                                  THE COMPANY
   
  PRA International, Inc. (the "Company") is a leading contract research
organization ("CRO"), providing clinical research and development services on
an international basis to the pharmaceutical and biotechnology industries. The
Company believes that, based on net revenues, it is one of the 10 largest full-
service CROs in the world focused on managing human clinical trials. It also
believes that it is one of only several of these CROs capable of providing a
full range of clinical development services on an international basis. Since
January 1, 1996, the Company has conducted 288 programs for 68 sponsors,
including 22 of the 25 largest international pharmaceutical companies in the
world as measured by revenues and 11 of the 25 largest biotechnology companies
in the United States as measured by market capitalization. The Company
currently has preferred provider relationships with eight pharmaceutical and
biotechnology companies and is one of the three principal vendors of CRO
services at another seven pharmaceutical and biotechnology companies. The
Company's pro forma net revenues for the nine months ended September 30, 1997,
giving effect to the April 1, 1997 acquisition of International Medical
Technical Consultants, Inc. ("IMTCI") as if it had occurred on January 1, 1997,
were approximately $32.5 million. On September 30, 1997, the Company had 614
employees.     
 
  The Company offers a full range of services on a global basis that comprise
the clinical development process, from preparation of Investigational New Drug
("IND") applications and first-administration-in-man (Phase I) studies, through
large-scale clinical trials (Phases II--III) studies, to product marketing
registration in
 
                                       3
<PAGE>
 
the United States and Europe and post-marketing (Phase IV) studies. Specific
services performed by the Company include clinical program development, study
protocol design, project management, investigational site selection, regulatory
document management, study compliance monitoring, medical monitoring, data
collection and management, biostatistical analysis, medical writing and
regulatory document preparation and submissions. In addition to these standard
services, the Company offers specialized services that it believes enable it to
offer greater value to its clients. These services include single site proof of
concept studies, senior level strategic advisory services, investigational site
management services, a centralized Investigational Review Board ("IRB"), and
long term safety assessment and reporting services.
   
  The Company has provided clinical research and development services in North
America since 1982 and in Europe since 1992. The Company conducts its
operations through four trials management centers in the United States located
in Virginia, Kansas, New Jersey and California, one European trials management
center located in Mannheim, Germany, a 56-bed inpatient facility and a
dedicated outpatient clinic in the Kansas City area, seven investigational
sites located in the Kansas City area, Atlanta and Savannah as well as an
investigational affiliation in San Juan, Puerto Rico, and a data management
center in Swansea, Wales. The Company also plans to begin operations in the
London, England area in early 1998. In 1996, the Company derived 69% of its net
revenues from United States operations and 31% of its net revenues from
European operations. For the nine months ended September 30, 1997, the Company
derived 82% of its net revenues from United States operations, the increase
being largely due to two acquisitions in the United States, and 18% from
European operations.     
 
  The Company utilizes a decentralized operating model that empowers local
professionals at each of the Company's trials management centers to make key
operational decisions while supporting large-scale, global trials. By
strategically locating full service trials management centers near major
sponsors and permitting each center to be responsive to clients, the Company
believes it enhances service quality and client relationships. All of the
Company's trials management centers are integrated through shared business
practices, standard operating procedures and common information systems. As a
result, each trials management center can deliver services reflecting the
international expertise, support and resources of the entire Company.
   
  The Company believes that its depth of clinical management is significant and
that, drawing on these resources, it has developed significant expertise in
clinical development as well as in a number of therapeutic areas. The Company's
staff of approximately 614 employees includes an extensive roster of senior
level scientific, regulatory and clinical experts providing direction and
oversight to clinical development projects and day-to-day operations, including
approximately 16 who are M.D.s, 35 who have Ph.D.s, 3 who are Pharm.D.s, and 74
others who have master's level degrees. In addition, the Company has retained a
number of distinguished industry advisors and consultants who assist as needed
in providing input into drug development and regulatory approval strategies for
clients and in developing recommendations concerning potential improvements to
the Company's clinical development procedures. The Company believes that it has
established significant expertise in a number of therapeutic areas, namely
oncology, central nervous system disorders, cardiovascular diseases and allergy
and respiratory conditions.     
   
  The pharmaceutical and biotechnology industries spent an estimated $35.0
billion in 1996 on research and development, of which the Company estimates
$18.0 billion was spent on the types of services offered by the Company. Of
this amount, approximately $6.0 billion was outsourced to clinical trials and
site management businesses. The Company believes that the CRO industry will
continue to grow due to (i) cost containment pressures causing pharmaceutical
and biotechnology companies to shift fixed costs to variable costs by
outsourcing drug development services, (ii) the globalization of the drug
development process, (iii) the increasing complexity of drug regulations and
clinical trials, and (iv) continued growth of the biotechnology industry, which
increasingly makes greater use of CROs. In addition, the Company believes that
many pharmaceutical and biotechnology companies are designating a limited
number of "preferred provider" CROs to assist in larger projects, further
fueling the growth of large full service CROs capable of conducting trials on
an international basis and further emphasizing therapeutic expertise and value-
added services. To be a "preferred provider" in     
 
                                       4
<PAGE>
 
   
the CRO business means to be among the pre-qualified CRO service providers a
pharmaceutical or biotechnology company ordinarily utilizes for clinical trial
services, pursuant to previously established forms of agreements and documents.
    
  The Company's strategy is to (i) continue to focus on providing clinical
trials management services on an international basis, offering a full range of
services at each of its trials management centers, (ii) expand and enhance
areas of therapeutic expertise, (iii) continue to provide value-added services
that enhance the Company's core service offerings, (iv) continue to invest in
and enhance the Company's information technology, and (v) continue to grow
internally and through selected acquisitions that expand the Company's
geographic presence, enlarge the scope of its therapeutic expertise, or enable
it to provide additional value-added services.

                                  THE COMPANY
   
  The Company was incorporated in 1996 when it was formed to become the
holding company for Pharmaceutical Research Associates, Inc., a Virginia
corporation ("Associates"), which was incorporated in 1982. The Company's
European operations are conducted principally through Associates' wholly-owned
subsidiary, Pharmaceutical Research Associates GmbH ("PRA GmbH"), which was
formed in Germany in 1992. In the last quarter of 1996, Associates formed a
wholly-owned subsidiary, Pharm. Research Associates (UK) Limited ("PRA
Limited"), a United Kingdom private company through which the Company operates
its data management facility in Swansea, Wales.     
   
  On April 1, 1997, the Company acquired International Medical Technical
Consultants, Inc., a Kansas corporation ("IMTCI"), which in turn acquired The
Crucible Group, Inc., a Georgia corporation ("Crucible"), on May 19, 1997. In
October 1997, IMTCI formed a wholly-owned subsidiary, IMTCI (UK) Limited, a
United Kingdom private company ("IMTCI Limited"), which currently has no
assets or operations.     
   
  In October 1996, the Company completed a recapitalization and
reorganization. First, the Company became the holding company of Associates,
pursuant to an agreement and plan of share exchange between the Company and
Associates. Under the agreement and plan of share exchange, all outstanding
shares and all options and warrants to purchase shares of each class of common
and preferred stock of Associates were acquired by the Company in exchange for
an identical number of outstanding shares and options and warrants to purchase
shares of Common Stock. The Company then sold, for an aggregate purchase price
of approximately $19.1 million, 1,631,548 shares of its Series A Preferred
Stock to certain affiliates of The Carlyle Group, along with a related warrant
agreement providing for the issuance of warrants to purchase an identical
number of shares of Common Stock upon the occurrence of certain circumstances.
In November 1996, Virginia Capital, L.P. purchased 26,534 shares of Series A
Preferred Stock and a related warrant agreement for an aggregate purchase
price of approximately $310,000. The Company used approximately $9.2 million
of the proceeds from the sale of the Series A Preferred Stock to purchase
certain shares of, or options for, Common Stock.     
 
  The Company's principal executive offices are located at American Center,
8300 Boone Boulevard, Suite 310, Vienna, Virginia 22182, and its telephone
number is (703) 748-0760.

                                 RISK FACTORS
 
  In addition to the other information contained in this Prospectus, the
following risk factors should be considered carefully before making an
investment in the Common Stock offered hereby.
 
LOSS OR DELAY OF CONTRACTS; PRICING UNDER CONTRACTS
 
  Most of the Company's contracts are terminable without cause upon 30 to 60
days' notice by the client. Clients terminate or delay contracts for various
reasons including, among others, the failure of the product 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;
the inadequate performance of the CRO, including the quality of data provided
and the CRO's failure to meet agreed upon schedules; clients' decisions to
downsize their product development portfolios; insufficient patient enrollment
or investigator recruitment; and production problems resulting in shortages of
required clinical supplies. Quality control is critical to CROs since not only
can contracts be terminated by sponsors as a result of poor CRO performance,
but these terminations also may affect a CRO's ability to obtain future
contracts from the sponsor involved and, possibly, others among the relatively
small number of companies that sponsor trials.
 
  The Company does not believe that its backlog as of any date is necessarily
a meaningful predictor of future results. The loss or delay of a large program
or contract or the loss or delay of multiple smaller contracts could have a
material adverse effect on the Company, because such terminations could lower
the level of staff utilization, which would adversely affect profitability. A
majority of the Company's contracts for the provision of its services are
fixed price, with limited variable components, although a significant portion
of these contracts are modified in scope during the course of these contracts,
which permits price adjustments. In the case of fixed price contracts, the
Company bears the risk of cost overruns. Underpricing of contracts or
significant cost overruns could have a material adverse effect on the Company.
See "Management's Discussion and Analysis of Financial Condition and Results
of Operations," "Business--Contractual Arrangements" and "Business--Backlog."
 
MANAGEMENT OF GROWTH
 
  The Company has experienced rapid growth over the past five years throughout
its operations. The Company believes that sustained growth places a strain on
operational, human and financial resources. To manage its growth, the Company
must continue to improve its operating and administrative systems and to
attract and retain qualified management, professional, scientific and
technical operating personnel at reasonable cost that does not adversely
affect margins. The Company believes that maintaining and enhancing both its
systems and personnel at reasonable cost are instrumental to success in the
CRO industry. The Company continually upgrades its systems and has made a
significant investment in this area in the past two years. However, there can
be no assurance that such measures will prove adequate, that these upgrades
will be effectively or efficiently implemented, or that it will be able to
enhance its current technology or obtain new technology that will enable its
systems to keep pace with developments and the sophisticated needs of its
clients. The nature and magnitude of the Company's growth introduce risks
associated with quality control and client dissatisfaction due to delays in
performance or other problems. Foreign operations also involve the additional
risks of assimilating differences in foreign business practices, hiring and
retaining qualified personnel and overcoming language barriers. Failure to
manage growth effectively could have an adverse effect on the Company. See
"Business--General," "Business--Employees" and "Management."
 
VARIATION IN QUARTERLY OPERATING RESULTS
 
  The Company's quarterly operating results have been and will continue to be
subject to variation, depending on factors such as the commencement,
completion or cancellation of significant contracts, the timing of
acquisitions, the mix of contracted services, foreign exchange rate
fluctuations, the timing of start-up expenses for new offices and services,
the growing of the site management organization and the costs associated with
integrating acquisitions. The Company has experienced, and expects to continue
experiencing in the future, some
 
                                       8
<PAGE>
 
seasonal variations in its revenues, in part due to seasonal variations in
certain diseases or conditions that are the subject of clinical trials. The
Company believes that quarterly comparisons of its financial results should
not be relied upon as an indication of future performance. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Results of Operations and Quarterly Results."
 
INTEGRATION OF ACQUISITIONS
   
  The Company has made two acquisitions of various sizes since March 31, 1997.
See "The Company." There can be no assurance that the Company's management
will be able (i) to integrate successfully the operations of these acquired
companies into its business, (ii) to sustain, on a combined basis, the
operating performance that each of the Company and the acquired companies had
on a standalone basis or (iii) to effectively implement the Company's
operating or growth strategies. See "Business--General" and "Management." The
Company reviews acquisition candidates in the ordinary course of its business.
Acquisitions involve numerous risks, including the expenses incurred in
connection with the acquisition, difficulties in assimilating operations, the
diversion of management's attention from other business concerns, and the
potential loss of key employees of the acquired company. Acquisitions of
foreign companies involve the additional risks of assimilating differences in
foreign business practices, hiring and retaining qualified personnel, and
overcoming language barriers. There can be no assurance that any future
acquisitions will be successfully integrated into the Company's operations.
See "Use of Proceeds" and "Business--Company Strategy.'"     
 
SITE MANAGEMENT BUSINESS
   
  With the acquisitions of IMTCI and Crucible, the Company acquired
investigational site management operations. The Company expects that through
its site management organization ("SMO") business, which consists of the
Company providing the necessary patient recruitment, scheduling, management,
training and other support functions for the establishment and support of
clinical investigational sites, the Company will provide site management
services to sponsors directly and to both the Company's clinical trials
management business and other CROs. The Company's trials management business
consists of its performance of the following functions on an as-needed basis:
designing study protocols, selecting and recruiting investigators to conduct
studies, managing the study process, collecting and analyzing the data
obtained from studies and compiling the results for regulatory submission. See
"Business--Additional Value-Added Services." Some CROs may be reluctant to use
the site management services of a competitor and this could have an adverse
effect on the Company's site management business. See "Business--Competition."
In addition, the Company plans to continue expanding its investigational site
management business in order to achieve what it believes to be the optimal
scale for long term success in this area. If fully implemented, this would
require a substantial investment and it involves a strategy that is largely
unproven. The Company's efforts to expand its SMO business are at an early
pilot stage and will require significant investment, and there can be no
assurance that the Company will be able to achieve this expansion in a
profitable manner or be able to expand to a scale optimal for SMO operations.
There can be no assurance that the Company will be successful in these
efforts. In addition, the site management business may not grow at the same
rate as the trials management business, if either of these businesses should
grow at all, and the margins for the SMO business may be less than those of
the CRO business. See "Business--Company Strategy."     
 
DEPENDENCE ON USE OF OUTSOURCING; CLIENT CONCENTRATION
 
  The Company's net revenues are highly dependent on research and development
expenditures by companies in the pharmaceutical and biotechnology industries.
Among other risks, this makes the Company dependent upon the industries' use
of outsourcing and, due to the nature of the industries, subject to
concentration of resources. To date, the Company believes that it has
benefited from the growing tendency of pharmaceutical and biotechnology
companies to outsource their product development programs to independent CROs.
Any reduction in the outsourcing of research and development expenditures in
these industries could have a material adverse effect on the Company.
 
                                       9
<PAGE>
 
   
  The Company has in the past derived, and is likely to continue to derive, a
significant portion of its net revenues from a relatively limited number of
major programs or clients. Further concentration would be experienced if, as
the Company anticipates, sponsors rely increasingly on preferred provider
relationships (as described in "Business--Customers and Marketing"). To the
extent that it is able to do so, the Company intends to enter into these
arrangements. This could have the effect of increasing the Company's reliance
on a smaller number of sponsors. In 1995, two clients accounted for
approximately 13% and 11% of the Company's net revenues. During 1996, two
different clients accounted for approximately 13%, and 11% of the Company's
net revenues. For the nine-month period ended September 30, 1997, two
different clients accounted for approximately 15% and 10% of the Company's net
revenues. The loss of any such client could have a material adverse effect on
the Company. Customer concentration in the CRO industry is not uncommon and
the Company is likely to continue to experience such concentration in the
future, particularly if preferred provider relationships become a more
dominant aspect of the CRO industry. See "Business--Industry Overview,"
"Business--Company Strategy," and "Business--Customers and Marketing."     
 
COMPETITION; INDUSTRY CONSOLIDATION
 
  The Company competes against other CROs, in-house development at large
pharmaceutical companies, and, to a lesser extent, universities and teaching
hospitals. Some of these competitors have greater capital and other resources
than the Company. As a result of competitive pressures and the potential for
economies of scale, the industry is consolidating rapidly. This trend, as well
as a trend by pharmaceutical companies and other clients to limit outsourcing
to fewer organizations, in some cases through preferred provider
relationships, is likely to produce increased worldwide competition among the
larger CROs for clients and acquisition candidates. There are few barriers to
entry for small, limited-service entities entering the CRO industry, and these
entities also may compete with established CROs for clients. The Company
believes that major pharmaceutical, biotechnology and medical device companies
have been developing preferred provider relationships with full-service CROs,
effectively excluding other CROs from the bidding process. The Company's
preferred provider relationships are not contractual and are subject to change
at any time. The Company may find reduced access to certain potential clients
due to preferred provider arrangements with other competitors. In addition,
the CRO industry has attracted the attention of the investment community, and
increased potential financial resources are likely to lead to increased
competition among CROs. Increased competition may lead to price and other
forms of competition that could adversely affect the Company. See "Business--
Industry Overview," "Business--Customers and Marketing" and "Business--
Competition."
 
DEPENDENCE ON KEY PERSONNEL
   
  The Company relies on a number of key executives including: Earle Martin,
its Chairman, President and Chief Executive Officer; Joachim Vollmar,
Executive Vice President, European Operations; James C. Powers, Executive Vice
President, Business Development; Patrick K. Donnelly, Executive Vice President
and Chief Financial Officer; and Dr. Robert Dockhorn, Executive Vice
President, IMTCI. The Company has employment agreements with each of the
foregoing individuals. The loss of the services of any of the Company's key
executives could have a material adverse effect on the Company. There can be
no assurance the Company will be able to continue to attract and retain
qualified personnel. See "Business--Employees" and "Management."     
 
POTENTIAL LIABILITY
 
  Clinical research services involve the testing of new drugs and devices on
human volunteers pursuant to a study protocol that has been approved by an
impartial review board with medical and non-medical members. This testing
creates risks of liability for personal injury, sickness or death of patients
resulting from their participation in the study. These risks include, among
other things, unforeseen adverse side effects, improper application of a new
drug or device and the professional malpractice of medical care providers.
Many volunteer patients already are seriously ill and are at heightened risk
of future illness or death. In connection with its provision of contract
research services, the Company contracts with physicians to serve as
investigators in conducting clinical trials on human volunteers. Although the
Company does not believe it is legally accountable for the medical care
rendered by third party investigators, it is possible that the Company could
be held liable
 
                                      10
<PAGE>
 
   
for the claims and expenses arising from any professional malpractice of the
investigators with whom it contracts in the event of personal injury to or
death of persons participating in clinical trials. The Company also could be
held liable for errors or omissions in connection with the services it
performs, including in connection with providing site management organization
services. The Company also could be liable for the general risks associated
with a Phase I facility including, but not limited to, adverse reactions to
the administration of drugs. The Company believes that its liability risks are
reduced by (i) contractual indemnification provisions with clients and
investigators, (ii) insurance maintained by clients and investigators and by
the Company, (iii) various regulatory requirements, including the use of IRBs
and (iv) the procurement of each volunteer's informed consent to participate
in the study. Contractual indemnifications generally do not, however, protect
the Company against certain of its own actions, such as negligence. The
contractual agreements are separately negotiated with clients, and the terms
and scope of indemnification vary from client to client and from trial to
trial. The financial performance of these indemnities is not secured, and the
Company bears the risk that the indemnifying party may not have the financial
ability to fulfill its indemnification obligations. The Company maintains
professional liability insurance that covers worldwide territories in which
the Company currently does business and includes drug safety issues as well as
data processing and management errors and omissions. There can be no assurance
that the Company will be able to maintain such insurance coverage on terms
acceptable to the Company. The Company could be materially and adversely
affected if (i) it were required to pay damages or bear the costs of defending
any claim outside the scope of, or in excess of, a contractual indemnification
provision or that is beyond the level of insurance coverage that is in effect
(if any), or (ii) an indemnifying party does not fulfill its indemnification
obligations. The Company believes that the amount of its liability insurance
coverage is adequate. See "Business--Potential Liability and Insurance."     
 
DEPENDENCE ON GOVERNMENT REGULATIONS; POSSIBLE NONCOMPLIANCE
 
  Regulations regarding the development and approval of drugs and biological
products have become increasingly stringent in both the United States and
Europe, resulting in a need for more complex and often larger clinical
studies. The Company believes that these trends have created an increased
demand for CRO services from which the Company's business benefits. Human
pharmaceutical products and biological products are subject to rigorous
regulation by the United States government, principally the Food and Drug
Administration ("FDA"), and by foreign governments, principally the European
Medicines Evaluation Agency ("EMEA"), if products are tested or marketed
abroad. Because the Company offers services relating to the conduct of
clinical trials and the preparation of 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. A relaxation of the
scope of regulatory requirements, such as the introduction of simplified
marketing applications for pharmaceuticals and biologics, could decrease the
business opportunities available to the Company. In addition, the Company's
failure to comply with applicable regulations relating to the conduct of
clinical trials or the preparation of marketing applications could lead to a
variety of sanctions. Such sanctions could have a material adverse effect on
the Company. See "Business--Government Regulation."
   
GOODWILL     
   
  In connection with recent acquisitions, the Company has recorded significant
goodwill. See "The Company." The Company reviews the amount of its goodwill
whenever events or changes in circumstances indicate that the carrying amount
of the goodwill may not be fully recoverable. To determine recoverability, the
Company evaluates the probability that future undiscounted cash flows, without
interest charges, will be less than the carrying amount of the assets. There
is a possibility that the carrying amount of the goodwill could be impaired if
the acquisitions are not successful, in which case an additional charge to
earnings would become necessary.     
 
UNCERTAINTY IN HEALTH CARE INDUSTRY AND POTENTIAL HEALTH CARE REFORM
 
  The United States federal government, many state governments and a number of
foreign governments have undertaken efforts to control growing health care
costs through legislation, regulation and voluntary agreements with medical
care providers and pharmaceutical, biotechnology and medical device companies.
In recent years,
 
                                      11
<PAGE>
 
several comprehensive health care reform proposals have been introduced in the
United States Congress. In Germany, there has been increased governmental
interest and involvement in the health care sectors. The objective of the
increased governmental initiatives has been generally to expand health care
coverage and to reduce the growth of total health care expenditures. While
none of the comprehensive reform proposals have been adopted, health care
reform may again be addressed by the U.S. federal government or by other
domestic and foreign authorities. Implementation of comprehensive or
incremental government health care reform may adversely affect research and
development expenditures by pharmaceutical, biotechnology and medical device
companies, which could decrease the business opportunities available to the
Company. The Company is unable to predict the likelihood of such legislation
being enacted into law or the effects such legislation or cost containment
pressures would have on the Company. See "Business--Industry Overview" and
"Business--Government Regulation."
 
RISK OF HAZARDOUS MATERIAL CONTAMINATION
 
  The Company's clinical and site management activities have involved, and may
continue to involve, the controlled use of hazardous materials. Although the
Company believes that its safety procedures for handling the disposal of such
materials comply with the standards prescribed by state and federal laws and
regulations, the risk of accidental contamination or injury from these
materials cannot be completely eliminated. In the event of such an accident,
the Company could be held liable for damages which, to the extent not covered
by existing insurance or indemnification, could have a material adverse effect
on the Company.
 
NO PRIOR MARKET; POSSIBLE VOLATILITY OF STOCK PRICE
 
  Prior to the Offering, there has been no public market for the Company's
Common Stock, and there can be no assurance that an active public market will
develop or be sustained after the Offering. The initial public offering price
will be determined through negotiations between the Company and the
Underwriters and may not be indicative of future market prices. See
"Underwriting" for a discussion of the factors to be considered in determining
the initial public offering price. The market price of the Company's Common
Stock could be subject to wide fluctuations in response to variations in
operating results from quarter to quarter, changes in earnings estimates by
analysts, worldwide market changes and competition in the CRO industry and
general economic conditions. Furthermore, the stock market has experienced,
and may further experience in the future, significant price and volume
fluctuations unrelated to the operating performance of particular companies.
These market fluctuations may have a material adverse effect on the market
price of the Company's Common Stock.
 
THE EFFECT OF CERTAIN CHARTER PROVISIONS; POTENTIAL PREFERRED STOCK ISSUANCE
 
  Pursuant to the Company's Restated Certificate of Incorporation, to be
effective upon the closing of the Offering (the "Restated Certificate of
Incorporation"), special meetings of the stockholders may be called only by
the Chairman of the Board, the President or a majority of the Board of
Directors of the Company. The Restated Certificate of Incorporation also
provides for staggered three year terms for members of the Board of Directors
and the Company's Amended and Restated By-Laws (the "By-Laws"), to be
effective upon the closing of the Offering, contain specific procedures for
director nominations by stockholders and submission of other proposals for
consideration at stockholder meetings. In addition, the Company has 5,000,000
authorized shares of preferred stock of the Company (the "Preferred Stock"),
none of which will be outstanding upon completion of the Offering. Pursuant to
the Company's Restated Certificate of Incorporation, the Board of Directors
has the authority to issue Preferred Stock in one or more series, and, to the
fullest extent permitted by law, to fix the rights, preferences, privileges
and restrictions, including dividend, conversion, voting, redemption
(including sinking fund provisions) and other rights, liquidation preferences
and the number of shares constituting any series and the designation of such
series, without any further vote or action by the stockholders of the Company.
The Company has no present plans to issue any shares of Preferred Stock. The
amendment of any of the foregoing provisions of the Restated Certificate of
Incorporation requires an affirmative super-majority (two-thirds) stockholder
vote. Furthermore, the Company is subject to the provisions of Section 203 of
the General Corporation Law of Delaware. In general, Section 203 prohibits a
publicly-held Delaware corporation
 
                                      12
<PAGE>
 
from engaging in a "business combination" with an "interested stockholder" for
a period of three years after the date of the transaction in which the person
became an interested stockholder, unless the business combination is approved
in a prescribed manner. A "business combination" includes mergers, asset sales
and other transactions resulting in a financial benefit to the interested
stockholder. Subject to certain exceptions, an "interested stockholder" is a
person that, together with affiliates and associates, owns, or within three
years did own, 15% or more of the corporation's voting stock. These charter
and statutory provisions may have the effect of deterring hostile takeovers or
delaying or preventing changes in control or management of the Company,
including transactions in which stockholders might otherwise receive a premium
for their shares over then-current market prices, and also could limit the
price that investors might be willing to pay in the future for shares of
Common Stock. See "Description of Capital Stock."
 
DILUTION TO NEW INVESTORS
   
  Purchasers of Common Stock in the Offering will experience immediate and
substantial dilution in the net pro forma tangible book value per share of the
Common Stock of $7.51 per share. See "Dilution."     
 
CONTROL BY CURRENT STOCKHOLDERS
   
  Following the Offering, assuming no exercise of the Underwriter's over-
allotment option, the Company's current stockholders will beneficially own
approximately 65% of the outstanding shares of Common Stock (or approximately
72% of the shares of Common Stock on a fully diluted basis, after giving
effect to the exercise of all outstanding options and other rights to acquire
Common Stock). In addition, a single stockholder will beneficially own
approximately 41% of the outstanding shares of Common Stock (or 33% of the
shares of Common Stock on a fully diluted basis). As a result, such current
stockholders will have the ability to control the election of the Company's
directors and the outcome of corporate actions requiring stockholder approval.
This concentration of ownership could have the effect of discouraging
potential take-over attempts and may make more difficult attempts by
stockholders to change the management of the Company. See "Principal
Stockholders."     
 
ABSENCE OF DIVIDENDS
   
  The Company has no present plans to pay cash dividends to its stockholders
and, for the foreseeable future, intends to retain all of its earnings for use
in its business. The declaration of any future dividends by the Company is
within the discretion of its Board of Directors and will be dependent on the
earnings, financial condition and capital requirements of the Company, as well
as any other factors deemed relevant by its Board of Directors. In addition,
the Company's current credit facility with First Union National Bank (the
"Credit Facility") contains covenants prohibiting the payment of cash
dividends without the consent of the lender. See "Dividend Policy."     
 
BROAD DISCRETION IN ALLOCATION OF PROCEEDS
 
  The Company has not designated any specific use for the majority of the net
proceeds of the Offering. Rather, the Company intends to use a majority of the
net proceeds for general corporate purposes, which may include acquisitions.
Accordingly, management will have significant flexibility in applying the net
proceeds of the Offering. See "Use of Proceeds."
 
SHARES ELIGIBLE FOR SALE
 
  Upon completion of the Offering, of the 25,000,000 authorized shares of
Common Stock, 9,726,588 shares will be issued and outstanding or reserved for
issuance pursuant to the exercise of outstanding stock options and one
outstanding warrant. Upon completion of the Offering, the Company will have
7,753,053 shares of Common Stock outstanding. The 2,750,000 shares offered
hereby will be freely tradeable without restriction under the Securities Act
of 1933, as amended (the "Securities Act"), except for any such shares held by
"affiliates" of the Company within the meaning of the Securities Act, which
will be subject to the resale limitations of Rule 144
 
                                      13
<PAGE>
 
promulgated under the Securities Act ("Rule 144"). The Company believes that
the remaining outstanding shares, and the 1,414,084 shares issuable upon
exercise of outstanding options and one outstanding warrant, may be sold
pursuant to Rule 144 or Rule 701 under the Securities Act in compliance with
the limitations thereof beginning 90 days after the Offering. In accordance
with the terms of the "lock-up" agreements entered into with the Company, the
Company's directors, executive officers and certain of its stockholders have
agreed not to sell the shares owned by each of them without the prior written
consent of Smith Barney Inc. for a period of 180 days following the first
offer of shares of Common Stock pursuant to this Prospectus, although in some
cases, certain transfers to affiliated parties are permitted. See "Shares
Eligible for Future Sale." Certain stockholders of the Company have the right
to demand that the Company register for resale, on not more than four
occasions, an aggregate of 4,198,428 shares of Common Stock held by them or
issuable upon the exercise of one outstanding warrant. Such stockholders and
certain other stockholders of the Company have the right with respect to an
aggregate of 4,380,616 shares of Common Stock held by them or issuable upon
the exercise of one outstanding warrant to have such shares included in any
subsequent registration by the Company. See "Description of Capital Stock--
Registration Rights." Sales of a substantial number of shares of Common Stock
in the public market, or the possibility of such sales occurring, could
adversely affect the market price of the Common Stock.
 
UNCERTAINTY OF FORWARD LOOKING STATEMENTS
 
  All statements contained herein that are not descriptions of past or present
facts are based on current expectations. These statements are forward-looking
in nature and involve a number of risks and uncertainties. Actual results may
vary materially for the specific reasons discussed elsewhere in this Risk
Factors section. The Company believes that the risks and uncertainties in the
forward-looking statements are particularly significant because the Company's
strategy and projections assume, among other things, that the Company will be
able to maintain quality control, manage its growth and integrate future
acquisitions into its operations. The Company cautions potential investors not
to place undue reliance on any such forward-looking statements.

                                USE OF PROCEEDS
   
  The net proceeds to the Company from the sale of the 2,750,000 shares of
Common Stock offered by the Company hereby, after deducting underwriting
discounts and estimated offering expenses, are estimated to be $27.1 million
($31.4 million if the Underwriters' over-allotment option is exercised in
full), assuming an initial public offering price of $11.00 per share, which is
the mid-point of the range of the estimated public offering price. Of this
amount, approximately $4.0 million will be used for capital expenditures and
approximately $10.9 million will be used for the repayment of certain
indebtedness anticipated to be outstanding at the time of the Offering. This
amount includes $10.1 million outstanding as of September 30, 1997 (including
approximately $200,000 in unamortized debt discount) and an estimated $0.8
million of additional borrowings after September 30, 1997. The balance of such
net proceeds of approximately $12.2 million will be retained for working
capital and other general corporate purposes including possible future
acquisitions and geographic expansion. Pending such uses, the Company intends
to invest the net proceeds in short-term, investment-grade interest-bearing
instruments.     
   
  The Company intends to repay from the net proceeds of the Offering a
subordinated secured venture capital loan of approximately $2.0 million, which
was made to Associates in August 1995 by Sirrom Capital Corporation, whose
successor is Sirrom Investments, Inc. This loan bears interest at the rate of
13.5% per annum and matures on August 10, 2000. The Company also intends to
repay from the net Offering proceeds all or a portion of (i) the $4.3 million
and $1.0 million subordinated notes payable by the Company to the former
stockholders of IMTCI in connection with the IMTCI stock acquisition, which
notes bear interest at the rate of 8.33% per annum and mature on April 1, 2001
and April 1, 2000, respectively, and (ii) approximately $3.6 million
(estimated as of the closing of the Offering) outstanding under the Company's
current $7.5 million secured revolving credit facility with First Union
National Bank. The outstanding balance of that facility matures on June 30,
1999 and bears interest at LIBOR plus 2%. See Note 6 to Notes to Consolidated
Financial Statements of the Company and "Management's Discussion and Analysis
of Financial Condition and Results of Operations--Liquidity."     
 
  The Company's management will have broad discretion to allocate the net
proceeds of the Offering to uses it believes are appropriate. There can be no
assurance that the net proceeds of the Offering can or will be invested in a
manner that yields a positive return.
 
 
                                DIVIDEND POLICY
 
  The Company does not anticipate paying any dividends on its Common Stock for
the foreseeable future, and intends to retain all available funds for use in
the operation and expansion of its business. Pursuant to the terms of the
Series A Preferred Stock and related contractual arrangements, all accrued
cumulative dividends on the Series A Preferred Stock will be forfeited upon
the automatic conversion of the Series A Preferred Stock at the closing of the
Offering. In addition, the Company's current credit facility with First Union
National Bank contains covenants prohibiting the payment of cash dividends
without the consent of the lender. Any determination to declare or pay cash
dividends in the future will be at the discretion of the Company's Board of
Directors and will depend on, among other things, the Company's financial
condition and results of operations, contractual restrictions now or hereafter
imposed by lenders and others, requirements of applicable law and other
considerations deemed relevant by the Company's Board of Directors. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources" and "Description of Capital
Stock."

                                CAPITALIZATION
   
  The following table sets forth the capitalization of the Company as of
September 30, 1997, (i) on an actual basis and (ii) on an as adjusted basis,
adjusted to give effect to the conversion of all outstanding shares of Series
A Preferred Stock to Common Stock and to give effect to the sale of 2,750,000
shares of Common Stock offered by the Company hereby at an assumed initial
public offering price of $11.00 per share, which is the midpoint of the range
of the estimated public offering price (after deducting underwriting discounts
and estimated offering expenses), and the application of the estimated net
proceeds therefrom to repay certain indebtedness of the Company, which on
September 30, 1997 was approximately $10.1 million (including approximately
$200,000 in unamortized debt discount) (see "Use of Proceeds"). This table

Pro Forma Condensed Consolidated Financial Statements and the related Notes

                                    DILUTION
   
  As of September 30, 1997, the Company had a deficit in pro forma net tangible
book value of approximately $50,511, or $0.01 per share. Pro forma net tangible
book value per share is equal to the Company's total tangible assets less total
liabilities, divided by the total number of shares of Common Stock outstanding
after giving effect to the conversion of the Series A Preferred Stock. After
giving effect to the sale by the Company of the 2,750,000 shares of Common
Stock offered hereby at an assumed initial public offering price of $11.00 per
share, and after deducting the estimated underwriting discount and estimated
offering expenses, the pro forma net tangible book value of the Company as of
September 30, 1997, would have been $27.1 million or $3.49 per share of Common
Stock. This represents an immediate increase in pro forma net tangible book
value of $3.50 per share to existing stockholders and an immediate dilution of
$7.51 per share to new investors. The following table illustrates this per
share dilution:

allotment option. As of September 30, 1997, there were 1,951,025 shares of
Common Stock reserved for issuance upon exercise of outstanding options and
warrants at a weighted average exercise price of $4.29 per share. To the extent
that these options or warrants are exercised, there will be further dilution to
new investors. See "Management--Stock Incentive Plans."

                     SELECTED CONSOLIDATED FINANCIAL DATA
   
  The following table sets forth selected consolidated financial data of the
Company. The selected consolidated financial data as of December 31, 1996 and
for the year then ended, have been derived from consolidated financial
statements audited by Arthur Andersen LLP, independent accountants. The
selected consolidated financial data as of December 31, 1993, 1994 and 1995
and the years then ended have been derived from financial statements audited
by Ernst & Young LLP, independent auditors. The selected consolidated
financial data as of December 31, 1992 and September 30, 1996 and 1997, and
for the year and the nine-month periods then ended, respectively, have been
derived from unaudited consolidated financial statements of the Company and
have been prepared on the same basis as the audited consolidated financial
statements. In the opinion of management, the unaudited consolidated financial
statements reflect all adjustments that management considers necessary for a
fair and consistent presentation of the financial position and results of
operations for those periods. The results of operations for the nine-month
period ended September 30, 1997, are not necessarily indicative of the results
of the Company's operations that may be expected for the fiscal year ending
December 31, 1997 or for any future annual or interim period. The following
selected consolidated financial data are qualified by reference to, and should
be read in conjunction with, "Management's Discussion and Analysis of
Financial Condition and Results of Operations," the consolidated financial
statements of the Company, and the Notes thereto included elsewhere in this
Prospectus.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion and analysis should be read in conjunction with the
Financial Statements and related Notes contained elsewhere in this Prospectus,
as well as the matters discussed in "Risk Factors." Except for the historical
information contained herein, the discussion in this Prospectus contains
certain forward-looking statements that involve risks and uncertainties.
 
OVERVIEW
 
  The Company provides a broad range of clinical research and development
services on a contract basis to companies in the pharmaceutical and
biotechnology industries. Revenues are derived from services provided by the
Company, including Phase I-IV clinical trial design, management and
implementation, clinical data management and biostatistical analysis, medical
writing and regulatory services.
   
  The Company has broadened its range of services in the United States and in
Europe through acquisitions and internal growth. In the past year, the Company
opened or acquired trials management operations in New Jersey, California and
Kansas, investigational sites in eight locations and a data management center
in Swansea, Wales. In April 1997, the Company acquired the capital stock of
IMTCI, a CRO with a trials management center and clinical investigational
sites in the Kansas City area. Of the aggregate purchase price of
approximately $15.3 million paid to IMTCI's stockholders, $8.0 million was
paid in the form of cash, $5.3 million was paid in the form of two notes and
$2.0 million was paid in the form of shares of Common Stock. A $4.3 million
note is due on April 1, 2001 and principal is repayable in quarterly
installments. A $1.0 million note is due on April 1, 2000 and principal is
repayable in three equal annual installments. Both of the notes accrue
interest at the rate of 8.33% per annum, which is payable quarterly, except
that interest accruing on the $4.3 million note during the first year is added
to the outstanding principal amount of the Note. In May 1997, the Company,
through IMTCI, also acquired the capital stock of Crucible, a site management
organization with clinical investigational sites in Atlanta and Savannah and
an investigational affiliation in San Juan, Puerto Rico for $300,000 in cash.
The Company expects to continue to expand operations through internal growth
and acquisitions.     
 
  The Company has experienced significant growth through internal expansion.
Prior to the formation of the Company, which owns all of the shares of
Associates and IMTCI, the Company's business was conducted entirely through
Associates and its wholly-owned European subsidiary, PRA GmbH. Net revenues of
Associates and its subsidiary grew 75.8% from $12.2 million in 1995 to $21.5
million in 1996. The Company has subsequently supplemented internal growth
through acquisitions and may continue to do so in the future.
   
  The Company's backlog consists of anticipated net revenues from the
uncompleted portion of work from signed contracts and letters of intent. At
September 30, 1997, backlog was approximately $45.4 million, as compared to
$29.0 million at September 30, 1996, a 56.6% increase. Since the contracts
with its clients contain cancellation clauses and clients' needs and interests
change, the Company believes that its backlog as of any date is not
necessarily a meaningful predictor of future results and no assurances can be
given that the Company will be able to fully realize all of its backlog as net
revenue. See "Business--Backlog" and "Risk Factors--Loss or Delay of
Contracts; Pricing Under Contracts."     
   
  The Company's contracts generally have terms ranging from several months to
several years. A portion of the contractual fee generally is payable at the
time the contract is entered into, with the balance payable in installments
over the contract's term, in most cases upon the achievement of specified
milestones. Most of the Company's contracts are terminable upon 30 to 60 days'
notice by the client. Clients terminate or delay contracts for a variety of
reasons, including, among others, the failure of the product being tested to
satisfy safety requirements, unexpected or undesired clinical research 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. Although the Company typically is
entitled to receive certain fees for winding down a study which is terminated
or delayed and, in some cases, a termination fee, the loss or delay of a large
contract or the loss or delay of multiple contracts could have a material
adverse effect on the Company.     
   
  The Company has historically had very few receivables that it was unable to
collect due to credit or other problems. The Company regularly reviews its
billed and unbilled receivable balances and provides estimated reserves for
potential credit losses.     
 
                                      20
<PAGE>
 
   
  Revenues from contracts are generally recognized on a percentage of
completion basis as work is performed, measured by the total costs incurred as
a percentage of estimated total costs for each contract. The Company uses this
method because management considers total costs incurred to be the best
available measure of progress on these contracts. The estimated total costs of
contracts are reviewed and revised periodically throughout the lives of the
contracts with adjustments to revenue resulting from such revisions being
recorded on a cumulative basis in the period in which the revisions are made. A
significant portion of the Company's contracts undergo scope modification over
the contract period. Revenues related to contract modifications are recognized
when realization is assured and the amounts are reasonably determinable. As is
customary in the CRO industry, the Company routinely subcontracts with third
party investigators in connection with clinical trials and with other third
party service providers for laboratory analysis and other specialized services.
These costs and other reimbursable costs are passed through to clients and are
included in gross revenues in accordance with industry practice, and are then
deducted to arrive at net revenues. Consistent with industry practice, the
Company views growth in net revenues as its primary measure of revenue growth.
    
  Direct costs consist of compensation and related-fringe benefits for project-
related employees and support personnel, unreimbursed project-related costs and
allocated indirect costs, including facilities, information systems and other
costs. Selling, general and administrative expenses consist of compensation and
related fringe benefits for administrative, sales and marketing employees,
professional services, relocation, recruitment and advertising costs, as well
as unallocated costs related to facilities, information systems and other
costs.
   
  Contracts of PRA GmbH, a wholly-owned subsidiary, through which the Company
principally conducts its European operations, are generally denominated in
German marks. Because the majority of PRA GmbH's expenses are paid in such
currency, its earnings are not materially affected by fluctuations in exchange
rates. However, the Company's financial statements are denominated in dollars
and, accordingly, changes in the exchange rate between foreign currencies and
the United States dollar will affect the Company's financial results. The
Company's cumulative foreign currency translation adjustment as of September
30, 1997 and for the period commencing on January 1, 1997 was not material.
       
  Stock repurchase and other equity compensation consists of the repurchase of
certain shares immediately succeeding the exercise of employee stock options
and the amortization associated with stock options issued with an exercise
price less than the fair market value of the stock at the date of grant.     
 
  Since the Company conducts operations on a global basis, the Company's
effective tax rate has depended and will continue to depend on the geographic
distribution of its revenue among locations with varying tax rates. The
Company's results of operations will be affected by changes in the tax rates of
the various jurisdictions. In particular, as the geographic mix of the
Company's income before income taxes among various tax jurisdictions changes,
the Company's effective tax rate may vary from period to period.

NINE MONTHS ENDED SEPTEMBER 30, 1997 COMPARED TO NINE MONTHS ENDED SEPTEMBER
30, 1996     
   
  Net revenues for the nine months ended September 30, 1997 were $29.5
million, an increase of $14.6 million, or 97.5%, from $14.9 million for the
nine-month period ended September 30, 1996; $7.9 million of this growth was
from the Company's existing operations. This represents internal revenue
growth of 53.0% for the nine-month period ended September 30, 1997. The
increase in net revenues is due to the continued growth and expansion of
existing trials management centers, the opening of two new trials management
centers, enhanced business development efforts and the broadening of the
Company's service offerings; $6.7 million of this growth was from the
acquisitions of IMTCI and Crucible.     
   
  Direct costs for the nine-month period ended September 30, 1997 increased
approximately $10.8 million to $21.2 million from $10.4 million for the
similar period ended September 30, 1996. This increase in direct costs is
predominately due to the costs associated with the acquired businesses, the
expansion of facilities and increased associated headcount for the same
periods. Staff levels increased 151.6% from 244 to 614 full time equivalent
employees at September 30, 1996 and September 30, 1997 respectively. The large
increase in staffing levels is due to the workforce required to support the
increase in net revenues from existing contracts, required headcount additions
needed to facilitate the growth in backlog, anticipated contract scope
additions and modifications, and the previously mentioned acquisitions. This
increase also is due to the start-up of operations in San Francisco,
California and Lenexa, Kansas. In addition, the Company incurred a one-time
charge of approximately $150,000 in the nine-month period ended September 30,
1997 for the conversion of the Company to a more flexible benefits program for
its staff.     
   
  For the nine months ended September 30, 1997, selling, general and
administrative ("SG&A") expenses were $6.3 million, an increase of $3.4
million, from $2.9 million for the nine months ended September 30, 1996. The
Company's SG&A expenses increased due to costs associated with the businesses
it acquired during the nine-month period ended September 30, 1997.
Additionally, the increase in SG&A expenses is a result of the Company's
efforts to enhance its infrastructure, primarily in the areas of business
development, administrative staffing at the executive and professional levels
and increasing the number of employees in accounting, human resources and
other administrative areas, which reflects the growth and commitment to the
ongoing training and development of the Company's staff.     
   
  Depreciation and amortization increased $887,000 or 310.2% to approximately
$1.2 million for the nine-month period ended September 30, 1997 from $286,000
for the nine months ended September 30, 1996. This increase also was due to
the Company's geographic expansion with the opening of new trials management
centers and approximately $3.9 million of fixed asset purchases during the
nine-month period ended September 30, 1997. The majority of these expenditures
are related to the Company's continuing development of its integrated
information systems. In addition, a significant portion of the increase was
attributable to the amortization of goodwill associated with the acquisitions
of IMTCI and Crucible which totaled $185,000.     
   
  For the nine months ended September 30, 1997, stock repurchase and other
equity compensation totaling $33,000 consisted of amortization associated with
stock options issued with an exercise price less than the fair market value of
the stock at the date of grant. These options will vest upon the effectiveness
of the Offering. At that time, all remaining unamortized compensation expense
will be charged to earnings.     
 
YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
  Net revenues for 1996 were $21.5 million, an increase of $9.3 million, or
75.8%, from $12.2 million in 1995. This increase resulted principally from an
increase in the size, number and scope of existing contracts under management.
Net revenue growth during this period was solely from internal operations. The
Company was able to achieve this rate of growth while at the same time
maintaining a diversified portfolio with no single sponsor representing more
than 13% of consolidated net revenues.
 
                                      22
<PAGE>
 
  Direct costs increased by $6.7 million, or 81.0%, to $15.0 million in 1996
from $8.3 million in 1995. This increase as a percentage of net revenues from
67.5% in 1995 to 69.5% in 1996, reflects the Company's commitment to the
training and hiring of professional and technical staff in certain therapeutic
fields; and the requisite staffing levels associated with the volume of
workflow. The growth in direct expenses was also related to the start-up of
operations in Red Bank, New Jersey and Swansea, Wales.
 
  SG&A expenses were $4.2 million in 1996, an increase of $827,000, or 24.8%,
from $3.3 million in 1995. SG&A expenses decreased as a percentage of net
revenues from 27.3% in 1995 to 19.3% in 1996, due principally to the Company's
ability to spread these expenses over a larger net revenue base as the
Company's volume of business increased.
 
  Depreciation and amortization increased by 73.3%, increasing to $447,000 in
1996 from $258,000 in 1995. The increase was primarily attributable to
increased depreciation expense as a result of capital expenditures for the
Company's integrated information systems, office equipment, furniture and
leasehold improvements associated with the growth of the Company, including
the start-up of operations in Red Bank, New Jersey and Swansea, Wales.
 
  Simultaneously with the Company's sale of the Series A Preferred Stock in
October of 1996 the Company repurchased 1,545,540 shares of outstanding common
stock from certain investors and employees for approximately $9.2 million.
Approximately $633,000 of this amount was expensed as one-time compensation as
certain of the shares were repurchased immediately succeeding the exercise of
employee stock options. The Company also recorded compensation expense of
approximately $11,000 for options whose exercise price was less than the then
fair market value of the common stock as determined by an independent
appraisal. These two non-cash one-time items resulted in the stock repurchase
and other equity compensation expense in 1996 of $644,000. The Company also
recorded non-cash charges associated with the accretion of warrants for
Associates' common stock, totaling $1.9 million and with non-cash dividends on
the Company's Series A Preferred Stock totaling $344,000, which will be
forfeited at the closing of the Offering.
 
YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994
 
  Net revenues in 1995 were $12.2 million, an increase of $2.2 million, or
21.7%, from $10.1 million in 1994. This growth was solely from internal
operations and the increase in net revenues was primarily due to increases in
the number and size of contracts under management, expanded focus of the
Company on clinical trials management business development and increased
international revenues from its operations in Mannheim, Germany.
 
  Direct costs in 1995 were $8.3 million, an increase of $2.0 million, or
31.6%, from $6.3 million in 1994. The increase in direct costs was due to the
expansion of international capabilities and the growth of operational staff in
Germany. In addition, the Company experienced an increase in direct costs
because a significant potential contract, which the Company anticipated being
awarded, was not awarded by the sponsor due to adverse preclinical results.
 
  SG&A expenses were $3.3 million in 1995, an increase of $481,000, or 16.9%,
from $2.9 million in l994. As a percentage of net revenues, SG&A expenses
declined from 28.4% in 1994 to 27.3% in 1995. This decrease in SG&A expenses
as a percentage of net revenues was due to the Company's ability to spread
these expenditures over a larger revenue base.
 
  Depreciation and amortization declined by $24,000, falling to $258,000 in
1995 from $282,000 in 1994; due to the Company's large amount of capital
expenditures in previous years to support the growth of the business.
 
  During 1995, the Company recorded a non-cash charge of $715,000 for the
accretion of put provisions associated with various venture capital
financings. Those put provisions are no longer in effect.

ACQUISITIONS
 
  For the six-month period ended March 31, 1997, net revenues for IMTCI
increased $1.2 million, or 29.8%, to $5.2 million from $4.0 million for the
same six month period ended March 31, 1996. IMTCI's net revenues of $10.5
million for the fiscal year ended September 30, 1996 increased $1.6 million,
or 17.4%, from $8.9 million for the fiscal year ended September 30, 1995. Net
income at IMTCI declined $266,000 for the comparable periods ended March 31,
1997 versus March 31, 1996 due to its growth in infrastructure and staff
levels. Net income for the fiscal years ended September 30, 1996 versus
September 30, 1995 declined $206,000 with the expansion of infrastructure and
staff levels.
   
  Net revenues at Crucible grew to $984,000 for the year ended December 31,
1996 from immaterial net revenues in the previous year ended December 31, 1995
as the entity did not begin operations until December of 1995. Crucible
experienced a net loss of $37,000 for the year ended December 31, 1996 as a
result of start-up expenses.

  The Company's unaudited quarterly results have been, and are expected to
continue to be, subject to fluctuations. Quarterly results can fluctuate as a
result of a number of factors, including the commencement, completion or
cancellation of large contracts and the progress of ongoing contracts. A
portion of the services provided by IMTCI relate to health issues that are
seasonal in nature, resulting in IMTCI's financial results being somewhat
seasonal as well. Since a large percentage of the Company's operating costs
are relatively fixed, variations in the timing and progress of large contracts
can materially affect quarterly results. To the extent the Company's
international business increases, exchange rate fluctuations also may
influence these results. The Company believes that comparisons of its
quarterly financial results are not necessarily meaningful and should not be
relied upon as an indication of future performance. See "Risk Factors--
Variation in Quarterly Operating Results."

LIQUIDITY AND CAPITAL RESOURCES
   
  The Company historically has funded its operations and growth, including
acquisitions, with cash flow from operations, borrowings and sales of equity
securities. Other than in connection with the share exchange pursuant to which
the Company became the holding company of Associates and in connection with
the exercise of certain outstanding stock options and warrants, there were
only four issuances of equity securities over the last two years: (i) the
issuance in August 1995 of a warrant to purchase shares of Class C Common
Stock of Associates, constituting six percent of the fully diluted capital
stock of Associates, at that time to Sirrom Capital Corporation (whose
successor is Sirrom Investments, Inc.) in connection with a $2 million loan,
(ii) the issuance in December 1995/January 1996 of $500,000 of Class F
Preferred Stock of Associates to predecessors in interest to Virginia Capital,
L.P. and Sirrom Investments, Inc. and four members of the Company's
management, Earle Martin, James C. Powers, Joachim Vollmar and W. Bain
MacLachlan, (iii) the issuances in October and November 1996 of an aggregate
of approximately $19.37 million of Series A Preferred Stock and related
warrant agreements to certain affiliates of The Carlyle Group and to Virginia
Capital, L.P. and (iv) the issuance in April 1997 of $2 million of Common
Stock as part of the purchase price paid by the Company in connection with its
acquisition of IMTCI. Of the proceeds from the Series A Preferred Stock
issuance, approximately $9.2 million was used by the Company to repurchase
certain shares of, or options for, Common Stock, including approximately $7.0
million for the repurchase of shares of Common Stock from the founder of
Associates and certain of his family members. See "Certain Transactions."     
   
  Total capital expenditures were approximately $182,000, $506,000 and $2.5
million in 1994, 1995 and 1996, respectively, and have amounted to
approximately $3.9 million in the nine months ended September 30, 1997.
Computers, software, office equipment, furniture and facilities improvements
have accounted for a significant portion of the capital expenditures.     
   
  The CRO industry is generally not capital intensive. The Company's principal
cash needs on both a short-term and long-term basis are for the payment of
salaries, office rent and the travel expenditures of its clinical research
associates. The Company plans to continue to expand its investigational site
management business. In addition, the Company is implementing a new
information technology platform requiring anticipated capital expenditures of
approximately $6.7 million of which approximately $3.1 million has already
been spent over the nine-month period ended September 30, 1997. The Company
has historically financed these expenditures through operations and
borrowings.     
   
  The Company utilizes its working capital to finance operating expenses
pending receipt of its receivables. Contract payments by the Company's clients
vary according to the terms of each contract. Unbilled receivables have
increased $4.3 million from December 31, 1996 to September 30, 1997. A large
part of the increase is attributable to the increase in the Company's
revenues. Unbilled receivables were 11% of net revenues for the twelve months
ended December 31, 1996. For the twelve months ended September 30, 1997,
unbilled receivables were 16% of net revenues (as restated to include revenues
from IMTCI for the full twelve-month period). A portion of this increase is
attributable to the Company's newly acquired site management business.
Industry practice in this area has been not to collect funds in advance of
doing the work and, as a result, unbilled receivables are more significant.
For the twelve months ended September 30, 1997, unbilled receivables for the
site management business were 21% of related net revenues. The Company
historically has had no material difficulties in collecting amounts associated
with its unbilled receivables balance and expects to collect the full balance.
       
  The Company recently established the Credit Facility, which is a $7.5
million secured revolving credit facility with First Union National Bank
("First Union") maturing on June 30, 1999. The Company's obligations in
respect of the Credit Facility are guaranteed on a secured basis by each of
Associates, IMTCI and Crucible. The Company intends to repay any outstanding
balances under the Credit Facility with a portion of the net proceeds of the
Offering. After the completion of the Offering, the Company intends to
increase the Credit Facility to $17.5 million and First Union has committed to
make such increase subject to the satisfaction of certain conditions. PRA GmbH
has a 1.0 million German mark (approximately $568,000) line of credit facility
with Deutsche Bank AG, which is secured by an assignment of PRA GmbH's
receivables.     
 
  The Company expects to continue expanding its operations through internal
growth and strategic acquisitions. The Company expects that such activities
will be funded from existing cash and cash equivalents, cash flow from
operations, the net proceeds of the Offering, borrowings under the Credit
Facility or other credit facilities and, possibly, the issuance of
 
                                      25
<PAGE>
 
   
equity or debt securities. The Company believes that available cash, together
with cash flow from operations, borrowings under the Credit Facility and other
lines of credit and net proceeds from the Offering, will be sufficient to fund
the Company's current operations for at least the next twenty-four months.
Although the Company has no present acquisition agreements or arrangements,
there may be acquisition or other growth opportunities that require additional
external financing, and the Company may from time to time seek to obtain funds
from public or private issuances of equity or debt securities. There can be no
assurances that such financings will be available on terms acceptable to the
Company.     
 
CHANGE IN ACCOUNTANTS
 
  Pursuant to a letter dated February 7, 1997 from Patrick K. Donnelly to
Ernst & Young LLP ("E&Y LLP"), the Company dismissed its accountants, E&Y LLP.
This decision was recommended by the audit committee of the Company's Board of
Directors and approved by the Company's Board of Directors.
 
  E&Y LLP's report for the years ended December 31, 1993, 1994 and 1995 did
not contain an adverse opinion or disclaimer of opinion and was not qualified
or modified as to uncertainty, audit scope, or accounting principles.
Furthermore, during the entire period that the Company had engaged E&Y LLP and
up until the time of E&Y LLP's dismissal, there were no disagreements between
the Company and E&Y LLP on any matter of accounting principles or practices,
financial statement disclosure or auditing scope or procedure that, if not
resolved to E&Y LLP's satisfaction, would have caused it to make reference to
the subject matter of such disagreements in connection with its report.
 
  In January, 1997, the Company engaged Arthur Andersen LLP as the Company's
principal accountants. This engagement was recommended by the audit committee
of the Company's Board of Directors and approved by the Company's Board of
Directors. Prior to their engagement, the Company did not consult with Arthur
Andersen LLP with respect to any substantive matter, including the application
of accounting principles, audit opinions, any reporting issue, any
disagreement with the former accountant or any reportable event.

                                   BUSINESS
 
GENERAL
   
  PRA International, Inc. (the "Company") is a leading contract research
organization ("CRO"), providing clinical research and development services on
an international basis to the pharmaceutical and biotechnology industries. The
Company believes that, based on net revenues, it is one of the 10 largest
full-service CROs in the world focused on managing human clinical trials. It
also believes that it is one of only several of these CROs capable of
providing a full range of clinical development services on an international
basis. Since January 1, 1996, the Company has conducted 288 programs for 68
sponsors, including 22 of the 25 largest international pharmaceutical
companies in the world as measured by revenues and 11 of the 25 largest
biotechnology companies in the United States as measured by market
capitalization. The Company currently has preferred provider relationships
with eight pharmaceutical and biotechnology companies and is one of the three
principal vendors of CRO services at another seven pharmaceutical and
biotechnology companies. The Company's pro forma net revenues for the nine
months ended September 30, 1997, giving effect to the April 1, 1997
acquisition of International Medical Technical Consultants, Inc. ("IMTCI") as
if it had occurred on January 1, 1997, were approximately $32.4 million and,
on September 30, 1997, it had 614 employees.     
 
  The Company offers a full range of services on a global basis that comprise
the clinical development process, from preparation of Investigational New Drug
("IND") applications and first-administration-in-man (Phase I) studies,
through large-scale clinical trials (Phases II--III) studies, to product
marketing registration in the United States and Europe and post-marketing
(Phase IV) studies. Specific services performed by the Company include
clinical program development, study protocol design, project management,
investigational site selection, regulatory document management, study
compliance monitoring, medical monitoring, data collection and management,
biostatistical analysis, medical writing and regulatory document preparation
and submissions. In addition to these standard services, the Company offers
specialized services that it believes enables it to offer greater value to its
clients. These services include single site proof of concept studies, senior
level strategic advisory services, investigational site management services, a
centralized Investigational Review Board ("IRB"), and long term safety
assessment and reporting services.
   
  The Company has provided clinical research and development services in North
America since 1982 and in Europe since 1992. The Company conducts its
operations through four trials management centers in the United States located
in Virginia, Kansas, New Jersey and California, one European trials management
center located in Mannheim, Germany, a 56-bed inpatient facility and a
dedicated outpatient clinic in the Kansas City area, seven investigational
sites located in the Kansas City area, Atlanta and Savannah as well as an
investigational affiliation in San Juan, Puerto Rico, and a data management
center in Swansea, Wales. The Company also plans to begin operations in the
London, England area in early 1998. In 1996, the Company derived 69% of its
net revenues from United States operations and 31% of its net revenues from
European operations and, for the nine months ended September 30, 1997, it
derived 82% of its net revenues from United States operations, the increase
being largely due to two acquisitions in the United States, and 18% from
European operations.     
 
  The Company utilizes a decentralized operating model that empowers local
professionals at each of the Company's trials management centers to make key
operational decisions while supporting large-scale, global trials. By
strategically locating full service trials management centers near major
sponsors and permitting each center to be responsive to clients, the Company
believes it enhances service quality and client relationships. All of the
Company's trials management centers are integrated through shared business
practices, standard operating procedures and common information systems. As a
result, each trials management center can deliver services reflecting the
international expertise, support and resources of the entire Company.
   
  The Company believes that its depth of clinical management is significant
and that, drawing on these resources, it has developed significant expertise
in clinical development as well as in a number of therapeutic areas. The
Company's staff of approximately 614 employees includes an extensive roster of
senior level     
 
                                      27

scientific, regulatory and clinical experts providing direction and oversight
to clinical development projects and day-to-day operations, including
approximately 16 who are M.D.s, 35 who have Ph.D.s, 3 who are Pharm.D.s, and
74 others who have master's level degrees. In addition, the Company has
retained a number of distinguished industry advisors and consultants who
assist as needed in providing input into drug development and regulatory
approval strategies for clients and in developing recommendations concerning
potential improvements to the Company's clinical development procedures. The
Company believes that it has established significant expertise in a number of
therapeutic areas, namely oncology, central nervous system disorders,
cardiovascular diseases and allergy and respiratory conditions.     
 
INDUSTRY OVERVIEW
 
  The clinical testing and regulatory approval process for new drugs and
biological products is expensive and time-consuming. The CRO industry, which
has developed over the past twenty years, has enabled pharmaceutical companies
and other drug development sponsors to contract out portions of the clinical
development process to specialists with the resources and expertise to perform
studies and other services faster and at lower cost than most sponsors are
able to achieve internally. CROs also allow sponsors to shift the significant
fixed labor costs inherent in establishing this function in house to variable
costs through the outsourcing of these services. In addition, the largest CROs
enable resource constrained biotechnology companies to outsource all aspects
of their clinical development requirements. By performing drug studies faster,
CROs provide sponsors the economic advantages of early market entry as well as
extending the period during which their products benefit from patent
protection.
   
  CROs derive substantially all of their revenues from the research and
development expenditures of sponsors. The CRO industry has evolved from its
early days in the 1970s, when it provided limited clinical services, into a
full-service industry that encompasses the entire clinical research and
development process, including preclinical services, clinical study planning
and design, regulatory consulting, clinical trials management, investigational
site management, data management, biostatistical analysis, and long term
product safety management. All of these services must be provided in
accordance with applicable international governmental regulations covering
clinical trials and the drug approval process in the jurisdictions in which
the services are provided. These services must be tailored to meet these
regulations simultaneously, including the regulations of the Food and Drug
Administration ("FDA") in the United States and the European Medicines
Evaluation Agency ("EMEA") in Europe.     
 
  In 1996, worldwide expenditures on research and development by
pharmaceutical, biotechnology and medical device companies are estimated to
have been $35.0 billion, of which the Company estimates $18.0 billion was
spent on drug development activities of the type offered by the CRO industry.
The Company believes that approximately $3.0 billion of such spending was
outsourced to CROs for traditional trials management services and an
additional $3.0 billion was spent on grants to investigational sites.
 
  In general, the CRO industry is not capital intensive and the costs of entry
into the industry are relatively low, though there has been an increase in
those costs over the past few years due to industry consolidation and the
demand for expertise and global capacities for larger programs. Because of
this historic ease of entry, the industry is highly fragmented, with several
hundred small, limited service providers, several dozen medium-sized firms and
several full-service CROs with international capabilities. Although there are
few barriers to entry for small, limited-service providers, there are
significant barriers to becoming a full-service CRO with international full
drug development program capabilities. Substantial financial resources, a
developed infrastructure and operational experience are required to develop
broad therapeutic expertise, manage and conduct complex clinical trials,
coordinate trials at both domestic and international locations, prepare multi-
national regulatory submissions and conduct large clinical programs with the
level of control and quality currently required by sponsors. The barriers to
becoming a full-service CRO combined with the expansion of some larger CROs
have led to an increased rate of industry consolidation.

INDUSTRY TRENDS
 
  The Company believes that increased outsourcing of drug development
activities by sponsors has led to significant growth in the CRO industry.
Although there can be no assurance that this growth will continue or even
remain at existing levels, the Company believes that this growth should
continue for the following reasons:
 
 Cost Containment Pressures
 
  Cost containment pressures on pharmaceutical companies arising from market
acceptance of generic drugs, managed care and impending patent expirations
have led to increased scrutiny of product development expenditures. The
Company believes the pharmaceutical industry is responding by consolidating
and reducing jobs, centralizing the research and development process and
outsourcing to CROs creating variable costs, thereby reducing the fixed costs
associated with internal drug development. The CRO industry, by specializing
in clinical trials management, is often able to perform the needed services
with a higher level of expertise or specialization, more quickly and at a
lower cost than could the client if it were to perform these services
internally.
 
 Globalization of Drug Development
 
  Many sponsors are attempting to develop products and file for regulatory
approval simultaneously in the United States and Europe, rather than following
the past practice of sequential filings. The clinical studies to support such
development and registration efforts often include a combination of multi-
national European and United States trials. Sponsors may turn to CROs for
assistance in designing and implementing such trials as well as assistance in
obtaining global regulatory approvals. The Company believes CROs with
integrated global capabilities will benefit from this trend.
 
 Increasingly Complex Trials
 
  Regulations regarding the development and approval of drugs and biological
products have become increasingly stringent in both the United States and
Europe, resulting in a need for more complex and often larger clinical
studies. These trends have created an increased demand for high level
consulting services as well as enhanced capabilities in program management and
logistics, large-scale data collection and analysis, and the related need for
greater technological capabilities to track and control clinical studies,
manage clinical data and ensure its reliability, and expedite the review and
approval process. As a result, the pharmaceutical and biotechnology industries
are increasingly outsourcing to CROs to manage the added workloads created by
these regulatory requirements and to take advantage of their data management
expertise, technological capabilities and global presence.
 
 Biotechnology Industry Growth
 
  The United States biotechnology industry has grown rapidly over the last ten
years and has developed a significant number of new drug candidates that are
now entering the clinical phase of development. According to the
Pharmaceutical Research and Manufacturers of America, from 1989 to 1996, the
number of biotechnology products in clinical trials rose from 80 to over 280,
an annual compounded rate of growth of approximately 20%. Many biotechnology
companies do not have the necessary staff, expertise or financial resources to
conduct clinical trials in house and obtain regulatory approval on their own.
Accordingly, many biotechnology companies have chosen to use CROs rather than
spend significant time and resources to develop an internal clinical
development capability. The biotechnology industry is now also expanding into
and within Europe, providing growth opportunities for CROs with international
capabilities that have experience with biotechnology companies' requirements
and compounds. The Company believes it will benefit from this trend due to its
integrated European capabilities and significant experience working with
biotechnology companies.
 
 Increased Use of Preferred CROs and Increase in Average Contract Size
 
  As the CRO industry has matured and pharmaceutical and biotechnology
companies have gained increased confidence in CROs, certain sponsors have
begun to work primarily with a limited number of preferred provider
 
                                      29
<PAGE>
 
CROs and contract size has increased. Whereas sponsors initially contracted
with CROs for selected portions of clinical studies, such as clinical
monitoring or data management, some sponsors are now outsourcing drug
development in its entirety including planning, design and implementation of
entire drug development programs. While these programs are typically awarded
in stages, they can involve total net revenue of $20 million or more. The
Company believes that these factors are further fueling the growth of larger
CROs capable of conducting international clinical development.
 
 Increased Emphasis on Therapeutic Expertise and Value-Added Services
 
  The Company believes there is an increasing need for therapeutic expertise
in order for a CRO to obtain contracts relating to a particular therapeutic
area. In addition, sponsors have increased their demand for value-added
services from CROs, such as consulting and advisory services and site
management organization ("SMO") services. The Company believes that CROs such
as itself that offer therapeutic expertise in targeted specialty areas and
advisory, SMO and other value-added services will likely be the greatest
beneficiaries from these trends.
 
COMPANY STRATEGY
 
  The Company's goal is to maintain and enhance its position as an industry
leader in the delivery of reliable, high quality, cost-effective and timely
clinical development services enabling sponsors to bring new health care
products to market faster and more efficiently. Key elements of the Company's
strategy to achieve its goal are described below.
 
 Offer Comprehensive Range of Clinical Development Services
 
  The Company plans to retain its focus on clinical development services, from
preparation of INDs and first-administration-in-man through international
marketing registrations, and continue to enhance and expand its full range of
services in this market on an international basis. The Company believes that
CROs able to offer a full range of product development services are more
attractive to sponsors because using a single CRO can simplify the process for
the sponsor and increase the speed, integration and accuracy of clinical data
collection. The Company currently offers a full range of global services that
encompasses the clinical development process, including drug development and
regulatory approval strategies, protocol design, initiation and management of
Phase I--IV clinical trials, data management, analysis and reporting and
regulatory support services. By continuing to focus on clinical development
services, the Company believes it can maintain and expand its core business,
while providing high levels of quality and reliability.
 
 Expand and Enhance Areas of Therapeutic Expertise
 
  The Company believes its experience and expertise in certain therapeutic
areas as well as its ability to provide specialized value-added services
enhances its credibility with sponsors and improves overall quality. For
instance, the Company not only has significant expertise in allergy and
respiratory disease, but also owns and operates a therapeutic specialty center
in the allergy and respiratory disease areas with dedicated inpatient and
outpatient clinics. The Company also believes it has established significant
expertise in oncology, central nervous system disorders and cardiovascular
diseases. The Company plans to continue to enhance its ability to deliver high
quality global expertise in targeted therapeutic areas, including preparation
of full clinical development plans, design of study protocols, and efficient
conduct of early proof-of-concept studies, by developing or acquiring
additional therapeutic specialty centers.
 
 Provide Specialized Services
 
  In addition to establishing areas of therapeutic expertise, the Company
provides a number of value-added services that differentiate the Company from
other CROs of similar size and some that are larger. These include
comprehensive senior level advisory services related to drug development and
regulatory approval strategy,
 
                                      30
<PAGE>
 
design and conduct of full drug development programs, investigational site
management services, safety management services, and supporting specialty
services such as centralized patient enrollment support and a centralized IRB.
 
 Continue to Invest in Integrated Information Systems
 
  The Company currently operates an international client-server network that
supports both centralized and distributed Oracle-based applications, advanced
PC-based professional office applications and high level end-user reporting
tools. The Company is expanding its existing integrated clinical operations
information system so as to enable users anywhere in the world to monitor or
manage all aspects of a drug development program conducted by the Company. The
system is designed to integrate a full suite of clinical development
applications including clinical study management, protocol design, patient
enrollment, investigational site administration, source document and case
report form ("CRF") data capture and management, safety monitoring and
reporting, data management, statistical analysis, reporting and regulatory
document submission.
 
 Grow Internally and Through Selected Acquisitions
 
  The Company intends to continue to grow internally and through acquisitions.
To this end, the Company may pursue selected acquisitions that enhance its
geographic presence, enlarge the scope of its therapeutic expertise, enhance
its access to investigational sites or enable it to provide value-added
specialty services.
 
SERVICES
 
  The Company's services are comprehensive and are packaged to meet the unique
requirements of each program for each sponsor. Specific services are outlined
in more detail below and are viewed by the Company as falling into two general
categories. The first category includes the component services that form the
core of the Company's clinical trials management business. The second category
includes services that enable the Company to offer broader solutions and
higher value to its clients and, in some instances, go beyond traditional CRO
capabilities.
 
 Core Clinical Trials Services
 
  Study Protocol Design. The study protocol defines the medical issues to be
examined in evaluating the safety and efficacy of the drug under study, the
number of patients required to produce statistically valid results, the
clinical tests to be performed in the study, the time period over which the
study will be conducted, the frequency and dosage of drug administration and
the exact inclusion and exclusion criteria to be met for the patients enrolled
in the study. The success of a study depends not only on the ability of the
protocol to predict correctly the requirements of regulatory authorities, but
also on the ability of the protocol to fit coherently with the other aspects
of the development process and the ultimate marketing strategy for the drug.
 
  Case Report Form Design. Once the study protocol has been finalized, CRFs
must be developed to record the information obtained from the clinical
studies. Various technical disciplines involved in the drug development
process must work closely together to assure that the CRF is the most
efficient for collection of clinical data and subsequent data entry,
management and reporting. Proper CRF design is critical to enable
investigators and field monitors to conduct their respective jobs quickly,
accurately and effectively.
 
  Phase I and Phase II Single Site Studies. The Company offers Phase I
clinical testing services through its 56-bed inpatient facility located in
Lenexa, Kansas. The facility has conducted more than 250 dose escalation,
pharmacokinetic, pharmacodynamic and radio-labeled drug studies and is
equipped with state-of-the-art diagnostic, monitoring and testing equipment to
address a wide variety of study requirements. The Company also conducts early
Phase II proof-of-concept studies at its facilities in Lenexa, Kansas. At this
facility, the Company has the ability to conduct single site inpatient and
outpatient studies and handle a large number of patients in a short time
period.
 
                                      31
<PAGE>
 
  Clinical Trials Management. The Company conducts Phase II-IV clinical trials
through a dedicated project teams that consist of staff from clinical
monitoring, data management, medical affairs, statistical and regulatory
departments, keeping the makeup of the team stable throughout the life of the
project. A project team could be comprised of representatives from multiple
regional centers and from various international locations. A project manager
supervises all aspects of the clinical trial and is responsible for meeting
the project's schedule and budget as well as for managing and meeting customer
expectations. Each of the Company's project managers has a minimum of six
years of clinical study experience. The Company believes that its approach to
project management provides a high level of quality as well as a
responsiveness to customer needs.
 
  Investigator Recruitment. During a clinical trial, administration of the
experimental drug to patients is supervised by physician investigators at
hospitals, clinics or other locations. The Company generally enters into an
independent contractor relationship with the investigators to perform this
work. The successful rapid identification and recruitment of investigators who
have the appropriate expertise and base of patients to satisfy the
requirements of the study protocol are critical to the timely initiation and
completion of the trial. In addition to using its own SMO sites, the Company
maintains and continually expands and refines a computerized database of
independent investigators to assist project managers in identifying
investigational sites for a particular study.
 
  Study Monitoring. The Company provides study monitoring services, which
include: investigational site initiation, patient enrollment assistance, data
collection and auditing for regulatory compliance, adherence to Good Clinical
Practices ("GCP") and compliance with study protocols. The Company
distinguishes itself from many of its competitors by hiring only experienced
health care professionals as field monitors, both to maintain higher quality
and to perform field monitoring in a more timely manner than possible with
less experienced staff. The Company's study monitoring services enable it to
obtain patient data from the field efficiently, quickly and accurately to
speed subsequent data entry, management and analysis, and report writing. The
Company's key focus is upon ensuring the reliability of the data. This is
accomplished by maintaining high quality data collection procedures. With
reliable data, the Company is able to prevent delays in clinical trials that
would otherwise result from re-collection or reconfirmation of inaccurate
data. The Company acquires data via electronic means, through visits by its
field monitors to investigational sites, and by its coordinators on location
at the Company's own SMO sites.
 
  Medical Monitoring. The Company retains medical doctors on its staff in
clinical trials management centers to assist the project teams, provide
training in therapeutic areas for clinical monitors, and monitor and report in
a timely manner any adverse events detected in any of its clinical trials.
 
  Data Management and Biostatistical Services. The Company provides clients
with data management and biostatistical services in various areas such as:
study design, sample size determination, case report form design and
production, data analysis plans, patient randomization, fax-based data
collection and monitoring, database design and construction, regulatory
document preparation, biostatistical analysis and presentation of clinical
study results to the FDA. The Company also provides database integration
services in which it consolidates and harmonizes data collected from many
clinical studies into a single integrated database for further analysis and
regulatory submissions. Drug development time is reduced by performing data
management and biostatistical analysis activities in parallel with other drug
development activities where possible. For example, data management personnel
work with clinical project managers and field monitors to continuously enter
data, program statistical tables and validate the database so that there is a
rapid progression from data entry to database freeze, and then to statistical
analyses. Similarly, there is a close working relationship between medical
writing and regulatory services personnel.
 
  Medical Writing and Regulatory Support. The Company provides medical,
statistical and integrated report writing services to assist sponsors in
presenting study findings, and regulatory services to assist in the
preparation and submission of regulatory filings. These services are fully
integrated into the Company's clinical study project plans and are generally
performed by Ph.D. level staff.
 
                                      32
<PAGE>
 
 Additional Value-Added Services
 
  Strategic Advisory Services. The development of drug development programs
and regulatory approval strategies is a critical area for the Company as, more
and more frequently, sponsors request that the Company take responsibility for
the design and management of entire drug development programs. In response,
the Company established a business unit, PRA Strategic Advisory Services, to
supply the skills and competencies necessary for delivering its high level
consulting services. The PRA Strategic Advisory Services group consists of
full time senior members in major functional disciplines, a Scientific
Advisory Board, retained consultants that are nationally or internationally
recognized scientific and clinical experts, and its senior operations
management team. This group provides consultation on global regulatory
strategy plans, drug development program plans, clinical study project plans
and similar high level plans as part of its strategy to obtain and implement
large-scale contracts.
   
  Investigational Site Management Services. The Company offers investigational
site management services both in conjunction with its other CRO services and
as a separate service sold directly to sponsors and others. The Company's site
management services are conducted through an independent subsidiary with
separate operations management from the Company's trials management business
at seven investigational sites in the Kansas City area, Atlanta and Savannah
as well as through an investigational affiliation in San Juan, Puerto Rico.
This separation of operations permits clinical monitors to be completely
independent of the investigational sites that they monitor and audit, as well
as allowing the Company to market its SMO services to other CROs. The
Company's model for its SMO services is to enter into exclusive contracts with
the investigators at each site, under which they agree to provide the Company
with office space for its staff and to perform medical evaluations and
procedures on a fee-for-service basis in strict accordance with study
protocols. The Company staffs the sites with its own study coordinators
(generally registered nurses with experience in managing clinical studies),
trains the physicians in the fundamentals of clinical research and in the
specifics of each study placed at their site, manages study-related regulatory
issues, schedules and manages all subject screening and follow-up visits,
performs sales and marketing functions and provides all other business support
functions required to conduct clinical studies. Through this relationship, the
Company seeks to achieve a substantial degree of control over the manner in
which the clinical research is conducted while its physician-investigators
receive early access to important new therapies and an additional stream of
revenue from existing patients. The Company seeks to enter into contracts with
investigators that contain standard non-compete clauses that prohibit them
from working with other SMOs.     
 
  The Company believes that its SMO services are attractive to sponsors since
these services allow them to avoid the delays of up to several months in
initiating large clinical studies due to the need to negotiate contracts with
the many investigators involved and obtain IRB approvals from the institutions
with which these investigators are associated, as well as delays caused by
slow enrollment at certain sites where clinical studies may receive lower
priority than other clinical activities. Sponsors conducting studies in the
Company's areas of therapeutic expertise also will benefit from the Company's
access to investigational sites that specialize in these areas. In the future,
the Company intends to expand its number of SMO investigational sites to the
extent that demand for SMO services continues to exist and the provision of
these services continues to be consistent with the Company's overall business
strategy.
 
  Safety Management Services. The Company provides management consulting on
drug safety issues, integration of clinical databases for analysis of short
and long term drug safety and tolerability, routine assessments of adverse
drug reactions, periodic reporting to regulatory agencies and single case
reports of adverse events associated with ongoing clinical studies through its
Safety Management Centers in Charlottesville, Virginia, Red Bank, New Jersey,
and Mannheim, Germany. Safety issues may lead to premature drug withdrawals
from the market and thereby limit the life cycle of a product, resulting in
financial losses. Drug safety activities are determined by national
legislation and involve personal liability of pharmaceutical manufacturers in
some countries. Timeframes for fulfilling reporting requirements are strict
and of critical importance to the pharmaceutical companies. Excellent routine
performance may protect sponsor organizations
 
                                      33
<PAGE>
 
against safety issues or at least limit their impact on the individual
company. Some organizations, especially biotechnology, companies that sell
over the counter products, and certain foreign companies operating in Europe
and the United States, are not well prepared to fulfill the international
regulatory requirements because of the lack of a well established in house
drug surveillance system.
 
  Centralized Investigational Review Board.  The Company provides IRB services
to its own investigational sites and to others through a board of independent
outside participants. Centralized IRB services help expedite clinical trials
by reducing the amount of time needed to initiate investigational sites and to
approve changes to the study protocol, informed consent form and other
documents.
 
  Patient Recruitment Services. The Company operates a centralized patient
recruitment center that prepares and places media advertising and operates
inbound and outbound telemarketing services to assist investigational sites in
identifying and enrolling subjects.
 
  Data Management Center.  The Company operates a high throughput data
management center in Swansea, Wales where CRF pages are scanned into
electronic image databases and prepared for analysis.
 
  Therapeutic Specialty Center. The Company operates a therapeutic specialty
center in the areas of asthma, allergy and pulmonary disease, which has
dedicated inpatient and outpatient clinics and associated specialized
equipment and procedures. Access to additional therapeutic expertise is
available through the Company's affiliated sites.
 
CUSTOMERS AND MARKETING
 
  The Company's marketing activities are conducted by the Company's senior
operations management and staff and by dedicated account executives who
identify prospective new business and coordinate the staff involved in a
typical sales cycle. New sales opportunities generally are identified through
industry contacts, routine marketing programs conducted by account executives,
operations staff relationships with sponsors and attendance at industry trade
shows and scientific meetings. In addition to account executives assigned to
each regional trials management center and site management center, the Company
expects each of its senior operations managers to actively solicit new
business from existing accounts and from their contacts within the industry.
The Company has worked with 22 of the top 25 largest international
pharmaceutical companies in the world as measured by revenues, and 11 of the
25 largest biotechnology companies in the United States as measured by market
capitalization, and has preferred provider relationships with several of these
companies. Since January 1, 1996, the Company has provided services to 68
sponsors in connection with 288 programs.
 
  To be a "preferred provider" in the CRO business means to be among the pre-
qualified CRO service providers a pharmaceutical or biotechnology company
ordinarily utilizes for clinical trial services, pursuant to previously
established forms of agreements and documents. Preferred provider
relationships are not contractual and there is no obligation on the part of a
customer to use any particular preferred provider in connection with a
proposed clinical trial or, in fact, to use a preferred provider at all. There
is no preferential pricing associated with any of the Company's preferred
provider relationships. This preferential relationship, however, is highly
valued in the CRO industry in order to obtain access to a significant amount
of potential business with a sponsor and a steady stream of projects of
varying sizes that assist in maintaining a high level of staff utilization.
The Company believes that high staff utilization is a primary determinant of
profitability for CROs. Sponsors expect the Company to be responsive in its
preferred provider relationships, and sponsors benefit from the Company's
familiarity with their internal business practices and operating procedures.
 
  The Company believes that concentration of business among certain large
clients is not uncommon in the CRO industry. It has taken certain steps to
mitigate this risk, including its regional operations strategy, which allows
for simultaneous development of a number of key accounts by senior operations
staff in each of its five trials management centers, and a general business
development strategy that focuses on the development of preferred provider
relationships with a wide array of sponsors. However, with the market shift
toward awarding
 
                                      34
<PAGE>
 
   
larger and larger program responsibilities to CROs, the Company may, from time
to time, have a significant percentage of its resources attributable to
several sponsors with which large international trials are then in progress.
In 1995, two clients accounted for approximately 13% and 11% of the Company's
net revenues. During 1996, two different clients accounted for approximately
13% and 11% of the Company's net revenues. For the nine-month period ended
September 30, 1997, two different clients accounted for approximately 15% and
10% of the Company's net revenues. The client that represented the largest
percentage of IMTCI's revenues (33% for the six months ended March 31, 1997
and 22% for the year ended September 30, 1996) was also a sizable client of
the Company prior to the IMTCI acquisition. The Company previously had an
ongoing relationship with this client (a large pharmaceutical company) and
believes that its relationship with this client will be maintained and that it
may be strengthened with the additional breadth of services offered by, and
resources available from, the expanded Company. IMTCI's other significant
client (also a large pharmaceutical company) represented 18% of net revenues
for the year ended September 30, 1996 but represented less than 10% during the
six months ended March 31, 1997. The Company believes that the acquisition
will have no impact on its relationship with these clients. Due to the nature
of the Company's business, it is not unusual for the revenue from a current
significant customer in one period to be a smaller percentage of total revenue
in another period. The Company does not have any other type of relationship
with any of its significant clients.     
 
INFORMATION TECHNOLOGY
   
  The Company believes that effective use of information technology is
critical to its ability to implement its strategy and that corporate
applications, databases, and network services should act as a unifying
structure, which supports communications, integration of project teams and
collaboration among staff associated with any Company business located
anywhere in the world. It believes that its investment in information
technology has and will continue to result in systems that expedite the
clinical development process, provide information that permits timely
monitoring and control of both projects and overall business performance, and
generally provide opportunities for competitive differentiation. For the nine-
month period ended September 30, 1997, the Company invested approximately $3.1
million in systems and technology, and it expects to continue to invest at
this level for the foreseeable future. It has developed a sophisticated
information management infrastructure and established state-of-the-art
business practices for the management and implementation of advanced
information systems.     
 
 Technical Platform
 
  The Company's goal is to maintain a flexible and adaptable technical
environment that facilitates the exchange of information among applications,
provides for ready access by business users to data for ad hoc analysis and
reporting, and simplifies integration of new applications into the existing
environment. Toward this end, the Company has implemented a standardized
technical architecture that supports traditional centralized applications,
distributed client/server applications and web-based applications, and
provides for loose integration between applications through a common ORACLE(R)
database. The Company supports standardized access by its clients and more
than 450 internal PC users through a worldwide wide area network, common and
centrally managed desktop configurations for all users and a consistent,
business-user-oriented graphical user interface.
 
 Clinical Operations Applications
 
  The Company's goal is to implement an integrated clinical operations
information system that enables users anywhere in the world to monitor or
manage all aspects of a program conducted by the Company through a
standardized desktop user interface, with a full suite of applications
including protocol design, investigational site administration, patient
enrollment, source document and CRF data capture and management, safety and
adverse event monitoring and reporting, study management, statistical
analysis, reporting and regulatory document submission. The Company believes
that its integrated clinical operations information system enables it to
conduct clinical development operations with greater quality and efficiency.
 
  The Company currently operates a number of proprietary production
applications, including:
 
    PRA Generic Data Entry--a flexible system for setting up clinical study
  databases, entering CRF data, providing quality control including automated
  data checking, query management and exporting completed
 
                                      35
<PAGE>
 
  databases to other application software for analysis. The system also
  supports coding of diagnoses, adverse events and similar medical
  information from multiple standard or client-specific dictionaries and
  production of data listings, summary tables and other reports for
  preliminary data analysis.
 
    PRA CRF--Image--a system of high speed scanners and software that allows
  CRFs collected at a Company regional center to be immediately scanned,
  transferred to the Company's centralized data management center in Swansea,
  Wales, entered into structured databases and made available over the
  network to users anywhere in the world. The system allows users access to
  both CRF images and the actual structured study database presented in a
  format similar to the original CRF, thus facilitating resolution of data
  problems or discrepancies.
 
    PRA Investigator Recruitment--a system that provides a database of
  potential investigators, generates site initiation packages that are
  shipped as part of the investigator recruitment process, tracks patient
  enrollment in ongoing studies and all associated regulatory documents and
  generates project status reports.
 
    PRA Study Manager--this system is a combination of proprietary and
  commercial software that allows the Company to track, at the level of an
  investigational site, study budgets, patient enrollments and key study
  events. The Company is in the process of migrating this system to its new
  technology platform and implementing major enhancements that will better
  support expansion of its site management operations.
 
    PRA Trials Manager--a proprietary system used by clinical research
  monitors to create and file site visit reports, track administrative site
  data on their laptop PCs and electronically transmit information into the
  PRA network for access by project managers.
 
  In addition to the proprietary systems mentioned above, the Company
currently operates a number of commercial software packages including Domain
Clintrial(R), DataFAX(R), and DZS Clinplus(R)for various data management
functions, the SAS System(R) for data analysis and reporting, Clinarium
ARIS(R) for safety management and adverse event reporting and MS Project(R)
and Time Line(R) for project management reporting.
   
  In order to address any potential Year 2000 issues, the Company has either
obtained new software or modified existing software and intends to replace any
potentially problematic software during 1998. The Company has budgeted for the
costs of such replacement.     
 
 Business Management Applications
 
  The Company operates a number of information systems in support of its
business operations. The most substantial applications in its business
management applications portfolio include the following:
 
  Office Productivity.  The Company supports a standardized suite of office
productivity applications on every desktop that enables efficient
communication among its staff worldwide through immediate sharing of
documents, schedules, presentations, business graphs, spreadsheets, databases
and other time-sensitive information. The Company believes that these are
important tools due to the information intensive nature of the product it
produces and is committed to the use of information technology to improve the
productivity of its professional staff. Additional productivity projects
planned or in pilot mode include desktop video conferencing, the ability to
send facsimiles from any PC on the network, and an active web page for public
access to Company information.
 
  Management Controls. The Company operates a proprietary management
information system that allows it to track, on a weekly basis, staff
utilization, project completion and work-in-progress status and resources
applied to projects and to compare actual results against plan. The system is
based on a time card entry module used by all employees that allows the
Company to track project work at an activity level and use this information
for routine management reporting and to improve both work processes and bid
estimates on future projects. The system is currently being enhanced to
integrate information on project bids and contracts, employee skills, sales
forecasting and other business modules.
 
                                      36
<PAGE>
 
  Financial Reporting. The Company currently operates separate accounting
systems among its operating units due to recent acquisitions. It is in the
process of consolidating these accounting systems into a single, high-end
commercial package that will enable better management of the issues it faces
as an international company, such as multi-business and multi-country
financial consolidations, value-added taxes, currency exchange rates, foreign
statutory reporting requirements and similar complex accounting issues.
 
COMPETITION
 
  The CRO industry consists of several hundred small, limited service
providers, several dozen medium-sized firms and several full-service CROs with
international capabilities. The Company believes that the CRO industry is
consolidating and, in recent years, several large, full-service competitors
have emerged, some of which have substantially greater technical, financial
and other resources than the Company. This trend of industry consolidation
will likely result in greater competition among the larger CROs for clients
and acquisition candidates.
 
  The large, full-service competitors of the Company include Quintiles
Transnational Corporation, PAREXEL International Corporation, Covance, Inc.,
Pharmaceutical Product Development, Inc., ClinTrials Research Inc. and IBAH,
Inc. The Company also competes against certain medium-sized CROs, especially
in Europe, as well as smaller CROs. Additionally, the Company competes against
the in house research and development departments of sponsors as well as
clinical groups affiliated with universities and teaching hospitals.
 
  The Company believes that many sponsors tend to develop preferred provider
relationships with full-service CROs, which could have the effect of excluding
other CROs from the bidding process. The Company may experience reduced access
to certain potential clients due to these arrangements. CROs compete on the
basis of several sponsor selection criteria, including reliability, past
performance, expertise and experience in specific therapeutic areas, scope of
service offerings, strengths in various geographic markets, technological
capabilities, ability to manage large-scale clinical trials both domestically
and internationally, and price.
 
CONTRACTUAL ARRANGEMENTS
   
  Most of the Company's trials management and consulting contracts are based
on preliminary cost estimates made at the start of the program, which often
are adjusted through a change order process as the study progresses. Scope
modifications are common in the CRO industry due to the nature of clinical
research, where experiences early in a program or study may lead to
alterations to the number of sites, time schedule, analysis plans or other
variables. When, during the course of performing the services as provided for
pursuant to the contract, a scope modification is identified, the Company will
begin negotiating a change in the contract value, generally on terms that are
consistent with the original contract value in relation to the change in scope
of work to be performed. Contracts generally range in duration from a few
months to several years. Generally, a portion of the contract fee is paid at
the time the study is initiated with the balance payable in monthly
installments or at milestones over the duration of the study or, in the case
of site management services, as agreed-upon units of work are performed.     
 
  Most of the Company's contracts can be terminated by the customer upon 30 to
60 days' notice under certain circumstances, including the customer's
unilateral decision to terminate the development of the product or to end a
particular study. Contracts may be terminated for a variety of other reasons,
including the failure of a product to satisfy safety requirements, unexpected
or undesired results of the product, market considerations, the customer's
decision to forego a particular study or insufficient investigator recruitment
or patient enrollment. The loss of a large contract or the loss of multiple
contracts could adversely affect the Company.
 
BACKLOG
 
  Backlog consists of anticipated net revenue from the uncompleted portion of
work from signed contracts and letters of intent. Net revenues are defined as
total professional fee income (gross revenues) less reimbursed
 
                                      37
<PAGE>
 
costs, consisting principally of investigator fees, central laboratory fees
and reimbursed travel expenses associated with field monitoring of
investigational sites. Once contracted work begins, net revenues are
recognized over the life of the contract and are booked on a percentage-of-
completion basis. In certain cases, the Company may begin work for a customer
before a contract is signed. Backlog does not include anticipated net revenues
for which the Company has begun work but for which the Company does not have a
signed letter of intent or contract, or fee-for-service contracts with no
specified dollar amount.
   
  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 variable size and duration of contracts, many of
which are performed over several years. Additionally, as noted above,
contracts generally are subject to early termination by the client or delay by
regulatory authorities for many reasons beyond the Company's control,
including unexpected test results. Moreover, the scope of a contract can
change, either positively or negatively, during the course of a study. There
can be no assurances that the Company will be able to fully realize all of its
backlog as net revenue. On September 30, 1997, the Company's backlog was
approximately $45.4 million, as compared to $29.0 million at September 30,
1996.     
 
POTENTIAL LIABILITY AND INSURANCE
 
  The Company attempts to manage the risk of liability for personal injury or
death to patients attributable to, or alleged to be attributed to, the
administration of products under study through contractual indemnification
provisions with sponsors and through insurance maintained by sponsors,
investigators and the Company. The contractual indemnifications generally do
not protect the Company against certain of its own actions, such as negligence
and willful misconduct or failure to follow the approved study protocol. The
contractual arrangements are separately negotiated with clients and the terms
and scope of such indemnification vary from client to client and from study to
study. Although most of the Company's clients are large well-capitalized
companies, the financial performance of the sponsors under these indemnities
is not secured. Therefore, the Company bears the risk that the indemnifying
party may not have the financial ability to fulfill its indemnification
obligations. 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 the sponsor or where the indemnifying party
does not fulfill its indemnification obligations. The Company currently
maintains general business liability as well as errors and omissions insurance
with respect to these risks. See "Risk Factors --Potential Liability."
 
OVERVIEW OF THE DRUG DEVELOPMENT AND APPROVAL PROCESS IN THE UNITED STATES
       
       
       
  Before a new drug is marketed, the drug must undergo extensive testing and
regulatory review in order to determine that it is safe and effective. The
development process consists of two stages: pre-clinical and clinical. The
first stage is the pre-clinical research, in which the new drug is tested in
vitro (test tube) and in animals, generally over a one to three-year period,
in order to determine the basic biological activity and safety of the drug. If
the drug is perceived to be safe for human testing, the drug then undergoes a
series of clinical tests in humans. During the clinical stage, one of the most
time-consuming and expensive parts of the drug development process, the drug
undergoes a series of tests in humans, including healthy volunteers and
patients with the targeted disease or condition.
 
  Prior to commencing human clinical trials in the United States, the sponsor
must file an Investigational New Drug ("IND") application with the FDA. In
order to receive IND status, the sponsor of the new drug must provide
available manufacturing data, pre-clinical data, information about any use of
the drug in humans in other countries or in the United States for other
purposes, and a detailed plan for the conduct of the proposed clinical trials.
The sound design of these trials, also referred to as the study protocols, is
essential to the success of the drug development effort because the protocols
must correctly anticipate the nature of the data to be generated and results
that the FDA will require before approving the drug. In the absence of any FDA
comments within 30 days after the IND filing, human clinical trials may begin.
 
                                      38
<PAGE>
 
  Although there is no statutory specification of the structure or design of
clinical trials, human trials usually start on a small scale to assess safety
and then expand to larger trials to test efficacy. These trials are usually
grouped into the following three phases, with multiple trials generally
conducted within each phase:
 
    Phase I.  Phase I trials involve testing the drug on a limited number of
  healthy individuals, typically 20 to 80 persons, to determine the drug's
  basic safety data relating to tolerance, absorption, metabolization and
  excretion as well as other pharmacological indications and actions. This
  phase lasts an average of six months to one year.
 
    Phase II.  Phase II trials involve testing a small number of volunteer
  patients, typically 100 to 200 persons who suffer from the targeted disease
  or condition, to determine the drug's effectiveness and dose response
  relationship. This phase lasts an average of one to two years.
 
    Phase III. Phase III trials involve testing large numbers of patients,
  typically several hundred to several thousand persons, to verify efficacy
  on a large scale as well as long-term safety. These trials involve numerous
  sites and generally last two to three years.
 
  After the successful completion of all three clinical phases, the sponsor of
a new drug in the United States submits a New Drug Application ("NDA") to the
FDA requesting that the product be approved for marketing. The NDA is a
comprehensive, multi-volume filing that includes, among other things, the
results of all pre-clinical and clinical studies, information about the drug's
composition and the sponsor's plans for producing, packaging and labeling the
drug. In addition, while the FDA does not use price as a criterion for
approving a new drug, advisory panels of scientists that help the FDA evaluate
new types of therapies have begun to take cost into consideration. The FDA's
review of an NDA can last from a few months, for drugs relating to life
threatening circumstances, to many years, with the average review lasting two
years. Drugs that successfully complete this review may be marketed in the
United States, subject to any conditions imposed by the FDA.
 
  As a condition to its approval of a drug, the FDA may require that a sponsor
conduct additional clinical trials following receipt of NDA approval to
monitor long-term risks and benefits, study different dosage levels, or
evaluate different safety and efficacy parameters in target patient
populations. In recent years the FDA has increased its reliance on these
trials, known as Phase IV trials, which allow new drugs that show early
promise to reach patients without the delay associated with the conventional
review process. Phase IV trials usually involve thousands of patients.
 
  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 and GCP.
 
  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 the FDA. Biological products
are regulated primarily under the Public Health Service Act, but are also
subject to regulation under the Federal Food, Drug and Cosmetic Act ("FFDCA").
 
  While some biological products may be approved for marketing via an NDA,
most manufacturers must obtain two licenses from FDA prior to marketing a
biological product: a license for the manufacturing
 
                                      39
<PAGE>
 
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 the 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.
   
 Device Development and Approval in the United States     
 
  The FFDCA and regulations thereunder require that, prior to marketing in the
United States unless exempted by regulation, all products meeting the
statutory definition of "device" receive either (depending upon the nature of
the device) FDA clearance pursuant to a premarket notification (510(k))
submission or FDA approval pursuant to a premarket approval ("PMA")
application. Generally, devices are distinguished from drugs through the
characteristics of acting or achieving their effect through means other than
pharmacological action.
 
  Human clinical trials always are 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 investigational review board ("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 IRBs 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 IRBs, but not the FDA. Such investigations nevertheless, are
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 an 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.
 
GOVERNMENT REGULATION
 
  In the United States, the Federal Food, Drug and Cosmetic Act ("FFDCA")
governs clinical trials and approval procedures, as well as the development,
manufacture, safety, labeling, storage, record keeping and
 
                                      40
<PAGE>
 
marketing of pharmaceutical products and medical services. Biological products
are subject to similar regulation under both the FFDCA and the Public Health
Service Act.
 
  The Company's business is both benefited by and subject to extensive
governmental regulation. Increased regulation leads to more complex clinical
trials and an increase in potential business for the Company. Conversely, a
relaxation in the scope of regulatory requirements, such as the introduction
of simplified marketing applications for pharmaceutical and biological
products, could decrease the business opportunities available to the Company.
 
  The Company must be diligent in its performance of work within the
directives and guidelines of regulatory agencies. A failure to comply with
applicable regulations relating to the conduct of clinical trials or the
preparation of marketing applications could lead to a variety of sanctions.
For example, regulatory violations in the United States could result,
depending on the nature of the violation and the type of product involved, in
the issuance of a Warning Letter, termination of a clinical study, refusal of
the FDA or the EMEA to approve clinical trial or marketing applications or
withdrawal of such applications, injunction, seizure of investigational
products, civil penalties, criminal prosecutions, or debarment of the Company
from assisting in the submission of new drug applications.
 
  The Company monitors its clinical trials to test for compliance with
government regulations. The Company has adopted standard operating procedures
that are designed to satisfy regulatory requirements and serve as a mechanism
for controlling and enhancing the quality of its clinical trials. The
Company's procedures are written in accordance with the regulations and
guidelines appropriate to the region where they will be used, thus ensuring
compliance with GCP guidelines. In North America, FDA regulations and
guidelines serve as a basis for the Company's procedures. Within Europe, all
work is carried out in accordance with the European Community Note for
Guidance, "Good Clinical Practice for Trials on Medicinal Products in the
European Community." In order to facilitate international clinical trials, the
Company has implemented common standard operating procedures across all of its
regions to assure consistency whenever it is feasible and appropriate to do
so.
 
  The industry standard for the conduct of clinical research and development
studies is embodied in the regulations for GCP. Although GCP has not been
formally adopted by the FDA nor, with certain exceptions, by similar
regulatory authorities in other countries, certain provisions of GCP have been
included in FDA regulations. As a matter of practice, the FDA and many other
regulatory authorities require that test results submitted to such authorities
be based on studies conducted in accordance with GCP. These regulations
include (i) complying with FDA regulations governing the selection of
qualified investigators; (ii) obtaining specific written commitments from the
investigators; (iii) verifying that patient informed consent is obtained; (iv)
monitoring the validity and accuracy of data; (v) verifying drug or device
accountability; and (vi) instructing investigators to maintain records and
reports. The Company also must maintain reports for each study for specified
periods for inspection by the study sponsor and the FDA during audits.
 
INTELLECTUAL PROPERTY
 
  The Company has developed certain computer software, business models,
management methodologies and standard operating procedures that are intended
to maximize the quality and efficiency of its services. Although the Company
does not believe that its intellectual property rights are as important to its
operating results as are such factors as the technical expertise, knowledge,
ability and experience of its professional staff, the Company believes that
its technological capabilities can provide significant benefits to its clients
and often can provide a competitive advantage. Therefore, each employee, as a
condition of employment, signs a confidentiality agreement designed to help
protect the Company's intellectual property and senior management have signed
non-compete agreements.
 
EMPLOYEES
   
  At September 30, 1997, the Company had 614 employees, approximately 54 of
whom hold Ph.D., M.D. or Pharm.D. degrees and approximately 74 of whom hold
other master's or other post-graduate degrees. None of     
 
                                      41
<PAGE>
 
the Company's employees is represented by a collective bargaining agreement,
nor has the Company experienced work stoppages. The Company believes that its
relations with its employees are good.
 
  The Company's performance depends on its ability to attract and retain
qualified professional, scientific and technical staff at reasonable cost. The
level of competition among employers for such skilled personnel is high. The
Company believes that its salary scales, employee benefits plans and
employment policies enhance employee morale, professional commitment and work
productivity and provide an incentive for employees to remain with the
Company. A significant majority of its employees at the manager level and
higher have been awarded stock options as a long term incentive.
 
FACILITIES
   
  The Company leases all of its facilities. It now has under lease
approximately 280,650 square feet at the following locations: Vienna and
Charlottesville, VA; Mannheim, Germany; Lenexa, Prairie Village and Overland
Park, KS; Swansea, Wales; Red Bank, NJ; San Francisco, CA; and Atlanta, GA.
       
  In November 1997, the Company and the University of Virginia Real Estate
Foundation entered into a lease of a four-story building comprising
approximately 76,000 square feet for the Company's Charlottesville, VA
operations. The lease has a fifteen-year term, renewable for up to two
additional five-year terms, with a base rental rate of $19.95 per square foot
for the first five years. The Company's occupancy of the building, which has
yet to be constructed, is scheduled to occur in the first quarter of 1999.
Upon the Company's occupancy of this building, the University of Virginia Real
Estate Foundation has agreed to assume the principal existing real estate
lease of the Company in Charlottesville.     
 
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.

    of 5% and 10% over the term of the options, as required by the rules of
    the Securities and Exchange Commission. Actual gains, if any, on stock
    option exercises are dependent on future performance of the Common Stock.

    in this table will be realized.

  Earle Martin, James Powers and Patrick Donnelly each entered into an
employment agreement with Associates on October 11, 1996, October 11, 1996 and
October 16, 1996, respectively. These employment agreements, which expire on
November 1, 1998 but provide for automatic renewal for successive one-year
terms unless either party thereto elects not to renew at least 90 days before
the expiration of the current term, provide for an annual base salary of

  In April 1997, Robert J. Dockhorn, M.D. entered into an Employment Agreement
with IMTCI. This Employment Agreement has an initial three-year term but is
subject to renewal for successive one-year terms upon the delivery by either
party of a renewal request at least 90 days prior to the end of the current
term, so long as the request is not declined by the other party within such
90-day period. This Agreement also provides for an annual salary of $175,000,
subject to increases approved by the Compensation Committee, as well as cash
bonuses and stock options as may be approved by the Compensation Committee.
 
  In October 1997, Dr. Judith Ann Hemberger entered into a Consulting
Agreement with Associates. Pursuant to the agreement, Dr. Hemberger is to
perform consulting services on an as needed basis at rates between $1,000 and
$2,000 per day, as determined on a case-by-case basis. The agreement is
terminable by either party upon thirty days' notice.
 
STOCK INCENTIVE PLANS
   
  Prior to July 1997, the Company awarded stock options to certain directors,
employees and consultants under the terms of the Pharmaceutical Research
Associates, Inc. Stock Option Plan, which was adopted and assumed by the
Company in October 1996 in connection with its recapitalization and
reorganization and amended and restated in September 1997 (as so amended and
restated, the "1993 Plan"). As part of that recapitalization and
reorganization, existing 1993 Plan options to purchase shares of Class B
Common Stock of Associates were exchanged on a one-to-one basis for options to
purchase shares of Common Stock. Options to purchase an aggregate of 1,538,179
shares of Common Stock were outstanding as of September 30, 1997 under the
1993 Plan at exercise prices ranging from $0.09 to $13.96 per share. The
Company does not intend to make any additional option awards under the 1993
Plan.     
   
  In July 1997 the Board of Directors adopted the PRA International, Inc. 1997
Stock Option Plan and reserved for issuance thereunder an aggregate of 197,000
shares of Common Stock (as amended and restated in September 1997, the "1997
Plan" and, collectively with the 1993 Plan, the "Plans"). Options to purchase
an aggregate of 58,509 shares of Common Stock at an exercise price of $13.96
per share were outstanding as of September 30, 1997 under the 1997 Plan.     
 
  The purpose of the 1993 Plan was, and the purpose of the 1997 Plan is, to
provide directors, key employees and certain advisors with additional
incentives by increasing their proprietary interest in the Company.
 
  The 1993 Plan provided and the 1997 Plan provides for the grant of incentive
stock options ("ISOs") as defined in Section 422 of the Internal Revenue Code
of 1986, as amended (the "Code"), nonqualified stock options and restricted
stock (collectively "Awards"). The 1997 Plan will be administered by the full
Board of Directors of the Company or, at the discretion of the Board, the
Compensation Committee provided that it is comprised solely of two or more
nonemployee directors who are "disinterested" within the meaning of Rule 16b-3
(the full Board or the Compensation Committee, as applicable, the
"Committee"). Subject to the terms of the 1997 Plan, the Committee has the
sole authority to grant Awards under the 1997 Plan, to construe and interpret
the 1997 Plan and to make all other determinations and take any and all
actions necessary or advisable for the administration of the 1997 Plan.
Similarly, the Committee has the authority to administer, interpret and
construe and carry out the 1993 Plan.
   
  In October 1996, the Company granted to Patrick K. Donnelly options to
purchase 118,200 shares of Common Stock at an exercise price of $2.92 per
share that was less than the then fair market value of the Common Stock. These
unqualified options were granted outside of the 1993 Plan in connection with
Mr. Donnelly's past service as a Director of the Company and commencement of
employment with the Company.     
 
  All of the Company's employees and consultants and its subsidiaries are
eligible to receive Awards under the 1997 Plan, but only employees of the
Company are eligible to receive ISOs. In addition, the 1997 Plan provides for
automatic grants to unaffiliated outside Directors of options to purchase
5,000 shares of Common Stock upon initial election as a Director and options
to purchase 1,000 shares of Common Stock on each anniversary thereafter that
he or she continues to serve as a Director. Options will be exercisable during
the period specified in each stockholder's or option agreement and will
generally be exercisable in installments
 
                                      51
<PAGE>
 
   
pursuant to a vesting schedule to be determined by the Committee or the Board,
as applicable. Notwithstanding the provisions of any stockholder's or option
agreement, options issued pursuant to each of the Plans shall become
immediately exercisable in the event of a "change of control" as therein
defined and may, in the discretion of the Committee, become immediately
exercisable for any or no reason. In addition, the Company has the right,
exercisable in its discretion, to vest certain options in the event of an
extraordinary event relating to the Company, including, without limitation, a
corporate acquisition or merger, a sale of all or substantially all of the
stock of the Company or an asset or private stock sale. No option will remain
exercisable later than ten years after the date of grant (or five years from
the date of grant in the case of ISOs granted to holders of more than 10% of
the Common Stock).     
 
  The exercise price for ISOs granted under either of the Plans may be no less
than the fair market value of the Common Stock on the date of grant (or, in
the case of the 1993 Plan, 110% in the case of ISOs granted to employees
owning more than 10% of the Common Stock). The exercise price for nonqualified
options and all other Awards granted under the 1997 Plan will be in the
discretion of the Committee.
 
  The Code provides special rules for the income tax treatment of ISOs. Except
as noted below, no taxable income results to a holder of options granted
pursuant to the 1993 Plan or the 1997 Plan (an "Optionholder") either upon the
grant of an ISO or upon the issuance of shares to the Optionholder upon
exercise of the option. Instead, on a disposition of the shares of Common
Stock acquired, provided such disposition is not a "disqualifying disposition"
as defined below, the difference between the amount realized on disposition
and the amount paid for the shares of Common Stock will be treated for tax
purposes as gain or loss from the disposition of a capital asset. In general,
a "disqualifying disposition" is a disposition within two years from the date
the option was granted or within one year after the transfer of the shares to
the Optionholder following exercise of the ISO. A disqualifying disposition
does not, however, include a transfer of the shares received upon exercise of
an ISO by an insolvent individual to a trustee or other fiduciary pursuant to
the requirements of, or as allowed by the United States bankruptcy code. In
the event of a disqualifying disposition, both ordinary income and capital
gain or loss may be recognized by the Optionholder. Specifically, on a
disqualifying disposition ordinary income must be recognized by the
Optionholder in an amount equal to (i) the lower of the fair market value of
the shares at the time of exercise and the price at which such shares were
sold, less (ii) the exercise price paid for the shares. In addition, on a
disqualifying disposition capital gain or loss may be recognized in the amount
of the difference between the amount realized and the basis of the shares
(which basis will first be increased by the amount of ordinary income
recognized on the disqualifying disposition). Although the exercise of an ISO
will not generally result in taxable income, any income an Optionholder would
have been required to recognize had the option been a nonqualified stock
option will be includable in the Optionholder's income for purposes of the
alternative minimum tax.
 
  Because nonqualified stock options are considered to have no readily
ascertainable fair market value under applicable Treasury regulations, no
taxable income will be recognized by an Optionholder upon the grant of such an
option. The Optionholder will instead recognize ordinary income on the date of
exercise in an amount equal to the excess of the fair market value of the
shares on the date of exercise over the amount paid for the shares. The basis
of the shares for purposes of determining the amount of capital gain or loss
to be recognized on any subsequent taxable disposition of the shares will then
include both the amount paid for the shares and the amount of ordinary income
recognized in connection with the exercise of the option (i.e., the fair
market value of the shares on the date of exercise of the option).
 
  The Company will be entitled to a deduction in connection with an ISO or a
nonqualified stock option only in the event and to the extent ordinary income
is recognized by the Optionholder. Any such deduction will be allowed to the
Company for its taxable year with which or in which ends the taxable year of
the Optionholder in which the Optionholder's recognition of ordinary income
occurs.
   
  As of September 30, 1997, the option holders have outstanding options to
purchase up to 1,596,689 shares of Common Stock granted under the Plans and
the Company has reserved 138,491 shares of Common Stock for future issuance
under its 1997 Plan. The Company intends to register the shares issuable upon
exercise of options granted under the Plans and, upon such registration, the
shares will be eligible for resale in the public market. See "Shares Eligible
for Future Sale."

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  The Compensation Committee is responsible for determining salaries,
incentives and all other forms of compensation for directors and officers of
the Company. The Compensation Committee also administers various incentive
compensation and benefit plans, including the Plans. The members of the
Compensation Committee of the Board of Directors are Messrs. Martin, Penner,
Dupree and Dr. Hemberger, with Mr. Martin being the only member who is an
employee of the Company and Dr. Hemberger being the only member who is a
consultant of the Company. See "--Committees of the Board of Directors," and

                             CERTAIN TRANSACTIONS
   
  In November 1994, pursuant to a $1,000,000 venture capital financing with
Virginia Capital, L.P. ("Virginia Capital"), successor in interest to Vedcorp,
L.C., Associates issued (i) a 12.5% subordinated debenture originally due
December 31, 1998 in the original principal amount of $750,000, (ii) a warrant
to purchase shares of Class C Common Stock of Associates constituting 6.67% of
the common stock of Associates on a fully-diluted basis for an aggregate
exercise price of $500,000 and (iii) 53,512 shares of Class E Preferred Stock
of Associates. In August 1997, the debenture was repaid in full and the
warrant, as subsequently modified, was exercised in part for 236,136 shares of
Common Stock.     
 
  In August 1995, pursuant to a venture capital financing with Sirrom
Investments, Inc. ("Sirrom"), successor in interest to Sirrom Capital
Corporation, Associates issued (i) a secured promissory note in the original
principal amount of $2 million due August 10, 2000, which is secured by a
subordinated blanket lien on Associates' assets and (ii) a stock purchase
warrant exercisable for shares of Class C Common Stock of Associates
constituting 6% of the common stock of Associates on a fully-diluted basis for
an aggregate exercise price of $.01 per share, which, as subsequently
modified, was exercised in full in April, 1997. In connection with this
transaction, Virginia Capital's warrant was replaced by a warrant to purchase
shares of Class C Common Stock of Associates constituting 12.27% of the common
stock of Associates on a fully-diluted basis for an aggregate exercise price
of $500,000.
   
  On February 7, 1996, Associates made a personal loan to Associates' founder,
Raymond J. Rugloski, in the amount of $500,000. This loan was financed from
the proceeds of its sale in December 1995/January 1996 of 76,830 shares of
Class F Preferred Stock of Associates at a price per share of $6.5080,
representing, in the event of their conversion into common stock of
Associates, 4% of the common stock of Associates on a fully-diluted basis, to
Virginia Capital, Sirrom and Messrs. Earle Martin, James Powers, Joachim
Vollmar and W. Bain MacLachlan. Mr. Rugloski repaid this loan in full in
October 1996.     
 
  In September 1996, as a result of anti-dilution protections afforded Raymond
Rugloski and his wife, Carolyn Rugloski, Sheridan Snyder, Virginia Capital,
Sirrom and the other Class F Preferred Stockholders of Associates, 44,925
shares of Class A Common Stock were issued to the Rugloskis, 4,992 additional
shares of Class B Common Stock were issued to Mr. Snyder, the amount of shares
of Class C Common Stock of Associates for which Virginia Capital's and
Sirrom's warrants were exercisable was increased by 9,479 and 3,792 shares,
respectively, and the Class F Preferred Stockholders of Associates received an
additional 5,482 shares of Class F Preferred Stock.
 
  (All of the foregoing references to the share numbers of capital stock of
Associates are on an as-issued basis and do not reflect the effect of the
stock split on the shares of Common Stock received in respect thereof pursuant
to the agreement and plan of share exchange referred to below.)
 
  In October 1996, the Company completed a recapitalization and
reorganization. First, the Company became the holding company of Associates,
pursuant to an agreement and plan of share exchange between the Company and
Associates. Under the agreement and plan of share exchange, all outstanding
shares and all options and warrants to purchase shares of each class of common
and preferred stock of Associates were acquired by the Company in exchange for
an identical number of outstanding shares and options and warrants to purchase
shares of Common Stock. The Company then sold, for an aggregate purchase price
of approximately $19.1 million, 1,631,548 shares of its Series A Preferred
Stock to certain affiliates of The Carlyle Group, along with a related warrant
agreement providing for the issuance of warrants to purchase an identical
number of shares of Common Stock upon the occurrence of certain circumstances.
A portion of this issuance was immediately transferred to an entity unrelated
to Carlyle. In November 1996, Virginia Capital purchased 26,534 shares of
Series A Preferred Stock and a related warrant agreement for an aggregate
purchase price of approximately $310,000. (Simultaneously with the closing of
the Offering, these shares of Series A Preferred Stock will convert into
shares of Common Stock at the same ratio as the Common Stock stock split being
effected prior to the closing of the Offering and the warrant agreements, as
well as certain other rights and interests, will terminate in their entirety.)
 
                                      54
<PAGE>
 
The Company used approximately $9.2 million of the proceeds from the sale of
the Series A Preferred Stock to purchase certain shares of, or options for,
Common Stock, including approximately $7.0 million to purchase shares from
Raymond Rugloski and certain of his family members. Daniel A. D'Aniello, David
W. Dupree and Peter M. Manos, each a Director of the Company, are a Managing
Director, a Managing Director and a Vice President, respectively, of The
Carlyle Group.
 
  In April 1997, the Company acquired the capital stock of IMTCI, a CRO with a
trials management and clinical research center in Lenexa, Kansas and three
investigational sites in Kansas, from the following selling stockholders: Dr.
Robert J. Dockhorn, an executive officer of IMTCI; Dr. Dockhorn's wife,
Beverly W. Dockhorn; Dr. Dockhorn's sons, each of whom is an officer of
Associates, Douglas R. Dockhorn and David W. Dockhorn, jointly with their
respective wives and, in the case of Douglas R. Dockhorn, individually; and
the Robert and Beverly Dockhorn Charitable Remainder Unitrust. Of the
aggregate purchase price of approximately $15.3 million paid to IMTCI's
stockholders, $8 million was paid in the form of cash, $5.3 million was paid
in the form of notes and $2 million was paid in the form of shares of Common
Stock. Following the acquisition of the IMTCI shares by the Company, IMTCI
transferred to Associates certain assets not essential to IMTCI's clinical
site activities.
 
  In May 1997, the Company, through IMTCI, acquired the capital stock of
Crucible, a site management organization with a clinical research center and
investigational sites in Atlanta, another investigational site in Savannah,
Georgia and an investigational affiliation in San Juan, Puerto Rico. Stephen
F. Gordon, M.D. and Kathleen A. Oettinger, who continue to be officers and
directors of Crucible, owned 52% and 24%, respectively, of the outstanding
capital stock of Crucible, with the remainder of the capital stock being owned
by Ms. Oettinger's husband, Roy H. Autry, Ph.D. The aggregate purchase price
of approximately $300,000 was paid to the sellers in cash. At the time of the
closing of the Crucible acquisition, Dr. Gordon and Ms. Oettinger had received
loans from Crucible in the aggregate amount of approximately $247,000. In the
event that Crucible meets certain net revenue thresholds during 1997 and 1998,
these two individuals are entitled to receive bonuses, to be applied solely to
the repayment of such loans, up to an aggregate amount equal to the amount of
these loans. Any amounts outstanding after the 1998 bonus calculation are be
to repaid in five equal annual installments commencing on December 31, 1999
and the repayment of such loans is secured by all stock options granted to
such individuals from time to time and any Common Stock received by them in
connection with any exercise thereof.
   
  The Company leases its facilities in Lenexa, Kansas from Dockhorn
Properties, L.L.C., a Kansas limited liability company owned by Robert J.
Dockhorn, Trustee of the Robert J. Dockhorn Revocable Trust dated January 5,
1984, as amended, who individually is an officer of IMTCI, and Douglas R.
Dockhorn and David W. Dockhorn, who both are officers of the Associates. The
Company expects to make annualized payments of approximately $1.3 million
under this lease. The Company's Prairie Village, Kansas facilities are leased
from Beverly W. Dockhorn, Trustee of the Beverly W. Dockhorn Revocable Trust
dated January 5, 1984, as amended, who individually is the wife of Robert J.
Dockhorn. The Company expects to make annualized payments of approximately
$128,012 under such lease. The Company has been advised by its real estate
advisor that both of these leases provide rents and other terms and conditions
that are commercially reasonable in the markets involved.     
 
  The Company believes that the terms of all of the above transactions are as
favorable to the Company as would have been obtained through arms-length
negotiations with unrelated parties.
 
RELATED-PARTY TRANSACTIONS POLICY
 
  The Company has adopted a policy that all future transactions between the
Company and its officers, directors and affiliates must be on terms no less
favorable to the Company than those that could be obtained from unrelated
third parties, and must be approved by a majority of the disinterested members
of the Company's Board of Directors.

                         DESCRIPTION OF CAPITAL STOCK
 
  Effective as of the closing of the Offering, the authorized capital stock of
the Company will consist of 25,000,000 shares of Common Stock, par value $.01
per share, and 5,000,000 shares of Preferred Stock, par value $.01 per share.
 
COMMON STOCK
   
  As of September 30, 1997, there were 1,736,632 shares of Common Stock and
1,658,082 shares of Series A Preferred Stock outstanding. Upon the completion
of the closing of the Offering, there will be 7,753,053 shares of Common Stock
outstanding (assuming no exercise of the Underwriters' over-allotment option),
after giving effect to the conversion of the outstanding shares of Series A
Preferred Stock into Common Stock and the sale of the shares of Common Stock
being offered in the Offering. The holders of shares of Common Stock are
entitled to one vote per share held on all matters submitted to a vote of
stockholders of the Company and do not have cumulative voting rights.
Accordingly, holders of a majority of the shares of the Common Stock entitled
to vote in any election of directors may elect all of the directors standing
for election, and, after the Offering, the current stockholders and directors
and officers of the Company will be able to elect all of the directors. In
addition, holders of the Common Stock are entitled to receive ratably such
dividends, if any, as may be declared from time to time by the Board of
Directors out of funds legally available therefor. See "Dividend Policy." In
the event of the dissolution, liquidation or winding up of the Company, the
holders of Common Stock are entitled to share ratably in all assets remaining
after payment of all liabilities of the Company. Dividend and liquidation
rights attributable to the Common Stock would be subject to any preferential
rights associated with any outstanding Preferred Stock. Holders of Common
Stock have no preemptive, subscription, redemption or conversion rights. All
outstanding shares of Common Stock are, and the shares of Common Stock offered
by the Company in the Offering will be, when issued, fully paid and
nonassessable.     
 
WARRANTS
 
  As of September 30, 1997, there is one outstanding warrant held by Virginia
Capital, L.P. and exercisable for up to 236,136 shares of Common Stock. This
warrant has an expiration date of November 14, 2001 and has an exercise price
of $1.06 per share. Virginia Capital is entitled to certain registration
rights in respect of the shares of Common Stock issuable upon exercise of its
warrant. See "Registration Rights."
 
PREFERRED STOCK
 
  After giving effect to the conversion of the Series A Preferred Stock (which
will occur simultaneously with the closing of the Offering), there will be no
shares of Preferred Stock outstanding. The Board of Directors has the
authority to issue Preferred Stock in one or more series, and, to the fullest
extent permitted by law, to fix the rights, preferences, privileges and
restrictions, including dividend, conversion, voting, redemption (including
sinking fund provisions), and other rights, liquidation preferences and the
number of shares constituting any series and the designations of such series,
without any further vote or action by the stockholders of the Company. The
rights and preferences of the Preferred Stock may be senior to the rights and
preferences of the Common Stock. Because the terms of the Preferred Stock may
be fixed by the Board of Directors of the Company without stockholder action,
the Preferred Stock could be issued quickly, with terms calculated to defeat a
proposed takeover of the Company, or to make the removal of the management of
the Company more difficult. Under certain circumstances, this could have the
effect of decreasing the market price of the Common Stock.
 
REGISTRATION RIGHTS
 
  Pursuant to the terms of the Stockholders' Agreement entered into by certain
of the Company's stockholders and the Company in connection with the Company's
sale of Series A Preferred Stock to certain affiliates of The Carlyle Group,
the Company granted to those affiliate purchasers the right on two occasions,
and memorialized the rights of each of Virginia Capital and Sirrom on one
occasion, to require, at any time after the closing of a
 
                                      57
<PAGE>
 
registration for the Company's initial public offering, that the Company
register under the Securities Act shares of Common Stock held by them or to be
held by them upon the exercise of certain conversion rights or outstanding
warrants, provided that, in each such case, such offering must reasonably be
predicted to effect the registration of an aggregate gross amount of the
Company's Common Stock having a value of at least $25 million, including
shares of Common Stock requested to be registered pursuant to the following
paragraph.
 
  These securityholders also have a "piggyback" right to have their shares of
Common Stock included in any registration by the Company initiated on its own
behalf or on behalf of its other stockholders other than a registration for
the Company's initial public offering. Messrs. Martin, Powers, Vollmar and
MacLachlan also have such a piggyback right as to an aggregate of 38,915
shares. Such piggyback registration rights are subject to the right of the
managing underwriters of an underwritten offering to limit the number of such
stockholders' shares to be included in such offering.
 
  The Company will bear the expenses of all such registrations, other than the
legal fees of participating stockholders and the underwriters' fees, discounts
or commissions relating to their Common Stock being registered.
 
  The former IMTCI stockholders also were granted piggyback registration
rights in any subsequent public offering by the Company with respect to the
143,272 shares of Common Stock received by them as partial payment by the
Company for the capital stock of IMTCI pursuant to the terms of the related
stock purchase agreement.
 
  In October 1997, all of the foregoing registration rights were consolidated
into a single Registration Rights Agreement.
 
DELAWARE LAW AND CERTAIN CHARTER AND BY-LAW PROVISIONS
 
  The Company is subject to the provisions of Section 203 of the General
Corporation Law of Delaware. In general, Section 203 prohibits a publicly-held
Delaware corporation from engaging in a "business combination" with an
"interested stockholder" for a period of three years after the date of the
transaction in which the person became an interested stockholder, unless the
business combination is approved in a prescribed manner. A "business
combination" includes mergers, asset sales and other transactions resulting in
a financial benefit to the interested stockholder. Subject to certain
exceptions, an "interested stockholder" is a person who, together with
affiliates and associates, owns, or within three years did own, 15% or more of
the corporation's voting stock.
 
  The Restated Certificate of Incorporation and Amended and Restated By-Laws
(the "By-Laws") provide that, effective upon the consummation of the Offering,
any action required or permitted to be taken by the stockholders of the
Company may be taken only at duly called annual or special meetings of the
stockholders, and that special meetings may be called only by the Chairman of
the Board of Directors, the President or a majority of the Board of Directors
of the Company. These provisions could have the effect of delaying until the
next annual stockholders' meeting stockholder actions that are favored by the
holders of a majority of the outstanding voting securities of the Company,
including actions to remove directors. These provisions also may discourage
another person or entity from making a tender offer for the Common Stock,
because such person or entity, even if it acquired all or a majority of the
outstanding voting securities of the Company, would be able to take action as
a stockholder (such as electing new directors or approving a merger) only at a
duly called stockholders meeting, and not by written consent.
 
  The Company's Restated Certificate of Incorporation and By-Laws provide
that, effective upon the consummation of the Offering, for nominations for the
Board of Directors or for other business to be properly brought by a
stockholder before a meeting of stockholders, the stockholder must first have
given timely notice thereof in writing to the Secretary of the Company. To be
timely, a notice of nominations or other business to be brought before a
stockholders meeting must be delivered not less than 50 days prior to such
stockholders meeting, provided that in the event that less that 55 days'
notice or prior public disclosure of the date of the
 
                                      58
<PAGE>
 
meeting is given or made to stockholders, a notice of nominations or other
business to be brought before such stockholders meeting must be delivered
within seven days following the day on which such notice of the date of the
stockholders meeting was given or such public disclosure was made. The notice
must contain, among other things, certain information about the stockholder
delivering the notice and, as applicable, background information about each
nominee or a description of the proposed business to be brought before the
meeting.
 
  The Company's Restated Certificate of Incorporation and By-Laws provide for
the division of the Board of Directors into three classes, as nearly equal in
size as possible, with staggered three-year terms. See "Management--Executive
Officers, Key Employees and Directors." A director may be removed only for
cause and then only by the vote of the majority of the shares entitled to vote
for the election of directors.
 
  The Company's Restated Certificate of Incorporation empowers the Board of
Directors, when considering a tender offer or merger or acquisition proposal,
to take into account factors in addition to potential short-term economic
benefit to stockholders. Such factors may include (i) comparison of the
proposed consideration to be received by stockholders in relation to the then
current market price of the Company's capital stock, the estimated current
value of the Company in a freely negotiated transaction and the estimated
future value of the Company as an independent entity, and (ii) the impact of
such a transaction on the employees, suppliers and customers of the Company
and its effect on the communities in which the Company operates.
 
  The General Corporation Law of Delaware provides generally that the
affirmative vote of a majority of the shares entitled to vote on any matter is
required to amend a corporation's certificate of incorporation or by-laws,
unless the corporation's certificate of incorporation or by-laws, as the case
may be, requires a greater percentage. The Company's Restated Certificate of
Incorporation requires the affirmative vote of at least two-thirds of the
outstanding voting stock of the Company to amend or repeal any of the
foregoing provisions, the aforementioned provisions relating to the ability of
the Board of Directors to issue shares of Preferred Stock or to reduce the
number of authorized shares of Common Stock or Preferred Stock. A two-thirds
vote also is required to amend or repeal any of the foregoing By-Law
provisions. Such two-thirds stockholders vote would in either case be in
addition to any separate class vote that might, in the future, be required
pursuant to the terms of any Preferred Stock that might be outstanding at the
time any such amendments are submitted to stockholders. The By-Laws also may
be amended or repealed by a majority vote of the Board of Directors.
 
  The Company's Restated Certificate of Incorporation contains certain
provisions permitted under the General Corporation Law of Delaware relating to
the liability of directors. The provisions eliminate a director's liability
for monetary damages for a breach of fiduciary duty, except in certain
circumstances involving wrongful acts, such as the breach of a director's duty
of loyalty or acts or omissions which involve intentional misconduct or a
knowing violation of law. The General Corporation Law of Delaware also
authorizes the Company to indemnify its directors and officers and the
Company's Restated Certificate of Incorporation does to the fullest extent
provided by law. The Company believes that these provisions will assist the
Company in attracting and retaining qualified individuals to serve as
directors.
 
TRANSFER AGENT AND REGISTRAR
 
  The transfer agent and registrar for the Common Stock is BankBoston, N.A.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Upon completion of the Offering, the Company will have a total of 7,753,053
shares of Common Stock outstanding (8,165,553 shares if the Underwriters'
over-allotment options are exercised in full). Of these shares, the 2,750,000
shares of Common Stock offered hereby (3,162,500 shares if the Underwriters'
over-allotment options are exercised in full) will be freely tradable without
restriction or registration under the Securities Act by persons other than
"affiliates" of the Company, as defined under the Securities Act. The
remaining 5,003,053 shares of Common Stock outstanding and the 1,414,084
shares of Common Stock issuable upon exercise of outstanding options and
warrants beginning 90 days after the Offering (collectively, the "Restricted
Shares") are or will be issued and sold by the Company in private transactions
in reliance upon one or more exemptions contained in the Securities Act.
Subject to their agreement with the Underwriters described below, the holders
of Restricted Shares may, in certain circumstances, be eligible to sell such
shares in the public market pursuant to Rule 144 or Rule 701 promulgated under
the Securities Act ("Rule 701").
 
  In general, under Rule 144, as currently in effect, a person (or persons
whose shares are aggregated) that has beneficially owned Restricted Shares for
at least one year, including persons that may be deemed "affiliates" of the
Company, would be entitled to sell within any three-month period a number of
shares that does not exceed the greater of one percent of the number of shares
of Common Stock then outstanding (approximately 77,531 shares upon completion
of the Offering) or the average weekly trading volume of the Common Stock
during the four calendar weeks preceding the filing of a Form 144 with respect
to such sale. Sales under Rule 144 also are subject to certain manner of sale
provisions and notice requirements, and to the availability of current public
information about the Company. In addition, a person that is not deemed to
have been an affiliate of the Company at any time during the 90 days preceding
a sale, and that has beneficially owned the shares proposed to be sold for at
least two years, would be entitled to sell such shares under Rule 144(k)
without regard to the requirements described above. In addition, at any time
after 90 days following the effective date of this Prospectus, shares issued
in compliance with Rule 701 and which are otherwise transferable in accordance
with the terms of any restrictive agreements with the Company relating thereto
may be sold without regard to the holding period referred to above, as
described below.
   
  Subject to certain limitations on the aggregate offering price of securities
offered and sold in reliance on Rule 701 and certain other conditions, Rule
701 may be relied upon with respect to the resale of shares of Common Stock
originally purchased from the Company by its employees, directors, officers,
consultants and advisors between May 20, 1988 (the effective date of Rule 701)
and the date the Company becomes subject to the reporting requirements of the
Securities Exchange Act of 1934, as amended (the "Exchange Act") pursuant to
written compensatory benefit plans or written contracts relating to the
compensation of such persons. In addition, Rule 701 will apply to typical
stock options granted by an issuer before it becomes subject to the reporting
requirements of the Exchange Act (including options granted before May 20,
1988 and exercises thereof after the date of this Prospectus). Shares of
Common Stock issued in reliance on Rule 701 are "Restricted Shares" and,
beginning 90 days after the date of this Prospectus, may be sold by
affiliates, subject to the provisions described above regarding manner of
sale, notice requirements, volume limitations and the availability of current
public information under Rule 144, but without compliance with its one-year
minimum holding period requirement, and by persons other than affiliates,
subject only to the provisions regarding manner of sale under Rule 144.     
 
  Under Rule 144 (and subject to the conditions thereof), approximately
4,446,345 Restricted Shares will become eligible for sale upon completion of
the Offering, of which 4,446,345 are subject to lockup restrictions as
described below, and under Rule 701 (and subject to the conditions thereof),
approximately 1,355,248 additional Restricted Shares will become eligible for
sale 90 days after the Offering, of which 1,345,248 shares are subject to
lockup restrictions as described below. The Company, its officers and
directors, and certain other stockholders of the Company (who in the aggregate
will hold 6,407,137 Restricted Shares upon completion of the Offering) have
agreed that they will not directly or indirectly, offer, sell, offer to sell,
grant any option to purchase or otherwise sell or dispose (or announce any
offer, sale, offer of sale, grant of any options to purchase or sale or
disposition) of any shares of Common Stock or other capital stock of the
Company, or any securities convertible
 
                                      60
<PAGE>
 
into, or exercisable, or exchangeable for, any shares of Common Stock or other
capital stock of the Company without the prior written consent of the
Underwriters' Representatives, for a period of 180 days from the date of this
Prospectus, except, in some cases, certain transfers to affiliated parties are
permitted. In addition, certain holders of the Common Stock may require the
Company to register their shares of Common Stock under the Securities Act,
which would permit such holders to resell a certain amount of their shares
without complying with Rule 144. See "Description of Capital Stock--
Registration Rights." Registration and sale of such shares could have an
adverse effect on the trading price of the Common Stock.
 
  Prior to the Offering, there has been no public market for the Common Stock
of the Company and no predictions can be made of the effect, if any, that the
sale or availability for sale of shares of additional Common Stock will have
on the market price of the Common Stock. Nevertheless, sales of substantial
amounts of Common Stock in the public market or the perception that such sales
could occur could adversely affect the market price of Common Stock and could
impair the Company's future ability to raise capital through an offering of
its equity securities. See "Risk Factors--Effect of Outstanding Shares on
Market" and "Description of Capital Stock--Registration Rights."

  The Underwriting Agreement provides that the obligations of the several
Underwriters to pay for and accept delivery of the shares are subject to
approval of certain legal matters by counsel and to certain other conditions.
The Underwriters are obligated to take and pay for all shares of Common Stock
offered hereby (other than those covered by the over-allotment option
described below) if any such shares are taken.
 
  The Underwriters, for whom Smith Barney Inc., NationsBanc Montgomery
Securities, Inc. and Wessels, Arnold and Henderson, L.L.C. are acting as
representatives (the "Representatives"), propose to offer part of the shares
of Common Stock directly to the public at the public offering price set forth
on the cover page of this Prospectus and part of the shares to certain dealers
at a price which represents a concession not in excess of $   per share under
the public offering price. The Underwriters may allow, and such dealers may
reallow, a concession not in excess of $   per share to other Underwriters or
to certain other dealers. After the initial offering of the shares to the
public, the public offering price and such concessions may be changed by the
Representatives. The Representatives of the Underwriters have advised the
Company that the Underwriters do not intend to confirm sales to accounts over
which they exercise discretionary authority.
 
  The Company has granted to the Underwriters an option, exercisable for 30
days from the date of this Prospectus, to purchase up to an aggregate of
412,500 additional shares of Common Stock at the price to the public set forth
on the cover page of this Prospectus, minus the underwriting discounts and
commissions. The Underwriters may exercise such option solely for the purpose
of covering over-allotments, if any, in connection with the sale of the shares
offered hereby. To the extent such option is exercised, each Underwriter will
become obligated, subject to certain conditions, to purchase approximately the
same percentage of such additional shares as the number of shares set forth
next to such Underwriter's name in the preceding table bears to the total
number of shares in such table.
 
  In connection with this Offering and in compliance with applicable law, the
Underwriters may overallot (i.e., sell more Common Stock than the total amount
shown on the list of Underwriters and participations which appears above) and
may effect transactions which stabilize, maintain or otherwise affect the
market price of the Common Stock at levels above those which might otherwise
prevail in the open market. Such transactions may include placing bids for the
Common Stock or effecting purchases of the Common Stock for the purpose of
pegging, fixing or maintaining the price of the Common Stock or for the
purpose of reducing a snydicate short position created in connection with the
Offering. A syndicate short position may be covered by exercise of the option
described above in lieu of or in addition to open market purchases. In
addition, the contractual arrangements among the Underwriters include a
provision whereby, if the Representatives purchase Common Stock in the open
market for the account of the underwriting syndicate and the securities
purchased can be traced to a particular Underwriter or member of the selling
group, the underwriting syndicate may require the Underwriter or selling group
member in question to purchase the Common Stock in question at the cost price
to the syndicate or may recover from (or decline to pay to) the Underwriter or
selling group member in question the selling concession applicable to the
securities in question. The Underwriters are not required to engage in any of
these activities and any such activities, if commenced, may be discontinued at
any time.

  The Company and the Underwriters have agreed to indemnify each other against
certain liabilities, including liabilities under the Securities Act.
 
  The Company, its officers and directors and certain other stockholders,
holding in the aggregate substantially all of the Company's currently
outstanding equity securities, have agreed that, for a period of 180 days
after the date of this Prospectus, they will not, without the prior written
consent of Smith Barney Inc., offer, sell, contract to sell or otherwise
dispose of any shares of Common Stock or any securities convertible into, or
exercisable or exchangeable for, Common Stock except, in the case of the
Company, in certain limited circumstances and, in some cases, for certain
transfers to affiliated parties.
 
  Prior to the Offering, there has not been any public market for the Common
Stock of the Company. Consequently, the initial public offering price for the
shares of Common Stock included in the Offering has been determined by
negotiations between the Company and the Representatives. Among the factors
considered in determining such price were the history of and prospects for the
Company's business and the industry in which it competes, an assessment of the
Company's management and the present state of the Company's development, the
past and present revenues and earnings of the Company, the prospects for
growth of the Company's revenues and earnings, the current state of the
economy in the United States and the current level of economic activity in the
industry in which the Company competes and in related or comparable
industries, and currently prevailing conditions in the securities markets,
including current market valuations of publicly traded companies which are
comparable to the Company.

                            ADDITIONAL INFORMATION
 
  The Company has filed with the Commission, a Registration Statement on Form
S-1 under the Securities Act of 1933 with respect to the Common Stock being
offered hereby. This Prospectus does not contain all the information set forth
in the Registration Statement on Form S-1, as amended, and the exhibits and

                            PRA INTERNATIONAL, INC.
 
             PRO FORMA CONDENSED CONSOLIDATED STATEMENTS OF INCOME
                                  (UNAUDITED)
 
  In April, 1997 PRA International, Inc. ("PRA International") acquired the
outstanding stock of International Medical Technical Consultants, Inc.
("IMTCI") for $8.0 million in cash, 143,272 shares of previously unissued PRA
Common Stock valued at $2.0 million and $5.3 million in seller notes payable.
In addition, PRA International incurred certain acquisition expenses totaling
approximately $294,000. The acquisition is being accounted for in accordance
with the purchase method of accounting and the results of IMTCI are
consolidated with PRA International from the date of acquisition.
   
  The following unaudited Pro Forma Condensed Consolidated Statements of
Income give effect to the acquisition of IMTCI by PRA International as if the
acquisition had occurred on January 1, 1996. These pro forma statements of
income give effect, for the period presented to the following pro forma
adjustments: (a) the increase in amortization associated with goodwill
resulting from the acquisition; (b) the increase in interest expense
associated with the issuance of the convertible seller notes payable; (c) the
reduction of interest income earned by PRA for the period from PRA
International's 1996 Preferred Stock issuance to its acquisition of IMTCI; and
(d) the change in weighted average common shares outstanding resulting from
the issuance of 143,272 shares of common stock in connection with the
acquisition.     
 
  The following unaudited Pro Forma Condensed Consolidated Statements of
Income should be read in conjunction with the notes thereto included herewith,
with PRA International's audited consolidated financial statements and notes
thereto for the periods presented and with IMTCI's audited and unaudited
financial statements and notes thereto for the periods presented. The
unaudited Pro Forma Condensed Consolidated Statements of Income are not
necessarily indicative of future operating results or of what would have
occurred had the acquisition been consummated at the time specified. The pro
forma adjustments are based on available information and certain adjustments
that management believes to be reasonable. In the opinion of management, all
material adjustments have been made that are necessary to present fairly the
pro forma information.

  (1) Reflects the results of IMTCI on a stand alone basis for the period from
November 1, 1995 through September 30, 1996.
 
  (2) Represents adjustments to record the difference between the carrying
amount of the redeemable common stock warrants and the Series A Preferred
Stock and their respective redemption amounts. Also included are dividends
paid and accrued on preferred stock. The redemption feature of the redeemable
common stock warrants was removed in October 1996. The redemption feature of
the Series A Preferred Stock will expire and accrued dividends will be
forfeited upon the effectiveness of a qualified initial public offering (see
Notes 3 and 8 to the Consolidated Financial Statements).
   
  (3) Pro forma net income (loss) per share is computed assuming conversion of
the Series A Preferred Stock upon effectiveness of the Offering as discussed
in Note 3 in Notes to Consolidated Financial Statements, adjusted for the
elimination of interest expense associated with long-term debt the Company
expects to repay with proceeds from the offering, as follows:

  For purposes of computing pro forma net income (loss) per share, as
adjusted, weighted average shares outstanding, as reported, has been adjusted
by 868,729 and 940,433 shares for the year ended December 31, 1996 and the
nine months ended September 30, 1997, respectively to reflect the issuance of
a sufficient number of additional shares to repay such debt.     
 
  (4) Reflects the consolidated results of PRA International, including IMTCI
for the period from the acquisition of IMTCI on April 1, 1997 through
September 30, 1997.
 
  (5) Reflects the results of IMTCI on a stand alone basis for the period from
January 1, 1997 through March 31, 1997.
   
  (A) Reflects increase in amortization expense associated with goodwill
recorded on the IMTCI acquisition as if the acquisition had occurred as of the
beginning of the period. In connection with the acquisition, the Company
recorded approximately $13.6 million in goodwill which is being amortized on a
straight-line basis over a forty year period. See Note 2 to the Consolidated
Financial Statements for a description of the allocation of the purchase price
associated with the IMTCI acquisition.     
   
  (B) Reflects increase in interest expense associated with the issuance of
the seller notes payable assuming that the seller notes payable had been
issued as of the beginning of the period presented. The Company issued seller
notes payable in the amounts of $4.3 million and $1.0 million. Interest
accrues monthly on both notes at a rate of 8.33 percent per annum.     
   
  (C) Reflects the reduction in interest income earned by PRA International
for the period from the 1996 Preferred Stock issuance to its acquisition of
IMTCI. This adjustment assumes that $8 million of cash received from the
Preferred Stock issuance was paid to shareholders of IMTCI on January 1, 1996.
The reduction in interest income was calculated using an interest rate of
approximately 6 percent.     
   
  (D) Reflects the issuance of 143,272 shares of PRA International Common
Stock issued to the shareholders of IMTCI as if the transaction had been
consummated as of the beginning of the period. The pro forma adjustment for
the nine month period ended September 30, 1997 is adjusted to reflect the
inclusion of the IMTCI shares issued in April 1997 in the Company's pro forma
weighted average shares outstanding for the nine month period ended September
30, 1997.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To PRA International, Inc.:
   
  We have audited the accompanying consolidated balance sheet of PRA
International, Inc. (a Delaware corporation), as of December 31, 1996, and the
related consolidated statements of income, stockholders' deficit, and cash
flows for the year then ended. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these consolidated financial statements based on our audit.     
   
  We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform an audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.     
   
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of PRA International, Inc., as of December 31, 1996, and the consolidated
results of its operations and its cash flows for the year then ended, in
conformity with generally accepted accounting principles.     
 
  As explained in Note 3 to the consolidated financial statements, effective
January 1, 1996, the Company changed its method of accounting for depreciation
of fixed assets for certain fixed assets acquired subsequent to January 1,
1996.

  AS OF DECEMBER 31, 1995 AND 1996, AND SEPTEMBER 30, 1997 (INFORMATION AS OF
 AND FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1996 AND 1997, IS UNAUDITED)     
 
1. ORGANIZATION AND OPERATIONS:
 
ORGANIZATION AND RECAPITALIZATION
 
  PRA International, Inc. ("PRA International"), a holding company for
Pharmaceutical Research Associates, Inc. ("Associates"), was incorporated
under the state laws of Delaware in August 1996. Associates was incorporated
under the state laws of Virginia in April 1982. In 1996, pursuant to the
Agreement and Plan of Share Exchange (or "Recapitalization"), PRA
International, Associates, and all stockholders agreed to exchange all of the
outstanding common and preferred stock of Associates for an equal amount of a
single class of $0.01 par value common stock of PRA International. Prior to
the exchange of shares, all of the preferred stock of Associates was
convertible into voting common stock of Associates, at the option of the
holder. The proportionate interest of the stockholders was unaffected by the
Recapitalization. The consolidated financial statements included herein for
all periods prior to the Recapitalization are those of Associates.
 
CONSOLIDATION
 
  The accompanying consolidated financial statements include the accounts of
PRA International and its wholly owned subsidiaries, Associates, Pharm.
Research Associates (UK) Limited ("PRA Limited"), Pharmaceutical Research
Associates GmbH ("PRA GmbH"), International Medical Technical Consultants,
Inc. ("IMTCI"), and the Crucible Group, Inc. ("Crucible") collectively
hereafter referred to as the "Company." All significant intercompany accounts
and transactions have been eliminated in consolidation.
 
NATURE OF OPERATIONS
 
  The Company is a full-service international contract research organization
providing a broad range of product development services for pharmaceutical and
biotechnology companies. The Company's integrated services include data
management, statistical analysis, clinical trials management, clinical study
and protocol design, and regulatory and drug development consulting. The
Company provides these services throughout the United States, Canada, and
Europe.
 
RISKS AND OTHER FACTORS
 
  The Company's revenues are highly dependent on research and development
expenditures of the pharmaceutical and biotechnology industries. The Company
has and will likely continue to derive a substantial portion of its revenues
from a relatively limited number of major programs or clients (see Note 3).
The reduction in research and development expenditures by the pharmaceutical
or biotechnology industries or the loss of any one or more significant clients
could have a material adverse effect on the Company and its results of
operations.
 
  Clients of the Company may generally terminate contracts without cause, upon
30 to 60 days' notice. While the Company generally negotiates payments and
early termination fees up front, such terminations could significantly impact
the level of staff utilization and have a material adverse effect on the
Company and its results of operations.
 
  As discussed in Note 2, the Company acquired IMTCI, a site management
organization ("SMO"), in April 1997. IMTCI derives revenues from
investigational site management operations. Revenues from SMO-related
operations result primarily from pharmaceutical and biotechnology clients and
competing CROs. Some other CROs may be reluctant to utilize the Company's SMO
operations, which could have a material adverse impact on the Company's SMO-
related operations. Furthermore, the integration of a newly acquired business
involves numerous risks, including costs incurred in effecting the
acquisition, difficulty in assimilating operations and products, and the
potential loss of key employees. There can be no assurance that this or any
future acquisition

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
will be successfully integrated into the Company's operations. Accordingly,
there can be no assurances that the Company's management will be able to
sustain, on a combined basis, the current operating performance of the stand-
alone entities.
 
2. ACQUISITIONS:
 
  In April 1997, the Company acquired the outstanding stock of IMTCI, a
clinical research and site management organization, for $8,000,000 in cash,
143,272 shares of the Company's common stock valued at $2,000,000 and
approximately $5,343,000 in convertible notes payable (the "Seller Notes"). The
Seller Notes accrue interest at a rate of 8.33 percent per annum. The
acquisition was accounted for as a purchase, with the excess of the acquisition
cost over the fair value of IMTCI's net assets being assigned to goodwill. The
Company is amortizing the goodwill over a 40-year period. Results of operations
of IMTCI are included in the consolidated financial statements subsequent to
March 31, 1997.
 
  The purchase price was allocated as follows:

  Net loss available to common stockholders and net loss per share include
those pro forma adjustments discussed in Note 3 and as presented in the
accompanying consolidated statements of income, adjusted for the elimination of
interest expense associated with debt the Company expects to repay with the
proceeds from the offering and the pro forma effects of the IMTCI acquisition.
    
  In May 1997, the Company acquired Crucible, a clinical research and site
management organization, for $300,000 in cash. The acquisition was accounted
for as a purchase, with the excess of the acquisition cost over the fair value
of Crucible's net assets of approximately $587,000 being assigned to goodwill
and amortized over 15 years. Results of operations of Crucible are included in
the consolidated financial statements subsequent to the date of acquisition.
Pro forma results are not presented as they are not material to the
consolidated financial statements.
 
3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
INTERIM FINANCIAL STATEMENTS
   
  The unaudited consolidated statements of operations and cash flows for the
nine months ended September 30, 1996 and 1997, have been prepared by the
Company and, in the opinion of management, include     
 
                                      F-16

                            PRA INTERNATIONAL, INC.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
   
all adjustments (consisting of normal recurring adjustments) necessary to
present fairly the Company's results of operations and cash flows. The
operating results for the nine months ended September 30, 1997, are not
necessarily indicative of the results that may be expected for the year ending
December 31, 1997, or for any future, interim period.     
 
UNAUDITED PRO FORMA BALANCE SHEET AND PRO FORMA NET INCOME OR LOSS PER SHARE
   
  If the offering contemplated by this prospectus is consummated, all of the
Series A redeemable convertible preferred stock ("Series A Preferred Stock")
outstanding as of the closing date will automatically be converted into shares
of common stock. The pro forma balance sheet as of September 30, 1997,
reflects the conversion of the outstanding shares of Series A Preferred Stock
into 3,266,422 shares of common stock.     
   
  Pro forma net income or loss per share gives effect to: (i) the forfeiture
of accrued dividends on the Series A Preferred Stock upon automatic conversion
into common stock and (ii) the expiration of the redemption rights on the
Series A Preferred Stock.     
 
  As discussed in Note 8 to these consolidated financial statements, the
Series A Preferred Stock will automatically convert provided that the offering
price per share yields a minimum rate of return to the Series A Preferred
stockholders and the net offering proceeds are at least $25 million. The
Series A Preferred stockholders, have waived these requirements for an
offering which closes prior to January 31, 1998.
   
  Pro forma weighted-average shares used in computing pro forma net income per
share are based on the weighted-average number of shares outstanding during
the periods presented. Pursuant to the Securities and Exchange Commission
Staff Accounting Bulletin No. 83, all shares, options, and warrants issued
during the 12 months immediately preceding the initial public offering were
treated as if they had been outstanding for all periods presented, using the
treasury stock method and at a per share price of $11.00, the midpoint of the
proposed offering range.     
 
  Historical earnings per share data have been omitted because the automatic
conversion of the Series A Preferred Stock into common stock materially
changes the Company's capitalization. Primary income or loss per share is not
presented as it would not materially differ from the amounts presented.
   
SUPPLEMENTAL PRO FORMA NET INCOME (LOSS) PER SHARE     
   
  The Company anticipates repaying approximately $10.1 million in certain long
term debt with proceeds from the offering contemplated by this prospectus.
Assuming such repayment, supplemental pro forma net income (loss) per share,
adjusted to give effect for the elimination of interest associated with such
debt, would have been (0.12) and 0.07 for the year ended December 31, 1996 and
the nine month period ended September 30, 1997, respectively. For purposes of
this supplemental pro forma presentation, weighted average shares outstanding
has been adjusted for the estimated number of shares that the Company would
need to issue to repay the long-term debt discussed above, using the midpoint
of the offering range.     
   
  In March 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 128, "Earnings per Share." SFAS
No. 128 is effective for financial statements issued after December 15, 1997.
SFAS No. 128 requires dual presentation of basic and diluted earnings per
share. Basic earnings per share includes no dilution and is computed by
dividing net income or loss available to common stockholders by the weighted-
average number of common shares outstanding for the period. The Company's
basic net (loss) income per share, respectively, for the year ended December
31, 1996, and the nine months ended September 30, 1997, was $(0.12) and $   on
a pro forma basis.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
INCREASE IN AUTHORIZED SHARES AND STOCK SPLIT IN THE FORM OF A STOCK DIVIDEND
   
  In October 1997 the Company amended and restated its certificate of
incorporation to increase the number of authorized shares of common stock to
25 million shares, with a par value of $0.01 per share. The Company is also
authorized to issue up to 5,000,000 shares of preferred stock, par value $.01
per share, in one or more series, and, to the extent permitted by law, to fix
the rights, preferences, privileges and restrictions without any further vote
or action by the stockholders of the Company. In addition, the Company
effected a 1.97-for-one stock split of the common stock in the form of a stock
dividend. Accordingly, all share and per share amounts have been retroactively
adjusted to give effect to these events.     
 
USE OF ESTIMATES
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
CASH EQUIVALENTS
 
  The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.
 
UNBILLED SERVICES
 
  Unbilled services represent amounts earned for services that have been
rendered but for which clients have not been billed. Unbilled services are
generally billable upon achievement of contract milestones, contract
completion, or submission of appropriate billing information.
 
FIXED ASSETS
 
  Fixed assets are recorded at cost and are depreciated over the following
estimated useful lives:
 
<TABLE>
     <S>                                          <C>
     Furniture and fixtures...................... 7 years
     Computer equipment and purchased software... 3-5 years
     Leasehold improvements...................... The shorter of 10 years or the
                                                   lease term
</TABLE>
 
  For furniture, fixtures, and computer equipment of Associates purchased
prior to January 1, 1996, depreciation is computed using an accelerated
method. Assets of these classes purchased after December 31, 1995, are
depreciated using the straight-line method. The effect of this change was to
increase net income by approximately $376,000 during 1996 and decrease pro
forma loss per share by approximately $0.07 per share. Leasehold improvements
and property held under capital leases are depreciated over the shorter of the
life of the lease or the estimated useful life of the asset.
 
IMPAIRMENT OF LONG-LIVED ASSETS
   
  The Company reviews its long-lived assets, including goodwill resulting from
business acquisitions, and property and equipment, for impairment whenever
events or changes in circumstances indicate that the carrying amount of the
assets may not be fully recoverable. To determine recoverability of its long-
lived assets, the Company evaluates the probability that future undiscounted
net cash flows, without interest charges, will be less than the carrying
amount of the assets. The Company has determined that as of September 30,
1997, there has been no impairment in the carrying value of long-lived assets.

FAIR VALUE OF FINANCIAL INSTRUMENTS
 
  The carrying amounts of current assets and current liabilities in the
accompanying financial statements approximate fair value due to the short
maturity of these instruments.
   
  As of September 30, 1997, the fair value of the senior subordinated note
payable approximated $2,000,000. As of September 30, 1997, the fair value of
the Seller Notes payable, note payable to a bank, equipment loan and the line
of credit, approximated their carrying values. The fair value of the Company's
long-term debt was estimated using discounted cash flow analyses using
interest rates offered on loans with similar terms to borrowers of similar
credit quality.     
 
ADVANCE BILLINGS
 
  Advance billings represent amounts associated with services that have been
prebilled, but have not yet been rendered.
 
REVENUE RECOGNITION
   
  The majority of the Company's revenues are generated under fixed-price
contracts. Revenues from fixed-price contracts are recorded using the
percentage-of-completion method based on the relationship of costs incurred to
total estimated costs. The Company uses this method because management
considers total costs incurred to be the best available measure of progress on
these contracts. The estimated total costs of contracts are reviewed and
revised periodically throughout the lives of the contracts with adjustment to
revenue resulting from such revisions being recorded on a cumulative basis in
the period in which the revisions are made. A majority of the Company's
contracts undergo modifications over the contract period. Revenues related to
contract modifications are recognized when realization is assured and the
amounts are reasonably determinable. Contract costs consist primarily of
direct labor and other related labor costs. Pass-through expenses generally
include investigator fees, travel, and certain other contract costs that are
reimbursed by the customer. Accordingly, such costs are deducted in
determining net revenues.     
 
  If it is determined that a loss will result from performance under a
contract, the entire amount of the loss is charged against income in the
period in which the determination is made. Clients generally may terminate a
study at any time, which may cause periods of excess capacity and may
significantly reduce revenues and earnings. To offset the effects of any
terminations, the Company typically negotiates the payment of early
termination fees.
 
SIGNIFICANT CUSTOMERS
 
  Net revenues from individual customers greater than 10 percent of
consolidated net revenues in the respective periods were as follows:

  Due to the nature of the Company's business and the relative size of certain
contracts, it is not unusual for a significant customer in one year to be
insignificant in the next. However, the loss of any single significant
customer could have a material adverse effect on the Company's results from
operations.

CONCENTRATIONS OF CREDIT RISK
   
  Financial instruments that potentially subject the Company to credit risk
consist of accounts receivable, unbilled services and cash and cash
equivalents. Accounts receivable and unbilled services include amounts due
from pharmaceutical and biotechnology companies. Accounts receivable and
unbilled services from individual customers that are greater than 10 percent
of consolidated accounts receivable and unbilled services in the respective
periods were as follows:

  The Company provides reserves for potential credit losses. In management's
opinion, there is no additional credit risk beyond amounts provided for such
losses.
   
  As of September 30, 1997, the Company had invested approximately $251,000 in
overnight repurchase agreements. The underlying collateral consists of U.S.
government securities and U.S. government agency securities. Generally, the
maturity date of the Company's repurchase agreements is the next business day.
Due to the short-term nature of the agreements, the Company does not take
possession of the securities, which are instead held at the Company's bank
from which it purchases the securities. The carrying value of the agreements
approximates fair value because of the short maturity of the investments. As a
result, the Company believes that it is not exposed to any significant risk
under its overnight repurchase agreements.     
 
FOREIGN CURRENCY TRANSLATION
 
  The assets and liabilities of the Company's foreign subsidiaries are
translated into U.S. dollars at exchange rates in effect as of the end of the
period. Revenue and expense accounts and cash flows of these operations are
translated at average exchange rates prevailing during the period the
transactions occurred. Translation gains and losses are included as an
adjustment to the cumulative foreign currency translation adjustment account
in stockholders' deficit. Transaction gains and losses are included in other
income (expense), net, in the accompanying consolidated statements of income.
 
RECLASSIFICATIONS
 
  The Company has reclassified the December 31, 1995, redemption value of the
Class E redeemable preferred stock and redeemable common stock warrants of
$250,000 and $1,043,701, respectively, from stockholders' deficit to a
liability in order to conform with presentation requirements of the Securities
and Exchange Commission. In addition, certain other prior year amounts have
been reclassified to conform to the current period's presentation.
 
RECENT AUTHORITATIVE PRONOUNCEMENTS
 
  In June 1997, the Financial Accounting Standards Board issued SFAS No. 130,
"Reporting Comprehensive Income." SFAS No. 130 is effective for fiscal years
beginning after December 15, 1997. SFAS No. 130 establishes standards for
reporting and display of comprehensive income and its components in a full set
of general purpose financial statements. Comprehensive income is the total of
net income and all other nonowner changes in equity.

  In June 1997, the Financial Accounting Standards Board issued SFAS No. 131,
"Disclosures about Segments of an Enterprise and Related Information." SFAS
No. 131 is effective for financial statements for periods beginning after
December 15, 1997. SFAS No. 131 requires an enterprise to report certain
additional financial and descriptive information about its reportable
operating segments.     
  Management does not expect that the implementation of either SFAS No. 130 or

Note 8). The debentures were due in equal annual installments of $375,000 on
December 31, 1997 and 1998. Interest was payable in monthly installments on
the unpaid balance of the debt at an annual rate of 12.5 percent. The
debentures were secured by all of the assets of the Company and were
subordinated to the $2,000,000 senior subordinated note payable, as discussed
below, and up to $5,000,000 of senior notes and other financing. In August
1997, the Company repaid the $750,000 junior subordinated debenture with
proceeds from the Revolver discussed below.
 
  On August 11, 1995, the Company entered into a borrowing agreement with a
different investor whereby the Company received $2,000,000 in exchange for a
senior subordinated note payable and a warrant (see Note 8). The Company
originally allocated $329,095 of the proceeds to the warrant and debt
discount. The discount is being amortized to interest expense using the
effective interest method over the period the related debt is expected to be
outstanding. The total amount of the principal ($2,000,000), plus any unpaid
interest, is due on August 10, 2000. Interest is payable in monthly
installments at an annual rate of 13.5 percent. The agreement is secured by
all of the assets of the Company, but is subordinated to up to $10,000,000 of
other senior financing.
 
  In conjunction with the Crucible acquisition discussed in Note 2, the
Company assumed a note payable, which it immediately repaid with the proceeds
from a note payable to a bank. The note accrued interest at a rate of LIBOR
plus 2 percent per annum and was unsecured. In August 1997, the Company repaid
the note with proceeds from the Revolver discussed below.
   
  IMTCI had a line of credit with a bank, which provided for maximum
borrowings up to $750,000. Interest accrued at a rate of 8.25 percent per
annum on the outstanding borrowings. The line of credit was collateralized by
substantially all of IMTCI's assets. In August 1997, the line of credit was
repaid with proceeds from the Revolver discussed below.     
 
  In conjunction with the IMTCI acquisition, the Company assumed an equipment
loan. The loan accrued interest at a rate of 8.75 percent per annum and was
secured by certain equipment of IMTCI. In August 1997, the Company repaid the
loan with proceeds from the Revolver discussed below.
   
  The Company leases certain equipment having an original cost basis of
approximately $18,000, $25,000, and $713,000 as of December 31, 1995 and 1996,
and September 30, 1997, respectively. Accumulated depreciation of
approximately $9,000, $10,000, and $75,000 has been recorded as of December
31, 1995 and 1996, and September 30, 1997, respectively. Interest on the
leases is imputed at rates ranging from 6 to 18 percent as of September 30,
1997. The leases expire in various years through 2002 and, as of September 30,
1997, have remaining aggregate annual payments of approximately $84,000,
$266,000, $243,000, $120,000, $15,000, and $4,000 during 1997 through 2002,
including interest of approximately $47,000.     
   
  During August 1997, the Company obtained a revolving line of credit (the
"Revolver") with a bank, with maximum borrowings of up to $7,500,000.
Outstanding borrowings under the Revolver were approximately $2.8 million as
of September 30, 1997. Borrowings are limited to 85 percent of eligible billed
domestic accounts receivable and 60 percent of eligible unbilled domestic
accounts receivable and are collateralized by substantially all of the
Company's assets. Outstanding borrowings accrue interest at LIBOR
(approximately 5.9 percent as of September 30, 1997) plus 2 percent. The
Company utilized proceeds from the Revolver to retire $3,100,000 in long-term
debt. The Revolver carries certain financial covenants, including minimum
tangible net worth, minimum working capital, minimum debt service ratios,
limitations on capital expenditures and restrictions on the payment of
dividends, among others. The Revolver matures in June 1999.     
   
  During August 1997, PRA GmbH secured a line of credit facility providing for
aggregate borrowings up to DM 1,000,000 (approximately $568,000). The facility
accrues interest at a rate of 7.75 percent per annum on all outstanding
borrowings and is secured by the accounts receivable of PRA GmbH. The line of
credit facility has no expiration date.

SELLER NOTES PAYABLE
   
  In conjunction with the IMTCI acquisition (see Note 2), the Company issued
notes payable (the "Seller Notes") in the amounts of approximately $4,300,000
and $1,000,000 to the former owners of IMTCI. The $4,300,000 note matures in
April 2001 and is payable in quarterly installments beginning on October 1,
1997. The $1,000,000 note matures in April 2000 and is payable in 3 annual
installments of $333,333. The Seller Notes are subordinated to the Company's
long-term debt and the Revolver. Interest accrues monthly and is payable
quarterly, at 8.33 percent per annum. In the event of an initial public
offering, the Seller Notes are convertible, at the option of the holders, into
common stock of the Company, using the initial public offering price. The
holders of the Seller Notes have given notice to the Company that they elected
not to convert the Seller Notes into common stock of the Company.     
 
7. INCOME TAXES:
 
  The Company accounts for income taxes under SFAS No. 109, "Accounting for
Income Taxes." SFAS No. 109 requires the determination of deferred tax assets
and liabilities based on the difference between the financial statement and
income tax bases of assets and liabilities, using enacted tax rates in effect
for the year in which the differences are expected to reverse. The measurement
of a deferred tax asset is adjusted by a valuation allowance, if necessary, to
recognize tax benefits only to the extent that, based on available evidence,
it is more likely than not that they will be realized.
 
  The provision for income taxes was as follows:

  In determining the extent to which a valuation allowance for net deferred
tax assets is required, the Company evaluates all available evidence including
projections of future taxable income, carryback opportunities, and other tax
planning strategies. During 1996, the valuation allowance for deferred tax
assets decreased by approximately $289,000. This was the result of the
utilization of previously unrecognized deferred tax assets. The remaining
valuation allowance relates to foreign net operating losses as to which the
Company is unable to make a judgement about the likelihood of realization. The
Company believes that it is more likely than not that the net deferred tax
asset will be realized.     
 
8. REDEEMABLE CONVERTIBLE PREFERRED STOCK AND COMMON STOCK WARRANTS:
 
SERIES A, REDEEMABLE, CONVERTIBLE, PREFERRED STOCK
 
  In October and November 1996, the Company issued 1,658,082 shares of Series
A Preferred Stock for approximately $19,371,000. The issuance of the Series A
Preferred Stock was recorded net of approximately $518,000 in stock issuance
costs.

<PAGE>
 
                            PRA INTERNATIONAL, INC.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  The Series A Preferred Stock may be automatically or electively converted or
mandatorily redeemed upon the occurrence of an Extraordinary Event, Liquidity
Event, or the passage of time.
 
  An Extraordinary Event occurs upon (1) a merger or consolidation with
another entity, (2) a reorganization or recapitalization, (3) an initial
public offering, or (4) disposition of substantially all of the Company's
assets.
 
  If an Extraordinary Event results or is expected to result in a cumulative
internal rate of return to the Series A Preferred stockholders of at least 33
percent, that Extraordinary Event shall be deemed a Liquidity Event. The
Company may pay some or all of the accrued Series A Preferred Stock dividends
to the holders to achieve a Liquidity Event. For an initial public offering to
qualify as a Liquidity Event, net proceeds from the offering must equal or
exceed $25 million. The Series A Preferred stockholders' have waived the
minimum investment return and minimum net proceeds requirements necessary for
an initial public offering to qualify as a Liquidity Event provided that an
initial public offering closes prior to January 31, 1998.
 
  Upon the occurrence of an Extraordinary Event that is not a Liquidity Event,
the Company shall issue to the Series A Preferred stockholders additional
warrants with the right to purchase common stock of the Company for a price of
$.01 per warrant. The number of warrants to be issued in such instances shall
be sufficient based on the fair value of the Company's common stock at such
time, and when added to the original purchase price of the Series A Preferred
Stock, to result in an internal rate of return to the Series A Preferred
stockholders of not less than 33 percent, including all accrued dividends paid
in cash or additional shares of stock. In no case, however, shall the number
of shares of common stock issuable pursuant to such warrant exceed 642,831.
 
 Automatic Conversion
   
  Upon the closing of an initial public offering, the merger, or the of sale
of the Company prior to November 1, 1998, that qualifies as a Liquidity Event,
all outstanding shares of Series A Preferred Stock shall automatically convert
into common stock. Each share of Series A Preferred Stock shall be converted
to common stock of the Company based on a ratio defined in the stock purchase
agreement. The number of shares originally issued is subject to future
adjustment to prevent dilution of the Series A Preferred stockholders'
proportionate interests. The conversion ratio as of September 30, 1997, was
1.97-for-one.     
 
  If a Liquidity Event occurs, all accrued dividends on the Series A Preferred
Stock shall be forfeited.
 
 Optional Conversion
 
  Each share of Series A Preferred Stock is convertible, at the option of the
holder, into common stock of the Company determined in proportion to the ratio
of $11.68, the issuance price, to the Conversion Price per share, as defined.
Additionally, upon conversion, the Company shall issue an additional number of
shares of common stock to the holder of the converted Series A Preferred Stock
equal to the amount of accrued and unpaid dividends divided by the Conversion
Price then in effect, but only if the holders have not achieved the prescribed
33 percent internal rate of return.
 
 Redemption Features
   
  The Series A Preferred Stock is redeemable, at the option of the holders,
upon the occurrence of an Extraordinary Event that is not a Liquidity Event.
In the event of such an occurrence, the Series A Preferred Stock can be
redeemed at a per share price equal to the Conversion Price, as defined,
including all accrued and unpaid dividends. The Conversion Price as of
September 30, 1997, excluding accrued dividends, was $11.68, which was equal
to the issuance price.     
 
  Upon the occurrence of a Liquidity Event after November 1, 1998, the Series
A Preferred Stock can be redeemed at a price equal to the Conversion Price as
of the date of the Liquidity Event, plus any accrued and unpaid dividends.

                            PRA INTERNATIONAL, INC.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  To the extent that any Series A Preferred Stock remains outstanding as of
October 11, 2001, the holders of the Series A Preferred Stock may redeem their
shares in three equal annual installments beginning on that date, at a price
equal to the Conversion Price, plus all accrued and unpaid dividends. The
difference between the carrying value of the Series A Preferred Stock and its
redemption value is being accreted over the period to the earliest date upon
which the Series A Preferred Stock may be redeemed, not withstanding the
occurrence of an Extraordinary Event, using the effective interest method.
 
DIVIDENDS
   
  The Series A Stock carries a cumulative dividend, which accrues quarterly,
at a rate of 9 percent per annum. Accrued dividends of approximately $344,000
and $1,656,000 have been included in the carrying value of the Preferred Stock
as of December 31, 1996, and September 30, 1997, respectively. If the offering
contemplated by this prospectus is consummated and closes prior to January 31,
1998, all of the accrued dividends on the Series A Preferred Stock will be
forfeited.     
 
  For any preferred stock not redeemed as of October 11, 2001, dividends shall
be paid at two thirds and one-third of the original amounts for the years
ended October 10, 2002 and 2003, respectively. No further dividends will
accrue on the preferred stock after October 10, 2003.
 
 Voting Rights
 
  Each share of preferred stock shall entitle the holder to the number of
votes equal to that which would exist if the preferred stock were converted
into common stock as of the date of any voting action.
 
 Liquidation Preference
 
  In the event of liquidation, dissolution, or winding up of the Company, the
holders of each share of preferred stock are entitled to redeem their shares
at an amount equal to the Conversion Price and all accrued and unpaid
dividends.
 
REDEEMABLE COMMON STOCK WARRANTS
 
  In November 1994, the Company entered into an agreement with an outside
investor whereby the Company received $1,000,000 in cash in exchange for
junior subordinated debentures, preferred stock, and a warrant. The Company
issued 105,419 shares of Class E convertible preferred stock at $2.37 per
share, or $250,000. The Class E preferred stock was convertible into common
stock. The Company also issued the investor a warrant (the "1994 Warrant") for
the purchase of 472,272 shares of common stock at a purchase price of $1.06
per share. The Class E preferred stock was converted into common stock in
1996.
 
  The original agreement stipulated certain put and call provisions whereby
the investor had the option to require the Company to purchase, and the
Company had the option to require the investors to sell to the Company, the
preferred stock and the common stock underlying the warrant. The purchase
price, or put value, was the fair value of the common stock at the time of
redemption. The estimated redemption value of the preferred stock and the 1994
Warrant was accreted until October 1996, at which time the preferred stock was
converted to common stock and the 1994 Warrant was amended to remove the put
and call provisions.
 
  The 1994 Warrant can be exercised at any time until its termination date of
November 2001. The warrant agreement originally contained certain antidilution
rights whereby the 1994 Warrant might be adjusted to ensure that the outside
investor maintained a certain percentage of the Company on a fully diluted
basis. In October 1996, these antidilution rights were amended and removed. In
August 1997, approximately 236,136 shares of common stock were issued pursuant
to the 1994 Warrant.

  In August 1995, the Company entered into an agreement with a different
outside investor whereby the Company received $2,000,000 in cash in exchange
for a senior subordinated note payable and a warrant (the "1995 Warrant") to
purchase 231,077 shares of common stock. The 1995 Warrant had an exercise
price of $.005 per share. The Company originally allocated $329,095 of the
senior subordinated note payable proceeds to the 1995 Warrant. The 1995
Warrant could be exercised at any time until its termination date of September
30, 2000. The warrant agreement stipulated certain put provisions whereby the
investor had the option to require the Company to purchase the common stock
underlying the 1995 Warrant. The estimated redemption value of the 1995
Warrant was accreted until October 1996, at which time the 1995 Warrant was
amended to remove the put provision. In April 1997, the 1995 Warrant was
exercised in full and the Company issued 231,077 shares of common stock to its
holder.

</TABLE>    
 
  In 1996, the holders of Class D and Class F preferred stock converted their
shares into shares of common stock in conjunction with the Recapitalization
discussed in Note 1.
 
STOCK REPURCHASE
 
  During October 1996, the Company repurchased 1,545,540 shares of outstanding
common stock from certain investors and employees for approximately
$9,172,000. Approximately $633,000 of this amount was expensed as compensation
as certain of the shares were repurchased immediately succeeding the exercise
of employee stock options. The repurchased shares have been recorded, net of
compensation expense discussed above, as treasury stock in the accompanying
consolidated financial statements.
 
STOCK DISTRIBUTION
 
  In 1996, the Company issued 206,986 shares of common and preferred stock to
certain common and preferred stockholders pursuant to anti-dilution protection
afforded those stockholders in their original stock purchase agreements.
 
STOCKHOLDERS' AGREEMENT
 
  Certain stockholders of the Company are party to a Stockholders' Agreement
which affords the Series A Preferred stockholders anti-dilution protection and
provides the Company and the Series A Preferred stockholders an option to
purchase any outstanding shares offered for sale by other stockholders in the
event of certain occurrences. The purchase price is the then fair market value
of the common stock. These purchase provisions will be terminated in
connection with the initial public offering.

SHORT-FORM STOCKHOLDERS' AGREEMENT
   
  The Company and certain optionholders are party to an agreement that
requires the Company to repurchase, in the event of death of the holder, any
stock options or common shares then outstanding at the then fair market value
of the Company's common stock. The agreement also provides the Company with
the option to repurchase any stock options or shares held at the then fair
market value in the event of certain other occurrences. There were no shares
of common stock outstanding as of December 31, 1996, or September 30, 1997,
which were subject to the repurchase provisions. The repurchase provisions
will be terminated in connection with the initial public offering.     
 
10. STOCK OPTIONS:
   
  Options generally vest over a four-year period and are exercisable over a
ten-year period from the date of grant. As of September 30, 1997, 138,491
shares were available for the issuance of stock options. As of September 30,
1997, 623,361 options to purchase shares of common stock were exercisable,
with a weighted average exercise price of $0.41.     
   
  The Company generally grants stock options with exercise prices at least
equal to the then fair market value of the Company's common stock, as
determined by the Board of Directors or an independent appraisal. Any
difference between the fair value of the stock and the exercise price is
recorded as compensation expense over the vesting period of the option. During
1996 and the nine months ended September 30, 1997, the Company recorded
compensation expense of approximately $11,000 and $33,000, respectively, for
options whose exercise price was less than the then fair market value of the
common stock at the date of grant, as determined by an independent appraisal.

  The Company accounts for employee stock options using the method of
accounting prescribed by Accounting Principles Board Opinion ("APB") No. 25,
"Accounting for Stock Issued to Employees." Under APB No. 25, compensation
expense is recorded for the difference, if any, between the fair market value
of the common stock at the date of the stock option grant and the exercise
price of the stock option. Effective January 1, 1996, the Company adopted SFAS
No. 123, "Accounting for Stock-Based Compensation," by making the required
footnote disclosures discussed below. Had compensation cost been determined
based on the stock's fair market value at the grant dates for awards under the
Company's stock option plan in accordance with SFAS No. 123, pro form net
income (loss) available to common stockholders and pro forma net income (loss)
available per share would have been reduced to the amounts for the years
indicated below:

  In November 1997, the Company and the University of Virginia Real Estate
Foundation entered into a lease of a four-story building comprising
approximately 76,000 square feet for the Company's Charlottesville, VA
operations. The lease has a fifteen-year term, renewable for up to two
additional five-year terms, with a base rental rate of $19.95 per square foot
for the first five years. The Company's occupancy of the building, which has
yet to be constructed, is scheduled to occur in the first quarter of 1999.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To International Medical Technical Consultants, Inc.:
 
We have audited the accompanying balance sheets of International Medical
Technical Consultants, Inc. (a Kansas corporation), as of September 30, 1995
and 1996, and the related statements of income, stockholders' equity and cash
flows for each of the two years in the period ended September 30, 1996. 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 International Medical
Technical Consultants, Inc., as of September 30, 1995 and 1996, and the
results of its operations and its cash flows for each of the two years in the
period ended September 30, 1996, in conformity with generally accepted
accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
 
                (INFORMATION AS OF MARCH 31, 1997, AND FOR THE
            SIX MONTHS ENDED MARCH 31, 1997 AND 1996 IS UNAUDITED)
 
1. SUMMARY OF OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES:
 
  International Medical Technical Consultants, Inc., a Kansas corporation (the
"Company"), is a contract research and management organization providing a
broad range of product development services for the pharmaceutical industry
primarily in the United States. The Company's integrated services include
information management, statistical analysis, clinical trials management,
clinical study design and regulatory consulting.
 
  On April 1, 1997, PRA International, Inc. purchased all of the outstanding
common stock of the Company. The purchase price consisted of $8 million in
cash, approximately $5.3 million in notes payable, and $2 million of stock in
PRA International, Inc.
 
FISCAL YEAR AND INTERIM FINANCIAL INFORMATION
 
  Prior to its acquisition by PRA International, Inc., the Company operated on
a fiscal year ending on September 30. The financial statements presented are
as of and for the years ended September 30, 1995 and 1996, referred to herein
as 1995 and 1996, respectively. The unaudited financial statements as of
March 31, 1996 and 1997, include, in the opinion of management, all
adjustments (consisting of normal recurring adjustments) necessary to present
fairly the Company's financial position, results of operations, and cash
flows. Operating results for the six months ended March 31, 1997, are not
necessarily indicative of the results that may be expected for the year ending
September 30, 1997.
 
USE OF ESTIMATES
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
REVENUE RECOGNITION
 
  Substantially all the Company's revenues are generated under fixed price
arrangements. The Company records revenues from fixed price contracts on a
percentage of completion basis. Revenues from time-and-materials contracts are
recognized using billable rates multiplied by hours delivered. Revenues
related to contract modifications are recognized when realization is assured
and the amounts are reasonably determinable. Reimbursed costs generally
include subcontractor costs which consist of investigator fees, travel and
certain other contract costs that are reimbursed by the sponsor. Accordingly,
such subcontractor costs are deducted in determining net revenues. In the
period in which it is determined that a loss will result from the performance
of a contract, the entire amount of the estimated loss is charged against
income.
 
CASH AND CASH EQUIVALENTS
 
  The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.
 
  As of September 30, 1995 and 1996 and March 31, 1997, cash and cash
equivalents consisted of money market investments and overnight investments in
U.S. government securities.
 
UNBILLED SERVICES
 
  Unbilled services represent amounts earned for services that have been
rendered but for which clients have not been billed. Unbilled services
represent work-in-process that are billable upon achievement of contract
milestones, contract completion or submission of appropriate billing
information.

PROPERTY AND EQUIPMENT
 
  Property and equipment is recorded at cost. Furniture and equipment and
vehicles are depreciated using the straight line method over the estimated
useful lives of the related assets, generally 5-7 years. Computer software is
amortized over 5 years. Leasehold improvements are amortized over the shorter
of the respective lives of the leases or the useful lives of the improvements.
 
INCOME TAXES
 
  The Company accounts for income taxes using the asset and liability method
as prescribed by Statement of Financial Accounting Standards No. 109,
"Accounting for Income Taxes."
 
ADVANCE BILLINGS
 
  Advance billings represent amounts billed and cash received for services not
yet rendered.
 
SIGNIFICANT CUSTOMERS
 
  During the year ended September 30, 1995, three customers represented 10,
28, and 16 percent of net revenues. During the year ended September 30, 1996,
two customers represented 22 and 18 percent of net revenues. For the six
months ended March 31, 1997, one customer represented 33 percent 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.
 
CONCENTRATIONS OF CREDIT RISK
 
  Financial instruments that potentially subject the Company to credit risk
consist of accounts receivable from pharmaceutical companies. Three customers,
two customers and two customers accounted for 46, 44, and 42 percent of
accounts receivable as of September 30, 1995 and 1996, and March 31, 1997,
respectively.
 
  The Company provides reserves for potential credit losses. In management's
opinion, there is no additional credit risk beyond amounts provided for such
losses.

8. EMPLOYEE BENEFIT PLAN:
 
  The Company maintains a 401(k) Profit Sharing Plan (the "Plan"), which
covers substantially all employees after one year of service. Eligible
employees may contribute up to 10 percent of their pretax salary, and the
Company will match a discretionary percentage of employee contributions. The
Company made contributions to the Plan of approximately $81,000 and $100,000
during 1995 and 1996, respectively. The Company made no contributions to the
Plan during the six months ended March 31, 1996 or 1997.
 
9. FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
  The carrying value of the Company's current financial assets and liabilities
approximates fair value due to the short-term maturity of such instruments.
 
  The fair value of the Company's long-term notes payable was estimated using
current rates offered to the Company for debt with similar terms. The fair
value of the Company's long-term notes payable approximates carrying value.
 
10. RELATED PARTY TRANSACTIONS:
 
  At September 30, 1995, 1996 and March 31, 1997, the Company had notes
receivable from stockholders totaling approximately $96,000, $232,000, and
$271,000, respectively. The notes are noninterest bearing and are payable upon
demand.
 
  The Company leases certain operating facilities from related parties (see
Note 6).

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 consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of PRA International, Inc., as of December 31, 1996 and June 30, 1997, and the
consolidated results of its operations and its cash flows for the six month
period then ended, in conformity with generally accepted accounting
principles.     
 
  As explained in Note 3 to the consolidated financial statements, effective
January 1, 1996, the Company changed its method of accounting for depreciation
of fixed assets for certain fixed assets acquired subsequent to January 1,
1996.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
     
  AS OF DECEMBER 31, 1996, AND JUNE 30, 1997 (INFORMATION FOR THE SIX MONTHS
                    ENDED JUNE 30, 1996 IS UNAUDITED)     
 
1. ORGANIZATION AND OPERATIONS:
 
ORGANIZATION AND RECAPITALIZATION
 
  PRA International, Inc. ("PRA International"), a holding company for
Pharmaceutical Research Associates, Inc. ("Associates"), was incorporated
under the state laws of Delaware in August 1996. Associates was incorporated
under the state laws of Virginia in April 1982. In 1996, pursuant to the
Agreement and Plan of Share Exchange (or "Recapitalization"), PRA
International, Associates, and all stockholders agreed to exchange all of the
outstanding common and preferred stock of Associates for an equal amount of a
single class of $0.01 par value common stock of PRA International. Prior to
the exchange of shares, all of the preferred stock of Associates was
convertible into voting common stock of Associates, at the option of the
holder. The proportionate interest of the stockholders was unaffected by the
Recapitalization. The consolidated financial statements included herein for
all periods prior to the Recapitalization are those of Associates.
 
CONSOLIDATION
 
  The accompanying consolidated financial statements include the accounts of
PRA International and its wholly owned subsidiaries, Associates, Pharm.
Research Associates (UK) Limited ("PRA Limited"), Pharmaceutical Research
Associates GmbH ("PRA GmbH"), International Medical Technical Consultants,
Inc. ("IMTCI"), and the Crucible Group, Inc. ("Crucible") collectively
hereafter referred to as the "Company." All significant intercompany accounts
and transactions have been eliminated in consolidation.
 
NATURE OF OPERATIONS
 
  The Company is a full-service international contract research organization
providing a broad range of product development services for pharmaceutical and
biotechnology companies. The Company's integrated services include data
management, statistical analysis, clinical trials management, clinical study
and protocol design, and regulatory and drug development consulting. The
Company provides these services throughout the United States, Canada, and
Europe.
 
RISKS AND OTHER FACTORS
 
  The Company's revenues are highly dependent on research and development
expenditures of the pharmaceutical and biotechnology industries. The Company
has and will likely continue to derive a substantial portion of its revenues
from a relatively limited number of major programs or clients (see Note 3).
The reduction in research and development expenditures by the pharmaceutical
or biotechnology industries or the loss of any one or more significant clients
could have a material adverse effect on the Company and its results of
operations.
 
  Clients of the Company may generally terminate contracts without cause, upon
30 to 60 days' notice. While the Company generally negotiates payments and
early termination fees up front, such terminations could significantly impact
the level of staff utilization and have a material adverse effect on the
Company and its results of operations.
 
  As discussed in Note 2, the Company acquired IMTCI, a site management
organization ("SMO"), in April 1997. IMTCI derives revenues from
investigational site management operations. Revenues from SMO-related
operations result primarily from pharmaceutical and biotechnology clients and
competing CROs. Some other CROs may be reluctant to utilize the Company's SMO
operations, which could have a material adverse impact on the Company's SMO-
related operations. Furthermore, the integration of a newly acquired business
involves numerous risks, including costs incurred in effecting the
acquisition, difficulty in assimilating operations and products, and the
potential loss of key employees. There can be no assurance that this or any
future acquisition

                            PRA INTERNATIONAL, INC.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
will be successfully integrated into the Company's operations. Accordingly,
there can be no assurances that the Company's management will be able to
sustain, on a combined basis, the current operating performance of the stand-
alone entities.
 
2. ACQUISITIONS:
 
  In April 1997, the Company acquired the outstanding stock of IMTCI, a
clinical research and site management organization, for $8,000,000 in cash,
143,272 shares of the Company's common stock valued at $2,000,000 and
approximately $5,330,000 in convertible notes payable (the "Seller Notes").
The Seller Notes accrue interest at a rate of 8.33 percent per annum. The
acquisition was accounted for as a purchase, with the excess of the
acquisition cost over the fair value of IMTCI's net assets being assigned to
goodwill. The Company is amortizing the goodwill over a 40-year period.
Results of operations of IMTCI are included in the consolidated financial
statements subsequent to March 31, 1997.
 
  The purchase price was allocated as follows:

  Net loss available to common stockholders and net loss per share include
those pro forma adjustments discussed in Note 3 and as presented in the
accompanying consolidated statements of income, adjusted for the elimination
of interest expense associated with debt the Company expects to repay with the
proceeds from the offering and the pro forma effects of the IMTCI acquisition.
    
  In May 1997, the Company acquired Crucible, a clinical research and site
management organization, for $300,000 in cash. The acquisition was accounted
for as a purchase, with the excess of the acquisition cost over the fair value
of Crucible's net assets of approximately $587,000 being assigned to goodwill
and amortized over 15 years. Results of operations of Crucible are included in
the consolidated financial statements subsequent to the date of acquisition.
Pro forma results are not presented as they are not material to the
consolidated financial statements.
 
3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
INTERIM FINANCIAL STATEMENTS
   
  The unaudited consolidated statements of operations and cash flows for the
six months ended June 30, 1996, have been prepared by the Company and, in the
opinion of management, include all adjustments (consisting of normal recurring
adjustments) necessary to present fairly the Company's results of operations
and cash flows.

                            PRA INTERNATIONAL, INC.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
The operating results for the six months ended June 30, 1997, are not
necessarily indicative of the results that may be expected for the year ending
December 31, 1997, or for any future, interim period.
       
INCREASE IN AUTHORIZED SHARES AND STOCK SPLIT IN THE FORM OF A STOCK DIVIDEND
   
  In October 1997 the Company amended and restated its certificate of
incorporation to increase the number of authorized shares of common stock to
25 million shares, with a par value of $0.01 per share. The Company is also
authorized to issue up to 5,000,000 shares of preferred stock, per value $.01
per share, in one or more series, and, to the extent permitted by law, to fix
the rights, preferences, privileges and restrictions without any further vote
as action by the stockholders of the Company. In addition, the Company
effected a 1.97-for-one stock split of the common stock in the form of a stock
dividend. Accordingly, all share and per share amounts have been retroactively
adjusted to give effect to these events.     
 
USE OF ESTIMATES
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
CASH EQUIVALENTS
 
  The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.
 
UNBILLED SERVICES
 
  Unbilled services represent amounts earned for services that have been
rendered but for which clients have not been billed. Unbilled services are
generally billable upon achievement of contract milestones, contract
completion, or submission of appropriate billing information.
 
FIXED ASSETS
 
  Fixed assets are recorded at cost and are depreciated over the following
estimated useful lives:
 
<TABLE>
     <S>                                          <C>
     Furniture and fixtures...................... 7 years
     Computer equipment and purchased software... 3-5 years
     Leasehold improvements...................... The shorter of 10 years or the
                                                   lease term
</TABLE>
 
  For furniture, fixtures, and computer equipment of Associates purchased
prior to January 1, 1996, depreciation is computed using an accelerated
method. Assets of these classes purchased after December 31, 1995, are
depreciated using the straight-line method. The effect of this change was to
increase net income by approximately $376,000 during 1996 and decrease pro
forma loss per share by approximately $0.07 per share. Leasehold improvements
and property held under capital leases are depreciated over the shorter of the
life of the lease or the estimated useful life of the asset.
 
IMPAIRMENT OF LONG-LIVED ASSETS
 
  The Company reviews its long-lived assets, including goodwill resulting from
business acquisitions, and property and equipment, for impairment whenever
events or changes in circumstances indicate that the carrying amount of the
assets may not be fully recoverable. To determine recoverability of its long-
lived assets, the Company evaluates the probability that future undiscounted
net cash flows, without interest charges, will be less than the carrying
amount of the assets. The Company has determined that as of June 30, 1997,
there has been no impairment in the carrying value of long-lived assets.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
  The carrying amounts of current assets and current liabilities in the
accompanying financial statements approximate fair value due to the short
maturity of these instruments.

                            PRA INTERNATIONAL, INC.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
   
  As of June 30, 1997, the fair value of the senior subordinated note payable
approximated $2,000,000. As of June 30, 1997, the fair value of the junior
subordinated debentures, Seller Notes payable, note payable to a bank,
equipment loan and the line of credit, approximated their carrying values. The
fair value of the Company's long-term debt was estimated using discounted cash
flow analyses using interest rates offered on loans with similar terms to
borrowers of similar credit quality.     
 
ADVANCE BILLINGS
 
  Advance billings represent amounts associated with services that have been
prebilled, but have not yet been rendered.
 
REVENUE RECOGNITION
   
  The majority of the Company's revenues are generated under fixed-price
contracts. Revenues from fixed-price contracts are recorded using the
percentage-of-completion method based on the relationship of costs incurred to
total estimated costs. The Company uses this method because management
considers total costs incurred to be the best available measure of progress on
these contracts. The estimated total costs of contracts are reviewed and
revised periodically throughout the lives of the contracts with adjustment to
revenue resulting from such revisions being recorded on a cumulative basis in
the period in which the revisions are made. A majority of the Company's
contracts undergo scope modification over the contract period. Revenues
related to contract modifications are recognized when realization is assured
and the amounts are reasonably determinable. Contract costs consist primarily
of direct labor and other related labor costs. Pass-through expenses generally
include investigator fees, travel, and certain other contract costs that are
reimbursed by the customer. Accordingly, such costs are deducted in
determining net revenues.     
 
  If it is determined that a loss will result from performance under a
contract, the entire amount of the loss is charged against income in the
period in which the determination is made. Clients generally may terminate a
study at any time, which may cause periods of excess capacity and may
significantly reduce revenues and earnings. To offset the effects of any
terminations, the Company typically negotiates the payment of early
termination fees.
 
SIGNIFICANT CUSTOMERS
 
  Net revenues from individual customers greater than 10 percent of
consolidated net revenues in the respective periods were as follows:

*  Less than 10% of consolidated net revenues.     
       
  Due to the nature of the Company's business and the relative size of certain
contracts, it is not unusual for a significant customer in one year to be
insignificant in the next. However, the loss of any single significant
customer could have a material adverse effect on the Company's results from
operations.

CONCENTRATIONS OF CREDIT RISK
   
  Financial instruments that potentially subject the Company to credit risk
consist of accounts receivable, unbilled services and cash and cash
equivalents. Accounts receivable and unbilled services include amounts due
from pharmaceutical and biotechnology companies. Accounts receivable and
unbilled services from individual customers that are greater than 10 percent
of consolidated accounts receivable and unbilled services in the respective
periods were as follows:

  The Company provides reserves for potential credit losses. In management's
opinion, there is no additional credit risk beyond amounts provided for such
losses.
 
  As of June 30, 1997, the Company had invested approximately $1,956,000 in
overnight repurchase agreements. The underlying collateral consists of U.S.
government securities and U.S. government agency securities. Generally, the
maturity date of the Company's repurchase agreements is the next business day.
Due to the short-term nature of the agreements, the Company does not take
possession of the securities, which are instead held at the Company's bank
from which it purchases the securities. The carrying value of the agreements
approximates fair value because of the short maturity of the investments. As a
result, the Company believes that it is not exposed to any significant risk
under its overnight repurchase agreements.
 
FOREIGN CURRENCY TRANSLATION
 
  The assets and liabilities of the Company's foreign subsidiaries are
translated into U.S. dollars at exchange rates in effect as of the end of the
period. Revenue and expense accounts and cash flows of these operations are
translated at average exchange rates prevailing during the period the
transactions occurred. Translation gains and losses are included as an
adjustment to the cumulative foreign currency translation adjustment account
in stockholders' deficit. Transaction gains and losses are included in other
income (expense), net, in the accompanying consolidated statements of income.
 
RECLASSIFICATIONS
 
  The Company has reclassified the December 31, 1995, redemption value of the
Class E redeemable preferred stock and redeemable common stock warrants of
$250,000 and $1,043,701, respectively, from stockholders' deficit to a
liability in order to conform with presentation requirements of the Securities
and Exchange Commission. In addition, certain other prior year amounts have
been reclassified to conform to the current period's presentation.
 
RECENT AUTHORITATIVE PRONOUNCEMENTS
 
  In June 1997, the Financial Accounting Standards Board issued SFAS No. 130,
"Reporting Comprehensive Income." SFAS No. 130 is effective for fiscal years
beginning after December 15, 1997. SFAS No. 130 establishes standards for
reporting and display of comprehensive income and its components in a full set
of general purpose financial statements. Comprehensive income is the total of
net income and all other nonowner changes in equity.

August 1997, the Company repaid the $750,000 junior subordinated debenture
with proceeds from the Revolver discussed below.
 
  On August 11, 1995, the Company entered into a borrowing agreement with a
different investor whereby the Company received $2,000,000 in exchange for a
senior subordinated note payable and a warrant (see Note 8). The Company
originally allocated $329,095 of the proceeds to the warrant and debt
discount. The discount is being amortized to interest expense using the
effective interest method over the period the related debt is expected to be
outstanding. The total amount of the principal ($2,000,000), plus any unpaid
interest, is due on August 10, 2000. Interest is payable in monthly
installments at an annual rate of 13.5 percent. The agreement is secured by
all of the assets of the Company, but is subordinated to up to $10,000,000 of
other senior financing.
 
  In conjunction with the Crucible acquisition discussed in Note 2, the
Company assumed a note payable, which it immediately repaid with the proceeds
from a note payable to a bank. The note accrued interest at a rate of LIBOR
plus 2 percent per annum and was unsecured. In August 1997, the Company repaid
the note with proceeds from the Revolver discussed below.
   
  IMTCI had a line of credit with a bank, which provided for maximum
borrowings up to $750,000. Interest accrued at a rate of 8.25 percent per
annum on the outstanding borrowings. Outstanding borrowings under the line of
credit were $500,000 as of June 30, 1997. The line of credit was
collateralized by substantially all of IMTCI's assets. In August 1997, the
line of credit was repaid with proceeds from the Revolver discussed below.
    
  In conjunction with the IMTCI acquisition, the Company assumed an equipment
loan. The loan accrued interest at a rate of 8.75 percent per annum and was
secured by certain equipment of IMTCI. In August 1997, the Company repaid the
loan with proceeds from the Revolver discussed below.
 
  The Company leases certain equipment having an original cost basis of
approximately $25,000 and $526,000 as of December 31, 1996, and June 30, 1997,
respectively. Accumulated depreciation of approximately $10,000 and $16,000
has been recorded as of December 31, 1996, and June 30, 1997, respectively.
Interest on the leases is imputed at rates ranging from 6 to 18 percent as of
June 30, 1997. The leases expire in various years through 2001 and, as of June
30, 1997, have remaining aggregate annual payments of approximately $110,000,
$154,000, $151,000, $146,000, and $60,000 during 1997 through 2001, including
interest of approximately $80,000.
 
  During August 1997, the Company obtained a revolving line of credit (the
"Revolver") with a bank, with maximum borrowings of up to $7,500,000.
Borrowings are limited to 85 percent of eligible billed domestic accounts
receivable and 60 percent of eligible unbilled domestic accounts receivable
and are collateralized by substantially all of the Company's assets.
Outstanding borrowings accrue interest at LIBOR (approximately 5.7 percent as
of August 30, 1997) plus 2 percent. The Company utilized proceeds from the
Revolver to retire $2,200,000 in long-term debt. The Revolver carries certain
financial covenants, including minimum tangible net worth, minimum working
capital, minimum debt service ratios, limitations on capital expenditures and
restrictions on the payment of dividends, among others. The Revolver matures
in June 1999.
 
  During August 1997, PRA GmbH secured a line of credit facility providing for
aggregate borrowings up to DM 1,000,000 (approximately $542,000). The facility
accrues interest at a rate of 7.75 percent per annum on all outstanding
borrowings and is secured by the accounts receivable of PRA GmbH. The line of
credit facility has no expiration date.

SELLER NOTES PAYABLE
 
  In conjunction with the IMTCI acquisition (see Note 2), the Company issued
notes payable (the "Seller Notes") in the amounts of approximately $4,300,000
and $1,000,000 to the former owners of IMTCI. The $4,300,000 note matures in
April 2001 and is payable in quarterly installments beginning on October 1,
1997. The $1,000,000 note matures in April 2000 and is payable in 3 annual
installments of $333,333. The Seller Notes are subordinated to the Company's
long-term debt, the line of credit, and the Revolver. Interest accrues monthly
and is payable quarterly, at 8.33 percent per annum. In the event of an
initial public offering, the Seller Notes are convertible, at the option of
the holders, into common stock of the Company, using the initial public
offering price. The holders of the Seller Notes have given notice to the
Company that they elected not to convert the Seller Notes into common stock of
the Company.
 
7. INCOME TAXES:
 
  The Company accounts for income taxes under SFAS No. 109, "Accounting for
Income Taxes." SFAS No. 109 requires the determination of deferred tax assets
and liabilities based on the difference between the financial statement and
income tax bases of assets and liabilities, using enacted tax rates in effect
for the year in which the differences are expected to reverse. The measurement
of a deferred tax asset is adjusted by a valuation allowance, if necessary, to
recognize tax benefits only to the extent that, based on available evidence,
it is more likely than not that they will be realized.
 
  The provision for income taxes was as follows:

  In determining the extent to which a valuation allowance for net deferred
tax assets is required, the Company evaluates all available evidence including
projections of future taxable income, carryback opportunities, and other tax
planning strategies. During 1996, the valuation allowance for deferred tax
assets decreased by approximately $289,000. This was the result of the
utilization of previously unrecognized deferred tax assets. The remaining
valuation allowance relates primarily to foreign net operating losses as to
which the Company is unable to make a judgement about the likelihood of
realization.     
 
8. REDEEMABLE CONVERTIBLE PREFERRED STOCK AND COMMON STOCK WARRANTS:
 
SERIES A, REDEEMABLE, CONVERTIBLE, PREFERRED STOCK
 
  In October and November 1996, the Company issued 1,658,082 shares of Series
A Preferred Stock for approximately $19,371,000. The issuance of the Series A
Preferred Stock was recorded net of approximately $518,000 in stock issuance
costs.
 
  The Series A Preferred Stock may be automatically or electively converted or
mandatorily redeemed upon the occurrence of an Extraordinary Event, Liquidity
Event, or the passage of time.
 
  An Extraordinary Event occurs upon (1) a merger or consolidation with
another entity, (2) a reorganization or recapitalization, (3) an initial
public offering, or (4) disposition of substantially all of the Company's
assets.

<PAGE>
 
                            PRA INTERNATIONAL, INC.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  If an Extraordinary Event results or is expected to result in a cumulative
internal rate of return to the Series A Preferred stockholders of at least 33
percent, that Extraordinary Event shall be deemed a Liquidity Event. The
Company may pay some or all of the accrued Series A Preferred Stock dividends
to the holders to achieve a Liquidity Event. For an initial public offering to
qualify as a Liquidity Event, net proceeds from the offering must equal or
exceed $25 million. The Series A Preferred stockholders' have waived the
minimum investment return and minimum net proceeds requirements necessary for
an initial public offering to qualify as a Liquidity Event provided that an
initial public offering closes prior to January 31, 1998.
 
  Upon the occurrence of an Extraordinary Event that is not a Liquidity Event,
the Company shall issue to the Series A Preferred stockholders additional
warrants with the right to purchase common stock of the Company for a price of
$.01 per warrant. The number of warrants to be issued in such instances shall
be sufficient based on the fair value of the Company's common stock at such
time, and when added to the original purchase price of the Series A Preferred
Stock, to result in an internal rate of return to the Series A Preferred
stockholders of not less than 33 percent, including all accrued dividends paid
in cash or additional shares of stock. In no case, however, shall the number of
shares of common stock issuable pursuant to such warrant exceed 642,831.
 
 Automatic Conversion
 
  Upon the closing of an initial public offering, the merger, or the sale of
the Company prior to November 1, 1998, that qualifies as a Liquidity Event, all
outstanding shares of Series A Preferred Stock shall automatically convert into
common stock. Each share of Series A Preferred Stock shall be converted to
common stock of the Company based on a ratio defined in the stock purchase
agreement. The number of shares originally issued is subject to future
adjustment to prevent dilution of the Series A Preferred stockholders'
proportionate interests. The conversion ratio as of June 30, 1997, was 1.97-
for-one.
 
  If a Liquidity Event occurs, all accrued dividends on the Series A Preferred
Stock shall be forfeited.
 
 Optional Conversion
 
  Each share of Series A Preferred Stock is convertible, at the option of the
holder, into common stock of the Company determined in proportion to the ratio
of $11.68, the issuance price, to the Conversion Price per share, as defined.
Additionally, upon conversion, the Company shall issue an additional number of
shares of common stock to the holder of the converted Series A Preferred Stock
equal to the amount of accrued and unpaid dividends divided by the Conversion
Price then in effect, but only if the holders have not achieved the prescribed
33 percent internal rate of return.
 
 Redemption Features
 
  The Series A Preferred Stock is redeemable, at the option of the holders,
upon the occurrence of an Extraordinary Event that is not a Liquidity Event. In
the event of such an occurrence, the Series A Preferred Stock can be redeemed
at a per share price equal to the Conversion Price, as defined, including all
accrued and unpaid dividends. The Conversion Price as of June 30, 1997,
excluding accrued dividends, was $11.68, which was equal to the issuance price.
 
  Upon the occurrence of a Liquidity Event after November 1, 1998, the Series A
Preferred Stock can be redeemed at a price equal to the Conversion Price as of
the date of the Liquidity Event, plus any accrued and unpaid dividends.
 
  To the extent that any Series A Preferred Stock remains outstanding as of
October 11, 2001, the holders of the Series A Preferred Stock may redeem their
shares in three equal annual installments beginning on that date,
 
                                      F-58
<PAGE>
 
                            PRA INTERNATIONAL, INC.
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
at a price equal to the Conversion Price, plus all accrued and unpaid
dividends. The difference between the carrying value of the Series A Preferred
Stock and its redemption value is being accreted over the period to the
earliest date upon which the Series A Preferred Stock may be redeemed, not
withstanding the occurrence of an Extraordinary Event, using the effective
interest method.
 
DIVIDENDS
 
  The Series A Stock carries a cumulative dividend, which accrues quarterly, at
a rate of 9 percent per annum. Accrued dividends of approximately $344,000 and
$1,218,000 have been included in the carrying value of the Preferred Stock as
of December 31, 1996, and June 30, 1997, respectively. If the offering
contemplated by this prospectus is consummated and closes prior to January 31,
1998, all of the accrued dividends on the Series A Preferred Stock will be
forfeited.
 
  For any preferred stock not redeemed as of October 11, 2001, dividends shall
be paid at two thirds and one-third of the original amounts for the years ended
October 10, 2002 and 2003, respectively. No further dividends will accrue on
the preferred stock after October 10, 2003.
 
 Voting Rights
 
  Each share of preferred stock shall entitle the holder to the number of votes
equal to that which would exist if the preferred stock were converted into
common stock as of the date of any voting action.
 
 Liquidation Preference
 
  In the event of liquidation, dissolution, or winding up of the Company, the
holders of each share of preferred stock are entitled to redeem their shares at
an amount equal to the Conversion Price and all accrued and unpaid dividends.
 
REDEEMABLE COMMON STOCK WARRANTS
 
  In November 1994, the Company entered into an agreement with an outside
investor whereby the Company received $1,000,000 in cash in exchange for junior
subordinated debentures, preferred stock, and a warrant. The Company issued
105,419 shares of Class E convertible preferred stock at $2.37 per share, or
$250,000. The Class E preferred stock was convertible into common stock. The
Company also issued the investor a warrant (the "1994 Warrant") for the
purchase of 472,272 shares of common stock at a purchase price of $1.06 per
share. The Class E preferred stock was converted into common stock in 1996.
 
  The original agreement stipulated certain put and call provisions whereby the
investor had the option to require the Company to purchase, and the Company had
the option to require the investors to sell to the Company, the preferred stock
and the common stock underlying the warrant. The purchase price, or put value,
was the fair value of the common stock at the time of redemption. The estimated
redemption value of the preferred stock and the 1994 Warrant was accreted until
October 1996, at which time the preferred stock was converted to common stock
and the 1994 Warrant was amended to remove the put and call provisions.
 
  The 1994 Warrant can be exercised at any time until its termination date of
November 2001. The warrant agreement originally contained certain antidilution
rights whereby the 1994 Warrant might be adjusted to ensure that the outside
investor maintained a certain percentage of the Company on a fully diluted
basis. In October 1996, these antidilution rights were amended and removed. In
August 1997, approximately 236,136 shares of common stock were issued pursuant
to the 1994 Warrant.
 
  In August 1995, the Company entered into an agreement with a different
outside investor whereby the Company received $2,000,000 in cash in exchange
for a senior subordinated note payable and a warrant (the
 
                                      F-59

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
"1995 Warrant") to purchase 231,077 shares of common stock. The 1995 Warrant
had an exercise price of $.005 per share. The Company originally allocated
$329,095 of the senior subordinated note payable proceeds to the 1995 Warrant.
The 1995 Warrant could be exercised at any time until its termination date of
September 30, 2000. The warrant agreement stipulated certain put provisions
whereby the investor had the option to require the Company to purchase the
common stock underlying the 1995 Warrant. The estimated redemption value of
the 1995 Warrant was accreted until October 1996, at which time the 1995
Warrant was amended to remove the put provision. In April 1997, the 1995
Warrant was exercised in full and the Company issued 231,077 shares of common
stock to its holder.
 
9. STOCKHOLDERS' DEFICIT:
       
  In 1996, the holders of Class D and Class F preferred stock converted their
shares into shares of common stock in conjunction with the Recapitalization
discussed in Note 1.
 
STOCK REPURCHASE
 
  During October 1996, the Company repurchased 1,545,540 shares of outstanding
common stock from certain investors and employees for approximately
$9,172,000. Approximately $633,000 of this amount was expensed as compensation
as certain of the shares were repurchased immediately succeeding the exercise
of employee stock options. The repurchased shares have been recorded, net of
compensation expense discussed above, as treasury stock in the accompanying
consolidated financial statements.
 
STOCK DISTRIBUTION
 
  In 1996, the Company issued 206,986 shares of common and preferred stock to
certain common and preferred stockholders pursuant to anti-dilution protection
afforded those stockholders in their original stock purchase agreements.
 
STOCKHOLDERS' AGREEMENT
 
  Certain stockholders of the Company are party to a Stockholders' Agreement
which affords the Series A Preferred stockholders anti-dilution protection and
provides the Company and the Series A Preferred stockholders an option to
purchase any outstanding shares offered for sale by other stockholders in the
event of certain occurrences. The purchase price is the then fair market value
of the common stock. These purchase provisions will be terminated in
connection with the initial public offering.
 
SHORT-FORM STOCKHOLDERS' AGREEMENT
 
  The Company and certain optionholders are party to an agreement that
requires the Company to repurchase, in the event of death of the holder, any
stock options or common shares then outstanding at the then fair market value
of the Company's common stock. The agreement also provides the Company with
the option to repurchase any stock options or shares held at the then fair
market value in the event of certain other occurrences. There were no shares
of common stock outstanding as of December 31, 1996, or June 30, 1997, which
were subject to the repurchase provisions. The repurchase provisions will be
terminated in connection with the initial public offering.
 
10. STOCK OPTIONS:
 
  Options generally vest over a four-year period and are exercisable over a
ten-year period from the date of grant. As of June 30, 1997, 1,001,253 shares
were available for the issuance of stock options. As of June 30, 1997, 623,361
options to purchase shares of common stock were exercisable, with a weighted
average exercise price of $0.63.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  The Company generally grants stock options with exercise prices at least
equal to the then fair market value of the Company's common stock, as
determined by the Board of Directors or an independent appraisal. Any
difference between the fair value of the stock and the exercise price is
recorded as compensation expense over the vesting period of the option. During
1996 and the six months ended June 30, 1997, the Company recorded compensation
expense of approximately $11,000 and $22,000, respectively, for options whose
exercise price was less than the then fair market value of the common stock at
the date of grant, as determined by an independent appraisal.

  The Company accounts for employee stock options using the method of
accounting prescribed by Accounting Principles Board Opinion ("APB") No. 25,
"Accounting for Stock Issued to Employees." Under APB No. 25, compensation
expense is recorded for the difference, if any, between the fair market value
of the common stock at the date of the stock option grant and the exercise
price of the stock option. Effective January 1, 1996, the Company adopted SFAS
No. 123, "Accounting for Stock-Based Compensation," by making the required
footnote disclosures discussed below. Had compensation cost been determined
based on the stock's fair market value at the grant dates for awards under the
Company's stock option plan in accordance with SFAS No. 123, pro forma net
income (loss) available to common stockholders and pro forma net income (loss)
available per share would have been reduced to the amounts for the years
indicated below:

EMPLOYMENT CONTRACTS
 
  On or after October 11, 1996, the Company entered into employment contracts
with certain officers and key employees with annual remuneration ranging from
$115,000 to $175,000. The employment contracts expire in various years through
2000. As of June 30, 1997, remaining aggregate annual payments under such
agreements approximated $433,000, $796,000, $350,000 and $102,000 during 1997
through 2000. In the event of disability, the covered employees will be
entitled to severance payments up to one year's salary. The contracts
also contain certain repurchase provisions in the event of death or termination
without cause covering future incentive stock option grants and shares acquired
pursuant to future incentive stock option grants. As of December 31, 1996, and
June 30, 1997, no shares had been issued pursuant to such option grants. The
repurchase price is the then fair market value of the common stock. The
repurchase provisions will be terminated in connection with the initial public
offering.
 
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.

  Section 145 of the General Corporation Law of Delaware empowers a Delaware

to the extent and under the circumstances set forth therein.
 
  The Restated Certificate of Incorporation and the By-Laws of the Registrant,

provide for advancement of expenses and indemnification of officers and
directors of the Registrant and certain other persons against liabilities and
expenses incurred by any of them in certain stated proceedings and under
certain stated conditions to the fullest extent permitted by law.
 
  The Registrant intends to maintain insurance for the benefit of its

including liabilities under the securities laws.
 
  Section 7 of the Underwriting Agreement between the Registrant and the

The Underwriting Agreement also provides that the Underwriters shall similarly

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
   
  In November 1994, pursuant to a $1,000,000 venture capital financing with
Virginia Capital, L.P. ("Virginia Capital"), successor in interest to Vedcorp,
L.C., Associates issued (i) a 12.5% subordinated debenture originally due
December 31, 1998 in the original principal amount of $750,000, (ii) a warrant
to purchase shares of Class C Common Stock of Pharmaceutical Research
Associates, Inc., a Virginia corporation ("Associates") constituting 6.67% of
the common stock of Associates on a fully-diluted basis, for an aggregate
exercise price of $500,000 and (iii) 53,512 shares of Class E Preferred Stock
of Associates. The issuance and sale of such securities were made in reliance
upon Section 4(2) of the Securities Act. In August 1997, the     
 
                                     II-1
<PAGE>
 
   
debenture was repaid in full and the warrant, as subsequently modified, was
exercised in part for 236,136 shares of Common Stock.     
   
  In August 1995, pursuant to a venture capital financing with Sirrom
Investments, Inc. ("Sirrom"), successor in interest to Sirrom Capital
Corporation, Associates issued (i) a secured promissory note in the original
principal amount of $2 million due August 10, 2000, which is secured by a
subordinated blanket lien on Associates' assets and (ii) a stock purchase
warrant exercisable for shares of Class C Common Stock of Associates
constituting 6% of the common stock of Associates on a fully-diluted basis,
for an aggregate exercise price of $.01 per share, which, as subsequently
modified, was exercised in full in April, 1997. In connection with this
transaction, Virginia Capital's warrant was replaced by a warrant to purchase
shares of Class C Common Stock of Associates constituting 12.27% of the common
stock of Associates on a fully-diluted basis, for an aggregate exercise price
of $500,000. The issuance and sale of such securities were made in reliance
upon Section 4(2) of the Securities Act.     
   
  On February 7, 1996, Associates made a personal loan to Associates' founder,
Raymond J. Rugloski, in the amount of $500,000. This loan was financed from
the proceeds of its sale in December 1995/January 1996 of 76,830 shares of
Class F Preferred Stock of Associates at a price per share of $6.5080,
representing, in the event of their conversion into common stock of
Associates, 4% of the common stock of Associates on a fully-diluted basis, to
Virginia Capital, Sirrom and Messrs. Earle Martin, James Powers, Joachim
Vollmar and W. Bain MacLachlan. The issuance and sale of such securities were
made in reliance upon Section 4(2) of the Securities Act.     
   
  In September 1996, as a result of anti-dilution protections afforded Raymond
Rugloski and his wife, Carolyn Rugloski, Sheridan Snyder, Virginia Capital,
Sirrom and the other Class F Preferred Stockholders of Associates, 44,925
shares of Class A Common Stock were issued to the Rugloskis, 4,992 additional
shares of Class B Common Stock were issued to Mr. Snyder, the amount of shares
of Class C Common Stock of Associates for which Virginia Capital's and
Sirrom's warrants were exercisable was increased by 9,479 and 3,792 shares,
respectively, and the Class F Preferred Stockholders of Associates received an
additional 5,482 shares of Class F Preferred Stock. The issuance and sale of
such securities were made in reliance upon Section 4(2) of the Securities Act.
    
  (All of the foregoing references to the share numbers of capital stock of
Associates are on an as-issued basis and do not reflect the effect of the
stock split on the shares of Common Stock received in respect thereof pursuant
to the agreement and plan of share exchange referred to below.)
   
  In October 1996, the Company completed a recapitalization and
reorganization. First, the Company became the holding company of Associates,
pursuant to an agreement and plan of share exchange between the Company and
Associates. Under that agreement and plan, all outstanding shares and all
options and warrants to purchase shares of each class of common and preferred
stock of Associates were acquired by the Company in exchange for an identical
number of outstanding shares and options and warrants to purchase shares of
Common Stock. The Company then sold, for an aggregate purchase price of
approximately $19.1 million (or approximately $5.93 per share after giving
effect to their conversion to Common Stock upon the closing of the Offering),
1,631,548 shares of its Series A Preferred Stock to certain affiliates of The
Carlyle Group, along with a related warrant agreement providing for the
issuance of warrants to purchase an identical number of shares of Common Stock
upon the occurrence of certain circumstances. In November 1996, Virginia
Capital purchased 26,534 shares of Series A Preferred Stock and a related
warrant agreement for an aggregate purchase price of approximately $310,000
(or approximately $5.93 per share). These issuances of securities were exempt
from registration under the Securities Act by virtue of Rule 506 of Regulation
D promulgated under the Securities Act and Section 4(2) thereof.     
 
  In April 1997, the Company acquired the capital stock of International
Medical Technical Consultants, Inc., a Kansas corporation ("IMTCI") from its
stockholders. Of the aggregate purchase price of approximately $15.3 million
paid to IMTCI's stockholders, $2 million was paid in the form of 143,272
shares of Common Stock at a price of $13.96 per share after giving effect to
the Company's recent stock split. This issuance of securities by the Company
was exempt from registration under the Securities Act by virtue of Section
4(2) thereof.

ITEM 17. UNDERTAKINGS.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions described in Item 14 above, or
otherwise, the Registrant has been advised that, in the opinion of the
Securities and Exchange Commission, such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other
than the payment by the Registrant of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of
any action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of competent jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.
 
  The undersigned Registrant hereby undertakes:
 
    (1) That for purposes of determining any liability under the Securities
  Act, the information omitted from the form of prospectus filed as part of
  this registration statement in reliance upon Rule 430A and contained in a
  form of prospectus filed by the Registrant pursuant to Rule 424 (b)(1) or
  (4) or 497(h) under the Securities Act shall be deemed to be part of this
  Registration Statement as of the time it was declared effective.
 
    (2) That for purposes of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of prospectus shall
  be deemed to be a new registration statement relating to the securities
  offered therein, and the offering of securities at that time shall be
  deemed to be the initial bona fide offering thereof.
 
    (3) To provide to the Underwriters at the closing specified in the
  Underwriting Agreement certificates in such denominations and registered in
  such names as required by the Underwriters to permit prompt delivery to
  each purchaser.

         --------                                                               
employment in the position of President, with appropriate title, rank, status
and responsibilities as determined from time to time by Employer upon the terms
and conditions hereinafter set forth.

     2.  Term.  The period of employment under this Agreement shall begin on the

date of this Agreement (the "Effective Date"), and shall end on November 1, 1998
(the "First Termination Date"), unless sooner terminated pursuant to Section 7
hereof.  After the First Termination Date, employment hereunder  shall be deemed
to be renewed automatically, upon the same terms and conditions, for

                                     - 1 -
<PAGE>
 
successive periods of one year each, until either party, at least ninety (90)
days prior to the expiration of the First Termination Date or any successive
term, as applicable, shall give written notice to the other of a determination
not to renew such employment.  Notwithstanding the foregoing, Employee's
employment hereunder shall be terminable at any time, and from time to time, in
accordance with the provisions of Section 7 of this Agreement. Subject to
Section 7(d) of this Agreement, the period during which (a) Employee is employed
under the terms of this Agreement and (b) this Agreement is in force (other than
with respect to the provisions that survive termination of this Agreement),
shall be known hereafter as the "Term".

     3.  Duties.
         ------ 

         (a)  During the Term, Employee agrees to use his best efforts in the
business of Employer and to devote his full time, skill, attention and energies
to the business of Employer, and shall not, during the Term, be engaged in any
other business activity which shall be competitive with the business of Employer
or which may (i) interfere with Employee's ability to discharge his
responsibilities to Employer, or (ii) detract from the business of Employer.
The Board of Directors of Employer (the "Board") shall have the power to
determine the specific duties that shall be performed by Employee and the means
and manner by which those duties shall be performed.

         (b)  In furtherance of the restrictions on the activities of Employee
set forth in Section 3(a) above, during the Term, Employee agrees:

         (i)  not to work either on a part-time or independent contracting basis
for any other company, business or enterprise without the prior written consent
of the Board; and

                                     - 2 -
<PAGE>
 
         (ii) not to serve on the board of directors or comparable governing
body of any other material business, civic or community corporation or similar
entity without the prior written consent of the Board (excluding those boards of
directors on which Employee serves as of the date of this Agreement, which
boards, if any, are listed on Exhibit A hereto).

         (c)  Employee agrees to use his reasonable efforts to impart his skill
and knowledge relating to the business of Employer to such individuals as are
designated by Employer, and to train such individuals in the aspects of the
business with which Employee is familiar. In addition, at the request of
Employer and without additional compensation, Employee shall use his best
efforts to record and document his knowledge relating to the business of
Employer.

     4.  Base Salary, Increases, Benefits, Expenses.  For all services rendered
         ------------------------------------------                            
by Employee under this Agreement and subject to Section 7 below, during the
Term, Employer shall provide Employee with the following:

         (a)  Commencing on the Effective Date, Employer shall pay to Employee,
in equal bi-monthly installments, a base salary of $125,000 per year.

         (b)  Employee shall be eligible for salary increases, which may be
based on performance and/or cost-of-living factors, as determined under the
provisions of any salary policy of Employer that is generally applicable to
Employer's employees, provided that any such increases shall be reviewed and
approved in advance by the Compensation Committee of the Board (the
"Compensation Committee"), and Employee shall be entitled to such other
increases in compensation as are otherwise imposed by the Compensation
Committee, in its discretion, from time to time.

                                     - 3 -
<PAGE>
 
         (c)  Employee shall participate in Employer's 1996 Bonus Plan, as such
1996 Bonus Plan currently exists on the date of this Agreement.

         (d)  Employee shall participate in Employer's standard benefits
programs, which presently include health, life and disability insurance, as well
as those additional benefits (the "Additional Benefits") currently offered to
Employer's executive staff, including additional life and disability insurance,
health club membership and monthly car allowance. It is agreed that the nature
and amount of the Additional Benefits, if any, shall be determined from time to
time by the Compensation Committee, in its discretion. Employer may, at its
election, maintain policies of life and disability insurance on Employee, with
Employer or an affiliate of Employer as beneficiary, and Employee shall
cooperate as necessary to obtain such policies and to keep them in force.
Employee shall be entitled to a total of twenty (20) days of paid vacation per
year. Employee shall be covered by the holiday policy of the Employer, and,
unless inconsistent with applicable law, by any other pension or retirement
plan, disability benefit plan or any other benefit plan or arrangement of
Employer (other than a medical or life insurance plan) presently or hereafter
existing for the benefit of officers or employees of Employer generally, and
determined by the Compensation Committee to be applicable to Employee.

         (e)  Subject to such conditions as Employer may from time to time
determine, Employer shall pay or reimburse Employee for reasonable expenses
incurred by Employee in connection with the business of Employer and the
performance of Employee's duties hereunder.

         (f)  It is understood and agreed that the Compensation Committee will
meet quarterly to review compensation matters of Employer, and will (on at least
an annual basis) set all

                                     - 4 -
<PAGE>
 
annual bonus targets, salary increases and benefits to which Employee shall be
entitled to participate.

         (g)  It is the intention of Employer to have the Compensation Committee
recommend to the Board of Directors (the "PRADE Board") of PRA International,
Inc., a Delaware corporation and the parent company of Employer ("PRADE"), to
create, shortly after the date of this Agreement, an incentive based option plan
for key employees of Employer (the "ISO Plan").  It is expected that the ISO
Plan will consist of options for common stock of PRADE and will have key terms,
subject to alteration and amendment in the sole discretion of the PRADE Board in
consultation with the Compensation Committee, substantially similar to those set
forth on Exhibit B hereto as well as those contemplated by Section 8 of this
Agreement.  At such time as the ISO Plan is created, Employee shall be entitled
to participate therein.

     5.  Confidential Information and Certain Property Matters.
         ----------------------------------------------------- 

         (a)  Employee hereby acknowledges that, in the course of his employment
under this Agreement, he will be given access to or otherwise will come into
contact with and/or will possess, and that with respect to Employer's business
he already possesses, information, knowledge, contacts and experience relating
to the businesses, operations, properties, assets, liabilities and financial
condition of Employer and the markets and industries in which it operates,
including, without limitation, information relating to business plans and ideas,
trade secrets, intellectual property, know-how, formulas, processes, research
and development, methods, policies, materials, results of operations, financial
and statistical data, personnel data and customers in and related to the markets
and industries in which Employer operates (the "Confidential Information"),
which are considered by Employer to be valuable, secret, confidential and
proprietary.  Employee hereby

                                     - 5 -
<PAGE>
 
acknowledges and agrees that the Confidential Information is valuable, secret,
confidential and proprietary to Employer, and hereby undertakes and agrees that
he shall not, at any time (whether during or after the expiration of the Term),
or for any purpose, make public, disclose, divulge, furnish, release, transfer,
sell or otherwise make available to any person any of the Confidential
Information, or otherwise use any of the same or allow any of the same to be
used for any purpose including, but not limited to, contacting for any purpose
the personnel, customers or suppliers of Employer, other than as may be
permitted to Employee under this Agreement.  Notwithstanding the foregoing,
Employee may, without violating this Section 5(a), disclose Confidential
Information if (i) such disclosure is required to comply with a valid court
order or any administrative law order or decree, (ii) Employee gives Employer
advance written notice of the required disclosure so that Employer may, if it
wishes, seek an appropriate protective order and (iii) Employee, in any event,
requests that any disclosed information be afforded confidential treatment, to
the greatest extent possible.

         (b)  Employee hereby agrees to promptly and fully disclose to Employer
all Inventions made or conceived by him that would be deemed applicable, useful
or otherwise beneficial to or in respect of, the current business of Employer,
in whole or in part, during his employment with Employer. For the purposes of
this Agreement, "Inventions" include, but are not limited to, customer list
compilations, machinery, apparatus, products, processes, results of research and
development (including without limitation results that constitute trade secrets,
ideas and writings), computer hardware, information systems, software (including
without limitation source code, object code, documentation, diagrams and flow
charts) and any other discoveries, concepts and ideas, whether patentable or not
(including without limitation processes, methods, formulas, and techniques, as
well as improvements thereof or know-how related thereto, concerning any present
or prospective business

                                     - 6 -
<PAGE>
 
activities of Employer).  Any and all Inventions shall be the absolute property
of Employer or its designees, and Employee acknowledges that he shall have no
interest whatsoever in such Inventions.  At the request of Employer and without
additional compensation, Employee (i) shall make application in due form for
United States letters patent and foreign letters patent on such Inventions, and
shall assign to Employer all his right, title and interest in such Inventions,
(ii) shall execute any and all instruments and do any and all acts necessary or
desirable in connection with any such application for letters patent or in order
to establish and perfect in Employer the entire right, title and interest in
such Inventions, patent applications or patents and (iii) shall execute any
instruments necessary or desirable in connection with any continuations,
renewals or reissues thereof or in the conduct of any related proceedings or
litigation.  Except as authorized by Employer in writing, Employee shall not
disclose, directly or indirectly, to any person other than Employer, any
information relating to any Invention or any patent application relating
thereto.

         (c)  Employee hereby acknowledges and agrees that the work performed by
Employee pursuant to his employment by Employer will be specifically ordered or
commissioned by Employer, and that such work shall be considered a "work for
hire" as defined in the Copyright Revision Act of 1976 (the "Act"), granting
Employer full ownership to the work and all rights comprised therein.  Should
any work not fall within the definition of a "work for hire" as set forth in
such Act, Employee hereby transfers and assigns to Employer full ownership of
the copyright to the work and all rights comprised therein.  Employee shall sign
all applications for registration of such copyright as are requested by
Employer, and shall sign all other writings and instruments and perform all
other acts necessary or desirable to carry out the terms of this Agreement.

<PAGE>
 
     6.  Covenant Not to Compete.  (a)  Employee agrees that during the Term and
         -----------------------                                                
for a period of two years thereafter (the "Noncompetition Period"), he shall not
directly or indirectly own, manage, operate, join, advise, consult, control or
participate in the ownership, management, operation or control of, or be
connected in any manner with, any business under any name similar to the name of
Employer or any other person whose principal business is (or the principal
business of any of its affiliates is) competitive with Employer or who proposes
to engage in a business competitive with Employer, or in any department or
division of any other person where such department or division is competitive
with Employer (where the nature of Employer's business is measured (i) if the
competitive act in question occurs during the Term, at the time the competitive
act in question is made by Employee, and (ii) if the competitive act in question
occurs after the Term, at the time Employee's employment is terminated
hereunder).  During the Noncompetition Period, Employee agrees that he shall not
offer to any person any services that compete with or are substantially similar
to those provided by Employer (where the nature of Employer's business,
including the services provided by Employer, are measured (1) if the offer is
made during the Term, at the time the offer is made by Employee, and (2) if the
offer is made after the Term, at the time Employee's employment is terminated
hereunder).

         (b)  Employee agrees that he shall not engage in unfair competition
with Employer during the Noncompetition Period.

         (c)  Employee agrees that he shall not, during the Noncompetition
Period (after the Term), other than on behalf of Employer and consistent with
his duties as an employee of Employer, directly or indirectly solicit the trade
of, or trade with, any person who is a client, customer or supplier of Employer
(where all such clients, customers and suppliers are measured at the time

                                     - 8 -
<PAGE>
 
Employee's employment is terminated hereunder) unless Employee receives the
prior written consent of the Board to do so.

         (d)  Employee agrees that he shall not, during the Noncompetition
Period (after the Term), directly or indirectly, solicit or induce (or attempt
to solicit or induce) to leave the employ of Employer for any reason whatsoever,
or hire, any person who (i) was employed by Employer within one year prior to
the time of the act of solicitation or inducement, or (ii) is employed by
Employer at the time of the act of solicitation or inducement.

         (e)  During and after the Term, Employee agrees not to disparage
Employer, the parent of Employer, or any of the subsidiaries or affiliates of
Employer. During and after the Term, Employer agrees not to disparage the
character of Employee.

         (f)  Employee hereby specifically acknowledges and agrees that the
provisions of this Section 6 are reasonable and necessary to protect the
legitimate interests of Employer, and that Employee desires to agree to the
provisions of this Section 6.  In the event that any of the provisions of this
Section 6 should ever be held to exceed the time, scope or geographic
limitations permitted by applicable law, it is hereby declared to be the
intention of the parties hereto that such provision be reformed to reflect the
maximum time, scope and geographic limitations that are permitted by such law.

         (g)  Employee hereby acknowledges and agrees for himself, and for any
person participating with him in any breach or threatened breach of this 
Section 6 (the "Other Person"), that, owing to the special, unique and
extraordinary nature of the matters covered by this Section 6, in the event of
any breach or threatened breach by Employee or the Other Person of any of the
provisions hereof, Employer would suffer substantial and irreparable injury,
which could not be fully compensated by

                                     - 9 -
<PAGE>
 
monetary award alone, and Employer would not have adequate remedy at law.
Therefore, Employee agrees that, in such event, Employer shall be entitled to
temporary and/or permanent injunctive relief against him and any such Other
Person, without the necessity of proving actual damages or of posting bond to
enforce any of the provisions of this Section 6, and he hereby waives for
himself and for any such Other Person the defenses, claims, or arguments that
the matters are not special, unique, and extraordinary, that Employer must prove
actual damages, and that Employer has an adequate remedy at law.

         (h)  Employee further agrees that the rights and remedies described in
this Section 6 are cumulative and shall be in addition to and not in lieu of any
other rights and remedies otherwise available under this Agreement, or at law or
in equity, including but not limited to monetary damages.

     7.  Termination.
         ----------- 

         (a)  Basic Termination.  In addition to the termination provisions 
              -----------------
set forth in Section 7(b) and Section 7(c) hereof, the Term shall terminate
pursuant to the applicable provisions of Section 2 hereof and immediately upon
the death of Employee. Upon termination of the Term under the applicable
provisions of Section 2 hereof or upon the death of Employee, Employer shall
have no further obligation to Employee except as set forth in Section 8 hereof.

         (b)  Termination By Employer.  The Term may be terminated by Employer
              -----------------------
under the following circumstances (in each case, upon such termination, Employer
shall have no further obligation to Employee except as set forth in Section 8
hereof):

         (i)  Disability.  If during the Term, Employee   shall be prevented 
              ----------
from performing his duties for a continuous

                                     - 10 -
<PAGE>
 
period of one hundred and eighty (180) days by reason of disability which
renders Employee physically or mentally incapable (excluding infrequent and
temporary absences due to illness) of performing substantially all of his duties
under this Agreement, Employer may terminate Employee's employment hereunder. If
after a period of disability commences (but prior to termination of Employee's
employment), Employee returns to work for a period of at least twenty (20)
consecutive work days, the period of disability shall be deemed to terminate and
not be counted towards any period of subsequent disability. For purposes of this
Agreement, Employer, upon the advice of a qualified and impartial physician,
shall determine whether Employee has become physically or mentally incapable of
performing substantially all of his duties under this Agreement. Employer shall
give Employee (or his guardian, as applicable) thirty (30) days' written notice
of termination of the Term under this Section 7(b)(i).

          (ii)  For Good Cause. Employer may terminate Employee's employment at
                --------------
     any time for Good Cause (as defined below), by giving reasonable notice
     under the circumstances to Employee. "Good Cause" shall include, without
     limitation, (A) a material breach of this Agreement by Employee (where
     Employee fails to cure such breach within five (5) days after being
     notified in writing by Employer of such breach), (B) Employee's failure to
     perform his assigned duties without an excuse that is reasonably acceptable
     to Employer, (C) Employee engages in an act (or causes an act) that has a
     material adverse impact on the reputation, business, business relationships
     or financial condition of Employer, (D) the conviction of Employee of a
     felony or any crime involving moral turpitude, fraud or misrepresentation,
     (E) misappropriation or embezzlement by Employee of funds or assets of
     Employer, and (F) Employee's willful refusal to


                                    - 11 -
<PAGE>
 
     perform specific directives of the Board which are consistent with the
     scope, ethics and nature of Employee's duties and responsibilities
     hereunder. Notwithstanding the foregoing, "Good Cause" shall not include a
     situation whereby Employer asks Employee to relocate to another city and
     Employee declines to do so. Termination by Employer for Good Cause
     hereunder based on a material breach of this Agreement or for other
     wrongful acts committed by Employee against Employer, shall not abrogate
     the rights and remedies of Employer in respect of the breach or wrongful
     act giving rise to such termination.

          (c)  Termination by Employee. The Term may be terminated by Employee
               -----------------------
upon thirty (30) days' written notice given to Employer after a material breach
hereof by Employer (where Employer fails to cure such breach within five (5)
days after being notified in writing by Employee of such breach). Termination by
Employee hereunder shall not abrogate the rights and remedies of Employee in
respect of the breach giving rise to such termination. Upon termination by
Employee following a material breach by Employer, Employee shall have no further
duties or obligations to Employer under this Agreement (except as contemplated
by Section 7(d) below).

          (d)  Survival of Sections.  It is agreed that notwithstanding anything
               --------------------                                             
contained in this Agreement to the contrary, Sections 5, 6, the applicable
provisions of 7(b)(ii), 8 and 9 of this Agreement shall survive termination of
the Term.

     8.   Payments by, Obligations of, and Events Affecting the Respective
          ----------------------------------------------------------------
Parties in Event of Termination.
- ------------------------------- 

          (a)  Should the Term terminate under Section 7(a) of this Agreement

                        (B)  severance payments equal to the sum of (y) six
          months base salary (as it would normally be paid) plus (z) an
          additional six months base salary less the fair market value (as of
          the date on which the Term is terminated) of any options held by
          Employee under the ISO Plan which have vested and any shares held by
          Employee as a result of the exercise by Employee of vested options
          held by Employee under the ISO Plan (such fair market value to be
          determined by the Board in good faith).

                  (ii) Benefits pursuant to any of Employer's employee benefit
          plans shall be payable in accordance with the terms of the instruments
          applicable thereto.

                  (iii)  All unvested options held by Employee under the ISO
          Plan will automatically terminate (under the terms of the ISO Plan).

                  (iv)  In the event the Term is terminated due to the death of
          Employee, PRADE shall have the right, in its sole discretion (under
          the terms of the ISO Plan), to purchase from the estate of Employee
          (within ninety (90) days of the date on which the Term is terminated),
          vested options held by Employee under the ISO plan and/or any shares
          held by the estate of Employee as a result of the exercise by Employee

<PAGE>
 
          estate) of vested options held by Employee under the ISO Plan. The
          purchase price of the options and shares contemplated by this Section
          8(a)(iv) shall be the fair market value of such vested options and/or
          shares as of the date on which the Term is terminated (as determined
          by the PRADE Board in good faith).

                  (b)  Should the Term be terminated by Employer under Section
7(b)(ii) of this Agreement (for Good Cause):

                  (i)  Employee shall be entitled to receive (within fifteen
          (15) days of the date on which the Term is terminated) any and all
          accrued but unpaid base salary compensation due to Employee as of the
          date on which the Term is terminated.

                  (ii) Benefits pursuant to any of Employer's employee benefit
          plans shall be payable in accordance with the terms of the instruments
          applicable thereto.

                  (iii) All unvested options held by Employee under the ISO Plan

                  (iv) All vested options held by Employee under the ISO Plan
          that are not exercised by Employee within ninety (90) days of the date
          on which the Term is terminated, will automatically terminate (under
          the terms of the ISO Plan).

                  (c)  Should the Term be terminated by Employee under Section
7(c) of this Agreement:

                       (A) Any and all accrued but unpaid base salary
          compensation due to Employee as of the date on which the

<PAGE>
 
     Term is terminated (payable within fifteen (15) days of the date on which
     the Term is terminated); plus

               (B)  full base salary (payable monthly at the same time Employee
     would otherwise be entitled to receive such base salary if Employee were
     still employed by Employer) (y) through November 1, 1998 or (z) for a
     period of twelve (12) months after the date on which the Term is

terms of the ISO Plan).

          (iv) Within ninety (90) days of the date on which the Term is
terminated, Employee shall have the option (under the terms of the ISO Plan) to
require PRADE to repurchase (during such ninety (90) day period) vested options
held by Employee under the ISO Plan and/or shares of PRADE's common stock
previously issued pursuant to the exercise of options held by Employee under the
ISO Plan. The purchase price of the options and/or shares contemplated by this
Section 8(c)(iv) shall be the fair market value of such vested options and/or
shares as of the date on which the Term is terminated (as determined by the
PRADE Board in good faith). Notwithstanding the foregoing, the obligation of
PRADE to repurchase the options and/or shares referenced in this Section
8(c)(iv) shall only apply to the extent PRADE has funds legally and readily
available to make such repurchase (with the availability of the funds being
determined by the PRADE Board in good faith).

efforts to record and document his knowledge relating to the business of
Employer.

         (c)  Employee shall participate in Employer's 1996 Bonus Plan, as such
1996 Bonus Plan currently exists on the date of this Agreement.

         (d)  Employee shall participate in Employer's standard benefits
programs, which presently include health, life and disability insurance, as well
as those additional benefits (the "Additional Benefits") currently offered to
Employer's executive staff, including additional life and disability insurance,
health club membership and monthly car allowance. It is agreed that the nature
and amount of the Additional Benefits, if any, shall be determined from time to
time by the Compensation Committee, in its discretion. Employer may, at its

Employer or an affiliate of Employer as beneficiary, and Employee shall
cooperate as necessary to obtain such policies and to keep them in force.
Employee shall be entitled to a total of twenty (20) days of paid vacation per

unless inconsistent with applicable law, by any other pension or retirement
plan, disability benefit plan or any other benefit plan or arrangement of

existing for the benefit of officers or employees of Employer generally, and
determined by the Compensation Committee to be applicable to Employee.

         (e)  Subject to such conditions as Employer may from time to time
determine, Employer shall pay or reimburse Employee for reasonable expenses
incurred by Employee in connection with the business of Employer and the
performance of Employee's duties hereunder.

         (f)  It is understood and agreed that the Compensation Committee will
meet quarterly to review compensation matters of Employer, and will (on at least
an annual basis) set all

                                     - 4 -
<PAGE>
 
annual bonus targets, salary increases and benefits to which Employee shall be
entitled to participate.

         (g)  It is the intention of Employer to have the Compensation Committee
recommend to the Board of Directors (the "PRADE Board") of PRA International,
Inc., a Delaware corporation and the parent company of Employer ("PRADE"), to
create, shortly after the date of this Agreement, an incentive based option plan
for key employees of Employer (the "ISO Plan").  It is expected that the ISO
Plan will consist of options for common stock of PRADE and will have key terms,
subject to alteration and amendment in the sole discretion of the PRADE Board in
consultation with the Compensation Committee, substantially similar to those set
forth on Exhibit B hereto as well as those contemplated by Section 8 of this
Agreement.  At such time as the ISO Plan is created, Employee shall be entitled
to participate therein.

     5.  Confidential Information and Certain Property Matters.
         ----------------------------------------------------- 

         (a)  Employee hereby acknowledges that, in the course of his employment
under this Agreement, he will be given access to or otherwise will come into
contact with and/or will possess, and that with respect to Employer's business
he already possesses, information, knowledge, contacts and experience relating
to the businesses, operations, properties, assets, liabilities and financial

and development, methods, policies, materials, results of operations, financial
and statistical data, personnel data and customers in and related to the markets
and industries in which Employer operates (the "Confidential Information"),
which are considered by Employer to be valuable, secret, confidential and
proprietary.  Employee hereby

                                     - 5 -
<PAGE>
 
acknowledges and agrees that the Confidential Information is valuable, secret,
confidential and proprietary to Employer, and hereby undertakes and agrees that
he shall not, at any time (whether during or after the expiration of the Term),
or for any purpose, make public, disclose, divulge, furnish, release, transfer,
sell or otherwise make available to any person any of the Confidential
Information, or otherwise use any of the same or allow any of the same to be
used for any purpose including, but not limited to, contacting for any purpose
the personnel, customers or suppliers of Employer, other than as may be
permitted to Employee under this Agreement.  Notwithstanding the foregoing,
Employee may, without violating this Section 5(a), disclose Confidential
Information if (i) such disclosure is required to comply with a valid court
order or any administrative law order or decree, (ii) Employee gives Employer
advance written notice of the required disclosure so that Employer may, if it
wishes, seek an appropriate protective order and (iii) Employee, in any event,
requests that any disclosed information be afforded confidential treatment, to
the greatest extent possible.

         (b)  Employee hereby agrees to promptly and fully disclose to Employer
all Inventions made or conceived by him that would be deemed applicable, useful
or otherwise beneficial to or in respect of, the current business of Employer,
in whole or in part, during his employment with Employer. For the purposes of
this Agreement, "Inventions" include, but are not limited to, customer list
compilations, machinery, apparatus, products, processes, results of research and
development (including without limitation results that constitute trade secrets,
ideas and writings), computer hardware, information systems, software (including
without limitation source code, object code, documentation, diagrams and flow

well as improvements thereof or know-how related thereto, concerning any present
or prospective business

                                     - 6 -
<PAGE>
 
activities of Employer).   Any and all Inventions shall be the absolute property
of Employer or its designees, and Employee acknowledges that he shall have no
interest whatsoever in such Inventions.  At the request of Employer and without
additional compensation, Employee (i) shall make application in due form for
United States letters patent and foreign letters patent on such Inventions, and
shall assign to Employer all his right, title and interest in such Inventions,
(ii) shall execute any and all instruments and do any and all acts necessary or
desirable in connection with any such application for letters patent or in order
to establish and perfect in Employer the entire right, title and interest in
such Inventions, patent applications or patents and (iii) shall execute any
instruments necessary or desirable in connection with any continuations,
renewals or reissues thereof or in the conduct of any related proceedings or
litigation.  Except as authorized by Employer in writing, Employee shall not
disclose, directly or indirectly, to any person other than Employer, any
information relating to any Invention or any patent application relating
thereto.

         (c)  Employee hereby acknowledges and agrees that the work performed by
Employee pursuant to his employment by Employer will be specifically ordered or
commissioned by Employer, and that such work shall be considered a "work for
hire" as defined in the Copyright Revision Act of 1976 (the "Act"), granting
Employer full ownership to the work and all rights comprised therein.  Should
any work not fall within the definition of a "work for hire" as set forth in
such Act, Employee hereby transfers and assigns to Employer full ownership of
the copyright to the work and all rights comprised therein.  Employee shall sign
all applications for registration of such copyright as are requested by
Employer, and shall sign all other writings and instruments and perform all
other acts necessary or desirable to carry out the terms of this Agreement.

     6.  Covenant Not to Compete.  (a)  Employee agrees that during the Term and
         -----------------------                                                
for a period of two years thereafter (the "Noncompetition Period"), he shall not
directly or indirectly own, manage, operate, join, advise, consult, control or
participate in the ownership, management, operation or control of, or be
connected in any manner with, any business under any name similar to the name of
Employer or any other person whose principal business is (or the principal
business of any of its affiliates is) competitive with Employer or who proposes
to engage in a business competitive with Employer, or in any department or
division of any other person where such department or division is competitive
with Employer (where the nature of Employer's business is measured (i) if the
competitive act in question occurs during the Term, at the time the competitive
act in question is made by Employee, and (ii) if the competitive act in question
occurs after the Term, at the time Employee's employment is terminated
hereunder).  During the Noncompetition Period, Employee agrees that he shall not
offer to any person any services that compete with or are substantially similar
to those provided by Employer (where the nature of Employer's business,
including the services provided by Employer, are measured (1) if the offer is
made during the Term, at the time the offer is made by Employee, and (2) if the
offer is made after the Term, at the time Employee's employment is terminated
hereunder).

         (b)  Employee agrees that he shall not engage in unfair competition
with Employer during the Noncompetition Period.

         (c)  Employee agrees that he shall not, during the Noncompetition
Period (after the Term), other than on behalf of Employer and consistent with
his duties as an employee of Employer, directly or indirectly solicit the trade
of, or trade with, any person who is a client, customer or supplier of Employer
(where all such clients, customers and suppliers are measured at the time

                                     - 8 -
<PAGE>
 
Employee's employment is terminated hereunder) unless Employee receives the
prior written consent of the Board to do so.

         (d)  Employee agrees that he shall not, during the Noncompetition
Period (after the Term), directly or indirectly, solicit or induce (or attempt
to solicit or induce) to leave the employ of Employer for any reason whatsoever,
or hire, any person who (i) was employed by Employer within one year prior to
the time of the act of solicitation or inducement, or (ii) is employed by
Employer at the time of the act of solicitation or inducement.

         (e)  During and after the Term, Employee agrees not to disparage
Employer, the parent of Employer, or any of the subsidiaries or affiliates of
Employer. During and after the Term, Employer agrees not to disparage the
character of Employee.

         (f)  Employee hereby specifically acknowledges and agrees that the
provisions of this Section 6 are reasonable and necessary to protect the
legitimate interests of Employer, and that Employee desires to agree to the
provisions of this Section 6. In the event that any of the provisions of this
Section 6 should ever be held to exceed the time, scope or geographic
limitations permitted by applicable law, it is hereby declared to be the
intention of the parties hereto that such provision be reformed to reflect the
maximum time, scope and geographic limitations that are permitted by such law.

         (g)  Employee hereby acknowledges and agrees for himself, and for any
person participating with him in any breach or threatened breach of this Section
6 (the "Other Person"), that, owing to the special, unique and extraordinary
nature of the matters covered by this Section 6, in the event of any breach or
threatened breach by Employee or the Other Person of any of the provisions
hereof, Employer would suffer substantial and irreparable injury, which could
not be fully compensated by

                                     - 9 -
<PAGE>
 
monetary award alone, and Employer would not have adequate remedy at law.
Therefore, Employee agrees that, in such event, Employer shall be entitled to
temporary and/or permanent injunctive relief against him and any such Other
Person, without the necessity of proving actual damages or of posting bond to
enforce any of the provisions of this Section 6, and he hereby waives for
himself and for any such Other Person the defenses, claims, or arguments that
the matters are not special, unique, and extraordinary, that Employer must prove
actual damages, and that Employer has an adequate remedy at law.

         (h)  Employee further agrees that the rights and remedies described in
this Section 6 are cumulative and shall be in addition to and not in lieu of any
other rights and remedies otherwise available under this Agreement, or at law or
in equity, including but not limited to monetary damages.

     7.  Termination.
         ----------- 

         (a)  Basic Termination.  In addition to the termination provisions set
              -----------------
forth in Section 7(b) and Section 7(c) hereof, the Term shall terminate pursuant
to the applicable provisions of Section 2 hereof and immediately upon the death
of Employee. Upon termination of the Term under the applicable provisions of
Section 2 hereof or upon the death of Employee, Employer shall have no further
obligation to Employee except as set forth in Section 8 hereof.

         (b)  Termination By Employer.  The Term may be terminated by Employer
              -----------------------
under the following circumstances (in each case, upon such termination, Employer
shall have no further obligation to Employee except as set forth in Section 8
hereof):

         (i)  Disability.  If during the Term, Employee shall be prevented from
              ----------
performing his duties for a continuous

                                     - 10 -
<PAGE>
 
period of one hundred and eighty (180) days by reason of disability which
renders Employee physically or mentally incapable (excluding infrequent and
temporary absences due to illness) of performing substantially all of his duties
under this Agreement, Employer may terminate Employee's employment hereunder.
If after a period of disability commences (but prior to termination of
Employee's employment), Employee returns to work for a period of at least twenty
(20) consecutive work days, the period of disability shall be deemed to
terminate and not be counted towards any period of subsequent disability.  For
purposes of this Agreement, Employer, upon the advice of a qualified and
impartial physician, shall determine whether Employee has become physically or
mentally incapable of performing substantially all of his duties under this
Agreement.  Employer shall give Employee (or his guardian, as applicable) thirty
(30) days' written notice of termination of the Term under this Section 7(b)(i).

     (ii) For Good Cause.  Employer may terminate  Employee's employment at any
          --------------                                                       
time for Good Cause (as defined below), by giving reasonable notice under the
circumstances to Employee.  "Good Cause" shall include, without limitation, (A)
a material breach of this Agreement by Employee (where Employee fails to cure
such breach within five (5) days after being notified in writing by Employer of
such breach), (B) Employee's failure to perform his assigned duties without an
excuse that is reasonably acceptable to Employer, (C) Employee engages in an act
(or causes an act) that has a material adverse impact on the reputation,
business, business relationships or financial condition of Employer, (D) the
conviction of Employee of a felony or any crime involving moral turpitude, fraud
or misrepresentation, (E) misappropriation or embezzlement by Employee of funds
or assets of Employer, and (F) Employee's willful refusal to

                                    - 11 -
<PAGE>
 
perform specific directives of the Board which are consistent with the scope,
ethics and nature of Employee's duties and responsibilities hereunder.
Notwithstanding the foregoing, "Good Cause" shall not include a situation
whereby Employer asks Employee to relocate to another city and Employee declines
to do so.  Termination by Employer for Good Cause hereunder based on a material
breach of this Agreement or for other wrongful acts committed by Employee
against Employer, shall not abrogate the rights and remedies of Employer in
respect of the breach or wrongful act giving rise to such termination.

     (c) Termination by Employee.  The Term may be terminated by Employee upon
         -----------------------                                              
thirty (30) days' written notice given to Employer after a material breach
hereof by Employer (where Employer fails to cure such breach within five (5)
days after being notified in writing by Employee of such breach).  Termination
by Employee hereunder shall not abrogate the rights and remedies of Employee in
respect of the breach giving rise to such termination. Upon termination by
Employee following a material breach by Employer, Employee shall have no further
duties or obligations to Employer under this Agreement (except as contemplated
by Section 7(d) below).

     (d) Survival of Sections.  It is agreed that notwithstanding anything
         --------------------                                             
contained in this Agreement to the contrary, Sections 5, 6, the applicable
provisions of 7(b)(ii), 8 and 9 of this Agreement shall survive termination of
the Term.

     8.  Payments by, Obligations of, and Events Affecting the Respective
         ----------------------------------------------------------------

Board in good faith).

     (ii)  Benefits pursuant to any of Employer's employee   benefit plans shall
be payable in accordance with the terms of the instruments applicable thereto.

     (iii)  All unvested options held by Employee under   the ISO Plan will

     (iv)  In the event the Term is terminated due to   the death of Employee,
PRADE shall have the right, in its sole discretion (under the terms of the ISO
Plan), to purchase from the estate of Employee (within ninety (90) days of the
date on which the Term is terminated), vested options held by Employee under the
ISO plan and/or any shares held by the estate of Employee as a result of the
exercise by Employee (or his

                                    - 13 -
<PAGE>
 
estate) of vested options held by Employee under the ISO Plan. The purchase
price of the options and shares contemplated by this Section 8(a)(iv) shall be
the fair market value of such vested options and/or shares as of the date on
which the Term is terminated (as determined by the PRADE Board in good faith).

     (b) Should the Term be terminated by Employer under Section 7(b)(ii) of
this Agreement (for Good Cause):

Agreement:

     (i) Employee shall be entitled to receive:

     (A) Any and all accrued but unpaid base salary  compensation due to
Employee as of the date on which the

                                    - 14 -
<PAGE>
 
Term is terminated (payable within fifteen (15) days of the date on which the
Term is terminated); plus

     (B) full base salary (payable monthly at the  same time Employee would
otherwise be entitled to receive such base salary if Employee were still
employed by Employer) (y) through November 1, 1998 or (z) for a period of twelve
(12) months after the date on which the Term is terminated, whichever period is

     (ii)  Benefits pursuant to any of Employer's employee   benefit plans shall

Employee shall have the option (under the terms of the ISO Plan) to require
PRADE to repurchase (during such ninety (90) day period) vested options held by
Employee under the ISO Plan and/or shares of PRADE's common stock previously
issued pursuant to the exercise of options held by Employee under the ISO Plan.
The purchase price of the options and/or shares contemplated by this Section
8(c)(iv) shall be the fair market value of such vested options and/or shares as

MEMO

To:         Gerard Luyben

From:       Earle Martin     /s/ Earle Martin

Subject:    1997 Salary for Joachim Vollmar

Date:       February 14, 1997

CC:         Pat Donnelly, Joachim Vollmar

Gerard,

I have completed a review of the compensation changes made to Joachim's base 
salary since the beginning of his employment with  PRA and determined that the 
correct amount for 1997 is as follows:

            Monthly compensation            DM   21.000
            x 12 months                         252.000

            Two additional months                42.000
            Total annual salary             DM  294.000

This corrects my previous memo to you stating that the 14 month amount was set 
at DM 262.500.

Please implement effective January 1, 1997.

Thanks.

                    PHARMACEUTICAL RESEARCH ASSOCIATES, INC.


          THIS EMPLOYMENT AGREEMENT (the "Agreement") is made as of the 16th day
                                                                        ----    
of October, 1996, by and between Pharmaceutical Research Associates, Inc., a
Virginia corporation (hereinafter called "Employer"), having its principal
office in the Commonwealth of Virginia, and  Patrick K. Donnelly, (hereinafter
called "Employee").

          WHEREAS, Employer and Employee desire to enter into an agreement for
the employment by Employer of Employee.

          NOW, THEREFORE, in consideration of the foregoing, and for other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties, intending to be legally bound, hereby covenant and
agree as follows:

          1.  Position.  Employer hereby employs Employee and Employee hereby
              --------                                                       
accepts employment in the position of Executive Vice-President, with appropriate
title, rank, status and responsibilities as determined from time to time by
Employer upon the terms and conditions hereinafter set forth.

          2.  Term.  The period of employment under this Agreement shall begin
              ----                                                            
on the date of this Agreement (the "Effective Date"), and shall end on November
1, 1998 (the "First Termination Date"), unless sooner terminated pursuant to
Section 7 hereof.  After the First Termination Date, employment hereunder shall
be deemed to be renewed automatically, upon the same terms and conditions, for
successive periods of one year each, until either party, at least ninety (90)
days prior to the expiration of the First Termination Date or any successive
term, as applicable, shall give written notice to the other of a determination
not to renew such employment.  Notwithstanding the foregoing, Employee's
employment hereunder shall be terminable at any time, and from time to time, in
accordance with the provisions of Section 7 of this Agreement.  Subject to
Section 7(d) of this Agreement, the period during which  (a) Employee is
employed under the terms of this Agreement and (b) this 
<PAGE>
 
                                      -2-

Agreement is in force (other than with respect to the provisions that survive
termination of this Agreement), shall be known hereafter as the "Term".

          3.  Duties.
              ------ 

          (a) During the Term, Employee agrees to use his best efforts in the
business of Employer and to devote his full time, skill, attention and energies
to the business of Employer, and shall not, during the Term, be engaged in any
other business activity which shall be competitive with the business of Employer
or which may (i) interfere with Employee's ability to discharge his
responsibilities to Employer, or (ii) detract from the business of Employer.
The Board of Directors of Employer (the "Board") shall have the power to
determine the specific duties that shall be performed by Employee and the means
and manner by which those duties shall be performed.

          (b) In furtherance of the restrictions on the activities of Employee
set forth in Section 3(a) above, during the Term, Employee agrees:

          (i) not to work either on a part-time or independent contracting
     basis for any other company, business or enterprise without the prior
     written consent of the Board; and

          (ii) not to serve on the board of directors or comparable
     governing body of any other material business, civic or community
     corporation or similar entity without the prior written consent of the
     Board (excluding those boards of directors on which Employee serves as of
     the date of this Agreement, which boards, if any, are listed on EXHIBIT A
     hereto).

          (c) Employee agrees to use his reasonable efforts to impart his skill
and knowledge relating to the business of Employer to such individuals as are
designated by Employer, and to train such individuals in the aspects of the
business with which Employee is familiar.  In addition, at the request of
Employer and without additional compensation, Employee shall use his best
efforts to record and document his knowledge relating to the business of
Employer.

          4.  Base Salary, Increases, Benefits, Expenses.  For all services
              ------------------------------------------                   
rendered by Employee under this Agreement and subject to Section 7 below, during
the Term, Employer shall provide Employee with the following:
<PAGE>
 
                                      -3-

          (a) Commencing on the Effective Date, Employer shall pay to Employee,
in equal bi-monthly installments, a base salary of $125,000 per year.

          (b) Employee shall be eligible for salary increases, which may be
based on performance and/or cost-of-living factors, as determined under the
provisions of any salary policy of Employer that is generally applicable to
Employer's employees, provided that any such increases shall be reviewed and
approved in advance by the Compensation Committee of the Board (the
"Compensation Committee"), and Employee shall be entitled to such other
increases in compensation as are otherwise imposed by the Compensation
Committee, in its discretion, from time to time.

          (c) Employee shall participate in Employer's 1996 Bonus Plan, as such
1996 Bonus Plan currently exists on the date of this Agreement.

          (d) Employee shall participate in Employer's standard benefits
programs, which presently include health, life and disability insurance, as well
as those additional benefits (the "Additional Benefits") currently offered to
Employer's executive staff, including additional life and disability insurance,
health club membership and monthly car allowance.  It is agreed that the nature
and amount of the Additional Benefits, if any, shall be determined from time to
time by the Compensation Committee, in its discretion.   Employer may, at its
election, maintain policies of life and disability insurance on Employee, with
Employer or an affiliate of Employer as beneficiary, and Employee shall
cooperate as necessary to obtain such policies and to keep them in force.
Employee shall be entitled to a total of twenty (20) days of paid vacation per
year.  Employee shall be covered by the holiday policy of the Employer, and,
unless inconsistent with applicable law, by any other pension or retirement
plan, disability benefit plan or any other benefit plan or arrangement of
Employer (other than a medical or life insurance plan) presently or hereafter
existing for the benefit of officers or employees of Employer generally, and
determined by the Compensation Committee to be applicable to Employee.

          (e) Subject to such conditions as Employer may from time to time
determine, Employer shall pay or reimburse Employee for reasonable expenses
incurred by Employee in connection with the business of Employer and the
performance of Employee's duties hereunder.
<PAGE>
 
                                      -4-

          (f) It is understood and agreed that the Compensation Committee will
meet quarterly to review compensation matters of Employer, and will (on at least
an annual basis) set all annual bonus targets, salary increases and benefits to
which Employee shall be entitled to participate.

          (g) It is the intention of Employer to have the Compensation Committee
recommend to the Board of Directors (the "PRADE Board") of PRA International,
Inc., a Delaware corporation and the parent company of Employer ("PRADE"), to
create, shortly after the date of this Agreement, an incentive based option plan
for key employees of Employer (the "ISO Plan").  It is expected that the ISO
Plan will consist of options for common stock of PRADE and will have key terms,
subject to alteration and amendment in the sole discretion of the PRADE Board in
consultation with the Compensation Committee, substantially similar to those set
forth on EXHIBIT B hereto as well as those contemplated by Section 8 of this
Agreement.  At such time as the ISO Plan is created, Employee shall be entitled
to participate therein.

          5.  Confidential Information and Certain Property Matters.
              ----------------------------------------------------- 

          (a) Employee hereby acknowledges that, in the course of his employment
under this Agreement, he will be given access to or otherwise will come into
contact with and/or will possess, and that with respect to Employer's business
he already possesses, information, knowledge, contacts and experience relating
to the businesses, operations, properties, assets, liabilities and financial
condition of Employer and the markets and industries in which it operates,
including, without limitation, information relating to business plans and ideas,
trade secrets, intellectual property, know-how, formulas, processes, research
and development, methods, policies, materials, results of operations, financial
and statistical data, personnel data and customers in and related to the markets
and industries in which Employer operates (the "Confidential Information"),
which are considered by Employer to be valuable, secret, confidential and
proprietary.  Employee hereby acknowledges and agrees that the Confidential
Information is valuable, secret, confidential and proprietary to Employer, and
hereby undertakes and agrees that he shall not, at any time (whether during or
after the expiration of the Term), or for any purpose, make public, disclose,
divulge, furnish, release, transfer, sell or otherwise make available to any
person any of the Confidential Information, or otherwise use any of the same or
allow any of the same to be used for any purpose including, but not limited to,
contacting for any purpose the personnel, customers or suppliers of Employer,
other than as 
<PAGE>
 
                                      -5-

may be permitted to Employee under this Agreement. Notwithstanding the
foregoing, Employee may, without violating this Section 5(a), disclose
Confidential Information if (i) such disclosure is required to comply with a
valid court order or any administrative law order or decree, (ii) Employee gives
Employer advance written notice of the required disclosure so that Employer may,
if it wishes, seek an appropriate protective order and (iii) Employee, in any
event, requests that any disclosed information be afforded confidential
treatment, to the greatest extent possible.

          (b) Employee hereby agrees to promptly and fully disclose to Employer
all Inventions made or conceived by him that would be deemed applicable, useful
or otherwise beneficial to or in respect of, the current business of Employer,
in whole or in part, during his employment with Employer.  For the purposes of
this Agreement, "Inventions" include, but are not limited to, customer list
compilations, machinery, apparatus, products, processes, results of research and
development (including without limitation results that constitute trade secrets,
ideas and writings), computer hardware, information systems, software (including
without limitation source code, object code, documentation, diagrams and flow
charts) and any other discoveries, concepts and ideas, whether patentable or not
(including without limitation processes, methods, formulas, and techniques, as
well as improvements thereof or know-how related thereto, concerning any present
or prospective business activities of Employer).   Any and all Inventions shall
be the absolute property of Employer or its designees, and Employee acknowledges
that he shall have no interest whatsoever in such Inventions.  At the request of
Employer and without additional compensation, Employee (i) shall make
application in due form for United States letters patent and foreign letters
patent on such Inventions, and shall assign to Employer all his right, title and
interest in such Inventions, (ii) shall execute any and all instruments and do
any and all acts necessary or desirable in connection with any such application
for letters patent or in order to establish and perfect in Employer the entire
right, title and interest in such Inventions, patent applications or patents and
(iii) shall execute any instruments necessary or desirable in connection with
any continuations, renewals or reissues thereof or in the conduct of any related
proceedings or litigation.  Except as authorized by Employer in writing,
Employee shall not disclose, directly or indirectly, to any person other than
Employer, any information relating to any Invention or any patent application
relating thereto.

          (c) Employee hereby acknowledges and agrees that the work performed by
Employee pursuant to his employment by Employer will be specifically ordered or
commissioned by Employer, and that such work shall be considered a "work for
hire" as defined in the 
<PAGE>
 
                                      -6-

Copyright Revision Act of 1976 (the "Act"), granting Employer full ownership to
the work and all rights comprised therein. Should any work not fall within the
definition of a "work for hire" as set forth in such Act, Employee hereby
transfers and assigns to Employer full ownership of the copyright to the work
and all rights comprised therein. Employee shall sign all applications for
registration of such copyright as are requested by Employer, and shall sign all
other writings and instruments and perform all other acts necessary or desirable
to carry out the terms of this Agreement.

          6.  Covenant Not to Compete.  (a)  Employee agrees that during the
              -----------------------                                       
Term and for a period of two years thereafter (the "Noncompetition Period"), he
shall not directly or indirectly own, manage, operate, join, advise, consult,
control or participate in the ownership, management, operation or control of, or
be connected in any manner with, any business under any name similar to the name
of Employer or any other person whose principal business is (or the principal
business of any of its affiliates is) competitive with Employer or who proposes
to engage in a business competitive with Employer, or in any department or
division of any other person where such department or division is competitive
with Employer (where the nature of Employer's business is measured (i) if the
competitive act in question occurs during the Term, at the time the competitive
act in question is made by Employee, and (ii) if the competitive act in question
occurs after the Term, at the time Employee's employment is terminated
hereunder).  During the Noncompetition Period, Employee agrees that he shall not
offer to any person any services that compete with or are substantially similar
to those provided by Employer (where the nature of Employer's business,
including the services provided by Employer, are measured (1) if the offer is
made during the Term, at the time the offer is made by Employee, and (2) if the
offer is made after the Term, at the time Employee's employment is terminated
hereunder).

          (b) Employee agrees that he shall not engage in unfair competition 
with Employer during the Noncompetition Period.

          (c) Employee agrees that he shall not, during the Noncompetition
Period (after the Term), other than on behalf of Employer and consistent with
his duties as an employee of Employer, directly or indirectly solicit the trade
of, or trade with, any person who is a client, customer or supplier of Employer
(where all such clients, customers and suppliers are measured at the time
Employee's employment is terminated hereunder) unless Employee receives the
prior written consent of the Board to do so.
<PAGE>
 
                                      -7-

          (d) Employee agrees that he shall not, during the Noncompetition
Period (after the Term), directly or indirectly, solicit or induce (or attempt
to solicit or induce) to leave the employ of Employer for any reason whatsoever,
or hire, any person who (i) was employed by Employer within one year prior to
the time of the act of solicitation or inducement, or (ii) is employed by
Employer at the time of the act of solicitation or inducement.

          (e) During and after the Term, Employee agrees not to disparage
Employer, the parent of Employer, or any of the subsidiaries or affiliates of
Employer.  During and after the Term, Employer agrees not to disparage the
character of Employee.

          (f) Employee hereby specifically acknowledges and agrees that the
provisions of this Section 6 are reasonable and necessary to protect the
legitimate interests of Employer, and that Employee desires to agree to the
provisions of this Section 6.  In the event that any of the provisions of this
Section 6 should ever be held to exceed the time, scope or geographic
limitations permitted by applicable law, it is hereby declared to be the
intention of the parties hereto that such provision be reformed to reflect the
maximum time, scope and geographic limitations that are permitted by such law.

          (g) Employee hereby acknowledges and agrees for himself, and for any
person participating with him in any breach or threatened breach of this Section
6 (the "Other Person"), that, owing to the special, unique and extraordinary
nature of the matters covered by this Section 6, in the event of any breach or
threatened breach by Employee or the Other Person of any of the provisions
hereof, Employer would suffer substantial and irreparable injury, which could
not be fully compensated by monetary award alone, and Employer would not have
adequate remedy at law.  Therefore, Employee agrees that, in such event,
Employer shall be entitled to temporary and/or permanent injunctive relief
against him and any such Other Person, without the necessity of proving actual
damages or of posting bond to enforce any of the provisions of this Section 6,
and he hereby waives for himself and for any such Other Person the defenses,
claims, or arguments that the matters are not special, unique, and
extraordinary, that Employer must prove actual damages, and that Employer has an
adequate remedy at law.

          (h) Employee further agrees that the rights and remedies described in
this Section 6 are cumulative and shall be in addition to and not in lieu of any
other rights and remedies otherwise

available under this Agreement, or at law or in equity, including but not
limited to monetary damages.

          7.  Termination.
              ----------- 

          (a) Basic Termination.  In addition to the termination provisions set
              ------------------                                               
forth in Section 7(b) and Section 7(c)  hereof, the Term shall terminate
pursuant to the applicable provisions of Section 2 hereof and immediately upon
the death of Employee.  Upon termination of the Term under the applicable
provisions of Section 2 hereof or upon the death of Employee, Employer shall
have no further obligation to Employee except as set forth in Section 8 hereof.

          (b) Termination By Employer.  The Term may be terminated by Employer
              ------------------------                                        
under the following circumstances (in each case, upon such termination, Employer
shall have no further obligation to Employee except as set forth in Section 8
hereof):

               (i) Disability.  If during the Term, Employee shall be prevented
                   ----------                                                  
     from performing his duties for a continuous period of one hundred and
     eighty (180) days by reason of disability which renders Employee physically
     or mentally incapable (excluding infrequent and temporary absences due to
     illness) of performing substantially all of his duties under this
     Agreement, Employer may terminate Employee's employment hereunder.  If
     after a period of disability commences (but prior to termination of
     Employee's employment), Employee returns to work for a period of at least
     twenty (20) consecutive work days, the period of disability shall be deemed
     to terminate and not be counted towards any period of subsequent
     disability.  For purposes of this Agreement, Employer, upon the advice of a
     qualified and impartial physician, shall determine whether Employee has
     become physically or mentally incapable of performing substantially all of
     his duties under this Agreement.  Employer shall give Employee (or his
     guardian, as applicable) thirty (30) days' written notice of termination of
     the Term under this Section 7(b)(i).

               (ii) For Good Cause.  Employer may terminate Employee's
                    --------------                                    
     employment at any time for Good Cause (as defined below), by giving
     reasonable notice under the circumstances  to Employee.  "Good Cause" shall
     include, without limitation, (A) a material breach of this Agreement by
     Employee (where Employee fails to cure such breach within five (5) days
     after being notified in writing by Employer of such breach), (B) Employee's
     failure to 
<PAGE>
 
                                      -9-

     perform his assigned duties without an excuse that is reasonably
     acceptable to Employer, (C) Employee engages in an act (or causes an act)
     that has a material adverse impact on the reputation, business, business
     relationships or financial condition of Employer, (D) the conviction of
     Employee of a felony or any crime involving moral turpitude, fraud or
     misrepresentation, (E) misappropriation or embezzlement by Employee of
     funds or assets of Employer, and (F) Employee's willful refusal to perform
     specific directives of the Board which are consistent with the scope,
     ethics and nature of Employee's duties and responsibilities hereunder.
     Notwithstanding the foregoing, "Good Cause" shall not include a situation
     whereby Employer asks Employee to relocate to another city and Employee
     declines to do so.  Termination by Employer for Good Cause hereunder based
     on a material breach of this Agreement or for other wrongful acts committed
     by Employee against Employer, shall not abrogate the rights and remedies of
     Employer in respect of the breach or wrongful act giving rise to such
     termination.

          (c) Termination by Employee.  The Term may be terminated by Employee
              -----------------------                                         
upon thirty (30) days' written notice given to Employer after a material breach
hereof by Employer (where Employer fails to cure such breach within five (5)
days after being notified in writing by Employee of such breach).  Termination
by Employee hereunder shall not abrogate the rights and remedies of Employee in
respect of the breach giving rise to such termination.  Upon termination by
Employee following a material breach by Employer, Employee shall have no further
duties or obligations to Employer under this Agreement (except as contemplated
by Section 7(d) below).

          (d) Survival of Sections.  It is agreed that notwithstanding anything
              --------------------                                             
contained in this Agreement to the contrary, Sections 5, 6, the applicable
provisions of Sections 7(b)(ii), 8 and 9 of this Agreement shall survive
termination of the Term.

          8.  Payments by, Obligations of, and Events Affecting the Respective

          faith).

               (ii) Benefits pursuant to any of Employer's employee benefit
     plans shall be payable in accordance with the terms of the instruments

     faith).

7(b)(ii) of this Agreement (for Good Cause):

               (i) Employee shall be entitled to receive (within fifteen (15)
     days of the date on which the Term is terminated) any and all accrued but
     unpaid base salary compensation due to Employee as of the date on which the
     Term is terminated.

               (ii) Benefits pursuant to any of Employer's employee benefit

                    (B) full base salary (payable monthly at the same time

                    ISO Plan will vest automatically upon any extraordinary
                    event in which any purchaser(s) (whether taken individually

                    of Return (as such term is defined in that certain
                    Stockholders' Agreement attached as Exhibit C to the Stock
                    Purchase Agreement; "IRR") greater than 25% (to the extent
                    that exercise of any options under the ISO Plan do not
                    reduce such IRR below 25%).

                    In addition to the foregoing, 25% of the options under the
                    ISO Plan will vest automatically upon any extraordinary
                    event in which the above stated IRR for any such
                    Purchaser(s) (whether taken individually or as a group) is
                    greater than 33%.

Grant of Options:   Allocation of the options under the ISO Plan will be
                    determined by the PRADE Board in consultation with the
                    Compensation Committee.

          WHEREAS, Employer and Employee desire to enter into an agreement for
the employment by Employer of Employee.

          NOW, THEREFORE, in consideration of the foregoing, and for other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties, intending to be legally bound, hereby covenant and
agree as follows:

          1.  Position.  Employer hereby employs Employee and Employee hereby
              --------

each, upon the delivery by either party, at least ninety (90) days prior to the
expiration of the First Termination Date or any successive term, as applicable,
of written notice to the other of a determination to renew such employment, but

party within such 90-day period to refuse such renewal request.  Notwithstanding
the foregoing, Employee's employment hereunder shall be terminable at any time,
and from time to time, in accordance with the provisions of Section 8 of this

Employee set forth in Section 3(a) above, during the Term, Employee agrees:

     or independent contracting basis for any other company, business or
     enterprise without the prior written consent of the Board; and

              (ii) not to serve on the board of directors or comparable
     governing body of any other material business, civic or community
     corporation or similar entity without the prior written consent of the

     the date of this Agreement, which boards, if any, are listed on Exhibit B
     hereto).

              (c)  Employee agrees to use his reasonable efforts to impart his

of officers or employees of Employer generally, and determined by the
Compensation Committee to be applicable to Employee.

incurred by Employee in connection with the business of Employer and the
performance of Employee's duties hereunder.

              (h)  It is understood and agreed that the Compensation Committee
will meet quarterly to review compensation matters of Employer, and will (on at
least an annual basis) set all annual bonus targets, salary increases and
benefits to which Employee shall be entitled to participate.

          6.  Confidential Information and Certain Property Matters.
              ----------------------------------------------------- 

              (a)  Employee hereby acknowledges that, in the course of his
employment under this Agreement, he will be given access to or otherwise will
come into contact with and/or will possess, and that with respect to Employer's
business he already possesses, information, knowledge, contacts and experience
relating to the businesses, operations, properties, assets, liabilities and
financial condition of PRADE and its subsidiaries and affiliates, including,
without limitation, Employer (collectively, the "Companies") and the markets and
industries in which they operate, including, without limitation, information
relating to business plans and ideas, trade secrets, intellectual property, 
know-how, formulas, processes, research and development, methods, policies,
materials, results of operations, financial and statistical data, personnel data
and customers in and related to the markets and industries in which the
Companies operate (the "Confidential Information"), which are considered by
Employer and the other Companies to be valuable, secret, confidential and
proprietary. Employee hereby acknowledges and agrees that the Confidential
Information is valuable, secret, confidential and proprietary to Employer and
the other Companies, and hereby undertakes and agrees that he shall not, at any
time (whether during or after the
<PAGE>
 
                                      -5-

expiration of the Term), or for any purpose, make public, disclose, divulge,
furnish, release, transfer, sell or otherwise make available to any person any
of the Confidential Information, or otherwise use any of the same or allow any
of the same to be used for any purpose including, but not limited to, contacting
for any purpose the personnel, customers or suppliers of Employer or any other
Company, other than as may be permitted to Employee under this Agreement.
Notwithstanding the foregoing, Employee may, without violating this Section
6(a), disclose Confidential Information if (i) such disclosure is required to
comply with a valid court order or any administrative law order or decree, (ii)
Employee gives Employer advance written notice of the required disclosure so
that Employer or another Company may, if it wishes, seek an appropriate
protective order and (iii) Employee, in any event, requests that any disclosed
information be afforded confidential treatment, to the greatest extent possible.

              (b)  Employee hereby agrees to promptly and fully disclose to
Employer all Inventions made or conceived by him that would be deemed
applicable, useful or otherwise beneficial to or in respect of, the current
business of Employer, in whole or in part, during his employment with Employer.
For the purposes of this Agreement, "Inventions" include, but are not limited
to, customer list compilations, machinery, apparatus, products, processes,
results of research and development (including without limitation results that
constitute trade secrets, ideas and writings), computer hardware, information
systems, software (including without limitation source code, object code,
documentation, diagrams and flow charts) and any other discoveries, concepts and
ideas, whether patentable or not (including without limitation processes,
methods, formulas, and techniques, as well as improvements thereof or know-how
related thereto, concerning any present or prospective business activities of
Employer). Any and all Inventions shall be the absolute property of Employer or
its designees, and Employee acknowledges that he shall have no interest
whatsoever in such Inventions. At the request of Employer and without additional
compensation, Employee (i) shall make application in due form for United States
letters patent and foreign letters patent on such Inventions, and shall assign
to Employer all his right, title and interest in such Inventions, (ii) shall
execute any and all instruments and do any and all acts necessary or desirable
in connection with any such application for letters patent or in order to
establish and perfect in Employer the entire right, title and interest in such
Inventions, patent applications or patents and (iii) shall execute any
instruments necessary or desirable in connection with any continuations,
renewals or reissues thereof or in the conduct of any related proceedings or
litigation. Except as authorized by Employer in writing, Employee shall not
disclose, 
<PAGE>
 
                                      -6-

directly or indirectly, to any person other than Employer, any information
relating to any Invention or any patent application relating thereto.

              (c)  Employee hereby acknowledges and agrees that the work
performed by Employee pursuant to his employment by Employer will be
specifically ordered or commissioned by Employer, and that such work shall be
considered a "work for hire" as defined in the Copyright Revision Act of 1976
(the "Act"), granting Employer full ownership to the work and all rights
comprised therein. Should any work not fall within the definition of a "work for
hire" as set forth in such Act, Employee hereby transfers and assigns to
Employer full ownership of the copyright to the work and all rights comprised
therein. Employee shall sign all applications for registration of such copyright
as are requested by Employer, and shall sign all other writings and instruments
and perform all other acts necessary or desirable to carry out the terms of this
Agreement.

          7.  Covenant Not to Compete.  (a)  Except for passive investments in
              -----------------------                                         
public companies, Employee agrees that during the Term and for a period of two
years thereafter (the "Noncompetition Period"), he shall not directly or
indirectly own, manage, operate, join, advise, consult, control or participate
in the ownership, management, operation or control of, or be connected in any
manner with, any business under any name similar to the name of any of the
Companies or any other person whose principal business is (or the principal
business of any of its affiliates is) competitive with any of the Companies or
who proposes to engage in a business competitive with any of the Companies, or
in any department or division of any other person where such department or
division is competitive with any of the Companies (where the nature of each
Company's business is measured (i) if the competitive act in question occurs
during the Term, at the time the competitive act in question is made by
Employee, and (ii) if the competitive act in question occurs after the Term, at
the time Employee's employment is terminated hereunder).  During the
Noncompetition Period, Employee agrees that he shall not offer to any person any
services that compete with or are substantially similar to those provided by any
of the Companies (where the nature of each Company's business, including the
services provided by such Company, are measured (1) if the offer is made during
the Term, at the time the offer is made by Employee, and (2) if the offer is
made after the Term, at the time Employee's employment is terminated hereunder).

              (b)  Employee agrees that he shall not engage in unfair
competition with any of the Companies during the Noncompetition Period.
<PAGE>
 
                                      -7-

              (c)  Employee agrees that he shall not, during the Noncompetition
Period (after the Term), other than on behalf of any of the Companies and
consistent with his duties as an employee of Employer, directly or indirectly
solicit the trade of, or trade with, any person who is a client, customer or
supplier of any of the Companies (where all such clients, customers and
suppliers are measured at the time Employee's employment is terminated
hereunder) unless Employee receives the prior written consent of the Board to 
do so.

              (d)  Employee agrees that he shall not, during the Noncompetition
Period (after the Term), directly or indirectly, solicit or induce (or attempt
to solicit or induce) to leave the employ of any of the Companies for any reason
whatsoever, or hire, any person who (i) was employed by any of the Companies
within one year prior to the time of the act of solicitation or inducement, or
(ii) is employed by any of the Companies at the time of the act of solicitation
or inducement.

              (e)  During and after the Term, Employee agrees not to disparage
any of the Companies. During and after the Term, Employer agrees not to
disparage the character of Employee.

              (f)  Employee hereby specifically acknowledges and agrees that the
provisions of this Section 7 are reasonable and necessary to protect the
legitimate interests of Employer and the other Companies, and that Employee
desires to agree to the provisions of this Section 7.  In the event that any of
the provisions of this Section 7 should ever be held to exceed the time, scope
or geographic limitations permitted by applicable law, it is hereby declared to
be the intention of the parties hereto that such provision be reformed to
reflect the maximum time, scope and geographic limitations that are permitted by
such law.

              (g)  Employee hereby acknowledges and agrees for himself, and for
any person participating with him in any breach or threatened breach of this
Section 7 (the "Other Person"), that, owing to the special, unique and
extraordinary nature of the matters covered by this Section 7, in the event of
any breach or threatened breach by Employee or the Other Person of any of the
provisions hereof, Employer or one or more other Companies would suffer
substantial and irreparable injury, which could not be fully compensated by
monetary award alone, and Employer would not have adequate remedy at law.
Therefore, Employee agrees that, in such event, Employer or such other Companies
shall be entitled to temporary and/or permanent injunctive relief against him
and any such Other Person, without the necessity of proving actual 
<PAGE>
 
                                      -8-

damages or of posting bond to enforce any of the provisions of this Section 7,
and he hereby waives for himself and for any such Other Person the defenses,
claims, or arguments that the matters are not special, unique, and
extraordinary, that Employer or such other Companies must prove actual damages,
and that Employer or such other Companies has an adequate remedy at law.

              (h)  Employee further agrees that the rights and remedies
described in this Section 7 are cumulative and shall be in addition to and not
in lieu of any other rights and remedies otherwise available under this
Agreement, or at law or in equity, including but not limited to monetary
damages.

              (i)  The provisions of this Section 7 shall inure to the benefit
of and be enforceable by each of the Companies.

          8.  Termination.
              ----------- 

              (a)  Basic Termination.  In addition to the termination provisions
set forth in Section 8(b) and Section 8(c) hereof, the Term shall terminate
pursuant to the applicable provisions of Section 2 hereof and immediately upon
the death of Employee. Upon termination of the Term under the applicable
provisions of Section 2 hereof or upon the death of Employee, Employer shall
have no further obligation to Employee except as set forth in Section 9 hereof.

              (b)  Termination By Employer.  The Term may be terminated by 
Employer under the following circumstances (in each case, upon such termination,
Employer shall have no further obligation to Employee except as set forth in
Section 9 hereof):

              (i)  Disability.  If during the Term, Employee shall be prevented
     from performing his duties for a continuous period of one hundred and
     eighty (180) days by reason of disability which renders Employee physically
     or mentally incapable (excluding infrequent and temporary absences due to
     illness) of performing substantially all of his duties under this
     Agreement, Employer may terminate Employee's employment hereunder.  If
     after a period of disability commences (but prior to termination of
     Employee's employment), Employee returns to work for a period of at least
     twenty (20) consecutive work days, the period of disability shall be deemed
     to terminate and not be counted towards any period of subsequent
     disability.  For purposes of this Agreement, Employer, upon the advice of a
     qualified and impartial physician, shall 
<PAGE>
 
                                      -9-

     determine whether Employee has become physically or mentally incapable of
     performing substantially all of his duties under this Agreement. Employer
     shall give Employee (or his guardian, as applicable) thirty (30) days'
     written notice of termination of the Term under this Section 8(b)(i).

              (ii) For Good Cause.  Employer may terminate Employee's
     employment at any time for Good Cause (as defined below), by giving
     reasonable notice under the circumstances to Employee.  "Good Cause" shall
     include, without limitation, (A) a material breach of this Agreement by
     Employee (where Employee fails to cure such breach within five (5) days
     after being notified in writing by Employer of such breach), (B) Employee's
     failure to perform his assigned duties without an excuse that is reasonably
     acceptable to Employer, (C) Employee engages in an act (or causes an act)
     that has a material adverse impact on the reputation, business, business
     relationships or financial condition of Employer, (D) the conviction of
     Employee of a felony or any crime involving moral turpitude, fraud or
     misrepresentation, (E) misappropriation or embezzlement by Employee of
     funds or assets of Employer, and (F) Employee's willful refusal to perform
     specific directives of the Board which are consistent with the scope,
     ethics and nature of Employee's duties and responsibilities hereunder.
     Notwithstanding the foregoing, "Good Cause" shall not include a situation
     whereby Employer asks Employee to relocate to another city and Employee
     declines to do so.  Termination by Employer for Good Cause hereunder based
     on a material breach of this Agreement or for other wrongful acts committed
     by Employee against Employer, shall not abrogate the rights and remedies of
     Employer in respect of the breach or wrongful act giving rise to such
     termination.

              (c)  Termination by Employee.  The Term may be terminated by 
Employee upon thirty (30) days' written notice given to Employer after a
material breach hereof by Employer (where Employer fails to cure such breach
within five (5) days after being notified in writing by Employee of such
breach). Termination by Employee hereunder shall not abrogate the rights and
remedies of Employee in respect of the breach giving rise to such termination.
Upon termination by Employee following a material breach by Employer, Employee
shall have no further duties or obligations to Employer under this Agreement
(except as contemplated by Section 8(d) below).

              (d)  Survival of Sections.  It is agreed that notwithstanding 
anything contained in this Agreement to the contrary, 
<PAGE>
 
                                      -10-

Sections 6, 7, the applicable provisions of Sections 8(b)(ii), 9 and 10 of this
Agreement shall survive termination of the Term.

     Term is terminated.

              (ii)  Benefits pursuant to any of Employer's employee benefit

          terminated); plus

                    (B)  full base salary (payable monthly at the same time
          Employee would otherwise be entitled to receive such base salary if

              (ii)  Benefits pursuant to any of Employer's employee benefit
          plans shall be payable in accordance with the terms of the instruments
          applicable thereto.

              (iii) All unvested options held by Employee under the ISO Plan

              (iv)  Within ninety (90) days of the date on which the Term is

          Plan) to require PRADE to repurchase (during such ninety (90) day
          period) vested options held by Employee under the ISO Plan and/or
          shares of PRADE's common stock previously issued pursuant to the
          exercise of options held by Employee under the ISO Plan. The purchase
          price of the options and/or shares contemplated by this

          shares referenced in this Section 9(c)(iv) shall only apply to the

          PRADE Board in good faith).

valid, binding and enforceable, then such provision shall be stricken from this
Agreement, and the remaining provisions of this Agreement shall not in any way
be affected or impaired, but shall remain in full force and effect.

the Existing Option Agreement in its entirety in connection with the proposed

     NOW, THEREFORE, in consideration of the premises and the mutual covenants
herein set forth, it is agreed that the Existing Option Agreement shall be
