale-up process involves identifying and
resolving manufacturing problems to facilitate an efficient transfer to the
full-scale production equipment of the Company's clients. Throughout the
development process, the Company develops and validates the analytical methods
necessary to test the product to establish and confirm product specifications.

     In addition to new drug development, the Company offers product
modification and line extension services to clients, generally for marketed
products facing patent expiration. Modifications of existing products offer the
Company's clients an opportunity to improve product characteristics, increasing
product market viability. Improved product characteristics include enhancement
of stability, absorption profiles (e.g., quick or sustained release), taste and
appearance. Product line extensions may include new dosage forms such as solids,
liquids and chewables, as well as new dosage strengths. Product modifications
and line extensions offer clients the opportunity to target new patient
subpopulations and improve patient compliance. The Company also offers
formulation services and other pharmaceutical product development services to
clients seeking to develop generic products.

CLINICAL SUPPLY AND NICHE MANUFACTURING

     The Company provides clinical trials materials for Phase I through IV
clinical trials. The Company has expertise in manufacturing tablets, capsules,
sachets, liquids and suspensions, creams, gels, lotions and ointments. The
Company believes that outsourcing of clinical supply manufacturing is
particularly attractive to pharmaceutical companies that maintain large,
commercial-quantity, batch facilities, where clinical supply manufacturing would
divert resources from revenue-producing manufacturing. Similarly, pharmaceutical
companies often seek to outsource commercial manufacturing of small quantity
products. The Company has a dedicated 20,000 square foot facility in Wilmington,
North Carolina and a similar facility in Paris, France to distribute and track
clinical trial materials used in clinical studies. In addition, the Company
provides its clients assistance in scaling up production of clinical supply
quantities to commercial quantity manufacturing, and manufactures inventory on
behalf of clients for commercial sale while client production facilities are
being built and validated.

     The Company's manufacturing facilities and equipment are qualified and
validated to operate under GMP regulations.

REGULATORY SERVICES

     The Company assists in the preparation of regulatory submissions, audits a
client's vendors and client operations, conducts seminars, provides training
courses, and advises clients on applicable regulatory requirements. The Company
also assists clients in designing development programs for new or existing drugs
intended to be marketed in the United States and Europe. At the client's
request, the Company will either

                                        6
<PAGE>   8

review client prepared submissions or draft sections and assemble regulatory
packages and attend FDA meetings with clients. The Company assists clients in
preparation for FDA inspections and assists them in correcting any deficiencies
noted in FDA inspections. In preparation for an FDA inspection, the Company's
regulatory affairs specialists conduct mock inspections to anticipate FDA
observations and advise clients of appropriate remedial actions. The Company
also audits manufacturers of active and excipient ingredients used in the drug
product, as well as packaging components, on behalf of clients to ensure that
the manufacturers' facilities are in compliance with GMP regulations. Such
audits generally include review of the vendor's drug master files, analysis of
written standard operating procedures ("SOP"), review of production records, and
observation of operations to ensure that written SOP's are being followed. Audit
reports include recommendations to address any deficiencies. The Company also
advises clients on validation issues concerning their systems and processes and
audits client facilities to assist them in validating their processes, cleaning,
water and air handling systems. The Company leverages its in-house laboratory
training programs by providing training to clients' employees. In addition, the
Company organizes and conducts seminars worldwide on a number of topical
industry issues.

CLINICAL SERVICES

     The Company has a 48-bed Phase I clinical trial facility located in the
same facility as one of the Company's analytical laboratories in Research
Triangle Park, North Carolina. With the acquisitions of L.A.B. and MTRA, the
Company expanded its Phase I clinical trial capabilities and added the ability
to conduct and monitor Phase II-IV studies and multi-center trials focused in
niche therapeutic areas, including hepatic disease, chemotherapeutics and
hormone replacement therapy. The Company's Neu-Ulm, Germany operations include a
57-bed facility for conducting certain Phase I and II clinical trial studies, as
well as bioequivalency studies.

     MTRA provides a full range of Phase II-IV clinical services to customers in
the pharmaceutical, biotechnology and medical device industries for assistance
in the drug development and regulatory approval process in North America as well
as to the Company's internal product development activities. The clinical
services include clinical trial management and monitoring, data management and
statistics. With the addition of MTRA in 1999, the Company anticipates that
clinical services will contribute more significantly to total revenues as
clinical services will be offered on a global scale and have a significant
customer base in the United States.

INFORMATION TECHNOLOGY

     The Company has made significant investments in information technology. The
Company's proprietary LTS system tracks laboratory workflow and enables the
Company to monitor and plan work through the Company's laboratories. The LTS
system monitors the progress of a client's project, records time expended by
laboratory personnel, tracks sample locations and controls document revisions.
The Company's customized data management system connects analytical instruments
with multiple software architectures permitting automated data capture. The
Company believes that information technology will enable it to expedite the
development process by designing innovative services for individual client
needs, providing project execution, monitoring and control capabilities that
exceed a client's internal capabilities, streamlining and enhancing data
presentation to the FDA and enhancing its own internal operational productivity
while maintaining its quality.

     In 1999, the Company continued its implementation of an enterprise wide
financial and operational integrated management information system including
significant systems licensed from SAP. Certain financial components became
operational at year end 1998, other operational management systems followed
later in 1999. The new system will eventually be implemented in all subsidiaries
and allows for expansion in a consistent and controlled manner.

CLIENTS

     The Company has provided services to most of the major pharmaceutical
companies in the world. The Company believes that concentration of business
among certain large clients is not uncommon in its industry. The Company has
experienced such concentration in the past and may experience such concentration
in the future. Although AAI strives to reduce its reliance on a limited number
of major clients, there can be no assurance that the Company's business will not
be dependent upon certain major clients, the loss of which could have a material
adverse effect on the Company. In addition, due to the project nature of the
Company's business, there can be no assurance that significant clients in any
one period will continue to be significant clients in other periods.

MARKETING AND BUSINESS DEVELOPMENT

     Since its inception, the Company has taken a customer-focused approach in
marketing its services, often placing the Company's technical personnel with its
clients' development teams to participate in planning meetings for the
development of a product. The Company assigns sales and technical personnel as
contacts for its larger clients, understanding that technical personnel may be
better able to identify the full scope of the client's needs and suggest
innovative approaches before the client formally develops the parameters of an
anticipated project. Generally, the Company also hosts more than ten technical
seminars per year for the pharmaceutical and biotechnology industries addressing
a variety of formulation development issues, stability testing and other topics.

CONTRACTUAL ARRANGEMENTS

     The Company's product development contracts typically provide for upfront
fees, milestone payments and royalties. The commercialization of the product is
the responsibility of the marketing partner. The Company's fee-for-service
contracts are typically evidenced by signed service estimates establishing an
estimated fee for identified services. During the Company's performance of a
project, clients often adjust the scope of services to be provided by the
Company in light of interim project results, at which time the amount of fees is
adjusted accordingly. Generally, the Company's fee-for-service contracts are
terminable by the client upon notice of 30 days or less, although certain major
formulation development and manufacturing agreements are not unilaterally
terminable by the client. Although the contracts typically permit payment of
certain fees for winding down a project, the loss of a large contract or the
loss of multiple contracts could adversely affect the Company's future revenue
and profitability. Contracts may be terminated for a variety of reasons,
including the client's decision to forego a particular study, the failure of
product prototypes to satisfy safety requirements and unexpected or undesired
results of product testing.

BACKLOG

     Backlog consists of anticipated net sales from signed service estimates and
other fee-for-service contracts that have not been completed and provide for a
readily ascertainable price. Once contracted work begins, net sales are
recognized as the service is performed. In certain cases, the Company begins
work for a client before a contract is signed. Accordingly, backlog does not
include anticipated net sales for which the Company has begun work but for which
the Company does not have a signed service estimate, or for any variable-priced
contracts. In addition, during the course of a project the client may
substantially adjust the requested scope of services and corresponding
adjustments are made to the price of services under the contract.

     The Company believes that its backlog as of any date is not a meaningful
predictor of future results because the backlog can be affected by a number of
factors, including variable size and duration of contracts and adjustments in
the scope of a contracted project as interim results become available.
Additionally, contracts generally are subject to termination by clients upon 30
days notice or less. Moreover, the scope of a contract can change over the
course of a project. At December 31, 1999 and 1998 backlog was approximately
$75.2 and $45.0 million, respectively. Of the 1999 amount, approximately $36.9
million is not expected to be filled within year 2000.

COMPETITION

     The Company competes primarily with in-house research, development, quality
control and other support service departments of pharmaceutical and
biotechnology companies, as well as university research laboratories. In
addition, the Company believes that although there are numerous competitors in
its industry, there are few competitors that offer the depth and breadth of
scientific capabilities that it provides. Certain of the Company's competitors
may have significantly greater resources than the Company. Competitive
conditions for service areas vary.

     Competitive factors include reliability, turn-around time, reputation for
innovative and quality science, capacity to perform numerous required services,
financial viability and price. The Company believes that it competes favorably
in these areas.

GOVERNMENT REGULATION

     The services performed by the Company are subject to various regulatory
requirements designed to ensure the quality and integrity of pharmaceutical
products, primarily under the Federal Food, Drug, and Cosmetic Act and
associated GMP regulations which are administered by the United States Food and
Drug Administration (FDA) in accordance with current industry standards.
Services being performed outside the United States or for products intended to
be substituted to non-U.S. jurisdictions may be subject to additional regulatory
requirements and government agencies applicable to that jurisdiction. U.S.
regulations apply to all phases of drug manufacture, testing and record keeping,
including personnel, facilities, equipment, control of materials, processes and
laboratories, packaging, labeling and distribution. Noncompliance with such
regulations by the Company in a project could result in disqualification of data
collected by the Company for such project. Material violation of regulatory
requirements could result in additional regulatory sanctions. In severe cases
violations could result in a mandated closing of the Company's facilities which
would materially and adversely affect the Company's business.

     To help assure compliance with applicable regulations, the Company has
established quality assurance controls at its facilities that monitor ongoing
compliance by auditing test data and regularly inspecting facilities, procedures
and other regulatory compliance parameters. In addition, FDA regulations and
guidelines, as well as applicable international standards, serve as a basis for
the Company's standard operating procedures. Certain of the Company's
development and testing activities are subject to the Controlled Substances Act,
administered by the Drug Enforcement Agency (the "DEA"), which regulates
strictly all narcotic and habit-forming substances. The Company maintains
separate, restricted-access facilities and heightened control procedures for
projects involving such substances due to the level of security and other
controls required by the DEA.

     The Company's activities involve the controlled use of hazardous materials
and chemicals. The Company is subject to federal, state and local laws and
regulations governing the use, storage, handling and disposal of such materials
and certain waste products and is insured against losses arising out of the
normal course of business operations. Although the Company believes that its
safety procedures for handling and disposing of such materials comply with the
standards prescribed by federal, state and local laws and regulations, the risk
of accidental contamination or injury from these materials cannot be completely
eliminated. In the event of such an accident, the Company could be held liable
for any damages that result which could materially and adversely affect the
financial condition of the Company.

EMPLOYEES

     At December 31, 1999, the Company had approximately 1,100 full-time
equivalent employees, of which 73 hold Ph.D. or M.D. degrees, or the foreign
equivalent. The Company believes that its relations with its employees are good.
None of the Company's employees in the U.S. are represented by a union. German
and French law provide certain representative rights to employees.

     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

                                        9
<PAGE>   11

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. While the Company has not experienced any
significant problems in attracting or retaining qualified staff, there can be no
assurance that the Company will be able to avoid these problems in the future.

     All employees enter into confidentiality agreements protecting the
Company's proprietary information, as well as client-confidential material. New
U.S.-based employees are generally required to sign non-competition agreements,
prohibiting the employee from engaging in activities in competition with the
Company for a period of one year after termination of employment.

ITEM 2.  PROPERTIES.

     The Company's principal executive offices are located in Wilmington, North
Carolina, in a 74,000-square foot leased facility. The Company's primary U.S.
facilities are located in Wilmington, North Carolina; Research Triangle Park,
North Carolina; North Brunswick, New Jersey; Natick, Massachusetts; and Shawnee,
Kansas constituting approximately 278,000 square feet of total operational and
administrative space. The Company's primary European facilities are located in
Neu-Ulm, Germany and include approximately 120,000 square feet of operational
and administrative space. This facility is leased under renewable leases
expiring in 2008. The Company maintains other operating units at leased
facilities in San Bruno, California; Toronto, Canada; Munich, Germany; Paris,
France; and Arnhem, Netherlands. The Company maintains sales offices in Chicago,
Illinois; Boston, Massachusetts; San Diego and San Francisco, California;
Copenhagen, Denmark; London, England; Rome, Italy and Tokyo, Japan. The Company
also has joint operations with Shanghai Second Medical University located in
Shanghai, China and Tonji University in Wuhan, China. The Company believes that
its facilities are adequate for the Company's operations and that suitable
additional space will be available when needed.

ITEM 3.  LEGAL PROCEEDINGS.

     The Company may be party to lawsuits and administrative proceedings
incidental to the normal course of its business which are not considered
material. Management does not believe that any liabilities related to such
lawsuits or proceedings will have a material adverse effect on the Company's
financial condition, results of operations or cash flows.

     On July 28, 1999, AAI filed a demand for arbitration against a former
client seeking approximately $700,000 for manufacturing services rendered. The
former client counterclaimed for $5 million alleging various misrepresentations
by the Company. On December 29, 1999, the former client filed suit in North
Carolina State Court contesting the arbitration and seeking several million
dollars in alleged damages. The Company countersued the former client for
approximately $3.6 million, including interest, for various services rendered in
addition to the amounts owed for manufacturing services. The State Court ruled
in February that all claims under the manufacturing agreement are to be decided
under arbitration. A June 2000 date has been set for the arbitration. Discovery
has not yet commenced in the litigation. The Company and the former client are
attempting to negotiate a settlement in lieu of the arbitration and legal
proceedings, however, there can be no assurance that any settlement will occur.
The Company vigorously contests the claims made by this former customer and
believes it is entitled to the value of the services rendered. The Company does
not believe that any future settlement will have a material adverse effect on
the Company's financial condition, results of operations or cash flows.

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

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

OVERVIEW

     The Company is engaged in the business of performing product development
and support services on a contract basis for large and small pharmaceutical
companies around the world as well as the development of select generic drugs
and improved formulations of marketed drugs. In implementing this strategy, the
Company earns revenue through fee-for-service contracts with customers and by
licensing and selling internally developed technologies and products.

     The product development business utilizes the resources and operating
capacity of the nonclinical and clinical groups to study and develop new and
improved drugs and drug technologies that improve existing drugs. The Company
licenses the developed technologies and products to customers usually before the
development is complete. In general, the Company is partially paid for its
efforts and innovations at predefined events, known as milestones, which are
intended to help cover the costs of development. The milestone payments are not
refundable. In most cases, the Company also receives royalties on the eventual
sales of the approved product. The Company bears the risk that some of the
development projects may not be approved or that the eventual sales of the
product may not meet expectations. These development projects generally last
several years.

     The fee-for service business consists of two main groups, a nonclinical and
a clinical group. The nonclinical group performs laboratory analysis of various
chemical compounds and small scale manufacturing of chemical compounds used for
further testing, or in some cases, for sale to the public. The services
performed by the nonclinical group include chemical analysis, chemical
synthesis, drug formulation, clinical supply and niche manufacturing,
bio-analytical studies, and regulatory and compliance consulting. All of these
services involve either laboratory work or consulting services. The clinical
group performs testing of new drugs for customers and the Company's own
pharmaceutical development program under controlled conditions as part of the
customers' process in gaining approval for the drug. All of the clinical
services involve contact with patients and monitoring clinical studies performed
in hospitals and clinics.

     Both the nonclinical and clinical groups receive requests for services from
a customer, often on a competitive basis. An estimate of costs to perform the
service is delivered to the customer based on the expected resources and
materials required to complete the project. The projects vary in length, some
lasting less than one month and others lasting several years, however, most
projects may be cancelled by the customer with 30 days notice.

     This Annual Report contains certain forward-looking statements within the
meaning of Section 27A of the Securities Act of 1933 and Section 21E of the
Securities Exchange Act of 1934. These statements involve risks and
uncertainties that may cause actual results to differ materially, including,
without limitation, the ability to successfully complete scheduled product
development projects, continue historic success in entering into beneficial
royalty agreements with pharmaceutical companies, obtain timely regulatory
approvals of the Company's internally developed products, dependence on third
party marketing and distribution of internally developed products, the ability
of acquired businesses to be integrated with AAI's operations, actual
operational performance, the ability to hire and retain qualified employees,
other regulatory approvals and industry outsourcing trends.

RESULTS OF OPERATIONS

     On March 16, 1999, the Company merged with Medical & Technical Research
Associates, Inc., (MTRA) a clinical research organization located near Boston,
Massachusetts. MTRA offers clinical phase II -- IV studies predominately in the
US market to large and small pharmaceutical companies. The addition of MTRA adds
clinical phase II -- IV capabilities in the United States and will significantly
increase AAI's ability to provide clinical testing to U.S. customers and enable
the Company to compete for global clinical trial engagements.

     The MTRA merger was accounted for as a pooling-of-interests, and
accordingly, all prior period consolidated financial statements have been
restated to include the results of operations, financial position, and
                                       14
<PAGE>   16

cash flows of MTRA as though MTRA had always been a part of AAI. Results for the
years ended December 31, 1999, 1998 and 1997 represent the combined results of
AAI and MTRA.

  1999 Compared to 1998

     Net revenues increased by 4% in 1999 compared to 1998. Increases were
achieved in both segments, with fee-for-service revenues up by 1% and product
development revenues higher by 39%. The fee-for service increase was due to the
inclusion of KCAS for an entire year, as opposed to a partial one for 1998.
Excluding KCAS, fee-for-service revenues were down 3%, reflecting capacity
underutilization in the second and third quarters as a result of industry-wide
volume decreases. The significant increase in product development revenues
represents the early benefits of the Company's substantial research and
development spending in 1999 and prior years.

     Overall, gross margins as a percentage of revenues decreased by 4% to 44%.
Fee-for-service margins decreased by 6%, again due to capacity underutilization
in the second and third quarters. This impact has been somewhat offset at the
gross margin level due to the higher mix of product development revenues, with
related expenses recorded as research and development.

     Selling expenses increased by 22% over last year. In addition, selling
expenses increased as a percentage of revenues from 10% to 12%. These increases
reflect the expansion of the Company's sales and marketing infrastructure.
General and administrative expenses increased by 16% in 1999, due primarily to a
special charge taken in the fourth quarter of $2.2 million for reserves on
certain customer balances, as well as the addition of several senior personnel
to the Company's management team. Management believes that while dollar levels
of selling and administrative spending will increase, the level of spending as a
percentage of revenues will decline in future years.

     Research and development expenses increased by 68% and as a percentage of
revenues, from 6% to 10%. The substantial R&D spend is consistent with the
Company's strategy of long-term product development.

     In connection with the March 1999 merger with MTRA, the Company recorded a
$6.4 million nonrecurring charge to operating income reflecting the costs to
complete the transaction, integrate the businesses and realign its workforce to
its new combined operating structure. See Note 2 in Item 8 "Financial Statements
and Supplementary Data" for more information.

     Income from operations decreased from income of $9.6 million in 1998 to a
loss of $8.8 million in 1999. The first factor in this change was a decrease in
the fee-for-service margins by 6%, resulting from capacity underutilization in
the second and third quarters. Second was the significant increase in 1999
research and development spending of $4.2 million higher then 1998, supporting
the Company's strategy of long-term product development. A third factor was the
$2.2 million special charge for reserves on certain customer balances, causing a
considerable increase in general and administrative expenses. A last factor was
the $6.4 million nonrecurring charge for restructuring costs in connection with
the MTRA merger.

     The swing from interest income in 1998 to interest expense in 1999 is
explained below in "Liquidity and Capital Resources". Generally, the Company
moved from a cash investor to a borrower in 1999 as a result of restructuring
cost payments and purchases of property and equipment.

     The Company's benefit for income taxes was $2.3 million in 1999 as compared
to a provision of $3.6 million in 1998 in accordance with the pretax loss or
income. The effective tax benefit rate in 1999 was 22.3% compared to an
effective tax rate of 35.2% in 1998. This decrease in the effective rate is
primarily the result of a $1.3 million increase in net permanent differences in
1999.

     The 1999 income tax benefit reflects the Company's utilization of
accumulated U.S. net operating losses as a carryback credit against income taxes
previously paid in 1998 and 1997. To date, the Company has not recognized an
income tax benefit related to net operating loss carryforwards because the
Company incurred operating losses in 1999 and the realization of future tax
benefits is uncertain. However, as the Company generates additional taxable
income to the extent of the cumulative losses, a tax benefit for losses incurred
will be recognized by utilizing net operating loss carryforwards.

  1998 Compared to 1997

     Net revenues increased by 23% in 1998 compared to 1997. The increase was
due in part to the acquisition of KCAS, without which the revenue increase would
have been 20%. Fee-for-service revenues increased 22% while product development
revenues increased 26% in 1998 over 1997.

     Gross margins in the fee-for-service business increased to 44% from 43%,
with no change in the percentage after excluding KCAS.

     Selling expenses increased by 4% but decreased as a percentage of sales
from 12% to 10% in 1998 from 1997 levels. General and administrative expenses
increased by 17% in 1998, but decreased as a percentage of fee for service
revenues to 24% in 1998 from 25% in 1997. The increase was due mainly to
increases in staff costs which supported the higher volumes and revenues. Both
selling and general and administrative expenses decreased as a percentage of
fee-for-service revenues in 1998 from 1997 levels.

     Research and development expenses decreased by 21% in 1998 from 1997
levels. Overall research spending as a percent of net revenues also decreased
from 10% in 1997 to 6% in 1998. The decrease was due partially to the stage of
development of the internal products. In addition, this decrease was partially
due to the Company internally performing various research activities which had
previously been sent to outside parties. The Company was able to perform these
research activities internally as a result of its acquisitions of L.A.B., KCAS
and through internal expansion.

     The Company terminated certain business combination discussions during the
third quarter of 1997. In relation to these discussions, the Company recognized
a net credit of $400,000 in other income, representing a $1 million payment made
to its German subsidiary and approximately $600,000 of expenses incurred by AAI.

     Income from operations had a significant increase of $8.1 million in 1998
over 1997. The major portion of this increase came from the fee-for-service
segment of the business, which increased revenues by $16.1 million, or 22%. The
product development segment of the business also contributed to the increase,
with $1.5 million of higher revenues coupled with lower research and development
spending of $1.7 million. These increases were somewhat offset by higher
selling, general and administrative expenses as discussed above.

     The Company's provision for income taxes was $3.6 million in 1998 compared
to $342,000 in 1997. The increase in the Company's tax provision from 1997 to
1998 resulted mainly from applying the federal statutory rates to the $7.2
million increase in pretax income.

LIQUIDITY AND CAPITAL RESOURCES

     The Company has funded its business primarily through cash flows from
operations and borrowings. In 1999, $12.7 million of cash was used in
operations, $5.7 million of which were restructuring payments. In addition,
purchases of property and equipment amounted to $13.5 million. Major capital
assets purchased during 1999 included the establishment of a new corporate
facility in Wilmington, North Carolina and continued implementation of an
enterprise wide financial and operational integrated management information
system. These uses of cash were funded through net financing activities of about
$16.2 million.

     In 1998, $2.7 million of cash was generated from operations. Cash was used
in 1998 as follows: $4.0 million to acquire KCAS; $14.6 million to purchase
capital assets; and a $8.8 million increase in noncash working capital. The
major capital assets purchased in 1998 include a clinical supply manufacturing
and distribution facility in Wilmington, North Carolina, and the opening of an
analytical facility in North Brunswick, New Jersey.

     In 1997, $13.4 million of cash was used by operations predominately to
increase noncash working capital and $4.4 million was received through
additional borrowings. Cash was used to purchase capital assets in the amount of
$11.4 million.

     Capital assets purchased were for new equipment and facility improvements
to increase capacity and productivity. The Company anticipates capital
expenditures in 2000 to be significantly below the 1999 level.

                                       16
<PAGE>   18

     Working capital was $6.5 million at December 31, 1999 and $26.2 million at
December 31, 1998. The Company has a $25 million credit facility available to
supplement its liquidity needs. Since this credit facility expires in May 2000,
the outstanding balance of $18.2 million at December 31, 1999 was classified as
current debt, thus reducing working capital. At the present time, the Company is
renegotiating its credit facility and expects either an extension or new
facility to be in place before the current facility expires.

     The Company expects to continue expanding its operations through internal
growth and strategic acquisitions. The Company expects such activities will be
funded from existing cash and cash equivalents, cash flow from operations and
borrowings under its credit facility. The Company believes that such sources of
cash will be sufficient to fund operations for the current and foreseeable
future and to pay existing debt as it becomes due and other capital obligations.
The Company is constantly evaluating acquisition or other growth opportunities.
At some point in the future there may be opportunities that require additional
external financing, and the Company may from time to time seek to obtain funds
from the public or private issuance of equity or debt securities. There can be
no assurances that such financing will be available on terms acceptable to the
Company.

YEAR 2000 DISCLOSURE

     The Company has assessed its computer systems for year 2000 readiness and
replaced all systems and software it found to be noncompliant. These
replacements were generally part of a regular upgrade program. In addition, the
Company tested all of its systems and software and has obtained verifications
from its vendors that the systems they supplied are year 2000 ready. The Company
believes that any year 2000 problem is unlikely to arise in the future, and that
if any problem does arise, it will be able to fix the problem quickly and
without material expenses.

     To date, the Company has not experienced any disruptions of operations due
to year 2000 problems, nor has it received notice from any of its customers
about problems resulting from non-year 2000 compliant software.

INFLATION

     The Company believes the effects of inflation generally do not have a
material adverse effect on its results of operations or financial condition.

EURO CONVERSION

     On January 1, 1999, the European Community began denominating significant
financial transactions in a new monetary unit, the Euro. The Euro is intended to
replace the traditional currencies of the individual EU member countries. The
Company's operations in Europe are continuing to operate in the traditional
currencies and are not converting internal financial systems to the Euro as a
functional currency. The Company's significant operations all have
multi-currency capable systems and will account for Euro denominated
transactions without additional modification or difficulty. The Company is
evaluating when to convert its local currency in Europe to the Euro with as
little disruption to customer and vendors as possible. The Company does not
intend to make such a conversion in 2000.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

     The Company, as a result of global operating activities, is exposed to
risks associated with changes in foreign exchange rates. As foreign exchange
rates change, the U.S. Dollar equivalent of revenues and expensed denominated in
foreign currencies change and can have an adverse impact on the Company's
operating results. To seek to minimize its risk from foreign exchange movement,
the Company uses local debt to fund its foreign operations. If foreign exchange
rates were to change 10%, operating results would have changed by $77,000 in
1999.

                                       17
<PAGE>   19

     The Company is also exposed to changes in interest rates on its variable
rate debt instruments. If interest rates were to change 1%, based on year end
debt amounts subject to variable interest rates, annual interest expense on
variable rate debt would change by $212,000.

                         REPORT OF INDEPENDENT AUDITORS

To the Board of Directors and Stockholders of
Applied Analytical Industries, Inc.

     We have audited the accompanying consolidated balance sheets of Applied
Analytical Industries, Inc. and subsidiaries as of December 31, 1999 and 1998,
and the related consolidated statements of operations, stockholders' equity and
cash flows for each of the three years in the period ended December 31, 1999.
Our audits also included the financial statement schedule listed in the Index at
Item 14(a). These financial statements and schedule are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements and schedule based on our audits. We did not audit the
financial statements of Medical & Technical Research Associates, Inc., a
wholly-owned subsidiary, for the year ended December 31, 1997 which statements
reflect total net revenues constituting 18 percent of the related consolidated
total. Those financial statements were audited by other auditors whose report
has been furnished to us, and our opinion, insofar as it relates to the amounts
included for Medical & Technical Research Associates, Inc. for 1997, is based
solely on the report of the other auditors.

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

     In our opinion, based on our audits and, for 1997, the report of other
auditors, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of Applied
Analytical Industries, Inc., and subsidiaries at December 31, 1999 and 1998, and
the consolidated 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. Also, in our
opinion, the related financial statement schedule, when considered in relation
to the basic financial statements taken as a whole, presents fairly in all
material respects the information set forth therein.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.  SIGNIFICANT ACCOUNTING POLICIES AND OTHER MATTERS

ORGANIZATION

     Applied Analytical Industries, Inc. ("AAI") is a multinational specialty
pharmaceutical company conducting its own internal product development and
providing pharmaceutical product development for large and small pharmaceutical
companies with its principal offices in the United States and Germany. The
majority of revenues are earned in the fee-for-service business as explained in
Note 10 and a portion of the Company's resources are devoted to research and
development of new products. Major customers are large and small pharmaceutical
and biotechnology companies.

BUSINESS COMBINATIONS

  Medical & Technical Research Associates, Inc.

     On March 16, 1999, the Company merged with Medical & Technical Research
Associates, Inc., (MTRA) a clinical research organization located near Boston,
Massachusetts, in exchange for approximately 1.3 million shares of AAI stock,
including conversion of MTRA stock options. The MTRA merger was accounted for as
a pooling-of-interests, and accordingly, all prior period consolidated financial
statements have been restated to include the results of operations, financial
position, and cash flows of MTRA as though MTRA had always been a part of AAI.
The results of operations for the separate companies and the combined amounts
presented in the financial statements are as follows:

  Kansas City Analytical Services, Inc.

     On September 14, 1998, the Company acquired all of the outstanding equity
of Kansas City Analytical Services, Inc. (KCAS), a bioanalytical and
pharmaceutical analysis laboratory located near Kansas City, Kansas. The
acquisition has been accounted for using the purchase method of accounting. The
aggregate purchase price was approximately $5.5 million, consisting of cash
($5.2 million) and the issuance of 26,642 shares of common stock. The excess of
the purchase price over the fair value of the assets acquired was $1.5 million
and has been recorded as goodwill which is being amortized on a straight line
basis over 20 years. Accordingly, the results of KCAS's operations have been
included in the Company's consolidated results from the date of acquisition.

BASIS OF PRESENTATION

     The consolidated financial statements include the accounts of Applied
Analytical Industries, Inc. and its wholly-owned subsidiaries ("The Company").
All material intercompany transactions have been eliminated. The Company has
ownership of approximately 35%, on a fully diluted basis, of Endeavor
Pharmaceuticals Inc. ("Endeavor") which is accounted for under the equity
method. Certain balances in the prior year consolidated financial statements
have been reclassified to conform to the December 31, 1999 presentation.

REVENUE RECOGNITION

     Revenues from fee-for-service contracts are recognized generally on a
percentage-of-completion basis as the work is performed. Licensing revenues are
recognized generally on a percentage-of-completion basis for interim contract
milestones. Contract milestones based on product approval are recognized when
the applicable product is approved. Royalty revenues are recognized as earned in
accordance with contract terms. Work-in-progress represents revenues recognized
prior to contract billing terms. Provisions for losses on contracts, if any, are
recognized when identified.

INCOME TAXES

     Income taxes have been provided using the liability method in accordance
with Financial Accounting Standards Board ("FASB") Statement of Financial
Accounting Standards ("SFAS") No. 109 "Accounting for Income Taxes". Deferred
tax assets and liabilities are recognized for the expected tax consequences of
temporary differences between the tax bases of assets and liabilities and their
reported amounts.

RESEARCH AND DEVELOPMENT COSTS

     Research and development costs related principally to product development
are charged to expense as incurred.

EARNINGS PER SHARE

     During 1999, the Company completed a business combination accounted for as
a pooling of interests and accordingly, all share and per share amounts have
been restated to reflect the business combination (see Note 2). Basic earnings
per share are based on the weighted average number of common shares outstanding
during the year. The weighted average number of common shares outstanding was
approximately 17,204,011, 17,123,503 and 17,091,573 in 1999, 1998 and 1997,
respectively. Diluted earnings per share were computed assuming that the
weighted average number of shares was increased by the conversion of stock
options issued to employees and members of the Company's Board of Directors. The
diluted per share amounts reflect a change in the number of shares outstanding
(the "denominator") to include the options as if they were converted to shares
and issued. In each year presented, the net income (the "numerator") is the same
for both basic and diluted per share computations. The following table provides
a reconciliation of the denominators for the basic and diluted earnings per
share computations for each of the years ended December 31:

WORK-IN-PROGRESS

     Work-in-progress represents revenues recognized for the value of work
completed prior to contracted billing dates.

PROPERTY AND EQUIPMENT

     Property and equipment is recorded at cost. Depreciation is recognized
using the straight-line method over the estimated useful lives of the assets.
Depreciable lives are 31.5 years for buildings and improvements and 3 to 15
years for equipment. Leasehold improvements are amortized over the lesser of the
asset life or the lease term. Depreciation expense was approximately $6.5
million, $4.6 million and $4.8 million for the years ended December 31, 1999,
1998 and 1997, respectively.

GOODWILL, INTANGIBLES AND OTHER ASSETS

     Goodwill, the excess of the purchase price over the fair value of the net
assets of acquired companies, is amortized over 20 years. At December 31, 1999
and 1998, the amounts for accumulated amortization of goodwill were
approximately $2.0 million and $1.3 million, respectively. Other identifiable
intangible assets are amortized, if applicable, on a straight-line basis over
their estimated useful lives, which range from 3 to 17 years. At December 31,
1999 and 1998, the amounts of accumulated amortization of other intangibles were
approximately $610,000 and $490,000, respectively.

     The Company has an investment in nonvoting, mandatorily redeemable
preferred stock of a related party, which is carried at original cost in other
assets.

     On an ongoing basis, the Company assesses the recoverability of its
goodwill, intangibles and other assets by determining its ability to generate
future cash flows sufficient to recover the unamortized balances over the
remaining useful lives. Goodwill, intangibles and other assets determined to be
unrecoverable based on future cash flows would be written-off in the period in
which such determination is made.

FOREIGN CURRENCY TRANSLATION

     The financial statements of foreign subsidiaries have been translated into
U.S. dollars in accordance with FASB Statement No. 52 "Foreign Currency
Translation". All balance sheet accounts have been translated using the exchange
rates in effect at the balance sheet date. Income statement amounts have been
translated using the average exchange rates for the year. The gains and losses
resulting from the changes in exchange rates from year to year have been
reported in other comprehensive income included in the stockholders' equity
statement.

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

     In June 1998, the FASB issued SFAS No. 133 "Accounting for Derivative and
Hedging Activities". SFAS No. 133, as amended, is required to be adopted in
years beginning after June 15, 2000. Because of the Company's minimal use of
derivatives, if any, management does not anticipate that the adoption of this
statement will have a material impact on net earnings or the financial position
of the Company.

EMPLOYEE STOCK BASED COMPENSATION

     The Company has elected to continue to follow APB Opinion No. 25,
"Accounting for Stock Issued to Employees" ("APB No. 25") and related
interpretations in accounting for its employee stock options as permitted by
SFAS No. 123 "Accounting for Stock-Based Compensation" and make the required pro
forma disclosures required by SFAS No. 123 (see Note 5). Under ABP No. 25, if
the exercise price of the Company's stock options is not less than the estimated
fair market value of the underlying stock on the date of grant, no compensation
expense is recognized.

FAIR VALUE OF FINANCIAL INSTRUMENTS

     The carrying value of cash and cash equivalents, accounts receivable, the
preferred stock investment, current liabilities and long-term debt approximate
fair value. It is not practicable to estimate the fair value of the Company's
equity investment, which is recorded at zero, as no readily determinable market
exists for investments in such entities.

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 amounts reported in the consolidated financial
statements and accompanying notes. Actual results could differ from such
estimates and changes in such estimates may affect amounts reported in future
periods.

2.  TRANSACTION, INTEGRATION AND RESTRUCTURING COSTS

     In connection with the MTRA merger, the Company recorded a $6.4 million
nonrecurring charge to operating income reflecting the costs to complete the
transaction, integrate the businesses and realign its workforce to its new
combined operating structure.

     Transaction costs were comprised of amounts owed to investment bankers and
advisors as a percentage of the total merger consideration and other expenses
directly related to the completion of the transaction, including financial
reviews and legal fees. Personnel costs include the separation of approximately
58 employees in the US and Europe to combine the clinical operations of the
companies and realign the workforce in the new organization. Facility and
equipment costs include lease payments required under noncancelable leases for
vacant properties and the write-off of leasehold improvements and equipment that
will become redundant or obsolete due to the transaction. Other costs include
integration costs directly related to the merger and other costs resulting from
actions taken to merge the operations.

     The industrial revenue bonds were secured to finance the acquisition and
construction of facilities in North Carolina. They have a variable interest
rate, which is adjusted annually with a maximum allowable rate of 15%. The rates
at December 31, 1999 and 1998 were approximately 5.5% and 4.2%, respectively.
The bonds are payable in monthly installments of $25,000, plus interest, through
November 2000, and are redeemable at the option of the bondholders. The Company
has entered into an agreement with a bank to pay any bonds redeemed under a
stand-by letter of credit covering the outstanding principal of the bonds. The
Company also has a bond re-marketing agreement with such bank to re-market any
bonds presented for early redemption, on a best efforts basis. These bonds have
been classified as short-term debt because of the early redemption feature.

     The bank term loans include approximately $1.7 million and $3.9 million
with U.S. banks as of December 31, 1999 and 1998, respectively. The loans have
variable interest rates based on the 30-day LIBOR. The loans are payable in
monthly installments including interest. The average interest rate on these
loans was approximately 6.9% for both 1999 and 1998. The bank term loans also
include approximately 8 million Deutsche marks, as of December 31, 1999 and
1998. This amount represents a subsidiary's note payable to a German bank, which
is due in March 2000 with interest payable quarterly at 4.85%. AAI has issued a
stand-by letter of credit to this bank to cover borrowings outstanding.

     In 1996, the Company entered into a revolving credit agreement with a U.S.
bank which, as amended, expires in May of 2000. The agreement provides for
borrowings of up to $25 million, based upon a borrowing base consisting of
portions of fixed assets and accounts receivable, at variable interest rates
based on the 30-day LIBOR. At the end of the revolving credit period, any
outstanding balances under this facility must be repaid. The agreement requires
the payment of certain commitment fees based on the unused portion of the line
of credit. At December 31, 1999, the Company qualified for the entire $25
million borrowing base of the facility; actual borrowings totaled $18.2 million.

     Under the terms of the revolving credit facility and the stand-by letter of
credit agreement, the Company is required to comply with various covenants
including, but not limited to, those pertaining to maintenance of certain
financial ratios, and incurring additional indebtedness. The company was in
compliance with these covenants at December 31, 1999.

     Scheduled maturities of long-term debt as of December 31, 1999 are
$4,854,000 -- 2000; $481,000 -- 2001; $481,000 -- 2002.

5.  STOCKHOLDERS' EQUITY

     The authorized capital stock of the Company at December 31, 1999 and 1998
was 100 million shares of voting common stock, $0.001 par value per share, and 5
million shares of preferred stock, $0.001 par value per share. The preferred
stock is issuable in one or more series by the Company's Board of Directors
without further stockholder approval. No preferred stock was outstanding at
December 31, 1999 or 1998. The Company has reserved 2,553,197 shares of common
stock for issuance under stock option plans.

STOCK OPTION AND AWARD PLANS

     The Company has four stock option plans, the 1997 Stock Option Plan ("1997
Plan"), the 1996 Stock Option Plan ("1996 Plan"), the 1995 Stock Option Plan
("1995 Plan") and the 1996 Incentive and Non-Qualified Stock Option Plan ("MTRA
Plan"). Under the 1995 Plan, the Board of Directors may grant options to
purchase up to 242,538 shares of common stock. However, the Company has no
obligation to issue the shares upon exercise of such options until it has
purchased an equal number of shares from certain existing stockholders. Under
the 1997 and 1996 Plans, the Board of Directors may grant options to purchase up
to 1,644,000 and 495,627, respectively, of newly issued shares of common stock.
AAI adopted the MTRA Plan in March 1999 after the MTRA merger (see Note 2).
AAI's board reserved 517,500 shares to cover the exercise of the options under
the MTRA Plan. The plans require that the exercise price of options cannot be
less than either 100% (1997 Plan and MTRA Plan) or 75% (1996 and 1995 Plans) of
the estimated fair market value of the Company's shares of common stock on the
date of grant.

     The combined activity from all plans is presented in the following table:

     The Company has adopted the disclosure-only provisions of SFAS No. 123. The

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     For purposes of pro forma disclosures, the estimated fair value of the
stock options are amortized to expense over the vesting period. The grant date
Black-Scholes weighted average fair value of options was $11.28, $6.87 and $7.84
per share for 1999, 1998 and 1997, respectively.

     The Company applies APB Opinion 25 and related interpretations in
accounting for its stock option plans; therefore, compensation expense has not
been recognized for all options granted. If compensation cost for the Company's
plans had been determined based on the fair value at the grant dates for awards
under those plans consistent with the method of FASB Statement 123, the
Company's net income (loss) and earnings (loss) per share would have been
changed to the pro forma amounts indicated below:

6.  RELATED PARTY TRANSACTIONS AND MAJOR CUSTOMERS

PHARMCOMM

     During 1999, the Company advanced $300,000 to PharmComm, Inc.
("PharmComm"), a company whose principal stockholders include Dr. Frederick
Sancilio, Mr. James Waters and Mr. William Underwood, all directors of AAI. One
other stockholder of PharmComm is a member of AAI management.

     The advance payment was for services to be rendered by PharmComm during
1999 and 2000 for scanning and indexing services required as part of AAI's
regulatory compliance and record retention policies. The services will be
performed by PharmComm after considering the timing of the advance payment. AAI
has engaged PharmComm to perform these services since 1996 and has compensated
PharmComm pursuant to written agreements for the services. PharmComm also
provides computer validation services to AAI, which are required for compliance
with regulatory requirements.

     Total payments for scanning and validation services provided to AAI by
PharmComm were approximately $214,000, and $436,000 for the years ended December
31, 1997, and 1998, respectively. In 1999, AAI paid PharmComm approximately
$277,000, excluding the advance payment for services discussed above. At
December 31, 1999, $249,000 of the $300,000 prepayment was remaining for
application to future invoices.

ENDEAVOR PHARMACEUTICALS INC.

     In 1994, AAI organized Endeavor Pharmaceuticals Inc. ("Endeavor") with
Berlex Laboratories, Inc. and several other investors to fund the development of
hormone pharmaceutical products, initially focusing on several generic hormone
products already under development by the Company. The Company has also agreed
to permit Endeavor, under certain circumstances, the first right to purchase
additional proprietary hormone pharmaceutical products developed by AAI. AAI
obtained a 47% equity interest in Endeavor through the contribution of its
accumulated product research and development and technical know-how. The other
investors contributed cash in exchange for their interests which, for all
investors, was in the form of convertible

                                       31

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

preferred stock. Based on a subsequent cash infusion by a new investor in 1995,
the Company's interest in Endeavor was reduced to approximately 35%, on a fully
diluted basis.

     This investment has been recorded at zero value since 1995. Endeavor has
accumulated losses of approximately $20 million as of December 31, 1999. The
Company will not be able to record any income from this investment until
Endeavor has earned income in an amount equal to such accumulated losses.

     The Company had net sales to Endeavor for product development services of
approximately $2.8 million, $1.6 million and $3.2 million for the years ended
December 31, 1999, 1998 and 1997, respectively. AAI had approximately $950,000
in accounts receivable at December 31, 1999 and approximately $1.6 million in
work-in-progress related to Endeavor at December 31, 1998.

     In December 1999, the Company agreed to purchase certain product rights and
validated manufacturing equipment from Endeavor. Endeavor assigned the rights to
an FDA approved hormone product and the related commercialization contract to
the Company. Under the commercialization agreement, the Company will be entitled
to certain minimum royalties upon the successful transfer of the manufacturing
process to the third party. Endeavor also sold a piece of manufacturing
equipment and related accessories to the Company. As consideration for the
product rights and equipment, the Company agreed to reduce Endeavor's
outstanding receivable balance from approximately $2.9 million, including
work-in-progress, to $950,000.

AESGEN, INC.

     Aesgen, Inc. ("Aesgen") was formally organized with an affiliate of the
Mayo Clinic and MOVA Pharmaceutical Corporation and funded in 1995 through the
issuance of approximately $11 million of nonconvertible, nonvoting, mandatorily
redeemable, preferred stock. The Company made a cash investment of $1.6 million
in such preferred stock, which is carried at cost, and is included in other
noncurrent assets on the balance sheet.

     In 1996, the Company sold to Aesgen marketing rights to a product under
development by the Company. Under the agreement, Aesgen paid a license fee and
will pay additional royalties upon marketing the product. AAI recognized net
sales of approximately $100,000, $200,000 and $1.9 million from Aesgen for the
years ended December 31, 1999, 1998 and 1997, respectively. AAI also had
accounts receivable of approximately $200,000 from Aesgen at December 31, 1999,
and work-in-progress of approximately $403,000 and $97,000 at December 31, 1999
and 1998 respectively. AAI has the right, under its development agreement with
Aesgen, to provide certain product development and support services to Aesgen
with respect to some generic drugs currently being developed by Aesgen, provided
that AAI's fees for such services are comparable to those of a competitor. In
addition, under such development agreement, the Company has agreed not to
develop, for its own account or any other person, a formulation of any of the
generic products currently under development for Aesgen and any additional drugs
that AAI agrees to develop in the future for Aesgen.

     Valuation allowances have been provided for certain assets resulting from
the Company's German acquisition in 1996 since realization of such assets cannot
be predicted with reasonable certainty at this time. As of December 31, 1999,
the Company had approximately $2.3 million of federal net operating loss
carryforwards, which begins to expire in 2012 and $10.0 million of state net
operating loss carryforwards with the following expirations: $600,000 in 2000,
$3.9 million in 2002, and $5.5 million in 2005.

8.  EMPLOYEE BENEFIT PLAN

     The Company provides retirement benefits for all domestic AAI employees
with one year of service through a defined contribution plan qualified under
section 401(k) of the Internal Revenue Code of 1986, as amended. Participants
may elect to contribute a portion of their annual compensation, subject to
limitations. The Company makes matching contributions in AAI stock equal to 50%
of a participant's contribution up to a certain amount. Additionally, the
Company makes profit-sharing contributions at the discretion of the Board of
Directors. The Company has expensed $607,000, $632,000 and $479,000 for the
years ended December 31, 1999, 1998 and 1997, respectively.

9.  COMMITMENTS AND CONTINGENCIES

     The Company leases land, buildings and equipment under renewable lease
agreements classified as operating leases. Rent expense under these agreements
for the years ended December 31, 1999, 1998 and 1997 was $3.2 million, $3.3
million, and $3.3 million, respectively. Future minimum rentals due under lease
agreements as of December 31, 1999 are $2.9 million -- 2000; $2.4
million -- 2001; $1.5 million -- 2002; $1.4 million -- 2003; $1.2
million -- 2004 and $5.2 million -- thereafter.

     The Company is party to lawsuits and administrative proceedings incidental
to the normal course of its business. In connection with the 1995 issuance of
the Series A Preferred, two of the Company's stockholders have agreed to
indemnify the Company for certain losses, if incurred. Management does not
believe that any liabilities related to such lawsuits or proceedings will have a
material adverse effect on the Company's financial condition, results of
operations or cash flows.

     On July 28, 1999, AAI filed a demand for arbitration against a former
client seeking approximately $700,000 for manufacturing services rendered. The
former client counterclaimed for $5 million alleging various misrepresentations
by the Company. On December 29, 1999, the former client filed suit in North
Carolina State Court contesting the arbitration and seeking several million
dollars in alleged damages. The Company counter sued the former client for
approximately $3.6 million, including interest, for various services rendered in
addition to the amounts owed for manufacturing services. The State Court ruled
in February that all claims under the manufacturing agreement are to be decided
under arbitration. A June 2000 date has been set for the arbitration. Discovery
has not yet commenced in the litigation. The Company and the former client are
attempting to negotiate a settlement in lieu of the arbitration and legal
proceedings, however, there can be no assurance that any settlement will occur.
The Company vigorously contests the misrepresentation claims and believes it is
entitled to the value of the services rendered. . The Company does not believe
that any future settlement will have a material adverse effect on the Company's
financial condition, results of operations or cash flows.

     The Company currently leases a facility adjacent to the Company's
laboratories from two banks. The facility was built in 1999 in Wilmington, North
Carolina. The Company's operating lease for this facility covers an initial
period of three years with two one-year renewal periods. At the end of the
initial term, the Company may elect to purchase the facility at fair market
value, extend the lease or the property may be sold.

10.  FINANCIAL INFORMATION BY BUSINESS SEGMENT AND GEOGRAPHIC AREA

     The Company operates in two business segments consisting of a
fee-for-service business and a product development business. The core services
provided on a fee-for-service basis to the worldwide pharmaceutical and
biotechnology industries worldwide include comprehensive formulation, testing
and manufacturing expertise, in addition to the ability to take investigational
products into and through human clinical trials. In the product development
segment, the Company internally develops drugs and technologies with the
objective of licensing marketing rights to third parties in exchange for license
fees and royalties. The Company does not independently commercialize products
developed internally or otherwise directly compete with its pharmaceutical
clients in the marketing or distribution of products. The majority of the
Company's non-U.S. operations are located in Germany.

                       APPLIED ANALYTICAL INDUSTRIES, INC.
                             1996 STOCK OPTION PLAN
                              AMENDED AND RESTATED


This 1996 Stock Option Plan has been amended and restated effective March 27,
2000 to (1) reflect changes effected due to the 1996 stock splits and subsequent
conversion of Class B Non-Voting Stock to Common Stock in 1996, and (2) amend
the 1996 Stock Option Plan Section 6 to provide employees thirty (30) days to
exercise options after termination of employment.

1.       PURPOSE

         The purpose of the Applied Analytical Industries, Inc. 1996 Stock
         Option Plan (the "Plan") is to promote the growth and profitability of
         Applied Analytical Industries, Inc. (the "Company") and its
         subsidiaries ("Subsidiaries") from time to time by increasing the
         personal participation of officers and key employees in the financial
         performance of the Company and by providing such officers and key
         employees with an equity opportunity in the Company. This purpose will
         be achieved through the grant of stock options ("Options") to purchase
         shares of Common Stock of the Company (the "Common Stock") subject to
         restrictions on transfer or such other restrictions as the
         administrators of the Plan may determine.

2.       ADMINISTRATION

         The Plan will be administered by the Company's Board of Directors (the
         "Board").

         The Board shall have complete authority to: (i) interpret all terms and
         provisions of the Plan consistent with law; (ii) select from the group
         of officers and key employees eligible to participate in the Plan the
         officers and key employees to whom Options shall be granted; (iii)
         within the limits established herein, determine the number of shares to

         authorizing such action to be taken, unless different provision is made
         by the By-Laws of the Company or by resolution of the Board.

3.       STOCK SUBJECT TO PLAN

         The stock to be offered under the Plan shall be authorized but unissued
         shares of Common Stock. An aggregate of 495,627 shares of Common Stock
         are reserved for issuance upon exercise of Options. Any or all of the
         Options granted under Section 4 hereof may, at the Board's discretion,
         be intended to qualify as incentive stock options (`Incentive Stock
         Options') under Section 422 of the Internal Revenue Code of 1986, as
         amended (the `Code'). The number of shares reserved under the Plan may
         be adjusted to reflect any change in the capitalization of the Company
         as contemplated by Section 9 hereof and occurring after the adoption of
         the Plan. The Board will maintain records showing the cumulative total
         of all shares subject to Options outstanding under the Plan.

4.       OPTION AWARDS

         (a) Eligibility and Factors Considered in Granting Options

         The grant of Options under this Section 4 shall be limited to those
         officers and key employees of the Company or any of its Subsidiaries
         who have the greatest contribution to the Company's long-term
         performance and are selected by the Board. In making any determination
         as to the officer(s) and key employees) to whom Options shall be
         granted under this Section 4 and as to the number of shares to be
         subject thereto, the Board shall take into account, in each case, the
         level and responsibility of the person's position, the level of the
         person's performance, the person's level of compensation, the assessed
         potential of the person and such additional factors as the Board shall
         deem relevant to the accomplishment of the purposes of the Plan.

         (b) Allotment of Shares

         The Board, in its sole discretion and subject to the provisions of the
         Plan, may grant to participants eligible under this Section 4, on or
         after the date hereof, Options. Options may be, at the discretion of
         the Board: (i) Options that are intended to qualify as Incentive Stock
         Options; or (ii) Options that are not intended to be Incentive Stock
         Options; or (iii) both of the foregoing, if granted separately, and not
         in tandem. Each Option granted under the Plan must be clearly
         identified as to its status as an Incentive Stock Option or not.

         Options granted under this Section 4 may be allotted to participants in
         such amounts, subject to the limitations specified in the Plan, as the
         Board, in its sole discretion, may from time to time determine,
         provided that no participant may be granted Options with respect to
         more than 253,000 shares of Common Stock.

         In the case of Options intended to be Incentive Stock Options, the
         aggregate fair market value (determined at the time of such Incentive
         Stock Options' respective grants) of the shares with respect to which
         Incentive Stock Options are exercisable for the first time by a
         participant hereunder during any calendar year (under all plans taken
         into account pursuant to Section 422(d) of the Code) shall not exceed
         $100,000. Options under this Section 4 not intended to qualify as
         Incentive Stock Options may be granted to any Plan participant without
         regard to the Section 422(d) limitations.


<PAGE>   3

         (c) Time of Granting Options

         The date of grant of an Option under this Section 4 shall be, for all
         purposes, the date on which the Board makes the determination of
         granting such Option (each such date, a "Grant Date"). Notice of the
         determination shall be given to each officer or key employee to whom an
         Option is so granted under this Section 4 within a reasonable time
         after the Grant Date.

         (d)      Exercise Price for Options

         The price per share at which each Option granted under this Section 4
         may be exercised shall be such price as shall be determined by the
         Board at the time of grant based on such criteria as may be adopted by
         the Board at the time of grant in good faith, taking into account, in
         each case, the market price of the common stock, the level and
         responsibility of the person's position, the level of the person's
         performance, the person's level of compensation, the assessed potential
         of the person, and such additional factors as the Board shall deem
         relevant to the accomplishment of the purposes of the Plan; provided,
         however, that in no event shall the exercise price per share of an
         Option be less than 100% of the fair market value of the Company's
         shares of common stock on the Grant Date for such Option unless such
         grant is approved by all directors and in no event shall be less than
         75% of the fair market value of the Company's shares of common stock on
         the Grant Date for such Option. In the case of an Option intended to
         qualify as an Incentive Stock Option, the price per share shall not be
         less than 100% (or 110% for owners of more than 10% of the total
         combined voting power of all classes of stock of the Company or any
         Subsidiary) of the fair market value of the Common Stock on the Grant
         Date for such Option.

         If the Company's shares of Common Stock are:

         (1)      actively traded on any national securities exchange or NASDAQ
                  system that reports their sales prices, fair market value
                  shall be the average of the high and low sales prices per
                  share on any Grant Date;

         (2)      otherwise traded over the counter, fair market value shall be
                  the average of the final bid and asked prices for the shares
                  of Common Stock as reported for any Grant Date; or

         (3)      not traded, the Board shall consider any factor or factors
                  that it believes affects fair market value, and shall
                  determine fair market value without regard to any restriction
                  other than a restriction that by its terms will never lapse.

         (e)      Term of Options

                  The term of each Option granted under this Section 4 shall be
                  established by the Board, but shall not exceed 10 years (or 5
                  years for owners of more than 10% of the total combined voting
                  power of all classes of stock of the Company or of a
                  Subsidiary) from the Grant Date for such Option.

         (f)      Cancellation and Replacement of Options

                  The Board may at any time or from time to time permit the
                  voluntary surrender by the holder of any outstanding Option
                  granted under this Section 4 where such surrender is



<PAGE>   4

                  conditioned upon the granting under this Section 4 to such
                  holder of new Option(s) for such number of shares as the Board
                  shall determine, or may require such a voluntary surrender as
                  a condition precedent to the grant under this Section 4 of new
                  Option(s) to such holder.

                  The Board shall determine the terms and conditions of any such
                  new Option(s), including their exercise price and the periods
                  during which they may be exercised, subject to and in
                  accordance with the provisions of the Plan, all or any of
                  which may differ from the terms and conditions of the
                  Option(s) surrendered. Any such new Option(s) shall be subject
                  to all the relevant provisions of the Plan.

                  The shares subject to any Option so surrendered or terminated
                  shall no longer be charged against the limitation or
                  limitations provided in Section 3 of the Plan and may
                  thereafter become the subject of new Option grants under the
                  Plan.

                  The granting of new Option(s) in connection with the surrender
                  of outstanding Option(s) under the Plan shall be considered
                  for the purposes of the Plan as the grant of new Option(s) and
                  not an alteration, amendment or modification of the Plan or of
                  the Option(s) being surrendered.

         (g)      Vesting

                  Except as otherwise determined by the Board or the Committee,
                  Options shall vest as follows:

                                                         Aggregate Percentage of
                                                          Shares under Options
                  Date                                     Vested on such Date
                  ----                                   -----------------------

                  Six months after Grant Date                      25%
                  Eighteen months after Grant Date                 50%
                  Thirty months after Grant Date                   75%
                  Forty-two months after Grant Date               100%

Notwithstanding the foregoing, any Option granted pursuant to this Plan shall be
deemed fully vested immediately prior to an Acquisition Transaction. For the
purposes of the Plan, an "Acquisition Transaction" shall mean and include the
following:

                           (i) The consummation of a tender offer or exchange
                           offer for the ownership of securities of the Company
                           representing 51 % or more of the combined voting
                           powers of the Company's then outstanding voting
                           securities;


                           (ii) The adoption by the Company's stockholders of a
                           plan of merger or consolidation providing for the
                           merger or consolidation of the Company with another
                           corporation (other than an affiliate of the Company
                           within the meaning of the Securities Exchange Act of
                           1934, as amended) and as a result of such merger or
                           consolidation less than 75% of the outstanding voting
                           securities of the surviving or resulting corporation
                           would then be owned in the aggregate by the former
                           stockholders of the Company; or



<PAGE>   5

                           (iii) The transfer by the Company of substantially
                           all of its assets to another corporation or entity
                           which is not a wholly owned subsidiary of the
                           Company.

5.       NON-TRANSFERABILITY

         An Option granted to a participant under the Plan shall not be
         transferable by him or her except: (i) by will; (ii) by the laws of
         descent and distribution; or (iii) pursuant to a qualified domestic
         relations order as defined by the Code or in Title I of the Employee
         Retirement Income Security Act, or the rules thereunder. In the case of
         an Option intended to be an Incentive Stock Option, such Option shall
         not be transferable by a participant other than by will or the laws of
         descent and distribution and during the optionee's lifetime shall be
         exercisable only by him or her.

6.       EXERCISABILITY OF OPTIONS

         Subject to the provisions of the Plan, Options granted under Section 4
         hereof shall be exercisable at such time or times after the Grant Date
         to the extent such Options are vested.

         Any Option shall terminate in full (whether or not previously
         exercisable) prior to the expiration of its term on the date thirty
         (30)days after the date the optionee ceases to be an employee of the
         Company or any Subsidiary of the Company, unless (i) the optionee shall
         (a) die while an employee of the Company or such Subsidiary, in which
         case the participant's legatee(s) under his or her last will or the
         participant's personal representative or representatives may exercise
         all or part of the previously unexercised portion of such Option at any
         time within one year, but not beyond the expiration of its term, after
         the participant's death to the extent the optionee could have exercised
         the Option immediately prior to his or her death, (b) become
         permanently or totally disabled within the meaning of section 22(e)(3)
         of the Code (or any successor provision) while an employee of the
         Company or such Subsidiary, in which case the participant or his or her
         personal representative may exercise the previously unexercised portion
         of such Option at any time within one year, but not beyond the
         expiration of its term, after termination of his or her employment or
         directorship to the extent the optionee could have exercised the Option
         immediately prior to such termination, or (c) resign or retire after
         age 62 with the consent of the Company, in which case the participant
         may exercise the previously unexercised portion of such Option at any
         time within six months, but not beyond the expiration of its term,
         after the participant's resignation or retirement to the extent the
         optionee could have exercised the Option immediately prior to such
         resignation or retirement, or (ii) the Board shall determine otherwise.

         In no event may an Option be exercised after the expiration of its
         fixed term.

7.       METHOD OF EXERCISE

         Each Option granted under the Plan shall be deemed exercised when the
         holder (a) shall indicate the decision to do so in writing delivered to
         the Company, (b) shall at the same time tender to the Company payment
         in full of the exercise price for the shares for which the Option is
         exercised, which payment may be made in cash, and (e) shall comply with
         such other reasonable requirements as the Board may establish; provided
         that in order to enable an optionee (including but not limited to
         officers) to exercise options granted under the Plan, the



<PAGE>   6

         Board may determine, in the exercise of its discretion, to (i) cause
         the Company to lend money or other property to such optionee upon such
         terms and conditions and in such amounts as the Board may determine,
         (ii) grant such optionee permission to pay the exercise price in
         installments, or to accept such optionee's note as whole or partial
         payment, (iii) permit such optionee to repay loans made by the Company
         to such optionee for the exercise of options with issued and
         outstanding shares of common stock, (iv) grant such optionee permission
         to pay the exercise price by delivering for cancellation Options having
         an aggregate value (calculated by subtracting the exercise price per
         share from the fair market value of a share of Common Stock) equal to
         the total amount of the exercise price, or (v) provide such financial
         assistance to such optionee as the Board determines to be desirable.
         The exercise of any option granted under the Plan may be made subject
         to the condition that, if at any time the Board shall determine, in its
         discretion, that the satisfaction of withholding tax or other
         withholding liabilities under any state or federal law is necessary or
         desirable as a condition of, or in connection with, such exercise or
         the delivery or purchase of shares pursuant thereto, then in such
         event, the exercise of the option shall not be effective unless such
         withholding tax or other withholding liabilities shall have been
         satisfied in a manner acceptable to the Company, which may include the
         withholding by the Company of shares of Common Stock to be issued upon
         exercise of an Option having a fair market value equal to the required
         withholding amount. With respect to the foregoing sentences, the value
         of the shares of Common Stock shall be the fair market value determined
         in accordance with Section 4(d) of the Plan as of the day of such
         payment or withholding.

         No person, estate or other entity shall have any of the rights of a
         shareholder with reference to shares subject to an Option until a
         certificate for the shares has been delivered.

         An Option granted under the Plan may be exercised for any lesser number
         of shares than the full amount for which it could be exercised. Such a
         partial exercise of an Option shall not affect the right to exercise
         the Option from time to time in accordance with the Plan for the
         remaining shares subject to the Option.

8.       TERMINATION OF OPTIONS

         An Option granted under the Plan shall be considered terminated in
         whole or in part, to the extent that, in accordance with the provisions
         of the Plan and such Option, it can no longer be exercised for any
         shares originally subject to the Option.


9.       ADJUSTMENTS UPON CHANGES IN CAPITALIZATION

         In the event of any change in the outstanding Common Stock of the
         Company by reason of a stock dividend, stock split, stock
         consolidation, recapitalization, reorganization, merger, split up or
         the like, the shares available for purposes of the Plan or under option
         in outstanding option agreements pursuant to the Plan (and the option
         price under such agreements) shall be appropriately adjusted so as to
         preserve, but not increase, the benefits of the Plan to the Company and
         the benefits to the holders of such Options; Provided, however, that
         for any Incentive Stock Options, in the case of a corporate merger,
         consolidation, acquisition of property or stock, separation,
         reorganization or liquidation, the excess of the aggregate fair market
         value of the shares subject to any Options immediately after such event
         over the aggregate option price of such shares is not more than the
         excess of the aggregate fair market



<PAGE>   7

         value of all shares subject to such Options immediately before such
         event over the aggregate option price of such shares.

         Adjustments under this Section shall be made by the Board, whose
         determination as to what adjustments shall be made and the extent
         thereof, shall be final, binding and conclusive.

10.      COMPLIANCE WITH SECURITIES LAWS AND OTHER REQUIREMENTS

         No certificate(s)for shares shall be executed and delivered upon
         exercise of an Option until the Company shall have taken such action,
         if any, as is then required to comply with the provisions of the
         Securities Act of 1933, as amended, the North Carolina Uniform
         Securities Act, as amended, any other applicable state securities
         law(s) and the requirements of any exchange on which the Common Stock
         may, at the time, be listed.

         In the case of the exercise of an Option by a person or estate
         acquiring the right to exercise the Option by bequest or inheritance,
         the Board may require reasonable evidence as to the ownership of the
         Option and may require such consents and releases of taxing authorities
         as it may deem advisable.

11.      NO RIGHT TO EMPLOYMENT

         Neither the adoption of the Plan nor its operation, nor any document
         describing or referring to the Plan, or any part thereof, shall confer
         upon any employee participant under the Plan any right to continue in
         the employ of the Company, or shall in any way affect the right and
         power of the Company to terminate the employment or position with the
         Company of any participant under the Plan at any time with or without
         assigning a reason therefor, to the same extent as the Company might
         have done if the Plan had not been adopted.

12.      EFFECTIVE DATE OF THE PLAN

         The Plan was adopted by the Board on November 16, 1995, and shall be
         effective until November 16, 2005, after which time no Option shall be
         granted, but such termination shall not affect any Option previously
         granted under the Plan.


13.      STOCK CERTIFICATE LEGEND.

         Each stock certificate issued for options intended to be Incentive
         Stock Options shall bear the following legend:

         THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ACQUIRED PURSUANT TO A
         STOCK OPTION PLAN AND WERE INTENDED TO BE A QUALIFIED OPTION AS SET

                  Stock to be issued upon exercise of an Option having a fair
                  market value equal to the required withholding amount.

                                      LOANS

         2.01     REVOLVING LOANS.

         Subject to the terms and conditions and relying upon the
representations and warranties herein set forth, the Bank agrees to make
Revolving Loans to the U.S. Borrower, at any time and from time to time until
the Maturity Date, in an aggregate principal amount at any time outstanding not
to exceed the lesser of (i) TWENTY-FIVE MILLION DOLLARS ($25,000,000) (the
"Revolving Loan Committed Amount") and (ii) the Borrowing Base, for purposes of
financing the U.S. Borrower's working capital needs. The U.S. Borrower may
borrow, repay and reborrow hereunder on or after the date hereof and prior to
the Maturity Date, subject to the terms, provisions and limitations set forth
herein. The outstanding principal balance of the Revolving Loans, together with
all accrued but unpaid interest, fees and other charges, shall be due and
payable in full on the Maturity Date.

         2.02     REVOLVING NOTE.

         The Revolving Loans made by the Bank shall be evidenced by the
Revolving Note duly executed by the U.S. Borrower, dated the Closing Date, in
substantially the form of Exhibit 2.02 attached hereto, payable to the order of
the Bank in a principal amount equal to the Revolving Loan Committed Amount.

         2.03     INTEREST ON REVOLVING LOANS.

         Subject to section 3.01 hereof, the outstanding principal balance of
the Revolving Loans shall bear interest at a rate equal to the Adjusted LIBOR

         2.05     DEUTSCHE MARK LOAN.

                  (a) Subject to the terms and conditions hereof, the Bank
         agrees to make on or before March 31, 2000 a term loan to the German
         Borrower in Deutsche Marks in an aggregate principle amount equal to DM
         12,000,000 (the "Deutsche Mark Loan"). Amounts repaid on the Deutsche
         Mark Loan may not be reborrowed. The outstanding principal balance of
         the Deutsche Mark Loan, together with all accrued but unpaid interest,
         fees and other charges, shall be due and payable in full on the
         Maturity Date. The proceeds of the Deutsche Mark Loan will be used by
         the German Borrower to repay in full loans made to the German Borrower
         by its German banks, which loans have been supported by standby letters
         of credit issued by the Bank.

                  (b) The Deutsche Mark Loan shall be made, shall be repaid and
         shall bear interest in accordance with the terms of a Promissory Note
         dated the Closing Date and executed by the German Borrower in favor of
         the Bank in substantially the form of Exhibit 2.05 (the "Deutsche Mark
         Note"), the terms of which are incorporated herein by reference.

                  (c) (i) If, as a result of the implementation of the European
                  economic and monetary union ("EMU"), (i) any currency
                  available for borrowing under this Credit Agreement (a
                  "national currency") ceases to be lawful currency of the state
                  issuing the same and is replaced by a European single or
                  common currency (the "Euro") or (ii) any national currency and
                  the Euro are at the same time both recognized by the central
                  bank or comparable governmental authority of the state issuing
                  such currency as lawful currency of such state, then any
                  amount payable hereunder by any party hereto in such national
                  currency shall instead be payable in the Euro and the amount
                  so payable shall be determined by redenominating or converting
                  such amount into the Euro at the exchange rate officially
                  fixed by the European Central Bank for the purpose of
                  implementing the EMU, provided, that to the extent any EMU
                  legislation provides that an amount denominated either in the
                  Euro or in the applicable national currency can be paid either
                  in Euros or in the applicable national currency, each party to
                  this Loan Agreement shall be entitled to pay or repay such
                  amount in Euros or in the applicable national currency. Prior
                  to the occurrence of the event or events described in clause
                  (i) or (ii) of the preceding sentence, each amount payable
                  hereunder in any such national currency will, except as
                  otherwise provided herein, continue to be payable only in that
                  national currency.

                           (ii) The Borrowers shall from time to time, at the
                  request of the Bank, pay to the Bank for the account of the
                  Bank the amount of any cost or increased cost incurred by, or
                  of any reduction in any amount payable to or in the effective
                  return on its capital to, or of interest or other return
                  foregone by, the Bank or any holding company of the Bank as a
                  result of the introduction of, changeover to or operation of
                  the Euro in any applicable state.

                           (iii) In addition, this Loan Agreement and the
                  Deutsche Mark Note (including, without limitation, the
                  definition of Adjusted LIBOR Rate) will be amended to the
                  extent determined by the Bank (acting reasonably and in
                  consultation with the Borrowers) to be necessary to reflect
                  such implementation of the EMU and change in currency and to
                  put the Bank and the Borrowers in the same position, so far as
                  possible, that they would have been in if such implementation
                  and change in currency had not occurred. Except as provided in
                  the foregoing provisions of this Section, no such
                  implementation or change in currency nor any economic
                  consequences resulting therefrom shall (i) give rise to any
                  right to terminate prematurely, contest, cancel, rescind,
                  alter, modify or renegotiate the provisions of this Loan
                  Agreement or (ii) discharge, excuse or otherwise affect the
                  performance of any obligations of the German Borrower under
                  this Loan Agreement, the Deutsche Mark Note or other Loan
                  Documents.


                                   ARTICLE III

                 ADDITIONAL PROVISIONS REGARDING REVOLVING LOANS

         3.01     DEFAULT RATE.

         If a Borrower shall default in the payment when due (subject to
applicable grace periods, if any) of the principal of or interest on any Loan or
any other amount becoming due hereunder, such Borrower shall on demand from time
to time pay interest on any overdue payment of principal and, to the extent
permitted by law, on overdue payments of interest up to the date of actual
payment (after as well as before judgment):

                           (i) in the case of principal of or interest on a Loan
         at a rate equal to 2% per annum above the rate which would otherwise be
         payable hereunder; and

                           (ii) in the case of any other amount payable
         hereunder or under any of the other Loan Documents (other than
         principal of or interest on any Loan referred to in clause (i) above),
         at a rate 2% per annum above the Prime Rate.

         3.02     PREPAYMENTS.

                  (a) Voluntary Prepayments. The Borrowers shall have the right
         at any time and from time to time to prepay any Loan in whole or in
         part, without premium or penalty; provided, however, partial
         prepayments of any Loan shall be applied to principal installments
         thereunder in the inverse order of maturities.

                  (b) Mandatory Prepayments. If at any time the aggregate
         outstanding principal amount of Revolving Loans shall exceed the lesser
         of (i) the Revolving Loan Committed Amount and (ii) the Borrowing Base,
         the U.S. Borrower immediately shall prepay the Revolving Loans in an
         amount sufficient to eliminate such excess.

<PAGE>   14

         3.03     CAPITAL ADEQUACY.

                  (a) In the event that the Bank shall have determined that the
         adoption or implementation on or after the Closing Date under the
         Existing Loan Agreement of any applicable law, rule, regulation or
         guideline regarding capital adequacy, or any change therein, or any
         change in the interpretation or administration thereof by any
         governmental authority, central bank or comparable agency charged with
         the interpretation or administration thereof or by any court, or
         compliance by the Bank (or any lending office of the Bank) with any
         request or directive made or issued after the Closing Date regarding
         capital adequacy (whether or not having the force of law) of any such
         authority, central bank or comparable agency, has or would have the
         effect of reducing the rate of return on the Bank's capital as a
         consequence of its obligations hereunder to a level below that which
         the Bank could have achieved but for such adoption, change or
         compliance (taking into consideration the Bank's policies as the case
         may be, with respect to capital adequacy) by an amount deemed by the
         Bank to be material, then from time to time the Borrowers shall pay to
         the Bank such additional amount or amounts as will compensate the Bank
         for any such reduction suffered; provided, however, that no such
         amounts shall be payable with respect to a reduction in rate of return
         incurred more than 90 days before the Bank demands compensation under
         this Section.

                  (b) Failure on the part of the Bank to demand compensation for
         any reduction in return on capital with respect to any period shall not
         constitute a waiver of the Bank's rights to demand compensation for any
         reduction in return on capital in such period or in any other period.
         The protection of this Section shall be available to the Bank
         regardless of any possible contention of invalidity or inapplicability
         of the law, regulation or condition which shall have been imposed.

         3.04     INCREASED COSTS.

         At any time that the Bank shall incur increased costs or reductions in
the amounts received or receivable hereunder with respect to any Loan because of
any change since the Closing Date under the Existing Loan Agreement in any
applicable law, governmental rule, regulation, guideline or order (or in the
interpretation or administration thereof and including the introduction of any
new law or governmental rule, regulation, guideline or order) including without
limitation the imposition, modification or deemed applicability of any reserves,
deposits or similar requirements as related to such Deutsche Mark Loan (such as,
for example, but not limited to, a change in official reserve requirements, but,
in all events, excluding reserves to the extent included in the computation of
the Adjusted LIBOR Rate), then the Borrower shall pay to the Bank within 15 days
after written demand therefor (which demand shall state the basis therefor),
such additional amounts (in the form of an increased rate of, or a different
method of calculating, interest or otherwise as the Bank may determine in its
reasonable discretion) as may be required to compensate the Bank for such
increased costs or reductions in amounts receivable hereunder. Upon determining
in good faith that any additional amounts will be payable pursuant to this
subsection, the Bank will give prompt written notice thereof to the Borrower,
which notice shall set forth in reasonable detail the basis of the calculation
of such additional amounts.

         3.05     TAXES, ETC.

                  (a) All payments made by a Borrower hereunder, under a Note or
         under any Loan Document will be made without set-off, counterclaim,
         deduction or other defense. All such payments shall be made free and
         clear of and without deduction for any present or future income,
         franchise, sales, use, excise, stamp or other taxes, levies, imposts,
         deductions, charges, fees, withholdings, restrictions or conditions of
         any nature now or hereafter imposed, levied, collected, withheld or
         assessed by any jurisdiction (whether pursuant to United States
         Federal, state, local or foreign law) or by any political subdivision
         or taxing authority thereof or therein, and all interest, penalties or
         similar liabilities, excluding taxes on the overall net income of the
         Bank (such nonexcluded taxes are hereinafter collectively referred to
         as the "Taxes"). If a Borrower shall be required by law to deduct or to
         withhold any Taxes from or in respect of any amount payable hereunder,
         (i) the amount so payable shall be increased to the extent necessary so
         that after making all required deductions and withholdings (including
         Taxes on amounts payable to the Bank pursuant to this sentence) the
         Bank receives an amount equal to the sum it would have received had no
         such deductions or withholdings been made, (ii) such Borrower shall
         make such deductions or withholdings, and (iii) such Borrower shall pay
         the full amount deducted or withheld to the relevant taxation authority
         in accordance with applicable law. Whenever any Taxes are payable by a
         Borrower, as promptly as possible thereafter, such Borrower shall send
         the Bank an official receipt showing payment. In addition, each
         Borrower agrees to pay any present or future taxes, charges or similar
         levies which arise from any payment made hereunder or from the
         execution, delivery, performance, recordation or filing of, or
         otherwise with respect to, this Loan Agreement, the Notes or any other
         Loan Document (hereinafter referred to as "Other Taxes").

                  (b) The U.S. Borrower will indemnify the Bank for the amount
         of Taxes or Other Taxes (including, without limitation, any Taxes or
         Other Taxes imposed by any jurisdiction on amounts payable under this
         Section 3.05) paid by the Bank (including penalties, interest and
         expenses for nonpayment, late payment or otherwise) arising therefrom
         or with respect thereto, whether or not such Taxes or Other Taxes were
         correctly or legally asserted. This indemnification shall be paid
         within 30 days from the date on which the Bank makes written demand.

                  (c) If the U.S. Borrower fails to perform its obligations
         under this Section 3.05, the U.S. Borrower shall indemnify the Bank for
         any incremental taxes, interest or penalties that may become payable as
         a result of any such failure.

         3.06     PAYMENTS AND COMPUTATIONS.

         5.09     ERISA.

         No Credit Party has incurred any accumulated unfunded deficiency within
the meaning of the Employee Retirement Income Security Act of 1974 ("ERISA") or
incurred any material liability to the Pension Benefit Guaranty Corporation
("PBGC") established under such Act (or any successor thereto under such Act) in
connection with the employee benefit plans established or maintained by the
Credit Parties. Each Credit Party is in compliance in all material respects with
those provisions of ERISA and the regulations and public interpretations
thereunder which are applicable to the U.S. Borrower and its Subsidiaries. No
Reportable Event (as defined in ERISA) has occurred with respect to any Plan.

         5.10     SUBSIDIARIES.

         The U.S. Borrower has no Subsidiaries as of the date hereof except as
set forth on Exhibit 5.10 attached hereto.

         5.11     REGULATION U.

         No Borrower is engaged principally, or as one of its important
activities, in the business of extending credit for the purpose of purchasing or
carrying margin stock (within the meaning of Regulation U of the Board of
Governors of the Federal Reserve System). The proceeds of the Loans will be used
for the purposes described in Article II and not for the purpose of purchasing
or carrying margin stock.

         5.12     PATENTS AND TRADEMARKS.

         Each Credit Party possesses all of the necessary patents, licenses,

material to conduct its business as now conducted, without known conflict with
any patent, license, trademark, tradename or copyright of any other Person.

         5.13     FINANCIAL INFORMATION PROVIDED.

         The U.S. Borrower represents that the financial information it has
heretofore furnished to the Bank dated September 30, 1999 with regard to its
operations is true and correct, and presents fairly the financial position of
the U.S. Borrower, and there have been no material adverse changes since that
date.

         5.14     ENVIRONMENTAL COMPLIANCE.

         Each Credit Party has fully complied with all laws, ordinances,
regulations and orders, including without limitation all zoning, safety and
environmental laws, ordinances, regulations and orders, applicable to its
business or properties and the present uses by such Credit Party of its
properties do not violate any such laws, ordinances, regulations or orders.
There is not currently and in the past there has not been (i) any use,
treatment, storage or disposal of any hazardous



                                       16
<PAGE>   21

substance or material or pollutant on any of the such Credit Party's properties,
except as of the date hereof as disclosed on Exhibit 5.14 attached hereto, (ii)
any spill, leakage, discharge or release of any hazardous substance or material
or pollutant thereon or therefrom, or (iii) any off-site disposal by the such
Credit Party of any hazardous substance or material or pollutant in any
location, except as disclosed on Exhibit 5.14 attached hereto.

         5.15     YEAR 2000 COMPLIANCE.

         The U.S. Borrower has (i) initiated a review and assessment of all
areas within its and each of its Subsidiaries' businesses and operations
(included those affected by suppliers, vendors and customers) that could be
adversely affected by the "Year 2000 Problem" (that is, the risk that computer
applications may not be able to recognize and properly perform date-sensitive
functions after December 31, 1999), (ii) developed a plan and timeline for
addressing the Year 2000 Problem on a timely basis, and (iii) to date,
implemented that plan in accordance with that timetable. Based on the foregoing,
each Credit Party believes that all computer applications (including those of
its suppliers, vendors and customers) that are material to its or any of its
Subsidiaries' business and operations are reasonably expected on a timely basis
to be able to perform properly date-sensitive functions for all dates before and
after January 1, 2000 (that is, be "Year 2000 Compliant"), except to the extent
that a failure to do so could not reasonably be expected to have a material
adverse effect on such Credit Party.

         existence as of the date hereof or which is entered into subsequent to
         the date hereof;

                  (f) if a Credit Party in the performance of any other

         of Default described in Section 8.01(d) in which case such indebtedness
         shall become due and payable immediately without necessity of written
         demand) without the necessity of any other demand, presentment, protest
         or notice upon a Credit Party, all of which are hereby expressly waived
         by the Credit Parties.

                  (c) Acceleration of Obligations. All of the obligations of the
         Credit Parties under the Loan Documents shall thereupon be immediately
         due and payable without the necessity of any other demand, presentment,
         protest or notice upon a Credit Party, all of which are hereby
         expressly waived by the Credit Parties.

                  (d) Right of Set-Off. Regardless of the adequacy of the
         collateral, the Bank shall have the right, immediately and without
         further action by it, to set-off against a Note, all money owed by the
         Bank in any capacity to a Credit Party, whether or not due, and the
         Bank shall be deemed to have exercised such right of set-off and to
         have made a charge against any such money immediately upon the
         occurrence of such event of default even though such charge is made or
         entered on the books of the Bank subsequent thereto.

         If the Bank exercises its right of set-off described in this paragraph,
         it will provide the U.S. Borrower, in adequate detail, a description of
         all amounts set-off against a Note.

         Credit Parties and the Bank, and thereafter this Loan Agreement shall

                                    ARTICLE X

                                    GUARANTY

         10.01    GUARANTY.

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



                                       30
<PAGE>   35

grace periods) in accordance with the terms of such extension or renewal. This
is a guaranty of payment and not of collection.

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

         10.02    OBLIGATIONS UNCONDITIONAL.

         The obligations of the Guarantors under Section 10.01 hereof are
absolute and unconditional, irrespective of the value, genuineness, validity,
regularity or enforceability of this Agreement or any of the other Loan
Documents, or any other agreement or instrument referred to herein or therein or
relating hereto or thereto, or any substitution, release or exchange of any
other guarantee of or security for any of the Guaranteed Obligations, and, to
the fullest extent permitted by applicable law, irrespective of any other
circumstance whatsoever which might otherwise constitute a legal or equitable
discharge or defense of a surety or guarantor, it being the intent of this
Section 10.02 that the obligations of the Guarantors hereunder shall be absolute
and unconditional under any and all circumstances. Each of the Guarantors agrees
that it shall have no right of subrogation, indemnity, reimbursement or
contribution against a Borrower or any other guarantor for amounts paid under
this Guaranty until such time as the Bank has been paid in full, the Commitment,
if any, has been terminated and no Person or governmental authority shall have
any right to request any return or reimbursement of funds from the Bank in
connection with monies received under the Loan Documents. Without limiting the
generality of the foregoing, it is agreed that, to the fullest extent permitted
by law, the occurrence of any one or more of the following shall not alter or
impair the liability of the Guarantors hereunder which shall remain absolute and
unconditional as described above:

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

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

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



                                       31
<PAGE>   36

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

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

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

         10.03    REINSTATEMENT.

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

         10.04    CERTAIN ADDITIONAL WAIVERS.

         Without limiting the generality of the provisions of this Article X,
each Guarantor hereby specifically waives the benefits of N.C. Gen. Stat. ss.ss.
26-7 through 26-9 inclusive. Each of the Guarantors agrees that it shall have no
right of recourse to security for the Guaranteed Obligations, except through the
exercise of the rights of subrogation pursuant to Section 10.02.

         10.05    REMEDIES.

         Each of the Guarantors agrees that, to the fullest extent permitted by
law, as between the Guarantors, on the one hand, and the Bank, on the other
hand, the Guaranteed Obligations may be declared to be forthwith due and payable
as provided in Article VIII hereof (and shall be deemed to have become
automatically due and payable in the circumstances provided in said Article
VIII) for purposes of Section 10.01 hereof notwithstanding any stay, injunction
or other prohibition preventing such declaration (or preventing the Guaranteed
Obligations from becoming automatically due and payable) as against any other
Person and that, in the event of such declaration (or the Guaranteed Obligations
being deemed to have become automatically due and payable), the Guaranteed
Obligations (whether or not due and payable by any other Person) shall forthwith



                                       32
<PAGE>   37

become due and payable by the Guarantors for purposes of said Section 10.01. The
Guarantors acknowledge and agree that their obligations hereunder are secured in
accordance with the terms of the Security Documents and that the Bank may
exercise remedies thereunder in accordance with the terms thereof.

         10.06    CONTINUING GUARANTEE.

         The guarantee in this Article X is a continuing guarantee, and shall
apply to all Guaranteed Obligations whenever arising.

         10.07    RIGHTS OF CONTRIBUTION.

                  (a) With respect to the Domestic Subsidiaries in their
         capacities as Guarantors, such Guarantors agree among themselves that,
         in connection with payments made hereunder, each such Guarantor shall
         have contribution rights against the other such Guarantors as permitted
         under applicable law. Such contribution rights shall be subordinate and
         subject in right of payment to the obligations of such Guarantors under
         the Loan Documents and no such Guarantor shall exercise such rights of
         contribution until all Guaranteed Obligations have been paid in full
         and the Commitment terminated.

                  (b) With respect to the U.S. Borrower and the Foreign
         Subsidiaries in their capacities as Guarantors, such Guarantors agree
         among themselves that, in connection with payments made hereunder, each
         such Guarantor shall have contribution rights against the other such
         Guarantors as permitted under applicable law. Such contribution rights
         shall be subordinate and subject in right of payment to the obligations
         of such Guarantors under the Loan Documents and no such Guarantor shall
         exercise such rights of contribution until all Guaranteed Obligations
         have been paid in full and the Commitment terminated.

                          INDEPENDENT AUDITORS' REPORT


To the Board of Directors
Medical & Technical Research Associates, Inc.


We have audited the accompanying balance sheet of Medical & Technical Research
Associates, Inc. as of December 31, 1997, and the related statements of
operations, stockholders' equity, and cash flows for the year then ended. 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 audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Medical & Technical Research
Associates, Inc. as of December 31, 1997, and the results of its operations and
its cash flows for the year then ended, in conformity with generally accepted
accounting principles.
