ITEM 1. BUSINESS

General

         Premier Research Worldwide, Ltd. (the "Company") is a clinical research
organization ("CRO") providing a broad range of integrated product development
services to its clients in the pharmaceutical, biotechnology and medical device
industries. The Company's services include centralized diagnostic testing,
clinical trial management, clinical data management, biostatistical analysis,
health care economics and outcomes research and regulatory affairs services. In
addition, the Company develops, markets and supports clinical trial software
products.

         All of the Company's services are designed to help clients reduce their
product development time in a cost-effective manner. In 1977, the Company's
predecessor, Cardio Data Systems, began providing diagnostic testing services
used to evaluate the safety and efficacy of new drugs. Today, the Company
provides these services, which include electrocardiograms ("ECGs"), Holter
monitoring, pulmonary function testing, blood and urine sampling, and other
tests, on a centralized basis. To take advantage of the potential synergies and
cross-selling opportunities with its centralized diagnostic testing services,
the Company added clinical trial management capabilities in September 1995 by
forming with PREMIER, Inc. (a large voluntary healthcare alliance),
a limited liability company, which was owned 65% by the Company and 35% by
PREMIER, Inc. Upon the closing of the Company's initial public offering of its
Common Stock in February 1997, PREMIER, Inc.'s minority interest in this limited
liability company was converted into 330,150 shares of Common Stock of the
Company.

         During 1997, the Company acquired the assets and business of DLB
Systems, Ltd. ("DLB"), a provider of clinical trial and data management software
and services to the pharmaceutical, biotechnology and device industry. The
acquisition of DLB provides the opportunity to extend the Company's clinical
data management expertise worldwide. The integration of the Company's rapid data
acquisition and review capacity and DLB's integrated clinical research system
allows the Company to offer technological advantages facilitating drug and
medical device development.

Company Services

         The Company's services include centralized diagnostic testing services,
clinical trial and data management, biostatistical services, health care
economics and outcomes research and regulatory affairs services, both in the
United States and internationally. In addition, the Company develops, markets
and supports clinical trial software products.





                                       2

Centralized Diagnostic Testing Services

         Diagnostic tests are employed in clinical trials to measure the effect
of the product on certain body organs and systems, to determine the product's
safety and/or efficacy. Diagnostic testing services provided by the Company
include a variety of diagnostic tests, such as ECGs, Holter monitoring and
clinical laboratory services. These services, which the Company provides on a
centralized basis, are part of most new drug studies. In most cases, the ECG and
transtelephonic monitoring strips, Holter monitoring tapes, imaging and
pulmonary function computer disks and blood and urine samples are delivered to
the Company, which the Company then analyzes or interprets. The Company provides
a broad array of centralized diagnostic testing services, including the
following:

         12-lead Electrocardiography. The ECG provides an electronic map of the
heart's rhythm and structure, and typically is performed in most clinical
trials. ECG strips are measured by the Company's analysts utilizing a digitizing
system, and are then interpreted by a Board-certified cardiologist.

         Holter Monitoring. Holter monitoring is a 24 hour continuous ECG
recording of the heart's rhythm on a cassette tape. The Company has provided
Holter monitoring services since 1977.

         Transtelephonic Monitoring (TTM). TTM measures the electrical activity
of the heart, typically for 5 to 30 seconds. This data is transmitted over
telephone lines by patients carrying a self-activated transmitting device. This
test typically is utilized in trials seeking to identify symptomatic heart
rhythm events.

         Pulmonary Function Testing (PFT). PFT measures the lungs' capacity and
function by having the patient breathe into a spirometer.

         Diagnostic Imaging. This service is used in all clinical imaging
modalities, including standard radiography (e.g., x-rays), contrast-enhanced
radiography (e.g., angiography, studies of the gastrointestinal tract), computed
techniques (including CT scanning and MRI), nuclear medicine techniques and
ultrasonography to determine or confirm the condition of a patient.

         Clinical Laboratory Services. The Company performs centralized
reference testing of blood and urine samples for drug trials.

Clinical Trial Management Services

         The Company offers complete services for the design, performance and
management of clinical trial programs. The results of clinical trials form the
basis on which regulatory approval is granted for pharmaceutical and
biotechnology products and medical devices. The Company's multi-disciplinary
clinical research group and extensive network of consultants examine a product's
pre-clinical and clinical data to design protocols that will evaluate the
product's safety and efficacy. The Company can then manage every aspect of
 



                                       3
<PAGE>

clinical trials, including protocol and database design, site and investigator
recruitment, regulatory initiation, patient enrollment, study monitoring and
data collection, medical services and report writing.


The Company's clinical trial management services include the following:

         Study Protocol Design. The protocol defines the medical issues the
study seeks to examine and the statistical tests that will be conducted to
determine whether the product is safe and effective or, in some pharmacoeconomic
trials, whether it is cost-effective. Detailed in the protocol are: (i) the
number and type of clinical, laboratory and outcomes measures that are to be
tracked and analyzed, (ii) the number of patients required to produce a
statistically valid result, (iii) the period of time over which the patients
must be tracked and (iv) the dosage and frequency of drug administration or the
program of use of the relevant device.

         Site and Investigator Recruitment. The drug or device being tested is
administered to patients by physicians (investigators), at hospitals, clinics or
other locations (sites). Potential investigators are identified by a number of
means. In some cases, the sponsor has pre-selected investigators with whom it
wishes to work. The CRO generally solicits the investigator's participation in
the study. Each trial's success depends on the successful identification and
recruitment of investigators with an adequate base of patients who meet the
requirements of the study protocol. The Company has a database of several
thousand investigators, both within and outside the PREMIER, Inc. alliance of
hospitals. Access to this data allows the Company to readily identify the sites
and investigators able to provide the requisite patient population.

         Patient Enrollment. Investigators find and enroll patients suitable for
each study according to the protocol. The speed with which trials can be
completed is significantly affected by the rate at which patients are enrolled.
Inability to recruit a sufficient number of patients in a timely manner is a
recurring problem and one of the most frequent causes of clinical trial delays,
as well as a major source of cost overruns for the sponsor. The Company believes
that its affiliation with PREMIER, Inc. and the resultant access to PREMIER,
Inc.'s databases should enhance the Company's ability to quickly and
cost-effectively recruit investigators and patients for clinical trials. The
Company believes that its access to PREMIER, Inc.'s patient databases provides a
competitive advantage because it permits the Company to identify more precisely
exclusion and inclusion criteria, thereby maximizing patient recruitment without
jeopardizing patient safety.

         Regulatory Services. Each site is required to document compliance with
regulations governing the conduct of clinical trials, which must be completed
before a trial can be initiated. The PremierResearch * CTIMS (clinical trial
information management system) facilitates this process by providing real-time
tracking of the status of all relevant documents to the Company and to the
client.

         Study Monitoring and Data Collection. As patients are examined and
tests are conducted in accordance with the study protocol, data are recorded on
customized case report forms ("CRFs") and laboratory reports. Traditionally,
these data are assessed at the study site by, specially trained clinical
 



                                       4
<PAGE>

research associates, also known as CRAs or monitors. The CRAs compare the data
to the medical records at the site to reduce the possibility of fraud or error.
The CRA requires site personnel to correct errors to facilitate efficient data
entry. 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. In most CROs, these data are manually entered by personnel
who are not trained to evaluate the content of the data.

         The Company also offers its clients the PremierResearch o Fax system, a
data entry system based on a combination of a commercially available technology
(DataFax TM, Clinical DataFax Systems Inc.) and procedures and software
developed by the Company, which can accelerate the completion, correction and
review of accurate CRF data. The PremierResearch * Fax system permits a CRF to
be filled out by the investigating site, faxed to the Company and reviewed using
the Company's Navigator system within days of a patient's visit. The data from
the fax are automatically downloaded into the Company's database by means of
optical character recognition and the results are carefully checked both by
computer and by trained clinical research personnel. Any errors are compiled and
automatically faxed back to the site for correction. This process allows a large
portion of data errors to be identified and corrected within a week of a given
patient's visit, as opposed to the traditional correction process that typically
requires several weeks to several months. The Company believes that correcting a
large portion of the errors as the trial progresses decreases the time and
expense of clinical data collections and is a significant competitive advantage.

         Medical Services and Report Writing. During the course of a clinical
trial, the Company may provide medical research services, including medical
monitoring of the clinical trials and interpretation of clinical trial results.
In addition, the statistical analysis of the data collected during a trial,
together with other clinical data, are included in a final report generated for
inclusion in a regulatory document. The Company's PremierResearch * CARD
(computer-assisted research and development) technology allows for immediate
correction of data and identification of safety and efficacy issues that may
change the course of the clinical development plan or accelerate its timeline.
The Company believes that this results in improved medical services.

Clinical Data Management and Biostatistical Analysis

         The Company has a history of technological innovation in the provision
of services in drug trials, including creating the first computer-assisted new
drug application ("CANDA") and creating over sixty CANDAs. The Company believes
that its technological expertise provides a competitive advantage in the
provision of clinical data management and biostatistical analysis services.

         Clinical Data Management. The Company's data management professionals
assist in the design of protocols and CRFs, as well as the development of
training manuals for investigational staff to ensure that data are collected in
a systematic format. Once the study protocol has been finalized, CRFs for
recording the desired information must be developed. Different CRFs may



                                       5
<PAGE>

be used at different assessment periods during the course of a trial reflecting
the variety of data collected, and there may be as many as 100 or more CRFs for
each patient in a given study. The Company's technically trained staff format
CRFs compatible with the optical character recognition capabilities of the
Company's PremierResearch * Fax system. CRFs, when utilized with the
PremierResearch * Fax system, increase the accuracy and reduce the time and cost
of data processing during the trial. Databases are designed according to the
analytical specifications of the project and the particular needs of the client.
The Company provides clients with data listings, data review and coding, data
entry, database verification and editing and problem data resolution. In
addition, the Company offers its clients the ability to compile the clinical
data for an electronic regulatory submission, such as a CANDA.

         Biostatistical Analysis. The Company's biostatistics professionals
provide biostatistical consulting, database design, data analysis and
statistical reporting. These professionals develop and review protocols, design
appropriate analysis plans and design report formats to address the objectives
of the study protocol and the client's individual objectives. The Company's
programming staff and biostatisticians work together to perform appropriate
analyses and produce tables, graphs, listings and other applicable displays of
trial results. In addition, biostatisticians can assist clients in government
regulatory proceedings and in legal proceedings.

Health Care Economics and Outcomes Research

         In response to the increased need for pharmacoeconomic and outcomes
data following product approval, the Company offers a variety of health
information services using its expertise in data collection, acquisition,
monitoring, and auditing. The Company designs and conducts pharmacoeconomic,
technology assessment, and clinical outcomes studies for pharmaceutical clients
as well as for PREMIER, Inc. and its affiliated hospitals and institutions.
PREMIER, Inc. and the Company developed an adverse event reporting system
and a drug use information system. The Company plans to expand this activity to
include such services to PREMIER, Inc. members and other health systems.

Regulatory Affairs Services

         The Company provides comprehensive regulatory product registration
services for pharmaceutical, biotechnology and medical device products in North
America, including regulatory strategy formulation, document preparation and
intermediation with the FDA and other regulatory agencies. The Company reviews
published literature, assesses the scientific background of a product and the
competitive and regulatory environment, identifies deficiencies and defines the
steps necessary to obtain registration in the most expeditious manner. Through
this service, the Company helps its clients determine the feasibility of
developing a particular product or product line.



                                       6

Technology

         The Company develops, markets and supports clinical trial software. It
also utilizes its technology to support its services to clients.

         The Company's technology is designed to accelerate product development
and to improve the quality of clinical research by providing superior data
handling that facilitates analysis. Its technology is developed for clinical
research personnel, rather than information technology specialists, enabling
medical reviewers to make timely and accurate decisions during the product
development process. The acquisition of DLB provides the opportunity to extend
the Company's clinical data management expertise worldwide. The integration of
the Company's rapid data acquisition and review capacity and DLB's integrated
clinical data management system allows the Company to offer technological
advantages facilitating drug and medical device development. The Company's
software is available on multiple platforms which facilitates integration with
the wide variety of systems used by its clients.

         The Company believes that its technology is attractive to its clients'
clinical groups, since it includes "user-friendly" tools specifically designed
for clinical research personnel. The Company believes that this provides a
competitive advantage, since this group is influential in CRO selection.

         The Company has a history of technological innovation in the support of
clinical trials, including:


     *    First electronic transfer of centralized diagnostic data, eliminating
          manual key punching (1979).

     *    First multi-site remote data entry system used by the FDA, partially
          replacing site monitoring (1984).

     *    First computer-assisted new drug application, shortening regulatory
          review process (1985). The Company has since filed over 60 full data
          review CANDAs, which it believes constitutes more submissions of this
          kind than all the other major CROs combined.

     *    First NDA Day, a one day intensive session between the FDA and the
          product's sponsor utilizing the interactive features and real-time
          data query capabilities of the CANDA (1988).

     *    First interactive CANDA, providing for the interactive review of
          clinical data by the FDA, further accelerating the regulatory review
          process (1993).


                                       7
<PAGE>

         The Company's technology includes:

         PremierResearch * Navigator. Navigator is the Company's proprietary,
highly interactive software system designed specifically for the review,
analysis and submission of clinical data in the new drug or device application
process. The Company's role in the first CANDA submission, the first interactive
CANDA and the first NDA Day, which are described above, are examples of uses of
the technology that has evolved into Navigator. Navigator is designed to allow
medical and regulatory personnel to interactively review and analyze research
data. It is a "user-friendly" software that permits medical personnel to: subset
data; better analyze and understand clinical trial results, including adverse
events and identification of outliers; graphically display clinical research
data; and respond more quickly to regulatory review questions. The Company
believes that use of its Navigator system speeds both the product development
and regulatory review process, which allows the client to prioritize, change or
potentially terminate development of the product.

         The Company markets the Navigator system for single clinical studies or
single laboratory datasets under the name PremierResearch * CARD
(computer-assisted research and development). Immediate review of clinical
information to detect errors in trial conduct is possible with
PremierResearch * CARD, allowing for rapid correction of data and identification
of safety and efficacy issues that may change the course of the clinical
development plan or accelerate its timeline.

         The Company markets the Navigator system for electronic regulatory
submissions for pharmaceutical clients under the name PremierResearch * CANDA.
PremierResearch * CANDA allows for faster and more effective medical review and
analysis of the submission by the product's sponsor and by regulatory
authorities than conventional tools. Navigator also may be used for the
regulatory submission of biologic and medical device clinical data.

         PremierResearch * Enterprise. Enterprise is a proprietary information
management system that permits efficient and timely delivery of diagnostic and
clinical trial data to the user. Enterprise integrates an entire set of data
from an individual patient in a clinical trial. This information is then
available for on-line review by project management, diagnostic services and
clinical research personnel. Enterprise also provides for flexible encoding and
transfer of the clinical information to the client, based on standardized data
specifications or the client's own specifications. The data can be provided to
the client in a variety of data and media formats, as well as bundled with
Navigator, to allow for immediate interactive review. The Company believes that
Enterprise facilitates and speeds product development by making it easier for
the Company, on behalf of the client, to collect, store, retrieve and utilize
the massive amounts of data traditionally collected in clinical trials.

         PremierResearch * Fax. The Company has developed an overall
data-handling process based on the use of a commercial technology (DataFaxTM,
Clinical DataFax Systems Inc.) supplemented by validation procedures and export
software and procedures allowing integration into the Company's proprietary
Navigator system in an overall system referred to



                                       8
<PAGE>

as the PremierResearch * Fax process. This system receives CRFs, electronically
enters the information into databases, queries the site to correct data errors
and inconsistencies, and compiles the resultant database for rapid export into
the Navigator system for clinical review. The Company believes that the
PremierResearch * Fax system can accelerate the collection and correction of the
CRF, which is filled out by investigators at a site and faxed to the Company
within days of the patient visit. The data from the fax is automatically
downloaded into the Company's database by means of optical character recognition
and the results are carefully checked by both the computer and trained clinical
research personnel. Any errors are compiled and automatically faxed back to the
site for correction. This process allows a large portion of data errors to be
resolved within a week of a given patient's visit, as opposed to the traditional
correction process that typically requires several weeks to several months. The
Company believes that correcting a large portion of errors as the trial
progresses decreases the time and expense of clinical data collection.

         Recorder. Recorder aids clinical data management by unifying and
simplifying case report design, database checking and data quality checking.

         Monitor. Monitor is a comprehensive system and methodology for clinical
development, which supports the planning and management of a development program
and associated studies from Phase I through Phase IV.

         Alert. Alert is a comprehensive system providing a complete solution
for multi-national regulatory compliance for manufacturers of pharmaceuticals,
biologics, consumer health care products and medical devices. Alert provides for
tracking each adverse event through all stages of initial data entry,
assessment, follow-up, and reporting.

Relationship with PREMIER, Inc.

         In September 1995, the Company formed a limited liability company with
PREMIER, Inc., which was owned 65% by the Company, for the provision of clinical
research services. Upon the Company's initial public offering of its Common
Stock in February 1997, PREMIER, Inc.'s interest in the limited liability
company converted into 330,150 shares of the Company's Common Stock.

         PREMIER, Inc. is a voluntary healthcare alliance of more than 1,800
affiliated hospitals and institutions which is the result of the merger of the
Premier Health Alliance, Inc., American Healthcare Systems, Inc. and SunHealth
Alliance, Inc. It is a large voluntary healthcare alliance in the United
States, representing approximately 300,000 hospital beds throughout the United
States. PREMIER, Inc. negotiated, on behalf of the alliance, group purchases of
approximately $6 billion and $10 billion of medical devices, supplies and
pharmaceuticals in 1995 and 1996, respectively.




                                       9
<PAGE>

         The agreement between PREMIER, Inc. and the Company gives the Company
access to information about PREMIER, Inc.'s pharmaceutical contacts as well as
access to PREMIER, Inc.'s databases of patients and physicians for use in
connection with the Company's clinical research studies. The Company, in turn,
has agreed that PREMIER, Inc.'s affiliated hospitals will be utilized as
investigator sites for these studies; however, the Company is not restricted
from using investigator sites outside the PREMIER, Inc. alliance.

         In addition to these contractual provisions, the Company seeks to
leverage its strategic relationship with PREMIER, Inc. in the following ways:

          * PREMIER, Inc. has agreed to introduce the Company, to pharmaceutical
          and device companies that sell or propose to sell products to the
          alliance, and to include a requirement in all of its drug and device
          purchase agreements that such companies will consider utilizing the
          Company's services in their clinical trials.

          * PREMIER, Inc., with the assistance of the Company, is developing a
          trial management organization ("TMO"), for which the Company will be
          the exclusive CRO. The TMO will standardize and coordinate
          investigators, clinical sites and patient recruitment an( form a
          central institutional review board ("IRB"). The Company believes that
          its involvement with this TMO will facilitate the development of
          close working relationships with a large nationwide network of
          investigators, producing improvements in the quality, speed and cost
          of the clinical development process.

          * The Company has access to PREMIER, Inc.'s databases. This access
          permits the Company to independently estimate the available patient
          population in a given area and to assess whether an individual
          investigator has direct access to a suitable patient population.
          Knowing whether a given investigator can supply a sufficient number of
          patients meeting the inclusion and exclusion criteria of a particular
          protocol is an important competitive advantage, since patient
          enrollment is a critical factor in a successful trial. Additionally,
          the Company will use its access to this database to generate
          pharmacoeconomic and outcomes data for its clients.

          * The Company and PREMIER, Inc. have collaborated on the development
          of an adverse events reporting system and drug use information system.
          It is expected that these systems will be used by PREMIER, Inc.'s
          affiliated hospitals and subsequently may be marketed to other
          hospitals.

Sales and Marketing

         The Company's marketing strategy is to focus on prospective clients
whose product development projects are complex. The Company's sales staff
maintains direct contacts and relationships with clients and prospective
clients. The Company believes that a large percentage of its clients have been
referred by others in the industry, and its salespeople seek to foster such
referrals.


                                       10
<PAGE>

         The Company believes that its technology is attractive to the clinical
staff of its clients because of its "user-friendly" tools specifically designed
for clinical research personnel. The Company believes that this provides it with
a competitive marketing advantage, since such personnel are influential in CRO
selection.

         While the Company seeks new clients, it also attempts to increase
repeat business with existing clients by meeting high quality and timely
performance standards and through proactive project management. Approximately
96% of net revenues in 1997 were derived from clients for which the Company
previously has performed services. When the Company increases the amount of
business with an existing client, both benefit from the efficiencies of using
proven systems already in place for study conduct and data delivery.

         The Company intends to use its affiliation with PREMIER, Inc. to gain
access to pharmaceutical, biotechnology and medical device companies that sell
or propose to sell products to PREMIER, Inc. In addition, the acquisition of DLB
will allow the Company to offer software systems integration coupled with
electronic data handling services to provide technological advantages and
end-to-end solutions to clients.

         The Company uses direct mailings of brochures and marketing materials
to existing and prospective clients and advertises in trade journals and similar
publications. The Company also attends and exhibits at selected trade shows in
the United States and Europe.

Clients

         Over the last three years, the Company has provided services to 22 of
the top 25 pharmaceutical companies in the world as ranked by 1996 research and
development expenditures as reported by Med Ad News. During 1997, pharmaceutical
companies accounted for approximately 85% of the Company's net revenues. In the
future, as the Company expands its clinical research services, it expects that
biotechnology and medical device companies will account for a more significant
percentage of its net revenues. During 1997, the Company provided services under
154 contracts to 93 clients, including some of the largest pharmaceutical
companies in the United States, Europe and Japan. In 1995, Pfizer, Inc.,
Bristol-Myers Squibb and Rhone-Poulenc Rorer accounted for approximately 15.0%,
12.1% and 10.0% of the Company's net revenues, respectively. During 1996, Sandoz
Pharmaceuticals Corporation and Zeneca Pharmaceuticals accounted for
approximately 15.3% and 10.1% of the Company's net revenues, respectively.
During 1997, no single client accounted for more than 10% of the Company's net
revenues. The loss of any significant client could have a material adverse
effect on the Company's net revenues.

Forward Load Backlog

         Forward load backlog (also commonly referred to as backlog) consists of
anticipated net revenues from work under letters of intent and contracts that
have been signed but not yet 



                                       11
<PAGE>

completed. Once work under a contract or letter of intent commences, revenues
are generally recognized over the life of the contract, which generally lasts
from one month to two years. Forward load backlog excludes anticipated net
revenues from projects for which the Company has commenced work but for which a
definitive contract or letter agreement has not been executed. Forward load
backlog at December 31, 1997 was approximately $34 million, including
approximately $4 million from DLB.

         The Company believes that its forward load backlog as of any date is
not necessarily a meaningful predictor of future results. Clinical studies under
contracts included in the forward load backlog are subject to termination or
delay. Clients terminate or delay contracts for a variety of reasons including,
among others, the failure of products being tested to satisfy safety
requirements, unexpected or undesirable clinical results of the product, the
client's decision to forego a particular study, insufficient patient enrollment
or investigator recruitment or production problems resulting in shortages of the
drug. Most of the Company's contracts are terminable without cause upon 30 to 90
days notice by the client. The Company typically is entitled to keep any advance
payment and receive certain fees for winding down a study that is terminated or
delayed and, in some cases, a termination fee.

Competition

         The decision of whether to outsource can place the Company in
competition with a client's in-house development group. However, once the
decision is made to outsource, the Company primarily competes against other full
service CROs and, to a lesser extent, universities and teaching hospitals. Some
of these competitors have substantially greater capital, technical and other
resources than the Company. Large CROs with which the Company competes include
ClinTrials Research, Inc., Covance, Inc., IBAH, Inc., Pharmaceutical Product
Development, Inc., PAREXEL International Corporation and Quintiles Transnational
Corporation. CROs generally compete on the basis of experience, medical and
scientific expertise in specific therapeutic areas, the quality of clinical
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 and patients, the ability to integrate information technology with
systems to improve the efficiency of clinical research, an international
presence, financial viability and price. The Company believes that it competes
favorably in all of these areas.

         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 operations. The trend toward CRO industry consolidation has
resulted in heightened competition among the CROs for clients and acquisition
candidates. In addition, consolidation within the pharmaceutical industry, as
well as a trend by pharmaceutical companies to outsource to fewer CROS, has
heightened competition among CROs for contracts from that industry. The Company
believes major pharmaceutical, biotechnology and medical device companies tend
to develop preferred provider relationships with full-service CROs, effectively
excluding smaller CROs from the bidding process. The Company may find reduced
access to certain potential clients due to these arrangements.

                                       12
<PAGE>

         The Company, through DLB, provides software and services to
pharmaceutical, medical device, biotechnology and CRO companies, offering
safety, data management and trial management software. DLB competes primarily
with Fraser Williams and Clinarium in the trial management area. Its data
management competitors include Domain, Oracle Capital and DZS. In addition DLB
vies for business primarily with NetForce and Clinarium in the safety arena.

Government Regulation

         Human pharmaceutical products, biological products and medical devices
are subject to rigorous regulations by the federal government, principally the
FDA, and foreign governments if products are tested or marketed abroad. In the
United States, the FFDCA governs clinical trials and approval procedures as well
as the development, manufacturing, safety, labeling, storage, record keeping and
marketing of pharmaceutical products and medical devices. Biological products
are subject to similar regulation under both the FFDCA and the Public Health
Service Act. Because the Company offers services relating to the conduct of
clinical trials and the preparation of the marketing applications, the Company
is obligated to comply with applicable regulatory requirements governing these
activities, both in the United States and in foreign countries. Requirements
governing these activities vary from country to country.

         In the United States, the Company is subject to inspection by the FDA
to evaluate compliance with applicable requirements governing the conduct of
clinical trials. If the FDA discovers that the Company has violated applicable
requirements relating to the conduct of clinical trials or the preparation of
marketing applications, discussed in more detail below, the FDA may take
enforcement action such as issuance of a Warning Letter; termination of a
clinical study; refusal to approve clinical trial or marketing applications or
withdrawal of such applications; injunction; seizure of investigational
products; civil penalties; or recommending criminal prosecutions. Pursuant to
the FDA's fraud policy, the FDA generally will refuse to approve a pending
clinical trial or marketing application, or withdraw such application, if it
discovers conduct such as submission of fraudulent applications, making untrue
statements of material facts, or giving or promising bribes or illegal
gratuities. The Company also is subject to both mandatory and permissive
debarment by FDA, which would prohibit the Company from assisting in the
submission of abbreviated new, drug applications for generic drugs. Conviction
of criminal conduct relating to the development or approval of an abbreviated
drug application is a prerequisite to such debarment. Such sanctions could have
a material adverse effect on the Company. The Company believes that it is in
material compliance with all applicable governmental regulations.

         The following is a summary of the specific requirements relating to the
clinical testing and approval of drugs, biologics and devices follows.

         Drug Development and Approval in the United States - An Overview

         Drug products marketed in the United States usually require approval by
the FDA before marketing. The steps required before a new prescription drug may
be marketed in the United States include (i) preclinical laboratory and animal
tests; (ii) the submission to the FDA of an Investigational New Drug application
("IND"), which must be evaluated and found acceptable by the FDA before human
clinical trials may commence; (iii) adequate and well-controlled human clinical
trials to establish the safety and effectiveness of the drug; (iv) the
submission of a New Drug Application ("NDA") to the FDA; and (v) FDA approval of
the NDA. The Company's services relate to steps (ii) through (iv) of this
process.

         Clinical trials to evaluate the safety and effectiveness of drugs are
generally conducted in three sequential phases that may overlap. In Phase I
(typically lasting from 6 months to one year), the drug is introduced into a
small number of human subjects, usually healthy volunteers, to determine safety
(adverse effects), dosage tolerance, metabolism, distribution, excretion and
clinical pharmacology. Phase II (typically lasting from one to two years)
involves clinical trials in a limited patient population to determine the
effectiveness of the pharmaceutical for specific targeted indications, to
determine dosage tolerance and optimal dosage and to identify possible adverse
side effects and safety risks. After a compound has been shown in Phase II
trials to have an acceptable safety profile and probable effectiveness, Phase
III trials (typically lasting from 2 to 3 years) are undertaken in an expanded
patient population at multiple clinical sites to further evaluate clinical
effectiveness and safety within an expanded patient population.

         Prior to commencing each phase of a clinical trial, a drug sponsor must
submit an IND application to the FDA. The IND application must contain, among
other things, protocols for each study; a description of the composition,
manufacture, and control of the drug substance and the drug product; information
about preclinical pharmacological and toxicological studies of the drug; and a
summary of previous human experience with the investigational drug. Unless the
FDA objects, the IND will become effective 30 days following its receipt by the
FDA. If the FDA has concerns about the proposed clinical trial, it may delay the
trial and require modifications to the trial protocol prior to permitting the
trial to begin. In addition, all clinical trials of new drugs must obtain
approval of the institutional review board ("IRB") at each institution at which
the trial is conducted. The IRB reviews the study to verify the method of
experimentation and safety, and to ensure that subjects give their informed
consent to participate in the clinical trial.

         When results from a Phase II or Phase III study show promise in the
treatment of a serious or immediately life-threatening disease in patients for
whom no comparable or satisfactory alternative drug or other therapy exists, the
FDA may allow the manufacturer to make the new drug available to a larger number
of patients through the regulated mechanism of 



                                       14
<PAGE>

a treatment IND. Although less scientifically rigorous than a controlled
clinical trial, the treatment IND facilitates availability of promising drugs to
ill patients prior to general marketing and also allows sponsors to obtain
additional data on the drug's safety and effectiveness. In general, treatment
use of an investigational drug is conditioned upon compliance with safeguards of
the IND process such as informed consent, IRB approval, and other requirements.

         Once a clinical trial with proper IRB and IND approval is commenced,
the conduct of the clinical trial is governed by extensive FDA regulations.
Clinical trial sponsors (i.e., the persons who initiate the trials but do not
actually conduct the investigations) are responsible for the selection of
qualified investigators, providing investigators with protocols and other
necessary information, monitoring the investigation, reporting changes in study
protocol to the FDA, reporting to the FDA and investigators safety reports of
serious and unexpected adverse experiences associated with use of the drug, and
maintaining records concerning the study. To the extent that the Company
performs these functions on behalf of a drug sponsor, the Company must comply
with these requirements.

         Upon completion of clinical trials that demonstrate the safety and
efficacy of a new drug, a drug sponsor must submit an NDA and obtain FDA
approval of an NDA prior to marketing the drug. The NDA must include information
pertaining to the composition, manufacture, and specification of the drug
substance; a description of the preclinical studies; a description of the human
pharmacokinetic data and human bioavailability data; descriptions of clinical
investigations; a statistical evaluation of the clinical data; and proposed
labeling. Submission of an NDA does not assure the FDA approval for marketing.
The application review process generally takes at least two to three years to
complete, and the FDA may require additional data or other studies during the
course of its review. Notwithstanding the submission of such data, the FDA
ultimately may decide that the application does not satisfy its regulatory
criteria for approval. Finally, the FDA may require additional clinical testing
following NDA approval to confirm safety and efficacy (Phase IV clinical tests).
No assurance exists that clinical studies conducted will provide sufficient
information to support the filing of an NDA.

         Clinical trials may be conducted outside of the United States without
an IND. The FDA will accept data from such foreign clinical trials to support
clinical investigations in the United States and/or approval of an NDA only if
the agency determines that the trials are well-designed, well-conducted,
performed by qualified investigators, and conducted in accordance with
internationally recognized ethical principles.

         Less extensive approval requirements can apply to generic drugs.
Abbreviated requirements are applicable to drugs that are, for example, either
bioequivalent to brand name "pioneer" drugs, or otherwise similar to pioneer
drugs, such that all the safety and efficacy studies previously conducted on the
pioneer product need not be repeated for approval. Changes in approved drug
products, such as in the delivery system, dosage form or strength, can also be
the subject of abbreviated application requirements.

         Biological Product Development and Approval in the United States - An
Overview

         Like drugs and medical devices, biological products (i.e., those
derived from living materials of humans, plant, animals or microorganisms, such
as vaccines) are subject to extensive regulation by FDA. Biological products are
regulated primarily under the Public Health Service Act, but are also subject to
regulation under the FFDCA.

         While some biological products may be approved for marketing via a new
drug application ("NDA"), most manufacturers must obtain two licenses from FDA
prior to marketing a biological product: a license for the manufacturing
establishment, and a product license. In order to obtain a product license, a
manufacturer must obtain FDA approval of a product license application ("PLA").
Similar to an NDA, a PLA must contain the following information: nonclinical and
clinical data demonstrating the product's safety, purity and potency; a
description of the manufacturing methods; data regarding the product's
stability; test results for the lots represented by the submitted samples, and
samples of the product and its labeling.

         The sponsor of a clinical trial involving a biological product must
file an IND with FDA, unless the product is exempt from such requirement. Once
the IND becomes effective, the conduct of the clinical trial is governed by the
same regulatory requirements governing drug clinical trials. Thus, to the extent
that the Company performs these functions on behalf of the biological product
sponsor, the Company must comply with these requirements.

         Device Development and Approval in the United States - An Overview

         The FFDCA and regulations thereunder require that, unless exempted by
regulation, all products meeting the statutory definition of "device" receive
the FDA clearance of a premarket notification (510(k)) submission or FDA
approval of a premarket approval ("PMA") application prior to marketing in the
United States. Generally, devices are distinguished from drugs through the
characteristic of acting or achieving their effect through means other than
pharmacologic action.

         The FDA categorizes medical devices into three regulatory
classifications (Class I, II, and III) on the basis of controls deemed
reasonably necessary to ensure their safety and effectiveness. Class I devices
are subject to general controls (e.g., labeling, premarket notification, and
adherence to good manufacturing practice regulations for medical devices), and
Class II devices are subject to general controls and special controls (e.g.,
performance standards, postmarket surveillance, patient registries and FDA
guidelines). Class III devices (generally including life-sustaining,
life-supporting, or implantable devices, or new devices that have been found not
to be substantially equivalent to a legally marketed predicate device) are those
which must receive premarket approval ("PMA") prior to marketing.



                                       16
<PAGE>

         Before a new device can be introduced into the market, the manufacturer
must generally obtain marketing clearance or approval through either a 510(k)
premarket notification or a PMA. A 510(k) clearance will be granted if the
submitted information establishes that the proposed device is "substantially
equivalent" to a legally marketed "predicate" device (i.e., a Class I or II
medical device, or to a Class III medical device for which the FDA has not
called for a PMA). The 510(k) must include, among other information, proposed
labeling and advertisements; data demonstrating substantial equivalence to a
claimed predicate; and any additional information regarding the device requested
by the FDA that is necessary to make a finding as to substantial equivalence to
a predicate device. The FDA can require clinical studies to demonstrate that a
device is as safe and effective as the predicate device. The FDA recently has
been requiring a more rigorous demonstration of substantial equivalence than in
the past. It generally takes from four to twelve months from submission of a
510(k) to obtain 510(k) clearance, but it may take longer. The FDA may determine
that a proposed device is not substantially equivalent to a legally marketed
device, or that additional information or data are needed before a substantial
equivalence determination can be made.

         If a manufacturer cannot establish that a proposed device is
substantially equivalent to a legally marketed predicate device, the
manufacturer must seek premarket approval of the proposed device from the FDA
through the submission of a PMA application. A PMA application must be supported
by extensive data, including nonclinical laboratory studies or animal testing;
clinical trial data; and a bibliography of all published reports reasonably
known to the manufacturer concerning safety or effectiveness. In addition, the
PMA must include a full description of the device and its components; the
principle of operation of the device; a full description of the methods,
facilities and controls used for manufacturing, processing, packing, storage
and, where appropriate, installation; and proposed labeling. Upon receipt of a
PMA application, the FDA makes a threshold determination as to whether the
application is sufficiently complete to permit a substantive review. If the FDA
determines that the PMA application is sufficiently complete to permit a
substantive review, the FDA will accept the application for filing.

         Once the submission is accepted for filing, the FDA begins an in-depth
review of the PMA. An FDA review of a PMA application generally takes one to two
years from the date the PMA application is accepted for filing, but may take
significantly longer. The review time is often significantly extended by the FDA
asking for more information or clarification of information already provided in
the submission. During the review period, an advisory committee, typically a
panel of clinicians, will likely be convened to review and evaluate the
application and provide recommendations to the FDA as to whether the device
should be approved. The FDA is not bound by the recommendations of the advisory
panel. If the FDA's evaluation of the PMA application is favorable, the FDA will
issue either an approval letter or an approvable letter, which usually contains
a number of conditions which must be met in order to secure final approval of
the PMA. When and if those conditions have been fulfilled to the satisfaction of
the FDA, the FDA will issue a PMA approval letter, authorizing marketing of the
device for certain indications. If the FDA's evaluation of the PMA application
is not favorable, the FDA will deny approval of the PMA application or issue a



                                       17
<PAGE>

"not approvable" letter. The FDA may also determine that additional clinical
trials are necessary, in which case PMA approval may be delayed for several
years while additional clinical trials are conducted and submitted in an
amendment to the PMA.

         Human clinical trials are always required to support a PMA application,
and may be required to support a 510(k) submission. If the device involved
presents a "significant risk" to the patient, the clinical trial sponsor must
obtain IRB approval for the study and must file an investigational device
exemption ("IDE") application with the FDA prior to commencing human clinical
trials. The IDE application must include reports of prior clinical and
nonclinical investigations of the device; an investigational plan; a description
of the methods, facilities, and controls used for the manufacture, processing,
packing, storage, and, where appropriate, installation of the device;
information concerning the investigators participating in the study and the
IRB's that approved the study; copies of labeling; copies of forms to be
provided to subjects to obtain informed consent; and other relevant information
requested by the FDA. As with IND applications, the IDE will become effective 30
days following its receipt by the FDA unless the FDA objects to the application.
If the FDA has concerns about the proposed clinical trial, it may delay the
trial and require modifications to the trial protocol prior to permitting the
trial to begin. Clinical trials involving a device that presents a
"nonsignificant risk" to the patient may begin after the sponsor has obtained
approval by one or more appropriate IRB'S, but not the FDA. Such investigations
are, nevertheless, subject to informed consent requirements, monitoring by the
sponsor, and record keeping requirements.

         As discussed with respect to clinical studies involving drugs, the FDA
strictly regulates the conduct of all clinical trials involving medical devices,
regardless of whether the clinical trial is conducted under an IDE. The sponsor
of a clinical study involving a device is responsible for ensuring that proper
IRB and/or FDA approval is obtained prior to commencing the study, selecting
qualified investigators and informing investigators of all necessary
information, monitoring the investigation, informing the IRB and the FDA about
significant new information pertaining to the investigation, and maintaining
accurate and current records concerning the investigation. The sponsor must
evaluate unanticipated adverse effects and terminate the study if it presents an
unreasonable risk to subjects. To the extent that the Company performs these
functions on behalf of a investigational device sponsor, the Company must comply
with these requirements.

         The FDA will accept foreign clinical studies involving devices that are
not conducted under an IDE if the data are valid and the investigator has
conducted the studies in conformance with the "Declaration of Helsinki" or the
laws and regulations of the country in which the research is conducted,
whichever accords greater protection to human subjects. Foreign clinical data
that meets these requirements may form the sole basis for PMA approval if the
foreign data are applicable to the United States population and medical
practice, studies were performed by clinical investigators of recognized
competence, and (if necessary) the FDA validates the data through an on-site
inspection or other means.

         CLIA Requirements - An Overview

         The Company's clinical laboratory services are subject to the
requirements of the Clinical Laboratory Improvement Amendments of 1988 ("CLIA").
This law requires all laboratories to meet specified standards in the areas
including personnel qualification, administration, participation in proficiency
testing, patient test management, quality control, and quality assurance. In
addition, laboratories such as the Company's clinical laboratory must obtain
appropriate certification under CLIA. The Company has obtained such
certification for its clinical laboratory.

         Under CLIA, the Company's clinical laboratory is subject to inspection
by the United States Department of Health and Human Services or a designee.
Violations of the CLIA requirements may result in sanctions including
suspension, limitation, or revocation of certification; enjoinment of laboratory
activities; civil money penalties; or criminal prosecution for intentional
violations. There can be no assurance that the regulations under, and future
administrative interpretations of, CLIA will not have an adverse impact on the
Company's services in this area.

         Foreign Regulatory Requirements

         The Company also is subject to foreign regulatory requirements
governing clinical trials and product approval requirements. Whether or not the
FDA approval has been obtained to conduct a clinical trial or market an
FDA-regulated product, approval by comparable regulatory authorities in foreign
countries usually must be obtained to conduct such activities in those
countries.

Potential Liability and Insurance

         The Company attempts to manage its risk of liability for personal
injury or death to patients from administration of products under study through
contractual indemnification provisions with clients and through insurance
maintained by the Company and its clients. Contractual indemnification generally
does not protect the Company against certain of its own actions, such as
negligence. The terms and scope of such indemnification vary from client to
client and from trial to trial. Although most of the Company's clients are
large, well capitalized companies, the financial viability of these
indemnification provisions cannot be assured. Therefore, the Company bears the
risk that the indemnifying party may not have the financial ability to fulfill
its indemnification obligations. The Company also maintains professional
liability insurance in the amount of $1 million per claim and in the aggregate
and an umbrella policy of $3 million. The Company could be materially and
adversely affected if it were required to pay damages or incur defense costs in
connection with a claim that is beyond the scope of an indemnity provision or
beyond the scope or level of insurance coverage maintained by it or the client
or where the indemnifying party does not fulfill its indemnification
obligations.

Intellectual Property

         The Company's services have been enhanced by significant investment in
information technology. The Company's information services group is committed to
achieving operating efficiencies through technical advances. The Company has
developed certain computer software and technically derived procedures that it
seeks to protect through a combination of contract law, trademarks, and trade
secrets. Although the Company does not believe that its intellectual property
rights are as important to its results of operations as are such factors as
technical expertise, knowledge, ability and experience of the Company's
professionals, the Company believes that its technical capabilities provide
significant benefits to its clients.

Employees

         At December 31, 1997, the Company had 201 employees. At its US
locations the Company had 173 employees (158 full-time, 15 part-time). At its UK
locations the Company had 28 employees (all full-time). On December 31, 1997, 30
employees held M.D., Ph.D. or other masters or post-graduate degrees. The
Company believes that its relations with its employees are good.


ITEM 2. PROPERTIES

         The Company leases all of its facilities. The Company's principal
offices are located in Philadelphia, PA, where it leases approximately 35,000
square feet under a lease expiring in 2003. This facility is owned by UM
Holdings, Ltd. See "Certain Relationships." The Company also maintains an office
of approximately 9,000 square feet in Peterborough, UK. The Company's DLB
operations are located in Bridgewater, New Jersey, where it leases approximately
10,600 square feet and in Cambridge, UK, where it leases 3,500 square feet. The
Bridgewater and Cambridge leases expire in 1999 and 2002, respectively. The
Company believes that the leases generally reflect market rates in their
respective geographic areas.


ITEM 3. LEGAL PROCEEDINGS

         The Company is involved in legal proceedings from time to time in the
ordinary course of its business. Management believes that none of these legal
proceedings will have a material adverse effect on the financial condition or
results of operations of the Company.

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

         The Company did not submit any matters during the fourth quarter of the
year covered by this Report to a vote of the security holders through the
solicitation of proxies or otherwise.


SPECIAL ITEM. EXECUTIVE OFFICERS OF REGISTRANT

         Officers are elected by the Board of Directors and serve at the

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

         The Company's Common Stock has been traded on The Nasdaq National
Market System since February 4, 1997, under the symbol "PRWW". Before February
1997, no established public trading market existed for the Company's Common
Stock. Below is the range of high and low sales information for the Common Stock
for the following quarters as quoted on The Nasdaq National Market System:

Calendar Period                                        High               Low
- ----------------                                     --------          --------
First Quarter (February 4 - March 31)                $26.250           $13.125
Second Quarter                                        17.000             5.375
Third Quarter                                         12.000             7.625
Fourth Quarter                                        14.250             6.250

         Prior to the Company's initial public offering of its common stock in
February 1997, the Company made net distribution to UM Holdings, Ltd. for 1996
of $1,212,000. No distributions were made to UM Holdings, Ltd. in 1997. The
present policy of the Company is to retain future earnings to fund the
development and growth of its business and therefore does not anticipate paying
cash dividends in the foreseeable future.

         As of March 26, 1998, there were approximately 1,400 holders of record
of the Company's Common Stock.

         In its initial public offering, the Company sold 2,206,250 shares of
Common Stock (including over-allotments), pursuant to its Registration Statement
on Form S-1, File No. 333-17001 (the "Registration Statement"), which was
declared effective by the Securities and Exchange Commission on February 3, 1997
(the "Effective Date"). The gross proceeds to the Company from the IPO were
approximately $37,506,000, and, after underwriting discounts and commissions,
expenses paid to or for the benefit of underwriters, and other costs of the IPO,
net proceeds to the Company were approximately $34,182,000.

         From the Effective Date to December 31, 1997, the Company purchased
approximately $1,300,000 of property and equipment, and used approximately
$1,000,000 for working capital, $17,100,000 for short-term investments and
$8,700,000 for the purchase of DLB.

         None of the foregoing payments resulted in direct or indirect payments
(i) to directors or officers of the Company, nor their associates, (ii) to
persons owning 10% or more of the Common Stock of the Company, nor (iii) to
affiliates of the Company.

         The Company's use of proceeds does not represent a material change in
the use of proceeds described in the Prospectus contained within the
Registration Statement.

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

Overview

         The Company is a clinical research organization providing a broad range
of integrated product development services on a global basis to its clients in
the pharmaceutical, biotechnology and medical device industries. The Company's
services include centralized core laboratory testing (which includes diagnostic
services that consist primarily of ECG reading and blood laboratory services),
clinical trial management, clinical data management, bio-statistical analysis,
health care economics and outcomes research and regulatory affairs services. In
addition, the Company develops, markets and supports clinical trial software
products.

         The Company's centralized core laboratory services are on a
fee-for-service basis and generally have terms from one month to two years. A
portion of the Company's fee typically is paid upon contract execution as a
non-refundable up-front payment, with the remaining amounts billed monthly.
Clinical research service contracts are generally fixed priced, with certain
variable components, and range in duration from a few months to two years. A
portion of the Company's fee typically is paid upon contract execution



                                       25
<PAGE>

as a non-refundable up-front payment, with the balance billed in accordance with
the contract terms. The Company's contracts generally may be terminated with or
without cause on 30 to 90 days notice. Clients terminate or delay contracts for
a variety of reasons, including, among others, the failure of the product(s)
being tested to satisfy safety or efficacy requirements; unexpected or undesired
clinical results of the product; the client's decision to forego a particular
study; insufficient patient enrollment or investigator recruitment, and
production problems resulting in shortages of required supplies. Revenues from
clinical trial software and services are derived primarily from software license
fees and software maintenance and support services.

         Revenues from core laboratory service contracts generally are
recognized on a per procedure basis as the work is performed. For the years
ended December 31, 1997, 1996 and 1995, the core laboratory service revenues
represented 48.7%, 78.8% and 65.1%, respectively, of total net revenues.
Revenues from clinical research service contracts generally are recognized on a
percentage of completion basis as work is performed. The Company regularly
subcontracts with third-party investigators in connection with clinical trials
and with other third-party providers for specialized services. These and other
reimbursable costs are paid by the Company and reimbursed by clients and, in
accordance with industry practice, are included in revenues. Since reimbursed
costs may vary significantly from contract to contract and are not meaningful
for analyzing trends in revenues, they are included in gross revenues but
excluded from net revenues. Revenues from clinical trial software licenses are
recognized upon shipment of the software and related documentation and customer
acceptance. Revenues from software maintenance and continuing support contracts
are recognized on a straight-line basis over the period in which the software
maintenance and continuing support is provided. Revenues from consulting and
training services are recognized when the services are performed.

         Consistent with industry practice, the Company considers net revenues
its primary measure of growth. The Company has had, and expects to continue to
have, certain clients, which will generate at least 10% of the Company's overall
revenue. The Company believes that such concentration of business is not
uncommon in the clinical research industry.

         The Company's forward load backlog consists of anticipated core
laboratory, clinical research and software net revenues from work under letters
of intent and contracts that have been signed but not yet completed. At December
31, 1997, the backlog was approximately $34 million, including approximately $4
million from DLB. The Company believes that its backlog as of any date is not
necessarily a meaningful predictor of future results because backlog can be
affected by a number of factors, including size and duration of contracts, some
of which are performed over several years. The Company recognizes revenue over
the duration of the contract as services are provided. No assurance can be given
that the Company will be able to fully realize all of its backlog as net
revenues.

         The Company conducts operations on a global basis, with offices in the
United States and United Kingdom. For the years ended December 31, 1997, 1996
and 1995, the Company's European net revenues represented 6.9%, 14.9% and 9.8%,
respectively, of total net revenues.

Results of Operations

Year ended December 31, 1997, compared to the year ended December 31, 1996

         Net revenues decreased $1.1 million or 7.3% to $14.2 million for the
year ended December 31, 1997, compared to the year ended December 31, 1996. The
decrease was primarily due to a $5.1 million decrease in diagnostic service
revenues for the year ended December 31, 1997. Diagnostic service revenues
primarily decreased as the result of several significant ECG contracts, which
were ongoing in 1996, being completed in early 1997, with a low level of new ECG
contracts initiated in 1997. Partially offsetting the decrease in diagnostic
service revenues, were increases in Phase I revenues and clinical trial and data
management revenues of $0.9 million and $2.4 million, respectively. The increase
in Phase I revenues was the result of several large contracts that were
conducted in 1997. The clinical trial and data management revenue growth was
attributable to the Company's increased service capabilities developed during
1997. Revenues for the year ended December 31, 1997, were also increased by $0.4
million in connection with a payment received in the first quarter for a
licensing agreement termination.

         Effective October 31, 1997, the Company acquired DLB Systems, Inc.
(DLB) (see Liquidity and Capital Resources). Included in the Company's 1997 net
revenues are DLB revenues of $0.8 million.

         Direct costs increased $0.9 million or 14.0% to $7.2 million for the
year ended December 31, 1997, compared to the year ended December 31, 1996. As a
percentage of net revenues, direct costs increased to 50.6% in 1997, compared to
41.1% in 1996. The increase was primarily attributable to increased costs
incurred in connection with the growth in Phase I and clinical trial and data
management revenues. Such costs increased $.6 million and $1.3 million,
respectively, and were comprised primarily of direct labor. The direct costs
associated with revenues from DLB accounted for $0.4 million of the year-to-year
increase. Partially offsetting these increases was a $1.4 million decline in
direct costs of diagnostic services from $4.4 million for the year ended
December 31, 1996 to $3.0 million for the year ended December 31, 1997. Prior to
1997, the Company paid ECG reading analysis fees to a professional corporation
owned by Joel Morganroth, MD, the Company's President and Chief Executive
Officer. The Company and Dr. Morganroth entered into new employment and
consulting agreements, effective January 1, 1997, whereby Dr. Morganroth no
longer receives ECG reading fees. During 1996, Dr. Morganroth was paid $1.8
million for ECG reading services compared with $0.1 million in 1997 under the
terms of the consulting agreement. See Notes 8 and 10 of Notes to Consolidated
Financial Statements.

         Selling, general and administrative expenses increased $3.1 million or
46.3% to $9.9 million for the year ended December 31, 1997, compared to the year
ended December 31, 1996. During 1997, the Company initiated new sales and
marketing campaigns, doubled the size of the direct sales force, increased its
commitment to its proprietary software systems and expanded its service
capabilities through increased personnel. In addition, the acquisition of DLB
added $0.4 million to the overall growth in selling, general and administrative
expenses. As a percentage of net revenues, selling, general and administrative
expenses were 70.1% for the



                                       27
<PAGE>

year ended December 31, 1997, compared to 44.4% for the year ended December 31,
1996.

         Depreciation and amortization expense for the year ended December 31,
1997 was comparable to the year ended December 31, 1996, at $0.7 million.

         In connection with the DLB acquisition, the Company assigned $7.9
million of the total purchase price to in-process research and development and
such amount was written-off as a one-time charge ($0.71 per share) in the fourth
quarter of 1997.

         Other income of $1.3 million during the year ended December 31, 1997,
resulted primarily from income earned on investment of the net proceeds of the
Company's initial public offering in February 1997.

         The Company had an income tax benefit of $4.0 million for the year
ended December 31, 1997 compared to a tax provision of $0.8 million for the year
ended December 31, 1996. The Company's effective income tax rate for the year
ended December 31, 1997, was 39.3%, compared to 41.9% for the year ended
December 31, 1996. The rate decrease in 1997, was primarily the result of
investment interest earned in 1997 that was not taxable for state purposes. The
1997 tax benefit included the recognition of a significant deferred tax asset,
primarily due to the write-off of in-process research and development and net
operating loss carry-forwards. See Note 7 of Notes to Consolidated Financial
Statements.

Year ended December 31, 1996, compared to the year ended December 31, 1995

         Net revenues increased $3.2 million, or 26.4%, to $15.3 million for the
year ended December 31, 1996, compared to the year ended December 31, 1995. The
increase was directly attributable to a significant increase in the volume of
diagnostic services. Diagnostic service revenues increased $4.2 million or 53.2%
for the year ended December 31, 1996, compared to the prior year, and included
an increase of $1.1 million in the net revenues of the Company's UK subsidiary.
Offsetting the increase in diagnostic service revenues was a $0.9 million
decrease in CANDA revenues and a $0.2 million decrease in Phase I clinical
trials revenues. The decrease in CANDA revenues was due to fewer CANDA services
being performed for clients during the year resulting from the Company's larger
pharmaceutical clients' ability to perform such services in-house and a reduced
pressure to file CANDAs stemming from a reduction in FDA review time. The
Company believes that the decrease in Phase I revenues primarily was caused by a
delay in the commencement of domestic Phase I trials in 1996 as a result of
certain consolidations occurring in the pharmaceutical industry. The Company
believes that these factors are unlikely to cause a continuing decrease in Phase
I revenues, but that this business area is likely to experience slower growth
than other sectors of its business.

         Direct costs increased $2.2 million, or 53.7%, to $6.3 million for the
year ended December 31, 1996, compared to the year ended December 31, 1995. As a
percentage of net revenues, direct costs increased to 41.1% in 1996, compared to
34.2% in 1995. The increase primarily was attributable to increased consulting
fees paid to the Company's President in



                                       28
<PAGE>

connection with medical interpretations for diagnostic tests, in addition to
general increases in connection with the increase in diagnostic services. The
consulting fees for medical interpretations increased from $0.8 million in 1995
to $1.8 million in 1996. The Company and the President have entered into a new
consulting agreement that discontinued such variable fees effective January 1,
1997.

         Selling, general and administrative expenses increased $0.4 million, or
6.3%, to $6.8 million for the year ended December 31, 1996, compared to the year
ended December 31, 1995. As a percentage of net revenues, selling, general and
administrative expenses decreased from 52.8% in 1995 to 44.4% in 1996. The
dollar increase resulted from additional costs, primarily payroll, required to
build the clinical trials management business. The reduction as a percentage of
net revenues was due to the relatively fixed nature of the expenses, the
Company's focus on monitoring support costs and efficiencies gained through
increased volume.

         Depreciation and amortization decreased $0.3 million, or 30.0%, to $0.7
million for the year ended December 31, 1996, compared to the year ended
December 31, 1995. As a percentage of net revenues, depreciation and
amortization decreased from 8.4% in 1995 to 4.6% in 1996. The decrease primarily
was the result of the Company's continuing transition from more expensive
mainframe computers to less expensive personal and server-based computers.

         The Company's effective income tax rate for the year ended December 31,
1996, was 41.9%, compared to 43.2% for the year ended December 31, 1995. The
rate decrease in 1996 was the result of a higher proportion of non-deductible
expenses as a percentage of net income in 1995 compared to 1996.

Liquidity and Capital Resources

         The clinical research industry generally is not capital intensive. The
Company's principal cash needs relate to funding receivables as client payments
generally lag 45 to 75 days after the invoice date. The Company historically has
funded the increase in receivables through cash generated from operations.

         In February 1997, the Company completed the initial public offering of
its common stock, which resulted in proceeds from the offering, net of expenses,
of $34.2 million. As of December 31, 1997, the Company had cash and cash
equivalents of $4.7 million and short-term investments of $17.1 million. The
Company generally places its investments in A1P1 rated commercial bonds and
paper, municipal securities and certificates of deposit with maturities of less
than one year.

         For the year ended December 31, 1997, the Company used cash in
operating activities of $3.8 million compared to cash provided by operations of
$3.0 million during the year ended December 31, 1996. The decrease in operating
cash flow was due primarily to the Company's net loss of $6.2 million, an
increase in net deferred income tax assets of $4.1 million and from changes in
the working capital accounts, including a $1.3 million increase in accounts
receivable. The above were partially offset by the $7.9 million write-off of
in-process research and development.



                                       29
<PAGE>

         During the year ended December 31, 1997, the Company purchased $1.5
million of property and equipment and used $17.1 million of the proceeds from
the public offering to purchase short-term investments. On June 30, 1997, the
Company paid $1.0 million to acquire a 14% equity interest in DLB. Effective
October 31, 1997, the Company purchased substantially all of DLB's assets for an
additional $6.5 million plus the assumption of certain liabilities. The total
purchase price of DLB was $8.7 million.

         The Company has a line of credit arrangement with First Union National
Bank totaling $3.0 million. At December 31, 1997, the Company had no outstanding
borrowings under the line.

         The Company expects that existing cash and cash equivalents, short-term
investments, cash flow from operations and borrowings under its line of credit
will be sufficient to meet its foreseeable cash needs for at least the next
year. However, there may be acquisition and other growth opportunities that
require additional external financing and the Company may from time to time seek
to obtain additional funds from the public or private issuances of equity or
debt securities. There can be no assurance that such financings will be
available or available on terms acceptable to the Company.

Recent Events

         On February 13, 1998, the Company entered into a non-binding letter of
intent to purchase substantially all of the assets, the ongoing business
operations and assume certain liabilities of South Florida Kinetics, Inc., doing
business as South Florida Bioavailablitiy Clinic (SFBC). The letter of intent
was subject to various contingencies including due diligence by the Company and
execution and delivery of a definitive purchase agreement. Due diligence is
continuing and, at the time of this report, no definitive acquisition agreement
has been executed. Accordingly, there can be no assurances that the transaction
will be consummated.

Year 2000

         Many computer systems were not designed to handle any dates beyond the
year 1999, and therefore, computer hardware and software will need to be
modified prior to the year 2000 in order to remain functional. The current
versions of the Company's software products support dates in the year 2000 and
beyond. In the event that any of the Company's significant suppliers or
customers do not successfully achieve Year 2000 compliance on a timely basis,
the Company's business or operations could be adversely affected. The Company
has evaluated its information technology infrastructure and has made or is in
the process of making modifications for Year 2000 compliance. The Company does
not expect future costs to modify its information technology infrastructure to
be material to its financial condition or results of operations.

Inflation

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

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Premier Research Worldwide, Ltd.:

We have audited the accompanying consolidated balance sheets of Premier Research
Worldwide, Ltd. and subsidiaries as of December 31, 1997 and 1996, 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, 1997.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.

We conducted our audits 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 provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Premier Research Worldwide,
Ltd. and subsidiaries, as of December 31, 1997 and 1996, and the results of
their operations and their cash flows for each of the years in the three-year
period ended December 31, 1997, in conformity with generally accepted accounting
principles.

Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedule listed in the Index to
Consolidated Financial Statements and Schedule is presented for purposes of
complying with the Securities and Exchange Commission's rules and is not part of
the basic financial statements. This schedule has been subjected to the auditing
procedures applied in our audits of the basic financial statements and, in our
opinion, fairly states, in all material respects, the financial data required to
be set forth therein in relation to the basic financial statements taken as a
whole.

                PREMIER RESEARCH WORLDWIDE, LTD. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. BACKGROUND AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Background

Premier Research Worldwide, Ltd. (the "Company"), a Delaware corporation, is a
clinical research organization providing a broad range of integrated product
development services on a global basis to its clients in the pharmaceutical,
biotechnology and medical device industries. The Company's services include
centralized core laboratory testing, clinical trial management, clinical data
management, bio-statistical analysis, Phase I clinical research, health care
economics and outcomes research and regulatory affairs services. In addition,
the Company develops, markets and supports software products used in the
management of clinical trials. The Company also has a wholly-owned operating
subsidiary in the United Kingdom (UK).

For periods prior to June 1, 1994, the Company's business operated as direct or
indirect subsidiaries or as divisions of UM. Effective June 1, 1994, the net
assets and operations of the division were transferred to the Company by UM. The
transfer was recorded as a capital contribution of the carrying value of the
division's net assets.

Initial Public Offering

The Company completed an initial public offering of its common stock effective
February 3, 1997. The Company sold 2,750,000 shares of common stock at an
initial public offering price of $17.00, of which 2,000,000 shares were issued
and sold by the Company and 750,000 shares were sold by UM Holdings, Ltd. (UM).
Additionally, 412,500 shares of common stock were purchased at $17.00 per share
by the underwriters, upon the exercise of an over-allotment option, of which
206,250 shares were purchased from the Company and 206,250 shares were purchased
from UM. The net proceeds to the Company, after deducting underwriting discounts
and expenses, were approximately $34.2 million.


Principles of Consolidation

The accompanying consolidated financial statements include the accounts of the
Company, its subsidiaries and Premier Research LLC prior to the Company's
initial public offering (See Note 6). All significant intercompany accounts and
transactions have been eliminated.

Use of Estimates

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

Revenues

Revenues from clinical research services are recorded when services are
rendered. Revenues under certain clinical research service contracts are
recognized under the percentage-of-completion method and include a proportion of
the revenues expected to be realized on the contract in the ratio of costs
incurred to estimated total costs. Such contracts are generally completed within
a few months to two years. A provision for the loss on a contract is made when
current estimates indicate a total contract loss. The Company often receives
non-refundable deposits from its customers that are recorded as deferred
revenues in the accompanying balance sheets. Software license revenues are
recognized upon shipment of the software and related



                                      F-7
<PAGE>

documentation and customer acceptance. Revenues from maintenance and customer
support contracts are recognized on a straight-line basis over the term of the
contract, generally 12 months. Revenues from related training and consulting
services are recognized as services are performed. Revenues for the year ended
December 31, 1997 include $416,000 recognized in connection with a license
agreement termination.

Cash and Cash Equivalents

Until 1996, UM maintained a centralized cash management function for its
subsidiaries, including the Company. Settlement of all cash disbursement and
collection transactions by UM on behalf of the Company have been recorded
through equity.

The Company considers cash on deposit with financial institutions and all highly
liquid investments purchased with an original maturity of three months or less
to be cash equivalents. At the balance sheet dates, cash equivalents consisted
primarily of investments in money market funds, municipal securities and bonds
of government sponsored agencies.

Short-Term Investments

At December 31, 1997, short-term investments consisted of commercial bonds and
paper, municipal securities, certificates of deposit and bonds of government
sponsored agencies with maturities of less than one year. Pursuant to Statement
of Financial Accounting Standards (SFAS) No. 115, "Accounting for Certain
Investments in Debt and Equity Securities", available-for-sale securities are
carried at fair value, based on quoted market prices, with unrealized gains and
losses, net of tax, reported as a separate component of stockholders' equity.
The Company has classified all of its short-term investments at December 31,
1997 as available for sale and at December 31, 1997, unrealized gains and losses
were immaterial. Realized gains and losses during 1997 were also immaterial. For
the purpose of determining realized gains and losses, the costs of the
securities sold is based upon specific identification.

Property and Equipment

Property and equipment are stated at cost. Depreciation is provided using the
straight-line method over the estimated useful lives of the assets ranging from
three to five years. Leasehold improvements are amortized using the
straight-line method over the shorter of the estimated useful life of the asset
or the remaining lease term. Repair and maintenance costs are expensed as
incurred. Improvements and betterments are capitalized. Gains or losses on the
disposition of property and equipment are included in other income. Depreciation
expense was $605,000, $656,000 and $965,000 for the years ended December 31,
1997, 1996 and 1995, respectively.

Goodwill

Goodwill is amortized using the straight-line method over five to eight years
and is net of accumulated amortization of $325,000 and $221,000 as of December
31, 1997 and 1996, respectively. The related amortization expense was $104,000,
$48,000 and $48,000 for the years ended December 31, 1997, 1996, and 1995,
respectively.

The Company continually evaluates whether later events and circumstances have
occurred that indicate the remaining estimated useful life may warrant revision
or that the remaining goodwill balance may not be recoverable. If factors
indicate that goodwill should be evaluated for possible impairment, the Company
would use an estimate of the related undiscounted cash flows in measuring
whether goodwill should be written down to the fair value, in accordance with
SFAS No. 121 "Accounting for Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed of". Management believes that there has been no impairment
of long-lived assets as of December 31, 1997.


                                      F-8

Accrued Expenses

Included in accrued expenses at December 31, 1997 and 1996 is accrued payroll of
$538,000 and $235,000, respectively.

Software Development Costs

Research and development expenditures are charged to operations as incurred. In
1997, research and development expense was approximately $700,000. Research and
development expense was not material in 1996 and 1995. SFAS No. 86, "Accounting
for the Costs of Computer Software to be Sold, Leased or Otherwise Marketed,"
requires the capitalization of certain software development costs subsequent to
the establishment of technological feasibility. The Company has determined that
technological feasibility for its products is generally achieved upon completion
of a working model. Since software development costs have not been significant
after the completion of a working model, all such costs have been charged to
expense as incurred.

Advertising Costs

The Company expenses advertising costs as incurred. Advertising expense for the
years ended December 31, 1997, 1996 and 1995 was $310,000, $84,000 and $118,000,
respectively.

Income Taxes

Deferred tax assets and liabilities are recognized for the 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
expected to apply to taxable income in the years in which those temporary
differences are expected to be recovered or settled. 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. The Company was included in the
consolidated federal tax return of UM until February 1997 and files separate
state, local and foreign income tax returns. The accompanying financial
statements reflect income tax expense calculated on a separate-company basis for
all periods presented.

Supplemental Cash Flow Information

The Company paid approximately $819,000, $316,000 and $95,000 for income taxes
in the years ended December 31, 1997, 1996 and 1995, respectively, of which
$575,000 was paid to UM in 1997 in accordance with the tax sharing agreement. 
The Company was not required to make payments to UM for income taxes in 1996 or
1995 (see Note 7).

The following table displays the net non-cash assets that were consolidated as a
result of the Company's business acquisition (see Note 2):

          Non-cash asset (liabilities):
             Accounts receivable                                     $1,055,000
             Prepaid expenses and other                                  35,000
             Property and equipment                                     386,000
             Other assets                                                23,000
             In-process research and development                      7,883,000

             Accounts payable                                        (1,209,000)
             Accrued expenses                                          (450,000)
             Deferred revenues                                       (1,616,000)
                                                                    -----------
          Net cash paid for acquisition                              $8,655,000
                                                                    ===========


                                      F-9
<PAGE>

In 1995, the minority owner of Premier Research LLC (see Note 6) contributed
$50,000 of fixed assets.

Other Income

Other income consists primarily of earnings on short-term investments.

Concentration of Credit Risk and Significant Customers

Financial instruments that potentially subject the Company to concentration of
credit risk consist primarily of trade accounts receivable from companies
operating in the pharmaceutical industry. For the years ended December 31, 1996
and 1995 two and three clients accounted for 25% and 37% of the Company's net
revenues, respectively. No other single client accounted for greater than 10% of
net revenues during these periods. For the year ended December 31, 1997, no
single client accounted for greater than 10% of net revenues. Due to the
contract nature of the Company's business and the relative size of such
contracts in comparison to the Company, it is not unusual for a significant
customer in one year to be insignificant in the next year. The loss of any such
client could have a material adverse effect on the Company's operations. In
addition, the Company maintains reserves for potential credit losses and such
losses, in the aggregate, have not historically exceeded management
expectations.

Translation of Foreign Financial Statements

Assets and liabilities of the Company's UK subsidiary are translated at the
exchange rate as of the end of each reporting period. The income statement is
translated at the average exchange rate for the period. Cumulative adjustments
from translating the UK financial statements are immaterial.

Net Income (Loss) Per Common Share

In February 1997 the Financial Accounting Standards Board (FASB) issued SFAS No.
128 "Earnings per Share". This statement established new standards for computing
and presenting earnings per share and requires the restatement of prior year
amounts. The Company adopted SFAS No. 128 effective December 31, 1997.

Basic net income (loss) per share was computed by dividing net income (loss) by
the weighted average number of shares of common stock outstanding during the
year. Diluted net income (loss) per share was computed by dividing net income
(loss) by the weighted average number of shares of common stock outstanding
during the year, adjusted for the dilutive effect of common stock equivalents,
which consist of stock options, using the treasury stock method.

The table below sets forth the reconciliation of the numerators and denominators
of the basic and diluted net income (loss) per share computations. As required
by SFAS No. 128, all prior-period per share data has been restated to conform
with the provisions of the statement.

Options for 851,620 shares of common stock were outstanding at December 31, 1997
but were not included in the computation of diluted earnings per share because
their effect would be anti-dilutive. For the years ended December 31, 1996 and
1995, 8,804 and 473,215 common stock options, respectively, were outstanding but
were not included in the computation of diluted earnings per share because their
effect was not dilutive.

New Accounting Pronouncements

In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive Income".
This statement requires companies to classify items of other comprehensive
income by their nature in the financial statements and display the accumulated
balance of other comprehensive income separately from retained earnings and
additional paid-in-capital in the equity section of a statement of financial
position. SFAS No. 130 is effective for financial statements issued for fiscal
years beginning after December 15, 1997. Management believes that SFAS No. 130
will not have a material effect on the Company's financial statements.

In June 1997, the FASB issued SFAS No. 131, "Disclosure About Segments of an
Enterprise and Related Information". This statement establishes additional
standards for segment reporting in the financial statements and is effective for
fiscal years beginning after December 15, 1997. Management is currently
evaluating the impact SFAS No. 131 will have on its financial reporting.


2. ACQUISITION OF DLB SYSTEMS, INC.

Effective October 31, 1997, the Company acquired substantially all of the assets
of DLB Systems, Inc. ("DLB") for $6,500,000 in cash, its prior $1.0 million
investment and the assumption of certain liabilities. The acquisition was
accounted for under the purchase method of accounting, whereby the purchase
price was allocated to the assets acquired and the liabilities assumed, based on
their fair market values at the acquisition date. The excess of the purchase
price over the estimated fair market value of the net assets acquired was
assigned to identifiable intangibles. The Company assigned $7,883,000 to
in-process research and development and such amount was charged to operations in

5. LINE OF CREDIT:

The Company has a line of credit with a bank, through June 30, 1998, that
provides for borrowings up to $3 million at an interest rate of prime minus 35
basis points. The line of credit agreement includes certain covenants, the most
restrictive of which limit future indebtedness and require compliance with a
liabilities-to-tangible net worth ratio. To date, the Company has not borrowed
any amounts under its line of credit.

6. PREMIER RESEARCH LLC:

In September 1995, the Company and PREMIER, Inc. entered into the Agreement and
Plan of Organization of a limited liability company, Premier Research LLC
(Premier LLC). Under the terms of the agreement, PREMIER, Inc. contributed
$300,000 in cash, $50,000 in property, $30,000 in services and the business
operations of its Contract Research Organization Division for a 35% interest in
Premier LLC. The Company agreed to manage Premier LLC and to fund Premier LLC's
working capital needs for three years in exchange for a 65% interest in Premier
LLC. In accordance with the agreement, PREMIER, Inc.'s ownership interest in
Premier LLC automatically converted into 330,150 shares of common stock
concurrent with the Company's initial public offering.

7. INCOME TAXES:

The Company was included in the consolidated federal income tax returns of UM
until February 1997 under a tax-sharing agreement pursuant to which the Company
would pay to UM amounts equal to the taxes that the Company would have paid had
it filed separate federal income tax returns. In addition, taxes payable to UM
under the tax-sharing agreement for years prior to 1996 were forgiven by UM and,
accordingly, have been recorded as contributions from UM.

At December 31, 1997, the Company had a net operating loss carry-forward for
federal income tax purposes of approximately $879,000 which will expire in 2012,
a net operating loss carry-forward for state tax purposes of approximately $1.9
million which will expire in 2000 and a UK loss carry-forward of approximately
$1.3 million has no expiration date.

Management has determined that it is more likely than not that future taxable
income will be sufficient to realize all of the Company's deferred tax assets.
Approximately $11 million of future taxable income including approximately $1.3
million from the Company's UK subsidiary is needed for the Company to fully
realize the net deferred tax asset recorded at December 31, 1997.

8. RELATED PARTY TRANSACTIONS:

TRANSACTIONS WITH UM

UM provided various administrative services to the Company including accounting,
human resources and certain computer services prior to 1996. UM has historically
charged the Company for these services through corporate allocations based
primarily on actual costs incurred. These expenses were $160,000 for the year
ended December 31, 1995. In 1996, UM decentralized most of these functions, and
now provides primarily 401(k) administrative services. For the years ended
December 31, 1997 and 1996, UM's charges for these services were $24,000 and
$44,000, respectively.

The Company leases its primary operating facility from UM (see Note 10) and
participates in UM's 401(k) profit sharing plan. The Company was charged
$349,000, $382,000 and $488,000 for rent under the facility lease and $47,000,
$69,000 and $59,000 for profit sharing plan contributions for the years ended
December 31, 1997, 1996 and 1995, respectively. The Company believes that all
amounts charged by UM were reasonable.

In 1997, the Company paid UM $485,000 for 1996 income taxes payable and $90,000
for estimated 1997 income taxes due under the tax sharing agreement (see Note
7). The 1997 estimated payment will be refunded by UM in 1998.

TRANSACTIONS WITH THE COMPANY'S PRESIDENT

The Company's President, who is a stockholder, is a cardiologist who, in
addition to his role as President of the Company, provides medical services to
the Company as an independent contractor through his wholly-owned Professional
Corporation (see Note 10). Fees incurred under this consulting arrangement
approximated $144,000, $1,955,000 and $956,000 for the years ended December 31,
1997, 1996 and 1995, respectively. The Medical Director fees of $144,000 per
year are included in selling, general and administrative expenses and the
incremental fees, in 1996 and 1995, which primarily relate to medical
interpretations for diagnostic tests, are included in direct costs in the
accompanying statements of operations. In addition, at December 31, 1997 and
1996 amounts owed to the Company's President in connection with the consulting
agreement were $24,000 and $325,000, respectively, and are included in accounts
payable in the accompanying balance sheets.

The Company and the Company's President entered into new employment and
consulting agreements effective January 1, 1997 (see Note 10).

In January 1996, the President and UM entered into an agreement whereby the
President purchased 660,300 shares of the Company's Common Stock from UM for
$750,000. The President also has outstanding options to purchase 230,100 shares
of Common Stock (see Note 9).

9. STOCK OPTION PLANS:

In August 1993, the Company established a nonqualified stock option plan (the
"1993 Plan") authorizing the grant of options to acquire up to 1,100,500 shares
of the Company's common stock. The purpose of the 1993 Plan was to provide an
incentive for key individuals to advance the success of the Company. The options
cover the purchase of common stock of the Company at exercise prices initially
set at or above current fair value as determined by the Board of Directors.
Options granted under the 1993 Plan became fully vested 90 days after the
Company's initial public offering and expire five years from the initial public
offering date. No additional options may be granted under this plan.

In 1996, the Company adopted a new stock option plan (the "1996 Plan") that
authorizes the grant of both incentive and non-qualified options to acquire up
to 500,000 shares of the Company's common stock. The Company's Board of
Directors determines the exercise price of the options under the 1996 Plan. The
exercise price of incentive stock options may not be below fair value on the
grant date. Incentive stock options under the 1996 Plan expire ten years from
the grant date and are exercisable in accordance with vesting provisions set by
the Board.


Information with respect to outstanding options under the plans is as follows:

The Company accounts for its option grants under Accounting Principles Board
Opinion No. 25, "Accounting for Stock Issued to Employees", and the related
interpretations. In 1995, the FASB issued SFAS No. 123, " Accounting for
Stock-based Compensation". SFAS No. 123 established a fair value based method of
accounting for stock-based compensation plans. Had compensation cost for the
Company's stock option plans been determined based upon the fair value of the
options at the date of grant, as prescribed under SFAS No. 123, the Company's
net income (loss) and basic and diluted net income (loss) per share would have
been adjusted to the following pro forma amounts:

The weighted average fair value per share of the options granted during 1997,
1996 and 1995 was estimated as $5.40, $0.80 and $0.45, respectively. The fair
value of each option grant is estimated on the date of grant using the
Black-Scholes option-pricing model with the following weighted average
assumptions:


                                             1997         1996         1995

The effects of applying SFAS No. 123 in the pro forma disclosure are not
indicative of future amounts. SFAS No. 123 does not apply to options granted
prior to 1995, and additional option grants are anticipated.

10. COMMITMENTS AND CONTINGENCIES:

LEASES

The Company leases office space and equipment under operating leases, including
its primary operating facility, which it leases from UM under a lease agreement

AGREEMENTS WITH THE COMPANY'S PRESIDENT

The Company has entered into employment and consulting agreements with its
President (see Note 8). The employment agreement was executed in November 1996,
became effective January 1, 1997, and continues through December 31, 2001.
Either the Company or the President may terminate the agreement at any time,
with or without cause. However, if the Company terminates the agreement without
cause, the Company must continue to pay the President's salary for a one-year
period subsequent to the termination.

The consulting agreement was executed in October 1996, and relates to the
President's capacity as a medical doctor and cardiologist and, among other
things, requires the President to serve as Medical Director and/or principal
investigator for the Company in addition to providing medical interpretations of
diagnostic tests from time to time, as required. Compensation under the
consulting agreement is $144,000 per year. The consulting agreement commenced on
January 1, 1997 for a one-year period and will continue thereafter from year to
year unless terminated. The new consulting agreement replaced a prior agreement
whereby the President received additional compensation for medical
interpretations of diagnostic tests (see Note 8).


CONTINGENCIES

The Company believes it has adequate insurance coverage against possible
liabilities that may be incurred in connection with the conduct of its business
primarily as it relates to the testing of new drugs or medical devices. While
the Company believes it operates safely and prudently, in addition to managing
liability risks through contractual indemnification, the Company could be
materially and adversely affected if it were required to pay damages or incur
defense costs in connection with a claim that is beyond the scope of an
indemnity provision or insurance coverage, or if an indemnity is not upheld or
if the claim exceeds the insurance policy limits.

12. RECAPITALIZATION

On October 24, 1996, the Company's Board of Directors approved an amendment to
the Company's Certificate of Incorporation increasing the number of authorized
shares of common stock to 15,000,000 shares and authorizing 500,000 shares of
preferred stock. In addition, on November 26, 1996, the Company effected a
2,201-for-one split of its common stock. The increase in authorized shares and
