                                     PART I

ITEM 1.  BUSINESS
- - -------  --------

                                     GENERAL

        Chrysalis International Corporation, a Delaware corporation (the
"Company" or "Chrysalis"), is an international contract research organization
("CRO") providing a broad portfolio of integrated drug development services
primarily to the pharmaceutical and biotechnology industries. This portfolio of
drug development services includes preclinical and clinical capabilities that
enable the Company to manage a comprehensive drug development program or a
client's specific requirements. The Company utilizes its international
expertise and experience in preclinical and clinical services to provide a
coordinated approach for a client to transition its drug through various
preclinical to clinical stages of development thereby minimizing certain delays
which typically occur before a new drug is introduced to the market. In
addition, the Company is the only CRO that is currently able to use its
proprietary transgenic and other related technology to provide services for its
clients that require transgenic animal models for the evaluation of therapeutic
lead compounds for further development and for genomics research in order to
determine the function of human genes and identify gene targets implicated in
disease. The Company generates substantially all of its revenues from its drug
development services and provides services for more than 250 clients in 26
countries.

         On December 18, 1996, the Company issued 2,632,600 shares of Common
Stock in connection with the acquisition (the "Acquisition") by the Company of
all of the outstanding capital stock of, or equity interests in, BioClin, Inc.,
a Delaware corporation, BioClin Europe AG, a Swiss corporation, BioClin GmbH, a
German corporation, Kilmer N.V., a Netherlands Antilles corporation, and BioClin
Institute of Clinical Pharmacology GmbH, a German corporation (collectively, the
"BioClin Group"). The Acquisition is being recorded using the
"pooling-of-interests" method of accounting.

         Chrysalis is also the exclusive commercial licensee of a U.S. patent
covering Pronuclear DNA Microinjection ("DNA Microinjection"), the process
widely used in the pharmaceutical and biotechnology industries to develop
transgenic animals. The Company utilizes this license for its drug development
services and grants sublicenses for the use of this technology. These
sublicenses entitle the Company to receive revenues consisting of fees and, in
certain cases, royalties.

         The Company was incorporated in 1988.

NEW DRUG DEVELOPMENT PROCESS OVERVIEW

         Drug development is an expensive and lengthy process. Before a new drug
can be marketed, it must undergo extensive testing and regulatory review to
determine its safety and efficacy. This process consists of many stages -- two
of the most critical being preclinical and clinical testing. In preclinical
testing, the sponsor of the new drug conducts laboratory analyses and animal
tests to determine the basic biological activity and safety of the drug. After
successfully completing the preclinical phase, the drug undergoes a series of
clinical tests in 






                                        2

humans, typically progressing from dosing studies in healthy volunteers to
testing in patients with the targeted disease. The information generated during
these trials is critical for gaining marketing approval from the United States
Food and Drug Administration (the "FDA") or other regulatory agencies. In the
United States, preclinical and clinical testing must comply with the
requirements of Good Laboratory Practices ("GLP") and Good Clinical Practices
("GCP") and other standards promulgated by the FDA and other federal and state
governmental authorities.

         The FDA pioneered the use of clinical trials for new drug development,
and the agency's approval process has shaped much of drug regulation worldwide.
In recent years, the FDA and corresponding regulatory agencies of the major
industrial countries, including Canada, Japan and the European Union (the "EU"),
commenced discussions to develop common standards for both the conduct of
preclinical and clinical studies and the format and content of applications for
new drug approvals. Data from multi-national studies adhering to GCP are now
generally acceptable to the FDA and the governments within the EU.

         In the United States, a drug sponsor must file an Investigational New
Drug Application (the "IND") with the FDA before the commencement of human
testing of a drug. The IND includes preclinical testing results and sets forth
the sponsor's plans for conducting human clinical trials. The design of these
plans, known as the study protocol, is critical to the success of the drug
development effort because the protocol must correctly anticipate the data and
results that the FDA will require before approving the drug.

         Extensive preclinical testing, involving pharmacology and toxicology
studies, is required before a drug developer may obtain permission to conduct
safety and efficacy testing in humans. In efficacy studies, drug candidates are
evaluated by administering them to animal models that simulate human disease
conditions. Such screens are used primarily by pharmaceutical and biotechnology
companies. In toxicology studies, drug candidates are tested in normal, healthy
animals to determine their potential toxicity to humans. In addition, new
industrial and agricultural chemicals often require extensive toxicology testing
before they may be sold. Consequently, toxicology tests are used not only by
developers of new drugs, but also by developers of other chemical products.

         Human trials usually start on a small scale to assess safety and then
expand to test efficacy. Trials are usually grouped into four phases, with
multiple trials generally conducted within each phase. Clinical trials often
represent the most expensive and time-consuming part of the overall drug
development process. The information generated during these trials is critical
for gaining marketing approval from the FDA or other regulatory agencies.

         Phase I. Phase I trials are conducted on healthy volunteers, typically
20 to 80 persons, to develop basic safety data relating to toxicity, metabolism,
absorption, elimination and other pharmacological actions.

         Phase II. Phase II trials are conducted on a small number of subjects,
typically 100 to 200 patients, who suffer from the drug's targeted disease or
condition. Phase II trials offer the first evidence of clinical efficacy, as
well as additional safety data.

                                

                                        3


<PAGE>   4



         Phase III. Phase III trials are conducted on a significantly larger
population of several hundred to several thousand patients who suffer from the
targeted disease or condition. Phase III trials are designed to measure efficacy
on a large scale as well as long-term side effects.

         Phase IV. As a condition of granting marketing approval, the FDA may
require that a sponsor continue to conduct additional clinical trials, known as
Phase IV trials, to monitor long-term risks and benefits, study different dosage
levels, or evaluate different safety and efficacy parameters in target patient
populations. With the increasing importance of Phase IV trials has also come
increased complexity in the scope of the trials (i.e., the number of patients
tested) and the manner in which they are conducted (i.e., the number of sites at
which testing is performed).

         After the successful completion of Phase III trials, the sponsor of a
new drug may submit a New Drug Application ("NDA") to the FDA. The NDA is a
comprehensive filing that includes, among other things, the results of all
preclinical and clinical studies, information about the drug's composition and
the sponsor's plans for producing, packaging and labeling the drug. Most of the
clinical data contained in an NDA is generated during the Phase II and III
trials. Drugs that successfully complete FDA review may be marketed in the
United States, subject to the conditions imposed by the FDA in its approval.

INDUSTRY OVERVIEW

         The CRO industry provides independent product development services
primarily for the pharmaceutical and biotechnology industries. Companies in
these industries outsource product development services to CROs in order to
manage the drug development process more efficiently and cost-effectively to
maximize the benefits in time and profit of patent-protected products. CROs
derive substantially all of their revenue from the research and development
expenditures of pharmaceutical and biotechnology companies. The CRO industry has
evolved from providing primarily preclinical services in the 1970s to a
full-service industry, offering services during the preclinical and clinical
phases of development for new drugs. In addition to managing clinical trials,
CROs may also provide scientific evaluations and analyze the results according
to good clinical and laboratory practices as required by applicable regulatory
authorities.

         The CRO industry is highly fragmented, with participants ranging from
several hundred small, limited-service providers to a few large, full-service
CROs with global capabilities. Although there are few barriers to entry for
small, limited-service providers, the Company believes that there are
significant barriers to becoming a full-service CRO with global capabilities.
Some of these barriers include the infrastructure necessary to serve the global
needs of clients, the high fixed personnel costs required to develop broad
therapeutic capabilities, the expertise and infrastructure necessary to provide
general and specialty preclinical services, the ability to access investigators
and specific patient populations in sufficient numbers, and the need for
sophisticated management information systems, expertise and technology to manage
complex clinical trials.

         As a result of competitive pressures and economies of scale, the CRO
industry is consolidating. Mergers and acquisitions have resulted in the
emergence of a few full-service

                                

                                        4


<PAGE>   5



CROs with the international technical and financial resources to conduct all
phases of preclinical and clinical drug development trials on behalf of
pharmaceutical and biotechnology companies. The Company believes that industry
trends favor those CROs able to provide a full range of services.

TRENDS AFFECTING THE CRO INDUSTRY

         The Company believes that certain industry trends will continue to
increase the need for pharmaceutical and biotechnology companies to outsource
their drug development requirements. These trends include: (i) the desire of
many pharmaceutical companies to respond to cost containment pressures and
reduce the high fixed costs associated with drug development by relying on the
combination of internal resources and CROs; (ii) the attempt by pharmaceutical
and biotechnology companies to outsource drug development to CROs with global
capabilities to maximize profits from a given drug by pursuing regulatory
approvals in multiple countries simultaneously; (iii) the maturation of the
biotechnology industry and the resulting increase in the demand for expertise
and services provided by outside sources, including CROs; (iv) the desire by
pharmaceutical and biotechnology companies to reduce the time required to
develop and bring a new drug to market by outsourcing preclinical and clinical
trials to CROs that provide a full range of services; (vi) increasingly complex
and stringent regulatory requirements on a global basis, together with recent
efforts to develop global harmonized regulatory standards, escalate the demands
on data collection and analysis which prompts outsourcing to CROs with global
data management expertise; (vi) the escalation of worldwide research and
development expenditures for new drugs, including amounts spent on services of
the type provided by CROs, resulting from pressures to develop new drugs for the
treatment of chronic disorders and life- threatening diseases; (vii) the efforts
by pharmaceutical companies to reserve their internal resources for the
development of new drugs by using CROs to manage and conduct preclinical and
clinical trials; and (viii) the growth by pharmaceutical and biotechnology
companies in the area of genomics research in order to determine the function of
human genes and identify gene targets implicated in disease.

         In response to these trends, the CRO industry has begun to experience
consolidation, including the formation of strategic alliances. Pharmaceutical
companies have begun to utilize a smaller pool of CROs and have sought to
transform their contractual relationships with CROs from "vendor" to "strategic
partner." Biotechnology companies have also begun to take a more global,
long-term perspective on their CRO contracting activities.

BUSINESS STRATEGY

         The Company follows a strategy to focus on these industry trends. The
primary components of this strategy include: (i) the utilization of a broad
range of services enabling clients to use the preclinical through clinical drug
development services provided by the Company on an international basis; (ii) a
coordinated approach for a client to transition its drug through various
preclinical to clinical stages of development thereby minimizing certain delays
which typically occur before a new drug is introduced to the market; (iii) the
use of preclinical services to establish early relationships with clients and
the leveraging of its existing preclinical client base to utilize the Company's
broad range of drug development services, in particular,

                                

                                        5


<PAGE>   6



drug development services relating to Phase I through Phase IV trials; (iv) the
continued investment of resources in the Company's specialty preclinical
services such as continuous infusion techniques and transgenic technology; (v)
the expansion, through selective acquisition or internal growth, into new
geographic areas and enhanced therapeutic specialization and complementary
businesses; (v) the utilization of transgenic animal technology to provide
services to the genomics industry; and (vii) the continuation of investment in
and utilization of information and data management technology.

                                    SERVICES

         The Company provides a broad portfolio of drug development services.
The major categories of services offered by the Company are as follows:

PRECLINICAL SERVICES.

         The Company believes it offers clients, on a worldwide basis, a broad
range of preclinical drug development services and can provide a majority of the
preclinical testing requirements necessary to secure FDA (U.S.), EC (Europe) and
MHW (Japan) approval to initiate human clinical trials. The Company provides the
following preclinical drug development services:

         Toxicology. Toxicology studies are designed to identify and evaluate
any harmful effects that pharmaceuticals or chemicals might cause to humans.
These studies are required in connection with the FDA approval process. The
Company provides the following toxicology testing services: mutagenesis/genetic
toxicology; teratology; reproduction/fertility; immunotoxicology; continuous
infusion; carcinogenesis; and acute, sub-acute and chronic evaluations. The
Company believes it has a recognized specialty expertise in continuous infusion
administration techniques and immunotoxicology.

         Pharmacology. Pharmacology studies are designed to quantify the
properties and reactions of drugs primarily in relation to their therapeutic
value. The Company provides testing in the following therapeutic areas: central
nervous system; cardiovascular; pulmonary; anti-inflammatory; gastrointestinal;
cardiopulmonary; and analgesia. In addition, the Company provides safety
pharmacology studies, which include the evaluation of possible effects on the
central nervous system, cardiovascular, gastrointestinal, pulmonary and renal
function as well as adverse interaction with drugs likely to be co-administered
with the development candidate.

         Pharmacokinetics. Pharmacokinetic studies are designed to characterize
the time course of drug absorption, distribution, metabolism and excretion and
relate these processes to the intensity and time course of pharmacological and
toxicological effects of drugs.

         Immunology. Immunology studies are designed to evaluate and test the
immunoregulatory potential of substances.

                                

                                        6

TRANSGENIC SERVICES.

         The Company has observed an acceptance by the pharmaceutical and
biotechnology industries in the use of transgenic laboratory animal model
technology as a tool to improve drug discovery programs. This acceptance,
together with the Company's scientific experience and proprietary DNA
Microinjection technology, provides the Company with the opportunity to offer
its portfolio of specialty transgenic-based contract research services for those
companies electing to outsource all or a portion of their transgenic animal
requirements. These transgenic-based specialty contract research services
include custom model development programs, molecular biology services, gene
function assessment, and other related services.

         In the area of genomics research, the Company's transgenic animal
technology is being used to determine the functions of human genes and to
identify human gene targets implicated in disease. Transgenic animal technology
provides for the genetic manipulation of animals, allowing for the production of
animals that more accurately reflect human biochemistry, physiology and
pathology. Coupled with the identification of new genes, resulting from
worldwide efforts to map and sequence the human genome, transgenic animal
technology allows for the generation of new laboratory animals with specifically
engineered genetic traits. These new animals will facilitate the understanding
of the molecular basis of disease progression which may lead to the
identification of new pharmacological approaches and improved animal models for
evaluating new pharmaceutical therapies. By identifying more specific
pharmaceutical targets and providing more informative preclinical data on
experimental compounds, these genetically modified animals may have the
potential to reduce the time to bring new pharmaceutical therapies to market.

CLINICAL SERVICES.

         The Company's clinical services include clinical trial management
services, clinical data management and biostatistical services, and product
registration and regulatory services. These services can be provided separately
or as an integrated package. Services from each of these categories can be
utilized for the development and execution of an NDA.

         Clinical Trial Management Services. The Company offers complete
services for the design, placement, performance and management of clinical trial
programs, critical elements in obtaining regulatory approval for drugs. The
Company has performed services in connection with trials in many therapeutic
areas. The Company's multi-disciplinary clinical trials group has the ability to
examine a product's existing preclinical and clinical data for the purposes of
designing protocols for clinical trials in order to ascertain evidence of the
product's safety and efficacy.

         The Company's services include management of Phase I through IV trials,
including design of operations manuals, identification and recruitment of trial
investigators, initiation of sites, monitoring for strict adherence to GCP, site
visits to ensure compliance with protocol procedures and proper collection of
data, interpretation of trial results and report preparation. Many of the
Company's current projects involve Phase II, III or IV clinical trials, which,
in most cases, are significantly larger and more complex than Phase I trials.

                                

                                        7


<PAGE>   8




         Phase I Services. The Company provides a number of specialized Phase I
services. They include: computerized volunteer databases; a clinical
pharmacology unit; access to special populations; vital signs; telemetry; and
statistical evaluation. Phase I trials are conducted on healthy volunteers,
typically 20 to 80 persons, to develop basic safety data relating to toxicity,
metabolism, absorption, elimination and other pharmacological actions.

         Tolerability pharmacokinetic and pharmacodynamic investigations and
drug-drug interaction studies can be performed in young and elderly healthy
volunteers, as well as in special populations, including patients with renal or
hepatic impairment. The Company has access to a large population of suitable and
reliable volunteers, and, since its opening, has built up an active panel of
approximately 2,000 volunteers which is continually reviewed and expanded.

         The Company's Phase I capability complements its European and North
American clinical operations for Phase II to IV trials. This network of clinical
facilities allows parallel, worldwide development of pharmaceutical products.

         Phase II--Phase IV Services. The Company provides Phase II through
Phase IV services, including efficacy testing, additional safety data, long-term
risks and side effects and other matters. The Company maintains a network of
physicians who serve as investigators, hospitals and university centers for
in-and-out-patient studies, established research sites performing special
investigations and a selection of centralized laboratories in each country
across Europe, Israel, and North America. In connection with Phase II through
Phase IV services, the Company provides project management, traditional
monitoring or monitoring by fax or remote/direct data entry and data management.

         One recent development in the CRO industry is the emergence of trials
involving tests on over 1,000 patients over a period of several years at
multiple sites. These large multiple site trials have resulted from the drug
companies' emphasis on treating and curing chronic disorders and the resulting
need to thoroughly test large numbers of patients for long-term side effects of
new drugs. The Company is conducting large multiple site trials and actively
markets its capabilities in this area.

         Monitoring for strict adherence to GCP. Efficient data collection, form
design, detailed operations manuals and site visits by the Company's clinical
research associates ("CRAs") are utilized to determine whether clinical
investigators and their staffs follow established protocols and accurately
record the findings of the trials. In addition, the Company has quality
assurance auditors that provide additional internal and external auditing.

         In connection with its services, the Company assists clients with one
or more of the following:

         (i) Study Protocol. The protocol defines the medical issues the study
seeks to examine and the statistical tests to be conducted such as the frequency
and type of laboratory and clinical measures that are to be tracked and
analyzed, the number of patients required to produce a

                                

                                        8


<PAGE>   9



statistically valid result, the period of time over which they must be tracked
and the frequency and dosage of drug administration.

         (ii) Case Report Forms. Once the study protocol has been finalized,
special forms for recording the required information must be developed. These
forms are called Case Report Forms ("CRFs").

         (iii) Site and Investigator Recruitment. The drug is administered to
patients under the supervision of physicians who serve as investigators, at
hospitals, clinics or other locations, referred to as sites. Potential
investigators may be identified by the drug sponsor or the Company, which then
solicits the investigators' participation in the study. Generally, the
investigators contract directly with the Company. The trial's success depends on
the successful identification and recruitment of investigators with proper
expertise and an adequate base of patients who satisfy the requirements of the
study protocol. The Company maintains a network of investigators who have
conducted clinical trials.

         (iv) Patient Recruitment and Enrollment. The Company recruits Phase I
volunteers and maintains a database of such volunteers. The investigators,
however, find and enroll patients suitable for the Phase II through IV trials
according to the study protocol. Prospective patients are required to review
information about the drug and its possible side effects and sign an informed
consent to record their knowledge and acceptance of potential side effects.
Patients also undergo a medical examination to determine whether they meet the
requirements of the study protocol. Patients then receive the drug and are
examined by the investigator as specified by the study protocol.

         (v) Study Monitoring and Data Collection. As patients are examined and
tests are conducted in accordance with the study protocol, data are recorded on
CRFs and laboratory reports. The data are collected from study sites by CRAs.
CRAs visit sites regularly to ensure that the CRFs are completed correctly and
that all data specified in the protocol are collected. CRFs are reviewed for
consistency and accuracy before their data are entered into an electronic
database.

         (vi) Medical Affairs. Throughout the course of a clinical trial, the
Company may provide various medical research and services, including medical
monitoring of clinical trials, interpretation of clinical trial results and
preparation of clinical study reports.

         (vii) Report Writing. The results of statistical analysis of data
collected during the trial, together with other clinical data, are included in a
final report generated for inclusion in a regulatory document.

         (viii) Information Technology. A fully networked information system is
available to facilitate complete computerized data management of Phase I through
IV trials. Data capture for Phase I is maintained by direct CRF "bedside" entry
of primary data and the creation of the electronic CRF. Data collected in CRFs
is entered into the study database within 72 hours of collection. Laboratory
data is on-line for review by physicians and project managers.

                                

                                        9


<PAGE>   10



         For Phase II through IV trials, monitored CRF pages are forwarded to
the Company's two data management centers (Dusseldorf, Germany and Austin,
Texas) for double data entry. Query lists are generated and returned to the
monitors for resolution. Alternatively, the Company offers the Almedica Fax
MonitoringTM system whereby completed CRF pages are transmitted from the sites
directly to either of the Company's two data management centers.

         Clinical Data Management and Biostatistical Services. The Company has
experience in the creation of scientific databases for all phases of the drug
development process. These databases provide clients with data abstraction, data
review and coding, data verification and editing and problem data resolution
capabilities. The Company utilizes an imaging technology process which
eliminates time and minimizes potential data entry errors by electronically
routing, tracking and querying optically scanned CRFs. The Company's data
management professionals assist in the design and development of study protocols
and CRFs, training manuals and training sessions for investigators and
coordinators.

         The Company's biostatistics professionals provide biostatistical
consulting, database design, data analysis and statistical reporting. The
Company's biostatisticians provide clients with assistance in all phases of drug
development. These professionals develop and review protocols, design
appropriate analysis plans and design report formats to address the objectives
of the study protocol, as well as the client's individual objectives.

         The Company believes that its data management and biostatistical
services capabilities can be utilized by a client more effectively when packaged
as part of its total clinical trials management services in the conduct of
Phases I through Phase IV trials. This packaging permits a faster and less
costly clinical trial process, as the data are collected and analyzed more
rapidly and the decision to move to the next phase can be made more quickly.
Although the Company believes that many pharmaceutical companies treat each
phase as a distinct trial, the Company emphasizes this packaged approach as an
integrated process.

         Product Registration Services/Regulatory Affairs. The pharmaceutical
companies who are clients of the Company have their own regulatory expertise and
generally register their products without the assistance of third parties. In
connection with its Phase I through IV services to these pharmaceutical
companies, the Company provides regulatory strategy formulation, consultation
and, if requested, acts as a liaison with the FDA and other international
regulatory agencies.

         The Company intends to market its clinical testing services to
biotechnology companies which may not have experience or expertise in regulatory
and product registration matters. As part of its clinical trial services, the
Company offers these clients comprehensive product registration services,
document preparation, regulatory strategy formulation and compliance, and may
act as liaison with the FDA and other international regulatory agencies.

         Although to date the revenues from these services to biotechnology
companies have not been material, the Company believes it necessary to offer
these services to be competitive in the CRO industry. As a result, the Company's
regulatory affairs experts review existing published literature, assess the
scientific background of a product, assess the competitive and regulatory

environment, identify deficiencies and define the steps necessary to obtain
registration in the most expeditious manner. Through this service, the Company
may assist its clients to determine the feasibility of developing a particular
product or product line.

         The Company's regulatory affairs professionals have experience in the
analysis, preparation and submission of FDA regulatory documents covering a wide
range of products, including prescription and over-the-counter drugs. The
Company also has experience with preparing regulatory documentation for
submission to European regulatory authorities.

                         MICROINJECTION PATENT LICENSING

         The Company grants sublicenses of its proprietary DNA Microinjection
technology, the process widely used in the pharmaceutical and biotechnology
industries to develop transgenic animals. These sublicenses entitle the Company
to receive revenues consisting of fees and, in certain cases, royalties.

         While the Company has retained the exclusive rights to use DNA
Microinjection for its drug development services, it has granted several
non-exclusive sublicenses for the use of DNA Microinjection in a variety of
applications, including the development, use and sale of other commercial
transgenic animal-based products and transgenic animal models. In those certain
instances where the Company grants a sublicense for commercial applications,
such as the use of a transgenic animal to produce therapeutic proteins, the
Company receives an annual license fee and revenue based royalties upon
commercialization of the transgenic animal-based products and services. In the
case of sublicenses for noncommercial applications, such as the use of
transgenic technology for basic in-house research purposes, the Company
generally receives an annual license fee. The Company will continue to license
this technology for the development of transgenic animals and transgenic animal
derived products which do not conflict with the specialty transgenic animal
services offered by the Company.

                                    MARKETING

         Prior to the Acquisition, the majority of new preclinical studies
conducted by the Company were derived from existing clients. To obtain new
clients, the Company contacted potential clients directly through its
representatives and indirectly by mailings as well as participating at various
scientific association symposia. Further, the Company's sales and marketing
department targeted the promotion of its preclinical drug development services
to potential new clients who were not familiar with the Company's services, and
the expansion of services for existing clients. In addition, the Company's
scientific personnel participated in a variety of endeavors such as publishing
scientific papers and making presentations at scientific meetings. The Company
also participated in commercial conferences and advertised in scientific
journals and trade publications.

         In addition, prior to the Acquisition, clinical marketing activities
were conducted primarily by the Company's senior operational personnel. In
response to the highly technical

                                

                                       11


<PAGE>   12



nature of the Company's business, most of the personnel had scientific
backgrounds. Additionally, the Company advertised in trade journals and
publications and, from time to time, used direct mailings of information to
existing and potential clients. The Company also attended and provided exhibits
at selected trade shows in the United States and Europe.

         During fiscal 1996, the Company added business development personnel
for both its preclinical and clinical businesses. As a result of the
Acquisition, the Company currently coordinates its marketing efforts for its
broad range of services through a central business development function, which
includes the involvement of senior operational personnel in this effort. The
Company's marketing personnel seek new clients, seek contracts with new
therapeutic areas or divisions with existing clients, cross-sell other services
to existing clients and develop strategic alliances with major pharmaceutical
and biotechnology companies. The Company continues to advertise in trade
publications and through direct mailings and provide exhibits at selected trade
shows. Also, the Company's professionals continue to publish in scientific
journals and trade publications and make presentations at scientific meetings
and commercial conferences.

                            CONTRACTUAL ARRANGEMENTS

         Most of the Company's contracts are fixed priced contracts that require
a portion of the contract amount to be paid at or near the time the trial is
initiated. The Company generally bills its clients upon the completion of
negotiated performance requirements and, to a lesser extent, on a date certain
basis. Certain of the Company's contracts are subject to cost limitations which
cannot be exceeded without client approval. Because, in many cases, the Company
bears the risk of cost overruns, unbudgeted costs in connection with performing
these contracts may have a detrimental effect on the financial results of the
Company. If it is determined that a loss will result from the performance of a
contract, the entire amount of the estimated loss is charged against income in
the period in which the determination is made.

         The Company's contracts generally may be terminated with or without
cause. In the event of termination, the Company is typically entitled to all
sums owed for work performed through the notice of termination and all costs
associated with termination of the study. Once a trial has been commenced,
change orders may be requested by clients based on the results of the trial to
date, including changes in the scope of the trial and in the services to be
provided by the Company. Accordingly, compensation under a contract may increase
or decrease during the duration of a contract. In addition, some of the
Company's contracts provide for an early termination fee, the amount of which
usually declines as the trial progresses. The loss of a large contract or the
loss of multiple contracts, however, could adversely affect the Company's future
revenues and profitability. In addition, termination or delay in the performance
of a contract occurs for various reasons, including, but not limited to,
unexpected or undesired results, inadequate patient enrollment or investigator
recruitment, production problems resulting in shortages of the drug being
tested, adverse patient reactions to the drug being tested, or the client's
decision to de-emphasize a particular trial.

                                

                                       12


<PAGE>   13



                                    CUSTOMERS

        The Company has in the past derived, and may in the future derive, a
significant portion of its net service revenue from a relatively limited number
of major projects or clients. Concentrations of business in the CRO industry
are not uncommon and are increasing as large pharmaceutical and biotechnology
companies are outsourcing larger clinical trials and large multiple site trials
to fewer full-service CROs. For the year ended December 31, 1996, the Company's
top ten customers accounted for approximately 41% of the Company's combined net
revenue. One customer of the Company, a large international pharmaceutical
company with revenues in excess of $1.0 billion, accounted for approximately
12% of net revenues for the year ended December 31, 1996. The Company believes
that the loss of any of these customers, if not replaced or if services
provided to existing customers are not expanded, may have a material adverse
effect on the Company. There can be no assurance that the loss of any such
customers would be replaced or services to existing customers would be expanded
on terms acceptable to the Company.

                                     BACKLOG

         The Company reports backlog based on anticipated net revenues from
uncompleted projects which have been authorized by the client, through a written
contract or otherwise. Once work under a letter of intent or contract commences,
net service revenue is recognized over the life of the contract using the
percentage-of-completion method of accounting. In certain cases, the Company
will commence work on a project prior to finalizing a letter of intent or
contract. Contracts included in backlog are subject to termination or delay at
any time by the client or regulatory authorities. Termination or delays can
result from a number of factors, many of which are beyond the Company's control.
Delayed contracts remain in the Company's backlog pending determination of
whether to continue, modify or cancel the contract.

         The Company believes that its backlog as of any date is not necessarily
a meaningful indicator of future results and no assurance can be given that the
Company will be able to realize net service revenue included in backlog. As of
December 31, 1996, the Company's backlog was approximately $25.7 million
compared to approximately $19.4 million at December 31, 1995. One contract of
the Company accounted for approximately $9.1 million of the backlog at December
31, 1996. The Company anticipates that approximately $5.4 of the December 31,
1996 backlog will be realized after December 31, 1997. The $25.7 million of
backlog as of December 31, 1996 includes $2.0 million of a $20.0 million Phase
II and Phase III trial, for which the Company has a signed letter of intent.
This contract is with the client which accounted for approximately 12% of net
revenues in 1996. The $2.0 million included in backlog represents the
anticipated revenue to be earned for the initial phase of this contract.

                                   COMPETITION

         The Company competes primarily against pharmaceutical companies' own
in-house research departments, CROs and universities and teaching hospitals. The
CRO industry includes several hundred small, limited-service providers, several
medium-sized CROs, and a few full-service global drug development companies. The
Company believes that it is one of the few CROs that can provide comprehensive
international drug development services in competition with the largest
full-service global drug development companies. The CRO industry is
consolidating and, in recent years, several large, full-service competitors have
emerged. This trend of industry consolidation may result in greater competition
among the larger CROs for clients and possible candidates for further
consolidation for these larger CROs. Such large, full-service competitors may
have substantially greater capital, technical and other resources, may be better
known and may have more experienced personnel than the Company. The Company's
major competitors include: Covance, Inc.; Parexel International Corporation;
Quintiles Transnational Corporation; ClinTrials Research Inc.; Pharmaceutical
Products Development Corporation; Huntington International Holdings plc; and
IBAH, Inc.

        CROs generally compete on the basis of previous experience, medical and
scientific expertise in specific therapeutic areas, specialty preclinical
capabilities, the quality of contract research, the ability to organize and
manage large-scale trials on a global basis, the ability to manage large and
complex medical databases, the ability to provide statistical and regulatory
services, the ability to recruit investigators, the ability to integrate
information technology with systems to improve the efficiency of contract
research, an international presence with strategically located facilities,
financial viability, and in certain markets price is a significant factor.

         The Company possesses an exclusive license to a U.S. patent awarded to
Ohio University, covering DNA Microinjection, which is utilized in providing its
specialty transgenic based services.

                              GOVERNMENT REGULATION

         The Company's operations are subject to numerous regulatory
requirements designed to assure the quality and integrity of its drug
development services. In recent years, these regulations have become more
numerous and stringent, reflecting an increased public concern about the dangers
of potentially toxic drugs, chemicals and other substances. To the extent that
the following information describes statutory or regulatory provisions, it is
qualified in its entirety by reference to the particular statutory and
regulatory provisions currently in effect. Any change in applicable law or
regulation may have a material effect on the business and prospects of the
Company.

         The industry standard for conducting biological testing is embodied in
regulations called "Good Laboratory Practices." GLP has been adopted by the
Environmental Protection Agency ("EPA") and the FDA in the United States and the
Minister des Affaires Sociales et de la Solidarite Nationale in France. GLP
stipulates requirements for facilities, equipment and professional staff. The
regulations mandate standardized procedures for controlling studies, for

                                

                                       14


<PAGE>   15



recording and reporting data and for retaining appropriate records. The EPA, FDA
and any other governmental agency with the authority to control marketing
approval for new products can reject test results if they do not comply with
GLP. The Company monitors ongoing compliance with GLP standards. Additionally,
Organization of Economic Cooperation and Development ("OECD") member countries
(including France) must adopt GLP principles laid down by the OECD as indicated
in Directive 87/18/EEC.

         In addition, the Company is subject to scrutiny by many regulators
regarding its laboratories and materials. On the federal level in the United
States, the Company is regulated by the Department of Transportation ("DOT"),
Occupational Safety and Health Administration ("OSHA"), Nuclear Regulatory
Commission ("NRC") and the Drug Enforcement Administration ("DEA"). At the state
level, the Company is monitored by the Commonwealth of Pennsylvania Department
of Labor and Industry and the Pennsylvania Department of Environmental
Resources. In addition, certain of the Company's European operations are subject
to certain regulations in France similar to the aforementioned federal and state
regulations.

         In addition to the regulatory framework and GLP standards for
preclinical drug development services, the Company is and may be subject to
regulation under federal, state and foreign law, including requirements
regarding occupational safety, laboratory practices, the care and use of animals
in experimentation and testing, the use, handling and disposition of radioactive
materials, environmental protection and hazardous substance control, and may be
subject to other present and future local, state, federal and foreign
regulation, including future regulation of the preclinical drug development
industry, the biotechnology field and the biological testing industry.

         The clinical services provided by the Company are ultimately subject to
FDA regulation in the United States and comparable agencies in other countries,
although the level of applicable regulation in other countries is generally less
comprehensive than regulation present in the United States. The industry
standard for conducting clinical research and development studies is embodied in
regulations and guidelines called "Good Clinical Practices." Although the FDA
has not formally adopted a single GCP guideline, certain provisions of GCP have
been included in FDA regulations. In Europe, all work is carried out in
accordance with the EU Note For Guidance, "Good Clinical Practice for Trials on
Medicinal Products in the European Community." As a matter of practice, the FDA
and many other regulatory authorities require that test results submitted to
such authorities be based on studies conducted in accordance with GCP. These
regulations include: (i) complying with FDA regulations governing the selection
of qualified investigators; (ii) obtaining specific written commitments from the
investigators; (iii) verifying that patient informed consent is obtained; (iv)
monitoring the validity and accuracy of data; (v) verifying drug or device
accountability; and (vi) instructing investigators to maintain records and
reports. The Company must also maintain reports for each study for specified
periods for inspection by the study sponsor and the FDA and other applicable
regulatory authorities during audits. Non-compliance with GCP can result in the
disqualification of data collected during the clinical trial.

         The Company's standard operating procedures are written in accordance
with regulations and guidelines appropriate to the region where they will be
used. FDA regulations and

                                

                                       15


<PAGE>   16



guidelines serve as a basis for the North American standard operating
procedures. The Company has developed operating procedures in accordance with
local requirements and in harmony with the North American and European
operations. The Company has implemented common standard operating procedures
across geographic regions to assure consistency whenever it is feasible and
appropriate to do so. Complete external auditing services are provided by the
Company's U.S. and European operations.

                        POTENTIAL LIABILITY AND INSURANCE

         The Company attempts to manage its potential liability by obtaining
indemnity provisions in its contracts with clients and with investigators hired
by the Company on behalf of its clients. These indemnities generally do not,
however, protect the Company against certain of its own actions such as those
involving negligence. Moreover, these indemnities are contractual arrangements
that are subject to negotiation with individual clients, and the terms and scope
of such indemnities can vary from client to client and from study to study.
Finally, the financial performance of these indemnities is not secured, so that
the Company bears the risk that an indemnifying party may not have the financial
ability to fulfill its indemnification obligations. In addition to such
indemnification provisions, the Company maintains limited coverage for
professional service liability insurance. The Company could be materially and
adversely affected if it were required to pay damages or incur defense costs in
connection with a claim that is outside the scope of an indemnity or in excess
of its insurance coverage or where the indemnity, although applicable, is not
performed in accordance with its terms.

         The Company's believes that the risk of liability to patients in
clinical trials is mitigated by various regulatory requirements, including the
role of institutional review boards ("IRBs") and the need to obtain each
patient's informed consent. The FDA requires each human clinical trial to be
reviewed and approved by the IRB at each study site. An IRB is an independent
committee that includes both medical and nonmedical personnel and is obligated
to protect the interests of patients enrolled in the trial. After the trial
begins, the IRB monitors the protocol and the measures designed to protect
patients, such as the requirement to obtain informed consent.

                              INTELLECTUAL PROPERTY

         The Company has an exclusive commercial license to a U.S. patent
awarded to Ohio University in October 1989 covering DNA Microinjection, which is
the method of gene transfer widely employed for the successful development of
transgenic animals in several mammalian species. The Company has granted several
non-exclusive sublicenses for a variety of applications under this patent. The
Company, as it becomes aware of activities potentially infringing on its
commercial rights as the exclusive commercial licensee for the Ohio University
DNA Microinjection patent, takes appropriate action to curtail infringing
activities. There can be no assurance, however, that the Company's actions will
result in proof of infringement, curtailment of the potentially infringing
party's activities, or that the potentially infringing party will become
properly licensed and, thereby, financially obligated to the Company. Further,

                                

                                       16


<PAGE>   17



there can be no assurance that technology circumventing the DNA Microinjection
process may not be developed in the future; nor can there be any assurance that
if such technology is developed that the Company would be able to continue to
practice the processes contained in the DNA Microinjection patent or that the
Company would be able to obtain licenses for such new technology on reasonable
terms, if at all. Outside of the U.S., the DNA Microinjection process is
non-proprietary; however the commercialization of any products in the United
States using the DNA Microinjection process are protected by the patent. The
license has a term equal to the life of the last to expire of all patents
covered by the license, unless earlier terminated by either party for cause.

                                     NEXTRAN

         On August 29, 1994, the Company, through a wholly-owned subsidiary,
entered into a Joint Venture Agreement (the "Joint Venture Agreement") with
Baxter Transplant Holdings, Inc. ("Holdings"), a wholly owned subsidiary of
Baxter Healthcare Corporation ("Baxter"), which is a subsidiary of Baxter
International, Inc. ("Baxter International"). Under the Joint Venture Agreement,
the Company and Holdings formed Nextran, a Delaware general partnership
("Nextran"), in which the Company had a 30% partnership interest and Holdings
had a 70% partnership interest. In connection with the formation of Nextran, the
Company contributed $2.5 million in cash and certain rights under patent
licenses, research agreements, and other intangible assets related to its
xenograft (animal to human) organ transplantation and blood substitute programs,
including certain limited rights to practice under the DNA Microinjection patent
specifically within the xenograft and hemoglobin blood substitute fields of use.
In addition, the Company contributed laboratory and office space in Princeton,
New Jersey, swine research facilities near Athens, Ohio and certain related
equipment and other related assets with a net book value of $2.4 million to
Nextran. Baxter contributed to Nextran $20 million in cash and certain rights
under research and product marketing programs between Baxter and various third
parties related to certain of its transplantation programs.

         Pursuant to the terms of the Purchase Agreement, dated September 22,
1995, as amended, the Company consummated the sale of its 30% partnership
interest in Nextran to Transplant Acquisition Inc., a wholly-owned subsidiary of
Baxter, for a cash purchase price of $18 million. In connection with this
transaction, in the third quarter of 1995, the Company eliminated its investment
in Nextran and recorded an estimated non-recurring gain, net of expenses, income
taxes and related accruals, of approximately $17.3 million. Additionally, in the
event that Nextran develops and commercializes hemoglobin blood substitutes
using technologies licensed to Nextran by the Company, the Company will receive
royalty income of 3% of end product sales.

         The obligations of the subsidiary under the Joint Venture Agreement, an
asset transfer agreement and other related documents have been guaranteed by the
Company. Such guarantees expired on August 29, 1995, with the exception of
certain environmental representations and warranties which expire on August 29,
1997.

<PAGE>   18



                        RESEARCH AND DEVELOPMENT EXPENSES

         As the result of the sale of the Company's interest in Nextran as well
as the change in the strategic focus of the Company, the Company's research and
development expenses have decreased significantly since 1994. Research and
development expenses for 1996, 1995 and 1994 were approximately $500,000, $1.1
million and $3.9 million, respectively.

                                    EMPLOYEES

         As of December 31, 1996, the Company employed 396 individuals on a
full-time basis. None of the Company's U.S. employees are represented by trade
unions. All of the employees of its European preclinical operations, except
senior management, are represented by a legal trade union. These employees are
governed by an agreement, which is subject to renegotiation on an annual basis.
Although no employees of the European clinical operations are covered by a trade
union, many of its employees for its European clinical operations have written
contracts with the Company in accordance with local law. The Company believes
that it maintains good relations with its employees.

     into a Joint Venture Agreement with Baxter to form Nextran, a partnership
     in which the Company had a 30% partnership interest. On September 22, 1995,
     the Company consummated the sale of its 30% partnership interest in Nextran
     to Transplant Acquisition Inc. for a cash purchase price of $18 million. As
     a result of the sale of its partnership interest in Nextran, the Company
     recorded a non-recurring gain, net of expenses, income taxes and related
     accruals of approximately $17.3 million. See Note 7 of the Notes to
     Consolidated Financial Statements included in Part IV of this Annual Report

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

         The Company is an international contract research organization
providing a broad portfolio of integrated drug development services primarily to
the pharmaceutical and biotechnology industries. This portfolio of drug
development services includes preclinical and clinical capabilities that enable
the Company to manage a comprehensive drug development program or a client's
specific requirements. The Company utilizes its international expertise and
experience in preclinical and clinical services to provide a coordinated
approach for a client to transition its drug through various preclinical to
clinical stages of development thereby minimizing certain delays which typically
occur before a new drug is introduced to the market. In addition, the Company is
the only CRO that is currently able to use its proprietary transgenic and other
related technology to provide services for its clients that require transgenic
animal models for the evaluation of therapeutic lead compounds for further
development and for genomics research in order to determine the function of
human genes and identify gene targets implicated in disease. The Company
generates substantially all of its revenues from its drug development services
and currently provides services for more than 250 clients in 26 countries.

         On December 18, 1996, the Company issued 2,632,600 shares of Common
Stock in connection with the acquisition by the Company of all of the
outstanding capital stock of, or equity interests in, BioClin, Inc., a Delaware
corporation, BioClin Europe AG, a Swiss corporation, BioClin GmbH, a German
corporation, Kilmer N.V., a Netherlands Antilles corporation, and BioClin
Institute of Clinical Pharmacology GmbH, a German corporation. The Acquisition
is being recorded using the "pooling-of-interests" method of accounting. In
connection with the Acquisition, the Company incurred business combination costs
aggregating approximately $3.6 million.

         Chrysalis is also the exclusive commercial licensee of a U.S. patent
covering DNA Microinjection, the process widely used in the pharmaceutical and
biotechnology industries to develop transgenic animals. The Company utilizes
this license for its drug development services and grants sublicenses for the
use of this technology. These sublicenses entitle the Company to receive
revenues consisting of fees and, in certain cases, royalties.

         The Company's financial statements are denominated in U.S. dollars and,
accordingly, changes in the exchange rate between non-U.S. currencies and the
U.S. dollar will affect the translation of non-U.S. revenues and operating
results into U.S. dollars for purposes of reporting the Company's financial
results. Approximately 68% of the Company's revenues are from operations outside
the U.S. Approximately 48% of the Company's revenues for the year ended December
31, 1996 are from operations in France and are denominated in French Francs;
accordingly, fluctuations in the exchange rate between the French Franc and the
U.S. dollar may have a material effect on the Company's operating results. See
"-- Liquidity and Capital Requirements -- Exchange Rate Fluctuations."

         In addition, the Company may be subject to foreign currency transaction
risk when the Company's multi-country contracts are denominated in a currency
other than the currency in which

                                

                                       24


<PAGE>   25



the Company incurs the expenses related to such contracts. For such
multi-country drug contracts, the Company seeks to require its client to incur
the effect of fluctuations in the relative values of the contract currency and
the currency in which the expenses are incurred. To the extent the Company is
unable to require its clients to incur the effects of currency fluctuations,
these fluctuations could have a material effect on the results of operations of
the Company. The Company does not currently hedge against the risk of exchange
rate fluctuations.

         The Company's contracts are typically fixed price contracts that
require a portion of the contract amount to be paid at or near the time the
trial is initiated. The Company generally bills its clients upon the completion
of negotiated performance requirements and, to a lesser extent, on a date
certain basis. Certain of the Company's contracts are subject to cost
limitations which cannot be exceeded without client approval. Because, in many
cases, the Company bears the risk of cost overruns, unbudgeted costs in
connection with performing these contracts may have a detrimental effect on the
financial results of the Company. If it is determined that a loss will result
from the performance of a contract, the entire amount of the estimated loss is
charged against income in the period in which the determination is made.

         The Company's contracts generally may be terminated with or without
cause. In the event of termination, the Company is typically entitled to all
sums owed for work performed through the notice of termination and all costs
associated with termination of the study. In addition, most of the Company's
contracts provide for an early termination fee, the amount of which usually
declines as the work progresses. The loss of a large contract or the loss of
multiple contracts, however, could adversely affect the Company's future
revenues and profitability. In addition, termination or delay in the performance
of a contract occurs for various reasons, including, but not limited to,
unexpected or undesired results, inadequate patient enrollment or investigator
recruitment, production problems resulting in shortages of the drug being
tested, adverse patient reactions to the drug being tested, or the client's
decision to not proceed with a particular trial.

         Revenue for contracts extending over more than one accounting period is
recognized on a percentage of completion basis as work is performed. Revenue is
affected by the mix of trials conducted and the degree to which effort is
expended. The Company will incur travel costs and may subcontract with
third-party investigators in connection with multi-site clinical trials. These
costs are passed through to clients and, in accordance with industry practice,
are included in service revenue. The costs may vary significantly from contract
to contract; therefore, changes in service revenue may not be indicative of
trends in revenue growth. Accordingly, the Company considers net service
revenue, which consists of service revenue less these costs, as its primary
measure of revenue growth.

        The Company has had, and will continue to have, certain clients from
which at least 10% of the Company's overall revenue is generated over multiple
contracts. Such concentration of business is not uncommon within the CRO
industry. For the year ended December 31, 1996, the Company's top ten customers
accounted for approximately 41% of its combined net revenue. One customer
accounted for approximately 12% of the Company's net revenues in fiscal 1996.
The Company believes that the loss of any of these customers, if not replaced
or if services provided to existing customers are not expanded, may have a
material adverse effect on the Company. There can be no

                                

                                       25

assurance that the loss of any such customer would be replaced or services to
existing customers would be expanded on terms acceptable to the Company.

         The Company's quarterly operating results may fluctuate as a result of
various factors, such as delays experienced in implementing or completing
particular services and termination of services. Since a substantial portion of
the Company's operating costs are relatively fixed, while revenue is subject to
fluctuations, minor variations in the timing of services or the progress of
services may cause significant variations in quarterly operating results.
Results of one quarter are not necessarily indicative of results for the next
quarter.

         On August 29, 1994, the Company, through a wholly-owned subsidiary,
entered into the Joint Venture Agreement with Holdings, a wholly-owned
subsidiary of Baxter, which is a subsidiary of Baxter International. Under the
Joint Venture Agreement, the Company and Holdings formed Nextran, a Delaware
general partnership, in which the Company had a 30% partnership interest and
Holdings had a 70% partnership interest. Pursuant to the terms of the Purchase
Agreement, dated September 22, 1995, as amended, the Company consummated the
sale of its 30% partnership interest in Nextran to Transplant Acquisition Inc.,
a wholly-owned subsidiary Baxter, for a cash purchase price of $18 million. As a
result of these transactions, the Company is no longer required to use its
resources to fund the development of its organ transplantation or blood
substitute programs. Historically, these programs have accounted for a
substantial portion of the Company's research and development expenses, capital
expenditures, working capital and accumulated deficit. Prior to the sale of its
partnership interest in Nextran, the Company recorded its share of Nextran's
financial results of operations in its consolidated financial statements
according to the equity method of accounting.

         In 1995, the Company elected to discontinue providing services for
Phase I trials in the United States and to focus its resources on services for
Phase II through Phase IV trials and related data management services in the
United States. Net revenues related to these Phase I services in the United
States were approximately $3.5 million for the year ended December 31, 1995. The
Company has not generated any revenue for Phase I services in the United States
for fiscal 1996. The Company retains its capability to provide services for
Phase I trials for its clients through its operations in Dusseldorf, Germany.

         Fiscal year ended December 31, 1996 as compared to the fiscal years
ended December 31, 1995 and December 31, 1994.

         Revenues. Revenues were $41,487,000 for 1996 compared to $39,609,000
and $36,188,000 for 1995 and 1994, respectively. The increase of 4.7% in
revenues from 1995 to 1996 was due to an increase in business activity for the
preclinical drug development services in both the European and U.S. marketplace.
This increase in preclinical services was offset by a decrease in revenues from
clinical services. The Company believes the increase in preclinical business
activity is a result of the improvement in the pharmaceutical and biotechnology
industries outsourcing trends and expanded cash reserves within the
biotechnology sector. The decrease of approximately $2,400,000 in revenues for
the clinical business was due to the decision in 1995 to discontinue providing
services for Phase I trials in the U.S. which represented approximately
$3,500,000 in revenues for the clinical business in 1995. In addition, revenues
for the clinical business in 1996 were adversely affected by senior managements'
involvement in the negotiation and consummation of the Acquisition and,
consequently, having less opportunity than in 1995 to devote to business
development and marketing the clinical business.

         The increase of 9.5% in revenues from 1994 to 1995 was primarily a
result of an increase in the volume and scope of clinical research projects in
both the U.S. and European operations, offset by a decrease in revenues from the
preclinical business. The majority of the increase in revenues from the clinical
business was related to a contract with the clinical business' largest customer,
and a favorable effect amounting to approximately $943,000 for 1995 compared to
the same period in 1994 from the currency translation of the clinical business'
European revenues from German Marks and Swiss Francs to U.S. dollars. The
decrease in preclinical business revenues from 1994 to 1995 was primarily a
result of reduced research and development activity requiring preclinical
development services as a result of (i) government price control pressures on
pharmaceutical companies, (ii) increased consolidation in the pharmaceutical
industry causing delays in decisions that effect current preclinical drug
development efforts, and (iii) the effect of a difficult financial environment
(beginning in 1993 and ending in mid-1995) for biotechnology companies

requiring those companies to allocate cash resources to existing drug candidates
rather than developing new candidates which would require preclinical services.
This decrease was offset by a favorable effect amounting to approximately
$2,004,000 for the year ended December 31, 1995 compared to the same period in
1994 from the currency translation of French Francs to U.S. dollars.

         Operating Expenses. Direct costs were $27,313,000 or 66% of net
revenues for 1996, compared with $27,691,000 or 70% of net revenues for 1995.
For 1994 direct costs were $25,499,000 or 70% of net revenues. Although direct
costs remained relatively unchanged on a Company-wide basis for 1996 as compared
to 1995, direct costs associated with preclinical business increased as a result
of additional business activity, which resulted in an increase in variable costs
such as materials and supplies, offset by a decrease in direct costs for the
clinical business primarily due to the decision to discontinue providing
services for Phase I trials in the U.S.

         The increase in direct costs of $2,192,000 from 1994 to 1995 was
primarily due to an unfavorable effect from the currency translation from French
Francs to U.S. dollars. The direct costs for the Company's European preclinical
operations increased by approximately $291,000 in 1995 compared to the same
period in 1994 due to the unfavorable effect of the currency translation,
despite the fact that actual direct costs for the Company's European preclinical
operations decreased, on a U.S. dollar-to-U.S. dollar basis, by approximately
$1,244,000 since 1994 when applying the 1994 French Franc translation rate as a
constant to both the 1995 and 1994 expense levels. The increase in direct costs
was also a result of (i) Company-wide investment in personnel and infrastructure
to accommodate anticipated growth and to enhance the quality of services offered
and (ii) an expense recorded in association with a cost reduction program in
Europe. The increase in these direct costs was offset by a decrease in personnel
due to the decision to discontinue providing services for Phase I trials in the
U.S. The decrease in direct costs as a percent of revenues for 1996 is due to
the leveraging of a base cost structure of personnel and related infrastructure
which supported a higher level of business in 1996 than experienced during 1995
and 1994.

         Research and development expenses in 1996 decreased to $528,000 from
$1,063,000 in 1995, which decreased from $3,940,000 in 1994. The decrease in
research and development expenses for 1996 compared to 1995 was primarily the
result of the shift in the strategic focus of the Company's transgenic animal
services from the internal development of transgenic animal models to providing
commercial specialty drug development services. The decrease in these expenses
in 1995 compared to 1994 was primarily the result of the transfer of the
Company's biotechnology programs to Nextran in August 1994.

         General, administrative and marketing expenses increased to $10,942,000
in 1996 from $9,631,000 in 1995, which remained relatively unchanged from
$9,975,000 in 1994. The increase in these expenses from 1995 to 1996 was
primarily the result of an increase in costs for expansion of operations in
Eastern Europe, additional personnel for accounting, business development,
administration and information systems, increased personnel related costs and
increased sales, marketing and advertising expenses. Although these costs
remained unchanged from 1994 to 1995, included in 1994 were (i) $572,000 of
non-recurring general and administrative expenses, the majority of which were
associated with the formation of Nextran, and (ii) expenses for activities in
support of Nextran, while 1995 included (i) an increase in costs as a result of
the currency

translation from French Francs to U.S. dollars and (ii) increased expenses
associated with sales and marketing, administration and information systems in
preclinical and clinical operations.

         Depreciation and amortization decreased to $2,780,000 in 1996 from
$2,907,000 in 1995 and $3,594,000 in 1994. The decrease from 1994 to 1995 was a
result of the transfer of assets resulting from the Nextran transaction.

         Business Combination Costs. The Company incurred costs associated with
the Acquisition aggregating $3,649,000. These costs include expenses associated
with the acquisition of the clinical business, the name change from DNX
Corporation to Chrysalis and certain other related items. As of December 31,
1996, $1,380,000 of these costs remain to be paid and are classified as accrued
expenses in the Consolidated Financial Statements included in Part IV of this
Annual Report on Form 10-K.

         Other Income (Expense). Other income (expense) represented income of
$742,000 in 1996 compared to expense of $635,000 for 1995 and expense of
$525,000 for 1994. The primary reasons for the improvement in other income
(expense) in 1996 were interest income of $1,187,000 earned as the result of
higher cash balances primarily resulting from the sale of Nextran in the third
quarter of 1995 and foreign currency gain of $517,000 primarily as a result of
exchange rate fluctuations between the German Mark and Swiss Franc associated
with short-term borrowings of the Company's German operations denominated in
Swiss Francs. The Company repaid this debt denominated in Swiss Francs in 1997.
Such income was offset primarily by interest expense of $1,445,000 on
outstanding debt. The increase in other expense from 1995 to 1994 primarily
resulted from an increase of $240,000 in interest expense as a result of higher
outstanding debt balances and a foreign currency loss of $292,000 as a result of
exchange rate fluctuations between the German Mark and Swiss Franc associated
with short-term borrowings of the Company's German operations denominated in
Swiss Francs.

         Equity In Net Loss Of Nextran. As a result of its minority equity
ownership in Nextran, the Company recorded its share of Nextran's financial
results in its consolidated financial statements based on the equity method of
accounting. As a result of the sale of its partnership interest in Nextran, the
Company no longer records a share of Nextran's financial results of operations
in its consolidated financial statements subsequent to September 30, 1995. The
Company's share of Nextran's loss amounted to $2,700,000 for the period ended
September 30, 1995, as compared to $1,329,000 for the period from August 29,
1994 (the date of formation of Nextran) through December 31, 1994.

         Gain on Sale of Nextran. As a result of the sale of its partnership
interest in Nextran, in the third quarter of 1995 the Company eliminated its
investment in Nextran and recorded a non-recurring gain, net of expenses,
estimated income taxes of $200,000 and related accruals, of $17,266,000.

         Taxes. The Company's foreign subsidiaries are subject to foreign income
taxes under foreign tax laws on the profits generated in such countries which in
general may not be offset by losses from operations in other countries. As a
result, primarily for its French operations, the Company

                                

                                       29

recorded provisions for income taxes of $477,000 in fiscal 1996 compared to an
income tax benefit in 1995 of $177,000 and a provision for income taxes in 1994
of $390,000.

         The impact from United States federal income taxes is currently not
significant due to the Company's available net operating loss carryforwards. At
December 31, 1996, the Company has available net operating loss carryforwards of
approximately $25,396,000 for United States federal income tax purposes. Such
loss carryforwards expire through 2011. The Company also has research and
development tax credit carryforwards of approximately $3,000,000 for U.S.
federal income tax reporting purposes which are available to reduce U.S. federal
income taxes, if any, through 2010. The Company has alternative minimum tax
credit carryforwards of approximately $164,000 for U.S. federal income tax
purposes which are available to reduce U.S. federal income taxes, if any. These
tax credits have an unlimited carryforward period. The Company's acquisition of
the clinical drug development business, resulted in an ownership change under
the Internal Revenue Code of 1986, as amended (the "Code"). Accordingly, the
Company's ability to utilize its net operating loss carryforwards to offset
operating profits may be subject to certain limitations in the future under the
Code. These net operating loss carryforwards may not be utilized to offset
profit in other countries.

QUARTERLY RESULTS

         The Company's quarterly operating results are subject to variation, and
are expected to continue to be subject to variation, as a result of factors such
as delays in initiating or completing significant preclinical and clinical
trials, termination of preclinical and clinical trials, acquisitions and
exchange rate fluctuations. Delays and terminations of studies or trials are
often the result of actions taken by clients or regulatory authorities and are
not typically subject to the control of the Company. Since a large amount of the
Company's operating costs are relatively fixed while its revenues are subject to
fluctuation, minor variations in the commencement, progress or completion of
preclinical and clinical trials may cause significant variations in quarterly
operating results.

         The following table presents unaudited quarterly operating results for
each of the fiscal quarters of 1996. In the opinion of the Company, this
information has been prepared on the same basis as the audited consolidated
financial statements and reflects all adjustments (consisting only of normal
recurring adjustments) necessary for a fair presentation of results of
operations for those periods. This quarterly financial data should be read in
conjunction with the consolidated audited financial statements and notes thereto
included in Part IV of this Annual Report on Form 10-K. The operating results
for any quarter are not necessarily indicative of the results to be expected in
any future period.

LIQUIDITY AND CAPITAL REQUIREMENTS

         Cash Reserves. The Company finances its operations and activities by
relying on (i) its operating activities for its working capital requirements,
(ii) its cash reserves, and (iii) its available lines of credit. The Company
invests its excess cash in a diversified portfolio of high-grade money market
funds, United States Government-backed securities and commercial paper and
corporate obligations. As of December 31, 1996, the Company had cash reserves
(consisting of cash and cash equivalents, short-term investments, marketable
debt securities and restricted cash) of $18,480,000, including $4,550,000 in
escrow set aside for the payment of a portion of the outstanding short-term
debt. The Company generated $4,279,000 from operating activities during 1996,
and after the payment of $2,300,000 for business combination costs, cash from
operating activities was $1,979,000. The Company's cash reserves decreased by
$5,399,000 in 1996 primarily due to (i) the payment in December 1996 of
approximately $4,000,000 of outstanding short-term borrowings of the acquired
clinical business (see "-- Debt" below), (ii) the payment in December 1996 of
approximately $1,400,000 to retire the outstanding balances of the Company's
lines of credit in France and (iii) capital expenditures as described
immediately below.

                                

                                       31


<PAGE>   32



         Capital Expenditures. In 1996 the Company invested a total of
approximately $1,800,000 in property and equipment, as compared to approximately
$1,200,000 for fiscal 1995. This increase primarily reflects investments to
provide specialty preclinical services, to expand clinical services and to
enhance information systems capabilities. For 1997, the Company expects to
invest approximately $4,000,000 to $5,000,000 in capital expenditures related to
expansion of its clinical services, specialty and transgenic preclinical
services and information systems and data management capabilities.

         Debt. In connection with the Acquisition on December 18, 1996, the
Company acquired approximately $9.8 million of short-term borrowings outstanding
under line of credit arrangements with various banks. The majority of such
borrowings and credit arrangements were guaranteed by certain prior stockholders
of the clinical business. One of the conditions of the closing of the
Acquisition was the release of these guarantees. In order to satisfy this
condition, on December 18, 1996, the Company paid approximately $4.0 million to
reduce these short-term borrowings and transferred approximately $4.5 million
into escrow for purposes of securing the future payment of the remaining
personally guaranteed borrowings. The remaining outstanding balances under the
lines of credit arrangements, including the personally guaranteed borrowings,
were approximately $5.9 million at December 31, 1996. In January, the Company
paid approximately $4.2 million, using the funds from escrow, to retire the
remaining portion of personally guaranteed borrowings and terminated these lines
of credit. The approximately $300,000 remaining in escrow was then released.
In 1997, the Company established a new $3.0 million line of credit with a Swiss
bank. As of March 21, 1997, the outstanding balance under this line of credit
was approximately $625,000.

         Additionally, the Company has lines of credit and overdraft privileges
with French banks in the aggregate amount of 10.5 million French Francs ($2.0
million at the exchange rate in effect on December 31, 1996). At December 31,
1996 there were no short-term borrowings outstanding under these facilities as
compared to 6.9 million French Francs ($1.4 million at the exchange rate in
effect on December 31, 1995) at December 31, 1995.

         In December 1992, the Company acquired preclinical operations in
France. Included in the purchase price were promissory notes having an aggregate
principal amount of $7.0 million (the "Notes"). The remaining unpaid principal
balance as of December 31, 1996 of $5.0 million will be paid in December 1997.
The payment of the Notes is secured by a pledge of the capital stock of the
French operations, a pledge of certain assets, a guarantee by the Company and a
security interest in fees and royalties payable to the Company under sublicenses
of its proprietary DNA Microinjection technology. The Notes require prepayments
in specified amounts upon the Company selling any portion of its interest in the
preclinical business. The Notes contain various covenants, the most restrictive
of which prohibit the payment of dividends by the preclinical business to the
Company and the sale of any assets of the French operations that are not made in
the ordinary course of business.

         In connection with its U.S. preclinical facility, in 1994 the Company
secured (i) a $1.5 million 15-year mortgage with a bank, which required cash
collateral of $180,000, and (ii) a $1.2 million 15-year mortgage from a
Pennsylvania agency, which required cash collateral of $450,000. These two loans
are also secured by mortgages on the property acquired. As a result

                                

                                       32


<PAGE>   33



of the Company's preclinical business achieving certain financial covenants, the
cash collateral on the mortgage loan with the bank was released in 1995. The
cash collateral on the mortgage loan with the Pennsylvania agency is classified
as restricted cash as of December 31, 1996. Upon achievement of certain
financial covenants, this $450,000 of cash collateral will be released.
Additionally, the favorable interest rate on the mortgage with the Pennsylvania
agency is subject to change upon review by the agency of certain future
conditions.

         Capital Requirements. The Company believes that with its current
financial resources it has the ability to meet its working capital requirements
for the foreseeable future. The Company anticipates that its future capital
requirements may include investment for expansion of its operating
infrastructure to meet anticipated increased demand for drug development
services from the pharmaceutical and biotechnology industries. In addition, a
$5.0 million payment on the principal balance of the Notes will be due in
December 1997. The Company may also, from time to time, consider funding its
capital requirements by issuing stock or other securities in public or private
equity or debt financings. Additionally, the Company from time to time is
engaged in discussions regarding strategic acquisitions of organizations
providing various drug development services and may finance such an acquisition
with its existing cash resources or by additional public or private debt or
equity financings or through the issuance of stock. In the event that the
Company seeks to issue stock or other securities or pursue any such acquisition
requiring financing, there can be no assurance that the Company will be able to
issue such stock or other securities or that any financing will be available to
the Company or that such offering or financing will be available on acceptable
terms. Also, there can be no assurance that the Company will consummate such an
acquisition or obtain any such financing, or if consummated, that the Company
will be able to issue such stock or other securities or obtain any such
financing arrangements will satisfy a material portion of the Company's capital
needs. Although the Company continually considers and evaluates potential
acquisitions and related opportunities for growth, it does not have any
understandings, arrangements or agreements with respect to any such
acquisitions.

         As a former general partner of Nextran, the Company remains obligated
with respect to certain environmental representations and warranties which
expire on August 29, 1997. Such representations and warranties are also limited
by certain financial indemnification provisions.

         The Company's working capital and other capital requirements will
depend on numerous factors, including among others: success in increasing the
Company's revenues and managing its operations; exchange rate fluctuations
between the United States dollar and foreign currencies; capital expenditures
for clinical and preclinical information system objectives; the level of Company
resources devoted to management, marketing, information and data management
capabilities and business and financial administration; technological advances;
the status of competitors; the payment of remaining expenses for the acquisition
of the clinical drug development business; and costs of potential future
acquisitions.

EXCHANGE RATE FLUCTUATIONS

         Approximately 68%, 63% and 63% of the Company's net revenues for 1996,
1995 and 1994, respectively, were derived from the Company's operations outside
the United States. The Company's consolidated financial statements are
denominated in U.S. dollars and, accordingly,

                                

                                       33


<PAGE>   34



changes in exchange rates between the applicable foreign currency and the U.S.
dollar will affect the translation of such subsidiary's financial results into
U.S. dollars for purposes of reporting the Company's consolidated financial
results.

         The Company may be subject to foreign currency transaction risks when
the Company's multi-country contracts are denominated in a currency other than
the currency in which the Company incurs the expenses related to such contracts.
For such multi-country contracts, the Company seeks to require its client to
incur the effect of fluctuations in the relative values of the contract currency
and the currency in which the expenses are incurred. To the extent the Company
is unable to require its clients to incur the effects of currency fluctuations,
these fluctuations could have a material effect on the results of operations of
the Company.

         Translation adjustments are reported as a separate section of
stockholders' equity. The Company generally does not hedge its currency
translation and transaction exposure.

         Due to its preclinical operations in France, the percentage of the
Company's total revenues recorded in French Francs is significant. For the
fiscal years 1996, 1995 and 1994, the French operations accounted for
approximately 48%, 44% and 51% of the Company's revenues, respectively.
Accordingly, changes in the exchange rate between the French Franc and the U.S.
dollar will affect the translation of the French preclinical operation's
revenues and operating results into U.S. dollars for purposes of reporting the
Company's consolidated financial results, and also affect the U.S. dollar
amounts actually received by the Company from the French preclinical operations.
Based on the assumption that the French preclinical operations will continue to
represent a significant portion of the business of the Company, the depreciation
of the U.S. dollar against the French Franc would have a favorable impact on the
Company's revenues and an unfavorable impact on the Company's operating expenses
due to the effect of such currency translation on the French preclinical
operation's operating results; however, the appreciation of the U.S. dollar
against the French Franc would have an unfavorable impact on the Company's
revenues and a favorable impact on the Company's operating expenses.

         For purposes of the Company's consolidated financial results, the
results of operations of the French preclinical business denominated in French
Francs have been translated from French Francs into U.S. dollars using the
following exchange rates:

         In the first quarter of 1997, the U.S. dollar has strengthened against
the French Franc, the German Mark and the Swiss Franc. As of March 21, 1997, the
French Franc was 5.7145 per U.S. dollar. The strengthened U.S. dollar may have
an impact on the Company's results of operations.

ACCUMULATED DEFICIT

         Since its inception in 1988 until the formation and subsequent sale of
its partnership interest in Nextran in 1995, the Company expended substantial
funds for research and development and capital expenditures. A significant
portion of such expenditures were made to support the Company's organ
transplantation and blood substitute research and development programs, which
programs were transferred to the Nextran partnership. Historically, these
expenditures accounted for a substantial portion of the Company's accumulated
deficit.

INFLATION

         The Company believes that inflation has not had a material impact on
its results of operations.

Financial Condition and Results of Operations" and elsewhere throughout this
Annual Report on Form 10-K that are not historical facts are "forward-looking
statements" within the meaning of Section 27A of the Securities Act of 1933 and
Section 21E of the Securities Exchange of 1934. These forward-looking statements
are subject to certain risks and uncertainties described below, which could
cause actual results to differ materially from those reflected in the
forward-looking statements. These forward-looking statements reflect
management's analysis, judgment, belief or expectation only as of the date
hereof. The Company undertakes no obligation to publicly revise these
forward-looking statements to reflect events or circumstances that arise after
the date hereof.

         Factors that could cause actual results to differ materially from those
reflected in the forward looking statements include, without limitation: the
degree of the Company's success in obtaining new contracts; the scope and
duration of drug development trials; the loss or downsizing of or delay in
existing drug development trials; the Company's dependence on certain clients,
especially its largest clinical client, which in 1996 accounted for
approximately 12% of net revenues, and on the pharmaceutical and biotechnology
industries; the Company's dependence on key management personnel; competition
and consolidation in the drug development services industry; liability for
negligence or errors and omissions arising out of drug development trials;
foreign exchange rate fluctuations; and the costs associated with integrating
future acquired businesses. In addition, the Company's quarterly operating
results will continue to be subject to variation as a result of factors such as
those discussed above as well as the costs associated with integrating the
clinical and preclinical businesses.

                          INDEPENDENT AUDITORS' REPORT
                          ----------------------------

The Board of Directors and Stockholders
Chrysalis International Corporation:

We have audited the accompanying consolidated balance sheets of Chrysalis
International Corporation and subsidiaries as of December 31, 1996 and 1995, and
the related consolidated statements of operations, stockholders' equity, and
cash flows for each of the years in the three-year period ended December 31,
1996. These consolidated financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
consolidated financial statements based on our audits. We did not audit the
financial statements of Nextran (a 30 percent owned general partnership) for the
year ended December 31, 1994. The Company's equity in the loss of Nextran was
$1,329,000 for the year ended December 31, 1994. The financial statements of
Nextran were audited by other auditors in 1994 whose report has been furnished
to us, and our opinion, insofar as it relates to the amounts included for
Nextran in 1994, is based solely on the report of the other auditors.

We conducted our audits 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 audits and the report of the other auditors in 1994 provide
a reasonable basis for our opinion.

In our opinion, based on our audits and the report of the other auditors in
1994, the consolidated financial statements referred to above present fairly, in
all material respects, the financial position of Chrysalis International
Corporation and subsidiaries as of December 31, 1996 and 1995, and the results
of their operations and their cash flows for each of the years in the three-year
period ended December 31, 1996, in conformity with generally accepted accounting
principles.

              CHRYSALIS INTERNATIONAL CORPORATION AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        DECEMBER 31, 1996, 1995 AND 1994


(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Organization:

         Chrysalis International Corporation, a Delaware Corporation
incorporated in 1988, (the " Company" or "Chrysalis"), formerly DNX Corporation
("DNX"), is an international contract research organization ("CRO") providing a
broad portfolio of integrated drug development services primarily to the
pharmaceutical and biotechnology industries. This portfolio of drug development
services includes preclinical and clinical capabilities that enable the Company
to manage a comprehensive drug development program or a client's specific
requirements. The Company generates substantially all of its revenues from its
drug development services business and services more than 250 clients in 26
countries.

         On December 18, 1996, the Company issued 2,632,600 shares of Common
Stock in connection with the acquisition (the "Acquisition") by the Company of
all of the outstanding capital stock of, or equity interests in, BioClin, Inc.,
a Delaware corporation, BioClin Europe AG, a Swiss corporation, BioClin GmbH, a
German corporation, Kilmer N.V., a Netherlands Antilles corporation, and BioClin
Institute of Clinical Pharmacology GmbH, a German corporation (collectively, the
"BioClin Group"). This transaction is being recorded using the
"pooling-of-interests" method of accounting (note 5).

         Chrysalis is also the exclusive commercial licensee of a U.S. patent
covering Pronuclear DNA Microinjection technology, the process widely used in
the pharmaceutical and biotechnology industries to develop transgenic animals.
The Company utilizes this license for its drug development services and grants
sublicenses for the use of this technology. These sublicenses entitle the
Company to receive revenues consisting of fees and, in certain cases, royalties.

Principles of consolidation:

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

Revenue recognition:

         Revenues from services are generally recognized in accordance with the
terms of the contract and in the periods in which the related services have been
rendered and the related costs incurred. Revenue related to contract
modifications is recognized after performance and when realization is assured
and the amounts are reasonably determinable. Adjustments to contract cost
estimates are made in the period in which the facts which require the revisions
become known. When the revised estimate indicates a loss, such loss is provided
for in its entirety. Revenues earned but not billed as of a given date are
reflected in the accompanying consolidated balance sheets as trade accounts
receivable (note 3). Funds received that relate to future performance under
service contracts are deferred and recognized as revenue when earned.

         Revenue from other contracts, primarily cost plus fixed-fee government
contracts, is recognized in the period in which the related services have been
rendered and costs incurred.

         Revenue from license fees is recognized upon issuance or renewal of
technology licenses. Additionally, sublicenses of the Company's proprietary DNA
Microinjection technology entitle the Company to receive additional revenues
consisting of royalties and milestone payments, which amounts are recognized as
revenue when received. To date, no material revenues have been received from
royalties and milestone payments.

Reimbursed costs:

         Substantially all amounts recorded as reimbursed costs in the
accompanying statements of operations relate to independent investigator and
travel costs. These costs are reimbursed by sponsors of the respective studies
in accordance with the respective contract terms. Payments received from
sponsors for investigator and travel costs in excess of costs incurred are
classified as deferred revenue and costs incurred in excess of amounts paid by
sponsors are classified as trade accounts receivable--unbilled.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)



(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED

Cash and cash equivalents and short-term investments:

         The Company considers all highly liquid investments with an original
maturity of three months or less to be cash equivalents. Cash equivalents
consist primarily of money market funds, corporate obligations and U.S.
Government obligations and are carried at cost, which approximates market value.
Short-term investments consist primarily of U.S. Government and corporate
obligations which mature in 1996. The Company has both the intent and ability to
hold its investments until maturity, and accordingly, all investments are
carried at amortized cost.

         The Company adopted Statement of Financial Accounting Standards No. 115
Accounting for Certain Investments in Debt and Equity Securities (FAS 115) as of
January 1, 1994. Under this standard, the Company is required to classify its
marketable debt securities into one or more of the following categories:
held-to-maturity, trading or available-for-sale. All of the Company's marketable
debt securities are foreign corporate debt securities and are classified as
available-for-sale. In accordance with FAS 115, securities available-for-sale
are recorded at fair market value and any unrealized gains or losses are
recorded as part of stockholders' equity.

Concentration of credit risks:

         The Company invests its excess cash in deposits with major financial
institutions, money market funds and notes issued by companies with strong
credit ratings. The Company has established guidelines relating to
diversification and maturities that maintain safety and liquidity. To date, the
Company has not experienced any losses on its cash equivalents and short-term
investments.

         The Company extends unsecured trade credit in connection with its
commercial services to a diversified customer base comprised of both foreign and
domestic entities, most of which are concentrated in the pharmaceutical and
biotechnology industries.

Property and equipment:

         Major additions and replacements of assets are capitalized at cost.
Maintenance, repairs and minor replacements are expensed as incurred. Property
and equipment are depreciated using the straight-line method over the following
periods: buildings and improvements--twenty to forty years; laboratory
equipment, vehicles, office and computer equipment, furniture and
software--three to ten years. Leasehold improvements are amortized using the
straight-line method over the estimated useful life of the asset or the lease
term, whichever is shorter. Upon retirement or sale, the cost of the assets
disposed of and the related accumulated depreciation are removed from the
accounts and any resulting gain or loss is credited or charged to operations.
Equipment leased under capital leases is capitalized with corresponding payment
obligations recorded in current and long-term debt.

Intangible assets:

         Costs in excess of net assets acquired are capitalized and are being
amortized on a straight-line basis over twenty years.

         Costs incurred in filing for patents are capitalized. Capitalized costs
related to unsuccessful patent applications are expensed when it becomes
determinable that such applications will be rejected. Capitalized costs related
to successful patent applications are amortized on a straight-line basis over a
period not to exceed seventeen years or the remaining life of the patent,
whichever is shorter.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED

Income taxes:

         The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109 "Accounting for Income Taxes" (FAS 109).
Under the asset and liability method of FAS 109, deferred tax assets and
liabilities are recognized for the estimated future tax consequences
attributable to differences between the financial statement carrying amounts of
existing assets and liabilities and their respective tax bases. Deferred tax
assets and liabilities are measured using enacted tax rates in effect for the
year in which those temporary differences are expected to be recovered or
settled. Valuation allowances are established to reduce deferred tax assets if
it is determined to be "more likely than not" that all or some portion of the
potential deferred tax assets will not be realized. Under FAS 109, the effect on
deferred tax assets and liabilities of a change in tax rates is recognized in
income in the period that includes the enactment date of the tax rate change.

Earnings (loss) per share:

         Earnings (loss) per common and common equivalent share is computed
based upon the weighted average number of common shares outstanding during the
periods plus, when their effect is dilutive, common stock equivalents consisting
of certain shares subject to stock options and warrants. All common share and
per share amounts have been adjusted to give effect to the pooling-of-interests
transaction with the BioClin Group. Primary and fully diluted earnings (loss)
per share are the same for all periods presented.

Foreign currency translation:

         The financial statements of the Company's European subsidiaries are
translated into U.S. dollars in accordance with Statement of Financial
Accounting Standards No. 52, "Foreign Currency Translation." Substantially all
assets and liabilities are translated at year-end exchange rates and income and
expense items are translated at an average exchange rate. Exchange adjustments
resulting from foreign currency transactions are generally recognized in
operations, whereas adjustments resulting from the translation of financial
statements are reflected as a separate component of stockholders' equity.

Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed Of:

         The Company adopted the provisions of SFAS No. 121, Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of, on
January 1, 1996. This Statement requires that long-lived assets and certain
identifiable intangibles be reviewed for impairment whenever events or changes
in circumstances indicate that the carrying amount of an asset may not be
recoverable. Recoverability of assets to be held and used is measured by a
comparison of the carrying amount of an asset to future net cash flows expected
to be generated by the asset. If such assets are considered to be impaired, the
impairment to be recognized is measured by the amount by which the carrying
amount of the assets exceed the fair value of the assets. Assets to be disposed
of are reported at the lower of the carrying amount or fair value less costs to
sell. Adoption of this Statement did not have a material impact on the Company's
financial position, results of operations, or liquidity.

Stock Option Plans:

         Prior to January 1, 1996, the Company accounted for its stock option
plans in accordance with the provisions of Accounting Principles Board ("APB")
Opinion No. 25, Accounting for Stock Issued to Employees, and related
interpretations. As such, compensation expense would be recorded on the date of
grant only if the current market price of the underlying stock exceeded the
exercise price. On January 1, 1996, the Company adopted SFAS No. 123, Accounting
for Stock-Based Compensation, which permits entities to recognize as expense
over the vesting period the fair value of all stock-based awards on the date of
grant. Alternatively, SFAS No. 123 also allows entities to continue to apply the
provisions of APB Opinion No. 25 and provide pro forma net income and pro forma
earnings per share disclosures for employee stock option grants made in 1995 and
future years as if the fair-value-based method defined in SFAS No. 123 had been
applied. The Company has elected to continue to apply the provisions of APB
Opinion No. 25 and provide the pro forma disclosure provisions of SFAS No. 123.

(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED

Use of estimates:

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

 Reclassification:

         Certain amounts contained in the 1995 and 1994 consolidated financial
statements have been reclassified to conform to the 1996 presentation.


(2)  MARKETABLE DEBT SECURITIES

         Marketable debt securities outstanding at December 31, 1996 and 1995
are available for sale and are recorded in the accompanying combined balance
sheets at fair value.

              CHRYSALIS INTERNATIONAL CORPORATION AND SUBSIDIARIES
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


(10)  LONG-TERM DEBT, CONTINUED

         The Promissory Notes in the original principal amount of $7,000,000
issued by the preclinical business in the French operation acquisition are
guaranteed by the Company and are secured by a pledge of the French operation's
common stock, the unsecured assets of the preclinical business, and an interest
in any royalties derived by the Company under certain sublicense agreements. The
promissory notes require prepayments in specified amounts upon the Company
selling any of its shares of common stock of the preclinical business. Also, if
the Company is reimbursed by the sellers of the French operation for any losses
suffered with respect to contractual representations and warranties made by the
sellers, such reimbursement can be set-off against the principal balance on the
promissory notes. The promissory notes contain various covenants, the most
restrictive of which prohibit the payment of dividends by the preclinical
business to the Company and the sale of any of the French operation's assets
that are not made in the ordinary course of business.

         In connection with its U.S. facility, the preclinical business secured
(i) a $1.5 million 15-year mortgage with a bank, which originally required cash
collateral of $180,000, and (ii) a $1.2 million 15-year mortgage from a
Pennsylvania agency, which required cash collateral of $450,000. These two loans
are also secured by mortgages on the property acquired. As a result of achieving
certain financial covenants, the cash collateral on the mortgage loan with the
bank was released in 1995. The cash collateral on the mortgage with the
Pennsylvania agency is classified as restricted cash as of December 31, 1996. If
the Company achieves certain financial milestones, this $450,000 of cash
collateral will be released. Additionally, the favorable interest rate on the
mortgage with the Pennsylvania agency is subject to change upon review by the
agency of certain future conditions.

         In May 1994, the preclinical business obtained a $500,000 equipment
loan from a Pennsylvania agency secured by certain of the equipment required in
connection with the expansion of the preclinical business' United States
operations. The loan is payable in equal monthly installments, with interest at
3.5%, through June 2001. The funding period for this loan ended on December 31,
1995. In April 1996, $288,000, representing the unused proceeds from this
equipment loan, was returned to the Pennsylvania agency.


(11)  STOCKHOLDERS' EQUITY

 Warrants:

         In 1994, in conjunction with a financial consulting and advisory
arrangement, the Company issued a warrant to purchase 110,000 shares of Common
Stock exercisable at $4.25 per share to the advisor. The warrant is currently
exercisable and expires on December 31, 1997.


(12)  STOCK OPTION PLANS

         The Company maintains three stock incentive plans, the 1988 Stock Plan,
the 1991 Stock Option Plan and the 1996 Stock Option Plan, (the Plans), which
provide for the granting of options to officers, directors, employees and
consultants at an option price which approximates the fair market value of such
common shares at the date of grant as determined by the Board of Directors. The
Plans provide for an aggregate of 2,460,250 options to be granted. The options
are exercisable for a period of ten years after the date of grant and generally
vest over a four-year period. The weighted average exercise price of the options
granted under these plans was $3.75 per share and $5.39 per share at December
31, 1996 and 1995, respectively.

         The weighted average fair values of stock options granted during 1996
and 1995 were $1.97 and $2.77 per share respectively. Such fair values are
estimated on the date of grant using the Black-Scholes option-pricing model with
the following weighted-average assumptions: dividend yield of 0%; expected
volatility of 35%; risk-free interest rates of 7%; and expected lives of 7
years.

(12)  STOCK OPTION PLANS, CONTINUED

         The Company applies APB Opinion No. 25 in accounting for its Plans. Had
the Company determined compensation cost based on the fair value at the grant
date for its stock options under SFAS No. 123, the Company's net income (loss)
would have been reduced to the pro forma amounts indicated below:

              Pro forma                        (3,711)      12,282
</TABLE>

         The pro forma net income (loss) reflects only the options granted in
1996 and 1995. Therefore, the full impact of calculating compensation cost for
stock options under SFAS No. 123 is not reflected in the pro forma net income
(loss) amounts presented above because compensation cost is reflected over the
option's vesting period of four years and compensation cost for options granted
prior to January 1, 1995 is not considered.

1996, 1995 and 1994 are as follows:

         For certain options granted prior to the Company's initial public
offering in 1991, the Company recognized as deferred compensation the excess of
the estimated fair value for accounting purposes of the common stock issuable
upon exercise of such options over the aggregate exercise price of such options.
Such deferred compensation aggregated $1,200,000 and is amortized ratably over
the four-year vesting period commencing October 1, 1991. Compensation expense
recognized amounted to $104,000 and $331,000 during 1995 and 1994, respectively.

         Most retirement benefits in France are paid out under the auspices of a
government-sponsored defined contribution retirement plan. Under the terms of
labor agreements, however, employees are entitled to an additional lump sum
payment at retirement provided they are still employed by the preclinical French
operation at their normal retirement date.

Profit-sharing of the operations in France:

         Profit-sharing is a requirement under French law. The payments are made
to employees after a period of 5 years unless certain conditions are met and
payment can be made earlier. During 1996, 1995 and 1994, profit sharing costs
aggregated $181,000, $0 and $190,000, respectively.

Savings Plan:

         The Company has an employee savings plan ("Savings Plan"), that
qualifies as a deferred salary arrangement under Section 401(k) of the Internal
Revenue Code. Under the Savings Plan, participating U.S. employees may defer a
portion of their pretax earnings, up to the Internal Revenue Service annual
contribution limit. Effective May 1, 1993, the company amended the Savings Plan
to provide for a Company match of 50% of each employee's contributions with
newly issued common stock of the Company. For the years ended December 31, 1996,
1995 and 1994, the Company issued 18,065, 14,563 and 30,977 shares of common
stock, respectively, to participants in the savings plan. Charges to operations
for the years ended December 31, 1996, 1995 and 1994 aggregated $95,000, $56,000
and $134,000, respectively, under this plan.

(17)  LEGAL PROCEEDINGS

         In the ordinary course of business, the Company is involved in certain
legal actions. In the opinion of management, based upon the advice of counsel,
the resolution of these legal matters will not have a material effect upon the
Company or its financial condition.

         In 1995, the Company terminated its relationship with the Virginia
Commonwealth University (VCU), which performed Phase I and analytical services
on behalf of the Company in the United States. The Company expects to sign a
settlement agreement with VCU in fiscal year 1997. The settlement may be
significantly less than the recorded liability of approximately $794,000, which
could result in a substantial book gain to the Company. In accordance with
Statement of Financial Accounting Standards No. 5, "Accounting for
Contingencies," the Company will recognize this gain when, and if, realized.


(18)  BUSINESS SEGMENT AND CUSTOMER INFORMATION

Business segment information:

         The Company operates in two geographic areas. Information on the
Company's geographic operations is set forth in the table below. North American

(20)  DISCLOSURE ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

Cash and cash equivalents, short-term investments, trade accounts receivable,
accrued interest receivable, restricted cash, accounts payable, and accrued
expenses:

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

Long-term debt:

         The carrying amount of long-term debt with variable interest rates
approximates fair value due to its variable nature. The fair value of long-term
debt with fixed interest rates is estimated on the current rates offered to the
Company for debt of the same remaining maturities. The carrying amount of
long-term debt with fixed interest rates aggregated $1,103,000 and $1,378,000
while the fair value approximated $642,000 and $783,000 as of December 31, 1996
and 1995, respectively.

Dear John:

This letter sets forth our agreement with respect to your employment with DNX
Corporation and any subsidiary or affiliate thereof (collectively referred to
herein as the "Company") and special separation benefits relating to the
termination thereof, as follows:

          1. POSITION AND DUTIES: Prior to termination of your employment and
subject to Section 4(b) hereof, you will devote your full time and attention to
the operations and affairs of the Company with such duties and responsibilities
as the Chief Executive Officer of DNX Corporation may reasonably determine;
provided, however, that such duties and responsibilities shall be consistent
with being Chief Financial Officer, and further provided, that if the duties and
responsibilities are changed so they are not consistent with being the Chief
Financial Officer, such duties and responsibilities as you and the Chief
Executive Officer may mutually agree within 30 days and if no mutual agreement
is reached you may treat such change of duties and responsibilities as a
termination of your employment pursuant to Section 4 below.

          2. COMPENSATION: Prior to the termination of your employment, you will
be paid biweekly at the annual rate of $135,000, or as authorized by the
Compensation Committee of the Board of Directors of DNX Corporation. Such
compensation shall be paid in accordance with the Company's normal procedures
for compensating its employees and shall be subject to withholding for
applicable taxes or government charges.

          3. BENEFITS: Prior to the termination of your employment, you will
remain eligible to participate in such vacation, medical, dental, 401(k)
savings, life, and disability benefit programs as may be established by the
Company, and, you will remain eligible to participate in the DNX Corporation
1988 and 1991 Stock Option Plans, as authorized by the Compensation Committee of
the Board of Directors of DNX Corporation.

          4. SEVERANCE OBLIGATIONS: (a) Following the termination of your

          months following your termination date. Any payments made would be
          reduced by applicable taxes and other required withholdings; 

          (2) continuation of medical and dental insurance coverage until the
          earlier of (i) the date you are eligible for similar coverage at a

you are terminated within 12 months after such Change of Control (unless your
employment is terminated for "cause" as defined below and subject to Section 5
below), or (ii) if (A) your duties and responsibilities after the consummation

unless you and the Board of Directors mutually agree on or prior to 30 days
before the consummation of the transaction effecting the Change of Control that
the provisions of this Section 4(b) shall not apply if your duties and
responsibilities are or will be changed as a result of the transaction effecting
the Change of Control so they are not consistent with being the Chief Financial
Officer or an equivalent position at a public company which is not a subsidiary
of any other corporation, partnership or other entity, the Company will provide
to you:

          (1) biweekly severance payments at the rate of your base salary at the
              time of termination for a period of 12 months regardless of
              employment status;

          (2) continuation of medical and dental insurance coverage until the
              earlier of (i) the date you are eligible for similar coverage at a

fraudulent or dishonest conduct or a material breach of any of the Company's
policies, (b) conviction of a felony or knowing violation of any federal, state,

proper cause, to substantially perform your duties after a demand for
substantial performance has been delivered to you in writing by your
supervisor(s). Upon termination for "cause", the Company shall have no further
liability or obligation to you, except for salary earned but not paid and other
obligations mandated by law.

          5. RELEASE: In consideration for the special separation benefits set
forth in Section 4 above, you shall agree to the conditions outlined on the

          In return for and in consideration of the special separation benefits
set forth in the attached letter dated May 28, 1996, I, John G. Cooper, on

without limitation any and all management and supervisory personnel thereof
(collectively referred to herein as the "Company"), from any and all actions and
causes of action, claims and demands, suits, damages, costs, attorney's fees,
expenses, debts, dues, accounts, bonds, covenants, contracts, agreements and
compensation whatsoever, whether in law or equity, whether they are now known or

          In connection with this Release, I further acknowledge, admit and
affirm the following:

waived and released by me under this Release are any and all claims arising
under the Age Discrimination in Employment Act of 1967.

              3. I understand that this Release does not waive rights or claims
arising under the Age Discrimination in Employment Act of 1967 that may arise
after the date this Release is signed.

              4. I am herein advised in writing that with regard to my waiver of
rights under this Release, including under the Age Discrimination in Employment
Act of 1967, I have the right to consult with and be advised by a lawyer of my
own choice at my own expense prior to signing this Release.

              5. I understand that I have 21 days to consider this Release, and
to consult with a lawyer regarding its terms and the rights and claims I am
waiving by signing it, before I sign this Release. This 21-day consideration

Company's records, documents or other property in my possession. This
representation is material to the Company's offer to me of the terms set forth

commence effective as of the closing of the acquisition of BioClin (Europe) AG
by the Company (the "Effective Date"). During the term of this agreement (unless
earlier terminated as provided below), you will devote substantially your full
time and attention to the operations and affairs of the Company with such duties

Worldwide Clinical Services, such duties and responsibilities as you and the

agreement is reached, you may treat such change of duties and responsibilities
as a termination of your employment by the Company pursuant to paragraph 4
below. You will perform your duties and responsibilities at the Company's

Committee for compensating the Company's domestic employees and shall be subject

benefits set forth in section 4 above, you agree that (a) if your employment is
