Item 1. Business

General

The Company is a contract research organization (CRO) providing research
and development resources to many of the leading pharmaceutical, medical device
and biotechnology companies in the world. The Company prides itself on its
contributions to basic understanding of the underlying causes of central nervous
system disorders, diabetes, osteoporosis and other diseases since 1974. The
Company has played a significant role in the development of technologies and
drugs with current revenues in excess of $15 billion for its clients.

The Company offers an efficient, variable-cost alternative to its clients'
internal product development, compliance and quality control programs. The
Company first focused on providing new products and procedures that facilitated
research at client sites. Increasing pressures to bring products to market
faster and more cost effectively prompted many clients to ask the Company to
carry out proprietary projects in the Company's research facilities. Many of
these clients had a prior relationship with the Company. To reduce overhead and
speed drug approvals through the Food and Drug Administration (FDA),
pharmaceutical companies are contracting increasing amounts of their development
work to outside firms such as the Company. As a result, the Company now derives
its revenues from both the sale of its research services and drug development
tools. The Company provides a range of value-added services and products focused
on chemical analysis and preclinical metabolism, allowing its clients to perform
their research and development either in house or at the Company.

The Company's services and products combine basic research with diagnostic
and therapeutic experience. One consequence of the restructuring of the
healthcare industry is the greater reliance on outsourced research services. The
Company is capable of supporting the clinical development (formulations and
clinical trials) and preclinical needs of researchers and clinicians, for small
molecule drugs and hormones through large biomolecules such as proteins. The
Company believes their scientists have the skills necessary in instrumentation,
chemical reagents, computer software, physiology, and pathology, as well as the
global presence to make the services and products it provides increasingly
valuable to the worldwide pharmaceutical, medical device and biotechnological
industries.

Over the past five years, the Company has regularly provided its services
and/or products to the top 25 pharmaceutical companies in the world, as ranked
by 1999 research and development spending. In fiscal 2000, the Company estimates
that more than one-half of its total revenue was derived from these companies.
As a result of its (i) client focus, (ii) reputation for high-quality services
and products, (iii) capital investment in cutting-edge instrumentation,
facilities and new service offerings, (iv) skilled and experienced professional
staff and (v) expertise in performing critical development and support services,
the Company believes that it is a value-added partner in solving its clients'
complex product development problems.

The Company's development and preclinical services support screening and
pharmacological testing, preclinical/safety testing, formulation development,
regulatory and compliance consulting and quality control testing. The
Pharmaceutical Research and Manufacturing Association (PhRMA) estimates that in
1999, pharmaceutical and biotechnology companies spent approximately $26 billion
worldwide on research and development, of which approximately 25%, or $6.6



- 3 -


billion, was outsourced to independent contract service providers. The Company
believes that this outsourcing trend will continue as a result of pressure
toward accelerated drug development, managed care cost containment, better
disease management, shorter product exclusivity, generic competition, strategic
alliances, mergers and acquisitions, virtual drug company and biotechnology
industry growth, the need for technical and data management expertise and the
globalization of pharmaceutical development.

The Company designs, manufactures and markets a broad range of products and
related scientific methods that detect and quantify chemicals and monitor their
effect on biological systems. The Company also competes in subsets of the $17
billion per year analytical instrument industry. The Company's focus, however,
is not on marketing hardware and software. Rather, it develops solutions to
challenging problems, which permit the Company to use its talented personnel in
providing a total solution not generally offered by hardware-focused
competitors. The Company develops and manufactures state-of-the-art liquid
chromatography, electrochemistry, physiology and in vivo sampling systems. These
instruments are sold primarily to pharmaceutical research organizations.
Principal clients of the Company include scientists engaged in drug metabolism
studies, pharmacokinetics and basic neuroscience research.

Changing Nature of the Pharmaceutical Industry

The Company provides services and products globally to pharmaceutical,
medical device and biotechnology companies, academic institutions and
governments to facilitate research and development. The Company's services are
generally marketed to pharmaceutical and other biotech companies engaged in
later stages of developmental pharmaceutical testing, while the Company's
products are generally marketed to both public and private research
organizations engaged in the early stages of drug development. The research
services industry is highly fragmented, consisting of several hundred vendors
operating in niches and a small number of larger companies focused on an ever-
growing portfolio of cradle-to-grave pharmaceutical development services.

The Company's products business competes against several large equipment
manufacturers. While the markets for the Company's services and products have
distinct customers (often separate divisions in a single large pharmaceutical
company) and requirements, the Company believes that both markets are facing
increased pressure to outsource certain facets of their research and development
activities. The Company believes that the factors identified below will
contribute to a continuing increase in outsourcing activities by its customers.

Accelerated Drug Development

Consumers, physicians, health care providers and pharmaceutical company
shareholders continue to demand faster, more efficient drug development.
Pharmaceutical companies are accelerating the drug development process. New
combinatorial synthetic techniques, high throughput screening, novel genomic
targeting and other technologies are generating an unprecedented number of new
drug candidates. Pharmaceutical developers are relying on external service
providers for testing and analysis in all phases of development. Clients demand
fast, quality service and immediate informed decisions to quickly exclude poor
candidates and speed development of successful ones.

Cost Containment

Pharmaceutical companies are facing increasing pressure to develop more
efficient operating strategies due to factors listed here, plus increased
purchasing power of large buyer groups and governmental initiatives designed to
reduce drug prices. The Company believes that the pharmaceutical and medical
device industries are limiting the growth of internal research programs and
favoring outsourcing. The need for additional development capacity to speed new
product development, maximize market exclusivity and increase profitability
drives the need for outsourced services.

Patent Expiration

Patents on all pharmaceuticals age and expire. Since 1984, prescriptions
for generic drugs have risen from 18.6% to 47% of all prescriptions written.
Generic market penetration can cut an estimated 2 to 5 years from effective
patent protection for brand name drugs. Drug companies are developing new
products or modifying existing products to maintain market share against generic
product competition. The Company believes that the pressure to develop new
products and to modify or reformulate existing products, combined with internal
capacity constraints, will lead clients to outsource development.



- 4 -


Shorter Exclusivity

The Competition and Patent Term Restoration Act of 1984 shortened the
approval time of generic copies of approved drugs. PhRMA notes that newer drugs
experience generic competition much sooner after patent expiration than older
drugs. In 1992, 72% of drugs coming off patent saw generic competition in 18
months.

New breakthrough drugs, those first in their therapeutic class, are
experiencing abbreviated exclusivity as new chemical entities penetrate this
new, proven, profitable end use. Where Tagamet(R) saw no competitive pressure
for ten years, Celebrex(R) began to lose share to Vioxx(R) in three months.

Strategic Alliances

Strategic alliances allow pharmaceutical companies to share research
know-how and to develop and market new drugs faster in more diverse, global
markets. There were 121 reported alliances in 1986, which increased to 712 in
1998. The Company believes that alliances will lead to a greater number of
potential drugs in testing, many under study by new companies lacking broad
technical resources.

Mergers and Acquisitions

Consolidation in the pharmaceutical industry is becoming commonplace. As
firms blend personnel, resources and business activities, the Company believes
they will continue to streamline operations, optimizing staffing and leading to
more outsourcing. This may result in short-term disruption in placement of, or
progress on, drug development programs as merging companies rationalize their
respective pipelines.

Biotechnology Industry and Virtual Drug Company Growth

The biotechnology industry has grown rapidly over the last 10 years and has
introduced many new developmental drugs. Biotechnology companies do not have the
in-house resources to conduct development and testing. Also, there are several
new pharmaceutical and medical device companies whose business strategy is to
develop a product sufficiently to attract a strategic partner who will
manufacture and market the drug. Many of these virtual drug development
companies with little or no internal resources must outsource drug development
and testing.

Need for Unique Technical Expertise

The increasing complexity of new drugs requires highly specialized quality
and innovative, solution-driven contract research not available in the clients'
labs. The Company believes that this need for unique technical expertise will
increasingly lead to outsourcing of research activity.

Need for Data Management Expertise

Regulatory agencies are requiring more regulatory data and greater access
to that data prior to filing. The FDA is encouraging the use of
computer-assisted filings in an effort to expedite the approval process. Drug
companies are outsourcing to firms with automated data management capabilities.
In response to clients' demands for access to data as it is acquired in the
laboratory, the Company is able to provide clients with remote access to Company
computer systems while at the same time protecting client data from unauthorized
access. The Company has also developed proprietary validated online data entry
software enabling direct publication of data in unique client formats.

Globalization of the Marketplace

A growing number of foreign pharmaceutical companies are seeking US
approval for their products. Foreign firms are relying on independent
development companies with experience in the United States to provide integrated
services through all phases of product development and to assist in preparing
complex and daunting regulatory submissions. Domestic drug firms are broadening
product availability globally, demanding local regulatory approval. The Company
believes that domestic service providers with global reach, established
regulatory expertise and a broad range of integrated development services will
benefit from this trend. The Company has a significant European presence and
domestic skills in foreign operations.

The Company's Role in the Drug Development Process

Process Overview

The Company has 26 years of experience in developing analytical methods to
support drug discovery. Under the United States regulatory system, the
development process for new pharmaceutical products can be divided into three
distinct phases.

1) The preclinical phase includes discovery, characterization, formulation and
safety testing to prepare an Investigational New Drug (IND) exemption for
submission to the FDA. The IND must be accepted by the FDA before the drug
can be tested in humans.

2) The second, clinical phase follows a successful IND submission and further
explores the safety, tolerability, efficacy and dosage of the substance in
humans. Early manufacturing demonstrates production of the substance in
accordance with the FDA's cGMP guidelines. Data from these activities are
compiled in a New Drug Application (NDA), or for biotechnology products a
Product License Application (PLA), for submission to the FDA requesting
approval to market the drug.

3) The third phase follows FDA approval of the NDA or PLA. This includes
production and continued analytical and clinical monitoring of the drug.
The post-approval phase also involves the development and regulatory
approval of product modifications and line extensions, including improved
dosage forms.

The Company's Role

The Preclinical Phase. A new pharmaceutical begins with the synthesis of
new molecules, which may influence a specific target in the disease under study.
These molecules are screened for pharmacological activity using various models.
Once the pharmacologically active molecule is fully characterized, it is
analyzed to confirm its integrity. Development of the initial dosage form for
clinical trials is completed, with analytical chemistry protocols to determine
its stability. Upon successful completion of preclinical safety and efficacy
studies in in vitro and in vivo, an IND submission is prepared and provided to
the FDA for review prior to human clinical trials.

The Company provides its preclinical and bioanalytical services in this
phase. Clients work with the Company's Preclinical Services division to
establish pharmacokinetic and safety testing protocols. These studies range from
acute safety monitoring on drugs and medical devices to chronic, two-year
oncogenicity studies. Bioanalyses of blood sampled under these protocols by the
Company's bioanalytical services group provide kinetic, metabolism and dose
ranging data.

Many of the Company's products are designed for use in preclinical
development. For example:

1) The Company's newest product, the Culex(TM) ABS, a robotic automated blood
sampler, enables researchers to develop pharmacokinetic profiles of drugs
in early screening in rodents quickly and cost effectively. Several
variations on this technology are in development.

2) Company scientists have been recognized by their peers for their
contributions to technology of drugs for central nervous system (CNS)
disorders such as depression, Parkinson's disease, schizophrenia and
Alzheimer's disease. The Company's chromatography products were used to
study serotonin re-uptake inhibitors in the CNS programs at universities
and several major pharmaceutical companies.

3) Company technology is the basis for most of the glucose sensors currently
sold to diabetics, and the majority of firms in this market are Company
clients.

4) The Company's bioanalytical services group used the Company's
chromatography products to develop a single, quick, proprietary method to
screen up to ten therapeutic HIV drugs in the same blood sample with the
cooperation of several major therapeutic drug developers. The method
enables researchers to quantify each component in a drug cocktail or to
monitor HIV treatments.



- 6 -


The Company's ability to solve client problems combining its knowledge
base, services, and products has been a factor in the Company's selection by
major pharmaceutical companies to assist in several preclinical and Phase I, II
and III clinical trials.

The Clinical Phase. After successful submission of an IND application, the
sponsor conducts Phase I human clinical trials in a limited number of healthy
individuals to determine safety and tolerability. This work requires
bioanalytical assays to determine the availability and metabolism of the active
ingredient following administration. Expertise in method development and
validation is essential for this phase, particularly for new chemical entities.
In Phase II clinical trials the drug is administered to individuals who suffer
from the target disease to determine the drug's effectiveness and ideal dose.
When further safety, tolerability and dosing regimens have been established,
Phase III clinical trials with large numbers of patients are conducted to verify
efficacy and safety. After the successful completion of Phase III clinical
trials, the sponsor of the new drug submits an NDA or PLA to the FDA requesting
that the product be approved for marketing.

The Company's bioanalytical work per patient grows rapidly from Phase I
through III. As the number of patients grows the number of samples per patient
declines. Phase II and III studies take several years, practicing well proven
analytical protocols. It is unusual for a sponsor to change laboratories unless
there are problems in the quality or timely delivery of results.

Many patients are receiving multiple drug therapy. The influence of each
drug on the effectiveness of the other drugs must be monitored. These drug
interaction studies often extend clinical trials. A CRO such as the Company can
provide services to several different manufacturers of complementary drugs
simultaneously in cases of potential synergy (e.g. the "cocktail" approach to
HIV therapy). Multi-client studies frequently lead to cost sharing and contacts
with new clients.

The Post-approval Phase. Following approval, the drug manufacturer must
comply with quality assurance and quality control requirements throughout
production and must continue analytical and stability studies of the drug during
commercial production in order to continue to validate production processes and
confirm product shelf life. The drug manufacturer's raw materials must be
analyzed prior to use in production, and samples from each manufactured batch
must be tested prior to release of the batch for distribution to the public. The
Company also provides its bioanalytical services in all areas during the
post-approval phase, concentrating on bio-equivalence studies of new
formulations, line extensions, new disease indications and drug interaction
studies.

Company Services and Products

Overview

The Company provides bioanalytical services, preclinical services and
methods development for the $17 billion per year analytical instrument industry.
The Company has, for 26 years, developed expertise in a number of core
technologies which evolved into state-of-the-art procedures designed to quantify
trace chemicals in complex materials. These technologies include: liquid
chromatography, electrochemistry, solid phase extraction, mass spectrometry,
enzymology and fluorescence detection. The Company also uses its expertise in
analytical chemistry to provide a wide range of bioanalytical services to
pharmaceutical companies, academic institutions and others involved in
pharmaceutical research and development. Preclinical services provide basic
safety and dosage information to researchers and are a source of samples for
bioanalytical analyses.

Services

The Company's customers continue to draw on the Company's knowledge in
bioanalytical chemistry and preclinical services to solve complex problems. The
Company is poised to use its expertise to provide a greater volume and broader
array of services:

o Method Development and Validation. Analytical methods are developed to
demonstrate potency, purity, stability or physical attributes. These
methods are validated to ensure that the data generated are accurate,
precise, reproducible and reliable and are used throughout the drug
development process and in product support testing.

o Product Characterization. Characterization analysis identifies the
chemical composition, structure and physical properties of a compound.
Characterization data is a significant portion of a regulatory
application. The Company uses several techniques to characterize the
compound, including chromatography, spectroscopy, electrochemistry and
other physical chemistry techniques.

o Stability Testing. The Company provides required stability testing and
secure storage facilities necessary to establish and confirm product
purity, potency and other shelf-life characteristics. The Company has
multiple ICH (International Conference on Harmonization) validated
controlled climate GMP facilities.

o Bioanalytical Testing. The Company's bioanalytical testing group
analyzes plasma samples to measure drug concentration and monitor the
rate of absorption and elimination. This is sometimes difficult due to
product metabolism into multiple active and inactive forms.

o Preclinical and Pathology Services. The Company acquired T.P.S., Inc.
in Evansville, Indiana effective October 1, 1999. Renamed BAS
Evansville, this site is the core for the Company's preclinical
services group which provides pharmacokinetic and safety testing
protocols in studies ranging from acute safety monitoring on drugs and
medical devices to chronic, two-year oncogenicity studies.

o Diagnostic Testing. The Company produces fully automated, networkable,
state-of-the-art liquid chromatographs and electrochemical analyzers
based on Windows(R) software. The Company has recently developed and
now produces a line of diagnostic kits designed to fit its
instrumentation. These kits help measure neurotransmitters and their
metabolites and homocysteine, an experimental cardiovascular disease
indicator in plasma and urine.

o In Vivo Sampling. The Company pioneered and has commercialized
miniaturized in vivo sampling products and services for the continuous
monitoring of chemical changes in life. The Company is aggressively
adding new components to this. Target markets include veterinary
research centers, pharmaceutical companies and medical research
centers. The Company has received two significant Phase II SBIR (Small
Business Innovation Research) grants that involve subcontracts with
Purdue University and the University of Kansas for the purpose of
exploring this emerging technology.

Products

The Company designs, manufactures and markets a range of products and
related scientific procedures that detect and quantify the presence of chemicals
in certain substances. The Company's products utilize state-of-the-art
scientific technology including liquid chromatography, electrochemistry and in
vivo sampling instrumentation. Presently, the Company's products and procedures
include:

o The Culex(TM)ABS robotic automatic rodent blood sampling system was
launched in 2000. Pharmaceutical company researchers use the Culex to
monitor drug concentrations as a function of time (pharmacokinetics).
The Culex provides exceptional cost savings, significant reduction in
stress and shorter screening times to drug researchers. Preliminary
sales are exceptional. Culex is promising to be one of the
fastest-growing, most significant products for the Company in a
decade.

o Bioanalytical separation instrumentation (liquid chromatography) and
Windows(R) software detect and quantify low concentrations of
substances in biological fluids and tissues.

o A wide-range of chemical analyzers that use electrochemistry, liquid
chromatography and enzymology analyze trace levels of organic
chemicals such as neurotransmitters in biological samples.


- 8 -


o Diagnostic kits and procedures, designed to add value to the Company's
instrumentation, that enable clinical laboratories and pharmaceutical
researchers to determine the presence of multiple drugs in blood
plasma and to measure neurotransmitters and their metabolites in
plasma and urine. These kits and procedures assist researchers in
developing new drugs for diseases such as AIDS and cardiovascular
disease.

o A line of miniaturized in vivo sampling devices, marketed to
veterinary research centers, pharmaceutical companies and medical
research centers, assist in the study of a number of medical
conditions including stroke, depression, Parkinson's disease, diabetes
and osteoporosis.

Clients

Over the past five years, the Company regularly has provided services and
products to the top 25 pharmaceutical companies in the world, as ranked by 1999
research and development spending. In fiscal 2000, the Company estimates that
more than one-half of its total revenue was derived from these companies. In
fiscal 1999, the Company provided services and products to approximately 300
institutions, including some of the largest United States, European and Japanese
drug companies. Approximately 28% of the Company's revenues are generated from
customers outside the United States.

The Company believes that a concentration of business among certain large
clients is not uncommon in the CRO industry. The Company recognizes, much as
other CROs have recently reported, that concentration of sales among a few large
companies coupled with failure rates of developmental drugs can be a risk for
service providers. The Company redirected its sales team in the middle of FY
2000, to also target pharmaceutical companies with annual revenues less than $1
billion, with the belief that risk could be reduced if distributed over a
broader account base. The company also believes that companies of this size are
less likely to have resources comparable to the Company's and will consequently
be more inclined to establish a consistent, long-term relationship.

Sales and Marketing

Although early client relationships grew primarily through direct, internal
recommendations among major pharmaceutical manufacturers, the current sales and
marketing plan focuses on key account development among the top 200 global
pharmaceutical companies. The Company recognizes that its growth and continued
customer satisfaction depend upon its ability to continually improve its sales
and marketing functions. Team training, merging services and product sales
efforts, and changes to the sales team compensation plan implemented in 2000 are
designed to deliver growth among these target accounts.

In North America, the Company's products are sold directly to the end user.
The Company has 20 personnel selling a range of services and products and an
equal number providing technical and development support. These members are
technically trained and function in both capacities. The Company also has
established a highly professional collection of catalogs, training and technical
support literature, video tapes, CD-Rom presentations, web sites, workshops and
academic publications.

Sales, marketing and technical support are based in the Company's main
office located in West Lafayette, Indiana. The Company also maintains offices in
New Jersey, and Warwickshire and Congleton, UK, each with a sales and technical
staff, enabling the Company to demonstrate its products and present technical
workshops in close proximity to its largest concentration of key customers. The
Company also maintains sales and technical support capabilities in Connecticut,
Massachusetts, New York, Ohio, Texas, Pennsylvania and Kansas.

The Company's primary marketing and sales strategy is to be more
aggressive, to focus on customer needs and to further strengthen communications
with its markets. In doing so, the Company will build on its long history of
innovation and technical excellence.

BAS Evansville, a wholly-owned subsidiary of the Company, provides
preclinical contract research in Mount Vernon, Indiana.

BAS Analytics, Ltd., a wholly-owned subsidiary of the Company, provides
direct liaison with research service clients in the United Kingdom and maintains
a laboratory to provide such services. BAS Instruments, Ltd., also a
wholly-owned subsidiary of the Company, manages most product sales in Europe. In
addition, the Company has a network of more than 20 established distributors
covering Japan, the Pacific Basin, South America, the Middle East, India, South
Africa and Eastern Europe. All of the Company's distributor relationships are
managed from the Company's headquarters in West Lafayette, Indiana.
International growth is planned through acquisitions, stronger local promotion
and significant expansion of the Company's distributor network.

Contractual Arrangements

The Company's service contracts typically establish an estimated fee for
identified services. In most cases, some percentage of the contract costs are
paid in advance. While the Company is performing a contract, clients often
adjust the scope of services to be provided by the Company in light of interim
project results, at which time the fee is adjusted accordingly. Generally, the
Company's fee-for-service contracts are terminable by the client upon written
notice of 30 days or less. 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. The loss of a large contract or the loss of multiple
contracts could adversely affect the Company's future revenue and profitability.

Backlog

Considering that the arrangements, pursuant to which the Company provides
its services, are terminable upon written notice of 30 days or less, the Company
does not calculate backlog for the services it provides and does not believe
that determining such amount would provide a meaningful indicator of the future
performance of its services unit. Backlog for the Company's products consists of
booked purchase orders for products which have not been shipped. The Company
rarely has a backlog for its products of more than one month of sales. Many
products are shipped within 24 hours of receipt of order.

Competition

With respect to its services, the Company competes primarily with in-house
research, development, quality control and other support service departments of
pharmaceutical and biotechnology companies, as well as with university research
laboratories and teaching hospitals. In addition, there are numerous
full-service CRO's that compete in this industry. The largest CRO competitors
offering similar research services include Covance, Inc., Pharmaceutical Product
Development, Inc., Applied Analytical Industries, Inc. and MDS Health Group Ltd.
CROs generally compete on the basis of previous experience, medical and
scientific expertise in specific therapeutic areas, quality of contract
research, ability to organize and manage large-scale trials on a global basis,
medical database management capabilities, ability to provide statistical and
regulatory services, ability to recruit investigators, ability to integrate
information technology with systems to improve the efficiency of contract
research, existence of an international presence with strategically located
facilities, financial viability and price.

- 10 -



With respect to its products, the Company competes with several large
equipment manufacturers, including Agilant, Waters Corporation and Perkin Elmer
Corporation. Competitive factors include product quality, reliability and price.
The Company believes it competes favorably in its target markets because of its
ability to combine quality products with technical assistance and service to
meet customer needs.

Many of the Company's competitors are much larger and have greater
financial resources than the Company. Those resources, much broader product
lines and large, well compensated sales teams make it difficult for the Company
to capture market share from clients other than those who need the Company's
unique capabilities.

Government Regulation

The services performed by the Company are subject to various regulatory
requirements designed to ensure the quality and integrity of pharmaceutical and
diagnostic products. These regulations are governed primarily under the Federal
Food, Drug and Cosmetic Act, as well as associated GLP and GMP regulations which
are administered by the FDA in accordance with current industry standards. The
regulatory requirements apply to all phases of manufacturing, testing and record
keeping, including personnel, facilities, equipment, control of materials,
processes and laboratories, packaging, labeling and distribution. Noncompliance
by the Company with GLP and GMP regulations could result in disqualification of
data collected by the Company in a particular project. Material violation of GLP
or GMP requirements could result in additional regulatory sanctions and, in
severe cases, could also result in a discontinuance of selected Company
operations. Such discontinuance would have a material adverse effect on the
Company's business, financial condition and results of operations.

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 GMP compliance parameters. In addition, FDA regulations and guidelines
serve as a basis for the Company's standard operating procedures where
applicable. Some of the Company's development and testing activities are subject
to the Controlled Substances Act administered by the Drug Enforcement Agency
(DEA), which strictly regulates all narcotic and habit-forming substances. The
Company maintains 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. In addition to FDA regulations, the Company is
subject to other federal and state regulations concerning such matters as
occupational safety and health and protection of the environment.

The Company's activities involve the controlled use of hazardous materials
and chemicals. The Company is subject to foreign, federal, state and local laws
and regulations governing the use, storage, handling and disposal of such
materials and certain waste products. 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.
Such damages could have a material adverse effect on the Company's business and
results of operations.

- 11 -


Product Liability and Insurance

The Company maintains product liability and professional errors and
omissions liability insurance, providing approximately $6.0 million in coverage
on a claims-made basis. Additionally, in certain circumstances the Company seeks
to manage its liability risk through contractual provisions with clients
requiring the Company to be indemnified by the client or covered by clients'
product liability insurance policies. Also, in certain types of engagements the
Company seeks to limit its contractual liability to clients to the amount of
fees received by the Company. The contractual arrangements are subject to
negotiation with clients and the terms and scope of such indemnification,
liability limitation and insurance coverage vary based upon client and project.
Although most of the Company's clients are large, well-capitalized companies,
the financial performance of these indemnities is not secured. Therefore, the
Company bears the risk that the indemnifying party may not have the financial
ability to fulfill its indemnification obligations or that liability would
exceed the amount of applicable insurance. Furthermore, the Company could be
held liable for errors and omissions in connection with the services it
performs. There can be no assurance that the Company's insurance coverage will
be adequate, or that insurance coverage will continue to be available on terms
acceptable to the Company, or that the Company can obtain indemnification
arrangements or otherwise be able to limit its liability risk. Employees

At September 30, 2000, the Company had 230 full-time employees, 144 of
which hold college degrees, including 32 at the doctoral level. All employees
enter into confidentiality agreements intended to protect the Company's
proprietary information. The Company believes that its relations with its
employees are good. None of the Company's employees are represented by a union.
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 skilled personnel is high. The Company believes that its employee
benefit plans enhance employee morale, professional commitment and work
productivity and provide an incentive for employees to remain with the Company.
While the Company has not experienced any unusual problems in attracting or
retaining qualified personnel, there can be no assurance that the Company will
be able to avoid these problems in the future.

Item 2. Properties

The Company's principal executive offices are located at 2701 Kent Avenue,
West Lafayette, Indiana, 47906, and constitute approximately 100,000 square feet
of operational and administrative space. The Company acquired T.P.S., Inc. in
Evansville, Indiana on October 1, 1999. This facility consists of seven
buildings with 50,000 square feet under roof on 50 acres. The Company also
maintains offices which provide sales and technical support services in New
Jersey, Pennsylvania and the United Kingdom, and employs sales and technical
support service representatives in North Carolina, Texas, Connecticut, Maryland
and New Jersey. 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

In April, 1997, CMA Microdialysis Holding A.B. (CMA) filed an action
against the Company in the United States District Court for the District of New
Jersey in which CMA alleged that the Company's microdialysis probes infringe
U.S. Patent No. 4,694,832. Subsequent to September 30, 2000, the Company is
working on a settlement for this infringement case. The Company does not believe
the financial terms of settlement will have a material adverse effect on the
Company's financial condition or its results of operations.

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

The following discussion and analysis should be read in conjunction with
Selected Consolidated Financial Data and the Company's Consolidated Financial
Statements and notes thereto included elsewhere in this Report. In addition to
the historical information contained herein, the discussions in this Report may
contain forward-looking statements that involve risks and uncertainties. The
Company's actual results could differ materially from those discussed herein.

Overview

The Company provides a broad range of value-added services and products
focused on chemical analysis to the worldwide pharmaceutical, medical device and
biotechnology industries. The Company's customer-focused approach and its high
quality services and products enable it to serve as a value-added partner in
solving complex scientific problems by providing cost-effective results to its
customers on an accelerated basis. Founded in 1974 in Lansing, Michigan and
relocated to West Lafayette, Indiana in 1975, the Company has experienced growth
primarily through internal expansion, supplemented by strategic acquisitions. As
part of its internal growth strategy, the Company has developed technical
specialties in such areas as chromatography, electrochemistry, in vivo sampling
and mass spectrometry. The Company's growth has strategically positioned it to
take advantage of globalization in the marketplace and to provide new services
and areas of technical expertise to its customers.

Throughout its history, the Company has taken steps to position itself as a
global leader in the analytical chemistry field. Development of the Company's
infrastructure began in 1975 when it established relationships with several
customers and multiple international distributors. In 1981, the Company
increased its sphere of influence to include Japan with the creation of BAS
Japan, an independent distributor. In 1988, the Company enhanced its computer
software expertise by acquiring Interactive Microware, Inc. in State College,
Pennsylvania. In 1990, the Company began offering contract services to customers
that lacked the time or expertise to perform certain analyses using the
Company's analytical products. In 1995, the Company acquired a distributor, BAS
Instruments Ltd., to further solidify its presence in the United Kingdom. In
1998, the Company acquired a manufacturer of veterinary monitoring and
diagnostic equipment, BAS Vetronics, to provide additional preclinical support.
In 1998, the Company acquired a contract services firm, BAS Analytics Ltd., to
offer local service in the United Kingdom. In 2000, the Company also acquired a
contract services firm, BAS Evansville, to offer preclinical services.

Revenues are derived principally from (i) analytical services provided to
customers and (ii) the sale of the Company's analytical instruments and other
products. Both methods of generating revenue utilize the Company's ability to
identify, isolate and resolve client problems relating to the separation and
quantification of individual substances in complex mixtures. The Company
supports the pharmaceutical industry by focusing on analytical chemistry for
biomedical research, diagnostics, electrochemistry and separations science. The
Company's analytical products are sold primarily to pharmaceutical firms and
research organizations. Principal customers include scientists engaged in drug
metabolism studies, as well as those engaged in basic neuroscience research. The
Company was the first to commercialize the liquid chromatography and
electrochemistry technology which is now the worldwide standard for the
determination of neurotransmitter substances. Research products include in vivo
sampling devices, reagent chemicals, electrochemical apparatus and sensors.

The Company's pharmaceutical service contracts generally have terms ranging
from several weeks to several years. A portion of the contract fee is generally
payable upon acceptance of the agreement with the balance payable in
installments over the life of the contract. The contracts are broken down into
discrete units of deliverable services for which a fixed fee for each unit is
established. Revenue and related direct costs are recognized as specific
contract terms are fulfilled under the percentage of completion method utilizing
units of delivery. The termination of a contract results in no material
adjustments to revenue or direct costs previously recognized. The Company is
entitled to payment for all work performed through the date of notice of
termination and all costs associated with termination of a contract. Revenue
from the sale of the Company's products and the related costs are recognized
upon shipment of the products to customers.

- 15 -


The Company's management believes that fluctuations in the Company's
quarterly results are caused by a number of factors, including the Company's
success in attracting new business, the size and duration of service contracts,
the timing of its clients' decisions to enter into new contracts, the
cancellation or delays of on-going contracts, the timing of acquisitions and
other factors, many of which are beyond the Company's control. In fiscal 2000,
28% of the Company's total revenue was derived from customers located outside
the United States. These markets tend to be much more volatile than the United
States market. Significant governmental, regulatory, political, economic and
cultural issues or changes could adversely affect the growth or profitability of
the Company's business activities in any such market.

Year ended September 30, 2000 compared with Year ended September 30, 1999

Total revenue for the year ended September 30, 2000 decreased 3.2% to $19.2
million from $19.9 million for the year ended September 30, 1999. Service
revenue increased to $11.0 million for the year ended September 30, 2000 from
$10.0 million for the year ended September 30, 1999, primarily as a result of
the addition of preclinical services through the acquisition of T.P.S., Inc.
This increase was more than offset with the decrease in products. Product
revenue decreased to $8.2 million for the year ended September 30, 2000 from
$9.9 million for the year ended September 30, 1999 primarily due to the decrease
in the sales to the Pacific Rim and Europe.

Costs of revenue increased 17.0% to $12.2 million for the year ended
September 30, 2000 from $10.4 million for the year ended September 30, 1999.
This increase of $1.8 million was largely due to costs of services from the
acquisition of Toxicology Pathology Systems. Costs of revenue for the Company's
services increased to 84.1% as a percentage of services revenue for the year
ended September 30, 2000 from 65.0% of services revenue for the year ended
September 30, 1999 due to the addition of costs of services from the acquisition
of T.P.S., Inc. Costs of revenue for the Company's products decreased to 36.2%
as a percentage of product revenue for the year ended September 30, 2000 from
40.0% of product revenue for the year ended September 30, 1999, due primarily to
a change in product mix.

- 16 -


Selling expenses for the year ended September 30, 2000 decreased 13.8% to
$3.4 million from $3.9 million during the year ended September 30, 1999 due to
decreased foreign commission expense. Research and development expenses for the
year ended September 30, 2000 decreased 7.6% to $1.8 million from $2.0 million
for the year ended September 30, 1999 due to the decrease in research grant
activity. General and administrative expenses for the year ended September 30,
2000 increased 17.3% to $3.0 million from $2.6 million for the year ended
September 30, 1999, primarily as a result of the addition of expenses from the
acquisition of T.P.S., Inc.

Other income (expense), net, was $(621,000) in the year ended September 30,
2000 as compared to $(114,000) in the year ended September 30, 1999 as a result
of the increase in interest expense due to increased use of the line of credit.

The Company's effective tax rate for 2000 was 23.8% compared to 32.8% for
fiscal 1999. This decrease was primarily due to nondeductible foreign losses
incurred in fiscal 2000.

Year ended September 30, 1999 compared with Year ended September 30, 1998

Total revenue for the year ended September 30, 1999 increased 8.9% to $19.9
million from $18.2 million for the year ended September 30, 1998. The net
increase of $1.7 million related primarily to increased revenue from services,
which increased to $10.0 million for the year ended September 30, 1999 from $7.6
million for the year ended September 30, 1998 as a result of the expansion of
types and volume of services provided by the Company. During this same period,
product revenue decreased to $9.9 million for the year ended September 30, 1999
from $10.6 million for the year ended September 30, 1998 primarily as a result
of decreased sales in the Asian electrochemistry markets.

Costs of revenue increased 22.7% to $10.4 million for the year ended
September 30, 1999 from $8.5 million for the year ended September 30, 1998. This
increase of $1.9 million was largely due to the addition of a UK services
facility. Costs of revenue for the Company's services increased to 65.0% as a
percentage of services revenue for the year ended September 30, 1999 from 60.4%
of services revenue for the year ended September 30, 1998 due to an increase in
services support staff. Costs of revenue for the Company's products increased to
40.0% as a percentage of product revenue for the year ended September 30, 1999
from 36.8% of product revenue for the year ended September 30, 1998, due
primarily to a change in product mix.

Selling expenses for the year ended September 30, 1999 decreased 12.8% to
$3.9 million from $4.5 million for the year ended September 30, 1998 due to
decreased foreign commission expense. Research and development expenses for the
year ended September 30, 1999 decreased 9.7% to $2.0 million from $2.2 million
for the year ended September 30, 1998 due to the decrease in research grant
activity. General and administrative expenses for the year ended September 30,
1999 increased 9.2% to $2.6 million from $2.3 million for the year ended
September 30, 1998, primarily as a result of an increase in administrative staff
expense and an increase in health care costs.

Other income (expense), net, was $(114,000) in the year ended September 30,
1999 compared to $(25,000) in the year ended September 30, 1998 as a result of
the increase in interest expense due to an increase in long term debt.

The Company's effective tax rate for 1999 was 32.8% compared to 38.2% for
fiscal 1998. This decrease was primarily due to a decrease in nondeductible
foreign losses incurred in fiscal 1999.

Liquidity and Capital Resources

Since its inception, the Company's principal sources of cash have been cash
flow generated from operations and funds received from bank borrowings and other
financings. At September 30, 2000, the Company had cash and cash equivalents of
$478,000, compared to cash and cash equivalents of $1.9 million at September 30,
1999. The decrease in cash resulted primarily from capital expenditures made to
expand the Company's facilities and operations, including the acquisition of
T.P.S., Inc.

The Company's net cash used by operating activities was $539,000 for the
year ended September 30, 2000. Cash used by operations during the year ended
September 30, 2000 consisted of net loss of $1,382,000, less non-cash charges of
$1,448,000, plus a net increase of $605,000 in operating assets and liabilities.
The most significant decrease in operating liabilities related to accounts
payable, which decreased $787,000 at September 30, 2000.

- 17 -


Cash used by investing activities decreased to $2.0 million for the year
ended September 30, 2000 from $4.0 million for the year ended September 30,
1999, primarily as a result of the reduction of Company purchases of laboratory
equipment. Cash provided by financing activities for the year ended September
30, 2000 was $1.1 million due to the increased use of the line of credit offset
by payments on long-term debt.

The Company's net cash provided by operating activities was $1.6 million
for the year ended September 30, 1999. Cash provided by operations during the
year ended September 30, 1999 consisted of net income of $570,000, plus non-cash
charges of $1,321,000, less a net increase of $304,000 in operating assets and
liabilities. The most significant increase in operating assets related to trade
accounts receivable, which increased $638,000 at September 30, 1999.

Cash used by investing activities decreased to $4.0 million for the year
ended September 30, 1999 from $5.0 million for the year ended September 30,
1998, primarily as a result of the Company's completion of construction of
additional facilities. Cash provided by financing activities for the year ended
September 30, 1999 was $3.2 million due to the increase in debt.

Total expenditures by the Company for property and equipment were $1.6
million, $4.1 million and $4.9 million in fiscal 2000, 1999 and 1998,
respectively. Expenditures made in connection with the expansion of the
Company's operating facilities and purchases of laboratory equipment account for
the largest portions of these expenditures. The capital investments relate to
the purchase of additional laboratory equipment corresponding to anticipated
increases in research services to be provided by the Company. The Company
expects to make other investments to expand its operations through internal
growth and strategic acquisitions, alliances and joint ventures. However, the
Company currently has no firm commitments for capital expenditures.

Based on its current business activities, the Company believes that cash
generated from its operations, amounts available under its existing bank line of
credit and credit facility will be sufficient to fund the Company's working
capital and capital expenditure requirements for the foreseeable future.

The Company has a working capital line of credit, which expires April 1,
2001 and allows borrowings of up to $3,500,000. Interest accrues monthly on the
outstanding balance at the bank's prime rate minus 50 basis points (9.0 % at
September 30, 2000) or at the London Interbank Offered Rate (LIBOR) plus 2% as
elected by the Company. The line is collateralized by inventories and accounts
receivable and requires the Company to maintain certain financial ratios. The
balance outstanding on this line of credit at September 30, 2000 was $2.3
million.

On June 24, 1999 the Company obtained a $3,500,000 commercial mortgage with
a bank. The mortgage note requires 59 monthly principal payments of $19,444 plus
interest followed by a final payment for the unpaid principal amount of
$2,352,804 due June 24, 2004. Interest is charged at the one-month LIBOR rate
plus 200 basis points (8.62% at September 30, 2000).

Inflation

The Company believes that inflation has not had a material adverse effect
on its business operations or financial condition.

Bioanalytical Systems, Inc.

Notes to Consolidated Financial Statements

September 30, 2000


1. Significant Accounting Policies

Nature of Business

Bioanalytical Systems, Inc. and its subsidiaries (the Company) engages in
laboratory services, consulting and research related to analytical chemistry and
chemical instrumentation. The Company also manufactures scientific instruments
for use in the determination of trace amounts of organic compounds in
biological, environmental and industrial materials. The Company also sells its
equipment and software for use in industrial, governmental and academic
laboratories. The Company's customers are located in the United States and
throughout the world.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and
its wholly-owned subsidiaries. All significant inter-company accounts and
transactions have been eliminated.

Cash Equivalents

The Company considers all highly liquid investments with an original maturity of
three months or less when purchased to be cash equivalents.

Financial Instruments

Financial instruments that subject the Company to credit risk consist
principally of trade accounts receivable. The Company performs periodic credit
evaluations of its customers' financial condition and generally does not require
collateral on trade accounts receivable.

The Company's cash and cash equivalents, accounts receivable, accounts payable
and certain other accrued liabilities are all short-term in nature and their
carrying amounts approximate fair value. The Company's bank debt has primarily
variable interest rates, thus their carrying amounts approximate fair value.

Inventories

Inventories are stated at the lower of cost or market. Cost is determined using
the last-in, first-out (LIFO) method.

Goodwill

Goodwill represents the excess of cost of acquisitions over the fair value of
net assets acquired and is amortized by the straight-line method over periods
ranging from 15 to 20 years.


- 24 -



Property and Equipment

Property and equipment is recorded at cost, including interest capitalized in
connection with the construction of major facilities. Depreciation, including
amortization on capital leases, is computed using the straight-line method over
the estimated useful lives of 3 through 40 years. Expenditures for maintenance
and repairs are charged to expense as incurred.

Revenue Recognition

The Company's pharmaceutical service contracts generally have terms ranging from
several weeks to several years. The typical contract is six months to one year
in duration. A portion of the contract fee is generally payable upon acceptance
of the agreement with the balance payable in installments over the life of the
contract. A majority of the Company's contracts are broken down into discrete
units of deliverable services for which a fixed fee for each unit is established
and revenue and related direct costs are recognized as units of deliverable
services are fulfilled. For all other service contracts, the Company allocates a
ratable portion of the total contract fee to the units of deliverable services
and recognizes revenue and the related direct costs as the units of deliverable
services are fulfilled. Revenue from the sale of the Company's products and the
related costs are recognized upon shipment of the products to customers.

Advertising Expense

The Company expenses advertising costs as incurred. Advertising expense was
$306,737, $308,831 and $551,848 for 2000, 1999 and 1998, respectively.

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 financial statements and accompanying notes.
Actual results could differ from those estimates.

Stock Options

In accordance with Statement of Financial Accounting Standards No. 123 (SFAS No.
123), "Accounting for Stock-Based Compensation," the Company uses the intrinsic
value method to account for stock options, consistent with the existing rules
established by Accounting Principles Board No. 25, "Accounting for Stock Issued
to Employees."

- 25 -



2. Earnings Per Share

Basic earnings per share is computed on the basis of the weighted average number
of common shares outstanding. Diluted earnings per share is computed on the
basis of the weighted average number of common and common equivalent shares
outstanding. Common equivalent shares include the dilutive effect of employee
and director options to purchase common shares and convertible preferred shares,
which are assumed to be converted. There was no dilutive effect of employee and
director options to purchase common shares for fiscal year 2000. The dilutive
effect of employee and director options to purchase common shares was to
increase the weighted average number of common shares outstanding by 170,031 and
172,382 shares in 1999 and 1998, respectively. The dilutive effect of
convertible preferred shares was to increase the weighted average number of
common shares outstanding by 113,285 shares in 1998.

3. Acquisitions

Effective October 31, 1997 the Company acquired all of the capital stock of
Vetronics Inc., for cash approximating $200,000 and a $150,000 note payable. The
acquired business was involved in the distribution of veterinary equipment and
supplies in the United States.

Effective July 1, 1998 the Company acquired all of the capital stock of Clinical
Innovations Ltd., for cash approximating $1,500,000. The acquired business was
involved in the processing of bioanalytical samples for pharmaceutical firms in
the United Kingdom.

Effective October 1, 1999, the Company acquired all of the capital stock of
T.P.S., Inc. for cash approximating $400,000 and $740,000 in assumption of debt.
The acquired business was involved in providing preclinical services to the
pharmaceutical industry.

All acquisitions were accounted for using the purchase method of accounting and
the results of operations have been included in the consolidated financial
statements since the effective dates of acquisition. The purchase prices were
allocated to the net assets acquired, including $956,000 to goodwill, based upon
the fair market value at the date of acquisitions.

On an unaudited pro forma basis, revenue, net income and net income per common
share (diluted) for the years ended September 30, 1999 and 1998 were
$21,790,000, $194,000, $0.04 and $22,284,000, $782,000, $0.18, respectively.
This pro forma data presents the consolidated results of operations as if the
acquisitions had occurred on October 1, 1997, after giving effect to certain
adjustments, including amortization of goodwill, increased interest expense and
related income tax effects.

The pro forma results have been prepared for comparative purposes only and do
not purport to indicate the results of operations which would actually have
occurred had the acquisition been in effect on the date indicated, or which may
occur in the future.

Pro forma amounts for the years ended September 30, 1998 include, for certain of
the acquired entities, financial data for the years ended February 28 and
December 31, respectively, as it was not practicable to determine the September
30 year end results.

5. Debt Arrangements

The Company has a working capital line of credit, which expires April 1, 2001
and allows borrowings of up to $3,500,000. Interest accrues monthly on the
outstanding balance at the bank's prime rate minus 50 basis points (9.0 % at
September 30, 2000) or at the London Interbank Offered Rate (LIBOR) plus 2% as
elected by the Company. The line is collateralized by inventories and accounts
receivable and requires the Company to maintain certain financial ratios. The
balance outstanding on this line of credit at September 30, 2000 was $2,267,281.

On June 24, 1999 the Company obtained a $3,500,000 commercial mortgage with a
bank. The mortgage note requires 59 monthly principal payments of $19,444 plus
interest followed by a final payment for the unpaid principal amount of
$2,352,804 due June 24, 2004. Interest is charged at the one-month LIBOR rate
plus 200 basis points (8.62% at September 30, 2000).

Cash interest payments of $498,513, $287,058 and $260,249 were made in 2000,
1999 and 1998, respectively. Cash interest payments for 1999 and 1998 included
interest of $64,833 and $127,077, respectively, which was capitalized. These
amounts included interest required to be paid on a portion of the undistributed
earnings of a subsidiary which qualifies as a domestic international sales
corporation.

Disclosure of pro forma information regarding net income and earnings per share
is required by SFAS No. 123 as if the Company has accounted for its employee
stock options granted subsequent to December 31, 1994, under the fair value
method as defined by that Statement. The fair value for options granted by the
Company was estimated at the date of grant using a Black-Scholes option pricing
model with the following weighted-average assumptions:


Risk-free interest rate 5.50%
Dividend yield 0.00%
Volatility factor of the expected market
price of the Company's common stock .53 (.43 in 1999:
.52 in 1998)
Expected life of the options (years) 7.0

The Black-Scholes option valuation model was developed for use in estimating the
fair value of traded options which have no vesting restrictions and are fully
transferable. In addition, option valuation models require the input of highly
subjective assumptions including expected stock price volatility. Because the
Company's employee stock options have characteristics significantly different
from those of traded options, and because changes in the subjective input
assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its employee stock options.

- 32 -


For purposes of pro forma disclosures, the estimated fair value of the options
are amortized to expense over the related vesting period. Because compensation
expense is recognized over the vesting period, the initial impact on pro forma
net income may not be representative of compensation expense in future years,
when the effect of amortization of multiple awards would be reflected in the
consolidated statements of operations. The Company's pro forma information
giving effect to the estimated compensation expense related to stock options is
as follows:



2000 1999 1998
---- ---- ----

Pro forma net income (loss) $(1,415,284) $504,268 $367,190
Pro forma net income (loss) per share $ (0.31) $ 0.11 $ 0.08




The weighted average fair value of options granted during the year was $1.64,
$2.29 and $4.77 in 2000, 1999 and 1998, respectively.

9. Retirement Plan

Effective July 1, 1984, the Company established an Internal Revenue Code Section
401(k) Retirement Plan (the Plan) covering all employees over twenty-one years
of age with at least one year of service. Under the terms of the Plan, the
Company contributes 2% of each participant's total wages to the Plan. The Plan
also includes provisions for various contributions which may be instituted at
the discretion of the Board of Directors. The contribution made by the
participant may not exceed 18% of the participant's annual wages. The Company
made no discretionary contributions under the Plan in 2000, 1999, and 1998.
Contribution expense was, $256,107, $227,022 and $187,896 in 2000, 1999 and
1998, respectively.

11. Litigation

In April 1997, CMA Microdialysis Holding A.B. (CMA) filed an action against the
Company in the United States District Court for the District of New Jersey in
which CMA alleged that the Company's microdialysis probes infringe U.S. Patent
No. 4,693,832. Subsequent to September 30, 2000, the Company is working on a
settlement for this infringement case. The Company does not believe that the
financial terms of settlement will have a material adverse effect on the
Company's financial condition or its results of operations.
